Misc#

v63.1.0#

03 Jul 2022

Changes#

v63.0.0#

04 Jul 2022

Breaking Changes#

  • #3421: Drop setuptools’ support for installing an entrypoint extra requirements at load time: - the functionality has been broken since v60.8.0. - the mechanism to do so is deprecated (fetch_build_eggs). - that use case (e.g. a custom command class entrypoint) is covered by making sure the necessary build requirements are declared.

Documentation changes#

  • #3305: Updated the example pyproject.toml – by @jacalata

  • #3394: This updates the documentation for the file_finders hook so that the logging recommendation aligns with the suggestion to not use distutils directly.

  • #3397: Fix reference for keywords to point to the Core Metadata Specification instead of PEP 314 (the live standard is kept always up-to-date and consolidates several PEPs together in a single document).

  • #3402: Reordered the User Guide’s Table of Contents – by @codeandfire

v62.6.0#

19 Jun 2022

Changes#

  • #3253: Enabled using file: for requirements in setup.cfg – by @akx (this feature is currently considered to be in beta stage).

  • #3255: Enabled using file: for dependencies and optional-dependencies in pyproject.toml – by @akx (this feature is currently considered to be in beta stage).

  • #3391: Updated attr: to also extract simple constants with type annotations – by @karlotness

v62.5.0#

17 Jun 2022

Changes#

  • #3347: Changed warnings and documentation notes about experimental aspect of pyproject.toml configuration: now [project] is a fully supported configuration interface, but the [tool.setuptools] table and sub-tables are still considered to be in beta stage.

  • #3383: In _distutils_hack, suppress/undo the use of local distutils when select tests are imported in CPython.

Documentation changes#

  • #3368: Added documentation page about extension modules – by @mkoeppe

  • #3371: Moved documentation from /userguide/commands to /depracted/commands. This change was motived by the fact that running python setup.py directly is considered a deprecated practice.

  • #3372: Consolidated sections about sdist contents and MANIFEST.in into a single page.

    Added a simple MANIFEST.in example.

  • #3373: Moved remarks about using Cython to the newly created page for extension modules.

  • #3374: Added clarification that using python setup.py egg_info commands to manage project versions is only supported in a transitional basis, and that eventually egg_info will be deprecated.

    Reorganized sections with tips for managing versions.

  • #3378: Updated Quickstart docs to make it easier to follow for beginners.

Misc#

  • #3385: Modules used to parse and evaluate configuration from pyproject.toml files are intended for internal use only and that not part of the public API.

v62.4.0#

13 Jun 2022

Changes#

Documentation changes#

  • #3355: Changes to the User Guide’s Entry Points page – by @codeandfire

  • #3361: Further minor corrections to the Entry Points page – by @codeandfire

  • #3363: Rework some documentation pages to de-emphasize distutils and the history of packaging in the Python ecosystem. The focus of these changes is to make the documentation easier to read for new users.

  • #3364: Update documentation about dependency management, removing mention to the deprecated dependency_links and adding some small improvements.

  • #3367: Extracted text about automatic resource extraction and the zip-safe flag from userguide/miscellaneous to deprecated/resource_extraction and deprecated/zip_safe.

    Extracted text about additional metadata files from userguide/miscellaneous into the existing userguide/extension document.

    Updated userguide/extension to better reflect the status of the setuptools project.

    Removed userguide/functionalities_rewrite (a virtually empty part of the docs).

v62.3.4#

11 Jun 2022

Documentation changes#

  • #3349: Fixed two small issues preventing docs from building locally – by @codeandfire

  • #3350: Added note explaining package_data glob pattern matching for dotfiles – by @comabrewer

  • #3358: Clarify the role of the package_dir configuration.

Misc#

v62.3.2#

18 May 2022

Misc#

  • #3328: Include a first line summary to some of the existing multi-line warnings.

v62.3.1#

17 May 2022

Misc#

  • #3320: Fixed typo which causes namespace_packages to raise an error instead of warning.

v62.3.0#

16 May 2022

Deprecations#

  • #3262: Formally added deprecation messages for namespace_packages. The methodology that uses pkg_resources and namespace_packages for creating namespaces was already discouraged by the setuptools docs and the Python Packaging User Guide, therefore this change just make the deprecation more official. Users can consider migrating to native/implicit namespaces (as introduced in PEP 420).

  • #3308: Relying on include_package_data to ensure sub-packages are automatically added to the build wheel distribution (as “data”) is now considered a deprecated practice.

    This behaviour was controversial and caused inconsistencies (#3260).

    Instead, projects are encouraged to properly configure packages or use discovery tools. General information can be found in Package Discovery and Namespace Packages.

Changes#

  • #1806: Allowed recursive globs (**) in package_data. – by @nullableVoidPtr

  • #3206: Fixed behaviour when both install_requires (in setup.py) and dependencies (in pyproject.toml) are specified. The configuration in pyproject.toml will take precedence over setup.py (in accordance with PEP 621). A warning was added to inform users.

Documentation changes#

  • #3307: Added introduction to references/keywords.

    Added deprecation tags to test kwargs.

    Moved userguide/keywords to deprecated section.

    Clarified in deprecated doc what keywords came from distutils and which were added or changed by setuptools.

Misc#

  • #3274: Updated version of vendored pyparsing to 3.0.8 to avoid problems with upcoming deprecation in Python 3.11.

  • #3292: Added warning about incompatibility with old versions of importlib-metadata.

v62.2.0#

10 May 2022

Changes#

Misc#

  • #3282: Added CI cache for setup.cfg examples used when testing setuptools.config.

v62.1.0#

10 Apr 2022

Changes#

Misc#

  • #3249: Simplified package_dir obtained via auto-discovery.

v62.0.0#

04 Apr 2022

Breaking Changes#

  • #3151: Made setup.py develop --user install to the user site packages directory even if it is disabled in the current interpreter.

Changes#

  • #3153: When resolving requirements use both canonical and normalized names – by @ldaniluk

  • #3167: Honor unix file mode in ZipFile when installing wheel via install_as_egg – by @delijati

Misc#

  • #3088: Fixed duplicated tag with the dist-info command.

  • #3247: Fixed problem preventing readme specified as dynamic in pyproject.toml from being dynamically specified in setup.py.

v61.3.1#

01 Apr 2022

Misc#

  • #3233: Included missing test file setupcfg_examples.txt in sdist.

  • #3233: Added script that allows developers to download setupcfg_examples.txt prior to running tests. By caching these files it should be possible to run the test suite offline.

v61.3.0#

31 Mar 2022

Changes#

  • #3229: Disabled automatic download of trove-classifiers to facilitate reproducibility.

Misc#

  • #3229: Updated pyproject.toml validation via validate-pyproject v0.7.1.

  • #3229: New internal tool made available for updating the code responsible for the validation of pyproject.toml. This tool can be executed via tox -e generate-validation-code.

v61.2.0#

27 Mar 2022

Changes#

  • #3215: Ignored a subgroup of invalid pyproject.toml files that use the [project] table to specify only requires-python (transitional).

    Warning

    Please note that future releases of setuptools will halt the build process if a pyproject.toml file that does not match doc:the PyPA Specification is given.

  • #3215: Updated pyproject.toml validation, as generated by validate-pyproject==0.6.1.

  • #3218: Prevented builds from erroring if the project specifies metadata via pyproject.toml, but uses other files (e.g. setup.py) to complement it, without setting dynamic properly.

    Important

    This is a transitional behaviour. Future releases of setuptools may simply ignore externally set metadata not backed by dynamic or even halt the build with an error.

  • #3224: Merge changes from pypa/distutils@e1d5c9b1f6

Documentation changes#

Misc#

  • #3223: Fixed missing requirements with environment markers when optional-dependencies is set in pyproject.toml.

v61.1.1#

26 Mar 2022

Misc#

  • #3212: Fixed missing dependencies when running setup.py install. Note that calling setup.py install directly is still deprecated and will be removed in future versions of setuptools. Please check the release notes for v58.3.0.

v61.1.0#

25 Mar 2022

Deprecations#

  • #3206: Changed setuptools.convert_path to an internal function that is not exposed as part of setuptools API. Future releases of setuptools are likely to remove this function.

Changes#

  • #3202: Changed behaviour of auto-discovery to not explicitly expand package_dir for flat-layouts and to not use relative paths starting with ./.

  • #3203: Prevented pyproject.toml parsing from overwriting dist.include_package_data explicitly set in setup.py with default value.

  • #3208: Added a warning for non existing files listed with the file directive in setup.cfg and pyproject.toml.

  • #3208: Added a default value for dynamic classifiers in pyproject.toml when files are missing and errors being ignored.

  • #3211: Disabled auto-discovery when distribution class has a configuration attribute (e.g. when the setup.py script contains setup(..., configuration=...)). This is done to ensure extension-only packages created with numpy.distutils.misc_util.Configuration are not broken by the safe guard behaviour to avoid accidental multiple top-level packages in a flat-layout.

    Note

    Users that don’t set packages, py_modules, or configuration are still likely to observe the auto-discovery behavior, which may halt the build if the project contains multiple directories and/or multiple Python files directly under the project root.

    To disable auto-discovery please explicitly set either packages or py_modules. Alternatively you can also configure Custom discovery.

v61.0.0#

24 Mar 2022

Deprecations#

  • #3068: Deprecated setuptools.config.read_configuration, setuptools.config.parse_configuration and other functions or classes from setuptools.config.

    Users that still need to parse and process configuration from setup.cfg can import a direct replacement from setuptools.config.setupcfg, however this module is transitional and might be removed in the future (the setup.cfg configuration format itself is likely to be deprecated in the future).

Breaking Changes#

  • #2894: If you purposefully want to create an “empty distribution”, please be aware that some Python files (or general folders) might be automatically detected and included.

    Projects that currently don’t specify both packages and py_modules in their configuration and contain extra folders or Python files (not meant for distribution), might see these files being included in the wheel archive or even experience the build to fail.

    You can check details about the automatic discovery (and how to configure a different behaviour) in Package Discovery and Namespace Packages.

  • #3067: If the file pyproject.toml exists and it includes project metadata/config (via [project] table or [tool.setuptools]), a series of new behaviors that are not backward compatible may take place:

    • The default value of include_package_data will be considered to be True.

    • Setuptools will attempt to validate the pyproject.toml file according to PEP 621 specification.

    • The values specified in pyproject.toml will take precedence over those specified in setup.cfg or setup.py.

Changes#

  • #2887: [EXPERIMENTAL] Added automatic discovery for py_modules and packages – by @abravalheri.

    Setuptools will try to find these values assuming that the package uses either the src-layout (a src directory containing all the packages or modules), the flat-layout (package directories directly under the project root), or the single-module approach (an isolated Python file, directly under the project root).

    The automatic discovery will also respect layouts that are explicitly configured using the package_dir option.

    For backward-compatibility, this behavior will be observed only if both py_modules and packages are not set. (Note: specifying ext_modules might also prevent auto-discover from taking place)

    If setuptools detects modules or packages that are not supposed to be in the distribution, please manually set py_modules and packages in your setup.cfg or setup.py file. If you are using a flat-layout, you can also consider switching to src-layout.

  • #2887: [EXPERIMENTAL] Added automatic configuration for the name metadata – by @abravalheri.

    Setuptools will adopt the name of the top-level package (or module in the case of single-module distributions), only when name is not explicitly provided.

    Please note that it is not possible to automatically derive a single name when the distribution consists of multiple top-level packages or modules.

  • #3066: Added vendored dependencies for tomli, validate-pyproject.

    These dependencies are used to read pyproject.toml files and validate them.

  • #3067: [EXPERIMENTAL] When using pyproject.toml metadata, the default value of include_package_data is changed to True.

  • #3068: [EXPERIMENTAL] Add support for pyproject.toml configuration (as introduced by PEP 621). Configuration parameters not covered by standards are handled in the [tool.setuptools] sub-table.

    In the future, existing setup.cfg configuration may be automatically converted into the pyproject.toml equivalent before taking effect (as proposed in #1688). Meanwhile users can use automated tools like ini2toml to help in the transition.

    Please note that the legacy backend is not guaranteed to work with pyproject.toml configuration.

    – by @abravalheri

  • #3125: Implicit namespaces (as introduced in PEP 420) are now considered by default during package discovery, when setuptools configuration and project metadata are added to the pyproject.toml file.

    To disable this behaviour, use namespaces = False when explicitly setting the [tool.setuptools.packages.find] section in pyproject.toml.

    This change is backwards compatible and does not affect the behaviour of configuration done in setup.cfg or setup.py.

  • #3152: [EXPERIMENTAL] Added support for attr: and cmdclass configurations in setup.cfg and pyproject.toml when package_dir is implicitly found via auto-discovery.

  • #3178: Postponed importing ctypes when hiding files on Windows. This helps to prevent errors in systems that might not have libffi installed.

  • #3179: Merge with pypa/distutils@267dbd25ac

Documentation changes#

  • #3172: Added initial documentation about configuring setuptools via pyproject.toml (using standard project metadata).

Misc#

  • #3065: Refactored setuptools.config by separating configuration parsing (specific to the configuration file format, e.g. setup.cfg) and post-processing (which includes directives such as file: that can be used across different configuration formats).

v60.10.0#

16 Mar 2022

Changes#

  • #2971: Deprecated upload_docs command, to be removed in the future.

  • #3137: Use samefile from stdlib, supported on Windows since Python 3.2.

  • #3170: Adopt nspektr (vendored) to implement Distribution._install_dependencies.

Documentation changes#

  • #3144: Added documentation on using console_scripts from setup.py, which was previously only shown in setup.cfg – by @xhlulu

  • #3148: Added clarifications about MANIFEST.in, that include links to PyPUG docs and more prominent mentions to using a revision control system plugin as an alternative.

