I was able to reproduce this locally on old Ubuntu 14 and running ALL tests in loop. This did non repro while running only single test or running them in sequence. I was able to collect traces suggesting that in some cases send() is called after recv failed. I added Task.Wait() to increase changes that sent is actually done when we try to receive. With this change I was able to run the test for a day where it would fail in about one hour before. My original change had 1s wait. However after one day, it failed again with new debug message that the sending task did not complete in 1s time. This is Azure VM instance where it is not clear what else is happening at the same time. I feel it would be better to be more liberal and possibly wait longer than have random failures. I bumped wait() timeout to 3s and receive timeout to 1s. This is still best guess but the tests are still running right now. When I get 3-5 days without failure I'll update this PR. I just wanted to get it out so people can comment on it. fixes #17681 24616 area-System.IO Switch WaitNamedPipe and CreateNamedPipeClient invocation ordering. We need to do this as WaitNamedPipe is not supported in Windows Containers. With this change, CreateNamedPipeClient will be called first, with call to WaitNamedPipe as a fallback only.

Not discoverable; you need to use the Span property to find them 2. Span can't be used in an `async` method; so to use them you need to create a second method and call that ### Proposal Include the second method as extensions on `{ReadOnly}Memory` that passes through to the Span ```csharp public static class MemoryExtensions { // Span methods converted to Memory extension public static void CopyTo(this Memory memory, Memory destination) => memory.Span.CopyTo(destination.Span); public static void CopyTo(this ReadOnlyMemory memory, Memory destination) => memory.Span.CopyTo(destination.Span); public static bool TryCopyTo(this Memory memory, Memory destination) => memory.Span.TryCopyTo(destination.Span); public static bool TryCopyTo(this ReadOnlyMemory memory, Memory destination) => memory.Span.TryCopyTo(destination.Span); public static void Fill(this Memory memory, T value) => memory.Span.Fill(value); // Array extension as per Span extension public static void CopyTo(this T[] array, Memory destination) => array.CopyTo(destination.Span); // Valid? via Owned memory? public static ReadOnlyMemory AsReadOnlyMemory(this string text); // Discoverable conversions as per Span public static Memory AsMemory(this ArraySegment arraySegment) => arraySegment; public static Memory AsMemory(this T[] array) => array; // Span extension pass-throughs public static int IndexOf(this Memory memory, byte value) => memory.Span.IndexOf(value); public static int IndexOf(this Memory memory, ReadOnlyMemory value) => memory.Span.IndexOf(value.Span); public static int IndexOf(this ReadOnlyMemory memory, byte value) => memory.Span.IndexOf(value); public static int IndexOf(this ReadOnlyMemory memory, ReadOnlyMemory value) => memory.Span.IndexOf(value.Span); public static int IndexOf(this Memory memory, T value) where T : struct, IEquatable => memory.Span.IndexOf(value); public static int IndexOf(this Memory memory, ReadOnlyMemory value) where T : struct, IEquatable => memory.Span.IndexOf(value.Span); public static int IndexOf(this ReadOnlyMemory memory, T value) where T : struct, IEquatable => memory.Span.IndexOf(value); public static int IndexOf(this ReadOnlyMemory memory, ReadOnlyMemory value) where T : struct, IEquatable => memory.Span.IndexOf(value.Span); public static int IndexOfAny(this Memory memory, byte value0, byte value1) => memory.Span.IndexOfAny(value0, value1); public static int IndexOfAny(this Memory memory, byte value0, byte value1, byte value2) => memory.Span.IndexOfAny(value0, value1, value2); public static int IndexOfAny(this Memory memory, ReadOnlyMemory values) => memory.Span.IndexOfAny(values.Span); public static int IndexOfAny(this ReadOnlyMemory memory, byte value0, byte value1) => memory.Span.IndexOfAny(value0, value1); public static int IndexOfAny(this ReadOnlyMemory memory, byte value0, byte value1, byte value2) => memory.Span.IndexOfAny(value0, value1, value2); public static int IndexOfAny(this ReadOnlyMemory memory, ReadOnlyMemory values) => memory.Span.IndexOfAny(values.Span); public static bool SequenceEqual(this Memory first, ReadOnlyMemory second) => first.Span.SequenceEqual(second.Span); public static bool SequenceEqual(this ReadOnlyMemory first, ReadOnlyMemory second) => first.Span.SequenceEqual(second.Span); public static bool SequenceEqual(this Memory first, ReadOnlyMemory value) where T : struct, IEquatable => first.Span.SequenceEqual(value.Span); public static bool SequenceEqual(this ReadOnlyMemory first, ReadOnlyMemory value) where T : struct, IEquatable => first.Span.SequenceEqual(value.Span); public static bool StartsWith(this Memory memory, ReadOnlyMemory value) => memory.Span.StartsWith(value.Span); public static bool StartsWith(this ReadOnlyMemory memory, ReadOnlyMemory value) => memory.Span.StartsWith(value.Span); public static bool StartsWith(this Memory memory, ReadOnlyMemory value) where T : struct, IEquatable => memory.Span.StartsWith(value.Span); public static bool StartsWith(this ReadOnlyMemory memory, ReadOnlyMemory value) where T : struct, IEquatable => memory.Span.StartsWith(value.Span); } ``` ### Notes Items that change length can't be replicated due to the backing store e,g, `AsBytes`, `NonPortableCast` ### Question Is a string conversion possible?

In full .NET framework (4, 4.6) it works. The same code in .net core 2 throws `NullReferenceException`. The problem has something to do with column mappings (`SqlBulkCopy.ColumnMappings`). When we set mappings using indexes, everything works. When we set mappings using column names, NRE is thrown. See the attached example.

" 24650 area-System.ComponentModel System.ComponentModel.Win32Exception doesn't match ref contract I encountered an issue while working with the corefx libraries using custom tooling. It's possible that the following scenario is allowed, but here's what I'm seeing. In M.Win32.Primitives the Win32Exception class has the GetObjectData method defined in the ref contract. The method was removed from the implementation in https://github.com/dotnet/corefx/commit/9eafffc6054c8f039d788465621bcfd49a379ca1. Assemblies in corefx build against the ref contract and have a memberref to a non existing member. It is still implemented by a base type, but shouldn't this cause method binding errors? Is this a case that is allowed by CIL spec or is this actually an error hidden by coreclr? Edit for clarity: This isn't a binding question, it's more of a CIL decoding question. The particular error I encountered has a MemberReference token to the method in question. AFAIK a CIL decoder shouldn't need to do method resolution while trying to decode the stream. Edit: The method is also explicitly overridden by Win32Exception in the netstandard contract. 24652 area-System.Runtime UriTemplate from System.ServiceModel "It would be nice to be able to do something like this: ```csharp private static readonly UriTemplate _activationTemplate = new UriTemplate(""license/activate/{licenseKey}""); public async Task ActivateAsync(LicenseActivationRequest activationRequest) { var requestUrl = _activationTemplate.BindByPosition(_httpClient.BaseAddress, activationRequest.LicenseKey); var serialized = JsonConvert.SerializeObject(activationRequest, _serializerSettings); var content = new StringContent(serialized, Encoding.UTF8, ""application/json""); using (var response = await _httpClient.PutAsync(requestUrl, content).ConfigureAwait(false)) { // ... } // ... } ``` #7983 asks about the same thing, and the response was: > Thank you for the suggestion. It is a good idea in general about having templates, but we think it belongs where it is in WCF and is not generally applicable to .NET Core. I think that comment misunderstands the use case for `UriTemplate`s. There's nothing WCF-specific about `UriTemplate`. In fact, the code above is taken from a service client implementation that interacts with an ASP.NET Core web service. `UriTemplate` is used to safely build URLs. It's safer, and more capable than string concatenation.

[EDIT] Making code link inline for readability by @karelz 24675 area-System.Drawing System.Drawing.Common needs netfx and netstandard configurations Right now it has only netcoreapp configuration. A netstandard configuration that simply throws would allow netstandard libraries that don't use drawing to reference the upcoming compat pack. Ideally it can be built properly for netstandard in which case this would allow netstandard libraries to use drawing. It also needs a netfx configuration to make a shim System.Drawing.Common that redirects to System.Drawing, so such netstandard libraries could also work on .NET Framework. fyi @weshaggard @terrajobst 24677 area-System.Net Disposing Socket during Socket.Receive behaves badly on *nix "### Repro app: ```C# using System; using System.Net; using System.Net.Sockets; using System.Threading.Tasks; namespace SocketInvalidArg { class Program { static void Main(string[] args) { using (var serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)) { serverSocket.Bind(new IPEndPoint(IPAddress.Loopback, 5000)); serverSocket.Listen(512); var i = 0; try { for (;; i++) { using (var clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)) { clientSocket.Connect(IPAddress.Loopback, 5000); var acceptSocket = serverSocket.Accept(); Task.WaitAll(Task.Run(() => ReadInput(acceptSocket)), Task.Run(() => acceptSocket.Dispose())); } } } catch { Console.Write(""Failed after #{0} iterations"", i); throw; } } } static void ReadInput(Socket socket) { try { Console.WriteLine(""Calling socket.Receive""); var count = socket.Receive(new byte[256]); Console.WriteLine(""Called socket.Receive with count = {0}"", count); } catch (ObjectDisposedException) { Console.WriteLine(""Socket.Receive threw ODE""); } catch (SocketException ex) when (ex.SocketErrorCode != SocketError.InvalidArgument) { Console.WriteLine(ex + Environment.NewLine + ex.SocketErrorCode); } } } } ``` ### Actual Behavior (macOS 10.12 and Ubuntu 16.04) On macOS and Linux, Socket.Recieve() either throws an ""Invalid argument"" SocketException: ```$ dotnet run Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Socket.Receive threw ODE Calling socket.Receive Failed after #12 iterations Unhandled Exception: System.AggregateException: One or more errors occurred.

Having hash based predictible Guids (v5) which could be derived from string and don't collide with random based guids (v4) can be extremely useful in some scenarios. RFC4122 proposes a standard around UUIDs to address that. # Possible Use Cases Here are some of the use cases I see: * Slug projection to Guid primary key (eliminate the need to maintain an index for that matter, allows using the primary key which is usually the clustered index to get the data) * Mixing potentially identical ids but namespaced in the same keyspace. * Reducing a composite key to a single Guid. * More broadly every scenario where a hash is a good fit (not from a security perspective) but where we need guids. # Proposed API ``` public partial struct Guid { public static readonly Guid DnsNamespace // 6ba7b810-9dad-11d1-80b4-00c04fd430c8 public static readonly Guid UrlNamespace // 6ba7b811-9dad-11d1-80b4-00c04fd430c8 public static Guid NewGuid(); public static Guid NewUuidV1(); public static Guid NewUuidV4(); public static Guid NewUuidV5(string value, Guid namespace); public static Guid NewUuidV5(byte[] value, Guid namespace); } ``` # Details We would obviously keep the existing NewGuid() which in windows calls [`UuidCreate`](https://msdn.microsoft.com/en-us/library/windows/desktop/aa379205(v=vs.85).aspx). It seems that it uses UUID v4 under the hood. In addition we would add NewGuidV1, NewGuidV4 et NewGuidV5 methods.

