However, instead of re-using the `Add`, `Multiply` etc. methods, the code is re-written in the operator overloads. The operators should be using their respective methods rather than re-declaring the same code. This is under the assumption that the JIT inlines the methods when they are used in the operator overloads. 49 area-Infrastructure Add Linux/Mac build script A `build.sh` should be added alongside `build.cmd` to build corefx on Linux/Mac. 50 area-System.Numerics Made Quarternion's operator overloads use their respective methods "Operator overloads of Quaternion now utilize their respective methods, and removed redundant ""this"" qualifiers in Quaternion constructor.

" 71 area-System.Numerics Behaviour of `Quaternion.CreateFromAxisAngle` when axis is not a unit vector "The resulting quaternion depends on the length of `axis`. This does not describe a rotation and thus does not match the documentation. There are a few ways to handle this issue: 1. Normalize `axis`, but this incurs a performance hit 2. Add a precondition that `axis.Length()` ≈ 1. But enforcing that pre-condition is about as expensive as 1), so it'd probably need to be a documentation-only precondition. Unfortunately this means that consumers will rely on the current behaviour even if it's undocumented, so I don't think that this is a good solution. 3. Document the current behaviour --- Just for convenience, the relevant source code: ``` /// /// Creates a Quaternion from a vector and an angle to rotate about the vector. /// /// The vector to rotate around. /// The angle, in radians, to rotate around the vector. /// The created Quaternion. public static Quaternion CreateFromAxisAngle(Vector3 axis, float angle) { Quaternion ans; float halfAngle = angle * 0.5f; float s = (float)Math.Sin(halfAngle); float c = (float)Math.Cos(halfAngle); ans.X = axis.X * s; ans.Y = axis.Y * s; ans.Z = axis.Z * s; ans.W = c; return ans; } ``` " 72 area-System.Numerics `Equals` with NaN values (IEEE vs. reflexivity) The built in floating point types compare `NaN` as unequal when using `==` and `!=` (following IEEE semantics) but compare it as equal when using the `Equals` method. Your floating point based types currently use IEEE semantics even for `Equals`. I suggest using the same behaviour as the built in types in your floating point based types like vectors or quaternions. The MSDN documentation of `Equals` contains an exception that allows `A.Equals(A)` to return false on floating point types, so you don't strictly violate its contract. But returning false still breaks hash tables and does not match the behaviour of the built in types, so I consider it a bad idea. This can be avoided by calling `Equals` on the members instead of `==` in the implementation of `Equals` but not in `==` and `!=`. For example with quaternion, replace ``` public bool Equals(Quaternion other) { return (X == other.X && Y == other.Y && Z == other.Z && W == other.W); } ``` with ``` public bool Equals(Quaternion other) { return (X.Equals(other.X) && Y.Equals(other.Y) && Z.Equals(other.Z) && W.Equals(other.W)); } ``` You might want to add tests that check that `==` and `!=` compare all the above cases as unequal, so that they match the IEEE specification. Replace: ``` // Counterintuitive result - IEEE rules for NaN comparison are weird! Assert.False(a.Equals(a)); Assert.False(b.Equals(b)); Assert.False(c.Equals(c)); Assert.False(d.Equals(d)); ``` with: ``` // Equals does not follow IEEE semantics since many consumers rely on equality being reflexive. // This includes collections like `Dictionary` or `HashSet` Assert.True(a.Equals(a)); Assert.True(b.Equals(b)); Assert.True(c.Equals(c)); Assert.True(d.Equals(d)); // Counterintuitive result - IEEE rules for NaN comparison are weird! Assert.False(a == a); Assert.False(b == b); Assert.False(c == c); Assert.False(d == d); Assert.True(a != a); Assert.True(b != b); Assert.True(c != c); Assert.True(d != d); ``` 77 area-System.Xml Some Xml encoding tests lost their encoding Some of Xml tests were testing problematic characters in different Encoding (like Russian characters).

The ToArray() method converts the vector to an array: it puts X at index 0, Y at index 1 and so on.

This means that other libraries can't share the same cache (which can grow by the number of generic instantiations). Furthermore, since the actual call sites affected in PLINQ were already allocating considerably, it is doubtful that PLINQ would benefit from the optimization. We should study if we can design public API in the BCL in the same vein as the new `Array.Empty().` _Before_ we do this, we should: 1. Gather data about how many places we have across the stack that would benefit from these shared allocations and find use cases in more compelling places than PLINQ. 2. Design the API. We can use this issue to discuss and evolve it in to a mini-spec. Here's an idea just to get that ball rolling on that. ``` C# namespace System { public static class CommonAction { public static Action Empty { get; } } public static class CommonFunc { public static Func AlwaysTrue(); public static Func Identity(); public static Func IsInstanceOf(); public static Func Cast(); } } ``` 220 area-System.Console Fix /property:OS=Unix build of System.Console Some resource strings got lost in the move to GitHub.

Some people would like to compile the libraries themselves and they would be missing a lot of inline documentation. **Example** _.NET Framework_ ![Documentation](http://i.imgur.com/ySqyI81.png) _.NET Core_ ![No Documentation](http://i.imgur.com/RvBK6fh.png) " 231 area-System.Text Improve performance of Regex ctor and IsMatch "The Regex class maintains a cache of byte codes, which the Regex ctor indexes into using a key. It uses this seemingly innocuous line to create that key: ``` C# String key = ((int)options).ToString(NumberFormatInfo.InvariantInfo) + "":"" + cultureKey + "":"" + pattern; ``` This, however, has the unfortunate effect of allocating a string for the options, a string array for the five strings to be passed to the String.Concat call generated by the compiler, another string array allocation inside of Concat, and then the resulting string for the whole operation. The cost of those allocations is causing a non-trivial slowdown for repeated Regex.IsMatch calls for simple regular expressions, such as for a phone number (e.g. from the MSDN docs ""^\d{3}-\d{3}-\d{4}$""). This commit adds a new struct key type that just stores the constitutent options, cultureKey, and pattern, rather than creating a string to store them. That key is then what's stored in each entry in the cache. For repeated Regex.IsMatch calls for basic regular expressions like the phone number one previously mentioned, on my machine this improves throughput by ~35%, in large part due to an ~80% reduction in number of allocations, and (for this particular test case) an ~70% reduction in number of bytes allocated (it depends primarily on the length of the pattern and the length of the culture name).

System.Numerics.Vectors.csproj was setting TRACE in Release builds but not in Debug builds. System.Text.RegularExpressions.csproj wasn't setting either DEBUG nor RELEASE constants in either Debug/Release builds, it didn't have optimizations enabled in Release, and it wasn't generating symbols in either. The XML libraries were't setting DEBUG/TRACE in either Debug/Release builds, weren't enabling optimizations in Release builds, and weren't generating symbols in either. DEBUG is important in almost all of these libraries, as they use Debug.\* for asserts and the like. Symbol generation is important for debugging. Optimizations are obviously important (but just to verify I saw significant performance wins in multiple libraries just from turning this on in release). TRACE isn't really important, as none of the libraries do release tracing, but I thought it good hygiene to enable it. 247 area-Meta Add Security transparency Since Code Access Security is a thing of the past with .NET Core, I wouldn't expect permissions or security attributes to be used (or even to exist). I didn't see permissions anywhere in the current code: they seem to have be completely removed from .NET Core as expected. However, [several committed files](https://github.com/dotnet/corefx/search?q=SecurityCritical+OR+SecuritySafeCritical&type=Code) still use `SecurityCriticalAttribute` or `SecuritySafeCriticalAttribute`. Is this a left-over from the .NET framework code? I expect so, since they mean nothing without permission checks. If this is intended, what are the guidelines about using them? 249 area-System.Collections Memory allocation documentation for ImmutableDictionary Keys and Values ## Background As described in #246 (and previously in #147), the `Keys` and `Values` properties of `ImmutableDictionary` cannot be used without incurring memory allocations on the heap. However, a slight modification of user code provides _equivalent_ behavior without these allocations. With allocations: ``` csharp foreach (var key in dictionary.Keys) { ... } ``` Without allocations: ``` csharp foreach (var pair in dictionary) { var key = pair.Key; } ``` ## Suggestion Since updating the `Keys` and `Values` properties to eliminate the allocations would be a breaking change (#246), the only recourse is to update the documentation for these properties to describe steps a user can take to avoid allocations if these properties are used heavily within a particular application. ## Caveat Care must be taken to ensure that the documentation does not read in a way that suggests the `Keys` and `Values` properties should not be used. The properties behave properly and would not be even a measurable source of time spent in the application in nearly all cases. This notice is only meant for users making heavy use of these properties who are also actively working to reduce the memory allocations performed within an especially performance-sensitive section of code. 251 area-System.Text Fix DEBUG constant name It looks like DBG was being used instead of DEBUG at System.Text.RegularExpressions.

There is a `BlobReader` for reading various elements out of blobs, but it is up to the caller to read the right things at the right positions. This was by-design as the library is designed to sit at the lowest level behind the scenes of higher level API such as Reflection proper, Roslyn, or CCI. The challenge with signatures is that they are variable-length and encode tree structures, and each higher level model that could sit on top of System.Reflection.Metadata will have different representations for the trees. We do not want to introduce an API to build a fully-formed tree that then has to be traversed and rewritten to match the actual use case. This proposal is therefore a middle ground between: 1. Here are the bytes and some helpers. Read the spec to decode. (Status quo) 2. Yet another high-level metadata API. (Out-of-scope for this layer) It works as follows: 1. The caller chooses an arbitrary representation, `TType`, for type symbols and implements `ISignatureTypeProvider`. (See full API spec below). 2. Signatures are parsed by recursive descent and the provider is called to create new type nodes: - _Give me the `TType` that represents this primitive_ - _Give me the `TType` that represents this TypeDefinition_ - _Give me the `TType` that represents an array of this other TType_ - _etc._ # Sample Usage Given a suitable `TypeSymbol` and `TypeSymbolProvider : ISignatureTypeProvider`, here is code walking all of the `TypeSymbol`'s for every field, parameter, and return type: ``` C# using (var stream = File.OpenRead(pathToDll)) using (var peReader = new PEReader(stream)) { var reader = peReader.GetMetadataReader(); var provider = new TypeSymbolProvider(); foreach (TypeDefinitionHandle typeHandle in reader.TypeDefinitions) { TypeDefinition type = reader.GetTypeDefinition(typeHandle); foreach (FieldDefinitionHandle fieldHandle in type.GetFields()) { FieldDefinition field = reader.GetFieldDefinition(fieldHandle); TypeSymbol fieldType = field.DecodeSignature(provider); // ... } foreach (MethodDefinitionHandle methodHandle in type.GetMethods()) { MethodDefinition method = reader.GetMethodDefinition(methodHandle); MethodSignature methodSig = method.DecodeSignature(provider); TypeSymbol returnType = methodSig.ReturnType; // ... foreach (TypeSymbol parameterType in methodSig.ParameterTypes) { // ... } } } } ``` # Full API ## Additions to existing types These provide convenience entry points. There are other use cases where you want to parse only part of a signature or a signature that you did not obtain from the metadata reader. For that, the `SignatureDecoder` ``` C# namespace System.Reflection.Metadata { public struct FieldDefinition { public TType DecodeSignature( ISignatureTypeProvider provider, SignatureDecoderOptions options=SignatureDecoderOptions.None); } public struct MemberReference { public TType DecodeFieldSignature( ISignatureTypeProvider provider, SignatureDecoderOptions options=SignatureDecoderOptions.None); public MethodSignature DecodeMethodSignature( ISignatureTypeProvider provider, SignatureDecoderOptions options=SignatureDecoderOptions.None);

These collections should implement the generic collection interfaces to better interoperate with more modern APIs, such as LINQ. Since these collections are already indexable, they should implement `IList` and `IReadOnlyList`, as well as the non-generic `IList` (to be consistent with the generic interfaces). ## Rationale and Usage This is certainly a nice-to-have, but it _is_ a long-standing [request](https://connect.microsoft.com/VisualStudio/feedback/details/469250/capturecollection-groupcollection-and-matchcollection-do-not-implement-icollection-t-and-ienumerable-t) that [developers](http://stackoverflow.com/q/7274422) [still](http://jimlynn.wordpress.com/2009/11/04/why-cant-i-use-linq-on-a-capturecollection/) [ask](http://stackoverflow.com/q/16379433) [about](http://stackoverflow.com/q/4108956). Implementing the generic interfaces will allow these collections to be used more easily with LINQ and interoperate better with more modern framework and library APIs. For example, to use these collections with LINQ right now you have to know about and remember to use `Enumerable.Cast()` to cast the non-generic `IEnumerable` into an `IEnumerable`: ``` c# var captures = from capture in match.Groups.Cast().Last().Captures.Cast() select capture.Value; ``` With these changes you'd no longer have to do that: ``` c# var captures = from capture in match.Groups.Last().Captures select capture.Value; ``` Plus, in the above example, you'd get a performance improvement when using `Enumerable.Last.()` as its implementation has a fast-path for collections that implement `IList`. ## Proposed API ``` c# // DebuggerDisplay and DebuggerTypeProxy added [DebuggerDisplay(""Count = {Count}"")] [DebuggerTypeProxy(typeof(RegexCollectionDebuggerProxy))] // Previously only implemented ICollection public class CaptureCollection : IList, IReadOnlyList, IList { // Existing members public int Count { get; } public Capture this[int i] { get; } public IEnumerator GetEnumerator(); object ICollection.SyncRoot { get; } bool ICollection.IsSynchronized { get; } void ICollection.CopyTo(Array array, int arrayIndex); // Proposed members public void CopyTo(Capture[] array, int arrayIndex); IEnumerator IEnumerable.GetEnumerator(); int IList.IndexOf(Capture item); void IList.Insert(int index, Capture item); void IList.RemoveAt(int index); Capture IList.this[int index] { get; set; } void ICollection.Add(Capture item); void ICollection.Clear(); bool ICollection.Contains(Capture item); bool ICollection.IsReadOnly { get; } bool ICollection.Remove(Capture item); int IList.Add(object value); void IList.Clear(); bool IList.Contains(object value); int IList.IndexOf(object value); IList.Insert(int index, object value); bool IList.IsFixedSize { get; } bool IList.IsReadOnly { get; } void IList.Remove(object value); void IList.RemoveAt(int index); object IList.this[int index] { get; set; } } // DebuggerDisplay and DebuggerTypeProxy added [DebuggerDisplay(""Count = {Count}"")] [DebuggerTypeProxy(typeof(RegexCollectionDebuggerProxy))] // Previously only implemented ICollection public class GroupCollection : IList, IReadOnlyList, IList { // Existing members public int Count { get; } public Group this[int groupnum] { get; } public Group this[String groupname] { get; } public IEnumerator GetEnumerator(); object ICollection.SyncRoot { get; } bool ICollection.IsSynchronized { get; } void ICollection.CopyTo(Array array, int arrayIndex); // Proposed members public void CopyTo(Group[] array, int arrayIndex); IEnumerator IEnumerable.GetEnumerator(); int IList.IndexOf(Group item); void IList.Insert(int index, Group item); void IList.RemoveAt(int index); Group IList.this[int index] { get; set; } void ICollection.Add(Group item); void ICollection.Clear(); bool ICollection.Contains(Group item); bool ICollection.IsReadOnly { get; } bool ICollection.Remove(Group item); int IList.Add(object value); void IList.Clear(); bool IList.Contains(object value); int IList.IndexOf(object value); IList.Insert(int index, object value); bool IList.IsFixedSize { get; } bool IList.IsReadOnly { get; } void IList.Remove(object value); void IList.RemoveAt(int index); object IList.this[int index] { get; set; } } // DebuggerDisplay and DebuggerTypeProxy added [DebuggerDisplay(""Count = {Count}"")] [DebuggerTypeProxy(typeof(RegexCollectionDebuggerProxy))] // Previously only implemented ICollection public class MatchCollection : IList, IReadOnlyList, IList { // Existing members public int Count { get; } public virtual Match this[int i] { get; } public IEnumerator GetEnumerator(); object ICollection.SyncRoot { get; } bool ICollection.IsSynchronized { get; } void ICollection.CopyTo(Array array, int arrayIndex); // Proposed members public void CopyTo(Match[] array, int arrayIndex); IEnumerator IEnumerable.GetEnumerator(); int IList.IndexOf(Match item); void IList.Insert(int index, Match item); void IList.RemoveAt(int index); Match IList.this[int index] { get; set; } void ICollection.Add(Match item); void ICollection.Clear(); bool ICollection.Contains(Match item); bool ICollection.IsReadOnly { get; } bool ICollection.Remove(Match item); int IList.Add(object value); void IList.Clear(); bool IList.Contains(object value); int IList.IndexOf(object value); IList.Insert(int index, object value); bool IList.IsFixedSize { get; } bool IList.IsReadOnly { get; } void IList.Remove(object value); void IList.RemoveAt(int index); object IList.this[int index] { get; set; } } ``` ## Details - There was some discussion as to whether only the read-only interfaces should be implemented, or both the read-only and mutable interfaces. The consensus is to implement both the read-only and mutable interfaces. This is consistent with other collections in the framework. The mutable interfaces are implemented as read-only: mutable members are implemented explicitly and throw `NotSupportedException` (like `ReadOnlyCollection`). - There was an open question as to whether the non-generic `IList` should be implemented as well. These collections are indexable and if `IList` and `IReadOnlyList` are being implemented, `IList` should be implemented as well. This does add several more members, but they are all implemented explicitly so they don't add any new public members to intellisense, and the implementations are very straightforward. - `ICollection.CopyTo` is implemented implicitly (public). - All other new members are implemented explicitly (non-public): - Mutable members are implemented explicitly because these collections are read-only and the mutable members throw `NotSupportedException` (like `ReadOnlyCollection`). - `IList` members are implemented explicitly to hide non-generic members from intellisense. - `IList.IndexOf` and `ICollection.Contains` are implemented explicitly because these methods aren't very useful for these collections and should not be visible in intellisense by default. They're not useful because an implementation using `EqualityComparer.Default` (consistent with other collections) will search the collection using reference equality due to the fact that `Capture`, `Group`, and `Match` do not implement `IEquatable` and do not override `Equals()` and `GetHashCode()`. Further, these types do not have public constructors -- they are created internally by the regex engine, making it very unlikely that you'd want to search for an item in a collection ""A"" that was obtained from collection ""B"". - `IEnumerable.GetEnumerator()` must be implemented explicitly because the non-generic `IEnumerable.GetEnumerator()` is already implemented implicitly and we can't overload on return type. This also precludes returning a `struct` `Enumerator` (for better enumeration performance) because changing the return type of the existing method would be a binary breaking change. As a result, you'll still have to specify the type when using `foreach` (e.g. `foreach (Capture capture in captures)`); you won't be able to use `var` (e.g. `foreach (var capture in captures)`), unfortunately. ## Open Questions - Should `GroupCollection` implement `IDictionary`, `IReadOnlyDictionary`, and `IDictionary`? `GroupCollection` already has a string indexer. Is it worth implementing the dictionary interfaces as part of this? Personally, I'm leaning toward ""no"" because there isn't a compelling scenario for the dictionary interfaces, and they can always be added in the future when needed. ## Pull Request A PR with the proposed changes is available: #1756 ## Updates - Edited this description to make it more of a _speclet_, based on the discussion below and the proposed API Review process. - Some improvements based on feedback from @sharwell. - Fixed existing members. - Added `IList`. These collections are indexable and it would be strange if `IList` and `IReadOnlyList` were implemented alongside `ICollection` but without `IList`. - Added `DebuggerDisplay` and `DebuggerTypeProxy` attributes. - Made `ICollection.CopyTo` implicit (public). " 277 area-System.Text Update regular expressions collections to implement IReadOnlyList Fixes #271 I believe this is the least intrusive path to implementing the requested functionality. I considered the following items but decided to not include them with this pull request. - `GroupEnumerator` is internal, so it might be possible to change the type of `GroupEnumerator.Capture` from `Capture` to `Group`. This would make the explicit cast in the generic `Current` property unnecessary. - I did not update `CaptureCollection` to implement `IReadOnlyDictionary`, primarily because it's a larger change with the addition of the `Keys` and `Values` properties (even if they are explicitly implemented). This should probably be reviewed independently from a straightforward implementation of `IReadOnlyList`. 281 area-System.Diagnostics System.Diagnostics.FileVersionInfo different/incorrect behaviors compared to .NET Framework FileVersionInfo solely depends on System.IO.FileSystem (and all of its dependencies, including System.IO, System.Threading.Tasks, etc) just to do a File.Exists in GetVersionInfo.

The current API review process is designed around the assumption that it is internal-only. We need to rethink this process for an open source world. This issue represents a proposal how this could be handled. It’s not final – any feedback is highly appreciated. ## Process Goals The key goals are: - **Designed for GitHub**. In order to be sustainable and not be a hurdle for contributors the API review process must feel natural to folks familiar with GitHub. - **Efficiency**. Performing API reviews requires looping in a set of experts. We want to conduct API reviews in an agile fashion without randomizing the reviewers or community members. - **Transparency**. We can use the same process for both internal as well as external contributors. This allows contributors to benefit from the results of API reviews even if the implementer isn’t external. ## Overall Process GitHub is generally based around the pull-request model. The idea is that contributors perform their changes in their own fork and submit a pull request against our repository. For trivial code changes, such as typo fixes, we want folks to directly submit a pull request rather than opening an issue. However, for bug fixes or feature work, we want contributors to first start a discussion by creating an issue. For work that involves adding new APIs we'd like the issue to contain what we call a _speclet_. The speclet should provide a rough sketch of how the APIs are intended to be used, with sample code that shows typical scenarios. The goal isn't to be complete but rather to illustrate the direction so that readers can judge whether the proposal is sound. ![Process diagram](https://cloud.githubusercontent.com/assets/5169960/5499091/a6895e2c-86dd-11e4-8b0e-6ba1ae152541.png) ## Steps - **Contributor opens an issue**. The issue description should contain a speclet that represents a sketch of the new APIs, including samples on how the APIs are being used. The goal isn’t to get a complete API list, but a good handle on how the new APIs would roughly look like and in what scenarios they are being used. - **Community discusses the proposal**. If changes are necessary, the contributor is encouraged to edit the issue description. This allows folks joining later to understand the most recent proposal. To avoid confusion, the contributor should maintain a tiny change log, like a bolded “Updates:” followed by a bullet point list of the updates that were being made. - **Issue is tagged as “Accepting PRs”**. Once the contributor and project owner agree on the overall shape and direction, the project owner tags the issue as “Accepting PRs”. The contributor should indicate whether they will be providing the PR or only contributed the idea. - **Coding**. The contributor is implementing the APIs as discussed. Minor deviations are OK, but if during the implementation the design starts to take a major shift, the contributor is encouraged to go back to the issue and raise the concerns with the current proposal. - **Pull request is being created**. Once the contributor believes the implementation is ready for review, she creates a pull request, referencing the issue created in the first step. - **Pull request is being reviewed**. The community reviews the code for the pull request. The review should focus on the code changes and architecture – not the APIs themselves. Once at least two project owners give their OK, the PR is considered good to go. - **Pull is tagged as “Needs API Review”**. The project owner then marks the pull request as “Needs API Review”. - **API review**. Using the information in the pull request we’ll create an APIX file that constitutes the API delta. The API review board meets multiple times a week to review all PRs that are tagged as needing an API review. - **Pull request is updated with the results of the API Review**. Once the API review is complete, the project owner uploads the notes and API HTML diff, including all comments. The project owner also updates the PR accordingly, with either a call to action to address some concerns or a good to go indicator. - **Pull request is merged**. When there are no issues – or the issues were addressed by the contributor, the PR is merged. ## API Design Guidelines The .NET design guidelines are captured in the famous book [Framework Design Guidelines](http://amazon.com/dp/0321545613) by Krzysztof Cwalina and Brad Abrams. A digest with the most important guidelines are available in our [developer wiki](https://github.com/dotnet/corefx/wiki/Framework%20Design%20Guidelines%20Digest). Long term, we'd like to publish the individual guidelines in standalone repo on which we can also accept PRs and -- more importantly for API reviews -- link to. 295 area-System.Diagnostics Fix file name casing in System.Diagnostics.FileVersionInfo.csproj The file on disk is called Interop.manual.cs, not Interop.Manual.cs.

I would prefer not to give the answer away publicly yet, but feel free to contact me by email.

It should provide one. ## Background `TryParse` is a common pattern in .NET which is useful when a potentially invalid string has to be converted to a different representation. As invalid user input is not an exceptional situation, it makes sense to avoid exception overhead (which coincidentally also educates new developers to handle those situations correctly). Regular expressions are not as common in external input as `int` or `DateTime`, however there are situations when regex is an appropriate tool for the power users (e.g. advanced text editor search/replace). If you want to validate the regex as it is being typed (with reasonable throttling), it is useful to have as little overhead as possible. Request for Regex.TryParse (not by me) had [5 votes on Microsoft Connect](http://webcache.googleusercontent.com/search?q=cache:KV6wcz2SJ44J:https://connect.microsoft.com/VisualStudio/feedback/details/331753/regex-should-have-a-static-tryparse-method+) and currently exists on [UserVoice with 3 votes](http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2683916-regex-should-have-a-static-tryparse-method). ## Design Options Originally I wanted to propose `Regex.TryCreate` (which is in line with `Uri.TryCreate` since `Regex` does no have a `Parse` method). However even for power users regexes might not be easy to write, and providing more information than just ""you have failed"" is useful. I can't think of any existing pattern in the BCL that fits this well, but basically something like this would be useful: ``` csharp public class Regex { // existing members… public static RegexParseResult Parse(string pattern); public static RegexParseResult Parse(string pattern, RegexOptions options); // or alternatively we could use a default value for options } public class RegexParseResult { public bool IsSuccess { get; } public Regex Regex { get; } // parser doesn't have to provide more than one, however it would allow it to do so in the future public IReadOnlyCollection Errors { get; } } public class RegexParseError { public string Message { get; } public int Start { get; } public int End { get; } } ``` ### API Concerns It would be useful to know if I am missing some existing common pattern here, so that consistency with other BCL APIs can be provided. I don't like using name `Parse` here either as it invites confusion -- however I can't currently think of a better approach. ## Example Usage ``` csharp public class RegexValidationRule : System.Windows.Controls.ValidationRule { public override ValidationResult Validate(object value, CultureInfo cultureInfo) { var valueString = (string)value; var parseResult = Regex.Parse(valueString); if (!parseResult.IsSuccess) { var errorString = string.Join(NewLine, parseResult.Errors.Select(e => $""{e.Message} at {e.Start}"")); return new ValidationResult(false, errorString); } return ValidationResult.ValidResult; } } ``` ## Compatibility I think adding a new static method should be safe enough.

" 307 area-Meta Is the corefx repo or the dotnet org a good place for key community projects? Forked from #294. from @n8ohu - > I am working on uses a C# wrapper around a cross-platform C library and it would, in my opinion, be beneficial to other developers if it was part of the core; There is really a spectrum of .NET libraries, with one end point being the official corefx distribution and the other a weekend project never to be touched again. What you are proposing is much closer to the former. I think your base question is whether corefx or a peer repo is appropriate for key community-owned projects. Your scenario is C# wrappers over native libraries, but it could also be a pure managed library, too. We are considering a similar plan for our own libraries that don't fit or don't fit yet in corefx. We can and should include community libraries in that thinking. The Mono org seems to embrace community libraries that have broad applicability. We should take some inspiration from that. It's always a fine idea to host a library out of your own GitHub account. At the same time, we are intending the dotnet org to be a center of gravity for .NET library development. That's why we put the corefx repo there (and same will be true for the coreclr one) instead of the Microsoft org. It's likely the case that discoverability will be better in the dotnet org than an arbitrary personal repo.

Currently we have only a single branch that represents what we're shipping for the next update of .NET Core. Clearly this isn't scalable for the product, and we're going to creating branches for future work so PR's that have API changes and destablizing changes get a little more bake time. @joshfree is looking into that. I would like to get the conversation about branching structure out into the open. And to do that, I would like to start by asking: _why_ is a single branch not scalable for the product? I have worked in code bases of various sizes, release schedules, and branching schemes, and my experience is that NOT branching is nearly always preferable to branching. In fact, the most common reasons given for wanting to branch (e.g. disruptive or long-running changes) are exactly the times when branching hurts the most, because it encourages divergence between different works-in-progress, pushing difficult integration decisions farther out and requiring more rework later. Rather than a policy that handles change by branching, I would rather see a policy of trunk-based development that encourages all changes - even incomplete changes - to be merged into master on a frequent basis. This shortens and simplifies the merging process and encourages small refactorings and improvements by reducing the amount of work needed to merge them. Obviously allowing unfinished work to be committed to master requires mechanisms in place to ensure that such work does not affect the releasability of the framework. Mechanisms such as feature flags and branch by abstraction are slightly more complicated to implement in a framework (especially one that is highly tuned for performance) than in a typical application, but not excessively so.

So I am opening this issue in order to continue the discussion here.) To summarize my point (see the [Regex thread](https://github.com/dotnet/corefx/issues/271) for more details): with the addition of IReadOnlyList in .NET 4.5, I don't believe it is appropriate to continue implementing mutable collection interfaces such as IList on immutable collections. The fact that existing immutable collections (including those in the Immutable Collections library) implement these interfaces is not a good enough reason to continue this flawed pattern. This issue is a particular example of the larger question of how .NET Core will evolve, and how much tolerance it has to evolve _away_ from flawed patterns in the .NET Framework. 329 area-Infrastructure Use `nuget restore` instead of `nuget install` See [this line](https://github.com/dotnet/corefx/pull/324#discussion-diff-22273168R41) and the discussion for details. 338 area-System.Text RegexCharClass Improvements and Cleanup Apologies in advance for the large pull request. Normally, I'd break these changes up into separate smaller pull requests, but in this case the changes were all to the same file and some changes build on top of earlier changes, so it was easier to submit as one larger pull request. Each commit is factored appropriately, so it may be easiest to review each commit separately for more sane diffs. The most significant change was to precompute the constants instead of computing the values at runtime in the static constructor. I have a [one-off test](https://gist.github.com/justinvp/0c1b5faf72349b56a2ed) (not intended to be checked-in) that asserts that the precomputed values from the new implementation are equal to the values that would have been computed at runtime using the previous implementation. 340 area-System.Text Support for RegexOptions.Compiled? `RegexOptions.Compiled` isn't currently supported (the option exists but doesn't do anything).

I have the System.Security.Cryptography.Rfc2898DeriveBytes essentially created in a PCL so works in WinRT etc. I'd like to expand on this as Rfc2898DeriveBytes is HmacSha1 based and people are trying to move onto hmacsha256 and upwards nowadays and I'd like to bring this into .NET Core I'd like to start bringing in System.Security.Cryptography namespace into .NET Core. I'll include tests from the test data listed with the cryptographic standards and whatnot where possible. Can I do this? :) 348 area-Meta Updated README.md with recently added projects 349 area-System.Threading TaskHelpers cleanup TaskHelpers.cs is a temporary stop-gap for assemblies that don't yet depend on the latest System.Threading.Tasks contract. This change removes the dependency on the file for those assemblies that do use the latest, changing them to access the Task.CompletedTask, Task.FromCanceled, and Task.FromException members on Task instead of the corresponding workarounds on TaskHelpers. This file should eventually go away entirely. 350 area-System.Console Use StringBuilderCache in additional assemblies "StringBuilderCache maintains a cache of up to a single StringBuilder per thread, avoiding StringBuilder allocations for the common pattern of: ``` C# StringBuilder sb = new StringBuilder(); // ... do some appends return sb.ToString(); ``` and instead enabling: ``` C# StringBuilder sb = StringBuilderCache.Acquire(); // ... do some appends return StringBuilderCache.GetStringAndRelease(sb); ``` It was added to the repo as part of System.IO.FileSystem. This change deploys usage of it through other assemblies. Not all ""new StringBuilder(...)"" usage has been replaced, just those instances that are expected to be most impactful, e.g. tests were ignored, places where StringBuilders are stored into fields were ignored, debug code was ignored, less common members were ignored, etc. Simple microbenchmarks showed measurable improvements as a result. For example, a test around Regex.Replace showed that ~10% of the allocations incurred were for StringBuilder instances; using StringBuilderCache mostly eliminated these and improved throughput by a corresponding ~10%. This will of course vary based on the test employed, but it's a data point. " 352 area-Meta Design document for performance patterns As noted in #351, some patterns which are commonly used in the .NET Framework for performance reasons are not obvious to users who are new to this project. Due to the number of projects which leverage the .NET library as part of their own applications, performance is a particularly sensitive area, especially in regards to [unnecessary] memory allocations. It would be very helpful to have a document explaining commonly used patterns intended to avoid unnecessary memory allocations, and perhaps other techniques which your prior work has indicated are high-value practices for some reason. 361 area-System.Net Ability to set the HttpWebRequest.DefaultMaximumErrorResponseLength on a per request basis I realize the http code hasn't been imported yet.. But it would be really nice if this could be changed in >=4.6 Currently the only way you can set the DefaultMaximumErrorResponseLength for a request is AppDomain wide. We should also be able to be set on a per request basis (like we can do with ServicePoint). 362 area-System.Console Bring back Console.CancelKeyPress We need this so that we can wait on Ctrl + C events in console applications. issue #311 371 area-System.IO Unix Interop Code is platform specific In commits like this: https://github.com/dotnet/corefx/commit/377dde76c5df105a7bab2c0a3002c0d835ff1b07 An attempt has been made to map both structures and constants to C# managed structures. Unix does not have a binary interface for either the constants or the structures, so the definition is likely already wrong for some platforms and will likely be wrong for ports, even within Linux itself. While the structures are constants do change from Unix to Unix a little known quirk is that both structures and constants also change in size, layout and the values in Linux itself. Early versions of Linux chose to emulate the ABI of the host platform, allowing early Linux to easily execute binaries written for the mainstream operating system of the platform. Linux/Alpha copied OSF/1; Linux/SPARC copied SunOS 4; Linux/MIPS some variation of IRIX and so on. This is why Linux includes many of these definitions in /usr/include/arch/XXX, because they are different in each platform. You should do something similar to what Mono.Posix does, which is to have a managed wrapper that talks to a C library that actually performs the native call and marshals the native version to a well-known structure shared with the managed implementation. 377 area-System.Text Regex tests intermittently fail due to memory usage "In RegexLangElementsCoverageTests.cs, there are several checks related to the total memory usage of the test: ``` CSharp // ** RegexLangElementsCoverageTests.cs ** double maxAcceptablePercentDifference = .3; startWorkingSet = GC.GetTotalMemory(true); ... endWorkingSet = GC.GetTotalMemory(true); percentDifference = ((double)Math.Abs(startWorkingSet - endWorkingSet)) / startWorkingSet; if (maxAcceptablePercentDifference < percentDifference) { Console.WriteLine(""Err_004888anied Total memory increased significantly there may be a memory leak""); Console.WriteLine(""Percent Difference={0}, Max Acceptable Percent Difference={1}, Start Working Set={2}, End Working Set={3}"", percentDifference, maxAcceptablePercentDifference, startWorkingSet, endWorkingSet); iCountErrors++; } ``` I think this check may be causing us more bad than good. I'm not sure what GC.GetTotalMemory takes into consideration, but this logic might also be getting tripped up by the fact that we have multiple tests running in parallel. Also, in general, this seems like a bit of a flaky check in the first place; it fails around 10% of the time for me, I would say. Anyone opposed to removing these checks, or at least making it not an error?

Is this kind of inconsistent formatting normal and acceptable? Is there a preference for how new code should be formatted? " 384 area-System.Collections Application of ObsoleteAttribute to legacy collection types As mentioned in #370, the lack of `[Obsolete]` on certain legacy types in `System.Collections.Specialized` could be confusing to developers. In general I support the use of ObsoleteAttribute, but for this particular library I would recommend it only be applied to types which have well-known newer (better) alternatives. I'm working on the following table... | Legacy Type | Replacement | | --- | --- | | `BitVector32` | No direct replacement? | | `HybridDictionary` | No direct replacement? | | `IOrderedDictionary` | No direct replacement? | | `ListDictionary` | No direct replacement? | | `NameObjectCollectionBase` | No direct replacement? | | `NameValueCollection` | No direct replacement? | | `OrderedDictionary` | No direct replacement? | | `StringCollection` | `List` | | `StringEnumerator` | Only used with `StringCollection` (not marked obsolete?) | | `StringDictionary` | `Dictionary` | 386 area-Infrastructure Jenkins connection abort issues and associated issues with subsequent runs Seeing intermittent issues with Windows remoting in Jenkins.

And I asked: > So if you accept this suggestion (adding the generic interfaces to these types), the changes will have to be added to .NET 4.6 as well? How much time is left to make changes to .NET 4.6? And @weshaggard responded: > Yes @justinvp any types that already exist on the full desktop framework will need to be updated there as well if they are updated in .NET Core. We have a high level goal of making code written for .NET work no matter what .NET platform you are targeting. As for how much time is left to add new public APIs to .NET 4.6 at this point we are not accepting any more unless they are critical. > > With that said we fully expect .NET Core to evolve much more quickly then the full .NET framework that ships in Windows. We just have to be aware that any changes need to eventually make it there as well so while thinking about breaking changes you cannot just consider .NET Core you must consider the other platforms as well. If we don't do that then we risk diverging the platforms and making .NET development as a whole more difficult. I think it'd be worth adding this to one of the wiki pages so it is clear to everyone that types in .NET Core that exist in the full .NET Framework must be binary compatible. I don't think this is explicitly stated anywhere currently. 395 area-System.Runtime String comparer for sorting numeric strings logically "## Rationale For sorting purposes it's common to need portions of strings containing numbers to be treated like numbers. Consider the list of strings `""Windows 7"", ""Windows 10""`. Using the `Ordinal` `StringComparer` to sort the list one would get ``` Windows 10 Windows 7 ``` but the desired ascending logical sort would be ``` Windows 7 Windows 10 ``` ## Proposed API ```diff namespace System { public class StringComparer { + public static StringComparer Create(CultureInfo culture, CompareOptions options); } } namespace System.Globalization { public enum CompareOptions { + NumericOrdering = 0x00000020 } } ``` ## Usage ```cs var list = new List { ""Windows 10"", ""Windows 7"" }; list.Sort(StringComparer.Logical); // List is now ""Windows 7"", ""Windows 10"" ``` This would also be good for sorting strings containing IP addresses. ## Details * `Logical` is a convenience property equivalent to the result of `Create(CultureInfo.CurrentCulture, CompareOptions.Logical)` * `LogicalIgnoreCase` is a convenience property equivalent to the result of `Create(CultureInfo.CurrentCulture, CompareOptions.Logical | CompareOptions.IgnoreCase)` * Non-numeric sequences will be evaluated with the culture provided. * Numeric sequences will be determined by the result of `Char.IsDigit`. * All UTF-16 digits will be supported and are manually parsed using `Char.GetNumericValue`. * Only positive integral values without digit separators will be supported directly. * Numbers will be treated as `ulong`s. Logic for overflows will have to be considered. * The string `Windows 8.1` would be considered 4 sequences. The `Windows ` would be a string sequence, the `8` would be a numeric sequence, the `.` would be another string sequence, and the `1` would be another numeric sequence. * This API could later be expanded to include support for allowing signs, decimals, and digit separators through the use of overloads accepting a `NumberStyles` parameter. * When a numeric and string sequence are considered at the same time the numeric sequence always comes before the string sequence so when sorting the following list, `""a"", ""7""` the number `7` will be sorted before the letter `a`. * Existing methods that take a `CompareOptions` parameter as input will need to be updated to support the new `Logical` member. ## Open Questions * Should `CompareOptions.Logical` be implemented as the flag option `SORT_DIGITSASNUMBERS` to the `dwCmpFlags` parameter of [`CompareStringEx`](https://msdn.microsoft.com/en-us/library/windows/desktop/dd317761(v=vs.85).aspx)? Using it's implementation should be more efficient but later expanding support for `NumberStyles` will require a re-implementation with matching behavior. ## Updates * Added `Logical` and `LogicalIgnoreCase` properties. * Added support for all UTF-16 digits. * Added more `CreateLogical` overloads to match the `Create` method. * Added retrieval of the `NumberFormatInfo` from the `StringComparer` parameter when not explicitly provided and is a `CultureAwareComparer`. * Removed `CreateLogical` overloads that matched the `Create` method. * Switched to only supporting positive integral values without digit separators. * Added consideration of comparing a numeric sequence with a string sequence. * Added the flag member `CompareOptions.Logical` and changed `CreateLogical` to be just an overload of `Create`." 396 area-Meta Update README.md description of legacy collections 398 area-System.Diagnostics Refactor System.Diagnostics.FileVersionInfo with PAL Introduce a Windows and Unix build for System.Diagnostics.FileVersionInfo.dll.

On my machine, the tests as they are after the PR do take ~15 seconds to run as part of the build.

Implementing a Shuffle method is not really hard but it does require like 10 lines of code and people often wonder where to put these so they just prefer quick and dirty solutions like abusing sort methods with random sort key or even worse random comparison. These methods are far from ideal both because they depend on implementation details of the sorting methods and because they are less effective than the ideal O(N) implementation. ## Proposed API Methods on Array: ``` C# public static void Shuffle(T[] array) public static void Shuffle(T[] array, int index, int length) public static void Shuffle(T[] array, Random rng) public static void Shuffle(T[] array, int index, int length, Random rng) ``` Methods on List ``` C# public void Shuffle() public void Shuffle(Random rng) ``` ## Details The Shuffle method on Array has an overload that can be used to shuffle just part of the array. This is in line with existing Array methods like Sort and Copy and can be useful when implementing Shuffle on List where only the elements of the List will be shuffled without shuffling the full capacity of the list. I also suggest adding an instance Shuffle method on List since this is the most common usage of such a method. 464 area-System.ComponentModel Fix inverted documentation between two methods I just noticed this documentation mistake, the two method descriptions were swapped. 465 area-System.Linq Re-enable PLINQ tests Re-issuing #459 against v1.0 branch.

Currently developers would have to implement their own methods in an extension class or use `Math.Max` and `Math.Min` together. The proposed API will shorten the amount of code needed and increase readability. Two examples on how we currently can clamp in .NET: ``` C# int result = Math.Max(Math.Min(value, 100), 0); ``` ``` C# public static class Ext { // Source: http://stackoverflow.com/a/2683487/1455541 public static T Clamp(T val, T min, T max) where T : IComparable { if (val.CompareTo(min) < 0) return min; else if(val.CompareTo(max) > 0) return max; else return val; } } // Somewhere in the codebase int result = Ext.Clamp(value, 0, 100); ``` The proposed API would turn that into: ``` C# int result = Math.Clamp(value, 0, 100); ``` # Proposed API 1 - Specialized ``` C# public static class Math { public static Byte Clamp(Byte value, Byte min, Byte max); public static Decimal Clamp(Decimal value, Decimal min, Decimal max); public static Double Clamp(Double value, Double min, Double max); public static Int16 Clamp(Int16 value, Int16 min, Int16 max); public static Int32 Clamp(Int32 value, Int32 min, Int32 max); public static Int64 Clamp(Int64 value, Int64 min, Int64 max); public static SByte Clamp(SByte value, SByte min, SByte max); public static Single Clamp(Single value, Single min, Single max); public static UInt16 Clamp(UInt16 value, UInt16 min, UInt16 max); public static UInt32 Clamp(UInt32 value, UInt32 min, UInt32 max); public static UInt64 Clamp(UInt64 value, UInt64 min, UInt64 max); } ``` This proposed version mimics the way current `System.Math` methods do it. # Proposed API 2 - IComparable Because this is a new API addition it can also be possible to have smaller implementation using generics that should cover all the cases. ``` C# public static class Math { public static T Clamp(T value, T min, T max) where T : System.IComparable; } ``` # Open Questions - If the api addition is going to be implemented should it be implemented as Proposed API 1 or 2? 468 area-System.Text Spelling fixes for System.Text.RegularExpressions Just fixing a handful of spelling errors in comments. 470 area-Meta Do not use optional arguments on public APIs As part of the [discussion](https://github.com/dotnet/apireviews/tree/master/2015-01-14-misc#110-add-async-documentelement-loading-for-xlinq) around adding async document/element loading for XLINQ (#110) it was mentioned using optional arguments (commonly called optional parameters). **PLEASE, DON'T USE IT ON PUBLIC APIS!!!** Before there were optional arguments the problem of a large number of possible parameters for an API already existed. And since we are talking about XML, look at how `XmlReader` and `XmlWritter` solved it: - [public static XmlReader Create(TextReader input, XmlReaderSettings settings)](http://referencesource.microsoft.com/#System.Xml/System/Xml/Core/XmlReader.cs,6375d7745e42dee9) - [public static XmlWriter Create(XmlWriter output, XmlWriterSettings settings)](http://referencesource.microsoft.com/System.Xml/a.html#c6b2420e91f21e33) Taking advantage of object initialization, calling it looks like optional arguments: ``` XmlReader.Create(reader, new XmlReaderSettings{ IgnoreWhitespace = true }); ``` (I'm going to propose more type inference for cases like this: [Do not require type specification for constructors when the type is known #35](https://github.com/dotnet/roslyn/issues/35)) It's extensible. Another setting can always be added with proper defaults and without breaking existing code. And those settings also become something that can be passed around. Imagine that the original API used optional arguments and there was only one `Save` method. How would you keep that and now add an `CancellationToken` parameter? 482 area-System.Xml Simple cleanup in XDocument classes 484 area-System.Xml "Explicitly marked XDocument private methods with ""private"" keyword" The `private` keyword was used for fields within the XDocument classes but not the method definitions. Updated for consistency. 489 area-System.Numerics Add primitive structs Rectangle and Point System.Drawing, System.Windows, and XNA all implement nearly-identical structures to represent points and rectangles. Given the verbosity of a correct implementation, many library developers re-use an existing implementation, and tie their public APIs to (non-core-compatible) dependencies. Offering primitives like Point, Rectangle (as well as PointF, RectangleF, and Color) would make it much easier for libraries to be compatible with each other. Or, is there a de-facto standard nuget package for these structs that we can promote? 490 area-System.Runtime Allow the Math methods to return float values I find myself casting returned results from Math methods into floats constantly, even if only floats are supplied as parameters for that method. Many developers don't need the accuracy of a double and floats works fine, many other numeric structs store their values are floats too (such as a Vector2). While explicit casting doesn't hurt anyone there are other classes I have come by that return a float if the supplied parameter(s) is float only. This wouldn't really be considered a new API addition, all it would do is add overloaded methods that accepts floats as parameters and returns a float (could call the Double version of the Method underneath to avoid code duplication and cast back). If any of the parameters become a double then the double version of the Method would be called and a double value would return. I would like feedback on what other people think before implementing it. 492 area-System.Collections statistic distribution generator I am thinking to add some random generators that obeys specific statistic distribution functions (like normal, binomial, geometric and so on) and also makes the random generator usable as IEnumerable to be easier to use in line or sequence expressions. There is a great paper that covers the ability to obtain sampling functions by composing other sampling functions that is quite nice to express via IEnumerable and IEnumerator. Suck functions can be very useful to obtain numbers that follow a specific law, for example to be used in generating correct weights to initialise untrained neural networks or similar scenarios. 494 area-System.Runtime Consider exposing extension methods for System.Array .Net 2 convenience methods With .net 2.0, `System.Array` was given a set of convenient LINQ like methods like those present on `List`. Unlike `List`, they were added as static methods. While, LINQ does offer some of these methods these variants do offer some differences/benefits as they are A: Optimized for arrays. B: Evaluated immediately. C: Always produce an array. These methods are:: ``` csharp AsReadOnly BinarySearch ConvertAll Exists Find FindAll FindIndex FindLast FindLastIndex ForEach IndexOf LastIndexOf Sort TrueForAll ``` Some of these offer no real benefit over LINQ, but others can be very useful especially in array heavy APIs like Reflection. Primarily `ConvertAll` and `FindAll`. These methods would also make it easier to work with arrays. There would be no clash with existing LINQ methods as they have different names. 496 area-System.Xml Reformat Xml code Guidelines were updated few times since the last time it was done. 497 area-Meta Remove non-cancellable overloads from async APIs I'd like to start discussion on removing the convenience overloads that call a cancellable API with `CancellationToken.None`: `Task DoAsync() { return DoAsync(CancellationToken.None); }` I think these overloads bloat the API and if you've got a large number of parameters, can be error-prone to implement. I also believe they encourage poor design: consider that a great majority of async code either already does or should support cancellation. The use of these APIs should be relatively rare in good code. 498 area-System.Collections HashSet constructor performance tuning for ISet "As it is currently, `HashSet` has a constructor that takes `IEnumerable`. `var set1 = new HashSet{2,3,4};` `var set2 = new HashSet(set1); // binds against ctor..(IEnumerable)` This works nicely, but the fact that we are ""copying/cloning"" from `ISet` is not being taken advantange of. If we have `HashSet` with ~10000 elements, **there is no efficient way to create a copy of it**. Instead, current implementation will call internally `AddIfNotPresent` for each element in given `IEnumerable`, eg, do an expensive element lookup for each item that is being added (to check if it doesn't exist in our current `HashSet`). This does not have to be the case. `ISet` already promises us the uniqueness. Let me know if this is something of interest, I would like to work on that. " 503 area-Meta Make use of Code Contracts where ever applicable. I wonder the reason why while the code contracts are part of BCL and it is a research project of Microsoft, only some of the API makes use of it. This this is effectively preventing making use of code contracts for the end consumers as well. I would appreciate at least if you can make use of Code Contracts on the public surface API. 507 area-System.Collections Specification tests for collection interfaces In the last [API review](https://github.com/dotnet/apireviews/tree/master/2015-01-14-misc#follow-ups-for-api-review-board), @KrzysztofCwalina mentioned that it would be nice to have a set of tests that can serve as specifications for the expected behavior of the built-in collection interfaces. These tests could be used by people creating types which implement these interfaces to ensure that their implementations match the specification. I love this idea, and would love to help create the suite. Is this something that the community can engage on? 516 area-Meta Replace hand-rolled tests for exceptions with xunit's Assert.Throws There is a lot of hand-rolled exception checking in various test code.

The class constructors below may be added: ``` csharp public Dictionary(int capacity, float loadFactor); public Dictionary(int capacity, float loadFactor, IEqualityComparer comparer) ``` Simirlarly to `Java`'s `HashMap` class constructor: ``` java public HashMap(int initialCapacity, float loadFactor); ``` When the `load factor` is not known, it should take a default value, for example `0.75F`.

LINQ, lambdas and immutability are only a few examples. In my eyes this makes the real difference between Java and .NET Solving the [null reference problem](http://www.infoq.com/presentations/Null-References-The-Billion-Dollar-Mistake-Tony-Hoare) would be the next great addition to the .NET framework borrowed from functional languages. So in this issue I want to propose the addition of a [Option type](http://en.wikipedia.org/wiki/Option_type) to the .NET Framework. # Background Taken from https://github.com/louthy/language-ext#null-reference-problem: > null must be the biggest mistake in the whole of computer language history. I realise the original designers of C# had to make pragmatic decisions, it's a shame this one slipped through though. So, what to do about the 'null problem'? > > null is often used to indicate 'no value'. i.e. the method called can't produce a value of the type it said it was going to produce, and therefore it gives you 'no value'. The thing is that when 'no value' is passed to the consuming code, it gets assigned to a variable of type T, the same type that the function said it was going to return, except this variable now has a timebomb in it. You must continually check if the value is null, if it's passed around it must be checked too. > > Option works in a very similar way to Nullable except it works with all types rather than just value types. It's a struct and therefore can't be null. An instance can be created by either calling Some(value), which represents a positive 'I have a value' response; Or None, which is the equivalent of returning null. > > So why is it any better than returning T and using null? It seems we can have a non-value response again right? Yes, that's true, however you're forced to acknowledge that fact, and write code to handle both possible outcomes because you can't get to the underlying value without acknowledging the possibility of the two states that the value could be in. This bulletproofs your code. You're also explicitly telling any other programmers that: ""This method might not return a value, make sure you deal with that"". This explicit declaration is very powerful. # Rationale and Usage So basically the `Option` type enforces developers to check if a return value has really a value. An example function returning an option would be something like this: ``` public Option GetCacheValue(string key) { if(cache.Keys.Contains(key)) { return cache[key]; //return new Some(cache[key]) //return new Option(cache[key]); } else { return Option.None; //return new Option(); } } ``` The consumer code would then look like this: ``` string value = GetCacheValue(key).Match( some: v => v, none: () => ""this is the default value"" ) ``` # Proposed API ``` public struct Option { // For creating a None public Option(); public Option(T value) public static readonly Option None = new Option(); public bool IsNone {get; }; public bool IsSome { get; } public static implicit operator Option(T value) public static implicit operator Option(OptionNone none) public TReturn Match(Func some, Func none); public static Option Some(T value); } ``` # Details - This was mainly inspired by https://github.com/louthy/language-ext/blob/master/LanguageExt.Core/Option.cs of @louthy # Open questions - [ ] Should there be a public `Value` property as an alternative to Match? - [ ] In which assembly would this be correct? Namespace? - [ ] Should Option be a struct (security, since it cannot be null) or an interface (usability, since `Option` is then also an `Option`)? Thoughts?

Use selector (of priority stored inside the value) or not (5 APIs difference) 5. Use tuples `(TElement element, TPriority priority)` vs. `KeyValuePair` * Should `Peek` and `Dequeue` rather have `out` argument instead of tuple? 6. Is `Peek` and `Dequeue` throwing useful at all? ----------------------------------------------------------------------------------------------- # Original Proposal Issue https://github.com/dotnet/corefx/issues/163 requested the addition of a priority queue to the core .NET collection data structures. This post, while a duplicate, is intended to act the formal submission to the corefx API Review Process. The issue contents are the _speclet_ for a new System.Collections.Generic.PriorityQueue type. I will be contributing the PR, if approved. ## Rationale and Usage The .NET Base Class Libraries (BCL) currently lacks support for ordered producer-consumer collections. A common requirement of many software applications is the ability generate a list of items over time and process them in an order different from the order they were received in. There are three generic data structures within the System.Collections hierarchy of namespaces that supported a sorted collection of items; System.Collections.Generic.SortedList, System.Collections.Generic.SortedSet, and System.Collections.Generic.SortedDictionary. Of these, SortedSet and SortedDictionary are not appropriate for producer-consumer patterns that generate duplicate values. The complexity of SortedList is Θ(n) worst case for both Add and Remove. A much more memory and time efficient data structure for ordered collections with producer-consumer usage patterns is a priority queue. Other than when capacity resizing is necessary, worse case insertion (enqueue) and remove top (dequeue) performance is Θ(log n) - far better than the existing options that exist in the BCL. Priority queues have a wide degree of applicability across different classes of applications. The Wikipedia page on Priority Queues offers a list of many different well understand use cases. While highly specialized implementations may still require custom priority queue implementations, a standard implementation would cover a broad range of usage scenarios. Priority queues are particularly useful in scheduling the output of multiple producers, which is an important pattern in highly parallelized software. It's worth noting that both the C++ standard library and Java offer priority queue functionality as part of their basic APIs. ## Proposed API ``` C# namespace System.Collections.Generic { /// /// Represents a collection of objects that are removed in a sorted order. /// /// Specifies the type of elements in the queue.

Items with a greater comparison value will be returned first. (descending order) - Time complexities: | Operation | Complexity | Notes | | --- | --- | --- | | Construct | Θ(1) | | | Construct Using IEnumerable | Θ(n) | | | Enqueue | Θ(log n) | | | Dequeue | Θ(log n) | | | Peek | Θ(1) | | | Count | Θ(1) | | | Clear | Θ(N) | | | Contains | Θ(N) | | | CopyTo | Θ(N) | Uses Array.Copy, actual complexity may be lower | | ToArray | Θ(N) | Uses Array.Copy, actual complexity may be lower | | GetEnumerator | Θ(1) | | | Enumerator.MoveNext | Θ(1) | | - Additional constructor overloads that take the System.Comparison delegate were intentionally omitted in favor of a simplified API surface area. Callers can use Comparer.Create to convert a function or Lambda expression to an IComparer interface if necessary. This does require the caller to incur a one-time heap allocation. - Although System.Collections.Generic is not yet part of corefx, I propose that this class be added to corefxlab in the meantime. It can be moved to the primary corefx repository once System.Collections.Generic are added and there is consensus that its status should be elevated from experimental to an official API. - An IsEmpty property was not included, since there is no additional performance penalty calling Count. The majority of the collection data structures do not include IsEmpty. - The IsSynchronized and SyncRoot properties of ICollection were implemented explicitly as they are effectively obsolete. This also follows the pattern used for the other System.Collection.Generic data structures. - Dequeue and Peek throw an InvalidOperationException when the queue is empty to match the established behavior of System.Collections.Queue. - IProducerConsumerCollection was not implemented as its documentation states that it is only intended for thread-safe collections. ## Open Questions - Is avoiding an additional heap allocation during calls to GetEnumerator when using foreach a strong enough rationale for including the nested public enumerator structure? - Should CopyTo, ToArray, and GetEnumerator return results in prioritized (sorted) order, or the internal order used by the data structure? My assumption is that the internal order should be returned, as it doesn't incur any additional performance penalties. However, this is a potential usability issue if a developer thinks of the class as a ""sorted queue"" rather a priority queue. - Does adding a type named PriorityQueue to System.Collections.Generic cause a potentially breaking change? The namespace is heavily used, and could cause a source compatibility problem for projects that include their own priority queue type. - Should items be dequeued in ascending or descending order, based on the output of IComparer? (my assumption is ascending order, to match the normal sorting convention of IComparer). - Should the collection be 'stable'? In other words, should two items with equal IComparison results be dequeued in the exact same order they are enqueued in? (my assumption is this isn't needed) ## Updates - Fixed complexity of 'Construct Using IEnumerable' to Θ(n). Thanks @svick. - Added another option question regarding whether the priority queue should be ordered in ascending or descending order compared to the IComparer. - Removed NotSupportedException from explicit SyncRoot property to match behavior of other System.Collection.Generic types instead of using the newer pattern. - Made the public GetEnumerator method return a nested Enumerator struct instead of IEnumerable, similar to the existing System.Collections.Generic types. This is an optimization to avoid a heap (GC) allocation when using a foreach loop. - Removed ComVisible attribute. - Changed complexity of Clear to Θ(n). Thanks @mbeidler.

The expected sequence is `[0, 1, 2, 3, 0, 1, 2, 3]`, and the actual result of this `Concat(...)` is `[0, 0, 1, 1, 2, 2, 3, 3]`. Adding `AsOrdered()` to the inner range has no effect. There is no history of changes for `Concat(...)`, although the actual problem may be elsewhere. This issue is **NOT** present in the current .NET distribution (ie, creating a brand-new C# project won't reproduce the error, this is something happening in corefx, which is a really good thing)/ Generating the parallel sequence via `Enumerable.Range(...).AsParallel().AsOrdered()` _also_ fails, but seems to be putting the elements in non-deterministic order (the last run was `[0, 1, 1, 2, 2, 3, 0, 3]`). However, generating the sequence via `leftData.AsParallel().AsOrdered().Concat(leftData.AsParallel())` returns the expected sequence (both of them have to be generated via backing arrays, or you get the re-ordered or non-deterministic results). `ParallelEnumerable.Range(...).AsOrdered()` _does_ return an ordered sequence. The following test succeeds: ``` int count = 8; ParallelQuery elements = ParallelEnumerable.Range(0, count).AsOrdered().Select(x => (object)x); int counter = 0; Assert.All(elements.Cast(), x => Assert.Equal(counter++, x)); Assert.Equal(count, counter); ``` 585 area-System.Linq Fix PLINQ concat ordering bug For .NET Core, some (temporary) changes were made to PLINQ to remove some of its usage of generics in order to workaround some (temporary) constraints of the runtime.

This commit fixes all of them (issues #176 and #240), except for #235, which is addressed by a separate PR (#585) for a product bug rather than test issues. I did not do a general pass through the PLINQ tests, even though they could use it. PlinqModesTests - There's an explicit comment at the top of the test that it's not meant for DOP==1 (it verifies that work happens in parallel), and then apparently we were surprised when it was failing on single core machines that result in DOP == 1 ;) UnionIntersectDistinctTests.RunOreredUnionTest1 - There's no reason this test should fail. If it does, there's a bug to be investigated. I'm assuming it was actually stalling because of another test running with it concurrently. WithCancellationTests - A bunch of these tests were scheduling tasks to asynchronously cancel/dispose a query, and the query was written to take a certain amount of time to hopefully allow for cancellation to take place. But it appears as part of the tests being ported, those timeouts were simply commented out, making it extremely likely the tests would fail. I've just rewritten them to do the cancellation as part of the query's execution rather than using a separate asynchronous task. I also deleted some duplicative tests. And I made some tests that still did explicit delays/timeouts to be OuterLoop. 594 area-System.Runtime Parsing string to enum with digit as first char takes a very long time "Note: This has to do with mscorlib. https://github.com/Microsoft/referencesource sent me here, but this doesn't look like the place where this is handled. Am I right? When parsing strings to enums with TryParse, in some cases this takes way longer than in all the other cases. After a bit of research I found that all the strings with a digit as first char are slower. This is due to the attempt to parse the string to the underlying type (https://github.com/Microsoft/referencesource/blob/master/mscorlib/system/enum.cs#L441) with a Convert.ChangeType, which can throw an exception, because further down the line it uses (for example) Int32.Parse instead of TryParse (https://github.com/Microsoft/referencesource/blob/master/mscorlib/system/convert.cs#L1121). The time it takes to create the Exception is significant. In my project I ended up writing a new Enum parser to circumvent this issue. ""Something"": 240.49 ns per parse ""1Somethin"": 37178.57 ns per parse ""123456789"": 485.63 ns per parse As users expect Convert.ToXxx() to throw an exception when it fails, changing this is a bad idea I think. Possible solutions I can think of: - Extend the Convert class with Try-methods that don't throw exceptions, and use those while trying to parse an enum (much work) - Instead of checking whether the first character is a digit (https://github.com/Microsoft/referencesource/blob/master/mscorlib/system/enum.cs#L434), change that line to a TryParse of the whole string (the easier way) " 598 area-Meta Improve flow of readme The readme file contains several pieces of information, of which the list of components is the most substantial.

These extension methods largely work on top of the public surface of the `System.Type` class, although a few dealing with generic methods did resort to reflection in order to call internal methods to better detect and deal with ambiguities. I think that it would be very convenient to have these methods (or something like them) considered for addition into the core framework. I am willing and able to share my extension methods and could start a branch if there is traction to this idea. ### FindGenericInterfaces Identical to `Type.FindInterfaces` except that it will match on open generic interface types. ``` cs public delegate bool GenericTypeFilter(Type type, Type[] genericArguments, object filterCriteria); public static Type[] FindGenericInterfaces(this Type type, Type genericInterfaceType); public static Type[] FindGenericInterfaces(this Type type, Type genericInterfaceType, GenericTypeFilter filter, object filterCriteria); Type[] interfaces = typeof(int[]).FindGenericInterfaces(typeof(IEnumerable<>), (type, types, criteria) => types[0] == typeof(int), null); ``` ### ImplementsInterface Returns `true` if the type implements the specified interface. The interface can either be an open generic type or a closed constructed type. If the case of the former the overloads can be used to return the generic type arguments. For those overloads that accept a specific count of `out` parameters the generic type arguments must match the count of the `out Type` arguments. For the overload that accepts a `Type[]` the number of generic type arguments must match the length of the array. The overload that accepts an `out Type[]` will match any number of generic type arguments. _I also have `IsSubclassOf` and `Is` extension methods that function in almost the same manner except that the first matches if the type is a subclass of the specified type and the second matches if the type is a subclass of, implements or is of the specified type._ ``` cs public static bool ImplementsInterface(this Type type, Type interfaceType); public static bool ImplementsInterface(this Type type, Type interfaceType, out Type genericArgument); public static bool ImplementsInterface(this Type type, Type interfaceType, out Type genericArgument1, out Type genericArgument2); public static bool ImplementsInterface(this Type type, Type interfaceType, out Type genericArgument1, out Type genericArgument2, out Type genericArgument3); public static bool ImplementsInterface(this Type type, Type interfaceType, Type[] genericArguments); public static bool ImplementsInterface(this Type type, Type interfaceType, out Type[] genericArguments); Type elementType, keyType; if (typeof(int[]).ImplementsInterface(typeof(IEnumerable)) { ... } if (typeof(int[]).ImplementsInterface(typeof(IEnumerable<>), out elementType)) { ... } if (typeof(Dictionary).ImplementsInterface(typeof(IDictionary<>), out keyType, out elementType)) { ... } Type[] arguments = new Type[2]; if (typeof(Dictionary).ImplementsInterface(typeof(IDictionary<>), arguments)) { ... } arguments = null; if (typeof(Dictionary).ImplementsInterface(typeof(IDictionary<>), out arguments)) { ... } ``` ### GetGenericMethod _Separated into proposal [Add GetGenericMethod method to simplify finding generic methods via reflection](https://github.com/dotnet/corefx/issues/16567)._ Returns the generic method with the same number of specified generic arguments. The generic arguments are checked for compatibility with the generic type constraints. If a parameter type list is also specified then the parameter types must be acceptable for the given generic type arguments. _In order to properly handle matches and ambiguity resolution I did have to break out reflection in order to invoke the internal members `RuntimeType.FilterApplyMethodBase`, `DefaultBinder.FindMostDerivedNewSlotMeth` and `DefaultBinder.CompareMethodSigAndName`. A built-in implementation would not require to rely on any reflection._ ``` cs public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs); public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs, BindingFlags bindingAttrs); public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs, Type[] types); public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs, Type[] types, ParameterModifier[] modifiers); public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs, BindingFlags bindingAttrs, Binder binder, Type[] types, ParameterModifier[] modifiers); public static MethodInfo GetGenericMethod(this Type type, string name, Type[] genericArgs, BindingFlags bindingAttrs, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers); public class Foo { public void Bar(object value) { ... } public void Bar(T value) { ... } } MethodInfo genericBar = typeof(Foo).GetGenericMethod(""Bar"", new Type[] { typeof(string) }, new Type[] { typeof(string) }); ``` " 645 area-System.IO Support long file names on Windows Now would seem to be the time to finally tackle the MAX_PATH nightmare.

They create the need for rather redundant code, such as ``` Colors colorValue = (Colors) Enum.Parse(typeof(Colors), colorString); ``` which entails the need to add an additional cast, as well as instantiate a Type object that represents the enumeration type. It would be nice to add generic Parse overloads that correspond to the generic TryParse overloads: ``` public static TEnum Enum.Parse(String value); public static TEnum Enum.Parse(String value, Boolean ignoreCase); ``` Note that there's also another open issue on improving the performance of Enum.TryParse at https://github.com/dotnet/corefx/issues/594. 674 area-System.Diagnostics FileVersionInfo tests' native assemblies and exes do not have sources We should at least provide the sources for these native binaries so that we can tell what's going on if we hit issues.

Because we don't want to run the tests after a Visual Studio build (because VS has its own mechanisms for running tests), since #508 the BuildingInsideVisualStudio property is used to disable the RunTestsForProject target. Making the build system aware of the context in which its running in order to skip a target feels odd in a build system with a robust target and dependency mechanism. It seems to me that it would be more idiomatic for the build to expose its targets in such a way so that each context can use the target system to control what targets are run. In other words, do not include the RunTestsForProject in the dependency tree of the default target for the sub-project files (which is what Visual Studio will execute), but do include it in the dependency tree of the default target for the top-level build file. In practice, I believe this would just mean changing the default target for each sub-project to be Compile instead of Build. This would also have the positive effect of making the build IDE-agnostic, which is important as .NET Core becomes truly cross-platform. What would the value of the ""BuildingInsideVisualStudio"" property be from within Xamarin Studio, or SharpDevelop, or Sublime using [OmniSharp](http://www.omnisharp.net/)? Xamarin Studio actually sets BuildingInVisualStudio to true in order to try and increase compatibility, which is obviously not a desirable state of affairs. Let's try to reduce the need for such hacks by keeping the dependencies between the build and the IDE clean (i.e. one-way).

However, it throws exceptions, so it is too hard to implement behavior that matches simple explicit cast between integer types. As a solution - add TryXXX methods to Convert class. Additionally, it would be nice to have option to make Convert behave like explicit cast. For example, this is valid: ``` C# int a = -1; int b = (int)(uint)a; ``` But this is not: ``` C# int a = -1; int b = Convert.ToInt32(Convert.ToUInt32(a)); ``` This can be really useful when you process some data as ""just some bytes"" and you may get either signed or unsigned boxed value at input. As a possible solution - add overload that accepts second boolean argument and acts like an explicit integer cast.

" 692 area-System.Runtime Add a non-generic version of Enum.TryParse These are the methods in Enum class related to string parsing. ``` c# public static object Parse(Type enumType, string value); public static object Parse(Type enumType, string value, bool ignoreCase); public static bool TryParse(string value, out TEnum result) where TEnum : struct; public static bool TryParse(string value, bool ignoreCase, out TEnum result) where TEnum : struct; ``` Apparently Parse is exposed only in non-generic form, while TryParse is only exposed in generic form. This is somewhat inconsistent. It is simple enough to call a non-generic method in a generic method, but not the other way around. So Parse can be made generic using the following helper. But it is a lot harder to wrap TryParse into TryParse(Type enumType) without reflection calls. ``` c# public static TEnum Parse(string value, bool ignoreCase) { return Enum.Parse(typeof(TEnum), value, ignoreCase); } ``` The suggestion is to add a non-generic Enum.TryParse method, the API signature would look like ``` c# public static bool TryParse(Type enumType, string value, out object result) public static bool TryParse(Type enumType, string value, bool ignoreCase, out object result) ``` 693 area-System.Runtime Add Enum.SetFlag and Enum.RemoveFlag to make bitwise flagging easier To maintain multiple bool states in a class, instead of declaring many bool fields, an enum flag can be used to compact these states in to a single member to optimize for memory usage. ``` c# [Flags] enum DirtyFlags { X = 1, Y = 1 << 1, Z = 1 << 2 }; DirtyFlags dirtyFlags = DirtyFlags.X | DirtyFlags.Y | DirtyFlags.Z; ``` It is simple to test if a flag is set using `Enum.HasFlag(DirtyFlags.X)`, but the scenario is not complete. Without the ability to set and remove a flag, the following code needs to be maintained manually: ``` c# // Setting a flag dirtyFlags |= DirtyFlags.X; // Removing a flag, this is harder to remember :( dirtyFlags &= ^DirtyFlags.X; ``` The suggestion is to add 2 methods to Enum to help set and clear a flag. ``` c# public bool HasFlag(Enum flag); // This method already exists public bool SetFlag(Enum flag); public bool RemoveFlag(Enum flag); ``` These methods should be aggressively inlined since bitwise manipulations is very likely to be used in a performance sensitive scenario. 694 area-Meta State policy on mscorlib "I see a lot of confusion around mscorlib, since it's part of coreclr project, but it feels more like part of corefx.

SQL Server supports a native date-only type, and having a date-only type in .NET to match would be very handy. But not only from SQL: accepting an MVC action method parameter from an HTML5 input type=""date"" field would be simplified with a native Date type. Examples: ``` C# Date d = new Date(2015, 2, 9); Date d2 = Date.UtcToday; Date d3 = Date.LocalToday; // helper methods for adding/subtracting days, months, years, or TimeSpan Date d4 = d.AddDays(7); Date d5 = d.Subtract(TimeSpan.FromYears(2)); string s = d.ToString(); //--> ""2015-02-09"" // properties: int y = d.Year; int m = d.Month; int day = d.Day; DayOfWeek weekday = d.DayOfWeek; int doy = d.DayOfYear; // convert from DateTime: Date d6 = DateTime.UtcNow.ToDate(); Date d7 = (Date)DateTime.UtcNow; // convert to DateTime: DateTime dt = d.ToDateTime(); DateTime dt2 = (DateTime)d; // equivalent to new DateTime(d.Year, d.Month, d.Day) ``` " 701 area-Infrastructure Add Contract Reference Asssemblies to the repo We need to enabling building our contract reference assemblies in the CoreFX repo. They are be needed for a number of reasons: 1) We need to build them to put them in our nuget packages. 2) We need them to produce our facades for our nuget packages. 3) People would like to see a reference for what is supported (see #147 as example) and for what we will be bringing online overtime. We will need to figure out the structure we want to provide them in and provide the tooling for editing them. A strawman for the structure would be something like: src\System.Runtime\src\Contract\4.0.0.0\System.Runtime.cs|csproj src\System.Runtime\src\Contract\4.0.10.0\System.Runtime.cs|csproj src\System.Runtime\src\Contract\4.0.20.0\System.Runtime.cs|csproj 703 area-System.Globalization Open-source System.Globalization unit tests Note: The implementation of this contract lives in mscorlib in the [coreclr](https://github.com/dotnet/coreclr) repository, but we are planning to put tests in this repo and test against the NuGet package produced by the coreclr repo. 704 area-System.IO Open-source System.IO unit tests Note: The implementation of this contract lives in mscorlib in the [coreclr](https://github.com/dotnet/coreclr) repository, but we are planning to put tests in this repo and test against the NuGet package produced by the coreclr repo. 705 area-System.Reflection Open-source System.Reflection unit tests Note: The implementation of this contract lives in mscorlib in the [coreclr](https://github.com/dotnet/coreclr) repository, but we are planning to put tests in this repo and test against the NuGet package produced by the coreclr repo. 707 area-System.Threading Open-source System.Threading unit tests Note: The implementation of this contract lives in mscorlib in the [coreclr](https://github.com/dotnet/coreclr) repository, but we are planning to put tests in this repo and test against the NuGet package produced by the coreclr repo. 708 area-System.Text Open-source System.Text.Encoding unit tests Note: The implementation of this contract lives in mscorlib in the [coreclr](https://github.com/dotnet/coreclr) repository, but we are planning to put tests in this repo and test against the NuGet package produced by the coreclr repo. 709 area-System.Diagnostics Write a test for PROCESS_QUERY_LIMITED functionality "Per #303 we have some debt here we need to get tested.

VS needs the targets of project references to be in the scope of the current solution. While we could go and add this project everywhere, I think it will clutter the solutions. A better approach might be to use shared source files that we pull in the test targets/props. 746 area-Infrastructure The top-level src/ folder is cluttered with all of those .slns "IMHO, each library should have its sln file within its own folder. Instead of ``` src\ System.Xyz\ System.Xyz.sln ``` We should have ``` src\ System.Xyz\ System.Xyz.sln ``` I believe the reasons why we had the former originally are obsolete now. 1) We liked the idea of grouping related libraries together in a solution. Today, only System.Xml.\* does this. However, it will not really work long-term because we shouldn't have library-to-library project-to-project references as it messes with our package versioning story post-V1. 2) We had problems with redundant packages/ folders.

" 759 area-Infrastructure Incremental build tweaks Update Clean target to no longer delete PackagesDir, to address #529. Fixed an issue with the _RestoreBuildTools target where we sometimes get into a never ending running of that target in cases where your dir.props or pacakges.config is newer than the tools. This showed its head while I had edits to that file and was no longer cleaning my Packages directory. To address I always ensure the outputs are newer by touching them at the end of the target whenever it is ran. Also realized that our BuildPackages target was not being run any longer on clean builds and only on incremental builds. This showed that it is recently broken by the latest build tools update and I filed #758 for that but for now I'm disabling the building of the packaging. I also started importing dir.targets in build.proj so the tools were restored in time for them to be used in src\dir.proj even on clean builds. 765 area-Infrastructure Add daily build number to NuGet packages and fix package versioning. This is to address issue #758. This change adds BuildNumber.props containing the daily build number property that's consumed by the package build infrastructure. Updated package versions for Immutable and Metadata based on the values of the daily building packages. The values have a build number one greater than the last build. Deleted all nuspec files for non-shipping packages. 770 area-Infrastructure Make XunitTraitDiscoverers as a part of the custom Xunit. Inorder to skip tests and other xunit functionality, the projects require an extra project reference to XunitTraitDiscoverers. Making this a part of the netcore xunit will be good.

An attempt to address #679 This change adds a BuildAndTest and Test target to our default dir.targets file and hooks RunTestsForProject off the Test target so that by default if you build an individual project from the command line or in an IDE like VS it will just do the build and not run the tests. If people want to run the tests then they need to execute the BuildAndTest target (or just the Test target). This prevents the need for us to use special conditions like BuildingInsideVisualStudio in our targets. I've also changed the DefaultTargets for our build.proj and dirs.proj files to be BuildAndTest so if you run the build for them it will stil do the build and test run. cc @eatdrinksleepcode @nguerrera 800 area-Infrastructure Enable code coverage on VS2015 and include more libraries Two issues: 1) Code coverage doesn't work with VS2015. 2) Several of our libraries are disabled from code coverage. For the first, the issue turned out to be a failure of the OpenCover code coverage tool to read the PDBs produced by Roslyn. The library on which the tool depends for PDB reading has been updated to support Roslyn, and a more recent version of OpenCover than the one we're currently using pulls in that updated version of the PDB reader. As such, the fix is just to upgrade which version of OpenCover we use. For the second, whatever reason caused us to disable code coverage on several projects appear to have since been addressed, either by us or in the OpenCover update. The fix then is to just re-enable code coverage on these libraries. The only library that remains disabled for code coverage is System.Diagnostics.Process.dll. It's either hanging or just taking a really, really long time (PLINQ takes about 10 minutes, but at least it completes). Needs more investigation. 810 area-System.Globalization Implement System.Globalization.Extensions on Unix The library has been refactored to have the Unix implementation stubbed out. It needs to be properly implemented. 811 area-System.Diagnostics Implement System.Diagnostics.FileVersionInfo on Unix The library has been refactored to have the Unix implementation stubbed out. It should be implemented to the extent that makes sense on Unix. 817 area-System.IO Implement System.IO.FileSystem.Watcher for Mac The Linux implementation uses inotify, which is Linux-specific. We'll need a different implementation for Mac, such as one based on FAM, kqueue, or FSEvents. 818 area-Infrastructure Update solutions/projects with OS-specific configs For projects that have OS-specific implementations, this change modifies their solution and project files to create OS-specific configurations. Rather than just having a Debug or Release option, in Visual Studio a developer can now select OS_Debug or OS_Release, e.g. for a project that has a Windows implementation and a Unix implementation, Windows_Debug, Windows_Release, Unix_Debug, and Unix_Release will all be available options. Changing the configuration will update the properties used to configure conditional includes, build outputs, etc. cc: @mmitche, @AArnott.

While we've made `protected` members `public` in the past (such as `Exception.HResult`), this event was marked `virtual`, which while binary compatible, would be a source-breaking change for those that overrode it.

(It currently throws.) @ericstj: Can you help me figure out how to tweak FileStreamReadLightUp.cs to handle this? Also, @tmat has already mentioned to me that this code path will slow us down on Linux and Mac. Perhaps, this is the right opportunity to define a portable FileStream.Read overload that reads to unmanaged memory? 991 area-Infrastructure Enable code coverage report generation for individual projects If we run a subset of the projects for code coverage, we should still generate a report. 992 area-System.Numerics Consider saturated arithmetic functionality for Vector In the past, we've seen some requests for Vector to provide some means to do saturated arithmetic operations. Such operations could be useful for a variety of applications, like signal processing, image processing, etc. It makes sense to at least investigate what such functionality would look like, how it could be exposed, etc. Given that there are also SSE2+ instructions that expose some level of saturated arithmetic, I'm hopeful that we could also get some baseline hardware-instruction support for this. Work to do: - Define API surface exposed (which operations are supported) - Define which types support these operations (which integral types? all?) - Determine which operations could benefit from SIMD instructions - Create a simple working prototype (without hardware instructions) - Create formal API design speclet 993 area-System.Numerics Consider generic support for Shuffle and Shift operations on Vector Two useful operations that we have long-considered adding to Vector are shuffle and shift. These are pretty fundamental operations that low-level algorithms could very often take advantage of. One of the challenges was developing a generic but straightforward interface for utilizing such operations across all of the (integral) numeric types that Vector supports. Work to be done: - Define which operations are supported (shuffle at a minimum) - Determine which operations could benefit from SIMD instructions - These should be able to benefit greatly - Create a simple working prototype (without hardware instructions) - Create formal API design speclet and follow regular procedure 996 area-Infrastructure Dashboard: Add page to show test failures for specific area.

These applications are often already using primarily single precision floats for computations, and thus have to round trip through double to make use of these methods. I propose adding a FastMath or Mathf or similar set of methods for lower precision high performance implementations of these methods. If it were not for the existence of System.Numerics.Vectors, I would advocate that these simply be an external library separate from the core framework, but since the vector math library ships Quaternion and Matrix support, I would vastly prefer that these types make use of the faster math operations for things like calculating rotations. My reasoning is that these types exist in the first place for people concerned with performance, and as it stands they're simply too slow compared to the alternatives for them to see much use. For a practical anecdote, I recently wrote an OpenGL draw call stress test to determine CPU overhead and how many draw calls I can push from my .NET app. By far the biggest consumer of frame time was Sin and Cos inside the quaternion rotation method used to rotate the cubes I was rendering. Using a fully managed implementation of SinCos based on the venerable CEPHES library cut that time roughly in half. This could be further extended by vectorizing with SIMD, provided that the Vector types support a few more intrinsics such as shuffle. I wouldn't mind doing this work if people think it would be useful. My main concern is that shipping System.Numerics.Vectors (quaternions and matrices) without these faster math routines will forever doom them to obscurity, since switching to reduced precision operations in the future would be a breaking change. 1009 area-Infrastructure Error message in System.ServiceProcess.ServiceController when building from VS2015 DevCmd When building using Developer Command from VS 2015 I get following error message: (build doesn't fail though - jut red message) ``` NativeTestService.cpp cl : Command line error D8027: cannot execute 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\c1xx.dll' [E:\oss\corefx\src\System.ServiceProcess.ServiceController\tests\NativeTestService\NativeTestService.vcxproj] ``` It doesn't repro on VS 2013 DevCmd. 1010 area-System.Numerics Add support for extracting a bit mask from a Vector SSE2/AVX supports extracting the MSB from each 8 byte,4 byte,2 byte or 1 byte segment (the `movemask_*` family). This can be extremely useful while performing algorithms that are data sensitive and use SSE registers like big buffers. A user could implement algorithms that work entirely in safe code that could benefit from avoiding the allocation and rigmarole of copying data out of a register to an array when you just want to test if a field is not empty. Admittedly, it is a downer as ARM does not have an intrinsic for this operation but there is workarounds that should perform better than copying everything in and out memory to test the bytes. http://stackoverflow.com/questions/11870910/sse-mm-movemask-epi8-equivalent-method-for-arm-neon 1016 area-System.Xml Update the XElement implementation in System.Xml.XDocument to include XmlSchemaProvider attribute once the packages are refreshed. 1019 area-Meta Consider adding Disposables [Reactive Extensions](https://github.com/Reactive-Extensions/Rx.NET/tree/master/Rx.NET/Source/System.Reactive.Core/Reactive/Disposables) and [System.Threading.Tasks.Dataflow](https://github.com/dotnet/corefx/blob/master/src/System.Threading.Tasks.Dataflow/src/Internal/ActionOnDispose.cs) are using their own internal Disposables.

Those names can be used in an indexer of `RegexGroupCollection`, however the `RegexGroup` objects themselves do not provide a `Name` property. The names can be retrieved using `regex.GetGroupNames`, but it is not immediately obvious -- and I'm not sure it is even possible if static `Regex` method was used for matching. To prove it is not obvious, see this [Regex: get the name of captured groups in C#](http://stackoverflow.com/questions/1381097/regex-get-the-name-of-captured-groups-in-c-sharp) which at the moment had 48 votes on question, and 66 on answer.

Includes tests for File, Directory, FileInfo, and DirectoryInfo. A few tests have been rewritten in the xunit style, but the majority of these tests have been ported from ToF, which were ported from old tree. When porting, I modified or disabled tests to make sure every test only writes in its working directory. I verified this with PerfView. I also replaced hard-coded paths with calls to Path.GetRandomFileName() to prevent multiple runs from interfering with each other, and multiple tests running in parallel from interfering with each other. Any test that used a delay to wait for the state of the file system to stabilize was marked with OuterLoopAttribute. On my machine, all of the tests including OuterLoop take between 10s and 15s to run. Just inner loop tests take between 1s and 2s to run. Lots of these tests are candidates for rewriting, and Eric introduced a useful base class for tests when he rewrote the FileStream tests. Checking in these ported assets will give us a good idea of what the coverage is, and act as a baseline to compare the rewritten tests against. 1053 area-System.ComponentModel Make DisplayNameAttribute available in .NET Core This was originally going to be a request to move `DisplayNameAttribute` into Core, but the problem seems a little bigger than that. Currently, `System.dll` houses approximately a couple hundred types spread across four dozen different namespaces, but not everything in it is listed on the [Open Source Progress table](https://github.com/dotnet/corefx-progress/blob/master/src-diff/README.md) (although a select few namespaces like `System.Security.Cryptography.X509Certificates` _are_ there). This still makes some namespaces (for example `System.ComponentModel`) feel incomplete because of how they're spread across different assemblies. The previously mentioned `X509Certificates` namespace is already being tracked with all its types from `System.dll`, so other namespaces should follow suit, right? I was porting a project of mine over to see the ASP.NET vNext templates in action, but the lack of `DisplayNameAttribute` is literally the only thing preventing me from building it (even if I tell it to not target .NET Core) without commenting those attributes out. And if .NET Core's philosophy is to only use what you need, why should I be forced to import some monolithic DLL with hundreds of types that I don't need just for the one that I _do_ need, because that type is not in the DLL named after its containing namespace? ¯\(°_o)/¯ 1054 area-Infrastructure Add NuGet.org and MyGet.org latest build feeds to readme.md The CoreFX NuGet.org and MyGet.org latest build / package feeds should be added to our README.md.

As example consider #972. Commits like `Merge branch 'master' into Issue587` (aaa5434) clutter history and should be avoided. `git rebase` should be used for updating branch with fix. Other commits in this PR could be squashed. As another example consider PR #1003. It's initial commit of the library so it's OK to address feedback in a separate commit. However in this PR feedback addressed twice and the second could be amended to the first. Conclusion: 1. Merge conflicts should be resolved through rebasing. 2. PR feedback should be in a separate commit if it contains important changes. Changes like formatting or renaming variable introduced in PR are not important and could be addressed through amending/rebasing. " 1068 area-System.Reflection Allow ISignatureTypeProvider to be a struct The `SignatureDecoder` takes the provider as a naked interface. This makes it inefficient to bake it by a struct because it will cause it being boxed each time it's passed. However, it's very desirable to make the provider a struct because it allows the caller to provide call site specific information. For example, in order for implementers to reference the generic type parameters of the method or type, the `ISignatureTypeProvider` needs to have access to the containing type / containing method. To avoid the boxing operation, the methods simply needs an additional contraint like so: ``` csharp public static TType DecodeType(Handle handle, TProvider provider) where TProvider : ISignatureTypeProvider ``` Unfortunately, this causes some noise as C# is no longer able to infer the type arguments, so each call site must now qualify the type arguments. 1071 area-System.Reflection Merge master to dev/metadata In particular, the changes from PR #1026 are needed to address the CI failure in #1068.

However it suffers from a couple of issue: - Accessing MainModule of 64 bit process from a 32 bit one throws an exception - You can't access MainModule of elevated process from a non elevated one As you can see many developers [encounter](http://stackoverflow.com/q/8431298/239438) [these](http://stackoverflow.com/q/9501771/239438) issues. I suggest adding a new property which returns the path to executable of the Process.

From my own experience most of people use `Path` when asking question on stackoverflow but @Priya91 suggested calling it `MainModuleFilePath` as it is returning Path of the `MainModule` property. ## Cross Platform Support To implement this property on other platforms on Linux we can use `readlink` to read the value of `""/proc/%d/exe""` symlink and on OS X we can use `proc_pidpath` which returns process path given process pid." 1085 area-System.Reflection MetadataReader: (THandle)(Handle)default(THandle) should round-trip for all handles For most handles default(THandle) is the canonical nil value that can convert to the weakly-typed Handle and back, but for some such as StringHandle and NamespaceHandle default(THandle) is an invalid value that becomes a nil module handle on conversion to Handle and cannot be round-tripped back to THandle.

IE, is that Int32 seconds or milliseconds? Or maybe minutes? I've been fixing my team's source code to use the unit-agnostic TimeSpan class wherever possible. However the .NET Framework is not complete in its adoption of TimeSpan. Specifically, we don't have a Process.WaitForExit overload that takes a TimeSpan, only an Int32 for the timeout. I suggest someone look through all .NET Framework API's for Int32 parameters containing ""second"", ""millisecond"", ""ms"", ""timeout"" (and perhaps ""time"") and see if there is a parallel TimeSpan-based overload.

This issues comes about as a result of the following question on Stack Overflow: http://stackoverflow.com/questions/28947090/culture-and-linq-to-xml There appears to be no way to customize how a custom object is serialized to XML. The main problem this causes in my code is related to culture, but this could apply to other areas too. Looking at the code, it seems that there is no customization point for an object passed as content to LINQ to XML. Is this correct?

It should be trivial to add support for Math.Exp and in fact I've done this with my local copy of System.Numerics.Vectors using SquareRoot as a guiding example. My application now uses the new Vector.Exp function instead of me having to use the CopyTo function to unpack my Vector to a double[] array, perform Math.Exp on each element of the array and then pack up into a new Vector.

Single-precision floating-point support should be provided for these mathematical functions in order to better interop with high-performance, scientific, and multimedia-based applications where single-precision floating-points are the only implementation required and/or used. Since adding these methods to the existing `System.Math` class would break backwards compatibility, they should be provided through a separate class that provides the same and/or similar functionality. Providing these new APIs would: - improve code readability (especially in the non-hardware backed implementations of methods in the `System.Numerics.Vector` structs) - improve code performance in areas where the single-precision implementation is all that is required - provide better interoperability with high-performance, scientific, and multimedia-based applications where data structures and existing code may be dependent on single-precision implementations of such methods. - provide a more advanced infrastructure for mathematics in the CoreCLR ### Proposed API The proposed API here provides feature-parity with the existing double-precision math functions provided by the framework. #### System.BitConverter ``` C# public static class BitConverter { public static float Int32BitsToSingle(int); public static int SingleToInt32Bits(float); } ``` #### System.Single ``` C# public static partial class MathF { public const float E = 2.71828183f; public const float PI = 3.14159265f; // Trigonometric Functions public static float Acos(float); public static float Asin(float); public static float Atan(float); public static float Atan2(float, float); public static float Cos(float); public static float Sin(float); public static float Tan(float); // Hyperbolic Functions public static float Cosh(float); public static float Sinh(float); public static float Tanh(float); // Exponential Functions public static float Exp(float); // Logarithmic Functions public static float Log(float); public static float Log(float, float); public static float Log10(float); // Power Functions public static float Pow(float, float); public static float Sqrt(float); // Rounding Functions public static float Ceiling(float); public static float Floor(float); public static float Round(float); public static float Round(float, int); public static float Round(float, int, MidpointRounding); public static float Round(float, MidpointRounding); public static float Truncate(float); // Manipulation Functions public static int Sign(float); // Minimum, Maximum, and Difference Functions public static float Max(float, float); public static float Min(float, float); // Other Functions public static float Abs(float); public static float IEEERemainder(float, float); } ``` ### Example Usage Currently to calculate the Tangent for each member of the `System.Numerics.Vector4` struct, you currently have to call the double-precision version of the method and cast to the result to a single-precision value: ``` C# public static Vector4 Acos(Vector4 value) { return new Vector4((float)(Math.Acos(value.X)), (float)(Math.Acos(value.Y)), (float)(Math.Acos(value.Z)), (float)(Math.Acos(value.W))); } ``` With the proposed changes, this would now be simplified to the following: ``` C# public static Vector4 Acos(Vector4 value) { return new Vector4(Mathf.Acos(value.X), Mathf.Acos(value.Y), Mathf.Acos(value.Z), Mathf.Acos(value.W)); } ``` The `System.Numerics` library itself is filled with similar examples as are various bits of code in the CoreFX and CoreCLR repositories. ### Perf Numbers All performance tests are implemented as follows: - 100,000 iterations are executed - The time of all iterations are aggregated to compute the `Total Time` - The time of all iterations are averaged to compute the `Average Time` - A single iteration executes some simple operation, using the function under test, 5000 times The execution time below is the `Total Time` for all 100,000 iterations, measured in seconds. **Hardware: Desktop w/ 3.7GHz Quad-Core A10-7850K (AMD) and 16GB RAM** | Function | Improvment | Execution Time - Double | Execution Time - Single | | :-: | :-: | :-: | :-: | | Abs | 0.199243555% | 0.63752649s | 0.63625626s | | Acos | 12.30220910% | 11.5265412s | 10.1085220s | | Asin | 18.66801808% | 11.9472425s | 9.71692911s | | Atan | 21.10350002% | 10.9964683s | 8.67582861s | | Atan2 | 20.51327307% | 24.3328097s | 19.3413540s | | Ceiling | 12.91487191% | 1.87116459s | 1.62950608s | | Cos | 5.026665542% | 7.19916547s | 6.83728750s | | Cosh | 16.46166555% | 13.5416170s | 11.3124413s | | Exp | 33.67586387% | 6.65578424s | 4.41439140s | | Floor | 10.39208688% | 1.74655247s | 1.56504922s | | Log | 19.81117664% | 6.42244806s | 5.15008553s | | Log10 | 18.40605725% | 6.75118866s | 5.50856101s | | Pow | 47.85595440% | 31.8820155s | 16.6245727s | | Round | 0.976398142% | 4.22620632s | 4.18494172s | | Sin | 15.49539339% | 5.98022268s | 5.05356365s | | Sinh | 17.96609899% | 14.6242270s | 11.9968239s | | Sqrt | 4.676516651% | 2.51281945s | 2.39530703s | | Tan | 30.33470555% | 9.07290178s | 6.32066374s | | Tanh | 0.108182099% | 8.12724112s | 8.11844890s | I believe some extra perf will be squeezed out when the intrinsics (such as `CORINFO_INTRINSIC_Sqrt`) are properly implemented in the VM layer for single-precision values. Without such functionality, it falls back to the double-precision functionality (extra precision, reduced performance) for certain calls. ### Pull Request There is a sample pull request covering these changes available: dotnet/coreclr#5492 ### Additional Details This will require several changes in the CoreCLR as well to support the new APIs via FCALLs and Intrinsics. 1153 area-System.Console Bring back Console.ReadKey() For reference, see issue #311 and the related aspnet/Hosting#140. Console.ReadKey() can solve both issues (thought explicit support for CancelKeyPress is nice as that can handle different keyboard configurations etc). ReadKey() is a helpful API for many console app scenarios and is quite difficult for users to implement in a non-Windows-specific way if they want to get the same functionality. Please consider bringing it back. 1155 area-System.Linq Ordering of ParallelEnumerable.GroupJoin and Join "This feels strange or bug-ish to me, but I'm not seeing anything either way in documentation. The following: ```c# ParallelQuery left = Enumerable.Range(1, 4).AsParallel().AsOrdered(); ParallelQuery right = Enumerable.Range(8, 32).AsParallel().AsOrdered(); foreach (Tuple> p in left.GroupJoin(right, x => x, y => y / 8, (k, g) => Tuple.Create(k, g))) { Console.Write(p.Item1.ToString() + "":""); foreach (int i in p.Item2) { Console.Write(i.ToString() + "",""); } Console.WriteLine(); } Console.Read(); ``` ... has output like this: ![groupjoin](https://cloud.githubusercontent.com/assets/5569508/6683955/d5efffe4-cccf-11e4-8958-4dfde0993f1d.jpg) The first grouping is out of order, whereas I'm expecting even the grouped elements to be returned in order (which is what the non-parallel version does). Strangely, of the multiple times I've run it, only the first run has ever been out of order. Using `OrderBy` on the right query tends to result in other runs being disordered.... `Join` has similar problems to `GroupJoin`: ```c# ParallelQuery left = Enumerable.Range(1, 4).AsParallel().AsOrdered(); ParallelQuery right = Enumerable.Range(8, 32).AsParallel().AsOrdered(); int prev = 0; foreach (Tuple p in left.Join(right, x => x, y => y / 8, (k, g) => Tuple.Create(k, g))) { if (prev != p.Item1) { Console.WriteLine(); Console.Write(p.Item1.ToString() + "":""); prev = p.Item1; } Console.Write(p.Item2.ToString() + "",""); } Console.Read(); ``` ... is producing output that looks like this: ![join](https://cloud.githubusercontent.com/assets/5569508/6684267/ee062632-ccd2-11e4-8363-679f7ed8dd0b.png) ...where every run is disordered. This is the behavior of the current consumer release as well. So is this ""intended"" behavior, and the documentation should be updated to warn people about the change from the sequential version (which explicitly states the ordering of the child elements is preserved), or is this an actual bug? @stephentoub , @svick , any thoughts?

There are a whole bunch of instructions available to do this, so we'd like to expose a coherent subset of these via Vector. ## Rationale and Usage Simple stream processing, such as the operations already supported on Vector, are entirely parallel and thus don't benefit from shuffling operations. However, lots of common uses of SIMD do require it, such as doing geometric vector operations like matrix multiplies and vector cross products. These are key scenarios for certain users, such as game developers. If rearranging elements is required for an algorithm and fast hardware support is not provided, the cost of loading and storing to and from SIMD registers might exceed any benefits gained from using SIMD in the first place. When looking at existing libraries that wrap SIMD functionality at a low level, it's apparent that there are a few main use cases of shuffle: - Permuting the elements of two different vectors into a result - ""Swizzling"" the elements within a single vector - ""Splatting"" or ""broadcasting"" one element to all others within a single vector Rather than expose one single shuffle method directly, I think it makes sense to go with this slightly higher level functionality such that the API doesn't become too tied to a particular architecture's instruction set. ## Proposed API New methods on the Vector struct: ``` csharp // pick elements from a and b to place into result internal static unsafe Vector Permute2 (Vector a, Vector b, int s0, int s1); internal static unsafe Vector Permute4 (Vector a, Vector b, int s0, int s1, int s2, int s3); // rearrange elements within a internal static unsafe Vector Swizzle2 (Vector a, int s0, int s1); internal static unsafe Vector Swizzle4 (Vector a, int s0, int s1, int s2, int s3); // rearrange bytes in a internal static unsafe Vector ShuffleBytes (Vector a, Vector mask); // broadcast specified element to all other elements in a internal static unsafe Vector Splat (Vector a, int element); ``` New methods on Vector class that are simple wrappers around the Vector methods. ``` csharp public static Vector Permute (Vector a, Vector b, int s0, int s1); public static Vector Permute (Vector a, Vector b, int s0, int s1); public static Vector Permute (Vector a, Vector b, int s0, int s1); public static Vector Permute (Vector a, Vector b, int s0, int s1, int s2, int s3); public static Vector Permute (Vector a, Vector b, int s0, int s1, int s2, int s3); public static Vector Permute (Vector a, Vector b, int s0, int s1, int s2, int s3); public static Vector Swizzle (Vector a, int s0, int s1); public static Vector Swizzle (Vector a, int s0, int s1); public static Vector Swizzle (Vector a, int s0, int s1); public static Vector Swizzle (Vector a, int s0, int s1, int s2, int s3); public static Vector Swizzle (Vector a, int s0, int s1, int s2, int s3); public static Vector Swizzle (Vector a, int s0, int s1, int s2, int s3); public static Vector ShuffleBytes (Vector a, Vector mask); public static Vector Splat (Vector a, int element); ``` ## Details and Questions - There are a lot of tradeoffs when picking method signatures for shuffle. For example, instead of taking many selector parameters, we could instead have one combined integer mask. However, pretty much every single caller will then implement their own helper method to do the bitwise combination of the mask, so all callsites get more complicated. Additionally, we want the JIT to discover and optimize the cases where the parameters are JIT-time constants. - I chose for the selector parameters to be ints instead of, say, bytes. I'm not sure if there's a compelling reason to choose one over the other. In either case, we'd have to define what happens when the parameters are out of range. Since the intrinsics are going to bitwise combine them, in the interests of speed it'd be good if they could say that are not range checked. - We could also have a Permute8 and Swizzle8 and extend the methods to shorts and ushorts. The parameter lists get kind of unwieldy... - ShuffleBytes is an interesting case. pshufb is a very useful instruction to expose, but it's an SSSE3 instruction. It may be worth being more explicit about which features are supported by the hardware via some set of caps flags instead of the single boolean IsHardwareAccelerated we have now. - Shuffle intrinsically breaks the abstraction of Vector of not needing to know the underlying register size. Honestly, I think that's an unworkable abstraction in the long term; it's too difficult to write usage code that can work with arbitrarily sized vectors, so it might be worth exploring having specifically sized Vector128, Vector256, etc. This is clearly a discussion to be had in a separate issue though. " 1170 area-System.Collections IEnumerator.Current does not throw after hitting the end of the collection. This issue is in the `List.Enumerator` class. When the collection is enumerated to then end and then modified, accessing `IEnumerator.Current` returns `default(T)` rather than throwing. According to the [documentation](https://msdn.microsoft.com/en-us/library/vstudio/system.collections.ienumerator.current%28v=vs.100%29.aspx) it should throw. Simple Test case: ``` CSharp var list = new List{0,1}; var enumerator = ((IEnumerable)list).GetEnumerator(); while (enumerator.MoveNext()){} list.Add(2); Assert.Throws(() => enumerator.Current); ``` This test fails currently with `enumerator.Current` returning 0. 1171 area-System.Collections Add tests for KeyedCollection.

I will be bringing over tests for `IList`, `ICollection`, and `IEnumerable` in a future PR. " 1178 area-System.Linq Add System.Linq.Expressions source and tests. 1182 area-System.Linq System.Linq performance improvement suggestions "With Linq-to-Objects it is quite common practice to perform a series of transformations, and then materialize sequence to a concrete collection type by calling _ToArray(), ToList(), ToDictionary()_. These operations would work much faster if they knew the number of elements in the sequence. Currently System.Linq.Enumerable has special treatment for _ICollection_ interface only. I suppose that additional support for _IReadOnlyCollection_ can improve performance in some cases, because through it we can figure out the total number of elements. Another problem with System.Linq is that in many cases the information about the number of elements is lost. One of the most common example: ``` C# List source = ...; List transformed = source.Select(o => o + 1).ToList(); ``` Obviously _Select_ does not change the number of elements in the sequence, but _ToList_ method cannot take advantage of that. Information is lost. In this particular scenario, it would be great for _Select_ to return some _SelectIterator_ instance, which implements _IReadOnlyCollection_, and thereby passes the number of elements to the subsequent methods. **Steps to measure performance gain**: 1. Find in _System.Linq.Tests\Performance_ the test for the method you've changed; 2. Uncomment `[Fact]` attribute above that method; 3. Build test project by Visual Studio in Release mode; 4. Go to the folder with tests binaries: `bin\tests\Windows_NT.AnyCPU.Release\System.Linq.Tests\aspnetcore50\`; 5. Open command prompt (cmd.exe or PowerShell); 6. Run command: `CoreRun.exe xunit.console.netcore.exe System.Linq.Tests.dll -parallel none -trait ""Perf=true""`; 7. Wait for results that will be printed right in the command window; 8. Don't forget to run tests with different collection sizes. This can be done by varying _elementCount_ argument of _Measure_ method. **Casting to `IReadOnlyCollection`** is a slow operation so it is not a good idea to check if this interface implemented. The performance drop will be most noticeable on the small collections. **Tasks**: - [ ] `Select`: add iterators for `List`, `Array[T]`, `ICollection`; - [ ] `ToArray`, `ToDictionary`: add special support for `ICollection` (and, very carefully, for `IReadOnlyCollection`) to get the initial capacity; - [ ] `ToList` (???): add special support for `IReadOnlyCollection` to get the initial capacity (separated as it will affect _System.Collections.Generic_); - [ ] `OrderBy(Descending)/ThanBy(Descending)`: implement special iterator for `ICollection` to propagate `Count`; - [ ] `Cast`, `Reverse`: add iterators for `ICollection` to propagate `Count`; - [ ] `Range`, `Repeat`: add an iterator that implements `ICollection`; - [ ] `Skip`, `Take`: add an iterator that handle `ICollection`; - [x] Add performance tests for _System.Linq_ " 1187 area-System.Collections Improve the exception message of ToDictionary when keys are duplicated "`Enumerable.ToDictionary` makes it easy to turn an array into a dictionary. But when the keys are duplicated in the source array, it just throws an `ArgumentException` that says **An entry with the same key already exists**. It is hard to know what keys are duplicated. To improve the exception message without adding extra overhead, the exception message can be modified to **$""An entry with the key { key } already exists""**. `ToDictionary` internally calls `Dictionary.Add()`, so the improvement made to Dictionary.Add benefits all code that calls the method.

It is fairly common scenario where you have user inserted data that has some kind of place-holders (tokens), that later have to be replaced by some templating system. Current solutions in the internet involve using regex class for this trivial task. ```c# var userTemplateData = ""Hello there. Time now is %currenttime%""; var evaluatedData = Regex.Replace( userTemplateData, ""%CurrentTime%"", DateTime.Now.ToString(), RegexOptions.IgnoreCase); // evaluatedData = ""Hello there. Time now is 01/04/2015 14:37""; ``` This approach is horrible: 1) not readable 2) often times not correct, as pattern has to be run through `Regex.Escape` before. 3) most likely slow(er) After the necessary change is added, we can do: ```c# var evaluatedData = userTemplateData.Replace( ""%CurrentTime%"", DateTime.Now.ToString(), StringComparison.InvariantCultureIgnoreCase); ``` How common would the usage of this be? I would **speculate** that every programmer in their career will hit the lack of case-insensitive replacement in framework at least once. I can't say much more, expect provide some StackOverflow links below in Details section. I did quick search through the code-base I am new to, and found around ~30 case-insensitive `Regex.Replace` usages. # Proposed API ```c# public sealed class String : ... { .... // these two methods are provided for framework consistency // trying to follow the StartsWith/EndsWith public string Replace(string oldValue, string newValue, StringComparison comparison); public string Replace(string oldValue, string newValue, bool ignoreCase, CultureInfo culture); public string Replace(char oldValue, char newValue, CompareOptions options); .... } ``` # Details Namespace: **System** Type: **System.String** Assembly: **System.Runtime.dll** I'd love to see the current `string.Replace` [CoreClr implementation](https://github.com/dotnet/coreclr/blob/cbf46fb0b6a0b209ed1caf4a680910b383e68cba/src/classlibnative/bcltype/stringnative.cpp#L835) pulled out from CoreClr, and implemented 100% in the `String.cs`: This would help to: - avoid code-duplication - make it more transparent (programmers can take look at the implementation) - unit-test a little less, as they share both common functionality for `Replace(..., StringComparison.Ordinal);` Alternatively, we could also modify the existing `CoreClr` implementation to deal with `StringComparison`. Or, just rewrite everything from zero. # Links to explore http://stackoverflow.com/questions/244531/is-there-an-alternative-to-string-replace-that-is-case-insensitive http://stackoverflow.com/questions/6275980/string-replace-by-ignoring-case http://weblogs.asp.net/jongalloway/71188 # Updates - Edited this description to make it more of a **speclet**, based on the discussion below and the proposed API Review process. - Feedback to @tarekgh.

It supports the ZIP and gzip archive formats and the Deflate compression algorithm. **_Testing**_ System.IO.Compression has existing test assets that fit three categories: 1. Round trip data through compression and verify it remains intact 2. Extract and verify data compressed through other compatible compression libraries 3. Verify behavior when attempting to decompress invalid or edge case archives The existing assets include archives, as well as decompressed binary files both for use as source material, and an oracle to verify decompression. Altogether, the binary assets weigh in at about 40MB. **Problem:** these test assets need to exist at test run time. Placing them in our corefx git repository is problematic because binary assets do not compress well and will bloat the size of our repository. **Proposal:** Binary test assets are packaged in to a nuget package per test assembly to be deployed at test run time. The binary assets to generate these nuget package are persisted in a single separate Git repository. Git repository structure: corefx-testdata\ corefx-testdata\System.IO.Compression.TestData.nuspec corefx-testdata\System.IO.Compression.TestData\ Nupkg structure: content\ Test asset nuget packages are depended on by the test assembly’s packages.config Currently, nuget is designed to deploy at package reference time (ie. when a package is referenced in Visual Studio) rather than runtime. In Dev14 this is changing. Until then, we’ll include a target in the test assembly’s csproj to copy the assets from the downloaded nuget package to the test’s working directory. In addition to System.IO.Compression, metadata reader uses binary test assets, but as they are only 100KB combined and are not a practical problem. System.IO.Packaging has 60GB of test assets. **Proposal:** System.IO.Packaging split their test assets in to tiers, with a single nuget package per tier. The inner loop tests should be no more than some number of megabytes. **_Native Dependencies**_ In the desktop .NET Framework, although we have a purely managed implementation of the deflate algorithm, customers have reported that the popular cross-platform open-source zlib library is faster and performs high quality compression. In response we include zlib, which we wrap and delegate to. We build it from source using the unmodified 1.2.3 version of the sources in the FX partition, and name the resulting output “clrcompression.dll.” On Windows, to fit with .NET Core’s app-local, side-by-side model, if we include zlib, we should deploy a copy of the native assembly alongside the managed System.IO.Compression.dll assembly included with an application. zlib distributes both sources and official binaries. While we could redistribute the official zlib binary, unfortunately they only release a 32-bit version and we are currently distributing a 64-bit version of coreclr. While zlib has a permissive license, it is not the MIT license, and including it in the corefx repository would mean the corefx repository no longer only contained code under a single license. **Proposal:** Continue building clrcompression.dll from the FX repository. Publish the 64-bit version of clrcompression.dll in a nuget package System.IO.Compression.clrcompression-x64.nupkg. Make System.IO.Compression.clrcompression-x64 a dependency of the System.IO.Compression package. **X-Plat todo:** Linux has a strong history of deploying applications and their dependencies through package managers. Packagers bundle the application binaries and metadata describing dependencies in to packages, and publish those on package manager repositories. We are planning to declare other framework and runtime dependencies through package managers where appropriate, and System.IO.Compression’s zlib dependency should be consistent. " 1305 area-System.Xml Inconsistent behavior of XmlAttributeCollection.InsertBefore and InsertAfter "I've noticed an inconsistent behavior of `XmlAttributeCollection.InsertAfter(XmlAttribute newNode, XmlAttribute refNode)` comparing to `InsertBefore` when the reference node is the last in the collection (the first for `InsertBefore`) and it's a duplicate of the new node. The duplicate node (attribute) needs to be removed before inserting. `InsertAfter` is unable to handle the case and throws `System.ArgumentOutOfRangeException` further in `List.Insert()` due to an incorrectly calculated insert position, while `InsertBefore` does the job. I'm not sure if this case has any practical use, but might be worth fixing. The following unit test reproduces the problem: ``` [Fact] // [ActiveIssue(""Throws argument out of range exception"")] public void InsertAfterRemovesDupRefAttr() { const string attributeName = ""existingAttr""; const string attributeUri = ""some:existingUri""; XmlDocument doc = CreateDocumentWithElement(); XmlElement element = doc.DocumentElement; element.Attributes.Append(doc.CreateAttribute(""attr1"", ""some:uri1"")); element.Attributes.Append(doc.CreateAttribute(""attr2"", ""some:uri2"")); XmlAttribute refAttr = element.Attributes.Append(doc.CreateAttribute(attributeName, attributeUri)); //dup XmlAttribute newAttr = doc.CreateAttribute(attributeName, attributeUri); XmlAttributeCollection target = element.Attributes; target.InsertAfter(newAttr, refAttr); // throws // Assert... } ``` A similar case (the reference attribute is the first in the collection) works for `InsertBefore`: ``` [Fact] public void InsertBeforeRemovesDupRefAttr() { const string attributeName = ""existingAttr""; const string attributeUri = ""some:existingUri""; XmlDocument doc = CreateDocumentWithElement(); XmlElement element = doc.DocumentElement; XmlAttribute refAttr = element.Attributes.Append(doc.CreateAttribute(attributeName, attributeUri)); //dup element.Attributes.Append(doc.CreateAttribute(""attr1"", ""some:uri1"")); element.Attributes.Append(doc.CreateAttribute(""attr2"", ""some:uri2"")); XmlAttribute newAttr = doc.CreateAttribute(attributeName, attributeUri); XmlAttributeCollection target = element.Attributes; target.InsertBefore(newAttr, refAttr); // Assert... } ``` " 1313 area-System.IO FileInfo: get_LastWritTime test fail ``` EXEC : warning : (runTest, d:\corefx\src\System.IO.FileSystem\tests\FileInfo\get_LastWriteTime.cs, 100) Eror_f984f!

"Parallel.Linq.Distinct doen't return the first ""equal"" element in ordered queries. Take, for example, the following set: `{0, 1, 2, 3, 4, 5, 6, 7}` - and use a comparator that says everything `mod 4` is identical (so, `0` is the same as `4`, `1` and `5`, etc). I'm somewhat expecting to get `{0, 1, 2, 3}`, but I don't - any of the 'later' identical values can be returned. For those of you contending that ""They're identical, it doesn't matter"", which I somewhat thought too, I'm basing this on comments internal to the [Distinct operator](https://github.com/dotnet/corefx/blob/master/src/System.Linq.Parallel/src/System/Linq/Parallel/QueryOperators/Unary/DistinctQueryOperator.cs#L238-L251): ``` 238 // For each element, we track the smallest order key for that element that we saw so far 239 TKey oldEntry; 240 241 Wrapper wrappedElem = new Wrapper((TInputOutput)elem.First); 242 243 // If this is the first occurrence of this element, or the order key is lower than all keys we saw previously, 244 // update the order key for this element. 245 if (!_hashLookup.TryGetValue(wrappedElem, out oldEntry) || _keyComparer.Compare(orderKey, oldEntry) < 0) 246 { 247 // For each ""elem"" value, we store the smallest key, and the element value that had that key. 248 // Note that even though two element values are ""equal"" according to the EqualityComparer, 249 // we still cannot choose arbitrarily which of the two to yield. 250 _hashLookup[wrappedElem] = orderKey; 251 } ``` The [ordering page](https://msdn.microsoft.com/en-us/library/vstudio/dd460677%28v=vs.110%29.aspx) just says these operators return ""ordered"" results given an ordered source, which is technically still happening - so long as there was an element in that original position, that or an equal one is returned in that position. Vanilla LINQ actually says `Distinct` returns _unordered_ results, but I'm guessing they really meant ""we didn't use `OrderBy` to make things easier for us"", especially as all the examples (and the way the operator is implemented) show that it retains the ordering of the original source (and how the other set operators behave - `Except` doesn't mention ordering, `Intersect` explicitly mentions the original order is retained, and `Union` mostly implies the original order is retained). So... which is correct? Should the actual-first equal element be returned (as I'm expecting), or that's a stronger guarantee than we need (and any equal item can be returned in its place)? Example reproduction code (may fail to fail): ``` using System; using System.Collections.Generic; using System.Linq; using Xunit; namespace Test { public class Example { [Fact] public static void DistinctExample() { ParallelQuery original = ParallelEnumerable.Range(0, 24).AsOrdered(); int seen = 0; Assert.All(original.Distinct(new ModularCongruenceComparer(4)), i => Assert.Equal(seen++, i)); Assert.Equal(4, seen); } private class ModularCongruenceComparer : IEqualityComparer { private int _mod; public ModularCongruenceComparer(int mod) { _mod = Math.Max(1, mod); } private int leastPositiveResidue(int x) { return ((x % _mod) + _mod) % _mod; } public bool Equals(int x, int y) { return leastPositiveResidue(x) == leastPositiveResidue(y); } public int GetHashCode(int x) { return leastPositiveResidue(x).GetHashCode(); } public int GetHashCode(object obj) { return GetHashCode((int)obj); } } } } ``` " 1332 area-System.Linq Parallel.Linq.Concat not consistent with ordered input "`Parallel.Linq.Concat` isn't behaving consistently when given ordered input sources. As `Concat` is a binary operator, two sources may be supplied. The inconsistency surfaces depending on which, and how, operand is ordered. If both **or** either (only the left or the right) is ordered via `AsOrdered()`, the entire output is ordered. If the left operator is ordered via any of the `OrderBy(...)` operators (`OrderBy`, `OrderByDescending`, `ThenBy`, `ThenByDescending`), the entire output is ordered. If the _right_ operator is ordered via any of the `OrderBy(...)` operators, only the _left_ output is ordered (as by `AsOrdered()`), and the right is returned in a non-deterministic order. It only seems to do this with right sources constructed via `Enumerable.Range(...).AsParallel()` and `Partitioner.Create(...).AsParallel()`. Using a `List` is safe (eg, `Enumerable.Range(...).ToList().AsParallel()`), however the output of LINQ is not: `list.Select(x => x).AsParallel()` can return unordered output. How the left operand is constructed appears to have no effect. This is also the behavior of the current consumer release. Example program: ``` static void Main(string[] args) { int leftSize = 8; int rightSize = 8; ParallelQuery query = ParallelEnumerable.Range(0, leftSize) .Concat(Enumerable.Range(0, rightSize).AsParallel().OrderBy(x => x)); foreach (int i in query) { Console.Write(i + ""|""); } Console.ReadLine(); } ``` (This is a bit of a Heisenbug - expect it to generate completely ordered output on occasion. It's possible that it does this for all input types, and I just haven't seen it yet, although I consider this unlikely) The [ordering page](https://msdn.microsoft.com/en-us/library/vstudio/dd460677%28v=vs.110%29.aspx) states that ordered input to `Concat` results in ordered output, and unordered input results in unordered output, but it isn't clear what happens when you have one of each. At minimum, the output actually observed is disturbing on first encounter. `Zip` appears to operate similar to how I anticipate `Concat` operating - if either input is ordered, the entire output is ordered, regardless of source.

" 1336 area-System.Linq Collections should have extensions to compute order statistic `System.Linq` has extensions implemented for computing the minimum and maximum. Example: ``` C# var a = new int[] {100, 300, 200, 400}; WriteLine(a.Max()); // prints 400 WriteLine(a.Min()); // prints 100 ``` While these are useful values when dealing with collections, they are merely special cases of nth order statistics. More often than not, people are also interested in a specific cases. For example, when querying the collection in the sample code above, the question may be posed, what is the 3rd smallest item in the array? The naive implementation would be to sort the array and print the 3rd item in it. However, there are selection algorithms that can do this more efficiently, without the need to actually invoke a sort method on the array. A method should be implemented in line with the `Min` and `Max` extension methods to accomplish this. The API should be a simple as: ``` C# WriteLine(a.NthSmallestElement(3)) // should print 300 WriteLine(a.NthSmallestElement(1)) // should print 100 WriteLine(a.NthSmallestElement(a.Length)) // should print 400 ``` The method name may differ based on further discussion. I chose the name based on C++ references that I had seen earlier. 1343 area-Serialization Add serialization support for XmlDocument and XmlElement in XmlSerializer Add back the code that was removed when moving serialization to .NET Core.

Instead you have to do something like: ``` csharp var dict = new Dictionary(); foreach (KeyValuePair kvp in enum) { dict.Add(kvp.Key, kvp.Value); } ``` or ``` csharp var dict = enumerable.ToDictionary(kvp => kvp.Key, kvp => kvp.Value); ``` `ConcurrentDictionary` already provides such .ctors. This is especially useful in the case where you want to make a copy of an `IReadOnlyDictionary` ## Proposed API ``` csharp public class Dictionary : ICollection, ICollection>, IDictionary, IDictionary, IEnumerable, IEnumerable>, IReadOnlyCollection>, IReadOnlyDictionary { // New .ctors public Dictionary(IEnumerable> enumerable); public Dictionary(IEnumerable> enumerable, IEqualityComparer comparer); // Existing .ctors public Dictionary(); public Dictionary(IDictionary dictionary); public Dictionary(IDictionary dictionary, IEqualityComparer comparer); public Dictionary(IEqualityComparer comparer); public Dictionary(int capacity); public Dictionary(int capacity, IEqualityComparer comparer); // Remaining members removed for brevity. } ``` See some additional discussion on this issue is at dotnet/coreclr#680 1389 area-System.Reflection Fixes a couple of bugs in debug handle enumerators 1414 area-System.Collections ImmutableList (and Builder) IList.Contains, IndexOf, Remove methods throw instead of return -1 given unexpected argument types A bit longer story http://blog.rthand.com/post/2015/04/10/A-hidden-bug-in-Windows-Stores-ComboBox.aspx Basically a Windows Store (8.1 and 10 at least) ComboBox first tries ComboBoxItem against its ItemsSource IList.IndexOf and if that gracefully fails (returns -1) then it tries with the actual type. This works with normal List because this guy returns -1 when an incompatible type is used, where ImmutableList throws an exception (doesn't do any check actually) and ComboBox doesn't understand that very well. To make it worse ComboBox doesn't perform this stunt immediately but only after a while (when one scrolles some of its items). Now, I'd say that this is ComboBox' fault but who knows. 1415 area-System.Linq Propose: new method Enumerable.IndexOf Hi, I would like to propose a new member for Enumerable class: ``` int IndexOf(IEnumerable source, T item, IEqualityComperer comparer) ``` It's useful to find the index of an item inside the source. Only `IList` has a similar method but it forces me to completely materialize all the source. The implementation can enumerate list or, if the original source type is `IList`, call the `IList.IndexOf` method. If the source type is an `Array` we can call `Array.IndexOf`.

This can be seen [here](https://github.com/dotnet/coreclr/blob/d46b09d4dfc8e25d7e61a9994f89720cf01b5086/src/mscorlib/src/System/TimeZoneInfo.cs#L3754). There are several reasons: - The `AdjustmentRule` class is loaded from registry information, loosely matching the `_REG_TZI_FORMAT` structure. (See [this article](http://blogs.msdn.com/b/bclteam/archive/2007/06/07/exploring-windows-time-zones-with-system-timezoneinfo-josh-free.aspx)). - The whole reason this property was added ([KB3012229](https://support.microsoft.com/en-us/kb/3012229)) is such that the data from the registry can be better reflected in this class. Specifically, the `_REG_TZI_FORMAT.Bias` value can change from year to year, so `AdjustmentRule.BasUtcOffsetDelta` was created to track the delta between the year-to-year bias and the default bias for the time zone. - There's no good reason (IMHO) to keep this internal. Doing so means that the full functionality of the `AdjustmentRule` class can really only be used when populated by the framework itself. It also makes understanding the way that the framework populates the class difficult, as all fields are exposed through public properties _except_ this one. - It creates problems for those trying to use it in other scenarios. See Example 2 in Jon Skeet's post [Backward Compatibility Pain](http://codeblog.jonskeet.uk/2015/03/02/backward-compatibility-pain/). Additionally, there needs to be some public way to create an `AdjustmentRule` that has a value for this property. Either the existing `CreateAdjustmentRule` factory method should be made public, or a parameter could be added to the existing constructor, or another constructor could be added.

The primer I'm working on right now is the primer for the fundamentals of .NET generally, in an ECMA 335 sense. It's intended to be equally meaningful for Mono.

There seems to a problem with ""i"" letter or any other letter that is an inline character for a particular option (i, m, n, s, x). If you change ""i"" with ""a"" (not an inline character), ArgumentException is thrown as expected. Both patterns are invalid so according to the .NET documentation, both lines should throw ArgumentException. This behaviour is especially unpleasant in case of ""regex tester"" application (such as http://regexator.net) which tries to continually evaluate user input as regex pattern. This behaviour has been tested in .NET 4.0, 4.5 and 4.6, all with the same results. " 1477 area-Infrastructure Test infrastructure requirements and scenarios "Current updated proposal from @Chrisboh : **Requirements we need to satisfy** • Run a set of tests that all developers should run before checking in • Specify a set of tests to run from the command line • Be able to debug all test cases • Run with code coverage turned on • Only build what is required ## Proposal The key to this proposal starts at build time. We need to only build what we are going to run. This is important both for overall runtime as well running tests using .net native. In order to satisfy this we need to move our ability to filter up higher in the process. ## Building only What is Required The following include is where we find all of our test projects and add them to the list of items we would like to build. **File:** CoreFX\src\dirs.proj (line 8) `` We need to add a condition to this to only include items that match a supplied filter. This filter would contain the following items. **Filter List:** • InnerLoop • Functional • Partner • Customer #### InnerLoop This will contain everything we consider an Unit test today and until we complete the work to run our tests based on selectivity should be the minimum required set of tests that get run before accepting any PR. #### Functional (OuterLoop Ring 1) This category is made up of test cases that will test larger sections of the code and / or take longer to run. The tests in this category should also give us a quick high level check that there are no major issues with regards to basic performance, stress, or security. #### Partner (OuterLoop Ring 2) The goal of this category is to determine if we are ready for team Dogfooding. All performance and stress tests should be in this category as well as any compliance / security tests. #### Customer (OuterLoop Ring 3) The goal of this category is to determine if we are ready to release this for Partner Dogfooding. This will contain all scenario test cases and will have a manual component added as well. ## Defining Test Project In order for our filtering to work correctly we need to ensure that test project is setup correctly. The simple way to do this is to create a test project for each category in the Filter list. This would give us at most 4 test projects but it will be more typical to have around 2 projects as I could see unifying scenario, compliance, and security tests in a single location. In order to do this we will need to filter by test project name. We will follow the following naming conventions. `*..tests.dll` Example: `System.ObjectModel.InnerLoop.tests.dll` ## Xunit Attributes Now it is time to address what we are going to be doing about the Xunit attributes. First we will remove all attributes that can be replaced with the project filters. This will include things like InnerLoop, OuterLoop, Performance, and Stress. These attributes will not be used when deciding what binaries we should build and run. What this doesn't mean is that we will be removing all attributes entirely. We still need to keep and leverage certain attributes in order to give us the flexibility we need to further fine tune our runs. Here are some of the key attributes we will need to leave in place. #### Active Issue Attribute This attribute will be used to filter out failing test cases when running locally. When running our daily builds we should include these test cases and label them as failing with a known bug. #### Platform Specific Attribute This attribute will be used to filter out test cases that do not apply to the platform you are currently running on. There was some debate on whether we should promote this to the filter list or not. At this time we don’t feel there are enough test cases to warrant promoting this to the filter list. In the future if this becomes an issue we can revisit this. ## Command Line We will need to execute everything from the command line as well as be able to select everything we need. Doing so will be done via two properties. The first will be defining the test categories that you would like to include. This will be done with the following property. `/p:TestTypes=""InnerLoop;Functional""` The second property will be used to supply extra command line parameters to Xunit. This will simply be a pass-through from the msbuild command line onto Xunit and we will use the following property for that. `/p:AdditionalXunitArgs=""-notrait ActiveIssue""` Additionally if you do not specify the TestTypes property it should run all Developer test cases automatically. Also not specifying the AdditionalXunitArgs property should be default exclude any test with an Active Issue and regardless if the property is specified we should include the correct OS parameter. ## Debugging This will be the same as what we have today. In the future we should invest me making the Xunit.runner.VisualStudio work and this would simplify everything. " 1490 area-System.Linq Parallel.Linq.GroupBy not using first 'equal' key. Similar to `Distinct` ( #1330 ), `GroupBy` isn't choosing the 'first' or earliest identical element for a key. That is, given an ordered range `{0, ... 23}`and running `GroupBy(x => x, compareMod(4))`, I'm expecting the first (lowest, here) element that occurs in the source to be chosen as the key - `{0, 1, 2, 3}`. Instead, any element may be chosen as the key (although it looks like `0` is consistently being chosen for the first key... hmmm...)

This means the memory cost of using this data structure for an `ImmutableList` is 1000% on X64, and 600% on X86 (these figures represent the amount of memory used for storing non-data elements associated with the structure). I propose migrating to a B+-tree instead, using a fixed value for _b_ and declaring data values in the index and data pages directly (to avoid unnecessary memory overhead for arrays). The choice of _b_ primarily affects the following things: 1. The height of the tree. Shorter tree heights improve performance for random access lookups by improving memory locality for a majority of traversal operations. 2. The size of the pages. Mutations of immutable data structures require reconstructing pages leading back to the root. If the pages are large, mutations could become expensive. In addition to the above, B+-trees provide a substantial memory savings by removing the child pointers (the Left and Right pointers for AVL nodes) from the leaves. My initial calculations (which could be completely wrong) indicate that the average memory allocation required for a single mutation operation on a list of 100000 elements using the AVL structure is 775 bytes for X64 and 493 bytes for X86. The optimal value of _b_ for X64 in terms of mutation allocation overhead is _b_=8, which costs 476 bytes per operation on a list of the same size (39% reduction). For X86 this same value of _b_ costs 388 bytes per mutation (21% reduction, and _b_=6 would be optimal with 382 bytes). The overall storage overhead for _b_=8 drops a staggering amount down to 169% for X64 and 119% for X86 (counting the average page at 75% capacity, based on a merge at 50% and split at 100%). 1504 area-System.Collections Some Collections.NonGeneric tests have race conditions and ocassionally failing ( http://dotnet-ci.cloudapp.net/job/dotnet_corefx_windows_debug_prtest/963/console ) ``` Xunit.Sdk.EqualException: Assert.Equal() Failure Γåô (pos 0) Expected: en-US Actual: cs-CZ Γåæ (pos 0) at Xunit.Assert.Equal(String expected, String actual, Boolean ignoreCase, Boolean ignoreLineEndingDifferences, Boolean ignoreWhiteSpaceDifferences) at Xunit.Assert.Equal(String expected, String actual) at Comparer_DefaultInvariant.runTest() in d:\j\workspace\dotnet_corefx_windows_debug_prtest\src\System.Collections.NonGeneric\tests\Comparer\Comparer_DefaultInvariant.cs:line 52 Fail! iCountErrors==1 Comparer_DefaultInvariant.ExecuteComparer_DefaultInvariant [FAIL] Assert.True() Failure ``` The tests are setting: ``` csharp CultureInfo.DefaultThreadCurrentCulture = culture; CultureInfo.DefaultThreadCurrentUICulture = culture; ``` Which may fail when run on different threads. 1509 area-System.Numerics Poor hash function in .Net source The `CombineHashCodes` in `System.Numerics.HashCodeHelper` has a very high collision rate for uniformly distributed data! The method probably first appeared in `System.Web.Util.HashCodeCombiner` class and then used in `System.Array`, `System.Tuple` and dotnet/corefx. Here's an example: Assuming the `CombineHashCodes` method's implementation is: ``` C# internal static int CombineHashCodes(int h1, int h2) { return (((h1 << 5) + h1) ^ h2); } ``` 100K raw data results in more than 6K duplicate hash values, that is 6% of a uniformly distributed set: ``` C# var data = Enumerable.Range(0, 100000) .Select(t => new { Val1 = t, Val2 = 100000 + t }) .GroupBy(t => CombineHashCodes(t.Val1.GetHashCode(), t.Val2.GetHashCode())) .Where(t => t.Count() > 1) .Select(t => new { Hash = t.Key, Items = t.ToList() }) .ToList(); ``` I believe there are much better hash functions to use like the one Josh Bloch suggests in Effective Java, which results in no hash collision even for 1M records of data in example above: ``` C# internal static int CombineHashCodes(int h1, int h2) { return (17 * 31 + h1) * 31 + h2; } ``` 1511 area-Infrastructure Remove properties not relevant to code formatting from corefx.vssettings "Looks like we have a few properties that are unrelated to formatting in corefx.vssettings such as: ``` 0 2 ``` We should remove them so that only C# formatting settings are in that file.

The `params char[] separator` overload is particularly insidious as the `params` usage often results in a large number of unnecessary `char[]` heap allocations, unbeknownst to the developer. ## Rationale and Usage [Stack Exchange ran into this](http://blog.marcgravell.com/2013/11/allocaction-allocation-allocation.html) (significant number of separator arrays in memory) and submitted a [pull request](https://aspnetwebstack.codeplex.com/SourceControl/network/forks/marcgravell/outputcachecleanup/contribution/7201) to ASP.NET MVC to cache `String.Split` separator arrays inside the ASP.NET MVC codebase. They ended up with the following: ``` c# namespace System.Web.Mvc { internal static class StringSplits { // note array contents not technically read-only; just... don't edit them! internal static readonly char[] Period = new[] { '.' }, Comma = new[] { ',' }; } } ``` With uses of `string.Split('.')` and `string.Split(',')` replaced with `string.Split(StringSplits.Period)` and `string.Split(StringSplits.Comma)` to avoid the `char[]` allocations. It'd be awesome if `String.Split` offered overloads that accepted a single separator to avoid this. ## Proposed API ``` c# public partial class String { // Proposed methods public string[] Split(char separator, StringSplitOptions options = StringSplitOptions.None); public string[] Split(char separator, int count, StringSplitOptions options = StringSplitOptions.None); public string[] Split(string separator, StringSplitOptions options = StringSplitOptions.None); public string[] Split(string separator, int count, StringSplitOptions options = StringSplitOptions.None); // Existing methods public string[] Split(params char[] separator); public string[] Split(char[] separator, int count); public string[] Split(char[] separator, StringSplitOptions options); public string[] Split(char[] separator, int count, StringSplitOptions options); public string[] Split(string[] separator, StringSplitOptions options); public string[] Split(string[] separator, int count, StringSplitOptions options); } ``` ## Notes We had wanted to add `public string[] Split(string separator)`, but this breaks source compatibility with uses of `Split(null)`, which is documented to split based on white space, because it makes the call ambiguous between `Split(char[])` and `Split(string)`. I won't go into it here as it's really a separate feature request, but it would also be worth considering new `Split` methods that return a `struct` collection of `StringSpan`/`StringSegment` structs (in lieu of internal runtime span/substring magic) to avoid the resulting `string[]` allocation (and substring allocations, unless needed). I'd be happy to contribute an implementation and tests. 1514 area-System.Runtime Add String.Format overloads to avoid unnecessary allocations "It's pretty common to pass value types to `String.Format`, unfortunately this results in unnecessary boxing allocations. ## Rationale Consider the following: ``` c# long id = ...; int index = ...; int length = ...; // Traditional call to String.Format string foo = string.Format(""{0}: Index = {1}, Length = {2}"", id, index, length); // Use of the string interpolation language feature string bar = $""{id}: Index = {index}, Length = {length}""; ``` Both the traditional call to `String.Format` and the use of the string interpolation language feature (which is just syntactic sugar for `String.Format`) requires 3 boxing allocations. ## Proposed API ``` c# namespace System { public sealed class String : ... { // Proposed methods public static string Format(string format, T0 arg0); public static string Format(string format, T0 arg0, T1 arg1); public static string Format(string format, T0 arg0, T1 arg1, T2 arg2); public static string Format(IFormatProvider provider, string format, T0 arg0); public static string Format(IFormatProvider provider, string format, T0 arg0, T1 arg1); public static string Format(IFormatProvider provider, string format, T0 arg0, T1 arg1, T2 arg2); // Existing methods public static string Format(string format, object arg0); public static string Format(string format, object arg0, object arg1); public static string Format(string format, object arg0, object arg1, object arg2); public static string Format(string format, params object[] args); public static string Format(IFormatProvider provider, string format, object arg0); public static string Format(IFormatProvider provider, string format, object arg0, object arg1); public static string Format(IFormatProvider provider, string format, object arg0, object arg1, object arg2); public static string Format(IFormatProvider provider, string format, params object[] args); ... } } namespace System.Text { public sealed class StringBuilder { // Proposed methods public StringBuilder AppendFormat(string format, T0 arg0); public StringBuilder AppendFormat(string format, T0 arg0, T1 arg1); public StringBuilder AppendFormat(string format, T0 arg0, T1 arg1, T2 arg2); public StringBuilder AppendFormat(IFormatProvider provider, string format, T0 arg0); public StringBuilder AppendFormat(IFormatProvider provider, string format, T0 arg0, T1 arg1); public StringBuilder AppendFormat(IFormatProvider provider, string format, T0 arg0, T1 arg1, T2 arg2); // Existing methods public StringBuilder AppendFormat(string format, object arg0); public StringBuilder AppendFormat(string format, object arg0, object arg1); public StringBuilder AppendFormat(string format, object arg0, object arg1, object arg2); public StringBuilder AppendFormat(string format, params object[] args); public StringBuilder AppendFormat(IFormatProvider provider, string format, object arg0); public StringBuilder AppendFormat(IFormatProvider provider, string format, object arg0, object arg1); public StringBuilder AppendFormat(IFormatProvider provider, string format, object arg0, object arg1, object arg2); public StringBuilder AppendFormat(IFormatProvider provider, string format, params object[] args); ... } } namespace System.Runtime.CompilerServices { public static class FormattableStringFactory { // Proposed methods public static FormattableString Create(string format, T0 argument0); public static FormattableString Create(string format, T0 argument0, T1 argument1); public static FormattableString Create(string format, T0 argument0, T1 argument1, T2 argument2); // Existing method public static FormattableString Create(string format, params object[] arguments); } } ``` I'd be happy to contribute an implementation and tests.

" 1552 area-System.Reflection Merge 1561 area-System.Linq LINQ's Buffer ctor requires Count/CopyTo results be consistent "LINQ's internal Buffer, which is used in operations like ToArray, OrderBy, Reverse, etc., assumes that if the input `IEnumerable` implements `ICollection`, then CopyTo will be guaranteed to copy the number of items returned previously by Count: https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Enumerable.cs#L3087-L3093 ``` C# int count = 0; ICollection collection = source as ICollection; if (collection != null) { count = collection.Count; if (count > 0) { items = new TElement[count]; collection.CopyTo(items, 0); } } else { foreach (TElement item in source) { if (items == null) { items = new TElement[4]; } else if (items.Length == count) { TElement[] newItems = ArrayT.Resize(items, checked(count * 2), count); items = newItems; } items[count] = item; count++; } } ``` This is problematic for any collection that fails this guarantee, e.g. by design the concurrent collections (`ConcurrentQueue`, `ConcurrentDictionary`, etc.) may have their number of elements change between the call to Count and CopyTo if elements were added or removed concurrently. We could address this in the implementation of Buffer by avoiding the use of CopyTo, e.g. ``` C# int count = 4; ICollection collection = source as ICollection; if (collection != null) { int tmpCount = collection.Count; if (tmpCount > 0) count = tmpCount; } foreach (TElement item in source) { if (items == null) { items = new TElement[count]; } else if (items.Length == count) { TElement[] newItems = ArrayT.Resize(items, checked(count * 2), count); items = newItems; } items[count] = item; count++; } ``` This turns Count into an estimate rather than a guarantee, avoiding the problem. However, it has the downside of having a (potentially) less efficient copy mechanism for other `ICollection` implementations, including an `IEnumerator` allocation used in the foreach. That said, it's not clear to me how often we hit the ""fast"" CopyTo path anyway; many collection types have their own ToArray method, so if the LINQ method is being used, it's likely because there are other LINQ operators in the middle, e.g. `collection.Where(...).Select(...).ToArray()`, in which case the optimization will not apply. A few possible options: 1. We say that concurrent collections may not be used concurrently with LINQ operations. Developers may of course already be doing this, and since you can pass concurrent collections around as `IEnumerable`, the developer may not even know they're using concurrent collections but may silently either get corrupted data (e.g. the count drops after allocating the array, leaving default elements at the end of the array) or exceptions (e.g. CopyTo tries to copy more elements than the array can hold). 2. We make the above change, such that we no longer require the Count == CopyTo size guarantee, potentially special casing some known types like `List`, `Collection`, etc. and some known other situations, e.g. IsReadOnly returning true. 3. We special-case the known-problematic cases in the framework, namely the Concurrent\* collections, and do the second option above just for those. We could add a marker interface or something to more easily identify them, which would also allow other collections to opt-out of such things as well. 4.

An example where that's not the case is, `String.Contains`. We should to a holistic pass to make sure we don't miss others. 1571 area-System.IO Add TextWriter.Write(string value, int index, int count) overload TextWriter has an overload for writing a segment of a char array with this Write overload: void Write(char[] buffer, int index, int count) But TextWriter doesn't have an overload for writing a segment of a string, e.g.: void Write(string value, int index, int count) This means that in cases where you have a segment of a string that you want to write you either need to either substring and pass that value to Write(string) or copy the string to a char array and then use the char array segement overload. It would be a new virtual method but the default implementation could simply call the current Write(char[] buffer, int index, int count) overload. The main problem I see with adding Write(string, int, int) is there is a Write(string, object, object) overload that does string formatting that would be hidden. Avoid with different name? Example of having to having to use the Write(char[] buffer, int index, int count) overload where a string overload would simplify code and improve performance: https://github.com/JamesNK/Newtonsoft.Json/blob/6a22345e28006d74c25e353b6235bc5222bab821/Src/Newtonsoft.Json/Utilities/JavaScriptUtils.cs#L220-L228 1577 area-System.Net HttpPrefixes So http prefixes ... Its an IIS specific API that makes zero sense when IIS is no longer present. I know this code hasn't come over yet code wise but I figured I would create an issue for it for discussion about what may happen. As an example I want to: Bind to 192.168.1.101 : 1111 Allow an elastic ip with a round robin dns to be used. In mono as example this will cause it to bind *:1111 and allow which is totally not what I wanted, there is no good way in the current api of actually specifying. I can specify 192.168.1.101:1111/ just fine. What happens when I as well specify myroundrobindns:1111/? Do I mean that I want to allow this host header or to bind to this interface? This is where the problem starts.... What if I only specified the myroundrobindns:1111? Then it would make sense to bind all or give me an error (without IIS). But this behaviour makes it impossible to do the above (common use case). There are literally dozens of derpy little gotchas like this (and no good way of working around them) due to how the api is laid out and not wanting to break compatibility with msclr. Whats the plan for CoreFX? Thoughts? Greg 1582 area-Infrastructure XML test libs included in coverage report I looked at the coverage report and noticed that a bunch of XML test libs are included: ![image](https://cloud.githubusercontent.com/assets/1376924/7392228/d392bf42-ee86-11e4-8254-db6d5ee5e20f.png) Those are dragging the overall coverage down and should be excluded from coverage. /cc @krwq 1583 area-System.Runtime Add generic overloads to Math.Min and Math.Max There are overloads of `Math.Min` and `Math.Max` for all the numeric types, but there aren't any for general comparable types (including framework types like `DateTime` and `TimeSpan`). It would be nice to have them. ## Rationale For integral types, `Math.Min` and `Math.Max` are not necessary, e.g. instead of `Math.Min(a, b)`, you can write `a <= b ? a : b`. But they are nice, because they make the meaning clear and decrease the likelihood of error. The same argument applies to general comparable types, so they should work with `Math.Min` and `Math.Max` too. ## Proposed API ``` c# public static class Math { public static T Min(T val1, T val2) where T : IComparable; public static T Min(T val1, T val2, IComparer comparer); public static T Max(T val1, T val2) where T : IComparable; public static T Max(T val1, T val2, IComparer comparer); } ``` ## Open questions - Should the constraint `where T : IComparable` be there? Other framework methods that require comparison, like `Enumerable.OrderBy`, don't have it and instead use `Comparer.Default`. - Should nullable value types be supported? The proposed version doesn't, because `T?` does not implement `IComparable`, even when `T` does implement `IComparable`. 1586 area-System.Net Initial open sourcing of System.Net.Http code. 1591 area-System.Reflection System.Reflection.Metadata.MetadataReader.MetadataReader consistently throws InvalidOperationException in store app I'm able to use System.Reflection.Metadata without any problems in my .NET 4.5.1 desktop app, but I'm unable to successfully use it in a Windows Store app--I consistently see this exception getting thrown: ``` System.InvalidOperationException occurred Message: Exception thrown: 'System.InvalidOperationException' in mscorlib.ni.dll Additional information: The API 'System.Text.Encoding.GetString(Byte*, Int32)' cannot be used on the current platform.

XPathNodeIterator always iterates over objects of type XPathNavigator and thus every usage ends up with casting back and forth XPathNavigator --> object --> XPathNavigator in a loop. Implementing IEnumerable on this type would allow to avoid this indirection and in cases where iterating is useful improve perf. cc: @tmat EDIT 2017/12/28: In PR: https://github.com/dotnet/corefx/pull/26083 Requested API changes: ```diff namespace System.Xml.XPath { ... - public abstract class XPathNodeIterator : ICloneable, IEnumerable + public abstract class XPathNodeIterator : ICloneable, IEnumerable ... ``` 1595 area-System.Xml Add XmlReader.ResetState to enable pooling (modified copy of internal bug / cc: @tmat) The XmlReader allocates char[] and byte[] buffers in its ParseState. XmlReader created via XmlReader.Create doesn't expose ResetState method that would allow pooling. XmlTextReader does, however the class is legacy and not available on new platforms (in portable profile). Or in simple words: put multiple xml files in one stream and try to parse it without creating multiple XmlReader instances which do a lot of allocations. Simple scenario is reading xml doc comments by Roslyn 1596 area-System.Globalization Randomized Hashing APIs Proposal is to add APIs which expose old hashing methods and the new one (old ones are non randomized). Background: On some platforms default is to use randomized hashing and on some it is non randomized. Exposing APIs allows devs to make it explicit so in case we want to always use randomized hashing for security reasons we can do it or if we want the hashing to be faster we can use non randomized. (Some work might need to be done in dotnet/coreclr) This was already reviewed internally once although here is another iteration. Proposal is to add following APIs ``` csharp //assembly System.Globalization { namespace System.Globalization { public class CompareInfo { public virtual int GetHashCode(string source, CompareOptions options, HashingOption hashingOption); } // enum numbers should be explicit in the final version public enum HashingOption { //Default, ??? NonRandomized, Randomized, } } //} //assembly System.Globalization.Extensions { namespace System.Globalization { public static class GlobalizationExtensions { public static StringComparer GetStringComparer(this CompareInfo compareInfo, CompareOptions options, HashingOption hashingOption); } } //} //assembly System.Runtime.Extensions { namespace System { public abstract class StringComparer : IComparer, IComparer, IEqualityComparer, IEqualityComparer { public static StringComparer OrdinalNonRandomized { get; } public static StringComparer OrdinalIgnoreCaseNonRandomized { get; } public static StringComparer OrdinalRandomized { get; } public static StringComparer OrdinalIgnoreCaseRandomized { get; } } } //} ``` 1597 area-Infrastructure Running CoreFx tests from VS is broken I’m using TestDriven.NET. 1) Right-click on a test method and selecting “Run Test” works well for System.Reflection.Metadata tests. Good. 2) Right-click on a test class or a test file reports an error in output: The target type doesn't contain tests from a known test framework or a 'Main' method. 3) Right-click on a test method and selecting “Test with … Debugger” freezes VS. Test Explorer doesn’t show any tests even after full solution build. Trying to set the test project as a startup project and F5 it. Error: “The working directory does not exist: 'C:\FX0\bin\tests\Windows_NT.AnyCPU.Debug\System.Reflection.Metadata.Tests\dnxcore50'.” Seems like building the entire CoreFx repo fixes this issue (although I’m not quite sure). In any case I don’t want to build the entire repo to run a single test. Couldn’t get F5 work from Dev12 VS, yet the project is Dev12 VS. With Dev14 I was able to debug the test. 1598 area-Meta Improve layout of bin\tests directory Building and running all CoreFx tests creates bin\tests directory with an insane amount of files (14493 files of total size 1.4GB). The problem is that every CoreFx library deploys its own copy of DNX and XUnit (175 files) to its test directory. Instead all tests should be deployed into a single directory with a single copy of DNX. 1603 area-Meta Add inner and outer loop testing explanation to Developer Guide 1605 area-System.Numerics Add Conversions methods to Vector It would be useful to support conversions between different types of Vector. The API and usage model is pretty straightforward for same-size types, e.g. Double and Int64, so I would suggest that we start by exposing that, and consider mixed-size converts as usage demands (we have had customer requests for at least the same-size convert). A possible instance method on Vector might look like this: public Vector ToVectorDouble(); and it would throw arg exception for non-64-bit vectors (or, alternatively, it could be defined as an extension method on the static Vector class for only those instantiations that are supported). I propose the following: - `Vector <=> Vector` - `Vector <=> Vector` - `Vector <=> Vector` - `Vector <=> Vector` 1608 area-System.Numerics Add Gather methods for Vector Vector Gathers are a commonly used paradigm in vector computation - where a gather involves constructing a vector from non-contiguous elements of a source array. Gather is supported on AVX2, but even on targets that do not directly support it, such a method would be useful, in order to avoid the overhead of having to use an array to hold the elements prior to contructing the Vector. VectorGather should perhaps be declared on the static Vector class, something like: `public static Vector VectorGather(T[] source, Vector indexVector) where T,U : struct` Initially, I think it would be reasonable to support only same/size convert and gather – but eventually we may want to consider mixed size (e.g. a gather to a Vector using the lower values of a Vector. AVX2 has a pretty rich mixture of these. @mellinoe what do you think? 1609 area-System.Diagnostics System.Diagnostics.Debug.Tests does not build on Linux System.Diagnostics.Debug.Tests currently fails trying to resolve types against System.Runtime. It is disabled in dir.props. 1611 area-System.Net HttpResponseHeader should have a Cookies property Hello, The HttpResponseHeader class (found at https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Headers/HttpResponseHeaders.cs ) doesn't seem to include a standard and pretty trivial header, the Cookies header. Furthermore, as suggested by http://www.asp.net/web-api/overview/advanced/http-cookies, we should use the HttpResponseHeadersExtensions, found at https://aspnetwebstack.codeplex.com/SourceControl/latest#src/System.Net.Http.Formatting/HttpResponseHeadersExtensions.cs , however, as you can see in the code (and in the CookieHeaderValue class) - there's no way to configure default values, e.g. HttpOnly or Secured. In a regular ASP.NET website we can set the default values in web.config, but since ASP.NET WebAPI doesn't rely on that, there's no way, even in the WebAPI configuration registering method to set such values. Part from creating my own extension to add cookies with default values, I would suggest adding support for cookies in the HttpResponseHeaders class and having the option to set default values in registration time. Thank you very much. 1612 area-System.Data System.Data.SqlClient.SqlParameter Precision and Scale do not work via the abstract API "Package from dnxcore50 via ``` ""System.Data.SqlClient"": ""4.0.0-beta-*"", ``` This works: ``` SqlParameter p = ... p.Precision = 10; p.Scale = 5; ``` However, if instead we use the abstract base class (like most tools will be): ``` SqlParameter p = ... DbParameter d = p; d.Precision = 10; d.Scale = 5; ``` then all of `p.Precision`, `p.Scale`, `d.Precision`, `d.Scale` **remain at 0**, and consequently do not work correctly. The abstract API's `Scale` and `Precision` (and any other associated members) should mirror the concrete type's equivalent. This code is not in corefx yet, so I cannot fix it :( " 1613 area-System.Data System.Data.SqlClient does not allow enum parameters values (it does in .NET) "Is this an expected break? For example: ``` using (var cmd = connection.CreateCommand()) { cmd.CommandText = ""select @foo""; cmd.Parameters.AddWithValue(""@foo"", AnEnum.B); object value = cmd.ExecuteScalar(); AnEnum val = (AnEnum)value; // cheeky unbox behavior val.IsEqualTo(AnEnum.B); } enum AnEnum { A = 2, B = 1 } ``` In .NET this works fine; in CoreCLR this breaks on the `ExecuteScalar()` call, reporting an `ArgumentException` with text: > No mapping exists from object type AnEnum to a known managed provider native type. " 1616 area-System.Numerics bug: Vector extracting components with a literal leads to incorrect code gen. It appears that if you try to retrieve components of a `Vector` with a constant something wrong is occurring and an incorrect code is generated. This does not happen when extracting to an array, or when you use a variable (like say through a for-loop). This only happens when you extract literal components. Here is a simple reproduction. This happened in VS2015 RC ``` csharp static bool TestLiterals(Vector vl) { var v = vl[0]; var v1 = vl[1]; var v2 = vl[2]; var v3 = vl[3]; return v != 0 || v1 != 0 || v2 != 0 || v3 != 0; } static bool TestLoop(Vector vl) { for(int i=0; i < Vector.Count; i++) { var v = vl[i]; if (v != 0) return true; } return false; } static void Main(string[] args) { var array = new long[4] { 0, 0, 0, 1 }; var vector = new Vector(array); Console.WriteLine(Vector.Count); Console.WriteLine(TestLiterals(vector)); Console.WriteLine(TestLoop(vector)); } ``` On my i5 broadwell chip it printed: ``` 4 False True ``` This is very much the wrong result. The correct answer should be: ``` 4 True True ``` It's pretty easy to see that both methods should yield the same result. Here is the assembly of the `testliteral` And the error becomes obvious. ``` **00007FFB1E086E20 vmovupd ymm0,ymmword ptr [rcx] 00007FFB1E086E25 vmovd rax,xmm0 ** **00007FFB1E086E2A vmovupd ymm0,ymmword ptr [rcx] 00007FFB1E086E2F vmovaps ymm1,ymm0 00007FFB1E086E34 vpsrldq ymm1,ymm1,8 00007FFB1E086E3A vmovd rdx,xmm1 ** 00007FFB1E086E3F vmovupd ymm0,ymmword ptr [rcx] 00007FFB1E086E44 vmovaps ymm1,ymm0 00007FFB1E086E49 vpsrldq ymm1,ymm1,10h 00007FFB1E086E4F vmovd r8,xmm1 00007FFB1E086E54 vmovupd ymm0,ymmword ptr [rcx] 00007FFB1E086E59 vmovaps ymm1,ymm0 00007FFB1E086E5E vpsrldq ymm1,ymm1,18h 00007FFB1E086E64 vmovd rcx,xmm1 00007FFB1E086E69 or rax,rdx 00007FFB1E086E6C or rax,r8 00007FFB1E086E6F test rax,rax 00007FFB1E086E72 jne 00007FFB1E086E7E ``` The input vector is in `ymm0` and it is using `ymm1` as its scratch buffer, first copying and then shifting the register by the offset but is trying to pull the component out of `xmm1`! It appears that the compiler while having some concept of AVX registers, is still confused. 1617 area-System.Numerics Vector should allow variable length based size of available registers. Currently, it seems that `Vector` will always be the size of the largest available register, and has no support for using a smaller register. E.g. if you have AVX2, you currently can only build `Vector` of 256bit. For some algorithms it can be very useful to be able to use either a vector of size 16 or a vector of size 32. 1622 area-Infrastructure Consider open sourcing ApiCompat. Internally we have some tooling to ensure that implementation assemblies are compatible with contracts. It would be a good idea to open source that and use it as part of the build or CI system or something. I'm not sure if this will happen naturally when we actually start generating contracts in the open or if we'll need to take extra steps. 1624 area-System.Net An simple way to mock an httpClient.GetAsync(..) method for unit tests? `System.Net.Http` has now been uploaded to the repo :smile: :tada: :balloon: Whenever I've used this in some service, it works great but makes it hard to unit test => my unit tests don't want to actually ever hit that real end point. Ages ago, I asked @davidfowl what should we do? I hoping I paraphrase and don't misquote him - but he suggested that I need to fake up a message handler (ie. `HttpClientHandler`), wire that up, etc. As such, I ended up making a helper library called [HttpClient.Helpers](https://github.com/PureKrome/HttpClient.Helpers) to help me run my unit tests. So this works ... but it feels _very_ messy and .. complicated. I'm sure I'm not the first person that needs to make sure my unit tests don't do a real call to an external service. Is there an easier way? Like .. can't we just have an `IHttpClient` interface and we can inject that into our service? 1625 area-System.Runtime "[public api] System.Runtime.Environment - OSName(""FreeBSD"") or OSName(""BSD"")" "This issue is to discuss what the final identifier will be within the entire public API surface and what will be the build target identifier that msbuild will use. https://github.com/dotnet/corefx/issues/1576 started the discussion of wether to use `OSName(""FreeBSD"")` vs `OSName(""BSD"")` in the unit tests and is recommended reading before progressing with reading this issue. `FreeBSD` won but it can be easily refactored due to being a non-public contract. The BSD's (FreeBSD/NetBSD/OpenBSD/DragonFlyBSD) unlike Linux all have different kernels so potentially it might be required to split them out as separate platforms. This might be completely unnecessary whereby the additional BSD's may just work as a direct result of the port team's efforts. There are enough differences between the different BSDs that it could be needed to differentiate between them however. We have some time before a decision needs to be cemented in as there is a more pressing issue as mentioned by @stephentoub and registered as issue #1626 > There's what's likely a more pressing issue, which is actually building for FreeBSD. Today, when we need to specialize an assembly for a particular platform, we effectively have three builds, producing three different managed assemblies: Windows, Linux, OSX. Sounds like at least for now we'll need a fourth, FreeBSD. I suggest you start by modifying the build to support an IsFreeBSD property (or just IsBSD of you think there's a high chance that the implementations across BSDs will be the same even with varied kernels) along with the appropriate OSGroup targets. That can then be used in the csproj files as needed to specialize an assembly with FreeBSD-specific code. I feel uneasy about using either `OSName(""FreeBSD"")` (platform fragmentation) or `OSName(""BSD"")` (too generic) with the amount of information available at this point in time but obviously a direction needs to be chosen. @janhenke @josteink (core members of the portteam) have put forward on multiple times that they would prefer `FreeBSD` and I have no strong preferences in any which direction as long as the _future_ implications are considered carefully because this decision affects the public API surface. Ultimately advice, direction and a decision will be needed by MSFT on this matter. note: issue was edited/refactored based on feedback from josenink since original post. " 1626 area-Meta Support for FreeBSD ## Updated proposal from 2017/9 Proposal (by @karelz - https://github.com/dotnet/corefx/issues/1626#issuecomment-329840518) will be updated in top-post based on further discussion and proposal changes. We discussed community-driven port for FreeBSD with @RussellHaley (from FreeBSD community) and @wfurt (from .NET Core team) who both expressed interest in the work. Here's a plan proposal we put together (feedback / suggestions are welcome): 1. Produce binaries in CoreCLR & CoreFX repo targeting FreeBSD - using hacks is fine * Hard to parallelize, @wfurt will work on that * The build can be mix of builds from other platforms (Mac, Linux) targeting FreeBSD * We will need documented steps (on FreeBSD wiki) to reproduce the build with FreeBSD-specific bug fixes 2. Run & stabilize CoreCLR tests (using corerun) * Tests may be built on another platform * Goal: Provides basic quality of runtime 3. Run & stabilize CoreFX tests (using corerun) * Tests may be built on another platform * Note this requires xunit. We believe, based on our past porting experience, once [2] is done, xunit will just work. * This can be in theory parallelized with [2] - it may require shortcutting xunit (e.g. generate static execution recipe on another platform) * We can expose new OSPlatform API for FreeBSD when the pass rate is reasonable: see #23989 4. Full stack build on FreeBSD (using corerun as bootstrapper from [1]-[3]) * We will need all tools (nuget, msbuild, roslyn) to work on boostrapping .NET Core 5. Installers (FreeBSD ports) * First-stage: Using product binaries from nuget feeds * Second-stage: Build product from source (blocked on build from source effort) * Requires FreeBSD community expertise and guidance on design * Note: We can link FreeBSD packages also from official .NET Core download pages as community-support packages 6. Regular build and test runs on FreeBSD * Goal: Make sure changes in .NET Core repos breaking FreeBSD are known early * Design needed * Requires FreeBSD community expertise and guidance on design Operation principles: * Changes in [2]-[4] should be done primarily in CoreCLR/CoreFX repos (due to CLA signing requirements, code reviews from .NET Core team experts/members. etc.) * We will track high-level work on this issue. Specific bugs will be filed as separate issues. If anyone is interested in helping, please let us know here. We can easily distribute work items from [2] & [3] above once we are far enough with [1]. --------------------------------------------- ## Original proposal from @ghuntley from 2015/5 This issue is to discuss unit(s) of work to actually produce FreeBSD assemblies for corefx. > @stephentoub - There's what's likely a more pressing issue, which is actually building for FreeBSD.

I suggest you start by modifying the build to support an IsFreeBSD property (or just IsBSD of you think there's a high chance that the implementations across BSDs will be the same even with varied kernels) along with the appropriate OSGroup targets. That can then be used in the csproj files as needed to specialize an assembly with FreeBSD-specific code. Related issue(s) - #1625 (OSGroup identifier in the public API) - #1576 (OSGroup identifier in the private API) /cc: @janhenke @josteink 1633 area-System.Reflection More offsets in MetadataReader I believe MetadataReader should have more APIs which tell me about offsets. I. e.: Let's say I'm writing strong name signer, there are few steps required (assuming that assembly is already delayed signed): - calculate hash, - sign hash, - inject signature to calculate hash you need to skip some parts of the PE file like: - strong name signature blob (including the 8 bytes in the header) - certificates blob (including 8 bytes header) - checksum so I need to have offsets and sizes for each of those. For blobs there are already APIs: i.e.: ``` peReader.PEHeaders.CorHeader.StrongNameSignatureDirectory.Size peReader.PEHeaders.CorHeader.StrongNameSignatureDirectory.RelativeVirtualAddress peReader.PEHeaders.PEHeader.CertificateTableDirectory.Size peReader.PEHeaders.PEHeader.CertificateTableDirectory.RelativeVirtualAddress ``` what is missing is: - checksum offset (and optionally a size) - blob headers for blob headers we can do simple change in System.Reflection.PortableExecutable.DirectoryEntry which is: ``` diff public struct DirectoryEntry { //... + public readonly int HeaderOffset; //... internal DirectoryEntry(ref PEBinaryReader reader) { + HeaderOffset = reader.CurrentOffset; RelativeVirtualAddress = reader.ReadInt32(); Size = reader.ReadInt32(); } //... } ``` For stuff like CheckSum offset we need something like this: ``` diff public sealed class PEHeader { //... + public int BaseOffset; // this might be always 0 so const would be fine too //... + public const int CheckSumOffset; + public const int CheckSumSize; + //etc. for other fields } ``` cc: @nguerrera @tmat What are your thoughts? With good modifications we could probably reuse some of those types when writing MetadataWriter (assuming we are planning to do that) 1635 area-System.Security System.Security.Cryptography.Hashing.Algorithms cannot resolve System.Text.Encoding and System.Threading.Tasks ?

An SHA-1 hash over most of the PE file is generated. That hash value is RSA-signed with the SN private key. For verification purposes the public key is stored into the PE file as well as the signed hash value. - Except for the following, all portions of the PE File are hashed: - The Authenticode Signature entry: PE files can be authenticode signed. The authenticode signature is contained in the 8-byte entry at offset 128 of the PE Header Data Directory (“Certificate Table” in §II.25.2.3.3) and the contents of the PE File in the range specified by this directory entry. [Note: In a PE File conforming to this specification, this entry shall be zero. end note] - The Strong Name Blob: The 8-byte entry at offset 32 of the CLI Header (“StrongNameSignature” in §II.25.3.3) and the contents of the hash data contained at this RVA in the PE File. If the 8-byte entry is 0, there is no associated strong name signature. - The PE Header Checksum: The 4-byte entry at offset 64 of the PE Header Windows NT-Specific Fields (“File Checksum” in §II.25.2.3.2). [Note: In a PE File conforming to this specification, this entry shall be zero. end note] What we actually do is (hashing): - In CorHeader/CLI Header set StrongNameSigned flag (value: 8). (I believe this is starting on 12th byte of CLI Header and is UInt32 - do not remove the old flag value just do bitwise OR with value 8) - Set Checksum (4 bytes) to zeros (this is in optional PE header in NT specific fields) - Set Certificate Directory entry (only 8 byte header) to zeros - Calculate hash of PE header from the start until sections headers are finished. Notes: - Continue hashing each section in the order of occurrence in the headers (this will start immediately after section headers and will intentionally skip padding after section headers). Note: - Strong Name Directory - entirely skip from hashing (but do hash its data directory 8 byte header as is) After we get a hash we sign it and store in Strong Name Directory 1683 area-Infrastructure System.Collections.Tests runs against Nuget package not compiled output "Unit tests in System.Collections.Tests.csproj appear to execute against the System.Collections package, and not the compiled output in the bin folder.

Consider the scenario where one constructs an instance of the Uri class with the path ""www.domain.com"". As expected, this evaluates to a relative path, because the protocol has not been specified. However, absolute or not, one would expect the value of its Uri.HostNameType to be UriHostNameType.Dns. Instead, checking the HostNameType throws an exception. This particular scenario also exhibits an inconsistency with other members of the Uri class. Uri.CheckHostName(string name) is a static method which returns a UriHostNameType value, just the same as the Uri.HostNameType instance property. One could reasonably expect the following two calls to return the same value: var hostType = new Uri(""www.domain.com"", UriKind.RelativeOrAbsolute).HostNameType; var hostType = Uri.CheckHostName(""www.domain.com""); Unfortunately, the first call throws an exception. The second call using CheckHostName, however, returns the expected value: UriHostNameType.Dns.

Enumerables throwing an exception during `GetEnumerator()` will expose the original exception, and won't wrap it in `AggregateException` (which at least a naïve reading of the documentation suggests it should), for everything but the following 'output' methods: - `Average` - `Count` - `LongCount` - `Max` - `Min` - `Sum` ... and `SequenceEqual`, but only when some other method is called first (eg, `new FailingEnumerable.AsParallel().Select(x => x).SequenceEquals(b)`). If the enumerator itself throws an exception (from `MoveNext()` or `Current`), and additional PLINQ method is called first: 1. `SequenceEqual` throws nested `AggregateException`s 2. The following 'output' methods throw the original exception, and will not wrap it in an `AggregateException`: - `Aggregate(seed, accumulator)` - `Aggregate(seed, accumulator, resultSelector)` - `foreach(...)` - `ToArray` - `ToDictionary` - `ToList` This is, at minimum, a 'gotcha' waiting to trip somebody up. How should we handle it? Interestingly, `SequenceEqual` has: > // If first.GetEnumerator throws an exception, we don't want to wrap it with an AggregateException. > // If second.GetEnumerator throws an exception, we don't want to wrap it with an AggregateException. ... which I have a feeling was to deal with the case where an inner operator threw something already wrapped (to not nest it), but ended up missing the other cases.

This involves either creating a new library or a newer version of an existing one. As a minimum it should support the same client API surface as the full .NET Framework. This is required for WCF to complete its NetTcpBinding implementation. 1849 area-System.IO Unix: Why not use Unix Domain Sockets for Named Pipes? System.IO.Pipes map to native windows implementations of anonymous and named pipes. Windows anonymous are close in implementation to Unix pipes in that they are one way and byte oriented (not datagram or message oriented). On the other hand, Named pipes can be either full (supporting I/O in both directions) or half (I/O in one direction) and messages can either be byte oriented or message/datagram oriented. Pipe connections can also be made across systems through the network (I believe using SMB) Unix has named pipes called FiFo's but they are one way only and not message oriented. The current Pipes port for corefx under unix uses FIfo's and therefore is a subset implementation. Instead of using Fifo's why don't we use Unix Domain Sockets? They support most of the functionality of windows named pipes including full/half duplex, byte or message oriented. They however don't support cross system connections. see overview of Unix Domain Sockets here: http://www.thomasstover.com/uds.html Ultimately, what is the goal of the corefx library on a different platform? To bind to existing similar functionality? or to provide strict portability of the api's across platforms (what I'm calling emulation)? If we strictly bind, then there will always be limitations and differences on functionality provided thus decreasing portability. However by binding, we are hooking into existing OS capabilities and can in theory hook up to other non-net apps on the host platform. If we strictly emulate (e.g. say grab a chunk of shared memory and then using semaphores to strictly emulate named pipes functionality under Unix), then we can be extremely portable however we can't communicate with anything else. A possible solution is to extend what can be used as a 'pipe name' in the system.io.pipes implementation where the syntax can be extended to give hints as to what to bind to in the underlying implementation but with the default (without any extended syntax) defaulting to an emulated functional solution.

This started around here: http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst/264/ Which had these changes: Update to latest CoreFx packages (commit: 08c0d8628ef621fbd44d7aaa85b3239616a6b108) Move DNU/Roslyn forward (commit: 804b4330a6ae767694cf89ebd173533b539f16f5) The problem looks to be due to the fact that we are now copying mscorlib.ni.dll into the test folder. This is not a Linux native image so things blow up when we try to load and run it. To unblock things, I am adding some logic to run-tests.sh to just delete the native images, but that's not the right long term thing (especially with crossgen support coming real soon now). We need to stop this incorrect native image from being deployed, and eventually deploy the right one. This issue tracks doing the right thing.

By default the FSW should buffer events in ""normal"" memory. This could easily be implemented using a BlockingCollection. FSW could be configurable to use the old behaviour only. For details and and a implementation sample see my post: https://petermeinl.wordpress.com/2015/05/18/tamed-filesystemwatcher/ Average programmers (for which we should make life as easy as reasonable) often are often not even aware of having to implement an OnError event handler resulting in InternalBufferOverflowExceptions going unnoticed and FSW being perceived as unreliable. " 1883 area-System.Numerics Buffer too small in BigIntegerCalculator.Divide We are seeing some memory corruption after a recent change to biginteger.divide. This is what I got from an engineer investigating the issue: I was able to repro this bug and find its cause. The bug is in System.Runtime.Numerics.dll, introduced by change #1476305 on 5/23. There is an array overflow in unsafe C# code that does division of BigInteger, in System.Numerics.BigIntegerCalculator.Divide(UInt32_, Int32, UInt32_, Int32, UInt32_, Int32, UInt32_, Int32) in FxCore/Open/src/System.Runtime.Numerics/src/System/Numerics/BigIntegerCalculator.DivRem.cs. This method allocates a few arrays: ``` fixed (uint* dividend = new uint[dividendLength], divisor = new uint[divisorLength], guess = new uint[divisorLength]) ``` The guess array is used as the destination of a multiplication: MultiplyDivisor(divisor, divisorLength, digit, guess); This multiplies an array of length divisorLength with an uint. The result length is divisorLength+1, longer than the memory allocated for guess. This overwrites the sync block of the next item in memory, causing asserts later on. Increasing the allocation of guess by 1 should fix this bug. 1891 area-Meta What are the rules on adding new APIs to CoreFX? I saw this: https://github.com/dotnet/corefx/issues/1017#issuecomment-107752252. > To expose the RuntimeEnvironment class, it requires updation to the desktop api, which will not come to effect until next desktop release. Hence, the portable version cannot be released, before the desktop 4.6.1 is released, to ensure this contract works on all platforms, which is the same problem we had with PlatformID, we want to decouple ourselves from desktop dependencies and be more quick with releases. What are the rules that are proposed for updating .NET Core? There are at least a few scenarios: - Adding new members on a type that exists in the .NET Framework. - Adding new types that represent a similar concept that exists in the .NET Framework - Adding new types (new concepts) that do not exist in the .NET Framework. Ideally, we could update .NET Core at the pace we want. Is the issue that we might add one new member to a type that is represented in contract foo and doing so would make contract foo incompatible with .NET Framework vLatest? /cc @Priya91, @terrajobst, @davidfowl 1894 area-System.Net The message or signature supplied for verification has been altered "Hello.

EVP_CIPHER_CTX_new should allocate the memory and call (OpenSSL) EVP_CIPHER_CTX_init, and have a well-defined free. If gymnastics are required for checking this in, a followup issue to use the new method should be filed. If the native library has moved to dotnet/corefx by the time this is done, then the managed code to consume it should potentially be part of the same change. 1965 area-System.Security AES DecryptorReusabilty.TestDecryptorReusability test is failing on Unix ``` 14:20:43 Finished: System.Security.Cryptography.Encoding.Tests 14:20:43 System.Security.Cryptography.Encryption.Aes.Tests.DecryptorReusabilty.TestDecryptorReusability [FAIL] 14:20:43 Assert.Equal() Failure 14:20:43 Expected: Byte[] [20, 48, 113, 173, 237, ...] 14:20:43 Actual: Byte[] [20, 48, 113, 173, 237, ...] ``` 1967 area-System.Collections [Proposal] IImmutableSet.Union should handle duplicates like ISet.UnionWith The [`ISet.UnionWith`](https://msdn.microsoft.com/en-us/library/dd411713.aspx) method is documented to handle duplicates as follows: > ``` cs > void UnionWith(IEnumerable other) > ``` > > Any duplicate elements in _other_ are ignored. The [`Enumerable.Union`](https://msdn.microsoft.com/en-us/library/vstudio/bb341731.aspx) extension method documents an even stronger condition: > ``` cs > public static IEnumerable Union(this IEnumerable first, IEnumerable second) > ``` > > When the object returned by this method is enumerated, `Union` enumerates _first_ and _second_ in that order and yields each element that has not already been yielded. The `IImmutableSet.Union` method appears to provide the same functionality as the above method, but does not specify the behavior of the result with respect to duplicate elements. In the current implementation of `ImmutableSortedSet`, the `Union` operation behavior varies depending on the relative size of the `this` and `other` sequences. This could be confusing for users expecting the elements of the `this` sequence to take precedence. I propose defining the behavior with respect to duplicates partially (to match `ISet.UnionWith`) or fully (to match `Enumerable.Union`), and updating the implementation of `ImmutableSortedSet` to follow the new behavior. 1973 area-System.Collections Please add interface IReadOnlySet and make HashSet, SortedSet implement it "Since `IReadOnlyList` was added the parity between sets and lists has declined.

This is related to https://www.github.com/dotnet/corefx/issues/1813, but a targeted fix for that issue would not fix this, and vice versa. 1991 area-System.IO Improve memory allocations of DeflateStream We use GZipStream to handle the data sent on the wire to a WebAPI with both big and small requests. The allocation stress is more evident with small packages though. On a sample of 60 seconds in an stress test we measured that System.IO.Compression.OutputWindow.ctor() and System.IO.Compression.DefrateStream.ctor() would be consistently in the top 5 allocators. Between the two 1.8Gb in allocations in 60 seconds. The root is that DefrateStream will create on every construction (1 per request) an Infrater (https://github.com/dotnet/corefx/blob/master/src/System.IO.Compression/src/System/IO/Compression/DeflateStream.cs#L62) and the Infrater will also build an OutputWindow (https://github.com/dotnet/corefx/blob/master/src/System.IO.Compression/src/System/IO/Compression/OutputWindow.cs). Which in turn will allocate 32Kb to use as a buffer for each request. Reusing those buffers and/or OutputWindow would aleviate a lot the allocation stress GZipStream causes when used in small streams contexts like Web APIs. 1993 area-System.Security [Feature] Finish X509Certificate support for Unix The current Unix X509 code was to the level that it needed to be to allow presenting an SSL wire cert for verification.

So when the FindByInvalidThumbprint test runs (and searches for ""Nothing"") that is the same as searching for `new byte[] { 0xFF, 0xFF, 0xFF, 0xFF }`. A more marginal case would be that ""00FZ00"" becomes `{ 0x00, 0xFF, 0x00 }`, which could cause some interesting wrong matches for things like FindBySerialNumber. As the Find API returns no matches (vs throwing exception) on invalid input, the Decode probably should be redone to TryDecode, giving the helper routines the knowledge that they should just return no match. " 2009 area-System.Security SyncRoot and IsSynchronized on X509 collections should be explicitly implemented (private) I noticed that [`X509ChainElementCollection`](https://github.com/dotnet/corefx/blob/master/src/System.Security.Cryptography.X509Certificates/src/System/Security/Cryptography/X509Certificates/X509ChainElementCollection.cs#L24-L32) and [`X509ExtensionCollection`](https://github.com/dotnet/corefx/blob/master/src/System.Security.Cryptography.X509Certificates/src/System/Security/Cryptography/X509Certificates/X509ExtensionCollection.cs#L28-L36) implement `ICollection`'s `SyncRoot` and `IsSynchronized` properties implicitly (public).

It might make sense that XxxPtr table is smaller than the Xxx table. But I don't see how it can have more rows.

Though not quite as common as concatenating sequences, I have been surprised at how often this need arises. Doing this inside of an expression today is not straightforward; the best equivalent that I have found is far from ideal: ``` sequence.Concat(Enumerable.Repeat(singleValue, 1)) ``` I propose adding Prepend and Append extension methods to Enumerable to fill this need. ## API ``` public static class Enumerable { public static IEnumerable Append(this IEnumerable source, T value); public static IEnumerable Prepend(this IEnumerable source, T value) } ``` ## Usage ``` optionalValues.Prepend("""") ``` " 2076 area-System.Linq Sorting sequences ## Summary There are two scenarios where the existing Enumerable OrderBy methods are not ideal: - When sorting a sequence of comparable values (e.g. ints). In this case an identify function must be provided as the key selector: `ints.Sort(x => x)` - When sorting on something other than a single key, an identity function must be provided to select the element as the key, AND an instance of IComparer must be provided, which is at odds with the majority of LINQ methods which take functions (and are therefore easier to use with lambda expressions): ``` using NodaTime; using NodaTime.TimeZones; ... IEnumerable tzs = ...; var tzEqComparer = new ZoneEqualityComparer(); tzs = tzs.OrderBy(x => x, Comparer.Create((tz1, tz2) => tzEqComparer.Equals(tz1, tz2) ? 0 : tz1.Id.CompareTo(tz2.Id)); ``` I propose adding various overloads of Sort to address these situations. The name Sort is chosen specifically to distinguish these methods, which do not take a key selector, from the OrderBy methods, which do. If this is not considered an important distinction, the names could be changed to OrderBy without colliding with the existing methods. ## API ``` public static class Enumerable { public static IOrderedEnumerable Sort(this IEnumerable source) where T : IComparable public static IOrderedEnumerable Sort(this IEnumerable source, IComparer comparer) public static IOrderedEnumerable Sort(this IEnumerable source, Comparison comparison) public static IOrderedEnumerable SortDescending(this IEnumerable source) where T : IComparable public static IOrderedEnumerable SortDescending(this IEnumerable source, IComparer comparer) public static IOrderedEnumerable SortDescending(this IEnumerable source, Comparison comparison) public static IOrderedEnumerable ThenSort(this IOrderedEnumerable source) where T : IComparable public static IOrderedEnumerable ThenSort(this IOrderedEnumerable source, IComparer comparer) public static IOrderedEnumerable ThenSort(this IOrderedEnumerable source, Comparison comparison) public static IOrderedEnumerable ThenSortDescending(this IOrderedEnumerable source) where T : IComparable public static IOrderedEnumerable ThenSortDescending(this IOrderedEnumerable source, IComparer comparer) public static IOrderedEnumerable ThenSortDescending(this IOrderedEnumerable source, Comparison comparison) } ``` ## Usage ``` ints.Sort() ``` ``` using NodaTime; using NodaTime.TimeZones; ... IEnumerable tzs = ...; var tzEqComparer = new ZoneEqualityComparer(); tzs = tzs.Sort((tz1, tz2) => tzEqComparer.Equals(tz1, tz2) ? 0 : tz1.Id.CompareTo(tz2.Id)); ``` ## Questions 1. The generic restriction to IComparable is not necessary if the implementation will delegate to OrderBy with an identity function (although there are other potential implementations). However, even if not strictly necessary, it clearly expresses the intent of the method. Is there a downside to keeping it? 2. Overloads that take an IComparer are included for parity with OrderBy. Between the two, I prefer the overload that takes the Comparison, since converting an IComparer into a Comparison is more straightforward than going the other way. However, I am not aware of the rationale behind using IComparer instead of Comparison in the OrderBy methods. We should consider whether the same rationale applies to Sort, or whether it might make sense to remove the IComparer overloads to reduce the API surface. 3. Should the OrderBy methods have overloads added that take Comparison for parity? Or is there something about the usage pattern of selecting a key that makes it less likely that a comparison function will be provided inline? (This is the inverse of question 2). 4. What about Queryable? 2077 area-Serialization Support JSON-LD in DataContractJsonSerializer There is an issue raised by dotnet/wcf#28 requesting support for JSON-LD.

If there is no issues I will follow to clean up this directive and unused code. @SGuyGe @zhenlan @roncain @shmao 2085 area-Serialization Fix serialization of generic queue to align with NetNative Generic queue is serialized differently in NetCore compared to NetNative since it skips the queue's _syncRoot property of type object. This change is to fix the behavior when serializing property of type object in general. As Serialization of generic queue on desktop is controlled with Serializable, NonSerialized attributes, which are not available in NetCore, this results in a different load compared to desktop. I have verified that cross platform serialization/deserialization works fine. cc: @SGuyGe @zhenlan @shmao 2093 area-System.ComponentModel Can `sealed` modifier be removed from `DisplayAttribute`? I'm redirected here from MVC6 repo (https://github.com/aspnet/Mvc/issues/2706). In MVC6 we are meant to use `DisplayAttribute` to define human readable texts for model's properties. In earlier versions, MVC was using `DisplayNameAttribute` and it could be inherited, so developers were overriding it and customizing texts, messages, labels on the air (like translating or formatting them etc.). Now MVC6 uses .NET's `DisplayAttribute` for this use and it's sealed and unfortunately we are restricted here now. Is it possible to remove the `sealed` modifier from this attribute? So I think the frameworks using this attribute will be more customizable. 2101 area-System.Reflection Add TypeInfo.IsEquivalent(TypeInfo) to CoreFx It is currently not possible to write a library that compares types correctly (considering NoPIA interface unification) and that works on both Desktop CLR and CoreCLR without calling Type.IsEquivalentTo via Reflection on Desktop. 2102 area-System.Text Consider adding StringBuilder.AppendEncoded(Encoding encoding, byte* bytes, int byteCount) In general Encoding APIs don't compose well with other fundamental APIs without allocating temporary blobs/strings in between. 2103 area-System.Globalization How should we handle default data for Globalization tests? "In .NET Core, a large portion of the implementation of our globalization code is built on-top of OS primitives. which we don't control. Globalization data changes frequently and updates to the data can break unit tests. Some examples of changes we've had problems with in the past: 1. Collation data changing across releases and platforms, causing sorting tests to break. 2. Locale data changing (e.g a locale adopts a new currency symbol) causing test breaks. 3. Casing data changes, breaking ToUpper/ToLower tests. 4. Different platforms supporting different version of IDNA. In our internal tests, we've taken a few approaches to solving these problems: 1. Implementing another set of (hopefully lightweight) P/Invokes on-top of OS Functions and using them to generate the expected data at runtime. 2. Disabling specific tests (by hand) on specific platforms or changing the expected data for a specific platform via a runtime test. 3. Encoding metadata about the version of Unicode a platform supports and the version a test requires and skipping tests if they don't match. As I start to open source more of our collation tests, I'm running into problems where we depend on support libraries that implement the OS behavior from (1). It's not clear to me that adopting this is the right long term approach. There's a bunch of platform specific code in these support libraries which will also have to be brought cross platform. The library also contains a fair amount of logic itself. My general preference would be to do something like the following: 1. Use XUnit data driven tests (i.e. `[Theory]`) to write tests that decouple the implementation of the test from the input data. 2. Using `[MemberData]` control the set of inputs that flow to each test based on runtime platform detection. For example, consider something like the following: ``` csharp [Theory] [MemberData(""CompareToData"")] public static void CompareTo(string localeName, string left, string right, int expected, CompareOptions options) { CompareInfo ci = CompareInfo.GetCompareInfo(localeName); int result = ci.Compare(left, right, options); Assert.Equal(expected, Math.Sign(result)); } public static IEnumerable CompareToData { get { yield return new object[] { """", ""Works Everywhere"", ""WORKS EVERYWHERE"", 0, CompareOptions.IgnoreCase }; if (PlatformDetection.IsWindows) { yield return /* ... some set of data that only works on Windows ... */; } } } ``` Will will also need the ability to run certain cases on a specific version of Windows (since behavior changes between versions) or a specific version of ICU. However, I would expect the general shape of the tests would remain the same (`[Theory]`'s + `[MemberData]`'s) and the only thing that would differ would be the filtering we use when deciding if we include a test case in the MemberData. I think there are two downsides with this approach: 1. Bringing a new version of an existing platform online is more expensive. Since we no longer call to the OS to get our oracle data, we will need to investigate test failures to understand if there are product bugs or simply changes in OS algorithms. 2. `[Theory]` is slower than simply having a ton of a `Assert`'s for different cases (or doing a loop) in one `[Fact]`. The major slowdown was in test discovery. As an experiment (and to ease some debugging for some work I was doing), I ported the [NormalizationAll](https://github.com/dotnet/corefx/blob/master/src/System.Globalization.Extensions/tests/Normalization/NormalizationAll.cs) test to use `[Theory]` and the test which used complete very quickly now take about a minute to run (There are 72K test cases, XUnit reports that it took 10.6 seconds to execute the tests (compared to 1.5 when using a loop), but that didn't count the ~50 seconds to discover the tests). It also appears that much of this time is spent even if the tests would not be run (e.g due to `[ActiveIssue]` or `[OuterLoop]`). Ideally this could be fixed, but I am not sure, naively it feels weird that you pay an order of magnitude penalty in test execution because of Theory, but I have not dug into the internals of xUnit. The mitigation here is to not use [Theory] when doing so would generate tons of cases, I guess, and just do a loop ourselves (ideally still over something like a member data API). I'm not sure if these are dealbreakers or not. (2) seems bad, but is a general problem for us adopting Theory for large data-sets, which seems to be a a problem for more than just globalization. I also really hope that we can adopt something like this, since it makes reporting for data driven tests so much nicer. I'm interested in what @stephentoub and @tarekgh think here. Does the pain of OS Data updates make the OS Wrapper library the right approach, even if it brings in a lot of extra code and causes a another large amount of work when we bring up a new platform? Is the fixed data + filtering approach a better long term direction? Do we need both for some reason? " 2106 area-System.Security Proposal: Add Ed25519 and Curve25519 Algorithms to System.Security.Cryptography The System.Security.Cryptography namespace contains several commonly used cryptographic algorithms. I propose the addition of two commonly used algorithms which are currently missing: - **Ed25519** is an implementation of an _Edwards-curve Digital Signature Algorithm_. - **Curve25519** is an algorithm designed to be used with _elliptic curve Diffie-Hellman (ECDH) key exchange algorithm_. Both are based on the same elliptic curve. Many open source projects (e.g. OpenSSH, OpenBSD) seem to prefer this elliptic curve for use in elliptic curve cryptography (ECC). It is therefore beneficial to have these algorithms implemented in CoreFX. The two algorithms should be included in the existing classes in the `System.Security.Cryptography` namespace, but it must be possible to explicitly ask for the usage of these algorithms. 2108 area-Meta Where should ref docs and associated samples be stored?

The algorithm seems to make no use of [GetHashCode](http://msdn.microsoft.com/en-us/library/vstudio/ms132155.aspx).

Other structs in the Framework do _not_ take this care (such as `DateTime`, `Nullable`, or `System.Int32`), despite [claiming to be thread-safe in MSDN documentation](https://msdn.microsoft.com/en-us/library/System.DateTime%28v=vs.110%29.aspx). Should we take the same care for the other structs? The community [has been fascinated](http://stackoverflow.com/questions/30957211/what-advantage-is-there-to-storing-this-in-a-local-variable-in-a-struct-method/30957262) by the pattern in `ImmutableArray` and brought up that it might make sense to spread it around more. 2121 area-System.Reflection Implements fast document name comparison, parsing, and general case-insensitive string comparison 2124 area-Infrastructure We need a way to run tests on different runtime We need a way to choose between different platforms when running tests.

It is currently inconvenient to create these pairs as one needs to specify type arguments to the constructor. A simple factory method would make it more succinct since the C# and VB compilers can usually infer the generic arguments: ``` C# public static class KeyValuePair { public static KeyValuePair Create(K key, V value) { return new KeyValuePair(key, value); } } ``` this pattern is already used by ImmutableArray. 2129 area-Serialization Fix Jit assert failure in struct serialization tests due to missing cast This change fixes 3 struct serialization test Jit assert failures due to missing cast in IL generated code. cc: @zhenlan @SGuyGe @shmao 2135 area-Infrastructure Reenable build multithreading once dnx issues are fixed Once dnx concurrency issues are fixed, reenable project multithreading.

We have Distinct, Except, Intersect, Union, etc. Often it is required, though, to base the set operation on some key. OrderBy can do that for example. I request that the following methods be added: - DistinctBy (pick the first element deterministically for each key) - ExceptBy (return all items of the first sequence that do not have a matching key in the second) - IntersectBy (return the first item in a.Concat(b) for each unique key where the key appears in both collections) - UnionBy (return the first item in a.Concat(b) for each unique key) - MaxBy/MinBy The set operations need to deal with duplicate keys in a sensible way. I have added to that list my idea for how to do that in sane and well-defined way.
Another commonly required helper method is one that splits a sequence into chunks of a fixed size: ``` static IEnumerable> AsChunked(this IEnumerable sequence, int chunkSize) ``` This is useful for many things, for example: - Split a list into pages - Make AsParallel operate on coarser items by feeding it chunks - If you want to save a huge stream of items to files you can use this to split the sequence into one chunk per file - Request rows from the database in chunks of 1000 IDs This requirement comes up on Stack Overflow a lot and there is no built-in way to do it. The chunks should be drawn lazily. In fact the items of each chunk should be lazy as well. This allows for very big chunks such as 1 billion items per chunk. Maybe we need two variants: 1. `IEnumerable> AsChunkedLazy` 2. `IEnumerable AsChunkedEager` The second one would be easier to handle for consumers. The first one requires more disciplined use because each chunk must be enumerated at most once and the chunks must be enumerated in order. This is required for an efficient streaming operation. 2149 area-System.Net Initial open source WinHttpHandler This is the initial open sourcing of the System.Net.Http.WinHttpHandler package.

This is different from what we do for OSX and Linux (where we use the 64 bit version of the runtime built from [dotnet/coreclr](https://github.com/dotnet/coreclr)). I believe because of this we also don't get coverage on any of the RyuJIT specific optimizations around Vectors as part of our unit tests. I think it would be ideal if we also ran tests on a 64 bit runtime and it corresponded to some LKG build from [dotnet/coreclr](https://github.com/dotnet/coreclr). /cc @stephentoub 2151 area-System.Reflection Fix incorrect MethodSpec signature header check There was some confusion in untested code around ELEMENTTYPE_GENERICINST vs. CALLCONV_GENERICINST cc @tmat 2152 area-System.Xml [Perf] Fix XmlDocument/XPath to properly compare strings by ref "XmlDocument/XPath when comparing namespaces it uses fixed string object (from private class defined in XmlConst.cs).

This is a [feature request for our DNX runner](https://github.com/xunit/dnx.xunit/issues/42) which we cannot satisfy without some form of XSL-T support.

There are a couple of different parts to be done: - OCSP (Online checks) - CRL fetching (Online checks) - CRL caching (Online/Offline checks) - CRL cache refresh - Using the CRL during chain building 2204 area-System.Security Figure out a strategy for X509VerificationFlags on Unix Because OpenSSL reports back only the first error it finds, the Ignore\* flags can't be used to disregard error codes coming back. Whatever flags cannot be supported should be changed to a PlatformNotSupportedException. 2207 area-System.Security Add support for additional LocalMachine X509Stores on Unix, or throw PlatformNotSupportedException LM\Root, and to a lesser degree LM\CA, are populated from a system directory.

Many (technically all) of the operations can be emulated in CPU when not available with specific optimizations for the target platform or even have the ability with specially crafted if-then-else optimizations. That would allow to even switch to an entirely different algorithm without any runtime impact (if properly done at the jitting phase). 2210 area-System.Security Consider multi-threading implications on the OpenSSL ERR_get_error queue. OpenSSL compiled with OPENSSL_FIPS seems to have a single static ERR_STATE object for the process. The default appears to be set up for providing the capabilities for stack-per-thread, but OPENSSL_thread_id() appears to return the process ID, not the thread ID. The mainline seems to be served by `OPENSSL_set_id_callback` to something returning a thread ID; and lightup for FIPS could try invoking `int_ERR_lib_init`, which resets the library to the non-FIPS way of error management (though that theoretically has FIPS implications...). 2217 area-System.Text UTF8Encoding should support encoding/decoding of unpaired surrogates "According to RFC 3629 encoding/decoding unmatched surrogates should be disallowed: ""The definition of UTF-8 prohibits encoding character numbers between U+D800 and U+DFFF, which are reserved for use with the UTF-16 encoding form (as surrogate pairs) and do not directly represent characters."" However, this hasn't been followed by real world encoders/decoders. For example, the ECMA-335 standard encodes string arguments of custom attributes using UTF8 and the compilers allowed unpaired surrogates in the attribute argument. Another example is PDB - the file paths in PDB are stored as UTF8 encoded strings and unpaired surrogates are also allowed. The same for values of local string constants (e.g. `const string surrogate = ""\ud800""`). To avoid breaking changes Roslyn needs to allow unpaired surrogates in the above cases and the MetadataReader should also use a variant of UTF8 encoding that is able to decode them. Currently Roslyn has a custom implementation of UTF8 encoder originating from CCI. In general, it seems that pragmatically a UTF16-UTF8 round-tripping is desirable in certain scenarios and UTF8Encoding should support it. I propose to add a constructor to UTF8 Encoding that takes a bool allowUnpairedSurrogates (false by default) that can be used by both Roslyn and MetadataReader.

However, in some cases the `IEnumerable` produced by a call to `Cast()` will in fact be an array of another type that can be converted on the fly by the implementation of `GetEnumerator()`. This works well in many cases and is a valuable optimisation (rather than going through `CastIterator`) but if `ToArray()` is called on it, the result is an `ArrayTypeMismatchException` that would not be expected by the user, especially since code might call `ToArray()` without knowing that `Cast()` had been used, or pass the result of `Cast()` to a method, not knowing that `ToArray()` would be used. In particular this happens if you `Cast()` an array of one `enum` type to another `enum` type. 2246 area-System.Net HttpClient not thread Safe Hi, Recently I noticed HttpClient, FtpClient (maybe SMTPClient I have to check) are not thread safe when Scheme is set https.

The existing 4.5 Array.sort is implemented with intro sort. While this has reasonable behavior, it effectively has the same number of comparisons regardless of input size. This number of comparisons is (as expected) around `n * log_n`. While this is acceptable for random inputs, it is unfortunately much slower for nearly-sorted inputs. More recent algorithms (like TimSort) can provide massive improvements here, sorting nearly-sorted lists with a nearly linear number of comparisons. For code-paths where sorting is expensive, and where comparisons are not cheap, a better sort algorithm built into the Fx would be appreciated. Whether or not this becomes the default is up to you. But providing it as an option would still be a huge boon. Note: this hits Roslyn+TypeScript. We often produce trees (i.e. for tagging) from nearly sorted data. There may be hundreds of thousands of elements in this data. Being able to sort in near-linear time means we can then build our trees in linear time. With data sets this large, the difference between `n` and `n log n` is actually quite significant. 2254 area-System.Runtime Provide ways to parse sections of a string, not an entire string. Right now .Net provides lots of ways to convert strings to other values. For example `Int32.TryParse`. This is fine if you are starting with a string, but it's very suboptimal if you have a larger string, and are trying to parse out a piece of it. You are forced to first create a substring, and then parse that. This adds GC pressure to the system and can be a large perf impact. It would be very beneficial to have overloads of these functions that took a start+length. Alternatively, if there were some sort of struct representing a piece of a string, that could also work as well. Right now this impacts TypeScript greatly. We have to marshal data from JavaScript to .Net. This comes in as a string to us, which we then need to parse out into actual values (like ints). We are forced to either send tons of strings over (not ideal), or send one big string over that we then are forced to break into tons of small strings. Right now we've worked around this by hand-writing our own Int32.Parse that can work on subsections of a string. But this is non-ideal and would really be served inside the runtime so everyone could benefit. This is a place where really ony the runtime could implement this thing. There is so much complexity around string parsing (even just for ints), with things like FormatSpecifiers and whatnot, that trying to duplicate it in another library would be unfeasible. 2255 area-System.Linq IntersectIterator not optimized to exit early In System/Linq/Enumerable.cs, the `IntersectIterator` method will iterate over all of the items of `first`, even if the `set` created by `second` is empty.

Windows will follow the AuthorityInformationAccess record and attempt to download any intermediate certificates as part of building the X509Chain, we should enable this for the Unix platforms as well, to maintain feature parity. **Important**: Downloaded self-signed certificates are NOT considered trustworthy, and they need to make the chain report as not valid (unless root trust was bypassed). Also important: Any testing for this should be [OuterLoop], because it would depend on the network. 2278 area-System.Collections Rename Validation to Microsoft.Internal.Validation "The C# (and possibly VB compiler) will match the top-level namespace `Validation` in `System.Collections.Immutable` even though it only contains internal types. This prevents customers from using a type named `Validation` in their code. Specifically, assume a customer has defined the type like this: ``` C# namespace Support { public static class Validation { public static bool IsValid(string x) { return true; } } } ``` Consuming this type stops working when `System.Collections.Immutable` is referenced: ``` C# using System; using System.Collections.Generic; using System.Linq; using System.Text; using Support; namespace ImmutableTest { public class Experiment { // With out Immutable included, the below works just fine. // Once I include immutable, Validation, which was really // Support.Validation, but was found because of the using // statement above, it starts to fail showing that it can't // find IsValid in the namespace Validation. public void Test1() { Validation.IsValid(""AS""); } public void Test2() { Support.Validation.IsValid(""AS""); } } } ``` According to @jaredpar this behavior is by-design: > This behavior is by design for C# at least. A simple name lookup will prefer matching namespaces over types (section 7.5.2). I didn’t check the VB spec but it almost assuredly has the same design here. In order to avoid that conflict, we should rename the `Validation` namespace to something like `System.Validation`.

The missing standard implementations in BCL are required by many consumer scenarios, for which .NET applications rely on [third party libraries](http://stackoverflow.com/a/1533114/863980). One of the chief scenario is Content Query Web Part (CQWP) in SharePoint, where the users' XSLT code can be drastically minimized if v2 is supported by `System.Xml.XPath`. As for most parts, there are backward compatibility fallbacks available, that is; the code written in XSLT 2 precisely, can be expressed verbosely in XSLT 1 and since so forth. ### Pitfalls Unfortunately, (besides the existing third-party libraries' APIs) I do not have an off-hand -- concrete -- method list to propose, as it requires further brain-storming on whether to auto-select processor based on the input or to explicitly separate the namespaces (`System.Xml.XPath2` and `System.Xml.XPath3`). The point to ponder being; since the sub-languages XPath 2 and XPath 3 intrinsically facilitates backward compatibility modes, see [XPath 2: J.1.3 Backwards Compatibility Behavior](http://www.w3.org/TR/xslt20/#backwards-compatibility-behavior) and [XPath 3: 3.10 Backwards Compatible Processing](http://www.w3.org/TR/xslt-30/#backwards), should the API be any different than the existing one and let consumers select the standard mode? 2315 area-System.Drawing Primitive Color Type for .NET Core ## Primitive Color Type for .NET Core The previous discussion of primitives showed that color discussion should expand into a separate issue. The primitive discussion was started because many customers wanted to move to the .NET Core, but were blocked by the lack of System.Drawing primitives there. There was much discussion and internal debate over defining Point, Rect, and Size and much of that was fueled by scenarios that you guys cited in the previous primitives issue. (Thank you!) Here we are looking for additional scenarios to discuss the advantages of creating a new Color type for the cross-platform .NET Core Graphics API. Feel free to repost your two cents from the previous primitives issue. Thanks for your input! Topics of Interest: (This is where providing scenarios would be awesome) 1. Naming (ColorRgba, sRGB) 2. Different Color Formats (int8 bits, float 16 bits, float 32 bits, alpha or not) Color4F, Color3F, Color4F 3. Color Spaces (conversion issues) 4. Gamma vs Linear 5. Extension Methods (vector operations: lerp, scaling, conversions: from RGB to HSB and reverse, from vectors) 6. Semantic parity with CSS 7. WinRT Compatibility Limit Scope: KnownColors will not be brought over as they don’t always translate well into the cross-platform world depending on the hardware so let’s focus our discussion on defining the Color object for now. 2316 area-System.Linq LINQ/PLINQ `Sum(int)` does not loft to long for intermediate calculation. Currently, even if the total value of elements in a collection falls within the range of the type, LINQ/PLINQ will throw errors if the _running_ total would overflow. That is: ``` new[] { int.MaxValue, int.MaxValue, int.MinValue }.Sum() ``` ... currently throws an overflow exception because of the first two items, even though the total is within range (`int.MaxValue - 1`). It may be beneficial to loft to long for the intermediate cancellation, similar to how float lofts to double (although that particular one is more about an accurate result, not exactly overflow). 2317 area-System.Linq Make IOrderedEnumerable covariant Today, I was trying to convert an `IOrderedEnumerable` to an `IOrderedEnumerable`, but the compiler responded with an error. Looking into the interface, there doesn't seem to be any reason why it can't be [covariant](https://msdn.microsoft.com/en-us/library/dd799517%28v=vs.110%29.aspx), and in fact when I copied and pasted the interface and changed the class signature to `IOrderedEnumerable` everything compiled fine. Can we change this in the BCL, as well? There doesn't seem to be a reason not to. Sidenote: This **may** cause some [breaking changes](http://stackoverflow.com/a/2843563/4077294), but as the post points out this has already been done with `IEnumerable` on a greater scale. ### Proposed API ```C# // Updates existing interface in being covariant. public interface IOrderedEnumerable : IEnumerable { // Existing member IOrderedEnumerable CreateOrderedEnumerable(Func keySelector, IComparer comparer, bool descending); } ``` *(edited by @terrajobst to include the API write-up from @JonHanna)* 2320 area-System.Reflection (api review) IL Object Model "@terrajobst From the recent [API Review 2015-07-08](https://github.com/dotnet/apireviews/tree/master/2015-07-08-ildasm-and-drawing) **IL Object Model** **Observations** - Implement a custom object model. - use [Mono's Cecil](https://github.com/jbevain/cecil) implementation. **Parsing** - From the byte stream - From the text representation. **Output** - Byte stream - Text Representation The issue here I see is that some instructions have ""pointers"" to data embedded into the assembly bytes. A very common one is `Strings`. So you're going to need an object to represent that so that construction of the output bytes is correct. **IL Labels** These point to data objects that encoded into the assembly. - Strings being a common one. - `switch` uses them as jump targets. A benefit of an IL object model, is that you could get an IL representation of a method, without doing a full compilation. **Targeting** For example Roslyn should ""compile"" to an IL Object model, first. which then permit for further diagnostic analysers (or an optional layer). On the produced IL For example:- A analyser to help minimise Boxing operations. you'll should be able to trickle that information back to source-code level. **Compilation** The last stage would ""Compilation Targets"" for various architectures eg. x86, x64,ARM and maybe even Typescript. This could be supplied as NuGet package. --- Side Note I implemented a partial implementation of an object model for IL [here](https://github.com/AdamSpeight2008/IL.Sarc) " 2321 area-System.Runtime ReadOnlyCollection interfaces. From MSDN: ``` public class ReadOnlyCollection : IList, ICollection, IEnumerable, IEnumerable, IList, ICollection, IReadOnlyList, IReadOnlyCollection ``` Suggested fix: ``` public class ReadOnlyCollection : IEnumerable, IEnumerable, IReadOnlyList, IReadOnlyCollection, ICollection ``` 2323 area-System.Linq Add Enumerable.ToHashSet We have `Enumerable.To*` methods for many common collections. `HashSet` is sorely missing. This feature should be cheap to implement and not be problematic in any way that I can see. Evidence that this feature is sorely missing: https://www.google.com/webhp?complete=1&hl=en&gws_rd=cr,ssl&ei=#complete=1&hl=en&q=.net+tohashset People are writing this method over and over again. 2324 area-System.Runtime Add common helper methods to the String class "The `String` class is missing some helper methods for string manipulation that are commonly needed. Of course it is possible for developers to add extension methods but that should not be required. here, I'll propose a list of methods that I think can be easily understood and are commonly required. The ordering of this list starts with the least controversial in my mind. 1. `bool Contains(this string str, string value, StringComparison comparisonType)`. We have no Contains version that takes a StringComparison. The workaround with `IndexOf` is awkward and feels like magic. 2. `Replace(..., StringComparison)`. Right now, `Replace` always uses `Ordinal`. 3. `string Left(this string str, int count)` as well as `Right`. `Left` is equivalent to `str.Substring(0, count)` but right is `str.Substring(str.Length - count, count)`. 4. `Truncate(int maxLength)`. This is not equivalent to Substring(maxLength) because Substring throws if the string is short. 5. `bool IsValidIndex(this string str, int index)` tests whether the argument can be used to obtain a character from the indexer. That sometimes comes in handy. Also `bool IsValidRange(this string str, int index, int count)`. Both can be useful for `Debug.Assert` assertions. 6. `string TrimPrefix(this string str, string prefix)` as well as `TrimPostfix`. It turns out that when working with externally generated strings (ETL processes) it is very common to need to remove a prefix. For example to get a JIRA issue number as an int you do `int.Parse(""PROJ-2317"".TrimPrefix(""PROJ-""))`. `Replace(..., ""PROJ-"", """")` is not equivalent and semantically wrong. The `TrimStart` method cannot be used here. Further helper methods would be `EnsurePrefix/Postfix`. 7. Some helpers to work on strings that might be null or empty. This comes up _all the time_. ``` public static string EmptyToNull(this string str) { return string.IsNullOrEmpty(str) ? null : str; } public static string NullToEmpty(this string str) { return str ?? string.Empty; } public static bool IsNullOrEmpty(this string str) { return string.IsNullOrEmpty(str); } public static bool IsNullOrWhitespace(this string str) { return string.IsNullOrWhiteSpace(str); } ``` 1. `SplitLines()`. Returns the string split into lines. Need to define how to deal with OS-specific line endings. Probably, this should just be `str.Replace(""\r"", """").Split('\n')` which seems to work for everything. I can see some issues with some of these proposals. They are not perfect but I want to get the discussion going. I feel the BCL has a blind spot here. The list certainly starts out with a few no-brainers. " 2327 area-System.Linq Make Enumerable.Any use the same optimizations that Count has (ICollection checks) `Enumerable.Count` uses `ICollection` and `ICollection` to perform a fast and allocation-free computation. `Enumerable.Any` should do that as well. The fact that `Any` does not check `ICollection` is pretty much the only downside to using `Any` vs. `Count() != 0`. This downside should be eliminated. This missing optimization causes confusion: - http://stackoverflow.com/questions/2989300/interview-question-any-vs-if-length-0-for-testing-if-a-collection-has-e - http://dpatrickcaldwell.blogspot.de/2011/08/enumerableany-vs-enumerablecount.html 2329 area-System.Threading Use a more dependable policy for thread pool thread injection As of .NET 4.5 the thread pool injects one thread per 0.5sec if it thinks more threads are required. This is a problem if the number of required threads suddenly increases. Example: A corporate ASP.NET website is idle at night. In the morning at 8AM 1000 people log on and start working. If the app is using let's say 100 threads starting from 8AM it will take like 50sec to create all of them. Until then there will be serious delays and timeouts. It is possible to construe arbitrarily bad scenarios. **Problem statement:** If thread pool load suddenly increases in IO bound workloads the pool is too slow to respond. This causes throughput and availability disruption. IO bound workloads relying on synchronous IO are common. Sudden workload changes are also common. Sometimes the workload can change due to a problem outside of the developer's control: A web service timing out or a database become slow. Let me stress that this causes service interruption. You can easily repro this yourself. Run a load test on an ASP.NET site with `Thread.Sleep(10000);`. The thread count goes up by 2 each second. Starting and shutting down a thread was benchmarked by me to be around 1ms in total. Threads are not really an expensive resource. The thread pool should be a lot more eager to create and destroy threads. 500ms delay to potentially save 1ms is not a good trade-off. **Easy fix:** I propose lowering the injection delay to 100ms. This reduces the problem given above by 5x. Ideally, the rate would be configurable. The shutdown delay could be lowered from 30s as well. Keeping an idle thread for 30000ms to save 1ms seems excessive. In this ticket I'm not that concerned with retiring threads, though. **Smarter, riskier fix:** The delay could depend on the number of threads in existence, the core count and the perceived pressure on the thread-pool. The injection rate could be: - 0ms delay for up to (ProcessorCount \* 1) threads - 50ms delay for up to (ProcessorCount \* 4) threads - Starting from that a delay of (100ms \* (ThreadCount / ProcessorCount \* someFloatFactor)). Reasoning: The more the CPU is oversubscribed the slower we want to inject. Maybe we need to have a maximum delay of 1sec. Or, the delay must rise sub-linearly (e.g. sqrt). Note, that the Windows Kernel has some thread pool injection heuristics that apply back pressure the more threads are in existence. This seems to work.

This is too low for almost any production load. I don't know what this low limit is supposed to accomplish. I understand the presence of _some_ limit as a safety measure but `2` is really never useful. Many developers have trouble with that: https://www.google.com/webhp?complete=1&hl=en&gws_rd=cr,ssl&ei=#complete=1&hl=en&q=site:stackoverflow.com+%22ServicePointManager.DefaultConnectionLimit%22 When somebody asks ""My HTTP requests are unexpectedly slow"" the default answer is ""DefaultConnectionLimit = int.MaxValue"" and this solves the problem in about 80% of the cases. This is strong evidence that the default should be changed. This is an ongoing cause for trouble and surprise. There are three choices that I can think of: 1. Unlimited. ASP.NET has chosen this (`SetAutoConfigLimits`) presumably for good reasons. I think this is the least surprising choice. When a developer says `new WebClient().Download(...)` he expects the request to be sent right away. The dev is responsible for ensuring a sane degree of concurrency. he can use `SemaphoreSlim` or the service point infrastructure for that. 2. A constant factor on the CPU count of the machine (e.g. 10). Pro: This scales up with the size of the machine. Con: It might be a low-CPU (e.g. 2) machine that does little processing but relays it's request to some backend REST service that does the heavy lifting. 100 outstanding requests per CPU would not surprise me at all in such a situation. The benefits of async IO would be throttled. 3. `1`. At least this would make developers very quickly aware that the limit exists and that they need to change it. Maybe the value of `2` follows from that reasoning. I consider this to be a weak choice that is going to be perceived as stupid (as is `2`). Another reason for ""Unlimited"" is that there should not be global limits but per-service limits. A .NET process often hosts many components each of which potentially take from the global limit. They could interact in surprising (and spooky) ways. I think the .NET Framework should pick the default value that has the least surprise and set this to `int.MaxValue`. Also, consider revising the default value of `Expect100Continue`. I believe there is not a single developer in the world who expects each `POST` request to be performed twice by default. I do not know a single case where this was ever deemed useful. Disabling this behavior would entail, I believe, low compatibility risk. (See http://stackoverflow.com/search?q=Expect100Continue) " 2335 area-System.Collections Improve ConcurrentBag GetEnumerator performance Currently `ConcurrentBag` `GetEnumerator()` causes list copying everytime enumerator is accessed eg. through `foreach`. This causes strain on the GC and list copying is also heavy operation on large bags. There should be alternative methods to enumarate the bag contents or implement `GetEnumerator()` so that it does not cause list copying. I have presented here 3 possbile solutions to this problem. **Solution 1)** Add `ForEach` method to `ConcurrentBag`: ``` CSharp public void ForEach(Func action) { // Short path if the bag is empty if (_headList == null) return; bool lockTaken = false; try { FreezeBag(ref lockTaken); ThreadLocalList currentList = _headList; while (currentList != null) // Go through thread lists { Node currentNode = currentList._head; while (currentNode != null) // Go through thead specific linked list { if (!action(currentNode._value)) return; // User wanted to break the operation currentNode = currentNode._next; } currentList = currentList._nextList; } } finally { UnfreezeBag(lockTaken); } } ``` `ForEach` function takes user specified `Func` delegate. This delegate takes the bag item as an argument and returns true/false depending on whether the user wants to continue or stop the enumeration operation. Here `ForEach` operation would lock the bag so that other threads would need to wait for the operation to finish. Therefore results of this operation would represent the bag as a moment-in-time snapshot. **Solution 2)** Add `GetEnumerableSlim` function: ``` CSharp public IEnumerable GetEnumerableSlim() { ThreadLocalList currentList = _headList; while (currentList != null) { Node currentNode = currentList._head; while (currentNode != null) { yield return currentNode._value; currentNode = currentNode._next; } currentList = currentList._nextList; } } ``` This would require an additional change to the internal class `Node`: ``` CSharp internal class Node { public Node(T value) { _value = value; } public readonly T _value; public volatile Node _next; // This needs to be marked as volatile public Node _prev; } ``` `GetEnumerableSlim` would enumerate the bag contents concurrently without locking the bag. The proposed implementation is thread safe from memory model point of view. The fields `ConcurrentBag._headList`, `ThreadLocalList._head` and `Node._next` are all volatile variables. Therefore all the threads always have the newest value available. In addition the `Node._value` reference/value is immutable. `GetEnumerableSlim` is safe to use concurrently. Of course here the enumerator would miss some of the concurrent additions/removals from the bag. Also enumerator could contain modification after the `GetEnumerator` was called. Similiar behaviour is also used in `ConcurrentDictionary`, `GetEnumerator` which may also miss some of the concurrent changes or contain new changes after the `GetEnumerator` was called. Therefore the `GetEnumerableSlim` is consistent with other concurrent collections and their enumerator implementations. (It would be intresting to know why `ConcurrentBag` `GetEnumerator` was originally implementeted so that it copies the bag contents to a list where as the other concurrent collections enumerate the contents concurrently eg. `ConcurrentQueue`.) **Solution 3)** Replace `GetEnumerator` with `GetEnumeratorSlim` implementation. This solution would totally eliminate the risk of performance degradation due to list allocations. But this might not be possible if the existing code relies on the fact that `GetEnumerator` returns moment-in-time representation of the bag. 2336 area-System.Globalization Rename tests in System.Globalization About 40-50% of the tests in System.Globalization do not have self descriptive names.

Currently only way to clear the bag is to call `TryTake` in a loop which is suboptimal in high concurrency applications: ``` CSharp T dummy; while(bag.TryTake(out dummy)) {} ``` Instead `Clear` method could be implemented so that the bag is emptied at once. Here is the proposed implementation: ``` CSharp public void Clear() { // Short path if the bag is empty if (_headList == null) return; bool lockTaken = false; try { FreezeBag(ref lockTaken); ThreadLocalList currentList = _headList; while (currentList != null) { currentList.Reset(); currentList = currentList._nextList; } } finally { UnfreezeBag(lockTaken); } } ``` Internal class `ThreadLocalList` needs new `Reset/Invalidate` method which sets the thread specific linked list _head and _tail to null as well as resets the counters. GC would then collect the non referenced linked list nodes. ``` CSharp internal void Reset() { _head = null; _tail = null; _count = 0; _stealCount = 0; } ``` `Clear` would lock the bag for the duration of the operation since it could cause undefined behaviour if other threads would access the bag while linked lists are being reseted. (Similarly ConcurrentDictionary also locks the dictionary when `Clear` is called.) 2339 area-System.IO Finish rewriting System.IO.FileSystem tests Finish rewriting the tests for System.IO.FileSystem and replacing the giant runTest() methods with individual [Fact]s and [Theory]s, replacing every instance of Console.WriteLine along the way. 2342 area-System.Xml XmlSchema in CoreFX Hi, Are there any plans to include XmlSchema in CoreFX? If not, is there any recommended way to manipulate schemas? Thank you. 2352 area-System.Runtime API Addition: Add generic Array.Reverse Add generic `Array.Reverse`. ## Rationale [`Array.Reverse`](https://github.com/dotnet/coreclr/blob/ef1e2ab328087c61a6878c1e84f4fc5d710aebce/src/mscorlib/src/System/Array.cs#L1570-L1606) is non-generic. It includes a fast path for a known set of primitive types via a call into the runtime (see [`TrySZReverse`](https://github.com/dotnet/coreclr/blob/4cf8a6b082d9bb1789facd996d8265d3908757b2/src/classlibnative/bcltype/arrayhelpers.cpp#L390-L424)), otherwise it falls back to slower code paths that involve boxing for value types. This is a significant performance cost for non-primitive value types, ~22x slower. Callers of `Array.Reverse` (like `List.Reverse` and `ImmutableArray.Builder.Reverse`) are affected by this performance issue. As a workaround, [`List.Reverse`](https://github.com/dotnet/coreclr/pull/1231) and [`ImmutableArray.Builder.Reverse`](https://github.com/dotnet/corefx/pull/2354) are being updated to not use the non-generic `Array.Reverse` method until the generic `Array.Reverse` method becomes available. Other non-generic methods on `Array` have generic counterparts like `Array.Sort` and `Array.Sort`, so this would just be making `Reverse` consistent with those. ## Proposed API ``` c# public abstract class Array : ... { // Proposed public static void Reverse(T[] array); public static void Reverse(T[] array, int index, int length); // Existing public static void Reverse(Array array); public static void Reverse(Array array, int index, int length); } ``` 2358 area-System.Net Initial commit of System.Net.WebHeaderCollection Just what it says on the tin. 2368 area-System.Net Address PR feedback for System.Net.WebHeaderCollection - Replace `HeaderParser` with `Func` - Make static fields `readonly` - Optimize `HeaderInfoTable` for allocation volume and remove the static constructor - Replace non-generic collections with generic collections 2369 area-System.IO Directory AccessTime, WriteTime, and CreationTime for nonexistent directories inconsistent "Labeld in code as ""//See VSWhidbey # 92050"" On Windows, Directory.GetAccessTime, Directory.GetWriteTime, and Directory.GetCreationTime (as well as their DirectoryInfo clones) will return default values when queried with a path to a nonexistent directory.

The fact of something being ordered can have implications for subsequent operations. The ordering Linq methods (`OrderBy`, `ThenBy`, etc.) operate first in O(1) time and space to make a promise of a subsequent O(n log n) sort in O(n) space. In many case though the following operation does not need all of the promised operation. `.OrderBy(λ).First()`, `.OrderBy(λ).First(λ)`, and so on request that a sequence be sorted (O(n log n) time/O(n) space) and then the first element taken (O(1) time and space) which is in total an O(n log n) time/O(n) space operation. However, it is reducible to the O(n) time/O(1) space operation of identifying just the item in question which can be done in O(n) time and O(1) space. As `First`, `Last` and their variants are particularly common with ordered sequences (in some cases not having any meaning without an order), I think this would be a worth-while optimisation. There are other optimisations available, such as all aggregate operations (`Sum` etc.) could be moved from O(n log n) time to O(n) time simply by extracting the source and ignoring the ordering, this may not be as common a case as to make it worthwhile. One could argue that the user should have not put the ordering in there in the first place, and while the cost of checking for an ordered source is slightly, it's not worth paying it on all aggregate operations to benefit a flawed case. `Reverse` is somewhere in the middle. It's reasonable to expect someone might construct an ordered sequence and then `Reverse` in some cases. It's got subtleties (one cannot simply reverse all `OrderBy` to `OrderByDescending` and vice-versa because `OrderBy` is documented as performing stable ordering in linq-2-objects and therefore reversed must have reverse source ordering on equivalent items) but wouldn't be hard, but it's less clear whether the pay off would be worth it. In the more useful cases of `First` etc. there is a fly in the ointment in that this would affect the number of times both key selectors for ordering and predicates for `First` etc. were called. As per #2349 this means side effects on `Func`s would be affected, though perhaps in a way that was less predictable to the user than with that issue anyway. As such, changing the behaviour of `First` in this case would require either a decision in favour of the change that issue would allow for, or a decision that this case was less harmed by such changing side-effects. In summary. I propose that `OrderBy(…).First(…)` and its cousins be optimised, and the trade-offs of optimising `OrderBy(…).Reverse()` be considered. 2402 area-System.IO DirectoryInfo.CreateSubdirectory(path) trims whitespace and returns parent directory "Calling directory.CreateSubdirectory(""whitespaces"") will return ""directory"" and create no subdirectory. ``` DirectoryInfo parentDir = new DirectoryInfo(TestDirectory); DirectoryInfo childDir = parentDir.CreateSubdirectory("" ""); Assert.Equal(parentDir.FullName + Path.DirectorySeparatorChar, childDir.FullName); ``` If newlines or tabs are used, then it throws as expected: ``` DirectoryInfo parentDir = new DirectoryInfo(TestDirectory); Assert.Throws(() => parentDir.CreateSubdirectory(""\n"")); Assert.Throws(() => parentDir.CreateSubdirectory(""\t"")); ``` The reason for this is that dir.CreateSubdirectory(path) essentially wraps around Directory.CreateDirectory(Path.Combine(dir.FullName, path)) which trims trailing whitespace (in this case ""path"").

On Desktop, if you specify a `null` value for the dictionary when constructing a new instance, an `ArgumentNullException` will be thrown. In corefx, it will attempt to create an empty instance of `IXmlDictionary` and assign that. It then straight away assigns the passed in `null` value to the dictionary effectively throwing away the empty dictionary that was created.

Investigate the CancellationToken for the Tasks 2. There are more comments made by Stephen Toub, which need to be taken care of. Refer to https://github.com/dotnet/corefx/pull/2197 2454 area-System.Threading Remove reentrancy by default from the TPL The TPL has a few performance features that cause reentrancy. Here are the ones I know of: 1. `TaskCompletionSource.SetXxx` can cause continuations to be executed synchronously. AFAIK this can happen both with or without `ExecuteSynchronously`. Starting with .NET 4.6 there is `RunContinuationsAsynchronously` to disable this behavior. 2. `Task.Wait()` and `Task.Result` can execute an unstarted CPU-based task inline. I do not know of any good workaround from the perspective of the caller of `Wait`/`Result`. Probably, `static Task.Wait(Task)` and related methods have the same problem. 3. `CancellationTokenSource.Cancel()` can execute registered notifications inline. 4. `TaskAwaiter` uses `TaskContinuationOptions.ExecuteSynchronously` if there is no synchronization context set. This forces reentrancy for whatever code completes the task being awaited. In all of these situations arbitrary code can run as part of invoking the respective TPL method. You might not control that code. There might be no way for you to know what code that is because you are writing a library. In big apps it might be architecturally impossible/unwanted to know what code might run. This is **arbitrary, non-deterministic reentrancy in multi-threaded code**. This is very dangerous behavior. Concrete problems (examples): 1. You might call `TaskCompletionSource.SetResult()` under a lock. Now, arbitrary code might run under your lock as well. This can **deadlock**. 2. That arbitrary code might perform blocking operations (e.g. IO). This will now run under your lock and **extend the lock hold time**. 3. The **invariants** of your data might be **temporarily broken**. Due to reentrancy other code can now observe invalid data. 4. **Monitor might fail to provide mutual exclusion** because `lock (x) { lock (x) { } }` does not block/deadlock. Inlining code onto the current thread opens the gates for any locks held by this thread. 5. You might run on a thread with **thread-dependent state** (STA thread, changed priority, deviating culture, `HttpContext.Current` null or not null, ...). This state is now exposed to arbitrary code. It is made available for mutation as well. **This is very unsafe behavior by default.** The number of questions that come up about it on Stack Overflow is noticeable. The bugs are insidious (racy). Please disable _all_ of these behaviors by default. Make unsafe performance features opt in. I doubt there will be compatibility impact from doing this because all of the behaviors above are, to my knowledge, non-deterministic. Completion callbacks should always be queued to the thread pool (or to any scheduler if specified) by default. The TPL should be safe by default. Reentrancy behavior should be: 1. Off by default. 2. Opt-in possible. 3. Overriding forced opt out by any side taking part (completing thread and registering thread). A library should be able to force-disable any of this, no matter whether it registers continuations or whether it completes tasks. This is a problem both for monolithic apps as well as for library authors.

Also some minor cleanup: I made some fields `readonly` that could be, and removed an unused using. Question about the existing behavior: If an exception is thrown during the copy operation, the source stream won't be disposed (if it can be disposed). Is this is by design?

If the parent directory of the source file is nonexistent, a FileNotFoundException is thrown. If the parent directory of the dest file is nonexistent, a DirectoryNotFoundException is thrown. Example: ``` File.Create(""test1"").Dispose(); File.Move(Path.Combine(Directory.GetCurrentDirectory(), ""test2"", ""test3""), ""test4""); // throws a FileNotFoundException File.Move(""test1"", Path.Combine(Directory.GetCurrentDirectory(), ""test2"", ""test3"")); // throws a DirectoryNotFoundException ``` The reason for this is that File.Move makes a call to ""InternalExists"" to check that the sourceFile exists in full and if it doesn't then a FileNotFoundException is thrown regardless of which part of the path caused the failure. Removing this check is simple and will leave path checking to the FileSystem implementation (which would be preferable), but it will need to be mirrored in the desktop as well or ignored/worked around on both.

The problem is that with a name like System.Threading.\* and with threads being a core part of many apps, people won't know (or care!) that UWP apps will lose out on that library because only Task is supported. The best solution is to implement Thread/ThreadPool for UWP so that people can use the threading model they're most comfortable with and what's most appropriate for the job. Forcing Task for UWP is counterproductive if it'll mean that UWP will lose out on many libraries that choose to use Thread anyway. When it comes to creation/consumption of .NET Core packages, right now ASPNet is the biggest driver. As much as we want people to use UWP, it's just smaller for now. That puts even greater pressure on UWP as library authors will either not know that Thread isn't available on UWP or care even if they do. .NET Core is supposed to be unifying the BCL and shielding libraries from platform/runtime differences.

The side effect of this change is that the FileSystemWatcher will now treat File.Move as a deletion. - Removed all tests from FileSystemWatcher that made calls to File.Move and consolidated them into a new file: FileSystemWatcher.MoveFile.cs. This new file separates tests into Windows and Unix categories and uses Theories to supply the input WatcherChangeType and whether a move should trigger an event for the given type. If we later decide to change the Unix behavior of MoveFile, changing the FileSystemWatcher tests will be a simple matter of flipping the boolean values for the affected tests. 2589 area-System.Net Update README.md for System.Net.Primitives System.Net.Primitives source code is now on GitHub.

Creating a DirectoryInfo with a short path, or creating it from a parent (eg: CreateSubdirectory, EnumerateDirectories,etc) returns just the directory name. On CoreCLR we are always trimming to just the directory name. I traced this behavior back to an IFDEF in the original code https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/IO/DirectoryInfo.cs#L639-L643. It seems that the original CoreCLR implementation (Silverlight/phone) hardcoded the short name. We should prefer the desktop behavior instead of the current. The current behavior is due to the legacy behavior of SL trying to sandbox the app. This is not a goal for CoreCLR and we don't have a back-compat burden for the current implementation. We also need to examine similar cases in other FileSystem types. 2635 area-System.Security Ensure that X509Certificates file tests run the gamut of supported formats.

" 2648 area-System.ComponentModel RangeAttribute with string constructor fails on various locales "`RangeAttribute(Type, string, string)` can be used to validate various types implementing `IComparable`. However, it does the conversion from the string parameters using the current culture, which is wrong. Simple repro: ``` Thread.CurrentThread.CurrentCulture = new CultureInfo(""fr""); new RangeAttribute(typeof(decimal), ""0.1"", ""0.9"").IsValid(123m) ``` fails with a `FormatException`: _0.1 is not a valid value for Decimal._ While in this sample the strings could be adjusted at runtime to represent numbers using the current culture, the typical usage of an attribute is ``` [Range(typeof(decimal), ""0.1"", ""0.9"")] public decimal Value { get; set; } ``` where the values **must** be constants, and can't change depending on the culture. Culprit line: https://github.com/dotnet/corefx/blob/master/src/System.ComponentModel.Annotations/src/System/ComponentModel/DataAnnotations/RangeAttribute.cs#L203 The fix can't be to simply change `CurrentCulture` to `InvariantCulture` here, since this will alter the runtime validation behavior: `InvariantCulture` should be used to convert the `min` and `max` parameters (maybe falling back to `CurrentCulture` for back-compat, if the constructor was used directly), but `CurrentCulture` should be kept to validate the user-entered value. If accepted, I can add some unit tests and a fix for this issue.

" 2703 area-System.Threading Add a way to wait for a task without throwing `Task.Wait` throws an exception if the task is faulted or cancelled. Sometimes it is necessary to wait for completion but not be interrupted by an exception. Catching and swallowing the exception is a really bad workaround. Using exceptions for control flow is not a good thing. Also, exceptions are extremely slow. 1. The `Wait` method should have an overload that allows the caller to specify that he does not want an exception. 2. There should be a method `Task WhenCompleted(this Task task)` that returns a new task that becomes completed when the base task becomes completed. Cancellation and exceptions should not be propagated. That way we can write `await myTask.WhenCompleted()` to avoid exceptions. 3. In the same spirit as (2) there probably should be `WhenCompletedSuccessfully`, `WhenCancelled` and `WhenFaulted`. These tasks complete when the underlying task transitions to the respective state. They do not ever complete if the underlying task transitions to a different final state. They should _not_ become cancelled in that case because the idea of these methods is that you can avoid exceptions for control flow in a convenient manner. 2705 area-System.Net Fixing multi response header issue along with putting checks in http message parser. …message parser ``` modified: System/Net/Http/Unix/CurlCallbacks.cs ``` 2711 area-System.Reflection Merge master into dev/metadata @tmat @stephentoub @nguerrera 2715 area-System.Security System.Security.Cryptography.Hashing.Algorithms contract reference is forwarding Hi, It seems that in System.Security.Cryptography.Hashing.Algorithms v4.0.0-beta-23127 all types are being forwarded, even though they are implemented in corefx.

In System.Collections.HashHelpers and System.Collections.NonGeneric\src\System\Collections\Hashtable and System.Private.DataContractSerialization\src\System\Runtime\Serialization\ObjectToIdCache.cs there are copies of the same function: private static bool IsPrime(int candidate) It is used by: private static int GetPrime(int min) Which is called by: Initialize, ExpandPrime, and TrimExcess They all use a table in GetPrime: E.g. int[] primes = {3, 7, 17, 37, 89, 197, 431, 919, 1931,...7199369}. Notice that each successive prime is larger than twice the preceding one. This appears to be because hashtables are doubled in size when they need to be expanded. But they are only allowed to expand up to 2G. The GetPrime function calls IsPrime to find a prime when the search goes above the limit of the primes table. The ExpandPrime function is the most interesting as it more than doubles the size each time: public static int ExpandPrime(int oldSize) { int newSize = 2 \* oldSize; .... return GetPrime(newSize); Therefore it appears that we don't need the IsPrime function at all. Instead we simply need to expand the primes table up to 2146435069 (largest prime below 2G). {..., 7199369, 21598111, 64794337, 194383039, 583149179, 1749447569, 953375459, 2146435069}; Recommendation: 1) Use a common GetPrime(int min) function instead of having three copies 2) Expand the primes table as described above. 3) Remove the IsPrime function, modify GetPrime to only use the table. 2729 area-System.Numerics Fix very sporadically failing Complex test "I'd previously ""fixed"" this same test by incorporating infinity support, but I needed to do the comparisons based on IsNegative/PositiveInfinity rather than by comparing the values directly. cc: @mellinoe " 2730 area-System.IO Reworked the tests for System.IO.Pipes I made a number of changes to our current Pipes tests and added several hundred new tests for edge cases that were previously ignored, particularly with Named Pipes defined with an InOut PipeDirection - Refactored the great Throws tests currently in place to allow testing pipes with all in/out direction combinations for both Named pipes as well as Anonymous pipes - Replaced all relevant hardcoded pipe names with unique values - Reorganized the tests to use more inheritance and share more code for easy extensibility - All test classes are now in the same namespace: System.IO.Pipes.Tests - Expanded tests for InOut NamedPipes and made all existing In/Out tests also test all valid InOut combinations. - Split the Named and Anonymous tests into two separate folders: NamedPipeTest and AnonymousPipeTest - Increased code coverage across all test classes 2732 area-System.Numerics what set's Vector.IsHardwareAccelerated to true in System.Numerics.Vectors?

Similar to #2743, the fix would be to not use the helper function, but to get into the nitty-gritty with PKCS12 primitives. 2746 area-System.Security CryptographicException on Unix when exporting an empty collection as a PFX This has the same underlying function as a cause as #2743, `PKCS12_create`. Since it never added anything to an authsafe it never created the authsafe stack, and then reports a data validation error because it didn't expect a `NULL` to make it through. When/if we switch to creating PFX files without the helper function's limitations this should go away (but it's a separate problem, and could accidentally not be fixed, so a separate issue). 2751 area-System.Diagnostics Trace.IndentLevel does not behave consistently when used from multiple threads "According to [the documentation](https://msdn.microsoft.com/en-us/library/system.diagnostics.trace.indentlevel), `Trace.IndentLevel` should be stored on a per-thread basis. And [it is](https://github.com/dotnet/corefx/blob/41e203011152581a6c65bb81ac44ec037140c1bb/src/System.Diagnostics.TraceSource/src/System/Diagnostics/TraceInternal.cs#L16), but [a cached version is also kept in each `TraceListener`](https://github.com/dotnet/corefx/blob/41e203011152581a6c65bb81ac44ec037140c1bb/src/System.Diagnostics.TraceSource/src/System/Diagnostics/TraceListener.cs#L18). And since listeners are shared among all threads and the listener-cached version of `IndentLevel` is updated only when `Trace.IndentLevel` changes on some thread, this means that the actual indent level that is printed is the indent level of the last thread that changed it, it doesn't matter what the indent level of the current thread is. Sample application to replicate the issue: ``` c# using System; using System.Diagnostics; using System.Threading; using System.Threading.Tasks; namespace TraceIndentLevel { static class Program { static void Main() { Trace.Listeners.Add(new ConsoleTraceListener()); Task.WaitAll(Task.Run((Action) T1), Task.Run((Action) T2)); } static readonly Barrier barrier = new Barrier(2); static void T1() { Trace.Indent(); Trace.Indent(); Trace.TraceInformation(""Thread 1, IndentLevel should be {0}."", Trace.IndentLevel); barrier.SignalAndWait(); barrier.SignalAndWait(); Trace.TraceInformation(""Thread 1, IndentLevel should be {0}."", Trace.IndentLevel); // this should be a noop, but isn't Trace.IndentLevel = Trace.IndentLevel; Trace.TraceInformation(""Thread 1, IndentLevel should be {0}."", Trace.IndentLevel); } static void T2() { barrier.SignalAndWait(); Trace.TraceInformation(""Thread 2, IndentLevel should be {0}."", Trace.IndentLevel); Trace.Indent(); Trace.TraceInformation(""Thread 2, IndentLevel should be {0}."", Trace.IndentLevel); barrier.SignalAndWait(); } } } ``` On my computer (using desktop .Net, but I believe core will behave the same), this prints: ``` TraceIndentLevel.exe Information: 0 : Thread 1, IndentLevel should be 2.

TraceIndentLevel.exe Information: 0 : Thread 1, IndentLevel should be 2.

TraceIndentLevel.exe Information: 0 : Thread 2, IndentLevel should be 0. TraceIndentLevel.exe Information: 0 : Thread 2, IndentLevel should be 1.

For example, ``` C# using Microsoft.CodeAnalysis.Scripting.CSharp; public class Globals { public int x; public int y; } class Program { public static void Main() { var globals = new Globals() { x = 1, y = 2 }; var options = ScriptOptions.Default.WithReferences(typeof(MyMath).Assembly); var script = CSharpScript.Create(""MyMath.CalculateStuff(x, y)"", options); Console.WriteLine(script.RunAsync(globals).Result); } } ``` In the example above `MyMath` is a type defined in an assembly referenced by and deployed with the program. The script is compiled with the following metadata references: mscorlib, the assembly containing the `Globals` type and an assembly containing `MyMath` class. All these assemblies are implementation (runtime) assemblies, not contracts. Since we are compiling scripts at runtime contracts are not relevant. The application might also run on a machine that doesn’t have any SDK. It is natural for scripting to be able to execute virtually any (public) runtime method available in any loaded assembly. Just like Reflection invocation. On Desktop CLR we use Assembly.Location to find the metadata image for given assembly. On Core CLR this property is not available and there is no other way to get the metadata of a given runtime assembly. # Proposed API We propose that the metadata of a runtime assembly are exposed thru new APIs in a form that is efficiently readable using MetadataReader of System.Reflection.Metadata library. Since metadata might not be available for all assemblies (such as AssemblyBuilder, .NET Native images, etc.) the API is allowed to return false for such assemblies. Roslyn scripting API would then report an error that the script can’t reference specified assembly. ``` C# namespace System.Reflection.Metadata { public static class AssemblyExtensions { public unsafe static bool TryGetRawMetadata(this Assembly assembly, out byte* blob, out int length); } } ``` **Lifetime considerations** The pointer would stay valid as long as the `AssemblyLoadContext` with which is the assembly associated is alive. It is the responsibility of the caller to keep the Assembly object alive while accessing the metadata blob. # Considered alternatives It was suggested that Roslyn uses Reflection API to read the metadata. There are multiple issues with such approach. 1) Expected bad performance (both working set and time) Reflection is built on top of IMetadataImport. It was measured that using IMetadataImport to reader metadata from managed code is an order of magnitude slower than using S.R.M. MetadataReader, which was not an acceptable perf hit for the compilers. Reflection API implementation adds additional memory and time overhead. Although the number of referenced assemblies is relatively low in most scripting scenarios reducing the compile time of scripts to minimum is crucial for good user experience. 2) Using Reflection APIs to read namespaces and types To get a list of namespaces in given assembly one needs to load all types in the assembly. Loading a type may trigger additional assembly loads as well (those of the base types, interfaces). If a type can’t be loaded (perhaps a dependency is missing) we get a loader exception. We can extract the loaded types from the exception, but what if the app makes the dependency available just before it is about to actually start using the type? Our model is immutable, we can’t add a type/namespace into an existing assembly symbol. 3) Missing APIs Brief analysis identified missing APIs that the compiler depends on and that are not present in DNX contracts: for example, type forwarders, GetOptionalCustomModifiers, GetRequiredCustomModifiers, class layout. Besides missing APIs Reflection performs post-processing on the data it receives from IMetadataImport that might render the values useless to the compiler. 4) Roslyn-Reflection interop We have prototyped an abstraction of Reflection symbol model to incorporate interop with Reflection runtime types. The abstraction introduces quite a lot of complexity and indirections in already complex code, which significantly increases maintenance cost of that particular area of the compiler. Testing cost would also need to be considered. We would need to effectively run most of our compiler tests twice. # Updates 1) Decided to move this to `System.Reflection.Metadata` namespace.

This should give us real collation support instead of our ASCII only collation. 2770 area-System.Globalization System.Globalization: Locale Data Implement the PAL's from [CultureData](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/CultureData.Unix.cs) and [CultureInfo](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/CultureInfo.Unix.cs). 2772 area-System.Globalization System.Globalization: Casing Implement the [TextInfo](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/TextInfo.Unix.cs) PAL. 2773 area-System.Globalization System.Globalization: Calendars Fill out the PAL implementation of [CalendarData.cs](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/CalendarData.Unix.cs), [HijriCalendar.cs](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/HijriCalendar.Unix.cs) and [JapaneseCalendar.cs](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/corefx/System/Globalization/JapaneseCalendar.Unix.cs) 2774 area-System.Globalization System.Globalization: Encodings We have stubbed out [EncodingTable.cs](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Globalization/EncodingTable.Unix.cs) and [EncodingDataItem.cs](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Globalization/EncodingDataItem.Unix.cs) for cross platform, but it is not clear the implementation is correct or if we need to do more. I think the big issue here will be understanding if System.Text.Encoding.Codepages and the EncodingProvider model here reduces the scope of work that we need to. 2777 area-System.Globalization System.Globalization.Extensions: Normalization We need to implement [StringNormalizationExtensions.cs](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/StringNormalizationExtensions.Unix.cs) for Linux. The major difference between ICU and Win32 is that Win32 throws an exception when the input is not a valid UTF-16 encoded string (e.g. mismatched surrogates) whereas ICU does not. 2778 area-System.Security Add ECDsa to System.Security.Cryptography suite - `ECDsa` in System.Security.Cryptography.Algorithms - `ECDsaCng : ECDsa` in System.Security.Cryptography.Cng - `ECDsaOpenSsl : ECDsa` in System.Security.Cryptography.OpenSsl - Some tests (Common\test\Cryptography\AlgorithmImplementations\ECDsa) - Other artifacts required to pull this off. - Like the contract assembly changes 2779 area-System.Globalization System.Globalization.Extensions: IDNA We need to support [IdnMapping.cs](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Globalization/IdnMapping.Unix.cs) for IDNA2008 on Unix. This is straightforward on-top of ICU, but many of our existing ICU tests assume either ICU2003 or ICU2008 as implemented by Win32. There are some differences between 2008 and 2003 in ICU for compatibility, especially around how windows works when UseStd3Rules is false. In speaking with NLS, they think it may make sense for us to just follow the 2008 standard. 2782 area-System.Diagnostics Add a way to create a suspended Process It seems that there is no way to create a suspended `Process` and resume it later. Ability to create a suspended process is useful when you want to run the process and its children in a job object. If the process isn't created as suspended it may create child processes before it is assigned to the job object which means that these child processes won't be assigned to the job object. 2784 area-System.Net Enabled max redirection in HTTP xplat ``` modified: ../../Common/src/Interop/Unix/libcurl/Interop.libcurl_types.cs modified: System/Net/Http/Unix/CurlHandler.cs modified: System/Net/Http/Unix/HttpClientHandler.Unix.cs ``` Enabled max redirection support in HTTP xplat 2785 area-System.Net Server Credential Support for CurlHandler This check-in integrates curlHandler with the credential support of libcurl. 2787 area-System.Net Use common class to set property default in winHttp & xplatHttp > stephentoub :: There are a bunch of these default values that are being copied from the WinHttp handler implementation. It's great that we're using the same defaults, but it's error prone that we're doing so via copy-and-paste. I see a whole bunch of constants/defaults in WinHttp at https://github.com/dotnet/corefx/blob/master/src/System.Net.Http.WinHttpHandler/src/System/Net/Http/WinHttpHandler.cs#L93-L146 .could we somehow factor out these constants/default values into a shared source file that's included in both the Windows and Unix implementation, such that this then becomes: > > ``` C# > private int _maxAutomaticRedirections = HttpHandlerDefaults.MaxAutomaticRedirections; > ``` > > instead of: > > ``` C# > private int _maxAutomaticRedirections = 50; > ``` > > davidsh :: Yes, one could create a shared source file in src\Common\src\System\Net\Http... that defined an internal static class (HttpHandlerDefaults) with those constants defined as public fields. Then that file would be used in the multiple .CSPROJ files to bring in the values. 2791 area-System.Net Unsupported address family assert in System.Net.SocketAddressPal.SetPort on Linux in CI

This makes tools like VSCode impossible to use due to the large quantity of files they need to index. A workaround to use VSCode is to load only the \src folder but that is breaking the Git extension which requires the root of the repo to be loaded. Another reason is using a different partition for binaries that can be quickly formatted when the binaries and packages are not wanted anymore or placing it on a faster disk. 2804 area-System.Globalization System.Globalization: Abbreviated genitive month names won't work on custom DateTimeFormat strings "As found out by @jskeet , abbreviated genitive month names don't seem to work when using the ""MMM"" token on custom datetime format strings The test, written by @jskeet (I'm just copying here from https://github.com/nodatime/nodatime/issues/377): ``` using System; using System.Globalization; using System.Linq; class Test { static void Main() { var culture = (CultureInfo) CultureInfo.InvariantCulture.Clone(); culture.DateTimeFormat.AbbreviatedMonthGenitiveNames = culture.DateTimeFormat.AbbreviatedMonthNames .Select(x => ""Gen"" + x) .ToArray(); culture.DateTimeFormat.MonthGenitiveNames = culture.DateTimeFormat.MonthNames .Select(x => ""Gen"" + x) .ToArray(); Console.WriteLine(new DateTime(1976, 6, 19).ToString(""d MMMM yy"", culture)); Console.WriteLine(new DateTime(1976, 6, 19).ToString(""MMMM yy"", culture)); Console.WriteLine(new DateTime(1976, 6, 19).ToString(""d MMM yy"", culture)); Console.WriteLine(new DateTime(1976, 6, 19).ToString(""MMM yy"", culture)); } } ``` Should output: ``` 19 GenJune 76 June 76 19 GenJun 76 Jun 76 ``` But outputs: ``` 19 GenJune 76 June 76 19 Jun 76 Jun 76 ``` Disregarding the abbreviated genitives (and resorting to regular ones when abbreviated). I haven't found the DateTimeFormat files on GitHub yet (just the tests, which don't cover this), so I can't issue a request or test it, but on the reference source: http://referencesource.microsoft.com/#mscorlib/system/globalization/datetimeformat.cs,578 We got this: ``` if ((dtfi.FormatFlags & DateTimeFormatFlags.UseGenitiveMonth) != 0 && tokenLen >= 4) { result.Append( dtfi.internalGetMonthName( month, IsUseGenitiveForm(format, i, tokenLen, 'd')? MonthNameStyles.Genitive : MonthNameStyles.Regular, false)); ``` Which doesn't take MMM into account (because of the `tokenLen >= 4` conditional). If I'm not mistaken, it should look like this: ``` if ((dtfi.FormatFlags & DateTimeFormatFlags.UseGenitiveMonth) != 0 && tokenLen >= 3 /* Work for MMM and MMMM */ ) { result.Append( dtfi.internalGetMonthName( month, IsUseGenitiveForm(format, i, tokenLen, 'd')?

It seems that both have the draw back of not permitting an upgrade to latest stable version, or moving past any changes in the major.minor.build version. In most places the semantics we want is either 4.0._: latest of a given API version or 4.*: latest API of a major release. In conjunction with this we need to experiment with how to use policy to impact the behavior of restore. In some cases we want ""minimum that satisfies the constraint"" in others we want ""latest that satisfies the constraint"". /cc @weshaggard " 2817 area-Infrastructure Investigate: Partial facades should build against stable packages Today partial facades are building against live dependencies via P2P reference for other contracts. This means that they always need to reference the latest version of their contract dependencies. We should see if we can break this to allow the partial facades to version more independently. 2833 area-System.Net Credential Support in Unix HTTP Handler This checkin integrates CurlHandler to the credential support available in libcurl 2836 area-System.IO Add method for calculating relative paths It would be great if this super common functionality could be added to the path class.

Related https://github.com/dotnet/corefx/issues/1745 2837 area-System.Threading SemaphoreSlim Dispose thread safety The documentation of SemaphoreSlim says 'Dispose should only be used when all other operations have completed'. In practice, for me, I don't bother to Dispose the SemaphoreSlim because I would need to add synchronization to Dispose of this synchronization class. See also, this [question on stackoverflow](http://stackoverflow.com/questions/32035891/dispose-a-semaphoreslim-while-waitasync). Can SemaphoreSlim be extended so pending operations on other threads throw ObjectDisposedException? Related to this, I noticed some of the other synchronization classes in System.Threading do not properly document the thread safety behavior of their Dispose method. Furthermore, the reference source of ReaderWriterLockSlim shows a check in the Dispose method which throws a SynchronizationLockException when the Dispose conditions are not met. SemaphoreSlim and other classes could do the same. 2840 area-System.Net Enabling POST method options 2844 area-System.Linq Implement IList in Linq responses when possible There is code throughout .NET that accepts arguments of `IEnumerable` and has an optimised path for `IList` and/or `ICollection`. Some methods of `System.Linq.Enumerable` would be examples, but also elsewhere such as some collections' constructors. The effect upon `.ToList()`, `.ToArray()` and any operation in `Enumerable` that requires buffering are perhaps particularly of note here. Some methods of `Enumerable` have results which are conceptually lists. E.g. `Repeat` returns a sequence of a specified size where all items are the same, which can be modelled as a read-only list. Some methods of `Enumerable` have results which can be conceptually lists in certain conditions. E.g. If `Select` is called on a source that is itself a list, then the result would be a read-only list of the same size as the source list, and a different type. Returning such list types when possible would increase the times that the existing fast-paths for list types are made use of. At the same time, some such changes would add further such cases, potentially allowing chains of operations that cannot currently hit such fast-paths to do so. 2849 area-System.Security Add support for importing PKCS7 files on Unix 2851 area-Meta Port legacy LINQ tests to Git/XUnit "Current active test coverage for LINQ is not very great. While sources were ported and published, many old legacy tests has been left behind. It is not an easy task to port them to Git/XUnit, but mostly just because of the test volume and because they are not XUnit tests. It would be nice to port them over. Also it would be preferable to port these tests over writing new ones, because the old tests are by definition ""correct"". I.E. any deviation from the behavior guarded by those tests could be a compatibility issue. I have collected and pushed a lot of old legacy tests for LINQ to https://github.com/VSadov/corefx/tree/UnportedLegacyTests branch. Actual tests are at: https://github.com/VSadov/corefx/tree/UnportedLegacyTests/src/System.Linq/LegacyTestsToPort/LINQ " 2857 area-System.Net HttpClient Timeout Confusion The HttpClient from the System.Net.Http package has Timeout property that defaults to a 100 seconds which as I read through the code just means how long till the task is cancelled. The underlying windows handler WinHttpHandler has the timeout properties ConnectionTimeout, SendTimeout, ReceiveHeadersTimeout and ReceiveDataTimeout which default to 30 seconds except for ConnectionTimeout which defaults to 60 seconds. If you have an operations that takes say 40 seconds before it return back any data it will always timeout after 30 seconds. Only way to get around this is to code against the platform specific WinHttpHandler and set the timeout properties. Am I missing something about how to set timeout in a platform agnositic approach? Here is the code I wrote that directly uses the WinHttpHandler but I want to code just against the HttpClientHandler. ``` private HttpClient CreateHttpClient() { var httpMessageHandler = new System.Net.Http.WinHttpHandler(); httpMessageHandler.SendTimeout = TimeSpan.FromSeconds(200); httpMessageHandler.ReceiveDataTimeout = TimeSpan.FromSeconds(200); httpMessageHandler.ReceiveHeadersTimeout = TimeSpan.FromSeconds(200); var httpClient = new HttpClient(httpMessageHandler); httpClient.Timeout = TimeSpan.FromSeconds(200); return httpClient; } ``` 2862 area-System.Collections Add HashSet ctors with capacity Replaces PR #2122.

The documentation states the following: > The wait thread uses the Win32 WaitForMultipleObjects function to monitor registered wait operations. Therefore, if you must use the same native operating system handle in multiple calls to RegisterWaitForSingleObject, you must duplicate the handle using the Win32 DuplicateHandle function. It seems quite bad when the documentation is encouraging you to write non-portable code, and P/Invoking to DuplicateHandle requires full trust. Would it be a big problem to detect that the same handle is there twice with two different registrations and correctly wait for it and queue both action on the thread pool when the waithandle becomes ready? 2869 area-Meta Merge future branch back into master This issue is just for tracking the changes we have merged into future so when we merge it back to master we know which API changes we need to modify contracts and ensure are supported on our other platforms like the desktop framework.

This commit adds support to use either ZLib or the Managed implementation for decompression (inflation). - Resolves #2024; Added ZLib support in InflaterZLib.cs - Inflater.cs the old managed implementation is renamed to InflaterManaged.cs - Extracted interface of necessary Inflater methods into the IInflater interface from which InflaterManaged and InflaterZLib inherit. - Roughly a 3X speedup for decompression when using the ZLib library instead of the Managed implementation! 2907 area-System.Net Merge changes from TFS 2910 area-System.Security new X509Certificate2(byte[]) should return the signing cert for PKCS#7 on Unix The Windows code supports reading a PKCS#7 signed or PKCS#7 signed-and-enveloped structure; but in single certificate mode it doesn't return certs[0], it returns the certificate which signed the structure. My test files (produced by Windows (certmgr.msc and X509Certificate2Collection::Export)) aren't signed, so Windows emits an exception (`new CryptographicException(ErrorCode.CRYPT_E_SIGNER_NOT_FOUND)`). Without a sample to see what's going on here, it's hard to make compatible behavior.

Since we are interested in only reading on it, scoping down to POLLIN prevents this from happening. Else we attempt a read on it which fails - CheckForCompletedTransfers was being unnecessarily called from the socket callback. We are only interested in MSG_DONE after the socket callback indicates removal. This will anyway wake up PollFunction which calls CheckForCompletedTransfers.

It succeeded. SChannel got ALPN support in the Windows 8 timeframe. .NET's SslStream class does not have ALPN support, preventing low-level socket clients (like Fiddler) from sending ALPN tokens to servers during TLS handshaking, in turn blocking support of the HTTP/2 protocol. The code change to SslStream is probably a dozen lines at worst. The current workaround for those blocked by this shortcoming is to take on a **massive** security risk and ship either BouncyCastle or OpenSSL (or re-wrap SChannel, I guess). 2930 area-System.Security Change Windows GetRSAPrivateKey to prefer CNG When GetRSAPrivateKey was added into the repository the CNG types weren't yet online.

The issue on [Microsoft Connect](https://connect.microsoft.com/VisualStudio/feedback/details/1431526/nat-traversal-udp-hole-punching-not-possible-in-windows-store-apps-even-with-internet-client-server-capability).

The only methods to send and receive are [`SendAsync`](https://msdn.microsoft.com/en-us/library/system.net.sockets.socket.sendasync%28v=vs.110%29.aspx) and [`RecieveAsync`](https://msdn.microsoft.com/en-us/library/system.net.sockets.socket.receiveasync%28v=vs.110%29.aspx). Despite the names they are not `async` methods but an old school variant to which one supplies the `SocketAsyncEvenArgs` parameter _shudder_. We need to bring .NET Core's `Socket` up-to-date and provide `async` variants. Also consider synchronous methods since `Socket`s are often used in in background processes with dedicated threads where that is wanted (applications tend to use higher application level type such as `HttpClient`). 2938 area-System.Runtime GC tests GetTotalMemoryTest_ForceCollection, GetGenerationTest test failed in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx_windows_release/1057/console ``` GCTests.GetTotalMemoryTest_ForceCollection [FAIL] Assert.True() Failure Expected: True Actual: False Stack Trace: d:\j\workspace\dotnet_corefx_windows_release\src\System.Runtime\tests\System\GC.cs(295,0): at GCTests.GetTotalMemoryTest_ForceCollection() ``` We should probably just delete these tests. 2942 area-System.Threading Request to Add Timer.Dispose(WaitHandle) API in CoreCLR. We are working on porting our .Net 4.5 application to the .Net Core CLR platform. We have multiple services implemented in our application which need to do some work every so often. Currently this is implemented using System.Threading.Timer with a callback method that is responsible for scheduling the next callback. During cleanup, we want to wait until we are sure that the callback is no longer running and will not run in future. Currently we do this using Threading.Timer.Dispose(WaitHandle) with additional synchronization mechanism to avoid the ObjectDisposedException. Since CoreCLR doesn't have Timer.Dispose(WaitHandle) implemented, every application/service now has to implement Timer.Dispose(WaitHandle) logic using some synchronization mechanism in their code. This adds complexity at each place where this API is used currently. We would like to carry forward the same behavior and so would request to add this API [Timer.Dispose(WaitHandle)] back in CoreCLR. Thanks, Mehul. 2944 area-System.Net Fix an assert in CurlHandler multi handle release path - If a timeout happens, the socket fd is not removed from _fdSet.

The idea is to avoid 4KB allocation for buffer whenever we need to work with large number of files. Consider the following code: ``` foreach (var file in System.IO.Directory.GetFiles(dirToCheck, ""*.dat"")) { using (var fs = new FileStream(file, FileMode.Open)) { // do something to read from the stream } } ``` The problem is that each instance of FileStream will allocate an independent buffer. If we are reading 10,000 files, that will result in 40MB(!) being allocated, even if we are very careful about allocations in general. See also: https://github.com/dotnet/corefx/pull/2929 The major problem is that FileStream will allocate its own buffer(s) and provide no way to really manage that. Creating large number of FileStream, or doing a big writes using WriteAsync will allocate a lot of temporary buffers, and generate a _lot_ of GC pressure. As I see it, there are a few options here: - Add a constructor that will take an external buffer to use. This will be the sole buffer that will be used, and if a bigger buffer is required, it will throw, instead of allocating a new buffer. - Add a pool of buffers that will be used. Something like the following code: [ThreadStatic] private static Stack[] _buffersBySize; private static GetBuffer(int requestedSize) { if(_buffersBySize == null) _buffersBySize = new Stack[32]; ``` var actualSize = PowerOfTwo(requestedSize); var pos = MostSignificantBit(actualSize); if(_buffersBySize[pos] == null) _buffersBySize[pos] = new Stack(); if(_buffersBySize[pos].Count == 0) return new byte[actualSize]; return _buffersBySize[pos].Pop(); ``` } private static void ReturnBuffer(byte[] buffer) { var actualSize = PowerOfTwo(buffer.Length); if(actualSize != buffer.Length) return; // can't put a buffer of strange size here (prbably an error) ``` if(_buffersBySize == null) _buffersBySize = new Stack[32]; var pos = MostSignificantBit(actualSize); if(_buffersBySize[pos] == null) _buffersBySize[pos] = new Stack(); _buffersBySize[pos].Push(buffer); ``` } The idea here is that each thread has its own set of buffers, and we'll take the buffers from there. The Dispose method will return them to the thread buffer. Note that there is no requirement to use the same thread for creation / disposal. (Although to be fair, we'll probably need to handle a case where a disposal thread is used and all streams are disposed on it). The benefit here is that this isn't going to impact the external API, while adding the external buffer will result in external API being visible. " 2963 area-System.Net Handle leak with WinHttpHandler "The following test demonstrates an unbounded leak of both memory and handles: ``` C# [Fact] public void TestLeak() { while (true) { HttpClient client = new HttpClient(); client.GetStringAsync(""http://www.httpbin.org"").Wait(); // client.Dispose(); } } ``` At least one problem appears to be that without explicitly Dispose'ing of the HttpClient instance, the underlying session SafeHandle is never cleaned up. When the session handle is created, it's DangerousAddRef'd (https://github.com/dotnet/corefx/blob/master/src/System.Net.Http.WinHttpHandler/src/System/Net/Http/WinHttpHandler.cs#L992), and then DangerousRelease is only called if explicitly Dispose'ing (https://github.com/dotnet/corefx/blob/master/src/System.Net.Http.WinHttpHandler/src/System/Net/Http/WinHttpHandler.cs#L555).

I believe that adding empty dependencies group for .NET 4.5 as can be seen in [AutoMapper nuget package](https://www.nuget.org/packages/AutoMapper/) (for example) would fix the issue and those dependencies would not be downloaded.

This class exposes two sets of APIs: some methods, and their corresponding properties. For example, DateTimeFormat has a GetMonthName(int) method, that returns the name of the specified month. And then it has a corresponding property MonthNames, that is a string array of all the month names. This is true for Month Names, Abbreviated Month Names, Day Names, and Abbreviated Day Names. And in the full framework, this holds true for Shortest Day Names: string GetShortestDayName(DayOfWeek) & string[] ShortestDayNames. However, in the .NET Core contracts, the string[] property ShortestDayNames is public, but the method GetShortestDayName(DayOfWeek) is not exposed. I see this [is true for Silverlight](https://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo%28v=vs.95%29.aspx) as well.

Just a few minor tweaks. @kapilash: The second commit is your commit with new tests from #2916, which this PR replaces. @kapilash, @vijaykota: The third commit is the majority of the changes for this PR... CurlHandler is now split into three types: - CurlHandler, which represents the shell of the handler, contains some helper functions, and contains a ""MultiAgent"". It submits ""EasyRequest""s to the ""MultiAgent"". - CurlHandler.EasyRequest, which represents all of the state associated with a SendAsync request on the HttpClient. - CurlHandler.MultiAgent, which represents the owner of a libcurl multi handle and all of the processing associated with it. The MultiAgent is responsible for actually processing EasyRequests, which CurlHandler queues to it. MultiAgent is designed to not require any cleanup. When the first EasyRequest arrives, it spins up a worker that creates a multi handle to process the request. Any additional requests to arrive while that worker is active will be processed by that worker and multi handle. When no work remains, the multi handle and the worker goes away. If/when another request arrives, a new multi handle / worker are spun up. Etc. Almost all of the locking previously there was removed, as the worker thread is now solely responsible for doing all work on the multi handle; any requests for processing come in through the requests queue processed by that thread. This design avoids threading issues we faced with regards to accessing state managed by the multi handle without holding the lock (e.g. polling file descriptors) and avoids having multiple threads blocked waiting on the lock to do processing associated with the multi handle. It also makes resource cleanup much easier and more deterministic: all state associated with the easy handle is cleaned up when that thread is done processing the easy handle, and all state associated with the multi handle is cleaned up when the worker thread shuts down. The change also ensures that we always complete the response message, and that any exceptions that occur are propagated as needed to Read on the response stream (fixes #3015). Further, the design will make it trivial in the future to change the relationship between a CurlHandler and a MultiAgent: - If we want one MultiAgent shared across all CurlHandlers, we just change the _agent field to be static instead of instance. - If we want a pool of MultiAgents, we can simply create a collection of them and round-robin between them from one or more CurlHandlers. - Etc. All of the configuration code remains, e.g. what options are set on the easy and multi handles, but the code has been refactored. I also include CURLOPT_NOSIGNAL to avoid multithreading problems per the docs. Along the way, I cleaned up some stale interop that's gotten left behind through various iterations, and I fixed a few small issues related to behavioral differences from Windows, e.g. CookieContainer never returning null, UseCookies defaulting to true, etc. (Fixes #3016) " 3051 area-Meta Create a C++ coding standard for the PAL layer Create a C++ code style document describing coding standards and naming standards to use the PAL layer.

For example: ``` c# internal class CustomAssemblyLoadContext : AssemblyLoadContext { [DllImport(""kernel32"")] private static extern IntPtr LoadLibrary(string path); [DllImport(""libdl"")] private static extern IntPtr dlopen(string path, int flags); protected override IntPtr LoadUnmanagedDll(String unmanagedDllName) { if (!ShouldLoadFromCurrentDirectory(unmanagedDllName)) { return IntPtr.Zero; // use the default loader } var libraryPath = Path.Combine(Environment.CurrentDirectory, unmanagedDllName); IntPtr libraryHandle = EnvironmentHelper.IsWindows ? LoadLibrary(libraryPath) : dlopen(libraryPath, 0); if (libraryHandle == IntPtr.Zero) { // ... (more error handling) throw new DllNotFoundException(unmanagedDllName); } return libraryHandle; } } ``` The proposal is to add an API to `AssemblyLoadContext` to provide a platform-independent way of loading an unmanaged library: ``` c# internal class CustomAssemblyLoadContext : AssemblyLoadContext { protected override IntPtr LoadUnmanagedDll(String unmanagedDllName) { if (!ShouldLoadFromCurrentDirectory(unmanagedDllName)) { return IntPtr.Zero; // use the default loader } var libraryPath = Path.Combine(Environment.CurrentDirectory, unmanagedDllName); return LoadUnmanagedDllFromPath(libraryPath); } } ``` ## Proposed API ``` c# namespace System.Runtime.Loader { public abstract class AssemblyLoadContext { // Relevant existing members protected abstract Assembly Load(AssemblyName assemblyName); protected Assembly LoadFromAssemblyPath(string assemblyPath); protected virtual IntPtr LoadUnmanagedDll(String unmanagedDllName); // Proposed members protected IntPtr LoadUnmanagedDllFromPath(String unmanagedDllPath); } } ``` ## Details ### Usage and behavior - `unmanagedDllPath` must be an absolute path to the library to load - No changes are made to the specified search path or library name in `unmanagedDllPath` before attempting the load. For example, no prepending ""lib"" and no appending "".so"".

Actually, the (unsigned) Byte versions of these tests will also break once they run on AVX512, since 64-byte vectors will easily overflow an unsigned byte with this calculation, as well.

As such, any consumers reading data using ReadAsync will actually end up blocking a thread pool thread doing a synchronous Read. This commit fixes that by implementing ReadAsync to be truly asynchronous with no additional threads blocked. If data is already available, a task is returned immediately. Otherwise, the reader asynchronously waits for the writer to publish data and then consumes that data. The overall design of the response stream remains the same as it was. However, there are some notable changes: - A SemaphoreSlim is now used instead of a ManualResetEventSlim for the _writerPublishedDataEvent. This was done because SemaphoreSlim supports both synchronous and asynchronous waiting. - The _readerRequestingDataEvent was removed, as it was no longer necessary. - We no longer allocate an UnmanagedMemoryStream per write operation, instead simply storing the IntPtr buffer and long length on the response stream. - Additional reorganization was done, primarily to share logic between Read and ReadAsync. - A bunch of comments and debug asserts were added. A second commit enables the asynchronous wait to be canceled by either the internal shutdown CancellationToken or by the CancellationToken provided by the caller to ReadAsync.

" 3089 area-System.Net CurlHandler blocking write callback can lead to deadlock With the current implementation of CurlHandler in HttpClient on Unix, when downloaded data is available, libcurl invokes a callback to provide that data to the application. Until a reader is available to consume all of that data, the callback blocks. I'd previously noted this as a performance problem to be fixed, but it's actually a much worse problem in that it can easily lead to deadlock. Here's a new test to demonstrate: ``` C# [Fact] public async Task GetAsync_ResponseHeadersRead_ReadFromEachIterativelyDoesntDeadlock() { using (var client = new HttpClient()) { const int NumGets = 5; Task[] responseTasks = Enumerable.Range(0, NumGets) .Select(_ => client.GetAsync(HttpTestServers.RemoteGetServer, HttpCompletionOption.ResponseHeadersRead)) .ToArray(); for (int i = responseTasks.Length - 1; i >= 0; i--) { using (HttpResponseMessage response = await responseTasks[i]) { await AssertSuccessfulGetResponse(response, HttpTestServers.RemoteGetServer, _output); } } } } ``` Here we kick off N downloads and then iteratively process each to completion before moving on to process the next. This means that we only try to read from a single download at a time, and if this doesn't happen to be the same download that has data available next, our reader will block waiting for data, which will never come because the libcurl callback is blocked waiting for a reader for a different download. We should fix this by employing libcurl's ability to pause connections. When the write callback is invoked, if there isn't currently a read pending on that download, the write callback should return to libcurl to inform it that the connection needs to be paused. When the reader later comes along, it needs to unpause that connection. Obviously there will be some synchronization required here, but it shouldn't be too bad. cc: @vijaykota, @kapilash 3091 area-System.Net Enabling Testcases for POST/PUT methods 3093 area-System.Linq Add static method to create an IEnumerable with one element I find that I need the following static method quite often: ``` csharp public static class MoreEnumerableMethods { // ... public static IEnumerable Singleton(TResult element) { return Repeat(element, 1); } } ``` This seems like a really good fit for `Enumerable` itself, where it would live alongside `Repeat`, `Empty`, and `Range`.

In investigating the leaks, I discovered that our use of the SafeHandle pattern was not quite right. Native Windows WinHTTP handles wrapped by SafeHandle need additional lifetime management protection to preserve parent-child relationships.

This also simplified the passing of handles to the WinHttpResponseStream class. I added finalizers to the WinHttpHandler and WinHttpResponseStream classes.

" 3105 area-System.Net Avoid blocking CurlHandler write callback When receiving the body of an HTTP response, libcurl provides the data received via a callback that's invoked synchronously from the thread pumping libcurl's processing. This callback can't return until it's handed off all of the available data, and thus the current implementation of CurlHandler blocks that thread until a reader has consumed the data. This is both expensive and dangerous. It's expensive because we end up blocking a thread until some reader comes along, and it's dangerous because this can easily lead to deadlock. A libcurl multi handle may be used by only one thread at a time, which means that if the handle is being used by a thread while blocked on the write callback, no other thread can access the multi handle, which means no other callbacks for other concurrent requests can be invoked. If multiple operations were queued, and then the data for them arrived in an order that didn't exactly match the order of readers consuming the data, deadlock would ensue. This change makes it so that we no longer block the callback, taking advantage of a pausing mechanism libcurl provides that allows one to pause a connection until it's needed. I rewrote the CurlResponseStream to manage this. Now when the callback has data to write, it attempts to transfer it to the stream. If there's a reader already waiting for the data (represented by a task stored on the stream), the callback simply transfers its data to the reader. If the callback has too much data than would fit in the reader, the remaining data is buffered on the stream. If instead the callback finds that either there isn't a waiting task or that there's already some remaining data buffered from a previous callback, it instead pauses the connection, such that no more callbacks will be invoked until we unpause. From the reader side, a reader who tries to read data from the stream can pull data from the remaining buffer if there is any, or can register a task with the stream that will be filled with data at some point when callback has data available. As part of debugging some issues with this change, I added a verbose tracing mechanism that's enabled by compiling the library with the CURLHANDLER_VERBOSE constant (the same that we use for enabling libcurl's verbose diagnostic output). I left the tracing in as I found it valuable in diagnosing issues with the library, but we can remove it later if desired. I also added a test that deadlocks before the change and that completes successfully after. cc: @vijaykota, @kapilash Fixes #3089 3106 area-System.Linq Intersect not optimized for HashSet Hello, I found some old blog about an optimization of Intersect when the underlying collection is a HashSet.

"Please forgive me if this is the wrong place to post this; but it certainly seems like a good place :) I think that it would be extremely useful if there were a general-purpose data binding mechanism providing a consistent way to synchronize the properties of objects making it for developers to have consistent support for patterns that benefit from data binding such as the popular MVVM and MVPVM design patterns. Also including the `IValueConverter` interface and related functionality that is included in the `System.Windows.Data` namespace of the fully featured .NET framework but perhaps in a less platform-specific namespace like `System.Data`? Whilst not applicable in the following example; perhaps a general purpose XAML implementation would also be of benefit perhaps allowing a XAML representation of a custom selection of UI controls outside the scope of Windows or Xamarin forms? I see this being of particular use in .NET Core based game engines. # Example Use Case (User Code) For example, if the Unity game engine was using .NET Core with such a feature it would then be quite straightforward to add binding support to the Unity UI controls simply by having them implement `INotifyPropertyChanged`. ## Programmatic Bindings Continuing with the Unity example; some `MonoView`-derived component could be added to the root of each composition of UI controls allowing for manual binding similar to this: ``` // ExampleView.cs public class ExampleView : MonoView { [SerializeField] private InputField _firstNameInputField; ... protected override void OnBind() { Bindings.Add(new Binding(_firstNameInputField, ""text"", ViewModel, ""FirstName"", BindingMode.TwoWay)); } } ``` Where the base classes look like this: ``` // MonoView.cs public abstract class MonoView : MonoBehaviour { public MonoView() { Bindings = new BindingCollection(); } protected BindingCollection Bindings { get; private set; } ... protected virtual void OnBind() { } protected virtual void OnUnbind() { // Properly disposes all bindings (unsubscribes from source/target objects). foreach (var binding in Bindings) { binding.Dispose(); } Bindings.Clear(); } } // MonoView{T}.cs public abstract class MonoView : MonoView where TViewModel : class { ... } ``` ## Designer Specified Bindings In addition to programmatic binding (like above) it would also be fairly straightforward to create a custom ""PropertyBinder"" `MonoBehaviour` component which could be added to UI controls to allow designers to make similar associations using just the Unity ""Inspector"" window. ``` +---------------------------------------------------------------------------+ | Property Bindings Component: | | +-------------------------------------------------[ Remove Binding ]--+ | | | ___________________________________________ | | | | Control Property: | text | \/ | | | | | ------------------------------------------- | | | | ___________________________________________ | | | | Data Context Property: | FirstName | \/ | | | | | ------------------------------------------- | | | +---------------------------------------------------------------------+ | | _________________________ | | | Add Another Binding | | | ------------------------- | +---------------------------------------------------------------------------+ ``` ## Bindings properly disposed when removed/cleared from the `Bindings` collection When the view is unbound from the data context all `Bindings` would be properly disposed allowing the view to be reused and bound to another view model. # Closing Words I'm sure that you folks have probably already got something like this planned; but I wanted to post this feature request just in case it isn't on the roadmap :) " 3113 area-System.Net Porting System.Net.Security Missing issues for TODO comments.

From reading the various comments - particularly @vancem's https://github.com/dotnet/corefx/pull/2932#issuecomment-134328582 - on the PR I understand that this stems from how RX approaches exceptions, yet in the case of telemetry and multi-cast events it seems like there will be many cases where one broken subscriber shouldn't bring the system down. Would it be possible to consider an overload to `WriteTelemetry` which looks like this: ``` c# public override void WriteTelemetry(string telemetryName, object arguments, Func exHandler) { for (TelemetrySubscription curSubscription = _subscriptions; curSubscription != null; curSubscription = curSubscription.Next) { try { curSubscription.Observer.OnNext(new KeyValuePair(telemetryName, arguments)); } catch (Exception ex) { if (!exHandler(ex)) { break; } } } } ``` This would then support calls that would allow the sender to pass a function that can evaluate for each exception if the calls should continue: ``` c# source.WriteTelemetry(""Send"", o, ex => !(ex is CatastrophicException) ); ``` Alternatively an approach could be considered that uses `AggregateException` that simply collects all exceptions and throws them collectively at the end.

" 3137 area-System.Net CurlHandler synchronously reads from request stream, blocking libcurl processing If the request message has a request content stream to send, libcurl retrieves that data via read callbacks done during its processing. These read callbacks are currently Read'ing from the content stream, which blocks the processing while the read is being completed. If the content stream is a memory stream, this is fine, as such reads will complete immediately. And even for some other stream types, like FileStream, the reads should complete quickly enough that there's no problem. But for streams that take a longer time, this can cause significant delays in CurlHandler's ability to process other pending HttpClient requests. It can also lead to deadlock if the request stream for one request is being fed by the response stream of another request being processed by the same handler. 3138 area-System.Net Avoid blocking CurlHandler read callback PR #3105 addressed the issue we were facing with libcurl and the write callback used when libcurl has response body data available. We were blocking libcurl's callback until a reader was available to consume the data, resulting in both significant scalability issues as well as the potential for easy deadlock. This was fixed by making the whole operation async via libcurl's ability to pause connections. The same issue exists for libcurl's read callback, used by libcurl to read data from the request stream to send as part of the request. The issue here isn't as impactful as on the write side, because a) a common case has no request stream or has a MemoryStream that serves up its data immediately, and b) other streams (e.g. FileStream) typically serve their data quickly even if blocking is involved and don't interact with the HttpClient in a way that could lead to deadlock. However, it's still an issue, and it's still possible to construct cases where deadlock is possible, e.g. if the output stream of one request is used as the input stream of another request associated with the same libcurl multi handle. This commit addresses the read callback case by relying on the same pause mechanism used for the write callback. When libcurl requests data, if the source is a memory stream, we just do the read and hand back the data. Otherwise, we issue a ReadAsync on the stream. If the operation completes immediately, we synchronously hand the data back to libcurl, storing any extra beyond what libcurl asked for. If the operation didn't complete immediately, we store it for later, and pause the connection, requesting an unpause when the read operation completes. Subsequent read requests from libcurl first try to be satisfied from any previous ReadAsync with data remaining. As part of this, I also removed the pause state tracking I'd previously added. In my previous PR as part of adding support for pausing, I added a field to EasyRequest to attempt to mirror the current paused state as known by libcurl. This was done to try to avoid requesting unpausing in cases where we'd like to be unpaused but have already requested it. However, this appears to have been premature optimization, as the case is relatively rare, the overheads relatively low for processing the extra request, and it causes additional headaches once we're able to pause sending/receiving individually. I added several tests for different kinds of streams. This required fixing #3136, which was preventing any data from being sent from non-seekable request streams.

Repro: `Expression.Lambda( Expression.AddChecked( Expression.Constant(Int16.MinValue), Expression.Constant(Int16.MinValue) ) ).Compile().DynamicInvoke()` throws TargetInvocationException with an OverflowException when using the compiler.

It looks like this rule is not honored by the expression compiler which omits the `and` instruction to perform the mask, prior to performing the `shl` or `shr` instruction. The following repros the discrepancy: Expression<Func<long?, int?, long?>> e = (x, y) => x << y; Func<long?, int?, long?> f = (x, y) => x << y; Func<long?, int?, long?> g = e.Compile(); var c = f(-9223372036854775808, -2147483648); var d = g(-9223372036854775808, -2147483648); Console.WriteLine(c); Console.WriteLine(d); Note that the implementation of the expression interpreter relies on C# compiled code fragments for << and >>, so this will cause a different result for .Compile() between frameworks that use the expression compiler versus those that use the interpreter. 3150 area-Infrastructure Cannot build System.Collections.Concurrent.Tests in Visual Studio 2015 I get the following error: ``` xunit.abstractions 2.0.0 is not compatible with DNXCore,Version=v5.0. ``` Any suggestions or work-around? 3151 area-System.Net CurlHandler supports only ClientCertificateOption.Manual Today CurlHandler supports only clientCertificateOption.Manual. Now with the availability of cross platform X509Store, CurlHandler must support ClientCertificateOption.Automatic as well. 3153 area-System.Net Could CurlHandler support UNIX sockets? There is support in `libcurl` for using UNIX sockets instead of TCP (http://curl.haxx.se/libcurl/c/CURLOPT_UNIX_SOCKET_PATH.html). In a microservice world, this capability is very useful for communication between discrete services on a single server, reducing the overhead of TCP sockets and improving performance. As a precedent, the Kestrel HTTP server now supports UNIX sockets, which Nginx can consume when reverse-proxying (see https://github.com/aspnet/KestrelHttpServer/pull/157). I took a quick look to see if I could implement this, but there doesn't seem to be a point where a socket file path could be added in, so I opted for starting a discussion instead. :open_mouth: 3156 area-System.IO Can we determine if a FileSystem is case sensitive or not through an API?

Is there an API can help to determine if a file system at given path is case sensitive. 3163 area-System.Net Replace TRAVE to TRACE_VERBOSE throughout the code. **Workitem:** 1.

See https://github.com/dotnet/corefx/pull/3142#issuecomment-139330591: A general comment on raw integers vs. enum's on C++ side for flags. I've been doing the latter based on my recollection that storing a value that is not any one of the enum members is unspecified or undefined in standard C++. However, I'm no longer sure after looking at recent edits on cppreference.com: http://en.cppreference.com/mwiki/index.php?title=cpp/language/static_cast&diff=78871&oldid=74481 My understanding was on the LHS of that diff. I don't know yet if the edits reflect errata on the site matching my own misunderstanding or just updates tracking the next version of the standard. Even if it is well defined, it requires a lot of ugly casting, which kind of eliminates the benefit of strong typing. It's not apparent in this change because your flags come in from C# with the right values, but once you have to twiddle the bits, e.g. ConvertOpenFlags, it gets messy. Assuming it is in fact well defined, we could have a macro to define bitwise operators on what we deem Flags enums. This would serve double-duty as documentation to C# caller to add [Flags]. I'm fine leaving this for a later change, but this is something we should standardize one way or the other. 3178 area-System.Net Redirect handling for cookies and creds This fix realigns CurlHandler with WinHttpHandler w.r.t Redirect handling.

There’s a default HttpClientHandler type, which on Windows is implemented around winhttp and on Unix is implemented around libcurl. HttpClientHandler only exposes core knobs that are expected to be common across all possible implementations, but the underlying implementations often provide more functionality. So on Windows, we also have System.Net.Http.WinHttpHandler (a class in its own separate assembly), which is the same handler used by default on Windows under HttpClientHandler, but which as a public type exposes additional knobs for developers to configure, e.g. timeouts on individual portions of a request/response rather than for the all-up operation. There are such knobs we’d like to be able to configure with libcurl, e.g. targeting a UNIX domain socket as a proxy, but for which we’d need to expose CurlHandler publically in order to provide the right additional surface area. 3186 area-System.IO Add System.IO.FileSystem.Unix There are a bunch of common Unix file system constructs that we have no public surface area in .NET to control or interact with. For example, Unix permissions are a very common need for users/devs to interact with, but we don’t provide any surface area for getting (stat) or setting (chmod) these. We don’t provide surface area for changing ownership (chown), for creating symlinks (symlink) or hard links (link), etc. Devs can P/Invoke to these, but it’d be nice to have surface area for it to avoid devs needing to do that, especially given that some of these are impractical to P/Invoke to in any common way across Unix systems, e.g. the struct used by stat changes in both layout and size based on which distro/version you’re targeting, which is one of the many reasons we’ve moved away from direct P/Invokes to libc and instead have a think native shim. As a comparison, Mono has a library called Mono.Posix that provides essentially 1:1 wrappers between directly callable C# functions and the underlying POSIX functions they wrap. 3187 area-System.Security Add System.Security.Principal.Unix We provide the Windows-only System.Security.Principal.Windows.dll on Windows, which brings with it WindowsIdentity and WindowsPrincipal. We don’t currently have corresponding types for UnixIdentity and UnixPrincipal. This would support getting the current user/group, setting the effective user/group (kind of like Windows impersonation), looking up information about the user, etc. 3188 area-System.IO Add System.IO.Signals.Unix Signals are a ubiquitous mechanism across Unix systems for interactions between processes and the kernel. The only API we currently have for sending any signal is Process.Kill(), which sends a SIGKILL signal, but to write robust Unix applications (and services) you likely want to be able to both send signals and handle specific signals. The former can be done by a dev using a P/Invoke, but the latter would really require libcoreclr support to do correctly, especially since the runtime itself already hooks certain signals (e.g. a SIGINT signal sent by ctrl-C, which we then subscribe to the runtime for in Console.CancelEventHandler). 3189 area-Meta Add System.Configuration.Unix There’s a lot of Unix configuration information that apps could benefit from being able to read (e.g. sysconf, pathconf, ulimit, etc.) and potentially modify. Potentially support for parsing/outputting Unix configuration files as well. 3190 area-System.Net RemoteCertificateValidationCallback for HttpWebRequest The current implementation of HttpWebRequest in .Net 4.6 lacks RemoteCertificateValidationCallback similar to that of SslStream class. This makes mutual authentication impossible, especially when client becomes aware of mutual authentication enforced by server only after SSL handshake has been initiated. Currently all certificate callbacks for HttpWebRequest is managed by ServicePointManager class, I request to include this feature in corefx releases. Please see [this question](http://stackoverflow.com/questions/9294433/how-to-detect-client-certificate-authentication-request-in-httpwebrequest) in SO. 3199 area-System.Net Reduce allocations when parsing response headers in WinHttpHandler "There are currently many unnecessary allocations when creating the response message in `WinHttpHandler`. The native `WinHttpQueryHeaders` function is called a few times to retrieve response information, such as the version string, reason phrase, and raw headers. Each call to `WinHttpQueryHeaders` currently results in 3 allocations (9 total for the 3 calls): 1. The `StringBuilder` buffer passed to the native function to be filled in. 2. The `char[]` inside the `StringBuilder`. 3. The `string` allocated when `StringBuilder.ToString()` is called. On platforms that need to do manual decompression (lower than Win 8.1), there's another 2-3 allocations to get the Content-Encoding header value. We can reduce the allocations by 1) modifying the p/invoke signature for `WinHttpQueryHeaders` to take a `char[]` instead of `StringBuilder` and 2) allocate a single `char[]` large enough to be reused across multiple calls to `WinHttpQueryHeaders`. With those changes, 9 allocations are down to 2: an allocation for the raw headers `char[]` and another for the reason phrase `string`. There are many common reason phrases, such as ""OK"" for a 200 status code, or ""Not Found"" for a 404 status code. There's already internal code in `HttpStatusDescription` for looking up a known reason phrase string based on the status code, and we can make use of this existing code to avoid the reason phrase string allocation if the reason phrase `char[]` array segment is equal to a known reason phrase. 9 allocations down to 1, for common reason phrases. When parsing the raw headers, the current code is using `string.Split` to split the raw headers by lines separated by `""\r\n""`. There are a bunch of unnecessary allocations associated with the use of `string.split`: internally `string.Split` allocates two arrays to keep track of the indexes and separator sizes, there's the overall array returned from `Split`, plus each string in the array representing each line. Each line then needs to be split further to get the header name and value for each line. The header value was also being trimmed with `string.Trim`, another potential allocation. Also, the first line of the raw headers is the status line, which is being allocated as a `string` even though this line is currently being skipped. All of these intermediate allocations can be avoided by parsing the `char[]` directly, and only allocating `string`s for the individual header names and values. And we can avoid `string` allocations for known header names and values, similar to the known reason phrase optimization. Notes: - `HttpKnownHeaderNames.TryGetHeaderName` is looking up all known header name constants, which include both request and response headers, while we only really care about response headers. My opinion is that this is OK. I think it's easier to maintain the lookup of known headers if it is just looking up all known headers, instead of trying to segregate which ones are only response headers. - `HttpKnownHeaderNames.TryGetHeaderName` is currently doing an ordinal lookup. Header names are case insensitive, so I'd be open to changing this to do an case insensitive lookup. I kept it ordinal so the string remains the exact same as the response string from WinHTTP. However, it looks like WinHTTP normalizes the casing of headers it knows about (e.g. WinHTTP returns `""Content-Length""` when the actual server response is `""content-length""`), so maybe switching to case insensitive lookup isn't a big deal. - The PR is broken up into multiple commits to make it easier to review. The earlier commits are mostly just adding helpers and tests, and moving some of the internal files to `Common` (e.g. `HttpStatusDescription`). I can squash some of the commits together, if desired. - There are still a bunch of allocations associated with how headers are enumerated and stored internally on each request/response in `HttpClient` that I'm looking into improving in a separate PR.

I can provide more details on such scenarios if needed. Unfortunately, expression interpretation is a property of the .NET build flavor, e.g. for .NET Native the Compile method uses the interpreter. It'd be nice to have an Interpret method alongside Compile to enable those scenarios. It'd also help a lot in writing parity tests for the expression compiler and interpreter because their outcomes can be cross-checked. 3245 area-System.Linq Add N-ary internal specializations for InvocationExpression "In Bing, we use an expression normal form whereby method call expressions etc. get erased for invocation expressions of an unbound parameter, e.g.: Expression.Call(where, xs, filter) becomes Expression.Invoke(Expression.Parameter(typeof(...), ""where""), xs, filter) This is done to decouple client libraries and service libraries through erasure of MemberInfo objects. The service uses a binder to bind the unbound parameter expression to a service-side definition and beta-reduces the invocation of the (lambda-based) definition. A lot of those invocation expressions have 0, 1, 2, 3 arguments. However, unlike MethodCallExpression, InvocationExpression has no N-ary specializations that help to reduce memory. The proposal is to add such specializations to conserve memory.

When you run a ""Find Usages"" on `DateTime.UtcNow` in .NET Framework assemblies a lot of usage sites come to light. For example, in ADO.NET, transactions, caches, WebRequest, remoting, WCF, SignalR, security. **All of these usages are bugs** because the current system time can change significantly forwards and backwards at any time. This means that in case the system clock is changed many .NET components will spuriously fail. Common symptoms would be timeouts firing to early or too late (possibly never). Perf counters also might show too high or negative values. Sample scenario: 1. The system clock spuriously jumps forward due to misconfiguration by years. 2. A cache item is added. 3. The clock is fixed. Then, the cache item will essentially stay around forever if eviction is based on `DateTime.UtcNow`. I believe this bug exists in the BCL. User code also has the same problems. **Solution:** Add some kind of monotonic clock to the BCL. The main property of such a clock would be that its time advances linearly. It should never jump when the system clock changes. It should not exhibit split second jumps. It should behave reasonably in case the system sleeps or hibernates or in case the VM is paused. This monotonic clock class should be fast and convenient to use so that it is a no-brainer to switch all `DateTime.UtcNow` usages over to the new model. Maybe we can add `Environment.TickCount64` as well. `Environment.TickCount64` alone would not be good enough because it is awkward to use. I'm not sure if `Stopwatch` would cover all these requirements. It is a reference type which might be too heavy for hot code path in the BCL. Maybe we can add a new value type that is made exactly for this purpose. A sketch: ``` struct MonotonicTime { long Ticks; MonotonicTime operator + (MonotonicTime, TimeSpan); TimeSpan operator - (MonotonicTime, MonotonicTime); bool IsNegative; static MonotonicTime Current; ... } ``` To summarize, I request: 1. The framework timeouts should be fixed. (The TPL bugs apparently are already fixed. I reported these a while ago.) 2. Add `Environment.TickCount64`. 3. Provide a convenient, high-performance monotonic clock. " 3253 area-System.IO Support for tar archives Right now corefx supports zip files as well as gz files.

The language binds to the Expression[] overload. Various tools on our end, such as expression deserializers, also dispatch through the IEnumerable overload. It'd be good for those factories to analyze the number of supplied arguments and use compact representations if available. Also, [Instance]MethodCallExpression0 nodes are missing, even though it's quite common to have such expressions (e.g. ToString). Those could be added as part of this. Note that - in addition to this - it may be possible for the language compilers to check for the N-ary factory method overloads and bind to more specialized overloads when it finds them in the corefx libraries it's compiling against (much like other places where the compiler uses ""feature detection""). This would avoid the Expression[] allocation when it's not needed, therefore reducing some allocation costs.

Verify that CurlHandler behavior is identical to WinHttpHandler in case of negative scenarios. CurlHandler throws parse exception if status code in the Http response is not a valid status code. 3275 area-System.Collections Add a way to start enumeration of SortedSet and SortedDictionary in the middle I'd like an efficient way to start enumeration of a sorted collection (in particular `SortedSet` and `SortedDictionary`) at a specified value. This should work even if the value is not part of the collection. **Why is it useful?** Such a feature would be useful for many things. For example: - Finding all elements in an interval. - Finding the closest element to an item in the set - With a properly chosen comparer prefixes sort immediately before their extensions. So this could be used to find the longest prefix that's in the collection. - Could be used to map from a continuous variable (e.g. time) to a value. For example if a system can either be `on` or `off` at a particular time, one could put the switching evens in a `SortedDictionary` and then query it to figure out if the system was `on` at a particular time. - You could save the current element, mutate the collection (invalidating existing enumerators) and then create a new iterator starting at that element. **Different approaches** One way to implement this feature is having a pair of functions that return an enumerable starting at a particular point in the collection. I'm not sure what the name should be, possible choices include `UpwardsFrom`/`DownwardsFrom`, `From`/`ReverseFrom`, `ForwardsFrom`/`BackwardsFrom`. An alternative approach would be extending `SortedSet.Enumerator` adding a public constructor that takes a start element and a flag for backward iteration, but I don't like that overly low level approach. **A concrete API suggestion** on `SortedSet` ``` public IEnumerable UpwardsFrom(T start); public IEnumerable DownwardsFrom(T start); ``` on `SortedDictionary` ``` public IEnumerable> UpwardsFrom(TKey start); public IEnumerable> DownwardsFrom(TKey start); ``` and optionally on `SortedDictionary.KeyCollection` ``` public IEnumerable UpwardsFrom(TKey start); public IEnumerable DownwardsFrom(TKey start); ``` **Test cases** ``` var sortedSet = new SortedSet{1, 3, 5}; sortedSet.UpwardsFrom(2) // [3, 5] sortedSet.UpwardsFrom(3) // [3, 5] sortedSet.UpwardsFrom(6) // [] sortedSet.DownwardsFrom(4) // [3, 1] sortedSet.DownwardsFrom(3) // [3, 1] sortedSet.DownwardsFrom(0) // [] ``` **Demo implementation** Their behaviour would match the following extension methods, but would avoid the linear scan for the first match: ``` public static IEnumerable UpwardsFrom(this SortedSet sortedSet, T start) { var comparer = sortedSet.Comparer; return sortedSet.SkipWhile(item => comparer.Compare(item, start) < 0); } public static IEnumerable DownwardsFrom(this SortedSet sortedSet, T start) { var comparer = sortedSet.Comparer; return sortedSet.Reverse().SkipWhile(item => comparer.Compare(item, start) > 0); } ``` 3278 area-System.IO Fixed test bug with FileInfo_GetSetTimes resolves #3272 3281 area-System.Diagnostics ProcessTests.TestWorkingSet64 failed on OS X in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx_mac_debug_tst/31/console ``` 21:51:43 System.Diagnostics.ProcessTests.ProcessTests.TestWorkingSet64 [FAIL] 21:51:43 Assert+WrapperXunitException : File path: d:\j\workspace\dotnet_corefx_windows_debug\src\System.Diagnostics.Process\tests\ProcessTests.cs.

The class has number of methods `ToBase64*` and `FromBase64*` with various signatures. The base64 encoding has 8-bit fixed length. The are many applications of variable length base64 encoding; Variable Length Quantity (VLQ). IMO, one of the most popular application of B64 VLQ is in [V3 source maps](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit?pli=1#!); which is used by browsers, editors, trans-compilers etc. to obtain source-to-source mappings in trans-compilation scenarios. For instance; CoffeeScript, Less, Sass, Stylus, SweetJS and TypeScript are languages, that compile into CSS or JavaScript. Today, the developer tools in all major browsers are capable of mapping generated source to original by the virtue of source-maps. Additionally, Base128 VLQ has applications in media formats, such as MIDI, XMF etc. [[1](https://en.wikipedia.org/wiki/Variable-length_quantity)] ### Proposed API: ``` c# namespace System { public static class Convert { [...] public static byte[] FromBaseNVLQString( EncodingRadix radix; string s, BaseNVLQSetting setting); public static byte[] FromBaseNVLQCharArray( EncodingRadix radix; char[] inArray, Int32 offset, Int32 length, BaseNVLQSetting setting); public static string ToBaseNVLQString( EncodingRadix radix; byte[] inArray, BaseNVLQSetting setting); public static string ToBaseNVLQString( EncodingRadix radix; byte[] inArray, int offset, int length, BaseNVLQSetting setting); public static unsafe string ToBaseNVLQString( EncodingRadix radix; byte[] inArray, int offset, int length, BaseNVLQSetting setting); public static int ToBaseNVLQCharArray( EncodingRadix radix; byte[] inArray, int offsetIn, int length, char[] outArray, int offsetOut, BaseNVLQSetting setting); public static unsafe int ToBaseNVLQCharArray( EncodingRadix radix; byte[] inArray, int offsetIn, int length, char[] outArray, int offsetOut, BaseNVLQSetting setting); public static unsafe int ToBaseNVLQCharArray( EncodingRadix radix; byte[] inArray, int offsetIn, int length, char[] outArray, int offsetOut, BaseNVLQSetting setting); } public enum EncodingRadix { Base64 = 64; Baase128 = 128; } public struct BaseNVLQSetting { private int _base, _baseShift, _baseMask. _continuationBit; private char[] separators; public BaseNVLQSetting( int base, int baseShift, int baseMask, int continuationBit, char[] separators); public enum Template { V3SourceMap, MIDI, XMF } public static BaseNVLQSetting FromTemplate(BaseNVLQSetting.Template template) { switch(template) { case Template.V3SourceMap: return new BaseNVLQSetting(1 << 5, 5, 4, 1 << 5, new char[] {',', ';'}); break; [...] default: throw new Exception(""Unknown template.""); } } } } ``` ### Working Example: We implemented sourcemap encoding and decoding in WE2013: [https://github.com/madskristensen/WebEssentials2013/../Base64VLQ.cs](https://github.com/madskristensen/WebEssentials2013/blob/96d37799/EditorExtensions/Shared/Helpers/Base64VLQ.cs), inspired by Mozilla's JavaScript implementation: https://github.com/mozilla/source-map.

Interop.OpenSsl TODO - See if SSL_CTX_Set_quite_shutdown can be used 3364 area-System.Threading ReaderWriterLockSlim.AcquireWriterLock timing out does not wake up waiting readers The [documentation for `ReaderWriterLockSlim.TryEnterWriteLock`](https://msdn.microsoft.com/en-us/library/bb339812.aspx) states: > While threads are blocked waiting to enter write mode, additional threads that try to enter read mode or upgradeable mode **block until all the threads waiting to enter write mode have either timed out or** entered write mode and then exited from it. (emphasis mine). However, the implementation does not behave like the bolded part of the documentation states. Imagine the following scenario with three threads (_T1_, _T2_, _T3_): 1. _T1_ acquires a read lock. 2. _T2_ tries to acquire a write lock and blocks, waiting for a timeout (as _T1_ holds the lock). 3. _T3_ tries to acquire a read lock and blocks (because _T2_ is blocked waiting for the write lock, and per the documentation, this means all further readers are blocked until _T2_ times out). 4. _T2_’s timeout expires. Per the documentation, _T3_ should now wake up and acquire the read lock. However, this does not happen and _T3_ is blocked forever (or, until some other event, e.g. _T1_ releasing the read lock, causes the implementation to wake up waiting threads). [Reproducible code for this scenario is available on StackOverflow](http://stackoverflow.com/a/32656459/304138), with some discussion. AFAICT, this is a simple bug caused by the fact that `TryEnterWriteLock` blocks further attempts to acquire a read lock, but when leaving by timeout, it does not wake them up. Specifically, I’d guess the `ExitMyLock` call in [`ReaderWriterLockSlim’s WaitOnEvent`](https://github.com/dotnet/corefx/blob/master/src/System.Threading/src/System/Threading/ReaderWriterLockSlim.cs#L923) should have been `ExitAndWakeUpAppropriateWaiters`. The same bug seems to exist for the non-slim `ReaderWriterLock`. 3365 area-System.Net Dummy PR with xplat SslStream fixes Sharing some fixes found during unit testing.

Consider system where some strings are case sensitive (e.g. hash), and some aren't (e.g. name). Currently .NET defaults to being case sensitive, so I have to remember which string is which in all use cases. And those cases are not only about `s1.Equals(s2)` -- it is also every call to `ToDictionary`, every creation of `HashSet` and various other cases and optimizations that are really hard to keep track of. It would be great if I could define string as being case-insensitive on type level, e.g. use `CaseInsensitiveString`. This would affect Comparer selection wherever this type is used as a key, and all comparisons. Not quite sure whether it makes general sense and what the API would be like, so just putting it here as a discussion point. 3419 area-System.Runtime StringBuilder.AppendJoin (appending lists to StringBuilder) "#### Background Let's say you want to build a string that contains a separated list (e.g. list of filenames, messages, or anything else). If it is the only thing you want, you can use `string.Join`. However what if you want to append something else? If you `Concat` with the result of `string.Join`, that means that you unnecessarily allocated an intermediate joined string, which can be rather large (depending on the original collection). On the other hand, `StringBuilder` would require something like: ``` csharp var builder = new StringBuilder(""Names: ""); for (var i = 0; i < names.Length; i++) { if (i > 0) { // this becomes even more involved if `names` is `IEnumerable` builder.Append("", ""); } builder.Append(names[i]); } ``` That can be abstracted into an extension method, however I believe that extension would be general and useful enough to benefit from being in NetFX. #### API Design (updated based on API review, second pass -- see https://github.com/dotnet/corefx/issues/3419#issuecomment-273254581) ``` csharp public class StringBuilder { public StringBuilder AppendJoin(string separator, params object[] values); public StringBuilder AppendJoin(string separator, IEnumerable values); public StringBuilder AppendJoin(string separator, params string[] value); public StringBuilder AppendJoin(chat separator, params object[] values); public StringBuilder AppendJoin(char separator, IEnumerable values); public StringBuilder AppendJoin(char separator, params string[] value); // string.Join overloads NOT taken: //public StringBuilder AppendJoin(string separator, IEnumerable values); //public StringBuilder AppendJoin(string separator, string[] values, int startIndex, int count); //public StringBuilder AppendJoin(char separator, IEnumerable values); //public StringBuilder AppendJoin(char separator, string[] values, int startIndex, int count); // REJECTED in the first API review round: //public StringBuilder AppendJoin(string separator, T[] values, int startIndex, int count); //public StringBuilder AppendJoin(string separator, params T[] values); //public StringBuilder AppendJoin(char separator, params T[] values); } ``` Note: Motivation for the API approval update is described in https://github.com/dotnet/corefx/issues/3419#issuecomment-273254581 -- adjusting to follow proven working form of 'string.Join', correctly working with most-used overload calls - see usage example in https://github.com/dotnet/corefx/issues/5552#issuecomment-268395367. #### Compatibility Potential source-level issue if someone is already using an extension method with the same name.

[Back on May 5th](https://github.com/dotnet/corefx/issues/1039#issuecomment-99186515) @davkean noted: > We want GetSchemaTable in some form (we should get a separate bug filed on that, however, as you could imagine bringing that back with a different design that doesn't pull in DataSet/DataTable). While it doesn't seem that anyone cares _what method_ exists for of getting the schema of a resultset, we seem to agree on needing _a method_ of doing it in .Net Core. For example, if a user runs a simple query such as: ``` SQL SELECT 'bob' Name, 1 Id ``` Then there's no way to see what the types are. While getting the .Net type ([via `.GetFieldType()`](https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.getfieldtype%28v=vs.110%29.aspx), e.g. `DateTime`) is possible and getting _part_ the SQL type ([via `.GetDataTypeName()`](https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.getdatatypename%28v=vs.110%29.aspx), e.g. `NVARCHAR`) is possible, other vital attributes of the schema shape currently aren't possible. For example there's no way to distinguish a `varchar(20)` from a `varchar(max)`. There's also no way to tell if the column was nullable. Previously, this functionality was provided by [`.GetSchemaTable()`](https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldatareader.getschematable%28v=vs.110%29.aspx) which returned a [`DataTable`](https://msdn.microsoft.com/en-us/library/system.data.datatable%28v=vs.110%29.aspx) class. Currently I have a very simple use case: query data here, create a table with that data elsewhere. The query can be something like: `SELECT * FROM sys.database_files`. I point this out to illustrate that `INFORMATION_SCHEMA` (as proposed by some in #1039 as an alternative) is not a viable option. The same issue presents on any stored procedure which can also return any result set shape depending on the code paths. We need a way to see the scheme _of a result set_, these database-query alternatives are both expensive and non-covering. This is a hard blocker for projects of myself and others. I have uses in both one-off projects as well as [Opserver](https://github.com/opserver/Opserver) (which monitors SQL) and [Dapper.Net](https://github.com/StackExchange/dapper-dot-net). I know from #1039 that I'm not alone on this block. The portability of .Net core is _extremely_ appealing for certain projects, especially those where we need to monitor the innards of SQL without depending on a .Net install (many if not most existing SQL servers only have .Net 3.5). Unfortunately though, this one missing piece of the puzzle may prevent using it altogether, forcing full CLR installs. While SqlClient specifically serves my blocking use case, it's important to point out as @FransBouma [notes in the other issue](https://github.com/dotnet/corefx/issues/1039#issuecomment-142202400): this needs to be in the base API, not specifically up in SqlClient. For example, I also need this for Dapper features and it works across many providers - it is not at all SQL Server specific. So how about it, can we please get an API for result set schemas added back? I'm happy to contribute to designing and provide feedback on a new API here if that's the best route. I know many others are as well. 3425 area-System.Net Testing SslStream Read/Write logic 3431 area-System.Net Unix SslStream needs to verify the remote cert is valid for the destination address 3432 area-System.Net Adjust the PAL separation for certificate verification The Windows version requires that there be a valid handle to the native chain representation; the Unix version never has a valid native handle.

As of a couple weeks ago we still got the TimeOutException but the elapsed time seemed to correlate to however long it took for the call to return from the service operation. So if the ‘SendTimeout’ was set to 5 milliseconds and the service operation waited 30 milliseconds to return, the elapsed time would be something over 30 milliseconds.

But in the new API, most of the main methods are not virtual or abstract. On DbCommand alone we can see this: ``` cs public DbConnection Connection { get; set; } public DbParameterCollection Parameters { get; } public DbTransaction Transaction { get; set; } public DbParameter CreateParameter(); public Task ExecuteNonQueryAsync(); public DbDataReader ExecuteReader(); public DbDataReader ExecuteReader(CommandBehavior behavior); public Task ExecuteReaderAsync(); public Task ExecuteReaderAsync(CommandBehavior behavior); public Task ExecuteReaderAsync(CommandBehavior behavior, CancellationToken cancellationToken); public Task ExecuteReaderAsync(CancellationToken cancellationToken); public Task ExecuteScalarAsync(); ``` While these methods can certainly be made virtual or abstract, it would be much more useful to have the real interfaces back, and make any public API depend on these interfaces instead of the abstract classes. This is mostly useful when developing libraries. Today it's very hard to mock a datareader to make it return a specific value for testing purposes. The same for ensuring that ExecuteReaderAsync was called, not ExecuteReader, etc. I propose the provider factory instead should be made as an interface: ``` cs public interface IDbProviderFactory { IDbCommand CreateCommand(); IDbConnection CreateConnection(); IDbConnectionStringBuilder CreateConnectionStringBuilder(); IDbParameter CreateParameter(); } ``` And then follow from there to the rest of the provider to things like `IDbDataReader`, `IDbTransaction`, etc. We know the interfaces became out of sync for some reason in the past and the abstract classes were made the official API, but this doesn't need to be the case anymore in corefx. Note that this doesn't mean removing the System.Data.Common in any way, but instead make the Common classes implement these interfaces, and you wouldn't use System.Data.Common unless you're implementing the provider. Applications would depend only on the interfaces instead. Please consider this to make the API more testable on corefx 1.0. Related to discussions on #1039 and #3423. 3481 area-System.Linq How best to implement Linq's iterators. The current approach with `System.Linq.Enumerator`'s enumerables and their enumerators copies the approach for compiler-generated iterators; the same instance that serves as the enumerable serves as the result for the first call to `GetEnumerator()`, so avoiding an extra allocation. There is a race inherent to this approach; if two threads called `GetEnumerator()` at the same time they could end up with the same object when they should have separate instances. This is resolved by capturing `Environment.CurrentManagedThreadId` on construction and only using `this` as the result of `GetEnumerator()` if it matches a second call. This relatively expensive call is of no value if: 1. `GetEnumerator()` is never called (many optimisations skip it in various ways). 2. `GetEnumerator()` is repeatedly called (after the first call). 3. `GetEnumerator()` is only called once, on another thread (e.g. if a query is constructed before an `await` and enumerated after it). #3313 changes the approach to changing the state with `Interlocked.CompareExchange()` to resolve the race in a different way. This means no call in case 1 and 3 above, but is more expensive in case 2. It's about even in the case of one `GetEnumerator()` at least as some tests with Win64 DNX suggest (`CompareExchange` being about twice the case of `CurrentManagedThreadId` and being called half as often). In the discussion on that pull request, @Vsadov points out that the optimisation of avoid an allocation may not be as valuable as it once was in any case. Some very limited experimentation suggests that indeed just creating a new object on every call to `GetEnumerator()` is a clear win. There are a few possible variants here. We can have the same classes that server as both enumerable and enumerator, or separate classes (some reduction in state held, some increase in jitted code). If separate classes are used, internal calls to `GetEnumerator()` can be moved to this object's construction, further reducing state held in some cases, but being an observable change if that call throws an exception. A completely different possibility is to use the current approach, but avoid calling CurrentManagedThreadId is some cases. Some experimentation is in order. Some possible approaches: 1. Leave things as they are. 2. Use the basic approach currently used, but avoiding the `CurrentManagedThreadId` call, https://github.com/JonHanna/corefx/tree/fewer_threadid_calls 3. Use `Interlocked.CompareExchange()`: https://github.com/JonHanna/corefx/tree/defer_obtaining_threadid 4. Use the same classes as currently, but always allocating for `GetEnumerator()`: https://github.com/JonHanna/corefx/tree/fresh_enumerators 5. Use separate enumerators https://github.com/JonHanna/corefx/tree/separate_enumerators_cautious 6. ~~Use separate enumerators, shifting `GetEnumerator()` calls (observable change) https://github.com/JonHanna/corefx/tree/separate_enumerators~~ I'm planning to do some comparisons with these variants, but I'm opening this issue ahead of that for suggestions as to situations the comparisons must cover. In particular: Is 6 (with the observable change) completely out of the question? What tests would one expect avoiding an allocation to do better than not avoiding it? (First brief experiments suggest it's always a lose, but I'm wary of removing what was clearly intended as an optimisation if I can't see where it succeeded in optimising, though maybe it's just a matter of older CLR versions). 3482 area-System.Collections Proposal: (I)Dictionary.GetValueOrDefault ## Scenario In almost every app or library I write I almost always end up needing to write code like this, in at least one place: ``` c# SomeClass returnValue; return DictionaryOfSomeClass.TryGetValue(someKey, out returnValue) ? returnValue : null; ``` The reason that the `IDictionary` contract throws from its indexer for a non-existent key are well-known: an alternative behavior of returning `null` is nonsensical if `TValue` is a value type. Returning `default(TValue)` would work, but would clearly be a misleading behavior. But with dictionaries of class-types it is often desirable and expected to return `null` for a non-existent key. ## Proposal ```c# namespace System.Collections.Generic { public class Dictionary { public TValue GetValueOrDefault(TKey key); public TValue GetValueOrDefault(TKey key, TValue defaultValue); } public static class CollectionExtensions { public static TValue GetValueOrDefault(this IDictionary dictionary, TKey key); public static TValue GetValueOrDefault(this IDictionary dictionary, TKey key, TValue defaultValue); public static TValue GetValueOrDefault(this IReadOnlyDictionary dictionary, TKey key); public static TValue GetValueOrDefault(this IReadOnlyDictionary dictionary, TKey key, TValue defaultValue); } } ``` **Notes:** - There will be source-compile problem with ambiguity in all projects that already have such custom extension method `GetValueOrDefault` on `IDictionary` or `IReadOnlyDictionary`. Which is general problem for any extension method we add into CoreFX. ### Original Proposal - replaced by the one above I propose the following extension method (I don't like the name `GetValueNoThrow`, so that can be ignored for now). Please note that it applies only when `TValue` is a class, so it does not violate any behavior for value types. ``` c# public static class ClassyDictionaryExtensions { public static TValue GetValueNoThrow_Ignore_The_Name(this IDictionary dictionary, TKey key) where TValue : class { if (dictionary == null) { throw new ArgumentNullException(nameof(dictionary)); } TValue value; dictionary.TryGetValue(key, out value); return value; } } ``` The new code would end up with one very-easy-to-read line of code: ``` c# return DictionaryOfSomeClass.GetValueNoThrow(someKey); ``` ## Discussion Would others find such an extension method useful? 3483 area-System.Console Add an API to execute a console program and capture its output in a simple way Clearly, we can use the `Process` class to run a program, redirect its output and capture the output. But doing so correctly is unfathomably complicated: 1. You need to read both StdOut and StdErr. Failing to do so can result in hangs. 2. Output events can arrive _after_ WaitForExit has returned. (Update: This concern does not exist.) 3. Output events signal their completing by sending one `null` string at the end. 4. `myProcess.StandardOutput.ReadAsync` throws an exception for the last read with a confusing message (http://stackoverflow.com/questions/32800802/unable-to-read-output-from-child-process-from-c-sharp-app-using-async-methods#32800802). 5. Reading binary output requires contortions (`myProcess.StandardOutput.BaseStream`) where it is not clear whether this is supported at all. We are reaching into the `BaseStream` property which might expose an internal object not meant for consumption. 6. Failing to quickly read the redirected streams stalls the child process. 7. Many more on this list: http://csharptest.net/321/how-to-use-systemdiagnosticsprocess-correctly/ 8. Probably, even more that are on nobodies list. This API is terrible! Please provide an easy and reliable way to capture output. Here's a strawman for a simple API `IEnumerable Process::StartWithOutputRedirected()` Now, this clearly is insufficient and probably not nice API design but you get the point. The following goals should be achieved: 1. Little potential for mistakes. 2. Streaming output for unbounded output size. 3. Text and binary output. 4. Differentiate between StdOut and StdErr. For example by returning an `IEnumerable` of a DTO like `struct ConsoleOutput { string Data; ConsoleOutputType Type; /*Output, Error*/ }`. 5. The output stream should end at exactly the same point in time that WaitForExit ends at. Delay both to only complete when the other also has completed. 6. The API should allow reading in a non-linewise fashion. 7. A simplified version that just captures all output on both channels into one `string`. This is probably what most consumers want anyway. 3484 area-System.Net Some asserts during X-Plat Sockets Tests See: http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst/1021/console.