  • #3148: Removed mention to pkg_resources as the recommended way of accessing data files, in favour of importlib.resources. Additionally more emphasis was put on the fact that package data files reside inside the package directory (and therefore should be read-only).

Misc#

  • #3120: Added workaround for intermittent failures of backend tests on PyPy. These tests now are marked with XFAIL, instead of erroring out directly.

  • #3124: Improved configuration for rst-linker (extension used to build the changelog).

  • #3133: Enhanced isolation of tests using virtual environments - PYTHONPATH is not leaking to spawned subprocesses – by @befeleme

  • #3147: Added options to provide a pre-built setuptools wheel or sdist for being used during tests with virtual environments. Paths for these pre-built distribution files can now be set via the environment variables: PRE_BUILT_SETUPTOOLS_SDIST and PRE_BUILT_SETUPTOOLS_WHEEL.

v60.9.3#

17 Feb 2022

Misc#

  • #3093: Repaired automated release process.

v60.9.2#

  • #3103: Fixed issue where string-based entry points would be omitted.

  • #3107: Bump importlib_metadata to 4.11.1 addressing issue with parsing requirements in egg-info as found in PyPy.

v60.9.0#

13 Feb 2022

Changes#

  • #2876: In the build backend, allow single config settings to be supplied.

  • #2993: Removed workaround in distutils hack for get-pip now that pypa/get-pip#137 is closed.

  • #3085: Setuptools no longer relies on pkg_resources for entry point handling.

  • #3098: Bump vendored packaging to 21.3.

  • Removed bootstrap script.

Warning

Users trying to install the unmaintained pathlib backport from PyPI/sdist/source code may find problems when using setuptools >= 60.9.0. This happens because during the installation, the unmaintained implementation of pathlib is loaded and may cause compatibility problems (it does not expose the same public API defined in the Python standard library).

Whenever possible users should avoid declaring pathlib as a dependency. An alternative is to pre-build a wheel for pathlib using a separated virtual environment with an older version of setuptools and install the library directly from the pre-built wheel.

v60.8.2#

08 Feb 2022

Misc#

  • #3091: Make concurrent.futures import lazy in vendored more_itertools package to a avoid importing threading as a side effect (which caused gevent/gevent#1865). – by @maciejp-ro

v60.7.1#

02 Feb 2022

Misc#

  • #3072: Remove lorem_ipsum from jaraco.text when vendored.

v60.7.0#

01 Feb 2022

Changes#

  • #3061: Vendored jaraco.text and use line processing from that library in pkg_resources.

Misc#

  • #3070: Avoid AttributeError in easy_install.create_home_path when sysconfig.get_config_vars values are not strings.

v60.6.0#

30 Jan 2022

Changes#

Documentation changes#

  • #2897: Added documentation about wrapping setuptools.build_meta in a in-tree custom backend. This is a PEP 517-compliant way of dynamically specifying build dependencies (e.g. when platform, OS and other markers are not enough). – by @abravalheri

  • #3034: Replaced occurrences of the defunct distutils-sig mailing list with pointers to GitHub Discussions. – by @ashemedai

  • #3056: The documentation has stopped suggesting to add wheel to PEP 517 requirements – by @webknjaz

Misc#

v60.5.4#

v60.5.0#

08 Jan 2022

Changes#

  • #2990: Set the .origin attribute of the distutils module to the module’s __file__.

v60.4.0#

08 Jan 2022

Changes#

  • #2839: Removed requires sorting when installing wheels as an egg dir.

  • #2953: Fixed a bug that easy install incorrectly parsed Python 3.10 version string.

  • #3006: Fixed startup performance issue of Python interpreter due to imports of costly modules in _distutils_hack – by @tiran

  • #2674: Added link to additional resources on packaging in Quickstart guide

  • #3008: “In-tree” Sphinx extension for “favicons” replaced with sphinx-favicon.

  • #3008: SVG images (logo, banners, …) optimised with the help of the scour package.

Misc#

  • #2862: Added integration tests that focus on building and installing some packages in the Python ecosystem via pip – by @abravalheri

  • #2952: Modified “vendoring” logic to keep license files.

  • #2968: Improved isolation for some tests that where inadvertently using the project root for builds, and therefore creating directories (e.g. build, dist, *.egg-info) that could interfere with the outcome of other tests – by @abravalheri.

  • #2968: Introduced new test fixtures venv, venv_without_setuptools, bare_venv that rely on the jaraco.envs package. These new test fixtures were also used to remove the (currently problematic) dependency on the pytest_virtualenv plugin.

  • #2968: Removed tmp_src test fixture. Previously this fixture was copying all the files and folders under the project root, including the .git directory, which is error prone and increases testing time.

    Since tmp_src was used to populate virtual environments (installing the version of setuptools under test via the source tree), it was replaced by the new setuptools_sdist and setuptools_wheel fixtures (that are build only once per session testing and can be shared between all the workers for read-only usage).

v54.0.0#

28 Feb 2021

Breaking Changes#

Changes#

  • #2355: When pip is imported as part of a build, leave distutils patched.

  • #2380: There are some setuptools specific changes in the setuptools.command.bdist_rpm module that are no longer needed, because they are part of the bdist_rpm module in distutils in Python 3.5.0. Therefore, code was removed from setuptools.command.bdist_rpm.

v50.1.0#

02 Sep 2020

Changes#

  • #2350: Setuptools reverts using the included distutils by default. Platform maintainers and system integrators and others are strongly encouraged to set SETUPTOOLS_USE_DISTUTILS=local to help identify and work through the reported issues with distutils adoption, mainly to file issues and pull requests with pypa/distutils such that distutils performs as needed across every supported environment.

v50.0.0#

20 Aug 2020

Breaking Changes#

  • #2232: Once again, Setuptools overrides the stdlib distutils on import. For environments or invocations where this behavior is undesirable, users are provided with a temporary escape hatch. If the environment variable SETUPTOOLS_USE_DISTUTILS is set to stdlib, Setuptools will fall back to the legacy behavior. Use of this escape hatch is discouraged, but it is provided to ease the transition while proper fixes for edge cases can be addressed.

Changes#

  • #2334: In MSVC module, refine text in error message.

v49.6.0#

13 Aug 2020

  • #2316: Removed warning when distutils is imported before setuptools when distutils replacement is not enabled.

v49.3.0#

09 Aug 2020

Changes#

  • #2259: Setuptools now provides a .pth file (except for editable installs of setuptools) to the target environment to ensure that when enabled, the setuptools-provided distutils is preferred before setuptools has been imported (and even if setuptools is never imported). Honors the SETUPTOOLS_USE_DISTUTILS environment variable.

v49.2.1#

02 Aug 2020

Misc#

  • #2257: Fixed two flaws in distutils._msvccompiler.MSVCCompiler.spawn.

v49.2.0#

12 Jul 2020

Changes#

  • #2230: Now warn the user when setuptools is imported after distutils modules have been loaded (exempting PyPy for 3.6), directing the users of packages to import setuptools first.

v49.1.3#

12 Jul 2020

Misc#

  • #2212: (Distutils) Allow spawn to accept environment. Avoid monkey-patching global state.

  • #2249: Fix extension loading technique in stubs.

v49.1.2#

11 Jul 2020

Changes#

  • #2232: In preparation for re-enabling a local copy of distutils, Setuptools now honors an environment variable, SETUPTOOLS_USE_DISTUTILS. If set to ‘stdlib’ (current default), distutils will be used from the standard library. If set to ‘local’ (default in a imminent backward-incompatible release), the local copy of distutils will be used.

v49.1.1#

10 Jul 2020

Misc#

  • #2094: Removed pkg_resources.py2_warn module, which is no longer reachable.

v49.0.1#

  • #2228: Applied fix for pypa/distutils#3, restoring expectation that spawn will raise a DistutilsExecError when attempting to execute a missing file.

v49.1.0#

03 Jul 2020

Changes#

  • #2228: Disabled distutils adoption for now while emergent issues are addressed.

v49.0.0#

03 Jul 2020

Breaking Changes#

  • #2165: Setuptools no longer installs a site.py file during easy_install or develop installs. As a result, .eggs on PYTHONPATH will no longer take precedence over other packages on sys.path. If this issue affects your production environment, please reach out to the maintainers at #2165.

Changes#

  • #2137: Removed (private) pkg_resources.RequirementParseError, now replaced by packaging.requirements.InvalidRequirement. Kept the name for compatibility, but users should catch InvalidRequirement instead.

  • #2180: Update vendored packaging in pkg_resources to 19.2.

Misc#

  • #2199: Fix exception causes all over the codebase by using raise new_exception from old_exception

v48.0.0#

03 Jul 2020

Breaking Changes#

  • #2143: Setuptools adopts distutils from the Python 3.9 standard library and no longer depends on distutils in the standard library. When importing setuptools or setuptools.distutils_patch, Setuptools will expose its bundled version as a top-level distutils package (and unload any previously-imported top-level distutils package), retaining the expectation that distutils’ objects are actually Setuptools objects. To avoid getting any legacy behavior from the standard library, projects are advised to always “import setuptools” prior to importing anything from distutils. This behavior happens by default when using pip install or pep517.build. Workflows that rely on setup.py (anything) will need to first ensure setuptools is imported. One way to achieve this behavior without modifying code is to invoke Python thus: python -c "import setuptools; exec(open('setup.py').read())" (anything).

v47.3.2#

03 Jul 2020

Misc#

  • #2071: Replaced references to the deprecated imp package with references to importlib

v47.2.0#

15 Jun 2020

v46.4.0#

16 May 2020

Changes#

v43.0.0#

31 Dec 2019

Breaking Changes#

Changes#

  • #1927: Setuptools once again declares ‘setuptools’ in the build-system.requires and adds PEP 517 build support by declaring itself as the build-backend. It additionally specifies build-system.backend-path to rely on itself for those builders that support it.

v42.0.2#

01 Dec 2019

Changes#

  • #1921: Fix support for easy_install’s find-links option in setup.cfg.

v42.0.0#

23 Nov 2019

Breaking Changes#

  • #1830, #1909: Mark the easy_install script and setuptools command as deprecated, and use pip when available to fetch/build wheels for missing setup_requires/tests_require requirements, with the following differences in behavior:

    • support for python_requires

    • better support for wheels (proper handling of priority with respect to PEP 425 tags)

    • PEP 517/518 support

    • eggs are not supported

    • no support for the allow_hosts easy_install option (index_url/find_links are still honored)

  • #1878: Formally deprecated the test command, with the recommendation that users migrate to tox.

Documentation changes#

  • #1860: Update documentation to mention the egg format is not supported by pip and dependency links support was dropped starting with pip 19.0.

  • #1862: Drop ez_setup documentation: deprecated for some time (last updated in 2016), and still relying on easy_install (deprecated too).

  • #1868: Drop most documentation references to (deprecated) EasyInstall.

v41.2.0#

21 Aug 2019

Changes#

Misc#

v41.1.0#

13 Aug 2019

Misc#

  • #1697: Moved most of the constants from setup.py to setup.cfg

  • #1749: Fixed issue with the PEP 517 backend where building a source distribution would fail if any tarball existed in the destination directory.

  • #1750: Fixed an issue with PEP 517 backend where wheel builds would fail if the destination directory did not already exist.

  • #1756: Force metadata-version >= 1.2. when project urls are present.

  • #1769: Improve package_data check: ensure the dictionary values are lists/tuples of strings.

  • #1788: Changed compatibility fallback logic for html.unescape to avoid accessing HTMLParser.unescape when not necessary. HTMLParser.unescape is deprecated and will be removed in Python 3.9.

  • #1790: Added the file path to the error message when a UnicodeDecodeError occurs while reading a metadata file.

Documentation changes#

  • #1776: Use license classifiers rather than the license field.

v41.0.0#

05 Apr 2019

Breaking Changes#

  • #1735: When parsing setup.cfg files, setuptools now requires the files to be encoded as UTF-8. Any other encoding will lead to a UnicodeDecodeError. This change removes support for specifying an encoding using a ‘coding: ‘ directive in the header of the file, a feature that was introduces in 40.7. Given the recent release of the aforementioned feature, it is assumed that few if any projects are utilizing the feature to specify an encoding other than UTF-8.

v40.9.0#

03 Apr 2019

Changes#

  • #1675: Added support for setup.cfg-only projects when using the setuptools.build_meta backend. Projects that have enabled PEP 517 no longer need to have a setup.py and can use the purely declarative setup.cfg configuration file instead.

  • #1720: Added support for pkg_resources.parse_requirements-style requirements in setup_requires when setup.py is invoked from the setuptools.build_meta build backend.

  • #1664: Added the path to the PKG-INFO or METADATA file in the exception text when the Version: header can’t be found.

  • #1705: Removed some placeholder documentation sections referring to deprecated features.

v40.8.0#

05 Feb 2019

Changes#

  • #1652: Added the build_meta:__legacy__ backend, a “compatibility mode” PEP 517 backend that can be used as the default when build-backend is left unspecified in pyproject.toml.

  • #1635: Resource paths are passed to pkg_resources.resource_string and similar no longer accept paths that traverse parents, that begin with a leading /. Violations of this expectation raise DeprecationWarnings and will become errors. Additionally, any paths that are absolute on Windows are strictly disallowed and will raise ValueErrors.

