Update setuptools from 75.3.0 to 78.1.0.

Changelog

78.1.0

=======

Features
--------

- Restore access to _get_vc_env with a warning. (4874)

78.0.2

=======

Bugfixes
--------

- Postponed removals of deprecated dash-separated and uppercase fields in ``setup.cfg``.
All packages with deprecated configurations are advised to move before 2026. (4911)

78.0.1

=======

Misc
----

- 4909

78.0.0

=======

Bugfixes
--------

- Reverted distutils changes that broke the monkey patching of command classes. (4902)


Deprecations and Removals
-------------------------

- Setuptools no longer accepts options containing uppercase or dash characters in ``setup.cfg``.
Please ensure to write the options in ``setup.cfg`` using the :wiki:`lower_snake_case <Snake_case>` convention
(e.g. ``Name => name``, ``install-requires => install_requires``).
This is a follow-up on deprecations introduced in
`v54.1.0 <https://setuptools.pypa.io/en/latest/history.html#v54-1-0>`_ (see 1608) and
`v54.1.1 <https://setuptools.pypa.io/en/latest/history.html#v54-1-1>`_ (see 2592).

.. note::
  This change *does not affect configurations in* ``pyproject.toml``
  (which uses the :wiki:`lower-kebab-case <Letter_caseKebab_case>` convention following the precedent set in :pep:`517`/:pep:`518`). (4870)


Misc
----

- 4904

77.0.3

=======

Bugfixes
--------

- Temporarily convert error for license glob patterns containing ``../`` into a deprecation warning
to allow an accomodation period. (4896)
- Better error messages for ``packaging.licenses`` import errors in environments with ``packaging<24.2``\.
The import statement was also deferred to spare users that are not using
license expressions. (4898)
- Avoided eagerly raising an exception when ``license-files`` is defined
simultaneously inside and outside of ``pyproject.toml``.
Instead we rely on the existing deprecation error. (4899)

77.0.2

=======

Bugfixes
--------

- Restore ``distutils.ccompiler._default_compilers`` -- by :user:`ManiacDC` (4876)
- Fixed copy pasta in ``msvc.shared_lib_format``\. (4885)

77.0.1

=======

Bugfixes
--------

- Manually fix news fragment entries causing CI to crash when building docs. (4891)

77.0.0

=======

Features
--------

- Added initial support for license expression (PEP :pep:`639 <639add-license-expression-field>`). -- by :user:`cdce8p` (4706)
- Store ``License-File``\s in ``.dist-info/licenses`` subfolder and added support for recursive globs for ``license_files`` (PEP :pep:`639 <639add-license-expression-field>`). -- by :user:`cdce8p` (4728)
- Bump core metadata version to ``2.4``\. -- by :user:`cdce8p` (4830)
- Updated vendored copy of ``wheel`` to ``v0.45.1``\. (4869)


Deprecations and Removals
-------------------------

- Added initial implementation of :pep:`639`.
Users relying on pre- :pep:`639` implementation details
(like precise license file paths inside ``dist-info`` directory)
may need to adjust their code base to avoid problems.
Deprecations and stronger validation were also introduced (4829).
- Added exception (or warning) when deprecated license classifiers are used,
according to PEP :pep:`639 <639deprecate-license-classifiers>`. (4833)
- Deprecated ``tools.setuptools.license-files`` in favor of ``project.license-files``
and added exception if ``project.license-files`` and ``tools.setuptools.license-files``
are used together. -- by :user:`cdce8p` (4837)
- Deprecated ``project.license`` as a TOML table in
``pyproject.toml``\. Users are expected to move towards using
``project.license-files`` and/or SPDX expressions (as strings) in
``pyproject.license``\.
See PEP :pep:`639 <639deprecate-license-key-table-subkeys>`. (4840)
- Added simple validation for given glob patterns in ``license-files``\:
a warning will be generated if no file is matched.
Invalid glob patterns can raise an exception.
-- thanks :user:`cdce8p` for contributions. (4838)


Misc
----

- 4734

76.1.0

=======

Features
--------

- In setuptools.msvc.EnvironmentInfo, now honor the correct paths when on an ARM host. (4786)


