pypa/distutils#15.

Log message:
py-setuptools: Update to 50.2.0

* It seems that this fixes PLIST divergence of some packages,
  including py-libxml2 and py-cElementTree.

Changelog:
v50.2.0

    #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

    #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.

v50.0.3

    #2363: Restore link_libpython support on Python 3.7 and earlier (see \ 
pypa/distutils#9).

v50.0.2

    #2352: In distutils hack, use absolute import rather than relative to avoid \ 
bpo-30876.

Log message:
py-setuptools: update to 50.0.1.

Please note the change in 50.0.0:

"Setuptools overrides the stdlib distutils on import"

and the workaround:

"If the environment variable ``SETUPTOOLS_USE_DISTUTILS`` is set to
``stdlib``, Setuptools will fall back to the legacy behavior."

v50.0.1
-------

* #2357: Restored Python 3.5 support in distutils.util for missing \ 
`subprocess._optim_args_from_interpreter_flags`.
* #2358: Restored AIX support on Python 3.8 and earlier.
* #2361: Add Python 3.10 support to _distutils_hack. Get the 'Loader' abstract class
  from importlib.abc rather than importlib.util.abc (alias removed in Python
  3.10).

v50.0.0
-------

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

v49.6.0
-------

* #2129: In pkg_resources, no longer detect any pathname ending in .egg as a \ 
Python egg. Now the path must be an unpacked egg or a zip file.

v49.5.0
-------

* #2306: When running as a PEP 517 backend, setuptools does not try to install
  ``setup_requires`` itself. They are reported as build requirements for the
  frontend to install.

v49.4.0
-------

* #2310: Updated vendored packaging version to 20.4.

v49.3.2
-------

* #2300: Improve the ``safe_version`` function documentation
* #2297: Once again, in stubs prefer exec_module to the deprecated load_module.

v49.3.1
-------

* #2316: Removed warning when ``distutils`` is imported before ``setuptools`` \ 
when ``distutils`` replacement is not enabled.

v49.3.0
-------

* #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
-------

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

v49.2.0
-------

* #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
-------

* #2212: (Distutils) Allow spawn to accept environment. Avoid monkey-patching \ 
global state.
* #2249: Fix extension loading technique in stubs.

v49.1.2
-------

* #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
-------

* #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
-------

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

v49.0.0
-------

* #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.
* #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.
* #2199: Fix exception causes all over the codebase by using ``raise \ 
new_exception from old_exception``

Log message:
py-setuptools: update to 47.3.2.

v47.3.2
-------

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

v47.3.1
-------

* #1973: Removed ``pkg_resources.py31compat.makedirs`` in favor of the stdlib. \ 
Use ``os.makedirs()`` instead.
* #2198: Restore ``__requires__`` directive in easy-install wrapper scripts.

v47.3.0
-------

* #2197: Console script wrapper for editable installs now has a unified template \ 
and honors importlib_metadata if present for faster script execution on older \ 
Pythons.
* #2195: Fix broken entry points generated by easy-install (pip editable installs).

v47.2.0
-------

* #2194: Editable-installed entry points now load significantly faster on Python \ 
versions 3.8+.

v47.1.1
-------

* #2156: Update mailing list pointer in developer docs

Incorporate changes from v44.1.1:

* #2158: Avoid loading working set during ``Distribution.finalize_options`` \ 
prior to invoking ``_install_setup_requires``, broken since v42.0.0.

v44.1.1
-------

* #2158: Avoid loading working set during ``Distribution.finalize_options`` \ 
prior to invoking ``_install_setup_requires``, broken since v42.0.0.

v47.1.0
-------

* #2070: In wheel-to-egg conversion, use simple pkg_resources-style namespace \ 
declaration for packages that declare namespace_packages.

v47.0.0
-------

* #2094: Setuptools now actively crashes under Python 2. Python 3.5 or later is \ 
required. Users of Python 2 should use ``setuptools<45``.
* #1700: Document all supported keywords by migrating the ones from distutils.

v46.4.0
-------

* #1753: ``attr:`` now extracts variables through rudimentary examination of the AST,
  thereby supporting modules with third-party imports. If examining the AST
  fails to find the variable, ``attr:`` falls back to the old behavior of
  importing the module. Works on Python 3 only.