  • #1536: setuptools will now automatically include licenses if setup.cfg contains a license_file attribute, unless this file is manually excluded inside MANIFEST.in.

v40.7.3#

03 Feb 2019

Changes#

  • #1670: In package_index, revert to using a copy of splituser from Python 3.8. Attempts to use urllib.parse.urlparse led to problems as reported in #1663 and #1668. This change serves as an alternative to #1499 and fixes #1668.

v40.7.2#

31 Jan 2019

Changes#

  • #1666: Restore port in URL handling in package_index.

v40.7.1#

Changes#

  • #1180: Add support for non-ASCII in setup.cfg (#1062). Add support for native strings on some parameters (#1136).

  • #1499: setuptools.package_index no longer relies on the deprecated urllib.parse.splituser per Python #27485.

  • #1544: Added tests for PackageIndex.download (for git URLs).

  • #1625: In PEP 517 build_meta builder, ensure that sdists are built as gztar per the spec.

v40.6.3#

11 Dec 2018

Changes#

  • #1594: PEP 517 backend no longer declares setuptools as a dependency as it can be assumed.

v40.6.2#

13 Nov 2018

Changes#

  • #1592: Fix invalid dependency on external six module (instead of vendored version).

v40.6.1#

12 Nov 2018

Changes#

  • #1590: Fixed regression where packages without author or author_email fields generated malformed package metadata.

v40.6.0#

12 Nov 2018

Deprecations#

  • #1541: Officially deprecated the requires parameter in setup().

Changes#

  • #1519: In pkg_resources.normalize_path, additional path normalization is now performed to ensure path values to a directory is always the same, preventing false positives when checking scripts have a consistent prefix to set up on Windows.

  • #1545: Changed the warning class of all deprecation warnings; deprecation warning classes are no longer derived from DeprecationWarning and are thus visible by default.

  • #1554: build_meta.build_sdist now includes setup.py in source distributions by default.

  • #1576: Started monkey-patching get_metadata_version and read_pkg_file onto distutils.DistributionMetadata to retain the correct version on the PKG-INFO file in the (deprecated) upload command.

v40.4.0#

18 Sep 2018

Changes#

  • #1481: Join the sdist --dist-dir and the build_meta sdist directory argument to point to the same target (meaning the build frontend no longer needs to clean manually the dist dir to avoid multiple sdist presence, and setuptools no longer needs to handle conflicts between the two).

16 Sep 2018

Changes#

  • #1402: Fixed a bug with namespace packages under Python 3.6 when one package in current directory hides another which is installed.

v36.0.0#

30 May 2017

  • #980 and others: Once again, Setuptools vendors all of its dependencies. It seems to be the case that in the Python ecosystem, all build tools must run without any dependencies (build, runtime, or otherwise). At such a point that a mechanism exists that allows build tools to have dependencies, Setuptools will adopt it.

  • #992: Revert change introduced in v34.4.1, now considered invalid.

  • #1016: Revert change introduced in v35.0.0 per #1014, referencing #436. The approach had unintended consequences, causing sdist installs to be missing files.

v35.0.0#

15 Apr 2017

  • #436: In egg_info.manifest_maker, no longer read the file list from the manifest file, and instead re-build it on each build. In this way, files removed from the specification will not linger in the manifest. As a result, any files manually added to the manifest will be removed on subsequent egg_info invocations. No projects should be manually adding files to the manifest and should instead use MANIFEST.in or SCM file finders to force inclusion of files in the manifest.

v34.4.1#

10 Apr 2017

  • #1008: In MSVC support, use always the last version available for Windows SDK and UCRT SDK.

  • #1008: In MSVC support, fix “vcruntime140.dll” returned path with Visual Studio 2017.

  • #992: In msvc.msvc9_query_vcvarsall, ensure the returned dicts have str values and not Unicode for compatibility with os.environ.

v34.4.0#

07 Apr 2017

  • #995: In MSVC support, add support for “Microsoft Visual Studio 2017” and “Microsoft Visual Studio Build Tools 2017”.

  • #999 via #1007: Extend support for declarative package config in a setup.cfg file to include the options python_requires and py_modules.

v34.3.3#

26 Mar 2017

  • #967 (and #997): Explicitly import submodules of packaging to account for environments where the imports of those submodules is not implied by other behavior.

v34.3.2#

11 Mar 2017

  • #993: Fix documentation upload by correcting rendering of content-type in _build_multipart on Python 3.

v34.3.1#

02 Mar 2017

  • #988: Trap os.unlink same as os.remove in auto_chmod error handler.

  • #983: Fixes to invalid escape sequence deprecations on Python 3.6.

v34.3.0#

23 Feb 2017

  • #941: In the upload command, if the username is blank, default to getpass.getuser().

  • #971: Correct distutils findall monkeypatch to match appropriate versions (namely Python 3.4.6).

v34.2.0#

12 Feb 2017

  • #966: Add support for reading dist-info metadata and thus locating Distributions from zip files.

  • #968: Allow ‘+’ and ‘!’ in egg fragments so that it can take package names that contain PEP 440 conforming version specifiers.

v34.1.1#

03 Feb 2017

  • #953: More aggressively employ the compatibility issue originally added in #706.

v34.1.0#

28 Jan 2017

  • #930: build_info now accepts two new parameters to optimize and customize the building of C libraries.

v34.0.3#

28 Jan 2017

  • #947: Loosen restriction on the version of six required, restoring compatibility with environments relying on six 1.6.0 and later.

v34.0.2#

24 Jan 2017

  • #882: Ensure extras are honored when building the working set.

  • #913: Fix issue in develop if package directory has a trailing slash.

v34.0.1#

23 Jan 2017

  • #935: Fix glob syntax in graft.

v34.0.0#

23 Jan 2017

  • #581: Instead of vendoring the growing list of dependencies that Setuptools requires to function, Setuptools now requires these dependencies just like any other project. Unlike other projects, however, Setuptools cannot rely on setup_requires to demand the dependencies it needs to install because its own machinery would be necessary to pull those dependencies if not present (a bootstrapping problem). As a result, Setuptools no longer supports self upgrade or installation in the general case. Instead, users are directed to use pip to install and upgrade using the wheel distributions of setuptools.

    Users are welcome to contrive other means to install or upgrade Setuptools using other means, such as pre-installing the Setuptools dependencies with pip or a bespoke bootstrap tool, but such usage is not recommended and is not supported.

    As discovered in #940, not all versions of pip will successfully install Setuptools from its pre-built wheel. If you encounter issues with “No module named six” or “No module named packaging”, especially following a line “Running setup.py egg_info for package setuptools”, then your pip is not new enough.

    There’s an additional issue in pip where setuptools is upgraded concurrently with other source packages, described in pip #4253. The proposed workaround is to always upgrade Setuptools first prior to upgrading other packages that would upgrade Setuptools.

v33.1.1#

16 Jan 2017

  • #921: Correct issue where certifi fallback not being reached on Windows.

v33.1.0#

15 Jan 2017

Installation via pip, as indicated in the Python Packaging User’s Guide, is the officially-supported mechanism for installing Setuptools, and this recommendation is now explicit in the much more concise README.

Other edits and tweaks were made to the documentation. The codebase is unchanged.

v33.0.0#

01 Jan 2017

  • #619: Removed support for the tag_svn_revision distribution option. If Subversion tagging support is still desired, consider adding the functionality to setuptools_svn in setuptools_svn #2.

v32.3.1#

28 Dec 2016

  • #866: Use dis.Bytecode on Python 3.4 and later in setuptools.depends.

v32.3.0#

24 Dec 2016

  • #889: Backport proposed fix for disabling interpolation in distutils.Distribution.parse_config_files.

v32.2.0#

22 Dec 2016

  • #884: Restore support for running the tests under pytest-runner by ensuring that PYTHONPATH is honored in tests invoking a subprocess.

v32.1.3#

21 Dec 2016

  • #706: Add rmtree compatibility shim for environments where rmtree fails when passed a unicode string.

v32.1.2#

18 Dec 2016

  • #893: Only release sdist in zip format as warehouse now disallows releasing two different formats.

v32.1.1#

18 Dec 2016

  • #704: More selectively ensure that ‘rmtree’ is not invoked with a byte string, enabling it to remove files that are non-ascii, even on Python 2.

  • #712: In ‘sandbox.run_setup’, ensure that __file__ is always a str, modeling the behavior observed by the interpreter when invoking scripts and modules.

v32.1.0#

16 Dec 2016

  • #891: In ‘test’ command on test failure, raise DistutilsError, suppression invocation of subsequent commands.

v32.0.0#

14 Dec 2016

  • #890: Revert #849. global-exclude .foo will not match all *.foo files any more. Package authors must add an explicit wildcard, such as global-exclude *.foo, to match all .foo files. See #886, #849.

v31.0.1#

14 Dec 2016

  • #885: Fix regression where ‘pkg_resources._rebuild_mod_path’ would fail when a namespace package’s ‘__path__’ was not a list with a sort attribute.

v31.0.0#

11 Dec 2016

  • #250: Install ‘-nspkg.pth’ files for packages installed with ‘setup.py develop’. These .pth files allow namespace packages installed by pip or develop to co-mingle. This change required the removal of the change for #805 and pip #1924, introduced in 28.3.0 and implicated in #870, but means that namespace packages not in a site packages directory will no longer work on Python earlier than 3.5, whereas before they would work on Python not earlier than 3.3.

v30.4.0#

10 Dec 2016

  • #879: For declarative config:

    • read_configuration() now accepts ignore_option_errors argument. This allows scraping tools to read metadata without a need to download entire packages. E.g. we can gather some stats right from GitHub repos just by downloading setup.cfg.

    • packages find: directive now supports fine tuning from a subsection. The same arguments as for find() are accepted.

v30.3.0#

08 Dec 2016

v30.2.1#

08 Dec 2016

  • #850: In test command, invoke unittest.main with indication not to exit the process.

v30.2.0#

04 Dec 2016

v30.1.0#

03 Dec 2016

  • #846: Also trap ‘socket.error’ when opening URLs in package_index.

  • #849: Manifest processing now matches the filename pattern anywhere in the filename and not just at the start. Restores behavior found prior to 28.5.0.

v30.0.0#

01 Dec 2016

  • #864: Drop support for Python 3.2. Systems requiring Python 3.2 support must use ‘setuptools < 30’.

  • #825: Suppress warnings for single files.

  • #830 via #843: Once again restored inclusion of data files to sdists, but now trap TypeError caused by techniques employed rjsmin and similar.

v29.0.1#

26 Nov 2016

  • #861: Re-release of v29.0.1 with the executable script launchers bundled. Now, launchers are included by default and users that want to disable this behavior must set the environment variable ‘SETUPTOOLS_INSTALL_WINDOWS_SPECIFIC_FILES’ to a false value like “false” or “0”.

v29.0.0#

25 Nov 2016

  • #841: Drop special exception for packages invoking win32com during the build/install process. See Distribute #118 for history.

v28.8.0#

04 Nov 2016

  • #629: Per the discussion, refine the sorting to use version value order for more accurate detection of the latest available version when scanning for packages. See also #829.

  • #837: Rely on the config var “SO” for Python 3.3.0 only when determining the ext filename.

v28.7.1#

29 Oct 2016

  • #827: Update PyPI root for dependency links.

  • #833: Backed out changes from #830 as the implementation seems to have problems in some cases.

v28.7.0#

28 Oct 2016

  • #832: Moved much of the namespace package handling functionality into a separate module for re-use in something like #789.

  • #830: sdist command no longer suppresses the inclusion of data files, re-aligning with the expectation of distutils and addressing #274 and #521.

v28.6.1#

19 Oct 2016

  • #816: Fix manifest file list order in tests.

v28.6.0#

16 Oct 2016

  • #629: When scanning for packages, pkg_resources now ignores empty egg-info directories and gives precedence to packages whose versions are lexicographically greatest, a rough approximation for preferring the latest available version.

v28.5.0#

14 Oct 2016

  • #810: Tests are now invoked with tox and not setup.py test.

  • #249 and #450 via #764: Avoid scanning the whole tree when building the manifest. Also fixes a long-standing bug where patterns in MANIFEST.in had implicit wildcard matching. This caused global-exclude .foo to exclude all *.foo files, but also global-exclude bar.py to exclude foo_bar.py.

v28.4.0#

14 Oct 2016

  • #732: Now extras with a hyphen are honored per PEP 426.

  • #811: Update to pyparsing 2.1.10.

  • Updated setuptools.command.sdist to re-use most of the functionality directly from distutils.command.sdist for the add_defaults method with strategic overrides. See #750 for rationale.

  • #760 via #762: Look for certificate bundle where SUSE Linux typically presents it. Use certifi.where() to locate the bundle.

v28.3.0#

07 Oct 2016

  • #809: In find_packages(), restore support for excluding a parent package without excluding a child package.

  • #805: Disable -nspkg.pth behavior on Python 3.3+ where PEP-420 functionality is adequate. Fixes pip #1924.

v28.1.0#

01 Oct 2016

  • #803: Bump certifi to 2016.9.26.

v28.0.0#

27 Sep 2016

  • #733: Do not search excluded directories for packages. This introduced a backwards incompatible change in find_packages() so that find_packages(exclude=['foo']) == [], excluding subpackages of foo. Previously, find_packages(exclude=['foo']) == ['foo.bar'], even though the parent foo package was excluded.

  • #795: Bump certifi.

  • #719: Suppress decoding errors and instead log a warning when metadata cannot be decoded.

v27.3.1#

27 Sep 2016

  • #790: In MSVC monkeypatching, explicitly patch each function by name in the target module instead of inferring the module from the function’s __module__. Improves compatibility with other packages that might have previously patched distutils functions (i.e. NumPy).

v27.3.0#

20 Sep 2016

  • #794: In test command, add installed eggs to PYTHONPATH when invoking tests so that subprocesses will also have the dependencies available. Fixes tox 330.

