v7.1.0 ====== Features -------- - Improve import time (python/cpython#114664). Bugfixes -------- - Make MetadataPathFinder.find_distributions a classmethod for consistency with CPython. Closes #484. (#484) - Allow ``MetadataPathFinder.invalidate_caches`` to be called as a classmethod. v7.0.2 ====== No significant changes. v7.0.1 ====== Bugfixes -------- - Corrected the interface for SimplePath to encompass the expectations of locate_file and PackagePath. - Fixed type annotations to allow strings. v7.0.0 ====== Deprecations and Removals ------------------------- - Removed EntryPoint access by numeric index (tuple behavior). v6.11.0 ======= Features -------- - Added ``Distribution.origin`` supplying the ``direct_url.json`` in a ``SimpleNamespace``. (#404) v6.10.0 ======= Features -------- - Added diagnose script. (#461) v6.9.0 ====== Features -------- - Added EntryPoints.__repr__ (#473) v6.8.0 ====== Features -------- - Require Python 3.8 or later. v6.7.0 ====== * #453: When inferring top-level names that are importable for distributions in ``package_distributions``, now symlinks to other directories are honored. v6.6.0 ====== * #449: Expanded type annotations. v6.5.1 ====== * python/cpython#103661: Removed excess error suppression in ``_read_files_egginfo_installed`` and fixed path handling on Windows. v6.5.0 ====== * #422: Removed ABC metaclass from ``Distribution`` and instead deprecated construction of ``Distribution`` objects without concrete methods. v6.4.1 ====== * Updated docs with tweaks from upstream CPython. v6.4.0 ====== * Consolidated some behaviors in tests around ``_path``. * Added type annotation for ``Distribution.read_text``. v6.3.0 ====== * #115: Support ``installed-files.txt`` for ``Distribution.files`` when present. v6.2.1 ====== * #442: Fixed issue introduced in v6.1.0 where non-importable names (metadata dirs) began appearing in ``packages_distributions``. v6.2.0 ====== * #384: ``PackageMetadata`` now stipulates an additional ``get`` method allowing for easy querying of metadata keys that may not be present. v6.1.0 ====== * #428: ``packages_distributions`` now honors packages and modules with Python modules that not ``.py`` sources (e.g. ``.pyc``, ``.so``). v6.0.1 ====== * #434: Expand protocol for ``PackageMetadata.get_all`` to match the upstream implementation of ``email.message.Message.get_all`` in python/typeshed#9620. v6.0.0 ====== * #419: Declared ``Distribution`` as an abstract class, enforcing definition of abstract methods in instantiated subclasses. It's no longer possible to instantiate a ``Distribution`` or any subclasses unless they define the abstract methods. Please comment in the issue if this change breaks any projects. This change will likely be rolled back if it causes significant disruption. v5.2.0 ====== * #371: Deprecated expectation that ``PackageMetadata.__getitem__`` will return ``None`` for missing keys. In the future, it will raise a ``KeyError``. v5.1.0 ====== * #415: Instrument ``SimplePath`` with generic support. v5.0.0 ====== * #97, #284, #300: Removed compatibility shims for deprecated entry point interfaces. v4.13.0 ======= * #396: Added compatibility for ``PathDistributions`` originating from Python 3.8 and 3.9. v4.12.0 ======= * py-93259: Now raise ``ValueError`` when ``None`` or an empty string are passed to ``Distribution.from_name`` (and other callers). v4.11.4 ======= * #379: In ``PathDistribution._name_from_stem``, avoid including parts of the extension in the result. * #381: In ``PathDistribution._normalized_name``, ensure names loaded from the stem of the filename are also normalized, ensuring duplicate entry points by packages varying only by non-normalized name are hidden. Note (#459): This change had a backward-incompatible effect for any installers that created metadata in the filesystem with dashes in the package names (not replaced by underscores). v4.11.3 ======= * #372: Removed cast of path items in FastPath, not needed. v4.11.2 ======= * #369: Fixed bug where ``EntryPoint.extras`` was returning match objects and not the extras strings. v4.11.1 ======= * #367: In ``Distribution.requires`` for egg-info, if ``requires.txt`` is empty, return an empty list. v4.11.0 ======= * bpo-46246: Added ``__slots__`` to ``EntryPoints``. v4.10.2 ======= * #365 and bpo-46546: Avoid leaking ``method_name`` in ``DeprecatedList``. v4.10.1 ======= v2.1.3 ======= * #361: Avoid potential REDoS in ``EntryPoint.pattern``. v4.10.0 ======= * #354: Removed ``Distribution._local`` factory. This functionality was created as a demonstration of the possible implementation. Now, the `pep517 `_ package provides this functionality directly through `pep517.meta.load `_. v4.9.0 ====== * Require Python 3.7 or later. v4.8.3 ====== * #357: Fixed requirement generation from egg-info when a URL requirement is given. v4.8.2 ====== v2.1.2 ====== * #353: Fixed discovery of distributions when path is empty. v4.8.1 ====== * #348: Restored support for ``EntryPoint`` access by item, deprecating support in the process. Users are advised to use direct member access instead of item-based access:: - ep[0] -> ep.name - ep[1] -> ep.value - ep[2] -> ep.group - ep[:] -> ep.name, ep.value, ep.group v4.8.0 ====== * #337: Rewrote ``EntryPoint`` as a simple class, still immutable and still with the attributes, but without any expectation for ``namedtuple`` functionality such as ``_asdict``. v4.7.1 ====== * #344: Fixed regression in ``packages_distributions`` when neither top-level.txt nor a files manifest is present. v4.7.0 ====== * #330: In ``packages_distributions``, now infer top-level names from ``.files()`` when a ``top-level.txt`` (Setuptools-specific metadata) is not present. v4.6.4 ====== * #334: Correct ``SimplePath`` protocol to match ``pathlib`` protocol for ``__truediv__``. v4.6.3 ====== * Moved workaround for #327 to ``_compat`` module. v4.6.2 ====== * bpo-44784: Avoid errors in test suite when DeprecationWarnings are treated as errors. v4.6.1 ====== * #327: Deprecation warnings now honor call stack variance on PyPy. v4.6.0 ====== * #326: Performance tests now rely on `pytest-perf `_. To disable these tests, which require network access and a git checkout, pass ``-p no:perf`` to pytest. v4.5.0 ====== * #319: Remove ``SelectableGroups`` deprecation exception for flake8. v4.4.0 ====== * #300: Restore compatibility in the result from ``Distribution.entry_points`` (``EntryPoints``) to honor expectations in older implementations and issuing deprecation warnings for these cases: - ``EntryPoints`` objects are once again mutable, allowing for ``sort()`` and other list-based mutation operations. Avoid deprecation warnings by casting to a mutable sequence (e.g. ``list(dist.entry_points).sort()``). - ``EntryPoints`` results once again allow for access by index. To avoid deprecation warnings, cast the result to a Sequence first (e.g. ``tuple(dist.entry_points)[0]``). v4.3.1 ====== * #320: Fix issue where normalized name for eggs was incorrectly solicited, leading to metadata being unavailable for eggs. v4.3.0 ====== * #317: De-duplication of distributions no longer requires loading the full metadata for ``PathDistribution`` objects, entry point loading performance by ~10x. v4.2.0 ====== * Prefer f-strings to ``.format`` calls. v4.1.0 ====== * #312: Add support for metadata 2.2 (``Dynamic`` field). * #315: Add ``SimplePath`` protocol for interface clarity in ``PathDistribution``. v4.0.1 ====== * #306: Clearer guidance about compatibility in readme. v4.0.0 ====== * #304: ``PackageMetadata`` as returned by ``metadata()`` and ``Distribution.metadata()`` now provides normalized metadata honoring PEP 566: - If a long description is provided in the payload of the RFC 822 value, it can be retrieved as the ``Description`` field. - Any multi-line values in the metadata will be returned as such. - For any multi-line values, line continuation characters are removed. This backward-incompatible change means that any projects relying on the RFC 822 line continuation characters being present must be tolerant to them having been removed. - Add a ``json`` property that provides the metadata converted to a JSON-compatible form per PEP 566. v3.10.1 ======= * Minor tweaks from CPython. v3.10.0 ======= * #295: Internal refactoring to unify section parsing logic. v3.9.1 ====== * #296: Exclude 'prepare' package. * #297: Fix ValueError when entry points contains