" 3538 area-Infrastructure Discussion regarding support of CoreFX builds on non-windows OSes. "Today, building CoreFX on non windows platforms uses Mono as the runtime for all the managed code we need to run (namely MSBuild and Roslyn). The long term goal is to instead run on-top of a stable CoreCLR build. However, making this change has the possibility to regress supported build platforms since CoreCLR may not run everywhere Mono does (e.g. FreeBSD, other linux Distros, etc.) As a concrete example, our tool runtime package (which we would use to run GenFacades) contains a CoreCLR which only supports Ubuntu 14.04[1](#fr1). With buildtools 97 we are at the point now where we can actually enable GenFacades and have it work on Ubuntu 14.04, but doing so will break the build on incompatible distros. The question is, do we care enough to spend engineering effort to allow the build to work on platforms that we don't have a supported CoreCLR package for? Do we expect that when MSBuild on .NET Core lands and we try to adopt it that we will remove our mono dependency entirely? What does that mean for folks like the FreeBSD port team (/cc @janhenke), who want to build our stack on FreeBSD while they bring things up if we don't have FreeBSD packages? I know that @pgavlin is chomping at the bit to get more of the build working on Linux. It would be helpful to me as well, but we need closure here before we start going making changes that might break folks. I see a few paths forward. 1. Say that building Managed CoreFX code cross platform requires your platform be supported by CoreCLR. Since today the supported platforms are Ubuntu 14.04 and OSX, update build.sh to pass the correct RID for ToolNugetRuntimeId when invoking MSBuild. If you are on a different distro and want to go out of your way to install the correct set of dependencies so an existing supported RID can run on your distro, you're free to do so and then use that RID. 2. Do platform detection and ""light up"" when we are running on a CoreCLR supported distro. In this mode, if we are able to run CoreCLR, we prefer that otherwise we fallback to Mono. For cases where we can't fallback (e.g GenFacades) we just no-op the relevant builds tasks. 3. Make the statement that managed code that runs during build time _must_ run on Mono and _may_ run on CoreCLR. This is like (2) expect it means we can always fallback. This is not true today. I'm interested in getting everyone's take on this. Maybe I'm freaking out over nothing and I can go ahead and just do (1) without anyone getting upset. 1 Technically, this could mean any OS that has a set of libraries which are binary compatible with the versions of our dependencies in Ubuntu 14.04. For some dependencies this is easy (i.e. the version of openssl that is in another distro's package manager is probably binary compatible with the version in Ubuntu 14.04, but the version of the ICU library is probably not, since they decorate their export names per version).

It seems like the long term plan is that we move to @ianhays's [Performance] stuff. Can we just adopt these changes for that instead of having yet another perf testing thing that also runs inner loop? /cc @CIPop @davidsh @pgavlin @bartonjs. 3543 area-Infrastructure Repo organization guidelines for Common\tests Currently, there's a free-for-all regarding how code is placed in `src/Common/tests` folders, unlike the `src/Common/src` folder tree which has clear guidelines. There are a few proposals: 1) Mirror the `src/Common/src` idea and have everything properly aligned to the namespace. So, the folder paths would look like this: `src/Common/tests/System/Net/Http/HelperClass.cs`. Note that each namespace path is one word only per part in the pathname. This seems to be the most logical choice although. It could create some confusion at first since, for example, Sockets tests will add to Threading, EventSource and Resources but in the end will allow for better organization, review and increase code reuse. 2) Organize `src/Common/tests` per namespace ownership: /System.Net; /System.Xml, etc. So, the folder paths would look like this: `src/Common/tests/System.Net.Http/HelperClass.cs` This is partially what's going on today although there are folders that aren't fully specifying the namespace such as Collections, Compression, etc. Please add your opinions. 3544 area-System.Globalization "[Linux] Default locale is ""Invariant Language (Invariant Country)""" "Odd default locale with Core CLR on Linux: It is the invariant locale rather than the expected ""English (United States)"". Test just examines `Culture.CurrentCulture.EnglishName` and `Culture.CurrentUICulture.EnglishName`. Mono gets this right on the system system. I'm using `System.Globalization/4.0.11-beta-23326`, `System.Globalization.Extensions/4.0.1-beta-23326` and `System.Runtime/4.0.21-beta-23326` for most-recent tests of this scenario. " 3546 area-System.Linq Stack overflow enumerating EnumerableQuery created from null enumerable `EnumerableQuery` can be created passing null a `Expression`, an inappropriately typed `Expression`, a null `IEnumerable`, or a null value of a derived type. Blocking this would be a breaking change, especially since such objects can be usefully used as query providers. Calling `GetEnumerator()` on most such cases result in an `ArgumentNullException` or `ArgumentException`, which could probably be improved (another exception might be more appropriate), but if the constructor was passed a null `IEnumerable` then `GetEnumerator()` hits two cases where it would go into infinite recursion. First when the expression is visited, it is then recursively visited again until stack overflow. Potentially there are other ways this path could be hit, and so other bugs it could cause. If this is fixed, then `GetEnumerator()` itself will then delegate to its own `GetEnumerator()` causing infinite recursion again. ``` C# [Fact] public void NullEnumerableConstantNullExpression() { IQueryable query = new EnumerableQuery((IEnumerable)null); var exp = (ConstantExpression)query.Expression; query.GetEnumerator(); // stack overflow. } ``` 3548 area-System.Net Move Sockets performance tests into [OuterLoop].

However, one omission is a concurrent equivalent for `System.Collections.Generic.HashSet`. At the moment, if a thread-safe hash set is needed, we are left with one of three options: - Creating a thread-safe collection class from scratch. - Synchronizing `System.Collections.Generic.HashSet` in a wrapper class. - Using `System.Collections.Concurrent.ConcurrentDictionary` with ""dummy"" values such as `object` or `byte`, either directly or through a wrapper. None of these approaches is ideal. The first and second option are both error prone (concurrency is hard) and difficult to fully optimize. The third wastes memory and time spent allocating the dummy objects. It seems reasonable to expect such a class wouldn't be too challenging to create given that it would appear to mostly consist of reducing the functionality in the already-existing `ConcurrentDictionary` class (though that one is ~2,000 line long, so...).

Consider the following sequence of events for a SocketAsyncEventArgs `args` and a non-null `byte` buffer `buf`: 1. `args._buffer` is set to `buf` via `args.SetBuffer(buf, 0, buf.Length)` 2. Some asychronous call is made using `args` (e.g. `socket.SendAsync(args)`) 3. The asynchronous call completed 4. `args._buffer` is set to `null` via `args.SetBuffer(null, 0, 0)` 5. A GC occurs that relocates `buf`. 6. `args._buffer` is reset to `buf` via `args.SetBuffer(buf, 0, buf.Length)` 7. Another asynchronous call is made using `args` (e.g. `socket.SendAsync(args)`) - (2) will pin `buf` via a `PreAllocatedOverlapped` instance, store the instance in `args._preAllocatedOverlapped`, set `args._pinState` to `PinState.SingleBuffer`, set up a native overlapped object, and finally set `args._ptrNativeOverlapped` to a safe handle that wraps the overlapped object. - (3) will dispose the handle stored in `args._ptrNativeOverlapped` and set `args._ptrNativeOverlapped` to `null`. - (4) will call `args.FreeOverlapped`, which will dispose `args._preAllocatedOverlapped` (thus unpinning `buf`) and set `args._preAllocatedOverlapped` to `null`. `args._pinState` and related fields will not be updated: the code that does so is conditional upon `args._ptrNativeOverlapped` being non-`null`, and (3) already set the same to `null`. - (6) will call `args.CheckPinSingleBuffer`, which will observe that `args._pinState` is `PinState.SingleBuffer` and `_pinnedSingleBuffer` is the same as `_buffer` and consider the buffer already pinned. As a result, the call will not re-pin `buf`. - Because (6) did not re-pin `buf`, the asynchronous call made in (7) will reuse the address at which the buffer was located the last time it was pinned. At best, this address is no longer mapped and the call results in an AV; at worst, this address contains unknown (and potentially sensitive) data. The fix is to reset `_pinState` and related fields when `_preAllocatedOverlapped` is disposed. 3576 area-Infrastructure Is there a Resharper settings file for this coding style?

"A lot of `System.Composition` code has been [merged recently](https://github.com/dotnet/corefx/pull/1851), and lines up with the MEF 2 code from codeplex. Is any of the code from `System.ComponentModel.Composition` likely to be integrated? I have an old codebase that I've been refactoring and splitting out into separate components, and for some scenarios, I've had to use `System.ComponentModel.Composition` instead of the `System.Composition` package available from Nuget. The main justification behind our switch was that the `CompositionContainer` supports `ComposeExportedValue(T exportedValue)` while the `CompositionHost` doesn't. Being able to explicitly export an _existing_ object instance can be useful when the full architecture isn't adjustable. While it's not exactly the purest of approaches, in some scenarios a little flexibility goes a long way. `System.Composition` [""has been optimized for static composition scenarios and provides faster compositions""](http://mef.codeplex.com/). There are some scenarios where the alternative structure is a better fit, if less streamlined. We've also considered making this project cross-platform, which makes its presence in the OSS .NET Core desirable for us. I bring this up because `System.ComponentModel` is [marked as ""done"" on the progress chart](https://github.com/dotnet/corefx-progress/blob/master/src-diff/README.md), but `System.ComponentModel.Composition` isn't listed at all. With the integration of `System.Composition`, I'm concerned that this is something that's not even being considered and it might end up ignored by default. This also brings up the concern of whether merging namespaces would be feasible. Having multiple namespaces around isn't exactly ideal from a usability perspective, but changing them would be a compatibility issue. It's also possible that there's some code duplication between the two, at least as far as the attributes go. Discarding the old namespace for us is feasible - we want it for the functionality, but we're not attached to the namespace and are open to recompiling. If I've somehow missed the introduction of equivalent functionality, please enlighten me. " 3638 area-System.Net Fixed Renegotiate & sslV3 issue in System.Net.Security xplat. Made op… 1.

Sample Repro: ``` public static void Main() { System.Security.Principal.GenericIdentity identity = new System.Security.Principal.GenericIdentity(string.Empty); } ``` The difference is a change in the way the System.Security.Claims.Claim constructor works - the empty string (valid value in desktop) is now treated the same as null (an invalid value), and therefore the call fails with the exception below ``` System.ArgumentNullException : Value cannot be null.

While in other Streams the `.Flush()` call will ensure that all the data is written, it is not the case for `GZipStream` and `DefrateStream`. For example if we modify `RoundtripCompressDecompress` in the `System.IO.Compression.Tests` project in the following way, all tests using it will fail. ``` csharp private async Task RoundtripCompressDecompress(bool useAsync, bool useGzip, int chunkSize, int totalSize, CompressionLevel level) { byte[] data = new byte[totalSize]; new Random(42).NextBytes(data); var compressed = new MemoryStream(); var compressor = useGzip ? (Stream)new GZipStream(compressed, level, true) : new DeflateStream(compressed, level, true); { for (int i = 0; i < data.Length; i += chunkSize) // not using CopyTo{Async} due to optimizations in MemoryStream's implementation that avoid what we're trying to test { switch (useAsync) { case true: await compressor.WriteAsync(data, i, chunkSize); break; case false: compressor.Write(data, i, chunkSize); break; } } } compressor.Flush(); compressed.Position = 0; var decompressed = new MemoryStream(); var decompressor = useGzip ? (Stream)new GZipStream(compressed, CompressionMode.Decompress, true) : new DeflateStream(compressed, CompressionMode.Decompress, true); { if (useAsync) decompressor.CopyTo(decompressed, chunkSize); else await decompressor.CopyToAsync(decompressed, chunkSize, CancellationToken.None); } decompressor.Flush(); Assert.Equal(data, decompressed.ToArray()); compressor.Dispose(); decompressor.Dispose(); } ``` That means that `GZipStream` & `DefrateStream` will not finish writing until they are effectively disposed (which could take some time if `.Dispose()` is not called immediately) and may also fail if chained.

The ""httpbin.org"" server also has a bug where it does not properly echo chunked upload headers which was causing issues when trying to port these tests. I did not change other networking tests still using ""httpbin.org"" and the Common HttpTestServers class. I will be doing that later as we finalize the test infrastructure.

The PostgreSQL protocol, for example, needs to send each single SQL statement as a separate protocol message, forcing Npgsql to split CommandText by semicolon at the client side, a pretty complex task (need to understand when the semicolon is quoted, etc.). It would be much better to provide a list-based API, where the user provides, say, an array of strings. A specific provider can still choose to join by semicolon if needed, but this should be done at the provider level rather than by the user. For backwards compatibility, the CommandText property would still support the legacy semicolon batching mode. A boolean LegacyBatchingMode connection string parameter, true by default, could be turned off to disable it (thereby removing the client-side SQL parsing in Npgsql, etc.).

This is failing because it is trying to rewind a non-rewindable stream. BUT it shouldn't be attempting that. It shouldn't need to rewind the stream because the POST should succeed right away. This tells me that the .PreAuthenticate feature in the Linux version of the Handler (CurlHandler) is broken. The test is issuing a HEAD request first which should ""warm up"" the authentication for the .PreAuthenticate=true. But it looks like it is broken. Also, the CurlHandler should NOT be rewinding the stream on its own. Only the HttpContent class do that as part of the contract for SerializeToStreamAsync(). See StreamContent.cs in the Http Library. I see that the Linux code might be calling Seek to rewind the content to re-POST it. That itself shouldn't happen because only the StreamContent class is responsible for rewinding itself. The handlers are NOT supposed to rewind the content on their own. I suspect that the CurlHandler is doing this because one of the tests is failing with a CurlHandler specific message: ""Send failed since rewinding of the data stream failed"". That code probably needs to change in CurlHandler. There shouldn't be a separate string resource for this error since CurlHandler shouldn't be rewinding content.

According to the docs, ""this function gets called by libcurl to seek to a certain position in the input stream and can be used to fast forward a file in a resumed upload (instead of reading all uploaded bytes with the normal read function/callback). It is also called to rewind a stream when data has already been sent to the server and needs to be sent again. This may happen when doing a HTTP PUT or POST with a multi-pass authentication method, or when an existing HTTP connection is reused too late and the server closes the connection."" We implement that callback by checking if the Stream's CanSeek is true, and if it is, calling Seek, otherwise we inform libcurl that the Stream isn't seekable: > https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/Unix/CurlHandler.MultiAgent.cs#L851-L859 > What would you recommend we do here instead? The CurlHandler is not supposed to be rewinding the HttpRequestMessage.Content streams. It should be simply using the HttpContent contract APIs to tell the HttpContent to ""serialize"" itself. The HttpContent object is responsible for determining how to do that. The CurlHandler should not be directly retrieving a stream from the HttpContent. Instead the HttpContent is told to serialize itself to a some ""Http Request Stream"". And it does that via the its `CopyToAsync` method. See code in WinHttpHandler for example: ``` c# // Send request body if present. if (state.RequestMessage.Content != null) { using (var requestStream = new WinHttpRequestStream(requestHandle, chunkedModeForSend)) { await state.RequestMessage.Content.CopyToAsync( requestStream, state.TransportContext).ConfigureAwait(false); requestStream.EndUpload(); } } ``` " 3700 area-System.Net Increasing timeout values for sockets tests.

In the full Framework, the base Stream exposes these methods as well, as virtual, and NetworkStream's override the base ones. Then the base Stream's ReadAsync/WriteAsync implementations use these for their implementation, which means NetworkStream gets at least a basic async ReadAsync/WriteAsync implementation ""for free"". In corefx, however, Stream doesn't expose the Begin/End methods, which means NetworkStream's Begin/End methods don't override them, which means NetworkStream's ReadAsync/WriteAsync methods are currently just using the base implementation that queues a work item to call the synchronous Read/Write methods. That's far from ideal for a stream focused on I/O with high latency. This commit just adds basic implementations of NetworkStream.ReadAsync/WriteAsync that use TPL's FromAsync methods to delegate to the Begin/End methods, very similar to how the base class would have. There are currently no unit tests for NetworkStreamin the repo, so I haven't added any yet for these new methods. However, there is an existing functional test that does use ReadAsync/WriteAsync, so they're getting at least some coverage. cc: @cipop, @davidsh, @pgavlin " 3711 area-System.Net Beta 8 blocker: System.Net.Security nuget package authoring needs to be updated to support xplat Same issue as https://github.com/dotnet/corefx/issues/3709 only for System.Net.Security.dll /cc @bartonjs @chcosta @ericstj 3715 area-System.Net Pending features/comments in xplat NegotiateStream 1.1 Get the correct library to use on OSX and update Interop.Libraries.cs 3716 area-Meta Inconsistent versioning When you build the CoreFX assemblies and you put them altogether, you realize that there are some inconsistent version number.

when libcurl needs to rewind the stream, CurlHandler seeks on the stream. Unfortunately, it turns out ReadAsStreamAsync isn't actually intended to be used by handlers in this manner, and as such there are some deficiencies that lead to correctness problems. For example, some of the WCF HttpContent-derived types return non-seekable streams from CreateContentReadStreamAsync and thus from ReadAsStreamAsync. This means that, using ReadAsStreamAsync, if we need to resend a request, we need to call ReadAsStreamAsync again. But ReadAsStreamAsync doesn't do the same _contentConsumed check that SerializeToStreamAsync does. That means if the content is actually a StreamContent, whose CreateContentReadStreamAsync just does `return Task.FromResult(new ReadOnlyStream(this._content));`, and if the stream is non-seekable, then we'll end up getting back the ""new"" stream but that's already had its content consumed, and we won't know. We can't even try to do an object reference comparison, because StreamContent is wrapping the returned stream in a new ReadOnlyStream instance each time. The recommended approach for handlers is to use HttpContent.CopyToAsync. CopyToAsync is a push-based model, letting the HttpContent write to a target stream. CurlHandler/libcurl have a pull-based model, with CurlHandler ReadAsync'ing from the request content based on callback from libcurl. To straddle this divide, this commit adds a specialized push/pull adapter stream that let's CurlHandler effectively read from the pushing source. If/when libcurl asks to rewind, the stream resets itself by doing a new CopyToAsync operation. This revised approach does incur more costs, however care has been taken to try to minimize those overheads as much as possible, and the change is necessary for correctness. This PR also fixes an issue with regards to which exception type CurlHandler wraps.

The PAL design is similar to the one @pgavlin designed for System.Net.Primitives, NameResolution and Sockets: partial static classes replaced the interface/class/factory pattern that was derived from the SSPI object model. Semantics should remain the same. 1. \CertModule.cs was renamed to CertificateValidationPal..cs. CertWrapper and CertInterface have been removed. 2. \SSPISecureChannelType.cs was renamed to SslStreamPal..cs. Modified GlobalSSPI, SSPIInterface have been removed temporarily. The plan is to add them back with the original semantics for NegotiateStream support via Win32 SSPI. - Small change in QueryContextChannelBinding to simplify the PAL. - Added a static readonly sync object in the Windows implementation to preserve interlocked behavior. - Removed Win32Exception from MapToSecurityStatus. (Still needs to be redesigned to avoid string parsing.) 3. Rest of * have been moved to Interop. I did my best to integrate with the latest sources in master. 4. Removed NegotiateStream / Auth code.

CoreFX-Unix is emitting (and expecting) the signature block: ``` ECDSA-Sig-Value ::= SEQUENCE { r INTEGER, s INTEGER } ``` These values will never be equal, differing by the ASN/DER structural information.

Hi all, I've been following the various conversations regarding graphics in corefx: #1563, #489, etc and also following the progress of the library in corefxlab https://github.com/dotnet/corefxlab/tree/master/src/System.Drawing.Graphics and I'm still left wondering what the overall plan is. Progress in the lab repo seems to have stopped and there seems to be no further discussion I can find anywhere on what is happening. I'm the primary author of the project [ImageProcessor](https://github.com/JimBobSquarePants/ImageProcessor/) which I wrote to make System.Drawing a little easier to work with. It's been fairly successful in adoption but as far as I can fathom my work (~3 years) will become obsolete very soon. Since corefx was announced I've started working on a library which can do basic stuff like encode/decode pngs, bmps, jpegs, and gifs (animated too), I've partially implemented some primitives for shapes and colors, and am experimenting with resampling algorithms now. All that work can be found [here](https://github.com/JimBobSquarePants/ImageSharp) I'm super uneasy about doing all this work though as I don't want it to be in vain, superseded immediately by something out of Microsoft. Should I continue? If so is it something that you would think the community could invest in and help me deliver (Graphics is tricky stuff and I'm no computer scientist). 3779 area-System.Runtime Collectible AssemblyLoadContext Collectible assemblies can be used for many different things but it usually comes down to some form of hot swapping code. Updating a plugin or compiling a new version of a Razor view, without restarting the process or leaking memory. .NET Core currently has no way to unload assemblies from memory if they are no longer required. In the full .NET Framework you could load the assemblies into a separate AppDomain so they can be unloaded later. ## Proposed API `AssemblyLoadContext` can be extended to enable developers to load normal assemblies, from the filesystem or any stream, as collectible assemblies. ``` csharp public abstract class AssemblyLoadContext { // ... protected AssemblyLoadContext(bool isCollectible) { } // ... } ``` Collectible assemblies loaded by `AssemblyLoadContext` would have the same [lifetime and limitations as those generated by `System.Reflection.Emit`](https://msdn.microsoft.com/en-us/library/vstudio/dd554932%28v=vs.100%29.aspx), except the lifetime extends to all assemblies loaded by the `AssemblyLoadContext`. This means the `AssemblyLoadContext` will not unload until there are no references to any of the assemblies it loaded. I am working on the implementation for this in CoreCLR: https://github.com/dotnet/coreclr/pull/1684 3780 area-System.IO IOException on recursive Directory.Delete of path with trailing backslash I observed this after we took a recent beta System.IO over in MSBuild. Many of our tests create a directory and have a `finally` that deletes it, which suddenly started failing. After debugging, I think this is a regression caused by 0721434, which added a call in [`RemoveDirectory`](https://github.com/dotnet/corefx/blob/0721434e19e7f9ecf8bf6dba7485f6c86827388c/src/System.IO.FileSystem/src/System/IO/Win32FileSystem.cs#L491) to canonicalize the path to extended form. The following call then adds a backslash before calling `FindFirstFile`, but the extended path has different behavior in Win32: it no longer silently condenses double backslashes to a single path separator. While proving to myself that I understood the bug I wrote a fix; I'll send a PR shortly. 3783 area-System.Net Disable failing ConnectV4MappedIPEndPointToV4Host_Success test #3744 cc: @pgavlin, @davidsh, @CIPop 3784 area-Infrastructure ALINK : error AL1078: Error signing assembly -- Access is denied.

When I restore packages of my dnx app I frequently (~50% of the time) get a segfault if the request fails with an HTTP error (e.g. 404 or 400). I am not exactly sure if this is a bug in coreclr, libcurl or somewhere else. I was not able to repro this issue on Linux. I also don’t seem to be getting the segfault if the request succeeds.

All of the other methods which modify / enumerate `s_EventSources` take care to lock the appropriate guard. This method is the sole exception.

The read method in FakeNetworkStream does do NetworkRead on some condition which itself is wrong. As a result, in successive read, data is never read from the network. So for now we have put a workaround method named DoNetworkRead(), which is being explicitly called from SslStream_StreamToStream_Successive_ClientWrite_Success. This issue is to remove DoNetworkRead() & find the real fix so that a NetworkStream encapsulation is maintained 3806 area-System.Net PreAuthenticate fix When CURLOPT_HTTPAUTH is set to any, libcurl will first query the server to figure out the right authentication scheme. This breaks the expectation when PreAuthenticate is set to true. We need to iterate over available schemes and set the auth-scheme flags to only those that are available. Also, while updating the CredentialCache, we ignore ArgumentException (raised when the cache contains the given url and scheme pair) 3807 area-System.Net Adding client cert validation logic and usage of EncryptionPolicy This includes: 1. Client Certificate validation logic at server side. Enabled the Verify_callback. Added the logic of updating CA list to be sent to client. 2. Added the usage of EncryptionPolicy flag passed during handshake. 3. Enabled the constructors of SafeX509Handle and X509StoeCTXHandle to generate the handle from an Intptr. 4. Added SafeX509NameStackHandle to be used by the stack related APIs. 5. Added a few X509_NAME stack related Macro-functions in *X509_name.cpp/.h Testing done locally using the existing security testcases for Encryption Policy variations. Client Cert validation logic is tested by directly calling AuthenticateAsServer method by enabling clientCertificateRequired flag. 3808 area-System.Net Disable another failing sockets test #3494 cc: @pgavlin, @davidsh 3809 area-System.Net Fix bugs in IPPacketInformation. - GetHashCode() and Equals() both stood the chance of dereferencing a null pointer when called on default values. - GetHashCode() was using a weak method of combining hash codes.

Note that this does work in the .NET Framework when emitting to a MethodBuilder that's not backed by a DynamicMethod. We could either get the support for it in CoreCLR or consider an emulation strategy a la a try/catch/rethrow/finally with a Boolean flag to check whether an exception was observed. 3839 area-System.Security System.Security.Cryptography.Algorithms.dll appears multiple time in the reference assemblies When you build the reference assemblies, the assembly System.Security.Cryptography.Algorithms.dll appears 3 times: ./bin/ref/System.Security.Cryptography.Algorithms/4.0.0.0/System.Security.Cryptography.Algorithms.dll ./bin/ref/System.Security.Cryptography.Cng/4.0.0.0/System.Security.Cryptography.Algorithms.dll ./bin/ref/System.Security.Cryptography.X509Certificates/4.0.0.0/System.Security.Cryptography.Algorithms.dll when I think it should only appear in ./bin/ref/System.Security.Cryptography.Algorithms/4.0.0.0/System.Security.Cryptography.Algorithms.dll 3840 area-System.Linq Expression interpreter - No support for TryFault This is not implemented right now. It may be possible to get it to work if we could get a try...fault... region in the interpreter code (in particular in EnterTryCatchFinallyInstruction.Run) but the C# compiler does not have this construct. Some options are: - Get it into the compiled binary using some ILASM magic, possibly by using a helper TryFault method that's self-contained and is parameterized on interpreter instruction ranges (range of try, range of fault, etc.). May be tricky with build. - Piggyback on a C# language construct that emits fault blocks, e.g. using blocks in iterators. An example of this trick is pasted below, but it'd obviously be changed to be parameterized on instruction ranges rather than take in Action delegates. - Emulate try...fault in some lowering phase by rewriting it to try...finally with a Boolean flag check. This could also be the way to get TryFault to work on the compiler, see #3838. Will have to be double-checked to be conform the exception semantics of the CLR construct. ``` csharp static class ExceptionHelpers { public static void TryFault(Action body, Action fault) { TryFaultCore(body, fault).MoveNext(); } private static IEnumerator TryFaultCore(Action body, Action fault) { using (new Handler(fault)) { body(); yield return null; } } } struct Handler : IDisposable { private readonly Action _fault; public Handler(Action fault) { _fault = fault; } public void Dispose() { _fault(); } } ``` 3841 area-System.Linq Expression interpreter - No support for exception filters "The expression interpreter lacks support for TryCatch with a CatchBlock whose Filter property is non-null. This is properly supported in the expression compiler though. Support for this could be likely be added by unflattening the list of catch blocks that are processed by EnterTryCatchFinallyInstruction.Run and using C# 6.0's support for filters to run a region of interpreter instructions when an exception occurs (those would have an ""isinst"" check followed by the user-supplied filter code) which get skipped on regular code paths using a goto. The reason the list of catch blocks needs to be unflattened (just in this case, we can keep things compact in cases where no filters are used) is to ensure that the code in the filters runs prior to unwinding the stack, such that any side-effects are visible across filters and eventually when the handlers run. By piggybacking on the CLR support for filters, we don't have to worry about this stack walk to evaluate which handler to use by running filter expressions; we just have to keep the nesting of exception handlers consistent with the emitted expression. Rough idea: ``` csharp public override int Run(InterpretedFrame frame) { // ... try { // ... } catch (Exception ex) when (RunFilter(frame, _filter.StartIndex, _filter.EndIndex)) { // ... } // ... } ``` There may be some trickiness around keeping the stack balance in all cases, but should be doable.

While the intent of using async WinHTTP calls is better performance and cancel-ability, this PR has not been fully optimized yet.

Our company focused on multi-agent solutions that are installed into multi-node trusted environment. So for recent years we use HttpListener and develop some set of lightweight http-servers, tightly bound to our task. If we need some features as Internet access, SSL, advaced static file support we use NGINX as frontend. So we not require to use some of prepared ASP.NET Servers or IIS while they are not so close to our task. But HttpListener has http.sys implementation in .NET so we require use netsh in Windows, if we use Mono - on Windows we got troubles and bugs and on Linux - all works well. So from netcore(dnx)/corefx we expected that HttpListener class will be kept but rewritten on Mono-like style with own socket wrapping and managed HTTP protocol support. So it would be good base for lightweight HTTP-based solutions. Instead of this we see that (or it seems) that roadmap of netcore is focused on aspnet-related HOSTS and we lost valid HttpListener support, but we are turned to use ASP.NET+MS MVC or Kestrels model. It's not what we expected - all other modules (as Reflection, Xml and so on) moved to more atomic and know-what-you-exactly-want style and design. But in NET stack we still see tendention to using monstrous-like complex ""hosts"". In System.Net.Http we see some improvements for client HTTP but not for Server. May we are not right but we not see activity on HttpListener or it's analog so it's limitation that force as to keep using not unified .NET 4.5 + Mono 4.0.4 stack.

Without this documentation you either have to catch everything ([well-documented as a bad practice](https://msdn.microsoft.com/en-us/library/ms182137.aspx?f=255&MSPPError=-2147217396)) or make educated guesses based on experimentation and [digging](https://stackoverflow.com/questions/24689263/exception-handling-for-httpclient-getstringasyncurl-async-api-call) through [various](https://social.msdn.microsoft.com/Forums/en-US/d8d87789-0ac9-4294-84a0-91c9fa27e353/bug-in-httpclientgetasync-should-throw-webexception-not-taskcanceledexception?forum=netfxnetcom) posts online, and if you go that route it's easy to miss that it throws, e.g., InvalidOperationException if the charset of the content type of the requested page can't be parsed into an encoding. 3895 area-System.Net Revising System.Net.Sockets contract v4.1 This issue discusses the changes being proposed in the current API surface of `System.Net.Sockets` contract version 4.1 in .NET Core. Version 4.1 is currently at an experimental stage and this revision takes it closer to the shape we intend to release at ASP.NET 5 RTM. ## Rationale .NET Core as a platform is intended to be modern, performant and cross-plat, so we need to ensure that the API surface is streamlined and adapted accordingly. This revision omits some of the Windows-specific or legacy types and methods that were present in the earlier (beta8) version of 4.1, and now includes new methods that follow the recommended TPL (async/await) pattern. ## Proposed API and Usage Following are the new Task Parallel Library-compatible methods being added to the class `System.Net.Sockets.Socket`. These are being added as extension methods to `Socket` class so that they can be supported on .NET framework via an OOB package as well (since we cannot add instance methods to types that are already defined in the .NET framework) ``` c# public static partial class SocketTaskExtensions { public static System.Threading.Tasks.Task AcceptAsync(this System.Net.Sockets.Socket socket) public static System.Threading.Tasks.Task AcceptAsync(this System.Net.Sockets.Socket thisSocket, System.Net.Sockets.Socket acceptSocket) public static System.Threading.Tasks.Task ConnectAsync(this System.Net.Sockets.Socket socket, System.Net.EndPoint remoteEndPoint) public static System.Threading.Tasks.Task ConnectAsync(this System.Net.Sockets.Socket socket, System.Net.IPAddress address, int port) public static System.Threading.Tasks.Task ConnectAsync(this System.Net.Sockets.Socket socket, System.Net.IPAddress[] addresses, int port) public static System.Threading.Tasks.Task ConnectAsync(this System.Net.Sockets.Socket socket, string host, int port) public static System.Threading.Tasks.Task ReceiveAsync(this System.Net.Sockets.Socket socket, System.ArraySegment buffer, System.Net.Sockets.SocketFlags socketFlags) public static System.Threading.Tasks.Task ReceiveAsync(this System.Net.Sockets.Socket socket, System.Collections.Generic.IList> buffers, System.Net.Sockets.SocketFlags socketFlags) public static System.Threading.Tasks.Task ReceiveFromAsync(this System.Net.Sockets.Socket socket, System.ArraySegment buffer, System.Net.Sockets.SocketFlags socketFlags, System.Net.EndPoint remoteEndPoint) public static System.Threading.Tasks.Task ReceiveMessageFromAsync(this System.Net.Sockets.Socket socket, System.ArraySegment buffer, System.Net.Sockets.SocketFlags socketFlags, System.Net.EndPoint remoteEndPoint) public static System.Threading.Tasks.Task SendAsync(this System.Net.Sockets.Socket socket, System.ArraySegment buffer, System.Net.Sockets.SocketFlags socketFlags) public static System.Threading.Tasks.Task SendAsync(this System.Net.Sockets.Socket socket, System.Collections.Generic.IList> buffers, System.Net.Sockets.SocketFlags socketFlags) public static System.Threading.Tasks.Task SendToAsync(this System.Net.Sockets.Socket socket, System.ArraySegment buffer, System.Net.Sockets.SocketFlags socketFlags, System.Net.EndPoint remoteEndpoint) } public struct SocketReceiveFromResult { public int ReceivedBytes; public EndPoint RemoteEndPoint; } public struct SocketReceiveMessageFromResult { public int ReceivedBytes; public SocketFlags SocketFlags; public EndPoint RemoteEndPoint; public IPPacketInformation PacketInformation; } ``` The usage of these new methods is the same as other APIs in .NET that follow the async/await pattern. For example: ``` c# private async void ConnectToServerAsync () { var socket = new Socket(SocketType.Stream, ProtocolType.Tcp); await socket.ConnectAsync(serverAddress, serverPort); // Use connected socket. } ``` ## Pull Request The pull request for this API change is #3655. It shows the diff from the previous revision of this contract, so you can see the types and methods that are no longer included in the proposed revision. ## Updates from Discussion - Revised initial proposal based on API review feedback from @terrajobst - Revised the signatures of methods `ReceiveFromAsync` and `ReceiveMessageFromAsync` based on feedback from @CIPop and @stephentoub - these async methods were modifying multiple variables through `ref` and `out` parameters. In order to avoid this, we have now defined their return values as structs (`SocketReceiveFromResult` and `SocketReceiveMessageFromResult`) that contain all the variables returned by the respective async methods. These new structs will also be added to the contract. - Also revised `ReceiveAsync` and `SendAsync` methods to accept `ArraySegment` as input parameter, in order to match existing APIs. - Need to add overloads for methods such as ConnectAsync, SendAsync and ReceiveAsync that take CancellationTokens to support canceling the operations 3905 area-System.Net Disable failing socket tests running in elevated mode Some of the cases expected to fail don't actually fail when running elevated. See https://github.com/dotnet/corefx/issues/3726. This disables those test cases so the tests can run in elevated mode. 3906 area-System.Diagnostics PerformanceCounters - Read OS counters on .NET Core Currently CoreFX generates the reference assembly System.Diagnostics.PerformanceCounter.dll however, there doesn't seem to be any counter part implementation for it, nor can I see an entry for this in the progress page at https://github.com/dotnet/corefx-progress/blob/master/src-diff/README.md. Is this expected? Thanks 3908 area-System.Linq Incorrect exception in parameterised block's last child is null. Creating a block from a list of expressions which contains a null normally throws `ArgumentNullException`. However, if this null expression is the last expression, and if the block has variables and doesn't have an explicitly set type, then it throws `NullReferenceException` instead. 3909 area-System.Linq Wrong parameter name when creating block with erroneous element Creating a `BlockExpression` with a null or unreadable expression throws `ArgumentNullException` and `ArgumentException` respectively. However, if the call was made to one of the overloads that receives these expressions as `IEnumerable` or `params Expression[]` and there is no explicit type, no variables and the number of expressions is between 2 and 5, then the parameter name in the exception throw is incorrect. 3911 area-System.Net Finish most of the sockets shims. - Shim SocketFlags - Shim select() - Fix some issues with error propagation in socket creation and accepted sockets The only functions that have not been shimmed are those relied upon for event notification (epoll/kqueue). 3913 area-System.Net System.Net.Sockets 4.1. contract contains several Windows-specific APIs and APM pattern methods This issue tracks the removal of some APIs from the Sockets contract in order to align it better to the .NET Core platform. ## Rationale The current version of Sockets 4.1 contract in beta8 includes some types, properties and methods that are tied to Windows-specific concepts. Since .NET Core is intended to be cross-plat, these need to be excluded in order to provide similar behavior and API surface across platforms. Further, the Sockets contract also contains methods following the APM pattern (Begin/End), which is not supported for other APIs within .NET Core. Hence, these methods are being excluded and new methods are being added that follow the recommended pattern TPL-based pattern of async/await (See #3895). Lastly, there are some constructors that are performing expensive, blocking operations within the constructor - these need to be removed as well. This issue tracks the removal of these APIs - a related issue is #3895 , which tracks addition of the TPL-based methods. ## Proposed API Exclusions Following are the types, properties and methods being excluded by the proposed revision to the contract: ### Types: ``` c# public partial struct SocketInformation public enum SocketInformationOptions public enum TransmitFileOptions ``` ### Properties/Methods/Constructors: ``` c# Type: Socket public Socket(System.Net.Sockets.SocketInformation socketInformation) public System.IAsyncResult BeginAccept - all overloads public System.IAsyncResult BeginConnect - all overloads public System.IAsyncResult BeginDisconnect public System.IAsyncResult BeginReceive - all overloads public System.IAsyncResult BeginReceiveFrom public System.IAsyncResult BeginReceiveMessageFrom public System.IAsyncResult BeginSend - all overloads public System.IAsyncResult BeginSendTo public void Disconnect(bool reuseSocket) public bool DisconnectAsync(System.Net.Sockets.SocketAsyncEventArgs e) public System.Net.Sockets.SocketInformation DuplicateAndClose(int targetProcessId) public System.Net.Sockets.Socket EndAccept - all overloads public void EndConnect(System.IAsyncResult asyncResult) public void EndDisconnect(System.IAsyncResult asyncResult) public int EndReceive - all overloads public int EndReceiveFrom(System.IAsyncResult asyncResult, ref System.Net.EndPoint endPoint) public int EndReceiveMessageFrom(System.IAsyncResult asyncResult, ref System.Net.Sockets.SocketFlags socketFlags, ref System.Net.EndPoint endPoint, out System.Net.Sockets.IPPacketInformation ipPacketInformation) public int EndSend - all overloads public int EndSendTo(System.IAsyncResult asyncResult) public void SetIPProtectionLevel(System.Net.Sockets.IPProtectionLevel level) Type: SocketAsyncEventArgs public bool DisconnectReuseSocket public System.Net.Sockets.TransmitFileOptions SendPacketsFlags Type: SocketFlags MaxIOVectorLength Type: TcpClient public TcpClient(System.Net.IPEndPoint localEP) public TcpClient(string hostname, int port) public System.IAsyncResult BeginConnect - all overloads public void Connect - all overloads public void EndConnect(System.IAsyncResult asyncResult) Type:TcpListener public System.Net.Sockets.Socket AcceptSocket() public System.Net.Sockets.TcpClient AcceptTcpClient() public void AllowNatTraversal(bool allowed) { } public System.IAsyncResult BeginAcceptSocket(System.AsyncCallback callback, object state) public System.IAsyncResult BeginAcceptTcpClient(System.AsyncCallback callback, object state) public static System.Net.Sockets.TcpListener Create(int port) public System.Net.Sockets.Socket EndAcceptSocket(System.IAsyncResult asyncResult) public System.Net.Sockets.TcpClient EndAcceptTcpClient(System.IAsyncResult asyncResult) Type:UdpClient public UdpClient(string hostname, int port) public void AllowNatTraversal(bool allowed) public System.IAsyncResult BeginReceive(System.AsyncCallback requestCallback, object state) public System.IAsyncResult BeginSend - all overloads public void Connect - all overloads public byte[] EndReceive(System.IAsyncResult asyncResult, ref System.Net.IPEndPoint remoteEP) public int EndSend(System.IAsyncResult asyncResult) public byte[] Receive(ref System.Net.IPEndPoint remoteEP) public int Send - all overloads public Task SendAsync(byte[] datagram, int bytes) ``` ## Pull Request The pull request that implements the removal of the above APIs is #3655 ## Discussion We are looking for feedback on the removal of these APIs based on the rationale described above. Also, if your code uses any of these APIs, please look at the revised contract in the PR for alternatives to use instead. If you believe the alternatives are not sufficient to address specific scenarios, that would be good to raise here as well. 3915 area-System.Net ClientAsyncAuthenticate_EachProtocol_Success failed in CI on Windows http://dotnet-ci.cloudapp.net/job/dotnet_corefx_windows_release_prtest/5187/console ``` System.Net.Security.Tests.ClientAsyncAuthenticateTest.ClientAsyncAuthenticate_EachProtocol_Success [FAIL] Timed Out Expected: True Actual: False Stack Trace: d:\j\workspace\dotnet_corefx_windows_release_prtest\src\System.Net.Security\tests\FunctionalTests\ClientAsyncAuthenticateTest.cs(196,0): at System.Net.Security.Tests.ClientAsyncAuthenticateTest.ClientAsyncSslHelper(EncryptionPolicy encryptionPolicy, SslProtocols clientSslProtocols, SslProtocols serverSslProtocols) d:\j\workspace\dotnet_corefx_windows_release_prtest\src\System.Net.Security\tests\FunctionalTests\ClientAsyncAuthenticateTest.cs(90,0): at System.Net.Security.Tests.ClientAsyncAuthenticateTest.ClientAsyncAuthenticate_EachProtocol_Success() ``` 3918 area-System.Net Create a placeholder stub for WebSockets.Client for non-Windows platforms WCF currently depends on WebSockets.Client API, but this API is not exposed on non-Windows platforms.

It would appear that the libraries we link against are still present in El Captian (so the .dylib we build should still run there) we just can't seem to build it out of the box. We need to figure out what the correct work around is (does installing the previous version of XCode or the command line compiler tools work, or maybe we need to get the headers via homebrew or something else)? The fact that Apple is on a 0.9.8 version of OpenSSL seems like it will also hurt us in obtaining the correct headers from a reasonably up to date package manager. 3926 area-System.Net Merge changes from TFS 3930 area-Meta Windows 7 build fails (update dev instructions about proxies and myget.org access) "I've been trying to build the latest good build for a couple of hours, I've updated dnvm and dnu build still cannot build: EXEC : error : FindPackagesById: Microsoft.NETCore.Platforms [c:\git\dotnet\corefx\build.proj] An error occurred while sending the request.

While that should be addressed separately to use WriteAsync, it's possible others are also using Write instead of WriteAsync, and today we throw NotSupportedException from Write. So as to let this at least work, I'm implementing Write to delegate to WriteAsync. I also noticed we were missing a FlushAsync implementation, so I've added one. cc: @davidsh, @roncain, @kapilash 3986 area-System.IO Use Optimized Zlib-Intel to Build clrcompression.dll **Summary** Intel has developed an optimized version of Zlib that includes architecture specific optimizations and algorithmic changes to improve the included deflate() and crc32() functions. Since System.IO.Compression calls out to these functions through clrcompression.dll, I suggest that Zlib-Intel to be used to build clrcompression.dll. **Test Results** I have compiled the library myself, and by renaming the .dll to clrcompression.dll and replacing the clrcompression included with .NET Core, I see an improvement of **20-30%** when doing compression using GZipStream on an Intel® 5th Generation Core (tm) i5 Processor based system, as well as on an Intel® Xeon® Processor E5 v2 Family based server system. The gain comes entirely from the optimized deflate() function. **Link** The developer of Zlib-Intel has provided support for VS Intrinsics here: https://github.com/jtkukunas/zlib/tree/win32_nmake 3993 area-System.IO "Overload of Directory.DeleteDirectory(""path"", true) that deletes what it can and leaves rest" Whenever we have clean up code to remove directories and files, we always end up with hacks to workaround issues with readonly files, handles being temporarily held.

The design of the WinHttpRequestState is such that it stays alive due to a GCHandle.Alloc(this) in its constructor. This keeps the object alive during any of the native WinHTTP callbacks. However, the object was being prematurely disposed during the Dispose() of the WinHttpResponseStream. Instead, it should have been explicitly disposed during the final HANDLE_CLOSING callback from WinHTTP when the request handle was disposed. The early disposing of the WinHttpRequestState object was doing a GCHandle.Free() of the state object. This later caused an Assert() in the DEBUG version of the CoreCLR when doing GCHandle.FromIntPtr() indicating that the handle was already deallocated. 4002 area-System.Net "Sockets tests depend on ""localhost"" resolving to an IPv6 and an IPv4 address" This is not always the case on Linux: how the name resolves depends on the host's configuration. 4003 area-System.Net Socket_SendToAsyncV4IPEndPointToV4Host_Throws_Unix fails on OSX. 4004 area-System.Net OS X does not provide IPv4 packet info for dual-stack sockets.

" 4031 area-System.Net Fix System.Net's Interop.OpenSsl error handling There are 2 issues with OpenSsl's current error handling 1. In Interop.OpenSsl.Disconnect, we are ignoring the SSL_get_error error code, and just continuing even though there was an error from SSL_shutdown. 2. There are 2 sets of error codes in OpenSSL: 1. Those defined in err.h 2. Those defined in ssl.h These two sets overlap, for example ERR_R_SYS_LIB = 2 and SSL_ERROR_WANT_READ = 2. In Interop.OpenSsl.GetSslError, if the SslErrorCode returned from SSL_get_error (defined in ssl.h) is SSL_ERROR_SYSCALL, it calls ERR_get_error (defined in err.h), and casts that result to an SslErrorCode, which is incorrect since it will return a separate set of error codes.

I've rebased my work from my dev branch (dev/ni-xplat) into a single commit, as the history of that branch was very very convoluted and messy, and wasn't easily rebaseable. On top of that, I've run CodeFormatter.exe, manually formatted the project file with some extra spacing, and resolved an additional merge conflict with the master branch. The code was reviewed prior to merging into the dev branch. For context for anyone wanting a brief overview, here's the description I put into the consolidated commit: This commit adds the Linux and OSX implementations for System.Net.NetworkInformation, a library for querying local system information regarding network interfaces, network capabilities, current network connection status, socket connections, various network protocol statistics, both global and per-network-interface, current network addresses, and various other configuration options and statistics. On Linux the information is primarily surfaced through: - /proc/net/*, various other in-memory files that expose network configuration and machine statistics - Getifaddrs() for querying the addresses for all network interfaces - Netlink sockets for detecting network address change events On OSX: - Sysctl: Exposes most of the network and protocol statistics, as well as routing information, configuration options, etc. - Getifaddrs(): Same as above, for enumerating addresses. - Some network configuration files are also parsed from disk, if available, similar to above. NOTE: Due to the fact that this API is closely tied to the information and statistics that are exposed through Win32 APIs (iphlpapi.dll), some individual pieces of information are not available on Linux and OSX. Depending on the range of information exposed through those operating systems, we are able to gather much of the same data, but it is often not identical to the set that is exposed from Windows. Members that cannot be retrieved instead throw a PlatformNotSupportedException. 4040 area-System.IO DriveInfo tests seeing / instead of \ after CoreCLR test-runtime upgrade ``` Discovered: System.IO.FileSystem.DriveInfo.Tests Starting: System.IO.FileSystem.DriveInfo.Tests System.IO.FileSystem.DriveInfoTests.DriveInfoWindowsTests.TestConstructor [FAIL] Assert.Equal() Failure Expected: C:\ Actual: C:/ Stack Trace: D:\Src\corefx\src\System.IO.FileSystem.DriveInfo\tests\DriveInfo.Windows.Tests.cs(39,0): at System.IO.FileSystem.DriveInfoTests.DriveInfoWindowsTests.TestConstructor() Finished: System.IO.FileSystem.DriveInfo.Tests === TEST EXECUTION SUMMARY === System.IO.FileSystem.DriveInfo.Tests Total: 8, Errors: 0, Failed: 1, Skipped: 0, Time: 0.313s ``` 4041 area-System.Net Unify the two definitions of WinHttpException.

Further, an equivalent method that follows the TPL pattern already exists in this class and should be the one that is used for this functionality: ``` c# public virtual System.Threading.Tasks.Task GetUnicastAddressesAsync() ``` 4045 area-System.Reflection Handle properties on types in System.Reflection.Metadata should be public "It appears that all types that wrap metadata rows (such as TypeDefinition) have a private Handle property. [Example](https://github.com/dotnet/corefx/blob/master/src/System.Reflection.Metadata/src/System/Reflection/Metadata/TypeDefinition.cs#L36-L39): ``` csharp // from TypeDefinition.cs private TypeDefinitionHandle Handle { get { return TypeDefinitionHandle.FromRowId(RowId); } } ``` I find that I often use LINQ to search thru table results looking for specific information, but need the handle at the end. For example, this code searches thru the TypeReferences for System.Object - useful for finding all the class objects in an assembly. Note how I have to create an anonymous type to hold the handle separately from the type reference, even though the TypeReference can easily construct a handle internally. ``` csharp _reader.TypeReferences .Select(h => new { Handle = h, TypeRef = _reader.GetTypeReference(h) }) .Where(o => _reader.GetString(o.TypeRef.Name) == ""Object"" && _reader.GetString(o.TypeRef.Namespace) == ""System"") .Select(o => o.Handle) .Single(); ``` I'd much rather write this: ``` csharp _reader.TypeReferences .Select(h => _reader.GetTypeReference(h)) .Where(tr => _reader.GetString(tr.Name) == ""Object"" && _reader.GetString(tr.Namespace) == ""System"") .Select(tr => tr.Handle) .Single(); ``` " 4046 area-Meta Co-locate Reference Docs and Sample Code within the Repo on a Per-Library Basis "# Problem As .NET Core moves the platform towards being more modular, sample code and reference docs should move in that direction too. We should have a good story in place for reference docs and samples. **Note:** Samples here mean samples which _only_ call the API they are co-located with. These are not cross-cutting, they don't cover scenarios, and they don't involve other app models (ASP.NET, UWP, etc). They will be console apps which cover only the ""happy path"" of an API in a demonstrative way. # Solution Co-locate reference docs and samples with the code they describe and demonstrate usage of, on a per-library basis. The existing structure of libraries in corefx would be altered as such (using `System.Linq` as an example): Before: ``` /src |__System.Linq |__/ref |__/src |__/tests ``` After: ``` /src |__System.Linq |__/ref |__/doc (new! contains documentation, perhaps in markdown files) |__/src |__/samples (new! contains a buildable sample project) |__/tests ``` Sample code in `/samples` will be embedded directly into docs in the `/doc` folder so that any time sample code is changed, the documentation is automatically updated. See [an example of how this may look](https://github.com/cartermp/corefx/tree/samples/src/System.Linq) for some more detail. ## Building The proposed solution would affect the build process. I see two options here: a. Force `/samples` to build before a release b. Eventually have `/samples` build as ""full"" build, but do not require that to release Both have their benefits and drawbacks which are worth discussing. Finally, hooks will have to eventually be added to force other sample projects outside of corefx to build so their sample code can also stay up-to-date. # Justification This solution will form the ""core"" of an eventual samples system which will ultimately accomplish the following: - Easier to update reference docs and samples if they live with the code they describe - No code samples in reference docs will be out-of-date and fail to compile - No code samples in any .NET Core conceptual docs will be out-of-date and fail to compile - No .NET Core sample applications will be out-of-date and fail to compile We want to avoid a future scenario where developers have to turn to places like StackOverflow to learn how to use an API because the sample code in the documentation is outdated and/or won't compile. If all our .NET Core samples are tied into the build system, we can avoid that scenario.

This can be added externally easily enough: ``` C# public static bool TryUpdate(this ConcurrentDictionary dict, TKey key, Func updateFactory) { TValue curValue; while(dict.TryGetValue(key, out curValue)) { TValue value = updateFactory(key, curValue); if( (default(TValue) == null && ReferenceEqual(curValue, value)) || dict.TryUpdate(key, value, curValue) ) return true; } return false; } ``` But this is slower (and hence more likely to have to loop) than if the call was an instance method, and also prevents the factory from being called with the stored key rather than the passed key (should a difference be significant to the factory). That it's come up for at least someone else before is suggested by http://stackoverflow.com/q/12240219/400547 (they didn't need the key in their factory, but the above would have provided them with an answer too as their factory could simply ignore it). 4074 area-System.Security If possible, stop hard-coding magic values that aren't exposed in OpenSSL headers See discussion here: https://github.com/dotnet/corefx/pull/4026/files#r42687456 4076 area-System.Collections [RC1 blocker] Access violation while running System.Collections.Tests in CI on Linux http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst_prtest/3747/consoleFull ``` 08:32:50 Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AccessViolationException: Attempted to read or write protected memory.

The blocking was coming from a task continuation resuming on the same thread and subsequently calling a blocking Stream.Write method in a custom HttpContent class being written onto the request stream. Blocking is not allowed on the WinHTTP callback thread. So any task continuations need to occur on a different thread. The fix is to create the TaskCompletionSources to use RunContinuationsAsynchronously. This allows them to unblock the WinHTTP thread. Additionally, I added some missing ConfigureAwait(false) settings to some await'd operations. Added a new test which uses a custom HttpContent class that uses a blocking Write() call when serializing onto the request stream. Fix #4077 4080 area-System.Net Fix WinHttpHandler on Win7 When WinHttpHandler was recently switched to use async WinHTTP pattern, it started setting an option which improves performance. However, the WINHTTP_OPTION_ASSURED_NON_BLOCKING_CALLBACKS option is not available on downlevel Windows versions. This was causing an exception to be thrown when sending an HTTP request. The fix is to ignore the ERROR_WINHTTP_INVALID_OPTION error code when trying to set this option. 4081 area-System.Net Removing Nuget.Props file Nuget.Props file was added by mistake in a previous commit. 4082 area-System.Net Enable NetworkInformation tests on Linux, OSX "cc: @stephentoub , @CIPop This removes the ""Unsupported"" tag for OSX and Linux from the NetworkInformation tests. Some of the tests just attempt to enumerate all of the properties and statistics that the library exposes. I've disabled those test cases on Linux and OSX because many of those members are not supported. I encountered a couple small issues after running the tests and fixed the issues in subsequent commits: - In Linux's NetworkChange implementation, the field storing the netlink socket's file descriptor was not being set to 0 after it was closed. This means if you tried to close the socket, and then re-open or re-close it, you'd hit a debug assertion I had in place. I've set the field to 0 after it is closed, and clarified the debug assertion messages. - UnixIP(v4/v6)InterfaceProperties was caching the network interface's index too early, and was always storing 0. The network interface's index isn't initialized until the link-layer address is enumerated from the native shim call. To avoid timing issues like this, I might consider storing all of the information from the address enumeration in a separate object, and then constructing the UnixNetworkInterface object all at once. - OSX didn't implement OperationalStatus. I've added a very crude implementation which just determines whether an interface is ""Up"" or not by checking if it has any addresses assigned to it. I think the OS exposes a bit more information here, but I don't think that we can necessarily map that info to our enum values (except perhaps ""Dormant"").

Some platforms behave strangely when confronted with linger times that are out-of-range. In particular, OS X silently truncates `linger::l_linger` to 16 bits and interprets the results as a `short`. This change validates the linger time before calling `setsockopt` to ensure reliable behavior across platforms. On OS X, the maximum linger time is actually in units of ticks, so validation is a bit more involved than on other platforms (where the max time is defined by the size of the integer used to store the value): on the first call to `SetLingerOption`, the number of ticks per second is obtained via `sysconf()` and is then used to derive the maximum linger time by simple division. This does mean that the maximum linger time on OS X may vary with the number of ticks per second, and so may vary between machines. 4087 area-System.Net Merge changes from TFS 4089 area-System.Net Provisionally Ignoring tests to unblock the build Some tests that are having different behavior following the System.Net.Sockets API revision will be disabled temporally. 4091 area-Meta Question: Is .Net Remoting supported?

This has been marked as _TODO_ in the source code. These _'other'_ accessors are not often encountered, but handling them is required for certain special case tooling. ## usage of _'other'_ property accessors * The .NET Framework exposes 'other' accessors through [PropertyInfo.GetAccessors](https://referencesource.microsoft.com/#mscorlib/system/reflection/propertyinfo.cs,496) * .NET assemblies generated by the 'tlbimp' tool can generate this metadata when a COM property has both a PUT and a PUTREF accessor. * They are valid metadata, even though rarely used, but if you build tools for processing or inspecting .NET assemblies (like tlbexp or ildasm do) you want to handle them. The last point is a real-world use case I have. The tlbexp functionality built into the .NET Framework requires loading an assembly into the AppDomain to generate a TLB. Loading the assembly can fail for various reasons, so generating a TLB by only inspecting metadata is desireable. The omission of 'other' accessors is a problem here. ## Proposed API ``` csharp namespace System.Reflection.Metadata { public struct PropertyAccessors { // Existing public MethodDefinitionHandle Getter { get; } public MethodDefinitionHandle Setter { get; } // New public ImmutableArray Others { get; } } public struct EventAccessors { // Existing public MethodDefinitionHandle Adder { get; } public MethodDefinitionHandle Remover { get; } public MethodDefinitionHandle Raiser { get; } // New public ImmutableArray Others { get; } } } ``` ## Details In the large majority of cases there will be no 'other' accessors in the metadata. It is trivially possible to implement this case without any additional allocations compared to the current implementation. For the purpose of the discussion I have provided an initial [implementation](https://github.com/weltkante/corefx/pull/3) of the suggested change. ## Updates - Expose other accessors directly on the `PropertyAccessors` and `EventAccessors` structs instead of returning them as an out-param 4101 area-System.Net Unix HttpClient does not use the same https server cert validation as Unix SslStream It seems that - If you start with a certificate that is not trusted by the OpenSSL default trust list - Then you add the root to the CurrentUser\My X509Store It still fails to validate on an https connection (but would succeed if connecting with SslStream). The two SSL consumers should use the same validation. 4104 area-System.Linq Re-evaluate various #define symbols in System.Linq.Expressions The following symbols are used in the code but are never set in corefx: - FEATURE_DLG_INVOKE - FEATURE_FAST_CREATE - FEATURE_MAKE_RUN_METHODS - FEATURE_THREAD_ABORT - FEATURE_STACK_TRACES - NO_FEATURE_STATIC_DELEGATE We should re-evaluate whether those are useful to enable in some build flavors e.g. to improve performance of the interpreter. 4108 area-Infrastructure Add validation that project.json's don't overspecify dependencies It would be really nice if we validated that no project.json specifies dependencies that aren't used.

On *nix, the OS IP stack changes a dual-mode socket back to a normal IPv6 socket once the socket is bound to an IPv6-specific address. This can cause behavioral differences in code that checks the value of DualMode (e.g. the checks in CanTryAddressFamily). We've decided not to emulate the Winsock behavior (which does not change the value of `IPV6_V6ONLY` for dual-mode sockets bound to IPv6-specific addresses) due to the cost of caching the expected value on each socket instance; some tests needed changes as a consequence of this decision.

On *nix, the SendTo APIs return ENETUNREACH instead of EFAULT when confronted with a socket address with an invalid address family: these platforms check the family of the provided socket address before checking its size (as long as the socket address is large enough to store an address family). Fixes #4003. 4117 area-System.Net WinHttpHandler: Fix POSTs with zero length content While researching #3292, I discovered that POST'ing zero length content throws an exception. This was because we were calling WinHttpWriteData() and passing in a zero length for the buffer size. This returns an error back from WinHTTP. We don't need to call WinHTTP APIs to write zero length data. We simply need to return a completed task back to the caller. Added tests to verify the fix. 4120 area-System.Net Unix HttpClient does not do CRL checking on the connection The libcurl+openssl default is to not check CRLs, since they have to be manually provided. The work done by #4101 isn't going to change the revocation check status, because currently the Unix X509Chain implementation doesn't support opportunistic revocation, and self-signed certs require opportunistic revocation. #2204 is the issue tracking opportunistic revocation. 4121 area-System.Net Make Unix HttpClient use X509Chain instead of the default chain validator "Opportunistically redirect the SSL validation logic. On OSX this is expected to return CURLE_NOT_BUILT_IN, and just use the DarwinSsl logic (unless the user has built libcurl+openssl themselves). This particular pull request enables the ability to use a self-signed certificate that is trusted only in the CurrentUser\Root store. Along the way I discovered that we weren't doing CRL validation either, and that's tracked in issue #4120. Enabling CRL validation in this change would mean self-signed test certs still don't work, because #2204 seems to be required for supporting ""opportunistic CRL"" (require it be valid if there's a CDP entry, but if there's no CDP don't consider that a failure). cc: @stephentoub @vijaykota @rajansingh10 @shrutigarg " 4123 area-System.Security Where's the TransformBlock functionality on SHA256?

The calls to MethodBase.Invoke in various places ultimately call into MethodBase.CheckArguments which performs a copy of the arguments array passed in. In cases such as the interpreter's where the caller is trusted to transfer ownership of the array, this copy is redundant. Both #4112 and this issue could possibly get resolved by controlling more of those behaviors (i.e. Type.Missing checks in #4112 and argument copying in this issue) through the Binder that's passed to the Invoke method. An (internal-only) specialized fast-path binder could be passed by the interpreter. 4128 area-System.Net Remove obsolete TODOs from xplat SslStream code In the code there are references to issue# 3362.

For HttpClient, because of lack of an explicit mechanism to indicate the error condition, we have been using HttpRequestException.InnerException.HResult as a consistent way to know what the error was. This was after a discussion with @davidsh and @CIPop about how to achieve this. For the error condition of the specified hostname in the url not resolving, we are expecting the HResult to have a value of 0x80072ee7 (ERROR_INTERNET_NAME_NOT_RESOLVED). With the Unix version of HttpClient, the value being returned is 0x00000006 (ERROR_INVALID_HANDLE). This is causing WCF to not be able to tell what the error condition is and we can't throw the correct exception. Currently we have one other error condition mapped, which is the case where the server sends a reset on the socket while we're receiving data. In this case, we expect an HResult of 0x80072eff (ERROR_INTERNET_CONNECTION_RESET). 4149 area-System.Linq [RC1 blocker] AV in System.Linq.Expressions tests http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst_prtest/3850/console ``` 15:34:41 Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AccessViolationException: Attempted to read or write protected memory.

System.Linq.Expression.Invoke not thread safe on lambda argument. "This is a crazy bug that took me awhile to track down. System.Expression.Invoke will modify its lambda argument, making it unsafe if the lambda can be changed in a field updated by another thread. This simple test illustrates the problem: ``` using System; using System.Diagnostics; using System.Linq.Expressions; using System.Threading.Tasks; public class Indirect { public Func DoItA = () => 0; public Func DoItB = () => 0; private int Count = 1; public void Refresh() { { var valueA = DoItA(); var valueB = DoItB(); Debug.Assert(valueA == valueB); } var idx = Count; Count += 1; DoItA = () => idx; DoItB = DoItA; } public static Action Compile(Indirect ind) { var ind0 = Expression.Constant(ind); var fld = Expression.PropertyOrField(ind0, ""DoItA""); var block = Expression.Block(typeof(void), Expression.Invoke(fld)); return (Action)Expression.Lambda(block).Compile(); } public static void DoTest() { var ind = new Indirect(); Task.Run(() => { while (true) ind.Refresh(); }); var act = Compile(ind); Task.Run(() => { while (true) act(); }); } } ``` Note that DoItA and DoItB are apparently only modified by the Refresh call that occurs in the first task forked by DoTest. However, the assertion will eventually fail because the mere invocation of the lambda through a field can cause that field to retain its value even if it is modified by another thread during the invocation! The work around on the user side is to load the field into a temporary variable and invoke on that variable. Not a big deal, but the fact that Expression.Invoke is not thread safe on its lambda argument is not documented...either it should be thread safe (by not storing into its lambda operand argument, which is really unexpected behavior), or it should be documented that it could do this.

We'll provide a functioning implementation later. Most of the Ping class can be shared between Windows and Unix. Since there's essentially just two instance methods (InternalSendAsync and InternalDisposeCore) that need differ between Windows and Unix, but which need access to the rest of the state on the Ping instance, I've made Ping a partial class and put those two methods into .Windows.cs and .Unix.cs files. The logic in the Windows implementation is unchanged, other than removing some dead code and cleaning up a few formatting issues. Some of the helper types, e.g. PingReply, had ctors with Windows-specific logic, so I moved those out of the helpers into Ping as platform-specific factories, leaving the helper types to be platform-agnostic. I've put the PR up with the commits that I had as I was going through the changes, but I'll squash them all (along with addressing any feedback) prior to merging. cc: @cipop, @pgavlin, @mellinoe 4161 area-System.Linq Expression compiler - VerificationException: Operation could destabilize the runtime.

I realize unequal objects can have the same hash code by accident, but I think it is not very useful if unequal objects _always_ have the same hash code, if only for debugging purposes. In normal Windows, a work around is probably to use the hashcode of Method (e.g. f.Method.GetHashCode()), which seems to return a more diverse result. However, in universal Windows, that member isn't available. We could also use the string, but that isn't useful when the lambda is compiled via the DLR.

In the new usages, I don't need to know about the link-layer addresses, so I don't pass a callback for them. - I pulled out two common methods into an IPAddressUtil class for use when dealing with Interop.SysEnumerateInterfaceAddresses. - The implemention for GetUnicastAddresses(Async) is the same for Linux and OSX, so I've created a ""UnixIPGlobalProperties"" base class that implements that method for both operating systems. - There was an additional marker regarding using sysctl to query the machine's address count. Looking at it again, I don't think it's actually worth bothering. All we are doing instead is adding up the number of addresses from the list of interfaces we already have.

Both the Windows and x-plat libraries use this type to return IPAddress collections. The base class (IPAddressCollection) throws a NotImplemented exception for the GetEnumerator method, which is not overridden here in System.Net.NetworkInformation. The Windows tests are not catching this issue because they are running against the ""System.Private.Networking"" version of System.Net.Primitives, which DOES implement the enumerator.

This addresses the last two issues I have tracked in #4060. - When calling into System.Native for obtaining TCP and UDP socket connection information (current open/listening sockets), just bail if the first call fails, i.e. if the estimated buffer size is not big enough. This is what most code examples do that I have seen, and I have not personally seen the first call fail anyways. - Shim out MapTcpState for Linux. There was previously a function doing the same thing, but only for OSX, and only in the context of gather connection informations. I've pulled it out into a separate source file and made an implementation for both platforms. This replaces the hard-coded enum in the managed code.

I liked it a lot, but there are some details where I would love some clarification in the document - It is about the Platform Standard. Nevertheless, many will use the netstandard TFMs for their libraries. So when speaking of ""Reference Assembly"" and ""Implementation Assembly"", I think we need a very clear separation between a library targeting a netstandard which is - distributed by an normal library developer which is portable (he delivers a nuget package with a ref and a implementation assembly (or only a impl?)) - distributed by an normal library developer which is not portable (bait and switch) - a library like System.IO which is 99% delivered as part of the platform which is not portable (which has a ref assembly and a implementation assembly per platform, in the platform), but nevertheless has a NuGet package. How does that work (only ref?). - a library like System.Xml.XDocument which is part of the CoreFx, which is portable which future platforms should just use via NuGet but some older platforms may still have as a implementation assembly in the platform. - I would add a line stating that targeting a lower platform standard is preferable. - In the CoreFx list a classification which library is portable, sometimes portable and always platform specific would be nice - A word about how the NuGet packages of the netstandard (e.g. System.IO) build only with their refs and their implementation assemblies as part of the platforms (they are build and shipped with them, e.g. in coreclr). I think it should be clarified that the public NuGet which reflect platform features only have refs. @davidfowl @AArnott ps: I am surely not 100% accurate here.

Today each test decides which dependencies are live (via ProjectReferences) or baseline (via packages). Additionally the baseline is only updated periodically. This can lead us to a place where folks commit bits that might work independently by not together. For TOF, internally, folks are solving this by always using a fixed set of packages after they are produced by the build.

It is not the same as truly passing arguments byref. Some methods, like ones from Interlocked family, rely on aliasing nature of ref and the difference is observable. Since all the calls in Interpreter are done via reflection, we cannot interpret certain calls correctly due to insufficient APIs. ============== Unlike the expression compiler where address-obtaining instructions are used to call by reference, the expression interpreter has to perform copy operations in and out of an arguments array upon calling the `Invoke` method. As a result, calls to constructs like `Interlocked` methods don't have the intended effect. An example repro is shown below: ``` csharp var inc = ReflectionUtils.MethodInfoOf((int x) => Interlocked.Increment(ref x)); var run = ReflectionUtils.MethodInfoOf(() => Task.Run(default(Action))); var all = ReflectionUtils.MethodInfoOf(() => Task.WaitAll(default(Task), default(Task))); var p = Expression.Parameter(typeof(int)); var n = Expression.Parameter(typeof(int)); var i = Expression.Parameter(typeof(int)); var b = Expression.Label(); var l = Expression.Block( new[] { i }, Expression.Loop( Expression.Block( Expression.IfThen( Expression.Equal(i, n), Expression.Break(b) ), Expression.Call(inc, p), Expression.PostIncrementAssign(i) ), b ) ); var a = Expression.Lambda(l); var t = Expression.Call(run, a); var e = Expression.Block( new[] { p }, Expression.Call(all, Expression.NewArrayInit(typeof(Task), t, t)), p ); var f = Expression.Lambda>(e, n).Compile(); ``` One would expect f(N) to return 2 \* N. This is the case for the compiler, but not for the interpreter. 4414 area-System.Net Cleanup System.Net.Http tests - Move more tests to the new test server - Cleanup 'var' coding patterns - Remove duplicate tests (*Content clas related) that are already covered with the *Content class tests - Utiilize the newer test server VerifyUpload endpoint which does 'Content-MD5' verification of transmitted payload to the server as well as payload from the server - Add GZip related tests in addition to Deflate compression schemes 4416 area-System.Net Cleanup System.Net.Http.WinHttpHandler tests - Move tests to the new test server - Fixup an SSL certificate test to handle wildcard certs - Remove HttpTestServers.cs file.

Tests: I modified the existing System.IO tests that used MemoryStreams to instead be inheritable. I made a FakeStream that is an indirection around MemoryStream that enables BufferedStream(new FakeStream) to be used interchangeably with MemoryStream(). Though wrapping a MemoryStream with a BufferedStream isn't useful in the real world, it's an adequate method of ensuring the BufferedStream is calling the underlying stream functions correctly. Coverage is 89%/80% for BufferedStream with these additions. resolves #1793 The tests will fail CI as they will be compiled against the contract pulled in from nuget for System.IO version 4.0.10. For testing, I manually modified the reference assemblies to those produced by my System.IO/src build and all tests pass.

The code is mostly modeled off of CoreCLR with some elements taken from build.sh building for native Unix components. It uses CMake to produce the projects that are then passed to msbuild. The logic primarily resides within the ""build-native.cmd"" script that is called by ""build.cmd"" from the corefx root when ""__BuildNative"" is set. Some things to be aware of: - __BuildNative in build.cmd is currently always set. Either some logic should be added to actually evaluate it, or the variable should be removed. - Cross compilation isn't set up. build-native.cmd can only build for windows at this time. It can build for x64 or x86, however. The default is currently x64. AnyCPU also defaults to x64. - Since manual parsing of args is used, most of the msbuild targets that can be passed to build.cmd will be ignored by native compilation. Currently, only Configuration and Platform are acknowledged. I can imagine a system where the native project can be used with the same targets as the managed ones, but that capability isn't complete now. Those properties/targets are still used in the managed build, of course. - A TFS-side commit to the package definitions will need to follow this PR so that we can consume the publicly built System.IO.Compression.Native. - I minimized most of the compilation options for Windows cmake.

My use case is getting a private constructor when there are multiple constructors: ``` type.GetConstructor( BindingFlags.Instance | BindingFlags.NonPublic, null, // binder new[] { typeof(object), ... }, null // modifiers ); ``` I assume these weren't exposed in corefx because you didn't want to provide the overloads with a `Binder` parameter, so something like these would be optimal however would be new overloads not available in .NET Framework: ``` public static MethodInfo GetMethod(this Type type, string name, BindingFlags bindingAttr, Type[] types) public static ConstructorInfo GetConstructor(this Type type, BindingFlags bindingAttr, Type[] types) ``` I've looked at using Linq over the `TypeInfo` but I'd have to check each property rather than use BindingFlags, and `TypeInfo` isn't available in .NET 3.5/4.0 so I can't just change to one or the other. For now I've emulated the old .NET Framework signature using `type.GetConstructors(bindingAttr).SingleOrDefault(...)`, it is ugly and likely heaps slower than the .NET Framework reflection call.

It was probably correct when we were hard-coding a version, but since we don’t know which version will actually be used, I think we should be letting the zlib library figure out which is the best compression level to use.

In order to implement certificate pinning and self-signed SSL certificate scenarios, developers need access to the SSL cert presented by the server, and the ability to do their own validation and then accept/reject the connection accordingly. Today, this ability is provided in .NET Framework by ServicePointManager.ServerCertificateValidationCallback and in ASP.NET 5 by WinHttpHandler.ServerCertificateValidationCallback. However, ServicePointManager is not in .NET Core, and WinHttpHandler is not available x-plat and on all app models.

Choosing `Automatic` lets the system choose the ""best"" client certificate for the user from among the installed and accessible ones. `Manual` means that the developer can explicitly pass in a client cert. However, `HttpClientHandler` does not have a `ClientCertificate` property, so you can't assign a certificate for the `Manual` option to use. This issue tracks the fix to address this gap. (`WinHttpHandler` has a `ClientCertificates` property for this purpose, but it is not x-plat and is not supported for all app models (e.g. UWP)) If you have specific requirements around this feature, please enter them here.

"This implements System.Net.Utilities on Unix. The implementation is shared between Unix platforms, and should work anywhere that either supports raw sockets or has a discoverable ""ping"" utility. There are two ""modes"" in which a Ping can be sent on Unix. If the user has privileges to create and use raw sockets, then the ""good"" path is taken. The good path uses raw sockets to send ICMP echo requests to the given host, and then listens for ICMP echo replies. If the user does not have privileges to do so, then the implementation simply launches a new process using the ping or ping6 utility program (depending on whether the destination address is an IPv4 or IPv6 address), parses the output, and returns the result. The information from the ""bad path"" is less reliable, and doesn't include things like the IPStatus property, which should be able to cover most of the possible ICMP response message types, not just ""Success"". Additionally, the ""bad path"" cannot send arbitrary buffers along with the echo request, although we can at least preserve the size of the data. This means you can't inspect the PingReply and see that the same data you sent in the echo request was returned unchanged. There are a couple of additions to the Sockets PAL and shim in order to accomodate the ICMP protocol which I'm using in the ""good path"" described above. @cipop, @stephentoub, @pgavlin " 4487 area-System.Data Mars - Intermittently Failed - because of race condition "Repro ``` using (var conn = new SqlConnection(""Data Source=***; User ID=***; Password=***;Initial Catalog=***;MultipleActiveResultSets=true;"")) { conn.Open(); var cmdText = ""select 1""; var cmd1 = new SqlCommand(cmdText, conn); var cmd2 = new SqlCommand(cmdText, conn); Console.WriteLine(""{0:hh:mm:ss} - Execute Reader 1"", DateTime.Now); using (var reader1 = cmd1.ExecuteReader()) { Console.WriteLine(""{0:hh:mm:ss} - Execute Reader 2"", DateTime.Now); using (var reader2 = cmd2.ExecuteReader()) { Console.WriteLine(""{0:hh:mm:ss} - Start Read Reader 2"", DateTime.Now); reader2.Read(); Console.WriteLine(""{0:hh:mm:ss} - Finish Read Reader 2"", DateTime.Now); } Console.WriteLine(""{0:hh:mm:ss} - Start Read Reader 1"", DateTime.Now); reader1.Read(); Console.WriteLine(""{0:hh:mm:ss} - Finish Read Reader 1"", DateTime.Now); } } ``` Sometimes this will error caused by syn packet was sent after the second data packet for second session sent.

I propose `EmitCall` which is the supported way to call varargs methods should have an overload to take `MethodBase` instead of a `MethodInfo`. see: http://stackoverflow.com/a/24041217/468672 edit: I propose adding the following method to the `IlGenerator` base type: ``` csharp public virtual void EmitCall(OpCode opcode, ConstructorInfo constructor, Type[] optionalParameterTypes); ``` This overload would allow support for calling a `vararg` constructor. Consider the following class `V` ``` csharp public class V { public int Count{get;} public V(__arglist) { this.Count = new ArgIterator(__arglist).GetRemainingCount(); } public static int F(__arglist) { return new ArgIterator(__arglist).GetRemainingCount(); } } ``` To generate a method that calls the static method F, we can do the following: ``` csharp public void BuildCallFMethod(TypeBuilder tb) { var mb = tb.DefineMethod(""CallFMethod"", MethodAttributes.Public | MethodAttributes.Static); var il = mb.GetIlGenerator(); il.Emit(OpCodes.Ldstr, ""one""); il.Emit(OpCodes.Ldstr, ""two""); il.Emit(OpCodes.Ldc_I4_3); il.EmitCall(Opcodes.Call, typeof(V).GetMethod(""F"", BindingFlags.Static | BindingFlags.Public), new[]{typeof(string), typeof(string), typeof(int)}); il.Emit(OpCodes.Ret); } ``` However, if we wanted to create a type that extended `V`, despite needing to emit a `call` opcode on the constructor, we cannot use `EmitCall` and instead need to look up a symbol. This is asymmetric and is bad api design. ``` csharp public void BuildCtorForExtenderOfV(TypeBuilder tb, ModuleBuilder mb) { var ctor = tb.DefineConstructor(MethodAttributes.HideBySig | MethodAttributes.Public | MethodAttributes.SpecialName | MethodAttributes.RTSpecialName, CallingConventions.HasThis, Type.EmptyTypes); var il = ctor.GetIlGenerator(); var token = mb.GetConstructorToken(typeof(V).GetConstructors()[0], new[]{typeof(string),typeof(string), typeof(int)}); il.Emit(OpCodes.Ldarg_0); il.Emit(OpCodes.Ldstr, ""one""); il.Emit(OpCodes.Ldstr, ""two""); il.Emit(OpCodes.Ldc_I4_3); il.Emit(Opcodes.Call, token.Token); il.Emit(OpCodes.Ret); } ``` Instead, I propose we allow this overload, allowing the two calls to have the same IlGenerator code pattern. The benefit is that `EmitCall`, does some validation beforehand, where as the token variant basically only validates when you build the method/ctor. As an additional benefit, I also recommend we allow using the `OpCode.NewObj` for the first parameter of `EmitCall` as well." 4500 area-System.Net Investigate problematic Sockets assertion There is an assertion in the Socket constructor which I believe might be faulty. I've tried the same code on the desktop framework and didn't hit any issues. The assertion is on line 112 of Socket.cs: https://github.com/dotnet/corefx/blob/a22364202c6d6cabeeb662fde346941b7284a8da/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L112 ``` CSharp Debug.Assert(addressFamily != AddressFamily.InterNetworkV6 || !DualMode); ``` I hit this assertion on CoreCLR when instantiating a Socket with the following args: ``` CSharp new Socket(AddressFamily.InterNetworkV6, SocketType.Raw, ProtocolType.IcmpV6); ``` (NOTE: You have to run as admin or the above will throw some other exception.) cc: @CIPop , @pgavlin 4501 area-System.Net XPlat: System.Net.Socket.Poll(0, SelectMode.SelectError) provides incorrect results On Linux, the call to System.Net.Socket.Poll(0, SelectMode.SelectError) returns true for some cases when consumed in SqlClient. If the SqlClient ignores the Socket poll result and continues to use the socket, there is no problem reading from the socket. Based on the investigation @pgavlin figured out that this is a bug with linux Native implementation for Poll. 4502 area-System.Net Add support to HttpClient for mutual authentication On the desktop, WCF uses mutual authentication when using Kerberos authentication. We specify the servers SPN by adding the relevant SPN to `AuthenticationManager.CustomTargetNameDictionary`. We need a way to: 1. Enable mutual authentication 2. Override the SPN we expect the server to be using The second item is needed if mutual auth is enabled as on the service side only a system process is able to use the host/hostname SPN. When the remote service is using HTTP.SYS in a non-system process and not using Kernal mode authentication, a unique SPN must be created and used. If mutual auth is enabled, this would break without being able to specify the SPN for the server on the client side. 4503 area-System.Data sni.dll can't be loaded on Win 7/2008R2 This issue is not the same as [this one](https://github.com/dotnet/corefx/issues/3760) because I already have the C++ runtime installed.

The size is actually `uint`, but it is typed as `long` because public APIs use `long` for CLS compliance. This field can be changed to `uint` to save 4 bytes. - `StringRepresentation` is a cache of the result of `ToString()` and can remain as-is. - `_family` indicates whether the `IPAddress` instance is an IPv4 address or an IPv6 address through the `AddressFamily.InterNetwork` (IPv4) and `AddressFamily.InterNetworkV6` (IPv6) enum values. We can eliminate this field and instead use the `_numbers` field, which is only used for IPv6 addresses, to indicate whether or not the address is IPv4 vs. IPv6. This saves 4 bytes. - `_numbers`, as mentioned in the previous bullet, is only used for IPv6 addresses. Note that currently the array is always being allocated, even for IPv4 addresses. We can change this to only allocate the array for IPv6 addresses. When the field is null, it indicates that the address is an IPv4 address, when the field is non-null it is an IPv6 address. - `_scopeId` is only used for IPv6 addresses. Similar to `Address`, the size is actually `uint`, but it is typed as `long` because public APIs use `long` for CLS compliance. We can eliminate this field and instead use the same `uint` field as `Address` for IPv4 addresses, reducing the size by another 8 bytes. - `_hashCode` is only used for IPv6 addresses (IPv4 just uses the `Address` for the hash code). We could consider getting rid of this field, to reduce the size by another 4 bytes, and instead always re-calculate the hash code when `GetHashCode` is called (all it's doing is calling `StringComparer.OrdinalIgnoreCase.GetHashCode()` on a cached `ToString()` result), but I assume it is here for performance reasons, so I've kept it for now. Here are the fields after the changes: ``` C# private uint _addressOrScopeId; private readonly ushort[] _numbers; private string _toString; private int _hashCode; ``` From 40 bytes to 24 bytes (64 bit). (Note: I renamed some of the fields and made them all private. The two renamed internal fields (`Address` and `StringRepresentation`) now have internal properties with the same type and name as the old fields, to avoid breaking any internal callers.) (There are other potential optimizations for `IPAddress` that could be handled in separate PRs. For example, `ToString()` could be optimized to avoid unnecessary intermediate allocations. Also, as noted in #2891, some means to access to the internal buffer to avoid unnecessary `byte[]` allocations could be added.) 4525 area-System.Net Address PR feedback for System.Net.Requests - Remove unnecessary string.Format in WebException - Replace several string.Compare calls with string.Equals - Improve FromAsync usage in WebRequest cc: @pgavlin, @CIPop, @davidsh Fixes https://github.com/dotnet/corefx/issues/2409 4526 area-System.Net Disable three System.Net.Security tests that repeatedly timeout https://github.com/dotnet/corefx/issues/4467 cc: @CIPop, @davidsh 4528 area-System.Net Port more System.Net.WebSockets.Client tests Continued porting internal ToF tests to GitHub.

Change type from `class` to `struct`. Either approach halves the number of allocations, second is safer but allocates more memory.

A good example for the suggested naming and structure guidelines are tests in the System.Net namespace. Examples include suffixing test classes with `Test` and naming test methods in the format `UnitOfWork_StateUnderTest_ExpectedBehaviour()`. Edit: I think that this is the book recommended by the corefx team for unit testing standards http://www.amazon.co.uk/The-Art-Unit-Testing-Examples/dp/1933988274 For example the `String` test class should be renamed to `StringTest`. A method named `TestContains` should be renamed to `Contains_String_MatchesExpected` and `TestContainsInvalid` to `Contains_InvalidInput_ThrowsException`. Why this could be good: - Matches suggested naming standards for .NET unit tests - Modernises the test suite - Consistency with other unit tests in the project - Easier to understand what tests do for debugging, test changes or future test additions - Reasons of perfectionism Why this could be undesirable: - Renaming existing tests or test classes could be a breaking change - Could break parity with the full .NET Framework - Could cause merge conflicts and extra hassle for the team If the good people of GitHub and the corefx team see this as desirable, then I shall submit a pull request to modernize this System.Runtime.Tests suite.

" 4544 area-Meta Presence of project.json breaks existing csproj tooling (and makes unexpected demands) "I'm trying to transition multiple libraries to CoreCLR, moving to the DNX build tools. Since the folder name defines the assembly/package name (not editable), and since `**/*.cs` is the default inclusion list, the natural thing to want to do is to add a project.json _alongside_ the pre-existing csproj. This is particularly valuable where not all parties are yet working with DNX. Things go south very quickly, though, with errors from nuget package restore including errors about ""runtimes"", having to add explicit version numbers to project references, and complains about projects targeting multiple frameworks (which gets generated into `{projectt}.nuget.targets`). Short term, `del project.json /s`, `del project.lock.json /s` (and `del *.nuget.targes /s` if you have already failed once) makes everything work - so it is the mere presence of those files that makes the csproj unhappy. And obviously you need to not push those deletions back to source control! This means that the only way to transition to DNX tooling alongside csproj is: - have the `project.json` in the `{ProjectName}` folder - have the csproj in a _different_ folder - edit the csproj to pick the files up from outside the tree, ideally using `""../{ProjectName}/**/*.cs""` so no more edits will be needed - (note you can do the same from `project.json`, but if you do that the IDE doesn't show them, where-as this at least does) - accept the fact that adding new files via the csproj is a ""no-no"" It is a bit of a faff. Am I doing something insanely wrong here? I know csproj alongside project.json isn't the ideal end goal, but we live in the real world where most people aren't using pre-RC software ;p " 4553 area-System.Net Ping is internally posting back to the original SynchronizationContext Several issues to be fixed: 1.

As a result of that wrapping, completion of the task requires posting back to the original synchronization context. 4554 area-Serialization Fix XmlSerializer writes empty element when serializing TimeSpan XmlSerializer writes empty element when serializing TimeSpan because this type's properties and fields are get only.

The .NET full API for DbProviderFactory contains usage of DataTable, so I recon that's not going to be ported anytime soon, but there's a bigger problem: most provider factories are defined in machine.config, which with 'bcl per app' isn't going to fly anymore. Have there been any design thoughts on this? Will .NET core have DbProviderFactory machinery so an ORM can obtain the factory from a central API (I couldn't find the API of .NET full in corefx at the moment), and create ADO.NET elements using that factory? Or is this in limbo just like DataTable (https://github.com/dotnet/corefx/issues/1039) 4574 area-System.Security Desktop Compat: GetECDsa*Key doesn't check the KeyUsage values In Desktop GetECDsaPublicKey and GetECDsaPrivateKey will return null when KeyAgreement is the only KeyUsage value specified.

So it means that if you call `ToString()` on an object for debugging/logging purposes you may get something useful or you may just get the default which is the fully qualified `Type` name. To see how widespread this is, I wrote a [simple app using Cecil](https://gist.github.com/mattwarren/33edc6d07ea087542ccb) (please let me know if [my logic is wrong](https://gist.github.com/mattwarren/33edc6d07ea087542ccb#file-clrtostringoverrides-cs-L91-L107)). Here's the lists of types that don't override ToString(): - [Value types](https://gist.github.com/mattwarren/1dc37901be49a18a7204) and a [shorter summary](https://gist.github.com/mattwarren/afba4b325f02e66db419) - [Reference types](https://gist.github.com/mattwarren/3bcecf5d2b9810c48b41) and a [shorter summary](https://gist.github.com/mattwarren/79cc5669e1e4ebae6a46) Is there any desire to be more consistent across types or is it not something that people worry about? Is it expected that `[DebuggerDisplayAttribute]` should be used instead? For instance in Java you can call ToString() on an object and you always gets something meaningful back.

Then when Task-based Async Pattern (TAP) was added to it, the Task-based implementation was done in a quick manner on top of the EAP implementation. And now that Ping is being exposed in corefx, it only has the TAP implementation. There are several ramifications of this and issues to be addressed: - The Task-based implementation is suffering from some of the behaviors of the EAP implementation, e.g. completing the Task requires posting back to the original synchronization context, which both is inefficient and can cause problems for a caller that blocks waiting for the result. - There's lots of unnecessary code now in Ping. - There are members being exposed as public and protected that aren't part of the contract. - When a host name is provided, an extra worker is being queued and then synchronously blocked waiting for the results of the DNS lookup. This PR fixes all of that. It also adds some more tests. cc: @mellinoe, @CIPop, @davidsh Fixes #4553 4622 area-System.Data Investigate why InnerExceptions for SNI SqlExceptions only have top line in stack trace 4624 area-System.Net Add some validation/sanity tests for usage of the Unix ping command line tool I wrote a basic validation test for our usage of the ping command line utility in System.Net.Utilities. I am validating that we only send a single ping, and that we send the correct number of bytes in our packet. This will give us some basic assurance that, at the very least, the machine's ping utility is usable, supports the options we are using, and its output can be parsed as we expect. I also noticed this issue after writing the test: - It appears that ping6 on OSX does not allow you to specify a 0-length packet size for whatever reason, even though you can do so with ping (IPv4 version of the utility), as well as with ping6 on Ubuntu. Because of that, I just send a packet size of 1 instead. cc; @CIPop, @stephentoub 4628 area-System.Net System.Net.Sockets.Tests.ConnectExTest.Success failure on Linux "http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst_prtest/4500/testReport/ Hit a failure in this test: [System.Net.Sockets.Tests.ConnectExTest.Success](http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_debug_tst_prtest/4500/testReport/System.Net.Sockets.Tests/ConnectExTest/Success/) Exception in question: `System.Net.Sockets.SocketException : Unknown error 10048` Seems to indicate a ""Address In Use"" error, so perhaps this is a timing issue from multiple tests trying to open the same socket, or something of the sort.

Hi there, For `System.Threading.Thread : 4.0.0-beta-23516`, there appears to be a problem having the thread execute as a foreground thread on DNX (`1.0.0-beta6-12120`). The property `IsBackground` does not appear to have any bearing on how this thread is treated, with it seemingly behaving like a background thread with `IsBackground` reporting false. The end result is the caller must explicitly join on the thread to prevent a process exiting, which is not typical behavior. I am mindful that this may be related to DNX, or potentially functionality under review for corefx with consideration to varying platforms. MSDN: CLR Thread.IsBackground Property https://msdn.microsoft.com/en-us/library/system.threading.thread.isbackground%28v=vs.110%29.aspx Below, the expected behavior would be to have the process stay running until this thread exits. ``` csharp using System; namespace example { public class Program { public static void Main(string[] args) { // 4.0.0-beta-23516 var t = new System.Threading.Thread(() => { var running = true; while(running) { // we do not want this thread to exit. } }); t..Start(); // t.Join(); // this shouldn't be necessary for IsBackground = false } } } ``` Many Thanks 4638 area-System.Xml Wrong encoding when using XmlTextWriter Hi, does anyone know how to do the following with .NET core? ``` using (XmlTextWriter sw = new XmlTextWriter(this.FilePath, new UTF8Encoding(false))) { sw.Formatting = Formatting.Indented; sw.Indentation = 1; sw.IndentChar = '\t'; this.XmlDocument.WriteTo(sw); } ``` Kind regards 4641 area-Serialization Add support for surrogate for XmlSerializer 4642 area-Serialization Add support for surrogate in DataContractJsonSerializer 4646 area-System.Data Request for clarification on System.Data DbDataRecord / DbDataReader "`DbDataReader` has a `GetEnumerator()` API which is intended to return an `IEnumerable` that exposes `IDataRecord` (often: `DbDataRecord`) - this is often implemented via `DbEnumerator`. On core-clr at the current time, `DbDataReader` has an `abstract IEnumerator GetEnumerator()` method that must be overridden. However, without `DbDataRecord` or `DbEnumerator`, it is unclear how this is meant to be done in any way. I've checked the `SqlDataReader` code, and it currently refers to a local copy of a publicly declared `DbEnumerator` (et al), but these public declarations do not seem to be accessible on the currently published packages. So; can someone clarify this? a: is this `abstract` method an accidental inclusion that should have been dropped in the core-clr API? or b: is this meant to be there, but the required APIs to do it are in the wrong place and not yet available? Assuming ""b"", is there a timescale to get this into place so we can verify again the proposed API?

Note that I'm using Windows 10 build 10586 but I've also reproduced the issue on Linux (Ubuntu and CentOS). It _seems_ to me that only responses with a larger body will crash. Metallica triggers the crash, but so does ""Queen"" for instance. Artists with a shorter content response seem to never crash. Just a thought, maybe it's unrelated.

This is important for binary serialization tools to get hold of the underlying value without requiring unsafe themselves, which may not be accepted. Example usage: IO / sockets tools, raw protocol tools, network libraries, serialization tools. ## Existing 64-bit API ``` public static long BitConverter.DoubleToInt64Bits(double value); public static double BitConverter.Int64BitsToDouble(long value); ``` However, no 32-bit api exists ## Proposed 32-bit API To mimic existing API: ``` public static int BitConverter.SingleToInt32Bits(float value); public static float BitConverter.Int32BitsToSingle(int value); ``` ## Rationale and Usage Exactly the same as pre-existing 64-bit API: - caller can populate an `int` (perhaps via shift ops and network access / stream, perhaps via raw memory access), and force it to a `float`, for example during deserialization - caller can consume a `float` and force it to an `int` (perhaps for use on network access / stream via shift, perhaps via raw memory access), for example during serialization ## Details To follow same rules and conventions as the existing 64-bit api, which is to say: uses straight unsafe cast - does not explicitly consider machines where integer and floating-point endianness are different (integer big-endian, floating-point little-endian), but is fine on both big-endian and little-endian machines - in reality the endianness matches. To emphasise: there is nothing in here that is different from the expectations of the existing 64-bit api. It would be inconsistent to have the 32-bit API operate with different expectations to the 64-bit api, and it would be a breaking change to alter the expectations of the existing 64-bit api. ## Pull Request A pull request is available with the proposed implementation (comments etc based on the existing 64-bit API): https://github.com/dotnet/coreclr/pull/833 ## Issues None known; not a breaking change, and no overload resolution issue since uniquely named static non-extension methods. ## Discussion Point Possible doubt over relevancy of comments and assertion.

If a `Task` is needed, one can be retrieved using `ValueTask`'s `AsTask()` method, which will either return the `Task` it stores internally or will return an instance created from the `T` it stores. 4717 area-System.Reflection Fix decoding of varags method references We were peeking at the sentinel between required and variable arguments, but not consuming it.

ALPN support [is available](https://technet.microsoft.com/en-us/library/hh831771.aspx) in SChannel for Windows Server 2012 R2, Windows 8.1 or later. Support in SslStream is a popular feature request: See [here](https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/6264363-add-support-for-alpn-to-system-net-security-sslstr) and #2928. Client and server applications need a way to specify their supported application protocol list and be able to query the negotiated protocol. ## Proposed API change ``` C# public partial class SslStream : AuthenticatedStream { ... public virtual void AuthenticateAsClient(string targetHost, System.Security.Cryptography.X509Certificates.X509CertificateCollection clientCertificates, System.Security.Authentication.SslProtocols enabledSslProtocols, bool checkCertificateRevocation, string[] applicationProtocols); public virtual System.Threading.Tasks.Task AuthenticateAsClientAsync(string targetHost, System.Security.Cryptography.X509Certificates.X509CertificateCollection clientCertificates, System.Security.Authentication.SslProtocols enabledSslProtocols, bool checkCertificateRevocation, string[] applicationProtocols); public virtual void AuthenticateAsServer(System.Security.Cryptography.X509Certificates.X509Certificate serverCertificate, bool clientCertificateRequired, System.Security.Authentication.SslProtocols enabledSslProtocols, bool checkCertificateRevocation, string[] applicationProtocols); public virtual System.Threading.Tasks.Task AuthenticateAsServerAsync(System.Security.Cryptography.X509Certificates.X509Certificate serverCertificate, bool clientCertificateRequired, System.Security.Authentication.SslProtocols enabledSslProtocols, bool checkCertificateRevocation, string[] applicationProtocols); public virtual string NegotiatedApplicationProtocol; } ``` (New method overloads of `AuthenticateAsClient`/`AuthenticateAsServer` (+their async versions) are being added having new parameter `string[] applicationProtocols`. New property `string NegotiatedApplicationProtocol` is added as well). Full view of SslStream API containing the proposed changes is in [PR](https://github.com/jubarat/corefx/blob/sslstream_alpn/src/System.Net.Security/ref/System.Net.Security.cs). ## Example usage Client: ``` C# SslStream sslStream = new SslStream(serverStream); string[] applicationProtocols = new[] { ""h2"", ""http/1.1"" }; sslStream.AuthenticateAsClient(certificate.Subject, new X509CertificateCollection(), SslProtocols.Tls12, false, applicationProtocols); string protocol = sslStream.NegotiatedApplicationProtocol; ``` Server: ``` C# SslStream sslStream = new SslStream(serverStream) string[] applicationProtocols = new[] { ""h2"", ""http/1.1"" }; sslStream.AuthenticateAsServer(certificate, false, SslProtocols.Tls12, false, applicationProtocols); string protocol = sslStream.NegotiatedApplicationProtocol; ``` ## Details Client advertises list of protocols in descending order of preference. After the TLS handshake is complete the client queries the TLS stack for negotiated application protocol. Similar way server side application provides its own list of supported protocols (again in descending order of preference). The TLS stack makes the application protocol match internally. After the handshake completes the server application queries the negotiated application protocol. Note: This behavior is supported by SChannel and is compatible with OpenSSL ALPN API. Unlike OpenSSL the SChannel does not expose possibility of querying client's advertised list of protocols therefore this API proposal does not contain server side protocol selecting based on callback. `AuthenticateAsClient`/`AuthenticateAsServer` methods - null value passed to `applicationProtocols` parameter means the caller is not requesting application protocol negotiation. This is also the behavior of existing method overloads. - If both client and server specified their application protocol list and there was no match then `AuthenticateAsServer` throws `AuthenticationException` with inner exception having OS native error code. At this point the TLS handshake is aborted so the client gets `IOException` due to server application closing the transport connection. - An alternative approach how to pass application protocol list instead of `AuthenticateAs…` methods could be as parameter of SslStream constructor. - In following cases `ArgumentException` is thrown: - Empty protocol list. - Any element of protocol list is null. - Any element has more than 255 characters. - The full protocol list serialized size is more than 32767 bytes. `NegotiatedApplicationProtocol` property - If successfully negotiated then it returns the negotiated application protocol string. - If peer did not advertise ALPN TLS extension or `applicationProtocols` was null then this property returns null. - Throws `InvalidOperationException` if calling before `AuthenticateAsClient` or `AuthenticateAsServer` completes. Examples of API behavior are in [functional tests](https://github.com/jubarat/corefx/blob/sslstream_alpn/src/System.Net.Security/tests/FunctionalTests/ApplicationProtocolNegotiationTest.cs) of PR. ## Pull request #4685 " 4722 area-System.Linq Public Surface of System.Linq.Expressions.Expression exposing too much?

They are not documented, nor public in any of the other .Net versions. I can't see any trace of a decision to make them public here, and the blame record suggests they were imported as such. With the possible exception of `DebugView`, they don't seem particularly useful to outside code or if they are they should perhaps be defined elsewhere. Also, `RequiresCanWrite` remains private and should surely be public if `RequiresCanRead` is. This looks like it was introduced by accident in a refactoring of some of these methods into `ExpressionUtils` that happened in between the release of .NET 4.6 and the code being brought into dotnet/corefx (or in a different branch, etc.). If I'm correct in deducing that their access is a mistake, removing the access to them would be a breaking change, but by the same token should perhaps be done as soon as possible before more dependencies on them appear. 4724 area-Serialization [.Net Native] XmlTextAttribute on a primitive type property in struct seems not to be supported "This problem only occur when the c# code was compiled by .Net Native tool.

In the Debug mode, the code is run on CLR, it works perfectly. But in the release mode, the code is compiled into native code. When it is going to Serialize or Deserialize, it crashs. But I can modify my code: ``` public class FieldWithDateTime//change from struct to class ``` And then, Compile it, it works perfectly. So, if FieldWithDateTime is a class, the code can work both in Debug or Release mode, but if FieldWithDateTime is a struct, the code can only work in Debug mode.

The detailed notes are here: https://github.com/dotnet/apireviews/pull/21 Filing this issue to track the following proposed changes based on API review feedback: - [x] In `WebException` in the System.Net.Requests contract: For the constructors, change parameter name `inner` to `innerException` to match that in .NET Framework - Done #4740 - [x] In `WinHttpHandler.ServerCertificateValidationCallback`: Document/add comments for the meaning of each parameter - Documentation bug referred to MSDN doc team. Update - Added this here: https://msdn.microsoft.com/en-US/library/mt345545(VS.105).aspx - [x] In types `NegotiateStream` and `SslStream`: Remove synchronous versions of `AuthenticateAsServer` and `AuthenticateAsClient` methods - Done #4868 - [x] In `System.Net.Utilities` contract: Consider if we want it to be a bag of multiple utilities OR more scoped down to just ICMP-related utilities. If scoped down, consider renaming the contract - Done #5232 renamed the contract to `System.Net.Ping` - [x] Cancellation support: Add CancellationToken overloads to appropriate async methods in all contracts – e.g. `System.Net.Sockets`, `System.Net.Security` - Deferred #5211 - [x] In `enum SocketFlags`: Remove value `MaxIOVectorLength`, but document that slot 16 should not be used since it will cause conflict with .NET Framework - Done #4888 - [x] In `enum SocketOptionName`: Add ReuseUnicastPort support. This is a new option added to .NET Framework 4.6 to improve server scalability and is currently missing from .NET Core. - Done #4888 - [x] In structs `SocketReceiveFromResult` and `SocketReceiveMessageFromResult`: Investigate if the individual fields be properties. - Investigated. Final decision is to leave it as-is with public fields. 4733 area-System.Net System.Net.Sockets.Socket.DoConnect() doesn't work as expected.

Part of #4732 4750 area-System.Linq Improve Enumerable.Reverse() performance for IList and LinkedList I would like to suggest and discuss a possible performance improvement of the Enumerable.Reverse() extension function in the System.Linq namespace. Currently a _Buffer_ struct is created that allocates a new array of elements in most cases, as can be seen here: ``` csharp internal struct Buffer { internal TElement[] items; internal int count; internal Buffer(IEnumerable source) { IArrayProvider iterator = source as IArrayProvider; if (iterator != null) { TElement[] array = iterator.ToArray(); items = array; count = array.Length; } else { items = EnumerableHelpers.ToArray(source, out count); } } internal TElement[] ToArray() { //... } } ``` For the ReverseIterator the _items_ array of the _Buffer_ struct is then iterated through from end to start. I would think that the array allocation is not always needed, so I suggest to handle the reverse iteration of _IList_ and _LinkedList_ differently. An _IList_ object could be directly used for reverse iteration like the buffer struct but without creating and allocating the in this case unneccesary buffer first. For _LinkedList_ sources the reverse iteration would be easily possible without a _Buffer_ too. So what do you think about this? Am I missing a good reason here why this has not been done already? I could imagine the argument that Enumerable cannot handle every special collection differently, but at least _IList_ is often treated special. Oh and btw: I think this ``` csharp TElement[] array = iterator.ToArray(); items = array; count = array.Length; ``` should be ``` csharp items = iterator.ToArray(); count = items.Length; ``` as I don't see a reason for introducing the variable _array_. 4754 area-System.Net HttpClient doesn't respect HttpRequestMessage.Version e.g. if it's set to 1.0, the request still gets sent with a version 1.1 4756 area-System.Net Add HTTP/2 support to HttpClient on Unix The latest versions of libcurl have HTTP/2 support; this commit enables that to be used from HttpClient via setting the request Version. Setting the Version will now pass along that version preference to libcurl; if it's set to 2.0, libcurl will use HTTP/2 if supported, otherwise it'll fall back to its default (1.1). As part of this I also fixed CurlHandler to pass along v1.0 and v1.1 so libcurl can respect the developer's explicit wishes. (Note that the HTTP/2 light-up is only available if libcurl supports it. libcurl relies on nghttp2, which needs to be installed, and a version of libcurl needs to be used that's built against it. To test, I built these locally from source.) cc: @vijaykota, @kapilash, @davidsh, @cipop, @eerhardt 4757 area-System.Net Updating and locking project.lock.json for Security UnitTests.

This follows the precedent of blob-decoding done for Portable PDBs, makes the API more discoverable, and eliminates questions around which API to call for which blobs, which was exacerbated by the weak typing of BlobHandle. SignatureDecoder.DecodeXxx now all take ref BlobReader alone. Convenience overloads to allow parsing byte sequences without forcing the caller to pin and use pointers should be added, but that is deferred until `Span` arrives. - Remove ISignatureTypeProvider.Reader and instead pass along the metadata reader to the provider whenever there is a handle. The reader is allowed to be null (to decode byte sequence that didn't come from a metadata reader, which our tests do). Many type providers will already capture the metadata reader so that they have enough context in other situations than resolving handles (e.g. interpreting generic parameters beyond their index.), but this duplication is harmless and it simplifies the API. - Change CustomModifier handling to happen one-at-a-time and give the provider the raw handle rather than a decoded TType so that modifiers are cheaper to skip, and so that we do not traverse in to typespec signatures on provider's behalf. - Make class/value-type differentiation optional and handle WinRT projections correctly when enabled. - Add considerably more doc comments. - Add significant test coverage. All blocks in the SignatureDecoder with the exception of WinRT class <-> value type projection (I'll write some tests for that shortly) are now covered. - Use ImmutableArray.Builder.MoveToImmutable throughout to eliminate unnecessary copying. - Move everything in the Decoding folder to the Decoding namespace. (Some types being in the root was unintentional.) - Add specific error messages to all BadImageFormatException throws. NOTE: - A change to make it possible for the context-carrying provider to be passed around as an unboxed struct (reducing allocation) was attempted and reverted. The API is complex enough and the extra type parameter that could not be inferred was quite cumbersome. The Decoding namespace is given more freedom than the rest of S.R.M to allocate. In typical scenarios, symbols are parsed once and cached. - The type name parser and custom attribute decoder still need more refactoring and testing and will not be submitted to master just yet. FYI: @tmat, @michaelcfanning -- I'm going to turn around and submit this (minus type name and custom attribute decoding) as a PR to master (along with API review materials), so I'll merge to the dev branch once CI is green. 4771 area-System.Net System.Net.Sockets Build Failure (VS2015/Win10) Steps to reproduce: 1. git clone https://github.com/dotnet/corefx (OK) 2.

I understand that this is light-up code, but is there a reason that we have this requirement instead of using a different method that doesn't include this dependency? cc @ericstj 4786 area-System.IO Mechanism for reading directly from file to unmanaged memory System.Reflection.Metadata has an optimization where it reads files small enough to not warrant memory mapping directly into the unmanaged heap (without an intermediate copy on the managed heap). This optimization is done by lighting up on Windows to the native `ReadFile` API. For this to work cross-plat there should be a way to pass unmanaged memory to Stream and have FileStream override it to not involve intermediate copies to managed memory. This could possibly be accomplished via `Span` support in `Stream` overridden by `FileStream`. cc @KrzysztofCwalina 4792 area-System.IO Add Path.TryGetExtension Today Path.GetExtension throws if the value passed in has invalid chars.

From my understanding this was deemed acceptable because OSX already has a stable Application Binary Interface (ABI). However, looking through some of these calls, I'm not completely sure this is true. For example https://github.com/dotnet/corefx/blob/master/src/Common/src/Interop/OSX/Interop.CoreFoundation.cs#L72-L77 has : ``` C# private static extern SafeCreateHandle CFArrayCreate( IntPtr allocator, [MarshalAs(UnmanagedType.LPArray)] IntPtr[] values, ulong numValues, IntPtr callbacks); ``` Which on my Mac appears to be defined as: ``` C++ CFArrayRef CFArrayCreate( CFAllocatorRef allocator, const void **values, CFIndex numValues, const CFArrayCallbacks *callbacks); ``` And where `CFIndex` is defined as: ``` C++ #if __LLP64__ typedef signed long long CFIndex; #else typedef signed long CFIndex; #endif ``` Are we guaranteed that CFIndex will always be an 8-byte integer? What if we were on a 32-bit OSX? We should analyze all our non-shimmed native calls on OSX and be 100% sure we will always have ABI stability, no matter the OSX system we are running on. 4801 area-System.Net GetAsync_ResponseHeadersRead_ReadFromEachIterativelyDoesntDeadlock failed on CentOS in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx_linux_centos71_debug_tst/166/console ``` 07:38:26 System.Net.Http.Functional.Tests.HttpClientHandlerTest.GetAsync_ResponseHeadersRead_ReadFromEachIterativelyDoesntDeadlock [FAIL] 07:38:26 System.Threading.Tasks.TaskCanceledException : A task was canceled. 07:38:26 Stack Trace: 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() 07:38:27 at System.Net.Http.Functional.Tests.HttpClientHandlerTest.d__94.MoveNext() 07:38:27 --- End of stack trace from previous location where exception was thrown --- 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 07:38:27 --- End of stack trace from previous location where exception was thrown --- 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) 07:38:27 --- End of stack trace from previous location where exception was thrown --- 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) 07:38:27 at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) ``` 4802 area-System.Data Windows 8 support for System.Data.Common According to [this](https://github.com/aspnet/Microsoft.Data.Sqlite/issues/185#issuecomment-161726607) issue, `System.Data.Common` needs to support Windows 8 before `Microsoft.Data.Sqlite` can.

That version of libcurl is from before HTTP/2 multiplexing was introduced. When multiplexing was added to libcurl, one of the existing libcurl functions (curl_multi_setopt) was changed such that if you were to pass in the HTTP/2 multiplexing option (which didn't exist at the time), due to the way the method was implemented, you'd end up opting in to HTTP 1.1 pipelining rather than having the option just be ignored. This is not the desired behavior and ends up breaking behaviors where we issue multiple HTTP 1.1 calls on the same multi handle concurrently. This fix exposes from the native shim whether we're using a version of libcurl that supports HTTP/2 and that knows about the multiplexing option, and only configures the multi handle for multiplexing in that case.

For instance, OS X and Ubuntu generate Changed events on the root watch folder while Windows does not; or, on OS X, unlink and link (aka a FileSystem Move) causes a metadata change on the parent folder. Smoothing out some of the above scenarios (aka making them consistent across each platform) can get quite complicated due to the underlying non-deterministic basis of each FSW API. None of the supported OS kernels (Linux Kernel, Darwin, or NT) make a guarantee that callers will receive all notifications or notifications in a timely manor, due to internal buffers and system load. Theoretically, each underlying File System **could** also generate events differently (ie ext3 to ext4); it may not, but that would require more intensive testing. Consumers of the FSW, anecdotally from my past experience, will usually have state machines to determine what actually changed based on certain notifications or notification patterns. Trying to fit each platforms nuances into one single pattern would require a quite intricate state machine to handle some of the edge case situations that can occur, such as a delay between the unlink and the re-link notifications due to system load or a full buffer; therefore, I'd propose that we allow the FSW classes to be best-effort and acknowledge that minor differences will happen cross-platform (for example, an extra Change notification on OS X due to unlink and re-link behavior) as long as the differences do not cause dramatic functional differences to consumers.

In particular: - .NET 4.6 does not supply many of the preferred algorithms for IETF protocols - The organization of the APIs is haphazard and inconsistent. I know that there are several comments on this and an expectation that 'something' will be done. I would like to make some suggestions. First, for algorithm selection, note that IETF just started a call for comments on a new working group to choose a consistent set of algorithms for use in IETF protocols. So the idea is that S/MIME, TLS, SSH, OpenPGP, etc. all use the same set of algorithms. This is not a completely open ended process either as pretty much anyone involved in that process can tell you right now that you are not going to need anything outside: Encryption/Integrity: AES-CCM, AES-GSCM, AES-CBC in 128 and 256 bit strengths ChaCha20 and Poly1305 Digest: SHA2 and SHA3 Public Key: Key agreement (ECDH) and digital signatures (EdDSA) with Curve25519 and Curve448 as defined by CFRG RSA signature and encryption at 1024 and 2048 bit key strengths. It will take at least 18 months to get documents out that describe in detail how these are applied in all the application protocols. But that is the set of algorithms we are trying to establish as standard across the board. On the API side, there is a lot of inconsistency right now and the current classes are really not well suited for use with the encrypt-plus-authenticate modes we prefer in modern protocol design. The classes for encryption, authentication and public key ops expose different functionality at different layers in the inheritance hierarchy. They don't expose the identification info we need for interface with certificates, or S/MIME, JOSE, etc. So what I have done for my own code is to develop a set of classes that essentially wrap the .NET classes which in turn wrap either the Windows classes or OpenSSL. I also have a much simpler certificate parser/issuer library that is in native C#. Both of those will be released as open source under an MIT license in the next few days. Right now my project is built in .NET 4.6 because it is what existed. But the aim all along was to move to .NET Core, that was part of the reason for choosing .NET in the first place. 4867 area-System.Diagnostics EventSource dictionary events are broken on CoreCLR "Writing a dictionary to an EventSource like the following is broken. `EventSource logger = new EventSource();` `logger.Write(""EventWithStringDict_C"", new { myDict = dict, s = ""end"" });` This fails because Activator.CreateInstance fails because it can't find the constructor for one of the types we use in TraceLogging to parse the dictionary.

Note: The .NET Framework (Desktop) will throw an exception if neither 1.0 nor 1.1 version is specified.

This goal is completely orthogonal to the pain points I listed. Inter-project dependencies are a fact and attempting to solve the granularity problem (Packages or not) by trading in developer productivity is simply a mistake, and if you insist to compare apples to oranges than aiding to code comprehension is by far more important to correctness. Technically there is nothing that prohibits someone from directly referencing any other project (csprog) . (something which is already being done between existing projects in the corefx repo). What constitutes the right level of package isolation can only be determined by peer code-review not the build system. Suggesting that independent build scripts solve the problem is a misunderstanding of the problem because build scripts are also modified to create dependencies just in a less visible way. > For cases were folks have a desire to run tests against the live versions of all the dependencies built in the repo people can pass /p:TestWithLocalLibraries=true when building test projects Building unit tests is a minor problem and has nothing to do with this issue. The fundamental problem is Navigating the source (Goto To Definition) and Debugging (Step Into) _across different implementation projects and test projects using Visual Studio_ again, aiding to code comprehension should be a key requirement. (WinDbg - Forget it!) We need to automatically generate a solution that references projects (csproj) that live in parallel to the independent existing project csproj. What gets into final Nuget packages or specified in the project.json is a completely different issue. Failing to address this is a pushback to potential contributing (a.k.a volunteering) efforts - a financial lose for the project. 4925 area-System.Security Add PackageTargetRuntime to System.Security.Principal.Windows to name supported OSes Update the .csproj in System.Security.Principal.Windows to specify for only the runtimes it supports.

This is the wrong behavior for the following reasons: - Existing code written for the desktop may fail with an exception - There's no compile time error when writing code which is guaranteed to fail at runtime - An exception can be thrown even when SSL3.0 wouldn't be used even though specified - Inconsistent behavior with other mechanisms to disable SSL3.0 **Existing code written for the desktop may fail with an exception** Any code written for the desktop which specifies SSL3.0 will now throw an exception, but the developer may not discover this until after code has been released. If a third party library developer is able to port their code to core clr with minimal changes, they may not test every code path in their library on core clr. This is becoming more and more likely now that we support Linux and OSX as many developers won't have the capability to verify their code on those platforms. They should be able to expect that as long as the api surface is available, that their code will behave the same on all platforms that support the api. **There's no compile time error when writing code which is guaranteed to fail at runtime** If I create an SslStream and try to authenticate to a remote host specifying SSL3 | TLS | TLS11 | TLS12 in a call to AuthenticateAsClient, this method call is now guaranteed to fail at runtime 100% of the time. That code is deemed invalid and yet there's no compile time warning or error. This is a bad developer experience. **An exception can be thrown even when SSL3.0 wouldn't be used even though specified** On desktop and with the prior behavior, if I pass the list SSL3 | TLS | TLS11 | TLS12 to SslStream.AuthenticateAsXXXXX at both ends of a stream I'm attempting to secure, SSL3 won't get negotiated as a higher protocol will attempt to be established. This change causes an application/library which wouldn't have resulted in an insecure connection being negotiated now having a runtime failure despite still being secure. **Inconsistent behavior with other mechanisms to disable SSL3.0** Other mechanisms where SSL3.0 can't be used are the protocol being disabled at the OS level (registry change in Windows for example), or the remote end not supporting SSL3.0. In either of these cases, specifying SSL3.0 can't result in SSL3.0 being used as it's been made unavailable, and as long as other protocols have been specified the connection will be negotiated without any problem. If SSL3.0 was the only protocol specified, then an exception would be thrown stating that a secure connection wasn't able to be negotiated. Throwing a different exception because SSL3.0 has been disabled via a different mechanism (hard coded in .NET networking code) is an inconsistent response to the same basic reason (support for the protocol has been disabled for security reasons). Specifying the protocol to use is a negotiation and there's no guarantee that any one protocol that was specified can or will be used as there are other dependent factors (OS support, remote party protocol support etc). If SSL3.0 (or 2.0) is specified, simply removing it from the list passed down to lower layers (such as SCHANNEL) without any error or exception is compatible with the purpose of specifying which protocols to use in that it's a negotiation and there's no guarantee that everyone agrees to the same list. If only SSL3.0 or SSL2.0 are specified, then there are no alternatives so I could see failing fast and informing by exception that those protocols aren't supported. But in that situation you would be guaranteed a failure regardless of mechanism to disable the protocol and you wouldn't be breaking code which otherwise would continue working had a different mechanism been used to disable these protocols. When other more secure protocols have been specified, there's no need to fail the request, just don't use the insecure protocols. I would suggest having the following behavior(s): - Bitwise AND any specified protocols with the compliment of (SSL3 | SSL2) to disable their usage when applying the specified protocols (so as not to break round-tripping of property getter and setter values). - Optionally throw an exception if only unsupported protocols have been specified. - Optionally, if SSL3/SSL2 were specified along with other protocols but a secure connection was unable to be negotiated, have a special exception message noting that SSL3/SSL2 are no longer supported to give a hint to a possible cause 4928 area-System.Runtime Add StringBuilder append methods to StringBuilder.

If for example you call the Minimum property of RangeAttribute before and after calling FormatErrorMessage you might first get ""0"" then 0d (which is not a side effect one would expect without examining the source). Now you have to keep track of whether you've called that or not when looking at Minimum and Maximum so you know what to expect. I understand that throwing in setters and Attribute constructors is bad, but perhaps the work could be done in the getters so that it's never wrong and any exceptions don't break attribute construction.

At the moment this is not represented in the API surface of those types. I propose to lift that restriction. In fact most members of `List` could be made available on `Stack` and `Queue` as well. Really, `Stack` and `Queue` are mostly different ways to index and interpret an underlying array. There is no reason a `Stack` could not have for example `Remove(T)` or a `RemoveAll(Func)` methods just like `List` has. I propose in priority order: 1. Add `get` indexers to `Stack` and `Queue` 2. Add the core read and write methods that are required for users to implement the remaining ones. I think that would be `Insert`, `RemoveAt` and a `set` indexer. 3. Add as many `List` methods as seems appropriate to `Stack` and `Queue`, copying them from `List`. I don't see a reason why the set of methods to copy should be limited. We could go for feature parity. This issue seems like a good candidate for a community contribution. 4963 area-Infrastructure Top-level dir.props claims Roslyn can't build PDBs on Unix In particular, this piece of (Unix-only) code: ``` xml false none ``` ... claims that it's necessary to disable PDBs when building on Unix because dotnet/roslyn#2449 wasn't yet ready.

DbParameter implemented the IDbParameter interface which included the Scale and Precision properties. When System.Data was added to corefx, the interfaces were dropped since the abstract classes had been preferred since .net 2.0 and forward. @mgravell noticed ( #1612 ) however, that when the interfaces were removed, the Scale and Precision properties were broken. For some reason they used the interface to call the child implementation instead of traditional class inheritance. You can see the old implementation here : http://referencesource.microsoft.com/#System.Data/System/Data/Common/DBParameter.cs,68 The net result is that calling Scale or Precision on a SqlParameter object **casted to a DbParameter** is a no-op. This is the problem. # Motivation The are 3 motivators for this change. 1. Maintaining perceived behavior from the desktop framework 2. Implementing the path of least surprise 3. Enabling DB agnostic code (very important) The first point being that the following 2 statements are equivalent in .net 4.5 ``` C# SqlParameter param = new SqlParameter(); param.Scale = 1; ``` and ``` C# DbParameter param = new SqlParameter(); param.Scale = 1; ``` Whereas they are not currently equivalent in corefx. The 2nd statement will **not** update the value of Scale. The same behavior applies to the Precision property. The second motivation is that this kind of behavior difference is very unexpected. Most developers would assume that the behavior of setting or reading a property would not change due to inheritance. Lastly if you wanted to write DB agnostic code that only used the Db\* classes, you would be unable to set these parameters without a test and cast special case down to SqlParameter. # Proposed Change Simply alter SqlParameter to make Scale and Precision override the DbParameter implementations. # Risks I can see two _possibly_ breaking changes here: 1. Calling Scale and Precision from DbParameter now returns the SqlParameter implementation 2. Scale and Precision on SqlParameter are now virtual and therefore overridable The first one, is actually the existing behavior under .net. The SqlParameter members implicitly implemented the interface and get called from the parent (DbParameter) by it casting itself to the interface. The net result was the child implementation getting called. The second is not actually observable since SqlParameter is sealed and therefore no child classes can break. Now lets say that a 3rd party library was inheriting from DbParameter. They would more than likely just override Scale and Precision directly in .net. In core they could only do that, so this should not present a breaking change to existing or ported libraries. So i think that this is a safe change to make unless someone wrote code against corefx that was counting on DbParameter.Scale always being zero regardless of what they assigned it. Therefore **I believe this change has minimal risk in breaking code.** # Pull Request The changes are implemented here #4902 4970 area-System.Diagnostics An argument for dnx to set the process name _From @tuespetre on December 5, 2015 17:36_ Since ASP.NET 5 is aiming to provide a highly scalable, deployable, or otherwise 'cloud-friendly' approach to writing applications, I think it is important to discuss [the 'processes' components of the twelve-factor methodology:](http://12factor.net/processes) > ... a production deploy of a sophisticated app may use many process types, instantiated into zero or more running processes. In order to properly identify the running instances of a process, it can be useful for each process to have a distinct name. This allows processes to be easily identified through various user interfaces and command line utilities that provide information on a node's running process, and if set via command-line arguments, allows other utilities like Powershell DSC to distinguish the instances of the running processes that they are supposed to manage. I realize this can be implemented within each application with very little effort but I hadn't seen a discussion on this yet so I wanted to hear some other opinions. _Copied from original issue: aspnet/dnx#3235_ 4973 area-System.IO Re-enable DriveInfo VolumeLabel test resolves #1355 4976 area-System.Diagnostics Address reviews for porting System.Diagnostics.StackTrace to open @noahfalk Please address the comments posted to PR related to porting System.Diagnostics.StackTrace here https://github.com/dotnet/corefx/pull/4972#issuecomment-164534670 4980 area-System.Net SMTP Client does not use correct MediaType for Body when Alternate Views are Specified "Hi DotNet: I've found a bug in System.Net.Mail.

Those should really capture a `ref` to the value rather than making a copy of the value. Unfortunately, blocks don't support `ByRef` variables (if they would escape the stack frame, things would go terribly wrong of course), so options are: - do nothing and consider this behavior to be expression-specific; extension nodes for languages like C# and VB need to deal with it themselves; - make the copying behavior for receivers less aggressive; if the target is classified as a variable, the copy can be avoided (also the case of accessing a field with a mutable struct); - use a write-back approach (not desirable knowing that there are perfectly suited IL instructions to deal with reference indirection for loads and stores); - support ByRef variables in blocks which would need escape analysis in the lambda compiler to ensure verifiable code gets emitted. Obviously, any change here would be considered a breaking change. Nonetheless, this is an interesting behavior that can cause issues when layering language-specific extension nodes on top of the existing API.

The internal constructor blocks compiling a type that derives from Assembly, which would be useful thing to create for testing purposes. This forces you to take different testing strategies depending on whether the tests targets .NET Core (you have to use Moq) or desktop .NET (then you can't use Moq because of `ISerializable` but you can easily create a test double that derives from Assembly). The internal constructor in the contract may very well be intentional and I think this is a very advanced scenario, but I wanted to raise it mainly because: 1. It would be nice if you could use a uniform and simple testing strategy for both .NET Core and desktop .NET. 2. The compilation error is very annoying and obscure: It is even hard to understand what is going on by looking at the source code of the implementation. As far I am aware you have to reverse engineer the ref assembly to see the internal constructor. 3. This might actually be a leftover.

Related to #4991 @stephentoub @justinvp @mellinoe 5001 area-System.Net Fix WinHttpHandler response handling for manual cookie parsing WinHttpHandler was losing 'Set-Cookie' response headers during auto redirection handling when the handler was in 'manual cookie' mode. I.e. `CookieUsePolicy.UseSpecifiedCookieContainer`. This is the only mode that HttpClientHandler uses. The 'Set-Cookie' headers were currently only parsed out when a final HTTP response happened. This meant that 'Set-Cookie' headers present in interim 3xx redirection responses as well as interim 401, 407 auth responses would not be stored into the CookieContainer. Hence, those same cookies could not be sent back to the server when needed. The fix is to make sure we parse out the 'Set-Cookie' headers whenever we get an HTTP response back from WinHTTP.

There is still some work that need to be done to actually be able to restore .NetCore MSBuild, so the idea is to use what we have now to try to build corefx repo and start calling out the issues we find to the MSBuild so that we can get those issues addressed. For now, we are only going to use this version of MSBuild in Linux builds, since it is still not yet in the scope to support building in parallel, so that would slow the windows builds by a lot.

All of the string resources in that file are included in the assembly, even if they are not used at all, or if only a subset are used. You can ""opt-out"" in a sense by changing the directory that the resource targets look in for the ""Strings.resx"" file (the `ResourcesSourceOutputDirectory` Property). This has worked fine for our projects with a single configuration, or with only a few similar configurations. However, this can cause significant bloat in assemblies which don't need those resources. For example, full-facade projects are generally around 5-6 KB in total size. With unnecessary string resources included, they can easily bloat to 25-30 KB each. To a lesser extent, configurations which only need a subset of the resources are also bloated by having extra strings in them. In our internal build, I recall we used text files that allowed condition inclusion/exclusion of certain strings, based on the project's DefineConstants. We might want to look into something similar to that in order to accomodate this.

"Continuation of discussion from #4868 > > Without AuthenticateAsClient(), Open() must resort to calling an async method internally, which means that it's no longer purely synchronous... > > The code above is as synchronous as the old implementation. When you call synchronous I/O on something like NetworkStream, internally, the thread will be waiting on an event for the operation to finish. Even more broadly: in reality there is no such thing as synchronous I/O in Windows. Thanks for this detail. I was aware that at least in some cases sync methods actually perform async operations under the hood. However, coming from the Unix universe, it doesn't seem to hold that there's ""no such thing as synchronous I/O"" at least at the kernel level: I would expect .NET I/O operations to map to simple sync I/O system calls such as write and read. Also, the implementation details underlying async operations across platforms may make sync I/O more attractive at least in some cases (i.e. is async I/O implemented efficiently on Linux with mono, or with coreclr for that matter?). I admit I'm just asking questions, I don't have enough solid knowledge here. Regardless of these questions, and I said back in #4868, there's something odd about removing such a specific sync API (SslStream.AuthenticateAsClient) for such a general ""sync I/O is bad"" argument, without touching any other sync API. In other words, I'd expect either all sync APIs to stay for backwards compatibility or for a more sweeping removal of sync I/O APIs.

The request is made using an `HttpClient` taking an `HttpClientHandler` with `UseDefaultCredentials` set to `false`. On desktop CLR, we only see one HTTP request/response pair in the network: ![image](https://cloud.githubusercontent.com/assets/924164/11881634/cc350af6-a4bc-11e5-83b4-9be7f4bc9861.png) Which is expected for the test to pass.

The solution would be to create another overload of `Enumerable.Repeat` that is either parameterless or ones that accepts `Func` or `Func` that uses as a factory of the generated element, where the latter overload (with the `int` argument provides the index of the current element to be generated. ``` //will initialize an array of 40 instantiated StringBuilder objects. var builders = Enumerable.Repeat(40).ToArray(); //will initialize an array of 40 instantiated StringBuilder objects using a custom constructor var builders = Enumerable.Repeat(i => new StringBuilder($""Line {i} says:"")); ``` Another overload I'd want to see is for `Enumberable.Range`, is omitting the `start` parameter so that it's set to `0`, and only the `count` is provided.

" 5079 area-System.Text Proposal: System.Text.RegularExpressions.RegexRunner to become a public type Today the RegexRunner class is internal in CoreFX, because the Regex.CompileToAssembly functionality (the historically main entry point) that generates code inheriting from this class is not available in CoreFX. The CompileToAssembly API is not the only way to create such assemblies though, one could write code that inherits from this class and all the functionality required by RegexRunner to function properly is available in CoreFX and is used by other internal classes. The proposal is to make the RegexRunner class public, allowing scenarios where people are willing to generate code using a tool other than Regex.CompileToAssembly that targets CoreFX to be able to do so. In fact, it is also entirely possible that a developer could use Regex.CompileToAssembly in a build step (where they may have access to the full framework) and generate an assembly that initially (i.e. the output of CompileToAssembly) compiles against mscorlib, but further processing could result in the assembly being compiled against the System.Runtime contract assemblies. This brings a well-tested Regex interpreter implementation, the same one that is used in all other scenarios except precompilation to this scenario as well. The precompilation scenario is compelling (to us) for working set and startup performance reasons. 5080 area-System.Net CurlHandler fix for cookie handling CurlHandler has been handling cookies only from the final HTTP response.

In these tests used `TimeZoneInfo.Local.BaseUtcOffset.TotalMinutes` which is not right. Offset _can_ change.

Make 2 PR (the first - small roll back fix, the second - new tests with `[Theory]` attribute) 2. Make only full PR (but it will take some time for me) Small rollback PR I can do ASAP And how can we prevent accidental changes like https://github.com/dotnet/corefx/commit/3f91ae10 " 5130 area-System.Collections System.Collections.Generic: HashSet constructor throwing when passed another HashSet The constructor for HashSet that takes an IEnumerable is throwing an unexpected exception when passed another HashSet. repro test added to System.Collections test proj: ``` [Fact] public void CopyConstructor() { HashSet set = new HashSet(); HashSet set2 = new HashSet(set); // throws NullReferenceException } ``` Stack trace: ``` System.Collections.Tests.HashSet_Generic_Tests_int.CopyConstructor [FAIL] System.NullReferenceException : Object reference not set to an instance of an object.

As such the faster path offered to `EqualityComparer.Default` by implementing `IEquatable` is worth obtaining. Doing so would also remove the logical error identified in #5118, and although the path with this error (throwing on comparison with other instance of another type) is unreachable, that's worth doing. 5138 area-System.Net Implement IEquatable in CredentialKey and CredentialHostKey Improve performance of these types uses as dictionary keys, which is their intended purpose.

This is the only place in all of corefx (outside of the X509Certificates tests) that instantiates an X509Certificate object (instead of an X509Certificate2). Since the property still return an X509Certificate(1), the callers would have to cast it to use the X509Certificate2-only properties, but now an `as` will suffice, whereas before it required an up-converting operation. This should alleviate the user concern from #4510. cc: @CIPop @davidsh 5141 area-System.Collections HashSet constructor perf optimization concern #4349 added an optimization to `HashSet`'s constructor when constructing from another `HashSet` with the same comparer, by cloning the other `HashSet`'s fields: ``` c# public HashSet(IEnumerable collection, IEqualityComparer comparer) : this(comparer) { ... var otherAsHashSet = collection as HashSet; if (otherAsHashSet != null && AreEqualityComparersEqual(this, otherAsHashSet)) { ... _buckets = (int[])otherAsHashSet._buckets.Clone(); _slots = (Slot[])otherAsHashSet._slots.Clone(); _count = otherAsHashSet._count; ... } .... } ``` The upside to this optimization is it's fast, but there's a downside that I haven't seen discussed: If the other set had a large number of items at one point, and was subsequently reduced in size, the new set is going to simply clone the `_buckets` and `_slots` arrays, which means the new set could be creating new arrays that are substantially larger than they need to be. For example: ``` c# var source = new HashSet(Enumerable.Range(1, 8950)); source.Clear(); source.UnionWith(Enumerable.Range(1, 20)); var destination = new HashSet(source); ``` Behavior before the #4349 optimization: - `source._buckets` and `source._slots` are of length 17,519. - `destination._buckets` and `destination._slots` are of length 23. Behavior after the #4349 optimization: - `source._buckets` and `source._slots` are of length 17,519. - `destination._buckets` and `destination._slots` are of length 17,519. A workaround would be to call `source.TrimExcess()` before using it to construct a new `HashSet`, or calling `destination.TrimExcess()` after constructing, but that won't help existing code and using `TrimExcess()` is going to result in more array allocations. It'd be nice if the optimized path didn't blindly clone potentially unnecessarily huge arrays for `_buckets` and `_slots` when smaller array sizes would be sufficient for the destination. Does anyone else share this concern? An alternative optimization might look something like: ``` c# var otherAsHashSet = collection as HashSet; if (otherAsHashSet != null && AreEqualityComparersEqual(this, otherAsHashSet)) { Initialize(otherAsHashSet.Count); int lastIndex = otherAsHashSet._lastIndex; Slot[] slots = otherAsHashSet._slots; for (int i = 0; i < lastIndex; i++) { if (slots[i].hashCode >= 0) { AddIfNotPresent(slots[i].hashCode, slots[i].value) } } } ``` Where `AddIfNotPresent` has a new overload that supports taking a pre-calculated hashcode. This entire alternative optimization could also be moved inside `UnionWith`, which would simplify the constructor and optimize `UnionWith`. cc: @tpetrina @stephentoub @ellismg @ianhays @JonHanna 5144 area-System.Net System.Net Logging Tracking Items Tracking Items for https://github.com/dotnet/corefx/pull/5101 Formatting in *EventSource classes: - [ ] Make constants have PascalCasing. - [ ] Correctly separate arguments of methods in different lines (when needed). - [ ] Add spaces needed in the attributes of the methods when not correctly aligned. - [ ] New lines after if/else blocks (mainly after the IsEnabled check).

If a `HashSet` is constructed from an existing `HashSet` then use the current approach if the count is above a particular ratio to the capacity, but if it is below that ratio (small enough that if created just from those items and then added to the next resize would still not reach that capacity) use an optimised version of `AddIfNotPresent` to add each item. Fixes #5141 @justinvp this combines your suggestion about an optimised version of `AddIfNotPresent` with mine of using the current approach above a certain threshold of count/capacity. I took that threshold as being `ExpandPrime(count + 1)` though there's no perfect value (the best value would depend on what additions where later done, and how long the produced set would be kept in memory, so it can't be perfectly deduced). Done on top of the two commits for #5131 rather than repeat things that need to be included in this. I pretty much ignored the idea of optimising `UnionWith`. That certainly could be done along the same lines, but the `AddValue` I have here couldn't be quite as tightly optimised, with the skip on tests for the item being present and the skips on incrementing the count and version having to be undone. At the very least this needs more tests before I take off the WIP tag.

The docs for [the comparer constructor](https://msdn.microsoft.com/en-us/library/dd395024%28v=vs.110%29.aspx) state that a null comparer should throw an ArgumentNullException. However, the code actually performs a check on the comparer if it is null and sets it to the default comparer if it is. The docs for [the enumerable and comparer constructor](https://msdn.microsoft.com/en-us/library/dd394885%28v=vs.110%29.aspx) neglect to mention any behavior for when the comparer is null. The code will throw a NullReferenceException on [line 148 of SortedSet.cs](https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/Generic/SortedSet.cs) when it attempts to call `Compare` on the null Comparer that was passed as input. Suggested Solution: Behavior for null Comparers should be consistent across constructors.

I realize that could have a lot of implications, so the minimal request is exposing the denormal/subnormal flush mode, so that ""flush to zero"" can be enabled on IEEE float values. The scenario is that for certain real-time signal processing applications denormal numbers can pose performance problems. For a concrete scenario, consider the case of a real-time music synthesis program which provides various audio channels which have various audio processors operating on them. There is a class of audio processors, including delay/reverb type effects, which are implemented as IIR (infinite impulse response) filters. The character of these filters is that, when the input goes to silence, the internal state (and output) of the filter exponentially decays towards zero over time. The trouble arises if non-silent input occurs sporadically, which significant periods of silence between. In that case, it is possible for the internal state of the filter to decay to denormal float range. This usually causes a 1-2 order of magnitude cost increase in computation time, which often causes the synthesizer to glitch because it starts missing it's deadlines to provide buffers to the audio output device. The classic ""C"" solution is to enable ""flush-to-zero"" mode on the fpu, which solves the problem without code changes. The denormal threshhold is so far below audible that there is no loss of correctness for audio applications. In managed code, one could write code to detect the denormal bit pattern and flush to zero explicitly, but this comes at a performance cost, which is a pity especially since the hardware can do it for free. The reason it could be difficult is the question of how this would interoperate with other floating point consumers in the managed realm, such as WPF/winforms graphics libraries, as well as interop with unmanaged users of floating point. In general, modifying the fpu control register is very expensive (basically purges the entire processor pipeline), so it's to be done only infrequently. But correctness of other packages potentially could rely on IEEE denormal behavior. At minimum there could be a significant test impact. One mitigation could be that this option would be set on a per-thread basis, once, at thread initialization, much like the COM apartment model specification is done. That would fit well with the music synthesis world of this specific scenario, where dedicated threads are used to do the real-time work.

Although part of the draw of this library is access to high-performance vector math without resorting to native or unsafe code, there’s a lot of reasons you might have your data stored somewhere outside of a managed array. It’s not reasonable to copy all of your data into an array just to do vector operations on it, and then copy it back to its original location. Additionally, you might want to construct a one-off vector from the stack (perhaps using `stackalloc`), without having to make an entire array for the purpose of a single vector. Even if you have a safe `IntPtr` to your storage location, you cannot currently construct a `Vector` from it. We should expose better support for, at the very least, constructing `Vector`’s from arbitrary pointers, and storing them back into arbitrary locations. # Proposed API ``` CSharp public struct Vector { public Vector(void* dataPointer); public Vector(void* dataPointer, int offset); public Vector(IntPtr dataPointer); public Vector(IntPtr dataPointer, int offset); public void CopyTo(void* destination); public void CopyTo(void* destination, offset); public void CopyTo(IntPtr destination); public void CopyTo(IntPtr destination, offset); } ``` Because all pointer types can be implicitly converted to a `void*` pointer, you can use the first overloads above to load a `Vector` by passing a `float*` for example. It also allows you to load a `Vector` with any other pointer type, but in my opinion this is not a problem. Even with the alternate approach below (see “Alternative Approaches”), you can simply cast a pointer type to another and construct any kind of `Vector` you would like. This is desirable in some situations if you want to perform different calculations or reinterpret your data in some way. ## Constructor This behaves exactly the same way as the constructor taking an array, and allows an optional offset to be given in order to skip elements at the beginning of your storage. ## CopyTo This behaves exactly the same way as `CopyTo(T[])`, also with an optional offset to control the storage location. # JIT Recognition These new overloads must be recognized by the JIT. Functionally, they are pretty much identical to the existing overloads which operate on arrays. # Alternative Approach Instead of a “universal” pointer constructor, we could expose some “factory” methods which take a specifically-typed pointer and return a specifically typed `Vector`. ``` CSharp public static Vector Load(byte* dataPointer, int offset); public static Vector Load(int* dataPointer, int offset); public static Vector Load(float* dataPointer, int offset); ... ``` I don’t personally favor this approach as using static methods for construction doesn’t necessarily mesh with the existing usage patterns, and it also just adds a lot more methods than constructors (two per primitive type, so 20 in total). Also, It would still make sense to add the `IntPtr` constructor even if we went this route. Related to https://github.com/dotnet/corefx/issues/5106, https://github.com/dotnet/corefx/issues/3741 I have part of the additions (`void*` overloads) implemented in [this branch](https://github.com/mellinoe/corefx/commit/b7c5db276ac89dd599d9d088d0a467482ca340e8) with tests added. # Clarifications ### Q: Since `Vector` is a struct, why do we need special constructors for pointers pointers? Other BCL structures don't need special constructors for this, you can just cast, de-reference, etc. Because `Vector` is a generic struct, you can't directly take it's address, nor have a pointer to it. ``` error CS0208: Cannot take the address of, get the size of, or declare a pointer to a managed type ('Vector') ``` Consider `Vector4`, which is sort of similar to `Vector`. If you want to get a `Vector4` from a `float*` or vice-versa, you can just do the following, and you don't need a specialized constructor for it: ``` CSharp float* data = stackalloc float[4]; Vector4 vec = *(Vector4*)data; Vector4* vectorData = stackalloc Vector4[100]; Vector4 first = vectorData[0]; float* xPtr = &first.X; // etc. ``` Because `Vector` is generic, the above mechanisms aren't applicable and you're much more limited in how you can constructor and store them with pointers. 5203 area-System.ComponentModel Fix CustomValidationAttribute to properly implement RequiresValidatonContext Squashed replacement for https://github.com/dotnet/corefx/pull/3794 5204 area-Infrastructure corefx code coverage runs are consistently failing in CI "Some are failing with errors like this in the log: ``` 12:13:13 An exception occured: Failed to register(user:True,register:True,is64:False):5 the profiler assembly; you may want to look into permissions or using the -register:user option instead.

" 5205 area-System.Runtime API review: During shutdown, revisit finalization and provide a way to clean up resources "Running finalizers on reachable objects during shutdown is currently unreliable. This is a proposal to fix that and provide a way to clean up resources on shutdown in a reliable way. ## Issues observed on shutdown Currently, a best-effort attempt is made to run finalizers for all finalizable objects during shutdown, including reachable objects. Running finalizers for reachable objects is not reliable, as the objects are in an undefined state. - In order to finalize reachable objects, threads must be blocked, since objects that are still reachable cannot be used during or after finalization. Later, threads are terminated without running any more user code. - Running user code in finalizers after blocking other threads is unreliable, as those threads may be blocked at an inopportune point, and may cause finalizers to block indefinitely or result in undefined behavior due to the undefined state of the object - Example from a user code perspective. Consider an object that writes to a network stream using some stateful communication protocol. The finalizer would write a termination value to the stream and close the stream. Suppose that the termination value indicates to the receiving end that all data has been written, while abruptly closing the stream without writing the termination value would indicate incomplete transmission due to disconnection or some other reason. Writing the termination value in the finalizer assumes that there are no more references to the object, indicating that all data has been written. Suppose that a background thread is using the object, writing data to the pipe. During shutdown, the background thread is blocked at some arbitrary point, and the object is still referenced. Writing the termination value to the pipe in the finalizer at that point may be invalid according to the protocol. - Example from a runtime perspective. If a thread is blocked during GC, and a finalizer tries to allocate something, it may block waiting for GC to complete, which will never happen. The finalizer itself may not even allocate anything, but even just jitting the finalizer method will trigger allocation. While this particular issue can be fixed separately, it demonstrates the unreliability of the current design not just from a user code perspective but from a runtime perspective. - Effectively, the best-effort attempt to run finalizers for reachable finalizable objects is not reliable. ## Proposal - Don't run finalizers on shutdown (for reachable or unreachable objects) - Don't block threads on shutdown - Don't do a GC on shutdown (no change from current behavior) - Under this proposal, it is not guaranteed that all finalizable objects will be finalized before shutdown. - Doing a GC on shutdown and running finalizers for unreachable objects can guarantee that objects that are deterministically unreachable by the time of shutdown will be finalized. However, such objects should also be deterministically disposed before shutdown. For cases that require this, the user can trigger a GC explicitly and wait for finalizers before shutdown. - When there are background threads that are still running, there would be no guarantee on how many objects will be finalized anyway - Provide a public AssemblyLoadContext.Unloading event - An AssemblyLoadContext manages the lifetime of assemblies loaded under that context - Code should register for the event in the AssemblyLoadContext instance associated with the assembly - The event is raised when the GC determines that the AssemblyLoadContext instance is no longer referenced. For the default AssemblyLoadContext instance and for a custom instance installed as the default load context, the event will be raised before normal shutdown. - Abrupt shutdown due to unhandled exception, process kill, etc., will not raise any further Unloading events - As unloading an AssemblyLoadContext is not yet implemented, instances that have been used to load assemblies will currently live until the end of the process - No timeout. The timeout on waiting for finalizers to complete on shutdown was removed in CoreCLR some time back. In favor of treating blocking issues as program errors, no timeout will be used for this event either. - Event handler exceptions will crash the process. Any exception propagating out of an event handler will be treated as an unhandled exception. - Since other threads are not blocked before this, and may continue to run for a short period after the event is raised, event handlers may need to handle concurrency, and safeguard from using cleaned up resources from other threads ### Behavioral change ``` c# public static void Main() { var obj = new MyFinalizable(); } private class MyFinalizable { ~MyFinalizable() { Console.WriteLine(""~MyFinalizable""); } } ``` Previous output: ~MyFinalizable Typical output with the proposal above (running the finalizer is not guaranteed, but may run if a GC is triggered): (empty) ## Proposed API ``` c# namespace System.Runtime.Loader { public abstract class AssemblyLoadContext { public event Action Unloading; } } ``` ### Example ``` c# public class Logger { private static readonly object s_lock = new object(); private static bool s_isClosed = false; static Logger() { var currentAssembly = typeof(Loader).GetTypeInfo().Assembly; AssemblyLoadContext.GetLoadContext(currentAssembly).Unloading += OnAssemblyLoadContextUnloading; // Create log file based on configuration } private static void OnAssemblyLoadContextUnloading(AssemblyLoadContext sender) { // This may be called concurrently with WriteLine Close(); } private static void Close() { lock (s_lock) { if (s_isClosed) return; s_isClosed = true; // Write remaining in-memory log messages to log file and close log file } } public static void WriteLine(string message) { lock (s_lock) { if (s_isClosed) return; // Save log message in memory, if buffer is full, write messages to log file } } } ``` " 5206 area-Serialization XmlDictionaryReader removing significant whitespace "Using XmlDictionaryReader wrapped in a XmlReader to parse element with white spaces results in the white spaces being skipped.

Unfortunately it does that on the entire response file we generate to pass to vbc.exe. The define constants have quotation marks in them that need to be escaped, so we initially start with something like ``` -define: ""CONFIG=\""Debug\"" ``` which gets normalized to ``` -define: ""CONFIG=/""Debug/"" ``` which is no longer valid, and causes vbc.exe to error out.

"Currently any expression will compare with `void` with `TypeIs` as `false`: ``` C# Expression.Lambda>( Expression.TypeIs(Expression.Empty(), typeof(void)) ).Compile()() // false ``` This is at odds with `TypeEqual`: ``` C# Expression.Lambda>( Expression.TypeEqual(Expression.Empty(), typeof(void)) ).Compile()() // true ``` The decision happens at `AnalyzeTypeIs()` which is commented as saying: ``` C# // Oddly, we allow void operands // This is LinqV1 behavior of TypeIs ``` Arguably, its not that odd to allow void operands, considering that expressions of void type are allowed, or more reasonaly that dynamic use could mean passing something an expression of type `void` one time and a different type another. This also makes it a logical exception to the comment saying the result should match the result of `isinst` since there's no way to pass a void expression's value to in CIL (obviously enough as it doesn't have one). The differences between expression trees and CIL (and C#, VB.NET, etc.) are such that what is meaningless in CIL is meaningful, though constant, in trees. As such it seems to me that the value of `Expression.TypeIs(Expression.Empty(), typeof(void))` should be true, rather than false. In the other direction, we allow `Expression.TypeIs(Expression.Constant(""hello""), typeof(void))` but: ``` C# Expression.Lambda>(Expression.TypeIs(Expression.Constant(""hello""), typeof(void))).Compile()() ``` Throws `InvalidProgramException`. By the same reasoning as above it would make sense for this to return false.

This would seem to be a common-enough need, especially as .NET Core begins to be used outside of web apps. One complication as to why this is non-trivial is that the environment variable to this location is different on different OS's. Developers should not need to be aware of this just to get a home directory. It seems like there is some code to do this internally and it's even more complicated than I initially thought: https://github.com/dotnet/corefx/blob/d8508b20caa5fe523f1552cde174cb9ba5c31730/src/Common/src/System/IO/PersistedFiles.Unix.cs#L100 I wouldn't expect anyone to get that right if they had to do that on their own.

Etc. Should we have an API that accepts a NamedCurve and returns it as an explicit one? Or should that be a tuning parameter on Export? Do we need public API to describe the limitations of an implementation? (Windows doesn't do Char-2 curves, etc). Do we want to allow an explicit curve to be mapped back to a named one?

Traditionally, it's been a point of extensibility in our system for enabling serialization of your types to and from strings in query string and form data. We also rely on the built in converters for commonly used built-in types like `DateTime`. On CoreCLR the lookup of a `TypeConverter` is doing a bunch of attribute work up and down the inheritance hierarchy before falling back to a lookup table. On Desktop CLR this is cached in the common case. The performance effect on MVC of all of this attribute lookup is quite large. This is sampling data from an app doing model binding on 3 fields and then displaying them in an HTML form. Two of these fields use `TypeConverter` as shown here in the profile. Percentages here reflect % of CPU time inside of routing/MVC: ![image](https://cloud.githubusercontent.com/assets/1430011/12270760/8902d09c-b90c-11e5-84f3-749c02cc57a6.png) **Is this something we could work to address inside CoreFx?** **Or should we implement our own cache?** This is caching we've never had a need to do on Desktop. 5339 area-System.Console CancelKeyPress not firing on coreclr on ubuntu "Code: ``` using System; using System.IO; namespace HelloMvc { public class Program { public static void Main(string[] args) { System.Console.CancelKeyPress += (s,e) => System.Console.WriteLine(""BBB""); Console.ReadLine(); } } } ``` project.json: ``` { ""version"": ""1.0.1-*"", ""compilationOptions"": { ""emitEntryPoint"": true }, ""dependencies"" : { ""NETStandard.Library"": ""1.0.0-*"" }, ""frameworks"": { ""dnxcore50"": { } } } ``` Steps: 1.

When constructing a vector, we either accept the value coming from an array or a raw pointer. However, the number of elements being read is always `Vector.Length`. In many cases, the number of inputs to be processed is extrinsically defined and might not be a multiplier of `Vector.Length`, i.e. it's likely that there is a remainder. It might be beneficial to support constructing a vector and if there are fewer values than `Vector.Length` we pad with, for instance, zeroes. @mellinoe @CarolEidt 5362 area-Serialization Add support for XmlElement for data contract serializers This change is porting the support for XmlElement from Desktop implementation to data contract serializers. @shmao @SGuyGe @zhenlan 5364 area-System.Threading AggregateException should report better error messages A common issue when not using await is the print out ex.Message or ex.ToString() In the case of `AggregateException` and perhaps also `TargetInvocationException` these messages are kinda useless: `One or more errors occurred.` it would be nice to print out a more detailed message by default: 1. Print out how many error where found. 2. Print out the actual inner exceptions 5373 area-System.Net Disable failing NegotiateStream test #5284, #5326 cc: @davidsh, @cipop 5374 area-System.Net Throw SocketException rather than PNSE for unsupported socket option on Unix Match Windows exception type when an unsupported socket option is provided. cc: @davidsh, @ericeil, @cipop, @pgavlin Fixes https://github.com/dotnet/corefx/issues/4897 5377 area-System.Reflection Consider adding TypeDefinition.IsNested { get; } I'm testing https://github.com/dotnet/corefx/pull/4809/files. DisassemblingTypeProvider, the sample implementation used for tests, calls TypeDefinition.Attributes.IsNested in GetTypeFromDefinition, which can't be done outside Roslyn. I'm guessing we'll want everything the reference implementation does be possible for public consumers to do. 5378 area-System.Diagnostics Process.Start() sometimes returns wrong ProcessName "If executing following code with NETStandard.Library of 1.0.0-rc2-23712: using System; using System.Diagnostics; namespace ConsoleApplication { public class Program { public static void Main(string[] args) { for (int i=0; i<100; i++) { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = ""ping""; startInfo.Arguments = ""localhost -c 1""; ``` Process process = new Process(); process.StartInfo = startInfo; process.Start(); Console.WriteLine(""processName is: {0}"", process.ProcessName); } } } ``` } You will see that output ProcessName is usually correct (""ping"") the first time, but usually incorrect in subsequent iterations. If one extends the life of command (change argument to something like ""-c 3""), wait a second or so, and then do a ""GetProcessById"", you would see that the ProcessName has become correct. This indicates a race condition of some sort.

area-System.Net SslStream ReadAsync/WriteAsync end up Sync Symptom: https://github.com/aspnet/KestrelHttpServer/issues/569 `SslStream` doesn't override `Stream`'s `ReadAsync`/`WriteAsync` methods which means they call the default implementation which is a wrapper on `Stream`'s `BeginRead` and `EndRead` etc. `BeginRead` eventually ends up calling the underlying stream's synchronous `Read` method. If the stream it wraps is completely async; then its sync read may wait on a `.GetAwaiter().GetResult()` of its async read/write. At which point you have Async->Sync->Async.Wait() and things go bad... First guess would be `SslStream` should additionally override ``` csharp public override Task ReadAsync(byte[] buffer, int offset, int count, CancellationToken cancellationToken) { return _sslState.SecureStream.ReadAsync(buffer, offset, count, cancellationToken); } public override Task WriteAsync(byte[] buffer, int offset, int count, CancellationToken token) { return _sslState.SecureStream.WriteAsync(buffer, offset, count, token); } ``` but there may be more to it. 5491 area-System.Net SslStream override stream's async methods Rather than using Streams default implementation which end up calling the sync methods.

Data Point 2: System.Net.CredentialCache.DefaultCredentials is immutably set to a default SystemNetworkCredential (all empty strings for user, password, domain). Data Point 3: http://dotnet.github.io/getting-started/ Following the recommended steps to install .net core on Ubuntu Linux includes the step ""dotnet restore"" and exposes this failure whenever a simple proxy server is configured (e.g http_proxy=http://myserver.domain:8080/) DNX tools grab the default credendtials and the entire installation fails due to the exception in SetProxyOptions(). It's clear the intention is that the Curl library should detect the lack of credentials and not attempt to use them. Presently it only succeeds if creds are null, but not when username is an empty string as in the case of the default creds used by DNX tools. Conclusion: Fundamentally this is an incompatibility between the three implementations: DNX tools, the CurlHandler.SetproxyOptions() and DefaultCredentials. One of the three needs to be changed so that the three are compatible with one another. Arguably the DNX tools or the default credentials could be faulted, but SetProxyOptions seems the friendliest change to the contract between these three components because other clients might similarly use default empty credentials in the case where none are specified or present.

" 5551 area-System.Net Several System.Net.Security fixes "1. Windows and Unix. The ProcessAuthentication method sets a flag to indicate that an operation is in progress, then kicks off the operation, and then in a finally block potentially resets the flag. The intent of resetting it is to reset the flag iff the operation is no longer in progress, which would be the case if the operation was synchronous or if the initiation of the asynchronous operation resulted in an exception. As such, the finally block is checking whether the operation was synchronous or whether an exception has been captured. However, for the exceptional case, this leads to race conditions. The initiation of the asynchronous operaiton can lead to the operation running concurrently with the remainder of the ProcessAuthentication method, namely concurrently with the finally block. If the operation starts quickly and fails quickly, it'll store the exception, which will cause the finally block to see that an exception has been captured and mistakenly believe that the operation failed synchronously, thus resetting the flag. But the operation was actually asynchronous, and when EndAuthentication is called, it'll see that the flag has been reset and think that the EndAuthentication call is erroneous, thus throwing an exception. While it should throw an exception (the one that caused the operation to fail), it ends up throwing an InvalidOperationException instead to signal that EndAuthentication was used incorrectly. The fix is to move the check for the exceptional situation out of the finally and into a catch block. The catch block is then used to reset the flag only if an exception emerges synchronously, and the finally block is used to reset the flag only for synchronous operations. (It's possible that for synchronous operations that fail, the flag could be written as 0 twice... that's fine.) This fixes the failure on both Windows and Unix. The failure wasn't reproing on Windows but only because of differences in timing... adding a brief pause at the end of the try block would trigger the failure on Windows as well. 2. Unix. The design of AuthenticateAsServerAsync has a clientCertificatesRequired flag. On Unix we were mapping that to ""SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT"", which causes OpenSSL to fail the handshake if no cert is provided. But the Windows code actually still allows this through, instead setting a policy error to indicate that no certificate was required. I'm simply removing the SSL_VERIFY_FAIL_IF_NO_PEER_CERT flag to match that design. I've also updated the test to assert that the error is actually being set. 3. Unix. When SSL failures occur, there are multiple places to check for errors. One starts with SSL errors, then potentially examines general crypto errors, and then potentially examines errno values. Our code wasn't properly handling this, and even for situations where it was, it was potentially conflating all of the values together as the first category, making it more difficult to interpret and tell them apart. This updates the code to capture the appropriate exception information. There are still some issues around properly mapping and roundtripping error values between the Unix PAL implementation and the consuming shared code, but this at least makes it easier for a developer of the library to debug issues. 4. Linux. All of the System.Net.Security tests were disabled on Unix. I've re-enabled them on Linux now that the causes for the failures have been fixed. I've not yet verified the fixes on OS X, so I've left them disabled there for now. cc: @bartonjs, @ericeil, @cipop, @davidsh, @vijaykota Fixes https://github.com/dotnet/corefx/issues/4317, https://github.com/dotnet/corefx/issues/4606 " 5552 area-System.Runtime Add string.Join(char, ...) overloads "Moved from https://github.com/dotnet/coreclr/issues/2736#issuecomment-173295835 on behalf of @jasonwilliams200OK Current situation: ``` c# char separator = ':'; string joined = string.Join(separator.ToString(), ""one"", ""two"", ""three""); ``` With `char` overload, users will be able to join string without calling `ToString()` i.e. `string joined = string.Join(separator, ""one"", ""two"", ""three"");` This will reduce at least one string allocation per call: https://github.com/dotnet/coreclr/blob/80c2952/src/mscorlib/src/System/Char.cs#L145-L168. # Proposed API surface -

By default, they serve XML responses, and JSON when requested using `Content-Type` header. Despite calling `request.ContentType = ""application/json"";` the UWP App incorrectly makes a request without the desired `Content-Type` header. The same code works fine in regular windows Console Application. Furthermore, running the culprit method from a regular Win32 process (by loading the assembly via AppDomain) correctly sets `Content-Type`, which makes me assume that the problem lies within the UWP runtime.

This kind of re-throwing ends up clobbering the original call stack and Watson bucket stored in the Exception, making it more difficult for someone looking at the exception to understand where it came from. To address this, ExceptionDispatchInfo was added in .NET 4.5, and is now used in places like Task that have this exact issue. I'd suggest we look at using ExceptionDispatchInfo in all of these places. Basically, instead of just storing an Exception, you'd store the result of ExceptionDispatchInfo.Capture(caughtException), and then instead of using throw _caughtException;, you'd do _caughtExceptionDispatchInfo.Throw();. ExceptionDispatchInfo will preserve the original information and append the new throw location's call stack rather than using it to overwrite the original.

By default, if an MRES isn't yet Set when it's waited on, MRES.Wait() does a bit of spinning before falling back to a true blocking wait. But in this situation, we expect that either the socket operation will complete synchronously or will take some non-trivial amount of time to complete asynchronously, in which case the spinning is generally unnecessary overhead. This commit simply disables that extra spinning. cc: @pgavlin, @ericeil, @vancem (Assuming https://github.com/dotnet/corefx/pull/5472 gets checked in after the issues it's facing are fixed, this change will still matter but only in the situation where sync and async calls are mixed on the same Socket instance, such that the socket is put into non-blocking mode and we hit these code paths.) 5657 area-System.Data RC2 - A connection was successfully established with the server, but then an error occurred during the pre-login handshake "Platform : Linux Ubuntu Runtime : 1.0.0-rc2-16357,coreclr,x64,linux System.Data.SqlClient : 4.0.0-rc2-23623 ConnectionString : Data Source=XXXXXXXX,60606;Initial Catalog=XXXXXXXX;Integrated Security=False;User ID=sa;Password=XXXX;Connect Timeout=10;Encrypt=False;Application Name=""vNEXT"" Works perfectly on Windows using same runtime as above.

_This issue exists on Linux only_ When establishing a connection to a TCP server where a client certificate is required, the client certificate does not get passed to the server side. The connection then gets aborted by the server, resulting in an exception as below. Using NetMon, we can observe during that handshake that the server successfully sends its certificate to the client, but the client never presents the client certificate to the server. At this point, the server will send an RST and the connection is killed. I've isolated the repro to using just a TcpClient and TcpServer + SslStream - see https://gist.github.com/iamjasonp/27cd1ebce287f8b51d0e for the rudimentary repro. Platforms tested - .NET Desktop - :white_check_mark: - .NET Core - Windows: :white_check_mark: - .NET Core - Linux: :x: First chance exception caught: ``` 'System.Security.Authentication.AuthenticationException' in System.dll Additional information: The remote certificate is invalid according to the validation procedure. ``` Server call stack: ``` System.dll!System.Net.Security.SslState.ForceAuthentication(bool receiveFirst, byte[] buffer, System.Net.AsyncProtocolRequest asyncRequest) System.dll!System.Net.Security.SslState.ProcessAuthentication(System.Net.LazyAsyncResult lazyResult) System.dll!System.Net.Security.SslStream.AuthenticateAsServer(System.Security.Cryptography.X509Certificates.X509Certificate serverCertificate, bool clientCertificateRequired, System.Security.Authentication.SslProtocols enabledSslProtocols, bool checkCertificateRevocation) TcpRepro-Server.exe!Examples.System.Net.SslTcpServer.ProcessClient(System.Net.Sockets.TcpClient client) TcpRepro-Server.exe!Examples.System.Net.SslTcpServer.RunServer() TcpRepro-Server.exe!Examples.System.Net.SslTcpServer.Main(string[] args) ``` This also looks to be the root cause of the issue in https://github.com/dotnet/wcf/issues/619#issuecomment-173177433 5671 area-System.IO Add Canterbury Corpus perf tests to Compression Our System.IO.Compression tests were using deterministically generated random data to test compression/decompression time.

I've started building out a little ORM project for .Net Core and noticed that the DbConnection did not have any interfaces that I can wrap my providers behind. Is this something in the roadmap? If not, what is the expectation for unit testing, fakes by inheritance and what was the reasoning behind making this change from how .Net worked? Would this mean I have to build an abstraction layer over IDbConnection/DbConnection so I can support a .Net 4.5 implementation & a .Net Core implementation?

There doesn't appear to be a ""C"" api for the generic name. There is an ICU C++ api to get the 'generic' name. However, we can only use the ""C"" apis and not the C++ apis. See [Remove OSX Homebrew ICU dependency](https://github.com/dotnet/coreclr/pull/1851). I can think of 2 ways to fix this: 1. Use the C++ apis on platforms that allow it (not OSX) 2. Read the CLDR data directly. Some background from @mj1856, if we decide to take the second approach: part of the reason generic names are challenging is because there are three different patterns in the raw data. Examples of each: Pattern 1 – Generic name differs from both standard and daylight names: Generic Name: “Pacific Time” Standard Name: “Pacific Standard Time” Daylight Name: “Pacific Daylight Time” Pattern 2 – Generic name matches the standard name: Generic Name: “Central European Time” Standard Name: “Central European Time” Daylight Name: “Central European Summer Time” Pattern 3 – No generic name exists, so revert to the location based form: Generic Name: none, so use “UK Time” Standard Name: “Greenwich Mean Time” Daylight Name: “British Summer Time” I’m not sure exactly why, but I can confirm in these [docs](http://userguide.icu-project.org/datetime/timezone): > Generic name, such as ""Pacific Time"". Currently, this is not supported by ICU. Not sure why they chose not to implement, but might have something to do with the above. Also worth mentioning, CLDR Generic Name is not quite a one-to-one match with our idea of a Display Name. Consider that many build time zone pickers by iterating over all time zones given by TimeZoneInfo.GetSystemTimeZones, then putting them in a dropdown with Id for the value and DisplayName for the text shown to the user. This works because Display Names are unique within the results. It doesn’t quite work with Generic Name, as multiple different time zones will use the same Generic Name. For example, both Europe/Paris and Europe/Berlin will have “Central European Time” as their generic name, because they’re both in the same CLDR metazone. To build a picker for IANA zones that doesn’t actually show the Id to the user requires also asking the user for a country. If we use Generic Name as a Display Name, we might want to concatenate a country name or code, such as “Central European Time (France)” / “Central European Time (Germany)”. " 5743 area-Infrastructure Clean up build.sh and mono.targets Once we move to using .Net Core MSBuild for x-plat build, we should clean up build.sh script since it has a lot of code that downloaded msbuild plus it had some checks for prerequisites. We should also stop using mono.targets, since they shouldn't be required anymore. 5744 area-System.Reflection Allow reflection to identify substituted generic types "For overload resolution tie breakers Roslyn needs a way to differentiate between a substituted generic and actual type, e.g: ``` C# class Foo { void Bar(T v); void Bar(int v); } ``` Consider this code: ``` C# dynamic foo = new Foo(); foo.Bar(2); ``` Notice the use of `dynamic`. This forces the overload resolution to happen at runtime, with reflection being the provider for the type information the C# binder uses. The goal is to have overload resolution pick the second method, instead of failing. They currently use `MetadataToken` to compare the original definitions. Given this API throws in certain cases now (e.g. CoreRT), it would be better if we could introduce a new APIs. ### Repro ``` C# class Program { static void Main(string[] args) { dynamic foo = new Foo(); foo.Bar(2); } class Foo { public void Bar(T v) { System.Console.WriteLine(""generic""); } public void Bar(int v) { System.Console.WriteLine(""not generic""); } } } ``` - Works on .NET Framework and prints ""not generic"", - On .NET Core the behavior is not guaranteed. The late binder will try to get to `MetadataToken` through private reflection and use that, but if that fails - it is not there or throws -- it will will just pick one of the overloads at random. @VSadov @weshaggard @pallavit " 5745 area-System.Data Add Default Configuration Option in System.Data.Common.csproj The csproj should include a default Windows_Debug Configuration to prevent potential packaging issues on Windows 5749 area-System.Net Add a clean way to cancel a long-running Socket operation (e.g. accept or connect) The normal pattern to listen for incoming connections is: ```c# using (var s = new Socket(...)) { s.Bind(...); s.Listen(...); while (true) { var connectionSocket = s.Accept(); Task.Run(() => ProcessConnection(connectionSocket)); } } ``` The only way to reliably cancel that loop is to close the socket. This works, but it causes an `ObjectDisposedException` which is usually one of the reserved exception types that always indicate a bug such as `NRE` and `ArgumentNullException`. Catching that exception might hide real bugs. You might confuse the intended `ObjectDisposedException` with one that is not supposed to happen but did (bug). Also, this seems to be racy. What if the handle is closed right before `Accept` passes it to the native `accept` function? Is that even thread-safe?! Could be a use of an invalid/unintended handle. Note sure if the BCL has a way to prevent that scenario. Some people suggest to break the loop by connecting to that socket. That might not be possible depending on what interface you are listening on. There are no guarantees to be able to connect anywhere at all. Also, this feels like such a dirty hack. There are ideas of using `IAsyncResult.WaitHandle` with a timeout or in combination with another wait handle but that's quite nasty code and much slower than not using a wait handle. It's much faster to let the kernel wait as part of a synchronous call than to execute an asynchronous call, then create an event object, wait for it and then dispose of all of this. Also, in case you do a `WaitHandle.WaitAny(ioHandle, cancelHandle)` and you find yourself in the cancellation case you _still_ need to abort the IO using `Socket.Close` which is the same dirtiness. It does not matter for this issue whether you're using sync or async IO. Please add a way to cancel any long-running socket operation such as accept, connect, read, write, shutdown in a clean way. This could take the form of a `CancellationToken` or a method `Socket.AbortPendingOperations()`. A cancelled operation should throw an exception that allows to identify the situation so that it can be caught reliably. Cancelling is not just important for breaking the accept loop but it's useful for all other long-running operations as well. Sometimes you need to be able to shut down processing. 5750 area-System.Net SendRecvAsync_Stream_TCP test failed on OS X http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/osx_debug_tst/306/console ``` 09:48:08 Unhandled Exception: Xunit.Sdk.EqualException: Assert.Equal() Failure 09:48:08 Expected: Success 09:48:08 Actual: OperationAborted 09:48:08 at Xunit.Assert.Equal[T](T expected, T actual, IEqualityComparer`1 comparer) 09:48:08 at System.Net.Sockets.Tests.SocketAsyncExtensions.<>c__DisplayClass3_0.b__0(Object _, SocketAsyncEventArgs args) 09:48:08 at System.Net.Sockets.Tests.SocketAsyncExtensions.ReceiveAsync(Socket socket, SocketAsyncEventArgs eventArgs, IList`1 buffers, SocketFlags flags, Action`1 handler) 09:48:08 at System.Net.Sockets.Tests.SendReceive.<>c__DisplayClass4_3.b__2(Int32 received) 09:48:08 at System.Net.Sockets.Tests.SocketAsyncExtensions.<>c__DisplayClass3_0.b__0(Object _, SocketAsyncEventArgs args) 09:48:08 at System.Net.Sockets.SocketAsyncEventArgs.OnCompleted(SocketAsyncEventArgs e) 09:48:08 at System.Net.Sockets.SocketAsyncEventArgs.ExecutionCallback(Object state) 09:48:08 at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) 09:48:08 at System.Net.Sockets.SocketAsyncEventArgs.FinishOperationSuccess(SocketError socketError, Int32 bytesTransferred, SocketFlags flags) 09:48:08 at System.Net.Sockets.SocketAsyncEventArgs.CompletionCallback(Int32 bytesTransferred, SocketError socketError) 09:48:08 at System.Net.Sockets.SocketAsyncEventArgs.TransferCompletionCallback(Int32 bytesTransferred, Byte[] socketAddress, Int32 socketAddressSize, SocketFlags receivedFlags, SocketError socketError) 09:48:08 at System.Net.Sockets.SocketAsyncContext.<>c.b__42_0(Object args) 09:48:08 at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) 09:48:08 at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() 09:48:08 at System.Threading.ThreadPoolWorkQueue.Dispatch() ``` 5754 area-System.Net Linux workaround for multiple connect attempts per socket does not work "On Linux, we attempt to re-use a socket for multiple connection attempts by ""connecting"" the socket to an invalid address between each ""real"" connect attempt.

This does not work as intended. In the current implementation, the raw call to `connect()` cases any pending call to `epoll_wait()` to wake up and mark the socket as connected; any subsequent connect attempt on a non-blocking socket (or an Async connect attempt) then appears to succeed immediately, whether it did in fact or not. This is causing some tests (e.g., `System.Net.Sockets.Tests.DualMode.ConnectV4V6IPAddressListToV6Host_Success`) to appear to succeed, even though the connection is never successfully established. Once #5472 is merged, this test will hang, as the non-blocking connect will now be blocking, and this bug will no longer mask the underlying issue. I tried fixing this in the blocking case, by adding a call to `PrimeForNextConnectAttempt` after a blocking `connect` fails, and discovered that this also does not work. The subsequent connect attempt simply blocks until it times out. If I disable this feature entirely, forcing Socket methods that connect to address lists to use multiple sockets instead, then the test passes.

It's hard to maintain symmetry on that flow for the Unix pathway, due to the API differences in OpenSSL and SChannel. So, the Unix session will always pass down to native the provided client auth credentials, and OpenSSL can use them when it sees appropriate. 2) Untrusted certificates should still complete handshake The Unix SslStream implementation had two different places that a client authentication certificate was validated. The first one was from an OpenSSL callback, and reporting an error will interrupt the TLS handshake. The second was from after the handshake, and presents the results to the user validation callback to determine if data should be sent after the handshake. In the ideal case the first version is redundant, in a user-handled case it caused a failure when success was expected; so it should just be removed. 3) Enable the end-to-end client authentication cert test for Unix Also asserts that the IsMutuallyAuthenticated property gets set, the certificates used were the correct ones, and that both forward and callback versions of providing the certificate function.

We had attempted to do this on Linux, but it did not work (see #5754). `Socket` has multiple methods that depend on being able to try connections to multiple endpoints on a single socket: ``` csharp public void Connect(IPAddress[] addresses, int port) ``` ...attempts to connect to each of `addresses`, returning when one of them is successful. ``` csharp public void Connect(string host, int port) ``` ...does a DNS lookup, which may return multiple addresses, then attempts to connect to each of them until successful. ``` csharp public void Connect(EndPoint remoteEP) ``` If this is passed a `DnsEndPoint`, then this behaves the same as `Connect(string, int)`, trying all resolved addresses. Additionally, we support async variants of all of these. On Unix we currently ""fake"" this by creating multiple temporary sockets behind the scenes, trying to connect each of them to a different address. If one succeeds, we immediately disconnect it and connect the ""real"" socket to that address. This workaround has some possibly unacceptable implications: 1) Whichever endpoint we finally choose, we will end up connecting to it _twice_, once for the ""probe"" connection, to see if it will work, and again for the ""real"" connection. This will cause issues for servers that do not expect more than one connection, for load balancers that try to distribute connections, etc. It's also a lot of undesired network overhead. 2) Even though the first connection attempt succeeded, the second will not necessarily succeed. This is especially true in scenarios like DNS-based load balancing. So we have a functional issue here, where we may fail to connect the ""real"" socket in cases where we would have succeeded. I do not think we should leave this as-is, as it will create too many unexpected strange behaviors in code that uses these, expecting them to behave the same way as they do on Windows. So I propose doing one of the following: a) Remove the `Connect` overloads that take multiple endpoints, and the `DnsEndpoint` type, from the public contracts. -- or -- b) Change these Connect overloads to throw `PlatformNotSupportedException` on Unix, Also, change `Connect(EndPoint, int)` to throw `PlatformNotSupportedException` if passed a `DnsEndPoint`. In either case, we should provide sample code for how to code equivalent behavior using the remaining APIs. @stephentoub, @pgavlin, @CIPop, @davidsh, @SidharthNabar, please provide feedback.

Closing a socket does not cancel a blocking operation on Unix OSs. 5835 area-System.Net Override ReadByte on SslStream In an application that's using the Redis client library, a significant portion of the allocations are coming from calls to ReadByte on an SslStream. Since SslStream doesn't override ReadByte, the base Stream.ReadByte is used, and it ends up allocating a temporary array to use in a call to Read. This commit adds an override of ReadByte on SslStream that returns data from the stream's internal buffer if any is available, otherwise falling back to the old behavior. On a test that repeatedly writes 1000 bytes and then reads each of those with ReadByte, allocations are reduced by 10x and throughput is doubled. (Note that removing the Interlocked.Exchange in ReadByte yields another 20% improvement in throughput, but I've left it in so as not to impact guarantees of the type.) cc: @cipop, @davidsh, @vancem 5840 area-System.Data System.Data.ProviderBase.DbConnectionFactory.TryGetConnection() has a misleading comment for use of Sleep() "`System.Data.ProviderBase.DbConnectionFactory.TryGetConnection()` has these lines: ``` // Yield time slice to allow shut down activities to complete and a new, running pool to be instantiated // before retrying. Threading.Thread.Sleep(timeBetweenRetriesMilliseconds); timeBetweenRetriesMilliseconds *= 2; // double the wait time for next iteration ``` `timeBetweenRetriesMilliseconds` starts with a value of `1` and is doubled on each iteration. ""yield time slice"" is the idiom for passing zero into `Sleep()` to mean ""I don't want to wait for long, but if there's anyone else wanting CPU time then I'll let them have that time"". When any other value is passed that actual wait, not ""yielding time slice"".

In order to map the different HttpClientHandler properties to the WinHttpHandler properties, the HttpClientHandler .UseDefaultCredentials. needs to turn on/off two credentials related properties of WinHttpHandler, .ServerCredentials and .DefaultProxyCredentials.

Thank you in advance for any help. ### Long Story I'm working on a prototype using **Mac OSX** and **Visual Studio Code** with `dnxcore50` using `coreclr-rc1-update1` but I'm getting the runtime error when trying to send email using **MailKit** lib. @jstedfast, the lib developer said the lib was working perfectly fine when things ran on windows so the problem could be in **the CLR version** for non Windows environments. I setup a **Windows 10** VM to verify if the problem was indeed not present. The test was successful. No runtime error was thrown. I tried to deploy as an **Azure Web Site**, and after a few hours of troubleshooting trying to make **coreclr** and not **clr** the runtime target I finally got the app built. But the test failed with the same error I was getting in **Mac OSX** even though it was a Windows Environment! I made more research and found this: - In my local **Windows 10** when I built the project the **DNU** starting message was `Microsoft .NET Development Utility CoreClr-x64-1.0.0-rc1-16231` - In the **Azure** building log stream the **DNU** starting message was `Microsoft .NET Development Utility CoreClr-x64-1.0.0-rc1-16202` Looking at the `deploy.cmd` that I had previously modified to target **coreclr** and not **clr** I noticed that the targeted runtime was `dnx-coreclr-win-x64.1.0.0-rc1-final` In my **Windows 10** local the target runtime was `dnx-coreclr-win-x64.1.0.0-rc1-update1` So I changed the target runtime in `deploy.cmd` to `dnx-coreclr-win-x64.1.0.0-rc1-update1`, pushed to **Azure** and now in the building log stream the **DNU** starting message was `Microsoft .NET Development Utility CoreClr-x64-1.0.0-rc1-16231`, the same as my **Windows 10** local. I ran my test again and the error was gone!! After that I concluded that whatever the root cause of the exception I was getting, the problem appears to be fixed in `rc1-update1`, BUT... it turns out that in **OSX** the error is triggering even though the **DNU** starting message is `Microsoft .NET Development Utility CoreClr-x64-1.0.0-rc1-16231` when I build the project. So it makes me think it could be that the **OSX** version is not really `rc1-update1` **(CoreClr-x64-1.0.0-rc1-16231)** but `rc1-final` **(CoreClr-x64-1.0.0-rc1-16202)**. It's just a though as I don't know if it's possible or correct/normal that the same version on both platforms can have different features / fixes. That's why I'm submitting this issue. 5861 area-System.Data DbConnection and DbCommand should have a finaliser Originally `DbConnection` and `DbCommand` classes were derived from `System.ComponentModel.Component`. From that they inherited a finaliser that called `Dispose(false)`. Their descendants sometimes depend on this, in particular `SqlConnection` has finaliser-only code. They should have finalisers directly added. ~~`DbTransaction` and `DbDataReader` were never derived from `Component` but do both follow the `Dispose(bool)` pattern, as such suggesting that a finaliser exists which would call `Dispose(false)`. While not used within the corefx assemblies a third party derived class could erroneously depend on this.~~ ~~As such they should have finalisers added, and then suppressed in the existing derived classes.~~ (Moved this part to #5865) 5864 area-Infrastructure CI jobs failing with WS-CLEANUP errors Lots of legs failing with errors like this, e.g. http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/osx_release_bld_prtest/495/console ``` ERROR: [WS-CLEANUP] Cannot delete workspace: remote file operation failed: d:\j\workspace\dotnet_corefx\osx_release_bld_prtest at hudson.remoting.Channel@270f3ae7:dci-win-tbld-6: java.nio.file.AccessDeniedException: d:\j\workspace\dotnet_corefx\osx_release_bld_prtest\Tools\dotnetcli\bin\coreclr.dll ``` 5868 area-System.Diagnostics Debugger.NotifyOfCrossThreadDependency missing from System.Diagnostics.Debug contract NotifyOfCrossThreadDependency is used in code any time a debugger accessing that property would potentially cause deadlocks, race conditions, or other behavior changes, e.g. if the debugger has frozen all threads in the process (which it does at a breakpoint), and a property getting evaluated blocks waiting for another thread to perform some operation.

We need to clean this up, but before we do we need to a) look upstack in CoreFx and b) reach out to partner teams to find out if anyone is expecting support on 4.6.

MemberInfos differ only by ReflectedType (i.e. they are the same member, but one of them was obtained from a derived type.) ``` C# public class C { public int F; } public class D : C {} static class Program { static void Main(string[] args) { var f1 = typeof(C).GetField(""F""); var f2 = typeof(D).GetField(""F""); System.Console.WriteLine(f1.Equals(f2)); // False } } ``` ### 2. One MemberInfo is a generic instantiation of another. ``` C# static class Program { static void Main(string[] args) { var m1 = typeof(List<>).GetMethod(""Add""); var m2 = typeof(List).GetMethod(""Add""); // how to determine that m2 is instantiated from m1? } } ``` On platforms that support the MetadataToken, this can be worked around by comparing the tokens, but without them, one has to resort to error-prone comparisons of the declaring type, name, and signature. There should be a first-class portable way to address both. ### Proposal for New API: HasSameMetadataDefinitionAs Add a new API that determines if a member is backed/instantiated from the same metadata definition. In ECMA-335 terms, this is a member/type from the same module that has the same metadata def token. Platforms like .NET Native that do not keep around metadata tokens should still preserve enough information to answer this query portably. ``` C# public class MemberInfo { public virtual bool HasSameMetadataDefinitionAs(MemberInfo other); ... } ``` A mostly correct implementation is: ``` C# return Module.Equals(other.Module) && MetadataToken == other.MetadataToken; ``` But that ignores edge cases such as TypeInfo instances for array, byref, pointer, and type parameters types, which we'd need to spec and test. " 5886 area-System.Net Process and Ping should have finaliser In the wake of #5861 I decided to examine other classes in CoreFX that were originally derived from `Component` to see if there was a risk that classes derived from them in turn could depend upon their having a finaliser. The following need no action, but I list them in case someone can spot one I missed or a flaw in my reasoning that they are okay as-is: `ProcessThread`. No longer disposable, functionally sealed (can't be derived as there are no public or protected constructors). `ProcessModule`. No longer disposable, functionally sealed. `FileSystemWatcher`. Already has a finaliser. `PerformanceCounter`. ref only. This leaves `Process` and `Ping` as two classes that can be derived from, would originally have had a finalizer calling `Dispose(false)` via `Component`, and which do not currently have this. For compatibility with 4.6 and earlier they should have a finalizer. Further, `ProcessModule` no longer needs one, but still calls `SuppressFinalize` which should be removed as unnecessary. 5887 area-System.Net Add finalizers to Process and Ping Have them call `Dispose(false)`. `SuppressFinalize(this)` in constructors if they are not a derived type to lessen the possible negative impact on collection.

This differs from the compiler, which allows both. Possibly this should just be documented as a limitation. Possibly something could be done by manipulating `RuntimeWrappedException`. Possibly something could be done for catching, but not for throwing, which both seems easier on first blush, and may have more use (throwing such an object is a bad idea after all, catching one might be needed due to someone else's bad idea). cc: @VSadov @bartdesmet 5899 area-Meta Documentation Duplication Between .NET Projects As I'm working on #5877, I started thinking that between CoreCLR and CoreFX there's going to be lots of things that need to be explain in both contexts. The Terms section alone in [glossary](../Documentation/project-docs/glossary.md) would probably be useful for both projects. Would it make sense to move this kind of stuff to the [core-docs](https://github.com/dotnet/core-docs) repo? /CC: @terrajobst @jasonwilliams200OK 5902 area-System.Console echo TTY mode disabled for launched processes Similar to #5109, if `Console.ReadKey()` has been used by a .NET program, the `echo` TTY mode is disabled. To resolve the prior issues, dotnet/coreclr#2561 re-enabled the `echo` mode on program shutdown. However, we've run into a different scenario: launching a process from the .NET program inherits the TTY modes. So if you launch Bash from the .NET program, you can't type in it until you've explicitly re-enabled `echo`. 5907 area-System.Net Keep accepted sockets open until the tests are done with them. Prior to this change, a GC triggered at the wrong time could cause a newly-accepted Socket to be collected and finalized, closing the connection before the other end of the socket was done. To avoid this, we keep a reference to the new socket until the test is done with the connection.

As such the following is valid: ``` C# Expression.MakeTry( typeof(void), Expression.Throw(Expression.Constant(new InvalidOperationException()), typeof(int)), null, null, new[] { Expression.Catch(typeof(InvalidCastException), Expression.Constant(""hello"")), Expression.Catch(typeof(Exception), Expression.Constant(2.2)) } ) ``` This works fine with the compiler. With the interpreter it unbalances the stack, leaking a value and throwing several asserts in Debug.

The bug had been fixed on desktop. We should port the fix to .Net Core. 5915 area-System.Data API for retrieving Columns Metadata from DbDataReader # API for GetColumnSchema ## Problem DbDataReader on .Net Framework, provides an API called `DataTable GetSchemaTable()` which was returns the metadata of the columns being read using the DbDataReader object. Because of the removal of DataTable in .Net Core this API had to be removed. `DbDataReader.GetSchemaTable()` needs a replacement in .Net core. ## Progress The data structure DbColumn along with the necessary attributes which should be present for the various ADO.Net providers to effectively provide the metadata for the columns is provided in the issue. ``` C# namespace System.Data.Common { // DbColumn contains the base attributes that are common to most Database columns. An indexer // has been provided in case a property added by a provider needs to be accessed without a dependency on the provider implementation. public class DbColumn { public bool? AllowDBNull { get; protected set; } public string BaseCatalogName { get; protected set; } public string BaseColumnName { get; protected set; } public string BaseSchemaName { get; protected set; } public string BaseServerName { get; protected set; } public string BaseTableName { get; protected set; } public string ColumnName { get; protected set; } public int? ColumnOrdinal { get; protected set; } public int? ColumnSize { get; protected set; } public bool? IsAliased { get; protected set; } public bool? IsAutoIncrement { get; protected set; } public bool? IsExpression { get; protected set; } public bool? IsHidden { get; protected set; } public bool? IsIdentity { get; protected set; } public bool? IsKey { get; protected set; } public bool? IsLong { get; protected set; } public bool? IsReadOnly { get; protected set; } public bool? IsUnique { get; protected set; } public int? NumericPrecision { get; protected set; } public int? NumericScale { get; protected set; } public string UdtAssemblyQualifiedName { get; protected set; } public Type DataType { get; protected set; } public string DataTypeName { get; protected set; } public virtual object this[string property] { get; } } } ``` The next part of the API is to expose a ReadOnlyCollection from the DbDataReader The right way of exposing the API would be to add an API in the DbDataReader class called `ReadOnlyCollection DbDataReader.GetColumnSchema()` This is however not possible in .Net Core current version as it would hinder portability of apps created on .Net core with .Net framework. https://github.com/dotnet/corefx/blob/master/Documentation/coding-guidelines/breaking-change-rules.md Based on the contents of the link above, the following rule is allowed `Adding an abstract member to a public type when there are no accessible (public or protected) constructors, or the type is sealed` The restriction is due to type forwarding, which needs the calls to DbDataReader to be forwarded to the .Net framework's DbDataReader. ## Proposal We introduce an interface called IDbColumnSchemaGenerator, in .Net core which can be implemented by a type which can provide the Column Metadata. For DbDataReader, this interface needs to be implemented by the subclasses of the `DbDataReader` to provide the Column metadata provided by the `DbDataReader` ``` C# namespace System.Data.Common { public interface IDbColumnSchemaGenerator { System.Collections.ObjectModel.ReadOnlyCollection GetColumnSchema(); } } ``` The subclasses of DbDataReader in the ADO.Net providers implement this interface. ``` C# public class SqlDataReader : DbDataReader, IDbColumnSchemaGenerator { public ReadOnlyCollection GetColumnSchema(){ return ... ; } } ``` In .Net core, to allow the Column Metadata to be exposed from the DbDataReader, an extension to the DbDataReader will be provided. This extension has the same signature as the interface method. ``` C# using System.Collections.ObjectModel; namespace System.Data.Common { public static class DbDataReaderExtension { public static System.Collections.ObjectModel.ReadOnlyCollection GetColumnSchema(this DbDataReader reader) { if(reader is IDbColumnSchemaGenerator) { return ((IDbColumnSchemaGenerator)reader).GetColumnSchema(); } throw new NotImplementedException()); } } } ``` It is recommended that the extension be used by consumers, for compatibility with .Net Framework. The details are mentioned in the compatibility section below. ## Producer The ADO.Net providers are the producers of the Column Schema. The interface will be implemented by the sub-classes of `DbDataReader` in the ADO.Net providers. E.g. ``` C# class SqlDataReader : DbDataReader, IDbColumnSchemaGenerator { ... public ReadOnlyCollection GetDbColumnSchema() { ReadOnlyCollection metadata = ... ; // Build the list of columns metadata. Each columns metadata is represented by the DbColumn return metadata; // } ... } ``` ## Consumer The consumers can retrieve the column metadata using an extension method on the DbDataReader. This extension will be provided in System.Data.Common For a library consuming the `DbDataReader` the code will look like the following: ``` C# using System.Data.Common; namespace org.example.my { ... public void ProcessMetadata(DbDataReader reader) { ICollection columnMetadata = reader.GetColumnSchema(); } ... } ``` ## Compatibility of libraries written on .Net Core with .Net Framework The extension method will have a different implementation in the **_partial facade_** to get the Schema. The implementation will use the DbDataReader.GetSchemaTable() api which returns the schema as a Datatable. This Datatable will be mapped to a ReadOnlyCollection and returned by the implementation of the extension in the partial facade. # vNext In the next version of .Net we add a Interface to .Net desktop and the the consumers continue to access the schema using the Interface ## Reference Github issue https://github.com/dotnet/corefx/issues/3423 5919 area-System.Net Native shims for libheimntlm inorder to support NTLM Introducing native shims for libheimntlm inorder to support NTLM This PR overwrites #5728 5920 area-System.Threading Configure ThreadPool Hello, There is some way to configure the threadPool and the ConnectionLimit in DNX Core 50?

Thank you 5921 area-System.Drawing Proposal for minimalistic imaging platform ## Proposal for minimalistic imaging platform .NET does not provide a truly portable image format nor portable image IO operations. For example System.Drawing.Bitmap nor WPF's BitmapSource and does not provide generic interface which imposes compile-time constraints. EmguCV's generic image provides the generic interface but is heavily coupled with OpenCV. All mentioned image types do not provide a unified interoperability needed when mixing image-processing algorithms from different libraries. ### Goals: - [ ] to create a portable module for image reading/writing - [x] to create a portable, slim image format such as [DotImaging](https://github.com/dajuric/dot-imaging) has (native array Bgr<byte>[,]) - [x] to create system drawing primitives - such as in [DotImaging.Primitives2D](https://www.nuget.org/packages/DotImaging.Primitives2D/) - [ ] _optionally to create portable video reading and web-camera access module_ ### Proposal To leverage existing structure and components of [DotImaging](https://github.com/dajuric/dot-imaging) framework, but to replace the backing OpenCV part needed for image IO. The first step would be to create a portable image reading/writing module with the most simplistic API (e.g. ImageIO.LoadColor(), LoadGray()...). Options: - a wrapper arround LibGD (@ #2020) - trim down and reuse the existing platform specific module of: [Eto.Forms](https://github.com/picoe/Eto) - includes drawing capabilities as well, or [Splat](https://github.com/paulcbetts/splat). ### Related issues [Proposal for Cross-plat Server-side Image Manipulation Library](https://github.com/dotnet/corefx/issues/2020) - proposal of much broader scale - this proposal resolves the core issue and levaes out separates image processing part managed by other libraries [Accord.NET](http://accord-framework.net/), [Accord.NET Extensions](https://github.com/dajuric/accord-net-extensions), [EmguCV](http://www.emgu.com/wiki/index.php/Main_Page).

This object was being pinned by `GCHandle.Alloc(this)` in the contructor. And it was never freed. This object needs to be pinned during the WebSocket lifecycle because the address of the object is passed to native WinHTTP and used as the context value during callbacks. However, it needs to be manually freed at the proper time after all WinHTTP callbacks are done via closing down the handles. This fix adds Pin() and Unpin() methods to WinHttpWebSocketState and calls them at appropriate times. While fixing this I discovered other places where the object might be left as pinned. The current logic relies on WinHTTP calling the callback with HANDLE_CLOSING before the object would get unpinned. But since the object is pinned very early on, it's possible due to unexpected errors, that the wiring of the WinHTTP callback never gets done. And thus, the object would never have been unpinned. This fix delays the pinning of the object until the right time where it is assured that the WinHTTP callback wiring has been completed. This logic is now similar to the state handling in WinHttpHandler. There is still a work item #2501 to merge these design implementations and share code in the future. Fixes #3256. 5930 area-Infrastructure Generalize story for building multiple package versions See discussion on PR #5916.

If compiled with the interpreter then invoking the delegate returns a `PropertyAndFields` object with the readonly field set as requested. With an attempt to initialise a constant, the compiler will throw `NotSupportedException`, the interpreter return a delegate that throws `FieldAccessException` (or hit an assert in debug). With an attempt to initialise a static property the compiler will return a delegate that throws a `VerificationException` on invocation, the interpreter one that writes to the property (or hit an assert in debug, it unbalances the stack). Attempts to write initialise static fields will work for either, but again unbalances the stack for the interpreted version. The ideal solution would be to throw on the call to `Expression.Bind` which could be easily done by adding more checks to `ValidateSettableFieldOrPropertyMember`. If the backwards compatibility impact was considered too great, the interpreter could be change to throw the same exceptions as the compiler, in those cases where it throws. cc @VSadov @bartdesmet " 5964 area-System.IO Expose existing FileStream.Lock() and FileStream.Unlock() APIs on MacOS/Unix Dear Team, As the subject line states we seek the consideration to add Lock() and Unlock() for FileStream in the contract. The implementation should be straight forward at least for Windows platform. Current .NET 4.61 calls Win32 LockFile underneath: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365202(v=vs.85).aspx Although we don't have access to LockFile for UWP, we do luckily have the brother of it LockFileEx, which also supports async, which is good news. I believe for Linux/BSD/Mac there should be easy equivalent to find as locking on file is very common in old days. Will find all the details if the team is willing to consider the proposal. We could do our own P/Invoke to call the LockFileEx, but it would be much elegant if corefx support that out of box, unless there is significant reason to reject it. 5965 area-System.Linq Expression.ListBind accepts non-addable properties if element list is empty.

I eventually narrowed it down to the fact that it was missing the reference to `Windows.winmd` (or the universal API contract for Windows 10) that contained the types. So suddenly I remembered you guys had WinRT-specific libraries, and I looked into your `project.json` to see how you do it. I eventually figured out you're doing this using some kind of ['targeting pack'](https://github.com/dotnet/corefx/blob/ac67ffac987d0c27236c4a6cf1255c2bcbc7fe7d/src/System.Runtime.WindowsRuntime/src/project.json#L12) package, hosted privately on MyGet.

Postponing the fixes for later given the CI system instabilities with *NIX in the last week. - VirtualNetworkStream.cs:112 Nit: I think you said this will never be canceled at this time, so this can wait until later, but if this does have cancellation requested, it'll end up throwing a cancellation exception that's then caught by the catch block, which will return a task in the Faulted state. Technically it'd be better for the task to be in the Canceled state. In reality, for your testing purposes, it's unlikely to matter, as if the operation is immediately awaited, the caller won't be able to tell the difference. If, however, a caller were to inspect the Status of the returned task once it completed (as they might if they were using ContinueWith), they could tell the difference. - VirtualNetworkStreamTest.cs:110 Random isn't thread-safe, so this call should be protected (or you should use RandomNumberGenerator, which is thread-safe).

Then each P/Invoke to register a callback passes a delegate and a GCHandle, stores both in the CallbackHandle, and passes to libcurl a shim function and the CallbackHandle as the user pointer. The shim when invoked then pulls the relevant function out of the CallbackHandle and invokes it. But, we always use the same functions, for which delegates are cached in statics, both for perf and to keep them from being collected. If we instead had a single P/Invoke we called to store pointers to all of these delegates, then we would no longer need to store the delegates in the CallbackHandle, and we'd only have a single piece of state (the GCHandle) to pass for each invocation, which means we could just pass that as the user pointer and get rid of the CallbackHandle altogether. 5999 area-System.Net System.Net.Http.CurlHandler and Unix Sockets "I previously opened #3153 asking about exposing Unix Socket functionality in the CurlHandler, and @stephentoub closed the issue with [an excellent explanation](https://github.com/dotnet/corefx/issues/3153#issuecomment-139289555). However, as things in .NET Core Land have progressed, I'm wondering again about this. Basically, the **dotnet/corert** project is looking to enable native compilation, which means that C# can potentially be used to create useful, native cross-platform tools, much like Go. It's very common for these command-line applications or services on Linux to need to communicate over Unix Sockets; for example, `/var/run/docker.sock` is used to talk to the local Docker daemon. I had a quick look at the `HttpClient` and `HttpRequestMessage` APIs, and the internal handling of `HttpRequestMessage` by `CurlHandler`. There is a potential opportunity to introduce this functionality in an obscure but workable way without breaking or even changing the public API, by using the `Properties` dictionary on `HttpRequestMessage` (which is a `Dictionary`). One could set a property in here, perhaps like: ``` csharp var message = new HttpRequestMessage(HttpMethod.Get, ""http://localhost/api/list""); message.Properties[""Curl.UnixSocketPath""] = ""/var/run/docker.sock""; ``` `CurlHandler` could then check for this property and set `CURLOPT_UNIX_SOCKET_PATH` using `Interop.Http.EasySetOptionString`. An application or library developer using this feature could easily create extension methods on `HttpClient` to give themselves a nicer syntax. If that API would be acceptable, I'd be happy to have a go at implementing it. Thoughts? " 6001 area-System.Net Enable EventSource logging in CurlHandler We currently have a bunch of tracing in CurlHandler, but it's all guarded behind compile-time flags, making it difficult to use to diagnose issues. This converts that to all be EventSource-based logging.

There's a large comment about how this is done to avoid concurrent use of the buffer when concurrent read operations are issued, but we should be able to work around that using something similar to what I previously did for WriteAsync and FlushAsync, with the HasActiveBufferOperation mechanism (https://github.com/dotnet/corefx/pull/2929). As it currently stands, it appears that when async reads are performed against a Win32FileStream and those reads are smaller than the file stream's buffer, all such reads will be made synchronous, either because they're pulling from the buffer or because they're blocking waiting for the buffer to be filled. cc: @ericstj, @ianhays, @JeremyKuhne 6008 area-System.Net System.Net.Cache whole namespace is not in corefx?

However, there are a few key differences that need to be taken into account for CurlHandler. For example, popular implementations of gssapi and Negotiate on Unix do not include implementations for fallback to NTLM. So whereas including “Negotiate” in WinHttpHandler often allows code on Windows to use NTLM if Kerberos is not available, the current state of CurlHandler often does not. And although NTLM has some known issues, if it's the only option for a scenario where a Unix front-end needs to communicate with a Windows back-end (say because the front-end doesn't have Kerberos infrastructure available and the back-end only has Windows authentication enabled), we still want it to be possible for a developer to write an app that communicates with that back-end: the underlying platform supports it, so if the developer explicitly wants it, CurlHandler sitting in the middle shouldn't get in the way. As such, this commit enables NTLM to be used, essentially removing the blocking of it that was previously done. However, it's not enabled by default for arbitrary credentials; rather, it's only enabled when a credential added to a CredentialCache explicitly specifies ""NTLM"". That way, it's available for a dev to opt-in to if desired, but just providing a NetworkCredential to CurlHandler will not use NTLM. cc: @bartonjs, @davidsh, @cipop, @kapilash, @chrisrpatterson, @ericeil " 6039 area-System.IO Win32FileStream will issue a seek on every ReadAsync call Full description is here: https://ayende.com/blog/173345/the-cost-of-async-i-o?key=227b21e219594be48ca03bc8312b08b9 But the gist of it is that we are trying to call ReadAsync on a file that is located on a remote share. Using ReadAsync, we saw a really horrible performance degradation.

but they don't tell you if it succeeded or not. The problem with these methods is that if there is more than one element in `source` (or more than one matching element in case of `predicate`) they all throw a `System.InvalidOperationException`. That is fine if more than one element is an error or very rare. If more than one element is common or expected then this will cause major slow downs. Additionaly, in cases of (example: int collections), default(int) is 0, which wouldn't tell the caller whether the operation succeeded (returning the item 0) or not (returning the default 0). ## Proposal ``` diff namespace System.Linq { public static class Enumerable { public static TSource Single(this IEnumerable source); public static TSource Single(this IEnumerable source, Func predicate); public static TSource SingleOrDefault(this IEnumerable source); public static TSource SingleOrDefault(this IEnumerable source, Func predicate); + public static bool TrySingle(this IEnumerable source, out TSource element); + public static bool TrySingle(this IEnumerable source, Func predicate, out TSource element); public static TSource First(this IEnumerable source); public static TSource First(this IEnumerable source, Func predicate); public static TSource FirstOrDefault(this IEnumerable source); public static TSource FirstOrDefault(this IEnumerable source, Func predicate); + public static bool TryFirst(this IEnumerable source, out TSource element); + public static bool TryFirst(this IEnumerable source, Func predicate, out TSource element); public static TSource Last(this IEnumerable source); public static TSource Last(this IEnumerable source, Func predicate); public static TSource LastOrDefault(this IEnumerable source); public static TSource LastOrDefault(this IEnumerable source, Func predicate); + public static bool TryLast(this IEnumerable source, out TSource element); + public static bool TryLast(this IEnumerable source, Func predicate, out TSource element); public static TSource ElementAt(this IEnumerable source, int index); public static TSource ElementAtOrDefault(this IEnumerable source, int index); + public static bool TryElementAt(this IEnumerable source, int index, out TSource element); } public static class Queryable { public static TSource Single(this IQueryable source); public static TSource Single(this IQueryable source, Expression> predicate); public static TSource SingleOrDefault(this IQueryable source); public static TSource SingleOrDefault(this IQueryable source, Expression> predicate); + public static (bool success, T value) TrySingle(this IQueryable source); + public static (bool success, T value) TrySingle(this IQueryable source, Expression> predicate); + public static bool TrySingle(this IQueryable source, out TSource element); + public static bool TrySingle(this IQueryable source, Expression> predicate, out TSource element); public static TSource First(this IQueryable source); public static TSource First(this IQueryable source, Expression> predicate); public static TSource FirstOrDefault(this IQueryable source); public static TSource FirstOrDefault(this IQueryable source, Expression> predicate); + public static (bool success, T value) TryFirst(this IQueryable source); + public static (bool success, T value) TryFirst(this IQueryable source, Expression> predicate); + public static bool TryFirst(this IQueryable source, out TSource element); + public static bool TryFirst(this IQueryable source, Expression> predicate, out TSource element); public static TSource Last(this IQueryable source); public static TSource Last(this IQueryable source, Expression> predicate); public static TSource LastOrDefault(this IQueryable source); public static TSource LastOrDefault(this IQueryable source, Expression> predicate); + public static (bool success, T value) TryLast(this IQueryable source); + public static (bool success, T value) TryLast(this IQueryable source, Expression> predicate); + public static bool TryLast(this IQueryable source, out TSource element); + public static bool TryLast(this IQueryable source, Expression> predicate, out TSource element); public static TSource ElementAt(this IQueryable source, int index); public static TSource ElementAtOrDefault(this IQueryable source, int index); + public static (bool success, T value) TryElementAt(this IQueryable source, int index); + public static bool TryElementAt(this IQueryable source, int index, out TSource element); } } ``` ## Original I'd like to propose a new LINQ method: `TrySingle`. The idea is pretty much the same as the existing `Single` method except it does not throw an exception when there is not only a single item in the sequence. To do this I made to modifications to the `Single` contract: 1. First the method returns `bool`. `true` if the sequence contains exactly one item, `false` otherwise. 2. I added an out parameter of type `TSource`. This will ""hold"" the single element on success. On failure it is filled with `default(TSource)`. I have found this method very useful in my own code and if accepted can quickly put together a pull request.

Is the below by design? I narrowed it down to this scenario: XUnit runner process and the ILC's input project both refer to the same version of the NETStandard.Library. XUnit runner loads System.Console.dll from the shared packages cache location. ILC wants to compile an user's app using the same System.Console.dll specified in the project.json file and opens a `MemoryMappedFile` on it which errors out with: ``` The process cannot access the file 'C:\Users\schellap\.nuget\packages\runtime.win7.System.Console\4.0.0-rc2 -23811\runtimes\win7\lib\dotnet5.4\System.Console.dll' because it is being used by another process. ``` To repro, 1.

When that happens the existing work items that are still executing have no (built-in) way to find out. They cannot cancel themselves to speed up the failure/exit case. `ParallelLoopState` should expose a `CancellationToken` that becomes signaled when the loop aborts for any reason. There is a workaround for this available: Users can catch all exceptions, signal a custom token, then `throw;`. It would be nicer and possibly faster if this was built-in, though. 6107 area-System.Net Add LocalEndPoint and RemoteEndPoint properties to TcpClient Due to https://github.com/dotnet/corefx/pull/5953 it is not possible to get this information.

Technically it allows for cases when `owningConnection` is non-null but if of type other than `SqlConnection` - then casts will just fail with an exception. Is that intended? Should `sqlOwningConnection` be used instead? Maybe `as` should be replaced with a cast instead? 6111 area-System.Net Fix in SafeCredentialHandle when using default credentials This PR fixes the Null Reference Exception when default credentials are used. 6113 area-System.Net Merge master to dev/negotiatestream Some changes are necessary to pick up to unblock the build. 6114 area-System.Net Negotiate Stream on Unix does not fail with invalid target `NegotiateStream.AuthenticateAsClientAsync` does not fail for invalid target. 6115 area-System.Data Suspicious timeout computations in System.Data.SqlClient.SqlInternalConnectionTds `System.Data.SqlClient.SqlInternalConnectionTds` has `LoginNoFailover()` and `LoginWithFailover()` methods which differently compute `timeoutUnitInterval`. `LoginWithFailover()` does this: ``` if (timeout.IsInfinite) { timeoutUnitInterval = checked((long)ADP.FailoverTimeoutStep * ADP.TimerFromSeconds(ADP.DefaultConnectionTimeout)); } else { timeoutUnitInterval = checked((long)(ADP.FailoverTimeoutStep * timeout.MillisecondsRemaining)); } ``` and `LoginNoFailover()` does this: ``` if (timeout.IsInfinite) { timeoutUnitInterval = checked((long)(ADP.FailoverTimeoutStep * (1000L * ADP.DefaultConnectionTimeout))); } else { timeoutUnitInterval = checked((long)(ADP.FailoverTimeoutStep * timeout.MillisecondsRemaining)); } ``` `else`-branches are exactly the same. Yet one `if` branch uses `TimerFromSeconds()` which returns number of ticks for given number of seconds and another uses multiplication by one thousand. Why the difference? 6116 area-System.Data Suspicious comment on use of GC.KeepAlive() in System.Data.SqlClient.SqlConnection.TryOpen() `System.Data.SqlClient.SqlConnection.TryOpen()` has this comment ``` // does not require GC.KeepAlive(this) because of OnStateChange ``` I don't see an explicit call to `OnStateChange()` anywhere in that method. Even if there's a call chain which leads to `OnStateChange()` from that method it'd be more reliable to put `GC.KeepAlive()` call so that code isn't broken by later changes. It's worth remembering that failing to use `GC.KeepAlive()` can causes the subtlest race conditions. 6118 area-System.Data Suspicious comment about non-existing lock in System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning() `System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()` has this warning: ``` // call OnError outside of _ErrorCollectionLock to avoid deadlock ``` there's nothing called `_ErrorCollectionLock` or similarly in the codebase. The comment is full of magic. 6119 area-System.Data System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning() silently swallows error conditions `System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()` has a Debug.Assert check that the errors connection is not empty and also this excellent `if`: ``` SqlConnection exception = null; //later... if (temp != null && temp.Count > 0) //craft exception } //later ... if (exception != null ) { //do a lot of cool stuff } // else do nothing ``` which means that allowing to have this function called when there're no elements in `temp` leads to a logical error - no error indication is given and the connection is just silently closed. Those `Debug.Assert`s should instead throw something like `InvalidOperationException`. 6120 area-System.Data Suspicious error object creation in System.Data.SqlClient.TdsParserStateObject.OnTimeout() "`System.Data.SqlClient.TdsParserStateObject.OnTimeout()` goes like this: ``` _internalTimeout = true; // lock protects against Close and Cancel lock (this) { if (!_attentionSent) { AddError(new SqlError( WHATEVER )); ``` If you look through usage of `_internalTimeout` elsewhere in the same class you may notice that `ReadSniError()` also checks `_internalTimeout` and optionally sets `fail` local variable. It's unclear whether this may cause `ThrowExceptionAndWarning()` being called with empty ""errors"" collection which would cause https://github.com/dotnet/corefx/issues/6119 I guess that `OnTimeout()` should add a new `SqlError()` no matter if `_attentionSent` is set.

On Windows, pending async I/O keeps the native socket alive (unless someone explicitly calls `Dispose` on the socket), so we need to have similar behavior on *nix. The ""meat"" of the change is to track the `SafeCloseSocket` instance in `SocketAsyncContext` (instead of the file descriptor), and to pass these as SafeHandles to the interop layer whenever possible. Unfortunately, System.Native.so's functions mostly take `int32_t` file descriptor arguments. Fixing this the ""pretty"" way would involve changing all of these to `intptr_t`, and then using the normal p/invoke `SafeHandle`->`IntPtr` marshaling. But updating all of the signatures in System.Native.so is quite a project, as we'd need to keep both the old _and_ new signatures for some time. For now, I've done manual `SafeHandle`->`int` marshaling, and will open an issue for cleaning this up further. We will need to think some more about how this interacts with `SocketAsyncEngine`; I believe there is a race there that will lead to problems, but I don't think this change makes it any worse.

For example (C# version): ``` List items = new List() { 1, 2, 3 }; //All permutations of 2 //a) No repeated elements and order doesn't matter (1-2 = 2-1) //1-2, 1-3, 2-3 //b) No repeated elements and order matters (1-2 != 2-1) //1-2, 1-3, 2-1, 2-3, 3-1, 3-2 //c) Repeated elements and order doesn't matter //1-1, 1-2, 1-3, 2-3, 2-2, 3-3 //d) Repeated elements and order matters //1-1, 1-2, 1-3, 2-1, 2-3, 2-2, 3-1, 3-2, 3-3 //All permutations of 3, etc. ``` With a constant number of elements (e.g., 3, as proposed in the aforementioned example), implementing an algorithm to deliver this functionality is quite straightforward (i.e., as many nested loops as elements). On the other hand, with a variable number of elements (e.g., any number between 3 and 10), the complexity is notably increased. Even in the first simpler scenario, being able to just type `myPermutations = myCollection.Permutations(2);` would be certainly helpful. My proposal is to create a new method for 1D collections delivering all the possible permutations among its elements. It might be called ""Permutations"" and accept various arguments, like number of items per permutation or type of permutation (as shown in the example above). At least for the first version, I think that the best format for the output variable is a dictionary of integers (key) and collection of objects (value). By assuming that the first version will be included within the `System.Array` methods, I guess that the dictionary should be of type (C#) `Dictionary`. In case of deciding to go ahead with this proposal, I would like to implement it myself.

That doesn't make much sense imo when our underlying stream already implements Stream and possibly has its own specific asynchronous methods that it wants to be used. We should consider modifying the DeflateStream asynchronous Write and Flush methods to do like ReadAsync does and directly call the underlying stream's asynchronous methods. If the underlying stream doesn't override WriteAsync then there will be no change from the current behavior. @stephentoub 6173 area-System.Net Race conditions in SocketAsyncEngine "In [`SocketAsyncEngine.EventLoop`](https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/src/System/Net/Sockets/SocketAsyncEngine.Unix.cs#L80), there is a window where `WaitForSocketEvents` has returned an event for a socket, but we have not yet deferenced the event's `GCHandle` to obtain the socket's `SocketAsyncContext`. In that window, another thread may close the socket and free the `GCHandle`. This can lead to some problems, depending on what _else_ happens in this window. The most egregious of these is probably as follows: If another `GCHandle` is allocated for another `SocketAsyncContext`, when we will misattribute the events to the new socket. For the most part this won't matter, as it will simply mean that we have to retry some operation again. But if the new socket has a pending ""connect"" operation, and we receive a ""write"" event, we'll think the new socket is connected, and there is likely no way we can recover from this. We need to find a way to synchronize the freeing of these handles with any pending calls to `WaitForSocketEvents` _or_ switch to a handle allocation mechanism that does not re-use handles.

I understand part of the motivation for removing these fields is to keep the reference assemblies small. Keeping the fields necessitates keeping the type definitions for the types of the fields and this can cascade into many more types / members being included thus increasing size. Cutting private fields for classes is fine as it's unobservable. Unfortunately for structs fields are observable irrespective of their accessibility and must be maintained in reference assemblies. The only action I think that can be done to curtail the number of types a struct brings in is the following: > A reference assembly can represent an inaccessible struct field which is a reference type as `object`. Essentially `class`, `interface`, `delegate` and generic type parameters constrained to `class` can be transformed to object. ``` csharp // Implementation assembly private interface IBigInterface { ... } public struct S { private IBigInterface _field; } // Reference assembly public struct S { private object _field; } ``` This is unobservable to the compiler and can help limit the number of types brought it. 6186 area-System.Net Fix race in SocketAsyncEngine "In `SocketAsyncEngine.EventLoop`, there is a window where `WaitForSocketEvents` has returned an event for a socket, but we have not yet dereferenced the event's 'GCHandle' to obtain the socket's `SocketAsyncContext`. In that window, another thread may close the socket and free the `GCHandle`. This can lead to some problems, depending on what else happens in this window. The most egregious of these is probably as follows: If another `GCHandle` with the same value is allocated for another `SocketAsyncContext`, then we will misattribute the events to the new socket. For the most part this won't matter, as it will simply mean that we have to retry some operation again. But if the new socket has a pending ""connect"" operation, and we receive a ""write"" event, we'll think the new socket is connected, and there is likely no way we can recover from this. This change switches to a new handle allocation strategy that does not permit re-use of a given handle with a given event port. Handle values increase monotonically until we reach the handle's maximum size; at that point, we allocate a new event port, and start allocating handle values from zero. The old port will be freed once all of the handles associated with that port have been freed. On 64-bit platforms, the maximum handle value is `long.MaxValue`, which effectively means that we will never need to allocate a new event port. On 32-bit platforms, we top out at `int.MaxValue`, and so a long-running process may occasionally need to allocate a new port. Since this limit is reachable on 32-bit, but is in any case hard to reach, we artificially impose a very low limit in ""debug"" builds, so we can be sure to exercise the rollover to the new event port.

The [most popular SO answer](http://stackoverflow.com/a/340454/4077294) on the topic is over 10 lines, which is less than ideal. Also, it's pretty allocation-heavy since it instantiates 3 `Uri` objects and 3 strings. ## Proposal ### Signature The method would look like this: ``` csharp public static string CreateRelativePath(string @from, string to) ``` - **from** would be the directory path for which the newly returned path would be relative to. It could be absolute or relative. - **to** would be the path for which the returned path would point to. It could also be absolute or relative. If either paths are relative, they are resolved in relation to the process' current directory (e.g. via `Path.GetFullPath`). ### Example inputs/outputs ``` csharp Path.CreateRelativePath(@""C:\Users"", @""C:\Users\James""); // returns James Path.CreateRelativePath(""/usr/local/bin"", ""/usr/bin""); // returns ../../bin Path.CreateRelativePath(""lib"", ""../test""); // returns ../../test ``` What do you guys think?

Unfortunately, some handle management got lost in transliteration: The VM held these handles in stack-allocated classes similar to SafeHandle, which means that the dtor fired on block exit. Since the VM never visibly called CryptDestroyKey (or the appropriate function for the handle type) this caused a lot of Disposes to be converted to Finalizes. And that exposed a handle-order-free problem. (The SafeKeyHandle has an underlying relationship with the SafeProvHandle that allocated it, if the SafeProvHandle is freed first, the SafeKeyHandle free returns false. And largely they're both being finalized). 6211 area-System.Security SafeKeyHandle depends on SafeProvHandle, and should track that A SafeKeyHandle is allocated from a SafeProvHandle. The SafeKeyHandle needs the SafeProvHandle to not be freed first. So the SafeKeyHandle should track its parent/child relationship similar to how SafeInteriorHandle does. 6218 area-System.Net Lots of timeouts on Unix in DualMode connect tests Some of the tests are hanging in EndConnect, e.g. ``` 00007F6A6C94B150 00007F6A6D897DF0 System.Net.Sockets.SocketAPMExtensions.EndConnect(System.Net.Sockets.Socket, System.IAsyncResult) 00007F6A6C94B170 00007F6A6D89784B System.Net.Sockets.Tests.DualMode.DualModeBeginConnect_IPEndPointToHost_Helper(System.Net.IPAddress, System.Net.IPAddress, Boolean) 00007F6A6C94B200 00007F6A6D897718 System.Net.Sockets.Tests.DualMode.b__45_0() 00007F6A6C94B220 00007F6A6D79D36E Xunit.Assert.RecordException(System.Action) 00007F6A6C94B250 00007F6A6D79D2FB Xunit.Assert.Throws[[System.__Canon, mscorlib]](System.Action) 00007F6A6C94B280 00007F6A6D8976AA System.Net.Sockets.Tests.DualMode.BeginConnectV6IPEndPointToV4Host_Fails() ``` Others are timing out, e.g. ``` 10:32:46 System.Net.Sockets.Tests.DualMode.ConnectAsyncV4IPEndPointToV4Host_Success [FAIL] 10:32:46 Timed out while waiting for connection 10:32:46 Expected: True 10:32:46 Actual: False 10:32:46 Stack Trace: 10:32:46 at System.Net.Sockets.Tests.DualMode.DualModeConnectAsync_IPEndPointToHost_Helper(IPAddress connectTo, IPAddress listenOn, Boolean dualModeServer) 10:32:46 at System.Net.Sockets.Tests.DualMode.ConnectAsyncV4IPEndPointToV4Host_Success() ``` 6220 area-Infrastructure Incremental build does not work outside Windows RIght now if you build a project twice in a row, the second build re-runs some targets that should be up-to-date already. When I build System.Private.Uri twice on Windows, almost all of the targets are skipped on the second try. On Linux, some targets are re-run. Namely, the CoreResGen and CoreCompile targets are both run again, and those are probably two of the most expensive targets, relatively speaking. This may be due to some difference in the x-plat MSBuild we are using. I have tried to use the CoreCLR version of MSBuild on Windows to see if this would reproduce, but there seems to be an issue with csc in that case (something about a COM interface cast failing). Notably, though, it DOES try to rerun the CoreResGen and CoreCompile steps like it does on Linux, and skips the same targets that it does on Linux. So I strongly suspect this is a bug in the CoreCLR-MSBuild we are using. @joperezr 6222 area-System.Net Make setup-kdc.sh executable. cc @kapilash @rahku @vijaykota Refer this [comment](https://github.com/dotnet/corefx/pull/6139#issuecomment-185936932) 6223 area-System.Console WindowAndCursorProps.Title_Set failed on Windows 10 http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/outerloop_win10_debug/91/consoleFull ``` 10:33:10 WindowAndCursorProps.Title_Set [FAIL] 10:33:10 System.IO.IOException : No process is on the other end of the pipe 10:33:10 Stack Trace: 10:33:10 d:\j\workspace\outerloop_win---0cba2915\src\System.Console\src\System\ConsolePal.Windows.cs(539,0): at System.ConsolePal.set_Title(String value) 10:33:10 d:\j\workspace\outerloop_win---0cba2915\src\System.Console\src\System\Console.cs(265,0): at System.Console.set_Title(String value) 10:33:10 d:\j\workspace\outerloop_win---0cba2915\src\System.Console\tests\WindowAndCursorProps.cs(107,0): at WindowAndCursorProps.Title_Set() ``` 6224 area-Infrastructure Windows 7 outer loop test runs failing finding vcvarsall.bat "``` 05:45:09 d:\j\workspace\outerloop_win---627ab81b>call ""C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat"" x86 && Build.cmd /p:ConfigurationGroup=Release /p:WithCategories=""InnerLoop;OuterLoop"" /p:TestWithLocalLibraries=true 05:45:09 '""C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat""' is not recognized as an internal or external command, 05:45:09 operable program or batch file. ``` " 6226 area-System.IO DeletedTests.FileSystemWatcher_Deleted_Negative failed in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/osx_release_tst_prtest/1011/console ``` 13:40:44 DeletedTests.FileSystemWatcher_Deleted_Negative [FAIL] 13:40:44 Should not observe a deleted event within 500ms 13:40:44 Expected: False 13:40:44 Actual: True 13:40:44 Stack Trace: 13:40:44 at Utility.ExpectNoEvent(WaitHandle eventOccurred, String eventName, Int32 timeout) 13:40:44 at DeletedTests.FileSystemWatcher_Deleted_Negative() ``` 6230 area-System.Runtime Add Arm64 support in RuntimeInformation Currently there is no Arm64 support in CoreFX.

This occurs when the server sends `Content-Length`. When using `Transfer-Encoding: chunked`, both .NET Framework and .NET Core throw a `System.IO.IOException` but the inner exceptions seem like the error is being handled differently. Oddly, when using HTTP response `Stream.Read` (not `async`), `Content-Length` works just fine in both .NET Core and .NET Framework and `Transfer-Encoding: chunked` throws in both cases. I tested .NET Core with `dnx run` and `dotnet run` and tested .NET Framework with Visual Studio 2015's F5 experience in a .csproj as well as `dnx run`. I have not tested this on any other operating system. Library versions and a minimal repro are available in this project. [CloseTooEarly.zip](https://github.com/dotnet/corefx/files/137222/CloseTooEarly.zip) This is concerning because it seems that the .NET Core HTTP client is less strict about the `Content-Length` header, which is (as far as I know) is strong assertion by the server of how much it will sent and should therefore throw to not risk data corruption. Also, there seems to be inconsistency between the `async` and non-`async` cases. 6232 area-Serialization Move CoreCLR-only serialization tests to a separate file We have internal lab run of serialization tests on corefx for NetNative which involve these tests affecting other tests because of compilation failure so this is to move them out to a separate file until that issue is fixed. @SGuyGe @shmao @zhenlan 6235 area-System.Net On Ubuntu 14.04 CoreFX build hangs while Test Execution I have been trying to build CoreFX on Ubuntu but every time the build hangs while performing Test Execution for System.Net.Security.Unit.Tests with System.TimeOutException.

After extending the scope of _queueLock in HandleEvents, I noticed that it became largely redundant with _closeLock. So we also remove _closeLock, and just use _queueLock for everything.

I've fixed those call sites to include an appropriate inner exception. - Cleaned up a few error messages. - Fixed one place where I was overzealous in mapping exceptions to IOException cc: @ericeil, @kapilash Fixes https://github.com/dotnet/corefx/issues/6268 6277 area-System.Net Add more Http response stream tests Building on PR #6250, added more response stream tests dealing with invalid response body transfer semantics. I still plan to move the localhost server (recently added to these Http tests) to be Azure based.in the near future. 6281 area-System.Net Rewrite WebUtility.HtmlEntities to minimize array/substring allocations I was browsing the `WebUtility` source code recently and noticed there a huge static array allocation that was never actually used. In addition to that, all of the strings in the array were being `Substring`'d in a loop to initialize a dictionary, which added even more unnecessary allocations. I [rewrote](https://gist.github.com/jamesqo/dda32f6e7a4154053862) the code so it straight-up initializes the dictionary as a literal, using C# 6's new dictionary initializers feature. The new code also passes in a predefined capacity to the dictionary, so there's no resizing taking place when elements are added. 6285 area-System.Net Fix WinHttpHandler memory leaks The WinHttpHandler was leaking a lot of objects in cases where an explicit Dispose was not done for the various HttpResponseMessage related objects. It was leaking because there was a cycle between the strong GCHandle of WinHttpRequestState and the objects contained within it. To break the cycle, we now clear out object references within WinHttpRequestState that are no longer needed once the SendRequest phase is completed. There was also a leak of a pinned GCHandle and related memory in WinHttpResponseStream. The free'ing of that allocated GCHandle was done in the Dispose(bool disposing) method. However, it wasn't being called when disposing=false (i.e. a finalizer). Since it is a pinned GCHandle, it needed to be freed in all cases. Fixes #5927. 6291 area-System.Net Response stream reads should return error for insufficient data "WinHttpResponseStream was not tracking the amount of data read when the response used 'Content-Length' semantics. So, if the amount of bytes read from the server was less than expected, we did not return an error. This was different behavior than .NET Framework. Fixed WinHttpResponseStream so that it will track the total number of bytes read and compare it to the expected number of bytes if using 'Content-Length' semantics. Note that we don't do this checking if the HTTP request is a HEAD request. That is because the definition of that HTTP verb is to return headers ""as-if"" it was returning a real response body. So, the 'Content-Length' might be set but there is no response body for a HEAD request. For cases of using 'Transfer-Encoding: chunked' semantics for the response body, there is already error checking at the lower HTTP layer in WinHTTP. Fixes #6231.

Exit code 143. 6308 area-System.Numerics Additional overloads in some System.Math methods to support more types NOTE: I wrote a first ticket in CoreCLR (https://github.com/dotnet/coreclr/issues/3204), even did a PR for `int.Round` (https://github.com/dotnet/coreclr/pull/3232); but I have been suggested to move it here. For the time being, I will keep some additional comments in that CoreCLR issue, so you might want to take a look there. `Math.Round` can only deal with `decimal` and `double` arguments, what is quite arbitrary as far as these functionalities might also be used with integer types (e.g., `int` or `long`). There is no difference between removing all the digits after 6 in 1.5658 and in 15658, but .NET treats both situations differently. In the first case, it is possible to use `Math.Round` right away; in the second case, two additional steps would be required: either converting to a decimal type or to string and use `Substring`; and then back to the original integer type. Other function with restricted input types is `Math.Pow` which only accepts `double` type inputs. I have been in quite a few scenarios where I had to convert `decimal` variables to `double` (and then back to `decimal`) just to use this function. Equivalent ideas are applicable to other `System.Math` methods which only work with `double` variables. In case of deciding to go ahead and by assuming that such an option is possible, I would like to take care of the actual (in-principle-C#) implementation myself. 6309 area-System.Threading RunAsyncTaskAwaiterTests failed in OuterLoop CI on Windows http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/outerloop_win10_debug/97/consoleFull ``` 22:53:45 System.Threading.Tasks.Tests.TaskAwaiterTests.RunAsyncTaskAwaiterTests [FAIL] 22:53:45 After completion, excepted all GetResult calls to completed successfully 22:53:45 Expected: True 22:53:45 Actual: False 22:53:45 Stack Trace: 22:53:52 d:\j\workspace\outerloop_win---0cba2915\src\System.Threading.Tasks\tests\System.Runtime.CompilerServices\TaskAwaiterTests.cs(204,0): at System.Threading.Tasks.Tests.TaskAwaiterTests.RunAsyncTaskAwaiterTests() ``` 6311 area-System.Net DnsEndPointTest.Socket_StaticConnectAsync_HostNotFound timed out in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/rhel7.2_debug_tst/38/console ``` 08:17:47 System.Net.Sockets.Tests.DnsEndPointTest.Socket_StaticConnectAsync_HostNotFound [FAIL] 08:17:47 Timed out while waiting for connection 08:17:47 Expected: True 08:17:47 Actual: False 08:17:47 Stack Trace: 08:17:47 at System.Net.Sockets.Tests.DnsEndPointTest.Socket_StaticConnectAsync_HostNotFound() ``` 6312 area-System.Net [Apline] Need a better approach to fix CMSG_NXTHDR on Alpine Linux (musl-libc) The current master ([`5b793bc`](https://github.com/dotnet/corefx/tree/5b793bc735d6a63b7f4be466df3351008b27a426)) breaks the native build (`corefx/build.sh native`) at 70% on Alpine Linux with the following error: ``` ash /root/corefx/src/Native/System.Native/pal_networking.cpp:1311:31: error: cast from 'unsigned char *' to 'struct cmsghdr *' increases required alignment from 1 to 4 [-Werror,-Wcast-align] controlMessage = CMSG_NXTHDR(&header, controlMessage)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/sys/socket.h:267:10: note: expanded from macro 'CMSG_NXTHDR' ((struct cmsghdr *)__CMSG_NEXT(cmsg)))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``` Code comparison between glibc and musl-libc: - musl-libc: https://fossies.org/dox/musl-1.1.14/include_2sys_2socket_8h.html#a4f70853d9633fb80428189cd7bb292d0 (click on `__CMSG_NEXT` in that macro to see `unsigned char*` cast) - glibc: http://lxr.free-electrons.com/source/include/linux/socket.h#L89 (click on `__cmsg_nxthdr` in the called macro to notice that it returns `cmsghdr *`) https://github.com/dotnet/corefx/pull/6263 provides a workaround to turn that warning off inline for this particular call to macro and then restores it using Clang's `pragma`tic directives.

"In reviewing the test refactoring for DateTimeFormatInfo, I was about to ask if the test for ReadOnly should be asserting NotSame, Same, or a contextual-version thereof. MSDN doesn't describe; I can certainly see what the implementation does; but the question is: ""is the sameness guaranteed?"" If so, we should test it. If we guarantee it's a copy when !IsReadOnly then we should assert NotSame, and then mutuate the original and see that it's not preserved. NotSame on !IsReadOnly => IsReadOnly seems like a pretty obvious guarantee to me (and that it's not receptive to mutation on the original), but since I wasn't sure about the already-is-read-only case I decided that a standalone issue was probably best.

Note that the `==` operator and `Equals(Complex)` method have different code, and this causes discrepancies. The problem mainly occurs with complex numbers containing `double.NaN`, as `double.NaN == double.NaN` returns `false`, but `double.NaN.Equals(double.NaN)` returns `true`. ## Example As such, we get a strange example where the following code doesn't work as expected: ``` Complex complex1 = new Complex(double.NaN, double.NaN); Complex complex2 = new Complex(double.NaN, double.NaN); complex1.Equals(complex2); // True as expected complex1.Equals((object)complex2); // False as unexpected complex1 == complex2; // False as expected ``` ## Solution Fix the implementation of `Equals(object)` to the following: ``` public override bool Equals(object obj) { if (!(obj is Complex)) return false; return Equals((Complex)obj); } ``` This may have breaking change implications, but IMO should be fixed.

It follows the following alogrithm - If the host is an IPV6 address and has does not start with a square bracket, add square brackets around the host.

Failing to reset that state causes non-deterministic ""leaks"" that are very hard to diagnose. This is especially relevant in ASP.NET and in unit testing scenarios. The thread pool is a global process resource. Generally, code should play nice with such resources but bugs should not be catastrophic. The .NET thread pool should reset all of these items (where practical) after the execution of each work item. I see no valid scenario why someone might want to set these values and have them persist because there is no way to make that deterministic. Regarding the above items I could not find documentation that specifies which one of them are reset or are not reset. This behavior should be documented and contractually guaranteed. Ideally, setting `Thread` properties should fail outright but that might not be possible for compatibility reasons. The behavior changes proposed here should work for the legacy thread pool API as well as for the TPL. I have not added the execution context and logical call context to the list because I lack the technical understanding to recommend anything about them. Maybe they should be reset as well. I have not added `ThreadStatic` and other forms of thread-static variables because those are often useful for caching scenarios. Resetting them would be a bad idea.

Note that ""fn-delete"" is interpreted the same way (but _should_ be the only one interpreted this way). On Linux (over SSH and RDP), with the same `TERM`, the key code being sent by my MacBook's ""delete"" key still ends up as `^?`, but it is interpreted correctly as `Backspace`. `System.Console` is not the only place where I've seen OS X's Terminal defaults cause funny things with the ""delete"" key. In fact, it seems to be so much an issue that Terminal has a setting to have ""delete"" send `^H`, which is then interpreted as `Backspace`. However, it would be nice not to have to do this :smile: and I sure would like to know how to fix it.

The request handle object for the stream (SafeWinHttpHandle) was part of the strong root chain in WinHttpRequestState. And even when the WinHttpResponseStream object was finalized (implicit Dispose), the request handle was not finalized and thus leaks were happening. To address this, the request handle object reference is now cleared from the WinHttpRequestState object (along with other object references) once the WinHttpResponseStream is created. WinHttpResponseStream then gets passed the request handle reference. Then normal finalizer rules can apply to both WinHttpResponseStream and the request handle. Once the request handle gets disposed (via finalizing), native WinHTTP will send a final status callback (HANDLE_CLOSING) and that is how the state object will then get unrooted and freed. Tested this fix with WCF streaming scenarios and used WinDBG to verify the heaps. There are future plans to improve this code via refactoring as part of #2501.

I can't reproduce the problem locally, even if I try to artifically induce the failure. I'm guessing that the timing works out differently on the CI machines, making this (somewhat) more likely, and the only legitimate case I can see where this would happen is if the client closes the TCP connection before the server has finished reading all bytes. Increasing the linger time should help with that, so let's give it a try.

This is referring to the difference between `clean.cmd /b` and `clean.sh -b`. I know these were done to match the usual ""OS standard"" flag syntax, but I think it would be simpler if these were just the same across platforms (i.e. `clean -b` everywhere). I'm often typing the wrong flag after I've been working on one system for a while and then move to another. Additionally, `dotnet` has just made all systems use the ""hypen-flag"" syntax instead of allowing ""slash-syntax"" on Windows, and it seems to work fine there. Anyone else feel the same way?

For System.Xml.XPath, we're missing 7 lines of coverage. To fulfill the uncovered lines we would need to either create new tests for them or port 1 ToF tests to the open. Those tests are: - [ ] System.Xml.XPath\4.0.0.0\XDocument\System.Xml.XPath.XDocument.Tests_FullRun.XML Coverage reports, coverage xml files, and detailed json lists of each piece of missing coverage and the corresponding ToF test that fills it are available on request.

There's a ton of text in them, so much that I end up just ignoring them, deleting everything, and writing my own message. Plus, for PRs with a single commit, it appears the template text takes precedence over the normal behavior on GitHub of using the commit's description, which means extra work to get the contents of the commit message into the PR description.

Community are asking to have a standard way to manage DbProviderFactory to write provider agnostic code in libraries. https://github.com/dotnet/corefx/issues/4571 https://github.com/dotnet/corefx/issues/5782 https://msdn.microsoft.com/en-us/library/ms971499.aspx # Proposal We will bring back DbProviderFactories in CoreFx. But instead of register/read the configuration from machine.config, we will provide a code based configuration. This will allow application writer to hook this with any configuration mechanism. ## Contract Changes We will bring back DbProviderFactories.GetFactory functions in V1 contract which will support .Net 4.6.2. And add ""RegisterFactory"" functions in V2 contract to support .Net vNext. (version after 4.6.2) For portability, we will bring ""RegisterFactory"" into .Net vNext and should work side by side with file config behavior. e.g code based config will override file based config). Portable library (such as ORM), can start using GetFactory and target it for .Net 4.6.2. If this library used in .NET 4.6.2 , GetFactory will return factory which defined in machine/app configs. Corefx application which used this portable library can register their factory using ""RegisterFactory"". Once we release ""RegisterFactory"" into .Net vNext, The behavior will be work seamless in both frameworks. ``` C# namespace System.Data.Common { public static class DbProviderFactories { // V1 -- Supported by .NET Framework 4.6.2 (the upcoming version) public static DbProviderFactory GetFactory(string providerInvariantName); public static DbProviderFactory GetFactory(DbConnection connection); // V2 -- Supported by .NET Core 1.0 and by .NET Framework vNext (version after 4.6.2) public static void RegisterFactory(string providerInvariantName, DbProviderFactory factory); public static IEnumerable GetFactoryProviderNames(); } } ``` ## DbProviderFactories CoreFx Implementation ``` C# public abstract class DbProviderFactories { internal static readonly Dictionary> _configs = new Dictionary>(); public static DbProviderFactory GetFactory(string providerInvariantName) { ADP.CheckArgumentLength(providerInvariantName, nameof(providerInvariantName)); if (_configs.ContainsKey(providerInvariantName)) { return _configs[providerInvariantName](); } throw ADP.ConfigProviderNotFound(); } public static DbProviderFactory GetFactory(DbConnection connection) { ADP.CheckArgumentNull(connection, nameof(connection)); return connection.ProviderFactory; } public static void RegisterFactory(string providerInvariantName, DbProviderFactory factory) { ADP.CheckArgumentNull(providerInvariantName, nameof(providerInvariantName)); ADP.CheckArgumentNull(constructorDelegate, nameof(constructorDelegate)); _configs[providerInvariantName] = factory; } public static IEnumerable GetFactoryProviderNames() { return _configs.Keys.toArray(); } } ``` ## Usage For CoreFX application, You need to register your provider factory during startup of your application. ``` C# public static void Startup() { //SqlClientFactory is a singleton factory DbProviderFactories.Add(""System.Data.SqlClient"", SqlClientFactory.Instance); //You can use other factory which not singleton. DbProviderFactories.Add(""System.Data.OtherProvider"", new OtherProviderFactory()); } ``` # Progress I have created initial commit on my branch to inspect what are the changes needed. https://github.com/kkurni/corefx/commit/68380b3451d3ba0ce9646119101e9b4309f09d68 " 6477 area-System.Linq Order of execution for Enumerable.Join differs between coreclr and net451 "Order of execution for Enumerable.Join differs between coreclr and net451.

" 6485 area-System.Runtime Add parameterless overloads of TrimStart/TrimEnd I propose we add parameterless overloads of `TrimStart`/`TrimEnd` for the String class. # Rationale - We have a parameterless `Trim` [method](https://msdn.microsoft.com/en-us/library/t97s7bs3%28v=vs.110%29.aspx), so it's best to do this for symmetry. - We can avoid array allocations every time the method is called, e.g. `TrimStart()` would no longer transparently allocate an array. We can avoid this with `TrimStart(Array.Empty())`, but that's besides the point. - With the [current implmementation](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/String.cs#L1366) in CoreCLR, it would be relatively trivial to implement. Just add this to the class: ``` csharp public string TrimStart() => TrimHelper(TrimHead); public string TrimEnd() => TrimHelper(TrimTail); ``` - Perhaps this is just me, but when I first came across the `TrimStart(params char[])` overload (as a beginner to C#), I wasn't even aware that you could leave a `params` method empty. I just assumed that the functionality I was looking for wasn't available, and ended up making my own helper method. # Proposed API ``` csharp namespace System { public class String { // New methods public string TrimStart(); public string TrimEnd(); } } ``` 6486 area-System.Net Support setting outgoing interface for multicast on Socket The desktop framework and mono support setting the interface used for outgoing multicast traffic by passing the interface index as a value for the MulticastInterface SocketOption. ``` socket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.MulticastInterface, IPAddress.HostToNetworkOrder(interfaceIndex)) ``` On Windows this is an acceptable value for IP_MULTICAST_IF, see [msdn IPPROTO_IP](https://msdn.microsoft.com/en-us/library/windows/desktop/ms738586%28v=vs.85%29.aspx). On non-Windows platforms the request should be translated to pass an ip_mreqn as the IP_MULTICAST_IF value, see [man ip](http://man7.org/linux/man-pages/man7/ip.7.html).

" 6500 area-System.Net Release pinned buffers correctly for WinHttpHandler, WinHttpWebSocket Both WinHttpHandler and WinHttpWebSocket use pinned buffers for receiving and sending data. The pinned GCHandle was being freed during the dispose of the WinHttpHandler or WinHttpWebSocket objects. The problem is that the buffer should not be unpinned until the async operation is done. It's possible for any async operation to be in flight (and where native code uses the buffer) when the object is explicitly or implicitly disposed. This fix moves the ownership of the pinned GCHandle to their respective state objects (WinHttRequestState, WinHttpWebSocketState). These objects are strongly rooted and are not released until all async operations are completed and the WinHTTP handles are fully closed. That makes these state objects a safe place to own and free the pinned buffers.

Typically, the algorithm is initialized with some starting state. It's then presented with a sequential stream of identically-typed elements. For each arbitrarily-chosed block of elements, the algorithm may either modify the starting state or produce an incremental block as part of an output stream, or both, depending on the algorithm in question. Algorithms which follow this pattern include compression/decompression, encryption/decryption and hashing. In the BCL, these algorithms are typically modeled as wrappers of System.IO.Stream. For instance, you write normally to a file by using a FileStream. But if you wrap this FileStream with a GZipStream, then writing to the wrapper will cause the file to be compressed. This is incredibly convenient when your use case exactly matches the functionality in the BCL. Where it falls apart, though, is for non-matching use cases. For instance, let's say you want to compress a Stream while reading it. This simply isn't supported directly today. The only way to make use of GZipStream in this scenario is by creating two adapters -- one that reads from the original stream and writes to the GZipStream, and one that intercepts the writes out of the GZipStream and puts a pull interface back on top of it. If the GZip functionality in the BCL were also exposed in a more primitive form -- for instance, something like the [Compressor interface in Hadoop](http://hadoop.apache.org/docs/current/api/org/apache/hadoop/io/compress/Compressor.html), it would be much easier to implement custom scenarios on top of the base functionality. Given a sufficiently general abstraction for the initialize/process next block/finish set of operations, it might even be possible to reduce the amount of per-algorithm code that exists simply to interface with Stream. Unfortunately, the CoreCLR footprint appears to be going backwards in this regard. As an example, the HashAlgorithm class previously had methods for TransformBlock and TransformFinalBlock, but these have removed. The only way to make use of HashAlgorithm in a streaming fashion is to go through the pain of exposing the data as a (blocking) Stream, which can be extremely inconvenient. 6519 area-System.Net Fix SocketException error codes and messages on Unix "SocketException's public ctor takes an int, which it treats as both a SocketError and the native error code, passing it down to the base Win32Exception to get the platform-specific message for the error. However, SocketError is only the same as the native error code on Windows; on Unix, a translation is required, but that translation is missing. As a result, every SocketException thrown from System.Net.Sockets on Unix comes out with an unhelpful message ""Unknown error 12345"", where 12345 is the value for the SocketError, and the base native error code is set inappropriately as the SocketError's value rather than as the real errno value. This change puts a reverse mapping in place, such that the SocketError provided to SocketException is then translated back (as best as possible) into the underlying platform's native error code, which is then both stored on the base exception and used to get the appropriate platform-specific error message. So, for example, rather than getting an error like: ``` System.Net.Sockets.SocketException: Unknown error 10047 ``` you now get an error like: ``` System.Net.Sockets.SocketException: Address family not supported by protocol ``` Additionally, several SocketErrors map to errno values that weren't included in our Interop.Errors enum. I've added them. And, SocketException had dead code in the form of an ""internal SocketException(EndPoint endPoint)"" ctor that was never used. As a result, the private _endPoint field was always null, and the Message property would always just return base.Message. I've removed the constructor, the field, and the Message property override. SocketException also had an ErrorCode property in the implementation that wasn't in the ref contract; I've removed it from the implementation, too. cc: @davidsh, @pgavlin, @ericeil Fixes https://github.com/dotnet/corefx/issues/5849 " 6522 area-Infrastructure Update netci and run-test to use the IgnoreForCI trait in Jenkins Updates the netci.groovy and runtest.sh files to pass `-notrait Category=IgnoreForCI` to `build.cmd` and `run-test.sh` in Jenkins so that we can disable tests from running when they're being run in Jenkins. @dotnet-bot test ci please @Priya91 would you mind checking (or showing me how to check) that the generated jobs are correctly passing the -notrait / WithoutCategories? replaces part of #6145 6523 area-System.Net Support setting outgoing interface for multicast on Socket Fix https://github.com/dotnet/corefx/issues/6486 pal_networking: support specifying the network interface for outgoing multicast traffic via SocketOptionName.MulticastInterface on non-Windows platforms The interface for outgoing multicast traffic can be set as follows: socket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.MulticastInterface, IPAddress.HostToNetworkOrder(interfaceIndex)) 6533 area-System.Reflection CustomAttributeDecoder should cache and reuse common arguments to avoid boxing Currently, in CustomAttributeDecoder.DecodeArgument, we'll re-box small integers, true and false every time they're encountered.

This is error hiding. `Add()` and `Remove()` don't allow the store to be not opened in advanced. There's no way to check the store is opened. Something like this: ``` void traverseCerts( X509Store store ) { var allCerts = store.Certificates; //traverse allCerts } ``` cannot even check the store is opened - it gets a collection anyway, maybe empty and it's empty maybe because the store is not opened or because the store is indeed empty. The same behavior is on desktop. This is extremely inconvenient. A `IsOpened` property is surely needed. Also `Certificates` getter likely needs to throw an exception if the store is not opened in advance.

This is not necessarily true; we need to allow other threads to continue to issue reads until they've actually read all data. This is resulting in assert failures (#6506) and is a likely cause of erroneous OperationAborted failures (#5750). It's not clear to me what value the EOF handling is providing currently; currently, aside from erroneously shutting down the queue, the only difference from the normal read event logic is that we also unregister from read events. Since we no longer are able to free handles, etc., on unregistration, it's not clear that we get any benefit from unregistering an event we'll probably never receive again. This change therefore simply removes this logic. Fixes #6506.

The goal of this is to get the open tests universally better than the ToF tests so that we can turn the ToF tests off for ProjectK runs and save us all a lot of headache diagnosing test failures from potentially outdated tests. For System.Runtime, we're missing 2020 lines of coverage. Our total line coverage for Open vs. ToF is 69.7%. However, this includes some data points that might not be relevant to the library being tested so the real coverage is likely lower. To fulfill the uncovered lines we would need to either create new tests for them or port 56 ToF tests to the open.

" 6584 area-System.Net Make WebUtility.UrlDecoder a struct Follow-up from #6538: basically the same changes except for the `System.Buffers`-related ones, since we wanted to avoid a dependency on that for the package `WebUtility` lives in. cc @stephentoub 6589 area-System.Diagnostics Add a production assert facility It is possible to use `Debug.Assert` in `DEBUG` builds to assert runtime conditions. The Base Class Library currently has no way to assert something in non-debug builds. That's a pity because in many applications it is a prudent choice to leave (cheap) assertions enabled in production. Many projects do not wish to make use of Code Contracts. It seems heavy-weight to pull in Code Contracts just to have an assert method. Please add a release build assert to the BCL. Here are some naming proposals: ``` Debug.ReleaseAssert(...) Assert.Debug.IsTrue(...); Assert.Release.IsTrue(...); ``` Another thing that makes `Debug.Assert` unusable in production is that it pops up a dialog box or crashes the process. This is inappropriate with ASP.NET where you normally want to simply abort the current HTTP request and let the process live. It's also inappropriate in any form of client-side GUI app. Frankly, the Abort-Retry-Cancel dialog that pops up is ... not very nice. Most apps are not overly concerned with state corruption. A `FailFast`-like approach is not desirable. Therefore, the new assert functions should merely throw an `AssertFailedException`. If the developer chooses to add a catch-all top-level handler to his request processing then so be it. The assertion failure exception will contain the stack trace pointing to the location of the error. It will be fairly easy to debug the assertion failure from logging output. The new assertion facility should _not_ be configurable to do something else (e.g. log and `FailFast`). Developers should be able to rely on the exact exception throwing behavior outlined above. When I see a production assert in foreign code I want to know what it does. I don't want the possibility that some developer-provided hook is called. Another benefit is that the whole ecosystem can standardize on this `AssertFailedException` class. All tools and testing frameworks can learn to understand it. The `AssertFailedException` is useful by itself, for example to signify unreachable code: ``` switch (...) { case: return 1; default: throw new AssertFailedException(); } ``` This would _not_ be possible with `Assert(false)` because the compiler must know that all paths return a value or throw. To help with this scenario, we could as a `class UnreachableException : AssertFailedException`. Now, tools can standardize on that one as well. When Resharper generates a `switch` it can use this exception type, for example. In this issue I have outlined the approach that I have used over 5 years in a 100 kLOC codebase. I found it to work very well. 6591 area-System.IO Fix System.IO.FileSystem handling of symlinks "We've visited this topic a few times... hopefully this is the last. We previously misunderstood some of how Windows handles symlinks, leading us to make some invalid choices on Unix. This addresses those issues. For the most part with this commit, we now match Windows behavior on Unix wherever possible, while also trying to do something sensible on the Unix side. The only notable difference now comes into play for broken symlinks, due to a fundamental difference between symlinks on Windows and Unix: on Windows, a symlink is created as either a file or directory symlink and thus .NET can tell which it is even if it's broken... on Unix, a symlink only stores a path to its target, so when it's broken, there's no information about whether it's intended to be a file or a directory. As a result, we fall back to always treating it as a file. To help highlight the behavior, consider this set up: - TargetDir - normal directory - LinkDir - a symlink to TargetDir - BrokenLinkDir - a symlink for a directory that's been deleted - TargetFile.txt - normal file - LinkFile.txt - a symlink to TargetFile.txt - BrokenLinkFile.txt - a symlink to a file that's been deleted - ReadonlyTargetFile.txt - a file attributed as readonly - LinkReadonlyFile.txt - a link to ReadonlyTargetFile With that, this program: ``` C# using System; using System.IO; using System.Linq; using static System.Console; class Program { static void Main() { WritePathDetails( ""TargetDir"", ""LinkDir"", ""BrokenLinkDir"", ""TargetFile.txt"", ""LinkFile.txt"", ""BrokenLinkFile.txt"", ""ReadonlyTargetFile.txt"", ""LinkReadonlyFile.txt""); } static void WritePathDetails(params string[] paths) { foreach (string path in paths) { WriteLine($""Path : {Try(() => Path.GetFileName(path))}""); WriteLine($""File.Exists : {Try(() => File.Exists(path))}""); WriteLine($""FileInfo.Exists : {Try(() => new FileInfo(path).Exists)}""); WriteLine($""Dir.Exists : {Try(() => Directory.Exists(path))}""); WriteLine($""DirInfo.Exists : {Try(() => new DirectoryInfo(path).Exists)}""); WriteLine($""FileInfo.Length : {Try(() => new FileInfo(path).Length)}""); WriteLine($""FileStream.Length : {Try(() => { using (var fs = File.OpenRead(path)) return fs.Length; })}""); WriteLine($""FileInfo.Attributes : {Try(() => new FileInfo(path).Attributes)}""); WriteLine($""DirInfo.Attributes : {Try(() => new DirectoryInfo(path).Attributes)}""); WriteLine($""Dir.Enumerate : {Try(() => Directory.EnumerateFiles(path).Count())}""); WriteLine($""DirInfo.Enumerate : {Try(() => new DirectoryInfo(path).EnumerateFiles().Count())}""); WriteLine(); } } static object Try(Func func) { try { return func(); } catch (Exception e) { return $""{e.GetType().Name}: {e.Message}""; } } } ``` now outputs the following:

Interesting things to notice: - The only meaningful differences are for the ""Broken"" cases. - On Windows, symlinks are empty files and thus have 0 length. On Unix, they contain a path and thus have a length proportional to that path. - On Windows, files sometimes include an Archive attribute. This is Windows-specific and we don't include that attribute on Unix.

This PR attempts removes assertions about relation between the length and the data pointer. cc: @stephentoub @vijaykota 6663 area-System.IO Provide a version of Stream.Read that reads as much as possible I believe one of the most common mistakes when using `Stream.Read()` is that the programmer doesn't realize that `Read()` may return less data than what is available in the `Stream`. And even for programmers who are aware of this, having to write the same loop every single time they want to read from a `Stream` is annoying. So, my proposal is to add the following methods to `Stream` (mirroring the existing `Read` methods): ``` c# public int ReadAll(byte[] buffer, int offset, int count) public Task ReadAllAsync(byte[] buffer, int offset, int count) public Task ReadAllAsync(byte[] buffer, int offset, int count, CancellationToken cancellationToken) ``` Each `ReadAll` method would call the corresponding `Read` method in a loop, until the `buffer` was filled or until `Read` returned 0. Questions: - Is there a better name than `ReadAll`? - These methods would work as well if they were extension methods. Should they be? - Very similar functionality is already exposed through `BinaryReader.ReadBytes()`. Why doesn't it have `async` version? 6666 area-System.Net On OSX, throw PlatformNotSupportedException from Socket.ReceiveFrom, … …ReceiveMessageFrom, etc., if called on a dual-mode socket. OSX does not provide IPv4 packet information for dual-mode sockets, so these APIs cannot be made to behave consistently when used on dual-mode sockets.

So, you need: - To be running on OSX (ElCapitain in my case) - The watched folder must be in the temp folder returned by `Path.GetTempPath()` Here's the code to reproduce: ``` csharp // This works (update the username): // var folder = Path.Combine(""/Users/victorhurdugaci/temp"", Guid.NewGuid().ToString()); // This fails: var folder = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString()); Console.WriteLine(folder); Directory.CreateDirectory(folder); using (var watcher = new FileSystemWatcher(folder)) { watcher.Created += (s, e) => { Console.WriteLine(""### Triggered""); }; watcher.EnableRaisingEvents = true; File.WriteAllText(folder + ""/f2"", """"); Console.WriteLine(""waiting...""); System.Threading.Thread.Sleep(10000); } ``` With the temp folder, it only prints ``` waiting... ``` With the user folder, it prints: ``` ### Triggered waiting... ``` Not sure if it's something special about the path characters or length. On my machine, the generated temp folder looks like `/var/folders/x4/h490d6xs4mndqfg5sk231_mw0000gn/T/1cc8944d-b218-4f95-8dd0-ea208fb9b9b7` `System.IO.FileSystem.Watcher` version is `4.0.0-rc2-23826` " 6676 area-System.Net Need more tests for non-DualMode socket usage There is a lot of coverage of DualMode socket send/receive operations that does not have corresponding coverage for non-DualMode sockets.

Unfortunately that breaks code on CoreCLR that uses reflection. The issue is that a netstandard library can reference types in that assembly even if it’s not used at runtime. It’s part of PCL 259 as well. So if I have an app (or unit test in this case) that runs on CoreCLR and uses reflection against a type in that library, I get a FileNotFoundException and it cannot load the types. Here's an example from Rx.NET ``` ReactiveTests.Tests.ObservableEventsTest.FromEventPattern_Reflection_Instance_InvalidVariance [FAIL] Expected InvalidOperationException threw FileNotFoundException. Stack trace: at System.Reactive.ReflectionUtils.GetEventMethods[TSender,TEventArgs](Type targetType, Object target, String eventName, MethodInfo& addMethod, MethodInfo& removeMethod, Type& delegateType, Boolean& isWinRT) at System.Reactive.Linq.QueryLanguage.FromEventPattern_[TSender,TEventArgs,TResult](Type targetType, Object target, String eventName, Func`3 getResult, IScheduler scheduler) at System.Reactive.Linq.QueryLanguage.FromEventPattern_[TEventArgs](Object target, String eventName, IScheduler scheduler) at System.Reactive.Linq.QueryLanguage.FromEventPattern[TEventArgs](Object target, String eventName) at System.Reactive.Linq.Observable.FromEventPattern[TEventArgs](Object target, String eventName) at ReactiveTests.Tests.ObservableEventsTest.<>c.b__9_0() in C:\Users\oren\source\git\reactive-extensions-private\Rx.NET\Source\Tests.System.Reactive\Tests\Linq\ObservableEventsTest.cs:line 280 at Microsoft.Reactive.Testing.ReactiveAssert.Throws[TException](Action action) Expected: True Actual: False ``` The unit test is a `netstandardapp1.5` and the library under test is a `netstandard1.0` lib. It just so happens that the code references types in that `System.Runtime.InteropServices.WindowsRuntime` package. This worked (and the tests passed) in dnx. Note that I don't necessarily expect WinRT functionality to work, but it seems critical that the file exists and is copied to all runtimes. Xamarin had this issue at one point too as they didn't generate this façade assembly. They finally did even if it was mostly no-ops. 6685 area-System.Text Proposal: Regex Repetition Syntax Enhancement "# The Issue If we want to match a list of any kind in regex, we currently have to make certain compromises. For example, say we wanted to match a list of names, such as: `Anna,Bob,Charlie` (a more complex example would be a list of phone numbers, or url's, so imagine the regex is potentially long and complex). We could try: ``` ((Anna|Bob|Charlie),)+ ``` However that doesn't match our original text as it requires a final `,` to match. | Text | Should match | Matches | | --- | --- | --- | | `""Anna,Bob,Charlie""` | yes | no **(wrong)** | | `""AnnaBob,Charlie""` | no | no | We could try: ``` ((Anna|Bob|Charlie),?)+ ``` But this will wrongly match items without the separator, which is probably not what the user wants: | Text | Should match | Matches | | --- | --- | --- | | `""Anna,Bob,Charlie""` | yes | yes | | `""AnnaBob,Charlie""` | no | yes **(wrong)** | Currently the only way to achieve this is through the duplication of the list-item regex group: ``` (Anna|Bob|Charlie)(,(Anna|Bob|Charlie))* ``` Which is a pain when the match is long like a phone number or a url, and if you update one part you have to remember to copy the changes to the other one. It also gets tricky if say you wanted it to match from 0 to 20 items, you'd have to do it like this: ``` ((Anna|Bob|Charlie)(,(Anna|Bob|Charlie)){0,19})? ``` The only way to somewhat avoid this is to put that regex part into a variable and use the variable twice to construct the regex, but this relies on the host language, still creates a longer than necessary regex, and matches an extra redundant matching group which the user then has to manually group with the first in the host language. # Proposal A more useful approach could be to use some repetition separator syntax. Regex already has repetition quantifiers like `+`, `*`, `?` and also `{m,n}`. The last one could be enhanced to specify an optional third parameter as a repetition-separator group: ``` (Anna|Bob|Charlie){0,20,(,)} ``` Since it can contain any valid regex syntax, it should always be enclosed inside a group, and it behaves like any normal group. Just like in normal usage, the quantifier limit values can be missing entirely: ``` (Anna|Bob|Charlie){,,(,)} ``` And if we only wanted to specify the separator: ``` (Anna|Bob|Charlie){(,)} ``` This would allow infinite repetition, equivalent to using the `*` or `{,}` quantifiers. | Text | Should match | Matches | | --- | --- | --- | | `""Anna,Bob,Charlie""` | yes | yes | | `""AnnaBob,Charlie""` | no | no | We could then easily enhance it to, for example, allow spaces after each comma: ``` (Anna|Bob|Charlie){(, *)} ``` This is much shorter and more readable than any existing alternatives, and produces a match result with all the correct values in the same matching group. The flow would look like this: ![regex separator flow](https://cloud.githubusercontent.com/assets/785247/13548375/98ba6ba2-e2f7-11e5-8396-38e6d0a68265.png) # Other examples These examples have been kept short for readability reasons and could need fine-tuning to work in all cases. | Description | Regex | | --- | --- | | Phone number lists | `(\(?\d{3}\)?-? *\d{3}-? *-?\d{4}){(, *)}` | | Versions names (""3.7.15"") | `(\d){(\.)}` | | Html class attribute | `class=""\s*(?\S+){(\s+)}\s*""` | | Html class attribute (alternative) | `class=""(\s*){(?\S+)}""` | | Mathematical calculations (""7.5 \* 2 + 10"") | `(\d+(\.\d)?([Ee]\d)?){( *[+-*/] *)}` | | Name parts (""Johann Wolfgang von Goethe"") | `^(?\S+){( )}$` | | Natural language (notice the nested repetitions) | `winners are (?(?\S+){1,,( )}){( then )}` | | Time matching (""03:15"", ""23:59:59"") | `(\d\d):(\d\d){1,2,(:)}` | | Javascript object notation | `[{] *(?[a-zA-Z_]\w*) *: *(?""[^""]*""|\d+(\.\d*)?([Ee]\d*)?|...other.types..){( *, *)} *[}]` | # Special Case In certain use cases a final optional separator match is also desirable. For example, in C# the collection initializer syntax allows for an optional final `,`: ``` C# var names = new List { ""Anna Alyson"", ""Bob Borton"", ""Charlie Cob"", }; ``` For this we could further enhance the syntax so that if the separator-group has a `+` after it, it can have an optional final match (the separator-group would not allowed to have any other quantifiers, however sub-groups can). The regex would look like this: ``` [{]\s*(?""[^""]*""){(\s*,\s*)+}\s*[}] ``` The new flow would then look like this: ![regex separator flow 2](https://cloud.githubusercontent.com/assets/785247/13548546/8badb2b2-e2fb-11e5-9d74-3860cc64ec2a.png) " 6689 area-System.Reflection Type conflict with BindingFlags "Type/namespace conflict with BindingFlags and `System.Reflection.TypeExtensions` renders code unable to compile.

" 6695 area-System.Runtime Adding an Array.Fill method ## Background At the moment, there's no built-in way to fill an array with a particular value in .NET. You'd have to hand-roll your own extension method, like this: ``` csharp public static void Fill(this T[] array, T value) { for (int i = 0; i < array.Length; i++) array[i] = value; } ``` While this may be the most obvious way, it is not necessarily the most efficient. For example, we could specialize to `memset` if the array was a byte array, or use an algorithm where we fill the beginning of the array and [double the number of elements copied each time](http://stackoverflow.com/a/13806014/4077294). To increase the efficiency of code doing this and prevent people from reinventing the wheel, I propose we add a static `Fill` method to the `Array` class that does this. ## Proposed API ``` csharp public class Array { public static void Fill(T[] array, T value); public static void Fill(T[] array, int offset, int count, T value); } ``` 6698 area-System.Net Short-circuit for strings in WebUtility.UrlEncode This is a follow-up on #6543 for `UrlEncode`. It has separate implementations for making passes over the strings/byte arrays, so (I haven't tested this yet) there should be no performance loss. cc @stephentoub 6700 area-System.Net Add performance tests for WebUtility You asked for perf tests in #6698, so here they are. cc @davidsh **note:** I'm having trouble compiling the tests locally because of some error with `SafeProcessHandle` (probably unrelated), so I'll fix any errors if they pop up in CI. 6701 area-System.Reflection Propose, API change: DispatchProxy instantiation The current API for instancing the DispatchProxy is counter intuitive name- and usage-wise. Especially when injecting dependencies into the proxy. ``` cs public static T Create() where TProxy : DispatchProxy ``` Currently `Create` will return the proxied instance of T, which then oddly needs to be cast to the TProxy type in order to inject any dependencies into the proxy instance itself: ``` cs ISomeServiceInterface proxiedInstance = DispatchProxy.Create(); var actualProxy = proxiedInstance as MyProxy; actualProxy.MyDependency = dependency; ``` Instead consider returning the proxy instance itself, and add a property in order to retrieve the proxied instance to allow following usage: ``` cs MyProxy proxy = DispatchProxy.Create(); proxy.MyDependency = dependency; IServiceInterface proxiedInstance = actualProxy.ProxiedInstance; ``` 6702 area-Infrastructure Errors

It would be nice if we could just provide a `MemoryFill` method that was equivalent to memset/the initblk opcode. ## Proposed API ``` csharp public static class Buffer { public unsafe static void MemoryFill(void* pointer, byte value, long count); public unsafe static void MemoryFill(void* pointer, byte value, ulong count); } ``` (revision: Changed the wording from `MemorySet` to `MemoryFill` since that sounds less awkward) 6718 area-System.Security Remove X509Certificates workaround after updating packages After we update to package version 23908 or later we need to remove the project reference workaround I added to address lack of support for netstandard1.3. See https://github.com/dotnet/corefx/pull/6717 & https://github.com/dotnet/corefx/pull/6713. I added a workaround to System.Net.Http.WinHttpHandler, System.Net.Security, and System.Net.WebSockets.Client. All of these assemblies were targeting NETStandard1.3 and using X509Certificates. I had to replace the package reference with a project reference to the reference assembly temporarily because the assembly was missing from the package. I temporarily added dependencies on other crypto contracts (required to make package validation see a full closure). Once we update packages, replace these with a single reference to the X509Certificates package and remove the project reference from the csprojs. 6720 area-System.IO Add better failure messages when trying to create a named pipe on non-Windows "Trying to create a cross-machine named pipe or a named pipe with a name that includes characters that aren't valid as a filename throws a `PlatformNotSupportedException`.

This handler is not storing HttpOnly cookies in the cookie collection it creates. Should it store HttpOnly cookies by default as well? It appears this issue has a history. The comment in code (see [HttpClientHandler.cs 462-473)](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/netcore50/System/Net/HttpClientHandler.cs#L462-L473) explains the history of this quirk.

But this clearly does not apply to all platforms (e.g. Linux). To play with the issue, see this example app: https://gist.github.com/natemcmaster/e51aa33cf77416772afc This creates a simple server that response with 2 cookies, on HttpOnly and the other not.

Since .NET does not yet support multiple return values, this is commonly represented as an `ArraySegment`, where T is the type of the element contained in the array. Unfortunately, the System.IO namespace does not have overly sophisticated support for `ArraySegments` (aside from the recently-added `TryGetBuffer` for `MemoryStream`), forcing people who use them to 'unravel' them like this: ``` csharp stream.Write(segment.Array, segment.Offset, segment.Count); ``` I propose adding convenience methods to the existing System.IO APIs that will make this less verbose, and prevent accidents like e.g. the programmer mixing up `Offset` and `Count`. ## Proposed API ``` csharp namespace System.IO { public class BinaryReader : IDisposable { public int Read(ArraySegment buffer); public int Read(ArraySegment buffer); } public class BinaryWriter : IDisposable { public void Write(ArraySegment buffer); public void Write(ArraySegment buffer); } public class MemoryStream : Stream { public MemoryStream(ArraySegment buffer); public MemoryStream(ArraySegment buffer, bool writable); public MemoryStream(ArraySegment buffer, bool writable, bool publiclyVisible); } public class Stream : IDisposable { public int Read(ArraySegment buffer); public Task ReadAsync(ArraySegment buffer); public Task ReadAsync(ArraySegment buffer, CancellationToken cancellationToken); public void Write(ArraySegment buffer); public Task WriteAsync(ArraySegment buffer); public Task WriteAsync(ArraySegment buffer, CancellationToken cancellationToken); } public abstract class TextReader : IDisposable { public int Read(ArraySegment buffer); public int ReadBlock(ArraySegment buffer); public Task ReadBlockAsync(ArraySegment buffer); } public abstract class TextWriter : IDisposable { public void Write(ArraySegment buffer); public Task WriteAsync(ArraySegment buffer); public void WriteLine(ArraySegment buffer); public Task WriteLineAsync(ArraySegment buffer); } } ``` 6742 area-Infrastructure Arch Linux: Build.sh Managed Is Broken With Wrong Paths "``` $ ./build.sh x64 release Unsupported Linux distribution 'arch' detected.

There isn't a good mapping between OpenSSL errors and most of the errors in SecurityStatusPal. As a result, with the current set up, important information about errors that occurred is getting lost and translated into meaningless information by the time it makes it out to the developer, making it difficult to diagnose the cause of a failure. This commit allows the original exception behind a failure to be passed through the PAL layer, such that when an exception is eventually thrown, the Unix implementation can choose to use the original exception rather than translating the error code. For example, instead of: ``` System.Security.Authentication.AuthenticationException : A call to SSPI failed, see inner exception. ---- Interop+OpenSsl+SslException : Operation failed with error - 12. ``` (where ""12"" is the number that ends up getting used for all failures, as the numerical value of SecurityStatusPal.InternalError), we now get: ``` System.Security.Authentication.AuthenticationException : A call to SSPI failed, see inner exception. ---- Interop+OpenSsl+SslException : SSL Handshake failed with OpenSSL error - SSL_ERROR_SSL. -------- Interop+Crypto+OpenSslCryptographicException : error:140740B5:SSL routines:SSL23_CLIENT_HELLO:no ciphers available ``` Commit (2). Use ExceptionDispatchInfo in SslStream. Currently in SslStream, exceptions get captured and then later thrown with ""throw exception;"". This causes their stack traces to get overwritten, losing information about where the exception actually came from. This commit changes these locations to use ExceptionDispatchInfo instead, enabling the stacks and Watson bucket information to be preserved.

While it is common that certain members are not available in a supertype it certainly feels very strange that a property just get's renamed without any semantic change. You argued: ""We’ve decided to go with having a Length property instead of Count because we see ImmutableArray as a replacement for regular arrays. This makes it easier to port existing code. It also makes the design a bit more self-contained."" But since most other collections besides the array come with a Count property, the chances are very hight that with using the Length property you keep on switching between those properties on every larger refactoring. It would be nice if you could just add the Count property if possible. By that users that more likely switch between covariant access and direct access to the immutable array (instead of switching between mutable and immutable) can just stick with a property that doesn't break code.

But two threads executing **System.Diagnostics.Trace.Listeners.Remove(""Default"")** at the same time can run into each other. The problem is that several operations (like Remove(string)) are built on top of enumerating the collection, and enumerating the collection will neither lock it nor make a copy of it. It's possible to squint and say ""but it is thread-safe in that its internal state can't be corrupted via multiple simultaneous mutation"", but I don't think that's consistent with the way that most people think of thread-safety.

I created this issue to improve documentation (and perhaps tooling) for the general issue. Banana Unix is the term used by @jasonwilliams200OK in https://github.com/dotnet/cli/issues/1532 for some platform that doesn't support coreclr yet. This could be the next version of Debian or it may just as well be a custom built linux system for an embedded device. Some concrete questions: What are the minimal parts that need to be built for supporting a new platform? In what repos are they? And with which commands can they be built? Can these bits be built on an existing supported platform? Or does the build have to be done on the new platform? If the latter, is there any bootstrapping needed (e.g. get a first-stage core runtime to build the one for the new platform)? How is this done? \cc @jasonwilliams200OK @ellismg @stephentoub 6771 area-System.Net .NET Core Http Support So I wrote some test apps in C against LibUV and Libcurl api to get a feel of what’s powering Kestrel and HttpClient and while I can say that both libraries provide a very elegant and straightforward callback API I can’t help but raise the question: Why do we need these in .NET Core? Sure, LibUV makes perfect sense for NodeJS as a cross-platform abstraction layer for sockets, files, timers, thread pool, mutex.. but in .NET Core all these services are already inherently offered cross-platform by CoreFX. Simply put what does uv_accept / uv_read_start provide that the Socket.AcceptAsync/Socket.ReceiveAsync lack? As for Libcurl, again great library for Native developers but what’s in it for Managed developers? Furthermore, from what I see we are not using the high performance event driven curl_multi_socket_action interface with timeout callback and in any case why not just port the full .NET HttpWebRequest to use .NET Core cross-platform async socket interface and have a consistent implementation across both Windows / *Unix down to the socket level? There is also a potential problem if someone wants to use a third-party native library (PInvoke) that depends on some version specific build of one of these; I mean how can you load multiple versions of LibUV or Libcurl in the same .NET process and why does the FW need to take part of any potential conflict that might occur? Lastly, I think it's very important to include an equivalent of HttpListener for both Windows and *inux in CoreFX Because: 1. There are probably existing applications that use HttpListener interface that now can’t be ported to .NET Core and run on both Windows and *inux as is. 2. Experience shows that web application framework’s (including ASP.NET) are highly opinionated. Some people need/like the “Application model” some just want access to an Http interface. In my opinion it would be a mistake not include a low-level http server in CoreFX as part of the standard library as the case in Go and NodeJS. Kestrel is great but it’s an ASP.NET server subsystem not a .NET CoreFX library. 6772 area-System.Net Fix IAsyncResult.AsyncState cast to ExceptionDispatchInfo I had this change locally but neglected to include it as part of my SslStream errors fix-up PR yesterday.

The implementation is generic, and should support all calendars. ### Todo There are some issues to be investigated: - [x] JapenseLunisolarCalendar is not supported. This is because the implementation calculates that the `MaximumCalendarYearInEra(new JapaneseLunisolarCalendar(), 3)` is 1, not as 64 (IIRC) expected. This can be fixed by changing the code from `return calendar.GetYear(calendar.ToDateTime(1, 1, 1, 0, 0, 0, 0, era + 1).AddDays(-1)) + 1;` to `return calendar.GetYear(calendar.ToDateTime(1, 1, 1, 0, 0, 0, 0, era + 1).AddMonths(-1)) + 1;`, but this reduces the versatility of existing tests. - [ ] `GetDayOfWeek_Invalid` should not be tested for Lunar and lunarsolar calendars, as the method doesn't throw on these calendars. There is no way in corefx to check if a calendar is lunarsolar - [ ] `GetEra_Invalid` throws an exception for most calendars, but not HebrewCalendar, TaiwanLunisolarCalendar and JapaneseLunisolarCalendar. Maybe this is a similar cause from the previous point ### Further ideas Some further ideas that are nice but not so important - Test each year, and invalid months outside the max and min month in each year - Test each month, and invalid days outside the max and min day in each month /cc @tarekgh 6778 area-System.Runtime [corert] Define and implement Marshal.GetLastWin32Error for Linux systems System.Private.Uri is using Marshal.GetLastWin32Error, when compiling it as aot (corert netstandard13aot) for Linux it complain about Marshal.GetLastWin32Error is not implemented.

Without it, the only way to close a file is to delete the `File` object which requires coping with nulls, a thing F# tries very hard to avoid. Explicitly closing a file is often necessary on Windows due to its mandatory file locking semantics. For example, you cannot typically move or a file to another directory while a `File` object is open for writing on that file. Lacking a `Close()` method, single-assignment code such as this: ``` open System.IO let file = File.Create(""myfile"", ...) ... do stuff with file file.Close() ... do something with myfile on disk ``` must be rewritten to use a mutable `file` object: ``` open System.IO let mutable file = File.Create(""myfile"", ...) ... do stuff with file file <- null ... do something with myfile on disk ``` Although that looks like a simple fix, now all the F# code dealing with `file` has to check for `null` before using the value, a very un-F# style of coding.

It would allow .NET to deal with any Physics-based situation in an intuitive and easy way. What I am proposing here might also be adapted to other not-related-to-Physics requirements, like angles or computing units (e.g., bit/byte). The new `Magnitude` class is expected to be defined in such a way that all the operations and unit conversions might be easily performed. The idea is allowing programmers to interact with values+units as intuitively as they currently do with just values. For example: having 5 m/s and wanting to convert it to in/s or to add it to 3 ft/h. Rough sketch of what I have in mind: ``` C# public class Magnitude { public static Magnitude operator +(Magnitude first, Magnitude second) { //It is necessary to confirm whether ""type"" & ""measurement"" are compatible and eventually perform all the required conversions. return new Magnitude((decimal)first.value + (decimal)second.value, first.measurement.unit.ToString()); } //Further basic operator overloads. //Other methods performing basic operations among Magnitude instances. public readonly MagnitudeType type; //The type of the instance has to remain unaltered. public object value { get; set; } //The getter will be defined on account of the ""measurement"" properties. public Measurement measurement { get; set; } public Magnitude(decimal value, string unit) { this.value = value; //The ""unit"" value will be adequately parsed and analysed. //The version below is a simplistic version to show the idea. if (unit == ""m"") { this.type = MagnitudeType.Length; this.measurement = new Measurement(UnitSystem.InternationalSystem, LengthInternational.Meter); } else if (unit == ""ft"") { this.type = MagnitudeType.Length; this.measurement = new Measurement(UnitSystem.ImperialSystem, LengthImperial.Foot); } } //Other overloads accepting different arguments. } public class Measurement { public UnitSystem system { get; set; } public object unit { get; set; } public Measurement(UnitSystem system, object unit) { this.system = system; this.unit = unit; } } //Very simplified versions showing how the enums are expected to look like. public enum MagnitudeType { Length, Weight } public enum UnitSystem { InternationalSystem, ImperialSystem }; public enum LengthInternational { Millimeter, Centimeter, Meter }; public enum LengthImperial { Inch, Foot }; ``` Simple example showing how the aforementioned code is expected to be used: ``` C# Magnitude var1 = new Magnitude(1.234m, ""m""); Magnitude var2 = new Magnitude(5.678m, ""ft""); Magnitude var3 = var1 + var2; ``` I can only think of one drawback for the proposed approach: relying on enums in a situation like this (i.e., with many alternatives and classifications) implies hardcoding a relevant amount of different scenarios. In any case, I think that it would be worthy anyway. CLARIFICATION (from my previous contributions, I understand that this issue should be evident, but just in case...): I am expecting to take care of the proposed implementation completely by my own and also to deliver a comprehensive-enough first version. The initial lack of detail is exclusively motivated by the fact that I prefer to not spend too much time on this before confirming that the .NET community/team likes it. " 6832 area-System.Net Sockets on Unix don't maintain ordering of async operations "If the user initiates multiple concurrent async operations, the expectation (and guarantee, on Windows) is that these will operate on the underlying data stream in the order in which they were submitted. For example, if two asynchronous reads are started, the first read must be satisfied from the first bytes received from the remote peer, and the second read must receive the next bytes, etc. Without this guarantee, it is impossible to reconstruct a data stream received via concurrent read operations. The same ordering requirements apply to writes, for the same reasons. In the current Unix implementation of Sockets, we maintain ordering of operations enqueued to the `SocketAsyncContext`, but we do not actually enqueue operations there before first trying to complete the operation. This allows later operations to ""jump ahead"" of prior operations, in cases where the later operation is started just as data becomes available, but before the `SocketAsyncContext` event loop has had a chance to consume the data. It is important to have this initial attempt to complete the operation before waiting for the asynchronous event, because typically data _is_ available when the operation is initiated, and we don't want to pay the cost of multiple allocations, context switches, etc., for an operation that can complete synchronously. However, if prior operations are already enqueued, waiting for their turn, subsequent operations need to forego the initial attempt to complete synchronously, and wait in line behind the prior operations. See #6806 for an example of a test that fails due to this problem. " 6833 area-System.Net Implement NamedPipe*Stream on Unix domain sockets Today, NamedPipeServer/ClientStream on Unix are implemented on top of FIFOs, aka named pipes. There are some unfortunate limitations to this that are causing problems for typical usage of NamedPipeServer/ClientStream: - FIFOs can be constructed as both read and write (i.e. InOut), but a writer can then immediately read what was written. In other words, whereas one might expect there two be two data channels, one in each direction, there's only one that everyone can read and write from. - FIFOs can be connected to by any number of readers and writers, which has the effect of meaning a reader doesn't unblock when a writer disconnects, because there may be another writer in the future. To address these significant limitations, this commit moves NamedPipeServer/ClientStream to be built instead on top of Unix domain sockets. Unix domain sockets are an IPC mechanism for local communication using the sockets model, and we have support for it via System.Net.Sockets, thanks to #5051. Both of the aforementioned problems are addressed by this change. A few other positive outcomes: - The participants on each side of the connection can get the credentials of the other side, so GetImpersonatedUserName is now implemented. - Our Socket implementation has a good async implementation, so we can use it for all of the async operations exposed rather than queueing a work item that then blocks doing the synchronous operation. There are a few downsides, but they're worth the tradeoff: - FIFOs have the same general blocking behavior as anonymous pipes and as named pipes on Windows: a call to Write doesn't complete until an associated Read comes along. That's not the case with Unix domain sockets, where a Write typically just deposits the data into a buffer. Writes on a socket only block when the buffer is full. - Unix domain sockets are considered to be a bit slower than FIFOs. - Changing the buffer size of a FIFO impacts the whole FIFO, whereas changing the buffer size for a socket impacts just that end of the socket. - There's also a small hack that uses reflection to work around #6807, the lack of an exposed handle property on Socket. Hopefully that'll be fixed soon and then we can remove the hack. There continue to be several features that we don't support on Unix, e.g. message transmission, max number of servers, etc. (One oddity here is that this makes the Unix implementation of System.IO.Pipes.dll have a dependency on System.Net.Sockets.dll, but I spoke with @weshaggard and, other than it being odd, we couldn't come up with any strong reason not to. In the layering, Sockets is already considered lower-level.) cc: @ericeil, @ianhays, @bartonjs, @jaredpar, @AArnott, @cipop, @ericstj, @dsplaisted, @IlyaBiryukov, @bpschoch Fixes https://github.com/dotnet/corefx/issues/1849 6835 area-System.Net Don't get available bytes for the socket unless we actually need the result While reading through the code I noticed that we're making unnecessary `ioctl` calls in Receive calls, to get the count of available bytes. This turns out to only be used if the caller supplied a list of buffers, which is not the typical case. This change moves the `ioctl` call so that it happens only if needed, which should help with throughput in most scenarios. @stephentoub 6838 area-System.Net Ensure ordering of async Socket send/receive operations If the send/receive queue is not empty, don't attempt to synchronously send/receive. Instead, wait our turn behind prior pending operations. This has the unfortunate consequence of making `_queueLock` cover more code. This is solvable, but is a much larger change, which will have to wait for later. It's worth noting that this lock will only experience contention if there are actually concurrent operations, in which case we need _something_ to synchronize/serialize those operations in any case. For mainstream scenarios, I would not expect any noticeable perf impact due to this change.

In usual .NET CLR the `System.Type` and `System.Reflection.TypeInfo` declare the `StructLayoutAttribute` member as the StructLayout cannot be retrieved by calls to `GetCustomAttribute()` or through the `CustomAttributes` property. The consequence of this is that it is impossible to use reflection to get the packing size, or the constant size of a StructLayout marked type.

It's copied from #6846 as it builds on some changes made there.) The second commit adds tests for Socket.Select, which didn't have any other than some tests for argument validation. The third commit changes Unix's SocketPal.Select to be implemented with poll instead of with select. select suffers from the limitation that it only works with file descriptors less than FD_SETSIZE; if the system assigns a file descriptor >= FD_SETSIZE, Socket.Select will fail. This commit changes the implementation to use poll instead of select. (I considered keeping the current Select implementation and falling back to the new one only if a file descriptor >= FD_SETSIZE was found, but after coding it and trying both, it didn't seem worth keeping all of the select code around.)

This allows for reading the per-user registry settings to determine how to find a proxy for a given url. This includes using WPAD protocol to find and execute a Javascript PAC file. The WINHTTP_ACCESS_TYPE_AUTOMATIC_PROXY only works on Windows 8.1 and above. For Windows 7 and Windows 8, we have to manually do the work and the WinInetProxyHelper class provides for that by calling various WinHTTP APIs. This fix is about having the AUTOMATIC_PROXY behaviors work the same whether done automatically by WinHTTP or manually using the WinInetProxyHelper class. In general, errors processing the auto discovery logic should be ignored and the proxy settings should fallback to manual settings if present in the registry. This is difficult to test in an Xunit test since registry settings need to be changed as well as recycling the ""WinHTTP Web Proxy Autodiscover Discovery Service"" since it caches PAC file processing.

This PR is broken up into 3 commits: 1. Adds tests for `ServiceNameCollection`. 100% line and branch coverage, other than the `NormalizeServiceName` method. The tests pass on both the full framework and before/after these changes on .NET Core ~~(other than one behavior difference in `CopyTo` noted below)~~. 2. Removes the dependency on `System.Collections.NonGeneric` and `System.Collections.Specialized`. - `SpnDictionary`: Removed. It's the only thing that depends on the Specialized collections and isn't currently being used anywhere in CoreFX. In the full framework, it's only used in [a few places](http://referencesource.microsoft.com/#System/net/System/Net/_SpnDictionary.cs,3c13c3eec03ce802,references) related to `HttpWebRequest`'s implementation that I don't think is relevant in CoreFX. I also verified it isn't currently used in dev/negotiatestream branch. - `ServiceNameCollection`: No longer inherits from `ReadOnlyCollectionBase` and uses `List` instead of `ArrayList`. - `SslSessionsCache`: Uses of `Hashtable` replaced with `ConcurrentDictionary`. - `SecureChannel`: Uses of `ArrayList` replaced with `List`. 3. `ServiceNameCollection`: Minor perf optimizations and cleanup, while making changes here. ~~Behavior change: In the full framework, `ServiceNameCollection.CopyTo(Array, int)` throws `InvalidCastException` when the destination array is not of a compatible type, but now it throws `ArgumentException` because we now use `List`'s implementation of the non-generic `CopyTo`. Do we need to match the full framework and throw `InvalidCastException` here? (This could have implications for other collections in .NET Core that are now backed by `List` instead of `ArrayList`).~~ **Update**: I added a commit that makes the behavior of `CopyTo` match the full framework. Note: `SslSessionsCache` could use some test coverage around shrinking the cache, but I didn't have a chance to work on it. Not sure if I will anytime soon.

What most developers end up doing is copying the string into a temporary `char[]` or `StringBuilder`, calling the mutable counterparts of the methods in question, and then calling `ToString` on the result. This is wasteful, since two allocations are required: one to copy the data into the mutable buffer, and one to construct a new immutable string. Each of these operations takes O(n) time. `ImmutableArray` solves this problem by having a `MoveToImmutable` method in its 'builder' class, which simply [transfers the array reference](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableArray%601+Builder.cs#L198-L201) to a new `ImmutableArray` and sets its own to an empty one. This takes O(1) constant time and does not require copying any data. ## Proposal I propose adding a `StringBuffer` class that represents a fixed-length, mutable string. Its closest counterpart would be a `char[]`, except that it would use a string as its backing store and thus could be 'moved' directly to a string. Here is a rough sketch of how it would look like: ``` csharp public class StringBuffer { private string value; public StringBuffer(int capacity) { this.value = string.FastAllocateString(capacity); } public StringBuffer(char[] value) { this.value = new string(value); } public StringBuffer(string value) { this.value = string.Copy(value); } public int Length => value.Length; public unsafe void Replace(char from, char to) { if (Length == 0) return; // Modify the string in-place fixed (char* pch = value) { for (int i = 0; i < value.Length; i++) { if (pch[i] == from) pch[i] = to; } } } // Other methods, like CopyTo or ToCharArray // No length-changing methods like Append, // since this is supposed to be a fixed-size buffer public string MoveToString() { // Just do a pointer swap and empty out our reference // No copying needed, so this takes constant time var result = this.value; this.value = string.Empty; return result; } } ``` ## Usage Existing code that looks like this: ``` csharp // Replace non-ASCII chars with question marks char[] buffer = input.ToCharArray(); for (int i = 0; i < buffer.Length; i++) { if (buffer[i] >= 128) buffer[i] = '?'; } var output = new string(buffer); ``` could be converted to look like this: ``` csharp var buffer = new StringBuffer(input); for (int i = 0; i < buffer.Length; i++) { if (buffer[i] >= 128) buffer[i] = '?'; } var output = buffer.MoveToString(); ``` ## Why not add MoveToString on top of StringBuilder? - At the moment, `StringBuilder` is implemented internally on top of a `char` array. If we wanted to add a `MoveToString` method, we would have to refactor it to use a string as its backing store instead. - The move would only be valid if the builder's capacity was equal to its count (see [here](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableArray%601+Builder.cs#L193-L196) for how `ImmutableArray` handles this); if not, the data would need to be copied to a new string anyway, since there would be trailing nulls left off the end of the string. What are your thoughts on this? 6897 area-System.Net [ToFDisable] Port tests for: System.Net* "As part of moving out of ToF and into the open, I've been going through the ""Tree of the future"" tests and calculating which of those tests provide coverage that we're missing in the open tests.

This has some unfortunate implications: 1) We maintain ordering only for the processing of these events. The actual I/O is still unordered, without some extra mechanism. #6838 is a stop-gap fix for this, using the queue lock to maintain ordering of the I/O, but this means that we may block some threads unnecessarily, waiting for other pending I/O to complete. 2) In the current implementation, once we receive the notification, we end up doing the actual I/O operation on the event handler thread itself. This effectively serializes all of the kernel calls involved in the I/O (which includes all of the actual buffer-copies to and from the socket stream data). This impacts scalability significantly, relative to the Windows implementation _and_ Mono on Linux/OSX. 3) Doing the queueing at this level leads to synchronization complexity, which has lead to numerous reliability issues over the last couple of months.

This becomes a much bigger deal when trying to compile these tests for .NET Native, as .NET Native considers these DLLs to be part of the platform and doesn't include them as part of the test ""application"" to be compiled as native. Fixing this will entail either signing with a different key (perhaps just using the OpenKey ) or no key, and removing these attributes. " 6946 area-System.Net Uri percent-encoding inconsistency between .NET Framework and UWP "I am not sure this is the best place to notify Microsoft about the following problem but here we go : I have noticed an inconsistency of HttpClient.SendAsync between ""Console"" and W10 Universal App. The inconsistency can be detected via Fiddler when executing a query with special characters.

On the other side the W10 query parameter finishes by **%82%21**. Here the question mark has kept its HTML escaping. You can also notice that W10 is adding a cookie. Is it a bug of the .NET Framework/HttpClient library? I can assure that the query entered is the SAME in the `HttpClient.SendAsync` as both application uses the same binaries to create and execute the query (and I verified). Here is my code for reference: ``` c# public class HttpClientWebHelper : IHttpClientWebHelper { public async Task GetHttpResponse(ITwitterQuery twitterQuery, HttpContent httpContent = null, ITwitterClientHandler handler = null) { using (var client = GetHttpClient(twitterQuery, handler)) { client.Timeout = twitterQuery.Timeout; var httpMethod = new HttpMethod(twitterQuery.HttpMethod.ToString()); if (httpContent == null) { return await client.SendAsync(new HttpRequestMessage(httpMethod, twitterQuery.QueryURL)).ConfigureAwait(false); } else { if (httpMethod != HttpMethod.Post) { throw new ArgumentException(""Cannot send HttpContent in a WebRequest that is not POST.""); } return await client.PostAsync(twitterQuery.QueryURL, httpContent).ConfigureAwait(false); } } } public HttpClient GetHttpClient(ITwitterQuery twitterQuery, ITwitterClientHandler twitterHandler = null) { var handler = (twitterHandler as TwitterClientHandler) ?? new TwitterClientHandler(); handler.TwitterQuery = twitterQuery; var client = new HttpClient(handler) { Timeout = twitterQuery.Timeout, }; return client; } } ``` This post is a ""duplicate"" of this [StackOverflow question](http://stackoverflow.com/questions/36025004/httpclient-does-not-send-same-request-in-w10-uap). " 6947 area-System.Net WebUtility.UrlEncodeToBytes erroneously returns the full array if no encoding is needed This code prints `1 2 3`, when it should print `2 3`: ``` csharp byte[] input = { 49, 50, 51 }; byte[] output = WebUtility.UrlEncodeToBytes(input, offset: 1, count: 2); foreach (var item in output) Console.WriteLine((char)item); ``` The problem seems to be coming from [this](https://github.com/dotnet/corefx/blob/master/src/System.Runtime.Extensions/src/System/Net/WebUtility.cs#L319) line in the internal `UrlEncode` implementation, which returns the whole byte array disregarding the offset and the count.

This, in windows server which interprets the flags as required, causes the windows server to expect all further communication to be encrypted, which is not the case and hence server side processing fails. To override this behavior, starting MIT Kerberos 1.14 and heimdal implementation, we need to call gss_set_cred_option with GSS_KRB5_CRED_NO_CI_FLAGS_X.

I've been heavily using this system for 14 years now, and it works really well, but most people don't even know it exists, or how to use it. I have created several provider systems, with abstracted interfaces, creating a plug-n-play system for consumers. I've mostly used it for persistence where one consumer may use SQL Server, another may use Oracle, and another may use web services, etc., but it can be used for anything. It also works great for versioning support, where you may be required to support clients that require new data using an old data format. If the new configuration system doesn't support something like this, is there a way to do this in .NET Core? 6999 area-System.Net Where is httplistener? Is it renamed?

When the docker host is Linux, this error does not occur, which leads me to believe it is something wrong with [System.IO.UnixFileSystem.MoveFile](https://github.com/dotnet/corefx/blob/master/src/System.IO.FileSystem/src/System/IO/UnixFileSystem.cs). It is being called from the latest `dotnet` 1.0.0-dev-001806 executable [from here I believe](https://github.com/dotnet/cli/blob/rel/1.0.0/src/dotnet/commands/dotnet-compile-fsc/Program.cs). cc @enricosada Steps to reproduce on Mac OS X: ``` git clone https://github.com/ctaggart/visualfsharp-docker.git cd visualfsharp-docker docker run --rm -ti -v $PWD/template:/root/template ctaggart/visualfsharp:1.0.0-alpha-160318 cd template ./build.sh ``` It will fail with: ``` Unhandled Exception: System.UnauthorizedAccessException: Access to the path is denied. at System.IO.UnixFileSystem.MoveFile(String sourceFullPath, String destFullPath) at Microsoft.DotNet.Tools.Compiler.Fsc.CompileFscCommand.Run(Stringrgs) at Microsoft.DotNet.Cli.Program.ProcessArgs(Stringrgs) at Microsoft.DotNet.Cli.Program.Main(Stringrgs) /usr/share/dotnet/bin/dotnet compile-fsc @/root/template/obj/Debug/dnxcore50/dotnet-compile.rsp returned Exit Code 134 Compilation failed. ``` The compilation actually succeeds and then `dotnet` tries to move the files because `fsc` didn't used to support compiling executables with a `dll` extension like `dotnet` wants.

They provide neither authenticated encryption nor the current best-practice algorithms. According to ""Cryptography in the Web: The Case of Cryptographic Design Flaws in ASP.NET"", > Unauthenticated encryption should be considered harmful. > This is not just a theoretical problem; rather, unauthenti- > cated encryption has repeatedly led to devastating attacks > against real systems. Any cryptographic API should use > authenticated encryption whenever its users want to encrypt > data. The development and popularization of high-level > cryptographic toolkits that include authenticated encryption > such as Keyczar [25], Cryptlib [26], and NaCl [27] is > the first step to providing secure cryptographic software > libraries to the general public. The next step might be the > integration of these cryptographic toolkits into mainstream > web development frameworks. To solve this problem, two steps are required: 1. The existing API should be obsoleted. It uses CBC mode, which is unnecessarily slow, and does not provide authenticated encryption. 2. New, high-level APIs should be provided. A good choice would start with bindings to [libsodium](https://download.libsodium.org/doc/), which provides a high-level C API. Alternatively, similar high-level APIs should be provided. Here is my personal list of algorithms by category. It is based on various sources ([libsodium](https://download.libsodium.org/doc/), CAESAR, TLS), but I am not a cryptographer, so it needs review before it is actually used as the basis for implementation. - Authenticated encryption with associated data: - ChaCha20-Poly1305 - XChaCha20-Poly1305 or XSalsa20-Poly1305 - AES-GCM but possibly only on platforms that have hardware acceleration – it is vulnerable to side channel attacks otherwise. - The CAESAR winner, once that is decided - Nonce-misuse-resistant authenticated encryption - HS1-SIV - Public key cryptography - Ed25519 signatures - Curve25519 key exchange - Deterministic ECDSA signatures and ECDH key exchange, for backwards compatibility. Must use an implementation that is resistant to side-channel attacks. - Possibly RSA but only for backwards compatibility. Should use best known padding: RSA-PSS and RSA-OAEP - Hashing - Blake2b is preferred: very fast & immune to length extension. All options should be exposed, including key and personalization. - SHA2 (both standalone and HMAC) in 256- and 512- bit versions for backwards compatibility - Password hashing and password-based key derivation: - Argon2 - Non-password-based key derivation - Blake2b " 7129 area-System.Security API for manipulating certificates Will you plan to add the ability to create self-signed certificates, create a certificate signing requests - CSR, sign that CSR, and so on? 7131 area-System.Net Merge with master 7134 area-System.Net Fix UrlEncodeToBytes returning entire rather than partial array Port fix from .NET Framework.

Some Frameworks (e.g. Json.NET) however require the xmlns attribute to exist in the memory model, which leads to strange results. My suggestion is: - Either always add the xmlns attribute when using the syntax I wrote above automatically. - Or never add the xmnls attribute (disallow adding it in the api) - also not during parsing xml, but make it implicit (accessible via Name.Namespace) So basically keep the Name.NamespaceName and the xmnls attribute in sync.

The problem only occurred on Windows 7 because the proxy initialization code in WinHttpHandler is different for that platform.

The ""init once"" logic was faulty because it was setting the `_sessionHandle` field too early before everything was init'd. In addition, this exposed another bug where the session handle options were repeatedly set for each request even though they should only have been set once. Fixed up the EnsureSessionHandleExists method to do the proper initialization. Also added more tracing.

"FileInfo.Length on a symbolic link in Windows returns 0, not the length of the file referred to by the link. For a symbolic link, Windows’ FindFirstFile returns 0 bytes as the length.

Jeremy Kuhne points out it's best if we open then handle without requesting read or write permission (ie calling CreateFile with the right parameters).

This not sufficient, and is fact ignored by the framework which instead checks to see if AuthenticationType is set. - IIdentity has only three properties, one of which being IsAuthenticated. Even if you are unfamiliar with old approaches of implementing CustomIdentities, the first thing you would do is look at the default ClaimsIdentity and see what interfaces does it implement. IIdentity is the only one. So naturally you would conclude that your custom identity must simply implement this interface. This is not sufficient. - No interface describes the additional requirements needed to be a successfully functioning custom identity. - You must magically know that you must inherit from ClaimsIdentity - When using only a ClaimsIdentity directly, you can successfully authenticate the user. The framework automatically creates the necessary token so long as AuthenticationType is set. However, a custom identity implementing ClaimsIdentity for some reason does not get the same benefit from the framework. Having IsAuthenticated==true and AuthenticationType set means nothing to the framework if you are instead inheriting from ClaimsIdentity. As soon as you derive from ClaimsIdentity, you then have to set the token yourself. - Returning a principal from the ClaimsAuthenticationManager leads one to the think the framework will then pick that up and use that as the principal if IsAuthenticated==true. In fact, as demonstrate in the below, many other steps are needed to get the principal and identity to ""stick"". Why doesn't this method just have a void return type if it isn't going to respect the return? - If an Identity with IsAuthenticated==true and no AuthenticationType==null means the user is interpreted as not authenticated, then this should be an exception. Clearly if an identity is returning true for IsAuthenticated, the indication is the user should be authenticated. If you are going to have an obscure nuance that AuthenticationType must also be set, then an exception should be thrown so developers are not dealing with what is essentially a silent error as result of them failing to set the AuthenticationType. Really this type of lock step should be avoided when trying to represent a single concept in multiple properties. You're trying to represent the fact that a user is successfully authenticated, and if some other required information is missing to satisfy that discrete value, then throw an exception. - If IsAuthenticated==true is ignored for types which implement IIDentity, but are not a ClaimsIdentity then this should again be an exception. If you're going to let my IIdentity interface return an AuthenticationType and IsAuthenticated==true, and then completely ignore the information I've exposed through the one and only interface that is used by the Identity class hierarchy, then throw an exception that makes it clear that identities not inheriting ClaimsIdentity are not supported. -Other aspects of the framework require specific claims be present. There's no compile/design time safety or other measures to verify my implementation is correct until I stumble upon them later. AntiForgeryToken is an example that you will not reallize requires a specific claim until you stumble onto a page with it on there. I do not know what other things I will stumble upon that will bite me because it is a dirty stringly type dependency on a specifically named claim. Ideally these requirements should be represented as properties on an interface. If you so choose not to support the feature, you can opt not to implement the interface and suffer a lack of support for the feature. This allows you to compose interfaces into an identity that supports your needs. - Will I run into problems because my CustomIdentity does not implement all the many and varied signatures of the ClaimsIdentity construct? One would usually think no, but the fact that we're now doing things like requiring a specific concrete class, stringly typed claim values, and not communicating API requirements through interfaces means that I have to wonder if specific constructor signatures may be required by certain parts of the framework, and I will painfully discover later through a bug which is unlikely to throw an exception. - Will I run into problems that basically invalidate my entire approach down the road? - Now that I'm setting the token myself, is there potential for problems with stepping on the framework's own code for handling the token? - Do I need to do all the stuff to manage the sliding expiration of the token and all other related stuff? Will the framework still handle this for me? Not really looking for an answer, as much to point out the strangeness that I must take on setting the token when I'm still returning a derived ClaimsIdentity, which calls into question what else I must take on that was automatically handled by the framework. - This is one of those things where the combination of things to get it working doesn't really make any sense. One of my other developers figured out that the token needed to be set, and I was very doubtful of that. What is so different between returning a ClaimsIdentity and a derived custom ClaimsIdentity? That with the obscure nuances of what can break it, and the fact that I may find certain scenarios in the future that do not work with this crazy combination of settings. I am setting my expectation to have users complain of edge case scenarios where they have problems with authentication, and no amount of exception logging will help me identify the problem because clearly there's several scenarios where we are just silently failing to authenticate due to a failure to meet obscure requirements to set a certain property a certain way. So I can look forward to encountering these in the future and hunting through the reference source to try and guess at what obscure requirement I am missing that is causing certain users to have problems. Hopefully this doesn't sound to ranty. Here's the path I took. Actually the final combination of inheriting from a ClaimsIdentity AND setting the token was found by another developer. It actually involved a ~week of each of 3 developer's time before we found the right combination. Between all the identity factories, ApplicatonUser factories, UserStore's, and UserManager's(conceptually similar names that seem to represent the same purpose, but really server different role) we had alot to investigate. ``` public class KentorAuthenticationManager : ClaimsAuthenticationManager { public override ClaimsPrincipal Authenticate(string resourceName, ClaimsPrincipal incomingPrincipal) { // create our custom identity var customIdentity = new CustomIdentity(); customIdentity.IsAuthenticated = true; customIdentity.AuthenticationType = ""testtype""; customIdentity.Name = ""John Doe""; var newPrincipal = new ClaimsPrincipal(customIdentity); base.Authenticate("""", newPrincipal); HttpContext.Current.User = newPrincipal; System.Threading.Thread.CurrentPrincipal = newPrincipal; return newPrincipal; } } [Serializable] public class CustomIdentity : //System.Security.Claims.ClaimsIdentity, IIdentity, IIdentityContext { public CustomIdentity()//:base(""UnifiedEngagement"") { } public int UserId { get; set; } public string Name { get; set; } public string AuthenticationType { get; set; } public bool IsAuthenticated { get; set; } // other custom properties... } ``` The problem is the custom identity gets converted to a claims identity: [![enter image description here](http://i.stack.imgur.com/IFTzM.png)](http://i.stack.imgur.com/IFTzM.png) ## Generic Principal w/CustomIdentity If we use a GenericPrincipal, then within the CustomAuthenticationManager, the newPrincipal.Identity is my custom type: `var newPrincipal = new GenericPrincipal(customIdentity);` [![enter image description here](http://i.stack.imgur.com/h1VRa.png)](http://i.stack.imgur.com/h1VRa.png) [![enter image description here](http://i.stack.imgur.com/u3gCL.png)](http://i.stack.imgur.com/u3gCL.png) Looking good, until the roundtrip completes and accessing the current principal from anywhere else, it then shows a GenericIdentity with `IsAuthenticated==false`, which loses all the extra properties that were in my CustomIdentity: [![enter image description here](http://i.stack.imgur.com/igbYB.png)](http://i.stack.imgur.com/igbYB.png) Essentially it ignored the IsAuthenticated==true I set(I also set AuthenticationType since WIF depends on that to determine authentication). If I use a ClaimsIdentity, all I have to do is make sure it is instantiated with a AuthenticationType and it authenticates properly. ## GenericPrincipal w/CustomIdentity and setting SessionSecurityToken I shouldn't need to do this, because based on setting IsAuthenticated and the AuthenticationType, it should authenticate automatically and generate the token. So to force it to authenticate successfully, I explicitly set the session token. But my CustomIdentity is gone and is instead a ClaimsIdentity after the roundtrip, and so loses my custom properties(It does create claims representing the IIdentity properties for name, nameid, etc. but all other custom properties are lost): ``` var sessionSecurityToken = new SessionSecurityToken(newPrincipal, TimeSpan.FromHours(8)); FederatedAuthentication.SessionAuthenticationModule.WriteSessionTokenToCookie(sessionSecurityToken); ``` After roundtrip CustomIdentity is now a ClaimsIdentity: [![enter image description here](http://i.stack.imgur.com/GImlL.png)](http://i.stack.imgur.com/GImlL.png) ## Inheriting ClaimsIdentity If my CustomIdentity inherits from ClaimsIdentity: ``` [Serializable] public class CustomIdentity : System.Security.Claims.ClaimsIdentity, IIdentityContext { public CustomIdentity(IIdentity claimsIdentity) : base(claimsIdentity, null, ""TestAuthType"", null,null) { } //... ``` But I do **not** explicitly set SessionSecurityToken(no call to WriteSessionTokenToCookie), then it fails to authenticate and leaves me with a GenericIdentity with IsAuthenticated==false. ## Inheriting ClaimsIdentity w/setting SessionSecurityToken If I use the above identity that inherits from ClaimsIdentity **and** set SessionSecurityToken, then everything works fine. It was a long road to get here. 2 senior and 1 midlevel developer spent roughly a week each trying different variations.

Note I have enough custom properties that I am not looking to stuff them in as claims. The recommendation I've seen on more than one occasion is that putting too much into claims is a poor design and can cause poor performance because they end up in the token. Additionally, some data is much easier to represent in a C# object model than within a flat list of claims. It is data specific to the user, minimal enough that the memory footprint in session is acceptable, and large enough that I wouldn't want it encrypted/decrypted and pushed across the wire: https://msdn.microsoft.com/en-us/library/azure/hh531494.aspx " 7196 area-System.Net Merge System.Net.Sockets.Legacy tests into System.Net.Sockets This reduces duplication in the Sockets tests, and reduces the innermost development loop for Sockets changes to a single test assembly.

The Abort() method immediately attempts to take a lock on `_operation.Lock`. Inside the using block of ConnectAsync, there are two inner blocks which take a lock on `_operation.Lock`. While in the second lock, if the CancellationToken is cancelled, a deadlock occurs. What happens is the callback is fired, which calls Abort() which then blocks waiting to obtain a lock on `_operation.Lock`. This lock can't be taken because ConnectAsync is holding the lock. At the end of the second lock block in ConnectAsync, a call to ctr.Dispose() is made. When calling Dispose() on a CancellationTokenRegistration, if the cancellation callback is currently in progress, it blocks waiting for the callback to complete. The callback won't complete because it's waiting for the lock to be released by ConnectAsync. ConnectAsync won't release the lock until the Dispose() call completes, which won't complete until the callback is complete.

Original project.json is as follows: ``` { ""dependencies"": { ""Microsoft.NETCore.UniversalWindowsPlatform"": ""5.0.0"" }, ""frameworks"": { ""uap10.0"": {} }, ""runtimes"": { ""win10-arm"": {}, ""win10-arm-aot"": {}, ""win10-x86"": {}, ""win10-x86-aot"": {}, ""win10-x64"": {}, ""win10-x64-aot"": {} } } ``` **Tweak a.** Change ""dependencies"": {""Microsoft.NETCore.UniversalWindowsPlatform"": ""5.0.0""} -> ""5.4.0"" => Try to add System.Net.Sockets again. Fails. **Tweak b.** Add ""dotnet5.4"": {}, into ""frameworks"": { ""uap10.0"": {} }, => Try to add System.Net.Sockets again. Fails. **Tweak c.** Delete ""uap10.0"": {} after adding ""dotnet5.4"": {} into ""frameworks"". => Try to add System.Net.Sockets again. Fails. ### REFERENCE Can't locate TcpClient and TcpListener from Socket.Net.Sockets #5939 *) This page says you have to switch platform to ""dotnet5.4"".

Like so: ``` C# public static string Concat(this IEnumerable values, string separator = """") => string.Join(separator, values); ``` it's considerably more flexible and enjoyable to use especially when chaining together with Linq to objects queries: ``` C# intList.Where(n => n > 50).OrderBy(n => n).Concat("", "") ``` as oppose to: ``` C# string.Join("", "", intList.Where(n => n > 50).OrderBy(n => n)) ``` So if I'm not the only one using this method this way, maybe we can add it to the corefx. **Note:** I named it `Concat` because there already exists a standard query operator called `Join`. The name is as much up for discussion as the feature itself.