  • #795: Update vendored pyparsing 2.1.9.

v27.2.0#

14 Sep 2016

  • #520 and #513: Suppress ValueErrors in fixup_namespace_packages when lookup fails.

  • Nicer, more consistent interfaces for msvc monkeypatching.

v27.1.2#

09 Sep 2016

v27.1.1#

09 Sep 2016

  • #778: Fix MSVC monkeypatching.

v27.1.0#

09 Sep 2016

  • Introduce the (private) monkey module to encapsulate the distutils monkeypatching behavior.

v27.0.0#

09 Sep 2016

  • Now use Warehouse by default for upload, patching distutils.config.PyPIRCCommand to affect default behavior.

    Any config in .pypirc should be updated to replace

    with

    Similarly, any passwords stored in the keyring should be updated to use this new value for “system”.

    The upload_docs command will continue to use the python.org site, but the command is now deprecated. Users are urged to use Read The Docs instead.

  • #776: Use EXT_SUFFIX for py_limited_api renaming.

  • #774 and #775: Use LegacyVersion from packaging when detecting numpy versions.

v26.1.1#

29 Aug 2016

  • Re-release of 26.1.0 with pytest pinned to allow for automated deployment and thus proper packaging environment variables, fixing issues with missing executable launchers.

v26.1.0#

28 Aug 2016

  • #763: pkg_resources.get_default_cache now defers to the appdirs project to resolve the cache directory. Adds a vendored dependency on appdirs to pkg_resources.

v26.0.0#

20 Aug 2016

  • #748: By default, sdists are now produced in gzipped tarfile format by default on all platforms, adding forward compatibility for the same behavior in Python 3.6 (See Python #27819).

  • #459 via #736: On Windows with script launchers, sys.argv[0] now reflects the name of the entry point, consistent with the behavior in distlib and pip wrappers.

  • #752 via #753: When indicating py_limited_api to Extension, it must be passed as a keyword argument.

v25.4.0#

19 Aug 2016

  • Add Extension(py_limited_api=True). When set to a truthy value, that extension gets a filename appropriate for code using Py_LIMITED_API. When used correctly this allows a single compiled extension to work on all future versions of CPython 3. The py_limited_api argument only controls the filename. To be compatible with multiple versions of Python 3, the C extension will also need to set -DPy_LIMITED_API=… and be modified to use only the functions in the limited API.

v25.3.0#

19 Aug 2016

  • #739 Fix unquoted libpaths by fixing compatibility between numpy.distutils and distutils._msvccompiler for numpy < 1.11.2 (Fix issue #728, error also fixed in Numpy).

  • #731: Bump certifi.

  • Style updates. See #740, #741, #743, #744, #742, #747.

  • #735: include license file.

v25.2.0#

12 Aug 2016

  • #612 via #730: Add a LICENSE file which needs to be provided by the terms of the MIT license.

v25.1.6#

05 Aug 2016

  • #725: revert library_dir_option patch (Error is related to numpy.distutils and make errors on non Numpy users).

v25.1.5#

05 Aug 2016

  • #720

  • #723: Improve patch for library_dir_option.

v25.1.4#

04 Aug 2016

  • #717

  • #713

  • #707: Fix Python 2 compatibility for MSVC by catching errors properly.

  • #715: Fix unquoted libpaths by patching library_dir_option.

v25.1.3#

02 Aug 2016

  • #714 and #704: Revert fix as it breaks other components downstream that can’t handle unicode. See #709, #710, and #712.

v25.1.2#

01 Aug 2016

  • #704: Fix errors when installing a zip sdist that contained files named with non-ascii characters on Windows would crash the install when it attempted to clean up the build.

  • #646: MSVC compatibility - catch errors properly in RegistryInfo.lookup.

  • #702: Prevent UnboundLocalError when initial working_set is empty.

v25.1.1#

28 Jul 2016

  • #686: Fix issue in sys.path ordering by pkg_resources when rewrite technique is “raw”.

  • #699: Fix typo in msvc support.

v25.1.0#

25 Jul 2016

  • #609: Setuptools will now try to download a distribution from the next possible download location if the first download fails. This means you can now specify multiple links as dependency_links and all links will be tried until a working download link is encountered.

v25.0.2#

25 Jul 2016

  • #688: Fix AttributeError in setup.py when invoked not from the current directory.

v25.0.1#

25 Jul 2016

  • Cleanup of setup.py script.

  • Fixed documentation builders by allowing setup.py to be imported without having bootstrapped the metadata.

  • More style cleanup. See #677, #678, #679, #681, #685.

v25.0.0#

23 Jul 2016

  • #674: Default sys.path manipulation by easy-install.pth is now “raw”, meaning that when writing easy-install.pth during any install operation, the sys.path will not be rewritten and will no longer give preference to easy_installed packages.

    To retain the old behavior when using any easy_install operation (including setup.py install when setuptools is present), set the environment variable:

    SETUPTOOLS_SYS_PATH_TECHNIQUE=rewrite

    This project hopes that that few if any environments find it necessary to retain the old behavior, and intends to drop support for it altogether in a future release. Please report any relevant concerns in the ticket for this change.

v24.3.1#

23 Jul 2016

  • #398: Fix shebang handling on Windows in script headers where spaces in sys.executable would produce an improperly-formatted shebang header, introduced in 12.0 with the fix for #188.

  • #663, #670: More style updates.

v24.3.0#

21 Jul 2016

  • #516: Disable os.link to avoid hard linking in sdist.make_distribution, avoiding errors on systems that support hard links but not on the file system in which the build is occurring.

20.4#

29 Mar 2016

  • Issue #422: Moved hosting to Github from Bitbucket. Issues have been migrated, though all issues and comments are attributed to bb-migration. So if you have a particular issue or issues to which you’ve been subscribed, you will want to “watch” the equivalent issue in Github. The Bitbucket project will be retained for the indefinite future, but Github now hosts the canonical project repository.

20.3.1#

18 Mar 2016

31 Jan 2016

  • Issue #491: Correct regression incurred in 19.4 where a double-namespace package installed using pip would cause a TypeError.

19.6.1#

29 Jan 2016

  • Restore compatibility for PyPy 3 compatibility lost in 19.4.1 addressing Issue #487.

  • setuptools.launch shim now loads scripts in a new namespace, avoiding getting relative imports from the setuptools package on Python 2.

19.6#

24 Jan 2016

  • Added a new entry script setuptools.launch, implementing the shim found in pip.util.setuptools_build. Use this command to launch distutils-only packages under setuptools in the same way that pip does, causing the setuptools monkeypatching of distutils to be invoked prior to invoking a script. Useful for debugging or otherwise installing a distutils-only package under setuptools when pip isn’t available or otherwise does not expose the desired functionality. For example:

    $ python -m setuptools.launch setup.py develop

  • Issue #488: Fix dual manifestation of Extension class in extension packages installed as dependencies when Cython is present.

19.5#

23 Jan 2016

  • Issue #486: Correct TypeError when getfilesystemencoding returns None.

  • Issue #139: Clarified the license as MIT.

  • BB Pull Request #169: Removed special handling of command spec in scripts for Jython.

19.4.1#

23 Jan 2016

  • Issue #487: Use direct invocation of importlib.machinery in pkg_resources to avoid missing detection on relevant platforms.

19.4#

16 Jan 2016

  • Issue #341: Correct error in path handling of package data files in build_py command when package is empty.

  • Distribute #323, Issue #141, Issue #207, and BB Pull Request #167: Another implementation of pkg_resources.WorkingSet and pkg_resources.Distribution that supports replacing an extant package with a new one, allowing for setup_requires dependencies to supersede installed packages for the session.

19.3#

06 Jan 2016

  • Issue #229: Implement new technique for readily incorporating dependencies conditionally from vendored copies or primary locations. Adds a new dependency on six.

19.2#

25 Dec 2015

19.1.1#

16 Dec 2015

  • Issue #476: Cast version to string (using default encoding) to avoid creating Unicode types on Python 2 clients.

  • Issue #477: In Powershell downloader, use explicit rendering of strings, rather than rely on repr, which can be incorrect (especially on Python 2).

19.1#

16 Dec 2015

  • Issue #215: The bootstrap script ez_setup.py now automatically detects the latest version of setuptools (using PyPI JSON API) rather than hard-coding a particular value.

  • Issue #475: Fix incorrect usage in _translate_metadata2.

19.0#

15 Dec 2015

  • Issue #442: Use RawConfigParser for parsing .pypirc file. Interpolated values are no longer honored in .pypirc files.

18.8.1#

13 Dec 2015

  • Issue #440: Prevent infinite recursion when a SandboxViolation or other UnpickleableException occurs in a sandbox context with setuptools hidden. Fixes regression introduced in Setuptools 12.0.

18.8#

11 Dec 2015

  • Deprecated egg_info.get_pkg_info_revision.

  • Issue #471: Don’t rely on repr for an HTML attribute value in package_index.

  • Issue #419: Avoid errors in FileMetadata when the metadata directory is broken.

  • Issue #472: Remove deprecated use of ‘U’ in mode parameter when opening files.

18.7.1#

01 Dec 2015

18.7#

28 Nov 2015

  • Update dependency on certify.

  • BB Pull Request #160: Improve detection of gui script in easy_install._adjust_header.

  • Made test.test_args a non-data property; alternate fix for the issue reported in BB Pull Request #155.

  • Issue #453: In ez_setup bootstrap module, unload all pkg_resources modules following download.

  • BB Pull Request #158: Honor PEP-488 when excluding files for namespace packages.

  • Issue #419 and BB Pull Request #144: Add experimental support for reading the version info from distutils-installed metadata rather than using the version in the filename.

18.6.1#

24 Nov 2015

  • Issue #464: Correct regression in invocation of superclass on old-style class on Python 2.

18.6#

24 Nov 2015

  • Issue #439: When installing entry_point scripts under development, omit the version number of the package, allowing any version of the package to be used.

18.5#

01 Nov 2015

18.4#

10 Oct 2015

  • Issue #446: Test command now always invokes unittest, even if no test suite is supplied.

18.3.2#

19 Sep 2015

  • Correct another regression in setuptools.findall where the fix for Python #12885 was lost.

18.3.1#

07 Sep 2015

  • Issue #425: Correct regression in setuptools.findall.

18.3#

06 Sep 2015

  • BB Pull Request #135: Setuptools now allows disabling of the manipulation of the sys.path during the processing of the easy-install.pth file. To do so, set the environment variable SETUPTOOLS_SYS_PATH_TECHNIQUE to anything but “rewrite” (consider “raw”). During any install operation with manipulation disabled, setuptools packages will be appended to sys.path naturally.

    Future versions may change the default behavior to disable manipulation. If so, the default behavior can be retained by setting the variable to “rewrite”.

  • Issue #257: easy_install --version now shows more detail about the installation location and Python version.

  • Refactor setuptools.findall in preparation for re-submission back to distutils.

18.2#

19 Aug 2015

  • Issue #412: More efficient directory search in find_packages.

18.1#

02 Aug 2015

18.0.1#

24 Jun 2015

18.0#

13 Jun 2015

  • Dropped support for builds with Pyrex. Only Cython is supported.

  • Issue #288: Detect Cython later in the build process, after setup_requires dependencies are resolved. Projects backed by Cython can now be readily built with a setup_requires dependency. For example:

    ext = setuptools.Extension('mylib', ['src/CythonStuff.pyx', 'src/CStuff.c'])
setuptools.setup(
    ...
    ext_modules=[ext],
    setup_requires=['cython'],
)

    For compatibility with older versions of setuptools, packagers should still include src/CythonMod.c in the source distributions or require that Cython be present before building source distributions. However, for systems with this build of setuptools, Cython will be downloaded on demand.

  • Issue #396: Fixed test failure on OS X.

  • BB Pull Request #136: Remove excessive quoting from shebang headers for Jython.

17.1.1#

08 Jun 2015

  • Backed out unintended changes to pkg_resources, restoring removal of deprecated imp module (ref).

17.1#

07 Jun 2015

  • Issue #380: Add support for range operators on environment marker evaluation.

17.0#

28 May 2015

  • Issue #378: Do not use internal importlib._bootstrap module.

  • Issue #390: Disallow console scripts with path separators in the name. Removes unintended functionality and brings behavior into parity with pip.

16.0#

18 May 2015

15.2#

26 Apr 2015

  • Issue #373: Provisionally expose pkg_resources._initialize_master_working_set, allowing for imperative re-initialization of the master working set.

15.1#

15 Apr 2015

15.0#

03 Apr 2015

  • BB Pull Request #126: DistributionNotFound message now lists the package or packages that required it. E.g.:

    pkg_resources.DistributionNotFound: The 'colorama>=0.3.1' distribution was not found and is required by smlib.log.

    Note that zc.buildout once dependended on the string rendering of this message to determine the package that was not found. This expectation has since been changed, but older versions of buildout may experience problems. See Buildout #242 for details.

14.3.1#

20 Mar 2015

  • Issue #307: Removed PEP-440 warning during parsing of versions in pkg_resources.Distribution.

  • Issue #364: Replace deprecated usage with recommended usage of EntryPoint.load.

14.3#

15 Mar 2015

  • Issue #254: When creating temporary egg cache on Unix, use mode 755 for creating the directory to avoid the subsequent warning if the directory is group writable.

14.2#

15 Mar 2015

  • Issue #137: Update Distribution.hashcmp so that Distributions with None for pyversion or platform can be compared against Distributions defining those attributes.

14.1.1#

14 Mar 2015

  • Issue #360: Removed undesirable behavior from test runs, preventing write tests and installation to system site packages.