The behavior of `..` with respect to symbolic links is platform dependent. On Windows, it removes the symbolic link element. On Linux, it removes an element of path that was resolved from the symbolic link. Examples: - Windows: If `C:\Users\All Users` is a symbolic link to `C:\ProgramData` then the canonical form of `C:\Users\All Users\..\foo` is `C:\Users\foo`. - Linux: If `/var/lock` is a symbolic link to `/run/lock` then the canonical form of `/var/lock/../foo` is `/run/foo`. On Linux it is not always possible to preserve symbolic links while simplifying `..`. In these cases `Path.GetCanonicalPath(string, bool)` will resolve the symbolic link regardless of the value of `preserveSymbolicLinks`. For the purposes of this API, NTFS Junction Points are considered to be like Linux bind mounts and are not considered to be symbolic links. Since most of the members of `Path` do not do I/O there might be some objection to adding `GetCanonicalPath` to `Path`. There is at least one existing method that does do I/O — `Path.GetTempFileName` — so it would not be the first. # Open Questions - How should `GetCanonicalPath` handle paths in `\\?\` and `\\.\`? - Maybe return a `\\?\` path if and only if the input path was in `\\?\`. - Maybe reject paths in `\\.\`. - What should `GetCanonicalPath` do if the path does not exist? - Maybe canonicalize the existing part and append the rest as canonicalized as possible. - Does Linux provide a mechanism for determining the actual casing of a file or directory name for files and directories that reside on a file system that is mounted in a case-insensitive mode? If it doesn't then the provided casing will have to be returned. # Related Issues - #1086 # See Also - [Relevant portion of .NET Core Design Reviews: MAX_PATH Limitations](https://youtu.be/lpa2OFauASM?t=2721) # Updates - Replace `SymbolicLinkOption` with `bool`. - Split out #25569" 24690 area-System.Diagnostics EventLogTests.DeleteLogTest failed on Win7 in CI https://mc.dot.net/#/user/dotnet-maestro-bot/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/0105300fc3ca40d98db157cea91b097c68de6627/workItem/System.Diagnostics.EventLog.Tests/analysis/xunit/System.Diagnostics.Tests.EventLogTests~2FDeleteLogTest ``` Windows.7.Amd64.Open-Debug-x64 Unhandled Exception of Type System.ComponentModel.Win32Exception Message : System.ComponentModel.Win32Exception : Access is denied Stack Trace : at System.Diagnostics.EventLogInternal.Clear() at System.Diagnostics.EventLog.Clear() at System.Diagnostics.EventLog.Delete(String logName, String machineName) at System.Diagnostics.EventLog.Delete(String logName) at System.Diagnostics.Tests.EventLogTests.DeleteLogTest() ``` 24694 area-System.Diagnostics [ExcludeFromCodeCoverageAttribute] should be applicable to assemblies Following up on https://github.com/Microsoft/vstest/issues/1050, https://github.com/Microsoft/testfx/issues/248, https://github.com/dotnet/corefx/issues/14488.

This advisory also provides guidance on what developers can do to update their applications correctly. Microsoft is aware of a security vulnerability in the public version of .NET Core where a malformed string request could cause an application to crash and lead to a denial of service. System administrators are advised to update their .NET Core runtimes to versions 1.0.7 and 1.1.4. Developers are advised to update their .NET Core SDK to version 1.1.4. ### Mitigation Factors .NET Core 2.0 is not affected by this issue. ,NET Core 1.x applications are only affected if running on Windows 10 or Windows 2016. ### Advisory FAQ #### How do I know if I am affected? Any application running against .NET Core 1.0.6 or lower versions, or 1.1.2 or lower versions is affected. The latest version of the .NET core runtime you have installed in your computer can be listed by running `dotnet --info`. Running that command produces an output similar to the following: ``` .NET Command Line Tools (2.0.2) Product Information: Version: 2.0.2 Commit SHA-1 hash: a04b4bf512 Runtime Environment: OS Name: Windows OS Version: 10.0.16299 OS Platform: Windows RID: win10-x64 Base Path: C:\Program Files\dotnet\sdk\2.0.2\ Microsoft .NET Core Shared Framework Host Version : 2.0.0 Build : e8b8861ac7faf042c87a5c2f9f2d04c98b69f28d ``` As this command only displays the latest version of the runtime installed (or the version set in the *global.json* file), it may hide the fact that you have a vulnerable runtime. A complete list of runtimes can be discovered by performing a directory listing in the install root directories. The default root directories are listed in the following table: | Operating System | Location | |------------------|-------------------| | Windows | C:\Program Files\dotnet\shared\Microsoft.NETCore.App\ | | macOS | /usr/local/share/dotnet/shared/Microsoft.NETCore.App/ | | [Supported Linux platforms](https://docs.microsoft.com/dotnet/core/linux-prerequisites#supported-linux-versions) | /usr/share/dotnet/shared/Microsoft.NETCore.App/ | Each runtime version is installed in its own directory, where the directory name is the version number. If you don't have a directory for 1.0.7 and 1.1.4, then any applications targeting 1.0 or 1.1 of .NET Core are vulnerable. Also, even if you have a directory for 1.0.7 and 1.1.4 present in your system, if you've deployed [self-contained applications](https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd) targeting the impacted versions, these applications are also vulnerable. #### How do I fix my affected application? Applications can be fixed by installing the latest .NET Core runtimes or SDKs. Typically, application servers only have runtime packages installed and developer machines have the SDKs installed. Installers for the runtimes can be downloaded from the [Runtime and SDK download archive](https://github.com/dotnet/core/blob/master/release-notes/download-archive.md). .NET Core 1.1.4 SDK installs both versions 1.0.7 and 1.1.4 of the .NET Core runtime. If you've built a [self-contained application](https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd), you must install the new runtime and SDK, recompile your application and redeploy. #### What if the update breaks my application? An application can be pinned to a previous version of the runtime by editing the [*application.runtime.config*](https://github.com/dotnet/cli/blob/ede74b6be1406ba0c086b6d5fc1a5d4eacff1f01/Documentation/specs/runtime-configuration-file.md#appnameruntimeconfigjson) file for that application. Set the framework version to the desired version and the `rollForward` property to `false`. These settings should be treated as a temporary measure and the application updated to work with the patched versions of the framework. Since the *application.runtime.config* file is an optional file, you may need to create one for each application and add it alongside the executable. ### Acknowledgments David Fernandez of [Sidertia Solutions](https://www.sidertia.com/Home) ### External Links [CVE-2017-8585](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8585) [Sidertia blog on their discovery](https://www.sidertia.com/Home/Community/Blog/2017/07/14/Microsoft-fixes-the-CVE-2017-8585-security-vulnerability-discovered-by-Sidertia-Team) _Version 1.1_ _Last Updated 2017-18-10_ 24704 area-System.Diagnostics compatibility consideration for UseShellExecute with Process.Start() "This is fresh start of topic related to #23705 and #24000 At least on Unix ""UseShell"" has standard meaning: shell is used to execute requested command. There are many examples - like Python's popen() or simply difference between execv() and system(). On Windows his has different meaning and implies to open file with default application. Unix implementation was recently updated to match Windows behavior. However that possibly creates backward compatibility problem. 2.0 has been released with using /bin/sh to match traditional Unix experience. Change in behavior can break existing usage of Process.Star() - and it did even in trivial case for corefx tests. /bin/sh is pretty much guarantied to exist on any normal Unix system but new helpers may not. Process.Start(new ProcessStartInfo { UseShellExecute = true, FileName =""ls""}) works with 2.0 but it does not work with current master branch on my system. Further more, Unix users would expect normal shell behavior. Following examples will succeed when running with dotnet 2.0 ``` static void Main(string[] args) { String cmd=""if [ -e /etc/passwd ] ; then echo yes ; else echo no; fi""; var startInfo = new ProcessStartInfo(cmd); startInfo.UseShellExecute = true; startInfo.CreateNoWindow = true; using (Process px = Process.Start(startInfo)) { px.WaitForExit(); Console.WriteLine(""cmd returned {0}"", px.ExitCode); } } ``` One can pass in fragments of shell code with 2.0. ``` test@net-chip:~/process$ dotnet run yes cmd returned 0 ``` another common use case is use if command pipeline and have shell handling it: ``` String cmd=""cat /etc/passwd|grep root""; test@net-chip:~/process$ dotnet run root:x:0:0:root:/root:/bin/bash cmd returned 0 ``` In this case shell will run each command in separate process and it will redirect output from cat to stdin of grep. This is pretty typical use. Last part is use of .profile and shell variables. When used with shell, for example ""echo $HOME"" would expand to home directory. When used without shell, it would be passed in as string. " 24705 area-System.Threading Add method to avoid TaskScheduler.UnobservedTaskException for a given Task Unobserved `Task` exceptions are propagated to the `TaskScheduler.UnobservedTaskException` event. There are cases where we want to be able to ignore the results of a task without triggering that event. For example, we have an extension method, `task.WithTimeout(TimeSpan)` which will throw a `TimeoutException` if a task doesn't complete before a specified time. In this case we want to ignore the results of the original task. Currently we use an extension method to ignore individual tasks: ```C# public static void Ignore(this Task task) { if (task.IsCompleted) { var ignored = task.Exception; } else { IgnoreAsync(task); } async void IgnoreAsync(Task asyncTask) { try { await asyncTask.ConfigureAwait(false); } catch { // Ignored. } } } ``` That method still has a cost, though, and ideally we would like to remove most of that cost. A method inside the framework to ignore the results of a task without needing to register/allocate a continuation would be beneficial here. 24706 area-System.Net Test that matching cookies are found after non-matching cookies Test case for #24368.

That will create reliability problems as well as it is unpleasant for anybody working on shared or production system. It would be better to document prerequisites and run tests when conditions are met. That would also mean checking or updating current CI images so we do not always skip runs due to lack of dependencies. We should also update documentation and explain what is needed for proper execution so anybody from community can successfully run the tests. 24709 area-System.ComponentModel Question about BindingList Hello, I have a question about `BindingList`. Is there any particular reason that the `RaiseListChangedEvents` property is not exposed via an interface like `IBindingList` or a new one called `IRaiseListChangedEvents`? I just ran into this today during work where I had a dynamic type created via `TypeBuilder` and an instance of `BindingList` where `T` was this dynamic type. Before adding a bunch of items, I wanted to turn off the list changed notifications and turn them back on after and also call a `ResetBindings`. So because I have a dynamic type I can't cast my list to `BindingList`, because I have no information about `T` during the writing of the program. If `BindingList` implements a new interface `IRaiseListChangedEvents`, then I can just cast the collection to that and access the property. Same goes for `ResetBindings`. I ended up creating an empty class deriving from `BindingList`, implementing a new interface with the needed properties/methods so I can access them even if `T` is dynamic and not known at compile time. What is the reason of not exposing these members as a new or as part of the existing interfaces?

@gabor182 24726 area-System.Runtime Question: How are unmanaged code libraries loaded as SafeHandles? "**How are C++ libraries loaded into SafeHandle() classes in .Net Core on Linux (or any platform)?** I am attempting to port an application to .Net Core. The application makes external calls to a C++ library. Before doing so, it loads the library into a SafeHandle. Windows platform: ``` [DllImport(""Kernel32"", CharSet = CharSet.Auto, BestFitMapping = false, SetLastError = true)] private static extern SafeLibraryHandle LoadLibrary(string fileName); ``` Posix platform (via Mono): ``` [DllImport(__Internal, CallingConvention = CCCdecl)] private static extern SafeLibraryHandle dlopen(IntPtr filename, int flags); ``` The class ""SafeLibraryHandle"" inherits from Microsoft.Win32.SafeHandles.SafeHandleZeroOrMinusOneIsInvalid. (The SafeHandleZeroOrMinusOneIsInvalid base class was added in .Net Core 2.0.) The Kernel32 LoadLibrary() works as expected when running in .Net Core on Windows. When running on Linux, the Mono method is called and fails as expected because there is no __Internal library available. From what I've found, Mono wraps the [Linux dlopen() command](http://man7.org/linux/man-pages/man3/dlopen.3.html) like [this](https://github.com/mono/mono/blob/master/libgc/gc_dlopen.c). I'm rather unfamiliar with loading/using unmanaged code. From what I can tell, the purpose of these SafeHandle classes is to load the library files into memory and turn them into disposable types. Since the SafeHandle base class exists in .Net Standard and is used in .Net Core, it seems like there should be way to load libraries on any platform. **So how should C++ libraries be loaded into SafeHandle() classes in .Net Core on Linux?**" 24727 area-System.Net [release/2.0.0] Port SmtpClient fixes to 2.0 cc @stephentoub Fixes #24485 Port of #24536 to release/2.0.0 branch 24728 area-System.IO Rename new Stream.Read/Write{Async} Span/Memory arguments to buffer We'd previously decided to name these source/destination, but we also have an overriding principle that we should adhere to names used in existing overloads if possible, and we should only use source/destination to help in cases where we need to make the direction clear.