We will receive an exception of type ArgumentException ``` C# using System.Collections; using System.Collections.Generic; using System.Linq; namespace TestX { class Program { static void Main(string[] args) { var dictionary = new Dictionary(); dictionary.Add(""Test"", ""Ok""); // new dictionary element var dictionaryAsCollection = dictionary as ICollection; var buffer = new KeyValuePair[1]; dictionaryAsCollection.CopyTo(buffer, 1); // 1 is out of bounds for buffer Console.WriteLine(buffer.First()); } } } ``` For (almost) all the standard collections there are an issue: when CopyTo starting index is equal to destination buffer length, no ArgumentOutOfRangeException is thrown. For me it seems inconsistent: CopyTo(buffer, 1) should throw ArgumentOutOfRangeException in all cases except CopyTo(buffer, 0), because this time it is only valid argument value.

Today, even if there aren't any cookies for the given Uri, this ends up doing a lot of allocation. And if there are cookies for the Uri, the serialization of each cookie results in a handful of strings, char[]s, and string[] allocations. This commit tweaks the implementation to avoid a bunch of these, including taking advantage of StringBuilderCache. (There are still some more that could be cleaned up with further work, but it becomes much more invasive.) For this sample program: ``` C# CookieContainer cc = new CookieContainer(); Uri exists = new Uri(""http://example.com/exists""); Uri notExists = new Uri(""http://example.com/notExists""); cc.Add(exists, new Cookie(""test1"", ""value1"")); cc.Add(exists, new Cookie(""test2"", ""value2"")); for (int i = 0; i < 1000; i++) { cc.GetCookieHeader(exists); } ``` before these changes, I see the following allocations: ![image](https://cloud.githubusercontent.com/assets/2642209/14066895/e68b9854-f424-11e5-910e-a65caff8f4ce.png) and after thes changes: ![image](https://cloud.githubusercontent.com/assets/2642209/14066898/14d278ae-f425-11e5-8f07-82bb29139f59.png) If I then change the GetCookieHeader line to be: ``` C# cc.GetCookieHeader(notExists); ``` before these changes, I see the following allocations: ![image](https://cloud.githubusercontent.com/assets/2642209/14066925/ad052856-f425-11e5-9049-1e38d8432687.png) and after these changes: ![image](https://cloud.githubusercontent.com/assets/2642209/14066930/c066e6c8-f425-11e5-82ce-989b6692d0a8.png) cc: @davidsh, @cipop, @ericeil " 7289 area-System.Net WebHeaderCollection: Specify ArgumentException paramName Split `CheckBadChars` into separate `CheckBadHeaderValueChars` and `CheckBadHeaderNameChars` methods and use `nameof` to include the `paramName` when throwing `ArgumentException`. 7292 area-System.Net Remove unnecessary string allocations in MultipartContent "More low-hanging fruit.

HttpClient has its own stream-to-stream copy implementation, but there are ways we can significantly improve it based on typical usage within HttpClient. This commit does the following: - Previously it would special case when both the source and destination stream were MemoryStreams, but even in that case it would allocate a temporary buffer and do a Read/Write loop to copy between them, and even then it's relatively rare to copy from a MemoryStream to a MemoryStream. Instead, if the source stream is a MemoryStream and we can get its buffer, we can do a single write to the destination (regardless of what kind of stream it is), avoiding the need for multiple read/writes and for the temporary buffer. If we can't get its buffer but its length is known to be less than or equal to the requested buffer size and it's positioned at the beginning, we can simply ToArray the source and still do a single write to the target. - If the destination is the special LimitMemoryStream, used for buffering output, and if that LimitMemoryStream was pre-sized based on the response having a Content-Length, then rather than allocating a temporary buffer and repeatedly copying from the source stream into that buffer and copying from the buffer into the memory stream, we can instead give the destination's buffer directly to be read into by the source, avoiding the temporary buffer and the extra copies. This is a very common case. - If the source does not need to be disposed after the copy, rather than doing our own copy loop, we can instead ask the source to use its CopyToAsync implementation to copy to the destination stream. Worst case this will be exactly what we were previously doing, but best case the source has its own CopyToAsync override that's more efficient. - When constructing a LimitMemoryStream, if the Content-Length isn't known, we were explicitly passing a 0 capacity to the base, which causes it to allocate a new zero-length array; I've added a ctor to avoid that. As a small example, with this short test: ``` C# var uri = new Uri(""http://httpbin.org/get""); var c = new HttpClient(); for (int i = 0; i < 100; i++) c.GetAsync(uri).GetAwaiter().GetResult().Dispose(); ``` before the change it allocated 1,411,714 bytes, and after the change, it allocated 1,003,702, for an ~30% reduction. That drop is almost entirely in avoiding needing byte[]s: I'd appreciate some extra scrutiny on this. cc: @davidsh, @cipop, @ericeil, @kapilash, @bartonjs, @ianhays " 7304 area-System.Numerics Vector while debugging incorrectly reports size of register The `Vector` type on a machine which supports 256 bit registers will return 8, however the debug/non-accelerated version of the register only will act as a 128bit register.

From a readability/maintainability perspective, the code is now more concise and linear, which should hopefully be evident from the diff.

When a request comes in and that worker thread isn't running, a worker is spun up, and that worker will service any number of requests that come in while it's up. Then, when requests quiesce and there's no more processing to be done, the worker goes away. If more work later arrives, a new worker is spun up. This is done to avoid burning a thread per HttpClient when there's no work to be done on that client. It works well for bursts of activity as well as for sustained concurrent usage. However, if the client is used for a sequence of requests, one after the other, there's a good chance that the worker will go away between requests, requiring a new worker to be spun up for each. This has non-trivial costs, both in terms of CPU processing and in terms of managed and native resource allocation/deallocation. This commit enables a worker to briefly pause before exiting, blocking for a short period of time for new work to arrive rather than simply exiting. With a simple serial workload like: ``` C# using System; using System.Diagnostics; using System.Net.Http; using System.Threading.Tasks; public class Program { public static void Main() { MainAsync().GetAwaiter().GetResult(); } private static async Task MainAsync() { var c = new HttpClient(); var url = new Uri(""http://httpbin.org/ip""); while (true) { var sw = Stopwatch.StartNew(); for (int i = 0; i < 100; i++) { await c.GetStringAsync(url); } Console.WriteLine(sw.Elapsed.TotalSeconds); Task.Delay(500).Wait(); } } } ``` Prior to this change, each run of 100 requests would end up spinning up anywhere between 20 and 40 workers, whereas after the change it typically only spins up 1. This has a significant impact on throughput, typically doubling throughput of this test on my machine, e.g. before: ``` 4.1502928 3.8951023 4.7506992 4.0254529 ``` and after: ``` 2.2819518 1.9307756 1.9129248 1.8165896 ``` cc: @ericeil, @kapilash, @davidsh, @cipop " 7323 area-System.Globalization Add a few culture tests to System.Globalization Ports missing ToF tests to Open. resolves #6429 7325 area-System.Security Open System.Security.Principal.WindowsIdentity As a developer I need access to the current logged in active directory user to check if the user has a specific role.

I want to wait until that process exits and if it fails to exit in five seconds I want that process terminated. Here's a piece of pseudocode: ``` if( !process.WaitForExit( 5000 ) ) { process.Kill(); } process.Dispose(); ``` The problem is the process might exit between `WaitForExit()` and `Kill()` and then this code gets a rather generic exception. There's no way to write the code above such that there's no potential for the race condition between the other process exiting and this process making the decision of whether to terminate the other process or not. Same problem on desktop. There're three approaches to how this can be resolved. The first one is that `Kill()` does nothing if the process has exited. This would violate the contract stated in the documentation but it's actually the right thing to do. The purpose of `Kill()` is ""get rid of the process"" and if it so happens the process has exited - okay, nothing to do. I cannot imagine a reasonable case where someone would blindly call `Kill()` and then catch the possible exception and make any decisions on what to do based on whether there was an exception. The second one is that a parameter with a default value is added to `Kill()` - such that it turns into `Kill( bool throwIfExited = true )`. This prevents violating the current contract but honestly it's stupid. The third one is crafting some special exception exactly for this case - such that the caller can reliably detect that the process has exited by programmatically inspecting the exception. This would break the contract and it's also stupid.

In general, it seems that we are restoring some Windows binaries which fails early on, usually before any test runs. It seems that certain tests are not fully specifying their dependencies, which results in old versions of packages being pulled in. For example, System.Globalization.Tests.csproj, if run with the above command, fails when calling `Directory.GetCurrentDirectory()` in the Xunit console runner, because the System.IO.FileSystem.dll that is deployed next to the test is the Windows version. If you explicitly add a new version of this package to the tests dependencies, it is successfully restored and the test project gets further. Then it fails because the version of System.Runtime.InteropServices.RuntimeInformation.dll is the Windows version. If you add THAT to the project.json, then the tests finally pass. Easy repro: ``` cd src/System.Globalization/tests /t:RebuildAndTest /p:OSGroup=OSX ``` Interestingly, this issue does not occur if you ALSO pass `/p:TestWithLocalLibraries=true`. I haven't figured out what is happening in this case, but the correct DLL's seem to be copied in if this flag is set. It also shouldn't be necessary to pass `/p:OSGroup=OSX`, either. If this is omitted, no tests are run, though. We should auto-detect this and run tests anyways. We should have the information to make this possible. It's likely that this is also affecting the other non-Windows builds. @Priya91, @joperezr 7377 area-System.Reflection Consider adding PureAttribute to IntrospectionExtensions.GetTypeInfo Porting some code to .NET Core, I encountered the following code: ``` C# public static Type FindImplementationType(Type type, ObjectLiteral objLit, Func getResolverKind) { Contract.Requires(type.IsInterface); // ... } ``` So I added the call to GetTypeInfo(): ``` C# Contract.Requires(type.GetTypeInfo().IsInterface); ``` However, when code contracts actually runs, I get the following error: > error CC1036: Detected call to method 'System.Reflection.IntrospectionExtensions.GetTypeInfo(System.Type)' without [Pure] in contracts of method 'Util.ConfigurationConverter.FindImplementationType(System.Type,ObjectLiteral,System.Func`1)' Is it possible to add a PureAttribute to the GetTypeInfo() method? That seems like it might be a dependency we don't want to add to the contract, is there another way of specifying that a method is pure for code contracts? Should the attribute at least be added to the .NET Framework version of this method? 7379 area-System.Net Refactor MultipartContent to use async/await "Currently serialization of MultipartContent is split across multiple Task-based methods that each ContinueWith to each other. We can instead just write the code naturally in an async method. In addition to being simpler, it also helps with performance, especially when serializing to a memory stream and the whole operation can actually run synchronously. For example, with this little snippet: ``` C# var c = new HttpClient(); var url = new Uri(""http://httpbin.org/post""); for (int i = 0; i < 100; i++) { var mc = new MultipartContent(""someSubtype"", ""theBoundary""); mc.Add(new ByteArrayContent(Encoding.UTF8.GetBytes(""This is a ByteArrayContent""))); mc.Add(new StringContent(""This is a StringContent"")); await c.PostAsync(url, mc); } ``` the number of allocations drops nicely: ![image](https://cloud.githubusercontent.com/assets/2642209/14164603/e51fe004-f6ce-11e5-893e-9c1d10480102.png) cc: @davidsh, @cipop, @ericeil, @kapilash " 7380 area-Infrastructure Code coverage builds failing due to bin clashes "The last few code coverage builds in CI have failed, with lots of errors like this: ``` 16:19:59 Error : Multiple projects built twice with the same target path d:\j\workspace\code_coverage---7bd9c464\bin\ref\System.Threading\4.0.10.0\System.Threading.dll. 16:19:59 d:\j\workspace\code_coverage---7bd9c464\build.proj --> 16:19:59 Global Properties: 16:19:59 Coverage = true 16:19:59 d:\j\workspace\code_coverage---7bd9c464\src\tests.builds --> 16:19:59 Global Properties: 16:19:59 Coverage = true 16:19:59 DefaultBuildAllTarget = BuildAndTest 16:19:59 BuildAllProjects = true 16:19:59 d:\j\workspace\code_coverage---7bd9c464\src\System.Threading\tests\System.Threading.Tests.csproj --> 16:19:59 Global Properties: 16:19:59 Coverage = true 16:19:59 BuildAllProjects = true 16:19:59 OSGroup = Windows_NT 16:19:59 d:\j\workspace\code_coverage---7bd9c464\src\System.Threading\src\System.Threading.csproj --> 16:19:59 Global Properties: 16:19:59 Coverage = true 16:19:59 BuildAllProjects = true 16:19:59 OSGroup = Windows_NT 16:19:59 d:\j\workspace\code_coverage---7bd9c464\src\System.Threading\ref\System.Threading.csproj 16:19:59 Global Properties: 16:19:59 Coverage = true 16:19:59 BuildAllProjects = true ``` and then a note at the end: ``` 16:19:59 MSBUILD : error MSB4015: The build stopped unexpectedly because the ""ReusableLogger"" logger failed unexpectedly during shutdown. 16:19:59 System.Exception: 66 bin clashes were detected during the build. 16:19:59 at Microsoft.DotNet.Build.Tasks.BinClashLogger.Shutdown() 16:19:59 at Microsoft.Build.Evaluation.ProjectCollection.ReusableLogger.Shutdown() 16:19:59 at Microsoft.Build.BackEnd.Logging.LoggingService.ShutdownLogger(ILogger logger) ``` @ericstj, does this look familiar? http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/code_coverage_windows/204/consoleFull " 7383 area-Infrastructure Unix builds fail when trying to sign a project Calling `./build.sh /p:ConfigurationGroup=Release` throws the following error: ``` CSC : error CS7027: Error signing output with public key from file '/mnt/j/workspace/dotnet_corefx/outerloop_ubuntu14.04_release/Tools/Test.snk' -- Cannot marshal 'return value': Unknown error.

It has to do with the runtime and applying a migration.

To resolve, I need to restore the **dnx451** framework in the project.json and use the **mono** runtime. Then, it works. My database is SQL Server running on Amazon RDS.

This refactors that synchronous processing into its own method, and changes ReadAs methods to use a simple async method that does the await on LoadIntoBufferAsync and then calls these methods. This avoids any task-related allocations if the data is already buffered. It also makes those synchronous methods callable from the GetString/ByteArrayAsync directly, such that these methods can avoid an extra layer of continuations, as they already do their own buffering. I will separately follow-up on converting the rest of HttpContent to use async/await where it makes sense. cc: @davidsh, @cipop, @ericeil, @kapilash 7407 area-System.Runtime Add Byte, Int16, Int32, Int64, SByte, UInt16, UInt32 and UInt64 tests - Take advantage of xunit - Refactor and add tests for Parse and ToString Contributes to #6286 Cherry picked from #5490 Helps test dotnet/coreclr#3995 7408 area-System.IO Add SetCurrentDirectory test for a symlink path resolves #7358 @stephentoub 7409 area-System.Runtime Regression in StringBuilder.AppendLine and Console.Write and Console.WriteLine "This code: ``` csharp static void Main() { var sb = new StringBuilder(); sb.Append(""hello""); sb.AppendLine(); sb.AppendLine(); sb.Append(""world""); sb.AppendLine(); var s = sb.ToString(); Console.WriteLine(s); } ``` In .NET Framework 4.6, it prints this output (with a completely empty line between the two words): ``` hello world ``` But when I write it in a dotnet-cli console app (generated using ""dotnet new"", and targeting `""frameworks"": {""netstandard1.5""}` and dependency `""Microsoft.NETCore.App"": { ""version"": ""1.0.0-rc2-23930""}`, then it omits the blank line: ``` hello world ``` " 7416 area-Serialization DataConstractJsonSerializer should Escape '<', '>', and '& "@cyberphone submitted the following suggestion in #5647 > Having looked around a bit it seems that the JSON world is rather divided and needs to consider supporting two different serializations, one which is ES6-compatible and another which is ES6-compatible but properly escaped to be declared in browser as a JavaScript object.

The following characters are reserved and cannot be used for this property: semicolon, comma.** - MSDN does not make it clear if an exception is thrown or not in the above circumstances. - However, in corefx, the second condition is not checked. If a value is null, it is converted to an empty string. ## Solutions - Fix the documentation according to the current behaviour - Adapt the documentation for Cookie.Value Property and change some current behaviour - Change all the behaviours to that described in the MSDN docs ## Notes - Corefx currently aligns with the behaviour of .NET desktop (no exceptions are thrown there) - I reckon its quite important to ensure that Cookie.Value can never be null, as this is documented in MSDN and therefore can lead to NREs. The solutions to this are throwing an exception or setting Cookie.Value to string.Empty /cc @davidsh 7462 area-System.Net Fix CurlHandler Content-Length handling on redirects CurlHandler was explicitly setting the Content-Length header, which overrides libcurl's default handling of Content-Length. This means that Content-Length was being sent even when it shouldn't have been, such as when redirecting a POST to a GET. This commit changes how we handle Content-Length. Rather than explicitly setting the header ourselves, we let libcurl do it, and we tell it the length of the input via the INFILESIZE and POSTFIELDSIZE options. A few other issues addressed as well in the act of fixing this: - A SafeHandle wasn't being disposed of in the case of a redirect. - 301 wasn't being considered a redirect status code for the purposes of credential handling. - Some code could have been a bit cleaner.

I propose considering changing the build to be a release build for the following reasons: 1. Some debug code will always be uncovered (e.g. numerous `internal void Dump()` methods in System.Net or System.Text.RegularExpressions) 2. Release mode tends to run quicker than debug (I don't have empirical evidence to prove this, and this is definitely a smaller reason than 1.) 3. Tests (typically) test code that the API consumer calls publically to a .dll file built in release mode. If any behaviour is considerably different in release mode then it may not be covered in debug CC runs. This could cause problems. 4.

This breaks the SignalR client in Universal Windows Platform apps. Here is an example of code that will hang indefinitely if HttpResponseMessage.Dispose() is called before the response body is completed. ``` c# using (var client = new HttpClient()) { var request = new HttpRequestMessage(HttpMethod.Get, ""http://localhost:5000/""); HttpResponseMessage response = null; var ignore = Task.Delay(5000).ContinueWith(_ => { mLogger.WriteLine(""Canceling request""); response.Dispose(); }); mLogger.WriteLine(""Making request""); response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead, CancellationToken.None); mLogger.WriteLine(""Got headers""); var buffer = new byte[1024]; int count = -1; var responseStream = await response.Content.ReadAsStreamAsync(); while (count != 0) { mLogger.WriteLine(""ReadAsync""); count = await responseStream.ReadAsync(buffer, 0, 1024); mLogger.WriteLine(""Finished ReadAsync""); } mLogger.WriteLine(""Request complete""); } ``` **Expected behavior (which happens with the dnxcore50 assembly):** When HttpResponseMessage.Dispose() is called, the ongoing call to responseStream.ReadAsync throws a TaskedCanceledException. **Actual behavior (which happens only with dotnetcore50 assembly):** stream.ReadAsync never completes after HttpResponseMessage.Dispose() is called. To make matters even worse, when/if the response body actually does complete, responseStream.ReadAsync _still_ never finishes. **Note:** If the CancellationToken that is passed to Send is canceled before client.SendAsync completes, SendAsync will throw a TaskedCanceledException with both the dnxcore50 and netcore50 versions of System.Net.Http.

Stack trace/message of the exception: ``` System.ArgumentException: The parameter is incorrect. hostName at Windows.Networking.Connectivity.NetworkInformation.GetHostNames() at System.Net.NetworkInformation.HostInformation.GetFixedInfo() at System.Net.NetworkInformation.HostInformation.get_FixedInfo() at System.Net.NetworkInformation.HostInformation.get_DomainName() at System.Net.CookieContainer..ctor() at System.Net.Http.HttpClientHandler..ctor() ``` The last function in the call stack: [`NetworkInformation.GetHostNames`](https://msdn.microsoft.com/library/windows/apps/windows.networking.connectivity.networkinformation.gethostnames), which doesn't take any parameters. Therefore, I don't which parameter `hostName` could be wrong that I am passing causing the exception. ### Steps to fix/reproduce I figured out how to work around the problem: - Goto `Control Panel\All Control Panel Items\System` -> `Advanced System Settings` -> `Computer Name` -> `Change` -> `More` - Clear what's in the text box of ""Primary DNS suffix of this computer"" (it was `42` before, since this is my local dns suffix, so the FQDN of my host is `hostname.42`). - This is reproducible on my machine. Didn't test this on other machines. - It works using a DNS suffix which is not a number (tested with `foo`). If this behaviour is intended, the possibility of an exception when calling `NetworkInformation.GetHostNames` should be documented. Windows Build: Version 1511 (10586.164) Edit: What I think is that NetworkInformation.GetHostNames() calls `GetAllHostNames()` from `Windows.Networking.HostName.dll` (listed as import of the dll of NetworkInformation). The `HostName` constructor is then used to create the instances of `HostName`. I think the call to the function `HostNameImpl::CanonicalizeHostName` fails, since it raises an exception when it fails. Maybe it's [`DnsValidateName`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms682032%28v=vs.85%29.aspx) that classifies the host name `host.42` as invalid (which seems correct to me).

This was done for simplicity of resource management, but it also leads to significant overheads due to everything that libcurl caches associated with the multi handle, e.g. when the multi handle goes away, so does it connection cache, its DNS cache, etc. This commit addresses that by extending the lifetime of the multi handle to match that of the CurlHandler. We still lazily create the handle when the first worker is spun up, but then we keep it alive until the CurlHandler is disposed. As before, we ensure that as long as a worker is running, the multi handle will be kept alive, even if the handler is disposed. 2. **Extend DNS cache timeout in CurlHandler.** Now that we're allowing the multi handle to live for as long as the CurlHandler, the DNS cache timeout starts to matter much more. libcurl will cache the results of DNS lookups, and by default will timeout entries after 1 minute. Our Windows implementation defaults to 10 minutes, so I'm extending our Unix implementation to match that. 3. **Only call curl_multi_wait if there are active operations.** The CurlHandler work is sometimes hitting pauses unnecessarily, where it finishes processing the last active request and then calls curl_multi_wait to wait for more work to do. This is purely wasteful and can be skipped when we know there aren't any more active operations. 4. **Improve reliability of CurlHandler MultiAgent worker.** If something unexpectedly goes wrong in our worker loop, and in particular when queuing a replacement worker, we may end up leaving a request sitting in the request queue with no one to process it. This commit ensures that if something does go horribly wrong, the agent is left in a state where subsequent incoming requests can still kick off another worker, and in the meantime any pending requests in the queue are failed, so that code blocking on them doesn't simply hang.

I propose adding APIs to parse a string from an index, with an additional overload specifying the length. ## Rationale In order to parse part of a string, we need to perform a `string.Substring(...)` method on the string. This results in allocations, affecting performance. ## Proposed APIs - with slices ``` csharp public int Parse(ReadOnlySlice s) public int Parse(ReadOnlySlice s, IFormatProvider format); public bool TryParse(ReadOnlySlice s, out int i); public bool TryParse(ReadOnlySlice s, IFormatProvider format, out int i); ``` ## Proposed APIs - without slices ``` csharp public class Int32 { // Proposed new APIs public int Parse(string s, int index); // Either public int Parse(string s, int index, int count); // or Public int Parse(string s, int index, int length); // or public int Parse(string s, int startIndex, int endIndex); // Existing parsing APIs public int Parse(string); ... } ``` ## Discussion - These overloads should be intelligent and not allocate any substrings - I assume TryParse overloads would also have to be added - Would we need to add overloads taking an IFormatProvider too - How common is this use case? - Is this worth adding 4 public methods to each integer type? - Should we bother with the `Parse(string, int)` overload? I think most people calling his API would know the required length. ## Example I added some custom parsing code in a PR in coreclr (dotnet/coreclr#3992). This is basically the code that these proposed methods would use. Parsing performance of ints in Version increased by up to 4x due to reduced substring allocations. Another example is Guid (dotnet/coreclr#3965) where performance of parsing Guid strings increased by up to 3x with the allocation count reducing to 0. ## Alternatives - Add a `Parse(char* s, int count)` method instead but this is rare 7594 area-System.Runtime BitConverter: Write bytes to exisiting array "I moved this here from dotnet/coreclr#4142 because I was told this is the right place. Hello, are there any ambitions to provide an API to BitConverter that takes an exisiting `byte[]` and position to include the bytes of a primitive? Right now I have an additional converter based on BitConverter that has methods like this: ``` c# /// /// Includes an int into an array of bytes /// public unsafe static void InsertBytes(int value, byte[] bytes, int index) { // Error handling and parameter validation if (bytes == null) throw new ArgumentNullException(nameof(bytes)); if (index + 4 > bytes.Length) throw new ArgumentOutOfRangeException(nameof(index)); fixed (byte* b = bytes) *((int*)(b + index)) = value; } /// /// Includes a long into an array of bytes /// [System.Security.SecuritySafeCritical] // auto-generated public unsafe static void InsertBytes(long value, byte[] bytes, int index) { // Error handling and parameter validation if (bytes == null) throw new ArgumentNullException(""bytes""); if (index + 8 > bytes.Length) throw new ArgumentOutOfRangeException(""index""); fixed (byte* b = bytes) *((long*)(b + index)) = value; } ``` I think it would be great to have those methods as well whenever we try to serialize values into an array without having to use `Array.Copy` all the time. To avoid redundant code the `GetBytes` methods should then just call the new methods. ``` c# // Converts an int into an array of bytes with length // four. [System.Security.SecuritySafeCritical] // auto-generated public unsafe static byte[] GetBytes(int value) { Contract.Ensures(Contract.Result() != null); Contract.Ensures(Contract.Result().Length == 4); byte[] bytes = new byte[4]; InsertBytes(value, bytes, 0); return bytes; } // Converts a long into an array of bytes with length // eight. [System.Security.SecuritySafeCritical] // auto-generated public unsafe static byte[] GetBytes(long value) { Contract.Ensures(Contract.Result() != null); Contract.Ensures(Contract.Result().Length == 8); byte[] bytes = new byte[8]; InsertBytes(value, bytes, 0); return bytes; } ``` I would be happy to submit a PR once this was reviewed and approved.

As this check is also slow, so I've added a cache to make sure we only do this once for each type. - ~~Internally dictionaries are handled as collection of KeyValues.

The System.Net.Http API surface consists of several classes. All of the implementation also lives in the .NET Framework as mostly a standalone implementation DLL (System.Net.Http.dll). Some functionality depends on low level APIs (such as HttpWebRequest) that lives in System.dll As part of updating the contract to 4.1, we are also OOB'ing the Desktop (net46 Windows) implementation so that the package won't be a facade over Desktop but rather a full implementation. As part of this, we are changing the implementation used for Desktop from the legacy HttpWebRequest sockets stack to the WinHttpHandler stack based on native WinHTTP. This will give us a good path forward as WinHttpHandler stack will be getting HTTP/2.0 support with newer versions of Windows 10. Since we are OOB'ing the DLL, we are able to add surface area as regular properties and not be forced to use extension methods (which wouldn't work in this case anyways). .NET Framework (Desktop) developers will only get this new implementation and expanded API set when they consume the NuGet package. Otherwise .NET Framework (Desktop) developers will get the existing inbox implementation. ## Proposed API ``` c# namespace System.Net.Http { // Other classes already part of System.Net.Http 4.0 contract ... public partial class HttpClientHandler : System.Net.Http.HttpMessageHandler { // // Existing methods and properties. // public HttpClientHandler() { } public bool AllowAutoRedirect { get; set; } public System.Net.DecompressionMethods AutomaticDecompression { get; set; } public System.Net.Http.ClientCertificateOption ClientCertificateOptions { get; set; } public System.Net.CookieContainer CookieContainer { get; set; } public System.Net.ICredentials Credentials { get; set; } public int MaxAutomaticRedirections { get; set; } public long MaxRequestContentBufferSize { get; set; } public bool PreAuthenticate { get; set; } public System.Net.IWebProxy Proxy { get; set; } public virtual bool SupportsAutomaticDecompression { get; } public virtual bool SupportsProxy { get; } public virtual bool SupportsRedirectConfiguration { get; } public bool UseCookies { get; set; } public bool UseDefaultCredentials { get; set; } public bool UseProxy { get; set; } protected override void Dispose(bool disposing); protected internal override System.Threading.Tasks.Task SendAsync(System.Net.Http.HttpRequestMessage request, System.Threading.CancellationToken cancellationToken); // // New properties. // public bool CheckCertificateRevocationList { get; set; } // Wanted to have this property be on type 'X509Certificate2Collection' but conflicts // with derived class WebRequestHandler in .NET Framework of the same property name. public System.Security.Cryptography.X509Certificates.X509CertificateCollection ClientCertificates { get; set; } // Wanted to have this property be called 'ServerCertificateValidationCallback` but // that name would conflict the derived class WebRequestHandler in .NET Framework // where the property is of a different type. public System.Func ServerCertificateCustomValidationCallback { get; set; } public System.Net.ICredentials DefaultProxyCredentials { get; set; } public int MaxConnectionsPerServer { get; set; } public int MaxResponseHeadersLength { get; set; } public System.Security.Authentication.SslProtocols SslProtocols { get; set; } // Generic property bag to that would allow for additional properties to be set and recognized by particular implementations (i.e. Windows vs. Unix, Unix-only connection socket options, etc.) public System.Collections.Generic.IDictionary Properties { get; } } } ``` ## Open Questions / Issues - There is an existing .NET Framework type, `System.Net.Http.WebRequestHandler` that lives in `System.Net.Http.WebRequest.dll`. `WebRequestHandler` derives from `HttpClientHandler`. And `WebRequestHandler` already has these properties on the type: ``` c# public System.Security.Cryptography.X509Certificates.X509CertificateCollection ClientCertificates { get; set; } public RemoteCertificateValidationCallback ServerCertificateValidationCallback { get; set; } ``` ## Usage The new HttpClientHandler properties being considered are currently already in the System.Net.Http.WinHttpHandler contract, as properties of the WinHttpHandler class. That contract is only implemented on Windows. For reference, all the System.Net.\* APIs were previously reviewed including WinHttpHandler: https://github.com/dotnet/apireviews/pull/21 Pending the 4.1 System.Net.Http review, the WinHttpHandler contract is being considered for removal from CoreFx final RTM contracts since it will be duplicative to the revised System.Net.Http 4.1 contract. 7626 area-System.Net Initial System.Net.Http 4.1 contract To support important customer scenarios for CoreFx RTM, we will be updating the System.Net.Http contract from 4.0 to 4.1. We are focusing on HttpClientHandler enhancements. We will be submitting the final proposed list of additions as part of issue #7623. As part of updating the contract to 4.1, we are also OOB'ing the Desktop (net46 Windows) implementation so that the package won't be a facade over Desktop but rather a full implementation. This is possible since System.Net.Http has always been a standalone dll in the .NET Framework. As part of this, we are changing the implementation for Desktop from the legacy HttpWebRequest sockets stack to the WinHttpHandler stack based on native WinHTTP. This will give us a good path forward as WinHttpHandler stack will be getting HTTP/2.0 support with newer versions of Windows 10. This initial PR has a few API additions that we are definitely going to be adding. It's important to get these changes into the builds so that we can fully bake the OOB Http.dll assembly on all the platforms and continue package testing. There is an existing System.Net.Http.WebRequestHandler class in the .NET Framework located in System.Net.Http.WebRequest.dll. This class is a subclass of HttpClientHandler. Due to this, we are being careful not to cause collisions with some of these added properties. WebRequestHandler has a 'ClientCertificates' property and a 'ServerCertificateValidationCallback' property. So, we are aligning/renaming the properties as we add them to HttpClientHandler OOB assembly. This may get altered slightly as we finalize the 4.1 System.Net.Http API. 7630 area-System.Diagnostics EventListener.DisposeOnShutdown crash due to collection modified during enumeration "http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/windows_nt_debug/1206/consoleFull ``` 10:51:06 System.InvalidOperationException: Collection was modified; enumeration operation may not execute. 10:51:06 at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) 10:51:06 at System.Collections.Generic.List`1.Enumerator.MoveNextRare() 10:51:06 at System.Diagnostics.Tracing.EventListener.DisposeOnShutdown(Object sender, EventArgs e) 10:51:06 d:\j\workspace\windows_nt_debuge57bf35e\Tools\tests.targets(147,5): warning MSB3073: The command ""xunit.console.exe System.Globalization.Calendars.Tests.dll -xml testResults.xml -notrait Benchmark=true -notrait category=OuterLoop -notrait category=failing -notrait category=nonwindowstests "" exited with code 1. ``` " 7633 area-System.Net Use exception filters in StreamFramer Contributes to #7632. cc @stephentoub @bartonjs 7634 area-System.Linq Would it be possible to remove some of the LowLevel* classes? As I understand it, the purpose of the `LowLevel*` classes in `Common` (such as [`LowLevelEnumerable`](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Linq/LowLevelEnumerable.cs)) is to avoid a dependency on `System.Linq` or `System.Collections`, while still being able to use features from the collection classes. Unfortunately, they have to be maintained in tandem with their counterparts and as a result are more poorly optimized (e.g. [this](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Linq/LowLevelEnumerable.cs#L33) naïve implementation of `Select`, vs. [this](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Select.cs#L12) one). Would it be possible to move the actual sources for the collection classes into `Common`, and a partial class that simply pointed people looking for the code to the `Common` folder? For example, we do this with `Debug` today; the actual source is [here](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Diagnostics/Debug.cs) in `Common`, while the file in `System.Diagnostics` is just there to [define public visibility](https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.Debug/src/System/Diagnostics/Debug.Public.cs). cc @stephentoub @JonHanna 7635 area-System.IO NamedPipeClientStream poorly handles the case where the pipe does not exist NamedPipeClientStream waits when the pipe does not exist, and it waits by spinning: ``` // Some platforms may return immediately from TryConnect if the connection could not be made, // e.g. WaitNamedPipe on Win32 will return immediately if the pipe hasn't yet been created, // and open on Unix will fail if the file isn't yet available. Rather than just immediately // looping around again, do slightly smarter busy waiting. sw.SpinOnce(); ``` This is problematic for two reasons. 1. I typically do not want to wait if the pipe does not exist; I only want to wait if the pipe is busy. This is because if the pipe doesn't exist, the server is probably not running, so waiting is unlikely to resolve anything. 2. Spinning on file not found consumes an entire CPU waiting for a service to start. Not a good choice. This combination of problems basically makes timeouts larger than a few milliseconds useless if there is any risk that the pipe will not exist. To fix this, I would propose two things: 1. Stop spinning. Sleep for a short time if you must poll. 2. Provide an option to fail if the pipe does not yet exist. Frankly I think this should be the default, but there are probably compatibility implications of this. 7636 area-System.Net Convert BidirectionalDictionary to be a struct Similarly to #7559, since `BidirectionalDictionary` is a type with all-readonly fields (and is always <= 16 bytes, even on 64-bit platforms), it's optimal for being converted to a struct.

"It's common when parsing strings to need a specific element from a parsed string. Currently, String.Split returns a fully parsed array of all the values, whether the developer needs them all or not. It would very useful to return a IEnumerable that can be used in a Linq expression. Then this can be done: string csv = ""Bill, Gates, One Microsoft Way, Redmond, WA, 98052""; var lastName = csv.EnumerateString(',').Take(2).Last(); The function would not need to fully parse the string if it is done after the second item, in this example.

" 7660 area-System.ComponentModel ComponentModel attributes that assist in altering data for integrity "It's been asked, [how data annotations can change data](http://stackoverflow.com/questions/51269), and [replace](http://stackoverflow.com/questions/15541199) or [trim](http://stackoverflow.com/questions/2864343/) property values. I don't feel annotations should be used in this way, but there could be benefit in attributes that would preform common and simple tasks that do alter data. These attributes might appropriately be called mutation attributes, which could include: Trim, Replace, RegexReplace, EnsureCase, etc. ### Simple Example It's common that models will trim whitespace form string properties and change empty strings to null. ``` csharp public class User { private string _firstName; public string FirstName { get { return _firstName; } set { value = value.Trim(); _firstName = String.IsNullOrEmpty(value) ? null : value; } } } ``` This could be the business requirement for all string properties of the user class. With mutation attributes this could be shortened drastically. ``` csharp public class User { [Trim, ToDefaultValue("""")] public string FirstName { get; set; } } ``` ### Advanced Example Let's assume we have sign up screen that accepts a username and password, and a model that annotates `User.UserName` as accepting any alphanumeric string including underscores as valid characters. Should the end-user enter `m@x_speed.01` as their desired username, validation would cause exceptions. Then the program should give an appropriate error message: ""Username must contain only alphanumeric character and underscores"". However if the designer would provide mutation attributes, the program could try to determine a valid value from the input. We could then provide a better message to the user: ""That username is invalid. Would you like to use 'mx_speed01' instead?"" ### Proposed API ``` csharp namespace System.ComponentModel.DataMutations { // Describes the context in which mutation is performed. // It supports IServiceProvider so that custom mutation code can acquire additional services to help it perform its mutation. public interface IMutationContext : IServiceProvider { object ObjectInstance { get; } IDictionary Items { get; } IEnumerable Attributes { get; } } // Describes the context in which mutation is performed. // T: The type to consult during mutation. public sealed class MutationContext : IMutationContext { // Constructors public MutationContext(T instance, IDictionary items) : this(instance, items, null); public MutationContext(T instance, IServiceProvider serviceProvider) : this(instance, null, serviceProvider); public MutationContext(T instance, IDictionary items, IServiceProvider serviceProvider) : this(instance); public MutationContext(T instance); // Properties public T ObjectInstance { get; } object IMutationContext.ObjectInstance { get; } public IDictionary Items { get; } public IEnumerable Attributes { get; } // Methods public void InitializeServiceProvider(Func serviceProvider); public object GetService(Type serviceType); } // Helper class to validate objects, properties, and other values using their associated MutationAttributes and custom mutation as implemented through the IMutableObject interface. public static class Mutator { // Mutate Value public static T Mutate(this MutationContext context, IEnumerable attributes) => typeof(T).GetTypeInfo().IsValueType ? // Mutate as value : // Mutate as object; public static T Mutate(this MutationContext context, IEnumerable attributes, T value) where T : struct; // Mutate Object public static T Mutate(this MutationContext context) where T : class; public static T Mutate(this MutationContext context, T instance) where T : class; public static T Mutate(this MutationContext context, T instance, IEnumerable attributes) where T : class; // Mutate Property public static object MutateProperty(this MutationContext context, PropertyInfo property) where T : class; public static P MutateProperty(this MutationContext context, PropertyInfo property, P value) where T : class; public static P MutateProperty(this MutationContext context, Expression> property) where T : class; public static P MutateProperty(this MutationContext context, Expression> property, P value) where T : class; } // Describes custom mutation logic that should be preformed on an object during mutation. public interface IMutableObject { void Mutate(IMutationContext context); } // Base class for all mutation attributes. public abstract class MutationAttribute : Attribute { // Properties public virtual bool RequiresContext { get; } public virtual int Priority { get; set; } // Methods public object Mutate(object value, IMutationContext context = null); protected abstract object MutateValue(object value, IMutationContext context); } // Trim Provides as sample implementation of MutationAttribute [AttributeUsage(AttributeTargets.Property, AllowMultiple = true)] public class TrimAttribute : MutationAttribute { // Constructors public TrimAttribute(params char[] characters); // Properties public char[] Characters { get; private set; } public TrimOptions Direction { get; set; } // Methods protected override object MutateValue(object value, IMutationContext context); } } ``` #### Implemented as Proposed Time has been spent on an implementation as it was needed for a project.

I will continue to update the repo according to this issue. **Source:** [roydukkey/Dado.ComponentModel.Mutations](https://github.com/roydukkey/Dado.ComponentModel.Mutations) **MyGet:** http://www.myget.org/gallery/roydukkey #### Updates 1. Add Attributes property to IMutationContext 2. Add Priority property to MutationAttribute - Without a priority `[DefaultValue(""~/data/""), Trim, ToDefaultValue("""")] string path { get; set; } = "" "";` will have a different result than `[DefaultValue(""~/data/""), ToDefaultValue(""""), Trim] string path { get; set; } = "" "";`. - This will get even messier when inheritance is introduced.

" 7688 area-System.Security Add support for import\export and named Crypto Elliptic Curves (API review) "Currently, both .NET 4.6 and .NET Core support only three Elliptic Curves (nistP256, nistP384 and nistP521). There have been requests to add additional curves and to add the ability to import and export parameters similar to how RSA and DSA already have. The proposed API additions are intended for both .NET 4.6.3 and for .NET Core rtm. For .NET Core, both Windows (via [Cryptograph Next Generation or CNG](https://msdn.microsoft.com/en-us/library/windows/desktop/mt632245%28v=vs.85%29.aspx)) and Linux\OSX (via [OpenSsl](https://wiki.openssl.org/index.php/Elliptic_Curve_Cryptography)) are to be supported. ## Rationale and Usage The current implementation has three curves selected by providing their key size (as an integer). However, this is no longer tenable as there are many curves (of different algorithms) that have the same keysize. Instead, a curve should be represented by a well-known Oid. Using named curves enables direct access to the curves supported by the underlying platform and thus does not require additional .NET framework code or public APIs to be added or changed in order to accommodate new curves (in most cases), although adding helper methods to pre-define the Oids may be desired. Using named curves in this way is consistent with both CNG and OpenSsl. In some cases, however, a curve name may not be known by the underlying platform, or a custom curve is desired. In that case, 'explicit' curves are desired which means all domain parameters are explicitly specified instead of being implied by the curve name. An explicit curve is abstract, contains common domain parameters, and is derived from by Prime and Characteristic-2 where each adds an additional domain parameter. The logical hierarchy:            Curve (abstract)             /      \ Named       Explicit (abstract)                    /        \               Prime   Characteristic-2 Note that this logical hierarchy is collapsed into a single struct called ECCurve. This was based on previous API review where class minimization was desired. ## Pull Request Current code is located [here](https://github.com/steveharter/dotnet_corefx/tree/Crypto) with pull request for code review [here](https://github.com/dotnet/corefx/pull/6789). ## High Level Programming Model (platform independent) The most common scenario is to instantiate an instance of [ECDsa](https://msdn.microsoft.com/en-us/library/system.security.cryptography.ecdsa%28v=vs.110%29.aspx) by passing in the name of the curve, and then sign some data or perform other action such as import, export and generate key. ECDsa is abstract, and the concrete dervived class depends upon the platform. For Windows, that is ECDsaCng and for Linux\OSX that class is ECDsaOpenSsl. Work is in progress to allow static Create factory methods to be directly on ECDsa in order to better support platform independent code by removing the need to instantiate the ECDsaCng or ECDsaOpenSsl directly. With that additional work, the programming model is: ``` c# using (ECDsa ec = ECDsa.Create(ECCurve.NamedCurves.nistP256)) { // sign some data, etc. ``` NamedCurves is a nested class under ECCurve, and nistP256 is a static factory method. Other Create() overloads include using the ECParameters class which contains the public and private key as well as a curve: ``` c# ECParameters parameters = ... using (ECDsa ec = ECDsa.Create(parameters)) { // sign some data, etc. ``` and the empty constructor: ``` c# using (ECDsa ec = ECDsa.Create()) { ec.GenerateKey(ECCurve.NamedCurves.brainpoolP256r1); // sign some data, etc. ``` The empty constructor will lazily-create a 521-bit nist curve when the key is first accessed (for backwards compatibility as that it what the constructor on derived classes do). This Create() is useful when the curve is not known at the time of creation and instead can be passed in later during GenerateKey() as shown in the example above. ## High Level Programming Model (platform dependent) The previous programming model examples include the static Create() methods on the abstract ECDsa base class. The examples below show usage of ECDsaCng directly which means the code is tied to a particular platform. ECDsaOpenSsl is not shown however it has the same examples as below, although the Cng and OpenSsl classes do differ in other public members not shown below. The current (but now considered obsolete) programming model using key size as integer: ``` c# // Use nistP256 (one of three supported curves) using (var ec = new ECDsaCng(256)) { // sign some data, etc. ``` The proposed programming model (using NamedCurves factory helper methods): ``` c# using (var ec = new ECDsaCng(ECCurve.NamedCurves.nistP256)) { // sign some data, etc. ``` The curve name can also be provided directly through using an Oid FriendlyName: ``` c# using (var ec = new ECDsaCng(ECCurve.CreateFromFriendlyName(""nistP256""))) { // sign some data, etc. ``` or by using an Oid Value: ``` c# using (var ec = new ECDsaCng(ECCurve.CreateFromValue(""1.2.840.10045.3.1.7""))) { // sign some data, etc. ``` or by using an instance of the Oid class directly: ``` c# using (var ec = new ECDsaCng(ECCurve.CreateFromOid(new Oid(""1.2.840.10045.3.1.7"", ""nistP256"")))) { // sign some data, etc. ``` ## ECCurve Namespace: System.Security.Cryptography.Algorithms Assembly: System.Security.Cryptography.Algorithms.dll This type serves several purposes: 1) Creation. Expose strongly-typed static helper methods to create an instance. 2) Domain Parameters. Contains the domain parameters for a named or explicit curve. For a named curve it uses an [Oid](https://msdn.microsoft.com/en-us/library/system.security.cryptography.oid%28v=vs.110%29.aspx)). For explicit curves it contains several domain parameters. 3) ECCurveType. It nests this class in order to hide it from the root of the namespace. ## ECCurve - Creation ``` c# /// /// An elliptic curve. /// /// /// The CurveType property determines whether the curve is a named curve or an explicit curve /// which is either a prime curve or a characteristic-2 curve. /// public struct ECCurve { /// Create a curve from the given cref=""Oid"". /// /// The Oid to use. /// An ECCurve representing a named curve. public static ECCurve CreateFromOid(Oid curveOid); /// /// Create a curve from the given cref=""Oid"" friendly name. /// /// The Oid friendly name to use. /// An ECCurve representing a named curve. public static ECCurve CreateFromFriendlyName(string oidFriendlyName); /// /// Create a curve from the given cref=""Oid"" value. /// /// The Oid value to use. /// An ECCurve representing a named curve. public static ECCurve CreateFromValue(string oidValue); /// /// Factory class for creating named curves. /// public static class NamedCurves { public static ECCurve brainpoolP160r1 {get;} public static ECCurve brainpoolP160t1 {get;} public static ECCurve brainpoolP192r1 {get;} public static ECCurve brainpoolP192t1 {get;} public static ECCurve brainpoolP224r1 {get;} public static ECCurve brainpoolP224t1 {get;} public static ECCurve brainpoolP256r1 {get;} public static ECCurve brainpoolP256t1 {get;} public static ECCurve brainpoolP320r1 {get;} public static ECCurve brainpoolP320t1 {get;} public static ECCurve brainpoolP384r1 {get;} public static ECCurve brainpoolP384t1 {get;} public static ECCurve brainpoolP512r1 {get;} public static ECCurve brainpoolP512t1 {get;} public static ECCurve nistP256 {get;} public static ECCurve nistP384 {get;} public static ECCurve nistP521 {get;} } ``` For named curves, only the friendly name or the value is required, not both, provided that the platform recognizes it, or if the other value can be determined. For CNG, the FriendlyName is eventually required. For OpenSsl, either will work however the FriendlyName values are not necessarily compatible or the same between Cng and FriendlyName for some curves. Using the Oid Value is preferred as it is stable across platforms although there are a handful of curves that only have the FriendlyName. Discussion topic: the set of static factory methods on NamedCurves are a subset of those from [Windows 10](https://msdn.microsoft.com/en-us/library/windows/desktop/mt632245%28v=vs.85%29.aspx). OpenSsl supports the nist curves, but not the brainpool, plus supports several additional (varies depending on OpenSsl version). RESOLUTION: this list was chosen because the nist and brainpool curves are likely to be the normally recommended curves. ## ECCurve - Domain parameters Elliptical curves contain [domain parameters](http://www.secg.org/sec1-v2.pdf) which are factored to support named curves and two types of explicit curves (Prime and Characteristic-2), to interop with CNG and OpenSsl. These types are used in cases where the parameters need to be provided to import\export and to generatekey. Currently CNG does not support Characteristic-2 curves. The ECCharacteristic2 class is present in the shared Algorithms assembly however -- i.e. it wasn't place in the OpenSsl-only assembly. Note: most of the parameter types are opaque and represented by byte[], even though they could be better represented by BigInteger or a standard integer in some cases. The rationale is because RSA also does this and because we do not expose all of the functionality that CNG or OpenSsl does regarding these types. In addition byte[] preserves the big-endian byte ordering of CNG and OpenSsl, unlike BigInteger. Discussion Topic Fields with public getter and setters are used as that is consistent with other types like RSAParameters. The alternative is to use properties with private setters and to provide additional Create() methods to specify all domain parameters for explicit curves. ``` c# public struct ECCurve { /// /// Coefficient A. Applies only to Explicit curves. /// public byte[] A; /// /// Coefficient B. Applies only to Explicit curves. /// public byte[] B; /// /// Base Point. Applies only to Explicit curves. /// public ECPoint G; /// /// Order of the group generated by G = (x,y). Applies only to Explicit curves. /// public byte[] Order; /// /// Cofactor (optional). Applies only to Explicit curves. /// public byte[] Cofactor; /// /// Seed of the curve (optional). Applies only to Explicit curves. /// public byte[] Seed; /// /// Curve Type. /// public ECCurveType CurveType; /// /// The hash algorithm used to generate A and B from the Seed. Applies only to Explicit curves. /// public HashAlgorithmName? Hash; /// /// The binary polynomial. Applies only to Characteristic2 curves. /// public byte[] Polynomial; /// /// The prime specifying the base field. Applies only to Prime curves. /// public byte[] Prime; /// /// The Oid representing the named curve. Applies only to Named curves. /// /// A clone is returned, not the current instance. public Oid Oid {get; private set} /// /// Validate the current curve. /// /// /// if the curve parameters are not valid for the current CurveType. /// public void Validate(); public bool IsPrime {get;} public bool IsCharacteristic2 {get;} public bool IsExplicit {get;} public bool IsNamed {get;} ``` ECCurve.Oid is immutable, even though the underlying Oid object is not (the Value and FriendlyName properties are settable). This is achieved by making a clone of the Oid during creation of the curve and making a clone of the Oid when the property getter is called. This simplifies usage of the classes that use ECCurve as they don't have to concern themselves with making their own copies of the Oid because the immutability prevents the Value or FriendlyName properties from changing afterwards by someone holding a reference to the Oid. ## ECCurve - nested ECCurveType This enum is used to identify the curve type, and during execution pass to CNG or OpenSsl to identify which explicit algorithm to use. The Prime\* values match a CNG native enum. Characteristic2 is only supported by OpenSsl. ``` c# public struct ECCurve { /// /// Represents the type of an elliptic curve. /// public enum ECCurveType : int { Implicit = 0, PrimeShortWeierstrass = 1, PrimeTwistedEdwards = 2, PrimeMontgomery = 3, Characteristic2 = 4, Named = 5, } ``` ## ECPoint ECPoint is used in ECParameters and ECCurve to represent a point on a curve. ``` c# /// /// Represents a point on an elliptic curve. /// public struct ECPoint { public byte[] X; public byte[] Y; } ``` ## Compatibility Windows 10 added support for named curves, so on versions of Windows before 10, when attempting to use curves except for the 3 that were supported previously, a PlatformNotSupportedException is raised during execution. For versions of Windows <10, extra work has been peformed to ensure that the *named* curve APIs on ECCurve and import\export of named curves work with the 3 curves. Even though named curves were not added until Windows 10, this was accomplished by mapping the names of the 3 curves to individual integer-based curve identifiers used in the older versions of CNG that work Discussion topic Note that _explicit_ curve import\export does not work on these 3 curves in < Windows 10 because that requires Windows 10 features. However it is possible that we hard-code the explicit curve values for the 3 curve values and get that to work if we decided that was worth the effort; this would mean that we hard-code the ECPrimeCurve values for those 3 curves. It is probably not worth the effort because the main scenario for using explicit import\export is to import a custom curve that does not have a name, or does not have a name known by the current platform, so it does not apply to the 3 curves. Windows does not support any Characteristic-2 curves, unlike OpenSsl. None of the Characteristic-2 curves (or in general OpenSsl-only curves) were added as helper factory methods to ECCurve. OpenSsl curve support varies by version, so some curves may work one version of OpenSsl but not another. PlatformNotSupportedException is thrown in such cases. Discussion topic: no [obsolete] keywords have been added in cases where the three existing curves are currently exposed on CngAlgorithm, or when keysize is used in the ECDsaCng and ECDsaOpenSsl constructors. RESOLUTION: obsolete is no longer used Discussion topic: no API has been added to determine if a curve is valid for a platform. Users must use try\catch. It is possible to add such as API. Also, the Oid class cannot be relied upon for determining such status as internally we maintain a global hard-coded mapping between Oid values and friendly names, and because some curves have an friendly name but no value and the Oid class cannot help resolve or verify the friendly name in such cases. RESOLUTION: address later, if at all. Additional work has also been done to ensure that values exported from Windows and OpenSsl have the same validation requirements. When importing, CNG requires the byte[] values of some properties to match, however OpenSsl doesn't. So there has been additional padding and max() calculations added to the OpenSsl side to match the Windows side. This enables better interop in cross-plat user code, at the expense however of those who may use OpenSsl APIs directly and are not constrained by those additional validation checks otherwise. ## ECParameters. This type is used during import\export to specify the public key, optional private key, and curve parameters. ``` c# /// /// Represents the public and private key of the specified elliptical curve. /// public struct ECParameters { /// /// Public point. /// public ECPoint Q; /// /// Private Key. Not always present. /// public byte[] D; /// /// The Curve. /// public ECCurve Curve; } ``` ## Import \ Export \ GenerateKey Namespace: System.Security.Cryptography.Algorithms Assembly: System.Security.Cryptography.Algorithms.dll These methods are overridden in ECDsaCng and ECDsaOpenSsl classes and for .NET 4.6.3 also the ECDiffieHellman class. ``` c# public abstract class ECDsa : AsymmetricAlgorithm { public static ECDsa Create(); public static ECDsa Create(ECCurve curve); public static ECDsa Create(ECParameters parameters); /// /// When overridden in a derived class, exports the named or explicit ECParameters for an ECCurve. /// If the curve has a name, the Curve property will contain named curve parameters otherwise it will contain explicit parameters. /// /// true to include private parameters, otherwise, false. /// public virtual ECParameters ExportParameters(bool includePrivateParameters); /// /// When overridden in a derived class, exports the explicit ECParameters for an ECCurve. /// /// true to include private parameters, otherwise, false. /// public virtual ECParameters ExportExplicitParameters(bool includePrivateParameters); /// /// When overridden in a derived class, imports the specified ECParameters. /// /// The curve parameters. public virtual void ImportParameters(ECParameters parameters); /// /// Generates the public and private key. /// /// The curve to use. /// public virtual void GenerateKey(ECCurve curve); ``` Note: not shown here, but ECDH, RSA and DSA are to add matching Create factory support to better support platform independent code.

Historically, in .NET Framework, there has been two distinct set of HTTP API:s: one for handling client scenarios (HttpClient), and another for server scenarios (HttpListener). Both are residing in the System.Net.Http namespace. Presently, there is no HttpListener in the .NET Core stack. It made me to build my own: https://github.com/robertsundstrom/HttpListener I wonder if there are any plans to implement the HttpListener API further down the road. In any case, I have a suggestion for that: Merge the two API:s so that they share a common base and common constructs like: HttpRequestMessage, HttpResponseMessage, etc. This would mean that the HttpClient sends an HttpRequestMessage, and the HttpListener should give a HttpRequestMessage. The content should be virtually the same in each end. Correspondingly, the HttpListener would send a HttpResponseMessage back, and the client would receive a HttpResponseMessage. In this way we get a more flexible API that is also easier to use, because the developers do not have to handle two sets of what actually could be the same thing. 7707 area-System.Net NegotiateStream_StreamToStream_AuthToHttpTarget_Success test failing on RHEL http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/outerloop_rhel7.2_release_tst/47/consoleFull ``` 08:18:40 System.Net.Security.Tests.KerberosTest.NegotiateStream_StreamToStream_AuthToHttpTarget_Success [FAIL] 08:18:40 System.AggregateException : One or more errors occurred.

Exit code 1. 7714 area-System.Net Fix HttpClient dependencies on desktop The latest changes to make HttpClient an OOB implementation on desktop were not getting the correct dependency set. This has to do with the the way that EnsureOOBFrameworks evaluates assets to duplicate. It does so by seeing if any placeholders are obscuring the netstandard asset and copying the netstandard asset if that is the case. This worked fine for the reference assembly, but not the implementation since it wasn't actually obscured. The result was that NuGet selects the correct assets, but is missing implementation dependencies. For now I'm fixing this by changing the package structure to explicitly break out the net46 implementations into their own folders. This is essentially what we were trying to make happen automatically with EnsureOOBFrameworks. Longer term we might want to refactor how we generate dependencies to do an actual nuget-asset selection in order to harvest from the actual assemblies that NuGet will choose. For now I'm also working around the problem that the unix shims are being referenced everywhere even though they're only needed for Unix. There's still a problem with this package in that we have two different netstandard dependency groups (one meant for Windows and one meant for Unix) but because we can't express that in a fat package the Unix one will win, even on a windows machine, if the target framework supports NETStandard1.4 or higher. This doesn't cause a problem at the moment because the unix implementation is using a superset of the Windows dependencies but we need to see about how to better handle in lieu of the NuGet feature for RID-specific dependencies. /cc @davidsh @weshaggard @chcosta 7719 area-System.Linq LINQ: Append/Prepend/Cast could probably be optimized Currently, the implementation for `Append` looks like this: ``` cs public static IEnumerable Append(this IEnumerable source, T value) { foreach (var item in source) yield return item; yield return value; } ``` This looks like it's missing out on chances for optimization. For example, this code could probably be optimized if `items` was an array/list: ``` cs items.Append(foo).ToArray(); ``` since we'd know that the result would have a length of exactly `items.Length + 1`. Same for this: ``` cs items.Append(foo).Count(); ``` cc @JonHanna --- **edit:** Also `Cast` too, since the number of elements in the resulting enumerable is guaranteed to have the same number of items as the source. Today we still naively use an iterator block like this: ``` cs public static IEnumerable Cast(this IEnumerable source) { foreach (object obj in source) yield return (T)obj; } ``` 7720 area-System.Threading Add some basic Monitor tests.

Since OpenSSL has the BIO type to handle payload buffering it isn't set up to report the header and footer sizes the same way SChannel is. So, let the PAL implementation change the output buffer if it wants it to be bigger. The Windows implementation is largely unchanged, the only difference being that the Buffer.BlockCopy that aligns the data for SChannel interpretation has moved into the PAL. The Unix implementation doesn't need that extra copy to happen, so there's even a mild perf gain here. Fixes #7599.

Why it can't be exposed? Best 7750 area-System.Net HttpClient and Cookies not working with redirects under netcore50 "I have a test project that uses an HTTP-Client to connect to a service, which in term uses cookies to store user information. Once done, it performs a redirect. Here's the service API: ``` [HttpGet] [Authorize(ActiveAuthenticationSchemes = ""Cookies"")] [Authorize(ActiveAuthenticationSchemes = ""Bearer"")] public async Task SelectTenant([FromQuery]string tenant) { ... var identity = (ClaimsIdentity) User.Identity; identity.AddClaim(new Claim(""foo"", bar)); // sign in again to persist the new claim in the cookie await HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, User); // redirect to the index (which won't realize we just logged in on DNX Core) return Redirect(""/""); } ``` Now, when on dnx451, the code works just fine. The index page is invoked, recognizes the cookie and the caller (HttpClient) also gets the cookie information. However, as soon as I switch to netcore50, the redirect isn't working properly anymore, as authentication data (in the cookie) seems to be lost. This is happening **before** `GetAsync` returns control to me. Here is the console output when running on DNX Core as of the redirect. Note that server-side authorization failed after the redirect: ``` info: Microsoft.AspNet.Authentication.Cookies.CookieAuthenticationMiddleware[3] AuthenticationScheme: Cookies signed in. 2016-04-14 18:43:15 [Information] Executing RedirectResult, redirecting to ""/"". info: Microsoft.AspNet.Mvc.RedirectResult[1] Executing RedirectResult, redirecting to /. 2016-04-14 18:43:15 [Information] Executed action ""OrderManager.Controllers.AccountController.SelectTenant"" in 0.0016ms info: Microsoft.AspNet.Mvc.Infrastructure.MvcRouteHandler[2] Executed action OrderManager.Controllers.AccountController.SelectTenant in 0.0016ms 2016-04-14 18:43:15 [Information] Request finished in 0.0016ms 302 info: Microsoft.AspNet.Hosting.Internal.HostingEngine[2] Request finished in 0.0016ms 302 2016-04-14 18:43:15 [Information] Protocol: HTTP/1.1 Method: GET ContentType: ContentLength: Scheme: http Host: localhost:5000 PathBase: Path: / Quer yString: info: Microsoft.AspNet.Hosting.Internal.HostingEngine[1] Request starting HTTP/1.1 GET http://localhost:5000/ 2016-04-14 18:43:15 [Warning] Authorization failed for the request at filter '""Microsoft.AspNet.Mvc.Filters.AuthorizeFilter""'. warn: Microsoft.AspNet.Mvc.Controllers.ControllerActionInvoker[0] Authorization failed for the request at filter 'Microsoft.AspNet.Mvc.Filters.AuthorizeFilter'. 2016-04-14 18:43:15 [Information] AuthenticationScheme: ""Cookies"" was challenged. info: Microsoft.AspNet.Authentication.Cookies.CookieAuthenticationMiddleware[5] AuthenticationScheme: Cookies was challenged. 2016-04-14 18:43:15 [Information] Executing ChallengeResult with authentication schemes ([""Cookies""]). info: Microsoft.AspNet.Mvc.ChallengeResult[1] Executing ChallengeResult with authentication schemes (Cookies). 2016-04-14 18:43:15 [Information] Executed action ""OrderManager.Controllers.HomeController.Index"" in 0.0015ms ``` It's worth noting that once control is returned to my code, HttpClient actually does get Cookies returned (just the wrong ones, since the Index page does another redirect to the logon because it doesn't realize I already logged in). So I guess that after `HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, User);` is executed, and the redirect happens, `HttpClient`on Core50 doesn't resubmit the cookie to the Index page or something. Here's the client call btw: ``` internal static async Task GetAuthCookie() { var c = new AuthenticationApiClient(new Uri(""https://foo.auth0.com"")); AuthenticationRequest request = new AuthenticationRequest { ... }; // authenticate with auth0 var authToken = await c.AuthenticateAsync(request); // set the authorization header var authHeader = new AuthenticationHeaderValue(""Bearer"", authToken.IdToken); var httpHandler = new HttpClientHandler(); using (var client = new HttpClient(httpHandler) { BaseAddress = new Uri(Settings.Uri) }) { client.DefaultRequestHeaders.Authorization = authHeader; string selectTenantUrl = ""Account/SelectTenant?tenant=bar""; //THIS IS THE CALL THAT DOESN'T WORK THE SAME ON CORE50 var result = await client.GetAsync(selectTenantUrl); Cookies = httpHandler.CookieContainer; } } ``` " 7751 area-System.Numerics Consider SIMD acceleration for Matrix and Quaternion operations similar to Vector ones Currently only Vector operations seem to benefit from SIMD acceleration. Matrix and Quaternion operations still use scalar operations instead. For instance, adding two Vector4 instances would emit a single instruction for packed addition, while transforming a Vector4 with a Matrix4x4 would result in 16 scalar multiplications and 12 scalar additions, instead of 4 packed multiplications and 3 packet additions. Since one of the main usage scenarios of System.Numerics.Vectors is in graphically intensive 2D and 3D applications, there are many cases where such applications can greatly benefit from accelerating Matrix and Quaternion operations. The theoretical speedup of a factor of 4 simply cannot be ignored. Some operations can be emulated by using Vector instead (e.g. Matrix4x4 can be represented with 4 Vector4 instances, so we can emulate the Matrix4x4 x Vector4 transformation by inlining the necessary code by hand), but other operations are hard or impossible to emulate efficiently. 7757 area-System.Globalization TimeZoneInfo should expose FromSerializedString and ToSerializedString `TimeZoneInfo` cannot be serialized with the data contract serializer (which is a recommended serialization API for .NET Core) - serializing it results in an `InvalidDataContractException`. An easy workaround would be to use `ToSerializedString` and `FromSerializedString` to convert the TimeZoneInfo into a string, but those APIs are also not available in .NET Core. This combination makes attempting to serialize a type containing a `TimeZoneInfo` a poor experience (the user needs to add a lot of `[KnownType]` attributes as per [this guidance](https://social.msdn.microsoft.com/Forums/en-US/f164f185-ae18-4775-a2ff-a814813d262d/unable-to-serialze-member-of-type-timezoneinfo?forum=wcf)) which results in messy code. 7758 area-System.ComponentModel Improve code coverage for System.ComponentModel.TypeConverter (24%) The code coverage report shows us at 47% for the next version of the package (currently in `dev/typedescriptor`).

Fixes #7505 7763 area-System.Net Convert static readonly fields in Uri to const Right now `Uri` has a bunch of `static readonly` string fields that represent different scheme names, e.g. `UriSchemeFile`. Presumably they correspond to [these](https://msdn.microsoft.com/en-us/library/system.uri_fields%28v=vs.110%29.aspx) fields on MSDN, but since they don't appear to be exposed in the contract (and thus aren't visible publicly), I've converted them to be `const` strings. Summary of full changes in this PR: - Converted `static readonly` fields -> `const` strings - Refactored `UriParser` to reference these constants during intialization of built-in URI parsers - Since a few of them were schemes that were not previously exposed as a field (e.g. `vsmacros`), I've added a few extra `const` strings (such as `UriSchemeVsMacros`) and moved the definitions to `UriParser` - Added a `using static` to `Uri` and `UriBuilder`, which previously referenced those constants cc @justinvp @hughbe @stephentoub 7765 area-Serialization Remove nongeneric collections shim from serialization Remove non-generic collections `ArrayList` and `InternalHashtable` and use ArrayList and generic dictionary instead.

It's a common scenario to want to return a cached `Task` if there's no async work that needs to be done in a method; .NET 4.6 offers `Task.CompletedTask` which helps with this, but for methods that actually return a result through the task there is no such alternative. Examples of where this would be useful: - `Stream.ReadAsync`: Classes that override `ReadAsync` can return `Task.Default()` instead of `Task.FromResult(0)` when there's no more work to do. - For any method returning `Task` where T is a reference type, if the return value is null then they can use `Task.Default()`. - Any method returning `Task.FromResult(false)` can use `Task.Default()` instead, which is likely a common scenario since there's only two boolean values. ## Proposed API ``` cs namespace System.Threading.Tasks { public class Task : IAsyncResult { public static Task Default(); } public class Task : Task { public static Task Default { get; } } } ``` 7800 area-System.Net Replace StreamAsyncHelper with StreamApmExtensions in System.Net.Security System.Net.Security was originally written to use Stream.Begin/EndRead/Write. When it was ported to .NET Core, it took a dependency on a helper that provided such Begin/End methods, but this helper was originally written for a different purpose: providing async Begin/End wrappers for the synchronous Read/Write methods. As a result of this mismatch, the async calls in System.Net.Security are queueing work items that then do work synchronously, blocking thread pool threads unnecessarily. This commit changes those helpers to sit on top of ReadAsync/WriteAsync instead. Eventually System.Net.Security should have its async I/O redone to sit natively on ReadAsync/WriteAsync using async/await, as it'll result in less overhead, but for now with minimal changes this improves the scalability of the library. cc: @davidsh, @cipop, @ericeil, @mikeharder 7804 area-System.Runtime Add UTF8 to CharSet The CharSet enumeration is used to specify how strings should be marshaled: https://github.com/dotnet/corefx/blob/master/src/System.Runtime/ref/System.Runtime.cs#L3019-L3023 ``` C# public enum CharSet { Ansi = 2, Unicode = 3, } ``` `Unicode` specifies that UTF16 should be used, regardless of platform, but `Ansi` is interpreted differently based on platform: on Windows it's interpreted to mean the ANSI format, whereas on Unix it's interpreted to mean UTF8. This means that on Windows we lack the ability to specify UTF8 as the marshaling, and more generally we lack the ability to specify UTF8 marshaling regardless of platform, making writing cross-platform managed components more difficult. We should add a new UTF8 enum value: ``` C# public enum CharSet { Ansi = 2, Unicode = 3, UTF8 = 5, } ``` that when used will cause the runtime's marshaling to be done with UTF8, which is the standard for modern services. [Added-by-Yi] We should also add a new corresponding UnmanagedType enum in UnmanagedType for UTF8 as well, for finer control and parity (between UnmanagedType and CharSet): https://github.com/dotnet/corefx/blob/master/src/System.Runtime.InteropServices.PInvoke/ref/System.Runtime.InteropServices.PInvoke.cs ``` C# public enum UnmanagedType { LPUTF8Str = 0x30 } ``` And new Marshal helpers while we are at it: ``` C# public class PInvokeMarshal { public static string PtrToStringUTF8(System.IntPtr ptr); public static string PtrToStringUTF8(System.IntPtr ptr, int len); public static System.IntPtr StringToAllocatedMemoryUTF8(string s); public static System.IntPtr ZeroFreeMemoryUTF8(System.IntPtr s); } ``` 7805 area-System.Runtime LoadInDefaultContext failed in CI with permissions error http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/ubuntu15.10_release_tst/15/console ``` 04:16:23 System.Runtime.Loader.Tests.DefaultLoadContextTests.LoadInDefaultContext [FAIL] 04:16:23 System.UnauthorizedAccessException : Access to the path '/tmp/System.Runtime.Loader.Noop.Assembly.dll' is denied. 04:16:23 ---- System.IO.IOException : Operation not permitted 04:16:23 Stack Trace: 04:16:23 Starting: System.Runtime.Loader.Tests 04:16:23 at System.IO.UnixFileSystem.DeleteFile(String fullPath) 04:16:23 at System.Runtime.Loader.Tests.DefaultLoadContextTests.Init() 04:16:23 at System.Runtime.Loader.Tests.DefaultLoadContextTests.LoadInDefaultContext() ``` 7806 area-System.Numerics Intermittent System.Numerics.Tests.divremTest.RunDivRemTests failed in CI on CentOS, Windows http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/outerloop_centos7.1_debug_tst/3/consoleFull ``` 00:29:07 System.Numerics.Tests.divremTest.RunDivRemTests [FAIL] 00:29:07 Assert.Throws() Failure 00:29:07 Expected: typeof(System.DivideByZeroException) 00:29:07 Actual: typeof(Xunit.Sdk.TrueException): Out parameters not matching 00:29:07 Expected: True 00:29:07 Actual: False 00:29:07 Stack Trace: 00:29:07 at System.Numerics.Tests.StackCalc.VerifyOutParameter() 00:29:07 at System.Numerics.Tests.divremTest.VerifyDivRemString(String opstring) 00:29:07 at System.Numerics.Tests.divremTest.<>c__DisplayClass8_0.b__0() ``` 7807 area-System.Threading 14 System.Threading.Tasks.Parallel tests failing in outerloop They all look similar to: ``` 00:32:12 System.Threading.Tasks.Test.ParallelState.ParallelState73 [FAIL] 00:32:12 Assert.IsType() Failure 00:32:12 Expected: System.InvalidOperationException 00:32:12 Actual: Xunit.Sdk.TrueException 00:32:12 Stack Trace: 00:32:12 at System.Threading.Tasks.Test.ParallelStateTest.RealRun() 00:32:12 at System.Threading.Tasks.Test.ParallelState.ParallelState73() ``` 7809 area-System.Collections Cleanup StringDictionary tests - Use xunit - Remove duplicate tests already covered - Remove unecessary tests 7810 area-System.Data Provider test suite for ADO.NET To promote standard behavior across ADO.NET providers, it would be great if a test suite existed.

The same set of expressions is also used in testing a no-op visitor. These are very time-consuming; removing them reduces run time from around 2m 50s on my machine to around 30s. They also give a false sense of coverage; a flaw within the expression itself would lead a correctly implemented compiler and interpreter to give the same incorrect result, so the coverage the tests lead to give a false impression of what branches are actually checked by tests. The drop in coverage makes it not a no-brainer clear win, but I think ultimately more of a boon toward the purpose of #1198 than the decrease in running time, even if it does take a step back in the metric. 7818 area-System.Diagnostics TestProcessStartTime failing on certain machines in CI This just started acting up again.

This commit ensures that such exceptions have a stack trace by throwing and catching them before storing them into either another exception as an inner exception or directly into a Task.

We will start with a Windows-only package (for time/cost reasons) but the package will be structured so that platform dependencies are isolated into a PAL layer and OpenSSL support can be added later. **Usage** The proposed api is designed to be source-compatible with the existing .NET feature (System.Security.Cryptography.Pkcs.EnvelopeCms) https://msdn.microsoft.com/en-us/library/system.security.cryptography.pkcs.envelopedcms(v=vs.110).aspx This is not intended to be an endorsement of that feature’s API design, rather an acknowledgement that easy source migratability remains a compelling feature. In addition to the EnvelopedCms type, we will migrate over the exchange types it needs. This represents the minimal set (despite its size.) ``` namespace System.Security.Cryptography { public sealed class CryptographicAttributeObject {} public sealed class CryptographicAttributeObjectCollection : ICollection, IEnumerable {} public sealed class CryptographicAttributeObjectEnumerator : IEnumerator {} } namespace System.Security.Cryptography.Pkcs { public sealed class AlgorithmIdentifier {} public sealed class CmsRecipient {} public sealed class CmsRecipientCollection : ICollection, IEnumerable {} public sealed class CmsRecipientEnumerator : IEnumerator {} public sealed class ContentInfo {} public sealed class EnvelopedCms {} public sealed class KeyAgreeRecipientInfo : RecipientInfo {} public sealed class KeyTransRecipientInfo : RecipientInfo {} public class Pkcs9AttributeObject : AsnEncodedData {} public sealed class Pkcs9ContentType : Pkcs9AttributeObject {} public sealed class Pkcs9DocumentDescription : Pkcs9AttributeObject {} public sealed class Pkcs9DocumentName : Pkcs9AttributeObject {} public sealed class Pkcs9MessageDigest : Pkcs9AttributeObject {} public sealed class Pkcs9SigningTime : Pkcs9AttributeObject {} public sealed class PublicKeyInfo {} public abstract class RecipientInfo {} public sealed class RecipientInfoCollection : ICollection, IEnumerable {} public sealed class RecipientInfoEnumerator : IEnumerator {} public enum RecipientInfoType {} public sealed class SubjectIdentifier {} public sealed class SubjectIdentifierOrKey {} public enum SubjectIdentifierOrKeyType {} public enum SubjectIdentifierType {} } namespace System.Security.Cryptography.Xml { public struct X509IssuerSerial {} } ``` **Compatibility** Nevertheless, we do propose to remove some of the harder-to-implement/troublesome surface area. **Senders must pass at least one CmsRecipient programmatically.** Unlike the full framework, we will not put up a dialog box for the user to select a certificate interactively. Passing an empty “recipients” argument to EnvelopedCms.Encrypt() will throw a PlatformNotSupportedException. Rationale: The dialog box is a disproportionally costly item to implement and may be irrelevant on Unix platforms (where we probably won’t automatically search a “MY store”) Our current asks have confirmed they do not require this feature. As part of this, we would remove the following method and constructor overloads: ``` EnvelopedCms.Encrypt() EnvelopedCms..ctor(SubjectIdentifierType recipientIdentifierType, ContentInfo contentInfo) EnvelopedCms..ctor(SubjectIdentifierType recipientIdentifierType, ContentInfo contentInfo, AlgorithmIdentifier encryptionAlgorithm) ``` The nullary Encrypt() message will always throw a PlatformNotSupportedException – making it useless. Passing a SubjectIdentifierType to the constructor is useless if the dialog box is unavailable, as that’s the only scenario in which this parameter’s value is used. Its very existence is confusing as the recipientIdentifierType is a per-recipient value, not a per-CMS value. **Remove the Parameter property from the AlgorithmIdentifier class.** Rationale: This property has two purposes: Extract the IV from a decoded CMS and to extract the key encryption algorithm parameters from the CMS. Unfortunately, the “IV” part has been plagued with problems from the start. For DES and 3DES, it returns a bogus value entirely. It only decodes the IV for mostly obsolete algorithms (RC2, RC4, DES and 3DES). For newer algorithms such as AES, it returns you an undefined encoded value. Since the result is a simple byte[] array, there is no way for the caller to know what he got back other than to know these idiosyncracies – nor can we easily fix them in a way that the caller can distinguish good returns from bad. The existence of the Parameters property also tricks one into thinking he can use it as an input to the EnvelopedCms constructor. But that assumption is wrong. EnvelopedCms’s constructor immediately zeroes out the Parameter property of the passed in AlgorithmIdentifier. (This is also rude API behavior as the mutation is visible to the caller.) Given all these historical problems, its vaguely defined nature and the fact that none of our asks need this information, we’d prefer to amputate this problem now. If a need for this information comes up in the future, we can take the opportunity to design the api better. Having said that, the philosophy for this iteration of the package is that we enable the basic encrypt/decrypt/decode scenarios. Supporting the writing of a full-fledged “CMS dumper” utility or attempting to decrypt the content yourself is a non-goal. **Turn IsSynchronized and SyncRoot on the Collection classes into methodimpls.** This has been an ongoing pattern as we port Collection classes. **Remove the finalizer from ContentInfo.** ContentInfo is nothing more than a tuple class that bundles an Oid and a byte array. There is no legitimate reason for it to hold native resources or contain any OS-specific code at all. The original desktop code threw an internal ""pin the byte array and give us a pointer to it"" helper method into it to solely to avoid three lines of ""pin the byte array and call the P/Invoke"" somewhere else.

And I just want to make sure that I'm not imagining... In posix based systems the async sockets actually queue work items into the ThreadPool, and the actual IO is performed in a synchronous (maybe non-blocking) manner? Is this right? I assume that this is a very big split from how things are done on a native win32 system... I would appreciate any sort of clarification on this matter from someone well aware of the actual implementation I also think the documentation could benefit from a more detailed explanation of how async I/O works in different scenarios (OS)... I would be more than happy to submit a PR for the documentation, but I just want to make sure I'm reading the situation the right way Basically people doing async IO need to be aware of how the .NET idioms map to the actual OS...

However, it allocates a lot of `Node`s which means in practice its generally better to use a ConcurrentQueue which is based on array chunks since if you are pooling you are trying to avoid the allocations. It allocates a [new Node for every Add](https://github.com/dotnet/corefx/blob/d0dc5fc099946adc1035b34a8b1f6042eddb0c75/src/System.Collections.Concurrent/src/System/Collections/Concurrent/ConcurrentBag.cs#L905). If for example it used a lockless `ThreadStatic` stack or queue for the `Node`s and recycled them this would reduce its allocation weight; while still having the low contention. (Might be better approaches, just a suggestion) The following code allocates 32M Nodes and 1,278,983,840 bytes ``` csharp var o = new object(); var bag = new ConcurrentBag(); for (var ii = 0; ii < 1000000; ii++) { for (var i = 0; i < 32; i++) { bag.Add(o); } for (var i = 0; i < 32; i++) { bag.TryTake(out o); } } ``` ![Node allocations](http://aoa.blob.core.windows.net/aspnet/concurrentbag1.png) /cc @stephentoub 7920 area-System.Reflection TypeExtensions does not contain GetConstructor, GetMethod which accepts both BindingFlags and a Type[] "For example: in the full framework you could obtain a protected constructor with a specific signature by using the ""Type.GetConstructor(BindingFlags, Binder, Type[], ParameterModifier[])"" method.

If you even read a single byte of the content, `Dispose` works just fine. `HttpCompletionOption.ResponseContentRead` is the default so this is perhaps a less common scenario. I have tested Mac OS X and Linux, which have the same results. Windows acts differently. ``` > dotnet --version 1.0.0-rc2-002345 ``` ### Use Case This is important because sometimes it's not necessary for a client application to read the response body (e.g. if the status code is `500 Internal Server Error` then perhaps the client does not care to download the response). ### Workaround The client can just read a single byte from the response. However this seems like a hack and could break in the future for all I know. ### Test procedure 1. Extract the following .NET CLI test app: [closehttp.zip](https://github.com/dotnet/corefx/files/228633/closehttp.zip) 2. Open a connection but don't read any content (`dotnet run` on the test app). 3. Use some other tool to see open TCP connections on the test app process and verify one exists. - `lsof` on OS X and Linux. - [Process Explorer](https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx) on Windows. 4. Dispose the connection by following the tool's prompts. (`HttpResponseMessage.Dispose`) 5. Expect the connection to be closed in the tool and verify in the tool used in step 3. 6. Repeat steps 2-5 with `dotnet run read` (or any command line argument) to read a byte of the content body. ### Mac OS X and Linux results Checking a process's TCP connections: ``` > lsof -p PID | grep TCP dotnet 49733 46u IPv4 0t0 TCP :50657->ec2-54-175-222-246.compute-1.amazonaws.com:http (ESTABLISHED) ``` `HttpResponseMessage.Dispose` only closes the connection if an attempt has been made to read from the content stream. Calling `Dispose` on the network stream (from `HttpResponseMessage.Content.ReadAsStreamAsync`) does not help. `HttpClient.Dispose` _does_ close the connections. ### Windows results Checking a process's TCP connections: Screenshot for Process Explorer. ![capture](https://cloud.githubusercontent.com/assets/94054/14687430/572239e4-06f2-11e6-8bfb-5b20dcf13d4d.PNG) `HttpResponseMessage.Dispose` never seems to close the connection. Calling `Dispose` on the network stream (from `HttpResponseMessage.Content.ReadAsStreamAsync`) does not help. `HttpClient.Dispose` _does_ close the connections. I am thinking this may be due to the fact that the underlying layer is doing some connection pooling or `Keep-Alive` stuff.

I'm author of [FsPickler](http://nessos.github.io/FsPickler/), a multi-format message serialization library intended as a replacement to BinaryFormatter. The focus of the library is _serialization of closures_, which means that I need to support things like subtyping and internal, compiler-generated classes that often have no accessible constructors or serialization attribute annotations. I would be interested in porting FsPickler (and its father project, [mbrace](http://mbrace.io/)) to CoreCLR, however there are many obstacles, mostly related to deprecated APIs. The component I'm more concerned about is the `FormatterServices.GetUninitializedObject` method which is used for instantiating objects without relying on a parameterless constructor. This is crucial for us since many closure types (particularly F# lambdas) do not come with such constructors. Do you have any plans for replacing this with equivalent functionality? /cc https://github.com/dotnet/corefx/issues/6564#issuecomment-212620200 https://github.com/dotnet/coreclr/issues/2715 7939 area-Infrastructure Update Windows Nano Server image used in CI cc @joshfree 7941 area-System.Net Fail more gracefully if the user specifies a receive buffer for AcceptAsync On Windows, `AcceptAsync` can optionally receive an initial buffer-full of data from the newly connected socket, via the magic of [`AcceptEx`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms737524%28v=vs.85%29.aspx). We currently have no emulation of this feature on Unix. Instead, we fail an assert in Debug builds, or report erroneous results in Release builds. This change causes `AcceptAsync` to throw `PlatformNotSupportedException` if the user has supplied a buffer to receive data. In the future, we can consider implementing this feature, but for now it's better to fail correctly rather than succeed erroneously. I've also added a couple of new test cases (to check that this works on Windows, and does _not_ work on Unix), and some new asserts to make sure this doesn't come up elsewhere. Addresses #7836 @stephentoub, @CIPop 7942 area-Serialization XmlDictionaryWriterTest.XmlBaseWriter_CheckAsync_ThrowInvalidOperationException Fails in Net Native The test asserts the exception message.

Because of how asynchronous transfers work, where we need to pause the connection until a reader has requested data, if no reader ever requested data (e.g. the stream was disposed without reading anything) then the connection could remain paused indefinitely, and it would sit around until the HttpClient timeout kicked in and canceled it. This could lead to unbounded growth of the number of sockets being used, as sockets couldn't be pooled or cleaned up due to still being associated with an active download. The fix is simply to cancel the request in Dispose if the request isn't already completed. cc: @ericeil, @kapilash, @davidsh, @joelverhagen 7947 area-System.Net Force CurlHandler active operations to shutdown when handler disposed If the CurlHandler is disposed of while active operations are in progress, fail them.

Summary of ideas on this (thanks @ericstj @mellinoe) This was found in https://github.com/dotnet/corefx/pull/7931. However, https://github.com/dotnet/corefx/issues/7902 indicated that there was a corrupted package in the NuGet cache, which suggests that some sort of interruption earlier caused a package to be corrupted during restore. It may have been this same kind of segfault during a package install that caused the corrupt package, but we don't have a good way of tracking this down. A simple `./build.sh managed release` doesn't repro the segfault on my OSX box. One thing to try is to update CLI to take any fixes to the runtime that might have happened. (Side effect: NuGet may also want to be resilient to corrupted cache files, in case segfaults or even just build cancellations happen when the cache is being written.) " 7953 area-System.Linq Lambda compilation causes a stackoverflow when selecting a large number of columns from an EF entity. "This has been moved from https://github.com/aspnet/EntityFramework/issues/5131 We have a bit of an odd use-case and I think I may have uncovered a bug. I am going to be as clear as I can, but please ask any questions you need for clarification. I know this bug (if it is a bug) isn't going to be fixed today, so if someone can point me to the location in source this might originating from, I can take a look and 1) see if I can fix it or 2) if it isn't a bug in EF adjust my code accordingly. #### Problem System.Stackoverflow exception originating from EntityFramework.dll is causing W3WP to crash. #### What we are trying to do We have an entity defined in a DB context - nothing out of the ordinary here. The entity is exposed over a WebAPI Odata endpoint. The web client is able to query the data just fine and exports it to CSV for customers to download. The view backing the entity in question is approaching 1 millions records. We have an SLA to meet when being able to export the CSV, and when you have to export 1million records this SLA is broken. We originally tried a multi-threaded approach by have X number of threads getting N number of records per page and each doing a specific number of pages. So, 5 threads running at a time, each responsible for 200,000 records paging through them at 100 each. This helped, but it would still take ~20 minutes for a full export. So we moved to a streaming approach - this is where the fun starts :) #### Repro steps 1) Create a view in a database with more than 100 columns. 2) Bind that to an entity using the designer and expose it over a WebAPI Odata endpoint 3) Using the Odata framework, construct a query that selects all 100 rows from the entity. Note, you have to **explicitly** select the rows. Allowing the default select (which returns all rows) or doing a ""Select=*"" will not reproduce the problem. EX: `http://localhost/odata/entity?$select=col1,col2,...col99,col100` 4) W3WP crashes with an unhandled exception. You can see this in the Application Log. ``` Faulting application name: w3wp.exe, version: 8.0.9200.16384, time stamp: 0x50108835 Faulting module name: clrjit.dll, version: 4.6.96.0, time stamp: 0x55b96549 Exception code: 0xc00000fd Fault offset: 0x00000000000778ac Faulting process id: 0x2f4c Faulting application start time: 0x01d19b20a1c244cf Faulting application path: c:\windows\system32\inetsrv\w3wp.exe Faulting module path: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clrjit.dll Report Id: 7678dc0b-071e-11e6-945c-000d3a900c63 Faulting package full name: Faulting package-relative application ID: ``` 5) Attach a debugger and make the request again. Make sure your IDE is set to stop on all exceptions and you will see this exception is caught. (The line is annotated in the Example code code blow). Dig into the error and you will see it being thrown from EntityFramework.dll. ``` System.StackOverflowException was unhandled HResult=-2147023895 Message=Exception of type 'System.StackOverflowException' was thrown. InnerException: ``` #### Notes - I did some testing, and as soon as we select more than 96 columns the stackoverflow is thrown. Select 96 or less and it works - Notice we are not using a strongly typed entity. As far as PushStreamContent is concerned, it is just an IQueryable. I think this is important because a few years ago [this non-public patch](https://support.microsoft.com/en-us/kb/2384016) was put put for something very similar. I know it isn't the same, but there are similarities. I assume this would have been included in subsequent versions though. > - If I change the endpoint to _not_ use the PushStreamContent and instead just return the data like you see in most applications (i.e. `return Request.CreateResponse(view );`) it actually works. This leads me to believe it has something to do with the enumeration over the IQueryable. _Edit: The above point is wrong. It will fail either way_ - I mention it in passing, but I want to call out that if the client does a `$select=*`, then everything works. Even if there are more than the 96 columns. I wonder if it has to do with the size of the expression tree being built? - I have traced the bug down to the System.Linq.Expressions.Compiler.LambdaCompiler specifically this: ``` private void EmitLambdaBody() { // The lambda body is the ""last"" expression of the lambda CompilationFlags tailCallFlag = _lambda.TailCall ? CompilationFlags.EmitAsTail : CompilationFlags.EmitAsNoTail; EmitLambdaBody(null, false, tailCallFlag); } ``` #### Example code _you can see here that we are not using the @Queryable annotation, but instead calling options.ApplyTo our self_ ``` public HttpResponseMessage GetEntity(ODataQueryOptions options) { //the IsPublic isn't important here. I am just showing the we do additional query filtering on top of what the client asks for IQueryable view = options.ApplyTo(DbContext.vwEntity.where(row => row.IsPublic)); return new ResponseStreamer(Request).StreamAsync(view); } ``` _ResponseStreamer takes the current HttpWebRequests, and flushes rows out to a `PushStreamContent` as we get read them from the database. This, in essence, allows us to send rows to the client as fast as we are able to get them from SQL_ ``` public HttpResponseMessage StreamAsync(IQueryable data) { HttpResponseMessage response = request.CreateResponse(); response.Content = new PushStreamContent( async (outputStream, httpContent, transportContext) => { try { using (TextWriter tw = new StreamWriter(outputStream)) { using (JsonWriter writer = new JsonTextWriter(tw)) { writer.WriteStartArray(); // The exception is throw while enumerating over ""data"" foreach (var item in data) { string json = JsonConvert.SerializeObject(item)+"",""+Environment.NewLine; writer.WriteRaw(json); await outputStream.FlushAsync(); } writer.WriteEndArray(); } } } catch (Exception ex) { var errorBuffer = Encoding.Default.GetBytes(""an error for the client to see""); outputStream.Write(errorBuffer, 0, errorBuffer.Length); outputStream.Flush(); } finally { outputStream.Close(); } }); return response; } ``` #### Stacktrace ``` [Managed to Native Transition] mscorlib.dll!System.Reflection.Emit.DynamicMethod.CreateDelegate(System.Type delegateType = {Name = Inspecting the state of an object in the debuggee of type System.Type is not supported in this context.

And if the .sln file specifies a certain configuration for your .csproj file and your .csproj file doesn't have this magic line, VS ""helpfully"" ""fixes"" your .sln to use a configuration that the .csproj appears to support (how does it know it picked a good one?

I was working on pushing down forward-only IL decoding out of IL -> IOperation prototype (but still in separate assembly from SRM for now) and found that BlobReader hides some things (kept internal) that are of general use. Given a BlobReader, I should be able to drop down to pointers/unsafe myself and I should also be able to skip around without resorting to copying a previous BlobReader instance at a previous position which has a bunch of fields (I think we can cut those down, but still, seek should be as cheap as possible). 8005 area-System.Net Add tests for HtmlDecode and HtmlEncode to WebUtility - Valid encoding - Invalid encoding - Unecessary encoding - No encoding needed - High BMP chars - Surrogate pairs - Chars in range 160-255 /cc @davidsh @stephentoub @jamesqo 8006 area-System.Net Add several HttpClient mini-stress tests Several outerloop tests that verify HttpClient doesn't completely fall over under some load: - Use one HttpClient instance to make many requests serially and in parallel - Use multiple HttpClient instances to make many requests serially and in parallel - Ensure that HttpResponseMessages can be GCd even if the associated response hasn't been fully drained.

For example, [here](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/IO/Stream.cs#L894) is the source code of `NullStream.FlushAsync` in CoreCLR, and [here](https://github.com/dotnet/corefx/blob/master/src/System.IO/src/System/IO/Stream.cs#L412) it is in CoreFX. Attempting to await the previous results in a `TaskCanceledException`, and the latter an `OperationCanceledException`. The fix would be to remove the `ThrowIfCancellationRequested` calls (along with all of the `pragmas`) and replace them with an `IsCancellationRequested` - `Task.FromCanceled` pattern. @stephentoub, do you know of any reason why the behaviors should differ? If not then I can submit a PR (along with tests) to fix this. 8013 area-System.Net SocketException improvements - Move all instantiation of InternalSocketException into SocketExceptionFactory. Rename InternalSocketException to ExtendedSocketException, and encapsulate it in SocketExceptionFactory to prevent a proliferation of dependencies on this type. - Add support for adding an EndPoint to the exception message in ExtendedSocketException (fixes #7873). - Remove the TODOs around #7853. I don't believe it's worth complicating the public contracts just in case someone does an exact type equality comparison on a SocketException.

Unfortunately, .NET has no such equivalent and developers are forced to roll their own hashes like [this](http://stackoverflow.com/a/263416/4077294): ``` cs public override int GetHashCode() { unchecked { int result = 17; result = result * 23 + field1.GetHashCode(); result = result * 23 + field2.GetHashCode(); return result; } } ``` [Sometimes](https://msdn.microsoft.com/en-us/library/system.object.gethashcode.aspx) people even resort to using `Tuple.Create(field1, field2, ...).GetHashCode()` for this, which is bad (obviously) since it allocates. ### Proposal - List of changes in current proposal (against last approved version https://github.com/dotnet/corefx/issues/8034#issuecomment-262331783): - `Empty` property added (as natural starting point analogous to `ImmutableArray`) - Argument names updated: `hash`->`hashCode`, `obj` -> `item` ```cs namespace System { public struct HashCode : IEquatable { public HashCode(); public static HashCode Empty { get; } public static HashCode Create(int hashCode); public static HashCode Create(T item); public static HashCode Create(T item, IEqualityComparer comparer); public HashCode Combine(int hashCode); public HashCode Combine(T item); public HashCode Combine(T item, IEqualityComparer comparer); public int Value { get; } public static implicit operator int(HashCode hashCode); public static bool operator ==(HashCode left, HashCode right); public static bool operator !=(HashCode left, HashCode right); public bool Equals(HashCode other); public override bool Equals(object obj); public override int GetHashCode(); public override string ToString(); } } ``` Usage: ```c# int hashCode1 = HashCode.Create(f1).Combine(f2).Value; int hashCode2 = hashes.Aggregate(HashCode.Empty, (seed, hash) => seed.Combine(hash)); var hashCode3 = HashCode.Empty; foreach (int hash in hashes) { hashCode3 = hashCode3.Combine(hash); } (int)hashCode3; ``` ### Notes Implementation should use algorithm in [`HashHelpers`](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Numerics/Hashing/HashHelpers.cs#L9). 8036 area-System.Linq Allow ListInitExpression to have zero initializers Akin to #1877 allowing zero case blocks in a `SwitchExpression` and #3043 allowing empty `BlockExpression`s, it seems reasonable to allow `ListInitExpression`s to have zero elements.

The downside of this is that it is using memory that won't be paged out and the max size is 64kb. Polling avoids this issue. ### Some downsides: - Doesn't scale well to very large directories e.g. an entire drive. - Generally considered to be less performant than the OS's watching APIs (though there are some factors that affect this like buffer size, watched directory size, and polling frequency). #### Bringing it to CoreFX There would be a few ways to bring the Polling FSW into CoreFX that we can consider: 1. Bring it in its own library System.IO.FileSystem.Watcher.Polling that is completely separate from the existing FSW 2. Put it into System.IO.FileSystem.Watcher but have it be its own separate class 3. Merge the implementation into the existing FSW and provide a bool constructor overload (e.g. `bool poll = false`) that allows specification of which implementation to use 4. Merge the implementation into the existing FSW and try to programatically determine which implementation to use. We could base our decision on the initial number of entries in the watched directory, for example. 5. Merge the implementation into the existing FSW and use both in unison. Use the OS's API's but also poll every now and then to catch things that the OS's FSW may have missed. 6. Replace our existing implementation with a polling implementation ### Examples of demand for a polling FSW: - https://github.com/dotnet/corefx/issues/7576 - http://stackoverflow.com/questions/239988/filesystemwatcher-vs-polling-to-watch-for-file-changes/240008#240008 - http://stackoverflow.com/questions/3612311/monitoring-a-directory-for-new-file-creation-without-filesystemwatcher/3612432#3612432 @KrzysztofCwalina @stephentoub @sokket @joshfree @chcosta 8061 area-System.Net Timeout_SetTo60AndGetResponseFromServerWhichTakes40_Success failed on Windows The handle is invalid http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/outerloop_win10_debug/12/consoleText ``` System.Net.Http.Functional.Tests.HttpClientTest.Timeout_SetTo60AndGetResponseFromServerWhichTakes40_Success [FAIL] System.Net.Http.HttpRequestException : An error occurred while sending the request. ---- System.Net.Http.WinHttpException : The handle is invalid Stack Trace: at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() d:\j\workspace\outerloop_win---097a300f\src\System.Net.Http\src\System\Net\Http\HttpClient.cs(392,0): at System.Net.Http.HttpClient.d__58.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() d:\j\workspace\outerloop_win---097a300f\src\System.Net.Http\tests\FunctionalTests\HttpClientTest.cs(389,0): at System.Net.Http.Functional.Tests.HttpClientTest.Timeout_SetTo60AndGetResponseFromServerWhichTakes40_Success() ----- Inner Stack Trace ----- d:\j\workspace\outerloop_win---097a300f\src\System.Net.Http.WinHttpHandler\src\System\Net\Http\WinHttpHandler.cs(1360,0): at System.Net.Http.WinHttpHandler.InternalReceiveResponseHeadersAsync(WinHttpRequestState state) d:\j\workspace\outerloop_win---097a300f\src\System.Net.Http.WinHttpHandler\src\System\Net\Http\WinHttpHandler.cs(850,0): at System.Net.Http.WinHttpHandler.d__102.MoveNext() ``` 8063 area-System.Net Fixed typo in GetHostAddressesAsync test for Dns class Fixed typo in GetHostAddressesAsync() test. 8064 area-Serialization System.Xml.XmlSerializer Perf tests failing @khdang when I run `msbuild /t:BuildAndTest src\System.Xml.XmlSerializer\tests\System.Xml.XmlSerializer.Tests.csproj /p:Performance=true` there seem to be some exceptions being thrown `System.Xml.XmlSerializer.Tests.Performance.XsPerformanceTest.XsSerializationTest(numberOfRuns: 1000, testType: Dictionary, testSize: 128) [FAIL] System.NotSupportedException : The type System.Collections.Generic.Dictionary`2[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[System.String, mscorlib, Version=4.0.0.0, Culture=neutr al, PublicKeyToken=7cec85d7bea7798e]] is not supported because it implements IDictionary.` Could you take a look and fix this 8065 area-System.Collections Fix ListDictionary.CopyTo throwing IndexOutOfRangeException - Now works as expected according to MSDN docs - Found in #7997, and caused inconsistencies in HybridDictionary behaviour at different lengths I got the impression that we should not throw an exception if count == 0, let me know if this is incorrect. /cc @ianhays 8066 area-System.Net OSX System.Net.NetworkInformation.Functional.Tests timeout in CI "http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/osx_debug_prtest/263/console > 08:53:21 Discovering: System.Net.NetworkInformation.Functional.Tests > 08:53:21 Discovered: System.Net.NetworkInformation.Functional.Tests > 08:53:21 Starting: System.Net.NetworkInformation.Functional.Tests > 08:53:21 System.Xml.XDocument.xNodeBuilder.Tests -> /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_debug_prtest/bin/AnyOS.AnyCPU.Debug/System.Xml.XDocument.xNodeBuilder.Tests/System.Xml.XDocument.xNodeBuilder.Tests.dll > 10:22:33 > Build timed out (after 120 minutes).

The following works: ``` C# Expression.Lambda( Expression.Constant(3L), Enumerable.Range(0, 20).Select(_ => Expression.Variable(typeof(int).MakePointerType())) ); ``` However, the following does not: ``` C# Expression.Lambda( Expression.Constant(3L), Enumerable.Range(0, 2).Select(_ => Expression.Variable(typeof(int).MakePointerType())) ); ``` The difference being whether the arity is higher than the highest-arity `Func<>` delegate or not. Neither are likely to be useful, as pointer types hit snags elsewhere, but if the former is allowed, then so should be the latter. 8077 area-System.Text How do i get an spesified encoding like this.

" 8081 area-System.Linq Expressions can be typed as open generic types The likes of `Expression.Default(typeof(List<>))`, `Expression.Constant(null, typeof(Dictionary<,>))` and some other expressions (though often other rules will get in the way) are allowed. Since these represent a value of an open generic type, they aren't really meaningful. They can have a value of null which can be used as long as it is converted to `object` and both compilation types accept `Expression.Lambda>(Expression.Default(typeof(List<>)))` as an expression that can be compiled into a delegate that returns null. While they can be pressed into service, it seems more appropriate to prohibit them. Factory methods that have at least one overload that takes `Type` arguments directly. Will check these off when they're either found to already prohibit such types, or fixed to do so (PRs just adding tests of already-correct behaviour marked immediately, PRs fixing behaviour upon acceptance): - [x] `Block` (entailed in check that type is reference-assignable from type of last child expression). - [x] `Break` - [x] `Call` #17333 - [x] `Catch` - [x] `Condition` - [x] `Constant` - [x] `Continue` - [x] `Convert` - [x] `ConvertChecked` - [x] `Default` - [x] `Dynamic` (Entailed in check that arguments match delegate method). - [x] `Field` #16231 - [x] `GetActionType` (Exception: Has practical use here) - [x] `GetDelegateType` (Exception: Has practical use here) - [x] `GetFuncType` (Exception: Has practical use here) - [x] `Goto` - [x] `Label` #16140 - [x] `Lambda` #16233 - [x] `MakeCatchBlock` - [x] `MakeDynamic` (Entailed in check that arguments match delegate method). - [x] `MakeGoto` - [x] `MakeTry` (entailed by check that type is void or that body and catch types are reference-assignable) - [x] `MakeUnary` Waiting on #16141 - [x] `New` - [x] `NewArrayBounds` - [x] `NewArrayInit` - [x] `Parameter` (byref types allowed) - [x] `Property` #16231 - [x] `Rethrow` #16141 - [x] `Return` - [x] `Switch` (Entailed by check that type is void or default and case types are reference-assignable) - [x] `Throw` #16141 - [x] `TryGetActionType` (Exception: Has practical use here) - [x] `TryGetFuncType` (Exception: Has practical use here) - [x] `TypeAs` - [x] `TypeEqual` #16150 (pointer types allowed; always results in `false`) - [x] `TypeIs` #16150 (pointer types allowed; always results in `false`) - [x] `Unbox` #16186 - [x] `Variable` Also the following have overrides that take `MemberInfo`, which could be generic and/or be related to an open generic type.

Today, if you make a ResponseHeadersRead request on an HttpClient and then drop it without disposing it, the associated state will end up being leaked into the HttpClient until either the HttpClient is disposed or until the request times out, which by default is 60 seconds but could have been extended to never. This change enables such requests to be finalized. See the detailed comment in CurlHandler.cs for a description of the approach taken.

"Considering the likes of: ``` C# private class ReducesFromStrangeNodeType : Expression { public override Type Type => typeof(int); public override ExpressionType NodeType => (ExpressionType)(-1); public override bool CanReduce => true; public override Expression Reduce() => Constant(3); } ``` Attempting to compile will throw a reasonable `PlatformNotSupportedException` on the interpreter, but an unreachable error (assertion failure in debug, IOE with the text ""Code supposed to be unreachable"" in release) on the interpreter. At the very least the code clearly isn't unreachable when it's just been reached. Having the compiler match the interpreter would be reasonable enough, but having both call `ReduceAndCheck()` and acting on the results is probably better still; in the worse case there's a better exception than saying the code isn't reachable, and if the node is reducible, we can compile it.

Here is a real example of use why build time OS Information without the real runtime is not a good idea. See discussions here: - https://github.com/dotnet/corefx/issues/3032 - https://github.com/dotnet/corefx/issues/6105 - https://github.com/dotnet/corefx/issues/1017 I code for a managed NoSQL database and for us performance is a must; therefore in some cases we have to do some platform specific stuff like calling PrefetchVirtualMemory. The problem is that the function is not supported on any OS, it is only supported in Windows 8+. While this may look like an isolated example, not even in windows (which is very stable) the runtime is changing and underlying APIs are not set in stone. Knowing that, think about newer platforms like Android where versions numbers would mean something is viable or not. Not having a cross-platform way to query the runtime is a no-no for performance and support OS that are not mature enough to absolutely not require having specific dedicated codepath depending on the runtime.

" 8114 area-System.Text System.Text.Encoding and System.Text.Encoding.Extensions test duplication Currently, the System.Text.Encoding and System.Text.Encoding.Extensions test projects test the same things for the same classes - I.e. ASCIIEncoding, UT7Encoding, UTF32Encoding, UTD8Encoding and UnicodeEncoding. For Latin1Encoding, System.Text.Encoding.Extensions is the only one testing this class This means that there is lots of duplication between the test projects. Ideally, this should be fixed. There are some solutions: - Remove/combine the tests in System.Text.Encoding.Extensions to the new more modern System.Text.Encoding.Tests - Extract the current tests in System.Text.Encoding.Tests and System.Text.Encoding.Extensions to src/common/tests and reference the files in both projects - keep as is, and duplicate tests (not an ideal solution IMO) My preferred solution is to migrate the existing non-duplicated tests to System.Text.Encoding.Tests as that project is more modern. In terms of coverage loss, there wouldn't really be any, as the code is in mscorlib anyway. In fact, this could consolidate coverage even more by having he tests in one place. @tarekgh let me know what approach you think is the best and I'll work on it 8115 area-System.Net Refactor SafeFreeCredentials class Tracking issue to fix the following code smells [``SafeFreeCredentials`](https://github.com/dotnet/corefx/blob/master/src/Common/src/Interop/Unix/libssl/SecuritySafeHandles.cs#L62) class: ~~\* As pointed out in [the PR comments of #6469](https://github.com/dotnet/corefx/pull/6469#discussion_r56659315), this class needs to be split up into two separate classes~~ (via #8452) - Rework PAL to remove non- SafeHandle SafeHandles.

Instead of using a `ConditionalFlag`, each test [checks if the installation is successful or not](https://github.com/dotnet/corefx/blob/master/src/System.Net.Security/tests/FunctionalTests/NegotiateStreamTestForUnix.cs#L155) and bails out if it wasn't. This means that we cannot rely on the output of xunit to know if the test was successful or if it was skipped. This was written this way due to following orthogonal constraints: 1. Unlike other tests, the NegotiateStreamTests were expected to download and install the prereqs (This constraint is related to the infra team). 2. When the tests are run on a dev machine, the installation should be done only if the developer chooses to do so. 3. If the developer does not choose to download, install and configure KDC (presumably because he/she is not testing negotiatestream) the outerloop should not fail. 4. If the tests install anything, we need to uninstall them as well. In order to achieve 1 and 4, we need to use the XUnit's disposable fixture mechanism. But XUnit can only guarantee that the fixture instance is created before the any of the test is run. There are no documented relative ordering of - fixture instance creation - filtering of test cases Thus making it really tricky to achieve all the four requirements. 8119 area-System.Linq TryGetActionType and TryGetFuncType throw on some failures instead of returning false/null. If there are too many types, too few, or if one of the types is `ByRef` then these return false (with `null` to the `out` parameter) as expected. However, if the type list is null, contains null, contains a pointer type, or contains `typeof(void)`, they throw an exception, contrary to the `TryXXX` semantics. Throwing on null or containing null is perhaps defensible, but probably still incorrect. Throwing on pointer types and void less so. 8120 area-System.Linq Are types VBCallSiteDelegate0…7 missing? There's code in src/Common/src/System/Linq/Expressions/Compiler/DelegateHelpers.Generated.cs defining and using public types `VBCallSiteDelegate0` through `VBCallSiteDelegate7`. Because these are wrapped in `#if !FEATURE_COMPILE` they aren't active. Since however the compiler and interpreter used to be mutually exclusive, `!FEATURE_COMPILER` used to entail `FEATURE_INTERPRET` perhaps this should in fact be wrapped with `#if FEATURE_INTERPRET` and hence lit up? Has a type that was public in some contexts been removed due to this? CC @VSadov @bartdesmet 8121 area-System.Linq Expression.GetDelegateType works with pointer types for high arity but not for low. The following works: ``` C# Expression.GetDelegateType(Enumerable.Repeat(typeof(int).MakePointerType(), 18).ToArray()) ``` But the following throws `ArgumentException`: ``` C# Expression.GetDelegateType(Enumerable.Repeat(typeof(int).MakePointerType(), 17).ToArray()) ``` This is similar to (indeed, a variant of) #8074, but differs as while there the usefulness of lambda expressions that take pointer arguments is questionable, here the delegate could be used in a variety of ways that don't meet the same issues, so there's more value in making both work, rather than in making both throw. 8123 area-System.ComponentModel Allow DisplayAttribute on Class declarations Hello, I'd like you to consider allowing `DisplayAttribute` on class declarations. Forgive me if this is a duplicate, I haven't found anything related. Some use cases for it: - Auto-generate form captions - Auto-generate report captions - Use this information to extend nested property captions (like `Person.Details.Address` could get a label as `Personal info / Address`) - Auto-generate documentation (consuming `Description` and `Order` for example) - etc. 8124 area-System.Security Make System.Security.Cryptography.Native.dylib reference libcrypto/libssl via rpath The brew installed openssl has a library id of /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib, which doesn't seem to interact well with the macports installed version.

I don't know why this particular test is so much more susceptible to that, but I've changed the test to use a local loopback server rather than an external site. - The SendAsync_ReadFromSlowStreamingServer_PartialDataReturned test was relying on timings from the server that might not always be correct, and due to internal differences between curl and WinHttp were very frequently wrong on Unix such that the test was disabled there. I reimplemented it with a local loopback server, too. - I've added another mini-stress test, with posts instead of gets.

We either need a story or decide we don't have a story. "This came up as an underlying issue in Issue #6857. Opening this as a Future issue to track. What's a developer to do if you need to compare two Reflection objects such as ParameterInfo for ""semantic equality""? On .NET Native, we actually did override Equals/GetHashCode on these objects and they perform semantic equality. However, .NET Native uses a completely different implementation of Reflection. On CoreClr, Reflection objects inherit the Object Equals() method, so those checks are just reference equality checks. They don't check semantic equality, but they often fool people into thinking they do because the CLR often caches Reflection objects for reuse. We probably don't want to make the caching 100% (unnecessary memory usage) but overriding Equals/GetHashCode may also have its costs (surface area compat? What about user-extended Reflection types if we ever support that?)

So far, we identified a couple of enabler features that we do need to add to the core to make such out-of-band serializers possible: 1. FormatterServices.GetUninitializedObject 2. Exception.set_StackTrace This issue/request is to add these two asap. They are absolutely blocking and required. We might need more as we work with partners and community on enabling their scenarios.

This forces using exceptions for control flow: ``` try { task.Wait(); } catch (AggEx) { } //Do nothing. ``` This is ugly and _very_ slow. Exceptions seem to cost ~0.1ms of CPU time to process. So if you are writing a port scanner using async IO you will find that you cannot scan more that 10k ports per second because the CPU is pegged from exception processing(!). Also, I don't know if exceptions scale across CPUs. I know that `ExceptionDispatchInfo` uses a global lock internally. So at least some of the processing does not scale at all. It might not be too common to have many faulted tasks. But it is more likely to rely on a greater number of cancelled tasks. I know of two workarounds: ``` Task.WhenAny(task); //params overload task.CW(() => { }, ExecuteSynchronously).Wait(); ``` Both allocate, add overhead and both make it unclear what you want to achieve. Please add a simpler and faster way to wait for a task to complete regardless of the terminal state it ends up in. The same problem exists with `await`. There is no direct way to wait for completion without throwing. Maybe `ConfigureAwait` can be extended with an `AwaitOptions` enum that has the values `IgnoreContext, NoThrow`. 8144 area-System.Net System.Net.Requests: Specify the capacity when creating the PrefixList Minor improvement: Specify the capacity when creating `WebRequest`'s `PrefixList` and reuse the same `HttpRequestCreator` instance for both http and https. As part of that, I added an explicit dependency on `System.Diagnostics.Debug`, so I could add a `Debug.Assert` (it was already being pulled in by other dependencies). While I was at it, I removed the dependency on `System.Diagnostics.Contracts` because it was only being used in one place and code contracts are not being maintained in .NET Core. I also made a few fields readonly, along with fixing the naming/capitalization of a couple parameters in the same class. cc: @davidsh, @stephentoub 8146 area-System.IO System.IO.Compression: Create ExtractToDirectory overload that accepts 'overwrite' boolean "Currently `ExtractToDirectory` is only useful if the target directory is virginal (eg clean or contains files which are not in the zip being extracted).

I would like to ask the developers to consider writing a new overload for the `ExtractToDirectory` method that includes an 'overwrite existing files' parameter. Many thanks. " 8150 area-System.Net Fix HttpRequestMessage.Version tests The current tests validating HTTP request message version were depending on a server behavior that is not guaranteed. In particular, HTTP RFC 7230 states that servers are NOT required to respond back with the same minor version if they support a higher minor version. In fact, the RFC states that servers SHOULD send back the highest minor version they support. So, testing the response version to see if the client sent a particular request version only works for some servers. In particular the 'Http2Servers' used in these tests seemed to echo the minor version of the request. However, depending on network configuration, intermediate proxies can change the HTTP version that ends up getting sent to the destination server. And as a result, we can have unpredictable behavior in these tests. To fix this, the tests were switched to use a loopback server that has deterministic behavior. 8153 area-System.Net Disable hanging OSX NetworkInformation test Based on my very basic investigation, it looks like the thread running CFRunLoopRun is not being terminated properly, which should happen after the only listener unsubscribes on the third line of the test case.

But the process of doing that goes something like this: - Figure out there is no way to specify just `leaveOpen`. - From the documentation of `StreamWriter(Stream stream)`, figure out that the default encoding is UTF-8. (Though it doesn't mention it's actually UTF-8 _without BOM_.) - Either make a guess about what a good buffer size is, or look at the source code of `StreamWriter`. - Finally write `new StreamWriter(stream, Encoding.UTF8, 1024, true)`. I don't think that's acceptable, so I'm proposing to make `new StreamWriter(stream, leaveOpen: true)` work. I can see few options on how to do this: 1. Assuming optional arguments are okay (they probably aren't, see dotnet/corefx#470), make use of them by changing the full overload to: ``` c# public StreamWriter( Stream stream, Encoding encoding = null, int bufferSize = -1, bool leaveOpen = false) ``` This would require relaxing `encoding` and `bufferSize` to accept `null` and `-1`, respectively, but I think that's okay. I think this is the most convenient option, since it allows one to easily specify any combination of options. 2. Add a new constructor overload: ``` c# public StreamWriter(Stream stream, bool leaveOpen) ``` Adding some other overloads might make sense too. 3. Don't add anything, just relax `encoding` and `bufferSize` as in option 1. I think this is the most conservative option, but also least convenient, since it would require writing `new StreamWriter(stream, null, -1, true)`. 8175 area-System.Net Clean up ResponseStreamTest Used the MD5 hash verification when verifying correct response body dowload.

We expect the writes to all be asynchronous via WriteAsync. However, it's possible for an override of CopyToAsync to use Write, and if it does, and if we just delegated from Write(...) to WriteAsync(...).GetAwaiter().GetResult(), we would likely deadlock, as the CopyToAsync call is invoked from the single thread responsible for processing libcurl interactions, including supplying the reader that would unblock the writer. To handle this, we have two options: schedule the CopyToAsync to be invoked asynchronously just in case it does a synchronous write, or implement the write to buffer the data. The former is what was done in https://github.com/dotnet/corefx/pull/4095. It adds some cost to the expected / common case, but more importantly and worse it can also lead to concurrency problems and spurious exceptions, as for example if the request is faulted/canceled between the time that a task to invoke CopyToAsync is scheduled and the time that it actually executes, we could be invoking CopyToAsync on a disposed HttpContent; worse, we could end up invoking CopyToAsync while it's being disposed, which could lead to arbitrary state corruption, and which means we can't guard against this with checks to see if the task has already completed. The only way to fully guard against that is via a lock, but such a lock would itself lead to deadlocks, as the reader that would unblock the writer would have to take the same lock. In comparison, buffering has the downside of taking up more and arbitrary amounts of memory to store all of the input. But, we expect synchronous Writes to be rare, and code shouldn't be doing it anyway; if it does, the fix should really be to switch to asynchronous writes. This commit changes from the first approach to the second, using buffering in synchronous Write calls in order to ensure correctness and to optimize for the expected case. @mconnew, @roncain, this all originally started from https://github.com/dotnet/corefx/issues/4077. Is WCF still doing such synchronous writes as part of HttpContent.CopyToAsync? If so, is this change going to cause a problem for that? We're between a rock and a hard place given the design of HttpClient.

While it might not be feasible to change the default to ephemeral, we should add the option to allow better guarantees against key-leak. (PKCS12_NO_PERSIST_KEY, Vista+) ## Rationale Currently .NET supports loading a PFX in two different key-persistence modes. The default mode, which I call perphemeral (a portmanteau of persistent and ephemeral), is to let the key file be created on disk, and then delete that file when the certificate is disposed. Alternatively, the PFX can be loaded with X509KeyStorageFlags.PersistKeySet, and then the key files will not be deleted upon certificate disposal. Both current modes have some pros and some cons: ### Persisted - Pro: You can add it to a persisted X509Store meaningfully. - Pro: new X509Certificate2(cert.Handle) has no surprises - Con: If you open a PFX persisted to add it to an X509Store, and detect the duplicate, you still have emitted the key. (Cleanup is possible, but hard to do correctly) - Con: If you meant to use the key ephemerally this leaks a file on disk every time you use it. ### Perphemeral (default) - Pro: If your application terminates normally, no net key material was leaked to disk. - Con: If you add a perphemeral cert to an X509Store the key file is still deleted, so while it is temporarily a public/private pair in the store it finishes as a public-only import. - Con: new X509Certificate2(cert.Handle) makes the cleanup hard to assess from a user perspective (it's stable, but hard to describe). - Con: If your application does not terminate normally (or it was held outside of the scope of finalization), the keyfile leaks as if you had opened it with PersistKeySet. - Con: Under parallel loads of the same PFX there's a if-available-use race condition (out of our reach) where two different objects were given the same backing keyfile; disposing one copy eliminates the keyfile of the other. When seeking ephemeral behavior (load from a PFX, do some signing/decrypting, dispose) it seems significantly better to just load it ephemerally. ### Ephemeral (new proposal) - Pro: No key material is ever written to disk (modulo the pagefile) so it can't create a persisted file under any circumstance. - Pro: Immune to parallel load race conditions - Pro: new X509Certificate2(cert.Handle) behaves just fine. - Con: Adding the cert to an X509Store may behave as adding the public key only. - Con: Existing interop code expecting to load the key name structure will fail. ## Proposed API: ``` diff public enum X509KeyStorageFlags { DefaultKeySet = 0, + EphemeralKeys = 32, Exportable = 4, MachineKeySet = 2, PersistKeySet = 16, UserKeySet = 1, UserProtected = 8, } ``` Opening an X509Certificate2 (or Importing into a collection) with both PersistKeySet and EphemeralKeySet defined will be an error. On Windows EphemeralKeySet will also force loading into CNG. On Unix this flag has no effect. Since the key handle is now actually owned by the native object, we need to track that dependency like an interior pointer. To that end, new public members have to be added into the CNG contract: ``` diff public abstract partial class SafeNCryptHandle : System.Runtime.InteropServices.SafeHandle { protected SafeNCryptHandle() : base (default(System.IntPtr), default(bool)) { } + protected SafeNCryptHandle(System.IntPtr handle, System.Runtime.InteropServices.SafeHandle parentHandle) : base (default(System.IntPtr), default(bool)) { } public override bool IsInvalid { get { return default(bool); } } protected override bool ReleaseHandle() { return default(bool); } protected abstract bool ReleaseNativeHandle(); } public sealed partial class SafeNCryptKeyHandle : Microsoft.Win32.SafeHandles.SafeNCryptHandle { public SafeNCryptKeyHandle() { } + public SafeNCryptKeyHandle(System.IntPtr handle, System.Runtime.InteropServices.SafeHandle parentHandle) : base (default(System.IntPtr), default(System.Runtime.InteropServices.SafeHandle)) { } protected override bool ReleaseNativeHandle() { return default(bool); } } ``` The parentHandle constructors of these SafeHandles will require that parentHandle be - Not null (ArgumentNullException) - Not IsClosed (ArgumentException) - Not IsInvalid (ArgumentException) otherwise, it will AddRef in the constructor and Release in ReleaseHandle. 8187 area-System.Security Add support for getting a private key handle with no UI prompting "Equivalently ""pass CRYPT_SILENT when opening the key handle"". While some apps may want to use that key and get the PIN/unprotect prompt, other contexts are headless and would rather opening the key just fail. We should add an overload to Get[Algorithm]PrivateKey which lets the caller suppress UI. " 8188 area-System.Data Are Query Notifications on the roadmap?

This is to track the Channel Binding support for NegotiateStream . 8220 area-System.Reflection Attribute.GetCustomAttributes does not resepct 'inherit' flag for non-RuntimeTypes. "The method `GetCustomAttributes` on `PropertyInfo` and `EventInfo` ignores the `inherit` parameter, which is mentioned in the documentation. Instead one is supposed to use the `Attribute.GetCustomAttributes` method to get attributes in the inheritance chain. The problem is that this method only walks the inheritance chain if the type of the `PropertyInfo` (or rather the `MethodInfo` returned from `GetAccessors()` in the case of a property) is an instance of `RuntimePropertyInfo` (or `RuntimeMethodInfo`). This means that for any custom implementation of a `MemberInfo`, such as those provided from `CustomReflectionContext`, there is no way to get the attributes in the inheritance chain in a transparent way, regardless of the implementation of the `MemberInfo` in question. Suggest that the implementation of `Attribute.GetCustomAttributes()` is changed so that it works regardless of the underlying implementation of the `MemberInfo` provided. A sample program illustrating the issue: ```c# [AttributeUsage(AttributeTargets.All, Inherited = true)] public sealed class TestAttribute : Attribute { } class A { [Test] public virtual object MyProp { get; set; } } class B : A { public override object MyProp { get; set; } } class MyReflectionContext : CustomReflectionContext { } class Program { static void Main(string[] args) { PropertyInfo propertyInfo = typeof(B).GetProperty(""MyProp""); var attrs1 = propertyInfo.GetCustomAttributes(true); var attrs2 = Attribute.GetCustomAttributes(propertyInfo, true); MyReflectionContext ctx = new MyReflectionContext(); propertyInfo = ctx.MapType(typeof(B).GetTypeInfo()).GetProperty(""MyProp""); var attrs3 = propertyInfo.GetCustomAttributes(true); var attrs4 = Attribute.GetCustomAttributes(propertyInfo, true); Console.WriteLine(attrs1.Length); // Returns 0 - As expected Console.WriteLine(attrs2.Length); // Returns 1 - As expected Console.WriteLine(attrs3.Length); // Returns 0 - As epected Console.WriteLine(attrs4.Length); // Returns 0 - We want 1 here! } } ``` " 8221 area-System.Net Implement server-side of NegotiateStream on Unix We currently only support the client side. 8223 area-System.Diagnostics Can we make EventCounter work in NetStandard 1.3?

There are a few top-level issues at the moment, immediately apparent by the current install instructions: ![image](https://cloud.githubusercontent.com/assets/115199/14971129/198149e8-1095-11e6-913f-3d58e3e6011a.png) 1. The current instructions to install .NET on Ubuntu are second-rate. The big issue here is that you are requiring additional steps when they could be avoided. If you examine Chrome and other debian packages, they are able to provide a PPA configuration without making you drop to the command line. You can consider this on par with an MSI installer: ![image](https://cloud.githubusercontent.com/assets/115199/14971157/597c511e-1095-11e6-819f-f40a604cf269.png) This entry, as viewed in the ""Software Sources"" app in Ubuntu did not require me to do anything except add the `.deb` found [here](https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb). It's also worth noting that using a PPA also avoids the need to make people do things with keys. 2. Only supporting 14.04. We're coming up to a month with 16.04. If the current build system cannot even support getting 14.10, 15.04 and 15.10 over the last 2 years, something has been seriously overlooked. At the very least, this is a problem you shouldn't be carrying into a 1.0 release. 3. ""Feeds"". Really, you can just package all the versions you want in a single feed and have a metapackage that points to the most current version. As you can see, there are a few things that can be done to reduce the number of touchpoints for an Ubuntu developer as well as increasing the likelihood that they can run this wonderful new platform with confidence.

An example is the link-local address provided by running `ifconfig`. 2. Run `curl` to verify the server is working. 2a. On Mac, I needed to wrap the IPv6 address with brackets, and escape the `%` as `%25`. For example: `curl http://[fe80::blah%25en0]:1234/`. 2b. On Linux, I needed to _not_ wrap with brackets, and _not_ escape the `%`. For example: `curl http://fe80::blah%eth0:1234/`. 3. Call `new HttpClient().GetAsync()` using the same URL you passed to curl. **Expected** HttpClient works the same as curl itself. **Actual** HttpClient fails with an error like `System.Net.Http.CurlException: Couldn't connect to server` or `System.UriFormatException: Invalid URI`. **Notes** I tested many combinations of with/without brackets and with/without `%` encoded as `%25`, but none of them worked.

area-System.IO Make win8 ARM clrcompression pkg win7-arm is not a valid RID. This commit removes that package and replaces it with an equivalent win8-arm package. resolves #7436 @weshaggard @ericstj 8358 area-System.IO Expose Stream.Begin/EndRead/Write in System.IO contract We really want devs to use Stream.Read/WriteAsync, but not having these Begin/End methods exposed breaks portability scenarios, e.g. where a stream in the full framework wraps another stream (e.g. SslStream) and the wrapper's async implementation wraps the Begin/End methods on the underlying Stream. Without these Begin/End members in the contract, it's impossible for a portable Stream implementation to plug in to that wrapper correctly. The core work here (for RTM) is to: - Expose the Begin/EndRead/Write virtual methods in the contract - Fix all of our Stream implementations in corefx to override these. In some cases, the methods already exist and we just need to change them from internal methods to public overrides. In other cases, we need to implement them and can do so easily on top of the Read/WriteAsync implementations. After that, we can optionally consider: - Changing the base Stream.Begin/EndRead/Write implementation to check if ReadAsync/WriteAsync are overridden, and if they are, delegating to those instead of queueing a work item that invokes the synchronous Read/Write. There are potential issues here, though, e.g. if a Stream overrides ReadAsync/WriteAsync to delegate to Begin/End which it doesn't override, at which point they'll end up in an infinite redirection loop. There may be ways to mitigate that. If we added that, we need a similar change (under a quirk) in the full framework. cc: @weshaggard, @terrajobst, @KrzysztofCwalina, @davidfowl, @benaadams 8359 area-System.ComponentModel Use generic collections in System.ComponentModel.TypeConverter implementation instead of non-generic 8360 area-System.Net IPAddress.ToString behavior difference: IPv6-mapped addresses format as regular IPv6 addresses From http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/ubuntu14.04_debug_prtest/823/testReport/junit/System.PrivateUri.Tests/UriIpHostTest/UriIPv6Host_EmbeddedIPv4_Success/ http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/ubuntu14.04_debug_prtest/823/ ``` MESSAGE: Assert.Equal() Failure ↓ (pos 10) Expected: [::ffff:0:c0a8:1] Actual: [::ffff:0:192.168.0.1] ↑ (pos 10) +++++++++++++++++++ STACK TRACE: at System.PrivateUri.Tests.UriIpHostTest.ParseIPv6Address(String ipv6String) at System.PrivateUri.Tests.UriIpHostTest.UriIPv6Host_EmbeddedIPv4_Success() ``` 8361 area-System.Net IPAddress.Parse behavior difference: failure to reject many bad IP address strings.

The instructions right now say: https://github.com/dotnet/corefx/blob/master/Documentation/building/windows-instructions.md “Visual Studio 2015 is required.” However, that is not sufficient using the default settings of Visual Studio 2015 install. The default settings will only install MsBuild 14.0. But the CoreFx CSPROJ and other scripts seem to want MsBuild 12.0 (you will see warning messages when doing “build” from the CoreFx root directory). In addition, it ends up using the C# 5 compiler: ![image](https://cloud.githubusercontent.com/assets/7684835/15089388/f19df56e-13b6-11e6-8b32-1ca1c936e675.png) This will cause compilation errors in System.Net.Http/src for example due to C# 6 features being used in the source files. The fix is to install these additional things from Visual Studio 2015. This will install MsBuild 12.0 tools. ![image](https://cloud.githubusercontent.com/assets/7684835/15089391/f85c2a2e-13b6-11e6-89b7-bb5cd0faf2fb.png) Which then results in the C# 6 compiler being used: ![image](https://cloud.githubusercontent.com/assets/7684835/15089394/ff56d630-13b6-11e6-9f7a-43d438f5ca89.png) Why does our build system require both MsBuild 12.0 and MsBuild 14.0 tools? 8371 area-System.Net Dns.GetHostAddressesAsync is blocking a ThreadPool thread The implementation of Dns.GetHostAddressesAsync is just a wrapper around the blocking implementation and is queued on the ThreadPool. https://github.com/dotnet/corefx/blob/1baa9ad06a466a5d6399e1e0a7a7a02564ab51b0/src/System.Net.NameResolution/src/System/Net/DNS.cs#L274 This can lead to a ThreadPool starvation when there are many concurrent calls of GetHostAddressAsync in an environment where the DNS is slow. The code in .Net 4.6 is slightly different but suffers from the same issue: http://referencesource.microsoft.com/#System/net/System/Net/DNS.cs,744 Windows and Linux both provides real asynchronous calls to resolve a DNS. The asynchronous implementation could use these. 8372 area-System.Security Add System.Security.SecureString to corefx We'd previously removed it due to not believing in the type, but it's used by enough apps that it's important to provide simply to aid in porting. This reverts the previous removal, and then does a bunch of work to fix it up to build and run again successfully. cc: @bartonjs, @weshaggard, @ellismg 8373 area-System.Net Add InvalidCredentialException to System.Net.Security contract It looks like this exception type was inadvertently left out of the contract file. It's a public type in the implementation and it's thrown in several places. cc: @davidsh, @cipop 8376 area-System.IO Reduce the minimum buffer size required by the StreamWriter class `StreamWriter` forces its `bufferSize` constructor parameter to be at least `128`. There is no workaround. This seems unnecessarily limiting. `bufferSize = 128` actually consumes about `256+(128*3)` bytes of memory with UTF8 (I checked this using the debugger). This is a significant amount of memory per instance. If the user really wants a smaller size, maybe knowing something about the data distribution, the user-specified value should take effect. For example, I might know that I will be writing only a few dozen bytes when serializing a cookie or an HTTP header. Simply lowering this minimum value would be a compatibility concern. So I propose this: The user-specified `bufferSize` value should be used with a minimum of `1`. Each time the buffer is actually exhausted, grow the internal buffers by doubling them each time until a size of `128` is reached. This way the user can specify a smaller buffer size if they know that not much data will be coming. But if a small size was mistakenly specified `StreamWriter` will quickly adapt to a bigger, more efficient buffer. This mitigates the compatibility concern. An alternative scheme would be to always start with a size of `16` and double until `max(bufferSize, 128)` is reached. That way the user-provided value is taken as a maximum instead of a precise value. I'm not convinced this scheme should be implemented. Just mentioning it. 8377 area-System.Net Add SSL support to LoopbackServer in HTTP tests We currently make a lot of calls off-box in our unit tests. By adding SSL support to the loopback server, we should be able to convert many more tests to avoid needing to actually hit the network. This adds such basic support, and converts a few tests to use it. Per previous PR feedback, I also moved the client-related code out of the loopback server, moving it to the call sites. Those call sites will be more easily reviewed with whitespace-diffing disabled, as the majority of the changes are indentation due to adding using blocks. Also, since I was moving the certificate configuration code to a central location, I fixed an issue related to cleanup.

This commit adds back the virtual methods in the contract and provides an implementation for Stream in corert (coreclr already has implementations in mscorlib). It also provides overrides on the streams defined in System.IO.dll. Once a new package is published with this updated contract, I'll add overrides to the rest of our stream implementations in corefx as well as tests. cc: @ianhays, @weshaggard, @danmosemsft, @KrzysztofCwalina, @jkotas 8379 area-System.Security Evaluate the impact of changing to CryptProtectData in SecureString https://github.com/dotnet/corefx/pull/8372 is resurrecting a CoreFx implementation of SecureString. The desktop version uses CryptProtectMemory at the SAME_PROCESS scope. The current corefx version uses CryptProtectData, which is a SAME_USER scope. There are two compatibility changes to consider: 1) CoreFx effectively allows a SecureString to now be marshalled into another process (though there are complicated things making that hard still) 2) The desktop and CoreFx versions might not have the same behavior under impersonation. At minimum a test should be done for behavioral differences across an impersonation boundary; and the SAME_PROCESS v SAME_USER impact should be considered. One solution may be to build UWP as CryptProtectData, but the full-Windows version as CryptProtectMemory. 8380 area-System.Net Add way to receive RemoteEndPoint from TcpClient I'm working on porting one of my networking libraries to .NET Core, and some of the changes made to sockets and TcpClient have made some information impossible to get. I was using a derived version of NetworkStream, however with the removal of the Client property, I could not create that anymore. I can work without that, but with neither NetworkStream or TcpClient providing the RemoteEndPoint of the socket, I cannot receive the remote address or remote port of the client. In addition, because of the removal of Async methods from Socket, I can't use raw sockets either. Any chance a way to get RemoteEndPoint data from a TcpClient or NetworkStream, a way to get the raw Socket again from TcpClient, or Task based async methods on raw Sockets? 8382 area-System.IO Add async overloads to BinaryReader/Writer Because I'd love to use it to read/write things, asynchronously from the network. 8385 area-Infrastructure "Skipping build of test assemblies when ""skiptests"" is specified" On Unix, one can specify the `skiptests` command line option to `build.sh`.

In other cases, default credentials would be sent even though CredentialCache.DefaultCredentials was not specified. The code was incorrectly comparing the proxy and server credential (ICredential interface) values against the DefaultCredentials object. Instead, the ICredentials.GetCredential() method should be called to compute the final NetworkCredential object. This takes into account the given uri and auth scheme. This PR fixes the logic by delay the setting in WinHTTP for releasing default credentials. This ensures that default crdentials are released when requested.

However, when I `dnvm use` to switch to `coreclr` runtime, then I've found that HttpClient invocations fail. At first this seems like this is a Kestrel issue, but please read my post through to learn my workaround. The workaround suggests this is an issue with HttpClient itself. To create this problem: - Run under `1.0.0-rc1-update2 coreclr`. I use `x86` for architecture, but I don't think that matters. - Execute an HttpClient request **in an async / await construct**. This part is necessary! - Perform back-to-back HttpClient POST requests that serialize payload (I have been using `Microsoft.AspNet.WebApi.Client v5.2.3` extensions, such as `PostAsJsonAsync`). I launch the test by typing `dnx test`, which launches xUnit. The first HttpClient request will work correctly. The next request will mysteriously receive a 404. When I insert fiddler to spy on traffic, it interferes by ""post-poning"" the problem; it allows two or three HttpClient requests to be processed before finally failing with a 404. Furthermore, Fiddler will only capture half or less of the traffic(!!!!) being received by Kestrel (even though all requests are coming from the same HttpClient object instance!). One of the 404 requests that was captured by both Fiddler and Kestrel looked like this: ``` PATCH http://localhost:60996/evt/Subscribers/bcf8edb0-dbae-4e83-bb8d-b5d966b2736b/AddNumbers HTTP/1.1 Content-Type: application/json; charset=utf-8 Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: localhost:60996 Content-Length: 15 [""303 2968199""] ``` Looks normal. On the Kestrel side, it looks like this: ``` info: Microsoft.AspNet.Hosting.Internal.HostingEngine[1] Request starting HTTP/1.1 PATCH http://localhost:60996/evt/Subscribers/bcf8edb0-dbae-4e83-bb8d-b5d966b2736b/AddNumbers application/json; charset=utf-8 verb: Microsoft.AspNet.Mvc.Routing.InnerAttributeRoute[0] Request successfully matched the route with name '' and template 'evt/Subscribers/{id}/AddNumbers'. verb: Microsoft.AspNet.Mvc.Infrastructure.DefaultActionSelector[0] Action 'ApiBasics.Controllers.SubscribersController.AddNumbers' with id 'b482e6ad-649c-4885-9b7d-12a25e3b422a' did not match the constraint 'Microsoft.AspNet.Mvc.ActionConstraints.HttpMethodConstraint' verb: Microsoft.AspNet.Mvc.Infrastructure.MvcRouteHandler[3] No actions matched the current request verb: Microsoft.AspNet.Builder.RouterMiddleware[0] Request did not match any routes. ``` It would seem this is a Kestrel problem, but consider the workaround. If I simply Dispose() the HttpClient after every request, and re-create it fresh for each subsequent request - then I can successfully run this code on coreclr. Furthermore, if I don't use async/await constructs with HttpClient, then this problem also does not appear. Evidently, there is some sort of state that HttpClient is retaining between calls. Again, this work-around is not necessary and the problem does not occur **if I use dnvm to switch to `1.0.0-rc1-update2 clr`** and then run my test again. I'm launching my test via xUnit. I have an xUnit `IClassFixture` which launches Kestrel. In other words, I am performing in-memory fast integration tests. The versions I am using for these two tools are: ``` ""xunit.runner.dnx"": ""2.1.0-rc1-build204"", ""xunit"": ""2.2.0-beta1-build3239"", ""Microsoft.AspNet.Server.Kestrel"": ""1.0.0-rc1-final"", ``` ## Work-around Test Code To simplify my ability to test the ""restart HttpClient"" work-around, I have been using this code: ``` public class AsyncClient { Uri address; HttpClient client; public AsyncClient(Uri baseAddress) { address = baseAddress; client = new HttpClient(); client.BaseAddress = baseAddress; } public async Task Request(Func> call) { HttpResponseMessage response = null; using (var client = new HttpClient()) { client.BaseAddress = address; response = await call(client); } return response; } } ``` The above `AsyncClient` is registered as a singleton in my IOC container. By simply commenting the ""using"" line in the `Request` method, I can toggle between a singleton `HttpClient` or a ""per invocation"" `HttpClient`. ## Further Anomaly Using the `AsyncClient` code shown above, I can ensure the `HttpClient` is fresh for every request - and this allows the `coreclr` execution to be successful. However, when I change the address of the server so that Fiddler can intercept traffic, then this 404 problem occurs all over again!!!! So if the `HttpClient` base address normally points here: ``` http://localhost:60996 ``` And I change that address (for Fiddler's sake) to this address: ``` http://localhost.fiddler:60996 ``` Then the same 404 appears after the third or fourth request! And this time, my ""workaround"" can't save me...the `coreclr` execution simply will not work...due to these 404 issues. No Fiddler for `coreclr` !!! Incidentally, if I switch back to the full `clr` runtime...my errors might be gone, but Fiddler still only captures half the traffic that Kestrel is successfully receiving.

Changes: - Added `using` statements - Indented the code (hence why the diff is so big, try adding ?w=1 to the end of the GitHub URL to unsee whitespace changes) cc @davidsh @stephentoub 8471 area-System.Net Fix translation in GetSocketOption with SocketOptionName.Error On Unix we're currently handing back the underlying errno value from the platform.

We discovered this because we still got ERROR_WINHTTP_TIMEOUT errors after about 20 seconds even after setting the 'Connect' timeout to INFINITE. We discussed this with the WinHTTP team and they told us that this timeout is essentially deprecated due to performance enhancements in the TCP stack. For the technically curious, here is the explanation. Underneath the 'Connect' timeout is really a set of TCP timeouts related to setting up the socket via the 3-leg SYN/ACK exchange. The TCP timeout is about retransmits with backoff and how many is tried by the winsock stack. The default of these initial packet exchanges is 21 seconds with 2 retransmits (3 overall SYNs) and initial RTO of 3 (3 + 6 + 12). So that explained the timeouts we saw during periods of high network congestion. There is no API exposed in WinHTTP to control those low-level TCP timeouts. And thus it doesn't make any sense to have a 'ConnectTimeout' on the WinHttpHandler class. 8504 area-System.Security Delete CryptoNative_GetStreamSizes Delaying the function removal until 1.1 to allow for a smooth RC2 to RTM upgrade path. 8505 area-System.Net Disable parts of the test build from projectreference->package dependency conversion.

Here's my original bug entry: https://bugzilla.xamarin.com/show_bug.cgi?id=37724 As per this article (https://en.wikipedia.org/wiki/IPv6_address#Link-local_addresses_and_zone_indices) the syntax of specifying IPv6 zone indices and link-local addresses depends on the platform. On MS Windows the index is determined by the interface number while on Unix-like OS's (including OS X) the interface name (ie. en0) is used. System.Net.IPAddress only has support for specifying the interface the MS Windows way in the form of it's ""ScopeId"" property which is a ""long"". So this causes issues on non-Windows systems and in some cases, specifically where the MS Windows notation is not supported as an alternate way of specifying the interface it renders this class completely useless. Even worse, IPAddress.Parse succeeds in parsing an IP Address with a zone index specified as name (ie. %en0"") but totally ignores/scraps the zone index resulting in a false positive. At least on OS X (can't speak for other Unix or BSD based platforms) one can alternatively specify the zone index using the index of the interface. This is not well known or widely used though and requires finding an interface's index instead of just using it's name. So on platforms where the number-based notation is available but not the default, IPAddress.Parse could be extended to look up the interface index using the System.Net.NetworkInformation.NetworkInterface class. On systems where this ""fallback"" isn't available this wouldn't work though and apart from introducing a new property and adjusting the parsing code I have no suggestion for this scenario. " 8510 area-System.Diagnostics Cleanup dependencies on System.Diagnostics.Contracts Code Contracts are not being maintained in .NET Core and `Debug.Assert` is being used in favor of `Contract.Assert`, yet many CoreFX components still depend on `System.Diagnostics.Contracts` in their implementation. https://github.com/dotnet/corefx/search?l=json&p=1&q=%22System.Diagnostics.Contracts%22&type=Code Could we start removing dependencies on `System.Diagnostics.Contracts` (similar to how most dependencies on `System.Collections.NonGeneric` have been removed) or is there a reason to keep the dependencies the way they are? cc: @weshaggard 8511 area-System.Diagnostics Add the notion of metadata to DiagnosticsSource DiagnosticsSource has been around for a while now and as more sites are instrumented and more listeners come online, it is becoming evident that there is a need for metadata to be provided as part of the system - specifically, the notion of collecting `timestamps`, `duration`, `correlationid` and possibly `stack`, `processid` and `threadid`. These concerns are currently being tracked in an inconsistent manner across the publisher and subscriber code bases and has lead to several problems (i.e. different listeners coming up with different durations or timestamps, correlations not being determined correctly, listening to more events than are needed just to calculate duration, etc). Hence, after seeing issues like #8498 arise, it has been determined that the correct place isn't in the publisher or the subscriber, but most likely in the underlying subsystem - DiagnosticsSource. This issue is to track this discussion and determine the best way to start including this data into the system. Considerations that need to be had are as follows: - Can we get these updates in place before RTM/RTW lockdowns? - Can we make these changes in a non breaking way, given the fact that people are already taking a dependency on DS today? - A possible solution here is to have two subscription methods which listeners can use, listen without metadata (what they would be using today) and listening with metadata. Other solutions are also possible. - Is there the need for the subscribers to dictate which metadata they would like collected (i.e. if no listeners want the stack, then the stack wouldn't be collected)? - Can the system be optimized so that to calculate durations, listener don't have to listen to both the `begin`/`end` events? - To do this work, do we need to take any extra dependencies, and if so does it matter? - Can correlations between `begin`/`end` events be provided in a deterministic way? Obviously given where things are at timing wise with release schedules, we need to see what we think is the right solution and what we can get done in the time we have. Assuming this work is done, we can also go through and cleanup some of the publishers code and simply things greatly. // @vancem @stephentoub (note this should be assigned to @vancem for the time being). 8515 area-Meta Cleanup ApiCompat baseline for 4.6.3+ TargetingPack Also includes APIs from #6936.

The core issue is that the ctor of `UdpClient` creates the socket. The `ExclusiveAddressUse` is a property that evaluates after the ctor, so it's too late. Today, this is accomplished by using the default `UdpClient` ctor, then setting a bunch of options on the socket/client and then calling `udpClient.Client.Bind(localEndpoint)`. This allows for the socket to be setup as a shared socket before binding. We need a way to create a `UdpClient` while specifying exclusive address use is false. One suggestion could be to add another ctor parameter with that flag. Another might be to add a collection of socket options. 8553 area-System.Net Fix WinHttpHandler default cred auth when server offers multiple schemes When a server offers multiple auth schemes, WinHttpHandler is supposed to select the more secure scheme regardless of the order of the authentication headers. So, despite a server offering Basic and Negotitate (in that order), Negotiate would be selected. When using default credentials, however, it was not calling WinHttpSetCredentials(null, null). This resulted in the first scheme offered by the server (Basic) to be attempted. But there were no credentials set and so a 401 resulted. Fix WinHttpHandler so that it will always call WinHttpSetCredentials even with default credentials. This ensures that the selected auth scheme (in this case Negotiate) is used correctly. Revised test configuration instructions. An IHttpModule is used for the test server endpoint to ensure that IIS will put 'Basic' first in the response headers. 8555 area-System.Net Change some System.Net.Requests tests to use LoopbackServer Moved LoopbackServer.cs to Common/tests path.

Currently in System.Collections.Immutable\src\System\Collections\Immutable there are a number of files that have names like ``` ImmutableHashSet`1+MutationResult.cs ``` which have unusal characters like ` and +. It turns out that these characters cause problem with the Nuget Symbol packages we generate in that they need to be escaped. See the package bin\symbolpkg\System.Collections.*.symbols.nupkg You will see that the special characters are escaped, in the nuget package archive. This in turn confuses the nuget source server. (basically source lookup for these files simply fail). While we could try to push nuget and all downstream components to support ` and + as normal characters, this seems like more trouble than it is worth. System.Collections.Immutable is the only assembly in CoreFX that does this. Thus my recommendation is to simply avoid the problem and reaname the source files to avoid ` and + (very easy). This will have no effect on the assembly, but it will make source code lookup work properly. Thus low cost, useful value. 8610 area-System.IO ZipArchive doesn't verify checksums when decompressing. The Zip specification includes a crc32 for each individual file entry header. When writing a ZipArchive, we calculate this crc32 and include it for each file. When reading/decompressing a ZipArchive, we read this crc32 from the file header but don't ever validate it.

The end result of this is that you can successfully unzip an archive that has potentially invalid data. Changing this behavior would introduce a large number of new errors and breaking changes.

It seems that if CFRunLoopStop is called too quickly after CFRunLoopStart is called, we may end up successfully calling CFRunLoopStop without actually terminating the CFRunLoopRun call which has, or is just about to, start. To work around this, I have added a call to CFRunLoopIsWaiting in order to ensure that the call to CFRunLoopRun has happened, and that thread is waiting for messages. This means that, when we finally call CFRunLoopStop, the call to CFRunLoopRun has definitely already begun and we can successfully terminate it. This seems to be entirely a timing issue. With a debug runtime, the tests run a lot slower, and the behavior is never encountered (no hangs). With an optimized runtime, it is much more likely to occur. Without this change, around 1 in 10 test runs would hang on my test laptop. With the change, I am not seeing any hangs, and I have run the tests >1000 times in a row. 8629 area-Serialization 1.

Historically we've blocked using legitimate paths by trying to guess up front. Across all of the platforms we don't have a rock solid way to know that a path will go over a particular API's limit. On Windows the historical ""limit"" has been MAX_PATH, but not all of the APIs enforce it. In addition, there is an ability to circumvent it for _some_ APIs with extended DOS device syntax (`\\?\`). Even if we did have a list of every API we called and what it supported: 1. That API's support could (and likely will) change 2. The real limits are based on complicated internal details that are difficult, if not impossible, to replicate (see [DOS to NT: A Path's Journey](https://blogs.msdn.microsoft.com/jeremykuhne/2016/05/02/dos-to-nt-a-paths-journey/)) 3. Lower level file systems (CDFS, UDF, NTFS, FAT16, ReFS, etc., etc.) impose their own limits which are nearly impossible to check with reparse points 4. Related to above we already get it wrong with path segments- not all file systems have a max of 255 characters It is particularly problematic with normalization methods that we provide (Path.GetFullPath). Checking there can block legitimate uses with other API's that don't have the limits we are claiming are system wide. PathTooLong should only throw from the actual platform invokes, which we already do.

The following code demonstrates the problem with all of the HttpClient *Async() methods when set to buffer in the response body. This test server will return response headers quickly. But will take 15 seconds to return response body. In these examples, we call GetAsync() and include the option (default) to read in (buffer into memory) the response body as well as response headers. Each test uses a different method to cancel the operation after 1 second. Either the .Timeout property or a cancellation token. In both case, we request cancellation after 1 second. But the GetAsync() task doesn't cancel until the 15 seconds has elapsed. This pattern works on .NET Framework (Desktop). Looking at the Desktop code, it is surprising that it works because the cancellation token passed into `HttpClient.GetAsync` is not actually propagated down thru the stack. The cancellation logic only works on Desktop because of a special internal method used by Desktop HTTP stack (HttpWebRequest).

If you are sending a request to a server over HTTPS which doesn't immediately require a client certificate on the initial handshake and the request entity body is non-trivial in size then the request will always fail. This is because when the server sends the SSL renegotiation request the client has already sent too much data for the server to buffer before it can receive the SSL renegotiation response. If you support HTTP and HTTPS on the same site in IIS, then you can't set certificates to be required, only accepted. When communicating with IIS/HTTP.SYS, 16KB is the amount of data that the client needs to send so that the connection can't be established. The `Expect: 100-Continue` header works around this issue by causing the client to hold off sending the entity body until the server sends a ""100 Continue"" status response. This allows the server to do the SSL renegotiation before it sends the ""100 Continue"" response and the connection/request succeeds. Without full support for this header, client certificates with an entity body > 16KB are going to be a fragile use case depending on server config and client/server latency.

Each task tries to select a value from a sequence using ExecuteScalarAsync. The important part of this repro: ``` c# using (var conn = new SqlConnection(connStr)) { var command = conn.CreateCommand(); command.CommandText = ""SELECT NEXT VALUE FOR TestSequence""; conn.Open(); await command.ExecuteScalarAsync(); } ``` ### Expected behavior Can retrieve 50 values in parallel for all platforms. It works on Windows 10-x64. ### Actual behavior On Linux, command execution hangs on executescalarasync. Subsequent attempts to open a connection will overwhelm the server until to refuses more connections. A few of the first calls to ExecuteScalarAsync may pass, but with in a few seconds, this simple app crashes as subsequent connections are rejected: ``` System.Data.SqlClient.SqlException : A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Regards, 8715 area-System.Net HttpRequestHeaders Date header Hello, Proposal: I think Date header in HttpRequestHeaders (and maybe other headers of DateTimeOffset type) must be of new DateTimeHeaderValue type which will be convertible to/from DateTimeOffset and string. Rationale: Many token based authentication schemes require client to send some hash/HMAC of request data. Value of Date header is almost always part of data to be hashed/HMACed. While values of other types of headers (like StringWithQualityHeaderValue) can be get by simply calling ToString() this is not the case for Date. So you'll have to read documentation on how dates are represented in HTTP headers and convert value exactly the same way. Or probably dig into source code of CoreFX to see how it's done. Abstraction leaked the bad way. As a side note, maybe it's good idea to provide type conversion operators for header value types, which will call ToString/Parse internally and ease one's life. 8716 area-System.Security System.Security.Cryptography.Native OSX build errors.

Currently, it's a runtime `PlatformNotSupportedException`. This breaks [StackExchange.Redis](https://github.com/StackExchange/StackExchange.Redis) on at least OS X and Linux, you can see the issue filed here: https://github.com/StackExchange/StackExchange.Redis/issues/410 The best notes for this are in the https://github.com/dotnet/corefx/commit/30bd4b79185d83f269f6a6e432881998a0158178 commit, copied here for ease of consumption: > On unix, once connect fails on a socket, that socket becomes unusable for further operations, including additional connect attempts. This is at direct odds with Socket's instance Connect methods, some of which allow for multiple connect attempts, either due to multiple IPAddresses being provided or due to a string hostname / DnsEndPoint being provided that could then result in multiple IPAddresses to be tried. > > We've explored multiple workarounds for this, all of which have problems. The workaround still in the code involves creating a temporary socket for each address, connecting to it, and if that's successful then immediately disconnecting and connecting with the actual socket. But that causes mayhem for a server not expecting that pattern, e.g. that fails if the client disconnects and attempts a reconnect. > > This leaves us with a few choices, none of which are great: > 1. Remove the offending Connect instance methods. Ideally they'd be replaced with static methods, which can be implemented with POSIX-compliant behavior. But these methods are heavily used and work on Windows. > 2. Always throw from the instance Connect methods when there's a possibility that multiple addresses will be tried, e.g. from Connect(IPAddress[], ...) but also from Connect(EndPoint) if a DnsEndPoint is specified. This will break a lot of existing code, but it's also predictable, and developers will know quickly when using a problematic API and move away from it to supported patterns. > 3. Throw from the Connect methods if multiple addresses are actually supplied, e.g. calling Connect(IPAddress[]) with an array of length 1 would work but an array of length 2 will fail. This will allow a lot more existing code to work, but it's also very unpredictable, e.g. if a string host is provided and gets mapped by DNS to a single IPAddress in the test environment but then multiple IPAddresses in the production environment, everything will work fine locally but then fail in production. > 4. When presented with multiple addresses, try the first one, and if it fails, then throw a PlatformNotSupportedException. This may be slightly more predictable than (3), but is still unpredictable, e.g. if a DNS server returns addresses in a different quantity or order from another server. Currently option 2 is implemented, which breaks this codepath: [`SocketTaskExtensions.ConnectAsync(this Socket socket, string host, int port)`](https://github.com/dotnet/corefx/blob/d0dc5fc099946adc1035b34a8b1f6042eddb0c75/src/System.Net.Sockets/src/System/Net/Sockets/SocketTaskExtensions.cs#L60) [`Socket.BeginConnect(string host, int port, AsyncCallback requestCallback, object state)`](https://github.com/dotnet/corefx/blob/c2a6a128a6d2cdbad3a8be663d027152ca9d63bc/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L2304) This hits [line 2334](https://github.com/dotnet/corefx/blob/c2a6a128a6d2cdbad3a8be663d027152ca9d63bc/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L2334): `ThrowIfNotSupportsMultipleConnectAttempts();` The _exact_ codepath doesn't matter, because several more feed into this one. In fact even if you call [`BeginConnect(EndPoint remoteEP, AsyncCallback callback, object state)`](https://github.com/dotnet/corefx/blob/c2a6a128a6d2cdbad3a8be663d027152ca9d63bc/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L2262), it's still calling [`BeginConnect(dnsEP.Host, dnsEP.Port, callback, state);`](https://github.com/dotnet/corefx/blob/c2a6a128a6d2cdbad3a8be663d027152ca9d63bc/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L2293) in the host case anyway. So even using the explicit overload of a single endpoint, it still breaks. I would like us to change to option 3 in the comments above, only throwing **for the case that breaks**. The current state needlessly breaks existing code for no real reason. The comments in option 3 about deployments being a surprise break is perfectly valid, but it's no worse than option 2 and we're seeing that break in actual runtime usage already out in the wild. If we can't prevent the issue in general (it looks like all practical options have been exhausted there), I would argue for 2 changes: 1. Only break when multiple endpoints are _actually_ passed in. 2. Provide a much clearer exception message on why we're throwing, [here's a link to the current one](https://github.com/dotnet/corefx/blob/183f7fb0136d8b25f7e0194df4f18930d4199939/src/System.Net.Sockets/src/Resources/Strings.resx#L277). 8771 area-System.Reflection Downgrade S.R.Metadata to v1.2.1 and internalize public surface for NET Core 1.0.0 RTM "The changes under development for S.R.Metadata 1.3 are aligned to the VS ""15"" schedule and there are insufficient resources to lock them down now.

Right now, we are using NetDatacontractSerializer to send exception over wire as the client doesn't know the type of exception beforehand.

However, since type information is not embedded in the serialized object, it throws an exception when we are trying to deserialize. In full CLR, DataContractResolver with dataContractSerializer would've solved the problem. Though DataContractResolver is available in coreCLR, there is no constructor of DataContractResolver using DataContractResolver. Is this the intended behavior.

P.S I am using .NET core 1.0.0. version 8841 area-Infrastructure Stop pulling live CoreCLR We've been hitting issues left and right recently because some of our jobs pull live CoreCLR bits and that breaks us. We've hit issues due to the mscorlib rename, changes that expose test issues, and the inability to get a consistent mscorlib/coreclr pair because of how we pull from jobs. Windows, OSX and Ubuntu 14.04 consume CoreCLR from packages. It's time that we do the same for the other distros. If we are concerned about trying to get an early read on if CoreCLR changes are going to break CoreFX, there should be tests in CoreCLR that use a LKG test drop and run with a live CoreCLR. 8848 area-System.Linq LinQ GroupBy fails with TResult I have the following Linq Expression (after loading elements from the database): ``` C# var result = memberships.GroupBy( m => m.Role, (role, ms) => new RoleUsage { Role = role, MemberCount = ms.Count(m => m.StructuralUnitId == query.StructuralUnitId), InheritedMemberCount = ms.Count(m => m.StructuralUnitId != query.StructuralUnitId) }).ToList(); ``` Where `memberships` is a `List` of _non null_ `Membership` instances. `Role` and `Membership` are simple classes. Running that Linq will fail with a NullReferenceException in the inner `Count(m => m..)` Expression, since `m` is `null`. We first thought, it would have to do with EF, which loads the `Memberships`, but it's not the case. Appearantly somewhere in Linqs GroupBy something goes wrong, since pointing with the Debugger on `ms` states Powers of 2 in elemt Count, with lots of empty entries. Further Investigation leads to `corefx / src / System.Linq / src / System / Linq / Lookup.cs` and especially `ApplyResultSelector` (Line 240), which applies the result selector to the Elemtents of a Grouping. Unfortunately that `_elements` (Line 253) appearantly contains null entries, which should not be present. 8853 area-System.Console Implement Console support for netcore50 The Windows implementation currently used for netcore50 will fail the WACK check as it calls a number of APIs unsupported by UWP. This commit adds a separate netcore50 build that stubs out the API calls and replaces them with PlatformNotSupportedExceptions or no-ops where appropriate. The result is a platform-agnostic version of System.Console that can be used anywhere but is severely stripped of functionality. - Where possible the behavior of a redirected Console operation will attempt to mimic that of a Unix redirected Console operation. Otherwise it will throw. - Encoding is fixed to UTF8. Attempting to set the Console encoding will no-op. - Added a section in the packaging build for the new netcore50 specific binary - Input/Output redirection and subsequent reads/writes work as expected. Discussion points: - This does not add System.Console to the UWP meta-package. That is mostly because I do not know where the UWP meta-package lives. - This does not redirect Console.WriteLine to Debug or ETW. Those functions currently throw PlatformSupportedException on a non-redirected stdout. I'm going to push an update that special-cases them to call Debug.WriteLine if the Console isn't redirected if we're sure that is the most useful alternative. @ericstj @weshaggard resolves #5875. 8855 area-System.Reflection Any reason System.Reflection.TypeExtensions can also target Profile151 I see no reason why it can't profile 151 when it already targets a lot of similar profiles. 8856 area-System.Data SqlClient high memory consumption when there is disk IO saturation ### Repro environment - Windows 10 - LocalDb - [npm](https://nodejs.org/en/) - loadtest: `npm install -g loadtest` - dotnet 1.0.0-preview2-002823 ### Scenario description Stress test for ASP.NET and Entity Framework. The code is [here](https://github.com/aspnet/Performance/tree/dev/testapp/BasicApi). There's a server side and a client side to the test. For the server side, execute the app with `dotnet run -c Release`. For the client side, execute `.\loadtest.ps1 -iterations 50000 -rps 500` The `-rps 500` part is important, as the issue only manifests itself when disk IO is saturated. ### Observed results Once the test starts running we're reaching disk IO saturation almost immediately. The memory increases dramatically, up to 1 GB in private bytes when loadtest is run with the parameters stated above. After the test is up, we force GC collection once and take some measurements of the managed heap: - Gen 0: 49,440 bytes - Gen 1: 384,344 bytes - Gen 2: 5,178,176 bytes - LOH: 6,375,520 bytes Totalling roughly 12 MB. That said, the application is currently taking 959 MB in total committed memory. I'm assuming then that there's native memory being held. A profile trace of the execution shows that most of the time is being spent in `ReadSniSyncOverAsync`. ### Expected results We expect the memory to not grow as much as it's doing now. ### Notes After forcing GC collection a number of times, we end up bringing the committed memory down to 515 MB and it stabilizes there. The managed heap shrinks from 12 MB to 10 MB. 8857 area-System.Threading Regression threading.NamedMutex.test1 (from (empty)) http://dotnet-ci.cloudapp.net/job/dotnet_coreclr/job/release_1.0.0/job/debug_centos7.1_prtest/11/testReport/junit/threading/NamedMutex/test1/ Stacktrace MESSAGE: 'paltest_namedmutex_test1' failed at line 355.

They pass without issue locally. 8884 area-System.Net Delay HttpResponseMessage publishing in CurlHandler until all request data sent "libcurl uses a callback model, where it asks for request data when it wants to send it and passes back response information as it's received. It doesn't enforce any significant constraints on top of this, such that if a server sends response headers and even body before all of the request information has been received, libcurl will dutifully pass that data back to the application as it's received. CurlHandler responses to receiving response body data by completing the SendAsync with the HttpResponseMessage, which means it can complete this task after receiving all response headers but in some cases before all of the request data has been sent. This can actually be beneficial for some scenarios, however with the current HttpClient implementation, it can cause a problem: the request message is Dispose'd of as soon as the SendAsync Task completes, which means HttpClient might dispose of the request message while we're still trying to send data from it. There are two high-level solutions here: 1. Stop always disposing of the request message when SendAsync completes, leaving such disposal up to the consumer (or moving the responsibility to the handler), and state that it's allowed for a handler to complete the SendAsync task when all response headers have been received even if all request data has not yet been sent. 2. Force CurlHandler to not complete the SendAsync task until all request data has been sent, even if the response headers were completed before then. While in the future I would like to see us go with (1), as it opens up additional scenarios and simplifies this implementation, a decision was made to go with (2) for now. This PR implements that. There are two commits: - The first commit adds a bunch of additional tracing. This was beneficial in tracking down the cause of the original problem as seen in some WCF workloads, and it's useful to check it in to help with future investigations. - The second commit adds the completion delay to SendAsync. This is done primarily in the routine that's used to complete the SendAsync task and publish the response message: it now keeps track of whether it was previously invoked, and if it wasn't, it proceeds to do the publishing... but if a copy operation is still in progress, rather than doing the publishing directly, it hooks up a continuation to the copy task so that the publishing will be done when the copy completes. It also disables the ""Expect: 100-continue"" header that libcurl uses with posts by default, as otherwise libcurl may decide in certain situations not to send the payload, and if we've already kicked off the copy operation, we could end up hanging until the operation times out (such hanging is the biggest risk with this change). I also added several additional tests. cc: @davidsh, @ericeil, @mconnew, @KKhurin, @bartonjs Fixes https://github.com/dotnet/wcf/issues/1211 " 8887 area-Serialization Fixed issues in NetNative.

It turns out there is one extra case. Space for the file is not guaranteed to have been allocated until calling close() or CloseHandle() and may not in fact exist. This means that writing a file swallows knowledge of certain errors that should be thrown. Close() must throw to catch write errors Dispose() must _not_ throw to avoid problems with using() {} blocks. In effect Dispose() is { try { Cose(); } catch (IOException){}} (omitting certain details of the dispose pattern for clarity) The code to replace a file safely was: using (f = new System.IO.FileStream(""name~"", ...) { /\* write contents */ f.Close(); } System.IO.Move(""name~"", ""name""); But now that doesn't work because Close() can't be there to error out.

If you invoke an async method in a UI app, and try to fetch the .Result of the returned task before it is completed, you’ll get a deadlock. - `.GetAwaiter().GetResult()` will force a blocking value return if required - An expected test to see if the result is ready without exceptions may be `task.IsCompleted`, however it should really be `task.Status == TaskStatus.RanToCompletion` An alternative `bool TryGetResult(out T value)` would be a safer option increasing the chance of writing correct code. It would return `true` if the task has `RanToCompletion` with the result in the out param. It would return `false` if the task hadn't completed (or was cancelled/faulted, maybe throw exception then) " 8935 area-System.Net Dispose of request HttpContent after buffering response Related to: https://github.com/dotnet/corefx/pull/8884 and https://github.com/dotnet/corefx/pull/8894 Both of those PRs attempt to fix the issue described in https://github.com/dotnet/corefx/pull/8884. The first does it by delaying the completion of the HttpClientHandler's SendAsync task until all request data has been sent. The second does it by moving the responsibility for Dispose into the HttpClientHandler, which can then do it when it knows it's done with the request content. Both of those changes carry some risk. In contrast, this PR is a very low-risk change, which just moves the request content Dispose done by HttpClient to be a bit later, though it's only a partial mitigation rather than an actual fix. For several of the methods on HttpClient, e.g. GetAsync, PostAsync, etc., the default mode is to buffer all of the response data (HttpCompletionOption.ResponseContentRead), and in the rare situations where a server does start sending a response body before it's received all of the request body, it will still likely not send all of the response body until it's received all of the request body. As such, if we delay the disposal of the request content until after we've finished buffering the response, the chances of hitting an issue here are further reduced. (This doesn't solve the issue for WCF; WCF would still need to take a separate fix to workaround the issue, but it would hopefully mitigate an already rare case to the point where it's unlikely to be impactful.) cc: @davidsh, @cipop, @ericeil, @mconnew, @KKhurin 8941 area-System.Net HttpClient not overwriting RequestURI after server redirect on non-Windows Scenario: 1) Client sends GET to server, server sends 302 response. 2) Client sends GET to redirect location and completes the request but the RequestURI is not updated Example: ``` 1): Request URL:http://localhost:5000/ Request Method:GET Status Code:302 Found Remote Address:127.0.0.1:5000 2): Request URL:http://localhost:5000/hello Request Method:GET Status Code:200 OK Remote Address:127.0.0.1:5000 ``` The expected content of the `HttpResponseMessage` is: ``` Response.RequestMessage: Method: GET, RequestUri: 'http://localhost:5000/hello', Version: 1.1, Content: , Headers: { } Response: Hello world StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Date: Sat, 28 May 2016 02:18:13 GMT Transfer-Encoding: chunked Server: Kestrel } ``` This is correct and what I see on Windows.

We now allow any url that TryCreate will parse using the current url as a base. - We were only handling a subset of redirect status codes as redirects, trying to second-guess which status codes libcurl would redirect for, e.g. 300 wasn't being treated as a redirect with regards to our processing of it (it would redirect but we wouldn't reconfigure some of our state). We now let libcurl do all the work. - We should have been playing it safer with regards to clearing out credentials if we weren't sure a Uri redirect location was valid. Now we do. - We were tracking state unnecessarily that we should have instead been asking libcurl for, e.g. the last url used in a redirect. This also caused us to store the wrong RequestMessage.Uri in some cases where a location header came in but we didn't actually follow it. cc: @davidsh, @ericeil, @JunTaoLuo, @bartonjs Fixes https://github.com/dotnet/corefx/issues/8941 8947 area-System.Net MaxAutomaticRedirections behavior difference between .NET Framework and .NET Core "Repro: ``` C# using System; using System.Net.Http; class Program { static void Main() { var c = new HttpClient(new HttpClientHandler { MaxAutomaticRedirections = 3 }); Console.WriteLine(c.GetAsync(""http://corefx-net.cloudapp.net/Redirect.ashx?statuscode=302&uri=%2FEcho.ashx&hops=4"").GetAwaiter().GetResult().StatusCode); } } ``` With the .NET Framework, this prints out ""Redirect"".

However, when executing a multi-statement command (e.g. `UPDATE xxx; UPDATE xxx`), this property provides an aggregation of all rows across statements. There's no programmatic way to get records affected per statement. For an example of why this might be useful, see [EFCore's modification command batch](https://github.com/aspnet/EntityFramework/blob/dev/src/Microsoft.EntityFrameworkCore.Relational/Update/AffectedCountModificationCommandBatch.cs). One of EFCore's major new features are command batching (i.e. the use of multi-statement commands), but in order to implement optimistic concurrency it needs to know, _for each command_, how many records were affected. For SqlServer this is implemented by sending `SELECT @@ROWCOUNT` after each update, and parsing the results. PostgreSQL has no equivalent SQL query, so in Npgsql I actually developed a statement-by-statement RecordsAffected mechanism to support this. In a nutshell, a collection of NpgsqlStatements is exposed by NpgsqlDataReader, and each object has its own RecordsAffected. Let me know if you want more detail. Note that this is somewhat related to #3688, where the possibility of a better API for command batching is discussed (the latter may/could also depend on multiple DbStatement instances being managed within a single DbCommand). 8955 area-System.Data API for writing parameters without boxing In the current ADO.NET API, writing a parameter to the database involves passing it through an object. This implies a boxing operation, which can create lots of garbage in a scenario where lots of value types (e.g. ints) are written to the database. A generic subclass of DbParameter could solve this, if properly implemented by providers. 8956 area-System.Net Fix client certificates-related seg fault in HttpClientHandler Using HttpClient with client certificates on Unix would crash when making a request, waiting for several minutes, and making another one. The issue was that our client certificate code was disposing of SafeHandles for resources we'd logically transferred ownership of to OpenSSL. The underlying connection cache would keep the connection open for any requests made within a few minutes, but once the connection's timeout expired, it would be culled from the cache, and the resources associated with these handles would then be re-freed, resulting in a seg fault (either immediately when closing or when we next tried to use an SSL connection). The fix is simply to not dispose of the resources we no longer own. cc: @bartonjs, @billwert, @ericeil Fixes https://github.com/dotnet/corefx/issues/8958 8960 area-Infrastructure Building System.Data.SqlClient.sln in parallel often fails "When I build System.Data.SqlClient.sln without parallelization, it works fine (but notice the same file is built twice): ``` >msbuild /v:m /t:rebuild System.Data.SqlClient.sln Microsoft (R) Build Engine version 14.0.25123.0 Copyright (C) Microsoft Corporation.

(Note: I'm aware that `EqualityComparer.Default` already specializes for enums, however I still think this would be an API addition worth pursuing. Additionally, `Comparer.Default` [does not](https://dotnetfiddle.net/vlr0UV) specialize for enums and falls back to boxing.)

However, they will actually only support versions 2.0 and up. This would mean that zips created by the core version of ziparchive will be improperly unzipped by unzippers from versions 0.0 to 2.0 (1989 to 1993). This commit fixes a regression from the full framework that sets the min to 2.0. The windows zip utility also sets the version to 2.0. @ericstj 8987 area-System.Console Port to release/1.0.0: Implement Console support for netcore50 port https://github.com/dotnet/corefx/pull/8853: The Windows implementation currently used for netcore50 will fail the WACK check as it calls a number of APIs unsupported by UWP. This commit adds a separate netcore50 build that stubs out the API calls and replaces them with PlatformNotSupportedExceptions or no-ops where appropriate. The result is a platform-agnostic version of System.Console that can be used anywhere but is severely stripped of functionality. - Where possible the behavior of a redirected Console operation will attempt to mimic that of a Unix redirected Console operation. Otherwise it will throw. - Encoding is fixed to UTF8. Attempting to set the Console encoding will no-op. - Added a section in the packaging build for the new netcore50 specific binary - Input/Output redirection and subsequent reads/writes work as expected. @weshaggard @ericstj 8990 area-System.Net Remove innerloop dependencies on www.ssllabs.com We have several tests that make HTTP calls during System.Net.Http.Functional.Tests out to www.ssllabs.com, which has SSL endpoints for different SSL protocols. This commit avoids using that server during innerloop tests. Some of the dependencies are removed entirely, by using a localhost SSL server instead. The remainder are made outerloop. cc: @bartonjs, @davidsh, @cipop, @ericeil 8995 area-System.IO ZipArchiveEntry always writes Unicode bit for entries Initial discussion here: https://github.com/dotnet/corefx/pull/8986#issuecomment-222739144 Previously we would only write the Unicode bit if 1. The system default was UTF8. 2. Any characters in the string were greater than 127. It turns out that neither of these were very common so before the bit was rarely set, now it is always set. /cc @ianhays 8996 area-System.Net Fix some memory leaks in WinHttpRequestState When HTTP requests are canceled, we are leaking WinHttpRequestState objects and some child objects. Since WInHttpRequestState is strongly pinned, it's important to release things as soon as possible. This fix addresses part of the leaks involved in #8819 by removing references to some fields in the state object related to the request/response phase (CancellationToken). In addition, this fix addresses some cases where the state object is created and pinned but the request is canceled before we hook up the state object to the WInHTTP status callback. Because of not being hooked up yet, the state object won't get HANDLE_CLOSING notifications and remains pinned forever. We now pin the state object later when we're sure that we've hooked up the status callback. I also added some DEBUG tracking to help diagnose the rest of the leaks of #8819. 9002 area-System.Net If we don't expect UDP packets to be received, don't send redundant packets. "Fixes #8636. On OSX, if a UDP packet is actively rejected, a subsequent send on the same socket can result in a ""connection refused"" error. This change avoids that error for the cases where we're intentionally sending packets that might be rejected. @stephentoub " 9003 area-System.Net System.Net.Http.HttpClientHandler.CookieContainer is empty in a UWP app when cookies are set on 302 redirect response When the System.Net.Http.HttpClient class - with a HttpClientHandler is used from a UWP, the response cookie collection returned is empty. **This happens when the cookies are being set on a 302 redirect response.** When you collect a network trace, you should notice the below request/response pattern: # Request: GET _location_ HTTP/1.1 Host: _host_ Connection: Keep-Alive ..._other request headers_ # Response: HTTP/1.1 302 Object moved Set-Cookie: name=value; Location: _redirect location_ ..._other response headers_ The problem happens because the default behavior of the HttpClientHandler is to perform auto-redirection. With this setting, the .NET layer does not get to see the cookies in the redirect response leading to the buggy behavior. 9004 area-System.IO Allow writing an ASCII ZipArchive ZipArchive currently always sets the Zip header Unicode bit. This is a regression from the net46 version that set the bit based on the current default encoding page set. This commit modifies the behavior to default write ASCII whenever possible and only write/set Unicode when it is necessary or explicitly asked for. - When encoding an entry name, we check if it contains any characters outside 32-126. If it does, we encode it as UTF8. If it doesn't, we encode it as ASCII. - Decoding is unchanged. If the encoding isn't set, then we assume UTF8. This is so we have the widest range of effective readability and because we cannot represent values outside of the ASCII 32-126 range from CP437 @ericstj resolves #8995 9006 area-System.Net CurlHandler completes SendAsync task even if request content not fully sent This is a feature or a bug depending on who you talk to. CurlHandler completes the Task returned from SendAsync when all of the response headers have been received. That's by design. However, it does this regardless of whether all of the request content has been received. While rare, it's possible a server might send the response headers and even some or all of the body before the request content has been sent/received, e.g. in a streaming scenario where it was echoing/transforming/etc. the request content out as response content. WinHttpHandler and the implementation on desktop complete the SendAsync task only once all of the request content has been sent and all of the response headers have been received. The CurlHandler design is potentially problematic, however, as HttpClient explicitly disposes of the request content once the SendAsync task completes. If that task completes and the request content is still being sent, obvious problems can result. Several potential solutions: - Modify HttpClient to stop Dispose'ing of the request content, e.g. https://github.com/dotnet/corefx/issues/1794 - Moving the responsibility for Dispose'ing of the HttpContent to the HttpClientHandler, which can know when it's safe to dispose, e.g. https://github.com/dotnet/corefx/pull/8894 - Modifying CurlHandler to only complete the SendAsync task once the request content has all been sent, e.g. https://github.com/dotnet/corefx/pull/8884 9008 area-System.Net Socket.Handle isn't public *and* no access to SIO_KEEPALIVE_VALS / SIOCKEEPALIVE via Socket Got here looking for how to call ioctl(SIOCKEEPALVIE) / WSAIOCTL(SIO_KEEPALIVE_VALS).

Let's say that in six months it's possible to link against the BCL reference assemblies; you compile a dll, which can now be used on the various platforms and appmodels of the core CLR. So: what happens to code which calls System.DoesntWorkOnLinux? Or in the case of UWP, System.IO? As a library author, I won't have the capability to test every current and future platform. How should I go about building packages which do not throw PlatformNotSupportedException in an unexpected new environment? Can netstandard help here? It's not yet clear how it will relate to mscorlib - and some problems would still exist, like the one with System.IO in Store apps. 9041 area-System.Net Flow HttpClient timeouts and cancellation to the response stream When using a timeout and/or a cancellation token with a buffered HttpClient operation, the cancellation/timeout doesn't flow through to the actual read/write operations on the underlying streams. This fixes that. cc: @davidsh, @cipop, @ericeil, @bartonjs Fixes #8663 9043 area-System.Net Reduce System.Net.CredentialCache allocations This PR is broken up into multiple commits to make it easier to review... - The first two commits add some more tests and modifies an `ArgumentException` to include the param name using `nameof`. The tests in the first commit pass before and after the rest of the changes. - The next commit changes `CredentialCache`'s dictionaries to be lazily allocated. `CredentialCache` has two backing dictionaries: one is for Uri-based protocols like HTTP/HTTPS used by `HttpClient`, the other for Host/Port-based protocols like SMTP, used by `SmtpClient` in the full framework (but not in CoreFX as `SmtpClient` hasn't been ported yet). While it's possible that both types of protocols could be used at the same time with the same `CredentialCache` instance, it's more likely that only one dictionary will be used per instance. Instead of always allocating both dictionaries up-front, lazily allocate the dictionaries only when needed. - The next commit avoids the array allocation/copying in `CredentialCache`'s enumerator, using the dictionary enumerator(s) instead. - The next commit reduces allocations in `CredentialHostKey`. `CredentialHostKey` can be a struct instead of a class. Unlike with the Uri-based dictionary, there's no need to enumerate all items in the Host/Port-based dictionary to find the greatest prefix length. Instead, we can look up the item in the dictionary directly. There's also no need to cache the hash code. Allocations associated with `ToUpperInvariant().GetHashCode()` can be avoided by using `StringComparer.OrdinalIgnoreCase.GetHashCode()`. - The next commit reduces allocations in `CredentialKey`. Unlike `CredentialHostKey`, I've left `CredentialKey` as a class for now, as the dictionary needs to be enumerated to find the longest matching prefix, and I was concerned about potential perf degradation due to copying a large struct. However, there is still room for improvement. The `AuthenticationType.ToUpperInvariant().GetHashCode()` allocation can be avoided in `GetHashCode` by using `StringComparer.OrdinalIgnoreCase.GetHashCode(AuthenticationType)`. There's no need to include the length in the hash code, as the hash code for the Uri is sufficient. And, there's no need to cache the hash code, which allows us to at least reduce the size of `CredentialKey`. - The last commit contains some minor cleanup while making changes in this file. cc: @stephentoub, @davidsh 9044 area-System.Net Port System.Net.Http UWP tests /cc @davidsh Requires NetNative test execution support. 9045 area-System.Net Enable System.Net tests to run against NetFX /cc @tarekgh @davidsh An example is already available in `System.Globalization.Calendars`.

These include both the outer-loop tests as well as tests requiring more complicated setup and fixed SKUs such as perf. Here is a list of requirements that our team brainstormed a while back: ## Network Scenarios - Internet scenarios - Use a set of publicly available, always available Azure servers. - Allow `localhost`, local network or private Azure servers. - Enterprise scenarios (auth, IPSec) - Use `localhost` servers - Use local network servers - Use an Azure closed test environment - Performance/stress scenarios ## Test Server Requirements - Scripts should allow deployment on `localhost` as well as a specific on-prem machine or an Azure account. An example of such deployment is available at https://github.com/davidsh/corefx-net-testservers. - Server configuration scripts (both for local and remote deployments) - Use Bash/Powershell - Scripts should be able to both install and uninstall the server. - Ensure a clear state of the machine after uninstall. ## Test Client Requirements - Standardized script naming and location will allow for automatic prerequisite installation/cleanup. - Client prerequisite scripts: install and cleanup - Use Powershell/Bash - Will run as `Administrator` / `root`. ## Test Execution - Endpoint configuration will be made through Environment variables (see #2383). - A single script will be used to: - set the environment variables (a `.gitignore`d override file could allow developers to set up their own custom environment) - detect and install prerequisites - run selected tests - uninstall prerequisites - Proposed prerequisite script location and naming: - contract_name\tests\scripts\client - setupclient.ps1(.sh) [-u(ninstall)] - contract_name\tests\scripts\server - setupserver.ps1(.sh) [-u(ninstall)] 9049 area-System.Net Port System.Net.WebSockets.Client tests /cc @davidsh The following tests need to be ported: - [ ] Performance tests - [ ] NetNative tests - will be part of 2.1 work - [x] Server code and scripts 9053 area-System.Runtime MathTests.Pow test failing after recent coreclr change e.g. http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/centos7.1_debug_tst/558/consoleText http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/fedora23_debug_tst/167/consoleText http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/ubuntu16.04_debug_tst/347/consoleText ``` System.Tests.MathTests.Pow [FAIL] Assert+WrapperXunitException : File path: D:\j\workspace\fedora23_debu---1725fa63\src\System.Runtime.Extensions\tests\System\Math.cs.

Since the release of Windows 10 IoT Preview Version and announced support for Raspberry Pi Products many developers want to use it in a commercial way but the current build does not inherit the full core.

Using an additional WCF Service and communicate over REST-API is not the proper way to transfer Data in a company.

Ideally we'd find some mechanism to be notified by libcurl of end-of-headers (including end-of-headers for the final request when doing automatic redirection) so we can publish then, in case there's a delay between the last byte of the headers and the first byte of the body.

When using a timeout and/or a cancellation token with a buffered HttpClient operation, the cancellation/timeout doesn't flow through to the actual read/write operations on the underlying streams. This means that on Windows, doing a basic operation like GetStringAsync with a server that pauses for arbitrarily long periods of time while sending the response body won't cancel or timeout until it sends more data.

When we add the extra chain certificate to the SSL handle, we're transferring ownership to that handle, which we subequently dispose... but we don't mark the original SafeHandle as invalid, so it eventually gets finalized and we end up double-free'ing, leading to seg faults and other badness.

This issue is currently ""determine if there really is a problem"", with the implicit ""if there was, fix it"". This is somewhat hard to test, since the only way to get the intermediate certs on the request given the current API (I think) is to have them in a CA store; but if they're in a CA store we'll already find them when we chain walk on the receiver side. If the client API made guarantees about when the chain was walked then it could be [OuterLoop] managed by adding intermediates to the store, setting up the client, removing the certs from the store, and letting the request initiate.

Today, in the new build pipeline, we have triggers set to build CoreFX 4 times a day, every day, and CoreCLR 3 times a day, every day.

As we can launch these on demand and have results in an hour, there's less need to be doing them proactively. - Don't build over the weekend. - Have automation which auto merges green dependency updates. - Have automation which closes old dependency updates with no comments/additional commits.

In the .NET ecosystem, for years, it has been striking that the framework was not supporting JSON in a built-in way. As a result, `Newtonsoft.Json` is now the No1 package on Nugget. I suggest that the foundational libraries should include a `System.Json` library with an API compatible with `Newtonsoft.Json`. Indeed, as it stands Json.NET represents a tax that every .NET developer need to pay: you have to discover first _why_ there is no built-in way to deal with JSON, then you have to discover that this one specific third party package is worthy to be trusted. I am not dismissing the quality of this excellent package, but this massive hit primarily demonstrates that JSON should be part of the foundational libraries of .NET. Then, taking the longer view, I am worried - and I believe others should be - about the long term implications of having such a _narrow_ yet _mission-critical_ library developed and maintained separately. .NET Core can be a viable economic product to maintain over time even without the backing of Microsoft. However, Json.NET _alone_ is not economically viable, not even through commercial support, not only 10 years time scale anyway. The project might or might no go the way ServiceStack went (another great project by the way). Also, the commit profile of this project, with the _first contributor having literally over 100x more commits than the second_, a scenario ala NDoc is not to be ruled out either. Presently, Newtonsoft is taking the path of building complementary products on top of Json.NET, which again is very good, yet should not be relied upon for the future of .NET. Opening .NET to the community is great. However, the fundational libraries should cover the _very basic_ use cases. XML is covered, JSON should be as well. In particular, ""outsourcing"" narrow yet critical components is paving the way for upcoming messes ala left-pad. Ideally, `System.Json` would be API-compatible with `Newtonsoft.Json`. There are multiple ways to achieve that. Starting a discussion on this precise matter between corefx representants and James Newton-King would be a start.

and i need to do with **.NET Core** in vs2015. Since i am new to .NET Core, i am unable to do it on my own and i didn't find good useful links that address my need. Can anyone set me on the path by providing sample applications or useful links ?Thanks in advance. P.S. I tried randomly some console application(Not sure if it is correct) but when i am adding Microsoft.Net.Http dependency to the project.json, i am getting an error like This dependency cannot be supported on .NET Core framework. 9218 area-System.Net Allow Socket.Connect{Async} to be used with a string-based IP addresses "As outlined in https://github.com/dotnet/corefx/issues/8768, on Unix we don't currently support using the instance Connect/ConnectAsync methods that take a string host or a DnsEndPoint, because they could map to multiple addresses, which means we might need to try reconnecting on the same socket after a failed attempt, and that's not supported with BSD sockets. They are potential workarounds we can explore as outlined in that issue, but they're non-trivial and/or have undesirable ramifications. However, one simple thing we can do is allow a string/DnsEndPoint version of an IPAddress, e.g. just as someone can provide an IPAddress, they can provide a string version of that IPAddress, such as ""127.0.0.1"". This is a common thing to do, and we can make it work just by attempting to parse the address.

Thus, getting properties and/or events via reflection fails as following: ``` csharp interface IFoo { string Bar { get; set; } }; IFoo proxy = DispatchProxy.Create(); PropertyInfo[] props = proxy.GetType().GetProperties(); ``` In this point, it is natural to think that `props` has 1 property (string Bar), but it is actually an empty array even though `var bar = proxy.Bar` and `proxy.Bar = ""something""` can be compiled. It looks unnatural. In addition, it limits effectiveness of `DispatchProxy`. For example, when we generate a wrapper which implements `INotifyPropertyChanged` around underlying model object using `DispatchProxy`, we cannot do that because the data binding engine fails to retrieve `PropertyInfo` and then fails to bind object. Other AOP scenario may also be restricted by this issue. So, `DispatchProxyGenerator` should also emit properties and events of specified interface type as well as their accessor methods.

Sometimes the CI tests timeout contacting the Azure test server due to network congestion, so this results in the requests getting cancelled as well by the HttpClient.Timeout property. When Http requests are cancelled in WinHttpHandler, the WinHTTP handle is closed. This cancels any outstanding async operations in WinHTTP. However, the current CancellationTokenRegistration code is closing the handle without first seeing if there is an active operation in flight. ``` c# private async void StartRequest(object obj) { // ... using (state.CancellationToken.Register(s => ((WinHttpRequestState)s).RequestHandle.Dispose(), state)) { do { // ... } while (state.RetryRequest); } ``` Since this cancellation is happening on a different thread from the main StartRequest() logic, it results in in-deterministic behavior. PR #8693 (Fix cancellation of WinHttpHandler response stream reads) has a similar CancellationToken.Register logic but it correctly checks for an active operation. This same logic needs to apply to the StartRequest() operation.

We use HttpClient with default windows credentials authentication. The code works fine with one server, but does not work with another server. In the second case client just receives 401 error and does not start NTLM handshake. The only difference that I spotted was that second server sends two WWW-Authenticate headers (one with basic, another with HTML). When I intercepted the response with Fiddler, and removed ""WWW-Authenticate"" header with basic authorization, everything worked fine, client started NTLM handshake, and finally authorized. ```c# var handler = new HttpClientHandler(); handler.UseDefaultCredentials = true; var client = new HttpClient(handler); HttpResponseMessage response = await client.GetAsync(url); ``` Request/response from second server: ``` GET https://my-server:8081/tfs/DefaultCollection/_apis/projects?api-version=1.0 HTTP/1.1 Connection: Keep-Alive Accept-Encoding: gzip, deflate Host: my-server:8081 HTTP/1.1 401 Unauthorized Content-Type: text/html Server: Microsoft-IIS/8.5 Access-Control-Allow-Origin: * Access-Control-Max-Age: 3600 Access-Control-Allow-Methods: OPTIONS,GET,POST,PATCH,PUT,DELETE Access-Control-Expose-Headers: ActivityId,X-TFS-Session,X-MS-ContinuationToken Access-Control-Allow-Headers: authorization X-FRAME-OPTIONS: SAMEORIGIN Set-Cookie: Tfs-SessionId=XXX; path=/; secure Set-Cookie: Tfs-SessionActive=2016-06-07 20:44:23Z; path=/; secure WWW-Authenticate: Basic realm=""my-server"" WWW-Authenticate: NTLM P3P: CP=""CAO DSP COR ADMa DEV CONo TELo CUR PSA PSD TAI IVDo OUR SAMi BUS DEM NAV STA UNI COM INT PHY ONL FIN PUR LOC CNT"" X-Content-Type-Options: nosniff Date: Tue, 07 Jun 2016 20:44:22 GMT Content-Length: 1293 ``` OS: windows 10 x64, app running on coreclr RC2 " 9237 area-System.IO Discuss adding System.IO.Compression static shortcuts "# Problem I'd like to see some better support for compressing data in different forms quickly. Say you have a string right now - to compress it you have to do something like this: ``` string iWantToCompress = ""thisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokaythisisalongstringokay?""; byte[] bytesToCompress = Encoding.UTF8.GetBytes(iWantToCompress); using (var streamWithCompressed = new MemoryStream()) { using (var compressor = new DeflateStream(streamWithCompressed, CompressionMode.Compress, true)) { compressor.Write(bytesToCompress, 0, bytesToCompress.Length); } byte[] compressed = streamWithCompressed.ToArray(); } ``` # Proposal It would be nice if we could compress or decompress a string more intuitively, like so: ``` byte[] compressed = Deflate.Compress(iWantToCompress); ``` This would be somewhat similar to what we did in FileSystem by having`File.WriteAll*` operations to circumvent the need for a `FileStream`. # Design ### Deflate / Zlib / GZIP Deflate, Zlib, and GZip are all variants of the DEFLATE algorithm. The difference between them is that Deflate does not have a header, while ZLib and GZip have their own distinct headers. We currently support Deflate and GZip via DeflateStream and GZipStream, though there is [an issue for adding Zlib header support](https://github.com/dotnet/corefx/issues/7570). Do we add string support for all three types? If so, how? Some options: - Have one `Compression` static class with methods `Compress` and `Decompress` that take in an optional `HeaderType` enum with values `None`, `ZLib`, and `GZip`. The default would be None. ``` string compressed, decompressed; compressed = Compression.Compress(""stringToCompress"", HeaderType.GZip); compressed = Compression.Compress(""stringToCompress""); // uses Deflate i.e. no header is written decompressed = Compression.Decompress(compressed); // decompression can detect and interpret the header for any of the three DEFLATE types, so specifying it explicitly would override that behavior and force the header to conform to the given type ``` - Have 2-3 static classes `Deflate`, `GZip`, and `ZLib` that contain their own `Compress` and `Decompress` methods. ``` string compressed, decompressed; compressed = GZip.Compress(""stringToCompress""); compressed = Deflate.Compress(""stringToCompress""); decompressed = Deflate.Decompress(compressed); ``` - Add static `Compress` and `Decompress` methods to the existing `DeflateStream` and `GZipStream` classes: ``` string compressed, decompressed; compressed = GZipStream.Compress(""stringToCompress""); compressed = DeflateStream.Compress(""stringToCompress""); decompressed = DeflateStream.Decompress(compressed); ``` ### Parameters There should be three versions of Compress + three versions of Decompress: ``` Compress(string stringToCompress); Compress(string stringToCompress, Encoding encoding); Compress(byte[] bytesToCompress); Decompress(string stringToDecompress); Decompress(string stringToDecompress, Encoding encoding); Decompress(byte[] bytesToDecompress); ``` though I could see the value for `stream` equivalents (similar to https://github.com/dotnet/corefx/issues/9222) as well: ``` Compress(Stream streamToCompress); Decompress(Stream streamToCompress); ``` ### Return value Three sensible options: - Return a string with the results of the operation. :-1: - Return a byte[] with the results of the operation - Return a stream that can be read for the results of the operation. - The return type varies based on the parameter type e.g. `Compress(string)` returns a string, `Compress(byte[])` returns a byte[], etc. :-1: # Perf Using these shortcuts would circumvent the need for: - an Underlying stream (e.g. a MemoryStream) to hold the results of the (de)compression. - a DeflateStream/GZipStream object - A Deflater/Inflater object since we would be able to directly hit the ZLibStream SetInput/GetOutput methods because we know the entirety of the item being compressed/decompressed. The downside to this is that the thing being (de)compressed would have to first be entirely in memory, but for a string or byte[] array that isn't an issue. There would be a net memory savings of an object already in memory since we wouldn't need to allocate the internal arrays of a DeflateStream object. # Downsides - Every compress/decompress opens its own ZLibStreamHandle.

This seems like problematic behavior, here's some analysis. On the problematic side, standard async APIs generally throw TaskCanceledException, and SqlClient is doing something different and therefore unexpected. Also, as a result, canceled SqlClient tasks don't have status Canceled, they're Faulted instead. This makes differentiating cancellations from real exceptions more difficult, and the problem is compounded if the SqlClient call is just part of a larger async operation (which again, will be faulted instead of canceled unless some manual specific handling is involved). The argument for the current behavior seems to be that all of SqlClient's server and network errors are raised as SqlException, making it easy to catch all database errors under a single exception type. On the other hand, it seems that cancellation isn't really an error condition as it's been requested by the user and is expected to occur. The TaskCanceledException is simply a mechanism for conveying the cancellation up the stack. For the record, this was originally reported by @mikkeljohnsen for Npgsql in https://github.com/npgsql/npgsql/issues/1146. Whatever is decided here for SqlClient will also be adopted for Npgsql (which currently behaves like SqlClient in this respect). 9248 area-System.Security X509Certificates.Tests.X509FilesystemTests.X509Store_AddAfterDispose This appears to be a test issue.

It's actually not Unix-specific, and rather is a managed implementation on top of System.Net.Sockets and System.Net.Security. I opted to start with a managed implementation as there does not appear to be a universally-adopted native implementation we can utilize. I looked to see if we could just adopt the Mono implementation, but it's based on HttpWebRequest, which in corefx is built on top of HttpClient, which isn't particularly amenable to being used for websockets (and libcurl does not have websockets support). This is passing all of the unit/functional tests, including a few more I added, though I'm fairly confident that there are additional bugs lurking (i.e. I assume there's going to be a bug tail here). I'm opting to check this in as an initial implementation now in hopes that others will be able to help with finding and fixing issues. Along with that, I've spent close to zero time looking at performance; I'm sure there are opportunities to make meaningful improvements, but for now I've opted for simplicity and functionality. There are also two features I didn't implement: proxies and credentials... but it doesn't look like either the WinHttp or WinRT implementations pay attention to those either. cc: @ericeil, @cipop, @davidsh, @bartonjs Fix https://github.com/dotnet/corefx/issues/2486 9260 area-System.Net Update PlatformNotSupportedException message for Socket.Connect on Unix Just the exception message improvement from https://github.com/dotnet/corefx/pull/9218. 9261 area-System.Net Port to release/1.0.0: Update PlatformNotSupportedException message for Socket.Connect on Unix Port https://github.com/dotnet/corefx/pull/9260 to release/1.0.0 9265 area-System.IO AccessViolationException in zlib on CLI Windows build ## Repro steps: - step 1: get a CLI repo - step 1.a: add a remote for github.com/dotnet/cli - step 2: git checkout -b preview2 upstream/rel/1.0.0-preview2 - In case the cli repo moves forward, and somehow that causes the AV to no longer occur: use this sha1: 3c9f8dd99be5918a504f34260f4d6016a086ea99 - step 3: build.cmd -Targets Prepare,Compile - that should succeed - step 4: build.cmd -Targets Prepare,InitPackage,GenerateVersionBadge,GenerateZip,GenerateMsis,GenerateNugetPackages - that will hit the AV ## Notes I’ve uploaded a mini dump with heap: `\\scratch2\scratch\eerhardt\dotnet.dmp` I was able to find clrcompression symbols on the MyGet symbol server: https://dotnet.myget.org/F/dotnet-core/symbols/ Unfortunately, talking with @dagood we are not able to locate the coreclr.pdb file matching the build from yesterday’s CoreCLR build: 1.0.24207.2.

This can happen for redirects, for auth challenges, etc. Handling this has been a challenge due to the way HttpContent is designed. HttpContent provides two modes for accessing the data via Streams: - Push: You call CopyToAsync(Stream, TransportContext) to have the data from the HttpContent copied into the target stream. - Pull: You call ReadAsStreamAsync to get a stream that represents the data in the HttpContent, and you can read from that. The pull model is ideal for libcurl. It allows us to get a stream which we can jump around in if it's seekable, and we can request a new stream if it's not seekable. The push model is challenging, as we're forced to put in plcae an intermediary, a push-pull adapter that let's us effectively read from a type that's trying to write to us. There is however an issue with the pull model. With the push model, StreamContent's CopyToAsync tracks whether the stream has already been accessed, and if it has and if it's non-seekable, trying to call CopyToAsync again throws to alert you that rewinding simply isn't possible. The pull StreamContent's ReadAsStreamAsync, however, does not. This means that if you get a non-seekable stream and you call ReadAsStreamAsync again, you get back the same stream (or, rather, a read-only wrapper around the same stream) that is at the existing position rather than the original position. Then resending that content will end up sending less data than it should have, resulting in failure, just not abruptly. That issue caused us to go down the path of the more challenging push model and trying to use CopyToAsync. However, recently that's been shown to have even worse effects. We don't have the ability to cancel CopyToAsync, which means that if the first copy is still in-flight when we try to seek, we have no choice but to fail, even if the stream is actually seekable, as most are (e.g. memory streams, file streams, etc.) This can happen deterministically in cases where libcurl decides to redirect before it's fully sent the request content, but it's also prone to race conditions even for cases where the request content is fully sent but the copy hasn't been officially marked as complete by the time libcurl tries to redirect. ASP.NET recently began hitting this frequently on some machines in their lab runs. While there's no perfect solution, the best solution is to go with the one that's the simplest code, the fastest code, and the deterministic outcome: the pull model. This commit deletes a whole bunch of code that was there in support of the push model, adds just a bit of code to enable the pull model, and fixes up a couple of tests that were written to expect the push model.

The reason is Exception lack supporting a StackTrace setter property or providing a constructor that can take stack trace as a paramter. The net core supports binary serialization which can serialize and de-serialize the exception objects including the stack trace but this approach is not helping much for the following reasons: - Net core is not promising supporting binary serialization across different net core versions (or with other targets like full framework). - Other serialization engines (e.g. DateContractSerialization) will not benefit from the binary serialization and need to have a way to fully deserialize exception objects. - When binary deserialize exception object which include a stack trace and then throw this de-serialized object, the stack trace after throwing is the one reflect the place where we threw this exception but the original de-serialized stack trace will be lost. The original stack trace will be preserved only in case re-throw previously thrown exception. The following code demonstrate this issue ```C# try { throw new Exception(); } catch (Exception e) { using (MemoryStream ms = new MemoryStream(100)) { BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(ms, e); // reset the stream ms.Position = 0; var excp = (Exception)formatter.Deserialize(ms); Console.WriteLine(excp.StackTrace); // this will show the right original serialized stack try { throw excp; } catch (Exception excp1) { Console.WriteLine(excp1.StackTrace); } // this will show the new stack but the old de-serialized stack will be lost. throw; // the thrown exception will include the original exception stack in “e” object } } ``` To support the scenario, we need to add SourceExceptionStackTrace property to ExceptionDispatchInfo class. The following code demonstrate how ExceptionDispatchInfo can be used to get the exception with the original serialized stack trace and also how to throw the exception with the new stack trace. ```C# ExceptionDispatchInfo edi = ExceptionDispatchInfo.Capture(deserializedException); edi.SourceExceptionStackTrace = originalStackTrace; Exception deserializedExceptionWithOriginalStackTrace = edi.SourceException; edi.Throw(); ``` ## Behavior ExceptionDispatchInfo.SourceExceptionStackTrace The setter of this property will overwrite the current source trace on the source exception. the setter will not affect any other properties in the source exception object. The getter will return the stack trace from the source exception. this can be empty string if there is no stack trace in the source #exception ## Alternative Design We can think in adding a setter for Exception.StackTrace property or expose a method like Exception AddPreservedStack(string stackTrace)) ```C# namespace System { public class Exception : ISerializable, _Exception { public virtual String StackTrace { get; set; } } } ``` I got some feedback from different people that they don't like this option as in the main scenarios nobody should set the stack trace on the exception objects and this option can cause confusion and people misuse it. 9296 area-System.Net Test failure: WebSockets.Client.Tests.SendReceiveTest.SendReceive_PartialMessage_Success (server: wss://corefx-net.cloudapp.net/WebSocket/EchoWebSocket.ashx) http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/release_1.0.0/job/outerloop_windows_nt_debug/lastCompletedBuild/testReport/System.Net.WebSockets.Client.Tests/ClientWebSocketTest/SendReceive_PartialMessage_Success_server__wss___corefx_net_cloudapp_net_WebSocket_EchoWebSocket_ashx_/ ``` MESSAGE: System.Net.Http.WinHttpException : The server returned an invalid or unrecognized response +++++++++++++++++++ STACK TRACE: at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() at System.Net.WebSockets.WinHttpWebSocket.d__30.MoveNext() in d:\j\workspace\outerloop_win---b9d0e81a\src\System.Net.WebSockets.Client\src\System\Net\WebSockets\WinHttpWebSocket.cs:line 458 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter.GetResult() at System.Net.WebSockets.Client.Tests.ClientWebSocketTest.d__16.MoveNext() in d:\j\workspace\outerloop_win---b9d0e81a\src\System.Net.WebSockets.Client\tests\ClientWebSocketTest.cs:line 195 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) ``` 9304 area-System.Net "UDP Socket.ConnectAsync(IPAddress, int) fails with ""An invalid argument was supplied""" "Related to https://github.com/dotnet/corefx/issues/4968...

last few weeks by CI jobs on Windows that hang in System.Net.Http.Functional.Tests, causing the whole job to fail after it eventually times out after two hours. I managed to find a CI server that had a process still alive after having experienced the hang and was able to debug it. The Dispose_DisposingHandlerCancelsActiveOperationsWithoutResponses test is creating three loopback servers and using HttpClient.GetAsync to access each of them. It's then Disposing of the HttpClient to verify that requests which should have been canceled are canceled. The problem is that there's a race condition. We may end up canceling one of the requests before it even gets a chance to connect to the server. As a result, the server remains stuck in an asynchronous accept on it socket, and at the end of the test, we're waiting for all of the servers to shutdown... deadlock. The fix is simple: don't wait for the servers... we don't care about their results, and they'll all be torn down when we exit the inner delegate. Fixes #8926 cc: @davidsh, @ericeil 9325 area-System.Reflection The NetNative implementation of System.Reflection.TypeExtensions does not properly handle generic method overriding. "Consider this class: ``` public abstract class Base { public abstract TResult Foo(Func f); } public sealed class Derived { public override TResult Foo Func f) { return null; } } ``` Calling typeof(Derived).GetMethods() on this is expected to return only Derived.Foo. However, on .NET Native, it returns Base.Foo as well. The bug is in the helper method: AreNamesAndSignaturesEqual(MethodInfo method1, MethodInfo method2) https://github.com/AtsushiKan/corefx/blob/master/src/System.Reflection.TypeExtensions/src/Internal/Reflection/Extensions/NonPortable/MemberPolicies.cs#L63 This method detects overrides by comparing the method name and parameter types. The simple comparison of parameter types is insufficent to detect the override here because the TResult of Base.Foo is considered to be a different type from the TResult of Derived.Foo. We need to do something different here. Probably we'll have to manually compare the types using recursion and define the comparison of generic method parameters as ""compare the position only."" " 9327 area-System.Runtime Fill out AppDomain There are several buckets here, which likely should be broken out. We know .UnhandledException, .CurrentDomain, .GetAssemblies, .GetCurrentThreadId are heavily used in Xamarin/Unity and should be straightforward to add. DefineDynamicAssembly is in the next bucket. True AppDomain support would be a larger challenge. We may distinguish design time support (eg for Unity IDE) vs. bulletproof runtime level support. 9329 area-System.Runtime Fill out GC class Below is what's in Xamarin Android but not in Core.

"While investigating https://github.com/dotnet/coreclr/issues/5558 it was noted that JsonWriterDelegator.WriteDateTimeInDefaultFormat can be sped up considerably for some cases. @mconnew had the following comments: Looking at that code, my guess would be fetching the timezone info from Linux is the expensive operation. This can be easily avoided in the first if-block and this code sped up considerably. This is purely to check an edge case where the regular code won’t catch it and is unlikely to happen but is there for correctness. We can do a cheaper pre-check to reduce the chance of hitting this code. The result from TimeZoneInfo.Local.GetUtcOffset(value) is bounded to +/- 24 hours so we can have some constants which allow us to check if (DateTime.MinValue + 24 hours) < value < (DateTime.MaxValue – 24 hours). If this is true, then we don’t need to do the more expensive check. If it’s false, then we do the full more expensive check. It could be something like this: ``` if (value.Kind != DateTimeKind.Utc) { // lowBound and highBound should be cached statics DateTime lowBound = DateTime.MinValue.AddDays(1.0); DateTime highBound = DateTime.MaxValue.AddDays(-1.0); if(lowBound.CompareTo(value)>0 || highBound.CompareTo(value)<0) { long tickCount = value.Ticks - TimeZoneInfo.Local.GetUtcOffset(value).Ticks; if ((tickCount > DateTime.MaxValue.Ticks) || (tickCount < DateTime.MinValue.Ticks)) { throw XmlObjectSerializer.CreateSerializationException(SR.JsonDateTimeOutOfRange, new ArgumentOutOfRangeException(nameof(value))); } } } ``` In the Local/Unspecified switch block, the code can be rewritten like this: ``` // +""zzzz""; //TimeSpan ts = TimeZone.CurrentTimeZone.GetUtcOffset(value.ToLocalTime()); TimeSpan ts = TimeZoneInfo.Local.GetUtcOffset(value.ToLocalTime()); writer.WriteString(string.Format(CultureInfo.InvariantCulture, ""{0:+00;-00}{1:00;00}"", ts.Hours, ts.Minutes)); break; ``` This results in only one call to writer.WriteString and removes some string concatenations and a bunch of comparisons. " 9343 area-System.Net Use stackalloc for UrlEncode in WebUtility This contains basically the same changes as #8535, except without the branching-related stuff.

" 9369 area-System.Security Add static hash helper methods "Computing a hash code currently requires this code: ``` byte[] hashBytes; using (var hashAlgo = SHA256.Create()) hashBytes = hashAlgo.ComputeHash(bytes); ``` Or the more awkward `HashAlgorithm.Create(""SHA256"")`. This code is alright. It's not the end of the world. But I think it should be slimmer than that: ``` var hashBytes = SHA256.ComputeHash(bytes); ``` Benefits: 1. This is more terse. 2. It's an expression as opposed to a statement. That makes it more composable. It can be a subexpression for example in a LINQ query. 3. No way to forget resource cleanup or mess up code quality otherwise. 4. `SHA256.ComputeHash` can look at it's input size and dynamically pick the fastest implementation. I found the following to be optimal through testing on Windows x64: `estimatedDataLength <= 512 ? new SHA1Managed() : HashAlgorithm.Create(""SHA1"")`. Apparently, using the Windows crypto API has quite some per-hash cost. I request that static helper method be added to the framework. This seems like an attractive case for a community contribution.

It should instead return a custom stream that reads from each part in turn, just as its override of SerializeToStreamAsync doesn't try to store the whole thing into a byte[]/MemoryStream which it could write out but rather writes out each part individually. " 9371 area-System.Net Remove some allocations from unix WebSocket client Some low-hanging fruit. (I have another change that gets rid of many more allocations coming from the networking stack, but I'm seeing an odd behavior I wasn't expecting and am following up on that before submitting it.) - Change how we read message headers. Rather than using a `Task ReadMessageHeaderAsync` method, we now separate the buffering and the reading of the header, saving several allocations. - Removing the WithAbortAsync method. I'd initially added this when it wasn't clear to me that any operation getting canceled is meant to trigger the whole websocket getting aborted. Since that is the behavior, this method is no longer needed and we can do something much simpler, resulting in many fewer allocations per operation.

Any ideas for workarounds will be appreciated :) 9412 area-System.Net More perf improvements for managed WebSocket client on Unix Primary changes: - NetworkStream's Read/WriteAsync simply uses the underlying Socket's Begin/EndReceive/Send methods, wrapped in tasks. While that could be optimized further, we have a more constrained scenario in WebSockets, in that we only support a single read at a time and a single write at a time. As a result, we can create, cache, and reuse a single SocketAsyncEventArgs instance for reading and another for writing, using the socket's Send/ReceiveAsync methods with that cached args instance. This avoids a bunch of per operation allocation. - Due to #4900 (and the behavior that was made to match on Unix), successful socket operations never complete synchronously. This means that code which awaits them typically ends up needing to yield, due to the callbacks being invoked asynchronously, even if the socket operation completed synchronously, which is very likely in the case of a send. Our SendFrameAsync method suffers from this, as it really just delegates to the socket's send method, albeit with a tiny amount of pre- and post-work. The real solution is to make it so that Socket.SendAsync can complete synchronously, after which SendFrameAsync will also typically complete synchronously and generally be allocation-free. Until then, though, since this is a hot path, we can optimize it for the common case to reduce the amount of allocation and general work involved when the socket operation does complete asynchronously. - For chatty cases where each send expects a receive, it's likely that each receive needs to read from the network. This means we end up going through several layers of async methods (ReceiveAsyncPrivate, EnsureBufferContainsHeaderAsync, EnsureBufferContainsAsync), which will all end up yielding and allocating when the read on the network doesn't complete synchronously. Since EnsureBufferContainsHeaderAsync is small and only used from one place, we can avoid all of the allocations associated with it by simply inlining it into its caller (ReceiveAsyncPrivate). Other miscellaneous: - Removed the base class from the internal ManagedWebSocket. It's unnecessary and leads to virtual methods on the instance. More importantly, though, we end up potentially handing out this instance via a Task's AsyncState, and we don't want folks to be able to cast to the base class and call methods without going through the thin ClientWebSocket wrapper. - A bunch of resources weren't being used. I deleted them. - WebSocketReceiveResult had non-readonly backing fields for each of its properties, which had private setters purely to be able to set the properties in the constructor. Now that we're using C# 6, we can simply make these get-only properties, eliminating the setters and allowing the compiler to make the backing fields readonly. - Used nameof in a few more places. Results: I ran a simple test with a local echo server, where I'd repeatedly send a message and receive its echo. As a baseline, with the Windows WinHTTP implementation sending and receiving 20,000 messages, I get the following. Each line is a run of the 20,000 messages, with the first number being the elapsed time and the second number being the number of gen 0 GCs. ``` > corerun WSPerf.exe 28745 20000 1 2.6906097, 5 2.7209642, 5 2.6802832, 5 2.7098154, 5 2.7061351, 6 2.6964876, 5 2.7943476, 5 2.7638309, 5 2.7918148, 5 2.744804, 6 ``` Instead using the managed implementation on Windows, before these changes, I got: ``` > corerun WSPerf.exe 28745 20000 1 3.1177403, 22 3.2149994, 22 2.6798198, 23 2.8078613, 23 2.6670316, 24 2.6744515, 23 2.6619906, 24 2.7596847, 23 2.6485313, 24 2.6559615, 23 ``` After these changes, using the managed implementation on Windows, I get: ``` > corerun WSPerf.exe 28745 20000 1 2.576682, 9 2.6461474, 9 2.5376302, 9 2.5192637, 9 2.5189807, 10 2.5227088, 9 2.5305238, 9 2.5696738, 9 2.5766855, 9 2.5433629, 9 ``` On Linux, I'm using a different local echo server, so the timing numbers aren't directly comparable to the ones on Windows, however before the changes I got: ``` $ ./corerun WSPerf.exe 7681 20000 1 1.6772411, 16 1.2316513, 11 1.1890394, 10 1.7308767, 19 1.1968002, 11 1.5696637, 19 1.5461821, 18 1.2686805, 12 1.1765528, 10 1.124586, 11 ``` and after the changes I got: ``` $ ./corerun WSPerf.exe 7681 20000 1 1.2716779, 5 1.0913687, 5 1.0198689, 5 1.1038351, 4 1.0823826, 4 1.0074977, 4 1.0132344, 5 1.0704005, 4 1.1775556, 6 1.0341026, 6 1.0462667, 4 ``` At this point I'm not planning to do any more proactive work on improving the send/receive performance, as the performance after these changes on Linux looks to be on par with the Windows implementation. There are likely more opportunities which can be addressed individually and reactively, including once #4900 is addressed. There may also be opportunities to improve scenarios other than lots of sending/receiving with the same websocket, e.g. minimizing the overhead associated with creating lots of websockets that each do relatively little work. cc: @ericeil, @bartonjs, @davidsh, @cipop Also fixes #9408 and fixes #9407 9413 area-System.IO System.IO.FileSystem.DriveInfo is missing from .Net Core System.IO.FileSystem.DriveInfo is missing https://github.com/dotnet/corefx/tree/master/src/System.IO.FileSystem/src/System/IO https://dotnet.github.io/api/System.IO.DriveInfo.html 9414 area-System.Net Add test for posting FormUrlEncodedContent with HttpClient https://github.com/dotnet/corefx/issues/9357 cc: @ericeil 9416 area-System.Runtime System.Dynamic.Runtime and System.Runtime tests hanging in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/ubuntu14.04_debug_prtest/2040/consoleText Both the System.Dynamic.Runtime.Tests and the System.Runtime.Tests are hanging.

However, as TcpClient is a thin wrapper for a Socket, code may end up calling Dispose on the TcpClient in order to cancel in-progress async operations, such as ConnectAsync. However, on Unix, ConnectAsync is implemented by creating a new Socket for each address it attempts to connect to, and that Socket isn't stored into the TcpClient until after a connection has been successfully established. As a result, Dispose can't be used to cancel the connect operation, as the Socket won't have been stored yet, and in such cases the Socket won't get disposed of. 9427 area-System.Runtime Several DateTimeOffset tests fail in certain timezones on Linux "e.g. ``` stoub@stoublinux2:~/netcore$ echo ""Europe/Prague"" | sudo tee /etc/timezone Europe/Prague stoub@stoublinux2:~/netcore$ sudo dpkg-reconfigure --frontend noninteractive tzdata Current default time zone: 'Europe/Prague' Local time is now: Tue Jun 14 23:58:46 CEST 2016.

No test logic/code was changed at all. This split helps to keep things a bit tidier, but more importantly, it enables xunit's default parallelization to run tests (from different test classes) concurrently. On my quad-core (which translates into xunit allowing four tests to run concurrently), it reduces the running time of the tests from ~40s to ~10s. Subsequently we might want to move the WebSocketHelper and WebSocketData functions into the new ClientWebSocketTestBase class, but that's orthogonal to this change. The ClientWebSocketTestBase just contains all of the helpers that were in ClientWebSocketTest.cs and that were shared by the various tests. cc: @davidsh, @cipop, @ericeil, @weshaggard 9438 area-System.Security Parameterize System.Security.Cryptography.Rfc2898DeriveBytes for HMAC Currently [System.Security.Cryptography.Rfc2898DeriveBytes](https://github.com/dotnet/corefx/blob/master/src/System.Security.Cryptography.Algorithms/src/System/Security/Cryptography/Rfc2898DeriveBytes.cs) is hardcoded to use HMACSHA1, it would be nice if HMAC could be parameterized.

I've searched around the repo but cannot find anything related, so if this is a dupe feel free to close. ## Problem: Sometimes happens that you have to work with XML files that comes from _untrusted_ sources, and you have to ensure that the file is actually well formed XML. Currently there are [some](http://stackoverflow.com/questions/25791738/determine-whether-a-given-string-is-xml-or-not) not so nice [ways](http://stackoverflow.com/questions/117007/how-best-to-test-the-validity-of-xml-from-a-method) to verify a string is a well formed XML that involves exception handling. None of the suggested ways looks like a clean solution to a quite common problem (at least IMO). Please note also that other [BCL classes](http://referencesource.microsoft.com/#q=Parse) that exposes a `Parse(string source)` method usually also exposes a `bool TryParse(string source, out...)` thus adding a `TryParse` method will make `XDocument` class somewhat more consistent with other BCL classes. ## Suggestion: add the following method `bool TryParse(string text, out XDocument document)` to `XDocument` and `XElement` classes ## Question: Do we need feature parity with `XmlDocument` classes? Actually `XmlDocument` exposes a `LoadXml(string xml)` so we could add a `bool TryLoadXml(string xml, out XmlDocument document)` but I really don't like the name and thus if feature parity isn't a must, I would prefer not adding it. 9446 area-System.Net Flow HttpClient timeouts and cancellation to the response stream Basically this is the same as PR #9102.

This commit resolves that requirement by adding AppContainer support to the Open Windows native build. It also ports some custom CRT code to circumvent undefined API errors and make it WACK-friendly. - The result of this is that a clrcompression built with /p:TargetGroup=netcore50 will have the APPCONTAINER bit set. - When building in netcore50 Release, the imports of the clrcompression will be a limited set of the usual (i.e. non-UWP) imports - this makes the dll pass the WACK supported API check. - The import methods of the Release netcore50 clrcompression are identical to the corresponding clrcompression shipped out of TFS, though the latter imports ""api-ms-win-core*"" whereas the former imports ""kernel32"" and ""ole32"". - This commit will need to be merged alongside a TFS commit to remove clrcompression entirely from the ""PackagesToPublish"" group. - We will also need a commit to the build pipeline to add netcore50 configs to the ""pipelines.corefx.json"" file for the ""CoreFx-Windows-Product-Native-Trusted"" builds. imports of this dll: ``` KERNEL32.dll 180009000 Import Address Table 18000CF30 Import Name Table 0 time date stamp 0 Index of first forwarder reference 214 GetCurrentThreadId 2FA GetTickCount64 117 DisableThreadLibraryCalls 2DD GetSystemTimeAsFileTime 430 QueryPerformanceCounter ole32.dll 180009030 Import Address Table 18000CF60 Import Name Table 0 time date stamp 0 Index of first forwarder reference 7F CoTaskMemFree 7E CoTaskMemAlloc ``` imports of the dll from TFS: ``` api-ms-win-core-profile-l1-1-0.dll 180008038 Import Address Table 18000C188 Import Name Table 0 time date stamp 0 Index of first forwarder reference 0 QueryPerformanceCounter api-ms-win-core-processthreads-l1-1-0.dll 180008028 Import Address Table 18000C178 Import Name Table 0 time date stamp 0 Index of first forwarder reference D GetCurrentThreadId api-ms-win-core-sysinfo-l1-1-0.dll 180008048 Import Address Table 18000C198 Import Name Table 0 time date stamp 0 Index of first forwarder reference A GetSystemTimeAsFileTime E GetTickCount64 api-ms-win-core-libraryloader-l1-1-0.dll 180008018 Import Address Table 18000C168 Import Name Table 0 time date stamp 0 Index of first forwarder reference 0 DisableThreadLibraryCalls api-ms-win-core-com-l1-1-0.dll 180008000 Import Address Table 18000C150 Import Name Table 0 time date stamp 0 Index of first forwarder reference 3E CoTaskMemFree 3D CoTaskMemAlloc ``` This also has the added benefit of upgrading the version of ZLib used in UWP to Zlib-Intel.

I guess my issue / question is how to round trip negative zero in the CLR using the BitConverter.. It gets the Bytes correctly as can be seen here: `System.BitConverter.GetBytes(-0.0)` > {byte[8]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: 0 > [4]: 0 > [5]: 0 > [6]: 0 > [7]: 128 `System.BitConverter.GetBytes(0.0)` > {byte[8]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: 0 > [4]: 0 > [5]: 0 > [6]: 0 > [7]: 0 And I believe that it actually does parse to `-0.0`. However as can be seen by the following statement(s): `-unchecked(-System.BitConverter.Int64BitsToDouble(long.MaxValue + 1))` `unchecked(-System.BitConverter.Int64BitsToDouble(long.MaxValue + 1))` `unchecked(-0.0)` `(0.0 + -0.0)` `System.BitConverter.GetBytes((-1.0 * 0.0))` > {byte[8]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: 0 > [4]: 0 > [5]: 0 > [6]: 0 > [7]: 128 `System.BitConverter.ToDouble(System.BitConverter.GetBytes((-1.0 * 0.0)), 0)`, Evaluates to 0 but as can be seen using the following code: `System.BitConverter.GetBytes(System.BitConverter.ToDouble(System.BitConverter.GetBytes((-1.0 * 0.0)), 0))` You get the same bytes... Yes I am aware there is IEEE 754, which also says that both are equal except in terms of divisions with negative numbers... It also says `−1.0*0.0` == `-0.0` [Wikipedia Signed Zero](https://en.wikipedia.org/wiki/Signed_zero) You cannot evaluate an expression to negative zero because the interpreter always replaces it with absolute 0, however in memory the bytes are actually as they are given by the BitConverter or otherwise which can also be verified as follows: `double d = -0.0;` `*((byte*)(&d) + 7)` Evaluates to `0x80` e.g. `128`. The following code can detect the anomaly: ``` [System.CLSCompliant(false)] public unsafe static bool IsNegativeZero(double* d) { //Check for -0.0 return (*((long*)(d))).Equals(Common.Binary.NegativeZeroBits); } public unsafe static bool IsNegativeZero(ref double d) { //Make a pointer to the pointer, which when dereferenced can access the result. System.IntPtr value = Unsafe.AddressOf(ref d); //Check for -0.0 return (*((long*)((int*)&value))).Equals(Common.Binary.NegativeZeroBits); } ``` This gets even more confusing with Decimals as `new Decimal(0, 0, 0, true, 0).Equals(-0.0m)` evaluates to true. However > System.Decimal.GetBits(new Decimal(0, 0, 0, true, 0)) > {int[4]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: -2147483648 > > System.Decimal.GetBits(-0.0m) > {int[4]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: -2147418112 Since the Decimal type itself is documented this way I find it less intrusive to deal with, however the issue still remains that the value I pass is interpreted as a different but equal value in the cases of Double and Decimal where I do not believe they should be, neither mathematically typing nor obviously with respect to their binary representation. I guess I will go as far as to even propose that '-0.0' Should not be equal to `0.0`, furthermore that the same should also apply to Decimal with respect to the variations of Zero which are possible although I am sure that proposal can be taken elsewhere besides the corefx issues. For instance... `(1 / -0.0) + Double.PositiveInfinity` == `NaN` This indicates the value is actually preserved and calculated as expected to the standard but there is no way to indicate the display of such a value without testing specifically for such and augmenting the results thereof. The only source of information I can find in relation to this topic was from the BCL Team Blog back in 2006: [Here](https://blogs.msdn.microsoft.com/bclteam/2006/10/12/decimal-negative-zero-representation-lakshan-fernando/). It obviates the differences between the decimal representations of negative zero but doesn't touch on the subject for the double type; although I am fairly sure after seeing this the same obviously applies there as well. A more reasonable approach or proposal which would still be compliant to the IEEE standard would be to allow the 'sign' to be given as '+' or '-' via the ToString and not omit it; and also to return the value parsed and not an equivalent representation. Finally, here is a good example of a 'buggy' or weird case in my humble opinion: `System.BitConverter.GetBytes(double.Parse(""-0.0""))` > {byte[8]} > [0]: 0 > [1]: 0 > [2]: 0 > [3]: 0 > [4]: 0 > [5]: 0 > [6]: 0 > [7]: 0 Thanks in advance!

This is spec'd to only work for decimal, but seems to do more than that on both platforms. On Linux, I guess it works well for both hex and octal. On OSX, hex seems to work, but octal only sometimes works. After some experimentation, I think what's going on is that getaddrinfo on OSX tries to parse the address as decimal first, and only if that fails does it try to parse it as octal. So an address like ""010.010.010.010"" will parse as ""10.10.10.10,"" but ""0300.0300.0300.0300,"" since it's not a valid address in decimal, will correctly parse as ""192.192.192.192."" With this change, we use inet_aton to parse IPv4 addresses, instead of getaddrinfo. inet_aton seems to handle octal strings correctly, and is officially documented to do so.

The assumptions made here before this change were probably not valid (xunit doesn't run tests in any particular order), and they certainly aren't valid after this change. We run enough tests in this suite that finalizers are going to end up running, with or without this test case.

This means that I can't use Xunit.Console.NetCore.exe against these versions because the first thing XUnit DOES is to set the console color. I favor turning these NotSupportedExceptions into noops... ideally with some kind of debug output that indicates to the user this happened, in case the behavior is desired so much that they're checking it out under a debugger. Either way, I need some way to run executables that expect to set these colors on such a runtime. 9527 area-System.Net Convert CredentialCache perf tests to xunit.performance These tests were running for a long time, and then ignoring the result. These tests run for ~2 minutes in our functional test passes, even though we're not getting useful data out of them. This change converts the tests to use xunit.performance. This will greatly reduce their runtime when not running as performance tests (we just run one iteration in that case). It will also enable them to produce useful results in our perf lab, where we _do_ have the infrastructure to find regressions in both throughput and GC counts for xunit.performance-based tests. @stephentoub @davidsh @CIPop @justinvp @brianrob 9533 area-System.Net HttpClient on non-Windows does not support Windows authentication "The following code snippet works fine on Windows (.NET Framework), and can authenticate against an IIS web service configured with Windows authentication only.

By capturing packets via Wireshark, no user credentials are sent. (if disable Windows authentication and enable Basic authentication, then it works with 200 status code and user credentials in packets.) So I think the cross platform Windows authentication support is not yet fully implemented. Is there a plan to address this?

The only remaining reason I see for them to not run concurrently is that some of the tests exercise EventSources/DiagnosticSources, which affect the entire process. This PR: - Makes each of those tests run in its own process, so that they don't affect and are unaffected by other tests in the same process - Enables the default xunit parallelism No test logic was changed in this PR, other than moving some tests to their own file and wrapping the body of those tests with RemoveInvoke. As a result, the innerloop execution time drops on my machine from ~60s to ~40s. The majority of the remaining time is spent in the HttpClientHandlerTest class, and simply by splitting up that class, the execution time can easily be dropped to ~15s on a quad core, resulting in xunit's default parallelism level being 4.

We do not have a mapping for this option in `Interop.Sys.SetSockOpt`. It would be nice for this to work, especially if we can get the same behavior as Windows. It looks like there are a couple of options. Supposedly, there exists `IP_DONTFRAG` on some systems (https://www.ibm.com/support/knowledgecenter/ssw_i5_54/apis/ssocko.htm). I'm not sure if any of the systems we support actually have this. Ubuntu/CentOS don't seem to. There is another option, `IP_MTU_DISCOVER` (http://man7.org/linux/man-pages/man7/ip.7.html), which seems to control what we want: ``` Set or receive the Path MTU Discovery setting for a socket. When enabled, Linux will perform Path MTU Discovery as defined in RFC 1191 on SOCK_STREAM sockets. For non-SOCK_STREAM sockets, IP_PMTUDISC_DO forces the don't-fragment flag to be set on all outgoing packets. ``` I'm not familiar with the difference between SOCK_STREAM and non-SOCK_STREAM sockets is, or which we use in our implementation. If we use non-SOCK_STREAM sockets, this seems like a good option. For reference, it looks like [mono](https://github.com/mono/mono/blob/91734968b83a0971c041254286cdc903b26564e2/mono/metadata/socket-io.c#L445) uses `IP_DONTFRAGMENT` or `IP_MTU_DISCOVER`, based on which is available. Presumably, `IP_DONTFRAGMENT` is only available on Windows. If we use `IP_MTU_DISCOVER`, we need to set the value to `IP_PMTUDISC_DO`, according to the above manpage. @ericeil , @pgavlin 9657 area-System.IO Add support for 7z/LZMA1/LZMA2 to System.IO.Compression http://7-zip.org/sdk.html 9664 area-System.Globalization Missing creation of StringComparer for other languages "I'm trying to retarget a portable C# library for .Net core 1.0. I used to do something like this to get a string comparer for a different language, once I obtained a CultureInfo object for the language (via a delegate set by the caller): IComparer comparer = (IComparer)StringComparer.Create(cultureInfo, caseInsensitive); .Net Core currently seems to only support it for the current culture via properties like StringComparer.CurrentCulture. Is there a way to get a string comparer for a given language or culture? This is important for an app that uses multiple languages simultaneously, such as an app for language-learning. From a StackOverflow post I made (http://stackoverflow.com/questions/37801425/how-to-create-stringcomparer-for-different-languages-in-net-core?s=1|2.5892) I got this: ""So, you could set Thread.CurrentThread.CurrentCulture to the desired culture, then grab the StringComparer for that culture using StringComparer.CurrentCulture, then set the Thread.CurrentThread.CurrentCulture to the next desired culture, then grab another StringComparer ... etc."" But it seems it could be better. If it's going to be different from the old .Net, how about something even simpler like: public static StringComparer Create(string languageCode) where language code is a language code such as ""en"" or ""en-us"". Thanks. -John " 9665 area-System.Net Fix HttpRequestMessage reuse handling in HttpClientHandler on Unix HttpRequestMessages are meant to be used for a single request. However, that checking is done by HttpClient rather than by HttpClientHandler. As a result, if code bypasses HttpClient, e.g. by using HttpMessageInvoker or by using a custom HttpMessageHandler sitting between the HttpClient and the HttpClientHandler, the same HttpRequestMessage can be used multiple times without an exception being thrown warning of the invalid usage. And on Windows, things happen to work, but with our Unix implementation was never expecting this scenario and doesn't work well with it: - The handler is explicitly disposing of the request content stream rather than leaving that up to the request content's disposal to handle. - The handler is removing the Content-Length header from the request message content, as a simple way to avoid overriding the Content-Length header that libcurl itself may send based on previous configuration. - The handler is using ReadAsStreamAsync to get the request stream to send, but ReadAsStreamAsync caches the returned stream, so if the same request message is reused with the same Content, the stream will have already advanced to the end of the stream, and when the message gets reused, we won't have content to send. This commit fixes that: - We now don't dispose the request content stream. That'll be left up to the request content's disposal. - We now don't remove the ContentLength header from the request message. We instead just check as we're writing out the headers whether the header is Content-Length, skipping it if it is. - We now store the original position of a seekable stream that's provided to us, and at the end of the request, rather than disposing of the stream, we rewind to the original position if it exists. (If the stream isn't seekable, reusing the request message wouldn't be possible anyway.) This last point also fixes another theoretical issue. When libcurl wants to go back to the beginning of the stream (e.g. in a redirect scenario where it needs to rewind), it asks us to seek back to the beginning. We're currently seeking back to the exact position asked for. But the stream may have come in to us already advanced beyond 0, in which case we need to seek back to the requested offset plus that original position rather than just the requested offset. And in doing this, I noticed that we were inadvertently allowing a set of closure/delegate allocations due to inadvertently using some captured state in a place where we were trying to avoid that. I fixed that as well. We were also marking everything complete before we'd cleaned up all resources, which meant that any failures from such cleanup would go unnoticed. I've fixed that to ensure we clean up all state before we officially declare the async operation done.

Please add an overload that chooses a good default value. 1. Almost nobody seems to know what's a good value to pass here. Nobody takes the time to test this. 2. So far I have never seen a practical case where the value mattered. 3. I'm not even sure to what extent the different operating systems use that value. I know for sure that some do not allow certain ranges of values and override. Quoting [MSDN `listen` documentation](https://msdn.microsoft.com/en-us/library/windows/desktop/ms739168%28v=vs.85%29.aspx): > The maximum length of the queue of pending connections. If set to SOMAXCONN, the underlying service provider responsible for socket s will set the backlog to a maximum reasonable value. If set to SOMAXCONN_HINT(N) (where N is a number), the backlog value will be N, adjusted to be within the range (200, 65535). Note that SOMAXCONN_HINT can be used to set the backlog to a larger value than possible with SOMAXCONN. > SOMAXCONN_HINT is only supported by the Microsoft TCP/IP service provider. There is no standard provision to obtain the actual backlog value. I suggest this: ``` void Listen() => Listen(int.MaxValue); ``` Because this is what `TcpListener.Start()` does. Probably, every interesting OS replaces that with ""a maximum reasonable value"". `SOMAXCONN` is `int.MaxValue` anyway. This seems to trigger the dynamic backlog feature of Windows server OS'es. Note, that `TcpListener.Start(int backlog)` does different argument validation than `Socket.Listen(int backlog)` does. Might be worth investigating and unifying. But that's not what this ticket is about. Surveying what .NET internal code passes: 1. FTP uses `1` for it's active channel. Seems unsafe since a spurious connect (port scan) could kill the connection. 2. WCF uses `if (OSEnvironmentHelper.IsApplicationTargeting45) return (12 * OSEnvironmentHelper.ProcessorCount); else return 10;`. Seems like they made a mistake here and fixed it. `10` clearly is not an appropriate value for a webservice with unknown load profile. I think the new computation is not good, either. They should just pass `int.MaxValue`. I suggest marking this issue as available for community contribution. " 9688 area-System.Text Compat work for Regex As far as I can tell, after commit 4d40e9e there is nothing left to do here. We have the same surface area as Desktop/Xamarin. Please reactivate if this is not the case. 9697 area-System.Net Add Task-based async methods to Socket The Socket class is fully capable of async IO but `Task`-returning methods are missing. I find myself pulling in the same set of helper extensions each time I use async sockets. Since sockets are a primary use case for async IO I'd find this API addition extremely useful. Note, that the async methods on `NetworkStream` are not enough because we need async support for things like `Connect` as well. 9698 area-System.Net Add reliable timeouts to socket operations Socket operations do not support timeouts sufficiently in the following cases: 1. All async operations do not respect the configured timeout. 2. `Connect` cannot be made to observe a timeout. I think there is no timeout for `Accept` either but that's usually an operation that is never supposed to time out. The workarounds usually are quite nasty. For (1) people build their own (tedious and often flawed) timeouts. For (2) people often use an event plus an async IO. In case the timeout fires they close the socket. (This actually triggers [this unavoidable race condition resulting in an access violation!](https://github.com/dotnet/corefx/issues/5749#issuecomment-215597396)) Note the amount of confusion that these problems cause: https://www.google.com/webhp?complete=1&hl=en&gws_rd=cr,ssl&ei=#complete=1&hl=en&q=socket+beginreceive+timeout (I sometimes like to point to Google and Stack Overflow to show a nice sample of real-world user complaints. I have opened this ticket because I'm repeatedly facing this issue as well.) I understand that the underlying Winsock (and now Linux) APIs make some of this hard. Since these issues are so widespread I believe it's worth the work to fix this at the managed code level (by implementing the timeouts and aborts in .NET code as opposed to making the native APIs do that). As an open concern for (1) I see the question what happens to an IO that is cancelled at the managed level due to timeout or cancellation but still running at the native level. This can cause data to be discarded. The only clean way to solve this that I could find is to terminate the connection when a read or write ends up being cancelled. In my experience this matches perfectly with real world requirements. In case of a timeout usually the calling code backs out and just wants to shut everything down. To summarize the ticket: Please add timeouts to all possibly blocking socket operations. Related ticket: [Allow the user to cancel anything at will (this is needed in addition to the timeout).](https://github.com/dotnet/corefx/issues/5749).

LZ4 is by far the fastest compression algorithm out there (at the expense of compression ratio that-is). It makes sense to have such an algorithm available on the baseline release. We can also provide our port of our managed LZ4 implementation of the r131 (which includes acceleration) if that makes the official inclusion of an algorithm we heavily rely upon easier. We are still working on the perf front but it is currently faster than the one that we had https://github.com/Corvalius/ravendb/blob/lz4-131/src/Sparrow/Compression/LZ4.cs 9706 area-System.Net Socket.SendFile leaks FileStream in case of error Here's a sketch of the method: ```c# public void SendFile(string fileName, byte[] preBuffer, byte[] postBuffer, TransmitFileOptions flags) { ... FileStream fileStream = null; ... fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read); ... if (fileStream != null) { ExceptionHelper.UnmanagedPermission.Assert(); ... } ... } ``` 1. The `fileStream` can leak if there's an exception. Actually, I can't find the place where the stream is ever closed but this might be an oversight on my part. This is a resource leak and therefore a bug. 2. `new TransmitFileOverlappedAsyncResult(this)` can leak in case anything throws. This class has a finalizer. Probably a minor issue. 3. Another issue is that if `ReuseSocket` is set but not `Disconnect` we in fact disconnect. Is this really intended? The whole design of the enum stinks as well but we're stuck with that. Also, the enum is not validated and directly passed into unmanaged code. Hope this is alright. Disclaimer: I have not tested this. This is from code review only. 9709 area-System.IO Investigate high-level CompressionStream with header detection "## Problem There have been a number of requests coming up lately to add new compression algorithms to System.IO.Compression. This is a great way to expand the usefulness of the library and be more friendly to other platforms that frequently use compression algorithms other than Deflate/GZip/Zip. However, adding those algorithms will likely introduce lots of new, in-depth API that may add too much complexity to the scenarios where the user just wants to compress/decompress something using the defaults. ## Suggestion We should consider whether we want to provide a high-level way of compression without the need for fine-grained construction and setup, possibly by adding API that allow easy choosing of a Compression algorithm . A **major** part of this would be to add header detection to the default decompression stream. This way we can add detailed compression algorithms in their individual classes (e.g. LZMAStream, BZ2Stream, GZipStream) while still providing a simple Compression/Decompression vehicle with plenty of Algorithm choices. ## API 1 - CompressionStream type ``` public enum Compressiontype { Deflate = 0, GZip = 1, ZLib = 2, LZMA = 3 ... } public partial class CompressionStream : System.IO.Stream { public CompressionStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode) { } // default Deflate for CompressionMode.Compress. CompressionMode.Decompress attempts to detect type from header and defaults to Deflate if it can not be determined. public CompressionStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, System.IO.Compression.CompressionType type) { } // no auto-header detection for Decompression. public CompressionStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, bool leaveOpen) { } public CompressionStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, System.IO.Compression.CompressionType type, bool leaveOpen) { } ... } ``` ### Examples ``` using (FileStream fs = File.OpenRead(""existinggzipfile.gz"")) using (CompressionStream compStream = new CompressionStream(fs, CompressionMode.Decompress)) { // compStream defers entirely to GZipStream } using (FileStream fs = File.OpenWrite(""newgzipfile.gz"")) using (CompressionStream compStream = new CompressionStream(fs, CompressionMode.Compress, CompressionType.GZip)) { // compStream defers entirely to GZipStream } ``` ## API 2 - Compression static class ``` public enum Compressiontype { Deflate = 0, GZip = 1, ZLib = 2, LZMA = 3 ... } public partial static class Compression { public static Stream CreateStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode) { } // default Deflate for CompressionMode.Compress. CompressionMode.Decompress attempts to detect type from header and defaults to Deflate if it can not be determined. public static Stream CreateStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, System.IO.Compression.CompressionType type) { } // no auto-header detection for Decompression. public static Stream CreateStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, bool leaveOpen) { } public static Stream CreateStream(System.IO.Stream stream, System.IO.Compression.CompressionMode mode, System.IO.Compression.CompressionType type, bool leaveOpen) { } ... } ``` ### Examples ``` using (FileStream fs = File.OpenRead(""existinggzipfile.gz"")) using (Stream compStream = Compression.CreateStream(fs, CompressionMode.Decompress)) // stream is a GZipStream { ... } using (FileStream fs = File.OpenWrite(""newgzipfile.gz"")) using (Stream compStream = Compression.CreateStream(fs, CompressionMode.Compress, CompressionType.GZip)) // stream is a GZipStream { ... } ``` Somewhat related to https://github.com/dotnet/corefx/issues/9237.

Until we can build against the API sets in the open, we'll have to continue building it internally. https://github.com/dotnet/corefx/pull/9448 is a closed PR and https://github.com/ianhays/corefx/tree/clrcompression_arm is the corresponding branch that contains the changes required to make the build work for UWP whenever we resolve the API set issue. More info copied from #9448: - OneCore based platforms need api-set imports as opposed to kernel32 imports. The binaries produced by CMake use the kernel32 imports. - The kernel32 import issue is present in the non-appcontainer build as well but it is less of an issue there - Until we solve the API sets import issue, we'll need to keep building the UWP-aot native binaries internally - This means that the aot clrcompression is the old zlib that does not contain the zlib-intel changes. - Since it is only the aot clrcompression that still imports the API sets, debug will use the newer clrcompression that imports kernel32. 9715 area-System.Net Adding multi-machine installation scripts and unifying test configuration. - Powershell scripts to create a 3-machine environment with a client, IIS server and Active Directory Domain Controller. - Changing all test projects to use the `Configuration.*.cs` pattern.

area-System.Collections ICollection.CopyTo argument validation is inconsistent or non-existent Posting now after RTM, as suggested once upon a time. The method `ICollection.CopyTo(Array array, int index)` has a multitude of invalid inputs. Here are some examples ### `array.GetLowerBound(0) != 0` Suggested throw type: `ArgumentException` Problem if not checked: `IndexOutOfRangeException` (bug) Compatability impact: minimal (lower bound is very rarely not 0) ### `array.Rank != 1` Suggested throw type: `ArgumentException` Problem if not checked: `IndexOutOfRangeException` (bug) Compatability impact: slight (array could be multidimensional but this is unlikely to be caught) ### `array == null` Suggested throw type: `ArgumentNullException` Problem if not checked: `NullReferenceException` (bug) Compatability impact: medium (null is a common argument passed incorrectly) ### `index < 0` Suggested throw type: `ArgumentOutOfRangeException` Problem if not checked: `IndexOutOfRangeException` (bug) Compatability impact: medium (e.g. letting user type in a custom index and catching IORE) ### `array.Count - index < collection.Count` Suggested throw type: `ArgumentException` Problem if not checked: `IndexOutOfRangeException` (bug) Compatability impact: medium (e.g. letting user type in a custom index and catching IORE) These are all I can think of at the moment. ## Examples Here are some examples that I've encountered in the past.

The majority check for `array == null` and `index < 0`. The builtin `System.Collections.Generic` types have these checks, but many ICollections offer custom `CopyTo` implementations We should discuss the following: - Do the benefits of validating arguments (fixing a buggy implementation) outweigh the potential compat effects? - Should we allow a non-zero lower bound (e.g. like SortedList)? - Should we establish a consistent ordering for argument validation? Should existing argument validation checks be reordered? /cc @stephentoub and @bartonjs who suggested creating a discussion 9728 area-System.Net HttpClientHandler.ServerCertificateCustomValidationCallback blows up on OSX "I just updated my Project to RTM and did testing on Windows and everything worked.

In order to read from a SSE EventSource (which is basically just a HTTP GET that doesn't close immediately), my code currently: 1. Creates a `HttpClient` 2. Sets up a `HttpRequestMessage` and uses it in a `SendAsync()` on the `HttpClient` to get a `HttpResponseMessage` 3. awaits `HttpResponseMessage.Content.ReadAsStreamAsync()` 4. Enters into a loop calling `ReadAsync()` on the `Stream`, which is then fed into a decoder. The issue is that on RHEL 7.2, `await ReadAsync()` blocks (as expected), but with 100% CPU used by the `dotnet` process. This also occurs if the `ReadAsync()` is replaced by the standard blocking `Read()`. To my untrained eye, it appears to be spin waiting or spin locking, or something in that vain. I have tested and confirmed that the issue does not manifest itself on Windows 10 (build 14372) or Ubuntu 14.04. I have attached a small example project that reproduces the issue. It is unfortunately slightly cumbersome to run, since an event source must be hosted for it to read, and I can't find an existing example event source server to point it to.

Today framework libraries still reference mscorlib, so our mscorlib reference assembly still needs to add type forwards for internal types to S.P.Corelib. We should figure out a plan to remove this without breaking backward compat with developing a framework library that we need to run in UWP against an older version of coreclr which doesn't contain S.P.CoreLib Related: #9712 9759 area-System.IO Add Retain to OSX FileSystemWatcher runloop The OSX FileSystemWatcher uses the CoreFoundation RunLoop API to watch for events. There is a rule that CF objects received from getter functions are not guaranteed to exist unless explicitly retained. We were not doing this, so there was a very infrequent potential race condition wherein cancellation raced with completion of the thread that owned the runloop. When completion happened first, OSX disposed the unmanaged CoreFoundation RunLoop object that was unique to the thread, and cancellation attempted to call API on that now-invalid object.

Each test first calls `SetIn` or `SetOut` on a StreamWriter/Reader wrapped around a MemoryStream. This leads to issues like #9767 where basic operations have bugs that are supposedly tested against. For example, we have this test: ``` [Fact] public void Peek() { const string expected = ""ABC""; Test(expected, () => { foreach (char expectedChar in expected) { Assert.Equal(expectedChar, Console.In.Peek()); Assert.Equal(expectedChar, Console.In.Read()); } }); } ``` that _seems_ to be testing exactly what #9767 proved broken. However, in the `Test` helper we call `Console.SetIn(sr)` - where `sr` is a StreamReader around a MemoryStream - before performing the test action. So this test is actually only verifying that `Console.In` roundtrips with `Console.SetIn` and further that a StreamWriter's Peek and Read functions work. TL;DR: We should look for a better way to test the Writer/Reader returned from a non-redirected Console.Out/Console.In.

While adding methods to the existing classes (say, System.IO.Path) is a big usability plus, it is a deployment headache. Example: If we add Path.CreateRelativePath() it would create a dependency on some future version of the various runtimes (say 4.6.3 for desktop) which inhibits writing portable libraries that consume this API that has no lower level runtime dependencies. We could easily create a library that supports standard 1.0 or 1.3 that contains the pieces people are asking for and not need to force them to a newer set of runtimes to consume the functionality. It would also facilitate getting the desired functionality to users faster as we wouldn't have nearly the same level of plumbing overhead. (For Path in particular there are a _lot_ of pending functionality requests.) Initial name ideas: - System.IO.Portable - System.IO.Utility - System.IO.PathExtended If we go with a more generic name we'd have the ability to add other functionality that we are looking to do without exploding the library count too much.

Could someone explain: 1. Why there are only Windows, WinRT and Unix versions (I guess Mac uses the same Console API as Unix but I didn't realize WinRT is totally separate too). 2. Are there any tutorials about how to compile for each platform? [System.Console.csproj](https://github.com/dotnet/corefx/blob/56600ecc3738940219f3c5a886c6bb0afe1f6a75/src/System.Console/src/System.Console.csproj) seems to contain some complicated rules around this. Also it's not an xproj, which is what I was expecting but it does have a project.json file. 3. Any guidance on understanding how ConsolePal is setting colours would help. 9814 area-System.Net Less crap-tastic fix for Unix intermediate certificates.

Since `StringContent` is an `IDisposable`, we should investigate renting a buffer from `ArrayPool.Shared` when initializing the content, and returning it when we dispose. I've made a prototype here: https://github.com/anonpenguin/PooledStringContent/blob/master/src/Pooling.Net.Http/PooledStringContent.cs (Note however, we may want to come up with a scheme for existing code that assumes `StringContent`'s `Dispose` doesn't do any important work and neglects to dispose it, e.g. ``` cs var content = new StringContent(""...""); // no using return await _httpClient.PutAsync(_uri, content).ConfigureAwait(false); ``` In those cases we may want to stop after renting a certain amount of ArrayPools without disposing, and fallback to allocating like we originally did.) cc @benaadams @davidsh " 9834 area-System.Net Avoid a boxing allocation in UriBuilder.ToString `_port` is an int, so adding it to a string means the `string.Conat(object, object)` overload gets called, which in turn means it gets boxed.

I reference this library from a .Net Core console app which targets net461, and the latter has System.Net.Http **v4.0.0.0** in GAC.

Also, in project references (in solution explorer) System.Net.Http **v4.0.0** is shown. This looks pretty confusing, since I expect that once I referenced NETStandard.Library and target netstandard, I should not care about such versions consistency, since .NET Platform Standard docs claim that netstandard 1.4 is supported by net461 and higher, and netstandard 1.3 is supported by net46 and higher.

The two Windows appmodels are very much like different OSes because of there are different APIs available and things have to be generally done differently in number of places. I believe that the most common pattern has been to use `.Win32.cs` vs. `.WinRT.cs` to provide different implementations. `System.IO.FileSystem` or `System.Console` are good examples. 2. JIT vs. full AOT. I do not actually see any good examples. `System.Linq.Expressions` or data contract serialization where this difference is most prelevant are configured via ifdefs, not via alternative file includes. 3. Different surface of System.Private.CoreLib between CoreCLR and CoreRT/.NET Native. The common pattern for this is `.CoreCLR.cs` vs. `.netcore50.cs` or `.netcore50aot.cs`.

Even if the response header is considered non-conformant with RFC7231, the value is returned as-is as received on the wire. In .NET Core, HttpWebRequest/HttpWebResponse is implemented as a wrapper around HttpClient. HttpClient has a strongly-typed model for headers. The current implementation of HttpWebResponse.ContentType was trying to use the strongly typed header from HttpClient. In cases where the header was malformed, it was returning empty string. This was a difference in behavior from .NET Framework. The fix is to use TryGetValues() to retrieve the raw response header value for the 'Content-Type' header. This will result in compatible behavior with .NET Framework.

Also, I think it's confusing that [the default for `TestNugetRuntimeId` is `win7-x64`](https://github.com/dotnet/buildtools/blob/acf2600/src/Microsoft.DotNet.Build.Tasks/PackageFiles/publishtest.targets#L18), even on Linux. Should it be changed to detect the OS? The same applies to `OSGroup` and `TargetOS`. 9893 area-System.Net SSLStream does not clear InternalBuffer after read SSLStream is vulnerable to memory dump attacks. When working with sensitive data, a programmer has no way to clear the internal buffer of SslStreamInternal after data has been read. And as long as a new packet does not arrive the data will be there indefinitely. SslStream should provide a mechanism to clear the internal buffer or SslStreamInternal should clear InternalBuffer either during every call to DecrementInternalBufferCount or after data is BlockCopy-ed from InternalBuffer to buffer in ProcessRead. 9894 area-System.Xml [dev/xml] Intermittent failures in random System.Xml.XmlDocument tests related to attributes Some threading issue in XmlDoc tests.

There are two easily hit issues with this: 1. On Unix, the ConnectAsync operation doesn't publish the actual Socket on which a connection was made until after the connection is established, as it needs to use temporary sockets to try each potential target address, and publishing it before connecting could end up publishing a Socket that won't end up being the actual one used. As such, if a Dispose occurs during the ConnectAsync operation, it won't end up disposing the socket being used to make the connection, such that the connection won't be canceled. 2. On all platforms, Dispose nulls out the client socket field. When the connection then subsequently completes, it hits a NullReferenceException while trying to dereference that field. This commit addresses both issues: a. When the client is disposed, on Unix we cancel a CancellationTokenSource, and each Socket we create is registered with that source to dispose the socket. That way, we dispose of each socket even if it hasn't been published onto the instance yet. b. We grab the Socket from the field and check for null prior to dereferencing it. cc: @cipop, @ericeil, @davidsh Fixes #9423 9958 area-Infrastructure Support to run selected tests in run-test.sh Add --test-dir option to run selected tests only.

In .NET Core 1.0 the incremental part was moved to a new type and the ICryptoTransform declaration was removed. Presumably requires bug-for-bug compat with Framework, and lots of bug-verifying tests. The other two are required for incremental hash mainly. Or derived types as a secondary thing. 9984 area-System.Security Port System.Security.Cryptography.RijndaelManaged, limited to AES This type is getting significant use. `T:System.Security.Cryptography.RijndaelManaged` We should bring it back as functional, but to make it just wrap Aes.Create(), and fail for any Rijndael settings which are not AES settings (since it looks like our Rijndael implementation restricted it to 128/192/256-bit keys already that really just means use a fixed block size). And make it be [EditorBrowsable(Never)] so IntelliSense never suggests it to someone (and we’ll hide it in a different contract/implementation assembly so it only gets picked up by the mscorlib forwarder anyways). Existing code may be copying extraordinarily stale samples which are merely recommending Rijndael-as-AES over DES/3DES. But, since no one used the Rijndael type directly, and it defines no new members, the compat shim RijndaelManaged should directly extend SymmetricAlgorithm. So pretty much every member just defers to the Aes.Create() object, with the possible exception of BlockSize: ``` public int BlockSize { get { return _aes.BlockSize; } set { // Values which were legal in .NET Framework RijndaelManaged but not .NET Core’s shim type if (value == 192 || value == 256) throw new PlatformNotSupportedException(some resource string saying raw Rijndael is not supported); // Any other invalid block size will get the normal “invalid block size” exception. _aes.BlockSize = value; } } ``` (Or, don’t special case it, and let it just throw the invalid block size exception; but that might be bad form) 9985 area-System.Net WebSocket.CloseAsync can throw when WebSocket.CloseOutputAsync has been previously called on Unix If a client calls WebSocket.CloseOutputAsync on an open WebSocket, a Close frame is sent and the WebSocket transitions into the CloseSent state. If it's then desired to wait until the response Close frame is received, for example to check the response status code that the server sends, a call to WebSocket.CloseAsync can then be made. This is necessary as otherwise the alternative is to poll the WebSocket status property until the state changes. This is also codified as CloseAsync is valid to call when the state is CloseSent. If the Close frame sent by the server is received and processed before the state check in WebSocket.CloseAsync is executed, the state will be Closed and CloseAsync will throw (only allowed states when calling CloseAsync are Open, CloseSent and CloseReceived).

For example the tests [for each collection type](https://github.com/dotnet/corefx/blob/master/src/System.Collections/tests/Generic/HashSet/HashSet.Generic.cs) contains code related to generating the seed/explicitly saying what kinds of type parameters to test. This makes it very hard to add tests for new kinds of types. There is also a lot of `protected abstract` / `override` which makes the code hard to read without jumping back and forth between files, and things like [this](https://github.com/dotnet/corefx/blob/master/src/Common/tests/System/Collections/IGenericSharedAPI.Tests.cs#L50-L55) are not typesafe and reduce readability, since the collection is passed as an argument to the method instead of the method being called on it (e.g. `Count(collection)` vs `collection.Count()`).

Scenario: A client logs into a web app using windows credentials. The web app in turn impersonates that user to make outgoing HttpClient requests also using windows credentials. Expected: The outgoing HttpClient request should made using the impersonated user's credentials. Actual: The outgoing HttpClient request is made using the web apps default credentials. The scenario works fine when running Asp.Net Core 1.0 on .NET 4.6, it only fails on .NET Core. In both the IIS and WebListener scenarios the WindowsIdentity is constructed from an existing handle from a native API: https://github.com/aspnet/IISIntegration/blob/ed85f504d8da633202b3fec5fdf11e8d6153d447/src/Microsoft.AspNetCore.Server.IISIntegration/IISMiddleware.cs#L112. Since this works with .NET 4.6 apps we assume the original handle is valid and something is wrong inside WindowsIdentity or HttpClient. HttpClient does work with impersonated WindowsIdentities created locally (http://stackoverflow.com/questions/7710538/impersonate-with-username-and-password).

The .NET Framework does not have an API to do that. Look at what lengths people have gone to to solve this problem for them: [How do you convert Byte Array to Hexadecimal String, and vice versa?](http://stackoverflow.com/questions/311165/how-do-you-convert-byte-array-to-hexadecimal-string-and-vice-versa) Many of those solutions are somehow bad (e.g. slow or broken or not validating). `BitConverter.ToString(byte[])` generates strings of a practically useless format: `BitConverter.ToString(new byte[] { 0x00, 0x01, 0xAA, 0xFF })` => `00-01-AA-FF`. I don't understand how this decision was made. This seems to be a special solution for some specific purpose (debug output?). Using this API requires `Replace(str, ""-"", """")` which is ugly and slow. Also, this API is not discoverable because it does not have ""hex"" in it's name. I propose adding an API that does the following: - Supports char[] and string - Supports specifying the output buffer to support zero-allocation scenarios - Supports upper- and lowercase - Fast (probably, this means working in-place using unsafe code) - Validates input - _No_ support for any kind of hex prefix (such as ""0x""), whitespace or digit separator (such as ""-"" or ""\n""). This is out of scope. The use case for char[] in- and outputs is low-allocation scenarios. The API could look like this: ```c# static class HexConvert { byte[] ToBytes(string input, int start, int count, HexFormat hexFormat); void ToBytes(string input, int start, int count, ArraySegment outputBuffer, HexFormat hexFormat); //Repeat the same for ArraySegment as input string ToString(ArraySegment bytes); char[] ToChars(ArraySegment bytes); void ToChars(ArraySegment bytes, ArraySegment outputBuffer); //Plus obvious convenience overloads int HexDigitToInteger(char val); //0-9A-F => 0-15. char IntegerToHexDigit(int value, HexFormat hexFormat); //0-15 => 0-9A-F } [Flags] enum HexFormat { UseDefaults = 0, Lowercase = 1 } //extensible ``` A possible extension would be to support `Stream` and `IEnumerable` as sources and destinations. I would consider this out of scope. I feel that converting hexadecimal strings is an important and frequent enough thing that this should be supported well. Of course, a ""light"" version of this proposal is also feasible (just support for string and byte[] with no user-provided output buffer). Not sure if anyone wants/needs lowercase hex, I don't but others might. This seems cheap enough to implement. Testing should be easily automatable. I don't see any particular usability problems. This is suitable for community contribution. " 10021 area-System.Security Possible unnecessary Padding Oracle problems with UniversalCryptoDecryptor.cs I noticed a manual padding implementation in here while I was helping someone debug some code. I'm no crypto expert, but I noticed variable timing on the padding verification, and possibly on the BlockCopy (depending on implementation) is it just a memcpy? Does this open you up to a padding oracle attack? You mention that the platform (I'm assuming BCrypt, doesn't support padding in CBC mode for you), but it does. All you have to do is turn padding on on your last call to BCryptEncrypt and BCryptDecrypt.

To test this, I ran the System.Net.Http tests with the CoreCLR ThreadPool configured to limit itself to a single thread, and to trigger a breakpoint whenever that thread was tied up for a long time: ``` set COMPlus_ThreadPool_ForceMinWorkerThreads=1 set COMPlus_ThreadPool_ForceMaxWorkerThreads=1 set COMPlus_ThreadPool_DebugBreakOnWorkerStarvation=1 ``` The breakpoint was triggered pretty consistently for the tests which use `DelegateStream`, due to that type's default of providing synchronous `Read` and `Write` methods in terms of the caller-supplied async methods; by blocking the current thread until the async I/O completes, we potentially require _another_ ThreadPool thread, which may not be available soon, if ever. This change forces callers to prove synchronous implementations if they've provided async methods, and updates the callers to do so. After this, I have been unable to find any additional ThreadPool starvation issues in these tests. Unfortunately this does not appear to have fixed the problem I was looking at, as I still saw occasional ""a task was canceled"" errors. But maybe it's a good change to make anyway. :smile: @stephentoub @CIPop @davidsh " 10045 area-System.Net Adding server code.

This action is ignoring any potential setting where the headers passed into the client explicitly requested the header to be disabled. For example, something like: ``` c# var httpClient = new HttpClient(); httpClient.DefaultRequestHeaders.ExpectContinue = false; var response = await httpClient.PostAsync(""http://www.example.com"", new ByteArrayContent(new byte[16384])); ``` will result in an Expect header despite the default header setting. This issue could likely be resolved by adding a block of code almost identical to the TransferEncodingChunked header handling in CurlHandler.EasyRequest.cs, line 618 or so.

Especially in a full suite, the same vector(s) might be easily reference by multiple consumers without having to keep a reference of the object they are in generically. can we have additional matrix methods, that are rotate( axis1, axis2, angle) where axis1 and 2 are enumerations for 'forward', 'right' and 'up' or whatever native direction your matrices are? enum { forward, right, left, back[ward], up, down }; where you can specify a direction normal from the matrix and rotate that towards another vector, with a given angle. ( Another solution would be to propose the rules of the JIT and allow adding/extending classes in System.Numerics.Vectors from 3rd party places instead of also requiring optimizations only get considered if the code is in a specifically named DLL; since this does seem to be a 1-off ) In real physics you rarely would apply exactly on a singular axis. It's only convenient in navigating virtual spaces from current input devices... --- More specifically I have a RotateRelative( x, y, z ) method that internally has a tick counter that goes from 0 to 5 for the 6 combinations of roll, pitch and yaw... or rotation about primary axis... This calls a more general function that does `rotate( x_axis, /*to*/ y_axis, angle )` to roll left(or right depending on direction of your axis I guess, or -angle which is just a float) rotate pitch up (pulling back on a airplane yoke)... `rotate( y_axis, z_axis, angle )` /\* rotates pitch down in a positive direction. */ These are simply sin(angle),cos(angle) applied to 2 lines of the matrix.

The 3 cubes above the bottom 6 are single rotation references for directionality... It turns 90 degress and then pauses. Mode 2 is the same as Mode 1 really except slightly faster; so the divergences appear sooner... Mode 1 - the lower 6 are slow motion, as if rotated sequentailly 90 degrees in each of it's directions; in the various combinartions. THe three rotations happen then a pause showing completed doing 90 degrees each way. Mode2 - always applies the rotations in the same order but in smaller steps; some of these are faster than the ideal (top left) and some are slower.... I'm not sure what the reason exactly is for the combinations of three that are the same. Mode 3 the lower 6 cubes are based on building a quaternion using roll pitch yaw... multiplying in order (if text is yaw, pitch, roll... the multiplication is ( ( yaw \* pitch ) \* roll ) . This is saved as a target vector, and then a slerp is used between initial position and the computed target... so especially with larger angles applied; the resulting computation is not the same... demonstrating quaternions to have similar problems... and ideally should also be muxed though an iteration of applied ordering. 10061 area-System.Data SqlConnection's BeginTransaction is slow in .net core 1.0 (up to 250ms) This code is very slow compared to the full .Net Framework (under 1ms), is this expected behavior? _con is SqlConnection and _con_trans is SqlTransaction ``` try { _con.Open(); _con_trans = _con.BeginTransaction(IsolationLevel.ReadCommitted); } catch { _con_trans = null; _con.Close(); throw; } ``` 10062 area-System.Globalization Compat work for Cultures (Globalization) (for Windows) "This work to port the missing APIs from the classes: CultureInfo DateTimeFormatInfo NumberFormatInfo RegionInfo DigitShapes CharUnicodeInfo StringInfo TextInfo You can get the list of the APIs we need to expose from @danmosemsft list https://microsoft.sharepoint.com/teams/netfx/corefx/_layouts/15/WopiFrame.aspx?sourcedoc=%7b79FEE733-9D22-44F8-9BD9-536FF8DF621E%7d&file=android.to.core.component2.xlsx&action=default Please double check the list to make sure we covered all missing APIs.

" 10093 area-System.Runtime Proposal: LegacyAttribute "# The Problem A good thing about the .NET Core 1.0 surface area is that it made it clear what classes/methods were considered obsolete because for the most part, they just didn't exist. With the larger surface area planned for v2 a lot of this missing functionality is being brought back purely for compatibility reasons. How does a developer get informed that a given API is no longer recommended for use? `ObsoleteAttribute` is the heavy handed version of this which says ""You should stop using this immediately, it will be removed in a future version"". There needs to be an ""Info"" level version of this for things that are _considered_ to be obsolete but it's not appropriate to mark it is such. `[EditorBrowsable(EditorBrowsableState.Never)]` assists when writing new code but doesn't help someone identify usages in existing code. If I am using something that is no longer recommended I want to know about, and I would like my IDE to be able to tell me. Marking up libraries with a `LegacyAttribute` would be the first step to having that metadata. # Solution ``` c# [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Enum | AttributeTargets.Interface | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Event | AttributeTargets.Delegate, Inherited = false)] public sealed class LegacyAttribute : Attribute { public LegacyAttribute() public LegacyAttribute(string message) public string Message { get; } } ``` **Semantic Meanings** ""This exists for backwards compatibility. Nothing to see here. Move along"" ""This will work for as long as you need it but we recommend you use something else"" # Examples TimeZone can't be marked obsolete https://github.com/dotnet/corefx/issues/10074 Analyzers need metadata https://github.com/DotNetAnalyzers/Proposals/issues/37 Legacy collections can't be marked obsolete https://github.com/dotnet/corefx/issues/370 (It's common for Java developers to use ArrayList on .net, how do we educate that's not recommended anymore?)

" 10103 area-System.Net Fix two WebSocket issues on Unix This fixes two issues in our managed ClientWebSocket implementation, both of which stemmed from a misunderstanding on my part of how things were supposed to work (or not work): - I thought that if the WebSocket was already in a CloseSent state and then received a close frame that it should transition to Closed. Instead, it's supposed to transition to CloseReceived. Similarly, I thought a WebSocket that was already in a CloseReceived state and then sent a close frame was supposed to transition to Closed. Instead, it's supposed to transition to CloseSent. The WebSocket is only supposed to transition to Closed when the connection is closed, e.g. as part of CloseAsync after a close frame has been both sent and received. - I thought that ReceiveAsync could only be used concurrently with a SendAsync. Turns out we need to support it being used concurrently with a Close{Output}Async. This commit fixes both.

The foreach construct is useful because of the optimizations which are allowed by such as well as the ability to be notified of new changes when they occur. This requires using a `try` and `catch` paradigm which can require more stack space inter alia. I propose that the private member which indicates the version of the `Array` be exposed such that caller would be allowed to observe this property without the use of reflection and without the use of stack preservation.

Look at the #4995 issue for best understanding why I ask for it. Best regards. 10154 area-System.Net Accept HttpContent on any request method Overloads are needed to support HttpContent on methods like GetAsync. The HTTP specification does not prohibit body-level content on any of the method types. They may not be commonly used but I am aware of REST services that require complex body content in GET requests (in one case, it describes a variety of search parameters). 10155 area-Serialization Mismatched behavior for verify the KnownType with Desktop version When serialize a object with unknown type, if the serializer contains a DataContractResolver, it will end up with SerializationException. However, no exception thrown from Desktop Version. This is because, in core version, it always verify knowtype if there's resolver. In the code: System.Private.DataContractSerialization\src\System\Runtime\Serialization\XmlObjectSerializerWriteContext.cs Core Version, which always return true when there's resolver : ``` c# protected virtual bool WriteTypeInfo(XmlWriterDelegator writer, DataContract contract, DataContract declaredContract) { if (XmlObjectSerializer.IsContractDeclared(contract, declaredContract)) { return false; } bool hasResolver = DataContractResolver != null; if (hasResolver) { WriteResolvedTypeInfo(writer, contract.UnderlyingType, declaredContract.UnderlyingType); } else { WriteTypeInfo(writer, contract.Name, contract.Namespace); } return hasResolver; } ``` Desktop Version, which always return false. ``` c# protected virtual bool WriteTypeInfo(XmlWriterDelegator writer, DataContract contract, DataContract declaredContract) { if (!XmlObjectSerializer.IsContractDeclared(contract, declaredContract)) { if (DataContractResolver == null) { WriteTypeInfo(writer, contract.Name, contract.Namespace); return true; } else { WriteResolvedTypeInfo(writer, contract.OriginalUnderlyingType, declaredContract.OriginalUnderlyingType); return false; } } return false; } ``` 10156 area-System.Net Use Loopback server for HttpClient testing. Today, we use http://corefx-net.cloudapp.net/ as an endpoint for much of the HttpClient testing. We've slowly been moving towards using a loopback server that gives back fixed HTTP responses to remove this dependency, (since it's one of the main places we see intermittent network issues that cause spurious test failures) but the set of testing we do against this is currently limited because the loopback server doesn't really understand HTTP so it can't do sophisticated actions based on requests. It should be possible to take the existing implementation of http://corefx-net.cloudapp.net/ and port it to run on ASP.NET Core 1.0. Once we've done that, we could use Kestrel locally to host a loop-back server that binds to a random port as part of setting up the HttpClient tests. This server could live for the lifetime of the dependent tests and then be shut down. There are a few steps to take here: - [ ] Port existing server to ASP.NET Core 1.0 (In progress, @ellismg is working on this) - [ ] Move server from above to be hosted within the tests themselves. - [ ] Figure out how to handle HTTPS HTTPS is interesting, because we need need a valid certificate for the server or we need to configure how we validate the remote certificate, which we only support on Windows and Unix when using an openssl based libcurl (not the case on CentOS, OSX and perhaps others). 10157 area-System.Threading Provide API to understand how many allocations have happened "As discussed in https://github.com/dotnet/coreclr/issues/6275 we would like an API to expose how many bytes were allocated since the beginning of a thread's life time. What about an API like this: ``` C# namespace System { public static class GC { public long GetAllocatedBytesForCurrentThread(); } } ``` The usage could like this: ``` C# [Fact] public void EnsureAllocations() { var allocationsBefore = GC.GetAllocatedBytesForCurrentThread(); var str = ""{'Items':["" + string.Join("","", Enumerable.Range(0, 3000).Select(i => ""{}"")) + ""]}""; var jObject = JObject.Parse(str); var allocationsAfter = Thread.GetAllocatedBytesForCurrentThread(); var allocations = allocationsAfter - allocationsBefore; const long MaximumBytesAllowed = 200 * 1024; Assert.LowerOrEqual(allocations, MaximumBytesAllowed); } ``` Questions: - Can/should this method track bytes per native OS thread or for the logical call context? - Does this track memory across async boundaries? Should it? @Maoni0 ### Updates - Based on @vancem's [concerns](https://github.com/dotnet/corefx/issues/10157#issuecomment-236678904) we've decided not to add `GetAllocatedBytesForThread(int managedThreadId)`. " 10165 area-System.Net Refactor ManagedWebSocket out of ClientWebSocket on Unix On Unix we use a managed implementation of WebSocket as the backing for ClientWebSocket. We'd like to be able to share this same implementation with ASP.NET so that we have a single implementation of the protocol across client and server. This change refactors out that support to make it more shareable. I made a few tweaks to the ClientWebSocket code shared across platforms. While we typically like to have argument validation be in the shared code, I moved the (minimal) argument validation into each of the Windows and managed-specific implementations of the PAL, so that the ManagedWebSocket implementation would perform that validation. I also added support for masking on the server (the current implementation assumed that all sent messages should be masked and all received messages should not be, but a server needs the opposite), though that isn't tested, so we may have some issues to fix there subsequently. I believe ASP.NET should be able to share just the ManagedWebSocket.cs and WebSocketValidate.cs files, plus define a handful of members on an SR type. If this is too complicated to manage well, I can try to simplify it further. cc: @anurse, @Tratcher, @ericeil, @davidsh, @cipop, @davidfowl 10172 area-Meta Question: Multi-Target for NetStandard 2.0 and .NET 4.5 ? Hello! A couple of weeks ago, there was an announcement that most of the BCL will get ported to .NET Core, which is plain awesome. E.g. I should then be able to enable most of my extensive framework library (> 100 projects) for .NET Core. Now, for the question: These features will be delivered when targeting NetStandard 2.0, but I will still have a requirement to support .NET 4.5 in several of my libraries (granted, just 10-15 libraries, but still). Will it be possible to target .NET 4.5 and NetStandard 2.0 with the same build artifact, i.e. without needing to build twice? Before NetStandard, I could do this by adding multiple platform identifiers in my nuget path.

This issue is to track the debt we have for them. related: #10181 10335 area-Meta Remove boilerplate from test projects We should create some larger supports clauses to help reduce boiler-plate in our test projects. EG: `coreFx.Test.net46` should include tuples not just for net46, but also for net461, net462, etc. This is always the correct thing to do. We should also create some convenience supports clauses that allow tests to say they should apply to all the frameworks that support a particular netstandard version. EG: coreFx.Test.netstandard1.3 should include TFM/RID tuples for net46, netcore50, and netcoreap1.0 (as well as the future versions as stated above). This allows a test that can run everywhere to have minimal boilerplate in the project.json. Only if a test needs to hand-select frameworks does it need to use the more framework-granular clauses as mentioned above. We should also have some simple docs that explain the purpose of frameworks and supports in our test project.json's. /cc @ianhays 10338 area-Meta "Microsoft.NETCore.UniversalWindowsPlatform is missing some packages after ""exclude"": ""compile"" updates" "We updated all packages to hide their implementation dependencies with ""exclude"": ""compile"". We did this because implementation dependencies change regularly and aren't seen as part of the compatibility contract of a package. To ensure that folks don't rely on our packages for their implementation dependencies we use `""exclude"": ""compile""` in the packages.

Since Windows 8 (WinRT) a new design principle of Microsoft is “fast and fluid”. But in the full .NET Framework no class is available to virtualize the loading of data. There should be for all UI technologies from Microsoft (WPF, UWA, Xamarin.Forms, ASP.NET) a simple built-in way to load data by page (paging). There are some community projects that have addressed this issue, but I think that Microsoft should provide a uniform solution. - [Virtualizing Observable Collection (Andrew Whiddett, Alpha Chi Technology)](https://alphachitech.wordpress.com/2015/01/31/virtualizing-observable-collection/), [NuGet](https://www.nuget.org/packages/VirtualizingObservableCollection), [GitHub](https://github.com/anagram4wander/VirtualizingObservableCollection) - [WPF: Data Virtualization (Paul McClean)](http://www.codeproject.com/Articles/34405/WPF-Data-Virtualization) - [WPF Data Virtualization (DevZest)](https://datavirtualization.codeplex.com/) - [AsyncVirtualizingCollection (Bea Stollnitz)](http://web.archive.org/web/20111201001632/http://bea.stollnitz.com/blog/?p=378) 10455 area-System.Runtime Add an additional overload to `Marshal.Copy` **Issue:** When writing interop code, it may be desirable to copy memory from one location to another. However, there is currently no managed API for doing so. As such, the user must manually implement such a function, which can be error prone and cannot take advantage of certain optimization techniques (such as using SIMD registers to copy aligned 16-byte blocks). **Workaround:** Use `Buffer.MemoryCopy` which is non-optimal for a few reasons (see https://github.com/dotnet/corefx/issues/10455#issuecomment-236372132), manually implement an API for marshalling memory, or `DllImport` the `memcpy` function from the C Runtime (this is non optimal as it does not necessarily exist in the same library on each platform). **Request:** An additional overload to `Marshal.Copy` should be provided in the form of `public static void Copy(IntPtr source, IntPtr destination, int length)`. This would ideally end up as a call to `memcpy` behind the scenes. 10457 area-System.Runtime Operators should be exposed for `System.IntPtr` and `System.UIntPtr` **Issue:** The CLR supports a set of operators for the `System.IntPtr` and `System.UIntPtr` types (`native int`). These operators can be seen in `III.1.5` of the Command Language Infrastructure specification. However, these operators are not supported by some languages (such as C#). **Workaround:** Either directly emit IL or write non-optimal code that does not directly translate to the appropriate IL instructions. **Request::** A set of 'friendly operators' should be provided for languages that do not support the full set of operators for `System.IntPtr` and `System.UIntPtr`. These operators are: `Add`, `Divide`, `Multiply`, `Remainder`, `Subtract`, `Negate`, `Equals`, `Compare`, `And`, `Not`, `Or`, `XOr`, `ShiftLeft`, `ShiftRight`. 10466 area-System.Linq Avoid triggering lazy allocations of argument collections in LambdaCompiler In various places, the `LambdaCompiler` does access properties like `IndexerExpression.Arguments`, potentially causing the nodes to self-mutate to produce a lazily allocated `ReadOnlyCollection`. We can likely avoid this in many places. In addition, various code paths allocate dynamically growing `List` objects, even though the number of elements can be known upfront. We can reduce this. 10470 area-System.Linq Compiled Lambda Expressions and UWP Is it correct that compiled lambda expressions on UWP aren't really compiled and are instead interpreted? If so does that mean that on UWP and other AOT platforms like Xamarin/Unity with no support for IL emit it is faster to use MemberInfo and ConstructorInfo? Related: https://github.com/JamesNK/Newtonsoft.Json/issues/968 --- If normal reflection is faster on AOT platforms I would like to know is if there is a way at runtime to discover that IL emit isn't supported? A way to discover this capability at runtime will allow libraries to use compiled lambda expressions to boost on platforms it is available, and to fallback to traditional reflection on platforms where it isn't, while still using a single netstandard assembly. 10478 area-System.Threading Add x64 LOCK CMPXCHG16b (coreclr) ## 128 bit/16 byte Interlocked.CompareExchange with structs ### Use cases - Lock free algorithms using tagged state reference rather than GC (for ABA problem) - Atomic update for 16 byte structs on heap (e.g. `Span`, `Vector4`) ### Availability - Always - Windows 8.1 x64 (Required) - Always - Windows 10 x64 (Required) - Always - OSX/MacOS (Intel) - Usually - Linux x64 - Usually - Windows 7 x64 ### Performance - Not fast, but generally less than double a 8 byte LOCK CMPXCHG ### Issues - No 32 bit available (I believe?) - Not available on some early AMD x64 (pre-2006) - Alternative may not be available for ARM and other CPUs - Data needs to be 16 byte aligned ### Questions Seems a bit heavyweight for general case of 16 byte struct copy (e.g. `Vector4`) Would prevent tearing when coherence is required, though slow (e.g. [heap based `Span`](https://github.com/dotnet/coreclr/issues/5851#issuecomment-228599829)) But both tagged state reference and `Span` would have a similar data format, so also contain references. | 64 bits | 64 bits | | --- | --- | | Reference | Data | Would require the heap struct to have an alignment (16 bytes), would need to be [first class structs](https://github.com/dotnet/coreclr/blob/master/Documentation/design-docs/first-class-structs.md) for passing.

So additionally it would be good to have a type Atomic which mirrors the C++ 11 atomic type, adds some .NET magic and can fallback to locks when the data width is not supported on the platform. ### Proposed Api Interface, struct, class, extenstions (and some reference manipulation types) ``` csharp namespace System.Threading.Atomics { public interface IAtomic where T : IEquatable { T Read();

} ``` Or an entirely new type that hadn't previously supported atomic updates, with new operations ``` csharp public static Decimal Multiply(this TAtomic atom, Decimal value) where TAtomic : IAtomic { return atom.Transform((current, m) => current * m, value); } ``` When the struct was 16 bytes `_data` would need to be 16 byte aligned to allow lock free use with `LOCK CMPXCHG16b` where available. Might be easier to enforce alignment than with https://github.com/dotnet/corefx/issues/10478? `VersionedReference` and `FlaggedReference` should be 16 byte aligned in `Atomic` (don't need to be outside), as should `TaggedReference` when the struct is <= 16 bytes. 10487 area-System.ComponentModel GuidConverter.ConvertTo throwing exception to convert valid guid string to Guid object.

Not surprising, a big source of allocations is for `object[]` instances passed to `Invoke` methods in reflection. I'm opening this issue to track some possible improvements in this area. Instructions for `Call`, `New`, etc. seem to allocate an empty `object[]` in case there are no arguments, in order to call the `Invoke` method through reflection. We should be able to avoid these allocations here and pass `Array.Empty()` instead. ~~In addition, we may be able to reduce `object[]` allocations in general, given that reflection also copies the argument array in `CheckArguments`, by caching a limited set of reusable `object[]` buffers for small lengths. I don't think `System.Buffers` fits the bill unfortunately, because it will hand out buffers of a minimum size or larger. Unless reflection would be able to operate on `ArraySegment` to 'trim' the view over a rented array, we'd have to keep our own cache. An obvious question is the trade-off between allocating arrays and the (synchronization) cost of renting them from a pool.~~ 10523 area-System.Data Question about database connection I know MS Sql Server is only running in Windows platform.

They are kind of an annoyance to parse manually (and do it properly.) It would be great if the System.Net.Http library offered built-ins for these. 10526 area-System.ComponentModel Consider merging DisplayFormatAttribute into DisplayAttribute We use `DisplayFormatAttribute` heavily to provide annotations which can be consumed by several kind of controls like grids, text contents, etc. The issue with this attribute is that it's not localizable. In one of .NET's earlier versions the _legacy_ `DisplayName`, `Description`, and `Category` attributes have been merged into the new `DisplayAttribute`, so that they can be nicely localized. However, at that point for some reason, the `DisplayFormatAttribute` had been kept separately. It would be important to merge it into `DisplayAttribute` too, because it has at least two fields which are important to localize: ``` public string DataFormatString { get; set; } public string NullDisplayText { get; set; } ``` These should definitely be part of `DisplayAttribute` I think. 10527 area-System.ComponentModel Allow EditableAttribute for classes I have a scenario where I need to specify `EditableAttribute` on a class, instead of applying it separately to every property.

An attempt to create it using a carbon copy from other projects with such a `Performance` project ran into some issues on referencing the `pkg`, so I'm adding an issue to track progress on this. If anyone with more awareness of the benchmark infrastructure could help out here, that'd be useful too. 10563 area-Infrastructure Needs to refactor code for option 'restrict-proj' in run-test.sh "run-test.sh accepts a parameter, regex for an option restrict-proj. The regex is used as $TestSelection in run_test(). ``` bash # $1 is the path to the test folder run_test() { testProject=`basename $1` # Check for project restrictions if [[ ! $testProject =~ $TestSelection ]]; then echo ""Skipping $testProject"" exit 0 fi // ... } ``` Above function, run_test() executes after run_all_tests(). ``` bash # $1 is the name of the platform folder (e.g Unix.AnyCPU.Debug) run_all_tests() { for testFolder in ""$CoreFxTests/$1/""* do run_test $testFolder & pids=""$pids $!"" numberOfProcesses=$(($numberOfProcesses+1)) if [ ""$numberOfProcesses"" -ge $maxProcesses ]; then wait_on_pids ""$pids"" numberOfProcesses=0 pids="""" fi done # Wait on the last processes wait_on_pids ""$pids"" pids="""" } ``` I think it's better that moving $TestSelection in run_test() into run_all_tests() and then using it with command 'find'.

" 10566 area-System.Net Dotnet core's sockets don't seem to have access to the SocketAPMExtensions I've made [a github repo](https://github.com/johnnymo87/socket-apm-extensions) to demo my issue. Copying the readme here ... According to my understanding of the conversation in [this issue](https://github.com/dotnet/corefx/issues/2936), dotnet core supports APM methods for sockets, such as `BeginConnect` and `EndConnect`. I believe the support for it appears [here](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Net/Sockets/SocketAPMExtensions.cs) in the source code. I must be doing something wrong, however, because I am unable to access those methods in my code.

On POSIX (which, really, Windows should hurry up and start implementing… grr…), it should: 1. If `backup` is not `null`: 1. `unlink(backup)`, ignoring `ENOENT` error but for other failures throw `IOException`. 2. `link(destination, backup)` and if that fails throw `IOException`. 2. If `backup` is `null` 1. `stat(destination)`, if `ENOENT` throw `IOException`. 3. `rename(source, destination)` and if that fails throw `IOException`. This guarantees that the file at `destination` never ceases to exist even with program termination or power failure. The `backup` feature is best effort on POSIX any existing file is not guaranteed to be restored if the later steps fail. However, if `backup` is specified but does not exist, failure at a later step will not cause any data loss—it will just leave behind a second link to `destination` at the path `backup`. And a future call/retry would just wipe away and recreate this `backup`.

This way we're actually testing the latest SNI version that we're publishing. I also updated the ExternalPackages props to be correct for clrcompression and updated them for the new SNI package. @jhendrixMSFT @chcosta 10597 area-System.Data System.Data.SqlClient depends on the stable SNI package The beta meta SNI package (runtime.native.system.data.sqlclient.sni) depends directly on the stable RID specific SNI packages, when it should depend on Microsoft.Net.Core.Targets like runtime.native.system.io.compression does. This is an issue because System.Data.SqlClient depends on the stable version of the SNI package which is fixed to depend on the stable SNI package: ``` System.Data.SqlClient/latest => runtime.native.system.data.sqlclient.sni/stable => runtime.win7-x86.system.data.sqlclient.sni/stable System.Data.SqlClient/latest => runtime.native.system.data.sqlclient.sni/stable => runtime.win7-x64.system.data.sqlclient.sni/stable ``` So this means we're not testing the latest/prerelease/beta versions of SNI anywhere. This has the potential to cause some confusion or late-testing errors when we snap to the next stable version and we're all of a sudden testing any changes made to SNI since the previous stable version. It'd be nice to have SNI follow the native asset pattern set by the other packages (HTTP, compression, Security) to avoid potential confusion, so it would look like this instead: ``` System.Data.SqlClient/latest => runtime.native.system.data.sqlclient.sni/stable => Microsoft.Netcore.Targets/stable => (restoration uses the latest targets package) => runtime.win7-x86.system.data.sqlclient.sni/latest System.Data.SqlClient/latest => runtime.native.system.data.sqlclient.sni/stable => Microsoft.Netcore.Targets/stable => (restoration ues the latest targets package) => runtime.win7-x64.system.data.sqlclient.sni/latest System.Data.SqlClient/latest => runtime.native.system.data.sqlclient.sni/stable => Microsoft.Netcore.Targets/stable => (restoration uses the latest targets package) => runtime.win10-arm64.system.data.sqlclient.sni/latest ``` I've worked around this for now by explicitly adding the latest SNI version to the project.json for the SqlClient tests: https://github.com/dotnet/corefx/pull/10596, but that's not an ideal solution since the product is still using the stable SNI and we're just overwriting it when testing. @ericstj @weshaggard @mellinoe 10600 area-System.Net System.Net.* Tests require special compilation rules because of System.Net.Internals System.Net.\* Tests utilizes an internal namespace, System.Net.Internals.

This leads to validation silently not taking place on client-side, there's neither an error during compilation of the C# code nor during execution in browser (took me some minutes to figure out what was going on…). It would be nice if there was either some kind of warning, or—even nicer but a lot harder to manage—an automatic transformation step that makes C# side regexes work even when they're used in the definition for the client side validation, so you don't have to keep the regex around in 2 flavors (for client and server side validation). *as per https://docs.asp.net/en/latest/tutorials/first-mvc-app/validation.html " 10610 area-Infrastructure Cannot Build For FreeBSD "While trying to follow the directions here: https://github.com/dotnet/coreclr/blob/master/Documentation/building/freebsd-instructions.md I keep getting the same error Building .NET Core on FreeBSD 10.1 and this is the second install of FreeBSD I've seen this with so far.

When the message gets encrypted and decrypted, the output message is the same with the exception of one byte that gets inserted. Behaviors observed - The inserted byte is always the same and in the same position if the test is run several times. It seems that the introduced is a 0x0D in place of the 154th byte. (The inserted byte could also be 0xD0, but it's unlikely as it wouldn't be byte aligned, but given that the insertion looks like ...760A9AE94... to ...760D0A9AE94... it is hard to determine which of the two was inserted and as I haven't been able to reproduce the error with any other message there's no easy way of determining it). This hints it could be a padding error. - If trailing bytes are deleted from the message, the insertion is kept consistent, both the byte inserted and the offset. - If bytes are deleted from the start of the sequence, the inserted byte is consistent but it shifts back by the number of bytes deleted from the message. - It seems like it has nothing to do with block or length as a random message of the same length could be encrypted and decrypted correctly. - There are tests trying to encrypt longer and shorted messages so it continues to seem unlikely to be a length/alignment problem.

I'm new to .NET Core stuff, but from what I've read it seems like I should only need to reference the newest possible `System.Linq.Expressions` package, e.g. `4.1.1-beta-24412-03`, which should contain the fix. But doing that changes nothing; my app still crashes. So I looked at the contents of the package with ildasm, and it appears that the `netcore50` version doesn't contain the fix (looking at the contents of `System.Linq.Expressions.Interpreter.LightCompiler::CompileUnaryExpression`), while the `netstandard1.6` version does, and UWP is using the former. Is this expected, and if so, how can I get a fixed version of that package in an UWP app? 10749 area-System.Security Add time-constant equals and other utility methods to System.Security In applications sensitive to side-channel timing attacks, a constant time equality check can be used instead of a normal short-circuiting String.Equals (or similar for byte[], etc.). This is functionality often duplicated by application developers, copied and pasted from StackOverflow and what not. This is easy to subtly get wrong, and probably belongs somewhere in System.Security. We can see an example of this already implemented in an internal .NET class: [Microsoft.AspNetCore.Cryptography.Internal](https://github.com/aspnet/DataProtection/blob/dev/src/Microsoft.AspNetCore.Cryptography.Internal/CryptoUtil.cs#L90), but this isn't really the best place for it 😃 --- Edited by @bartonjs to match what was approved: ```csharp namespace System.Security.Cryptography { // new type in System.Security.Cryptography.Primitives.dll public static class CryptographicOperations { public static bool FixedTimeEquals(ReadOnlySpan left, ReadOnlySpan right); public static void ZeroMemory(Span span); } // Existing type in System.Security.Cryptography.Algorithms.dll public abstract class RandomNumberGenerator { public static void Fill(Span data); } } ``` 10752 area-System.Collections Collection and ObservableCollection do not support ranges "Let's keep the final speclet at the top for easier search # Speclet (Updated 9/23/2016) ## Scope Modernize `Collection` and `ObservableCollection` by allowing them to handle operations against multiple items simultaneously. ## Rationale The `ObservableCollection` is a critical collection when it comes to XAML-based development, though it can also be useful when building API client libraries as well. Because it implements `INotifyPropertyChanged` and `INotifyCollectionChanged`, nearly every XAML app in existence uses some form of this collection to bind a set of objects against UI. However, this class has some shortcomings. Namely, it cannot currently handle adding or removing multiple objects in a single call. Because of that, it also cannot manipulate the collection in such a way that the `PropertyChanged` events are raised at the very end of the operation. Consider the following situation: - You have a XAML app that accesses an API. - That API call returns 25 objects that need to be bound to the UI. - In order to get the data displayed into the UI, you likely have to cycle through the results, and add them one at a time to the ObservableCollection. - This has the side-effect of firing the `CollectionChanged` event 25 times. If you are also using that event to do other processing on incoming items, then those events are firing 25 times too. This can get very expensive, very quickly. - Additionally, that event will have `ChangedItems` Lists that will only ever have 0 or 1 objects in them. That is... not ideal. This behavior is unnecessary, especially considering that `NotifyCollectionChangedEventArgs` already has the components necessary to handle firing the event once for multiple items, but that capability is presently not being used at all. Implementing this properly would allow for better performance in these types of apps, and would negate the need for the plethora of replacements out there ([here](http://blog.ddeysel.com/technicals/introducing-the-awesome-observable-collection/), [here](http://tliangnet.blogspot.com/2013/04/observablecollection-performance-issue.html), and [here](https://github.com/Windows-XAML/Template10/blob/master/Template10%20%28Library%29/Utils/IEnumerableUtils.cs#L34-L45), for example). ## Usage Given the above scenario as an example, usage would look like this pseudocode: ``` cs var observable = new ObservableCollection(); var client = new HttpClient(); var result = client.GetStringAsync(""http://someapi.com/someobject""); var results = JsonConvert.DeserializeObject(result); observable.AddRange(results); ``` ## Implementation This is not the complete implementation, because other `*Range` functionality would need to be implemented as well. You can see the start of this work in PR #10751 ``` cs // Adds a range to the end of the collection. // Raises CollectionChanged (NotifyCollectionChangedAction.Add) public void AddRange(IEnumerable collection) // Inserts a range // Raises CollectionChanged (NotifyCollectionChangedAction.Add) public void InsertRange(int index, IEnumerable collection); // Removes a range. // Raises CollectionChanged (NotifyCollectionChangedAction.Remove) public void RemoveRange(int index, int count); // Will allow to replace a range with fewer, equal, or more items. // Raises CollectionChanged (NotifyCollectionChangedAction.Replace) public void ReplaceRange(int index, int count, IEnumerable collection); // Removes any item that matches the search criteria. // Raises CollectionChanged (NotifyCollectionChangedAction.Remove) // RWM: Excluded for now, will see if possible to add back in after implementation and testing. // public int RemoveAll(Predicate match); ``` ## Obstacles Doing this properly, and having the methods intuitively named, could potentially have the side effect of breaking existing classes that inherit from `ObservableCollection` to solve this problem. A good way to test this would be to make the change, compile something like Template10 against this new assembly, and see if it breaks. --- So the `ObservableCollection` is one of the cornerstones of software development, not just in Windows, but on the web. One issue that comes up constantly is that, while the `OnCollectionChanged` event has a structure and constructors that support signaling the change for multiple items being added, the `ObservableCollection` does not have a method to support this. If you look at the web as an example, Knockout has a way to be able to add multiple items to the collection, but not signal the change until the very end. The `ObservableCollection` needs the same functionality, but does not have it. If you look at other extension methods to solve this problem, like the one in [Template10](https://github.com/Windows-XAML/Template10/blob/master/Template10%20%28Library%29/Utils/IEnumerableUtils.cs#L34-L45), they let you add multiple items, but do not solve the signaling problem. That's because the `ObservableCollection.InsertItem()` method overrides `Collection.InsertItem()`, and all of the other methods are private. So the only way to fix this properly is in the `ObservableCollection` itself. I'm proposing an ""AddRange"" function that accepts an existing collection as input, optionally clears the collection before adding, and then throws the `OnCollectionChanging` event AFTER all the objects have been added. I have already implemented this in a PR #10751 so you can see what the implementation would look like. I look forward to your feedback. Thanks!

And such output is not always text (e.g., imagine a series of openssl commands). Unfortunately, the System.Diagnostic.Process class _assumes_ that output and input is textual. Such an assumption violates Linux conventions. 10800 area-System.Data Use ConditionalFact in Manual tests of SqlClient Based on the comment at https://github.com/dotnet/corefx/pull/10742#issuecomment-239888047 `ConditionalFact` can be used to conditionally execute the Xunit This issue is being opened to track the change. 10804 area-Infrastructure Enable full test runs for netcoreapp1.1 Enable full test runs for netcoreapp1.1 in master.

Suppose I have an enum type defined by `FlagsAttribute`and has an enum value that is outside the limit of the enum type. I would then have a way to easily remove the flags that are not defined. This can be useful if I eg get an enum value from an external API, and all the flags are not defined in the internal enum type. I would then want clear the unsupported flags. Alternative solution proposals: **Alternative 1** ``` C# [ComVisibleAttribute(true)] public static object ToObject( Type, int, bool=false ) ``` If you set the the new boolena value to `true`, unknown flags is removed. This should only be valid for enum types that are defined with `FlagsAttribute`, or else the function throw a exception. (By the way, why are not `ToObject`generic to avoid having to cast like #692 ?) **Alternative 2** ``` C# public int BitMask { get; } ``` It returns a bit mask that can be used like this: `var cleanedEnumValue = myEnumValue & myEnumValue.BitMask;` **Alternative 3** ``` C# public object RemoveUndefinedFlags { get; } ``` It returns a enum where the undefined flags have been masked away. Or if the enum is not defined with `FlagsAttribute`, it throw a exception. 10909 area-System.Net "Test failure: System.Net.Security.Tests.ClientAsyncAuthenticateTest/ClientAsyncAuthenticate_EachClientUnsupportedProtocol_Fail with ""System.IO.IOException""" Opened on behalf of @Jiayili1 The test `System.Net.Security.Tests.ClientAsyncAuthenticateTest/ClientAsyncAuthenticate_EachClientUnsupportedProtocol_Fail` has failed. ``` Assert.Throws() Failure\r Expected: typeof(System.NotSupportedException)\r Actual: typeof(System.IO.IOException): Authentication failed because the remote party has closed the transport stream. ``` Stack Trace: ``` at System.Net.Security.SslState.InternalEndProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.SslState.EndProcessAuthentication(IAsyncResult result) at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Threading.Tasks.TaskTimeoutExtensions.d__0.MoveNext() in D:\A\_work\4\s\src\Common\tests\System\Threading\Tasks\TaskTimeoutExtensions.cs:line 19 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Net.Security.Tests.ClientAsyncAuthenticateTest.d__14.MoveNext() in D:\A\_work\4\s\src\System.Net.Security\tests\FunctionalTests\ClientAsyncAuthenticateTest.cs:line 142 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) ``` Failing configurations: -

There seem to be several methods inside System.Numerics.Vectors.Matrix4x4 that should be removed or placed in a utility library as extension methods. Many `Matrix4x4.Create*` methods impose conventions on the users that they may not be able to accept. For example, Matrix4x4.CreateWorld() seems to negate the passed in forward axis and store it that way. For those using a right-handed x-right, y-forward, z-up coordinate system, this is very annoying for debugging purposes (and incorrect). Similar issues apply to other Create functions and there are several that would never be used (CreateShadow, etc.). This API would be much easier for us to adopt if it was considerably trimmed down to a minimum (required) number of functions and then other methods added as extensions that can _not_ be included so that those that do things differently or don't need them can still get some SIMD benefits under C#. Also in regards to SIMD benefits, Matrix4x4 does not seem to have any. I'm not clear as to why this was not designed to contain 4 Vector4 values, but if it was, it is considerably more likely that _required_ operations such as Vector \* Matrix would see SIMD benefits without having to add more/unneeded intrinsics to the JIT compiler. 10932 area-System.IO Throw specific error messages for unsupported zip Appends the common unsupported compression type to the end of the exception message for an unsupported compression type.

When I reference this library from another project targeting `net462`, I can see in the Visual Studio dependency tree that several references sort of 'drop out' of 'package dependency' mode and into 'framework assembly' mode: - System.Runtime (4.1.0, drops to 4.0.20) - System.Runtime.Extensions (4.1.0, drops to 4.0.10) - System.Reflection (4.1.0, drops to 4.0.10) Now, there is another somewhat similar issue with the current 4.1.0 package for System.Net.Http, where it drops to 4.0.0 and causes problems, but I have been able to work around that by locking the project.json file and deleting the portion that specifies it as a framework assembly. I see no such analog for these other libraries and I can't find anything of note in their .nuspec files. Changing the test library to target as low as `netstandard1.1` yields no desirable effect. Although I would prefer not to mention this sort of thing, a current project I am working on is blocked by this because at runtime it is causing a failure to load the System.Runtime library. I mention this because I want to be clear that it is not a nitpicking issue but rather an actual impediment.

This is undesirable because it's a confusing crash with a ""forbidden"" exception type in BCL code. This should be changed. Example: `foreach(var item in new int[][] { new int[1], null }.SelectMany(x => x)) { }` The safest approach would be to throw an exception that explains that the user has provided an invalid `selector` that does not obey the contract. Additionally, the [documentation](https://msdn.microsoft.com/en-us/library/bb534336%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396) should state the requirement to not return `null`. An alternative approach would be to treat `null` as an empty sequence. I'm not sure which solution is better. Sometimes, an empty sequence would be very convenient. Sometimes this would hide a bug. Also it's unclear that this can be done due to compatibility concerns. I think throwing a different exception type would be safe enough to take the change. " 11030 area-System.Numerics Add generic Math methods for numeric types "## Overview With the addition of System.Numerics.Vector it suddenly became possible to write some generic algorithms that worked for most primitive numeric datatypes. However as soon as you need to work with single elements you are out of luck. I propose a new generic API for scalar datatypes based upon the ideas behind System.Numerics.Vector. Just as for vectors many of the genereic methods could be generated using .tt files such as in https://github.com/dotnet/corefx/blob/master/src/System.Numerics.Vectors/src/System/Numerics/Vector.tt ## API This is an example of how the API could look like. All methods below are taken from the Vector class (https://msdn.microsoft.com/en-us/library/system.numerics.vector(v=vs.111).aspx). **Additional methods** such as those found in System.Math (https://msdn.microsoft.com/en-us/library/system.math.aspx) would be interesting as well. It could also be interesting to add non-generic methods such as `float Round(float x, int digits);` as well All functionlity could be provided in a new nuget package in order to allow out of band releases without conflicts with the current Math type. ```c# public static class Scalar { public static T Abs(T left, T right) where T : struct public static T Add(T left, T right) where T : struct public static T AndNot(T left, T right) where T : struct public static T BitwiseAnd(T left, T right) where T : struct public static T BitwiseOr(T left, T right) where T : struct public static T Divide(T left, T right) where T : struct public static T Max(T left, T right) where T : struct public static T Min(T left, T right) where T : struct public static T Multiply(T left, T right) where T : struct public static T Negate(T left, T right) where T : struct public static T OnesComplement(T left, T right) where T : struct public static T SquareRoot(T left, T right) where T : struct public static T Subtract(T left, T right) where T : struct public static T Xor(T left, T right) where T : struct // Useful methods part of Vector public static T Zero() where T : struct public static T One() where T : struct } ``` The generic requirements for some methods might be changed a bit to allow additional types, such as using providing extra overload such as those suggested in https://github.com/dotnet/corefx/issues/1583. Comparison and equality checking was not included since IComparable<> and IEquatable<> are implemented for the types already, but if it is considered a good idea to be as similar as possible to Vector then the following methods should also be considered ```c# public static bool GreaterThan(T left, T right) where T : struct public static bool GreaterThanOrEqual(T left, T right) where T : struct public static bool LessThan(T left, T right) where T : struct public static bool LessThanOrEqual(T left, T right) where T : struct ``` ### Types to support I propose that all the primitive numeric types including decimal are supported (the same types as Vector<> support but with the addition of decimal). Invoking any method with any other type should result in an NotSupportedException() - Byte - SByte - UInt16 - Int16 - UInt32 - Int32 - UInt64 - Int64 - Single - Double - Decimal (The only difference from Vector) ### Related issues: I found a few issues regarding similar ideas - #1151 is about adding new Math functionality which could be added to the ""Scalar"" type - With corresponding PR in https://github.com/dotnet/coreclr/pull/5492 - #1583 - Add generic overloads to Math.Min and Math.Max - #467 - add Clamp method " 11033 area-System.IO Release these reserved names: COM1-COM9, LPT1-LPT9, CON, AUX, PRN, and NUL Use the `\\?\` prefix to access them internally. 11035 area-System.Runtime Expose serialization primitives on .NET Native Remove ApiCompatBaseline.netcore50aot.txt / ApiCompatBaseline.uap101aot.txt baselined errors once resolved, e.g. that CultureNotFoundException doesn't implement ISerializable in the implementation. - src\System.Globalization\src\ApiCompatBaseline.uap101aot.txt - src\System.Threading.Tasks\src\ApiCompatBaseline.uap101aot.txt - etc. 11036 area-System.Net .NET Core crashes when using HttpClient with HTTP/2 and Client Certificates "**Scenario** We have built an ASP.NET Core service which connects to Apple's HTTP/2-based APNS servers (in order to send push notifications from our ASP.NET Core-based platform to Apple devices). Unfortunately, .NET Core 1.0.0-rtm crashes hard in release mode when opening an HTTP/2 connection using a client certificate. In debug mode, it sometimes behaves better. **Result when running code in release mode (.NET Core 1.0.0-rtm, Ubuntu 16.04 Server)** Hard crash. After about 8 seconds of executing HttpClient.SendAsync(...), .NET Core 1.0.0-rtm crashes hard. Exception handlers do not execute. **Result when running code in debug mode (.NET Core 1.0.0-rtm, Ubuntu 16.04 Desktop, VSCode 1.4.0)** Inconsistent behavior, ranging from long delays to hard crashes. Sometimes .NET Core crashes, and sometimes the HttpClient.SendAsync(...) call times out and throws a catchable exception. And sometimes after a few debug cycles it mostly works, with a delay of around 8 seconds and then a successful response to the initial HTTP/2 request. In the last case, where the HttpClient request does succeed (in debug mode): once the HTTP/2 connection is open, sending additional messages in real-time to APNS servers (re-using the same HttpClient connection) works quickly and seemingly consistently. In our tests to date, the failure only occurs during the initial ""HTTP/2 client using client certificate"" connection attempt. As additional info: if we remove the client certificate from the request, the HTTP/2 secure connection goes through immediately (although APNS of course returns an ""unauthorized...missing certificate (sic)"" text reply). **Repro** 1. Install .NET Core 1.0 on Ubuntu 16.04 LTS 2. Compile libcurl from source to include HTTP/2 support (see next post in thread) 3. Save your APNS development certificate to disk, and fill in its path and password in the sample code. Also fill in your APNS bundle/deviceToken IDs in the sample code. 4. Drop the sample code inside Program.cs Main() and run the sample. 4a. In release mode, the HttpClient.SendAsync(...) line of code will run for about 8 seconds and then .NET Core will crash hard without raising an exception. 4b. In debug mode from VSCode, the HttpClient.SendAsync(...) line of code will exhibit intermittent hard crashes, intermittent exceptions, and/or ~8 second delays with successful connection.

Consider the following code: ``` using System; using System.Security.Cryptography.X509Certificates; namespace ConsoleApplication { public class Program { public static void Main(string[] args) { new X509Certificate2(fileName: ""invalid.cer""); } } } ``` on Windows, the following exception is thrown: ``` Unhandled Exception: Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: The system cannot find the file specified at Internal.Cryptography.Pal.CertificatePal.FromBlobOrFile(Byte[] rawData, String fileName, String password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate..ctor(String fileName, String password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(String fileName) at ConsoleApplication.Program.Main(String[] args) ``` whereas the following exception is thrown on Linux and OS X: ``` nhandled Exception: Interop+Crypto+OpenSslCryptographicException: error:2006D080:BIO routines:BIO_new_file:no such file at Interop.Crypto.CheckValidOpenSslHandle(SafeHandle handle) at Internal.Cryptography.Pal.CertificatePal.FromFile(String fileName, String password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate..ctor(String fileName, String password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(String fileName) at ConsoleApplication.Program.Main(String[] args) ``` As such, this confirms to the MSDN specifications of the `X509Certificate2` constructor because all it says is that a `CryptographicException` should be thrown - which is the case. It seems that the error message contains too much information - I'd argue it should only read ""no such file"" or a user-friendly string, and the underlying OpenSSL error code (2006D080) could go on a different property of the OpenSslCryptographicException class.

When looping through an object's properties to validate them, I can set the context's `MemberName` property appropriately each run through, but any non-successful validation results may return a nonsensical message since the validators use the `DisplayName` property to format the message, and the `DisplayName` property getter caches its return value the first time it is used. In addition to this, the `DisplayName` property cannot be reset as the setter will throw an `ArgumentNullException`. I could envision any of the following approaches to resolve this: - Allow setting `DisplayName` to `null` or `""""` - Set the `_displayName` field to `null` whenever `MemberName`/`_memberName` are changed - Offer a method like `Reset(bool clearItems = true)` to be a bit more explicit " 11045 area-System.Xml XML .Save() method missing option to use filename It seems that System.IO.Stream, System.IO.TextWriter, and System.Xml.XmlWriter are still options, but using string filename has been removed. 11046 area-System.Security X509Certificate2/OpenSSL: Unable to open PKCS#12 files with no password and no MAC "If you have a PKCS#12 file which is not protected with a password, and which does not have a MAC entry, opening the file will work on Windows but fails on Linux and Mac (which use OpenSSL).

A Claim Value can be > **any JSON value**. This is big problem for us while creating a .NET Core app for a large established ecosystem where JWTs have object claims.

The behavior is different from NetFX and the NetFX behavior seems to be the correct one. I've done the following - `git clone corefx` - `init-tools.cmd` - `build.cmd` That builds the repo & the tests pass, so I'm pretty sure the checkout I have is in a consistent state. Next, I - Open `src\System.IO.Compression\System.IO.Compression.sln` with Visual Studio 2015 Update 3 which also has the Windows 10 tools installed. - Set the configuration to `Debug_Windows` - Set `System.IO.Compression.Tests` as the Startup project - Hit F5 to start debugging At this point, the tests load correctly and I can set breakpoints and step through the test project. However, for the `System.IO.Compression.dll` assembly itself, it seems that the test project takes the assembly from a NuGet package rather than the version which was just built by Visual Studio: - In the Modules window, the timestamp for the `System.IO.Comrpession.dll` indicates it was built to days ago - The symobls are not loaded, and when trying to load the symbols, the original path is set to `D:\A\_work\4\s\bin\obj\Windows_NT.AnyCPU.Release\System.IO.Compression\System.IO.Compression.pdb`, which looks like a build server path So, I'm sure I've missed something that caused the test to run against a NuGet package instead of the `System.IO.Compression.dll` which I built locally, but I can't figure out what. Any guidance?