14.1#

14 Mar 2015

14.0#

06 Mar 2015

  • Bootstrap script now accepts --to-dir to customize save directory or allow for re-use of existing repository of setuptools versions. See BB Pull Request #112 for background.

  • Issue #285: easy_install no longer will default to installing packages to the “user site packages” directory if it is itself installed there. Instead, the user must pass --user in all cases to install packages to the user site packages. This behavior now matches that of “pip install”. To configure an environment to always install to the user site packages, consider using the “install-dir” and “scripts-dir” parameters to easy_install through an appropriate distutils config file.

13.0.2#

06 Mar 2015

  • Issue #359: Include pytest.ini in the sdist so invocation of py.test on the sdist honors the pytest configuration.

13.0.1#

05 Mar 2015

Re-release of 13.0. Intermittent connectivity issues caused the release process to fail and PyPI uploads no longer accept files for 13.0.

13.0#

05 Mar 2015

  • Issue #356: Back out BB Pull Request #119 as it requires Setuptools 10 or later as the source during an upgrade.

  • Removed build_py class from setup.py. According to 892f439d216e, this functionality was added to support upgrades from old Distribute versions, 0.6.5 and 0.6.6.

12.4#

04 Mar 2015

  • BB Pull Request #119: Restore writing of setup_requires to metadata (previously added in 8.4 and removed in 9.0).

12.3#

26 Feb 2015

  • Documentation is now linked using the rst.linker package.

  • Fix setuptools.command.easy_install.extract_wininst_cfg() with Python 2.6 and 2.7.

  • Issue #354. Added documentation on building setuptools documentation.

12.2#

16 Feb 2015

  • Issue #345: Unload all modules under pkg_resources during ez_setup.use_setuptools().

  • Issue #336: Removed deprecation from ez_setup.use_setuptools, as it is clearly still used by buildout’s bootstrap. ez_setup remains deprecated for use by individual packages.

  • Simplified implementation of ez_setup.use_setuptools.

12.1#

10 Feb 2015

12.0.5#

26 Jan 2015

  • Issue #339: Correct Attribute reference in cant_write_to_target.

  • Issue #336: Deprecated ez_setup.use_setuptools.

12.0.4#

20 Jan 2015

  • Issue #335: Fix script header generation on Windows.

12.0.3#

18 Jan 2015

  • Fixed incorrect class attribute in install_scripts. Tests would be nice.

12.0.2#

18 Jan 2015

  • Issue #331: Fixed install_scripts command on Windows systems corrupting the header.

12.0.1#

16 Jan 2015

  • Restore setuptools.command.easy_install.sys_executable for pbr compatibility. For the future, tools should construct a CommandSpec explicitly.

12.0#

16 Jan 2015

  • Issue #188: Setuptools now support multiple entities in the value for build.executable, such that an executable of “/usr/bin/env my-python” may be specified. This means that systems with a specified executable whose name has spaces in the path must be updated to escape or quote that value.

  • Deprecated easy_install.ScriptWriter.get_writer, replaced by .best() with slightly different semantics (no force_windows flag).

11.3.1#

06 Jan 2015

  • Issue #327: Formalize and restore support for any printable character in an entry point name.

11.3#

05 Jan 2015

  • Expose EntryPoint.resolve in place of EntryPoint._load, implementing the simple, non-requiring load. Deprecated all uses of EntryPoint._load except for calling with no parameters, which is just a shortcut for ep.require(); ep.resolve();.

    Apps currently invoking ep.load(require=False) should instead do the following if wanting to avoid the deprecating warning:

    getattr(ep, "resolve", lambda: ep.load(require=False))()

11.2#

05 Jan 2015

  • Pip #2326: Report deprecation warning at stacklevel 2 for easier diagnosis.

11.1#

04 Jan 2015

  • Issue #281: Since Setuptools 6.1 (Issue #268), a ValueError would be raised in certain cases where VersionConflict was raised with two arguments, which occurred in pkg_resources.WorkingSet.find. This release adds support for indicating the dependent packages while maintaining support for a VersionConflict when no dependent package context is known. New unit tests now capture the expected interface.

11.0#

02 Jan 2015

10.2.1#

02 Jan 2015

  • Issue #323: Fix regression in entry point name parsing.

10.2#

02 Jan 2015

  • Deprecated use of EntryPoint.load(require=False). Passing a boolean to a function to select behavior is an anti-pattern. Instead use Entrypoint._load().

  • Substantial refactoring of all unit tests. Tests are now much leaner and re-use a lot of fixtures and contexts for better clarity of purpose.

10.1#

31 Dec 2014

  • Issue #320: Added a compatibility implementation of sdist._default_revctrl so that systems relying on that interface do not fail (namely, Ubuntu 12.04 and similar Debian releases).

10.0.1#

30 Dec 2014

  • Issue #319: Fixed issue installing pure distutils packages.

10.0#

30 Dec 2014

  • Issue #313: Removed built-in support for subversion. Projects wishing to retain support for subversion will need to use a third party library. The extant implementation is being ported to setuptools_svn.

  • Issue #315: Updated setuptools to hide its own loaded modules during installation of another package. This change will enable setuptools to upgrade (or downgrade) itself even when its own metadata and implementation change.

9.1#

29 Dec 2014

9.0.1#

29 Dec 2014

  • Issue #312: Restored presence of pkg_resources API tests (doctest) to sdist.

9.0#

28 Dec 2014

  • Issue #314: Disabled support for setup_requires metadata to avoid issue where Setuptools was unable to upgrade over earlier versions.

8.4#

26 Dec 2014

8.3#

24 Dec 2014

  • Issue #311: Decoupled pkg_resources from setuptools once again. pkg_resources is now a package instead of a module.

8.2.1#

18 Dec 2014

  • Issue #306: Suppress warnings about Version format except in select scenarios (such as installation).

8.2#

18 Dec 2014

8.1#

18 Dec 2014

  • Upgrade packaging to 14.5, giving preference to “rc” as designator for release candidates over “c”.

  • PEP-440 warnings are now raised as their own class, pkg_resources.PEP440Warning, instead of RuntimeWarning.

  • Disabled warnings on empty versions.

8.0.4#

15 Dec 2014

  • Upgrade packaging to 14.4, fixing an error where there is a different result for if 2.0.5 is contained within >2.0dev and >2.0.dev even though normalization rules should have made them equal.

  • Issue #296: Add warning when a version is parsed as legacy. This warning will make it easier for developers to recognize deprecated version numbers.

8.0.3#

15 Dec 2014

  • Issue #296: Restored support for __hash__ on parse_version results.

8.0.2#

14 Dec 2014

  • Issue #296: Restored support for __getitem__ and sort operations on parse_version result.

8.0.1#

13 Dec 2014

  • Issue #296: Restore support for iteration over parse_version result, but deprecated that usage with a warning. Fixes failure with buildout.

8.0#

13 Dec 2014

  • Implement PEP 440 within pkg_resources and setuptools. This change deprecates some version numbers such that they will no longer be installable without using the === escape hatch. See the changes to test_resources for specific examples of version numbers and specifiers that are no longer supported. Setuptools now “vendors” the packaging library.

7.0#

19 Oct 2014

  • Issue #80, Issue #209: Eggs that are downloaded for setup_requires, test_requires, etc. are now placed in a ./.eggs directory instead of directly in the current directory. This choice of location means the files can be readily managed (removed, ignored). Additionally, later phases or invocations of setuptools will not detect the package as already installed and ignore it for permanent install (See #209).

    This change is indicated as backward-incompatible as installations that depend on the installation in the current directory will need to account for the new location. Systems that ignore *.egg will probably need to be adapted to ignore .eggs. The files will need to be manually moved or will be retrieved again. Most use cases will require no attention.

6.1#

11 Oct 2014

  • Issue #268: When resolving package versions, a VersionConflict now reports which package previously required the conflicting version.

6.0.2#

29 Sep 2014

  • Issue #262: Fixed regression in pip install due to egg-info directories being omitted. Re-opens Issue #118.

6.0.1#

27 Sep 2014

  • Issue #259: Fixed regression with namespace package handling on single version, externally managed installs.

6.0#

27 Sep 2014

  • Issue #100: When building a distribution, Setuptools will no longer match default files using platform-dependent case sensitivity, but rather will only match the files if their case matches exactly. As a result, on Windows and other case-insensitive file systems, files with names such as ‘readme.txt’ or ‘README.TXT’ will be omitted from the distribution and a warning will be issued indicating that ‘README.txt’ was not found. Other filenames affected are:

    • README.rst

    • README

    • setup.cfg

    • setup.py (or the script name)

    • test/test*.py

    Any users producing distributions with filenames that match those above case-insensitively, but not case-sensitively, should rename those files in their repository for better portability.

  • BB Pull Request #72: When using single_version_externally_managed, the exclusion list now includes Python 3.2 __pycache__ entries.

  • BB Pull Request #76 and BB Pull Request #78: lines in top_level.txt are now ordered deterministically.

  • Issue #118: The egg-info directory is now no longer included in the list of outputs.

  • Issue #258: Setuptools now patches distutils msvc9compiler to recognize the specially-packaged compiler package for easy extension module support on Python 2.6, 2.7, and 3.2.

5.8#

18 Sep 2014

  • Issue #237: pkg_resources now uses explicit detection of Python 2 vs. Python 3, supporting environments where builtins have been patched to make Python 3 look more like Python 2.

5.7#

15 Aug 2014

  • Issue #240: Based on real-world performance measures against 5.4, zip manifests are now cached in all circumstances. The PKG_RESOURCES_CACHE_ZIP_MANIFESTS environment variable is no longer relevant. The observed “memory increase” referenced in the 5.4 release notes and detailed in Issue #154 was likely not an increase over the status quo, but rather only an increase over not storing the zip info at all.

5.6#

14 Aug 2014

  • Issue #242: Use absolute imports in svn_utils to avoid issues if the installing package adds an xml module to the path.

5.5.1#

10 Aug 2014

  • Issue #239: Fix typo in 5.5 such that fix did not take.

5.5#

10 Aug 2014

  • Issue #239: Setuptools now includes the setup_requires directive on Distribution objects and validates the syntax just like install_requires and tests_require directives.

5.4.2#

01 Aug 2014

  • Issue #236: Corrected regression in execfile implementation for Python 2.6.

5.4.1#

06 Jul 2014

  • Python #7776: (ssl_support) Correct usage of host for validation when tunneling for HTTPS.

5.4#

05 Jul 2014

  • Issue #154: pkg_resources will now cache the zip manifests rather than re-processing the same file from disk multiple times, but only if the environment variable PKG_RESOURCES_CACHE_ZIP_MANIFESTS is set. Clients that package many modules in the same zip file will see some improvement in startup time by enabling this feature. This feature is not enabled by default because it causes a substantial increase in memory usage.

5.3#

28 Jun 2014

  • Issue #185: Make svn tagging work on the new style SVN metadata. Thanks cazabon!

  • Prune revision control directories (e.g .svn) from base path as well as sub-directories.

5.2#

22 Jun 2014

  • Added a Developer Guide to the official documentation.

  • Some code refactoring and cleanup was done with no intended behavioral changes.

  • During install_egg_info, the generated lines for namespace package .pth files are now processed even during a dry run.

5.1#

15 Jun 2014

  • Issue #202: Implemented more robust cache invalidation for the ZipImporter, building on the work in Issue #168. Special thanks to Jurko Gospodnetic and PJE.

5.0.2#

15 Jun 2014

5.0.1#

14 Jun 2014

  • Renamed script templates to end with .tmpl now that they no longer need to be processed by 2to3. Fixes spurious syntax errors during build/install.

5.0#

14 Jun 2014

  • Issue #218: Re-release of 3.8.1 to signal that it supersedes 4.x.

  • Incidentally, script templates were updated not to include the triple-quote escaping.

3.7.1 and 3.8.1 and 4.0.1#

  • Issue #213: Use legacy StringIO behavior for compatibility under pbr.

  • Issue #218: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed from the available versions to install.

4.0#

01 Jun 2014

  • Issue #210: setup.py develop now copies scripts in binary mode rather than text mode, matching the behavior of the install command.

3.8#

01 Jun 2014

  • Extend Issue #197 workaround to include all Python 3 versions prior to 3.2.2.

3.7#

28 May 2014

  • Issue #193: Improved handling of Unicode filenames when building manifests.

3.6#

07 May 2014

  • Issue #203: Honor proxy settings for Powershell downloader in the bootstrap routine.

3.5.2#

07 May 2014

  • Issue #168: More robust handling of replaced zip files and stale caches. Fixes ZipImportError complaining about a ‘bad local header’.

3.5.1#

04 May 2014

  • Issue #199: Restored install._install for compatibility with earlier NumPy versions.

3.5#

03 May 2014

  • Issue #195: Follow symbolic links in find_packages (restoring behavior broken in 3.4).

  • Issue #197: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead of sys.getpreferredencoding to match the behavior on Python 2.6-3.4.

  • Issue #192: Preferred bootstrap location is now https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).

3.4.4#

11 Apr 2014

  • Issue #184: Correct failure where find_package over-matched packages when directory traversal isn’t short-circuited.

3.4.3#

07 Apr 2014

  • Issue #183: Really fix test command with Python 3.1.

3.4.2#

06 Apr 2014

  • Issue #183: Fix additional regression in test command on Python 3.1.

3.4.1#

30 Mar 2014

  • Issue #180: Fix regression in test command not caught by py.test-run tests.

3.4#

30 Mar 2014

  • Issue #176: Add parameter to the test command to support a custom test runner: –test-runner or -r.

  • Issue #177: Now assume most common invocation to install command on platforms/environments without stack support (issuing a warning). Setuptools now installs naturally on IronPython. Behavior on CPython should be unchanged.