I have the following scenario: I use a ConcurrentDictionary as the core of a simple memory cache. The Get function of the cache will look up the key, and check the value's timestamp to see if the entry is expired. If it is, I want to remove it from the dictionary. However, a different thread might have concurrently renewed the cache entry, thus making removal unnecessary. So I want to remove the entry, but only if it is still the same value as before. I am basically looking for TryUpdate, but with the updated value being ""not there"". Or to put it another way, I want ICollection.Remove(KeyValuePair) exposed and documented as a regular function. The implementation is actually trivial: ``` public bool RemoveIfValue(TKey key, TValue value) { if (key == null) throw new ArgumentNullException(nameof(key), SR.ConcurrentDictionary_ItemKeyIsNull); TValue throwAwayValue; return TryRemoveInternal(key, out throwAwayValue, true, value); } ``` This is basically a copy&paste of the explicit IDictionary.Remove implementation, but with separate arguments instead of a KeyValuePair, and exposed as a method accessible without casting. This can currently be worked around with this extension method: ``` public static bool RemoveIfValue(this ConcurrentDictionary self, TKey key, TValue value) { var asCollection = (ICollection>)self; return asCollection.Remove(new KeyValuePair(key, value)); } ```" 24771 area-System.Runtime Throw exception if SysConf fails in Environment.ProcessorCount This shouldn't happen in a valid configuration, but adding the exception to help highlight the problem with an invalid configuration.

For our netcoreapp build vertical we need to be able to build it against the latest version without needing to restore the older packages. This is for the build-from-source efforts which require us to build all the assets instead of restoring them. 24778 area-System.Net ManagedHandler: Protocol corruption if 100-continue is expected but not received ManagedHandler has the same 100-continue bug as CurlHandler: https://github.com/dotnet/corefx/issues/24435 100-continue is an inherent race condition. The client is waiting for a 100 response or a final response, but only for a given timeout. When the server sends the final response without a 100, it has no way of knowing if the client's timer has expired and it has already started sending data. This would be an ambiguous situation as the server wouldn't reliably know if the next bytes it received were the body it was promised or the headers for the next request. To prevent this ambiguity the client must always send the data it promised, or a chunked terminator, or close the connection. For small bodies it's worth sending it to avoid the cost of creating a new connection, but for large bodies is far more economical close the connection. ManagedHandler (and CurlHandler) does not send the the request body if it receives a final response rather than a 100 continue. This causes protocol corruption on the next request and it is rejected by the server (e.g. 400 Bad Request). Final status codes are common in authentication scenarios like when the user's request is rejected due to missing or insufficient permissions. The client can send a new request with the required credentials, and many clients do this automatically. See AuthenticationHandler. Workaround: Apps must disable ExpectContinue on every request with a body. The fix for ManagedHandler looks small, handling for ReceivedOtherStatusCode needs to be added to the switch here: https://github.com/dotnet/corefx/blob/08802ff9c877f7f75a82d6704d84d321e99eb5c8/src/System.Net.Http/src/System/Net/Http/Managed/HttpConnection.cs#L457-L462 Sending the data is the minimal fix, but consider sending only the chunked terminator or closing the connection for non-trivial request bodies. This can also avoid problems with un-buffered HttpContent objects that can't be sent twice. 24779 area-System.Runtime Adding tests for Random Hashing Fixes #24466 cc: @danmosemsft @stephentoub 24781 area-System.Net [WIP] Checking Master with true Outerloop 24782 area-Infrastructure Update ProjectNTfs, ProjectNTfsTestILC, Standard to rel-25916-00, rel-25916-00, preview1-25916-01, respectively (release/uwp6.0) 24788 area-System.Linq Add a single parameter, with return type `ValueTuple` overload for `Enumerable.Zip`?

To mitigate this, we simply change the default ExpectContinue == null behavior to be the equivalent of ExpectContinue == false rather than to be ""do whatever the platform decides"". This also more closely aligns with WinHttpHandler and ManagedHandler, where effectively the ""platform"" in those cases decides that the default is disabled. For ManagedHandler, currently we're mimicking behavior like that libcurl employed and may sometimes not send the full payload but still keep the connection open. Instead, make sure we either always send the full payload or close the connection.

Therefore if I am not mistaken we should check that the GCHandle is still allocated when we rehydrate it from a pointer handed in from unmanaged code? Also if it is null or deallocated, we don't want to throw an exception inside a Native callback because it can cause all kinds of havoc. 24792 area-System.Data SqlClient: OUTPUT clause causes exceptions to not get thrown until read "This scenario is a bit lengthy, so I'll load it into a gist: https://gist.github.com/benrr101/31628b57f1ab410090237c9018860e05 Basically what this boils down to is that if I `.ExecuteReader()` on a `SqlCommand` that has an `OUTPUT` clause in it, I don't get an exception from the query failing until I call `.Read()` on the `SqlDataReader` I gt back. For instance executing: ``` INSERT INTO [dbo].[testtable]([small_col]) VALUES (""this value will be truncated"") SELECT * FROM [dbo].[testtable] ``` ``` SqlDataReader reader = cmd.ExecuteReader(); // Doesn't throw reader.Read() // DOES throw ``` But executing: ``` INSERT INTO [dbo].[testtable]([small_col]) OUTPUT inserted.[small_col] VALUES (""this value will be truncated"") ``` ``` SqlDataReader reader = cmd.ExecuteReader(); // DOES throw reader.Read(); // Never executed ``` At this point I'm not sure if this is an expected behavior due to quirks in the TDS protocol or if it's a bug.

This causes problems when multiple clients try to connect before WaitForConnection{Async} is called; any number that's under the min listen limit applied by the OS will have their connections completed, even though Accept hasn't been called, and then when the socket is closed, the connections will all fail. This change moves the UDS creation to when the NamedPipeServerStream is created, deleting it when the NPSS is disposed. cc: @pjanotti, @JeremyKuhne, @jaredpar, @khyperia 24799 area-System.Net SSLStream Fixing GC Hole 24800 area-System.Net Remove dead code from System.Net.NetworkInformation PR addresses issue #17905, project **System.Net.NetworkInformation**.

This issue has been adressed in NETStandard20/UWP6.0 and the FCU, and it works if you target W10 build 16299 on a desktop. However, on W10M devices like the Lumia 640, the build and thus NETStandard20 is unavailable and everytime a connection is disrupted the app will crash. Could a fix for this be made available, preferably in the near future?

Running a .NET Core 2.0 CLI app on macOS 10.12.6. ClientWebSocket version is the latest I believe. When operating in a multi-threaded environment, I receive what looks like a C++ malloc exception. This appears to be happening when the remote host terminates the connection unexpectedly. I have locks on reads + writes so there is never more than one of each happening at once. When I make a call to either `SendAsync` or `ReceiveAsync` and the connection has been terminated unexpectedly, I receive the following error: ``` dotnet(75902,0x700010355000) malloc: *** error for object 0x7fe5669dbf20: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug ``` I can't say for certain whether or not the remote host has terminated the connection because I don't have a stack trace, but it is my suspicion as I know there is a rate limit on the web socket endpoint, and this issue only happens shortly after sustained requests exceed rate limit threshold. I can't think of any way of preventing this issue in user code (other than a rate limiter but that only stops a certain type of unexpected termination.) Adding a lock won't solve it because the the connection could be terminated between when I call ReceiveAsync and when ReceiveAsync reaches the point in native code where it breaks. 24822 area-System.IO Internal relative relationships for System.IO.Packaging.Package fail to load on Mono "Uri parsing on Mono has a quirk when parsing a Uri that if you pass `UriKind.RelativeOrAbsolute`, a forward slash `/` is treated as absolute while in .NET Framework this would be parsed as relative. This causes packaging to break when reading a package file (for a real example, see OfficeDev/Open-XML-SDK#249 where DocumentFormat.OpenXml fails to load documents on Xamarin) where internal relationships are managed by relative Uris. There are a few workarounds available (see www.mono-project.com/docs/faq/known-issues/urikind-relativeorabsolute/ for details): 1. Use a special `UriKind` defined by Mono when run on that runtime; ie `(UriKind)300` 2. Set an environment variable to force all Uri instances that start with a forward slash to be parsed as relative (`export MONO_URI_DOTNETRELATIVEORABSOLUTE=true`) ## Potential Fix There is a single instance of `UriKind.RelativeOrAbsolute` and it is while parsing internal relationships: https://source.dot.net/#System.IO.Packaging/System/IO/Packaging/InternalRelationshipCollection.cs,357. A potential fix to not require the environment variable would be to use `UriKind.Relative` when target mode is internal. ## Repro ```csharp using (var ms = new MemoryStream()) { using (var package = Package.Open(ms, FileMode.OpenOrCreate, FileAccess.ReadWrite)) { package.CreateRelationship(new Uri(""/target"", UriKind.Relative), TargetMode.Internal, ""type""); } ms.Position = 0; using (var package = Package.Open(ms, FileMode.OpenOrCreate, FileAccess.ReadWrite)) { var relationships = package.GetRelationships(); var relationship = Assert.Single(relationships); Assert.Equal(new Uri(""/"", UriKind.Relative), relationship.SourceUri); Assert.Equal(new Uri(""/target"", UriKind.Relative), relationship.TargetUri); Assert.Equal(TargetMode.Internal, relationship.TargetMode); } } ``` ## Expected Successfully retrieve relationships and have asserts pass ## Observed ``` Unhandled Exception when attempting to call `package.GetRelationships()`: System.ArgumentException: PackageRelationship target must be relative URI if TargetMode is Internal.