Bugfixes
--------

- Restored implicit distutils.ccompiler import for g-ir-scanner. (4871)
- Restore ``distutils.ccompiler.compiler_class`` -- by :user:`Avasam` (4876)

76.0.0

=======

Deprecations and Removals
-------------------------

- Synced with pypa/distutils5589d7527 including a simplified shebang generation when building scripts (4863). (4865)

75.9.1

=======

Bugfixes
--------

- Fix ImportError in distutils when configuring for linking. (4866)

75.9.0

=======

Features
--------

- Synced with pypa/distutils91f75bb98 including exporting of PyInit_pkg (pypa/distutils327) and a refactoring of the compiler classes into distutils.compilers (pypa/distutils295). (4852)

75.8.2

=======

Bugfixes
--------

- Fixed ``pkg_resources.require(...)`` to also consider standardised
``dist-info`` directories. (4856)

75.8.1

=======

Bugfixes
--------

- Fix wheel file naming to follow binary distribution specification -- by :user:`di` (4766)
- Fixed crash generating error message printed when building wheels for the
free-threaded build using the limited API. -- by :user:`ngoldbaum` (4809)
- Fix documentation for recent CFLAGS distutils change. -- by :user:`thesamesam` (4836)

75.8.0

=======

Features
--------

- Implemented ``Dynamic`` field for core metadata (as introduced in PEP 643).
The existing implementation is currently experimental and the exact approach
may change in future releases. (4698)

75.7.0

=======

Features
--------

- Synced with pypa/distutilsc97a3db2f including better support for free threaded Python on Windows (pypa/distutils310), improved typing support, and linter accommodations. (4478)
- Synced with pypa/distutilsff11eed0c including bugfix for duplicate CFLAGS and adaption to support Python 3.13 is_abs in the C compiler (4669). (4790)

75.6.0

=======

Features
--------

- Preserve original ``PKG-INFO`` into ``METADATA`` when creating wheel
(instead of calling ``wheel.metadata.pkginfo_to_metadata``).
This helps to be more compliant with the flow specified in PEP 517. (4701)
- Changed the ``WindowsSdkVersion``, ``FrameworkVersion32`` and ``FrameworkVersion64`` properties of ``setuptools.msvc.PlatformInfo`` to return an empty `tuple` instead of `None` as a fallthrough case --  by :user:`Avasam` (4754)

75.5.0

=======

Features
--------

- Removed support for ``SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION``, as it
is deemed prone to errors. (4746)

75.4.0

=======

Features
--------

- Added support for the environment variable
``SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION=true``, allowing users to bypass
the validation of ``pyproject.toml``.
This option should be used only as a last resort when resolving dependency
issues, as it may lead to improper functioning.
Users who enable this setting are responsible for ensuring that ``pyproject.toml``
complies with setuptools requirements. (4611)

.. attention::
  This environment variable was removed in a later version of ``setuptools``.

- Require Python 3.9 or later. (4718)
- Remove dependency on ``importlib_resources``
and the vendored copy of the library.
Instead, ``setuptools`` consistently rely on stdlib's ``importlib.resources``
(available on Python 3.9+). (4718)
- Setuptools' ``bdist_wheel`` implementation no longer produces wheels with
the ``m`` SOABI flag (pymalloc-related).
This flag was removed on Python 3.8+ (see :obj:`sys.abiflags`). (4718)
- Updated vendored packaging version to 24.2. (4740)


Bugfixes
--------

- Merge with pypa/distutils251797602, including fix for dirutil.mkpath handling in pypa/distutils304.

75.3.2

=======

- Fixed version error in changelog.