comments. v3.9.0 ====== * Use of Mapping (dict) interfaces on ``SelectableGroups`` is now flagged as deprecated. Instead, users are advised to use the select interface for future compatibility. Suppress the warning with this filter: ``ignore:SelectableGroups dict interface``. Or with this invocation in the Python environment: ``warnings.filterwarnings('ignore', 'SelectableGroups dict interface')``. Preferably, switch to the ``select`` interface introduced in 3.7.0. See the `entry points documentation `_ and changelog for the 3.6 release below for more detail. For some use-cases, especially those that rely on ``importlib.metadata`` in Python 3.8 and 3.9 or those relying on older ``importlib_metadata`` (especially on Python 3.5 and earlier), `backports.entry_points_selectable `_ was created to ease the transition. Please have a look at that project if simply relying on importlib_metadata 3.6+ is not straightforward. Background in #298. * #283: Entry point parsing no longer relies on ConfigParser and instead uses a custom, one-pass parser to load the config, resulting in a ~20% performance improvement when loading entry points. v3.8.2 ====== * #293: Re-enabled lazy evaluation of path lookup through a FreezableDefaultDict. v3.8.1 ====== * #293: Workaround for error in distribution search. v3.8.0 ====== * #290: Add mtime-based caching for ``FastPath`` and its lookups, dramatically increasing performance for repeated distribution lookups. v3.7.3 ====== * Docs enhancements and cleanup following review in `GH-24782 `_. v3.7.2 ====== * Cleaned up cruft in entry_points docstring. v3.7.1 ====== * Internal refactoring to facilitate ``entry_points() -> dict`` deprecation. v3.7.0 ====== * #131: Added ``packages_distributions`` to conveniently resolve a top-level package or module to its distribution(s). v3.6.0 ====== * #284: Introduces new ``EntryPoints`` object, a tuple of ``EntryPoint`` objects but with convenience properties for selecting and inspecting the results: - ``.select()`` accepts ``group`` or ``name`` keyword parameters and returns a new ``EntryPoints`` tuple with only those that match the selection. - ``.groups`` property presents all of the group names. - ``.names`` property presents the names of the entry points. - Item access (e.g. ``eps[name]``) retrieves a single entry point by name. ``entry_points`` now accepts "selection parameters", same as ``EntryPoint.select()``. ``entry_points()`` now provides a future-compatible ``SelectableGroups`` object that supplies the above interface (except item access) but remains a dict for compatibility. In the future, ``entry_points()`` will return an ``EntryPoints`` object for all entry points. If passing selection parameters to ``entry_points``, the future behavior is invoked and an ``EntryPoints`` is the result. * #284: Construction of entry points using ``dict([EntryPoint, ...])`` is now deprecated and raises an appropriate DeprecationWarning and will be removed in a future version. * #300: ``Distribution.entry_points`` now presents as an ``EntryPoints`` object and access by index is no longer allowed. If access by index is required, cast to a sequence first. v3.5.0 ====== * #280: ``entry_points`` now only returns entry points for unique distributions (by name). v3.4.0 ====== * #10: Project now declares itself as being typed. * #272: Additional performance enhancements to distribution discovery. * #111: For PyPA projects, add test ensuring that ``MetadataPathFinder._search_paths`` honors the needed interface. Method is still private. v3.3.0 ====== * #265: ``EntryPoint`` objects now expose a ``.dist`` object referencing the ``Distribution`` when constructed from a Distribution. v3.2.0 ====== * The object returned by ``metadata()`` now has a formally-defined protocol called ``PackageMetadata`` with declared support for the ``.get_all()`` method. Fixes #126. v3.1.1 ====== v2.1.1 ====== * #261: Restored compatibility for package discovery for metadata without version in the name and for legacy eggs. v3.1.0 ====== * Merge with 2.1.0. v2.1.0 ====== * #253: When querying for package metadata, the lookup now honors `package normalization rules `_. v3.0.0 ====== * Require Python 3.6 or later. v2.0.0 ====== * ``importlib_metadata`` no longer presents a ``__version__`` attribute. Consumers wishing to resolve the version of the package should query it directly with ``importlib_metadata.version('importlib-metadata')``. Closes #71. v1.7.0 ====== * ``PathNotFoundError`` now has a custom ``__str__`` mentioning "package metadata" being missing to help guide users to the cause when the package is installed but no metadata is present. Closes #124. v1.6.1 ====== * Added ``Distribution._local()`` as a provisional demonstration of how to load metadata for a local package. Implicitly requires that `pep517 `_ is installed. Ref #42. * Ensure inputs to FastPath are Unicode. Closes #121. * Tests now rely on ``importlib.resources.files`` (and backport) instead of the older ``path`` function. * Support any iterable from ``find_distributions``. Closes #122. v1.6.0 ====== * Added ``module`` and ``attr`` attributes to ``EntryPoint`` v1.5.2 ====== * Fix redundant entries from ``FastPath.zip_children``. Closes #117. v1.5.1 ====== * Improve reliability and consistency of compatibility imports for contextlib and pathlib when running tests. Closes #116. v1.5.0 ====== * Additional performance optimizations in FastPath now saves an additional 20% on a typical call. * Correct for issue where PyOxidizer finder has no ``__module__`` attribute. Closes #110. v1.4.0 ====== * Through careful optimization, ``distribution()`` is 3-4x faster. Thanks to Antony Lee for the contribution. Closes #95. * When searching through ``sys.path``, if any error occurs attempting to list a path entry, that entry is skipped, making the system much more lenient to errors. Closes #94. v1.3.0 ====== * Improve custom finders documentation. Closes #105. v1.2.0 ====== * Once again, drop support for Python 3.4. Ref #104. v1.1.3 ====== * Restored support for Python 3.4 due to improper version compatibility declarations in the v1.1.0 and v1.1.1 releases. Closes #104. v1.1.2 ====== * Repaired project metadata to correctly declare the ``python_requires`` directive. Closes #103. v1.1.1 ====== * Fixed ``repr(EntryPoint)`` on PyPy 3 also. Closes #102. v1.1.0 ====== * Dropped support for Python 3.4. * EntryPoints are now pickleable. Closes #96. * Fixed ``repr(EntryPoint)`` on PyPy 2. Closes #97. v1.0.0 ====== * Project adopts semver for versioning. * Removed compatibility shim introduced in 0.23. * For better compatibility with the stdlib implementation and to avoid the same distributions being discovered by the stdlib and backport implementations, the backport now disables the stdlib DistributionFinder during initialization (import time). Closes #91 and closes #100. 0.23 ==== * Added a compatibility shim to prevent failures on beta releases of Python before the signature changed to accept the "context" parameter on find_distributions. This workaround will have a limited lifespan, not to extend beyond release of Python 3.8 final. 0.22 ==== * Renamed ``package`` parameter to ``distribution_name`` as `recommended `_ in the following functions: ``distribution``, ``metadata``, ``version``, ``files``, and ``requires``. This backward-incompatible change is expected to have little impact as these functions are assumed to be primarily used with positional parameters. 0.21 ==== * ``importlib.metadata`` now exposes the ``DistributionFinder`` metaclass and references it in the docs for extending the search algorithm. * Add ``Distribution.at`` for constructing a Distribution object from a known metadata directory on the file system. Closes #80. * Distribution finders now receive a context object that supplies ``.path`` and ``.name`` properties. This change introduces a fundamental backward incompatibility for any projects implementing a ``find_distributions`` method on a ``MetaPathFinder``. This new layer of abstraction allows this context to be supplied directly or constructed on demand and opens the opportunity for a ``find_distributions`` method to solicit additional context from the caller. Closes #85. 0.20 ==== * Clarify in the docs that calls to ``.files`` could return ``None`` when the metadata is not present. Closes #69. * Return all requirements and not just the first for dist-info packages. Closes #67. 