Note that `TrySetFromTask` in https://github.com/dotnet/corefx/blob/d0dc5fc099946adc1035b34a8b1f6042eddb0c75/src/System.Threading.Tasks/src/System/Threading/Tasks/TaskExtensions.CoreCLR.cs has a remark on the possibility for this method to become public. Another place where this would have been useful is in the suggested fix for #7953 . 11091 area-System.Linq Probe for sufficient stack during expression tree compilation recursion When compiling deep expression trees, we run into `StackOverflowException` which terminates the process. There are four recursive algorithms used for compilation/interpretation: - Stack spilling, a custom visitor with recursive method `RewriteExpression` - Variable binding, a classic expression visitor with recursive method `Visit` - Lambda compiler, a custom tree traversal with recursive method `EmitExpression` - Light compiler, a custom tree traversal with recursive methods `CompileExpression[AsVoid]` A repro is compiling a deep expression tree, such as a binary expression: ``` csharp var e = (Expression)Expression.Constant(0); var n = 10000; for (var i = 0; i < n; i++) e = Expression.Add(e, Expression.Constant(1)); var f = Expression.Lambda>(e).Compile(useInterpreter); ``` This fails regardless of the `useInterpreter` flag. There are three possible approaches: - Don't do anything; these trees could be considered rare enough to warrant a change. However, it seems EF has run into this (see #7953 for more info) and the outcome is process termination triggered by a carefully crafted web request (DoS attack potential). It'd still be interesting to see whether the generated EF tree can be flattened. - Trade the `StackOverflowException` for another exception type that can be caught by users, so it doesn't terminate the process. This is similar to what WPF does in e.g. `Control.FindControl` by using `RuntimeHelpers.EnsureSufficientExecutionStack`, or what Roslyn does when it raises compilation error `ERR_InsufficientStack`. - Use the mechanism used to detect an upcoming stack overflow (e.g. by counting levels of recursion or by using `RuntimeHelpers.EnsureSufficientExecutionStack`) and mitigate the issue by borrowing the stack of another thread. This is similar to `TrySetFromResult` in https://github.com/dotnet/corefx/blob/d0dc5fc099946adc1035b34a8b1f6042eddb0c75/src/System.Threading.Tasks/src/System/Threading/Tasks/TaskExtensions.CoreCLR.cs This PR uses the latter approach and hardens the four places where unbounded recursion can lead to stack overflow conditions by using `RuntimeHelpers.EnsureSufficientExecutionStack` and jumping to another thread to continue the computation when this condition is met. Ideally, we'd see the `TryEnsureSufficientExecutionStack` method become public so we can do away with the exception handling logic (see #11090). 11093 area-Infrastructure Remove System.Runtime dependency in System.Runtime.Extensions Use the System.Runtime package once published instead. https://github.com/dotnet/corefx/blob/dev/api/src/System.Runtime.Extensions/ref/System.Runtime.Extensions.csproj#L17 11094 area-Infrastructure Remove reference to live package of System.Runtime.Extensions in System.Runtime.Tests Remove once prerelease gets updated again https://github.com/dotnet/corefx/blob/dev/api/src/System.Runtime/tests/System.Runtime.Tests.csproj#L119 11095 area-System.Net Disable NoSocketsReuseUnicastPortSupport tests Fixes #11088 11096 area-System.Linq ConstantCheck.IsNull can check for DefaultExpression as well Noticed when analyzing some generated IL code for binary expressions performing comparisons against `Expression.Default(type)` where `type` is a reference type or a nullable value type. The `ConstantCheck.IsNull` method does only consider `ConstantExpression` to check for a `null` constant value, though `DefaultExpression` would be worth checking for as well. We have an `IsNullableOrReferenceType` helper method that can be used for this purpose. Note that `ConstantCheck` appears in both the compiler and the interpreter. For platforms that support both, we can reduce code size by moving these utilities into common files (see https://github.com/dotnet/corefx/issues/11097). 11097 area-System.Linq Reduce code duplication in expression compiler and interpreter A good example is the `ConstantCheck` class which seems to occur twice.

Publish package on nuget.org - https://www.nuget.org/packages/System.Net.Http/4.3.1 ----------------------------------------------------------- ## Impact of the change - Breaking changes Here's list of technical breaking changes caused by the proposed solution. It includes workarounds for each. Note that these new behaviors are specific when running on net46 / Desktop. When you run on .NET Core, the behavior is intact. 1. `HttpClientHandler.CheckCertificateRevocationList` (introduced in System.Net.Http 4.1) * New behavior: Throws `PlatformNotSupportedException` * Workaround: Use `ServicePointManager.CheckCertificateRevocationList` instead (impacts the whole AppDomain, not just single `HttpClientHandler` as it did in System.Net.Http 4.1-4.3) 2. `HttpClientHandler.SslProtocols` (introduced in System.Net.Http 4.1) * New behavior: Throws `PlatformNotSupportedException` * Workaround: Use `ServicePointManager.SecurityProtocol` instead (impacts the whole AppDomain, not just single `HttpClientHandler` as it did in System.Net.Http 4.1-4.3) 3. `HttpClientHandler.ServerCertificateCustomValidationCallback` (introduced in System.Net.Http 4.1) * New behavior: Works fine, except that the first parameter of type `HttpRequestMessage` is always `null` * Workaround: Use `ServicePointManager.ServerCertificateValidationCallback` 4. HTTP/2.0 support (introduced in System.Net.Http 4.1) * New behavior: System.Net.Http (for net46 = Desktop) no longer supports HTTP/2.0 protocol on Windows 10. * Workaround: Target System.Net.Http.WinHttpHandler NuGet package instead. * Details: * HTTP/2.0 support is part of the new CoreFx HTTP stack which on Windows is based on WinHTTP. The original HTTP stack in .NET Framework 4.6 did not support HTTP/2.0 protocol. If HTTP/2.0 protocol is needed, there is a separate NuGet package, System.Net.Http.WinHttpHandler which provides a new HttpClient handler. This handler is similar in features to `HttpClientHandler` (the normal default handler for HttpClient) but will support HTTP/2.0 protocol. When using HttpClient on .NET Core runtime, the WinHttpHandler is actually built-in to HttpClientHandler. But on .NET Framework, you need to explicitly use WinHttpHandler. * Regardless of whether you are running using .NET Framework runtime (with WinHttpHandler) or .NET Core runtime using HttpClientHandler (or WinHttpHandler), there are additional requirements in order to get HTTP/2.0 protocol working on Windows: * The client must be running on Windows 10 Anniversary Build (build 14393 or later). * The `HttpRequestMessage.Version` must be explicitly set to 2.0 (the default is normally 1.1). Sample code: ```c# var handler = new WinHttpHandler(); var client = new HttpClient(handler); var request = new HttpRequestMessage(HttpMethod.Get, ""http://www.example.com""); request.Version = new Version(2, 0); HttpResponseMessage response = await client.SendAsync(request); ```" 11105 area-System.Linq Some locals in the expression compiler and interpreter could be avoided See https://github.com/dotnet/corefx/pull/11091 for the full discussion. We have a bunch of places where we have a pattern like: ``` csharp private void CompileBinaryExpression(Expression expr) { var node = (BinaryExpression)expr; ``` We could perform the cast higher up and save a local. 11107 area-System.Security Coreclr crash due to double freeing Openssl handles Coreclr crashes due to a double Dispose of an openssl handle if the openssl function PKCS12_parse (called by Corefx's CryptoNative_Pkcs12Parse) returns false. When Openssl's PKCS12_parse fails, it frees the handles that it allocated into *pkey and *cert. But those output parameters do not get nulled by either Openssl or the corefx PAL shim and so the freed handles become valid managed handles. When those managed handles get disposed it leads to a second call to free on them, crashing coreclr. Repro: In theory it should be possible to write a test that exercises this, but you would need to come up with binary data that passes the initial call to d2i_PKCS12 but then fails in PKCS12_parse. This is beyond my meager time, understanding, and abilities. I encountered this issue when accidentally using a (crippled) version of Openssl that had rc2 support removed (./Configure no-rc2); in that case, PKCS12_parse would fail for all inputs, exposing the issue. Proposed Solution: Add an else block to the success check in CryptoNative_Pkcs12Parse that pushes nullptr into both *pkey and *cert. 11112 area-System.Security Port IsolatedStorage CAS members ```

On OSX/Linux it prints ""Value: 0"". 0 seems like the wrong return value here since it'd indicate success. Mono currently returns -1 on platforms that don't support COM interop, but we're debating what to do on e.g. iOS since we need to add this method there for netstandard compliance: https://bugzilla.xamarin.com/show_bug.cgi?id=43646. The problem is that some code like serilog is using this method (see [Xamarin Forum post](https://forums.xamarin.com/discussion/73925/targeting-netstandard-1-6-on-xamarin-ios-no-marshal-gethrforexception) and [GitHub](https://github.com/search?q=org%3Aserilog+GetHRForException&type=Code)) so throwing PlatformNotSupportedException (which we added for all these Marshal APIs right now on iOS) won't make that code work either which is why I'm thinking about just changing it to -1 as well there. But ideally we'd be consistent with .NET Core :) Any reason why you're returning 0 instead of -1 or some other generic error code? /cc @stephentoub Version: ``` $ dotnet --info .NET Command Line Tools (1.0.0-preview2-003121) Product Information: Version: 1.0.0-preview2-003121 Commit SHA-1 hash: 1e9d529bc5 Runtime Environment: OS Name: Mac OS X OS Version: 10.11 OS Platform: Darwin RID: osx.10.11-x64 ``` " 11151 area-Meta Track implementation assemblies that should be merged At the lowest levels of CoreFx, our implementation assemblies are very fine-grained, making it difficult to do certain implementations. For example, Environment lives in System.Runtime.Extensions.dll, which is at a lower-level than System.IO and System.IO.FileSystem. That means on Unix when we need to read a configuration file in support of Environment.GetFolderPath, we have to do very strange contortions to make it work, e.g. including lots of duplicated code or writing custom I/O implementations, using reflection to find the relevant I/O types in another assembly, etc. This leads to bloat, is fragile, etc. We should look at recombining some of these implementation assemblies. This issue is to help track such dependencies. cc: @weshaggard, @danmosemsft, @ericstj, @KrzysztofCwalina - [ ] System.Runtime.Extensions needs access to file I/O to implement Environment.GetFolderPath on Unix (Directory.CreateDirectory and File.ReadAllLines are used) - [ ] System.Runtime.Extensions needs access to Process to implement Environment.WorkingSet (Process.GetCurrentProcess().WorkingSet64 is used) - [ ] ... 11154 area-System.Runtime Proposal: Support comparisons of IntPtr and UIntPtr ## Rationale Now that #8592 has been approved meaning both of `IntPtr` and `UIntPtr` will implement `IEquatable<>`, it would also make sense for them to implement `IComparable<>` and the comparison operators as well. This will amend this [rather unintuitive situation](http://tryroslyn.azurewebsites.net/#b:master/f:>il/K4Zwlgdg5gBAygTxAFwKYFsDcAoADsAIwBswBjGYCEAQwDNUZSjqQQYBhbAb2xj5nzEyMAG4B7MABMYAWQAUASl78e/NTACSEZAAVkAJxhFUtZDAC8m7Xv0A6AFqp9YnOv5bdBmPrBQAFmaWHjYOTi7KbhHqYLQwcsamMAA83r4BCjBcAL5ROWpRgiTk4lIwAHKKUapuMAQIaABURiaBMBDARESuNXWNqf6t7Z3dkTUwMXEJZik+AxnZudhZQA==), where it is possible to compare 2 raw pointers with `<`, but not 2 IntPtrs. It will also add better support for native math since it will allow two words to be compared without manually calling `ToPointer()` on each of them (and therefore resorting to unsafe code). Finally, implementing `IComparable` means `Array.Sort` on an array of IntPtrs will just work as expected, without having to write your own comparer. ## Proposed API ``` cs namespace System { public struct IntPtr : IEquatable, IComparable { public static bool operator <(IntPtr left, IntPtr right); public static bool operator <=(IntPtr left, IntPtr right); public static bool operator >(IntPtr left, IntPtr right); public static bool operator >=(IntPtr left, IntPtr right); public int CompareTo(IntPtr other); } public struct UIntPtr : IEquatable, IComparable { public static bool operator <(UIntPtr left, UIntPtr right); public static bool operator <=(UIntPtr left, UIntPtr right); public static bool operator >(UIntPtr left, UIntPtr right); public static bool operator >=(UIntPtr left, UIntPtr right); public int CompareTo(UIntPtr other); } } ``` ## Open Questions - Should `IntPtr` have the same semantics as int/long (signed) or `void*` (treated as unsigned?) for comparisons? For example: ``` cs var ptr = new IntPtr(-1); Console.WriteLine(ptr.ToInt64() < IntPtr.Zero.ToInt64()); // True Console.WriteLine(ptr.ToPointer() < IntPtr.Zero.ToPointer()); // False Console.WriteLine(ptr < IntPtr.Zero); // What should this be? ``` After dotnet/coreclr#6855 I'm guessing the better answer is the first one. ## Related issues - #10457 - dotnet/coreclr#963 11155 area-Meta .NET Standard Library vs. .NET Platform Standard vs. NETStandard.Library "There are some [references ](https://docs.microsoft.com/en-us/dotnet/articles/standard/library) that the "".NET Standard Library"" is covered in the `NETStandard.Library` package.

I need to load a dll(a valid .net core dll) that is not part of my project at runtime, I need to do that so I am able to read the types defined in the assembly so I can generate some XML files based on the properties and attributes for that type, in .Net 4.x it's pretty straight forward. Thanks. 11159 area-System.Net Fix WinHttpHandler uri escaping for HTTP requests There is a behavior difference between .NET Framework (Desktop) and CoreFx. Desktop will send some reserved characters (such as square brackets) on the wire as-is without any percent-encoding. CoreFx using WinHttpHandler is doing additional percent-encoding on those characters. This fix changes WinHttpHandler behavior so that it won't do any additional percent-encoding. Whatever encoding System.Uri has done will be transmitted as-is. There is a separate problem where System.Uri itself doesn't percent-encode these characters during normalization. That is due to changes in the .NET Framework 4.5 timeframe (2012) where System.Uri was changed to follow more IRI (RFC 3987) rules. One could argue that was the real problem. But since this behavior is already baked into .NET Framework, the right fix for the below issue is to match Desktop behavior. We will be having a separate discussion/issue to analyze/debate whether System.Uri needs to be changed (or not) in the future. The various URI and HTTP RFCs have ambiguous language in these areas. Fixes #11156 11160 area-System.Reflection No way to get the simple name parts of a TypeRef Namespace without many allocations. "Currently, if you are using MetadataReader and you have a handle to a TypeReference, then the only data exposed is: ``` c# public StringHandle Name { get; } public StringHandle Namespace { get; } public EntityHandle ResolutionScope { get; } ``` If the typeref is for a type in a namespace called ""A.B.C"" This means that if you want the constituent namespace parts (like ""A"", ""B"", ""C""), you first need to allocate the full string and then split it into smaller strings. Contrast this to the TypeDefinition where you can get handles to the NamespaceDefinition and can get just the Name off of it and it's parents. This is an issue in Roslyn because it causes allocations we don't want when we just want to get the namespace pieces (like we do for TypeDefs). A api to expose the individual pieces would be appreciated.

I tried implementing this using async methods, however this library needs to support net451 and netstandard, which both do not support the same async methods. In C previously, I've seen programs that do a non blocking connect() call, and the a poll() call to detect if the socket has finally connected, and timing out after enough poll failures have passed. The code below is a simplified version of what I have ported, and it works perfectly on windows, both with .net 4.5.1 and .net core RTM. The poll call returns false and loops until timeout. However, on linux and mac, the poll call always returns true, even when I can verify there is no socket listening on that port. If I try to call connect after the poll call returns true, I end up getting a ConnectionRefused error code. Is there a specific setting that would need to be called additionally on unix systems to make this work properly, or is this an internal library issue? ``` Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Blocking=false; try { socket.Connect(IPAddress.Loopback, 2222); } catch (SocketException ex) { if (ex.SocketErrorCode == SocketError.WouldBlock || ex.SocketErrorCode == SocketError.InProgress) { while (true) { if (socket.Poll(1000, SelectMode.SelectWrite) { // Socket connected (or should be anyway) return; } else { // Check if timed out here } } } } ``` 11177 area-System.Security Failed assert in pal_symmetric.cpp http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/osx_debug_prtest/3686/consoleText ``` Assertion failed: (algorithm == PAL_AlgorithmAES || operation == PAL_Algorithm3DES), function AppleCryptoNative_CryptorCreate, file /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_debug_prtest/src/Native/Unix/System.Security.Cryptography.Native.Apple/pal_symmetric.cpp, line 54. ``` 11189 area-Infrastructure build.cmd -UpdateInvalidPackageVersions no longer working "Trying to run this command now produces the error: ``` error MSB4057: The target ""UpdateInvalidPackageVersions"" does not exist in the project ``` " 11192 area-System.Net Enhance LoopbackServer to return received data Modified the test LoopbackServer so that it can return the received data in the helper methods.

I ended up having to copy 40+ files from `corefx` into my [project](https://github.com/OctopusDeploy/Octopus.Web.Xdt) (awesome that that was possible though!).

However, the CoreCLR implementation is according to [spec](https://github.com/dotnet/corefx/pull/2154). I see that XmlTextReader is [considered legacy](https://github.com/dotnet/corefx/issues/1595), but it is odd that the class is in corefx but not exposed.

This will require keeping around a list of arrays we've filled up so far, however the overhead of this list will be substantially less than the size of the data itself. A visualization of what I'm talking about for a 300-length enumerable: ``` First array: [items 0-31] List of arrays: [0]: [items 32-63] [1]: [items 64-127] [2]: [items 128-255] Current array: [items 256-299] ``` (I also put this in the comments to help future readers understand.) Then when we need the final array to return from the method, we just calculate `first.Length + list.Sum(a => a.Length) + indexWeFinishedReadingIntoInCurrentArray`, pre-allocate an array of that size, and then copy each of the arrays into that array. I opted to only use this algorithm for enumerables of > length 32, since for smaller sizes it will lead to increased fragmentation, and the overhead of the list allocation will probably be noticeable in comparison to, say, 20 elements. ~32 is also the threshold at around which `Array.Copy` starts getting faster than a for-loop. ## Benchmark results https://gist.github.com/jamesqo/399b72bf5de8e2cbd83d044836cbefa4 (includes results/source code) You can see that the new implementation consistently has about 2/3 the gen0 collections as the old one. The timings are somewhat inconsistent (disclaimer: I only did 100,000 iterations since the tests were taking way too long to run), but you can see that the new implementation is generally faster/the same speed as the old one. (I suspect it may be hard to measure the differences due to all of the interface invocations that are going on, in addition to the covariant array type checks if T is a reference type.) cc @stephentoub @VSadov @JonHanna 11211 area-System.Net HttpWebRequest.GetRequestStream not allowing payload on GET requests Issue initially reported on PowerShell/PowerShell#2054 Making a HTTP GET requests from PowerShell using either Invoke-WebRequest or Invoke-RestMethod with a content-body throws an exception.

The underlying issue is that the default value of `ConnectionLeaseTimeout` is set to `-1`, infinite. It'll only close on dispose of the client, which is very inefficient. The fix is to update the value on the service point like this: ``` csharp var sp = ServicePointManager.FindServicePoint(new Uri(""http://foo.bar/baz/123?a=ab"")); sp.ConnectionLeaseTimeout = 60*1000; // 1 minute ``` Unfortunately, there's no way to do this with .NET Core today. Either ServicePointManager should be brought over to .NET Core or similar equivalent functionality should be enabled some other way.

This commit removes the checks for valid input and allows inflation regardless of input. - This does have the downside of reducing efficiency in the scenario where we are actually out of bytes to read.

In reality these build-infos come from ProjectK and ProjectKRel. Assumption: we will build any remaining TFS-side part of 1.1.0 using ProjectKRel. If that's true, when it starts building 1.1.0 we should change where it posts its build info to `projectk-tfs/release/1.1.0`. We'll also need to change the CoreFX build-info dependency. This will also apply to ProjectNRel. (Producing the NETNative targeting pack.) Does this sound accurate to the branching plan, @weshaggard? /cc @SedarG 11279 area-System.IO Followup on BufferedStream.cs L439 per TODO on https://github.com/dotnet/corefx/blob/dev/api/src/System.IO/src/System/IO/BufferedStream.cs#L439 11282 area-System.Runtime Proposal: Add support for 'precompiled' inputs to String.IndexOfAny/LastIndexOfAny "## Background `IndexOfAny` has to go through a string and see if any of the characters match one in a specified character array. Here is an example of how it could be implemented: ``` cs public static int IndexOfAny(this string s, char[] anyOf) { for (int i = 0; i < s.Length; i++) { for (int j = 0; j < anyOf.Length; j++) { if (s[i] == anyOf[j]) return i; } } return -1; // not found } ``` This implementation can be extremely inefficient for larger arrays, however, since it requires making a pass over the array for every char in the string. So, the [current implementation](https://github.com/dotnet/corert/blob/master/src/System.Private.CoreLib/src/System/String.Searching.cs#L98-L99) does a trick to speed this up. What it does is, before actually going through the string, it 'compiles' the char array down to a 256-bit long ""probabilistic map."" It takes each char and splits it into 2 bytes M and N, and sets the Mth and Nth bits of the map to indicate that those bytes are present in the array. When it wants to see if a char is in the array, it first checks if the 2 bytes corresponding to the char are set. Assuming there are no ""collisions,"" (one char that steals bytes from 2 different chars, which will not happen for ASCII data), checking if the array contains a char is now O(1). ## Problem This probabilistic map has to be re-compiled for every input array. Even if the exact same array is passed multiple times to `IndexOfAny`, which means the exact same bitmap will be generated, it will still have to re-initialize and fill out the same map every time. This can particularly hurt with large arrays; for example, I posted findings in [this issue](https://github.com/dotnet/corefx/issues/10973#issuecomment-243640020) that initializing this map was consuming **as much as 60% of CPU time** in `Path.Combine`, in spite of all of the other allocations going on in the method. ## Proposal: Pre-compiled Probabilistic Maps I propose adding an API that would allow end-users to ""precompile"" the map before passing it in to `IndexOfAny` / `LastIndexOfAny`. If this is a frequently used function in their code, then this will undoubtedly result in performance gains since there is no ""initialization"" work to be done prior to processing the string. (Of course, people will still be free to use the `char[]`-based overload.) Here is a prototype of what this API could look like: ``` cs namespace System { public class String { // Existing API public int IndexOfAny(char[] anyOf); public int IndexOfAny(char[] anyOf, int startIndex); public int IndexOfAny(char[] anyOf, int startIndex, int count); public int LastIndexOfAny(char[] anyOf); public int LastIndexOfAny(char[] anyOf, int startIndex); public int LastIndexOfAny(char[] anyOf, int startIndex, int count); // New API public int IndexOfAny(ProbabilisticMap anyOf); public int IndexOfAny(ProbabilisticMap anyOf, int startIndex); public int IndexOfAny(ProbabilisticMap anyOf, int startIndex, int count); public int LastIndexOfAny(ProbabilisticMap anyOf); public int LastIndexOfAny(ProbabilisticMap anyOf, int startIndex); public int LastIndexOfAny(ProbabilisticMap anyOf, int startIndex, int count); } } namespace System.Text { public class ProbabilisticMap { public ProbabilisticMap(char[] anyOf); // All of the ""compilation"" work is done here } } ``` `ProbabilisticMap` would internally hold references to the char array and the bitmap. These members would be accessible from the String functions, but not from end-user code. We would make a defensive copy of the `anyOf` array to prevent the map from changing if the user mutated the array after passing it to the constructor. ## Usage Typical usage would involve caching the `ProbabilisticMap` in a static field and then passing it to `IndexOfAny` from a function. For example, here is how [this snippet](https://github.com/jamesqo/corefx/blob/1962d3f68e4d547cd1904f435e939c63b137cf1d/src/System.Private.Uri/src/System/Uri.cs#L1710-L1717) from `Uri.CheckForColonInFirstPathSegment` could be rewritten: ``` cs private static readonly ProbabilisticMap s_pathDelimsMap = new ProbabilisticMap(new char[] { ':', '\\', '/', '?', '#' }); private static bool CheckForColonInFirstPathSegment(string uriString) { int index = uriString.IndexOfAny(s_pathDelimsMap); return (index >= 0 && uriString[index] == ':'); } ``` What are your thoughts on this? /cc @benaadams, @GSPP, @omariom " 11283 area-System.Linq Some small expression visitor optimizations Noticed a few places where `ExpressionVisitor` and derived types can save some memory allocations: - `VisitNew` reads `Arguments`, possibly causing allocation of a `ReadOnlyCollection`; it can use `IArgumentProvider` - `VisitBlock` - in `ExpressionVisitor` mimics `VisitArguments` but in a more convoluted way with no clear benefit; it can be simplified a bit - in `ExpressionQuoter` reads `Expressions`, possibly causing allocation of `ReadOnlyCollection`; it can use the same logic as the base class - the logic used in both of these can be centralized in `ExpressionVisitorUtils` to reduce code copies - `VisitLambda` in `ExpressionQuoter` can avoid a `Push` into the scope stack when `Parameters` is empty 11284 area-System.Runtime Move `List` and `EqualityComparer/Comparer` to CoreLib 11285 area-System.Linq Some memory optimizations in expression visitors This fixes issue #11283.

It is redundant to specify the key twice, like this: ``` C# var dictionary = new Dictionary { {123, new Foo(123, ""hello"")}, {987, new Foo(987, ""world"")} }; ``` One solution is to use the abstract class [`KeyedCollection`](https://msdn.microsoft.com/en-us/library/ms132438%28v=vs.110%29.aspx) like this ``` C# class MyKeyedCollection : KeyedCollection { protected override int GetKeyForItem(Foo item) { return item.Id; } } var collection = new MyKeyedCollection { new Foo(123, ""hello""), new Foo(987, ""world"") }; ``` The problem with that is that you have to create a custom class each time you use it. My suggestion is to create a Dictionary that take a Func in the construction to be used to get the key from the value. ``` C# var directory = new KeyedDictionary(x => x.Id) { new Foo(123, ""hello""), new Foo(987, ""world"") }; Debug.WriteLine(directory[123]); Debug.WriteLine(directory[987]); public class KeyedDictionary : IDictionary { private readonly Func _keyGetter; private readonly IDictionary _dictionary = new Dictionary(); public KeyedDictionary(Func keyGetter) { _keyGetter = keyGetter; } public void Add(TValue value) { var key = _keyGetter(value); _dictionary.Add(key, value); } IEnumerator IEnumerable.GetEnumerator() => GetEnumerator(); public IEnumerator> GetEnumerator() => _dictionary.GetEnumerator(); public void Clear() => _dictionary.Clear(); public bool Contains(KeyValuePair item) => _dictionary.Contains(item); public void CopyTo(KeyValuePair[] array, int arrayIndex) => _dictionary.CopyTo(array, arrayIndex); public bool Remove(KeyValuePair item) => _dictionary.Remove(item); public int Count => _dictionary.Count; public bool IsReadOnly => _dictionary.IsReadOnly; public bool ContainsKey(TKey key) => _dictionary.ContainsKey(key); public bool Remove(TKey key) => _dictionary.Remove(key); public bool TryGetValue(TKey key, out TValue value) => _dictionary.TryGetValue(key, out value); public ICollection Keys => _dictionary.Keys; public ICollection Values => _dictionary.Values; public TValue this[TKey key] { get { return _dictionary[key]; } set { throw new NotSupportedException(); } } void ICollection>.Add(KeyValuePair item) { throw new NotSupportedException(); } void IDictionary.Add(TKey key, TValue value) { throw new NotSupportedException(); } } ``` " 11292 area-System.Net Cannot set udpClient.ExclusiveAddressUse = false in macOS and Linux "I originally posted this as a comment to this closed issue: https://github.com/dotnet/corefx/issues/8552#issuecomment-243579967 Since the issue is somewhat different, I decided to open a new one.

" 11295 area-System.Net NetworkStream.Write does not send all bytes to the socket I'm not (yet :-) running .NET Core on my ARM platform, but I have been running into an issue with Mono in the NetworkStream class that's part of their implementation from the shared source. I have created https://bugzilla.xamarin.com/show_bug.cgi?id=43902 and try to create awareness of an assumption in a comment that's not true. For convenience, here is a copy of the issue: My setup is a program that saturates a network link by `Write`ing `byte[]` buffers of length 16384 until exactly 10 MiB are written. Those are transported via an IPv6 based `TcpClient` from a Linux kernel 3.14.58 USB RNDIS interface to a connected Windows machine. On the Windows machine, I use ncat to write the transported data to a file and verify that exactly 10485760 bytes have been received. The latter sometimes fails for Mono 4.4.1. I have changed the code around the [`chkStreamSocket.Send`](https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/src/System/Net/Sockets/NetworkStream.cs#L505) call in the `NetworkStream.Write` method to actually check the return value. I can see that the returned number of bytes written is not the length of the buffer (I've seen 4512 or 12736 instead of 16384). The comment above the Send call seems to assume that this doesn't happen for blocking sockets, however this isn't true for this `Blocking==true` socket. The amount of failures seems to be directly correlated to the speed of the network connection. On my main development machine, the USB network connection saturates above 100Mbit and the issues are very seldom. On another computer, the saturation is already at 35Mbit and there are multiple occurrences in each 10 MiB blob, so this looks like the socket's internal buffer might not have enough room for all data and only accepts less than the full buffer. 11296 area-System.Net NetworkStream.Write does not send all bytes to the socket I'm not (yet :-) running .NET Core on my embedded ARM platform, but I have been running into an issue with mono where a comment in the shared source isn't true.

CC @VSadov, @stephentoub, @justinvp 11309 area-System.Net [WebSockets] If TCP connection closed without WebSocket close, ManagedWebSocket keeps returning 0-byte frames **Overview:** In some browsers and clients, it is possible to terminate the underlying TCP connection without a proper close handshake. In these cases, `ManagedWebSocket` begins interminably returning 0-byte frames from `ReceiveAsync`. This can be observed using a Safari browser, and running a SignalR sample as described here: https://github.com/aspnet/SignalR-Server/issues/202, but I've produced a candidate fix and a simpler repro (detailed below). **Repro steps** (sorry they are a bit rough, but I needed to use the Node WebSocket client to simulate the things I'm seeing). The repro requires VS+.NET Core tools and Node JS (again, it was the easiest client I could use to exhibit the behavior reliably) 1. Clone https://github.com/aspnet/WebSockets, check out `anurse/websocket-repro` and open the SLN up in VS 2. Run `dotnet restore` in the repo root 3. Run `dotnet run` from the `samples\EchoApp` directory in the repo. 4. Check the output to verify the port number (it should be `5000`, but if not, just adjust the final step as necessary) 5. In another console window, clone https://gist.github.com/anurse/fe87ecf8aa01832a99dd247c64cb4595 (clone URL: https://gist.github.com/fe87ecf8aa01832a99dd247c64cb4595.git) somewhere and `cd` to it 6. Run `node main.js ws://localhost:5000` **Expected results:** ``` ps1 # node main.js ws://localhost:5000 WebSocket Client Connected Received: 'Hello, World' echo-protocol Connection Closed ``` And the log output from the server shows an exception because the underlying stream was closed without a close handshake. This is OK, since the client intentionally terminates the connection abruptly. Though maybe an exception isn't the best way to communicate that, who knows :). **Actual results:** Non-stop output until Ctrl-C is pressed (a few times ;P): ``` Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' Received: '' ``` Same on the server log ``` dbug: Echo[0] Received Frame Text: Len=0, Fin=True: dbug: Echo[0] Sent Frame Text: Len=0, Fin=True: dbug: Echo[0] Received Frame Text: Len=0, Fin=True: dbug: Echo[0] Sent Frame Text: Len=0, Fin=True: dbug: Echo[0] Received Frame Text: Len=0, Fin=True: dbug: Echo[0] Sent Frame Text: Len=0, Fin=True: dbug: Echo[0] Received Frame Text: Len=0, Fin=True: dbug: Echo[0] Sent Frame Text: Len=0, Fin=True: dbug: Echo[0] Received Frame Text: Len=0, Fin=True: dbug: Echo[0] Sent Frame Text: Len=0, Fin=True: ``` What's happening is that the call to EnsureBufferContainsAsync at https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/src/System/Net/WebSockets/ManagedWebSocket.cs#L618 is reading zero bytes from the underlying stream (because it has closed, and is thus reporting end-of-stream as per the Stream contract). However, `throwOnPrematureClosure` is `false`, which causes an empty frame to be returned. This repeats indefinitely as the caller keeps trying to read new frames. Changing `throwOnPrematureClosure` to `true` on this line **fixes the issue**, but I wasn't sure if this was safe to do since it seems intentional. I can send a PR to fix this if that sounds like the right fix. It doesn't seem too unsafe though, since if the stream closes, we should be returning some indication of that rather than an empty text frame. /cc @stephentoub @Tratcher @moozzyk 11310 area-System.Net Remove unnecessary null check in DomainNameHelper Found by a coverity scan cc: @cipop, @davidsh 11313 area-System.Collections [dev/api] Some Serialization tests are failing for System.Collections.Specialized netcoreapp1.1 runs cc: @stephentoub ``` call CoreRun.exe xunit.console.netcore.exe System.Collections.Specialized.Tests.dll -xml testResults.xml -notrait Benchmark=true -notrait category=OuterLoop -notrait category=failing -notrait category=nonwindowstests xUnit.net console test runner (64-bit .NET Core) Copyright (C) 2014 Outercurve Foundation.

We don't need the redundant calls to `ContractUtils` methods in `Release` builds. 11326 area-System.Linq Reducing closure and list allocations in LambdaCompiler This addresses issue #11323 by: - Changing `WriteBack` delegate to take in `LambdaCompiler` so the closure doesn't have to include `this` - Splitting `AddressOfWriteBack` methods by adding a `Core` method to avoid closure allocation - Reducing closure size by reduce the number of locals needed in the write-back - Removing cleverness in `EmitArray` where a callback was used by inlining the logic in its single call site - Lazily allocating `List` at the point it's needed, using `null` to represent no write-backs - Using `List` instead of `IList` for `foreach` so it binds to struct-based `GetEnumerator` CC @VSadov 11327 area-System.Linq Consider caching some MemberInfo object that are frequently obtained "Most notably in `LambdaCompiler` and `ILGen`, we have a bunch of places where we call reflection repeatedly and allocate `Type[]` arrays to do so, e.g. ``` csharp _ilg.Emit(OpCodes.Callvirt, typeof(MethodInfo).GetMethod(""CreateDelegate"", new Type[] { typeof(Type), typeof(object) })); ``` We can use a lazy initialization pattern much like we do in the interpreter to cache instruction type instances upon first use: ``` csharp _ilg.Emit(OpCodes.Callvirt, s_createDelegate ?? (s_createDelegate = typeof(MethodInfo).GetMethod(""CreateDelegate"", new Type[] { typeof(Type), typeof(object) }))); ``` " 11328 area-System.Linq Reintroduce the use of Type.GetTypeCode in lieu of a custom implementation It seems this member was reintroduced in https://github.com/dotnet/corefx/pull/6815.

This leads to edge cases where one may be trying to retrieve data from an external API and typed the resource incorrectly leading to an OK response, but no data. It also makes testing difficult due to unexpected behaviors. **Expected Behavior** HTTP Protocol specifies the following: > 9.3 GET > > **The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI**. If the Request-URI refers to a data-producing process, it is the produced data which shall be returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process. > ... > > 9.4 HEAD > > **The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response**. > ... Thus, when running a HEAD or GET request to a non-existent resource, you should NOT receive an OK (200) response, but rather, a NotFound (404) as the resource does not exist (i.e. you cannot retrieve whatever information is available at a resource which does not exist). **How to Reproduce** Create a .NET Core Console App Run the following code in Program.cs and notice that success is true and the response's status code is OK (200). Repeat using GET instead of HEAD and notice the same result. ``` using System.Net.Http; namespace ApiTester { public class Program { public static void Main(string[] args) { using (var client = new HttpClient()) { using (var request = new HttpRequestMessage(new HttpMethod(""HEAD""), ""http://www.this.resource.does/not/exit"")) { using (var response = client.SendAsync(request).Result) { var success = response.IsSuccessStatusCode; } } } } } } ``` " 11333 area-System.Net HttpClient Throws An Exception for Requests When the Resource Does Not Exist "**Issue** When issuing a request using HttpClient to a Request-URI (resource) which does not exist, HttpClient throws an exception and does not handle gracefully.

Repeat using different request types other than HEAD or GET. ``` using System.Net.Http; namespace ApiTester { public class Program { public static void Main(string[] args) { using (var client = new HttpClient()) { using (var request = new HttpRequestMessage(new HttpMethod(""OPTIONS""), ""http://www.this.resource.does/not/exit"")) { using (var response = client.SendAsync(request).Result) { var success = response.IsSuccessStatusCode; } } } } } } ``` " 11334 area-System.Linq Caching some reflection calls "This addresses issue #11327 by introducing a centralized place where we perform reflection calls to obtain commonly used members referenced by compiled code emitted for expression trees. We get savings in terms of memory churn due to `Type[]` allocations and avoid calling into reflection each time. A micro-benchmark shows good results: ``` csharp Test( ""C decimal..ctor(int)"", () => typeof(Decimal).GetConstructor(new[] { typeof(int) }), () => CachedReflectionInfo.Decimal_Ctor_Int32 ); Test( ""F Closure.Constants"", () => typeof(Closure).GetField(nameof(Closure.Constants)), () => CachedReflectionInfo.Closure_Constants ); Test( ""M RuntimeOps.Quote()"", () => typeof(RuntimeOps).GetMethod(nameof(RuntimeOps.Quote)), () => CachedReflectionInfo.RuntimeOps_Quote ); Test( ""M MethodInfo.CreateDelegate(Type, object)"", () => typeof(MethodInfo).GetMethod(nameof(MethodInfo.CreateDelegate), new[] { typeof(Type), typeof(object) }), () => CachedReflectionInfo.MethodInfo_CreateDelegate_Type_Object ); ``` produces (`/o+` on Windows 10 with Release bits) ``` C decimal..ctor(int) 00.86479 00.00034 F Closure.Constants 00.04973 00.00033 M RuntimeOps.Quote() 00.06998 00.00038 M MethodInfo.CreateDelegate(Type, object) 00.32893 00.00032 ``` The number of members (lazily) cached is quite low and most of them are like to be looked up multiple times if they're used at least once (e.g. ""if you got one X, you likely have many"" where X could be a `Quote` node, a nested lambda, a `decimal` literal).

This is causing many networking tests to randomly fail due to resource exhaustion caused by so many simultaneous PR runs on the same CI machines. This occurrs not only when using an external test server endpoint (corefx-net.cloudapp.net) but also loopback servers. To improve engineering efficiency for the team, we are moving most of the tests in the networking libraries from the default CI runs (innerloop). For developers working on networking libraries, the networking tests can be run by invoking the ""outerloop"" tests. We will not be allowing any merges of PRs in the networking libraries unless the outerloop tests are also run by the developer. This affects tests in the following libraries right now: - System.Net.Http - System.Net.Http.WinHttpHandler - System.Net.Sockets - System.Net.Security - System.Net.WebSockets.Client I will be working on fine tuning these exclusions (issue #11345) to try to bring back tests into the innerloop runs when we have begun to address the infrastructure issues. " 11342 area-System.IO Make Stream.CopyTo virtual ## Background Currently for non-seekable streams, the overload of [`Stream.CopyTo`](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/IO/Stream.cs#L191) that does not accept a buffer size defaults to using a 81920-length byte buffer between reads/writes. Although this is under the LOH threshold which is ~85K, it still generates substantial garbage for the GC to clean up, especially for people who are using small streams and aren't expecting such a gigantic buffer to be used. ## Proposal We should make `Stream.CopyTo(Stream, int)` virtual. This would allow `byte[]`-based Streams, such as `MemoryStream`, to avoid using an intermediary buffer altogether, resulting in substantial memory savings. The corresponding async version, `CopyToAsync(Stream, int, CancellationToken)`, is already virtual, so IMO there's no reason it shouldn't be done for this overload as well. ## Proposed API ``` cs namespace System.IO { public abstract class Stream { public void CopyTo(Stream destination, int bufferSize); // existing public virtual void CopyTo(Stream destination, int bufferSize); // new } public class MemoryStream : Stream { public override void CopyTo(Stream destination, int bufferSize); } } ``` 11343 area-System.Linq A few System.Linq.Queryable.Tests issues on AOT Four test failures: ``` System.Linq.Tests.QueryFromExpressionTests.ConditionalNotNotEqualAddPlusConstantNegateConstant System.PlatformNotSupportedException : UnsupportedExpressionType, UnaryPlus System.Linq.Tests.QueryFromExpressionTests.ConditionalNotNotEqualAddCheckedPlusConstantNegateCheckedConstant System.PlatformNotSupportedException : UnsupportedExpressionType, UnaryPlus System.Linq.Tests.ElementAtTests.IndexEqualsCount Assert.Equal() Failure Expected: index Actual: ArgumentOutOfRange_Index System.Linq.Tests.ElementAtTests.EmptyIndexZero Assert.Equal() Failure Expected: index Actual: ArgumentOutOfRange_Index ``` 11345 area-System.Net Re-enable more networking tests for innerloop PR #11341 moved the majority of networking tests to outerloop due to infrastructure issues.

Consequently, it would make sense for it to have all the functionality that `String` has, with in-place mutating versions where appropriate. Right now it has a subset that doesn't seem particularly coherent - e.g. there's indexing, but no `Substring`. Some other missing members include `IndexOf`, `Contains`, `Find`, `Pad...`, `ToLower` and `ToUpper` etc. Basically, it should be possible to do anything you could do with a `String` without actually creating a string (to avoid unnecessary copies). There is also a matter of consistency - the same pattern with an immutable value class and a mutable builder version is also repeated with `Uri` and `UriBuilder`, but there the builder does actually reproduce the API surface of the immutable class much closer. 11391 area-System.Runtime A generic API for string-like objects ".NET is missing a convenient way to define a method that can take something ""string-like"" with minimal overhead. Most existing APIs just take `String`, meaning that callers need to call `ToString`, often creating full copies that are then used only to look at a few characters at the beginning. Some types that are commonly affected by this are `StringBuilder` and `Uri`. This could be solved by adopting a common interface like `IString` for all these types, which could offer the same operations that `String` does; and implementing that interface on all standard types that have string as a public representation of any valid value. The closest existing equivalent is Java `CharSequence`. " 11392 area-System.Net HttpClient performance issue compare to the full framework "I'm trying to wrapper a backend REST API to Frontend.

I'm unclear why it was made public, and I can only find references from within the `System.Linq.Expressions` assembly. Should it be made `internal` again? Note that the constructor does not perform argument validation; this is assumed to be done by the factory that calls it. As such, if one would be able to call this constructor, one could construct an expression that does not type check or has `null` components. 11400 area-System.Linq Expression could have a compact subtype "In particular, when `TailCall` is set to `false` and `Name` is set to `null` (which are both common), we don't need the fields for them. Specialized subtypes are commonly used across the code base. AFAIK, the `Name` and `TailCall` options were added in the 4.0 wave, and the existing `LambdaExpression` type was maybe not considered for this type of specialization despite the addition being made to it. Some other cases could be considered but need to be weighed: - No custom `_delegateType` is set - Common, given the language binding to `Expression` - The `Type` property would have to perform `typeof(TDelegate)` upon each access - An empty `Parameters` collection - Sometimes used in `Expression.Lambda>(e).Compile()()` to eval an expression - We'd only save the reference; a singleton instance of `ReadOnlyCollection` is already used I did a quick analysis for a workload here in Bing, where we keep a ton of user-supplied lambda expressions alive (for a variety of reasons, we can't just compile them and throw away the expression as well; we need them around for persistence, runtime analysis, and more). These also have a bunch of inner lambdas (they're effectively Rx/LINQ queries), and none of them have a non-default `Name`, `TailCall`, and `Type`, so savings would pay off. In terms of frequency of parameter count: - 1 is the leader by far (due to the large number of LINQ-style methods a la `Where` and `Select`) - 2 comes next (mostly due to `SelectMany`'s `resultSelector` argument) - 0 comes next but these tend to be short-lived for us (due to use for expression eval) - 3 and above shows a long tail with blips here and there (due to us hoisting constants into parameters to reuse ""templates"") When used with LINQ, the first two cases are extremely common: ``` csharp var res = from m in typeof(Queryable).GetMethods() from p in m.GetParameters() let t = p.ParameterType where t.IsGenericType let d = t.GetGenericTypeDefinition() where d == typeof(Expression<>) let f = t.GetGenericArguments()[0] let i = f.GetMethod(""Invoke"") group p by i.GetParameters().Length into g orderby g.Count() descending select new { g.Key, Count = g.Count() }; ``` yields ``` { Key = 1, Count = 67 } { Key = 2, Count = 20 } ``` Across `mscorlib`, `System`, and `System.Core`, sorting occurrences of delegate-typed parameters in methods by parameter count yields: ``` { Key = 1, Count = 1184 } { Key = 2, Count = 807 } { Key = 0, Count = 62 } { Key = 3, Count = 26 } { Key = 4, Count = 14 } { Key = 5, Count = 6 } ``` If these methods are used within an expression tree using lambda arguments, this would directly lead to the allocation of these expression nodes. From this, it seems that specialized subtypes based on the number of parameters (likely not beyond a count of 2) are worth considering as well, much like `BlockExpression` has specializations based on the number of expressions, with a lazy allocation pattern for the `ReadOnlyCollection` when `Parameters` is accessed. However, it's rather common for expression visitors to step on this property e.g. for scope tracking purposes. Without a publicly exposed `IParameterProvider` analog to `IArgumentProvider`, it'd likely be of limited use though `LambdaCompiler`, `VariableBinder`, `StackSpiller`, `LightCompiler`, and `ExpressionQuoter` could avoid accessing the property directly, thus preventing growth of these nodes when fed into the compiler. Both the factories and the stack spiller call the constructor of `Expression` today, so these would have to use a `Make` and `Update`/`Rewrite` pattern to construct the specialized subtype. " 11401 area-System.Linq Avoid some allocations in LambdaCompiler Mostly minor things that caught my attention while working in this code, e.g. the use of `Map` and `AddFirst` helpers for allocating arrays and copying them when it can be avoided. 11402 area-System.Linq Removing some unncessary allocations in LambdaCompiler This addresses issue #11401. 11406 area-System.Diagnostics System.Diagnostics.StackTrace: Use loaded PE image in TryGetPEReader if possible "> During my recent SOS portable PDB work, I found that there are times when the ""loadedPeAddress"" actually points to a file based layout.

The loader is kind of a black box and the layout can depend on the platform (Windows may be different that Linux) and how the PE is loaded. So for the SOS PDB support I had to plumb through a isFileLayout flag with the loadedPeAddress (which is the opposite sense of isLoadedImage). > > There is some work that still needs to be done on the coreclr and mscorlib StackTraceHelper side to plumb this same flag though to this code.

However, it doesn't seem that member is already exposed for use on our side (need to confirm whether that's the plan). In the meantime, this PR simplified the code to emit `Ldind` and `Stind` instructions by using a `switch` over `TypeCode` values. It also adds a bunch of tests; only the `Int32` case was covered before. 11409 area-System.Linq Fill some code coverage gaps in LambdaCompiler There are some notable gaps for non-trivial pieces of code. A few are listed below: - `EmitMethodAndAlso` and `EmitMethodOrElse` - `EmitBranchNot`, `EmitBranchLogical`, `EmitBranchAnd`, `EmitBranchOr` - Some branching with statically determined `null` values - Emit for hashtable switches and other code paths around emit for `Switch` expressions - Constrained virtual calls - Emit for `Dynamic` expressions - Emit for `Goto` expressions - Emit for `Extension` expressions (doesn't seem like reachable code; `StackSpiller` will expand these) - Various cases with nullables and value types 11410 area-System.Linq Conditional compilation of MethodBuilder support in LambdaCompiler This addresses issue #11408 and conditionally compiles the code that supported `CompileToMethod` using an `#if`. All the types to support this method seem to be present, and most of the code is still there, so I decided to keep the code and include it conditionally. We can also remove it if we decide this functionality is deprecated altogether, though in my opinion and from my experience it has value in some service scenarios where computational expressions are constructed at runtime and need to be persisted in order to be reloaded at a later time (*). Also removing some other things that were found to be dead code, and reducing some `using` directives. (*) Some restrictions are bothersome though, in particular the restriction to emit to `static` methods and the lack of support for `Quote` nodes (though we worked around that by translating `Quote` nodes into a series of `Call` nodes to call the expression factory methods at runtime, effectively quoting the data as code). 11414 area-System.Linq ReadOnlyCollectionBuilder included in System.Linq.Expressions but not used "Shows up as dead code when analyzing code coverage as part of #11409. It's included from the `Common` folder and shared with `System.Dynamic.Runtime`. The only reference occurs in `ToReadOnly` in `CollectionExtensions` for a type check. If this type is not shared in / referenced from a single assembly and two copies exist, the type check will never pass if the object is passed across assembly boundaries, thus breaking the no-cloning optimization for the collection. This is done in e.g. `ReferenceArgAssign` in `System.Dynamic.Runtime`: ``` csharp private static Expression ReferenceArgAssign(Expression callArgs, Expression[] args) { ReadOnlyCollectionBuilder block = null; // omitted a bunch of code that will assign `block` if (block != null) return Expression.Block(block); else return Expression.Empty(); } ``` The `Block` factory method calls into `ToReadOnly` but the `as` check for `ReadOnlyCollectionBuilder` won't pass due to the copy of the type existing in the two assemblies. Passing the result of calling `ToReadOnly` to the factory method here won't help either, because the same cloning of code applies to `TrueReadOnlyCollection`, which is also checked for in `ToReadOnly` to avoid copying of the collection. It seems that the right thing to do here is to keep one copy of the code in one assembly. Given that `System.Dynamic.Runtime` has a strong (by design) dependency on `System.Linq.Expressions`, the latter would be the best place to store these types. We'd need to have access to these types across assembly boundaries and likely don't want to make them public (though they may provide value to others, *) so `InternalsVisibleTo` is lurking around the corner. There's very little precedent for this on the `corefx` repo though, with the exception of some stuff in `System.Reflection` assemblies (besides for testing purposes). If we decide that `InternalsVisibleTo` is appropriate here (@stephentoub, @VSadov), we can also de-duplicate the code for `ExpressionUtils` etc. (*) The types that need to be accessed across assembly boundaries are: - `System.Runtime.CompilerServices.ReadOnlyCollectionBuilder` which implements `IList` - `System.Dynamic.Utils.CollectionExtensions` for its `ToReadOnly` extension method Note that we _shouldn't_ expose `TrueReadOnlyCollection` publicly because only `ToReadOnly` should be able to instantiate it and type check for it (in order to guarantee the ""True"" part). Luckily, most occurrences of this type occur in`System.Linq.Expressions`, with the exception of a shared `ExpressionUtils.ValidateArgumentTypes` method which is used across boundaries (but the chance of hitting the code path that instantiates the collection here is extremely unlikely; it requires a delegate whose `Invoke` method has an `Expression<>` type that requires quoting, causing a rewrite of the argument expression to introduce a `Quote` around it). Still, it'd likely be better not to expose these types, and consider `InternalsVisibleTo` or keep the code duplication (and the adverse effects such as unnecessary cloning of collections).

There are a few issues in this area, as discussed below. First, handling of the `decimal` type was broken in both the compiler and the interpreter. All misery comes from the promise made by `TypeUtils.IsImplicitNumericConversion` that `decimal` is a valid target for an implicit numeric conversion (which is in agreement with C# specification section 6.1.2), while the back-ends of the expression compilers do not expect this type to come up. This holds true for the compiler's `ILGen.EmitNumericConversion` method (which expects only conversions involving built-in opcodes rather than a call to an `op_Implicit` method on `System.Decimal`) and for the interpreter's `NumericConvertInstruction` types that don't check for `TypeCode.Decimal` as a valid target type. Second, `TypeUtils.ImplicitNumericConversion` contains a quirk for conversion from `UInt32` to `Int64` (which is valid according to C# specification section 6.1.2). This entry is omitted and an entry for the (unreachable) identity conversion to `UInt32` is in its spot. This causes a `Coalesce` on a `uint?` with a right-hand side of type `long` to fail. Note that `TypeUtils.ImplicitNumericConversion` is only used for `Coalesce` expressions. For things like `Convert` expressions involving e.g. `decimal`, the implicit conversion method will be populated on the node. `Coalesce` doesn't automatically build a lambda expression for its `Conversion` property to represent such a conversion. It'd be a valid option to construct such a lambda during compilation (but no earlier - i.e. in factories or in a `Reduce` call - to avoid breaking changes), but code emitted for a `Coalesce` node with a conversion is suboptimal and involves calling the compiled lambda's delegate, so it makes more sense to fix the emitted IL and interpreter instructions instead. Third, the `LightCompiler.CompileCoalesceBinaryExpression` method omits logic for the implicit numeric conversion case altogether, so any `Coalesce` hitting this code path caused an `InvalidCastException` in the generated `Thunk` method. Note that the third case would correspond to a verification error in case IL instructions were emitted and compiled. We lack a verifier in the interpreter, so errors with invalid (box) types tend to come out as runtime exceptions. We could look separately into a debug-mode switch that adds a ""verification instruction"" after the instructions emitted for a non-void expression, effectively checking whether the object on top of the interpreted frame's evaluation stack has a type that's assignment compatible with the static type of the compiled expression node.

" 11454 area-System.Linq Reduction of assignment expressions yields suboptimal code "Consider the following piece of code: ``` csharp var i = Expression.Parameter(typeof(int)); var e = Expression.Block(typeof(void), new[] { i }, Expression.PostIncrementAssign(i)); var f = Expression.Lambda(e).Compile(); ``` When compiled, the resulting IL looks like: ``` ldloc.0 stloc.1 ldloc.1 ldc.i4.1 add stloc.0 ret ``` The storing into and loading from a temporary is not needed here, because the expression's result is thrown away. Although `LambdaCompiler` has tracking of `void` types during expression compilation (cf. `EmitExpressionAsVoid`) its effectiveness is restricted to plain old `Assign` nodes because other forms of assignment don't reach this far. In fact, `StackSpiller` performs reduction of reducible nodes including the unary and binary (compound) assignment forms. For the case shown above, the `PostIncrementAssign` expression gets reduced to: ``` .Block(System.Int32 $var1) { $var1 = $var2; $var2 = .Increment($var1); $var1 } ``` Note that the load from the temporary in `$var1` does not show in the generated IL. This is because `EmitExpressionAsVoid` can do a bit of damage control when it emits the block's last expression as void and notices it's a side-effect free load from a `Parameter` node. If it wouldn't do that, we'd end up with the even more convoluted code of: ``` stloc.1 ldloc.1 ldc.i4.1 add stloc.0 ldloc.1 // damage has been controlled here pop // by EmitExpressionAsVoid ret ``` Compound assignments and unary prefix assignments don't suffer as much from this because they don't need to allocate a local to hold the initial value prior to executing the functional operation. However, the unary postfix assignments are often used in loop constructs (for better or worse), and we can't optimize that here as most ""offline"" compilers would do. It begs the question whether this is really a job for an expression rewriter that runs prior to compilation, the lambda compiler itself, or an optimizing backend (a la `/o+` in C#). With the first option, an optimizer would perform similar `void` site analysis and when it encounters a postfix unary assignment turn it into the equivalent prefix unary assignment. The second option involves keeping our compiler from emitting suboptimal code but it'd need to avoid eager reduction for this information to trickle down to the right place. For the last option of an optimizing backend (which could take away `stloc`, `ldloc` pairs to the same variable provided the `ldloc` instruction is not a branch target; the C# compiler does this as well) we don't have a spot in the compilation chain today. Note there are some other suboptimal patterns generated by the reduction of assignment operations. In particular, `ReduceIndex` methods store all indexing operands into temporaries, even if they're constants such as `Constant` or `Default`. The constant case is not unlikely to occur when dealing with collection elements. Unfortunately, the tree rewrite taking place here is publicly exposed through the `Reduce` method on these unary and binary nodes, so if we want to do something about this we'd end up with the `StackSpiller` having to call an internal reduction mechanism in order to avoid exposing a breaking change. Finally, #4984 should not be forgotten if we decide to do something here; we don't want to regress the behavior reported there. " 11455 area-System.Linq IIListProvider potential optimizations + refactoring "1. `IIListProvider` currently has a `GetCount(bool)` method, the bool parameter indicating whether we only want to get the count if it's ""cheap"" O(1). I just did a `grep -r 'GetCount(.*false) .` of System.Linq, and it looks like the only place it is ever called with false is [here](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Count.cs#L28). Since the additional bool parameter may hamper readability/performance and forces us to maintain additional logic for `!onlyIfCheap`, we may want to consider changing it to just `int Count { get; }`. The existing usage could become ``` cs if (listProv != null) { int count = listProv.Count; if (count != -1) return count; } ``` 2. `ICollection` has the method `CopyTo` which lets you trade off N interface calls (either the indexer if you are using `IList`, or MoveNext/Current on `IEnumerable`) for 1, the `CopyTo` method itself. This can result in quite substantial perf gains if the collection is large. We should consider adding another interface method to `IIListProvider`: ``` cs bool TryCopyTo(T[] array, int arrayIndex); ``` This can be used whenever the iterator wraps an `ICollection` and it needs to copy some items to an array. One concrete case where it might benefit: ``` cs return array // Take an ICollection .Select(i => i + 10) // Wrap it in an IIListProvider .Append(222) // Call something that uses CopyTo in ToArray .ToArray(); // Call ToArray ``` cc @JonHanna, @VSadov " 11456 area-System.Net HttpClient throws an exception if the WWW-Authenticate header is missing If the server returns a 401 response but does not supply a `WWW-Authenticate` header (in contravention to the RFC requirement), and exception is thrown just as in #11452, and this could be a special case of an unknown scheme. HttpClient on .NET Framework does handle this scenario but returning the 401 to the caller, so I suggest the .NET Core implementation also handles it despite the server doing the wrong thing. 11457 area-System.Linq Enumerable.Average should avoid divisions for length 1 collections Floating point divisions, which occur whenever the / or % operators are used, have a very high latency compared to other instructions. For example in the instruction tables [here](http://www.agner.org/optimize/instruction_tables.pdf) you can see `fdiv(r)(p)` consistently have above-average latencies, reaching as much as 71 cycles for Atom processors (though they're more toned down for newer Intel processors). In [`Enumerable.Average`](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Average.cs#L36) it's used even when the collection's length is 1; instead of doing that, we could just return the first item to avoid the expensive operation. 11458 area-System.Reflection Implements PE checksum calculation Work in progress: needs testing 11460 area-System.Linq Inspection / interception of IL generated by LambdaCompiler "IL generated by `LambdaCompiler` and `ILGen` turns out to be quite tricky to inspect. On desktop CLR, I used to emit IL to an assembly using `CompileToMethod` for offline inspection, or use SOS to `!dumpil`. While the latter still works, it's not an option at runtime, e.g. for testing purposes. In particular, when testing code emit optimizations, we don't have a good option to assert the output. One option is to perform private reflection on `DynamicMethod` to obtain the `byte[] m_iLStream` and use one of the decoders to print it as textual IL. Some code is around to do that on the MSDN blogs, so it's one option worth looking into. In fact, I've been using this over at https://github.com/bartdesmet/ExpressionFutures and it works ok-ish. There are some issues with visualizing some metadata tokens but it may be possible to work around that. It may suffice for testing purposes. An alternative which I've put in place in my https://github.com/bartdesmet/corefx/tree/CheaperClosures branch is an indirection of `ILGenerator` calls through an interface, currently only when a conditional compilation symbol is set. Unfortunately, one can't derive from `ILGenerator` because it only has `internal` constructors (and one of its `Emit` overloads is not `virtual` either), so an additional interface has to be put in place. My implementation logs all the calls made, so a `ToString` can be obtained. Note that the last option offers some benefits because one could implement e.g. an optimizing back-end by capturing the emitted instructions and run a post-process step on it (assuming we add one additional method call to ""bake"" the emitted IL, which could flush to the underlying emitter target after running post-process steps): ``` csharp interface IILGenerator { void Emit(OpCode opcode); // quite a lot more methods, see ILGenerator void Bake(); } ``` An interceptor for logging would implement `IILGenerator` and get passed an `IILGenerator` that's the target to emit to. Its `Bake` method can simply forward to the underlying generator; every other method forwards and logs to populate data structures that allow for pretty printing. An optimizer would implement `IILGenerator` but won't forward the `Emit` methods directly; it'd build up internal data structures that are used upon a call to `Bake` to run optimizations prior to making `Emit` calls to the underlying generator, followed by a `Bake` call. Of course, this would add a level of indirection with virtual calls, unless `ILGenerator` would implement such an interface (and make the `Emit(OpCode, sbyte)` overload `virtual`) so there's no additional cost if no wrapper is installed around the `ILGenerator` obtained from `DynamicMethod`. See https://github.com/dotnet/corefx/issues/11454 for a case where such a back-end could provide value. I got the last thing implemented (including an inspector and a basic optimizer) in an offline copy here in Bing, which is based on a fork of the expression API a few years back. I'll to port it to CoreFX as a proof of concept so the merits can be debated with some concrete piece of code to back it up.

This method calls async method and then synchronously processes the result retrieved with Task.Result. The async method may take up to 700 ms. Assume I can't use await, because external network engine provides synchronous interface and I need to check async call result before returning. During run the simulation will decrease time between requests until deadlock occurs - after that point currently awaiting requests will never be completed. I set TP to low threads number to show the problem. It will also happen on 200 and 1000 threads but it will just take more time and will require modifying the simulation code for more requests. In a real app you will never want to set max threads to big numbers because it will make your app very slow (context switching thing) and also each thread takes 1 MB RAM. This example proves that absolutely any blocking call to `Task.Result` or `Task.Wait` from `ThreadPool` thread will work for some time but will eventually deadlock your application in truly high load scenario. Using these methods from `ThreadPool` thread for waiting is always a mistake and should be disallowed (but I understand that it will not happen for compatibility reasons). Yes, we all know from docs that mixing async and blocking ""may cause deadlocks"" but previously I thought about this only in a way ""do not block with `.Result` thread which synchronization context may be required to complete the waited task itself"". TP deadlock is not obvious and many people will ""just use `.Result`"" without ever encountering it during testing. What do you think? May be some workarounds inside .NET TP?

The proposal is to add constructor overloads so that the conversions don't happen and `Value` gets the expected type. The usage stays the same as before, e.g. `[DefaultValue(UInt64.MaxValue)]`. Doing this would be technically a source breaking change, since recompiling existing code would end up with a different type for the boxed `Value`. (Arguably, it would be a better type, but that doesn't change the fact that someone could rely on the old behavior.) ### Proposed API ```c# public class DefaultValueAttribute : Attribute { // existing constructor overloads: public DefaultValueAttribute(Type type, string value); public DefaultValueAttribute(char value); public DefaultValueAttribute(byte value); public DefaultValueAttribute(short value); public DefaultValueAttribute(int value); public DefaultValueAttribute(long value); public DefaultValueAttribute(float value); public DefaultValueAttribute(double value); public DefaultValueAttribute(bool value); public DefaultValueAttribute(string value); public DefaultValueAttribute(object value); // added constructor overloads: public DefaultValueAttribute(sbyte value); public DefaultValueAttribute(ushort value); public DefaultValueAttribute(uint value); public DefaultValueAttribute(ulong value); } ``` ## Original proposal Most numeric types have their constructor but not the unsigned ones. As a result, if you write that code: `new DefaultValueAttribute(UInt64.MaxValue);` The float constructor will be called as the compiler seems to avoid the constructor that needs boxing. Removing all explicit constructor that takes numeric types solve the issue. They all points to the same code that will box the value anyway: ``` /// /// Initializes a new instance of the class using a Unicode /// character. /// public DefaultValueAttribute(char value) { this.value = value; } ``` 11467 area-System.Linq More optimizations for LINQ methods I've been raising a lot of issues about LINQ recently, so this is sort of an umbrella issue for all of the optimizations I think could be applied. - `Enumerable.Cast` is one of those functions that has a 1:1 mapping, so it should forego `yield` and instead implement a custom iterator class. Things like `x.Cast().ToArray()` are very common. - In `OfType`, if `TResult` is object or the source enumerable is of type `IEnumerable` *, we know that each is check will return true and therefore we will have a 1:1 mapping. We can forward to `CastIterator` for those cases and get special treatment for `ToArray`, `ToList`, etc. \* I don't know how often this optimization will happen. Though it will incur no runtime cost since `typeof(T) == typeof(U)` is jitted away, it's not very common for someone to call `OfType()` on something they _know_ is an `IEnumerable`. The only places where I think it can happen are if they accept an `IEnumerable` and use `OfType` to convert it to a generic one, or their method has multiple type parameters and they want to convert an `IEnumerable` to an `IEnumerable` and someone calls their method with `Method()`. # - `Enumerable.Concat(...).ToArray()` is wasteful since it does not attempt to specialize if the underlying enumerables are `ICollections`. It should instead call `GetEnumerable` on everything, and then specialize for `ICollection`. (potentially `IIListProvider` as well if #11455 is implemented) - It may be possible for the `Concat` iterators to implement certain `IPartition` methods as well. If the first/last collections are ILists/IPartitions, then `TryGetFirst` and `TryGetLast` could be implemented with relatively minimal overhead. (actually not in the case where you have a very long linked list of `Concat` iterators and you try to get the first item, but in that case calling `First()` would still be very slow anyway.) # - [`LongCount`](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Count.cs#L79) is not optimized for ICollection/IIListProvider? # - `DefaultIfEmpty` should just return a cached iterator if the enumerable is empty. We should also introduce something like a `WrapperIterator` class that just provides a view over an enumerable, and use that for the other case. I'm sure it could be useful in many other LINQ methods (for example, possibly `Skip(0)`). 11468 area-Meta Move master to netcoreapp1.2 move everything in master from netcoreapp1.1 to netcoreapp1.2, because netcoreap1.1 is shipping earlier 11469 area-Meta Merge dev/api into master Check this first - are there any tests disabled in dev/api that are not disabled in master. re-enable these or open an issue. - check packages don't have broken dependencies, - check packages where the contract exists but the implementation is not complete yet because we are either using stubs or even worse we just have a apicompat baseline but the members don’t even exist in the implementation. 11471 area-System.Net Uri.CreateUriInfo is locking on a string https://github.com/dotnet/corefx/blob/ca9e2b068e75898a3b35860632b1fec01cc5af93/src/System.Private.Uri/src/System/Uri.cs#L2199-L2206 ``` C# lock (_string) { if ((_flags & Flags.MinimalUriInfoSet) == 0) { _info = info; _flags = (_flags & ~Flags.IndexMask) | cF; } } ``` This is a scalability concern, e.g. this Uri could end up sharing the same lock as another that's locking on the same string instance, such as if the string is interned. Now, given the rarity of this, this might be the best option, as unless there's another object available on which to lock, this is likely the better option than allocating a new object per Uri just for the purposes of this lock. If there's another existing object that could be used that's not shared, that would be better. Even better would be getting rid of this lock entirely... since Uri to my knowledge is not deemed to be thread-safe, the purpose of this lock is unclear to me... maybe it could just be removed entirely? 11473 area-Meta Rewrite benchmarksgame samples to optimize performance I realize this not just .NET Core issue.

Many servers use custom auth schemes. A few don't even send a `WWW-Authenticate` header in the response at all (technically against RFC7235). To handle these cases and to match Desktop behavior, we ignore the error from WinHttpQueryAuthSchemes.

If all of the inputs to `Enumerable.Concat` are ICollections, (which is common, at least in code I've written) then we can optimize much better if it is called `ToArray` or `Count` on. This change introduces 2 new iterators for Concat, `Concat2CollectionIterator` and `ConcatNCollectionIterator`, and renames the existing ones to `Concat{2,N}EnumerableIterator`. The main difference with these iterators is: - It has a better implementation for `ToArray`. Previously we just called `EnumerableHelpers.ToArray` if a `Concat` iterator was returned `ToArray` on. However, if we know that all of the enumerables are ICollections, we can sum their counts to allocate an array of exactly the right size, and then call `CopyTo` on each of them to fill the array. (This is a bit tricky in `ConcatNCollectionIterator` since we hold a reference to the most recently `Concat`'d collection, so we have to `CopyTo` the collections in reverse order.) - We no longer pessimize `GetCount(true)`, since we assuming that accessing the `Count` property of the collections will be cheap (at least, cheaper than manually enumerating them), and we just sum the count of all of them. Any input that implements `ICollection` will use these iterators. However, as soon as we see a non-ICollection, we fallback to using a regular `ConcatNIterator`. ## Benchmarks Results/test are [here](https://gist.github.com/jamesqo/0164d1d8229a010e07d225d2d4d8af34). Quite amazingly, there is a 5x reduction in gen0 collections and 40x speedup with the new implementation, at least for length 100 collections. Even for length 3 ones, it's still 4x faster and the # of collections go from 89 => 15 (presumably since we're no longer allocating enumerators). /cc: @JonHanna, @stephentoub, @VSadov 11494 area-System.Reflection Access is denied when use the System.Reflection.DispathProxy HI I used the System.Reflection.DispatchProxy to dynamic a Interface,when use the DispatchProxy.Create();get the Access is denied:'MyProxy',MyProxy is extend the DispatchProxy. 11495 area-System.Linq Add tests for DebugView on Expression This is the next biggest black spot for code coverage in `System.Linq.Expressions`. 11497 area-System.IO ZipArchive CreateMode tries to read Position on non-seekable Stream "Looking at https://msdn.microsoft.com/en-us/library/hh158263(v=vs.110).aspx i find this remark: > If the mode parameter is set to Read, the stream must support reading. If the mode parameter is set to Create, the stream must support writing. If the mode parameter is set to Update, the stream must support reading, writing, and seeking. Based on that i would conclude that using CreateMode, i should be able to write to a non-seekable stream. The [corefx tests](https://github.com/dotnet/corefx/blob/master/src/System.IO.Compression/tests/ZipArchive/zip_CreateTests.cs#L64) for Create also seems to indicate that this is the intention at first glance. However, even in CreateMode, the code attempts to read the Position from the stream it is writing to, unless i am mistaken that is typically not supported on a non-seekable stream? In the abovementioned test a test WrappedStream class is used that can be configured as non-seekable. However, it does support getting a Position which i find a bit strange. I can see that there is also a closed issue on Connect: https://connect.microsoft.com/VisualStudio/feedback/details/816411/ziparchive-shouldnt-read-the-position-of-non-seekable-streams Below is an example that will throw NotSupportedException: ``` using System; using System.IO; using System.IO.Compression; namespace SeekeableStreamBug { public class NonSeekableMemoryStream: MemoryStream { public override bool CanSeek => false; public override long Position { get { throw new NotSupportedException(); } set { throw new NotSupportedException(); } } } public class Program { public static void Main( string[] args ) { using ( ZipArchive archive = new ZipArchive( new NonSeekableMemoryStream(), ZipArchiveMode.Create, false ) ) { var entry = archive.CreateEntry( ""foo"" ); using ( var es = entry.Open() ) { es.Write( new byte[] { 4, 2 }, 0, 2 ); } } } } } ``` " 11499 area-Meta Could not load file or assembly using Microsoft.Extensions.Configuration.Json "Hi everybody, I'm working on a windows 10 IoT project where I want to use Microsoft.Extensions.Configuration.Json so I added it in my project.json in the dependencies: > ""dependencies"": { > ""Microsoft.NETCore.UniversalWindowsPlatform"": ""5.2.2"", > ""System.Xml.XmlDocument"": ""4.0.1"", > ""System.Xml.XPath.XDocument"": ""4.0.1"", > ""Serilog"": ""2.2.1"", > ""Serilog.Sinks.RollingFile"": ""2.2.0"", > ""Microsoft.Extensions.Configuration.Json"": ""1.0.0"" > }, I can deploy my solution but I have this exception: > {""Could not load file or assembly 'System.IO.FileSystem.Watcher, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its > dependencies. > The system cannot find the file specified."":""System.IO.FileSystem.Watcher, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a""} I tried adding System.IO.FileSystem.Watcher to my dependencies in project.json but it didn't solve the problem...

ExclusiveAddressUse socket option is a Windows-specific option that, when set to ""true,"" tells Windows not to allow another socket to use the same local address as this socket. This is only needed on Windows because it otherwise (at least in some versions/configurations) allows any socket with the ReuseAddress option set to ""steal"" the address from a socket that did not have _any_ options set. On Unix, we previously treated this as an ""unsupported"" option. However, it is recommended to set this option to ""true"" on Windows, to avoid malicious theft of a service's address, so we need to support the option, in some fashion, on Unix, so that it's possible to write portable code that works reliably everywhere. Since the _only_ behavior on Linux/OSX is equivalent to ""ExclusiveAddressUse=true"" on Windows, we implement this option as a no-op if it's set to ""true,"" and as an unsupported option if set to ""false."" (It's possible that we could come up with a better failure for the ""false"" case, but I'm treating it as ""unsupported"" for compatiblity with the 1.0 release). Another related option is ReuseAddress. On Windows, this option allows a socket's address _and_ port to be reused. It's equivalent to _two_ native options on Unix: SO_REUSEADDR and SO_REUSEPORT. Again, for portability, we need an option that will work roughly the same way on all platforms. We could introduce a new option (ReuseAddressAndPort?) but existing code is already using the current ReuseAddress option. So this change makes ReuseAddress set both SO_REUSEADDR and SO_REUSEPORT on Unix. If we need to support these options individually, on Unix only, in the future, we'll need to introduce two new options (maybe ReuseAddressOnly and ReusePort) which will likely need to be treated as ""unsupported"" options on Windows. For now, no need for managed support for more fine-grained options has been demonstrated. For more information on the underlying native options on Windows, Linux, OSX, etc., see this great writeup [on stackoverflow](http://stackoverflow.com/questions/14388706/socket-options-so-reuseaddr-and-so-reuseport-how-do-they-differ-do-they-mean-t). Also, the Windows docs [discuss the SO_EXCLUSIVEADDR option](https://msdn.microsoft.com/en-us/library/windows/desktop/cc150667%28v=vs.85%29.aspx) in depth.

We may be able to improve on that to the point where it would be worth overriding, such as by avoiding repeatedly pinning and unpinning. 11572 area-System.IO Investigate optimizing BufferedStream.CopyToAsync BufferedStream doesn't currently override CopyToAsync. We should investigate doing so, as there may be opportunities for optimization. For example, BufferedStream often contains a fairly large internal buffer, potentially larger than the one requested as an arg to CopyToAsync. In that case, BufferedStream's internal buffer could be used instead of allocating a new one. 11573 area-System.Net Investigate overriding NetworkStream.CopyToAsync NetworkStream doesn't override CopyToAsync, instead inheriting the base implementation that calls ReadAsync/WriteAsync in a loop. Each ReadAsync operation in turn creates a task that wraps the internal Socket APM implementation of Receive. Since a CopyToAsync will typically involve many receives, we should investigate overriding it to use SocketAsyncEventArgs, in order to avoid a bunch of the per iteration costs. 11575 area-System.Threading Remove some threading ApiCompat baselines for uap101aot once they are implemented See changes to src/System.Runtime/src/ApiCompatBaseline.uap101aot.txt 11578 area-Meta Consider adding something to the docs about /p:RestorePackages=false I just found out that you can pass in `/p:RestorePackages=false` to skip restoring packages while building a project.

For value types, however, that is not the case, because they can always be copied - for any value type `T`, and for any value of that type, this is valid C# code: ``` T x, y; ... x = y; ``` However, if all you have is a `ValueType`, but you don't know the exact type of the value, there's no way to create an identical copy in a generic fashion. If `ValueType` simply made `MemberwiseClone` public, that would provide a way to do so. Since any actual instance of `ValueType` is always going to be some specific value type, allowing this does not result in any new issues that aren't already exposed by operator `=` on specific value types. Also, having it in the base class effectively makes ""this is value-copyable"" a part of the value type contract clearly and explicitly, unlike the current situation where that contract is implicit and not reified in the type system in any way.

Take for example `Sort`, `BinarySearch`, etc. However, there are a couple of methods where a generic overload is missing, specifically `Clear`, `Copy`, and `Reverse`. This hinders optimizations, since we cannot directly access the elements in the array from C#-- we either have to call `GetValue` and box it, or call into the runtime to do so. So for example, if the array's length is under a certain threshold in `Copy` we would want to stick to a normal for-loop instead of calling into native code. However, since those methods are non-generic, that is currently impossible. The above problem is particularly bad with `Reverse`: if the elements in the array are non-primitive structs, then _every single element_ in the array will be boxed. [Link to source.](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Array.cs#L1602-L1610) In addition, the lack of type safety means that in `Copy`, which accepts 2 `Array` parameters, we have to perform extra type-checking to make sure the arrays match before the actual copy. ## Proposal We should add generic overloads of `Clear`, `Copy`, and `Reverse`. Any code that currently calls the non-generic overloads will automatically light-up to use these methods. (The parameters should have the same names as the non-generic overloads, so this will work with callers who use named parameters as well.) ``` cs namespace System { public abstract class Array : ICloneable, IList, ICollection, IEnumerable, IStructuralComparable, IStructuralEquatable { public static void Copy(T[] sourceArray, T[] destinationArray, int length); public static void Copy(T[] sourceArray, int sourceIndex, T[] destinationArray, int destinationIndex, int length); } } ``` **edit:** @justinvp has already submitted a proposal for a generic `Reverse` which was approved, so I removed that from the proposed API. **edit:** Removed generic `Clear` from this proposal after @terrajobst's comment. That's now being tracked in #11839. 11590 area-System.Linq Expression.Quote rewriting in RuntimeOps.Quote does not preserve type "Repro: ``` csharp using System; using System.Linq.Expressions; using static System.Linq.Expressions.Expression; class Program { public static void Main() { var x = Expression.Parameter(typeof(int)); var f1 = Lambda>( Call( typeof(Program).GetMethod(nameof(F)), Lambda( Block(typeof(void), x) ) ), x ); Console.WriteLine(f1.Compile()(42)); var f2 = Lambda>( Call( typeof(Program).GetMethod(nameof(G)), Lambda( Block(typeof(void), x), x ) ) ); Console.WriteLine(f2.Compile()()); } public static Type F(Expression e) => e.Body.Type; public static Type G(Expression> e) => e.Body.Type; } ``` Output: ``` System.Int32 System.Void ``` We'd expect the first case to print `System.Void` as well, but `RuntimeOps.Quote` rewrites the `Block` because it closes over a hoisted variable `x` and uses the `Block` factory overload that does not supply the original type of the block being quoted. Receivers of a quoted node would not expect it to have changed typing. Modulo any captured variables, one would expect the quote to behave as returning a constant of type `Expression` without any touch-ups to the tree. Note that this issue also manifests itself when a `Block` is using its `Type` to make it look less derived, but after quoting (provided it references a hoisted variable) it will look more derived: ``` csharp var s = Expression.Parameter(typeof(string)); var f3 = Lambda>( Call( typeof(Program).GetMethod(nameof(H)), Lambda( Block(typeof(object), s) ) ), s ); Console.WriteLine(f3.Compile()(""bar"")); ``` In here, the quote observed by method `Program.H` will be of type `String` even though the original `Block` was typed as `Object`.

This will undoubtedly be slower for small collections, and it adds making another pass over the array + renting. However, it will still be faster than the enumerable version which makes 2 virtual method calls per-iteration, since only one virtual call, `CopyTo`, is made for the entire collection. Unfortunately I don't know if the vectorization part is possible since `Sum` uses `checked` arithmetic. Checking if any of the numbers in the vector are negative from overflow, e.g. [here](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/String.Manipulation.cs#L151), will not work since it's possible that some of the ints in the array are negative. 11601 area-Meta Type forwarding makes compiling agains runtime assemblies harder "When compiling code using Roslyn as a library, it's fairly common to compile against framework runtime assemblies, since doing so is much easier than figuring out where reference assemblies are. For example: ``` c# var compilation = CSharpCompilation.Create(assemblyName) .AddReferences(MetadataReference.CreateFromFile(typeof(object).Assembly.Location)); ``` If you need additional assemblies, you find some type from each assembly and use that. Specifically, using `dynamic` requires `Microsoft.CSharp` and `System.Dynamic.Runtime`, so you would add: ``` c# .AddReferences(MetadataReference.CreateFromFile(typeof(Binder).Assembly.Location)) .AddReferences(MetadataReference.CreateFromFile(typeof(DynamicAttribute).Assembly.Location)) ``` This works fine on .Net Framework, but not on .Net Core. The first issue is that on .Net Core, some types are in separate assemblies. Specifically, using `dynamic` also requires `System.Linq.Expressions`: ``` c# .AddReferences(MetadataReference.CreateFromFile(typeof(Expression).GetTypeInfo().Assembly.Location)) ``` This is understandable. What is less understandable is that the assembly that contains `object` and other base types, `System.Private.CorLib` is not enough, you also need to explicitly reference two assemblies that mostly just forward types: `System.Runtime` and `mscorlib`: ``` c# .AddReferences(MetadataReference.CreateFromFile(Assembly.Load(new AssemblyName(""System.Runtime"")).Location)) .AddReferences(MetadataReference.CreateFromFile(Assembly.Load(new AssemblyName(""mscorlib"")).Location)) ``` This is necessary, because `Microsoft.CSharp` references `System.Runtime`, which forwards to `mscorlib`, which forwards to `System.Private.CorLib`. Would it be possible for the `Microsoft.CSharp` runtime assembly (and similar assemblies) to directly reference the assembly that actually contains the types it uses, without any forwarding? It would simplify this kind of code. --- For reference, [here is a complete project](https://gist.github.com/svick/70cb54470f0ea7c8474a03666300f091) showing what I'm talking about.

I also think this has something to do with the `src/redist` folder not present in most projects ## Log [msbuild.txt](https://github.com/dotnet/corefx/files/466171/msbuild.txt) 11605 area-System.Globalization Compat work for Calendars (for Linux) Add the implementation of the added .net standard 1.7 APIs to Linux 11606 area-System.Globalization Compat work for CharUnuicode (for Linux) add the implementation of new added APIs 11608 area-System.Globalization Compat work for collations/Sorting (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11609 area-System.Globalization Compat work for Cultures (Globalization) (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11611 area-System.Globalization Compat work for DateTimeFormatInfo (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11612 area-System.Globalization Compat work for NumberFormatInfo (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11613 area-System.Globalization Compat work for RegionInfo (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11614 area-System.Globalization Compat work for Sortversion (for Linux) 11615 area-System.Globalization Compat work for StringInfo class globalization APIs (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11616 area-System.Globalization Compat work for TextInfo class (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11617 area-System.Globalization Compat work for String class globalization APIs (for Linux) Add missing implementation for the newly added APIs in net standard 1.7 11619 area-Meta Add string reason to all OuterLoop usage in tests Now that OuterLoopAttribute has a ctor that takes a string reason, we should update all OuterLoopAttribute usage to specify the reason the test was demoted to outer loop, e.g. makes network requests, mutates shared state on the machine, takes a long time to run, etc. Some tests already have this in various forms, e.g. a comment next to the [OuterLoop] usage, but we should standardize on including it in the message. And a lot of the usage doesn't specify the reason, forcing a developer who comes along later to try to guess why. 11622 area-System.IO Test failure on Ubuntu:

11658 area-System.IO EncryptFile & DecryptFile not available on all Windows versions These APIs (exposed through File and FileInfo) are entries into EFS functionality. WinRT doesn't expose these particular APIs directly, but has a `FileProtectionManager` class that provides access to EFS (Encrypt is the only currently supported entrypoint). OneCore also does not expose EncryptFile\DecryptFile. Need to follow through on the plausibility of using FileProtectionManager and potentially other entry points into EFS to expose this API in CoreFx on Windows. 11660 area-System.Runtime Dispose of Iterators should be changed to use C# 6 null-conditionals [Currently](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Select.cs#L444-L448) there are many LINQ iterators have code of the form ``` cs public override void Dispose() { if (_enumerator != null) { _enumerator.Dispose(); _enumerator = null; } base.Dispose(); } ``` This has a few problems: - It can lead to a double-Dispose of the enumerator if 2 threads call the method. (probably unavoidable w/o Interlocked) - If `_enumerator.Dispose()` calls `Dispose()` on that iterator it can lead to a stack overflow - It can lead to a nullref if one thread sets it to null, and the other has just checked for null. We should change this to ``` cs // Fixes #3 _enumerator?.Dispose(); _enumerator = null; ``` or ``` cs // Fixes #2 and #3 var enumerator = _enumerator; _enumerator = null; enumerator?.Dispose(); ``` 11661 area-Meta Binding redirects aren't generated for desktop projects when referencing NETStandard-based libraries/installing corefx packages "Steps to repro: 1) Create a new desktop .NET 4.6+ project 2) Add project.json 3) Add a reference to any NETStandard-based library or just install corefx packages 4) Build it **Expected results**: a bunch of facade assemblies are placed in the output folder. The following binding redirects are generated: ``` ``` **Actual results**: only those 3 redirects are emitted: ``` ``` As a result, you're unable to use, say, System.IO.Compression.ZipFile, cause there's no binding redirect for the System.IO.Compression assembly (you'll get a MissingMethodException if you try). So, basically just adding a reference to a portable library may break a lot of things. Sounds like a poor user experience. " 11665 area-System.Runtime Delete Random from corefx System.Random is now exposed publicly from both coreclr and corert, and it's used by code in both repos. As such, we don't also need a copy of it in corefx. We should delete it. We can do so once the seed assemblies for GenFacade have been updated so that the corefx tooling knows Random is also available in corert. 11667 area-System.IO Use ArrayPool in corefx's CopyToAsync implementations FileStream's async mode is handled via #11666, but we can do the same for our other stream-derived types. 11668 area-System.IO System.IO.Compression: ZipArchive loads entire file in memory on .Dispose When you open a `ZipArchive` in Update mode, the entire zip file will be loaded in memory when the `.Dispose` method is invoked. This is because `.Dipose` calls `.WriteFile`, which: - Calls `LoadLocalHeaderExtraFieldAndCompressedBytesIfNeeded` for all entries, which loads the compressed data into memory for those entries - Sets the size of the .zip archive to 0, by calling `_archiveStream.SetLength(0);` - Writes out all entries one by one. As a result: - A lot of memory is used, the compressed data for each entry is loaded into memory - A lot of unnecessary disk I/O is performed, because all entries are written out again, even if they were not modified. An alternative may be to incrementally update the zip archive, and only update entries which changes. 11669 area-System.IO System.IO.Compression: ZipArchiveEntry always stores uncompressed data in memory If a `ZipArchive` is opened in Update mode, calling `ZipArchiveEntry.Open` will always result in the entry's data being decompressed and stored in memory. This is because `ZipArchiveEntry.Open` calls `ZipArchiveEntry.OpenInUpdateMode`, which in return gets the value of the `ZipArchiveEntry.UncompressedData` property, which will decompress the data and store it in a `MemoryStream`. This in its own is already fairly inconvenient - if I'm updating a large file (say 1GB) that's compressed in a zip archive, I would want to read it from the `ZipArchiveEntry` in smaller chunks, save it to a temporary file, and update the entry in the `ZipArchive` in a similar way (i.e. limiting the memory overhead and preferring temporary files instead). This also means that as soon as a `ZipArchive` is opened in Update mode, even reading an `ZipArchiveEntry` which you'll never update incurs the additional cost. A short-term fix may be to expose `ZipArchiveEntry.OpenInReadMode`, which will return a `DeflateStream` instead. If you're doing mixed reading/writing of entries in a single `ZipArchive`, this should already help you avoid some of the memory overhead. 11670 area-System.Diagnostics System.ComponentModel.Win32Exception when trying get Process.StartTime in the exited process on Linux Here example https://github.com/SerhiiS-in6k/Issue-net-core-process/blob/master/Program.cs The exception occurs only on Linux(Ubuntu14.04-x64) on Windows works fine. 11672 area-Meta ILMerge Hi, sorry if wrong repo. What would the best option be to create a dotnet core command line application and publish a single executable for Windows? Is ILMerge still the way to go? Has anyone tried this? 11674 area-System.Net Memory growth of WinHttpRequestState objects I have a web server that accepts an http request and then makes a post request to a bunch of other servers using `HttpClient`. To speed this up we make a `Task` for each request and call `HttpClient.PostAsync` inside each task. These tasks are synchronously waited on with `Task.WaitAny` in order to check the results as they come in. All the code inside the tasks uses async/await. Finally, each task get's a new `HttpClient` but they all use a shared static `HttpClientHandler` which is not disposed when the client is disposed. I have been having issues where out of the blue all of the memory on the server is used up and the number of handles goes through the roof. This happens suddenly over the course of a 10-15 min. Looking at the dumps I have been able to get I can see that most of the handles are rooted in `WinHttpRequestState`. While I am still unsure of the root cause I was looking at `WinHttpHandler` and `WinHttpRequestCallback` and noticed that `WinHttpRequestCallback.RequestCallback` is surrounded in a try/catch, however if any exception is thrown `WinHttpHandler` is not signaled by `WinHttpRequestCallback.RequestCallback` because none of it's `TaskCompletionSource`s are given the exception. Is this correct? If an exception does happen in `WinHttpRequestCallback.RequestCallback` will the task created by `WinHttpHandler.SendAsync` just sit forever? Please let me know if I have missed something.

Noticed during code review that there is a potential memory leak in `GCHandle` and `WinHttpRequestState` instances when `WinHttpHandler.InternalSendRequestAsync()` executed repeatedly from asynchronous `do/while` loop in `WinHttpHandler.StartRequest`. **Cause:** `WinHttpRequestState` may pin `WinHttpRequestState` instances multiple times due to missing `_operationHandle.IsAllocated` check around `_operationHandle = GCHandle.Alloc(this)`: ``` public void Pin() { #if DEBUG Interlocked.Increment(ref s_dbg_pin); #endif _operationHandle = GCHandle.Alloc(this); } ``` Maybe related to issue [#11674](https://github.com/dotnet/corefx/issues/11674) 11694 area-System.Net Add back missing WebSockets APIs Adds back to System.Net.WebSockets: - WebSocketException deriving from Win32Exception - WebSocketException.ctor() - WebSocket.DefaultKeepAliveInterval - WebSocket.CreateClientBuffer - WebSocket.CreateClientWebSocket - WebSocket.CreateServerBuffer - WebSocket.IsApplicationTargeting45 - WebSocket.IsStateTerminal - WebSocket.ReisterPrefixes - WebSocket.ThrowOnInvalidState - WebSocketContext.RequestUri - WebSocketContext.Headers - WebSocketContext.Origin - WebSocketContext.SecWebSocketProtocols - WebSocketContext.SecWebSocketKey - WebSocketContext.CookieCollection - WebsocketContext.User - WebSocketContext.IsAuthenticated - WebSocketContext.IsLocal - WebSocketContext.IsSecureConnection - WebSocketContext.WebSocket (Several of these members just throw PlatformNotSupportedException. Others have a different implementation than on desktop but something that's reasonable for corefx given the rest of the implementation's differences, e.g. limits on buffer sizes). Adds back to System.Net.WebSockets.Client: - ClientWebSocketOptions.UseDefaultCredentials - ClientWebSocketOptions.SetBuffer(int, int) - ClientWebSocketOptions.SetBuffer(int, int, ArraySegment) As part of this, I also: - Updated ClientWebSocketOptions.KeepAliveInterval to default to 30 seconds, as it does on desktop, rather than defaulting to 0. - Updated the managed websockets implementation to take the ClientWebSocketOptions buffer information into account, in particular the receive buffer size and the buffer itself (as long as offset and count don't represent a subset, which would have been a more intrusive change to support). cc: @davidsh, @cipop, @ericeil, @danmosemsft, @anurse (@anurse, you'll notice I made some minor changes to the CreateFromConnectedStream method.

We can avoid all of these issues by recombining FileStream into a partial class like we use elsewhere in corefx. The primary trickiness comes with WinRT, where, depending on the path, we sometimes use Win32FileStream and sometimes use WinRTFileStream. cc: @ericstj, @justinvp, @JeremyKuhne, @ianhays 11708 area-System.Net Failed assert in NegotiateStream_StreamToStream_Authentication_TargetName_Success "I hit this assert when I try to run the System.Net.Security tests (outerloop) locally: ``` System.Net.Security.Tests.NegotiateStreamStreamToStreamTest.NegotiateStream_StreamToStream_Authentication_TargetName_Success [FAIL] System.Diagnostics.Debug+DebugAssertException : Unknown Interop.SecurityStatus value: -2146892976 at System.Environment.GetStackTrace(Exception e, Boolean needFileInfo) at System.Environment.get_StackTrace() at System.Diagnostics.Debug.Assert(Boolean condition, String message, String detailMessage) at System.Net.SecurityStatusAdapterPal.GetSecurityStatusPalFromInterop(SecurityStatus win32SecurityStatus) in c:\Users\stoub\Source\repos\corefx\src \System.Net.Security\src\System\Net\SecurityStatusAdapterPal.Windows.cs:line 74 at System.Net.Security.NegotiateStreamPal.InitializeSecurityContext(SafeFreeCredentials credentialsHandle, SafeDeleteContext& securityContext, Strin g spn, ContextFlagsPal requestedContextFlags, SecurityBuffer[] inSecurityBufferArray, SecurityBuffer outSecurityBuffer, ContextFlagsPal& contextFlags) in c:\ Users\stoub\Source\repos\corefx\src\System.Net.Security\src\System\Net\NegotiateStreamPal.Windows.cs:line 166 at System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean throwOnError, SecurityStatusPal& statusCode) in c:\Users\stoub\Source\re pos\corefx\src\System.Net.Security\src\System\Net\NTAuthentication.cs:line 344 at System.Net.Security.NegoState.GetOutgoingBlob(Byte[] incomingBlob, Exception& e) in c:\Users\stoub\Source\repos\corefx\src\System.Net.Security\sr c\System\Net\SecureProtocols\NegoState.cs:line 787 at System.Net.Security.NegoState.StartSendBlob(Byte[] message, LazyAsyncResult lazyResult) in c:\Users\stoub\Source\repos\corefx\src\System.Net.Secu rity\src\System\Net\SecureProtocols\NegoState.cs:line 443 at System.Net.Security.NegoState.ProcessAuthentication(LazyAsyncResult lazyResult) in c:\Users\stoub\Source\repos\corefx\src\System.Net.Security\src \System\Net\SecureProtocols\NegoState.cs:line 356 at System.Net.Security.NegotiateStream.BeginAuthenticateAsClient(NetworkCredential credential, ChannelBinding binding, String targetName, Protection Level requiredProtectionLevel, TokenImpersonationLevel allowedImpersonationLevel, AsyncCallback asyncCallback, Object asyncState) in c:\Users\stoub\Source\re pos\corefx\src\System.Net.Security\src\System\Net\SecureProtocols\NegotiateStream.cs:line 101 at System.Net.Security.NegotiateStream.BeginAuthenticateAsClient(NetworkCredential credential, String targetName, AsyncCallback asyncCallback, Objec t asyncState) in c:\Users\stoub\Source\repos\corefx\src\System.Net.Security\src\System\Net\SecureProtocols\NegotiateStream.cs:line 60 at System.Threading.Tasks.TaskFactory`1.FromAsyncImpl[TArg1,TArg2](Func`5 beginMethod, Func`2 endFunction, Action`1 endAction, TArg1 arg1, TArg2 arg 2, Object state, TaskCreationOptions creationOptions) at System.Threading.Tasks.TaskFactory.FromAsync[TArg1,TArg2](Func`5 beginMethod, Action`1 endMethod, TArg1 arg1, TArg2 arg2, Object state) at System.Net.Security.NegotiateStream.AuthenticateAsClientAsync(NetworkCredential credential, String targetName) in c:\Users\stoub\Source\repos\cor efx\src\System.Net.Security\src\System\Net\SecureProtocols\NegotiateStream.cs:line 183 at System.Net.Security.Tests.NegotiateStreamStreamToStreamTest.NegotiateStream_StreamToStream_Authentication_TargetName_Success() in c:\Users\stoub\ Source\repos\corefx\src\System.Net.Security\tests\FunctionalTests\NegotiateStreamStreamToStreamTest.cs:line 90 ``` According to https://msdn.microsoft.com/en-us/library/windows/desktop/dd542646(v=vs.85).aspx, that status code is SEC_E_DOWNGRADE_DETECTED (""The system cannot contact a domain controller to service the authentication request.

The [zip file specification](https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT) appendix D specifies how encoding should be handled: > The ZIP format has historically supported only the original IBM PC character > encoding set, commonly referred to as IBM Code Page 437. This limits storing > file name characters to only those within the original MS-DOS range of values > and does not properly support file names in other character encodings, or > languages. To address this limitation, this specification will support the > following change. > > If general purpose bit 11 is unset, the file name and comment should conform > to the original ZIP character encoding. If general purpose bit 11 is set, the > filename and comment must support The Unicode Standard, Version 4.1.0 or > greater using the character encoding form defined by the UTF-8 storage > specification. This creates a problem mainly for European languages: they tend to use a lot of the characters which are present in CP437 but not in ASCII, so you may get inconsistent behavior there. Windows 10 still defaults to CP437 where possible: you can try this by creating a file called Über.txt and zipping it using File Explorer. The filename will be encoded using CP437; but the ZipArchive class decodes it as �ber.txt. Because the zip archive re-creates the individual zip entries when the file is saved in Update mode, this results in data loss when opening & closing the archive, even if that entry is not modified. This appears to be a side-effect of removing CP437 support from .NET Core, although it is still available in the `System.Text.Encoding.Codepages` package (see #10054 for more information). A simple fix would be to have the `System.IO.Compression` package take a dependency on `System.Text.Encoding.Codepages`, but not sure if this is desirable. /cc @ianhays 11718 area-System.Drawing Seg fault in System.Drawing.Primitives.Tests on CentOS in CI http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/dev_api/job/centos7.1_release_prtest/85/ Happened while testing #11688, but this is just adding a new Socket API, so it probably didn't cause this failure. 11719 area-System.Reflection Cleanup MethodInfo tests /cc @stephentoub 11721 area-System.IO Remove CreateManyConcurrent test Adds a conditionalFact to the CreateManyConcurrentInstances test so we don't run the test when max_user_instances is greater than 200.

The problem is that this move happened in a different branch (dev/xml) so when we merged that back to dev/api and then to master, we lost all of the changes that were made in master after the move. This work item is to track the work that must be done to re-apply these changes back to the files now under System.Private.Xml. cc: @weshaggard @danmosemsft @krwq @shmao 11770 area-System.Linq BindingRewriter implementations of StackSpiller have incorrect check for value types Found while investigating #11740. The `BindingRewriter` implementations for `MemberBind` and `ListBind` bindings have an incorrect check for bindings targeting a value-typed property: - When no stack spilling takes places, the code below throws `CannotAutoInitializeValueTypeElementThroughProperty` from the `LambdaCompiler` for the _current_ node (`MemberBind` targeting `C.V`). - When stack spilling takes place, the code below throws `TryNotSupportedForValueTypeInstances` from the `StackSpiller` for a _child_ node (`Bind` targeting `V.X`). ``` csharp #define REPRO using System; using System.Linq.Expressions; using System.Reflection; using static System.Linq.Expressions.Expression; class MI { static void Main() { var i = (Expression)Constant(1); #if REPRO i = TryFinally(i, Empty()); #endif var e = Lambda>(MemberInit(New(typeof(C)), MemberBind(typeof(C).GetProperty(nameof(C.V)), Bind(typeof(V).GetField(nameof(V.X)), i)))); var c = e.Compile()(); Console.WriteLine(c.V.X); } class C { public V V { get; } } struct V { public int X; } } ``` While the behavior of throwing the other exception is fine here, there's explicit code to throw the same `CannotAutoInitializeValueTypeElementThroughProperty` exception under this circumstance, but it gets the check wrong. Rather than checking the _member_'s type, it checks the _target_'s type. Once we address #11740, a correct implementation of this check will be the only thing preventing emitting of semantically unsound stack spilling code because the `RequireNotRefInstance` check would go away. ``` csharp internal override Expression AsExpression(Expression target) { if (target.Type.GetTypeInfo().IsValueType && _binding.Member is PropertyInfo) { throw Error.CannotAutoInitializeValueTypeElementThroughProperty(_binding.Member); } ``` should not use `target.Type` but the `_binding.Member`'s type for the condition of the check. 11771 area-System.Numerics OutOfMemoryException in System.Numerics.Tests.logTest.RunLargeValueLogTests on Ubuntu Running OuterLoop Ubuntu14.04 Debug in CI for #11765: ``` 15:22:12 System.Numerics.Tests.logTest.RunLargeValueLogTests [FAIL] 15:22:12 System.OutOfMemoryException : Exception of type 'System.OutOfMemoryException' was thrown. 15:22:12 Stack Trace: 15:22:12 at System.Numerics.BigInteger.op_LeftShift(BigInteger value, Int32 shift) 15:22:12 at System.Numerics.Tests.logTest.LargeValueLogTests(Int32 startShift, Int32 bigShiftLoopLimit, Int32 smallShift, Int32 smallShiftLoopLimit) 15:22:12 at System.Numerics.Tests.logTest.RunLargeValueLogTests() ``` 11772 area-Meta DotNetCore.1.0.1-SDK installation onto Windows 2008 "DotNetCore.1.0.1-SDK.1.0.0.Preview2-003131-x64 specifically Using Windows Server ""6.0.6002"".

In particular, various `Rewrite` methods simply instantiate expression nodes (e.g. `Unary`, `Loop`, `Switch`, `Try`, `Index`, `AssignBinary`) while others go through factories. We don't need the indirection through factories here because: - typing invariants are enforced at the level of the `Rewrite` methods; they never change types of nodes, so we don't need the factories to type check what we produce internally - compact variants of nodes are not needed; we already create `IList` instances in `ChildRewriter` and unpacking them into efficient layouts for a short-lived node instance is redundant work - nodes produced by the spiller only live until `LambdaCompiler` has processed them - nodes produced by the spiller never have an extended lifetime; e.g. `Quote` operands are not spilled - unpacking collections to create efficient layouts allocates _more_ memory than simply wrapping the list in the `XYZExpressionN` variant of a node 11781 area-System.Linq Reducing indirection through factories during stack spilling rewrites We were about 50/50 in terms of places where we directly call `Make` or use a constructor versus places where we use factory methods for no good reason. Rationale discussed in #11780 but in essence: - we don't need the type/member checks of the factory; at most we rewrite child nodes to variables but retain the original typing, so no need to re-check - we don't need the factory's behavior of creating compact short-lived nodes; we have an `IList` retrieved from `ChildRewriter` anyway - we don't need `ToReadOnly` copy behavior exhibited by a lot of factory methods Also adding some `readonly` modifiers, avoiding interface calls where a concrete type is available, and using `TrueReadOnlyCollection` to wrap arrays that aren't being mutated. 11782 area-System.Linq Adding ILReader for tests that assert emit behavior in LambdaCompiler We have a pretty big blind spot in testing behavior of `LambdaCompiler` especially when it comes to certain optimizations it emits. The `ILGenerator` for the `DynamicMethod` we emit into is pretty much a black box, making it hard to assert behavior. Some options are described in #11460. While I have an `IILGenerator` interface in another local branch, it either requires conditional compilation for tests (to go through the interface abstraction) or the interface indirection should always be enabled. The latter is likely still useful but we need to weigh pros and cons of abstracting the back-end. One place where it could shine is to perform IL-level optimization (a la `stloc`/`ldloc` pair elimination).. I'll push this as a WIP at a later point. In the short term though, as I'm noodling with: - stack spilling (see #11740) - closure creation improvements (see [CheaperClosures](https://github.com/bartdesmet/corefx/tree/CheaperClosures), more to follow) - test cases for `LambdaCompiler` and `ILGen` behavior (see #11409) there's an immediate need to be able to assert generated IL code. Luckily, there's a pretty good IL decompiler for `DynamicMethod` available [here](https://blogs.msdn.microsoft.com/haibo_luo/2010/04/19/ilvisualizer-2010-solution), so I decided to port this to .NET Core. Note I had to work around missing members on `Module` (see #5381), but other than that I've just made the code much more concise using C# 6.0 constructs and excluded some functionality we don't (yet) need. One use case is included to exercise the code and show how to perform IL asserts. 11785 area-System.IO Expose InternalBufferOverflowException in FSW Updates the default targetgroup of filesystemwatcher to netstandard1.7 and exposes InternalBufferOverflowException out of System.IO.FileSystemWatcher. @danmosemsft @joperezr @stephentoub 11787 area-System.Net Port System.Net.Security 11788 area-System.Net Port remaining types/members in System.Net.Sockets # Missing types -

"## Scope Modernize the CookieContainer to fix a 7 year old bug concerning the ability to return ALL cookies for a given domain. ## Rationale A [well documented](http://stackoverflow.com/questions/1047669/cookiecontainer-bug/39536750#39536750) (and entirely too long-standing) bug in the CookieContainer is that `CookieContainer.GetCookies()` only accepts a Uri, not a string. This means you cannot properly retrieve cookies that are prefixed with a dot. This is because URIs prefixed with a dot are invalid. Previously-provided solutions involve using Reflection, but these are not ideal for various reasons... not to mention that the .NET Core version has slightly different internals, so the old solutions no longer apply. I've provided [a complete solution that functions on .NET Core here](http://stackoverflow.com/a/39536750/403765) as an extension method, but it again requires reflection, and has not been vetted for proper security. A proper solution would be to provide a version of `GetCookies()` that accepts a string domain, and is more intelligent about matching that domain, to return all of the Cookies that the user would expect in a given situation. ## Usage Here's a pseudocode example of how this would work. ``` cs public Class SomeClass { private static HttpClient HttpClient; private static CookieContainer Cookies; static SomeClass() { Cookies = new CookieContainer(); HttpClient = new HttpClient( new HttpClientHandler { CookieContainer = Cookies, AutomaticDecompression = DecompressionMethods.GZip, AllowAutoRedirect = false } ); } /// /// /// /// public async Task GetAccessToken() { AuthTicket authTicket; var cookies = Cookies.GetCookies(""sso.somewebsite.com""); // The ""CASTGC"" in this case is actually in the "".sso.somewebsite.com"" domain and would not // be returned in the current codebase. if (!cookies.Any(c => c.Name == ""CASTGC"") || cookies.Count == 0) { authTicket = await Login(); } accessToken = await HttpClient.GetStringAsync(""http://somewebsite.com""); return accessToken; } ``` ## Implementation Based on my Extension Method implementation previously mentioned, the implementation would likely look something like this: ``` cs /// /// Returns all of the Cookies where /// contains part of the specified string. Will return cookies for any subdomain, as well as dotted-prefix cookies. /// /// The string that contains part of the domain you want to extract cookies for. /// public static IEnumerable GetCookies(string domain) { foreach (var entry in _domainTable) { if (entry.Key.Contains(domain)) { foreach (var li in entry.Value._list) { foreach (Cookie cookie in li.Value) { yield return cookie; } } } } } ``` ## Obstacles There may be security implications with this design that I am not aware of, so the final implementation would likely need to pass a security review from @blowdart's team. Might also want to get @benaadams to review the entire CookieCollection code to make sure it is optimized for performance.

This is a feature request for using a DFA/NFA engine whenever possible – that is, on all regexps that don't have backreferences or any other non-regular features. Note that backreferences almost certainly cannot be handled by _any_ efficient algorithm in general – the matching problem for regular expressions plus backreferences is NP hard. 11837 area-System.Linq Remove unnessary list allocations and copies in System.Linq.Expressions We're generally pretty good about only allocating arrays of the size we need, if we know the size upfront. I just noticed a few places where we still use a `List` instead, and then pass it along as-is to expression factory methods which will create a copy as part of the call to `ToReadOnly`. It'd be better to just allocate the array and wrap it in a `TrueReadOnlyCollection` prior to passing it to these factories. 11838 area-System.Linq Reducing list allocations and copying This addresses issue #11837. In places where keeping track of the index of the next element to write into the array is rather clumsy, I'm using a small `ArrayBuilder` helper type which exposes an `Add` method, so the original `List`-like code keeps working and no index tracking is needed. This utility is also responsible to either return the array or return a `TrueReadOnlyCollection` wrapping it (ownership transfer semantics), so we can pass it along to e.g. an expression factory method without causing it to create an unnecessary copy. 11839 area-System.Runtime Proposal: Generic overload(s) of Array.Clear Separated from #11588 ## Background It may be beneficial to provide generic `Array.Clear` overloads that accept `T[]` rather than an `Array`. Since we know the type of these arrays at compile-time and that they're 0-based, we can write the clearing logic inline in C#. This may benefit smaller arrays since we don't suffer the overhead of calling into the runtime, and will eliminate the need for workarounds like [this](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableArray_1.Builder.cs#L107-L109). (For large arrays, of course, we can just continue what we were doing before.) It may also be desirable to provide an overload that does not accept an index/length, e.g. `Clear(T[])`, which clears the entire array. Implementing this will be cheaper than had we done it with `Array`, since we can call `Clear(array, 0, array.Length)` instead of `Clear(array, array.GetLowerBound(0), array.GetLength(0))`. ## Proposed API ``` cs namespace System { public abstract class Array : ICloneable, IList, ICollection, IEnumerable, IStructuralComparable, IStructuralEquatable { public static void Clear(T[] array); public static void Clear(T[] array, int index, int length); } } ``` @terrajobst 11840 area-System.Linq Custom Select/Where implementations should be decoupled from Iterator [EmptyPartition](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Partition.cs#L51) should be override these methods to be nops, but can't since for one to customize these methods you have to [subclass Iterator](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Iterator.cs#L45). Maybe it would be good to have an `IIterator` interface which `Iterator` implements, and then change `IIListProvider` to inherit from `IIterator`. cc @JonHanna 11841 area-System.Linq Small perf tweaks for Select - If the input is an empty array, we know that it's size will never change (even if it is mutated after the `Select` call) so we can return a cached result. - This allows us to delete some code in `ToArray`, `TryGetFirst` and `TryGetLast` for specially handling empty arrays. - `_state - 1` can be used as the index into the array instead of a separate `_index` field. This leaves only 2 pointer-sized fields in `SelectArrayIterator`. - When getting the `Count()` a `SelectEnumerableIterator`, we don't have to run the selector on each element of the sequence. cc @stephentoub @JonHanna @VSadov 11842 area-System.Linq Stack spiller can avoid spilling constants "Stack spilling currently does not consider the node type when allocating temporaries and assignment expressions for child expressions in `ChildRewriter.EnsureDone` when the action is set to `SpillStack`. This leads to redundant temporaries, store, and load instructions in cases where the expression is ""pure"" and has no side-effects that shouldn't be reordered. For example: ``` csharp Lambda>( Add( Constant(1), TryFinally( x, Empty() ) ), x ) ``` produces the following IL: ``` .method int32 ::lambda_method(class [System.Core]System.Runtime.CompilerServices.Closure,int32) { .maxstack 3 .locals init ( [0] int32, [1] int32, [2] int32 ) IL_0000: ldc.i4.1 IL_0001: stloc.0 .try { IL_0002: ldarg.1 IL_0003: stloc.2 IL_0004: leave IL_000a } finally { IL_0009: endfinally } IL_000a: ldloc.2 IL_000b: stloc.1 IL_000c: ldloc.0 IL_000d: ldloc.1 IL_000e: add IL_000f: ret } ``` Spilling in `IL_0001` (and thus the allocation of local `0` and the load in `IL_000c`) is redundant; the load of the constant can safely be moved. Another example is `xs[0] = s` where `s` requires spilling. The constant does not have to be saved into a temporary. This type of optimization can be applied for nodes of kind `Constant` and `Default`. A case could be made for other nodes, such as read-only field accesses, `Quote` and `RuntimeVariables`, etc. " 11843 area-System.Net "IPAddress.Parse(""4294967296"") does not throw FormatException on OS X" "System.Net.IPAddress.Parse(""4294967296"") does not throw FormatException on OS X. ``` $ uname -a Darwin 15.6.0 Darwin Kernel Version 15.6.0: Mon Aug 29 20:21:34 PDT 2016; root:xnu-3248.60.11~1/RELEASE_X86_64 x86_64 i386 MacBookPro11,5 Darwin $ dotnet --version 1.0.0-preview2-003121 ``` Steps to reproduce ``` mkdir foo cd foo dotnet new dotnet restore sed -i '9i Console.WriteLine(System.Net.IPAddress.Parse(""4294967296""));' Program.cs dotnet run ``` The sed command writes `Console.WriteLine(System.Net.IPAddress.Parse(""4294967296""));` to line 9 in Program.cs IPAddress.Parse returns `0.0.0.0` on my Mac when using dotnet run. ``` $ dotnet run Project bug (.NETCoreApp,Version=v1.0) was previously compiled.

The problem is on view, **application prints field name** not the value from attribute." 11848 area-System.Linq Cheaper stack spilling This addresses issue #11842 by avoiding spilling for certain node types. It's very similar to the strategy taken in Roslyn when spilling the stack for `await` expressions. Note that this PR leverages the work done in https://github.com/dotnet/corefx/pull/11782 to assert the generated IL. These tests are currently `#ifdef`'d out until integration of that PR, but I've kept them in this review to aid in visualizing the effects of this optimization. Alas, we didn't have IL-level asserts before, so there's no diff between the original IL produced and the IL after the change. As a point of comparison though, have a look at the sample provided in the issue; its IL now looks like: ``` .method int32 ::lambda_method(class [System.Core]System.Runtime.CompilerServices.Closure,int32) { .maxstack 2 .locals init ( [0] int32, [1] int32 ) .try { IL_0000: ldarg.1 IL_0001: stloc.1 IL_0002: leave IL_000a } finally { IL_0007: endfinally } IL_0008: ldloc.1 IL_0009: stloc.0 IL_000a: ldc.i4.1 IL_000b: ldloc.0 IL_000c: add IL_000d: ret } ``` That's a reduction by two instructions, one local slot, and a drop of `.maxstack` by one. 11851 area-Infrastructure Lots of CI timeouts for Ubuntu14.04 Release Build and Test This has affected at least 4 PRs submitted this weekend. I'll refer to this issue from these occurrences. 11853 area-System.Linq Stack spiller is contagious beyond the spill site The current implementation of the stack spiller will save child nodes to temporaries, even if they occur _after_ the child node that requires an empty stack. This leads to redundant temporaries, store, and load instructions in an amount proportional to the complexity of the tree _beyond_ the spill site. For example: ``` csharp Lambda, int, int>>( Invoke( f, TryFinally( x, Empty() ), Constant(1), Constant(2) ), f, x ) ``` produces the following IL: ``` .method int32 ::lambda_method(class [System.Core]System.Runtime.CompilerServices.Closure,class [mscorlib]System.Func`4,int32) { .maxstack 5 .locals init ( [0] class [mscorlib]System.Func`4, [1] int32, [2] int32, [3] int32, [4] int32 ) IL_0000: ldarg.1 IL_0001: stloc.0 .try { IL_0002: ldarg.2 IL_0003: stloc.s V_4 IL_0005: leave IL_000b } finally { IL_000a: endfinally } IL_000b: ldloc.s V_4 IL_000d: stloc.1 IL_000e: ldc.i4.1 IL_000f: stloc.2 IL_0010: ldc.i4.2 IL_0011: stloc.3 IL_0012: ldloc.0 IL_0013: ldloc.1 IL_0014: ldloc.2 IL_0015: ldloc.3 IL_0016: callvirt instance int32 class [mscorlib]System.Func`4::Invoke(int32,int32,int32) IL_001b: ret } ``` The arguments of `Invoke` beyond the `Try` argument (which requires spilling) don't have to be stored in temporary locals. Yet in this example we see lines `IL_000e` through `IL_0011` perform stores to temporaries in slots `2` and `3` with corresponding loads in `IL_0014` through `IL_0015`. These are redundant stores and loads, thus we can save two locals in this case. Obviously, the situation gets worse when there are more child nodes beyond the spill site. Note that this contagious effect does not limit itself to the node having a child expression that requires spilling; it also travels up the tree affecting all evaluations _after_ the spill site. For example: ``` csharp Lambda>( Add( Add( Add( Constant(1), TryFinally( x, Empty() ) ), Constant(2) ), Constant(3) ), x ) ``` The emitted IL code has 7 locals introduced by spilling even though the minimum required local count is 2. It seems a possible improvement can be made to `ChildRewriter`: - `Add` can track the index of the _last_ child expression that requires a `SpillStack` rewrite action - `EnsureDone` can use the information recorded by `Add` to avoid allocating temporaries _beyond_ the last child expression requiring spilling Optimized spilling code could result produce this instead: ``` ldc.i4.1 stloc.0 .try { ldarg.1 // x stloc.1 leave X } finally { endfinally } X: ldloc.1 // unrelated case of unnecessary local due to our emit stloc.2 // strategy and the lack of a stack optimizer, but ... ldloc.0 ldloc.2 // ... this could be ldloc.1 without a need for loc.2 add ldc.i4.2 add ldc.i4.3 add ret ``` 11857 area-System.ComponentModel Port System.ComponentModel.Composition (MEF1) to .NET Core With the additional APIs that will be available in .NET Standard 2.0, it may be possible to make System.ComponetModel.Composition (MEF1) available for .NET Core and .NET Standard 2.0.

I propose we add a new type that is immutable so it can have operators for easier usage. ### API Proposal Modelled based on `BitArray` [src](https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/BitArray.cs#L13)/[apisof.net](https://apisof.net/catalog/System.Collections.BitArray) and `ImmutableList` [src](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableList_1.cs#L19)/[apisof.net](https://apisof.net/catalog/System.Collections.Immutable.IImmutableList%3CT%3E) **Open questions:** - Should we add `Set`, `SetAll`, `Get` methods as `BitArray` has? - Should we add `IEnumerable` to `BitArray`? **Resolved questions:** - Should we add `public struct Enumerator GetEnumerator()` on `BitArray`? - Answer: No, there already is `public IEnumerable GetEnumerator()`, so we are stuck with boxing there. - Add shift methods and operators. - Answer: Done. ### 1st Part ```c# namespace System.Collections.Immutable { // NEW: BitArray has only ICollection, IEnumerable, not IEnumerable public struct ImmutableBitArray : IEnumerable { public ImmutableBitArray(int length);

The code is mostly taken from desktop and then cleaned up a bit stylistically. The only major code rewrite was removing hundreds of lines of complicated APM callback-based code and replacing it with a few core async methods. There's still plenty of more cleanup that can be done, but functionally this is sufficient. I also wrote a bunch of tests for it (~85% coverage), and added a few members to {Http}WebRequest in support of the WebClient implementation. I did not expose those {Http}WebRequest members in the contract, though; that will be done when dedicated time is put into finishing off the WebRequest surface area. Note that a suggestion had been made to rewrite WebClient directly on top of HttpClient. I declined to do so for several reasons, including because as-is it'll work with the other *WebRequest/Response objects as they're added to the implementation, and including because WebClient exposes several members that assume a WebRequest/Response-based implementation (e.g. GetWebRequest). I've put WebClient into System.Net.Requests as it does tie in closely with these requests, analagous to TcpClient with Sockets.

However, unless we plan to ship with such functionality stubbed out, I don't think we're going to want to keep this as a separate contract. The public surface area of ServicePointManager actually brings in / depends on WebRequest, which means that for WebRequest and friends to respect settings from ServicePointManager, ServicePointManager can't live in a contract above WebRequest. Instead, I think we should push all of these types down into System.Net.Requests, recognizing that these types are part of that compat model and used only with/for that model. We would be explicitly acknowledging that HttpClient would not respect any of the associated settings, as System.Net.Requests depends on System.Net.Http, not the other way around, and thus System.Net.Http wouldn't have access to ServicePointManager (other than through super hacky means like reflection). 11933 area-System.Net Add new test rids to System.Net.Mime projects Adds the two new test rids to the recently-added System.Net.Mime projects. 11935 area-Meta Where to find a complete list of NuGet packages for corporate NuGet server For corporations who block access to public feeds such as NuGet.org, they usually download packages and then host them on a private NuGet server. That approach works fine for a few years already. Now .NET Core development relies even more on NuGet.org, and it involves tons of packages (both managed and native), which makes it very difficult for any outsiders to generate a complete list of required packages from scratch. Thus, I'd like to ask if Microsoft can provide such a list (or at least show how such a list can be compiled from source code or any other public information). The necessary columns I can think of are below, File: netcore1.0.0.txt | Package name | version | | --- | --- | | System | 4.0.0 | ... File: netcore1.0.1.txt | Package name | version | | --- | --- | | System | 4.0.1 | ... Then we can write custom scripts to download the packages from NuGet.org and then deploy to private NuGet server. Of course, if Microsoft can provide such a script, it would be highly appreciated. 11940 area-System.Net Add new test rids to System.Net.WebClient project cc: @mellinoe 11943 area-System.IO "Directory.GetDirectories returns zero sub-directories with search pattern ""*."" on Unix" "On windows using search pattern ""*."" returns all the sub-directories but on Unix it returns zero sub-directories.

There doesn't seem to be any need to limit this stuff further. @ericstj - IPv4InterfaceStatistics returns identical information to IPInterfaceStatistics. This behavior is inherited from Windows. This is the reason we originally removed the API. - The Begin/EndGetUnicastAddresses methods are thin wrappers over the Task-based async method on Unix. The Task-based version is a thin wrapper over the sync version. .NET Native does not implement this. - Some of the functionality was already implemented in the Windows version, which is why it doesn't appear in the diff. For things that were not implemented already, I took the implementation directly from the sources for System.dll (.NET Framework). - The Unix versions of NetworkAvailabilityChanged are much less robust and reliable than the Win32 version, due to platform differences. The implementations are modeled somewhat after what Mono does in these cases. - The Linux version listens to additional ""Route Changed"" notifications on the rtnetlink socket we are using. When ""Route Changed"" socket events are received, we propagate them out to NetworkAvailabilityChanged events. We attempt to coalesce such socket events which occur within 150 milliseconds of each other; this is because the OS sends many events in quick succession in response to a single network change. This approach is borrowed from the Mono version. It is not extremely robust, and can result in duplicate events if the OS happens to send them to us more than 150 milliseconds apart. - The OSX version conservatively fires off NetworkAvailabilityChanged events whenever a network address changes, even if the overall availability has not really changed. Mono has a different approach here, but it does not seem to work. I have run my test program on mono, and neither NetworkAddressChanged nor NetworkAvailabilityChanged events are ever fired, except when initially subscribed to. Even in theory, the approach used there still does not handle false positives, duplicate notifications, etc. - Both of the Unix versions result in false positives. They do not filter potential events based on past state. So you may receive numerous events in succession which all indicate the same connectivity status. This is different from Windows where each event will indicate that the availability has flipped. - The .NET Native version of this library is already very crippled. I have implemented NetworkAvailabilityChanged in a similar manner to the Unix versions. It fires the event whenever a network address change is detected, with true information about the current network availability. Most of the other new methods are not implemented (PlatformNotSupportedException). - During testing of the above features, I identified a problem in the implementation of NetworkInterface.GetIsNetworkAvailable() on Unix platforms. This method is not supposed to consider Loopback or Tunnel interfaces. This was not a big problem on Linux (where I did the most testing) because Loopback interfaces often report their status as ""Unknown"" on Linux. However, the OSX machine I tested has a Loopback device with status ""Up"". I've excluded Loopback/Tunnel types from consideration in this function. @stephentoub , @CIPop , @davidsh cc: @karelz " 11958 area-System.Data System.Data.SqlClient.SqlConnection.ChangePassword not implemented It appears that the SqlConnection class does not have ChangePassword() as an available method.

Fixes #11973 11976 area-System.Collections SortedDictionary.First performance Getting the `First` element of a `SortedDictionary` causes allocation of a stack that is log sized in the number of elements in the dictionary. This can be done without any allocation. Currently, `First` is only an extension method for `SortedDictionary`. This means it builds an `Enumerator`, and then uses that to get the first element. The enumerator creates a stack to aid its traversal of the underlying RedBlack tree. This seems the correct thing for the enumerator to do, but in the context of getting the single first element it is very costly. There does not seem to be a sensible way to alter the enumerator to special case this use, without introducing conditionals and hence costs elsewhere. Would it be possible to make `First` a method of `SortedDictionary`, rather than an extension method, then it would be able to call `SortedSet.Min` directly? I am not familiar with the repurcussions of making an extension method into an actual method. Is there a way for this to break existing code, or not? I can submit a Pull Request if that is the right way forward. 11978 area-System.Net WinHttpHandler is allocating twice the required buffer for headers GetResponseHeaderCharBufferLength is calling into WinHttpQueryHeaders which returns the buffer size in bytes not C# char which is 16bit wide.

In fact, these optimizations are not even limited to LINQ; for example, making a copy of a Queue via ``` cs var queue = GetQueueOf(); var copy = new Queue(queue); ``` will be artificially slow, since [Queue's constructor](https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/Generic/Queue.cs#L56-L63) calls `EnumerableHelpers.ToArray`, which goes down a slow path if the input is not an ICollection. Similarly, [here](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Collections/Generic/List.cs#L705) is another such optimization in `List.InsertRange`. ## Proposal We should explicitly implement the `ICollection` interface on both of these classes. For any method that doesn't have very clear semantics, we can simply throw a `NotSupportedException` just like arrays do for certain `IList` methods. ``` cs namespace System.Collections.Generic { public class Stack : ICollection, IEnumerable, ICollection, IReadOnlyCollection { bool ICollection.IsReadOnly { get; } void ICollection.Add(T item); bool ICollection.Remove(T item); } public class Queue : ICollection, IEnumerable, ICollection, IReadOnlyCollection { bool ICollection.IsReadOnly { get; } void ICollection.Add(T item); bool ICollection.Remove(T item); } } ``` Some `ICollection` methods like `Count` and `CopyTo` are excluded since the collections already contain implementations of those methods. ### `Add` implementations `Add` should just call `Enqueue` for Queue, but it is somewhat vague for Stack (the caller is probably assuming that the item is being added to the _end_ of the collection). I suggest we throw a `NotSupportedException` rather than calling `Push`. @justinvp @terrajobst 11991 area-System.Net Expect: 100-Continue header auto-added on HttpClient request on Linux Hi, we have an issue whereby an 'Expect: 100-Continue' header is being automatically added to all HttpClient POST/PUT requests when our .NET Core web api service is deployed to a linux environment (specifically Ubuntu 14.04/16.04). The header is not added when the service is run in a windows environment, both from within Visual Studio and directly in the console using dotnet run. Logging of the headers of the HttpClient in the service prior to calling SendAsync shows that the Expect header is not set, however logging of the HTTP requests on the server using tcpdump show that it is being set. I have tried to remove the headers via, client.DefaultRequestHeaders.ExpectContinue = false; and client.DefaultRequestHeaders.Expect.Clear(); however they are still added. Our issue is that our service must pass through a squid proxy whose version does not support the Expect header. We do not have control over this proxy and it's unlikely we will be able to update the version in the near future. Cheers, Luke 11992 area-System.Linq Expression trees for half-lifted conversion operators do not work "There is a change in the way that Roslyn handles expression trees versus the native compiler. For the sample program below, the native compiler generates incorrect code for the initialization of ef2. The initialization executes without problems, building an incorrect expression tree. But compiling and running the resulting expression tree with a null argument fails (an exception is thrown at the line marked (2)). Roslyn attempts to produce the correct expression tree for ef2. However, a bug in the expression tree libraries (529431 in the previous tracking system) causes an exception to be thrown when initializing ef2. The program cannot even run as far as the code generated by the native compiler. Alex has marked the expression tree library bug as one that will not be fixed in the release for which the bug was filed, so I'm opening the issure here in hopes it will not get lost. ``` cs using System; using System.Linq.Expressions; struct Struct1 { } struct Struct2 { public static explicit operator Struct2?(Struct1 s2) { return new Struct2(); } } public class Test { static void Main() { Func f1 = (x) => (Struct2?)x; f1(null); Expression> ef2 = (x) => (Struct2?)x; // (1) Roslyn: fails at runtime Func f2 = ef2.Compile(); f2(null); // (2) Native: fails at runtime } } ``` --- Here is a take on this from another internal thread Consider a user-defined conversion from S1 to S2? The compiler considers this to give rise to a lifted conversion from S1? To S2? There are three bugs here 1. This rule is missing from the C# language specification 2. The native C# compiler generates different-behaving code for this lifted conversion directly compared to this conversion in a compiled expression tree 3. The expression tree API has no way to express this half-lifted conversion. ``` cs using System; using System.Linq; using System.Linq.Expressions; using System.Reflection; struct Struct1 { } struct Struct2 { public static implicit operator Struct2?(Struct1 s2) { return new Struct2(); } } static class NullableExtensions { public static string ToStringOrNull(this T? n) where T : struct { return n.HasValue ? n.Value.ToString() : ""null""; } } public class Test { static void Main() { // Bug related to Roslyn bug 12706 // The native compiler generates different-behaving code for a lambda // expression, and an expression tree for that lambda expression, compiled. Struct1? n = null; // the following prints ""null"" Func f1 = x => x; Console.WriteLine(""first test""); Console.WriteLine(f1(n).ToStringOrNull()); // the following throws System.InvalidOperationException: Nullable object must have a value. Expression> testExpr = x => x; Func f2 = testExpr.Compile(); Console.WriteLine(""second test""); Console.WriteLine(f2(n).ToStringOrNull()); } static void Test2() { // this is how one would like to generate code for the lambda expression, // but a bug in the expression tree library prevents this from working. var x = Expression.Parameter(typeof(Struct1?), ""x""); MethodInfo opImplicit = typeof(Struct2).GetMethod(""op_Implicit""); // the following throws System.InvalidOperationException: The operands for operator 'Convert' do not match the parameters of method 'op_Implicit'. var result = Expression.Convert(x, typeof(Struct2?), opImplicit); Expression> testExpr = Expression.Lambda>(result, x); } } ``` " 11994 area-System.Linq VariableBinder in lambda compiler does not analyze CatchBlock.Filter "Repro: ``` csharp var e = Expression.Lambda( Expression.TryCatch( Expression.Empty(), Expression.Catch( Expression.Parameter(typeof(Expression), ""ex""), Expression.Empty(), Expression.Parameter(typeof(bool), ""???"") ) ) ); e.Compile(); ``` This gets as far as `ILGen` (failing there for DynamicMethod emit due to a limitation in System.Reflection.Emit that's tracked to be lifted at some point, see https://github.com/dotnet/corefx/issues/3838).

area-System.Net Move recently added WebClient tests to outerloop I saw these fail with connectivity issues today; moving to outer loop with other such networking tests. 12032 area-System.Collections Would it be possible to shrink the field size of LinkedList? Noticed that 0e62a60 added a new field to `LinkedList`, `_siInfo`, for serialization. Since that and SyncRoot are rarely used, perhaps they can be combined into a `StrongBox` to shrink the size of LinkedList. 12033 area-System.Collections Enumerable.Contains ICollection optimization should go in a different overload Here's the current source for `Enumerable.Contains`: ``` cs public static bool Contains(this IEnumerable source, TSource value) { ICollection collection = source as ICollection; if (collection != null) { return collection.Contains(value); } return Contains(source, value, null); } public static bool Contains(this IEnumerable source, TSource value, IEqualityComparer comparer) { if (comparer == null) { comparer = EqualityComparer.Default; } if (source == null) { throw Error.ArgumentNull(nameof(source)); } foreach (TSource element in source) { if (comparer.Equals(element, value)) { return true; } } return false; } ``` as you can see, in the comparer-less overload, it checks if the source implements ICollection first and then calls `Contains` on that collection if so. However, this is not done in the overload that doesn't accept a comparer. We may want to consider instead checking for ref equality to `EqualityComaprer.Default` in the other overload, and then applying the ICollection optimizaion. This will potentially make code that calls `Contains` with a comparer, i.e. a custom data structure that accepts a comparer in its constructor, faster. 12034 area-Meta Create System.Spatial types for SQL-Independent geography code It's been about 8 years since Spatial support was added to SQL Server. At the time, .NET was not as far along as it is today, and was not open source. The team created a SQL-dependent version of the Geography classes, which has created [situations this this at hundreds of companies](http://stackoverflow.com/questions/27343024/using-sql-server-geography-in-c-sharp-entities-without-referencing-entity-framew). Now that we have .NET Core, Roslyn, and a bunch of other new, amazing technologies in .NET... it might be time to give it another go and see if we can create a vanilla set of `System.Spatial` types that the Entity Framework, OData, and other spatial libraries can inherit from. Since DbGeography types [aren't even really on the EFCore schedule yet](https://github.com/aspnet/EntityFramework/wiki/Roadmap), this is the perfect time to get something spun up so that EFCore can leverage these types when the time comes. 12035 area-System.IO Add negative tests for FileStream Begin/End "Adds negative tests for Begin/End, removes unnecessary block for `\\.\` paths.

It was only introduced in Windows 10. However, it was later backported as a serving fix to both Windows 8.1 (Windows Server 2012 R2) and Windows 8 (Windows Server 2012). It is not possible to detect in the CI tests if a servicing patch is installed. So, this PR adjusts the capability detection to return a null value (instead of true or false) to indicate this uncertainty and thus the tests are skipped in that case. Fixes #11088 12042 area-System.Linq Optimize Enumerable.Cast calls followed by ToArray or ToList, refactor Count This PR contains 3 changes: - Segregate parts of `Enumerable.Count` so it is possible to call `Count` from an IIListProvider w/o going into an infinite loop. This is useful for iterators (like this one) where we can optimize `ToArray` or `ToList` but not `Count`. - Optimize the iterator returned by `Cast` for non-generic ICollections; in `ToArray` and `ToList` we can preallocate an array before enumerating the items. Common BCL containers such as List/Queue/Array/etc. implement the non-generic interface, so the optimizations should benefit a lot of code. - GetCount can't be optimized since just returning the `.Count` of the source collection wouldn't actually verify that all of the elements in it were of type TResult. This isn't a problem for `ToArray` / `ToList` however, since we have to go through the entire collection anyway. - Add extensive testing for the changes, including regression tests to make sure that `Skip`, `ElementAt`, `Last`, etc. aren't optimized. @stephentoub, @VSadov, @JonHanna 12046 area-System.Security Add remaining missing members of System.Security namespace (not child namespaces) Tests are not passing at all on my box yet due to unrelated errors which I will follow up with offline if they don't occur on CI.

I saw `TypeForwardedToAttribute` for binary capability. - Some packages set a reference to assembly in GAC. This is by using `frameworkAssembly` element of nuget. - Some packages **do install an assembly**, but it already exists in the full Framework, such as `System.IO.Compression` and `System.Net.Http`. Why can't these be treated as well as the above-mentioned type? And another question for type resolving: IL records the definition assembly for every type. If a type is moved into another assembly, a `TypeForwardedToAttrubute` can be used for binary capability. But for some assemblies, for example `System.ObjectModel`, I haven't see it in GAC. How can `[System.ObjectModel]System.ComponentModel.INotifyPropertyChanged` be resolved to `[System]System.ComponentModel.INotifyPropertyChanged`? **Edited**: - For `System.IO.Compression`, I see a `runtime` folder in the package. It seems that assembly installed to `net46` is the win runtime. But why only install a GAC assembly in `net45`? - For `System.Console`, I see an assembly full of `TypeForwardedToAttrubute`.

Additionally, if source implements `IReadOnlyList` we can avoid the enumerator allocation and make only 1 as opposed to 2 virtual calls per iteration. I do not think we should optimize for read-only collections in other parts of the LINQ codebase, since 1) it would add a lot more complexity and 2) casting to variant interfaces is slow (dotnet/coreclr#603), so enumerables that do not implement these interfaces will pay. However, this particular case may be worthwhile, since it is such a hot codepath and the 2x virtual method calls per iteration will make the tradeoff immeasurable for larger lazy enumerables. This should definitely be considered once the related CoreCLR issue is fixed. This will benefit collections like `Stack` and `Queue` which do not implement `ICollection`.

For our official outerloop runs, we could require that they run, and thus require that the package be pre-installed (like all our other dependencies). 12114 area-Meta Restoring Microsoft.NETCore.App 1.1.0--preview1-001069-00 produces downgrade warnings - Multiple versions of the same package? ``` warn : Detected package downgrade: runtime.native.System.Security.Cryptography.OpenSsl from 4.1.1-preview1-24527-03 to 4.0.1-preview1-24527-03 warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> System.Net.Security (>= 4.3.0-preview1-24527-03) -> System.Runtime.Extensions (>= 4.1.0) -> runtime.unix.System.Runtime.Extensions (>= 4.3.0-preview1-24527-03) -> runtime.native.System.Security.Cryptography.OpenSsl (>= 4.1.1-preview1-24527-03) warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> System.Net.Security (>= 4.3.0-preview1-24527-03) -> runtime.native.System.Security.Cryptography.OpenSsl (>= 4.0.1-preview1-24527-03) ``` - Incorrect version ``` warn : Detected package downgrade: Microsoft.NETCore.DotNetHostResolver from 1.2.0-beta-000984-00 to 1.1.0-preview1-001069-00 warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostPolicy (>= 1.1.0-preview1-001069-00) -> runtime.win7-x64.Microsoft.NETCore.DotNetHostPolicy (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostResolver (>= 1.2.0-beta-000984-00) warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostPolicy (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostResolver (>= 1.1.0-preview1-001069-00) warn : Detected package downgrade: Microsoft.NETCore.DotNetHost from 1.2.0-beta-000984-00 to 1.1.0-preview1-001069-00 warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostPolicy (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostResolver (>= 1.1.0-preview1-001069-00) -> runtime.win7-x64.Microsoft.NETCore.DotNetHostResolver (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHost (>= 1.2.0-beta-000984-00) warn : restore-projects (>= 1.0.0) -> Microsoft.NETCore.App (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostPolicy (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHostResolver (>= 1.1.0-preview1-001069-00) -> Microsoft.NETCore.DotNetHost (>= 1.1.0-preview1-001069-00) ``` 12115 area-System.Runtime Helpers for structural equality and comparison "There are quite a few types that implement `IStructuralEquatable` and `IStructuralComparable` in the framework now - most notably, arrays and tuples, and hopefully more to come (collections?). Unfortunately, using them is unnecessarily verbose, because implementations of these are usually explicit (presumably to avoid overloading `Object.Equals`). So to compare two tuples or arrays `a` and `b`, you need to do something like this: ``` cs ((IStructuralEquatable)a).Equals((IStructuralEquatable)b, comparer); ``` Needless to say, this is also not particularly discoverable. Case in point: search for e.g. ""C# compare arrays"" on StackOverflow, and note how many duplicate questions there are, and how few of them have responses mentioning `IStructuralEquatable` at all. One particular answer [here](http://stackoverflow.com/a/3234749/111335) suggests adding a couple of helper methods: ``` cs static class StructuralExtensions { public static bool StructuralEquals(this T a, T b) where T : IStructuralEquatable { return a.Equals(b, StructuralComparisons.StructuralEqualityComparer); } public static int StructuralCompare(this T a, T b) where T : IStructuralComparable { return a.CompareTo(b, StructuralComparisons.StructuralComparer); } } ``` which then allows doing: ``` a.StructuralEquals(b); ``` where applicable. Should this, perhaps, just be a part of the standard library somewhere in `System`? For anyone using VS, or a similar IDE with code completion, this would make the methods appear as members on all types that support them, even when they implement the interfaces explicitly, and thus easy to discover. (Note that there's a separate question here on whether the default comparers are appropriate, or whether the API should always require an explicit comparer argument. But that is orthogonal to whether such helpers should be readily available out of the box.) " 12121 area-System.Net Fix Uri handling of unknown schemes Somehow this expression got transposed in corefx; it should be `end - startOtherHost` rather than `startOtherHost - end` (as can be seen in the previous section of code, end will always be >= startOtherHost).

It would have exactly the same semantics as List, except it would be a mutable struct so no allocation for the list itself. Additionally, since this would be an internal type we could make other micro-optimizations e.g. `_syncRoot` field, `_version` only exists in debug (which also means `MoveNext` might be inlined), bounds checks in indexer are Debug.Asserts, etc. This would help in places such as [here](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/EnumerableHelpers.cs#L135), where we want a dynamically-grown array and don't want to manually write the resizing logic, but really want to minimize allocations. 12182 area-System.Collections Could SortedSet.InOrderTreeWalk use recursion instead of allocating? `SortedSet.InOrderTreeWalk` currently uses a stack on which the nodes to walk are pushed/popped: https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/Generic/SortedSet.cs#L234 It looks like it would be possible to implement this recursively instead, i.e. `InOrderTreeWalk(left); action(current); InOrderTreeWalk(right)` and eliminate the Stack allocation. 12183 area-System.Numerics Updating the 'System.Runtime.Extensions' contracts to include the new single-precision Math APIs.

After ShutdownAsync has been called, the write portion of the full-duplex channel is closed and the channel becomes read-only. The handshake is completed when no more bytes can be read from the SslStream (Read APIs return 0.) ## New API Usage The following code shows usage of the new API as well as new server-side behavior. This as well as tests demonstrating the new behavior to support 7.2.2. during TLS Handshake is available in `SslStreamAlertsTest.cs`, #11489. ``` C# var handshake = new Task[2]; handshake[0] = server.AuthenticateAsServerAsync(certificate); handshake[1] = client.AuthenticateAsClientAsync(certificate.GetNameInfo(X509NameType.SimpleName, false)); await Task.WhenAll(handshake).TimeoutAfter(TestConfiguration.PassingTestTimeoutMilliseconds); var readBuffer = new byte[1024]; await server.ShutdownAsync(); int bytesRead = await client.ReadAsync(readBuffer, 0, readBuffer.Length); // close_notify received by the client. Assert.Equal(0, bytesRead); await client.ShutdownAsync(); bytesRead = await server.ReadAsync(readBuffer, 0, readBuffer.Length); // close_notify received by the server. Assert.Equal(0, bytesRead); ``` ## Pull Requests WIP (tooling/WIP) API change: #11265.

I have created a little demo app to do this. It repro's on both `netcoreapp1.0` and `net45`: [processredirect.zip](https://github.com/dotnet/corefx/files/501954/processredirect.zip). Just use `dotnet run` to try it out. That being said, you can capture stdout by using `Process.StandardOutput` (which is a `StreamReader`). However to consume this asynchronously and safely you need to use background threads/tasks. In other words: | stdout capture method | using infinite timeout | is flaky | | --- | --- | --- | | `StandardOutput` `StreamReader` | yes | no | | `StandardOutput` `StreamReader` | no | no | | `OutputDataReceived` event | yes | no | | `OutputDataReceived` event | no | **yes** | I think this a problem because it's pretty easy to step into this pitfall. Using the events to capture output is very convenient since you don't have to worry about making background threads or tasks. Also, the internet recommends this method: - http://stackoverflow.com/questions/285760/how-to-spawn-a-process-and-capture-its-stdout-in-net - https://msdn.microsoft.com/en-us/library/system.diagnostics.process.beginoutputreadline(v=vs.110).aspx I have only tried this on Windows, .NET Framework 4.5 and .NET Core (`netcoreapp1.0`). Also, all of this information is related to stdout, but I imagine stderr has the same problem.

Initial iteration on pretty printing of expression interpreter instruction stream in order to perform asserts in test code. The functionality leverages some of the existing `DebugView` printing for instructions that was already present in the library. It adds an internal `DebugView` to the `LightLambda` type, which can be used to retrieve the instructions in a pretty printed form. Note the approach differs a bit from the IL visualizer for the expression compiler, where we have to peek into implementation details of `DynamicMethod` etc. While we could also use private reflection here, it seems much more pragmatic to add the printing support in the runtime library (adding to already existing support for `DebugView`-like functionality) and limit the test/product boundary contract to retrieving just the one `DebugView` property. 12279 area-Infrastructure Updating CoreClr dependencies to servicing-24601-01 /cc @dotnet/corefx-contrib 12281 area-System.Collections HashSetEqualityComparer is not marked as Serializable On .NET 4.6 HashSetEqualityComparer is marked as Serializable. https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/Generic/HashSetEqualityComparer.cs compared to: http://referencesource.microsoft.com/#System.Core/System/Collections/Generic/HashSetEqualityComparer.cs,b81a34218101efe7,references Thank you. 12282 area-System.Net HttpWebRequest internally throws 2 exceptions "Create a .NET Core 1.0.1 console project with this line of code: **HttpWebRequest.CreateHttp(""https://www.google.ca/"").GetResponseAsync().Wait();** Execute it and examine the output window: Exception thrown: 'System.PlatformNotSupportedException' in System.Net.Requests.dll Exception thrown: 'System.ArgumentNullException' in System.Private.CoreLib.ni.dll **This occurs on every call, which cannot be good for performance.** The PlatformNotSupportedException can be avoided by setting the HttpWebRequest object .Proxy = null, or setting HttpWebRequest.DefaultWebProxy = null; I have not yet found a way to avoid the ArgumentNullException (some SafeHandle cannot be null) Stack trace top 2 items show: System.Private.CoreLib.ni.dll!System.StubHelpers.StubHelpers.SafeHandleAddRef(System.Runtime.InteropServices.SafeHandle pHandle, ref bool success) System.Net.Http.dll!System.Net.Http.WinHttpHandler.StartRequest(object obj) " 12283 area-System.Linq Should we check source.Count every time SelectListPartitionIterator.MoveNext is called? Currently, we check `source.Count` every time we iterate through a `SelectListPartitionIterator`: https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Select.cs#L713. Presumably, this is so that if we update the `IList` in question while we are iterating the sequence returned by Skip/Take, we will still run the selector on the elements added. For example: ``` cs List ids = GetCustomerIds(); foreach (var c in ids.Select(i => Customer.From(i)).Skip(5)) { if (c.HasChildren) { ids.AddRange(c.ChildrenIds); // we will pass over these in the foreach loop } } ``` However, this will do a dead stop the moment we modify the source list: ``` cs foreach (int id in ids.Select(i => Customer.From(i))) // no .Skip(5) { if (c.HasChildren) { // Instead of indexing into the list, we're getting it's enumerator here // AddRange mutates ids._version, which causes the enumerator's MoveNext to return false ids.AddRange(c.ChildrenIds); } } ``` My question is, should adding stuff to the list while enumerating from `Skip` be a supported scenario? It seems like [during RC1](https://github.com/dotnet/corefx/blob/release/1.0.0-rc1/src/System.Linq/src/System/Linq/Enumerable.cs#L832-L848) we would just stop during `Select(...).Take` if the source was modified during enumeration, so it's very unlikely people are going to depend on this change. Perhaps we should just cache the count when the first `MoveNext` is called, e.g. ``` cs private int _count; public override bool MoveNext() { switch (_state) { case 1: _count = _source.Count; _state = 2; goto case 2; case 2: if (_index <= _maxIndexInclusive && _index < _count) { ... } } } ``` This will still not match the original behavior of stopping once the source is modified. However, it will be faster than the current behavior, which enumerates the entire list taking into account any modifications that have occurred even after the first `MoveNext`, since we are now caching `_count`. (Additionally, it will still preserve behavior in cases where the list is mutated after `Skip` is called, but before it's actually iterated.) @stephentoub, @VSadov, @JonHanna 12287 area-System.Collections Add ArrayBuilder struct, delete LowLevelList This commit adds a new, lightweight `ValueList` type that has the same semantics as `List`, except it's a struct so there's no heap allocation for the list. I've used it in `Enumerable.ToArray` to avoid an allocation as well as `Uri.Segments`; I'm sure there are other places it can be used as well, so I added it in Common. All of the argument validation is done as Debug.Asserts so it's easier for the JIT to do inlining. Additionally, there is no `_version` field so `MoveNext` can be inlined. (Unfortunately there is not a way to check this even in debug, since `ValueList` is a struct so we can't pass a reference to it to the enumerator.) The type implements most of the commonly-used methods of `List` (Add, indexer, Count, etc). as well as a few other methods: - `AsArray()` - returns the underlying backing store for the list, which may have some trailing nulls at the end. - `AsArray(out int count)` - returns the underlying backing store for the list, and also writes to an out param indicating how many elements are represented by the array. - `AsOrToArray()` - returns the backing array if it can just hold all of the items in the list, or else copies the relevant elements to a new array. I'm temporarily marking no-merge, since there's still work do be done (adding Common tests, xml docs, etc.). cc @stephentoub, @justinvp; what do you think of adding this type? It's an extra hundred lines or so, but in exchange we get to delete LowLevelList which is ~600.

For example, I once messed up `Path.Combine` so that the runner had problems finding the test assembly, so I had to mentally go through the code and see what was wrong. Another time, I messed up `Buffer.MemoryCopy`, but _only_ for unaligned data, so I had no idea what was wrong when I pasted the code into a console application. I ended up having to put `Console.WriteLine` in the MemoryCopy code (which was complex because WriteLine uses that function) to see what was going on. It would be nice if the assemblies the test runner runs on are separated from the versions that are being tested, so it's easier to change commonly-used functions. cc @hughbe 12331 area-System.Net Consider removing netcore50 from the list of TFMs actively targeted by the System.Net.Sockets build "See discussion here: https://github.com/dotnet/corefx/pull/12249#pullrequestreview-2423298 Should we remove the netcore50 build of System.Net.Sockets?

In some cases, `KeyChar` has the correct key, but `Modifiers` is still `0`, resulting in incorrectly assuming Ctrl was not down and e.g. inserting a `!` instead of doing whatever action `Ctrl+!` was bound to.

Is this still true or is an exception thrown instead? Given how many changes to reflection are part of .NET Core, there's no way to know other than trial or error or looking through the source code. Both of these options do poorly for productivity. The lack of such basic information in the XML comments that drive the IntelliSense and F12 metadata is a major omission. More concerning is the release process that allowed .NET Core to be labeled as version 1.0 fully stable, production ready, without essential documentation. A systematic review and backfilling of missing documentation would save a world of developers untold time and be well worth the effort. 12345 area-Infrastructure Improve sync time with a global test-runtime project.json restore upfront. This change is to improve the time taken by sync.cmd. It introduces the following changes. - Unifying all the test project.json's into a common project.json for the test build being consumed. - Removing test project.json's from the test dir and the test csproj, instead consuming the global one which is now in test-runtime. - Restoring this test-runtime project.json upfront as a part of both build and sync. There is only one test project.json now so as to avoid download contention withing the nuget restore processes while restoring multiple project.json's (which eats up double the raw download time of the packages). A singular project.json also removes all the I/O operations of generating multiple test lock files. (75% of the restore step is just in generating and walking through the lockfiles, IsRestoreRequired is a great way to avoid rerun cost for projects that still require their test project.json.) /cc @weshaggard @ericstj @markwilkie 12346 area-System.IO Bring StreamWriter/Reader to CoreFX, add path constructors - Exposes StreamWriter and StreamReader from CoreFX instead of mscorlib - Adds the string constructors that take a path to a file to read/write/append - Because of the FileStream dependency, Reflection is used in a separate internal helper class to attain access to File.Open. - Adds tests for the string constructors - Note: StreamReader.ReadAsyncInternal isn't overriding the TextReader parent when building for netstandard1.7 because TextReader is still contained within mscorlib and it is in an internal method. replaces https://github.com/dotnet/corefx/pull/12101 resolves https://github.com/dotnet/corefx/issues/12124 @stephentoub 12347 area-System.Net Port rest of HttpRequest and HttpWebResponse -Mostly easly ones which has direct equivalent in underlying HttpClientHandler -Major one which throw PNSE is ContinueDelegate , probably there's an easy way to do this. -Need to add more test , i haven't found any existing test for 509 certificates 12349 area-System.IO Add Begin/End async operations to System.IO.Pipes ``` - M:System.IO.Pipes.NamedPipeServerStream.BeginWaitForConnection(System.AsyncCallback,System.Object) - M:System.IO.Pipes.NamedPipeServerStream.EndWaitForConnection(System.IAsyncResult) - M:System.IO.Pipes.PipeStream.BeginRead(System.Byte[],System.Int32,System.Int32,System.AsyncCallback,System.Object) - M:System.IO.Pipes.PipeStream.BeginWrite(System.Byte[],System.Int32,System.Int32,System.AsyncCallback,System.Object) - M:System.IO.Pipes.PipeStream.EndRead(System.IAsyncResult) - M:System.IO.Pipes.PipeStream.EndWrite(System.IAsyncResult) ``` split from https://github.com/dotnet/corefx/issues/12197 12350 area-System.Reflection Add unit test for issue #7346 (custom attribute constructor crash on null array of enums) Just need to wait for the fix in coreclr to propagate over to corefx. https://github.com/dotnet/coreclr/issues/7346 12351 area-System.Runtime Add System.SystemException derivations Addresses issue https://github.com/dotnet/corefx/issues/12198 Since SystemException is only supported in netstandard1.7, I upgraded those contracts being touched here to netstandard1.7 as well. cc: @danmosemsft @weshaggard @ericstj @joperezr 12352 area-System.Net HttpContentMultipartExtensions in .NET Core The [`HttpContentMultipartExtensions`](https://msdn.microsoft.com/en-us/library/hh835439%28v=vs.108%29.aspx) were available in .NET Framework to parse multipart http responses.

That change is because our official builds expect each native platform build to be producing packages. If a native platform build doesn't produce any packages for publishing to Azure, then it gets reported as an error and fails the build. The change below skips the ""UploadToAzure"" step if the build didn't produce any packages. Two alternative solutions I considered: - Making the fix in BuildTools, but this requires a buildtools update and I didn't want to gate on that (i'm not certain that we have a good story for buildtools servicing changes for release/1.0.0). - Switch the official build step to non-blocking. An alternative would be to switch the ""publish-packages"" step of the build definition to non-blocking, but that has the potential to hide a real publishing error which we wouldn't catch until much later (or as another servicing fix).

This change updates SqlClient to support working with CLR UDTs as binary data. The SqlClient API to work with UDTs as binary already exists in the full .NET Framework. This change just unblocks the API on .NET Core. The SqlClient surface area is not changed. The following SqlDataReader methods can be used to retrieve as UDT as binary: - SqlDataReader.GetSqlBytes() - SqlDataReader.GetStream() - SqlDataReader.GetBytes() With this change, retrieving a CLR UDT instance is still not supported by SqlClient. The following SqlClient APIs to retrieve a CLR UDT instance have been updated to throw a PlatformNotSupported exception: - SqlDataReader[] get property indexer - SqlDataReader.GetValue() - SqlDataReader.GetValues() - SqlDataReader.GetSqlValue() - SqlDataReader.GetSqlValues() - SqlDataReader.GetFieldValue() - SqlDataReader.GetFieldValueAsync() - SqlDataReader.GetProviderSpecificFieldType() - SqlDataReader.GetProviderSpecificValue() - SqlDataReader.GetProviderSpecificValues() - SqlCommand.ExecuteScalar() For result set metadata obtained by calling SqlDataReader.GetColumnSchema(), we now populate the following properties for CLR UDTs: - Populate the DbColumn.UdtAssemblyQualifiedName property - Populate the DbColumn.DataType property with a Byte[] type Using a Byte[] for DbColumn.DataType has interesting forward compat implications. Ideally, we'd return the Type for the underlying UDT. Since that's not possible, I feel returning a Byte[] is the best compromise as it describes how to work with the CLR UDT as binary data. If/when .NET Core ever supports CLR UDTs, we'd have to think about the impact of changing DbColumn.DataType to return the CLR UDT type. 12372 area-System.ComponentModel Two ComponentModel tests fail after updating dependencies http://dotnet-ci.cloudapp.net/job/dotnet_corefx/job/master/job/windows_nt_debug_prtest/1099/ ``` System.ComponentModel.Tests.PropertyDescriptorTests.CopyConstructorAddsAttribute [FAIL] System.NullReferenceException : Object reference not set to an instance of an object.

Changes from Desktop implementation: - SmtpConnection uses TcpClient instead of ServicePointManager. - SslStream instead of internal TlsStream. - Negotiate, NTLM, Digest authentication protocols not ported due to dependency on internal NTAuthentication type. Authentication currently happens uses plain text login, SSL connections need to be used. - TcpClient connections are not pooled. - Getting mail settings from `web.config` files is not supported, as netstandard2.0 doesn't expose the `System.Net.Configuration` apis. - Sending mail to IIS pickup directory currently throws `NotSupportedException`. Desktop uses COM types for this API, investigation on partially supporting this feature on Windows is pending. Notes: - Tests will be added separately. - Please review `SmtpConnection.cs` and `TlsStream.cs` files for correctness, they have changed functionally from Desktop code. - The TcpClient connect does not have `Connect()`, `BeginConnect()` and `EndConnect()` in .NET Core contract yet, once that's available, the SendAsync should use the async connect methods. - Update: Added now Did a test locally using the `SmtpClient.Send()` and `SmtpClient.SendAsync()` , was able to successfully send emails to google smpt server with tls authentication. cc @stephentoub @ericeil @CIPop @davidsh @geoffkizer @tijoytom @karelz 12419 area-Infrastructure Updating CoreFx dependencies to servicing-24606-05 /cc @dotnet/corefx-contrib 12421 area-System.Runtime Proposal: Support for building query string collection in UriBuilder "## Background Currently UriBuilder class does not have a constructor / method to build query string parameters values. Please note that I would like to implement this feature in the existing UriBuilder class. ## Proposed API **Open questions** - How often is this kind of functionality hand-written by apps? (ideally some links to popular GitHub projects, or links to StackOverflow / blog post samples = real-world examples) - In general it looks useful, but it is always good to collect more data. - What is difference between `IEnumerable>` and `IDictionary` overloads?Do they have different usage patterns? (real-world examples ideally) ```diff public class UriBuilder { public UriQueryStringBuilder(); public UriQueryStringBuilder(string schemeName, string hostName, string path); ... + public UriQueryStringBuilder(string schemeName, string hostName, string path, IEnumerable> queryParameters); + public UriQueryStringBuilder(string schemeName, string hostName, string path, IDictionary queryParameters); + public IDictionary QueryParameters {get;} + public void AddQueryParameter(string key, string value); } ``` ### Usage ```c# //1.

Part of having a class like this is that the Jit can target these methods class for intrinsics, similar to what was done for `Vector`. There is still some open discussion as to what the shape of this API should be, and even the class name. #### Class Name There are several class names being thrown around and none are particularly winning everyone over. - Bits - BitOperations or BitOps - BitUtility - BitTwiddler - BitView (see the next section) #### Two Classes? @benaadams, correctly notes that there seems to be two different APIs here. A low level view allowing you to manipulate a numeric type to extract or inject a bit (like a bit vector), byte, short, or int value. These methods are the equivalent of the following but safer (and possibly faster) ```csharp public static unsafe int ExtractInt(ulong u,int pos)=>((int*)&u)[pos]; public static unsafe ulong InjectInt(ulong u, int pos, int toSet) { ((int*)&u)[pos] = toSet; return u; } ``` And another set of utility exposing methods for treating an integer register type like a unit of data allowing you to manipulate it or introspect it. Does it make sense to keep these APIs in one class? #### Method Names Another point of contention. What should we call these methods? For the ""view"" members, there is some dislike of the naming convention of `Get`/`Set` even though there is prior art like `BitVector32` & `SqlDataRecord`. Everyone seems to like `Read`/`Write` more, but while `Read` is fine. `Write` isn't neccessarily the operation being done. I'm still looking for some verbiage to note that this really takes a value, modifies it a bit (no pun intended), and spit out a new one. PopCount/HammingWeight/ CountSetBits - We can't decide on this name. I personally like `PopCount` as it is a well known name for the algorithm. However, for someone who does not CPU intrinsics or bit tricks this name might mean nothing to you. the .net api is split where common or well known algorithms are simply called that (e.g. `Rijndael`) and sometimes descriptive for new users. I think that this class in general is fairly low-level so even a novice should be expected to do a quick google search in the subject area. And even naming the methods as actions (e.g. `CountTrailingZeroes`) or properties (e.g. `TrailingZeroesCount`). #### Hardware Acceleration / Detection @benaadams, suggested adding a simple flag to determine if the class has hardware acceleration. I personally suggest going a step further and adding an `enum` to describe which methods are accelerated (not in the PoC). Unfortunately, the `enum` based approach does raise the question if the jit could do branch elimination on a comparison like the following if it could replace `AcceleratedOperations` as a runtime constant. (unknown) ```csharp // if (Bits.AcceleratedOperations == BitOps.PopCount){ // use popcount } else{ // work around it? } ``` I admittedly question what you would do differently if it isn't accelerated. This isn't like `Vector` where you might switch to a different approach and use `ulong` like smaller vectors. The methods should be pretty good solutions to these problems and outside of switching to some native code I don't see us doing better. Methods that could be accelerated (in AMD64 at least):: `PopCount` => `POPCNT` `RotateRight` => `ROR` (already accelerated!) `RotateLeft` => `ROL` (already accelerated!) `CountLeadingZeroes` => `LZCNT` (in ABM compliant hardware) or (`BSR` followed by xor 63) `CountTrailingZeroes` => `TZCNT` / `BSF` `ReadBit` => `BT` `WriteBit` => `BTS`/`BTC` (maybe?) `ReadByte`/`ReadInt16`/`ReadInt32` => `BEXTR` (possibly) Updated spec: ``` csharp public static class Bits{ public static int PopCount(ulong value); public static int PopCount(long value); public static int PopCount(uint value); public static int PopCount(int value); public static ulong RotateRight(ulong value, int offset); public static uint RotateRight(uint value, int offset); public static ulong RotateLeft(ulong value, int offset); public static uint RotateLeft(uint value, int offset); public static int CountLeadingZeros(ulong value); public static int CountLeadingZeros(long value); public static int CountLeadingZeros(uint value); public static int CountLeadingZeros(int value); public static int CountTrailingZeroes(ulong value); public static int CountTrailingZeroes(long value); public static int CountTrailingZeroes(uint value); public static int CountTrailingZeroes(int value); public static bool ReadBit(ulong value, int offset); public static bool ReadBit(long value, int offset); public static bool ReadBit(uint value, int offset); public static bool ReadBit(int value, int offset); public static ulong WriteBit(ulong value, int offset, bool toSet); public static long WriteBit(long value, int offset, bool toSet); public static uint WriteBit(uint value, int offset, bool toSet); public static int WriteBit(int value, int offset, bool toSet); public static byte ReadByte(ulong value, int offset); public static byte ReadByte(long value, int offset); public static byte ReadByte(uint value, int offset); public static byte ReadByte(int value, int offset); public static short ReadInt16(ulong value, int offset); public static short ReadInt16(long value, int offset); public static short ReadInt16(uint value, int offset); public static short ReadInt16(int value, int offset); public static int ReadInt32(ulong value, int offset); public static int ReadInt32(long value, int offset); public static ulong WriteByte(ulong value, int offset, byte toSet); public static long WriteByte(long value, int offset, byte toSet); public static uint WriteByte(uint value, int offset, byte toSet); public static int WriteByte(int value, int offset, byte toSet); public static ulong WriteInt16(ulong value, int offset, short toSet); public static long WriteInt16(long value, int offset, short toSet); public static uint WriteInt16(uint value, int offset, short toSet); public static int WriteInt16(int value, int offset, short toSet); public static ulong WriteInt32(ulong value, int position, int toSet); public static long WriteInt32(long value, int position, int toSet); } ``` Edit: POC class https://gist.github.com/mburbea/c9a71ac1b1a25762c38c9fee7de0ddc2 More updates!

It includes all of the non-provider-specific types from System.Data.dll with the exception of permissions-related types (e.g. DbDataPermissionAttribute) and configuration-related types (e.g. DbProviderFactories). - I've done close to zero cleanup in the tests ported from Mono. There is a sizeable amount of work there to bring it into conformance with our normal usage of xunit, and I'll open an issue for that to be done subsequently. I did the minimal work necessary to bring the tests over, convert them to xunit, and get them passing. - I've done some cleanup/formatting/scrubbing/etc. in the product source, but there's still plenty more we could do if we want to, more application of C# features added since this code was written, etc. - I type-forwarded the SqlTypes down from System.Data.SqlClient into System.Data.Common, as they need to be known by DataSet and friends. SqlClient was accessing some internals of these types, so I put some workarounds in place to enable it to continue functioning without measurable performance loss and with the same behavior.

These are sequences that are generated on linux to represent certain keypresses, such as the arrow keys or the F1-F12 keys. They are also used for querying certain state about the terminal, such as the position of the cursor. In general, the parsing works well enough on Ubuntu, however, it is noticeably wrong on the Windows Subsystem for LInux. Try running powershell on WSL, and you'll see a number of graphical defects, primarily related to the retrieving of the cursor position (see [this code](https://github.com/dotnet/corefx/blob/master/src/System.Console/src/System/ConsolePal.Unix.cs#L360-L385)). Also attempting to use the arrow keys to scroll through the command history simply echos 'A', 'B', 'C', or 'D' to the input, depending on the arrow key. As we discussed, this is probably due to .NET Core missing certain characters while parsing the result, as opposed to blocking on the input and waiting, character by character, for the complete sequence to come in. 12455 area-Infrastructure Updating CoreFx dependencies to servicing-24607-01 /cc @dotnet/corefx-contrib 12457 area-System.Runtime Adding Delegate missing members Fixes #12251 Adding missing members for System.Delegate, System.MultiCastDelegate and MulticastNotSupportedException + tests. cc: @danmosemsft @stephentoub @AlexGhiondea @weshaggard 12458 area-System.IO Add missing IO members to System.Runtime - Adds ref entries for the 5 remaining IO members missing from System.Runtime - Adds tests for the FusionLog properties - Tests for the Stream functions are coming in a separate commit since those tests live in the System.IO assembly - Adds full test suite for FileNotfoundException since we apparently didn't have any progress towards https://github.com/dotnet/corefx/issues/9465 @joperezr @AlexGhiondea @stephentoub @JeremyKuhne 12459 area-System.Net Add missing members in System.Net.Sockets.SocketException ``` csharp public class SocketException : Win32Exception { protected SocketException(SerializationInfo serializationInfo, StreamingContext streamingContext); public override int ErrorCode { get; } } ``` (was tracked by #11788) 12460 area-System.Net Add back Socket.SendFile, Begin/EndSendFile ``` csharp public class Socket : IDisposable { public IAsyncResult BeginSendFile(string fileName, AsyncCallback callback, object state); public IAsyncResult BeginSendFile(string fileName, byte[] preBuffer, byte[] postBuffer, TransmitFileOptions flags, AsyncCallback callback, object state); public void EndSendFile(IAsyncResult asyncResult); public void SendFile(string fileName); public void SendFile(string fileName, byte[] preBuffer, byte[] postBuffer, TransmitFileOptions flags); } ``` (Was tracked by #11788) Additional missing APIs: ``` M:System.Net.Sockets.Socket.EndAccept(System.Byte[]@,System.IAsyncResult) M:System.Net.Sockets.Socket.EndAccept(System.Byte[]@,System.Int32@,System.IAsyncResult) P:System.Net.Sockets.SocketAsyncEventArgs.SendPacketsFlags M:System.Net.Sockets.SocketAsyncEventArgs.get_SendPacketsFlags M:System.Net.Sockets.SocketAsyncEventArgs.set_SendPacketsFlags(System.Net.Sockets.TransmitFileOptions) ``` 12461 area-Infrastructure Detect a better default for TestNugetRuntimeId when not set The logic [here](https://github.com/dotnet/corefx/blob/71de1aac5cf3e5dc87714ae0cc829e1fa98f7c5d/dir.props#L267) was reasonable when we only supported ubuntu.14.04-x64, but we support many more distros now.

The purpose of a RuntimeID is to describe the platform that an application is running on. For many target frameworks they've only been designed to accept a finite set of RIDs. I think the right model for this would be, given a TestTFM, select from the available RIDs which one best matches the current machine. /cc @weshaggard @karajas @mellinoe 12466 area-System.Threading Add netstandard1.7 build to Threading.Timers This retargets the ref and src to netstandard1.7.

On Unix, it ends up throwing a UriFormatException. A bunch of the Xml types end up hitting this code path when provided with a string uri, e.g. XmlReader.Create(string), which causes failures when file paths are provided on Unix, and creating readers and such for file paths is very common. This commit works around the issue by adding an explicit file scheme rather than leaving it up to the Uri implementation to determine that it's a file path. Note that there are tests which would have caught this, but they're not getting run: https://github.com/dotnet/corefx/issues/12483 Issue for Uris on Unix: https://github.com/dotnet/corefx/issues/1745 cc: @sepidehMS, @krwq, @davidsh, @cipop " 12492 area-System.Runtime Improvements in the System.Random methods "When relying on the `System.Random` methods, I usually expect to get unique numbers; or might prefer to only account for specific values within the input range (e.g., all the numbers from 0 to 1000 except 5, 10 and 200). That's why I am used to complement my calls to these methods with a code like this one: ``` C# private static int GetRandom(int min, int max, int[] toIgnore) { Random rand = new Random(); int outVal = min; while (true) { int number = rand.Next(min, max); if (!toIgnore.Contains(number)) { outVal = number; break; } } return outVal; } ``` This code can become a bit more complex under certain conditions to avoid too-slow/infinite loops, but it is a quite simple implementation anyway. Can I write a code like the aforementioned one every time I need `System.Random` to ignore certain numbers? Sure. Is such an eventuality part of the most common requirements associated with using random numbers (and, consequently, should these methods account for it)? I think so. I am also proposing to add new overloads for other commonly-used numeric types (i.e., `long` and `decimal`). Below these lines, you can find all the API calls associated with my proposal together with the existing ones. ``` C# public class Random { //---- Existing public int Next() { } public int Next(int maxValue) { } public int Next(int minValue, int maxValue) { } public double NextDouble() { } public void NextBytes(byte[] buffer) { } //---- New public int Next(int[] ignoredValues) { } public int Next(int maxValue, int[] ignoredValues) { } public int Next(int minValue, int maxValue, int[] ignoredValues) { } public long NextInt64() { } public long NextInt64(long[] ignoredValues) { } public long NextInt64(long maxValue) { } public long NextInt64(long maxValue, long[] ignoredValues) { } public long NextInt64(long minValue, long maxValue) { } public long NextInt64(long minValue, long maxValue, long[] ignoredValues) { } public double NextDouble(double[] ignoredValues) { } public decimal NextDecimal() { } public decimal NextDecimal(decimal[] ignoredValues) { } public void NextBytes(byte[] buffer, byte[] ignoredValues) { } } ``` In case of going ahead with these suggestions, I would like to take care of the implementation myself. Additionally and as discussed in some of my previous issues, I want to highlight my interest in minimising everyone's unnecessary efforts; for example, I wouldn't find any problem with a relatively quick ""sorry, but we aren't interested in this implementation for the time being"".

Can someone help? This is a static method in a static class. internal static IQueryable AsSQL( this IOrderedQueryable source, SqlQuerySpec querySpec) { if (querySpec == null) { throw new ArgumentNullException(""querySpec""); } if (string.IsNullOrEmpty(querySpec.QueryText)) { throw new ArgumentException(""querySpec.QueryText""); } return source.Provider.CreateQuery(Expression.Call(null, ((MethodInfo)MethodBase.GetCurrentMethod()).MakeGenericMethod( new Type[] { typeof(TSource), typeof(TResult) }), new Expression[] { source.Expression, Expression.Constant(querySpec) })); } " 12500 area-System.Linq Use flags pattern to control typecasting of Count() `IIListProvider` is supposed to represent an iterator that has optimized `ToArray()` / `ToList()` / `Count()` paths. However, not all implementations of `IIListProvider` can optimize for all 3 of those methods. For example: - [ConcatNEnumerableIterator.ToArray](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Concat.cs#L443) cannot be optimized since we need to determine the right amount to allocate in advance, but `ToList` can. - In my recent PR #12042 `Count` cannot be optimized for `Cast` since we might miss throwing an exception for an invalid cast, but `ToArray` / `ToList` can. - Another example is [SelectEnumerableIterator](https://github.com/dotnet/corefx/pull/11841/files#diff-0e401ce4761b21f560293373a0a40781R150) where we can't optimize for `ToArray` or `ToList` but can for `Count`. For providers where we can't optimize for a particular method, we just want to return `this.ToArray()` or `this.Count()`, etc. However, this leads to a stack overflow because `Enumerable.ToArray()` checks for `IIListProvider` again and calls `IIListProvider.ToArray()`. Our solution for this thus far has been to introduce separate methods, one that checks for IIListProvider and one that doesn't. For example, places where `ToArray` can't be optimized call `EnumerableHelpers.ToArray(this)`, and places where `ToList` can't be call `new List(this)`. Same for [Buffer](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Buffer.cs#L16). ## What this PR is My idea was that instead of having 2 versions of the same thing, one that does/doesn't check for a particular type, we could simply pass in flags to the method to tell it which types to cast to. The publicly exposed method (in this case `Count(IEnumerable)`) is just a wrapper around this method, telling it to try casting to all of the types. `IIListProviders` that cannot optimize their `Count` simply call ``` cs this.Count(Check.All & ~Check.IIListProvider); ``` to make `Count` not check for IIListProviders. Another neat side-effect of using this pattern is that we can fine-tune perf in cases where we call `Count()` but we know the enumerable is not of a certain type (pass in `Check.All & ~Check.ThatType`) or is one of two types (`Check.Type1 | Check.Type2`). This PR does that in a couple of files. cc @stephentoub, @VSadov, do you think this is a good change? 12501 area-Infrastructure Build error in SUSE 11 SP3 "When i try to build in `Linux sles11-sp3 3.0.101-0.15-default #1 SMP Wed Jan 22 15:49:03 UTC 2014 (5c01f4e) x86_64 x86_64 x86_64 GNU/Linux` corefx gives below error `corefx/src/Native/Unix/System.Native/pal_io.cpp:135:37: error: use of undeclared identifier 'IN_EXCL_UNLINK'; did you mean 'PAL_IN_EXCL_UNLINK'? static_assert(PAL_IN_EXCL_UNLINK == IN_EXCL_UNLINK, """"); ^~~~~~ PAL_IN_EXCL_UNLINK corefx/src/Native/Unix/System.Native/pal_io.h:281:5: note: 'PAL_IN_EXCL_UNLINK' declared here PAL_IN_EXCL_UNLINK = 0x04000000,` " 12503 area-Infrastructure Unhandled Exception: System.IO.IOException: Too many open files Opening an issue here as requested from https://github.com/xunit/xunit/issues/874.

beta-24607-00, respectively (master) /cc @dotnet/corefx-contrib 12505 area-Meta Merge Future branch into Master New APIs were added in the Future branch a while ago. It'd be nice if the changes were merged into Master so we could make the new APIs available in netcoreapp1.1. https://github.com/dotnet/corefx/compare/future Some examples: - #1384 - Regex group should have a Name property - #1783 - Add ConcurrentDictionary GetOrAdd/AddOrUpdate overloads with generic arg - #1756 - Implement generic interfaces on Regex collections - #2436 - Add async XLinq document/element loading and saving - #2862 - Add HashSet ctors with capacity 12506 area-System.Linq Reduce generic exception code bloat in System.Linq Currently System.Linq uses this pattern to handle invalid arguments: ``` cs if (source == null) { throw Error.ArgumentNull(nameof(source)); } ``` Where `ArgumentNull` gets inlined. This introduces significant jitted code bloat since the Linq methods are generic, so this code (which very rarely gets hit) is generated over and over again for different value types. We should convert all of this to the form ``` cs if (source == null) { Error.ThrowSourceArgumentNull(); // or ThrowArgumentNullSource } ``` As of dotnet/coreclr#6103 methods that are known to throw are not inlined, so this should help decrease code size. cc @benaadams 12507 area-System.IO Override BufferedStream.CopyToAsync to delegate to source stream PR https://github.com/dotnet/corefx/pull/12006 added an override of BufferedStream.CopyToAsync, but it doesn't compile because it pulls in a helper file that references types from System.Buffers.dll, which System.IO.dll doesn't currently reference. While that may change in the future, this PR fixes that by cherry-picking the initial commit and then adding a commit that splits the helper file into two, one that does the argument validation needed by this change and one that uses ArrayPool. I've also added a commit with additional tests for the CopyToAsync override. cc: @ianhays, @maddin2016 Fixes https://github.com/dotnet/corefx/issues/11572 12508 area-System.Net Add netstandard1.7 build to Net.Primitives Update System.Net.Primitives to netstandard1.7. Retarget the src and ref to netstandard1.7. Make the tests cross-compile for netstandard1.7/netstandard1.3. I preserved a UWP build of the library (now UAP10.1) because there was a significant amount of source here that we wouldn't want to get stale by not building it. /cc @stephentoub @weshaggard @danmosemsft @tijoytom @ericeil 12509 area-System.Runtime Proposal: Adding a concise API for throwing exceptions "## Background Argument validation is done a lot in .NET code. So much, in fact, that people almost always find that writing `throw new ArgumentNullException(...)` et al. each time is too verbose, and end up writing their own helper classes to throw exceptions. Some random examples I picked from GitHub: [Octokit.NET](https://github.com/octokit/octokit.net/blob/master/Octokit/Helpers/Ensure.cs#L16), [xUnit](https://github.com/xunit/xunit/blob/master/src/common/Guard.cs#L11), [System.Collections.Immutable](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/Validation/Requires.cs#L25). ## Proposal We should have an API in the BCL for this so people don't have to keep writing their own helper classes. Here's what an initial prototype could look like (similar to the S.C.I class I linked to above): ``` cs public static class Requires { public static void NotNull(T value, string paramName); // no T : class constraint to allow nullables // parameter names are same as ArgumentNullException, to allow easy conversion // for people using named parameters public static void NotNull(T value, string paramName, string message); public static void Range(bool condition, string paramName); public static void Range(bool condition, string paramName, string message); public static void Argument(bool condition, string message); // message comes first for ArgumentException public static void Argument(bool condition, string message, string paramName); } ``` How it would be used: ``` cs T Single(this IList list) { Requires.NotNull(list, nameof(list)); Requires.Argument(list.Count == 1, ""The input list needs to have only 1 item.""); return list[0]; } ``` ### Additional Notes In addition to providing a nice unified API, this may also lead to better performance / decreased memory consumption for .NET apps. Typically when people write their own helper APIs for this, they write it so that the `throw` is in the same clause as the check for the condition, i.e. ``` cs void NotNull(T value, string name) { if (value == null) { throw new ArgumentNullException(name); } } ``` or, alternatively, they have a method that returns an exception and throw that from the caller: ``` cs ArgumentNullException ArgumentNull(string name) { return new ArgumentNullException(name); } if (value == null) throw Error.ArgumentNull(nameof(value)); ``` Code snippet 1 is not likely to be inlined because of the `throw new ...`, while `ArgumentNull` in code snippet 2 does get inlined, resulting in generated code bloat for a `throw` path that will very rarely get called. If we wrote our own API for throwing exceptions, we could structure it so that the check gets inlined, but the throwing code doesn't: ``` cs void NotNull(T value, string name) { if (value == null) { ThrowArgumentNullException(name); } } void ThrowArgumentNullException(string name) => throw new ArgumentNullException(name); ``` Thoughts? cc @svick @benaadams @jkotas @GSPP @mellinoe @KrzysztofCwalina " 12510 area-System.Net Move HttpVersion to System.Net.Primitives HttpVersion is privately copied in `System.Net.Http` and `System.Net.Http.WinHttpHandler`. Moving it to lower-level contract will unify all these private copies. Note: Private copy in `Common` has two additional values in it. They are not in .NET 4.6 and Xamarin, so we can't add them in public netstandard2.0 contract.

I'm submitting this as its own PR, but added it as part of validating a bug fix I'm submitting separately. cc: @ianhays 12516 area-System.Console Fix Console.CursorLeft/Top handling in WSL Console.get_CursorLeft/Top work by issuing a request to the terminal by writing out a known sequence to stdout. The terminal then provides a response on stdin, again in a known format: \ESC[row;colR. Our current logic reads characters until it finds the escape, then reads until it finds the brace, and then reads until it gets a digit that starts the row. At that point, it parses whatever value it has in its input buffer and treats that as the row. Then it does the same for the column. This has worked fine on all of the systems we tested on, but it breaks in the Windows Subsystem for Linux. The reason is that the other systems all apparently write the response atomically, such that when we go to read the data, all of the digits for the row/column are available. But WSL writes each digit out individually, which means when we read the first digit, there's a good chance the remaining digits did not get read with it into our buffer, and we end up misinterpreting just that first digit as being the entire value. So for example, if WSL responds to a request with \ESC[12;34R, we're likely to interpret the current position as being 1,3 rather than 12,34. This commit fixes this by reading each character individually and not declaring that we're done parsing the row or column until we hit the known marker that comes after it, namely the ';' in the case of the row and the 'R' in the case of the col. (Note that I got rid of the extra buffering we were doing here, as it was flawed and would have added additional code to do it correctly with this new approach. If we determine that there's a noticeable performance impact to not having it, then we can add it in.) cc: @ianhays, @zadjii-msft, @lzybkr Contributes to https://github.com/dotnet/corefx/issues/12452 12517 area-System.Security System.Security.Cryptography.Native.OpenSsl not found on Ubuntu 14.04 "A SignalR sample project fails on Linux because it cannot find System.Security.Cryptography.Native.OpenSsl.

If I change the working directory with `cd /d C:\Windows` before exeucting the console application, it works. It also works if I open up a `cmd.exe` with administrative privileges. It also works if I run the console application directly from an elevated Visual Studio instance. But the combination of unelevated `cmd.exe` and a file share as a working directory, makes the application fail with the above exception.

Things to discuss for this addition: - Naming - Generic parameters, one or two? One, as this will only allow users to compute the offset between same types and, thus, limits the possibility of finding offsets that could cause alignment issues, see https://github.com/dotnet/corefx/issues/12593#issuecomment-253305078, e.g. for offset between `ref byte` and `ref double`. If an offset between two different types are needed this can be done by explicitly converting one of the `ref`s to the same type as the other e.g. ``` csharp ref byte b1 = ...; ref double d1 = ...; IntPtr byteOffset = ref Unsafe.ByteOffset(ref Unsafe.As(ref d1), ref b1); ``` - Return type, do we imagine we need several versions with different return types, that could influence naming? - Parameter naming and order? @jkotas @mellinoe @jamesqo @benaadams @omariom @davidfowl When we decide I could give a shot at adding this too to `Unsafe`. **Update 1**: Changed proposal to have only one generic argument. 12594 area-System.Net Port FtpWebRequest to core 12595 area-System.Net Add System.Net.IPAddress missing members Add back Address property Fixes #12131 12596 area-System.Text Implement generic interfaces on Regex collections for netcoreapp1.1 Port #1756 from Future to Master and expose the new APIs for netcoreapp1.1.

This change enables callers to request an import with the new EphemeralKeySet flag, which uses the PKCS12_NO_PERSIST_KEY flag to PFXImportCertStore. For callers who do not do any interop with Win32 directly everything should be invisible and work. Libraries which pass PCERT_CONTEXT values to Win32, or replicate the work of GetRSAPrivateKey, may not function as expected when passed an X509Certificate(2) object with an ephemeral key. This situation is already possible if someone were to have done a P/Invoke into PFXImportCertStore manually and constructed an X509Certificate(2) object over the pointer, the addition of this functionality just makes it easier to get into that state. Since ephemeral is not the default behavior the onus of compatibility rests with the code which specified the flag on the call to load the PFX. At this point the Windows implementation of EnvelopedCms is known to not work with ephemeral private keys, and that will be addressed in a later change. This feature has no impact on Linux builds, since the private keys there are always ephemeral. Before this change callers to X509Certificate2Collection.Import could specify unknown flags without an error, but due to Ephemeral and Persisted being incompatible flags the Import method has been aligned with the X509Certificate(2) constructors in terms of keyStorageFlag validation.

Unfortunately, it seems to be in a pretty bad state these days: the activity is terribly low for such an important stack, critical bugs are not fixed and [there's literally no plan for API convergence](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/issues/476). By opening a ticket here, I hope this ticket will draw more attention from MSFT. So here are my questions: - Is there any plan to realign IdentityModel for .NET Core with its .NET Desktop counterpart as part of API convergence/.NET Standard 2.0? The .NET Core version lacks many important APIs compared to the .NET Desktop bits (it's basically a simple port of the JWT handler plus a bunch of other types that were needed for things like the OpenID Connect middleware for ASP.NET Core to work correctly). - Can you share an approximative timeline for fixing the critical bugs? A few annoying bugs were reported in July/August and are still in need of an urgent fix (e.g [this bug](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/issues/477)). - Will IdentityModel for .NET Desktop get updates in the future? I'm mainly interested in knowing if it will ever support [`RSACng`](https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/issues/480#issue-169228203) and ECDSA. It's quite obvious that the Azure AD team doesn't currently have the human resources needed to manage such an important stack. Maybe it would be worth considering assigning new developers to IdentityModel or transferring its ownership to another team? It seems that the WCF team is currently relying on private IdentityModel bits to make WCF work, maybe they would be interested in collaborating to IM? /cc @vibronet @polita @brentschmaltz 12626 area-Infrastructure System.Collections references non-shipping targetGroup for System.Runtime "I noticed today that System.Collections references a ""netstandard1.7"" targetgroup config of System.Runtime. https://github.com/dotnet/corefx/blob/9eaf364b8ca8180bace20aab188b1efe6a55835f/src/System.Collections/src/System.Collections.csproj#L23 That's actually the default, and since S.R.builds doesn't contain a netstandard1.7 config we don't actually ship this dll.

If an asynchronous exception (eg. a ThreadAbortException) is thrown eg. on https://github.com/dotnet/corefx/blob/master/src/System.Threading/src/System/Threading/ReaderWriterLockSlim.cs#L300, the ExitMyLock() method will never be called and the next attempt to spin for the `_myLock` field (eg. if trying to exit the lock as part of a finally clause, or the next attempt to acquire the lock) will hang indefinitely. Perhaps it could also be meaningful to store the managed thread id instead of just 1 in the `_myLock` field while the lock is being held because it would have made this issue much easier to find. 12647 area-Serialization Remove dead code from System.Json And increase CC by hitting non C# (IL) branches /cc @stephentoub 12649 area-System.Reflection Cleanup misc System.Reflection tests Small stuff but another in my System.Reflection backlog /cc @stephentoub 12652 area-System.Diagnostics Add uap10.1 configuration to System.Diagnostics.Tracing Related with #12013 12655 area-System.Runtime Add tests for new String.Join overloads Once dotnet/coreclr/pull/7621 makes its way over to CoreFx, we need to add tests for the new APIs. 12657 area-System.Runtime Add more methods on System.Attribute.

Fixes #12131 12659 area-System.Net SocketAsyncEventArgs allocates unnecessary SafeHandles Every operation on a SocketAsyncEventArgs ends up allocating a SafeNativeOverlapped SafeHandle: https://github.com/dotnet/corefx/blob/2117bae3a6c9736033e6d1659821ff3a1069920b/src/System.Net.Sockets/src/System/Net/Sockets/SocketAsyncEventArgs.Windows.cs#L160 This is adding a significant amount of overhead to networking operations that are trying to be optimized via SocketAsyncEventArgs, e.g. in a benchmark that downloads from a localhost server 100MB via ReceiveAsync calls on a SocketAsyncEventArgs instance, we end up allocating almost 20K SafeNativeOverlapped instances for over 800KB of memory! These SafeHandles are just being stored into a field on the SocketAsyncEventArgs. Rather than allocating a SafeHandle for each, there are a variety of options, such as making the SocketAsyncEventArgs itself finalizable, or reusing the same SafeHandle and just replacing the pointer it guards. cc: @davidsh, @cipop, @ericeil 12660 area-System.IO Machine wide IsolatedStorage stores don't have same access rights on Unix Common app data has an underlying issue #12628.

The latter was done as it showed up as a significant source of allocations once the former was done. 1. Add NetworkStream.CopyToAsync override. This does several custom things. First, it uses ArrayPool for the buffer used in the copy operation. Second, it uses a SocketAsyncEventArgs to avoid per-operation costs related to the socket. And third, it then uses a custom awaitable to avoid async/Task-related overheads that would otherwise occur per-ReadAsync. 2. Removes a per-operation SafeHandle allocation from any operation on a SocketAsyncEventArgs. I wrote a little benchmark that connects a socket to a localhost server which serves up 10MB of data. It then creates a NetworkStream and does a CopyToAsync on it to copy all of the data to Stream.Null. And it does all of this 10 times. Prior to the changes, there are lots of allocations (I'm only showing line items with > 10K of impact): ![image](https://cloud.githubusercontent.com/assets/2642209/19401974/4f2f50e4-922c-11e6-87a8-443ce672736f.png) After adding CopyToAsync, most of the allocations go away, but we end up with a significant number of SafeNativeOverlapped SafeHandles: ![image](https://cloud.githubusercontent.com/assets/2642209/19401991/6bd3d68e-922c-11e6-90c8-2be3bc82844f.png) After the second fix to address the SafeHandles, our memory usage is much more reasonable: ![image](https://cloud.githubusercontent.com/assets/2642209/19402007/8f10b5cc-922c-11e6-89c3-56f951f835c6.png) (Most of what remains is unrelated to the actual operation being tested, and is coming from things elsewhere in the test app, e.g. strings created at startup.) cc: @ericeil, @davidsh, @cipop, @davidfowl, @benaadams Fixes #11573 Fixes #12659 12665 area-System.IO Make GetEnumerator a no-op Makes GetEnumerator() return an empty enumerator.

One of the configured repositories failed (CentOS-7 - Extras), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work ""fix"" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable extras 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower).

In these occasions, if I don't spot the test failure, the PR reviewer has to trigger the test run themselves, e.g. `Test Innerloop OSX Release Build and Test` This means that the reviewer then has to wait about an hour for the test run to finish, when they come back to the PR and then can merge. The apple/swift project has the `Test and merge` functionality built into their CI, which I propose adding to dotnetbot I.e. we add support for the following: ``` @dotnetbot Test and merge Innerloop OSX Release Build and Test ``` which does the following: - Runs the tests specified - If the test run passed, merge the PR - If the test run failed, don't merge the PR (optionally post an error message) This would reduce the churn of devs having to remember to trigger tests and then go back and merge once the tests have all passed! 12725 area-Meta Enhance APICompat to discover [Serializable] Presumably some of these are missing, since BinarySerialization had been removed. It's hard to say how many because it's not represented in the ref assemblies. This may not be much (or even any) since there are still 149 instances of it in the CoreCLR implementations and we inherit most of those implementations. We do need it back since it likely changes serialization behavior. To find them if any, we need to update the apicompat tool then run it against desktop impl on the LHS and CoreFX impl on the RHS. Any types that are present in CoreFX, but are missing the attribute, should have it added. @weshaggard sound about right? perhaps there's no much to do here, since it's all over CoreCLR. 12726 area-System.Security Move netstandard security attributes into System.Runtime.

Knuth's subtractive random number generator algorithm. This algorithm is somewhat obscure. I have found only [this paper](http://www.colostate.edu/~pburns/monte/rngreport.pdf) that can be said that refers to this algorithm. Therefore, I propose a change of the default RNG in `Random` class to the [Permuted Cogruential Generator(PCG)](http://www.pcg-random.org/). According to its site, PCG is: - [More difficult to predict](http://www.pcg-random.org/predictability.html#predictability-of-the-pcg-family) - Smaller both in code size (`InternalSample` will be only five lines of code and `Random`'s constructor will be another five lines) and in memory usage (just 16 bytes in comparison with the 232 bytes the existing RNG uses) - [More statistically random](http://www.pcg-random.org/statistical-tests.html#statistical-performance-of-the-pcg-family) It can also provide some [other useful features](http://www.pcg-random.org/useful-features.html). There is a more detailed comparison of PCG and other RNGs [here](http://www.pcg-random.org/other-rngs.html). I submitted https://github.com/dotnet/coreclr/pull/7477 to apply these changes, but I was told to temporarily close it and to open an issue instead for further discussion. The implementation is based on [this one](https://github.com/imneme/pcg-c-basic/blob/master/pcg_basic.c). It has also added some constructors to `Random` class that allow it to be seeded with the longer `ulong` seeds PCG allows. It also implements multiple codebooks. The original constructors are retained, so I guess this isn't a breaking API change. 12747 area-Microsoft.CSharp "Improve ""dynamic"" performance" @Opiumtm commented on [Fri Oct 14 2016](https://github.com/dotnet/coreclr/issues/7618) `dynamic` feature today have extremely awful performance. Dynamic typing in .NET languages (C#, VB) isn't used much, mostly because of intolerable slow performance and some bugs in implementation (there are memory leaks in dynamics, for example). Some third-party libraries provide fast reflection based on IL emit at runtime to have fast access to object members. Even standard reflection API provide means to create fast delegates to invoke at runtime: [MethodInfo.CreateDelegate](https://msdn.microsoft.com/en-us/library/hh194376%28v=vs.110%29.aspx) Performance measurement of `dynamic` reveal that it doesn't cache delegates and indeed is very unoptimized. [MethodInfo.CreateDelegate](https://msdn.microsoft.com/en-us/library/hh194376%28v=vs.110%29.aspx) provide performance almost as fast as direct call to a method (there is some performance penalty on delegate creation, but invocation of created delegate is almost free - so it can created on first invoke and then can be cached). `dynamic` is very much slower on subsequent method calls, although it can cache method invokes using `CreateDelegate`. Same performance improvements should be applied on other `dynamic` features. Dynamic method invocation is just an example of how it should be improved. --- @mikedn commented on [Fri Oct 14 2016](https://github.com/dotnet/coreclr/issues/7618#issuecomment-253782788) How exactly is this related to coreclr?

Steps to reproduce: - Create a console app (target any framework > 4.5.0, I don't know if lower versions have the problem) - Paste this code: ``` class Program { static void Main(string[] args) { System.Console.WriteLine(System.Environment.Version.ToString()); System.Console.WriteLine(""zh-Hant-CN""); System.Console.WriteLine(""Parent Name is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hant-CN"").Parent.Name); System.Console.WriteLine(""Parent LCID is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hant-CN"").Parent.EnglishName); System.Console.WriteLine(""Parent LCID is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hant-CN"").Parent.LCID); System.Console.WriteLine(""zh-Hans-CN""); System.Console.WriteLine(""Parent Name is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hans-CN"").Parent.Name); System.Console.WriteLine(""Parent Name is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hans-CN"").Parent.EnglishName); System.Console.WriteLine(""Parent LCID is: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hans-CN"").Parent.LCID); System.Console.WriteLine(""Same culture: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hant-CN"") .Equals(System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hans-CN"")).ToString() ); System.Console.ReadKey(); } } ``` - Run the compiled EXE (Any Cpu, Debug) on a Windows machine except Windows 10 (Windows Server 20012 R2 in my case) with the latest framework (4.6.2) and the latest updates installed. The output of the program will be (wrong?): ``` 4.0.30319.42000 zh-Hant-CN Parent Name is: zh-CHS Parent LCID is: Chinese (Simplified) Legacy Parent LCID is: 4 zh-Hans-CN Parent Name is: zh-CHS Parent Name is: Chinese (Simplified) Legacy Parent LCID is: 4 Same culture: True ``` On Windows 10 though the output is as expected: ``` 4.0.30319.42000 zh-Hant-CN Parent Name is: zh-CHT Parent LCID is: Chinese (Traditional) Legacy Parent LCID is: 31748 zh-Hans-CN Parent Name is: zh-CHS Parent Name is: Chinese (Simplified) Legacy Parent LCID is: 4 Same culture: False ``` Additionally, when creating the language ""zh-Hans-CN"" (Simplified) the Traditional Month Names (and other names) are used, so if you run this code you will get 'Same culture: true' in Windows < 10: ``` System.Console.WriteLine(""Same culture: "" + System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hant-CN"").Equals(System.Globalization.CultureInfo.CreateSpecificCulture(""zh-Hans-CN"")).ToString()); ``` I hope this is not the wrong repository because I have found here the source code of the class: https://github.com/dotnet/coreclr/blob/74967f89e0f43e156cf23cd88840e1f0fc94f997/src/mscorlib/src/System/Globalization/CultureInfo.cs#L584 Thank you.

Aes and TripleDES both did assignments via virtual property setters in their ctor, which were field assignments in .NET Framework. 3rd party implementations may have written properties which assumed that the ctor had run to completion, and they are broken by that behavioral change.

This commit adds AppContainer support to the Windows native build and also ports some custom CRT code to circumvent undefined API errors and make it WACK-friendly. - The result of this is that a clrcompression built with /p:TargetGroup=netcore50 will have the APPCONTAINER bit set. - When also building in Release, the imports of the clrcompression will be a limited set of the usual imports that allows use of the dll to pass the WACK supported API check. - The import methods of the Release netcore50 clrcompression are identical to the corresponding clrcompression shipped out of TFS, though the latter imports ""api-ms-win-core*"" whereas the former imports ""kernel32"" and ""ole32"". - This commit will need to be merged alongside a TFS commit to remove clrcompression entirely from the ""PackagesToPublish"" group. - Also modifies the external package imports of the AOT packages to use the last stable version which is how we do it for the release branch.

For example, the ones in which @stephentoub suggested overriding the async version, like #12037 and #11573, could be candidates, although I'm not familiar with their implementation details. `FileStream` seems it could certainly benefit from overriding, since you can [see a `Buffer.BlockCopy` call](https://github.com/dotnet/corefx/blob/master/src/System.IO.FileSystem/src/System/IO/FileStream.Win32.cs#L633) to the user-provided array.

Aes and TripleDES both did assignments via virtual property setters in their ctor, which were field assignments in .NET Framework. 3rd party implementations may have written properties which assumed that the ctor had run to completion, and they are broken by that behavioral change. This change makes the ctors look like they do in net462, aside from when net462 sets fields which don't exist. It also makes the tests fail if virtual setter dispatch was utilized (for any currently defined property, at least). cherry-pick of 53455257f1dd9a55623798f00b8dbeafbf5b7118 and 207e52e8b851c621e1a8f2cea5002f42192ea1b4 to the release/1.1.0 branch, with master-only TODO comments removed.

The design of the shared framework results in the dependency being considered to be satisfied even when a higher version was needed. So if someone has .NET Core 1.0 installed and pulls in a daily build of a cryptography library they might be missing native code changes that were assumed to be present as dependencies of the managed code. By changing to direct dependencies (changing the platform-specific package files to use IdPrefix instead of PackageTargetRuntime) the new .so files will be downloaded and deployed with the app (if they're a higher version that what is present in the shared framework). This is the master version for issue #12517. cc: @ericstj 12891 area-System.Reflection Finalize System.Reflection.Metadata public API surface for 1.1.0 release Since CoreFX 1.0.0 release we have added many new APIs to SRM to support Roslyn and other customers. We need to finalize these APIs for 1.1.0 as follows: - [x] Finish signature decoder - add generic context parameter and rationalize type provider interfaces - [x] Finish signing support in PEBuilder including PE checksum - [x] Finish new BlobReader public surface (IndexOf, Offset, SkipBytes, SeekOffset APIs) 12892 area-System.IO Add a more flexible special folder API The current `Environment.GetFolderPath()` is based on the pre Windows Vista `CSIDL` based `SHGetFolderPath`. This API was depreciated and doesn't have any of the special folders introduced in Vista and beyond. We've updated the internal implementation in CoreFX to use the new `SHGetKnownFolderPath`, which takes a Guid. If we exposed a Guid based API we would allow: 1. Accessing newer or user registered special folders in Windows without code updates 2. Creating entries that we map to some more abstract cross-plat concept 3. Allow adding mappings on different runtimes/platforms that don't require updating all of the others Something like the following: ``` C# public static class Environment { public static string GetFolderPath(Guid folderIdentifier) { } } public static class FolderGuids { // commonly used folder ids / concepts // potentially even have Windows/Unix specific class/subclass } ``` Adding values to the `SpecialFolder` enum can be complicated as there are assumptions baked into existing code that the values map directly to `CSIDL`'s. As such, the recommendation would be that the existing API be depreciated and the `Guid` API would be the primary. Behavior of asking for an unknown `Guid` would be the same as the existing API- we return `String.Empty`. I'll follow up shortly with a suggested set of predefined `Guid`s. 12893 area-System.Net System.Net.Security tests are broken when updating to the new coreclr When trying to update to the newest coreclr with PR #12836 some System.Net.Security tests started hanging. They all call the same API which launches a task that is awaited and apparently it never resolves. Tests that are in this state are: ``` SslStream_AuthenticateAsClientAsync_Supported_Success SslStream_AuthenticateAsClient_Supported_Success SslStream_AuthenticateAsClientAsync_AllSupported_Success SslStream_AuthenticateAsClientAsync_None_Success SslStream_AuthenticateAsClientAsync_Default_Success ``` I will disable those tests for now to unblock the coreclr update which some folks depend on, but this issue is to track why did those started failing. cc: @stephentoub @CIPop (people who have edited those tests) 12894 area-Meta Duplicate resource name warnings building on Unix "It looks like the Resgen/GenerateResource task on Unix flags these, but the one we get building on Windows does not (which would be nice to understand).

This means that people who want to find a value in an array with a custom comparer (e.g. a collection type that accepts an `IEqualityComparer`) typically resort to using for-loops or LINQ to find the value. These solutions are - slower than calling `Array.IndexOf` directly since it is specialized in such a way to avoid virtual method calls, so optimal implementations have to do something like [`ImmutableArray`](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableArray_1.cs#L360) where they check if the comparer is the default comparer and use `IndexOf` if that's the case, and otherwise fall back to a for-loop. - not as readable as just using `IndexOf`, but currently necessary since it doesn't accept a comparer. ## Proposal We should simply add overloads to `IndexOf` and `LastIndexOf` that accept comparers. ``` cs namespace System { public abstract class Array : ICloneable, IList, ICollection, IEnumerable, IStructuralComparable, IStructuralEquatable { public static int IndexOf(T[] array, T value, IEqualityComparer comparer); public static int IndexOf(T[] array, T value, int startIndex, IEqualityComparer comparer); public static int IndexOf(T[] array, T value, int startIndex, int count, IEqualityComparer comparer); public static int LastIndexOf(T[] array, T value, IEqualityComparer comparer); public static int LastIndexOf(T[] array, T value, int startIndex, IEqualityComparer comparer); public static int LastIndexOf(T[] array, T value, int startIndex, int count, IEqualityComparer comparer); } } ``` 12916 area-System.Net Port remaining methods in CookieCollection and CookieContainer Fixes https://github.com/dotnet/corefx/issues/12125 The required methods already exists , but were internal.

This was failing intermittently in tests because the NetworkAddressChanged and NetworkAvailabilityChanged tests were in different classes and thus could potentially run in parallel. If the NetworkAvailabilityChanged_JustRemove_Success test ran while one of the NetworkAddressChanged tests was in flight, it would fail with a null ref. I've fixed the product bug by adding a null check. I've also updated the tests so that all of these event handler tests are in the same class, and added explicit tests for this case that will deterministically fail if the product regresses.

"I've been trying to tighten a couple of WebSocket tests (specifically that [multiple outstanding `SendAsync` calls throws an exception](https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/tests/SendReceiveTest.cs#L85)), but ended up running into a problem: The internal, lower-level buffering means the data gets picked up, regardless of the delay in the server `Receive`ing the data. That is, in this: ```c# await cws.SendAsync( WebSocketData.GetBufferFromText("".delay5sec""), WebSocketMessageType.Text, true, CancellationToken.None); DateTime snd = DateTime.UtcNow; await cws.SendAsync( // second send WebSocketData.GetBufferFromText(""send buffer""), WebSocketMessageType.Text, true, CancellationToken.None); TimeSpan sndTime = DateTime.UtcNow - snd; DateTime rcv = DateTime.UtcNow; await cws.ReceiveAsync(WebSocketData.GetBufferFromText(""receive buffer""), CancellationToken.None); TimeSpan rcvTime = DateTime.UtcNow - rcv; ``` ... the second send completes almost instantaneously, while the receive delays 5 seconds. I need the opposite - that the _send_ delays 5 seconds, then the subsequent receive completes instantly. Note that my current assumption is that there's an underlying task on the server accepting reads even if the actual process is delayed for the 5 seconds, and thus I'm assuming we need a way to delay at a lower/outer level. If I'm wrong (like, if the data may also be buffered on the sender side, and thus not something the test may be able to handle), please educate me.

I wrote a simple benchmark that creates a producer and a consumer, where the producer WriteAsyncs 10K 1024 byte buffers to an SslStream, and a consumer reads with 1024 byte buffers until all data is consumed. To try to keep things isolated from the rest of the networking stack (as some common types are shared, making analysis more difficult), the SslStreams wrap NamedPipeServer/ClientStreams. Prior to this change, the allocations end up looking like this: ![image](https://cloud.githubusercontent.com/assets/2642209/19627173/0e937eb8-990f-11e6-8ee4-72fcc3988fed.png) This PR does two things: 1. It removes some of the Task-related costs by switching away from using Task.Factory.FromAsync in SslStream.WriteAsync/ReadAsync. When Stream didn't provide the Begin/EndRead/Write methods in the contract, SslStream's Begin/End methods were internal, and the implementation of Read/WriteAsync used FromAsync to delegate to them. But the base Stream's Read/WriteAsync overloads have an optimized implementation for delegating to the Begin/End methods, taking advantage of some Task internals. Now that Stream does expose Begin/EndRead/Write and SslStream overrides those, we can remove the FromAsync calls and just let the base stream do its thing. (In the future, we can improve on this further by avoiding going through Begin/End at all, but for now this simple change improves the allocation profile.) 2. On Windows, every call to EncryptMessage and DecryptMessage ends up going through a generic helper for dealing with SSPI. The interface to these methods uses only safe code, so arrays of classes end up getting passed, and ends up having to do lots of expensive things in order to deal with arbitrary inputs. But the encrypt/decrypt operations are relatively simple, and we can avoid all of those costs by just going to the SSPI calls directly. Previously, every encrypt/decrypt call would allocate 4 SecurityBuffer instances, a SecurityBuffer[4] array, a SecBuffer[4] array, a GCHandle[4] array, a byte[4][] array, and a SecBufferDesc... after this change, all of those except for the SecBufferDesc are gone. With these changes, a new profile of the same scenario looks like: ![image](https://cloud.githubusercontent.com/assets/2642209/19627225/0d05f6e2-9910-11e6-90e9-4e40a901f795.png) reducing allocation numbers/size by ~70%. Throughput also increased by ~15%. The remaining allocations after this change are: - The SecBufferDesc allocated in EncryptMessage/DecryptMessage. (We can get rid of that by changing the type to a struct and changing the interface to take a `SecBufferDesc*` (it can't be a `ref SecBufferDesc` as we need to be able to pass in `null`). That impacts a lot of code paths, though, so I haven't done it in this change.) - The Task returned from ReadAsync/WriteAsync. (The one from ReadAsync is mostly unavoidable, but if we rewrite the implementation with async/await, if the underlying write operation completes synchronously, we should be able to avoid the task returned from WriteAsync.) - A BufferAsyncResult, AsyncProtocolRequest, and boxed Int32 for each read operation. (By rewriting these methods with async/await, we should be able to eliminate the boxed Int32 entirely, and replace the other two with smaller allocations associated with the async state machine, removing them altogether if the operation completes synchronously.) - A LazyAsyncResult and an AsyncProtocol Request for each write operation. (Same possibilities as above.) We can then further reduce these for the CopyToAsync scenario by ammortizing most of the read-related costs. (The ReadWriteTask allocations showing up in all of the traces are from the named pipe streams and can be ignored for the purposes of this PR.)

These intermediate allocations/copying can be avoided by deleting the `ModuleInfo` concept and just using `ProcessModuleCollection` to build up the collection of `ProcessModule` objects directly. The implementation on Windows can be further improved by avoiding some more unnecessary allocations, such as using a single `char[]` instead of duplicate `StringBuilder` instances to retrieve each module's `ModuleName` and `FileName`, and changing `NtModuleInfo` to be a struct instead of a class. Profiling a simple app that just does `Process.GetCurrentProces().Modules` on Windows, yields the following results: Before: After: Further improvements could be made, such as potentially stackallocating some of the arrays on Windows, but this looked good enough for now. Also, a similar change could be made for `ThreadInfo`/`ProcessThread`, but I'll leave that to a subsequent PR. cc: @stephentoub " 12964 area-System.Security Add crypto provider wrappers "Port additional provider wrappers to System.Security.Cryptography.Algorithms and System.Security.Cryptography.Csp Address issues: https://github.com/dotnet/corefx/issues/9981 Add Crypto provider wrappers https://github.com/dotnet/corefx/issues/12323 Port additional System.Security.Cryptography.RandomNumberGenerator members Includes misc refactoring to RandomNumberGenerator files (to split into ""Implementation"" classes under the Interop folder).

I did a bunch of search-and-replace operations to fix them up and filled in the gaps by taking documentation from MSDN. Also changing the `cref` style to omit `T:`, `P:`, `M:`, `F:` prefixes, which enables the C# compiler to check the references properly; this uncovered a bunch of incorrect references to non-existing types or members. I'm not sure what the plan is with regards to XML documentation and building it to produce .NET Core documentation online.

See #12236. @davidsh @stephentoub 13007 area-System.Linq No write-back of mutable struct instances to live constant boxes "Consider the following test: ``` csharp [Theory] [ClassData(typeof(CompilationTypes))] public static void ValueTypeIndexAssign(bool useInterpreter) { Expression index = Expression.Property(Expression.Constant(new StructWithPropertiesAndFields()), typeof(StructWithPropertiesAndFields).GetProperty(""Item""), new Expression[] { Expression.Constant(1) }); Expression> func = Expression.Lambda>( Expression.Block( Expression.Assign(index, Expression.Constant(123)), Expression.Equal(index, Expression.Constant(123)) ) ); Assert.True(func.Compile(useInterpreter)()); } ``` which uses a lambda equivalent to: ``` csharp () => { o[1] = 123; return o[1] == 123; }; ``` where `o` is a mutable struct. With the expression interpreter, the assert succeeds, but with the expression compiler, the assert fails. The issue with the compiler is in the use of `unbox.any` upon accessing the `Closure.Constants` array slot containing the live constant containing the boxed instance of `new StructWithPropertiesAndFields()`. No write-back is ever attempted. Contrast this to: ``` csharp var o = new StructWithPropertiesAndFields(); Func f = () => { o[1] = 123; return o[1] == 123; }; Console.WriteLine(f()); ``` This will print true as well. The use of an `object[]` combined with `unbox.any` instructions for accessing live constants prevents the ability to perform a mutation on the original storage location. In fact, the emitted code is: ``` ldarg.0 ldfld class [System.Linq.Expressions]System.Runtime.CompilerServices.Closure::Constants ldc.i4.0 ldelem.ref unbox.any valuetype [Foo]StructWithPropertiesAndFields stloc.s V_4 ldloca.s V_4 ldloc.0 ldc.i4.s 123 call instance void valuetype [Foo]StructWithPropertiesAndFields::set_Item(int32,int32) ``` The use of `stloc` and `ldloca` originates from the `EmitAddress` case for the `Constant` node, so we create yet another copy prior to taking the address. With my pending changes on statically typed closures, this behavior will be corrected because the constants will be stored in a statically typed field in a closure class. Obtaining the address of the instance for use by the indexer assignment will emit `ldflda`. If we were to fix this in the current code, we'd have to check for (mutable non-primitive) structs and store them in a `StrongBox` in the `Constants` array slot instead, so we can avoid the use of `unbox.any` on the struct value (and the copying of the value to a temporary to obtain the address). Instead, we'd ""unbox"" the strong box from the `Constants` storage slot and `EmitAddress` for the `Value` field in the strong box.

The design of the shared framework results in the dependency being considered to be satisfied even when a higher version was needed. So if someone has .NET Core 1.0 installed and pulls in a daily build of a cryptography library they might be missing native code changes that were assumed to be present as dependencies of the managed code. By changing to direct dependencies (changing the platform-specific package files to use IdPrefix instead of PackageTargetRuntime) the new .so files will be downloaded and deployed with the app (if they're a higher version that what is present in the shared framework).

In `GetAllNetworkInterfaces`, we use reverse PInvokes, which under rare cases can throw exceptions. If the managed callbacks do not handle those exceptions, the process will crash, because application code cannot catch the exception. To fix this, I've aggregated all exceptions encountered during all callbacks, and thrown them after the completion of the shim call. I've also changed the `LinuxNetworkInterface` constructor code to ignore all exceptions encountered while reading and parsing network files. Any exception encountered in those blocks indicates that the data is either inaccessible or invalid. @stephentoub I'm still trying to run some manual tests against this code. 13068 area-Serialization Enable DCS/DCJS to Serialize ISerializable Types.

I refactored the core logic into a new struct called `LargeArrayBuilder` so now the method looks like ``` cs // Check for ICollection var builder = new LargeArrayBuilder(initialize: true); builder.AddRange(source); return builder.ToArray(); ``` As a result of this refactoring, we can use the buffering strategy employed by `ToArray` in other places where we were previously using `EnumerableHelpers.ToArray(this)` (such as `Select.ToArray` or `Concat.ToArray`) and simultaneously avoid some unnecessary indirection/field stores. This results in substantial speedup. Perf testing and analysis: [test code](https://github.com/jamesqo/Dotnet/blob/4f08d2a4ce3c2aedf9bafec1516ffe3d86c22e81/Program.cs), [data](https://gist.github.com/jamesqo/2c7c07ccf64a52f0d52c1bd8902e407d). The following patterns all see substantial speedups (where `e` is a lazy enumerable): - `e.Concat.ToArray` - `e.Append.ToArray` - `e.Append.Append.ToArray` - `e.Select.ToArray` - `e.OrderBy.Select.ToArray` (OrderBy returns an IPartition that sometimes can't get its count cheaply) Once this is merged I will change #12703 to make `Where` use it too, so all `Where.ToArray` calls should be substantially faster. cc @stephentoub @jkotas @VSadov @JonHanna 13077 area-System.Numerics CI failure in Matrix4x4Tests.Matrix4x4CreateFromYawPitchRollTest2 See https://ci.dot.net/job/dotnet_corefx/job/master/job/osx_release_prtest/2207. ``` 14:05:54 System.Numerics.Tests.Matrix4x4Tests.Matrix4x4CreateFromYawPitchRollTest2 [FAIL] 14:05:54 Yaw:575 Pitch:-125 Roll:-230 14:05:54 Expected: True 14:05:54 Actual: False 14:05:54 Stack Trace: 14:05:54 /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_release_prtest/src/System.Numerics.Vectors/tests/Matrix4x4Tests.cs(553,0): at System.Numerics.Tests.Matrix4x4Tests.Matrix4x4CreateFromYawPitchRollTest2() ``` 13078 area-System.Linq Fixing liftToNull behavior in AddChecked and adding tests This fixes issue #13048 where `AddChecked` was the only node type that didn't pass `liftToNull: true` to the `GetUserDefinedAssignOperatorOrThrow` method used to find a user-defined addition operator.

No semantic changes were made; this is mostly moving code around into separate files, addressing stylistic oddities, and adding documentation. ~~Once this is merged, the move of `ChildRewriter` to a separate file will cause a merge conflict / rebase requirement for https://github.com/dotnet/corefx/pull/12786.

For code coverage to work mscorlib.pdb and System.Private.Corelib.pdb need to be placed next to their implementations (in the directory of the test assembly). These symbols are not in the main nuget package. Possibilities - get the symbols package manually (eg https://dotnet.myget.org/F/dotnet-core/symbols/runtime.win7-x64.Microsoft.NETCore.Runtime.CoreCLR/1.2.0-beta-24619-02 ) and then crack it open - get from the symbol servers by using [symchk](https://msdn.microsoft.com/en-us/library/windows/hardware/ff560157%28v=vs.85%29.aspx) .. example, `symchk.exe /s https://dotnet.myget.org/F/dotnet-core/symbols \System.Private.CoreLib.ni.dll`.

" 13126 area-System.Linq Adding by-ref support in stack spilling in System.Linq.Expressions "This addresses issue #11740 on stack spilling limitations when dealing with `ref` parameters and value type instances. Dealing with this restriction manually can be quite bothersome; I've run into this personally when building a (de)serialization framework that emits expression trees for efficiency. However, when value types are involved and the generated expression uses `Try` nodes, it's easy to fall victim to this restriction. A trivial example of this limitation is shown below: ``` csharp var dt = Parameter(typeof(DateTimeOffset)); var e = Lambda>( Call( // a value type instance dt, typeof(DateTimeOffset).GetMethod(nameof(DateTimeOffset.AddYears)), // causes stack spilling TryFinally( Constant(1), Empty() ) ), dt ); // throws NotSupportedException var f = e.Compile(); ``` The code throws the following exception: ``` Unhandled Exception: System.NotSupportedException: TryExpression is not supported as a child expression when accessing a member on type 'System.DateTimeOffset' because it is a value type. Construct the tree so the TryExpression is not nested inside of this expression. at System.Linq.Expressions.Compiler.StackSpiller.RequireNotRefInstance(Expression instance) at System.Linq.Expressions.Compiler.StackSpiller.RewriteMethodCallExpression(Expression expr, Stack stack) at System.Linq.Expressions.Compiler.StackSpiller.RewriteExpression(Expression node, Stack stack) at System.Linq.Expressions.Compiler.StackSpiller.RewriteExpressionFreeTemps(Expression expression, Stack stack) at System.Linq.Expressions.Compiler.StackSpiller.Rewrite[T](Expression`1 lambda) at System.Linq.Expressions.Compiler.LambdaCompiler.Compile(LambdaExpression lambda, DebugInfoGenerator debugInfoGenerator) at System.Linq.Expressions.Expression`1.Compile() ``` Dealing with this in the suggested way requires an overhaul of the generated expression tree. Lifting this restriction seems worth the effort. The approach used in this PR is as follows: - Rather than throwing an exception from `RequireNotRefInstance` or `RequireNoRefArgs`, we use all these places to record the child expression's index of the value type instance or `ref` argument in the `ChildRewriter` instance. - When analysis of child expressions is done and the rewrite action is `SpillStack`, temporary variables for the spilled child expressions are created. The recorded `ref` information (by child expression index) is consulted to decide on whether to use a `ByRef` type instead. - In order to store a reference to a value to a `ByRef` temporary variable, a new internal-only `RefExpression` is used as the right-hand side of the assignment. This node behaves much like `ref` locals in C# 7.0. - The `LambdaCompiler` knows about the occurrence of `ref` locals and emits valid IL when encountering these. For example, rather than emitting `ldloca` to obtain a reference to a value-typed local, it can emit `ldloc` in case the local is a `ref` local introduced by spilling. Note that the use of an internal-only extension node is similar to the already existing internal-only `SpilledExpressionBlock` introduced by the stack spiller as well. These node types are only introduced during stack spilling and never leak to the user. For the example shown above, the rewritten expression tree after stack spilling looks like: ``` csharp var dt = Parameter(typeof(DateTimeOffset)); var t1 = Parameter(typeof(DateTimeOffset).MakeByRefType(), ""$temp$0""); var t2 = Parameter(typeof(int), ""$temp$1""); var e = Lambda>( Block( new[] { t1, t2 }, // save `ref dt` to a temporary variable Assign( t1, new RefExpression(dt) ), Assign( t2, TryFinally( Constant(1), Empty() ) ), Call( // emit for Call supports ref locals t1, typeof(DateTimeOffset).GetMethod(nameof(DateTimeOffset.AddYears)), t2 ) ), dt ) ) ``` Note that the construction of the rewritten expression tree during stack spilling does not use the `Expression` factory methods; instead, it uses `Make` methods and constructors on the node types. This enables nodes such as `Call`, `Member`, etc. to be constructed where the target instance or any arguments are `ByRef` types. The factory methods don't support these (and we don't want to change that now), but the changes to the `LambdaCompiler` emit functionality support the use of `ByRef` types in these positions (see `EmitInstance` and `AddressOf` changes). For the running example, the emitted IL code looks more or less like this: ``` .method valuetype System.DateTimeOffset lambda_method(valuetype System.DateTimeOffset) { .locals init ( [0] valuetype System.DateTimeOffset&, [1] int32, [2] int32 ) // spilling of instance (cf. EmitAddress) ldarga.0 stloc.0 // $temp$0 // evaluation stack empty, as required .try { ldc.i4.1 stloc.2 leave E } finally { endfinally } E: ldloc.2 stloc.1 // $temp$1 // perform the call in spilled operands ldloc.0 ldloc.1 call valuetype System.DateTimeOffset System.DateTimeOffset::AddYears(int32) ret } ``` This PR lifts the ""no ref"" restriction in pretty much all places, except for: - Arguments passed to `Method` of `BinaryExpression` and `UnaryExpression` (when can `ByRef` occur here?) - Arguments passed to the `Invoke` method of a dynamic call site (to be reviewed) - Instance of `MemberExpression` where `Member` is a property (what's there to spill in this case?) Many IL-level tests are included. Issue #13007 was uncovered by doing this work.

As discussed in this issue, lambda expressions with 0, 1, 2, or 3 parameters are very common. In addition, the properties `Name` and `TailCall` are having default values most of the time (for one, the factory calls emitted by the conversion of lambdas to expression trees omit these). Therefore there's quite some room to save on object sizes. For services like the one I'm working on in Bing, these size reductions add up quickly. The design is similar to `IArgumentProvider` used for expressions like `MethodCallExpression` etc. We introduce an `IParameterProvider` to represent a lambda expression's parameters. Unlike `IArgumentProvider`, this interface is internal-only for the time being; we can decide whether it'd make sense to expose it and implement it on `CatchBlock` and `BlockExpression` as well. All tricks played to avoid allocating a `ReadOnlyCollection` until the `Parameters` property is accessed is similar to what we do for `Arguments` on other nodes (e.g. `ReturnReadOnly` etc.). Access to `Parameters` is avoided in all relevant places, e.g. in visitors, the lambda compiler, etc. The only exceptions are the debug-view writer, debugger proxy types, and the `Update` method on `LambdaExpression` (analogous to nodes that have an `Arguments` property). The class hierarchy starts with a base type that only holds on to the `Body` expression. Subclasses for 0 through 3 parameters are provided next, using an `object` typed field to hold either the first parameter or the `ReadOnlyCollection`. This should all look familiar. Beyond three parameters, we use `ExpressionN` which holds on to the collection directly. For the cases where a non-null `Name` is present or a `true` value for `TailCall` is specified, a `FullExpression` is used. This has the same cost as the current `Expression`. In order to avoid changing `sealed override` properties to `abstract` or non-virtual properties to `virtual` on the existing types, I'm using `Core` properties marked as `abstract` which are used by the original (unchanged) properties. These include `Type`, `Name`, and `TailCall`. We can simplify this if changes to these modifiers are deemed non-breaking (note that `LambdaExpression` is `abstract` but has an `internal` constructor, so external users wouldn't be able to derive from this class anyway). CC @VSadov 13134 area-System.Net Overhaul System.Net library logging "There are a few problems with the existing solution: 1. In the original sources, logging was split across a GlobalLog class and a Logging class. Global-related tracing went to GlobalLog, and library-specific tracing went to Logging. When the sources were moved to corefx, this evolved into multiple EventSource-based types, most of which were in Common and were then src-included into each System.Net assembly. This has a significant problem, though, which is that the name/Guid identity of an EventSource can only exist once in a process, and subsequent EventSource instances with the same identity fail. This means that whichever assembly ends up logging something first wins, and all other tracing from other System.Net assemblies ends up being lost. 2. The split also may have made sense when all components shared the same GlobalLog, but now that GlobalLog is included as a unique EventSource instance in each assembly, it’s no longer global. This means that we’re not only loading multiple EventSources unnecessarily (each has its own costs), but we’re also duplicating logging, as some logging is done to one or the other, but some logging is done to both. 3. Due to sharing the Logging class, which evolved into an EventSource-based type, many logging calls had to include which component they came from as an enum value, leading to bloating at the call sites. 4. Additionally, many logging operations included the name of the method in which the calling was being done, which meant both longer call sites as well as stale values as members got renamed over time. 5. Call sites ended up getting fairly long due to lots of string concatenation operations and other manipulations in the logging call. This also then led to most call sites needing to be guarded behind checks for IsEnabled, leading to lots of code at every call site and obscuring the actual information being traced. 6. An additional requirement that got added with the move to corefx was that certain failure conditions should both Debug.Fail and do tracing, leading to some tracing operations taking upwards of 10 lines of code. All of these issues are addressed by this PR. - Each System.Net assembly that needs to log now loads a single NetEventSource type for doing logging, each with its own identity. - That implementation is split across a common, partial NetEventSource.Common.cs file used by all such assemblies, and then a per-assembly partial NetEventSource.AssemblyName.cs file used by the individual assembly. The former file contains most of the logging implementation. The latter files typically contain just the partial class declaration along with the [EventSource] attribute that gives that assembly’s NetEventSource its unique identity / name. - The logging operations in NetEventSource.Common.cs use a variety of relatively-recent language enhancements to improve the logging. Each operation uses a [CallerMemberName] so that the call sites don’t need to specify the caller. FormattableString is used so that call sites can use string interpolation while still providing the logging implementation the flexibility to format the individual components in a desired fashion (e.g. IntPtrs are formatted as hex, SafeHandles are rendered in a way that includes their name+hashcode+handle, etc.), along with a mechanism that allows individual libraries to add additional formatting rules. Each operation allows the this reference (or another this-like context object) to be passed in, to simply identify the source of the call (in concert with the caller member name). A debug-only mechanism is included in the tracing to help find potential perf issues due to misuse of the logger. Etc. - A Fail logging operation is included that both traces and does a Debug.Fail. With these changes, most call sites are greatly simplified. Some examples: Before: ``` C# if (GlobalLog.IsEnabled) { GlobalLog.AssertFormat(""ContextAwareResult#{0}::ContextCopy|Called on completed result."", LoggingHash.HashString(this)); } Debug.Fail(""ContextAwareResult#"" + LoggingHash.HashString(this) + ""::ContextCopy |Called on completed result.""); ``` After: ``` C# NetEventSource.Fail(this, ""Called on completed result.""); ``` Before: ``` C# if (NetEventSource.Log.IsEnabled()) NetEventSource.Enter(NetEventSource.ComponentType.Http, this, "".ctor"", handler); ``` After: ``` C# NetEventSource.Enter(this, handler); ``` Etc. In addition to fixing up all of the event sources, I of course also fixed up all usage in order to clean up the call sites. However, this was a rather mechanical change: I did not remove existing logging (other than duplication) nor did I add new logging. At some point, we should review the actual logging being done to determine what’s missing and what’s not needed. I also did not revise the additional existing events on the sockets and security event sources, but we may want to remove those (or some of those) in favor of just using the shared events.

When not running under sudo, `Get-Process -Id ` fails to get the process. This only happens if the target process is not owned by the current user. After some digging, it seems like it's related to how `ProcessManager.Unix.cs` tries to figure out if the given process is running or not. It does so by trying to issue a `Kill` command against the process: [System/Diagnostics/ProcessManager.Unix.cs](https://github.com/dotnet/corefx/blob/421407e7831356f7f28f48b35da9e58b43e0d6f2/src/System.Diagnostics.Process/src/System/Diagnostics/ProcessManager.Unix.cs#L26-L31) ``` public static bool IsProcessRunning(int processId) { // kill with signal==0 means to not actually send a signal. // If we get back 0, the process is still alive. return 0 == Interop.Sys.Kill(processId, Interop.Sys.Signals.None); } ``` As opposed to `ProcessManager.Windows.cs`, which looks up the given processId in an array of processIds for currently running processes. I think it's running into permission issues because non-privileged users cannot signal processes not owned by themselves. `man 2 kill` actually describes the required permissions [kill(2)](https://linux.die.net/man/2/kill) / [Kill Permissions](https://www.gnu.org/software/libc/manual/html_node/Permission-for-kill.html#Permission-for-kill) ``` If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a process ID or process group ID. For a process to have permission to send a signal it must either be privileged (under Linux: have the CAP_KILL capability), or the real or effective user ID of the sending process must equal the real or saved set-user-ID of the target process. In the case of SIGCONT it suffices when the sending and receiving processes belong to the same session. (Historically, the rules were different; see NOTES.) .... Linux notes Across different kernel versions, Linux has enforced different rules for the permissions required for an unprivileged process to send a signal to another process. In kernels 1.0 to 1.2.2, a signal could be sent if the effective user ID of the sender matched effective user ID of the target, or the real user ID of the sender matched the real user ID of the target. From kernel 1.2.3 until 1.3.77, a signal could be sent if the effec‐ tive user ID of the sender matched either the real or effective user ID of the target. The current rules, which conform to POSIX.1-2001, were adopted in kernel 1.3.78. ``` ## Repro ### Environment ``` nasir:~/proctest$ ~/.dotnet/dotnet --info .NET Command Line Tools (1.0.0-preview3-003842) Product Information: Version: 1.0.0-preview3-003842 Commit SHA-1 hash: 3ae14ab618 Runtime Environment: OS Name: ubuntu OS Version: 14.04 OS Platform: Linux RID: ubuntu.14.04-x64 ``` Also tested on Ubuntu 16.04, with `dotnet-dev-1.0.0-preview2-003131` ### Current Process list ``` nasir:~/proctest$ ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 0 2432 ? 00:00:00 /init nasir 2 1 0 2432 ? 00:00:02 /bin/bash root 2209 2 0 2432 ? 00:00:00 sudo bash root 2210 2209 0 2432 ? 00:00:00 bash nasir 2480 2 0 2432 ? 00:00:00 ps -ef ``` ### Testcode ``` using System; using System.Diagnostics; class Program { static void Main(string[] args) { if(args.Length != 1) { Console.WriteLine(""no input""); return; } try { int pid = Int32.Parse(args[0]); Process p = Process.GetProcessById(pid); Console.WriteLine(""PID: {0} Name: {1}"", p.Id, p.ProcessName); } catch(Exception ex) { Console.WriteLine(ex); } } } ``` ### Results Running against own process, expected results. ``` nasir:~/proctest$ ~/.dotnet/dotnet run 2 Project proctest (.NETCoreApp,Version=v1.0) was previously compiled.

I tracked down to user getting duplicate ""home"" environment variables just the casing was different from `System.Environment.GetEnvironmentVariables()`. I just did quickfix to ignore if duplicates had same value and warn if value differed, now Cake started fine. Today when the original issuer tested the fix Cake indeed started fine but no tools would start. We set a couple of Cake specific environment variables and in that process we got this error: ``` Error: System.ArgumentException: Item has already been added. Key in dictionary: 'home' Key being added: 'HOME' at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Diagnostics.ProcessStartInfo.get_EnvironmentVariables() at Cake.Core.Polyfill.ProcessHelper.SetEnvironmentVariable(ProcessStartInfo info, String key, String value) at Cake.Core.IO.ProcessRunner.Start(FilePath filePath, ProcessSettings settings) at Cake.Core.Tooling.Tool1.RunProcess(TSettings settings, ProcessArgumentBuilder arguments, ProcessSettings processSettings) at Cake.Core.Tooling.Tool1.Run(TSettings settings, ProcessArgumentBuilder arguments, ProcessSettings processSettings, Action1 postAction) at Cake.Core.Tooling.Tool1.Run(TSettings settings, ProcessArgumentBuilder arguments) at Cake.Common.Tools.NuGet.Restore.NuGetRestorer.Restore(FilePath targetFilePath, NuGetRestoreSettings settings) at Cake.Common.Tools.NuGet.NuGetAliases.NuGetRestore(ICakeContext context, FilePath targetFilePath, NuGetRestoreSettings settings) at Cake.Common.Tools.NuGet.NuGetAliases.NuGetRestore(ICakeContext context, FilePath targetFilePath) ``` With help of strack trace I tracked down the issue to [ProcessStartInfo.EnvironmentVariables](https://referencesource.microsoft.com/#System/services/monitoring/system/diagnosticts/ProcessStartInfo.cs,5611ad13d0b7376e,references) and [ProcessStartInfo.Environment](https://github.com/dotnet/corefx/blob/bffef76f6af208e2042a2f27bc081ee908bb390b/src/System.Diagnostics.Process/src/System/Diagnostics/ProcessStartInfo.cs#L82) Our code to set the Cake specific variables basically looked like below ``` csharp #if NETCORE info.Environment[key] = value; #else info.EnvironmentVariables[key] = value; #endif ``` So in a naive initial attempt to work around I tried to lookup key and set it with that key so it was the same casing, that worked fine on posix, but not on Windows. Strangely `ProcessStartInfo` didn't blow up if I didn't set any envvars, so I started thru reference source and corefx and found similar code we had in Cake before I added value comparison and warnings. [Reference source](https://referencesource.microsoft.com/#System/services/monitoring/system/diagnosticts/ProcessStartInfo.cs,193) looked like this: ``` csharp #if PLATFORM_UNIX environmentVariables = new CaseSensitiveStringDictionary(); #else environmentVariables = new StringDictionaryWithComparer (); #endif // PLATFORM_UNIX foreach (DictionaryEntry entry in System.Environment.GetEnvironmentVariables()) environmentVariables.Add((string)entry.Key, (string)entry.Value); ``` And [corefx](https://github.com/dotnet/corefx/blob/bffef76f6af208e2042a2f27bc081ee908bb390b/src/System.Diagnostics.Process/src/System/Diagnostics/ProcessStartInfo.cs#L103) looked like this: ``` csharp if (_environmentVariables == null) { IDictionary envVars = System.Environment.GetEnvironmentVariables(); _environmentVariables = new Dictionary(envVars.Count, CaseSensitiveEnvironmentVariables ? StringComparer.Ordinal : StringComparer.OrdinalIgnoreCase); IDictionaryEnumerator e = envVars.GetEnumerator(); try { while (e.MoveNext()) { DictionaryEntry entry = e.Entry; _environmentVariables.Add((string)entry.Key, (string)entry.Value); } } finally { (e as IDisposable)?.Dispose(); } } ``` That explained why I only encountered the error when using the property as it was lazy loaded. The original issue it was a GIT commit hook the resulted in the ""double"" home/HOME variables, but when digging deeper I found some non .NET based build agents happily all possible variants of ""home"". So I dug deeper to see if I could repro in .NET and initial answer was no (due too StringDictionary lower casing and OrdinalIgnoreCase comparer on the dictionary). Thru reflection though I was able to initialize the `ProcessStartInfo` `environmentVariables` field before property was used with a case sensitive implementation similar to the posix one. Then I could add variables like this ``` csharp startInfo.EnvironmentVariables[""a""] = ""B""; startInfo.EnvironmentVariables[""A""] = ""b""; ``` The child process could easily iterate environment variables like this ``` csharp foreach (DictionaryEntry entry in Environment.GetEnvironmentVariables()) { Console.WriteLine(""Key: {0}, Value: {1}"", entry.Key, entry.Value); } ``` and it outputted: ``` Key: A, Value: b Key: a, Value: B ``` but if I tried to start a child process with specified custom envars like this ``` csharp var startInfo = new ProcessStartInfo(assemblyLocation, ""3"") {UseShellExecute = false}; startInfo.EnvironmentVariables[""C""] = ""d""; new Process { StartInfo = startInfo }.Start(); } ``` it would blow up (obviously because duplicate key) ``` System.ArgumentException: Item has already been added. Key in dictionary: 'A' Key being added: 'a'... ``` Not setting custom environment variable worked fine though: ``` csharp new Process { StartInfo = new ProcessStartInfo(assemblyLocation, ""4"") {UseShellExecute = false} }.Start(); ``` So what am I missing? Is there some reason behind this behavior? It feels a bit fragile that adding one envvar to parent process can mess up the runtime for all child processes, not good at all.

See comment at https://github.com/dotnet/corefx/pull/13158#discussion_r87054718 A couple of changes: - The `InsertRange` overload accepting an `ImmutableArray` is specialized to just use `Array.Copy` instead of deferring to the `IEnumerable` overload. - The `AddRange` that accepts an `ImmutableArray` now defers to this instead of the `AddRange` that takes an enumerable. - `ImmutableArray.CreateRange` optimization where we return an empty array for 0-length sequences has been moved downstream to `ImmutableExtensions.ToArray`. - For use by `AddRange`, introduce an `ImmutableExtensions.CopyTo` method which copies directly to the underlying array if possible. - We only do this for well-known types since a bad ICollection implementation might hold on to the array; if the addend is not an array, List, or ImmutableArray, then we fallback to using foreach. - This optimization also benefits lazy enumerables since they are captured into a list during `ImmutableExtensions.GetCount`. - It penalizes slightly types that implement ICollection/IReadOnlyCollection but not IList, like Queue (1 extra typecast), and significantly for types that implement IList but aren't well known, like LinkedList (4 extra typecasts). - Add testing and convert related tests to use `Theory` for brevity cc @stephentoub, @AArnott 13159 area-Infrastructure How to locally compile corefx on Windows?

"As I chronicle at one point in #12487 , `ReceiveAsync` has very different failure behaviors between Windows and all other platforms (potentially to other Windows platforms, too). Note this behavior is **not** the result of a race condition. I expect that `SendAsync` is also affected by this, but haven't investigated fully. The critical part for Windows is in [WinHttpWebSocket](https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/src/System/Net/WebSockets/WinHttpWebSocket.cs#L395-L446), but what ends up happening is that when the second call to `ReceiveAsync` happens, the second call sets up the exception on the TCS returned by the _first_ call, then also returns that **same** task: ```c# if (receiveOperationAlreadyPending) { var exception = new InvalidOperationException( SR.Format(SR.net_Websockets_AlreadyOneOutstandingOperation, ""ReceiveAsync"")); _operation.TcsReceive.TrySetException(exception); Abort(); } return _operation.TcsReceive.Task; ``` (Given the locking that occurs, this is guaranteed to happen even if submitted on two concurrently running threads, although which one gets it would be up in the air) This is clearly different from the behavior on Linux/elsewhere, when going through [ManagedWebSocket](https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/src/System/Net/WebSockets/ManagedWebSocket.cs#L288-L309) it returns a separate task containing an `InvalidOperationException`, leaving the first task to complete ""on it's own"" - it dies as `Abort`ed, I believe throwing a `WebSocketException`: ```c# try { WebSocketValidate.ThrowIfInvalidState(_state, _disposed, s_validReceiveStates); Debug.Assert(!Monitor.IsEntered(StateUpdateLock), $""{nameof(StateUpdateLock)} must never be held when acquiring {nameof(ReceiveAsyncLock)}""); lock (ReceiveAsyncLock) // synchronize with receives in CloseAsync { ThrowIfOperationInProgress(_lastReceiveAsync); Task t = ReceiveAsyncPrivate(buffer, cancellationToken); _lastReceiveAsync = t; return t; } } catch (Exception exc) { return Task.FromException(exc); } ``` .... sooooo, what's the expected behavior here?

Now, and some interesting hard coded dates that exercise things in the middle. That should be the data set we feed into all the parsing code.

My scenario: I'm creating an integration for [opentracing.io](https://opentracing.io) - a *distributed tracing standard*. I'm creating ""spans"" (objects with tracing information) for several interesting components (HTTP calls, SQL calls, etc.). Spans are created in a hierarchy: e.g. ASP.NET Core request starts root span, outgoing HTTP call creates child span, ... I'm storing spans in a stack in AsyncLocal storage - So as long as there is a parent component that started a root span and can catch exceptions (e.g. ASP.NET Core request), I'm able to finish all open spans. However, an outgoing HTTP call could also be a root span if there is no parent component - e.g. in a background call, etc. If there's an exception in that case, I'm ""out of scope"" and haven't found a way to access my object. /alphabetical cc for participants from #5881: @avanderhoorn @davidsh @delmyers @nbilling @stephentoub @vancem" 13173 area-System.Net "Dns.GetHostAddressesAsync() Error: ""Device Not Configured""" Hii, I'm currently developing an ASP .NET Core Application on my mac using VS Code.

Fixes #12780 /cc @karajas" 13184 area-System.IO Optimize DeflateStream.CopyToAsync "Today, CopyToAsync on DeflateStream is the basic read/write loop. However, all CopyToAsync really needs to do on DeflateStream is transform the source data (via a synchronous operation) and pass it along to the destination. This means that we can improve its implementation by effectively having the source stream CopyToAsync to the destination stream, albeit with that transformation added in the middle. Doing this has a three key benefits: - It eliminates the read operations and the associated copy, allowing the source to effectively push directly to the inflater inside DeflateStream. - It takes advantage of any optimizations the source stream has in its CopyToAsync implementation, e.g. MemoryStream simply passing its whole internal buffer, NetworkStream using a SocketAsyncEventArgs (https://github.com/dotnet/corefx/pull/12664), FileStream reusing its async state (https://github.com/dotnet/corefx/pull/11569), etc. - CopyToAsync is typically used when no other reading has been done from the stream. Since this change causes CopyToAsync to bypass the internal buffer used by DeflateStream before the inflater itself, we can avoid allocating that buffer at all if CopyToAsync is used by itself. This avoids an 8K allocation per DeflateStream instance, and even if we switch to pulling this buffer from ArrayPool, it still avoids needing to rent/return with the ArrayPool in these cases. (I also noticed an unnecessary allocation in Inflater, which I removed.) The net effect of this change is a sizeable boost on throughput for many scenarios (I didn't find any scenarios where it regressed). Here are a few examples. In this table, ""MS"" is a memory stream, so ""MS to MS"" is using DeflateStream created around a compressed MemoryStream and using CopyToAsync on the DeflateStream to decompress it to another MemoryStream. ""CMS"" is a ""CustomMemoryStream"", which is simply a type that derives from MemoryStream and doesn't add or override any logic; this derivation defeats some the CopyToAsync optimization in MemoryStream, so this is essentially the worst case for this DeflateStream optimization. And ""FS"" is FileStream, where a ""(true)"" suffix means useAsync==true (in which case FileStream has its own CopyToAsync implementation) and a ""(false)"" suffix means useAsync==false (in which case it essentially delegates back to the base Stream's CopyToAsync). ""Len"" is the length of the original random input in bytes, and ""Iters"" is the number of iterations (the number of times positions were reset and CopyToAsync was called). | Test | Before (s) | After (s)| |---------------------------------------------------|-----------|-----------| | MS to MS (Len=1024 Iters=1024000) | 2.767149 | 1.601566 | | MS to MS (Len=1048576 Iters=1000) | 0.419615 | 0.139993 | | MS to MS (Len=10485760 Iters=100) | 0.358287 | 0.223764 | | CMS to CMS (Len=1024 Iters=1024000) | 2.832110 | 1.963891 | | CMS to CMS (Len=1048576 Iters=1000) | 0.271432 | 0.202536 | | CMS to CMS (Len=10485760 Iters=100) | 0.347356 | 0.316338 | | FS(True) to FS(True) (Len=1024 Iters=102400) | 10.315941 | 6.909713 | | FS(True) to FS(True) (Len=1048576 Iters=100) | 0.940410 | 0.124353 | | FS(True) to FS(True) (Len=10485760 Iters=10) | 1.000786 | 0.152991 | | FS(True) to FS(False) (Len=1024 Iters=102400) | 9.936322 | 6.967522 | | FS(True) to FS(False) (Len=1048576 Iters=100) | 0.705946 | 0.085895 | | FS(True) to FS(False) (Len=10485760 Iters=10) | 0.925196 | 0.159865 | | FS(False) toFS (True) (Len=1024 Iters=102400) | 8.630263 | 6.699364 | | FS(False) toFS (True) (Len=1048576 Iters=100) | 0.880577 | 0.116051 | | FS(False) toFS (True) (Len=10485760 Iters=10) | 0.862978 | 0.142838 | | FS(False) toFS (False) (Len=1024 Iters=102400)| 5.260478 | 4.388572 | | FS(False) toFS (False) (Len=1048576 Iters=100) | 0.346608 | 0.078440 | | FS(False) toFS (False) (Len=10485760 Iters=10) | 0.432393 | 0.157312 | Fixes https://github.com/dotnet/corefx/issues/11571 Contributes to https://github.com/dotnet/corefx/issues/12549 cc: @ianhays, @JeremyKuhne, @geoffkizer, @benaadams, @davidfowl (@ianhays, please pay careful attention to my use of the inflater.

For example, when TypeDescriptor.GetProperties is called, it ends up returning a weakly cached PropertyDescriptorCollection, so multiple threads accessing this could get the same collection. Then when using the reflection-based provider, the ReflectPropertyDescriptor instances this contains may be accessed concurrently by multiple threads. That then means that a pattern like this: https://source.dot.net/#System.ComponentModel.TypeConverter/System/ComponentModel/ReflectPropertyDescriptor.cs,289 is not safe: ```C# private object DefaultValue { get { if (!_state[s_bitDefaultValueQueried]) { _state[s_bitDefaultValueQueried] = true; Attribute a = Attributes[typeof(DefaultValueAttribute)]; if (a != null) { _defaultValue = ((DefaultValueAttribute)a).Value; // Default values for enums are often stored as their underlying integer type: if (_defaultValue != null && PropertyType.GetTypeInfo().IsEnum && PropertyType.GetTypeInfo().GetEnumUnderlyingType() == _defaultValue.GetType()) { _defaultValue = Enum.ToObject(PropertyType, _defaultValue); } } else { _defaultValue = s_noValue; } } return _defaultValue; } } ``` This would be fine if it were accessed serially, but if it's accessed concurrently, a thread could check ```_state[s_bitDefaultValueQueried]``` find that it hasn't been set yet, and then proceed to set it before actually setting ```_defaultValue```. Another thread could come along between the setting of ```_state[s_bitDefaultValueQueried]``` and the setting of ```defaultValue``` (which can actually be a relatively wide window, given the use of reflection in between), see that ```_state[s_bitDefaultValueQueried]``` has been set, and proceed to use the value of ```_defaultValue``` This is the cause of https://github.com/dotnet/corefx/issues/12753. 13216 area-System.Runtime Add Copy from ref T1 to ref T2 on System.Runtime.CompilerServices.Unsafe (Api) Hi, I would like to introduce a new public method for `System.Runtime.CompilerServices.Unsafe` Basically a method that allows to do something like: ```csharp public static void Write(ref TDest dest, ref TSrc src) { dest = src; } ``` that would translate to: ```csharp .method public hidebysig static void Write (!!TDest& dest, !!TSrc& src) cil managed { .maxstack 2 IL_0000: ldarg.0 IL_0001: ldarg.1 IL_0002: cpobj !!TSrc IL_0007: ret } ``` The usage scenario is to be able to efficiently copy a blittable data of type `TSrc` to a destination of type `TDest`, where we know that `TDest` has enough space to store `TSrc`. This method generates optimal code for such a case and is particularly useful for writing efficient value copy/writer. If this is ok, I can make a PR.

This does not attempt to fix all of them, just address the symptoms of the ones that have been causing some failed tests. In particular, the static TypeDescriptor.GetProperties will return a cached collection of instances, which means that instances end up being shared between threads. Each ReflectPropertyDescriptor instance has properties that check whether a bit flag contains a bit indicating that the value has been lazily created, and if it doesn't, sets the bit, then creates and stores the value. This leads to a variety of race conditions, including two threads racing to access the same value and one of them getting back the uninitialized value (this can also happen if an exception occurs in one thread before updating the value, leaving the flag set but the value uninitialized), and including two threads racing to access different fields but cloberring each other's updates to the state flags. This PR addresses those two issues specifically (there are very likely others), by a) setting the bit only after the fields have been set, and b) using compare/exchange operations to update the set bits. The desktop code has the same issues, and I'm just making enough changes to avoid the test failures we've been seeing that arise due to this. cc: @AlexGhiondea, @chlowell, @twsouthwick, @safern Fixes https://github.com/dotnet/corefx/issues/12753 Fixes https://github.com/dotnet/corefx/issues/13215 13225 area-System.Net Disable tests for clean CI ServerAsyncAuthenticate_AllClientVsIndividualServerSupportedProtocols_Success HttpClient_ClientUsesAuxRecord_Ok Ref: #8744, #11623 13229 area-System.IO Update to CoreCLR FileStream Take the latest CoreCLR and use its copy of FileStream. @ianhays @stephentoub @weshaggard @alexghi 13231 area-System.Diagnostics Update S.Diagnostics.Debug to ns2.0 Fixes #12794 /cc: @AlexGhiondea @joperezr 13233 area-Infrastructure Add full support build for test runs on Fedora 24 Now that we've updated buildtools, we can enable full test runs on Fedora 24.

After spending many hours tracking down [this bug](https://github.com/simpleinjector/SimpleInjector/issues/323) in Simple Injector, I came to the conclusion that: - `System.Type` instances are guaranteed to be unique within a single AppDomain. - `System.MemberBase` instances are guaranteed to be unique within a single AppDomain. - `System.ParameterInfo` instances are ***not*** guaranteed to be unique. When looking at the source code for `System.Type`, `System.Type.GetMembers()` and related methods it becomes clear that for each type there will be at most one `System.Type` instance and for each type member, there will be at most one `MemberBase` instance. For some weird reason however, this doesn't hold for `ParameterInfo` instances. When looking at `ConstructorInfo.GetParameters()` we can see that the creation of `ParameterInfo` objects is not protected by a lock and multiple concurrent threads can cause multiple `ParameterInfo` instances to be published for the same 'physical' parameter. I think this is a bug, or at least this is a design quirk, because developers will typically assume all reflection types to be unique within a single app domain. 13266 area-System.Runtime Break S.Security.Permissions dependency in S.R.Extension library S.Runtime.Extensions cannot depend on System.Security.Permissions so this change breaks that dependency. cc @rahku @kouvel @stephentoub 13267 area-System.Data ON AZURE: System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SNILoadHandle' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'sni.dll': "After publishing my .net core mvc app to AZURE I get the following exception whenever an attempt is made to create an instance (doesn't matter if direct or via DI) of my data context: ``` Application startup exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.TdsParser' threw an exception. ---> System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SNILoadHandle' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'sni.dll': The specified module could not be found.

I think the bug is FileStream.cs around [here](https://github.com/dotnet/corefx/blob/master/src/System.IO.FileSystem/src/System/IO/FileStream.Win32.cs#L919). `numBytes` gets set to a non-sector-aligned value and reused for the `ReadFileNative` which [is illegal with FILE_FLAG_NO_BUFFERING](https://msdn.microsoft.com/en-us/library/windows/desktop/cc644950(v=vs.85).aspx). I'm testing with .NET 4.6.2, so the source looks a bit different, but the same bug appears to be there. If I set `numBytes = 512` in the debugger (original read size), everything works as expected for the 2nd-to-last-read. On the last `ReadAsync` (the one that should return 0 because EOF has been reached), `numBytes` is `0` so we do a seemingly-needless `SeekCore(0, SeekOrigin.Current);` then a `ReadFileNative(_handle, bytes, offset, numBytes, intOverlapped, out hr);`, which causes a `hr = 87` (`ERROR_INVALID_PARAMETER`) - apparently 0 byte reads are also illegal :) I wasn't quite sure where the fix should go, but it seems like using a separate variable to determine how much to `SeekCore` and returning early when `numBytes = 0` would fix the problem. Note that using the synchronous `Read` without `FileOptions.Asynchronous` also works around this problem. Here's a minimal repro: ``` static void Main(string[] args) { Run().GetAwaiter().GetResult(); } static async Task Run() { var fs = GetStream(@""C:\Users\kedavid\Desktop\third_order.PNG""); using (var ms = new MemoryStream()) { var buf = new byte[512]; int read = 0; while ((read = await fs.ReadAsync(buf, 0, buf.Length)) != 0) { ms.Write(buf, 0, read); } } } static FileStream GetStream(string fullPath) { FileOptions FILE_FLAG_NO_BUFFERING = (FileOptions)0x20000000; return new FileStream( fullPath, FileMode.Open, FileAccess.Read, FileShare.None, 8, FileOptions.Asynchronous | FILE_FLAG_NO_BUFFERING); } ```" 13272 area-System.Security Port missing System.Security.Cryptography.X509Certificates members Address issue https://github.com/dotnet/corefx/issues/12295 Note that tests need to be added for X509Store.AddRange and .RemoveRange but if implemented like the rest of the tests they would run unreliably as they create physical artifacts on the machine.

This PR reduces it further by another ~30% from where it was after that PR. Before (10K reads / 10K writes): ![image](https://cloud.githubusercontent.com/assets/2642209/19942733/1ecfce22-a10b-11e6-890e-8038c20a8aaa.png) After (10K reads / 10K writes): ![image](https://cloud.githubusercontent.com/assets/2642209/19942743/2ddb8640-a10b-11e6-9e16-5ab07e747b54.png) Main changes: - Every read/write operation was allocating a new AsyncProtocolRequest. Without changing any of the plumbing through SslStream, we can take advantage of the fact that SslStream allows only a single read and a single write operation at a time, which means we can store and reuse an AsyncProtocolRequest instance for reading and one for writing, reusing the instances for all read/write operations on the stream. - Every read operation was boxing an Int32 result. This changes the BufferAsyncResult instance used for reads to reuse one of its existing fields to store that result, rather than storing it in the base LazyAsyncResult's object field. - Also took the opportunity to remove an unused field from BufferAsyncResult, though it doesn't change the size on 64-bit given the other fields on the base class. cc: @geoffkizer, @ericeil, @davidsh, @cipop, @benaadams, @davidfowl Contributes to https://github.com/dotnet/corefx/issues/11826 13275 area-System.Security Implement System.Security.PrincipalPermission and SecurityElement - Ports desktop code for SecurityELement and PrincipalPermission - To be used in Security.Permissions, some of the members in System.Sec.Principal.Windows need to be moved into common. - Fixes the old desktop implementation of the two functions to work in .net core.

From my perspective this problem 'suddendly' appears and I have no way of backtracking which property is causing this error message. Some background info: - we have a filter that validates models before they enter the controller action - when a validation error is found, we throw an exception and send a nice generic error response with per-field a validation message. The stack trace is also not helpful: ``` System.InvalidOperationException: Either ErrorMessageString or ErrorMessageResourceName must be set, but not both. at System.ComponentModel.DataAnnotations.ValidationAttribute.SetupResourceAccessor() at System.ComponentModel.DataAnnotations.ValidationAttribute.get_ErrorMessageString() at System.ComponentModel.DataAnnotations.RegularExpressionAttribute.FormatErrorMessage(String name) at System.ComponentModel.DataAnnotations.ValidationAttribute.IsValid(Object value, ValidationContext validationContext) at System.ComponentModel.DataAnnotations.ValidationAttribute.GetValidationResult(Object value, ValidationContext validationContext) at Microsoft.AspNetCore.Mvc.DataAnnotations.Internal.DataAnnotationsModelValidator.Validate(ModelValidationContext validationContext) at Microsoft.AspNetCore.Mvc.ModelBinding.Validation.ValidationVisitor.ValidateNode() at Microsoft.AspNetCore.Mvc.ModelBinding.Validation.ValidationVisitor.Visit(ModelMetadata metadata, String key, Object model) at Microsoft.AspNetCore.Mvc.ModelBinding.Validation.ValidationVisitor.VisitChildren(IValidationStrategy strategy) at Microsoft.AspNetCore.Mvc.ModelBinding.Validation.ValidationVisitor.VisitComplexType() at Microsoft.AspNetCore.Mvc.ModelBinding.Validation.ValidationVisitor.Visit(ModelMetadata metadata, String key, Object model) at Microsoft.AspNetCore.Mvc.Internal.DefaultControllerArgumentBinder.d__8.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Mvc.Internal.DefaultControllerArgumentBinder.d__6.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker.d__26.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker.d__25.MoveNext() ``` The only 'clue' we can derive is that ```Either ErrorMessageString or ErrorMessageResourceName must be set, but not both.``` Perhaps the exception / message can be expanded with the property name (and validator)?

Adds `HttpListener` as a new contract: System.Net.Http.Listener. This PR contains only the Windows implementation, which is based on the Win32 ""http.sys"" API. Remaining work: - Implement authentication. This will either involve sharing a fair amount of source code with System.Net.Security, or re-implementing the auth support on existing public surface from System.Net.Security. I didn't have time to explore these options enough to say which is best. For now, I've cut off auth support by throwing `NotImplementedException` in a few places. - Another couple of `NotImplementedException`s where we are trying to convert raw binary socket addresses into `SocketAddress` instances. May need new public surface in System.Net.Sockets, or just more thought than I was able to put into it. - More testing. I've only done a single ""real"" test. - Implement for Unix.

Since `System.String` in .NET is not subject to buffer overruns, etc., those APIs should be updated to call the newer system APIs which support longer file names. (No reason for new methods, or signatures, etc. -- this is a bug in the current framework; these methods should just be fixed to work and not throw that exception.) If this bug is fixed (in the main version of .NET as well), so many headaches will go away for me that it's not even funny. 13295 area-System.Reflection Consider adding GetAssemblyName() : AssemblyName to AssemblyDefinition and AssemblyReference Constructing System.Reflection.AssemblyName from metadata is a bit tricky.

We opt into ignoring the Flush in that situation. if (!_stream.CanSeek) return; FlushRead(); // User streams may have opted to throw from Flush if CanWrite is false (although the abstract Stream does not do so). // However, if we do not forward the Flush to the underlying stream, we may have problems when chaining several streams. // Let us make a best effort attempt: if (_stream.CanWrite) _stream.Flush(); Debug.Assert(_writePos == 0 && _readPos == 0 && _readLen == 0); return; } ``` Here is the [corresponding code](https://github.com/dotnet/corefx/blob/master/src/System.IO/src/System/IO/BufferedStream.cs#L324-L342) in the async version: ```cs if (_readPos < _readLen) { // If the underlying stream is not seekable AND we have something in the read buffer, then FlushRead would throw. // We can either throw away the buffer resulting in date loss (!) or ignore the Flush. (We cannot throw because it // would be a breaking change.) We opt into ignoring the Flush in that situation. if (!_stream.CanSeek) return; FlushRead(); // not async; it uses Seek, but there's no SeekAsync // User streams may have opted to throw from Flush if CanWrite is false (although the abstract Stream does not do so). // However, if we do not forward the Flush to the underlying stream, we may have problems when chaining several streams. // Let us make a best effort attempt: if (_stream.CanRead) await _stream.FlushAsync(cancellationToken).ConfigureAwait(false); Debug.Assert(_writePos == 0 && _readPos == 0 && _readLen == 0); return; } ``` Note how in the first version, we check if the stream is writable before calling `Flush` while in the second `FlushAsync` is called if the stream is readable. It looks like this is a typo, and the second version should have checked `_stream.CanWrite`. 13298 area-System.Net Test failure: System.Net.Http.Functional.Tests.HttpClientHandler_ServerCertificates_Test/NoCallback_RevokedCertificate_NoRevocationChecking_Succeeds Opened on behalf of @jiangzeng The test `System.Net.Http.Functional.Tests.HttpClientHandler_ServerCertificates_Test/NoCallback_RevokedCertificate_NoRevocationChecking_Succeeds` has failed.

But this is not the whole story. There are in fact three cases: 1. The key is already in the dictionary. Then the existing value is returned. 2. The key is not in the dictionary; the function `valueFactory` is called and generates a value. But then on rechecking, some other thread has inserted a value for that key in the meantime. In this case, the other thread's value is the one returned. The value returned by `valueFactory` is discarded. 3. The key is not in the dictionary; `valueFactory` is called; it's still not there, so the new value is inserted and returned. It needs to be a bit clearer that `valueFactory` can end up being called but its return value is not the final one returned. 13309 area-System.Net Device not configured from Dns.GetHostEntryAsync on macOS https://ci.dot.net/job/dotnet_corefx/job/master/job/osx_debug_prtest/2571/consoleText ``` System.Net.Tests.WebProxyTest.BypassOnLocal_MatchesExpected [FAIL] System.Net.Internals.SocketExceptionFactory+ExtendedSocketException : Device not configured Stack Trace: at System.Net.Dns.HostResolutionEndHelper(IAsyncResult asyncResult) at System.Net.Dns.EndGetHostEntry(IAsyncResult asyncResult) at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_debug_prtest/src/System.Net.WebProxy/tests/WebProxyTest.cs(146,0): at System.Net.Tests.WebProxyTest.d__10.MoveNext() at System.Linq.Enumerable.SelectEnumerableIterator`2.MoveNext() ``` 13310 area-System.Security Parts of the System.Security.Cryptography.* namespace missing in package: dotnet-dev-1.0.0-preview2.1-003155 I installed the dotnet-dev-1.0.0-preview2.1-003155 package on ubuntu:16.04 but it seems that parts of the System.Security.Cryptography.* namespace are missing.

We were also deriving some other things from this which didn't need to be platform specific.

Potentially though the source stream could be read from while the destination stream was written to: ```C# byte[] buffer0 = new byte[bufferSize]; byte[] buffer1 = new byte[bufferSize]; Task writeTask0; Task writeTask1 = null; int read0 = await ReadAsync(buffer0, 0, buffer0.Length, cancellationToken).ConfigureAwait(false); if (read0 != 0) { while (true) { writeTask0 = destination.WriteAsync(buffer0, 0, read0, cancellationToken).ConfigureAwait(false); int read1 = await ReadAsync(buffer1, 0, buffer1.Length, cancellationToken).ConfigureAwait(false); if (read1 == 0) { break; } await writeTask0; writeTask1 = destination.WriteAsync(buffer1, 0, read1, cancellationToken).ConfigureAwait(false); read0 = await ReadAsync(buffer0, 0, buffer0.Length, cancellationToken).ConfigureAwait(false); if (read0 == 0) { break; } await writeTask1; } if (!writeTask0.IsCompleted) { await writeTask0; } else if (writeTask1 != null) { await writeTask1; } } ``` Maybe I'm missing something, or maybe the extra heap space isn't worth it, but would this be a viable improvement? 13323 area-Infrastructure Update firewall settings on Fedora and Redhat images to allow network testing.

However, since it is not .NET CLI-specific, I figured asking here would be a better idea.) One of the things that has been driving me crazy about .NET Core is that on my Mac (running macOS Sierra, version 10.12.1), any and every file created by a .NET Core program is marked as executable (specifically, they all have the mode 711). Note that this only affects files created by a Core program; already existing files that are opened or modified remain at their existing mode. This is totally unnecessary, and furthermore complicates interoperability with programs that don’t expect every file to be executable (such as the Mac’s GUI file-management subsystem). Could this possibly be changed?

By comparison, ReaderWriterLock is about 100-1000 times as fast for the same test: ``` ............................................................. iterationsPerSecond: 4804.77 .......................................................... iterationsPerSecond: 4568.59 ................................................................ iterationsPerSecond: 5041.21 ....................................................... iterationsPerSecond: 4332.31 ........................................................... iterationsPerSecond: 4647.33 ....................................................... iterationsPerSecond: 4332.27 ..................................................... iterationsPerSecond: 4174.75 ``` I believe the issue is caused by deterministic unfairness in the spin lock. Usually, the main thread will enter its spin loop trying to acquire the write lock, before the background thread enters its spin loop trying to release the read lock. Both threads fight for the spin lock, but the main thread acquires it first. When the main thread relinquishes the spin lock to yield in the spin loop, most of the time the background thread is already in the process of yielding in-between spinning for the spin lock. So the main thread acquires the spin lock again, and so on until the spin count is maxed out. Finally, the main thread enters a wait state and releases the spin lock for long enough for the background thread to acquire the spin lock, release the read lock, and release the now-waiting main thread. One way to fix this could be to have the spin lock spin for a very short duration and fall back to a real lock." 13346 area-System.Net Dns.GetHostAddressesAsync(Dns.GetHostName()) not working on centos7 using Dns.GetHostAddressesAsync(Dns.GetHostName()) can't load local ip address on centos 7 system 13347 area-Meta Output Path not working correctly "Hey, I'm using Visual Studio 14 (VS 2015) Update 3 and I want to build a REST API based .Net Core 1, using Kestrel as the server.

System.Net.Mail is using an internal type NTAuthentication from System.Net.Security to implement NTLM, GSSAPI and Digest protocols for credential authentication. Currently I’m using reflection to get to these types, but this is not a reliable permanent solution. We have similar issues around authentication in HttpListener as well. In both cases, we need to send a response string back to the server, which is obtained by sending the challenge from server through the protocol. Currently there are 2 obstacles 1. NTAuthentication.GetOutgoingBlob/GetContextToken/GetOutoingDigestBlob API is internal 2. NTAuthentication type does not have API to choose from available protocols it supports I can see 2 options: Option 1: Make NTAuthentication type public and add to it new APIs for choosing authentication protocol. Cons: NTAuthentication is large beast and it has lots of dependencies. It hasn’t been designed to be public API. Option 2: Create new ‘SlimAuthentication’ type which is independent of server protocols (has no context whether smtp, ftp, web, etc) and implements various authentication protocols like NTLM, GSSAPI, Digest, Login (these currently exist in NTAuthentication). One thing to keep in mind, we might want to add support for newer protocols like XOAUTH2, OAUTH2 which seems to be a popular choice in many smtp servers like google, Comcast, yahoo, outlook.live, office365, etc, to this new type, hence the design should be extensible. cc @davidsh @CIPop @weshaggard @ericeil @geoffkizer @karelz 13365 area-Serialization Add Basic Tests for Serialization APIs New Added in NetStandard2.0 We want to add basic test coverage for new APIs added in NS2.0 13366 area-System.Net Add more unit tests for authentication in SmtpClient. cc @karelz @tijoytom @ericeil @davidsh 13367 area-Serialization [Impl] DCS/DCJS to Support NonSerializedAttribute and OptionalFieldAttribute 13368 area-Serialization [Impl] DCS/DCJS to Support System.Runtime.Serialization.IDeserializationCallback 13369 area-System.Security SslStream.WriteAsync() hangs on 0-byte WriteAsync on Linux and macOS "To repro, connect to any SSL endpoint (127.0.0.1:5001 in the example below) and attempt a 0-byte write: ```csharp using System; using System.IO; using System.Net.Security; using System.Net.Sockets; using System.Security.Authentication; using System.Security.Cryptography.X509Certificates; using System.Threading; namespace ConsoleApplication { public class Program { public static void Main(string[] args) { var x509certificate = new X509Certificate2(@""testCert.pfx"", ""testPassword""); using (var client = new TcpClient()) { client.ConnectAsync(""127.0.0.1"", 5001).Wait(); using (var sslStream = new SslStream(client.GetStream(), false, (sender, certificate, chain, errors) => true, (sender, host, certificates, certificate, issuers) => x509certificate)) { sslStream.AuthenticateAsClientAsync(""localhost"", new X509CertificateCollection(), SslProtocols.Tls12 | SslProtocols.Tls11, false).Wait(); sslStream.WriteAsync(new byte[0], 0, 0, CancellationToken.None).Wait(); } } } } } ``` It just hangs there.

Removes: - Dead code, unused classes/members - `System.Security.Permissions` dependency - `System.CodeDom` dependency (the package reference was removed, few types Xml still needed from CodeDom were added as internal classes under System/CodeDom instead, as removing those few would make some Xml functionalities broken and unavailable.) XSLT was basically using CodeDom for generating code from scripts (C#, JScript, etc.) inside a XSL and then compiling it into an assembly. Although the code generation part is currently available on CoreFX (still not part of netstandard), the assembly generation part is missing. This would make the XSLT functionality unavailable anyway. So, in this PR we throw `PlatformNotSupportedException` in those cases on XSLT side. cc: @danmosemsft @weshaggard @stephentoub 13371 area-System.Net Fix SslStream.WriteAsync with 0-byte write A previous fix (https://github.com/dotnet/corefx/pull/13083) added an early exit when 0-byte writes aren't supported by the underlying SSL implementation.

Sometimes you need to create a copy of an array. For example, one reason is arrays are mutable and sometimes you need to create a defensive copy, or you may want to modify some of the indices in it but keep the original array intact. There are a couple of ways of doing this right now: ### Approach 1 ```cs var array = new T[original.Length]; Array.Copy(original, 0, array, 0, original.Length); return array; ``` The downside of this approach is that it's verbose (compared to the second approach below), and can't be used in things like expression-bodied methods where you want a one-liner to clone an array. It is, however, fast since we go straight to allocating an array and calling Copy. ### Approach 2 ```cs return (T[])original.Clone(); ``` While this can be used in expression-bodied methods, the programmer has to specify `T[]` again to cast, which is prone to error since `Clone` returns an object. In addition, `Clone` is slightly slower than `Copy` and we have to make that extra typecast. ### Approach 3 (Linq) ```cs return original.ToArray(); ``` This can also be used in expression-bodied methods and is type-safe, however it is slow. Several casts are made by ToArray, then it makes virtual method calls to Count/CopyTo which do the same thing as approach 1 under the hood. ## Proposal Add a static `Array.Clone` method: ```cs namespace System { public abstract class Array : ... { public static T[] Clone(T[] array); } } ``` Usage: ```cs class Customer { Order[] _orders; public Order[] GetOrders() => Array.Clone(_orders); } ``` The implementation would be trivial and do the same thing as example 1: ```cs public static T[] Clone(T[] array) { var array = new T[original.Length]; Array.Copy(original, 0, array, 0, original.Length); return array; } ``` 13375 area-Serialization IFragmentCapableXmlDictionaryWriter not implemented by XmlBaseWriter IFragmentCapableXmlDictionaryWriter is not implemented by any class.

But the flushing support was flawed: a) we don't actually want to flush read data back to the source stream, instead wanting to instead write any read data to the destination stream, and b) even if we did, that fails for non-seekable source stream. The fix is to handle the ""flushing"" directly. If there's any read data in the buffer, we need to write that data to the destination. If there's any write data in the buffer, we need to flush that to the source. And then we can do the copy. We also need to follow the same locking scheme used elsewhere, and protect the whole operation with the stream's semaphore. cc: @ianhays, @jamesqo" 13394 area-Infrastructure Linux ARM Emulator SoftFP builds are failing frequently This is causing lots of PRs to have failed legs. ``` ./scripts/arm32_ci_script.sh: line 170: /opt/linux-arm-emulator-root/dotnet/setenv/setenv_incpath.sh: No such file or directory ``` 13395 area-Infrastructure CentOS PR legs failing with buildtools restore error ``` Restoring BuildTools version 1.0.27-prerelease-01002-04...

Fixes #5898 As suggested by @bartdesmet at https://github.com/dotnet/corefx/issues/5898#issuecomment-180063270 (CC @svick and @VSadov who also commented in that thread) this accepts the failure of the interpreter to throw non-Exception types, but throws a more explanatory exception than the mysterious `InvalidCastException` thrown. Rather than the `NotSupportedException` suggested, I went for `InvalidOperationException` that seems more apt. (There's no failure to support a method, but an inability act with the provided state). This throws on execution. Throwing on compilation would be preferable, but there would still be cases where an expression typed as `object` was thrown (allowed as long as the actual value is an exception) failed at run-time, so this is more consistent. It would certainly be possible to also throw on compilation if the type thrown is neither `Exception`-derived nor `object` if people thought that was desirable. 13409 area-Infrastructure [Question] Trying out the new corefx "Hi I'm running to an error trying out the new corefx in my project.

I expect they would look like this: // Returns the byte offset of ""target"" (presumably a field or array element within ""origin"" // wrt to the actual start of the object including the runtime-dependent object header // (i.e. we start counting from the address of the vtable pointer, not the ""first field."") IntPtr ByteOffset(object origin, ref T target) { ldarg.1 ldarg.0 sub ret } ref T AddByteOffset(object source, IntPtr byteOffset) { ldarg.0 ldarg.1 add ret } In addition to supporting DangerousCreate(), this would be needed to support non-unified empty spans since 1.

Needed to implement Span.CopyTo() efficiently. Since this is intended to be a wrapper around the ""cpblk"" IL instruction, the behavior is undefined if the ranges overlap. (This suggests Span.CopyTo() needs to handle three cases: - No overlap - Use Unsafe.CopyTo() - enjoy the perf. - Overlap one way - Use forward for loop. - Overlap the other way - Use backward for loop." 13428 area-System.Net Change NetworkStream to use base.ReadAsync/WriteAsync The base Stream has an optimized implementation for delegating to Begin/EndRead/Write. Now that NetworkStream overrides those Begin/End members, we should use the base stream's implementation rather than using FromAsync (we can put back a custom implementation if/when we can do better than the base). As the overrides exist in the contract, I've left the overrides in the implementation and just delegate directly to the base. cc: @geoffkizer, @davidsh, @cipop 13429 area-System.Runtime ValueTuple.IStructuralComparable/Equatable throws NRE instead of ArgumentNullException The following tests demonstrates this. ``` [Fact] public void IStructuralEquatable_Equals_NullEqualityComparer_ThrowsNullReferenceException() { IStructuralEquatable structuralEquatable = ValueTuple.Create(1); Assert.Throws(() => structuralEquatable.Equals(Tuple.Create(1), null)); } [Fact] public void IStructuralEquatable_GetHashCode_NullEqualityComparer_ThrowsNullReferenceException() { IStructuralEquatable structuralEquatable = ValueTuple.Create(1); Assert.Throws(() => structuralEquatable.GetHashCode(null)); } [Fact] public void IStructuralComparable_CompareTo_NullEqualityComparer_ThrowsNullReferenceException() { IStructuralComparable structuralComparable = ValueTuple.Create(1); Assert.Throws(() => structuralComparable.CompareTo(Tuple.Create(1), null)); } ``` Spun off from #13410 /cc @karelz (who can help triage this :) ) 13430 area-System.Security Correctly encode the 0-subidentifier in DerEncoder During the ECDSA-on-AppleCrypto work it was observed that two of the three supported curves didn't import successfully due to the curve OIDs being incorrect.

After this commit, CoreFX still imports several functions through APISet (GetRestrictedErrorInfo from api-ms-win-core-winrt-error-l1-1-0.dll; OpenFileMappingFromApp and VirtualAllocFromApp from api-ms-win-core-memory-l1-1-3.dll; RoGetBufferMarshaler from api-ms-win-core-winrt-robuffer-l1-1-0.dll).

I use a worker thread to relay bytes between the output of upstream process and the input of the downstream process. When `_upstream.StandardOutput.BaseStream.Read` return `0`, the worker thread dispose the `StandardInput` of the downstream process, and in that case, `Console.ReadLine()` in the downstream process is supposed to return `null`, so that the downstream process knows there is no more input and starts to wrap up and exit. This works fine in Linux when 2 processes are chained, **however, when more than 2 processes are chained, `Console.ReadLine()` in the downstream process continues to block even though the `StandardInput` of the process has been disposed.** **However, the same code works fine on windows when chaining any numbers of processes.** Repro Code ------------------------ **worker-thread-pipe: work-thread.exe** ```CSharp using System;

Unlike what was suggested in the thread for that issue, **this could be a breaking change**, that should be considered before accepting. It also makes some further changes so this is little commits now to aid examining each. They should be rebased into a single commit first if this is accepted. 427b429bb49f1f98ed621ca08b1243ef63f599b3 is the actual fix, changing a comparison of the two sets' comparers with a comparison between that of the first set and the comparer that is meant to be used by the method. Hence it's fast-path now works. ff7ef41f5ecb1485372dbf35724849fa712cdf9c improves the short-circuiting at the beginning. As well as being an improvement in itself, it moves the `Count` check out of the fast-path aiding the next step… adcf7717c0d8d119e581381cee6ff8aaa84ffaa5 uses `ContainsAllElements` instead of the loop, since that's what the loop is doing. It also covers the case were the same fast path can be used in the other direction because the second set has the appropriate comparer though the first did not. 6ec726e5c93ea613dbb59b0e83355565a0b90206 improves the non-fast-path approach for most cases (there are times when the previous code would return false sooner, but this O(n) approach should beat its O(n2) approach most of the time. 1de6790a8fde0361ba171ff5580a69b74538586e is a minor improvement to `HashSetEqualityComparer.GetHashCode()` because improving it was the original suggestion in #12560 though this minor improvement was all I could see to do there. It means empty sets don't has the same as null, and removes an operation per item that doesn't add anything to the hash quality. This also needs some test coverage. 13450 area-System.Reflection System.Reflection.TypeExtensions does not work on .NET Native I'm trying to use the `System.Runtime.TypeExtensions` package in a UWP project, and I experienced a curious behavior. My call to `Type.GetField()`. worked just fine in Debug mode, but would not work in Release Mode. Specifically, `Type.GetField()` returns null every time. Based on my research, I believe it is because `System.Reflections.TypeExtensions.dll` does not have a Default.rd.xml file containing the reflection policy for the assembly. I'm not sure if that is on purpose, or an oversight. Also not sure if that will actually solve my problem. If there is another reason this code will not work in UWP apps in release mode, there needs to be a way to ensure the package is not used in UWP apps, because developers won't know it doesn't work until they put their app in the Store.

These properties now throw a System.PlatformNotSupportedException. There is no desire to work around this in Xunit.Console.NetCore so netcore50 tests are broken for this reason until this is fixed. It's quite possible for code one is indirectly calling (and may not have control over) to call these APIs, and without being allowed to call these without crashing some code may be unusable. @weshaggard @SedarG 13458 area-System.Linq Expression Interpreter Writeback can be incorrect in the face of aliasing. Consider a byref method such as this constructor: ```C# private class ByRefNewType { public ByRefNewType(ref int a, ref int b) { ++a; b *= a; } } ``` And a variable `int x = 3` Calling `new ByRefNewType(ref x, ref x)` is equivalent to running `++x; x*=x` and hence `x` is 16. With an expression-created delegate: ```C# var del = Expression.Lambda( Expression.New( typeof(ByRefNewType).GetConstructors()[0], pX, pY), pX, pY).Compile(); int x = 3; del(byref x, byref x); ``` Then with the compiler `x` will be 16 as expected, by with the interpreter `y` will be 12 (it could conceivably end up being 4). The cause is that the interpreter doesn't have true reference types and so the aliasing is broken. I'm not sure this is feasibly fixable. It may have to be merely noted as a limitation. 13459 area-System.IO Fix StreamReader/Writer to use FileShare.Read In all of the refactorings around FileStream / StreamReader / StreamWriter, we've started accidentally passing FileShare.None instead of FileShare.Read when creating the stream used by StreamReader/StreamWriter, resulting in a bunch of test failures.

Which basically means that you cannot read a narrow range int type column into a wider range type datatype. It makes no sense.

The code in CoreLib isn't as up-to-date or complete as what we currently have in CoreFX (partially because we were trying to maintain source compatibility with desktop and partially we were only enable AppDomain bring up). This wasn't a big deal when all we had was AppDomain in play, but now that we're moving additional IO classes down we're exposing ourselves to breaks. (Either by missing fixes or missing differing behavior as the code in CoreLib uses the PAL.) While we could just share the code a little more completely there are additional issues around caching. Normalizing paths on Windows would benefit from having a single instance of the code- particularly as the same paths tend to get normalized repeatedly in succession.

The only reliable way to check if randomized hashing is enabled is to make sure that hashes generated for the same string are different for different instances of the same executable.

As more and more projects move to semantic versioning, it'd be nice to have a built-in type to handle these. Today, this fails: ```C# Version.Parse(""1.0.0-beta1""); ``` Because [`System.Version`](https://msdn.microsoft.com/en-us/library/system.version_properties.aspx) has no concept of pre-release suffixes. I'm not arguing it should be added (that's maybe a little to breaking). Instead how about a new type? `System.SemanticVersion` The *main* property most people would be interested in is the prerelease label, but other tenants of semantic versioning should be included. Comparisons being a big one. A lot of devs get this wrong on corner cases. I was looking for how to do best structure this and noticed: NuGet is already doing it. Here's their `SemanticVersion` class: ([part 1](https://github.com/NuGet/NuGet.Client/blob/4cccb13833ad29d6a0bcff055460d964f1b49cfe/src/NuGet.Core/NuGet.Versioning/SemanticVersion.cs), [part2](https://github.com/NuGet/NuGet.Client/blob/4cccb13833ad29d6a0bcff055460d964f1b49cfe/src/NuGet.Core/NuGet.Versioning/SemanticVersionBase.cs)). The API likely needs a little refinement for general use in the BCL, but is there a desire for this from others? I have use cases from parsing package versions to determining which version of Elasticsearch a client is connected to. There's a broad spectrum of semantic versioning use cases now.

I am interested in getting for example free pages available to know if my app should cache more things in memory or not. Up until now, with mono I did detect the OS info and based on that I did custom inter op for each supported system. This had the nice property that I need to release only one binary and only one tool chain to maintain. For not the only solution I see in .NetCore's current state, is to write a custom library in C with a version for each type of supported OS and than make a custom build for each OS. I feel this is a common problem that will be duplicated many times. And having the option to have a c# library that adapts to the os is a nice solution for simple problems as it does not require to set up a compile chain for each supported OS.

This PR fixes those to ensure we're not overflowing. Where I could, I simply switched to using new to allocate an array, letting the compiler handle any overflows. For the rest of the cases, I added two helpers, multiply_s and add_s, that are used to do the operations safely. Where possible, these are implemented using __builtin_mul_overflow and __builtin_add_overflow. For when we're using too old a version of clang/gcc to have those, I've copied over coreclr's ClrSafeInt (with minimal changes to get it to compile, e.g. using static_cast instead of C-style casts) and use that...

Prior to .NET Core, the construction of expression trees was using `MethodBase.GetCurrentMethod` to obtain the open generic method representing the containing method whose call's expression representation was being built. At some point, `GetCurrentMethod` was substituted for an `infoof` based approach using an expression tree to obtain the `MethodInfo` (see removed code in this PR). This causes allocation of an expression tree (with a ton of runtime checks) for every call to a `Queryable` method only to get the `MethodInfo` instance to use in the resulting expression tree. All we really need is a `ldftn` instruction. This PR replaces this approach by introducing a `CachedReflectionInfo` class containing static properties and methods to obtain (closed generic) `MethodInfo` instances for the `Queryable` methods. The (open generic) `MethodInfo` instances are cached in static fields. This is very similar to the technique we use in `System.Linq.Expressions` to cache reflection objects. The means to obtain the `MethodInfo` is using a method group conversion to a `Delegate` and a call to `GetMethodInfo` (instead of being expression based). The `CachedReflectionInfo` type was generated using a T4 template. We could check that in if we want, but we don't have an precedent for doing that AFAIK.

As a first step, I'm removing a lot of `TypeUtils.*` static method invocation syntax in favor of extension method invocation syntax. Besides improving readability of the code in various places, it also allows us to move these extension methods to more appropriate places down the line.

And with the multiple worker threads and I/O thread, the order at which operations happen are pretty much mangled together, and things just go wrong all the time. Because of this too, it's really hard to debug what's happening. I'm looking for a way to **limit both the Worker and I/O threads** to both be just 1. I need this, because it's easier this way to maintain the application, easier to reason about and debug, and save a number of threads along the way. Admittedly, I reasoned wrong with the .Net Core's async/await, which is mostly always single-threaded in other languages; so, I assumed it would also be single-threaded on .Net, but I guess I assumed completely wrong, my bad. But it's been a bad surprise for me to realize that worker threads are used by C# to make async/await happen. Now, unless things are not causing races, the project is useless now. Please suggest what do I do to make it single-threaded.

System.Net has basic name resolution and network information now. But what about a DNS client which can query any kind of DNS server? I'm currently trying to implement services with the new aspnet core stack. One common scenario with Microservices is service discovery. And one common solution for this is to use DNS. An example would be to query the consul DNS endpoint for service discovery. And this is not really easily doable today. There are certain implementations available for the .NET world, but those are pretty basic and mostly not maintained repositories and/or they are not supporting netstandart. Are there any plans to add something like that? Or, if I'm just missing something, any hint?

Here's a profile of an app that just does this a thousand times: ```new Uri(""http://test.com"")```: ![image](https://cloud.githubusercontent.com/assets/2642209/20239952/96b6b7bc-a8da-11e6-8b98-45fed7685072.png) As can be seen, in addition to the 1000 Uri allocations, there are also 1000 string allocations and 1000 char[] allocations. The string allocations are coming from https://github.com/dotnet/corefx/blob/9eaf364b8ca8180bace20aab188b1efe6a55835f/src/System.Private.Uri/src/System/Uri.cs#L3933 , where a string is being allocated purely to look up the value in a dictionary. We should be able to avoid that for common schemes by just comparing the data for common schemes (e.g. http, https, ws, wss, etc.) and getting the syntax object directly. In fact, it looks like this may already be done on 32-bit, just not on 64-bit: https://github.com/dotnet/corefx/blob/9eaf364b8ca8180bace20aab188b1efe6a55835f/src/System.Private.Uri/src/System/Uri.cs#L3639 .

There are various ways this allocation could be avoided, e.g. at the expense of a pass through the string, checking to see whether anything needs unescaping, and only falling through to the allocation and the rest of the method if it does." 13624 area-System.Reflection HandleCollections should have an indexer I have a use case where I need to index into methods and fields on a `TypeDefinition`. `FieldDefinitionHandleCollection` and `MethodDefinitionHandleCollection` don't have an indexer, so the only option seems to be to get an enumerator and call `GetNext()` method *N* times to get *N*th member. `GenericParameterHandleCollection` or `GenericParameterConstraintHandleCollection` already have an indexer. This seems like an API inconsistency. Unless there's a particular reason why the other `HandleCollections` can't have it, the indexer should be added to all of them. We can make them implement `IReadOnlyList` while we're at it too. 13625 area-System.Collections Performance improvements in System.Collections.Generic.Dictionary Use local variable with size/length of buckets array in cleaning. I wrote simple test for for when i use local variable vs length with BenchmarkDotNet. Local variable is about 30-50% faster. This optimization is applying in Initialize and Resize. In this method is size already in local variable. It should be applying in Clear but here it must first assign to local variable and it's add one extra variable on stack. Second optimization is applying in Insert method where i reduce one local variable via reusing. 13628 area-System.Linq Recognize Skip/Take chains on lazy sequences. I added a new `EnumerablePartition` class that lets us now recognize patterns like `Take.Skip`, or vice versa, for lazy sequences. We also remove a layer of indirection from some common operations following these methods, e.g. `Take.ToArray`, `Skip.ToArray`, etc. Perf results can be found [here](https://gist.github.com/jamesqo/07eb6b38d69431d7270900e3a7519c32); test code [here](https://github.com/jamesqo/Dotnet/blob/502e3c302575d04824e7337bec4d635abc8dc548/Program.cs).

This PR significantly reduces the number and size of allocations in HttpClient. Some of the changes are in HttpClient itself, and thus apply to any handler/platform, while some are specific to the Windows implementation. Analysis of the following program was used to drive the changes. It simply downloads the contents of httpbin.org, dumping it to a null stream, 1000 times: ```C# using System; using System.IO; using System.Linq; using System.Net.Http; using System.Threading; using System.Threading.Tasks; class Program { static void Main() { var client = new HttpClient() { Timeout = Timeout.InfiniteTimeSpan }; var uri = new Uri(""http://httpbin.org""); Task.WaitAll(Enumerable.Range(0, 1000).Select(async _ => { using (Stream responseStream = await client.GetStreamAsync(uri)) { await responseStream.CopyToAsync(Stream.Null); } }).ToArray()); } } ``` Before these changes, these allocations show up (divide each line by 1000 to get the appx per iteration count): ![image](https://cloud.githubusercontent.com/assets/2642209/20248813/c3e13a5c-a9b9-11e6-987d-7ce6759811a5.png) That's ~127 allocations and ~8518 bytes per iteration. After these changes, these allocations show up: ![image](https://cloud.githubusercontent.com/assets/2642209/20248823/db254532-a9b9-11e6-9fc6-ad150bfb4cd0.png) That's ~60 allocations and ~4449 bytes per iteration. For this particular scenario then, this represents an ~50% reduction in both number and size of allocations. Other scenarios will benefit from many of these changes, but will also have their own additional allocations that can likely be reduced. I've kept the changes isolated in their own commits. The commit descriptions provide more details, but the main changes: - Added more headers to the HttpKnownHeaderNames table. Even for a basic site like httpbin.org, there were headers coming back that are commonly used but weren't in our table. The table now contains all of the response entries that kestrel has in its similar optimization as well as some additional headers listed as common response headers on wikipedia. - Significantly reduce the number of tasks and task completion sources used in WinHttpHandler. Every stage of its lifecycle was represented with its own TCS/Task. Instead, I added a common ""RendezvousAwaitable"", a reusable awaitable object that can be produced to via SetResult/SetException/SetCanceled just like TaskCompletionSource and can be awaited to consume the results, but which can be allocated once and reused any number of times (this is something I we may want to consider exposing publicly from the BCL at some point; it's quite handy and helpful). I then use that throughout WinHttpHandler, cutting back on the number of tasks used and on the size of the state object used to hold them. As part of this, I added a CopyToAsync implementation to WinHttpResponseStream; we can subsequently do something similar for the CurlResponseStream (that one should be easier, too, as libcurl is already a push-based model, which maps nicely to CopyToAsync). - Optimized common cases (often via lazy-initialization) where allocations were being done for empty cases, e.g. allocating an enumerator when there weren't any headers to enumerate, allocating cookie-related state when there weren't any cookies, allocating a TransportContext object even when it wouldn't be needed, etc. - Avoiding allocating a CancellationTokenSource per request when the user didn't provide a CancellationToken and when no timeout is set. This helps avoid not only the CTS allocation itself, but also the state within the CTS that's allocated on first use. - Removing unnecessary allocations, like a lock object used per state object, when the state object itself can be used for locking. - Using a buffer from ArrayPool to avoid allocating a new char[] to store all of the response headers - Avoiding the need for allocating a ReadOnlyStream to wrap the WinHttpResponseStream, which is already read-only. - Reducing the sizes of async state machines by being a bit more thoughtful about what locals will end up getting promoted to fields in the state machine. - Avoiding async state machine objects altogether for simple cases where a ContinueWith is sufficient and less expensive.

Now when I gather string from many parts, I gather each part into separated StrindBuilder (for example in different threads for speed) and then when I gather all parts to one StringBuilder, the standard library made many copy operations to convert each StringBuilder to string and then to copy each string to StringBuilder chunks. It is bad because after each part is appended to final StringBuilder, it is no longer used or changed, it is just collected by garbage. So it would be great just append chunks from one StringBulder to other without copy them two times. So to fast append second StringBuilder to first StringBuilder, it can just append chunks from second to first. After that it can set CopyOnChange flag in common chunks of first and second StringBuilders. Later if CopyOnChange chunk should be changed (very rare unusual case) it should be duplicated before changing. 13640 area-Infrastructure [ARM/Linux] Error during cross building for arm32 "Build environment: x64 Ubuntu 14.04 Build target: arm32 commit: ece35f9 Build option: release, skiptests, enable outloop error log in msbuild.log ``` 1266>/nfs/rbp3/corefx/layout/layout.proj(74,5): error MSB3030: Could not copy the file ""/nfs/rbp3/corefx/bin/Windows_NT.x64.Release/Native_aot/clrcompression.dll"" because it was not found. .....

However, this property is not present on the version of `SqlConnection` provided in the System.Data.SqlClient NuGet package, including the latest preview v4.3.0-preview1-24530-04. In case it's an important detail, the project in question is a library project targeting 'netstandard1.6'. The lack of the `AccessToken` property makes it difficult, if not impossible, to support modern directory-based auth scenarios for Azure SQL DB while also targeting .NET Standard (I have not attempted to use the connection string-based AAD options, but for various reasons those would not be applicable for my project). I have yet to find a workaround other than setting the target framework to 'net46', which I would like to avoid except as a last resort. 13662 area-System.Net Add SocketAsyncEventArgs test for 0-byte receive I got a report that 0-byte receives weren't working correctly, which led me to find that we don't have any tests for it.

(This is a rather strange allowance, but it allows a parallel to comparison with null literal in C#).

This is a quick helper, but we can do better performance-wise. First, FromAsync needs to take the object state provided by the user and pass that through to the begin method as its object state. That means that FromAsync has no way to get additional state into the body of the end method, which means it ends up allocating a delegate and a closure. FromAsync does benefit from being able to avoid creating a TaskCompletionSource, but the cost of a TCS is much less than the cost of a delegate and a closure. Second, the per-call AsyncCallback allocation ends up defeating a cache inside of Socket, which means every call ends up needing to allocate an internal CallbackClosure object. Third, several of these methods need to pass additional state through in order to handle refs on the begin method and getting that data into the out (there's also a race conditoin bug in the current handling of this). That meant allocating an additional object[] and in some cases boxing value types. We can improve this by just writing the code out manually using TaskCompletionSource directly. We do have to allocate the TCS, but we save on the delegate and closure allocations, we avoid extra delegate invocations, we avoid extra allocations to handle those ref cases, etc. In a test that repeatedly asynchronously writes to one socket with SendAsync and reads from another with ReceiveAsync, this changes reduces number of allocations by ~20% and allocated bytes by ~25%. cc: @davidsh, @cipop, @geoffkizer 13685 area-System.Net Remove a reference field from OverlappedAsyncResult It's only relevant to async ReceiveFrom, so put it on a derived class used there. cc: @davidsh, @cipop, @geoffkizer 13687 area-System.Security Oversights in X509Certificates namespace Small omissions from X509Certificates ns. `X509CertificateCollection` needs to derive from `CollectionBase` `X509CertificateCollection.X509CertificateEnumerator` needs to be `new` ie ``` public new X509CertificateCollection.X509CertificateEnumerator GetEnumerator(); ``` Also this method is missing. ``` public class X509Chain : IDisposable { public static X509Chain Create(); } ``` /cc @steveharter 13688 area-System.Security Default is missing from SslProtocols ``` namespace System.Security.Authentication { public enum SslProtocols { Default = 240, } } ``` 13689 area-Serialization readonly on two Formatter fields does not match NS2.0 These two fields were marked `readonly` in Core, but were not `readonly` in the full Framework, and thus not in Standard.

I made an optimization in #13158 to make `ImmutableArray.InsertRange` for well-known collections, including arrays, lists, and `ImmutableArrays`. Unfortunately, the optimization for arrays had to be reverted. For context, see https://github.com/dotnet/corefx/pull/13158#discussion_r86702932 There are a few possible workarounds for this: 1) Use a for-loop, which will be less efficient than `Array.Copy`. 2) Check that the `T[]` is really of type `T[]` by testing `array.GetType() == typeof(T[])` beforehand, and use `Array.Copy` if so, or else fall back to a for-loop. 3) Just use `Array.Copy`, and break the existing scenario. I personally think option 3 is reasonable. It's technically a breaking change, e.g. the test app I posted in my comment would no longer work: ```cs class Program { static void Main(string[] args) { int[] ints = new[] { 1, 2, 3 }; uint[] uints = (uint[])(object)ints; var immutableUints = ImmutableArray.Create(new[] { 1u, 2u, 3u }); immutableUints.AddRange(uints); // Works now; with changes, will throw ArrayTypeMismatchException } } ``` But considering that today `ImmutableArray.Create((uint[])(object)new[] { 1, 2, 3 })` also throws an exception, indicating these types of arrays are not really supported, it seems reasonable to make this change. cc @AArnott 13696 area-System.Linq Linq: Where(pred).First should not be faster than First(pred) Related StackOverflow question: http://stackoverflow.com/q/8663897/4077294 Because `Where` is specialized internally for different types, e.g. arrays and lists, we can iterate through them directly in `MoveNext` and avoid some virtual dispatch. `First(pred)`, on the other hand, does not do any such specialization. This means that `array.Where.First` will be faster than `array.First` if the first element that matches the predicate is far up in the sequence. We may want to share code between `Where.First` & `First`, i.e. by doing a bunch of typecasts in `First` and calling some function that statically receives the source as an array/list, & then also have the specialized iterators call through to those functions. Same applies for certain other functions that accept predicates, such as `Count`. 13699 area-Serialization DCS/DCJS does not Support ExtensionDataObject in ReflectionOnly mode Fix for #12767 made DataContractSerializer and DataContractJsonSerializer support ExtensionDataObject.

Fix #13691. 13720 area-System.Net Reduce allocations in HttpClient.GetString/ByteArrayAsync "Today, HttpClient.GetStringAsync and GetByteArrayAsync copy all of the response data to a MemoryStream. For strings, that buffer is never exposed, so it ends up being temporary garbage. For byte arrays, the data is extracted from the MemoryStream with ToArray, which means double the allocations. This commit does three things: - It introduces a helper Stream based on ArrayPool, where all buffers come from the shared pool. - GetStringAsync uses that stream as the target, such that the byte[]s used are recycled with the pool, avoiding per-request allocations. - GetByteArrayAsync uses that stream as the target if a content length couldn't be determined, so that the byte[]s incurred as the stream grows are recycled. And if a content length can be determined, it uses a MemoryStream and then returns that MemoryStream's buffer directly to the caller, avoiding the extra buffer allocation and copy. As an example, this program is concurrently downloading a 12K web page a thousand times: ```C# using System; using System.IO; using System.Linq; using System.Net.Http; using System.Threading; using System.Threading.Tasks; class Program { static void Main() { var client = new HttpClient() { Timeout = Timeout.InfiniteTimeSpan }; var uri = new Uri(""http://localhost:8080/""); Task.WaitAll(Enumerable.Range(0, 1000).Select(_ => client.GetByteArrayAsync(uri)).ToArray()); } } ``` Before the change the program allocates ~27.5MB, and after the change it allocates ~16.2MB (~40% reduction). Similarly, if the GetByteArrayAsync above is changed to GetStringAsync, before the change the program allocates ~39.5MB, and after the change the program allocates ~28.8MB (~30% reduction).

Failure to find a debug property for any public property is considered a failure, with the explicit exceptions of `ArgumentCount` and `ExpressionCount`. Similar tests for `BindingRestrictions`' proxy, though with differences as it doesn't have the same one-to-one mapping. Debugger proxies not included: 1. `ExpandoObject`'s keys and values collections. Will do this after #13595 fixes `ExpandoObject`'s dynamic behaviour, #13634 tests it directly, and probably some more tests on `ExpandoObject` itself (maybe at the same time. 2. `InstructionArray` and `InstructionList`. As there's no way to peek through the delegate to the instructions (is there?) testing this would require some particularly artificial use of reflection to create the llists, as well as their proxies.

This means the static Create methods added to S.S.C.Primitives throw PNSE. CryptoConfig could not be placed in S.S.C.Primitives as it wouldn't be able to reference Oid\S.S.C.Encoding without an cyclic assembly reference.

If it is Success or IOPending - it will return true. `WSARecv` will not return SUCCESS for IOCP-based call unless `SetFileCompletionNotificationModes` was called for the socket setting the flags above. So in default operation mode check for inequality to `SocketError.Success` is harmless (but redundant) and is always true. Once you set notification modes though, `WSARecv` may return SUCCESS in case of sync completion and then it won't invoke callback on SAEA and per code above will return true. Proposal is to change behavior of `ReceiveAsync` and other IOCP-based methods to support synchronous completion. The code above would change as follows: ``` C# if (socketError == SocketError.Success) { e.FinishOperationSuccess(SocketError.Success, bytesTransferred, flags, completedSynchronously: true); retval = false; } else { socketError = (SocketError)Marshal.GetLastWin32Error(); if (socketError == SocketError.IOPending) { retval = true; } else { e.FinishOperationSyncFailure(socketError, bytesTransferred, SocketFlags.None); retval = false; } } ``` Another change not shown here is to `SocketAsyncEventArgs.FinishOperationSuccess`, adding parameter `bool completedSynchronously` that if true would skip raising SAEA.Completed event. This change and support for SetFileCompletionNotificationModes yield significant performance improvement for scenarios with high throughput over a small number of sockets. Let me know if the change is something you can consider to take and I'd post a PR." 13753 area-Infrastructure Upgarding nuget package of .NETCoreApp breaks debugging "Creating a new console .NET core application: After upgrading the .NET Core App package.

To mitigate concerns around returning a buffer to the pool that's still in use, it tracks active async operations and only returns the buffer when disposing the stream if there aren't any active async operations. That tracking was already in place, I just tweaked it slightly. (@ianhays, there is now some duplication in this checking; previously it was checking the active operation flag separately from using an interlocked to increment it, and I changed that latter portion to throw if the interlocked shows the usage to be invalid, but I left the former in place in case we're really concerned about the order that exceptions get thrown in... if we're not, we should clean that up.)

Add API to convert a `StringComparison` to a `StringComparer`, to avoid bunch of switch-statements in user code (see 'Motivation' section below). 2. Add `string.GetHashCode(StringComparison)` API, to make it easier/more discoverable to get the culture-dependent, case-insensitive, etc. hash of a string. Currently, you have to do `StringComparer.XXX.GetHashCode(str)`, which is verbose & hard to find. ```c# public class StringComparer { public static StringComparer FromComparison(StringComparison comparisonType); } public sealed class String { public int GetHashCode(StringComparison comparisonType); } ``` ### Motivation If someone has a variable comparison they don't have to do a bunch of switch-cases (we'll do them instead): ```c# public static StringComparer FromComparison(StringComparison comparisonType) { switch (comparisonType) { case StringComparison.Ordinal: return StringComparer.Ordinal; case StringComparison.OrdinalIgnoreCase: return StringComparer.OrdinalIgnoreCase; ... } } ``` For more background: See @stephentoub's suggestion in https://github.com/dotnet/corefx/issues/8034#issuecomment-261519913 cc @justinvp @Elion 13801 area-System.Drawing Drawing primitives cleanup These are tiny commits to make it easier to just undo one during review.

To use it, you write code like: ```c# var textElementEnumerator = StringInfo.GetTextElementEnumerator(s); while (textElementEnumerator.MoveNext()) { string textElement = textElementEnumerator.GetTextElement(); // process textElement here } ``` This makes the API unfamiliar and inconvenient to use. I propose that a new API based on `IEnumerable` should be added. ## Proposed API ```c# class StringInfo { public static IEnumerable GetTextElements(string str); public static IEnumerable GetTextElements(string str, int index); } ``` The new methods work like the old methods, except that they return generic enumerable instead of enumerator. ## Usage The new API could be used just like any other `IEnumerable`, e.g.: ```c# foreach (var textElement in StringInfo.GetTextElementEnumerator(s)) { // process textElement here } ``` ## Open questions * Returning `IEnumerable` means information about `ElementIndex` is lost. Is that information useful enough to use something like `IEnumerable<(string textElement, int index)>` instead? (Possibly using a custom `struct` instead of a tuple.) * Each text element `string` is a substring of the input `string`. Would it be worth waiting for spans and use `IEnumerable>` instead? * Returning `IEnumerable` requires allocating that `IEnumerable`. Would it be worth to return struct enumerable with struct enumerator instead, which would avoid the allocation when used in `foreach`? 13827 area-System.Xml XsltCompiler.Tests project fails many tests when UI language is not ENU I have many failed tests in next projects. msbuild.err ``` 541:5>C:\Users\Alex\Documents\Home\corefx\Tools\tests.targets(254,5): error : One or more tests failed while running tests from 'System.Collections.Tests' please check log for details!

I have taken all that feedback into account to make this new proposal, which only consists in the following inclusions: ```C# public const decimal PI_dec = 3.1415926535897932384626433832m; public const decimal E_dec = 2.7182818284590452353602874713m; public decimal Pow(decimal x, decimal y); public decimal Sqrt(decimal d); ``` The algorithms of the new `Pow`/`Sqrt` overloads are expected to exclusively rely on the `decimal` type (i.e., no conversion to/from `double`/`float` at any point). In fact, I have recently finished the first version of an open source library (NumberParser) precisely including two methods fulfilling that requirement. Note that, additionally to [its properly-commented C# source code](https://github.com/varocarbas/FlexibleParser/tree/master/all_code/NumberParser/Source), I also wrote [detailed explanations about the implementation of those two methods](https://varocarbas.com/fractional_exponentiation). I am even planning to write much more explanations about this whole code within the short term. Anyone can use this library and test the aforementioned methods (```Math2.PowDecimal```/```Math2.SqrtDecimal```) to get a feeling of what the proposed new overloads might deliver. In any case, the following ideas should be clear: - These methods rely on a custom class (```Number```), whose main goal is allowing to deal with very big ranges of values. It is certainly much less efficient than the native ```decimal```/```double``` types. - In case of deciding to go ahead with this proposal and additionally to perform the aforementioned adaptation, I am also planning to further optimise these algorithms. Nevertheless and even in the best scenario, the new ```decimal``` version is likely to be slower than the ```double``` one (perhaps also in case that it would also include the corresponding conversions from/to ```decimal```, although I am still not sure about this). Its strongest point will be accuracy, rather than speed. - The current version of this approach accounts only for the first 25 decimal digits of the exponent (note that the `decimal` type can deal with up to 28). In principle, I don’t see this as a problem, although I look forward to your opinions on this front. In summary, the new overloads are expected to avoid the floating-point/limited-precision problems associated with converting from/to ```double```; to deliver accurate results (up to `5e-28m`) not constrained by simplifications/floating-point restrictions. As highlighted in the review of my previous proposal, there is a backwards-compatibility problem associated with adding these new overloads without any further modification: calls relying on implicitly convertible types will stop working. For example: ```System.Math.Pow(1, 10) ``` (i.e., two ```int``` variables implicitly converted to ```double```) works fine now, but will not work after just adding the proposed ```decimal``` overload. There are two ways to address this problem: - Including additional overloads with all the implicitly convertible types, consisting in simple calls to the `double` ones. For example: ```C# public static double Pow(int x, int y) { return Pow((double)x, (double)y); } ``` - Adding two new methods rather than overloads to existing ones (e.g., ```PowExact```/```SqrtExact```). In principle, the first alternative seems better, although it would imply accounting for a quite relevant number of scenarios (e.g., `Pow(int x, int y)`, `Pow(int x, long y)`, `Pow(int x, ulong y)`, etc.). 13836 area-System.Net Fix Supported/UnsupportedSslProtocols tests with SslProtocols.Default Fixes https://github.com/dotnet/corefx/issues/13833 cc: @danmosemsft, @cipop 13837 area-Meta 100% CPU load After upgrade to 1.1.0 I have an issue then dotnet process start to load CPU on 100%.

Fixes #13840 with the exception of two types covered in #13839 so the fix can live with appropriate tests. 13842 area-System.Linq Add Enumerable.SkipLast, TakeLast to get the last N elements of a sequence. "## Background Currently, Linq does not offer an API for getting the last N elements of a sequence. This has resulted in no less than [5 StackOverflow questions](https://www.google.com/search?q=skip+last+n+elements+of+enumerable&rlz=1CAACAH_enUS678US678&oq=skip+last+n+elements+of+enumerable&aqs=chrome..69i57.4760j0j7&sourceid=chrome&ie=UTF-8) (with ~300 votes) popping up as the first result when you Google ""skip last n elements of enumerable."" ## Proposal We should add `SkipLast` and `TakeLast` to Enumerable, which will skip/take the last N elements of the sequence, respectively. If there are less than N elements, `SkipLast` will return an empty sequence, and `TakeLast` will return a sequence with contents equivalent to the original enumerable. ```cs namespace System.Linq { public static class Enumerable { public static IEnumerable SkipLast(this IEnumerable source, int count); public static IEnumerable TakeLast(this IEnumerable source, int count); } public static class Queryable { // Lots of existing methods for parity with Enumerable public static IQueryable SkipLast(this IQueryable source, int count); public static IQueryable TakeLast(this IQueryable source, int count); } } ``` ### Remarks - In `SkipLast` instead of evaluating the whole thing at once, we will read in the first `count` items into a circular buffer. Then we will interleave between yield returning the oldest element & overwriting that with a new one. - In `TakeLast` we will still evaluate the whole sequence during the first iteration, but again maintain a circular buffer of length `count` and overwrite the oldest elements with newer ones. ### Original (incorrect) - Implementation remarks These overloads will have subtly different semantics from `Skip` and `Take`. Since for lazy enumerables we can't determine the count of the sequence in advance, we will have to capture it into an array during our first iteration (like `Reverse` does today), then skip/take the last N items from that array between yields. ```cs public static IEnumerable SkipLast(this IEnumerable source, int count) { var array = source.ToArray(); for (int i = count; i < array.Length; i++) { yield return array[i]; } } ``` As a result, these will have different outputs: ```cs int[] a = { 1, 2, 3, 4, 5 }; foreach (var item in a.Skip(3)) { a[4] = 10; Console.WriteLine(item); // 4 10 } a[4] = 5; foreach (var item in a.TakeLast(2)) { a[4] = 10; Console.WriteLine(item); // 4 5 } ``` Another consequence is that this will lead to more allocations for lists/arrays. Perhaps this is worth it for added convenience, though." 13843 area-System.Linq System.Dynamic.BinaryOperationBinder Tests Add tests exercising the `BinaryOperationBinder` class.

Caller must know NOT to call this with a `T` containing references. @jkotas @AtsushiKan @benaadams @jamesqo @omariom **UPDATE**: For API review, basically the choice is whether to add any of the below or perhaps both. Or in any shape that FXDC finds suitable. The below has been chosen to fit existing API definitions. The functionality is needed for `Span` and other `ref` based scenarios for e.g. optimal performance. ```csharp void CopyBlock(ref T destination, ref T source, int elementCount); void CopyBlockUnaligned(ref T destination, ref T source, int elementCount); ``` OR ```csharp void CopyBlock(ref byte destination, ref byte source, uint byteCount); void CopyBlock(ref byte destination, ref byte source, UIntPtr byteCount); void CopyBlockUnaligned(ref byte destination, ref byte source, uint byteCount); void CopyBlockUnaligned(ref byte destination, ref byte source, UIntPtr byteCount); ``` I will change the implementation once I get word of the result of the API review. If needed I can create a separate issue for API review, but since this change is rather small I am hoping to keep it here. Personally, I think adding both would be great. Not the least since the generic version covers the most common use case for the work I do, and because it fits `Span`. 13849 area-System.Security System.Security.Cryptography.Algorithms.Tests fail ExpectedSignature_SHA1_384 test On my Windows 2012 server `System.Security.Cryptography.Algorithms.Tests` project fail `ExpectedSignature_SHA1_384` test with exception `Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: Requested operation is not supported`. 13850 area-System.Security System.Security.Cryptography.Cng.Tests fails two tests On my Windows 2012 server `System.Security.Cryptography.Cng.Tests` project fails two tests: `ExpectedSignature_SHA1_384` and `RSACng_Ctor_UnusualKeysize_384` with the same exception `Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: Requested operation is not supported`. 13851 area-System.Linq System.Dynamic.UnaryOperationBinder Tests Add tests exercising the `UnaryOperationBinder` class.

In some cases, potentially hundreds of these may be created for a single request, and so we want them to be pretty slim. We've created a few specialized types of our own to meet this need, but the canonical case is something like [AttributeDictionary](https://github.com/aspnet/Mvc/blob/dev/src/Microsoft.AspNetCore.Mvc.ViewFeatures/ViewFeatures/AttributeDictionary.cs). There's a ton of boilerplate associated with implementing `IDictionary<,>` and so we're not thrilled with implementing one of these each time we want to optimize something. We're also not necessarily married to `IDictionary<,>` as the primary contract. That's what there is, so that's what we're using to avoid reinventing the wheel (while reimplementing the wheel).