However, it does not clear the Authorization header so the redirected request will contain the original credentials. The original credentials may have been scoped to a specific host/url, but there’s no check on where the redirect will send those credentials to. The Authorization header needs to be cleared. Considering this request flow: 1. Initial request Get http://example.com/ -> 401, www-Authenticate: Basic 2. Resubmitted for auth Get http://example.com/ Authorization: Basic foo <-- Added by AuthenticationHandler -> 301, Location: http://microsoft.com/ 3. Resubmitted for redirect Get http://microsoft.com/ Authorization: Basic foo <-- Left over from the prior request The Authorization header needs to be cleared after step 2 so that it doesn’t get forwarded to the redirect destination. This code block could be used to clear the header, but it would need to be moved to the bottom of the method to run after the auth resubmits. https://github.com/dotnet/corefx/blob/6d3804c5d9edec46c85797701834bbb135c8500f/src/System.Net.Http/src/System/Net/Http/Managed/AuthenticationHandler.cs#L48-L54 Compare to the desktop stack: https://github.com/Microsoft/referencesource/blob/7de0d30c7c5ef56ab60fee41fcdb50005d24979a/System/net/System/Net/HttpWebRequest.cs#L5840 https://github.com/Microsoft/referencesource/blob/7de0d30c7c5ef56ab60fee41fcdb50005d24979a/System/net/System/Net/_AuthenticationState.cs#L318 Repro: Dotnet –version: 2.1.0-preview1-007228 Output for Non-ManagedHandler: “Auth header after redirect: “ Output for ManagedHandler: “Auth header after redirect: Basic Zm9vOmJhcg==” ``` using System; using System.Net; using System.Net.Http; using System.Text; using System.Threading.Tasks; namespace ConsoleApp16 { class Program { static void Main(string[] args) { var listener = new HttpListener(); listener.Prefixes.Add(""http://localhost:5001/""); listener.Start(); RunServer(listener); RunClient().Wait(); } private static async Task RunClient() { var handler = new HttpClientHandler(); handler.Credentials = new NetworkCredential(""foo"", ""bar""); var client = new HttpClient(handler); var response = await client.GetStringAsync(""http://localhost:5001/basic""); Console.WriteLine(response); } private static async void RunServer(HttpListener listener) { while (true) { var context = await listener.GetContextAsync(); if (context.Request.Url.AbsolutePath.Equals(""/basic"")) { var authHeader = context.Request.Headers[""Authorization""]; if (!string.IsNullOrEmpty(authHeader) && authHeader.StartsWith(""Basic "")) { // Authenticated, redirect. context.Response.Redirect(""/other""); } else { // Not authenticated context.Response.StatusCode = 401; context.Response.Headers[HttpResponseHeader.WwwAuthenticate] = ""Basic""; } } else if (context.Request.Url.AbsolutePath.Equals(""/other"")) { var authHeader = context.Request.Headers[""Authorization""]; var bytes = Encoding.UTF8.GetBytes($""Auth header after redirect: {authHeader}""); await context.Response.OutputStream.WriteAsync(bytes, 0, bytes.Length); } else { context.Response.StatusCode = 404; } context.Response.Close(); } } } } ``` Note this repro will break differently on .NET Framework where HttpListener is more restrictive about what headers you can set." 24844 area-System.Net Increase tolerance on SendTimesOut_Throws Fixes https://github.com/dotnet/corefx/issues/24804 (assuming it's just because the machine is slow) 24846 area-System.Net Add `Memory` support to WebSockets This is split into several commits as there are multiple related but distinct changes: 1. First, I moved ManagedWebSocket from being based on `ArraySegment` internally to being based on `Memory` internally. That then allows it to be used with either `ArraySegment` or `Memory`, as the former is convertible to the latter. 2. Then I added the new `CreateFromStream` method to WebSocket; this requires the `Memory` support in ManagedWebSocket because `CreateFromStream`'s scratch buffer is a `Memory`. 3. Then I used that new `CreateFromStream` method in both System.Net.WebSockets.Client and System.Net.HttpListener; ManagedWebSocket.cs now is only built into System.Net.WebSockets rather than into all three assemblies. 4. Then I added the new `Memory`-based Send/ReceiveAsync virtuals to WebSocket. 5. Then I overrode these on ManagedWebSocket, providing decent implementations for them. 6. And finally I overrode the `Memory`-based `ReceiveAsync` on WinHttpWebSocket. I didn't bother with `SendAsync` for now as the base implementation should be reasonable for common cases, and if we want to optimize this implementation, there are other things that can and should be done, too. cc: @geoffkizer, @davidsh, @anurse, @benaadams, @Priya91 Fixes https://github.com/dotnet/corefx/issues/22610 Contributes to https://github.com/dotnet/corefx/issues/21537 (we still need to expose it through an OOB) 24847 area-Infrastructure .NET Framework 4.7.1 compatibility issue with reflection-only loading "Now that netstandard.dll is in the GAC, this can cause failures when attempting to use reflection-only loading.

This is one aspect of the new stack that warrants quite a bit of up-front scrutiny. There have already been design improvements here with the central queue vs the old queue-per-connection strategy, but the limits also need to be redesigned. I’m not aware of any consistent connection management behavior across stacks or good publicized algorithms. Interviewing the WinHttp team would be one starting point. The RFC has removed the old limit of two connections per host, it now says: https://tools.ietf.org/html/rfc7230#section-6.4 ""...this specification does not mandate a particular maximum number of connections but, instead, encourages clients to be conservative when opening multiple connections. ... Note that a server might reject traffic that it deems abusive or characteristic of a denial-of-service attack, such as an excessive number of open connections from a single client."" There is nothing conservative about the current allocation algorithm. MaxConnectionsPerServer defaults to int.MaxValue and there is no throttling on the rate at which new connections will be established. The old ServicePointManager.DefaultConnectionLimit started at 2 but also had no allocation throttle. A burst of requests will cause new connections to be established for every request up to the limit. This is likely more expensive and slower than queueing some of those requests to reuse existing connections as they become available. Customers regularly run into the DefaultConnectionLimit bottleneck and ask what the correct value should be. There is no good answer to this question, nor even an easy way for the user to work it out for a specific application. This implies that the limit concept and allocation strategy themselves are flawed. The new stack isn't much different in this respect except that the default is MaxValue. This will manifest as a series of less obvious problems like added latency per request when they create extra new connections, added memory and CPU usage creating and maintaining idle connections, more sporadic failures when a request gets assigned to an idle connection that has been dropped, etc.. So what would a new design look like? It would need avoid being an app bottleneck like DefaultConnectionLimit, and also throttle bursts to avoid wasting resources like MaxConnectionsPerServer. The .NET thread pool has these mechanics and would be an interesting design to test. Threads are analogous to connections except that connections are even more expensive to create and maintain. Work items are analogous to requests though requests can be assigned to connections a lot longer. The thread pool injects new threads at a throttled rate and only slowly approaches its configurable limit. Similarly the connection pool should explore only injecting new connections at a throttled rate to prevent bursts from wasting resources. The thread pool also has a configurable min thread limit to avoid bottlenecks at startup." 24852 area-System.Diagnostics Support System.Diagnostics.Eventing on Linux/Mac Port `System.Diagnostics.Eventing` to Linux & Mac -- for Windows Event Log parsing purposes. I created a [SO post here](https://stackoverflow.com/questions/46915998/eventing-namespace-does-not-exist-in-system-diagnostics-in-net-core-and-mon) documenting the issue I currently have with `dotnet` and `mono`. 24853 area-System.Net ALPN No matching protocol tests fail On Windows they seem to hang and timeout On Linux they don't throw an exception but return an empty protocol 24854 area-System.Memory Provide IEnumerable support for Memory ## Rationale Users should be able to pass `Memory` to methods that take in `IEnumerable` similar to array. Currently, this requires calling ToArray() to copy the contents of the `Memory` into an array for it to work, and is unnecessary. For example (from @eerhardt): https://github.com/dotnet/corefxlab/blob/master/src/System.Numerics.Tensors/System/Numerics/DenseTensor.cs#L10 ```C# public void SomeMethod(DenseTensor tensor) { Memory memory = tensor.Buffer; var value = CreateBatch(..., memory.ToArray(), ...); } ``` https://github.com/Microsoft/CNTK/blob/master/bindings/csharp/CNTKLibraryManagedDll/ShimApiClasses/ValueShim.cs#L104 ```C# public static Value CreateBatch(NDShape sampleShape, IEnumerable batch, DeviceDescriptor device, bool readOnly = false) { T[] batchAsArray = batch.ToArray(); return CreateBatch(sampleShape, batchAsArray, 0, batchAsArray.Count(), device, readOnly); } ``` If `Memory` implemented `IEnumerable`, then the ToArray() call would not be required. However, this would cause applications that reference System.Memory and `Memory` for any scenario to be larger (when compiled AOT). Furthermore, if `Memory` was an `IEnumerable`, it might result in a pit of failure as it could lead to users unintentionally using the enumerator to iterate over the data rather than the more performant indexer on Memory.Span (especially for primitive types like `Memory`). To discourage unnecessary use of the enumerator but still provide support for the scenarios where you need an IEnumerable, the proposed solution is to add an adapter class and a ToEnumerable extension method on `Memory`. As an FYI, `Span` cannot implement `IEnumerable` since it is a stack-only, byref type, and casting it to an interface would cause boxing. The compiler will throw and error: `'Span': ref structs cannot implement interfaces` ## Proposed API ```C# namespace System { public static class MemoryExtensions { public static IEnumerable ToEnumerable(this Memory memory); } } ``` ## Usage Taking the above example, it would look as follows: ```C# public void SomeMethod(DenseTensor tensor) { Memory memory = tensor.Buffer; var value = CreateBatch(..., memory.ToEnumerable(), ...); } ``` ## Partial Implementation ```C# public static IEnumerable ToEnumerable(this Memory memory) => new MemoryEnumerable(memory); internal class MemoryEnumerable : IEnumerable { ReadOnlyMemory _memory; public MemoryEnumerable(ReadOnlyMemory memory) => _memory = memory; public IEnumerator GetEnumerator() => new MemoryEnumerator(_memory); IEnumerator IEnumerable.GetEnumerator() => new MemoryEnumerator(_memory); } internal class MemoryEnumerator : IEnumerator { ReadOnlyMemory _memory; int _index; public MemoryEnumerator(ReadOnlyMemory memory) => _memory = memory; public T Current => _memory.Span[_index]; object IEnumerator.Current => _memory.Span[_index]; public void Dispose() { throw new NotImplementedException(); } public bool MoveNext() { _index++; return _index <_memory.Length; } public void Reset() { _index = 0; } } ``` cc @eerhardt, @KrzysztofCwalina, @stephentoub, @jkotas, @terrajobst, @karelz, @ericstj 24855 area-System.ComponentModel CultureInfoConverter added CultureInfoConverter is added to list of IntrinsicTypeConvertersList to make deserialization of newtonsoft possible in .net core Fixes #24755 24856 area-Infrastructure Need to add Ubuntu 17.10 to the RID graph 24857 area-System.Net Implement cancellation token for SslStream new AuthenticateAs*Async methods also fixes #24853 cc @stephentoub @Tratcher @Drawaes 24861 area-System.Net Registered i/o We need interop delarations for RIO in the corefx repo 24862 area-System.Net WinHttpHandler is not using Host header in SSL handshake The .NET Framework does. 24863 area-System.Memory DO NOT MERGE, DO NOT REVIEW I only care what CI has to say at this time. 24865 area-Meta Memory problem My procedure is very simple, through the socket to accept the connection and then through the sslstream forward data to the back-end server, a simple socket proxy, but soon after the start of the system memory is exhausted, I guess there may be a memory leak, how should I find the problem The 24866 area-System.Net ALPN Failing Success on Debian All three tests SslStream_StreamToStream_Alpn_Success fail on Debian 90 24868 area-System.Net [release/2.0.0] Add locking to SecureTransport P/Invokes "Makes the macOS version of SslStream capable of doing one read and one write ""at the same time"" without taking down the process. release/2.0.0 port of #24833 Fixes #24821 Fixes #24142" 24869 area-System.Net IndexOutOfRangeException from Socket.MultipleAddressConnectAsyncResult.get_RemoteEndPoint https://mc.dot.net/#/user/Drawaes/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/3cac46b196961558ff0ddf1858e8a3429a7d643e/workItem/System.Net.Sockets.Tests/analysis/xunit/System.Net.Sockets.Tests.DnsEndPointTest~2FSocket_BeginConnectDnsEndPoint_Failure ``` Unhandled Exception of Type Xunit.Sdk.ThrowsException Message : Assert.Throws() Failure Expected: typeof(System.Net.Sockets.SocketException) Actual: typeof(System.IndexOutOfRangeException): Index was outside the bounds of the array.