v46.3.1
-------

No significant changes.

v46.3.0
-------

* #2089: Package index functionality no longer attempts to remove an md5 \ 
fragment from the index URL. This functionality, added for distribute #163 is no \ 
longer relevant.
* #2041: Preserve file modes during pkg files copying, but clear read only flag \ 
for target afterwards.
* #2105: Filter ``2to3`` deprecation warnings from \ 
``TestDevelop.test_2to3_user_mode``.

v46.2.0
-------

* #2040: Deprecated the ``bdist_wininst`` command. Binary packages should be \ 
built as wheels instead.
* #2062: Change 'Mac OS X' to 'macOS' in code.
* #2075: Stop recognizing files ending with ``.dist-info`` as distribution metadata.
* #2086: Deprecate 'use_2to3' functionality. Packagers are encouraged to use \ 
single-source solutions or build tool chains to manage conversions outside of \ 
setuptools.
* #1698: Added documentation for ``build_meta`` (a bare minimum, not completed).
* #2082: Filter ``lib2to3`` ``PendingDeprecationWarning`` and \ 
``DeprecationWarning`` in tests,
  because ``lib2to3`` is `deprecated in Python 3.9 \ 
<https://bugs.python.org/issue40360>`_.

v46.1.3
-------

No significant changes.

v46.1.2
-------

* #1458: Added template for reporting Python 2 incompatibilities.

v46.1.1
-------

No significant changes.

v46.1.0
-------

* #308: Allow version number normalization to be bypassed by wrapping in a \ 
'setuptools.sic()' call.
* #1424: Prevent keeping files mode for package_data build. It may break a build \ 
if user's package data has read only flag.
* #1431: In ``easy_install.check_site_dir``, ensure the installation directory \ 
exists.
* #1563: In ``pkg_resources`` prefer ``find_spec`` (PEP 451) to ``find_module``.

Incorporate changes from v44.1.0:

* #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
* #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2
* #1994: Fixed a bug in the "setuptools.finalize_distribution_options" \ 
hook that lead to ignoring the order attribute of entry points managed by this \ 
hook.

hook.

v46.0.0
-------

* #65: Once again as in 3.0, removed the Features feature.
* #1890: Fix vendored dependencies so importing \ 
``setuptools.extern.some_module`` gives the same object as \ 
``setuptools._vendor.some_module``. This makes Metadata picklable again.
* #1899: Test suite now fails on warnings.
* #2011: Fix broken link to distutils docs on package_data
* #1991: Include pkg_resources test data in sdist, so tests can be executed from it.

-------

* #1905: Fixed defect in _imp, introduced in 41.6.0 when the 'tests' directory \ 
is not present.
* #1941: Improve editable installs with PEP 518 build isolation:

  * The ``--user`` option is now always available. A warning is issued if the \ 
user site directory is not available.
  * The error shown when the install directory is not in ``PYTHONPATH`` has been \ 
turned into a warning.
* #1981: Setuptools now declares its ``tests`` and ``docs`` dependencies in \ 
metadata (extras).
* #1985: Add support for installing scripts in environments where bdist_wininst \ 
is missing (i.e. Python 3.9).
* #1968: Add flake8-2020 to check for misuse of sys.version or sys.version_info.

v45.1.0
-------

* #1458: Add minimum sunset date and preamble to Python 2 warning.
* #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
* #1974: Add Python 3 Only Trove Classifier and remove universal wheel \ 
declaration for more complete transition from Python 2.

v45.0.0
-------

* #1458: Drop support for Python 2. Setuptools now requires Python 3.5 or later. \ 
Install setuptools using pip >=9 or pin to Setuptools <45 to maintain 2.7 \ 
support.
* #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2

Log message:
py-setuptools: updated to 44.1.1

v44.1.1
Avoid loading working set during Distribution.finalize_options prior to invoking \ 
_install_setup_requires, broken since v42.0.0.

v44.0.0
-------

* #1908: Drop support for Python 3.4.

v43.0.0
-------

* #1634: Include ``pyproject.toml`` in source distribution by
default. Projects relying on the previous behavior where
``pyproject.toml`` was excluded by default should stop relying on
that behavior or add ``exclude pyproject.toml`` to their MANIFEST.in
file.
* #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.