"Interpreter can throw and catch reference types not derived from Exception. If the exception escapes the expression it will be a `RuntimeWrappedException`. Provides a better fix to #5898 than #13408. At the beginning of the discussion of #5898 the idea that ""Possibly something could be done by manipulating `RuntimeWrappedException`"" was suggested, but not much came from that idea as that type wasn't available within corefx. Having the interpreter throw `InvalidOperationException` for non-exceptions and just accepting its inability to catch them was the best that could be done, so #13408 did that. However, in the meantime #11930 had made `RuntimeWrapperException` available to use. And with it the interpreter can be made to match the compiler entirely. The compiler also seems to unwrap any RWE so there isn't a need to track whether an RWE had been created internally or not (someone would have to be very foolish to only realise that after writing code to do such tracking and then having to delete it again…). So, with this PR both interpreter and compiler are akin in: 1. Being able to throw any reference type. 2. Being able to catch any reference type. 3. Being able to catch a non-exception reference type from a call into another assembly, whatever that assembly's `RuntimeCompatibilityAttribute` settings. 4. If a `RuntimeWrapperException` originating from outside the expression is thrown within it, they can catch the wrapped object. 5. If a non-exception is thrown by the expression, it can be caught in the invoking code as a `RuntimeWrapperException`. cc @VSadov @bartdesmet @svick (The only remaining difference in exception handling between the two is now that the compiler can't do fault and filter blocks)." 13881 area-System.Numerics Unable to cast object of type 'System.Numerics.BigInteger' to type 'System.Decimal'.

It uses a shim that opens the libssl shared library with versioned so name specific for the platform and gets all needed API function pointers using dlsym and stores them in global variables. The calls to those APIs are then redirected through these pointers. I have verified that our code doesn't access any data members in structures with layout that can vary based on compilation options of the OpenSSL and that can have variable offset. The only direct access of this kind that we were using, the X509::sha1_hash, was replaced by call to recompute the hash, based on @bartonjs suggestion. There are couple of functions that we use and that don't have to exist in the libssl when it is compiled with particular options. These were handled at the build time before, now I have also added runtime handling of this case. Finally, I have added verification of the System.Security.Cryptography.Native.OpenSsl.so to make sure it doesn't have any undefined symbols. This could happen if someone adds usage of a new OpenSSL API and doesn't add its name to the opensslshim.h.

What is missing is an interface to query actual DNS servers (custom endpoints/ports) and get more information then just the IP or local host name. # Use Case One use case could be accessing service discovery (e.g. Consul) to ask for available services by name via DNS: A local Consul DNS endpoint runs on port 8600 and you'd either query with qtype `SRV` or `A`. To query for a service by name in consul, you use `.service.consul`. Example query and answers with dig asking for the consul service itself: ``` $ dig @127.0.0.1 -p 8600 consul.service.consul SRV ;; QUESTION SECTION: ;consul.service.consul. IN SRV ;; ANSWER SECTION: consul.service.consul. 0 IN SRV 1 1 8300 hostname.node.dc1.consul. ;; ADDITIONAL SECTION: hostname.node.dc1.consul. 0 IN A 127.0.0.1 ``` The SRV answer gives me the port the service instance is running on, the additional answer gives me the IP address. The result can contain multiple instances. # Why another API? There are a few other implementations for .NET today, but none of which are really maintained as far as I know nor do they have support for netstandard1.x. # Proposed API ## Usage Creating a lookup client with different overloads: ``` CSharp // create a client using the dns server configured by your network interfaces var lookup = new LookupClient(); // create a client using a DNS server by IP on default port 53 var lookup = new LookupClient(IPAddress.Parse(""127.0.0.1"")); // create a client using a DNS server on port 8600 var endpoint = new IPEndPoint(IPAddress.Parse(""127.0.0.1""), 8600); var lookup = new LookupClient(endpoint); ``` Using the client to query for standard qtypes: ``` CSharp // query for google.com with qtype ANY DnsQueryResponse result = await lookup.QueryAsync(""google.com"", QueryType.ANY); // qtype A and explicitly setting the qclass of the query DnsQueryResponse result = await lookup.QueryAsync(""google.com"", QueryType.A, QueryClass.IN); // reverse query the host name of an IP Address using arpa DnsQueryResponse result = await lookup.QueryReverseAsync(IPAddress.Parse(""192.168.1.1"")); ``` The result in all cases would contain the response header information, the list of resource records and the question. ## API LookupClient: ``` CSharp public class LookupClient { // dis/enables caching of responses (TTL would be driven by the server's response) bool UseCache { get; set; } public LookupClient(); public LookupClient(params IPEndPoint[] nameServers); public LookupClient(params IPAddress[] nameServers); public LookupClient(DnsMessageHandler messageHandler, ICollection nameServers) public Task QueryAsync(string query, QueryType queryType); public Task QueryAsync(string query, QueryType queryType, QueryClass queryClass); public Task QueryAsync(string query, QueryType queryType, CancellationToken cancellationToken); public Task QueryAsync(string query, QueryType queryType, QueryClass queryClass, CancellationToken cancellationToken); public Task QueryReverseAsync(IPAddress ipAddress); public Task QueryReverseAsync(IPAddress ipAddress, CancellationToken cancellationToken); } // message handler could be implemented with UDP or TCP, or cool channels or what ever ;) public class DnsMessageHandler { public Task QueryAsync(IPEndPoint server, DnsRequestMessage request, CancellationToken cancellationToken); // processes the query and generates the actual data to send to the server public virtual byte[] GetRequestData(DnsRequestMessage request) // processes the raw response data public virtual DnsResponseMessage GetResponseMessage(byte[] responseData) } // the request message public class DnsRequestMessage { public DnsRequestHeader Header { get; } public DnsQuestion[] Questions { get; } } // the request header public class DnsRequestHeader { public DnsHeaderFlag HeaderFlags {get;} public int Id { get; } public DnsOpCode OpCode {get;} public int QuestionCount { get; } public bool UseRecursion {get;} } // Question contains the actual query, used by response and request public class DnsQuestion { public DnsName QueryName { get; } public QueryClass QuestionClass { get; } public QueryType QuestionType { get; } // the response object returned by the lookup client public class DnsQueryResponse { public IReadOnlyCollection Additionals { get; } public IReadOnlyCollection AllRecords public IReadOnlyCollection Answers { get; } public IReadOnlyCollection Authorities { get; } public string ErrorMessage { get; } public bool HasError { get; } public DnsResponseHeader Header { get; } public IReadOnlyCollection Questions { get; } } // see https://tools.ietf.org/html/rfc1035#section-3.2.2 and 3.2.3 public enum QueryType : short { A = 1, NS = 2, ... } // see https://tools.ietf.org/html/rfc1035#section-3.2.4 public enum QueryClass : short { IN = 1, CS = 2, CH = 3, HS = 4 } ``` There are some more types like return codes / errors etc. ### RFC References Base RFC https://tools.ietf.org/html/rfc1035 Request and response header share the same RFC https://tools.ietf.org/html/rfc6895#section-2.

Sometimes, however, you don't want the same value repeated N times but the same function called N times. For example: ```cs var r = new Random(); var randomNumbers = Enumerable.Repeat(r.Next(), 100); // Newbie: Why isn't this working? var reallyRandomThisTime = Enumerable.Repeat(_ => r.Next(), 100); // That does the trick! ``` The current workaround for this is to do something like `Enumerable.Range(0, size).Select(_ => r.Next())`, which is not really as readable. I [do it myself](https://gist.github.com/jamesqo/25e02482e5a9257b52ee3b6c91bfc556#file-skipregression-cs-L17) all the time in my benchmarks for example, & you can see such examples on [StackOverflow](http://stackoverflow.com/a/4903861/4077294). ## Proposal We should add an overload of `Repeat` accepting a `Func`. This function will be evaluated N times as the enumerable is iterated. The input to each invocation of the function will be the result of the last invocation; the input to the first invocation will either be a user-specified seed, or `default(T)` if no seed was specified. ```cs namespace System.Linq { public static class Enumerable { public static IEnumerable Repeat(Func selector, int count); public static IEnumerable Repeat(T seed, Func selector, int count); } } ``` ## Usage ```cs // Numbers from 100 to 1 Enumerable.Repeat(100, n => n - 1, 100); // Collect 100 nodes of a linked list (slowly) Enumerable.Repeat(head, n => n.Next, 100); // Record the results of a benchmark 10 times Enumerable.Repeat(_ => RunBenchmark(), 10); ``` 13910 area-System.Linq Run the selector on items during Select.Count chains.

So in other words, we should undo all the `GetCount` optimizations that skip running the selector if `onlyIfCheap` if false. But if it's true, we're probably using it to preallocate a buffer of some sort, & are probably going to use it anyways. So in those scenarios it should be ok to not run the selector. cc @JonHanna 13911 area-Infrastructure FileLoadException when trying to run tests for a different TestTFM "I followed the directions [here](https://github.com/dotnet/corefx/blob/0300e2c42e3ce96240e05daff6f6c5a5e03081a6/Documentation/project-docs/developer-guide.md#running-tests-in-a-different-tfm) and tried running the tests for System.IO on desktop by executing `msbuild /p:TestTFM=net46 /t:RebuildAndTest` in System.IO\tests.

That's the vision at least, in my mind. ### Open Questions Open question is whether the `InitBlock` should be generic to match Span usage, or `Span` should handle forwarding to a `ref byte` version of this. @jkotas @omariom @benaadams @karelz @jamesqo @davidfowl 13917 area-System.Linq Allow for half-lifted conversions in expressions. If a conversion existed from a value type to a nullable type then conversions would not be lifted for the nullable form of the source type. Fix this. Fixes #11992. Also select such lifted operations if the methodless form of the `Convert` factory is used to request automatic selection of convert methods. As well as tests covering this case, include a test ensuring the lifted form is not picked by this change should a direct nullable-to-nullable conversion be available. 13919 area-System.Runtime New Type `System.Runtime.CompilerServices.DependentHandle` There is an internal strut `System.Runtime.CompilerServices.DependentHandle` that is currently only used by `System.Runtime.CompilerServices.ConditionalWeakTable`. The struct allows for a dependency between two objects to be created by a third type without modifying the first two classes, and only using up a pointer's worth of memory in the third type. I have personally find use for such a class, [in my Weak Delegates system for example](https://github.com/SamuelEnglard/weakdelegates/blob/master/WeakDelegates/DependentHandle%602.cs). While in there I had to use slightly convoluted tricks to make it work I believe a more proper implementation included in the BCL would be useful. # API ```csharp namespace System.Runtime.CompilerServices { [ComVisible(false)] public struct DependentHandle : IDisposable where TPrimary : class where TSecondary : class { public bool IsAllocated { get; } [SecurityCritical] public DependentHandle(TPrimary primary, TSecondary secondary); [SecurityCritical] public bool TryGetPrimary(out TPrimary primary); [SecurityCritical] public bool TryGetPrimaryAndSecondary(out TPrimary primary, out TSecondary secondary); [SecurityCritical] public void Dispose(); public override string ToString(); } } ``` It should be noted that my struct is type safe, unlike the internal one. 13920 area-System.Runtime Switch to use CoreLib Path class.

So I suggest make UserDefaultCulture and UserDefaultUICulture properties public. # Rationale and Usage Get current user cultures.

Now if thread culture was changed, we can not get culture for current user.

That puzzled me too, until I found out the version of S.P.CoreLib I was using did not include [this change](https://github.com/dotnet/coreclr/pull/6892); in my tests, a buffer was being allocated every time `List.AddRange` was called. Still, however, the new implementation was faster. I've also added more testing for these changes in the PR. cc @JonHanna @VSadov @stephentoub 13945 area-System.Linq Expressions simplifiy type methods Remove `GetStaticMethods` helper, replacing with call to `GetMethods`, now that the form with `BindingFlag` overloads is available to use.

For example, running the code on something like `"Hello's world"` will result in substring allocations for `quot`, `apos`, and `quot`. Ideally, we would just modify `HtmlEntities.s_lookupTable` to have a key type of a struct `StringSpan`, which would be like `ArraySegment` except for strings.

There are certain Linq methods, such as `Where` and `Take`, where we cannot pinpoint the exact number of elements the iterator will contain, but we can establish an upper bound on how many elements there are. For example, `list.Where(p)` can have at most `list.Count` elements, and `e.Take(5)` can have at most 5 elements. Currently, when we call `ToArray` on any of these iterators, the resizing pattern will be to allocate 4, then 8, then 16, etc. size buffers. This can be wasteful because e.g. if the source enumerable in `Where` contains 100 elements, we allocate space for 128 elements even though those last 28 slots will never be used. This PR adds support to `LargeArrayBuilder` to limit how many elements we allocate, so there is no extra space wasted. It should help drive down allocations in `Where`, `Where.Select`, & `Take` when the maximum count is far from the next power of 2.

"Should have been ""Tests""." 14008 area-Meta UDP Socket using SocketAsyncEventArgs garbage collects nearly every second "I've written a small UDP server with the .Net Core `SocketAsyncEventArgs` implementation, of Sockets. When the server runs, I can see the garbage collection run in the Visual Studio Diagnostics tooling. It runs almost non-stop. Yet when I take Heap snapshots, I don't see hardly any allocations. I fetch my `byte[]` buffers from an `ArrayPool` and I fetch my `SocketAsyncEventArgs` instances from a custom object pool. I have however seen this same behavior when fetching them from another `ArrayPool` instead. In theory, when looking at my code, there should be virtually zero allocations happening, except for what ever the Socket instance is doing. This is a screenshot of the Diagnostics tooling in Visual Studio showing the garbage collections happening. You can see I'm not allocating anything new in the Heap that would warrent that kind of activity. [![enter image description here][1]][1] [1]: https://i.stack.imgur.com/5FwLr.png I pulled the server and object pooling code out and into a reproducible example project. ## ObjectPool Calling `ObjectPool.Rent()` will give you back an instance from the pool. If no instance exists, it will create one using either `System.Reflection.Activator` or a custom `Func` delegate provided, and give it back to you. When you are done, you call `ObjectPool.Return(T);` to place the instance back into the pool for recycling. ```c# public class ObjectPool { private int maxPoolSize; private SpinLock poolLock; private Dictionary> poolCache; private Func factory; public ObjectPool(int poolSize) { this.maxPoolSize = poolSize; this.poolLock = new SpinLock(false); this.poolCache = new Dictionary>(); } public ObjectPool(int poolSize, Func factory) : this(poolSize) { this.factory = factory; } public T Rent() where T : TObject => (T)this.Rent(typeof(T)); public TObject Rent(Type type) { bool lockTaken = false; Stack cachedCollection; this.poolLock.Enter(ref lockTaken); try { if (!this.poolCache.TryGetValue(type, out cachedCollection)) { cachedCollection = new Stack(); this.poolCache.Add(type, cachedCollection); } } finally { if (lockTaken) { this.poolLock.Exit(false); } } if (cachedCollection.Count > 0) { TObject instance = cachedCollection.Pop(); if (instance != null) return instance; } // New instances don't need to be prepared for re-use, so we just return it. if (this.factory == null) { return (TObject)Activator.CreateInstance(type); } else { return this.factory(); } } public void Return(TObject instanceObject) { Stack cachedCollection = null; Type type = typeof(TObject); bool lockTaken = false; this.poolLock.Enter(ref lockTaken); try { if (!this.poolCache.TryGetValue(type, out cachedCollection)) { cachedCollection = new Stack(); this.poolCache.Add(type, cachedCollection); } if (cachedCollection.Count >= this.maxPoolSize) { return; } cachedCollection.Push(instanceObject); } finally { if (lockTaken) { this.poolLock.Exit(false); } } } } ``` ## Server The server can be started by invoking `Server.Start()`. The server uses the new, in Core, `ArrayPool` Type to fetch `byte[]` buffer arrays. It also uses my `ObjectPool` Type to fetch `SocketAsyncEventArgs` instances so it can avoid allocating. Note that in the example I'm not overwriting (cleaning up) the buffer contents as they come and go from the pool, mostly because that code wasn't needed to demonstrate my issue. ```c# public class Server { private ArrayPool socketBufferPool; private ObjectPool socketEventArgsPool; private Socket listeningSocket; private IPEndPoint readEndPoint; private IPEndPoint writeEndPoint; public Server(IPAddress serverIPAddress, int serverPort, int clientPort) { this.readEndPoint = new IPEndPoint(IPAddress.Any, clientPort); this.writeEndPoint = new IPEndPoint(serverIPAddress, serverPort); // Create our object pool, letting it use us as the Factory for creating and setting up new SocketAsyncEventArgs. this.socketEventArgsPool = new ObjectPool(10, this.ConfigureSocketEventArgs); this.socketBufferPool = ArrayPool.Create(256, 100); } public void Start() { this.listeningSocket = new Socket(this.writeEndPoint.AddressFamily, SocketType.Dgram, ProtocolType.Udp); this.listeningSocket.Bind(this.writeEndPoint); SocketAsyncEventArgs readArgs = this.socketEventArgsPool.Rent(); this.listeningSocket.ReceiveFromAsync(readArgs); while (true) { } } private void ReceivedSocketEvent(object sender, SocketAsyncEventArgs e) { // Rent a new Socket event arg right away and start listening for more packets. SocketAsyncEventArgs eventArgs = this.socketEventArgsPool.Rent(); this.listeningSocket.ReceiveFromAsync(eventArgs); this.socketEventArgsPool.Return(e); } private SocketAsyncEventArgs ConfigureSocketEventArgs() { byte[] buffer = this.socketBufferPool.Rent(256); var eventArg = new SocketAsyncEventArgs(); eventArg = new SocketAsyncEventArgs(); eventArg.Completed += new EventHandler(this.ReceivedSocketEvent); eventArg.SetBuffer(buffer, 0, 256); eventArg.RemoteEndPoint = this.readEndPoint; return eventArg; } } ``` ## Program: Server-side This just creates an instance of the Server, provides it with the IP address and ports needed to run, and then starts it. ```c# class Program { static void Main(string[] args) { Console.WriteLine(""Starting server""); var ip = new IPAddress(new byte[] { 10, 0, 1, 6 }); var server = new Server(ip, 11000, 11100); server.Start(); } } ``` ## Program: Client-side This app just opens a Socket on a different port and sends a bunch of datagrams to the server. If I just use a straight `while(true)` I see a massive amount of GC purges on the server side. If I place a `Task.Delay(1).Wait();` within the while loop, I didn't see any during a 3 minute run. Whereas without the `Task.Delay(1).Wait()` I see a GC almost every second. I understand that adding that delay slows down the number of messages sent to the server significantly, but I wanted to share in the event that it helps. ```c# class Program { static byte[] serverAddress = new byte[] { 10, 0, 1, 6 }; static void Main(string[] args) { var clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); // Start listening/sending EndPoint remoteEndPoint = new IPEndPoint(new IPAddress(serverAddress), 11000); while (true) { SendDatagram(clientSocket, remoteEndPoint, ""Hello World!""); //Task.Delay(1).Wait(); } } static void SendDatagram(Socket clientSocket, EndPoint remoteEndPoint, string message) { byte[] msg = Encoding.ASCII.GetBytes(""This is a test""); clientSocket.BeginSendTo( msg, 0, msg.Length, SocketFlags.None, remoteEndPoint, new AsyncCallback(SendCompleted), clientSocket); } private static void SendCompleted(IAsyncResult result) { Socket socket = (Socket)result.AsyncState; socket.EndSendTo(result); } } ``` So the challenge I'm having is figuring out what is causing the GC calls. I see that the Diagnostic tooling says I'm using 17mb of ram, but when I run it outside of the IDE (debug build) it consumes about 3mb. I assume the bulk of the ram consumption is debugger related in the Diagnostic tooling. Could the debugger be causing the GC collections? Is there a means for me to track that outside of the debugger, or determine what objects are being collected?

Continuation of: #14006. Unfortunately, I have a habit of force pushing my commits, so I wasn't able to reopen the old PR. Anyway #12703 was merged this morning so this is no longer blocked; this needs #13628 to apply some optimizations to `Take`, but if this is merged beforehand, I can just update that PR with those changes instead (and vice versa). --- ### Description from original PR There are certain Linq methods, such as `Where` and `Take`, where we cannot pinpoint the exact number of elements the iterator will contain, but we can establish an upper bound on how many elements there are. For example, `list.Where(p)` can have at most `list.Count` elements, and `e.Take(5)` can have at most 5 elements. Currently, when we call `ToArray` on any of these iterators, the resizing pattern will be to allocate 4, then 8, then 16, etc. size buffers. This can be wasteful because e.g. if the source enumerable in `Where` contains 100 elements, we allocate space for 128 elements even though those last 28 slots will never be used. This PR adds support to `LargeArrayBuilder` to limit how many elements we allocate, so there is no extra space wasted. It should help drive down allocations in `Where`, `Where.Select`, & `Take` when the maximum count is far from the next power of 2. --- [Performance test][1] / [analysis](https://gist.github.com/jamesqo/0ca128f95f59cd434f7ec544ce09377e) There are major reductions in GCs (about 25%) when the length of `_source` is just above a power of 2, and the predicate returns true for every item. cc @JonHanna @VSadov @stephentoub [1]: https://github.com/jamesqo/Dotnet/blob/fd26359a7b7d53b0598887ab58f54d591f3b7b40/Program.cs 14021 area-System.Reflection Proposal: Add new GetValue method to System.Reflection "This new method would accept an ""object"" to which a Value could be copied instead of being unnecessarily boxed. Example of use would look like this: ``` static object boxedFloat = null; .... boxedFloat = fieldInfo.GetValue( myObject, boxedFloat ); ``` Boxing of the value would occur only once. This would eliminate unnecessarily memory allocations in situations when GetValue is called many times. When method is used on a class types, copying would not occur and stored object would be returned instead. One of the uses of GetValue method is User Interface based on MVVM (Model View Viewmodel) where values used to control an UI are pulled directly from the data. In realtime applications (like games) this boxing makes hundreds if not thousands of unnecessary memory allocations every second. Another use of GetValue is serialization, and having ability to serialize hundreds of values without the need of boxing/unboxing, would greatly improve memory usage and performace. There was also an idea https://github.com/dotnet/coreclr/issues/8277 that this new GetValue method would take a form of generic method, but I think this would limit the use as one of the advantages of working with System.Object is this abstraction that makes some parts of the code simpler. So, ideally this new method should remove the unnecessary boxing while keeping convenience of System.Object. Additionally please bear in mind this should work with both FieldInfo and PropertyInfo, as well as give option to get values from nested Value as in following example: ``` struct Vector3 { float x,y,z; } struct Transform { Vector3 position { get; set } } transform = positionProperty.GetValue( transformObject, transform ); boxedX = xField.GetValue( transform, boxedX ); DisplayValue( boxedX ); ``` (note intermixing fields with property)" 14022 area-System.Linq Wrong parameter name if passing generic type to Expression.New "`Expression.New(typeof(List<>))` throws an `ArgumentException` reporting the parameter name as ""constructor"" though the name of the parameter in question is ""type""." 14023 area-System.Linq Reuse _state in some iterators.

This proposal aims to expose this functionality to improve interop with external applications that manage socket connections. # Rationale and Usage Currently, a socket must be both created and managed by the user application. While this is desired behaviour in most cases, there is no mechanism to take an existing socket handle/file descriptor and make use of it within the user application. If one wanted to use a socket that was created by an external application, the only option (outside of reflection hacks) is to reimplement the calls to the underlying platform sockets with P/Invoke - largely removing the benefits that the managed socket classes provide. More specifically, this improves interop with existing applications that manage socket connections, such as systemd and the socket activation feature. In this scenario, systemd creates an unmanaged socket to listen for connections. Once a connection is established, a .NET application is launched and a file descriptor that references the unmanaged socked is passed to it through environment variables. Without the ability to create a managed socket from a file descriptor, the connection will need to be reset and then reestablished using the managed APIs - rather than cleanly being passed through and maintained. # Proposed API ```c# namespace System.Net.Sockets { // Previously implemented socket class public partial class Socket : System.IDisposable { // Existing constructors public Socket(System.Net.Sockets.AddressFamily addressFamily, System.Net.Sockets.SocketType socketType, System.Net.Sockets.ProtocolType protocolType) { } public Socket(System.Net.Sockets.SocketInformation socketInformation) { } public Socket(System.Net.Sockets.SocketType socketType, System.Net.Sockets.ProtocolType protocolType) { } private Socket(SafeCloseSocket fd) { } // Additional existing members omitted // Proposed member public Socket(IntPtr fileDescriptor, AddressFamily addressFamily, SocketType socketType, ProtocolType protocolType) { } } } ``` # Details * Adding this rather than exposing the existing Socket(SafeCloseSocket fd) constructor will keep the rest of the socket PAL internal, as there's currently public no way (as far as I can tell) to create an instance of SafeCloseSocket from a IntPtr. * This will align with user expectations coming from other languages, such as Python, which has a similar method to create a socket from a file descriptor (see [socket.fromfd(fd, family, type[, proto])](https://docs.python.org/2/library/socket.html#socket.fromfd)). * Platforms that don't support wrapping unmanaged sockets (or that don't expose them, such as UWP?) will throw PlatformNotSupportedException. 14044 area-System.Linq Fixing regression in CallFactoryTests Merging https://github.com/dotnet/corefx/commit/c3938a0589f3a8d51b6d8391f73ec42bf8cf4d61 caused a regression because other `MethodCallExpression` tests were added in the meantime.

This API is intended to be used primarily for optimizations: - Generic List calls Array.Clear on its underlying array in the implementation of Clear, RemoveAll, RemoveRange methods today. It has to do so because the generic argument can contain references which must be freed for GC. It can be skipped using this method when not required. - Algorithms for memory manipulations can have optimized paths for memory blocks without GC references. This method can be used to determine whether the optimized path is safe to use. `Span` is example of such memory manipulation algorithms. It going to use this API internally in its implementation. This API addition was tracked by CoreCLR issue. https://github.com/dotnet/coreclr/issues/1135 has a lot of discussion about the right name for this API.

However, I've noticed some annoying behaviour, as follows: 1) If I drag and drop a file onto my phone using Windows Explorer, the original file's DateModified is written to the phone. If I copy the same file using WinRT's StorageFile.CopyAsync method, the DateModified is not copied over and it seems to use the current time as the DateModified. I've tried updating the ""System.DateModified"" property manually after the file is copied and I get an error saying the property is read only. 2) Using Windows Explorer, I can create folders inside the phone's Music folder (which is marked as Read Only). However, using StorageFolder.CreateFolderAsync I get an error saying: ``` System.Runtime.InteropServices.COMException: Unspecified error Cannot create items within this StorageFolder. This could be encountered if the folder was obtained by creating a query using grouping options. ``` Interestingly, I can copy files to the Music folder using the API (using the StorageFile.CopyAsync method), I just can't create folders.

This can happen even if another overload is correctly specified, so can throw on code that should not throw at all. 3.

Note that `List` does a cast to `uint` as part of the bounds check to cover this case. - [ ] The indexer doesn't check for `index` being larger than or equal to 0, resulting in accessing the underlying array with a negative index, causing `IndexOutOfRangeException`. Note that `List` does a cast to `uint` as part of the bounds check to cover this case. - [ ] `Reverse` lacks good bounds checks which can result in reversing a range of elements in the underlying array including the trailing empty slots, which then become visible. - [ ] Exception behavior is not documented. 14060 area-Meta Enable CS2229 and CA2237 This change enables FxCop serialization rules requiring serialization constructors on ISerializable types and [Serializable] on ISerializable types. 14061 area-System.Linq Throwing more derived exception types in ReadOnlyCollectionBuilder Eliminating the use of `ContractUtils.Requires` which results in throwing `ArgumentException` where more derived types are more applicable.

When checking if a sequence has X elements or more calling `Count()` is not just expensive but wasteful. ## Proposal ```diff namespace System.Linq { public static class Enumerable { + /// + /// Returns if a sequence has at least a certain amount of elements. + /// + /// The type of elements of . + /// An to check the length of. + /// The minimum amount of items that should have. + /// if has at least elements. otherwise. + /// is . + /// must be zero or greater. + public static bool HasAtLeast(this IEnumerable source, int atLeast); } } ```" 14079 area-System.Linq Cleanup of code in DynamicExpression Some trivial cleanup to make the code more concise using C# 6.0 features, just like we did for other types prior to the merge of `System.Dynamic.Runtime`.

However, the recent discussion #14021 revealed that it is a good building block for new high-performance reflection APIs that avoid boxing and address other reflection limitations. We should consider bringing it back. The steps are: 1. Bring TypedReference back (to .NET Standard 2.0?) 2. Add methods to TypedReference that make it useful (e.g. use generic methods as a first class replacement for the undocumented C# `__refvalue` and similar keywords) 3. Add high-performance reflection APIs that avoid boxing (see #14021 for discussion) This issue is tracking the first step. 14089 area-Infrastructure rhel rid should not include a minor. rhel-7.2-x64 should be rhel-7-x64 Just like Debian (https://github.com/dotnet/corefx/issues/6170), minor releases are point releases. The minor should not be part of the rid. 14090 area-System.Collections Port thread pool's work stealing implementation to ConcurrentBag Every Add to a ConcurrentBag allocates a new Node to store into the thread local list, which is a linked list. In contrast, ThreadPool also uses a work-stealing queue, but one that's array-based, avoiding needing an extra allocation per item. We should investigate using thread pool's work-stealing implementation in ConcurrentBag, to avoid that allocation. And if for some reason it's not possible exactly as is (e.g. the thread pool implementation assumes that the stored items are references and thus can be read/written atomically), there are potentially adaptations that would allow it to work (e.g. ConcurrentBag could wrap value types in pooled objects). 14091 area-System.Linq Using InterpretedFrame.Dup helper For some reason, we never used the `Dup` method here. 14092 area-System.Linq Removing unnecessary code analysis suppressions Some remnants that are no longer relevant. 14093 area-Infrastructure Enable Dumpling service to collect dumps from hangs/crashes in CI/full builds 14095 area-Meta Enable and fix/baseline worthwhile FXCop rules on CoreFX codebase dotnet/coreclr#7880 covers this for mscorlib. @alexperovich will drive this.

While looking at this, I noticed a few more things: * `ArrayAccess` is called with the `params Expression[]` overload, causing a copy to be created. Now calling the `IEnumerable` overload, passing it a `TrueReadOnlyCollection`. * The `Invoke(rule, ...)` expression is used multiple times, leading to multiple allocations of the node and its children collection. Reuse this part of the tree. * The `Assign(rule, ArrayAccess(...))` expression is used multiple times, with the same effects as described above. Reuse this part of the tree. Note that this method always calls `Compile` on the resulting expression, so there are no worries about reference equal subexpressions; the user can never observe the tree that was created. 14101 area-System.Net Ensure that all System.Net tests are running against NetFX Ensure that all System.Net Functional tests run against both Core and NetFX. /cc @karelz @davidsh 14103 area-System.Net [WinHttp] WebSocket.ReceiveAsync throws internal exception type WinHttpException "When the remote side of the conversation closes the connection abruptly while a WinHttpWebSocket is receiving the Exception thrown is a WinHttpException.

Is it correct change ? 14119 area-System.Linq Consider adding more LINQ operators from Ix.NET https://github.com/dotnet/corefx/issues/13842 introduces `TakeLast` and `SkipLast` which existed in [Ix.NET](https://github.com/Reactive-Extensions/Rx.NET/tree/master/Ix.NET/Source/System.Interactive) (`System.Interactive`, which is part of the Reactive Extensions project) for a long time. This may be a good time to review other operators we got in Ix.NET and see whether they're worth adding to .NET proper. I'm pasting a short selection (using the Ix names) below: ### Min and Max with IComparer No overloads of these operators exist with an `IComparer`. The existing overload uses `Comparer.Default` to get the comparer. It seems an omission that we don't provide an option to pass in a custom comparer. ```csharp public static TSource Min(this IEnumerable source, IComparer comparer); public static TSource Max(this IEnumerable source, IComparer comparer); ``` ### MinBy and MaxBy to select element(s) with lowest/highest key value Similar to `MinimalBy` and `MaximalBy` in Mathematica. The current overloads with a `Func` are merely shortcuts for `xs.Select(f).Max()` rather than providing a means to get the list of values that have the lowest projected value (e.g. the list of people with the lowest value for `Age`). ```csharp public static IList MinBy(this IEnumerable source, Func keySelector); public static IList MinBy(this IEnumerable source, Func keySelector, IComparer comparer); public static IList MaxBy(this IEnumerable source, Func keySelector); public static IList MaxBy(this IEnumerable source, Func keySelector, IComparer comparer); ``` ### Concat (or Flatten or Unwrap) Just like `Task>` can be unwrapped into `Task` or `AggregateException` can be flattened. Obviously, this is just a macro for `xss.SelectMany(xs => xs)`, but possibly more descriptive and having better performance. ```csharp public static IEnumerable Concat(this IEnumerable> sources); public static IEnumerable Concat(params IEnumerable[] sources); ``` ### StartWith (Prepend with multiple values) I noticed we've added `Prepend`. Ix provides `StartWith` which is basically the same but takes a `params` array with elements to prepend. (Note it comes from the dual of `StartWith` on `IObservable` where we can start an event sequence with one or more initial values provided from an array.) It could be done quite easily today using `new[] { ... }.Concat(xs)` but may be deemed a natural extension to `Prepend`. ```csharp public static IEnumerable StartWith(this IEnumerable source, params TSource[] values); ``` ### Scan (aggregate yielding intermediate results) Totally analogous signatures to `Aggregate` but yields every intermediate computed result. As usual, it comes from the duality with Rx where we deal with streams of events (that may never terminate). This said, it has value on a lazy enumerable sequence, e.g. when processing large logs and providing all intermediate aggregation values as the analysis is going on. `Aggregate` is pretty much `Scan` followed by `Last`, only optimized. ```csharp public static IEnumerable Scan(this IEnumerable source, TAccumulate seed, Func accumulator); public static IEnumerable Scan(this IEnumerable source, Func accumulator); ``` There are a bunch more that are likely a bit more esoteric and of lesser value, but nonetheless worth having a look at. One family of them deals with sharing side-effects of enumeration in a less aggressive way than the traditional `ToArray` to `ToList` approach; see things like `Share`, `Memoize`, and `Publish`. It's been a while since I've worked on / looked at this code, so some design decisions may have eroded from my memory, but I'll do my best recollecting these if questions come up. 14122 area-System.Linq Eliminating unnecessary closures in DynamicObject In cases a `Try*` method is not overridden, there's no need to allocate a closure that's only required in case there's an override.

This PR removes all of those allocations: - The first allocation (per-Add Node) is addressed by changing from a linked-list-based scheme to an array-based scheme; the logic for the latter is taken from ThreadPool (https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Threading/ThreadPool.cs#L133), which uses an array-based work-stealing implementation for the thread-local queues in the pool. - The second allocation is avoided by caching a per-thread list in TLS, so that any steal operation can just use that list from TLS. These changes effectively eliminate all per-operation allocations in ConcurrentBag. In addition to the GC impact, these changes have a beneficial impact on throughput, due to better memory locality with the array vs with a linked list, less code needed for pushes/pops, etc. In a test that adds 10M items from a single thread: Before (elapsed time and gen0 GCs): ``` 00:00:02.2688554 67 00:00:02.6047316 66 00:00:02.1908836 65 00:00:02.7931760 68 ``` After: ``` 00:00:00.8325350 0 00:00:00.8284697 0 00:00:00.8600504 0 00:00:00.8094874 0 ``` In a test that has 4 threads each adding 2 items then taking 2 items (no steals), repeatedly, 5M times: Before: ``` 00:00:02.9780786 767 00:00:02.7218693 767 00:00:02.7535170 767 00:00:02.7547491 767 ``` After: ``` 00:00:01.5986701 0 00:00:01.3661083 0 00:00:01.4061545 0 00:00:01.3687102 0 ``` In a test that has one thread adding 10M items and another thread taking until all 10M are stolen (effectively the worst case for ConcurrentBag): Before: ``` 00:00:03.1549239 332 00:00:03.2892691 340 00:00:03.1984057 349 00:00:03.3697942 346 ``` After: ``` 00:00:02.5558069 0 00:00:01.8004534 0 00:00:02.5968542 0 00:00:02.1146025 0 ``` Prior to this change, devs were often hesitant to use ConcurrentBag as an object pool for small objects, as each added object involved its own small Node allocation.

This results in the following behavior: ``` C# var letter = """"; var q = from db.Beattles.Where(p => p.Name.StartsWith(letter)); // variable letter gets captured letter = ""P""; var beattle1 = q.First(); // Returns Paul letter = ""J""; var beattle2 = q.First(); // Returns John ``` A few operators like `Skip`, `Take`, `ElementAt`, `DefaultIfEmpty`, `Aggregate` and `Contains` (#13842 proposes a couple of additions) however accept arguments of simple types. Unless these operators appear nested inside other expressions, variables won't be captured but values. This pattern results in the following behavior: ``` C# var position = 1; var q = from db.Orders.Skip(position - 1); // a value of 0 gets captured position = 10; var tenth = q.First(); // returns the first Order position = 20; var twentieth = q.First(); // still returns the first Order ``` Each of these behaviors can be seen as correct, but IMO the fact that they are different can be subtle and confusing unless you know about the closures. A possible way to address this is to add overloads that capture, e.g. for `Enumerable.Skip(int)` the signature of the new overload would be: ``` C# public static IEnumerable Skip( this IEnumerable source, Func countAccessor) ``` Usage would be as follows: ``` C# var position = 1; var q = from db.Orders.Skip(() => position - 1); position = 10; var tenth = q.First(); position = 20; var twentieth = q.First(); ``` Another side effect manifests in specific translating LINQ providers such as the one contained in EF6 in which whether a value or a variable is captured influences whether a literal or a parameter is generated in the resulting SQL query. This simple rule enables some control over the SQL that gests generated but in the past it was the reason that repeated execution of queries that contained paging (i.e. `Skip` and `Take`) operations would pollute the database query cache (see http://stackoverflow.com/questions/9201403/force-entity-framework-to-use-sql-parameterization-for-better-sql-proc-cache-reu for more details). For this reason EF6 already defines overloads of `Skip()` and `Take()` that accept `Expression>` arguments.

Today if someone want to achieve the same result as the proposed APIs will write a code like ```C# var now = DateTime.Now; var zone = TimeZoneInfo.FindSystemTimeZoneById(""Turkey Standard Time""); var localTime = TimeZoneInfo.ConvertTime(now, zone); Console.WriteLine($""{localTime.ToLongDateString()}""); ``` and will need to call the time zone conversion API TimeZoneInfo.ConvertTime every time before formatting the date/time. Also today there is no easy way to format the DateTime with a target time zone using a formatting pattern like ""o"" which include the time zone information. for example doing: ```C# var now = DateTime.Now; var zone = TimeZoneInfo.FindSystemTimeZoneById(""Turkey Standard Time""); var localTime = TimeZoneInfo.ConvertTime(now, zone); Console.WriteLine($""{localTime.ToString(""o"")}""); ``` will produce something like ``` 2017-01-17T23:37:21.1371643 ``` which either will show the formatted string without the time zone info or if the time zone info is there will be matching the local time zone or UTC time zone but cannot have the target time zone information. The desired formatted string from the example should be something like ``` 2017-01-17T23:37:21.1371643+03:00 ``` where +03:00 reflect Turkey time zone offset from UTC. the way the proposed APIs work will manually check the Kind of the DateTime, if it is Local/Unspecified then it will convert the DateTime from local time zone to target time zone. if the Kind is UTC, will convert it from UTC to target time zone. If the output format is the one which include the time zone info (e.g. 'o' pattern), the resulted formatted string should reflect the target time zone. ## Sample Code ```C# var now = DateTime.Now; var zone = TimeZoneInfo.FindSystemTimeZoneById(""Turkey Standard Time""); Console.WriteLine($""{now.ToLongDateString(zone)}""); ``` " 14161 area-Infrastructure Add RID for Linux/ARM32 (ubuntu) Add RID for Linux/ARM32 - ubuntu*-arm related PR: https://github.com/dotnet/coreclr/pull/8421 14162 area-Meta Profiling tools on linux Is there any tools to take memory dump and see objects of running .NET Core app on linux?

This change brings in code to build only those libraries contributing to a specific vertical. The code was originally written as a proof-of-concept against corefx/master. Not being able to play in dev/eng means that the code base quickly diverged and now there is quite a bit of cleanup work to bring these changes back in line with the direction of dev/eng. Work to be done (I'll capture all of this in a separate issue): - Refactor to consume Eric's configurations props file - Make the vertical build a first-class citizen, in its current implementation, you only perform a vertical build if you include `/p:VerticalGroup=Windows_NT-netcoreapp1.1-Debug`. Making it a first class build means we can get rid of quite a bit of code from buildvertical.targets and eliminate buildvertical.traversal.targets - Default target group is no longer a concept, update Configurations to reflect that and remove default target group code. - Some libraries which were previously building, are not building cleanly in dev/eng, I've omitted these from the build by adding an 'omit.txt' file in the library folder. - Names of properties / targets / etc will probably need to change because concepts have changed - Binary output needs to be updated to conform with Wes' documented spec - https://github.com/dotnet/corefx/blob/63205dc4918e0520c3c512f322d00c3206c5a9ff/Documentation/coding-guidelines/project-guidelines.md I don't want to slow down anyone's work which requires this build output, so I'm ok with submitting this code as-is if it is needed and cleaning it up with additional checkins as we evolve the code, i'm also ok with holding off on checking this in. I'd prefer not to check-in as-is if nobody is clamoring for the work. Now that I am working in dev/eng, I am feeling far less angst about being removed from the rest of the vertical build changes. /cc @ellismg @weshaggard @ericstj @mellinoe @markwilkie 14173 area-System.Linq Optimize new ToHashSet api. #13726 added `Enumerable.ToHashSet`, which is currently equivalent to writing `new HashSet(items)`.

The only difference is that the latter version is faster because it is not an extra call. Previously, the only compelling reason to use the former was that if `item` was an enum, then calling `GetHashCode` directly would box while `EqualityComparer` wouldn't (see [here](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Collections/Generic/EqualityComparer.cs#L63)). However, [this change](https://github.com/dotnet/coreclr/pull/7895) in coreclr and [this one](https://github.com/dotnet/corert/pull/2117) in corert eliminate boxing for enums, so there is no longer a reason to use `EqualityComparer` in ValueTuple.

This is analoguous to the same method approved for arrays in https://github.com/dotnet/corefx/issues/6695 and added in https://github.com/dotnet/coreclr/pull/8137, https://github.com/dotnet/corert/pull/2259 but still lacking optimization https://github.com/dotnet/coreclr/issues/8290, perhaps `Array.Fill` could forward to `Span.Fill` in the future... ### Rationale and Usage Provide a safe yet fast way of filling of any type of contiguous memory; managed or unmanaged. ```csharp var span = new Span(array, 3, 10); span.Fill(42); ``` The argumentation for adding this is similar to `Array.Fill`, but here with a wider use case, since this can be used with both managed and unmanaged memory: * To increase the efficiency of code doing this and prevent people from reinventing the wheel. * Allow performance optimizations depending on memory type and contents. ### Proposed API Add a single method `Fill(T value)` to the existing `Span` API: ```csharp public class Span { public void Fill(T value); } ``` ### Open Questions Open question is whether this should be added as a member method or an extension method. I would argue for a member method, since this will depend on internal representation, and would perhaps allow for the JIT intrinsic version to do optimizations that a generic extension method can't. If that is a valid argument? @karelz @jkotas @omariom @benaadams @jamesqo 14190 area-System.Collections Improve ConcurrentBag.ToArray/GetEnumerator/CopyTo/IsEmpty performance "ToArray and CopyTo take a moment-in-time snapshot of the bag by freezing it, copying the contents to an array, and unfreezing. However, that copy is done via an intermediate List, which results in potentially many unnecessary allocations and copies. Changes: - This commit fixes that by first counting how many items there are in the bag and either presizing the array (in the case of ToArray) or comparing the length (in the case of CopyTo) and then copying directly into the target, eliminating the extra allocations. - There is still an intermediate allocation for the non-generic ICollection.CopyTo(Array, int) method, but to avoid that in common cases, it now special-cases T[] and uses the more efficient CopyTo(T[], int) implementation for that common case. - GetEnumerator was similarly implemented to first copy to a list and then get its enumerator. It now uses the ToArray implementation instead. This also means that for empty bags, we end up returning Array.Empty, which means the returned enumerator from it is also a singleton. - Additional fast paths were added to IsEmpty. It also had a fast path to check to see if the bag was void of any queues, in which case we know the bag is empty. I've also added checks for the local queue. If the local queue isn't empty, then we know the bag isn't empty and we can avoid freezing/unfreezing. If the local queue is empty and it's the only one in the bag, then we can similarly avoid freezing/unfreezing, as we know the whole bag is empty. - Added some additional tests. Note: There are two small technically breaking changes here: - ((ICollection)bag).CopyTo when passed a T[] with a bad index would previously throw an ArgumentOutOfRangeException with the name ""dstIndex"". That's because that's what Array's CopyTo implementation uses as the parameter name, even though this makes very little sense: the name of that property in both ICollection.CopyTo and in ConcurrentBag.CopyTo is ""index"". As a side-effect of the CopyTo(Array, int) optimization that checks for T[] and forwards it to CopyTo(T[], int), we end up using ""index"" instead of ""dstIndex"" for the argument name in the exception. - GetEnumerator used to return the result of calling GetEnumerator on the generated ```List```; now it calls GetEnumerator on the generated ```T[]```. ```List``` and ```T[]``` have different implemented behaviors for the undefined situation of calling Current on an enumerator after MoveNext has returned false: for ```List``` it returns default(T) and for array it throws an exception. By switching from using a ```List``` to a ```T[]```, this behavior has also switched. If we wanted to deal with this, we could by writing a custom enumerator implementation, but it seemed unnecessary. For this perf test that fills a bag with N queues and M items per queue and then calls ToArray on it 10M times: ```C# using System; using System.Diagnostics; using System.Threading; using System.Threading.Tasks; using System.Collections.Concurrent; using System.Linq; class Test { public static void Main() { var sw = new Stopwatch(); var counts = new[] { 1, 4, 16, 64 }; foreach (int threads in counts) { foreach (int itemsPerQueue in counts) { var bag = new ConcurrentBag(); var b = new Barrier(threads); Task.WaitAll(Enumerable.Range(0, threads).Select(_ => Task.Factory.StartNew(() => { b.SignalAndWait(); for (int perQueue = 0; perQueue < itemsPerQueue; perQueue++) bag.Add(perQueue); }, CancellationToken.None, TaskCreationOptions.LongRunning, TaskScheduler.Default)).ToArray()); int gen0 = GC.CollectionCount(0); sw.Restart(); for (int i = 0; i < 10000000; i++) bag.ToArray(); sw.Stop(); gen0 = GC.CollectionCount(0) - gen0; Console.WriteLine($""Threads: {threads,3} PerThread: {itemsPerQueue,3}.

I get the error below when my app is running on Debian 8 as a non-privileged user created by `adduser --system --no-create-home`. Apparently in order to verify the SMTP server's certificate, FX code attempts to create a directory under `/root/`, which is where $HOME points to in my scenario. While this formally makes sense, it seems counter-intuitive that code run as a non-privileged user without a home as above would a) end up accessing `/root/` in this scenario, and b) that it would not fall back to just not caching the cert if it hits UnauthorizedAccessException (or any IO exception?). ``` System.UnauthorizedAccessException: Access to the path '/root/.dotnet/corefx/cryptography/crls' is denied. ---> System.IO.IOException: Permission denied --- End of inner exception stack trace --- at System.IO.UnixFileSystem.CreateDirectory(String fullPath) at System.IO.Directory.CreateDirectory(String path) at Internal.Cryptography.Pal.CrlCache.GetCachedCrlPath(X509Certificate2 cert, Boolean mkDir) at Internal.Cryptography.Pal.CrlCache.DownloadAndAddCrl(X509Certificate2 cert, SafeX509StoreHandle store, TimeSpan& remainingDownloadTime) at Internal.Cryptography.Pal.CrlCache.AddCrlForCertificate(X509Certificate2 cert, SafeX509StoreHandle store, X509RevocationMode revocationMode, DateTime verificationTime, TimeSpan& remainingDownloadTime) at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.BuildChain(X509Certificate2 leaf, HashSet`1 candidates, HashSet`1 downloaded, HashSet`1 systemTrusted, OidCollection applicationPolicy, OidCollection certificatePolicy, X509RevocationMode revocationMode, X509RevocationFlag revocationFlag, DateTime verificationTime, TimeSpan& remainingDownloadTime) at Internal.Cryptography.Pal.ChainPal.BuildChain(Boolean useMachineContext, ICertificatePal cert, X509Certificate2Collection extraStore, OidCollection applicationPolicy, OidCollection certificatePolicy, X509RevocationMode revocationMode, X509RevocationFlag revocationFlag, DateTime verificationTime, TimeSpan timeout) at System.Security.Cryptography.X509Certificates.X509Chain.Build(X509Certificate2 certificate) at System.Net.Security.CertificateValidation.BuildChainAndVerifyProperties(X509Chain chain, X509Certificate2 remoteCertificate, Boolean checkCertName, String hostName) at System.Net.Security.SecureChannel.VerifyRemoteCertificate(RemoteCertValidationCallback remoteCertValidationCallback) at System.Net.Security.SslState.CompleteHandshake() at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ReadFrameCallback(AsyncProtocolRequest asyncRequest) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Net.Security.SslState.InternalEndProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.SslState.EndProcessAuthentication(IAsyncResult result) at System.Net.Security.SslStream.EndAuthenticateAsClient(IAsyncResult asyncResult) at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at MailKit.Net.Smtp.SmtpClient.Connect(String host, Int32 port, SecureSocketOptions options, CancellationToken cancellationToken) at MailKit.MailService.Connect(String host, Int32 port, Boolean useSsl, CancellationToken cancellationToken) ``` 14201 area-Infrastructure Report agent disk usage 14202 area-Infrastructure Auto-generate Microsoft.NETCore.Platforms\runtime.json Ref: https://github.com/dotnet/corefx/pull/14142#discussion_r90922312 /cc @ericstj 14203 area-Infrastructure Referencing Microsoft.NETCore.App 1.2.0-* results in type ambiguity "I was attempting to upgrade AspNetCore packages to 1.2.0-* M.NETCore.App \ 4.4.0-* CoreFx packages.

With no AppDomains in .NET Core, my understanding is that System.Reflection.Metadata is recommended for this type of scenario. I imagine that System.Reflection.Metadata was implemented with structs and handles to improve performance for low level operations. While that decision makes sense, it means the API is a lot more difficult to use compared to normal reflection. Is there a reason an easier to use API wasn't implemented as a wrapper around the structs? I implemented one myself after looking all over for an alternative and I'm hoping I didn't spend the last two days reinventing the wheel. https://github.com/Byrne-Labs/Metadata-DOM https://nuget.org/packages/ByrneLabs.Commons.MetadataDom 14220 area-System.Linq Proposal: Queryable.Append, Queryable.Prepend **Important note:** There is a chance this API could be breaking. People who are already calling `Append` on some Queryable will be calling into the Enumerable version, which returns an `IEnumerable`. Meanwhile, the proposed overloads return an `IQueryable`. However, these APIs have been out for [less than a year](https://github.com/dotnet/corefx/pull/5947) and people seem to agree that keeping symmetry with Enumerable is more valuable. --- Per discussion at https://github.com/dotnet/corefx/pull/14186#discussion_r90985817 We should add `Queryable.Append` and `Prepend` extension methods since they already exist on `Enumerable`. ## Proposal ```c# namespace System.Linq { public static class Queryable { public static IQueryable Append(this IQueryable source, TSource element); public static IQueryable Prepend(this IQueryable source, TSource element); } } ``` cc @JonHanna @bartdesmet 14221 area-System.Collections Refactor ConcurrentBag/Queue/Stack tests - Added a base IProducerConsumerCollectionTests tests class. - Moved common tests from ConcurrentBag/Queue/StackTests down to IProducerConsumerCollectionTests, with each class' test class deriving from the shared class, such that all of these tests now operate against each of ConcurrentBag/Queue/Stack. - Added a few additional tests. cc: @ianhays, @alexperovich 14222 area-Infrastructure Remove build.clean=All from build pipeline settings @chcosta @weshaggard @karajas Work around this crash from VSO Build Agents: 2016-12-06T00:46:19.0959402Z 'build.clean=All' 2016-12-06T00:46:19.0959402Z Checking if build directory exists: D:\A\_work\36 2016-12-06T00:46:19.0959402Z Deleting build directory. 2016-12-06T00:46:31.2505525Z ##[error]System.ComponentModel.Win32Exception (0x80004005): The directory is not empty 2016-12-06T00:46:31.2505525Z ##[error] at Microsoft.TeamFoundation.Common.FileSpec.DeleteDirectoryLongPath(String path, Boolean recursive, Boolean followJunctionPoints) 2016-12-06T00:46:31.2661693Z ##[error] at Microsoft.TeamFoundation.Common.FileSpec.DeleteDirectoryLongPath(String path, Boolean recursive, Boolean followJunctionPoints) 2016-12-06T00:46:31.2661693Z ##[error] at Microsoft.TeamFoundation.Common.FileSpec.DeleteDirectoryLongPath(String path, Boolean recursive, Boolean followJunctionPoints) 14224 area-Serialization Call FormatterServices.GetUninitializedObject Directly.

The issue was premature finalization of the original context which was copied for the failing test. The documentation on CertDuplicateCertificateContext states it just increments the ref count and expects a call later to CertFreeCertificateContext to decrement the ref count. However, it appears from testing that if the original context handle has CertFreeCertificateContext called on it then the other (copied) contexts are affected which causes the issue. Thus for the copy of the cert, avoid calling CertDuplicateCertificateContext as the original cert can then be collected\finalized causing the context to become invalidated (or at least prevents a private key from being extracted). cc @bartonjs 14237 area-System.Net TCP_KEEPALIVE, TCP_KEEPINTVL, and TCP_KEEPCNT Socket Options I am trying to set per-socket keepalive TCP timeouts on Linux and MacOS.

Additionally, every handle has a flag on it specifying if it is inheritable or not. CoreFx has the `bInheritHandles` argument hard coded to `true`. While this feature can be useful, it can cause untold number of problems. This of the situation where you have a file handle, and you've acquired that file handle with `FileShare.None` set. While the handle is opened, you start a child process. That child gets a copy of that handle, now they cannot use it because you've selected no sharing, but they have a copy of it. Since closing of file handles is a reference counting game, you're now unable to close the file. Sure, you can close your local handle, but you'll be unable to re-open it until the child process' handle is closed as well. If the child spawns a child, the grand-child process will also keep a copy of the handle and could never get your file back. This becomes worse in the case of redirected pipes. Imagine this setup: 1. Thread A starts creating a new process with redirected output 2. Thread B starts creating a new process designed as a long running service (think redis or something) 3. Thread A creates the necessary handles to redirect output. 4. Thread B calls Kernel32.dll!CreateProcess to create the process, the new process inherits the handles Thread A created for its child (but it doesn't know that and it cannot use them). 5. Thread A calls Kernel32dll!CreateProcess. 6. Thread A attempts to read standard output until it closes. 7. Thread A child process exits, and closes the handles it was given __BUT__ the pipes do not close because Thread B child process has a handle on them (and closing is a reference counting game). Effectively, Thread A is deadlocked attempting to read from the stand output pipe of its child process (even though said process has exit already) until Thread B child process exits (and closes its handles). This is a disaster. Handle inheritance should be take seriously, and it appears the CoreFx library isn't doing so. Ideally, the `bInheritHandles` parameter would be null unless `STARTF_USESTDHANDLES` is specified. When `STARTF_USESTDHANDLES`, then the advice of Raymon Chen should be followed: ""[The case of the redirected standard handles that won’t close even though the child process has exited](https://blogs.msdn.microsoft.com/oldnewthing/20131018-00/?p=2893)"". There is an attempt to correct this bad behavior via a `Monitor` lock placed around the calls to `CreateProcess` calls. This is fine so long as all code in a process is running though CoreFx, but in any reasonable sized project that cannot be assumed.

I'd expect this to be the usual properties of a [total order](https://en.wikipedia.org/wiki/Total_order). 14247 area-System.Net Exposing missing APIs in System.Net.HttpListener contract to sync wit… fixes #13901 cc @karelz @danmosemsft @CIPop Adding tests are tracked in issue #13618 14253 area-Serialization Add Test Project for Running XmlSerializer Tests in ReflectionOnly Mode We added test project running DataContractSerializer tests in ReflectionOnly mode, see https://github.com/dotnet/corefx/issues/10967. We should make the same change for XmlSerializer. 14254 area-System.Collections Rewrite ConcurrentQueue for better performance This commit rewrites ConcurrentQueue to provide better throughput and a much better allocation profile. As with the previous implementation, it's structured as a linked list of segments. Unlike the previous implementation, these segments are now ring buffers, allowing them to be reused as long as they're not full; if an enqueue does make a segment full, then a new segment is created for subsequent enqueues. Also unlike the previous implementation, segments are dynamic in size, so newly allocated segments follow a doubling scheme similar to that employed by other generic collections. The synchronization mechanism used is also lower-overhead than before, with a typical operation incurring just one CAS operation to either enqueue or dequeue. In a test that just enqueues 20M items serially: ``` Old - Time: 0.461s GC: 27 New - Time: 0.237s GC: 0 ``` In a test that enqueues and dequeues 20M items serially (adding 1, taking 1, adding 1, taking 1, etc.): ``` Old - Time: 0.631s GC: 32 New - Time: 0.374s GC: 0 ``` In a test that has 4 threads (quad core) each enqueueing 5M items in parallel: ``` Old - Time: 0.997s GC: 27 New - Time: 0.244s GC: 0 ``` In a test that has 2 threads each enqueueing 5M items in parallel with 2 threads each dequeueing 5M items: ``` Old - Time: 0.621s GC: 17 New - Time: 0.121s GC: 0 ``` Note that while most things get faster, there are a few operations that have a small downside. Any operation that needs to preserve items for observation (e.g. GetEnumerator, ToArray, TryPeek, etc.) essentially makes all current segments non-reusable. That's mostly no worse than before, where no segments were reusable, but since these segments get bigger, if you have strange usage pattern, such as enqueueing one item and then enumerating the queue, enqueueing another and then enumerating the queue, repeatedly, this implementation will end up allocating more memory than before. For example, in a test that enqueues10,000 items, but between adding each item it enumerates the whole queue, I get these results: ``` Old - Time: 0.404s GC: 0 New - Time: 1.091s GC: 1 ``` I'm hopeful this is not a common pattern. If it is, we may be able to find some ways to mitigate the concern.

An ECC cert is ambiguous for use, it can be any of (currently) * ECDSA * ECDH * ECMQV And probably (but not explicitly) * ECIES * EdDSA * ECQV If a user requests ECDSA we can give it to them (provided the algorithm and KU agree), but we can't know that ECDSA is ""more right"" than ECDH (which is not yet supported in corefx, but is in netfx (though not via a certificate)) for a certificate with no KeyUsage extension. Or that ECDSA is ""more right"" than EdDSA (not currently supported at all).

Is there a reason why this it is not a Task.Run(() => Open()), which would make it a bit more useful? 14308 area-System.Net Add CancellationToken overloads to async methods in System.Net.Sockets "Good day. I work with `UdpClient` and have wrapper upon it. For reading I have asynchronous method: ```c# private async Task Receive(UdpClient client, CancellationToken breakToken) { // Выход из async, если произошёл CancellationRequest breakToken.ThrowIfCancellationRequested(); UdpReceiveResult result; try { result = await client.ReceiveAsync().WithCancellation(breakToken); } catch(OperationCanceledException) { // Штатная ситуация ручной остановки Task-а } return result.Buffer; } ``` Where `WithCancellation` is my extension-method for early termination: ```c# public static async Task WithCancellation( this Task task, CancellationToken cancellationToken) { var tcs = new TaskCompletionSource(); using (cancellationToken.Register( s => ((TaskCompletionSource)s).TrySetResult(true), tcs)) if (task != await Task.WhenAny(task, tcs.Task)) throw new OperationCanceledException(cancellationToken); return await task; } ``` And after manual reading stop, when I call `Dispose`, `System.ObjectDisposedException` occurs. `CallStack`: ``` > System.dll!System.Net.Sockets.UdpClient.EndReceive(System.IAsyncResult asyncResult, ref System.Net.IPEndPoint remoteEP) Unknown System.dll!System.Net.Sockets.UdpClient.ReceiveAsync.AnonymousMethod__64_1(System.IAsyncResult ar) Unknown mscorlib.dll!System.Threading.Tasks.TaskFactory.FromAsyncCoreLogic(System.IAsyncResult iar, System.Func endFunction, System.Action endAction, System.Threading.Tasks.Task promise, bool requiresSynchronization) Unknown mscorlib.dll!System.Threading.Tasks.TaskFactory.FromAsyncImpl.AnonymousMethod__0(System.IAsyncResult iar) Unknown System.dll!System.Net.LazyAsyncResult.Complete(System.IntPtr userToken) Unknown System.dll!System.Net.ContextAwareResult.CompleteCallback(object state) Unknown mscorlib.dll!System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, object state, bool preserveSyncCtx) Unknown mscorlib.dll!System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, object state, bool preserveSyncCtx) Unknown mscorlib.dll!System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, object state) Unknown System.dll!System.Net.ContextAwareResult.Complete(System.IntPtr userToken) Unknown System.dll!System.Net.LazyAsyncResult.ProtectedInvokeCallback(object result, System.IntPtr userToken) Unknown System.dll!System.Net.Sockets.BaseOverlappedAsyncResult.CompletionPortCallback(uint errorCode, uint numBytes, System.Threading.NativeOverlapped* nativeOverlapped) Unknown mscorlib.dll!System.Threading._IOCompletionCallback.PerformIOCompletionCallback(uint errorCode, uint numBytes, System.Threading.NativeOverlapped* pOVERLAP) Unknown ``` If I understood correctly, root of error in `ReceiveAsync`, in my method of stop it to be exact. After nearly a week of suffering, I have found the reason and solution. **At first**, I looked at the `UdpClient` source code. The `ReceiveAsync` method: ```c# [HostProtection(ExternalThreading = true)] public Task ReceiveAsync() { return Task.Factory.FromAsync((callback, state) => BeginReceive(callback, state), (ar)=> { IPEndPoint remoteEP = null; Byte[] buffer = EndReceive(ar, ref remoteEP); return new UdpReceiveResult(buffer, remoteEP); }, null); } ``` **At second**, I found this post with perfect answer:http://stackoverflow.com/questions/4662553/how-to-abort-sockets-beginreceive, in which said: > To cancel a pending call to the BeginConnect() method, close the Socket. When the Close() method is called while an asynchronous operation is in progress, the callback provided to the BeginConnect() method is called. A subsequent call to the EndConnect(IAsyncResult) method will throw an ObjectDisposedException to indicate that the operation has been cancelled. And, as we can see, the original `ReceiveAsync` method return us the `ObjectDisposedException`, because `IOOperation` has not been completed after `Close` invoking. **To overcome this problem I have done like this:** New `ReceiveAsync` realization: ```c# /// /// Асинхронный запрос на ожидание приёма данных с возможностью досрочного выхода /// (для выхода из ожидания вызовите метод Disconnect()) /// /// Рабочий экземпляр класса UdpClient /// Признак досрочного завершения /// Если breakToken произошёл до вызова данного метода или в режиме ожидания /// ответа, вернёт пустой UdpReceiveResult; при удачном получении ответа-результат /// асинхронной операции чтения public Task ReceiveAsync(UdpClient client, CancellationToken breakToken) => breakToken.IsCancellationRequested ? Task.Run(() => new UdpReceiveResult()) : Task.Factory.FromAsync( (callback, state) => client.BeginReceive(callback, state), (ar) => { /// Предотвращение if (breakToken.IsCancellationRequested) return new UdpReceiveResult(); IPEndPoint remoteEP = null; var buffer = client.EndReceive(ar, ref remoteEP); return new UdpReceiveResult(buffer, remoteEP); }, null); ``` New `Dispose` realization: ```c# protected virtual void Dispose(bool disposing) { if (disposing) { this.cancelReceive?.Cancel(); this.client?.Close(); this.cancelReceive?.Dispose(); } } ``` Is my solution OK(will be cool if you add it to framework in next version) and if not can you say me how to fix it differently?" 14309 area-System.Linq Use optimized N-ary MethodCallExpression nodes for more calls. Building on #3288 from @bartdesmet this causes the arity-specialised forms of `MethodCallExpression` to be used in more cases: 1. When the arguments collection is null. 2. When the arguments collection doesn't implement `IReadOnlyList<>` It does this by pre-emptively calling `ToReadOnly` in these cases. That it's spending time building this isn't an issue, as that would have happened anyway.

It should explicitly be either true (for `ReadOnlyCollection` types) or false (for non-`ReadOnlyCollection` types) because that would assert an artificial limitation on Add/Remove/Indexer methods.

" 14325 area-System.Text Optimization: UTF8Encoding methods can probably be made faster/refactored @jamesqo commented on [Tue Aug 16 2016](https://github.com/dotnet/coreclr/issues/6759) Currently the UTF8Encoding methods are kind of a mess, and they read [ints at a time](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Text/UTF8Encoding.cs#L457-L458) rather than longs, so they're not taking full advantage of 64-bit platforms. Additionally strings have an `IsAscii()` flag [cached in the syncblk](https://github.com/dotnet/coreclr/blob/master/src/classlibnative/bcltype/stringnative.cpp#L234) that we may be able to make use of, since that will essentially let us skip any checks for non-ASCII data during the loop and make `GetByteCount` O(1). Other ideas for optimization: - Haven't proven it but I'm 99% sure that [Encoding.UTF8](https://github.com/dotnet/coreclr/blob/57b3450f4d232cd53d3b9a0f6566806d73fa4156/src/mscorlib/src/System/Text/Encoding.cs#L1519-L1524) will not be inlined, it does 3 volatile accesses and initialization? (the constructor is more likely to be inlined) This is going to harm the typical use case for people who don't cache the result, like this: ``` cs var bytes = Encoding.UTF8.GetBytes(str); bytes[0] = 0xff; str = Encoding.UTF8.GetString(bytes); // second method call to get_UTF8 ``` We should attempt to instead do something similar to [ArrayPool.Shared](https://github.com/dotnet/corefx/blob/master/src/System.Buffers/src/System/Buffers/ArrayPool.cs#L39-L43) where the one-time init logic is separated out into a new method. - Right now the virtual methods exposed in the API call another virtual method to do the heavy lifting. Maybe it would be worth duplicating some of the logic to avoid double virtual dispatch? - [Loop code size](https://github.com/dotnet/coreclr/blob/57b3450f4d232cd53d3b9a0f6566806d73fa4156/src/mscorlib/src/System/Text/UTF8Encoding.cs#L456-L497) is kinda big, which can be bad for the loop buffer. The logic to handle non-ASCII chars should be moved to outside the loop. --- @jkotas commented on [Tue Aug 16 2016](https://github.com/dotnet/coreclr/issues/6759#issuecomment-240155067) > that Encoding.UTF8 will not be inlined Agree. It would be nice to move the encoding singletons to the encoding classes where they belong, and initialize them in the static constructor of their respective class. This way the lazy initialization can be done using the more efficient static constructor trigger. > Right now the virtual methods exposed The options on what you can do about this are limited because of the encoding methods are not sealed. > logic to handle non-ASCII chars should be moved to outside the loop These kind of basic block movements are best left to profile guided optimizations - we do not have them hooked up to .NET Core yet, They are hooked up to full framework.

Can you give an example of where this would be useful? --- @stas-sultanov commented on [Fri Mar 27 2015](https://github.com/dotnet/coreclr/issues/542#issuecomment-86966435) Sure. Here is an example from one of my projects: A ConvertEx class which provides a set of methods to convert data from base-n string to byte array and vice-versa. This class has a lot of methods like: ``` C# public static TryResult TryToBase16String(byte[] data, int offset, int length) public static TryResult TryFromBase16String(string data, int offset, int length) ``` for this methods i'd like to use single method that checks arguments ``` C# private static void CheckArguments(IReadOnlyCollection data, int offset, int length) { if (data == null) throw new ArgumentNullException(@""data""); if (length < 0) throw new ArgumentOutOfRangeException(@""length"", length, @""Is less than 0.""); if (offset < 0) throw new ArgumentOutOfRangeException(@""offset"", offset, @""Is less than 0.""); if (offset > (data.Count - length)) throw new ArgumentOutOfRangeException(@""data"", data.Count, @""Offset plus length is greater than the length of data.""); } ``` But unfortunately it is not possible because byte[] and string has only one common interface `IEnumerable`. Use `IEnumerable` and get length via `Count()` method is not an option due to performance consideration. --- @pharring commented on [Fri Mar 27 2015](https://github.com/dotnet/coreclr/issues/542#issuecomment-86985851) A non-generic overload of CheckArguments would solve this, of course. --- @stas-sultanov commented on [Fri Mar 27 2015](https://github.com/dotnet/coreclr/issues/542#issuecomment-87003680) of course it would, and that it is the way it is made now. :) but it dose not looks like a good design. maybe example is not good enough, however i strongly believe that this small change would made coreclr more versatile. --- @SamuelEnglard commented on [Sun Mar 29 2015](https://github.com/dotnet/coreclr/issues/542#issuecomment-87472249) Just a quick point but unless I'm wrong array's don't implement `IReadOnlyList` so you'd still have to use the `Enumerable.Count()`. Do access the length/count of both an array and string in an efficient manner we'd have to `Enumerable.Count()` smarter. It already looks for types that implement `ICollection` or `ICollection` and uses the `Count` property instead of looping. If we add a shortcut for `IReadOnlyList` to that too then you could do what you want. --- @stas-sultanov commented on [Mon Mar 30 2015](https://github.com/dotnet/coreclr/issues/542#issuecomment-87485509) Arrays do implement `IReadOnlyList`, please take a look at comments of [Array](https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Array.cs) class.

But no Move method that can efficiently move an item from one position to another. What we have to do is [RemoveAt and Insert](https://github.com/dotnet/corefx/blob/master/src/System.ObjectModel/src/System/Collections/ObjectModel/ObservableCollection.cs#L200). It means two copies of big chunks of memory instead of one. The worst case is when both **from** and **to** are close to each other and to the beginning of a large list. What could be done with one copy of a few items becomes two copies of almost the whole list. In my implementation of ObservableCollection.MoveItem I had to get the underlying `List`, retrieve via reflection :see_no_evil: its array and do the work myself. So.. **I propose adding new Move method to generic List with the following signature:** ``` C# public void Move(int oldIndex, int newIndex); ``` --- @omariom commented on [Sun Jun 21 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-113963719) cc: @KrzysztofCwalina --- @OtherCrashOverride commented on [Sun Jun 21 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-113967256) Isn't this what LinkedList is for? --- @omariom commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114040328) LinkedList is quite different in its capabilities. Its elements can't be accessed by position, its layout is not cache friendly etc. --- @hadibrais commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114066363) While such method can be added to the generic list and is really useful, it cannot be utilized from the existing **ObservableCollection.Move** method you referenced. That's because three state changes have to be reported: **NotifyCollectionChangedAction.Remove**, **NotifyCollectionChangedAction.Add** and **NotifyCollectionChangedAction.Move**. Also the intermediate states have to be captured and made available to any listeners. Regardless, such efficient method is really useful and should be offered by the generic List. It's also easy to implement. --- @omariom commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114071250) I mentioned ObservableCollection.MoveItem just as an example where such method could be used. Actually there are other cases where Move could be beneficial. > That's because three state changes have to be reported: NotifyCollectionChangedAction.Remove, NotifyCollectionChangedAction.Add and NotifyCollectionChangedAction.Move. Collection (which is the base class) doesn't report any actions. So nothing changes in terms of reporting. --- @OtherCrashOverride commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114083702) List is not intended for performance with random inserts and deletes. Adding 'move' would just encourage improper use of the class. Move is a heavy weight function when type of List is a struct/valuetype. If there is a language where there is a precedence of having Move on a List it would be worth examining. Neither C++ std::vector nor Java 8 have any such notion. > In my implementation of ObservableCollection.MoveItem I had to get the underlying List, retrieve via reflection its array and do the work myself. It would also be helpful to post the code somewhere as an example of what is wanted. --- @omariom commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114095876) @OtherCrashOverride Something like this: ``` C# public void Move(int oldIndex, int newIndex) { if ((uint)oldIndex >= (uint)_size) { ThrowArgumentOutOfRange(""oldIndex""); } if ((uint)newIndex >= (uint)_size) { ThrowArgumentOutOfRange(""newIndex""); } if (newIndex == oldIndex) return; T item = _items[oldIndex]; if (newIndex < oldIndex) { Array.Copy(_items, newIndex, _items, newIndex + 1, oldIndex - newIndex); } else { Array.Copy(_items, oldIndex + 1, _items, oldIndex, newIndex - oldIndex); } _items[newIndex] = item ; _version++; } ``` --- @omariom commented on [Sat Jul 02 2016](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114097129) > List is not intended for performance with random inserts and deletes. Yes, but we already have **RemoveAt** and **Insert** methods which allow random inserts and deletes. And they are actually used to implement move semantics. --- @OtherCrashOverride commented on [Mon Jun 22 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-114101837) I would suggesting creating a pull request with the code and some tests. You should also include code to benchmark performance with Move versus RemoveAt / Insert. --- @masonwheeler commented on [Fri Jun 26 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-115775692) @OtherCrashOverride The performance benefits are obvious when you think about worst cases. For example, imagine a list with a few thousand items in it, and the operation you want to perform is `Move(10, 20);` With `RemoveAt` and `Insert`, you end up having to shift (essentially) all items in the list... twice. With the proposed `Move` method, you would have to shift 9 items once. --- @OtherCrashOverride commented on [Fri Jun 26 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-115823035) > The performance benefits are obvious when you think about worst cases. We really need to see benchmarks before we start speculating. In theory, it should be faster. The reality will come down to what the runtime does behind the scenes. For most cases LinkedList is probably a better choice. The use case for this is where you require the data to be sequential in memory. A specific example is when dealing with a GPU. Vertex data is typically very large structs packed into an array. It is also not uncommon to manipulate the data elements in real time. This proposal may benefit that specific scenario. We still require a benchmark to validate the claim. --- @KrzysztofCwalina commented on [Fri Jun 26 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-115827288) I think some kind of ""move"" API is worth exploring. But I think it would be great if somebody thought about a more general API than simple ""move one items from here to there"". For example, what if I want to move a slice/range? what if I want to swap two ranges? What if I want to round robin move three items? BTW, I am not proposing that we actually implement all these, often corner case, scenarios, but it would be good to have a good overview of the ""move"" scenarios and chose to implement the ones that are common and where we can get good performance improvement while preserving simplicity. --- @OtherCrashOverride commented on [Fri Jun 26 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-115850684) Upon further reflection, there is an issue here in that you can not actually get at the sequential data (for p/invoke) without exposing the internal array. With that in mind, maybe 'Move' should be proposed for 'Array'. List could then make use of that functionality without breaking encapsulation as exposing the internal array storage would do. Alternatively, a new ArrayList (or some other name) class could be introduced that guarantees array storage and exposes the internals. This, however, seems less than ideal. https://msdn.microsoft.com/en-us/library/system.collections.arraylist%28v=vs.110%29.aspx --- @AdamSpeight2008 commented on [Sat Jun 27 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-116131277) Why not just swap the contents? ``` c# public void Swap( this T a, T ) { T tmp = a; a = b; b = a; } ``` --- @masonwheeler commented on [Sat Jun 27 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-116132546) @AdamSpeight2008 Because that would only be a valid equivalent if the new index was adjacent to the old index. Let's say we have a lit of ints, like so: `0, 1, 2, 3, 4, 5, 6, 7, 8, 9` Swapping 1 and 5 would result in `0, 5, 2, 3, 4, 1, 6, 7, 8, 9` whereas executing the hypothetical `Move(1, 5)` would result in: `0, 2, 3, 4, 1, 5, 6, 7, 8, 9` As you can see, they're completely different operations. --- @AdamSpeight2008 commented on [Sat Jun 27 2015](https://github.com/dotnet/coreclr/issues/1165#issuecomment-116137212) @masonwheeler Should the result of `Move( 1, 5)` be `0, 2, 3, 4, 5, 1, 6, 7, 8, 9` What should the resulf of `Move( 5, 1)` ? then same?

The receive buffer is rented for the lifetime of the websocket, whereas the send buffer is rented only for the duration of a send. By switching to using ArrayPool, memory consumption when many websockets are being used should be less, as they will only take up the space for the send buffer while it's in use. cc: @benaadams, @CIPop, @davidsh, @anurse 14341 area-System.Collections Concurrent_Enqueue_TryPeek_TryDequeue_AllItemsSeen failing sporadically Since #14254 was merged, the Concurrent_Enqueue_TryPeek_TryDequeue_AllItemsSeen test has failed a few times, but only on Unix.

zero](https://ci.dot.net/job/dotnet_corefx/job/master/job/code_coverage_windows/Code_Coverage_Report/) 14354 area-System.Numerics Proposal: Add System.HashCode to make it easier to generate good hash codes. "# Update 6/16/17: Looking for volunteers The API shape has been finalized. However, we're still deciding on the best hash algorithm out of [a list of candidates](https://github.com/dotnet/corefx/issues/14354#issuecomment-305028686) to use for the implementation, and we need someone to help us measure the throughput/distribution of each algorithm. If you'd like to take that role up, please leave a comment below and @karelz will assign this issue to you. # Update 6/13/17: Proposal accepted! Here's the API that was approved by @terrajobst at https://github.com/dotnet/corefx/issues/14354#issuecomment-308190321: ```cs // Will live in the core assembly // .NET Framework : mscorlib // .NET Core : System.Runtime / System.Private.CoreLib namespace System { public struct HashCode { public static int Combine(T1 value1); public static int Combine(T1 value1, T2 value2); public static int Combine(T1 value1, T2 value2, T3 value3); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7, T8 value8); public void Add(T value); public void Add(T value, IEqualityComparer comparer); [Obsolete(""Use ToHashCode to retrieve the computed hash code."", error: true)] [EditorBrowsable(Never)] public override int GetHashCode(); public int ToHashCode(); } } ``` The original text of this proposal follows. # Rationale Generating a good hash code should not require use of ugly magic constants and bit twiddling on our code. It should be less tempting to write a bad-but-concise `GetHashCode` implementation such as ```cs class Person { public override int GetHashCode() => FirstName.GetHashCode() + LastName.GetHashCode(); } ``` # Proposal We should add a `HashCode` type to enscapulate hash code creation and avoid forcing devs to get mixed up in the messy details. Here is my proposal, which is based off of https://github.com/dotnet/corefx/issues/14354#issuecomment-305019329, with a few minor revisions. ```cs // Will live in the core assembly // .NET Framework : mscorlib // .NET Core : System.Runtime / System.Private.CoreLib namespace System { public struct HashCode { public static int Combine(T1 value1); public static int Combine(T1 value1, T2 value2); public static int Combine(T1 value1, T2 value2, T3 value3); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7); public static int Combine(T1 value1, T2 value2, T3 value3, T4 value4, T5 value5, T6 value6, T7 value7, T8 value8); public void Add(T value); public void Add(T value, IEqualityComparer comparer); public void AddRange(T[] values); public void AddRange(T[] values, int index, int count); public void AddRange(T[] values, int index, int count, IEqualityComparer comparer); [Obsolete(""Use ToHashCode to retrieve the computed hash code."", error: true)] public override int GetHashCode(); public int ToHashCode(); } } ``` ## Remarks See @terrajobst's comment at https://github.com/dotnet/corefx/issues/14354#issuecomment-305019329 for the goals of this API; all of his remarks are valid. I would like to point out these ones in particular, however: - The API **does not need** to produce a strong cryptographic hash - The API will provide ""a"" hash code, but not guarantee a particular hash code algorithm. This allows us to use a different algorithm later or use different algorithms on different architectures. - The API will guarantee that within a given process the same values will yield the same hash code. Different instances of the same app will likely produce different hash codes due to randomization. This allows us to ensure that consumers cannot persist hash values and accidentally rely on them being stable across runs (or worse, versions of the platform)." 14355 area-System.Net Port windows authentication for HttpListener fixes #13903 Classification of changes - Ported authentication from full framework to core - WDigest protocol is not ported, as it's disabled from Windows 8.1. - Added tests for basic authentication, other protocols require infrastructure from CI. cc @CIPop @davidsh @stephentoub @karelz 14356 area-System.Security [AWS Linux][unsupported] X509Certificate2 fails on AWS Linux "How do I load a X509certificate on netcore?

This option enables or disables build of native binaries portable over Linux distros based on glibc. I have also modified the build-native.sh behavior for the staticLibLink option. Before, if you ran build with this option and then later on ran the build without this option, it was still considered as being set since the previous value was cached. With my change, it rebuilds the binaries any time you change the option. 14363 area-System.Net Use ArrayPool for multiple buffers in CurlHandler CurlHandler currently has two potentially large byte[] buffers: - When sending request data, it allocates a buffer to transfer data from the request to libcurl, typically 16K (unless the request content is known to be smaller than that). - When transferring response data, libcurl offers up data in large chunks, and we need to take all or none of it at a time. If a response read on the response stream asks for less than what libcurl proferred, we need to buffer the remainder, typically up to 16K in size. Currently these buffers are allocated per request. This commit changes them to come from ArrayPool. cc: @geoffkizer, @davidsh, @cipop 14364 area-System.Collections Fix ConcurrentBag enumeration undefined behavior ConcurrentBag.GetEnumerator used to copy all of the contents into a List and then return that List's enumerator. As part of some recent optimizations, I changed that to use an array instead of a list. But array's enumerator has different semantics for the undefined case of accessing Current after MoveNext returns false. Initially I thought we'd just accept the breaking change, but as it's simple to address and as the change does introduce an exception where there wasn't previously one, I've changed my mind and am just adding a simple enumerator to address the discrepancy.

If that is ok with you? I would like to start minimally with implementation, and instead focus on ensuring complete tests are in place and ideally perf tests so we can establish a baseline. From that we can move on with optimizations. So first question, is what tests should be added? As I see we need at least three different scenarios: * Value type without references i.e. `int` (already there) * Reference type i.e. `string` * Value type with references i.e. custom `struct` Additionally, there needs to be tests that cover alignment issues etc. I assume. cc: @karelz Closes https://github.com/dotnet/corefx/issues/13915 https://github.com/dotnet/corefx/issues/14189 14398 area-System.Runtime Investigate queueing string references for StringBuilder "Currently, in `StringBuilder.Append(string)` we copy all of the characters of the input string to our internal buffers. Then, we copy all of these characters again to the output string if `ToString` is called. So basically, we're copying each input string twice. We can reduce this to 1 copy. Instead of eagerly copying the string when `Append` is called, we can queue it up into a list of string references we have. Then, during `ToString`, we will copy the part from our char buffers before that string, copy the string, then copy the part from our buffers before the next string, etc. Here is a visualization: ```cs new StringBuilder() .Append('a') .Append(""reallylongstring"" + new string(Enumerable.Repeat('g', 100).ToArray())) .Append(','); // Before InternalBuffers: ['a', 'r', 'e', 'a', ... 'g', 'g', '.'] // After InternalBuffers: ['a', '.'] StringQueue: [""reallylongstringggggg...gg""] // Only 8 bytes to store! ``` It is a little overly simplistic because StringBuilder actually uses a linked list of char buffers for internal storage, but I hope the point still gets across. ## Downsides - It will complicate the indexer logic more - We will have to add an extra field or 2 to `StringBuilder` - The string reference itself may be more expensive to store than the string's characters - However, we can easily work around this by checking the length of the string, and calculating whether that takes up 8 bytes (the size of a 64-bit reference) or more. If yes, then we queue it; if no, then we copy its individual characters. ## Other Notes I made a proof-of-concept PR last month to corefxlab, so you can see more how this is implemented if you're interested: https://github.com/dotnet/corefxlab/pull/976" 14403 area-System.IO CreateText always creates a new file while documentation says it creates OR opens "At https://docs.microsoft.com/en-us/dotnet/core/api/system.io.file#System_IO_File_CreateText_System_String_ documentation says, that: CreateText(String) Creates or opens a file for writing UTF-8 encoded text.

Addition of new Method ```C# namespace System.Collections.Generic { public class HashSet { public static IEqualityComparer> CreateSetComparer( IEqualityComparer comparer); } } ``` This method will return an `IEqualityComparer>` that uses the `IEqualityComparer` passed to it in comparing elements to determine equality of hash-sets. The comparer returned will consider two sets equal iff for each element in either there is an element in the other that `comparer` considers equal to it. Optimised paths may only be taken if they give the same result as this. If `comparer` is null, the method will treat this as if `EqualityComparer.Default` had been passed to it. The comparer will produce a hash code for sets as follows: 1. If the set is `null` the hash code is `0`. 2. Otherwise start with a seed value. For each value that `comparer` considers distinct, exclusive-or `comparer.GetHashCode(element)` with it. (The use of exclusive-or allows this algorithm to be agnostic to element order). ## 2. Obsolescence of Current `CreateSetComparer` Method ```C# namespace System.Collections.Generic { public class HashSet { [System.Obsolete(""This method can produce inconsistent results. Use CreatSetComparer(IEqualityComparer"")] public static IEqualityComparer> CreateSetComparer(); } } ``` The existing `CreateSetComparer` method has a minor design and major implementation issue. The design issue is that it lacks the ability to select the `IEqualityComparer` to use. If this was the only problem it could work as an overload equivalent to `CreateSetComparer(null)` but it also has implementation flaws resulting in a non-commutative `Equals()` and disagreement between `Equals()` and `GetHashCode()`. However fixing it would break some cases that it can (in disagreement with how it is specified) serve to usefully determine set-equality of two sets in respect of their own comparers, if those comparers are the same. See #12560 Since it can't be fixed without considerable breaks, and both the specified behaviour and the other type of comparison it sometimes makes are offered by the new method (with a clear way of indicating which is wanted), this method should be obsoleted. (Fixing it to behave as specified could be considered after it has been obsolete for some time, as an alternative to deleting it)." 14417 area-System.Runtime Environment.GetEnvironmentVariables() should give back DictionaryEntry, not KeyValuePair A recent change regressed Environment.GetEnvironmentVariables().

Fixes #13910 cc @JonHanna, @stephentoub, @VSadov 14436 area-System.Data SqlConnection.RetrieveStatistics should always return DictionaryEntry ### Summary If the `IDictionary` returned from `SqlConnection.RetrieveStatistics()` is cast to `IEnumerable`, its enumerator will yield `KeyValuePair` items instead of `DictionaryEntry` items, which is a behavior difference from the full framework. This PR addresses the behavior difference by changing `IEnumerable.GetEnumerator` to return a `DictionaryEntry` enumerator to match the behavior of the full framework. ### Details To break the dependency on the non-generic collections, `SqlConnection.RetrieveStatistics()` was changed to return an instance of a `Hashtable`-compatible subclass of `Dictionary` instead of returning a `Hashtable` instance (#7691). However, a subtle behavior difference was missed (see #14417 for a similar issue). - `Dictionary`'s implementation of [`IDictionary.GetEnumerator`](https://github.com/dotnet/coreclr/blob/04d6bd105ade5f6189a15a6dbb59b082613429a1/src/mscorlib/src/System/Collections/Generic/Dictionary.cs#L703-L705) returns a `DictionaryEntry` enumerator, which matches `Hashtable`. Since the return type of `RetrieveStatistics` is `IDictionary`, the default behavior of enumerating the result as-is (without casting away from `IDictionary`) is the same as `Hashtable`. - However, if the result is cast from `IDictionary` to `IEnumerable`, `Dictionary`'s [`IEnumerable.GetEnumerator`](https://github.com/dotnet/coreclr/blob/04d6bd105ade5f6189a15a6dbb59b082613429a1/src/mscorlib/src/System/Collections/Generic/Dictionary.cs#L601-L603) implementation will return a `KeyValuePair` enumerator, which does not match `Hashtable`'s behavior of returning a `DictionaryEntry` enumerator. This PR changes the `Hashtable`-compatible subclass's `IEnumerable.GetEnumerator` implementation to return a `DictionaryEntry` enumerator to match `Hashtable`. Updated tests pass on the full framework, fail before the src changes, and pass after the src changes. Note that this is technically a breaking change from .NET Core 1.0/1.1. However, publicly available [telemetry](https://apisof.net/catalog/System.Data.SqlClient.SqlConnection.RetrieveStatistics()) shows 0% usage of this API, and the default behavior of enumerating the resulting `IDictionary` as-is without casting to `IEnumerable` isn't changing, which makes me think this is a fairly low-risk change that's worth making to be more compatible with the full framework. An alternative fix would be to just re-establish the direct dependency on `System.Collections.NonGeneric` and change this back to returning `Hashtable` for the next version of .NET Core since some of `System.Data.SqlClient`'s dependencies now depend on `System.Collections.NonGeneric` (due to the .NET Standard 2.0 effort), which would allow deleting the private `StatisticsDictionary` subclass. If this is preferred, I can update the PR. cc: @saurabh500, @stephentoub 14437 area-System.Net Test failure: System.Net.Http.Functional.Tests.PostScenarioTest/PostLongerContentLengths_UsesChunkedSemantics(contentLength: 64512) Opened on behalf of @jiangzeng The test `System.Net.Http.Functional.Tests.PostScenarioTest/PostLongerContentLengths_UsesChunkedSemantics(contentLength: 64512)` has failed.

Thanks!" 14443 area-System.Linq Faster iterator-unfriendly System.Linq methods Thanks to [a recent PR](https://github.com/dotnet/corefx/pull/14418), I knew about a curious bipartition in the performance of the iterator-optimised (i.e., relying on `yield` or `Yield`) methods: what performs well in an iterating scenario (e.g., `foreach(var item in YieldMethod()){ }`) might perform bad in a returning one (e.g., `var outputCollection = YieldMethod();`) and vice versa. In that PR, I suggested an improved version of `System.Linq.Intersect`. The new version delivers notably better (around 40% faster under a wide variety of conditions on a not-too-powerful computer) and worse performances for returning (e.g., `var output = collection1.Intersect(collection2);`) and iterating (e.g., `foreach(var item in collection1.Intersect(collection2)){}`) scenarios, respectively. My proposal couldn't go through because of not representing a real improvement (even if all the performance gains would be bigger than the losses, a relevant number of scenarios performing notably worse wouldn't be acceptable). Although modifying the existing `System.Linq.Intersect` isn't reasonable, creating an alternative method performing notably faster when getting the collection (rather than right away iterating through it) sounds fine to me. Do you want to rely on an alternative which performs reasonably well in any case? Use `System.Linq.Intersect`. Are you sure that you want to get the collection (and iterate through it right afterwards or at a later point or even don't iterate through it at all)? Use the notably faster new alternative. Before going ahead with my proposal, I want to highlight the tremendous importance of the `System.Linq` methods, which are being systematically used on virtually any situation. Note that I am not the kind of programmer liking very small code and always relying on this kind of approaches; I don't care about writing much bigger codes if they perform better or are clearer or easily modifiable. But I do use `System.Linq` methods on a regular basis; at least, some of them. Getting notably-better-performing versions of these methods would have a notable impact on my coding approach. Actually, I wasn't using `Intersect` too much lately precisely because of having confirmed its not-that-good-performance under many different conditions. What I am proposing is a new `class` (e.g., `System.LinqFast`) including returning-scenario-optimised versions for all the `System.Linq` methods. Although I have only analysed the `Intersect` and `Except` (virtually identical to `Intersect`) codes, can safely assume that equivalent ideas are applicable to the other methods because of the observed noticeable performance differences between the iterating/returning scenarios. That is, either the current methods are adequately optimised for iteration purposes (+ likeliness of a different version performing notably better for the returning-scenario) or they might be further optimised on this front (also a positive output for this proposal). As an example of the kind of modifications which are likely to define each of the aforementioned scenarios, take a look at the `Intersect` codes in my aforementioned PR: Original code (by bearing in mind that `comparer` is always `null` and [the definition of the Set internal class](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Set.cs)): ```C# private static IEnumerable IntersectIterator(IEnumerable first, IEnumerable second, IEqualityComparer comparer) { Set set = new Set(comparer); foreach (TSource element in second) { set.Add(element); } foreach (TSource element in first) { if (set.Remove(element)) { yield return element; } } } ``` Notably-faster-for-returning-scenarios alternative: ```C# private static IEnumerable IntersectIteratorNew(IEnumerable first, IEnumerable second) { IEnumerable first2 = first.Distinct(); IEnumerable second2 = second.Distinct(); foreach (TSource element in first2) { if (second2.Contains(element)) { yield return element; } } } ``` There are also other approaches which are appreciably faster than the current code for returning scenarios. For example: ```C# private static IEnumerable IntersectIteratorNew2(IEnumerable first, IEnumerable second) { List done = new List(); foreach (TSource element in first) { if (done.Contains(element)) continue; foreach (TSource element2 in second) { if (done.Contains(element2)) continue; if ((element == null && element2 == null) || element2.Equals(element)) { done.Add(element); yield return element; } } } } ``` The underlying idea to these codes is that the `yield` statement (when being called inside an iterator) penalises the reliance on external (iterating) methods (e.g., `Contains`). This fact makes a-priori-worse-performing alternatives (e.g., adding/removing items to/from a third collection, rather than loops + calling the efficient `Contains` method) ideal under iterating conditions, but certainly improvable for other scenarios. As far as this proposal implies quite relevant modifications and I don't know what are the .NET team/community positions on this front, I will better not analyse other methods for the time being. In case of seeing some positive feedback (and certainly before writing the definitive proposal), I wouldn't mind to analyse other `System.Linq` methods (by bearing in mind that `Except` is very similar to `Intersect` and, consequently, all the aforementioned ideas apply to it too). In case of deciding to go ahead, I would like to take care of the implementation myself. 14444 area-System.Linq Reduce time taken to test StackGuard and move to innerloop. We have a test that verifies that `Expression` compilation is protected against stack overflow in the case of compiling deep expression trees, but forcing a case that would cause such a problem by necessity requires a large tree that takes a long time to compile, so the test is outerloop only. Forcing the compilation to happen on the smallest possible stack reduces the size of tree that would risk a stack overflow, and so can test the same functionality in less than a second. Do this, and move the test to innerloop. 14445 area-System.Net System.Net.Http 4.3.0 oob conflicts with framework assembly with target net462 "Hi, These are the steps to reproduce the issue : - Create a classic desktop library project in 462 - Add a nuget package ""Microsoft.AspNetCore.Authentication"" version ""1.1.0"" => This package targets both .NETFramework4.5.1 and .NETStandard1.3 with a dependency on NETStandard.Library 1.6.1 and has a framework assembly dependency on System.Net.Http for 4.5.1 ``` ``` => NETStandard.Library 1.6.1 has a dependency on System.Net.Http 4.3.0 for target NETStandard1.3 - In Class1.cs, add public static HttpClient client = new HttpClient(); // should bind to version 4.1.1.0 - nuget pack the csproj (using nuget latest version 3.5.0 rtm or 3.6.0) - Create a core console app project targerting net462 - Reference the newly created package - In Program.cs, add Console.WriteLine(ClassLibrary2.Class1.client.GetType().FullName); - Run - An exception FileNotFoundException is thrown about ""System.Net.Http, Version=4.1.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"" From what I understand, all binaries should be using System.Net.Http 4.3.0 with a binding redirect from framework version. project.lock.json shows that System.Net.Http is resolved from frameworkAssemblies ``` "".NETFramework,Version=v4.6.2"": { ""ClassLibrary2/1.0.0"": { ""type"": ""package"", ""dependencies"": { ""Microsoft.AspNetCore.Authentication"": ""1.1.0"" }, ""compile"": { ""lib/net462/ClassLibrary2.dll"": {} }, ""runtime"": { ""lib/net462/ClassLibrary2.dll"": {} } }, ""Microsoft.AspNetCore.Authentication/1.1.0"": { ""type"": ""package"", ""dependencies"": { ""Microsoft.AspNetCore.DataProtection"": ""1.1.0"", ""Microsoft.AspNetCore.Http"": ""1.1.0"", ""Microsoft.AspNetCore.Http.Extensions"": ""1.1.0"", ""Microsoft.Extensions.Logging.Abstractions"": ""1.1.0"", ""Microsoft.Extensions.Options"": ""1.1.0"", ""Microsoft.Extensions.WebEncoders"": ""1.1.0"", ""NETStandard.Library"": ""1.6.1"" }, ""frameworkAssemblies"": [ ""System.Net.Http"" ], ``` If I create another classic desktop 462 project, add System.Net.Http 4.3.0 and reference this project from the core console app. Then, project.lock.json is the same, but System.Net.Http 4.1.1.0 is copied to bin directory and a binding redirect is correctly generated as expected. ``` ``` If you remove this last reference from project.json, rebuilding the project leave the binding redirect and assembly.

I can repro the issue with a single call to WriteAsync in the test. The fix is to add lock() statements to the two areas that are in the race condition so they both don't modify the same state. The Dispose calls IdentityTransform.TransformFinalBlock class (which is a test class) and can cause `len` to be -5 in the error case: ```c# private sealed class IdentityTransform : ICryptoTransform { ... private readonly bool _canTransformMultipleBlocks; private long _writePos, _readPos; private MemoryStream _stream; public byte[] TransformFinalBlock(byte[] inputBuffer, int inputOffset, int inputCount) { _stream.Position = _writePos; _stream.Write(inputBuffer, inputOffset, inputCount); _stream.Position = _readPos; >>-5 long len = _stream.Length - _stream.Position; byte[] outputBuffer = new byte[len]; _stream.Read(outputBuffer, 0, outputBuffer.Length); _stream = new MemoryStream(); _writePos = 0; _readPos = 0; return outputBuffer; } ```` 14480 area-System.Net ManagedWebSocket HTTP scenarios implementation Tracking the implementation of the following items: - [ ] ClientWebSocketOptions.UseDefaultCredentials - [ ] ClientWebSocketOptions.Credentials - [ ] ClientWebSocketOptions.Proxy - [ ] ClientWebSocketOptions._sendBufferSize 14481 area-System.Net Adding tracking issue for ManagedWebSocket missing features.

We've been using a local version of this attribute in many of our test assemblies in order to control what shows up in our code coverage reports. The public version we are now exposing does not allow the attribute to be applied to assemblies, so our test assemblies cannot use the public version of the attribute. Test assemblies can continue using the internal version of the attribute, but then we get ambiguity warnings from the compiler, which we need to suppress. We could potentially just allow the .NET Core version of the attribute to be applied to assemblies, even though the .NET Framework version doesn't allow it. @weshaggard 14489 area-Infrastructure Use static configurations for building a vertical Disables the dynamic determination of groups and uses the static configuration files produced by src\Tools. /cc @weshaggard @ericstj 14491 area-Infrastructure Temporarily disable package publishing This is currently breaking official builds in the branch because we don't produce the correct set of packages from the build right now.

"I'm working on localization of dotnet/cli itself and I hit an issue where csc on .NET Core on Windows can give me garbled text if I'm on a non English machine with corresponding satellite assemblies present. The root cause is https://github.com/dotnet/corefx/issues/10054. I'm going to have to ensure that msbuild, cli, and roslyn all call Encoding.RegisterProvider(CodePagesEncodingProvider.Instance) before outputting anything to the console in non-English locales. I'm concerned that this pain point for .NET Core on Windows is not worth the benefit of making the code page data ""optional"". I say optional in quotes because the shared framework carries System.Text.Encoding.CodePages.dll and if I publish a standalone .NET Core app with our tools and the usual steps, System.Text.Encoding.CodePages is copied in to my app folder. Is anyone actually getting the benefit of not having System.Text.Encoding.CodePages? Given the high likelihood of System.Text.Encoding.CodePages.dll being present in practice, could System.Console light-up on it somehow? i.e. If it's there next to System.Console.dll, then use it regardless of whether register has been called whenever the console code page is not UTF8 and text outside ASCII range is written? @terrajobst @tarekgh @karelz FYI @piotrpMSFT @cdmihai @jaredpar " 14501 area-Infrastructure Update projects to netcoreapp2.0 / netstandard2.0 / net461 We need to update our projects to build against these new monikers and package as the same.

Also most operation do nothing if segment has zero length. And user code can use `IsEmpty` property to improve performance for empty segment.

So far, native memory is typically represented by a SafeHandle (e.g., SafeMemoryMappedViewHandle) or an IntPtr (e.g., as returned by Marshal.AllocHGlobal). It will probably a common use case to create a (ReadOnly)Span\ from these. *Proposal:* Add a constructor overload that accepts an IntPtr and a length: ```diff public struct Span { + public Span(IntPtr pointer, int length) { ... } public struct ReadOnlySpan { + public ReadOnlySpan(IntPtr pointer, int length) { ... } ``` *Example Usage 1:* ```csharp int length = 4096; SafeHandle handle = VirtualAlloc(IntPtr.Zero, new IntPtr(length), 0x3000, 0x04); bool addedRef = false; try { handle.DangerousAddRef(ref addedRef); MyMethod(new Span(handle.DangerousGetHandle(), length)); } finally { if (addedRef) { handle.DangerousRelease(); } } ``` *Example Usage 2:* ```csharp int length = 512; IntPtr hglobal = Marshal.AllocHGlobal(length); try { MyMethod(new Span(hglobal, length)); } finally { Marshal.FreeHGlobal(hglobal); } ``` There is currently a constructor overload that accepts a void* and a length, and an IntPtr can of course easily be converted to a void* using the IntPtr.ToPointer method. However, this requires `true` and is the only instance in the API surface where an `unsafe` code block is required. It would be nice if spans could be used without `unsafe` code blocks. IMHO requiring `unsafe` when working with native memory doesn't really make things safer since there are already methods like Marshal.ReadInt32 that can be used to read or write arbitrary native memory through an IntPtr. 14508 area-System.Linq Update S.L.E to compile when NO_FEATURE_STATIC_DELEGATE and FEATURE_MAKE_RUN_METHODS are defined 14509 area-System.Linq Remove enum → underlying unwrapping in expression instruction ctors Incorrect (should be `type.GetNonNullableType().GetTypeInfo().IsEnum ?

Now imagine we have a collection of `A`: ```cs var list = new List() { new A { Va = 1 }, new A { Va = 2 } }; ``` If we wanted to cast this list to `B`, one would assume to use `list.Cast().ToList()`. However, we are met with `InvalidCastException: Unable to cast object of type 'A' to type 'B'.` It seems that the source of this error is [from here](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Cast.cs#L51) where `CastIterator` iterates over each item as `object`. By changing this to `dynamic`, `.Cast()` works as expected with overloaded operators.

The IncrementalHash class is a simple wrapper for the real implementation [HashProvider](https://github.com/dotnet/corefx/blob/master/src/Common/src/Internal/Cryptography/HashProvider.cs), but users can't implement HashProvider as it is internal, and the IncrementalHash wrapper is not extensible as well. In good design, I'd want hash algorithms to be exchangeable in an API, which is possible with HashAlgorithm, but not with IncrementalHash or HashProvider. Arguably, most people could take in [HashAlgorithmName](https://github.com/dotnet/corefx/blob/master/src/System.Security.Cryptography.Primitives/src/System/Security/Cryptography/HashAlgorithmName.cs) and give it to IncrementalHash.Create(), but that does not support third party hash algorithm implementations. I'd propose the API is refactored once more (while IncrementalHash is not widely used), to support integration of third party stateful/incremental hash algorithms. 14571 area-System.Reflection SignatureTypeEncoder missing API for encoding custom modifiers on void* 14572 area-System.Runtime Introduce System.IString interface and implement it on System.String "### Proposal Introduce an interface called ```IString``` in the System namespace. The purpose of the interface is to identify string-like objects and provide a minimal set of methods over them. The native ```System.String``` type should implement this new interface. ### Motivation The motivation for this proposal is to allow library authors to implement efficient alternative representations of 'string-like' objects. An ```IString```, therefore, represents the essence of a string: An *immutable*, *finite* sequence of Unicode characters that supports enumeration and random access. ### Rationale In code which does heavy text processing, strings are invariably the most frequently allocated type. Many strings are short-lived, but few are ""novel"". By ""novel"", I mean that most strings are realized by transforming existing data - they don't spring into existence out of thin air. Some common examples: 1. A substring of an existing string. 2. A concatenation of two or more existing strings or characters. 3. The result of de-serializing a stream via an encoding. In each of these cases (and many others), since public APIs tend to be built around the ```System.String``` primitive, early realization of the transformations is unavoidable. Both callers and implementors are forced to use the primitive representation, even when it would be inefficient. e.g. Trimming off the last character of a string by creating a substring with length = Length - 1. By using ```IString``` instead of ```string``` in both the public APIs and internal implementations, library authors have an opportunity to reduce these hard-to-avoid allocations. Indeed, if we had something like this from the beginning in Roslyn, I feel we would have used it extensively. ### Details The proposed definition of IString is: ```C# namespace System { using System.Collections.Generic; interface IString : IEnumerable { char this[int index] { get; } int Length { get; } } } ``` Note that this definition is very similar to ```System.Collections.Generic.IReadOnlyList``` except: 1. The length property is named ```Length``` instead of ```Count```, and 2. It's easier to type (fewer chars) and discover (lives in the System namespace) ### Examples By way of an example for an alternative representation of a string-like thing using ```System.IString```, here is a canonical ""SubString"" implementation: ```C# using System; using System.Collections; using System.Collections.Generic; sealed class SubString : IString { private readonly IString _original; private readonly int _start; private readonly int _length; public SubString(IString original, int start, int length) { // TODO: Decide whether to throw on invalid start/length or just clamp the values. _original = original; _start = start; _length = length; } public char this[int index] { get { if (index < 0 || index >= _length) { throw new IndexOutOfRangeException(nameof(index)); } return _original[_start + index]; } } public int Length => _length; public IEnumerator GetEnumerator() { // TODO: If _start is zero, then use the underlying enumerator. for (int i = 0; i < _length; i++) { yield return _original[i + _start]; } } IEnumerator IEnumerable.GetEnumerator() => GetEnumerator(); } ``` Here is a simpler example of an ```IString``` representing a single ```char```: ```C# using System; using System.Collections; using System.Collections.Generic; sealed class CharString : IString { private readonly char _ch; public CharString(char ch) { _ch = ch; } public char this[int index] { get { if (index != 0) throw new IndexOutOfRangeException(); return _ch; } } public int Length => 1; public IEnumerator GetEnumerator() { yield return _ch; } IEnumerator IEnumerable.GetEnumerator() => GetEnumerator(); } ``` And, finally, here's a wrapper over a char array: ```C# using System; using System.Collections; using System.Collections.Generic; sealed class CharArrayWrapper : IString { private readonly char[] _array; public CharArrayWrapper(char[] array) { _array = array; } public char this[int index] => _array[index]; public int Length => _array.Length; public IEnumerator GetEnumerator() => (IEnumerator)_array.GetEnumerator(); IEnumerator IEnumerable.GetEnumerator() => _array.GetEnumerator(); } ``` ### Comparison with ```IReadOnlyList``` There is an existing proposal, #14336, to add ```IReadOnlyList``` to the set of interfaces implemented by ```System.String```. While that would be a sufficient alternative, the big downside is that it's harder to type ```System.Collections.Generic.IReadOnlyList```. For code that consumes such strings, one could mitigate that with a using alias, but it doesn't help the public API surface area. Consumers probably already have a using statement for the System.Collections.Generic namespace, but it's still hard to discover, and not immediately obvious to the uninitiated, that ```IReadOnlyList``` is the _'I behave like a string'_ marker. I believe it's only a coincidence that ```IReadOnlyList``` has the exact shape required to be that marker. We'll Ignore, for now, the different ways of spelling 'Length'. ```IReadOnlyList``` has an advantage, though, because ```char[]``` already implements it. i.e. a ```char[]``` would also be a valid 'string-like' implementation without modification. That would _not_ be the case with ```System.IString```, hence the need for the CharArrayWrapper shown above. If we're willing to entertain _both_ proposals, then we could redefine ```System.IString``` as: ```C# namespace System { using System.Collections.Generic; interface IString : IReadOnlyList { } } ``` and accept the (mis-)spelling of 'Length' ;-) ### Limitations It's hard to come up with a concatenation implementation that performs well in all cases: Do you chain to the left, to the right, or try to keep the 'tree' balanced? However, for specific cases where you're building ""compound"" strings by concatenation, sometimes a special-purpose object will do. e.g. It's possible to create a custom ```IString``` implementation to represent a fully-qualified type name from its parts while avoiding allocating the final string. In some cases, it _is_ better to do eager string realization. For example, if you're going to do a lot of random access operations on an ```IString``` that is actually a complex, compound implementation (e.g. a concatenation of a bunch of substrings of a UTF8-encoded text buffer). Advanced library implementations would detect when to switch to a more efficient implementation (e.g. rebalance a tree, or decode the entire UTF8 buffer). For other cases, clients can always use the ```.ToString()``` escape hatch. Certainly, we assume that library authors will strive to make most situations no worse than using ```System.String``` directly. ### Future If ```System.IString``` is adopted, there are plenty of places in the Framework where we could/should provide new overloads for methods that currently take ```System.String```. e.g. Serialization, formatting, encoding, path building/parsing). Of course, none of the performance benefits will be realized if a consumer of an ```IString```-returning API immediately turns around and calls ```.ToString()``` on the result (perhaps in order to call another API which accepts only ```System.String```). Without broad library support, this proposal is likely to falter.

If someone calls `Current` twice, the selector will be evaluated twice. Repro: ```cs int selectorRuns = 0; var it = new[] { 0xff }.Select(i => selectorRuns++); using (var en = it.GetEnumerator()) { en.MoveNext(); // Before ran the selector, now doesn't int unused = en.Current; // Before didn't run the selector, now does unused = en.Current; // Now runs the selector again // Before, `selectorRuns` would be 1. Now, it's 2. } ``` **Why they're acceptable:** Enumerables are used mainly in two contexts: `foreach` and Linq. `foreach` handles this correctly by caching `Current` into a local at the beginning of the loop, so it can only be evaluated once. Linq handles things correctly and does not run `Current` more than once. Therefore, this change should break only fringe cases where 1) someone manually calls `GetEnumerator` on an enumerable and invokes `Current` more than once per `MoveNext` (a bug in their code) and 2) `e.Select` with an impure selector is passed to that function. **Performance results:** Not posted yet. I am wondering if maintainers think this is an acceptable change. I have marked this [No merge] temporarily because this is going to degrade perf in a few places where we check for `Iterator` for optimizations; [here](https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Select.cs#L25) is one of them.

Consider exposing a way to override it at runtime This is to follow up on a specific issue a customer created today on EF Core at https://github.com/aspnet/EntityFramework/issues/7283, but the problem has been brought to our attention before. Both EF6 and EF Core provide APIs that allow applications to create and initialize databases, check for their existence and modify their schemas. These operations can happen at design time (e.g. when using the migrations feature) or at runtime. **Attempting to connect to a database that doesn't exist is part of the normal flow of these operations.** In .NET Framework 4.5.1 SqlClient introduced a connection resiliency feature that performs automatic retries if failures occur during `SqlConnection.Open()`. Two new settings `ConnectRetryCount` and `ConnectRetryInterval` were added to the list of settings recognized in connection strings and a default behavior was adopted so if the first attempt to connect to a database fails a retry will occur after 10 seconds if these settings are not specified. The same feature is now included in the .NET Core version of SqlClient. With only the default behavior **this feature introduces a lag of 10 second for any calling code that attempts to connect to a database that doesn't exist.** It also prevents any calling code from implementing its own (potentially more efficient) retry logic correctly. This severely affects customer experience and can potentially affect runtime performance. Two main approaches have been proposed to mitigate this issue on EF code, but they have severe disadvantages: 1. Recommend customers to disable SqlClient's connection resiliency altogether by setting `ConnectRetryCount=0` when working EF and make sure the feature is disabled any time EF runtime or tooling creates a connection string, or even throw if an attempt is made to use a connection that has the feature enabled. The main disadvantages of this approach are: * It is not discoverable for customers and so users will still experience the 10 second lags (or exceptions if we decide to throw) for the default case. * It prevents the connection resiliency feature in SqlClient from being available in scenarios in which it could actually have been helpful. * EF6 supports older versions of .NET Framework than 4.5.1 and for those versions these settings are not valid. The logic would need to take the executing version of .NET Framework into account. 2. Store aside a copy of the original connection string so that we can modify it with `ConnectRetryCount = 0` and create a separate `SqlConnection` object to perform existence checks. * The main problem with this approach is that both EF Core and EF6 support passing a `SqlConnection` object to be used in the EF context. It is possible that the password would have already been removed from the `ConnectionString` in that connection object if it was open before, so in that case the connection string would not contain enough credentials to be able to create a separate functional connection object. At this point we believe that if `SqlConnection` exposed a way to programmatically disable connection retries **without requiring the modification of the connection string** we could modify EF6 and EF Core code to restore the correct behavior and eliminate 10 second lags. We are happy to discuss other options with the SqlClient team. Also note that this issue applies to both .NET Core and .NET Framework. cc @ajcvickers Note on how EF Core implements its own retry logic to check for database existence: In general, any code that is calling `SqlConnection.Open()` can leverage contextual knowledge to make connection retries more efficient. E.g.: - When EF Core performs existence checks, it will only retry on certain errors if they occur immediately after a database has been created. - For a regular existence checks (i.e. those that don't happen immediately after the database has been created) EF Core assumes that immediate failures coming from a database server mean that the database effectively doesn't exist and can avoid any retry logic. 14645 area-Infrastructure Release/1.1.0 versions fix Enable building with a uri version file so that we can pull versions from dotnet/versions for building tests against packages. 14646 area-Infrastructure Deprecate sync.cmd This is follow-up for https://github.com/dotnet/corefx/commit/2d3e555196bfa5c9d2156a9adcabf9ef902b1ba0.

In this change we are supporting the full OS encoding on Console and System.Diagnostics.Process without bringing the big encoding size cost (which is 600+ KB). The way we support it is we create an OSEncoding class wrapper which will call the OS instead of using our own encoding data. The only restriction we’ll have is cannot use encoding fallback with OSEncoding as this will be very slow and not intuitive. But this is acceptable as usually apps don’t use the console encodings for such fallback operation. But if anyone want to do that can still register the encoding provider and get full support. 14651 area-Serialization Potential Issues with Deserializing ISerializable Types "There's a couple of potential issues with deserializing ISerializable types, 1.

There are a couple of areas that need review: - [x] `SR` - [x] Added an overload to `GetResourceString` that doesn't require a default value (uses resource key as the default value). Not sure if this is the correct behaviour but the existing code does not use the second parameter. - [x] [Imported](https://github.com/tintoy/corefx/issues/1#issuecomment-268436631) messages from `System.Security.txt` into `Strings.resx`. There seem to be a lot of unused strings in here, not sure if you want them trimmed. - [x] `EncryptedXml` - [x] Merged the 2 non-default constructors (removing the overload that takes `Evidence` because as far as I can tell, there is no CAS in corefx). - [x] `SignedXml` - [x] Currently using a hard-coded constant for `szOID_KEY_USAGE` (`2.5.29.15`) because I can't find an existing constant to represent it. Let me know where you'd like this to live. - [x] Changed `X509Certificate2.GetAnyPublicKey` to `X509Certificate2.PublicKey.Key` because I can't find an equivalent method in corefx. - [x] Stubbed out `ReadAdditionalXXX` methods because there's no Registry to read from. - [x] `SymmetricKeyWrap` - [x] Suppressed code-analysis rule `CA5350` because the directive was to port the code as-is. - [x] `Utils` - [x] Removed references to `Registry`, substituting default values where they were previously read from the registry. - [x] Removed references to `[RegistryPermission]` because, as far as I can tell, CAS does not exist in corefx. - [x] Copied `HexEncode` / `HexDecode` methods from [X509Utils](https://referencesource.microsoft.com/#System.Security/system/security/cryptography/x509/x509utils.cs,6ef26ece8e08c36b,references) in netfx since there appear to be no public equivalents in corefx. - [x] `KeyInfoX509Data` - [x] Previously, `CryptographicException` was constructed with `CAPI.CERT_E_CHAINING` HRESULT constant. Linked `src/Interop/Common/src/Windows/Crypt32/Interop.certificates_types.cs` and used `Interop.Crypt32.CertChainPolicyErrors.CERT_E_CHAINING` since the associated message does not appear in the string resources. `System.Security.Cryptography.Xml.csproj` now builds correctly, but `System.Security.Cryptography.Xml.Tests.csproj` does not. This appears to be due to the steps taken to exclude it from the build. 14663 area-Infrastructure Add Configurations.props files for test projects, include tests in build.proj There were a large number of changes that needed to be made to the test projects and test code in order to get everything working in dev/eng. This gets all of the tests building and running against netcoreapp (minus one project). There is still no support for different targeting packs (`netstandard1.3`, etc.), so everything is still compiling against the netcoreapp targeting pack (built live). Issues remaining: * There are some workarounds necessary because of the `TypeInfo` inheritance issue ( #14334 ). These are present in the tests for System.Runtime, System.Linq.Expressions, and System.Reflection.Emit. * System.IO.IsolatedStorage is failing sometimes on my machine; no idea why. It usually succeeds when re-tried. I get `UnauthorizedAccessException`s when it fails. * System.Security.AccessControl.Tests always fails for me because of a debug assertion in the product code. No idea why yet, so I disabled the test project. * System.Linq.Expressions references the source project because it uses types not exposed in the contract. This is happening in master, too, so it's not a change from before. @joperezr @weshaggard @ericstj @karajas 14665 area-Infrastructure Clean up build-native.cmd/sh A couple of improvements suggested by @weshaggard and @ericstj . 14666 area-Infrastructure Update BuildTools Version Pick up revved build tools version using UtcNow instead of regular Now for build version. @chcosta @joperezr @markwilkie 14667 area-Infrastructure Update to buildtools version 1.0.25-prerelease-01121-03 14669 area-Infrastructure Cleanup TargetingPackReferences from dev/eng "It looks like we're still using ""TargetingPackReference"" even though reference seems to be all that's needed.

This is causing the build to take a very long time compared to Windows. My 8-core Ubuntu machine has only one core being utilized during the ref build, even though there are tons of MSBuild processes active. It looks like the src build is handling this a bit better (faster and more CPU utilization), but I'm not sure it's as good as Windows there either. It still seems slower to me.

The value of the Version attribute, a decimal integer, identifies the version of the state management specification to which the cookie conforms. For this specification, Version=1 applies. In the msdn documentation for [Cookie.Version](https://msdn.microsoft.com/en-us/library/system.net.cookie.version(v=vs.110).aspx), it states > The default value for the Version property is 0, complying with the original Netscape specification. If the value is explicitly set to 1, then this Cookie must conform to RFC 2109. RFC 2109 was obsoleted by RFC 2965 so as per the newer spec, specifying Version=1 means RFC 2965 applies. RFC 2109 requires a specified domain to be have a leading dot whereas RFC 2965 does not require this. When making a request using HttpClient to an HTTP server which returns a cookie with an explicit domain without a leading dot and specifying version=1, the cookie is dropped. Here is some simple code reproducing the issue. ```csharp var mycookie = ""lang=en-US; Domain=example.com;Path=/;version=1""; var uri = new Uri(""http://example.com""); CookieContainer container = new CookieContainer(); container.SetCookies(uri, mycookie); ``` This throws a CookieException when the cookie is valid. The cookie parsing code in HttpClient swallows this exception. RFC 2965 is further obsoleted by RFC 6265 which makes no mention of the Version attribute but does say that there is no need for a leading dot, and if it is there, to strip it out and ignore it. So either the latest RFC should apply in which case the example cookie I provided should parse, or the latest RFC which claims it should apply which mentions the Version attribute should apply." 14675 area-System.Linq Reduce allocations in {Concat,SelectMany,Append,Prepend}.ToArray by close to 50% **Background:** Some `ToArray` implementations employ a double-buffering strategy if we don't know the exact length of the output array. First the items are copied into some sort of buffer, then they are transferred into an array. For example, in the following snippet ```c# var array = new[] { -1, -2, -3 }; Enumerable.Range(1, 100).Concat(array.Where(i => true)).ToArray(); ``` In `ToArray`, we know the size of the lhs enumerable but not how many elements are in the rhs one. So we allocate a buffer with 100+ elements to hold everything, calculate the final size of the array, and re-copy those elements. ```c# Buffer: [1 2 3 .. 100 -1 -2 -3 0 0 .. 0] Array: [1 2 3 .. 100 -1 -2 -3] ``` **Description:** Instead of copying everything twice, we can buffer only the enumerables we can't get the count of. If we reach an `ICollection` or an `IIListProvider` and it has N items, we queue it to be copied later, and tell the builder to leave a gap of N items in the output array. Finally, when `ToArray` is called, we revisit all of those queued collections and copy them directly to the output. Here is how the above example works now: ```c# // Stage 1: First pass Buffer: [-1 -2 -3 0 .. 0] Markers: [(Index: 0, Count: 100)] // During ToArray(), leave a gap of 100 items at index 0 QueuedCollections: [Enumerable.Range(1, 100)] // Stage 2: Call ToArray() Array: [0 0 0 .. 0 -1 -2 -3] // The first 100 slots are empty. // Stage 3: Loop thru each of the indices in Markers and copy the corresponding // queued collection to that index. Array: [1 2 3 ... 100 -1 -2 -3] ``` **Performance results:** An initial test is showing almost 50% decrease in GCs in `SelectMany(e => e).ToArray()`, assuming `e` is always an `ICollection`. [results](https://gist.github.com/jamesqo/9b1fc0a5d59fe41fd34974ad249693a9) / [test](https://github.com/jamesqo/Dotnet/blob/d64997ccef2ceec8b2903cf94ddba01e349e780b/Program.cs) **Methods this affects:** `Concat().ToArray()`, `SelectMany().ToArray()`, `Append/Prepend().ToArray()` I had to pull in the changes from https://github.com/dotnet/corefx/pull/13942 because this affects `SelectMany`, so the LOC in the diffs is exaggerated.

Turning off ErrorAndContinue for serialized projects.

Regardless, I think this may only be part of the problem, I also think that the target ordering changes I've done may be causing MSBuildLastTaskResult to not be properly set which is hiding failures).

So on my branch on corefx, I have started to update `AssemblyLoadContext.cs` with this new API. But it seems that `BUILDTOOLS_OVERRIDE_RUNTIME` is not taken when performing an APICompat with the API. We should be able to easily build corefx with a local coreclr and make changes to the ref API to use the new API introduced by the local coreclr. 14733 area-System.Runtime Add test for order of raising AssemblyLoadContext.Unloading and AppDo… …main.ProcessExit coreclr PR: https://github.com/dotnet/coreclr/pull/8737 14735 area-Infrastructure Need the instruction about how to integrate corefx changes with my application.

I initially chose this limit to be 32 elements, because I didn't want it to be too small in case `sizeof(T)` was small, but also didn't want it to be too large in case `sizeof(T)` was large. **Description:** Since writing https://github.com/dotnet/corefx/pull/14020, I've come to realize that the 90% use case for Linq is with business objects / classes, and not with low-level stuff like bytes. Since reference types are 4/8 bytes wide, it makes sense to optimize for `T` being wider. This PR lowers the resize limit of `LargeArrayBuilder` from 32 -> 8 elements. **Performance improvements:** [gist](https://gist.github.com/jamesqo/641ab9dc63f5abcade39cd7453106afa) For reference types, there is a decrease of ~5 GCs for sizes 9-15, and ~10 GCs from 17-31 and 33+. Sizes 16 and 32 regress, which is expected since the array is now chunked at those sizes and the builder can't directly return it. cc @stephentoub, @JonHanna, @VSadov " 14739 area-System.Text Change expected behavior for reported parameter names.

Regardless of exceptions, all callbacks are still invoked. The desired behavior is that exceptions are not caught. `AppDomain.ProcessExit` and `AssemblyLoadContext.Unloading` are typically raised from the finalizer thread, so an unhandled exception from any handler is expected to crash the process. 14748 area-System.ComponentModel RequiredAttribute ErrorMessage and DefaultErrorMessage null by default The `ErrorMessage` and `DefaultErrorMessage` properties are used by `ValidationAttributeAdapter.GetErrorMessage` to obtain the localized error message.

Some where about alternate design decisions. Most about limiting counts which would be a breaking change now. - General cleanup. In adding the tests I found that GenericIdentity can not be used with BinarySerializer. Any ClaimsIdentity with a Claim will throw and GenericIdentity always adds 1 claim.

There are still a few TODOs floating around, but feel free to review. **Changes:** - Theorize most of the tests to make it easier to add new test cases - Segregate tests that assert equality from tests that check exceptions - Standardize method/variable naming to make tests easier to read - Fill in some gaps in the tests - Test more explicit interface implementations - Run methods that accept comparers over a variety of comparers - Run methods that accept collections over a variety of collections (arrays, lists, `IList`, lazy enumerables, etc.) - General cleanup - Replace `Assert.Equal(immutableArray1, immutableArray2)` with `Assert.True(immutableArray1 == immutableArray2)` - This has a poorer stack trace, but it makes it more explicit that we're testing reference equality **Note:** I tried to keep many of the existing test cases we have, so that's why you'll see a lot of (sometimes redundant) cases in the MemberData. /cc @AArnott @ianhays @stephentoub 14803 area-Infrastructure Use armel instead of arm-softfp Signed-off-by: chunseoklee 14804 area-Infrastructure Test failure: CancelKeyPressTests/CanAddAndRemoveHandler_Remote Opened on behalf of @jiangzeng The test `CancelKeyPressTests/CanAddAndRemoveHandler_Remote` has failed.

(2) Providing some locking and identity capture functionality, none of which is used in System.Net.Sockets.

We still want to override it, but the implementation needs more thought. Second commit fixes #14698. In .NET Core 1.x, SslStream's usage of Begin/EndRead/Write was actually using extension methods that just used TaskToApm.Begin/End with Read/WriteAsync. When the base Stream's Begin/EndRead/Write methods were added back, SslStream's usage of these methods started binding to the base methods, such that it was no longer using the inner stream's Read/WriteAsync. This change explicitly switches all of those calls (for both SslStream and NegotiateStream) to use Read/WriteAsync. A better solution is to actually add SslStream.Read/WriteAsync overrides that use async/await and tasks all the way down, rather than going back and forth between Tasks and APM, but that is a more complicated work item. This addressesses the immediate need (problems related to deadlocks on SslStream when read and writes are issued to run concurrently on the same stream) and can be undone or augmented subsequently when a better solution is available. This is at least as good performance-wise as what we had in .NET Core 1.x, and in some cases is a bit better, as we can avoid creating the IAsyncResult wrapper in some cases if the returned task is already completed. cc: @cipop, @benaadams, @cesarbs 14853 area-System.IO Idea: switch to libzip for ZIP archive implementation By way of introduction, I work on the Xamarin/Mono team at Microsoft (Xamarin.Android and, from time to time, a foray to the Mono BCL/runtime land) and we've been struggling with various issues related to ZIP archive support over the past few years. The main problem with all (as far as we can tell) managed implementations is that they implement only a subset of what's supported by the ZIP format and ignore parts that are important on non-Windows systems (especially all flavors of Unix). The biggest issue is lack of support for the extended Unix fields (described in the [PKWARE appnote](https://pkware.cachefly.net/webdocs/APPNOTE/APPNOTE-6.3.3.TXT) as well as in [this document](https://github.com/grendello/LibZipSharp/blob/master/docs/extrafld.txt). Support for those fields is important because they make difference between special files and regular files as stored in the archive (that includes file permission bits on Unix). Another issue (less common but still occasionally relevant) is lack of support for symbolic links in managed libraries. Yet another problem is an occasional issue with even opening some ZIP archives (especially created with older versions of ZIP and friends) to the point that we had to resort to using the external `unzip` program to open some archives. For the record, the minimum set of extended fields that would need to be implemented is: `0x000d`, `0x5855`, `0x6375`, `0x7855`, `0x7875`, `0x5455` and symbolic links (which are stored as special files in the ZIP archive) To address those problems we decided to implement our own support for the ZIP archive and after looking around we chose [libzip](http://hg.nih.at/libzip/) as the base for our code. The library implements support for ZIP archive **format** while deferring (de)compression to the venerable zlib library (the same one corefx uses). libzip is cross-platform, works very well on both Unix and Windows systems, is (IMO) very well written and maintained, and uses a [permissive license](https://nih.at/libzip/LICENSE.html). It does **not** implement support for interpreting of the extended fields, merely supports writing/reading them as blobs of binary data. For that reason we created a [managed wrapper](https://github.com/grendello/LibZipSharp) around libzip which not only provides and object-oriented implementation of the libzip APIs but also implements support for the most important extended fields, as listed above. We've been using both libzip and libzipsharp in Xamarin.Android for a while now and found them to work without any issues. I think it would be great if corefx implemented full, cross-platform, support for ZIP archives and while it could be done in-house I think supporting (by using and contributing to) libzip is would be the best way to go, since many projects would benefit from a single, solid implementation of the ZIP archive format. 14855 area-System.Xml Many XML tests are outerloop... why?

But there is still native components like `clrcompression.dll` that imports `api-ms-win-crt-runtime-l1-1-0.dll` and `api-ms-win-crt-heap-l1-1-0.dll`, making corefx dependent on an installed C runtime just for a few functions imported... This lead to problems like [""dll missing from your computer""](https://github.com/dotnet/cli/issues/5201) which is also [infamously popular for many other applications](https://www.google.com/search?q=missing+api-ms-win-crt-runtime-l1-1-0.dll) These native dlls are probably the last dlls in a repo that have a dependency to the CRT... removing these dependencies would make a self contained dotnetcore app runnable almost on any Windows OS.

Before this change, it essentially always has the exact same value as `$(OS)`. We have some logic in dir.props that is supposed to normalize the values to Windows/Unix, but .NET Core MSBuild already does that by default, so we aren't actually doing anything useful there anymore. This change makes dir.props default `$(OSEnvironment)` to a value representing one of our actual OSGroups: Windows_NT, Linux, or OSX. Places expecting ""Unix"" have been changed to just use `$(OS)`. We differentiate between Linux and OSX by checking for the existence of an OSX-specific folder. This allows you to simply run `msbuild /t:rebuildandtest ` and have it work, without needing to pass `/p:OSGroup=Linux/OSX` manually. @joperezr @weshaggard Roslyn.Common.props is unchanged except `$(OSEnvironment)` has been changed to `$(OS)`." 14868 area-Infrastructure AssemblyInfo for ref assemblies should not use AllowPartiallyTrustedCallersAttribute "While working on adding ref assemblies for `System.ValueTuple` (PR https://github.com/dotnet/corefx/pull/14786) I ran into this problem with the `portable-net40+sl4+win8+wp8` TargetGroup (which uses a PCL profile).

In an effort to reduce heap allocations, it would be good if implementing providers could have a way of checking whether there are subscribers or not before allocating and calling `DbConnection.OnStateChange`. # Proposal Add a protected, non-virtual method called `StateChangeHasSubscribers` to `DbConnection`, returning a bool.

This happens when we open a large number of simultaneous connections to Kestrel. What I've discovered so far is that `SslStream.AuthenticateAsServerAsync` is taking significantly longer to run. Opening 256 connections and measuring the time that takes to run in Kestrel 1.1.0 (which referenced CoreFX 4.3) I get an average of 339 ms per call. Running against our dev branch (referencing CoreFX 4.4 packages), I'm seeing an average of 10 **seconds** per call, and some of the tasks never appear to complete in a reasonable time. The delay appears to be proportional to the number of simultaneous calls we're making. Here are some rough measurements of the average time to authenticate depending on the number of simultaneous connections we open against Kestrel: Connections | Time -------------- | ------ 1 | 56 ms 2 | 65 ms 4 | 66 ms 8 | 76 ms 10 | 132 ms 12 | ~1 **s** 16 | ~4.5 **s** 32 | ~10 **s** _not all tasks complete_ 64 | ~10 **s** _not all tasks complete_ 128 | ~10 **s** _not all tasks complete_ 256 | ~10 **s** _not all tasks complete_ I wrote a small program to measure this more isolatedly: https://gist.github.com/cesarbs/4409b712351adf621aae8420e1ea33de On CoreFX 4.3 the call to `AuthenticateAsServerAsync` takes about 38 ms on average. On 4.4 that average is 99 ms (a discrepancy with Kestrel that I can't explain). Another interesting thing about this is that I only see those figures in the first request to the program - subsequent requests take around 3 ms to authenticate on both CoreFX versions. cc @mikeharder 14960 area-System.Data SQL Tests: Refactoring tests and adding auto execution for Diagnostics test The Diagnostics tests in System.Data.SqlClient were meant for manual execution.

The results for `InsertRange` and `AddRange` are less dramatic, but still consistently positive.

Note that we haven't performed any measurements to try to understand the impact of this change and that the higher level components we work on such as EF6 and EF Core currently would not take advantage of it, but we are creating this issue mainly to give the SqlClient team a chance to evaluate this improvement for other code that uses this ADO.NET API directly. Also note that fine-grained async APIs that return `Task` (such as `ReadAsync()` and `IsDBNullAsync()`) are better off returning cached `Task` instances to gain efficiency instead of adopting `ValueTask`. From my perspective, there are a couple of open issues if we decided to do this: 1. Naming of the new method: since there can't be yet another overload that only differs on the return type, and the ""standard"" name with just the `Async` suffix is taken. 2. Compatibility for providers: It seems desirable to offer a default implementation of the Task-based method that calls `AsTask()` on the `ValueTask` instance returned by the new API, so that new providers don't need to implement the old `Task` version of the API but instead only implement the more efficient `ValueTask` version. It also seems good not to force existing providers to switch. I am currently thinking that adding an optional interface with the new API could be a solution, but there are other disadvantages in that approach. cc @stephentoub @YoungGah @saurabh500 " 15012 area-System.Net Consider making NegotiateStreamPal and related APIs in Common a reusable component System.Data.SqlClient needs to use the GSSAPIs to interact with the Kerberos tokens to authenticate Sql Server users on .Net Core on Linux and macOS System.Net.Mail has a dependency on the Interop Classes in Common folder, e.g. https://github.com/dotnet/corefx/blob/fd15ab1de03a4431e0ead9ff10e1bf53e2ae4bb7/src/System.Net.Mail/src/System.Net.Mail.csproj#L148 Can the Common\System\Net\Security\* and related files be made a component (a Nuget package) which can be reused by SqlClient, System.Net.Security and System.Net.Mail? This will allow the consumers to consume a single package instead of including the platform specific files for compilation in the project files. Alternatively, can APIs be added to interact with GSS-APIs using .Net Core so that the managed version of System.Data.SqlClient be truly portable without taking platform specific dependencies?

To do this we need incoming requests to be tagged with an ID (and potentially other information), and have this information 'flow' through (be available) to all code run in response to that request and in particular allow this information to be propagated to any outgoing requests. This class is meant to effectively augment existing DiagnosticSource telemetry, and be compatible/leveragable from using the existing ILogger and EventSource based logging as well. The result is that all these logging mechanisms will now have 'end-to-end' event correlation (every event has an activity, and for any event you can find the chain of activities that 'caused' it). # Concepts The main new code is the Activity class. Conceptually an Activity is something that starts and stops (thus it has a start time and duration), and potentially has a 'Parent' that 'caused' it. In addition it has two sets of arbitrary key-value pairs. The first is called 'Tags', which are intended to be logged with the activity but do NOT propagate to children. The second is 'Baggage' that DOES propagate to children. Tags are intended to augment telemetry, baggage is intended to control telemetry. # Usage scenario: Modify existing Incoming HTTP Request telemetry code (e.g. in ASPNet.Hosting) to - Extract data (e.g. an ID) from the HTTP header - Create a new a new Activity which has this ID as a parent and stores any other telemetry data values from HTTP header. - Make the activity current with the Activity.Current and log the telemetry with the DiagnosticSource.Start() API. - Now at any point, the telemetry context is available in Activity.Current. Modify the existing Outgoing HTTP request telemetry (e.g. in System.Net.Http) to - Looks at Activity.Current and injects the current ActivityID and Baggage into the outgoing HTTP header. This feature is focused on context itself and does not cover incoming/outgoing operations handling (they are in different DLLs and will be covered in subsequent pull requests). The API is inspired by [opentracing.io](http://opentracing.io/) standard ([API specification](https://github.com/opentracing/specification/blob/master/specification.md)) and implements following concepts: # Proposed API ```c# namespace System.Diagnostics { public class Activity { //name of operation public string OperationName { get; } //id of the activity. Propagated to dependencies, so parent-child relationship of activities could be logged public string Id { get; private set; } // activity start timestamp public DateTime StartTimeUtc { get; private set; } //duration for stopped activity public TimeSpan Duration { get; private set; } //reference to parent activity if any; public Activity Parent { get; private set; } //represents Id of parent activity, may be passed from external service public string ParentId { get; private set; } // list of key-value pairs which may be used for logging. E.g. HTTP Method and Path. Users can enumerate tags and add new tags public IEnumerable> Tags {get;} //list of key value pairs to be propagated to downstream services. E.g. correlation-id. Users can enumerate baggage, request baggage by name and add new items public IEnumerable> Baggage {get;} //Current Activity for the current thread. This flows across async calls. public static Activity Current; public Activity(string operationName); public Activity AddTag(string key, object value); public Activity AddBaggage(string key, string value); public Activity SetParentId(string parentId); public Activity SetStartTime(DateTime startTimeUtc); public Activity SetEndTime(DateTime endTimeUtc); public string GetBaggageItem(string key); //Sets activity parent and Activity.Current public Activity Start(); //Restores Activity.Current to parent activity public void Stop(); } // wrapper methods in DiagnosticSource for activity Start and Stop which writes corresponding events to DiagnosticSource public abstract partial class DiagnosticSource // in addition to existing methods { public Activity StartActivity(Activity activity, object args); public void StopActivity(Activity activity, object args); } } ``` # Usage Sample ```c# namespace App { public void OnIncomingRequest(DiagnosticListener httpListener, HttpRequest request) { // This code represents code in say web service's hosting layer that receives an // Incoming HTTP from outside the process. We expect to instrument this code // to accomplish the following three things // 1) Create a new activity that will track through the system as the request is processed // 2) Look for items in the HTTP request that can be used to correlate this incoming // request with other processing on other machines. These should be put into // the newly created Activity so it is available for all subsequent logging. // 3) Log the start and stop of this activity that was created. // // In this example we look for the 'x-ms-request-id' as a HTTP header that identifies // a ID unique ID and passes along any values with the 'x-ms-baggage' prefix. // if (httpListener.IsEnabled(""Http_In"")) { var activity = new Activity(""Http_In""); //parse request headers and add tags and baggage activity.SetParentId(request.headers[""x-ms-request-id""]) foreach (var header in context.Request.Headers) if (header.Key.StartsWith(""x-ms-baggage-"") activity.AddBaggage(header.Key, header.Value); //start activity httpListener.StartActivity(activity, context); try { //process request ... } finally { //stop activity httpListener.StopActivity(activity, context); } } } public void OnOutgoingRequest(DiagnosticListener httpListener, HttpRequestMessage request) { // This code represents code in the framework where an outgoing HttpRequest is being // sent to another machine. The goal of this code is to create and log an activity associated // with doing this as well as to add the ID and any Activity Baggage to the outgoing HTTP // header. if (listener.IsEnabled(""Http_Out"")) { var activity = new Activity(""Http_Out""); //start new activity, Parent for this activity is assigned to Activity.Current listener.StartActivity(activity, new { Request=request) }); try { // Attach our ID and Baggage to the outgoing Http Request request.Headers.Add(""x-ms-request-id"", activity.Id); foreach (var baggage in activity.Baggage) request.Headers.Add(baggage.Key, baggage.Value); // Actually perform the Http Write Request, get the response } finally { listener.StopActivity(activity, {new { Response=reponse }); } } } public void Startup() { // This is code that shows usage to get at the logging (and activity) information // logged by the code above. This follows normal DiagnosticListener conventions. // In which you subscribe to and new DiagnosticListener. // (We assume the DiagnosticListener we used above is called 'System.Net.Http') // From there we can subscribe to its events. // Events will be fired on every Start() and Stop() call above, and the Activity.Current // will be accurate during those callbacks. Thus you have all the information passed int // the Start() or Stop() call as well as all information from Activity.Current available // in the callback. DiagnosticListener.AllListeners.Subscribe(delegate (DiagnosticListener listener) { if (listener.Name == ""System.Net.Http"") { listener.Subscribe(delegate (KeyValuePair value) { // In this demo we simply log to the console what things are happening. Console.WriteLine(""Event: {0} Current Operation: {1} Current ID {2}"", value.Key, {Activity.Current.OperationName}, {Activity.Current.Id}); }); } } } } ``` # Notes We want to bring Activity to ASP.NET 4.5 and ASP.NET Core users which require DiagnosticSource for NET 4.5.

Here is a summary: 1) The original .NET Framework (Desktop) code for the HttpClientHandler implementation has been ported for this net46 build. It replaces the WinHttpHandler based code that is used for the other builds of .NET Core (Windows). This means that it uses the original HttpWebRequest (HWR) code in .NET Framework System.dll which is based on managed sockets. This ensures we go back to 100% app-compat behavior against .NET Framework. This also means that existing code that uses ServicePointManager to control behavior will also work 100% app-compat. One downside of this PR is that HTTP/2 protocol support is no longer available since we are reverting back to original .NET HTTP stack for the net46 build. If HTTP/2 protocol support is required on .NET Framework (Desktop), then a developer can use the separate WinHttpHandler package to get that. 2) The System.Net.Http.dll assembly is now marked as APTCA (Allow Partially Trusted Callers) similar to the original annotation of the .NET Framework version of the assembly. As part of this, a few security annotations were added to source code that is being compiled from the CoreFx repo. The SecAnnotate tool was used to verify the annotations and the tool now runs clean against this assembly. 3) This PR also addresses the problem introduced where .NET Framework WebRequestHandler wasn't compatible with the OOB System.Net.Http.dll on Desktop. I manually tested packages with this change and verified sending an HTTP request. There is no longer any ""Derived types must either match the security accessibility of the base type or be less accessible"" exceptions. 4) The tracing mechanism of this implementation implicitly re-activates the System.Net tracing (TraceListener based) since we are now going back to the original .NET Framework HTTP stack. However, part of the source code for the rest of the assembly compiled in from .NET Core repo also includes the new DiagnosticSource tracing as well. There didn't appear to be any negative consequences of leaving this in as it simply adds extra tracing on top of the original System.Net tracing. 5) There are 8 new properties that were added to the HttpClientHandler class compared to the original HttpClientHandler defined in .NET Framework. These new properties are part of the NETStandardard2.0 definitions. Due to switching back to the original HTTP stack implementation in Desktop, some of these new properties can not be implemented fully since there are incompatibilities between defining them as per handler instance compared to the actual underlying ServicePointManager implementation. So, some of these properties will throw PlatformNotSupportedException for now. Since these were newly added properties, the expectation is that there will be minimal app-compat affect. 6) Even with this PR, any project using an OOB (Out of Band) assembly such as System.Net.Http.dll might be REQUIRED to have binding redirects in their app.config/web.config. This is because there needs to be a way to reconcile onto ONE assembly version of the same name. In particular implicit and explicit references to something like the .NET Framework System.Net.Http.WebRequest.dll (which contains WebRequestHandler) is bound to the System.Net.Http.dll version 4.0.0.0 of the .NET Framework. Once an OOB System.Net.Http.dll is introduced, there is now another version of System.Net.Http.dll with a different version number. For the current master branch, the System.Net.Http.dll assembly version is 4.2.0.0. Note that the assembly version is disjoint from the NuGet package version (currently at 4.4* in the master branch). So, this requires a binding redirect in the app.config/web.config similar to: ```c# ``` Tooling such as Visual Studio will normally create this binding for you. But we have seen cases where it doesn't do it automatically. Please keep this in mind. If you don't have any binding redirects for System.Net.Http.dll, you will potentially get errors when sending an HTTP request such as this: >System.InvalidCastException: [A]System.Net.Http.Headers.MediaTypeHeaderValue cannot be cast to [B]System.Net.Http.Headers.MediaTypeHeaderValue.

This is very useful for certain type of applications where the curve is a configurable option (for example, a German company that insists on using brainpool curves for certain operations). What we don't have right now is an easy way to list all of the supported named curves for a particular platform. Keeping with the brainpool example, Windows 10 supports most (if not all) of the named brainpool curves, however Windows 8.1 and below do not in CNG. Also, depending on how far #9394 goes, macOS CommonCrypto / Security Transforms do not support curves other than the standard NIST prime curves and some of djb's curves. I'm not entirely sure all platforms support arbitrary curves, either (for example, Twisted Edwards curves). I would then propose an API that lets us determine the capabilities of the current platform. 15072 area-System.Security Fix Windows 7 issue with RC2 EffectiveKeyLength "The SymmetricAlgorithm RC2 is broken with Windows 7; this fixes that by setting EffectiveKeyLength on the algorithm handle instead of the key handle.

While tracking down some odd behaviour with HttpClient on OSX (request body always seems to be buffered, unlike response body) I noticed that `CurlHandler` calls `HttpContent.ReadAsStreamAsync` rather than `CopyToAsync`: https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/Unix/CurlHandler.MultiAgent.cs#L1167 Am I correct in my assumption that this means the request body will always be buffered before sending? From what I understand, `CopyToAsync` will copy the stream without buffering if possible, but `ReadAsStreamAsync` will load the stream into a buffer first and return a stream over that buffer. Looking at the code I can see why it's been done that way but it means that, unlike the Windows implementation, uploads of really large files may cause problems. 15098 area-System.IO Paths with bad colons don't throw ArgumentException On desktop paths like `C::` would throw `ArgumentException`.

This means that for a portable app using the shared framework it may see copy-local assets from 1.0/1.1 without seeing any of the newer 2.0 SharedFramework assets to cancel them out. 1. One solution is to make NETCore.App carry metadata (via a generated props file) that lists all the runtime files it represents. These can be fed into conflict resolution as an independent item. 2. Another solution would be to make MSBuild aware of the contents of the shared framework directly and use these for conflict resolution. I'm thinking to do 1 since it doesn't involve ""searching"" for the shared framework. @eerhardt did you do something similar in publish? How are you handling filtering now that type/platform doesn't exist.

Re-issue of https://github.com/dotnet/cli/issues/4227 # Problem The following problem occurs when attempting to build a dotnet project in Ubuntu when the project to build is located on a network file system. When I run `dotnet build -f netstandard1.6` on any project, `dotnet build` returns the following output: ``` Project projectname (.NETStandard,Version=v1.6) will be compiled because expected outputs are missing Compiling projectname for .NETStandard,Version=v1.6 Access to the path '/mnt/users/username/Documents/Source/projectsolution/src/projectname/obj/Debug/netstandard1.6/.SDKVersion' is denied. ``` However, when I run `ls -lah` with the path shown above, it shows me that the file is accessible (at least for me): ``` -rwxr--r-- 1 username usergroup 0 sep. 22 11:31 /mnt/users/username/Documents/Source/projectsolution/src/projectname/obj/Debug/netstandard1.6/.SDKVersion* ``` I am also able to open, edit and delete the file in the file explorer, with `gedit`, with `vim` or other usual tools. Running `chmod a+rwx` on the file, so that all access right are granted does also not solve the problem. In this case the project files are located on a NFS file system that is mounted in ubuntu.

The time has finally come to get these changes into master so we are going to use this issue to give a heads up on the details. ## Primary reasons for the changes * **Build from source** * Value: Simplify on-boarding of new Linux distros * As we have worked more in the open source space we finally made the realization that the source itself is also a product and we need to enable others to easily consume and build our full product from the source code itself. Our engineering system had numerous problems that made it difficult to bootstrap and build a full product from source with minimal external dependencies. * **Package reduction** * Value: .NET Core is now 1 package instead of 100's of tiny packages * We realized that we went overboard with the number of individual library packages we have. While it enables a very flexible system it also greatly increases the complexity of composing a fully functional framework. * **Other changes** * Build produces flat product layout which is ready for execution * Better build defaults (use your environment) ## When are we merging We are planning to begin merging changes on Friday 1/13 and to help with the merge conflicts we plan to **disable commits/merges** to corefx master branch on **Friday 1/13, Sat, Sun, and Mon 1/16**. We will open up the master branch again as soon as we have the merge in and the master branch functional. After the merge any active PRs will need to be rebased on top of master. Fri 1/13 **merge** is in https://github.com/dotnet/corefx/pull/15165. The branch is unlocked now. ## What does it mean to folks working in corefx After pulling the merged changes you should do a full clean and build. ``` clean --all build build-tests ``` As part of this work we have split the build and build-tests into separate steps, and build will only build the product and build-tests will build and run the tests. We highly recommend reading over our developer guide to better understand the developer workflow https://github.com/dotnet/corefx/blob/dev/eng/Documentation/project-docs/developer-guide.md. Given with the way we are building now you need to build from the root at least once before you can work on an individual project, from the command line or in VS. ## What changed Before we would multiplex our build configurations at every individual library level (i.e. .builds files) and in order to do that it required that we had a previous version of lots of the CoreFx libraries which we retrieved by restoring nuget packages of a previous corefx official build. That caused a lot of extra complexity in numerous ways such as restoring tons of nuget packages on every build as well as building for all configurations all the time. With our engineering work we have eliminated a lot of those complexities. Now the only nuget packages are for things that don't build in corefx itself and the package restoring will be scoped to tool initialization and under the external directory. All dependencies that are part of corefx will be **built live** in corefx instead of being restored from older packages. Now when you build from the root we will build all the reference assemblies and create a targeting pack in a flat directory and then build all the libraries referencing things from the targeting pack. By default this will produce a .NET Core build for the OS you are running on and it will create a flat runtime directory `bin\runtime\netcoreapp--Debug-x64` which will contain a fully runnable framework. That runtime directory can be used to run a .NET Core application via corerun or dotnet hosts. So no more groveling through the bin directory to try and cobble together a functional framework. The tests will also build against this targeting pack and then run on the flat runtime directory that was produced. This also means no more copying or hard-linking the entire framework into every test output directory. We believe these changes will make working in corefx a ton easier. However, it does add a little more work – you need to do root level build to setup the targeting pack and runtime before you can work on libraries. Moreover, if you want to work on more than one framework/configuration (.NET Core, desktop/netfx, and uap), you will need to do a root level build for each of the frameworks/configurations. Root level builds will only build the configuration that is specified so it will skip libraries that aren't applicable to that configuration. We have replaced the .builds files at the library level with a configuration.props file. The configuration.props file will list out the set of supported configurations and when building we will pick and build the best configuration and skip it if there isn't a valid configuration for what you are building. For more details on the configurations see https://github.com/dotnet/corefx/blob/dev/eng/Documentation/coding-guidelines/project-guidelines.md. Another part of the changes is in support of the package reduction goal. We now build a single package that contains all corefx libraries that are part of .NET Standard 2.0. This means that we will be deleting a lot of low level individual library packages and instead our root .NET Core package will contain all those libraries in the one package. This will greatly reduce the number of packages we produce and reduce the package graph depth and complexity for .NET Core applications. We hope this will remove the need for a degree in combinatorics and graph theory to be a .NET Core developer :). ## Things left to be done While we believe we got the basic .NET Core stack functional there are still a number issues that need to be addressed. We have tagged related issues with dev-eng and you can see the current backlog at https://github.com/dotnet/corefx/issues?q=is%3Aissue+is%3Aopen+label%3Adev-eng. A few of the more notable ones are: 1. Desktop/Netfx build configuration and tests aren't functional https://github.com/dotnet/corefx/issues/14911 (ETA: 1-2 weeks) 2. UWP build configuration and tests aren't functional https://github.com/dotnet/corefx/issues/14592 (ETA: 2-3 weeks) We hope that these changes will make working in corefx a lot better but please don't hesitate to let us know any issues you run into and we will do our best to address them. 15136 area-Infrastructure Cannot run tests against specific desktop TFMs You can specify a [particular config file](https://github.com/xunit/xunit/blob/master/src/xunit.console/CommandLine.cs#L116) with the xunit console runner.

The precondition is, that I'm sitting in a cooperate network with some kind of proxy/firewall - combination dropping all traffic not routed through it. Authentication method is Windows/NTLM (i guess..?). I cloned the repository yesterday and tried to build it but did not get far with that. In my opinion there are (as far as I can tell) two sources leading to a similar problem: 1) While executing `init-tools` for the first time i ran into proxy issues while downloading the .zip-file containing the current CLI/dotnet.exe. I could work around this by enriching the download-call in the `init-tools.cmd `- file with some proxy-parameter-love. 2) Later in the build process when calling `build-managed`, the target ""VerifyDependencies"" from Tools/Microsoft.DotNet.Build.Tasks.dll (called from VersionTools.targets) uses a WebClient without any proxy parameters. Result is a System.Net.WebException ""(407) Proxy authentication required"". `build-native `worked fine btw!

My guess of the failure was a timing thing because I was setting `DisableCaching` to `true` on `TestData`, so probably a test that didn't referenced `TestData` but did needed a switch value got it before caching was disable and that caused the failure. So I changed the approach to have a base class where all the tests in `System.Xml.XmlSchemaSet.Tests` inherit and on a static constructor disable caching so that we ensure that no matter what is the tests' timing or execution order `DisableCaching` is set to true from the beginning. Will run CI tests multiple times before merging to make sure it passes multiple times and we should leave this tests enabled at least one day if they fail again to see if the failure is consistent. /cc @sepidehMS @AlexGhiondea @danmosemsft 15170 area-Infrastructure Symbol indexing has some minor dependency on ConfigurationGroup env variable "If you got to the artifacts tab or a recent dev/eng build, you'll see that the Symbols folder is named `Symbols_$(ConfigurationGroup)`.

It's always been a very roundabout way (which AFAIK has been removed in .NET Core). Previously, you'd do this: ```c# AppDomain.CurrentDomain.SetData(""REGEX_DEFAULT_MATCH_TIMEOUT"", TimeSpan.FromSeconds(20)); ``` Or in ASP.NET: ```xml ``` Otherwise, we're depending on every developer to set their match timeouts inline, for each regex. The problems with that are: - It's either a maintenance burden, or we create *our own* global config anyway to use everywhere. - It defaults to failure if the developer forgets (creating a security and stability issue, since regexes can be a CPU-killing attack vector) If we had a static property, like this: ```c# namespace System.Text.RegularExpressions { public partial class Regex { // Set a default value, to be used if not overridden. public static TimeSpan DefaultMatchTimeout = Timeout.InfiniteTimeSpan; } } ``` ...we could do this gracefully in code.

The rationale is that run requires managed code but there are lot of scinerios where we need to build the native components without being able to run managed code (platform bring-up is one case). In general, we need to be able to build native code without invoking managed code and the use of the run tool in build-native is an impediment to that. This does imply a bit more cost in maintenance as we have to ensure that options to build-native remain somewhat consistent across platforms (and we need to do a better job of documenting them) but I think this cost is worth the flexibility. 15185 area-System.IO File.SetLastWriteTime does not seem to work when called repeatedly "```c# using System; using System.IO; using System.Threading; class Program { static void Main(string[] args) { var path = Path.GetTempFileName(); File.WriteAllText(path, ""foo""); for(var i = 0; i < 10; i++){ Console.WriteLine($""\n--> {new FileInfo(path).LastWriteTimeUtc}""); File.SetLastWriteTime(path, DateTime.Now + new TimeSpan(1, 0, 0)); Thread.Sleep(1000); Console.WriteLine($""--> {new FileInfo(path).LastWriteTimeUtc}""); } } } ``` Produces output: ``` --> 1/14/2017 12:51:52 AM --> 1/14/2017 1:51:52 AM --> 1/14/2017 1:51:52 AM --> 1/14/2017 1:51:53 AM --> 1/14/2017 1:51:53 AM --> 1/14/2017 1:51:54 AM --> 1/14/2017 1:51:54 AM --> 1/14/2017 1:51:55 AM --> 1/14/2017 1:51:55 AM --> 1/14/2017 1:51:56 AM --> 1/14/2017 1:51:56 AM --> 1/14/2017 1:51:57 AM --> 1/14/2017 1:51:57 AM --> 1/14/2017 1:51:58 AM --> 1/14/2017 1:51:58 AM --> 1/14/2017 1:51:59 AM --> 1/14/2017 1:51:59 AM --> 1/14/2017 1:52:00 AM --> 1/14/2017 1:52:00 AM --> 1/14/2017 1:52:01 AM ``` I'd expect all iterations to increment the time by one hour, but only the first one seems to do so.

I understand that making this change could quite possibly have far-reaching implications, so I guess at the very least I'd like to start a discussion and understand why it is the way it is. Currently [`HttpClient.SendAsync`](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/HttpClient.cs#L392) checks that the returned `HttpResponseMessage` is not null and throws an `InvalidOperationException` if it is. (Specifically [here](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/HttpClient.cs#L444-L447) and [here](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/HttpClient.cs#L476-L479).) I question why that check is necessary. It seems valid to want to implement a custom `HttpMessageHandler` that returns a null response in specific scenarios and not consider it an error condition. But with this behavior in `HttpClient`, you're basically forced to implement that flow through exception handling upstream. I'm curious to get the team's thoughts on this. Thanks! 15192 area-Meta Prefer using Array.Length as upper for loop limit "The JIT can't eliminate range checks if it can't ""see"" `Length` and uses loop cloning which generates a lot of code. Even in cases where not all range checks can be eliminated and loop cloning is used anyway it's still preferable to have fewer range checks.

In order to help understand what was going on I captured two TCPDUMP traces as I performed a simple Open on the SqlConnection object. One container running on HOST01 fails, whilst another running on HOST02 succeeds. The only difference i can see is the order in which DNS returns the primary and secondary - as discussed in #14978 where HOST01 returns the secondary first (this is the failing one) and HOST02 returns the primary. Of course the order shouldn't matter with MSN enabled which it is. From looking at the traces - it doesn't appear that MSN is working at all on Linux - I do not see a parallel invocation of the open socket that I was expecting. Rather it appears to just take the first IP address and try to connect to that. I'm happy to share the traces - only perhaps over something less public ?) I'm also happy to perform any other kind of testing that would help us get to a resolution. The setup is the same as before, only now with port specified (1433).

binary serializable We generally don’t want to add more types to be binary serializable in the framework, due to complexities and the fragility that it causes across version boundaries (remember that binary serialization has to be backward- and forward compatible). That being said, for `ValueTuple` we can likely convince ourselves that the serialization behavior is fixed and mostly a function of the types you instantiate the tuple with. It seems a resonable assumption to say that `ValueTuple` to be serializable if `T1`-`TN` are serializable. Not being binary serializable also makes it harder (and more fragile) for existing code to switch from `Tuple` to `ValueTuple`. 15231 area-Infrastructure Add build option for armel This PR fixes cross build fail on ubuntu-16.04 Signed-off-by: chunseoklee 15234 area-System.Diagnostics On Linux Win32Exception thrown by Process have incorrect error number `Process.Unix.cs` calls: ``` int errno = Interop.Sys.Kill(_processId, Interop.Sys.Signals.SIGKILL); int errno = Interop.Sys.GetPriority(Interop.Sys.PriorityWhich.PRIO_PROCESS, _processId, out pri); ``` which are implemented as ``` return kill(pid, signal); return getpriority(which, who); ``` These functions return -1 on error.

[See](http://stackoverflow.com/questions/41520319/alternatives-of-compiletomethod-in-net-standard) question on SO. After some research I found that problem is that `LambdaCompiler` is missing one overload ([see referencesource](https://referencesource.microsoft.com/#System.Core/Microsoft/Scripting/Compiler/LambdaCompiler.cs,122)) My question is if it's done intentionally (so API changed relative to full .Net) or it's just a mistake? If the latter I can create a pull request, because I don't see anything can break things down: the only difference with other overloads is that `MethodBuilder` is passing as parameter instead of creating it as local variable. Thus, there is no problem with implementation, then question is if we want to have following API?

These tests used to throw the following exception occasionally: `System.Xml.XmlException: The ':' character, hexadecimal value 0x3A, cannot be included in a name.` Which happens because in the random selection of valid characters to be included in the name of an element, the character `':'` was sometimes present, which is not allowed. This behavior is also the expected behavior in Full Framework. As a fix, `CharType.NameStartChar` and `CharType.NameChar` have been replaced with `CharType.NCNameStartChar` and `CharType.NCNameChar` which are exactly the same collection with only leaving `':'` out. Some more logging has also been added to these tests. cc: @danmosemsft @stephentoub @AlexGhiondea 15251 area-System.Runtime Add tests for enumerating ConditionalWeakTable Tests for the enumerable implementation in https://github.com/dotnet/coreclr/pull/8970 (updates to the refs and Clear tests will come separately).

There are Unix-specific functions/capabilities that are not exposed in our current set of APIs. For example, `chmod` and `chown` are commonly used functions on Unix to set file permissions, but we have no `System.IO` APIs that expose this functionality. It is hard to P/Invoke directly into “libc” from managed code because of type-size differences across platforms, and constants/error codes being different across platforms. ## Design tenets A guiding tenet is to keep any additional functionality and policy out of these exposed APIs. Instead, we will simply be exposing the OS function as raw as possible. - If deemed necessary, we can create ""helper"" methods in the future to make the APIs easier to invoke. One place where we will be adding functionality is to make the .NET APIs work across our supported platforms as seamless as possible. - An example here is error numbers may map to different values on different platforms. We will have a facility that will allow mapping raw platform error numbers to platform-independent error names like “EACCES”, “EPERM”, etc. A naming tenet will be to use the same name and casing as the C API, this includes method, parameter, enum value, and field names. This allows people to consult the appropriate man page if necessary. - One exception is type names will still be PascalCased, to make consuming code read like standard managed code. Having a class named “group” would look confusing to most .NET developers. ## Example Usages ```C# using System.Unix.Native; static void Main() { // chmod int result = UnixFunctions.chmod( ""/home/user/hello.txt"", FileModes.S_IRWXU | FileModes.S_IRGRP | FileModes.S_IROTH); if (result < 0) { UnixErrorInfo errorInfo = UnixErrorInfo.GetLastErrorInfo(); if (errorInfo.Error == UnixError.EPERM) // handle permission issue ... } // getgrnam_r unsafe { Group group = new Group(); Group* groupPointer; int bufferSize = 1024; byte* stackBuffer = stackalloc byte[bufferSize]; result = UnixFunctions.getgrnam_r(""somegroup"", ref group, stackBuffer, bufferSize, out groupPointer); if (result != 0) { UnixErrorInfo errorInfo = new UnixErrorInfo(result); while (errorInfo.Error == UnixError.ERANGE) { bufferSize *= 2; byte[] heapBuf = new byte[bufferSize]; fixed (byte* heapBuffer = heapBuf) { result = UnixFunctions.getgrnam_r(""somegroup"", ref group, heapBuffer, bufferSize, out groupPointer); if (result == 0) { break; } errorInfo = new UnixErrorInfo(result); } } } if (result != 0) // handle permission issue if (groupPointer == null) { // group wasn't found } else { string groupName = Marshal.PtrToStringAnsi(group.gr_name); string groupPassword = Marshal.PtrToStringAnsi(group.gr_passwd); uint groupId = group.gr_gid; List groupMembers = new List(); IntPtr* memberPointer = group.gr_mem; IntPtr currentMember = *memberPointer; while (currentMember != IntPtr.Zero) { groupMembers.Add(Marshal.PtrToStringAnsi(currentMember)); memberPointer++; currentMember = *memberPointer; } } } } ``` ## APIs to Expose The exposed functions will be implemented in phases. To determine the first phase of functions, I have analyzed [Mono](https://github.com/mono/mono/blob/master/mcs/class/Mono.Posix/Mono.Unix.Native/Syscall.cs), [Go](https://godoc.org/golang.org/x/sys/unix), and [Phython](https://docs.python.org/3/library/os.html) system functions. Phase 1 of this work will include functions that are: - Exposed by at least 2 out of the 3 platforms - POSIX compliant - Not Socket related (since there are already Socket APIs in .NET, these are lower priority) - Not Exec related (since there are already Process APIs in .NET) - Not Memory Map related (since there are already MemoryMappedFile APIs in .NET) - If there is an equivalent “_r” function, don’t expose the corresponding function that returns values that may point to a static area. This way our users don’t try executing non-thread safe functions. Ex. Expose “getgrnam_r()”, but don’t expose “getgrnam()”. That results in the following list of functions for Phase 1: 1. access 1. chdir 1. chmod 1. chown 1. close 1. closelog 1. confstr 1. creat 1. dup 1. dup2 1. faccessat 1. fchdir 1. fchmod 1. fchmodat 1. fchown 1. fchownat 1. fcntl 1. fdatasync 1. fpathconf 1. fstat 1. fstatvfs 1. fsync 1. ftruncate 1. getcwd 1. getegid 1. geteuid 1. getgid 1. getgrgid_r 1. getgrnam_r 1. getgroups 1. getlogin_r 1. getpgid 1. getpgrp 1. getpid 1. getppid 1. getpriority 1. getpwnam_r 1. getpwuid_r 1. getsid 1. gettimeofday 1. getuid 1. isatty 1. kill 1. lchown 1. link 1. linkat 1. lockf 1. lseek 1. lstat 1. mkdir 1. mkdirat 1. mkfifo 1. mknod 1. mknodat 1. mlock 1. mlockall 1. mprotect 1. munlock 1. munlockall 1. nanosleep 1. nice 1. open 1. openat 1. openlog 1. pathconf 1. pause 1. pipe 1. poll 1. posix_fadvise 1. posix_fallocate 1. posix_madvise 1. pread 1. pwrite 1. read 1. readlink 1. readv 1. rename 1. renameat 1. rmdir 1. setegid 1. seteuid 1. setgid 1. setlogmask 1. setpgid 1. setpgrp 1. setpriority 1. setregid 1. setreuid 1. setsid 1. setuid 1. stat 1. statvfs 1. strerror_r 1. symlink 1. symlinkat 1. sync 1. sysconf 1. syslog 1. tcgetpgrp 1. tcsetpgrp 1. time 1. times 1. truncate 1. ttyname_r 1. umask 1. uname 1. unlink 1. unlinkat 1. utime 1. utimes 1. wait 1. waitpid 1. write 1. writev " 15290 area-Serialization SoapEncodedSerializationTest_Enum Failed with PNSE The test is failing with PlatformNotSupportedException. ``` XmlSerializerTests.SoapEncodedSerializationTest_Enum [FAIL] System.InvalidOperationException : There was an error generating the XML document. ---- System.PlatformNotSupportedException : Operation is not supported on this platform.

I can modify the logic to avoid that, but right now I am just copying the PDB's into all of the `RuntimeDir` locations (same as the DLL's). * Add a filter parameter to OpenCover.exe so that it only collects data relevant to the assembly being tested (see **NOTE** below). * The way I am computing the name of the ""assembly being tested"" is quite hacky. I'd love a better way to get that information. * Add a filter parameter to the report generator so that we only report code coverage for the assembly being tested * Run tests serially when doing coverage runs. There was some logic in the targets for this before, but I think it stopped working during our refactoring.

This is because everything is filtered out by-default (except for the ""assembly being tested""). This is necessary because, with the new test structure, every runtime assembly's PDB is available, which would result in an insane amount of data being collected without any filtering. @weshaggard @karajas @joperezr cc: @stephentoub (The NOTE above will affect you if you're getting code coverage for System.Private.CoreLib)." 15309 area-System.Numerics Seg fault in System.Numerics.Vectors.Tests on Unix https://ci.dot.net/job/dotnet_corefx/job/master/job/osx_release_prtest/2194/consoleText ``` Discovering: System.Numerics.Vectors.Tests Discovered: System.Numerics.Vectors.Tests Starting: System.Numerics.Vectors.Tests /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_release_prtest/bin/AnyOS.AnyCPU.Release/System.Numerics.Vectors.Tests/netstandard1.3/RunTests.sh: line 80: 45186 Segmentation fault: 11 $RUNTIME_PATH/dotnet $EXECUTION_DIR/xunit.console.netcore.exe System.Numerics.Vectors.Tests.dll -noshadow -xml testResults.xml -notrait Benchmark=true -notrait category=nonnetcoreapp1.1tests -notrait category=IgnoreForCI -notrait category=OuterLoop -notrait category=failing -notrait category=nonosxtests /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx_release_prtest/src/System.Numerics.Vectors/tests Finished running tests.

Then if you write code with `ConcurrentStack` but later realize that the extra synchronization provided by that class isn't needed, you will be able to change the code to plain `Stack` without rewriting. 15323 area-Infrastructure Update the adding APIs guide We need to update https://github.com/dotnet/corefx/blob/master/Documentation/coding-guidelines/adding-api-guidelines.md based on the new engineering changes. 15328 area-System.Numerics Out of date comments in System.Numerics.Vectors "There is a comment at the beginning of Vectors.cs [https://github.com/dotnet/corefx/blob/master/src/System.Numerics.Vectors/src/System/Numerics/Vector.cs#L22-L32](url) > PATTERN: * if (Vector.IsHardwareAccelerated) { ... } * else { ... } * EXPLANATION * This pattern solves two problems: * 1. Allows us to unroll loops when we know the size (when no hardware acceleration is present) * 2. Allows reflection to work: * - If a method is called via reflection, it will not be ""intrinsified"", which would cause issues if we did * not provide an implementation for that case (i.e. if it only included a case which assumed 16-byte registers) * (NOTE: It is assumed that Vector.IsHardwareAccelerated will be a compile-time constant, eliminating these checks * from the JIT'd code.) This means that the Vector.IsHardwareAccelerated true path of each SIMD intrinsic fallback would execute in reflection calls. However, according to my experiment, CoreCLR’s behavior is different from the comment. The Vector.IsHardwareAccelerated true path cannot execute, even though it called by reflection. Usually, reflection calls of SIMD intrinsics also go to jited intrinsic. I detected that the true path only executes when the current base type is not supported by current SIMD intrinsic (in CoreCLR). For example, there is a SIMD intrinsic “DotProduct” in CoreCLR, which just supports Int, Long, Float, and Double. If we pass two vectors of Byte or Short, DotProduct would go to the C# fallback (the Vector.IsHardwareAccelerated true path). Consequently, here are two issues: 1. The comment is different from code's behavior (out of date comments?). 2. For most of the SIMD intrinsics, the code pattern ""if (Vector.IsHardwareAccelerated) { ... }"" looks useless. " 15329 area-System.Memory Proposal: Add Sort(...) extension methods for Span Currently, there is no way to sort native or fixed memory (e.g. coming from a pointer) in .NET, this proposal intends to fix that by adding sorting extension methods to `Span`, but also proposes some different overloads than seen on `Array` to allow for inlined comparisons via the possibility to use value type comparers. ### Proposed API Add a set of `Sort` extension methods to `Span` in `SpanExtensions`: ```csharp public static class SpanExtensions { public static void Sort(this Span span); public static void Sort(this Span span, TComparer comparer) where TComparer : IComparer; public static void Sort(this Span span, System.Comparison comparison); public static void Sort(this Span keys, Span items); public static void Sort(this Span keys, Span items, TComparer comparer) where TComparer : IComparer; public static void Sort(this Span keys, Span items, System.Comparison comparison); } ``` ### Rationale and Usage Provide a safe yet fast way of sorting of any type of contiguous memory; managed or unmanaged. #### Sorting Native Memory ```csharp var span = new Span(ptr, length); span.Sort(); // Sort elements in native memory ``` #### Sorting with Inlineable Comparer ```csharp struct ReverseComparer : IComparer { [MethodImpl(MethodImplOptions.AggressiveInlining)] public int Compare(int a, int b) { if (a == b) { return 0; } if (a > b) { return -1; } return 1; } } Span span = GetSomeSpan(); // Sort elements, in reverse order with inlined Compare, // without heap allocation for comparer span.Sort(new ReverseComparer()); ``` #### Sorting based on Lambda ```csharp Span span = GetSomeSpan(); // Sort elements, in reverse order with lambda/delegate span.Sort((a, b) => a == b ? 0 : (a > b ? -1 : 1)); ``` #### Sorting Compound Type ```csharp struct Compound { public float FeatureValue; public int FeatureIndex; public object Payload; } struct InlineableFeatureValueComparer : IComparer { [MethodImpl(MethodImplOptions.AggressiveInlining)] public int Compare(Compound a, Compound b) { if (a.FeatureValue == b.FeatureValue) { return 0; } if (a.FeatureValue < b.FeatureValue) { return -1; } return 1; } } var span = new Span(); span.Sort(); // Inlineable struct comparer var comparer = new InlineableFeatureValueComparer(); span.Sort(comparer); // Lambda comparer span.Sort((a, b) => a.FeatureValue == b.FeatureValue ? 0 : (a.FeatureValue < b.FeatureValue ? -1 : 1)); ``` The argumentation for adding this is: * To increase the efficiency of code doing sorting and prevent people from reinventing the wheel. * Allow performance optimizations depending on memory type and contents. * Allow sorting on contiguous memory of any kind. #### Use Cases In almost any domain where a high volume of data is processed with sorting being one operation and memory management (e.g. memory recycling, buffer pooling, native memory) is a must to achieve high performance with minimal latency, these sorts would be useful. Example domains are database engines (think indexing), computer vision, artificial intelligence etc. A concrete example could be in the training of Random Forests some methods employ feature sorting (with indeces) to find decision boundaries on. This involves a lot of data and data that can originate from unmanaged memory. ### Open Questions An important question regarding this proposal is whether the pattern with generic parameter `TComparer` (e.g. constrained to `where TComparer : IComparer`) is a pattern that can be approved. This pattern allows for inlineable comparers at the cost of increased code size, if no value type comparers are used, there should be no difference. This pattern is also used in the proposal for `BinarySearch` in https://github.com/dotnet/corefx/issues/15818 The API relies on being able to depend upon `System.Collections.Generic`, could this be an issue? @karelz @jkotas @jamesqo ### Updates UPDATE 1: Change API to be defined as extension methods. UPDATE 2: Add compounded type usage. UPDATE 3: Add link to BinarySearch and point on the pattern used. ### Existing Sort APIs A non-exhaustive list of existing sorting APIs is given below for comparison. #### `Array.Sort` Static Methods Found in [ref/System.Runtime.cs](https://github.com/dotnet/corefx/blob/master/src/System.Runtime/ref/System.Runtime.cs) ```csharp public static void Sort(System.Array array) { } public static void Sort(System.Array keys, System.Array items) { } public static void Sort(System.Array keys, System.Array items, System.Collections.IComparer comparer) { } public static void Sort(System.Array keys, System.Array items, int index, int length) { } public static void Sort(System.Array keys, System.Array items, int index, int length, System.Collections.IComparer comparer) { } public static void Sort(System.Array array, System.Collections.IComparer comparer) { } public static void Sort(System.Array array, int index, int length) { } public static void Sort(System.Array array, int index, int length, System.Collections.IComparer comparer) { } public static void Sort(T[] array) { } public static void Sort(T[] array, System.Collections.Generic.IComparer comparer) { } public static void Sort(T[] array, System.Comparison comparison) { } public static void Sort(T[] array, int index, int length) { } public static void Sort(T[] array, int index, int length, System.Collections.Generic.IComparer comparer) { } public static void Sort(TKey[] keys, TValue[] items) { } public static void Sort(TKey[] keys, TValue[] items, System.Collections.Generic.IComparer comparer) { } public static void Sort(TKey[] keys, TValue[] items, int index, int length) { } public static void Sort(TKey[] keys, TValue[] items, int index, int length, System.Collections.Generic.IComparer comparer) { } ``` #### `List.Sort` Member Methods Found in [ref/System.Collections.cs](https://github.com/dotnet/corefx/blob/master/src/System.Collections/ref/System.Collections.cs) ```csharp public partial class List : System.Collections.Generic.ICollection, System.Collections.Generic.IEnumerable, System.Collections.Generic.IList, System.Collections.Generic.IReadOnlyCollection, System.Collections.Generic.IReadOnlyList, System.Collections.ICollection, System.Collections.IEnumerable, System.Collections.IList { public void Sort() { } public void Sort(System.Collections.Generic.IComparer comparer) { } public void Sort(System.Comparison comparison) { } public void Sort(int index, int count, System.Collections.Generic.IComparer comparer) { } } ``` #### LINQ `OrderBy` Extension Methods Found in [ref/System.Linq.cs](https://github.com/dotnet/corefx/blob/master/src/System.Linq/ref/System.Linq.cs) ```csharp public static System.Linq.IOrderedEnumerable OrderBy(this System.Collections.Generic.IEnumerable source, System.Func keySelector) { throw null; } public static System.Linq.IOrderedEnumerable OrderBy(this System.Collections.Generic.IEnumerable source, System.Func keySelector, System.Collections.Generic.IComparer comparer) { throw null; } public static System.Linq.IOrderedEnumerable OrderByDescending(this System.Collections.Generic.IEnumerable source, System.Func keySelector) { throw null; } public static System.Linq.IOrderedEnumerable OrderByDescending(this System.Collections.Generic.IEnumerable source, System.Func keySelector, System.Collections.Generic.IComparer comparer) { throw null; } ``` 15330 area-System.IO Fast creating and removing files and directories causes UnauthorizedAccessException or DirectoryNotFoundException "When quickly creating and removing files exceptions are being thrown Repro: ```csharp using System; using System.IO; namespace ConsoleApplication { class Program { static void Main(string[] args) { for (int i = 0; i < 5000; i++) { string dirName = ""dfoo""; string fileName = ""foo.txt""; DirectoryInfo di = new DirectoryInfo(dirName); FileInfo fi = new FileInfo(Path.Combine(di.FullName, fileName)); di.Create(); File.WriteAllText(fi.FullName, ""foo""); File.Delete(Path.Combine(di.FullName, fileName)); Directory.Delete(di.FullName); Console.WriteLine(i); } } } } ``` This has reproed both on coreclr and Desktop - usually between 100-500 iterations (Ocassionally couple thousand) OS: Windows 10" 15331 area-System.Data SqlClient: Enable parallel connection opens for MultiSubnetFailover on Unix Looks like Unix networking APIs for connecting to multiple IP addresses simultaneously were not available when MultiSubnetFailover was implemented in CoreFx SqlClient. https://github.com/dotnet/corefx/blob/master/src/System.Data.SqlClient/src/System/Data/SqlClient/SNI/SNITcpHandle.cs#L191 15333 area-Infrastructure Update libcurl package on Centos outerloop image to latest version libcurl version on centos image in Jenkins is 7.29.0, and the other Unix Oses use 7.35.0.

This results in several problems, most glaringly Complex.Sqrt(-1)!=Complex.ImaginaryOne. It is also not optimized. I have changed the implementation to be the standard optimized complex square root algorithm well known in the numerical computing community. I also added a test for Complex.Sqrt(-1)==Complex.ImaginaryOne, which the current implementation fails and the new implementation passes. In the course of making this modification, I noticed several tests which demand NaNs be returned for extreme inputs to Complex.Asin, and for which NaNs are no longer returned after my changes to Complex.Sqrt. Actually, asin is perfectly well-defined and re-presentable for these inputs, and the tests were presumably added simply to reflect the current behavior of Complex.Asin. For the moment, I have simply deleted the erroneous tests. In future, Complex.Asin and Complex.Acos can be updated to use an optimized algorithm which will give correct results for all re-presentable inputs. 15339 area-Infrastructure Ensure we run UAP pinvoke checks regardless of TargetGroup Previously we'd only check pinvokes if a library specifically targeted UAP.

"We now have two versions of `System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverageAttribute`, the [publicly exposed version available to client code](https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.Tools/src/System/Diagnostics/CodeAnalysis/ExcludeFromCodeCoverageAttribute.cs) and the [internal version used through directly including the file](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Diagnostics/CodeAnalysis/ExcludeFromCodeCoverageAttribute.cs). Potentially the two could cause ambiguity. They also differ in two ways. 1. The internal version can be applied to assemblies. `ExcludeFromCodeCoverageAssemblyAttribute` was introduced to explicitly fit this purpose and reduce incompatibility of use. 2. The internal version is marked as `[Conditional(""DEBUG"")]`, reducing bloat in release assemblies. There are four things that can be done with this: 1. Leave things as they are. Pro: Don't fix what ain't broke. Con: Potential for ambiguity. 2. Remove the internal version, update to use the public version. Pro: Simple. Dogfooding. Con: Will bloat the release assemblies with attributes that aren't useful in release. 3. As above, but also change the public version to be `[Conditional(""DEBUG"")]`. Pro: As above and also reduce size of client release assemblies. Con: API change. While coverage of release builds is always likely to be strange, it may be still be used by someone and the effect undesirable. 4. Merge the internal version with `ExcludeFromCodeCoverageAssemblyAttribute` into a single `ExcludeFromCodeCoverageInternalAttribute` and use it consistently throughout. Pro: No bloat. No conflict with public API. Con: Not dogfooding. Introduces a difference in how we code corefx and how other projects are coded. Likely to be missed by new contributors, (or just anyone who didn't see this issue) who would expect to use `ExcludeFromCodeCoverageAttribute` as usual." 15388 area-Infrastructure EPPlus.Core incompatible with .NETFramework,Version=v4.5.2.

Additionally, all of the iterators have the same comparer so we only need to store the comparer in the latest node. - Introduce `Set.UnionWith` for brevity and move `SingleLinkedNode` into its own file. **edit:** Was finally able to run [perf tests](https://gist.github.com/jamesqo/2039702fe841a5264dd73b47c6e9efd5) for this. GCs have increased, as expected, because there is a substantial reduction in leaked memory. `Concat` and `Union` see 50-60% reductions in leaked memory, `Append` and `Prepend` about 20%. **edit 2:** Ignore the results for `Concat`, I hit a few complications there and the changes became pretty big.

I narrowed down the problem with this test case demonstrating different behavior for different collection classes that implement the same interface. Specifically ``Contains(null)`` throws a ``ArgumentNullException`` for ``ImmutableSortedSet`` but not for ``Array`` or the mutable ``SortedSet``. ```c# using System.Collections.Generic; using System.Collections.Immutable; using Xunit; public class SortedSetSpec { [Fact] public void WTFNullCheck() { var data = new[] {""a"", ""b"", ""c"", ""d""}; SortedSet ss = new SortedSet(data); ImmutableSortedSet iss = ss.ToImmutableSortedSet(); // This passes data.Contains(null).Should().BeFalse(); // This passes ss.Contains(null).Should().BeFalse(); // This throws an exception iss.Contains(null).Should().BeFalse(); } } ``` Given that all classes Array / SortedSet and ImmutableSortedSet implement ``ICollection`` shouldn't they have the same behavior on the ``Contains(null)`` call? The bug manifested itself when I data bound an ``ImmutableSortedSet`` to the ``ItemsSource`` property of a listbox. ```xml ``` The problem is that at some point deep in the databinding code ListBox (aka Selector ) asks the collection ``Contains(null)``?? and then it crashes if I've databound an ``ImmutableSortedSet``. So is this a bug with ``ImmutableCollections`` or with ``WPF`` or is it expected behavior and I should know better than to use ``ImmutableSortedSet``?

This is because although it has a constructor that allows a different comparer to be passed in, that constructor is never actually called. And during `Equals`, it uses that default comparer for comparing two sorted sets and leaves the equality comparer which was handed to it from `CreateSetComparer` completely out of the equation. The fix would be to remove the `_comparer` field and use the equality comparer for everything. 15411 area-Meta Cleanup: remove empty try's We have about 20 instances of `try { }` See https://github.com/dotnet/coreclr/issues/8924. The PR https://github.com/dotnet/coreclr/pull/8949 makes sure they are not represented in generated code so this is just minor code cleanup. 15412 area-System.Memory Add GC reporting test for `Span` 15413 area-System.Collections Deduplicate lots of AVL tree implementations in System.Collections.Immutable I am in the process of separating out some immutable collection types into new files, and I counted 4 different AVL tree implementations in the assembly-- one in `ImmutableList`, one in `ImmutableSortedDictionary`, one in `ImmutableSortedSet`, and one in `SortedInt32KeyNode`. Many of the methods in one file look like they're copied and pasted from another, which is definitely not ideal. (e.g. Remove operations: [ISS](https://github.com/dotnet/corefx/blob/51c048850ab38fe9618592b04a29e52a44534039/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableSortedSet_1.cs#L1801), [ISD](https://github.com/dotnet/corefx/blob/51c048850ab38fe9618592b04a29e52a44534039/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableSortedDictionary_2.cs#L1884), [IL](https://github.com/dotnet/corefx/blob/51c048850ab38fe9618592b04a29e52a44534039/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableList_1.cs#L2141), [SI32KN](https://github.com/dotnet/corefx/blob/51c048850ab38fe9618592b04a29e52a44534039/src/System.Collections.Immutable/src/System/Collections/Immutable/SortedInt32KeyNode.cs#L463)) ## Possible solutions - One way I can think of to work around this is to have one `AvlNode` class that contains all of the central logic. All of the other node types can be converted to one-field struct wrappers around this type that implement their custom logic, e.g. ```c# public sealed class AvlNode { // Tree balancing operations, MutateRight/Left, field declarations for _height/_left/_right, etc. } public class ImmutableList { public struct Node : IBinaryTree, IEnumerable { private readonly AvlNode _underlying; // Methods that make sense for ImmutableList's Node } } ``` As long as we keep the struct one field long, we should not suffer from a perf hit because the JIT generates really good code for tiny struct wrappers. Additionally, we get to keep the underlying node type sealed. **Complications:** One caveat that this approach would have is that a nil (an actual nil, not an empty) node would now be represented as a default struct instead of null. So we'd likely have to introduce `IsDefault`, `IsEmpty`, and `IsDefaultOrEmpty` properties for each struct node type and change all of the call sites/asserts to use those. Another is that since the types are now structs they will be boxed at any call sites they are being used as an interface, for example `IBinaryTree` / `IEnumerable` in the above example. I don't expect there are many of those call sites though (if I understood the code correctly, `IBinaryTree` is for testing purposes?) so maybe that won't be an issue. /cc @ianhays @AArnott, please let me know what you think of this solution. 15414 area-System.Reflection Bring back System.Reflection.Emit.TypeBuilder.CreateType API 15416 area-System.Collections Split up some immutable collection types into new files I found it unwieldy to scroll through some immutable collection files like `ImmutableSortedDictionary_2.cs`, which currently contains over 2000 lines of code. So I decided to split out a bunch of nested types into new files for that and some other types. You can view the full list of files in the `.csproj` diff; each debugger proxy/enumerator/AVL tree implementation gets its own file. /cc @AArnott @ianhays 15419 area-System.Data "[CI Failure] System.Data.SqlClient.TdsParser.TryProcessError: ""class and token don't match!"""

There is a new BuildTools setup flow that CLI and BuildTools use called bootstrap that allows significantly more code sharing by directly downloading a BuildTools script which handles further steps. This reduces the complexity in CoreFX itself and reduces the chance the BuildTools init flow diverges from other repositories' (like CoreCLR's). The bootstrap flow is also easier to improve, because the improvements only need to be done in one place rather than being ported across many repos. See https://github.com/dotnet/buildtools/issues/558. Living list of things that should be fixed before CoreFX adoption (feel free to edit): * Make script download repeatable. Currently it downloads the latest in a branch, but a commit hash should be used. This is the case for the bootstrap.ps1/sh download and the dotnet-install.ps1/sh download inside the bootstrap script. https://github.com/dotnet/buildtools/issues/1225 * A change in CLI version but not BuildTools doesn't re-init the `Tools` directory. https://github.com/dotnet/buildtools/issues/1192 Any other known issues pre-CoreFX adoption, @weshaggard @crummel ? /cc @ellismg @dleeapho @markwilkie 15429 area-Infrastructure CodeCoverage target clean-up See https://github.com/dotnet/corefx/pull/15397#discussion_r97456921.

Compression is a per-message flag set on the first frame using the RSV1 bit. SendAsync sends frames and only takes the buffer, message type, an EndOfMessage bool, and a cancellationToken. There's no simple way to indicate if the data is or should be compressed / transformed. Possible solutions: - Enable compression for all messages, don't provide a per message option - Add a new overload of SendAsync with a compression / RSV1 flag. (Requires changing the core WebSocket abstraction) - Add a property to WebSocket bool CompressOutput that can be toggled between messages (Requires changing the core WebSocket abstraction) - Overload WebSocketMessageType with CompressedBinary and CompressedText. As an enum we may be able to temporarily pass data through here by casting non-standard values. The enum values already do not map directly to the WebSocket frame type values. ReceiveAsync is easier, it could: - Decompress the content internally - Add a flag to WebSocketReceiveResult indicating if the content was compressed. - Use the same WebSocketMessageType overloads from above indicating if the content is compressed (but only if it does not decompress it internally, don't want to confuse consumers). The compression extension could not be correctly implemented as wrapper over the current WebSocket API due to the framing requirement. Compression either needs to be built in or the API needs to expose additional frame fields (e.g. RSV1). 15431 area-System.Data Resolved connection leak in SNI by adding dispose for underlying TCPstream in SNITcpHandle.Dispose() Fix for SqlConnection TCP connection leak. Copied from master branch PR https://github.com/dotnet/corefx/pull/13653 Originally caused by https://github.com/dotnet/corefx/commit/30abd30421289509cd3bd18a9114501afdc0fb7c which removed a TcpClient.Dispose() in SNITcpHandle This is a fix for https://github.com/dotnet/corefx/issues/13422 15432 area-System.Net Reduce HttpClient overheads on Unix This PR provides several commits for improving HttpClient performance on Unix (some apply to Windows as well): - When POST'ing data via HttpClient, even if only a small amount of content, libcurl ends up sending out two packets for the request. A commit adds an optimization whereby if a ByteArrayContent (or derived content type) is used such that we have all of the content in-memory and don't need to read from the content stream, we can instead provide the data to libcurl in advance. This both lets it optimize the size of its writes (and thus the number of packets) and lets us avoid the overhead of the machinery involved in having libcurl pull from the request content stream. - Both CurlHandler and WinHttpHandler know about a set of headers for which we have constant strings available, and they avoid allocating strings for such headers. But CurlHandler has a bug where it passes in the wrong span, which means it always fails to match, and ends up allocating the string anyway. - When CurlResponseStream is used from a consumer that uses Begin/EndRead, these calls end up going to the base implementation, which queues a work item that calls Read, which in turn calls ReadAsync and blocks waiting for it to complete. The fix is to just override Begin/EndRead and wrap ReadAsync directly. - Getting the request content stream is resulting in a fair number of unnecessary allocations and delegate invocations for a common case where the stream is returned synchronously. - Lots of intermediate string values are getting allocated when rendering headers to strings. This change uses StringBuffer and StringBufferCache to avoid most of them. - When rendering headers, we're often making multiple calls to GetValuesAsStrings indirectly when we can get away with just one call (and resulting string[] allocation). - Every request is allocating a Uri based on the actual url libcurl reports, but we only need to do that if it's actually changed. - There's no need to do certificate revocation checking when the client is building a chain for its own certs. But it's taking a significant chunk of time... one of our outerloop tests is frequently timing out even as a result. cc: @mikeharder, @cesarbs, @davidsh, @cipop, @geoffkizer, @bartonjs @Priya91 15434 area-System.Memory S.M.Span: Handle OutOfMemoryException in longer-than-uint-MaxValue Clear tests Handle OutOfMemoryException in longer-than-uint-MaxValue Clear test by catching the exception and skipping.

Adds a flag that can be passed to the build to disable symbol stripping. Pass `noStripSymbols` to `src/Native/build-native.sh`, or pass `-noStripSymbols` to `build.sh` or `build-native.sh`. `build.sh` will try to pass it to `build-managed.sh`, so I have it no-op in the managed build. If native symbols aren't stripped, no symbol package is created and the build exits normally. This is the same behavior as a Debug build, which never strips symbols due to the RELEASE check in the CMake file. The flag is negative to preserve official build behavior. To clean that up, I could change it to `stripSymbols` and make the official builds pass it in. We could remove the RELEASE flag check, then. @ellismg @chcosta Think that's a good way to go? One thing I noticed about this is that CMake doesn't rebuild when I change whether or not I pass `noStripSymbols`. I don't know if this is a big issue. I think the cause is conditionally doing `add_custom_command`, because we aren't giving CMake a way to tell if the command's been done given the input arguments. I can look at fixing that before merging this PR if it's important. 15441 area-Infrastructure Allow AdditionalCodeCoverageAssemblies to be specified in project files Fixes #15429 @weshaggard @JonHanna 15443 area-Meta Remove calls to Contract methods/or change to Debug.Assert as appropriate There are a bunch of calls to `Contract` methods in corefx: see [gist][1].

Instead of catching exception from TryEnsureSufficientExecutionStack. Fixes #11556 If `MaxExecutionStackCount` is hit this just lets the caller try to use the current stack. This changes the behaviour with code that pushes past the limit of the stack guard from throwing `InsufficientExecutionStackException` to throwing `StackOverflowException` (unless the caller was *really* lucky!). This seems reasonable in that it should be rare, is what more developers would expect from the sort of deeply recursive code that could do that, and is what would have happened prior to #11091, except it'll have gone through 1024 stacks' worth of calls before it does so.

For each non-generic `Enum` method there should be an equivalent generic version. There should be better support for flag enums, bit-masked enums with the `FlagsAttribute` applied. The performance of `Enum`'s methods that utilize reflection should be improved. Support for enum validation should be improved to support flag enums. Additionally, there should be added direct support for the retrieval of `Attribute`s applied to enum members. ## Rationale and Usage 1. Nearly all of `Enum`'s static methods are non-generic leading to the following issues. * Requires boxing for methods with enum input parameters losing type-safety, eg. `IsDefined` and `GetName`. * Requires casting/unboxing for methods with an enum return value, eg. `ToObject`, `Parse`, and `GetValues`. * Requires the enum type to be explicitly specified as an argument. * Requires invocation using static method syntax. 2. Support for flag enums is limited to just the `HasFlag` method which isn't type-safe, is inefficient, and is ambiguous as to whether it indicates if the value has all or any of the specified flags. It's also visible to all enum values whether it's a flag enum or not. 3. Many of `Enum`'s methods use reflection on each invocation instead of caching the reflection results leading to poor performance. 4. Built-in support for enum validation is currently limited to the `IsDefined` method which doesn't support flag enum combinations and is inefficient due to a lack of caching of reflection results. 5. The pattern to associate extra data with an enum member using `Attribute`s is not directly supported and instead requires users to manually retrieve the `Attribute`s via reflection. This pattern is commonly used on enums using the `DescriptionAttribute`, `EnumMemberAttribute`, and `DisplayAttribute`. With this proposal implemented what used to be this to validate a standard enum value ```c# MyEnum value = ???; bool isValid = Enum.IsDefined(typeof(MyEnum), value); ``` now becomes this ```c# MyEnum value = ???; bool isValid = value.IsDefined(); ``` And what used to be this to validate a flag enum value ```c# MyFlagEnum value = ???; bool isValid = (value & Enum.GetValues(typeof(MyFlagEnum)) .Cast() .Aggregate((working, next) => working | next)) == value; ``` now becomes just this ```c# MyFlagEnum value = ???; bool isValid = value.IsValidFlagCombination(); ``` And what used to be this to retrieve both the names and values of an enum's members ```c# var values = (MyEnum[])Enum.GetValues(typeof(MyEnum)); var names = Enum.GetNames(typeof(MyEnum)); for (int i = 0; i < values.Length; ++i) { MyEnum value = values[i]; string name = names[i]; } ``` now becomes this ```c# foreach (var member in Enum.GetMembers()) { MyEnum value = member.Value; string name = member.Name; } ``` And what used to be this to retrieve the `DescriptionAttribute.Description` of an enum member ```c# MyEnum value = ???; string description = ((DescriptionAttribute)Attribute.GetCustomAttribute( typeof(MyEnum).GetField(value.ToString()), typeof(DescriptionAttribute), false))?.Description; ``` now becomes this ```c# MyEnum value = ???; string description = value.GetAttributes()?.Get()?.Description; ``` With this implemented it will address #594, #693, #10692, #10908, and #11073. ## Proposed API I've split this proposal up into a base API addition as well as an `EnumMember` support addition in case `EnumMember` support is decided not to be desired for `corefx`. ### Base ```diff namespace System { public abstract class Enum : ValueType, IComparable, IConvertible, IFormattable { - public bool HasFlag(Enum flag);

+ public bool Has(Type attributeType); } } ``` ## API Details This proposal makes use of two `C#` language features that need to be added in order for this proposal to make the most impact. The first one is that `Enum` needs to be added as a valid type argument constraint in `C#` as is proposed in [csharplang#104](https://github.com/dotnet/csharplang/issues/104). `C#`, `VB`, and `F#` are currently able to consume generic methods with an `Enum` type argument constraint but just can't express them. This API cannot be implemented reasonably without this being added as that would mean no extension methods due to promotion of static method to an extension method later being a breaking change due to [csharplang#665](https://github.com/dotnet/csharplang/issues/665). Additionally, adding the `Enum` constraint later would be a breaking change and may not be acceptable. The second one is that this proposal specifies extension methods within `System.Enum` and as such requires `C#` to allow extension methods within non-static classes as is proposed in [csharplang#301](https://github.com/dotnet/csharplang/issues/301). This would not have to be implemented before the API ships as it wouldn't be a breaking change to promote a static method to be an extension method in a non-static class because that's not currently possible. The extension method promotion would just need to be done at the same time as the language release that allows extension methods in non-static classes. ### Base API Details #### `Enum` API Details * `HasFlag` is being deprecated as it's ambiguous and clutters up the intellisense as it's always accessible to all enum values. Using `System.Flags.FlagEnum.HasAllFlags` removes the naming ambiguity and since it's in a separate namespace it'll only be visible within a source file when the file explicitly includes `System.Flags`. * `Enum` has been added to the type constraints of the generic versions of `Parse` and `TryParse`. This would be a breaking change if another generic method that is constrained to `struct` currently calls these methods. #### `FlagEnum` API Details The flag enum operations are defined in the separate class `FlagEnum` in the namespace `System.Flags` to make flag enum extension methods' visibility optional. * `CombineFlags` returns the bitwise OR of the values. The name was chosen as it mirrors the naming of `Delegate.Combine`. * `CommonFlags` returns the bitwise AND of the values. * `AllFlags` returns all enum members' values that are powers of two bitwise ORed together. * `GetFlags` retrieves each valid flag included in the value in increasing significance bit order. * `HasAllFlags` indicates if the value contains all of the specified flags, equivalent to the current `HasFlag`. * `HasAnyFlags` indicates if the value contains any of the specified flags. * `IsFlagEnum` indicates if the enum has the `FlagsAttribute` applied. * `IsValidFlagCombination` is defined as `(value & AllFlags) == value`. * `RemoveFlags` returns value with all of the specified flags removed and is defined as `(value & (~flags))`. The name was chosen as it mirrors the naming of `Delegate.Remove`. #### `PrimaryAttribute` API Details * The `PrimaryAttribute` is used to specify what enum member to retrieve when there are multiple enum members with the same value. It could be used for more than just enum members for cases in code where there is ambiguity. ### `EnumMember` Support API Details #### `Enum` API Details * `GetAttributes` retrieves the `AttributeCollection` of an enum member with the specified value. If there are multiple enum members with the specified value the enum member marked with the `PrimaryAttribute` will be used. If there are no enum members with the specified value `null` is returned. * `GetMember` retrieves the `EnumMember` with the specified value or name. If there are multiple enum members with the specified value the enum member marked with the `PrimaryAttribute` will be retrieved. If there are no enum members with the specified value or name `null` is returned. * `GetMembers` retrieves all of the `EnumMember`s of the specified enum in increasing significance bit order by their respective values. #### `EnumMember` API Details * `EnumMember` and `EnumMember` are a new object model formed over an enum member which include its name, value, and attributes. They only have internal constructors and there is only one instance of `EnumMember` created for each enum member thus one can use `ReferenceEquals` for determining equality. This also prevents allocations after the first retrieval. * It seems there's no reason to constrain `TEnum` in `EnumMember` to an `Enum` as it's not publicly constructible and being unconstrained would be beneficial in generic programming. #### `AttributeCollection` API Details * `Get` returns the first `Attribute` in the collection that is assignable to the specified attribute type if available otherwise `null`. * `GetAll` returns all `Attribute`s in the collection that are assignable to the specified attribute type. * `Has` indicates if any `Attribute`s in the collection are assignable to the specified attribute type. * Type needs to be moved from the `System.ComponentModel.TypeConverter` assembly into `mscorlib` while adding an automatic binding redirect. ## Implementation Details This proposal stems from my work on the open source library [Enums.NET](https://github.com/TylerBrinkley/Enums.NET) which addresses each of these issues and will be the basis for an implementation. For efficiency this is how `Enums.NET` is implemented. First, using `Enum` as a generic type argument causes generic code-explosion in today's runtimes so it's essential that it's included sparingly. For this reason most logic is contained in an [`EnumCache`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/EnumCache.cs#L42) object where `TInt` is the underlying type and `TIntProvider` is the underlying type's operations provider which implements the interface [`INumericProvider`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/Numerics/INumericProvider.cs#L31) which provides the bitwise operations and other needed operations. Including the `TIntProvider` as a type parameter allows the runtime to inline calls to its methods so there's no interface method dispatch, a technique described in this [generic calculations article](https://www.codeproject.com/articles/8531/using-generics-for-calculations). Now how can one access this `EnumCache` object when the caller only has the enum type as a generic type argument? This is solved by the bridge-like object [`EnumInfo`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/EnumInfo.cs#L45) which implements the interfaces [`IEnumInfo`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/IEnumInfo.cs#L101) for generic methods and [`IEnumInfo`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/IEnumInfo.cs#L44) for non-generic methods. It simply acts as a bridge to delegate calls from the interfaces to `EnumCache`. In order to do that it needs to be able to efficiently convert values between `TEnum` and `TInt`. This is performed by the conversion methods [`ToInt`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/EnumInfo.cs#L61) and [`ToEnum`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/EnumInfo.cs#L71) which are declared as `extern` methods for efficiency so that they're simply defined as casts from one type to the other. This `EnumInfo` is created via reflection upon it's first call and is stored in the static property [`Enums.Info`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/Enums.cs#L1592) as an `IEnumInfo` which is then called by [`Enums`](https://github.com/TylerBrinkley/Enums.NET/blob/ca49e29a8effe0460135eeb10eed6cc1ec907188/Src/Enums.NET/Enums.cs#L38)'s generic methods. For non-generic methods a `Dictionary` is used to retrieve the `IEnumInfo` to use. ## Open Questions * Can and should `Enum` implement `IComparable` and `IEquatable` as proposed in #8973? * Is adding the `Enum` constraint to the generic versions of `Enum.Parse` and `Enum.TryParse` an acceptable breaking change? ## Updates * Added more implementation details. * Added more API details. * Added enumerating members usage example. * Added generic versions of instance methods for performance reasons. * Removed the `System.Enums` namespace and moved its members into the `System` namespace. * Moved `PrimaryAttribute` into the `System.ComponentModel` namespace and switched to using the existing `System.ComponentModel.AttributeCollection`. * Removed `IsValid` method as it's meaning is rather subjective and promoted `IsValidFlagCombination` as an extension method. * Renamed `GetAllFlags` to `AllFlags` as it more closely resembles a property but can't be because it is generic. Similar naming to `Array.Empty`. * Removed `EnumComparer` as one can just use `Comparer.Default` and `EqualityComparer.Default` instead. * Split the proposed API to a base API addition and an `EnumMember` support API addition." 15454 area-Infrastructure [NO-MERGE] Changes to make projects build against the TargetingPack based on Configuration instead of BuildConfiguration @dotnet-bot skip ci please Sharing the work I have so far for an initial review. cc: @weshaggard @ericstj With these changes I have the refs, shims and src projects building succesfully. I am however hitting two issues when running build.cmd: - Bin clash logger is detecting issues that I haven't checked yet - Package validation is detecting some cycles in our runtime dir like for example: `netstandard > System.Data.Common > System.Xml.ReaderWriter > S ystem.Private.Xml > Microsoft.Win32.Registry > netstandard` which might be difficult to fix. @ericstj I'll check with you tomorrow how to address them. FYI: @tarekgh @mellinoe 15455 area-System.Numerics Complex.Asin gives bad values for extreme arguments For all Complex values z in the representable range, the value of asin(z) lies in the representable range. For example for large real m ~ Double.MaxValue, asin(m) ~ \pi / 2 + \ln (2 m) i ~ 1.5708 + 710.476 i. (The sign of the imaginary part may change depending on the phase convention, but the magnitude shouldn't.) But the Complex.Asin method returns NaNs for these arguments, and indeed for more arguments with |z| > Sqrt(Math.Double), presumably because of internal overflow when calculating z * z. Complex.Acos similiarly gives unnecessary NaNs for large arguments. These methods should be fixed so as to give accurate results over the entire representable range. 15456 area-Infrastructure Fix P2P reference Configuration selection Previously we'd always choose Configuration for P2Ps based on BuildConfiguration. This was incorrect and could result in netstandard configurations building against netcoreapp references. Fix this by doing configuration selection in the referencing project. I had to fix a number of projects after making this change. These were all cases where we were building a OS-agnostic configuration and referencing an OS-specific library. Or building netstandard libraries referencing netcoreapp libraries. I've also added hooks to build all configurations. To do this from a traversal set /p:BuildAllConfigurations=true. To do this from a project build with /t:BuildAll. /cc @weshaggard @joperezr @chcosta 15460 area-System.Net Avoid creating a new HttpClient per HttpWebRequest in some cases In .NET Core, HttpWebRequest is layered on top of HttpClient and HttpClientHandler. Due to the mismatch in APIs, the implementation creates a new HttpClient per HttpWebRequest, which is very inefficient. But those costs can be avoided in some circumstances. In particular, we can have a shared HttpClient configured with the same defaults that HttpWebRequest has; then as long as none of the settings on the HttpWebRequest have been changed to veer from the defaults, the shared HttpClient instance can be used rather than creating a new one. 15461 area-System.Net Fix typo in HttpClient private method name 15462 area-System.Net Avoid InternalGetCookies costs when there are no cookies Calling CookieContainer.GetCookieHeader results in a bunch of work and allocations, including a list, an array, several strings, etc., but none of that is necessary if there aren't any cookies in the container anyway.

This is showing up in traces of HttpClient. cc: @davidsh, @cipop, @geoffkizer, @mikeharder, @cesarbs 15464 area-Microsoft.CSharp Microsoft.CSharp.RuntimeBinder constant folding incorrect in several ways Given: ```C# var x = CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.Constant, null); var y = CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.Constant, null); var binder = Microsoft.CSharp.RuntimeBinder.Binder.BinaryOperation(CSharpBinderFlags.None, ExpressionType.Divide, GetType(), new[] {x, y}); var callsite = CallSite>.Create(binder); callsite.Target(callsite, 8, 0); ``` We would expect the last line to throw a `RuntimeBinderException` due to the divide by constant zero. Instead it throws `OverflowException` (in debug it throws an assertion failure). Of the other integer types, `uint`, `long` and `ulong` will all throw a `DivideByZeroException` while all the others throw `OverflowException`. 15466 area-Microsoft.CSharp Catch divide-by-constant-zero in Microsoft.CSharp.RuntimeBinder Fixes #15464 15467 area-Microsoft.CSharp Are constant-folding and checks in Microsoft.CSharp.RuntimeBinder useful. #15464 notes a bug in the constant-folding RuntimeBinder does, but considering that with the code emitted by the C# compiler when used with `dynamic` such checks and folding would already be done prior to the dynamic binding, is this constant-folding useful? Is the cost of checking if they can be applied when binding worth the benefit gained when running? Would it be better to just always evaluate at runtime? One downside I can definitely see to removing them is the difference in exceptions thrown, but if that currently isn't correct anyway, it's not that big a loss. 15469 area-System.Threading Need for a generic IAwaitable and library of combinators Today custom awaiters fall short for several reasons: - Inability to declare an async methods as anything but Task (better with C# 7 and task likes) - Methods that work on any task like (Awaitable.WhenAll, Awaitable.WhenAny etc). - A first class interface for awaiting (IAwaiter) can be implemented things like cancellation tokens and other awaitable things (events?) I haven't thought through an API proposal as yet, just throwing this out there for now. Another alternative would be to expose Task from all APIs (like Cancellation token) but that doesn't seem like a very efficient solution. /cc @stephentoub 15470 area-System.Runtime Use `throw null` in System.Runtime ref Some of the APIs that were previously `#if netcoreapp11` were using the old `return default(T)` pattern.

It would turn code that looks like this: ```C# await Task.Run(() => DoSomething()); ``` ```C# await ThreadPool.Yield(); // Now on a thread pool thread so we can call some user code DoSomething(); ``` /cc @stephentoub 15494 area-System.Data Implement truly parallel MultiSubnetFailover connections in managed SNI CC @saurabh500 @stephentoub Fixes issue: https://github.com/dotnet/corefx/issues/15331 15495 area-Infrastructure Fix uap Configurations for a few libraries With this few changes the TargetingPack that we produce for uap (and uapaot) will match the set of reference assemblies we had supported on uap10.1 before the dev/eng merge cc: @weshaggard @ericstj Next, I'll do the src configs. 15499 area-Meta Use `throw null` in refs Follow-up of #15470, this time grepping the entire source: Use `throw null` in refs instead of `return default(T)` or `return 0`. 15502 area-System.Security Test failure: System.Security.AccessControl.Tests.DiscretionaryAcl_Constructor1/Constructor1_AdditionalTestCases Opened on behalf of @Jiayili1 The test `System.Security.AccessControl.Tests.DiscretionaryAcl_Constructor1/Constructor1_AdditionalTestCases` has failed.

And core-setup build needs CoreCLR & CoreFX nuget packages. We can build CoreCLR without target platform nuget packages dependency. But CoreFX and core-setup have target platform nuget package dependency for each other.

I would really appreciate if anyone can provide me any reference or an idea how to do it it will be really helpful. Using .net framework it's not a problem, but using .net core I don't understand what will be the best way to go. To be more specific about my question, I would generalize it: That is, I want to make HttpClient calls to the server, to request for the api to the server and get the response back from the server in the form of http requests and response.

Doing so incurs heap allocations, not only for the backing vector for the list, but also for the `List` itself since it is a class. It would be great to have a struct alternative to `List` to reduce unnecessary allocations. ## Proposal We should add the `ArrayBuilder` struct: ```c# public struct ArrayBuilder : IList, IReadOnlyList { public ArrayBuilder(); public ArrayBuilder(IEnumerable items); public int Capacity { get; } public int Count { get; } public ref T this[int index] { get; } public void Add(T item); public void AddRange(IEnumerable items); public void Clear(); public void Contains(T item); public void CopyTo(T[] array); public void CopyTo(T[] array, int arrayIndex); public void CopyTo(int index, T[] array, int arrayIndex, int count); public Enumerator GetEnumerator(); public int IndexOf(T item); public void Insert(int index, T item); public bool Remove(T item); public void RemoveAt(int index); public T[] ToArray(); // Resets the ArrayBuilder after it's called. public ArraySegment ToArraySegment(); // Does not copy, resets the ArrayBuilder after it's called. public void UncheckedAdd(T item); // Assumes there is enough room in the backing array. bool ICollection.IsReadOnly { get; } IEnumerator IEnumerable.GetEnumerator(); IEnumerator IEnumerable.GetEnumerator(); public struct Enumerator : IEnumerator { public T Current { get; } public void Dispose(); public bool MoveNext(); void IEnumerator.Reset(); } } ``` ## Notes - Because C# does not support parameterless struct constructors, we won't be able to set the underlying array to an empty one when the `ArrayBuilder` is first created, so we'll have to incur [an extra null check](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/ArrayBuilder.cs#L38) on every `Add` where List does not. - The alternatives would be to have a factory method `ArrayBuilder.Create()`, or forcing the user to pass in a dummy parameter to the constructor, so we could do initialization work. However, it seems better to incur the check than to sacrifice the user experience. And if parameterless struct constructors are enabled in the future then we can remove it without breaking anything. - The builder will use the exact same buffer sizes as `List` (0, 4, 8, ...) to make it a no-brainer to switch from List to ArrayBuilder in local variables. - `UncheckedAdd` will be similar to `Add`, but won't check if there's more room in the array. If there isn't, it will generate an `IndexOutOfRangeException`. See [implementation](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/ArrayBuilder.cs#L118) - `ToArray` will reset the ArrayBuilder after it's called. The reason is we can employ an optimization where if the count of the builder is equal to its' capacity, we just hand back the underlying array and don't do any copying. However, this could cause issues if the same array is handed back twice, and modified by both callers. To prevent these errors we will reset the ArrayBuilder back to its initial state after one call. - In the [current implementation](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/ArrayBuilder.cs#L102) we take a different approach and invalidate the builder instead of resetting it after `ToArray` is called. However, I'm deciding not to go with that approach because then we will have another state we have to account for in every method. - This is primarily meant to be used for scenarios when the size of the array is small. Sometime later (after some discussion has ensued here but before the API is approved), I will publish a separate proposal on [`LargeArrayBuilder`](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/LargeArrayBuilder.cs) which uses a separate buffering strategy that reduces allocations by 1/3. 15574 area-System.Net use SOCKETSTRESS_ITERATIONS env var to allow longer stress runs Base stress test takes about 3.5 seconds to run on my machine, which isn't very long.

An index is incremented with each pass through `args`, so now it's an array just use `for(;;)` access with it as the index. `parameters` will always end up as the same size as `args`, so preallocate an array rather than growing a `List`. Use direct indexing rather than Linq's `First` and `FirstOrDefault`. Allow for binding restrictions with literal `NaN` (we can't use `==` as the previous comment said, but we can call `IsNaN`). Create block for increment/decrement writeback directly, rather than growing a `List`.

This is not however enforced, so the assertion isn't valid. With either of them, excessive `argumentInfo` members have no effect on the outcome, while too few or if one of them is null causes AooRE or NRE when the callsite's target is invoked. Other operation factories will throw NRE if an `argumentInfo` element is null. Excessive infos here are likewise harmless, and potentially even useful, in that a binder like: ```C# var x = CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null); var y = CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null); var binder = Microsoft.CSharp.RuntimeBinder.Binder.InvokeMember(CSharpBinderFlags.None, ""ToString"", new Type[0], GetType(), new[] {x}); ``` Can be used to create delegates representing both the likes of `3.ToString()` and of `3.ToString(""n"")`. (Probably not a good idea, but it works). `UnaryOperation` and `BinaryOperation` could have the validation they assume added. The compat risk is negliable in banning too few arguments as the resulting binder can't be used for anything useful. In banning too many there's a slight risk as that currently works, but it seems unlikely anything hits that path. The other cases can have the NRE on a null info turned into an ANE, but validation of the number of infos would have to wait until at least when the callsite is created, perhaps even until the target is created (not sure yet). Since there's a practical (if questionable) reason why one might deliberately have too many infos, perhaps that should still be allowed." 15612 area-Infrastructure build-managed -release fails when trying to nuget pack Microsoft.Private.CoreFx.NETCoreApp The full log can be found here: https://gist.github.com/jamesqo/2151360517bd4e16981a8d90153bbc48 I've never run into this issue with a debug build yet. 15613 area-System.Linq Calling CallSite.Create() with a null binder is accepted.

This PR speeds things up in both cases if `source` is an array/List/IList, avoiding double interface dispatch and an enumerator allocation. - `source.Where(predicate).Last()` is now recognized in addition to `source.Last(predicate)`, so we don't run the predicate on every item if `source` supports random access. - I also added code to specialize `ilist.Where(predicate)`. It makes sense because we can check for IList at little cost to existing codepaths, and there is already logic in place for `ilist.First(predicate)` and `ilist.Last(predicate)`, so we can implement `ilist.Where(predicate).First()` and `ilist.Where(predicate).Last()` for free.

The service uses a self-signed certificate that is expired. It also uses SSLv3, which, from what I can learn here and on the WCF teams github, is not allowed in corefx. I fully understand the implications and reasoning behind this, but is there no way around this limitation? The company that made the device running the webservice stopped maintaining it years ago. Will .NET Core not allow us to interact with such legacy devices? As I see it, being able to trust a self-signed certificate is no better than allowing SSL.

This is the value that would be returned instead of `default(TSource)` when there are no items in the enumeration There are times when the default value of a given type may be a valid value from the enumeration. If the default value for the enumeration type is valid value, there is not a nice way to determine if the returned values was because the enumeration was empty or if that value was in the enumeration. ## Proposed API change ```C# namespace System.Linq { public static class Enumerable { public static TSource SingleOrDefault(this IEnumerable source, TSource defaultValue); public static TSource SingleOrDefault(this IEnumerable source, Func predicate, TSource defaultValue); public static TSource FirstOrDefault(this IEnumerable source, TSource defaultValue); public static TSource FirstOrDefault(this IEnumerable source, Func predicate, TSource defaultValue); public static TSource LastOrDefault(this IEnumerable source, TSource defaultValue); public static TSource LastOrDefault(this IEnumerable source, Func predicate, TSource defaultValue); } public static class Queryable { public static TSource SingleOrDefault(this IQueryable source, TSource defaultValue); public static TSource SingleOrDefault(this IQueryable source, Func predicate, TSource defaultValue); public static TSource FirstOrDefault(this IQueryable source, TSource defaultValue); public static TSource FirstOrDefault(this IQueryable source, Func predicate, TSource defaultValue); public static TSource LastOrDefault(this IQueryable source, TSource defaultValue); public static TSource LastOrDefault(this IQueryable source, Func predicate, TSource defaultValue); } } ``` ## Updates - Switch from using default parameters to method overloads - Added IQueryable methods as well 15666 area-Infrastructure Mark System.Memory and Unsafe as .NET Core App assemblies.

When adding these checks, I noticed several other problems: (1) On Linux, all connections were silently failing due to the way we were trying to connect. The server was listening on IPv6Loopback, but the client was trying to connect via DNS resolution to ""localhost"". On Windows, ""localhost"" resolves to both IPv6Loopback and IPv4Loopback, so this works. On Linux, it only resolves to IPv4Loopback, thus all client connections fail. Fix is to make the client explicitly connect to IPv6Loopback instead of using the ""localhost"" name. (2) On Windows, the host OS would start rejecting connections at around the 150th connection or so. This seemed to be due to the way the test works; it was connecting and immediately performing lots and lots of sends to the server. The fix is to rework the test to do sends and receives in a slightly less aggressive way, and make sure that the client is processing receives at the same time as sends by spawning separate tasks for them. Also, a couple related changes: (1) Randomly vary the size of the amount of data sent before the client stops sending and waits for all data to be received from the server. (2) Add the SOCKETSTRESS_ITERATIONS env variable to enable longer stress runs. (3) Rework some code to use Tasks, to make the code easier to implement (4) Have just one stress test instead of multiple. (The second variation wasn't really providing any additional coverage anyway.) This stress test should take around 30s to run, compared to 3s previously. " 15680 area-System.Runtime unsigned-correctness in interop structures I have been looking at the recent port #984 of the SerialPort code , and it raises for me a question about the use of unsigned types in interop signatures. For example, the native `COMMTIMEOUTS` structure contains 5 `DWORDS` (https://msdn.microsoft.com/en-us/library/windows/desktop/aa363190.aspx). However, in interop/windows/kernel32/interop.COMMTIMEOUTS.cs, it has 5 ints (this is how it came from the original netfx source). A corollary of this is that we end up with `MAXDWORD` being an defined as `const int = -1`, where it was originally `0xffffffff`. Clearly the p/invoke marshalling doesn't care whether a 32-bit number is signed or unsigned, but it seems to me that one should, in general, try to make p/invoke signatures, etc. match window.h as closely as possible. I don't see anything in the interop guidelines or previous issues about this - is there some policy against unsigned types in interop signatures? Or is this some kind of historical 'don't upset VB with unsigned types' sort of thing?

The closet thing we have today is a `SynchronizationContext` but it's really not appropriate for this. There's also a TaskScheduler but that's about scheduling tasks not arbitrary callbacks. ```C# public interface IScheduler { void Run(Action action); } ``` Not sure what other options we'd need here. this is similar to Java's executor https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/Executor.html. /cc @stephentoub **EDIT: Current proposal** ```C# public interface IScheduler { void Schedule(Action action, object state); } ``` ## Proposed API implemenations **Scheduler** ```C# public abstract class Scheduler : IScheduler { public static IScheduler Default => ThreadPool.Global; public static IScheduler Inline { get; } public abstract void Schedule(Action action, object state); } ``` The scheduler base class just has the default inline scheduler which runs actions inline. There are concerns about stack diving here but it's required for cases where the consumer wants to stay on the caller's thread. **ThreadPool** ```C# public class ThreadPool { public static IScheduler Local { get; } // QueueUserWorkItem (preferLocal:true) public static IScheduler Global { get; } // QueueUserWorkItem (preferLocal:false) } ``` Here we're exposing 2 schedulers from the ThreadPool type. These map to QueueUserWorkItem with various arguments. **SynchronizationContext** ```C# public class SynchronizationContext : IScheduler { public void Schedule(Action action, object state) { Post(new SendOrPostCallback(action), state); } } ``` Exposing the SynchronizationContext as an IScheduler would call Post on the sync context. Since most of the ""dispatchers"" in .NET already implement a sync context (WPF, System.Web, WinForms, UWP, Xamarin etc) this would be the way to bridge the existing tech with this new interface. **TaskScheduler** It should be possible to run Task continuations on any arbitrary IScheduler. We should be able to convert use any IScheduler as a TaskScheduler. This means any thing that uses an TaskScheduler today would just work with the IScheduler via a simple factory. ```C# public class TaskScheduler { public static TaskScheduler CreateFromScheduler(IScheduler scheduler); } ``` ## Potential APIs Consumers Once we have the above types exposed we can start looking at places where using a scheduler might be beneficial. Generally, we can look at places that call directly into QueueUserWorkItem and determine if it makes sense to allow callers to specify which IScheduler should be used instead. More specifically, here are some places it might be useful (we'd of course need to dig into the details more). **SocketAsyncEventArgs** SocketAsyncEventArgs has a callback that executes whenever any IO operation completes (read/write/connect/accept). Currently the thread that callback runs on is either a thread pool thread (in the linux case) or the IOCP completion thread on windows. There are some cases where the calling code wants fine grain control over where continuations run to avoid unnecessary context switches. In these cases it would be ideal if the SocketAsyncEventArgs exposed an IScheduler property that determined where completions ran. ```C# public class SocketAsyncEventArgs { public IScheduler Scheduler { get; set; } } ``` This would allow callers to specify where continuations should run (it could even be OS specific). **Timer** Timer callbacks are always scheduled on threadpool threads. Adding a scheduler would allow using the timer API but would also allow callers to control where callbacks execute. ```C# public Timer(TimerCallback callback, object state, int dueTime, int period, IScheduler scheduler); public Timer(TimerCallback callback, object state, long dueTime, long period, IScheduler scheduler); public Timer(TimerCallback callback, object state, TimeSpan dueTime, TimeSpan period, IScheduler scheduler); public Timer(TimerCallback callback, object state, uint dueTime, uint period, IScheduler scheduler); ``` **Task continuations** Running task continuations on specific threads when using async/await syntax today isn't possible without changing the current task scheduler (AFAIK). Ideally you would be able to do something like: ```C# await task.ContinueOn(scheduler); ``` Today Task has very specific knowledge about the SynchronizationContext capturing because it's the most common scenario. There are scenarios where the caller whats to continue on another scheduler or TaskScheduler and wants to specify that at the point of the await. ```C# public class Task { public TaskAwaiter ContinueOn(TaskScheduler scheduler); } ``` **CancellationToken** CancellationTokens allow for the registration of callbacks that execute of callbacks upon cancellation. A scheduler can be specified to determine where these callbacks should run. This would be more efficient than scheduling the call to Cancel to run on another thread since doing if efficiently requires knowledge that callbacks are registered (see https://github.com/dotnet/corefx/issues/23716 for a related issue). There could be an overload of cancel that takes an IScheduler. ```C# public class CancellationTokenSource { public void Cancel(IScheduler scheduler); } ```" 15688 area-System.Security Access violation using X509Chain in netcoreapp1.1 "When upgrading a project from `netcoreapp1.0` to `netcoreapp1.1` we found that we were hard crashing the CLR.

You may wonder why that's needed when you already have the value when you might want to retrieve it. Well, that's not always true depending on the `Comparer` you're using as a value may evaluate to being contained within the set but is not strictly equal to the value stored in the set. ## Proposed API ```diff namespace System.Collections.Generic { public partial class HashSet { + public bool TryGetValue(T equalValue, out T actualValue); } public partial class SortedSet { + public bool TryGetValue(T equalValue, out T actualValue); } } ``` ## Rationale and Usage My use case is sometimes I want to create a case-insensitive `string` mapping to the actual `string` value. So for example instead of having to use a `Dictionary` for the mapping as below ```c# var dictionary = new Dictionary(StringComparer.OrdinalIgnoreCase); dictionary[""A""] = ""A""; string value = ""a""; string actualValue; if (dictionary.TryGetValue(value, out actualValue)) { Assert.AreEqual(""A"", actualValue); } ``` I could use a `HashSet` like this ```c# var hashSet = new HashSet(StringComparer.OrdinalIgnoreCase) { ""A"" }; string value = ""a""; string actualValue; if (hashSet.TryGetValue(value, out actualValue)) { Assert.AreEqual(""A"", actualValue); } ``` With this implemented users would save on memory usage, would be able to use set operations, and be able to populate the collection more easily. Other possible use cases (from discussion below) - object pool, such as simple string interning - save overhead of the key in a dictionary, when the value knows its own key ## API Details * `TryGetValue` returns an indication if the `HashSet` contains the `equalValue` and the output parameter `actualValue` contains the `HashSet`'s value that equals `equalValue` with the set `Comparer` if contained in the `HashSet` otherwise the default value of `T`. ## Updates * Formalized request * Removed getter indexer" 15692 area-Meta Add P/Invoke notes Adds detailed notes and guidelines for defining P/Invokes. @willdean, @tijoytom, @mellinoe, @stephentoub, @jkotas 15693 area-System.IO Get rid of System.IO.Compression OOB - .NET Standard 2.0 should forward to Desktop Framework The cost of shipping OOB for Desktop is very high and we have burned ourselves (System.Net.Http).

This PR changes the tests to only send once; I will measure the test impact over several days and determine whether to keep it like this, or if new failures start occurring due to packet loss we'll need to refactor the tests in some manner to accommodate multiple sends without side effecting other tests running in parallel. Also I'm not sure if packet loss should ever occur on loopback \ localhost, assuming that various send\receive buffers do not get overloaded when our tests run, and in that case sending multiple times may make the problem worse. I believe the problem is the extra sends that would normally just get lost actually go to the wrong server if another test running in parallel happens to create a server with the same port number. UDP is connectionless so the client doesn't know if the original server has been closed. This causes things like expected timeouts not occurring because a receive succeeds when there shouldn't be a client sending (https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs#L557) or other failures because received messages are coming from the wrong client(https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs#L2347) Here's some examples of recent test failures affected by this issue (roughly 1 per day on CI runs): ```` Assert.Throws() Failure\nExpected: typeof(System.Net.Sockets.SocketException)\nActual: (No exception was thrown) at System.Net.Sockets.Tests.DualModeConnectAsync.ConnectAsyncV4IPEndPointToV6Host_Fails() in /mnt/j/workspace/dotnet_corefx/master/ubuntu16.10_debug/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 516 Assert.Throws() Failure\nExpected: typeof(System.TimeoutException)\nActual: typeof(Xunit.Sdk.EqualException): Assert.Equal() Failure\nExpected: ::1\nActual: ::ffff:127.0.0.1 at System.Net.Sockets.Tests.DualModeConnectionlessReceiveMessageFrom.ReceiveMessageFromAsync_Helper(IPAddress listenOn, IPAddress connectTo, Boolean expectedToTimeout) in /mnt/resource/j/workspace/dotnet_corefx/master/opensuse42.1_release/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 2347 Assert.Throws() Failure\nExpected: typeof(System.Net.Sockets.SocketException)\nActual: typeof(Xunit.Sdk.ThrowsException): Assert.Throws() Failure\nExpected: typeof(System.Exception)\nActual: (No exception was thrown) at System.Net.Sockets.Tests.DualModeConnectionlessReceiveMessageFrom.ReceiveMessageFrom_Helper(IPAddress listenOn, IPAddress connectTo, Boolean expectedToTimeout) in /mnt/j/workspace/dotnet_corefx/master/ubuntu14.04_debug/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 1988 at System.Net.Sockets.Tests.DualModeConnectionlessReceiveMessageFrom.b__13_0() in /mnt/j/workspace/dotnet_corefx/master/ubuntu14.04_debug/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 1946 Assert.Throws() Failure\nExpected: typeof(System.Net.Sockets.SocketException)\nActual: typeof(Xunit.Sdk.EqualException): Assert.Equal() Failure\nExpected: ::1\nActual: ::ffff:127.0.0.1 at System.Net.Sockets.Tests.DualModeBase.ReceiveFrom_Helper(IPAddress listenOn, IPAddress connectTo) in /mnt/j/workspace/dotnet_corefx/master/ubuntu16.10_debug/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 2709 at System.Net.Sockets.Tests.DualModeConnectionlessReceiveFrom.b__6_0() in /mnt/j/workspace/dotnet_corefx/master/ubuntu16.10_debug/src/System.Net.Sockets/tests/FunctionalTests/DualModeSocketTest.cs:line 1401 ```` cc @ianhays cc @Priya91 cc @davidsh cc @ericeil In reference to issue #14519 15699 area-System.Data Porting PR #15146: Fix for slow down in Sql Client Connection Open Copied from original PR.

First change I made was to switch external to use binplacing logic. Let let us have better control over when to copy and where and allowed copying to multiple locations easily. As part of this I binplace both the primary output (if it exist) as well as all copy-local items. Second change was to combine coreclr and NETNative into a common runtime project (thanks @joperezr). This was to enable the following change. Third I fixed ReferenceFromRuntime to use a project reference to the runtime project for src projects, and block its use from tests. This enables us to build multiple configurations at a time that may need different runtime libs without stomping on each other in the runtime path. It also fixes cases where folks might accidentally use ReferenceFromRuntime instead of a project reference. Finally I noticed that the first change caused a bunch of clashing copies to occur. To fix this (which should be general goodness) I disabled copy local for project references for anything that isn't a test project. /cc @weshaggard @tarekgh 15707 area-Infrastructure Linux Crossbuild VSO job should use Docker Exec pattern https://github.com/dotnet/corefx/pull/15695 added a Linux Crossbuild job to the pipebuild - defined here (https://github.com/dotnet/corefx/blob/master/buildpipeline/DotNet-CoreFx-Trusted-Linux-Crossbuild.json).

However, the class does not possess a way to copy directories from one location to another. If a user wants to copy directories, he/she would have to write their own method to create a directory in the new location and call `File.Copy()` for each file in the source directory. ## Rationale and Usage The `File` class has both `Copy()` and `Move()` methods; however, the `Directory` class only has a `Move()`. Conceptually, a file and a directory are very similar: you can move or copy either of them across your file system. There are many users who [desire](https://stackoverflow.com/questions/627504/what-is-the-best-way-to-recursively-copy-contents-in-c) this feature and there is also an instructive [MSDN article](https://msdn.microsoft.com/en-us/library/bb762914(v=vs.110).aspx) outlining how to copy directories. It will be very convenient for users to simply call a `Copy()` method such as, ```csharp string SourceDirectory = @""C:\sourcefolder""; string DestinationDirectory = @""C:\destinationfolder""; Directory.Copy(SourceDirectory, DestinationDirectory); ``` Further, users will only need to pass in a string without needing to create `DirectoryInfo` so that the parameters are easy to use. ## Proposed API ```csharp public void Copy(string sourceDirName, string destDirName) { DirectoryInfo sourceDirectory = new DirectoryInfo(sourceDirName); DirectoryInfo destinationDirectory = new DirectoryInfo(destDirName); if (!Directory.Exists(target.FullName)) { Directory.CreateDirectory(target.FullName); } //copy all the files into the new directory foreach (FileInfo file in sourceDirectory.GetFiles()) { file.CopyTo(Path.Combine(target.ToString(), file.Name), true); } //copy all the sub directories using recursion foreach (DirectoryInfo subDirectory in sourceDirectory.GetDirectories()) { DirectoryInfo nextTargetDir = destinationDirectory.CreateSubdirectory(subDirectory.Name); Directory.Copy(subDirectory.FullName, nextTargetDir.FullName); } } ```" 15709 area-System.Diagnostics Console app uses 100% cpu when is ran by Process.Start with redirecting input/output dotnet core version: 1.0.2 OS: Windows 10 or Ubuntu 16.04 x64 How to replicate the issue: 1.

In the case following a `MoveNext()` that has returned `false` or an action has made the source collection consider itself to have been mutated, then `IEnumerator.Current` is undefined while `IEnumerator.Current` is documented as always throwing `InvalidOperationException`. This puts a greater implementation burden on the base interface than the derived one. It's also not what happens in practice, for while some implementations follow the more restrictive practice (and at least one actually treats them differently in this way) a great many follow the documentation for `IEnumerator.Current` when it comes to `IEnumerator.Current`, including the iterators produced by `yield`: ```C# private IEnumerable TestEn() { yield break; } public static Main() { IEnumerator en = TestEn().GetEnumerator(); en.MoveNext(); Console.WriteLine(en.Current); // 0 } ``` Such cases have existed since .NET 2.0 (indeed a great many in 1.1 were breaking the tighter rule anyway) so the requirement for throwing IOE clearly isn't necessary. I think the documentation for `IEnumerator.Current` should be updated to match the reality, which is that it should be the same as that for `IEnumerator.Current` in this regard. 15719 area-System.Linq Allow TryExpression inside a filter? Compiling a `TryExpression` that is inside the `Filter` expression of a `CatchBlock` of another `TryExpression` throws with the IL compiler (the interpreter has no problem with it). This is reasonable since if it produced such IL it would be unverifiable. It is however a limit on composability; a method producing `bool`-typed expressions may in good faith use a `TryExpression` within it while a method producing `CatchBlock`s may in good faith use such an expression in a filter. The failure comes from the combination of two reasonable operations. Branching to outside of the filter won't work, as that is also unverifiable. Emitting a method for the closure of the filter expression and locals it uses, and calling that method as a new filter expression **would** work. 15724 area-Meta Remove Comments with (#15374) Hi, Submitting the comment clean up for #15374.

As part general logging infrastructure, it is useful to have timestamps. DateTime (using UTC) is a fine way of doing this, (it has 100nsec resolution) however DateTime.UtcNow has poor resolution (16msec). We need a way of getting DateTimes that is more precise. It is very straightforward to implement this using System.Diagnostics.Stopwatch. Thus we recommend adding the following API to it ```c# class System.Diagnostics.Stopwatch { // Computes a more precise UtcNow time. static DateTime UtcNow { get; } } ``` The implementation simply fetches 'DateTIme.UtcNow' and the current stopwatch tick count and uses that to compute the DateTIme when stopwatch ticks started. You can then use a call to Stopwatch.GetTimeStamp() and this start time to compute UtcNow (the current time). I considered putting this API in DateTIme, but decided against it because 1. The implementation naturally depends on Stopwatch. 2. Users of Stopwatch are the natural clients of this API. 3. We would end up with UtcNow and UtcNowPrecise, which feels a bit ugly. 4. DateTime lives in CoreCLR which complicates the implementation if we put it there.

Most types use `conv` instructions but when the value is known to be in the types range (as these are ipso facto being typed as such) this has no effect. Just use `EmitInt` for all values < 32bit size. Since `EmitInt` is now a bit of a misnomer, rename all such methods to `EmitPrimitive`. Use shorter `ldc*` instructions for 64-bit constants when the value will fit within 32 bits, as either a signed or unsigned value. 15798 area-System.Data Enabling diagnostics in the middle of a connection causes NullReferenceException There were test failures due in SqlConnection.Open due to a NullReferenceException. This happens in the following case, 1. Do not enable statistics on SqlConnection and do not enable any Diagnostic listeners listening to the Command Diagnostics, and open a connection. 2. The diagnostics are enabled just during the `TryOpen` call in SqlConnection. (This is a matter of timing, but is easily reproducible in many CI runs. ) While trying to add statistics, the SqlConnection throws a NullReferenceException while de-referencing `_statistics` which was never initialized. The fix is to check for `Statistics` property before adding statistics data. This is a pattern I found the SqlConnection code and used it to fix this regression. There are two test changes 1. Enable the SqlConnectionBasicTests by removing the [ActiveIssue] tag. 2. I had to move the Diagnostic test to the ManualTest project. This is because the Diagnostic Tests should not be executed in parallel with other SqlConnection Open and manual tests are executed serially. The diagnostics tests will still be executed automatically in the CI. The diagnostics test can get a null diagnostic if another SqlConnection test is running in parallel and its intended to check the diagnostics coming out of the behavior of the tests that its executing and not other tests. cc @corivera @stephentoub Fixes #14017 15805 area-Meta Marking code as unchecked (pt 1) Marking code that may intentionally lead to over or underflows with unchecked in preparation of turning on CheckForOverflowUnderflow for all projects (issue #3140) 15806 area-System.Linq S.L.Expressions ignores scale compiling small constant decimals `decimal` scaling means that there are sometimes when `0m` is treated differently to `0.00m`, e.g. when `ToString()` is called.

} public static int BinarySearch( this ReadOnlySpan span, TComparable comparable) where TComparable : IComparable { throw null; } public static int BinarySearch( this ReadOnlySpan span, T value, TComparer comparer) where TComparer : IComparer { throw null; } // NOTE: Due to the less-than-ideal generic type inference // in the face of implicit conversions, // we need the overloads taking Span. // These simply forward to ReadOnlySpanExtensions. // Convenience overload public static int BinarySearch( this Span span, IComparable comparable) { return BinarySearch>(span, comparable); } public static int BinarySearch( this Span span, TComparable comparable) where TComparable : IComparable { return BinarySearch((ReadOnlySpan)span, comparable); } public static int BinarySearch( this Span span, T value, TComparer comparer) where TComparer : IComparer { return BinarySearch((ReadOnlySpan)span, value, comparer); } } ``` ### Rationale and Usage Provide a safe yet fast way of binary searching of any type of contiguous memory; managed or unmanaged. ```csharp public static class UsageForInt { struct InlineableComparer : IComparer { [MethodImpl(MethodImplOptions.AggressiveInlining)] public int Compare(int a, int b) { if (a == b) { return 0; } if (a < b) { return -1; } return 1; } } struct InlineableComparable : IComparable { int m_value; public InlineableComparable(int value) { m_value = value; } [MethodImpl(MethodImplOptions.AggressiveInlining)] public int CompareTo(int other) { if (m_value == other) { return 0; } if (m_value < other) { return -1; } return 1; } } public static void SpanBinarySearch() { var span = new Span(); //span.Sort(); int valueToFind = 42; // Direct value var index = span.BinarySearch(valueToFind); // Inlineable struct comparer var comparer = new InlineableComparer(); index = span.BinarySearch(valueToFind, comparer); // Inlineable struct comparable var comparable = new InlineableComparable(valueToFind); index = span.BinarySearch(comparable); } public static void ReadOnlySpanBinarySearch() { ReadOnlySpan span = new Span(); //span.Sort(); int valueToFind = 42; // Direct value var index = span.BinarySearch(valueToFind); // Inlineable struct comparer var comparer = new InlineableComparer(); index = span.BinarySearch(valueToFind, comparer); // Inlineable struct comparable var comparable = new InlineableComparable(valueToFind); index = span.BinarySearch(comparable); } } public static class UsageForCompound { struct Compound { public float FeatureValue; public int FeatureIndex; public object Payload; } struct InlineableFeatureValueComparer : IComparer { [MethodImpl(MethodImplOptions.AggressiveInlining)] public int Compare(Compound a, Compound b) { if (a.FeatureValue == b.FeatureValue) { return 0; } if (a.FeatureValue < b.FeatureValue) { return -1; } return 1; } } struct InlineableFeatureComparable : IComparable { readonly float m_featureValue; public InlineableFeatureComparable(float featureValue) { m_featureValue = featureValue; } [MethodImpl(MethodImplOptions.AggressiveInlining)] public int CompareTo(Compound other) { if (m_featureValue == other.FeatureIndex) { return 0; } if (m_featureValue < other.FeatureIndex) { return -1; } return 1; } } public static void SpanBinarySearch() { var span = new Span(); //span.Sort(new InlineableFeatureValueComparer()); float featureValueToFind = 1.234f; // Inlineable struct comparer var comparer = new InlineableFeatureValueComparer(); // Less than ideal for compound, which is reason for comparable overload var compound = new Compound(){ FeatureValue = featureValueToFind }; var index = span.BinarySearch(compound, comparer); // Inlineable struct comparable (easier to use for compounded type) var comparable = new InlineableFeatureComparable(featureValueToFind); index = span.BinarySearch(comparable); } public static void ReadOnlySpanBinarySearch() { ReadOnlySpan span = new Span(); //span.Sort(new InlineableFeatureValueComparer()); float featureValueToFind = 1.234f; // Inlineable struct comparer var comparer = new InlineableFeatureValueComparer(); // Less than ideal for compound, which is reason for comparable overload var compound = new Compound(){ FeatureValue = featureValueToFind }; var index = span.BinarySearch(compound, comparer); // Inlineable struct comparable (easier to use for compounded type) var comparable = new InlineableFeatureComparable(featureValueToFind); index = span.BinarySearch(comparable); } } ``` The argumentation for adding this is: * To increase the efficiency of code doing binary searching and prevent people from reinventing the wheel. * Allow binary searching on contiguous memory of any kind. ### Open Questions An important question regarding this proposal is whether the pattern with generic parameter `TComparer` (e.g. constrained to `where TComparer : IComparer`) or `TComparable` (constrained to `where TComparable : IComparable`) is a pattern that can be approved. This pattern allows for inlineable comparables/comparers at the cost of increased code size, if no value type comparables/comparers are used, there should be no difference. This pattern is also used in the proposal for `Sort` in https://github.com/dotnet/corefx/issues/15329, that has been approved. Another open question is whether the overload taking `IComparable` is necessary. The API relies on being able to depend upon `System.Collections.Generic`, could this be an issue? @karelz @jkotas @KrzysztofCwalina @jamesqo ### Updates UPDATE 1: Add link to Sort and point on the pattern used. UPDATE 2: Add IComparable overloads for convenience as suggested by @jkotas UPDATE 3: Combine all extensions into `SpanExtensions`. ### Existing Sort APIs A non-exhaustive list of existing binary search APIs is given below for comparison. #### `Array.BinarySearch` Static Methods Found in [ref/System.Runtime.cs](https://github.com/dotnet/corefx/blob/master/src/System.Runtime/ref/System.Runtime.cs) ```csharp public static int BinarySearch(System.Array array, int index, int length, object value) { throw null; } public static int BinarySearch(System.Array array, int index, int length, object value, System.Collections.IComparer comparer) { throw null; } public static int BinarySearch(System.Array array, object value) { throw null; } public static int BinarySearch(System.Array array, object value, System.Collections.IComparer comparer) { throw null; } public static int BinarySearch(T[] array, T value) { throw null; } public static int BinarySearch(T[] array, T value, System.Collections.Generic.IComparer comparer) { throw null; } public static int BinarySearch(T[] array, int index, int length, T value) { throw null; } public static int BinarySearch(T[] array, int index, int length, T value, System.Collections.Generic.IComparer comparer) { throw null; } ``` #### `List.BinarySearch` Member Methods Found in [ref/System.Collections.cs](https://github.com/dotnet/corefx/blob/master/src/System.Collections/ref/System.Collections.cs) ```csharp public partial class List : System.Collections.Generic.ICollection, System.Collections.Generic.IEnumerable, System.Collections.Generic.IList, System.Collections.Generic.IReadOnlyCollection, System.Collections.Generic.IReadOnlyList, System.Collections.ICollection, System.Collections.IEnumerable, System.Collections.IList { public int BinarySearch(T item) { throw null; } public int BinarySearch(T item, System.Collections.Generic.IComparer comparer) { throw null; } public int BinarySearch(int index, int count, T item, System.Collections.Generic.IComparer comparer) { throw null; } } ``` 15821 area-System.Linq Cleanup unecessary forwarding helpers in Expression 15823 area-System.Runtime XML API documentation not available for System.ValueTuple - Reference System.ValueTuple NuGet package (version 4.3.0) - Use APIs **EXPECTED**: API documentation shows up in intellisense **ACTUAL**: No API documentation shown It looks like this is an issue with the package authoring, next to `System.ValueTuple.dll`, it has a file named `.xml` instead of `System.ValueTuple.xml`. @weshaggard @ericstj @stephentoub 15825 area-System.Globalization Comparer.Default sort order different on Linux/OSX than Windows or Mono "Found this while investigating #15445 (**edit:** see https://github.com/dotnet/corefx/issues/15825#issuecomment-277564885 where it looks like `Comparer.Default` is the underlying culprit): ```csharp using System; using System.Linq; namespace ConsoleApp { class Program { static void Main(string[] args) { var keys = new string[] { ""M:System.UriBuilder.#ctor"", ""M:System.UriBuilder.#ctor(System.String)"", ""M:System.UriBuilder.#ctor(System.Uri)"", ""M:System.UriBuilder.#ctor(System.String,System.String)"", ""M:System.UriBuilder.#ctor(System.String,System.String,System.Int32)"", ""M:System.UriBuilder.#ctor(System.String,System.String,System.Int32,System.String)"", ""M:System.UriBuilder.#ctor(System.String,System.String,System.Int32,System.String,System.String)"" }; var items = new int[7] { 0, 1, 2, 3, 4, 5, 6 }; var ordered = items.OrderBy(s => keys[s]).ToList(); Console.WriteLine(String.Join(Environment.NewLine, ordered)); } } } ``` This prints the following on OSX/Linux: ``` 0 6 5 4 3 1 2 ``` However, on Windows .NET Core or .NET Framework, as well as Mono on OSX/Linux it prints: ``` 0 1 3 4 5 6 2 ``` I suspected a difference due to culture/language, but forcing CurrentCulture to ""en-US"" didn't change the output.

Sin and Cos perf is improved by only making one call to Math.Exp to compute the required real hyperbolic trig functions. (Hopefully the JIT compiler is smart enough to make a single FPU call for the required real sin and cos, but that's not something I can force. It would be nice if there were a Math.SinAndCos method that explicitly forced this.) Tan perf is similiarly improved, and, more importantly, modified to correctly handle the large region (all |z.Im| larger than about 710) for which Sin and Cos overflow but Tan doesn't. Sinh, Cosh, and Tanh are modified to call Sin, Cos, and Tan, so that all current and future improvements to the complex trig functions automatically feed into the complex hyperbolic trig functions. Several test cases for Tan and Tanh involving large arguments needed to be changed. Some of the previous test assertions were simply assertions of the previous bad behavior, e.g. demanding NaN for Tanh(big real) instead of 1. These have been changed to assert the new, mathematically correct behavior. Some of the previous test assertions are inappropriate given the bad behavior of the .NET real trig functions, e.g. demanding Tan(x + 0.0 i) = Math.Sin(x) / Math.Cos(x) for big x, even though Math.Sin(x) and Math.Cos(x) return incorrect values for big x. I have simply removed these tests. I have added attributes to skip all the changed tests for NetFx; there are still many shared test assertions for not-big arguments that are satisfied by both new and old code. (The fix for Asin and Acos come next. I wanted to get these simple fixes for the basic trig functions in before submitting a complicated one for the inverse trig functions.) 15837 area-System.Collections "Test: System.Collections.Concurrent.Tests.ConcurrentQueueTests/ManyConcurrentAddsTakes_CollectionRemainsConsistent(seconds: 1) failed with ""System.OutOfMemoryException""" Opened on behalf of @Jiayili1 The test `System.Collections.Concurrent.Tests.ConcurrentQueueTests/ManyConcurrentAddsTakes_CollectionRemainsConsistent(seconds: 1)` has failed.

"I'm trying to figure out some inconsistencies in how `HttpClient` handles URLs. I have the following test code: ```C# public async Task TestHttpClient() { var baseUrl = ""https://api.twitter.com/1.1/search/tweets.json""; //var query = ""(cafe OR boulangerie)""; var query = ""(café OR boulangerie)""; var url = baseUrl + $""?q={Uri.EscapeDataString(query)}""; var httpClient = new HttpClient(); var response = await httpClient.GetAsync(url); await response.Content.ReadAsStringAsync(); } ``` The code won't actually work, since we need authentication and other stuff for Twitter searches. But it demonstrates my problem. The variable `url` will have the following value: `https://api.twitter.com/1.1/search/tweets.json?q=%28caf%C3%A9%20OR%20boulangerie%29` However, looking at the request in Fiddler, I can see that what is actually sent is: `https://api.twitter.com/1.1/search/tweets.json?q=(caf%C3%A9%20OR%20boulangerie)` So all of a sudden, the parentheses are no longer encoded. This matters in my case, because I use the encoded query string to calculate a signature that I use to authenticate against twitter. So my signature will have percent encoded parentheses and the request won't, so Twitter throws an error and tells me the authentication fails. What is interesting is that if I send the query with a regular e instead of é then the parentheses are encoded in the request! Like this: `https://api.twitter.com/1.1/search/tweets.json?q=%28cafe%20OR%20boulangerie%29` I suppose this is some kind of bug with `HttpClient`?

I'd be grateful if, in particular, @JeremyKuhne and @karelz could have a look and let me know if I'm completely on the wrong track here before I do dozens more files like this. There are some clear issues emerging already: * There are subtle differences about the way USB serial port adaptors buffer data and handle handshaking which will probably require some test modification to pass - I've got one 'skip' in there at the moment because of this. * The legacy tests were all run in a `return bool` style, which allowed the test function a chance to robustly close ports before returning, which is vital if one test failure isn't going to bleed all over all the other tests. Obviously XUnit throws itself out of the middle of a test, which means that I have had to add a lot of `try / finally` blocks to contain that throw while maintaining a similar code layout to the existing code. In fact, almost every test is going to require the same sort of boilerplate which is rather unattractive. Another approach would be to hoist the ownership of the various `SerialPort` objects out of the test methods into the test class, and then do some defensive clean-up in the `[Teardown]` methods (or whatever the XUnit equivalent is). Or there's probably some `IDisposable` wrapper pattern which would be cleaner - I'm not 100% clear why the disposability of SerialPort isn't exploited here - maybe we should just have all `SerialPort` objects in `using` blocks? Any preferences here? Tagging #15752 15868 area-Infrastructure Remove SUSE 13.2 build Change PB_ arguments so helix build will turn on for 42.1.

In Unix, ports are random while in Windows ports are incremental, thus the issues don't occur in Windows because by the time the ports roll around, the tests will be done. The odds of a port collision causing a Unix failure in a test run is small: say ~1:1,000 test runs fail due to this, but spread across all versions of Unix that are running tests it becomes more common. The proposed fix is to retry once when running under Unix; other options considered were to remove the tests or loop perhaps 3 times (instead of retrying once).

Switch the to using a common DefaultReference notion between targets and eliminated targetingpack.props. Moved the default references for tests into tests.targets. Fixed where we added Private to References because in some cases it wasn't happing because the target that set Private=true was run before all the references were added. This is why we are now setting Reference Private=false in a different target from ProjectReference Private=false because they sometimes need to happen at different times in the target execution. Set _FindDependencies=false to block RAR from trying to automatically add the closure of the primary references as it added automatic references that folks could accidently start depending on and we want to be explicit about our dependencies. This was really noticable once we started auto referencing the netstandard facade which caused everything to get pulled into the reference set. To fix the various build scenarios where we add ProjectReferences automatically we needed a common target to hook on which we now have AddProjectReferencesDynamically target that correctly hooks into the various dependency chains. See comment in targets file for more details. cc @ericstj @mellinoe @joperezr Fixes https://github.com/dotnet/corefx/issues/15847, https://github.com/dotnet/corefx/issues/15744 15919 area-Infrastructure Add standard repo to auto-update scripts for corefx cc @dagood @eerhardt Adding support for https://github.com/dotnet/versions/pull/124#event-950852931 in corefx dependencies. 15921 area-System.Numerics Add hypot, expm1, log1p These are very standard methods used in numerical computing. ``` public static class Math { // Returns sqrt(x^2 + y^2) without overflow/underflow for large/small x, y double Hypot (double x, double y) // Returns e^x -1 without loss of accuracy for small x double Expm1 (double x) // Returns log(1+x) without loss of accuracy for small x double Log1p (double x) } ``` They appear, with exactly these names, in the Java Math class and Boost and GSL libraries, in many other mathematical libraries, and in many articles in the numerical computing literature. Naming: The names are somewhat cryptic. .NET coding guidelines would probably favor ExpMinusOne over Expm1, etc. On the other hand, the names are quite standardized. We would need to decide whether conforming to the expectations of advanced users or giving a better hint at meaning to less advanced users is more important. Location: The obvious place is System.Math, but: (i) this class is already quite a jumble, (ii) it mostly follows math.h of the C standard library, which does not contain these functions, and (iii) the presence of these functions might baffle naive users. One possibility would be to add a MoreMath or AdvancedMath static class in the System.Numerics namespace, which would also be a natural place for future advanced functions such as erf, Gamma, etc. Domain and Range: The only slightly non-trivial issue here is that Log1p is not defined for x < -1. We would need to decide whether to retutrn NaN or throw ArgumentOutOfRangeException. Implementation and Performance: Implementations are straightforward and well-established. Each can be executed over the entire range with a handfull of flops, making them about as fast as most other standard math functions. 15925 area-System.Net Detect Unix paths on Unix and Dos&Unc paths on Windows Fixes https://github.com/dotnet/corefx/issues/1745 \CC @stephentoub TODO: - [x] Equals test HashCode check https://github.com/dotnet/corefx/pull/15925/commits/4a7ce12fb744f324b8b6ebcf7e2eb6590f3c7b05 15926 area-System.Net "Dns.GetHostEntry(""IPv6_string"") does not work anymore in Linux environment."

For a single multiplication, a 4 flop additional cost is trivial. But in large operations on Complex matrices, where Complex arithmetic operations occur in rapid succession within tight O(N^3) loops, this can cut the overall time for a Complex matrix operation from 3 hours to 1 hour. The operations to implement are as follows: ```C# public struct Complex { // Mixed double/Complex multiplication 6 flops -> 2 flops public static Complex operator* (double a, Complex b) public static Complex operator* (Complex a, double b) // Complex / double division 9 flops -> 2 flops // This is the largest efficiency gain. public static Complex operator/ (Complex a, double b) // double / Complex division 9 flops -> 6 flops // This is the least worthwhile and could be skipped. public static Complex operator/ (double a, Complex b) // Mixed double/Complex addition 2 flops -> 1 flop public static Complex operator+ (double a, Complex b) public static Complex operator+ (Complex a, double b) // Mixed double/Complex subtraction 2 flops -> 1 flop public static Complex operator- (double a, Complex b) public static Complex operator- (Complex a, double b) // Also 7- 8 static helper methods Multiply, Divide, Add, Subtract public static Complex Add (double left, Complex right) public static Complex Add(Complex left, double right) public static Complex Subtract(double left, Complex right) public static Complex Subtract(Complex left, double right) public static Complex Multiply(double left, Complex right) public static Complex Multiply(Complex left, double right) public static Complex Divide(Complex left, double right) } ``` The implementations are straightforward, with the the exception of double / Complex, which faces the same cancellation and overflow issues as Complex / Complex. 15930 area-System.Net Test failure in System.Net.NameResolution.Tests.GetHostEntryTest.Dns_GetHostEntryAsync_NoneIPAddress_Fail and The test is currently disabled with label [ActiveIssue(10345)](https://github.com/dotnet/corefx/issues/10345), although the issue has been closed.

Fixes https://github.com/dotnet/corefx/issues/15942 Changes: - Remove 2 iterators from `Concat` that specialize for ICollections. Instead of having different iterators, set a flag on the iterator if all inputs so far have been ICollections. This allows us to determine in constant time whether we can get the count cheaply and preallocate for ToArray/ToList. - This allows us to move the source enumerables into linked list nodes that are of uniform type, `ConcatNIterator`. Previously, we had to typecast every time we crossed a node. - Implement `GetCount` and `ToArray` in the derived classes rather than the base to avoid virtual calls and improve time complexity. - Avoid walking the linked list quadratically for `GetCount`, since we don't need to sum the counts in order. - Remove unnecessary virtual calls to `GetEnumerable` for 1 Concat followed by `ToArray`. - Make 1 Concat followed by `Count` cheap if the both of the concatees' counts can be gotten cheaply. - Add a `ReserveOrAdd` method to `SparseArrayBuilder` which either reserves space for the enumerable if its count can be predetermined, or eagerly adds it otherwise. This saves quite a few lines of code. **Performance tests:** [memory leak reduction](https://gist.github.com/jamesqo/c8ccc43c2e9a7b8bb35c6cc6bebeb9ec) / [regressions from this change](https://gist.github.com/jamesqo/bde594c796e2c07117f77e88239a2c40) Need to be updated. /cc @JonHanna @stephentoub @VSadov 15944 area-Infrastructure Android: Removed unused WITH_LLDB_* defines Synchronous toolchain.cmake for armel with CoreCLR and removed unused WITH_LLDB_* defines Related issue: https://github.com/dotnet/corefx/pull/15882, https://github.com/dotnet/coreclr/pull/9409 15946 area-System.Linq Reuse more IL locals in S.L.Expressions Cache more `LocalBuilder`s after use, reducing the number of locals emitted in produced methods, and reducing allocations in creating them.

I installed msbuild manually from a stand-alone package (nobody told me to, but it seemed sensible).anThen I copied the entire corefx tree to the machine and run build.cmd, and it says this: ``` Error: Visual Studio 2015 required. Please see https://github.com/dotnet/corefx/blob/master/Documentation/pro ject-docs/developer-guide.md for build instructions. ``` I'm sceptical that VS2015 is actually required (that's not the issue however), but I'm 100% sure that the document that which is referred to doesn't answer the question - it doesn't mention VS2015 at all, and only mentions VS in passing about debugging something. Personally I think these kind of newbie-only paper cuts are worth fixing. 15956 area-Meta Enable tests to compile with netstandard Most of the tests have netstandard configurations and it doesn't compile. the changes here is to fix the configurations and the tests to compile.

Converting data from one form to another is a necessary part of vector algorithms in many areas such as image processing, signal processing, text manipulation, and more. Current SIMD instruction sets expose a lot of functionality for quickly and efficiently converting large chunks of data, but the current interface of `Vector` does not have any support for it. Allowing access to these intrinsics could greatly speed up common algorithms involving data conversion. # Proposed additions All of the additions are on the static `Vector` class, and operate on parameters of type `Vector`. The additions are systematic and straightforward. `Widen` and `Narrow` are provided for type pairs that are half- or double-sized, and `Convert` is provided for same-sized integral-floating point type pairs. ```C# public static partial class Vector { public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static void Widen(Vector source, out Vector dest1, out Vector dest2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector Narrow(Vector source1, Vector source2); public static Vector ConvertToSingle(Vector value); public static Vector ConvertToSingle(Vector value); public static Vector ConvertToDouble(Vector value); public static Vector ConvertToDouble(Vector value); public static Vector ConvertToInt32(Vector value); public static Vector ConvertToUInt32(Vector value); public static Vector ConvertToInt64(Vector value); public static Vector ConvertToUInt64(Vector value); } ``` # Semantics The semantics are simple and uniform. I will use a representative set of methods to explain. ```C# Widen(Vector source, out Vector dest1, out Vector dest2) ``` An input `Vector` called `source` is given. When the method completes, `dest1` contains the lower half of elements in `source`, and `dest2` contains the upper half of elements in `source`. The elements are converted as if they were individually cast from `byte` to `ushort`. ```C# Vector Narrow(Vector source1, Vector source2) ``` Two input `Vector`'s are given. The method returns a single `Vector`. The return value's lower elements are the elements from `source1`, and the upper elements are from `source2`. The elements are converted as if they were individually cast from `ushort` to `byte`. ```C# Vector ConvertToSingle(Vector value) ``` A single `Vector` is given. The method returns a single `Vector` containing the input's elements. The elements are converted as if they were individually cast from `int` to `float`. # Rationale Currently, there is no way to efficiently convert elements residing in `Vector` to a different data type. Directly converting the vector's source data (in a serial manner) is the most efficient way, but that requires your algorithm to break out of ""vector mode"" just to do simple conversion operations. It is also many times slower than we could achieve with proper vector conversion support. Many common algorithms require conversions from one data type to another, so this is currently a large hole in the API. @sivarv @CarolEidt " 15959 area-Serialization Add several tests for XmlSerializer Supporting varied types in SOAP. #15356 @shmao @zhenlan @mconnew 15960 area-System.Reflection Existing reflection APIs should be able to invoke ref-returning methods and return a value "Related to: https://github.com/dotnet/roslyn/issues/8489 The scenario seems to be explicitly forbidden. Possibly due to ref returning methods not being common in the past. Note that this issue does not ask for a new API that would allow returning a `ref`. This is just about the existing APIs that returns the result as an object. It seems that they should work with ref returning methods by evaluating the target, reading the value indirectly and returning the value as object. ```C# object result1 = inst.RefReturningMethod(); // should be the same as object result2 = inst.GetType().InvokeMember(inst, . . ., ""RefReturningMethod"",. . .); ``` " 15961 area-System.IO SerialPort timeout tests are slow and flaky They don't play well with CI builds and take some time.

So `Tls | Tls12` is an invalid choice. In this change: General: * All OSStatus related exceptions now look up the error message. X509Certificates: * X509Certificate moves to using SecCertificateRef from OpenSSL's X509. * X509 metadata comes from a managed reader after being loaded by Security.framework, due to the significant amount of data that has no public export in Apple's libraries. * Significant code was factored out to be shared by OpenSSL and Apple implementations for X500DistinguishedName and X509Certficate2Collection.Find. * Loading a PFX (or, rather, the private keys from a PFX) via Apple's platform requires importing into a Keychain, and a Keychain requires a file on disk. A temporary keychain is created during cert loading and erased when safe. Like the perphemeral key load on Windows this can leak files due to abnormal program termination.

When you call `reader.GetInt64(i)` to get a big number it'll work great, but if you try to do `reader.GetValue(i)` then it'll fail with and `Unknown SQL type` exception. Given the inner working of SQLite, I'd say this is expected. The real issue here is that `reader.GetInt64(i)` works fine but `reader.GetFieldValue(i)` throws the same exception as `GetValue` (since it's just a cast as seen [here](https://github.com/dotnet/corefx/blob/c5c75db7c00047d603522fd6e21f350099e09bbb/src/System.Data.Common/src/System/Data/Common/DbDataReader.cs#L156)). This behavior is really unexpected from APIs with (presumably) the same purpose. Since this is a newer API added in .NET 4.5, it's a shame that it works worse than the old one. Maybe we can add special cases for the types we already support (e.g. `GetInt64`)?

To do this we need incoming requests to be tagged with an ID (and potentially other information), and have this information 'flow' through (be available) to all code run in response to that request and in particular allow this information to be propagated to any outgoing requests. #15023 Implements this approach and involves additional costs such as maintaining Activity.Current and context propagation. To reduce such costs, we want to enable advanced sampling and outgoing requests filtering. DiagnosticSource declares IsEnabled method and allows to filter events based on their names. * For sampling scenario, IsEnabled(string) allows to implement fixed rate or threshold sampling, however sampling may be done based on other properties: request initiator, particular feature, path, specific Id in the Activity.Baggage * For outgoing request filtering, users may need to prevent instrumentation of certain requests based on their URI or other properties. IsEnabled(string) does not allow to efficiently implement such scenarios and we propose to add IsEnabled with additional context. # Proposed API ```C# public abstract partial class DiagnosticSource { public virtual bool IsEnabled(string name, object arg1, object arg2 = null) { return IsEnabled(name); } } public partial class DiagnosticListener { public override bool IsEnabled(string name, object arg1, object arg2 = null); public virtual IDisposable Subscribe(IObserver> observer, Func isEnabled) } ``` # Usage ```C# //This code represents web service hosting layer that receives incoming http request //See more details about this samples and Activity in #15023 //For the filtering, we want to // 1) Make sure someone listens to the http incoming request events and only if it's true, // create Activity and fill it's baggage and parent id // 2) Let user enable instrumentation based on request and Activity properties. // 3) If user decides to instrument this particular request, we can start Activity and send event public void OnIncomingRequest(DiagnosticListener httpListener, HttpRequest request) { //check if user is interested in such events at all if (httpListener.IsEnabled(""Http_In"")) { var activity = new Activity(""Http_In""); //parse request headers and add baggage to Activity activity.SetParentId(request.headers[""x-ms-request-id""]) foreach (var header in context.Request.Headers) if (header.Key.StartsWith(""x-ms-baggage-"") activity.AddBaggage(header.Key, header.Value); //let user decide if he wants this request and activity to be sampled if (httpListener.IsEnabled(""Http_In"", request, activity)) httpListener.StartActivity(activity); //... process request and stop activity } } //This code demonstrates how user can subscribe to events with advanced filtering based on request and activity properties public void Startup() { DiagnosticListener.AllListeners.Subscribe(delegate (DiagnosticListener listener) { var predicate = (string name, object requestObj, object activityObj) => { //check for event name if (name == ""Http_In"") { var request = (HttpRequest)requestObj; //filter out some unintersting events if (request != null && request.Method == ""OPTIONS"") return false; //sample requests based on CorrelationId in the baggage var activity = (Activity)activityObj; if (activity != null) return IsSampledId(activity.GetBaggage(""CorrelationId"")); //note that if no context (request and activity) provided, we return true, //so the first httpListener.IsEnabled(""Http_In"") check will pass return true; } return false; } if (listener.Name == ""System.Net.Http"") { listener.Subscribe(delegate (KeyValuePair value, predicate) { Console.WriteLine(""Event: {0} Current Operation: {1} Current ID {2}"", value.Key, {Activity.Current.OperationName}, {Activity.Current.Id}); }); } } } // This code demonstrates that it's still possible to filter events based on their names only public void Startup() { DiagnosticListener.AllListeners.Subscribe(delegate (DiagnosticListener listener) { if (listener.Name == ""System.Net.Http"") { listener.Subscribe(delegate (KeyValuePair value, (name) => name == ""Http_In"") { Console.WriteLine(""Event: {0} Current Operation: {1} Current ID {2}"", value.Key, {Activity.Current.OperationName}, {Activity.Current.Id}); }); } } } ``` @vancem @terrajobst " 15985 area-System.Diagnostics [WIP] Support IsEnabled with addtional arguments #15984 This change introduces IsEnabled(string, object, object) obverload in DiagnosticSource for advanced events filtering based on additional event context.

The inverse cast isn't accepted, and `ConvertChecked` fails on both interpreter and compiler. 15992 area-System.Linq Allow casts between bool-based enums and bool, checked and unchecked Fixes #15991 Remove prohibition on creating bool-enum -> bool conversions. Implement in compiler: Since this is the only acceptable conversion to or from boolean types, catch casts between same underlying types and do nothing, as the values on the stack is unchanged anyway. As well as fixing this case it slightly optimises other enum casts with the same underlying type and is closer to what the C# compiler does. Remove the case introduced in #13518 as it should no longer be hit, and anything doing so is a bug. Implement in interpreter: Duplicate the conversion for `Convert` to that for `ConvertChecked`. Also introduce a check on conversions between same underlying type to optimise such paths similarly to what is done in the compiler, though not applicable when underlying type is the final result. 15996 area-System.Linq S.L.Expressions use short ldind/stind for more types. #11407 changed `EmitLoadValueIndirect` and `EmitStoreValueIndirect` from if-else ladders on type == to a switch on TypeCode. The original if-else ladder skipped many types, presumably trading off the larger IL stream caused by using `ldobj` and `stobj` for a quicker walk through the ladder. Since that advantage doesn't hold for a `switch`, add in the omitted types, and re-order by size to make the completeness clearer. 15997 area-System.Collections Optimize ImmutableQueue.CreateRange If the enumerable supports random access then we can push the items on to the forwards stack in reverse order.

It seems like something happened to framework reflection blocking with e.g. Microsoft.CSharp.dll in the 5.2.2 framework metapackage for UWP apps. I was helping out troubleshooting a UWP failure where the `dynamic` keyword support goo was trying to reflect on the CSharpGetMemberBinder type (a private type in the assembly), and the customer was getting a MissingMetadataException on 5.2.2 metapackage, while things worked fine with the previous metapackage. The key difference seems to be the absence of the attribute. Removing reflection blocking is a breaking change. 16024 area-System.Xml OuterLoop_CentOS7.1_release: Test 'System.Xml.Tests.CReaderTestModule.RunTestCase' failed with 'Xunit.Sdk.EqualException' Failed Test: System.Xml.Tests.CReaderTestModule.TCMaxSettings Detail: https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_centos7.1_release/89/consoleText Message: ~~~ System.Xml.Tests.CReaderTestModule.TCMaxSettings [FAIL] Assert.Equal() Failure Expected: 0 Actual: 38 ~~~ Stack Trace: ~~~ /mnt/resource/j/workspace/dotnet_corefx/master/outerloop_centos7.1_release/src/System.Private.Xml/tests/Readers/ReaderSettings/CReaderTestModule.cs(21,0): at System.Xml.Tests.CReaderTestModule.RunTestCase(Func`1 testCaseGenerator) /mnt/resource/j/workspace/dotnet_corefx/master/outerloop_centos7.1_release/src/System.Private.Xml/tests/Readers/ReaderSettings/CReaderTestModule.cs(27,0): at System.Xml.Tests.CReaderTestModule.RunTest(Func`1 testCaseGenerator) ~~~ Configuration: OuterLoop_Centos7.1_release (build#89) 16025 area-System.Data SqlConnection.ClearAllPools not working when running on Linux "You can repeat this issue by steps: create new Asp.Net Core WebApi Project in VS2015 add Nuget package `""System.Data.SqlClient"": ""4.3.0""` write codes in ValuesController ``` // GET api/values [HttpGet] public IEnumerable Get() { using (var connection = new SqlConnection(""Server=ip;Database=db;User Id=user;Password=pass;"")) { connection.Open(); var cmd = new SqlCommand(""..."", connection); cmd.ExecuteNonQuery(); } return new string[] { ""value1"", ""value2"" }; } // GET api/values/5 [HttpGet(""{id}"")] public string Get(int id) { SqlConnection.ClearAllPools(); return ""value""; } ``` run ""dotnet publish"" and upload files to ubuntu 16.04 server build docker image use this Dockerfile, and run this image ``` FROM microsoft/dotnet:1.0.3-runtime COPY . /app WORKDIR /app EXPOSE 5000 ENV ASPNETCORE_URLS=""http://*:5000"" ENTRYPOINT [""dotnet"", ""WebApplication1.dll""] ``` call this webapi by muilti threads ``` public static void Main(string[] args) { var tasks = new Task[10]; for (var i = 0; i < tasks.Length; i++) { tasks[i] = new Task(()=> { //call http://ip:5000/api/values }); tasks[i].Start(); } Task.WaitAll(tasks); Console.WriteLine(""OK""); Console.ReadLine(); } ``` after test many times, then run “sp_who2” in Sql server, you can see many sleeping connections for db **then you call ""http://ip:5000/api/values/1"", webapi will execute _SqlConnection.ClearAllPools()_ method, but run “sp_who2” in Sql server, you can see those sleeping connections not close** SqlConnection.ClearAllPools() works when webapi running on windows, I have tested dotnet runtime 1.0.3 and 1.1.0.

This PR adds a global setting which allows us to shorten them to a few seconds. These tests don't run as part of CI at present because they require hardware support, so this isn't a CI issue.

Not ready for merging - I just need to see what the CI makes of them. 16033 area-System.IO Some SerialPort tests very sensitive to flow control details This is so that I can ActiveIssue a bunch of failing tests as precisely as possible, and also so that I can get my thoughts straight on this. **tl;dr** A significant number of the legacy SerialPort tests rely on specific traditional hardware behaviour which is not available on the CI or in the future. We need to work around this. **Full Details** A lot of the serial port tests, including some of the ones which run with a single, open, serial port (e.g. on the CI) rely on a particular behaviour of the serial.sys driver / 16550 UART. These tests arrange that hardware flow control is enabled on the port and set to block transmission, and they then write data to the port. Because the flow control is adverse, (and because serial.sys does not rebuffer tx data within itself, nor offer it to the UART when the flow-control prohibits), this causes the data to queue-up on the user-mode side of the serial.sys (i.e. in SerialPort). This allows asynchronous and queue-reporting SerialPort behaviour to be tested - there is a pending write which will not complete as long as the flow control conditions remain the same. In tests where a null modem connection is available, the test can adjust the flow control state using the other port - so it can, for example, delay the start of a transmission but then allow it to complete normally. My feeling is that these tests are, in principle, useful - the conditions that they test are always possible in real life, it's just that they're often fleeting and occur in the middle of large data transfers - being able to create them in 'slow motion' is valuable. **The problem** The difficulty in 2017 is that that genuine serial.sys/16550 setups are dwindling in number - we mostly have several other things: *USB Serial Ports* - These tend to have buffering in the driver, in the USB stack and in the silicon at the far end of the USB cable. Hardware flow control *has* to be carried-out within the silicon, and somehow reflected back up to the user-mode level after everything's backed-up, or by using some hybrid of both blocking up the data *and* sending out of band flow-control status back to the driver to tell it to put the brakes on. My tests with FTDI USB-Serial adaptors didn't give me terribly clear results, but it is clear that they don't instantly block writes when the flow control is adverse. USB-Serial solutions don't have the best reputation for reliability either, although 100% fidelity emulation is impossible anyway. *Virtual Machines* - I'm not clear what the CI hardware/software is, but it appears that we have some kind of virtualised serial port, which probably has some buffering within it. Either way, tests that rely on this blocking behaviour tend to fail on the CI. *Serial cards with fancier UARTS*- If you go out and buy a PCI serial port card in 2017, there's a good chance that it will have some kind of enhanced UART on it, which may well have hardware assistance for flow control - this means that the driver will transfer a certain amount of data to the UART hardware even when the flow control is adverse. **Possible solutions** 1. Probe for this behaviour and then use additional ```ConditionalFact``` qualifiers to disable tests which rely on it. 2. Bigger writes, more relaxed queue detection. A device which is working properly should *eventually* back-up writes if the flow control is adverse. The test will no longer be able to verify that *all* the written data is queued-up (some of it will have gone out to the hardware), but other aspects of the test could complete. It's possible that we might be able to probe at startup for the kind of behaviour we could expect.

The same thing would be true of the instruction list produced by the interpreter. @bartdesmet has already done some work in this regard, but there's a lot more that could be covered, so this issue is to track that. One problem with the few tests of IL generation that already exist is that the expected output includes offset numbers (`IL_0000`,… `IL_001a`,… etc.) which means changes to output requires more manual changing than ideal. E.g. if we had great coverage of constant compilation then #15797 would have needed to not just have the redundant instructions it removed removed from the expected output, but every subsequent instruction to be renumbered. If we'd a lot of tests this would be a lot of manual fixing-up and a lot of irrelevant churn in commits, and potentially a lot of unnecessary conflicts between PRs. A starting point therefore would be to have the IL disassembly in the existing tests closer to hand-written IL where labels are only given when used as targets, so that changes can be more localised. 16070 area-System.Linq Remove offset labels from S.L.Expression test IL dumps Instead of labelling every IL instruction with a label based on its offset, label only those that are targets of breaks, leaves, etc. so that changes to expected IL to match changes in implementation can be more localised only to those directly affected. Clean up some unused code, etc. in the IL printer. Similarly don't include numbers when dumping instruction lists from the interpreter. Contributes to #16068 @VSadov this is a first step toward adding more testing of the produced IL. 16074 area-System.Threading Unexpected exception thrown by WaitHandle.SignalAndWait ``` Expected: typeof(System.Exception) Actual: typeof(System.ApplicationException): Object synchronization method was called from an unsynchronized block of code. ``` 16076 area-System.Console On Mac, Console.ReadLine result includes arrow key presses as '\0's "I found this while porting a toy REPL to .NET Core on Mac.

In most cases the nett result is an expression that will have the same outcome as if the expression had been special-cased to similarly match the C# rules exactly. E.g. the C# rules for adding an `short`-backed `enum` `x` and a `short` `y` would convert both to `int`, add them and then cast the result to the `short`-backed enum. The expression produced casts both to `short`, adds them and casts to the `short`-backed enum. Since in S.L.Expressions the result of `short` addition is a `short` (unlike in C# where they are first promoted to `int`) the final cast means the result is the same either way. Likewise bitwise and comparison operations all have the correct nett result. In the case of addition and subtraction with `byte`- or `sbyte`-based enums however this means the expression produced tries to add `byte` or `sbyte` values, which is not valid in S.L.Expressions, and an `InvalidOperationException` results. Catch the case of lifted enum arithmetic, producing an expression with the correct intermediary casts. Fixes #16028. 16086 area-System.Linq MemberInitExpression.Reduce returns block with undeclared variable Calling `Reduce` method on `MemberInitExpression` result in invalid expression tree (at least can't be compiled), because it uses a temporary variable without declaring it: Calling `Reduce` on tree ``` .New DotVVM.Framework.Tests.Binding.TestViewModel(){ EnumProperty = .Constant(B) } ``` results in: ``` .Block() { $var1 = .New DotVVM.Framework.Tests.Binding.TestViewModel(); $var1.EnumProperty = .Constant(B); $var1 } ``` which can't be compiled, because `$var1` is not declared. Or do I miss something? IMHO it can be fixed by adding a `, new [] { objVar }` to https://github.com/dotnet/corefx/blob/master/src/System.Linq.Expressions/src/System/Linq/Expressions/MemberInitExpression.cs#L82 and https://github.com/dotnet/corefx/blob/master/src/System.Linq.Expressions/src/System/Linq/Expressions/MemberInitExpression.cs#L97 16091 area-System.Linq Fix MemberInitExpression.Reduce and ListInitExpression.Reduce Include the temporary variable used in the `BlockExpression` produced.

They test for the presence of archaic serial port features (5/6 bit data, 1.5 stop bits) which are no longer in general use and are not supported by some of the popular modern USB-Serial devices - so we get test failures there even though there is no fault in SerialPort. 2. They don't improve coverage of SerialPort at all - they merely represent different numbers for it to pass down through to the underlying stack. 3. We have other tests which verify the correct behaviour of SerialPort when the underlying stack rejects values for these parameters that it doesn't like. 4. One of them assumed that a baud rate of 12345 can't be selected, just it doesn't work on the original 16550 hardware (which is a clone of the 8250 in a PC/XT) - there is nothing fundamental which says that a port can't offer that rate, and indeed the USB-Serial solutions often can. I don't consider these tests to have any value, given that we'll have to be able to skip them for people to be able to run the tests against modern hardware anyway *and they offer no additional coverage*. Particularly as we move to a more cross-platform approach, SerialPort's test suite is going to have to be more broadminded about what specific features of serial ports might be available - as it stands, the test suite is second-guessing what features the stack offers, based on a very narrow set of assumptions. With this PR, we now have a complete null-modem test pass using conventional hardware (16550 clone on motherboard as first port, 16c950 on PCI card as second port) - this is a major milestone. We also have much better pass rate on USB-Serial hardware than we did, though it's not 100% yet. **System.IO.Ports.Tests Total: 995, Errors: 0, Failed: 0, Skipped: 0, Time: 1145.502s** 16107 area-Meta Microsoft.NETCore.UniversalWindowsPlatform 5.3.0 makes my appx crashes when deploy from .ps1 "Hi, I have an UWP application which crashes when I deploy it manually from PowerShell **Add-AppDevPackage.ps1** 's script but the same app works fine when I deploy from my **VS2017 latest RC.** I can't attach WinDbg because the app is crashing about 4-6 seconds after the launch.

I thought I could change it to `odbc.2` but it didn't work, so I ended up using `odbc.so.2`. Then: 1. Do we have any document with `DllImport`'s look up conventions? I think it's important to have this if we want anyone to use this feature. 2. Is there any way I can add the version number but also remove the file extension (`.so`) so I can reuse this name on OSX?

This creates some unreliable ""last in wins"" behavior where the last build to succeed will be the one that gets published. In 1.0 and 1.1 folks tried to workaround this by turning off some of the overlapping package builds on non-windows, but this is contrary to the vertical build goals. Those goals drive us to have a reference package produced by all verticals, but we'd really only want to ship the one from Windows since it will be signed. I think we need to look at a way to make this work without adding extra complexity to developer builds, or making the official build different from developer builds. Here's my crack at a suggestion for how this should work. 1. Builds should copy to a leg-specific path in azure. This eliminates the potential for overwriting. 2. During publishing have a precedence for package sources, as follows. a. first prefer windows vertical build legs. b. then prefer windows all non vertical build legs. c. then consider other OS legs. 3. If there is ever an ambiguous choice that should be an error: two legs produce the same package without a clear precedence based winner.

Id has hierarchical structure: /root-id.id1.id2.id2 and generated when activity starts internally. Root node of id (root-id) is common for all activities involved in operation processing, so logging systems may filter logs with Id prefix. However some logging systems may not support prefix-based queries or it may be quite expensive to run them. The standard approach to correlate logs is to write some correlation-id with every record. We expect many customers may want to add such correlation-Id to the Activity.Baggage; which would be redundant since root-id serves the same purpose. We want to provide property to expose root-id and avoid unnecessary baggage usage. # API proposal ```C# public partial class Activity { public string RootId {get; private set} } ``` # Usage ```C# void OnIncomingRequest(DiagnoticListener httpListener, HttpRequest request) { if (httpListener.IsEnabled(""Http_In"") ) { Activity activity = new Activity(""Http_In""); activity.SetParentId(request.Headers[""Request-Id""]); if (httpListener.IsEnabled(""Http_In"", request, activity) ) { httpListener.StartActivity(activity); } } } ... //client code DiagnosticListener.AllListeners.Subscribe(delegate (DiagnosticListener listener) { if (listener.Name == ""Microsoft.AspNetCore"") { listener.Subscribe(delegate (KeyValuePair value) { // In this demo we simply log to the console what things are happening.

(in PR #15900) Therefore when armel host packages are published, we have to update arm32 CI script for armel to use standard options. Related issue is tracked at #16174. @gkhanna79 @jyoungyun 16176 area-System.Data EF Core SqlClient and App Insights What can be the reason for not seeing raw SQL in EF app insights in net core project?

Thanks in advance. 16187 area-System.IO SetCreationTime, SetLastAccessTime, SetLastWriteTime Should not open a new stream to obtain a SafeFileHandle I know that in many cases it is ok to do so, but we found ourself in the case where we need to set file times without closing the actual `FileStream`, and this is possible via Windows API. To do so we had to write **unsafe** code which mimic the functionality of the [existing functions](https://referencesource.microsoft.com/#mscorlib/system/io/file.cs,63bd669b43be5f17,references). (which include rewriting [`System.IO.__Error.WinIOError()`](https://referencesource.microsoft.com/#mscorlib/system/io/file.cs,63bd669b43be5f17), this is obviusly a bad thing, because we have to maintain code wich already exist) This could be extremely more usable and **maintainable** if the framework exposed those methods as `SafeFileHandle` Method/ExtensionMethod. My proposal is to leave those functions unaltered but move the actual implementation in an ipotetic function: `SafeFileHandle.SetFileTimesUtc(DateTime? creationTimeUtc, DateTime? lastAccessTimeUtc, DateTime? lastWriteTimeUtc)` which should be public. 16195 area-System.Runtime ValueTuple in desktop 4.6 app clashes with that of mscorlib 4.7 Repro: 1.

Short version of this problem: We have a timing issue in the p/invoke logic for WSARecv that can cause received data to be corrupted when you use SocketAsyncEventArgs and ReceiveAsync in a particular way. You need to: (a) Use multiple buffers via SocketAsyncEventArgs.BufferList (not SetBuffer) (b) In the completion callback for the ReceiveAsync, you need to change the BufferList and then call ReceiveAsync.

You can check `default(T) != null` and be 100% confident something is a struct if that condition is true, but if `default(T) == null` then it could be a class or a nullable. The only way to tell right now is via reflection, using something like `typeof(T).IsGenericType && typeof(T).GetGenericTypeDefinition() == typeof(Nullable<>)`. I did want to use such an API several times in the past, although I can't recall where. One scenario I can think of though is if you want to treat `T` as an object if `T` is a class, but avoid boxing for structs. Does this sound like a good idea? Moved from https://github.com/dotnet/corefx/issues/16209 /cc @benaadams @jkotas 16221 area-System.Threading "Add primitive/exchange type for a ""single fire"" event" We have several places where we need to represent an event that fires once and classic .NET events are a poor way to represent it because of the following reasons: - Events don't describe if they fire once or multiple times, you have to trust the API (like a connection closed event handler should only fire once) - There's no way to poll events. In some cases it my be reasonable to check if the event has fired without subscribing. This is clunky with events. - There's no way to pass it around to others that may want to subscribe. If you want to do this with events, you need to pass around the object that the event hangs off of so that new handlers can be added. That might be a problem if you just want to scope things to the event itself. For these reasons ASP.NET tends to use CancellationTokens to represent such events e.g. https://github.com/aspnet/Hosting/blob/c4ea355ddfbe37234393af798b69943ee0ba649a/src/Microsoft.AspNetCore.Hosting.Abstractions/IApplicationLifetime.cs#L17-L30. Cancellation tokens aren't great in general because they aren't an abstraction. As an event implementor, you might want to bind directly to an underlying system without going through the cancellation token API. As as example of this, our caching API has an abstraction called an `IChangeToken` which is basically something with all of the above characteristics https://github.com/aspnet/Common/blob/8688579b29eb37f5b3a5b5dfdb83f0fad1063af5/src/Microsoft.Extensions.Primitives/IChangeToken.cs. Here's an example of a change token implementation that triggers based on polling the disk (you could imagine a more efficient API). https://github.com/aspnet/FileSystem/blob/c2d31b2df95aab3c758fa82b22f1ba9782b4bfd8/src/Microsoft.Extensions.FileProviders.Physical/PollingFileChangeToken.cs /cc @stephentoub 16222 area-System.Memory Faster Span Slim the span hot methods `.ctor`+`Slice` as they are very hot and always inlined Vectorized `IndexOf` for byte and `SequenceEqual` for byte and char /cc @jkotas 16223 area-Infrastructure All Tests failing > Failure to restore a package: Unable to resolve 'coveralls.io (>= 1.4.0)' for '.NETStandard,Version=v2.0'.

It's is difficult to avoid class-with-same-name-as-namespace problems here, but hopefully what I've ended-up with is acceptable. Multi-directory tests within corefx seem to be arranged with a variety of layouts/naming conventions, so I tried to pick something which was reasonably consistent with that. There are no changes beyond the moves and the namespace changes, and the deletion of the example 'smoke test' which seems to be redundant now. 16229 area-Meta Cleanup types duplicated between CoreCLR and CoreFX The following types are implemented in BOTH CoreFX and CoreCLR (corelib). Generally a type doesn't need to be duplicated. If it has to be in corelib (because other types in corelib need it) it can be removed from CoreFX. (Exception, where only a small piece of the type is actually needed in corelib, it can be convenient to leave the full implemention in Corefx - it shares for free and easier to work on there. However the corelib copy should be renamed to avoid confusion (eg Internal prefix)) Need to go through these and de-dupe/rename as appropriate. Note implementations will have diverged so the copies need to be reconciled first. Eg., BitConverter implementations are quite similar, but reformatted and not quite identical implementation. ``` public static class BitConverter public static class Environment public interface IServiceProvider public abstract class CollectionBase : ICollection, IEnumerable, IList public static class StructuralComparisons public abstract class KeyedCollection : Collection public class ReadOnlyDictionary : ICollection, ICollection>, IDictionary, IDictionary, IEnumerable, IEnumerable>, IReadOnlyCollection>, IReadOnlyDictionary public enum SearchOption public static class RuntimeReflectionExtensions public static class CompilerMarshalOverride public sealed class SpecialNameAttribute : Attribute public static class FormatterServices public abstract class SecurityState public class CountdownEvent : IDisposable public sealed class ThreadAbortException : SystemException ``` 16231 area-System.Linq Prohibit open generics in Expression.Property and Expression.Field Contributes to #8081.

Somewhat related to https://github.com/dotnet/corefx/issues/16126. I looked into some of the recent packages and they are unsigned. I believe this is because the signing is happening on the TargetPath but we're packaging the binplaced output of the project. It seems that when the signing task copies the signed file back from the signing server it breaks the hardlink. This will be coicidentally fixed when I do the work described here: https://github.com/dotnet/corefx/issues/14594, but that's only a fix for packaging. The tests also run on a binplaced copy of the project output, so that means that the tests are also getting unsigned binaries. /cc @weshaggard @mellinoe 16240 area-System.IO CI Failure in System.IO.Tests.FileStream_LockUnlock.OverlappingRegionsFromOtherProcess_ThrowsException https://ci.dot.net/job/dotnet_corefx/job/master/job/ubuntu14.04_release_prtest/3515/testReport/junit/System.IO.Tests/FileStream_LockUnlock/OverlappingRegionsFromOtherProcess_ThrowsException_fileLength__10__firstPosition__3__firstLength__5__secondPosition__2__secondLength__4_/ ``` Stacktrace MESSAGE: Assert.Equal() Failure\nExpected: 42\nActual: 145 +++++++++++++++++++ STACK TRACE: at System.Diagnostics.RemoteExecutorTestBase.RemoteInvokeHandle.Dispose() in /mnt/j/workspace/dotnet_corefx/master/ubuntu14.04_release_prtest/src/Common/tests/System/Diagnostics/RemoteExecutorTestBase.cs:line 159 at System.IO.Tests.FileStream_LockUnlock.OverlappingRegionsFromOtherProcess_ThrowsException(Int64 fileLength, Int64 firstPosition, Int64 firstLength, Int64 secondPosition, Int64 secondLength) in /mnt/j/workspace/dotnet_corefx/master/ubuntu14.04_release_prtest/src/System.IO.FileSystem/tests/FileStream/LockUnlock.cs:line 169 ``` 16241 area-System.Net Fix Http test that randomly fails under Windows Addresses #13938 where the test is failing randomly under Windows due to random exception when an http request is being canceled.

w/o RID The workaround being used by our build system to only build these packages on Windows was leaking into the packaging. To fix that I overrode the packaging RID for Unsafe, since it was the only thing that actually needed the filtering. Then to fix Memory I added a reference assembly for unsafe and built against that instead. Eventually we'll be able to remove the filtering from unsafe but having a reference assembly for this is general goodness. I also tried to tackle cross-compiling Unsafe for netstandard.dll and hit what appears to be a bug in `ilasm`. It didn't like me claiming that System.Object was in netstandard, and instead tried to insist it was in mscorlib and added a reference to that to the output assembly. I could change System.Object to some other type (eg: System.Attribute) and it was fine. @jkotas I think this is one of those hard-coding-the core assembly bugs. We should see if it's fixed by using a newer ilasm (@mellinoe is working on that), if not we should hunt it down and fix it in coreclr. /cc @mellinoe @ahsonkhan @weshaggard 16246 area-Infrastructure Enable Dumpling for all Unix CI tests "* Pass a simple flag ""IsCIBuild"" in netci.groovy into each invocation of `build-tests.cmd/sh` * In dir.props, define a common set of properties that are contingent on ""IsCIBuild"", so that those properties don't need to be duplicated everywhere in netci.groovy. * Set EnableDumpling=true for Unix builds (Windows support forthcoming).

The expectation should be the same as in Linux - a task status of Canceled, or perhaps RanToCompletion if the task already completed For example, the last Assert below may fail randomly (especially consistent in Windows 2008r2) because task.Status will be Faulted. ```` var cts = new CancellationTokenSource(); using (var client = new HttpClient()) using (HttpResponseMessage response = await client.GetAsync(Configuration.Http.RemoteEchoServer, HttpCompletionOption.ResponseHeadersRead)) using (Stream stream = await response.Content.ReadAsStreamAsync()) { var buffer = new byte[2048]; Task task = stream.ReadAsync(buffer, 0, buffer.Length, cts.Token); cts.Cancel(); Assert.True(((IAsyncResult)task).AsyncWaitHandle.WaitOne(new TimeSpan(0, 5, 0))); Assert.True(task.Status == TaskStatus.RanToCompletion || task.Status == TaskStatus.Canceled); } ```` We need to decide if we should harden the code to check the cancellationtoken and\or invalid handle in the various windows-only Http code such as in WinHttpResonseStream and avoid a random ObjectDisposedException, task canceled exception or other http exception depending on timing. Avoiding a race condition in this check may or may not be feasible (as handle or cancellationtoken may change to invalid\cancel in other thread) so consider try\catch of certain exceptions instead and then verify handle and\or cancellationtoken. cc @stephentoub @CIPop @davidsh 16251 area-Infrastructure Crossbuild was reporting incorrectly to the infrastructure. - Add arm as a Platform param for reporting for crossbuild skip ci please 16253 area-System.Net Change host to idnhost on curlhandler. cc @stephentoub @davidsh @CIPop @geoffkizer @karelz Verified with the URL provided in the issue, and the request is successfully parsed by curl.

This delays the closing/disposing of a `SerialPort` which has incomplete `BeginRead/BeginWrite` operations on it. This often manifests itself as an inability to open a port immediately after closing it. Within Core this has given rise to issue #16055 - that issue contains some content from an MS-internal bug database which is useful reference. Ideally we would fix this at some point, as time-related close-then-reopen failures cause pain in real-life and don't do much good to the reputation of `SerialPort`.

public static SomethingExpensive Expensive => LazyInitializer.EnsureInitialized(ref s_expensive, () => SomethingExpensive()); ``` It has several overloads, that can be split into two groups: - Optimistic concurrency - Pessimistic concurrency ```C# public static class LazyInitializer { // Optimistic public static T EnsureInitialized(ref T target) where T : class; public static T EnsureInitialized(ref T target, System.Func valueFactory) where T : class; // Pessimistic public static T EnsureInitialized(ref T target, ref bool initialized, ref object syncLock); public static T EnsureInitialized(ref T target, ref bool initialized, ref object syncLock, System.Func valueFactory); } ``` The optimistic concurrency overloads don't use locks, only interlockeds. This means you don't need a separate lock object and the first access can be faster, but in a contended initialization situation, you may end up with multiple objects getting created (only one of them will be published/used). The pessimistic concurrency overloads do use locks, with a double-checked locking pattern. This means you can be guaranteed to only have one object instantiated in the case of contention, but you also need a separate lock object. For the pessimistic overloads, all of them work with any T, regardless of whether it's a value type or a reference type, and thus in addition to accepting an object, they also require passing a reference to a bool, which indicates whether the field has been initialized or not. That's great for value types, but often for reference types that additional Boolean field is unnecessary, as whether it's been initialized is covered by whether the field is null or not. ### Proposal: We should add the following overload: ```C# public static T EnsureInitialized(ref T target, ref object syncLock, System.Func valueFactory) where T : class; ``` (the same as one of the existing pessimistic overloads, but without the ref bool, and with a class constraint on T) This will allow EnsureInitialized to be used in situations where you're using a ref type, want double-checked locking, and don't want/need to have an extra bool field to track initialization, since that can be done via null/non-null of the target field itself. 16275 area-Meta [Feedback] Can not update to .NETCore 1.1.0 after upgrading to Microsoft.NETCore.UniversalWindowsPlatform v5.3.0 Internal bug 385268 & vsfeedback issue 806440 Create UWP project with VS2015 and upgrade UWP package to v5.2.2 Open project in VS2017 RC3 - RC4.

The fix is to add 'socket.NoDelay = true' before the call to ReadWriteAcceptedAsync and then an 'await Task.Delay(100) afterwards.

In fact, we tend to use it quite often (despite its limitations to emit only to static methods) in Bing, so I'd be interested in getting it back in .NET Core. All the code still seems to be there; just the entry-point was removed rather than conditionally excluded. The entry-point came back conditionally excluded when that issue was closed. I also agree it can be useful, while I've only used it a handful of times myself, it was really useful those few times. That Xamarin is now using this feature adds another advantage, in that we can't test it, and hence catch regressions that could break Xamarin, without it. Mostly though I just think it can be useful, and is worth having. `CompileToMethod()` has dependencies on most of what is covered by `FEATURE_COMPILE` so replacing `FEATURE_COMPILE_TO_METHODBUILDER` with `FEATURE_COMPILE` would bring it back in those builds that can feasibly use it (i.e. have support for Emit). The mechanism for testing across both interpreter and compiler could be extended to test across all three possibities of interpreter, compiler and `CompileToMethod()` with dynamic methods, but other cases should probably be separate choices. `CompileToMethod()` would require a separate set of tests. - [ ] Approve change. - [ ] Replace `FEATURE_COMPILE_TO_METHODBUILDER` with `FEATURE_COMPILE` - [ ] Update `TryEmitConstants` to handle `TypeBuilder` constants when not emitting to `DynamicMethod` (may do this separately anyway if @marek-safar needs it). - [ ] Update tests to include `CompileToMethod()` with `DynamicMethod`s - [ ] Add tests for compiling to static methods. 16288 area-System.Linq Test SwitchExpression in S.L.Expressions that switch to gotos Special-cased by compiler and not yet covered in testing.

But, moreover why is this checked anyways? For example, what if I'd like to include invalid header values in my acceptance tests to ensure the server is responding appropriately? How should I set this up in my tests if I can't do this? This creates a limitation around which scenarios can be reproduced in code. ``` request.Content.Headers.ContentType = new MediaTypeHeaderValue(""text/html; charset=ISO-8859-4""); ``` From what I can tell this method disallows ANY [media type parameters](https://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.7) which doesn't make much sense to me." 16292 area-System.Net fix(MediaTypeHeaderValue): should allow media type parameters Closes #16290 16293 area-System.Data SqlClient Exception tests should be moved to inner loop SqlClient exceptions test should be moved to Inner Loop, at least the ones that can fail fast and provide results quickly. 16295 area-System.Collections Delay Random allocation in ConcurrentStack ConcurrentStack currently uses a randomized-backoff scheme, where under contention it spins for increasingly longer periods of time, with a duration influenced by some randomness. If the initial attempt at popping an item fails due to contention, it allocates a Random, then tries again one or more times, and then uses the randomness to influence backoff for subsequent attempts. While it's not clear to me that this scheme is optimal, we can at least delay the allocation of the Random (and the underlying cost it entails, like an int[] in its ctor) until it's actually used. Since it's typically not used for a few attempts, this significantly decreases the number of instances that get created under heavy contention. cc: @kouvel, @alexperovich 16296 area-System.Security Support OpenSSL 1.1 [OpenSSL 1.1.0 was released](https://www.openssl.org/news/openssl-1.1.0-notes.html) in August 2016. Various distributions are starting to switch to it now: - [Arch](https://lists.archlinux.org/pipermail/arch-dev-public/2017-January/028673.html) - [Debian](https://wiki.debian.org/OpenSSL-1.1) - [Fedora](https://fedoraproject.org/wiki/Changes/OpenSSL110) OpenSSL 1.1.0 breaks both API and ABI. There's a large list of APIs that were removed. Most structs were made opaque. As a result .NET Core in general and CoreFx in particular fails to build or run there. There's an incomplete list of API changes and porting tips available at [the OpenSSL Wiki](https://wiki.openssl.org/index.php/1.1_API_Changes). 16297 area-System.Data Enable exception tests in inner loop I have removed the [OuterLoop] attribute from exception tests.

It's useful. 16305 area-Meta Remove unnecessary use of `GetTypeInfo()` in Linq/Expressions/Dynamic, etc.. Possibly a dupe. `GetTypeInfo` patterns like `someType.GetTypeInfo().IsValueType` were added to workaround initially reduced API surface of `System.Type`. I think we have most of those APIs back on `System.Type` and it is likely more efficient to call them directly. (need to confirm, but it is unlikely that calling via `Sysyem.Type` cost more since as last resort it could just use GetTypeInfo internally, although it is doubtful). 16306 area-System.Net pinning bug in Socket.SendTo on Windows From looking at the code, it appears we are not properly locking the socketAddress buffer to Socket.SendToAsync. https://github.com/dotnet/corefx/blob/bfac45af5dddcbd70b6935fcf92b4b8755f3cd1c/src/System.Net.Sockets/src/System/Net/Sockets/SocketPal.Windows.cs#L947 The linked code does the following: (1) Call SetUnmanagedStructures with pinSocketAddress == false; so socketAddress won’t be pinned (2) Retrieve unmanaged pointer to the socketAddress buffer via asyncResult.GetSocketAddressPtr: (3) Pass this pointer to WSASendTo We need to either lock this buffer, or copy it locally to the stack before we use it. 16308 area-System.Net Unix SocketAsyncEventArgs implementation should clone user-provided buffer list When the user sets the BufferList property, we store it and then directly use this whenever we perform a socket operation, e.g.: https://github.com/dotnet/corefx/blob/684af05e70b345eecd503e23d0d6d4efd67f9130/src/System.Net.Sockets/src/System/Net/Sockets/SocketAsyncEventArgs.Unix.cs#L251 This means that the user can mutate the list after setting it (or even concurrently), and we will see a different buffer list than they originally set. This is not the intended behavior. On Windows, we avoid this by preconstructing the WSABuffer structures when the BufferList is set, so we don't have this issue. We should clone the list when it's set to avoid this problem. 16310 area-System.Net GetResponse_UseDefaultCredentials_ExpectSuccess test failed in CI https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_centos7.1_release/102/ System.Net.Tests.HttpWebRequestHeaderTest.GetResponse_UseDefaultCredentials_ExpectSuccess(remoteServer: https://corefx-net.cloudapp.net/Echo.ashx) [FAIL] System.Net.WebException : An error occurred while sending the request.

There are various implementations of this in the legacy code - some have no timeout (and hence hang the test completely if there's a problem), some have a timeout but don't care if the timeout exceeded or not (which in some cases conceals defects in the test code), and some have a timeout followed by a separate check on buffer content.

APIs like Marshal.UnsafeAddrOfPinnedArrayElement, etc., it's often desirable to be able to assert that the object in question is in fact pinned. I'd like to see an API that would allow that to be done: ```C# public struct GCHandle { public static bool IsPinned(object value); ... } ``` Similar to how Monitor.IsEntered is mainly intended to be used in Debug.Asserts, this could then be used in Debug.Asserts as well, e.g. ```C# Debug.Assert(GCHandle.IsPinned(arr)); IntPtr arrPtr = Marshal.UnsafeAddrOfPinnedArrayElement(arr, 0); ... // pass arrPtr to P/Invoke ``` My understanding is the runtime doesn't currently track enough information to make such a look-up fast, but that's ok for the debug-only purposes for which it is intended. The runtime could do whatever parts of a GC scan are necessary to determine whether the object is pinned, worst case doing a full GC. 16348 area-System.Xml AV in System.Xml.XmlDocument.Tests in CI https://ci.dot.net/job/dotnet_corefx/job/master/job/code_coverage_windows/107/consoleText ``` Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.AccessViolationException: Attempted to read or write protected memory.

Console.KeyAvailable echoes typed key on Linux and macOS I've been using `Console.KeyAvailable` to implement an async `ReadKey` method that waits until a key is available before calling `Console.ReadKey(true)`. This has been working well on Windows but it breaks down on *NIX because the `Console.KeyAvailable` property causes the typed key to be echoed. This happens before I have a chance to call `ReadKey` specifying that I don't want it to echo the typed key. Is this a bug? If not, is there some way I can tell the console implementation to not echo keys when `KeyAvailable` is used? /cc @stephentoub 16353 area-Infrastructure Solutions missing cross-platform configurations We used to have the option in VS of selecting which configuration of the project you want to work with, e.g. a pull down to select Windows vs Linux vs macOS for Debug vs Release.

This has caused us to significantly hamper the Socket.{Begin}Connect{Async} instance methods on Socket, in two ways: 1) If you call any instance connect overload and it fails, whereas on Windows you can try to connect again, on Unix we throw a PlatformNotSupportedException. 2) If you call any instance connect method that could potentially try to connect to multiple addresses (e.g. a string host, an IPAddress[], or a DnsEndPoint), whereas on Windows that allowed, on Unix we throw a PlatformNotSupportedException (because after trying the first address we will then be trying to connect again on a socket that failed to connect). There are multiple options for dealing with this, all with their own pros and cons: A) Use a ""shadow"" socket to first try to make the connection, and if it succeeds, assume that another connection will succeed and try to make it on the ""real"" socket. We actually originally went down this path prior to .NET Core 1.0 and it had significant problems, both with performance (multiple connections any time a single one was needed) and with server expectations (getting two connections when only one was expected). B) Prohibit usage of any {Begin}Connect{Async} APIs that could potentially deal with multiple addresses. This is what we've shipped in .NET Core 1.x. C) In such APIs, check whether the number of addresses is exactly 1, allowing it if there is, throwing otherwise. This has several issues, including problems with dual mode (e.g. localhost will often resolve to both ::1 and 127.0.0.1), non-determinism based on how many addresses a server resolves to, etc. D) Regardless of the number of addresses, pretend there was only one. This has similar issues to (C). E) Use a ""shadow"" socket to make each connection, and then on successful connection substitute it in for the original underneath the Socket. This enables trying to connect to multiple addresses, but it means that any configuration performed on the initial socket won't be applied to the subsequent sockets. F) Same as (E), but keeping track of some dialable set of options that can be propagated from socket to socket. This commit implements (F). (F) still isn't perfect, but it allows the common path (minimal configuration) to work while still supporting multiple endpoints and being deterministic: - SafeCloseSocket on Unix now tracks whether the Socket.Handle property was accessed and whether any non-tracked configuration was set. If any of that is done, then as with today. We were already tracking (in order to provide an error message) whether a connect attempt failed; that was previously tracked on the SocketAsyncContext, now it's tracked on the SafeCloseSocket handle. - Whenever an attempt is made to {Begin}Connect{Async} with multiple possible endpoints, we check whether the handle was exposed or untracked configuration was used. If it was, we fail as we do today. If it wasn't, we allow it. - When making a connection (either via a user's call, or as part of a multi-endpoint connect operation), if there was a previously failed connection attempt, we replace the handle with a new one, transferring over the tracked state from the old handle to the new one. - Removed a bunch of stale code leftover from when approach (A) above was implemented; apparently when we switched to (B) this code was never removed - Removed now defunct [PlatformSpecific] attribution, and added some more tests With (F), we also no longer need the workaround we had in TcpClient, so I recombined it back down to a single implementation built on top of Socket. This means, for example, that whereas previously on Unix you couldn't use TcpClient's instance Connect methods with a DNS endpoint after accessing its Client Socket, now you can. And we don't have to do any of the shadow value tracking we were previously doing. In addition, I took care of some other minor cleanup I spotted along the way: - One or two cases where API usage was ifdef'd out; now that these APIs are back for 2.0, we can use them again, e.g. IPAddress.Address - Fixed a few places where exception stacks were being lost due to exceptions getting rethrown; changed these to use ExceptionDispatchInfo to maintain the stacks (this helped me to debug a few things better, which is how I noticed in the first place) - Removed unnecessary pragma usage that was a holdover from older versions of the code - Adding code to a bunch of tests to Dispose of sockets - Adding a few more tests (there's still a lot of uncovered code in Sockets unfortunately; we really need to address that, separately) Fixes https://github.com/dotnet/corefx/issues/8768 cc: @NickCraver, @tmds, @glennc, @geoffkizer, @danroth27, @richlander, @pgavlin, @halter73" 16374 area-System.Collections [Proposal] Adding a version of List with smaller memory footprint and no random access **Related:** https://github.com/dotnet/corefx/issues/15573 **Background:** When `Add` is called on List and it cannot fit any more items in its internal buffer, it allocates a new array twice the size and copies over each of the existing items. This is an inefficient use of memory; instead, it could keep the old array around, allocate a new one the same size as the number of existing items, and continue reading items into that array with no copying. This is what [`LargeArrayBuilder`](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Collections/Generic/LargeArrayBuilder.cs) does, which is used by Linq's `ToArray` method today, and the number of allocations [has been shown to decrease by 33%](https://github.com/dotnet/corefx/pull/11208) as a result. Here is a visualization of how 200 items will be stored: ```cs Buffers = new T[][] { [0] = new T[8], // Stores items 0-7 [1] = new T[8], // Stores items 9-16 [2] = new T[16], // Stores items 17-32 [3] = new T[32], // Stores items 33-64 [4] = new T[64], // Stores items 65-128 [5] = new T[128] // Stores items 129-199, slots 200-255 are zero-inited } ``` When one buffer runs out of space we can simply add it to `Buffers` and continue reading in items to a new buffer, without copying anything or wasting memory. **Proposal:** The public version will be a class and implement `ICollection`. It will be named `ArrayBuilder`, since in the related issue we decided we're not going to expose the internal `ArrayBuilder`. It will expose a minimal API and explicitly implement a few `ICollection` members. ```cs namespace System.Collections.Extended { public class ArrayBuilder : ICollection, IReadOnlyCollection { public ArrayBuilder(); public ArrayBuilder(int capacity); public ArrayBuilder(IEnumerable items); public ArrayBuilder(int capacity, IEnumerable items); // ICollection members public int Count { get; } public void Add(T item); public void Clear(); public bool Contains(T item); public void CopyTo(T[] array, int arrayIndex); public Enumerator GetEnumerator(); public T[] ToArray(); // Explicitly implemented ICollection members bool ICollection.IsReadOnly { get; } bool ICollection.Remove(T item); IEnumerator IEnumerable.GetEnumerator(); IEnumerator IEnumerable.GetEnumerator(); public struct Enumerator : IEnumerator, IEnumerator { public T Current { get; } public void Dispose(); public bool MoveNext(); void IEnumerator.Reset(); } } } ``` The type will not implement `IList`. Random access will be O(log n) because we'd have to walk over each of the buffers and subtract its size from the index, and each buffer will be double the size as the previous. **Addtional notes:** - Roslyn already has an `ArrayBuilder` type used in a lot of places, so I'm open to changing the name if the name clashes with that project will be a concern. - The namespace will be `System.Collections.Extended` so `System.Collections.Generic` stays lean.