I have also noticed that there was a recent change in the sync arguments that I have not discovered after rebase of my changes to master.

C# compiler certainly relies on the implied purity for the soundness of null-propagating math as well as in various optimizations. Basically - while for other structs `readonly` is a good thing to have, if possible. I think the spec for `Nullable` should _demand_ that `Nullable` is formally `readonly`. In particular we consider methods like `HasValue` not mutating and therefore callable directly on references to readonly fields (which is currently unverifiable). When verification rules are updated to understand readonly references, we would need to special case `Nullable` methods. - Unless the type is `readonly` by the spec, then the behavior would be subsumed by the general treatment or `readonly` structs. 24901 area-System.IO Check that long relative paths work on Windows We should check that long relative paths work on Windows. It appears (from looking at the source) that they do not. Problem is in [PathInternal.Windows.cs][1]: `EnsureExtendedPrefixOverMaxPath` simply returns if the path is relative, rather than calling `GetFullPathNameW` and then adding the extended prefix. As a result, the underlying Windows API function will fail. This is a rather simple fix, though I don’t have a Windows machine to test it with.

Without that we will end up selecting the netstandard asset and building and testing that when doing our netfx vertical testing. We can probably add a new property called something like IgnoreBuildConfigurations or InboxOnFramework and teach our configuration system (likely somewhere in https://github.com/dotnet/corefx/blob/master/buildvertical.targets#L70) to filter out and skip such configurations. 24904 area-System.Net Remove dead code from System.Net.Sockets PR addresses issue #17905, project **System.Net.Sockets**. 24907 area-System.IO Path.GetFullPath difference between Windows and Linux @YvonneArnoldus commented on [Thu Oct 26 2017](https://github.com/dotnet/coreclr/issues/14707) I have written some code that uses Path.GetFullPath().

"## Description While using `System.Xml.Serialization.XmlSerializer` with `XmlSerializer.Deserialize()` method, the output for an attribute which is supposed to be mapped to a List outputs empty values if there is only a whitespace character in the attribute, Is this the intended behaviour? ## Reproduction Steps 1) Create a .NET Core 2.0.2 console application. 2) Copy the following code to `Program.cs` file. ```c# using System; using System.Collections.Generic; using System.IO; using System.Xml; using System.Xml.Serialization; namespace XmlTest { internal class Program { private static void Main() { string xml = """"; List outputList = new List(); using (XmlReader reader = XmlReader.Create(new StringReader(xml))) { XmlSerializer serializer = new XmlSerializer(typeof(Test)); outputList = ((Test)serializer.Deserialize(reader)).List; } Console.WriteLine($""Input XML: {xml}""); Console.WriteLine($""Generated list's length: {outputList.Count}""); Console.WriteLine(""Listing the list contents:""); foreach (string output in outputList) { Console.WriteLine($""Content:'{output}', content length:{output.Length}""); } Console.WriteLine(""End of process. Press enter to exit...""); Console.ReadLine(); } } public class Test { [XmlAttribute(""list"")] public List List { get; set; } } } ``` 3) Run the code and read the console outputs. ## Observation The output seems like the result of code similar to the following: ```c# string test = "" ""; string[] parts = test.Split(' '); List output = new List(parts); ``` I couldn't find the spot where the serialization is happening in the code though, however if it's really something like this _and it is not the intended behaviour_, changing the `test.Split(' ')` piece to `test.Split(' ', StringSplitOptions.RemoveEmptyEntries)` should be fixing the issue." 24915 area-System.Runtime Update System.ObsoleteAttribute targets to include assembly ## Rationale Currently, `ObsoleteAttribute` can be used with types and members only which is very inconvenient when you need to obsolete the whole assembly.

I deleted `NamespaceManager.NamespaceBoundary` property because it is not used anywhere. But it sets `_nsTop` field.

First argument is 'async' or 'sync' for whether to call Accept() or AcceptAsync(). Second argument is 'shutdown' to try to stop listening socket by calling Shutdown(SocketShutdown.Both), then Dispose(), or 'dispose' to just call Dispose(). Third argument is 'signal' to register signal handlers for SIGINT (or ctrl+c on windows) and SIGTERM (netcore only), or 'auto' to automatically try to stop the listening socket after 3 seconds. Reproduction steps: On Linux, run ``` dotnet SocketStopTest.dll sync dispose auto ``` Expected result: A SocketException is thrown from the Accept() call and the program terminates. Actual result: The program hangs inside Socket.Dispose(). On Windows, both full framework and .net core, calling Dispose() on a Socket that is in a synchronous Accept() call will break it out of the Accept() call with a SocketException. On Linux, it hangs inside the Dispose(). On Linux, calling Shutdown(SocketShutdown.Both) before calling Dispose() works and causes a SocketException to be thrown from the Accept(), although the exception message is a little weird: ""Invalid argument"". But on Windows, whether full framework or .net core, calling Shutdown(SocketShutdown.Both) apparently hangs when called from regular code or throws a SocketException on the Shutdown (and does not interrupt the Accept) when called from a ctrl+c handler with a message of ""A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied"" With AcceptAsync(), Dispose() generally works as expected on Windows full framework, Windows .net core, and Linux .net core, with the small exception of Windows full framework raising ObjectDisposedException from the accept task instead of SocketException. See outcome.txt in the gist for outcomes of all combinations of Windows net47 vs Windows netcore vs Linux netcore, Accept() vs. AsyncAccept(), Shutdown(SocketShutdown.Both) + Dispose() vs. just Dispose(), and socket stopped from delayed Task vs. ctrl+c/SIGINT handler vs. SIGTERM handler. It's also far from clear from documentation what the correct way of interrupting an Accepting socket is. One might guess to call Dispose() on it, but calling Shutdown would be another reasonable guess and works on Linux but not Windows." 24945 area-System.Linq Remove private reflection agaist RuntimeWrappedException constructor RuntimeWrappedException constructor is public in CoreLib now.

But it seems impossible to use them with `System.Data.Odbc` available on MyGet since #13035, excepted `Date`. They look unsupported by this ODBC client, although I have the ""ODBC Driver 13 for SQL Server"" and its ""SQL Server Native Client 11.0"" driver: - Trying to read a `Time` column with a `System.Data.Odbc` reader `GetValue` yields: System.ArgumentException : Unknown SQL type - SS_TIME_EX. at System.Data.Odbc.TypeMap.FromSqlType(SQL_TYPE sqltype) at System.Data.Odbc.OdbcDataReader.GetSqlType(Int32 i) at System.Data.Odbc.OdbcDataReader.GetValue(Int32 i) - Trying to read a `Time` column with a `System.Data.Odbc` reader `GetTime` cuts fractional seconds. - Trying to set a `Time` parameter on an `OdbcCommand` cuts its fractional seconds. - Trying to set a `DateTime2` parameter on an `OdbcCommand` yields: System.ArgumentException : No mapping exists from DbType DateTime2 to a known OdbcType. at System.Data.Odbc.TypeMap.FromDbType(DbType dbType) at System.Data.Odbc.OdbcParameter.set_DbType(DbType value) - Setting a `DateTimeOffset` parameter yields the same error with just the db-type name accordingly changed. - Trying to read a `DateTimeOffset` column with a `System.Data.Odbc` reader `GetValue` yields: System.ArgumentException : Unknown SQL type - -155. at System.Data.Odbc.TypeMap.FromSqlType(SQL_TYPE sqltype) at System.Data.Odbc.OdbcDataReader.GetSqlType(Int32 i) at System.Data.Odbc.OdbcDataReader.GetValue(Int32 i) - Trying to read a `DateTimeOffset` column with a `System.Data.Odbc` reader `GetDateTime` cuts offset (but preserves fractional seconds (all 7 digits)). - Checking [`OdbcType`](https://github.com/dotnet/corefx/blob/master/src/System.Data.Odbc/src/System/Data/Odbc/OdbcType.cs) enumeration, it does not have types for `datetimeoffset` or `datetime2`. - Trying to dodge the trouble for `datetime2` by using `DbType.DateTime` instead for parameter: - Requires to set the parameter scale, otherwise fails with: System.Data.Odbc.OdbcException : ERROR [22008] [Microsoft][SQL Server Native Client 11.0]Datetime field overflow.

This gives the one millisecond precision (compared to SQL Server `datetime` ten thirds of ms precision), but `datetime2` can go down to 100ns. Catching the query with SQL Server Profiler, we can see this: exec sp_executesql N'select count(*) from Types2008 where [DateTime2] = @P1', N'@P1 datetime2','2017-10-26 20:01:55.1630000' So the value is `datetime2` typed but has its fractional milliseconds zeroed out (yes my original value was not having them already zeroed). By the way this `datetime2` typing causes issues when the underlying table column is `datetime` instead, because it occurs in this case too. It causes `where` equality conditions to fail matching on two thirds of `datetime` values. Those ending with `3` or `7` milliseconds are not considered equal to the ""same"" value when typed `datetime2` with four trailing zero. Only those ending with 0 millisecond match.

Some looks like design (inconsistency) issues, some may be code bugs. 1. **Possible design bug**: Inconsistent handling of `null` array members: This works as expected: ```C# var a = new JsonArray(new JsonValue[] { ""abc"", 123, null }); // Note 3rd item is null ``` This alternative pattern `throws` inside `Add` due to an explicit `null` guard: ```C# var b = new JsonArray(new JsonValue[] { ""abc"", 123 }); b.Add(null); // ArgumentNullException ``` I see that the units support this behavior, but it seems to be an inconsistent design. Adding a `null` member to an array should be acceptable? 2. **Possible code bug**: `JsonType` derivation on `JsonPrimitive` seems faulty: ```C# var p = new JsonPrimitive(Guid.NewGuid()); // Guid var t = p.JsonType; // Expected: JsonType.String. Actual: JsonType.Number ``` (The nested conditionals here may be iffy: [JsonPrimitive.cs](https://github.com/dotnet/corefx/blob/master/src/System.Json/src/System/Json/JsonPrimitive.cs#L118-L120)) This case does not seem to be covered by any units. ```C# public override JsonType JsonType => _value == null || _value.GetType() == typeof(char) || _value.GetType() == typeof(string) || _value.GetType() == typeof(DateTime) || _value.GetType() == typeof(object) ? JsonType.String // DateTimeOffset || Guid || TimeSpan || Uri // <========= : _value.GetType() == typeof(bool) ? JsonType.Boolean : JsonType.Number; ``` 3. **Possible design bug**: `JsonPrimitive.ToString()` throws for some primitives. The following throws; I would expect to return the `Guid` in `string` form. Note that this is _not_ one of the expected errors that are explicitly `thrown` for some types (see notes on stack trace). I see that the units support this behavior, but it seems to be an inconsistent design. ```C# var p = new JsonPrimitive(Guid.NewGuid()); var t = p.JsonType; var s = p.ToString(); // FormatException // Note that GetFormattedString explicitly throws for some types // But that's not happening here, since it's making it all the way to Guid.ToString() System.FormatException Message=Format String can be only ""D"", ""d"", ""N"", ""n"", ""P"", ""p"", ""B"", ""b"", ""X"" or ""x"". Source=System.Private.CoreLib StackTrace: at System.Guid.ToString(String format, IFormatProvider provider) at System.Json.JsonPrimitive.GetFormattedString() at System.Json.JsonValue.SaveInternal(TextWriter w) at System.Json.JsonValue.ToString() ``` 4. **Perf: Equals is Expensive**: The straight-forward way to compare two `JsonValue` instances is to `ToString()` them both and then use a `StringComparer.Ordinal` comparer. But this is unnecessarily expensive considering the number of `string` allocs that need to happen internally while walking the tree. A better way would be to walk the tree regardless, but compare each individual `JsonObject`, `JsonArray` and `JsonPrimitive`. Something similar to this: [JsonValueComparer.cs](https://github.com/k2workflow/Clay/blob/master/src/SourceCode.Clay.Json/JsonValueComparer.cs) [Benchmark](https://github.com/k2workflow/Clay/blob/master/src/SourceCode.Clay.Json.Bench/JsonEqualsBench.cs) (**2x improvement in both time & memory**) ```C# Method | Mean | Error | StdDev | Scaled | ScaledSD | Gen 0 | Gen 1 | Gen 2 | Allocated | ---------------- |----------:|----------:|----------:|-------:|---------:|---------:|---------:|--------:|----------:| ToStringEquals | 13.998 ms | 0.2782 ms | 0.5807 ms | 1.00 | 0.00 | 809.3750 | 434.3750 | 90.6250 | 6267600 B | NewtonDeepEquals | 2.729 ms | 0.0514 ms | 0.0456 ms | 0.20 | 0.01 | - | - | - | 0 B | SmartEquals | 6.817 ms | 0.1334 ms | 0.1638 ms | 0.49 | 0.02 | 789.0625 | - | - | 3323776 B | ``` 5. **Perf: Clone is Expensive**: Similar reasoning to the previous bullet: `ToString` works but is expensive due to allocations on the way out and redundant parsing on the way back in. Here's an alternative approach that walks the tree and clones each node explicitly: [JsonClone.cs](https://github.com/k2workflow/Clay/blob/master/src/SourceCode.Clay.Json/JsonExtensions.cs#L304-L430) (Unfortunately even it isn't as memory-efficient as it could be, since `SortedDictionary` does not expose an `initialCapacity` parameter in order to pre-allocate an exact-sized map.)