75.3.1

=======

Bugfixes
--------

- Fix wheel file naming to follow binary distribution specification -- by :user:`di` (4877)

- Check if there is a newline before the terminating quotes of a docstring (4185)
- Fix type annotation spacing between `*` and more complex type variable tuple (4440)

The following changes were not in any previous release:

- Remove parentheses around sole list items (4312)
- Generic function definitions are now formatted more elegantly: parameters are
split over multiple lines first instead of type parameter definitions (4553)

Stable style

- Fix formatting cells in IPython notebooks with magic methods and starting or trailing
empty lines (4484)
- Fix crash when formatting `with` statements containing tuple generators/unpacking
(4538)

Preview style

- Fix/remove string merging changing f-string quotes on f-strings with internal quotes
(4498)
- Collapse multiple empty lines after an import into one (4489)
- Prevent `string_processing` and `wrap_long_dict_values_in_parens` from removing
parentheses around long dictionary values (4377)
- Move `wrap_long_dict_values_in_parens` from the unstable to preview style (4561)

Packaging

- Store license identifier inside the `License-Expression` metadata field, see
[PEP 639](https://peps.python.org/pep-0639/). (#4479)

Performance

- Speed up the `is_fstring_start` function in Black's tokenizer (4541)

Integrations

- If using stdin with `--stdin-filename` set to a force excluded path, stdin won't be
formatted. (4539)

- Black is now officially tested with Python 3.13 and provides Python 3.13
mypyc-compiled wheels. (4436) (4449)
- Black will issue an error when used with Python 3.12.5, due to an upstream memory
safety issue in Python 3.12.5 that can cause Black's AST safety checks to fail. Please
use Python 3.12.6 or Python 3.12.4 instead. (4447)
- Black no longer supports running with Python 3.8 (4452)

Stable style

- Fix crashes involving comments in parenthesised return types or `X | Y` style unions.
(4453)
- Fix skipping Jupyter cells with unknown `%%` magic (4462)

fn(*args: *tuple[*Ts, T]) -> None: pass`) (4440)

Caching

- Fix bug where the cache was shared between runs with and without `--unstable` (4466)

Packaging

- Upgrade version of mypyc used to 1.12 beta (4450) (4449)

Update coverage from 7.6.1 to 7.8.0.

Changelog

7.8.0

--------------------------

- Added a new ``source_dirs`` setting for symmetry with the existing
``source_pkgs`` setting. It's preferable to the existing ``source`` setting,
because you'll get a clear error when directories don't exist. Fixes `issue
1942`_.  Thanks, `Jeremy Fleischman <pull 1943_>`_.

- Fix: the PYTHONSAFEPATH environment variable new in Python 3.11 is properly
supported, closing `issue 1696`_.  Thanks, `Philipp A. <pull 1700_>`_.  This
works properly except for a detail when using the ``coverage`` command on
Windows.  There you can use ``python -m coverage`` instead if you need exact
emulation.

.. _changes_7-7-1:

7.7.1

--------------------------

- A few small tweaks to the sys.monitoring support for Python 3.14.  Please
test!


.. _changes_7-7-0:

7.7.0

--------------------------

- The Coverage object has a new method, :meth:`.Coverage.branch_stats` for
getting simple branch information for a module.  Closes `issue 1888`_.

- The :class:`Coverage constructor<.Coverage>` now has a ``plugins`` parameter
for passing in plugin objects directly, thanks to `Alex Gaynor <pull
1919_>`_.

- Many constant tests in if statements are now recognized as being optimized
away.  For example, previously ``if 13:`` would have been considered a branch
with one path not taken.  Now it is understood as always true and no coverage
is missing.

- The experimental sys.monitoring support now works for branch coverage if you
are using Python 3.14.0 alpha 6 or newer.  This should reduce the overhead
coverage.py imposes on your test suite. Set the environment variable
``COVERAGE_CORE=sysmon`` to try it out.

- Confirmed support for PyPy 3.11. Thanks Michał Górny.

- Fix: some aarch64 distributions were missing (`issue 1927`_).  These are now
building reliably.

.. _issue 1927: https://github.com/nedbat/coveragepy/issues/1927

.. _changes_7-6-11:

7.6.11

---------------------------

- Fix: a memory leak in CTracer has been fixed.  The details are in `issue
1924`_ and `pytest-dev 676`_.  This should reduce the memory footprint for
everyone even if it hadn't caused a problem before.

- We now ship a py3-none-any.whl wheel file.  Thanks, `Russell Keith-Magee
<pull 1914_>`_.

7.6.10

---------------------------

- Fix: some descriptions of missing branches in HTML and LCOV reports were
incorrect when multi-line statements were involved (`issue 1874`_ and `issue
1875`_).  These are now fixed.