3.3#

16 Mar 2014

  • Add include parameter to setuptools.find_packages().

3.2#

14 Mar 2014

3.1#

08 Mar 2014

  • Issue #161: Restore Features functionality to allow backward compatibility (for Features) until the uses of that functionality is sufficiently removed.

3.0.2#

06 Mar 2014

  • Correct typo in previous bugfix.

3.0.1#

06 Mar 2014

  • Issue #157: Restore support for Python 2.6 in bootstrap script where zipfile.ZipFile does not yet have support for context managers.

3.0#

04 Mar 2014

  • Issue #125: Prevent Subversion support from creating a ~/.subversion directory just for checking the presence of a Subversion repository.

  • Issue #12: Namespace packages are now imported lazily. That is, the mere declaration of a namespace package in an egg on sys.path no longer causes it to be imported when pkg_resources is imported. Note that this change means that all of a namespace package’s __init__.py files must include a declare_namespace() call in order to ensure that they will be handled properly at runtime. In 2.x it was possible to get away without including the declaration, but only at the cost of forcing namespace packages to be imported early, which 3.0 no longer does.

  • Issue #148: When building (bdist_egg), setuptools no longer adds __init__.py files to namespace packages. Any packages that rely on this behavior will need to create __init__.py files and include the declare_namespace().

  • Issue #7: Setuptools itself is now distributed as a zip archive in addition to tar archive. ez_setup.py now uses zip archive. This approach avoids the potential security vulnerabilities presented by use of tar archives in ez_setup.py. It also leverages the security features added to ZipFile.extract in Python 2.7.4.

  • Issue #65: Removed deprecated Features functionality.

  • BB Pull Request #28: Remove backport of _bytecode_filenames which is available in Python 2.6 and later, but also has better compatibility with Python 3 environments.

  • Issue #156: Fix spelling of __PYVENV_LAUNCHER__ variable.

2.2#

07 Feb 2014

  • Issue #141: Restored fix for allowing setup_requires dependencies to override installed dependencies during setup.

  • Issue #128: Fixed issue where only the first dependency link was honored in a distribution where multiple dependency links were supplied.

2.1.2#

05 Feb 2014

  • Issue #144: Read long_description using codecs module to avoid errors installing on systems where LANG=C.

2.1.1#

05 Feb 2014

  • Issue #139: Fix regression in re_finder for CVS repos (and maybe Git repos as well).

2.1#

07 Jan 2014

  • Issue #129: Suppress inspection of *.whl files when searching for files in a zip-imported file.

01 Dec 2013

  • Issue #116: Correct TypeError when reading a local package index on Python 3.

1.4.1#

23 Nov 2013

  • Issue #114: Use sys.getfilesystemencoding for decoding config in bdist_wininst distributions.

  • Issue #105 and Issue #113: Establish a more robust technique for determining the terminal encoding:

    1. Try ``getpreferredencoding``
2. If that returns US_ASCII or None, try the encoding from
   ``getdefaultlocale``. If that encoding was a "fallback" because Python
   could not figure it out from the environment or OS, encoding remains
   unresolved.
3. If the encoding is resolved, then make sure Python actually implements
   the encoding.
4. On the event of an error or unknown codec, revert to fallbacks
   (UTF-8 on Darwin, ASCII on everything else).
5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
   a bug on older Python releases.

On a side note, it would seem that the encoding only matters for when SVN
does not yet support ``--xml`` and when getting repository and svn version
numbers. The ``--xml`` technique should yield UTF-8 according to some
messages on the SVN mailing lists. So if the version numbers are always
7-bit ASCII clean, it may be best to only support the file parsing methods
for legacy SVN releases and support for SVN without the subprocess command
would simple go away as support for the older SVNs does.

1.2#

02 Nov 2013

  • Issue #26: Add support for SVN 1.7. Special thanks to Philip Thiem for the contribution.

  • Issue #93: Wheels are now distributed with every release. Note that as reported in Issue #108, as of Pip 1.4, scripts aren’t installed properly from wheels. Therefore, if using Pip to install setuptools from a wheel, the easy_install command will not be available.

  • Setuptools “natural” launcher support, introduced in 1.0, is now officially supported.

1.1.7#

11 Apr 2013

  • Issue #72: Restored Python 2.4 compatibility in ez_setup.py.

1.0#

17 Aug 2013

  • Issue #60: On Windows, Setuptools supports deferring to another launcher, such as Vinay Sajip’s pylauncher (included with Python 3.3) to launch console and GUI scripts and not install its own launcher executables. This experimental functionality is currently only enabled if the SETUPTOOLS_LAUNCHER environment variable is set to “natural”. In the future, this behavior may become default, but only after it has matured and seen substantial adoption. The SETUPTOOLS_LAUNCHER also accepts “executable” to force the default behavior of creating launcher executables.

  • Issue #63: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or wget for retrieving the Setuptools tarball for improved security of the install. The script will still fall back to a simple urlopen on platforms that do not have these tools.

  • Issue #65: Deprecated the Features functionality.

  • Issue #52: In VerifyingHTTPSConn, handle a tunnelled (proxied) connection.

Backward-Incompatible Changes#

This release includes a couple of backward-incompatible changes, but most if not all users will find 1.0 a drop-in replacement for 0.9.

  • Issue #50: Normalized API of environment marker support. Specifically, removed line number and filename from SyntaxErrors when returned from pkg_resources.invalid_marker. Any clients depending on the specific string representation of exceptions returned by that function may need to be updated to account for this change.

  • Issue #50: SyntaxErrors generated by pkg_resources.invalid_marker are normalized for cross-implementation consistency.

  • Removed --ignore-conflicts-at-my-risk and --delete-conflicting options to easy_install. These options have been deprecated since 0.6a11.

0.9.8#

02 Jun 2013

  • Merged Setuptools and Distribute. See docs/merge.txt for details.

Added several features that were slated for setuptools 0.6c12:

  • Index URL now defaults to HTTPS.

  • Added experimental environment marker support. Now clients may designate a PEP-426 environment marker for “extra” dependencies. Setuptools uses this feature in setup.py for optional SSL and certificate validation support on older platforms. Based on Distutils-SIG discussions, the syntax is somewhat tentative. There should probably be a PEP with a firmer spec before the feature should be considered suitable for use.

  • Added support for SSL certificate validation when installing packages from an HTTPS service.

0.7b4#

05 Apr 2013

  • BB Pull Request #35: In Buildout #64, it was reported that under Python 3, installation of distutils scripts could attempt to copy the __pycache__ directory as a file, causing an error, apparently only under Windows. Easy_install now skips all directories when processing metadata scripts.

0.6.35#

  • Corrected inconsistency between documentation and code of add_entry. This closes Distribute #8.

  • Immediately close all file handles. This closes Distribute #3.

easy_install#

0.6c9#

  • Fixed a missing files problem when using Windows source distributions on non-Windows platforms, due to distutils not handling manifest file line endings correctly.

  • Updated Pyrex support to work with Pyrex 0.9.6 and higher.

  • Minor changes for Jython compatibility, including skipping tests that can’t work on Jython.

  • Fixed not installing eggs in install_requires if they were also used for setup_requires or tests_require.

  • Fixed not fetching eggs in install_requires when running tests.

  • Allow ez_setup.use_setuptools() to upgrade existing setuptools installations when called from a standalone setup.py.

  • Added a warning if a namespace package is declared, but its parent package is not also declared as a namespace.

  • Support Subversion 1.5

  • Removed use of deprecated md5 module if hashlib is available

  • Fixed bdist_wininst upload trying to upload the .exe twice

  • Fixed bdist_egg putting a native_libs.txt in the source package’s .egg-info, when it should only be in the built egg’s EGG-INFO.

  • Ensure that _full_name is set on all shared libs before extensions are checked for shared lib usage. (Fixes a bug in the experimental shared library build support.)

  • Fix to allow unpacked eggs containing native libraries to fail more gracefully under Google App Engine (with an ImportError loading the C-based module, instead of getting a NameError).

  • Fixed win32.exe support for .pth files, so unnecessary directory nesting is flattened out in the resulting egg. (There was a case-sensitivity problem that affected some distributions, notably pywin32.)

  • Prevent --help-commands and other junk from showing under Python 2.5 when running easy_install --help.

  • Fixed GUI scripts sometimes not executing on Windows

  • Fixed not picking up dependency links from recursive dependencies.

  • Only make .py, .dll and .so files executable when unpacking eggs

  • Changes for Jython compatibility

  • Improved error message when a requirement is also a directory name, but the specified directory is not a source package.

  • Fixed --allow-hosts option blocking file: URLs

  • Fixed HTTP SVN detection failing when the page title included a project name (e.g. on SourceForge-hosted SVN)

  • Fix Jython script installation to handle #! lines better when sys.executable is a script.

  • Removed use of deprecated md5 module if hashlib is available

  • Keep site directories (e.g. site-packages) from being included in .pth files.

0.6c7#

  • Fixed distutils.filelist.findall() crashing on broken symlinks, and egg_info command failing on new, uncommitted SVN directories.

  • Fix import problems with nested namespace packages installed via --root or --single-version-externally-managed, due to the parent package not having the child package as an attribute.

  • ftp: download URLs now work correctly.

  • The default --index-url is now https://pypi.python.org/simple, to use the Python Package Index’s new simpler (and faster!) REST API.

0.6c6#

  • Added --egg-path option to develop command, allowing you to force .egg-link files to use relative paths (allowing them to be shared across platforms on a networked drive).

  • Fix not building binary RPMs correctly.

  • Fix “eggsecutables” (such as setuptools’ own egg) only being runnable with bash-compatible shells.

  • Fix #! parsing problems in Windows .exe script wrappers, when there was whitespace inside a quoted argument or at the end of the #! line (a regression introduced in 0.6c4).

  • Fix test command possibly failing if an older version of the project being tested was installed on sys.path ahead of the test source directory.

  • Fix find_packages() treating ez_setup and directories with . in their names as packages.

  • EasyInstall no longer aborts the installation process if a URL it wants to retrieve can’t be downloaded, unless the URL is an actual package download. Instead, it issues a warning and tries to keep going.

  • Fixed distutils-style scripts originally built on Windows having their line endings doubled when installed on any platform.

  • Added --local-snapshots-ok flag, to allow building eggs from projects installed using setup.py develop.

  • Fixed not HTML-decoding URLs scraped from web pages

0.6c5#

  • Fix uploaded bdist_rpm packages being described as bdist_egg packages under Python versions less than 2.5.

  • Fix uploaded bdist_wininst packages being described as suitable for “any” version by Python 2.5, even if a --target-version was specified.

  • Fixed .dll files on Cygwin not having executable permissions when an egg is installed unzipped.

0.6c4#

  • Overhauled Windows script wrapping to support bdist_wininst better. Scripts installed with bdist_wininst will always use #!python.exe or #!pythonw.exe as the executable name (even when built on non-Windows platforms!), and the wrappers will look for the executable in the script’s parent directory (which should find the right version of Python).

  • Fix upload command not uploading files built by bdist_rpm or bdist_wininst under Python 2.3 and 2.4.

  • Add support for “eggsecutable” headers: a #!/bin/sh script that is prepended to an .egg file to allow it to be run as a script on Unix-ish platforms. (This is mainly so that setuptools itself can have a single-file installer on Unix, without doing multiple downloads, dealing with firewalls, etc.)

  • Fix problem with empty revision numbers in Subversion 1.4 entries files

  • Use cross-platform relative paths in easy-install.pth when doing develop and the source directory is a subdirectory of the installation target directory.

  • Fix a problem installing eggs with a system packaging tool if the project contained an implicit namespace package; for example if the setup() listed a namespace package foo.bar without explicitly listing foo as a namespace package.

  • Added support for HTTP “Basic” authentication using http://user:pass@host URLs. If a password-protected page contains links to the same host (and protocol), those links will inherit the credentials used to access the original page.

  • Removed all special support for Sourceforge mirrors, as Sourceforge’s mirror system now works well for non-browser downloads.

  • Fixed not recognizing win32.exe installers that included a custom bitmap.

  • Fixed not allowing os.open() of paths outside the sandbox, even if they are opened read-only (e.g. reading /dev/urandom for random numbers, as is done by os.urandom() on some platforms).

  • Fixed a problem with .pth testing on Windows when sys.executable has a space in it (e.g., the user installed Python to a Program Files directory).

0.6c3#

  • Fixed breakages caused by Subversion 1.4’s new “working copy” format

  • You can once again use “python -m easy_install” with Python 2.4 and above.

  • Python 2.5 compatibility fixes added.

0.6c2#

  • The ez_setup module displays the conflicting version of setuptools (and its installation location) when a script requests a version that’s not available.

  • Running setup.py develop on a setuptools-using project will now install setuptools if needed, instead of only downloading the egg.

  • Windows script wrappers now support quoted arguments and arguments containing spaces. (Patch contributed by Jim Fulton.)

  • The ez_setup.py script now actually works when you put a setuptools .egg alongside it for bootstrapping an offline machine.

  • A writable installation directory on sys.path is no longer required to download and extract a source distribution using --editable.

  • Generated scripts now use -x on the #! line when sys.executable contains non-ASCII characters, to prevent deprecation warnings about an unspecified encoding when the script is run.

0.6c1#

  • Fixed AttributeError when trying to download a setup_requires dependency when a distribution lacks a dependency_links setting.

  • Made zip-safe and not-zip-safe flag files contain a single byte, so as to play better with packaging tools that complain about zero-length files.

  • Made setup.py develop respect the --no-deps option, which it previously was ignoring.

  • Support extra_path option to setup() when install is run in backward-compatibility mode.