Seed is assumed to be zero as there is no ctor in the proposal - however, it is possible to add a seed without changing the structure. It's possible to do this without `unsafe`, but the code is much more messy. This can be changed if adding `AllowUnsafeBlocks` to System.Runtime is a problem. Tests against known xxHash32 vectors are provided. The hashes were calculated by providing chunks from `""abcd0123efgh4567ijkl8901mnop2345qrst6789uvwx0123yzab""` (increasing in length 4) to [this site](https://asecuritysite.com/encryption/xxHash). The integers are hard-coded in the tests because System.Text.Encoding.ASCII is not available. ## [Performance](https://github.com/jcdickinson/Benchmarks/tree/corefx-hashcode) ``` ini BenchmarkDotNet=v0.10.9, OS=Windows 10 Redstone 2 (10.0.15063) Processor=Intel Core i7-4800MQ CPU 2.70GHz (Haswell), ProcessorCount=8 Frequency=2630627 Hz, Resolution=380.1375 ns, Timer=TSC .NET Core SDK=2.0.2 [Host] : .NET Core 2.0.0 (Framework 4.6.00001.0), 64bit RyuJIT DefaultJob : .NET Core 2.0.0 (Framework 4.6.00001.0), 64bit RyuJIT ``` | Method | Mean | Error | StdDev | Scaled | |------------------------ |---------:|----------:|----------:|-------:| | Unsafe | 79.98 ns | 1.4723 ns | 1.3772 ns | 1.00 | | 'Calls, No Inlining' | 40.34 ns | 0.1778 ns | 0.1576 ns | 0.50 | | 'Unrolled, No Inlining' | 12.19 ns | 0.0433 ns | 0.0384 ns | 0.15 | | 'Calls, Inlining' | 34.55 ns | 0.1372 ns | 0.1216 ns | 0.43 | | 'Unrolled, Inlining' | 12.22 ns | 0.0885 ns | 0.0785 ns | 0.15 | ### Updates [(staged)](https://github.com/jcdickinson/corefx/tree/feature-system-hashcode-staged) The test vectors are now normally disabled due to the per-AppDomain seed randomization, define `SYSTEM_HASHCODE_TESTVECTORS` to enable them (which will disable the seed randomization, setting it to 0). NB: this has been excluded from netfx builds in the tests csproj. ## Deviations from xxHash32 * Length is stored as the number of hashed fields (not bytes). It is multiplied at the end by 4 so that it behaves exactly like xxHash32. * Due to the lazy state initialization (a necessity because HashCode is a struct), it is possible that the structure will re-initialize at field 4,294,967,300 (and multiples thereof) only if the xxHash32 state variables are somehow all zero. This could be deferred by changing the length field to a `ulong` (but would make the struct larger than a cache line). 4,294,967,300 fields ought to be enough for anyone; you have bigger problems if you are creating hash codes based on that much data (15GB). * The code that mixes in individual bytes is omitted - this struct only accepts `int`.

The provided prototype shows a micro-bench result of **2-3x** improvement. # Rationale and Usage There is no existing `Clone` method on `JsonValue`, but it's not an uncommon operation. The workaround is to roundtrip the value via `ToString` and `Parse`. But this is unnecessarily expensive considering the number of `string` allocs that need to happen on the way out and expensive, redundant parsing on the way back in. ```C# var json = new JsonObject(...); // Current idiom for cloning var str = JsonValue.ToString(); // Lots of string allocs var clone = (JsonObject)JsonValue.Parse(str); // Wasteful parsing // Proposed method var clone = (JsonObject)json.Clone(); ``` An alternatively approach is to migrate to `Newtonsoft.Linq.JValue` which has similar semantics, and though it's heavier in terms of memory (and api surface) it performs adequately. # Proposed API ```C# public class JsonValue : ICloneable // See open questions { // Existing interface unchanged // New method public JsonValue Clone(this JsonValue json) { ... } } ``` # Details This requires the introduction of a new `Clone` method on `JsonValue`, similar to this prototype: [JsonClone.cs](https://github.com/k2workflow/Clay/blob/master/src/SourceCode.Clay.Json/JsonExtensions.cs#L306-L444).

This proposal would permit the same idiom to be available for `Dictionary`. # Rationale and Usage This is a nice-to-have, but helps in environments where resources are constrained. The current idiom is to create a `new Dictionary(0)` but that incurs not-insignificant private state, and the semantics of 'immutably empty' are different to those for 'empty but not populated yet'. There are several data structures that build up maps of maps, for example `System.Json`. In scenarios where datasets are large, the cost and semantics of `pseudo-empty` add up. For scenarios where we have lists instead of maps, we already use `Array.Empty` or `Enumerable.Empty`. It would be consistent to provide the same facility for maps. ```C# var empty = Dictionary.Empty(); empty.Count; // 0 empty.IsReadOnly; // true empty[""hi""]; // KeyNotFound or InvalidOperation (?) empty.Add(...); // InvalidOperation Keys; // Array.Empty ``` # Proposed API ```C# public static class Dictionary // See open questions { /// /// Returns an empty dictionary that is immutable. /// /// The type of keys in the dictionary. /// The type of values in the dictionary. /// Returns an empty public static IDictionary Empty() => ; } public static class ReadOnlyDictionary { /// /// Returns an empty dictionary that is immutable. /// /// The type of keys in the dictionary. /// The type of values in the dictionary. /// Returns an empty public static IReadOnlyDictionary ReadOnlyEmpty() => ; } ``` # Details The singletons would return sensible defaults where possible for getters, though indexers would need to throw. Since `IsReadOnly==true`, mutators should throw too. All errors should align with those used when a traditional `Dictionary` has 'IsReadOnly=true`. # Open Questions * I am not sure what namespace & class name to use, since the chance of conflict (in user code) is high if we used `public static class Dictionary` to host the `Empty` singleton. Ditto for `ReadOnlyDictionary`. * I initially thought that the immutable nature of `Dictionary.Empty` might surprise or confuse users, but if we set `IsReadOnly=true` then it should cause less friction. `ReadOnlyDictionary.Empty` is already expected to be immutable, so it should not have the same problem. * Not sure exactly what errors to throw in the indexers and mutators.

However, it is not possible, as of now, to set the various keepalive options using a standard .NET API. Most platforms, more than simply allowing TCP keepalive, provide a subset of the following three options: * Keepalive Time * Keepalive Interval * Keepalive Retry Count Since Windows 2000, it has been possible to set both Keepalive Time and Keepalive Interval by using `SIO_KEEPALIVE_VALS` with Winsock IOCTL (Exposed via `Socket.IOControl` and `IOControlCode.KeepAliveValues` in .NET) Under Linux, TCP Keepalive can be configured with `setsockopt` under the `SOL_TCP` level. The allowed parameters are `TCP_KEEPCNT`, `TCP_KEEPIDLE` and `TCP_KEEPINTVL`. It seems OSX also has some good support for the feature since OSX Lion, only using slightly different names than Linux: https://lists.apple.com/archives/macnetworkprog/2012/Jul/msg00005.html From the docs, since Windows 10 version 1703 and 1709, settings that are code-compatible with Linux and OSX were introduced: https://msdn.microsoft.com/en-us/library/windows/desktop/ms738596(v=vs.85).aspx As explained in https://github.com/dotnet/corefx/issues/14237, it is impossible today to configure TCP keepalive on platforms other than Windows, where `Socket.IOControl` can do the trick. # Proposed API ```csharp enum SocketOptionName { //… #region SocketOptionLevel.Tcp //… // TCP KeepAlive options TcpKeepAliveRetryCount = 16, // TCP_KEEPCNT value from Ws2ipdef.h TcpKeepAliveTime = 3, // TCP_KEEPIDLE = TCP_KEEPALIVE value from Ws2ipdef.h TcpKeepAliveInterval = 17, // TCP_KEEPINTVL value from Ws2ipdef.h #endregion //… } ``` # Example ```csharp void EnableKeepAlive(Socket socket, byte retryCount, int keepAliveTimeInSeconds, int keepAliveIntervalInSeconds) { socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.KeepAlive, true); socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.TcpKeepAliveRetryCount, (int)retryCount); socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.TcpKeepAliveTime, keepAliveTimeInSeconds); socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.TcpKeepAliveInterval, keepAliveIntervalInSeconds); } ``` # Details The PAL for each supported platform would translate the call to `Socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.TcpKeepAlive*, *)` into the appropriate call for the platform. * On Linux, and OSX ≥ 10.7, .NET enumeration values would be translated to corresponding system values for `setsockopt()`. * On Windows 10 version 1709 and newer, the flags would be transferred as-is to the underlying Winsock API, as they already are today. * Ideally, `TcpKeepAliveTime` and `TcpKeepAliveInterval` would be marshalled to `socket.IOControl(IOControlCode.KeepAliveValues, KeepAliveValues, null)` for previous versions of windows, while `TcpKeepAliveRetryCount` would be simply ignored. ⚠️ Beware that commonly used socket option names `TCP_KEEPIDLE` (or `TCP_KEEPALIVE`) and `TCP_KEEPINTVL` are expressed in seconds, while `SIO_KEEPALIVE_VALS` expresses durations in milliseconds. # Questions The TCP keepalive feature being optional, it is not required that all platforms support it or provide any specific way of configuring the feature. * Should a call to a non supported TCP keepalive option throw an exception ? * How should a caller determine if a given option is indeed supported on the current platform ? * Should an additional socket property, similar to `Socket.LingerState` be also added (e.g. `KeepAliveState` of type `KeepAliveOption`), in order to group the various options and handle everything at one place ? * The feature could be used with something like `socket.KeepAliveState = new KeepAliveOption(true, 15, 7200, 1)` * This would also be more consistent with the way the feature is configured on legacy Windows system. 25041 area-Microsoft.CSharp Remove some redundances from Microsoft.CSharp * Remove dead path from `CheckAccessCore`. If `aggWhere` was null we return, otherwise last for must happen at least once. Within that if `atsThru` is null we return, therefore later path for `atsThru` being null cannot be hit. * Remove dead test from `TryReportLvalueFailure` If `!isNested` we are on the first loop so if `pObject != null` and `!(expr is ExprField)` then we know statically that `expr is ExprProperty` as only paths for it being `ExprField` or `ExprProperty` set `pObject`, so remove redundant test. * Remove parameter from `bindFloatOp` that is always overwritten. * Remove parameter from `LScalar` that is always overwritten. * Reduce duplication in `BindIncOpCore`. * Remove some unused assignments. 25042 area-Microsoft.CSharp MS.CSharp: Remove checks for locals as possible source of lvalue errors.