- Fix: Python 3.14 `defers evaluation of annotations <pep649_>`_ by moving them
into separate code objects.  That code is rarely executed, so coverage.py
would mark them as missing, as reported in `issue 1908`_.  Now they are
ignored by coverage automatically.

- Fixed an obscure and mysterious problem on PyPy 3.10 seemingly involving
mocks, imports, and trace functions: `issue 1902`_.  To be honest, I don't
understand the problem or the solution, but ``git bisect`` helped find it,
and now it's fixed.

- Docs: re-wrote the :ref:`subprocess` page to put multiprocessing first and to
highlight the correct use of :class:`multiprocessing.Pool
<python:multiprocessing.pool.Pool>`.

.. _changes_7-6-9:

7.6.9

--------------------------

- Fix: `Tomas Uribe fixed <pull 1901_>`_ a performance problem in the XML
report.  Large code bases should produce XML reports much faster now.

.. _pull 1901: https://github.com/nedbat/coveragepy/pull/1901


.. _changes_7-6-8:

7.6.8

--------------------------

- Fix: the LCOV report code assumed that a branch line that took no branches
meant that the entire line was unexecuted.  This isn't true in a few cases:
the line might always raise an exception, or might have been optimized away.
Fixes `issue 1896`_.

- Fix: similarly, the HTML report will now explain that a line that jumps to
none of its expected destinations must have always raised an exception.
Previously, it would say something nonsensical like, "line 4 didn't jump to
line 5 because line 4 was never true, and it didn't jump to line 7 because
line 4 was always true."  This was also shown in `issue 1896`_.

.. _issue 1896: https://github.com/nedbat/coveragepy/issues/1896


.. _changes_7-6-7:

7.6.7

--------------------------

- Fix: ugh, the other assert from 7.6.5 can also be encountered in the wild,
so it's been restored to a conditional.  Sorry for the churn.


.. _changes_7-6-6:

7.6.6

--------------------------

- One of the new asserts from 7.6.5 caused problems in real projects, as
reported in `issue 1891`_.  The assert has been removed.

.. _issue 1891: https://github.com/nedbat/coveragepy/issues/1891


.. _changes_7-6-5:

7.6.5

--------------------------

- Fix: fine-tuned the exact Python version (3.12.6) when exiting from ``with``
statements changed how they traced.  This affected whether people saw the
fix for `issue 1880`_.

- Fix: isolate our code more from mocking in the os module that in rare cases
can cause `bizarre behavior <pytest-cov-666_>`_.

- Refactor: some code unreachable code paths in parser.py were changed to
asserts.  If you encounter any of these, please let me know!

.. _pytest-cov-666: https://github.com/pytest-dev/pytest-cov/issues/666


.. _changes_7-6-4:

7.6.4

--------------------------

- Fix: multi-line ``with`` statements could cause contained branches to be
incorrectly marked as missing (`issue 1880`_).  This is now fixed.

.. _issue 1880: https://github.com/nedbat/coveragepy/issues/1880


.. _changes_7-6-3:

7.6.3

--------------------------

- Fix: nested context managers could incorrectly be analyzed to flag a missing
branch on the last context manager, as described in `issue 1876`_.  This is
now fixed.

- Fix: the missing branch message about not exiting a module had an extra
"didn't," as described in `issue 1873`_.  This is now fixed.

.. _issue 1873: https://github.com/nedbat/coveragepy/issues/1873
.. _issue 1876: https://github.com/nedbat/coveragepy/issues/1876


.. _changes_7-6-2:

7.6.2

--------------------------

- Dropped support for Python 3.8 and PyPy 3.8.

- Fix: a final wildcard match/case clause assigning to a name (``case _ as
value``) was incorrectly marked as a missing branch.  This is now fixed,
closing `issue 1860`_.

- Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution.  Closes `issue 1852`_.

- Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation.  This is now fixed, closing `issue 1836`_, thanks
to `LiuYinCarl and Marco Ricci <pull 1838_>`_.