  • Source distributions now always include a setup.cfg file that explicitly sets egg_info options such that they produce an identical version number to the source distribution’s version number. (Previously, the default version number could be different due to the use of --tag-date, or if the version was overridden on the command line that built the source distribution.)

  • EasyInstall now includes setuptools version information in the User-Agent string sent to websites it visits.

0.6b4#

  • Fix register not obeying name/version set by egg_info command, if egg_info wasn’t explicitly run first on the same command line.

  • Added --no-date and --no-svn-revision options to egg_info command, to allow suppressing tags configured in setup.cfg.

  • Fixed redundant warnings about missing README file(s); it should now appear only if you are actually a source distribution.

  • Fix creating Python wrappers for non-Python scripts

  • Fix ftp:// directory listing URLs from causing a crash when used in the “Home page” or “Download URL” slots on PyPI.

  • Fix sys.path_importer_cache not being updated when an existing zipfile or directory is deleted/overwritten.

  • Fix not recognizing HTML 404 pages from package indexes.

  • Allow file:// URLs to be used as a package index. URLs that refer to directories will use an internally-generated directory listing if there is no index.html file in the directory.

  • Allow external links in a package index to be specified using rel="homepage" or rel="download", without needing the old PyPI-specific visible markup.

  • Suppressed warning message about possibly-misspelled project name, if an egg or link for that project name has already been seen.

0.6b3#

  • Fix bdist_egg not including files in subdirectories of .egg-info.

  • Allow .py files found by the include_package_data option to be automatically included. Remove duplicate data file matches if both include_package_data and package_data are used to refer to the same files.

  • Fix local --find-links eggs not being copied except with --always-copy.

  • Fix sometimes not detecting local packages installed outside of “site” directories.

  • Fix mysterious errors during initial setuptools install, caused by ez_setup trying to run easy_install twice, due to a code fallthru after deleting the egg from which it’s running.

0.6b2#

  • Don’t install or update a site.py patch when installing to a PYTHONPATH directory with --multi-version, unless an easy-install.pth file is already in use there.

  • Construct .pth file paths in such a way that installing an egg whose name begins with import doesn’t cause a syntax error.

  • Fixed a bogus warning message that wasn’t updated since the 0.5 versions.

0.6b1#

  • Strip module from the end of compiled extension modules when computing the name of a .py loader/wrapper. (Python’s import machinery ignores this suffix when searching for an extension module.)

  • Better ambiguity management: accept #egg name/version even if processing what appears to be a correctly-named distutils file, and ignore .egg files with no -, since valid Python .egg files always have a version number (but Scheme eggs often don’t).

  • Support file:// links to directories in --find-links, so that easy_install can build packages from local source checkouts.

  • Added automatic retry for Sourceforge mirrors. The new download process is to first just try dl.sourceforge.net, then randomly select mirror IPs and remove ones that fail, until something works. The removed IPs stay removed for the remainder of the run.

  • Ignore bdist_dumb distributions when looking at download URLs.

0.6a11#

  • Added test_loader keyword to support custom test loaders

  • Added setuptools.file_finders entry point group to allow implementing revision control plugins.

  • Added --identity option to upload command.

  • Added dependency_links to allow specifying URLs for --find-links.

  • Enhanced test loader to scan packages as well as modules, and call additional_tests() if present to get non-unittest tests.

  • Support namespace packages in conjunction with system packagers, by omitting the installation of any __init__.py files for namespace packages, and adding a special .pth file to create a working package in sys.modules.

  • Made --single-version-externally-managed automatic when --root is used, so that most system packagers won’t require special support for setuptools.

  • Fixed setup_requires, tests_require, etc. not using setup.cfg or other configuration files for their option defaults when installing, and also made the install use --multi-version mode so that the project directory doesn’t need to support .pth files.

  • MANIFEST.in is now forcibly closed when any errors occur while reading it. Previously, the file could be left open and the actual error would be masked by problems trying to remove the open file on Windows systems.

  • Process dependency_links.txt if found in a distribution, by adding the URLs to the list for scanning.

  • Use relative paths in .pth files when eggs are being installed to the same directory as the .pth file. This maximizes portability of the target directory when building applications that contain eggs.

  • Added easy_install-N.N script(s) for convenience when using multiple Python versions.

  • Added automatic handling of installation conflicts. Eggs are now shifted to the front of sys.path, in an order consistent with where they came from, making EasyInstall seamlessly co-operate with system package managers.

    The --delete-conflicting and --ignore-conflicts-at-my-risk options are now no longer necessary, and will generate warnings at the end of a run if you use them.

  • Don’t recursively traverse subdirectories given to --find-links.

0.6a10#

  • Fixed the develop command ignoring --find-links.

  • Added exhaustive testing of the install directory, including a spawn test for .pth file support, and directory writability/existence checks. This should virtually eliminate the need to set or configure --site-dirs.

  • Added --prefix option for more do-what-I-mean-ishness in the absence of RTFM-ing. :)

  • Enhanced PYTHONPATH support so that you don’t have to put any eggs on it manually to make it work. --multi-version is no longer a silent default; you must explicitly use it if installing to a non-PYTHONPATH, non-“site” directory.

  • Expand $variables used in the --site-dirs, --build-directory, --install-dir, and --script-dir options, whether on the command line or in configuration files.

  • Improved SourceForge mirror processing to work faster and be less affected by transient HTML changes made by SourceForge.

  • PyPI searches now use the exact spelling of requirements specified on the command line or in a project’s install_requires. Previously, a normalized form of the name was used, which could lead to unnecessary full-index searches when a project’s name had an underscore (_) in it.

  • EasyInstall can now download bare .py files and wrap them in an egg, as long as you include an #egg=name-version suffix on the URL, or if the .py file is listed as the “Download URL” on the project’s PyPI page. This allows third parties to “package” trivial Python modules just by linking to them (e.g. from within their own PyPI page or download links page).

  • The --always-copy option now skips “system” and “development” eggs since they can’t be reliably copied. Note that this may cause EasyInstall to choose an older version of a package than what you expected, or it may cause downloading and installation of a fresh version of what’s already installed.

  • The --find-links option previously scanned all supplied URLs and directories as early as possible, but now only directories and direct archive links are scanned immediately. URLs are not retrieved unless a package search was already going to go online due to a package not being available locally, or due to the use of the --update or -U option.

  • Fixed the annoying --help-commands wart.

0.6a9#

  • The sdist command no longer uses the traditional MANIFEST file to create source distributions. MANIFEST.in is still read and processed, as are the standard defaults and pruning. But the manifest is built inside the project’s .egg-info directory as SOURCES.txt, and it is rebuilt every time the egg_info command is run.

  • Added the include_package_data keyword to setup(), allowing you to automatically include any package data listed in revision control or MANIFEST.in

  • Added the exclude_package_data keyword to setup(), allowing you to trim back files included via the package_data and include_package_data options.

  • Fixed --tag-svn-revision not working when run from a source distribution.

  • Added warning for namespace packages with missing declare_namespace()

  • Added tests_require keyword to setup(), so that e.g. packages requiring nose to run unit tests can make this dependency optional unless the test command is run.

  • Made all commands that use easy_install respect its configuration options, as this was causing some problems with setup.py install.

  • Added an unpack_directory() driver to setuptools.archive_util, so that you can process a directory tree through a processing filter as if it were a zipfile or tarfile.

  • Added an internal install_egg_info command to use as part of old-style install operations, that installs an .egg-info directory with the package.

  • Added a --single-version-externally-managed option to the install command so that you can more easily wrap a “flat” egg in a system package.

  • Enhanced bdist_rpm so that it installs single-version eggs that don’t rely on a .pth file. The --no-egg option has been removed, since all RPMs are now built in a more backwards-compatible format.

  • Support full roundtrip translation of eggs to and from bdist_wininst format. Running bdist_wininst on a setuptools-based package wraps the egg in an .exe that will safely install it as an egg (i.e., with metadata and entry-point wrapper scripts), and easy_install can turn the .exe back into an .egg file or directory and install it as such.

  • Fixed .pth file processing picking up nested eggs (i.e. ones inside “baskets”) when they weren’t explicitly listed in the .pth file.

  • If more than one URL appears to describe the exact same distribution, prefer the shortest one. This helps to avoid “table of contents” CGI URLs like the ones on effbot.org.

  • Quote arguments to python.exe (including python’s path) to avoid problems when Python (or a script) is installed in a directory whose name contains spaces on Windows.

  • Support full roundtrip translation of eggs to and from bdist_wininst format. Running bdist_wininst on a setuptools-based package wraps the egg in an .exe that will safely install it as an egg (i.e., with metadata and entry-point wrapper scripts), and easy_install can turn the .exe back into an .egg file or directory and install it as such.

0.6a8#

  • Fixed some problems building extensions when Pyrex was installed, especially with Python 2.4 and/or packages using SWIG.

  • Made develop command accept all the same options as easy_install, and use the easy_install command’s configuration settings as defaults.

  • Made egg_info --tag-svn-revision fall back to extracting the revision number from PKG-INFO in case it is being run on a source distribution of a snapshot taken from a Subversion-based project.

  • Automatically detect .dll, .so and .dylib files that are being installed as data, adding them to native_libs.txt automatically.

  • Fixed some problems with fresh checkouts of projects that don’t include .egg-info/PKG-INFO under revision control and put the project’s source code directly in the project directory. If such a package had any requirements that get processed before the egg_info command can be run, the setup scripts would fail with a “Missing ‘Version:’ header and/or PKG-INFO file” error, because the egg runtime interpreted the unbuilt metadata in a directory on sys.path (i.e. the current directory) as being a corrupted egg. Setuptools now monkeypatches the distribution metadata cache to pretend that the egg has valid version information, until it has a chance to make it actually be so (via the egg_info command).

  • Update for changed SourceForge mirror format

  • Fixed not installing dependencies for some packages fetched via Subversion

  • Fixed dependency installation with --always-copy not using the same dependency resolution procedure as other operations.

  • Fixed not fully removing temporary directories on Windows, if a Subversion checkout left read-only files behind

  • Fixed some problems building extensions when Pyrex was installed, especially with Python 2.4 and/or packages using SWIG.

0.6a7#

  • Fixed not being able to install Windows script wrappers using Python 2.3

0.6a6#

  • Added support for “traditional” PYTHONPATH-based non-root installation, and also the convenient virtual-python.py script, based on a contribution by Ian Bicking. The setuptools egg now contains a hacked site module that makes the PYTHONPATH-based approach work with .pth files, so that you can get the full EasyInstall feature set on such installations.

  • Added --no-deps and --allow-hosts options.

  • Improved Windows .exe script wrappers so that the script can have the same name as a module without confusing Python.

  • Changed dependency processing so that it’s breadth-first, allowing a depender’s preferences to override those of a dependee, to prevent conflicts when a lower version is acceptable to the dependee, but not the depender. Also, ensure that currently installed/selected packages aren’t given precedence over ones desired by a package being installed, which could cause conflict errors.

0.6a5#

  • Fixed missing gui/cli .exe files in distribution. Fixed bugs in tests.

0.6a3#

  • Added gui_scripts entry point group to allow installing GUI scripts on Windows and other platforms. (The special handling is only for Windows; other platforms are treated the same as for console_scripts.)

  • Improved error message when trying to use old ways of running easy_install. Removed the ability to run via python -m or by running easy_install.py; easy_install is the command to run on all supported platforms.

  • Improved wrapper script generation and runtime initialization so that a VersionConflict doesn’t occur if you later install a competing version of a needed package as the default version of that package.

  • Fixed a problem parsing version numbers in #egg= links.

0.6a2#

  • Added console_scripts entry point group to allow installing scripts without the need to create separate script files. On Windows, console scripts get an .exe wrapper so you can just type their name. On other platforms, the scripts are written without a file extension.

  • EasyInstall can now install “console_scripts” defined by packages that use setuptools and define appropriate entry points. On Windows, console scripts get an .exe wrapper so you can just type their name. On other platforms, the scripts are installed without a file extension.

  • Using python -m easy_install or running easy_install.py is now DEPRECATED, since an easy_install wrapper is now available on all platforms.

0.6a1#

  • Added support for building “old-style” RPMs that don’t install an egg for the target package, using a --no-egg option.

  • The build_ext command now works better when using the --inplace option and multiple Python versions. It now makes sure that all extensions match the current Python version, even if newer copies were built for a different Python version.

  • The upload command no longer attaches an extra .zip when uploading eggs, as PyPI now supports egg uploads without trickery.

  • The ez_setup script/module now displays a warning before downloading the setuptools egg, and attempts to check the downloaded egg against an internal MD5 checksum table.

  • Fixed the --tag-svn-revision option of egg_info not finding the latest revision number; it was using the revision number of the directory containing setup.py, not the highest revision number in the project.

  • Added eager_resources setup argument

  • The sdist command now recognizes Subversion “deleted file” entries and does not include them in source distributions.

  • setuptools now embeds itself more thoroughly into the distutils, so that other distutils extensions (e.g. py2exe, py2app) will subclass setuptools’ versions of things, rather than the native distutils ones.

  • Added entry_points and setup_requires arguments to setup(); setup_requires allows you to automatically find and download packages that are needed in order to build your project (as opposed to running it).

  • setuptools now finds its commands, setup() argument validators, and metadata writers using entry points, so that they can be extended by third-party packages. See Creating distutils Extensions for more details.

  • The vestigial depends command has been removed. It was never finished or documented, and never would have worked without EasyInstall - which it pre-dated and was never compatible with.

  • EasyInstall now does MD5 validation of downloads from PyPI, or from any link that has an “#md5=…” trailer with a 32-digit lowercase hex md5 digest.