"## Proposal: TCP Fast Open TCP Fast Open is an extension for TCP to speed up the handshaking process in successive TCP connections. This feature has been available for OSX and Linux for years and was implemented on Windows by Anniversary Update. Users could check by `netsh` ``` >netsh int tcp show global Querying active state... TCP Global Parameters ---------------------------------------------- ... TCP Fast Open : enabled ``` but dotnet has not implemented this for System.Net yet. ### Rational and Usage This new API is important and powerful because when it is used with TLS False Start, we are down to 1-RTT from original 3-RTT for a successive TCP+TLS (HTTPS) connection, and furthermore, 0-RTT could be achieved by combining TFO and TLS 1.3. And it's easy to use: programmers only need to add a few lines to set an socket option and provide a buffer filled with data to send. Here's the usage: ``` C# var s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); var e = new SocketAsyncEventArgs(); s.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.FastOpen, true); e.SetBuffer(buffer, offset, length); s.ConnectAsync(e); ``` Note that `buffer[offset]` ~ `buffer[offset+length-1]` might be (partially) sent together with SYN. It's up to the OS how to send. A typical usage is the TLS handshake. In successive connections, the client could send a SYN with TLS Client Hello. Please check the ""Original Proposal"" for details. ### Proposed API ``` C# namespace System.Net.Sockets { // Defines socket option names for the class. public enum SocketOptionName { // ... #region SocketOptionLevel.Tcp // ... FastOpen = 15 #endregion } } ``` This enum value is 15 for Windows according to `ws2ipdef.h`. ### Problems & Extra works - Implementation In fact, adding just one line like the code above in [SocketOptionName.cs](https://github.com/dotnet/corefx/blob/bffef76f6af208e2042a2f27bc081ee908bb390b/src/System.Net.Sockets/src/System/Net/Sockets/SocketOptionName.cs) would work for Windows. However, it might not work for Unix. Since dotnet simply pass the socket option to native API on Windows while the Unix Pal would check the value. For more information about the difference please check the relevant issue #14237 . To make this work for Unix we may need to modify [this part](https://github.com/dotnet/corefx/blob/master/src/Native/Unix/System.Native/pal_networking.cpp#L2103-L2113) - Compatibility According to [MSDN](https://msdn.microsoft.com/en-us/library/windows/desktop/ms738596(v=vs.85).aspx), this option is available since Windows 10, 1607. Maybe we should generate a warning if this option is set on the older Windows platform - Other System.Net API For API using sockets in its code such as WebClient or HttpClient, it could take advantage of this feature, especially for ""https://"" scheme. ### Original Proposal #### TCP Fast Open on Windows Windows has introduced TCP Fast Open in the Anniversary Update serveral months ago. ([Announcing: New Transport Advancements in the Anniversary Update for Windows 10 and Windows Server 2016](https://blogs.technet.microsoft.com/networking/2016/07/18/announcing-new-transport-advancements-in-the-anniversary-update-for-windows-10-and-windows-server-2016/)) > TFO is one full Round Trip Time (RTT) faster than the standard TCP setup which requires a three way-handshake. This leads to latency savings and is very relevant to short web transfers over the Internet where the average latency is on the order of 40 msec. #### Native API for TCP Fast Open This feature could be turned on using native Windows Socket 2 API: [IPPROTO_TCP Socket Options](https://msdn.microsoft.com/en-us/library/windows/desktop/ms738596(v=vs.85).aspx). But it has not been implemented in dotnet ([SocketOptionName.cs](https://github.com/dotnet/corefx/blob/bffef76f6af208e2042a2f27bc081ee908bb390b/src/System.Net.Sockets/src/System/Net/Sockets/SocketOptionName.cs)). #### dotnet API relating to TCP Fast Open According to the Native API Documentation, in addition to passing a new enum value to the method `setSocketOption` which then calls the native `setsockopt`, we need to set up the buffer including the data to send during the initial connection: >Note that to make use of fast opens, you should use ConnectEx to make the initial connection, and specify data in that function's lpSendBuffer parameter to be transferred during the handshake process. Some of the data in lpSendBuffer will be transferred under the Fast Open protocol. The native method `ConnectEx` is called by [`DoOperationConnect`](https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/src/System/Net/Sockets/SocketAsyncEventArgs.Windows.cs#L235) which is called by [`socket.ConnectAsync`](https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/src/System/Net/Sockets/SocketAsyncEventArgs.Windows.cs#L235) on Windows. And the buffer could be set as a property of SocketAsyncEventArgs. ```C# //TFO is defined as 15 in ws2ipdef.h socket.SetSocketOption(SocketOptionLevel.Tcp, (SocketOptionName)15, true); e.SetBuffer(buffer, start, length); //e is a SocketAsyncEventArgs socket.ConnectAsync(e); ``` #### dotnet implementation The most straightforward way to implement this feature is to add a new value to the SocketOptionName enum. But it enables this feature only on Windows. In this issue https://github.com/dotnet/corefx/issues/14237, it seems that members are interested in introducing a new cross-platform API for TCP options. >It would be nice if the Public API contained all of the possible socket options across Windows, Linux, and Darwin.

An additional use case for this is as the basis for a basic text templating system where the values can be dynamically retrieved using the `Func` overload. ## Proposed API ```diff namespace System { public class String { + public static string Format(string format, Func valueProvider); + public static string Format(string format, IDictionary valueProvider); } } ``` ## Details * The implementation would simply be a wrapper around the original `string.Format` but replace named arguments with indices. * An `Ordinal` string comparison will be used to determine reuse of named arguments. * The `IDictionary` overload will use its `TryGetValue` method for retrieving the value. * A `FormatException` is thrown when a value for a named argument cannot be found. ## Updates * Changed `valueProvider` from a `Func` to a `Func` to support specifying if the named argument was found. * Changed example to explicitly show retrieving the `logFormat` value from configuration. * Added the templating system use case." 16418 area-System.Runtime Add RIDless build configuration for S.R.IS.RuntimeInformation This AnyOS netstandard1.1 configuration is for PCL support so we ensure we have an asset that isn't in a runtime folder in the package which PCL's and packages.config don't support.

On a machine building multiple different verticals without cleaning, this could cause clashes / mismatches. If you review a build log where this happens, you see stuff like: ` E:\A\_work\89\s\corefx\packages\runtime.win7-x86.Microsoft.NETCore.Runtime.CoreCLR\2.0.0-beta-25021-03\runtimes\win7-x86\native\sos.dll (runtime.win7-x86.Microsoft.NETCore.Runtime.CoreCLR.2.0.0-beta-25021-03) -> E:\A\_work\89\s\corefx\bin\Windows_NT.AnyCPU.Debug\runtime\netcoreapp\sos.dll` but, we use the same output path for x64 as well. It would be useful for this to take into consideration the Arch of what's being copied when generating layouts like this. 16428 area-System.Numerics Add support for Acosh, Asin, Atanh, and Cbrt to System.Math and System.MathF ### Rationale The .NET framework does not currently provide support for several of the mathematical functions that are available to the C/C++ Standard Library. Support should be provided for these mathematical functions in order to better interop with high-performance, scientific, and multimedia-based applications where these functions may be in demand. Several of these functions, such as `ExpM1`, may be more accurate or may return values for inputs outside the range of the corresponding code written manually (`EXP(x) - 1`). ### Approved API ```C# public static partial class Math { // Hyperbolic Functions public static double Acosh(double); // Compute area hyperbolic cosine public static double Asinh(double); // Compute area hyperbolic sine public static double Atanh(double); // Compute area hyperbolic tangent // Power Functions public static double Cbrt(double); // Compute cubic root } public static partial class MathF { // Hyperbolic Functions public static float Acosh(float); // Compute area hyperbolic cosine public static float Asinh(float); // Compute area hyperbolic sine public static float Atanh(float); // Compute area hyperbolic tangent // Power Functions public static float Cbrt(float); // Compute cubic root } ``` ### Unapproved APIs The following APIs were also reviewed but rejected at this time. The discussion ended up that these would likely be better suited in a `MathExtensions` or similar class provided through a separate library (and likely implemented using the hardware intrinsics functionality rather than as FCALLs in the runtime). ``` C# public static partial class Math { // Exponential Functions public static double Exp2(double); // Compute binary exponential public static double ExpM1(double); // Compute exponential minus one // Logarithmic Functions public static double Log1P(double); // Compute logarithm plus one public static double Log2(double); // Compute binary logarithm // Power Functions public static double Hypot(double, double); // Compute hypotenuse } public static partial class MathF { // Exponential Functions public static float Exp2(float); // Compute binary exponential public static float ExpM1(float); // Compute exponential minus one // Logarithmic Functions public static float Log1P(float); // Compute logarithm plus one public static float Log2(float); // Compute binary logarithm // Power Functions public static float Hypot(float, float); // Compute hypotenuse } ``` ### Additional Details This will require several changes in the CoreCLR as well to support the new APIs via FCALLs and Intrinsics. 16430 area-System.Data Failure in System.Data.SqlClient.Tests.DiagnosticTest.ExecuteNonQueryErrorTest ``` Stacktrace MESSAGE: Timed out after 60000ms waiting for remote process 7172\r\nExpected: True\r\nActual: False +++++++++++++++++++ STACK TRACE: at System.Diagnostics.RemoteExecutorTestBase.RemoteInvokeHandle.Dispose() in D:\j\workspace\outerloop_win---097a300f\src\Common\tests\System\Diagnostics\RemoteExecutorTestBase.cs:line 176 at System.Data.SqlClient.Tests.DiagnosticTest.ExecuteNonQueryErrorTest() in D:\j\workspace\outerloop_win---097a300f\src\System.Data.SqlClient\tests\FunctionalTests\DiagnosticTest.cs:line 95 ``` 16431 area-Infrastructure Binplace package file list /cc @weshaggard @chcosta @joperezr This switches binplacing for packaging to use file lists rather than copies. 16432 area-System.Net Cannot find System.Net.Dns in System.Net.NameResolution "I've added the following to my project.json: > ""System.Net.NameResolution"": ""4.3.0.0"", And yet I get this error on compile. > The name 'Dns' does not exist in the current context What am I doing wrong?

X509Certificates: * X509Certificate moves to using SecCertificateRef from OpenSSL's X509. * X509 metadata comes from a managed reader after being loaded by Security.framework, due to the significant amount of data that has no public export in Apple's libraries. * Significant code was factored out to be shared by OpenSSL and Apple implementations for X500DistinguishedName and X509Certficate2Collection.Find. * Loading a PFX (or, rather, the private keys from a PFX) via Apple's platform requires importing into a Keychain, and a Keychain requires a file on disk. A temporary keychain is created during cert loading and erased when safe. Like the perphemeral key load on Windows this can leak files due to abnormal program termination. * The X.509 My store for CurrentUser and LocalMachine are the default (user) and System keychains. * The X.509 Root store is an interpretation of the Apple SecTrustSettings data. * The X.509 Disallowed store hasn't been implemented yet, but should be a very small change. * Other X.509 stores cannot be created due to keychain complexity. HttpClient: * Initialization no longer wakes up OpenSSL SslStream: * New implementation based on Apple SecureTransport. * Currently has support for SNI (for AuthenticateAsClient) 16447 area-Infrastructure [release/1.1.0] Inbox value tuple Require buildtools update to build w/o validation errors. https://github.com/dotnet/buildtools/pull/1348 Fixes: #14235 /cc @jcouv @marek-safar @weshaggard 16448 area-System.Diagnostics [API Proposal] Debug.Assert overloads taking bool? "## Motivation For me, it's very frequent to assert something is non-null in a `Debug.Assert`. It is also frequent for me to verify some properties about that thing after asserting it is non-null. For example, if one wants to do a typical validation of array/index/count parameters, you would do ```cs Foo(T[] array, int index, int count) { Debug.Assert(array != null); Debug.Assert(index >= 0 && count >= 0); Debug.Assert(array.Length - index >= count); } ``` Here, we are first asserting the array is non-null and then asserting that there's enough room for `count` using the array's `Length` property. Usually, I like to take advantage of null-conditionals to condense these kinds of asserts: ```cs Foo(T[] array, int index, int count) { Debug.Assert(index >= 0 && count >= 0); Debug.Assert(array?.Length - index >= count); } ``` This works because `>=` in the second assert does a lifted comparison and returns false if the left side is `null`. Its result is a `bool`, which can be passed to `Debug.Assert` with no problems. In the following example, however, the assert fails to compile: ```cs void ReadingOperation(Stream stream) { Debug.Assert(stream?.CanRead); } ``` `stream?.CanRead` returns a `bool?`, which `Debug.Assert` does not know how to handle. This means the user has to have two asserts, one for asserting the stream is non-null and another for asserting it `CanRead`. ## Proposal Add overloads of `Debug.Assert` accepting a `bool?`. `null` values will be treated as `false`. ```cs namespace System.Diagnostics { public static class Debug { [Conditional(""DEBUG"")] public static void Assert(bool? condition); [Conditional(""DEBUG"")] public static void Assert(bool? condition, string message); [Conditional(""DEBUG"")] public static void Assert(bool? condition, string message, string detailMessage); [Conditional(""DEBUG"")] public static void Assert(bool? condition, string message, string detailMessageFormat, params object[] args); } } ``` I don't know what the last two overloads do since I've never used them before, but I added them for the sake of completion. If they have to be removed from the proposal that's fine with me. ## Implementation ```cs [Conditional(""DEBUG"")] public static void Assert(bool? condition) => Assert(condition.GetValueOrDefault()); ``` ## Additional notes xUnit already has `Assert.True` and `Assert.False` overloads that take nullable booleans.

This is documented, but is nonetheless a very bad behavior and should be changed to throw an ArgumentOutOfRangeException or return a NaN. Calculating trig functions of large arguments is hard for reasons well-known to numerical computing experts and much less well-known to most other programmers. The issue has a long history of sowing confusion. (See https://randomascii.wordpress.com/2014/10/09/intel-underestimates-error-bounds-by-1-3-quintillion/ and some references there.) One way of viewing the problem is that FP doubles have ~16 digits of accuracy, so once you get to values above ~6.0E16, there is a full 2\pi of ""uncertainty"" in the value, so we don't really know where we are within the period of the sine curve. The real solution to this problem would be to implement range reduction with a high-precision value of \pi, which would enable us to give 1-ulp accurate values of trig functions for all representable doubles. I will request that solution in another bug. This bug is about what we should do if we are not willing to implement the real solution. Page 3 of the paper https://www.csee.umbc.edu/~phatak/645/supl/Ng-ArgReduction.pdf has a table that compares the behavior of trig functions for large argument for ~30 different platforms. Some of them implement the real solution and so are able to give the correct answer. Others return what is essentially a random value between -1 and 1, or return 0 for sin and 1 for cos. Almost all of these platforms satisfy sin^2 + cos^2 = 1. Finally, some platforms return an error or a NaN to signal their inability to do the requested calculation. What none of them do is what .NET does: return the argument. Besides being unique, what .NET does is bad for a number of additional reasons: (i) One thing we know for certain about sin and cos values is that they must lie between -1 and 1; our behavior violates this rule. (ii) Another thing we know for certain about sin and cos values is that sin^2 + cos^2 = 1; our behavior violates this rule. (iii) Typically people don't call Math.Sin and Math.Cos as part of a program that just computes sines and cosines. Instead, the input argument is the result of a complex calculation and the output value feeds into other complex expressions that are supposed to produce the desired numerical result. It is very easy for a program to produce an input in the bad range in a way that is hard for the programmer to foresee. Without any clear error signal, it's also very easy for the program to go on to produce an ultimate numerical result that is not obviously the total bull**** that it in fact is. (iv) Of course, since we document this, we could argue that the programmer should check input validity before calling Math.Sin or Math.Cos. But if the programmer should always do this, why don't we do it for him? A single floating point comparison is not a high overhead. There are some applications where speed is of the utmost importance, more important even than validity. Gaming comes to mind. (Actually, pretty much only gaming comes to mind.) But we don't allow such considerations to outweigh the requirement for validity for other functions. No one would suggest that we replace Math.Sqrt with Carmack's famous fast inverse square root trick (https://en.wikipedia.org/wiki/Fast_inverse_square_root); we expect people who prefer a fast-and-usually-approximately-right answer to a slower-but-actually-correct answer to call a dedicated fast-but-approximate method.

Maybe it results in some insights for the current API. I will start with some basic questions and I will add further questions once I have a better understanding, if that's ok for you. ### Executing code on Start and Stop for *all* activities I think a tracer should be unaware of actual operation names like ""Http_In"" etc. Instead, the tracer should have a mode where it automatically picks up *all* activities. Of course, it will be useful to also allow users to filter these events (white-list or black-list). IIUC, the current hooks for this are the `[OperationName].Start` and `[OperationName].Stop` DiagnosticSource events as described in [Subscribe to DiagnosticSource](https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.DiagnosticSource/src/ActivityUserGuide.md#subscribe-to-diagnosticsource). Since `OperationName` is dynamic, I don't see an easy way to get *all* activities. Would I have to do something like the following to e.g. send all finished activities to a different system? ```csharp DiagnosticListener.AllListeners.Subscribe(delegate (DiagnosticListener listener) { listener.Subscribe(delegate (KeyValuePair value) { if ( // StopActivity writes an event with the suffix ""Stop"" value.Key.EndsWith(""Stop"", StringComparison.Ordinal) // However, there could also be other events that use this suffix // so we have to check if there's an activity && Activity.Current != null // There could also be ""*.Stop"" events while the activity is running && Activity.Current.Duration != TimeSpan.Zero) { // send stopped activity to external system } }); } ``` However, since there's no longer a filter outside of `Subscribe`, this would enable *all* diagnostic listener categories, wouldn't it? Also, the string comparison for the ""Stop""-suffix etc seems a bit odd. If the intend is to always have the category white-list, where/how should this be implemented in your opinion to keep the tracer (e.g. Application Insights) unaware of actual instrumentations? ### Using globally unique activity IDs Tracing systems need unique IDs to distinguish traces/activities. The Activity API defines a way to [set a custom root ID](https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.DiagnosticSource/src/ActivityUserGuide.md#root-id) through `SetParentId(string)`. If this API is not used, a simple int counter is used - which obviously isn't guaranteed to be unique across machines. IIUC, tracers are supposed to call `SetParentId` in `[OperationName].Start` events, right? Child activities however will then get add local increment IDs as suffixes to this parent ID without any way to change it. IIUC, this has several problems: * To call `SetParentId` on all activities, the tracer again has to listen to *all* `*.Start` events which might not be possible right now without enabling *all* diagnostic listener categories (see previous point) * Tracers might not be able to handle the format of child activities. They might e.g. always require random `long` values. * Child activities on different servers might get the same ID. Example: A server request generated a root ID of `123`. It then executes 2 child requests which are handled by different servers in a farm. If the local counter happens to be the same (e.g. on application startup), both would get the same child ID of ""123.1""." 16492 area-System.Memory System.Memory.Tests crashing on Windows outer loop runs "https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_windows_nt_debug/115/consoleText https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_windows_nt_release/111/consoleText https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_win10_debug/106/consoleText https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_win10_release/112/consoleText https://ci.dot.net/job/dotnet_corefx/job/master/job/code_coverage_windows/117/consoleText ``` Discovering: System.Memory.Tests Discovered: System.Memory.Tests Starting: System.Memory.Tests Finished running tests.

E.G.: ```csharp X509Certificate cert = new X509Certificate(""mycert.pxf""); byte[] b = cert. GetCertHash256() string s = cert. GetCertHashString256() ``` Alternatively, a variable hashing algorithm as function parameter would be desirable for future hashing methods. A use case is the ssl certificate validation on IoT devices to prevent man-in-the-middle attacks. Many IoTs connect to a web api via ssl and thus, should validate the server’s certificate. With limited compute power on the device the certificate’s thumbprint can be verified much cheaper than the whole chain of certificates. For example, the validation of a server certificate can be done with python on a Raspberry: ```python import ssl from cryptography import x509 from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import hashes thumbprint = 'e959fd5c80f76df7a593aae09686e604f74be8b0' pem = ssl.get_server_certificate( (host, port) ) certx509 = x509.load_pem_x509_certificate(str.encode(pem), default_backend()) tp = certx509.fingerprint(hashes.SHA256()) tpHex = ''.join('{:02x}'.format(x) for x in tp) if tpHex != thumbprint: print(‘Validation failed’) ```" 16498 area-System.Net IPAddressExtensions.Snapshot should not be public Looks like this became public at some point during porting.

There is a wrap around problem (if you allocate more than 4 billion IDs) The s_uniqPrefix is also not perfect as it uses the us granularity tick count to create a 'random' number. There certainly COULD be collisions if there were multiple processes on the same machine using activities and they both fetched their very first ID at the same time. There is also an issue when you create a ID from a ParentID coming from another system. Currently we simply append a process-wide sequence number to the ParentID, but if this happens on two different machines there can be a collision. Adding a machine-random number would avoid this. These are all very rare events, but if we can find cheap ways of making this better we should do so. 16502 area-System.Net Rewrite Socket Task-based send/receive async operations on SocketAsyncEventArgs They're currently on top of the APM methods. This commit changes the ReceiveAsync/Send{To}Async operations to instead sit on top of a cached set of SocketAsyncEventArgs instances. On a microbenchmark that connects two sockets and then does a million 1byte sends/receives from one to the other, top allocations before: ![image](https://cloud.githubusercontent.com/assets/2642209/23368963/b34f3226-fcdd-11e6-8c5d-05374dba4b3d.png) And top allocations after: ![image](https://cloud.githubusercontent.com/assets/2642209/23369063/1738fefc-fcde-11e6-97b4-7ac9c82c282d.png) In a small change that forces all receives to be asynchronous by doing them before the send, top allocations before: ![image](https://cloud.githubusercontent.com/assets/2642209/23370305/3fb64a02-fce2-11e6-8efe-514ee5687068.png) And top allocations after: ![image](https://cloud.githubusercontent.com/assets/2642209/23370313/47110472-fce2-11e6-88aa-d43259e8f83d.png) Throughput on the send/receive case also improved ~60%. Throughput on the receive/send case improved ~10%. The worst case for this change is when only one send/receive is done per socket, since then it doesn't benefit from the SocketAsyncEventArgs caching. It takes two send/receives per socket to break even on allocation, and after that it's a definitive win. With the task-based versions now generally much more efficient than the APM-based ones, I've switched NetworkStream.Read/WriteAsync to use them. cc: @geoffkizer, @cipop, @davidsh, @vancem 16503 area-System.Net Fix visibility of internal extensions type Fixes https://github.com/dotnet/corefx/issues/16498 cc: @geoffkizer, @cipop 16504 area-System.Memory Disable crashing System.Memory tests https://github.com/dotnet/corefx/issues/16492 cc: @jkotas, @ahsonkhan 16505 area-System.Diagnostics Add logging for System.Diagnostics.Tests.ProcessTests.TestExitTime For https://github.com/dotnet/corefx/issues/16489 cc: @danmosemsft 16506 area-Infrastructure Update buildtools and re-enable projects disabled due to Unix ilasm This re-enables the build for System.Runtime.CompilerServices.Unsafe on all platforms, and turns on the tests for System.Memory (they were disabled because Unsafe was disabled). @weshaggard @joperezr 16507 area-System.Threading Fix #16274 - LazyInitializer.EnsureInitialized overload for reference types.

You don't need to have the WebProxy class for that. The default behavior for HttpClientHandler just simply uses these settings to find the proxy. It has the proxy detection logic built-in. How is that behaviour impacted when hosting on IIS through the reverse proxy? ### First: The Error Here is the exception that pops up when I try to do a `HttpClient` `GetAsync()`, which Wireshark reveals is caused by the proxy cutting the request off (error 407). > System.Net.Http.HttpRequestException: Error while copying content to a stream. ---> System.IO.IOException: Unable to read data from the transport connection.

The web API is fairly simple, with some calls that GET another external resource. - Internet Explorer LAN Settings 'Automatically detect settings' ticked - Kestrel: Exception - IIS: Exception - 'Automatically detect settings' **un-ticked** - Kestrel: **No exception - it works** - IIS: Exception So it appears, at first glance, that `HttpClientHandler` is ignoring the Automatically detect settings bit, when run under IIS. What I'm also suspecting is that IIS AppPool account might affect what proxy setting the HttpClient sees, in some way. But I probably need someone from the dotnet team to actually comment.

Write blocked usually occurs during hardware flow control on the serial port where the remote side is causing the flow control. That is, while the remote side has indicated that sending is not possible so that Write() is blocked, Close() will block forever. A test case that shows this behaviour is: ```c# // NOTE: This test is expected to fail or block forever on Windows. [Test] [Timeout(4000)] public void SerialPortDisposedWhenBlocked() { byte[] buffer = new byte[1024]; using (SerialPort serialSource = new SerialPort(c_SourcePort, 115200, Parity.None, 8, StopBits.One)) using (SerialPort serialDest = new SerialPort(c_DestPort, 115200, Parity.None, 8, StopBits.One)) { serialSource.Open(); serialDest.Open(); serialDest.RtsEnable = false; new Thread( () => { Thread.Sleep(2000); Console.WriteLine(""Disposing serialSource""); // It appears that the MSDN .NET implementation blocks here, never // to return as we're blocked on another thread. serialSource.Dispose(); Console.WriteLine(""Disposed serialSource""); } ).Start(); int bufferCount = 1024 * 1024; while (bufferCount > 0) { serialSource.Write(buffer, 0, buffer.Length); bufferCount -= buffer.Length; Console.WriteLine(""{0}"", bufferCount); } } } ``` To test you will need real hardware that supports hardware flow control (e.g. a cable that also has RTS/CTS correctly wired), not just a simple three-wire cable. For example, this is reproducible on 2 USB FTDI chipsets with a NULL-Modem cable between that connects the RTS/CTS from each port to the other port. It works by telling the source port to send data, usually it will block within the first 2 seconds due to internal OS buffers. Then it becomes write blocked. The thread running in the background simulates another thread that might be trying to close or dispose the program and calls Close/Dispose on a different thread. Unfortunately, that thread will also block forever." 16530 area-Meta Ubuntu 16.10 CI runs failing These appear to be the first failing builds: https://ci.dot.net/job/dotnet_corefx/job/master/job/ubuntu16.10_debug/1095/ https://ci.dot.net/job/dotnet_corefx/job/master/job/ubuntu16.10_release/1098/ which suggests one of these changes is the culprit: ``` Changes Add Narrow, Widen, and Conversion methods to System.Numerics.Vectors.

The effect of these statements is (with clang 3.9.1) that the `${SYSROOT}/usr/include` folder (where curl and openssl headers reside in a Yocto build environment) becomes an `-isystem` parameter to clang and this reorders that folder above the C++ include folders. When clang now tries to resolve C++ header files, it fails on an `#include_next `, because that file isn't found in a folder that comes after the C++ header folders. Blaming the two CMakeLists points to build issues for OSX and BSD, but I cannot build for those targets. Otherwise I would check if the entire `include_directories` statement is actually necessary, or if removing the `SYSTEM` argument still makes the build succeed (it should).

This is the expected behaviour. This exception is thrown by a code in `SerialStream.Write`, which looks like this: ``` if (numBytes == 0) throw new TimeoutException(SR.Write_timed_out); ``` Where `numBytes` is passed back from the OS in the `lpNumberOfBytesWritten` argument of `WriteFile`. With some usb serial devices (tested with FTDI) `lpNumberOfBytesWritten` is not zero in this situation - it's some non-zero number less than the size of the buffer which was written. It's probably related to the difference in size between the buffer written and the amount of internal buffering within the driver/hardware stack.. This might be characterised as a bug within the FTDI product, but it's probably very difficult to fix - they have committed a certain amount of data to the USB stack and their hardware device, and once that's gone from their serial driver it is hard to know that it never made it out of the pins of the IC at the end of the USB cable. It could be possibly made to work via reporting back from the hardware to the driver, but if that isn't in place in their existing protocol then it's probably not going to be. This gives a situation where a `Write` has failed with a timeout but this fact is not visible to the application. Instead of the `numBytes == 0` test, we might consider having some other way of determining that a timeout occurred - perhaps something like `numBytes < (bytesThatCouldbeWritten)`. I'm not currently sure what `(bytesThatCouldbeWritten)` would be, and how this would interact with overlapped writes, etc, but it's worth thinking about. This can be left up-for-grabs for now. 16543 area-System.IO Fix testsharedframeworkpath for windows build-native. resolves https://github.com/dotnet/corefx/issues/15981 @mellinoe 16544 area-System.Net Increase Ping test timeout.

On Windows that seems to work fine (that other loopback port is never in use), but on Unix (and OSX) port #'s are random (not incremental as in Windows) and it treats IPV4 and IPV6 as separate addresses thus the expected unused port will occasionally be in use causing that test, or related test to fail. Most likely it is the 'mirror' test that is using the other protocol+port, meaning the test just before or after the current test that for example tests (IPV6, IPV4) while the original tests (IPV4, IPV6). I have repro'd the failures fairly consistently on Ubuntu by adding a 'for' loop to both tests so they execute 1,000 times or so. I have also written a small POSIX example that shows given a bound IPV6 loopback port, the OS can return an IPV4 address with the same port. This PR just disables these tests for non-Windows cases. Note that these are also the 'failure' tests, meaning the happy path tests (IPV6, IPV6) or (IPV4, IPV4) are not changed here.

Some tests have been assuming that when a local reference (e.g. a local variable) is last used in a method, it is immediately available to be collected by the GC, but this was never guaranteed (it just happened to work that way most of the time) and with upcoming CoreCLR changes this assumption will break tests. This change moves such references into their own method bodies - this is still not 100% guaranteed to work but it's very hard to see it ever breaking in the real world. 16555 area-System.Numerics "Test ""System.Numerics.Vectors.Tests "" failed with System.Reflection.TargetInvocationException & System.AccessViolationException" Detail: https://mc.dot.net/#/product/netcore/master/source/official~2Fcorefx~2Fmaster~2F/type/test~2Ffunctional~2Fcli~2F/build/20170228.02/workItem/System.Numerics.Vectors.Tests/wilogs Failed test: System.Numerics.Vectors.Tests Failed to generate the test result.

For my bachelor thesis project I already need this library very soon - a nightly/experimental/pre-alpha/whatever - build is perfectly fine though. My question now is, what are the steps to include the project in the corefx packaging process? I did some hands-on and research but did not get far with it. Is there some kind of checklist for this? If not, could someone explain it to me so that I can include it by myself? I'm asking because I don't expect the package to be available on myget in time.

"The SZ array type (""T[]"") and rank 1 multidim arrays (""T[*]"") are distinct and non-interchangable types in .NET. However, the Reflection surface area contains no api to distinguish. (The most ""obvious"" approach (""t is Array && t.GetArrayRank() == 1"") captures both.) Proposal: Add a new property to System.Type: ```c# public virtual bool IsSZArray { get { throw NotImplemented.ByDesign; }} // Subclass needs to implement ``` Alternate names that have been proposed: IsSZArray IsVector The name ""IsSzArray"" has the small advantage that it already exists in both CoreClr and CoreRt - it's just not public. " 16567 area-System.Reflection Proposal: Update Type.GetMethod() overloads to simplify finding generic methods via reflection "# Problem Currently it is quite burdensome to resolve a specific `MethodInfo` for a generic method. That requires looping through all of the methods of the type and manually determining candidates based on name, parameter arity, type compatibility, etc. Such home-grown solutions are generally fragile, making assumptions regarding the specific overloads available for a given generic method at that point in time. # The problem with Type.GetMethod() `System.Type` exposes various apis for retrieving methods by signature. In the end, all of them are wrappers around this single method: ` public MethodInfo GetMethod(string name, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers) ` This api was adequate in a pre-generics world. Once generics appeared however, the api has two serious defects: ### 1. You cannot specify the generic arity. According to ECMA 335, the method signature includes the method's generic arity (generic parameters introduced by the method itself - not to be confused with generic parameters on the type declaring the method.) It is fully possible to have two methods on a type that differ only by generic arity. Despite this, there is no way to constrain the search to a specific generic arity. ### 2. No easy way to specify a generic parameter reference in a signature. To disambiguate between overloads, the api takes an expected signature in the form of a `Type[] `array. The problem is that Type objects in Reflection represent ""resolved types"" rather than ""signature types."" Nevertheless, in a pre-generics world, this was a reasonably adequate way to represent a signature type. However, generics added a new signature type known as the generic parameter reference (ET_VAR/ET_MVAR) which throws a wrench into this scheme. Information-wise, an ET_MVAR is a mere integer (the position index of the generic parameter being referenced.) Unfortunately, the `Type` model in Reflection has no direct analog to this simple construct. Instead, the only option available today to pass in a fully resolved generic parameter _definition_ `Type`, which includes back references to `MethodInfo` that introduced it, a name, the constraints, a metadata token -- the works. For generic method parameters, this creates a chicken and egg problem for the `Type.GetMethod()` api. To unambiguously retrieve a generic method such as this: ` void Foo(T t) {} ` you to have pass in the fully resolved `Type` object for ""T"". But the only way to obtain that is by calling `GetGenericArguments()` on the `MethodInfo` for `Foo`. In other words, **you must already have the method you're looking for in hand before you can call the `Type.GetMethod()` to find it.** # Proposal Part A: Introduce a `genericParameterCount` parameter. On `Type`, introduce the following public overloads: ``` public MethodInfo GetMethod(string name, int genericParameterCount, Type[] types) public MethodInfo GetMethod(string name, int genericParameterCount, Type[] types, ParameterModifier[] modifiers) public MethodInfo GetMethod(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, Type[] types, ParameterModifier[] modifiers); public MethodInfo GetMethod(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers); ``` and the protected overload (which all of the above funnel to): ``` protected virtual MethodInfo GetMethodImpl(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers) => throw new NotSupported; ``` `genericParameterCount` can be any non-negative integer and constrains the search to methods with that generic arity. (In particular, if `genericParameterCount` is 0, the search is constrained to non-generic methods.) The candidates are filtered for generic arity before the binder (if supplied) is invoked. # Proposal Part B: Provide a way to create a `Type` that represents a bare generic parameter reference and constructed types involving them. On `System.Type`, introduce a new static method: ``` public static Type MakeGenericMethodParameter(int position); ``` This method returns a special ""Signature Type"" object that can be passed into `Type.GetMethod()`'s `Type[]` array to represent an ET_MVAR. ## Sample Usage Take this horror show of a type: ``` class Horror { public void Moo(int x, int[] y) {} public void Moo(T x, T[] y) {} public void Moo(int x, int[] y) {} public void Moo(T x, U[] y) {} // <-- We want this one instantiated to ""Moo()"" public void Moo(int x, int[] y) {} } ``` Here's how to pluck this out safely and unambiguously using the new api: ``` Type horror = typeof(Horror); Type theT = Type.MakeGenericMethodParameter(0); Type theU = Type.MakeGenericMethodParameter(1); MethodInfo moo = horror.GetMethod(""Moo"", genericParameterCount: 2, new Type[] { theT, theU.MakeArrayType() }); MethodInfo mooOfIntInt = moo.MakeGenericMethod(typeof(int), typeof(int)); ``` ## `Type` members implemented by Signature Types. Signature Type objects will be very restricted in functionality with most of its members throwing NotSupportedExceptions. It's only purpose is to be used as a search pattern to discriminate between overloaded methods. The following are the apis that actually do something on Signature Types: **Type Compositors:** ``` public Type MakeArrayType(); public Type MakeArrayType(int rank); public Type MakeByRefType(); public Type MakePointerType(); ``` These create the appropriate constructed `Type` around the generic parameter reference. Types created this way have the same restrictions and also belong in the ""signature type"" universe. In addition, `MakeGenericType()` on regular types will be enhanced to accept Signature Types. If one or more argument to `MakeGenericType()` is a Signature Type, the returned type will also be a Signature Type. For performance (and code simplicity reasons), no constraint checking will be done on any of the generic type arguments. The Signature Type will never be used to construct an actual Type, after all, it is simply a pattern used to disambiguate overloads. **Type Flavor Identifiers** ``` public bool IsTypeDefinition; protected bool HasElementTypeImpl(); protected bool IsArrayImpl(); public bool IsSZArray; public bool IsVariableBoundArray; protected bool IsByRefImpl(); public bool IsByRefLike; protected bool IsPointerImpl(); public bool IsGenericType; public bool IsGenericTypeDefinition; public bool IsConstructedGenericType; public bool ContainsGenericParameters; public bool IsSignatureType; public MemberTypes MemberType; ``` (while we don't need all of these, they are all trivial to implement so we might as well keep this set ""safe to call."") **Type Dissectors:** ``` public Type GetElementType(); public int GetArrayRank(); public Type GetGenericTypeDefinition(); public Type[] GenericTypeArguments { get; } public Type[] GetGenericArguments(); public int GenericParameterPosition { get; } ``` This is the minimal set needed to do comparisons between signature types and the actual method parameter type. **Identity:** ``` public bool Equals(object o); public bool Equals(Type o); public int GetHashCode(); public Type UnderlyingSystemType => this; // Only because Equals(Type) has a dependency on this ``` We won't override `System.Object`'s implementations. In other words, these methods will work but have no particular utility value. At the moment, signature types are simply short-lived argument objects to `Type.GetMethod()`. If they never play a bigger role than that, we'll have saved ourselves from writing unnecessary memoization code and detailed equality routines. If they do become something more persistent in the future, we reserve the right to override and implement these to compute actual semantic equality. **Diagnostics:** ``` public string Name { get; } public string Namespace { get; } public string FullName { get; } public string AssemblyQualifiedName => null; public string ToString(); ``` For simple debugging/logging purposes, the `Name` property will emit strings like ""!!0"" and ""!!1"" (the long established ILASM syntax for ET_MVARS.) `Namespace` will return `null`. `FullName` and `AssemblyQualifiedName` will both return `null` (as all open types do.) Anything not mentioned above will throw a `NotSupportedException(""This operation is not supported on signature types."")`. If we find it useful to support additional apis later, this will leave that door open. ## Signature Types passed to other apis that take Types Signature Types are not recognized as ""runtime-implemented Types"" by apis that test for this (""if (type is RuntimeType)). Thus most apis will either throw at that point or hit a NotSupportedException eventually when it calls a non-supported member on type. There are several reasons for this separation: - The Types normally created by the runtime represent fully resolved types with assembly and container member info, not to mention executable IL, loader contexts and runtime application state (static fields.) Signature Types are simply search patterns that include none of those things, and potentially things that resolved types don't (for example, custom modifiers.) From a purist perspective, having the same object represent both is an overlap of concerns. From a pragmantic perspective, creating an entire new parallel Type class for Signature Types is probably going too far, given where .NET is at this point. However, we can at least minimize the issue by keeping the subset that doesn't fit into the ""resolved type"" model separate and restricted to the very limited purpose of passing them into `Type.GetMethod()` routines. - Implementing these as ""third party"" types means we can have a simple non-invasive implementation of them that's sharable between CoreCLR and CoreRT. In particular, we don't have to figure out how to represent them in the unmanaged area of CoreCLR (the latter would drastically reduce the chances of finding anyone to step up and implement this...) # Items not in scope but possible future extensions To keep the proposal to a reasonable size, these items are not in scope - however, we want to keep them in mind while designing this so as not to lock them out in the future. ## A SignatureType for generic parameters on types (ET_VAR) This is an obvious completeness addition. The usability difficulties that motivated this proposal don't apply to generic parameters on types so we don't need this right away. If this usage catches on, though, it would be good to have a consistent language for both types and method generics. This would imply adding the ability to pass Signature Types to the `Type.GetConstructor` and `Type.GetProperty` family of apis and the DefaultBinder methods that support them. For now, this is being left out of scope to keep the api proposal down to size. ## Third party binder/reimplementation support If we want third party binders to be able to recognize and act on these signature types, we'll need to add more surface area to enable that. For now, I'm keeping this out of the scope of the proposal until we've had some experience with this. ## Custom Modifiers Another obvious use of the Signature Type concept would to be a `MakeModifiedType(Type modifier, bool required)` method on `Type`. This would make it possible to disambiguate methods overloaded on custom modifiers. Since this is a completely different usage scenario, it is not in scope here. # Summary of Additions ## Two new api on `System.Type`: ``` public static Type MakeGenericMethodParameter(int position); public virtual bool IsSignatureType => false; ``` Returns a Signature Type representing a reference to a generic parameter on the method. `ArgumentException` if `position < 0`. ## New api overloads on `System.Type`: ``` public MethodInfo GetMethod(string name, int genericParameterCount, Type[] types) public MethodInfo GetMethod(string name, int genericParameterCount, Type[] types, ParameterModifier[] modifiers) public MethodInfo GetMethod(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, Type[] types, ParameterModifier[] modifiers); public MethodInfo GetMethod(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers); protected virtual MethodInfo GetMethodImpl(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers) => throw new NotSupported; ``` **New Parameter:** `int genericParameterCount` **Behavior:** Causes `GetMethod()` to disregard methods whose generic arity does not match the specified value. If `genericParameterCount` is 0, disregard all generic methods. This filtering is done before the binder, if supplied, is called. **Exceptions:** `ArgumentException` if `genericParameterCount < 0` ## New behavior for `System.Type.MakeGenericType()` on regular `Type` objects: If one or more arguments to `MakeGenericType()` is a Signature Type, the method switches to the new behavior and constructs a Signature Type. No constraint checking is done (even on the types that aren't signature types.) **Exceptions:** `ArgumentNullException` if any of the parameters are `null`. `ArgumentException` if the number of supplied arguments does not match the number of generic parameters on the ""this"" Type. `InvalidOperationException` if `this.IsGenericTypeDefinition != true` ## New behavior for `System.Type.GetMethod(...)` and `System.Type.DefaultBinder`: The `Type[]` passed to indicate the target method signature can now include Signature Types. Overload discrimination will proceed _as if_ each generic parameter reference embedded within the Signature Type were replaced by the corresponding generic parameter definition introduced by the method being considered. # Reponses to previously asked questions **1. Can we change our implementation of GetMethod(...) to make it easier for instantiating generic methods?** Doing this now by adding a `genericParameterCount` argument that completes the ""missing piece"" of the signature specification. **2. Do we need new APIs?** Yes, when the generic method references its own generic type variables (ET_MVAR) in the signature. It is not practical to expect the caller to pass in a fully resolved generic parameter type since that requires him to have the very MethodInfo that he's looking for. Adding one new api to `System.Type` to create a lightweight Type object that wraps an index and nothing more. **3. Do we want to expose this policy at all or should the selection process be controlled by the consumer?** While I think the current GetMethod() apis have too much policy and complexity in them (binders), this proposal recognizes that these apis are well known and the proposed changes are straightforward extensions. More importantly, the changes introduce no new policy or fuzziness. ""Disregards all methods that don't match the specified generic arity and does so before calling the binder"" is crisp and objective. Similarly, the handing of signature types is ""binding and overloading resolutions occurs _as if_ you'd passed in the actual generic parameter from the method being considered."" So we're not introducing new semantics there - only a saner way of invoking the existing semantics. **4. How do you conceive this proposal working for the overloads that takes the binder?** For part A, binders will receive only those candidates that match the supplied `genericParameterCount.` For part B, binders (other than the DefaultBinder) will receive a Type array with signature types in them that they won't know what to do with. Applications calling these methods with custom binders will have to stick to passing in regular old Types. I think the non-custom binder case is common and useful enough not to block them on this. If we think the custom binder case that that important, the proposal can be extended if necessary to expose the necessary surface area for custom binders to recognize and act on signature types. (It'll be the internal surface area we implement for the DefaultBinder's use.)

When no keychain is given, SecKeyGeneratePair will generate the keys into the default/login keychain. Since the keys were not expected to have been in the keychain, they permanently leak out and the keychain grows over time. Instead, have the managed code provide a temporary keychain into which the keys will be created. Then, export them and re-import them to the NULL keychain. The temporary keychain can then be deleted, and the hard problem of delayed cleanup is avoided. Files on disk will still leak if the process terminates during the key generation phase, but that is a much smaller window than other 'temporary file on disk' solutions. 16589 area-System.Data Managed SNI for Windows The changes include refactoring in SqlClient to build Managed SNI on Windows along with Native SNI.

In fact, we have FXCop rules like [CA1305](https://msdn.microsoft.com/en-us/library/ms182190.aspx) that flag non-explicit use. String interpolation in C# follows what virtually all our formatting APIs do unless instructed otherwise: it will format the string using the current culture. While we have `FormattableString.Invariant`, which allows customers to use the invariant culture, like so: ```C# string text = FomattableString.Invariant($""This will be formatted using invariant {i}""); ``` We don't have a way in string interpolation to explicitly indicate that we intend to use the current culture. This proposes an API to allow that. It would be a way to suppress FXCop rule CA1305. ### Proposal ```C# namespace System { public partial class FormattableString { // Existing API: // public static string Invariant(FormattableString formattable); public static string CurrentCulture(FormattableString formattable); } } ``` ### Usage ```C# // These are now equivalent string text1 = $""This will be formatted using current culture {i}""; string text2 = FomattableString.CurrentCulture($""This will be formatted using current culture {i}""); ``` /cc @gafter " 16622 area-System.Security using pool for buffer in HashAlgorithm this creates new 4K buffer every time computing hash https://github.com/dotnet/corefx/blob/e9ecf74d845476540f40fa8fdc62c53ebf048519/src/System.Security.Cryptography.Primitives/src/System/Security/Cryptography/HashAlgorithm.cs#L78 which is probably fine when creating hash for 1 or 2 values. but when creating large numbers of hashes that adds up quite quickly. one of examples of those cases will be C# compiler compiling that need to create SHA1 hashes for all source files and many more for pdb and other identifies. pooling that buffer seems easy allocation win. 16625 area-System.Net Improve CI: disable WebSocket test ReceiveAsync_Cancel_Success "Disable test that has been failing every few days: https://github.com/dotnet/corefx/issues/13302 It is failing because the test verifies the exact WebSocketException exception string which does not always match.

On windows, Serialize and Deserialize take a similar amount of time.

This proposal rely on this suggestion and tries to solve ambiguous semantic of `ICollection.IsReadOnly` property. We needs a new property. ```CSharp public interface IReadOnlyCollection { bool IsImmutable { get;} } public interface ICollection { bool IsImmutable { get;} } public interface IReadOnlyDictionary { bool IsImmutable { get;} } public interface IDictionary { bool IsImmutable { get;} } ``` Let suppose we have two different collections both inherited from ICollection<T> First example is when library allows to access some internal collection by the interface. ```CSharp internal class PrivateCollection: ICollection { // Read methods allowed for library and for external usage. bool Contains(T item) { // Some valid implementation. } // This method is only allowed for some library internal classes. internal void Add(T item) { // Some valid imiplementation. } // Modification is closed for external users, but not for internal. void ICollection.Add(T item) { throw new NotSupportedException(); } public bool IsReadOnly { get { // In this case true mean - this collection allowed to only read from ICollection // interface. // But does not guaranties that collection will not be changed by some internal method. return true; } } } ``` this is ReadOnly meaning of IsReadOnly property. --- Second collection can be well known ImmutableList ```CSharp public class ImmutableList: ICollection { bool ICollection.IsReadOnly { get { // Here it tells that collection is not only ""ReadOnly"" but also will never be changed by nobody. return true; } } } ``` Probably ""it's too late"" and we have tons of code one collections uses ReadOnly semantic another Collections uses ReadOnly+Immutable semantic. But now we can do the next improvement in the documentation: IsReadOnly says that only: all mutation method will return NotSupportedException or InvalidOperationException. And no any more guaranties. " 16661 area-System.Collections Proposal: Add full family of Immutable collection contracts. "```C# public interface IImmutableEnumerable: IEnumerable {} public interface IImmutableCollection: IReadOnlyCollection, IImmutableEnumerable() public interface IImmutableListSlim: IReadOnlyList, IImmutableCollection{} public interface IImmutableSetSlim: IReadOnlySet, IImmutableCollection() public interface IImmutableDictionarySlim: IReadOnlyDictionary, IImmutableCollection>{} // also improve public interface IImmutableList: IImmutableListSlim{} public interface IImmutableArray: IImmutableListSlim{} public interface IImmutableSet: IImmutableSetSlim{} public interface IImmutableDictionary: IImmutableDictionarySlim{} ``` Motivation: ```CSharp public class MyClass { public MyClass(IReadOnlyList someIds) { // Currently I cannot rely that someIds will never change. // I every time think: should I copy this collection or I can use it as-is. // Ok, it's not a trouble I can copy, but stop, what if this place will be performance critical ??? // no I don't want to copy. // Let assume nobody will never change this collection. <== TOTALLY WRONG! SomIds = someIds; // also I performed some loading based on this ids. // and store result in the instance. // ids list will be hardly used by this component and consumers of this components. } public IReadOnlyList SomeIds {get;} } // Some other place, some newbie developer... public void SomeCreationPlace() { // ... // Some algorithm with bugs. var ids = new List(); while (someCondition) { for(int i = 0; i++; i { public IEnumerator GetEnumerator() { throw new NotImplementedException(); } IEnumerator IEnumerable.GetEnumerator() { return GetEnumerator(); } public int Count { get { throw new NotImplementedException(); } } public int this[int index] { get { throw new NotImplementedException(); } } public IImmutableList Clear() { throw new NotImplementedException(); } public IImmutableList Add(int value) { throw new NotImplementedException(); } public IImmutableList Replace(int oldValue, int newValue, IEqualityComparer equalityComparer) { throw new NotImplementedException(); } public IImmutableList SetItem(int index, int value) { throw new NotImplementedException(); } public IImmutableList RemoveAt(int index) { throw new NotImplementedException(); } public IImmutableList RemoveRange(int index, int count) { throw new NotImplementedException(); } public IImmutableList RemoveRange(IEnumerable items, IEqualityComparer equalityComparer) { throw new NotImplementedException(); } public IImmutableList RemoveAll(Predicate match) { throw new NotImplementedException(); } public IImmutableList Remove(int value, IEqualityComparer equalityComparer) { throw new NotImplementedException(); } public IImmutableList InsertRange(int index, IEnumerable items) { throw new NotImplementedException(); } public IImmutableList Insert(int index, int element) { throw new NotImplementedException(); } public IImmutableList AddRange(IEnumerable items) { throw new NotImplementedException(); } public int LastIndexOf(int item, int index, int count, IEqualityComparer equalityComparer) { throw new NotImplementedException(); } public int IndexOf(int item, int index, int count, IEqualityComparer equalityComparer) { throw new NotImplementedException(); } } } ``` Really too heavy. I do not want Add(), Remove(). I just what IReadOnlyList + Immutability guaranty. CURRENTLY WE HAVE NOTHING. We can introduce slim immutable contracts (with usual hierarchy): ```CSharp public class MyClass { // No comments all clear. public MyClass(IImmutableListSlim someIds) { SomIds = someIds; } // This collection instance can travel across components, threads, call chains safely. public IImmutableListSlim SomeIds {get;} } ``` " 16662 area-Microsoft.CSharp CSharpCodeGenerator outputs sealed override methods as virtual "CSharpCodeGenerator will output a method with Attributes of `Public`, `Final` and `Override` as a virtual method.

Consolidate into a single property. While `size` is the most heavily used and `Count` the least, `Count` is the most .NET idiomatic, so leave it as the sole property. Has both `Item()` method and indexer. Replace use of `Item()` with use of indexer, and remove `Item()` method. Debug-only `AssertValid()` method can be made conditional rather than wrapped in `#if`/`#endif` for cleaner use. While this means it will be compiled to the release build rewriting the assertion within it to be a single linq operation means it will be compiled as an empty method for those so the cost in IL size is much less than the savings made above. Optimise: `HasErrors` property is hard-coded to return false and therefore of not really checking anything. Remove. All uses of `ToArray()` do not mutate the resultant array so exposing the `_items` field as a public `Items` property is safe, and avoids many allocations and copies. Constructor is never called with null, so remove null path, but assert that null isn't passed. 16664 area-Microsoft.CSharp Make Microsoft.CSharp use the coding style more like the rest of corefx I've already done some changes along these lines, though mostly when there was another benefit (if often a pretty tiny optimisation if considered solely as such). Having been ported from C++ code has left its mark in some strange constructs, unconventional names, Get/Set method pairs instead of (or as well as) properties, etc. I don't know about anyone else, but I think I would have found the fixes at #15397 and #16085 a lot quicker than I did if the code more closely followed common C# conventions. This issue is to track changes to make the coding style more usual, which I intend to do in earnest once I've finished #8081 as my current long-burner issue. I intend to do so incrementally as one massive PR would be a nightmare to review. This also gives anyone who can think of a good reason for leaving alone somewhere to say so. In particular, I'm assuming that dead code (there are some entirely dead types in there) originates from the static compiler it was ported from having cases that don't arise with dynamic code. Can someone confirm this, rather than there being another reason — e.g. some code wasn't ported from the desktop version — and hence a reason to leave that dead code in there? 16665 area-System.Security System.Security.Cryptography.Xml failing tests These two tests are failing outerloop (apparently multi-use problems with dtd file) System.Security.Cryptography.Xml.Tests.XmlDsigC14NWithCommentsTransformTest.C14NSpecExample1_WithoutResolver (from (empty)) ``` Failing for the past 1 build (Since Failed#116 ) Took 4 ms.

More details can be found [HERE](https://github.com/PowerShell/PowerShell/issues/3040) which is where I filed the original bug with the PowerShell team, and also [HERE](https://github.com/dotnet/coreclr/issues/9854) as the PowerShell team directed me to CoreCRL, who have since directed me here to CoreFX... I'm hoping this is the right place... This is assuming the use of a system PAC file such as: ```c# function FindProxyForURL(url, host) { if ( host == ""www.msn.com"" ) { return ""PROXY 10.10.10.10""; } else { return ""DIRECT""; } } ``` Problem code: ```c# void Main() { System.Net.WebClient client = new System.Net.WebClient(); Uri uri_absolute = new Uri(""http://www.msn.com"", System.UriKind.RelativeOrAbsolute); Uri uri_relative = new Uri(""www.msn.com"", System.UriKind.RelativeOrAbsolute); Console.WriteLine(client.Proxy.GetProxy(uri_absolute).Host); try { client.Proxy.GetProxy(uri_relative); } catch { Console.WriteLine(""Exception""); } Console.WriteLine(client.Proxy.GetProxy(uri_absolute).Host); } ``` And the output is: ``` 10.10.10.10 Exception www.msn.com ``` It should be: ``` 10.10.10.10 Exception 10.10.10.10 ```" 16696 area-Meta Some libraries are building implementations for platforms they don't run on eg System.DirectoryServices.Protocols has a single configuration in Configurations.props ``` xml netstandard-Windows_NT; ``` This is a Windows specific implementation but as authored it is building that as a generic IL implementation (despite the Windows_NT prefix ) For platforms it doens't currently support (UAP, Unix) it should be building and packaging a PNSE assembly presumably with an appropriately conditioned property in the project.

This PR introduces RIDs for Android. Some remarks: - Because Android uses the Linux kernel, I've chosen to make Android import Linux. Just like Alpine Linux, Android uses a different C runtime (bionic), so chances this will always work are slim. - At the moment, CoreCLR and CoreFX support arm and arm64 Android, so I've left out x86 and x64 Android (although they make make great candidates for testing as they can be virtualized on x64 hardware) - Android versions by ""API levels"", so you have API level 1, 2, 3,... . I've chosen to make API level 21 explicit, because it is the first API level that also support arm64. At the same time, the CoreCLR and CoreFX builds use packages borrowed from Termux (I like to think of Termux as a package management system for Android, similar to brew on macOS).

It would make code cleaner because sometimes we just want to append some variable into collection Just add this to Enumerable extension method ```C# public static IEnumerable Concat(this IEnumerable first,params TSource[] second) { return first.Concat(second as IEnumerable); } var zeroToHundred = Enumerable.Range(0,100); var zeroToHundredPlusOne = zeroToHundred.Concat(101); ``` Also, would it be better if we have `Append` and `Prepend` instead? ```C# public static IEnumerable Append(this IEnumerable items,params TSource[] after) { return items.Concat(after); } public static IEnumerable Prepend(this IEnumerable items,params TSource[] before) { return before.Concat(items); } var oneToHundred = Enumerable.Range(1,99); var zeroToHundredPlusOne = oneToHundred.Prepend(0).Append(101); ``` 16743 area-System.Numerics Extension method to number I think it would be useful if number have some extension method as helper in many trivial function instead of static class First I would like to suggest `To` and `Range` ```C# namespace System.Linq; public static IEnumerable To(this int start,int end) { var sign = Math.Sign(end - start); end += sign; while(start != end) { yield return start; start += sign; } } public static IEnumerable Range(this int start,int count) { return Enumerable.Range(start,end); } ``` The usage will make code more compact and easier to write ```C# foreach(var i in 1.To(100)) Console.WriteLine(i); foreach(var i in 1.Range(99)) Console.WriteLine(i); ``` Second. I would like to suggest that, most of `Math` and `DateTime` should move into `System.Numerics` as an extension method to number itself for example ```C# namespace System.Numerics; public static double Pow(this double value,double power) { return Math.Pow(value,power); } public static float Pow(this float value,float pow) { return (float)Math.Pow(value,power); } public static TimeSpan AsMilliseconds(this long millisec) { return DateTime.FromMilliseconds(millisec); } public static TimeSpan AsMilliseconds(this double millisec) { return DateTime.FromMilliseconds(millisec); } ``` Same as above ```C# var sqrt2 = 2f.Pow(0.5f); var timeSpan = 1000L.AsMilliseconds(); ``` Both of these proposal should be contained in namespace. So it would be hidden unless explicit using, would not hamper in normal life 16744 area-System.Net Socket.Select / Read and Socket.Handle @samirparekh commented on [Thu Sep 29 2016](https://github.com/dotnet/coreclr/issues/7413) Hi, we have an application which we intend to port to .NETCore. This application is a latency sensitive application and it requires to monitor >100 sockets for incoming (high frequency) financial market data. I have gone throught the implementation of Socket.Select for windows and Linux (from the available source code). It seems like for Linux the framework allocates a stack based pointer list (in case when the provided socket list length is < 80) else on the heap. Surprising enough the same approach could have benefited wider group of windows users. Moreover in my case where i can not go for allocating an array of >100 sockets , in my previous implementation I had a pre-allocated array/list of socket pointers/handles and reused it through the process lifecycle(thus eleminating the performance penalty imposed by GC in case of constantly re-allocating IntPtr arrays). It seems like in the current code base it is no longer possible to get an IntPtr / handle to a socket which makes the above code optimization impossible. May I request you (in the interest of broader community) to rethink the various scenarios and advice the possible cource of action.

These are useful because they provide a way to write certain conditions very succinctly. The only such property missing is `IsCompletedSuccessfully`. It should be added. The workarounds are a little awkward: `t.Status == TaskStatus.RanToCompletion` and `!t.IsFaulted && !t.IsCanceled`. They are longer, don't express meaning well and sometimes are written incorrectly (e.g. forgetting about cancellation). Is there a reason `IsCompletedSuccessfully` can/should not exist? --- @omariom commented on [Sat Aug 13 2016](https://github.com/dotnet/coreclr/issues/6732#issuecomment-239626805) `IsSucceeded`? --- @benaadams commented on [Sat Aug 13 2016](https://github.com/dotnet/coreclr/issues/6732#issuecomment-239629098) `IsCompletedSuccessfully` would match `ValueTask` which has it https://github.com/dotnet/corefx/blob/master/src/System.Threading.Tasks.Extensions/src/System/Threading/Tasks/ValueTask.cs#L135-L136 --- @GSPP commented on [Sat Aug 13 2016](https://github.com/dotnet/coreclr/issues/6732#issuecomment-239629282) Yes, I think Task and ValueTask should have as much common surface area as possible to make it easy to switch between the two. It might even make sense to add a `Status` property to `ValueTask` and synthesize a suitable status in case the object is not based on a task. --- @jamesqo commented on [Sun Aug 14 2016](https://github.com/dotnet/coreclr/issues/6732#issuecomment-239733437) Since `ValueTask` has it, 👍 from me.

I believe there is a thread discussing this already but the the dependency on CURL is problematic. It causes and will continue to cause a few basic issues such as this one. https://github.com/dotnet/coreclr/issues/9953 Over time the Curl dependency will become more pronounced as interfaces change. Eventually, there will be some sort of breaking change that will cause your users (like me) subtle and/or obvious problems such as software ceasing to work, or unwanted (but needed) system updates to non .NET software. The ""fix"" for this particular issue may be a static dependency. There are other reasons though... A byproduct of the CURL dependency is that the behavior of the HttpClient is handicapped. We cannot retrieve an underlying network stream from the HttpClient and do with it as we wish. Access to the stream is hidden within curl. Rich signaling of error conditions and network state are not possible as a result. Finally, there is also some overhead associated with pinvoke and the interop. We cannot say the current implementation is the most efficient way to make these requests. I would propose a higher performance, ""lighter weight"" client with better underlying network access and memory usage our current implementation. ### Improvement 2 - Synchronous methods In some scenarios I would like to be sure that I know what my code is doing. There are times, such as trying to design a process that is well understood and verifiable, where placing that code in a thread and running it to completion (or forever) is a desirable attribute. Fundamentally, the use of the await keyword introduces code that the developer does not write. After having spent the last 8 months developing on Linux with just the VS Code debugger - debugging complex threading issues is very difficult and time consuming. Finally the inclusion of the HttpClient forces me to change the overall structure of my service if it is primarily Synchronous in nature. ### Improvement 3 - Better indication of proper usage Creation of the HttpClient through ""new"" to make an individual requests is not recommended, but it is easy to do and seemingly correct since there are no API features to prevent us from making the mistake. TIME_WAIT socket growth is also not an expected behavior if I call ""Dispose"" on the HttpClient. Perhaps implementing a HttpClientPool with the ability to retrieve named instances of an http client and hiding the constructor for the HttpClient? The importance of the HttpClient to the .NET Core framework cannot be understated. It one of a handful of mechanisms to communicate outside the CLR, is the only Http based mechanism we have to complete REST operations. It must work well now and into the future for developers and organizations to continue to adopt .NET Core as a development and deployment platform. --- @stephentoub commented on [Mon Mar 06 2017](https://github.com/dotnet/coreclr/issues/9984#issuecomment-284501248) Thanks, but as a meta-point with regards to the title of this issue, I'm not sure how this is Linux-specific. (2) and (3) are about the shape of HttpClient, and (1) is simply about having a managed implementation rather than relying on a native implementation, e.g. libcurl on Linux or WinHttp on Windows. --- @stephentoub commented on [Mon Mar 06 2017](https://github.com/dotnet/coreclr/issues/9984#issuecomment-284503019) (1) We are considering a managed HttpClientHandler implementation. The core of that isn't challenging. The challenging part is feature parity, e.g. support for Negotiate/Kerberos/NTLM, support for HTTP/2, etc. Nothing insurmountable, just a lot of work before it could be substituted in silently. In the meantime, we are considering putting out a prototype of a managed implementation on corefxlab, that folks could play with, contribute to, and even use if they desired. (2) If this is about ease of us, you can't just block on the resulting Tasks, e.g. .Wait(), .Result, or .GetAwaiter().GetResult()? That would impact scalability, but you wouldn't want to use synchronous methods if scalability were an issue anyway. There was also already an issue about this: https://github.com/dotnet/corefx/issues/13813 If you want to continue this discussion, probably best to do it there. (3) Feel free to propose an API. I suggest splitting this issue up, though, as it's difficult to have a reasonable discussion about multiple, largely-unrelated issues in the same thread. I suggest closing this issue, using existing issues or opening new issues in the corefx repo for each constituent piece.

There are many string-like data structures, however, that give random access to immutable sequences of characters without the characters being in contiguous memory. **Rational and usage:** As things stand, the API & implementation for the VS TextBuffer is complicated because we need two versions of several methods: one that takes a string and one that takes our piece table. Having string implement `IReadOnlyList` would eliminate the need to duplicate the methods (and the while overhead of calling the character indexer via a virtual method is annoying it isn't critical in most of our scenarios since users rarely paste in megabytes of text). **Proposed change:** Change the signature of String from this: ``` c# public sealed class String : IComparable, ICloneable, IConvertible, IComparable, IEnumerable, IEnumerable, IEquatable ``` to this: ``` c# public sealed class String : IComparable, ICloneable, IConvertible, IComparable, IEnumerable, IEnumerable, IEquatable, IReadOnlyList ``` And add an implementation for `int IReadOnlyList.Count {get;}.` A more challenging request would be to have string implement something slightly more robust than `IReadOnlyList` which would provide some useful methods that avoid some of the performance issues (specifically, allowing a Substring-like capability and a copy ability that wouldn't have the overhead of going through the character indexer for each character). ``` c# public interface ISubsetableReadOnlyList : IReadOnlyList { ISubsetableReadOnlyList Slice(int start, int length); public void CopyTo(int sourceIndex, T[] destination, int destinationIndex, int count); } ``` It would also be convenient of ReadOnlySpan also implemented IReadOnlyChar (or ISubsettableReadOnlyList) so it could be used in scenarios where the consumer doesn't require the elements to be in contiguous memory. 16787 area-System.Memory Adding Span IndexOf that takes an index and count 16788 area-Serialization XmlSerializer to Support IXmlSerializable Types IXmlSerializable is available in NetStandard2.0.

It is not possible to implement them in portable .NET code today because there is no process wide memory barrier API that is a key primitive used to implement them. The proposal is to add system process wide memory barrier API.

If you look how System.IO.BinaryReader uses Read you see how It wraps around this inconsistency. https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/IO/BinaryReader.cs#L637 However this means It makes BinaryReader unable to work with a NetworkStream(in theory) because a NetworkStream may return 0, while the end of the stream is not reached.

After that proposal got approved, you can check whether a `System.Type` is a multidim array by writing `type.IsArray && !type.IsSZArray`. This check is rather awkward. We used to have this kind of API surface in the CoreRT type system, but it lead to problems with readability of the code that used the API. We ended up adding an IsMDArray property to the type system - refer to dotnet/corert#1925 to see how it improves readability (it lead to substantial improvements in readability in places that were dealing with arrays and the `IsArray` part was implicit, but we needed to do something special for MD arrays - `IsMDArray` captures the intent better than `!IsSZArray`) Proposal: Add a new property to System.Type: ```csharp public virtual bool IsMultiDimensionalArray => IsArray && !IsSZArray; ``` 16838 area-Infrastructure Update BuildTools to 1.0.27-prerelease-01407-02, include symbols in packages /cc @weshaggard @ellismg @ericstj 16839 area-Serialization TypeInitialization_Type_NoTypeAvailable in Serialization Tests When running on Uapaot, many of serialization tests failed on `System.TypeInitializationException`.

The result is that such comparisons are usually done on a byte by byte basis or even worse Enumerable.SequenceEqual, which performs really slow. ## Suggested APIs: ```c# class static SpanExtensions { static int SequenceCompareTo(this ReadOnlySpan first, ReadOnlySpan second); } ``` ## Design It would fit along nicely with other memory functions defined in Buffer such as memcpy or memmove. The arrays would have to be primitives and can be efficiently compared. ## Implementation Different implementations can be used for different lengths. Here are some examples: * Jump tables like [this](http://source.dot.net/#System.Private.CoreLib/src/System/Buffer.cs,276) for lengths <= 16 * comparisons in long*'s on x64, int*'s on x86 for shorter arrays * using SIMD-Enabled Vector Types for medium/longer arrays * CLR memcmp InternalCall for longer arrays.

On Unix I would expect certificate extensions such as .der or .pem, similar to the ones in OpenSSL's store.

More of a question really because I'm not very familiar with `ConditionalWeakTable`, but from what I understand it can store key/value entries in such a way that the entries don't have to be kept alive. It also says [on MSDN](https://msdn.microsoft.com/en-us/library/dd287757(v=vs.110).aspx#Anchor_7) that the type is thread-safe. Given that `SyncRoot` is a rarely-used property (if I remember correctly @mikedn told me it was baggage from .NET Framework 1.0), maybe it would be beneficial to store it in a static `ConditionalWeakTable` separate from the object? e.g. ```cs class List { object ICollection.SyncRoot => SyncRootTable.GetSyncRoot(this); } static class SyncRootTable { static readonly ConditionalWeakTable s_table = new ConditionalWeakTable(); static object GetSyncRoot(object key) => s_table.GetValue(key, _ => new object()); } ``` 16887 area-Infrastructure Updating the Windows build instructions to clarify the requirements for VS2017.

(The Port is closed) I'm trying to send AT Commands using `SerialPort` class. I'm using `SerialPort.GetPortNames()` to get all available ports. I'm trying to open a serial port for modem and getting its BaudRate through `SafeFileHandle` and `kernel32.dll` with `CreateFile` and `GetCommProperties` method. It was good until I encountered `InvalidOperationException`. It was raised when I'm trying to read from `Read` or `ReadExistingByte` method then accidentally the port was removed. I call `Close` and `Dispose` method. Then I plugged again the modem. But when I try to get BaudRate again to connect to modem for the same port(without exiting execution), now it says that the `SafeFileHandle` is invalid. The weird thing is when I call `SerialPort.GetPortNames()` (after removing port), it returns the comport that I removed. I think there is still some code in `SerialPort` that holds the port. Any ideas? **NOTE** Im able to access the port when I try to close current debugging session the start again.

It'd be nicer if we could simply write: ```C# ExceptionDispatchInfo.Throw(exception); ``` I propose we add the following method: ```C# public sealed class ExceptionDispatchInfo { public static void Throw(Exception source); ... } ``` Its visible behavior would be identical to using Capture/Throw, so a valid implementation would be: ```C# public static void Throw(Exception source) => Capture(source).Throw(); ``` but a more efficient implementation could be provided that didn't need to allocate an EDI, copy all of the Exception's state into it, and then copy all of the state back. 16897 area-System.Net unmanaged resource leak when HttpClient is not disposed "```c# [Test] public void Test() { TestInternal().Wait(); GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); dotMemory.Check(m => { Console.WriteLine(m.GetObjects(a => a.Type.Like(""System.Net.Http.HttpClient"")).ObjectsCount); //always 0 Console.WriteLine(m.GetObjects(a => a.Type.Like(""System.Net.Connection"")).ObjectsCount); //0 on Dispose(), 2 on Dispose(false) or without Dispose }); } private static async Task TestInternal() { var client = new HttpClient(); var s = await client.GetStringAsync(""http://msdn.com""); //client.Dispose(); /*client.GetType() .GetMethod(""Dispose"", BindingFlags.NonPublic | BindingFlags.Instance) .Invoke(client, new object[] {false});*/ } ``` ![a001a-clip-78kb](https://cloud.githubusercontent.com/assets/991922/23751339/e9da0ecc-04e1-11e7-9a34-99aed0636545.png) ![003ed-clip-185kb](https://cloud.githubusercontent.com/assets/991922/23751446/74d90988-04e2-11e7-9323-a00ea38e6813.png) HttpClient missing finalizer and Dispose(false) called from finalizer will do nothing" 16898 area-System.Net Audit System.Net throws losing stack traces There are a bunch of places throughout the System.Net libraries where exceptions are captured and later thrown, using `throw e;`. This overwrites their stack trace and bucket information, making it harder to diagnose problems when they occur. Over time we've chipped away at these, so there are many fewer now than there used to be, but some still remain. I've audited all of the System.Net libs, and fixed all the locations I found where this pattern was being employed, replacing them with usage of ExceptionDispatchInfo to avoid losing the call stack data. There are still some `throw e`s I left, but those were typically of a form where it was obvious no data would be lost, e.g. the exception was just instantiated a few lines earlier. There are likely also a few straggling cases, e.g. where `throw SomeFunction()` is used and `SomeFunction()` returns a cached exception instance, but we can address those on a case-by-case basis as we find them.

There is a test class that does this and when running it in desktop it just hangs forever because all the tests create an `HttpWebRequest` instance and call `GetRequestStreamAsync().GetAwaiter().GetResult()` -- [source code](https://github.com/dotnet/corefx/blob/master/src/System.Net.Requests/tests/RequestStreamTest.cs#L107-L112) the project test is `System.Net.Requests.Tests` I did this on a simple Console App targeting desktop: ```cs static void Main(string[] args) { for(int i = 0; i < 100; i++) { var request = GetRequest(); var stream = request.GetRequestStreamAsync().GetAwaiter().GetResult(); Console.WriteLine(stream.CanWrite); stream.Dispose(); //request.Abort() } } public static HttpWebRequest GetRequest() { HttpWebRequest request = HttpWebRequest.CreateHttp(new Uri("""")); request.Method = ""POST""; return request; } ``` And it will also hang. If I just enable `request.Abort()` when I'm done using the request it will stop hanging. I don't know if that is a good practice, but could be a workaround in the tests for desktop. If we change the `ServicePointManager.DefaultConnectionLimit` to be a 100 it would also fix it but I don't think that would be a good solution. After talking with @stephentoub he explained there was a difference in behavior in Core: > My guess here is that disposing of the request stream doesn't release the underlying connection that HttpWebREquest opens to the server, and that the only way to do that would be to then get the response and dispose of that. That's why changing the connection limit allowed you to get further, because the system wasn't throttling you to the two connections you already opened. On core, HttpWebRequest is built on top of HttpClient, and it's not going to actually open the connection until you've written all your data. That is why the test don't hang in Core.

Unlike https://github.com/dotnet/corefx/pull/16388 (which I reverted), this adds it in a new build leg. It still takes ~30 minutes to complete, but now it runs in parallel to package publishing and dotnet/versions updating. Letting dotnet/versions publish succeed even if this indexing leg fails is fine for `master` builds, but it could be a problem if it happened to a release/servicing build (and if we don't require all of a build's legs to be green to consider it release-worthy). In this worst case scenario, it's still possible to re-run this build leg or even index/archive the symbols manually, so I'm not concerned about it. I left the symbol publishing in the Windows leg active for now so we can compare what's indexed by both approaches and see what the gap is. 16940 area-System.Data SqlClient manual test run in the CI All the SqlClient tests in Manual Tests, which can be run in the CI, should be made to do so.

I noticed the thread before I `await`ed an `async` call and the thread when I was done were different. Ok, I guess this makes sense after reading about `SynchronizationContext`. However, the weird part is that things are continuing on the same thread that the `async` task was running on. That thread is reserved for processing async jobs, and so any blocking after the await in the original test code will cause that processing to lock. My implementation of this is [here](https://github.com/couchbase/couchbase-lite-net/blob/feature/api-v2/src/Couchbase.Lite/Support/SerialQueue.cs#L136). Roughly, it adds some logic to a queue and sets the result of a `TaskCompletionSource` when it is done. In terms of what I am saying above, the logic gets executed in `ProcessAsync` and then the test code continues **on the same thread that ProcessAsync is running** I inspected the `SynchronizationContext` of the thread at start, and determined that it is an XUnit library provided instance of [AsyncTaskMethodContext](https://github.com/xunit/xunit/blob/master/src/xunit.execution/Sdk/AsyncTestSyncContext.cs). If I understand correctly, without `ConfigureAwait(false)` the async state machine should post back to the original context when it is finished with its logic. In that case, this instance (I inspected `innerContext` to be null) will call [XunitWorkerThread.QueueUserWorkItem](https://github.com/xunit/xunit/blob/vs2017/src/common/XunitWorkerThread.cs#L29) which just adds to a default constructure `TaskFactory` instance. That seems to me that it should run on yet another thread and not the same one as before since the one from before is still executing stuff. I thought maybe the default changed to `ConfigureAwait(false)` so I tried running `ConfigureAwait(true)` but the behavior was the same. Is this a bug or the new behavior? --- @stephentoub commented on [Fri Mar 10 2017](https://github.com/dotnet/coreclr/issues/10082#issuecomment-285661409) When you write code like: ```C# var result = await t; ``` that logically translates into something like: ```C# var $awaiter = t.GetAwaiter(); if (!$awaiter.IsCompleted) { ... // stuff to hook up a continuation return; } Label: var result = $awaiter.GetResult(); ``` so if the thing you await is already completed by the time you await it, you will continue running synchronously on the same thread. This has always been the behavior, and ConfigureAwait doesn't influence that, i.e. ConfigureAwait doesn't force the await to always complete asynchronously, but rather controls the continuation behavior if it does complete asynchronously. --- @stephentoub commented on [Fri Mar 10 2017](https://github.com/dotnet/coreclr/issues/10082#issuecomment-285662040) Separately, in your code, Task.Factory.StartNew by default targets the current TaskScheduler, and it's up to the current TaskScheduler how to interpret and handle TaskCreationOptions.LongRunning. If your intent here is to force a new thread to be created as happens for LongRunning with the default scheduler, you should explicitly pass TaskScheduler.Default as the scheduler argument to StartNew; otherwise, if the context in which you're running has a TaskScheduler set up, you may not get the behavior you want (of course, maybe that's exactly what you want, but just wanted to call it out). 16974 area-System.Runtime Also include 'Visual Basic 2017' in the System.ValueTuple Package description.

Changing all existing 'async void' tests to 'async Task' to mitigate any potential side affects. FYI I added this temporary test to socket test class AccessAsync: ``` [Fact] public async void DoIt() { await new Task(() => { }); } ``` and then in all socket test runs after this, the tests hung after successfully running all 4 variants (from 4 Theory inputs) of System.Net.Sockets.Tests.SendReceiveApm.SendRecv_Stream_TCP_MultipleConcurrentReceives No specific tests were running when debugger attached to hung corerun process; I didn't debug further. This is a possible XUnit issue, although other test frameworks don't even allow 'async void' because it is difficult to get the test results back. FWIW XUnit apparently creates a different SynchronizationContext specifically for async void tests. CC @ianhays @Priya91 16979 area-System.Security Add GetDSA(Public|Private)Key methods Fixes #11802.

Alternatively, if it is deemed it SystemColors should not be part of netstandard2.0, I'm not sure it makes much sense to have it in netcoreapp2.0, either. Background: I have ported Mono's System.Drawing to .NET Core and repeating the excercise for netstandard2.0. When compiling Mono's System.Drawing for netstandard2.0, I have to include SystemColors as it is not part of the netstandard2.0 specification. This version can then be consumed on NetFX (given System.Drawing is not referenced) but not on netcoreapp2.0 because you'll get compiler errors trying to distinguish between System.Drawing.SystemColors in netcoreapp2.0 and Mono's System.Drawing. Net, the gist of this issues is to request to have the same API surface for System.Drawing on netcoreapp2.0 and netstandard2.0.

We specifying the path with parameters like this: `CWD ~TNA=AMP,VNA=VOL03,FNA=U-ED-B2-USL` * If you make a listing of files without specifying `FNA`, we get a tree structure with everything on the entire partition. I do not expect that this odd behavior to be implemented in `FtpWebRequest`, but I wish that there is any why to customize `FtpWebRequest `to handle these and other special cases. One way is to have a callback just before commands are sent to the FTP server to provide the ability to customize what is sent and then another callback when the response arrives. Another way might be to make it possible to inherit from `FtpWebRequest `to make your own customized version." 17032 area-Meta NETFramework 4.6 project can not reference project that targets NETStandard 1.4?

These edge cases can mostly be implemented portably. Given that, it would be nice of MemberInfo itself could implement the portable portion, leaving the simplified task for the underlying Reflection provider. This would reduce the amount of implementation underlying Reflection providers have to do and promote more consistent behavior. **Proposal for New API:** `MemberInfo.HasSameMetadataDefinitionAsImpl.` ```c# protected virtual bool HasSameMetadataDefinitionAsImpl(MemberInfo other) { throw new NotImplementedException(); } ``` This would be an extension point for Reflection providers to implement the ""non-portable"" portion of HasSameMetadataDefinitionAs() on non-constructed entities. The specification of `HasSameMetadataDefinitionAsImpl` would be as follows: Return true if and on if this and other... - Have the same MemberType value (i.e. both are methods or both are fields, etc.) - Are implemented by the same Reflection provider. - Represents the same metadata entity (e.g disregarding artifacts such as ReflectedType.) Behavior undefined if: - other is null - this or other is a MethodInfo that represents a constructed generic method (e.g. the result of MethodInfo.MakeGenericMethod() - this or other is a Type that isn't one of - a plain old named type (i.e. HasElementType == false && IsConstructedGenericType == false) - a generic type parameter (i.e. IsGenericParameter == true) The implementation of MemberInfo.HasSameMetadataDefinitionAs() can then be this: ```c# public virtual bool HasSameMetadataDefinitionAs(MemberInfo other) { if (other == null) throw new ArgumentNullException(nameof(other)); MemberInfo thisMember = Distill(this); MemberInfo otherMember = Distill(other); return thisMember.HasSameMetadataDefinitionAsImpl(otherMember); } private MemberInfo Distill(MemberInfo member) { switch (member) { case MethodInfo method: if (method.IsGenericMethod && !method.IsGenericMethodDefinition) method = method.GetGenericMethodDefinition(); return method; case Type type: { while (type.HasElementType) { type = type.GetElementType(); } if (type.IsConstructedGenericType) type = type.GetGenericTypeDefinition(); return type; } default: return member; } } ``` Note that `HasSameMetadataDefinitionAs` is still virtual, allowing providers to replace it entirely if they can provide a more performant version than the default. The default definition, however, still defines the required behavior." 17049 area-System.Net Use vectors in managed ClientWebSocket for mask application The web socket protocol uses a 4-byte mask sent from client to server and xor'd with the payload data. In the managed web socket implementation, that mask is currently applied byte-by-byte. This commit changes it to be done using SIMD. Micro-benchmarks on the ApplyMask function itself show a regression for payload lengths under 4 bytes, but above that it's a clear win: ``` 1: 0.44x 3: 0.64x 4: 1.15x 7: 1.16x 31: 1.73x 32: 6.06x 63: 3.37x 64: 10.40x 1024: 20.36x ``` This doesn't have a measurable affect on small payloads in the overall context of sending/receiving data, but the larger the payload, the more it applies.

"**Proposal for New API:** ```c# class MethodBase { public virtual bool IsConstructedGenericMethod => IsGenericMethod && !IsGenericMethodDefinition; } ``` This is both for completeness (Type has **IsConstructedGenericType**) and for better expressibility when testing if a MethodBase represents a method instantation. Right now, the only way to perform that task is through this eyesore: ```c# if (method.IsGenericMethod && !method.IsGenericMethodDefinition) {...} ``` This is wordy, requires two calls and requires the use of the 1.0-era **IsGenericMethod** (whose very use I consider to be a code smell due to its poor conceptual grasp of the distinction between generic methods and their instantiations.) The proposed implementation allows the new api to give the correct result for 3rd party Reflection providers without any additional work on their part.

This has been fine in the Windows world since it's not used but it *is* used by Unix's `zip`/`unzip` programs to store file permissions of an entry. As it currently stands, there is no way to carry Unix RWX permissions within a zip, so at unzip time the unzipper has to guess at permissions and manually chmod the entries. https://github.com/dotnet/corefx/issues/14853 https://github.com/dotnet/corefx/issues/15516 https://github.com/dotnet/corefx/issues/10223 https://github.com/NuGet/Home/issues/4424 # Solution Permissions isn't an officially supported feature of the [zip specification](https://pkware.cachefly.net/webdocs/APPNOTE/APPNOTE-6.3.3.TXT) but it is used widely enough that we should add support for it. There's a pretty wide range of things we can do here that go from simply exposing the field all the way to implementing [AccessControl for Unix and accepting something from there as input](https://github.com/dotnet/corefx/issues/9225). Since the latter option requires a huge amount of work/new API and marries us to a Zip permissions structure, I suggest we take the simple/future-proof route here and just expose the entire field: ``` public partial class ZipArchiveEntry { public int ExternalAttributes {get; set} } ``` This also has the benefit of potentially supporting other implementations that use the external file attributes field for reasons other than permissions. I'm not aware of any of these off the top of my head, but they ostensibly exist. # Usage The unfortunate aspect of exposing the raw field is that usage becomes a bit more complicated. However, without implementing our own UnixPermissions structure that's somewhat unavoidable. The nice thing is that it leaves us open to implement an explicit UnixPermissions structure in the future (pending the completion of #9225) without conflictions with the ExternalAttributes. [This StackOverflow post does a better job describing the format than I can so I'm just going to link it](http://unix.stackexchange.com/questions/14705/the-zip-formats-external-file-attribute/14727#14727). The permissions values themselves are the same as the ones you get from stat. cc: @stephentoub @JeremyKuhne 17068 area-System.Runtime Proposal: Convenience API for throwing exceptions ## Background It's quite verbose to validate arguments because you have to write an if-statement and `throw new XXXException` for each validation. Even with C# 7's new throw-expressions, you still have to write out the latter part. This makes people write their own helper classes for validating arguments, e.g. [here](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/Validation/Requires.cs) or [here](https://github.com/xunit/xunit/blob/master/src/common/Guard.cs). It would be nice if we had such a helper class as part of the framework. ## Proposal ```cs namespace System { public static class Verify { public static void Argument(bool condition, string message, string argumentName); public static void InRange(bool condition, string argumentName); public static void InRange(string s, int index, int count, string sName, string indexName, string countName); public static void InRange(T[] array, int index, int count, string arrayName, string indexName, string countName); public static void NotEmpty(IEnumerable source, string sourceName); public static void NotNegative(int argument, string argumentName); public static void NotNull(bool condition, string argumentName); public static void NotNull(T argument, string argumentName) where T : class; public static void Positive(int argument, string argumentName); } } // Sample usage: T MyGenericMethod(T[] array, int index, int count) { // Note: All of this is equivalent to Verify.InRange(array, index, count, nameof(array), nameof(index), nameof(count)). // The arguments are validated manually for demo purposes. Verify.NotNull(array, nameof(array)); Verify.NotNegative(index, nameof(index)); Verify.NotNegative(count, nameof(count)); Verify.InRange(array.Length - index >= count, nameof(index)); } ``` A sample implementation [can be found here](https://gist.github.com/jamesqo/13dded2757a8f9f9eb57bbaf944dee1b#file-verify-cs-L79). ## Remarks - In my experience, it's common to validate things like a signed integer being positive/nonnegative, so those patterns will get their own `Positive` / `NotNegative` methods. This will enable us to [provide a better error message](https://gist.github.com/jamesqo/13dded2757a8f9f9eb57bbaf944dee1b#file-verify-cs-L79) if such a check fails. These methods throw the same exception type as `InRange`. - Same applies for `InRange`, `NotEmpty` - The class will work nicely with `using static`: ```cs using static System.Verify; T MyGenericMethod(T[] array, int index, int count) { NotNull(array, nameof(array)); NotNegative(index, nameof(index)); NotNegative(count, nameof(count)); InRange(array.Length - index >= count, nameof(index)); } ``` - The extra `NotNull` overload taking a `bool` covers the rare cases when people are writing generic code, and the parameter might be null but the compiler can't guarantee that it's a class. e.g. [Like here](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/src/System/Collections/Immutable/ImmutableDictionary.cs#L300). It also covers the rare times when someone would want to verify a nullable is non-null. - I didn't include a `NotNull(T?, string) where T : struct` nullable overload since if someone thinks a nullable is non-null they would likely 1) not accept a nullable parameter in the first place, or 2) if they're calling some method they know returns a non-null nullable, they're likely to cast the `T?` to a `T` or call `.Value`, which do the validation automatically, instead of bothering to validate themselves. --- This is a follow-up to https://github.com/dotnet/corefx/issues/12509 after putting some thought into the API. 17069 area-Serialization Added tests for XmlMembersMapping.

For instance, we plan for newer runtimes to support default implementations in interface, and the compiler should be able to detect that you're compiling against an older runtime without that support. Previously, this was done by having the compiler look for APIs that were added coincidentally with the new support. But as we expect to run into this problem more often, it makes sense to have a systematic design for testing feature support. The main consumer of this API would be the compiler. Whenever it needs to check for runtime support, it would look for the corresponding well-known enum member (for instance, `System.Runtime.CompilerServices.RuntimeCapabilities.SupportsDefaultImplementation`). If the member exists, then the feature check is successful (the feature is supported). The value for that enum member is ignored. A number of feature requests or known bugs interfering with compiler or language evolution is documented in https://github.com/dotnet/csharplang/issues/251 # Proposed API (Updated after API review 3/28/2017) (Updated to use ""const"" instead of ""static readonly"" after further discussion 4/13/2017) ```C# namespace System.Runtime.CompilerServices { public static class RuntimeFeature { // Presence of the field indicates runtime support public const string FixedGenericAttributes = nameof(FixedGenericAttributes); public const string DefaultImplementation = nameof(DefaultImplementation); // Runtime check public static bool IsSupported(string feature); } } // Usage if (RuntimeFeature.IsSupported(""SomeNewerFeature"") { // Use feature when emitting code at runtime (CodeDOM, RefEmit etc) } ``` * **Static detection**. The presence of a field alone indicates whether the code compiled against it can rely on the runtime providing the feature. This allows us to model runtime capabilities like any other API, which includes leveraging our existing infrastructure for detecting breaking changes. Also, this allows us to express this in .NET Standard and will version like any other API. * **Runtime detection**. There are some (very limited) scenarios where someone might want to do feature detection at runtime, in particular runtime code generation using RefEmit. We don't expect many developers to call this API. Usage of this API will always involve a literal, as having a field in scope would imply `IsSupported` must return `true`. Developers using light-up would discover the strings by looking at the documentation of a particular .NET platform. # Original proposed API (rejected in favor of the one above) ```C# namespace System.Runtime.CompilerServices { public enum RuntimeFeatures { FixedGenericAttributes, SupportsDefaultImplementation, // ... this list would grow over time } } ``` # Maintenance process Adding new enum members would go through the standard API review process. The main requirement is that enum names should mean the same thing across the different runtimes (desktop, core, RT, mono). Also, there needs to be documented agreement between the runtimes and compilers about the meaning of each new member.

See https://linux.die.net/man/5/tzfile. The transition times of each time zone are stored in this file. Every time the offset from UTC changes, an entry is made.

So from Nov 17 to Feb 25 every year, the time zone should not be in daylight savings time, which is incorrect because the time zone was in DST all year round those 5 years. I don't think we should be populating these Daylight TransitionTime values at all when giving the AdjustmentRules to public consumers. Anyone who wants to consume this information is going to be broken trying to use it. This is just going to lead to incorrect information being displayed to their users. ### Code to print the above table ``` class Program { static void Main(string[] args) { TimeZoneInfo tz = TimeZoneInfo.FindSystemTimeZoneById(""Africa/Casablanca""); System.Console.WriteLine($""Baseoffset: {tz.BaseUtcOffset}""); StringBuilder builder = new StringBuilder(); builder.Append(""DateStart""); builder.Append(""\t""); builder.Append(""DateEnd""); builder.Append(""\t""); builder.Append(""\t""); builder.Append(""DaylightDelta""); builder.Append(""\t""); builder.Append(""DaylightTransitionStart""); builder.Append(""\t""); builder.Append(""DaylightTransitionEnd""); System.Console.WriteLine(builder); var rules = tz.GetAdjustmentRules(); DateTime startDate = new DateTime(1945, 12, 31); //DateTime startDate = DateTime.Now; foreach (var rule in rules.Where(r => r.DateStart < startDate).Reverse().Take(5)) { builder = new StringBuilder(); builder.Append(rule.DateStart.ToString(""MM/dd/yyyy"")); builder.Append(""\t""); builder.Append(rule.DateEnd.ToString(""MM/dd/yyyy"")); builder.Append(""\t""); builder.Append(rule.DaylightDelta); builder.Append(""\t""); PrintTransition(rule.DaylightTransitionStart, builder); builder.Append(""\t""); PrintTransition(rule.DaylightTransitionEnd, builder); System.Console.WriteLine(builder); } } private static void PrintTransition(TimeZoneInfo.TransitionTime transition, StringBuilder builder) { builder.Append($""M{transition.Month}.w{transition.Week}.d{transition.Day} {transition.TimeOfDay.ToShortTimeString()}""); } } ``` /cc @tarekgh @mj1856 " 17121 area-System.Net Rewrite System.Net.Security's FixedSizeReader.AsyncReadPacket as an async method Rewrite the FixedSizeReader.AsyncReadPacket as an async void method. It's still allocation-free if the delegated ReadAsync completes synchronously, but if it completes asynchronously, there's now less allocation (fewer and smaller objects); there's slightly less if a single read is required, but those same allocations are then reused across all reads, so if multiple reads are needed, there's a significant decrease. And the code is easier to read. Also changes FixedSizeReader to be a static class, avoiding several being allocations per SslStream. cc: @geoffkizer, @cipop, @davidsh, @Priya91 17122 area-Infrastructure Enable multi queue for Linux /cc @MattGal 17125 area-System.Threading Add Thread.CurrentPrincipal, Thread.GetDomain, and Thread.GetDomainID for uapaot. 17126 area-System.Data SqlClient implementation and API is not complete in Core The following members are on types implemented in .NET Core. However these particular members are missing, although they are present on Desktop. The problem with this situation is - it defies user expectations that if a type X exists, code from other platforms that use X will work on .NET Core - it cannot be fixed without servicing -- it is not possible to supply a standalone package with the rest of the type definition No work is necessarily required here for 2.0. It's not part of NS2.0. I didn't look at usage data. I'm just flagging this so we're doing this consciously. --- **Updated lists to reflect current status (5/15):** ### Missing APIs ``` T:System.Data.SqlClient.OnChangeEventHandler

Ensure consistent usage of Roslyn compilers Right now we have a custom targets and task that allows us to pass in the host process via OverrideToolHost (https://github.com/dotnet/corefx/blob/977f6e021235b8ff5bab8baf4bf53d03af4706f8/Tools-Override/Build.Common.props#L40) which is inconsistent with the shipping task library. This causes some issues like https://github.com/dotnet/coreclr/issues/10056 and also requires us to maintain a private fork which isn't ideal. That hack was a workaround for https://github.com/Microsoft/msbuild/issues/720 (replaced with https://github.com/Microsoft/msbuild/issues/1669) but we should work around this in a different way. Mostly likely similar to how CLI did it with a wrapper script https://github.com/dotnet/cli/blob/rel/1.0.0/src/dotnet/commands/dotnet-msbuild/MSBuildForwardingApp.cs#L109-L113. On top of cleaning up this we should remove a lot of our dead properties like UseRoslynCompiler (https://github.com/dotnet/corefx/blob/977f6e021235b8ff5bab8baf4bf53d03af4706f8/Tools-Override/Build.Common.props#L44) and move UseSharedCompilation (https://github.com/dotnet/corefx/blob/977f6e021235b8ff5bab8baf4bf53d03af4706f8/Tools-Override/Build.Common.props#L45) into https://github.com/dotnet/corefx/blob/0eb6859a29501722475dfec484f80c43de0c70e0/Tools-Override/Roslyn.Common.props. We should also start using CSharpCoreTargetsPath like Rolsyn itself does (https://github.com/dotnet/roslyn/blob/master/build/Targets/Settings.props#L121), instead of computing the RoslynPropsFile directly and importing it at (https://github.com/dotnet/corefx/blob/b1865ea0847a7a86baefe8378b772ecf0b785681/dir.props#L278) . This should better set us up to consume the custom compiler without a bunch of customizations we have today. cc @chcosta @joperezr 17132 area-System.Diagnostics Fix secannotate errors introduced by #17076 in DiagnosticSource "On the target that do not declare AllowPartiallyTrustedCallers (all except net46 and netfx), secannotate shows a critical error ```c# 'System.Diagnostics.Activity.GetRandomNumber()', a security critical member, is marked with a safe-critical annotation.

Examples include: * SDL2 * OpenAL * Vulkan * Many more (the above are just ones I've used personally) CoreCLR does not support any notion of ""remappable"" PInvokes, a la DllImport in Mono. The name of the shared library must be encoded directly in the `DllImport` attribute, which makes it impossible to create a single wrapper assembly which works on many platforms. This imposes an unnecessary development and deployment burden on library developers who could otherwise ship a single, simple DLL. Many third-party libraries which rely on PInvoke's only work on Mono platforms because of the DllMap feature. These libraries do not work on .NET Core at all, even if they are otherwise completely compatible with its profile. The alternative to using `[DllImport]` is to write logic which manually opens the shared library, discovers function pointers, and converts them to managed delegates. In a sense, this very similar to what we are doing with our ""Portable Linux"" version of the runtime and native shims. However, this code can be complicated, tedious, and error-prone. This proposal is for a small helper library, with optional cooperation by the runtime, to make this scenarion easier. ## Proposed API ```C# namespace System.Runtime.InteropServices { // Exposes functionality for loading native shared libraries and function pointers. public class NativeLibrary : IDisposable { // The default search paths public static IEnumerable NativeLibrarySearchDirectories { get; } // The operating system handle of the loaded library. public IntPtr Handle { get; } // Constructs a new NativeLibrary using the platform's default library loader. public NativeLibrary(string name); public NativeLibrary(string name, DllImportSearchPath paths); public static NativeLibrary Open(string name, DllImportSearchPath paths, bool throwOnError); // Loads a native function pointer by name. public IntPtr LoadFunction(string name); // Loads a function whose signature matches the given delegate type's signature. // This is roughly equivalent to calling LoadFunction + Marshal.GetDelegateForFunctionPointer public T LoadDelegate(string name); // Lookup a symbol (not a function) from the specified dynamic library public IntPtr SymbolAddress(string name); // Frees the native library. Function pointers retrieved from this library will be void. public void Dispose(); } } ``` ## Usage ```C# public static class Sdl2 { private static NativeLibrary s_sdl2NativeLib = new NativeLibrary(GetSdl2LibraryName()); // Determine library name at runtime. This could be influenced by a DllMap-like policy if desired. private static string GetSdl2LibraryName(); private delegate IntPtr SDL_CreateWindow_d(string title, int x, int y, int w, int h, int flags); private static SDL_CreateWindow_d SDL_CreateWindow_ptr = s_sdl2NativeLib.LoadFunctionPointer(""SDL_CreateWindow""); public static IntPtr CreateWindow(string title, int x, int y, int w, int h, uint flags) => SDL_CreateWindow_ptr(title, x, y, w, h, flags); } public static void Main() { IntPtr window = Sdl2.CreateWindow(""WindowTitle"", 100, 100, 960, 540, 0); } ``` ## Open Design Questions ### Probing Path Logic CoreCLR applies particular probing logic when discovering shared libraries listed in a `DllImport`. Ideally, calling `new NativeLibrary(""lib"")` would follow the same probing logic as `[DllImport(""lib"")], so that PInvoke's can be easily converted. This could potentially be solved with some internal or public runtime helper function exposed from System.Private.CoreLib. Alternatively, the constructor for `NativeLibrary` could include another parameter which controlled probing logic, allowing someone to plug their own logic in. ### Generic delegate types The simplest way to convert from a native function pointer to a clean managed delegate is through the use of `Marshal.GetDelegateForFunctionPointer(IntPtr)`. Unfortunately, this cannot be used with generic delegates, e.g. `Func` in the above example. Given that many native function signatures include pointer types, which cannot be used as generic type arguments, other than as `IntPtr`, this is not a major problem. However, many cases would benefit from being able to use `Action` and `Func` types in the `LoadFunction` method. We could probably allow this using Reflection.Emit, but it would most likely be ugly, complicated, and slower than if custom delegate types were used. If `Marshal.GetDelegateForFunctionPointer(IntPtr)` accepted generic delegate types, this feature would greatly benefit. ### Disposability and lifetime tracking The constructor of `NativeLibrary` involves opening an operating system handle to a native shared library, via `LoadLibrary`, `dlopen`, etc. I have proposed that `NativeLibrary` be disposable, which would involve calling `FreeLibrary`, `dlclose`, etc. Is this desirable or useful? A related issue is how the runtime currently tracks and manages these handles. Should handles opened by `NativeLibrary` be coordinated and tracked in the same way that other handles (via PInvoke, etc.) are? ## Prototype I have a prototype version of this library implemented here: https://github.com/mellinoe/nativelibraryloader, and I have successfully used the pattern described here in a few projects. @yizhang82 @janvorli @danmosemsft @conniey " 17136 area-Meta When method is not impl, we should not throw NotSupportedException() We standardized on throwing PlatformNotSupportedException() even if we don't support the API on _any_ platform.

NetworkStream.WriteAsync then just delegates to SendAsync. But WriteAsync returns a non-generic task, and doesn't actually care or surface the result value, which means we can effectively use any task, regardless of its value, and can thus use a single cached task for all synchronous completions, regardless of how much data is written. With this change, then, the common-case of synchronously completing NetworkStream.WriteAsync calls don't allocate (amortized). cc: @geoffkizer, @cipop, @Priya91 17187 area-System.Diagnostics TestCommonPriorityAndTimeProperties failed in CI on macOS https://ci.dot.net/job/dotnet_corefx/job/master/job/osx10.12_debug_prtest/123/consoleText ``` System.Diagnostics.Tests.ProcessThreadTests.TestCommonPriorityAndTimeProperties [FAIL] Assert.True() Failure Expected: True Actual: False Stack Trace: /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Diagnostics.Process/tests/ProcessThreadTests.cs(26,0): at System.Diagnostics.Tests.ProcessThreadTests.TestCommonPriorityAndTimeProperties() ``` 17188 area-System.Net Socket.Begin/EndSendFile completing asynchronously hangs on macOS 17189 area-System.Net Fix Socket.Disconnect on Unix 17190 area-System.Xml System.Xml.XPath.XmlDocument is no longer getting produced/published `System.Xml.XPath.XmlDocument` is not in the shared framework, and there are no recent nuget packages for it on https://dotnet.myget.org/feed/dotnet-core/package/nuget/System.Xml.XPath.XmlDocument.

But for IPv4 and IPv6, the two most common families, we know the address size in advance, and can simply use those values rather than allocating to get them. If in the future other families become more common, we could cache those dynamically after computing them once. cc: @geoffkizer, @pgavlin, @KrzysztofCwalina, @cipop, @davidsh 17201 area-Meta Replaced ContainsKey() Calls with TryAdd() Dictionary Calls Replaced usage of the `Dictionary.ContainsKey()` method with the newer `Dictionary.TryAdd()` method (where applicable) for performance benefits [per Issue #17034](https://github.com/dotnet/corefx/issues/17034).

This is a question more than an issue which will help with the design of Azure Active Directory authentication for Azure SQL DB. SqlClient on Desktop depends on a DLL written in C++ and utilizes Windows APIs which needs to be installed on the client machine to be able to authenticate to Azure SQL DB using AAD. For .Net Core, the solution provided above doesn't apply as it is not applicable to Unix or macOS. To add Azure Active Directory support in SqlClient, the access token has to be retrieved from AAD using HTTP rest calls. There are client libraries provided by AAD in C# to expedite clients to retrieve the Access Token. Can SqlClient take a dependency on one of these libraries? If we cannot take a dependency, then SqlClient needs to implement the Access Token retrieval in the client itself which is a big maintenance overhead. What is the guidance in this case? Was such a design decision needed by any other .Net Core libraries? 17204 area-System.Drawing Add missing [Browsable(false)] attributes to Drawing primitives These attributes are present on Desktop .NET but are missing from .NET Core.

But we can approximate it in the .NET layer on Unix, e.g. by accepting into a new socket and transferring over the SafeCloseHandle and related state. This will allow the same APIs to be used cross-platform so that code running on Windows gets the intended benefits while not having to fork based on the OS. 17210 area-System.Net Add test for accepting into a disconnected socket We already have a test that accepts into an existing socket, but not one that tests reusing that same socket for another accept.

System.Net.Security 4.3.0 breaks, at the very least, authenticating with Apple's push notification servers in an unusual way -- but only on Linux. It still works fine when used on Windows. Here is a simple C# program, which does the bare minimum I've found to trigger this bug. For obvious reasons, I cannot provide the certificate file, although I expect any other instances of certificate client authentication would likely also trigger the bug. ```c# using System; using System.IO; using System.Net; using System.Net.Sockets; using System.Net.Security; using System.Security.Cryptography.X509Certificates; using System.Security.Authentication; using System.Threading.Tasks; namespace Test { class Program { static void Main() { Task.Run(async () => { int port = 2195; string hostname = ""gateway.push.apple.com""; X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(""certificate.pfx"")); X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate); TcpClient client = new TcpClient(AddressFamily.InterNetwork); await client.ConnectAsync(hostname, port); SslStream sslStream = new SslStream(client.GetStream()); await sslStream.AuthenticateAsClientAsync(hostname, certificatesCollection, SslProtocols.Tls12, false); Console.WriteLine(""Success.""); }).Wait(); } } } ``` And here is a matching csproj file: ```xml Exe netcoreapp1.0 * * 4.0.0 * * ``` When System.Net.Security depends on 4.0.0, the program works as expected; it successfully authenticates, prints ""Success!"", then exits. If you change that dependency to 4.3.0, it instead pauses, then exits the program with no console output during AuthenticateAsClientAsync, and never prints ""Success!"". No exceptions are thrown, it just seemingly cleanly exits, when it should not." 17219 area-System.Runtime Add APTC attribute to System.ValueTuple.dll in .Net Standard 1.0 The attribute is not added in the `portable_net40+sl4+win8+wp8` target group, as it doesn't seem to exist there. Let me know if that can be improved somehow. In target group `netcoreapp`, the assembly that has type forwards doesn't have the attribute and neither does `System.Runtime` (which type forwards further), but the implementation assembly (`System.Private.CoreLib.dll`) does have APTCA. So the `netstandard1.0` target group is the only one benefiting from this fix.

There is, however, no robust way to know if a type has these restrictions. Apis like Array.CreateInstance() need to guard against these types (https://github.com/dotnet/corert/pull/3000) and could use a formalized way to catch these types.

However, the functions for performing Unicode case mapping (culture-insensitive uppercase and lowercase) appear to reflect Unicode version 1.0. This mismatch was a severe impediment for implementing spec-compliant case folding in the VB compiler. There is also no support whatsoever for performing case folding according to the Unicode specification (simplified or otherwise). APIs in the platform to do this would help with any language that, like VB, wants to depend on the Unicode specification for the meaning of case-insensitive identifiers. --- @jkotas commented on [Mon May 11 2015](https://github.com/dotnet/coreclr/issues/976#issuecomment-101117346) cc @ellismg --- @ellismg commented on [Mon May 11 2015](https://github.com/dotnet/coreclr/issues/976#issuecomment-101125393) This is something I'd like to do. I think the open issue is how we support this on Windows (since I think that we can get Case Folding functionality from ICU). In general, we've tried to move away from the framework itself shipping globalization data and used the OS provided APIs instead. Since Windows doesn't currently expose a way to do case folding, we'd have to figure out what to do. --- @karelz commented on [Fri Mar 17 2017](https://github.com/dotnet/coreclr/issues/976#issuecomment-287305272) @tarekgh do we need a new API for this?

I believe this issue might have started after migrating to csproj from project.json. 17273 area-Meta Generic Type Check Inlining "When writing performance-critical code it often leads to code duplication. Let's say we wanted to make a method that applies an effect on an image, in our case we want to apply a gray-scale and an optional invert. The code could look like this: ```C# public class Effect { public static void Apply(Bitmap bmp, GreyscaleMethod grayscaleMethod, bool invert) { // read bitmap data int w = bmp.Width, h = bmp.Height; var data = bmp.LockBits(new Rectangle(0, 0, w, h), ImageLockMode.ReadWrite, bmp.PixelFormat); if (bmp.PixelFormat != PixelFormat.Format32bppArgb) throw new InvalidOperationException($""Unsupported pixel format: {bmp.PixelFormat}""); var s = data.Stride; unsafe { var ptr = (byte*)data.Scan0; for (int y = 0; y < h; y++) { for (int x = 0; x < w; x++) { // read RGB (not quite optimized, but that's not the point) int offset = y * s + x; int r = ptr[offset + 1]; int g = ptr[offset + 2]; int b = ptr[offset + 3]; // apply effects per pixel if (grayscaleMethod == GreyscaleMethod.Average) { r = g = b = (r + g + b) / 3; } else if (grayscaleMethod == GreyscaleMethod.Luminance) { r = g = b = (int)(r * 0.2126 + g * 0.7152 + b * 0722); } if (invert) { r = 255 - r; g = 255 - g; b = 255 - b; } // write RGB ptr[offset + 1] = (byte)r; ptr[offset + 2] = (byte)g; ptr[offset + 3] = (byte)b; } } } bmp.UnlockBits(data); } } public enum GreyscaleMethod { None, Average, Luminance, } ``` However if we expect the invert to be only rarely used, that code is slower than it can be because of the constant `if (invert)` check inside the performance-critical inner loop. We could of course create another method that gets called when `invert` is false, but that leads to code duplication, is harder to maintain, etc. What we would need to have both optimal performance and code reuse is a way to get the compiler to generate 2 methods at compile time depending on the value of `invert`. Without any new syntax the code might look like this: ```C# public class Effect { private static void Apply(Bitmap bmp, GreyscaleMethod grayscaleMethod) where invert : Bool { // [...] read bitmap data unsafe { var ptr = (byte*)data.Scan0; for (int y = 0; y < h; y++) { for (int x = 0; x < w; x++) { // [...] read RGB // apply effects per pixel if (grayscaleMethod == GreyscaleMethod.Average) { r = g = b = (r + g + b) / 3; } else if (grayscaleMethod == GreyscaleMethod.Luminance) { r = g = b = (int)(r * 0.2126 + g * 0.7152 + b * 0722); } if (typeof(invert) == typeof(True)) { // type check r = 255 - r; g = 255 - g; b = 255 - b; } // [...] write RGB } } } bmp.UnlockBits(data); } } public class False : Bool { } public class True : Bool { } public class Bool { } ``` Now that check if a compile-time constant, so the compiler *could* remove the type-condition and its block away when `invert` is `False`, and remove the type-condition but leave its block when `True`, leading to performance optimal code in both cases without code duplication. However does the compiler (or even the JIT) do that? According to [this stackoverflow answer](http://stackoverflow.com/questions/34306049/will-this-comparison-be-compiled-into-a-constant-boolean-value-in-a-generic-clas) it currently does not. This is a proposal to improve the compiler (or JIT) to do that sort of code inlining (through method duplication) for compile-time constant checks. If this were implemented, we can optimize the code even further by doing the same with the `grayscaleMethod` parameter: ```C# public class Effect { private static void Apply(Bitmap bmp) where invert : Bool where greyscaleMethod : GreyscaleMethodEnum { // [...] read bitmap data unsafe { var ptr = (byte*)data.Scan0; for (int y = 0; y < h; y++) { for (int x = 0; x < w; x++) { // [...] read RGB // apply effects per pixel if (typeof(greyscaleMethod) == typeof(GreyscaleMethod_Average)) { r = g = b = (r + g + b) / 3; } else if (typeof(greyscaleMethod) == typeof(GreyscaleMethod_Luminance)) { r = g = b = (int)(r * 0.2126 + g * 0.7152 + b * 0722); } if (typeof(invert) == typeof(True)) { r = 255 - r; g = 255 - g; b = 255 - b; } // [...] write RGB } } } bmp.UnlockBits(data); } } public class GreyscaleMethod_None : GreyscaleMethodEnum { } public class GreyscaleMethod_Average : GreyscaleMethodEnum { } public class GreyscaleMethod_Luminance : GreyscaleMethodEnum { } public class GreyscaleMethodEnum { } ``` Doing the same optimization through code duplication would require 6 methods, and the number would increase exponentially with the number of parameters. However the compiler would know to only generate the methods which are actually used in the code. " 17275 area-System.Collections Migrate new convenience APIs into extension methods Highly used generic types (mostly Collections) pay high cost for every API (method) we add to it. We should revisit the decisions of adding new APIs (esp. convenience APIs) directly on the type and consider moving them into extension methods instead (in future and potentially revisit those we added during 2.0 and did not publish yet).

However, they do not provide a way to ensure that items are not added more than once at a given time. For instance, if you are using an `ActionBlock` to process files received, there is no mechanism to ensure that the file is not added a second time if it is already present (e.g. via a manual catchup process). class Program { private static readonly ActionBlock worker = new ActionBlock(file => ProcessFile(file), new ExecutionDataflowBlockOptions() { MaxDegreeOfParallelism = 1 }); private static void ProcessFile(string file) { //Process the File. new ManualResetEvent(false).WaitOne(10000); File.Delete(file); } private static Timer ScanTimer; static void Main(string[] args) { ScanTimer = new Timer() { Interval = 1000, AutoReset = true, Enabled = true }; ScanTimer.Elapsed += (sender, eventArgs) => GetFiles(); ScanTimer.Start(); } private static void GetFiles() { foreach (var file in Directory.EnumerateFiles(@""C:\Temp\Files"", ""*.*"", SearchOption.TopDirectoryOnly)) { worker.Post(file); //Files currently Queued will be added a second time. } } } Can we add a mechanism to ensure uniqueness? Some options: * Expose methods to show InProcess/QueuedItems. Allow users to implement their own checking. e.g. `worker.PostedItems` * Provide an, `ExecutionDataflowBlockOptions` Property to ensure uniqueness. Options on this: * Uniqueness using the default `Equals` mechanism - Devs are required to override this if required for specific use cases. * Allow devs to specify an equality method during specification of the option, e.g. ` new ExecutionDataflowBlockOptions() { EnsureUniqueness = (a, b) => return a.Id == b.Id }`" 17295 area-System.Net Remove SocketAsyncEventArgs._ptrNativeOverlapped `SocketAsyncEventArgs` uses a `SafeNativeOverlapped` to represent the `NativeOverlapped*` it gets back from the `PreAllocatedOverlapped`. This leads to several costs: - Allocation/disposal of the `SafeNativeOverlapped`. It used to be allocated/disposed for every operation, and that was fixed. But it's still allocated/disposed every time the `SocketAsyncEventArgs` changes associated with a `Socket`, and that's problematic in a pooling situation, where a `SocketAsyncEventArgs` is taken from a pool, used for an operation, and then returned to the pool to be used subsequently by another operation, likely on a different socket. - It adds a field to `SocketAsyncEventArgs`, as the `SafeNativeOverlapped` instance needs to be disposed of only when the operation completes. - As with any `SafeHandle`, it adds AddRef/Release costs to each P/Invoke with which it's used. But, it's unnecessary on `SocketAsyncEventArgs`. The overlapped has a very controlled lifetime: it's created internally, it's passed to an internal async operation, and upon completion of that operation it's freed. The benefits of the `SafeHandle` don't apply here: - `SafeHandle`s help guaranteed cleanup via a finalizer, but we're not publishing this pointer and have knowledge of its complete lifetime. The only place it would help is if we got an asynchronous exception (e.g. a thread abort) in a very unexpected place, and we don't need to be reliable against such things (nor would we be even if we added that). - `SafeHandle`s help guarantee that the pointer won't be disposed of while still in use, but that's mainly relevant when handed out to multiple pieces of code, and in particular code we don't control... in this case, it's not handed out to any code other than that in this one file. On my machine, this improves the throughput by ~13% in the example at https://github.com/dotnet/corefx/pull/17237#issuecomment-287613725 (which is stressing this case by changing the socket on every send/receive and doing very fast send/receives), and makes it allocation-free to change the Socket with which a SocketAsyncEventArgs is associated (whereas today there’s a 40byte SafeHandle allocation each time it changes). With a small modification to that test to not change the buffer and instead set it once up front, this still has an ~8% throughput improvement, most of which is due to the reduction in SafeHandle marshaling and associated AddRef/Release costs. cc: @geoffkizer, @davidsh, @cipop, @jkotas, @vancem 17296 area-System.Net Renames the HTTP outgoing request Activity to HttpReqOut It was named simply 'Activity' which is too generic.

There's also CopyFile2 (or CopyFileEx), which support cancellation and progress. That API should enable exposing additional overloads of File.Copy: * `(..., CancellationToken cancellationToken);` * `(..., IProgress progress);` * `(..., IProgress progress, ICancellationToken cancellationToken);` With something like: ```c# public class CopyFileProgressInfo { public long TotalFileSize { get; } public long TotalBytesTransferred { get; } // Remaining values are less important. public long StreamSize { get; } public long StreamBytesTransferred { get; } public int StreamNumber { get; } public string SourceFileName { get; } public string DestinationFileName { get; } // Or even more values could be added; details depends on which API is used. } ``` for progress. Current alternatives, such as using CopyToAsync from one stream to another, can't take advantage of a number of optimizations done within the CopyFile* APIs, including avoiding network roundtripping of the data when copying from a server to a server. Some additional details: https://blogs.technet.microsoft.com/markrussinovich/2008/02/04/inside-vista-sp1-file-copy-improvements/ In practice, I've seen CopyToAsync on streams be multiple times slower than File.Copy (CopyFile* APIs).

As mentioned in the related issue, .NET alternatives lose significant performance optimizations done within the CopyFile* APIs. It would be great if .NET had a good, general purpose, async file copy method. Doing so well (fast) probably requires a new Win32 API that support something like overlapped I/O to avoid blocking the calling thread. Some possible overloads: * `Task CopyAsync(string sourceFileName, string destFileName);` * `Task CopyAsync(string sourceFileName, string destFileName, CancellationToken cancellationToken);` * `Task CopyAsync(string sourceFileName, string destFileName, IProgress progress, CancellationToken cancellationToken);` It probably makes sense to provide an async version of File.Move at the same time, which also likely requires new Win32 API support. 17309 area-System.Reflection Recognize the framework and version of an assembly with the MetadataReader The System.Reflection.Metadata.MetadataReader class allows me to read the metadata without loading permanently the assembly in memory. Once I open the assembly with the MetadataReader, what is the best way to distinguish the assemblies targeting different frameworks? - netstandard (framework neutral) - .net framework - .net core And for each of those, how can I read the version (I mean for example netstandard1.4, netcoreapp1.1 and net 4.6.2)? Reading the custom attributes or what else? 17316 area-Meta General performance question (comparing Nightly to 1.1) I've got a console app and library I'm working on that targets CoreFx 1.1 and 2.vNext (the nightly). I also target the full framework. This app (which will be released as OSS soon) parses text documents and spits out new text documents. It hits the System.IO APIs (mostly Path.GetFullPath), System.Text APIs (mostly StringBuilder), the collection classes (mostly Dictionary<,>), and System.Text.RegularExpression API (mostly matching). The CoreFx 1.1 build (compiled in release mind you) runs about 25% slower than the full framework build (4.6.2) of the app. The CoreFx 2.0 nightly build (also in compiled in release) runs about 40% slower than full framework and 15% slower than CoreFx 1.1 version of the app (for the code compiled against my local copy of the nightly, I did a release publish build just to be sure that I was running against the latest DLLs). Are there any ingrained debug flags, etc., that need to be disabled (perhaps by command line option?) when compiling the latest CoreFx sources to get maximum performance? Or is there some other general reason that might explain the performance drop I'm seeing from 1.1? This is the same exact code running on all three platforms. I will be publishing this project soon. So it might be worth looking into at that point. I don't know if the profiling tools are working for the latest CoreFx builds yet. If so, I'd be happy to post profiler results if anyone can point me to some documentation on how to profile when dogfooding a local build of CoreFx. I'm sure the focus right now is more on completeness and correctness. But I am a bit of a performance hawk. So I thought I'd ask. 17317 area-System.Net WinRT WebSocket throws unhandled exception on lost connection "The issues affects UWP implementation of `ClientWebSocket`.

These directly // correspond to the high two bytes of the Unix `zip` external attributes encoding. entry.ExternalAttributes |= (output.Mode << 16); } } ``` ``` // ZipFileExtensions.Windows.cs public static partial class ZipFileExtensions { internal static ZipArchiveEntry DoCreateEntryFromFile(ZipArchive destination, string sourceFileName, string entryName, CompressionLevel? compressionLevel) { return SharedDoCreateEntryFromFile(destination, sourceFileName, entryName, compressionLevel); } } ``` ``` // ZipFileExtensions.cs public static partial class ZipFileExtensions { internal static ZipArchiveEntry SharedDoCreateEntryFromFile(ZipArchive destination, string sourceFileName, string entryName, CompressionLevel? compressionLevel) { .... this is the same code as the current DoCreateEntryFromFile } } ``` # Usage There's a question here as to whether the permissions capturing/writing should be done by default or whether we should offer an opt-in/opt-out. There's very little cost associated with including permissions in the zips that we create and not any compat worries, but applying permissions to unzipping is a bit more tricky. # Benefit Zips created using ZipFile on Unix will be usable interchangeably with those created using the `zip` command as far as permissions are concerned. Using ZipFile to unzip zips created with `zip` will create files that have the same permissions as they were created with. @eerhardt is happy. cc: @stephentoub @JeremyKuhne @terrajobst 17345 area-System.Reflection "Need an api to determine if a Type is a ""plain old non-constructed type.""" "**Proposal for New API:** ```c# class Type { public virtual bool IsTypeDefinition { get { throw NotImplemented.ByDesign; } } } ``` **Why** Right now, if we want to test if a type is a plain old non-constructed type (i.e. ""one with a mdTypeDef metadata token""), we have to use this windy expression: ```c# if (!type.HasElementType && !type.IsConstructedGenericType && !type.IsGenericParameter) {...} ``` There are a few problems with this: - It's a mouthful. - It take 3 virtual calls - It's not robust against future expansions of the api. Suppose a future expansion to Reflection adds more slices to the Venn diagram (e.g. function pointer types, modified types, or something not yet envisioned...). We want to be able to write robust code that falls through to an ""I don't understand this. NotSupportedException"" fallback, but right now, there's no way to do that. We have to call every other **Is** property we know of, then hope that the ""else"" case will represent the right set for all time. There is also completeness issue - we have inclusion predicates for every other slice of the Venn diagram, yet the most common slice of all lacks one? **Naming** I'm proposing it be called **IsTypeDefinition** for two reasons: - We already have **IsGenericTypeDefinition** that captures the subset of defined types with generic parameters. So **IsTypeDefinition** is a natural derivation from that. - It also rhymes naturally with **Assembly.DefinedTypes** (which returns all the non-constructed types in an assembly.)" 17346 area-Infrastructure Run package closure validation during official builds, possibly CI I added some validation for packages in https://github.com/dotnet/corefx/pull/17246 This is tracking additional improvements: - [x] Switch to latest CLI and MSBuild based projects. - [ ] Add test cases post-restore that examine the following: - [x] No bin-clashes - [ ] API compat between ref & lib. - [x] No type-clashes in ref. - [x] Verify closure - [ ] Enable the tests to run in helix / official builds.

These methods are listed in section 9.1 of the [IEEE 754 spec](https://www.csee.umbc.edu/~tsimo1/CMSC455/IEEE-754-2008.pdf) as recommended functions. The methods return sin(pi * x) and cos(pi * x). They are different from Sin(PI * x) and Cos(PI * x) because PI is a finite-precision approximation to pi, while pi in the definition of SinPi and CosPi is effectively infinitely precise. The limited precision of PI can cause unexpected behavior for functions like Sin(PI * x). For example, while sin(pi * n) = 0 for all integer n, Sin(PI * n) != 0.0 for any n != 0, and can get quite far from zero for large n. (See issue #10276). SinPi(n) == 0.0 for all n. It is actually easier to implement SinPi and CosPi than Sin and Cos. Internally, Sin and Cos are computed in two steps: first x is written as x = m (pi / 2) + x', where m is an integer and |x'| <= pi / 4, then sin(x') is determined via an optimized expression that only applies to the allowed range of x'. The first step is actually quite difficult, since one requires an extended-precision value of pi (~1100 bits) and corresponding a extended-precision multiplication algorithm in order to determine x' within a few ulp for all representable x. For SinPi and CosPi, the ""range reduction"" step is a simple round-to-nearest-integer in order to write 2 x = m + x'. The resulting fractional part is then fed into the same small-angle logic used in Sin and Cos after range reduction. Ideally, this would be implemented inside the same native library that computes Sin and Cos, so that one could route directly to the small-angle logic after the round-to-nearest-integer logic. But I am told that this native library does not expose its internal small-angle method, nor does it implement SinPi and CosPi. Even implemented in managed code, though, SinPi and CosPi should be quite fast, because round-to-nearest-integer is fast and most of the range reduction machinery inside Sin and Cos will be bypassed for small arguments. Here is a simple example implementation: ``` public static double SinPi (double x) { if (x < 0.0) return (-SinPi(-x)); long y0; double y1; ReduceByOnes(2.0 * x, out y0, out y1); double z = Math.PI / 2.0 * y1; // Since |y1| <= 0.5, PI is a sufficiently good approximation to pi to preserve full accuracy // in this product and the following trig function. switch (y0 % 4L) { case 0L: return Math.Sin(z); case 1L: return Math.Cos(z); case 2L: return -Math.Sin(z); case 3L: return -Math.Cos(z); default: throw new InvalidOperationException(); } } private static void ReduceByOnes(double x, out long x0, out double x1) { double y = Math.Round(x); const double max = (double) (1L << 56 ); if (y < max) { // All integers can be represented with full precision by a double fit into a long. x0 = (long) y; x1 = x - y; } else { // For sufficiently big values, all representable doubles are integers divisible by 4. x0 = 0L; x1 = 0.0; } } ``` The spec also recommends AtanPi and Atan2Pi, and TanPi is another natural candidate." 17354 area-Infrastructure Readd testResults.xml now that FileStream is available for uapaot cc: @weshaggard Now that FileStream is available in uapaot we can re-add the xunit option to write testResults.xml plus also add the option to redirect the output of the Console to a file and then printing the contents of that file. 17356 area-System.Text System.Text.Encoding.GetEncoding(Int32 codepage) 850 error "While migrating SharpZipLib pcl library to netstandard1.3 and tests to netcore2.0 I noticed an issue with a few of their tests: ``` ``` This is what triggers the exception: `System.Text.Encoding.GetEncoding(defaultCodePage);` Default code page gets set like that: `static int defaultCodePage = Encoding.UTF8.CodePage;` Did we change anything with netcore regarding codesets?

I've tried adding a reference to every single System.Runtime.* NuGet package and I've tried targeting every single version of .NET Standard and .NET Core App 1.1 to no avail. Is this API available in .NET Core, and if so, what do I need to do to use it? Thanks. 17378 area-System.Memory IPAddress: use Span to support less allocaty IPv6 The IPAddress class has a constructor which accepts a long and an Address property that returns a long: ```c# IPAddress(Int64) public long Address { get; set; } ``` This makes it possible to: - create an IPv4 IPAddress without allocating a byte[] which isn't stored - retrieve the IPv4 address bytes without allocating a byte[] - change the IPv4 IPAddress The property has been deprecated, probably because it doesn't work for IPv6. We can support these operations for both IPv4 and IPv6 using the Span type: API Proposal: ```c# IPAddress(ReadOnlySpan); // AddressFamily inferred from Span.Length IPAddress(ReadOnlySpan, long scopeid); // Span.Length must be IPv6 void GetAddressBytes(Span); // Span.Length must match AddressFamily* void SetAddressBytes(ReadOnlySpan) { SetAddressBytes(bytes, 0); } void SetAddressBytes(ReadOnlySpan, long scopeid); // allocates if AddressFamily doesn't match* bool Equals(ReadOnlySpan); // Span.Length must match AddressFamily*, scopeid not checked bool Equals(ReadOnlySpan, long scopeid); // Span.Length must match AddressFamily* ``` *: special handling for IPv4MappedToIPv6. 17379 area-System.Diagnostics Is there an EventSourceAnalyzer analog in dotnet core?

There has been a long-standing problem with SerialPort where the DCB fAbortOnError flag can get set somehow (by past problems with the port, how it gets set doesn't really matter) and is then not cleared by SerialPort when the port is opened in a .NET application. This changes the behaviour of the port so that it doesn't work correctly with SerialPort, because it's not expecting the fAbortOnError flag. There have been reports of this before [here](https://connect.microsoft.com/VisualStudio/feedback/details/584116) which have been closed as 'by design', which was, IMO, a mistake - or at least the reasoning given was incorrect. This needs a test in the test suite, and to be investigated to see: 1. Does the problem still exist 2. Is it really a SerialPort bug or do some USB ports behave differently to real ports 3. Regardless of '2', can the situation be improved by changes to SerialPort to be more defensive.

Remove `ConstValFactory.Copy` — Since `CONSTVAL` is immutable, aliasing instead of copying is safe. Make `ConstValFactory` completely static — Factory is not influenced by any state, overridden (or overridable) and has no scope for injection of a different factory service. Make it completely static and remove all factory allocations. Move `CONSTVAL` creation into `CONSTVAL` itself. — Allows it to have private constructors, ensuring they are not called directly (as comment on factory had suggested, but which was not enforced). Make `objectVal` an auto-property Rename `CONSTVAL` and its members. Rename to `ConstVal`, for more conventional .NET style. Rename `XXXVal` properties (e.g. `strVal`) to mirror .NET type names (e.g. `StringVal`). Use singletons for `true`, `false` and 0 (`int`) `ConstVals` — Reduce allocations for common and quick to identify cases.

" 17414 area-System.Memory Proposal: API changes to Span as part of shipping story "As part of productizing `Span` for pre-release - https://github.com/dotnet/corefxlab/issues/1314 / https://github.com/dotnet/corefxlab/issues/1292 - here are the proposed changes that became visible from the use of `Span` in [Kestrel](https://github.com/aspnet/KestrelHttpServer) and from design discussions of what APIs are useful versus what aren't ready to be shipped or not useful. ## Proposed API Additions ```C# public static class SpanExtensions { public static bool StartsWith(this Span span, ReadOnlySpan value) where T : struct, IEquatable public static bool StartsWith(this Span span, ReadOnlySpan value); public static bool StartsWith(this ReadOnlySpan span, ReadOnlySpan value) where T : struct, IEquatable public static bool StartsWith(this ReadOnlySpan span, ReadOnlySpan value); public static void CopyTo(this T[] array, Span span); public static ReadOnlySpan AsSpan(this string text); public static Span AsSpan(this T[] array); public static Span AsSpan(this ArraySegment segment); public static Span AsBytes(this Span source) where T : struct public static ReadOnlySpan AsBytes(this ReadOnlySpan source) where T : struct public static int IndexOfAny(this Span span, byte value0, byte value1); public static int IndexOfAny(this Span span, byte value0, byte value1, byte value2); public static int IndexOfAny(this Span span, ReadOnlySpan values); public static int IndexOfAny(this ReadOnlySpan span, byte value0, byte value1); public static int IndexOfAny(this ReadOnlySpan span, byte value0, byte value1, byte value2); public static int IndexOfAny(this ReadOnlySpan span, ReadOnlySpan values); } ``` ## Proposed API Removals ```C# public static class Span { public static Span AsBytes(this Span source) where T : struct public static ReadOnlySpan AsBytes(this ReadOnlySpan source) where T : struct public static Span NonPortableCast(this System.Span source) where TFrom : struct where TTo : struct public static ReadOnlySpan NonPortableCast(this System.ReadOnlySpan source) where TFrom : struct where TTo : struct public static ReadOnlySpan Slice(this string text); public static ReadOnlySpan Slice(this string text, int start); public static ReadOnlySpan Slice(this string text, int start, int length); } ``` ## Sample Usage and Rationale **Adding AsSpan and removing Slice:** There is not enough consensus whether a method named Slice should return a Span and not the same type that it extends. Furthermore, we want to be able to wrap an ArraySegment into a Span but having a Slice extension method on ArraySegment that returns Span could conflict with a Slice method that returns an ArraySegment. AsSpan more clearly identifies the usage and does not block the use of Slice as a method name. ```C# string s = ""Hello""; ReadOnlySpan span = s.AsSpan().Slice(1, 3); // Instead of: string s = ""Hello""; ReadOnlySpan span = s.Slice(1, 3); int[] a = { 91, 92, -93, 94 }; Span span = a.AsSpan(); // Enables a builder pattern approach, rather than having to do: int[] a = { 91, 92, -93, 94 }; Span span = new Span(a); // Similarly for ArraySegment ArraySegment segment = new ArraySegment(a, 1, 2); Span span = segment.AsSpan(); ``` **Removing NonPortableCast:** Are these APIs useful and do we want to ship them? We can add them if they are necessary. Currently, they are only used in Parsing and Encoding for casting from byte to char, exclusively. Example: https://github.com/dotnet/corefxlab/blob/c9423549a3e37a2b0de953dd20cf30558ebfca13/src/System.Text.Primitives/System/Text/Encoding/Utf16/Utf16TextEncoderLE.cs#L54 **Adding StartsWith:** It enables more readable, cleaner code. The user also does not need to do length checks. ```C# Span firstSpan = new Span(first); ReadOnlySpan secondSpan = new ReadOnlySpan(second); // You can write: bool b = firstSpan.StartsWith(secondSpan); // Instead of: bool b = firstSpan.Slice(0, secondSpan.Length).SequenceEqual(secondSpan); // You also have to do additional length checks first, i.e.: bool b = firstSpan.Length >= secondSpan.Length && firstSpan.Slice(0, secondSpan.Length).SequenceEqual(secondSpan); ``` **Adding IndexOfAny:** Used by Kestrel - System.IO.Pipelines. https://github.com/dotnet/corefxlab/blob/66f021b94e93fe36bc0446d9f23d5a3820dc36df/src/System.IO.Pipelines/ReadCursorOperations.cs#L41 https://github.com/dotnet/corefxlab/blob/66f021b94e93fe36bc0446d9f23d5a3820dc36df/src/System.IO.Pipelines/ReadCursorOperations.cs#L63 ```C# // We have: int index = span.IndexOfAny(byte0, byte1, byte2); if (index != -1) { result = new ReadCursor(segment, segmentPart.Start + index); return span[index]; } // If we don't have this, the alternative would be, something like: int index = span.IndexOf(byte0); index = index == -1 ? span.IndexOf(byte1) : Math.Min(index, span.IndexOf(byte1)); index = index == -1 ? span.IndexOf(byte2) : Math.Min(index, span.IndexOf(byte2)); if (index != -1) { result = new ReadCursor(segment, segmentPart.Start + index); return span[index]; } ``` **Adding Copyto:** This is a convenience extension method on array to avoid having to write a Span wrapper around the source array. ```C# var destination = new Span(new byte[100]); var source = new byte[] { 1, 2, 3 }; // You can write: source.CopyTo(destination); // Instead of: var sourceSpan = new Span(source); sourceSpan.CopyTo(destination); ``` Another related API proposal: https://github.com/dotnet/corefx/issues/16888 **Update:** ~- Changed AsSpan to SliceAsSpan and added overloads that take index and length.~" 17415 area-System.Net Rewrite Socket.AcceptAsync Task-based method on SocketAsyncEventArgs It's currently implemented on top of the APM implementation; this changes it to be implemented on top of the SocketAsyncEventArgs implementation.

Provide a robust API that allows developers to perform framework checks - In other words must not require parsing or comparisons by the developer. 2. Use terms the developer already uses when they do compile-time specialization using cross-targeting (""bait & switch"") - The strings passed to the API should be identical to the string used in project files and NuGet packages - In other words, we will not use the canonical TFM representation as it's wordy and generally not used by developers (e.g. `.NETFramework, Version=4.6.1`) 3. Design should allow for an API that we *can* put in-box - Our goal is to avoid having to ask library authors to depend on an extra NuGet package that they have to deploy just for light-up - Means we cannot have APIs that imply each time a new .NET platform (or version ships) all platforms have to update their implementation - In other words, an implementer should only have to correctly answer questions affecting itself, i.e. it shouldn't have to know how other platforms behave or what names they use. 4. API should work on .NET Framework 4.6.1 - That's the minimum platform we support with .NET Standard 2.0, so it will be a common target and hence needs to work 5. API should be addable to .NET Standard 2.0 - This makes (3) much nicer today - Effectively only means we cannot add members to a type that already exists in .NET Framework 6. The API must answer what the application *runs on* (as opposed to what the application is *built for*). - This is different from `AppContext.TargetFrameworkName` ### Decisions * Originally we considered having properties with well-known names (like `Net461`). Having those properties violates requirement (3). * We considered adding the API on a more-well-known type, such as `AppContext` or `Environment`. We believe this API to be quite specialized and should only be used as the last resort. As such, we don't want to overly emphasize its existence. Also, it would violate requirement (4) and (by extension) requirement (5). * We considered using `FrameworkName` instead of `string` but this would require `FrameworkName` to parse NuGet-style TFMs into their canonical representations, i.e. `FrameworkName.Parse(""net45)""` needs to be parsed into `FrameworkName { Identifier="".NETFramework"", Version=new Version(4, 5, 0, 0) }`. While that would be nice, it violates requirement (3). ### Context Today, we have the following APIs that return version numbers: ```C# namespace System { public static partial class AppContext { public static string TargetFrameworkName { get; } } public sealed partial class Environment { public static OperatingSystem OSVersion { get; } public static Version Version { get; } } } namespace System.Runtime.InteropServices { public static partial class RuntimeInformation { public static string FrameworkDescription { get; } public static Architecture OSArchitecture { get; } public static string OSDescription { get; } public static Architecture ProcessArchitecture { get; } public static bool IsOSPlatform(OSPlatform osPlatform); } } ``` Neither of them deal with concepts that the developer is familiar with when building the application, specifically the target framework names and version numbers (e.g. `net45` and `netcoreapp11`). Furthermore, their behavior is less than ideal. Here is the output from a .NET Core console app: ```C# Console.WriteLine(AppContext.TargetFrameworkName); // Console.WriteLine(RuntimeInformation.FrameworkDescription); // .NET Core 4.6.00001.0 ``` Our original design goal of `RuntimeInformation` was to provide developers with the diagnostic means to discover which .NET platform and operating system they are running on while not exposing version checking because it's a known area for creating fragile code. Unfortunately, the resulting API surface is now entirely insufficient for runtime light-up. For better or worse, we've have to accept that developers will have to write code that allows them to tweak the behavior at runtime. We need to expose APIs that make it easy for them to express framework checks." 17453 area-Microsoft.CSharp Teach the dynamic binder about tuple conversions "(Originally reported as part of https://github.com/dotnet/roslyn/issues/17851 and https://github.com/dotnet/roslyn/issues/12804) **Version Used**: Microsoft Visual Studio Community 2017 Version 15.0.26228.4 D15RTWSVC Microsoft .NET Framework Version 4.6.01586 **Steps to Reproduce**: Compile and run: ``` using System; class C { static void Foo((long, long) x, object y) => Console.WriteLine(x); static void Main() => Foo((0, 0), (dynamic) null); } ``` **Expected Behavior**: Program prints ""(0, 0)"". The target type (long, long) for the tuple literal (0, 0) is known at compile time, so the tuple literal should be converted to an instance of that type, rather than of (int, int), and dynamic invocation should succeed. It this kind of conversion is not feasible for some reason, then the compiler should issue a compile-time error, rather than allowing the program to fail at runtime. **Actual Behavior**: ``` Unhandled Exception: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: The best overloaded method match for 'C.Foo(System.ValueTuple, object)' has some invalid arguments at CallSite.Target(Closure , CallSite , Type , ValueTuple`2 , Object ) at System.Dynamic.UpdateDelegates.UpdateAndExecuteVoid3[T0,T1,T2](CallSite site, T0 arg0, T1 arg1, T2 arg2) at C.Main() ``` FYI @VSadov " 17454 area-System.Runtime Question: Calling Mac OS X Native APIs from .NET Core Hello, I'd like to call Mac OS X native APIs from .NET Core.

It is only used to store the remainder out parameter of `BigInteger.DivRem` calls. I am going to disable assembly-wide test parallelization to avoid this issue for now.

This issue is a good place to track the discussion of whether or not to include them for UAP, and if the decision is to remove them, then break all of the dependencies. I did to an initial try of removing them, and it is not trivial since it would mean changing their configurations from netstandard to platform-specific (netcoreapp and netfx) and do that as well for all assemblies that depend on them, which were quite a few. 17661 area-System.IO SerialPort: Background thread can have unhandled exceptions causing process termination `SerialStream` creates a background thread (entry method is `_eventRunner.WaitForCommEvent`) which has no protection against unhandled exceptions. In some messy tear-down situations (e.g. unexpected USB device removal) `ObjectDisposed` exceptions can be unhandled on this thread - this causes process termination which is clearly highly undesirable. A complete rework of the event handling is probably not a good move in the short-term, but a straightforward catch-all around the thread method would seem to be a good idea which is very low risk but fixes a problem which is tremendously difficult to remedy in application code. In discussions on #17396, @daflame76 has posted a stack trace showing this exception terminating an application. Automated test for this is unlikely to be feasible because the circumstances of the exception are so difficult to repro. This can be assigned to me - I'll work with @daflame76 to get a PR together. 17662 area-System.IO SerialPort: Clear fAbortOnError when port opens Fixes #17396 17666 area-System.IO SerialPort: Don't allow unhandled exceptions out of Background thread Fixes #17661 17667 area-System.Security Ensure S.S.Crypto.Cng package is getting created for 2.0 Cng has been removed from netstandard2.0, so the package version of it needs to exist again. https://github.com/dotnet/standard/pull/272 17668 area-System.Net CertificateValidationRemoteServer_EndToEnd_OK failed on OSX https://github.com/dotnet/corefx/pull/17664 ``` System.Net.Security.Tests.CertificateValidationRemoteServer.CertificateValidationRemoteServer_EndToEnd_Ok [FAIL] System.IO.IOException : Unable to transfer data on the transport connection: Operation timed out. ---- System.Net.Sockets.SocketException : Operation timed out Stack Trace: at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Net.Security/src/System/Net/FixedSizeReader.cs(56,0): at System.Net.FixedSizeReader.d__1.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Net.Security/src/System/Net/Security/SslState.cs(755,0): at System.Net.Security.SslState.InternalEndProcessAuthentication(LazyAsyncResult lazyResult) /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Net.Security/src/System/Net/Security/SslState.cs(725,0): at System.Net.Security.SslState.EndProcessAuthentication(IAsyncResult result) /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Net.Security/src/System/Net/Security/SslStream.cs(132,0): at System.Net.Security.SslStream.EndAuthenticateAsClient(IAsyncResult asyncResult) at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_debug_prtest/src/System.Net.Security/tests/FunctionalTests/CertificateValidationRemoteServer.cs(27,0): at System.Net.Security.Tests.CertificateValidationRemoteServer.d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) ----- Inner Stack Trace ----- Finished: System.Net.Security.Tests ``` 17669 area-System.Drawing Remove SystemColors from .NET Core As `SystemColors` is not in .NET Standard, it doesn't make much sense to have it in .NET Core, either.

Especially if the underlying stream is network based. When trying to create a responsive application in these circumstances, where long running operations that might never return can be cancelled to return control back to the user, the inability to cancel these operations in difficult. Currently the only real option is to fork the call into a fake cancellable operation that ends up ignoring original Task when a cancellation happens, with something like ThreadingTools.WithCancellation. But that leaves the reading Task (and potentially the stream and any continuations registered on it) floating, unreferenced. 17672 area-Meta More PNSE messages/comments in Process and Crypto @Priya91 can you please answer questions I put in the diagnostics files?

Unless I'm wrong (and if I am, please let me know), there's no way easy way to do this in .Net. It's one of the most useful pieces of technology that got washed away by the ""managed code"" model. Yeah; I guess if I wanted to drop back to native, unmanaged C++ I can still use memory mapped files, but that seems like a hack -- kind of like a donut spare on a sport/utility vehicle.

The use of the background thread has created problems with unhandled events escaping (see #17661 & #17666) and is also possibly some part of an close/re-open problem described in #16261 (I'm not sure if it is or isn't). It is worth investigating if we could change from a background `Thread` to `Task.Run` and then await the completion of this Task in the relevant dispose method. This would bring exceptions back properly where they can be sensibly handled, and would ensure that the thread was finished before returning from the dispose. At present no reference to the background thread is held by `SerialStream`, so it's impossible for it to make sure it's complete before finishing the close/dispose.

The proposal is to add a new attribute to `System.Runtime.CompilerServices` namespace similar to`InAttribuate` and `OutAttribute`, named `IsReadOnlyAttribue`. Example usages: 1) For read-only reference parameters. 2) For return types that are read-only references. 3) On read-only structs. # Proposed API ```csharp // .NET Core: // System.Runtime (reference assembly) // System.Private.CoreLib (implementation) // .NET Framework 4.7++ // mscorlib // .NET Standard 2.0++ // netstandard namespace System.Runtime.CompilerServices { [AttributeUsage(AttributeTargets.All, Inherited = false)] public sealed class IsReadOnlyAttribue: Attribute { public IsReadOnlyAttribue(); } } ``` 17742 area-Infrastructure Fix LinuxCross Portable Build Fixes https://devdiv.visualstudio.com/DefaultCollection/DevDiv/_build?_a=summary&buildId=649339 @weshaggard PTAL.

Really compiler _silently_ convert the char -> ushort -> int and use `StringBuilder(int capacity)` constructor. Sample http://ideone.com/1pPHlZ Currently we already have method `Append(char value)` so suggestion is to add new constructor `StringBuilder(char value)`. ## Proposed API ## ```c# public sealed partial class StringBuilder : ISerializable { // Proposed constructor public StringBuilder(char value); } ``` 17746 area-Infrastructure "Cannot use packages ""System.Runtime.Loader"", ""System.Reflection.Emit"" and ""System.Reflection.Emit.Lightweight"" when targeting netstandard2.0" I’m moving [PowerShell Core](https://github.com/powershell/powershell) to NetStandard2.0, and find that I cannot depend on the following packages when building an assembly targeting netstandard2.0: - [“System.Runtime.Loader”](https://dotnet.myget.org/feed/dotnet-core/package/nuget/System.Runtime.Loader) - [“System.Reflection.Emit”](https://dotnet.myget.org/feed/dotnet-core/package/nuget/System.Reflection.Emit) - [“System.Reflection.Emit.Lightweight”](https://dotnet.myget.org/feed/dotnet-core/package/nuget/System.Reflection.Emit.Lightweight) I’m targeting a very recent version of NetStandard.Library package (2.0.0-beta-25123-01), where the core/primitive types like `Systme.Object` have been moved to netstandard.dll.

This suggested that this is a test issue - that the tests are running parallel to each other and this causes failures. After investigation, it seemed that this is caused by trying to delete a file at the same time that it is being moved. This caused a race condition - but I'm not sure why it only occurs on desktop. The fix is to avoid moving and deleting sources. Instead, we can just refer to the original assembly instead of the new destination assembly. This also requires modifying the tests that expect a FileNotFoundException trying to access the original assembly - this is because we previously deleted it. This is not a problem, as we can modify the test data, and it has exactly the same meaning - trying to load an assembly that doesn't exist.

Here is a minimal but complete example that demonstrates the problem: ```csharp public static void Twice(ReadOnlySpan src, Span dst) { for (var i = 0; i < src.Length; i++) { dst[2 * i + 0] = src[i]; dst[2 * i + 1] = src[i]; } } [Fact] public static void Test1() { var src = new byte[] { 1, 2, 3, 4, 5, 6 }; var dst = new byte[] { 1, 2, 3, 4, 5, 6 }; Twice(new ReadOnlySpan(src, 0, 3), new Span(dst)); Assert.Equal(new byte[] { 1, 1, 2, 2, 3, 3 }, dst); // works! } [Fact] public static void Test2() { var src = new byte[] { 1, 2, 3, 4, 5, 6 }; var dst = src; Twice(new ReadOnlySpan(src, 0, 3), new Span(dst)); Assert.Equal(new byte[] { 1, 1, 2, 2, 3, 3 }, dst); // fails! actual value: { 1, 1, 1, 1, 1, 1 } } ``` It's a very small corner case, but it can lead to very subtle, hard-to-find bugs. The problem can be prevented in `Twice` by * making a defensive copy, or * adding a check if the two spans overlap. The copy is much more expensive, so it would be nice if it could be avoided. With `ArraySegment` arguments, the check can look like this: ```csharp public static void Twice(ArraySegment src, ArraySegment dst) { if (src.Array == dst.Array && src.Offset < dst.Offset + dst.Count && dst.Offset < src.Offset + src.Count) { throw new ArgumentException(); } for (int i = 0; i < src.Count; i++) { dst.Array[dst.Offset + 2 * i + 0] = src.Array[src.Offset + i]; dst.Array[dst.Offset + 2 * i + 1] = src.Array[src.Offset + i]; } } ``` This proposal is to add an API that enables similar checks for spans. ### Proposed API ```csharp public static class SpanExtensions { public static bool Overlaps(this ReadOnlySpan first, ReadOnlySpan second); } ``` *Open questions:* * Are overloads for all four combinations of `Span` and `ReadOnlySpan` needed * Should the name be `Overlaps` (like `Equals`) or `Overlap` (like `SequenceEqual`) * Should the method return `true` or `false` if one or both of the spans is empty * Should the method return the overlapping range rather than a `bool` * Does it belong in SpanExtensions * ... *Usage:* ```csharp public static void Twice(ReadOnlySpan src, Span dst) { if (src.Overlaps(dst)) { throw new ArgumentException(); // or src = src.ToArray(); } for (int i = 0; i < src.Length; i++) { dst[2 * i + 0] = src[i]; dst[2 * i + 1] = src[i]; } } ``` ### Prototype Implementation I've come up with the following implementation that I would use if there is no strong need for an official API. It's based on the current implementation of the [`SpanHelpers.CopyTo`](https://github.com/dotnet/corefx/blob/f17a94868f4a62c22c75b5710d19ab928f896e5e/src/System.Memory/src/System/SpanHelpers.cs#L23) method. ```csharp public static class SpanExtensions { public static bool Overlaps(this ReadOnlySpan first, ReadOnlySpan second) { ref T x1 = ref first.DangerousGetPinnableReference(); ref T y1 = ref second.DangerousGetPinnableReference(); ref T x2 = ref Unsafe.Add(ref x1, first.Length); ref T y2 = ref Unsafe.Add(ref y1, second.Length); // return (x1 < y2) && (y1 < x2) IntPtr diff1 = Unsafe.ByteOffset(ref x1, ref y2); IntPtr diff2 = Unsafe.ByteOffset(ref y1, ref x2); return (IntPtr.Size == sizeof(int) ? (int)diff1 > 0 : (long)diff1 > 0) && (IntPtr.Size == sizeof(int) ? (int)diff2 > 0 : (long)diff2 > 0); } } ``` It looks simple, but I'm not sure if it's correct. For example, is it legal to have `Unsafe.Add` return a `ref` past the end of a span if the `ref` is not dereferenced? ------ ### Update :boom: The above implementation has several bugs.

However, the types in `System.ValueTuple.dll` are already exposed from `System.Runtime.dll` when targeting `netcoreapp2.0`, and thus using any of those types results in ambiguous type identity error: ``` Program.cs(9,45): error CS0433: The type 'TupleExtensions' exists in both 'System.ValueTuple, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' and 'System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' [D:\apps\netcore2\test\test.csproj] ``` Here is a simple repro: ```c# using System; namespace test { class Program { static void Main(string[] args) { Console.WriteLine(typeof(System.TupleExtensions).FullName); } } } Exe netcoreapp2.0 win10-x64 ``` It looks `netcoreapp2.0` doesn't come with `Microsoft.CodeAnalysis.CSharp.dll` and `Microsoft.CodeAnalysis.dll`.

Reduces the amount of casting done, and the potential for mis-casting. * Make `Expr.Type` virtual. Only store when necessary, via new intermediate base class. Calculate when possible, or have default behaviour of returning null when not relevant for a given type of `Expr`. * Remove assignment of default values to fields of new objects in factories. These are no-ops, and removing them serves to simplify the factory methods. * Remove `ExprTypeOrNamespace` `ExprClass` is the only derived class, so remove `ExprTypeOrNamespace` and tighten declarations to just that, removing several casts no longer necessary and eliminating cases where a namespace could exist where a type is needed or vice versa. * Remove `ITypeOrNamespace` There are no longer any cases that could be either a `CType` or an `AssemblyQualifiedNamespaceSymbol`, so this interface no longer serves any purpose. 17800 area-Microsoft.CSharp De-spaghetti Microsoft.CSharp.RuntimeBinder.Semantics.ExprVisitorBase.VisitChildren The switch statement contains a lot of `goto` jumps.

Key data (values and subkeys) can change while we're in the midst of enumerating. This is causing intermittent failures in tests as ERROR_NO_MORE_ITEMS surfaces as an exception as we try and iterate past removed data. In addition, allocating 32K to get value names causes 32K * number of items to get natively allocated on the heap. While these allocs are returned on each iteration it could potentially cause significant grief for large keys and concurrent heap allocations. Above and beyond this, allocating 64K for what are typically < 20 character names is a bit crazy, and as such we'll optimize for the common case. Related to #17037, #16961- **however** this doesn't directly fix those as there is another copy of the registry code in System.Private.Corelib that those issues are actually using.

For example var block = new ActionBlock(a => a.Invoke()); block.Post(() => Console.WriteLine(""First Item"")); //Printed block.Post(() => Console.WriteLine(""Second Item"")); //Printed block.Post(() => throw new ApplicationException(""Throwing an exception here"")); block.Post(() => Console.WriteLine(""Fourth Item"")); //Not Printed block.Post(() => Console.WriteLine(""Fifth Item"")); //Not Printed When using the blocks to construct an asyncronous queue for items, this can cause issues. You need to recreate the block and re-post any queued items that have not been processed. The below suggestions provide some additional functionality to allow devs to dictate whether a DataBlock should shut down in the event of a fault. **Suggested Change** Consider adding a new `ExecutionDataflowBlockOptions` property to control how the block acts in faulting scenarios. For example: `new ExecutionDataflowBlockOptions() { ContinueOnTaskFault = true; }` (`false` by default to preserve existing functionality). This functionality would effectively shift responsibility for managing the block faults to the developer. If they want to stop the block, they can call either `Complete` or action a `CancellationToken`. **Alternative** Add a new `ExecutionDataflowBlockOptions` property to specify a Faulting action, e.g. `new ExecutionDataflowBlockOptions() { FaultAction = (args) => HandleFault(args); }`. In this case, args would contain a property akin to `IsFaulted` that the action can set to `false` if they do not wish the block to stop." 17872 area-System.ComponentModel Compat bug in System.ComponentModel.Annotations tests for invalid RangeAttribute params "Example test: ```cs [Theory] [InlineData(typeof(int), ""1"", ""3"")] [InlineData(typeof(double), ""1"", ""3"")] public static void Validate_CantConvertValueToTargetType_ThrowsException(Type type, string minimum, string maximum) { var attribute = new RangeAttribute(type, minimum, maximum); Assert.Throws(() => attribute.Validate(""abc"", new ValidationContext(new object()))); Assert.Throws(() => attribute.IsValid(""abc"")); } ``` On netfx this test passes - `Exception` is thrown.

Nothing to remove ### background The reports were generated by enabling ILLink (mono linker build from codegen team /cc @erozenfeld) and diffing the output. The diffs are from a Windows build and constrained to only assemblies that are part of NETCore.App. When the linker is enabled it will produce a ""PreTrim"" folder in the object folder of an assembly, for example `\bin\obj\AnyOS.AnyCPU.Debug\Microsoft.CSharp\netstandard\PreTrim\Microsoft.CSharp.dll`. To enable a central copy of the trimmed assemblies you can set the property `BinPlaceILLinkTrimAssembly=true`, This will copy all pretrimmed and trimmed assemblies to a folder under bin: `\bin\ILLinkTrimAssembly\netcoreapp-Windows_NT-Debug-x64`. To generate the reports linked in this issue you must have a copy of the AsmDiff.exe tool. This tool isn't yet available for core, see (https://github.com/dotnet/buildtools/issues/1420). If you have the desktop version of the tool you can enable the reporting by setting `AsmDiffCmd=` The linker can be enabled for any project (not just those in NETCore.App) by building with `ILLinkTrimAssembly=true` after https://github.com/dotnet/corefx/pull/17825 is merged. ## how to tackle a library Pick a library and make a note you're going to work on it. Open the html report above for the library. Look for lines in red. These are theoretically dead. Search for the code in the `src` folder of this repo and delete it. Continue through the report for the library and delete all the dead code like that. BUT there ere are some special cases: 1. This is a very common one. Anything with “const”, please ignore. These are all fields inlined by the compiler, we want to keep them in the sources. Typically ints and strings. 1. Anything that is “static string” in “class SR” is special. Instead of editing a C# file you must find the matching entry in the .resx file and remove that. The .resx file for a library is in `src\\src\Resources\strings.resx`. The build will regenerate SR after you do this. Ignore anything else in “class SR” -- there are several methods that may show up as dead. 1. Ignore any private parameterless constructors. We have these in the code to prevent accidentally instantiating the class, we want to keep them in the code. 1. Ignore any public parameterless constructors if there are no other constructors. These are not real. 1. Some code will not be under the library’s folder, it will be in src\common. This code may not actually be dead because another library may use it. Ideally, grep to see whether anyone else in the tree uses it -- if so, it can be deleted. Or, ignore it and we can do another pass later. 1. If the code is only used in Unix, UAP, etc do not delete it. It is likely not dead. You can tell whether it's of this type by being surrounded by eg `#if uap` or having a condition in the .csproj file like eg ` '$(TargetGroup)' == 'uap'""` After you have removed the dead code from a library, make sure it builds (run “msbuild” in the “src” folder for the library). If it does not, go backwards. If it does build, next check the tests build and pass (run “msbuild /t:buildandtest” in the “tests” folder). Again if they do not, retrace your steps. If that all looks good, you can put up a PR for the library. When the PR goes in, we can check it off here.

"It's only a problem with Microsoft components. I see a component in NuGet whose name looks interesting. I click on Project Site and I am immediately taken to the site for the project that produces the component, which explains what it is, etc. But not with Microsoft components. Here's a simple example. I see a component in NuGet called ""System.Threading.Tasks.Extensions"". I click on Project Site. It takes me to a generic docs site, the main page that has nothing to do with System.Threading.Tasks.Extensions. If I then search for System.Threading.Tasks.Extensions, I got lots of hits, none of which are for System.Threading.Tasks.Extensions, but System.Threading.Tasks instead. I do the search again, this time putting the component name in quotes, prepending a plus sign to indicate that I don't want to see any pages unless the exact name appears: +""System.Threading.Tasks.Extensions"" Now I am given a page that is about another component, value.types, that says I need System.Threading.Tasks.Extensions in order to use it. Googling or Binging ""System.Threading.Tasks.Extensions"" doesn't do anything either. Now, wouldn't it be better if System.Threading.Tasks.Extensions had a documentation page somewhere similar to MSDN, and if one does not exist, actually indicate it does not exist. If there's not docs, telling the user there's not docs is actually quite valuable. The user can stop looking for docs, and may be go elsewhere such as stackoverflow, forums or decide to look through the source. There's a reason why there's a ""project site"" link on nuget.org. It's supposed to take you to the specific page for that component.

The path only reachable for this operand being `ExprLocal` is hence unreachable. Remove it and those methods only reached through it.

Since this cannot change once the socket is open, we should cache this, as we do for RemoteEndPoint. (Or alternatively, we can get the endpoint directly from the result of the AcceptEx call, as we do for RemoteEndPoint. However, this may introduce some additional overhead in cases where LocalEndPoint is never accessed, so it's not clear this is the right tradeoff in all cases.) Retrieving the LocalEndPoint is not a common thing to do, so I don't think this issue is particularly urgent, but we should track it. (I hit this when doing the Kestrel-on-Sockets prototype -- for some reason Kestrel does seem to repeatedly retrieve the LocalEndPoint, and expects it to be cheap, which is not an unreasonable expectation. I worked around the issue by just caching the LocalEndPoint myself.) 17957 area-System.Net Need System.Net.Sockets tests for multicast We don't have any multicast tests that actually exercise the functionality. 17958 area-System.Net Fix IPv6 calls to GetMulticastOptionName in shim The wrong options were being set in the native shim due to an incorrect Boolean value.

(Note that I validated the repro in https://github.com/dotnet/corefx/issues/17870 failed before this change and passes after, but we have zero automated tests for multicast functionality, other than some surface area argument validation.

HSV stands for hue, saturation, and value, and is also often called HS**B** (B for *brightness*). (Emphasis my own) `System.Drawing.Color` has methods for `GetHue()`, `GetSaturation()`, and `GetBrightness()`. One might assume that these methods would then return values using the `HSV/HSB` format, however they do not. They are using `HSL`.

But IIRC, we’re not doing connection pooling, so it’s largely irrelevant, and we shouldn’t be throwing a PNSE from it, as it doesn’t really matter what the timeout value is. o EntityBody: We should be able to support this. It’s a matter of how long we wait in socket receives to receive the full body. o HeaderWait: Similarly, we can time how long it takes to receive and parse the headers. o IdleConnection: Not relevant if we’re not connection pooling… again, throwing PNSE here seems like overkill. o MinSendBytesPerSecond: We can also time this and do the appropriate calculations. This is all about the sends that we issue. - Likely can’t: o RequestQueue: I don’t believe we have access to the listen queue in the OS. 17978 area-System.Net System.NullReferenceException in System.Net.Http.CurlHandler.CurlResponseStream.SignalComplete(Exception error, Boolean forceCancel) We are seeing application crashes while running a .NET Core 1.1 application on Ubuntu with the following stack trace: ``` Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Net.Http.CurlHandler.CurlResponseStream.SignalComplete(Exception error, Boolean forceCancel) at System.Net.Http.CurlHandler.CurlResponseStream.Dispose(Boolean disposing) at System.Net.Http.CurlHandler.CurlResponseStream.Finalize() ``` As far as I can tell, throwing an exception inside `Dispose` is a pretty bad idea -- this is amplified by the fact that there is no way to catch the exception thrown by a finalizer. 17980 area-System.Net NullReferenceException thrown getting InputStream from HttpListener "```cs class Program { static async Task Test() { string uri = ""http://localhost:9200/""; HttpListener listener = new HttpListener(); listener.Prefixes.Add(uri); listener.Start(); using (ClientWebSocket client = new ClientWebSocket()) { UriBuilder uriBuilder = new UriBuilder(uri) { Scheme = ""ws"" }; Task serverContextTask = listener.GetContextAsync(); Task clientConnectTask = client.ConnectAsync(uriBuilder.Uri, CancellationToken.None); HttpListenerContext listenerContext = await serverContextTask; HttpListenerWebSocketContext wsContext = await listenerContext.AcceptWebSocketAsync(null); await clientConnectTask; HttpListenerRequest request = listenerContext.Request; Stream stream = request.InputStream; } listener.Stop(); } static void Main() { Test().Wait(); } } ``` Stack trace: ``` System.NullReferenceException : Object reference not set to an instance of an object.

Inline the constant values into expressions using them, and remove any code made dead by this. Since this removes `ExprThisPointer`, `ExprLocal` can now be sealed. Remove `CheckedContext`: Offers no more functionality over the base as the related properties are writeable there. Rename BindingContextBase.cs to BindingContext.cs More appropriate, and available after removing `CheckedContext`. Make `ReportUnsafeErrors` a property, and have it rather than `UnsafeErrorGiven` store state. Members to properties or auto-properties where appropriate. Move ctor asserts up to calling factory methods. Remove no-op assignments of defaults in ctors. Don't assign to CheckedNormal and CheckedConstant in ctor, as always to false.

That EasyRequest isn't yet associated with a MultiAgent. - The request is queued to the MultiAgent. - Between the time that the request is queued and it's handled, the associated CancellationToken has cancellation requested. - When the agent then processes the request, in ActivateNewRequest it'll see that cancellation has been requested and will immediately bail, before associating the easy request with the agent. - Everything is dropped and eventually finalized. At that point the response stream's finalizer is invoked, it calls SignalComplete(..., forceCancel:true), and that dereferences _associatedMultiAgent in order to issue a cancellation request... but _associatedMultiAgent hasn't yet been set. There's no reason _associatedMultiAgent's initialization needs to be deferred until the EasyRequest is picked up by the agent. We can instead make _associatedMultiAgent a readonly field that's initialized to the associated agent when the EasyRequest is constructed, so it won't be null even in such a situation. I've not actually been able to repro the reported issue, so this is a speculative fix, but is goodness regardless. I can't see any other way a null ref could happen in the finalizer as reported. I did also clean up a few accesses in the same method, but there's shouldn't be any way those could have caused a null ref, due to the locking and checking being employed.

In the first request I receive several cookies which should be sent back to the server on the second request. For demonstration purposes I have created a small PHP script that sends some `Set-Cookie` headers similar to the style I receive them from the actual application. The source code of this script is https://gist.github.com/Nothing4You/6623cda16eb2c2c5b4d3d9106b95a6ce. You can find a live version at https://hosting.rep.pm/cookietest.php. I have tested the script using a web browser (Firefox), curl (in a linux shell) aswell as using python requests, which all handle cookies and show me the expected output in the second request: ``` Cookie[test1]: test1value Cookie[test2]: test=2&value=2 Cookie[test3]: $test-3 Cookie[test4]: test4 ``` However, if I try to do the same thing using `System.Net.Http.HttpClient` it only sets the 2 out of 4 cookies. According to Visual Studio I'm using SDK version 1.1.1. HttpClient is the following version: ``` Assembly: System.Net.Http, Version=4.1.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a Assembly location: .nuget\packages\system.net.http\4.3.0\ref\netstandard1.3\System.Net.Http.dll ``` Example code: https://gist.github.com/Nothing4You/c04af6781f8520efb4921ef144733731 18015 area-Serialization Potential ArgumentNullException in Microsoft.XmlSerializer.Generator In Microsoft.XmlSerializer.Generator code, `TempAssembly._assembly` is never being assigned to and will alwaybe null.

This was found during the implementation of https://github.com/dotnet/corefx/issues/16585 which enables RSACryptoServiceProvider for Unix. It is likely an issue with native interop when passing in a key with no information. The tests all use Array.Empty for the data. Passing in null instead is caught earlier in managed code, so there is not an issue with that. Also, similar validation tests should be added to the common RSA tests instead, so that the classes in System.Security.Algorithms also are tested for this.

There was some refactoring to break apart the shared, windows-only and unix-only code. Also several files were renamed to have *.Windows.cs or *.Shared.cs, and Unix-only files were added with *.Unix.cs. 18025 area-System.Reflection Fix xunit name Fix https://github.com/dotnet/corefx/issues/17996 18026 area-System.Net Fix and enable NetworkStream.Dispose test on Unix Closes https://github.com/dotnet/corefx/issues/16611 cc: @geoffkizer 18029 area-Infrastructure CLI for Alpine is broken The CLI for Alpine claims to contain the 1.1.0 shared framework but it is not. It's some 1.0.0 version in a folder that's been renamed. This is causing anything that depended on 1.1.0 surface area / assembly versions to fail. 18033 area-System.Security Fix portable System.Security.Cryptography.Native EC2M issue We are building the portable dotnet core on the oldest Linux distro we support, which is currently RHEL7.2. But the OpenSSL on that distro doesn't support the EC2M functions and so it effectively disables them for the portable dotnet core on all Linux distros. This change fixes it by adding copies of declarations of the five missing functions to opensslshim.h if they are not found at the compile time. That enables the shim to be able to use those functions on all distros that support them. 18035 area-Infrastructure Move corefx onto the .NET Core 2.0 toolset "The latest version of buildtools allows a 2.0 CLI to be used. This change pulls in that version of buildtools and updates corefx to use the 2.0 CLI for restoring nuget packages and running our shared tools. * All of the project.json(.template) files under `external` have been converted to use `PackageReference` items directly defined in the depproj files. The versions for these references are based on pre-existing properties defined in dependencies.props. When we take future version update PR's, we should only see changes in that single file. * packageresolve.targets was modified so that the paths for the MSBuild project to be restored, as well as the ""project.assets.json"" file (the lock file, essentially). Note that the property for the projec to be restored is still called `ProjectLockJson`, although it represents an MSBuild project. I'll look into cleaning this up, I just need to make sure there's no stray references to ""ProjectLockJson"" remaining. * There are a bunch of new calls to `chmod` here and there. This is because .NET Core 2.0 (which we now restore all packages with, and run the build on) does not preserve executable flags in Unix files, by design. We need to mark our programs as executable before we try to use them. * NuGet now restores all packages into folders with lower-case names. This needed to be accounted for in a variety of different places. * ~~I've brought back the ""hack"" where we pre-build CoreFx.Tools.dll before running the full product build. This is necessary due to changes in the CLI. Technically this will go away when we move CoreFx.Tools.dll into buildtools.~~ Never mind. We don't need that. NOTE: This is not going to work on Alpine right now, because there is no 2.0 CLI being produced for it. Everything should be in place to do, so, though, so hopefully we can turn that on shortly. @ericstj , @weshaggard, @joperezr " 18036 area-System.Net HttpWebRequest.SendRequest fails on UAP due to settting MaxResponseHeadersLength The UAP specific code in https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/netcore50/System/Net/HttpClientHandler.cs will throw PlatformNotSupportedException if the MaxResponseHeadersLength is to set.

Error messages can be localisable, which means that tests that compare the message with a fixed string are locale-dependent. So far whenever I've needed to examine a message I've either looked for a particular substring (which will serve my needs right now too, but it set me wondering about general principles), or verified that messages from exceptions thrown one way match those thrown another.

I have seen many examples where code goes to great lengths trying to not retain runtime type objects - do not put types as keys (unless the type is a known primitive) in Dictionaries/Caches, do not cache delegates .... - That is with the assumption that retaining type objects will prevent assembly unloading. However, if I am not mistaken, only a few, if any, runtimes can actually unload types/assemblies. It would be helpful for the dynamic scenarios, to know if unloading is not possible and thus no need to worry about, for example, using type objects as keys in caches. # Proposed API (part of overall capability probing framework as in https://github.com/dotnet/corefx/issues/17116) ```C# public static readonly string CollectibleAssemblies = nameof(CollectibleAssemblies); ``` Any better name is more than welcome. Any already existing conventional way to probe for the above would be fine too. 18088 area-Infrastructure Downgrade warnings when referencing log4net in netcoreapp2.0 Copied from https://github.com/dotnet/corefx/issues/17278. log4net referenced a mix of 1.0 and 1.1 packages. When used in netcoreapp1.1 this didn't matter, since the netcore.app meta-package would lift all the packages up to 1.1. In netcoreapp2.0 this no longer happens due to our smaller package graph. The result is that the mix of 1.0 and 1.1 cause downgrade warnings when 1.1 package bring in the 1.1 lineup (Microsoft.NETCore.Targets). This is because the lineup brings in 1.1 versions for **all** split packages, including those 1.0 references from log4net. The 1.1 runtime packages reference 1.1 dependencies which ends up looking like a downgrade to nuget. We could fix this by shipping a new version of Microsoft.NETCore.Targets in netcoreapp2.0 which has no lineup info in its runtime.json. That would have the added benefit of reducing the download for mixed 1.x/2.0 projects, reducing the package graph, and thus our reliance on conflict resolution. The downside is that it would grow the package graph slightly. @weshaggard @terrajobst what do you think? 18091 area-System.Collections Add TryAdd/Remove extension methods in CollectionExtensions Adding `TryAdd` and `Remove` to `CollectionExtensions`.

So while implementing EntityFramework I found several inconsistencies in how DiagnosticListener is used in one repo. Issues for that (so far) are: - https://github.com/aspnet/EntityFramework/issues/7939 - https://github.com/aspnet/EntityFramework/issues/8001 - https://github.com/aspnet/EntityFramework/issues/8007 - https://github.com/aspnet/EntityFramework/pull/8110 - ...and I haven't even dealt with transactions and errors yet, which also don't have the bits needed for correlation. But when wrapping up Entity Framework and moving to port MVC from view wrappers (needed in MVC <= 5 days) to DiagnosticListener, I see even more inconsistencies. Here's a summary of the problems I, as a consumer, see with the API as it's applied currently: 1. The arguments sent to the listener (often [via `.SubscribeWithAdapter()`](https://github.com/aspnet/EventNotification/blob/248222ff54848ec7a8967a28eb26dfc1cf8b1fe4/src/Microsoft.Extensions.DiagnosticAdapter/DiagnosticListenerExtensions.cs#L10)) is *usually* an anoymous object. But to consume this object, your parameter types and names on unrelated methods need to match exactly. - How are users to even find these arguments, without digging through source? - What ensures these aren't breaking? This approach seems very brittle overall. - In Entity Framework [strong types exist](https://github.com/aspnet/EntityFramework/tree/f273711b5d8b20173e0769e56006576f3fcd2c72/src/EFCore.Relational/Internal), but they're all internal. Note that the unit tests use them. - Note that Entity Framework is working around easy consumption limitations in .NET Core reflection (https://github.com/dotnet/corefx/issues/4672) - Also of concern here: you can't use adapters where you can't use IL-emit for them, since that's how they're attaching at runtime. 2. Identifiers are sporadically available for correlation. For example https://github.com/aspnet/EntityFramework/issues/8007 addresses this issue with data readers in Entity Framework. Without an ID of some sort (EF uses a `Guid` on connections and commands), the linear nature of DiagnosticListener logging is without a way to correlate without adding far more overhead to the entire chain. For example we're talking about `AsyncLocal` as a workaround (which adds context switching overhead all the way down the pipe). What are we talking about here for 2 events *divided* that need correlation? I posit that allocating a `Guid` is almost *always* the cheapest possible option. Perhaps a correlation method should be built into the diagnostics framework itself. - How do we correlate events without these, cheaply? - How do we ensure a correlation method is consistently available? - As an example, ApplicationInsights uses AsyncLocal (according to @davidfowl, I haven't found this yet), and [only listens to `BeforeAction` in MVC](https://github.com/Microsoft/ApplicationInsights-aspnetcore/blob/develop/src/Microsoft.ApplicationInsights.AspNetCore/DiagnosticListeners/Implementation/MvcDiagnosticsListener.cs#L13). And [Glimpse also falls back to AsyncLocal](https://github.com/Glimpse/Glimpse.Prototype/blob/8565cd72024597fe9d8717c929aa253c3da9f399/src/Glimpse.Agent.AspNet/Internal/Inspectors/Mvc/MvcDiagnosticsInspector.cs). 3. Why aren't the names exposed? As examples: - In [ASP.NET MVC](https://github.com/aspnet/Mvc/blob/1e7972bd8f8c2724f6b81c7efa8775d980a5a130/src/Microsoft.AspNetCore.Mvc.Core/Internal/MvcCoreDiagnosticSourceExtensions.cs), the names are inline (not accessible properties). - In [Entity Framework Core](https://github.com/aspnet/EntityFramework/blob/dev/src/EFCore.Relational/Internal/RelationalDiagnostics.cs#L12-L30) the properties are cleanly declared, but `internal` and therefore useless. Note that they're exposed for sanity in the tests, though. These things together amount to a loose API that's not really friendly for consumption or testing. In many of the above cases, adjustments were made for unit tests to be sane. This consumption is **the same set of things any consumer would like to have**. I propose we make these changes across the board to MS libraries and enhance usability in 2.0: 1. Message values get a strong type 2. These strong types are public (so we can cast and compile against them) 3. The names of messages issued are public (**as constants**, so they may be used in `[DiagnosticName]`) The loose coupling (not even taking a reference on Entity Framework, for example) could still work where it did before with the adapters that exist today. But for those who want compile time checking (often you're taking a listener dependency chain to listen *for that specific thing* anyway), you'd have everything needed. This also allows several possibilities with the `System.Diagnostics` adapters overloads for cleaner code. For example, today I have this: ```c# [DiagnosticName(""Microsoft.EntityFrameworkCore.BeforeExecuteCommand"")] public void OnBeforeExecuteCommand(DbCommand command, string executeMethod, Guid instanceId, bool async) { // Available: Guid connectionId, DbCommand command, string executeMethod, Guid instanceId, long startTimestamp, bool async var timing = command.GetTiming(executeMethod + (async ? "" (Async)"" : null), MiniProfiler.Current); if (timing != null) { _commands[instanceId] = timing; } } ``` Instead, we could have this (while existing adapters continue to work): ```c# [DiagnosticName(RelationalDiagnostics.BeforeExecuteCommand)] public void OnBeforeExecuteCommand(BeforeExecuteCommandMessage message) { var timing = command.GetTiming(message.ExecuteMethod + (message.Async ? "" (Async)"" : null), MiniProfiler.Current); if (timing != null) { _commands[instanceId] = timing; } } ``` In that example I upper-cased the names for consistently in C# and framework patterns, but obviously that's an optional v2 break or not to be had. Note that the adapter could convert them camelcase matching for the proxy method if it struck out on an exact match for compatability. Also note that break would happen **at compile time**, and that it doesn't rely on conventions, the DLR, or runtime reflection to work.

I re-wrote a small piece of code within the F# compiler dealing with memory-mapped files to use ``MemoryMappedFile`` instead of the win32 API to allow that functionality to work on all platforms. Microsoft/visualfsharp#2528 The PR fails to build for CoreCLR, because the ``Read`` and ``ReadArray`` methods are missing on ``System.IO.UnmanagedMemoryStream`` (from which ``MemoryMappedFileAccessor`` is derived). Am I doing something wrong in the code or the package references? I've looked around in this repository and dotnet/coreclr and haven't found anything to indicate why those methods would be missing from the ``UnmanagedMemoryStream`` class (from the ``System.IO.UnmanagedMemoryStream`` package). 18120 area-System.Linq Fill some gaps in Expression.Invoke testing. 18121 area-System.Console Invalid input and output encodings are allowed by Console on Windows The following tests pass with netfx, but not with netcoreapp. I'm writing tests for this class and will attempt writing and submitting a patch for this behaviour. - Netfx: IOException thrown - Netcoreapp: no exception thrown - an invalid encoding (i.e. no such code page) is allowed.

I've got a few .NET services that run on machines with multiple IP addresses, and they need to occasionally send HTTP requests from specific IPs. Currently I use `HttpWebRequest` with a custom `ServicePoint.BindIPEndPointDelegate` and it works great. I'm hoping to port this service to .NET Core/Standard, but can't find any equivalent functionality in HttpClient/HttpClientHandler. Is there any way to control local IP to which HttpClient/HttpClientHandler binds? Any workarounds or plans to add this functionality?

Move files in Common only used in S.L.Expressions into S.L.Expressions @bartdesmet made a start on this with #14063 and #14097. This PR brings all remaining such files into System.Linq.Expressions. It also consolidates `System.Dynamic.Utils.Error` and `System.Linq.Expressions.Error`, so there is now one place for all such methods, which had previously been split between the two, with some duplicates. 18158 area-System.Net Added tests for EncryptionPropertyCollection (coverage 62.3%) Overall code coverage for System.Security.Cryptography.Xml is 71.8% Part of #16829 18159 area-System.Runtime Option/Maybe and Either ```csharp public Option GetById(string id) => new DbContext().Find(id); ``` instead of ```csharp public Employee GetById(string id) => new DbContext().Find(id); ``` The proposed method signature reveals much better the real intent of this method/function. Right? `Option` could provide a `Match` function.... Here is a very basic implementation: ```csharp namespace ElemarJR.FunctionalCSharp { using static Helpers; public struct Option { internal T Value { get; } public bool IsSome { get; } public bool IsNone => !IsSome; internal Option(T value, bool isSome) { Value = value; IsSome = isSome; } public TR Match(Func some, Func none) => IsSome ? some(Value) : none(); public Unit Match(Action some, Action none) => Match(ToFunc(some), ToFunc(none)); public static readonly Option None = new Option(); public static implicit operator Option(T value) => Some(value); public static implicit operator Option(NoneType _) => None; } } ``` with some additional operators: ```csharp namespace ElemarJR.FunctionalCSharp { using static Helpers; public static class Option { #region Of public static Option Of(T value) => new Option(value, value != null); #endregion #region Apply public static Option Apply (this Option> @this, Option arg) => @this.Bind(f => arg.Map(f)); public static Option> Apply (this Option> @this, Option arg) => Apply(@this.Map(Helpers.Curry), arg); #endregion #region Map public static Option Map( this Option @this, Func mapfunc ) => @this.IsSome ? Some(mapfunc(@this.Value)) : None; public static Option> Map( this Option @this, Func func ) => @this.Map(func.Curry()); #endregion #region Bind public static Option Bind( this Option @this, Func> bindfunc ) => @this.IsSome ? bindfunc(@this.Value) : None; #endregion #region GetOrElse public static T GetOrElse( this Option @this, Func fallback ) => @this.Match( some: value => value, none: fallback ); public static T GetOrElse( this Option @this, T @else ) => GetOrElse(@this, () => @else); #endregion #region OrElse public static Option OrElse( this Option @this, Option @else ) => @this.Match( some: _ => @this, none: () => @else ); public static Option OrElse( this Option @this, Func> fallback ) => @this.Match( some: _ => @this, none: fallback ); #endregion } } ``` and some LINQ support: ```csharp namespace System.Linq { using static Helpers; public static partial class LinqExtensions { public static Option Select( this Option @this, Func func) => @this.Map(func); public static Option SelectMany( this Option @this, Func> binder, Func projector ) => @this.Match( none: () => None, some: (t) => @this.Bind(binder).Match( none: () => None, some: (tb) => Some(projector(t, tb)) ) ); public static Option Where( this Option option, Func predicate ) => option.Match( none: () => None, some: o => predicate(o) ? option : None ); } } ``` This proposal does not incur any CLR changes. 18160 area-Infrastructure Individual library packages need netstandard2.0 configuration All our packages need to be sure to have netstandard2.0 support. 1. If they are part of netstandard2.0 then they need to have a placeholder so their owner assets doen't get chosen. 2. If they are above netstandard and they have an older netstandard configuration then they need a netstandard2.0 configuration to ensure package graph is cleaned up. @ericstj I filed this issue once I realized packages like our System.Net.Http will not work if they are referenced from a netstandard 2.0 project. 18161 area-System.Security Csp error strings missing error code parameter fixes https://github.com/dotnet/corefx/issues/11646 18162 area-Microsoft.CSharp Remove dead code from Microsoft.CSharp The only paths reaching `ExprArrayLength` and `ExprQuestionMark` were removed in #17948 so they can also be deleted, along with code that this in turn makes dead. Since `ExprArrayLength` obviously related to array lengths, add tests double-checking that still works (it does, because it isn't special-cased like it is with static code and is parsed like any other property). Also delete all the code identified as dead in #17905 that is really dead (not some constants), not in shared files, and not going to be deleted by #18004. 18163 area-System.Net Fix app-compat differences in System.Net.Requests Fix some product code behavior differences between .NET Core and .NET Framework (Desktop). Adjust tests. Disable more tests not working on Desktop. Fixes #18151. Contributes to #17842. 18164 area-System.Collections Add support for Data Contract Serializer to Immutable collections Immutable collections should support Data Contract Serializer like other collection types. Not supporting Data Contract Serializer makes Immutable collections unusable in Service Fabric applications. Considering the Service Fabric documentation suggests using immutable types it would be great if the ones supplied by MS worked. 18166 area-Serialization NS2.0 Finish XmlDictionaryWriter surface area. This override appears to be something that's supposed to be overridden by the actual implementation class by something decent, but in keeping with the desktop (and with methods like WriteValueAsync(IStreamProvider)), we'll provide a default implementation that satisfies the letter (if not quite the spirit) of the contract... 18169 area-System.Security Fix KeyInfoTest.ImportKeyNode Fixes https://github.com/dotnet/corefx/issues/16779 Previous version of the test was not Debuggable so I've split it so that we test individual components separately.

Fedora is returning error code 22 (EINVAL) for some recently added negative test(s) Fix is to check for EINVAL and if the last parameter of gethostbyname_r is either NO_DATA or HOST_NOT_FOUND then return HOST_NOT_FOUND. This results in a consistent return value across other unix flavors. 18171 area-System.Reflection Remove problematic test case This test case caused problems when additional tests are added to the project Fixes #14625 18172 area-Meta System.Json assembly identity We added System.Json with https://github.com/dotnet/corefx/pull/9897 and later updated the version number to match mono with https://github.com/dotnet/corefx/issues/9938. However we still haven't taken into account the public key. Currently it has the MSFT public key (soon to be the Open key https://github.com/dotnet/corefx/pull/18165) and so any existing binary references will still not bind to this assembly. We need to decide if we want this binary to exactly match the one we shipped with SL and if so we should give it the same complete assembly identity or we should rename it to a new assembly name and have it fall inline with any other new assembly in corefx. I think I would make it match the exact assembly identity. cc @stephentoub @terrajobst opinions? @karelz @danmosemsft do you know who owns this library? 18173 area-System.Net HTTPS perf issue on Linux/Ubuntu We have a sample app that uploads large files into Azure Storage on Linux (Ubuntu 16.10, .NET Core 1.1). When we use HTTP endpoint we get about 600MB/s throughput, whereas as soon as we change to HTTPS, the throughput drops to about 100MB/s. At first we thought this could be a bottleneck on Azure Storage, but after testing the same scenario with curl on Linux, as well as running the test on Windows, we concluded that this issue happens only with .NET Core on Linux when HTTPS is used. Using .NET Core on Windows, we get similar throughput around 600MB/s for both HTTP and HTTPS. And on Linux, we also tested this using a curl command and both HTTP and HTTPS provide similar results, hence raising the issue here. The sample app is here: https://github.com/seguler/azure-storage-throughput-test Any pointers on the issue ? @JeffreyRichter @polarapfel 18174 area-System.Threading Add test for thread pool concurrent initialization Depends on dotnet/coreclr#10869 Fixes dotnet/coreclr#10521 18175 area-System.IO Fix MMVS.PointerOffset to be correct This change fixes the PointerOffset property to be correct when the requested offset is larger than the allocation size of the OS.

This has the same content as the file we used to be automatically generating in init-tools.cmd/sh.

Assert.Throws(() => context.Response.OutputStream.Write(buffer, 0, buffer.Length)); // Closing a response from a closed client if a writing has already failed should not fail. context.Response.Close(); } } ``` It seems that closing the socket doesn't happen instantly, even though we waited for the GC, and then waited for finalizers to run. For some reason, this code doesn't work: ```cs client.Close(); GC.Collect(); GC.WaitForPendingFinalizers(); // Ooops. Client not closed. ``` From #17999: > @hughbe Socket.dispose, is calling safehandle.dispose. It could be the case that there were some references to the safe handle that prevents it from disposing, and with explicilty waiting for gc, that got disposed. Or it could be that the safehandle was put in finalizer queue, and the finalizer hadn't run to free up the resources before you tried to use the stream on the native connection. We need to find a better solution for what the test is trying to do: open a connection, then close the socket, then write to a closed socket. Could be the `using` block that is screwing things up for the GC? I have not encountered a failure on my PC yet in the current code. @stephentoub @Priya91 any ideas?

"Hi, I'm not sure I'm asking in the right place. I have a question regarding targeting. I created new console app using `dotnet new console`. Now, the project file looks like this: ``` Exe netcoreapp1.1 ``` Can I target `netstandard1.6` instead? Will it still run? Changing the project file to: ``` Exe netstandard1.6 ``` This builds using `dotnet build`. It doesn't run however. ``` Unable to run your project. Please ensure you have a runnable project type and ensure 'dotnet run' supports this project. The current OutputType is 'Exe'. ``` Is targeting .NET Standard only for libraries, not for executable binaries? I was hoping I could target a standard instead of any runtime and then choose a runtime of my liking to run that binary, as long as that runtime supports that standard version. Like choosing to either point `dotnet` or `mono` against a binary that targets netstandard. Is this even possible? And speaking of `OutputType` Exe, even in the original console project template, the build drops a dll, not an exe. Why is that? thanks, Tobias W." 18219 area-System.Net HttpContent.LimitArrayPoolWriteStream.Write causes a Grow on every call The code in the Write is: EnsureCapacity(_buffer.Length + count); The _buffer.Length is the size of the buffer, not the number of bytes written to it. So with this we're always asking for more than the buffer has room for, and thus we will call Grow. Grow is exponential (doubles the size of the buffer), so enough small writes into the stream will cause the Grow to ask for huge buffer and eventually run out of memory. The correct code should be: EnsureCapacity(_length + count); 18220 area-System.Console Disabled some System.Console tests from uapaot run since they were hanging In order to unblock the uapaot test run, we needed to disable a few tests from running in that framework since they were hanging.

This change is problematic for many reasons, mainly that HttpClient forces the user to reuse the same configuration across requests via `HttpClientHandler` and `HttpClient`. This would be quite alright for a REST focused library such as RestSharp, but (atleast in my opinion) is an outright _bad_ idea for the main HTTP solution in a major framework. This is a much smaller problem in the full .NET Framework as it fully supports both solutions. People who preferred to change these settings on a per-request basis could use `HttpWebRequest` and REST focused users could employ `HttpClient`. Some of the settings of `HttpWebRequest` I change on a regular basis are `Proxy`, `AllowAutoRedirect` and `Timeout`. These are some benchmarks I ran on the .NET Framework 4.6 (The leftmost number is the average time in ms. The `RestSharp` benchmarks are present just for reference.): ``` HttpWebRequest 70 | 70 69 70 70 70 69 71 70 71 73 71 69 71 69 70 70 70 70 70 69 HttpWebRequest-Async 69 | 67 69 72 69 67 69 70 71 67 70 70 69 70 69 70 69 68 71 71 70 HttpClient-Async 151 | 145 154 149 147 149 149 148 147 152 151 163 151 154 153 152 161 147 151 149 152 HttpClient-Async,Reused 72 | 154 74 69 60 62 72 67 70 72 60 70 64 63 70 63 72 71 72 71 73 RestClient 71 | 74 73 75 72 73 62 73 70 76 73 74 74 75 67 74 74 70 73 74 62 RestClient-Reused 70 | 72 71 71 72 59 70 70 70 70 71 70 71 70 71 71 77 74 72 72 73 ``` And the same benchmarks on .NET Framework 4.7: ``` HttpWebRequest 37 | 32 38 44 42 48 42 38 36 33 38 35 40 34 38 41 32 33 35 39 33 HttpWebRequest-Async 28 | 38 35 34 38 33 20 30 26 27 21 26 26 26 25 28 27 28 27 27 25 HttpClient-Async 48 | 46 48 45 51 46 46 52 45 48 48 46 48 48 46 48 46 46 46 70 58 HttpClient-Async,Reused 23 | 49 19 25 23 22 20 20 19 21 22 23 21 28 19 28 21 21 26 20 21 RestClient 38 | 53 48 42 39 40 38 41 43 39 44 40 36 41 40 35 37 37 20 27 36 RestClient-Reused 28 | 27 29 28 32 28 28 30 27 27 30 28 26 26 27 27 27 27 37 40 28 ``` The above benchmarks are from a Windows 10 system running the creators update. The requests were made to a 6KB resource on a CDN. The tests were run on different hardware from different locations, but since I'd like to focus only on their relative performance, this should not be a problem. Please correct me if I'm wrong. The most glaring difference between the two benchmarks is that .NET 4.7 optimized creating new `HttpClient` instances greatly (On .NET 4.6, the `HttpClient` row was consistently 150ms+). Note that while I was able to compile `2.0.0-preview1`, I have not tested the above on it. The .NET framework appears to use a different approach (Seen at https://referencesource.microsoft.com/#System/net/System/Net/HttpWebRequest.cs). Please consider using a similar approach. Using an `HttpClient` under the hood of an `HttpWebRequest` seems more like a duct-tape solution just in the interest of maintaining compatibility. I would argue it does not accomplish this anyway, since programs that worked well on the .NET Framework would appear to work on .NET Core, only for the developers to find performance issues with no clue as to their cause (Creating a new `HttpClient` took almost 20ms more each request than `HttpWebRequest`!). As as aside, I can imagine code as such as the following would causes deadlocks in cases where the synchronization context needs to be maintained (but I'm not sure if this case is handled elsewhere). ``` public override Stream GetRequestStream() { return InternalGetRequestStream().Result; } ```
**UPDATE**: These are the .NET Core 1.1 benchmarks on the same system as .NET 4.6 above. ``` HttpClient-Async 209 | 208 210 207 212 205 207 212 218 211 210 214 210 205 200 209 217 214 205 215 203 HttpClient-Async,Reused 72 | 204 58 73 66 61 58 60 60 69 67 58 69 60 72 70 69 70 66 70 70 RestClient 216 | 218 212 229 221 212 219 212 209 204 213 212 212 218 219 219 220 223 220 211 217 RestClient-Reused 215 | 208 213 211 211 221 227 211 214 214 220 213 210 219 218 210 217 211 231 215 225 ``` I used the `RestSharp.NetCore` package in the test above, which uses `HttpWebRequest` internally (Which in turn creates new `HttpClient` instances under the hood). The performance hit is clear. `RestClient` takes around 8ms longer for its own code. 18238 area-Serialization XmlSerializer to Support XmlMembersMapping via Reflection This PR enable XmlSerializer to support XmlMembersMapping via reflection (without using ILGen).

Related issue: https://github.com/dotnet/core-setup/issues/1411 18257 area-System.IO Suggestion: NamedPipe classes should support interop with other languages on Unix Currently, as far as I can tell at least, there is no good way to interop with a node.js/C++/etc with the .NET Core pipe code on non-Windows platforms. The problem is that on Unix you would like to get the full path to the underlying domain socket and somehow be able to open an arbitrary domain socket. But .NET Core doesn't have any APIs for this. In node.js, for example, `net.createServer` ([examples](http://stackoverflow.com/questions/11750041/how-to-create-a-named-pipe-in-node-js)) provides one abstraction that works with named pipes and Unix domain sockets. It does require a few lines of platform-specific code to work out the server name correctly. But once that is done you have code that is nice and unified and can interop with any other framework. Suggestions: 1. Named pipe server should have a method to get the underlying full pipe name 2. Named pipe client and server should have overloads that allow specifying the full pipe name 18259 area-Serialization Add two desktop test cases and some reference files for DataContractSerializer test "@shmao @huanwu Add two desktop test cases and some reference files for DataContractSerializer test.

However if we wanna do inserting/updating bytes into the file, we have to fetch some bytes from the file into a temporary one and then continue to do what we want... But if a file is size of GB-based.... It WON'T be a nice idea to do something like this way! I don't know whether Microsoft have nice ways to enhance the functions of FileStream/MemoryStream……ect. However I think it would be better if we now have: 1) FileStream.Insert(byte[] bytes,int startIndex,int endIndex): This is a very very useful method as far as I see——I have to save temporary binary bytes into MemoryStream. However compared with this for large files, it isn't a good way. Because we need a ""rapid-in/rapid-out"" method to direct do ""insert"". Maybe the ""bytes"" is the whole thing to be written into the binary file, startIndex: the position where the byte inserted. endIndex: to write how many bytes. 2) byte[] FileStream.Delete(int startIndex,int endIndex): Direct deleting some bytes from the file with an auto saving rapidly. The return value is the deleted bytes. --- @mikedn commented on [Sat Sep 17 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247762101) > But if a file is size of GB-based. If a file is large then you simply don't insert/delete byte into/from it. Inserting a single byte at offset 1 of a 1GB file requires you to copy 1GB worth of data, there's no magic around that. Any design that requires such insertion/deletion is simply a bad design and the framework has no reason to provide support for that. > I have to save temporary binary bytes into MemoryStream I don't see why you need a MemoryStream for that. If the file is large then you probably don't want to load it in memory. And if you really must insert something into the file then you can simply copy the data after the insert position using a trivial read/write loop. --- @MaleDong commented on [Sat Sep 17 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247762816) @mikedn ：Yes, that's the problem——I couldn't agree with you any more on this:) Certialy it seems that we cannot do inserting/deleting to a binary file with a huge size. And we cannot copy the whole rest bytes into the memory. This means it is hard if we wanna cope with bytes for a large file. The reason why I hope this is that if we wanna add some specific symbol as the ""head"" for my specific file (e.g: for the 1st time when I download a resource from the remote server, I wanna write the url address into the binary file with binary formation. However I must delete that to restore what it is later with the downloaded bytes after the symbol head....). This is ONLY an example, and such things are always happening: Imaging that if we wanna make a specific kind of binary file with certain head inside specific position and then our program can analyze that or mark that..... And if the file is very large. What can you do? Hope you can understand what I said. And what's more：In Visual C++ (Perhaps I'm NOT familiar with C++……). We have such functions as ""CreateFileMapping"" and ""MapViewOfFile"" can easily help us jump over some bytes and read next bytes.... So our C# should also have so easily methods to cope with them. --- @mikedn commented on [Sat Sep 17 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247798339) > What can you do? Hope you can understand what I said. No, I don't understand. As far as I can tell you're asking for something that can't be implemented efficiently and that isn't needed anyway. Databases can store terrabytes of data in binary files without requiring the ability to insert/delete stuff in the middle of the file. > We have such functions as ""CreateFileMapping"" and ""MapViewOfFile"" can easily help us jump over some bytes and read next bytes.... I don't understand what file mapping has to do with ""jump over some bytes and read next bytes"". You can do the same thing with a stream by setting the position appropriately. And file mapping doesn't allow you to insert/data data in the middle of the file. .NET exposes file mapping functionality via [MemoryMappedFile](https://docs.microsoft.com/en-us/dotnet/core/api/system.io.memorymappedfiles.memorymappedfile#System_IO_MemoryMappedFiles_MemoryMappedFile). --- @MaleDong commented on [Sat Sep 17 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247814772) > Databases can store terrabytes of data in binary files without requiring the ability to insert/delete stuff in the middle of the file. However I don't need db at all... What I wanna do is just to directly controlling with a binary file with a huge amount.... Since MemoryStream and memory isn't suitable for me. So how can I cope with that? > And file mapping doesn't allow you to insert/data data in the middle of the file. .NET exposes file mapping functionality via MemoryMappedFile ``` static void Main(string[] args) { long byteLen = 0; using (FileStream fs = new FileStream(""c:\\Try.txt"",FileMode.Open)) { byteLen = fs.Length; } //Now we can map our large file into memory and insert some new chars using (MemoryMappedFile mpf = MemoryMappedFile.CreateFromFile(""c:\\Try.txt"",FileMode.Open,""Try"",byteLen+4)) { MemoryMappedViewAccessor access = mpf.CreateViewAccessor(); byte b = 0; //Do shifting to the empty memory for (long i = byteLen-1; i >=0; --i) { b = access.ReadByte(i); System.Console.WriteLine((char)b); access.Write(i+4, b); } //Write down the correct position by inserting new chars var bytes = Encoding.ASCII.GetBytes(""abcd""); //Leave the whole memory for the file and write them directly for (int i = 0; i < bytes.Length; i++) { access.Write(i, bytes[i]); } access.Flush(); } } ``` Now from the codes you can see that I can directly do inserting. Deleting can be also done with such a trick.... However what I'm worrying about is: 1) I still have to copy the byte one by one to shift it to ""empty memory"" into the file 2) My file gets small, however if the file is very large. How can I cope with that? I still have to map the whole file to the memory.... Since Microsoft has added the nice function since net framework 4.0, and it can let us easily directly to cope with files such as what we are doing in the memory……Why don't you offer inserting/deleting functions? It would be very easy for us to Read/Write binary files for certain bytes. --- @mikedn commented on [Sat Sep 17 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247827564) What part of ""As far as I can tell you're asking for something that **can't be implemented efficiently** and that isn't needed anyway"" wasn't clear? --- @MaleDong commented on [Sun Sep 18 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-247834936) I see……However we really cannot find any other ways to do inserting/deleting bytes for a large file except for it that we have to save bytes into memory first?

I told you before that you can do this using a `FileStream` and a simple read/write loop to move the part of the file that's after the insert/delete position. After all, if you load the file in memory, you would do the same thing. > And if not, so if you meet this problem. How will you process with that? Binary file formats that require data to be inserted/deleted typically use fixed size pages. An ""entity"" is stored in multiple pages that are linked together in a linked list, B-tree or other suitable data structure that allows fast page insertion/removal. --- @MaleDong commented on [Tue Sep 20 2016](https://github.com/dotnet/coreclr/issues/7243#issuecomment-248305059) > An ""entity"" is stored in multiple pages that are linked together in a linked list, B-tree or other suitable data structure that allows fast page insertion/removal.

Are you thinking of adding a convenience method for doing the 2 operations (delete/insert)? Or are you asking for an efficient way of implementing those 2 methods? --- @MaleDong commented on [Sun Mar 05 2017](https://github.com/dotnet/coreclr/issues/7243#issuecomment-284313498) Thanks @AlexGhiondea for your quick reply！ If possible, Efficient way with the two methods is fine. If not, Offering Insert/Delete for direct-byte controlling is also nice. --- @AlexGhiondea commented on [Mon Mar 06 2017](https://github.com/dotnet/coreclr/issues/7243#issuecomment-284483437) I see. I don't believe there is a generic efficient approach for insert/delete. Could you give me more data about when those methods would be used? I am trying to see if there is enough value to consider adding them to the framework. --- @MaleDong commented on [Tue Mar 07 2017](https://github.com/dotnet/coreclr/issues/7243#issuecomment-284663923) A typical example is: When we wanna make a memory-based file (something similar to MemoryMappedFile), but we may check for some special bytes and do inserting/deleting at some specific positions to make a mocking memory data for dmp or log…… We don't directly control with memory but using ""MemoryFile"" instead. But now we cannot do direct insert or delete. --- @AlexGhiondea commented on [Tue Mar 07 2017](https://github.com/dotnet/coreclr/issues/7243#issuecomment-284667114) Thanks for the example. It is a bit vague, but it sounds more like a solution would look more like a convenience method and would apply in a small number of scenario. I don't believe there is a generic solution that we can introduce for this problem since, in order to make the insert/delete operations fast you need domain knowledge of how you are going to use those files. Because it requires domain specific knowledge/decisions I don't believe this is a good fit for the framework. --- @danmosemsft commented on [Wed Apr 12 2017](https://github.com/dotnet/coreclr/issues/7243#issuecomment-293778745) Moving to corefx as this is an api request.

The new CertificateRequest class allows a caller to set all of the fields in an X.509 v3 certificate, with the exception of the v2 IssuerUniqueId and SubjectUniqueId fields, as they are considered deprecated. Accelerators exist for self-signing, as well as chain-signing given an existing X509Certificate2 instance with a private key already associated. This change also adds CopyWithPrivateKey(this X509Certificate2 cert, {RSA|DSA|ECDSA} key) to enable scenarios where a public cert and private key are held independently but a unification is desired. This makes UNIX-style .pem/.key loading easier, but still requires users understand how to load the .key file. Fixes #17892. Fixes #7129. Fixes #14284. 18345 area-System.Linq Remove unresolvable directive from System.Linq.Expression.rd.xml Since System.Linq.Expressions doesn't have Microsoft.CSharp in its closure, so it should not have directives for types from it, since those directives might not be always resolvable. 18347 area-System.IO ZipFile.CreateFromDirectory(...) file locked after creation. File handle leak? Platform: Windows 7 Symptom: zipfiles I create are not available to be moved by the os after creation until the program ends. Analysis: When ZipFile.CreateFromDirectory(...) calls ZipFileExtensions.DoCreateEntryFromFile(archive, ...) the ZipArchiveEntry is created with the following code (~line 220): ZipArchiveEntry entry = compressionLevel.HasValue ? destination.CreateEntry(entryName, compressionLevel.Value) : destination.CreateEntry(entryName); But the ZipArchiveEntry that destination.CreatEntry(...) returns is an IDisposable object that is not wrapped with a (using ...) statement. Is this a handle leak?

This switches indexing to use VSTS Symbol. It handles hosting, so the builds don't need to copy to a file share. For release branch builds, archiving performance (still using the file share) is improved by https://github.com/dotnet/buildtools/pull/1421. The time this leg's steps take for a daily/indexed build is now: * 6.4 minutes Extracting * 1.5 minutes Publishing (indexing) * Total: 7.9 minutes I removed the symbol publishing steps from the Windows build legs because they're redundant. Removing the publish target path from the index+publish step means it will only index sources for the symbols and won't copy them anywhere. (Edit: on a test build I see that this step is only finding 2 PDBs, and it isn't able to find sources for them. Getting symbol indexing working properly is tracked by https://github.com/dotnet/core-eng/issues/499.) 18352 area-System.Diagnostics Modules_GetMultipleTimes_ReturnsSameInstance test failed in CI https://ci.dot.net/job/dotnet_corefx/job/master/job/windows_nt_debug_prtest/6248/consoleText ``` System.Diagnostics.Tests.ProcessModuleTests.Modules_GetMultipleTimes_ReturnsSameInstance [FAIL] System.ComponentModel.Win32Exception : Only part of a ReadProcessMemory or WriteProcessMemory request was completed Stack Trace: D:\j\workspace\windows_nt_de---4526f5ff\src\System.Diagnostics.Process\src\System\Diagnostics\ProcessManager.Windows.cs(400,0): at System.Diagnostics.NtProcessManager.GetModules(Int32 processId, Boolean firstModuleOnly) D:\j\workspace\windows_nt_de---4526f5ff\src\System.Diagnostics.Process\src\System\Diagnostics\ProcessManager.Windows.cs(294,0): at System.Diagnostics.NtProcessManager.GetModules(Int32 processId) D:\j\workspace\windows_nt_de---4526f5ff\src\System.Diagnostics.Process\src\System\Diagnostics\ProcessManager.Windows.cs(107,0): at System.Diagnostics.ProcessManager.GetModules(Int32 processId) D:\j\workspace\windows_nt_de---4526f5ff\src\System.Diagnostics.Process\src\System\Diagnostics\Process.cs(312,0): at System.Diagnostics.Process.get_Modules() D:\j\workspace\windows_nt_de---4526f5ff\src\System.Diagnostics.Process\tests\ProcessModuleTests.cs(50,0): at System.Diagnostics.Tests.ProcessModuleTests.Modules_GetMultipleTimes_ReturnsSameInstance() ``` cc: @hughbe, @danmosemsft 18353 area-Infrastructure Small crossgen.sh fixes - crossgen.sh was failing on OSX because the RID in the package that contains crossgen had changed. - crossgen.sh would try to crossgen the existing mscorlib.ni.dll and that would lead to a file in use error, I updated it such that it never tries to crossgen existing ni's.

I've searched various sites, blogs and the topic appears to be somewhat complex... at least from my country bumpkin perspective 😄 I came across the @AArnott and @terrajobst [video/blog](https://blogs.msdn.microsoft.com/dotnet/2013/09/25/immutable-collections-ready-for-prime-time/), read @ericlippert's [blog](https://blogs.msdn.microsoft.com/ericlippert/2012/06/08/persistence-facades-and-roslyns-red-green-trees/) on topic and attempted to understand Roslyn's [SyntaxNode](http://source.roslyn.io/#Microsoft.CodeAnalysis/Syntax/SyntaxNode.cs,849dc6029695ef7b)/[GreenNode](http://source.roslyn.io/#Microsoft.CodeAnalysis/Syntax/GreenNode.cs,85387470c0225abf) implementation (which is far more complex than my needs/comprehension). I think the [System.Immutable.Collections APIs](https://www.nuget.org/packages/System.Collections.Immutable) are an incredible start and provide great capabilities. However, they appear to stop short of offering similar parent/child management. It would be nice to have an additional immutable parent/child API. This parent/child relationship is nothing more than similar discussions on [Stack Overflow](http://stackoverflow.com/questions/6613613/in-c-sharp-4-0-is-there-any-way-to-make-an-otherwise-private-member-of-one-clas). I (like many others) need the ability to instantiate immutable parent objects, attach child(ren) objects, search up/down the tree (ancestors/descendants) and most importantly... update the objects' relationship when adding/updating/removing objects respectively (upstream or downstream). Meaning, once a child has been modify... the [Parent](http://source.roslyn.io/#Microsoft.CodeAnalysis/Syntax/SyntaxNode.cs,efecb528c7d2c282,references) is updated accordingly. I'm including a few of the smarter peeps I could think of to reach out to: 1. See if there is already related capabilities included with .NET Standard (or elsewhere compatible with .NET Standard) or 2. Possibly start the conversation/action to add this as a first-class offering with .NET Standard.

Those two methods are: - `public static System.Xml.XPath.IXPathNavigable ToXPathNavigable(this XmlNode node)` This method is not needed anymore as XmlNode now implements IXPathNavigable. - `public static System.Xml.XPath.XPathNavigator CreateNavigator(this XmlDocument document, System.Xml.XmlNode node)` which used to be internal on Desktop and I'm assuming was made public only to keep things working when Xml was split between different contracts.

The closed source .NET ToF test tree had a concept of *capabilities* that could be mapped to a set of *target runtimes*. What you could do with that was to say a test *requires* a capability and a *target runtime* could say that it *provides a capability*. When you had a test (such as e.g. a test exercising Rank 1 multidimensional arrays), you could say that the test is only applicable to runtimes that support Rank 1 multidimensional arrays. When a runtime added support for a capability, you would only need to update the list of it's capabilities, and all applicable tests would magically start running. Conversely, if a new target runtime was added, you only had to specify a list of it's capabilities and all the applicable tests would start running instead of having to dig through failures and trying to understand them. `SkipOnTargetFrameworkAttribute` seems to be inferior to the capabilities concept in every possible way: now you need to enumerate every possible runtime that the test is not supported on in the test itself. When the runtime learns that new feature, you better make sure and go over all the tests that were blocked for that particular runtime to make sure you're actually getting the test coverage you would expect for the new feature. 18402 area-System.IO Fix S.IO.FileSystem.DriveInfo running on uapaot 18403 area-System.IO Fix S.IO.FS.Performance tests on uapaot 18404 area-System.Net Retry ping when the output was not in expected syntax.

Ping works here because it usually takes a while to exit. ## Expected behavior The program starts a process, prints out ""Process started"", and terminates. ## Actual behavior When executed via `dotnet run`, the program does not terminate until the ""ping"" process terminates. Executing `killall ping` causes the `dotnet` process to terminate, as well, once `ping` has been killed. When I run the same program using corerun or coreconsole, the above behavior is not exhibited. A ping process is started, but the program immediately terminates. Ping continues in the background. ## Environment data `dotnet --info` output: ``` .NET Command Line Tools (1.0.0-rc2-002543) Product Information: Version: 1.0.0-rc2-002543 Commit Sha: 38d0c28a1e Runtime Environment: OS Name: ubuntu OS Version: 15.04 OS Platform: Linux RID: ubuntu.15.04-x64 ``` _Copied from original issue: dotnet/cli#2776_ --- @livarcocc commented on [Thu Mar 16 2017](https://github.com/dotnet/core-setup/issues/1762#issuecomment-287265358) _From @mellinoe on April 29, 2016 21:43_ Another point of data: If I execute `dotnet `, then the correct behavior is exhibited.

I did this as a quick experiment locally and it produces a better result. In most cases however these tests are still well optimized by the JIT. For example, this is the ""fixed"" JIT output for the ```IntPtr(0)``` constructor case: ``` E89EDEFFFF call BenchmarkIteration:StartMeasurement():struct:this 90 nop G_M39768_IG05: 33C9 xor ecx, ecx G_M39768_IG06: 33D2 xor rdx, rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx 48895618 mov qword ptr [rsi+24], rdx FFC1 inc ecx 81F910270000 cmp ecx, 0x2710 7CD0 jl SHORT G_M39768_IG06 ``` It's not clear that's a particularly valuable test. cc @ianhays as you seem to have written (or at least checked these in originally.)

" 18418 area-System.Diagnostics Activity: RootId based sampling When Activity starts without internal 'Parent' or external `ParentId`, it generates Id in the following way: `|MachineName-timestamp-number.` Where - `timestamp` is the last 32-bits of static start time of process (service instance) - `number` is monotonically incremented long with random start value As a result Ids generated for the consecutive requests from one instance look like ``` |Service1-36ef1287-1ad6aa. |Service1-36ef1287-1ad6ab. |Service1-36ef1287-1ad6ac. |Service1-36ef1287-1ad6ad. ``` They all have the same beginning and only few last characters differs. It is natural to sample requests based on the `Activity.RootId` since it ensures consistent sampling for the operation traces. **It could be the problem for the hashing algorithms used for sampling** E.g. djb2 [wiki](https://en.wikipedia.org/wiki/Universal_hashing#Hashing_strings), [sample implementation](http://www.cse.yorku.ca/~oz/hash.html) favors first characters over the last ones. ApplicationInsights uses it to sample telemetry items, so Id of the particular Activity almost always appear in the same hash bucket for the given service instance. In case of small cluster (e.g. 1-2 instances), it is likely all Ids will share the same hash bucket. In case of large cluster, it is still likely that machine names are quite similar and differ only with the last few characters, so distribution of hashes may still be far from uniform. I'd like to highlight that it mostly affects small clusters and only in case when clients (client apps or pages) do not generate the first Id, however it is common case for ApplicationInsights and perhaps other tracing systems. **So, 'root' Id generation should be revised, to make sure existing sampling/hashing algorithms would be able to use it and achieve close to uniform distribution. It implies that 'root id' should be random, at least it's first and last part.** /cc @vancem @cwe1ss @Dmitry-Matveev @SergeyKanzhelev 18419 area-System.Memory Fix CopyTo(this T[] array, Span destination) for covariant arrays CopyTo was creating writeable Span where it should have been only creating readonly Span. It made it slower than necessary for reference types because of the covariance check in writeable Span constructor, and also made it fail for no good reason on covariant arrays. 18420 area-System.Memory API Proposal: Span AsReadOnlySpan(this T[]) extension method #17414 added extension methods that make it easy to create Span from array using fluent pattern. This proposal adds similar methods for ReadOnlySpan. ```c# public static class SpanExtensions { public static ReadOnlySpan AsReadOnlySpan(this T[] array); public static ReadOnlySpan AsReadOnlySpan(this ArraySegment segment); } ``` Note that creating ReadOnlySpan directly using these APIs is not equivalent to creating Span and than casting it to ReadOnlySpan.

Just like `Comparer` provides a convenient `Default`, it would be great to also provide such a structural comparer, which is basically: ```c# public class StructuralComparer : IEqualityComparer { public static IEqualityComparer Default { get; } = new StructuralComparer(); public bool Equals(T x, T y) => StructuralComparisons.StructuralEqualityComparer.Equals(x, y); public int GetHashCode(T obj) => StructuralComparisons.StructuralEqualityComparer.GetHashCode(obj); } ``` I'm using the above when working with Roslyn's `ImmutableArray` and `ImmutableHashSet` and it is quite convenient. 18432 area-System.Collections ConcurrentDictionary throws for null comparer, unlike every other BCL API You would expect this to succeed: ```c# new ConcurrentDictionary((IEqualityComparer)null) ``` I'll quite often take advantage of the fact that all BCL APIs use `EqualityComparer.Default` when you pass null, and chain constructors and other methods with the parameter `IEqualityComparer comparer = null`.

This is causing other failures, see: 18437 area-System.Diagnostics [Netfx]: Bug in AsyncStreamReader.GetLinesFromStringBuilder() private API "When running the following code, we would get an `IndexOutOfRangeException` from `StringBuilder.get_Char(char)`. ```cs [Fact] public void TestAsyncHalfCharacterAtATime() { var receivedOutput = false; var collectedExceptions = new List(); Process p = CreateProcess(() => { var stdout = Console.OpenStandardOutput(); var bytes = new byte[] { 97, 0 }; //Encoding.Unicode.GetBytes(""a""); for (int i = 0; i != bytes.Length; ++i) { stdout.WriteByte(bytes[i]); stdout.Flush(); Thread.Sleep(100); } return SuccessExitCode; }); p.StartInfo.RedirectStandardOutput = true; p.StartInfo.StandardOutputEncoding = Encoding.Unicode; p.OutputDataReceived += (s, e) => { try { if (!receivedOutput) { Assert.Equal(e.Data, ""a""); } receivedOutput = true; } catch (Exception ex) { // This ensures that the exception in event handlers does not break // the whole unittest collectedExceptions.Add(ex); } }; p.Start(); p.BeginOutputReadLine(); Assert.True(p.WaitForExit(WaitInMS)); p.WaitForExit(); // This ensures async event handlers are finished processing. Assert.True(receivedOutput); } ``` When we call `p.BeginOutputReadLine()` it will call `AsyncStreamReader.ReadBuffer(IAsyncResult)` everything at this moment behaves as expected which has 1 char to read in the byte buffer (97). But when reading the chars through the decoder: https://referencesource.microsoft.com/#System/services/monitoring/system/diagnosticts/AsyncStreamReader.cs,192 We hit a bug in `UnicodeDecoder.GetChars` (see #18436) so we would get 0 as a result when reading the chars out of the decoder.

Also I moved `receivedOutput=true` to be updated before `Assert.Equal(e.Data, ""a"");` because if this Assert fails received output will never be set to true because the try catch will catch the xunit assert failure exception before updating the value. This will cause `Assert.True(receivedOutput);` to fail and the test will exit at that point causing ```cs if (collectedExceptions.Count > 0) { // Re-throw collected exceptions throw new AggregateException(collectedExceptions); } ``` To never be hitted so the real `Assert.Equal(e.Data, ""a"");` failure will never be thrown and the actual shown failure in the test execution will be `Assert.True(receivedOutput);` which would make it harder to debug as we did actually received output but not the expected. cc: @stephentoub @Priya91 @danmosemsft Contributes to #18262" 18439 area-System.Net Disable Private.Uri tests due to quirked behavior Fixes: #18314 Fixes: #18315 Fixes: #18316 I'm closing the above issues with this PR by disabling tests as this is already tracked by: #15145 cc: @davidsh @CIPop @danmosemsft 18441 area-System.Collections ConcurrentDictionary null comparer consistency with BCL Fixes #18432 Question: would it make sense to pass `null` instead of `EqualityComparer.Default` between the constructor overloads now? 1.

Don't construct new value for null operand, just push previous value back on stack. Conversely, don't store then load computed value, just leave it on the stack. Separate path for `Not` on `bool?` values now has no advantage, so roll into rest. Only two paths differ from others, so handle majority as default branch (previous default is unreachable and if not would result in same exception this way anyway). `TypeAs` is nop when result type is same as operand type, so do nothing.

I have some hot-path production code that looks like this. The queue is _usually empty_. `if(!myConcurrentQueue.IsEmpty) { WorkItem item; if(myConcurrentQueue.TryDequeue(out item)) { DoWork(item); } }` Clearly the assumption is that IsEmpty is a faster than calling TryDequeue. I decided to test this assumption with writing a little microbenchmark the compares IsEmpty versus TryDequeue on an empty queue.. I was surprised to find the IsEmpty appears to take about _twice a long_ as TryDequeue. Given that to dequeue anything there is probably a check to find out if there is anything in the queue, there's no reason I can think of for IsEmpty to be slower. 18467 area-System.Diagnostics Fix process product code and tests for netfx Fixes #18262 Fixes #18470 Fixes #18471 Fixes #18472 Fixes #18473 @safern 18468 area-System.Linq Remove some dead code in S.L.Expressions LambdaCompiler Contributes to #11409 by removing coverage gaps that can never be covered.

It is possible though. Upon compilation, if the `BindingType` is one of the values defined for the enum then both interpreter and compiler will throw an `InvalidCastException`. Otherwise the compiler will throw an `ArgumentException` while the interpreter will just ignore the binding. At the very least these should be consistent, but it seems more useful to throw the `ArgumentException` mentioned for one case above upon the call to `MemberBind` or `MemberInit` that the custom class was passed to. (Alternatively, making the constructor `internal` rather than `protected` would be better still, but a bigger change to the public API). 18495 area-System.Diagnostics DiagnosticSource: return packaging for UAP target UAP target was removed temporarily to build DiagnosticSource and publish it on nuget.org where UAP dependencies are missing (#18295).

This seems unnecessary because - Why not use `params object[]`? - Can't we make the method generic to avoid having to cast? ## Proposal ```cs namespace System.Reflection { public abstract partial class MethodBase : MemberInfo { // Existing API public object Invoke(object obj, object[] parameters); // Proposed API public TResult Invoke(object obj, params object[] parameters); } } ``` One other tiny pain point is that it seems kind of enigmatic to pass `null` as the first parameter to invoke a static method, so if the above looks OK we should add this API too: ```cs public TResult InvokeStatic(params object[] parameters); ``` ## Sample implementation ```cs public TResult Invoke(object obj, params object[] parameters) => (TResult)Invoke(obj, parameters); public TResult InvokeStatic(params object[] parameters) => Invoke(null, parameters); ``` ## Sample usage ```cs (bool)equalsMethod.Invoke(x, new object[] { y }) // becomes equalsMethod.Invoke(x, y) (int)compareMethod.Invoke(x, new object[] { y }) == 0 // becomes compareMethod.Invoke(x, y) == 0 ``` 18498 area-Infrastructure Re-enable package validation and clean up package content "Requires: https://github.com/dotnet/buildtools/pull/1441 This re-enables package validation and fixes all validation issues with packages.

I extracted those pieces and moved to [src/Common/src/System/Data/Common/](https://github.com/dotnet/corefx/tree/master/src/Common/src/System/Data/Common) (the folder where other common pieces for System.Data are located). We are trying to use corefx's System.Data in Mono where we have a single assembly System.Data.dll instead of 3 (Common, Odbc, SqlClient) so it's important for us to remove all duplicates (like I did in https://github.com/dotnet/corefx/pull/18297 and https://github.com/dotnet/corefx/pull/18281). A few notes: 1) Lots of members look unused anywhere - I didn't remove any of them, it's just an observation. 2) IsCatchableExceptionType and IsCatchableOrSecurityExceptionType look different and I am not sure which impl is the best (or they **should** be different): [Common](https://github.com/dotnet/corefx/blob/master/src/System.Data.Common/src/System/Data/Common/AdapterUtil.cs#L193-L225), [SqlClient](https://github.com/dotnet/corefx/blob/master/src/System.Data.SqlClient/src/System/Data/Common/AdapterUtil.cs#L264-L283), [Odbc](https://github.com/dotnet/corefx/blob/master/src/System.Data.Odbc/src/Common/System/Data/Common/AdapterUtil.cs#L222-L261).

You would expect this to succeed, but it throws `NullReferenceException`: ```c# ((IStructuralEquatable)(1, 2)).Equals((1, 2), null) ``` I'll quite often take advantage of the fact that all BCL APIs use `EqualityComparer.Default` when you pass null, and chain constructors and other methods with the parameter `IEqualityComparer comparer = null`. If my own constructor or extension method takes `IEqualityComparer comparer = null`, I assume that I can pass that into the BCL method. It's not intuitive to make it the call site's responsibility to check for null and pass `EqualityComparer.Default` *or* call one or the other BCL overload depending whether `comparer = null`. It's not critical since the workaround is to pass `comparer ?? EqualityComparer.Default` instead of `comparer`. This is an API gotcha that may go unnoticed until code is in the field though. [`ValueTuple<*>.IStructuralEquatable.Equals`][1] and [`ValueTuple<*>.IStructuralComparable.CompareTo`][2] have no null comparer check. If it followed the convention set by all other BCL methods, it would use `EqualityComparer.Default` if you pass null. [`Array.IStructuralEquatable.Equals`][3] and [`Array.IStructuralComparable.CompareTo`][4], and [`Tuple<*>.IStructuralEquatable.Equals`][5] and [`Tuple<*>.IStructuralComparable.CompareTo`][6] have the same problem.

This PR: - Ports desktop's IPv4AddressHelper and IPv6AddressHelper to core. I made as few changes as possible to these in order to get things to work, but I did make a few changes in order to fix some bugs, e.g. IPv6AddressHelper's validation routines were letting through some invalid addresses (e.g. nothing after a closing bracket was being validated, scope ID overflow wasn't being validated, etc.) - Replaces IPAddressPal.Unix.cs with IPAddressPal.Managed.cs. I left in place the current PAL layer, but in the future we could easily remove the PAL entirely and just use the managed implementation (I tried compiling IPAddressPal.Managed.cs into the Windows build, and it builds and tests fine. - The one place I did remove the PAL entirely was for IPAddressParser.IPv4AddressToString: there's no point in calling out to native code for that, so I put a managed implementation in place across the board. - I didn't spent a lot of time on performance, but I did remove some of the aggregious things that were happening, e.g. we were allocating a new StringBuilder every time we did IPAddress.ToString, we were allocating byte[]s while parsing unnecessarily, etc. - I consolidated some of the existing test cases into theories and added a bunch more test cases. This revealed other bugs on Unix, which I also addressed. cc: @geoffkizer, @Priya91, @davidsh, @CIPop, @pgavlin Fixes https://github.com/dotnet/corefx/issues/11843 (and some other bugs for which we don't have issues) 18557 area-System.Xml Fix XSLT test failures on Desktop Fixes Desktop failures in XslCompiledTransform and XslTransform test projects. cc: @danmosemsft @krwq FYI: @safern 18559 area-Serialization Old Serialization design is back but it needs refactoring. "The [Serializable] is back (I don't need it since I think it is as useless as a generic in-depth Clone method) but fine. Howerver, I have one major design concern. Current design forces us to store transient serialization data in the object itself. It is awful by design and, IMO, defeats the ""simple-safe-easy-to-use-principle"" of the API: - It is not obvious that storing this transient sate should be the way to go (even for beginners, it hurts). - Failing to set this state to null in OnDeserialization (or OnDeserialized ""event') will lead to memory leaks. This will happen for sure. - Understanding OnDeserialized event vs. IDeserializationCallback.OnDeserialization is... fun but not as much as the SafeSerializationManager... Since I understand the "".Net Framework API surface compatibility"" goal, I think we (the .Net community at large) are missing here a great opportunity to fix what is clearly a bad design option. Is there any issue with the following approach? 1 - Offer a way to the deserialization ctor to store a transient state object. - Thanks to a new SetDeserialiazationState method on the StreamingContext? - Ouch! it's a struct that cannot be changed/extended... let's handle another deserialization ctor with an enhanced StreamingContext or one new parameter. 2 - Give back this object to the OnDeserialization method. - Thanks to a new IDeserializationStateCallback may be? - And, may be also, the OnDeserialized event could allow a new ""object state"" in its signature (since this one is more ""duck typed"". The ObjectManager should be able to manage this transient state correctly. Am I missing something here? I think so... SafeSerialization introduce other complexities. And the attribute/event approach is better than the potentially virtual OnDeserialization method. Again, am I missing something here? Are there hidden/secret plans to handle this more correctly? I guess I'm not the only one that feel a little bit sad to see those stuff coming back into the clean .Net Core code base...

This has been fine in the Windows world since it's not used but it is used by Unix's zip/unzip programs to store file permissions of an entry. As it currently stands, there is no way to carry Unix RWX permissions within a zip, so at unzip time the unzipper has to guess at permissions and manually chmod the entries. This PR simply exposes the raw field so that it may be used in any circumstance that requires access to the field. Tests are added to ensure that this field is set, read, and roundtrips properly with zips created from other common programs which use the field. Note: Unix `unzip` doesn't apply permissions in the external file attributes field of a zip produced on Windows. So if you modify the externalfileattributes of a zip on Windows, `unzip` will use the defaults instead of what is set in the field. This isn't easily resolvable on our side since the platformmadeby byte determines a number of other things that we don't want to mess with (e.g. file name validity), so it would be unwise to lie about the platform on which the zip was written. resolves https://github.com/dotnet/corefx/issues/17067 cc: @eerhardt @danmosemsft @stephentoub 18567 area-Infrastructure Add .NET Framework 4.7 support to NETStandard.Library.NETFramework package We need a separate build of both ref (shims.proj so that it unifies with ValueTuple in mscorlib) and lib to support net47.

The tests would randomly fail because of the way that port allocation is different than on Windows. On Linux\Mac, when asking for an available free port, the returned port number is a random unused port. On Windows, it is incremental and eventually rolls over. These tests are negative tests that connect to a V4 port and then send\listen on a V6 port (or vise-versa) of the same number expecting an unused port and thus failure case. However, in Linux\Mac there is a chance that the port is active instead of unused, causing the test to succeed, and\or interfering with a 'good' test. The port may be active on Windows too, causing similar problems, but the odds are much less as any given test run should not have active ports open that longs. Two options to re-enable these tests: 1) Enable a test mode where a given test is flagged an runs serially 2) Move the tests to a new assembly with the CollectionBehavior attribute (DisableTestParallelization=true, MaxParallelThreads=1) For these to work, all other tests should be done running, including tests in other assemblies (at least those tests which use sockets). An alternative way to re-enable these tests is to keep them in the current assembly, but change the logic to something like this to preserve the original intent of making sure the socket is isn't 'dual mode': 1) Bind to address family with port 0 so we get unused port 2) Bind to the other address family + same port 3) The bind should succeed (otherwise retry by going back to step 1) 4) Unbind (so we can do the receive on it) 5) Do the actual receive on that unbound port 6) Should fail (as these tests are negative tests) This alternative approach will increase reliability but there is a small chance between 4 and 5 another test grabbed that port. However, if 3 succeeds then it probably proves that the socket wasn't dual mode because you can't bind to the same port + family twice; thus perhaps the test can stop there and not include 4-6.

Rationale and Usage ------------------------------------- Given a `Key` it will return the associated `Value` if the `Key` already exists in the table, otherwise it will add an entry with the `Key, Value` to the table. As @stephentoub pointed out today we can achieve this with `cwt.GetValue(key, _ => value);`. However, that is inefficient as it creates a delegate and closure. For an example, we have used the internal implementation [here ](https://github.com/dotnet/corert/blob/4d6760f3ca6ca17eb31c441bc5d8f5c1e309386c/src/System.Private.CoreLib/src/System/Runtime/InteropServices/PInvokeMarshal.cs#L254) to add items to the delegate marshalling table which is implemented using `ConditionalWeakTable`. Proposed API --------------------------- ```c# public sealed class ConditionalWeakTable : IEnumerable> where TKey : class where TValue : class { // Existing public ConditionalWeakTable(); ~ConditionalWeakTable(); public bool TryGetValue(TKey key, out TValue value); public void Add(TKey key, TValue value); public void AddOrUpdate(TKey key, TValue value); public bool Remove(TKey key); public void Clear(); public TValue GetValue(TKey key, CreateValueCallback createValueCallback); public TValue GetOrCreateValue(TKey key); public delegate TValue CreateValueCallback(TKey key); //Proposed public TValue GetValue(TKey key, TValue value); } ``` Implementation ------------------------ I have checked-in an internal implementation of the API [here](https://github.com/dotnet/corert/blob/4d6760f3ca6ca17eb31c441bc5d8f5c1e309386c/src/System.Private.CoreLib/src/System/Runtime/CompilerServices/ConditionalWeakTable.cs#L431). 18583 area-Infrastructure Update netfx and netcoreapp baseline files For netfx baseline files we are no including netstandard ref folder in the list of resolve paths to find assemblies for netfx. cc @ericstj 18584 area-System.Runtime Reenable Array.CreateInstance Tests for UapAot in System.Runtime.Tests.dll.

This distro is not supported officially, and we are no longer running any official builds on it. Closes https://github.com/dotnet/corefx/issues/18029. 18589 area-System.Linq Proposal: Enumerable.RemoveAll(T) and RemoveFirst(T) ## Background Most of the time I use `Enumerable.Except`, I only want to remove one item. Unfortunately, `Except` takes an `IEnumerable` so I have to write `new[] { }` every time. Here are a couple of instances where this has happened recently: - [Polynomial.cs](https://gitlab.com/jamesqo/PolynomialReducer/blob/master/PolynomialReducer/CompactR/Polynomial.cs#L330) - [Data.cs](https://gitlab.com/jamesqo/PolynomialReducer/blob/master/PolynomialReducer.Tests/CompactR/Data.cs#L19) - [ImmutableArrayTest.cs](https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/tests/ImmutableArrayTest.cs#L1935) ## Proposal - I suggest we add a new method to `Enumerable`, `RemoveAll`, that takes a single item to remove from the user. **edit:** This method will return a new enumerable with all occurrences of the item removed, or an equivalent enumerable if the item wasn't found. - A `RemoveFirst` method will also be added for symmetry; it will remove the first occurrence of a specified item in the enumerable, or return an equivalent enumerable if the item wasn't found. ```cs namespace System.Linq { public static class Enumerable { public static IEnumerable RemoveAll(this IEnumerable source, TSource element); public static IEnumerable RemoveAll(this IEnumerable source, TSource element, IEqualityComparer comparer); public static IEnumerable RemoveFirst(this IEnumerable source, TSource element); public static IEnumerable RemoveFirst(this IEnumerable source, TSource element, IEqualityComparer comparer); } } ``` Does this sound like a reasonable idea? /cc @JonHanna **edit:** There would be one big semantic difference from `Except(new[] { item })`: the enumerable returned would not necessarily be distinct. For example, `new[] { 2, 3, 3 }.Except(new[] { 2 })` is `[3]`, while `new[] { 2, 3, 3 }.Remove(2)` would be `[3, 3]`. (I didn't even realize `Except` returned distinct items until I looked at its source code a second ago.) 18590 area-System.Net "HttpRequestStreamTests.Read_FullLengthAsynchronous_Success failed in CI with ""invalid response""" "https://ci.dot.net/job/dotnet_corefx/job/master/job/windows_nt_debug_prtest/6549/consoleText ``` Test: ExecuteReaderWithCommandBehaviorTest Enabled Listeners System.Net.Tests.HttpRequestStreamTests.Read_FullLengthAsynchronous_Success(transferEncodingChunked: True, text: \""\"") [FAIL] System.Net.Http.HttpRequestException : An error occurred while sending the request. ---- System.Net.Http.WinHttpException : The server returned an invalid or unrecognized response Stack Trace: at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult() D:\j\workspace\windows_nt_de---4526f5ff\src\System.Net.Http\src\System\Net\Http\HttpClient.cs(462,0): at System.Net.Http.HttpClient.d__58.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() D:\j\workspace\windows_nt_de---4526f5ff\src\System.Net.HttpListener\tests\HttpRequestStreamTests.cs(72,0): at System.Net.Tests.HttpRequestStreamTests.d__5.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() Test: ExecuteReaderWithCommandBehaviorTest Started Server at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) ----- Inner Stack Trace ----- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() D:\j\workspace\windows_nt_de---4526f5ff\src\Common\src\System\Threading\Tasks\RendezvousAwaitable.cs(62,0): at System.Threading.Tasks.RendezvousAwaitable`1.GetResult() D:\j\workspace\windows_nt_de---4526f5ff\src\System.Net.Http.WinHttpHandler\src\System\Net\Http\WinHttpHandler.cs(863,0): at System.Net.Http.WinHttpHandler.d__105.MoveNext() Test: ExecuteReaderWithCommandBehaviorTest SqlOperation Successful Test: ExecuteReaderWithCommandBehaviorTest Listeners Disabled Test: ExecuteReaderWithCommandBehaviorTest Server Disposed Test: ExecuteReaderWithCommandBehaviorTest Listeners Disposed Successfully Test: ConnectionOpenAsyncErrorTest Enabled Listeners Finished: System.Net.HttpListener.Tests ```" 18591 area-System.Net Fix IPAddress parsing tests for netfx Some have an InnerException, some don't.

If `src` and `dst` do not overlap and the GC swaps the order of `src` and `dst` in the address space between the two checks, then `isOverlapped` becomes erroneously `true`: ```csharp int srcLength = 50; int dstLength = 50; T[] array = new T[300]; ref T src1 = ref array[0]; // src before swap ref T dst = ref array[100]; IntPtr srcMinusDst = Unsafe.ByteOffset(ref dst, ref src1); bool srcGreaterThanDst = (sizeof(IntPtr) == sizeof(int)) ? srcMinusDst.ToInt32() >= 0 : srcMinusDst.ToInt64() >= 0; IntPtr tailDiff; ref T src2 = ref array[200]; // src after swap if (srcGreaterThanDst) { // If the start of source is greater than the start of destination, then we need to calculate // the different between the end of destination relative to the start of source. tailDiff = Unsafe.ByteOffset(ref Unsafe.Add(ref dst, dstLength), ref src2); } else { // If the start of source is less than the start of destination, then we need to calculate // the different between the end of source relative to the start of destunation. tailDiff = Unsafe.ByteOffset(ref Unsafe.Add(ref src2, srcLength), ref dst); } // If the source is entirely before or entirely after the destination and the type inside the span is not // itself a reference type or containing reference types, then we can do a simple block copy of the data. bool isOverlapped = (sizeof(IntPtr) == sizeof(int)) ? tailDiff.ToInt32() < 0 : tailDiff.ToInt64() < 0; Debug.Assert(!isOverlapped); ``` It's not really a bug, because the subsequent copy operation is just less optimized. But it's a bit surprising, and may not be obvious to people looking at the code, who could assume that the overlap check gives correct results under all circumstances. cc @jkotas (related: https://github.com/dotnet/corefx/issues/17793) 18609 area-System.Threading Expose Task.IsCompletedSuccessfully Fixes https://github.com/dotnet/corefx/issues/16745 cc: @kouvel, @alexperovich 18610 area-System.Linq Prohibit Expression.Bind with members of open generic types.

This addresses reentrancy issue occurring on CLR shutdown described in https://github.com/dotnet/corefx/issues/18632 and makes the Dispose method thread safe. Hardens all finalizers against thread abort and race conditions. Fixes https://github.com/dotnet/corefx/issues/18632 (internal bug 360526) 18632 area-System.Reflection Reentrancy in AbstractMemoryBlock.Dispose on shutdown "Copied from internal VSO bug 360526. **Crash Analysis** In the crash case, the portable PDB reader ends up running because CLR shutdown has already been kicked off on another thread, meaning clr!g_fEEShutDown has been transitioned to a nonzero value. Once this happens, the code that would normally acquire an ISymUnmanagedReader for mscorlib/System.Web short circuits at the following stack: ``` // // if (g_fEEShutDown) // RETURN NULL; // clr!Module::GetISymUnmanagedReader clr!Module::GetISymUnmanagedReaderNoThrow clr!DebugStackTrace::GetStackFramesInternal mscorlib!System.Diagnostics.StackFrameHelper::InitializeSourceInfo ``` Once the short-circuit occurs, control unwinds back to GetStackFramesInternal and enters the blocks that ""fall back"" to portable PDB probing in cases where the required source info can't be obtained from a legacy PDB. In other words, the portable PDB reader ""light up everywhere"" once the CLR enters shutdown. Details on how the portable PDB code ended up crashing The reported crash occurred during the execution of the NativeHeapMemoryBlock finalizer (on the finalizer thread): ``` KERNELBASE!LocalFree+0x2e mscorlib_ni!DomainNeutralILStubClass.IL_STUB_PInvoke(IntPtr)+0x6e mscorlib_ni!System.Runtime.InteropServices.Marshal.FreeHGlobal(IntPtr)+0x22 System_Core_ni!System.Reflection.Internal.NativeHeapMemoryBlock.Dispose(Boolean)+0x11 System_Core_ni!System.Reflection.Internal.NativeHeapMemoryBlock.Finalize()+0x1a clr!FastCallFinalizeWorker+0x6 clr!FastCallFinalize+0x55 ``` The crash occurred during while CLR shutdown was underway, and specifically happened during the ""Shutdown_Finalize2"" pass of shutdown finalization. This pass has the following properties: Before the pass starts, the runtime is ""mostly suspended"" such that only the finalizer thread is allowed to run managed code (i.e., all other managed threads have been forced out of managed code via the same mechanism that is used during GC suspension). The pass finalizes ALL finalizable objects on the GC heap, regardless of whether the objects are ""live"" or ""dead"". In the crash case, step 1 occurred while a thread was in the middle of the Dispose code for the very same NativeHeapMemoryBlock instance. The runtime ""trapped"" this thread when it tried to return back to managed code, meaning it was sitting at the following stack at crash time: ``` clr!JIT_RareDisableHelper+0x14 mscorlib_ni!DomainNeutralILStubClass.IL_STUB_PInvoke(IntPtr)+0x87 mscorlib_ni!System.Runtime.InteropServices.Marshal.FreeHGlobal(IntPtr)+0x22 System_Core_ni!System.Reflection.Internal.NativeHeapMemoryBlock.Dispose(Boolean)+0x11 System_Core_ni!System.Reflection.Internal.AbstractMemoryBlock.Dispose()+0x19 System_Core_ni!System.Reflection.PortableExecutable.PEReader.ReadDebugDirectory()+0x21c ``` So in this case (which can only happen when finalizing ""live"" objects during shutdown finalization), while the finalizer doesn't literally ""race"" with the Dispose code, it does conceptually end up ""preempting"" it. As a result, it ends up running the following line twice (from fx\src\Core\System\Reflection\Internal\MemoryBlocks\NativeHeapMemoryBlock.cs): ``` Marshal.FreeHGlobal((IntPtr)_pointer); ``` This generates a double-free, which generates the heap corruption that was detected by the IIS stress harness." 18635 area-System.IO Fix several System.IO.Packaging issues with differing desktop behavior On desktop, calling Package.Open(stream, FileMode.Create, ...) on a seekable stream sets the length to 0, since the ZipArchive that gets created from it will seek around in the stream and considers it to start from position 0 rather than the current position. The core implementation was not doing that. Then tests were written against core; those tests should have used FileMode.Open but used FileMode.Create (presumably by accident), and thus on desktop the stream was being cleared whereas on core it was not. This change fixes the core implementation to do the same stream validation/mutation that's done on desktop (additional code a direct copy of what's in desktop), and updates the tests to use FileMode.Open instead of FileMode.Create in the few problematic cases. I then added a couple of additional tests.

In `netcoreapp1.1`, `HttpClient` automatically sends header `""Accept-Encoding"": ""gzip, deflate""` in the request, and automatically decompress 'gzip/deflate' content from the response. However, with `netcoreapp2.0`, `HttpClient` doesn't send the header and stop automatically decompressing 'gzip/deflate' content.

You can see `Accept-Encoding` was sent by `HttpClient`. `http://httpbin.org/gzip` returns gzip-encoded data. You can see the content was automatically decompressed by `HttpClient`. ``` PS> dotnet restore PS> dotnet run Header Dict: { ""headers"": { ""Accept-Encoding"": ""gzip, deflate"", ""Connection"": ""close"", ""Host"": ""httpbin.org"" } } Decompressed Content: { ""gzipped"": true, ""headers"": { ""Accept-Encoding"": ""gzip, deflate"", ""Connection"": ""close"", ""Host"": ""httpbin.org"" }, ""method"": ""GET"", ""origin"": ""131.107.147.177"" } ``` **With netcoreapp2.0** `Accept-Encoding` was not sent by `HttpClient` and the gzip-encoded data was not automatically decompressed. ``` PS> dotnet restore PS> dotnet run Header Dict: { ""headers"": { ""Connection"": ""close"", ""Host"": ""httpbin.org"" } } Decompressed Content:  W??X?%?A ?0E?9E??? nE? ^??C2????K??]??????r?.V?O?????*[5*?rJ8 qR?+?>???U?""?E?q ??v?>(?????.h7??;???????? ``` Environment --------------- **netcoreapp1.1** ``` .NET Command Line Tools (1.0.1) Product Information: Version: 1.0.1 Commit SHA-1 hash: 005db40cd1 Runtime Environment: OS Name: Windows OS Version: 10.0.14393 OS Platform: Windows RID: win10-x64 Base Path: ...\AppData\Local\Microsoft\dotnet\sdk\1.0.1 ``` **netcoreapp2.0** ``` .NET Command Line Tools (2.0.0-preview1-005724) Product Information: Version: 2.0.0-preview1-005724 Commit SHA-1 hash: e391b5d5f3 Runtime Environment: OS Name: Windows OS Version: 10.0.14393 OS Platform: Windows RID: win10-x64 Base Path: ...\AppData\Local\Microsoft\dotnet\sdk\2.0.0-preview1-005724\ ```" 18647 area-System.IO CrossCompilation IsolatedStorage Fixes #18578 18649 area-System.Drawing Does the upcoming .net core 2.0 support System.Drawing fully in Linux? 18650 area-System.Security Validate the DER components of user-provided data The parameters value for the PublicKey and the generator's SignatureAlgorithm both are supposed to be DER-encoded; so validate that claim.

In the version 4.0.10.0 the System.Net.Requests.dll did implement the HttpWebRequest.AllowReadStreamBuffering and allowed it to be set to true (and it actually did make a difference in behavior). In the latest code, the property always returns false, and can't be set to true. It throws InvalidOperationException if something tries to set it to true. This obviously breaks backward compatibility. 18669 area-System.Net Fix recently added KeepAlive test on desktop "The WinHTTP implementation sends Connection: ""keep-alive"", the desktop implementation does not. Just change the test to validate whether Connection: ""close"" is sent or not. Fixes https://github.com/dotnet/corefx/issues/18657" 18672 area-System.Net Fix/disable several System.Net.Security tests on desktop - SslStream_StreamToStream_WriteAsync_ReadAsync_Pending_Success was hanging / timing out on desktop because it relied on Read/WriteAsync not going through the base Stream's Read/WriteAsync, which serializes the delegated calls to Begin/EndRead/Write. Desktop's implementation calls directly to Begin/EndRead/Write whereas in core (by design) we call Read/WriteAsync (which will in turn use Begin/EndRead/Write if the Async method wasn't overridden), but the VirtualNetworkStream wasn't overriding Begin/EndReadWrite to avoid the serialization, and since the test requires non-serialization, it hung. - SslStream_StreamToStream_FlushAsync_Propagated and NegotiateStream_StreamToStream_FlushAsync_Propagated both rely on FlushAsync being overridden, which it's not in desktop. - NegotiateStream_StreamToStream_Authentication_EmptyCredentials_Fails fails due to a known behavioral difference from desktop for which there's already an open issue.

They do so with fakes that intercept the calls. But on desktop, the real methods were being used, bypassing that interception. I've fixed it by making the unit tests on desktop compile like core so as to use the fakes. Fixes https://github.com/dotnet/corefx/issues/18656 cc: @cipop, @davidsh, @Priya91 18674 area-System.Net WebClient.UploadValuesAsync app-compat difference with Desktop "While investigating #17882, I root caused the failure of the WebClient.UploadValuesAsync test. On .NET Framework, WebClient uses an internal method, `UrlEncodeBytesToBytesInternal`, to ""UrlEncode"" the NameValueCollection. This is causing it to use lowercase hex digits. On .NET Core, WebClient uses the public WebUtility.UrlEncode method which always uses uppercase hex digits. The public WebUtility.UrlEncode is behaving the same (uppercase digits) on both .NET Framework and .NET Core.

Issue tracking the problem: https://github.com/dotnet/corefx/issues/15136 cc: @safern 18680 area-System.Net Validation missing when adding certain headers to WebClient.Headers collection While investigating #17882, I discovered that adding certain request headers to `WebClient` are not error-checked the same between .NET Core and .NET Framework implementations. Adding 'Connection', or 'Expect' request headers throws WebException when sending the request using .NET Framework. But .NET Core does not throw exception. Adding 'Host' request header with an illegal DNS name throws WebException when sending the request using .NET Framework. But .NET Core does not throw exception. Added new tests to validate this and marked the tests as disabled for .NET Core. 18681 area-System.Net Root cause WebClient test failures on NETFX Finished investigation of failures on .NET Framework for WebClient.

My previous fix was overly aggressive in changing from IOException to OperationCanceledException (I must have been running the tests incorrectly or something). Specifically, desktop handles unexpected cancellation for some operations differently than it does for others: for most operations it always uses an OperationCanceledException, but for WaitForConnectionAsync, it uses IOException.

This resulted in having the property throw an exception when set to true. That behavior is what .NET Framework currently does. Historically, this property did not always exist in .NET Framework at all. Other portable versions of .NET (Windows Phone, Silverlight) for the HTTP stack were implemented differently and had this property which worked. When .NET Framework APIs were reconciled in 2015, this virtual property was added to .NET Framework but the functionality on Desktop was limited.

That member call returns a `DirectoryInfo` object but doesn't tell you, whether it already existed or was just created. In scenarios where you want to execute code only if the directory was just created, you have to add extra code. ### Proposal ```C# namespace System.IO { public static partial class Directory { // Existing API: // public DirectoryInfo CreateDirectory(string path); public DirectoryInfo CreateDirectory(string path, out bool created); } } ``` ### Usage ```C# System.IO.Directory.CreateDirectory("""", out bool created); if (created) { // Some code which should only be executed if the directory was created } ``` I came up with this proposal while working in System.IO.IsolatedStorage for https://github.com/dotnet/corefx/pull/18647#discussion_r112710798 ### Alternatives Calling `Directory.Exists(string)` first: ``` c# bool alreadyExisted = Directory.Exists(path); DirectoryInfo info = Directory.CreateDirectory(path); if (!alreadyExisted) { // Some code which should only be executed if the directory was created } ``` This is problematic as between `Directory.Exists(string)` and `Directory.CreateDirectory(string)` a race condition could happen like the state of the directory has changed (e.g. deleted). /cc @terrajobst @JeremyKuhne " 18750 area-System.Memory API Proposal: Span - find if one span contains another; perhaps IsSliceOf "From https://github.com/dotnet/corefxlab/issues/827 by @mgravell A scenario I find myself needing is to see whether one span is a sub-span of another. This test is semantically valid for both array and pointer spans, and is a related operation to `Slice` Suggested API: ``` Span bool IsSliceOf(Span span); bool IsSliceOf(Span span, out int offset); ``` where it is: - `true` if both spans are array-based, for the exact same array, where the inner offet >= outer offset, and inner offset+count <= outer offset+count - `true` if both spans are pointer-based, and inner ptr >= outer ptr and inner ptr+count <= outer ptr+count - `false` otherwise or could be unified to: ``` int GetSliceIndex(Span span) ``` (returns -1 if not a slice; kinda ugly) Would be happy to contribute towards the code, but wanted to discuss API first. https://github.com/dotnet/corefxlab/issues/827#issuecomment-296100325: > The specific example was trying to find the parent block that owns a range (one of several known blocks) so we can do a slice and dice - however, it occurs that the moment I say ""one of several"" it is clear that we aren't talking just about stack-based spans, so all of this could work just as well against Buffer-T if that would be preferable.

While the root cause for that is for another issue, it generated quite interesting scenario that I decided to extract. Consider following reproducable case: ```c# using System; using System.Diagnostics.CodeAnalysis; using System.Threading; using System.Threading.Tasks; namespace test { internal static class Program { private static readonly ManualResetEventSlim ShutdownEvent = new ManualResetEventSlim(false); private static void Main() { AppDomain.CurrentDomain.UnhandledException += OnUnhandledException; TaskScheduler.UnobservedTaskException += OnUnobservedTaskException; Console.WriteLine(""Start""); Reproduce().Forget(); Console.WriteLine(""Forget""); ShutdownEvent.Wait(); Console.WriteLine(""End""); } private static async Task Reproduce() { Console.WriteLine(""Start inner""); await GetNullTask().ConfigureAwait(false); Console.WriteLine(""Set event""); ShutdownEvent.Set(); Console.WriteLine(""End inner""); } private static Task GetNullTask() { return null; } private static void Forget(this object obj) { } private static void OnUnhandledException(object sender, UnhandledExceptionEventArgs e) { Console.WriteLine(""OnUnhandledException!""); } private static void OnUnobservedTaskException(object sender, UnobservedTaskExceptionEventArgs e) { Console.WriteLine(""OnUnobservedTaskException!""); } } } ``` As you can see, `await GetNullTask().ConfigureAwait(false);` is trying to await a `Task` that is null. Thing is, nothing is happening, the function is entirely frozen - no unhandled exception being raised, no unobserved task exception being raised (which should happen), and no function returning - limbo. ``` root@debian:~/test/test# dotnet exec bin/test.dll Start Start inner Forget ``` I'm pretty sure this is **really** unwanted - I didn't test if the same behaviour exists in .NET core 1.1, but regardless if it does, I think this should be corrected with proper (unobserved task) exception being raised. Otherwise there is no way to even guess that some problem occured, and unobserved task exception event is the function that should catch situation like that. Of course there is no issue if we replace `Reproduce().Forget()` with `Reproduce.Wait()`: ``` Unhandled Exception: System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) ---> System.NullReferenceException: Object reference not set to an instance of an object. at test.Program.d__2.MoveNext() --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at System.Threading.Tasks.Task.Wait() at test.Program.Main() ``` But in `Forget()` case, there should still be `TaskScheduler.UnobservedTaskException` being raised. ``` .NET Command Line Tools (2.0.0-preview1-005825) Product Information: Version: 2.0.0-preview1-005825 Commit SHA-1 hash: b4a821109d Runtime Environment: OS Name: debian OS Version: 9 OS Platform: Linux RID: ubuntu.16.10-x64 Base Path: /opt/dotnet/sdk/2.0.0-preview1-005825/ Microsoft .NET Core Shared Framework Host Version : 2.0.0-preview1-002028-00 Build : 6d0caecf154d3398b9bc0e637089b6af9e250479 ```" 18756 area-System.Diagnostics Expose ulong value for ProcessThread.Id With .NET Core being cross-plat supporting OSX, Linux and Windows, we have to provide accurate APIs that reflect the behavior of underlying OS design. On OSX, the Id of threads is 64 bit unsigned value, whereas in .NET core, the exposed ProcessThread.Id returns int, hence we truncate the ulong to int by casting, resulting in data loss and incorrect values on OSX. ```c# namespace System.Diagnostics { public partial class ProcessThread : System.ComponentModel.Component { public ulong RawId { get { throw null; } } } } ``` 18758 area-System.Diagnostics Handle thread ids overflow on OSX. cc @danmosemsft @karelz fixes #17187 filed #18756 to track addressing the use of large ulong values for thread id being hit frequently in osx 10.12 update. 18759 area-System.IO Add SafeFileHandle access for IStorageFolder and IStorageFile With the Windows 10 Anniversary Update interfaces were added to `IStorageFolder` and `IStorageFile` to create a standard Win32 file handle. ([`IStorageFolderHandleAccess`](https://msdn.microsoft.com/en-us/library/mt765061(v=vs.85).aspx) and [`IStorageItemHandleAccess`](https://msdn.microsoft.com/en-us/library/mt765064(v=vs.85).aspx)) We should expose wrappers for the `Create` methods on these interfaces. (Note that you explicitly have to request these through `IUnknown`) ## Rationale and Usage Getting the Win32 handle allows richer interop with both .NET and other existing libraries. You can, for example, go straight to a .NET `FileStream` without complicated and potentially performance-sapping wrappers. Exposing these methods is also a direct request from the Windows team. Usage example: ``` C# public void Foo(IStorageFile storageFile) { SafeFileHandle handle = storageFile.CreateSafeFileHandle(FileAccess.Read); using (FileStream stream = new FileStream(handle, FileAccess.Read)) { ... } } ``` ## Proposed API We already have IO extension methods in [`System.IO.WindowsRuntimeStorageExtensions`](https://msdn.microsoft.com/en-us/library/system.io.windowsruntimestorageextensions(v=vs.110).aspx) (in `System.Runtime.WindowsRuntime.dll`). These would be added there. ``` C# public static class WindowsRuntimeStorageExtensions { public static SafeFileHandle CreateSafeFileHandle( this IStorageFile windowsRuntimeFile, FileAccess access = FileAccess.ReadWrite, FileShare share = FileShare.Read, FileOptions options = FileOptions.None) { ... } public static SafeFileHandle CreateSafeFileHandle( this IStorageFolder rootDirectory, string relativePath, FileMode mode) { return rootDirectory.CreateSafeFileHandle(relativePath, mode, (mode == FileMode.Append ? FileAccess.Write : FileAccess.ReadWrite)); } public static SafeFileHandle CreateSafeFileHandle( this IStorageFolder rootDirectory, string relativePath, FileMode mode, FileAccess access, FileShare share = FileShare.Read, FileOptions options = FileOptions.None) { ... } } ``` ## Parameter Naming and Defaults Parameters follow naming used in existing methods in `WindowsRuntimeStorageExtensions` and `FileStream`. `FileStream` defaults for constructors are the defaults here as well. ## Parameter Validation | Exception | Case | |---|---| | ArgumentNullException | Thrown if `relativePath` is null | | NotSupportedException | Thrown for `FileShare.Inheritable` and `FileOptions.Encrypted` | | ArgumentOutOfRangeException | Thrown for any other undefined enum values | Note that we explicitly allow `(FileOptions)0x20000000` (which is `NoBuffering`) as FileStream does. We will not do other validation of incompatible combinations of enum values- we'll allow Windows to do this and surface whatever errors it returns. ## Error Handling If the cast to `IStorageFolderHandleAccess` or `IStorageItemHandleAccess` fails for any reason we'll return null. Failed HRESULTs returned from the methods will be converted into normal System.IO exceptions. (As [GetExceptionForWin32Error](http://source.dot.net/#System.Private.CoreLib/shared/System/IO/Win32Marshal.cs,8cf456a56c1e487e,references) would.) ## Other Notes We will not support oplocks or `IOplockBreakingHandler`. We don't support oplocks elsewhere- any such support here should come in with general oplock support. ## Future Considerations We should investigate converting the various `WindowsRuntimeStorageExtensions.OpenStreamFor*Async` extension methods to directly creating a FileStream via these new interfaces if possible. Adding additional non `Async` wraps should be considered as well. 18760 area-Infrastructure UWP ILC runs should run in appcontainer We get some coverage from UWP CoreCLR runs but some cases have emerged where API in the ILC context needs an app identity.

However there is a valid production scenario when there are two listeners in the application that want different set of events: e.g. ApplicationInsights for the 'new' events and Glimpse for the 'old' events. With mutual exclusiveness, only 'new' listener will receive any events. Besides Glimpse, VisualStudio consumes 'old' events, however I do not know whether it is internal logging or listener is somehow injected into the application where other listeners may exist; may be @nbilling can provide more details on it. Potentially there are other consumers affected by this change. Simple solution would be to check for deprecated event listener with IsEnabled method even if there was a listener to new event, however the assumption is that frequently there will be just one listener. IsEnabled for deprecated events may be cached under the assumption that there are no consumers that dynamically subscribe and unsubscribe. /cc @vancem @avanderhoorn @nbilling @cwe1ss 18763 area-System.Globalization System.Globalization Area Performance Tests "This is a tracking issue describing the current performance tests we have in the System.Globalization area, and what coverage is missing.

These two rules are a discovered state of Windows chain validation after cross-reading RFC 3280, RFC 5280 and ITU-T X.509 2012/10. The ""self-signed"" portion turns out to be difficult, since both Windows and OpenSSL take the AuthorityKeyIdentifier extension into account. It's even more difficult in that they don't seem to take them into account in the same way. So the existing two IsSelfSigned methods are deleted, and replaced with a new one that takes the KeyId form of AKID into account, because they treat that form the same. We can be confused by the signature not working out, but that just means we accept certs for signing that the chain builders reject.

This causes code like this: ```c# FileWebResponse response = ... Assert.Equal(data.Length.ToString(), response.Headers[HttpResponseHeader.ContentLength]); ``` to pass on .NET Core (which is wrong). Instead, it should throw an exception >System.InvalidOperationException : This collection holds request headers and cannot contain the specified response header. similar to what happens on .NET Framework. The exception is because FtpWebResponse/FileWebResponse don't have Http type headers. So, the net result is that we don't have proper validation for WebHeaderCollection type. The problem is that on .NET Core, the `WebHeaderCollection` is being created with the default contructor which doesn't pass it any specific `WebHeaderCollectionType` enum value. On .NET Framework, it uses an internal constructor overload. Also, the `WebHeaderCollectionType` enum is also marked as internal in .NET Framework and is not a public API. This was ok for .NET Framework since everything was in System.dll. But on .NET Core, WebHeaderCollection lives in a different library from System.Net.Requests where *WebRequest, *WebResponse classes live. ```c# internal enum WebHeaderCollectionType : ushort { Unknown, WebRequest, WebResponse, HttpWebRequest, HttpWebResponse, HttpListenerRequest, HttpListenerResponse, FtpWebRequest, FtpWebResponse, FileWebRequest, FileWebResponse, } internal WebHeaderCollection(WebHeaderCollectionType type) : base(DBNull.Value); ``` This is resulting in all WebHeaderCollection objects being set with the `WebHeaderCollectionType.Unknown` enum value. 18786 area-System.Diagnostics Activity: Proposal for an easier/more flexible tracer contract "Since I can't stop thinking about this topic ([see initial discussion](https://github.com/dotnet/corefx/issues/16491)), I'd like to show you a proposal for a IMO more usable Activity system that tries to be a compromise between OpenTracing and what Activity does right now. /alphabetical cc with people I've seen on related issues: @avanderhoorn @benaadams @Dmitry-Matveev @lmolkova @nbilling @SergeyKanzhelev @vancem Main differences/concepts: * It uses a **separate static `Tracer` class and an `ITracer` interface** instead of DiagnosticSource. * I know that it would be nice to reuse something existing but DiagnosticSource is not useful for Activities IMO because: * The Start/Stop events are defined by string values. Everyone could raise an ""activity""-like event that ends with "".Stop"" and tracers would have no good way to differentiate them from real activity events. * There's currently no easy/reliable way to get *all* started/stopped activities. Tracers have to rely on `EndsWith("".Stop"")`-code to subscribe to all activity events. * It doesn't allow you to pass additional arguments without creating anonymous objects. I'd like to always pass the actual activity instance because accessing Activity.Current in a tracer is not reliable enough IMO - especially together with the previous points (does it also have worse performance???). * It is not extensible. We need Inject/Extract hooks to be compatible with 3rd party tracers. With DiagnosticSource, this would result in even more strange string-based events with weird arguments. * In contrast to my [opentracing-code](https://github.com/opentracing/opentracing-csharp), the proposed static `Tracer` does not rely on DependencyInjection and can easily be used everywhere. * It is also zero-allocation based if tracing is off (at least I think so) * There are **hooks for Inject/Extract of IDs and baggage** to support existing tracers. This is an absolute must-have IMO because otherwise this whole system is useless for everyone but new tracers. * The currently used http standard is completely proprietary and not used by anyone. Something like this shouldn't be hard-coded in such a deep layer of the .net framework. * Since there have been concerns about the complexity of inject/extract in opentracing, the proposed code might be a possible compromise (with advantages and disadvantages of course). This would have to be discussed. * I propose to **always set default tags**! Otherwise it's basically impossible to write general-purpose tracers that don't want to take DLL dependencies on instrumented objects. The tags from opentracing are agreed upon by a few 3rd party tracers so I think using them should be a good thing! And every tracer could map them to its own anyway. * I'd argue that there should be *hundreds* of usages of this API in the future (every messaging library, database SDK, probably even frameworks that invoke user code like mvc actions, ...). Tracers should not (and can not) have DLL dependencies on all of these and it should be easy for tracers to automatically subscribe to all of these. * It uses **more common 128bit/64bit randoms for IDs** instead of the very complicated and also completely proprietary algorithm. This would ensure compatibility with some more 3rd party tracers. * Given this proposal has a more reliable way to subscribe to all start events and also inject/extract hooks, it might not even be necessary to dictate the format at all. This PoC probably has some issues and needs further discussion etc. I'd be happy to help work on this and create an initial PR should there be approval towards the general approach. If not, I'll (hopefully - no guarantees :smile:) finally shut up and continue to work on my OpenTracing library as an alternative. ```csharp // Usage in an outgoing Http Request async Task SendHttpRequest(HttpClient client, HttpRequestMessage request) { // NOTE: OperationName has a different meaning in OpenTracing.

On .NET Framework, it is a System.Net.ConnectStream (an internal class). Due to this, there are small behavior difference w.r.t. the exception returned while doing argument checking: See: ```c# [Fact] public void WriteAsync_OffsetPlusCountExceedsBufferLength_ThrowsArgumentException() { using (Stream stream = GetRequestStream()) { if (PlatformDetection.IsFullFramework) { // In .NET Framework, the request stream is a System.Net.ConnectStream // which throws ArgumentOutOfRangeException in this case.

For app-compat, we should consider fixing this. The simplest fix would be to create a derived class of MemoryStream() and make sure all Write* methods are overridden with matching argument validation before calling the base methods. 18788 area-System.IO How to check whether the PipeStream has data or not "In .NET, the pipe API doesn't expose any property the application can use in order to decide whether it's worth involving a Read operation or not. The other posts on this subject suggest using the async reading and CancellationToken for this. I don't like this very much because the Exception is intended to be used for exceptional cases only. Raising an OperationCancelledException every few milliseconds doesn't sound very appealing. Anyway, I tried that, as well. The reason I am writing this post is the fact that to me it seems the ReadAsync doesn't work either for this purpose. I guess this is because ReadAsync deals with unmanaged IO operations. IMO cancelling should, however, be possible when using PipeOptions.Asynchronous. Please see the code below; it's the Main of a console application. The code contains comments explaining what are the actual and the expected behaviors. Thank you, Ernest. ```csharp // This is the Main of a console application public void Main() { // This code is intended to verify if ReadAsync can be used to check the pipe doesn't have any data. string pipeName = ""XYZ""; // create the server (async)pipe and put it listenting mode var serverPipe = new System.IO.Pipes.NamedPipeServerStream(pipeName, System.IO.Pipes.PipeDirection.InOut,1,System.IO.Pipes.PipeTransmissionMode.Byte,System.IO.Pipes.PipeOptions.Asynchronous); var connWaiterTask = serverPipe.WaitForConnectionAsync(); // create the client pipe and connect it to server. The client intentionally doesn't send any data to the server. var clientPipe = new System.IO.Pipes.NamedPipeClientStream(""localhost"", pipeName, System.IO.Pipes.PipeDirection.InOut); //, System.IO.Pipes.PipeOptions.Asynchronous); clientPipe.Connect(); // prepare a cancellation source for ReadAsync System.Threading.CancellationTokenSource cts = new System.Threading.CancellationTokenSource(); byte[] inBuffer = new byte[1]; try { // invoke ReadAsync on the server pipe and immediately cancel the passed in cancellation token. var readAsyncTask = serverPipe.ReadAsync(inBuffer,0,1, cts.Token); System.Threading.Thread.Sleep(50); cts.Cancel(); // cancel ReadAsync //clientPipe.WriteByte(1); // If the client sends some data, it unblocks the ReadAsync on server side int n = readAsyncTask.Result; // The token is cancelled at this time, but ReadAsync doesn't seem to be aware of this.

However, it throws a `System.Runtime.InteropServices.COMException`. As far as I can see, there aren't any try/catch blocks around the QCalls into the CLR, so this exception is actually bubbling up through the invoke.

While the test intended to test a scenario with a ""server that slowly returned data"", it is testing it in the wrong manner. Returning an HTTP response with a Content-Length header that is geater than the number of bytes actually being returned will cause a client to wait until all promised bytes are returned. This is how, for example, the long-polling type of scenarios work. The fact the .NET Core is working and returning ""partial data"" doesn't seem right. I believe the bug is that .NET Core is not behaving as per RFC. And this test is testing something invalid.

If you look at [implementations mentioned on Wikipedia](https://en.wikipedia.org/wiki/Glob_(programming)#Implementations), every ""mainstream platform"" has an entry, but not .NET. There's quite a few (more or less) successful implementations around (see below), some even from Microsoft, but I think something as fundamental as this, should ship with the framework. There's already partial globbing support using the following methods - `Directory.GetFiles` - `Directory.EnumerateFiles` - `Directory.GetFileSystemEntries` - `Directory.EnumerateFileSystemEntries` - `Directory.GetDirectories` - `Directory.EnumerateDirectories` They all have a `searchPattern` argument, but it lacks support for recursive globs (`**` aka. ""globstar""), brace expansion etc. This can be achieved using the `SearchOption` argument, but the API is hard to use when you want to support (often user-defined) recursive patterns like `/src/**/*.csproj`. I'd ❤️ to hear people's opinions here... - Is it worth including in the framework? - Should new APIs be introduced, or can we ""level up"" the existing `searchPattern` in the methods mentioned above (without it being a breaking change)? ## Examples - [**MSBuild**](https://github.com/Microsoft/msbuild/tree/master/src/Build/Globbing) by @cdmihai - [**Cake**](https://github.com/cake-build/cake/blob/develop/src/Cake.Core/IO/Globber.cs) by @patriksvensson - [**Minimatch**](https://github.com/SLaks/Minimatch) (port from JS) by @SLaks - [**Microsoft.Extensions.FileSystemGlobbing**](https://github.com/aspnet/FileSystem/tree/dev/src/Microsoft.Extensions.FileSystemGlobbing) by @troydai - [**Glob**](https://github.com/kthompson/glob) by @kthompson And [tons of other implementations](https://github.com/search?utf8=%E2%9C%93&q=glob+NOT+global+NOT+globe+language%3Ac%23&type=Repositories)..." 18924 area-System.Threading Support controlling thread affinity "**Purpose** Allow control of thread affinity. **Proposed API** ```C# class Thread { ProcessorSet Affinity { get; set; } } ``` The `ProcessorSet` represents a a set of logical processors. The underlying APIs for Windows/Posix use bit masks for this. Windows: https://msdn.microsoft.com/en-us/library/windows/desktop/ms686247(v=vs.85).aspx Posix: http://man7.org/linux/man-pages/man3/pthread_setaffinity_np.3.html On Windows, systems with more than 64 processors are split into groups. Threads cannot use processors which belong to multiple groups. `ProcessorSet` can store the group info. ```C# struct ProcessorSet { int Group { get; set; } // get/set group bool this[int processor] { get; set; } // get/set/clear processor ProcessorSet(minCapacity); // actual capacity may be higher int Capacity { get; } // indexer is valid from [0-Capacity[ // string representation, see below string ToString(); static ProcessorSet Parse(string); static bool TryParse(string, out ProcessorSet); static ProcessorSet ForProcessor(int group, int processor); // set with single processor static ProcessorSet ForProcessor(int processor); // set with single processor } ``` The string representation can be a comma separated list of processors and ranges, prefixed with an optional processor group. E.g: `1`, `1-3,5`, `1:8-10`. **Example** ``` var thread = new Thread(threadStart); thread.Affinity = ProcessorSet.Parse(""0-3""); thread.Start(); ``` **Remarks** This proposal does not consider retrieving information from the OS like the number of groups and the number of processors per group. The total number of processors can be read from `Environment.ProcessorCount`. Posix threads inherit the calling thread affinity. It may be preferable to allow new Threads to run on all processors to avoid surprises. Threads that want to inherit the calling thread priority can explicitly do so: ```c# newThread.Affinity = Thread.CurrentThread.Affinity; ```" 18925 area-Serialization Disable XmlDictionaryWriter test Fixes: https://github.com/dotnet/corefx/issues/18899 See: https://github.com/dotnet/corefx/issues/18899#issuecomment-296928857 cc: @danmosemsft @shmao 18927 area-System.IO Fix IsolatedStorage difference in behavior and fix tests IsolatedStorageFile had some difference in behavior in between .Net Core and desktop where in desktop all the operations over a file/directory would throw `InvalidOperationException` if the file/directory is closed (which is also true if the item is deleted) but in .Net Core we would do an extra check if the item is deleted and throw an `IsolatedStorageException`.

After fixing this test bug, it then exposed a product bug where we leak an InvalidOperationException that isn't wrapped properly by an HttpRequestException. The scenario that exposed this related to POST'ing content that is non-rewindable and having to resubmit the POST due to authentication challenges. This test was passing on .NET Core because the test was written using the wrong assumptions. It failed on .NET Framework which exposed the problem. The InvalidOperationException comes from when a StreamContent's SerializeToStreamAsync method is called and the content needs to be rewound. If the content can't be rewound, then the exception is thrown with the error message ""The stream was already consumed. It cannot be read again.""

We validate for 1:1 packages to make sure that if the assembly is inbox it doesn't try to apply an assembly from the package. We generate the inbox list from targeting packs for frameworks that use a targeting pack so validation here isn't necessary. We hand-author the inbox state for package-based frameworks (UAP, NETCoreApp) and are missing validation for this. We should add it to the framework packages to make sure that anything in the ref folder for the framework must be marked inbox in the index. Anything inbox in the index for the framework must also be in the ref folder for that framework. /cc @weshaggard @joperezr 18938 area-System.Data I am new to dotnet core and i want my application to interact with sybase .

An example of a structure I use for native interop today. ```cs public struct MDBValue { public IntPtr size; public IntPtr data; public byte[] GetBytes() { var buffer = new byte[size.ToInt32()]; Marshal.Copy(data, buffer, 0, buffer.Length); return buffer; } //just demonstrating the problem public Span GetSpan() { var bytes = GetBytes(); //extra allocations this route //alternative is dropping to use unsafe, where at least currently the library doesn't require it return new Span(bytes); } } ``` Ideally, I would be able to do the following instead. ```cs public struct MDBValue { public IntPtr size; public IntPtr data; public Span GetSpan() { return new Span(data, 0, size.ToInt32()); } } ``` Looking at the pointer overload it looks like it's already using an IntPtr internally so I would think it wouldn't be all that difficult to do what I've proposed.

It's a heavily used API: https://apisof.net/catalog/System.Diagnostics.ProcessStartInfo.UseShellExecute eg up to 25% in Unity apps. It's also part of .NET Standard 2.0.

What happens with 192K? We could up both the stacksize and the size of the tree compiled to keep it testing what it is there to test without, though that increases execution time and the point is to do a similar job to the slower `CompileDeepTree_NoStackOverflow` without spending so long that it impacts heavily on how long the test suite takes. After a certain point the test no longer earns its keep, especially as there is that slower test being run on outerloop. --- @parjong commented on [Fri Apr 21 2017](https://github.com/dotnet/coreclr/issues/11122#issuecomment-296149779) @JonHanna Yes, this issue comes from a completely new configuration (x86/Linux Debug).

Clearly not the actual result. The ""slow"" one does the same thing with a more normal stack. If only the fast failed I might give it up as overly artificial, but the slow is triggering conditions that were causing users problems with real code, so I'm much more worried about that.

" 19017 area-System.Security Simplify X509Chain building with OpenSSL While looking into why some chain errors show on all certificates, vs just the ones where the problem originates, I ran across some information that would have simplified the work of building chains long ago. By providing the candidates set (including the values from ChainPolicy.ExtraStore) and the trusted store (the union of the CurrentUser\Root and LocalMachine\Root stores) in separate collections OpenSSL will tell us when the root was trusted or not. So we should do that, and get rid of our post-facto decision that says the root was not trusted after all. The error codes getting copied in multiple positions was an artifact of the callback being called at the end with `ok=1`. Most of the time the X509StoreCtxGetError value has been cleared to `X509_V_OK`, but some of them remain. By only reading error codes when `ok=0` they're not only placed on the element where we first read them. There's a fair body of tests which already verify LM\Root trust; and I manually verified behaviors with CU\Root. 19019 area-System.Threading Build System.Threading.Overlapped on uapaot 19021 area-System.Security Make RSASignaturePadding a required parameter for RSA certs "In the original API design we went back and forth on having a default for RSASignaturePadding. In the end we landed on convenience, and defaulted it to Pkcs1 (v1.5) padding since that is the most widely supported. Some additional feedback was given that suggested that we really didn't want to do that, after all, we had nicely made the digest algorithm a required parameter. This change makes RSASignaturePadding a required parameter for creating RSA certificates. As a consequence the Create method which uses a certificate now has more failure modes. 1) Hybrid algorithm signing is currently disallowed. Either ""RSA is special"", or ""you can only sign with the same algorithm so the options make sense"". We are currently using the latter, though they're almost identical given our current support matrix (2 algorithms). 2) Using Create(X509Certificate2) with .ctor(PublicKey) fails for RSA. This one ended up being ""RSA is special"". In this degenerate case we don't have enough data to know if the signing key is using Pkcs1 or PSS, and NIST guidance is to only use a single padding mode with an RSA private key; so we can't make any assumptions. (We can't even assume signed-with-Pkcs1 means signs-with-Pkcs1, unless it's self-signed)" 19022 area-System.Data Add Async flag to SqlClient NamedPipes' PipeStream to resolve an issue with connection hangs while using MARS over NP.

I strongly recommend that it also implement IEquatable<HashBucket> to remove the boxing penalty. Right now, comparison of HashBuckets falls back to the last-resort Equals() method implemented by System.ValueType. Which uses _Reflection_ to compare the fields of the HashBucket. So even on non-AoT platforms, you're taking a horrendous perf hit. On AoT platforms, the private fields get hidden from Reflection, thus causing Equals() to return true unconditionally. This is causing two tests to fail on AoT, and it's amazing that it's only two. ImmutableHashSetTest.EnumeratorWithHashCollisionsTest ImmutableHashSetTest.RemoveValuesFromCollidedHashCode @morganbr: I'll open a separate TFS item for the toolchain. There's a discoverable call to EqualityComparer<HashBucket>.Default in the code so if that doesn't kick the toolchain into emitting the auto-Equals method for HashBucket, it probably should.

While the SafeHandles help to avoid certain misuses, a) SafeHandle marshaling (and in particular the implicit use of DangerousAddRef/Release) already isn't being done for synchronous operations (presumably to enable operation cancelation by closing the handle concurrent with the operation), and it's only being done for asynchronous operations during the actual P/Invoke (and thus the SafeHandle isn't ""protected"" while the async operation is in flight). The benefit of the protection isn't worth the cost. This commit removes the marshaling for send/receive operations.

However, I've noticed that Activity's meaning of ""OperationName"" is different than OpenTracing's. Definition from the [OpenTracing specification](https://github.com/opentracing/specification/blob/master/specification.md#start-a-new-span): > An operation name, a human-readable string which concisely represents the work done by the Span (for example, an RPC method name, a function name, or the name of a subtask or stage within a larger computation). The operation name should be the most general string that identifies a (statistically) interesting class of Span instances. That is, ""get_user"" is better than ""get_user/314159"". > > For example, here are potential operation names for a Span that gets hypothetical account information: > > | Operation Name | Guidance | > |--------|--------| > | get | Too general | > | get_account/792 |Too specific | > |get_account | Good, and account_id=792 would make a nice Span tag | With Activity however, the OperationName is used as a compile-time constant that is used for the DiagnosticSource event names - e.g. ""System.Net.Http.HttpRequestOut"". Depending on how much you'd like to follow the OpenTracing standard, it might be good to rename the property to reduce confusion. I think that your usage might come closest to OpenTracing's standard tag ""[component](https://github.com/opentracing/specification/blob/master/semantic_conventions.md#span-tags-table)"" however using that might be confusing as well. Maybe it's best to call it just `Name` (and `activityName` if used as a parameter)?!

That’s because HttpClient has logic to Dispose of the request content once the Task returned from the handler’s SendAsync completes, and unlike WinHTTP, libcurl doesn’t require that the whole request be sent before any of the response is processed. That means that CurlHandler may receive the response (or the response headers), complete the SendAsync task, but still be reading from the request content, which may then be disposed of by HttpClient while it’s still in use, causing potential corruption, exceptions, etc. The Dispose behavior has other problems with it. A more generalized version of the above is that it prevents handlers that want to support full duplex communication, since it essentially requires that the whole request be sent before the response is processed. It also forces extra cost onto consuming code in some situations, as it means that the request content objects can’t be pooled and reused (since disposal typically invalidates objects for such a purpose, though in some cases a custom content could be developed to override and ignore Dispose). A variety of approaches were explored to address this: - Change CurlHandler to only complete the SendAsync Task when both the request has been fully sent and the appropriate portion of the response has been received. This is problematic, though, as with the pull model employed by libcurl, we don’t know reliably when the request has been fully sent. - Change the disposal to be handled by the handlers rather than by HttpClient. This could help in that a handler like CurlHandler could simply defer disposal until libcurl tells it the “easy” operation is done. But it has other downsides. Today code can use an HttpClientHandler without HttpClient, e.g. by using HttpMessageInvoker instead of HttpClient, in which case it bypasses this disposal logic (and other logic provided by the relatively thin HttpClient wrapper). If we were to move the disposal logic to the HttpClientHandler, now such code that was never having its request content disposed will start to, which is bad and exactly the opposite of what we want. It also causes problems for chains of handlers, e.g. if HttpClient is given a handler that wraps CurlHandler, and that handler expects to be able to look at the request content after the SendAsync Task from CurlHandler completes but before it itself completes its SendAsync Task. And while such a scenario may seem far fetched, we effectively have it in the bits today: the diagnostic handler that's used to pass details off to DiagnosticListeners is injected in the middle like this, and it does pass off the request content after the wrapped SendAsync Task completes... if a listener was expecting a non-disposed request content at that point, it would be sorely disappointed. - Simply stop disposing. The primary downside here is existing code that may have expected disposal to happen, e.g. if a StreamContent wrapping a FileStream isn't explicitly disposed of by the app code, cleanup of the FileStream will be left to its finalizer. The least bad option is to simply stop disposing. This PR makes that change.

But no, even with the below code it throws the same kind of exception. ```c# using (HttpClient httpClient = new HttpClient()) { HttpRequestMessage request = new HttpRequestMessage { RequestUri = new Uri(@""https://www.gravatar.com/caaa1c76de5cc0ceed0e32f3d4377f31.json""), Method = HttpMethod.Get, Headers = { { ""User-Agent"", ""csharp"" } } }; httpClient.Timeout = new TimeSpan(0, 0, 0, 5); string responseContent; using (HttpResponseMessage response = await httpClient.SendAsync(request, HttpCompletionOption.ResponseHeadersRead)) { if (response.StatusCode == System.Net.HttpStatusCode.Found && !string.IsNullOrEmpty(response.Headers.Location.PathAndQuery)) { HttpRequestMessage redirectRequest = new HttpRequestMessage { RequestUri = response.Headers.Location, Method = HttpMethod.Get, Headers = { { ""User-Agent"", ""csharp"" }, { ""Connection"", ""close"" } } }; using (HttpResponseMessage redirectResponse = await httpClient.SendAsync(redirectRequest, HttpCompletionOption.ResponseContentRead)) { var bytes = await response.Content.ReadAsByteArrayAsync(); responseContent = System.Text.Encoding.UTF8.GetString(bytes); } } } } ```" 19100 area-System.Runtime Fix param names for desktop runs Fix https://github.com/dotnet/corefx/issues/19096 and some others that don't seem filed 19101 area-System.IO [release 1.0/1.1] Add signing to windows native build We need to port the following change https://github.com/dotnet/corefx/pull/15962 to our release 1.0.0 and 1.1.0 branches so the are correctly signed on the next servicing event for them. 19102 area-System.Security Disable the other ProduceLegacyHmacValues test Fix https://github.com/dotnet/corefx/issues/19037 19103 area-System.Net Fix bogus Debug.Assert in WebSocketBuffer cc: @stephentoub 19104 area-System.Runtime Type.GetType Behaves Differently on netfx and netcore "The following test present different behaviors on netfx and netcore. ```c# [Fact] public static void TypeGetTypeTest() { Type t = Type.GetType(""Employee, http://www.contoso.com""); Assert.Null(t); } ``` When targeting netstandard or netcoreapp, `Type.GetType` returns null and the test passes; when targeting netfx, the test fails with the following exception, ``` ---- System.IO.FileLoadException : The given assembly name or codebase was invalid.

Added a lot of tests which should raise the code coverage to 80-90% 19119 area-System.Runtime Scale back [Serializable] for .NET Core 2.0 We brought [Serializable] and BinaryFormatter back for .NET Core 2.0 in the name of compat and helping code to migrate to core. But it comes with some serious implications, and it's becoming clear we took things too far. Doing this makes it very easy for code to take dependencies on private implementation details and will end up binding our hands for improvements/optimizations/refactorings/etc. in the future. And with all of the improvements/optimizations/refactorings/etc. already made in core, we've had to punt on the idea of cross-runtime serialization support. There needs to be a better happy-medium. The primary need for BinaryFormatter and [Serializable] is on a few core types, e.g. primitives, some of the core collections (e.g. `List`), some small wrapper types (e.g. `Tuple`), etc. Proposal from me and @morganbr for .NET Core 2.0: 1. BinaryFormatter and friends are currently implemented in System.Runtime.Serialization.Formatters.dll. We keep that as-is. 2. SerializableAttribute, ISerializable, etc. are all implemented in System.Private.CoreLib.dll and exposed through System.Runtime.dll. We keep that as-is. 3. We remove most of the [Serializable] implementations we added back for .NET Core 2.0, keeping the most core and important 10% or so. For this set, we a) potentially implement ISerializable if not already implemented in order to separate the implementation from the surfaced serialization state and to minimize the impact of future refactorings and optimizations, and b) try to enable desktop/core serialization/deserialization, so that BinaryFormatter'd state can go back and forth between desktop and core. We'll need to finalize what the list of types is, but it would include all of the primiteves (e.g. Int32), core collection types (e.g. Dictionary), core wrapper types (e.g. KeyValuePair), Exception and important Exception-derived types, and a handful of others. We can add more types in the future as they're highlighted as blockers, but in the meantime we avoid taking on the burden of lots of serializable types that'll hamper our ability to move the platform forward as we'd like.

This leads to the situation where the two calls to StreamWriter when doing this: ```csharp _streamWriter.Write('<'); _streamWriter.Write('/'); ``` runs significantly faster than the one call to StreamWriter when doing this: ```csharp char[] chars = new char[] { '<', '/'}; _streamWriter.Write(chars); ``` This is because Buffer.BlockCopy is always used with char arrays which is more expensive than a simple one char at a time array assignment in a loop. This is more expensive to the point that the overhead of an extra method call costs significantly less. When using the overload which takes a string, a similar issue occurs with a call to string.CopyTo.

However, if one tries to use these classes in the current release of Visual Studio 2017 to create designers for their classes, Visual Studio displays errors in the designer like ```c# using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; namespace CoreDesignerTest { public class Class1 : Component { } } ``` In Visual Studio, right-click on the ""Class1.cs"" node and choose ""View Designer"". > Could not load file or assembly 'System.ComponentModel.Primitives, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. With some hacking in my .config files, I can resolve the above error, but eventually Visual Studio fails to load the .Net Core assemblies with an ""Invalid Format"" error. I'm assuming this is due to the fact that Visual Studio, being a .Net Framework-based application, is trying to load a .Net Core assembly into a .Net Framework application, and therefore failing. My question is, with the coming release of .Net Core 2.0 and .Net Standard 2.0, will there also be an accompanying Visual Studio update that will provide the ability to create designers for .Net Core 2.0 and .Net Standard 2.0 classes?" 19140 area-System.Collections Remove dead code from System.Collections Didn't see the pull from @Olafski for #17905.

I've tried to define as shown below: public class Curves { // TODO: check the key gen rand. work in progress. check constants. public static ECCurve Curve25519 { get { return new ECCurve() { CurveType = ECCurve.ECCurveType.PrimeMontgomery, B = new byte[] { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1}, A = new byte[] {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,7,109,6}, G = new ECPoint() { X = new byte[] { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9}, Y = new byte[] {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }}, Prime = new byte[] { 127, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 237 }, Order = new byte[] {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,8}, Cofactor = new byte[] { 1 }, // fix later }; } } and later call ``` var ecc2 = ECDsa.Create(Curves.Curve25519); ``` This throws a null pointer exception, which does not make any sense to me. When we call the `Validate` method on the curve, everything seems to works. What is the reason behind this null pointer exception? 19171 area-Infrastructure Update guidance to include special types I noticed a handful of tests substituting int for a value type, which does not always do what you might want.

This means that a read operation that falls into this case will call `FlushFinalBlock` on `Dispose` - which throws an exception in the proprietary stream I'm using for reading. A `Flush` is never expected on stream used for reading only. The last thing that needs to be checked in the `if (bytesToDeliver >= numOutputBytes)` block is whether `bytesToDeliver` has gone to zero, in which case we should go to the `ProcessFinalBlock` label code. I've attached a solution to reproduce and included a copy of `CryptoStream` that with a one line fix. **Repro Steps:** Basically, attempt to read (decrypt) a stream that falls into the ""slow"" label and into the `if (bytesToDeliver >= numOutputBytes)` block with `bytesToDeliver == numOutputBytes`. Impact: For me, I get intermittent crashes when I read a stream of a particular length that just happens to fall into this case - `Flush` is called on a stream that accepts no write operations." 19195 area-System.Diagnostics HttpHandlerDiagnosticListener: Write response event once when request is redirected HttpHandlerDiagnosticListener was introduced in #18101. It allows to hook into the .NET Framework `HttpClient` implementation based on `HttpWebRequest` and get notifications with `DiagnosticSource` and inject correlation headers (similar to [corefx](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/DiagnosticsHandler.cs) instrumentation). When HTTP request is redirected, the hook is invoked once per redirect. when request is being sent, the hook only sends one event for the first request and does not notify about each consecutive redirect. When response is received, hook sends event for each response. Consumers of these events uses them to log requests/responses and having the 'final' response code, actual duration and potentially details from the response is important. So every consumer for the hook needs to wait for the last response. This fix implements it: it does not send `Stop` event * if automatic redirects are allowed * and response status code is one of the redirected ones * and number of redirects is not reached maximum allowed Otherwise it notifies consumer about the 'final' response. /cc @vance @davidsh 19196 area-Infrastructure Update CoreClr, CoreFx, ProjectNTfs, ProjectNTfsTestILC, Sni to preview2-25302-01, preview2-25302-01, beta-25302-00, beta-25302-00, preview2-25302-01, respectively (master) 19197 area-System.Data Modifying the SNI identity package to pick up the new SNI package names.

The proposal is to add a new attribute to `System.Runtime.CompilerServices` namespace similar to`IsReadOnly`, named `IsRefLike`. The purpose of the attribute is to request that all the requirements of ref-like structs be applied to the type by the compiler. Such struct will be allowed to have instance fields that are ref-like types (and typically will have such fields). # Proposed API ```csharp // .NET Core: // System.Runtime (reference assembly) // System.Private.CoreLib (implementation) // .NET Framework 4.7++ // mscorlib // .NET Standard 2.0++ // netstandard namespace System.Runtime.CompilerServices { [AttributeUsage(AttributeTargets.Struct)] public sealed class IsByRefLikeAttribute: Attribute { public IsByRefLikeAttribute(); } } ``` To ensure that using this type is an error on old compilers and compilers not familiar with safety rules of ByRefLikeStructs compiler will also emit an `Obsolete` attribute with a predefined message that can be filtered out by compilers that do know how to operate with spans. ```csharp [Obsolete(""ByRefLike types are not supported in this version of your compiler."", true)] ``` So a typical ref like struct will look like the following in the source: ```csharp ref struct TwoSpans { // can have ref-like instance fields public Span first; public Span second; } // error: arrays of ref-like types are not allowed. TwoSpans[] arr = null; ``` and like the following in metadata ```csharp [IsRefLike] [Obsolete(""ByRefLike types are not supported in this version of your compiler."", true)] public struct TwoSpans { . . . . } ```" 19213 area-System.Reflection Make AddCodeViewEntry(..., int age) public "Add an overload of AddCodeViewEntry API for building CodeView Debug Directory entry with specified Age != 1. ```C# namespace System.Reflection.PortableExecutable { class DebugDirectoryBuilder { /// /// Adds a CodeView entry. /// /// Path to the PDB.

Related issue: https://github.com/dotnet/coreclr/issues/6206#issuecomment-295339778 https://github.com/dotnet/core-setup/issues/2050 Fix #18776 19233 area-System.Security Fix random crashes from RSA.ExportParameters on Linux The RSAOpenSsl ExportParameters passed a SafeHandle into a function to get interior pointers to the key parameters, which was the last usage of that SafeHandle. If the parent RSA object had become unrooted then the key is now untracked and subject to finalization, which will free the underlying RSA structure and invalidate the memory to which the interior pointers are pointing. There are two obvious fixes: 1) GC.KeepAlive in ExportRsaParameters right before returning parameters. This would keep the GC from allowing the key to get finalized until after we had finished extracting the data from the interior pointers. But GC.KeepAlive doesn't protect against multithreaded releasing. 2) DangerousAddRef the SafeHandle. AddRef the key before extracting the data and Release it when done so that the object is both GC rooted and safe from a parallel free. As it happens, ECDsaOpenSsl and DSAOpenSsl both already did AddRef/Release, only RSAOpenSsl was shooting from the hip. Due to a missing `using` block RSACertificateExtensions.CopyWithPrivateKey had the last use of cert.GetRSAPublicKey() be the call to ExportParameters(false), which left the RSA object untracked by this method. ExportParameters(false) then grabbed the key reference, and no longer needed `this`, making the object wholly untracked. The key object's last proven use was the call to RsaSize between extracting and using the interior pointers, and so under COMPlus_GCStress=3 this path always freed the underlying key between RsaSize(key) and ExtractBignum(n).

The second zero-length chunk was ok since it means end of data. The first zero-length chunk was because it was the empty string being encoded. This was causing problems by sending extra data to WinHTTP and hence to the server. Any subsequent requests to the server might get mis-understood by the server and the server would then send back an error. That translated to getting a WinHTTP error (12152) ""The server returned an invalid or unrecognized response"". This is hard to repro except in the HttpListener tests because of the timing of when the extra zero-length chunk of request data gets sent to the server. There is already an HttpClient unit test for POSTing zero-length data using chunked encoding. But this was not triggering this error due to timing issues. Even the HttpListener test needed to be adjusted to force a consistent repro. Added asserts to validate the logic of making sure that we don't try to chunk encode zero length data. Fixes #18869." 19252 area-System.Security Clean up X509Certificates test conditions A hacky capability, `IsReliableInCI`, was created to overcome test failures during the final days of .NET Core 1.0 when a new configuration came online with a CI tmphome on a fuseblk (NTFS) volume instead of an EXT volume. The infrastructure bug has survived longer than anticipated and the capability is continually updated as new configurations encounter the problem. The capability is very loosely structured, and that is costing us test coverage. Our Helix machines are believed to not have the same limitation, so they could run the tests. A private Ubuntu 16.04 stock machine won't have the limitations, and could run the tests. Only in our CI system does it actually fail. This change introduces a new class, TestEnvironmentConfiguration, which has a partial method to determine the baseline chmod requirements of the persisted files store to assess that the tests won't make sense to run, and the `IsReliableInCI` condition has been renamed to `CanModifyStores`. In order to not have TestEnvironmentConfiguration be a one-trick-pony the change also introduces a `RunManualTests` value to allow for those tests which are not even OuterLoop-reliable to be opted into. Painting a method as a manual test is hoped to not be a very common occurrence, but it is occasionally valueable to indicate that a test is present, but not running. 19257 area-System.Data Re-enable managed SNI by default in SqlClient EntityFramework test failures in https://github.com/dotnet/corefx/issues/19057 have been resolved (aside from occasional command timeouts), so re-enabling SqlClient managed SNI by default in master 19258 area-Serialization Add Tests covering WCF Soap Scenario.

But it was accidentally being run all four times with the same Task-based implementation. When fixing that, it highlighted that a) we throw ObjectDisposedException in this situation in the APM case (because the EndReceive call does a CleanedUp check before inspecting the IAsyncResult), and b) that we have a small difference of behavior on netfx due to the Task-based implementation for netfx wrapping the APM implementation rather than the EAP implementation, and thus surfacing the difference noted in (a). Fixes https://github.com/dotnet/corefx/issues/19281 19295 area-System.Reflection Proposal : runtime attributes **Summary** Making easier to extend existing classes with attributes **Motivation** Sometimes we find us in situation when we want to attribute being dynamically added to a class that didn't have it before. It may be `Serializable`, `DataContract` or tons of `Validation`. Very viable example is that we want to display some model in UI and validate user inputs. In Microsoft stack you have to do it using `unobtrusive attributes` and MVC takes all care about it. But you cannot reference `Microsoft.Mvc.Razor` from model just because you want some validation for obvious reasons. And here you have to write some ViewModels that is just like a model, but has attributes. You have to write a ViewModel not because you want to add some indirection, but because language itself makes you to do it. **Design** I propose use the same mechanism that is using for inheritance and interfaces. Object can inherit one and only one parent (and overrides address in methodtable) and it has a list of interfaces and implementations of interface methods. I propose something similar: we can just add something like `DynamicAttributesList`, which can be freely populated and cleared by reflection methods. When you call `GetAttributes` it concat results of current implementation of `GetAttributes` and attributes from this list. We already have `System.ComponentModel.TypeDescriptor`, but we may want closer integration with methods such as mentioned `GetAttributes`, because otherwise it's a bit useless. I don't see this change breaks anything in any way, it's quietly easy to implement it and it simplify some cases a lot. 19298 area-Infrastructure Add repo name explicitly to symbol publish leg skip ci please `DotNet-CoreFX-Trusted` is the same as the default value specified in the build leg's checked-in json, but it seems that setting it manually might be necessary because the symbol leg broke while the package publish leg didn't.

Since the distro changing libcurl to use openssl11 could occur even with OpenSSL 1.0 still being on the system the only sign of problems we have are things like segfaults; so we should fix this for the 2.0 release before it becomes prevalent.

Then it will make an initial call to ExpandEnvironmentStringsW with the StringBuilder and the tracked currentSize. The length will be insufficient, so the Win32 call will fail and return the required size. But the runtime marshaling for the StringBuilder doesn't know it failed, so it dutifully marshals back the results of the call, and in doing so, ends up increasing the capacity of the StringBuilder and, importantly, increasing its Length, such that the Length is now larger than both the required size and currentSize. It will then try to increase the capacity of the builder to the required size, but the length and capacity are already longer than that, and the call to set the Capacity will throw due to it being perceived as losing data. The short-term fix is simple: just clear the builder before rather than after changing its capacity. A better longer-term fix is to stop using StringBuilder entirely; it adds overhead for little benefit.

These are the last tests failing in CI for the PKCS test assembly. Note that the `IsNetfx462OrNewer` function only checks the running framework version, not the highest framework version available on the system. This is somewhat problematic since the fix came in 462 and is non-quirked. The end result of this is that these tests will be ignored when the running TFM is =net462 is available even when they will actually pass. It's not perfect, but it at least absolutely disables the tests when they would fail (i.e. when 461 is the highest available framework version). cc: @bartonjs @krwq resolves https://github.com/dotnet/corefx/issues/19090 19363 area-Infrastructure Source init-tools rather than execute Sourcing init-tools.sh rather than executing it, prevents it from spawning a new process.

A system-specific return code is used instead. @stephentoub explains below: > 134 as the exit code is generally what you get from a .NET process exiting with an unhandled exception or with an abort() or a failed native assert(), as all of these trigger a SIGABRT, which is signal number 6... add the signal number to 128 (just a magic offset), and you get 134. So this Equal failure is saying it expected an exit code of 42 (which is SuccessExitCode, i.e. the app successfully ran what it was supposed to), but instead got 134 (the app crashed with an unhandled exception). Edited, was: `exitCode` is not initialized before use: https://github.com/dotnet/corefx/blob/c0bfbda2e1e8a1f4e39bd5e0b0642edff044f7b2/src/Common/tests/System/Diagnostics/RemoteExecutorConsoleApp/RemoteExecutorConsoleApp.cs#L42 19375 area-System.Security Issue with WindowsIdentity.RunImpersonated "I am having issue using RunImpersonated with dotnet core 1.1.

This experience can be improved if the missing prerequisite is acquired, and made available for the build to consume. Summary of changes: 1. Metadata of each required build tool will be in `.toolversions` file located in repository root 2. Native build invokes a probing mechanism to get a required tool. Build should specify the name of the required tool. Optionally build can also specify if the declared version, which the version that has been verified to work correctly with the product, of the tool is required. Probing mechanism invokes search and acquire scripts to get the tool on behalf of the build, and returns the tool path if successful or an error message. 3. Scripts that search and acquire a tool will be in `tools-local` folder in repository root. Short description of the design is provided below. Implementation of this design for probing CMake is ready. The design of these scripts is like having ISearchTool and IAcquireTool interfaces. ISearchTool provides a base implementation of searching for the specified tool in environment path, and the search paths specified in the tools metadata file. Base implementation is in `tools-local/unix/search-tool.sh`, and a corresponding PowerShell script for Windows. A tool can override this implementation if it wants to follow a customized search process. This override script will go into the tool specific folder. For example, if CMake overrides the base implementation then, the override script should be in `tools-local/unix/cmake/search-tool.sh`. ISearchTool has abstract methods that each tool must provide an implementation. For example, `get-version.sh` gets the version of CMake at the specified path. This script will be in tool specific folder at `tools-local/unix/cmake/get-version.sh`. IAcquireTool provides similar virtual and abstract functions for acquiring a tool. Entry point to these scripts is `probe-tool.sh` that gets invoked by `src/Native/build-native.sh`. In the current implementation, a tool is downloaded directly from the internet. If a developer would like to acquire the tool from a different location, then the developer can either modify `tools-local/unix/acquire-tool.sh` within the local repository or have the customized script in a folder rooted outside the repository. Path to the folder containing such customized scripts can be specified using `OverrideScriptsFolderPath` argument. A future addition would be to provide an option to override the default `.toolversions` file. @weshaggard @ellismg PTAL. 19408 area-System.Collections Add ImmutableInterlocked.Update for ImmutableArray The current [`ImmutableInterlocked.Update`](https://msdn.microsoft.com/en-us/library/system.collections.immutable.immutableinterlocked.update.aspx) overloads work for each of the immutable collection types except `ImmutableArray`. It would be valuable, e.g. in dotnet/roslyn#19267, to have an overload which covers this case. I propose the addition of the following specific methods to `ImmutableInterlocked`: ``` public static bool Update( ref ImmutableArray location, Func, ImmutableArray> transformer); public static bool Update( ref ImmutableArray location, Func, TArg, ImmutableArray> transformer, TArg transformerArgument); ``` 19410 area-System.Security System.Security.Cryptography.Xml.XmlLicenseTransform.GetOutput improperly checks type of document See here for reference: https://github.com/dotnet/corefx/commit/ce11eb43170125c54e8c368429d741e3d6ae6c22#diff-f156a7b1230342829b2a7663d45119ecR128 19412 area-System.IO Add tests for UMS PositionPointer overflowing Adds some tests for https://github.com/dotnet/coreclr/pull/11376 which resolved https://github.com/dotnet/coreclr/issues/11199.

debug-build-only change augments exceptions created using CreateExceptionUsingError to include the calling thread's stack trace, so that when these exceptions are then moved to other threads and propagated there, we can better correlate where they came from. Related to https://github.com/dotnet/corefx/issues/7812 cc: @davidsh, @steveharter 19416 area-System.Runtime Add support for getting current stack into Exception When writing managed wrappers for native components, it's common to create an Exception in one location (e.g. in a callback from native that includes an error code) and to then pass that off to a completely different location (e.g. storing the Exception into a TaskCompletionSource, with its Task awaited somewhere else). In doing so, the created Exception object doesn't contain any stack trace information about the original location where it was created, sometimes making it difficult to track down where it came from. It would be very helpful if there were a way of storing the equivalent of Environment.StackTrace into an Exception object. It's possible to do: ```C# try { throw e; } catch { } ``` but that doesn't really help, as the stack trace will only include the calling frame, not the entire stack, since the stack will stop after the catching frame. It would be helpful to have an API like: ```C# public class Exception { ... public void AppendCurrentStackTrace(); ... } ``` or something like that. Alternatively it could live on ExceptionDispatchInfo, e.g. ```C# public static class ExceptionDispatchInfo { ... public static void AppendCurrentStackTrace(Exception source); ... } ``` Workarounds today involve using reflection to access privates of Exception, e.g. _remoteStackTraceString. cc: @gkhanna79, @jkotas 19418 area-Serialization Area-Serialization Sprint 118 The issue is for tracking issues to be done in sprint 118 (due by 5/26/2017) 19419 area-System.Net Ignore lack of CURLMOPT_MAX_HOST_CONNECTIONS in CurlHandler Versions before 7.30 don't have this option.

However, with `ImmutableDictionary<>` it's necessary to specify the type parameters via `ImmutableDictionary.Empty.Add(key, value)`, since there is no `Create(TKey, TValue)` method that does type inference. I have just run into a couple of scenarios where I need to create a singleton dictionary, and it would be really nice to have such a factory method around. ## Proposal ```cs public static class ImmutableDictionary { public static ImmutableDictionary Create(TKey key, TValue value); // Not strictly necessary for this proposal, but provided for completeness because ImmutableHashSet has a similar overload. // Feel free to object. public static ImmutableDictionary Create(IEqualityComparer keyComparer, TKey key, TValue value); // Create(IEqualityComparer, IEqualityComparer, TKey, TValue) not offered because one can just do // ImmutableDictionary.Create(keyComparer, valueComparer).Add(key, value) and type inference will work correctly. } ``` Overloads to create a dictionary with more than one key/value pair will not be provided because `params` won't work. If someone wants to do that, they can write `ImmutableDictionary.Create(key1, value1).Add(key2, value2)` and so on. 19450 area-System.Globalization Implement ISO week numbers "In most of EU and Asia, we have the concept of week numbers. They are defined by an ISO standard (ISO 8601). ISO week numbers are used by millions of people. For example, the entire medical and school system in Scandinavia, and possibly the entire EU. According to Wikipedia ISO week numbers are used in ""EU and most of other European countries, most of Asia and Oceania"". ISO week numbers are still not implemented in .NET Framework, forcing developers to implement workarounds. Also, it's easy to miss that it's not implemented, creating subtle bugs in applications that only appear every 4 years or so. As a side note, I first reported this as a missing feature to Microsoft in May 2003 when I discovered the problem in .NET Framework v1.0.3705. Celebrating the 14th anniversary of my initial report, I've now considered implementing it myself ;) Or at least start discussions about implementing it. Because when I started digging into the source code, I fell into a rabbit hole. The problem is we have to choose between two bad options: 1. Implement ISO week numbers entirely correctly, but possibly breaking stuff. If we're lucky, we're only breaking a few workarounds. This means changing the week rules for various countries implemented in the Framework since the start (from FirstFourDayWeek to ISO). 2. Implement ISO week numbers as an entirely optional feature, only usable when calling the GetWeekOfYear function and always having to explicitly state the ISO week number rule. (We cannot rely on the week rule of the current culture). The actual code changes would be very small with this option. Am I correct in assuming option 2 is the only realistic one? (I'm avoiding option 3, to implement nothing).

So in the test when we cast a value greater than uint.MaxValue to the 4-byte byte* we only get the uint.MaxValue bytes.

Because the LingerTime value is arbitrarily set by us, some slow computers may take more time to finish the send/receive operation, so it's possible that some data are still available before we dispose the socket. And in this case, we will use a RST packet (instead of FIN) to forcibly close the connection after time out (https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/src/System/Net/Sockets/Socket.cs#L4649, related issue #13114), and test will fail with System.Net.Sockets.SocketException, Message: An existing connection was forcibly closed by the remote host. An example is #19428 Potential fix: always use socket.Shutdown(SocketShutdown how) before we dispose() the socket. cc: @davidsh @CIPop @stephentoub 19508 area-System.Security macOS: cannot add self-signed cert to X509Store CurrentUser\My "**Repro** 1.

Rational struct often came up as an example And so I think that Rational actually useful. Normally approximate number with float. `3 * (1 / 3f)` is not became what we would expect. Floating point error need to be handled everywhere since we program in C Most of the time we care about precision than the range of number. If we could naturally use `Rational` in code it could make a lot of sense in many calculation logic And instead of always making Rational on our own then overriding all operators just about conversion between each number type. I think it could be useful enough to have it built in ```C# struct Rational64 { public int Number,Divider; } struct Rational128 { public long Number,Divider; } // Both will have long list of overload operator and implicit operator Rational64 f = 3; // implicit operator for int. Became Rational64(3,1) Rational64 f3 = 1 / f; // operator / will flip Number and Divider var three = 9 * f3; // 9 * 1 / 3 became Rational64(9,3). Should it always find LCM or just did it only when overflow? ``` ### ps We actually could handle internal value like this ```C# struct Rational64 { uint divider; public int Number; public uint Divider { get => divider + 1; set => divider = value - 1 } public double Value { get => Number / (double)Divider; } } ``` With this we will always handle negative only in number. And zeromemory will be `0 / 1` ### ps2 Should we also add `Irrational` and `Algebraic` object too? ```C# struct Irrational64 // Actually just 1 order of power for polynomial calculation { public Rational64 Value; public Rational64 Power; } struct Irrational128 { public Rational128 Value; public Rational128 Power; } class Algebraic128 // The real Irrational { public Rational128 Value = 0 / 1R; public Algebraic Power = null; // Unlike Irrational, can contain chain of power public static implicit operator double(Algebraic128 value) => Math.Pow((double)Value,Power ?? 1); } ``` I think most of calculation we use in graphics and physics simulation could be use `Irrational128` in general ### ps3 From csharplang repo I was propose this feature to have literal syntax. And there are suggestion that it should at least make the object itself pass corefx first 19522 area-Meta Disable desktop tests Disabling more desktop tests to get a clean run on CI. cc: @danmosemsft 19523 area-Infrastructure Fix Windows 7 outer loop runs Fix https://github.com/dotnet/corefx/issues/19480 `${osGroup}` is null per the log in the bug.