- Fix: the LCOV report now has correct line numbers (fixing `issue 1846`_) and
better branch descriptions for BRDA records (fixing `issue 1850`_).  There
are other changes to lcov also, including a new configuration option
:ref:`line_checksums <config_lcov_line_checksums>` to control whether line
checksums are included in the lcov report.  The default is false. To keep
checksums set it to true.  All this work is thanks to Zack Weinberg
(`pull 1849`_ and `pull 1851`_).

- Fixed the docs for multi-line regex exclusions, closing `issue 1863`_.

- Fixed a potential crash in the C tracer, closing `issue 1835`_, thanks to
`Jan Kühle <pull 1843_>`_.

Changelog

1.15

We’ve just uploaded mypy 1.15 to the Python Package Index ([PyPI](https://pypi.org/project/mypy/)).
Mypy is a static type checker for Python. This release includes new features, performance
improvements and bug fixes. You can install it as follows:

 python3 -m pip install -U mypy

You can read the full documentation for this release on [Read the Docs](http://mypy.readthedocs.io).

Performance Improvements

Mypy is up to 40% faster in some use cases. This improvement comes largely from tuning the performance
of the garbage collector. Additionally, the release includes several micro-optimizations that may
be impactful for large projects.

PR [18299](https://github.com/python/mypy/pull/18299).

Mypyc Accelerated Mypy Wheels for ARM Linux

For best performance, mypy can be compiled to C extension modules using mypyc. This makes
mypy 3-5x faster than when interpreted with pure Python. We now build and upload mypyc
accelerated mypy wheels for `manylinux_aarch64` to PyPI, making it easy for Linux users on
ARM platforms to realise this speedup -- just `pip install` the latest mypy.

PR [mypy_mypyc-wheels89](https://github.com/mypyc/mypy_mypyc-wheels/pull/89)).

`--strict-bytes`

By default, mypy treats `bytearray` and `memoryview` values as assignable to the `bytes`
type, for historical reasons. Use the `--strict-bytes` flag to disable this
behavior. [PEP 688](https://peps.python.org/pep-0688) specified the removal of this
special case. The flag will be enabled by default in **mypy 2.0**.

Shantanu Jain (PR [13952](https://github.com/python/mypy/pull/13952)).

Improvements to Reachability Analysis and Partial Type Handling in Loops

This change results in mypy better modelling control flow within loops and hence detecting
several previously ignored issues. In some cases, this change may require additional
explicit variable annotations.

PR [18433](https://github.com/python/mypy/pull/18433)).

(Speaking of partial types, remember that we plan to enable `--local-partial-types`
by default in **mypy 2.0**.)

Better Discovery of Configuration Files

Mypy will now walk up the filesystem (up until a repository or file system root) to discover
configuration files. See the
[mypy configuration file documentation](https://mypy.readthedocs.io/en/stable/config_file.html)
for more details.

Better Line Numbers for Decorators and Slice Expressions

Mypy now uses more correct line numbers for decorators and slice expressions. In some cases,
you may have to change the location of a ` type: ignore` comment.

Contributed by Shantanu Jain (PR [18392](https://github.com/python/mypy/pull/18392),
PR [18397](https://github.com/python/mypy/pull/18397)).

Drop Support for Python 3.8

Mypy no longer supports running with Python 3.8, which has reached end-of-life.
When running mypy with Python 3.9+, it is still possible to type check code
that needs to support Python 3.8 with the `--python-version 3.8` argument.
Support for this will be dropped in the first half of 2025!

Contributed by Marc Mueller (PR [17492](https://github.com/python/mypy/pull/17492)).

1.14

We’ve just uploaded mypy 1.14 to the Python Package Index ([PyPI](https://pypi.org/project/mypy/)).
Mypy is a static type checker for Python. This release includes new features and bug fixes.
You can install it as follows:

 python3 -m pip install -U mypy

You can read the full documentation for this release on [Read the Docs](http://mypy.readthedocs.io).