  • EasyInstall now handles symlinks in target directories by removing the link, rather than attempting to overwrite the link’s destination. This makes it easier to set up an alternate Python “home” directory (as described in the Non-Root Installation section of the docs).

  • Added support for handling MacOS platform information in .egg filenames, based on a contribution by Kevin Dangoor. You may wish to delete and reinstall any eggs whose filename includes “darwin” and “Power_Macintosh”, because the format for this platform information has changed so that minor OS X upgrades (such as 10.4.1 to 10.4.2) do not cause eggs built with a previous OS version to become obsolete.

  • easy_install’s dependency processing algorithms have changed. When using --always-copy, it now ensures that dependencies are copied too. When not using --always-copy, it tries to use a single resolution loop, rather than recursing.

  • Fixed installing extra .pyc or .pyo files for scripts with .py extensions.

  • Added --site-dirs option to allow adding custom “site” directories. Made easy-install.pth work in platform-specific alternate site directories (e.g. ~/Library/Python/2.x/site-packages on Mac OS X).

  • If you manually delete the current version of a package, the next run of EasyInstall against the target directory will now remove the stray entry from the easy-install.pth file.

  • EasyInstall now recognizes URLs with a #egg=project_name fragment ID as pointing to the named project’s source checkout. Such URLs have a lower match precedence than any other kind of distribution, so they’ll only be used if they have a higher version number than any other available distribution, or if you use the --editable option. The #egg fragment can contain a version if it’s formatted as #egg=proj-ver, where proj is the project name, and ver is the version number. You must use the format for these values that the bdist_egg command uses; i.e., all non-alphanumeric runs must be condensed to single underscore characters.

  • Added the --editable option; see Editing and Viewing Source Packages in the docs. Also, slightly changed the behavior of the --build-directory option.

  • Fixed the setup script sandbox facility not recognizing certain paths as valid on case-insensitive platforms.

0.5a12#

  • The zip-safety scanner now checks for modules that might be used with python -m, and marks them as unsafe for zipping, since Python 2.4 can’t handle -m on zipped modules.

  • Fix python -m easy_install not working due to setuptools being installed as a zipfile. Update safety scanner to check for modules that might be used as python -m scripts.

  • Misc. fixes for win32.exe support, including changes to support Python 2.4’s changed bdist_wininst format.

0.5a11#

  • Fix breakage of the “develop” command that was caused by the addition of --always-unzip to the easy_install command.

0.5a10#

  • Put the easy_install module back in as a module, as it’s needed for python -m to run it!

  • Allow --find-links/-f to accept local directories or filenames as well as URLs.

0.5a9#

  • Include svn:externals directories in source distributions as well as normal subversion-controlled files and directories.

  • Added exclude=patternlist option to setuptools.find_packages()

  • Changed –tag-svn-revision to include an “r” in front of the revision number for better readability.

  • Added ability to build eggs without including source files (except for any scripts, of course), using the --exclude-source-files option to bdist_egg.

  • setup.py install now automatically detects when an “unmanaged” package or module is going to be on sys.path ahead of a package being installed, thereby preventing the newer version from being imported. If this occurs, a warning message is output to sys.stderr, but installation proceeds anyway. The warning message informs the user what files or directories need deleting, and advises them they can also use EasyInstall (with the --delete-conflicting option) to do it automatically.

  • The egg_info command now adds a top_level.txt file to the metadata directory that lists all top-level modules and packages in the distribution. This is used by the easy_install command to find possibly-conflicting “unmanaged” packages when installing the distribution.

  • Added zip_safe and namespace_packages arguments to setup(). Added package analysis to determine zip-safety if the zip_safe flag is not given, and advise the author regarding what code might need changing.

  • Fixed the swapped -d and -b options of bdist_egg.

  • EasyInstall now automatically detects when an “unmanaged” package or module is going to be on sys.path ahead of a package you’re installing, thereby preventing the newer version from being imported. By default, it will abort installation to alert you of the problem, but there are also new options (--delete-conflicting and --ignore-conflicts-at-my-risk) available to change the default behavior. (Note: this new feature doesn’t take effect for egg files that were built with older setuptools versions, because they lack the new metadata file required to implement it.)

  • The easy_install distutils command now uses DistutilsError as its base error type for errors that should just issue a message to stderr and exit the program without a traceback.

  • EasyInstall can now be given a path to a directory containing a setup script, and it will attempt to build and install the package there.

  • EasyInstall now performs a safety analysis on module contents to determine whether a package is likely to run in zipped form, and displays information about what modules may be doing introspection that would break when running as a zipfile.

  • Added the --always-unzip/-Z option, to force unzipping of packages that would ordinarily be considered safe to unzip, and changed the meaning of --zip-ok/-z to “always leave everything zipped”.

0.5a8#

  • The “egg_info” command now always sets the distribution metadata to “safe” forms of the distribution name and version, so that distribution files will be generated with parseable names (i.e., ones that don’t include ‘-’ in the name or version). Also, this means that if you use the various --tag options of “egg_info”, any distributions generated will use the tags in the version, not just egg distributions.

  • Added support for defining command aliases in distutils configuration files, under the “[aliases]” section. To prevent recursion and to allow aliases to call the command of the same name, a given alias can be expanded only once per command-line invocation. You can define new aliases with the “alias” command, either for the local, global, or per-user configuration.

  • Added “rotate” command to delete old distribution files, given a set of patterns to match and the number of files to keep. (Keeps the most recently-modified distribution files matching each pattern.)

  • Added “saveopts” command that saves all command-line options for the current invocation to the local, global, or per-user configuration file. Useful for setting defaults without having to hand-edit a configuration file.

  • Added a “setopt” command that sets a single option in a specified distutils configuration file.

  • There is now a separate documentation page for setuptools; revision history that’s not specific to EasyInstall has been moved to that page.

0.5a7#

  • Added “upload” support for egg and source distributions, including a bug fix for “upload” and a temporary workaround for lack of .egg support in PyPI.

0.5a6#

  • Beefed up the “sdist” command so that if you don’t have a MANIFEST.in, it will include all files under revision control (CVS or Subversion) in the current directory, and it will regenerate the list every time you create a source distribution, not just when you tell it to. This should make the default “do what you mean” more often than the distutils’ default behavior did, while still retaining the old behavior in the presence of MANIFEST.in.

  • Fixed the “develop” command always updating .pth files, even if you specified -n or --dry-run.

  • Slightly changed the format of the generated version when you use --tag-build on the “egg_info” command, so that you can make tagged revisions compare lower than the version specified in setup.py (e.g. by using --tag-build=dev).

0.5a5#

  • Added develop command to setuptools-based packages. This command installs an .egg-link pointing to the package’s source directory, and script wrappers that execfile() the source versions of the package’s scripts. This lets you put your development checkout(s) on sys.path without having to actually install them. (To uninstall the link, use use setup.py develop --uninstall.)

  • Added egg_info command to setuptools-based packages. This command just creates or updates the “projectname.egg-info” directory, without building an egg. (It’s used by the bdist_egg, test, and develop commands.)

  • Enhanced the test command so that it doesn’t install the package, but instead builds any C extensions in-place, updates the .egg-info metadata, adds the source directory to sys.path, and runs the tests directly on the source. This avoids an “unmanaged” installation of the package to site-packages or elsewhere.

  • Made easy_install a standard setuptools command, moving it from the easy_install module to setuptools.command.easy_install. Note that if you were importing or extending it, you must now change your imports accordingly. easy_install.py is still installed as a script, but not as a module.

0.5a4#

  • Setup scripts using setuptools can now list their dependencies directly in the setup.py file, without having to manually create a depends.txt file. The install_requires and extras_require arguments to setup() are used to create a dependencies file automatically. If you are manually creating depends.txt right now, please switch to using these setup arguments as soon as practical, because depends.txt support will be removed in the 0.6 release cycle. For documentation on the new arguments, see the setuptools.dist.Distribution class.

  • Setup scripts using setuptools now always install using easy_install internally, for ease of uninstallation and upgrading.

  • Added --always-copy/-a option to always copy needed packages to the installation directory, even if they’re already present elsewhere on sys.path. (In previous versions, this was the default behavior, but now you must request it.)

  • Added --upgrade/-U option to force checking PyPI for latest available version(s) of all packages requested by name and version, even if a matching version is available locally.

  • Added automatic installation of dependencies declared by a distribution being installed. These dependencies must be listed in the distribution’s EGG-INFO directory, so the distribution has to have declared its dependencies by using setuptools. If a package has requirements it didn’t declare, you’ll still have to deal with them yourself. (E.g., by asking EasyInstall to find and install them.)

  • Added the --record option to easy_install for the benefit of tools that run setup.py install --record=filename on behalf of another packaging system.)

0.5a3#

  • Fixed not setting script permissions to allow execution.

  • Improved sandboxing so that setup scripts that want a temporary directory (e.g. pychecker) can still run in the sandbox.

0.5a2#

  • Fix stupid stupid refactoring-at-the-last-minute typos. :(

0.5a1#

  • Added support for “self-installation” bootstrapping. Packages can now include ez_setup.py in their source distribution, and add the following to their setup.py, in order to automatically bootstrap installation of setuptools as part of their setup process:

    from ez_setup import use_setuptools
use_setuptools()

from setuptools import setup
# etc...

  • Added support for converting .win32.exe installers to eggs on the fly. EasyInstall will now recognize such files by name and install them.

  • Fixed a problem with picking the “best” version to install (versions were being sorted as strings, rather than as parsed values)

0.4a4#

  • Added support for the distutils “verbose/quiet” and “dry-run” options, as well as the “optimize” flag.

  • Support downloading packages that were uploaded to PyPI (by scanning all links on package pages, not just the homepage/download links).

0.4a3#

  • Add progress messages to the search/download process so that you can tell what URLs it’s reading to find download links. (Hopefully, this will help people report out-of-date and broken links to package authors, and to tell when they’ve asked for a package that doesn’t exist.)

0.4a2#

  • Added ez_setup.py installer/bootstrap script to make initial setuptools installation easier, and to allow distributions using setuptools to avoid having to include setuptools in their source distribution.

  • All downloads are now managed by the PackageIndex class (which is now subclassable and replaceable), so that embedders can more easily override download logic, give download progress reports, etc. The class has also been moved to the new setuptools.package_index module.

  • The Installer class no longer handles downloading, manages a temporary directory, or tracks the zip_ok option. Downloading is now handled by PackageIndex, and Installer has become an easy_install command class based on setuptools.Command.

  • There is a new setuptools.sandbox.run_setup() API to invoke a setup script in a directory sandbox, and a new setuptools.archive_util module with an unpack_archive() API. These were split out of EasyInstall to allow reuse by other tools and applications.

  • setuptools.Command now supports reinitializing commands using keyword arguments to set/reset options. Also, Command subclasses can now set their command_consumes_arguments attribute to True in order to receive an args option containing the rest of the command line.

  • Added support for installing scripts

  • Added support for setting options via distutils configuration files, and using distutils’ default options as a basis for EasyInstall’s defaults.

  • Renamed --scan-url/-s to --find-links/-f to free up -s for the script installation directory option.

  • Use urllib2 instead of urllib, to allow use of https: URLs if Python includes SSL support.

0.4a1#

  • Added --scan-url and --index-url options, to scan download pages and search PyPI for needed packages.

0.3a4#

  • Restrict --build-directory=DIR/-b DIR option to only be used with single URL installs, to avoid running the wrong setup.py.

0.3a3#

  • Added --build-directory=DIR/-b DIR option.

  • Added “installation report” that explains how to use ‘require()’ when doing a multiversion install or alternate installation directory.

  • Added SourceForge mirror auto-select (Contributed by Ian Bicking)

  • Added “sandboxing” that stops a setup script from running if it attempts to write to the filesystem outside of the build area

  • Added more workarounds for packages with quirky install_data hacks

0.3a2#

  • Added new options to bdist_egg to allow tagging the egg’s version number with a subversion revision number, the current date, or an explicit tag value. Run setup.py bdist_egg --help to get more information.

  • Added subversion download support for svn: and svn+ URLs, as well as automatic recognition of HTTP subversion URLs (Contributed by Ian Bicking)

  • Misc. bug fixes

0.3a1#

  • Initial release.

Credits#

  • The original design for the .egg format and the pkg_resources API was co-created by Phillip Eby and Bob Ippolito. Bob also implemented the first version of pkg_resources, and supplied the macOS operating system version compatibility algorithm.

  • Ian Bicking implemented many early “creature comfort” features of easy_install, including support for downloading via Sourceforge and Subversion repositories. Ian’s comments on the Web-SIG about WSGI application deployment also inspired the concept of “entry points” in eggs, and he has given talks at PyCon and elsewhere to inform and educate the community about eggs and setuptools.

  • Jim Fulton contributed time and effort to build automated tests of various aspects of easy_install, and supplied the doctests for the command-line .exe wrappers on Windows.

  • Phillip J. Eby is the seminal author of setuptools, and first proposed the idea of an importable binary distribution format for Python application plug-ins.

  • Significant parts of the implementation of setuptools were funded by the Open Source Applications Foundation, to provide a plug-in infrastructure for the Chandler PIM application. In addition, many OSAF staffers (such as Mike “Code Bear” Taylor) contributed their time and stress as guinea pigs for the use of eggs and setuptools, even before eggs were “cool”. (Thanks, guys!)

  • Tarek Ziadé is the principal author of the Distribute fork, which re-invigorated the community on the project, encouraged renewed innovation, and addressed many defects.

  • Jason R. Coombs performed the merge with Distribute, maintaining the project for several years in coordination with the Python Packaging Authority (PyPA).