0.19 ==== * Restrain over-eager egg metadata resolution. * Add support for entry points with colons in the name. Closes #75. 0.18 ==== * Parse entry points case sensitively. Closes #68 * Add a version constraint on the backport configparser package. Closes #66 0.17 ==== * Fix a permission problem in the tests on Windows. 0.16 ==== * Don't crash if there exists an EGG-INFO directory on sys.path. 0.15 ==== * Fix documentation. 0.14 ==== * Removed ``local_distribution`` function from the API. **This backward-incompatible change removes this behavior summarily**. Projects should remove their reliance on this behavior. A replacement behavior is under review in the `pep517 project `_. Closes #42. 0.13 ==== * Update docstrings to match PEP 8. Closes #63. * Merged modules into one module. Closes #62. 0.12 ==== * Add support for eggs. !65; Closes #19. 0.11 ==== * Support generic zip files (not just wheels). Closes #59 * Support zip files with multiple distributions in them. Closes #60 * Fully expose the public API in ``importlib_metadata.__all__``. 0.10 ==== * The ``Distribution`` ABC is now officially part of the public API. Closes #37. * Fixed support for older single file egg-info formats. Closes #43. * Fixed a testing bug when ``$CWD`` has spaces in the path. Closes #50. * Add Python 3.8 to the ``tox`` testing matrix. 0.9 === * Fixed issue where entry points without an attribute would raise an Exception. Closes #40. * Removed unused ``name`` parameter from ``entry_points()``. Closes #44. * ``DistributionFinder`` classes must now be instantiated before being placed on ``sys.meta_path``. 0.8 === * This library can now discover/enumerate all installed packages. **This backward-incompatible change alters the protocol finders must implement to support distribution package discovery.** Closes #24. * The signature of ``find_distributions()`` on custom installer finders should now accept two parameters, ``name`` and ``path`` and these parameters must supply defaults. * The ``entry_points()`` method no longer accepts a package name but instead returns all entry points in a dictionary keyed by the ``EntryPoint.group``. The ``resolve`` method has been removed. Instead, call ``EntryPoint.load()``, which has the same semantics as ``pkg_resources`` and ``entrypoints``. **This is a backward incompatible change.** * Metadata is now always returned as Unicode text regardless of Python version. Closes #29. * This library can now discover metadata for a 'local' package (found in the current-working directory). Closes #27. * Added ``files()`` function for resolving files from a distribution. * Added a new ``requires()`` function, which returns the requirements for a package suitable for parsing by ``packaging.requirements.Requirement``. Closes #18. * The top-level ``read_text()`` function has been removed. Use ``PackagePath.read_text()`` on instances returned by the ``files()`` function. **This is a backward incompatible change.** * Release dates are now automatically injected into the changelog based on SCM tags. 0.7 === * Fixed issue where packages with dashes in their names would not be discovered. Closes #21. * Distribution lookup is now case-insensitive. Closes #20. * Wheel distributions can no longer be discovered by their module name. Like Path distributions, they must be indicated by their distribution package name. 0.6 === * Removed ``importlib_metadata.distribution`` function. Now the public interface is primarily the utility functions exposed in ``importlib_metadata.__all__``. Closes #14. * Added two new utility functions ``read_text`` and ``metadata``. 0.5 === * Updated README and removed details about Distribution class, now considered private. Closes #15. * Added test suite support for Python 3.4+. * Fixed SyntaxErrors on Python 3.4 and 3.5. !12 * Fixed errors on Windows joining Path elements. !15 0.4 === * Housekeeping. 0.3 === * Added usage documentation. Closes #8 * Add support for getting metadata from wheels on ``sys.path``. Closes #9 0.2 === * Added ``importlib_metadata.entry_points()``. Closes #1 * Added ``importlib_metadata.resolve()``. Closes #12 * Add support for Python 2.7. Closes #4 0.1 === * Initial release. ..