1.1.3 ## Advisory FAQ ### How do I know if I am affected? .NET Core and ASP.NET Core have two types of dependencies: direct and transitive. If your project has a direct or transitive dependency on any of the packages and versions listed above, you are affected. Note: As part of patching ASP.NET Core MVC we update every Microsoft.AspNetCore.Mvc.* package. If, for example, you have a dependency on `Microsoft.AspNetCore.Mvc` you should update to the appropriate version first (1.0.x should be updated to 1.0.4, 1.1.x should be updated to 1.1.3), and it will also update any other vulnerable ` Microsoft.AspNetCore.Mvc` dependency. ### NET Core Project formats .NET Core has two different project file formats, depending on what software created the project. 1. `project.json` is the format used in .NET Core 1.0 and Microsoft Visual Studio 2015. 2. `csproj` is the format used in .NET Core 1.1 and Microsoft Visual Studio 2017. You must ensure you follow the correct update instructions for your project type. ### Direct Dependencies Direct dependencies are dependencies where you specifically add a package to your project. For example, if you add the `Microsoft.AspNetCore.Mvc` package to your project then you have taken a direct dependency on` Microsoft.AspNetCore.Mvc`. Direct dependencies are discoverable by reviewing your `project.json` or `csproj` file. ### Transitive Dependencies Transitive dependencies occur when you add a package to your project that in turn relies on another package. For example, if you add the `Microsoft.AspNetCore.Mvc` package to your project it depends on the `Microsoft.AspNetCore.Mvc.Core` package (among others). Your project has a direct dependency on `Microsoft.AspNetCore.Mvc` and a transitive dependency on the `Microsoft.AspNetCore.Mvc.Core` package. Transitive dependencies are reviewable in the Visual Studio Solution Explorer window, which supports searching, or by reviewing the `project.lock.json` file contained in the root directory of your project for `project.json` projects or the `project.assets.json` file contained in the obj directory of your project for `csproj` projects. These files are the authoritative list of all packages used by your project, containing both direct and transitive dependencies. ## How do I fix my affected application? You will need to fix both direct dependencies and review and fix any transitive dependencies. The affected packages and versions in the previous “Affected Software” section include each vulnerable package, the vulnerable versions, and the patched versions --- **Note**: If you are using ASP.NET Core MVC in your projects you should first update the `Microsoft.AspNetCore.Mvc` version according to the affected versions table above. If you are currently using version 1.0.0, 1.0.1, 1.0.2 or 1.0.3 you should update your package version to 1.0.4. If you are using version 1.1.0, 1.1.1 or 1.1.2 you should update your package version to 1.1.3. This will update every MVC package to the fixed versions. --- ### Fixing Direct Dependencies – project.json/VS2015 Open your `project.json` file in your editor. Look for the dependencies section. Below is an example dependencies section: ``` json ""dependencies"": { ""Microsoft.NETCore.App"": { ""version"": ""1.0.1"", ""type"": ""platform"" }, ""Microsoft.AspNetCore.Server.Kestrel"": ""1.0.1"", ""Microsoft.AspNetCore.Mvc "": ""1.0.1"", } ``` This example has three direct dependencies: `Microsoft.NETCore.App`, `Microsoft.AspNetCore.Server.Kestrel` and `Microsoft.AspNetCore.Mvc`. `Microsoft.NetCore.App` is the platform the application targets, you should ignore this. The other packages expose their version to the right of the package name. In our example, our non-platform packages are version 1.0.1. Review your direct dependencies for any instance of the packages and versions listed above. In the example above, there is a direct dependency on one of the vulnerable packages, `Microsoft.AspNetCore.Mvc` version 1.0.1. To update to the fixed package, change the version number to be the appropriate package for your release. In the example, this would be updating `Microsoft.AspNetCore.Mvc` to 1.0.4. After updating the vulnerable package versions, save your `project.json` file. The dependencies section in our example `project.json` would now look as follows: ```json ""dependencies"": { ""Microsoft.NETCore.App"": { ""version"": ""1.0.1"", ""type"": ""platform"" }, ""Microsoft.AspNetCore.Server.Kestrel"": ""1.0.1"", ""Microsoft.AspNetCore.Mvc"": ""1.0.4"", } ``` If you are using Visual Studio and save your updated `project.json` file, Visual Studio will restore the new package version. You can see the restore results by opening the Output Window (Ctrl+Alt+O) and changing the Show output from drop-down list to Package Manager. If you are not using Visual Studio, open a command line and change to your project directory. Execute the `dotnet restore` command to restore your new dependency. After you have addressed all of your direct dependencies, you must also review your transitive dependencies. ### Fixing Direct Dependencies – csproj/VS2017 Open your `projectname.csproj` file in your editor, or right click the project in Visual Studio 2017 and choose `Edit projectname.csproj` from the content menu, where projectname is the name of your project. Look for `PackageReference` nodes. The following shows an example project file: ``` XML netcoreapp1.1 $(PackageTargetFallback);portable-net45+win8+wp8+wpa81; ``` The example has two direct package dependencies, as seen by the two `PackageReference` elements. The name of the package is in the Include attribute, and the package version number is in the Version attribute that is exposed to the right of the package name. The example shows two packages `Microsoft.AspNetCore` version 1.1.1, and `Microsoft.AspNetCore.Mvc.Core` version 1.1.2. Review your `PackageReference` elements for any instance of the packages and versions listed above. In the example above, there is a direct dependency on one of the vulnerable packages, `Microsoft.AspNetCore.Mvc` version 1.1.2. To update to the fixed package, change the version number to the appropriate package for your release. In the example, this would be updating `Microsoft.AspNetCore.Mvc` to 1.1.3. After updating the vulnerable package version, save your `csproj` file. The example `csproj` would now look as follows: ``` XML netcoreapp1.1 $(PackageTargetFallback);portable-net45+win8+wp8+wpa81; ``` If you are using Visual Studio and save your updated `csproj` file, Visual Studio will restore the new package version. You can see the restore results by opening the Output Window (Ctrl+Alt+O) and changing the Show output from drop-down list to Package Manager. If you are not using Visual Studio open a command line and change to your project directory. Execute the `dotnet restore` command to restore your new dependency. ### After updating your direct dependencies Recompile your application. If after recompilation you see a Dependency conflict warning, you must update your other direct dependencies to the appropriate version. For example if your project refers to `Microsoft.AspNetCore.Routing` with a version number of 1.0.1 when you update your `Microsoft.AspNetCore.Mvc` package to 1.0.4, compilation will throw: `NU1012 Dependency conflict. Microsoft.AspNetCore.Mvc.Core 1.0.4 expected Microsoft.AspNetCore.Routing >= 1.0.4 but received 1.0.1` To fix this, edit the version for the expected package to be the version expected by updating your `csproj` or `project.json` in the same way that you used to update the vulnerable package versions. After you have addressed all of your direct dependencies, you must also review your transitive dependencies. ### Reviewing Transitive Dependencies There are two ways to view transitive dependencies. You can either use Visual Studio’s Solution Explorer, or you can review your `project.lock.json` (project.json/VS2015) or `project.assets.json` (csproj/VS2017) file. #### Using Visual Studio Solution Explorer (VS2015) If you want to use Visual Studio 2015, open your project in Visual Studio 2015 and then press Ctrl+; to activate the search in Solution Explorer. Search for each of the vulnerable package names and make a note of the version numbers of any results you find. For example, searching for `Microsoft.AspNetCore.Mvc.Core` in an example project that contains a reference to `Microsoft.AspNetCore.Mvc` shows the following results in Visual Studio 2015. ![vs2015](https://cloud.githubusercontent.com/assets/796298/25858059/a1ae6624-348f-11e7-9ce9-ff2d25a3fc5b.png) The search results appear as a tree. In these results, you can see we have found references to `Microsoft.AspNetCore.Mvc`, version 1.0.1, ` vulnerable version. The first entry under the References heading refers to the target framework your application is using. This will be `.NETCoreApp`, `.NETStandard` or `.NET-Framework-vX.Y.Z` (where X.Y.Z is an actual version number) depending on how you configured your application. Under your target framework will be the list of packages you have directly taken a dependency on. In this example, the application takes a dependency on `Microsoft.AspNetCore.Mvc`. `Microsoft.AspNetCore.Mvc` in turn has leaf nodes that list its dependencies and their versions. In this case the `Microsoft.AspNetCore.Mvc` package takes a dependency on a vulnerable version of `Microsoft.AspNetCore.Mvc.Core` and numerous other packages. #### Manually reviewing project.lock.json (project.json/VS2015) Open the `project.lock.json` file in your editor. We suggest you use an editor that understands json and allows you to collapse and expand nodes to review this file; both Visual Studio and Visual Studio Code provide this functionality. If you are using Visual Studio the `project.lock.json` file is “under” the `project.json` file. Click the right pointing triangle, ▷, to the left of the `project.json` file to expand the solution tree to expose the `project.lock.json` file. The following image shows a project with the `project.json` file expanded to show the `project.lock.json` file. ![project lock json](https://cloud.githubusercontent.com/assets/796298/25858179/f6e01200-348f-11e7-8a77-7176d8dd3f03.png) Search the `project.lock.json` file for each of the vulnerable packages, using the format `AssemblyName/`. If you find any vulnerable assembly name in your search examine the line on which they are found, the version number is after the `/` and compare to the vulnerable versions table above. For example a search result that shows `Microsoft.AspNetCore.Mvc.Core/1.0.1` is a reference to v1.0.1 of `Microsoft.AspNetCore.Mvc.Core`. If your `project.lock.json` file includes references to any of the vulnerable packages shown above then you will need to fix the transitive dependencies. #### Fixing transitive dependencies (project.json/VS2015) If you have not found any reference to any vulnerable packages this means none of your direct dependencies depend on any vulnerable packages or you have already fixed the problem by updating the direct dependencies. If your transitive dependency review found references to any of the vulnerable packages you must add a direct dependency to the updated package to your `project.json` file to override the transitive dependency. Open your `project.json` and find the dependencies section. For example: ``` json ""dependencies"": { ""Microsoft.NETCore.App"": { ""version"": ""1.0.1"", ""type"": ""platform"" }, ""Microsoft.AspNetCore.Server.Kestrel"": ""1.1.0"", ""Microsoft.AspNetCore.Mvc"": ""1.1.0"" } ``` For each of the vulnerable packages your search returned you must add a direct dependency to the updated version by adding it to the `project.json` file. You do this by adding a new line to the dependencies section, referring the fixed version. For example, if your search showed a transitive reference to the vulnerable `System.Net.Security` version 4.0.0 you would add a reference to the appropriate fixed version, 4.0.1. Edit the `project.json` file as follows: ``` json ""dependencies"": { ""Microsoft.NETCore.App"": { ""version"": ""1.0.1"", ""type"": ""platform"" }, ""System.Net.Security"": ""4.0.1"", ""Microsoft.AspNetCore.Server.Kestrel"": ""1.1.0"", ""Microsoft.AspNetCore.Mvc"": ""1.1.1"" } ``` After you have added direct dependencies to the fixed packages, save your `project.json` file. If you are using Visual Studio save your updated `project.json` file and Visual Studio will restore the new package versions. You can see the restore results by opening the Output Window (Ctrl+Alt+O) and changing the Show output from drop-down list to Package Manager. If you are not using Visual Studio open a command line and change to your project directory. Execute the `dotnet restore` command to restore your new dependencies. #### Using Visual Studio Solution Explorer (VS2017) If you want to use Solution Explorer, open your project in Visual Studio 2017, and then press Ctrl+; to activate the search in Solution Explorer. Search for each of the vulnerable package names and make a note of the version numbers of any results you find. For example, searching for `Microsoft.AspNetCore.Mvc.Core` in an example project that contains a package that takes a dependency on `Microsoft.AspNetCore.Mvc` shows the following results in Visual Studio 2017. ![vs2017](https://cloud.githubusercontent.com/assets/796298/25858816/8ecdc2b4-3491-11e7-9363-746804bb9832.png) The search results appear as a tree. In these results, you can see we have found references to `Microsoft.AspNetCore.Mvc.Core` version 1.1.2. Under the Dependencies node will be a NuGet node. Under the NuGet node will be the list of packages you have directly taken a dependency on and their versions. In this example, the application takes a direct dependency on `Microsoft.AspNetCore.Mvc`. `Microsoft.AspNetCore.Mvc` in turn has leaf nodes that list its dependencies and their versions. In the example the `Microsoft.AspNetCore.Mvc` package takes a dependency on a version of `Microsoft.AspNetCore.Mvc.ApiExplorer` which in turn takes a dependency on a vulnerable version of `Microsoft.AspNetCore.Mvc.Core`. #### Manually reviewing project.assets.json (VS2017) Open the `project.assets.json` file from your project’s obj directory in your editor. We suggest you use an editor that understands json and allows you to collapse and expand nodes to review this file; both Visual Studio and Visual Studio Code provide this functionality. Search the `project.assets.json` file for each of the vulnerable packages, using the format `AssemblyName/`. If you find any vulnerable assembly name in your search examine the line on which they are found, the version number is after the `/` and compare to the vulnerable versions table above. For example a search result that shows `Microsoft.AspNetCore.Mvc.Core/1.1.0` is a reference to v1.1.0 of `Microsoft.AspNetCore.Mvc.Core`. If your `project.assets.json` file includes references to any of the vulnerable packages shown above then you will need to fix the transitive dependencies. If you have not found any reference to any vulnerable packages this means none of your direct dependencies depend on any vulnerable packages or you have already fixed the problem by updating the direct dependencies. If your transitive dependency review found references to any of the vulnerable packages you must add a direct dependency to the updated package to your `csproj` file to override the transitive dependency. Open your `projectname.csproj` file in your editor, or right click on the project in Visual Studio 2017 and choose Edit `projectname.csproj` from the content menu, where `projectname` is the name of your project. Look for `PackageReference` nodes, for example: ``` xml netcoreapp1.1 $(PackageTargetFallback);portable-net45+win8+wp8+wpa81; ``` For each of the vulnerable packages your search returned you must add a direct dependency to the updated version by adding it to the `csproj` file. You do this by adding a new line to the dependencies section, referring the fixed version. For example, if your search showed a transitive reference to the vulnerable `System.Net.Security` version 4.3.0 you would add a reference to the appropriate fixed version, 4.3.1. ``` xml netcoreapp1.1 $(PackageTargetFallback);portable-net45+win8+wp8+wpa81; ``` After you have added the direct dependency reference, save your `csproj` file. If you are using Visual Studio, save your updated `csproj` file and Visual Studio will restore the new package versions. You can see the restore results by opening the Output Window (Ctrl+Alt+O) and changing the Show output from drop-down list to Package Manager.

What I'd like: ```c# var mergedItems = new HashSet(); foreach (var item in items) { mergedItems.GetOrAdd(item).RelatedInfo.Add(x); } public sealed class Item : IEquatable { public DateTime Date { get; } public int Amount { get; } public List RelatedInfo { get; } public bool Equals(Item other) => other != null && other.Date == Date && other.Amount == Amount; public override bool Equals(object obj) => obj is Item item && Equals(item); public override int GetHashCode() => // ... } ``` Today I'm forced to use a Dictionary which duplicates storage of the key for no reason. A dictionary is also wasteful because it has to do two hash lookups, one for `TryGetValue` and one for `Add`: ```c# var mergedItems = new Dictionary(); foreach (var item in items) { if (mergedItems.TryGetValue(item, out var otherItem)) mergedItems.Add(item, otherItem = item); otherItem.RelatedInfo.Add(x); } ``` This is no better; it's a lot more to maintain, unnecessarily coupled to the definition of equality, it's still duplicate storage of the key, and it's still duplicating the number of hash lookups: ```c# var mergedItems = new Dictionary<(DateTime, int), Item>(); foreach (var item in items) { if (mergedItems.TryGetValue((item.Date, item.Amount), out var otherItem)) mergedItems.Add((item.Date, item.Amount), otherItem = item); otherItem.RelatedInfo.Add(x); } ``` KeyedCollection is the worst of all because in addition to the dictionary, it keeps a list I'll never use. 19567 area-System.Security System.Security.Cryptography.Xml.Tests now at 0 failures on ILC.

It would great to have in v2.0 interfaces for most of what is coming in v3, v4, v5, v6 of .net core. For example all the generic collections, ot the IClonable or any other general utility apis, that you don't have time to implement in the current version i.e. v2.0. As this will help current nuget/plugin developers to code their classes to implement those interfaces, and weather you (.net team) or others implement them, its just a matter of injecting the implementation, instead of re-coding a lot of the project links/coupling, and it will eliminate the need that each developer implement his own interface for later linking them with others or his own implementation. As each interface done by different developers, even if it has the same functions, it will be considered different, because its from different assemblies.

These are the most commonly needed combinators, but there's another that's quite helpful, especially in tests: a combinatory that asynchronously waits for either all of the tasks to complete successfully or for the first one that doesn't complete successfully. This is particularly valuable when writing tests that involve related asynchronous operations, such as in networking, for example where you want to have an asynchronous client operation (e.g. socket.ConnectAsync) and an asynchronous server operation (e.g. socket.AcceptAsync) that are directly dependent on each other... using WhenAll can lead to deadlocks if one of those operations fails causing the other to wait forever. Proposal: ```C# public class Task { public static Task WhenAllSuccessfulOrAnyFailed(params Task[] tasks); public static Task WhenAllSuccessfulOrAnyFailed(IEnumerable tasks); ... } ``` From a behavioral standpoint, it would be as if code like this were used: ```C# var remaining = new List(tasks); while (remaining.Count > 0) { Task t = await Task.WhenAny(remaining).ConfigureAwait(false); remaining.Remove(t); t.GetAwaiter().GetResult(); } ``` but with a more efficient implementation.

This is sometimes known as ""Encoded-Word"" or ""Q-Encoding."" SMTP headers should also be limited in line length, and RFC-2047 sets a maximum line length of 76 characters. Therefore, when encoding unicode headers, it is typical to need to fold headers onto multiple lines. A common example might be something like the following: ```plain Subject: =?ISO-8859-1?B?SWYgeW91IGNhbiByZWFkIHRoaXMgeW8=?= =?ISO-8859-2?B?dSB1bmRlcnN0YW5kIHRoZSBleGFtcGxlLg==?= ``` It is really important to note that the base64 encoding in the above example uses two different character sets, this is not a particularly common example, but this is definitely legal. The binary data for an individual code point should never be split between two ""Encoded Words."" A more practical example is Unicode Emojis. Emojis frequently span multiple (and variable) bytes. In the case of UTF-8 individual code-points could be 1-4 bytes. Splitting emoji bytes on to multiple lines can result in the ""unicode block (�)"" appearing in some mail clients because the multi-byte characters are decoded separately. In other cases, spurious spaces are included. The current `Base64Stream` (and `QuotedPrintableStream`, it would seem) do not account for the byte boundaries of the encoded code points: https://github.com/dotnet/corefx/blob/master/src/System.Net.Mail/src/System/Net/Base64Stream.cs#L230-L246 At this level, the streams are (mostly) unaware of any text encoding semantics, and just write as many bytes as possible on each line. Instead, these encoding streams need to account for code-point byte boundaries, and fold the line preemptively, if only part of a code point can be included in the line before the next line fold would occur. I'm a little bit concerned that the stream is the wrong level of abstraction for this type of handling. Perhaps including some sort of ""look-ahead"" on the `WriteState` is a better option for determining the next smallest block of bytes that can be written is. I have a fork of Corefx and will be fixing it on my own.

But it's hanging on netfx. The problem is that ConnectStream.BeginRead on netfx first reads what it has buffered, and if it doesn't have buffered as much as was asked for, it then issues an asynchronous read rather than just returning what it has. This netfx behavior diverges from expectations around how Stream is meant to behave: Stream.Read/ReadAsync can block (asynchronously in the Async case) until there's any data available, but once there is data available they should return it rather than waiting arbitrarily long for more.

The current implementation exposes an event that is raised by the provider, and raises the `PropertyChanging` event passing an instance of type [`PropertyChangingEventArgs`](https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.propertychangingeventargs?view=netstandard-2.0) to the subscribing consumer. That however allows no interaction between the provider and consumer, since there is no way for the consumer to prevent the actual upcoming change. Among the things the consumer could potentially do is: - Throwing an exception, which is not necessarily caught by the provider or the change issuer up the tree - Cache the old value and compare it in the `PropertyChanged` handler (hoping it's the last handler). - Attach a `PropertyChanged` handler to try to set it back to previous value after all the 'changement' completed, again, relying it's the last handler in the chain. Anyway in both of the last options, the change will go back and force which might have a considerable performance impact and even heavy impact on UI (loading templates etc.). All of which are bad options, making the whole idea of `INotifyPropertyChanging` pretty much pointless. I mean, what point is there by knowing that a property is about to change without having any real option to do anything to prevent it or take control over it? [Here](http://stackoverflow.com/questions/8577207/better-propertychanged-and-propertychanging-event-handling)'s a sample discussion about this flaw. ### Solution To address this issue, I suggest that the `PropertyChangingEventArgs` class inherits from [`CancelEventArgs`](https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.canceleventargs?view=netstandard-2.0), this change is silent and unobtrusive, and it just introduces a new `Cancel` property, which the provider can then act accordingly. ### API changes Proposed change ([Line 13](https://github.com/dotnet/corefx/blob/master/src/System.ObjectModel/src/System/ComponentModel/PropertyChangingEventArgs.cs#L13)) ```c# namespace System.ComponentModel { - public class PropertyChangingEventArgs : EventArgs { } + public class PropertyChangingEventArgs : CancelEventArgs { } ... } ``` [Change](../commit/eea57d8206b36a70cca9c288ec3eacae55b2af43) ### Things to consider - Since the current implementation doesn't include the cancellation option, consumers using legacy `NotifyPropertyChanging`, have to know that that setting `Cancel` to `true` is not guaranteed to be obeyed by the provider - To address that, we can add an additional property defaulting to `false` called `IsCancellable`, which should be set to `true` by the provider using a dedicated constructor in the event-args, to make the intent of respecting the cancellation clear for both sides. - As @adampursley [commented](https://github.com/dotnet/corefx/issues/19627#issuecomment-330267649), it may be a good idea to include the old value and new value in both the `PropertyChangingEventArgs` and the `PropertyChangedEventArgs` to spare getting the value via reflection. For itself this might not be an issue, but here are some issues that we should consider: - Since legacy providers don't use the constructor providing the values, a consumer might think the new value is null. - That can be addressed as above, by adding another readonly property `IsCurrentValueSet` which is internally set by the event-args when using the constructor passing values as parameters. - This will require boxing and unboxing for each raised event for value-typed properties (which are IMHO most of the NPC entity properties), and not necessarily the consumer is always interested in knowing the value, especially in post-change, where consumers usually only want to get notified about a change, not caring what the data actually is. - Both in pre-changing and post-changing, the value can be acquired with reflection, in standard implementation, `sender` (in the [`PropertyChangingEventHandler`](https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.propertychangingeventhandler?view=netstandard-2.0)) is usually the instance containing the provided property name. 19629 area-Serialization DCS_ResolveNameReturnsEmptyNamespace Failed on UWP "`DataContractSerializerTests.DCS_ResolveNameReturnsEmptyNamespace` failed on UWP. ```xml members) in

The 2.0 pipelines use Jenkins new pipeline job functionality to make the build/test process clearer and map much closer to official processes. Pipelines also have the advantage of being easier to edit in a PR. There are two types of files in this PR. * The pipelinejobs.groovy file is a type of netci.groovy file which identifies the pipelines that need to be run, their triggers and the parameters that run on each trigger. It has a simpler form with far fewer options than netci.groovy * The portable-windows.groovy and portable-linux.groovy files are the pipelines themselves. The Linux pipeline uses docker to build the product, then sends off to Helix for testing. Links to helix test results are linked to on the GitHub PR. Windows pipelines build natively on Windows, and again submit off to Helix for testing. These pipelines are currently not enabled by default until we are sure they are valid (also there are currently failures in some tests), but can be launched with: * @dotnet-bot test portable linux debug pipeline * @dotnet-bot test portable linux release pipeline * @dotnet-bot test portable windows debug pipeline * @dotnet-bot test portable windows release pipeline There are clearly a number of additional improvements that need to be made: * Pipelines need to be expanded to x86, arm, arm64, etc. * Pipelines to be expanded to commits (works today but has a couple issues with reporting) * May need to tweak logic used to generate links to Mission Control in non-PR cases.

In netstandard 2.0, the method DbProviderFactory.CreateDataAdapter() is present, however this method isn't implemented in SqlClient.SqlClientFactory, leading to a null being returned. This is likely an oversight caused by the fact that the factory was ported over way before DataTable and friends were ported over.

Filing because this is the wall I'm hitting at the moment. 19709 area-System.Net Proposal: HttpClientHandler.DangerousAcceptAnyServerCertificateValidator property We have what in my mind is a big problem with HttpClient in 2.0: to use HttpClient with self-signed certs (very common in testing environments), you need to hook up a ServerCertificateCustomValidationCallback; that will override the default verification and can be made to always return true. We do this in all of our HTTP testing in corefx, ASP.NET did it in theirs, etc. Unfortunately, this doesn't work on macOS nor on several Linux distros. The problem is that libcurl only supports the necessary callbacks to enable this when using an OpenSSL backend, and if such a backend isn't in use, we can't enable this delegate callback and thus throw a PlatformNotSupportedException when trying to hook up the delegate. As it stands today, basically none of our https testing for HttpClient is running on macOS/CentOS/RHEL/Fedora, ASP.NET recently had to switch away from HttpClient for their testing because of this, etc. ~~Proposal: We add the following property to HttpClientHandler: public class HttpClientHandler { public bool ValidateServerCertificate { get; set; } = true; ... } The default behavior is as things are today. But if you set ValidateServerCertificate to false, we disable verification, both built-in and custom via the callback. We should be able to do that on all Unix's via libcurl's https://curl.haxx.se/libcurl/c/CURLOPT_SSL_VERIFYPEER.html, and we can do so on Windows simply by substituting a `delegate { return true; }` delegate (or tweak a setting if there is one).~~ Updated proposal (5/13/2017): We add the following property to HttpClientHandler: ```C# public class HttpClientHandler { public static Func DangerousAcceptAllCertificatesValidator { get; } = delegate { return true; }; ... } ``` A developer can use this delegate with ```C# handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAllCertificatesValidator; ``` For platforms that already support the callback, nothing need change, although they could be optimized to specially recognize this delegate instance to avoid the callback needing to be invoked. For platforms that don't support the callback, we can use object equality to check for this delegate instance: if any other instance is supplied, we continue to throw a PNSE, but if this instance is supplied, we flip the appropriate options so that certificates are not validated and all are accepted. cc: @bartonjs, @davidsh, @cesarbs, @CIPop 19710 area-System.IO Directory.Move no longer moves files "The following works fine with net45 and netcoreapp1.0, throws a `DirectoryNotFoundException` with 2.0. ``` File.Create(""test.txt"").Dispose(); Directory.Move(""test.txt"", ""test2.txt""); ``` " 19712 area-System.Data netstandard2.0: SqlParameter's decimals are coming back with integer precision (SqlClient issue) "I came across this when [updating Dapper to `netstandard2.0`](https://github.com/StackExchange/Dapper/commit/7e5bd308f99b790212e6990bc4ec8b0c72579406).

However if we don't submit the request and only do: ```cs HttpWebRequest request = HttpWebRequest.CreateHttp(url); request.BeginGetRequestStream(null, null); ``` Both platforms will throw a `ProtocolViolationException`. This is because in .Net Core we are checking first if the request was submitted, and in Desktop the first thing we do is checking if the current protocol is valid. #### Netcore http://source.dot.net/#System.Net.Requests/System/Net/HttpWebRequest.cs,1026 #### Desktop https://referencesource.microsoft.com/#System/net/System/Net/HttpWebRequest.cs,1515 However if we want to match behaviors by doing the protocol first in [.NET Core](http://source.dot.net/#System.Net.Requests/System/Net/HttpWebRequest.cs,1034) to match Desktop's behavior we would be introducing a breaking change because we already shipped this behavior in 1.1 and 1.0 Which one we care most, being compatible with Desktop or with core previous versions? cc: @stephentoub @davidsh @ViktorHofer 19733 area-Serialization Fix several codegen issues 1.

The intent is to only put SerializableAttribute on types where: 1. The types can be correctly serialized between runtimes, versions, and operating systems. This was determined by looking at types that have runtime or OS dependencies or are highly subject to change. 2. The types are clearly important for users to create their own serializable types. This was determined by analyzing serialization usage data along with adding types that complete sets or are needed in order to serialize other types. In all, about 100 types will continue to be serializable by BinaryFormatter. Of course, it's possible we've excluded an important type. We have chosen to start with a conservative set, but to expand it as necessary based on user feedback. This change removes SerializableAttribute from the CoreFX types that didn't make the list as well as removing testing for serializing those types. Future changes will include: * Making similar sweeps through CoreCLR and CoreRT * Changes to make serializing these types compatible where their serialized form doesn't match .NET Framework. 19743 area-System.Data Possible bug in System.Data.SqlClient, with LocalDB and Stored Procedures "While porting some code from .Net 4.5 to core, I noticed a possible bug and currently see no workaround.

The way ADO.NET is setup, `DbDataReader` has added some methods over time (since adding to interfaces is bad), of these `.GetSchemaTable()` is one brought back in `netstandard2.0`. It's a virtual that each implementation needs to override. [Here's the Core FX `DbDataReader.GetSchemaTable()`](https://github.com/dotnet/corefx/blob/master/src/System.Data.Common/src/System/Data/Common/DbDataReader.cs#L57): ```c# public virtual DataTable GetSchemaTable() { throw new NotSupportedException(); } ``` The problem is [`SqlDataReader` never overrides this](https://github.com/dotnet/corefx/blob/84d5d7e278249a8c3682801a05ff505cd489ebb1/src/System.Data.SqlClient/src/System/Data/SqlClient/SqlDataReader.cs). For comparison, here's reference source for .NET 4.x [where this does happen](https://referencesource.microsoft.com/#System.Data/System/Data/SqlClient/SqlDataReader.cs,1396). In the current state, the result is a `NotSupportedException` when actually calling the method: ``` System.NotSupportedException : Specified method is not supported. Stack Trace: at System.Data.Common.DbDataReader.GetSchemaTable() at System.Data.ProviderBase.SchemaMapping..ctor(DataAdapter adapter, DataSet dataset, DataTable datatable, DataReaderContainer dataReader, Boolean keyInfo, SchemaType schemaType, String sourceTableName, Boolean gettingData, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.FillMappingInternal(DataSet dataset, DataTable datatable, String srcTable, DataReaderContainer dataReader, Int32 schemaCount, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.FillMapping(DataSet dataset, DataTable datatable, String srcTable, DataReaderContainer dataReader, Int32 schemaCount, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.FillFromReader(DataSet dataset, DataTable datatable, String srcTable, DataReaderContainer dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DataAdapter.Fill(DataTable[] dataTables, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.DataTable.Load(IDataReader reader, LoadOption loadOption, FillErrorEventHandler errorHandler) at System.Data.DataTable.Load(IDataReader reader) ``` Note that this wasn't calling it directly, it was trying to use `DataTable` much further away. So there's quite a few places this is used. I think this was just an oversight after `DataTable` and truckloads of other things were brought back for `netstandard2.0`. Can we please get this in so it's usable? Past issues for context on more usages (for prioritization): - #1039 - #3423 Related concern: this isn't listed in #17126 because it compiles and doesn't have a `PlatformNotSupportedException`, but it's obviously missing. I think we need a separate API call for ADO.NET for things that aren't overridden in CoreFX, that's the superset of items we need to narrow down and fill the gaps on. Not everything should be overridden, but that's likely the easiest list to generate and quickly narrow down. 19749 area-System.Data Scan SqlClient for missing overrides and interface implementations We got 2 reports on .NET Core 2.0 Preview 1 which point to a class of problems we missed: * #19712 - Missing interface implementation `System.Data.SqlClient.SqlParameter : IDbDataParameter` (fixed in PR #19734) (reported by @NickCraver) * #19748 - Missing override `System.Data.SqlClient.SqlDataReader.GetSchemaTable` (reported by @NickCraver) * #19651 & #19673 - Missing override `System.Data.SqlClient.SqlClientFactory.CreateDataAdapter` (fixed in PR #19682 by @justinvp) (reported by @RickStrahl & @FransBouma) I think we need to boost our compat tooling, identify all missing overrides and interface (re)implementations and review all instances. We should probably think deeply if we are missing any other problem classes - we had a list of things we didn't scan for, so maybe we should review it carefully again?

For example, create a .NET Core Console application with the following code: ```c# using System; using System.Runtime.CompilerServices; namespace ConsoleApp { class Program { static void Main(string[] args) { object key = new object(); while (true) { var table = new ConditionalWeakTable>(); table.Add(key, new Tuple(table, new byte[1000000])); GC.Collect(); } } } } ``` Expected behavior: The memory consumption of the program should stay in the same area, because when a new `ConditionalWeakTable` instance is created, there are no more references to the previous `ConditionalWeakTable` and its `Tuple` value, so they should be able to be reclaimed by the Garbage Collector. Actual behavior: The memory consumption rises rapidly (4 GB after some seconds) until an `OutOfMemoryException` is thrown, as the byte arrays are not reclaimed by the garbage collector. However, if you remove the reference to the table by replacing `table.Add(...)` with `table.Add(key, new Tuple(null, new byte[1000000]))`, the problem disappears. If the algorithm cannot be implemented such that it can detect that there are no more references to the table and its values, I think the `ConditionalWeakTable` should implement a `Dispose()` method that allows to clear all key-value-pairs. The behavior is the same for .NET Core (.NETCoreAPP 1.1) and .NET Framework 4.6.2.

//equivalent to m.M11 ``` This is mainly convenience, but become big one if one want to get matrix property ""randomly"" e.g. in `for` loop. In this case one must write pretty big `if` `else` block or `switch`. `ref` might be useful to be able to send matrixes to graphic libraries efficiently and conveniently. Next use case is migrating between vector libraries that support indexers (like `OpenTk`) Note: `ref` returning indexer shouldnt be problem there because omitting `ref` when calling means automatic dereference so in theory one could just change `using` and recomplie without problems (assuming no issues with world coordinates etc.) Since `ref` and `out` alternative methods got postponed, i think patch with them is perfect to include ref indexers as well unless you want to backport them to ealier versions of c# than 7 EDIT: If you decide to implement ref indexer without changing internal representation, i think it could be implemented using `Unsafe.Add`. Something along these lines: ```c# public ref float this[int row,int col]{ get{ if(row<0 || row>3 || col<0 || col>3) throw new IndexOutOfRangeException(); var index=0; if(row is 1) index=4; else if(row is 2) index=8; else if(row is 3) index=12; index+=col; return ref Unsafe.Add(ref this.M11,index ); } } ``` EDIT 2: With spans available, you could implement indexers for retrieving only row or only column (return 4-elements span which is constructed using `DangerousCreate(this, ref this.MdesiredRow0, 4)`, Column is more tricky and probably would be implemented as tuple or float[4] since column arent layed out in continguous blocks, unless you add 'jumping' every X elements support to spans. Or just return span over whole matrix and force users to deal with 'jumping') " 19771 area-System.Data Port DatasetExtensions to .NET Core Anyones knows if .AsEnumerable() propertie will be available for datatable on .net core 19773 area-System.Runtime Unload assembly from runtime Hello, Now that AppDomains have been removed from .NET Core, how does one unload an assembly from memory once it has been loaded?

We are finishing support in stack traces for portable and embedded PDBs for 4.7.1. Features that generate code at runtime (such as scripting) would benefit from being able to detect whether the runtime supports Portable PDBs or not, as they could emit Portable PDBs instead of Windows PDBs. Emitting Portable PDBs has perf benefits. In order to make the feature detection consistent across all platforms we propose to add the following APIs to netstandard as well. # Proposed API ```C# namespace System.Runtime.CompilerServices { public static class RuntimeFeature { public const string PortablePdb = nameof(PortablePdb); // returns true for feature == ""PortablePdb"" public static bool IsSupported(string feature); } } // Usage if (RuntimeFeature.IsSupported(""PortablePdb"") { // Emit code with Portable debug info } ```" 19789 area-System.Reflection Need Reflection api to enumerate type-forwards in an assembly. **Proposed Api** ```c# class Assembly { public virtual Type[] GetForwardedTypes() { throw new NotImplemented.ByDesign; } } ``` Gets the Types exposed by this assembly but defined in another assembly. If one or more Types fail to load (perhaps because the forwardee assembly cannot be found), this api throws a **ReflectionTypeLoadException**. The **ReflectionTypeLoadException**'s **Types** and **LoaderExceptions** property can be queried to recover the Types that did successfully load. (Works similarly to **Assembly.GetTypes()** (https://msdn.microsoft.com/en-us/library/system.reflection.assembly.gettypes(v=vs.110).aspx)) **Why is the api signature so retro?** This is a companion api to **Assembly.GetTypes()** and follows its form. We could also have used **Assembly.DefinedTypes** as a template but that form has two problems: - That api was introduced for the aborted .Net Core 1.0 refactoring and returns **TypeInfo** rather than **Type**. **TypeInfo** is now a historical curiosity and an unnecessary distraction. **Assembly.GetTypes()** has the incumbency advantage. - The **IEnumerable** form is intended to imply lazy list generation which is at odds with the **ReflectionTypeLoadException** mechanism of salvaging partial results in the event of type load exceptions. The docs are silent as to whether you can recover partial results with this form. **Use case** This was always a functionality hole in Reflection and in this world of refactoring-happy .Net Core, type forwarders are everywhere, even in reference assemblies. We've already had one issue raised about this (https://github.com/dotnet/corefx/issues/19713) as it used to be possible to enumerate System.Xml's surface area with Reflection but no longer. **Nested Types** The returned array will include any nested types within returned types whose visibility (and that of its containing nested types) is **NestedPublic**. This reflects the ECMA-335 rule that the ExportedTypes table can only contain types that are **Public** or **NestedPublic**. Nested types will be returned whether or not the ExportedType table contains a separate entry for the nested type (as the presence or absence of it has no effect on whether the nested type can be resolved through that assembly.) **AssemblyBuilder** AssemblyBuilder does not override GetTypes() and there's no burning reason to override GetForwardedTypes() either. It's not like you can add type forwards using RefEmit today. 19791 area-System.Net Fix SendAsync on Unix with multiple buffers In the implementation of Send{To}Async for a list of array segments, we try to do the send operation synchronously, and if it doesn't send the full amount (e.g. because it does one send that's less than the full amount and then tries to complete it but gets an EAGAIN), we then fall back to creating a SendOperation that stores the data to try again later with the remainder. But the number of bytes sent in that initial set of operations wasn't being copied into that SendOperation data structure, so although the data had been sent and although we were correctly updating the pointers to what to send next and when we were done sending, the actual total number of BytesTransferred at the end of the operation would be missing the sum from that initial successful set of synchronous sends prior to the EAGAIN. The fix is simply to store the initial bytesSent into BytesTransferred, as is done for every other send operation on SocketAsyncContext. I also added an explicit test for this, rather than relying on modifying our perf tests to catch it.

This did not throw any exception when the underlying array is null, so `ToArray()` would return an empty array. Now that ArraySegment has its own `ToArray()` function, my code is calling that one (with no code change on my part). `ArraySegment.ToArray()` throws an exception when called with a null underlying array. I can work around this, but is this considered a breaking change? _Copied from original issue: dotnet/corert#3619_ 19803 area-System.Xml Change DefaultResolver in XmlReaderSettings to XmlUrlResolver Addresses a behavior difference between Core and Desktop.

I didn't remove any members but I had to rename some as these files use different code styles (internal fields) and Odbc and Common used to use `Hashtable `instead of `Dictionary` for 'synonyms' (like SqlClient does). It's needed to make mono happy. Probably would be better to just move DbConnectionOptions.cs to Common without splitting it to provider-specific pieces - they are not too big and the ILLINK will remove unused code anyway. 19809 area-Serialization [UWP] XElement Tests Failed "The following tests failed on UWP.

List already covers this scenario, resizing array behind the scenes. Proposal is to add a method that returns a correctly sized Span window over the List's array. i.e. A non allocating version of `.ToArray()` that's also better as it can be made immutable with ReadOnlySpan. /cc @jkotas @terrajobst @stephentoub @davidfowl 19817 area-System.Runtime Proposal: dynamic array with lazy reallocation feature "Copied from https://github.com/dotnet/csharplang/issues/586 The current C# array can ""resize"", but it acturally allocates new memory and copies data, and the old memory can neither be freed nor be used until next GC. I hope to have a kind of dynamic array which can change its length without memory reallocation until next GC. When this kind of array extend its length, only allocate memory of ""extended"" size, and use an internal list to manage the old and new memory. Users needn't know how many internal fragments the dynamic array has, they should be able to use it as a normal array. When GC occurs, the CLR should put all fragments of a dynamic array together and update internal link pointers. If the dynamic array reduces its length, the CLR should be able to ""free"" some memory after next GC. All these CLR actions should be transparent to users. The dynamic array should be a new class, and do not affect the behavior of the current array. For example: ```C# DynamicArray da=new DynamicArray(100); //length is initialized to be 100 ...... da.Resize(200); /*new size is 200, but only allocate new memory of size 100. Old memory is still in use and links to new memory. Now 'da' has internal fragments, but it will have contiguous memory of size 200 after next GC. */ ...... da.Resize(10); /* No allocation.

On Desktop/.NET full this is used by `DbConnection.ProviderFactory`, an internal property used by `DbProviderFactories`. This last class isn't part of .NET core, however the lack of these properties and implementation makes it harder to bring this class back to .NET core, as `DbProviderFactories` contains a method `GetFactory(DbConnection)`, which simply reads the property `DbConnection.ProviderFactory`. Likely a complete oversight due to the stalemate on whatever has to happen with DbProviderFactories in .NET core for the last 2 years (See #4571 ) My advice would be two-fold: * add `DbConnection.ProviderFactory` property, as internal. (See: https://referencesource.microsoft.com/#System.Data/System/Data/Common/DBConnection.cs,68) (will file another issue for that) * override `DbConnection.DbProviderFactory` in SqlConnection.cs. This would then open the door to add `DbProviderFactories` to .NET core to make sharing code using that class between .NET full and .NET core easy. 19826 area-System.Data DbConnection doesn't offer an internal property ProviderFactory Hi (This issue is related to #19825). To bring back the functionality of the `DbProviderFactories` class to .NET core so sharing of code between .NET full and .NET core is easy, it's required to have `DbConnection.ProviderFactory` present, as `DbProviderFactories` has a method `GetFactory(DbConnection)` which reads this property to obtain the factory. .NET full has this implementation: https://referencesource.microsoft.com/#System.Data/System/Data/Common/DBConnection.cs,68 which reads the virtual property `DbProviderFactory` which is present in .NET core's DbConnection (and by default returns null). Implementing this property on DbConnection will make it easy to add the `DbProviderFactories` class from reference source to .NET core (without the machine.config stuff of course) and offer the same functionality so porting code over from .NET full to .NET core is easy. 19827 area-System.Net [HttpListener] Multiple HttpListeners on same IP Endpoint "In both .NET 4.5 and Mono, you could have have `HttpListener` instances listen on the same IP Endpoint with different paths, such as for instance HttpListener listener1 = new HttpListener (); listener1.Prefixes.Add (""http://127.0.0.1:"" + port + ""/""); HttpListener listener2 = new HttpListener (); listener2.Prefixes.Add (""http://127.0.0.1:"" + port + ""/hola/""); listener1.Start (); listener2.Start (); This behavior has changed in https://github.com/dotnet/corefx/commit/7a48e11efae5b163a6c3b3d49a7066960e40a5c2 with no explanation why this change has happened. It is a problem for two reasons: 1. It changes behavior from .NET 4.5 in a way that could possibly break many existing customer applications. 2. It shifts the burden of maintaining endpoint listeners from the backend to the user. I discovered this problem while trying to replace Mono's HttpListener implementation with the one from CoreFX (see https://github.com/mono/mono/pull/4850). Since this change could possibly break an unknown amount of existing customer code (apart from our failing unit test), it currently blocks us on going forward with the change.

Issues #19227, #18202 19843 area-Serialization Enabled XmlSerializer to Serialize XElement on UWP. After PR https://github.com/dotnet/corefx/pull/19244, `XmlSerializer` failed to serialize `XElement` on UWP because the metadata info for `XElement..ctor()` was reduced by UWP toolchain. Although we already have rd.xml for keeping the constructor, see [System.Private.Xml.Linq.rd.xml](https://github.com/dotnet/corefx/blob/87a72facb51c0b50489223f1ef2e52195e1a3f00/src/System.Private.Xml.Linq/src/Resources/System.Private.Xml.Linq.rd.xml), it didn't work because the assembly has `BlockReflectionAttribute` and UWP toolchain would remove metadata for any non-public types/members in the assembly. The fix is to make the constructor public on `uap`. Fix #19809. 19844 area-System.Security Make all X509Store.Open exceptions be CryptographicException. The platform limitations are now CryptographicException(PlatformNotSupportedException) instead of PNSE. This should restore some user expectation around the exception model, given that the call to Open can be delayed from the call to an X509Store .ctor. This also softens the exceptions from the Disallowed store on Linux to let empty reads succeed, only writes and pre-populated data will fail.

When that rule was decided, the C# compiler was only emitting `call` IL instruction in a couple places that didn't really matter and used the IL `callvirt` for everything else (even if the destination instance method was non-virtual, because per the C# spec, calling instance methods with a null `this` needs to throw and `call` IL instruction won't throw). This made it unlikely that people would hit problems with it. The addition of the null-propagation operator gave the C# compiler more opportunities to optimize `callvirt` into a `call` if the `this` is known to be not null. dotnet/corert#3565 has an example where making a member virtual resulted in wrong method being called when compiling against PCL contracts because a breaking change was made making `ConstructorInfo.Invoke` virtual: ```csharp var abc = (ABC) constr.Invoke(new object[0]); // This works ``` ```csharp var abc = (ABC) constr?.Invoke(new object[0]); // This calls the wrong method because // `this` is known not to be null and Invoke // is a non-virtual method ``` Making a member virtual is a breaking change for anyone using the null-propagation operator with the method. 19862 area-Serialization Use stream as the input of GenerateSerializer method Fix #19859 @shmao @mconnew @zhenlan 19864 area-System.Data Adding GetSchemaTable() on SqlDataReader Porting over code to add GetSchemaTable in .Net Core SqlClient.

This revert causes test failures in Add_PrefixAlreadyRegisteredAndNotStarted_ThrowsHttpListenerException The second commit adds a swathe of tests for various scenarios. Most of these tests failed before the revert. It turns out the fix to the difference in behaviour between managed and Windows is actually as simple as removing an `if` in HttpEndPointListener.AddPrefix. Previously the managed implementation wouldn't throw if we tried to add the same prefix with the same listener - but it would with different listeners. Instead we should always throw, in order to match Windows behaviour.

This way it's easier to bring back DbProviderFactories from .net full. The code was removed in commit 8150669, associated with issue #17905. cc @karelz @saurabh500 (edit). This PR tracks now also the implementation of #4571. The public API is as follows: ```cs public static partial class DbProviderFactories { public static DbProviderFactory GetFactory(string providerInvariantName) public static DbProviderFactory GetFactory(DataRow providerRow) public static DbProviderFactory GetFactory(DbConnection connection) public static void SetFactory(string name="""", string providerInvariantName="""", string description = """") where TFactory : DbProviderFactory public static void SetFactory(DbConnection connection, string name="""", string providerInvariantName = """", string description = """") public static DataTable GetFactoryClasses() } ``` The public API of the NetFX DbProviderFactories class is the same as the public API of this class. Differences: - It doesn't auto-initialize itself, by default no factory/providers are registered. - It can be manipulated using a public API at runtime. Usage to register a factory: ```cs DbProviderFactories.SetFactory(); // or DbProviderFactories.SetFactory(new SqlConnection()); ``` The method accepts more parameters, so the developer can specify their own InvariantName, name and description if they want to. If they're not supplied, like the example above, they're obtained from the Type.

In addition to the automatically identified cross-platform warnings, identify what things which were brought back that should just be generally regarded as deprecated and add them to the code analyzer tooling. In addition to those items, some 1.x API should be tagged: * The Windows CAPI dependencies (*CryptoServiceProvider types) * Already tagged for cross-platform risk, but should be tagged as well for deprecation. * The Rfc2898DeriveBytes ctors that do not take HashAlgorithmName as an input * Potentially others. 19888 area-System.Security X509Certificate2.CopyWithPrivateKey does not work as expected.

Because of this issue, `certificate1` cannot be used for `SslStream.AuthenticateAsServer` method.

To my knowledge, in order to extract a zip file and overwrite the contents - since `ExtractToDirectory` doesn't have that ability yet (#8146!) - the following is the smallest way of performing this: $zip = [System.IO.Compression.ZipFile]::OpenRead(""MyCompressedFile.zip"") foreach ($item in $zip.Entries) { if ($item.FullName.EndsWith(""/"") -and $item.name -eq """") { (New-Item $item.FullName -type directory -force) > $null } else { ([System.IO.Compression.ZipFileExtensions]::ExtractToFile($item, (Join-Path -Path $pathToExtractDirectory -ChildPath $item.FullName), $true)) > $null } } As you can see on the third line, we need to determine whether the `ZipArchiveEntry` is a directory or file - `$item.FullName.EndsWith(""/"") -and $item.name -eq """"`. If this condition can be changed to `$item.IsDirectory` or `$item.IsFile` then I believe that this would make it easier for developers to extract files in this way. The function of the `IsDirectory` property is simply to provide a shorthand, user-friendly mechanism of succinctly determining the object type of the `ZipArchiveEntry`. It could also be an enum, such as `ZipArchiveEntryType`, but I believe that this might be overkill." 19890 area-Infrastructure VS Code has trouble opening projects from CoreFX I've been trying to use VS code for CoreFx development, but with very little luck so far. First of all there doesn't seem to be a master solution, some assemblies have their own solutions some don't, there doesn't seem to be much of an order in the .sln files. Opening the repo in VS Code, one needs to pick the .sln to work with (so that OmniSharp has a way to load the projects). Just two examples: - System.Threading.tasks.sln - there are several warnings and failures reported when opening this. The end result is that intellisense doesn't work at all - no Go to Definition or anything like that. - System.Private.Xml.sln - this one seems to open without fatal errors, so some of the intellisense lights up, but then the IDE reports a huge number of errors. Opening a random source file like XmlResolver.cs shows a lot of red squiggles. Basically it seems that types from CoreLib don't resolve at all. 19892 area-Infrastructure Confirm stability of new Perf.Environment tests We checked in new tests in this PR, https://github.com/dotnet/corefx/pull/19623.

But what can we use within tests where we have different behaviors between platforms? For example, we have the `PlatformDectection` class. We can use things like ""if (PlatformDetection.IsFullFramework)"" etc. However, for UAP apps, it is confusing. We have PlatformDetection.IsWinRT. That seems to do a runtime check on the exe itself to determine if it is app-container, etc. But I've heard that uap-aot testing doesn't actually run as app-container. It is a synthentic ILC.EXE conversion of the managed test assembly creating a native console win32 app. So, `IsWinRT` would work in uap test runs (UWP F5) but not uap-aot test runs (UWP ILC). We also have PlatformDetection.IsNotOneCoreUap but that seems to check for the existence of httpapi.sys which is weird....that really is a SKU check and not a runtime check of the type of the application. We need a PlatformDetection.IsUAP that works reliably for UAP or UAP-AOT test runs. Do we have something to address this? cc: @weshaggard @AlexGhiondea @danmosemsft @stephentoub " 19908 area-System.Net Add DangerousAcceptAnyServerCertificateValidator property to HttpClient It's a common pattern in certain situations (in particular in tests) to use HttpClient to connect to a server with a certificate that shouldn't be validated, e.g. a self-signed cert. This is commonly achieved with HttpClientHandler by setting the ServerCertificateCustomValidationCallback property to a delegate that always returns true (returning true means that the cert passed validation): ```C# handler.ServerCertificateCustomValidationCallback = delegate { return true; }; ``` However, we can't support this callback on all implementations of HttpClientHandler. For example, on macOS, the default libcurl built against SecureTransport doesn't provide the callback we'd need to properly implement the callback, and as such, today trying to set up such a callback results in a PlatformNotSupportedException. This blocks some important scenarios; that includes testing (e.g. ASP.NET had to move away from HttpClient because of this, https://github.com/aspnet/MetaPackages/pull/100) but also higher level libraries and tools that provide similar functionality (e.g. PowerShell's `Invoke-WebRequest -SkipCertificateCheck` is blocked by this https://github.com/PowerShell/PowerShell/issues/3648). This PR adds an approved API to address this case: ```C# public static Func DangerousAcceptAnyServerCertificateValidator { get; } ``` The actual implementation of this property is trivial, simply returning a cached always-return-true delegate: ```C# public static Func DangerousAcceptAnyServerCertificateValidator { get; } = delegate { return true; }; ``` so developers can just substitute it for their custom delegate: ```C# handler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator; ``` The benefit of that is it gives HttpClientHandler implementations a known object reference identity that can be compared against to understand the developer's intention: if the object stored in ServerCertificateCustomValidationCallback is reference equals to DangerousAcceptAnyServerCertificateValidator, then we know that it will always return true, and on platforms where we'd otherwise throw a PlatformNotSupportedException because we can't hook up a callback, we can still entirely disable validation. This enables such scenarios to work. (As a side benefit, such a property means developers can use this property and give tools an easier opportunity for flagging the danger of such disabling of validation, making it easier for developers to avoid shipping insecure applications.) This PR: - Adds the property and the singleton delegate implementation. - Adds some tests to ensure it behaves correctly. - On Unix, if we would throw a PNSE because a callback was supplied, we special-case DangerousAcceptAnyServerCertificateValidator to avoid throwing. No changes were made to the implementation on Windows. In the future, we could choose to go further and avoid hooking up the delegate at all on both Windows and Unix even if callbacks are supported, as doing so may save some overhead. However, as this is not meant to be a common case in production, I've only modified code necessary to get these scenarios working.

The comments in the code suggest this worked properly at one time, but there was no test guaranteeing functionality. This change handles the null return from GetPrivateKeyCsp, and adds some tests to ensure this doesn't break again.

Instead, the Windows error mode should be set once in the host during startup if applicable.

By making the API determine if a file is an assembly and returning the name we avoid having to open the file twice. The other alternative available today requires using System.Reflection.Metadata which is not part of netstandard and requires redistributing a sizeable dependency (800KB), or writing your own PE parsing code (which requires opening the file twice). /cc @gkhanna79 19929 area-System.Security System.Security.PermissionSet im getting the following error System.TypeLoadException: 'Could not load type 'System.Security.PermissionSet' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.'

Not able to repro locally, want to get more info from CI 19949 area-Infrastructure Avoid having runtime specific assets when they aren't necessary. Due to an issue in nuget which will hopefully be address with https://github.com/NuGet/Home/issues/5192 some of our packages end up with the wrong asset being selected when we have both runtime and lib assets in the package. For some of our packages that isn't necessary. Example: System.Security.Permissions has a runtime\net461 asset and a lib\netstandard2.0 asset and when a netcoreapp2.0 project has a fallback of net461 we will prefer the net461 asset over the netstandard2.0 asset which will not work on netcoreapp2.0. See https://github.com/dotnet/corefx/issues/19929. We should do an audit of other packages in this situation to avoid it. 19952 area-System.Net Fix some Http tests for UAP Fixed some of the HttpRequestMessage tests for UAP. HttpRequestMessage has a different default value for the Version field on UAP platforms compared to netcore or netfx. Added PlatformDetection.IsUap to support this. Implementation of this property was based on investigations for #19907. This property is true on both 'uap' and 'uap-aot' platforms.

PR in master https://github.com/dotnet/corefx/pull/19905 Fixes: #19708 19963 area-System.Net HttpClient WebRequestHandler.CachePolicy Replacement I've run the Portability Analyzer and found that HttpClient does not implement WebRequestHandler.CachePolicy and I don't seem to be able to find any replacement for this. @karelz suggested asking here. A [similar question](http://stackoverflow.com/questions/43272530/whats-the-alternative-to-webrequesthandler-in-net-core) was asked on Stack Overflow and has no answer. I would like to know if there is any equivalent to WebRequestHandler.CachePolicy in .NET Core for use with HttpClient. If there is no equivalent, I would like to know what the effective equivalent default value is in .NET Core? More specifically, .NET Core's implementation is equivalent to a RequestCacheLevel of BypassCache OR CacheOnly OR CacheIfAvailable OR Revalidate OR Reload OR NoCacheNoStore? Furthermore, is it consistent across platforms? From examining the [source](https://github.com/dotnet/corefx/tree/master/src/System.Net.Http/src/System/Net/Http), I think it might be BypassCache, but I'm not sure and would like confirmation. I'm also unsure if an OS level cache is used on Windows or elsewhere or whether .NET Core bypasses those. If BypassCache is not the current equivalent default on .NET Core or if any intermediate caches such as OS caches are being used on any platform, I think there needs to be the option to set BypassCache, so we're able to implement our own caching on top of HttpClient. 19964 area-System.Net NoCallback_RevokedCertificate_NoRevocationChecking_Succeeds failed with System.Net.Http.CurlException : Problem with the SSL CA cert (path? access rights?) again https://mc.dot.net/#/user/mmitche/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fportable~2Fcli~2F//workItem/System.Net.Http.Functional.Tests/analysis/xunit/System.Net.Http.Functional.Tests.HttpClientHandler_ServerCertificates_Test~2FNoCallback_RevokedCertificate_NoRevocationChecking_Succeeds ``` nhandled Exception of Type System.Net.Http.HttpRequestException Message : System.Net.Http.HttpRequestException : An error occurred while sending the request.\n---- System.Net.Http.CurlException : Problem with the SSL CA cert (path? access rights?)

Allowed names are: {string.Join("", "", names)}."" ``` This has two problems: 1. It's verbose (even has nested quotes) 2. It allocates extra string for the result of Join (potentially large) I would like to propose a custom format specifier instead (name is up for consideration): ``` $""Name not found. Allowed names are: {names:J', '}."" ``` And for lists of formattables (saves N+1 allocations instead of 1): ``` $""Byte is incorrect. Allowed bytes are: {string.Join("", "", bytes.Select(b => b.ToString(""X2"")))}"" // could become $""Byte is incorrect. Allowed bytes are: {bytes:J', ':X2}."" ```" 19988 area-System.Diagnostics Fix Process.Start() on Unix platforms to not leak file descriptors of redirection pipes to child processes Fix #13447. Summary of the issue: ------------------------ When an application starts more than one child processes with their standard inputs redirected on Unix, closing the standard input stream of the first child process won't unblock the 'Console.ReadLine()' call in the first child process (it's expected to receive EOF). Root cause of the issue: -------------------------- The file descriptor for the write end of the first child process standard input redirection pipe gets inherited by the second child process, which makes the reference count of the pipe write end become 2. When closing the standard input stream of the first child process, the file descriptor held by the parent process is released, but the one inherited by the second child process is still referencing the pipe write end, which cause the 'Console.ReadLine()' continue to be blocked in the first child process. Fix: ---- Set the O_CLOEXEC flag when creating the redirection pipes. So that no child process would inherit the file descriptors referencing those pipes after the 'execve' call. /cc @stephentoub could you please review this PR? 19990 area-System.Net

Hi there, While looking into [ValueTuple.cs](https://github.com/dotnet/corefx/blob/master/src/System.ValueTuple/src/System/ValueTuple/ValueTuple.cs) class, I observed that there is one public method: ``` public bool Equals(ValueTuple other) { return true; } ``` This method always return ``true```.

Contributes to #7812 20014 area-System.Net UWP: System.Net.NetworkInformation 20015 area-Infrastructure Simple name conflict resolution is not working for NETStandard.Library.NETFramework "Originally reported here: https://github.com/dotnet/standard/issues/355 Conflict resolution does not try to resolve conflicts between simple name references because it does not attempt to duplicate assembly search path probing done by RAR. The SDK does removal of simple name references that overlap with nuget packages. This is ""good enough"" in most cases. The problem is that the NETStandard.Library.NETFramework package does not populate its references in a way that plugs into the SDK's logic. Instead we provide the references from targets. The reason for this is we need to hide these references from NuGet for the packages.config case: we don't want a packages.config project getting 100s of references added to its csproj. Taking the SDK out of the picture, we have the exact same simple-name conflict problem for packages.config. To fix this I propose the following: 1. We add a target to the NETStandard.Library.NETFramework project that removes simple name references that overlap with references added by our package, similar to https://github.com/dotnet/sdk/blob/1d81050cab00c6f9ab8bf5b984bc42eff2760c1e/src/Tasks/Microsoft.NET.Build.Tasks/build/Microsoft.PackageDependencyResolution.targets#L375. 2. In a packages.config project we make sure this runs before RAR. The only source of references is the users project file. 3. In a PackageReference project we make sure this runs after `ResolveLockFileReferences`. References may have come from user's project or nuget packages. 4. In a project.json project we make sure this runs after `ResolveNuGetPackageAssets`. References may have come from user's project or nuget packages. We can examine target sequencing to see if there is any way to accomplish 2-4 with a single target sequencing. /cc @weshaggard @dsplaisted @natemcmaster " 20017 area-System.Net Disable System.Net.Http tests on UAP/UAPAOT Disable a bunch of System.Net.Http tests on UAP/UAPAOT platform.

This is an issue on Onecore platforms where kernel32.dll is unavailable, so we should repackage the 4.0.1 AOT binaries that import from the api sets instead. This way, customers will be using the same dll for Debug as they are for Release when running under netcore50 for x86, x64, and arm. Packages produced after this change will have this structure: - runtime.win7-x64.*compression.4.3.0: - runtimes/win7-x64/native/clrcompression.dll - new build, non-appx, CFG enabled, kernel32 - runtimes/win7-x64/nativeassets/netcore50/clrcompression.dll - 4.0.1, appx, no CFG flag, API sets - runtime.win7-x86.*compression.4.3.0: - runtimes/win7-x86/native/clrcompression.dll - new build, non-appx, CFG enabled, kernel32 - runtimes/win7-x86/nativeassets/netcore50/clrcompression.dll - 4.0.1, appx, no CFG flag, API sets - runtime.win8-arm.*compression.4.3.0: - runtimes/win8-arm/native/clrcompression.dll - new build, non-appx, CFG enabled, kernel32 - runtimes/win8-arm/nativeassets/netcore50/clrcompression.dll - 4.0.1, appx, no CFG flag, API sets while the AOT packages are unchanged: - runtime.win10-x64-aot.*compression: - runtimes\win10-x64-aot\lib\netcore50\clrcompression.dll - 4.0.1, appx, no CFG flag, API sets - runtime.win10-x86-aot.*compression: - runtimes\win10-x86-aot\lib\netcore50\clrcompression.dll - 4.0.1, appx, no CFG flag, API sets - runtime.win10-arm-aot.*compression: - runtimes\win10-arm-aot\lib\netcore50\clrcompression.dll - 4.0.1, appx, no CFG flag, API sets cc: @MattWhilden @gkhanna79 @ericstj @weshaggard 20020 area-System.IO Behavior difference between CoreFX and desktop WRT IO and symlinks CoreFX handles symlink loops differently that desktop dotnet. On desktop, it throws UnauthorizedAccessException if you try to do any IO (such as File.Open) on such scenario. I'm not 100% CoreFX handle the windows case correctly, but I'm positive it doesn't in unix case as that scenario gets you an ELOOP and GetExceptionForIoErrno doesn't handle it. 20021 area-Infrastructure Move reference expansion to a target and handle simple name conflicts We cannot let simple name references that overlap with our assemblies reach RAR because RAR will choose the files in the targeting pack over the ones we add to the reference item, due to the default AssemblySearchPaths. We could change AssemblySearchPaths to consider all the NuGetPackage paths before `{TargetFrameworkDirectory}` but that has broader implications for compatibility and performance of RAR. I chose to follow a similar pattern to what the SDK does already and took the opportunity to move the reference item setting into the target as well, to more closely match what the SDK is doing.

The raw IntPtr handle is read from the certificate object, after which the certificate object isn't referenced anymore by the implementation; if the caller also no longer referenced the certificate, it's possible that it can be collected and its SafeHandle finalized before the copy ctor finishes reading state from the handle, leading to handle recycling and use-after-free errors. The second commit is then the result of me proactively searching the rest of the codebase for .Handle usage, and fixing any that (based just on examining the function itself and not on all possible call stacks) could potentially suffer a similar problem. cc: @ianhays, @bartonjs, @steveharter 20048 area-System.Net Fix HttpListenerFactory Dispose after failure If the ctor encounters a failure, _processPrefixListener may remain null; then when the factory is Dispose'd, it null refs.

I was able to narrow down the issue to the combination of Client on Windows and Kestrel behind Apache. I created a [repo](https://github.com/bruno-garcia/apache-mod-proxy-unrecognized-response) with a script to reproduce the issue. I'm unable to reproduce the issue when the client is running on Linux. Also, if I remove the break between requests, the issue doesn't not happen. If I change the interval from 5 seconds to 4 or 6 seconds, the issue doesn't happen either. That is in fact my current work around. 20067 area-System.Net Test for URI inconsistency Test behavior of #20046 case on each OS 20068 area-System.Net GetAsync_TrailingHeaders_Ignored failed with

Instead, `ForEach` method silently stops without throwing any exceptions and without executing all iterations. As a result, `Parallel.ForEach` may produce incomplete results. This behavior is observed for `Parallel.ForEach` method only, I was not able to reproduce it for `Parallel.For` method. Let's assume that we have a method that performs some work with the help of `Parallel.ForEach`: ```c# private static int DoWork(CancellationToken token) { var parallelOptions = new ParallelOptions { CancellationToken = token }; int counter = 0; Parallel.ForEach( new int[500], parallelOptions, dummy => { // Waste some time and keep CPU busy. for (long i = 0; i < 500; i++) ; Interlocked.Increment(ref counter); }); return counter; } ``` The method executes 500 tasks, each of them increments `counter` variable. Each task also does a small amount of work in the form of an empty `for` cycle so that it does not finish right away. If `DoWork` method finishes successfully, the returned value should be equal to the number of tasks executed (500). If `CancellationToken` is canceled while `Parallel.ForEach` is still running, then (per documentation) `Parallel.ForEach` should throw `OperationCanceledException`. The problem is that if some code launches `DoWork` method, waits for a short time (a few milliseconds), and then cancels `DoWork`, the value returned from `DoWork` may be smaller than 500: ```C# using (var tokenSource = new CancellationTokenSource()) { Task task = Task.Run(() => DoWork(tokenSource.Token)); // Waste some time and keep CPU busy before canceling DoWork. const long delay = 20000; for (long i = 0; i < delay; i++) ; tokenSource.Cancel(); try { int counter = await task; if (counter == 500) { // This branch should be executed if tokenSource.Cancel() was called too late // and Parallel.ForEach had already finished. } else { // This branch should never be executed, but execution goes there from time // to time. } } catch (OperationCanceledException) { // This is where we expect to land if DoWork was canceled. } } ``` The probability that `DoWork` will return a value different from 500 depends on the value of `delay` constant. On my workstation the issue appears if `delay` is between 10000 and 50000 (see the image below). X-axis is `delay` constant, Y-axis is the probability of `DoWork` returning a wrong value. ![failurerate](https://cloud.githubusercontent.com/assets/23439941/26311148/8c484ef2-3f03-11e7-9748-a30b1f19fd69.png) .NET Core console application that checks the probability of the issue: [ParallelTester.zip](https://github.com/dotnet/corefx/files/1018975/ParallelTester.zip) I was able to reproduce the issue for .NET Core only.

See https://github.com/dotnet/corefx/pull/19232 where I've temporarily checked in an appconfig file to address it for that test exe. We currently hardcode a list of config files we generate here https://github.com/dotnet/buildtools/blob/master/src/Microsoft.DotNet.Build.Tasks/PackageFiles/tests.targets#L130. Instead of hardcoding we should make that list extensible or automatically detect exe's and generate config files for them. While app.config is for the desktop runs we have a similar problem with the netcoreapp runs with runtimeconfig.json files that are needed. We should follow a similar process and generate them as well instead of having them be checked in along side all the test exe's. 20110 area-Infrastructure Need to generate a RunTest.cmd unique to the BuildConfiguration instead of Configuration Today if we have a configuration of netstandard in a test project and you try to run it once with one target group (say netcoreapp) and then a second time as another target group (say netfx) we keep overwriting the RunTest.cmd each time. We should ensure that the test output path takes into account the target you are running on as well as the target you are building for. I noticed this while helping with https://github.com/dotnet/corefx/pull/19232 and saw we were running the netfx tests from here `D:\git\corefx\bin\Windows_NT.AnyCPU.Debug\System.Runtime.Extensions.Tests\netstandard\RunTest.cmd` which didn't account for netfx as all. 20111 area-System.IO Associate #19965 with existing test There is a PR to fix the behavior in FileStream in CoreCLR.

We should eliminate most of this duplicated logic that we have here and in test.targets and instead generate a RunTest.Remote.cmd/sh (or something like that) that encapsulate the logic for running the remote application for the given platform. Then RemoteExecutorTestBase.cs can simply call run on that cmd or sh script that we generate and we don't have to keep maintaining the logic for figuring out how to run in multiple locations. cc @stephentoub @ViktorHofer @safern @danmosemsft This became pretty clear to me while helping with https://github.com/dotnet/corefx/pull/19232 and the UWP RemoteExecutor issues we are still having. 20115 area-System.Xml add missing stub constructors Add private constructors to the System.Xml.XmlSchemaSet.Tests, where the constructors were missing.

This tests are tracked by: https://github.com/dotnet/corefx/issues/19967 cc: @davidsh @CIPop @stephentoub 20147 area-System.Runtime System.Environment - Writing environment variables on Mac/Linux "Hi, @stephentoub @jkotas @JeremyKuhne @eerhardt I've been looking at System.Environment and how to read and write Environment variables on Linux/Mac, using the 1.04 release and 2.0 preview currently available. With the 2.0 preview, the APIs expanded to allowing the use of the EnvironmentVariableTarget enum, which features the Process, User and Machine scope where as prior to this, only the Process scope was implemented as a default. Unfortunately, this is not helpful at all on Linux/Mac. With the current API in 2.0 preview (and prior API versions), setting environment variables on Linux/Mac do not bind to the underlying shell process, they live within the scope of the dotnet process executing the assembly setting the environment variable(s) and stop to exist once dotnet terminates assembly execution. Using other scopes (e.g. User, Machine) on non-Windows platforms) is not mapped in the implementation. This is fairly useless for persisting information to be used by other processes. Example: ```csharp using System; using System.Runtime.InteropServices; class Sample { protected static string myVarPrefix = ""FOOBAR_""; protected static string myVarA = myVarPrefix + ""DEFAULT""; // default process protected static string myVarB = myVarPrefix + ""CURRENT""; // Current Process protected static string myVarC = myVarPrefix + ""USER""; // Current User protected static string myVarD = myVarPrefix + ""MACHINE""; // Local Machine protected static string myVarValue = ""FOOBAR""; public static void Main() { Console.WriteLine(""Setting default process...""); Environment.SetEnvironmentVariable(myVarA, myVarValue); Console.WriteLine(""Setting current process...""); Environment.SetEnvironmentVariable(myVarB, myVarValue, EnvironmentVariableTarget.Process); Console.WriteLine(""Setting user...""); Environment.SetEnvironmentVariable(myVarC, myVarValue, EnvironmentVariableTarget.User); Console.WriteLine(""Setting machine...""); try { Environment.SetEnvironmentVariable(myVarD, myVarValue, EnvironmentVariableTarget.Machine); } catch (System.Exception) { Console.WriteLine(""Failed setting machine...""); } if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux)) System.Diagnostics.Process.Start(""/bin/bash"", ""-c export""); Console.Write(""Press to exit... ""); while (Console.ReadKey(true).Key != ConsoleKey.Enter) {} } } ``` Only FOOBAR_DEFAULT and FOOBAR_CURRENT will be set on Linux while the app executes and running `/bin/bash -c export` _after_ this sample terminated shows that both variables are gone and don't exist anymore. What's the plan here to fix this? To my knowledge, Mono simply implements reading/writing environment variables on Unix/Linux using the same namespace(s) as in .NET, Mono.Unix.Native/Mono.Posix have nothing added to specifically read and write environment variables. Hence, my expectation would be to have this very basic stuff handled with an identical abstraction in CoreFX that is not platform dependent? For Linux, there is of course no scope such as ""Machine"" and ""User"" would bind to the underlying shell process (and any child process starting after the fact through inheritance). **The current scope of implementation in 2.0 preview should be fixed to make the ""User"" scope work on Mac/Linux, where it binds to the scope of the underlying shell.** As a **workaround** to properly set environment variables on Linux/Mac, one could simply query `RuntimeInformation.IsOSPlatform(OSPlatform.Linux)` and use System.IO to check for the presence of any familiar shell (sh, ksh, and bash, maybe also from other shell families such as csh) in the file system and then write simple wrappers calling to their built-in functions to set environment variables correctly such as ```csharp // omitting check for presence of bash binary if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux)) System.Diagnostics.Process.Start(""/bin/bash"", ""-c export "" + variable + ""="" + value); ``` Whatever the API implementation in CoreFX is going to be (for Mac/Linux), it should work and have the same outcome as making a call to the shell built-ins for managing environment variables. -- Thanks, Tobias W.

From what I look, most of them are because we now don't bring to the closure the roslyn libraries anymore, plus we have made some types from public->internal but they weren't exposed through contracts so I guess we should be fine. Last remaining pieces for this validation work to be done, is to add those installer/zip Apicompat checks, and adding official runs so that we have this working on some cadence.

This sounds like a bug. It should be possible for the server to close the connection and still have the client receive all of the data sent before that, assuming the server is doing a proper shutdown of the connection. " 20157 area-System.Runtime Adds runtime feature detection support for default interface method This proposal introduces a new flag for the presence of default interface methods (see the references below). ```csharp public static class RuntimeFeature { /// /// Indicates that this version of runtime supports default interface method implementations. /// // Original name, adjusted by API review: InterfaceDefaultMethods public const string DefaultImplementationsOfInterfaces = nameof(DefaultImplementationsOfInterfaces); /// /// Checks whether a certain feature is supported by the Runtime. /// public static bool IsSupported(string feature) { if (feature == DefaultImplementationsOfInterfaces ) return true; return false; } } ``` `System.Runtime.CompilerServices.RuntimeFeature.IsSupported` returning true indicates that the runtime supports interface default method feature. It only indicates the presence of the feature and does *NOT* necessarily translate to any specific runtime behavior. This means that future runtime will keep returning true for this feature even in the case of breaking behavior changes (perhaps the only exception is when we decide to take the feature out, but that probably would never happen once we ship). Practically speaking, returning true means that the runtime supports the set of behaviors that is defined by first version of interface default method feature in the runtime (that we ship), plus/minus any future behavior changes that may or may not be breaking. If there are any requirements to support detection of any future behavior changes (that clients such as compilers care about), we can introduce a new flag that corresponds to the new behavior. Returning true would indicate the new behavior while returning false indicates otherwise. # References [C# Language Spec Link](https://github.com/dotnet/csharplang/blob/master/proposals/default-interface-methods.md) [Runtime Feature Support API proposal](https://github.com/dotnet/corefx/issues/17116) [CoreCLR issue] (https://github.com/dotnet/coreclr/issues/10504) Runtime Design Spec (TBD) 20158 area-Infrastructure Build.cmd should pick up and use the VS 2017 developer command prompt automatically I only have VS2017 installed on my PC, but when I run `build.cmd` from the normal command prompt (`cmd.exe`) I get > Error: Visual Studio 2015 or 2017 required. > Please see https://github.com/dotnet/corefx/blob/master/Documentation/project-docs/developer-guide.md for build instructions.

If I remove this call - my simple SqlClient tests (open a connection, execute some query, etc..) will pass without the **sni.dll**. So the question is - what **sni.dll** is used for on Windows+ManagedSNI and can we just wrap it like this. ```csharp internal static uint SNIInitialize() { return SNIInitialize(IntPtr.Zero); } ``` TO: ```csharp internal static uint SNIInitialize() { try { return SNIInitialize(IntPtr.Zero); } catch (DllNotFoundException) { return TdsEnums.SNI_UNINITIALIZED; } } ```" 20180 area-System.Net [documentation] WebHeaderCollection.Add(new string('a', 65536)) does not throw as documented "From https://msdn.microsoft.com/en-us/library/y280s7kx(v=vs.110).aspx > ArgumentOutOfRangeException | The length of value is greater than 65535.

It looks like the query string `?name1=+&name2=\u1234&\u0100=value&name3=\u00FF` is encoded differently in netfx and netcoreapp. I couldn't quite figure this out so I left it out of this PR. It looks like the listener is actually receiving different content from the connected socket as the value of `_cookedUrlQuery/m_CookedUrlQuery` in HttpListenerRequest is different between netfx and netcoreapp. 20184 area-System.Net Fix ContentLength64, SendChunk, and KeepAlive in managed HttpListener Fixes https://github.com/dotnet/corefx/issues/19973 Fixes https://github.com/dotnet/corefx/issues/19978 For the most part, this just moves functionality from the Windows implementation to be shared, deleting the managed counterpart. In some cases, in particular around the handling of content length, this resulted in more changes through the HttpListenerResponse managed implementation, as various places check for content length vs chunked behaviors. The Windows implementation has not changed (other than some of its functions moving to be in the shared file). As part of this, I fixed a few other differences I noted even though they weren't causing tests to fail, e.g. doing an asynchronous write in Close when willBlock is false. cc: @janvorli, @hughbe, @Priya91, @geoffkizer 20185 area-Microsoft.CSharp Fix newly added Microsoft.CSharp tests on ILC 20186 area-System.Threading change Sleep test to use InRange to see value relates to https://github.com/dotnet/corefx/issues/20173 20187 area-Infrastructure Add win-arm and win-arm64 to RID graph.

These types are frequently used to represent both handles/pointers and integers whose size depend on the underlying platform. When being used to represent the latter (platform sized integer) type, users may find a difficult time performing some basic operations, such as comparing two `native ints` to determine sort order. Additionally, with the proposed C# `Native Sized Number Types` (https://github.com/dotnet/csharplang/issues/435) where language support for the primitive operations will be exposed (currently this will be done via partial erasure), the use of `System.IntPtr` and `System.UIntPtr` as `native int` types will become more prevalent (F# is one language that already exposes these operators). As such, these types should be modified to expose a set of APIs that make other common operations easier to perform. ### Proposed API The proposed API here only shows the members that would be new to the types. **System.IntPtr** ```C# [StructLayout(LayoutKind.Sequential)] // This is implicitly set by the compiler, but should be explicitly declared, as it is done for System.Int32 public struct IntPtr : IComparable, IComparable, IComparable, IEquatable, IFormattable { public static IntPtr MaxValue { get; } public static IntPtr MinValue { get; } public static bool operator ==(IntPtr left, int right); public static bool operator !=(IntPtr left, int right); int IComparable.CompareTo(object value); // Explicitly implemented to ensure that users still get compile-time type checking public int CompareTo(int value); // ECMA-335 defines binary comparisons for IntPtr/int and IntPtr/IntPtr public int CompareTo(IntPtr value); public bool Equals(int other); // ECMA-335 defines binary comparisons for IntPtr/int and IntPtr/IntPtr public bool Equals(IntPtr other); // This is currently explicitly implemented as IEquatable.Equals(IntPtr other) public string ToString(IFormatProvider provider); public string ToString(string format, IFormatProvider provider); public static IntPtr Parse(string s); public static IntPtr Parse(string s, NumberStyles style); public static IntPtr Parse(string s, IFormatProvider provider); public static IntPtr Parse(string s, NumberStyles style, IFormatProvider provider); public static bool TryParse(string s, out IntPtr result); public static bool TryParse(string s, NumberStyles style, IFormatProvider provider, out IntPtr result); } ``` **System.UIntPtr** ```C# public struct UIntPtr : IComparable, IComparable, IComparable, IEquatable, IFormattable { public static UIntPtr MaxValue { get; } public static UIntPtr MinValue { get; } public static bool operator ==(UIntPtr left, uint right); public static bool operator !=(UIntPtr left, uint right); int IComparable.CompareTo(object value); // Explicitly implemented to ensure that users still get compile-time type checking public int CompareTo(uint value); // ECMA-335 defines binary comparisons for IntPtr/int and IntPtr/IntPtr public int CompareTo(UIntPtr value); public bool Equals(uint other); // ECMA-335 defines binary comparisons for IntPtr/int and IntPtr/IntPtr public bool Equals(UIntPtr other); // This is currently explicitly implemented as IEquatable.Equals(UIntPtr other) public string ToString(string format); // This is currently exposed on System.IntPtr, but not on System.UIntPtr public string ToString(IFormatProvider provider); public string ToString(string format, IFormatProvider provider); public static UIntPtr Parse(string s); public static UIntPtr Parse(string s, NumberStyles style); public static UIntPtr Parse(string s, IFormatProvider provider); public static UIntPtr Parse(string s, NumberStyles style, IFormatProvider provider); public static bool TryParse(string s, out UIntPtr result); public static bool TryParse(string s, NumberStyles style, IFormatProvider provider, out UIntPtr result); } ``` ### Other Thoughts Implementing `System.IConvertible` is done by the other primitive types and may be useful in some cases here as well. It might be worthwhile having `int` implement `IComparable` and `IEquatable`, given that these are valid operations as well. 20258 area-Infrastructure "Move ""GenerateReferenceSource"" target into buildtools" "We should move this new target into buildtools if we decide that the functionality is general-purpose enough to warrant it.

For Windows this change simply sets the CREATE_NEW_PROCESS_GROUP flag when creating the process.

To achieve the latter, UWP toolchain uses one `XmlReflectionImporter` to import *all types* (all types require serialization in the app) so that the `extraTypes` would be treated as known types. But there're some problems with this. 1. The type would have more known types than those included by `extraTypes`. 2. There might be type conflicts as the importer imports all types and the type scope grows. And etc. The fix is to make the constructor to always use reflection based serialization.

This likely means removing the source code from mono and importing code from the submodule link that already exists. **In progress. Mono has begun using some portions of the Windows implementation already.** * [x] Port mono's tests for System.Drawing, making any modifications necessary to ensure that they pass on the Windows implementation, which is our baseline for compatibility. **In progress** * [ ] Consolidate differences between the Windows and Unix versions of the library. Document all differences in behavior and mark test cases appropriately. -------------------------------- System.Drawing has been identified as one of the top most-used assemblies that are missing from .NET Core. Although there are 3rd-party alternatives that provide more modern versions of the same functionality ([ImageSharp](https://github.com/JimBobSquarePants/ImageSharp), [SkiaSharp](https://github.com/mono/SkiaSharp), etc.), we believe there is still value in providing a binary-compatible implementation of System.Drawing itself. This issue is intended to document and track the work items involved. There are still lots of open questions; feedback and suggestions are encouraged. ## Priorities: * Simplify migration from .NET Framework to .NET Core. We need to be binary compatible (no recompilation needed for existing assets), and we need to match the behavior as closely as possible. * Support System.Drawing where mono does, and facilitate code sharing between our implementations. As part of this, we will be open-sourcing the original Windows implementation from .NET Framework. This should allow us to improve mono's implementation where it diverges, and hopefully reduce the maintenance burden between us by consolidating code and effort. * **NON-GOALS**: We do not view this library as an opportunity for innovation, nor will we invest significant amounts of effort into optimizing or refactoring it. High performance, rich OS-specific functionality, and a redesigned, modern API are not areas we are interested in investing in as part of this effort. There are alternative libraries which target all of those issues and more. # Plan System.Drawing is, fundamentally, a very thin wrapper over the GDI+ component on Windows. Worse yet, it is not available for UWP applications, so support is limited strictly to Win32 applications. This makes cross-platform implementations difficult, and the largest chunk of work involved with this effort will be figuring out how we can support the library on all of our platforms, and maintaining compatibility between them. There are several existing implementations that we can leverage, but none will support all of our platforms by themselves. We may need several distinct backends in order to get full cross-platform support, although some options could avoid that. The below chart maps implementation approaches (rows) with platform applicability (columns): |Win32 | UWP | macOS | Linux / Others -----|--------|-------|---------|--------- .NET Framework Version (GDI+) | ✓ | X | X | X Direct2D/Win2D|✓|✓|X|X Mono/libgdiplus|✓|X|✓|✓ Xamarin/CoreGraphics|X|X|✓|X Managed|✓|✓|✓|✓ ### .NET Framework Version (GDI+) This is the existing implementation from the .NET Framework on Windows. It is a very thin wrapper around GDI+. * :heavy_check_mark: Baseline implementation. Well-tested, stable. * :x: Can only be used in non-UWP Windows apps (Win32). ### Direct2D/Win2D In order to get UWP support, we could implement a compatibility layer over Direct2D, or Win2D. * :heavy_check_mark: GPU acceleration * :x: Only buys us UWP support over the existing .NET Framework implementation. * :x: High implementation cost * Can be shared between Win32 and UWP applications (Windows 8+ only). ### Mono/libgdiplus This is the implementation used in mono. It uses a complicated native shim called ""libgdiplus"", which relies on a large set of native binaries. * :heavy_check_mark: libgdiplus is available in a large number of package managers across the Unix ecosystem already. This means we can treat the dependency the same way we do the other native dependencies for .NET Core. * :x: Native code adds a lot of complexity for new devs. ### Xamarin/CoreGraphics This is a specialized implementation used by Xamarin, in support of macOS and iOS. Unlike the ""libgdiplus"" mono version, it only uses CoreGraphics (a system component). * :heavy_check_mark: No extra native dependencies; only uses system libraries. * :x: macOS-specific. Could be used for iOS (not supported by .NET Core yet). ### Managed (ImageSharp or custom) One option is to implement the library in managed code. We can call into an existing library, like ImageSharp, for image-processing and graphics functionality. This is very desirable for a lot of reasons, but it does have a higher implementation cost. * :heavy_check_mark: Can be used everywhere. * :heavy_check_mark: Can achieve uniform behavior everywhere (at the expense of conformity with .NET Framework). * :heavy_check_mark: Lower maintenance costs in the long-term. * :x: High implementation cost. ## Windows-Specific One option is to treat the library as a Windows-specific component, similar to Registry. Attempting to install and load the library on other platforms would throw PlatformNotSupportedException's, as Registry does. ## Tests We do not have a very good existing test suite in the .NET Framework. The library is mainly covered indirectly, through other components like WinForms. Mono has a good set of conformance tests for their implementation, which we should be able to re-use. Where appropriate, we should also consider test cases which directly compare output from the .NET Framework implementation and other implementations (assuming we choose to support such things). ## Location An open question is where this library should live. If we take third-party dependencies to support some platforms, we may not want this code to live in corefx. ## Printing Functionality One thing skimmed over above is the fact that System.Drawing exposes a lot of functionality for printing images and documents. This poses a different problem from image-processing and graphics, which can be implemented portably. We may decide to exclude all printing-related portions of the library. ## Future investments Once the library is supported on all platforms, we will accept small, targeted improvements to the library, keeping in mind that legacy compatibility is the only important metric for the library. We will not want to merge any code that refactors, optimizes, or augments the Windows version until we have a fully-working cross-platform implementation. This matches our strategy with other compatibility libraries, like System.IO.SerialPort. @marek-safar @jimbobsquarepants @ViktorHofer @qmfrederik @karelz " 20326 area-Infrastructure How to develop in corefx for UWP Opening on behalf of @CIPop from https://github.com/dotnet/corefx/pull/20322#issuecomment-304102737 >@ericstj @weshaggard /cc @karelz @DavidGoll Could you please help with the following: >1.

The lack of Performance Counters in .NET Core is blocking me to use ASP.NET Core for Enterprise applications. I found many issues telling us to use EventCounters, but I couldn't find docs or even code in the repository using it. There is any docs? Anyway, ETW events doesn't replace Performance Counters, I use it to monitor Req/sec and I can't see how to do it easily with ETW, or ask the support team to monitor or collect it.

I started to try to add a test to the System.Diagnostics.DiagnosticSource project, but it is not easy because there is no easy way to turn on the EventSource from outside the process (you need to be set up to turn it on using ETW). This gets ugly because ETW is windows-specific. It occurs to me that the EventSource testing ALREADY set up to do this (use ETW to control the logging from outside the process). Thus my proposal is to add some Microsoft-Diagnostics-DiagnosticSource testing (most specifically having this source turned on before process start) added to the EventSource testing. There was an issue with this (as EventSource is part of CoreCLR not CoreFX), so I would like Brian to weigh in before proceeding. @brianrob @lmolkova 20335 area-Infrastructure Update CoreClr to preview2-25326-01 (release/2.0.0) 20336 area-System.Diagnostics Fix link in docs User reported to me that a link did not work.

" 20339 area-System.Data Added cleanup for cached async state in SqlCommand's EndExecute metho… …ds before they throw exceptions. Without this cleanup, a subsequent command execution will fail since it will appear as though other async commands are still pending. When running SqlClient's TVP tests with Managed SNI enabled, exceptions were getting thrown earlier during async execution than with Native SNI, which surfaced this bug. The SqlCommand would throw an exception without resetting the async state, causing subsequent commands to fail due to pending async operations. This async state cleanup matches the other exception cleanup behavior elsewhere in SqlCommand. Fixes in master #20340 20340 area-System.Data Command execution fails in SqlClient TvpTest due to pending async operations after cancellation When running the SqlClient TVPTests with Managed SNI enabled, command execution fails due to pending async operations in SqlCommand after cancelling a previous command.

Notable omission is the `ModuleDefinition` record. ### Proposed API ```csharp namespace System.Reflection.Metadata { public struct ModuleDefinition { public CustomAttributeHandleCollection GetCustomAttributes(); } } ``` ### Other thoughts This can be worked around with `MetadataReader.GetCustomAttributes(System.Reflection.Metadata.Ecma335.MetadataTokens.EntityHandle(0x1))`, but it's rather awkward. 20346 area-System.Net fix HttpListener chunked encoding handling Partial fix for #20246 (1) CompletedSynchronously logic in HttpStreamAsyncResult is bogus.

We need to test nread == 0 on the result of the underlying read, not on the result after processing the chunk data -- for which nread == 0 is perfectly valid. (3) There's some weird logic in ChunkStream around handling offset/size that smells bad but doesn't actually seem to matter in practice as used; add a comment and assert and a test, and remove some related dead code (4) Re-enable some tests @stephentoub @danmosemsft 20347 area-System.Runtime "Test: System.Tests.EnvironmentTests/CurrentDirectory_SetToValidOtherDirectory failed with ""Xunit.Sdk.EqualException""" Opened on behalf of @Jiayili1 The test `System.Tests.EnvironmentTests/CurrentDirectory_SetToValidOtherDirectory` has failed.

It allows substring operations on string to not allocate but return segments using offset and length. It's the spiritual equivalent of `ArraySegment` for string. Note that `Span` will also allow slicing, but spans have different type system constraints that not all consumers can -- or want to -- opt into. ### Proposed API Shape Starting point is the existing API shape from ASP.NET. We should, however, diff it against the latest surface of `string`. ```C# namespace System.Text { public struct StringSegment : IEquatable, IEquatable { public static readonly StringSegment Empty; public StringSegment(string buffer); public StringSegment(string buffer, int offset, int length); public string Buffer { get; } public int Offset { get; } public int Length { get; } public string Value { get; } public bool HasValue { get; } public char this[int index] { get; } public override bool Equals(object obj); public bool Equals(StringSegment other); public bool Equals(StringSegment other, StringComparison comparisonType); public static bool Equals(StringSegment a, StringSegment b, StringComparison comparisonType); public bool Equals(string text); public bool Equals(string text, StringComparison comparisonType); public override int GetHashCode(); public static bool operator ==(StringSegment left, StringSegment right); public static bool operator !=(StringSegment left, StringSegment right); public static implicit operator StringSegment(string value); public bool StartsWith(string text, StringComparison comparisonType); public bool EndsWith(string text, StringComparison comparisonType); public string Substring(int offset); public string Substring(int offset, int length); public StringSegment Subsegment(int offset); public StringSegment Subsegment(int offset, int length); public int IndexOf(char c, int start, int count); public int IndexOf(char c, int start); public int IndexOf(char c); public int IndexOfAny(char[] anyOf, int startIndex, int count); public int IndexOfAny(char[] anyOf, int startIndex); public int IndexOfAny(char[] anyOf); public int LastIndexOf(char value); public StringSegment Trim(); public StringSegment TrimStart(); public StringSegment TrimEnd(); public StringTokenizer Split(char[] chars); public static bool IsNullOrEmpty(StringSegment value); public override string ToString(); } } ``` ### Other APIs In order to make the API useful, we could also define methods on `String` that allow returning segments, e.g. ```C# namespace String { public partial class String { public StringSegment SubSegment(int startIndex) // or Subsegment public StringSegment SubSegment(int startIndex, int length) } } ``` 20381 area-System.Net 2.0 Port: AppCompat: converting two HWR properties to no-op.

System.Runtime.Extensions.Tests.dll -method System.Tests.Environment_Exit.ExitCode_VoidMainAppReturnsSetValue fails on ILC because it needs to launch a child process using a test assembly and the build pipeline won't run ILC on that test assembly or copy it to the output directory. This test cannot use RemoteExecutor because it's testing ExitCode and needs to know that it is the true main method. If we want to test this scenario for ILC, it should best be done in a standalone test (probably living in CoreRT) that doesn't sit on top of all this xunit stuff. It's not that we can't hack the build pipeline again to accommodate this, it's more that people (like me) investigating test failures on ILC will not appreciate having yet another 3-5 minutes added to the build time of this project because of one single test. 20388 area-System.Diagnostics Desktop: System.Diagnostics.Tests.ProcessStartInfoTests.StartInfo_TextFile_ShellExecute fails occasionally on NETFX Failed test: System.Diagnostics.Tests.ProcessStartInfoTests.StartInfo_TextFile_ShellExecute (from System.Diagnostics.Process.Tests) Detail: https://ci.dot.net/job/dotnet_corefx/job/master/job/outerloop_netfx_windows_nt_debug/67/testReport/System.Diagnostics.Tests/ProcessStartInfoTests/StartInfo_TextFile_ShellExecute/ Configuration: outerloop_netfx_windows_nt_debug MESSAGE: ~~~ System.NullReferenceException : Object reference not set to an instance of an object. ~~~ STACK TRACE: ~~~ at System.Diagnostics.Tests.ProcessStartInfoTests.StartInfo_TextFile_ShellExecute() in D:\j\workspace\outerloop_net---903ddde6\src\System.Diagnostics.Process\tests\ProcessStartInfoTests.cs:line 1013 ~~~ 20389 area-System.Net [Porting][HttpListener] HttpListenerContext.AcceptWebSocketContextAsync throws PNSE for authentication "The following test passes on desktop, but fails with netcoreapp: ```c# [ConditionalFact(nameof(IsNotWindows7OrUapCore))] [ActiveIssue(123, TargetFrameworkMonikers.Netcoreapp)] public async Task AcceptWebSocketAsync_AuthorizationInHeaders_ThrowsNotImplementedException() { Socket.Options.SetRequestHeader(""Authorization"", ""Basic "" + Convert.ToBase64String(Encoding.ASCII.GetBytes(""user:password""))); Factory.GetListener().AuthenticationSchemes = AuthenticationSchemes.Basic; HttpListenerContext context = await GetWebSocketContext(); Assert.Equal(""user"", context.User.Identity.Name); HttpListenerWebSocketContext webSocketContext = await context.AcceptWebSocketAsync(null); IPrincipal user = webSocketContext.User; // Should be copied as User gets disposed when HttpListenerContext is closed.

"`ClaimsIdentity` currently expose the `Name` property but feels like it missing the `NameIdentifier` property. Since `Claim` is the recommended way to work with authentication and the most common property that developers needs to work with when dealing with users is the UserId, known as the `subject` or `NameIdentifier` claim, it's a great opportunity to make a better api for developers to access that value. # Rationale and Usage This is certainly a nice-to-have, but it is a long-standing issue in various versions of ASP.NET Identity where there were always questions and *workarounds* in how to get the user id (a pretty basic need), the use of different `Type` for the primary key made methods (extension or not) hard to deal with from usage and for library to implement them. Having the `NameIdentifier` claim as a property (which is already on the `ClaimsIdentity` object) would make developers access the userId value without the need of a dependency (like `UserManager`) in a consistent and reliable way. Note: This is **not** about `Identity` specific, I'm using it as an example. Historically the `Name` property on `ClaimsIdentity` were used many times to have the User Identifier since the id is normally more helpful than the Name, unfortunately one must pick one or the other while both are useful and serve different purposes and also feels like a hack to have a property that doesn't really represent it's intent. ## Examples (without this change) For example, using Identity, to get the the NameIdentifier Claim right you have 2 options with it's respective problems: 1 - Get the claim as it were any other claim `string userId = User.FindFirstValue(ClaimTypes.NameIdentifier);` configuring another claim for the Identifier (like ""sub"" in the case of OIDC) will break existing code and needs to be updated to `User.FindFirstValue(""claimType"");` 2 - Using the UserManager (similar for any other developer/library custom implementation) `string userId = Microsoft.AspNetCore.Identity.UserManager().GetUserId(User);` This won't break if the claimtype changes but requires to have a dependency on the `UserManager` (or any custom implementation) everywhere you would need to get the userid which shouldn't be needed at all. ## Example (with this change) `User.Identity.NameIdentifier` # Proposed API ```c# public ClaimsIdentity(IIdentity identity, IEnumerable claims, string authenticationType, string nameType, string roleType, string nameIdentifierType) public const string DefaultNameIdentifierClaimType = ClaimTypes.NameIdentifier; public string NameIdentifierClaimType { get; } public virtual string NameIdentifier { get; } ``` # Detail Adding the `NameIdentifier` and `NameIdentifierClaimType` property to `ClaimsIdentity` solve both problems, you can change the `ClaimIdentifierType` like this: ```c# services.Configure(options => { options.ClaimsIdentity.UserIdClaimType = OpenIdConnectConstants.Claims.Subject; }); ``` and code using `ClaimIdentity.NameIdentifier` will return the *right* thing. No dependency, library, or custom code needed. # Open Questions Should `NameIdentifier` be the right name for this property? I'm not aware where the name came from nor the history behind this, while NameIdentifier sounds good may there's opportunity to make it even better.

In my case, I'm trying to read an ECDSA public/private key pair out of a PKCS8 container. In .NET Framework and .NET Core on Windows, this is possible with the following: ``` static ECDsa CreateKeyFromDataCng(byte[] data) => new ECDsaCng(CngKey.Import(data, CngKeyBlobFormat.Pkcs8PrivateBlob)); ``` Under macOS (and I assume Linux too), this throws a `PlatformNotSupportedException`. As per #18733, .NET Core can handle loading ECDSA keys from an X509 structure. Would it be possible to implement the Cng suite of APIs with a backing from a non-Windows-CNG source such as OpenSSL on Linux or the Apple crypto libraries on macOS? Failing that, are there any plans for a unified cryptography API in .NET Standard future which would enable a single API call to work across all platforms for fiddly cryptography bits such as this?

Since the HttpListener API doesn't support binding to 0 and having the OS pick an available port, the tests iterate through ports looking for one the HttpListener can bind to. Often the listener ends up on the same port as the previous test, which means the client is effectively given the same Uri on one test as it was on its previous test. The Windows ClientWebSocket is using connection pooling, and while this analysis may not be correct, it appears that sometimes there is a race condition whereby the client tries to reuse an existing connection for test N+1 after the server has closed that connection for test N. This then results in the client failing the connection, with an error like: ``` System.Net.WebSockets.WebSocketException : Unable to connect to the remote server ---- System.Net.WebSockets.WebSocketException : Unable to connect to the remote server -------- System.Net.Http.WinHttpException : The connection with the server was terminated abnormally Stack Trace: C:\Users\stoub\Source\Repos\corefx\src\System.Net.WebSockets.Client\src\System\Net\WebSockets\WebSocketHandle.Win32.cs(60,0): at System.Net.WebSockets.WebSocketHandle.d__20.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) C:\Users\stoub\Source\Repos\corefx\src\System.Net.WebSockets.Client\src\System\Net\WebSockets\ClientWebSocket.cs(157,0): at System.Net.WebSockets.ClientWebSocket.d__16.MoveNext() ``` Disabling the per-process connection pooling in ClientWebSocket, e.g. ```C# uint optionData = 1; if (!Interop.WinHttp.WinHttpSetOption( _operation.SessionHandle, Interop.WinHttp.WINHTTP_OPTION_MAX_CONNS_PER_SERVER, ref optionData)) { WinHttpException.ThrowExceptionUsingLastError(); } ``` causes the failure to go away, as does changing the tests to try to use a different port than was used by the last test. 20440 area-System.Net Workaround pooling issue with managed HttpListener and Windows ClientWebSocket When using the managed HttpListener on Windows, try to create each HttpListener on a different port than the one used for the last test's HttpListener.

With this change, now we will restore the right one so the tests can run and pass. 20456 area-System.IO FileSystemInfo.Attributes set to -1 if the file gets deleted while in an enumeration on Unix "Summary ---------- When a file gets deleted (or renamed) during an enumeration of all files in the parent directory, accessing the `'Attributes'` property of the FileInfo object returns value `'-1'`. This seems very bad to me because it's not a meaningful `FileAttributes` value and thus the subsequent tests like `(filesystemInfo.Attributes & FileAttributes.Hidden) != 0` will give unexpected results and cause problems. There are 2 issues in my observation: 1. Inconsistent behavior between Windows and Unix platforms. - On Windows, `filesystemInfo.Attributes` returns the original attributes even though the file gets deleted during the enumeration. 2. Breaking change in behavior from `Microsoft.NetCore.App 2.0.0-preview1-002106-00` to `Microsoft.NetCore.App 2.0.0-preview2-25324-03` - With version `2.0.0-preview1-002106-00`, `filesystemInfo.Attributes` raises an `FileNotFoundException` exception. - With version `2.0.0-preview2-25324-03`, `filesystemInfo.Attributes` returns -1 Thought --------- I think it would be the best if we can have the consistent behavior between Windows and Unix platforms. If that's technically not possible, then throwing `FileNotFoundException` exception is better than returnning `-1` because `-1` is not a meaningful value for `FileAttributes` and it will mislead the subsequent code.

On Windows 10 the problem is not observed. I attach the output of the program above. All requests that running for more than 4 seconds load 1 core of the processor by 100%. If you run several parallel tasks, the entire processor will be loaded 100%. Also, the cancellation takes place much later than 4 seconds. The problem is observed for different proxy servers and is not always repeated for any particular proxy server.

The `ProcessStartInfo` class provides `StandardOutputEncoding` and `StandardErrorEncoding` properties to allow callers to override the encoding for those. This simply changes the encoding passed to the `StreamReader` object which wraps the underlying process byte stream. To more naturally support talking to a process that uses a different encoding than the current process's console encoding, we should add a new property to `ProcessStartInfo`: ``` public Encoding StandardInputEncoding { get; set; } ``` This would have the same semantics as the existing properties: * Defaults to `null`, which means use the default encoding * If specified and the input stream is not redirected, an exception is thrown on process start [EDIT] Added latest proposal link by @karelz 20500 area-System.Net Fix HttpClient on Unix handling of 0-len content with chunked upload When there's a disagreement between Content-Length and Transfer-Encoding being specified in the HttpRequestMessage, WinHttpHandler sanitizes the request to ensure it makes sense. CurlHandler does the same thing, except it's currently doing it a bit too late in the send process: it should be doing it before the curl easy handle is configured based on the contents of the request, but it's currently doing it in the middle, after some configuration has already been done based on the content length. The fix is simply to move the sanitization up earlier. For the most part this didn't matter, but it was manifesting as incorrect handling of 0-length content with chunked uploads, where neither the content length nor chunks were being sent. cc: @geoffkizer, @davidsh Fixes https://github.com/dotnet/corefx/issues/20419 20501 area-Serialization Disable lazy serialization tests on netcoreapp Fixes https://github.com/dotnet/corefx/pull/20499 20502 area-System.Collections [BlockingCollection] Add TimeSpan parameter to TryAdd and TryTake (and a few questions) Hi! I would like to start contributing to open source projects and since I love C# and the .NET environment, this looks like a great place to start. However, I'm quite new to all this and so, I have a few questions on how to proceed. First of all, what I want to do is relatively simple. I want to add the following methods to the BlockingCollection classe: ```c# public bool TryAdd(out T item, TimeSpan timeout, CancellationToken cancellationToken); public bool TryTake(out T item, TimeSpan timeout, CancellationToken cancellationToken); ``` The original reason for this is that I usually prefer using a TimeSpan object wherever possible since it makes the intention clear and recently had to use BlockingCollection for a project and noticed that some of the Try* methods don't have a overload that takes a TimeSpan parameter. Since this is an easy addition (unless I'm missing something) I though it would be a nice way to start contributing. Besides, it adds consistency. Also, I know this could be implemented as an extension method but that defeats the purpose of contributing :) Regarding my questions. - I need to open a issue for every pull request? If so, can I use this one or should I open new one? - Since this is an API change, do I need to do something special besides opening the issue and if approved, submit the PR? - What are the naming conventions for testing method names? BlockingCollectionTest have some of the following: - TestConcurrentAddAnyTakeAny - TestAddAnyTakeAny_Longrunning - Test17_AddExceptions Is there anything else I'm missing?

This means that if more than 5 minutes pass from usages of a certificate private key (where the cert was opened from a PFX) the user gets prompted for a password for the temporary keychain. Since that keychain has a randomly generated password it's not really possible for the user to accomplish this successfully. No tests cover this scenario, since they require more than 5 minutes of idle time.

This makes migration towards async methods and/or mocking the async methods for testing difficult. I am proposing we introduce an intermediary interface `IDbConnectionAsync` that is derived from `IDbConnection` and will be implemented by `DbConnection`. Similarly, introduce `IDbCommandAsync` between `IDbCommand` and `DbCommand`. These interfaces will contain `public async` methods that is missing from the original interfaces. ## Rationale and Usage Consider the following snippet illustrating an `IDbCommand` factory. There are two factory methods, one for regular and one for the async variant. I've included unit test methods to verify the factory calls `CreateCommand()` and `Open()`. ```c# public class CommandFactory { public IDbCommand CreateCommand(IDbConnection connection) { var command = connection.CreateCommand(); connection.Open(); return command; } public async Task Create​CommandAsync(DbConnection connection) { var command = connection.CreateCommand(); await connection.OpenAsync(); return command; } } [TestClass] public class CommandFactoryTests { [TestMethod] public void TestCreateCommand() { // Arrange var commandFactory = new CommandFactory(); var mockConnection = new Mock(); var mockCommand = new Mock(); mockConnection .Setup(mock => mock.CreateCommand()) .Returns(mockCommand.Object); // Act var command = commandFactory.CreateCommand(mockConnection.Object); // Assert Assert.IsNotNull(command); Assert.AreEqual(mockCommand.Object, command); mockConnection.Verify(mock => mock.Open(), Times.Once); } [TestMethod] public async Task TestCreateCommandAsync() { // Arrange var commandFactory = new CommandFactory(); var mockConnection = new Mock(); var mockCommand = new Mock(); mockConnection .Setup(mock => mock.CreateDbCommand()) // problematic line .Returns(mockCommand.Object); // Act var command = await commandFactory.Create​CommandAsync(mockConnection.Object); // Assert Assert.IsNotNull(command); Assert.AreEqual(mockCommand.Object, command); mockConnection.Verify(mock => mock.OpenAsync(), Times.Once); } } ``` The regular variant passed with flying colors. The async variant, on the other hand, failed to compile because `CreateDbCommand()` method in `DbConnection` is `protected`, thus not accessible to the mocking library. The workaround for this is to create an abstract class that derives from `DbCommand` and implement `CreateDbCommand` and return an instance of `Mock`. This can be easily avoided if there's an interface definition that the mocking library can use instead of the abstract class. `DbCommand` has a similar problem, all overloads of `ExecuteReaderAsync()` eventually calls non-mockable `ExecuteDbDataReader()` because it is a `protected` method. Lastly, while I believe I can mock `DbDataReader` easily, it would be great to follow the same hierarchy by having `IDataReaderAsync`. Implementing this will also avoid `IDbCommand` importing `System.Data.Common`. ## Proposed API ```c# public interface IDbConnection { // as-is } public interface IDbConnectionAsync : IDbConnection { new System.Data.IDbCommandAsync Create​Command (); System.Threading.Tasks.Task OpenAsync (); System.Threading.Tasks.Task OpenAsync (System.Threading.CancellationToken cancellationToken); } public abstract class DbConnection : IDbConnectionAsync { ... } public interface IDbCommand { // as-is } public interface IDbCommandAsync : IDbCommand { Task ExecuteNonQueryAsync (CancellationToken cancellationToken); Task ExecuteNonQueryAsync (); Task ExecuteReaderAsync (); Task ExecuteReaderAsync (CommandBehavior behavior); Task ExecuteReaderAsync (CommandBehavior behavior, CancellationToken cancellationToken); Task ExecuteReaderAsync (CancellationToken cancellationToken); Task ExecuteScalarAsync (CancellationToken cancellationToken); Task ExecuteScalarAsync (); } public abstract class DbCommand : IDbCommandAsync { ... } ``` ## Details * The async interfaces should include async public methods defined in the abstract classes but not defined in the base interfaces. * External API changes will be minimal. We can implement `IDbConnection.CreateCommand` and `IDbConnectionAsync.CreateCommand` explicitly on `DbConnection` and maintain `DbConnection.CreateCommand` signature -- it will return the abstract class `DbCommand`. `DbCommand.ExecuteReaderAsync` overloads can use similar approach, albeit with a small hack because of invariant `Task`. * Proposed change diff: https://github.com/dotnet/corefx/compare/master...adriangodong:system-data-async [EDIT] Added C# syntax highlighting by @karelz 20548 area-System.Data [Proposal] It should be possible to manually create SqlException `SqlException` create methods are currently internal.

This means very large files as well as streams like network streams can be read and decompressed on the fly. Basically, the API reads from Stream objects and never seeks on it. This is how the Reader/Writer API from [SharpCompress](https://github.com/adamhathcock/sharpcompress) works. Here's a sample from the unit tests: ```csharp using (Stream stream = new ForwardOnlyStream(File.OpenRead(path))) using (IReader reader = ReaderFactory.Open(stream)) { while (reader.MoveToNextEntry()) { if (!reader.Entry.IsDirectory) { reader.WriteEntryToDirectory(test.SCRATCH_FILES_PATH, new ExtractionOptions() { ExtractFullPath = true, Overwrite = true }); } } } public interface IReader : IDisposable { event EventHandler> EntryExtractionProgress; event EventHandler CompressedBytesRead; event EventHandler FilePartExtractionBegin; ArchiveType ArchiveType { get; } IEntry Entry { get; } /// /// Decompresses the current entry to the stream. This cannot be called twice for the current entry. /// /// void WriteEntryTo(Stream writableStream); bool Cancelled { get; } void Cancel(); /// /// Moves to the next entry by reading more data from the underlying stream. This skips if data has not been read. /// /// bool MoveToNextEntry(); /// /// Opens the current entry as a stream that will decompress as it is read. /// Read the entire stream or use SkipEntry on EntryStream. /// EntryStream OpenEntryStream(); } ``` `WriteEntryToDirectory` is an extension method that provides some shortcuts for dealing with file operations but what it really does is just grab the internal stream and decompresses. The actual entry method is just `IReader.WriteEntryTo(Stream);` If the entry isn't decompressed then the internal stream is just moved forward and not decompressed if possible (some formats require decompression since compressed length can be unknown) The Writer API works similarly. There is also a generic API from `ReaderFactory` or `WriterFactory` that doesn't require knowledge of the format beforehand. There is also a similar `ArchiveFactory` that is writeable (that uses WriterFactory internally to save) that could also be used for the current `ZipArchive` API and beyond. As the author of SharpCompress, I'd like to push a lot of the ideas into core library but having native access to the compression streams (like the internal zlib) would be a great performance benefit for me. I haven't ever written any compression algorithm implementations myself so I'm sure my managed implementations need a lot of love. I would start by creating `ZipReader` and `ZipWriter` (as well as starting the generic API) using a lot of the internal code already in the core library to prove out the API. This kind of relates to https://github.com/dotnet/corefx/issues/14853 but forward-only access is something most libraries don't account for so I'm not sure. Other easy additions would be Reader/Writer support for GZip, BZip2 and LZip (with an LZMA compressor). Tar support linked with the previous single file formats would be a larger addition. SharpCompress deals with `tar.gz`, `tar.bz2` and `tar.lz` auto-magically by detecting first the compressed format then a tar file inside. The above API works the same. Thoughts?

However, it would be nice if the result were a thrown exception or nonsensically sorted sequence instead of an infinite loop to simplify debugging. In comparison, `Array.Sort` applied to the same sequence and `IComparer` does not result in an infinite loop. 20564 area-System.Xml XmlResolver: remove workaround for lack of Unix path support in Uri cc @stephentoub Some tests were relying on the Uri class to convert backslashes to forward slashes. 20570 area-Infrastructure CoreFX contributor experience Forked from discussion in https://github.com/dotnet/corefx/issues/4571#issuecomment-305198456 In nutshell: @FransBouma ran into lots of hardship when trying to contribute to CoreFX repo - mainly around using VS. @jnm2 and @willdean raised similar concerns and additional points. Let's have the discussion here. When there are actionable work items what to fix, or separate larger sub-discussions, we may moved them into separate issues. This issue is forum for the overall problem space. List of key VS scenarios: 1. Require latest stable release of VS (not preview) 1. **Open solution** at the top of the tree 1. **Compile** CoreFX projects, including test projects 2. **Run single test** 1. **Debug single test** (incl. over and over again) 1. **Run all tests** from specific test project so you can confirm things work * P2: Support additional ways to run tests - e.g. ReSharper and NCrunch Ideas: * Integration test of CoreFX build & running/debugging test in VS - note: Can we leverage VS UI test automation? 20574 area-System.Reflection Serialization Backdown shuts down all ParameterInfo serialization, not just the runtime's implementation., The decision to make the runtime’s implementation of Reflection objects non-serializable went too far and changed the behaviors of methods inherited by all Reflection implementors. In particular, by changing ParameterInfo.GetRealObject() to throw PNSE, all third-party implementations of ParameterInfo become undeserializable, not just the runtime’s implementation. The intended change was to make the runtime’s implementation non-serializable which is already accomplished by removing [Serializable] from RuntimeParameterInfo.

The default lock policy on a new keychain is to lock on sleep and after 5 minutes of being idle. This means that if more than 5 minutes pass from usages of a certificate private key (where the cert was opened from a PFX) the user gets prompted for a password for the temporary keychain. Since that keychain has a randomly generated password it's not really possible for the user to accomplish this successfully.

"This change adds a new library, System.Drawing.Common, which supports a large subset of the System.Drawing API. It is a direct port of the code from the .NET Framework codebase. The code has been cleaned, formatted, and sanitized to match the code style of corefx, but is otherwise very similar to the .NET Framework version. There are a few key differences: * TypeConverter's have been omitted for now. If we want to add these to .NET Core, we should add them to the TypeConverter library, rather than System.Drawing.Common itself. Note that there's already a few TypeConverter's for the types that are in System.Drawing.Primitives. * Some parts of the library do not respond to ""System Events"", because they are not yet implemented in .NET Core. This means that fonts and colors will not automatically update when the system defaults change, as they do in .NET Framework. The code is still there, but behind the feature flag ""FEATURE_SYSTEM_EVENTS"". * Various attributes have been removed from the codebase, because they are no longer applicable. Examples: * Designer-related attributes (DefaultProperty, DefaultEvent, Editor, etc.) * CAS-related attributes. CAS-related method calls (Security demands and asserts) have also been removed. There is still further cleanup that can be done in order to match the style and structure of corefx. For example, the interop code should be reorganized to match other BCL libraries. NOTE: This implementation will only work on Windows, and not in UWP. This is a strictly compatibility-driven feature. Any changes made to it should not significantly diverge from the .NET Framework implementation. Libraries should only take a dependency on System.Drawing.Common if they are relying on legacy components from .NET Framework; newly-written code and features should rely on modern alternatives." 20594 area-Serialization Disable Two DCS/DCJS Tests on uapaot.

XmlReader.Create(string) and new XmlTextReader(string) will convert the native file paths to an absolute file:// url and use that as the BaseURI. The other overloads do not convert the url-argument and use it as the BaseURI. On Windows this works fine. Even when not converted to a file:// url, the resulting BaseURI string is treated as an absolute uri to resolve the other uris. On Unix, the overloads that use the url-argument as-is don't work. The BaseURI (e.g. /tmp/myfile.xml) is considered to be a relative url and isn't used to resolve other files. This was observed with failing tests in https://github.com/dotnet/corefx/pull/19735. The difference is due to the Uri class treating absolute file uris as relative on Unix (cfr https://github.com/dotnet/corefx/issues/20046). The tests were updated to pass (https://github.com/dotnet/corefx/commit/3a3ead6abb6c27364f12e41478a34d79ced6fdd1#diff-0bf8d1637c34db29730c199a32fd08ff). This breaks existing code when running on Unix instead of Windows. These can be fixed with changes like the ones made to the tests. To avoid breaking existing code, an option is to convert the url-arguments on Unix so they also become absolute uris. This is implemented in: https://github.com/dotnet/corefx/pull/20561. The PR only changes the behavior on Unix when passing an absolute native file path. @karelz @stephentoub @sepidehMS @krwq 20627 area-Infrastructure Improve Unit Testing experience in CoreFX "I don't want this to be a mass hate-in on xUnit, but I made some unguarded comments about xUnit on another CoreFx thread, and there does seem to be some shared feeling on the subject. @karelz suggested (#4571) in a separate thread to discuss it. If the consensus is 'shove off to the xUnit repo and do your moaning there', then that's fine, though I think my complaints are perceived by some to be positive features of xUnit, so I doubt I'd get any traction on my own. The xUnit issues I have found made testing harder than it needed to be on CoreFx are: * Inability to consistently add messages to assertion methods - you can add a message to `Assert.True`, but you can't to `Assert.Equal`. Two workaround recommendations seem to get made: The first is to use `Assert.True` and put your condition in the `bool` argument - that then means the test runner can put no useful info into the trace. The other alternative is to use a better assertion library (there was some consistency of support for Fluent Assertions, though I haven't used it myself, and my heart sinks at yet another dependency). Every assertion method should have an optional message. People planning to advance the defence at this point that there should only be one assertion in a test and so you shouldn't need messages can expect short shrift from me... * Obvious gaps in the assertion support - e.g. no 'Fail' method, so we end up with stuff like `Assert.True(false, ""Message"")` or writing a helpers to avoid this sort of thing. This would be easy to add. * No proper trace from tests. A .NET test framework/runner should collect Console and Trace output and report/log it sensibly (i.e. not co-mingled with other test output). No ifs, no buts, no excuses about async, nothing. This is the one that really winds me up, because it leads to CoreFx having to have a policy *against* tracing in tests largely because the test outputs gets sprayed across each other so they make no sense. Couple this with the pain some of us have with trying to debug into tests, and the result is miserable - CI post-mortem shouldn't have to be a guessing game. I'm aware that xUnit is somehow the MS-insider's choice, and it was probably the only framework with Core support at the time it was chosen, so we cannot rewrite history, but if the Core projects have any influence with xUnit, could they ask for these improvements? " 20628 area-System.Net Unix paths with backslashes are converted to forward slashes when uri is created with the file scheme "A backslash is a valid character in a unix path. It is not used to separate path segments, it is part of a directory/file name. The Uri class will convert these backslashes to forward slashes, causing the resulting uri to no longer point at the correct file. e.g. `new Uri(file:///one\two)` refers to the `/one/two` instead of `/one\two` When creating a Uri without the file scheme, the Uri class will preserve the backslashes. e.g. `new Uri(/one\two)` refers to `/one\two` Note that the `ToString` of this uri returns `file:///one\two`. Which gives the strange behavior that `new Uri(new Uri(/one\two).ToString())` refers to `/one/two` The Uri class is very persistent in converting backslashes to forward slashes. Even when providing a percent encoded backslash, it is converted to a forward slash. One way to fix this is to no longer convert backslashes for `file:///` uris on Unix. The Uri class has special semantics for two types of files: Dos paths and Unc paths. Dos paths (e.g. c:\) don't start with a slash. Unc paths start with 2 slashes. So paths starting with a single slash can be treated as unix uris (i.e. no forward slash conversion). This is implemented https://github.com/dotnet/corefx/pull/20623. The behavior is only changed on Unix for paths that start with file:/// (3 slashes = 2 slashes of the scheme + 1 slash of the unix path). With the current behavior it is not possible to create a Uri with a file:// argument to refer to a path that contains backslashes. When this behavior is changed, existing code that relied on the backslash-to-forwardslash conversion will break. An example of this can be seen in this PR (https://github.com/dotnet/corefx/pull/20564). Here the implementation was changed from `new Uri(""file://"" + path)` to `new Uri(path)`. Due to slashes no longer being converted, some tests needed changes. @karelz @stephentoub @sepidehMS " 20629 area-System.Collections Remove caching from ImmutableSortedSet.Builder.DebuggerProxy Fix #16007 20630 area-Infrastructure Remove win10/nano RIght now the generators are failing.

So the Activity.Id may have multiple 'nodes' separated by delimiters. Maximum Id length is 1024 and when the limit is reached, last node(s) are trimmed to make space for random overflow suffix. In case there is single node 1024 bytes or longer, overflow if not handled correctly: instead of completely new Id, Activity generated overflow suffix only. This in general is invalid corner case but may happen because of the bug or some compatibility issue. Currently the only problem that overflow suffix is not long enough and does not guarantee global uniqueness of Activity.Id.

Core 2.0 preview 1 now supports SqlDataAdapter and DataTable which is great and the best way to fill a DataSet from a stored procedure is by using SqlDataAdapter.Fill(DataSet). This works perfectly when not used in an async environment. There is currently no way in Core or full .NET to do a FillAsync. Without a FillAsync which would take a single line of code now requires 20 lines of much more complicated code including using SqlDataReader.GetSchemaTable() which is currently broken preview 1. Based on other posts I believe it will be working in Preview 2 but have not seen a definitive on that. This is not something for 2.0 but is a clear deficiency in truly being able to support a fully async back-end and would be a much needed improvement moving forward. 20660 area-System.Net Not able to find Referer property in HttpWebRequest I have portable class library pointing .Net Standard libraries (versions below).

The NotificationAutoEnlist property only checks for data set by ASP.NET, so the property has been removed to show that it's explicitly unsupported. 20709 area-System.Diagnostics S.D.Process: throw PNSE on HWND depending funcs on UAP Fix https://github.com/dotnet/corefx/issues/20619 20710 area-Infrastructure Update buildtools, hook in new Dumpling target * Update buildtools.

Mono's test cases are in this folder: https://github.com/mono/mono/tree/master/mcs/class/System.Drawing/Test We most likely want to convert the most useful tests from all of the sections here, with the exception of System.Drawing.Design, which we aren't going to support right now on .NET Core (it is mainly related to designer / WinForms support). Mono's tests use NUnit, so we will need to convert them to Xunit when copying them. Additionally, I've identified that there will need to be some functional changes made to the tests themselves, as they do not pass against the .NET Framework implementation. We consider the .NET Framework implementation to be the compatibility baseline, so we should change the tests to accomodate it, rather than the other way around. The test failures seemed mainly related to very small, subtle differences in things like floating-point precision, color values, offsets, etc. We should do the following when we have both Windows and Unix implementations up and running: * Ensure that all tests have enough ""leniency"" to accomodate floating-point differences (and other minor inconsistencies) where unavoidable. * Ensure that all minor inconsistencies are acceptable or otherwise very difficult / problematic to fix. * Ensure that all minor inconsistencies are listed somewhere, so that we can mention it both in the tests, and in the user documentation. @hughbe @qmfrederik @marek-safar ----------------------------------------------------- # Current Status Code coverage: _Note that there is a large amount of internal and debug-only code which distorts these numbers.

In order to support the library elsewhere, we are going to port the implementation from mono, which is built around libgdiplus, another mono project. We should do the following: * Move the code for System.Drawing into corefx, perhaps initially separated from the Windows files. Mono's code is here: https://github.com/mono/mono/tree/master/mcs/class/System.Drawing * Update build configurations in corefx to create a second build for System.Drawing.Common for Unix platforms. It should reference the code files above. * In the mono repository: delete the original source files, update the corefx submodule link, and redirect references into the submodule for all of the deleted files. * [Follow-Up] Try to rationalize the Windows and Unix codebases. There is bound to be a moderately-sized chunk of code that can be shared between the two configurations. Enums and simple structures should be identical between the two. @qmfrederik Do you have any pointers for this? I know you have worked extensively with mono's System.Drawing recently. 20713 area-System.Net Disable some Ping tests for UAP test runs System.Net.Ping now runs clean for UAP test runs.

Support for these should be provided in the form of `Fast*` methods exposed on the existing `System.Math` and `System.MathF` types. ### Proposed API ```C# public static class Math { public static double FastClamp(double, double, double); // No intrinsic, but the current implementation requires min <= max, where-as Vector follows what HLSL does public static double FastMax(double, double); // maxsd public static double FastMin(double, double); // minsd public static double FastReciprocal(double); // No intrinsic on x86/x64, provided for parity with MathF public static double FastReciprocalSqrt(double); // No intrinsic on x86/x64, provided for parity with MathF } public static class MathF { public static float Clamp(float, float, float); // Provided for parity with the existing Math.Clamp(float, float, float) function public static float FastClamp(float, float, float); // No intrinsic, but the current implementation requires min <= max, where-as Vector follows what HLSL does public static float FastMax(float, float); // maxss public static float FastMin(float, float); // minss public static float FastReciprocal(float); // rcpss public static float FastReciprocalSqrt(float); // rsqrtss } ``` ### Additional Details This will require several changes in the CoreCLR as well to support the new APIs via intrinsics 20715 area-System.Text Reconcile CoreRT and CoreCLR globalization code ``` -method System.Text.Encodings.Tests.EncodingMiscTests.DefaultEncodingBOMTest -method System.Text.Encodings.Tests.EncodingMiscTests.NormalizationTest -method System.Text.Tests.UnicodeEncodingTests.WebName -method System.Text.Tests.UTF32EncodingTests.WebName -method System.Text.Tests.UnicodeEncodingDecode.Decode_InvalidBytes (amd64 only) ``` On quick glance, the Text.Encoding code in CoreRT needs to be synced with that in CoreCLR. 20716 area-System.IO Fill out FileSystemInfo state when enumerating On Windows FileSystemInfos are filled in with state as we have all of the state from FindFirstFileEx.

You can simply eat all exceptions: ```C# try { await task; } catch { } ``` but that incurs the cost of the throw and also triggers first-chance exception handling. You can use a continuation: ```C# await task.ContinueWith(delegate { }, CancellationToken.None, TaskContinuationOptions.ExecuteSynchronously, TaskScheduler.Default); ``` but that incurs the cost of creating and running an extra task. The best way in terms of run-time overhead is to use a custom awaiter that has a nop GetResult: ```C# internal struct NoThrowAwaiter : ICriticalNotifyCompletion { private readonly Task _task; public NoThrowAwaiter(Task task) { _task = task; } public NoThrowAwaiter GetAwaiter() => this; public bool IsCompleted => _task.IsCompleted; public void GetResult() { } public void OnCompleted(Action continuation) => _task.GetAwaiter().OnCompleted(continuation); public void UnsafeOnCompleted(Action continuation) => OnCompleted(continuation); } ... await new NoThrowAwaiter(task); ``` but that's obviously more code than is desirable. It'd be nice if functionality similar to that last example was built-in. **Proposal** Add a new overload of `ConfigureAwait`, to both `Task` and `Task`. Whereas the current overload accepts a `bool`, the new overload would accept a new `ConfigureAwaitBehavior` enum: ```C# namespace System.Threading.Tasks { [Flags] public enum ConfigureAwaitBehavior { NoCapturedContext = 0x1, // equivalent to ConfigureAwait(false) NoThrow = 0x2, // when set, no exceptions will be thrown for Faulted/Canceled Asynchronous = 0x4, // force the continuation to be asynchronous ... // other options we might want in the future } } ``` Then with `ConfigureAwait` overloads: ```C# namespace System.Threading.Tasks { public class Task { ... public ConfiguredTaskAwaitable ConfigureAwait(ConfigureAwaitBehavior behavior); } public class Task : Task { ... public ConfiguredTaskAwaitable ConfigureAwait(ConfigureAwaitBehavior behavior); } } ``` code that wants to await without throwing can write: ```C# await task.ConfigureAwait(ConfigureAwaitBehavior.NoThrow); ``` or that wants to have the equivalent of `ConfigureAwait(false)` and also not throw: ```C# await task.ConfigureAwait(ConfigureAwaitBehavior.NoCapturedContext | ConfigureAwaitBehavior.NoThrow); ``` etc. From an implementation perspective, this will mean adding a small amount of logic to ConfiguredTaskAwaiter, so there's a small chance it could have a negative imp **Alternatives** An alternative would be to add a dedicated API like `NoThrow` to `Task`, either as an instance or as an extension method, e.g. ```C# await task.NoThrow(); ``` That however doesn't compose well with wanting to use `ConfigureAwait(false)`, and we'd likely end up needing to add a full matrix of options and supporting awaitable/awaiter types to enable that. Another option would be to add methods like NoThrow to ConfiguredTaskAwaitable, so you could write: ```C# await task.ConfigureAwait(true).NoThrow(); ``` etc. And of course an alternative is to continue doing nothing and developers that need this can write their own awaiter like I did earlier. 20733 area-Infrastructure Unit test results presentation is unconventional "![image](https://cloud.githubusercontent.com/assets/1306085/26832554/c7c2878e-4ac7-11e7-89f6-f327ccf8636d.png) The above is a picture of some test results on one of the various CI flavours that's currently in use on CoreFx. I will try to remain polite, but this is completely nuts. * There is a 'fire' emoji (and ""fire"" is what the tool tip says) - does this mean it ran and it failed - i.e. ""Failed""? * There is an empty square - no tooltip - who knows - were these skipped? * And there is an orange checkmark (""skip"" says the tooltip) - does this mean ""Skipped""? All I can say is that I am filled with admiration for the vast creativity and freedom of thought which enables someone to come up with a completely new way to present a passed/failed/skipped table without being shackled by the tedious red/green cross/tick conventions that everyone else uses.

When managed build starts build restores several packages by connecting with Azure blobs. During several builds I have noticed that build failed with error indicating that some of the managed packages were not downloaded due to TimeoutExceptions raised after 60000 ms with no activity on server side. After investigating problem I have found that on Windows laptop I got more than 200 tcp connections open from build to azure blob - with many timing out, and on Mac I have found roughly from 20 to 25 max connections open with some timing out. Due to the fact that I have been traveling lately and have to use LTE connections to get on internet this may be caused by lower quality of network - however this problem happens i.e. in Warsaw, Poland as well, which has very good LTE signal, coverage and transfer rates. My workaround is quite simple and unfortunately tedious - I restart build multiple times until all downloads succeed what eventually happens. My suggestion would be to limit numebr of concurrent opened connections to server (all are going to the same IP) and at the same time introduce robust, exponential retrial algorithm. 20738 area-System.Net Remove default libcurl Content-Type header for empty POST requests Fixes #20734 20739 area-System.Xml Several Xml types use Ref Emit on uapaot which is not supported, which will cause a runtime exception There are several types in System.Private.Xml today that are using types from System.Reflection.Emit which do not exist in UWP. From a quick scan, these types seem to be: ``` System.Xml.Xsl.IlGen.XmlILModule System.Xml.Xsl.XmlIlGenerator ``` Once those two classes are correctly fixed to not use Ref Emit(either by throwing PNS or by different implementation) then we should also fix two things in order to better catch things like this: - Modify the ref of ref emit to not have any types in uapaot(or better yet, don't build it at all). The fact that we are building the contract with the types, is what caused this issue since other implementaitions could reference it. And since we have a baseline today in the implementation project of ref emit for uapaot, the build succeeds. - System.Private.Xml shouldn't have configurations for both uap, and uapaot, and instead just have the one for uap which SHOULD NOT use ref emit. Today, we have the uap config which does use ref emit and expose some other types like CodeGenerator, XmlSerializationILGen, and XmlSerializationReaderILGen that use ref emit as well, and the uapaot config that only has XmlILModule and XmlILGenerator which uses it incorrectly. cc: @sepidehMS @krwq @danmosemsft 20740 area-System.Drawing Finalize packaging for System.Drawing.Common When we have implemented all planned versions of System.Drawing.Common, we should finalize the packaging for the library.

Should be a simple fix. TestNullStream_CopyToAsyncValidation() 20755 area-System.IO File move operation with semantics of Unix rename I am looking for a file move operation with the following characteristics: - Overwrites the destination file if it already exists - Creates the destination file if it does not exist - Replaces the destination file atomically - Never falls back to copying (I want an error if the destination is on a different volume) On Unix, [rename(2)](http://man7.org/linux/man-pages/man2/rename.2.html) meets these, but the BCL doesn't have a direct equivalent. ## Issues with BCL alternatives `File.Replace` * Fails if the destination file does not exist * Unclear if underlying `ReplaceFile` on Windows actually has the right guarantees (*) `File.Move` * Fails if the destination file exists * Can fall back to copying I can almost work around the existence issues as follows: ``` C# if (File.Exists(destination)) { File.Replace(source, destination, null) } else { File.Move(source, destination) } ``` But that's cumbersome and opens the door to classic race between existence check and I/O operation. ## (*) Concern about Win32 ReplaceFile [This page](https://msdn.microsoft.com/en-us/library/windows/desktop/hh802690(v=vs.85).aspx#applications_updating_a_single_file_with_document-like_data) gives me the impression that ReplaceFile is what I want, but then the [API documentation](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365512(v=vs.85).aspx) says the following can happen, which I do not want: >ERROR_UNABLE_TO_MOVE_REPLACEMENT > >The replacement file could not be renamed. If lpBackupFileName was specified, the replaced and replacement files retain their original file names. Otherwise, the replaced file no longer exists and the replacement file exists under its original name. This suggests an implementation in several steps where the backup is required to roll things back, and would not exhibit this desirable behavior of `rename`: > If newpath already exists, it will be atomically replaced, so that there is no point at which another process attempting to access newpath will find it missing. With that said, I was not able to repro this situation, so it may just be that the API documentation is out-of-date with implementation improvements. It is also possible that Windows doesn't offer anything with guarantees as strong as `rename` on Linux. I suspect that on Windows other processes have to be prepared to handle file-in-use errors, so removing file-not-found possibility may not be as useful there. The ideal behavior is that readers see the file before or after the move, with no risk of anything in between. No matter the constraints on Windows, I think it would still be worthwhile to have an API that gives full fidelity to `rename` on Linux and the most reasonable equivalent on Windows... ## Initial API Proposal ``` C# [Flags] public enum MoveOptions { None = 0, ReplaceIfExisting = 1, DisallowCopying = 2, }; public static class File { // existing overload public static void Move(string sourceFileName, string destFileName); // new overload public static void Move(string sourceFileName, string destFileName, MoveOptions options); } public class FileInfo { // existing overload public static void MoveTo(string destFileName); // new overload public static void MoveTo(string destFileName, MoveOptions options); } ``` The existing overloads become equivalent to passing MoveOptions.None to the new overloads. On Windows, the flags can be implemented directly using MoveFileEx, with an open question as to which guarantees of `rename` would (not) be retained. On *nix, each one would amount to disabling part of the emulation of Windows MoveFile. If both are passed, it is basically a straight call to `rename`. 20756 area-Infrastructure Enable Linux Performance Runs Porting changes from master to enable Linux performance runs against release/2.0.0.

Assume the following cases: Rectangle test = new Rectangle (0, 0, 100, 20); Rectangle test2 = new Rectangle(0, 0, 100, 20); bool covered = test.Contains(test2) // will return true as expected bool covered2 = test.Contains(0, 0) // will return true as expected bool covered3 = test.Contains(100, 20) // will return false NOT expected bool covered4 = test.Contains(100, 0) // will return false NOT expected The last cases in my eyes are unexpected, as the documentation for Rectangle.Contains (with the rectangle parameter) states it will return true if it fully covers the given rectangle. In my eyes it would be more intuitive and semantically consistent if the implementation would be changed from public bool Contains(int x, int y) => X <= x && x < X + Width && Y <= y && y < Y + Height; to public bool Contains(int x, int y) => X <= x && x <= X + Width && Y <= y && y <= Y + Height; I know it's a matter of definition what ""Contains"" semantically means. One could find some good arguments why the last two test cases actually are correct. But then we should also discuss the first test case which should be then false as well. So either a Rectangle is fully contained which means also the points (i.e. Rectangle.Right and Rectangle.Bottom) or if those points are not contained then the rectangle itself cannot (should not) be contained as well.

The problem is that once you have a linked cancellation token, it will always be the reported token in any `OperationCanceledException` instead of the actual token that fired. ```C# using System; using System.Threading; namespace ConsoleApp2 { class Program { static void Main(string[] args) { var cts1 = new CancellationTokenSource(); var cts2 = new CancellationTokenSource(); var cts3 = new CancellationTokenSource(); try { cts1.Cancel(); CancellationTokenSource.CreateLinkedTokenSource(cts1.Token, cts2.Token, cts3.Token).Token.ThrowIfCancellationRequested(); } catch (OperationCanceledException ex) { Console.WriteLine(cts1.Token == ex.CancellationToken); } } } } ``` I know it's a breaking change but it's *super* annoying.

When following those instructions the build fails when the SLN file has `\` instead of `/` for the paths in it. The build failure is an `MSB4025` for a missing `.metaproj` file. I suspect many SLN files in the repo have this issue. I'm not sure what the right fix is - I do know that once I changed it to `/` instead of `\` in the SLN it built successfully on linux. This might be an msbuild issue or it might be corefx invalid solutions. Anyway, it would be nice to either update to a msbuild version that fixes this issue or fix the SLN files so that the build/iterate workflow works on linux too. 20829 area-System.Data Add socket connectivity test in the Test TDS server This PR adds a test to connect to the socket when the server initializes the TcpListener to listen to incoming connections before the test can try to connect to the socket.

It has both `void*` and `ref T` overloads for most methods. `void*` overloads for Add and Subtract are missing for no good reason. We ended up writing [our own implementation](https://github.com/dotnet/corefxlab/blob/master/src/System.Buffers.Primitives/System/Buffers/OwnedBuffer.cs#L68-L71) because of the need: ```C# unsafe void* Add(void* pointer, int offset) { return (byte*)pointer + ((ulong)Unsafe.SizeOf() * (ulong)offset); } ``` The Add API is required in System.Buffers.Primitives [Buffer\.Pin](https://github.com/dotnet/corefxlab/blob/master/src/System.Buffers.Primitives/System/Buffers/Buffer.cs#L93-L105) method. ```C# public BufferHandle Pin() { if (_owner != null) { return _owner.Pin(_index); } var handle = GCHandle.Alloc(_array, GCHandleType.Pinned); unsafe { var pointer = OwnedBuffer.Add((void*)handle.AddrOfPinnedObject(), _index); return new BufferHandle(null, pointer, handle); } } ``` ## Open Questions ~- Should the Add/Subtract overload return `ref T` or `void*`?~ ## Pull Request A PR with the proposed changes is available: #20886 ## Updates - Changed return value from `ref T` to `void*`. cc @jkotas, @KrzysztofCwalina, @karelz, @terrajobst 20846 area-System.Runtime Tip: add string.Contains(string, StringComparison) Add convenience API 'string.Contains' overload with `StringComparison` argument.

The build definition puts together VSTS extensions that run the tools, analyze logs, and upload results to Trust Services Automation that creates workitems for identified security issues. List of tools included in this definition are: 1. BinSkim - validates compiler/linker settings and other security-relevant binary characteristics. https://github.com/Microsoft/binskim 2. APIScan - determines whether or not the software complies with the API Usage Standard of the Interoperability Policy. 3. CredScan - index and scan for credentials or other sensitive content. 4. PoliCheck - scan code, code comments, and content for words that may be sensitive for legal, cultural, or geopolitical reasons. Approach followed in this build is: 1. Get NuGet packages corresponding to the specified official build. 2. Extract packages to `$(Build.SourcesDirectory)\security` 3. Run BinSkim and APIScan on the extracted packages 4. Get sources corresponding to the official build. This means checkout at the SHA listed version.txt 5. Run CredScan and PoliCheck on the sources.

I'm running on linux so I don't have VS and don't get the stylecop stuff there. If there was a convenient way to run the style check locally I could be a better citizen and not push things that violate style rules (at least not as often) due to not noticing things or not knowing certain rules - and it would probably make the experience nicer for the reviewers as well, so they could focus on content, not formatting. I'm thinking something like ./stylecop.sh in the root of the repo is the experience I'd be looking for. Other suggestions that were raised were the following workflow: 1. commit your changes 2. run https://github.com/dotnet/codeformatter 3. revert all changes except those in the code you were working on 4. commit formatting fixes or squash into previous commit Of course that whole workflow could be done locally. If this is the sort of workflow we want (I'm fine with that option too), can we make tooling to make it easier as part of the corefx repo? For instance, if (2) could be told how many commits to review and use `git whatchanged HEAD~k` where `k` is the number you provided to figure out which files were touched, that would be awesome. If we want to agree on how changes like this might be done, I can happily help with the git-foo as this is one of my specialties ;) 20876 area-System.IO Directory and file exists methods could be more efficient Related to #19717 Exists methods have a try-catch for error cases and they normalize, which is not necessary (at least on Windows). As all error cases return false, we can remove most of this overhead. https://github.com/dotnet/corefx/blob/master/src/System.IO.FileSystem/src/System/IO/File.cs#L181-L210 The only pre-emptive check we might want to keep from GetFullPath is to return false if the passed in path contains an embedded null. Maybe have a `FileSystem.FileExistsFast`? This is the current Windows one: https://github.com/dotnet/corefx/blob/master/src/System.IO.FileSystem/src/System/IO/File.cs#L181-L210 Unix is already in much better state. I assume that crappy and partial (relative) paths will work. Tests for bad and relative paths are critical, need to validate existing coverage and expand if necessary. 20878 area-Infrastructure Enable two new queues (Suse SLES 12) and (Fedora 26) Suse SLES 12 and Fedora 26 need to be supported for Core 2.0 as well: https://github.com/dotnet/core-eng/issues/861 They ran well in staging, now enable them in Prod corefx official runs. 20879 area-Serialization Using mscorlib shim as default resolving assembly for BinaryFormatter serialization instead of System.Private.Corelib If a type gets serialized in netfx which lives in mscorlib the serialized blob won't contain the Assembly Information (because mscorlib is special cased to remove unnecessary blob info):  System.Collections.Comparer CompareInfo System.Globalization.CompareInfo  System.Globalization.CompareInfom_name win32LCID culture m_SortVersion System.Globalization.SortVersionen-US  ` BinaryFormatter checks if that is the case here: https://github.com/dotnet/corefx/blob/0ebc867d6bad9d777dd61afb78d0445c86143b34/src/System.Runtime.Serialization.Formatters/src/System/Runtime/Serialization/Formatters/Binary/BinaryParser.cs#L430-L435 and will use the default assembly for resolving the type. In netfx the default assembly is mscorlib.dll because it gets checked by `typeof(string).Assembly`. In Core this is System.Private.Corelib.dll which doesn't contain all the types which are living in mscorlib in netfx. Therefore we should change the default assembly to the mscorlib shim which contains manual and auto-generated TypeForwards. The `Assembly.Load(string)` call should also work in uap/uapaot as the mscorlib shim is already loaded. This fixes e.g. that the correct System.Collections.Comparer is picked when trying to deserialize in core. Before this change this one was resolved (internal) https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Collections/Comparer.cs instead of this one (public) https://github.com/dotnet/corefx/blob/master/src/System.Runtime.Extensions/src/System/Collections/Comparer.cs Thanks @ericstj ## Optimization This PR also improves the serialization payload dramatically and brings it pack on pair with netfx.

This new issue is specifically about new API that needs to be added in .NET Core that does not (yet) exist in .NET Framework. `DbProviderFactories` on .NET Framework can only be initialized from .config files, and in order to make the API usable without .config files the new API is needed. The proposal by @FransBouma can be found in https://github.com/dotnet/standard/issues/356#issuecomment-307552750 and is repeated below: I've refactored the code a bit, the new API now looks like: ```cs public static void ConfigureFactory(Type providerFactoryClass); public static void ConfigureFactory(Type providerFactoryClass, string providerInvariantName); public static void ConfigureFactory(Type providerFactoryClass, string providerInvariantName, string name, string description); public static void ConfigureFactory(DbConnection connection); public static void ConfigureFactory(DbConnection connection, string providerInvariantName); public static void ConfigureFactory(DbConnection connection, string providerInvariantName, string name, string description); ``` Two new overloads are added. They'll use the fallback code for the providerInvariantName, as it is also present in netfx' auto-init code: it will use the namespace of the type. I've added this to avoid people making a typo in the name as for most factories I know (I don't really know of a dbproviderfactory where this isn't the case) the invariant name is equal to the namespace. ### Method usage / purpose ```cs public static void ConfigureFactory(Type providerFactoryClass) ``` **Description**: This method will register the factory instance contained in the specified type, under invariant name equal to the namespace of the specified type. It will leave name and description empty. **Purpose:** This method is meant to be the easiest way to register a factory. Most (if not all) ADO.NET providers use as invariant name the namespace of the factory type. ```cs public static void ConfigureFactory(Type providerFactoryClass, string providerInvariantName) ``` **Description**: This method will register the factory instance contained in the specified type, under invariant name specified in providerInvariantName. It will leave name and description empty. **Purpose:**: This method can be used to register a factory for the ADO.NET providers which don't use the namespace as the invariant name, and it can also be used to register a different factory type under a well-known invariant name, e.g. in the case of a wrapping factory for ADO.NET profiling. ```cs public static void ConfigureFactory(Type providerFactoryClass, string providerInvariantName, string name, string description) ``` **Description**: This method will register the factory instance contained in the specified type, under invariant name specified in providerInvariantName and will fill in the name and description values for the factory. **Purpose:**: This method is equal to `ConfigureFactory(type, string)` and can be used to fill in the additional two columns in the factory table if a user requires that. ```cs public static void ConfigureFactory(DbConnection connection) ``` **Description**: This method will register the factory instance obtained from the specified connection, under invariant name equal to the namespace of the factory instance's type. It will leave name and description empty. **Purpose:** This method is meant to be the easiest way to register a factory if the user doesn't know the factory type but does know the connection type. As DbProviderFactory registration was mainly hidden for most users it can very well be they're not familiar with the factory types, so this method and its overloads make it easier for them to register a factory. Most (if not all) ADO.NET providers use as invariant name the namespace of the factory type. ```cs public static void ConfigureFactory(DbConnection connection, string providerInvariantName) ``` **Description**: This method will register the factory instance obtained from the specified connection, under invariant name specified. It will leave name and description empty. **Purpose:**: This method can be used to register a factory for the ADO.NET providers which don't use the namespace as the invariant name, and it can also be used to register a different factory type under a well-known invariant name, e.g. in the case of a wrapping factory for ADO.NET profiling. ```cs public static void ConfigureFactory(DbConnection connection, string providerInvariantName, string name, string description) ``` **Description**: This method will register the factory instance obtained from the specified connection, under invariant name specified in providerInvariantName and will fill in the name and description values for the factory. **Purpose:**: This method is equal to `ConfigureFactory(DbConnection, string)` and can be used to fill in the additional two columns in the factory table if a user requires that. 20904 area-Serialization Fixing BinaryFormatter member names of parent members to align with netfx @ericstj @stephentoub @danmosemsft @morganbr This is the fix to the offline discussion.

I've not done anything to minimize allocations / improve perf, etc., as that can be done in the future, and the results of all of this gets cached. Changing this required regenerating a few of the serialization blobs in the tests.

20991 area-Microsoft.CSharp Step 1 of fix for disabled System.Dynamic.Runtime test on ILC (https://github.com/dotnet/corefx/issues/19895) Make Microsoft.CSharp use the the real HasMetadataDefinitionAs() api if it exists on the running framework. Since this library is built on netstandard, it still needs to fall back on its emulation on older frameworks. Actual removal of the ActiveIssue will have to wait until the new System.Runtime reference assembly propagates to the Project N tree and the new api becomes reflectable. 20992 area-System.Net Disable tests in System.Net.Requests for UAP Disable tests related to RemoteExecutor which still doesn't work in UAP. This PR results in a clean UAP test run for System.Net.Requests. Contributes to #20136 20994 area-System.Net CoreFX is more restrictive parsing if-match header values than the equivalent with the FullCLR. "One of our customers, nmbradford, is moving to PowerShell 6 from Windows PowerShell and has hit an incompatibility between CoreFX and FullCLR's handling of if-match header values. For example, the following Works on Windows PowerShell: ``` $headers = @{} $headers.Add(""if-match"",""12345"") Invoke-WebRequest -Uri ""http://httpbin.org/headers"" -Headers $headers ``` On PowerShell 6 with the CoreFx, the same results in a FormatException thrown by `System.Net.Http.Headers.HttpHeaderParser.ParseValue`. His expectation is the header value should work on PowerShell/CoreFx as it does with Windows PowerShell/FullCLR. Instead, he needs to special case this header for it to work. See https://github.com/PowerShell/PowerShell/issues/2895 for the related PowerShell issue." 20997 area-Infrastructure Helix-based CI runs are not flagging test failures Example: https://ci3.dot.net/job/dotnet_corefx/job/master/job/portable-windows-Config_Debug+OuterLoop_false_prtest/773/ This job is labeled a success, but there are many test failures if you look deeper into the results. @MattGal @karajas @weshaggard 21001 area-System.Net Disable tests in System.Net.Mail for UAP Disable tests related to RemoteExecutor which still doesn't work in UAP.

So I think the problem is specific to using a loopback TLS/SSL server within the UAP tests which use app-container.

DeflateStream Performance test 21051 area-System.Net Minor perf improvements to Sockets Shaves a few percent off various socket operations. It's close to noise, but appears to be statistically significant and amount to around 2-3% improvement in microbenchmarks that repeatedly receive/send (in which case receives complete asynchronously) and send/receive (in which case most if not all operations complete synchronously). (At this point most of the overhead associated with sockets (at least in the Windows build) is either in the P/Invokes to native or in peanut butter spread across lots of functions with very low exclusive amounts per function. There's likely a decent amount more to be done on Linux, where we've done less profiling and where we know there are improvements to be made around asynchronous completion and dispatch.) cc: @geoffkizer, @cipop, @davidsh, @vancem 21052 area-System.Collections Please provide ref indexer for collection builder types For example `ImmutableArray.Builder`. Note: https://github.com/dotnet/csharplang/issues/476 could make this a lot cleaner. Also related: https://github.com/dotnet/csharplang/issues/461 21053 area-System.Numerics BigInteger should have a less strictly typed constructor "`BigInteger` should have a `public BigInteger(IList)` constructor instead of the existing `public BigInteger(Byte[])` constructor. ### Rationale First, asking for an interface instead of a specific type seems more in line with the ideology of the language. Second, there are situations when this would have been more convenient. As an example, we are implementing some public key cryptosystems and use big integers internally. Many PK cryptosystems ([example](https://en.wikipedia.org/wiki/ElGamal_encryption#Encryption)) produce ciphertexts that are actually a pair of big integers, which are stored as a single concatenated byte array; e.g., a `byte[96]` stores two big integers, 48 bytes long each. Reconstructing these would require an extra step of copying first and second halves of the array into individual arrays — an expensive operation. These add up when we are processing large data sets. Especially, considering that modern PK cryptosystems often work with ciphertexts 256 or 512 bytes long. Instead, if there was an `IList` constructor, we could have used `ArraySegment` and skip an unnecessary array copying. ### Details `BigInteger` from `System.Numerics` could be ""serialized"" to a byte array using `.ToByteArray()` method, and ""deserialized"" from a byte array using one of the constructors. However, currently, it only has a constructor that takes `byte[]`. Since the constructor (according to the [reference source](https://referencesource.microsoft.com/#System.Numerics/System/Numerics/BigInteger.cs,531)) actually only uses `.Length` property and indexed access, it would have been enough to require `IList` as an argument. The proposal is to replace an existing constructor with `public BigInteger(IList)`. Since `byte[]` implements `IList`, I don't see any compatibility issues that could arise from that change. As I understand, just adding it to the list of constructors would create ambiguity, but I didn't verify that. Hopefully, this could also be backported to the .NET Framework." 21054 area-System.Runtime Replace ActiveIssue with PlatformDetection.IsSupported So I can close that issue. And if we ever change our mind, the tests will light up. Fixes https://github.com/dotnet/corert/issues/3743 21055 area-System.Collections Proposal: Specialize IA.Builder.ToImmutableArray, IHS.Builder.ToImmutableHashSet "A while ago I was working on a project and whenever I wanted an `ImmutableArray` I would just call `ToImmutableArray()` on the enumerable. I got so used to doing this, in fact, that I did it for `ImmutableArray.Builder`s without realizing there was a `ToImmutable()` method for a long time. ## Update 8/13/17 Instead of making the new facades instance methods, they will be extension methods. Rationale is given in [this comment](https://github.com/dotnet/corefx/issues/21055#issuecomment-317918406). ```cs public static class ImmutableArray { public static ImmutableArray ToImmutableArray(this ImmutableArray.Builder source); } public static class ImmutableDictionary { public static ImmutableDictionary ToImmutableDictionary(this ImmutableDictionary.Builder source); } public static class ImmutableHashSet { public static ImmutableHashSet ToImmutableHashSet(this ImmutableHashSet.Builder source); } public static class ImmutableList { public static ImmutableList ToImmutableList(this ImmutableList.Builder source); } public static class ImmutableSortedDictionary { public static ImmutableSortedDictionary ToImmutableSortedDictionary(this ImmutableSortedDictionary.Builder source); } public static class ImmutableSortedSet { public static ImmutableSortedSet ToImmutableSortedSet(this ImmutableSortedSet.Builder source); } ``` ## Update 6/16/17 We can add `IA.Builder.ToIA()`, `IHS.Builder.ToIHS()`, etc. instance methods that are simply wrappers for `ToImmutable()`, preventing people who make silly mistakes like me from degrading the performance of their app. ```cs public struct ImmutableArray { public class Builder { public ImmutableArray ToImmutableArray(); } } public class ImmutableHashSet { public class Builder { public ImmutableHashSet ToImmutableHashSet(); } } // ... ``` ## Original content It might be a good idea to add `ToImmutableArray()` to `ImmutableArray.Builder` and mark it `[Obsolete]`, for the sake of enforcing consistency. Similar for all of the other builder types. The `[Obsolete]` should not have `error: true` because we don't want to break existing code, but it will advise the user to use `ToImmutable()`. ```cs public struct ImmutableArray { public class Builder { [EditorBrowsable(Never)] [Obsolete(""Use ToImmutable() instead."")] public ImmutableArray ToImmutableArray(); } } public class ImmutableHashSet { public class Builder { [EditorBrowsable(Never)] [Obsolete(""Use ToImmutable() instead."")] public ImmutableHashSet ToImmutableHashSet(); } } // ... ``` /cc @AArnott, what do you think?" 21056 area-System.Diagnostics Store Activity wrapped into ObjectHandle in Logical CallContext Request to merge https://github.com/dotnet/corefx/pull/20963 into releae/2.0.0 Addresses #21027 **Is not approved by shiproom so far** 21057 area-System.Net Socket SelectTest.Poll_NotReady() fail in ILC mode due to metadata removed for performance reason System.Net.Sockets tests run fine in F5 ('uap') mode. But in ILC ('uap-aot') mode they are failing. It seems that the metadata the test needs to look up has been removed: ```c# [Theory] [InlineData(SelectMode.SelectRead)] [InlineData(SelectMode.SelectError)] public void Poll_NotReady(SelectMode mode) { KeyValuePair pair = CreateConnectedSockets(); try { Assert.False(pair.Key.Poll(SmallTimeoutMicroseconds, mode)); } finally { pair.Key.Dispose(); pair.Value.Dispose(); } } ``` We get failures like this: >System.Reflection.MissingMetadataException : This operation cannot be carried out because metadata for the following object was removed for performance reasons:\n\n System.Net.Sockets.SelectMode\n\nNo further information is available. Rebuild in debug mode for better information.\n\n Is this an expected problem from the UWP test runner in ILC mode?

Looking at the source of `NewExpression`, it does not seem to be possible to define a `NewExpression` without ctor (even need to pass the default parameterless one). So the Expression tree created looks incorrect. Instead of `new DateTime` if `new Post` is used then property has default ctor. So this seems to be specific to DateTime only (or may be other similar system types) ``` PM> dotnet --info .NET Command Line Tools (2.0.0-preview2-006443) Product Information: Version: 2.0.0-preview2-006443 Commit SHA-1 hash: 3a5612f153 Runtime Environment: OS Name: Windows OS Version: 10.0.15063 OS Platform: Windows RID: win10-x64 Base Path: C:\Users\smpatel\.dotnet\x64\sdk\2.0.0-preview2-006443\ Microsoft .NET Core Shared Framework Host Version : 2.0.0-preview1-002111-00 Build : 1ff021936263d492539399688f46fd3827169983 ``` " 21062 area-System.Net ILC mode will clear out ParamName for ArgumentNullException "System.Net.Sockets NullArgs_Throw() test runs fine in netcore/netfx/uap mode.

The test failed on uapaot when using sg.exe because sg.exe couldn't pre-generate correct serializer for the test type. It's hard to fix sg.exe to make it generate proper serializer for the type. But since the reflection-base serialization worked for the test type, the workaround is to let sg.exe not to generate serializer for the type and to use reflection-based serialization at runtime. And this would be the workaround we recommend to developers to deal with types having issues like #19897 .

Then we found a regression in this .NET Core version -- the call to `ResourceManager.GetString(string)`, which worked fine on .NET Core `2.0.0-preview1-002106-00`, starts to throw `System.IO.FileNotFoundException`. Impact -------- This is a blocking issue for us. It basically breaks PowerShell core. Repro ------ An application that reads a resource string from a DLL ```CSharp using System; using System.Diagnostics; using System.Reflection; using System.Resources; namespace temp { class Program { static void Main(string[] args) { if (args.Length != 3 && args.Length != 4) { Console.WriteLine(""Usage: test.exe [-debug]""); return; } var path = args[0]; var rName = args[1]; var rKey = args[2]; if (args.Length == 4) { Console.WriteLine(""PID: {0}"", Process.GetCurrentProcess().Id); Console.ReadKey(); } Console.WriteLine(""Assembly:\n\t-- {0}"", path); Console.WriteLine(""Resource:\n\t-- {0}"", rName); Console.WriteLine(""StringKey:\n\t-- {0}"", rKey); Assembly asm = Assembly.LoadFrom(path); var rm = new ResourceManager(rName, asm); try { string rStr = rm.GetString(rKey); Console.WriteLine(""\n{0}:\n\t-- {1}"", rKey, rStr); } catch (Exception ex) { Console.WriteLine(""\n!!! {0} Caught:\n\t-- {1}"", ex.GetType().FullName, ex.Message); } } } } ``` `Lib.dll` is an example assembly that is built against .NET Core `2.0`. We can see the embedded resource files in `ildasm` as follows: ![image](https://user-images.githubusercontent.com/127450/27194987-a0135e68-51b9-11e7-888f-bc94348549ce.png) The project to build `Lib.dll` is also attached for your reference: [Lib.zip](https://github.com/dotnet/corefx/files/1078517/Lib.zip) Run the application to get a resource string: ```CSharp dotnet run C:\tmp\Lib.dll Lib.Resources.CsvCommandStrings CannotSpecifyPathAndLiteralPath ``` Expected Behavior -------------------- With .NET Core `2.0.0-preview1-002106-00` (using .NET Core SDK `2.0.0-preview1-005952`), the resource string corresponding to the key `CannotSpecifyPathAndLiteralPath` is retrieved back: ``` PS:34> dotnet run C:\tmp\Lib.dll Lib.Resources.CsvCommandStrings CannotSpecifyPathAndLiteralPath Assembly: -- C:\tmp\Lib.dll Resource: -- Lib.Resources.CsvCommandStrings StringKey: -- CannotSpecifyPathAndLiteralPath CannotSpecifyPathAndLiteralPath: -- You must specify either the -Path or -LiteralPath parameters, but not both. ``` Actual Behavior ----------------- With .NET Core `2.0.0-preview2-25407-01`, `System.IO.FileNotFoundException` is thrown by `ResourceManager.GetString(string)`: ``` PS:47> dotnet run C:\tmp\Lib.dll Lib.Resources.CsvCommandStrings CannotSpecifyPathAndLiteralPath Assembly: -- C:\tmp\Lib.dll Resource: -- Lib.Resources.CsvCommandStrings StringKey: -- CannotSpecifyPathAndLiteralPath !!!

For example 0xA0 is allowed as end char on NTFS. This can cause problems, as described [here](https://github.com/PowerShell/PowerShell/issues/4017). I think the same is with char 0x85.

Currently the manual shims for mscorlib and System are resolving references from RuntimePath (https://github.com/dotnet/corefx/blob/master/src/shims/manual/mscorlib.csproj#L25), which is correct on individual vertical builds but as part of the AllConfigurations leg it will always be netcoreapp which means the shims for the other configurations (currently only uap) will not have the correct type-forwards. Given we don't ship them from that build leg this isn't a blocker but we need to fix this to ensure we produce the same assets in the AllConfigurations mode that we do in the individual vertical legs. cc @ViktorHofer @ericstj 21104 area-System.Net Fix System.Net.NetworkInformation.Tests for uap This tests where writing files to the test directory and since Uap tests run inside appx this is not authorized so they where failing.

After the changes are done we should have the following CI legs PR: ``` CROSS Check OSX x64 Debug Build OSX x64 Release Build Linux x64 Debug Build Linux x64 Release Build Windows x64 Debug Build Windows x64 Release Build NetFx Debug Build NetFx Release Build UWP CoreCLR Debug Build UWP CoreCLR Release Build UWP NETNative Debug Build UWP NETNative Release Build All Configurations Debug Build All Configurations Release Build Tizen armel Debug Build Tizen armel Release Build Ubuntu14.04 arm Release Build Ubuntu16.04 arm Debug Build ``` By default a leg will run inner loop tests only and be targeting .NET Core portable binaries, unless a different configuration is specified (i.e. netfx, uwp, all). Each of these legs will also support an outerloop trigger by prepending the leg name with ""Outerloop"" for folks that need to manually trigger outerloop test runs. The only .NET Core non-portable legs we currently have is Tizen armel and Ubuntu arm @hqueue @jyoungyun Do we still need all those legs or is the Tizen leg enough?

After some discussion with @geoffkizer @stephentoub @jkotas and others we believe that it is a straightforward solution that solves the race. It looks much like what the code WAS like (thus reverting this change would be a good starting point), but on close it will hand off to the polling thread the responsibility of freeing the GCHandle. 21149 area-System.IO Clean up attribute code - Cleans up and optimizes file attriubte retrieval - Adds wrapper for disabling media prompt and wraps correctly in enumerator This is backlog work that is important for taking the next steps to removing our WinRT code. 21151 area-System.Threading System.Threading.Tests.MutexTests hanging in Uap "This two tests are hanging in uap: CrossProcess_NamedMutex_ProtectedFileAccessAtomic AbandonExisting Sorce code: https://github.com/dotnet/corefx/blob/master/src/System.Threading/tests/MutexTests.cs#L142-L201 They both hang when calling `new Mutex(false, name)` and the name contains `""Global\\""` as its prefix. cc: @kouvel @AntonLapounov" 21152 area-System.Threading Disable System.Threading Mutex hanging tests This two tests are hanging and we are not getting test results.

But in ILC ('uap-aot') mode they are failing. It seems that the array initialization throws ArgumentOutOfRangeException if size is 0 (take one test for example): ```c# [Theory] [InlineData(SocketImplementationType.APM)] [InlineData(SocketImplementationType.Async)] public void EmptyBuffer_Ignored(SocketImplementationType type) { SendPackets(type, new SendPacketsElement(new byte[0]), 0); } ``` SendPackets() will eventually call into `SetupPinHandlesSendPackets()` in `SocketAsyncEventArgs.Windows.cs` ```c# private unsafe void SetupPinHandlesSendPackets() { ... _sendPacketsDescriptor = new Interop.Winsock.TransmitPacketsElement[_sendPacketsElementsFileCount + _sendPacketsElementsBufferCount]; // throws ArgumentOutOfRangeException if size is 0, i.e _sendPacketsElementsFileCount + _sendPacketsElementsBufferCount == 0 ... } ``` If _sendPacketsElementsFileCount + _sendPacketsElementsBufferCount == 0, we get failures like this: >System.ArgumentOutOfRangeException : Specified argument was out of the range of valid values.

On the other hand, SqlClient has been instrumented with `DiagnosticSource`. I talked to @vancem today and we came to the conclusion that there may be enough value in standardizing on `DiagnosticSource` before we release 2.0. This would make the story more consistent for consumers of ADO.NET events (we are planning to add more `DiagnosticSource` instrumentation and make it easier for ADO.NET providers to add it) and once we ship the `EventSource` instrumentation it is unlikely that we will be able to remove it. cc @saurabh500 21162 area-System.Xml Fix System.Xml.Xsl.XslTransformApi.Tests in uap This tests where crashing because they had ~1300 failures in uap and we currently dump all the failures to the app runner's UI so that 1300 stack traces where blowing up the runner and crashing.

This means that `PngFrame()` won't be called if `_iconData == null`, so the check is dead inside `PngFrame`.

------ There is a https://curl.haxx.se/libcurl/c/CURLOPT_TCP_KEEPALIVE.html that could possibly be set in a world where `ServicepointManager.SetTcpKeepAlive` is back in play. Will this make a comeback in netstandard 2.0? Not sure that that curl opt will improve things though. 21230 area-System.Security Make VerifyWithRevocation skip if the Online chain can't build "When the system doesn't have a current CRL cached for the entirety of the chain, and the CRL Distribution Point is offline (or there's a local network issue) then the test fails. This is tolerable for a manual run, but not for the automated runs. So unless the X.509 ""RunManualTests"" configuration is set, treat a failure of the online chain to be a skip. Ideally we'd throw a SkipTestException, or something of that ilk, but xunit doesn't support it. Fixes #21076 (in master)" 21231 area-System.Runtime User Environment variable tests should pass on uap/uapaot On the RS3 images, get/set of user environment variables should work and the tests should be enabled. get/set of machine environment variables will be blocked by appcontainer and the tests shoudl be disabled for uap/uapaot. 21232 area-System.Net Add managed HttpClientHandler prototype as opt-in @geoffkizer prototyped out a managed HttpClientHandler implementation, as we'd eventually like to be able to switch to a managed implementation as the primary implementation rather than having different implementations per platform. It's missing features (e.g. HTTP/2, various auth support, etc.), needs work around correctness and performance, etc., but it's at a good enough state to check-in and enable under a feature flag in an opt-in fashion, which will allow everyone to help contribute to it and make it better. The first commit adds Geoff's code. The second integrates it into HttpClientHandler in an opt-in manner, such that by default on Windows you still use WinHttpHandler and on Unix CurlHandler, but by setting an environment variable, you can opt-in to experiment with the managed implementation. The commit also enables some of the tests to also run with the managed handler; the rest can be enabled when some issues are fixed. (As part of this PR, I'm not planning to address any issues with the managed implementation. Folks are welcome to submit PRs to do so subsequently.) cc: @geoffkizer, @davidsh, @cipop, @wfurt, @Priya91, @Petermarcu 21233 area-System.Net Regression in System.Net.Primitives for UWP Running the UAP tests I'm getting the following for System.Net.Primitives: ``` 0:017> !pe Exception object: 0000018080001210 Exception type: System.ExecutionEngineException Message: InnerException: System.Diagnostics.Debug+DebugAssertException, Use !PrintException 0000018080638d88 to see more.

This issue has been there forever and is particularly problematic for value-type/struct values which are extensively used in game dev. Value updates require the whole struct to be copied, changed and reinserted (copied again) with another lookup. The C#7 ref feature allows one to create faster custom dictionaries without messing with Entry indexes, but why not fix the Dictionary in the coreclr? The following Dictionary methods are needed to prevent double lookups in checks & updates and insertions: public ref TValue GetValueByRef(TKey key) // throws if key not found private static TValue _DefaultVal; // needed for TryGetValueByRef as default return public ref TValue TryGetValueByRef(TKey key, out bool found) public ref TValue TryGetValueByRefOrAdd(TKey key, out bool found, TValue setVal) public bool TryGetValueOrAdd(TKey key, out TValue value, TValue setValue) Furthermore I propose incrementing the `version`-field (used by enumerators) only when Entries are added or removed, but not when they are changed because it serves no purpose. Reference-type values can already be changed without the Dictionary knowing and incrementing the version. 21241 area-Serialization Add automation tests for SGEN. Add automation tests for SGEN.

Both of these are slow. Typically what people actually do is call ToString, which forces the creation of a large string. Often the very next thing that happens is that the String is written to a file, leaving behind a large, dead string on the GC heap. With the advent of Span there is now an efficient, safe mechanism for extracting the data in the StringBuilder. The proposed API is ```c# /// /// ForEachChunk is an efficient way of accessing all the characters in the StringBuilder. /// It is an alternative to calling ToString() on the StringBuilder. /// /// The 'callback' delegate is called 0 or more times, each time being passed a chunk of /// the string as a ReadOnlySpan of characters (in order). This is repeated until all /// the characters in the span have been passed back through 'callback'. /// /// A method that is called repeatedly, being passed a chunk /// of the Strinbuilder with each call. If 'false' is returned by the callback /// then ForEachChunk terminates immediately. public void ForEachChunk(Func, bool> callback) ``` The actual implmentation is simple: ```c# public void ForEachChunk(Func, bool> callback) { VerifyClassInvariant(); ForEachChunk(callback, this); } private bool ForEachChunk(Func, bool> callback, StringBuilder chunk) { // The chunks are last written first, so we need to output the others first. var next = chunk.m_ChunkPrevious; if (next != null && !ForEachChunk(callback, next)) return false; // The fields here might be changing and inaccurate if threads are racing, but the validation that Span does on // construction insures that the values, even if inaccurate, are 'in bounds'. return callback(new Span(chunk.m_ChunkChars, chunk.m_ChunkOffset, chunk.m_ChunkLength)); } ``` The intent is that this new API can be a building block to provide extension methods on Stream (or other APIs that act like streams) that operate on StringBuilders directly (so an intermediate strings need not be formed) Question: A variation of this is to have an explicit context parameter that is passed to the callback. ```c# public void ForEachChunk(Func, T, bool> callback, T context = null) where T : class ``` While this is not as convenient to use, it allows the user to avoid creating closures (which force the allocation of a Func), which is faster (and the goal of this API is is all about being faster) @stephentoub @jkotas @alexperovich @AlexGhiondea @davidfowl " 21250 area-System.Net CookieContainer has issues with cookies set to a different path than the current request uri path When a server sends back a cookie with a path different than the current request uri, CookieContainer throws an exception indicating that the path portion of the cookie is invalid. For example: * HttpClient send a request to `/Home/About` * The server answers with a redirect response to `/tfp/Identity/signinsignup/...` and sets a cookie to `/signin-oidc` * Internally, CookieContainer throws or silently fails on line https://github.com/dotnet/corefx/blob/master/src/System.Net.Primitives/src/System/Net/Cookie.cs#L508 I believe this is due to the fact that an old version of the spec required any path on any cookie set by the server to be a prefix path of the current request URI. This doesn't seem to be the case in the latest version of the standard. https://tools.ietf.org/html/rfc6265 (new version) https://tools.ietf.org/html/rfc2109 (old version) For reference, this works fine on all major browsers (Chrome, Firefox, Edge,...) We ran into this on our authentication tests (that run the scenario mentioned above). Limiting the path check in the code linked above to only the case when the cookie refers to an old version of the spec should be enough. 21252 area-Infrastructure TargetsWindows msbuild property is false for netfx configuration "For the `netfx` configuration, `'$(TargetsWindows) == 'false'` However, we can use the `netfx-Windows_NT` configuration instead, and `'$(TargetsWindows) == 'true'` Is this expected?

CC @Priya91 @stephentoub @karelz 21267 area-Meta Command Line tokenization is done all over the place and inconsistently. They should be reconciled. "We have at least four separate implementations of command line tokenization/pasting: CoreCLR - Windows - **Environment.GetCommandLineArgs()** and create a String[] array to pass to Main() https://github.com/dotnet/coreclr/blob/master/src/utilcode/util.cpp#L2886 CoreRT - Windows - **Environment.GetCommandLineArgs()** and create a String[] array to pass to Main() https://github.com/dotnet/corert/blob/master/src/System.Private.CoreLib/src/System/Runtime/CommandLine.Windows.cs#L44 CoreFx - Unix - **System.Diagnostics.Process** - create String[] array to pass to Unix exec(). https://github.com/dotnet/corefx/blob/master/src/System.Diagnostics.Process/src/System/Diagnostics/Process.Unix.cs#L450 CoreFx - AnyPlatform - **Environment.CommandLine** - untokenize String[] array back to a single String. https://github.com/dotnet/corefx/blob/master/src/System.Runtime.Extensions/src/System/Environment.cs#L64 There's also test infrastructure (https://github.com/dotnet/corefx/blob/master/src/CoreFx.Private.TestUtilities/src/System/Diagnostics/RemoteExecutorTestBase.Process.cs#L52) which implements a ""String[]""-based process invocation utility. It should also paste the arguments using the canonical standard but right it now, it doesn't even make a minimal attempt. While we can't easily share source for an algorithm that lives in three different repos and is written in two different languages, they should at least implement the same standard. It's a pity we never API'ized this in a usable way since every command line tool that parses a response file has to redo this work (and probably get it wrong.) That standard should probably be the CRT's **parse_cmdline()** routine which is what the full framework has emulated ever since .Net 4.0. The CoreCLR and CoreRT implementations are probably already good reference implementations to model (aside from some incorrect comments that imply the behavior is based on **CommandLineToArgvW()**. That may have been true once, but that behavior has diverged between it and the CRT.) The Unix tokenizer at has at least one bug related to zero-length arguments. And the repaster for Environment.CommandLine looks highly suspect (does not recognize that argv[0] is tokenized using special rules, and handling of the 2N/2N+1 backslash rule.) For reference here's also a good 3rd party overview of the sorry mess: http://www.windowsinspired.com/how-a-windows-programs-splits-its-command-line-into-individual-arguments/" 21268 area-System.Runtime Disable User and Machine environment api tests inside appcontainers.

This is tolerable for a manual run, but not for the automated runs. So unless the X.509 ""RunManualTests"" configuration is set, treat a failure of the online chain to be a skip.

We should add them back behind a flag, because mono needs them to stick around when they compile this code. @hughbe 21271 area-Infrastructure Build definition work to disable external publish via PipeBuild definition "Related: https://github.com/dotnet/core-eng/issues/626 This was informed by the MSRC work, where being able to selectively disable publish steps for all builds in the composed product was necessary. I did some work to allow disabling any given Pipebuild leg with the -d arg (e.g. “-d ""Regex:^Publish.*""”) but @dagood points out that there’s more to be done there since some repositories do things that need to be disabled in nearly every leg of their build. This issue tracks doing build definition refactoring work to factor functionality that needs to be optionally turned off out. There’s probably many ways to actually get this work done, but I’d suggest one of two: - Factor the optional behavior into independent pipelines (as defined by the pipelines.json for this repo) and disable them for servicing PIpebuild definitions as noted above - Establish Boolean properties that disable all undesirable behavior (publishing to feeds, etc) and set these properties in the -g section of the PipeBuild definition used. In both cases this work needs to be done in the repository using it, not in Pipebuild or other Engineering Services code. Simply disabling the publish leg in CoreFX helps, but it does mean we no longer get a VSTS Drop for each build and other tasks in the publish leg like symbol signing no longer run. It's not a huge deal to run a custom build later to do only the needed steps, but the team should decide what to do here.

"On Linux, we retrieve the speed of a network interface ""xyz"" by looking at the file `/sys/class/net/xyz/speed`. This file contains the connection speed in **megabits** per second, but `NetworkInterface.Speed` specifies that it returns a value in **bits** per second. This is a small change that converts between those two units. @stephentoub @pawelgerr Fixes https://github.com/dotnet/corefx/issues/21226" 21273 area-System.IO [NetFx/Mono compat] File.Delete throws IOException on non-existing file on a read-only file system on Linux "Repro steps: ```bash $ sudo mkdir -p /mnt/readonlyfs $ sudo mount --bind / /mnt/readonlyfs $ sudo mount -o remount,ro,bind / /mnt/readonlyfs $ cd /mnt/readonlyfs && touch test.txt # just to be sure touch: cannot touch ‘test.txt’: Read-only file system ``` ```bash $ cd ~ $ dotnet new console ... add the following code in Main(): ...

A good approximation of a starting point is looking at existing APIs that work with arrays or pointers (and to some extent strings), and determining which of these should have `Span`/`Buffer`-based overloads (there will almost certainly be “new” APIs we’ll want to add that don’t currently have overloads, but for the most part those can be dealt with separately and one-off). There are ~3000 such methods that exist today in the corefx reference assemblies. We’re obviously not going to add ~3000 new overloads that work with `Span`/`Buffer`, nor should we. But many of these aren’t relevant for one reason or another, e.g. they’re in components considered to be legacy, they’re very unlikely to be used on hot paths where a span/buffer->array conversion would matter at all, etc. I’ve gone through the framework and identified a relatively small set of methods I believe we should start with and add together for the next release. This is dialable, of course, but I believe we need a solid set of these to represent enough mass that span/buffer permeate the stack and make sense to use in an application. All of these are cases where using a span or a buffer instead of an array makes a quantifiable difference in allocation, and thus can have a measurable impact on the overall memory profile of a consuming application, contributing to an overall improvement in performance. #### System.BitConverter BitConverter is used to convert between primitive types and bytes, but the current APIs force an unfortunate amount of allocation due to working with byte[]s. We can help to avoid much of that by adding overloads that work with `Span`, adding `CopyBytes` methods instead of `GetBytes` methods, and adding `To*` overloads that accept `ReadOnlySpan` instead of accepting `byte[]`. ```C# namespace System { public static class BitConverter { // Matching overloads for GetBytes. Copy to the destination span // rather than allocating a new byte[]. Return false if the destination // span isn't large enough, which can be determined before any copying. public static bool TryWriteBytes(Span destination, bool value); public static bool TryWriteBytes(Span destination, char value); public static bool TryWriteBytes(Span destination, double value); public static bool TryWriteBytes(Span destination, short value); public static bool TryWriteBytes(Span destination, int value); public static bool TryWriteBytes(Span destination, long value); public static bool TryWriteBytes(Span destination, float value); public static bool TryWriteBytes(Span destination, ushort value); public static bool TryWriteBytes(Span destination, uint value); public static bool TryWriteBytes(Span destination, ulong value); // matching overloads for To* public static bool ToBoolean(ReadOnlySpan value); public static char ToChar(ReadOnlySpan value); public static double ToDouble(ReadOnlySpan value); public static short ToInt16(ReadOnlySpan value); public static int ToInt32(ReadOnlySpan value); public static long ToInt64(ReadOnlySpan value); public static float ToSingle(ReadOnlySpan value); public static ushort ToUInt16(ReadOnlySpan value); public static uint ToUInt32(ReadOnlySpan value); public static ulong ToUInt64(ReadOnlySpan value); … } } ``` EDIT 7/18/2017: Updated based on API review. Separated out into https://github.com/dotnet/corefx/issues/22355 for implementation. #### System.Convert As with BitConverter, the Convert class is also used to convert arrays. Most of the members are about converting from individual primitives to other individual primitives, but several work with arrays, in particular those for working with Base64 data. We should add the following methods: ```C# namespace System { public class Convert { public static string ToBase64String(ReadOnlySpan bytes, Base64FormattingOptions options = Base64FormattingOptions.None); public static bool TryToBase64Chars(ReadOnlySpan bytes, Span chars, out int bytesConsumed, out int charsWritten, Base64FormattingOptions options = Base64FormattingOptions.None); public static bool TryFromBase64String(string s, Span bytes, out int charsConsumed, out int bytesWritten); public static bool TryFromBase64Chars(ReadOnlySpan chars, Span bytes, out int charsConsumed, out int bytesWritten); … } } ``` Separated out as https://github.com/dotnet/corefx/issues/22417 for implementation. #### System.Random The Random class provides a NextBytes method that takes a byte[]. In many situations, that’s fine, but in some you’d like to be able to get an arbitrary amount of random data without having to allocate such an array, and we can do that with spans. For example, here’s a case where we’re getting some random data only to then want a Base64 string from it: https://referencesource.microsoft.com/#System/net/System/Net/WebSockets/WebSocketHelpers.cs,366 ```C# namespace System { public class Random { public virtual void NextBytes(Span buffer); … } } ``` Separated out into https://github.com/dotnet/corefx/issues/22356 for implementation. #### Primitive Parse methods Related to BitConverter and Convert, it’s very common to want to parse primitive values out of strings. Today, that unfortunately often involves creating substrings representing the exact piece of text, and then passing it to a string-based TryParse method. Similarly, it's common to convert primitives to strings via a method like ToString. Instead, I suggest we add the following: ```C# namespace System { public struct Int16 { public short Parse(ReadOnlySpan chars, NumberStyles style = NumberStyles.Integer, NumberFormatInfo info = null); public bool TryParse(ReadOnlySpan chars, out short result, NumberStyles style = NumberStyles.Integer, NumberFormatInfo info = null); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider provider = null); … } … // similar Parse/TryParse/TryFormat methods for each of: // Int32 // Int64 // UInt16 // UInt32 // UInt64 // Decimal // Double // Single // Boolean (no NumberStyle/NumberFormatInfo args) } ``` Separated out as https://github.com/dotnet/corefx/issues/22403 for implementation. Then we should also support parsing a few common types out of `ReadOnlySpan`: ```C# namespace System { public struct DateTime { public static DateTime Parse(ReadOnlySpan s, IFormatProvider provider = null, System.Globalization.DateTimeStyles styles = DateTimeStyles.None); public static DateTime ParseExact(ReadOnlySpan s, string format, IFormatProvider provider, DateTimeStyles style = DateTimeStyles.None); public static DateTime ParseExact(ReadOnlySpan s, string[] formats, IFormatProvider provider, DateTimeStyles style); public static bool TryParse(ReadOnlySpan s, out DateTime result, IFormatProvider provider = null, DateTimeStyles styles = DateTimeStyles.None); public static bool TryParseExact(ReadOnlySpan s, string format, IFormatProvider provider, DateTimeStyles style, out DateTime result); public static bool TryParseExact(ReadOnlySpan s, string[] formats, IFormatProvider provider, DateTimeStyles style, out DateTime result); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider provider = null); … } public struct DateTimeOffset { public static DateTimeOffset Parse(ReadOnlySpan input, IFormatProvider formatProvider = null, System.Globalization.DateTimeStyles styles = DateTimeStyles.None); public static DateTimeOffset ParseExact(ReadOnlySpan input, string format, IFormatProvider formatProvider, DateTimeStyles styles = DateTimeStyles.None); public static DateTimeOffset ParseExact(ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, DateTimeStyles styles); public static bool TryParse(ReadOnlySpan input, out DateTimeOffset result, IFormatProvider formatProvider = null, DateTimeStyles styles = DateTimeStyles.None); public static bool TryParseExact(ReadOnlySpan input, string format, IFormatProvider formatProvider, DateTimeStyles styles, out DateTimeOffset result); public static bool TryParseExact(ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, DateTimeStyles styles, out DateTimeOffset result); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider formatProvider = null); … } public struct TimeSpan { public static TimeSpan Parse(ReadOnlySpan input, IFormatProvider formatProvider = null); public static TimeSpan ParseExact (ReadOnlySpan input, string format, IFormatProvider formatProvider, TimeSpanStyles styles = TimeSpanStyles.None); public static TimeSpan ParseExact (ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, TimeSpanStyles styles = TimeSpanStyles.None); public static bool TryParse(ReadOnlySpan input, out TimeSpan result, IFormatProvider formatProvider = null); public static bool TryParseExact (ReadOnlySpan input, string format, IFormatProvider formatProvider, out TimeSpan result, TimeSpanStyles styles = TimeSpanStyles.None); public static bool TryParseExact (ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, out TimeSpan result, TimeSpanStyles styles = TimeSpanStyles.None); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider provider = null); … } public class Version { public static Version Parse(ReadOnlySpan input); public static bool TryParse(ReadOnlySpan input, out Version result); public bool TryFormat(Span destination, out int charsWritten, int fieldCount = 4); … } } ``` EDIT 7/18/2017: Updated per API review DateTime{Offset} separated out as https://github.com/dotnet/corefx/issues/22358 for implementation. TimeSpan separated out as https://github.com/dotnet/corefx/issues/22375 for implementation. Version separated out as https://github.com/dotnet/corefx/issues/22376 for implementation. #### System.Guid Guids are often constructed from byte[]s, and these byte[]s are often new’d up, filled in, and then provided to the Guid, e.g. https://referencesource.microsoft.com/#mscorlib/system/guid.cs,b622ef5f6b76c10a,references We can avoid such allocations with a Span ctor, with the call sites instead creating a Span from 16 bytes of stack memory. Guids are also frequently converted to byte[]s to be output, e.g. https://referencesource.microsoft.com/#mscorlib/system/guid.cs,94f5d8dabbf0dbcc,references and we can again avoid those temporary allocations by supporting copying the Guid’s data to a span: ```C# namespace System { public struct Guid { public Guid(ReadOnlySpan b); // correspond to Guid(byte[] b) public bool TryWriteBytes(Span destination); public static Guid Parse(ReadOnlySpan input); public static Guid ParseExact(ReadOnlySpan input, string format); public static bool TryParse(ReadOnlySpan input, out Guid result); public static bool TryParseExact(ReadOnlySpan input, string format, out Guid result); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider provider = null); … } } ``` EDIT 7/18/2017: Updated per API review Separated out as https://github.com/dotnet/corefx/issues/22377 for implementation. #### System.String It’ll be very common to create strings from spans. We should have a ctor for doing so: ```C# namespace System { public class String { public String(ReadOnlySpan value); … } } ``` Separated out as https://github.com/dotnet/corefx/issues/22378 for implementation. In addition to the new ctor on String, we should also expose an additional Create method (not a ctor so as to support a generic method argument). One of the difficulties today with String being immutable is it’s more expensive for developers to create Strings with custom logic, e.g. filling a char[] and then creating a String from that. To work around that expense, some developers have taken to mutating strings, which is very much frowned upon from a BCL perspective, e.g. by using the String(char, int) ctor to create the string object, then using unsafe code to mutate it, and then handing that back. We could handle such patterns by adding a method like this: ```C# namespace System { public delegate void StringCreateAction(TState state, Span destination); public class String { public static string Create(int length, TState state, StringCreateAction action); … } } ``` Separated out as https://github.com/dotnet/corefx/issues/22380 for implementation. The value of overloads like this is amplified when you start using them together. For example, here’s an example of creating a random string: https://referencesource.microsoft.com/#System.Web.Mobile/UI/MobileControls/Adapters/ChtmlTextBoxAdapter.cs,62 This incurs the allocation of a byte[] to pass to Random, a char[] as a temporary from which to create the string, and then creating the string from that char[]; unnecessary copies and allocations. Finally, we may also want to provide string.Format support for `ReadOnlyBuffer` as an argument; although passing it as an object will box it, string.Format could write it to the generated string without needing an intermediary string created, so a smaller allocation and avoiding an extra copy. #### System.IO.Stream ```C# namespace System.IO { public class Stream { public virtual int Read(Span destination); public virtual ValueTask ReadAsync(Buffer destination, CancellationToken cancellationToken = default(CancellationToken)); public virtual void Write(ReadOnlySpan source); public virtual Task WriteAsync(ReadOnlyBuffer source, CancellationToken cancellationToken = default(CancellationToken)); … } } ``` EDIT 7/18/2017: Updated per API review. Separated out as https://github.com/dotnet/corefx/issues/22381 for implementation. The base `{ReadOnly}Buffer`-accepting methods can use TryGetArray to access a wrapped array if there is one, then delegating to the existing array-based overloads. If the buffer doesn’t wrap an array, then it can get a temporary array from ArrayPool, delegate and copy (for reads) or copy and delegate (for writes). The base `Span`-accepting methods can do the ArrayPool/delegation approach in all cases. We’ll then need to override these methods on all relevant streams: FileStream, NetworkStream, SslStream, DeflateStream, CryptoStream, MemoryStream, UnmanagedMemoryStream, PipeStream, NullStream, etc. to provide more efficient `Span`/`Buffer`-based implementations, which they should all be able to do. In a few corner cases, there are streams where the synchronous methods are actually implemented as wrappers for the asynchronous ones; in such cases, we may be forced to live with the ArrayPool/copy solution. However, in such cases, the synchronous implementation is already relatively poor, incurring additional costs (e.g. allocations, blocking a thread, etc.), and they’re that way in part because synchronous usage of such streams is discouraged and thus these haven’t been very optimized, so the extra overhead in these cases is minimal. Once these additional methods exist, we’ll want to use them in a variety of places in implementation around corefx, e.g. https://github.com/dotnet/corefx/blob/d6b11250b5113664dd3701c25bdf9addfacae9cc/src/Common/src/System/Net/WebSockets/ManagedWebSocket.cs#L1140 as various pieces of code can benefit not only from the use of `Span`/`Buffer`, but also from the async methods returning `ValueTask` instead of `Task`, and the corresponding reduced allocations for ReadAsync calls that complete synchronously. #### System.IO.BufferStream and System.IO.ReadOnlyBufferStream Just as we have a MemoryStream that works with `byte[]` and an UnmanagedMemoryStream that works with a `byte*` and a length, we need to support treating `Buffer` and `ReadOnlyBuffer` as streams. It’s possible we could get away with reimplementing `MemoryStream` on top of `Buffer`, but more than likely this would introduce regressions for at least some existing use cases. Unless demonstrated otherwise, we will likely want to have two new stream types for these specific types: ```C# namespace System.IO { public class BufferStream : Stream { public BufferStream(Buffer buffer); public BufferStream(Buffer buffer, bool publiclyVisible); public bool TryGetBuffer(out Buffer buffer); … // overrides of all members on Stream } public class ReadOnlyBufferStream : Stream { public ReadOnlyBufferStream(ReadOnlyBuffer buffer); public ReadOnlyBufferStream(ReadOnlyBuffer buffer, bool publiclyVisible); public bool TryGetBuffer(out ReadOnlyBuffer buffer); … // overrides of all members on Stream, with those that write throwing NotSupportedException } } ``` The name of BufferStream is unfortunately close to that of BufferedStream, and they mean very different things, but I’m not sure that’s important enough to consider a less meaningful name. Separated out as https://github.com/dotnet/corefx/issues/22404 for discussion and implementation. Optional: It’s also unfortunate that all of these various memory-based streams don’t share a common base type or interface; we may want to add such a thing, e.g. an interface that anything which wraps a `Buffer` can implement… then for example code that uses Streams and has optimizations when working directly with the underlying data can query for the interface and special-case when the underlying `Buffer` can be accessed, e.g. ```C# namespace System { public interface IHasBuffer { bool TryGetBuffer(out Buffer buffer); bool TryGetBuffer(out ReadOnlyBuffer buffer); } } ``` We could implement this not only on `BufferStream` and `ReadOnlyBufferStream`, but also on `MemoryStream`, `UnmanagedMemoryStream`, and even on non-streams, basically anything that can hand out a representation of its internals as buffers. Separated out as https://github.com/dotnet/corefx/issues/22404 for discussion and implementation. #### System.IO.TextReader and System.IO.TextWriter As with streams, we should add the relevant base virtuals for working with spans/buffers: ```C# namespace System.IO { public class TextReader { public virtual int Read(Span span); public virtual ValueTask ReadAsync(Buffer buffer); public virtual int ReadBlock(Span span); public virtual ValueTask ReadBlockAsync(Buffer buffer); … } public class TextWriter { public virtual void Write(ReadOnlySpan span); public virtual Task WriteAsync(ReadOnlyBuffer buffer, CancellationToken cancellationToken = default(CancellationToken)); public virtual void WriteLine(ReadOnlySpan span); public virtual Task WriteLineAsync(ReadOnlyBuffer buffer, CancellationToken cancellationToken = default(CancellationToken)); … } } ``` We’ll then also need to override these appropriately on our derived types, e.g. StreamReader, StreamWriter, StringReader, etc. Separated out as https://github.com/dotnet/corefx/issues/22406 for implementation. #### System.IO.BinaryReader and System.IO.BinaryWriter As with TextReader/Writer, we also want to enable the existing BinaryReader/Writer to work with spans: ```C# namespace System.IO { public class BinaryReader { public virtual int Read(Span span); public virtual int Read(Span span); … } public class BinaryWriter { public virtual int Write(ReadOnlySpan span); public virtual void Write(ReadOnlySpan span); … } } ``` The base implementations of these can work with the corresponding new methods on Stream. Separated out as https://github.com/dotnet/corefx/issues/22428 and https://github.com/dotnet/corefx/issues/22429 for implementation. #### System.IO.File EDIT 6/26/2017: For now I've removed these File methods, as it's unclear to me at this point that they actually meet the core need. If you're repeatedly reading and pass a span that's too small, you're going to need to read again after handling the read data, but with these APIs as defined, each read results in needing to open and the close the file again; similarly if you're using the write APIs to write a file in pieces. At that point you're better off just using FileStream and reading/writing spans and buffers. We should look to add helpers here when we can figure out the right helpers at the right level of abstraction, e.g. should we expose the ability to just create a SafeFileHandle and then have these helpers operate on SafeFileHandle rather than on a string path? ~~The File class provides helpers for reading/writing data from/to files. Today the various “read/write data as bytes” functions work with byte[]s, which mean allocating potentially very large byte[]s to store the data to be written or that’s read. This can be made much more efficient with spans, allowing the buffers to be pooled (in particular for file reads).~~ ``` // Previously proposed. API decision: Won't add for now. namespace System.IO { public static class File { public static int ReadAllBytes(string path, long offset, Span span, out long remaining); public static ValueTask<(int bytesRead, long bytesRemaining)> ReadAllBytesAsync(string path, long offset, Buffer buffer); public static void WriteAllBytes(string path, ReadOnlySpan span); public static Task WriteAllBytesAsync(string path, ReadOnlyBuffer buffer); public static void AppendAllBytes(string path, ReadOnlySpan span); public static Task AppendAllBytesAsync(string path, ReadOnlyBuffer buffer); … } } ``` #### System.Text.StringBuilder StringBuilder is at the core of lots of manipulation of chars, and so it’s a natural place to want to work with `Span` and `ReadOnlySpan`. At a minimum we should add the following APIs to make it easy to get data in and out of a StringBuilder without unnecessary allocation: ```C# namespace System.Text { public class StringBuilder { public StringBuilder Append(ReadOnlySpan value); public StringBuilder Insert(int index, ReadOnlySpan value); public void CopyTo(int sourceIndex, Span destination, int count); … } } ``` Separated out as https://github.com/dotnet/corefx/issues/22430. In addition to these, we’ll also want to consider a mechanism for exposing the one or more buffers StringBuilder internally maintains, allowing them to be accessed as `ReadOnlySpan`. This is covered separately by #21248. #### System.Text.Encoding The Encoding class already exposes a lot of methods for converting between chars/strings and bytes, and it includes overloads for both arrays and pointers. While it might seem onerous to add an additional set for spans, the number of new overloads needed is actually fairly small, and we can provide reasonable default base implementations in terms of the existing pointer-based overloads. These methods could potentially have optimized derived overrides, but more generally they will help the platform to have a consistent feel, avoiding the need for devs with spans to use unsafe code to access the pointer-based methods. ```C# namespace System.Text { public class Encoding { public virtual int GetByteCount(ReadOnlySpan chars); public virtual bool TryGetBytes(ReadOnlySpan chars, Span bytes, out int charsConsumed, out int bytesWritten); public virtual int GetCharCount(ReadOnlySpan bytes); public virtual bool TryGetChars(ReadOnlySpan bytes, Span chars, out int bytesConsumed, out int charsWritten); public virtual string GetString(ReadOnlySpan bytes); public virtual ReadOnlySpan Preamble { get; } … } } ``` Separated out as https://github.com/dotnet/corefx/issues/22431. #### System.Numerics ```C# namespace System.Numerics { public struct BigInteger { public BigInteger(ReadOnlySpan value); public int GetByteCount(); public bool TryWriteBytes(Span destination, out int bytesWritten); public static BigInteger Parse(ReadOnlySpan value, NumberStyles style = NumberStyles.Integer, IFormatProvider provider = null); public static bool TryParse(ReadOnlySpan value, out BigInteger result, NumberStyles style = NumberStyles.Integer, IFormatProvider provider = null); … } } ``` Separated out in https://github.com/dotnet/corefx/issues/22401 for implementation. Even with BigInteger being a less-commonly-used type, there are still places even in our own code where this would be helpful: https://source.dot.net/#System.Security.Cryptography.X509Certificates/Common/System/Security/Cryptography/DerSequenceReader.cs,206 In fact, BigInteger’s implementation itself could benefit from this, such as with parsing: https://referencesource.microsoft.com/#System.Numerics/System/Numerics/BigNumber.cs,411 #### System.Net.IPAddress It’s very common to create IPAddresses from data gotten off the network, and in high-volume scenarios. Internally we try to avoid creating `byte[]`s to pass to IPAddress when constructing them, such as by using an internal pointer-based ctor, but outside code doesn’t have that luxury. We should make it possible to go to and from IPAddress without additional allocation: ```C# namespace System.Net { public class IPAddress { public IPAddress(ReadOnlySpan address); public IPAddress(ReadOnlySpan address, long scopeid); public bool TryWriteBytes(Span destination, out int bytesWritten); public static IPAddress Parse(ReadOnlySpan ipChars); public static bool TryParse(ReadOnlySpan ipChars, out IPAddress address); public static bool TryFormat(Span destination, out int charsWritten); … } } ``` Even internally this will be useful in cases like these: https://source.dot.net/#System.Net.NetworkInformation/Common/System/Net/SocketAddress.cs,135 https://source.dot.net/#System.Net.NameResolution/Common/System/Net/Internals/IPAddressExtensions.cs,21 EDIT 7/25/2017: Updated based on API review Separated out as https://github.com/dotnet/corefx/issues/22607 for implementation. #### System.Net.Sockets This is one of the more impactful areas for spans and buffers, and having these methods will be a welcome addition to the Socket family. Today, there are lots of existing methods on sockets, e.g. an overload for sync vs async with the APM pattern vs async with Task vs async with SocketAsyncEventArgs, and overload for Send vs Receive vs SendTo vs ReceiveMessageFrom vs… etc. I do not think we should add an entire new set of span/buffer-based methods, and instead we should start with the most impactful. To me, that means adding the following two synchronous and two Task-based asynchronous overloads for sending and receiving: ```C# namespace System.Net.Sockets { public class Socket { public int Receive(Span buffer, SocketFlags flags); public int Receive(Span buffer, SocketFlags socketFlags, out SocketError errorCode); public int Send(ReadOnlySpan buffer, SocketFlags flags); public int Send(ReadOnlySpan buffer, SocketFlags flags, out SocketError errorCode); … } public class SocketTaskExtensions { public static ValueTask ReceiveAsync(this Socket socket, Buffer buffer, SocketFlags socketFlags, CancellationToken cancellationToken = default(CancellationToken)); public static ValueTask SendAsync(this Socket socket, ReadOnlyBuffer buffer, SocketFlags socketFlags, CancellationToken cancellationToken = default(CancellationToken)); … } } ``` Note that I’ve put the ReceiveAsync and SendAsync overloads on the SocketTaskExtensions class as that’s where the existing overloads live. We could choose to instead make these new overloads instance methods on Socket. In addition, the highest-performing set of APIs with sockets are based on SocketAsyncEventArgs. To support those, we should add the following: ```C# namespace System.Net.Sockets { public class SocketAsyncEventArgs { public void SetBuffer(Buffer buffer); public Buffer GetBuffer(); … } } ``` The implementation currently stores a `byte[]` buffer. We can change that to store a `Buffer` instead, and just have the existing `SetBuffer(byte[])` overload wrap the `byte[]` in a `Buffer`. There is an existing `Buffer { get; }` property as well. We can change that to just use TryGetArray on the internal buffer and return it if it exists, or else null. The `GetBuffer` method is then there to support getting the set `Buffer`, in case the supplied buffer wrapped something other than an array. EDIT 7/25/2017: Updated based on API review Separated out as https://github.com/dotnet/corefx/issues/22608 for implementation #### System.Net.WebSockets.WebSocket Similar to Socket is WebSocket, in that it’s desirable to be able to use these APIs with finer-grain control over allocations than is currently easy or possible, and in high-throughput situations. We should add the following members: ```C# namespace System.Net.WebSockets { public class WebSocket { public virtual ValueTask ReceiveAsync(Buffer buffer, CancellationToken cancellationToken = default(CancellationToken)); public virtual Task SendAsync(ReadOnlyBuffer buffer, CancellationToken cancellationToken = default(CancellationToken)); … } } ``` Note that ReceiveAsync is returning a ValueTask rather than a Task (to avoid that allocation in the case where the operation can complete synchronously), and it’s wrapping a ValueWebSocketReceiveResult instead of a WebSocketReceiveResult. The latter is the type that currently exists, but is a class. I’m suggesting we also add the following struct-based version, so that receives can be made to be entirely allocation-free in the case of synchronous completion, and significantly less allocating even for async completion. ```C# namespace System.Net.WebSockets { public struct ValueWebSocketReceiveResult { public ValueWebSocketReceiveResult(int count, WebSocketMessageType messageType, bool endOfMessage); public ValueWebSocketReceiveResult(int count, WebSocketMessageType messageType, bool endOfMessage, WebSocketCloseStatus? closeStatus, string closeStatusDescription); public WebSocketCloseStatus? CloseStatus { get; } public string CloseStatusDescription { get; } public int Count { get; } public bool EndOfMessage { get; } public WebSocketMessageType MessageType { get; } } } ``` EDIT 7/25/2017: Updated per API review Separated out as https://github.com/dotnet/corefx/issues/22610 for implementation #### System.Net.Http This area still needs more thought. My current thinking is at a minimum we add the following: ```C# namespace System.Net.Http { public class HttpClient { public ValueTask GetBytesAsync(Uri requestUri, Buffer buffer); … } public sealed class ReadOnlyBufferContent : HttpContent { public ReadOnlyBufferContent(ReadOnlyBuffer buffer); … // override relevant members of HttpContent } } ``` The GetBytesAsync overload avoids the need for allocating a potentially large byte[] to store the result, and the ReadOnlyBufferContent makes it easy to upload `ReadOnlyBuffer`s rather than just `byte[]`s. There is potentially more that can be done here, but I suggest we hold off on that until we investigate more deeply to understand what we’d need to plumb throughout the system. HttpClient is itself a relatively small wrapper on top of HttpClientHandler, of which there are multiple implementations (ours and others’), and to plumb a buffer all the way down through would involve new APIs and implementation in HttpClientHandler implementations. Definitely something to investigate. Separated out as https://github.com/dotnet/corefx/issues/22612 for implementation (ReadOnlyBufferContent... we decided against the GetBytesAsync helper for now in 7/25/2017 API review) #### System.Security.Cryptography namespace Several hashing-related types in System.Security.Cryptography would benefit from being able to work with data without allocating potentially large `byte[]`s. One is HashAlgorithm, which has several methods for processing an input `byte[]` and allocating/filling an output `byte[]`: ```C# namespace System.Security.Cryptography { public abstract class HashAlgorithm { public bool TryComputeHash(ReadOnlySpan source, Span destination, out int bytesWritten); protected virtual void HashCore(ReadOnlySpan source); protected virtual bool TryHashFinal(Span destination, out int bytesWritten); … } } ``` EDIT 7/25/2017: Updated per API review Separated out as https://github.com/dotnet/corefx/issues/22613 for implementation Similarly, several overloads would be beneficial on IncrementalHash: ```C# namespace System.Security.Cryptography { public sealed class IncrementalHash { public void AppendData(ReadOnlySpan data); public bool TryGetHashAndReset(Span destination, out int bytesWritten); … } } ``` EDIT 7/25/2017: Updated per API review Separated out as https://github.com/dotnet/corefx/issues/22614 for implementation Similarly, several encryption/signing related types would benefit from avoiding such `byte[]` allocations: ```C# namespace System.Security.Cryptography { public abstract class RSA : AsymmetricAlgorithm { public virtual bool TryDecrypt(ReadOnlySpan source, Span destination, RSAEncryptionPadding padding, out int bytesWritten); public virtual bool TryEncrypt(ReadOnlySpan source, Span destination, RSAEncryptionPadding padding, out int bytesWritten); protected virtual bool TryHashData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, out int bytesWritten); public virtual bool TrySignData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, RSASignaturePadding padding, out int bytesWritten); public virtual bool TrySignHash(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, RSASignaturePadding padding, out int bytesWritten); public virtual bool VerifyData(ReadOnlySpan data, ReadOnlySpan signature, HashAlgorithmName hashAlgorithm, RSASignaturePadding padding); public virtual bool VerifyHash(ReadOnlySpan hash, ReadOnlySpan signature, HashAlgorithmName hashAlgorithm, RSASignaturePadding padding); … } public abstract class DSA : AsymmetricAlgorithm { public virtual bool TryCreateSignature(ReadOnlySpan source, Span destination, out int bytesWritten); protected virtual bool TryHashData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, out int bytesWritten); public virtual bool TrySignData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, out int bytesWritten); public virtual bool VerifyData(ReadOnlySpan data, ReadOnlySpan signature, HashAlgorithmName hashAlgorithm); public virtual bool VerifySignature(ReadOnlySpan rgbHash, ReadOnlySpan rgbSignature); … } public abstract class ECDsa : AsymmetricAlgorithm { protected virtual bool TryHashData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, out int bytesWritten); public virtual bool TrySignData(ReadOnlySpan source, Span destination, HashAlgorithmName hashAlgorithm, out int bytesWritten); public virtual bool TrySignHash(ReadOnlySpan source, Span destination, out int bytesWritten); public virtual bool VerifyData(ReadOnlySpan data, ReadOnlySpan signature, HashAlgorithmName hashAlgorithm); public virtual bool VerifyHash(ReadOnlySpan hash, ReadOnlySpan signature); … } } ``` EDIT 7/25/2017: Update per API review Separated out of https://github.com/dotnet/corefx/issues/22615 for implementation One other place where we’d want to be able to use span is `ICryptoTransform`. Lots of APIs, mainly CreateEncryptor and CreateDecryptor, methods return ICryptoTransform, and it has one it a TransformBlock and TransformFinalBlock method that works with `byte[]`. We’d really like support in terms of `ReadOnlySpan` and `Span`. I see four options here: 1. Do nothing. 2. Add a second `ISpanCryptoTransform` interface, and a second set of differently-named CreateEncryptor/Decryptor methods for creating instances of these. 3. Add a second `ISpanCryptoTransform` interface that’s also implemented by our implementations, and have consuming code query for the interface and use it if it exists. 4. If we get support for default interface methods (https://github.com/dotnet/csharplang/issues/52), add these span-based overloads to the interface, with a default implementation in terms of the existing methods. My strong preference is for (4), but that’s based on a feature that doesn’t yet exist. As such, my suggestion is to hold off on this until it’s clear whether such a feature will exist: if it will, do (4) once it does, otherwise do (3). EDIT 7/25/2017: Decision: 4 if/when the feature exists, and 1 until then. #### Other namespaces There are some other namespaces that could likely benefit from Span/Buffer, but we should probably handle separately from this initial push: - System.Collections. It’s not clear to me to what extent we should add span/buffer-based APIs to collections. CopyTo overloads that take `Span`? Callback-based methods for exposing the internal storage via a `ReadOnlySpan` (if that makes sense for the relevant collection)? This needs more thought. - System.Collections.Immutable. Just as `T[]` has an implicit operator to a `Span`, we should consider adding an `ImmutableArray` operator for converting to a `ReadOnlySpan`. - System.Reflection.Metadata. It’s very specialized, and I’ve not included it in this issue. It can be handled separately. ### Known Open Issues There are several cross-cutting open issues that apply to many of these APIs: - How to handle cases where data is too large for the supplied span/buffer provided? Throw? Simply return a “not big enough” indication? Return how much data was written along with such an indication? Return how much data was written and attempt to return how much more space is needed if possible? Etc. Related to that, do we want to enable an approach where you can call the method with an empty output span and get back an upper bound for the maximum amount of space that will be needed, such that you can then call it again with a sufficient buffer? - Argument names. For overloads, should we generally name arguments “span” for `ReadOnlySpan` and `Span`, and “buffer” for `ReadOnlyBuffer` and `Buffer`? What if the existing overload uses a different name, like “input” or “b”? What about cases where currently there’s a single argument (e.g. “input”) and then returns an array, and the new overload will have two span args, one input and one output? ## Next Steps 1. Discussion of this “minimal” proposal. My goal is to quickly arrive at a minimal set; there may be additional APIs we want beyond these, but are there any here we shouldn’t have? Are there any absolutely critical ones missing? 2. API review. I want to review all of these en-mass to ensure we’re being consistent across all of these members. 3. Once the APIs are approved, open individual issues for each set that’ll be worked on by an individual together. 4. Implement them, test them, and expose them. 21282 area-System.Security WindowsIdentity.IsAuthenticated is false when running in an AppContainer Tracking special-casing UWP in NegotiateStream_StreamToStream_Authentication_Success and NegotiateStream_StreamToStream_Authentication_TargetName_Success.

When such an event is encountered, the system fonts and colors are refreshed and re-cached, so that they stay up-to-date with the rest of the OS. On .NET Framework, these events are tracked through the `SystemEvents` class, located in System.dll. We don't have this functionality in .NET Core, but can consider adding it, perhaps directly in System.Drawing.Common.dll for now. All code using this is behind the `FEATURE_SYSTEM_EVENTS` flag. Note that this will probably only ever work on Windows, and not other operating systems. Another option is to simply delete the code, and document this as a minor quirk of the .NET Core version of the library. This would mean that, in very rare (incredibly rare?) circumstances, the colors and fonts returned by System.Drawing.Common would be out of sync with the rest of the system. @stephentoub @hughbe 21320 area-System.Net Unable to make https request when Oid lookup takes too long "This issue was discovered in .NET 4.6, but would also affect .NET core apps running on windows. Here is a link to the feedback I created on the connect website for this issue: https://connect.microsoft.com/VisualStudio/feedback/details/3136313 The solution is to use a different Oid constructor that prevents the potentially costly Oid friendly name lookup. What follows is a more detailed description of how issue we were seeing in our application. I support a desktop application that calls a WCF service hosted on our servers over https. A small number of our clients with the desktop application installed (~20/10000) have been reporting issues connecting to the WCF service since installing KB4014511. The exception being thrown is: System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host The error is misleading though. After quite a lot of troubleshooting, we were able to pinpoint the source of the problem. By decompiling the System.dll, I saw that the following 2 lines were added to the System.Net.Security.SecureChannel class shipped with KB4014511: private readonly Oid m_ServerAuthOid = new Oid(""1.3.6.1.5.5.7.3.1""); private readonly Oid m_ClientAuthOid = new Oid(""1.3.6.1.5.5.7.3.2""); The initialization of those Oid objects is triggering a system call to the CryptFindOIDInfo function to lookup the friendly name associated with the specified OID. When the machine is part of a domain, that call will perform the lookup against active directory (see the Remarks in the docs https://msdn.microsoft.com/en-us/library/windows/desktop/aa379938%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396). For our clients that are having issues connecting to our WCF service, this lookup is taking up to 15 seconds. Because these Oid lookups are happening after WCF has opened the TCP connection to our server, but before the SSL/TLS handshake has started, we are seeing the above error. So, the TCP connection is opened, 2 OID lookups happen taking up to 30 seconds, the application then attempts to start the SSL/TLS handshake, but by the time the SSL/TLS handshake is attempted, the TCP connection has already been reset by the server (in our case the server resets the connection after 10 seconds)." 21321 area-Infrastructure Enabling Multifile ILC Tests for uapaot-Release-x64 configuration cc: @danmosemsft @joshfree @tijoytom @botaberg @yizhang82 This will switch the Release-x64 configuration tests to run on multi-file mode instead of single-file. 21322 area-System.Collections Allow Json.NET deserialization of ObservableCollection Json.NET serializes the collection by enumerating it, without taking into account any of its fields like the binary serializer does, and deserializes it by adding the items back to the collection, without initializing the fields. However, it does still call the `OnSerializing`/`OnSerialized`/`OnDeserializing`/`OnDeserialized` methods. When it calls `OnDeserialized`, a NullRef exception is thrown when we try to access the `_monitor` field because the field has not been initialized, unlike with binary deserialization, where the field would have been initialized from the serialized binary data. A workaround is to simply check `if (_monitor != null)` before accessing it in `OnDeserialized`.

They will still be used for the mono configuration, because it supports these serialization features. * For classes and structs, I have moved the attribute declarations and, when applicable, the interface implementations into a *.Serializable.cs file. * For enums, I have removed the attribute entirely, as it was a no-op. * None of the new *.Serializable.cs files are included in the .NET Core build configuration. * All of the attributes and interfaces have been removed from the .NET Core reference assembly. @stephentoub @akoeplinger I chatted with both of you today about this. In the past, we have simply been deleting this code from corefx, since it's not used in the .NET Core implementation. However, we want to continue sharing these files with mono, and Alex mentioned this way was preferred. Mono already consumes a few of these files, so deleting the attributes outright would break some functionality. I'm open to tweaking this and using a different pattern if we find something that is easier to maintain. 21334 area-System.Security Fix temp keychain lifetime with macOS CopyWithPrivateKey Because macOS is the only platform that doesn't allow ephemeral keys to be associated with certificates we have a straightforward-yet-complex temporary keychain management system. In the new CopyWithPrivateKey methods, we end up messing with the refcounts and deleting too early because the input certificate got mutated by the call -- it believes it belongs to the keychain, even though it was subsequently removed from it. So when that cert handle disposes we DangerousRelease our shared lifetime handle even though we never did a DangerousAddRef. Since the new method is supposed to have no lasting side effects, and we've found one, change to use the Windows PAL approach: first clone the cert to disassociate it from mutation operations. The existing tests noticed this problem, which got the incorrect fix of a persisted field for the private key. But since PFX exporting is done within the keychain itself, if the keychain was deleted PFX export isn't possible. With the addition of PFX export tests from CopyWithPrivateKey we now have better ways of tracking that the keychain isn't deleted too early.

On .NET Framework, System.Net.Http is built on WebRequest (HttpWebRequest) and is subject to side-affects from it. The static property WebRequest.DefaultWebProxy affects the initial value of WebRequest.Proxy. So, it's possible that a developer may have set WebRequest.DefaultWebProxy to null prior to using System.Net.Http in the app. The net affect of this is that there won't be any proxy used as the system default proxy and thus the HttpClientHandler.DefaultProxyCredentials is ignored. On .NET Core, there is no relationship between System.Net.Http and System.Net.WebRequest. So, in all cases on .NET Core, where a developer has specified HttpClientHander.UseProxy=true and HttpClientHandler.Proxy = null (default values), the handler will always try to use the system default proxy (if configured). 21376 area-System.Runtime Fix failing System.Runtime.Interop.Tests on ILC "Fixes https://github.com/dotnet/corefx/issues/21348 Override all the remaining Reflection apis whose default implementation is ""throw"".

It would be tempting to just change the implementation to use `ArrayPool.Shared.Rent` to get that array, but this is problematic for a few reasons, mostly to do with existing code: 1. It's fairly common to not dispose MemoryStreams, as currently the Dispose is effectively a nop. But with wrapping buffers from `ArrayPool`, it's important to release the currently used buffer back to the pool when the stream is disposed. And it would be expensive to make MemoryStream finalizable to deal with this. 2. MemoryStream by default allows the buffers it creates to be exposed through its TryGetBuffer method. That means folks today could be taking and using these buffers, potentially even after the MemoryStream is disposed, which could lead to code using the array after the array is returned to the pool and potentially used by someone else. One solution would just be to introduce a new Stream type, e.g. ```C# namespace System.IO { public sealed class ArrayPoolStream : Stream { public ArrayPoolStream() : this(ArrayPool.Shared) { } public ArrayPoolStream(ArrayPool pool); ~ArrayPoolStream(); public ArraySegment DangerousGetArray(); ... // override all the relevant members on Stream } } ``` That has its own downsides, though. In particular, there's something nice about this just being a part of MemoryStream, being easily used in existing code that uses MemoryStreams, etc. Another option would be to just plumb this into MemoryStream, but in an opt-in manner, and accept some of the resulting limitations because they're opt-in: - Add a ctor: `public MemoryStream(ArrayPool pool)`. - When that ctor is used, buffers come from the pool rather than being new'd up. - If you don't Dispose, you leak the buffer, but since this only happens when you use the new ctor, we're at least not impacting existing code, and it's little different than just using the pool directly and not returning a buffer. - We either make TryGetBuffer return false, or as with Dispose we accept that you had to opt-in to this by using the new ctor. I'm leaning towards the second option: just add the new `MemoryStream(ArrayPool)` ctor, and allow TryGetBuffer to work; devs just need to know that when they create the stream with this ctor, they should dispose the stream, and they shouldn't use the array retrieved from TryGetBuffer after doing something else to the stream. 21381 area-System.Runtime Fix RuntimeInformation.FrameworkName for Uap and UapAot @sepidehMS found this while investigating System.ObjectModel.Tests which is caused by this.

This makes it impossible to establish connections with WSS endpoints that require mutual TLS authentication, which is blocking WCF scenarios in UWP. I'll be sending out a PR in the near future with a ""repro test"" (disabled for UAP) and will be working on fixing this shortcoming.

But for such APIs to be truly useful, and for `ReadOnlySpan` to be generally helpful as a string-like type, we need a set of extension methods on `ReadOnlySpan` that mirror the corresponding operations on string, e.g. Equals with various kinds of string comparisons, Trim, Replace, etc. We need to define, implement, test, and ship a core set of these (more can of course be added in the future), e.g. **Edit by @ahsonkhan - Updated APIs:** ```C# // All these do ordinal comparisons, and hence do not rely on StringComparison, and can live in System.Memory.dll public static class MemoryExtensions { // If we decide to add overloads to Trim in the future that are non-ordinal and take StringComparison // (similar to https://github.com/dotnet/corefx/issues/1244), they will be .NET Core specific. public static ReadOnlySpan Trim(this ReadOnlySpan span); public static ReadOnlySpan Trim(this ReadOnlySpan span, char trimChar); public static ReadOnlySpan Trim(this ReadOnlySpan span, ReadOnlySpan trimChars); public static ReadOnlySpan TrimStart(this ReadOnlySpan span); public static ReadOnlySpan TrimStart(this ReadOnlySpan span, char trimChar); public static ReadOnlySpan TrimStart(this ReadOnlySpan span, ReadOnlySpan trimChars); public static ReadOnlySpan TrimEnd(this ReadOnlySpan span); public static ReadOnlySpan TrimEnd(this ReadOnlySpan span, char trimChar); public static ReadOnlySpan TrimEnd(this ReadOnlySpan span, ReadOnlySpan trimChars); public static bool IsWhiteSpace(this ReadOnlySpan span); public static bool Remove(this ReadOnlySpan source, int startIndex, int count, Span destination); // Does exactly what string does today, i.e. ordinal, case-sensitive, culture-insensitive comparison public static bool Replace(this ReadOnlySpan source, ReadOnlySpan oldValue, ReadOnlySpan newValue, Span destination, out int bytesWritten); // To me, these are complementary to the Trim APIs and hence we should add them. public static bool PadLeft(this ReadOnlySpan source, int totalWidth, Span destination); public static bool PadLeft(this ReadOnlySpan source, int totalWidth, Span destination, char paddingChar); public static bool PadRight(this ReadOnlySpan source, int totalWidth, Span destination); public static bool PadRight(this ReadOnlySpan source, int totalWidth, Span destination, char paddingChar); } // Live in CoreLib and only available on .NET Core, exposed from System.Memory.dll // Atm, this class in corelib is called 'Span' and contains the .NET Core specific implementation of the extension methods public static class MemoryExtensions { public static bool Equals(this ReadOnlySpan span, ReadOnlySpan value, StringComparison comparison); public static int Compare(this ReadOnlySpan span, ReadOnlySpan value, StringComparison comparison); public static bool Contains(this ReadOnlySpan span, ReadOnlySpan value, StringComparison comparison); public static bool StartsWith(this ReadOnlySpan span, ReadOnlySpan value, StringComparison comparison); public static bool EndsWith(this ReadOnlySpan span, ReadOnlySpan value, StringComparison comparison); public static bool Replace(this ReadOnlySpan source, ReadOnlySpan oldValue, ReadOnlySpan newValue, StringComparison comparison, Span destination, out int bytesWritten); public static bool ToUpper(this ReadOnlySpan source, Span destination); public static bool ToUpper(this ReadOnlySpan source, Span destination, CultureInfo culture); public static bool ToUpperInvariant(this ReadOnlySpan source, Span destination); public static bool ToLower(this ReadOnlySpan source, Span destination); public static bool ToLower(this ReadOnlySpan source, Span destination, CultureInfo culture); public static bool ToLowerInvariant(this ReadOnlySpan source, Span destination); } ```

This is because on UAP, HttpClientHandler is built on the WinRT APIs which in turn are built on WinInet. And WinInet always uses authentication caching internally and this results in the net effect of PreAuthenticate always being ""true"". The default for .NET Framework and .NET Core (non-UAP) is ""false"". When this property was first added to .NET Core 1.1, the UAP version defaulted to true and the setter would throw PNSE. As part of .NET Core 2.0, API surface for networking APIs was expanded. This resulted in HttpWebRequest exposing and implementing a ""PreAuthenticate"" property, which is what it has historically done in .NET Framework. On .NET Core, HttpWebRequest is built on top of HttpClient. And so, HttpWebRequest was enhanced in .NET Core 2.0 to set the default of PreAuthenticate to false. But this later caused the PNSE exception to surface and this exception was caught in UWP app-compat testing. Essentially, we had now created the default HttpWebRequest to always throw an exception. So, in PR #18105, the PNSE in HttpClientHandler.PreAuthenticate was commented out and thus the setter became a no-op. This PR basically acknowledges this situation and removes the TODO from this change. Since there is no good way to implement the actual HttpClientHandler.PreAuthenticate property, I left the getter default to return ""true"" which is closer to reality of what happens on UAP (even though this default value is different from .NET Framework or the rest of .NET Core). And, in terms of the setter for the property, I opted to leave it as a no-op. This seems like the best compromise outcome for now and will generate less distraction for developers rather than throwing an exception all the time. The rest of this PR moves the ActiveIssue's from the class level to the method level as part of eventually solving all of them. In addition, I added a new test case to validate the HttpClientHandler constructor defaults that are different on the UAP platform.

In reality, size of IPv4 header can vary from 20 bytes to 60 bytes. Therefore `SendIcmpEchoRequestOverRawSocket()` works incorrectly when IPv4 header is larger than 20 bytes and fails to find a correct echoed packet due to wrong interpretation of a received packet. This failure is observed when running `System.Net.Ping.Functional.Tests.dll` on environment where IPv4 header is larger than 20 bytes and 12 tests are failed as below. ``` ``` I'm not expert in network implementation and looking forward any advice and comments on this issue. " 21460 area-System.Security [release/2.0] Fix temp keychain lifetime with macOS CopyWithPrivateKey Because macOS is the only platform that doesn't allow ephemeral keys to be associated with certificates we have a straightforward-yet-complex temporary keychain management system. In the new CopyWithPrivateKey methods, we end up messing with the refcounts and deleting too early because the input certificate got mutated by the call -- it believes it belongs to the keychain, even though it was subsequently removed from it. So when that cert handle disposes we DangerousRelease our shared lifetime handle even though we never did a DangerousAddRef. Since the new method is supposed to have no lasting side effects, and we've found one, change to use the Windows PAL approach: first clone the cert to disassociate it from mutation operations. The existing tests noticed this problem, which got the incorrect fix of a persisted field for the private key. But since PFX exporting is done within the keychain itself, if the keychain was deleted PFX export isn't possible. With the addition of PFX export tests from CopyWithPrivateKey we now have better ways of tracking that the keychain isn't deleted too early.

Instead of forcing people to write a dummy `Stream` implementation that handles incoming data on `WriteAsync`, a callback could be provided to get the data that `Stream` has to hand out.

The issue we are seeing is the app (acting as the webserver) stops responding because there are 500 worker threads accumulated over time that are hanging, which reached the threadpool limit for the process. We noticed that the hanging threads all have an identical stack, which shows that WinRtToNetFxStreamAdapter.Flush is calling the WinRTStream's flushASync and waiting forever for it. However on the WinRT side, the FlushAsync seems to be completing if called outside of the .NET context. We further noticed that this only repros with Debug build of the app, either using F5 debug or a standalone debug build without the debugger attached. On release builds, the issue does not repro. I have the repro app. Please email me when needed and I'll send you the zip. 21482 area-System.Net Escape '\' on Unix file uris to '%5C' for canonical form. On Unix it is valid for filenames to have char '\\'. According to URI RFC, on the wire, the backslash needs to be in percent-encoded form as %5C. Hence we are converting all '\\' and '%5C' in unix file uris to be '%5C' in Uri.AbsolutePath and Uri.AbsoluteUri. These return the canonical URI values. Also note, the Uri.LocalPath will return these unescaped as before.

DataSet and DataTable produced different blobs on Unix machines as their serialized payload contains line breaks: \r\n vs \n. 2. CookieContainer sets the machines domain to a field. Overwrote with reflection. 3. CompareInfo sets a SortVersion which is Windows OS machine dependent. Overwrote with reflection. 4. CookieCollection didn't contain a serializable field (m_version) probably because it was wrapped in pragmas and had its default value but only in CI, locally it was in the payload. The serialized value was also not 100% correct as the value should be the amount of cookies and not the default value of int. This isn't a breaking change as netfx doesn't use the value anymore for any operations. But with the change it's now always in the serialization payload. 21509 area-System.Net ManagedWebSocket needs resource strings Everything has TODO: ``` System.Net.WebSockets.WebSocketException (0x80004005): TODO, RESX: net_WebSockets_InvalidState; (CloseSent,Open, CloseReceived) at System.Net.WebSockets.WebSocketValidate.ThrowIfInvalidState(WebSocketState currentState, Boolean isDisposed, WebSocketState[] validStates) at System.Net.WebSockets.ManagedWebSocket.SendAsync(ArraySegment`1 buffer, WebSocketMessageType messageType, Boolean endOfMessage, CancellationToken cancellationToken) ``` 21510 area-System.Net HttpClientHandler.UseDefaultCredentials default value different on UAP "HttpClientHandler.UseDefaultCredentials should default to FALSE. On UAP, it is currently returning TRUE. Using default credentials on UAP also requires EnterpriseAuthentication capability on the UWP App, which is a capability that only certain approved Windows Store app developers can put onto their app. Usually this is allowed for developers with corporate Windows Store developer accounts (instead of individual). So, the flag 'UseDefaultCredentials' isn't really the only thing controlling whether default credentials actually gets sent. Also, regardless, default credentials are only sent along to endpoints that are considered ""intranet"". This is controlled automatically by the WinRT Windows.Web.Http APIs via the native Windows WinInet HTTP stack. For consistency with the other platforms, this #property should return FALSE by default. However, we already shipped the default of TRUE in prior UAP packages, so we should consider whether we should change this." 21511 area-System.Net Fix some HttpClientHandler properties for UAP Due to platform differences on UAP and the current use of WinRT APIs to implement that HTTP stack, a few properties won't have the same defaults or behavior.

However it gets copied only once to the test folder. So eg. if I run UAP tests for console, using /p:targetgroup=uap, I get the UAP one in my test folder: C:\git\corefx\bin\Windows_NT.AnyCPU.Debug\System.Console.Tests\netstandard\CoreFx.Private.TestUtilities.dll then if I try to run tests again, without /p:targetgroup=uap, the tests fail because it's trying to use the UAP copy of it. This binary comes from the test package (xunit.runtime.depproj) and I'm unsure how to modify that to fix it. @tarekgh / @weshaggard ? 21518 area-System.Console Fix occasional 'The data area passed to a system call is too small.' When running Console tests on one of my machines I sometimes get this error when it tries to get a console title of >1000 characters. GetConsoleTitle, is supposed to return the length of the buffer it wants, but sometimes instead it returns 0 and ERROR_INSUFFICIENT_BUFFER. I don't know why: I found mention on the web of this also. To fix this, in such a case, progressively try larger buffers until we hit our limit or it works. This makes the test pass on my laptop. Also I added +1 when we pass in the length of the StringBuilder. @JeremyKuhne pointed out (also documented [here](https://docs.microsoft.com/en-us/dotnet/framework/interop/default-marshaling-for-strings)) that .Capacity does not include the trailing null that the marshaler includes in the buffer it passes to the native call. 21520 area-Infrastructure AttributeError: DumplingConfig instance has no attribute 'dbgpath' "https://mc.dot.net/#/user/hughbe/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/a808e4f4bb61ed8002200c969d132a54769b2328/workItem/System.Runtime.InteropServices.Tests/wilogs ``` 2017-06-25 06:28:18,063: INFO: proc(54): run_and_log_output: Output: /home/helixbot/dotnetbuild/work/dd100005-e671-46fb-892b-4e743335ba82/Work/10f58f6f-862f-44af-9628-ca1652b6bf2e/Unzip/RunTests.sh: line 87: 2365 Segmentation fault (core dumped) $RUNTIME_PATH/dotnet xunit.console.netcore.exe System.Runtime.InteropServices.Tests.dll -xml testResults.xml -notrait Benchmark=true -notrait category=nonnetcoreapptests -notrait category=nonlinuxtests -notrait category=OuterLoop -notrait category=failing 2017-06-25 06:28:47,204: INFO: proc(54): run_and_log_output: Output: processing dump file /home/helixbot/dotnetbuild/work/dd100005-e671-46fb-892b-4e743335ba82/Work/10f58f6f-862f-44af-9628-ca1652b6bf2e/Unzip/core 2017-06-25 06:28:47,204: INFO: proc(54): run_and_log_output: Output: creating dumpling dump cf4c07f3f46a55e83f477e7c7164bcf510fa4343 2017-06-25 06:28:47,204: INFO: proc(54): run_and_log_output: Output: uploading artifact cf4c07f3f46a55e83f477e7c7164bcf510fa4343 core 2017-06-25 06:28:47,204: INFO: proc(54): run_and_log_output: Output: Traceback (most recent call last): 2017-06-25 06:28:47,204: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 1128, in 2017-06-25 06:28:47,205: INFO: proc(54): run_and_log_output: Output: main(sys.argv) 2017-06-25 06:28:47,205: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 1123, in main 2017-06-25 06:28:47,205: INFO: proc(54): run_and_log_output: Output: cmdProc.Process(config) 2017-06-25 06:28:47,205: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 529, in Process 2017-06-25 06:28:47,205: INFO: proc(54): run_and_log_output: Output: self.Upload(config) 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 624, in Upload 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: self.UploadDump(config) 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 644, in UploadDump 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: self._triage_dump(dumpid, config.dumppath, config) 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: File ""/home/helixbot/.dumpling/dumpling.py"", line 812, in _triage_dump 2017-06-25 06:28:47,206: INFO: proc(54): run_and_log_output: Output: if config.dbgpath is None: 2017-06-25 06:28:47,207: INFO: proc(54): run_and_log_output: Output: AttributeError: DumplingConfig instance has no attribute 'dbgpath' 2017-06-25 06:28:47,219: INFO: proc(54): run_and_log_output: Output: Trying to find crash dumps for project: System.Runtime.InteropServices.Tests 2017-06-25 06:28:47,219: INFO: proc(54): run_and_log_output: Output: Uploading dump file: /home/helixbot/dotnetbuild/work/dd100005-e671-46fb-892b-4e743335ba82/Work/10f58f6f-862f-44af-9628-ca1652b6bf2e/Unzip/core 2017-06-25 06:28:47,224: INFO: proc(54): run_and_log_output: Output: ~/dotnetbuild/work/dd100005-e671-46fb-892b-4e743335ba82/Work/10f58f6f-862f-44af-9628-ca1652b6bf2e/Unzip ``` @mellinoe " 21524 area-System.Drawing Add LinearGradientBrush tests Had this one lying around for a week or so but it can now be sent in without pesky merge conflicts 21525 area-Infrastructure Dumpling can't find dumps on some Linux distros eg suse and fedora 25.

Also, the latest plan of record for serialization support in .NET Core is such that serializing these exception types are not supported. So, removing the test for that. FYI, the actual implementation of the serialization overrides in the SmtpException class are already no-ops in the code and simply call the base method.

Since C# 6, we have the `nameof` operator which makes it great to pass the names of properties, methods, types, and so forth into attributes. The `ForeignKeyAttribute`, however, requires us to pass in a comma-separated string to specify multiple property names. Could we have a new constructor that accepts a `params string[]` and performs the concatenation, so that we can cleanly use the `ForeignKeyAttribute` with `nameof` to specify multiple names? 21537 area-System.Net Add WebSocket.CreateFromConnectedStream Several corefx components pull in the internal [ManagedWebSocket implementation](https://github.com/dotnet/corefx/blob/master/src/Common/src/System/Net/WebSockets/ManagedWebSocket.cs), both System.Net.WebSockets.Client on Unix and System.Net.HttpListener on Unix, and with https://github.com/dotnet/corefx/issues/9503 the plan is to use it in System.Net.WebSockets.Client on Windows 7 as well. Plus, ASP.NET uses the same implementation, via [source cloning](https://github.com/aspnet/WebSockets/blob/dev/src/Microsoft.AspNetCore.WebSockets/Internal/fx/src/Common/src/System/Net/WebSockets/ManagedWebSocket.cs). We should stop building this multiple times and instead expose it out through an API that anyone can use to wrap an established stream for a websockets connection. ```C# public abstract class WebSocket { public static WebSocket CreateFromConnectedStream( Stream stream, bool isServer, string subprotocol, TimeSpan keepAliveInterval, int receiveBufferSize, ArraySegment? receiveBuffer = null); ... } ``` Related to https://github.com/dotnet/corefx/issues/13663#issuecomment-265879275 Related to https://github.com/dotnet/corefx/issues/21509#issuecomment-310862176 Once this is added, we can stop compiling it into the various projects and just use the exposed API. Alternative: WebSocket currently exposes the following API: ```C# [EditorBrowsable(EditorBrowsableState.Never)] public static WebSocket CreateClientWebSocket(Stream innerStream, string subProtocol, int receiveBufferSize, int sendBufferSize, TimeSpan keepAliveInterval, bool useZeroMaskingKey, ArraySegment internalBuffer) ``` We could remove that EditorBrowsable(Never) and add a corresponding CreateServerWebSocket API. Both would effectively use CreateFromConnectedStream, just with a different value for isServer. However, it's not clear we could overload the meaning of CreateClientWebSocket in corefx to be what we need, given its current semantics on desktop, in particular as on desktop it uses WPSC and is documented as such.

For example: ```c# var uriComponentsOptions = UriComponents.AbsoluteUri; var uriFormatOptions = UriFormat.SafeUnescaped; var stringComparisonOptions = StringComparison.OrdinalIgnoreCase; var uriX = ""https://example.com/demo?param1=abc¶m2=xyz""; var uriY = ""https://example.com/demo?param2=xyz¶m1=abc""; //calling this URI would have the same affect as calling the above var result = Uri.Compare(uriX, uriY, uriComponentsOptions, uriFormatOptions, stringComparisonOptions); //yet this returns a non-zero value ``` **Suggestion** It would be helpful if there were a value for [UriComponents](https://msdn.microsoft.com/en-us/library/7767559y(v=vs.110).aspx) called `QueryIgnoreOrder` (or equivalent), allowing the query string of the URL to be compared without taking the order of the parameters into account. **Use Case** In automated test code, sometimes we need to compare URIs to ensure the correct URI is being generated. However, we don't care about the order of the parameters there, since that has no functional impact. We could code our tests to use fixed orders, but this would mean that any change to our code which altered that order would break our unit tests, creating more work to recode those strings for no real benefit. Currently I have this scenario / have had to code a workaround where my tests sort the parameters in key order before making a comparison (see https://stackoverflow.com/questions/44751296/uri-comparer-ignoring-query-string-order/44757683#44757683); but I'd hope that this would be something offerred by the .Net framework itself, as it feels a fairly common scenario / one of the key benefits of using Uri's Compare over a string comparison.

The idea with this issue is to discuss the design of a proposed _new_ implementation and API surface for `HttpClient` as part of the original issue. Some points discussed on that issue: 1. There are 2 different implementations of `HttpClient`. One on Windows (based on WinHttp) and other on *NIX world (based on libcurl) 2. It does not release all resources right away as most of people expect by a class implementing `IDisposable` (the TCP socket still leaking for a while by default for 240s due to `TIME_WAIT` state which makes you run out of available socket connections under high load) 3. There could be a internal pool similar to what exist in `SqlConnection`. However, it would probably hit worse issues with DNS cache, since it is managed by the OS networking stack and this implementation try to be 100% managed on top of the new *Foundation* layer proposed on the previous issue. 21569 area-System.Console Fix negative testing in System.Console.Tests Fixes https://github.com/dotnet/corefx/issues/21548 Stream.Null is supposed to be deaf, dumb and mute: https://msdn.microsoft.com/en-us/library/system.io.stream.null(v=vs.110).aspx and it is across CoreCLR, Desktop and N. Also, the test disabling attributes didn't match the stated intent in the comments. 21570 area-System.Net Make NetworkStream compatible with non-blocking I/O The predominant way to perform I/O is async. However, in some scenarios non-blocking I/O (or polling) is better adapted - the ability to read or write as much as possible, along with a guarantee that the call would not block. This allows retaining a very deterministic, single-thread model where I/O occurs opportunistically where the application chooses, rather than launching an asynchronous operation that may occur in parallel with other processes, require synchronization etc. Note that non-blocking is quite a common pattern in Unix (but not in Windows, which may explain the lack of support in .NET). Non-blocking I/O is currently supported at the Socket level by setting Blocking to true, and then calling Send and Receive. However, trying to construct a NetworkStream over a non-blocking socket throws an IOException (`The operation is not allowed on a non-blocking Socket`). Note that .NET's `Stream.Write()` returns void (unlike the [Linux write system call](http://man7.org/linux/man-pages/man2/write.2.html)). This probably means that the introduction of a new API element would be required to support non-blocking *writing*. 21571 area-Infrastructure Enabling CI for UWP F5 runs cc: @weshaggard @mmitche @danmosemsft @safern Now that our UWP F5 test run is clean, we are ready for adding this CI leg for uap tests.

The reflection wasn't working as expected. However, this same CookieParser.cs file is included in the System.Net.HttpListener library. And that reflection was working. It seems that reflecting on a type (Cookie) from within the same library (System.Net.Primitives) doesn't work from another type in that same library (CookieParser). It turns out that we can optimize this anyways and not use reflection when the file is included directly in System.Net.Primitives.

It's very possible that this issue is simply some change that was made to coreclr that fixed this and needs to be mirrored to corert. This issue is to track the work of fixing and enabling that test once its fixed. 21587 area-System.Net Remove outdated TODO in HttpClientHandler for UAP "The current behavior for .NET Core (Windows, *Nix, and UAP) is to use a default HTTP version if none or an illegal version is specified on the HttpRequestMessage.Version On .NET Framework, an exception is thrown in these cases, ""Only HTTP/1.0 and HTTP/1.1 version requests are currently supported."" This error message wouldn't make sense now anyways since HTTP/2 is supported in .NET Core. So, it is better to use a default version than to throw an exception.

They are using some defunct syntax that doesn't work or make sense anymore. > * Normalize comment style (lots of weird ""block-style"" header comments, weird comment spacing, etc.) This was a very rote cleanup. I just went through all of the files and did the following: * Change all XML comments to be of normal form, with `` tags, etc. There were a TON of comments that were empty, or just contained junk. I removed those. Others were of the correct form, but were formatted really strangely -- I fixed those up, too. * Removed duplicate comments. There were lots of comments right above the XML comment blocks which essentially said the exact same thing. I just removed these when I saw them. * Inside methods: cleaned up weird comment blocks where I saw them, deleted useless comments, empty comments, etc. * As I went, I also moved the ""using"" blocks up outside of the namespace, like all of the other files in corefx. This isn't related to the comments -- I just figured I would clean that up at the same time. There are no functional changes here. This is all code style cleanup. @hughbe @stephentoub Could you give this a quick look over? I know that it is quite large, but the changes are all very straightforward and formulaic.

Unfortunately, ClientWebSocket isn't handling those exceptions inside its MessageReceived event handler, so they end up bringing down the entire process.

First, ""default credentials"" are the current credentials of the logged-on user, typically on an enterprise network joined to an Active Directory domain. When these credentials are sent to a proxy or server, only Negotiate, Kerberos, or NTLM schemes are used. Those credentials can never be sent via other schemes like basic or digest. .NET Framework traditionally has two ways for developers to specify using default logged-on credentials to send to the server. Either set the .UseDefaultCredentials property to true or specify CredentialCache.DefaultCredentials to the .Credentials property. For proxy credentials, the developer could pass DefaultCredentials via the custom IProxy object or via the .DefaultProxyCredentials property. .NET Framework would send default credentials anywhere (intranet or internet) if specified by the developer. The UAP platform implementation of System.Net.Http uses a different set of rules for sending default credentials. It is based on whether the app has Enterprise Authentication capability as well as if the endpoint is specified in an intranet zone. This design is part of the base native WinInet and WinHTTP stacks. It was a design choice to provide optimum security as well as convenience for developers writing apps for enterprise scenarios. This PR does a few things. First, it keeps the .NET ICredentials properties stored separately so that they correctly round-trip on get and set. .NET NetworkCredential has 3 parameters (domain, user, password). But WinRT PasswordCredential only has 2 parameters (user, password). We now convert to the WinRT objects only when we need to use them. Second, this PR clarifies that the .UseDefaultCredentials property is basically a no-op because the API models of default credentials handling is different on the UAP platform as described above.

ManagedHandler-specific: - We currently write out a host header with a port number by converting the port to a string. This changes it to just write out the digits directly without the intermediate string. - HttpRequestHeaders is currently always allocated, even if it's never accessed by the developer code. - Parsing the response very likely yields at least once, and currently it's a helper that's called from the main SendAsync. It's easy to combine them and avoid the extra allocations from the extra async layer. - We're going to need to revisit the connection pooling anyway, but for now I was seeing allocations related to the ConcurrentDictionary show up. ConcurrentyDictionary is optimized for many-reads-fewer-writes, but this usage is entirely writes. CD just does striped locking for writes internally, so I replaced it with a simple striped-lock-HashSet structure that doesn't allocate on every add. - We're currently incurring an array enumerator allocation on every header being written out. We can avoid that with a cast. HttpClient-general: - Currently GetStream/String/ByteArrayAsync all incur a task allocation for getting the response stream. But in most cases, the stream is available promptly (it's the reads on the stream that are likely to be async). We can employ ValueTask to minimize the need for this allocation. - HttpRequestHeaders has 9 reference fields dedicated to specific lazily-allocated collection properties, and HttpResponseHeaders has 5. That's 112 bytes of fields allocated per request on 64-bit that are often unneeded. This puts them into a lazily-allocated array to make them more pay for play: they're a bit more expensive when used (the space for the array's overhead plus a cast on each use), but we avoid having to pay for the allocations for the fields when they're not used. Both: - Both HttpRequestHeader and HttpResponseHeader currently promptly allocate another wrapped HttpGeneralHeaders object, but this is only really necessary in the implementation when various strongly-typed properties are accessed. We can make it lazily-allocated and more pay-for-play. This changes the headers to be lazily-allocated, and then modifies the ManagedHandler to avoid accessing them unless necessary. cc: @davidsh, @geoffkizer 21680 area-System.Runtime System.Runtime.Extensions failures on UAPAOT "Currently those tests are disabled and need to be investigated ``` ```" 21681 area-Infrastructure Update to the latest intellisense package PTAL @ericstj FYI @Petermarcu 21684 area-System.IO Read only file system delete tests Tests to validate behavior for directory and file delete for read only file systems on Unix. 21685 area-Infrastructure Update prerelease label to preview2 release/uwp6.0 is going to use preview1 for now 21687 area-System.Threading "Fireball: No test result generated under ""System.Threading.Tasks.Parallel.Tests""" Detail: https://mc.dot.net/#/product/netcore/master/source/official~2Fcorefx~2Fmaster~2F/type/test~2Ffunctional~2Fcli~2F/build/20170629.01/workItem/System.Threading.Tasks.Parallel.Tests/wilogs Configuration: Windows.10.Nano.Amd64-x64:Release ~~~ 2017-06-29 01:28:38,927: INFO: proc(54): run_and_log_output: Output: Discovering: System.Threading.Tasks.Parallel.Tests 2017-06-29 01:28:39,069: INFO: proc(54): run_and_log_output: Output: Discovered: System.Threading.Tasks.Parallel.Tests 2017-06-29 01:28:39,147: INFO: proc(54): run_and_log_output: Output: Starting: System.Threading.Tasks.Parallel.Tests ~~~ 21688 area-Serialization Add desktop serialize test case @shmao Please help review the code. 21689 area-Microsoft.CSharp Length cannot be less than zero. thrown on nectoreapp2.0 when trying to invoke Action that accesses a property on the input class - works for anonymous types "_From @maumar on June 28, 2017 19:7_ repro: ```cs public class MyEntity { public int Id { get; set; } public string Name { get; set; } } [Fact] public virtual void Netcoreapp_bug() { Action workingElementAsserter = e => Console.WriteLine(""works""); Action failingElementAsserter = e => Console.WriteLine(e.Id); var dto = new MyEntity { Id = 1, Name = ""Foo"" }; var anonymous = new { Id = 1, Name = ""Foo"" }; workingElementAsserter(dto); //works failingElementAsserter(anonymous); //works failingElementAsserter.Invoke(dto); //fails } ``` exception: ``` System.ArgumentOutOfRangeException : Length cannot be less than zero.

We found this issue on RedHat 7.3 with $LANG and $LC_ALL set to ""zh_CN.GBK"". It works well with Chines character with UTF-8 encoding. The issue can be reproduced by following code: ```c# using System; using System.IO; namespace netcoretest { class Program { static void Main(string[] args) { foreach (var fileItem in Directory.EnumerateFileSystemEntries(""."", ""*"", SearchOption.TopDirectoryOnly)) { Console.WriteLine(fileItem); } } } } ``` It reports an error as following: ``` Unhandled Exception: System.ArgumentException: Illegal characters in path. Parameter name: path at System.IO.PathInternal.CheckInvalidPathChars(String path) at System.IO.Path.Combine(String path1, String path2) at System.IO.UnixFileSystem.FileSystemEnumerable`1.d__11.MoveNext() at netcoretest.Program.Main(String[] args) in /home/xtest/netcoretest/Program.cs:line 10 Aborted (core dumped) ``` GBK is an encoding standard defined by China. Does .Net Core framework have plan to support other encoding besides Unicode? If so, could you share your schedule?

After the first set it may not happen immediately and the value is dependent on the fact if Windows has already changed it (this usually happens really quickly but is not quick enough for stress testing) Simple repro showing the issue: ```csharp for (int i = 0; i < 1000; i++) { foreach (var culture in cultures) { var c = culture; CultureInfo.CurrentCulture = c; Assert.Equal(c.LCID, CultureInfo.CurrentCulture.LCID); } } // example cultures are hu-HU, invariant, en-US ``` This has failed 100% of the time on my local box 21741 area-System.Runtime GCHandle double-free in GCHandleTests This case https://github.com/dotnet/corefx/blob/954d7199ffd45537e89aa1b15b3cc38df56f58e1/src/System.Runtime.InteropServices/tests/System/Runtime/InteropServices/GCHandleTests.cs#L125 is causing the GCHandle to be double-freed here https://github.com/dotnet/corefx/blob/954d7199ffd45537e89aa1b15b3cc38df56f58e1/src/System.Runtime.InteropServices/tests/System/Runtime/InteropServices/GCHandleTests.cs#L151 It leads to intermittent crashes with release CoreCLR build, and asserts with debug CoreCLR build. 21742 area-System.Net Removing ActiveIssue attributes.

It looks like there is a bug in latest .NET native. We should not require people to add WindowsRuntimeBuffer in rd.xml. @tijoytom Can you help take a look? The exception diff seems to be a result of overly aggressive optimization. I remember @hoyMS mentioned something like this in the past. If we keep running into issues like these, we should consider turning off that particular optimization, at least in our testing. And if that optimization doesn't bring us a lot of value, we should consider simply turn it off in the compiler by default. The failing tests were fixed by updating the `rd.xml` file.

This eliminates the behavioral difference between .NET Core and UWP tracked by issue #21102. This fix leverages WinRT APIs that are only present since Windows 10 Insider Preview Build 16215, so API presence checks are in place. The pre-fix behavior takes effect when running on older Windows builds. Fixes #21102 CC: @mconnew 21756 area-System.Collections Avoid boxing HashBucket This avoids the boxing cost of `ImmutableHashSet+HashBucket` and fixes equality checks during rebalancing so that the contents of any hash collisions are considered. This fixes: 1. performance 1. data corruption on AoT platforms 1. data corruption due to improper tree rebalancing on any platform in edge cases of hash collisions. At least in theory. I haven't written a test to prove it. This makes `ImmutableHashSet` follow the same pattern as `ImmutableDictionary` for equating `HashBucket` instances. Fixes #19044 21758 area-System.Runtime Re-enable one System.Runtime.Extensions Evironment_Exit test and fix it for UAP Contributes: https://github.com/dotnet/corefx/issues/21415 The test CheckExitCode was failing because: 1. RemoteExecutor for UAP always checks that the invoke exit code is SuccessExitCode (42). Since the intention of this test was to check an specific exit code because we where manipulating the process through a parameter to tell it to set that exit code it was failing since it was different than 42. To solve this I added an ExpectedExitCode to the RemoteInvokeOptions class which defaults to SuccessExitCode but this allows testing to override that exit code if for some reason the test should expect for a different one. 2. Even after I fixed that they where failing with NullReferenceException because we where trying to access the exit code from RemoteExecutor's result process, but for UAP this process is set to true. So I decided to split the tests. cc: @tarekgh @joperezr @danmosemsft 21761 area-System.Net SslStream bug on Linux/OSX: Interop+OpenSsl+SslException: SSL Handshake failed with OpenSSL error "**`dotnet --version` output:** 1.0.1 The bug is present on Ubuntu, but not on Windows 7.

Please help review the code. 21763 area-System.Net [Proposal] Change internal type name System.Net.WebFileStream to System.Net.FileWebStream After porting one of my projects from .NET Framework 4.6.1 to netcoreapp2.0 target I have noticed some failing tests due to a tests dependency on netfx internal type name System.Net.FileWebStream. This type has different name in .Net Core - [System.Net.WebFileStream](https://github.com/dotnet/corefx/blob/master/src/System.Net.Requests/src/System/Net/FileWebRequest.cs#L311). Although I am aware of consequences of taking dependencies on internal framework types (they are not guaranteed to not change in the future) I think that in this case it would be reasonable to use identical type names for types performing the very same functions across related frameworks. Going even further it could be quite useful to have this type exposed in public API as it is exposed publicly anyway as a return type of some framework methods i.e. ```C# public Stream System.Net.WebClient.OpenRead(Uri uri); ``` That change would allow safe use of return type in scenarios where it is used to differentiate source of data returned. 21764 area-System.Drawing Add Graphics property tests 21765 area-System.Linq Modernise C# style within System.Linq In particular, `is`-with patterns is applicable quite a few places. 21766 area-System.Data System.Data.SqlClient .NET Core 2.0 Preview 2 - Unable to load DLL 'sni.dll': The specified module could not be found.

For full context, see #21642 I’m now working on #21102 (out for PR - #21755) and the new code that references new APIs compiles just fine. However, running the UWP tests (i.e., msbuild /t:rebuildandtest /p:TargetGroup=uap) leads to a bunch of MissingMethodExceptions, such as: > System.Exception: Unknown ---> System.MissingMethodException: Method not found: 'Void Window > s.Networking.Sockets.MessageWebSocketControl.put_ReceiveMode(Windows.Networking.Sockets.MessageWebSocketReceiveMode)' All new API calls are guarded by _IsPropertyPresent_ checks already, and the code is executing on a machine that contains the new APIs (which is why the new code attempts to use them). After some analysis, we realized that these exceptions are due to the test runner’s UWP app having been compiled against an old Windows 10 SDK. Could you please help us update the test runner to be compiled against the RS3 16225 SDK? :) Please, let me know how I can help. P.S. Compiling against pre-RS3 SDKs won’t be supported for NETStandard20, so this is just a test issue. P.P.S. All tests pass in UAPAOT mode, since they execute outside of a UWP package.

When I tried to implement the retry logic, I found out that * The passed-in `HttpContent` contained in `HttpRequestMessage` got disposed in `HttpClient.SendAsync`. * The underlying `Stream` in `StreamContent` [got disposed](https://github.com/dotnet/corefx/blob/6bf1e7c3032d3c24d5a41bbd880549ef4a8de2da/src/System.Net.Http/src/System/Net/Http/StreamContent.cs#L85) in `StreamContent.Dispose()` invocation. This means that if I have passed in a `Stream` in `StreamContent`'s ctor, the very `Stream` will be inevitably disposed after the first `HttpClient.SendAsync` invocation. This is not good, especially if the `StreamContent`-user is agnostic about how to reconstruct another brand-new `Stream` instance (but still can seek the position so the `Stream` will be at the same position as it is in the first call, as long as its `CanSeek` is `true`). I ended up writing [my own version of `StreamContent`](https://github.com/CXuesong/WikiClientLibrary/blob/3a3ece77923beb31956afee973e72e17fe1d2f4f/WikiClientLibrary/HttpContentEx.cs#L65) that won't dispose the underlying `Stream` when disposed. Still, I hope there will be some `leaveOpen`-like parameter in the constructor of `StreamContent`, like [the constructor of `StreamReader`](https://github.com/dotnet/corefx/blob/6bf1e7c3032d3c24d5a41bbd880549ef4a8de2da/src/System.Runtime.Extensions/src/System/IO/StreamReader.cs#L140). 21792 area-System.Memory Rename AsSpan to AsReadOnlySpan Fix #20242 @ahsonkhan 21793 area-System.Net HttpClient.GetAsync() causes uncatchable CryptographicException on Linux in OpenSslX509ChainProcessor.MapVerifyErrorToChainStatus "System: Ubuntu 16.04 and Ubuntu 16.10 Dotnet release: dotnet-dev-1.0.4 apt list --installed | grep dotnet output: ``` dotnet-dev-1.0.4/yakkety,now 1.0.4-1 amd64 [installed] dotnet-host/yakkety,now 2.0.0-preview2-25407-01-1 amd64 [installed,automatic] dotnet-hostfxr-1.1.0/yakkety,now 1.1.0-1 amd64 [installed,automatic] dotnet-sharedframework-microsoft.netcore.app-1.1.2/yakkety,now 1.1.2-1 amd64 [installed,automatic] ``` apt list --installed | grep openssl output: ``` libgnutls-openssl27/yakkety-updates,yakkety-security,now 3.5.3-5ubuntu1.2 amd64 [installed] openssl/yakkety-updates,now 1.0.2g-1ubuntu9.3 amd64 [installed] ``` Repro Code: ``` using System; using System.Net.Http; using System.Threading.Tasks; namespace Repro { class Program { static void Main(string[] args) { Do().GetAwaiter().GetResult(); } static async Task Do() { var client = new HttpClient(); try { var response = await client.GetAsync((new Uri(""https://obr03.ru/""))); Console.WriteLine(""Ok""); } catch(Exception ex) { Console.WriteLine(""Catched""); } } } } ``` Result Windows: `Catched` Result Linux: ``` Unhandled Exception: System.Security.Cryptography.CryptographicException: Error occurred during a cryptographic operation. at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.MapVerifyErrorToChainStatus(X509VerifyStatusCode code) at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.AddElementStatus(X509VerifyStatusCode errorCode, List`1 elementStatus, List`1 overallStatus) at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.AddElementStatus(List`1 errorCodes, List`1 elementStatus, List`1 overallStatus) at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.BuildChain(X509Certificate2 leaf, HashSet`1 candidates, HashSet`1 downloaded, HashSet`1 systemTrusted, OidCollection applicationPolicy, OidCollection certificatePolicy, X509RevocationMode revocationMode, X509RevocationFlag revocationFlag, DateTime verificationTime, TimeSpan& remainingDownloadTime) at Internal.Cryptography.Pal.ChainPal.BuildChain(Boolean useMachineContext, ICertificatePal cert, X509Certificate2Collection extraStore, OidCollection applicationPolicy, OidCollection certificatePolicy, X509RevocationMode revocationMode, X509RevocationFlag revocationFlag, DateTime verificationTime, TimeSpan timeout) at System.Security.Cryptography.X509Certificates.X509Chain.Build(X509Certificate2 certificate) at System.Net.Security.CertificateValidation.BuildChainAndVerifyProperties(X509Chain chain, 509Certificate2 remoteCertificate, Boolean checkCertName, String hostName) at System.Net.Http.CurlHandler.SslProvider.VerifyCertChain(IntPtr storeCtxPtr, IntPtr curlPtr) at Interop.Http.MultiPerform(SafeCurlMultiHandle multiHandle) at System.Net.Http.CurlHandler.MultiAgent.WorkerBodyLoop() Aborted (core dumped) ``` " 21795 area-System.Linq Remove checked floating negate instructions from S.L.Expressions Since checked/unchecked context has no effect on floating-point operations, `NegateCheckedSingle` is effectively a duplicate of `NegateSingle` and `NegateCheckedDouble` of `NegateDouble`.

For certain kinds of bad certs, that manipulation may end up throwing an exception, which accidentally is allowed to propagate out of the managed callback back across the interop boundary, which is unsupported and ends up crashing. The fix is simply to expand the existing catch block to prevent such exceptions from propagating and instead appropriately marshal them to the request that should be failed. In addition, this particular failure triggers a debug fail fast in X509Certificates due to an unrecognized status code while trying to map error codes to chain status. I've added the particular error code to avoid the assert, but it looks like there are other missing codes as well, so we should subsequently review those missing codes to determine whether they should also be added. Contributes to https://github.com/dotnet/corefx/issues/21793 (fixes it, but we should aim to port the fix to 2.0 if possible, so keeping it open) cc: @bartonjs, @janvorli, @geoffkizer, @Qowy 21803 area-Meta Port Winforms to CoreFX As the porting of System.Drawing from the Mono code is in progress what are the possibilities to have Winforms ported to CoreFX?

If we build them in chk mode the tests run successfully. The exception thrown that is causing them to crash is the following: ``` Unhandled exception at 0x581410DF (mrt100_app.dll) in xunit.console.netcore.exe: 0xC0000005: Access violation reading location 0x00000000. ``` One place where I've got the debugger to break on this exception was: https://github.com/dotnet/corefx/blob/master/src/System.Linq.Parallel/src/System/Linq/Parallel/Utils/GrowingArray.cs#L27 Note that this only happens in ret mode for the following configurations: - Debug x86 - Release x86 - Release Arm - Debug Arm This seems to be a codegen bug when running optimization. cc: @kouvel @danmosemsft @joshfree 21805 area-System.Linq Fix System.Linq.Parallel.Tests for UapAot by building them on chk mode only Since they where a lot of tests to disable and the debugger just crashes I think this is the best workaround to have the tests running and producing testResults.xml - please see: https://github.com/dotnet/corefx/issues/21804 cc: @kouvel @danmosemsft @joshfree 21806 area-System.Linq Compile Boolean != as ^ in System.Linq.Expressions Boolean and lifted Boolean `!=` is identical to `^` in results. In the case of the interpreter this allows for one type, and its memoising field, to be removed, so do so. In the case of the compiler this allows for a slightly shorter CIL output. Detecting this adds to the compilation complexity, but also inlining `EmitUnliftedEquality` into `EmitUnliftedBinaryOp` can remove a branch on two tests so the nett result is simpler. 21807 area-Infrastructure Groovy failing in CI for Linux x64 Release Build `Caused: java.lang.IllegalArgumentException: Failed to prepare archiveArtifacts step` at https://ci3.dot.net/job/dotnet_corefx/job/master/job/linux-TGroup_netcoreapp+CGroup_Release+AGroup_x64+TestOuter_false_prtest/741/console and other runs. 21808 area-System.Net Enable more ManagedHandler tests cc: @geoffkizer 21809 area-System.Runtime Proposal: CallerArgumentExpressionAttribute ## Rationale In order to facilitate the language feature at https://github.com/dotnet/csharplang/issues/287, which has been championed and discussed in the LDM, we should add `CallerArgumentExpressionAttribute` to the framework. The LDM notes seem to approve of getting this into the framework: see [here](https://github.com/dotnet/csharplang/blob/master/meetings/2017/LDM-2017-05-16.md#callerargumentexpression). ## Proposal ```cs namespace System.Runtime.CompilerServices { [AttributeUsage(AttributeTargets.Parameter, AllowMultiple = false, Inherited = false)] public sealed class CallerArgumentExpressionAttribute : Attribute { public CallerArgumentExpressionAttribute(string parameterName); // Added in response to @svick's comment public string ParameterName { get; } } } ``` ## Notes - The name of the constructor argument is intentionally `parameterName` and not `argumentName`. Parameters refer to the variables declared inside the callee, while arguments are the values passed by the caller. ![image](https://user-images.githubusercontent.com/9159214/27773044-483c57ac-5f3e-11e7-9a87-50876915a518.png) 21810 area-Meta .NET Core should consider having the equivalent of Windows.Devices.* Filing based on feedback: https://docs.microsoft.com/en-us/uwp/api/ There are lots of basic device operations from GPIO, I2C, to Bluetooth that should be really easy to do on all devices when using .NET Core. 21811 area-System.Security DSA-SHA1 SignedXml issues .netcore 2.0 "I have a SAMLlibrary which I am trying to piece together on .net core 2.0, however I have hit an issue it some pre-existing tests.

We cannot get grid of unsafe code completely since there are stack-vs-heap paths based on stackalloc, but all the pointer based stuff should gracefully disappear; I think. I'm interested to dive into this, after the summer or so. " 21833 area-System.Security .NET should expose a generalized ASN.1 reader/writer API A lot of features in cryptography and X.509 certificates rely on the ability to read or write ASN.1-structured data. Not only would a good API for ASN.1 reading/writing simplify some of our existing code, it's very handy when someone wants to try adding support for something we don't have inbox, like reading a new certificate extension. There are a couple of different aspects to the problem: ## 1) What do inputs/outputs look like? One of the harder parts to remember to get right is rejecting unexpected data. For example, from https://tools.ietf.org/html/rfc3280#section-4.1.1.2: ```asn AlgorithmIdentifier ::= SEQUENCE { algorithm OBJECT IDENTIFIER, parameters ANY DEFINED BY algorithm OPTIONAL } ``` The `AlgorithmIdentifier` structure defines two, and only two fields. If a third field is present the data is invalid. (In our current internal implementation this means you need `if (reader.HasData) throw new CryptographicException();` at the end of reading it). This means that we really don't want to have to resort to a ReadNext() type API, since it's easy to do it poorly. One strawman is to build on the model of existing serializers, so one would so something like ```C# [StructLayout(StructLayoutKind.Sequential)] internal struct AlgorithmIdentifier { internal ObjectIdentifier Algorithm; [Optional] internal ??? Parameters; } ``` The fact that the first example drew a need for a base class might be telling that it needs to be a Sequential-layout class instead of a struct. Or maybe ASN-ANY has to be a byte[] that gets reinterpreted by the caller (but the serializer validates that it was legally encoded). But sequential ordering on the type seems like a requirement. C-based libraries generally seem to solve this problem with macro-based template languages. So maybe a template is the way to go. But, maybe not. Needs to consider: * OPTIONAL (DER says never to write down ASN-NULL for an OPTIONAL value) * DEFAULT (DER says to never write down a default value) * Sometimes a default is on a complex type (like saying that a default AlgorithmIdentifier is SHA-2-256). * ANY * Context-specific tagging * And Application-specific, and Private. I suppose * That tags *technically* are not constrained to one-byte values. * Collections (arrays/etc) can be SEQUENCE OF (write them down in the order I gave you) or SET OF (write them down in a proscribed order) * This *could* be skipped in the encoder and declared to be a problem for the data provider; but since the sort order for SET OF frequently comes down to the data length (before data values) it is sort of hard for them to do it right. * ASN INTEGER is C# BigInteger. But also supporting Int32/Int64/etc has virtue. * There are lots of string encodings in ASN * I'm sure floating point is unpleasant. * DateTime values can be pretty weird. X.509 adds more restrictions than DER does. Is that an encoding? An attribute? A post-deserialization validation? * Any other quirks that exist when combining ITU-T X.680 (ASN), ITU-T X.690 (BER/CER/DER) and C#. ## 2) What encodings are supported? ITU-T X.690 defines 3 different encoding rulesets: * BER (Basic Encoding Rules) * CER (Canonical Encoding Rules) * DER (Distinguished Encoding Rules) Generally speaking; BER defines all the possibilities for representing data, CER describes a set of restrictions on BER, and DER describes even more restrictions. Occasionally CER and DER give conflicting recommendations, though. * Read-as-BER can read anything. * Read-as-CER (maybe) should reject an octet-string with a primitive encoding in excess of 1000 octets (ITU-T REC X.690 2015-08 section 9.2) * (Maybe there needs to be CER-strict and CER-flexible?) * Read-as-DER should (definitely) reject any indefinite length encoding (ITU-T REC X.690 2015-08 section 10.1). Almost all things in cryptography use DER, making DER a minimum bar. But, since [CMS / S/MIME / PKCS#7](https://tools.ietf.org/html/rfc2315) says that it's designed to allow BER indefinite length encodings, there are clearly cases where readers need to be more flexible. (Windows and OpenSSL both write all CMS objects with DER; macOS uses indefinite length encodings) ## 3) What does an API look like? Largely this comes out of the inputs/outputs section, but encodings need to be taken into account. ```C# public static AsnEncoding { public static ???? Encode(T value, AsnEncodingType type, Span output); public static ???? Decode(ReadOnlySpan input, } ``` If there's a base class then there could be an OnDeserialize()-style validation callback per hydrated member. If it's a convention that ends up being reflection, which isn't super fun. So maybe it's just up to the user... but that's somewhat annoying for embedded structures. Particularly through OPTIONAL. ----- It probably makes sense to try to design the API, and use it internally, and then eventually expose it (essentially letting internal consumption be the proving ground). 21835 area-System.Text System.Text.RegularExpressions.Tests.Match_SpecialUnicodeCharacters* is failing on UAP This test is failing because of combination of two windows bugs: - setting a culture to invariant does not always happen - turkish I should not be lowercased to i on en-US This test is being renamed to System.Text.RegularExpressions.Tests.Match_SpecialUnicodeCharacters_Invariant in https://github.com/dotnet/corefx/pull/21782 @tarekgh, could you provide details? 21837 area-System.Diagnostics some style fixes While working on the IntelliSense for EventCounter, I stumbled upon this topic. If the bold/italic styling is done inside a fenced block, it won't work. BTW, is this something we should transform in an official doc? There would be some work involved since this is written in a very informal way. I also don't know what you mean on item 3 (line 37). 21838 area-System.Security Fix segfault on chain build on macOS High Sierra When building a cert chain for self-issued certificates on High Sierra, Security.framework gets into a bad state. One minute after entering SecTrustEvaluate the function exits with the trust result set to Invalid and the return value (an OSStatus) set to success. Continuing to interact with that chain results in more slowdowns and/or a null-dereference triggering a segfault. Hopefully the underlying issue is fixed before 10.13 RTM, but for now we can be less destructive by throwing an exception instead of letting the native code terminate the process. This addresses #21436 in master, but we'll probably want to backport the fix to 2.0.

FileStream.ctor default for FileShare is FileShare.Read, but File.Open's default is FileShare.None. In Windows, FileAccess maps to GENERIC_READ and/or GENERIC_WRITE, and FileShare to FILE_SHARE_READ, FILE_SHARE_WRITE, and/or ""FILE_SHARE_NONE"". The valid combinations for CreateFile calls are shown here: https://msdn.microsoft.com/en-us/library/windows/desktop/aa363874(v=vs.85).aspx. Essentially the file access required must be allowed by other handles' file share values. So if an existing handle has GENERIC_READ, other handles must all include FILE_SHARE_READ. I didn't look at Unix. In this case the tests opened the icon file with a FileStream using FileMode.Open passed, and therefore the defaults of FileAccess.ReadWrite and FileShare.Read. Other tests called the Icon constructor which opened the icon file with `new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read)`. The FileAccess.ReadWrite is not compatible with the FileShare.Read, causing the error. The fix is to explicitly request FileAccess.Read in the tests. Also noticed a use of File.Open with the default values of FileAccess.ReadWrite and FileShare.None. Since it's just reading from the file, it seems reasonable to pass FileAccess.Read, FileShare.Read explicitly, so another notional process could read concurrently." 21847 area-System.IO Port fix to DriveInfo for apple FS Fixes #21597 Port #21636 to release/2.0.0 21850 area-Infrastructure "No test result generated under ""System.Xml.RW.XmlWriterApi.Tests""" "No test result generated under ""System.Xml.RW.XmlWriterApi.Tests"" Detail: https://mc.dot.net/#/product/netcore/master/source/official~2Fcorefx~2Fmaster~2F/type/test~2Ffunctional~2Fuwp~2F/build/20170704.01/workItem/System.Xml.RW.XmlWriterApi.Tests/wilogs Configuration: Windows.10.Amd64.ClientRS3-x86 Windows.10.Arm64-arm ~~~ 2017-07-03 19:42:18,296: INFO: proc(54): run_and_log_output: Output: Got manifest file appxmanifest.xml 2017-07-03 19:42:18,391: INFO: proc(54): run_and_log_output: Output: Removing any previous installation... 2017-07-03 19:42:18,391: INFO: proc(54): run_and_log_output: Output: Installing the application... 2017-07-03 19:42:19,578: INFO: proc(54): run_and_log_output: Output: Package ID is 5cd54353-3ed7-4a6e-a72f-db349f28867c_1.0.0.0_arm__v52bfwc2c21ha 2017-07-03 19:42:19,609: INFO: proc(54): run_and_log_output: Output: Starting the application... 2017-07-03 19:42:19,609: INFO: proc(54): run_and_log_output: Output: Resolved Folder Path: C:\Users\DotNetTestRunner\AppData\Local\Packages\5cd54353-3ed7-4a6e-a72f-db349f28867c_v52bfwc2c21ha\ 2017-07-03 19:42:20,203: INFO: proc(54): run_and_log_output: Output: Waiting for the application to exit... 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: Process has just exited with return code 255. 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: Disabling the debugger... 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: STDOUT & STDERR from imersive process: 2017-07-03 19:42:31,871: INFO: proc(54): run_and_log_output: Output: ================================================================================== 2017-07-03 19:42:31,887: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:31,887: INFO: proc(54): run_and_log_output: Output: ================================================================================== 2017-07-03 19:42:31,887: INFO: proc(54): run_and_log_output: Output: Removing the application... 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: SUCCESS 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: ExitCode 255 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: C:\dotnetbuild\work\074ab7a5-2eef-42da-8843-793c057a4837\Work\141c2691-75ba-443e-99a1-c81258f7bb52\Unzip>move C:\Users\DotNetTestRunner\Documents\TestResults\System.Xml.RW.XmlWriterApi.Tests.dll.xml .\testResults.xml 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: The system cannot find the file specified. 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: C:\dotnetbuild\work\074ab7a5-2eef-42da-8843-793c057a4837\Work\141c2691-75ba-443e-99a1-c81258f7bb52\Unzip>move C:\Users\DotNetTestRunner\Documents\TestResults\System.Xml.RW.XmlWriterApi.Tests.dll.txt .\logs.txt 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: The system cannot find the file specified. 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: C:\dotnetbuild\work\074ab7a5-2eef-42da-8843-793c057a4837\Work\141c2691-75ba-443e-99a1-c81258f7bb52\Unzip>type logs.txt 2017-07-03 19:42:33,437: INFO: proc(54): run_and_log_output: Output: The system cannot find the file specified. 2017-07-03 19:42:33,453: INFO: proc(54): run_and_log_output: Output: Finished running tests.

To investigate a failure of `init-tools`, content of the log will be helpful. Hence this change attempts to display the content of `init-tools.log` to console. This is done by adding a task in build definition that does a `cat` or `type` of `init-tools.log`. This task runs only when a previous task that runs `init-tools` command fails. Another solution I thought was to update the command itself such that there is an option for verbose output, which I think is nicer, and costlier. @ellismg PTAL. 21895 area-System.Diagnostics Fix issues in ProcessManager.Win32 Issues are mentioned in https://github.com/dotnet/corefx/pull/21746.

In .NET Framework, any exception bubbling out of a user-provided callback is trapped, saved, and placed as an inner exception to the main HttpRequestException that is thrown. This is the current behavior of HttpClient on .NET Framework. Even for HttpWebRequest on .NET Framework, the exception is placed as an inner exception to the top-level WebException. Currently, .NET Core is throwing a raw exception from the callback and propagating it as a top-level exception for HttpClient APIs. This bad pattern started with WinHttpHandler when I introduced (unknowingly) the bug. The behavior was then copied to the *Nix version. This current test is therefore invalid: ```c# [Fact] public async Task UseCallback_CallbackThrowsException_ExceptionPropagates() { // ... var handler = new HttpClientHandler(); using (var client = new HttpClient(handler)) { var e = new DivideByZeroException(); handler.ServerCertificateCustomValidationCallback = delegate { throw e; }; Assert.Same(e, await Assert.ThrowsAsync(() => client.GetAsync(Configuration.Http.SecureRemoteEchoServer))); } } ``` In my PR #21905 implementing ServerCertificateCustomValidationCallback for UWP, I have revised this test and disabled it on all platforms except UAP. 21905 area-System.Net Fix HttpClientHandler ServerCertificateCustomValidationCallback for UWP This PR implements the ServerCertificateCustomValidationCallback for UWP. While implementing this, I discovered that the behavior of the current .NET Core code is incorrect regarding how to propagate exceptions from the user provided callback.

The first client cert that can be successfully converted into a WinRT client cert (if any) is configured on the underlying WinRT MessageWebSocket instance, leading to the cert being used for mutual TLS authentication when establishing connections with WSS endpoints. This fix leverages WinRT APIs that are only present since Windows 10 Insider Preview Build 16215, so API presence checks are in place.

A quick audit of the X509Chains built in the test library showed that these were effectively the only ones which didn't set their VerificationTime value, and by having NotBefore be ""now"" when the certs are created, they were very sensitive to backwards clock adjustments.

The options are to disable reflect block on System.Xml.* which may cause the application size to be larger. To get past this issue, the recommendation is to change the CreateSqlReader visibility to public in System.Private.Xml and take a dependency on the private assembly.

The failures occur in two different tests, but only if both tests are enabled. Running each test separately while disabling the other makes the tests pass. The problem is actually due to a known issue in WinRT Windows.Web.Http.HttpClient layer. The WinRT layer uses native WinInet and there are some things that WinInet caches per-process and not per-session handle. That means that there is unintended sharing of some state between separate HttpClient objects. In particular, this shared state is about TCP connections and specifically if SSL connections were made using cert error ignore flags. We have two tests were the tests are testing against connecting to servers with bad certificates. ```c# public static readonly object[][] CertificateValidationServers = { new object[] { Configuration.Http.ExpiredCertRemoteServer }, new object[] { Configuration.Http.SelfSignedCertRemoteServer }, new object[] { Configuration.Http.WrongHostNameCertRemoteServer }, }; [OuterLoop] // TODO: Issue #11345 [ConditionalTheory(nameof(ClientSupportsDHECipherSuites))] [MemberData(nameof(CertificateValidationServers))] public async Task NoCallback_BadCertificate_ThrowsException(string url) { using (var client = new HttpClient()) { await Assert.ThrowsAsync(() => client.GetAsync(url)); } } [OuterLoop] // TODO: Issue #11345 [ConditionalTheory(nameof(BackendSupportsCustomCertificateHandlingAndClientSupportsDHECipherSuites))] [MemberData(nameof(CertificateValidationServersAndExpectedPolicies))] public async Task UseCallback_BadCertificate_ExpectedPolicyErrors(string url, SslPolicyErrors expectedErrors) ``` In one test, we use no callback and expect to get errors. In another test, we connect to the same servers and pass it a callback. We use the callback to analyze the certificate errors from the X509Chain we get back. The problem occurs in the no_callback test where we expect to get an HttpRequestException back. But we don't because the other test which ran in parallel or just before already used ignore flags, made good connections at the TCP/SSL layer, so Wininet caches those connections for later use. So, the no_callback test fails because the connections are already there. One way to work around this problem in the tests is to isolate each of the two tests into separate processes using the RemoteExecutor. In a previous release of Windows 10, the WinRT HttpClient APIs added a new method to the HttpBaseProtocolFilter: https://docs.microsoft.com/en-us/uwp/api/windows.web.http.filters.httpbaseprotocolfilter That new method ```c# public void ClearAuthenticationCache() ``` allows developers to clear out any cached connection information if their app is running long-term and they need to do ""log off"" scenarios. However, at the System.Net.Http layer, we don't have that control, nor do we expect it since the assumption is that connections are cached per HttpClient. So, this is a difference in behaviors, unfortunately, for now.

At this point, we should stop using it in our UWP binaries. That means API that enumerates and examines arbitrary processes should be stubbed to thrown PNSE with a nice message.

I then want to instantiate the `Startup` class and hand it over to the `TestHost` API, so I can start the site in memory. I've written the following code: ```c# var directoryPath = @""C:\Dlls""; var assemblyFilePath = Path.Combine(directoryPath, ""Foo.dll""); var assemblyName = AssemblyLoadContext.GetAssemblyName(assemblyFilePath); var assembly = new AssemblyLoader(directoryPath).LoadFromAssemblyName(assemblyName); var startupType = assembly.ExportedTypes .FirstOrDefault(x => string.Equals(x.Name, ""Startup"")); var webHostBuilder = new WebHostBuilder() .UseStartup(startupType) .UseUrls(new string[] { ""http://localhost"" }); using (var testServer = new TestServer(webHostBuilder)) { var response = testServer.CreateClient().GetAsync(""/""); } public class AssemblyLoader : AssemblyLoadContext { private readonly string directoryPath; public AssemblyLoader(string directoryPath) => this.directoryPath = directoryPath; protected override Assembly Load(AssemblyName assemblyName) { var dependencyContext = DependencyContext.Default; var compilationLibraries = dependencyContext .CompileLibraries .Where(x => x.Name.Contains(assemblyName.Name)) .ToList(); if (compilationLibraries.Count > 0) { return Assembly.Load(new AssemblyName(compilationLibraries.First().Name)); } else { var file = new FileInfo($""{this.directoryPath}{Path.DirectorySeparatorChar}{assemblyName.Name}.dll""); if (File.Exists(file.FullName)) { var asemblyLoader = new AssemblyLoader(file.DirectoryName); return asemblyLoader.LoadFromAssemblyPath(file.FullName); } } return Assembly.Load(assemblyName); } } ``` This works when I publish the app as a self contained application, however, I'd like to avoid dealing with runtime identifiers (RID's) if possible. When I publish normally the code throws a `TypeLoadException` when `assembly.ExportedTypes` is called. The full stack trace: ``` System.TypeLoadException occurred HResult=0x80131522 Message=Method 'ConfigureServices' in type 'Foo.Startup' from assembly 'Foo, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Attached is the minimal project I can think of to reproduce the exception.

b__0() in c:\users\lextm\documents\visual studio 2017\Projects\SocketAsyncClose\SocketAsyncClose\Program.cs:line 36 ``` This piece of code tries to reuse `SocketAsyncEventArgs` objects. And it works fine if `Socket.ReceiveAsync` or `Socket.ReceiveFromAsync` is used. I tested it on Windows 10 (latest patches, .NET Core 1.0 and 1.1), and both cases give the same exception. I tested on macOS (latest stable. .NET Core 1.0 and 1.1), and cannot reproduce the exception. Not surprised, as it should be something wrong in `SocketAsyncEventArgs.Windows.cs` I think and is Windows only. 21996 area-System.Net Fix handling of SslStream.None on Linux "First commit refactors and augments SslStreamSystemDefaultTests to test not only default-to-default, but also default-to-other stuff and both explicitly and implicitly specifying the default. The tests fail on Linux before the second commit. Second commit makes two changes: - Currently if None is specified, we end up disabling all protocols! OpenSSL will then end up negotiating something very limited, and for example using None on the client won't be able to connect to a Tls12 server. - If an explicit version is used, on the server we end up only allowing connections from clients sending that specific version's hello message, which means a client sending an earlier version but with support for upgrading to a newer is explicitly denied, which means on Unix a None can't connect to a Tls12, for example. The fix for the first issue is to simply allow None to mean what was intended, the system default, and not override OpenSSL's default if None is specified. The fix for the second issue is to simplify how protocol limitation is done. Currently we both select the ""proper"" version method and then set context options. Instead, we always use SSLv23_method, which the docs recommend, and then just use the context options to restrict the allowed protocol.

Then in order to use the buffer, it pins it, storing both a GCHandle and a pointer to the target object. But if the SAEA's buffer is ever changed with, for example, a SetBuffer call, a routine is invoked on the SocketAsyncEventArgs that frees all of its pinned data, including these for the _wsaMessageBuffer. Then the next time ReceiveMessageFromAsync is used, this handle ends up not getting recreated, and we end up dereferencing a null pointer. The essentially-one-line fix is to separate the creation of the buffer from the creation of the pinning handle, lazily initializing each independently. If the pinning handle is freed due to SetBuffer, the next invocation will reinitialize it. I also consolidated and augmented the existing ReceiveMessageFromAsync tests to test multiple receives with the same SocketAsyncEventArgs in order to catch this case. The test now fails before the fix and passes after.

If `WaitNamedPipe` succeeds then the code calls `CreateNamedPipeClient` (`CreateFile`) and if that returns any error other than ""pipe busy"" it throws an exception. If the server dies between the call to `WaitNamedPipe` and `CreateNamedPipeClient` you'll end up with an unexpected `FileNotFoundException`.

Currently applications make programmatic decisions for it via `ToString()` which has a couple of problems: * It's localized on Windows * It's not the same on Windows and !Windows. Rather than exposing the whole GeneralName concept (and dealing with X400Address) the type would * Exist * Allow enumerating the DNSName entries * Maybe allow enumerating the IPAddress entries * Probably have a `MatchesHostname(string)` method * Maybe have a `MatchesIPAddress(IPAddress)` method. It might make sense to put `MatchesHostname` on X509Certificate2, just to make things easier. 22072 area-System.Net Re-enabling ClientWebSocket close and cancel tests in UWP "Re-enabling ClientWebSocket's CloseTest and CancelTest runs for UWP. All of these tests pass after a minor behavioral fix, where the ""cancel pending ReceiveAsync"" scenario was resulting in a different exception type compared to .NET Framework and non-UWP .NET Core. The following CancelTest test cases caught the bad behavior that I'm fixing as part of this PR: - ReceiveAsync_CancelThenReceive_ThrowsOperationCanceledException - ReceiveAsync_ReceiveThenCancel_ThrowsOperationCanceledException - ReceiveAsync_AfterCancellationDoReceiveAsync_ThrowsWebSocketException Contributes to #20132" 22073 area-System.ComponentModel Add Container tests and fix a debug assertion 22074 area-Microsoft.CSharp Remove InputFile and KAID from Microsoft.CSharp `InputFile` relates to source files in Rotor and doesn't affect behaviour in dynamic code. Related to this, a type cannot be unresolved in dynamic code, as it comes from existing types, so there's no need to track it. Our starting point is the runtime type, so the references to assemblies are not necessary as with static compilation, hence e.g. `PredefinedTypes._aidMsCorLib` being calculated and then never used. Trimming out unused elements related to this, and the elements those removals make unused, results in `KAID` being removed completely. Also remove some unused method parameters. 22075 area-System.Net Fix HttpClientHandler UAP to use a filtered set of client certs My earlier PR #22022 refactored the GetEligibleClientCertificates code into a Common method. However, I neglected to actually use it in the UAP HttpClientHandler! Fixed the handler to properly filter down the set of client certificates. Added new tests to verify functionality. While doing this, I discovered that the tests need to run in an isolated process due to the per-process caching behavior of the UAP HTTP stack. So, I used the RemoteInvoke method. I had to duplicate some of the new tests using Fact instead of using Theory. This is because the RemoteInvoke doesn't allow non-string parameters and I had to pass in X509Certificate2 objects. So, I separated out each variant into its own Fact test. 22076 area-System.Runtime LoadUnmanagedDllFromPath / LoadUnmanagedDll is not working on linux if .so file is present in any other path other than application output directory Hi , i am not sure whether the issue exists in coreclr or corefx.

So tracing that lot through shows that this is dead code. `BindImplicitConversionRequireOneArgument` has a path that is much as the above and another from `RuntimeBinder.BindCall` which also always sets a single argument, so again this is dead code.

That in turn loads some other dlls, some of which are netstandard2.

I had thought this was part of netstandard, but either way I've added it as a NuGet package dependency to the Unity project (seeing as that's the one that does dynamic loading), but for some reason it's not ending up in either the Unity project bin folder or the exe one.

When using ReceiveMessageFromAsync multiple times with the same SocketAsyncEventArgs and buffer, it ends up allocating a pinning handle on every call and not freeing one that might already exist. This results in leaking a GCHandle per call. As verification, I ran essentially the test at https://github.com/dotnet/corefx/blob/master/src/System.Net.Sockets/tests/FunctionalTests/ReceiveMessageFromAsync.cs#L37 but with an infinite number of iterations rather than with 5. Prior to the fix, memory usage climbs consistently and quickly.

I changed the target used for master branch builds to `GetAllSymbolFilesToPublish` rather than `UnzipSymbolPackagesForPublish` so that we create converted symbols even if we aren't going to archive them. (We index them on symweb using VSTS Symbol.) On a current CoreFX master build, this new extra target takes ~14 seconds. Windows builds produce Windows PDBs right now, so it only converted PDBs for the Linux and OSX symbol packages. This is part of https://github.com/dotnet/core-eng/issues/698.

The test seems to be failing because the first behavior type argument passed is invalid and thus gets ValueType.HashCode()=0 as hash code by default, and the second one is of behavior type Duration, which has 0 time span and as a result, returns 0 for hash code. I'm not 100% sure what the purpose of the test was, but looks like to me the failure should be expected given the input. So, enforcing non-zero timespan for the second arg. cc: @hughbe @tijoytom 22180 area-System.Security [release/2.0] Disable tests on High Sierra which trigger corrupt chains "Whatever bad loop is currently present on High Sierra with building self-signed chains with revocation enabled seems to be inside a critical section, so any other tests running concurrently have a chance of hitting the ""took too long"" internal timeout and reporting an invalid chain, too. Avoiding calling Verify on a self-signed cert in TestVerify and avoiding TestResetMethod (whose first chain has revocation enabled) results in all tests passing with parallelism enabled across ~60 sequential runs on High Sierra Beta2.

"Hello, guys! When I used the method LoadXml from RSAKeyValue.cs, I was always receiving the following exception: `System.Security.Cryptography.CryptographicException: 'Root element must be KeyValue element in namepsace http://www.w3.org/2000/09/xmldsig#'` After searching for some bug, I've found that the second IF statement inside LoadXml is verifying if value.Name (instead of value.LocalName) is different from ""KeyValue"". Because of that, when this method receives any XmlElement that has namespace prefix, it will throw the exception above. Code with the bug: ```csharp if (value.Name != KeyValueElementName || value.NamespaceURI != SignedXml.XmlDsigNamespaceUrl) { throw new CryptographicException($""Root element must be {KeyValueElementName} element in namepsace {SignedXml.XmlDsigNamespaceUrl}""); } ``` How I think it should be: ```csharp if (value.LocalName != KeyValueElementName || value.NamespaceURI != SignedXml.XmlDsigNamespaceUrl) { throw new CryptographicException($""Root element must be {KeyValueElementName} element in namepsace {SignedXml.XmlDsigNamespaceUrl}""); } ``` By the way, you could also fix the ""namepsace"" inside the CryptographicException message hehe.

I find it extremely unlikely that anybody would ever care about this functionality going away: it looks incredibly obscure, and not that useful in the first place.

Windows [docs state](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx) (emphasis mine) and IsPathRooted implements this behavior: > **Fully Qualified vs. Relative Paths** > For Windows API functions that manipulate files, file names can often be relative to the current directory, while some APIs require a fully qualified path. _**A file name is relative to the current directory if it does not begin**_ with one of the following: > - A UNC name of any format, which always start with two backslash characters (""\\""). For more information, see the next section. > - A disk designator with a backslash, for example ""C:\"" or ""d:\"". > - **_A single backslash, for example, ""\directory"" or ""\file.txt"". This is also referred to as an absolute path._** However, that last point is incorrect. A path of `\directory' or '\file.txt' is treated as _relative_ to the root of the current directory as this clearly demonstrates: ``` C# Environment.CurrentDirectory = @""C:\Temp""; Console.WriteLine(Path.GetFullPath(@""\Foo"")); Environment.CurrentDirectory = @""D:\""; Console.WriteLine(Path.GetFullPath(@""\Foo"")); ``` Which outputs: ``` C:\Foo D:\Foo ``` Inside VS we need to answer; _will this path change based on the current directory?_. IsPathRooted does not supply that - whereas, Uri does: ``` C# Console.WriteLine(""Path.IsPathRooted: "" + Path.IsPathRooted(@""\Foo"")); Console.WriteLine(""Uri.TryCreate: "" + Uri.TryCreate(@""\Foo"", UriKind.Absolute, out Uri result)); ``` Which outputs: ``` Path.IsPathRooted: True Uri.TryCreate: False ``` I suspect what Windows docs is referring to and what IsPathRooted is actually handling, is the _device namespace_, such as `\Device\HarddiskVolume4` but as far as I'm aware you cannot use that syntax via Win32, you need to prepend; `\\.\`." 22246 area-System.Linq Don't double-cast in nullable-to-nullable coalesce S.L.Expressions If a coalesce of a nullable has the same type as the expression (e.g. `x ?? y` if both `x` and `y` are int?) then not looking for this case means if the lhs isn't null it's cast to non-nullable then back to nullable again.

But, `Stream`, `TextWriter` and `TextReader` does have async methods. As async programming is widely used today, to serialize/deserialize data contracts, developer should manually schedule background task to achieve async data contracts serialization/deserialization on stream (which itself does support async I/O out of the box!) I propose extend DataContractSerializer to have built-in task-based async serialization/deserialization methods. 22258 area-Microsoft.CSharp Make Microsoft.CSharp.RuntimeBinder.Semantics.CType.StripNubs virtual and not loop The `T??` case can't happen since we're basing our types on actual existing so there are only two cases; it's called on `NullableType`, in which case we return `UnderlyingType` or it's called on something else, in which case we return `this`.

The PR is to fix those issues.

The PR fixed the following issues: 1. When writing collection object the element type of the collection was not correctly set, which caused the type info was not correctly written in the payload. Test type: `SampleListTExplicitWithoutDC`. The fix is ported from `XmlFormatWriterGenerator.CriticalHelper.WriteCollection`. 2. DCS couldn't correctly de-serialize generic dictionary in certain cases. Test type: `MyGenericIDictionaryKVContainsPublicDC`. 3. DCS couldn't de-serialize collection type with private `Add` method. Test type: `CDC_PrivateAdd`. 4. DCS couldn't de-serialize collection type with private constructor. Test type: `CDC_PrivateDefaultCtor`.

Once Read/WriteAsync in Stream is fixed on ILC, the code should be undone. 22331 area-Microsoft.CSharp Microsoft.CSharp binder not prepared for mis-called static calls. "If we set up a dynamic call-site as follows; ```C# var site = CallSite>.Create( Binder.InvokeMember( CSharpBinderFlags.None, ""Equals"", null, GetType(), new[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.IsStaticType, null), CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null), CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) } ) ); Func target = site.Target; ``` Then `target` can now be used to call a static method called `Equals` as in e.g. `target(site, typeof(object), ""A"", ""A"")` returning true. The binder is not prepared for the consumer incorrectly calling it with a non-type as the second argument, throwing `RuntimeBinderInternalCompilerException` with a message of ""An unexpected exception occurred while binding a dynamic operation"", or in debug mode triggering an assertion. Rather than an exception that ""represents a malfunctioning of the runtime binder itself"", it should be an `ArgumentException` (or arguably a `RuntimeBinderException`, but AE matches some similar cases)." 22332 area-System.Linq Span and friends may require work in Linq.Expression/DLR and dynamic binders It is not permitted to box these types and expressions/binders would need to know about that. Otherwise there could be some relatively trivial ways to cause failures such as dynamically invoking a Span-returning method by name. That would easily result in a Span being boxed, which might fail very ungracefully. 22333 area-Microsoft.CSharp Microsoft.CSharp: Catch passing non-type as type for bound static call "If something other than a `Type` is passed as the second argument (first after the `CallSite`) then catch this and throw an explanatory `ArgumentException`, rather than a `RuntimeBinderInternalCompilerException` describing it as ""unexpected"". Also remove assertion this cannot happen, as it clearly can. Conversely, replace check that would throw `RuntimeBinderInternalCompilerException` for this case in `CreateCallingObjectForCall` with just an assertion, as the above check will have happened before this point could be reached. Fixes #22331" 22335 area-System.Diagnostics Investigate Ways to Reduce Dependence on Reflection for EventSource EventSources currently require reflection for both manifest-based logging and tracelogging. The latter is required, because there is no concept of subclasses or event methods - just calls to Write public methods on EventSources. However, we can do better with manifest-based logging. There is currently an IL transform in the toolchain that triggers for a well-known set of EventSources in the framework and pre-generates metadata for them so that reflection is not used at runtime. We should consider expanding this transform for two cases: 1. Automatically detect reflection blocked types and pre-generate metadata for them, rather than having to explicitly opt the types in. 2. Support localized resources (the current transform does not support this). 22336 area-System.Security Fixed issue #22229, where RSAKeyValue.LoadXml was throwing a CryptographicException when receiving a XmlElement with namespace prefix as input Fixed bug on element name check in RSAKeyValue which caused error when element had a namespace prefix; Implemented a test case.

Contributes to #19583 22339 area-System.Diagnostics [DiagnosticsSource] http correlation protocol should optionally support intrinsic sort "Related to issue #22284 The current version of the Hierarchical Request Format mandates uniqueness. But analytics on tracing formats which are vector clock based, also rely on the format providing a sort without depending on other event properties such as Time. To provide such a sort as well as provide uniqueness, the elements in the vector have to support a monotonic sequence. The current protocol is cited as follows: > Suffix MUST be unique for every outgoing HTTP request sent while processing the incoming request; monotonically incremented number of outgoing request within the scope of this incoming operation, is a good candidate. But there is insufficient information if the value is actually a monotonic sequence. Also, a benefit of explicitly supporting a numeric format incremented from 0 is improved wire cost when compared to a randomly generated suffix. The proposed changes are follows: - Distinguish vector elements to be either a number (on which a sort is possible) or an entropy element, using a prefix character: ""#"". Number can be typed to unsigned 64 bit max. - Provide a way to enable ""atomic increments"" mode in the built-in .NET implementation. If enabled, this would create atomic increments of the current vector element on the outgoing path, as opposed to simply generating randomized suffixes and the prefix character described above would be applied on the latter case. - If the ""atomic increments"" mode is turned on for a component that is initializing a root request id, it should generate X.0. - Similarly, if the ""atomic increments"" mode is turned on, and if the incoming value of the Request Id is ""X."", then the value should be ""X.0"" (if the ""trusted caller"" mode is on as per #22284) or ""X.[Entropy_0]"" otherwise. @vancem, @lmolkova, @SergeyKanzhelev" 22341 area-System.IO Update tests for pending whitespace trimming changes Update tests for pending whitespace trimming changes (see: https://github.com/dotnet/coreclr/pull/12862) 22343 area-System.Runtime AppDomain events have wrong sender ``` AppDomain.UnhandledExceptionEventHandler AppDomain.AssemblyLoadEventHandler AppDomain.ResolveEventHandler AppDomain.FirstChanceException AppDomain.ProcessExit ... ``` The sender argument for these events should be AppDomain.CurrentDomain, but it is actually the internal AppDomain object. #22330 fixed this for FirstChanceException event on uapaot only. This should be fixed for all of the events and for both CoreCLR and CoreRT. Also, tests should be added. We may consider fixing this by moving AppDomain back to CoreLib. Having it in CoreFX seems to have less and less value. 22345 area-System.IO Add method IsPathFullyQualified() to replace IsPathRooted() for returning if a path is relative "A common mistake is to assume that `IsPathRooted()` paths cannot be relative. To make the distinction between rooted and relative clear, `Path` should implement a `IsPathFullyQualified()` method that returns whether or not changing the current directory will change the path. Details in issue #22245 ## Rationale and Usage Currently, `IsPathRooted()` does not answer the question of whether changing the current directory will change a given path. Adding `IsPathFullyQualified()` will more explicitly and correctly address this question. Note: `IsPathRelative()` may seem like a more intuitive name for the method to be added. However, `IsPathRelative()` suggests that the method determines whether or not the path contains '.' or '..', which is not true. `IsPathFullyQualified()` is broader and addresses whether the path will change based on the current directory. This terminology is also consistent with [documentation.](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#fully_qualified_vs._relative_paths) ## Proposed API ``` c# /// /// Returns false if the path specified is relative to the current drive or working directory. /// Returns true if the path is fixed to a specific drive or UNC path. This method does no /// validation of the path (URIs will be returned as relative as a result). /// /// /// Handles paths that use the alternate directory separator. It is a frequent mistake to /// assume that rooted paths (Path.IsPathRooted) are not relative. This isn't the case. /// ""C:a"" is drive relative- meaning that it will be resolved against the current directory /// for C: (rooted, but relative). ""C:\a"" is rooted and not relative (the current directory /// will not be used to modify the path). /// public static bool IsPathFullyQualified(string path) ``` ## Details Doesn't handle URIs (will say all URIs are relative). ## Open Questions N/A ## Pull Request N/A ## Updates " 22347 area-Infrastructure CI issue: Error during cleanup: java.io.IOException: in OSX Debug https://ci3.dot.net/job/dotnet_corefx/job/master/job/osx-TGroup_netcoreapp+CGroup_Debug+AGroup_x64+TestOuter_false_prtest/1318/console https://ci3.dot.net/job/dotnet_corefx/job/master/job/osx-TGroup_netcoreapp+CGroup_Debug+AGroup_x64+TestOuter_false_prtest/1316/console and a few more in the last couple of hours. 22348 area-System.Runtime System.Runtime.Serialization.Formatters.Tests failing in UapAot Tests are failing with error: ``` The stored blob for type System.TimeZoneInfo+AdjustmentRule is outdated and needs to be updated.\r\nStored blob: 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\r\nGenerated runtime blob: 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\r\nExpected: True\r\nActual: False ``` Stack Trace: ``` at System.Runtime.Serialization.Formatters.Tests.BinaryFormatterTests.SanityCheckBlob(Object obj, String[] blobs) at System.Runtime.Serialization.Formatters.Tests.BinaryFormatterTests.ValidateAgainstBlobs(Object obj, String[] blobs) at Object _$ILCT$+$ILT$ReflectionDynamicInvoke$.InvokeRetVII[T0, T1](Object, IntPtr, InvokeUtils+ArgSetupState&, Boolean) + 0x6f at Object System.InvokeUtils+CalliIntrinsics.Call(IntPtr, IntPtr, Object, IntPtr, InvokeUtils+ArgSetupState&, Boolean) + 0x55 at Object System.InvokeUtils.CallDynamicInvokeMethod(Object, IntPtr, Object, IntPtr, IntPtr, Object, Object[], BinderBundle, Boolean, Boolean) + 0x171 ``` https://mc.dot.net/#/product/netcore/master/source/official~2Fcorefx~2Fmaster~2F/type/test~2Ffunctional~2Filc~2F/build/20170717.02/workItem/System.Runtime.Serialization.Formatters.Tests/analysis/xunit/System.Runtime.Serialization.Formatters.Tests.BinaryFormatterTests~2FValidateAgainstBlobs(obj:%20AdjustmentRule%20%7B%20DateEnd%20=%201955-12-31T00:00:00.0000000,%20DateStart%20=%201900-01-01T00:00:00.0000000,%20Da... 22349 area-System.Net Converted sudo commands to class helper Use new sudo admin helper class. 22350 area-System.Threading System.Threading.Tasks.Tests are failing in UapAot -

The `NextBytes(byte[])` base method is implemented in terms of `InternalSample`, but `NextBytes(Span)` shouldn't be implemented in terms of that, as it's not public and thus an existing derived type couldn't have overridden it, and thus the new virtual wouldn't pick up existing behaviors. It also shouldn't be in terms of `NextBytes(byte[])`, as that would require allocating/copying an array, largely defeating the purpose of the method (at least for the base class). But since `Next()` on the base class just delegates to `InternalSample()`, `Next()` is a reasonable thing to base the implementation on, e.g. ```C# public virtual void NextBytes(Span buffer) { for (int i = 0; i < buffer.Length; i++) { buffer[i] = (byte)(Next() & 0xFF); } } ``` 22358 area-System.Runtime Add DateTime{Offset} Span-based APIs Separated out of https://github.com/dotnet/corefx/issues/21281 for tracking purposes. - [x] Implement in System.Private.CoreLib in coreclr (corert shares the same files) - [x] Expose from System.Runtime contract in corefx - [x] Add tests to System.Runtime tests in corefx ```C# namespace System { public struct DateTime { public static DateTime Parse(ReadOnlySpan s, IFormatProvider provider = null, System.Globalization.DateTimeStyles styles = DateTimeStyles.None); public static DateTime ParseExact(ReadOnlySpan s, string format, IFormatProvider provider, DateTimeStyles style = DateTimeStyles.None); public static DateTime ParseExact(ReadOnlySpan s, string[] formats, IFormatProvider provider, DateTimeStyles style); public static bool TryParse(ReadOnlySpan s, out DateTime result, IFormatProvider provider = null, DateTimeStyles styles = DateTimeStyles.None); public static bool TryParseExact(ReadOnlySpan s, string format, IFormatProvider provider, DateTimeStyles style, out DateTime result); public static bool TryParseExact(ReadOnlySpan s, string[] formats, IFormatProvider provider, DateTimeStyles style, out DateTime result); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider provider = null); … } public struct DateTimeOffset { public static DateTimeOffset Parse(ReadOnlySpan input, IFormatProvider formatProvider = null, System.Globalization.DateTimeStyles styles = DateTimeStyles.None); public static DateTimeOffset ParseExact(ReadOnlySpan input, string format, IFormatProvider formatProvider, DateTimeStyles styles = DateTimeStyles.None); public static DateTimeOffset ParseExact(ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, DateTimeStyles styles); public static bool TryParse(ReadOnlySpan input, out DateTimeOffset result, IFormatProvider formatProvider = null, DateTimeStyles styles = DateTimeStyles.None); public static bool TryParseExact(ReadOnlySpan input, string format, IFormatProvider formatProvider, DateTimeStyles styles, out DateTimeOffset result); public static bool TryParseExact(ReadOnlySpan input, string[] formats, IFormatProvider formatProvider, DateTimeStyles styles, out DateTimeOffset result); public bool TryFormat(Span destination, out int charsWritten, string format = null, IFormatProvider formatProvider = null); … } } ``` 22360 area-System.Data "Test: System.Data.Tests.SqlTypes.SqlBooleanTest/ToSqlInt64 failed with ""Xunit.Sdk.EqualException""" Opened on behalf of @Jiayili1 The test `System.Data.Tests.SqlTypes.SqlBooleanTest/ToSqlInt64` has failed.

Consequentially, this test fails on systems that do not have short path alias generation enabled.

It’s possible we could get away with reimplementing `MemoryStream` on top of `Buffer`, but more than likely this would introduce regressions for at least some existing use cases, and it doesn't work with `ReadOnlyBuffer`. It would be nice if we could potentially write something ala: ```C# Stream s = buffer.TryGetArray(out var segment) ? new MemoryStream(segment.Array, segment.Offset, segment.Count) : new UnmanagedMemoryStream(&buffer.DangerousGetPinnableReference(), buffer.Length); ``` but it's possible that TryGetArray could return false but the wrapped memory not inherently pinned, in which case the UnmanagedMemoryStream case would be wrapping a pointer to memory that could get moved. To pin it and keep track of the pinning, you'd need a wrapper Stream type anyway. So, we could have two new stream types for these specific types: ```C# namespace System.IO { public class BufferStream : Stream { public BufferStream(Buffer buffer); public BufferStream(Buffer buffer, bool publiclyVisible); public bool TryGetBuffer(out Buffer buffer); … // overrides of all members on Stream } public class ReadOnlyBufferStream : Stream { public ReadOnlyBufferStream(ReadOnlyBuffer buffer); public ReadOnlyBufferStream(ReadOnlyBuffer buffer, bool publiclyVisible); public bool TryGetBuffer(out ReadOnlyBuffer buffer); … // overrides of all members on Stream, with those that write throwing NotSupportedException } } ``` The name of BufferStream is unfortunately close to that of BufferedStream, and they mean very different things, but I’m not sure that’s important enough to consider a less meaningful name. Alternatively, we could hide these behind a factory, e.g. ```C# public static Stream ToStream(this Buffer buffer) => new BufferStream(buffer); public static Stream ToStream(this ReadOnlyBuffer buffer) => new ReadOnlyBufferStream(buffer); ``` to keep them from needing to be public. Especially if we do the latter, we would want to consider either adding TryGetBuffer virtuals to the base Stream class, or introducing an interface that could be queried for and which exposing such methods. Then for example code that uses Streams and has optimizations when working directly with the underlying data can query for the interface and special-case when the underlying `Buffer` can be accessed, e.g. ```C# namespace System { public interface IHasBuffer { bool TryGetBuffer(out Buffer buffer); bool TryGetBuffer(out ReadOnlyBuffer buffer); } } ``` We could implement this not only on `BufferStream` and `ReadOnlyBufferStream`, but also on `MemoryStream`, `UnmanagedMemoryStream`, and even on non-streams, basically anything that can hand out a representation of its internals as buffers. 22405 area-System.Runtime Consider adding BitConverter overloads that accept endian option #22355 lists APIs we're planning to add that use `Span` instead of `byte[]`. These and the existing methods also use the current machine's endianness. We should separately consider overloads that accept the endianness to use, rather than always using that of the current machine, e.g. ```C# public static bool TryWriteBytes(Span destination, long value, bool? littleEndian); public static long ToInt64(ReadOnlySpan value, bool? littleEndian); // null littleEndian means current machine's ``` or ```C# public enum Endianness { Current, Little, Big } public static bool TryWriteBytes(Span destination, long value, Endianness endianness); public static long ToInt64(ReadOnlySpan value, Endianness endiannes); ```` cc: @bartonjs 22406 area-System.Runtime Add TextReader and TextWriter Span/Buffer-based APIs Separated out of https://github.com/dotnet/corefx/issues/21281 for tracking purposes. - [x] Implement in System.Runtime.Extensions - [x] Expose from System.Runtime.Extensions contract - [x] Add tests to System.Runtime.Extensions.Tests ```C# namespace System.IO { public class TextReader { public virtual int Read(Span destination); public virtual ValueTask ReadAsync(Buffer destination, CancellationToken cancellationToken = default(CancellationToken)); public virtual int ReadBlock(Span destination); public virtual ValueTask ReadBlockAsync(Buffer destination, CancellationToken cancellationToken = default(CancellationToken)); … } public class TextWriter { public virtual void Write(ReadOnlySpan source); public virtual Task WriteAsync(ReadOnlyBuffer source, CancellationToken cancellationToken = default(CancellationToken)); public virtual void WriteLine(ReadOnlySpan source); public virtual Task WriteLineAsync(ReadOnlyBuffer source, CancellationToken cancellationToken = default(CancellationToken)); … } } ``` EDIT 7/25/2017: Updated with CancellationTokens per API review. 22407 area-System.IO Tweak path related tests Needed to update a few tests for unix whitespace behavior. 22408 area-System.IO Override new Span/Buffer-based APIs on StreamReader Depends on https://github.com/dotnet/corefx/issues/22406. 22409 area-System.IO Override new Span/Buffer-based APIs on StreamWriter Depends on #22406. 22410 area-System.IO Override new Span/Buffer-based APIs on StringReader Depends on #22406. 22411 area-System.IO Override new Span/Buffer-based APIs on StringWriter Depends on #22406. 22412 area-System.Runtime Add TransformationStatus enum from corefxlab Based on corefxlab work, will be used by a variety of new corefx Span-based APIs.

An overload of CreateViewAccessor() with no parameters is provided for the common case that the view is to cover the entire file. That overload results in a DefaultSize value of zero being passed to the size parameter of MemoryMappedView.CreateView(). Line 38 of the file MemoryMappedView.Windows.cs calls a check, preceded by a comment: // if request is >= than total virtual, then MapViewOfFile will fail with meaningless error message // ""the parameter is incorrect""; this provides better error message in advance Interop.CheckForAvailableVirtualMemory(nativeSize); The problem is that ""nativeSize"" as implemented is zero under the (most?) common case just mentioned, such that the check (in Interop.Windows.cs) is not very probative: if (nativeSize >= totalVirtual) { throw new IOException(SR.IO_NotEnoughMemory); } Now the one caller (MemoryMappedFile) of MemoryMappedView.CreateView() has the actual file length (from its FileStream, or from a native call). On line 152 of MemoryMappedFile it ensures that the filestream.length is meaningful under the default capacity/size scenario, so it could readily provide it to MemoryMappedView.CreateView() to enable an accurate lower-bound expected memory consumption calculation and check before the Pinvoke call to MapViewOfFile. (By considering both the system page size as well as the allocation granularity it is straightforward to calculate a value that matches the viewInfo.RegionSize that is later returned by the existing VirtualQuery call.) Given that this problem is not resulting in a catastrophic failure (only a ""meaningless error message,"" per the comment in the code) and that it may not be all that common to be mapping views of large files exceeding the available virtual memory, I'm unsure where this fits in the grand scheme of priorities. However, I wanted to log it given that I found myself adding a remedy today in my own specialized implementation in case someone eventually logs a bug on this.

This can be extended to skip reading the right operand if the left is null (the result will always be the same as leaving the current null value on the stack) and reducing field accesses, so do so. 22421 area-System.Data Make DataCommonEventSource members public on uapaot, since reflection needed for EventSource functionality is blocked in UAP for nonpublic members. Fixes https://github.com/dotnet/corefx/issues/20589 The DataCommonEventSource members need to be marked public on uapaot in order for EventSource reflection to work. TestEventListener in DataCommonEventSourceTest enables events based on the event name, which is retrieved via reflection. Not enabling any events is what is causing the test failures in the above issue. I tried the ILTransform solution mentioned by @brianrob in https://github.com/dotnet/corefx/issues/20589, but the test runs fail since the event method at https://github.com/dotnet/corefx/blob/master/src/System.Data.Common/src/System/Data/Common/DataCommonEventSource.cs#L69 has a non-void return type. According to Brian, Events normally shouldn't work at all with a non-void return type, but so far this is the only issue we've seen with that event method. Marking the event source members public is less invasive than changing all the calls to DataCommonEventSource.EnterScope() that would be needed to make the ILTransform fix work 22422 area-System.Diagnostics Fixed races in EventCounters There were a number of races in EventCounters.