Secondly as `ExprLocal` have Flags set to `EXPRFLAG.EXF_LVALUE` and that flag never removed, the paths for `expr.isLvalue` within both `checkLvalue` and `TryReportLvalueFailure` (just before it loops) will mean an `ExprLocal` is never examined within `TryReportLvalueFailure`, and so `ReportLocalError` can never be called.

(Though I haven't been able to reproduce this.) On Unix, it's passed onto `ProcessWaitState.WaitForExit(int)`: https://github.com/dotnet/corefx/blob/1fc008a7e174345826e658672b74aa449fb3573f/src/System.Diagnostics.Process/src/System/Diagnostics/Process.Unix.cs#L120-L122 Which then has a special case for -1 (`Timeout.Infinite`), but not other negative values: https://github.com/dotnet/corefx/blob/1fc008a7e174345826e658672b74aa449fb3573f/src/System.Diagnostics.Process/src/System/Diagnostics/ProcessWaitState.Unix.cs#L362-L379 As far as I can tell, this means that on Unix `process.WaitForExit(-2)` behaves effectively the same as `process.WaitForExit(0)`: it doesn't wait at all, it just returns whether the process already exited. The options I can see are: 1. Do nothing. 2. Validate the input only on Windows. This would fix the `ParamName` on Windows, and wouldn't cause a breaking change on Unix. But it would mean Windows and Unix are going to stay inconsistent. 3. Always validate the input. This would fix the `ParamName` on Windows and it would mean the behavior on Unix would be deliberate, not accidental. But it would also be a breaking change: code that didn't throw before would start throwing. What do you think is the best approach here?

The immediate problem is it hitting a path that assumes it is dealing with an `AggregateType` when it is dealing with a `NullableType`, but it seems a bit more than just a spot fix there will be needed to make it handle the combination of both lifting and between enumerable types and their underlying types. Code using `dynamic` will likely never hit this as nullable types will never be inferred from a single `dynamic` argument, but it'd be safer to have this work correctly, as well as it ideally being workable for explicit use as in the example above. 25069 area-System.Diagnostics Test failure: System.Diagnostics.Tests.EventLogEntryCollectionTests/CheckingEntryEqualityAndIndex Opened on behalf of @Sunny-pu The test `System.Diagnostics.Tests.EventLogEntryCollectionTests/CheckingEntryEqualityAndIndex` has failed.

I was about to open an issue over there but then read a closed issue where they recommended opening new issues over here instead. In the current reference source it appears that there is needless looping over the entire enumerable even if the count of elements that match the predicate is greater than one. Here's a quick one-liner example of a short-circuit exit improvement (notice the added line right after `checked { count++; }`), although I'm sure it could be improved even further: public static TSource SingleOrDefault(this IEnumerable source, Func predicate) { if (source == null) throw Error.ArgumentNull(""source""); if (predicate == null) throw Error.ArgumentNull(""predicate""); TSource result = default(TSource); long count = 0; foreach (TSource element in source) { if (predicate(element)) { result = element; checked { count++; } if (count == 2) { break; } } } switch (count) { case 0: return default(TSource); case 1: return result; } throw Error.MoreThanOneMatch(); } Let me know if this is the appropriate place for this issue. It could also be that the reference source doesn't reflect exactly what the implementation is doing, because I would expect something like the Enumerable methods would have long-since been hand-tuned for performance. --- @benaadams commented on [Sun Nov 05 2017](https://github.com/dotnet/core/issues/1061#issuecomment-342066802) It seems to be fixed in corefx? https://github.com/dotnet/corefx/blob/master/src/System.Linq/src/System/Linq/Single.cs However, for a performance improvement, you should be able to just open and Issue in the repository that has the source or open a PR change.

We should now also share tests in order to minimize functional differences. In CoreFX we have a attempted to separate out tests for .NET Standard. In discussion with @marek-safar and @luhenry of Xamarin it likely makes sense to make this test bed reuseable so we can run it against Xamarin as well. We expect this to also help us drive standardization/documentation of the behavior of .NET Standard API's, where it's not already clear. We’d like to establish principles (with examples) for which behavior we’d like to prescribe. There is inherent tension between making .NET behavior consistent across all platforms and making .NET behavior self-consistent on a given platform. Sharing tests will help map this out, and prevent divergence.

We should fix that so that `ReadOnlyMemory` can be used as a way to slice strings where the slices can live on the heap. To me that means: 1. Allowing `ReadOnlyMemory` to wrap a `string` in addition to wrapping a `T[]` and an `OwnedMemory`. This will mean an extra type check on operations like `ReadOnlyMemory.Span`, but it can be guarded behind a `typeof(T) == typeof(char)` check such that the additional branch and few additional instructions will only impact `T==char`, and `string` will end up being a very common case for `T==char`, making it worth it. 2. Adding an `AsReadOnlyMemory()` extension method for`string` just as there's an `AsReadOnlySpan()` extension. 3. Adding a `TryGetString` method on `MemoryMarshal` or some similar place that enables getting the string/offset/count out of a `ReadOnlyMemory` if it's wrapping one. 4.

To achieve that, one currently has to first get the UTC time, then get a specific time zone (if one doesn't have it already), and then convert the time to that time zone. This proposal is to add an API to make that one step instead of two or three. ## Proposed API ```diff namespace System { public class TimeZoneInfo { + public DateTimeOffset Now { get; } } } ``` ## Example Usage ```csharp DateTimeOffset now = TimeZoneInfo.FindSystemTimeZoneById(""Eastern Standard Time"").Now; ``` Note that the above has been edited based on the conversation in this thread.

Unfortunately we lead users to the pit of failure because `mystring.Contains(char)` will bind to the Linq version, which can easily be 20x slower than `mystring.IndexOf(char) != -1`. By adding these to string, the next recompile will give a performance improvement. ## Proposed API ```c# public sealed partial class String : System.Collections.Generic.IEnumerable, System.Collections.IEnumerable, System.IComparable, System.IComparable, System.IConvertible, System.IEquatable, System.ICloneable { public bool Contains(char value) { throw null; } public bool Contains(char value, StringComparison comparisonType) { throw null; } public bool Contains(string value) { throw null; } // already exists public bool Contains(string value, StringComparison comparisonType) { throw null; } // already exists public int IndexOf(char value, StringComparison comparisonType) { throw null; } // to implement above } ``` the implementations will simply be ```c# public bool Contains(char value) { return IndexOf(value) != -1; } public bool Contains(char value, StringComparison comparisonType) { return IndexOf(value, comparisonType) != -1; } ``` ## Microbenchmark Searching in 10 and 1000 character strings: ``` Method | Mean | Error | StdDev | ---------- |-----------:|----------:|----------:| LinqShort | 142.750 ns | 0.4997 ns | 0.4430 ns | LinqLong | 180.121 ns | 0.4741 ns | 0.3428 ns | FastShort | 7.575 ns | 0.0196 ns | 0.0174 ns | FastLong | 8.508 ns | 0.0403 ns | 0.0377 ns | ``` ## Variations The StringComparison overload is in order to search case insensitively if desired. The IndexOf overload is needed to implement it.

For example, the US went through a DST transition recently. Using methods such as `AddDays` and similar do not reflect that correctly - even on the `DateTimeOffset` versions. I suggest adding the following: ## Proposed API ```diff namespace System { public struct DateTimeOffset { + public static DateTimeOffset AddYears(int years, TimeZoneInfo timeZone) + public static DateTimeOffset AddMonths(int months, TimeZoneInfo timeZone) + public static DateTimeOffset AddDays(int days, TimeZoneInfo timeZone) + public static DateTimeOffset AddHours(double hours, TimeZoneInfo timeZone) + public static DateTimeOffset AddMinutes(double minutes, TimeZoneInfo timeZone) + public static DateTimeOffset AddSeconds(double seconds, TimeZoneInfo timeZone) + public static DateTimeOffset AddMilliseconds(double milliseconds, TimeZoneInfo timeZone) + public static DateTimeOffset AddTicks(long ticks, TimeZoneInfo timeZone) + public static DateTimeOffset Add(TimeSpan timeSpan, TimeZoneInfo timeZone) + public static DateTimeOffset Subtract(TimeSpan timeSpan, TimeZoneInfo timeZone) } public struct DateTime { + public static DateTime AddYears(int years, TimeZoneInfo timeZone) + public static DateTime AddMonths(int months, TimeZoneInfo timeZone) + public static DateTime AddDays(int days, TimeZoneInfo timeZone) + public static DateTime AddHours(double hours, TimeZoneInfo timeZone) + public static DateTime AddMinutes(double minutes, TimeZoneInfo timeZone) + public static DateTime AddSeconds(double seconds, TimeZoneInfo timeZone) + public static DateTime AddMilliseconds(double milliseconds, TimeZoneInfo timeZone) + public static DateTime AddTicks(long ticks, TimeZoneInfo timeZone) + public static DateTime Add(TimeSpan timeSpan, TimeZoneInfo timeZone) + public static DateTime Subtract(TimeSpan timeSpan, TimeZoneInfo timeZone) } } ``` ## Example Usage ```csharp // setup TimeZoneInfo tz = TimeZoneInfo.FindSystemTimeZoneById(""Eastern Standard Time""); DateTimeOffset dto = DateTimeOffset.Parse(""2017-11-05T00:00:00-04:00""); // example of using AddDays in existing API DateTimeOffset result1 = dto.AddDays(1); // 2017-11-06T00:00:00-04:00 // example of using AddDays with respect to time zone in proposed API DateTimeOffset result2 = dto.AddDays(1, tz); // 2017-11-06T00:00:00-05:00 // example of using AddHours in existing API DateTimeOffset result3 = dto.AddHours(24); // 2017-11-06T00:00:00-04:00 // example of using AddHours with respect to time zone in proposed API DateTimeOffset result4 = dto.AddHours(24, tz); // 2017-11-05T23:00:00-05:00 ``` Note that in this context, `AddDays` is intended to manipulate a calendar day, not an elapsed 24-hour duration. Thus its argument is an `int` rather than a `double`. `AddMonths` and `AddYears` already behave similarly. Also, if #24555 goes through, then we'd also need `AddMicroseconds` versions of the above. For discussion: We could also include overloads that allow the user to supply a delegate to control how ambiguous results are handled, and how invalid or ambiguous `DateTime` inputs are resolved. Or we could default that behavior to existing behaviors present in the framework already, or to something more sensible for these scenarios.