Change to Enum Membership Semantics

As per the updated [typing specification for enums](https://typing.readthedocs.io/en/latest/spec/enums.html#defining-members),
enum members must be left unannotated.

python
class Pet(Enum):
 CAT = 1   Member attribute
 DOG = 2   Member attribute

  New error: Enum members must be left unannotated
 WOLF: int = 3

 species: str   Considered a non-member attribute


In particular, the specification change can result in issues in type stubs (`.pyi` files), since
historically it was common to leave the value absent:

python
In a type stub (.pyi file)

class Pet(Enum):
  Change in semantics: previously considered members,
  now non-member attributes
 CAT: int
 DOG: int

  Mypy will now issue a warning if it detects this
  situation in type stubs:
  > Detected enum "Pet" in a type stub with zero
  > members. There is a chance this is due to a recent
  > change in the semantics of enum membership. If so,
  > use `member = value` to mark an enum member,
  > instead of `member: type`

class Pet(Enum):
  As per the specification, you should now do one of
  the following:
 DOG = 1   Member attribute with value 1 and known type
 WOLF = cast(int, ...)   Member attribute with unknown
                         value but known type
 LION = ...   Member attribute with unknown value and
               unknown type

Shantanu Jain (PR [18068](https://github.com/python/mypy/pull/18068)).

Support for deprecated Decorator (PEP 702)

Mypy can now issue errors or notes when code imports a deprecated feature
explicitly with a `from mod import depr` statement, or uses a deprecated feature
imported otherwise or defined locally. Features are considered deprecated when
decorated with `warnings.deprecated`, as specified in [PEP 702](https://peps.python.org/pep-0702).

You can enable the error code via `--enable-error-code=deprecated` on the mypy
command line or `enable_error_code = deprecated` in the mypy config file.
Use the command line flag `--report-deprecated-as-note` or config file option
`report_deprecated_as_note=True` to turn all such errors into notes.

Deprecation errors will be enabled by default in a future mypy version.

This feature was contributed by Christoph Tyralla.

List of changes:

* Add basic support for PEP 702 (`deprecated`) (Christoph Tyralla, PR [17476](https://github.com/python/mypy/pull/17476))
* Support descriptors with `deprecated` (Christoph Tyralla, PR [18090](https://github.com/python/mypy/pull/18090))
* Make "deprecated" note an error, disabled by default (Valentin Stanciu, PR [18192](https://github.com/python/mypy/pull/18192))
* Consider all possible type positions with `deprecated` (Christoph Tyralla, PR [17926](https://github.com/python/mypy/pull/17926))
* Improve the handling of explicit type annotations in assignment statements with `deprecated` (Christoph Tyralla, PR [17899](https://github.com/python/mypy/pull/17899))

Optionally Analyzing Untyped Modules

Mypy normally doesn't analyze imports from third-party modules (installed using pip, for example)
if there are no stubs or a py.typed marker file. To force mypy to analyze these imports, you
can now use the `--follow-untyped-imports` flag or set the `follow_untyped_imports`
config file option to True. This can be set either in the global section of your mypy config
file, or individually on a per-module basis.

This feature was contributed by Jannick Kremer.

List of changes:

* Implement flag to allow type checking of untyped modules (Jannick Kremer, PR [17712](https://github.com/python/mypy/pull/17712))
* Warn about `--follow-untyped-imports` (Shantanu, PR [18249](https://github.com/python/mypy/pull/18249))

Support New Style Type Variable Defaults (PEP 696)

Mypy now supports type variable defaults using the new syntax described in PEP 696, which
was introduced in Python 3.13. Example:

python
dataclass
class Box[T = int]:   Set default for "T"
 value: T | None = None

reveal_type(Box())                       type is Box[int], since it's the default
reveal_type(Box(value="Hello World!"))   type is Box[str]


This feature was contributed by Marc Mueller (PR [17985](https://github.com/python/mypy/pull/17985)).

Improved For Loop Index Variable Type Narrowing

Mypy now preserves the literal type of for loop index variables, to support `TypedDict`
lookups. Example:

python
from typing import TypedDict

class X(TypedDict):
 hourly: int
 daily: int

def func(x: X) -> int:
 s = 0
 for var in ("hourly", "daily"):
      "Union[Literal['hourly']?, Literal['daily']?]"
     reveal_type(var)

      x[var] no longer triggers a literal-required error
     s += x[var]
 return s


This was contributed by Marc Mueller (PR [18014](https://github.com/python/mypy/pull/18014)).