The existing implementation of `X509Certificate2` is pretty much hard-coded to use `RSACryptoServiceProvider` or `DSACryptoServiceProvider` on Windows. Not sure about the other platforms. My use case is that I'd like a way to support Azure Key Vault-backed certificates in a clean way and that appears impossible today. There is virtually nothing on the base class that can be overridden and the extension methods `GetRSAPublicKey` and `GetRSAPrivateKey` are pretty much hard-coded to `RSACng` and `RSACryptoServiceProvider` right now. My ideal goal is that I could create an `AzureKeyVaultX509Certificate` class that derives from `X509Certificate2` and that end users can work with the same as existing certificates. The constructor would take a `KeyVaultClient` and `KeyBundle` so that it would know the key identifier and public key. Sign and Decrypt operations would go to the Key Vault client instead of any native API. Calls to the `GetRSAPrivateKey` would get a custom implementation of `RSA` that knows how to call into Key Vault. 22440 area-System.Numerics Add more Math operation support System.Numerics.Vectors Support for some SIMD instructions are missing in Numerics.Vectors Vector.RootN //Only SquareRoot is implemented Vector.Exp //Every element of the result is exp(a,b) where a,b are input vectors Vector.LShift //Shift elements in a by elements in b Vector.RShift //Like above would simulate a = b >> c for all elements It wondsers me because Or and XOr is there but not shift.

The reason why costumers could hit this is if they add into their Application's resources or consume a library that their resources have key/values like the example below: ```xml Object ObjectGetSetProperty ObjectNoSuchProperty ``` Where a resource is the Prefix of the full property name (Class.PropertyName). If we have this resources structure inside a UWP app when building it will fail with an error similar to this one: ``` error PRI175 : 0x80073b0f - Processing Resources failed with error : Duplicate Entry. error PRI278: 0xdef00531 - 'Resources.TestResx/Object' or one if its parents is defined as both resource and scope, which is not allowed. ``` We will need to provide an additional separator to our customers to have a valid workaround here rather than changing the ""Default"" resource (I suggest '-').

It contains only Base64 and ""-"" (hyphen), ""|"" (vertical bar), ""."" (dot), and ""_"" (underscore) characters. This max length is designed to accommodate the hierarchical request format which maintains a growing vector of elements. Assuming an average of two digit increments for outgoing paths, each stage requires 12 bytes : - 9 bytes (8 random characters + '_') - 2 digits - '.' This translates to about 83 vector elements after taking into account the root. While this may seem plentiful, it is still bounded and a kb is considerable overhead for tracking correlation on a web request. To address this, can we consider the following: - Allow for unbounded growth by resetting the vector. So when the vector at max length is received on the incoming path, the suffix is hashed and the Request-Id reinitialized with the first element being the hashed value. We can rely on a standard 64 bit hash to distinguish this from a regular element. - Reduce the max length to something like 128 bytes (which incidentally is the same max length for the cV 2.0) which should be sufficient for approximately 8 stages before being reset. For context, the cV does not support reset semantics. But this would allow for shorter max lengths and unbounded traces which are desirable traits for the next version." 22453 area-System.Security SqlConnection.Open fails with SSL error on macOS High Sierra (10.13) "SqlClient connections to any SQL Server instance fails on macOS High Sierra.

The removal of this dead code of course needs to be careful of removing a condition that actually could happen, in which case a test cases that hit it should be added or if that's difficult for some reason the condition should be clearly documented in a comment. This issue is to track that. The following is a list of all errors not currently hit during testing. This isn't a perfect to-do list (the same error could have both possible and impossible paths to it) and it includes some cases that I think should definitely be reachable (but they should be covered by tests anyway for #14345 and marked off as soon as confirmed as reachable, and besides I could be wrong), but it will serve as a gauge.

This fixes the last uapaot serialization failure. Disabling the test is safe as the difference in the blob is a field which exists in coreclr but not in corert which handles Unix daylightsavings scenarios. For UWP6.0 this isn't required and therefore disabling the test case till the TimeZoneInfo is fully converged isn't an issue. 22508 area-System.Reflection Value 0x0010 for DllCharacteristics is missing In corefx/src/System.Reflection.Metadata/src/System/Reflection/PortableExecutable/PEFileFlags.cs, there is no value for 0x0010 listed. I cannot find it documented anywhere, however if I build a native DLL with cl.exe and pass /APPCONTAINER to the linker, this bit is present in the resulting PE file's DllCharacteristics field. While the link.exe documentation for /APPCONTAINER isn't clear whether it actually applies to DLLs, the fact that the C# compiler only has a single /out:library option as opposed to separate /out:winexe and /out:appcontainerexe options would seem to indicate that it doesn't apply. Can someone check with the Visual C++ compiler team to find out what the value of 0x0010 is in DllCharacteristics and if it has anything to do with building a DLL with /APPCONTAINER, or is just a coincidence as a result of /APPCONTAINER activating other options in the reuslting output? 22509 area-Infrastructure Overriding the RID for build.sh I'm building the coreclr, corefx, and cli repos for Amazon Linux. When I build the corefx repo I run into issues because the build scripts and tools don't handle the RID 'amzn.2015.09-x64' properly. I originally tried to fix the build scripts in the corefx repo to override the RID, instead of deriving from /etc/os-release. But there are scripts and tools that get downloaded as part of the build that reference the /etc/os-release file too. The temporary workaround I'm using is to change the /etc/os-release file to make the tools think they're running on 'rhel.7-x64', since Amazon Linux is closest to that distro. When I change /etc/os-release the build and tests work. That's not a long term solution though, since it's not safe to change that file permanently. Do you have any suggestions on how to override the RID globally for the duration of the build? 22511 area-Microsoft.CSharp Some optimisations for Microsoft.CSharp.RuntimeBinder.SymbolTable * Merge ClearCache() into ctor * Switch in IsOperator Don't keep hitting virtual property, and don't repeat checks. * Only get name property once per method when hunting conversions. * Make two never-used return types void. * Add parameter conversions during AddNamesOnType rather than looping twice * Don't create store results in AddNamesInInheritanceHierarchy (not needed any more) * Don't call GetRuntimeEvents unless we've processed a member.

As such all paths for the flags indicating a base call are dead code. As such the exception for base-calling an abstract class or a destructor cannot be reached, so remove the error codes for them. Also remove the error code for calling a finaliser directly as likewise impossible to express (calling another object's finaliser is separately blocked due to access). Contributes to #22470 22519 area-Microsoft.CSharp Consolidate overloads of checkUnsafe in Microsoft.CSharp One is only ever called by the other, so merge them into a single method and remove paths this rules out. This shows an assert using `ErrorCode.ERR_SizeofUnsafe` to be unnecessary and it was the only use of that code, so remove it. Contributes to #22470 22520 area-System.Linq Request: Consider displaying count in debugger display when known for System.Linq iterators "Today I was debugging an xUnit theory that accepted an `IEnumerable`. In my test data method, I was generating the enumerable via `Enumerable.Range`. When I looked at the enumerable in the debugger, it was stringified to `{System.Linq.RangeIterator}`. I needed to evaluate the enumerable via 'Results View' and count the number of elements displayed to find the count. Can we consider just displaying the count in the debugger display if we know it already? We can even consider adding more information for a few iterators, where there's not a risk of stringifying a really long collection or evaluating user-supplied functions. For example, we can show `Start = x, Count = y` in the debugger display for `Range` and `Element = ..., Count = x` for `Repeat`." 22525 area-Microsoft.CSharp Remove Microsoft.CSharp paths for collection initialization There's no way to express this to the dynamic binder (any use of `dynamic` in an initializer is turned into `Add` calls at the static compilation stage), so `BindMethodGroupToArgumentsCore` is only ever called with `bindingCollectionAdd` as false). Remove this parameter and those paths that depend on it being true. Entails the deletion of `ERR_BadArgTypesForCollectionAdd` and `ERR_InitializerAddHasParamModifiers`, contributes to #22470 22527 area-Infrastructure Project URL isn't meaningful Our packages all point to `http://dot.net` which isn't a very meaningful location. Instead, the packages should probably point to their proper GitHub repos, e.g. `https://github.com/dotnet/corefx`. 22528 area-Microsoft.CSharp RuntimeBinderException could provide a useful HelpLink Many causes of `RuntimeBinderException` being thrown are directly analogous to causes of compile-time errors when compiling C#. These errors all have some, often copious, information available about them on the web, and roslyn already has a mechanism for guiding developers to a Bing search, which could be easily piggy-backed on to provide a `HelpLink` that has a good chance of beating the results found by copy-pasting the error message into a search engine. 22529 area-Microsoft.CSharp Add HelpLink to RuntimeBinderException when error relates to C# error Closes #22528 22533 area-Microsoft.CSharp Remove two checks for EXPRFLAG values in Microsoft.CSharp that are never set * Remove checks for implicit this. We never have an implicit this within a dynamic expression (if an argument to an expression with implicit this has a dynamic argument, then the static binder has already selected the correct object or type argument), so don't check for it when checking static-ness (*stasis*? :wink:) is correct * Remove check for literal constant. Literal status is never set (and rather meaningless after static compilation), so remove branch depending on it. Entails removal of `ERR_LiteralDoubleCast`, contributes to #22470 22534 area-Microsoft.CSharp Microsoft.CSharp does not report CS1545 or CS1546 "If a type has property with parameters that is not its indexer property, then attempting to index it in C# will cause either CS1545 if it has both a getter and setter (""Property, indexer, or event 'XXX' is not supported by the language; try directly calling accessor methods 'get_XXX' or 'set_XXX'"") or CS1546 if it has only one of those (""Property, indexer, or event 'XXX' is not supported by the language; try directly calling accessor method 'get_XXX'""). If the same thing happens with dynamic code, it throws an exception equivalent to a less helpful (and slightly misleading) CS0570 with a message of ""'TheType' is not supported by the language"". There's code to report CS1545 or CS1546, but it fails to identify the situation when that code should be run." 22535 area-System.Net ClientWebSocket throws exception when connecting after abort "The [documentation ](https://msdn.microsoft.com/en-us/library/system.net.websockets.clientwebsocket.abort(v=vs.110).aspx) of `ClientWebSocket.Abort()` says: > Aborts the connection and cancels any pending IO operations. But after calling `Abort`, one can no longer connect with that ClientWebSocket. The following snippet throws an ObjectDisposedException (""Cannot access a disposed object""): ``` CancellationTokenSource src = new CancellationTokenSource(); ClientWebSocket socket = new ClientWebSocket(); socket.ConnectAsync(new Uri(""wss://echo.websocket.org""), src.Token).Wait(); socket.Abort(); socket.ConnectAsync(new Uri(""wss://echo.websocket.org""), src.Token).Wait(); ``` I understand that this exception is thrown when trying to reconnect after a `Dispose` call (since the documentation states that unmanaged resources are released), but why is it also thrown after `Abort`?" 22536 area-Microsoft.CSharp Constructor Using Dynamic Type Not Visible When Using InternalsVisibleTo "_From @adamrodger on July 23, 2017 16:35_ I have a class in `ClassLibrary1` like this: ```csharp [assembly: InternalsVisibleTo(""OtherLibrary"")] public class Foo { internal Foo(dynamic bar) { Console.WriteLine(bar.Bar); } } ``` And then in `OtherLibrary` I have a test: ```csharp [Fact] public void Test1() { dynamic bar = new { Bar = ""Success!"" }; Foo x = new Foo(bar); } ``` **Expected Result**: Running the test passes and ""Success!"" is written to the console **Actual Result**: ``` Microsoft.CSharp.RuntimeBinder.RuntimeBinderException : 'ClassLibrary1.Foo.Foo(object)' is inaccessible due to its protection level at CallSite.Target(Closure , CallSite , Type , Object ) at CallSite.Target(Closure , CallSite , Type , Object ) at OtherProject.UnitTest1.Test1() ``` If I change the constructor to take an explicitly typed object (e.g. pass a string directly) then the test passes. If I make the constructor public then the test also passes. It's only when `Foo` has an internal constructor with a `dynamic` argument. _Copied from original issue: dotnet/coreclr#12988_" 22537 area-Microsoft.CSharp "Remove most use of ""Bogus"" from Microsoft.CSharp and fix remaining" * Remove concept of bogus from types and most symbols. Since bogus types can't get as far as the dynamic binder, the only case where bogus can be true is when a non-indexer parametrized property, defined in a language where that is allowed, is encountered. In other cases computing bogosity involves recursive checks that always hit false. Give `PropertySymbol` a separate `Bogus` property to use where it could be set, and remove all other uses of `GetBogus` and similar. Entails removal of `ERR_BogusType`, contributes to #22470 * Identify indexer properties correctly in `AddPropertyToSymbolTable` `AddPropertyToSymbolTable` assumes any property with parameters is an indexer, which makes the subsequent check that only indexers can have parameters tautologous. Check `DefaultMemberAttribute` instead. * Remove `useMethInstead` from property symbols and consider always true. `useMethInstead` should be set in `AddPropertyToSymbolTable` when bogus is set, but is not. However, the only time it is looked for the only possible value is true as that is the only condition under which a symbol can be bogus, so remove it, and the path for it being false. This now means that `ErrorCode.ERR_BindToBogusProp1` or `ErrorCode.ERR_BindToBogusProp2` will be used when appropriate (contributes to #22470). Fixes #22534 * Tests for accessing non-indexer parameter properties * Remove bogus check within PredefinedMembers Predefined properties cannot be bogus. 22538 area-System.Data Increase code coverage from 70.8% to 74.9% on System.Data.Common.DataColumnMappingCollection Hi, I had some time so here are a few more unit tests. If you have any questions or comments, please let me know. Thanks, Michael 22539 area-System.Net add test variations for simulating sync operations over a nonblocking socket On non-Windows platforms, once non-blocking is turned on (either explicitly or by performing an async operation), we always stay in non-blocking mode. Therefore, any subsequent sync operation have to be simulated via async and explicit blocking. Add some test variations that cover this scenario. Also fix the Send timeout test to actually test for Send timeout. @stephentoub 22541 area-Microsoft.CSharp Remove some deadcode from Microsoft.CSharp's predefined members * Remove predefined methods the dynamic compiler never uses * Remove null-check from `GetMethod` and merge `GetOptionalMethod` into it. Predefined methods can't be unexpectedly missing if the code is running. * Don't look for setter for predefined property. The only example doesn't have one. * Change `LoadProperty` order to always load property first, ensuring method loads correctly immediately. * Remove error check from `GetProperty` as it cannot happen for only value it is ever called with. * Remove `ReportError` as the two overloads that called it are gone. Entails removal of `ERR_MissingPredefinedMember`, contributes to #22470 * Remove `PP_FIRST` Acts as a guard value, but starting from zero works just as well and without waste. * Remove `PM_FIRST` Acts as a guard, but 0 or `PM_COUNT` works as well without waste. 22542 area-System.Data "Test: System.Data.SqlClient.Tests.AmbientTransactionFailureTest/TestSqlException failed with ""System.ArgumentNullException""" Opened on behalf of @Jiayili1 The test `System.Data.SqlClient.Tests.AmbientTransactionFailureTest/TestSqlException(connectAction: Action`1 { Method = $BlockedFromReflection_4_851c0221 { Attributes = ReuseSlot, Assembly, HideBySig, C...` has failed.

In UWP get or set the current culture from/to Windows.ApplicationModel.Resources.Core.ResourceManager.Current.DefaultContext.Languages. This causes the current cultures global to the whole app. In the none-UWP app, the current cultures are tied to the running thread. Which means setting current culture will affect the current thread and is not global to the whole apps. The request here is, Allow a way for UWP apps to force the behavior of the none-UWP apps to have the current culture tied to the thread instead to be global to the whole app. Initial thoughts to support that uses a config switch the app can declare to force this new desired behavior. The other idea is to provide some new API to force this behavior but I think the API would have some serious problems. 22566 area-System.Data Adding SqlConnectionStringBuilder.Enlist to public method contract I added `SqlConnectionStringBuilder.Enlist` to public method contract, and also add more unit tests for `SqlConnectionStringBuilder.Enlist` 22567 area-System.IO Fix System.IO.FileSystem.Tests for UapAot Fixes: https://github.com/dotnet/corefx/issues/22544 22568 area-Infrastructure Ubuntu16.10 is EOL so remove it form our test queues cc @stephentoub @MattGal @danmosemsft 22569 area-System.Net Uri.ReCreateParts allocates a char[] that could be avoided Accessing a property like Uri.PathAndQuery not only allocates the resulting string, but also a char[] that's often larger than necessary and which is then used to create that resulting string. Whenever/wherever possible, it'd be good to avoid that allocation. As an example of the impact of this allocation, that one char[] array is currently showing up as ~14% of the memory allocated when making a simple get request with ManagedHandler. Related to https://github.com/dotnet/corefx/pull/16456 cc: @safern, @geoffkizer, @cipop 22570 area-System.Net Several improvements to ManagedHandler The main change is to switch how reading is done so that the core logic is handed back a line at a time to parse rather than having to parse byte-by-byte. I also separated classes out into their own files to make the solution a bit more manageable, and employed several others perf tweaks, like using a single empty response stream when possible, using Span instead of ArraySegment where possible, etc. For simple get requests, this improves throughput by 5-10%. cc: @geoffkizer 22571 area-System.Drawing Add Unix implementation for System.Drawing.Common "This PR adds a Unix implementation for System.Drawing.Common. This implementation has been taken from the mono codebase, and implements the majority of its image-processing and graphics functionality in a native library called ""libgdiplus"". This library is available on all of the Linux distributions we support, as well as macOS through homebrew. Up until the final commit, the code pulled into this repository is identical to the implementation in mono. The final commit makes a large change to the mono codebase due to its reliance on the DllMap feature, which is not supported in .NET Core. To fix this, I have removed all of the PInvoke declarations for GDI+ functions, and replaced them with manual function loading. Please see [this commit description](https://github.com/mellinoe/corefx/commit/48e96d5ac2e51a7a388aa5d066c9f516faa22e2d) for a more thorough explanation of the process. Functionally, the behavior should be identical to before my change, but the library loading mechanism will be more flexible and resilient. Currently, a large number of tests are disabled on Unix by this PR. A large chunk of the test failures are due to differences in argument validation or exception behavior, which can be fixed within the managed implementation. There is an unknown number of behavioral problems inherent to the libgdiplus implementation we are using, which will be much more problematic to solve. There will be a long process of understanding these behavioral differences as we go forward. The CI machines have been updated with the new ""libgdiplus"" dependency, so there should be no more blockers for merging this work. @qmfrederik @akoeplinger @marek-safar @stephentoub @stephentoub I'd appreciate any input on the function-loading approach I've taken; it is in the final commit.

If you force the socket into nonblocking mode (e.g. socket.Blocking = false; socket.blocking = true;) then the timeouts are as expected. 22588 area-System.Net Linux Sockets: fix timeout handling by forcing into nonblocking mode Fixes #22587 Currently, we can't reliably support send/receive timeouts because we can't distinguish between an EAGAIN caused by a nonblocking socket, and one caused by a timeout on a synchronous system call. Fix this by forcing us into AsyncContext mode when a timeout is set. This handles the timeout semantics correctly. @stephentoub 22589 area-System.Net Dns.GetHostEntryAsync is faulty on Windows "When calling `Dns.GetHostEntryAsync()` an `AggregateException` is always thrown with information of: > System.AggregateException was unhandled > Source=System.Private.CoreLib > InnerException: > HResult=-2147467259 > Message=Either the application has not called WSAStartup, or WSAStartup failed > NativeErrorCode=10093 > Source=System.Net.NameResolution > StackTrace: > at System.Net.Dns.HostResolutionEndHelper(IAsyncResult asyncResult) > at System.Net.Dns.EndGetHostEntry(IAsyncResult asyncResult) > at System.Net.Dns.<>c.b__15_1(IAsyncResult asyncResult) > at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) > It seems that the method does not correctly initialize Winsock through `WSAStartup()`.

This is necessary as RHEL 6 is super ancient w.r.t. the libraries that we depend on. So if we build on RHEL 7, which was our minimum supported distro, the binary will get dependencies on versions of some symbols that are not present on RHEL 6. As a result, to run dotnet core on RHEL 6, it has to be built on RHEL 6, which requires the corresponding docker to be created. RHEL 6 is NOT free, so we should create equivalent CentOS 6 docker instead. We already have CentoOS docker file available, which can be used as the starting point for the CentOS 6 one. 22622 area-System.Net Account for differences in WebSocket minimum buffer sizes between Core and Framework Client.WebSocketOptions.SetBuffer(...) has different validation between the .Net Core and Framework versions. The previous tests assumed that ClientWebSocket.Options.SetBuffer would accept a minimum buffer size of one, which is not the case in the Framework implementation. Unlike .Net core, the Framework expects a minimum size of 16 for the send buffer and 256 for the receive buffer. This meant that tests intended to pass a _valid_ minimum receive buffer size (of 1) and an _invalid_ minimum send buffer size (of 0) would trigger an exception with the wrong message, as the (accidentally) incorrect minimum receive buffer size of 1 failed validation. Additionally, the test would fail because of a slight difference in the name used for the internal buffer, and as such a conditional was added to ensure that the correct name is checked on each version.

For custom implementations of these types, it would be nice if there were *Async versions of these APIs. For example, an [implementation](https://github.com/onovotny/RSAKeyVaultProvider) that uses Azure Key Vault can do this asynchronously. I would propose these types be virtual, and if no inheritor overrides them, delegates to the synchronous version in the similar fashion that some of the IO Stream types do. Going forward, it would be nice then if the core framework used those asynchronous APIs when possible. This also allows other user implementations to take an `RSA` type and get the benefit of async if the inheritor chooses to implement a real async version. Sample idea: ```csharp public virtual Task SignDataAsync( byte[] data, HashAlgorithmName hashAlgorithm, RSASignaturePadding padding ) { return Task.FromResult(this.SignData(data, hashAlgorithm, padding)); } ``` 22638 area-System.Net Cannot get Header value back when it includes special chars.

This works well for 'static' counters (that get created early and live forever), but does not allow for counters that are specific to objects that come and go. For example. There may be a counter for the I/O operations for a request. Thus you would like a counter that gets created when request is received, update, and then destroyed when the request is complete. Adding a Dispose() method on EventCounter allows this. Thus the proposed API change is to add the Dispose method and make EventCounter IDisposeable ```c# public class EventCounter : *IDisposable* { public EventCounter(string name, EventSource eventSource) { } public void WriteMetric(float value) { } *public void Dispose() { }* } ``` I can be used like this ```c# request.ioCounter = new EventCounter(""I/O Operations: "" + request.url, logger); ..... counterForRequest.WriteMetric(ioSize); // Do this at the appropriate point. .... ``` And in the code that cleans up a request request.ioCounter.Dispose(); request.ioCounter =- null; **Dispose is an optional API**.

"cc @geoffkizer @stephentoub @karelz Implemented following the rules listed in [RFC 7616](https://tools.ietf.org/html/rfc7616). Verified the correctness of the implementation using a third party digest authentication validator [here](http://pernau.at/kd/sipdigest.php). The header field values are set as expected. While performing a real Http scenario test using httpbin, digest authentication returns Unauthorized on .NET Core. Note that this bug reproes even when not using ManagedHandler. Whereas, on full framework the httpbin test with digest auth passes. I'm not sure what's wrong, used the following code to test. @CIPop Is Digest authentication expected to work with .NET Core HttpClient? ```c# using (HttpClientHandler handler = new HttpClientHandler()) { handler.Credentials = new NetworkCredential(""user"", ""passwd""); using (HttpClient client = new HttpClient(handler)) { using (HttpResponseMessage m = client.GetAsync(""http://httpbin.org/digest-auth/auth/user/passwd/MD5"").Result) Console.WriteLine(m.StatusCode); } } ``` Update: 1. Figured out httpbin test failure, httpbin expects the cookie header to also be sent during digest auth to pass digest authentication. By hacking my test to always send a cookie header with the digest auth, passed the httpbin test. This issue is already reported to httpbin, and was closed as by design. https://github.com/kennethreitz/httpbin/issues/124 2. Tested the following scenarios: - qop: auth, algorithm: MD5 - qop: auth-int, algorithm: MD5 - qop: auth, algorithm: MD5-sess - qop: auth-int, algorithm: MD5-sess - qop: auth, algorithm: SHA-256 - qop: auth-int, algorithm: SHA-256 - qop: auth, algorithm: SHA-256-sess - qop: auth-int, algorithm: SHA-256-sess - Multiple requests with same username, password - updates nonce count Pending: 1.

While the two cases could be distinguished, just rewording to cover both cases would probably suffice. 22696 area-Microsoft.CSharp M.CSharp: Improve error handling with CSharpInvokeConstructorBinder * Better message for ctor called by non-type. `TypeArgumentRequiredForStaticCall` can be used for constructor calls as well as static type calls, so reword to cover that case. Fixes #22695 * Refactor `GetTypeForErrorMetaObject` We only need to extract the first item in `args` in one case, so pass the array rather than that first element. Replace `as` used just as test with `is`. In `action is CSharpInvokeConstructorBinder` branch, first argument is guaranteed to be a Type, or there would have been an `ArgumentException` earlier, so no need to guard against it being otherwise. 22697 area-System.Net Random exceptions with System.Net.Http.WinHttpHandler _From @hanabi1224 on July 27, 2017 18:34_ It randomly(at very low chance) throws 'An item with the same key has already been added.' when SendAsync being called, and same issue never happen after removing WinHttpHandler Package version: 4.3.1 .Net version: 4.6.2 OS: Azure guest OS 5-* Http version: 2.0 _Copied from original issue: dotnet/coreclr#13086_ 22700 area-System.Net ManagedHandler: Failing AllowAutoRedirect_True_ValidateNewMethodUsedOnRedirection test Discovered while working on PR #22702.

In the past, we would let the WinRT layer handle auto redirection logic. However, due to #9003, the cookies were getting lost on 3xx responses since the .NET layer didn't see them. So, this PR implements the redirection ourselves. One important part of redirection is that we need to drop credentials. The WinRT layer did this for us. However, we are unable to use a single WinRT HttpBaseProtocolFilter object since we need to remove the credential after the first redirect. So, we need to maintain a second filter that uses no credentials and keep it in sync regarding all the other properties of the primary filter. With this PR, the behavior of other aspects (such as controlling max number of redirects, etc.) now matches .NET Framework. So, some tests were adjusted to remove the UAP specific behavior checks.

Create only if it's used. * Remove unreachable branch. We're in a branch for `type.fundType()` being `FT_PTR` and comparing that with something that will always be `FT_REF`, so that branch is unreachable. * Remove error branch in `CreateZeroInit` Could only happen if called with a type like void that doesn't have a fundamental type, but no callsite attempts this.

In the past, we would let the WinRT layer handle auto redirection logic. However, due to #9003, the cookies were getting lost on 3xx responses since the .NET layer didn't see them. So, this PR implements the redirection ourselves. One important part of redirection is that we need to drop credentials. The WinRT layer did this for us. However, we are unable to use a single WinRT HttpBaseProtocolFilter object since we need to remove the credential after the first redirect. So, we need to maintain a second filter that uses no credentials and keep it in sync regarding all the other properties of the primary filter. With this PR, the behavior of other aspects (such as controlling max number of redirects, etc.) now matches .NET Framework. So, some tests were adjusted to remove the UAP specific behavior checks. Fixes #9003 Fixes #22191 22760 area-Microsoft.CSharp Simplify symbol factory in Microsoft.CSharp down to a single type. * Remove `MiscSymFactory`, moving functionality into `SymFactory` No benefit to the split. * Remove `SymFactoryBase` Only has one derived type, so move its functionality into that. * Rename some locals and members local to `SymFactory` 22761 area-Microsoft.CSharp Refactor init methods into ctors in Microsoft.CSharp Move `BSYMMGR` init methods into ctor Move `TypeManager` init method into ctor Remove no-op calls to `TypeManager.InitType` 22762 area-Microsoft.CSharp Tidy some nullable-handling in Microsoft.CSharp * Remove paths for `Nullable` not having `Value` property or ctor Will only fail if `Nullable` is so broken that we can't run anyway. * Fix `NullableType.GetAts` calls Remove unused parameter, move all implementation into check for memoised result, and remove paths for it returning null, which can't happen. * Remove unnecessary looping to cast `T??` 22763 area-System.Text Fix last character check in TextEncoder.EncodeIntoBuffer Fixes #22755 22764 area-System.Net Socket.BeginAccept does not allow socket reuse If you call socket.Disconnect(true) and then try to BeginAccept into that socket, you get InvalidOperationException. If you use SocketAsyncEventArgs to do the Accept, it succeeds. This is Windows-only and not a common scenario at all, but I found it while adding tests so I thought we should at least track it. 22765 area-System.Net Linux sockets: async connect on already connected socket does not throw If you do a ConnectAsync on an already connected socket, no exception is thrown. Synchronous Connect correctly throws a SocketException with errorcode SocketError.IsConnected. 22766 area-System.Net refactor some Socket test code into SocketTestHelper, and modify some existing tests to use this Refactor the existing logic in SendReceive.cs for abstracting across sync/APM/Task/etc and generalize it. Also, update existing Accept and Connect tests to use this. Some existing Accept/Connect tests that are specific to SocketAsyncEventArgs are moved to SocketAsyncEventArgsTests.cs.

Say for example we have a binder from: ```C# BinaryOperationBinder binder = Microsoft.CSharp.RuntimeBinder.Binder.BinaryOperation( CSharpBinderFlags.None, ExpressionType.Add, GetType(), new[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null), CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null)} ) as BinaryOperationBinder; ``` Then if called with: ```C# binder.FallbackBinaryOperation(null, null); ``` We get a `NullReferenceException` rather than an `ArgumentNullException`, and if called with: ```C# binder.FallbackBinaryOperation( new DynamicMetaObject(Expression.Parameter(typeof(object)), BindingRestrictions.Empty), new DynamicMetaObject(Expression.Parameter(typeof(object)), BindingRestrictions.Empty)) ``` We get a `RuntimeBinderInternalCompilerException` rather than an `ArgumentException` or any other exception that reflects the issue.

On short strings and only two char arrays, `String.IndexOfAny` is significantly slower than a hard-coded version, and on x86 (non-RyuJIT) even slower than a hand-written naive implementation where there is no matches.

A clean does not clear it away, but manually deleting the bin folder lets the project run successfully. Most of all, I'd like to feel less helpless / have the tools or knowledge to work out why this is happening by a logical process of elimination / deduction. I've been using and trying to find a way to get us on board the .NET Core train for quite a while. This is our first production project and is utilising some new .NET Core / .NET Standard libraries we have for some parts, and .NET Framework for others. It's been a very difficult experience so far, specifically any time .NET Framework assemblies are referencing netstandard ones. Through bashing against this kind of error for several weeks, I am piecing together facts and workarounds for NuGet versioning, redirects, reference assemblies, type forwarding, build file flags and a myriad of other nuggets. However, my knowledge is still evidently full of gaps. Is there a single place - or even a recommended set of places - where I can learn everything I need to know to have a project set up in this way? The knowledge set required to diagnose build and runtime errors in this kind of scenario so far seems huge, but I/we need to build this expertise internally.

Exposing System.Runtime.WindowsRuntime would enable us to perform many query and validation scenarios on hardware devices. 22790 area-System.Runtime A mechanism for specifying alignment on a field or struct should be supported. "### Rationale In certain high performance or specialized data structures/algorithms, it is desirable to enforce an alignment for structs, fields, or locals. Today, CoreFX provides several specialized data structures for which the runtime either has special alignment handling (`System.Numerics.Vector`) or for which they have some specialized padding (https://github.com/dotnet/corefx/pull/22724). As such, the framework/runtime should provide a mechanism for encforcing a specified alignment for structs and fields. Locals should also be included if that is feasible (I'm not sure if that is readily possible today given that attributes cannot be specified on locals). ### Additional Thoughts It might be worthwhile to additionally expose this on the existing `StructLayoutAttribute` as an `Alignment` property. An alignment of `0` should be treated as ""Automatic"" (the current behavior of letting the runtime decide alignment). A mechanism for aligning to the cache would be ideal (https://github.com/dotnet/corefx/pull/22724#issuecomment-319075196). This could perhaps be a special value that would otherwise be invalid (such as `Alignment=-1`). Other special alignments could also be allowed in a similar manner. If a field specifies an alignment less than that of the struct, it should be aligned to the alignment of the struct. For example, if you do `Alignment=8` on a `Vector4` (which has an `Alignment=16`), the field should be treated as `Alignment=16`. [Design Decision] If a struct specifies an alignment less than that of its first field it should either: A. Align the struct as specified and add the appropriate padding so that the first field is also aligned as specified -or- B. Align the struct as per the requirements of the first field [EDIT] Make reference to the PR a link by @karelz" 22791 area-System.Diagnostics BasicEventSourceTests.TestEventCounter.Test_Write_Metric_EventListener fails on UWP.

In the former case an `int` is fine, but in the latter it would be great to allow `int64` to allow offsets beyond the 2Gb mark in large files. The winsock API accepts an int64 too: https://github.com/dotnet/corefx/blob/master/src/Common/src/Interop/Windows/Winsock/Interop.WinsockAsync.cs#L70 and https://msdn.microsoft.com/en-us/library/windows/desktop/ms740570(v=vs.85).aspx In case the offset means an offset in a byte buffer, there is validation in place already to check that the offset is not out of bounds. Perhaps it is enough to make the field into an `int64` and add another constructor overload taking a filename and `int64` offset. 22798 area-System.Net WebRequest.DefaultWebProxy: Set doesn't work without a previous Get Iteration1: https://github.com/dotnet/corefx/pull/22720. Added test case as per comments in iteration1. Unless we do an unnecessary Get() on WebRequest.DefaultWebProxy, any Set() done will not be honored. This is especially a problem on Linux, where DefaultWebProxy throws PlatformNotSupportedException(). This in turn breaks libraries like WindowsAzure.Storage which fail unless the Get() is called first and then WebRequest.DefaultWebProxy is set to null.

Get the HttpListenerContext: `Task contextTask = _listener.GetContextAsync();`. 2. Using a HttpClient to Send a POST request to the specified Uri HttpListener listening on: `Task clientTask = client.PostAsync(_factory.ListeningUrl, ""hello"");`. 3. Get the `HttpListenerRequest request` from HttpListenerContext.Request, and do some testings and validations. 4. Use `context.Response.Close();` to finish the operation. The `public async Task GetRequest(bool chunked)` in `GetContextHelper.cs` causes problem because: For the `PostAsync` operation, the returned Task object will complete after the whole response (including content) is read. We use `context.Response.Close()` to send the response to the client by closing the response. Above procedures worked well on netcore. However, on ILC, we need to explicitly `await clientTask` to finish. (First few runs are working, but if run the test case for many times, i.e a test case has many inline data, it will hang.)

Hi, I'm in the middle of trying to clean up the `SortedSet` code. Over [here](https://github.com/jamesqo/corefx/blob/9f892eb60e68916d24670190ecc070eb22b6973e/src/System.Collections/src/System/Collections/Generic/SortedSet.cs#L927-L989), in both `UnionWith` and `IntersectWith`, there is a huge 60-line block of code that checks if the other enumerable is a `SortedSet` and if so does a mergesort on it, all inline. I'm wondering why this optimization was added in the first place: is it a common case to call `UnionWith` with a `SortedSet`? And were there perf problems with a naive implementation like ```cs foreach (T item in other) { Add(item); } ``` ? I checked the earliest version of `SortedSet.cs` on the [referencesource repo](https://github.com/Microsoft/referencesource/blob/9da503f9ef21e8d1f2905c78d4e3e5cbb3d6f85a/System/compmod/system/collections/generic/sortedset.cs#L1005), and the optimization was still there.

For the most part, the library can be easily retargeted, with a few small caveats. I'm filing this issue to document the things that will need to change for us to target .NET Core 2.0. * Work around missing types in other .NET Core 2.0 assemblies. Almost everything that has been added is isolated to the System.Drawing.Common assembly, but there are a few types that were added or modified elsewhere: * `KnownColor` is now public in System.Drawing.Primitives. * `Color` exposes several previously-private members as public. * `InvalidEnumArgumentException` was exposed publically, and is thrown by System.Drawing.Common. * `SystemDrawingSection` was added to ConfigurationManager. * Testing plan. We can test the .NET Core 2.0 configuration against the current-built runtime, but we won't be able to do that easily if we also add a .NET Core 2.1 configuration. This is because the test project will just select the ""most applicable version"", which would be .NET Core 2.1, if both existed. We can potentially work around this limitation, but it would be messy. For the time being, let's just support the .NET Core 2.0 configuration when testing. I plan to tackle the code changes in this way: * `KnownColor`: Add an internal copy of KnownColor into System.Drawing.Common. This type is an implementation detail anyways -- it's identity doesn't leak out of the library. We should share the source code with System.Drawing.Primitives to avoid duplication. * `Color`: Access the private members through reflection. These are already implemented in .NET Core 2.0, they just aren't public. The only change I made for .NET Core 2.1 was changing the accessibility. * `InvalidEnumArgumentException`: Add an internal version of this exception to be thrown instead. The tests will need to be modified to allow for the base-type to be thrown, though, because this exception will not have the same identity as the one from System.ComponentModel.Primitives. * `SystemDrawingSection`: Stop reading from ConfigurationManager for these settings. In both cases, there is already reasonable behavior if no configuration value is read." 22833 area-System.Drawing Change System.Drawing.Common's target to netcoreapp2.0 "There are two parts to this PR: 1.

Recently, the design document for `.NET Platform Dependent Intrinsics` was published (https://github.com/dotnet/designs/blob/master/accepted/platform-intrinsics.md). One of the things that still needs to be determined is the exact ""look and feel"" of the exposed APIs. Given the requirements put forth in the design doc, I explored what exposing the x86 SSE intrinsics might look like. I believe we need a minimum of 3 attributes: * `Intrinsic` identifies a method as exposing an intrinsic * It might be worthwhile letting the constructor take a set of strings that indicates alternative aliases for the function * `Literal` identifiers a parameter that is required to be a literal (there are a few instructions that require this) * Ideally this would cause `modreq literal` to be emitted and would have compiler supports * This could probably go in `System.Runtime.CompilerServices` rather than `S.R.CS.Intrinsics` * `Alignment` enforces an alignment for a struct. * I have a separate proposal for such an attribute here https://github.com/dotnet/corefx/issues/22790. * This can probably go in `System.Runtime.InteropServices` where it makes more sense For SSE, there are 4 different register sizes: 64, 128, 256, and 512. * These are separate rather than a generic 'Vector` type so that the user can explicitly dictate which register size they are using (and therefore also control clearing of upper bits, etc) * These expose an `IsSupported` property so the user can determine whether the CPU supports that register size (for example, this can indicate support for https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_mm256_cvtss&expand=1809). * These structs are currently generic and do not expose the underlying fields (which should not be accessed directly anyways) * It might be worthwhile seeing if we can enforce these to be ""stack only"". Ideally users would always guarantee they have a software fallback and create their types as such as well. That is, they would never declare `Simd128` as a field, and instead would declare `float x, y, z, w` and would explicitly call `Load` and `Store` to get a `Simd128` The SSE static class exposes all the instructions supported by the SSE CPUID bit flag: * Methods which do not have a software implementation are marked as 'extern' * The runtime should throw a PNSE if IsSupported is false * This forces any consumers (such as AOT compilers) to understand the method * Most of the method names can be differentiated by overload * For some method names, we have to append 'Scalar', since the packed and scalar forms both take `Simd128` and just treat the parameter differently. * Some of the names may not be ideal, I just chose something that made some sense ```C# namespace System.Runtime.CompilerServices.Intrinsics { [AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = false)] internal sealed class IntrinsicAttribute : Attribute { // Indicates that a method is an intrinsic // Optional.

My collection implements IEnumerable and therefore it returns my own thread-safe Enumerator. The enumerator uses the ReaderWriterLockSlim-Class and enters the READ-lock while retrieving it over GetEnumerator() and exits the lock when the Dispose()-Method is invoked. This works normally fine - but not with the DataContractSerializer. When the DataContractSerializer serializes my collection it retrieves the enumerator but after serializing it doesn't invoke the Dispose()-Method. As a result my other threads can't change the Collection any more. I know, that I'm writing this issue at a the wrong project (.NET-Core) but the C#-Code here is very similar to the big framework and I hope somebody could help me.

"Late-bound invokes through Reflection wrap exceptions thrown by the target in a `TargetInvocationException`. In many cases, this behavior is not desired and counter-productive. For those who want the actual exception, it requires unwrapping the `TargetInvocationException` to rethrow the inner exception and to retrieve the full call stack. The fact that every exception is ""caught"" hampers the normal debugging experience. It'd be useful to have a way to opt out of this wrapping. We can do this without adding lots of new overloads by adding a new member to the `BindingFlags` enum: `BindingFlag.DoNotWrapExceptions`. Setting this bit would disable the wrapping behavior. Here is a fiddle of the code sample included below: https://dotnetfiddle.net/o9qUht ```C# public class Program { public static void Main() { try { var bf = BindingFlags.Static | BindingFlags.Public | BindingFlags.InvokeMethod; bf |= BindingFlags.DoNotWrapExceptions; typeof(Program).InvokeMember(""LateBoundTarget"", bf, null, null, null); } catch(TargetInvocationException e) { Console.WriteLine(""fail""); } catch(InvalidOperationException e) { Console.WriteLine(""success""); } } public static void LateBoundTarget() { throw new InvalidOperationException(); } } ``` ### Apis that would be affected: ```c# public static class Activator { public static object CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, object[] args, CultureInfo culture); public static object CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, object[] args, CultureInfo culture, object[] activationAttributes); } public class Type { public object InvokeMember(string name, BindingFlags invokeAttr, Binder binder, object target, object[] args); public object InvokeMember(string name, BindingFlags invokeAttr, Binder binder, object target, object[] args, CultureInfo culture); public abstract object InvokeMember(string name, BindingFlags invokeAttr, Binder binder, object target, object[] args, ParameterModifier[] modifiers, CultureInfo culture, string[] namedParameters); } public class Assembly { public virtual object CreateInstance(string typeName, bool ignoreCase, BindingFlags bindingAttr, Binder binder, object[] args, CultureInfo culture, object[] activationAttributes); } public abstract class ConstructorInfo : MethodBase { public abstract object Invoke(BindingFlags invokeAttr, Binder binder, object[] parameters, CultureInfo culture); } public abstract class MethodBase : MemberInfo { public abstract object Invoke(object obj, BindingFlags invokeAttr, Binder binder, object[] parameters, CultureInfo culture); } public abstract class PropertyInfo : MemberInfo { public abstract object GetValue(object obj, BindingFlags invokeAttr, Binder binder, object[] index, CultureInfo culture); public abstract void SetValue(object obj, object value, BindingFlags invokeAttr, Binder binder, object[] index, CultureInfo culture); } ``` [EDIT] Added C# syntax highlight by @karelz" 22867 area-System.Net Add basic EventSource tracing to ManagedHandler cc: @geoffkizer 22869 area-System.Drawing Add nuget package configuration for System.Drawing.Common This adds a nuget package for System.Drawing.Common, which can be referenced in any .NET Core 2.0 or .NET Framework project.

I'd like to lift that restriction and allow Type.MakeGenericType to further instantiate partially instantiated types. For example, given a `type` representing `Foo` where `T0` represents the first generic type parameter then the type `Foo` could be constructed by calling `type.MakeGenericType(typeof(string))`. Here is a fiddle of a slightly more complicated example which is copied below: https://dotnetfiddle.net/HYGMv9. A few ""food for thought"" cases: * If fewer types are supplied to `MakeGenericType` then the missing generic parameters are assumed to be the existing substitutions. Thus `type.MakeGenericType(new Type[] { })` would always succeed and return `type`. * `MakeGenericType` may accept fewer than or an equal number of types than `GenericTypeParameters.Length` but never more. * If all types have been substituted then `type.MakeGenericType(...)` will succeed (if an equal or fewer number of types than there are generic parameters are supplied) and return `type` * If no type parameters exist for a given substitution than that substitution is ignored. * `null` can be passed as a substitution argument to `MakeGenericType` if there no long exist any generic parameters which would be substituted for the position `null` occupies. * Although type parameters from other types can be used to instantiate a type only the type parameters for the type be instantiated are substituted. ``` C# using System; public class Foo { } public class Program { public static void Main() { var type = typeof(Foo<,,>); var genericArguments = type.GetGenericArguments(); var T0 = genericArguments[0]; var T1 = genericArguments[1]; var T2 = genericArguments[2]; var type_Int_T2_T1 = type.MakeGenericType(typeof(int), T2, T1); var type_Int_T1_Short = type.MakeGenericType(typeof(int), T0, typeof(short)); // Currently throws; Wish for it to succeed if (type_Int_T1_Short == type_Int_T2_T1.MakeGenericType( null, // T0 replacement => typeof(int) typeof(short), // T1 replacement T0) // T2 replacement ) Console.WriteLine(""success""); } }" 22871 area-System.Data SqlConnection.WorkstationId is null "Case 1: ``` var conn = new SqlConnection(@""Server=X;Database=master;User Id=Y;Password=Z""); Console.WriteLine(conn.WorkstationId); Console.WriteLine(Environment.MachineName); ``` in .NET 4.6 and mono it prints: > EGORBOPC > EGORBOPC in .NET Core it prints > (null) > EGORBOPC Case 2: ``` var conn = new SqlConnection(@""Server=X;Database=master;User Id=Y;Password=Z;Workstation Id=Desktop""); conn.Dispose(); Console.WriteLine(conn.WorkstationId); Console.WriteLine(Environment.MachineName); ``` in .NET 4.6 and mono it prints: > EGORBOPC > EGORBOPC in .NET Core it prints > """" (empty string) > EGORBOPC Windows 10 x86/64" 22872 area-System.Net Remove char[] allocation from Uri.HexEscape cc: @cipop, @davidsh 22873 area-System.Net Remove UriShim from HttpClient - Uri's members are now back in core; it can just use those directly. - Rather than calling HexEscape per character, which allocates a string per character, we can just encode directly to the StringBuilder. cc: @davidsh, @cipop, @geoffkizer, @Priya91 22874 area-System.IO Expand Deflate64 WindowSize The WindowSize being used in the old managed deflate implementation that I modified to decompress Deflate64 is too small. Deflate64 can have lengths up to 64kb as well as distances up to 64kb when doing lookback. In my initial implementation I disregarded the increased length, allowing potentially 64kb of data to be written to an outputwindow that only has as little as 258 bytes of open space. This causes the previously inflated yet-to-be-flushed data to be overwritten, causing invalid output. The fix is simple: increase the WindowSize to fit the new length/distance maximums. Becuase of the way our managed Deflate implementation is written, it's not possible to simply flush the OutputWindow after already determining the lookback without a large rewrite, so I opted for the increased WindowSize solution instead. Testing is unfortunately not simple because it's rare that a file will need such a high length/distance and we do not have a Deflate64 deflater so we have to rely on other programs for generating test input. I've got a file that allows reproduction of the failure, but it's 3gb and doesn't experience data loss until a little under the 1gb mark. Because of the large size of the test file, I've left it out. I also took the chance to cleanup the s_extraLengthBits field. Currently, we attempt to read extra bits from input when given an invalid symbol for determining length. By shortening the arrays to only valid values, we instead throw an InvalidDataException early. cc: @stephentoub 22875 area-System.Data Removed SNIMarsManager, and modified TdsParserStateObjectManaged so that it manages its own SNIMarsConnection if MARS is enabled.

One test (see https://github.com/dotnet/wcf/issues/2140) started failing on UAP. The issue is that the `HttpClientHandler` did not correctly set the associated `CookieContainer`. I did some investigation. To me, the bug seems to be in [`CookieTokenizer.FindNext`](https://github.com/dotnet/corefx/blob/e30fdc38e60f6fa2ed8e7e103d1f8c44655438cd/src/System.Net.Http/src/uap/System/Net/cookie.cs#L1264).

The above code probably should be, ```c# if (!Eof) { switch (m_tokenStream[m_index]) { case ';': token = CookieToken.EndToken; break; case '=': token = CookieToken.Equals; break; default: m_cookieLength = m_index - m_cookieStartIndex; token = CookieToken.EndCookie; break; } ++m_index; } if (Eof) // <--- Change here { m_cookieLength = m_index - m_cookieStartIndex; } ``` 22879 area-System.Data SqlConnection doesn't support empty values "``` var cn = new SqlConnection(""Timeout=""); Console.WriteLine(cn.ConnectionTimeout); ``` .NET 4.6 (and mono) prints: > 15 .NET Core: > System.ArgumentNullException: 'Value cannot be null.'

When Task/Task were initially introduced, we went back and forth on whether they should implement IObservable. The remnants of this are even still visible in the desktop code, e.g. http://referencesource.microsoft.com/#mscorlib/system/threading/Tasks/Future.cs,75 http://referencesource.microsoft.com/#mscorlib/system/threading/Tasks/Future.cs,1598 If I remember correctly (and I might not), the reason we eventually didn't implement it was for layering concerns at the time, but given that both Task and IObservable are in corelib on all platforms, and in System.Runtime, I don't think there are any such layering concerns remaining. The main benefit to implementing these interfaces is that then combinators for IObservable would then also work for Task, e.g. making it easier to stream together the results from arbitrary numbers of async operations. This would raise the question of whether a Task would also implement an IAsyncEnumerable if/when such an interface exists, and if not, why it would implement IObservable. There's also the question of whether both `Task` and `Task` would implement the interface, and if so, what would the type `T` be in `IObservable`, e.g. ```C# public class Task : Task, IObservable { ... } public class Task : IObservable { ... } ``` or ```C# public class Task : Task, IObservable> { ... } public class Task : IObservable { ... } ``` or ```C# public class Task : Task, IObservable { ... } public class Task : IObservable { ... } ``` or ```C# public class Task : Task, IObservable { ... } public class Task { ... } ``` with the oddity compounded by `Task` implementing both the `IObservable` interface it implements and the `IObservable` its base Task implements, if the latter does so. 22892 area-System.Data Add initial tests to System.Data.DataSetExtensions Integrated new tests as well as existing tests from Mono.

Fix #22877 22940 area-System.Runtime API Proposal: Add Intel hardware intrinsic functions and namespace "This proposal adds intrinsics that allow programmers to use managed code (C#) to leverage Intel® SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA, LZCNT, POPCNT, BMI1/2, PCLMULQDQ, and AES instructions. ## Rationale and Proposed API ### Vector Types Currently, .NET provides `System.Numerics.Vector` and related intrinsic functions as a cross-platform SIMD interface that automatically matches proper hardware support at JIT-compile time (e.g. `Vector` is size of 128-bit on SSE2 machines or 256-bit on AVX2 machines). However, there is no way to simultaneously use different size `Vector`, which limits the flexibility of SIMD intrinsics. For example, on AVX2 machines, XMM registers are not accessible from `Vector`, but certain instructions have to work on XMM registers (i.e. SSE4.2). Consequently, this proposal introduces `Vector128` and `Vector256` in a new namespace `System.Runtime.Intrinsics` ```csharp // Types.cs namespace System.Runtime.Intrinsics { // 128 bit types [StructLayout(LayoutKind.Sequential, Size = 16)] public struct Vector128 where T : struct {} // 256 bit types [StructLayout(LayoutKind.Sequential, Size = 32)] public struct Vector256 where T : struct {} } ``` This namespace is platform agnostic, and other hardware could provide intrinsics that operate over them. For instance, `Vector128` could be implemented as an abstraction of XMM registers on SSE capable processor or as an abstraction of Q registers on NEON capable processors. Meanwhile, other types may be added in the future to support newer SIMD architectures (i.e. adding 512-bit vector and mask vector types for AVX-512). In addition, this namespace would contain conversion functions between the existing SIMD type (`Vector`) and new `Vector128` and `Vector256` types, which enable legacy SIMD programs that use `Vector` to be further optimized for specific hardware. ### Intrinsic Functions The current design of `System.Numerics.Vector` abstracts away the specifics of processor details. While this approach works well in many cases, developers may not be able to take full advantage of the underlying hardware. Intrinsic functions allow developers to access full capability of processors on which their programs run. One of the design goals of intrinsics APIs is to provide one-to-one correspondence to [Intel C/C++ intrinsics](https://software.intel.com/sites/landingpage/IntrinsicsGuide/). That way, programmers already familiar with C/C++ intrinsics can easily leverage their existing skills. Another advantage of this approach is that we leverage the existing body of documentation and sample code written for C/C++ instrinsics. Intrinsic functions that manipulate `Vector128/256` will be placed in a platform-specific namespace `System.Runtime.Intrinsics.X86`. Intrinsic APIs will be separated to several static classes based-on the instruction sets they belong to. ```csharp // Avx.cs namespace System.Runtime.Intrinsics.X86 { public static class Avx { public static bool IsSupported {get;} // __m256 _mm256_add_ps (__m256 a, __m256 b) [Intrinsic] public static Vector256 Add(Vector256 left, Vector256 right) { throw new NotImplementedException(); } // __m256d _mm256_add_pd (__m256d a, __m256d b) [Intrinsic] public static Vector256 Add(Vector256 left, Vector256 right) { throw new NotImplementedException(); } // __m256 _mm256_addsub_ps (__m256 a, __m256 b) [Intrinsic] public static Vector256 AddSubtract(Vector256 left, Vector256 right) { throw new NotImplementedException(); } // __m256d _mm256_addsub_pd (__m256d a, __m256d b) [Intrinsic] public static Vector256 AddSubtract(Vector256 left, Vector256 right) { throw new NotImplementedException(); } ...... } } ``` Some of intrinsics benefit from C# generic and get simpler APIs: ```csharp // Sse2.cs namespace System.Runtime.Intrinsics.X86 { public static class Sse { public static bool IsSupported {get;} // __m128 _mm_castpd_ps (__m128d a) // __m128i _mm_castpd_si128 (__m128d a) // __m128d _mm_castps_pd (__m128 a) // __m128i _mm_castps_si128 (__m128 a) // __m128d _mm_castsi128_pd (__m128i a) // __m128 _mm_castsi128_ps (__m128i a) [Intrinsic] public static Vector128 StaticCast(Vector128 value) where T : struct where U : struct { throw new NotImplementedException(); } ...... } } ``` Each instruction set class contains an `IsSupported` property which stands for whether the underlying hardware supports the instruction set. Programmers use these properties to ensure that their code can run on any hardware via platform-specific code path. For JIT compilation, the results of capability checking are JIT time constants, so dead code path for the current platform will be eliminated by JIT compiler (conditional constant propagation). For AOT compilation, compiler/runtime executes the CPUID checking to identify corresponding instruction sets. Additionally, the intrinsics do not provide software fallback and calling the intrinsics on machines that has no corresponding instruction sets will cause `PlatformNotSupportedException` at runtime. Consequently, we always recommend developers to provide software fallback to remain the program portable. Common pattern of platform-specific code path and software fallback looks like below. ```csharp if (Avx2.IsSupported) { // The AVX/AVX2 optimizing implementation for Haswell or above CPUs } else if (Sse41.IsSupported) { // The SSE optimizing implementation for older CPUs } ...... else { // Scalar or software-fallback implementation } ``` The scope of this API proposal is not limited to SIMD (vector) intrinsics, but also includes scalar intrinsics that operate over scalar types (e.g. int, short, long, or float, etc.) from the instruction sets mentioned above. As an example, the following code segment shows `Crc32` intrinsic functions from `Sse42` class. ```csharp // Sse42.cs namespace System.Runtime.Intrinsics.X86 { public static class Sse42 { public static bool IsSupported {get;} // unsigned int _mm_crc32_u8 (unsigned int crc, unsigned char v) [Intrinsic] public static uint Crc32(uint crc, byte data) { throw new NotImplementedException(); } // unsigned int _mm_crc32_u16 (unsigned int crc, unsigned short v) [Intrinsic] public static uint Crc32(uint crc, ushort data) { throw new NotImplementedException(); } // unsigned int _mm_crc32_u32 (unsigned int crc, unsigned int v) [Intrinsic] public static uint Crc32(uint crc, uint data) { throw new NotImplementedException(); } // unsigned __int64 _mm_crc32_u64 (unsigned __int64 crc, unsigned __int64 v) [Intrinsic] public static ulong Crc32(ulong crc, ulong data) { throw new NotImplementedException(); } ...... } } ``` ### Intended Audience The intrinsics APIs bring the power and flexibility of accessing hardware instructions directly from C# programs. However, this power and flexibility means that developers have to be cognizant of how these APIs are used. In addition to ensuring that their program logic is correct, developers must also ensure that the use of underlying intrinsic APIs are valid in the context of their operations. For example, developers who use certain hardware intrinsics should be aware of their data alignment requirements. Both aligned and unaligned memory load and store intrinsics are provided, and if aligned loads and stores are desired, developers must ensure that the data are aligned appropriately. The following code snippet shows the different flavors of load and store intrinsics proposed: ```csharp // Avx.cs namespace System.Runtime.Intrinsics.X86 { public static class Avx { ...... // __m256i _mm256_loadu_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 Load(sbyte* address) { throw new NotImplementedException(); } // __m256i _mm256_loadu_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 Load(byte* address) { throw new NotImplementedException(); } ...... [Intrinsic] public static Vector256 Load(ref T vector) where T : struct { throw new NotImplementedException(); } // __m256i _mm256_load_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 LoadAligned(sbyte* address) { throw new NotImplementedException(); } // __m256i _mm256_load_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 LoadAligned(byte* address) { throw new NotImplementedException(); } ...... // __m256i _mm256_lddqu_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 LoadDqu(sbyte* address) { throw new NotImplementedException(); } // __m256i _mm256_lddqu_si256 (__m256i const * mem_addr) [Intrinsic] public static unsafe Vector256 LoadDqu(byte* address) { throw new NotImplementedException(); } ...... // void _mm256_storeu_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void Store(sbyte* address, Vector256 source) { throw new NotImplementedException(); } // void _mm256_storeu_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void Store(byte* address, Vector256 source) { throw new NotImplementedException(); } ...... public static void Store(ref T vector, Vector256 source) where T : struct { throw new NotImplementedException(); } // void _mm256_store_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void StoreAligned(sbyte* address, Vector256 source) { throw new NotImplementedException(); } // void _mm256_store_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void StoreAligned(byte* address, Vector256 source) { throw new NotImplementedException(); } ...... // void _mm256_stream_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void StoreAlignedNonTemporal(sbyte* address, Vector256 source) { throw new NotImplementedException(); } // void _mm256_stream_si256 (__m256i * mem_addr, __m256i a) [Intrinsic] public static unsafe void StoreAlignedNonTemporal(byte* address, Vector256 source) { throw new NotImplementedException(); } ...... } } ``` ### IMM Operands Most of the intrinsics can be directly ported to C# from C/C++, but certain instructions that require immediate parameters (i.e. imm8) as operands deserve additional consideration, such as `pshufd`, ` vcmpps`, etc. C/C++ compilers specially treat these intrinsics which throw compile-time errors when non-constant values are passed into immediate parameters. Therefore, CoreCLR also requires the immediate argument guard from C# compiler. We suggest an addition of a new ""compiler feature"" into Roslyn which places `const` constraint on function parameters. Roslyn could then ensure that these functions are invoked with ""literal"" values on the `const` formal parameters. ```csharp // Avx.cs namespace System.Runtime.Intrinsics.X86 { public static class Avx { ...... // __m256 _mm256_blend_ps (__m256 a, __m256 b, const int imm8) [Intrinsic] public static Vector256 Blend(Vector256 left, Vector256 right, const byte control) { throw new NotImplementedException(); } // __m256d _mm256_blend_pd (__m256d a, __m256d b, const int imm8) [Intrinsic] public static Vector256 Blend(Vector256 left, Vector256 right, const byte control) { throw new NotImplementedException(); } // __m128 _mm_cmp_ps (__m128 a, __m128 b, const int imm8) [Intrinsic] public static Vector128 Compare(Vector128 left, Vector128 right, const FloatComparisonMode mode) { throw new NotImplementedException(); } // __m128d _mm_cmp_pd (__m128d a, __m128d b, const int imm8) [Intrinsic] public static Vector128 Compare(Vector128 left, Vector128 right, const FloatComparisonMode mode) { throw new NotImplementedException(); } ...... } } // Enums.cs namespace System.Runtime.Intrinsics.X86 { public enum FloatComparisonMode : byte { EqualOrderedNonSignaling, LessThanOrderedSignaling, LessThanOrEqualOrderedSignaling, UnorderedNonSignaling, NotEqualUnorderedNonSignaling, NotLessThanUnorderedSignaling, NotLessThanOrEqualUnorderedSignaling, OrderedNonSignaling, ...... } ...... } ``` ## Semantics and Usage The semantic is straightforward if users are already familiar with [Intel C/C++ intrinsics](https://software.intel.com/sites/landingpage/IntrinsicsGuide/). Existing SIMD programs and algorithms that are implemented in C/C++ can be directly ported to C#. Moreover, compared to `System.Numerics.Vector`, these intrinsics leverage the whole power of Intel SIMD instructions and do not depend on other modules (e.g. `Unsafe`) in high-performance environments. For example, SoA (structure of array) is a more efficient pattern than AoS (array of structure) in SIMD programming. However, it requires dense `shuffle` sequences to convert data source (usually stored in AoS format), which is not provided by `Vector`. Using `Vector256` with AVX shuffle instructions (including shuffle, insert, extract, etc.) can lead to higher throughput. ```csharp public struct Vector256Packet { public Vector256 xs {get; private set;} public Vector256 ys {get; private set;} public Vector256 zs {get; private set;} // Convert AoS vectors to SoA packet public unsafe Vector256Packet(float* vectors) { var m03 = Avx.ExtendToVector256(Sse2.Load(&vectors[0])); // load lower halves var m14 = Avx.ExtendToVector256(Sse2.Load(&vectors[4])); var m25 = Avx.ExtendToVector256(Sse2.Load(&vectors[8])); m03 = Avx.Insert(m03, &vectors[12], 1); // load higher halves m14 = Avx.Insert(m14, &vectors[16], 1); m25 = Avx.Insert(m25, &vectors[20], 1); var xy = Avx.Shuffle(m14, m25, 2 << 6 | 1 << 4 | 3 << 2 | 2); var yz = Avx.Shuffle(m03, m14, 1 << 6 | 0 << 4 | 2 << 2 | 1); var _xs = Avx.Shuffle(m03, xy, 2 << 6 | 0 << 4 | 3 << 2 | 0); var _ys = Avx.Shuffle(yz, xy, 3 << 6 | 1 << 4 | 2 << 2 | 0); var _zs = Avx.Shuffle(yz, m25, 3 << 6 | 0 << 4 | 3 << 2 | 1); xs = _xs; ys = _ys; zs = _zs; } ...... } public static class Main { static unsafe int Main(string[] args) { var data = new float[Length]; fixed (float* dataPtr = data) { if (Avx2.IsSupported) { var vector = new Vector256Packet(dataPtr); ...... // Using AVX/AVX2 intrinsics to compute eight 3D vectors. } else if (Sse41.IsSupported) { var vector = new Vector128Packet(dataPtr); ...... // Using SSE intrinsics to compute four 3D vectors. } else { // scalar algorithm } } } } ``` Furthermore, conditional code is enabled in vectorized programs. Conditional path is ubiquitous in scalar programs (`if-else`), but it requires specific SIMD instructions in vectorized programs, such as compare, blend, or andnot, etc. ```csharp public static class ColorPacketHelper { public static IntRGBPacket ConvertToIntRGB(this Vector256Packet colors) { var one = Avx.Set1(1.0f); var max = Avx.Set1(255.0f); var rsMask = Avx.Compare(colors.xs, one, FloatComparisonMode.GreaterThanOrderedNonSignaling); var gsMask = Avx.Compare(colors.ys, one, FloatComparisonMode.GreaterThanOrderedNonSignaling); var bsMask = Avx.Compare(colors.zs, one, FloatComparisonMode.GreaterThanOrderedNonSignaling); var rs = Avx.BlendVariable(colors.xs, one, rsMask); var gs = Avx.BlendVariable(colors.ys, one, gsMask); var bs = Avx.BlendVariable(colors.zs, one, bsMask); var rsInt = Avx.ConvertToVector256Int(Avx.Multiply(rs, max)); var gsInt = Avx.ConvertToVector256Int(Avx.Multiply(gs, max)); var bsInt = Avx.ConvertToVector256Int(Avx.Multiply(bs, max)); return new IntRGBPacket(rsInt, gsInt, bsInt); } } public struct IntRGBPacket { public Vector256 Rs {get; private set;} public Vector256 Gs {get; private set;} public Vector256 Bs {get; private set;} public IntRGBPacket(Vector256 _rs, Vector256 _gs, Vector256_bs) { Rs = _rs; Gs = _gs; Bs = _bs; } } ``` As previously stated, traditional scalar algorithms can be accelerated as well. For example, CRC32 is natively supported on SSE4.2 CPUs. ```csharp public static class Verification { public static bool VerifyCrc32(ulong acc, ulong data, ulong res) { if (Sse42.IsSupported) { return Sse42.Crc32(acc, data) == res; } else { return SoftwareCrc32(acc, data) == res; // The software implementation of Crc32 provided by developers or other libraries } } } ``` ## Implementation Roadmap Implementing all the intrinsics in JIT is a large-scale and long-term project, so the current plan is to initially implement a subset of them with unit tests, code quality test, and benchmarks. The first step in the implementation would involve infrastructure related items. This step would involve wiring the basic components, including but not limited to internal data representations of `Vector128` and `Vector256`, intrinsics recognition, hardware support checking, and external support from Roslyn/CoreFX. Next steps would involve implementing subsets of intrinsics in classes representing different instruction sets. ## Complete API Design [Add Intel hardware intrinsic APIs to CoreFX #23489](https://github.com/dotnet/corefx/pull/23489) [Add Intel hardware intrinsic API implementation to mscorlib #13576](https://github.com/dotnet/coreclr/pull/13576) ## Update 08/17/2017 - Change namespace `System.Runtime.CompilerServices.Intrinsics` to `System.Runtime.Intrinsics` and `System.Runtime.CompilerServices.Intrinsics.X86` to `System.Runtime.Intrinsics.X86`. - Change ISA class name to match CoreFX naming convention, e.g., using `Avx` instead of `AVX`. - Change certain pointer parameter names, e.g., using `address` instead of `mem`. - Define `IsSupport` as properties. - Add `Span` overloads to the most common memory-access intrinsics (`Load`, `Store`, `Broadcast`), but leave other alignment-aware or performance-sensitive intrinsics with original pointer version. - Clarify that these intrinsics will not provide software fallback. - Clarify `Sse2` class design and separate small calsses (e.g., `Aes`, `Lzcnt`, etc.) into individual source files (e.g., `Aes.cs`, `Lzcnt.cs`, etc.). - Change method name `CompareVector*` to `Compare` and get rid of `Compare` prefix from `FloatComparisonMode`. 08/22/2017 - Replace `Span` overloads by `ref T` overloads. 09/01/2017 - Minor changes from API code review. " 22941 area-System.Drawing Clean up path validation related issues in System.Drawing.Common There were several places in the .NET Framework codebase for System.Drawing which called `IntSecurity.DemandReadFileIO(string);`. On first glance, this looks to be a CAS-related call, which isn't interesting in .NET Core. What isn't obvious is that this also ends up calling `Path.GetFullPath` on the string passed in, and that call may throw argument validation exceptions. If the path is `null`, for example, the security demand will result in an ArgumentNullException. These calls were omitted from the .NET Core version when I trimmed out all of the security demands. I've added these back, and fixed up several test cases which validated the behavior, and were previously disabled. Path.GetFullPath in .NET Core now correctly sets the `ParamName` property on its ArgumentException, so the assertions have been augmented to expect that. There were several tests which also expected some methods to result in a `PathTooLongException` being thrown from `Path.GetFullPath`. However, .NET Core no longer eagerly throws that exception from `Path.GetFullPath`. I have removed those test cases. @hughbe @KostaVlev 22943 area-System.Net BufferBuilder: Avoid unnecessary char[] and byte[] allocations Use `GetByteCount` and the overload of `GetBytes` that avoids the unnecessary `char[]` and `byte[]` allocations. 22944 area-Infrastructure Add retry to PDB conversion official build step "This brings in https://github.com/dotnet/buildtools/pull/1623, which adds a retry to the official build step that converts Portable PDBs to Windows PDBs.

"### Rationale Today, in C#, you can only invoke an unmanaged function pointer by first calling `Marshal.GetDelegateForFunctionPointer` and then invoking the resulting delegate that is created. This not only comes with the increased overhead of the call (`Marshal.GetDelegateForFunctionPointer`) itself, but it also incurs a heap allocation and a 4-6x memory increase, not including internal runtime allocations/overhead -- the `MulticastDelegate` type has an `object` and an `IntPtr` field and the base `Delegate` type itself has two `object` and two `IntPtr` fields -- Invoking the method also has some increased overhead as it goes through the `Delegate.Invoke` call rather than as a direct invocation. The C# language has planned support for `static delegates` in the future (https://github.com/dotnet/csharplang/blob/c5de26f52019ca0e1e79d88584f75bfe530ee986/proposals/static-delegates.md), but those may still be a way off and could potentially not come at all. Other languages may also face similar issues if they do not provide equivalent support. ### Proposal We should expose a new method on the `System.Runtime.CompilerServices.Unsafe` type that functions as an equivalent to the `calli` instruction. ```C# namespace System.Runtime.CompilerServices { public static class Unsafe { // Potential other names include: Call, Invoke, InvokeIndirect, Calli, etc... public static TResult CallIndirect(IntPtr ptr, params object[] args); } } ``` The runtime should treat this as an equivalent to the `calli` instruction with a signature matching `TDelegate`. The runtime should validate that `TResult`/`args` matches the return/input type of `TDelegate`. ### Other Thoughts Using generics means that pointers are harder to use, there would have to be support to interpret `IntPtr` and `UIntPtr` args (those passed to `CallIndirect`) as equivalent to a pointer (as declared for the corresponding field in `TDelegate`). The current proposal (using `params object[]`) means boxing for arguments, maybe having explicit ``, `` overloads would be better? * I can provide some details for the min/max/avg number of args the interop delegates take (at least for DirectX). I think, for either case, `out` and `ref` would not be readily supported unless `Unsafe.AsRef` were used internally (also having special handling to interpret `IntPtr` and `UIntPtr` as `ref` equivalents). ### Example Usage A user might have a manually authored interop type such as: ```C# [Guid(""7B7166EC-21C7-44AE-B21A-C9AE321AE369"")] unsafe public /* blittable */ struct IDXGIFactory { #region Fields public readonly Vtbl* lpVtbl; #endregion #region Delegates [SuppressUnmanagedCodeSecurity] [UnmanagedFunctionPointer(CallingConvention.ThisCall, BestFitMapping = false, CharSet = CharSet.Unicode, SetLastError = false, ThrowOnUnmappableChar = false)] [return: ComAliasName(""HRESULT"")] public /* static */ delegate int EnumAdapters( [In] IDXGIFactory* This, [In, ComAliasName(""UINT"")] uint Adapter, [Out] IDXGIAdapter** ppAdapter ); [SuppressUnmanagedCodeSecurity] [UnmanagedFunctionPointer(CallingConvention.ThisCall, BestFitMapping = false, CharSet = CharSet.Unicode, SetLastError = false, ThrowOnUnmappableChar = false)] [return: ComAliasName(""HRESULT"")] public /* static */ delegate int MakeWindowAssociation( [In] IDXGIFactory* This, [In, ComAliasName(""HWND"")] void* WindowHandle, [In, ComAliasName(""UINT"")] uint Flags ); [SuppressUnmanagedCodeSecurity] [UnmanagedFunctionPointer(CallingConvention.ThisCall, BestFitMapping = false, CharSet = CharSet.Unicode, SetLastError = false, ThrowOnUnmappableChar = false)] [return: ComAliasName(""HRESULT"")] public /* static */ delegate int GetWindowAssociation( [In] IDXGIFactory* This, [Out, ComAliasName(""HWND"")] void** pWindowHandle ); [SuppressUnmanagedCodeSecurity] [UnmanagedFunctionPointer(CallingConvention.ThisCall, BestFitMapping = false, CharSet = CharSet.Unicode, SetLastError = false, ThrowOnUnmappableChar = false)] [return: ComAliasName(""HRESULT"")] public /* static */ delegate int CreateSwapChain( [In] IDXGIFactory* This, [In] IUnknown* pDevice, [In] DXGI_SWAP_CHAIN_DESC* pDesc, [Out] IDXGISwapChain** ppSwapChain ); [SuppressUnmanagedCodeSecurity] [UnmanagedFunctionPointer(CallingConvention.ThisCall, BestFitMapping = false, CharSet = CharSet.Unicode, SetLastError = false, ThrowOnUnmappableChar = false)] [return: ComAliasName(""HRESULT"")] public /* static */ delegate int CreateSoftwareAdapter( [In] IDXGIFactory* This, [In, ComAliasName(""HMODULE"")] void* Module, [Out] IDXGIAdapter** ppAdapter ); #endregion #region Structs public /* blittable */ struct Vtbl { #region Fields public IDXGIObject.Vtbl BaseVtbl; public IntPtr EnumAdapters; public IntPtr MakeWindowAssociation; public IntPtr GetWindowAssociation; public IntPtr CreateSwapChain; public IntPtr CreateSoftwareAdapter; #endregion } #endregion } ``` In order to invoke `EnumAdapters` today, the user would code something similar to: ```C# var EnumAdapters = Marshal.GetDelegateForFunctionPointer(pFactory->lpVtbl->EnumAdapters); IDXGIAdapter* pAdapter; for (var adapterIndex = 0u; DXGI_ERROR_NOT_FOUND != EnumAdapters(pFactory, adapterIndex, &pAdapter); adapterIndex++) { // Check if the adapter supports D3D12 } ``` Under the proposal, someone would now declare: ```C# IDXGIAdapter* pAdapter; for (var adapterIndex = 0u; DXGI_ERROR_NOT_FOUND != Unsafe.CallIndirect(pFactory->lpVtbl->EnumAdapters, pFactory, adapterIndex, pAdapter); adapterIndex++) { // Check if the adapter supports D3D12 } ```" 22963 area-System.Security [release/1.1] Add newer shim package reference for Algorithms tests The Helix tests aren't seeing fixes made for macOS 10.13 because they are still using the 4.3.0 (RTM) native assets.

Before this change the behavior was: * Windows: NotSignatureValid * macOS: UntrustedRoot * Linux: UntrustedRoot With this change it becomes * Windows: NotSignatureValid * macOS: UntrustedRoot * Linux: NotSignatureValid | UntrustedRoot While additional work could be done to not report UntrustedRoot for Linux chains, it doesn't seem as worthwhile. macOS will continue not reporting NotSignatureValid, because there's no API to allow changing the behavior. Fixes #21622. 22968 area-System.Reflection Test class SRE GenericTypeParameterBuilderSetGenericParameterAttributes is wrong The `SetGenericParameterAttributes` test calls `GenericTypeParameterBuilder:SetGenericParameterAttributes` and then immediately accesses the `GenericParameterAttributes` property of the builder. According to https://msdn.microsoft.com/en-us/library/system.reflection.emit.generictypeparameterbuilder.setgenericparameterattributes(v=vs.110).aspx > Special constraints cannot be retrieved using methods of the GenericTypeParameterBuilder class. Once you have created the generic type that contains the type parameter, you can use its Type object to reflect the type parameters and their constraints. To get the type parameters of a completed generic type, use the Type.GetGenericArguments method. To get the special constraints for each type parameter, use the Type.GenericParameterAttributes property. So the test should first call `CreateType` on the generic class and then retrieve the parameter attributes.

However, inotify does tell us that if an event occurred on a directory or on a file after the event has been raised. Since this is after filtering has already been done, we forward that event regardless of the NotifyFilters. This commit passes NotifyFilters to the RunningInstance that forwards the events and adds in some manual filtering after the fact. It isn't quite the same as filtering through the native call, but it does bring us closer to the Windows behavior. cc: @JeremyKuhne @stephentoub @danwalmsley resolves https://github.com/dotnet/corefx/issues/21934 22977 area-System.Net Add HttpListenerWebSocketContext.WebSocket.Receive/Close throw ObjectDisposedException after disposal in managed implementation We should add a check `ThrowIfDisposed()` before checking for InvalidState in managed implementation.

I love the idea of validating by attributes, but it would be nice if we could extend the validation attribute a little bit. The downside of attributes, is that there are no generics, and no complex parameters so there is no nice way to extend the current behavior. So please add a few properties to the abstract `ValidationAttribute` class, there a many ways to think of how to gather the condition. Some of which are: - Expose a set of properties `PropertyName` and `IsEqualTo` that enables validation only when a property with the specified name equals the specified value. - Have the class implement an interface `IShouldValidate` etc. - Make it easier to attach/unattach metadata types for validation - Add a generic methods to `Validator` class, so it's easier to validate using `IValidatable` For example: `public ValidationResult ValidateValue(object value, Func setup = null);` Example usage (within `IValidatableObject.Validate`): yield return Validator.Validate(this.Name); (returns `ValidationResult`); yield return Validator.Validate(this.Age, () => new RangeAttribute(10, 20)); Would be also interesting to hear about more ideas and workarounds too. 22988 area-System.Net Add Span-based overloads to System.Net.Sockets Span-based synchronous overloads of: - Socket.Receive/Send - NetworkStream.Read.Write Contributes to https://github.com/dotnet/corefx/issues/22608 Contributes to https://github.com/dotnet/corefx/issues/22387 cc: @geoffkizer, @cipop, @davidsh, @KrzysztofCwalina (Buffer-based async overloads will be done later once `Buffer` is available.) 22992 area-System.Console Support for Console.MoveBufferArea() on Linux & Mac Is there a plan to support Console.MoveBufferArea() on Linux & Mac?

Since the eventual chain build would get them from the trusted path there's not a functional difference, but FindCandidates was doing an AIA fetch for the root certificates so it could complete it locally. This means that a lot of cert chain attempts use the network when they don't need to. So just keep those certs in the scan list to revert the network use regression." 23027 area-System.Net Avoid double dispose() check in ManagedWebSocket and ClientWebSocket From [comment in PR #22977 ](https://github.com/dotnet/corefx/pull/22977#discussion_r131529522): >ManagedWebSocket was originally written for use with ClientWebSocket, which already does such a disposal check: https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/src/System/Net/WebSockets/ClientWebSocket.cs#L164 We can wrap the ManagedWebSocket in HttpListener, and do the check in HttpListener instead.

I was hitting an intermittent test failure in the System.Drawing.Pens tests. The Unix implementation of Pens uses a pattern like this: ```C# public static Pen Green { get { if (green == null) { green = new Pen(Color.Green); green.isModifiable = false; } return green; } } ``` This is not thread-safe, and there is nothing stopping the underlying field from being assigned multiple times if two threads happen to run initialization code at the same time. I hit very occasional test failures where the same property returns two different values in the span of a test method, and an `Assert.Same` check fails. The Windows implementation already handles caching these variables in a thread-local storage location. I've simply deleted the Unix version of this code and switched the build configuration to use the Windows code. * Move the function imports into the shared Gdiplus.cs file, and remove the duplicated declarations from Gdiplus.Unix.cs and Gdiplus.Windows.cs. * Add basic argument validation into the shared code, so that we throw ArgumentExceptions up front, rather than as a result of a failure code from GDI+. * This change does affect the Windows version, but it should be functionally equivalent to before. 23033 area-System.Runtime Consider adding ArgumentIsNullOrEmptyException and ArgumentIsNullOrWhitespaceException to System Firstly, I tried to research if this had been proposed and did not find an existing issue. Of course, if one exists, please link to existing and close. I am aware that this usage can be captured by `ArgumentOutOfRangeException`, but these cases are so common that the System.String class itself has methods for just these checks, and they can provide a more specific default message when used like: `new ArgumentNullOrEmptyException(nameof(strParmeter));` then `ArgumentNullException` or `ArgumentOutOfRange` does. My proposal is that these would be subclasses of `ArgumentOutOfRangeException`. Of course, the momentum behind just using `ArgumentOutOfRangeException` may be so great to preclude the usefulness of such classes, but I believe the overall use cases they cover is common enough to warrant consideration. 23037 area-System.Net Test failure: System.Net.Http.Functional.Tests.HttpClientHandlerTest/SendAsync_RequestVersion20_ResponseVersion20IfHttp2Supported(server: https://http2.akamai.com/) Opened on behalf of @Jiayili1 The test `System.Net.Http.Functional.Tests.HttpClientHandlerTest/SendAsync_RequestVersion20_ResponseVersion20IfHttp2Supported(server: https://http2.akamai.com/)` has failed.

However, since SslStream throws away this value and doesn't update the fields in the class, this can cause excessive allocations to occur. (The allocation itself occurs in [`SslStreamPal`](https://github.com/dotnet/corefx/blob/cb173f6004e9671793d1aff64bab78e2d5f701c3/src/System.Net.Security/src/System/Net/Security/SslStreamPal.Windows.cs#L149)). At the moment I'm working around this by writing to the stream with very specifically-sized buffers (i.e. 4096-bytes), which means that the new allocation doesn't occur.

Dynamic compilation works with smaller units, and its atomising lives in memory forever, rather than for a compilation operation. As such the benefits of atomising are less and the costs greater. Use strings directly, instead. Since much of the benefit of the predefined names is in seeding this set, use strings directly in that case, too. It's hard to determine how best to measure performance impact. I used a case that did a few different dynamic operations: ```C# private static int dump; [Benchmark] public void TempPerformanceTest() { foreach (var iteration in Benchmark.Iterations) { using (iteration.StartMeasurement()) { for (int i = 0; i < 1000000; i++) { dynamic x = 23; dynamic y = 47; dynamic z = x * y; dynamic s = z.ToString(); dynamic bu = new Uri(""http://example.net/""); dynamic u = new Uri(bu, s + s.Length); dynamic p = u.AbsolutePath; dynamic b = string.IsNullOrWhiteSpace(p); dynamic r = b ? x : y; dump = r; } } } } ``` ### Before |Test Name|Metric|Iterations|AVERAGE|STDEV.S|MIN|MAX| |---------|------|----------|-------|-------|---|---| Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2878.11260689472|151.795343740538|2711.06853438242|3020.87581481642 Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2648.36714824399|10.0406400805859|2637.46739684668|2661.6017775862 Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2736.14701287239|124.428088134655|2665.10479426716|2922.5105092833 Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2718.26595309438|131.364382921837|2633.53285926681|2913.24330641109 Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|3|3407.81461799982|656.868131469811|2668.76362498082|3925.08470638618 |||||| |Ave, Max, Min of above|||2877.74146782106||2633.53285926681|3925.08470638618| ### After |Test Name|Metric|Iterations|AVERAGE|STDEV.S|MIN|MAX| |---------|------|----------|-------|-------|---|---| |Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2850.54017086362|182.223336989238|2735.97218859469|3122.08495970061| |Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2642.93826545393|43.5051180165349|2589.54291906861|2691.64449582264| |Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|3004.94557938328|231.242920652251|2830.25040807882|3341.45525641438| |Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2653.03935330645|61.1607418566276|2587.7883784191|2734.57779295487| |Microsoft.CSharp.RuntimeBinder.Tests.TempPerformance.TempPerformanceTest|Duration|4|2750.33040505584|165.351254692047|2588.9093997381|2935.01715120632| ||||||| |Ave, Max, Min of above|||2780.35875481262||2587.7883784191|3341.45525641438| The two are within each other's margin of error, but there is an average improvement of around 3%, along with the assembly no longer holding atomised strings in memory indefinitely, and the result being IMO simpler." 23049 area-Meta Add ref/tests for Span-based Encoding APIs cc: @KrzysztofCwalina, @tarekgh Fixes https://github.com/dotnet/corefx/issues/22431 Depends on https://github.com/dotnet/coreclr/pull/13269 23054 area-Infrastructure Can we extend the timeout on the coverage builds?

Encoding, but we didn't discuss the lower-level Encoder/Decoder types. @jkotas reminded me of this in https://github.com/dotnet/coreclr/pull/13269#issuecomment-321020525, and upon taking a look, I expect methods like the following are the ones we'd want to add: ```C# namespace System.Text { public abstract class Encoder { public virtual void Convert(ReadOnlySpan chars, Span bytes, bool flush, out int charsUsed, out int bytesUsed, out bool completed); public virtual int GetByteCount(ReadOnlySpan chars, bool flush); public virtual int GetBytes(ReadOnlySpan chars, Span bytes, bool flush); ... } public abstract class Decoder { public virtual void Convert(ReadOnlySpan bytes, Span chars, bool flush, out int bytesUsed, out int charsUsed, out bool completed); public virtual int GetCharCount(ReadOnlySpan bytes, bool flush); public virtual int GetChars(ReadOnlySpan bytes, Span chars, bool flush); } } ``` @tarekgh, thoughts, both on exposing such methods and on the specific ones I've listed?

There was an initial API proposal in issue #4721 however this stalled from my reading because of two issues 1. It would break compat with desktop 2. It would make the AuthenticateAsXXXXX method overloads become unwieldy So I think the need has been established just not the API Design and therefore the implementation. #Proposed API change --- I would propose adding extension methods for SslStream. ``` csharp public static SslStreamExtensions { public delegate void ApplicationLayerProtocolCallback(object sender, string matchedProtocol); public delegate bool ServerNameIndiciationCallback(object sender, string serverName, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors); public void SetApplicationLayerProtocolNegotiation(this SslStream self, string[] supportedProtocols, ApplicationLayerProtocolNegotiationCallback callback) {} public void SetServerNameIndiciation(this SslStream self, Dictionary serverCertificates, ServerNameIndiciationCallback callback) {} } ``` One other potential idea is to move this off to a ""Builder"" method for SslStream. This might help in the server scenario as multiple SslStreams could be built from it and components that each can share could be reused (for instance SSL_CTX in openssl is only required 1x for the same settings rather than per connection). # Example Usage --- ``` csharp var supportedProtocols = new string[] {""http1.1"", ""h2""}; var supportedServerNames = new Dictionary() { ""www.myanimatedgifsrock.com"" , new X509Certificate(""secretpath"", ""secretpassword""), ""www.immoslesscoolgifs.com"", new X509Certificate(""expiredcertpath"", ""secretpassword2""), }; var SslStream stream = new SslStream(networkStream); stream.SetApplicationLayerProtocolNegotiation(supportedProtocols, MyAlpnHandler); stream.SetServerNameIndiciation(supportedServerNames, MySniHandler); //normal use resumes ``` # Referenced Issues --- #9608 SNI #4721 ALPN # Potential Issues --- The callback for SNI should need to (and does in above) provide the ability to validate the certificate. Consideration would need to be given to the concept that if the SNI callback provides this what happens if a callback is provided in the Authenticate method. Also should there be separate extension methods for client and for server? Maybe but really you probably want both to have the chance to decide if they are happy with the otherside based on the servername that they tried to connect to. The other issue with this pattern is that there is no ""state"" held in the SslStream. Once the callback has been called there is no real way to retrieve this information later and it would be up to the user to associate this information with the SslStream and carry it around. To this end perhaps an extension method/methods to later retrieve this information might be considered such as below ``` csharp public static bool TryGetApplicationLayerProtocol(this SslStream self, out string protocol); public static bool TryGetServerName(this SslStream self, out string serverName); ``` Thanks :)" 23080 area-System.Linq Suggestion: Enumerable.ToReadOnly Please include a LINQ extension `ToReadOnly` (and `ToReadOnlyAsync` (for `IQueryable`, in `System.Data.Entity.QueryableExtensions`), which should return a readonly list of the enumerated result. 23085 area-System.Runtime System.ValueTuple now supports .NET Framework 4.7 # Summary The NuGet package System.ValueTuple [has been updated](https://www.nuget.org/packages/System.ValueTuple/4.4.0) to support .NET Framework 4.7. # Details The NuGet package provides the `ValueTuple` types which are required for the C# tuple syntax. In .NET Framework 4.7 we've added the types directly to `mscorlib`. If you use both, the NuGet package, as well as .NET Framework 4.7 you'll end up seeing the same types multipe times. This results in issues like this one [reported on Stack Overflow](https://stackoverflow.com/questions/45339914/predefined-type-system-valuetuple-is-not-defined-or-imported-after-upgrading-t). We've updated the NuGet package to type forward the tuple types on .NET Framework 4.7 to `mscorlib`. This unifies the types and thus allows you to consume other libraries and NuGet packages that depend on `System.ValueTuple` while still targeting .NET Framework 4.7. 23086 area-Meta Consistency of sealed modifiers on methods of sealed classes The general style across corefx is that if a type is sealed, its virtual members are not also annotated as sealed.

This makes the epoll thread a bottleneck. Instead, rework the queue processing logic so that we dispatch a workitem to the threadpool to perform the IO and then call the user's callback directly. This results in the same amount of ""thread-hopping"", but the actual IO work is moved off the epoll thread, which should hopefully make it less of a bottleneck. Additionally, rework the queue locking logic to ensure that our locking is as fine-grained and short-lived as possible. I don't have perf data on this change yet due to some infrastructure issues, will get this as soon as I can. @stephentoub @wfurt @Priya91 @pgavlin @vancem @dotnet-bot test Outerloop Linux x64 Debug Build @dotnet-bot test Outerloop Windows x64 Debug Build @dotnet-bot test Outerloop OSX x64 Debug Build " 23116 area-Infrastructure Packages built from master incorrectly target netcoreapp2.0 Opened with @ericstj Changes like https://github.com/dotnet/corefx/commit/1d3cc0417753bf0a436824abfeff9c3c1712f63f have moved components inbox for `netcoreapp2.0` but those components were not inbox in the actual 2.0 release.

They need to be investigated and either src or tests fixed. 23141 area-System.Net [ManagedHandler] Improve cancellation support when sending/receiving data The ManagedHandler_CancellationTest tests are disabled because sockets don't support canceling individual operations. We might be able to address this once https://github.com/dotnet/corefx/issues/22608 is implemented and the associated cancellation support is enabled. We could also employ a variety of workarounds, including ending the whole request on cancellation by disposing of the connection, wrapping the operations in ones that can be canceled even though the underlying operation may continue running, etc. 23142 area-System.Net [ManagedHandler] Implement MaxResponseHeadersLength We currently don't track the amount of header data received, and thus don't enforce MaxResponseHeadersLength. 23143 area-System.Net ManagedHandler: Size overflow needs to be handled in ParseHexSize We should just see how WinHttpHandler and CurlHandler handle overflow here, and do the same. 23144 area-System.Net ManagedHandler: Support Expect: 100-continue We need to add support for this. 23145 area-System.Net ManagedHandler: Enable duplex communication Currently the ManagedHandler waits for all of the request content to be sent before parsing the response content. This prohibits duplex communication and needs to be fixed (both in general, and to be able to reuse the underlying types here in the managed ClientWebSocket implementation). 23146 area-System.Net ManagedHandler: Better cancellation support when transferring request body Currently cancellation is ignored while the request body is being transferred. 23147 area-System.Net [ManagedHandler] Avoid string allocations while parsing headers 23148 area-System.Net ManagedHandler: Move text into .resx There are currently strings littered throughout the code. If they'll be user visible (e.g. exception messages), we should move them into the .resx and unify them with the existing messages, avoiding duplication where possible. 23149 area-System.Net ManagedHandler: Improve timer management in HttpConnectionPools Currently the timer continues to run even if there are no active connections on any pool. 23150 area-System.Net [ManagedHandler] Support Windows & Unix environment variables for proxy configuration libcurl and other clients respect an established convention for environment variables used to configure proxies. We should respect these in ManagedHandler as well. 23151 area-System.Net ManagedHandler: Support canceling opening connections Right now we use the instance socket.ConnectAsync method, which doesn't give us a way to cancel the connection. We should investigate other approaches that would allow us to do so, e.g. with SocketAsyncEventArgs and its connection cancellation support, or worst case, disposing of the socket (though that might have reliability concerns). 23152 area-System.Net ManagedHandler: Use the managed handler in ClientWebSocket's managed implementation This depends on #23145. 23153 area-System.Net [ManagedHandler] Investigate adding NTLM auth support 23154 area-System.Net [ManagedHandler] Investigate adding Negotiate auth support 23155 area-System.Net Update TODOs in ManagedHandler "I cleaned up the TODOs in ManagedHandler, opening individual issues for each aspect and updating the comments to link to the associated issue. In the process of doing so, I found that some of the ""hangs"" reported were due to test issues, where the tests would hang if the HttpClient.GetAsync operation failed, so I fixed those such that we now see the actual reason for the failure rather than the test hanging. And I added a bit more tracing to ManagedHandler, in particular to see details about the established SSL connection. cc: @geoffkizer " 23156 area-System.Net [ManagedHandler] Investigate adding connection draining support Today when we cancel/dispose a response and we've not yet handled all of the expected response data from the server, we abandon the connection rather than putting it back into the pool. We should investigate adding support for draining the remaining data from the connection, and whether it's worthwhile from a performance perspective (maybe just for https, given the additional overhead associated with establishing the connection?).

They are needed urgently to support Http/2 (ALPN) and the ability to run Kestrel as an edge server (SNI). There are also many other customer applications that require this, including Clients being able to use HTTP/2 (Mananed HttpClient has an Http/2 support open issue). These have been outstanding for a long period of time, for a number of reasons. One major reason is that any change will cause an increase in overloading of the Authenticate methods which have become unwieldy and are brittle when adding new options. There will be more options coming with other TLS extensions available now (max fragment size for restricted memory clients for instance) and having a mechanism to add these without major API changes seems like a sensible change. ## Proposed API Change Originally I suggested overloading the Authenticate methods, however discussions in #23077 have changed my mind. Thanks to @Tratcher for this concept ``` csharp public partial class SslStream { public Task AuthenticateAsServerAsync(SslServerAuthenticationOptions options, CancellationToken cancellation) { } public Task AuthenticateAsClientAsync(SslClientAuthenticationOptions options, CancellationToken cancellation) { } public SslApplicationProtocol NegotiatedApplicationProtocol {get;} } public class SslServerAuthenticationOptions { public bool AllowRenegotiation { get; set; } public X509Certificate ServerCertificate { get; set; } public bool ClientCertificateRequired { get; set; } public SslProtocols EnabledSslProtocols { get; set; } public X509RevocationMode CheckCertificateRevocation { get; set; } public IList ApplicationProtocols { get; set; } public RemoteCertificateValidationCallback RemoteCertificateValidationCallback { get; set; } public EncryptionPolicy EncryptionPolicy { get; set; } } public class SslClientAuthenticationOptions { public bool AllowRenegotiation { get; set; } public string TargetHost { get; set; } public X509CertificateCollection ClientCertificates { get; set; } public LocalCertificateSelectionCallback LocalCertificateSelectionCallback { get; set; } public SslProtocols EnabledSslProtocols { get; set; } public X509RevocationMode CheckCertificateRevocation { get; set; } public IList ApplicationProtocols { get; set; } public RemoteCertificateValidationCallback RemoteCertificateValidationCallback { get; set; } public EncryptionPolicy EncryptionPolicy { get; set; } } public struct SslApplicationProtocol : IEquatable { public static readonly SslApplicationProtocol Http2; public static readonly SslApplicationProtocol Http11; // Adding other IANA values, is left based on customer input. public SslApplicationProtocol(byte[] protocol) { } public SslApplicationProtocol(string protocol) { } // assumes utf-8 and public override public ReadOnlyMemory Protocol { get; } public bool Equals(SslApplicationProtocol other) { } public override bool Equals(object obj) { } public override int GetHashCode() { } public override string ToString() { } // For debugger. utf-8 or a string representation of the raw bytes. E.g. ""0x68 0x74 0x74 0x70 0x2f 0x31 0x2e 0x31"" public static bool operator ==(SslApplicationProtocol left, SslApplicationProtocol right) { } public static bool operator !=(SslApplicationProtocol left, SslApplicationProtocol right) { } } ``` ## Meeting Notes 22-Sep-2017 1. Add ToString() to SslApplicationProtocol to get string version of the bytes. 2. Add string ctor to SslApplicationProtocol for usability, this will assume it's utf8 string. 3. ReadOnlyMemory is not immutable, we need to copy the bytes in the ctor, so taking a byte[] instead of ReadOnlyMemory ## Meeting Notes 5-Sep-2017 1. Use the updated API proposal above with options bags on the Authenticate methods. 2. Introduce an ApplicationProtocol type so the ALPN values can be correctly defined as raw bytes, have shared constants, and have equality operators. 2. Disallow mixing calls between the old constructors and the new methods. Only the minimal constructors taking the inner stream and ownership bool will be supported. 3. There is still some pending discussion on the factory approach. ## Further Notes 1. This will mean future options can be added without causing binary compatibility issues (increasing properties on concrete classes rather than changing overloads) 1. Non async methods shouldn't be supported for the new methods as it is an async operation under the hood so hiding the threads goes against current framework thinking. Consumers can wrap the async methods with blocking if they so wish (see modern HttpClient ) 1. I snuck max fragment in for the client, but I am happy to have this dropped if it is a sticking point 1. Cancellation tokens are there for both methods as per current framework thinking 1. ValueTask wasn't considered because there will be very few times this doesn't cause async operations, but if the new standard is to use ValueTask that is fine as well 1. A static list of the Http 1.1, Http/2 and Http/2 over TLS should be provided to stop users having to look it up. 1. Helper methods on the auth results should be provided so users don't have to look up what the string representations are in this case I added one for IsHttp2. ## Potential Implementation Issues There are now a number of parameters that could be modified during an connection being created. One of these is the certificate dictionary. If the consumer changes these by accidentally reusing the config options for a differently configured connection you could run into a security issue. One option is to have a builder but this is frowned upon as an API pattern and instead mostly used in higher level libraries/frameworks (ASP.NET for instance). This is solvable via taking an internal snapshot of the options but will need to be considered in any threat modelling. ## Example Usage ``` var options = new ServerAuthenticationOptions() { EnabledProtocols = SslProtocols.Tls12 | SslPRotocols.Tls11, ApplicationProtocols = new List() { ApplicationProtocol.Http2, ApplicationProtocol.Http11 } }; var secureStream = new SslStream(innerStream); await secureStream(options, token); ``` ## References #9608 SNI #4721 ALPN #23077 Previous API proposal [RFC 7301 ALPN](https://tools.ietf.org/rfc/rfc7301.txt) [RFC 3546 SNI and Max fragment](https://www.ietf.org/rfc/rfc3546.txt) [IANA ALPN Protocol Ids](https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#alpn-protocol-ids) [EDIT] Updated formatting by @karelz" 23180 area-System.Net Enable full duplex communication with ManagedHandler ManagedHandler currently waits for all of the request content to be sent before it processes any response content. While that matches with what many servers do (not sending any response content until all request content has been received), some sites and situations do benefit from or even require full duplex communication, such that the response can be processed even while the request content is being sent. This change is also a necessary step towards enabling Expect: 100-continue, as we need to be able to receive the response header before having sent the content, and even without Expect: 100-continue, this allows us to stop sending a large request body if a server quickly sends back a status indicating the transfer isn't needed (e.g. a redirect). This change also improves on the cancellation support for sending the request body. The send cancellation token is now embedded in the request content stream and uses that token for all operations.

In this PR, I've removed argument validation for a couple of `ImmutableList` functions. I did this since I noticed many functions validated their arguments twice, once in `ImmutableList` and once in `ImmutableList.Node`. It's simpler if we just omit validation for the former and let the `Node` class take care of it. There were a few places where `ImmutableList` and `Node` validated arguments differently. For those cases, I copied and pasted the `ImmutableList` validation into the `Node` method to preserve exception behavior. /cc @safern, @ianhays, @AArnott 23240 area-System.Runtime Proposal: Enum.IsDefined() I am aware of the issues https://github.com/dotnet/corefx/issues/10692 and https://github.com/dotnet/corefx/issues/15453. However, https://github.com/dotnet/corefx/issues/10692 isn't a formal proposal, and https://github.com/dotnet/corefx/issues/15453 will take forever to get through because it has so much other stuff. I think this API is valuable enough that I am opening a new issue to expedite things. ## Proposal ```cs namespace System { public abstract class Enum : ValueType, IComparable, IConvertible, IFormattable { public bool IsDefined(); } } ``` ## Performance The new API doesn't need to have great performance. (Yes, it will still box.) 99% of the time I use this in `Debug.Assert`, so it has no effect on release perf. Also, as @benaadams mentions in the first issue, this is faster than the existing `IsDefined` method because > Enum.IsDefined(typeof(MyEnum), argument) is also quite slow as it needs to do lots of conversion checks etc; whereas if you already have the enum these don't need to be done. It's faster and terser than the existing method and it's used very often, so it seems reasonable to add this, no? **edit:** If for whatever reason the boxing becomes a performance problem, we can consider making the method an intrinsic to avoid it (just like https://github.com/dotnet/coreclr/pull/7895 avoided boxing for `Enum.GetHashCode`). 23242 area-System.Drawing Adding System.Drawing.Printing PrinterSettings tests.

This makes it harder to inspect contents to make informed decisions on its contents to drive logic. For instance, determining if a key was present in a named capture group before trying to perform logic with the result. This can be seen as a follow-on to issue #271 (it was listed in the Open Questions section). Rationale and Usage ----------------------- This was something I stumbled upon when trying to make a RegEx expression in two forms, one with a lot of named parameters, but that were all optional. I wanted to check if the parameters existed before proceeding to perform logic with them but discovered that there was no method to check if a named capture group was actually captured. Currently, I can use an indexer to access a specific group name like ``` match.Groups[""options""] ``` But unlike a normal dictionary, I can't call ```match.Groups.ContainsKey('options"")``` to see if it exists first before retrieval if I have optional named capture groups. The current Contains method only checks on the **object** not the named key. Currently, the group if *not* captured returns an empty string, but that is a bit misleading, as the group could have been captured but contained no data. So, there's an ambiguous state. If we had methods to check if the capture was performed, we could leave the group out and have KeyNotFoundExceptions or nulls to differentiate from existence vs. no data. This would let us then do: ``` if (match.Groups.ContainsKey(""options"")) { // do something with match.Groups[""options""] } ``` OR ``` Group options; if (match.Groups.TryGetValue(""options"", out options)) { // do something with options group now. } ``` Proposed API --------------- ``` public GroupCollection : IReadOnlyDictionary, ... { bool ContainsKey(string key); bool TryGetValue(string key, out Group group); ... } ``` Details ------- - As mentioned, this was an Open Question of #271 that wasn't resolved. It should be a fairly straight-forward addition to the class.

I'm relatively new to .NET core, so I don't know if I'm doing something wrong here. For testing purposes, have written 3 methods that do the same thing in different ways: all of them write some content to a random file, and then delete it. ```c# static async Task WriteAllTextAsync() { string fileName = System.Guid.NewGuid().ToString(); await File.WriteAllTextAsync($""write/{fileName}.txt"", content); File.Delete($""write/{fileName}.txt""); } static void WriteAllText() { string fileName = System.Guid.NewGuid().ToString(); File.WriteAllText($""write/{fileName}.txt"", content); File.Delete($""write/{fileName}.txt""); } static async Task WriteWithStreamWriter() { string fileName = System.Guid.NewGuid().ToString(); using (StreamWriter outputFile = new StreamWriter($""write/{fileName}.txt"")) { await outputFile.WriteAsync(content); } File.Delete($""write/{fileName}.txt""); } ``` I am using the following loop to call these methods: ```c# for (int i = 0; i < 200; ++i) { //""method()"" or ""await async_method()"" } ``` I've noticed that `WriteAllTextAsync` is significantly slower than the other methods and results in higher disk usage (no fancy benchmarks here, the HDD led on my pc just stays turned on when using this method). Using `time` on each method gives the following results: ``` WriteAllTextAsync real 0m14.579s user 0m4.314s sys 0m0.460s WriteAllText real 0m4.244s user 0m4.116s sys 0m0.418s WriteWithStreamWriter real 0m4.243s user 0m4.133s sys 0m0.432s ``` As expected, the results using `File.WriteAllText` (synchronously) and StreamWriter.WriteAsync (asynchronously) are very close, but `File.WriteAllTextAsync` is much slower.

Knuth's subtractive random number generator algorithm. For more information, see D. E. Knuth. ""The Art of Computer Programming, volume 2: Seminumerical Algorithms"". Addison-Wesley, Reading, MA, second edition, 1981. > > The problem was discovered when I use .NET Reflector to see what is actually implemented. Knuth was very specific about the lagged Fibonacci sequence coefficient (24 and 55). Somehow Microsoft mistyped the value to be 21 (this.inextp = 0x15 in public Random(int Seed) in source code), in place of 31 (=55-24). Due to this mistype, the random number generated no longer has the guanrantee on the period to be longer than (2^55-1). The Knuth version of lags (24, 55) has been tested by many people about the property of the generated numbers but not the one created by Microsoft. > > It is very easy to identify the typo. It seems that Microsoft just copied the routine (ran3) from Numerical Recipes v.2 page. 283 verbatim (even the variable names are copied), not from Knuth book which has a complete different way of initializing. You see that Numerical Recipe version uses 31 correctly, not 21 used by Microsoft.

I'm not sure what the implication of our deviation is. If we wanted to fix it, we'd likely would have to quirk the implementation on .NET Framework.

The src/Native/ build script has option to specify different version but that is not exposed to top level scripts (build.sh and build-native.sh) This is somewhat unpleasant as for example we require minimum 3.9 for arm so available 3.8 should work just fine. I think there are two possible stages for fix: #1 expose clang option to root build script and make sure it works. #2 detect available clang and use closest desired match similar to way how coreclr does. 23300 area-Meta ASP.NET Core with Docker support: Connection refused "I have a ASP .NET Core (v2.0) app with Docker support.

The options are really inconsistent, some starting with --XX, some -YY and some ZZZ. To keep it consistent wit top level options and help I added -Clang=XYZ so one can pass any string without need to update script for every new clang version (which builds-managed.sh clangx.y does) There are also three more minor improvements: 1. -h works now same way as -? (it always did for src/Native/build-native.sh) 2. - we do not try to use options starting with '-' as directory. Preferably the check -d $1 should skip all options like normal scripts do or there should be explicit option for that. 3. we use ""$@"" instead of $* to properly handle arguments with spaces. I did this while back but it got rolled back because it exposed some other problem (which is fixed now) I did test build on Ubuntu 17.04 ./build.sh -Clang=clan3.8 I also did basic testing on OSX. ./build.sh -h ...

Story: - Existing .NET 4.6 application, including System.Threading.Tasks.Dataflow 4.7.0 nuget package and System.Net.Http 4.3.2 package, redirects for System.Net.Http are configured - Nuget offers update of Dataflow to V 4.8.0 - After update, redirects for System.Net.Http warn that I should redirect to V 4.2.0 Note: If I don't touch the nuget update at all, no build errors occur Steps to reproduce in a small repro: 1. Create .NET 4.6 project 2. Add reference to Nuget System.Net.Http (V 4.3.2) package 3. Add binding redirect to ```xml ``` 4. Compile (no warnings) 5. According to Project references the Assembly version of System.Net.Http.dll is 4.1.1.1 6. Add reference to one of (there are probably more packages) - System.Threading.Tasks.Dataflow nuget (V4.8.0) - System.Buffers (V4.4.0) 7.

Workaround: - Do what it suggests and replace the redirect with ```xml ``` I don't know why the build suddenly uses a library from the VS program directory and not from the NuGet packages.

For readability, you could also include argument names: ```csharp source.CopyToAsync(target, bufferSize: 81920, cancellationToken: cancellationToken); ``` This leads to some really verbose code, and in the majority of cases, I just want to stick with the default buffer size. With the proposed overload, the above code would end up looking like this: ```csharp source.CopyToAsync(target, cancellationToken); ``` I realize that this could be implemented as an extension method, but since the default buffer size constant is private, you end up having to copy it and future tweaks would not follow. There's also [various optimizations inside `CopyToAsync`](https://github.com/dotnet/coreclr/blob/a6045809b3720833459c9247aeb4aafe281d7841/src/mscorlib/src/System/IO/Stream.cs#L125-L152) that you'd have to reimplement. ## Proposed API ```diff namespace System.IO { public abstract class Stream : MarshalByRefObject, IDisposable { public Task CopyToAsync(Stream destination) public Task CopyToAsync(Stream destination, Int32 bufferSize) + public Task CopyToAsync(Stream destination, CancellationToken cancellationToken) public virtual Task CopyToAsync(Stream destination, Int32 bufferSize, CancellationToken cancellationToken) } } ``` ## Details - The implementation would just call into the (virtual) overload using the default buffer size." 23313 area-System.Net [ManagedHandler] Explore use of .netrc (config for authentication - general/proxy) https://ec.haxx.se/usingcurl-netrc.html it seems like curl can use it but I'm not sure if libcurl would on linux with c# The come up in are of configuring proxy, but there may possibly be more, like authentication details. 23315 area-Infrastructure Disable dumpling Seeing issues installing the dumpling package.

These are only included in the UAP build. Adds tests for the brokered IO WinRT functions and removes a dead option from movefile. This option was removed in Windows 8 and did not work correctly in prior OSes. (This was needed for this change.) This change depends on the referenced dll being packaged and added to our dependencies. There is a related change for CoreCLR that supports FileStream. Note: I broke out the struct defines and put all of the new P/Invokes in a single file. I want to keep them together and in the FileSystem dir to help keep them from creeping out and allow for easy disabling if required. There is one known issue at this point with setting of attributes in brokered locations. Everything else is to the point where it looks like our code is correct. 23317 area-System.Collections [Question] System.Collections.Immutable.ImmutableDictionary reorders "This is probably by design to help with the immutable types, but why does an ImmutableDictionary reorder keys after adding?

Fixes #23334 23336 area-Meta Unable to resolve service for type 'Core.Data.CoreContext' while attempting to activate 'Core.Data.Repositories.UnitOfWork' I have part of WebAPI application that I want to move to separate project as class library. It is common base structure that almost every app has so idea is to make it easy shareable. What I have done in that direction is created a project named Core and moved those shared elements there, including Base Entities (e.g. User, Settings, etc), CoreContext, UnitOfWork, Generic Repository, BaseRepositories,... In the Main project of app there are others Entities, AppContext that inherits CoreContext, more Repositories, and all Controllers, ... I was able to build the app but when after starting it get the following error: > InvalidOperationException: Unable to resolve service for type 'Core.Data.CoreContext' while attempting to activate 'Core.Data.Repositories.UnitOfWork'. >Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteFactory.CreateArgumentCallSites(Type serviceType, Type implementationType, ISet callSiteChain, ParameterInfo[] parameters, bool throwIfCallSiteNotFound)... Problem seems to be that `UnitOfWork` class is in Core project and in Main project is `Startup.cs` with method` ConfigureServices` that has `services.AddTransient();`. Is this a bug or am I just not configuring it correctly and how could it be achieved, if possible at all. ### Further technical details NetCore & EF Core version: 2.0 Database Provider:

DNS is configured with one IP (behind there are several servers) and redirect to one web server. To test one server in web farm, in framework 4.6.2, I use with sample code: ```C# string host = ""www.ebay.fr""; IPHostEntry hostEntry; hostEntry = Dns.GetHostEntry(host); ///// HttpClient Test HttpClientHandler httpClientHandler = new HttpClientHandler(); HttpClient client = new HttpClient(httpClientHandler); client.BaseAddress = new Uri(""https://"" + hostEntry.AddressList[0].ToString()); client.DefaultRequestHeaders.UserAgent.ParseAdd(""Mozilla/5.0 (compatible;"" + DateTime.Now + "" "" + DateTime.Now.Millisecond + "")""); client.DefaultRequestHeaders.Host = host; HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, client.BaseAddress); request.Headers.Host = host; request.Headers.UserAgent.ParseAdd(""Mozilla/5.0 (compatible;"" + DateTime.Now + "" "" + DateTime.Now.Millisecond + "")""); Task task = client.SendAsync(request); task.Wait(); HttpResponseMessage respones = task.Result; ``` With framework 4.6.2, it is work fine. **But in .net core 2**, with a test on IIS server web server, the connexion close when web client try to negociate SSL. Here I use ""ebay"" server but it is work on it. I don't found a IIS server on web. My web farm is not access from web. I debug the connection with WireShark to see the network data: **With .net core2** ![image](https://user-images.githubusercontent.com/20461115/29434016-b34561e2-83a1-11e7-81f8-2f2af5786660.png) **With Framework 4.6.2** ![image](https://user-images.githubusercontent.com/20461115/29434003-aa4457ba-83a1-11e7-9d9c-04dd54f65982.png) 📌 I think the issue is with .net core, **the extension server_name is not defined**. IIS server should need known the certificat to take. .net core 2 should define server_name from client.DefaultRequestHeaders.Host or request.Headers.Host (even if BaseAddress is an IP) ? **For more information:** [https://idea.popcount.org/2012-06-16-dissecting-ssl-handshake/](url) > TLS introduces a number of extensions. Most notably the server_name / Server Name Indication (SNI) extension is used to specify a remote host name. This allows the server to choose appropriate certificate based on the requested host name. With this extension one can host many SSL-enabled vhosts on a single IP address.

That is what msbuild asked for and was also most convenient for me when I wrote that code a while ago. Should we have other overloads, PEMemoryBlock, ImmutableArray, byte[], BlobReader? We have a mix for other similar things and don't directly provide Streams.

The reason this came up is because I noticed that the color output from `dotnet xunit` was broken, as we rely on bright colors when writing our output.

Examples of such can be found in languages like [Elm's Dict module](http://package.elm-lang.org/packages/elm-lang/core/latest/Dict#combine), but there are also multiple questions about it on the C# tags of StackOverflow, pointing that this is a desired feature. Example: ```csharp var left = ImmutabeDictionary.CreateRange(new Dictionary { { ""a"", 1 }, { ""b"", 2 } }); var right = ImmutabeDictionary.CreateRange(new Dictionary { { ""b"", -1 }, { ""c"", 7 } }); var merged = left.Merge(right, (key, leftValue, rightValue) => leftValue + rightValue); // => { (""a"", 1), (""b"", 1), (""c"", 7) } var intersected = left.Intersect(right, (key, leftValue, rightValue) => leftValue + rightValue); // => { (""b"", 1) } var diff = left.Except(right); // => { (""a"", 1) } ``` ### Proposed API ```csharp interface IImmutableDictionary where TKey: IComparable { IImmutableDictionary Intersect(IImmutableDictionary other, Func onEqual); IImmutableDictionary Except(IImmutableDictionary other); IImmutableDictionary Merge(IImmutableDictionary other, Func onEqual); IImmutableDictionary Merge(IImmutableDictionary other, Func onEqual, Func onLeft, Func onRight); } ``` ### Details - `Intersect` and `Except` methods would work just like their equivalents in `IImmutableSet<>` API (distinct elements are recognized by key). In case of intersection, we need a method to resolve conflict between two different values in each dictionary (given the same key). - `Merge` method works like set union, but as we need to recognize distinct elements by key, we need to resolve conflicting values. This is the place for `onEqual` parameter. It takes a function, which for the given `key` and its values in current and merged dictionaries, will produce an output value. - Second `Merge` overload additionally allows to supply extra parameters which may be used to map key/value pair to output value in case, when a unique dictionary entry was found on either left or right side of the operation. This would allow to construct dictionaries from scratch using any arbitrary logic, just like in case of `ToImmutableDictionary` method. - It may be possible, that the `other` dictionary could be generalized even further into a `IEnumerable>`. - Potentially, the similar set of methods could be also applied to mutable `IDictionary<,>` interface (see `Intersect` and `Except` methods on `ISet<>` interface for reference)." 23386 area-System.Collections "Tests under: System.Collections.Generic.Tests.EqualityComparerTests/NullableEquals failed with ""System.NullReferenceException""" Opened on behalf of @Jiayili1 The test `System.Collections.Generic.Tests.EqualityComparerTests/NullableEquals(left: 0, right: 128, expected: False)` has failed.

property (as a function) of a F# Record with generic union input. This used to work in ""classic"" .NET (net45) ### Details While porting [my library](https://github.com/Zaid-Ajaj/Fable.Remoting) from full classic .NET (net45) to .NET Core 2.0 I have come across a weird bug that occurs in Microsoft.CSharp when trying to invoke properties of a F# record dynamically from C# at runtime. I wrote [this static class](https://github.com/Zaid-Ajaj/Fable.Remoting/blob/master/Fable.Remoting.Reflection/FSharpRecord.cs) in C# to do this task and it worked just fine for all kinds of inputs. ```cs using System.Reflection; using Microsoft.CSharp; // etc... public static class FSharpRecord { static B Pipe(this A x, Func f) => f(x); public static dynamic Invoke(string methodName, object implementation, object arg, bool hasArg) { return implementation .GetType() .GetProperty(methodName) .GetValue(implementation, null) .Pipe((dynamic fsFunc) => hasArg ? fsFunc.Invoke((dynamic)arg) : fsFunc.Invoke(null)); } } ``` This class works very well with F# records and I have tested it before with net45 but the tests fail when the input is a generic union type from F# such as: ```fs type Maybe<'t> = | Just 't | Nothing ``` Here is my test suite from [this file](https://github.com/Zaid-Ajaj/Fable.Remoting/blob/master/Fable.Remoting.Server.Tests/ServerDynamicInvokeTests.fs#L18): Given the record type: ```fs type TestRec = { simpleMethod : string -> int listsMethod : int list -> int genericUnion: Maybe -> int } ``` And these tests (written with Expecto) ```fs let fsharpRecordTests = let invoke (methodName: string) (record: obj) (input: obj) (hasArg: bool) = FSharpRecord.Invoke(methodName, record, input, hasArg) let testRec = { genericUnion = function Just x -> x | _ -> 0 simpleMethod = fun input -> input.Length listsMethod = fun xs -> Seq.sum xs } testList ""FSharpRecord tests"" [ testCase ""Invoking listsMethod"" <| fun () -> let input = [1 .. 10] let output = invoke ""listsMethod"" testRec (box input) true equal 55 (unbox output) testCase ""Invoking simpleMethod"" <| fun () -> let input = ""hello"" let output = invoke ""simpleMethod"" testRec (box input) true equal 5 (unbox output) testCase ""Invkoing genericUnion on record dynamically works"" <| fun () -> let input = Just 5 let output = invoke ""genericUnion"" testRec (box input) true equal 5 (unbox output) ] ``` The test cases ""Invoking simpleMethod"" and ""Invoking listsMethod"" do pass but the last test case with the generic union input fails, here is the test log: ``` cmd /C dotnet Fable.Remoting.Server.Tests\bin\MCD\Release\netcoreapp2.\Fable.Remoting.Server.Tests.dll [08:02:18 INF] EXPECTO?

It would be nice if we can initialize the client with the Http version of choice once, and use it for every API that `HttpClient` provides. # Rejected API Proposal (attempt) Motivation: Change default Http protocol version to the latest supported version by default to get the best performance. ```diff public static class HttpVersion { public static readonly Version Unknown = new Version(0, 0); public static readonly Version Version10 = new Version(1, 0); public static readonly Version Version11 = new Version(1, 1); public static readonly Version Version20 = new Version(2, 0); + public static readonly Version Default = new Version(int.MaxValue, int.MaxValue); // Use the highest version that the platform supports } ``` Note: Similar to [`SecurityProtocolType.SystemDefault`](https://apisof.net/catalog/System.Net.SecurityProtocolType.SystemDefault) 23395 area-Meta "Undo ""goto return"" works-around" Issue to track following up on feedback at https://github.com/dotnet/coreclr/pull/13314#issuecomment-321586182 -- now that the JIT tries to pull early returns out of loops, find the code where `goto` has been added to work around its prior inability to do so, revert, and make sure the JIT gives the desired layout. 23396 area-System.Reflection Added GetAssemblyName API for AssemblyDefinition and AssemblyReference Also added GetAssemblyName() APIs on AssemblyReference and AssemblyDefinition This is my initial pull request.

The .NET Framework 4.7 `HttpClient/WebClient` outperforms .NET Core's `HttpClient` by ~1.5-2x in terms of how long it takes to complete a batch of _n_ requests. ### Testing The test is a console app (run in release mode on Windows 7 16GB 3.5GHz) with identical code for .NET Core/Framework that follows this sequence: 1. Create a single, shared HttpClient instance with a maximum of _n_ (for testing _n_=10,100) connections. ``` // .NET Core 2.0 var httpClient = new HttpClient(new HttpClientHandler { MaxConnectionsPerServer = 100 }); // .NET Framework 4.7 ServicePointManager.DefaultConnectionLimit = 100; var httpClient = new HttpClient(); // .NET Framework 4.7 - WebClient instance is created ONCE PER REQUEST ServicePointManager.DefaultConnectionLimit = 100; var webClient = new WebClient(); ``` 2. Start 10,000 simulataneous requests and time how long each request takes to complete + how long all take to complete. Here is code demonstrating how requests are made / timed. ``` private void RunTest(int count) { // requests is a list of Request data structures used to store individual request latency / responses var requests = Enumerable.Range(0, count).Select(j => CreateRequest(j)).ToList(); // this stopwatch is for duration of all requests var stopwatch = Stopwatch.StartNew(); // start all requests and wait for completion var requestTasks = requests.Select(MakeRequest).ToArray(); Task.WaitAll(requestTasks); stopwatch.Stop(); // total run time = stopwatch.ElapsedMilliseconds } private Task MakeRequest(Request request) { var stopwatch = Stopwatch.StartNew(); var response = await httpClient.GetStringAsync(request.Url); stopwatch.Stop(); // save request duration and response request.DurationMs = stopwatch.ElapsedMilliseconds; request.ResponseId = ParseResponse(response); } ``` I am testing against a basic python server that is well under capacity to rule out any server side bottlenecks. The server returns a simple JSON response containing an `id` field which is used to validate the HttpClient responses. ``` { ""id"": ""some_identifier"" } ``` JSON deserialization / response validation is NOT included in performance stats. ### Results These are average statistics (in milliseconds) of 5 separate runs of 10,000 requests each. It is worth mentioning that the actual time spent on each request was much less with .NET Core's HttpClient, it's just that the batch of requests takes longer to complete as a whole vs .NET Framework. | framework | total run time (ms) | avg req time (ms) | median req time (ms) | total time spent on requests (s) | |---------------|---------------------|-------------------|----------------------|----------------------------------| | .NET Core 2.0 | 5614 | 216 | 282 | 777 | | .NET 4.7 | 3055 | 1355 | 1339 | 10,585 |" 23402 area-Microsoft.CSharp Fix duplicate types exception on WinRT interfaces For certain WinRT types like `Windows.Foundation.Collections.IPropertySet`, when using the dynamic C# binder and calling a method, for example `Add(key, value)`, the binder creates the type hierarchy and tries to bind the base method. The existing code tries to bind implemented interfaces both in the AggregateType's t ype hierarchy and WinRT interfaces, and ends up with duplicates, which results in: ```Microsoft.CSharp.RuntimeBinder.RuntimeBinderException:The call is ambiguous between the following methods or properties: 'System.Collections.Generic.IDictionary.Add(string, object)' and 'System.Collections.Generic.IDictionary.Add(string, object)'``` The simple workaround for now is to use a `HashSet` to store these interfaces, so that we don't end up passing duplicates up the call chain. A smarter way of filtering out types that we know for sure are not applicable should be considered in the future.

While importing `EncryptedXml` into Mono (https://github.com/mono/mono/pull/5273), it was noticed that its following members are missing: * [The `(XmlDocument, Evidence)` constructor.](https://msdn.microsoft.com/en-us/library/kc1kt87d(v=vs.110).aspx) * [The `DocumentEvidence` property.](https://msdn.microsoft.com/en-us/library/system.security.cryptography.xml.encryptedxml.documentevidence(v=vs.110).aspx) This PR adds them. The implementation is taken from [.NET Framework](https://referencesource.microsoft.com/#System.Security/system/security/cryptography/xml/encryptedxml.cs). The behavior of the `EncryptedXmlTest.DecryptData_CipherReference_InvalidUri` test was changed. As far as I understand, both .NET Core and .NET Framework must behave the same way. According to [the documentation](https://msdn.microsoft.com/en-us/library/system.security.securitymanager.getstandardsandbox(v=vs.110).aspx), the `SecurityManager.GetStandardSandbox` must throw if the evidence is null. Previously, .NET Core wasn't throwing in this case, so this was changed as well. 23418 area-System.Collections Added Merge and Intersect methods to immutable dictionaries This PR is work in progress. I've made this as a reference point for further discussion for a new API methods proposed in #23385 : - ` IImmutableDictionary Intersect(IEnumerable> other, Func resolveValue)` - `IImmutableDictionary Merge(IEnumerable> other, Func resolveValue)` They aim to provide set-like intersection/union methods over dictionaries. Those two methods have specialized implementations for both `ImmutableDictionary` and `ImmutableSortedDictionary`, however I'm not yet much familiar with immutable collections internals. Also it would be great, if somebody could help me create some unit tests for those. 23419 area-System.Collections Proposal: ReverseComparer If you want to sort a `List` by descending, you have to create a Reverse IComparer class. My Proposal is to add a `ReverseComparer` class like System.Linq.Parallel.ReverseComparer and add extension method like ``` csharp public static IComparer Reverse(this IComparer comparer); public static IComparer Reverse(this IComparer comparer); ``` ## Usage This api is to make it simple to make a reverse comparer. ```csharp list.Sort(comparer.Reverse()); // you can use list.Sort((x,y)=>comparer.Compare(y,x)); insted var sorteddictionary = new SortedDictionary(comparer.Reverse()); //you can use (Comparer.Create((x,y)=> comprer.Compare(y,x))); ``` ## API ```csharp public class ReverseComparer: IComparer { public ReverseComparer(IComparer comparer); public int Compare(T x, T y); public static IComparer Reverse(this IComarer comparer); } ``` 23420 area-System.Data Increase code coverage from 39.1% to 50.8% on System.Data.Common.DataColumnMapping Hi, Here are some tests to increase code coverage.

However, it does not do that in .NET Core (it seems that AllowAutoRedirect is simply ignored), so I'm assuming this is a bug. Please let us know if there's a workaround.

Avoid the unnecessary intermediate allocation by using `Version.Parse` directly in the two places `Version..ctor(string)` is used in CoreFX. Also, some minor cleanup to `XslCompiledTransform` while making changes here. cc: @krwq (for System.Xml) cc: @AlexGhiondea, @joperezr (for System.Runtime.Extensions) 23426 area-System.Net HttpClient specify interface to bind to / make requests from On a machine with multiple NICs, how can i specify (if possible) which interface IP to use for making requests?

For example, we might have a cache implementation that does some cleanup or flush-to-disk after reaching some arbitrarily defined X items in the dictionary: ```cs if (map.Count > 10000) cleanup(); ``` In this use-case it doesn't really matter what the exact value of X is, and is perfectly tolerable if some race condition causes it to be inaccurate once in a while, but the action itself might be called a lot and in quick succession (maybe even in a tight loop), so the cost of the lock in `Count` is not negligible, and the developer might prefer to write `if (map.ApproximateCount> 10000) cleanup();` instead to avoid that cost. Another use-case with similar rationale behind it might be when we want to construct a list from a dictionary (or multiple dictionaries/collections), and need to come up with a reasonable estimate of the list's capacity before-hand to avoid extra copies. We could then write something like: `List list = new List(map1.ApproximateCount + map2.ApproximateCount);`, if we believe that the cost of using `Count` would be greater than the occasional non-exact list capacity. 23440 area-System.IO Investigate rel OSX ZipFile failures Some ZipFile tests are failing on OSX in rel/1.0.0 and rel/1.1.0 because they're unable to match file names to entries in the FileData class.

Similarly, `ComparerUtilities.DefaultEquals()` replaces usages of `EC.Default.Equals()`. After hours of tinkering this morning, I finally got the code in `DefaultEquals` / `FastEquals` to inline without regressing the asm for any of the test cases. That is, for well-known types it folds into a single instruction, while for other types it generates the exact same code as before. So, aside from the increased JIT time, the perf is essentially free. So far, I've modified nearly all the types in System.Collections to use this API. I also plan on doing the following before un-WIPing this PR: - [ ] Having System.Collections.{Concurrent,Immutable} and System.Linq use the API - [ ] Making sure there is no asm regression for desktop-- [it doesn't seem like it optimizes the `typeof` trick in generic methods](https://github.com/dotnet/coreclr/issues/13514#issuecomment-323987735) - [ ] Publishing perf measurements 23467 area-Infrastructure Allow build to work behind corporate proxy servers Many corporate proxies require default user credentials to be sent.

This leads to subtle bugs when switching back and forth between inputs, as a length can accidentally become an offset, or vice versa. We should remove the `public Span(T[], int)` ctor to avoid the confusion. We will still have the `public Span(T[])` ctor for cases where you want a span over the whole array, and we will still have the `public Span(T[], int, int)` ctor for cases where you want to specify the array, an offset, and a length, and for cases where you only want to specify the array and an offset, you can use `new Span(arr).Slice(offset)` without ambiguity. 23472 area-Infrastructure Add FileApiInterop.dll to uap corefx private package Porting change #23454 to release/uwp6.0 branch.

See issues https://github.com/dotnet/sdk/issues/1522 and https://github.com/dotnet/corefx/issues/23229. We're seeing multiple issues where tools in the .NET framework build pipeline attempt to load reference assemblies in an execution context (Assembly.Load, LoadFrom, LoadFile). This fails for assemblies that have the ReferenceAssemblyAttribute. Build tools should **never** attempt to load references for execution: they may be running on totally different frameworks / platforms / versions. The problem is that not all tools (especially those for desktop) follow this practice. Largely because before System.Reflection.Metadata we didn't provide a safe way for build tools to do the right thing. They had to use the COM metadata APIs, CCI, LMR, or Cecil. Given that landscape and our desire to work in as many places as possible, should we remove the ReferenceAssemblyAttribute from any assembly which would apply to desktop? /cc @nguerrera @weshaggard @jkotas 23506 area-System.Net Invalid results of the function GetAttributeFromHeader in System.Net.HttpListenerRequest "https://github.com/dotnet/corefx/blob/ff7f4ba7ab0a9f50a0e4c1d3a3195165afd96d8f/src/System.Net.HttpListener/src/System/Net/HttpListenerRequest.cs#L293 For example, for parameters headerValue = `""multipart/form-data; boundary=abc; charset=UTF-8""` (from Content-Type header) and attrName = `""boundary""` The result will be >""abc;"" instead >""abc""" 23507 area-System.IO Make DisableMediaInsertionPrompt to be private struct to match CoreLib 23512 area-Microsoft.CSharp Porting a fix for #21689 to release/2.0.0 release/2.0.0 port of #22117 (Fix bug in MS.CSharp handling non-generic classes nested in generic) Such types are still generic but don't have a tick in their name, which the name lookup expects all generic types' names to have.

However, there is currently no way to explicitly emit specific optimized sequences of code to best take advantage of the underlying hardware. For example, the `System.Math` and `System.MathF` APIs are currently implemented as FCALLs to the underlying C Runtime implementation of the corresponding method. The underlying C Runtime implementations are most frequently implemented as hand-optimized assembly or C/C++ intrinsics to ensure that they provide the best throughput possible and that they take advantage of newer instruction sets when available (`cos`/`cosf`, for example, frequently have one code path for SSE and one for FMA3). Due to these methods depending on the underlying C Runtime implementation: * We are at a significantly delayed cadence for getting bug fixes * We often have to add hacks to workaround these bugs as we find them, decreasing perf * The implementations between platforms and architectures often differ * This leads to perf differences: https://github.com/dotnet/coreclr/issues/9373 * This leads to input/output differences between Operating Systems (Windows, Linux, Mac, etc) * This leads to input/output differences between Platforms (x86, x64, ARM, etc) * Updating these methods requires modifying the runtime By providing scalar intrinsics for the Intel hardware functions it becomes much easier to implement these functions in managed code, which: * Means fewer workarounds as bugs can be fixed directly * Keeps perf is more consistent * Keeps input/output differences minimal or non-existing between operating systems * Helps keep input/output are minimal between platforms * Allows most bug fixes to be made independent of the runtime Furthermore, with the addition of #22940, it may become more pertinent to also have these scalar intrinsics to ensure that the codegen when intermixing scalar and vectorized operations remains ""optimal"" for the end-users customized/hand-optimized algorithms. ## Proposed API The current design in #22940 creates a class per instruction set and exposes methods such as `Vector128 Sse2.Sqrt(Vector128)` which corresponds to the `__m128d _mm_sqrt_pd(__m128d)` C/C++ intrinsic`. This would additionally extend the surface area to expose the scalar forms of all the instructions with the same name as the vector intrinsic, but with a `Scalar` postfix. This is required to differentiate between the vector and scalar APIs due to them taking the same types as their inputs. For example, we would expose: ```csharp public static class Sse2 { // __m128d _mm_add_sd(__m128d a, __m128d b); public static Vector128 AddScalar(Vector128 left, Vector128 right); // ... // No corresponding C/C++ intrinsic, used when upper should be taken from `value` public static Vector128 SqrtScalar(Vector128 value); // __m128d _mm_sqrt_sd(__m128d a, __m128d b) public static Vector128 SqrtScalar(Vector128 upper, Vector128 value); // ... } ``` ## Other Thoughts Most of the remaining sections (Intended Audience, Semantics and Usage, Implementation Roadmap, etc) are the same as in #22940 " 23520 area-System.Runtime Serialized Exception and AggregateException may not exchange successfully between CoreRT and CoreCLR `AggregateException` has a field `_innerExceptions` in CoreRT but `m_innerExceptions` in CoreCLR. It does not implement ISerializable so I think it will not exchange correctly. `Exception` does implement ISerializable and from eyeball it looks like the de/serialization will work although I notice CoreRT does not implement `ExceptionMethod` and `WatsonBuckets` and it does not set `RemoteStackTrace` even though CoreCLR needs that (it reads `StackTrace` but then nulls it out in `[OnDeserialized]`). Similarly `RemoteStackIndex`. 23523 area-System.Runtime Adding cross framework serialization and blob sanity check for serializable Exception types Relates to https://github.com/dotnet/corefx/issues/23520 Relates to https://github.com/dotnet/corert/pull/4377 This enables cross serialization and blob sanity checks for exception types.

The way to send custom per request headers with `HttpClient` is via `SendAsync` and adding them to the `HttpRequestMessage`. However that isn't very discoverable and is a big jump from using the convenience methods `GetAsync`, `PostAsync`, etc This can lead people to changing the `DefaultRequestHeaders` on the `HttpClient` instead: [SO](https://stackoverflow.com/a/35910012/1109918), [SO](https://stackoverflow.com/q/42156953/1109918), [SO](https://stackoverflow.com/q/10679214/1109918), etc Which is very dangerous if the `HttpClient` is used as a static; which is [also an official suggested practice](https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/calling-a-web-api-from-a-net-client) > **HttpClient** is intended to be instantiated once and re-used throughout the life of an application. Especially in server applications, creating a new **HttpClient** instance for every request will exhaust the number of sockets available under heavy loads. This will result in **SocketException** errors. And in popular blogs [""You're using HttpClient wrong and it is destabilizing your software""](https://aspnetmonsters.com/2016/08/2016-08-27-httpclientwrong/) > This is dramatic. If you have any kind of load at all you need to remember these two things: > > 1. Make your HttpClient static. > 2. Do not dispose of or wrap your HttpClient in a using unless you explicitly are looking for a particular behaviour (such as causing your services to fail). Both changing `DefaultRequestHeaders` per request and concurrently making requests from a shared `HttpClient` will end *very* badly. ## Proposal Add overloads to the convenience methods `GetAsync`, `PostAsync`, etc to allow for customer headers on a per request basis from a shared `HttpClient` ```csharp public partial class HttpClient { Task DeleteAsync(string requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task DeleteAsync(string requestUri, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task DeleteAsync(Uri requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task DeleteAsync(Uri requestUri, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task GetAsync(string requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetAsync(string requestUri, HttpRequestHeaders requestHeaders, HttpCompletionOption completionOption) { throw null; } Task GetAsync(string requestUri, HttpRequestHeaders requestHeaders, HttpCompletionOption completionOption, CancellationToken cancellationToken) { throw null; } Task GetAsync(string requestUri, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task GetAsync(Uri requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetAsync(Uri requestUri, HttpRequestHeaders requestHeaders, HttpCompletionOption completionOption) { throw null; } Task GetAsync(Uri requestUri, HttpRequestHeaders requestHeaders, HttpCompletionOption completionOption, CancellationToken cancellationToken) { throw null; } Task GetAsync(Uri requestUri, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task GetByteArrayAsync(string requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetByteArrayAsync(Uri requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetStreamAsync(string requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetStreamAsync(Uri requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetStringAsync(string requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task GetStringAsync(Uri requestUri, HttpRequestHeaders requestHeaders) { throw null; } Task PostAsync(string requestUri, HttpContent content, HttpRequestHeaders requestHeaders) { throw null; } Task PostAsync(string requestUri, HttpContent content, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task PostAsync(Uri requestUri, HttpContent content, HttpRequestHeaders requestHeaders) { throw null; } Task PostAsync(Uri requestUri, HttpContent content, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task PutAsync(string requestUri, HttpContent content, HttpRequestHeaders requestHeaders) { throw null; } Task PutAsync(string requestUri, HttpContent content, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } Task PutAsync(Uri requestUri, HttpContent content, HttpRequestHeaders requestHeaders) { throw null; } Task PutAsync(Uri requestUri, HttpContent content, HttpRequestHeaders requestHeaders, CancellationToken cancellationToken) { throw null; } } ``` ## Notes There are also suggestions [for going further for increased safety](https://twitter.com/xoofx/status/900367218806063104) > I would opt for taking headers at construction time and freeze them, or allow to pass frozen headers through a param or TLS...etc Perhaps freezing the `DefaultRequestHeaders` on first request; and throwing an `InvalidOperationException` if they are modified after the first request has been initiated? As modifying the default headers while requests are being initiated in parallel will lead to nonsensical outcome; and modifying them and submitting a request can't be an atomic operation. /cc @davidsh, @CIPop, @Priya91 @xoofx @khellang " 23545 area-System.Data Failed to load sni.dll "Posted project here: https://github.com/foxjazz/gadgetWebApi.git Created asp.net 2.0 core app with a controller that opens a connection sqlConnection. when this happens error is here but only on a 2008 r2 server the app is published to.

Since EventCounters rely on timers to periodically send callbacks, then EventCounters also are not prompt. The tests bascially set the EventCounters to fire every 100 msec and expect at least 2 timer callbacks in 700 msec, which is pretty generous. However we have a case where this fails (we only got 1). Rather than simply make the time bigger (it is already very generous), I have created another use of Timer which simply counts how many 100msec ticks go off. If THIS timer does not register enough ticks, then we don't require EventCounter to do so either.

The thing with `ICollection`, is that it doesn't inherit from `ICollection`, and there are types that inherit from `ICollection` but not from `ICollection` (for instance `HashSet`). Additionally, `ICollection` isn't co-variant, meaning not every `ICollection` is an `ICollection`, like `IEnumerable` is. I'm not arguing about this design, which is a good thing to avoid confusion and mis-adding of types. ### Motives The thing I do find annoying here, and I bump into it a lot, is the `Count` property, which is common to `ICollection` and `ICollection` and `IReadOnlyCollection`, but these interfaces don't overlap each other. Obtain a value from a generic type when the type argument is unknown at compile time is only possible with reflection. So in order to get the known size of a collection you'd have to do the following (see discussion [here](https://github.com/dotnet/corefx/pull/23664#discussion_r136200693)). And with the branching of the `TypeInfo` class, this gets even worse: ```c# //gets count if known int? GetCountIfKnown(IEnumerable collection) { if(collection is ICollection collection) return collection.Count; else { Type genericCol = value.GetType().GetTypeInfo().ImplementedInterfaces.Select(t => t.GetTypeInfo()).FirstOrDefault(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(ICollection<>)); if (genericCol != null) retun (int)genericCol.GetTypeInfo().GetProperty(""Count"").GetValue(value); } return null; } ``` As pointed out later in [comments](https://github.com/dotnet/corefx/issues/23578#issuecomment-325664702) by @NightOwl888, the `IReadOnlyCollection` interface also exposes the `Count` property, but the reasons it doesn't address my issue is: - It's generic, so when the type is unknown at compile time, we can only evaluate it using reflection - `ICollection` doesn't inherit from it. - Not all collections with known size inherit from it There are many use cases of non-generic collections I bump into, the real reason we need non-generic support, is not because their not generic, but rather because their generic argument may not be known at runtime. I can't remember all of the scenarios I've encountered this demand as they are many, but I'll name a few. - When developing general tools (i.e. XAML converters) that are supposed to eat a wide variety of value types and work differently when the value is a collection. - We need to store a collection of `ICollection`s of a variety of types. When enumerating the main collection, the count of the items can only be achieved by acquiring the collection type with reflection. ### Solution My suggestion is then, to introduce a new interface `ICountable` (or `IReadOnlyCollection` - non generic) that its contract determines that a collection has a `Count` property and exposed the collection size regardless of its item type. This interface should be implemented by (please comment if you're aware of others): - `ICollection` - `ICollection` - `IReadOnlyCollection` The new interface should have one sole task: expose a known size of a collection via a `Count` property, with disregard to the collection type (`T`), editability (`ICollection` vs `IReadOnlyCollection`), or other features. ```c# int? GetCountIfKnown(IEnumerable enumerable) => (enumerable as IReadOnlyCollection)?.Count; ``` ### Concequences - Implicit implementations of `ICollection`, `ICollection` and `IReadOnlyCollection` will have to change the pattern to `ICountable` (or if we call it `IReadOnlyCollection` or anything else). - Implementations that call the property `Count` on `ICollection` (or the others) as ""declared"", will have to switch to either calling the runtime property, or call it on `ICountable` etc. Related: https://github.com/dotnet/corefx/issues/23700." 23579 area-System.Net Netcore2.0 Unix Socket Tcp Send Big Buffer Raise Error Message too long https://github.com/caozhiyuan/DotNetty/tree/dev/examples/SocketAsyncClient https://github.com/caozhiyuan/DotNetty/tree/dev/examples/SocketAsyncServer when nioBuffers total byte size big than 344064,will raise 10040 MessageSize Error（Message Too Long） ```c# SocketError errorCode; long localWrittenBytes = this.clientSocket.Send(nioBuffers, SocketFlags.None, out errorCode); if (errorCode != SocketError.Success && errorCode != SocketError.WouldBlock) { throw new SocketException((int)errorCode); } ``` 23580 area-System.ComponentModel Tests for System.ComponentModel.DataAnnotations * Check ValidationException throws PSNE on .NET Core serialisation. * Test multiple validation errors can be returned from same call. 23581 area-System.ComponentModel Some refactoring in System.ComponentModel.DataAnnotations * Use null propagation where appropriate. * Fix parameter reference in XML documentation. * Remove unnecessary `this.` qualifications. * Properties to auto-properties where possible. * Auto-properties get-only where appropriate. * Use `GetValueOrDefault` rather than `Value` when known that `HasValue` Avoids second check. * Make field `readonly`. * Remove unused parameter on private method. * Remove `CompareAttribute.IsPublic` Unused and private. * Don't check to avoid redundant write to `LocalizableString.Value` `LocalizableString.Value` protects itself from redundant writes with its current value, so checking from the outside is wasteful. * Use expression-bodied properties and methods throughout. * Remove unused `using`s. 23582 area-System.Net HttpUtility.ParseQueryString does HTML decoding first on CoreFX, but not on NetFX "The version of `HttpUtility.ParseQueryString` in CoreFX does HTML decoding first, differing from desktop: ```C# HttpUtility.ParseQueryString(""name=value&name2=value2"").ToString() // name=value&%3bname2=value2 on Desktop // name=value&name2=value2 on CoreFX HttpUtility.ParseQueryString(""?name=valué"")[""name""] // valu on Desktop // valué on CoreFX ``` #23573 is a knock-on effect of this.

For example `Enumerable.Repeat(new Contact(), 10) will generate a single `Contact` and an iterator of 10 references to that single object. My suggestion is hereby to please introduce a new method in the `Enumerable` class, that generates a number of instances according to the desired one. ### Suggestion Please implement one of the following options: - Introduce a new method in the `Enumerable` class that generates a separate new reference type for each iteration - Add a new overload with a flag that specifies whether to activate a new one for each iteration or reuse them - Add a new overload that takes an `Action` that uses as an activation action, and is called upon each iteration - One of the above plus an `Action` where `int` is the current index. What I'm looking for is simply a shorthand for: Enumerable.Range(0, count).Select(i => new Contact { Id = i }); Looks like there is a demand for it, see [this](https://stackoverflow.com/questions/17865166/creating-a-list-filled-with-new-instances-of-an-object) and [this](https://stackoverflow.com/questions/13553022/how-can-i-use-linq-to-initialize-an-array-of-repeated-elements)) Additionally, as a syntactic sugar, please make an overload of `Enumerable.Repeat` without the [first argument](https://source.dot.net/#System.Linq/System/Linq/Repeat.cs,12), (instead, perhaps and the `where TResult: new()` constraint), and when called activate a new element of TResult without having to specify it.

It seems like all exception types should be serializable/deserializable given the fact they are the most likely to cross application boundaries, but that doesn't seem to be the case. We have a test to verify exceptions can both serialize and deserialize.

However, we can't exactly work around this by inheriting `System.Exception` since we are porting from Java and the application relies heavily on catching the right exception types to go down the correct execution path (at least not without putting in a catch block for every single one of our custom exception types that inherits `System.IO.IOException`, etc.) What I am wondering is whether or not this is a bug, whether or not we shouldn't be relying on serialization yet in .NET Standard 2.0, and if this was intentional why such an odd choice to allow serialization on some exceptions but not others was made? ### Platform Microsoft Windows [Version 10.0.15063] (c) 2017 Microsoft Corporation.

Regrettably, in Windows there is no equivalent mechanism: a pseudo shell ""command line"" must be passed as a _single string_ encoding _all_ arguments, and it is up to the _target executable itself_ to parse that line into individual arguments. The `ProcessStartInfo` class currently only supports the _Windows_ approach directly, by exposing a `string Arguments` property that expects the whole command line. **On Unix platforms, this means that even if you start out with an array of arguments, you must currently artificially assemble its elements into a single pseudo shell command line, only to have CoreFX split that back into an array of individual arguments behind the scenes** so as to be able to invoke the platform-native process-creation function, which takes an _array_ of arguments. Not only is this an unnecessary burden on the user and inefficient, it is error-prone. It is easy to accidentally assemble a command-line string that does _not_ round-trip as expected. As a real-world use case, consider the [ongoing quoting woes PowerShell experiences](https://github.com/PowerShell/PowerShell/issues/1995). At least on Unix platforms, PowerShell should be able to simply pass the arguments that are the result of _its_ parsing _as-is_ to external utilities. Having the ability to pass an _array_ of arguments would be of benefit on Windows too, as it is fair to assume that the more typical use case is to build the desired arguments as a list / array rather than to piece together a single-string command line with intricate quoting. (The latter should only be needed if you're passing an preexisting string through or if you're invoking an executable that has custom argument-parsing rules.) # Proposed API **Add a `IReadOnlyList ArgumentList` property (conceptually, an array of argument string literals) to the `ProcessStartInfo` class**, to complement the existing `string Arguments` (pseudo shell command line) property, and let each update the other lazily, on demand, when accessed: * If `.Arguments` was (last) assigned to, do the following when `.ArgumentList` is accessed: Call [`ParseArgumentsIntoList()`](https://github.com/dotnet/corefx/blob/edecb1207cbe6194cb9a9f1bc862ef8d1ebb3ef4/src/System.Diagnostics.Process/src/System/Diagnostics/Process.Unix.cs#L481), which splits the string into individual arguments based on [the rules for MS C++ programs](https://docs.microsoft.com/en-us/cpp/cpp/parsing-cpp-command-line-arguments) and return the resulting list. * If `.ArgumentList` was (last) assigned to, do the following when `.Arguments` is accessed: Synthesize the pseudo shell command line from the individual arguments and assign the result to using the above rules _in reverse_ (enclose in `""...""` if a given argument has embedded whitespace, ..., as already implemented for internal use [in `System.PasteArguments.Paste()`](https://github.com/dotnet/corefx/blob/5d3e42f831ec3d4c5964040e235824f779d5db53/src/Common/src/System/PasteArguments.cs#L16)) and return the resulting `string`. * As @TSlivede proposes, it's worth extending the conversion algorithm to also double-quote arguments that contain `'` (single quotes) lest they be interpreted as having _syntactic_ function, which to some programs they do (e.g., Ruby, Cygwin). That way, both `.Arguments` and `.ArgumentList` can be assigned to, and the respective other property contains the equivalent in terms of the official (MS C++) parsing rules. A `ProcessStartInfo` instance constructed this way can therefore be used on all supported platforms: * On Windows, pass the `.Arguments` property value to the `CreateProcess()` / `ShellExecuteEx()` Windows API functions, as before. * On Unix platforms, pass the `.ArgumentList` property value via `.ToArray()` to [`ForkAndExecProcess()`](https://github.com/dotnet/corefx/blob/edecb1207cbe6194cb9a9f1bc862ef8d1ebb3ef4/src/Common/src/Interop/Unix/System.Native/Interop.ForkAndExecProcess.cs#L15). Additionally, to complement the suggested behind-the-scenes conversion between the array form and the single-string form, **public utility methods should be implemented** that perform these conversions explicitly, on demand. @AtsushiKan proposes the following signatures: ```csharp public static IReadOnlyList SplitArguments(String commandLine) { ... } public static String CombineArguments(IReadOnlyList argumentList) { ... } ``` # Open Questions * How exactly should the existing, currently (effectively) private utility methods referenced above be surfaced publicly (namespace, class, signature)? Currently, they're in different classes, and one of them is `internal` (`System.PasteArguments`); @AtsushiKan suggests making them public methods of the `System.Diagnostics.Process` class. # Usage ```csharp // The array of arguments to pass. string[] args = { ""hello"", ""sweet world"" }; // ---- New ProcessStartInfo.ArgumentList property. // Assign it to the new .ArgumentList property of a ProcessStartInfo instance. var psi = new ProcessStartInfo(); psi.ArgumentList = args; // Accessing .Arguments now returns the pseudo shell command line that is the // equivalent of the array of arguments: // @""hello """"sweet world"""""" string pseudoShellCommandLine = psi.Arguments; // ---- New utility methods for conversion on demand. // EXACT NAMES AND SIGNATURES TBD. // Arguments array (list) -> pseudo shell command line string[] args = { ""hello"", ""sweet world"" }; string pseudoShellCommandLine = System.Diagnostics.Process.CombineArguments(args); // Pseudo shell command line -> arguments array (list) IReadOnlyList argList = System.Diagnostics.Process.SplitArguments(@""hello """"sweet world""""""); ```" 23594 area-System.Runtime Expose/test TimeSpan span-based methods Two commits: 1.

The php has already supoorted change user in mysqli: http://php.net/manual/en/mysqli.change-user.php 23599 area-System.Linq Add ParallelEnumerable.WithTaskScheduler Full .NET has internal method to do PLINQ with [custom scheduler](https://github.com/Microsoft/referencesource/blob/master/System.Core/System/Linq/ParallelEnumerable.cs#L303). Current .NET Core does not have such method in [ParallelEnumerable](https://github.com/dotnet/corefx/blob/a38c5000be0d4b98445ef43d642614d0e8d8f82d/src/System.Linq.Parallel/src/System/Linq/ParallelEnumerable.cs). Could we have `WithTaskScheduler` public in `ParallelEnumerable` or any other viable alternative? I see that [underlying classes do have task scheduler configuration build in](https://github.com/dotnet/corefx/blob/bffef76f6af208e2042a2f27bc081ee908bb390b/src/System.Linq.Parallel/src/System/Linq/Parallel/QueryOperators/QuerySettings.cs#L28). Why this is needed? We have product which did not setup default task scheduler for whole process/appdomain. So we do that that manually. I am afraid to set scheduler process/appdomain wide to avoid regression. Same time I want to use PLINQ instead of Tasks/Parallel, where PLINQ is best fit. But I cannot use PLINQ as customer scheduler is must for us. Another possible reason for such api is virtual isolation. I have witnessed that applications do more and more isolation not on process/appdomain levels, but in process via type loading and di/ioc containers. Another level of isolation could be done with parallelism, but for this all API should accept custom schedulers. 23600 area-System.Text System.Text.Encodings.Web.TextEncoder throws NRE on constructing copy ```C# TextEncoder copyFrom = null; TextEncoder copy = new TextEncoder(copyFrom); // Throws NullReferenceException ``` Should really throw `ArgumentNullException`. 23601 area-System.Text Throw ANE for null TextEncoderSettings to TextEncoderSettings ctor Fixes #23600 Also further test to bring coverage for that class up to 100%. 23602 area-System.Text System.Text.Encodings.Web.HtmlEncoder.Create wrong parameter name on exception "If the overload of `System.Text.Encodings.Web.HtmlEncoder.Create` that takes a `TextEncoderSettings` argument is called with null, the `ArgumentNullException` thrown has a `ParamName` of `""filter""` though the parameter name is `""settings""`." 23603 area-System.Text Fix System.Text.Encodings.Web.HtmlEncoder.Create ParamName on exception Change argument name of `DefaultHtmlEncoder` ctor from `filter` to `settings` to match that of only public method that directly calls it, so any `ArgumentNullException` has the correct `ParamName` property.

Will move closer to allowing the SemaphoreSlim unix solution, as well as clarity on the flow that is required. Is a first step, readside would be next and then the underlying handshake/renegotiation. Benchmarks and traces to come, but it makes the flow a lot more readable (initial indications is that the aspnet core tests are about 5% faster and with traces I hope to show that is due to lower allocations). If I had my own way I would convert the sync methods to ReadAsync().GetAwaiter().GetResult() as it is truly async in nature and by not doing that two paths need to be maintained which leads to a higher cognitive load in a security library. That however is a decision that others need to think about. Cheers Tim 23609 area-System.Security SignedXml detailed failure feedback inaccessible I've got a simple test case where I sign a bit of XML and then try to verify its signature. Verification of the signature fails - `SignedXml.CheckSignature()` returns false. The problem is that I cannot find out *why* it fails. Does it fail while getting a public key, looking up a certificate, validating the certificate, or validating the signature? Did I do something wrong during signing and there's now necessary information missing? I don't know - all I get is a simple `false` return value. Looking at the source, `SignedXml` does extensive logging via `System.Diagnostics.TraceSource`, but it hides the actual `TraceSource` as a private static member of an internal logging helper class (`SignedXmlDebugLog`), so I can't modify the source. In the full framework, I could use an app.config file to configure the `TraceSource` externally, but as far as I can tell, this isn't possible in Core. The `TraceSource` that the debug log uses is initialized to default values and never changes. There seems to be no way to get detailed feedback from this (complex and brittle) validation process. I think such feedback is needed. 23611 area-Infrastructure Remove NetFx support libs Now that we've shipped the NETStandard support package we will no longer build its content from `master`.

Todays mix of interfaces and classes has become a little disjointed. Also there is no support for AEAD style ciphers as they need the ability to provide extra authentication information. The current designs are also prone to allocation and these are hard to avoid due to the returning arrays. # Proposed API A general purpose abstract base class that will be implemented by concrete classes. This will allow for expansion and also by having a class rather than static methods we have the ability to make extension methods as well as hold state between calls. The API should allow for recycling of the class to allow for lower allocations (not needing a new instance each time, and to catch say unmanaged keys). Due to the often unmanaged nature of resources that are tracked the class should implement IDisposable ``` csharp public abstract class Cipher : IDisposable { public virtual int TagSize { get; } public virtual int IVSize { get; } public virtual int BlockSize { get; } public virtual bool SupportsAssociatedData { get; } public abstract void Init(ReadOnlySpan key, ReadOnlySpan iv); public abstract void Init(ReadOnlySpan iv); public abstract int Update(ReadOnlySpan input, Span output); public abstract int Finish(ReadOnlySpan input, Span output); public abstract void AddAssociatedData(ReadOnlySpan associatedData); public abstract int GetTag(Span span); public abstract void SetTag(ReadOnlySpan tagSpan); } ``` # Example Usage (the input/output source is a mythical span based stream like IO source) ``` csharp using (var cipher = new AesGcmCipher(bitsize: 256)) { cipher.Init(myKey, nonce); while (!inputSource.EOF) { var inputSpan = inputSource.ReadSpan(cipher.BlockSize); cipher.Update(inputSpan); outputSource.Write(inputSpan); } cipher.AddAssociatedData(extraInformation); cipher.Finish(finalBlockData); cipher.GetTag(tagData); } ``` # API Behaviour 1. If get tag is called before finish a [exception type?] should be thrown and the internal state should be set to invalid 1. If the tag is invalid on finish for decrypt it should be an exception thrown 1. Once finished is called, a call to anything other than one of the Init methods will throw 1. Once Init is called, a second call without ""finishing"" will throw 1. If the type expects an key supplied (a straight ""new'd"" up instance) if the Initial ""Init"" call only has an IV it will throw 1. If the type was generated say from a store based key and you attempt to change the key via Init and not just the IV it will throw 1. If get tag is not called before dispose or Init should an exception be thrown? To stop the user not collecting the tag by accident? Reference #7023 # Updates 1. Changed nonce to IV. 1. Added behaviour section 1. Removed the single input/output span cases from finish and update, they can just be extension methods 1.

For example, Int32 has these string-based Parse methods: ```C# public static int Parse(string s); public static int Parse(string s, NumberStyles style); public static int Parse(string s, NumberStyles style, IFormatProvider provider); public static int Parse(string s, IFormatProvider provider); ``` and I suggested (and we agreed on and we now have) adding just one span-based one to cover them all: ```C# public static int Parse(ReadOnlySpan s, NumberStyles style = NumberStyles.Integer, IFormatProvider provider = null); ``` For the most part, that’s seemed to work well, in terms of the experience I’ve had then consuming this in other code. However, it’s worked less well in my experience for TryParse. For TryParse, Int32 has: ```C# public static bool TryParse(string s, out int result); public static bool TryParse(string s, NumberStyles style, IFormatProvider provider, out int result); ``` and we’ve now added: ```C# public static bool TryParse(ReadOnlySpan s, out int result, NumberStyles style = NumberStyles.Integer, IFormatProvider provider = null); ``` The problem is in the order of the arguments. Because the optional parameters need to come at the end of the signature, the `out int result` argument is now in the middle, differing from the corresponding long overload that works with a string. When converting code from being string-based to span-based, for me at least this has been jarring and hasn’t been a pit of success. For example, let’s say you’ve got code like this: https://github.com/dotnet/corefx/blob/master/src/Common/src/Interop/Linux/procfs/Interop.ProcFsStat.cs#L133-L138 ```C# string startingString = s.Substring(start, pos); if (long.TryParse(startingString, NumberStyles.HexNumber, CultureInfo.InvariantCulture, out startingAddress)) { string endingString = s.Substring(pos + 1, end - (pos + 1)); long.TryParse(endingString, NumberStyles.HexNumber, CultureInfo.InvariantCulture, out endingAddress); } ``` It’s pretty straightforward to replace the `.Substring` with `.AsReadOnlySpan().Slice`: ```C# ReadOnlySpan startingString = s.AsReadOnlySpan().Slice(start, pos); if (long.TryParse(startingString, NumberStyles.HexNumber, CultureInfo.InvariantCulture, out startingAddress)) { ReadOnlySpan endingString = s.AsReadOnlySpan().Slice(pos + 1, end - (pos + 1)); long.TryParse(endingString, NumberStyles.HexNumber, CultureInfo.InvariantCulture, out endingAddress); } ``` but then that doesn’t compile because the arguments are in the wrong order, and the developer needs to realize the problem and take the extra step of changing the code to be: ```C# ReadOnlySpan startingString = s.AsReadOnlySpan().Slice(start, pos); if (long.TryParse(startingString, out startingAddress, NumberStyles.HexNumber, CultureInfo.InvariantCulture)) { ReadOnlySpan endingString = s.AsReadOnlySpan().Slice(pos + 1, end - (pos + 1)); long.TryParse(endingString, out endingAddress, NumberStyles.HexNumber, CultureInfo.InvariantCulture); } ``` We should back away from the optional parameters here for TryParse, and add the same set of overloads as we have for strings. In most cases, it should mean adding only one or two more methods. 23643 area-System.Console Wrong text encoding on console apps I have a console app made in dotnet core which, among other things, receive text input using Console.ReadLine.

The error is: When using a non-null Proxy, the WindowsProxyUsePolicy property must be set to WindowsProxyUsePolicy.UseCustomProxy. (Source: System.Net.Http.WinHttpHandler) My code: ```c# var binder1 = new BasicHttpBinding(); binder1.UseDefaultWebProxy = false; binder1.ProxyAddress = proxyAddress; ``` Removing these two lines (so it uses the machines default proxy settings) results in a successful web service call. From Dudod's comments in https://github.com/dotnet/wcf/issues/1592 it seems it may be related to the WinHttpHandler implementation. I'm using Visual Studio 2017 version 15.3.0, my dll is targeting netstandard2.0 and I am using version 2.0.0 of the sdk. I'm testing this code using xunit tests targeting netcoreapp2.0.

In .NET Framework networking, XML, and cryptography all live in one library (mscorlib). In .NET Core they're in three separate libraries, and making this method work requires a circle: * XML needs networking, because (even though we discourage it) DTDs can initiate downloads. * Networking needs cryptography because TLS/https have X.509 certificates. * Cryptography needs XML for ToXmlString/FromXmlString. The easiest link to snip is the ToXmlString/FromXmlString methods. Technically ToXmlString can be written without XML (like in [.NET Framework's implementation](http://referencesource.microsoft.com/#mscorlib/system/security/cryptography/rsa.cs,fd15a0bacd426550), but FromXmlString requires an XML parser. My recommendation would be to make a `public static string ToXmlString(this RSAParameters rsaParameters)` method, and a `public static RSAParameters FromXmlString(string xml)` method; borrowing from NetFx and [CoreFx's SignedXml](https://github.com/dotnet/corefx/blob/c88064e2054fca0789511410260906ff5ff0468d/src/System.Security.Cryptography.Xml/src/System/Security/Cryptography/Xml/RSAKeyValue.cs); and to ultimately try moving off of the XML representations. --- @myloveCc commented on [Mon Aug 21 2017](https://github.com/dotnet/core/issues/874#issuecomment-323894072) ### This feature is not difficult, and I have been achieved in my project。 ```csharp using System; using System.Security.Cryptography; using System.Xml; using Newtonsoft.Json; using NETCore.Encrypt.Shared; using NETCore.Encrypt.Internal; namespace NETCore.Encrypt.Extensions.Internal { internal static class RSAKeyExtensions { #region JSON internal static void FromJsonString(this RSA rsa, string jsonString) { Check.Argument.IsNotEmpty(jsonString, nameof(jsonString)); try { var paramsJson = JsonConvert.DeserializeObject(jsonString); RSAParameters parameters = new RSAParameters(); parameters.Modulus = paramsJson.Modulus != null ?

[ClassLibraryVer2.zip](https://github.com/dotnet/corefx/files/1264804/ClassLibraryVer2.zip) [EDIT] Fix code formatting, add C# syntax by @karelz" 23689 area-System.Runtime Invariant Arrays "# Rationale and Proposed Usage .NET arrays are covariant. These leads to many complexities in the implementation of the runtime for dealing with checking if assignments to the array are valid. For example, ```csharp object [] a = ...; //A a[1]= ""hello""; //B ``` The assignment labelled `//B` must check if the `a` allows `string`s to be stored in it. If the initialisation, had been: ```csharp object [] a = new Node[10]; ``` this would raise an exception at `//B`. There are clever/ugly workarounds to remove the runtime type checks, such as https://codeblog.jonskeet.uk/2013/06/22/array-covariance-not-just-ugly-but-slow-too/. But they do not provide nice interop as moving between covariant arrays and invariant arrays using this approach requires coping. Generics negates many of the reasons for covariant subtyping on arrays. Let's add arrays that are invariantly typed, and thus do not require type checks for assignments. This proposal is to wrap standard covariant arrays with a generic struct to make its use invariantly typed, and thus enable optimization at the runtime level. If we had ```csharp InvariantArray a = new InvariantArray(10); ``` We would simply not be allowed to cast it to a different type as generic parameters to classes and structs are invariant with respect to subtyping. I think an initially beneficiary of this addition would be `System.Collections.Generic.List`, where this is used to store lots of objects the runtime type checking can be noticeable. # Proposed API ```csharp public struct InvariantArray { public InvariantArray(T[] array) {} public InvariantArray(int length) {} public ref T this[int index] { get } public int Length { get; } public T[] AsArray() { return null; } public static implicit operator T[](InvariantArray ia) { return null; } public static void Copy(InvariantArray dst, U[] src) where U : S {} /// Other things from ArrayNative } ``` This should be expanded to cover most of the things in System.Array. # Implementation sketch I believe this could be implemented using similar tricks to those used in `Span`. ```csharp public struct InvariantArray { private T[] inner; public InvariantArray(T[] array) { if (array.GetType() == typeof(T[])) { inner = array; } else { throw new Exception(); } } public InvariantArray(int length) { inner = new T[length]; } public ref T this[int index] { get { // Replace with something like the following unverifiable code: // ldloc inner // ldloc index // readonly ldelema T return ref inner[index]; } } public int Length => inner.Length; public T[] AsArray() { return inner; } public static implicit operator T[](InvariantArray ia) { return ia.AsArray(); } public static void Copy(InvariantArray dst, U[] src) where U : S { // Implement array copy without requiring type checking } /// Other things from ArrayNative } ``` * This could be initially implemented as an internal struct inside CoreCLR, where a few collections could be ported to use it. Most notably `System.Collections.Generic.List`. This could demonstrate the performance benefits. * There may need to be an additional Jit helper to implement the index property efficiently, but I believe this may just work with unsafe IL. So it could be possible to prototype on Corefxlab as was done with Span. * This approach would allow zero allocation interop with existing array code, where covariant subtyping has not be used. It is wrapping the covariant array, rather than making an internal wrapper, hence the private field can be returned to get a standard array. # Issues * The API needs fleshing out to reach parity with System.Array, but I wanted to gauge if invariant arrays might be taken before doing that work.

Also the asserts caught the fact that the logic was a little odd. We don't need to resize the buffer anymore therefore we don't have to call the ""ensureinternalbuffersize"" on each read (for the header and the frame). So I have removed that, renamed to ""ResetReadBuffer"". Removed one of the extra checks on the if statement for ""if buffercount > 0 && bufferoffset >0"". So this has the buffercount removed and an assert added to make sure we only ever get here if the buffer is null or if it has data (if it doesn't have data it should be released). Finally I added an extra assert to double check there are no decrypted bytes left. Using @geoffkizer benchmark on Azure windows 4 cores I see no difference in the 256 byte test a slight uptick in the bigger buffer but nothing to write home about. " 23699 area-Infrastructure Generic linux-x64 RID for supported distros prevents shipping native dependencies in package I have a NuGet [package](https://github.com/libgit2/libgit2sharp.nativebinaries) that needs to ship a native library via the `runtimes//native` mechanism, and I need to vary the library by linux distro due to the dependencies it has, OpenSSL being the primary one. I want to be able to run on all of the supported linux distros listed [here](https://github.com/dotnet/core/blob/master/release-notes/2.0/2.0-supported-os.md), but while testing them, I've noticed that when running `dotnet --info`, some of them show a specific RID, while others just have `linux-x64` listed as the RID. This makes it impossible to ensure the correct version of the library will be chosen. If I understand the dotnet CLI code correctly, it appears that the reason some of them are falling back to the generic RID is because the [runtime.json](https://github.com/dotnet/corefx/blob/master/pkg/Microsoft.NETCore.Platforms/runtime.json) file hasn't been updated for them. Here is the list of distros I have tested so far, and the RIDs that are displayed via `dotnet --info`: - CentOS 7 (centos.7-x64) - Fedora 25 (fedora.25-x64) - Fedora 26 (fedora.26-x64) - Debian 9 (linux-x64) - Ubuntu 14.04 (ubuntu.14.04-x64) - Ubuntu 16.04 (ubuntu.16.04-x64) - Ubuntu 17.04 (linux-x64) - Linux Mint 18.2 (linux-x64) - openSUSE 42.2 (linux-x64) Was this just an oversight, or is this an intentional change to stop updating this file? If it was intentional, can you explain the reasoning? I can't just ship a single library using the `linux-x64` RID because, for example, I need to compile a separate library for Debian and openSUSE. Right now, it appears that I don't have a way to do that. 23701 area-System.Memory Adding Memory, OwnedMemory, MemoryHandle, and IRetainable & Tests ~The CI will be green after the corresponding PR in coreclr gets merged: https://github.com/dotnet/coreclr/pull/13583~ [Done] ~**In Progress:** Working on adding tests (including those from corefxlab - https://github.com/dotnet/corefxlab/tree/master/tests/System.Buffers.Primitives.Tests).~ [Done] Part of https://github.com/dotnet/corefxlab/issues/1711 Adding the following types: - Memory\ - ReadOnlyMemory\ - OwnedMemory\ - MemoryHandle - IRetainable +Added Unit Tests.

[EDIT] Add C# syntax highlight by @karelz 23707 area-System.Console "System.Console should support ""Indentation Levels""" # Rationale It is often desired to print text that is properly indented to make it easy to read. However, in order to track indentation across method calls you have to either implement some wrapper class or pass the indentation level around. As such, `System.Console` should be extended to natively support indentation levels in a similar manner to `Sytem.Diagnostics.Debug` # Proposal `System.Console` should be extended to support the following APIs: ```csharp public static partial class Console { // The indentation character, defaults to ' ' (space) public static char IndentChar { get; set; } // The indentation level, defaults to and will not decrease below 0 public static int IndentLevel { get; set; } // The number of times `IndentChar` is repeated per `IndentLevel`, defaults to 4 public static int IndentSize { get; set; } // Increases `IndentLevel` by one public static void Indent(); // Decreases `IdentLevel` by one public static void Unindent(); } ``` Then, there are two sub-proposals: ## Proposal A Additionally expose a `public static void WriteIndented()` and `public static void WriteLineIndented()`, each with all of the corresponding overloads that `Console.Write` and `Console.WriteLine` have. ## Proposal B `System.Console` should internally track when the last `WriteLine` occurred and only prefix the indentation on the next `Write` or `WriteLine`. This may end up being confusing to some users initially, but reduces the overall new APIs considerably. 23708 area-Meta Add T4 support There is no any code generation solution except of Razor, but it's coupled with web context.

I used a single struct for the write side as that way I really only need a single pointer in the sync case and a pointer for the sslState and the cancellation token on the async side. It also means I don't have to drag that token around but get cancellation :) 23716 area-System.Threading Proposal: Asynchronously cancel a CancellationTokenSource "## **Proposal**: Add a way to asynchronously cancel a CancellationTokenSource I would like to suggest adding a method to CancellationTokenSource: ```C# public Task CancelAsync() ``` The method would work like Cancel, with a difference: - If no callback is registered, then the method processes synchronously and returns a completed task - If callbacks are registered, then a task is created and returned. That task will execute the callbacks and propagate the exceptions if any (just like Cancel) Alternatively, it could just be fire-and-forget: ```C# public void CancelAsync() ``` ## **Use case:** Whenever a CancellationTokenSource is cancelled, all registration callbacks are executed synchronously. While this is OK in most cases, I ran into the following scenario: - I have a long-running thread that can't afford to be held for a long time. This thread is in charge of cancelling the token (among other things). The thread is part of a framework. - The CancellationToken is handed to client code, over which I have no control. So I can't make sure that all callbacks can execute in a short time My problem is: in this scenario, how to guarantee that the client code won't ever block my thread for a significant amount of time? The most obvious solution is to call Cancel in another thread: ```C# Task.Run(cts.Cancel); ``` This would work. However, I would end up queuing work to the threadpool everytime I cancel a token, even though most of the tokens won't have a callback registered. It feels wrong having to add a cost to the 99% case to handle the 1%. The ""CancelAsync"" method can't be implemented from outside: - To the best of my knowledge, there is no way to know whether a callback is registered on a CancellationToken - Even if there was, there would still be a race condition between the registration and the check I don't see any major obstacle to implementation, and I think it can be done without adding an additional field to the class. That said, I'm aware of how specific is the scenario I described, and I don't know if many applications would benefit from this. *** ## Past discussion This was moved from https://github.com/dotnet/coreclr/issues/13494 Copy of the discussion: *** #### davidfowl This is similar to dotnet/corefx#14903 (but for the actual cancellation call, not dispose). I think you need to be clear if you want to > The ""CancelAsync"" method can't be implemented from outside Sure it can be. See http://referencesource.microsoft.com/#System.Web/Util/CancellationTokenHelper.cs,cbfb354e962dfb2a for an example of how it could be done. There are some questions I have based on this request - Do you want the ability to wait on the callbacks? - Do you want wait on async callbacks? That is, if the user code you were calling was itself async, would you want to await that? *** #### kevingosse > Sure it can be. See http://referencesource.microsoft.com/#System.Web/Util/CancellationTokenHelper.cs,cbfb354e962dfb2a for an example of how it could be done. If I understand this code correctly, it always uses the threadpool to call `Cancel`. I was thinking of a way to use the threadpool only if there is a callback registered, and otherwise execute the call inline. The rationale being that in most cases there will be no callback (this is true for the codebase I work on, I'm not sure how representative it is). > Do you want the ability to wait on the callbacks? I don't need it in my scenario, that's why I also suggested the fire-and-forget version. In fact, I was first thinking of a `Cancel(bool executeCallbacksAsynchronously)` overload, but that's not possible because there's already a `Cancel(bool throwOnFirstException)`. Then I thought of `CancelAsync`. I'm not sure the task would actually be useful to anybody. > Do you want wait on async callbacks? That is, if the user code you were calling was itself async, would you want to await that? Same answer as above.

CoreRT is well positioned to do this. ## Rationale ### Symmetry These properties exist on `TypeInfo` (as `GenericTypeArguments` and `GenericTypeParameters`). It is inconsistent for them to be missing on `MethodBase` With this addition, the api space would look like this: | Type/TypeInfo | MethodBase/MethodInto | | ---- | ---- | | IsGenericType | IsGenericMethod | | IsGenericTypeDefinition | IsGenericMethodDefinition | | GetGenericArguments | GetGenericArguments | | GetGenericTypeDefinition | GetGenericMethodDefinition | | MakeGenericType | MakeGenericMethod | | IsConstructedGenericType | IsConstructedGenericMethod | | ContainsGenericParameters | ContainsGenericParameters | | GenericTypeArguments | GenericMethodArguments [new] | | GenericTypeParameters | GenericMethodParameters [new] | @AtsushiKan > ### GetGenericArguments() is a code smell > Generic parameters and generic arguments are different things. The former are the ""type formals"" declared by the generic method definition. The latter are the actual (usually closed) types used to create an instantiation of the generic method definition. The 2.0 `GetGenericArguments()` api conflates the two, and while it's not the end of the world, some developers prefer to be explicit about their intentions. @kingces95 > ### GetGenericArguments() smells of roses > See [comment](https://github.com/dotnet/corefx/issues/23741#issuecomment-326705519) ## Why on MethodBase rather than MethodInfo The existing pattern in Reflection is to put apis pertaining to generics on `MethodBase` **unless** the api returns a method, in which case, it lives on `MethodInfo` so that the caller receives a `MethodInfo` without casting. Should .NET ever decide to support generic constructors, this bit of future proofing will pay off - in any case, it costs next to nothing to put it on `MethodBase`. The following apis already exist on `MethodBase`. - IsGenericMethodDefinition - IsConstructedGenericMethod - IsGenericMethod - GetGenericArguments ## Naming: GenericMethodParameters or GenericTypeParameters? While a case could be made that the word ""Type"" refers to the fact that generic parameters are ""**type** variables"", we did just introduce a new api named `Type.MakeGenericMethodParameter()`. So I'm inclined to roll with the ""Method"" names." 23742 area-System.Security WindowsIdentity ctor should pass authType to base This constructor passes null to base, should pass authType https://github.com/dotnet/corefx/blob/master/src/System.Security.Principal.Windows/src/System/Security/Principal/WindowsIdentity.cs#L202 23743 area-Infrastructure How can we maintain library packages for things that also ship in framework packages? "See https://github.com/dotnet/corefx/issues/23656, https://github.com/dotnet/corefx/pull/23719#issuecomment-326450314, and https://github.com/dotnet/corefx/commit/75962dae7f338445b57d7d276d018774e1dd2e46. Whenever we wish to expose portable surface area for a library we must do so through a package. If that library is also *inbox* in the framework the framework will carry an optimized version of the library that should take precedence. In all cases the library does not need to follow the netstandard rules (new API can only be in a new NETStandard version), since it is not part of netstandard. 1. In some cases the library can deliver its implementation completely out of band to all frameworks, so the library will want to add new API in a new package and make that API available to all platforms supporting some low version of netstandard say `netstandard1.1`. It needs to do this without regressing the inbox implementations on existing frameworks, and also without dropping support for those frameworks or causing missing member/type exceptions or loader exceptions. Examples of this sort of library are System.Collections.Immutable, System.Buffers, and System.Memory. The latter two are interesting in that they are coupled to the NETCore runtime and must preserve that implementation. 2. In other cases the library cannot deliver new implementation out of band to some frameworks: for example if the library is exposing types that already exist in desktop and we do not wish to (or cannot) deliver a replacement library out of band. In this case the library cannot add API to existing netstandard versions because those imply a version of desktop which will not have the new API. In these cases we should freeze the API and the assembly version, and ideally not even rebuild the library unless it contains actual code. We should also ensure our build system leads folks into this path so that we don't accidentally break these rules. Examples of this sort of library are Microsoft.CSharp and System.IO.Ports. We can refer to these two cases as ""OOB"" libraries and ""Anchored"" libraries for the purpose of this discussion. /cc @weshaggard @terrajobst @Petermarcu " 23744 area-System.Net release/2.0: Fix IPv6 address parsing when last number is too long Port https://github.com/dotnet/corefx/pull/23712 to release/2.0 (just the relevant commits). 23745 area-System.Net System.Net.Http.CurlException: Server returned nothing (no headers, no data) "Hi there, I'm getting an error `System.Net.Http.CurlException: Server returned nothing (no headers, no data)` when calling a https endpoint in .NET Core 1.1.2 only on Docker Container.

Rename existing Windows code to ""Icon.Windows.cs"". * These files are still separate for now, and code isn't being shared. It is likely that we could share a lot more of the code if we just made a fully-managed version. `.ico` isn't the most complicated format in the world; we could just create our own managed parser and use it everywhere. Icon.Unix.cs already has quite a bit of platform-agnostic logic like that, but it is not very robust. If we did this, we could get 100% behavior compat. * Add several corrections to the Unix implementation, mainly around argument validation and exception types. * Re-enable several test cases which were either fixed by the above bullet, or were fixed at some previous time (there were a few that just passed without me fixing anything). @qmfrederik @hughbe Compat notes from this work: # Icon * Icon(Stream, int, int) constructor does not work correctly if you specify a size which does not match the true size of the Icon in the stream.

Windows gracefully handles invalid handles, but libgdiplus may crash or otherwise behave poorly. * Icon.Dispose, when called on an Icon created via Icon.ExtractAssociatedIcon, does not destroy the underlying handle. * Icon.ExtractAssociatedIcon does not return a null Icon when passed invalid parameters. It will throw a FileNotFoundException instead. * Icon.ExtractAssociatedIcon may throw a FileNotFoundException when given an invalid path, rather than an ArgumentException. * Icon.Save may throw a NullReferenceException instead of an ArgumentNullException when passed a null stream. * Icon.Save may throw an ArgumentException rather than an ObjectDisposedException if it is given a Closed or non-writable Stream." 23748 area-Meta Don't directly throw Exception When looking at https://github.com/Microsoft/dotnet/issues/471, I noticed that the thrown exception is `Exception`, not a type derived from `Exception`.

As such here are some suggested scenarios: **All Platforms** Create/Delete a directory that is 10 & 100 levels deep **Windows Only** Create/Delete a directory that is 1000 levels deep Creation and deletion should be separate tests. Call Create / Delete on a simple directory to ensure the code has been compiled before doing the core of the test. Tests should be in the performance test project in System.IO.FileSystem. 23762 area-System.Reflection Add GenericTypeParameters to Type # Proposed Additions ```` class Type { // implementation provided by TypeInfo override public virtual Type[] GenericTypeParameters => throw new NotImplementedException() } ```` # Rationale ## Unified Metadata/Runtime Type representation `Type.GenericTypeArguments` and `TypeInfo.GenericTypeParameters` were introduced during an effort to split `Type` into a runtime representation (`Type`) and a metadata representation (`TypeInfo`). In such a world, a type's generic arguments belonged on the runtime representation while a type's generic parameters belonged on the metadata representation. Hence, `GenericTypeArguments` was declared on `Type` and `GenericTypeParameters` on `TypeInfo`. Alas, the cleaving type into runtime/metadata representations didn't take root (see https://github.com/dotnet/coreclr/issues/13714#issuecomment-326300477), `TypeInfo` was deprecated (to the extent possible), and Type's original unified abstraction restored for the .NET Standard 2.0 release. In this new world, the metadata and runtime abstractions live next to each other. So `GenericTypeParameters`, the metadata representation, belongs next to it's runtime counterpart, `GenericTypeArguments`. ## Symmetry The 2.0 generic API was symmetric between `Type` and `MethodInfo` (see below). If we desire to maintain that symmetry then if/when `GenericMethodParameters` is added to `MethodBase` (see https://github.com/dotnet/corefx/issues/23741) `GenericTypeParameters` will need to be declared on `Type`. | Type | TypeInfo | MethodInfo | | ---- | ---- | ---- | | IsGenericType | | IsGenericMethod | | IsGenericTypeDefinition | | IsGenericMethodDefinition | | GetGenericArguments | | GetGenericArguments | | GetGenericTypeDefinition | | GetGenericMethodDefinition | | MakeGenericType | | MakeGenericMethod | | IsConstructedGenericType | | IsConstructedGenericMethod | | ContainsGenericParameters | | ContainsGenericParameters | | GenericTypeArguments | | GenericMethodArguments [new] | | GenericTypeParameters [new] | GenericTypeParameters | GenericMethodParameters [new] | 23763 area-System.Reflection Add GetGenericMethodDefinition and MakeGenericMethod to MethodBase # Proposed Additions ```` class MethodBase { public virtual MethodBase MakeGenericMethod(params Type[] typeArguments) => (this as MethodInfo)?.MakeGenericMethod(typeArguments) ?? throw new InvalidOperationException(); public virtual MethodBase GetGenericMethodDefinition() => (this as MethodInfo)?.GetGenericMethodDefinition() ?? throw new InvalidOperationException(); } ```` # Proposed Modifications These virtuals need to be made `new virtual`: ```` class MethodInfo { public new virtual MethodInfo MakeGenericMethod(params Type[] typeArguments) { ... } public new virtual MethodInfo GetGenericMethodDefinition() { ... } } ```` # Rationale ## Complete The Move Originally, generic APIs for methods were all added to `MethodInfo` as opposed to `MethodBase`. Subsequently, many, but not all of, the generic APIs on `MethodInfo` have been moved to `MethodBase`. We should complete the move for the same reason the move was initiated, whatever that was. ## Symmetry with `Type` If we wish to maintain the same symmetry in generic functionality that exists between `Type` and `MethodInfo` for `Type` and `MethodBase` then we need to add `MakeGenericMethod` and `GetGenericMethodDefinition` to `MethodBase`: | TypeInfo | MethodInfo | MethodBase | | ---- | ---- | ---- | | IsGenericType | IsGenericMethod | IsGenericMethod | | IsGenericTypeDefinition| IsGenericMethodDefinition | IsGenericMethodDefinition | | GetGenericArguments | GetGenericArguments | GetGenericArguments | | GetGenericTypeDefinition | GetGenericMethodDefinition | GetGenericMethodDefinition [new] | | MakeGenericType | MakeGenericMethod | MakeGenericMethod [new] | | IsConstructedGenericType | IsConstructedGenericMethod | IsConstructedGenericMethod | | ContainsGenericParameters | ContainsGenericParameters | ContainsGenericParameters | | GenericTypeArguments | GenericMethodArguments† | GenericMethodArguments† | | GenericTypeParameters‡ | GenericMethodParameters† | GenericMethodParameters† | †See #23741 ‡See #23762 ## Ease Of Use Algorithms are forced to cast to `MethodInfo` because some functionality, like `GetGenericTypeDefinition()`, is only available there. That might have been palatable when there was some reason, some invariant, like _functionality that doesn't exist on constructors lives on `MethodInfo`_ justified that design. But that invariant no longer exists (and good riddance IMHO!) so the cast just feels unnecessary. Moving the functionality down to `MethodBase` removes the need for the cast: ```` if (methodBase.IsGenericMethodDefinition) { var methodDefinition = ((MethodInfo)methodBase).GetGenericMethodDefinition(); // ... do something with methodDefinition } ```` could instead be ```` if (methodBase.IsGenericMethodDefinition) { var methodDefinition = methodBase.GetGenericMethodDefinition(); // ... do something with methodDefinition } ```` # New Virtuals on `MethodInfo` The existing methods on `MethodInfo` cannot directly override the new additions to `MethodBase` as the former return `MethodInfo` and the latter (should) return `MethodBase`. As such, the existing virtual methods need a new vtable slot. Hence the `new virtual`. While there may be objection to exposing `new virtual` methods, in practice, derivation of the reflection API is rare, and those that do derive tend to derive from `ConstructorInfo` and `MethodInfo` and not from `MethodBase` (e.g. `Reflection.Emit`). For those unicorns that did derive from `MethodBase`, they can still make due. But there is no need to go into those weeds. Unless, that is, someone can think of a customer doing this and suggest why they might not like the `new virtuals`. 23764 area-Infrastructure Building with local CoreFx build.

What I found is there was a lot of allocations on windows and a few on Linux. The windows ones I tracked down to the fact that even though the header/trailer could not be any bigger than 32 bytes SChannel claimed it needed more space. So I have changed the calculation instead to use the StreamSizes that we have (from Linux/OSX they are fixed from SChannel it is retrieved from the API for that connection based on it's requirements/session ciphers etc). This means we always now have the correct size on windows. So I could remove the allocations and the refs. I put in some Debug.Asserts to replace the code that checked the size and allocated. Onto Linux. Currently we had zero for Headers + Trailers and just a fixed MaxMessageSize. The message size is currently set to 32k. Which the description even says is arbitrary. As the max framesize for TLS is 16k if we set this to 32k we could need to output 16k * 2 + Overhead * 2. This means we can allocate in Linux/OSX whenever we go over the 16k boundary. As the frames are independent and it's not a Kernel call just native interop I have changed the this to 16k (reduces the buffer sizes in OpenSSL as well because it has to buffer the first completed frame). Next I added the 32byte overhead to the header to work with the new flow of sizes above. Last thing I fixed is the calculation of the ""max data"" we can send. Currently we are taking the max message size and subtracting the Head and Trailer. This is not what the API says for SChannel from my understanding and certainly isn't the logic from OpenSsl. > The length of the SecBuffer structure that contains the message must be no greater than cbMaximumMessage, which is obtained from the QueryContextAttributes (Schannel) (SECPKG_ATTR_STREAM_SIZES) function. However our data is the only thing that goes into that buffer there are separate buffers for the header and trailer so the max is the max. Once this has been done I did some testing with your tool @geoffkizer and there was pretty much no difference (it's only allocations) but I could see a drop in allocations on large scale stress tests :) " 23774 area-Infrastructure Building on Server Core According to this (https://github.com/dotnet/corefx/blob/master/Documentation/building/windows-instructions.md), building requires VS 2015 or 2017 installed. And the build script actually stops if they are not found. Then, according to this (https://www.visualstudio.com/en-us/productinfo/vs2017-system-requirements-vs), VS 2017 can't be installed on Windows Server Core (or can it?). Does this mean, we can't build dotnet on a Server Core?

Now, I will be the first to admit I don't exactly know how the deflate algorithm works. I was just curious of the reasoning behind that, since it is already memory-backed, and surely it should be easy enough to implement forward-seeking, by just quickly glancing at the current implementation. `SeekOrigin.End` may become problematic with `StreamContent.ReadOnlyStream` in regards to the fact that it does not expose the complete amount of bytes returned by the server, or would do so in an unusual way (regarding the point above).~ >Removed because actual code suggests it works a little differently.

Now ideally RIDs would have more strongly-typed semantics that have continuous (eg: version) or discrete (eg: architecture) values, along with relationships and precedence between them. Today we handle these by convention. At runtime the RID is just an opaque string that's related to other opaque strings. We should create a smaller representation of the RID graph and codify all of our conventions into a some code generation task. For example: OSFamily : linux Parent OSFamily: unix Versions: none Architectures: x64, x86, arm, armel, arm64 Additional qualifiers: none OSFamily : rhel Parent OSFamily: linux Versions: 6, 7, 7.0, 7.1, 7.2, 7.3, 7.4 Architectures: x64 Additional qualifiers: none We can also have a pass-through that merges runtime.json fragments for things we don't want to represent with a generator. Given this smaller set of information we should be able to generate the same RID graph we have today but in a less-error prone way. /cc @Petermarcu 23808 area-System.Runtime Fixing uap serialization errors for exceptions Fixes https://github.com/dotnet/corefx/issues/23547 Exceptions are reflection blocked in uapaot. 23809 area-System.Memory ReadOnlySpan and Span must be `readonly` structs.

The loop in Read currently looks like this: ```C# int n = 0; do { int ch = Read(); if (ch == -1) break; buffer[index + n++] = (char)ch; } while (n < count); return n; ``` It'd be better as something like: ```C# int n; for (n = 0; n < count; n++) { int ch = Read(); if (ch == -1) break; buffer[index + n] = (char)ch; } return n; ``` 23812 area-System.Net HttpClient virtual SendAsync is not properly called HttpClient has several overloads of SendAsync. Only the one that accepts a request and cancellation token is marked virtual. Looking at the implementations they all call the version that accepts the request, option and cancellation token. Inside this method it ultimately calls the SendAsync version that accepts a request and cancellation token but from the base class. The net result is that deriving from HttpClient and overriding the only virtual implementation of SendAsync doesn't impact anything unless you happen to call the version that accepts the given parameters. HttpClient should have an overload that can be called to hook into all the methods to allow pre/post request processing. Alternatively the existing implementation should be adjusted such that all the overloads eventually call the overridable implementation that then defers to the base implementation. ```public class MyHttpClient : HttpClient { public override Task SendAsync ( HttpRequestMessage request, CancellationToken cancellationToken ) { //Will never be called unless code explicitly calls this override return base.SendAsync(request, cancellationToken); } } ``` 23813 area-Infrastructure Update CoreClr, CoreFx to , servicing-25713-01, respectively (release/1.1.0) 23814 area-Infrastructure Updating CoreFx dependencies to servicing-25705-01 23815 area-System.Runtime List.Reverse should not call Array.Reverse, or add Array.Reverse method and call it.

CC @wfurt @stephentoub 23827 area-System.Net System.Net.Http httpClient ServerCertificateCustomValidationCallback does not include the intermediate certificates provided by the server "When we assign a callback to ServerCertificateCustomValidationCallback (SCCVC) (tested on Win7/Win8.1,) the passed ""chain"" arg only includes the server certificate but no intermediate certs passed by the server. The ""chain"" only has multiple ChainElements if the server cert is signed by a certificate, intermediate or root, that exists in the local store. If we have a cert signed by an intermediate CA and that cert is chained by the server, even if that CA cert is in turn signed by a root/intermediate CA that exists in the store, the chain will not include any of the intermediate certificates, and will show just the server certificate. In such a case where the root cert exists in the store and the intermediate cert is chained by the HTTPS server, the request will go through successfully when no callback is defined, yet show up in the callback with ChainElements.Count == 1 and SslPolicyErrors != none; which some might find a smidge ironic. The following are the current behaviors and the corresponding behavior in the ServerCertificateValidationCallback (SCVC) in .NET Framework which I assume should be the expected behavior here. 1) When the server passes a certificate chain and a given certificate is _different_ to the one in the store for the same CN/SAN, SCCVC gets the store cert, while SCVC (expected) gets the one passed by the server. 2) When the server passes a certificate chain which does not conflict with the store, SCCVC does not get any of the certificates passed to ""chain"" other than the server cert itself. Expected behavior per SCVC is to have the server intermediate certs passed along and ADDITIONAL certs, only if the final cert is not self-signed, added to the chain where appropriate. This is preventing us from using httpClient in production. We have our certs signed by an intermediate CA which we cannot install on target systems' local cert stores. Furthermore, we use an internal root CA for testing and we would prefer to compare the CA cert to the final cert in the chain in the validation callback, rather than installing and re-installing certs as test CAs pop in and out of existence." 23828 area-System.Threading Add CancellationTokenRegistration.Token property When registering with a CancellationToken, a common pattern is to then store the resulting CancellationTokenRegistration onto some object for later disposal when the associated asynchronous operation completes. It's also common to store the original CancellationToken, so that it can, for example, be passed to TaskCompletionSource.TrySetCanceled. But having to store the CancellationToken in addition to the CancellationTokenRegistration should be unnecessary, as the registration already knows with which CancellationToken it's associated... it just doesn't expose that information. We should expose it. ```C# public struct CancellationTokenRegistration { public CancellationToken Token { get; } ... } ``` This property now exists, it's just internal: https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Threading/CancellationTokenRegistration.cs#L44 We should simply make it public. This will allow us to shrink by a reference-sized field several objects that store the CT in addition to the CTR. 23829 area-System.Net Disable default proxy test on Desktop HttpClient test `ProxyExplicitlyProvided_DefaultCredentials_Ignored` has started failing on Desktop due to build system changes. Disabling for now. #23702 23830 area-Infrastructure [Release/2.0.0] Reduce desktop targeted reference assemblies in 2.0 release See https://github.com/dotnet/corefx/issues/23505. The use of reference assemblies in 2.0 for desktop-targeted packages and netstandard support targets has resulted in a number of tooling issues. To help relieve these, we can dial back the number of reference assemblies we use. 1. Don't use reference assemblies at all for the support package / targets. - https://github.com/dotnet/corefx/pull/23711 - Will need to be ingested into SDK 2. For packages which have reference facades which are full facades, don't set the reference assembly bit. - https://github.com/dotnet/buildtools/pull/1663 - Needs to be ported to release/2.0.0 - The following packages will benefit from this: - Microsoft.Win32.Registry - System.CodeDom - System.ComponentModel.Annotations - System.Configuration.ConfigurationManager - System.Data.SqlClient - System.IO.Packaging - System.IO.Ports - System.Security.AccessControl - System.Security.Cryptography.Cng - for all but net461 see below - System.Security.Cryptography.Pkcs - System.Security.Cryptography.ProtectedData - System.Security.Cryptography.Xml - System.Security.Principal.Windows - System.ServiceProcess.ServiceController - System.Threading.Tasks.Extensions 3. For the remaining packages, consider excluding the desktop reference and instead using the implementation assembly as the reference (as we did in 1.x). These are the packages we shipped in 2.0 that contained reference assemblies with typedefs for desktop: - System.Numerics.Vectors - System.IO.FileSystem.AccessControl - System.IO.Pipes.AccessControl - System.Reflection.TypeExtensions - System.Security.Cryptography.Cng - only on net461 as a result of the netstandard remapping. Fix here is to drop those types from the reference for the netfx build. - System.Threading.AccessControl 1 is a must-fix for 2.0. For 2 and 3 we'd need to ship the individual packages and for that I'd like a shiproom read. 23831 area-Infrastructure Switch OSX CI runs to use Helix 23832 area-System.Xml Make Xunit detect tests from Xml custom test fx (no more outerloop tests in S.P.Xml) This improves debuggability of XML tests.

If not, we should probably make sure it isn't marked as inbox there. We should also retarget master to something after UWP6 so we don't let things get out of sync (like we did with netcoreapp2.1 and I had to clean up later with https://github.com/dotnet/corefx/pull/23168). /cc @joperezr @weshaggard 23838 area-System.Collections ConcurrentDictionary: Reduced branching during GrowTable() Oh well, just some micro optimization for the GrowTable() method.

This would result in a slightly bigger newLength than MaxArrayLength (214643507**3** vs 214643507**1** to be precise) if that's acceptable.

From that point onwards the check if it should be grown even further during a `Grow()` operation comes down to just checking this one boolean variable as opposed to comparing the `tables._locks.Length < MaxLockNumber` on top of the boolean.

A bit of recent history: > This issue arose as part of a more general push to move useful APIs off of `TypeInfo` to more accessible locations. While considering what to do with the `TypeInfo.GetDeclaredXXX` family of APIs we though, if we do move them let's change their signatures so they're each able to specify each type of info they retrieve. The idea of moving the `GetDeclaredXXX` met with a lukewarm response and is not specifically what this issue is addressing. Here we address the proposal to ensure we have methods to return a single info. https://github.com/dotnet/corefx/issues/23762#issuecomment-327633532 @AtsushiKan --------------------- Right, I think we're on the same page. We want an api that lets you pass everything that guarantees a single (or zero) result. The existing api `Type.GetMethod(string name, int genericParameterCount, BindingFlags bindingAttr, Binder binder, CallingConventions callConvention, Type[] types, ParameterModifier[] modifiers)` comes pretty close. I know of at least two things it's missing: 1. Return type (e.g. the `operator explicit` case, though it's not limited to that of course.) 2. Custom modifiers on parameter types. You can overload on them too. The thing is, that for this to have any chance of getting approved, it really has to get it right. We've got so many overlapping apis to do the 99% job already - if it doesn't really solve something 100%, it's not going to be added. https://github.com/dotnet/corefx/issues/23762#issuecomment-327830616 @AtsushiKan --------------------- The uber-GetMethod is a much more ambitious effort (and much harder to justify on a cost-benefit basis - Reflection has been demented with regard to custom modifiers since its inception and it doesn't seem to have mattered much in the real world.) That can wait for another day. --------------------- So this may just be a place holder to collect any ideas about this for some future release. 23854 area-System.Reflection Move and make `TypeInfo.GetDeclaredXXX` APIs symmetric with `RuntimeReflectionExtensions.GetRuntimeXXX` _Carving this discussion out of #23762_ # Proposal Hold on.

We changed the AsSpan() method into an abstract property named Span. - When do we intend to use properties versus methods for span/memory related conversions? 2. Should we add the ""bulk"" operations that are available on Span\ to Memory\ as well such as the ones listed below: - Where would the extension methods for Memory go? Its own MemoryExtensions class like SpanExtensions or should we merge them both into one? Given these are extension methods (and the classes won't appear in user code), I would say they should go in separate MemoryExtensions class. ```C# // instance methods public struct Memory { public void CopyTo(Memory destination); public bool TryCopyTo(Memory destination); public void Fill(T value); public void Clear(); } public struct ReadOnlyMemory { public void CopyTo(Memory destination); public bool TryCopyTo(Memory destination); } // extension methods public static class MemoryExtensions { public static int IndexOf(this Memory memory, T value); public static int IndexOf(this Memory memory, ReadOnlyMemory value); public static int IndexOf(this ReadOnlyMemory memory, T value); public static int IndexOf(this ReadOnlyMemory memory, ReadOnlyMemory value); public static bool SequenceEqual(this Memory first, ReadOnlyMemory second); public static bool SequenceEqual(this ReadOnlyMemory first, ReadOnlyMemory second); public static void CopyTo(this T[] array, Memory destination); public static Memory AsMemory(this T[] array); public static Memory AsMemory(this ArraySegment arraySegment); public static ReadOnlyMemory AsReadOnlyMemory(this T[] array); public static ReadOnlyMemory AsReadOnlyMemory(this ArraySegment arraySegment); } ```

Using XmlReader for just reading XML without validation still pulls in all of the XmlSchema code. This makes the AOT compilation slow (it's more than 400KB of IL) and the resulting app is larger (.NET Native X86 measures the difference at more than 800KB of native code). The change relies on an assumption, that apps which don't need validation will not call the XmlReaderSettings.ValidationType setter. As such it can be reduced away and the change then ties all the dependencies needed for validation to that setter. So if the setter itself is not called XmlSchema is not pulled in. Verified that the change does reduce the app size and that XmlSchema is not in final app anymore. 23868 area-System.Net Remove duplicate bug ids in source code. fixes #23140 These tests will anyways be skipped by failing the conditional theory on each individual test in the base test class. 23869 area-Serialization Fix 4 Serialization Tests Fix 4 serialization tests.

This type provides strong guarantees in concurrent code and eliminates many concerns related to ownership when both `IDisposable` and `IRetainable` are at play. It also provides a weak reference type with strong semantic guarantees. cc @KrzysztofCwalina, @shiftylogic _Copied from original issue: dotnet/coreclr#13840_ 23872 area-System.Runtime Expose/test String.Create span-based method Depends on https://github.com/dotnet/coreclr/pull/13849 and https://github.com/dotnet/corert/pull/4467 Fixes https://github.com/dotnet/corefx/issues/22380 23873 area-System.Linq Faster Any() Linq query _From @banjouuid on September 7, 2017 15:38_ # Could Any() query be faster?

As a result of this the option is to make buffer pooling a conscious opt-in choice by the user; so it is safe by default and can be more performant on the opt-in. ## Proposal https://github.com/dotnet/corefx/issues/23874#issuecomment-333624280 ```csharp public partial class StreamWriter { static int DefaultBufferSize { get; } static int DefaultFileBufferSize { get; } static Encoding DefaultEncoding { get; } StreamWriter(Stream stream, Encoding encoding = DefaultEncoding, int bufferSize = DefaultBufferSize, bool leaveOpen = false, ArrayPool charPool = null, ArrayPool bytePool = null); } ``` ### Previous proposal ```csharp public partial class StreamWriter { StreamWriter(Stream stream, bool useBufferPooling) StreamWriter(Stream stream, bool useBufferPooling, Encoding encoding) StreamWriter(Stream stream, bool useBufferPooling, Encoding encoding, int bufferSize) StreamWriter(Stream stream, bool useBufferPooling, Encoding encoding, int bufferSize, bool leaveOpen) } ``` ## Comment Similar pattern could be extended to other areas with longer lived buffers, like `FileStream` etc /cc @stephentoub @JeremyKuhne @jkotas @KrzysztofCwalina 23875 area-System.Reflection Does CoreFX library support NI file, including both FNV and R2R ?

If PEReader accepts a stream from a pe file and the pe file is FNV or R2R NI file, all corefx apis are handling the case? p.s. the reason why I ask about that, `System.Reflection.Metadata.Decoding.Tests.CustomAttributeDecoderTests.TestCustomAttributeDecoder` in `System.Reflection.Metadata.Tests'` always is failed on NI overlay + NI TC-FNV&R2R.

public static Memory AsMemory(ReadOnlyMemory readOnlyMemory); } } ``` # Original Proposal We already have `DangerousTryGetArray(...)` on `ReadOnlyMemory`, as well as `rom.Span.DangerousGetPinnableReference()`, so it's possible to get writable access to the underlying data. But there's currently no efficient way to get a `Memory` from a `ReadOnlyMemory`. This is relevant for cases where a shared data structure or API needs to be usable from APIs that work with either `Memory` or `ReadOnlyMemory`. For example, Socket.SendAsync will take a `ReadOnlyMemory`, but the underlying SocketAsyncEventArgs type only works with `Memory`, because it needs to support both read and write APIs. If there's no way to efficiently convert a `ReadOnlyMemory` to a `Memory`, we'll need to increase the size of such objects to store both, and potentially add branching in a variety of places to make sure the right underlying field is being used. I propose we add the following method to `ReadOnlyMemory`: ```C# public Memory DangerousAsMemory(); ``` cc: @KrzysztofCwalina, @ahsonkhan 23881 area-System.Memory ReadOnlySpan.DangerousGetPinnableReference should return a readonly reference Should ```csharp namespace System { public struct ReadOnlySpan { public ref T DangerousGetPinnableReference() ``` be ```csharp public ref readonly T DangerousGetPinnableReference() ↑ ``` ?

This idiom will not work with the recently added Signature Types (https://github.com/dotnet/corefx/issues/16567) as these types do not have a `MethodInfo` to return and will always throw on a `DeclaringMethod` call. While one could work around this today by writing this: ```c# IsGenericMethodParameter => IsGenericParameter && (IsSignatureType || DeclaringMethod != null) ``` this is not very intuitive, nor is it future-proof as it's not inconceivable that in the future, we may add the ability to create signature types representing unbounded generic type parameters. Even for regular types, these new properties are more succinct, expressive and allow properly factored underlying implementations (CoreRT) to override with the maximally performant ""return true/false"" implementations, eliminating a virtual call. Signature Types, of course, will have to override. # Naming Naming is consistent with the recently added ```c# Type MakeGenericMethodParameter(int position) ``` api." 23884 area-System.Memory Support casting ReadOnlySpan to Span # Proposal ``` struct ReadOnlySpan { public Span DangerousAsSpan(); } ``` I have not found a workable way to do this (at least one that works across both fast and slow Span.) This functionality is needed to bridge code that uses ReadOnlySpan with code that supports both reading and writing (Span). 23886 area-System.Net WebRequest.DefaultWebProxy: Set doesn't work without a previous Get Unless we do an unnecessary Get() on WebRequest.DefaultWebProxy, any Set() done will not be honored. This is especially a problem on Linux, where DefaultWebProxy throws PlatformNotSupportedException(). This in turn breaks libraries like WindowsAzure.Storage which fail unless the Get() is called first and then WebRequest.DefaultWebProxy is set to null. This fix avoids the unnecessary Get() by setting the already initialized flag sent to the LazyInitializer. // bug created to track 2.0 port https://github.com/dotnet/corefx/pull/22720 23887 area-System.Diagnostics Process.ProcessName is expensive on Windows It causes an enumeration of all processes just to get the name of the current process https://source.dot.net/#System.Diagnostics.Process/System/Diagnostics/Process.cs,900 https://source.dot.net/#System.Diagnostics.Process/System/Diagnostics/ProcessManager.Windows.cs,53 On Windows it could call just GetProcessName.

"@davidsh words: ""This test is failing now because it is running against the ""Full Framework"". But for System.Net.Http tests, even running against ""Full Framework"" means that it should use the OOB System.Net.Http and not the inbox System.Net.Http from the .NET Framework. Something has changed in how the test binaries are laid out and consumed. The tests appear to be using the inbox System.Net.Http binary and not the OOB System.Net.Http binary (net46 build from package).

Thanks, Mandar 23916 area-System.Runtime S.R.CS.Unsafe and read-only references Most (if not all) APIs today are defined to accept references with `ref` rather than `ref readonly`. This includes all methods of the `Unsafe` class. This proposal is to provide a method to turn a `ref readonly T` into a `ref T`, so that read-only references can be passed to methods that use `ref` but are known to be only reading them. ```diff public static partial class Unsafe { ... + public static ref T AsRef(ref readonly T source) } ```
Original proposals (click to expand) A few proposals for APIs related to the System.Runtime.CompilerServices.Unsafe class and read-only references. **Proposal 1:** Change `ref T` to `ref readonly T` where possible: ```diff public static class Unsafe { public static ref T AddByteOffset(ref T source, System.IntPtr byteOffset) public static ref T Add(ref T source, int elementOffset) public static void* Add(void* source, int elementOffset) public static ref T Add(ref T source, System.IntPtr elementOffset) -

23917 area-System.Runtime S.R.CS.Unsafe: Aligned vs Unaligned method name suffix "The new Intel Intrinsic APIs (https://github.com/dotnet/corefx/pull/23489) follow the convention of using the suffix `Aligned` for methods that require alignment. E.g.: ```csharp public static unsafe Vector256 Load(byte* address) public static unsafe Vector256 LoadAligned(byte* address) ``` The System.Runtime.CompilerServices.Unsafe class currently does the opposite. E.g.: ```csharp public unsafe static T Read(void* source) public unsafe static T ReadUnaligned(void* source) ``` Should the Unsafe class switch? Benefit: ease of use.

As you can see, I used `Stopwatch` to measure the duration of the call and it is generally about 45 seconds, give or take. I usually have the time to open a new browser instance and navigate to the URL by myself while the request is called. I also tried with `HttpClient`: ```c# private static void WithHttpClient() { Stopwatch sw = new Stopwatch(); sw.Start(); using (var client = new HttpClient()) { client.BaseAddress = new Uri(""http://www.dot.net""); var content = client.GetStringAsync(string.Empty).Result; sw.Stop(); Console.WriteLine(content); Console.WriteLine($""Response got in {sw.ElapsedMilliseconds / 1000}""); } } ``` And I obtain approximately the same result.

Replace with assertions. * Remove `bytes == null` branch from `UrlDecodeToBytes` Exists in a `bytes != null` branch, so never `true`. * Remove `sb.Length` test from `HttpQSCollection.ToString()` In a path for which there will always be at least one value added, so always true, so just use offset & length overload of `ToString`. * Remove check that `authorityIndex != -1`. Cannot be `false` in the branch it is in. * Change `JavaScriptStringEncode` call to avoid unnecessary branch. Can just call `HttpEncoder.JavaScriptStringEncode` directly. * Move switch for determining js escape into first `CharRequiresJavaScriptEncoding` branch. Removes need for double-check. * Add test for `JavaScriptStringEncode` with `false` for `addDoubleQuotes` * Always have braces in `if` * Remove redundant casts. * Use explicit types. * Use expression-body syntax * Use PascalCase for constant. 23922 area-System.Runtime Roundtripping DateTime with mn-MN FullDateTimePattern on Windows 8.1 fails ``` Unhandled Exception of Type System.FormatException Message : System.FormatException : The string was not recognized as a valid DateTime.

This can be seen when running: `penssl s_client -connect 192.168.1.11:8080` The results on Windows include ``` No client certificate CA names sent ``` On Linux, however, the server will send a list of all the trusted issuers on the system. This is actually handled by CoreFX directly, in this method: https://github.com/dotnet/corefx/blob/0fd3d2c5bcb1a83e7ebd8025e4810e11e231ce03/src/Common/src/Interop/Unix/System.Security.Cryptography.Native/Interop.OpenSsl.cs#L323 The code there is explicitly adding the registered certificates. On some machines, this can be a VERY big list. However, the calling code has no control over that and has to accept the machine state. This is problematic, and a solution that will allow us to control what are the trusted issuers would be much better for us. The underlying reason is that currently a user may specify a certificate, but get an error that no such certificate was used, which is really confusing and require to dig into which is the trusted issuer, what is going on and a lot of other annoyances. There is also now way for us to inject any behavior into the system to control it. Another overload on `SslStream` that would allow configuring the ssl context directly before use would be much better, but anything that would allow us to avoid sending the full issuers list all the time would be sufficent. This seems to impact quite a few people and it is the cause of very hard to diagnose issues. 23940 area-System.Runtime Cleanup code in System.Runtime.Serialization.Formatters.Tests @krwq if you have time it would be nice if you can review my changes as you contributed a fair amount of code to it :) Motivation for changes: 1.

But in .NET Core, this flag is ignored. There doesn't seem to be a good reason for this flag not to work: the underlying mechanism it relies on (the correlation manager in `Trace`) appears to be present and works as required, so it's not as this this requires some base functionality that is missing in .NET Core. This seems similar to the issue fixed by https://github.com/dotnet/corefx/pull/18185 and with a very similar underlying reason. https://github.com/dotnet/corefx/issues/10880#issuecomment-291763962 in the issue for that PR notes refers to https://github.com/dotnet/corefx/issues/17773#issuecomment-290952601 that points out the difference between Desktop .NET and .NET Core that led to the descrepancy in #10880. You can see a similar difference for `TraceListener` between Desktop .NET: https://referencesource.microsoft.com/#System/compmod/system/diagnostics/TraceListener.cs,417 and the corresponding `WriteFooter` implementation in .NET Core: https://source.dot.net/#System.Diagnostics.TraceSource/System/Diagnostics/TraceListener.cs,414 As you can see .NET Core just doesn't have the code that handles this flag. It looks like the underlying `Trace.CorrelationManager.LogicalOperationStack` works as expected under .NET Core so there doesn't seem to be any obvious reason for this feature to be missing from `TraceListener` (any more than there was any reason for the corresponding feature to be missing from `DelimitedListTraceListener` before that was fixed by https://github.com/dotnet/corefx/pull/18185 23945 area-Infrastructure Use linker from ILLink.Tasks This tasks package contains the newest version of the linker, which comes with an msbuild task.

It then does `.Contains()` on them with a value. ## What is happening The code on the referenced line (2305) does the following: 1. Retrieve the value of a property (`get`) 1. Verify if the property if writable 1. If so, write the retrieved value to the property https://github.com/dotnet/corefx/blob/master/src/System.Linq.Expressions/src/System/Linq/Expressions/Interpreter/LightCompiler.cs#L2305 ## What I expected I didn't expect the expression to call the setter of my property.

This `XmlDocument` does NOT work with the invalid xml data which contains about 6,000 xml-nametag. This invalid xml data is provided by 3rd party company that is last updated 12 years ago and it won't modify this invalid xml because of their integration mess. Looking at `SignXml.cs` source code in this GitHub, I discovered that it is only a xml builder that use varieties of Crypography stuff that get assigned as xml's value. This show that is is possible to use Cryptography without XmlDocument somehow. We have no control over telling `XmlDocument` to ignore invalid xml data for this to work. 24015 area-Serialization Remove ContinueAsError in sgen test @shmao 24018 area-Infrastructure System.Runtime.Serialization.Primitives version 4.2.0.0 "I recently started migrating some library projects to .NET Standard 2.0.

The immediate value of this change is that we can turn on SourceLink support which allows Visual Studio to 'just work' and step into source it fetches from this Github repository. This is an important step in getting this working for our shipped builds. It is possible to get SourceLink working without generating Portable PDBs but I believe we want to move in this direction sooner rather than later because. 1. ASP.NET ships this way (and we expect most code will ship using Portable PDBs) 2. This is the way we ship on Linux 3. VSCode only supports portable PDBs (at least in my experimentation). 4. Because of (1) we already have support for generating MS-PDBs from the portable ones and uploading them to Microsoft Symbol Servers (which currently only support In short, uniformity is good, and this makes us significantly more uniform. The only issue is what 'breaks'. Because of (4), it is not clear that any important scenario is actually broken by the change. To the degree that we publish PDBs via the MS symbol server, those were converted before publication so things will work as the do now. For private builds, VS works with portable PDBs. Tests should be using portable (so they can run on Linux too). Now I am sure that we might break something, but we are likely to be close enough that it is easier/better to simply try it and clean it up (or revert it), if we run into issues. But I have marked this NO-MERGE for the time being so that we can vet any concerns. If after several days of vetting we have addressed all concerns we would be in a position to proceed.

For the most part, it's a breeze. When it comes to deserializing enum attribute arguments, the System.Reflection.Metadata API requires me to provide the underlying type and then of course I want to be able to output that as the appropriate field name rather than as an integer cast to the enum's name. This requires me to look up an assembly on disk given (1) the path to the assembly I'm currently examining and (2) an AssemblyName instance which I create from the AssemblyReferenceHandle. It's easy enough to use `Assembly.ReflectionOnlyLoad` and non-Metadata reflection API to locate the enum field, but I see even `ReflectionOnlyLoad` as undesirable: - It keeps the assembly in memory - It slows the process down by reading and processing more than it absolutely needs to - It loads in the context of the generating process, not the assembly being examined which might be anywhere on disk, so it might resolve to the wrong file - In the process of examining multiple assemblies, it might try to load different versions of an assembly with the same name and no strong name - It forces me to switch from doing everything with the MetadataReader to reimplementing the same logic with ‘normal’ reflection for enums defined outside the assembly being examined Would you please expose an API which locates the assembly that would be loaded if the running process were the assembly being examined, given the `AssemblyName`, and passes back a file path which I can then open with the MetadataReader? Is there a better way to achieve what I want without this API, and without the list of issues that I see with `Load` and `ReflectionOnlyLoad`?

CC @stephentoub @Priya91 @MattGal 24039 area-System.IO Proposal: Add protected {Unmanaged}MemoryStream.Read/WriteSpan method We've added new virtual `Read(Span)` and `Write(ReadOnlySpan)` methods to Stream, and overridden them on MemoryStream and UnmanagedMemory stream. However, these new overrides can't just directly write to the in-memory storage: existing types derived from these that override the existing Read/Write virtuals would have their logic skipped until they also overrode the new property. To address that, these overrides check the concrete type of the stream (e.g. `if (GetType() == typeof(MemoryStream)`), writing directly to the storage of it's not a derived type, and delegating to the existing virtuals if it is a derived type. This, however, causes a potential perf issue for a derived type. It's often the case with such derived types that they do a bit of work and then delegate to the base implementation, but that base implementation will then proceed to see that it's a derived type and skip the efficient path. To re-enable that efficiency, we need a way for the derived type overriding the new virtuals to call the efficient implementation and skip the type check. I propose we add the following: ```C# class MemoryStream & class UnmanagedMemoryStream { protected void WriteSpan(ReadOnlySpan source); protected int ReadSpan(Span destination); } ``` to both MemoryStream and UnmanagedMemoryStream. cc: @JeremyKuhne, @ianhays, @KrzysztofCwalina, @ahsonkhan 24040 area-System.IO NamedPipeServerStream: Provide support for WRITE_DAC When creating a `NamedPipeServerStream` on Windows, `WRITE_DAC` on `CreateNamedPipe` will always be unset.

In case the installed libcurl was build against libssl.so.1.0.2, we end up having both versions of libssl loaded in the process. And only the one with version 1.0.0 gets the locks initialized and so we end up crashing due to the infamous multithreading issue. Since our SSL shim doesn't know which version of SSL the CURL uses, I think that it would make sense to add an env variable that would enable overriding the OpenSSL version .NET core uses.

I am currently trying to update my blog post/presentation about Span. I read the code and I have few questions. I hope that you can help me to get a better understanding. 1. One of the reasons for making `Span` and `ReadOnlySpan` a stack-only types was to avoid struct tearing. `Memory` is a struct and it consist of 3 fields. By design it's not stack-only. Is it not going to suffer from struct tearing? Why is it not a class? 2. `ReadOnlyMemory.DangerousTryGetArray` is breaking the encapsulation by exposing `ArraySegment` which allows to modify the content via indexer (it has a setter). It's hidden from the IDE via `EditorBrowsable` attribute and has a name that indicates the consequences. Is this method really needed? Why not to introduce new type like `ReadOnlyArraySegment` ? cc @KrzysztofCwalina @jkotas 24068 area-System.Net Zero Width Space Hei guys, for some reason you are using [Zero Width Spaces](https://www.compart.com/en/unicode/U+200B) in your source code.

When trying to build CoreCLR in Alpine docker container, I have bumped into a strange issue when msbuild would fail with internal error when forking another copy of itself. strace revealed that it was calling ""access"" syscall with ""Tools/dotnetcli/shared/Microsoft.NETCore.App/2.0.0-preview1-002111-00/System.Private.CoreLib.ni.dll"" file as a parameter. Looking at where that syscall came from, it turned out it was SystemNative_ForkAndExecProcess in System.Native.so, which was called from a call chain stemming from Microsoft.Build.BackEnd.NodeProviderOutOfProcBase.LaunchNode. This function was passing in a result of the System.Diagnostics.Process.MainModule and it was returning that dll instead of the actual main module. It turns out that the System.Diagnostics.Process.MainModule relies on the main module being the first module listed in the /proc/self/maps. But in the Alpine container, it was not the case. I can see two ways to fix that. Either ensure that the modules ProcessManager.GetModules always returns the main module as the first one or change the System.Diagnostics.Process.MainModule to search for the main exe by looping through all the modules and comparing their FileName to the Process.GetExePath(). And probably caching the result. I've verified that the second approach works. " 24072 area-System.Memory Span extension method to slice off of a string instance # [Current API proposal](https://github.com/dotnet/corefx/issues/24072#issuecomment-347610584) TODO (see https://github.com/dotnet/corefx/issues/24072#issuecomment-349412729): Add array overloads. Consider ArraySegment overloads for consistency. ```cs public static class MemoryExtensions { public static ReadOnlySpan AsReadOnlySpan(this string text, int start); public static ReadOnlySpan AsReadOnlySpan(this string text, int start, int length); public static ReadOnlyMemory AsReadOnlyMemory(this string text, int start); public static ReadOnlyMemory AsReadOnlyMemory(this string text, int start, int length); } ``` ---- # Original post I expected to see these: ```cs class System.SpanExtensions { public static ReadOnlySpan Slice(this string text, int start); public static ReadOnlySpan Slice(this string text, int start, int length); } ``` But now I also see a proposal for a non-stack-only [`StringSegment`](https://github.com/dotnet/corefx/issues/20378) type. So I have two questions. 1. Is there a clearly preferable return type for such an extension method? 2. Is the most efficient way to slice a string `str.AsReadOnlySpan().Slice(...)`, or is there a single method call I can make that I haven't found yet? That's a little verbose for my liking, even if the two calls are inlined. 24074 area-System.Net Error while copying content to a stream.

The way that we represent characters in .NET is with `System.Char` which is a 16-bit value, one that is insufficient to represent Unicode values. .NET developers need to learn about the arcane Surrogate Pairs: https://msdn.microsoft.com/en-us/library/xcwwfbb8(v=vs.110).aspx Developers rarely use this support, mostly because they are not familiar enough with Unicode, and let alone what .NET has to offer for them. I propose that we introduce a `System.Rune` that is backed by 32 bit integer and which corresponds to a codePoint and that we surface in C# the equivalent `rune` type to be an alias to this type. `rune` would become the preferred replacement for `char` and serve as the foundation for proper Unicode and string handling in .NET. As for why the name rune, the inspiration comes from Go: https://blog.golang.org/strings The section ""Code points, characters, and runes"" provides the explanation, a short version is: > ""Code point"" is a bit of a mouthful, so Go introduces a shorter term for the concept: rune. The term appears in the libraries and source code, and means exactly the same as ""code point"", with one interesting addition. *Update* I now have an implementation of `System.Rune` here: https://github.com/migueldeicaza/NStack/blob/master/NStack/unicode/Rune.cs With the following API: ``` public struct Rune { public Rune (uint rune); public Rune (char ch); public static ValueTuple DecodeLastRune (byte [] buffer, int end); public static ValueTuple DecodeLastRune (NStack.ustring str, int end); public static ValueTuple DecodeRune (byte [] buffer, int start, int n); public static ValueTuple DecodeRune (NStack.ustring str, int start, int n); public static int EncodeRune (Rune rune, byte [] dest, int offset); public static bool FullRune (byte [] p); public static bool FullRune (NStack.ustring str); public static int InvalidIndex (byte [] buffer); public static int InvalidIndex (NStack.ustring str); public static bool IsControl (Rune rune); public static bool IsDigit (Rune rune); public static bool IsGraphic (Rune rune); public static bool IsLetter (Rune rune); public static bool IsLower (Rune rune); public static bool IsMark (Rune rune); public static bool IsNumber (Rune rune); public static bool IsPrint (Rune rune); public static bool IsPunctuation (Rune rune); public static bool IsSpace (Rune rune); public static bool IsSymbol (Rune rune); public static bool IsTitle (Rune rune); public static bool IsUpper (Rune rune); public static int RuneCount (byte [] buffer, int offset, int count); public static int RuneCount (NStack.ustring str); public static int RuneLen (Rune rune); public static Rune SimpleFold (Rune rune); public static Rune To (Case toCase, Rune rune); public static Rune ToLower (Rune rune); public static Rune ToTitle (Rune rune); public static Rune ToUpper (Rune rune); public static bool Valid (byte [] buffer); public static bool Valid (NStack.ustring str); public static bool ValidRune (Rune rune); public override bool Equals (object obj); [System.Runtime.ConstrainedExecution.ReliabilityContractAttribute((System.Runtime.ConstrainedExecution.Consistency)3, (System.Runtime.ConstrainedExecution.Cer)2)] protected virtual void Finalize (); public override int GetHashCode (); public Type GetType (); protected object MemberwiseClone (); public override string ToString (); public static implicit operator uint (Rune rune); public static implicit operator Rune (char ch); public static implicit operator Rune (uint value); public bool IsValid { get; } public static Rune Error; public static Rune MaxRune; public const byte RuneSelf = 128; public static Rune ReplacementChar; public const int Utf8Max = 4; public enum Case { Upper, Lower, Title } } ``` *Update Known Issues* - [x] Some APIs above take a uint, need to take a Rune. - [ ] Need to implement IComparable family - [ ] RuneCount/RuneLen need better names, see docs (they should be perhaps Utf8BytesNeeded?) - [ ] Above, the ""ustring"" APIs reference my UTF8 API, this is really not part of the API, but we should consider whether there is a gateway to System.String in some of those, or to Utf8String." 24095 area-System.IO NamedPipeClientStream.ReadAsync poor cancellation in the face of concurrent reads In general, concurrent asynchronous reads on the same Stream isn't supported. However, due to the underlying implementations on Windows, FileStream actually does allow for this when opened in asynchronous mode, as does NamedPipeClientStream. On Unix, to enable cancelable ReadAsyncs, we queue a work item that does a polling loop, to give the code opportunity to see a cancellation request, but this breaks down when there are potentially multiple outstanding read requests on the same stream: they'll all successfully poll and proceed to issue the synchronous read, at which point some may block indefinitely until more data is available, negating the extra effort made to enable cancellation. The right solution, once it's available, is simply to take advantage of the new Socket.ReceiveAsync overload that takes a CancellationToken in https://github.com/dotnet/corefx/issues/22608 and just pass the token through. It's then up to the Socket's implementation to appropriately respect cancellation. If that solution isn't available soon enough, we should enforce serialized reads via a SemaphoreSlim. 24096 area-Serialization Add the target to copy the serializer to publish folder. @shmao @zhenlan @mconnew 24097 area-System.Drawing Remove an assertion from PrintDocumentTests.cs. There are tons of PaperKinds (like 100+), so it's not really reasonable to make an assertion about every single one of them. The two we have above this seem to be the most common and are probably okay to check explicitly. I added some logging to see what kind of printer was in use in https://github.com/dotnet/corefx/issues/23992, but it turned out to be `PaperKind.Custom`. I don't think we can make any reasonable guesses about what the size of that is supposed to be, so I'm just going to remove this block here. 24098 area-System.Net Disable NegotiateStreamTest fixture for distros without working Kerberos because setup-kdc.sh is broken on some distros and this is failing 350 tests.

The reason is that on that platform, linux/in.h cannot be included on its own, the sys/socket.h needs to be included before that to provide definitions of some structures. In fact, Linux doc states that the sys/socket.h should be included before the linux/in.h. So I am fixing that by adding that include to the detection code. I have verified that it works on RHEL 6, Ubuntu 14.04, Alpine Linux and FreeBSD. 24101 area-System.ComponentModel Data-annotations length fix Fixes #24064 See [this](https://github.com/dotnet/corefx/issues/24064#issuecomment-330002471) comment. 24103 area-System.Memory Add Overlaps/Within extension methods for ReadOnlySpan This proposal adds utility methods for checking spans for overlaps or if a span is within in another span. For previous discussions see https://github.com/dotnet/corefx/issues/17793, https://github.com/dotnet/corefxlab/issues/827 and https://github.com/dotnet/corefx/issues/18750. And a closed PR https://github.com/dotnet/corefx/pull/18731. ### Proposed API Add two sets of extension methods `Overlaps` and `Within` for `ReadOnlySpan` in `SpanExtensions`: ```csharp public static class SpanExtensions { public static bool Overlaps(this ReadOnlySpan first, ReadOnlySpan second); public static bool Overlaps(this ReadOnlySpan first, ReadOnlySpan second, out int elementOffset); public static bool Within(this ReadOnlySpan first, ReadOnlySpan second); public static bool Within(this ReadOnlySpan first, ReadOnlySpan second, out int elementOffset);} } ``` * If `second` span does not match the alignment of `first` span an `ArgumentException` is thrown. * `out int elementOffset` is the relative offset or index of the start of the `second` span to the start of the `first` span. * `elementOffset` is only valid if the check in question returns `true`. ### Rationale and Usage For `Overlaps` the scenario can involve algorithms that transform elements from `first` to `second` span, if the spans overlap the result might be wrong depending on the algorithm. To be able to detect this the `Overlaps` method can be called. For `Within` the scenario can involve buffer pool management, where spans are leased from a buffer and later needs to be returned to a given buffer. Calling `Within` allows checking for which buffer the given span is within and thus where it must be returned to. #### Expected Results - **A**: `first` entirely before `second`, no overlap ``` first: [--------) xRef xRef + xLength second: [------------) yRef yRef + yLength ``` - **B**: `first` starts before `second` and ends inside `second` ``` first: [------------) xRef xRef + xLength second: [------------) yRef yRef + yLength ``` - **C**: `first` is entirely within `second` ``` first: [-----------------------) xRef xRef + xLength second: [--------------------------) yRef yRef + yLength ``` - **D**: `first` starts inside target `second` and ends after `second` end ``` first: [------) xRef xRef + xLength second: [-------) yRef . yRef + yLength ``` - **E**: `first` entirely after `second`, no overlap ``` first: [------------) xRef xRef + xLength second: [--------) yRef yRef + yLength ``` - **F**: `first` starts before `second` and ends after `second`, i.e. `second` is contained in `first` ``` first: [-------------------------------) xRef xRef + xLength second: [--------------------------) yRef yRef + yLength ``` - **G**: `first` is same as `second` ``` first: [--------------------------) xRef xRef + xLength second: [--------------------------) yRef yRef + yLength ``` - **H**: `first` is empty within `second` ``` first: [) xRef second: [--------------------------) yRef yRef + yLength ``` - **I**: `first` is empty before `second` ``` first: [) xRef second: [--------------------------) yRef yRef + yLength ``` - **J**: `first` is empty after `second` ``` first: [) xRef second: [--------------------------) yRef yRef + yLength ``` In table below `Overlaps => first.Overlaps(second)` or `Within => first.Within(second)`. `x => first` and `y => second`. | |`Overlaps` |`Within` |Extra checks/comment | |--------|-----------|-----------|---------------| |**A**/**E** |`false` |`false` |No way to know which case from these methods alone.| |**B** |`true` |`false` |`elementOffset > 0`| |**C** |`true` |`true` | | |**D** |`true` |`false` |`elementOffset < 0`| |**F** |`true` |`false` |`elementOffset >= 0 && xLength >= (elementOffset + yLength)`| |**G** |`true` |`true` |`elementOffset == 0 && xLength == yLength`| |**H** |`true` |`true` |`xLength == 0`| |**I**/**J** |`false` |`false` |No way to know which case from these methods alone.| #### Examples ```csharp public static void RepeatEvenIndices(ReadOnlySpan src, Span dst) { if (src.Overlaps(dst, out var elementOffset) && elementOffset >= -1) { throw new ArgumentException(); } for (int i = 0; i < src.Length / 2; i++) { dst[i + 0] = src[i * 2]; dst[i + 1] = src[i * 2]; } } ``` ### Open Questions Could this API be expressed differently, perhaps with an all encompassing `Overlap` method returning an enum? Performance downsides? Naming of the methods should be reviewed. ### Updates UPDATE 1: Rename `Contains` to `Within` with reversed `first`/`second` relationship, due to naming confusion. Rename `elementIndex` to `elementOffset` latter considered better. `elementOffset` only valid if check returns `true`. Revise table and add empty cases. cc: @ektrah @mgravell @ahsonkhan @shiftylogic @jkotas 24104 area-System.Net HttpWebRequest hits 1s timeout when resolving http://localhost on Win10 (.NET Framework is fast) "Consider the following method (error/exception handling omitted for brevity: ```c# public virtual string MakeHttpRequest(Uri fullUri, string httpMethod, string requestBody) { string responseString = string.Empty; HttpWebRequest request = HttpWebRequest.Create(fullUri) as HttpWebRequest; request.Method = httpMethod; request.Timeout = 30000; request.Accept = ""application/json,image/png""; if (request.Method == ""POST"") { string payload = requestBody; byte[] data = Encoding.UTF8.GetBytes(payload); request.ContentType = ""application/json;charset=utf-8""; Stream requestStream = request.GetRequestStream(); requestStream.Write(data, 0, data.Length); requestStream.Close(); } HttpWebResponse webResponse = request.GetResponse() as HttpWebResponse; using (Stream responseStream = webResponse.GetResponseStream()) using (StreamReader responseStreamReader = new StreamReader(responseStream, Encoding.UTF8)) { responseString = responseStreamReader.ReadToEnd(); } return responseString; } ``` Executing this method against a server running on localhost yields wildly different execution times when run via the full .NET Framework vs. .NET Core.

24115 area-System.Runtime Proposal: Add Array.Sort(T[], int, int, Comparison) overload The PR https://github.com/dotnet/coreclr/pull/8504 changed Array.Sort to be based internally on the `Comparison` delegate rather than on the `IComparer` interface, as delegate dispatch is faster than interface dispatch and it enabled consolidating two implementations. That means if an `IComparer` is provided, its Compare method is wrapped in a `Comparison` delegate. However, there is no overload of Array.Sort that takes the array, offset, length, and comparison delegate (the only overload that takes a delegate is `Sort(T[], Comparison)`: https://github.com/dotnet/corefx/blob/155a46c0c59fddefc009c2a4affd0fd2b3bac2b3/src/System.Runtime/ref/System.Runtime.cs#L305-L309 so if you have a delegate and need to provide offset+length, you first need to allocate an object implementing `IComparer` to wrap it so you can call the right overload, and then the implementation will wrap that with an allocated `Comparison`; that's two allocations and multiple levels of indirection when none of that is necessary. Instead, we should just add this overload: ```C# public static void Sort(T[] array, int index, int length, Comparison comparer); ``` cc: @mikedn, @jkotas, @joperezr, @AlexGhiondea 24116 area-System.Linq Use Array.Sort instead of custom QuickSort implementation in LINQ's OrderBy Fixes https://github.com/dotnet/corefx/issues/24110 The first commit just moves the various QuickSort implementations to the derived sealed class, to avoid some virtual dispatch for some of the comparison operations. The second commit then addresses the core of the problem, by using Array.Sort (an IntroSort implementation) instead of the custom QuickSort implementation used today; stability is provided by comparison operator utilizing the provided indices. It'll be easiest to review the commits individually. cc: @JonHanna, @VSadov, @OmarTawfik, @maxzav 24117 area-System.Net IPAddress.GetHashCode allocates a string for IPv6 In order to return a hash code for IPv6 IPAddress calls (and caches) `ToString` and returns the result's hash code: ```csharp public override int GetHashCode() { if (IsIPv6) { if (_hashCode == 0) { _hashCode = StringComparer.OrdinalIgnoreCase.GetHashCode(ToString()); } return _hashCode; } else { // ... } } ``` These allocations constantly show up high on our list when we analyze our product's performance (even though the results are cached). Is there any reason not to just calculate the hash code from the internal `ushort[] _numbers` and `_addressOrScopeId`? A trivial implementation would be to simply xor all the values (but I can use something more complicated): ```csharp public override int GetHashCode() { if (IsIPv6) { if (_hashCode == 0) { int hashCode = (int)PrivateScopeId; for (int i = 0; i < NumberOfLabels; i += 2) { hashCode ^= _numbers[i] << 16 | _numbers[i + 1]; } _hashCode = hashCode; } return _hashCode; } else { // ... } } ``` I might be missing something obvious, but if not, I would love to remove these unnecessary allocations. 24120 area-System.Data Sql Connection Pooling "We are having issues when connecting from .net core application to sql server.

"Since switching to manual function loading, the OSX configuration of System.Drawing has been broken, because it tries to load functions from ""libgdiplus.so"", rather than ""libgdiplus.dylib"". The fix is fairly straightforward -- we just load a different file name when on OSX." 24124 area-System.Drawing [Question] What is the most efficient way to read/write `Vector` from/to managed memory? I'm optimizing floating-point color conversion methods for the [ImageSharp](https://github.com/SixLabors/ImageSharp) library, using the .NET Core 1.1 runtime for my experiments. I have to do several arithmetic operations using SIMD vectors and scatter the elements of the result vectors to different memory locations. I tried two approaches for this: 1. Read the input as `Vector` -> calculate -> [copy the vectors into an another struct on the stack, and use it for further operations](https://github.com/SixLabors/ImageSharp/blob/84944e2db9b74f4b5f226de33b3c8a5787dc8dc4/src/ImageSharp/Formats/Jpeg/Common/Decoder/JpegColorConverter.FromYCbCr.cs#L117). (Note: This is an AVX2 only execution path.) 2. [Do everything with `Vector4`.](https://github.com/SixLabors/ImageSharp/blob/343a8920d806d9d92efeb45c2f43f103fadfdbd4/src/ImageSharp/Formats/Jpeg/Common/Decoder/JpegColorConverter.FromYCbCr.cs#L95) With the first approach I was only able to reach a small (~`2x`) speedup compared to the scalar code, but the speedup was really significant with the second, `Vector4`-only solution. This is not what I expected. Correct me if I am wrong, but I started to think that the way I read/write `Vector` might prevent the JIT from generating optimized code. I ended up having the following question: Is there any difference in the quality of the generated machine code for this: ```C# ref FooStruct fooRef = ref GetFooRef(); // can be heap or stack reference Vector v = Unsafe.As>(ref fooRef); v+= new Vector(42); Unsafe.As>(ref fooRef) = v; ``` VS this: ```C# ref FooStruct fooRef = ref GetFooRef(); // can be heap or stack reference ref Vector vRef = Unsafe.As>(ref fooRef); vRef+= new Vector(42); ``` VS this: ```C# FooStruct* fooPtr = GetFooPtr(); // can be heap or stack pointer Vector v = Unsafe.Read>(fooPtr); v+= new Vector(42); Unsafe.Write>(fooPtr, v); ``` VS this? ```C# FooStruct* fooPtr = GetFooPtr(); // can be heap or stack pointer Vector v = Unsafe.ReadUnaligned>(fooPtr); v+= new Vector(42); Unsafe.WriteUnaligned>(fooPtr, v); ``` I'm interested in both: - Reading/writing `Vector` from/to unalinged managed heap locations - Reading/writing to a `struct` located on the stack Any hints? Is there something wrong with my approach? Should I ask this on `coreclr` instead?

I am making use of the Azure service bus client lib on OSX. When I receive messages from a topic subscription that are a part of a session (~300 sessions with 1-5 messages per session), and do so in parallel, I consistently (but in random locations) get an unmanaged ""pointer being freed was not allocated"" error (typically only 10-20ish sessions get processed). Using the same code, I do not get a crash on Windows 10. Based on the backtrace, this appears to be happening within the bowels of System.Net.Security.SSLStreamInternal, which granted, is documented to not be threadsafe (and is being re-entered). But in any case, I am doing as suggested and filing here.

handle and be able to call Accept() on it. This is useful to enable functionality like [systemd socket activation](http://0pointer.de/blog/projects/socket-activation.html). Ex. ```cs var listeningSocket = Socket.FromFileHandle(handle); //socket is already bound by the service manager var connectionScoket = listeningSocket.Accept(); //Send data through connectionSocket ``` 24145 area-System.Text Consider Span overloads on Regex classes **edit by @ViktorHofer, moved initial post down.** Spanifying Regex removes (a) unnecessary string allocations that tend to decrease perf and (b) allows different types of Memory to be processed. **API proposal and implementation:** https://github.com/ViktorHofer/corefx/pull/1 ## Proposed APIs This diff contains the Memory overloads and the MatchEvaluator overloads.

I had a discussion with Jan offline and he pointed out that we might want to introduce a `ref struct MatchValue` type that is returned by APIs that take Span/Memory as an input. > The problem with just using the current `class Match` is that it gives you unsecure access to the Span. For example, you can send the Match object to other thread and start working on the Span there, while the current thread unwinds and frees the memory. ref struct MatchValue would avoid this issue (And also saved the alllocation) The issues with that is that we currently have the following hiearchy: Match --> Group --> Capture and that Groups and Match contain collections of Captures/Groups. > Yes, the flip from class to valuetype tends to be like this. E.g. when we have introduced ValueTask to CoreFX, a bunch of parallel ValueSomething types went with it. It is a topic for API review discussion One option is to just not have Span version of the APIs that returns these collections or have callbacks ### startat overload > For things like Regex.Replace, the startat argument means copy everything up to startat to the destination Span, and then run regular Replace that does not take startat method. So this looks like a convenience method to me - it saves you from typing a tiny bit of code in rare cases to achieve the same effect. Should we add these startat convenience overloads for Span also? If yes, this commit should be reverted https://github.com/ViktorHofer/corefx/pull/1/commits/bf7d7f986faaa212476ceeac09ab71c8ab6c7fd5 ### RegexSplitEnumerator RTL yield order If you call the Span version of Regex.Split and pass `RegexOptions.RightToLeft` to it the yield order of the enumerator will also be right to left as we start looking for matches from right to left. The current implementation (which is not an enumerator!) reverses the captured strings before returning. ### RegexSplitEnumerator GetEnumerator (see ref diff) > I'm not aware of any other cases in the BCL where we have a GetEnumerator method like this on a struct enumerator. I understand you want it to be able to directly foreach the results without introducing an enumerable struct to serve as the return type, but I'm not sure this is a pattern we want to introduce. You should be sure to highlight this as part of any API review discussion. 24147 area-System.Net Remove invalid NameResolution tests The Dns_GetHostEntryAsync_* tests are fundamentally invalid because it's possible for the broadcast address, 255.255.255.255, to have a DNS mapping via manually modifying the hosts file.

This is very common in converters or some other types that take in any object and has to deal with it differently if it's a collection. Most common collections in .NET (`List`, `Dictionary`, `Collection`, also implement `ICollection`, so it falls through the '[countable](https://github.com/dotnet/corefx/issues/23578)' criteria. However, the [`HashSet`](https://github.com/dotnet/corefx/blob/master/src/System.Collections/src/System/Collections/Generic/HashSet.cs) class doesn't. So as explained in #23578, in order to obtain the `Count` of a `HashSet`, we'll have to use reflection if we don't know `T` at compile time (for example we have an `object` typed variable that we know it contains a `HashSet`, but `T` can be anything, and is irrelevant to be able to get the count. ### Suggestion I'd prefer seeing this issue addressed as it should be in the first place, which is having a non-generic middle interface that signifies the `Count` property, but meanwhile, having the `HashSet` implement `ICollection` will bring the `HashSet` to this countable group as well, even as a temporary solution. ### Things to consider - If we do implement `ICountable`, we have another class to take care of before getting rid of the `ICollection` part, if we want to. - Please comment on [EDIT] Fixed code link by @karelz 24157 area-System.ComponentModel Dataannotations length fix - Formatting exception Fixes #24064. 24158 area-System.Text Port Regex.Compiled in-memory compilation of regex patterns from Desktop ## Changes - Reenabled compilation of regex patterns when compiled flag is set - Cleanup ref sources as they aren't compiled against netstandard anymore - Reenable more tests for uap/uapaot ## Issues The `CompileToAssembly` API (RegexTypeCompiler.cs) depends on `System.Reflection.Emit.AssemblyBuilder.Save` (https://github.com/dotnet/corefx/issues/4491) which isn't in Core yet. => No pre-compilation of regex patterns into assembly possible ## Potential future optimization The current Regex implementation produces a lot of HEAP pressure.

That requires a process-wide setting which makes it impossible to create an individual HttpClient{Handler} that uses ManagedHandler; another thread could be instantiating one at the same time and would pick up the setting. This is why we had to disable parallel execution of our System.Net.Http test suite. We still haven't yet figured out the final model via which we'll enable usage of ManagedHandler. For now, though, I'm adding a thread-local switch, to allow opting in a single HttpClientHandler construction.

The issue is there's no option to encode the SerialNumber as decimal value instead of hexadecimal value. The 3rd party company require it be in decimal value, not hexadecimal value. ```c# var keyInfo = new KeyInfo(); keyInfoData.AddIssuerSerial( x509Certificate2.Issuer, new BigInteger( x509Certificate2.GetSerialNumber() ).ToString(); // This is decimal value ); keyInfo.AddClause(keyInfoData); signedXml.KeyInfo = keyInfo; ``` As a workaround, I had to do this to make it work. ```c# var keyInfo = new KeyInfo(); var xmlDoc2 = new XmlDocument(); var x509IssuerName = xmlDoc2.CreateElement(""X509IssuerName""); x509IssuerName.InnerText = x509Certificate2.Issuer; var x509SerialNumber = xmlDoc2.CreateElement(""X509SerialNumber""); x509SerialNumber.InnerText = new BigInteger(x509Certificate2.GetSerialNumber()).ToString(); var x509IssuerSerial = xmlDoc2.CreateElement(""X509IssuerSerial""); x509IssuerSerial.AppendChild(x509IssuerName); x509IssuerSerial.AppendChild(x509SerialNumber); var x509Data = xmlDoc2.CreateElement(""X509Data""); x509Data.AppendChild(x509IssuerSerial); var keyInfoNode = new KeyInfoNode(); keyInfoNode.Value = x509Data; keyInfo.AddClause(keyInfoNode); signedXml.KeyInfo = keyInfo; ``` This source code in `KeyInfoX509Data.cs` class, line # 165 showed that `NumberStyles.AllowHexSpecifier` is hardcoded that give us non-decimal value as `out h` output value.

The ManagedHandler does support this, but is missing other functionality needed. WCF needs a way to instantiate a single HttpClientHandler instance to explicitly use ManagedHandler. If an instance of a WCF ChannelFactory has been configured to use certificate authentication, we need to be able to use a custom certificate validation callback so need to use ManagedHandler for that instance. If in the same process a different authentication mechanism is requested for a different instance of a WCF ChannelFactory, that instance needs to use the libcurl based HttpClientHandler implementation as it is more feature complete. While we can set the relevant environment variable before calling the HttpClientHandler constructor and then restore it to it's previous state, this isn't thread safe as we could interfere with an instantiation happening outside of WCF on another thread. 24191 area-Serialization Should not Pack Generated Serialization Assembly The serialization assembly generated by SGen should not be packed into the library's nupkg. 24192 area-System.Text System.Text.Encoding.Unicode Performance Slower than .NETFramework2.0 Not sure if this is the correct place but after profiling a library I'm working on I found that System.Text.Encoding.Unicode.GetString was 10x slower in .NETCore/>=.NETFramework4.0. However I found that this was not the case in <=.NETFramework3.5 on my machine. Maybe the performance degregadation could be attributed to something else but it was equivalent benchmarking code ran on .NET Core and >=.NETFramework4.0 and .NETFramework2.0-3.5. The .NETFramework 2.0 was faster for only the System.Text.Encoding.Unicode.GetString which seemed very peculiar.

Currently, when I have a number of `Task` instances where I want to perform aggregate operations across all of them (waiting for all of them to complete, for any of them to complete, etc.), I like to use the static `WhenAll`, `WhenAny`, etc. methods. I also like to use `ValueTask` as well for areas where I don't need the heap allocation that a `Task` brings. That said, I can't currently use `WhenAll`, `WhenAny`, etc. because they take sequences of `Task`. While there *are* workarounds, all of them fall short in some way: * I could call `AsTask`, but then that allocates a `Task` and call the existing methods on `Tasks` but the allocations is the situation I was trying to avoid in the first place. * I could write my own, but [the coreclr implementation is quite robust](https://github.com/dotnet/coreclr/blob/eb2e9f90ba3679fa8386c4130f81c8061e8d4ca4/src/mscorlib/src/System/Threading/Tasks/Task.cs#L5501), and I'd certainly miss situations that are coded for in there. This specific example is for `ValueTask` but it really applies to any awaitable type. I also think we'd need a new signature for `WhenAny`; the current implementation returns a `Task`, and the pattern to figure out *which* task finished is to do an equality comparison on the reference returned. I don't really agree that [checking the result as `ValueTask` does](https://github.com/dotnet/corefx/blob/master/src/System.Threading.Tasks.Extensions/src/System/Threading/Tasks/ValueTask.cs#L90) is the right way (imagine waiting on signals for `true`/`false` results from multiple votes, checking equality on the result won't work here). 24198 area-System.Diagnostics Make GetProcessInfo() for a single PID cheaper on Windows "Fixes #23887 Here we go then. Nothing spectactular, really, but should get the job done. I was wondering how to go about the PID filter parameter and I ended up using the dreaded ""default value: magic number"" approach to disable the PID filter and return all information about all processes like so: `private const int AllProcessIds = -1;` `internal static ProcessInfo[] GetProcessInfos(int processId = AllProcessIds)` Other alternatives I considered were a `Predicate` based one and a `params int[]` based one - none of which seemed particularly more readable or fast. Also, coming up with an entirely new piece of code for the single position retrieval didn't seem like a great idea since the `Interop.NtDll.NtQuerySystemInformation` seems to return one big blob of information about all processes anyway so I would have had to duplicate lots of code." 24199 area-Serialization Remove the line that will copy the generated serializer to the pack. #24191 @shmao @zhenlan 24200 area-Infrastructure Reference assemblies should not be loaded for execution I am getting this build error after upgrading to .net core 2 'Could not load file or assembly 'System.Data.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken= ***' or one of its dependencies.

Although `libgdiplus.dylib` can be acquired via Homebrew, we try to make it a ""plug & play"" experience and ship `libgdiplus.dylib` as part of our self-contained app. `libgdiplus.dylib` therefore is not preinstalled on our CI servers; we acquire it via the `runtime.osx.10.10-x64.CoreCompat.System.Drawing/1.0.1-beta004` package. The same holds true for our end user's desktops - it is currently not a requirement that they run `brew install libgdiplus` before launching our self-contained app. It appears that the `dlopen` call which is used to load `libgdiplus.dylib` does not use same search path as an `[DllImport]` statement - apparently the NuGet packages are not being searched.

After some experimentation, it seems to me that unlike `NamedPipeClientStream`, `AnonymousPipeClientStream` (or `AnonymousPipeServerStream` for that matter) does not support cancellation (because there's no way to open the pipe in async mode and so `Stream.ReadAsync` is used instead of `PipeStream.ReadAsyncCore`). This is a little painful because it means there's no way to ""unblock"" a pending read or write on that stream when the stream contains no data. Here's a simple repro that shows what I'm trying to do. It works for named pipes, but not for anonymous ones: ```csharp NamedPipeServerStream source = new NamedPipeServerStream(""pipe-test"", PipeDirection.Out, 1, PipeTransmissionMode.Byte, PipeOptions.Asynchronous); NamedPipeClientStream destination = new NamedPipeClientStream(""."", ""pipe-test"", PipeDirection.In, PipeOptions.Asynchronous); await destination.ConnectAsync(); CancellationTokenSource cancellationSource = new CancellationTokenSource(); byte[] buffer = new byte[10]; Task readTask = destination.ReadAsync(buffer, 0, buffer.Length, cancellationSource.Token); // Right now, readTask is blocked waiting for data. Task timeout = Task.Delay(TimeSpan.FromSeconds(1)); Task winner = await Task.WhenAny(readTask, timeout); Assert.Equal(timeout, winner); cancellationSource.Cancel(); // readTask will now fault with TaskCanceledException timeout = Task.Delay(TimeSpan.FromSeconds(5)); winner = await Task.WhenAny(readTask, timeout); Assert.Equal(readTask, winner); // Prove that it was canceled via the correct CancellationToken TaskCanceledException cancelled = await Assert.ThrowsAsync(() => readTask); Assert.Equal(cancellationSource.Token, cancelled.CancellationToken); ``` Is this by design, or simply something nobody has gotten around to, yet?

Recently we've stumbled upon particular issue of Windows 7 SP1 not supporting WebSockets natively, as they were introduced in Windows 8 / Server 2012. Check out https://github.com/SteamRE/SteamKit/issues/455 as a reference of original issue. Since there is managed implementation of websocket that is apparently **[already possible to be used on Windows](https://github.com/dotnet/corefx/blob/master/src/System.Net.WebSockets.Client/src/System.Net.WebSockets.Client.csproj#L7-L9)**, would it make sense to use it on Windows 7 as a platform that does not support WinSocket Windows stack natively? Or maybe it's already possible? Thank you in advance. 24250 area-System.IO System.IO.Directory.Delete should check for the name surrogate bit on reparse tags before deciding if it should enumerate directories with reparse points "Copied from internal bug 402782 System.IO.Directory.Delete recursive delete will not recurse through directory placeholders as it should (directory placeholders are a feature of GvFlt and the container filter). Christian Allred [callred] found that the Delete code ""will avoid trying to enumerate directories that are any kind of reparse point, rather than just name surrogates ... It should be fixed to check for the name surrogate bit on the reparse tag, same as rmdir /s does"" See: http://ddindex/?rightProject=mscorlib&file=system%5cio%5cdirectory.cs&line=1324) rmdir code // // We now enumerate and delete children iff: // directory and not reparse/namesurrogate // if (IsDirectory( find_data.dwFileAttributes ) && !(IsReparse( find_data.dwFileAttributes ) && IsReparseTagNameSurrogate( find_data.dwReserved0 ))) { ... // (Enumerate, deleting files and recursing into directories) ... } return RemoveDirectoryForce(pszDirectory); ... Rmdir /s checks the name surrogate bit using IsReparseTagNameSurrogate, which is in ntifs.h. It is defined as: #define IsReparseTagNameSurrogate(_tag) ( \ ((_tag) & 0x20000000) \ ) If you're doing a FindFirst/FindNext, the _tag value is the dwReserved0 field of the WIN32_FIND_DATA structure. That is how rmdir /s does its check: // // We now enumerate and delete children iff: // directory and not reparse/namesurrogate // if (IsDirectory( find_data.dwFileAttributes ) && !(IsReparse( find_data.dwFileAttributes ) && IsReparseTagNameSurrogate( find_data.dwReserved0 ))) { ... // (Enumerate, deleting files and recursing into directories) ... } return RemoveDirectoryForce(pszDirectory); ... Forgot to mention, the name surrogate bit is set on directory junctions, symlinks, etc. So having this check correctly identifies other types of reparse points that a recursive delete would not want to recurse in to." 24251 area-System.Console System.Console intellisense text not localized ![image](https://user-images.githubusercontent.com/8228359/30842958-e506af44-a23a-11e7-8679-de08a01ef3d2.png) 24252 area-System.Net Return condition directly instead of `if (condition) return true; els… Return condition directly instead of `if (condition) return true; else return false;` 24253 area-System.Net StatusCode in HttpRequestException "When the `EnsureSuccessStatusCode` method in the `HttpResponseMessage` throws a `HttpRequestException` exception it is not possible to determine the status code.

Now when trying to run the tests I get errors like: `Cannot find /home/sec/core/corefx/bin/tests/Canonicalization.Tests/netcoreapp-FreeBSD-Debug-x64/RunTests.sh` I'm missing something?

However it extends classes that implement the `IReadOnlyDictionary` interface, hence its usable from `ReadOnlyDictionary` but not from a normal `Dictionary`. Why isn't this extension method also available for the `Dictionary`? Wouldn't it be nice if it were? Perhaps another extension method that extends classes that implement the `IDictionary` interface ought to be inserted into the `CollectionExtensions` class? 24257 area-System.Net [ManagedHandler] Respect DNS TTL See #11224 for details on the issue 24259 area-System.Console FreeBSD: System.Console is not working right This is because terminfo database is missing in default installation.

This function may also be called multiple times (even after initialization) if the system does not have any installed printers. It is possible for multiple calls to this function to occur at the same time, which will result in unpredictable problems, because access to the hashtable is not synchronized in any way. This is unlikely to be a problem in real app code, because it can generally only occur during initialization, and because you need specific circumstances to trigger any issues. I have seen a local test run fail because of this. 24269 area-System.Drawing Enable ImageAttributes tests which pass on Unix System.Drawing.

(They boil down to `IntPtr Ptr`) In the full framework, these types of things are allowed, and (at least personally) used heavily in certain interop scenarios to help with native code interfaces that use a lot of templates. Loading the assembly via `AssemblyLoadContext.Default.LoadFromAssemblyPath` and calling `GetTypes` on it results in the following ReflectionTypeLoadException: > Unable to load one or more of the requested types.

The file may contain multiple CA certificates. The certificate(s) must be in PEM format. Normally curl is built to use a default file for this, so this option is typically used to alter that default file. curl recognizes the environment variable named 'CURL_CA_BUNDLE' if it is set, and uses the given path as a path to a CA cert bundle. This option overrides that variable. This provides a global way to provide custom CA for all dotnet application. It avoids applications breaking and having to implement their own. This is in particular useful in corporate environments where the https proxy is signed by a custom CA. @stephentoub @davidsh @geoffkizer @wfurt @karelz 24282 area-System.Data Enlisting in Ambient transactions is not supported " using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew)) { SqlCommand cmd = new SqlCommand(""ProcedureName"", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue(""Name"", ""upendra""); cmd.Parameters.AddWithValue(""EmailId"", ""a@a.com""); cmd.Parameters.AddWithValue(""MobileNumber"", ""384747848""); con.Open(); cmd.ExecuteNonQuery(); scope.Complete(); } **Error: Enlisting in Ambient transactions is not supported**" 24285 area-Infrastructure Enable CI for RHEL.6 24288 area-System.Net Use ManagedHandler in managed ClientWebSocket ClientWebSocket's managed implementation currently has its own basic Socket-based code for establishing a websocket connection. This change switches it to use ManagedHandler instead, and in doing so benefits from improvements made to ManagedHandler thus far and in the future. For example, currently the managed ClientWebSocket doesn't support ClientWebSocketOptions.Proxy or ClientWebSocketOptions.Credentials, but since ManagedHandler does, now the managed ClientWebSocket does, too. As part of this, there are several additional commits: - Making some tweaks to how ManagedWebSocket works: not using the ArrayPool for receive buffers (doing so ends up not being particularly useful in real scenarios and ends up draining the corresponding pool bucket for other users of it), and reducing spurious completions to try to return complete received messages when possible. - Reducing some unnecessary allocations from ClientWebSocketOptions. - Fixing several tests that were either unreliable or super long running. cc: @geoffkizer, @Priya91, @wfurt, @anurse Fixes https://github.com/dotnet/corefx/issues/23152 24291 area-Serialization Cache regexes for assembly name check in DataContract "Not sure how often `IsAssemblyFriendOfSerialization(Assembly)` is being hit but it looks like at least multiple times.

This includes a ReadOnlyMemory overload. This required a pushing of readonly memory right through the layers. This is in the effort to simplify and remove old code from SslStream and modernise the internals. It vastly simplifies the chained method calls, (byte[] buffer, int offset, int count becomes ReadOnlyMemory buffer). It also removes a lot of duplicated bounds checks because it's taken care of in the memory struct. If the changes look close to good I will be happy to start the benchmarking process. Cheers Tim 24296 area-System.Memory Memory and ReadOnlyMemory validation errors not matching "**Updated as per the suggestion of a create method** **Updated with design from @stephentoub which allows all cases to be covered** **Updated with design change from @benaadams to allow type inference for T** **Put in namespace and removed the Create to leave only the Dangerous Create** **Added question around moving current Dangerous Create Method** # Rationale A major use case of [ReadOnly]Span/Memory is to replace handing around array buffers and their offsets and count. One of the major benifits of the design as I see it as it moves bounds checks out to where the buffer is created which is excellent. However when upgrading legacy code there seems to be a blocker in that stream defines the triplet to be ` public int SomeMethod(byte[] buffer, int offset, int count); ` This is normally then teamed up with checks on 1. ""is buffer null"" == null argument exception 2. ""is offset negative or past the end of the buffer?"" == argument out of range exception with offset as field referenced 3. ""is count > than buffer.length, or < 0 or count +offset > buffer.length"" == argument out of range exception The issue with the way it currently is, that for anything that takes that triplet you have to manually do validation on the inputs before creating a Memory or risk having exceptions with names that don't match. This causes double validation to take place, once in the legacy code and once in the Memory creation. As Memory is often used on the ""hot paths"" of code it is a penalty for using memory. # Proposal Add ""unsafe"" methods to create memory and readonly memory that avoid the extra checks. Then the checks can be maintained in the code with the same error messages and the double check penalty doesn't have to be paid. ``` c# namespace System.Runtime.InteropServices { public static class Span { public static Span DangerousCreate(T[] array, int start, int length); ... } // ... same for ReadOnlySpan public static class Memory { public static Memory DangerousCreate(T[] array, int start, int length); } // ... same for ReadOnlyMemory } ```` # Usage ``` csharp byte[] buffer; var span = Span.DangerousCreate(buffer, offset, count); // vs var span = Span.DangerousCreate(buffer, offset, count); ``` # Outstanding Questions Should the existing method ``` c# [MethodImpl(MethodImplOptions.AggressiveInlining)] [EditorBrowsable(EditorBrowsableState.Never)] public static Span DangerousCreate(object obj, ref T objectData, int length) ``` Be moved to the new types and should the IDE hiding be removed? # References #24295 The Code this came up in (It means an extra validation path without it) Below no longer matters as the legacy code can maintain it's own named validation. ~~~Survey of the Async methods on classes you can see there are a couple of classes that don't conform but mostly it does.~~ |Class|ArrayName|Start|Length| |---|---|---|---| |FileStream|buffer|offset|count| |NetworkStream|buffer|offset|count| |BufferedStream|buffer|offset|count| |MemoryStream|buffer|offset|count| |StreamReader|buffer|index|count| |StreamWriter|buffer|index|count| |Stream|buffer|offset|count| |SslStream|buffer|offset|count| " 24298 area-System.Globalization "Tests under ""System.Globalization.Tests"" failed with ""Xunit.Sdk.TrueException""" System.Globalization.Tests.RegionInfoPropertyTests.DisplayName failed Detail: https://ci.dot.net/job/dotnet_corefx/job/master/job/osx10.12_release/3216/testReport/System.Globalization.Tests/RegionInfoPropertyTests/DisplayName_name____en_US____expected____United_States___/ Configuration: osx10.12_release MESSAGE: ~~~ Exit code was 131 but it should have been 42\nExpected: True\nActual: False ~~~ STACK TRACE: ~~~ at System.Diagnostics.RemoteExecutorTestBase.RemoteInvokeHandle.Dispose() in /Users/dotnet-bot/j/workspace/dotnet_corefx/master/osx10.12_release/src/CoreFx.Private.TestUtilities/src/System/Diagnostics/RemoteExecutorTestBase.cs:line 189 ~~~ 24303 area-Infrastructure Nobody but the developer should ever modify a GIT-tracked file.

Before we make that move we wanted to let folks know and give everyone a chance to speak up if there are any issues with moving. @dotnet/dnceng note that this will require updating our CI and official build machines. Please let me know what needs to happen for that to proceed. @karelz what set of alias' would be best to ping on this issue to raise awareness? 24321 area-Serialization Move XmlSerializer CodeGen from SGen to S.P.Xml.

Apologies if the answer is obvious, but I'm attempting to use a .NET Framework library (ZedGraph) that uses System.Drawing in my .NET Core 2 application and am having difficulties doing so. I added a reference to the new System.Drawing.Common package, but while it lets me use System.Drawing classes (like Graphics) it doesn't seem to transfer to the .NET Framework library I'm using. If I attempt to call a method in the library that takes in or returns a System.Drawing object such as Graphics, I get a compile error like the following: ``` CS7069: Reference to type 'Graphics' claims it is defined in 'System.Drawing', but it could not be found ``` Any clue what's going on? I tried recompiling the library to .NET Framework 4.5.1 (it was previous compiled for 3.5), to no avail. Thanks! Steps to reproduce: 1. Create a ,NET Core 2 class library 2. Add references to System.Drawing.Common and ZedGraph 3. Call a ZedGraph method whose signature involves a System.Drawing class, such as this: `new ZedGraph.GraphPane().Draw(out System.Drawing.Graphics g);` 24333 area-System.Text Regex performance compare with other programming languages There is a [mariomka/regex-benchmark](https://github.com/mariomka/regex-benchmark) repo that run regex benchmark for different programming languages.

Due to an build configuration problem the code that calls this callback was #ifdefed out in the .NET Core 2.0 release. This was fixed months ago but the fix has not made it into the release branches. The result is that EventCounters can't be turned on (that is if you signal to the EventSource that you want EventCounter data, it is ignored). This makes the type useless. This PR merges the fix from the master branch for this issue. It also fixes a number of races associated with the code that happened to be fixed in the same PR as well as beefed up the testing. The change is safe because it only affect EventCounter (or its testing), and currently EventCounter is pretty broken . 24343 area-System.Memory Add SpanExtensions.AsVector # Final/Approved Proposal https://github.com/dotnet/corefx/issues/24343#issuecomment-349418624 ```c# namespace System.Numerics { public struct Vector { // Existing API public Vector(T[] values); // Proposed API public Vector(Span values); } } ``` # Original Proposal It's quite common to want to convert a Span to Vector.

Fix #24339 @shmao @zhenlan @mconnew 24346 area-System.Runtime S.R.Intrinsics.X86 for .NET Standard? I've been loosely following the S.R.Intrinsics.X86 feature; apologies if this has been discussed before. As far as I know, S.R.Intrinsics.X86 requires support both from the hardware and from the CLR. Currently, the `IsSupported` properties indicate whether hardware support is present. This allows users to write code like this: ```csharp if (Sse2.IsSupported) { // fast path } else { // slow path } ``` The S.R.Intrinsics.X86 package is currently only available for `netcoreapp2.1`. This means if users want to target .NET Standard, they have to compile two versions of their library; one for .NET Core 2.1 and one for .NET Standard: ```csharp #if NETCOREAPP2_1 if (Sse2.IsSupported) { // fast path } else { #endif // slow path #if NETCOREAPP2_1 } #endif ``` Could the package be changed to target .NET Standard and the `IsSupported` properties be changed to indicate whether both hardware support and CLR support is available? Then users could simply target .NET Standard and any environment that has the right hardware and CLR would automatically take the fast path, without users having to compile their library individually for every CLR that supports the feature now or in the future. 24347 area-Infrastructure Update build to clang/llvm 3.9 Update scripts, docs and build pipeline docker images to clang/llvm/lldb 3.9 24352 area-System.Net SSLStream : Removed sync lock method "Looking at the code, because this method is basically never actually blocked on (only if a renegotiation takes place during a write) there is no need for a second ""sync"" method.

It's one of the more valuable concurrent collection types. However, unbounded collections aren't always desirable. For example, consider wanting to use a concurrent queue for object pooling. If you want to ensure you don't store more than N objects, this is difficult or impossible to achieve efficiently with `ConcurrentQueue`, which will automatically grow its storage to store the item being added if there's insufficient room. `ConcurrentQueue`, however, is actually implemented as a wrapper for a bounded queue, internally called `ConcurrentQueue.Segment`. https://github.com/dotnet/corefx/blob/9c468a08151402a68732c784b0502437b808df9f/src/System.Collections.Concurrent/src/System/Collections/Concurrent/ConcurrentQueue.cs#L820 In essence, `ConcurrentQueue.Segment` provides the bounded queue behavior, and `ConcurrentQueue` layers on top of that unbounded semantics. We should clean up the `Segment` APIs and expose it as ```C# namespace System.Collections.Concurrent { public sealed class BoundedConcurrentQueue { public BoundedConcurrentQueue(int capacity); // capacity must a power of 2 that's >= 2 public int Capacity { get; } public int Count { get; } public bool IsEmpty { get; } public bool TryEnqueue(T item); public bool TryDequeue(out T item); } } ``` The current implementation is fast, and is able to achieve that speed in part by eschewing some functionality that would weigh it down non-trivially, e.g. enumeration. That's why it doesn't implement any interfaces like `IEnumerable` or `IReadOnlyCollection` that would force us to add such behavior and slow it down. This collection would be very specialized and used purely for its ability to have items enqueued and dequeued quickly. (Methods like TryPeek, ToArray, CopyTo, GetEnumerator, etc., all require the ability to look at data in the queue without removing it, and in the current implementation, that requires marking the segment as ""preserving for observation"", which means nothing will ever be removed from the queue; this has the effect of continuing to allow enqueues until the segment is full, but since dequeues don't end up removing data, at that point nothing further can be enqueued, even if everything is dequeued. `ConcurrentQueue` deals with this simply by creating a new segment, but that doesn't work for the segment itself.)" 24366 area-Infrastructure GenerateDepsJson task failed with ArgumentException "I did a clean, sync, build locally and hit this (it succeeded on a subsequent attempt): ``` c:\Users\stoub\Source\Repos\corefx\src\src.builds(30,5): error MSB4018: The ""GenerateDepsJson"" task failed unexpectedly. c:\Users\stoub\Source\Repos\corefx\src\src.builds(30,5): error MSB4018: System.ArgumentException: Can not add property runtimes/win-x64/lib/netcoreapp2.0/mscorlib.dll to Newtonsoft.Json.Linq.JObject.

The `BuildBagOfCerts` is hardwired to use `X509Store` (user/machine store). I'd like to do my own handling of Certificates in my application. I would thus like a new virtual method `X509Certificate2Collection BuildBagOfCerts(KeyInfoX509Data keyInfoX509Data, CertUsage certUsageType)` in both `SignedXml` and `EncryptedXml` that I can use to do my own handling. As `CertUsage` is internal, this would either need to be public, or a simple `bool needsPrivateKey = false` to indicate that we need the private key, or omit it since it's clear which class needs which. SignedXml already has a private `BuildBagOfCerts` method which could call into it's virtual method, and EncryptedXml only calls it in `DecryptEncryptedKey`. Proposal: ```cs public class SignedXml { protected virtual X509Certificate2Collection BuildBagOfCerts(KeyInfoX509Data x509Data) { return Utils.BuildBagOfCerts(x509Data, CertUsageType.Verification) } private X509Certificate2Collection BuildBagOfCerts() { X509Certificate2Collection collection = new X509Certificate2Collection(); if (KeyInfo != null) { foreach (KeyInfoClause clause in KeyInfo) { KeyInfoX509Data x509Data = clause as KeyInfoX509Data; if (x509Data != null) collection.AddRange(BuildBagOfCerts(x509Data)); } } return collection; } } public class EncryptedXml { protected virtual X509Certificate2Collection BuildBagOfCerts(KeyInfoX509Data x509Data) { return Utils.BuildBagOfCerts(x509Data, CertUsageType.Decryption) } public virtual byte[] DecryptEncryptedKey(EncryptedKey encryptedKey) { // snip... kiX509Data = keyInfoEnum.Current as KeyInfoX509Data; if (kiX509Data != null) { X509Certificate2Collection collection = BuildBagOfCert(kiX509Data); foreach (X509Certificate2 certificate in collection) // snip... } } ``` 24371 area-System.Data Data.SqlClient : Intermittent Kerberos issues on Linux Hi, I'm using the new IntegratedAuthentication feature in the SqlClient (version 4.4 of the Data.SqlClient package and dotnetcore 2.0) on RHEL7 in a docker image.

"To attach a client certificate to the request one could write following code on the client side: ```c# var cert = //TODO - load certificate var requestHandler = new HttpClientHandler(); requestHandler.SslProtocols = SslProtocols.Tls12; requestHandler.ClientCertificateOptions = ClientCertificateOption.Manual; requestHandler.ClientCertificates.Add(cert); HttpClient client = new HttpClient(requestHandler); HttpResponseMessage response = client.GetAsync(""https://www.example.com/api/values"").Result; response.EnsureSuccessStatusCode(); ``` In asp.net core 2.0 server side, one could write following code to extract the certificate (typically in a middleware component): ```c# var cert = this.HttpContext.Connection.GetClientCertificateAsync().Result; ``` The above 'cert' variable will be non-null if client attached a certificate that has a private key in it (though private key portion is not transmitted to the server). However if the client attached only a public portion of the certificate to requestHandler.ClientCertificates.Add(cert) call, the server side will return null for the extracted certificate. If I added a client certificate to HttpClientHandler (and set it to Manual, which means no other certificate should be inspected for sending a client certificate), it is clear what my intent is. During the call execution, it should have thrown an error because I added a file that does not include a private key. Am I wrong to expect this behavior?

The primary reason for this is performance. The standard Reflection APIs are too slow to be used in the code paths targeted by these library authors, and though codegen has a large upfront cost it performs considerably better when amortized over the lifetime of the application. This approach generally works well, but the .NET Framework is considering scenarios where it must operate in environments which do not allow codegen. This renders ineffective the existing performance improvement techniques used by these library authors. We are uniquely positioned to provide a set of APIs which can cover the majority of scenarios traditionally involving reflection-based codegen. The general idea is that library authors can rely on the APIs we provide to work correctly _both_ in codegen-enabled _and_ in codegen-disallowed environments. Alternatively, the library authors can detect at runtime whether codegen is enabled, and if so they can use their existing highly-optimized codegen logic, falling back to the new API surface if codegen is disallowed. # Sample API surface ```csharp namespace System.Reflection { public delegate ref TField FieldAccessor(object target); public delegate ref TField FieldAccessor(ref TTarget target); /// /// Provides factories that can be used by serializers, formatters, and DI systems /// to perform reflection-like activities in performance-critical code paths. /// [SecurityCritical] public static class ReflectionServices { public static bool IsCodegenAllowed { get; } /* * FIELD ACCESSORS, GETTERS, AND SETTERS */ public static FieldAccessor CreateFieldAccessor(FieldInfo fieldInfo); public static FieldAccessor CreateFieldAccessor(FieldInfo fieldInfo); public static Func CreateFieldGetter(FieldInfo fieldInfo); public static Func CreateFieldGetter(FieldInfo fieldInfo); public static Func CreateFieldGetter(FieldInfo fieldInfo); public static Action CreateFieldSetter(FieldInfo fieldInfo); public static Action CreateFieldSetter(FieldInfo fieldInfo); // TTarget must not be value type; field must be an instance field. public static Action CreateFieldSetter(FieldInfo fieldInfo); /* * PARAMETERLESS OBJECT CREATION */ public static Func CreateInstanceFactory(Type type); public static Func CreateInstanceFactory(); /* * PARAMETERFUL OBJECT CREATION */ public static Func CreateInstanceFactory(ConstructorInfo constructorInfo); public static Func CreateInstanceFactory(ConstructorInfo constructorInfo); public static Delegate CreateInstanceFactoryTyped(ConstructorInfo constructorInfo, Type delegateType); /* * PROPERTY GETTERS AND SETTERS * TODO: How would indexed properties be represented? Using the normal method invocation routines? */ public static Func CreatePropertyGetter(PropertyInfo propertyInfo); public static Func CreatePropertyGetter(PropertyInfo propertyInfo); public static Func CreatePropertyGetter(PropertyInfo propertyInfo); public static Action CreatePropertySetter(PropertyInfo propertyInfo); public static Action CreatePropertySetter(PropertyInfo propertyInfo); // TTarget must not be value type; property must be an instance property. public static Action CreatePropertySetter(PropertyInfo propertyInfo); /* * METHODS */ public static Func CreateMethodInvoker(MethodInfo methodInfo); // If instance method, 'delegateType' must be open over 'this' parameter. public static Delegate CreateMethodInvoker(MethodInfo methodInfo, Type delegateType); /* * EVENTS */ public static Action CreateEventSubscriber(EventInfo eventInfo); // Event must be an instance event. public static Action CreateEventSubscriber(EventInfo eventInfo); public static Action CreateEventUnsubscriber(EventInfo eventInfo); // Event must be an instance event. public static Action CreateEventUnsubscriber(EventInfo eventInfo); } } ``` # Goals and non-goals * These APIs **are not** geared toward standard application developers who are already comfortable using the existing Reflection API surface. They are instead geared toward advanced library developers who need to perform Reflection operations in performance-sensitive code paths. * These APIs **must** work in a codegen-disallowed execution environment. (Are there exceptions?) * These APIs **do not** need to cover all scenarios currently allowed by the existing methods on `MethodInfo` and related types. For example, constructors that take `ref` or `out` parameters are sufficiently rare that we don't need to account for them. They can be invoked via the standard Reflection APIs. * These APIs **do not** need to have the same observable behavior as using the Reflection APIs; e.g., we may determine that these APIs should not throw `TargetInvocationException` on failure. But these APIs **must** provide consistent behavior regardless of whether they're running within a codegen-enabled or a codegen-disallowed environment. * Delegate creation **does not** need to be particularly optimized since there will be many checks performed upfront and we will ask callers to cache the returned delegate instances. However, once the delegates are created their invocation **must** be faster than calling the existing Reflection APIs. (Exception: if codegen is disallowed, then delegate invocation **should** be faster than calling the existing Reflection APIs wherever possible, and it **must not** be slower.) * It is an explicit **goal** to get serialization library authors to prefer this system over hand-rolling codegen for most member access scenarios. The selling points of this API would be ease of use (compared to hand-rolling codegen), performance, and the ability to work in a wide variety of execution environments. * It is an explicit **non-goal** to have performance characteristics equal to or better than a library's own custom codegen. For example, a DI system might choose to codegen a single method that both queries a service provider to get dependency instances and calls `newobj` on the target constructor. Such a system will always outperform these generalized APIs, but the API performance should be good enough that library authors would be generally satisfied using them over Reflection as a fallback in these scenarios. * These APIs **do not** need to support custom implementations of `MemberInfo`. Only support for CLR-backed members is required. 24394 area-System.Net "UWP HttpListener Read_Disposed_ReturnsZero test failed with ""The text associated with this error code could not be found.""" https://mc.dot.net/#/user/stephentoub/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/ead0778f7763f6852cd3f7124a9838950a39033b/workItem/System.Net.HttpListener.Tests/analysis/xunit/System.Net.Tests.HttpRequestStreamTests~2FRead_Disposed_ReturnsZero(transferEncodingChunked:%20True) ``` Unhandled Exception of Type System.Net.Http.HttpRequestException Message : System.Net.Http.HttpRequestException : An error occurred while sending the request. ---- System.Exception : The text associated with this error code could not be found.

I have a background in gamedev, and while it might be some time before Unity uses Core I wanted to contribute early! A common pattern in game dev to keep lists of objects of a certain type so they can be quickly iterated over eg to call some Update function. Objects register / deregister when created / destroyed. A direct implementation would be: ```C# void OnCreate() { All.Add(this); } void OnDestroy() { All.Remove(this); } ``` However, when a (part of) the world gets destroyed, lots of objects deregister at once. Each Remove has to move over the backing array. A common way to prevent this additional move is to use a remove with a swap back: ```C# All[index] = All[All.Count - 1]; All.RemoveAt(All.Count - 1); ``` Unreal engine has specific API's for their ""List"" Implementation to do a swap remove: https://docs.unrealengine.com/latest/INT/API/Runtime/Core/Containers/TArray/RemoveAtSwap/index.html I think it could be helpful to introduce the following extension methods: ```C# class ListExtensions { public void RemoveAtUnordered(this List list, int index); public void RemoveUnordered(this List list, T element); public void RemoveAllUnordered(this List list, Predicate match); public void RemoveRangeUnordered(this List list, int index, int count); } ``` Implementing them as extension methods prevents code bloat as lists are instantiated quite often. The naming uses Unordered instead of Swap because I think it communicates the difference vs a normal remove more clearly. **Benchmarks** List of N items. 10% of items are removed at random indices. The Small value type is 16 bytes. The large value type is 64 bytes. **RemoveAt**, Best case scenario if you know the index beforehand: ``` ini BenchmarkDotNet=v0.10.9, OS=Windows 10 Redstone 2 (10.0.15063) Processor=Intel Core

dramatic. The larger the stored item the worse the extra memory copy becomes. -RemoveUnordered on ref types is at best ~10% faster than Remove. Do note however that the worst case is hit if the items are added FIFO - as they would be in a common use case in Unity. If they are, the benchmarks look quite similair to the RemoveAt benchmark. An unordered remove guarantees performance is consistent. -RemoveAllUnordered is 10-50% faster in these benchmarks.

The existing ArraySegment-based methods were added as extension methods, and thus we added the new methods as extensions, too. Feedback was provided that these would be better as instance methods. However, we can't just add the new overloads as instance methods; we would also need to add the existing signatures as instance methods, effectively obsoleting the extensions. That's because of how the C# compiler binding works; once it finds an appropriate instance method, it'll no longer consider extension methods, and so the new methods as instance methods can result in compilation errors for existing uses of the existing extensions: an array segment can be implicitly converted to a memory, so it can use the new APIs, but then there will be a different return type (`ValueTask` instead of `Task`), and any usage of that return type other than `await` can fail to compile. Thus code like `Task t = s.ReceiveAsync(arraySegment, socketFlags);` will now fail to compile due to trying to convert a `ValueTask` to `Task`. So, two choices: 1. Leave the new methods as extensions. 2. Make the new methods be instance methods, and also add corresponding instance methods for the existing extensions. We need to make and address this for 2.1; otherwise we'll implicitly do (1), since that's what's in https://github.com/dotnet/corefx/pull/24431. 24443 area-System.Threading Please add Task continuation function with async await "`Task` class was made before async/await syntax so I understand why there are `ContinueWith` function exist.

Please add `Dictionary.Capacity` property or an `EnsureCapacity` method so that that you can. ## Rationale MSBuild, are resizing multiple times during Add that they cannot avoid without recreating the dictionary: https://github.com/Microsoft/msbuild/issues/2587. Another case came up in an Azure service profile today, where a dictionary was being copied into another dictionary which had already been constructed and resize CPU and allocation cost was high. ## Proposal (old) ```c# public partial class Dictionary : ... { public Dictionary(int capacity) { } // existing constructor public int Capacity { get { } set { } } } ``` The name `Capacity` is chosen to match the parameter name of the existing constructor. Setting Capacity to `value` causes the Dictionary to ensure it can have up to `value` elements without resizing. Behind the scenes if `value` is less than the existing capacity it calls Resize to increase the backing storage to the smallest Prime that is not less than the requested `value`. The getter is probably not terribly useful (debugging?) but a setter without a getter is strange. ## Discussion Implementation of this looks like it will be straightforward, not significantly increase the instantiated size of Dictionary's, and not affect code paths that do not call it. The resizing codepath obviously already exists, although right now it is never given a desired size: it starts with doubling. 24447 area-System.Threading Current CancellationToken?

Usually this is when I'm calculating expiration dates for web tokens where the expiration property is the number of seconds since the Unix epoch (see https://en.wikipedia.org/wiki/Unix_time for definition). ## Proposed API ```diff namespace System { public struct DateTime { + public static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc); } public struct DateTimeOffset { + public static readonly DateTimeOffset UnixEpoch = new DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero); } } ``` ## Example Usage ```c# public class TokenIntrospectionResponse { public int ExpirationInSeconds { get => (int)((ExpirationUtc - DateTime.UnixEpoch).TotalSeconds); set => ExpirationUtc = DateTime.UnixEpoch.AddSeconds(value); } public DateTime ExpirationUtc { get; set; } } ``` 24452 area-Infrastructure [release/1.1.0] Backport PreferInbox=true to dead-end packages Many of our packages are no longer produced in 2.0.0 because they were absorbed into .NETStandard. As a result, there is no new version of those packages with fixes that were only put into the 2.0 codebase. One example of such a change is https://github.com/dotnet/corefx/pull/18307 (issue https://github.com/dotnet/corefx/issues/15112). There may be others. We should backport these changes if they apply to any package that we're no longer shipping in 2.0 so that folks get the changes. When backporting we should also make sure to ship the complete set of packages impacted. 24453 area-System.Net Removed obsolete System.Net.Http NETFX related files "Due to PR #23611, the master branch no longer builds a NETFX binary for System.Net.Http. Instead this is now handled only in the release/2.0.0 branch as part of the ""NETStandard support package"". This effectively means that we have already stopped OOB'ing System.Net.Http on .NET Framework platforms as of .NET 4.7.1 since that version of .NET Framework supports all NETStandard2.0 APIs. And .NET Framework versions prior to that (4.6.x, etc.) are handled with the OOB System.Net.Http.dll that is part of the NETStandard support package." 24454 area-System.Net SslStream not working with ephemeral keys This issue was opened as result of the discussion in issue #19888. I have a .net core 2.0 application which hosts a service and secures it via SSL. My key material is a a key pair where I have the certificate and the private keys in two files. So I load the cert and the keys from disk and use the X509Certificate2.CopyWithPrivateKey method to construct a certificate with a private key. That works as it should.

One minimal test would be to launch a child process, and check that some string's GetHashCode() gives a different result than it does in the test's own process (maybe with a retry in case of 4 billion : 1 bad luck) https://github.com/dotnet/coreclr/blob/da8b7181dbe362fbfe64c7ef72ff3a4a7db68f24/src/mscorlib/src/System/String.Comparison.cs#L971 Ideally we would also test that Dictionary resorts to randomized hash codes when it's hitting a lot of collisions. This is hard to test without somehow generating a lot of strings that collide with the non randomized hash code. I suggest using reflection to force `HashHelpers.HashCollisionThreshold` to zero and then check that Comparer on the dictionary changes to the standard EqualityComparer.Default. https://github.com/dotnet/coreclr/blob/da8b7181dbe362fbfe64c7ef72ff3a4a7db68f24/src/mscorlib/src/System/Collections/Generic/Dictionary.cs#L454 Dictionary is the only collection that specially uses non randomized string hashcodes.

This means people who want cancellation currently need to add a using statement: ```cs using (cancellationToken.Register(smtpClient.SendAsyncCancel)) { await smtpClient.SendMailAsync(message); } ``` Extension method for convenience, in case you want to operate on the original Task without wrapping in an async state machine: ```cs public static Task SendMailAsync(this SmtpClient client, MailMessage message, CancellationToken cancellationToken) { if (client == null) throw new ArgumentNullException(nameof(client)); if (message == null) throw new ArgumentNullException(nameof(message)); var cancellationRegistration = cancellationToken.Register(client.SendAsyncCancel); var task = client.SendMailAsync(message); task.ConfigureAwait(false).GetAwaiter().OnCompleted(cancellationRegistration.Dispose); return task; } ``` The difficulty is that there's no guarantee that `SendMailAsync` will continue to be implemented in terms of `SendAsync` under the covers and that `SendAsyncCancel` will have any effect. Rather than an extension method, it's more future-proof to bring the responsibility of this coupling much closer to where it belongs: as a detail inside the implementation of `SmtpClient`. ## Proposal I propose adding these two overloads, copies of the existing overloads but appending a `CancellationToken` parameter: ```diff class System.Net.Mail.SmtpClient { public Task SendMailAsync(string from, string recipients, string subject, string body) + public Task SendMailAsync(string from, string recipients, string subject, string body, CancellationToken cancellationToken) public Task SendMailAsync(MailMessage message) + public Task SendMailAsync(MailMessage message, CancellationToken cancellationToken) } ``` Implementation would likely be straightforward, with the non-cancellable overloads delegating to the cancellable ones and the `SendCompletedEventHandler` disposing the cancellation registration. 24477 area-System.Net .Net WebClient.DownloadData api result in different behavior in some kind of project @treeicnliu commented on [Sat May 27 2017](https://github.com/dotnet/core/issues/664) I got different http packages by fiddler4 when i call the same fucntion WebClient.DownloadData(string uri) api with the same param uri on web proj and console proj.

Core i5 with 8 GB memory laptop, SSD 120 GB. Both the app and the server run on same machine (localhost). Under windows the same code requires about 2 sec (provided that the server is also running under windows). When loading a table of about 150 000 rows (about 10 columns) from sql server I get about 300 sec time! Smaller tables also loaded in such a big time (proportionally to the number of rows). All requests are sync (async versions never used). This happens for both the EF approach or with direct using of SQLDataReader, so the problem is NOT in the EF. As a workaround I simply run sqlcmd tool with the sql request as a separate process and parse its output as a cvs file. This takes about 2 sec (not 300 sec) for the same tables. MS SQL server was installed in a pretty ""normal"" way following the official instructions (https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu). I use typical code for DB reading in C# by EF where-style request or just with SQLDataReader: using (var connection = new SqlConnection(DataConString)) { var command = new SqlCommand(query, connection); command.Connection.Open(); var reader = command.ExecuteReader(); while (reader.Read()) parse_the_line(reader); } My gues is that Core 2.0 handles the connection in some bad manner (eg. disconnects and connects on each row of table) or there's something in deserialization (though I think just any kind of deserialization woldn't be that bad) or maybe Core 2.0 switches to async methods under the hood (which in turn set a kind of timer and wakes on receiving each piece of data) or so on, but these are only my guesses. Maybe it's somehow connected with the well known MS SQL server bug (feature?) under linux: sqlcmd tool becomes toooo slow when the output is redirected to a file by '>' in the command line. (Note: I don't redirect the output when using sqlcmd tool as a workaround, just read the process output line by line.) So maybe Core 2.0 works with MS SQL server the same bad way as sqlcmd tool does when redirected to a file. But again these are only my guesses. **Upd:** The problem is on Core side, not with the SQL server. I just tried connecting to Windows-hosted server, the problem still remains (about 300 sec for 150K rows). Though the same code under Windows works fine (about 2-3 sec). --- @Ataden commented on [Sat Aug 12 2017](https://github.com/dotnet/core/issues/802#issuecomment-321964793) I confirm such an issue.

At least with our mail provider. Framework: asp.net core Version: 2.0 Example1: var client = new SmtpClient(""asmtp.mail.hostpoint.ch"", 587); client.UseDefaultCredentials = false; client.Credentials = new NetworkCredential(""our_usr"", ""our_pwd""); client.EnableSsl = true; //... Create MailMessage in variable ""message"" client.Send(message); Example2: var client = new SmtpClient(""asmtp.mail.hostpoint.ch"", 587); client.Credentials = new NetworkCredential(""our_usr"", ""our_pwd""); client.UseDefaultCredentials = false; client.EnableSsl = true; //... Create MailMessage in variable ""message"" client.Send(message); Result: Example1 works like a charm, while Example2 fails with this Exception: ""System.Net.Mail.SmtpException: 'Mailbox unavailable. The server response was: You are not authenticated. Try to activate SMTP Authentication in your mail'"" There is really no difference, just the switch of that 2 lines of code. We tested this in a clean new asp.net core test project. We simply could reproduce it as often as we want, just by switching this 2 lines. VERY weird ! :) Our provider for the mail is ""Hostpoint"" from Swizzerland (see host above in SmtpClient() constructor). Its not possible for me (security reasons) to offer you more information, like users, passwords, etc. so you can test. Sorry. But maybe the problem exists with other Mail providers like GMail etc. and you can reproduce it there. I didnt tested that. Maybe it is some really special thing with our Mail provider. But it seems definitelly worth for you to look at, i think. Or at least for me, to inform you about that :) Just want let you know about that strange issue.

"I am seeing following issue in build and opening System.Runtime.Extension solution in VS 2017 Community edition IDE. About three (plus) weeks back these issues were not seen. Last weekend, I sync'd my fork with latest code in dotnet/master and since then these issues have been happening consistently. Not only on my branch for #22409 but also on the master branch in my fork. I also recreated my local git repo, but no luck. Issues are, a. On firing ""build.cmd"" / ""build-managed.cmd"" execution is stuck at below line seen on console for about 10 - 15 mins and, at that time network activity kicks in. I see download at about 300kBps from the server ""blob.byaprdstr06a.store.core.windows.net"". Roughly 50MB of stuff is downloaded and then the build proceeds. The line on console after which download begins is as below: ```D:\WinCPP\corefx\packages\Microsoft.TargetingPack.NETFramework.v4.6.1\1.0.1\lib\net461\sysglobl.dll (Microsoft.TargetingPack.NETFramework.v4.6.1.1.0.1) -> D:\WinCPP\corefx\bin\AnyOS.AnyCPU.Release\netfx\netcoreapp\sysglobl.dll``` b. On opening System.Runtime.Extension in VS 2017 Community edition IDE, it gets stuck at ""Preparing Solution"" for similar duration (10 - 15 mins). In this case too, network activity kicks in and devenv.exe appears to be downloading data from same server ""blob.byaprdstr06a.store.core.windows.net"". Alt+Tab into VS 2017 Community IDE at that point gives a pop up at lower right saying VS is busy and information has been sent to ""Visual Studio Experience Improvement Program""... Both the above issues repeat on each run of build command or each time the solution is opened in VS IDE. Primarily the problem is that 50MB per build (or even on opening VS) translates to 500 MB if I were to build / open VS for about 10 times during one coding session; a number that can be easily exceeded. Secondly, the 10-15 min delay holds up build / opening VS IDE. Kindly help. I am wondering if the download is not able to write some sort of "".complete"" file because of which the entire download is repeated every time I run build command or open the solution? This could very well be an issue with my setup that got introduced after I rebased about a month's data from dotnet/master. @karelz @weshaggard created this issue as per our discussion on gitter." 24550 area-System.Net HttpListener cannot recognize Websocket request from firefox "When establishing websocket connection, firefox sends such `Connection` header: `Connection: keep-alive, Upgrade` and `System.Net.HttpListener` can't recognize the `Upgrade` It can be tested with inserting this test case ```csharp [InlineData(""Connection: keep-alive, Upgrade\r\nUpgrade: websocket"", true)] ``` to the `IsWebSocketRequest_GetProperty_ReturnsExpected` test of `HttpListenerRequestTests.cs`" 24551 area-Infrastructure Need to build new 2.0.x Microsoft.NETCore.Platforms package We've made changes to the RID graph in the release/2.0.0 servicing branch.

However, we aren't producing a `2.0.x` version of the `Microsoft.NETCore.Platforms` package that contains these changes.

When the libssl1.0.0 and libssl1.0.2 packages are both installed on a machine, `System.Security.Cryptography.Native.Openssl` will preferentially load `libssl.so.1.0.0`. `System.Net.Http.Native`, however, loads `libcurl.so`, which in turn loads `libssl.so.1.0.2`. ### Repro Some combination (as yet undetermined; the repro is ""open PowerShell 6.0.0-beta.8, wait a while"") of interacting with the members of these assemblies, or of passing SSL contexts between System.Net.Http and System.Security.Cryptography.Openssl will trigger a segmentation violation and subsequent termination. ### Dependency Graph ``` * System.Net.Http.Native * libcurl.so.4 * libssl.so.1.0.2 * System.Security.Cryptography.Native.Openssl * libssl.so.1.0.0 ``` ### Resolution Not sure. * Probe for libssl symbols, fall back to dlopen if none are found? * Prefer `libssl.so.1.0.2`?" 24553 area-System.Net SNI API for SslStream ## Rationale The SNI extension allows for multiple hostnames to be served from a single IP address/port combo. This is needed for Kestrel to be able to be a true web facing internet server using TLS. The client side already supports sending a hostname so requires no change. The serverside should have a callback that gives the correct certificate/chain depending on a host name or returns null if none are available. If no certificate is returned the handshake should fail. This requires the ALPN Api to be completed first. ## API Shape ``` c# namespace System.Net.Security { public class SslServerAuthenticationOptions { public ServerCertificateSelectionCallback ServerCertificateSelectionCallback { get; set; } } public delegate System.Security.Cryptography.X509Certificates.X509Certificate ServerCertificateSelectionCallback(object sender, string hostName); } ``` Additional API information: - When host name could not be found the `hostName` value will be `null` when callback is called - `hostName` will never be an empty string - When caller returns null certificate we will throw `AuthenticationException` **Open questions:** - `ReadOnlySpan` vs. `string` for `hostName` - for server API it might be appropriate to make callback with `ReadOnlySpan` - this way server does not have to make two allocations on each request (1 for UTF8 conversion and 1 for IDN conversion) - server could potentially do conversion beforehand and then do byte compare - for client we chose hostName but in the client case it is less important and should be more user friendly - If we choose `ReadOnlySpan`, should we add API to convert to `string`?

Some tests make silent assumption about IPv6 and they fail if system is not configured to meet that. This is unpleasant for anybody from community to run tests and get good pass. The easy repro for Linux is: sysctl -w net.ipv6.conf.all.disable_ipv6=1 ./build-tests.sh The expected behavior would be that tests needing IPv6 would be skipped.

What's the magic of 32739? Q2: `225 <= lastLength <= 247, 32740 <= path.Length <= 32762` throws `System.IO.PathTooLongException`, meanwhile `Directory.Exists` prints `False`. However I can see the first few level directories are created(not all directories), which means the creation is partially done with an exception. Why? Q3: `248 <= lastLength <= 251, 32763 <= path.Length <= 32766` cases are almost the same as those in Q2, except the exception is `System.IO.DirectoryNotFoundException`, why? `lastLength > = 252, path.Length >= 32767` fails with `System.IO.PathTooLongException`, no directory is created, which is as expected.

Details and Usage from previously proposed API ## Rationale These API allow for encoding of a Span\ into UTF-8 Base64 encoded span (binary to text operation) and decoding of a UTF-8 Base64 encoded span to Span\ (text to binary operation). They will be used by SignalR (for example [here](https://github.com/SignalR/SignalR/blob/master/src/Microsoft.AspNet.SignalR.Core/Infrastructure/DefaultProtectedData.cs#L22), [here](https://github.com/SignalR/SignalR/blob/master/src/Microsoft.AspNet.SignalR.Core/Infrastructure/DataProtectionProviderProtectedData.cs#L40), and [here](https://github.com/aspnet/SignalR/blob/dev/src/Microsoft.AspNetCore.SignalR.Common/Internal/Encoders/Base64Encoder.cs)). A prototype of the API is available in corefxlab: https://github.com/dotnet/corefxlab/tree/master/src/System.Binary.Base64 Part of https://github.com/dotnet/corefx/issues/24174 Previous review: https://github.com/dotnet/apireviews/tree/master/2017/06-16-System.Text.Buffers ## Usage For valid input data: ```C# Span input; // input buffer to be encoded containing binary data Span encodedBytes = new byte[Base64.BytesToUtf8Length(input.Length)]; OperationStatus status = Base64.BytesToUtf8(input, encodedBytes, out int consumed, out int encodedBytesCount); // status == OperationStatus.Done // encodedBytes.Length == encodedBytesCount // consumed == input.Length ``` ```C# Span input; // input buffer to be decoded containing textual data Span decodedBytes = new byte[Base64.Utf8ToBytesLength(input.Length)]; OperationStatus status = Base64.Utf8ToBytes(input, decodedBytes, out int consumed, out int decodedByteCount); // status == OperationStatus.Done // decodedBytes.Length >= decodedByteCount // consumed == input.Length ``` Using these new APIs, we can take the following code snippet (from [here](https://github.com/aspnet/SignalR/blob/dev/src/Microsoft.AspNetCore.SignalR.Common/Internal/Encoders/Base64Encoder.cs)): ```C# public byte[] Decode(byte[] payload) { var buffer = new ReadOnlyBuffer(payload); LengthPrefixedTextMessageParser.TryParseMessage(ref buffer, out var message); return Convert.FromBase64String(Encoding.UTF8.GetString(message.ToArray())); } ``` And re-write it as follows (if we want to keep the input/output as byte arrays): ```C# public byte[] Decode(byte[] payload) { var buffer = new ReadOnlyBuffer(payload); LengthPrefixedTextMessageParser.TryParseMessage(ref buffer, out var message); // assume message.Span is UTF-8 encoded (for instance, using the upcoming UTF8 encoder APIs) Span bytes = new byte[Utf8ToBytesLength(message.Span.Length)]; Base64.Utf8ToBytes(message.Span, bytes, out int consumed, out int written); return bytes.Slice(0, written).ToArray(); } ``` For potentially invalid (or incomplete) input, the user can check the returned status. For example, change the above code as follows: ```C# Span bytes = new byte[Utf8ToBytesLength(message.Span.Length)]; OperationStatus status = Base64.Utf8ToBytes(message.Span, bytes, out int consumed, out int written); return status == OperationStatus.Done ? bytes.Slice(0, written).ToArray() : ; } ``` ## Proposed API ```C# // System.Memory.dll namespace System.Buffers.Text { public static class Base64 { public static OperationStatus BytesToUtf8(ReadOnlySpan bytes, Span utf8, out int consumed, out int written, bool isFinalBlock = true); public static OperationStatus BytesToUtf8InPlace(Span buffer, int bytesLength, out int written, bool isFinalBlock = true); public static int BytesToUtf8Length(int bytesLength); // public static int BytesToUtf8Length(ReadOnlySpan utf8, bool isFinalBlock); public static OperationStatus Utf8ToBytes(ReadOnlySpan utf8, Span bytes, out int consumed, out int written, bool isFinalBlock = true); public static OperationStatus Utf8ToBytesInPlace(Span buffer, out int consumed, out int written, bool isFinalBlock = true); public static int Utf8ToBytesLength(int utf8Length); // public static int Utf8ToBytesLength(ReadOnlySpan utf8, bool isFinalBlock); } } ``` **Note:** OperationStatus is the same as TransformationStatus (https://github.com/dotnet/corefx/issues/22412). ## Open Questions ### 1 For computing length, another approach could be to add the following overloads, which give the ""actual"", precise length: ```C# public static int BytesToUtf8Length(ReadOnlySpan utf8, bool isFinalBlock); public static int Utf8ToBytesLength(ReadOnlySpan utf8, bool isFinalBlock); ``` The behavior of the currently proposed APIs is similar to the ones listed above for when isFinalBlock is true. For example: ```C# // input = ABC DEF G BytesToUtf8Length(input, false); // returns 8 BytesToUtf8Length(input, true); // returns 12 == BytesToUtf8Length(input.Length) ``` ### 2 To extend the functionality of the currently proposed APIs to include new line support (for example, for the MIME variant of Base64), we could add the following overloads that take a ParsedFormat parameter: ```C# public static OperationStatus BytesToUtf8(ReadOnlySpan bytes, Span utf8, out int consumed, out int written, ParsedFormat format, bool isFinalBlock = true); public static OperationStatus BytesToUtf8InPlace(Span buffer, int bytesLength, out int written, ParsedFormat format, bool isFinalBlock = true); public static OperationStatus Utf8ToBytes(ReadOnlySpan utf8, Span bytes, out int consumed, out int written, ParsedFormat format, bool isFinalBlock = true); public static OperationStatus Utf8ToBytesInPlace(Span buffer, out int consumed, out int written, ParsedFormat format, bool isFinalBlock = true); public static int BytesToUtf8Length(int bytesLength, ParsedFormat format); public static int Utf8ToBytesLength(int utf8Length, ParsedFormat format); ``` Which creates a dependency on ParsedFormat (https://github.com/dotnet/corefx/issues/24607) The usage would then look like: ```C# ParsedFormat format = new ParsedFormat('N', 76); int requiredSize = Base64.BytesToUtf8Length(source.Length, format); Span encodedBytes = new byte[outputSize]; Base64.BytesToUtf8(source, encodedBytes, out int consumed, out int written, format); ``` ### 3 Should we rename `Utf8ToBytesLength(int utf8Length)` to `Utf8ToBytesMaxLength` to indicate it isn't the precise length (but rather could be a few bytes larger)? Same with `BytesToUtf8Length(int bytesLength)`?

For this, it needs to use proxy settings. There are two options either we configure each call to use proxy server or set proxy setting machine wide. Setting WinHTTP proxy configuration is easier than WinINet. However .net core process uses wininet as default proxy policy. How can I set it to default to WinHTTP than WinINet for the whole app rather than changing in each WinHttpHandler? _Copied from original issue: dotnet/core#1023_ 24575 area-System.Numerics Make BigInteger BigEndian-friendly The current state of BigInteger accepts a `byte[]` (and now a `ReadOnlySpan`) as a little-endian signed value, and the writer APIs (`ToByteArray()` and `TryWriteBytes`) only emit as a signed little-endian value. Various wire protocols may dictate either of 1) an unsigned value in transmission or 2) big-endian transmission. Both of these protocol choices result in the application/library needing to understand the translation of protocol bytes to BigInteger bytes, at a cost to performance and risk to reliability. ## Proposal ```C# partial class BigInteger { // Augment existing public BigInteger( ReadOnlySpan value, bool isBigEndian=false, bool isUnsigned=false) => throw null; // Augment existing public bool TryWriteBytes( System.Span destination, out int bytesWritten, bool isBigEndian=false, bool isUnsigned=false) => throw null; // New overload. public byte[] ToByteArray(bool isBigEndian=false, bool isUnsigned=false) => throw null; } ``` Since the span-based APIs have not yet released, I propose that they be augmented with the default-value-parameters. For `ToByteArray` an overload will have to be added, but the existing method can just forward to `ToByteArray(false, false)`. A byte[]-based ctor overload may also be warranted if Span and BigInteger may have different velocities to .NET Framework (or the implicit cast causes too much cognitive overload). ## Behavior Given `byte[] data = { 0xFE, 0x80 };` * `new BigInteger(data, isBigEndian: false, isUnsigned: false)` => `(short)0x80FE` => `-32514` * `new BigInteger(data, isBigEndian: true, isUnsigned: false)` => `(short)0xFE80` => `-384` * `new BigInteger(data, isBigEndian: false, isUnsigned: true)` => `(int)0x000080FE` => `33022` * `new BigInteger(data, isBigEndian: true, isUnsigned: true)` => `(int)0x0000FE80` => `65152` When the most significant byte of the input data does not have the most significant bit set the `isUnsigned` value has no meaning. Emitting values (reminder, parameter order is `isBigEndian, isUnsigned`; `isBigEndian` label removed to prevent bulleted list from gaining line-wraps) * `new BigInteger(-32514).ToByteArray(false, isUnsigned: false)` => ` {0xFE, 0x80 }` * `new BigInteger(-32514).ToByteArray(true, isUnsigned: false)` => `{ 0x80, 0xFE }` * `new BigInteger(-32514).ToByteArray(false, isUnsigned: true)` => exception * `new BigInteger(-32514).ToByteArray(true, isUnsigned: true)` => exception * `new BigInteger(33022).ToByteArray(false, isUnsigned: false)` => `{ 0xFE, 0x80, 0x00 }` * `new BigInteger(33022).ToByteArray(true, isUnsigned: false)` => `{ 0x00, 0x80, 0xFE }` * `new BigInteger(33022).ToByteArray(false, isUnsigned: true)` => `{ 0xFE, 0x80 }` * `new BigInteger(33022).ToByteArray(true, isUnsigned: true)` => `{ 0x80, 0xFE }` 24576 area-Infrastructure Update CentOS 6 docker image This update fixes problem with git not supporting https protocol 24577 area-System.Net Change System.Net.Http to throw exception for HTTPS -> HTTP redirects Currently, .NET Core will ignore automatic HTTPS -> HTTP redirects in HttpClientHandler. This is already a different behavior from .NET Framework (which allows automatic HTTPS -> HTTP redirects). .NET Core is different from .NET Framework in this manner in order to provide a more secure behavior pattern. However, currently .NET Core simply ignores the HTTPS -> HTTP redirect. It leaves the final response with the 3xx response. This has caused a lot of developer confusion when troubleshooting issues. This issue is now tracking to make a behavior change to .NET Core. Instead of ignoring HTTPS -> HTTP redirects, it will instead throw an HttpRequestException with a suitable inner exception and error message. 24579 area-System.Diagnostics Port System.Diagnostics.PerformanceCounters to .NET Core This change adds System.Diagnostics.PerformanceCounters to .NET Core.

This issue is ONLY happening when the SQL Server and the .NET Core application is running on the same linux machine (Ubuntu). I created a simple application which does a .ToList() on 2 tables (one with 500 records, another with 10,000) Running the .NET Core application on my local computers, connecting to the SQL Server remotely, I get the following results: ``` Loaded (Table 1) 500 in 851.00 ms Reloading context.

For whatever reason, there seems to be a huge send queue from SQL to my application, which leads me to believe EF Core may be very slow materializing the data from sql - SQL sends the data perfectly fine.

These are sufficient for normal arithmetic needs but are somewhat difficult to use by callers who need to perform interlocked manipulation of fields that are intended to be bitwise flags. As an example, consider ASP.NET's internal `CancellationTokenHelper` class, which uses several calls to `Interlocked.CompareExchange` within a `switch` statement in order to mimic performing flag manipulation of a field. (http://referencesource.microsoft.com/#System.Web/Util/CancellationTokenHelper.cs,71) Or consider how `System.Threading.Task` uses `Interlocked.CompareExchange` in a loop to mimic the `InterlockedAnd` operation. (http://referencesource.microsoft.com/#mscorlib/system/threading/Tasks/Task.cs,865) While it's possible for callers to implement interlocked bitwise operations in terms of interlocked arithmetic operations, it's a bit difficult to get right, and the framework should make this easier for the power developers who need it. ## Proposed API additions ```csharp namespace System.Threading { public static class Interlocked { public static int And(ref int location1, int value); public static long And(ref long location1, long value); public static int Or(ref int location1, int value); public static long Or(ref long location1, long value); public static int Xor(ref int location1, int value); public static long Xor(ref long location1, long value); } } ``` ## Behavior Like their arithmetic counterparts, these APIs perform the operation atomically and return the _original_ value to the caller. At the IL level, these APIs can be implemented in terms of the existing APIs on the `Interlocked` class. Ideally the JITter could special-case when the caller discards the return value without inspection, and this would turn in to a `lock and` or similar instruction instead of a standard `lock cmpxchg`. The proposed APIs should have the same memory fence semantics that the arithmetic operations have today. (I believe it's a full fence?) ## Samples The `System.Threading.Task` code from earlier, as it exists today: ```csharp // Atomically clear the END_AWAIT_NOTIFICATION bit SpinWait sw = new SpinWait(); while (true) { int oldFlags = m_stateFlags; int newFlags = oldFlags & (~TASK_STATE_WAIT_COMPLETION_NOTIFICATION); if (Interlocked.CompareExchange(ref m_stateFlags, newFlags, oldFlags) == oldFlags) break; sw.SpinOnce(); } ``` Could be written as such with the new primitives (n.b. caller doesn't care about return value, so JIT optimization described earlier could kick in): ```csharp // Atomically clear the END_AWAIT_NOTIFICATION bit Interlocked.And(ref m_stateFlags, ~TASK_STATE_WAIT_COMPLETION_NOTIFICATION); ``` 24594 area-System.IO NamedPipeClientStream depends on WaitNamedPipe, which is not supported in Windows Containers `NamedPipeClientStream.TryConnect` calls into native `WaitNamedPipe` first to make sure the pipe is available and only then into native `CreateNamedPipeClient`. The problem is that currently `WaitNamedPipe` is not supported from inside of Windows Containers (however `CreateNamedPipeClient` works ok). It fails with `ERROR_FILE_NOT_FOUND`. As such, managed code using `NamedPipeClientStream` is broken in Windows Containers due to the ordering of the calls. This includes Docker.Dotnet library and projects depending on it. Since both these calls happen in a loop which is making sure that the given timeout is not exceeded, we could swap them and call `WaitNamedPipe` only if `CreateNamedPipeClient` fails in a predicable manner first.