Navigate to the attribute `xmlns:x` using `XmlReader.MoveToAttribute` API. The `XmlReader` properties `Name`, `Prefix`, `LocalName` respectively return `xmlns:x`, `xmlns` and `x`, which is correct. While the reader is positioned at the attribute, call `ReadAttributeValue`. Now, the `XmlReader` respectively returns values `xmlns:`, `xmlns` and `` for the same attribute, This doesn't appear to be intuitive. Looks like this is because the `reader` is internally positioned at the attribute value node which is of type text and hence the `LocalName` property returns `` as per the definition of the property. However, the end user would typically expect same values for `Name`, `Prefix` and 'LocalName` properties as from the user point of view, the reader is really not positioned at the ""text node"" that represents the _value of the attribute_.

It's configured in the code to request a client certificate. Kestrel is configured with a CA issued server certificate and exposes port 443. Testing 1. A client application written in .NET 4.5-6 uses a self-signed client certificate (using makecert) 2. A client application written in .NET Core 1.1 and 2.0 uses the same self-signed client certificate (using makecert). In a case of .NET 4.5X, the code seems to verify the list of cert issuers from the server against the client certificate it's trying to send. It finds no matching CA and fails to send the cert to the server and closes the connection as expected by TLS spec. In a case of .NET Core, the code seems to not perform the same comparison and just sends the client cert to the server and allows the connection to remain open.

It creates an Xml serialization assembly for types contained in an assembly in order to improve the startup performance of Xml serialization when serializing or de-serializing objects of those types using XmlSerializer. You can start using the tool today by following the [instructions](https://github.com/dotnet/core/blob/master/samples/xmlserializergenerator-instructions.md). ## Details When the Xml Serializer Generator is not used, an XmlSerializer generates serialization code for each type every time when an application runs. You can improve the startup performance of Xml serialization by simply adding the reference of Microsoft.XmlSerializer.Generator NuGet package to your project. Xml Serializer Generator will generate the serialization code and compile it into an assembly next to your output assembly at build time in advance. This assembly can then be deployed and ran with your application. Please create an issue with your feedback at [dotnet/corefx](https://github.com/dotnet/corefx/issues). We are actively looking to improve the tool and your input is a valuable part of the process. 25142 area-System.Data Add UDT support to System.Data.SqlClient. 25144 area-System.Threading Fix some tests after https://github.com/dotnet/coreclr/pull/14864 Fix for some test failures in https://github.com/dotnet/corefx/pull/25131 25145 area-Infrastructure Question: How do we do performance test? I had a small conversation with @karelz on the Gitter Coreclr channel. Here is the chat transcript Hi, Just wondering how the performance test is done for the core clr Karel Zikmund @karelz Nov 08 23:05 We have a perf lab with perf test cases. The perf lab and its results is internal only at this moment. What exactly are you interested in? @karelz I am more interested in how it’s done. What OS? And what parameters we are monitoring?. Knowing OS is important because in my office we have guy coming from a well know anti virus software company and he said that his company has profiled that Windows 7 is much better than Windows 10 for doing perf tests and it's stats because windows 10 has lot of background services running which hinders the stats. Its hard to believe for me. So thought of knowing how your team does and what's the rational Karel Zikmund @karelz 06:46 @sherry-ummen our perf lab removes all noise from machines - disables all kind of background services and OS features (PreFetcher, etc.), which could interfere with our measurements and introduce noise. Key thing for performance is to focus on things which matter and remove noise/variance of the environment. For micro-benchmarks we measure time and memory. .NET Core perf tests use xunit-performance harness (see Microsoft/xunit-performance) and we are discussing merging it with BenchmarkDotNet. However, it does not contain all the perf lab scripts to set up the machines, etc. Sherry Ummen @sherry-ummen 06:52 So then I assume you are using windows OS for perf test? Which OS? And do you have some scripts to disable all the background noise? Any plans to share those? Karel Zikmund @karelz 08:55 We run perf on Linux and Mac as well. Windows is just something we run for 10+ years ...I am not sure if the infra scripts are open or not (I know that few years ago the perf test harness was way too involved to be open-sourced). It would be best to ask on GH - I can loop in perf team if you tag me (I haven't been involved in perf team work for last 2 years) Sherry Ummen @sherry-ummen 09:07 I assume GH means Github? And which Repo in Github I should ask? Coreclr Repo? Karel Zikmund @karelz 09:11 coreclr or corefx will both work fine ------------------------------------------------------ So in short I am interested in the said infra scripts which are used to setup a machine. In my case a Windows machine. Whether its open sourced if not then any plans to open source it? 25148 area-System.Reflection IndexOutOfRangeExceptions on multiple System.Reflection.Metadata tests in CI on macOS

As described in #15033, this is not true in actual practice. Especially because `NetworkStream.ReadAsync()` ignores the `CancellationToken` altogether. Thus, I think the documentation for `Stream.ReadAsync()` should be changed to indicate that the parameter is advisory. For code accepting a `Stream`, there is no way (without reflection which should not be required of consumers—and, even with reflection, one may be consuming a stream which wraps `NetworkStream`) to tell if the `CancellationToken` will be ignored or not. So such code always needs to be written in such a way as to support streams with uncancellable read (and write?) operations. 25157 area-System.Diagnostics System.DllNotFoundException: Unable to load DLL 'libproc': "_From @livarcocc on October 6, 2017 16:16_ _From @Petermarcu on October 6, 2017 16:3_ @m2b commented on [Thu Apr 20 2017](https://github.com/dotnet/core/issues/599) **Here is the simple test project code** using System; using Xunit; namespace ITVizion.ActionBoard.RepositoryInMemory { public class Test { [Fact] public void Test1() { Assert.Equal(1,1); } } } ========================================================================= **Here is the command window output. dotnet crashes!** blackielanetMBP:actionboard.git blackie$ dotnet test ITVizion.ActionBoard.RepositoryInMemory.Test/ITVizion.ActionBoard.RepositoryInMemory.Test.csproj Welcome to .NET Core! --------------------- Learn more about .NET Core @ https://aka.ms/dotnet-docs.

Any chance you can share more about which version of everything you are running and how you installed it? Through the installer or from the tar.gz? --- @Petermarcu commented on [Wed Jun 28 2017](https://github.com/dotnet/core/issues/599#issuecomment-311856464) I'm going to close this because we need more info. Please reopen if you have more info you can share. Thanks! --- @jpcarrascal commented on [Sun Jul 09 2017](https://github.com/dotnet/core/issues/599#issuecomment-313953236) I have exactly the same problem. I am running OS X El Capitan (10.11.6). dotnet --version output is 1.0.4. I tried both the installer and running the binary from the tar.gz and the result is the same. The only difference is that in the former case I also get a ""dotnet quit unexpectedly"" window. I'd appreciate any help and I'll be happy to provide more diagnostics information if needed. Thanks!

Right now im using reflection to get that Info but i wonder why you make that an internal. (the info is there via debugview but neither toString or any public api can be used to get that information) im using that information to determine performance bottlenecks in my app. I know that consumers of buffers with growing fill level have to be optimized. _Copied from original issue: dotnet/corefxlab#1782_ 25163 area-System.Net [ManagedHandler] Do not change the request object provided by the user It is general implementation policy in other handlers in System.Net.Http, to not modify the HttpRequestMessage object provided by the user through the SendAsync method.

The constructor does not try to check whether the given collection is another `Stack`. The constructor just enumerates the source stack (in the `Pop()` order) and pushes all values in the new stack. The result is that the new stack is actually reversed.

"We have a number of **existing** indexable types that could benefit from a ref-returning element accessor. For example `ImmutableArray`. A typical problem is that such types already have a get/set indexer, so the only way to add an indexed byref access to elements is to add a ref returning method. I believe this will happen one way or another, since there is a motivation. So, I think we should standardize on the name of such method. Here I want to propose the following convention: ```C# // when container is readonly - I.E. ImmutableArray public ref readonly T ItemRef(int index); // when container is writeable - I.E. List public ref T ItemRef(int index); ``` The alternatives could be - “ElementAt” – often already taken - “Item” – clashes with the underlying name of the indexer - “Address” - could work too, but I think “ItemRef” reads a lot better. - “ItemAt” – original proposed name, ""ItemRef"" still seems better Examples of uses: ```C# public class Program { static void Main(string[] args) { var o = new MyCollection(); // use for assignment o.ItemRef(1) = 42; // bind to a ref local ref var first = ref o.ItemRef(1); first = 42; // read indirectly. (assume the API takes ""in"" parameter) Print(o.ItemRef(1)); } } class MyCollection { public ref T ItemRef(int index) => throw null; } ``` Once we agree on the name/pattern we can enter separate bugs for particular APIs. " 25190 area-Microsoft.CSharp Microsoft.CSharp should allow operations on identically-named types "In the rare case that two types have exactly the same type name, dynamic operations will fail: ```C# dynamic x = Activator.CreateInstance( AssemblyBuilder .DefineDynamicAssembly(new AssemblyName(""TestAssembly""), AssemblyBuilderAccess.Run) .DefineDynamicModule(""TestModule"") .DefineType(""TestType"", TypeAttributes.Public) .CreateType()); dynamic y = Activator.CreateInstance( AssemblyBuilder .DefineDynamicAssembly(new AssemblyName(""TestAssembly""), AssemblyBuilderAccess.Run) .DefineDynamicModule(""TestModule"") .DefineType(""TestType"", TypeAttributes.Public) .CreateType()); x.Equals(y); // This or any other operation with both objects fails. ``` #23021 changed the exception thrown in this case from `RuntimeBinderInternalCompilerException` to `RuntimeBinderException`; pretty much a change from ""sorry, we got this wrong"" to ""sorry, you can't do that"". Ideally such cases should succeed. While the case is extremely rare: 1. It's always better to allow users to do something that prohibit. 2. By the very nature of dynamic binding, there's no theoretical justification for disallowing it. 3. Handling the exception requires resetting a lot of state. Allowing this reset means a lot of objects being passed around so that the type manager, symbol manager, etc. can be accessed by those objects that need them, tying those objects to each other, in order to deal with this rare case. While the first two points relate to what is an obscure edge case, the third is a greater motivation for allowing this IMO.

Fixes #25190 * Remove `ResetBindException` No longer used. * Cache types' arity for `FindSymWithMatchingArity` instead of on each loop * Move byref handling out of `LoadSymbolsFromType()` Only one caller can possibly pass byref types, so handle it there. * Further simplify type matching. Since we're looking to match types, and types with different arity don't match, just look for the type itself. * Remove dead code and tidy up. Paths within the case of the type `.IsNullableType()` handle the possibility of the type itself being `Nullable`, but that type returns false for the nullable type check (possibly not true in the static compiler?). Remove the branches for that, and tidy up. * Move handling of nullable types. Since there can be corresponding `AggregateSymbol`s we have to test for it anyway, so may as well test before any more work is done. * Use `InsertRange` instead of repeated inserts.

As you can see, it's limited only to `int` values. ```csharp public readonly struct Range { public readonly long Index; public readonly long Length; } public readonly ref struct Span { public Span Slice(Range range) => Slice(range.Index, range.Length); public Span Slice(int index, int length) { throw null; } } ``` ```csharp var buffer = new Span(); var slice1 = buffer[3..4]; // with syntax sugar var slice2 = buffer.Slice(new Range(3, 4 - 3)); // without it ``` So it would be nice to have a generic one instead it to represent ranges of different types. ## Rationale and Usage Implementing the generic version would allow to have a common type to represent ranges. There are too many areas where it could be used including numeric processing, range based operations, and simply to store intervals (for example `Range
