6.0.5 (2024-02-01)

Bug fixes

- Upgraded the C-API macros that have been deprecated in Python 3.9

and later removed in 3.13 -- by :user:`iemelyanov`.

*Related issues and pull requests on GitHub:*

:issue:`862`, :issue:`864`, :issue:`868`, :issue:`898`.

- Reverted to using the public argument parsing API

:c:func:`PyArg_ParseTupleAndKeywords` under Python 3.12

-- by :user:`charles-dyfis-net` and :user:`webknjaz`.

The effect is that this change prevents build failures with

clang 16.9.6 and gcc-14 reported in :issue:`926`. It also

fixes a segmentation fault crash caused by passing keyword

arguments to :py:meth:`MultiDict.getall()

<multidict.MultiDict.getall>` discovered by :user:`jonaslb`

and :user:`hroncok` while examining the problem.

*Related issues and pull requests on GitHub:*

:issue:`862`, :issue:`909`, :issue:`926`, :issue:`929`.

- Fixed a ``SystemError: null argument to internal routine`` error on

a ``MultiDict.items().isdisjoint()`` call when using C Extensions.

*Related issues and pull requests on GitHub:*

:issue:`927`.

Improved documentation

- On the `Contributing docs <https://github.com/aio-libs/multidict/blob/master/CHANGES/README.rst>`_ page,

a link to the ``Towncrier philosophy`` has been fixed.

Packaging updates and notes for downstreams

- Stopped marking all files as installable package data

-- by :user:`webknjaz`.

This change helps ``setuptools`` understand that C-headers are

not to be installed under :file:`lib/python3.{x}/site-packages/`.

*Related commits on GitHub:*

:commit:`31e1170`.

- Started publishing pure-python wheels to be installed

as a fallback -- by :user:`webknjaz`.

*Related commits on GitHub:*

:commit:`7ba0e72`.

- Switched from ``setuptools``' legacy backend (``setuptools.build_meta:__legacy__``)

to the modern one (``setuptools.build_meta``) by actually specifying the

the ``[build-system] build-backend`` option in :file:`pyproject.toml`

-- by :user:`Jackenmen`.

*Related issues and pull requests on GitHub:*

:issue:`802`.

- Declared Python 3.12 supported officially in the

distribution package metadata -- by :user:`hugovk`.

*Related issues and pull requests on GitHub:*

:issue:`877`.

Contributor-facing changes

- The test framework has been refactored. In the previous state, the circular

imports reported in :issue:`837` caused the C-extension tests to be skipped.

Now, there is a set of the ``pytest`` fixtures that is set up in a parametrized

manner allowing to have a consistent way of accessing mirrored ``multidict``

implementations across all the tests.

This change also implemented a pair of CLI flags (``--c-extensions`` /

``--no-c-extensions``) that allow to explicitly request deselecting the tests

running against the C-extension.

- Updated the test pins lockfile used in the

``cibuildwheel`` test stage -- by :user:`hoodmane`.

*Related issues and pull requests on GitHub:*

:issue:`827`.

- Added an explicit ``void`` for arguments in C-function signatures

which addresses the following compiler warning:

.. code-block:: console

-- by :user:`hoodmane`

:issue:`828`.

- An experimental Python 3.13 job now runs in the CI

-- :user:`webknjaz`.

*Related issues and pull requests on GitHub:*

:issue:`920`.

- Added test coverage for the :ref:`and <python:and>`, :ref:`or

<python:or>`, :py:obj:`sub <python:object.__sub__>`, and

:py:obj:`xor <python:object.__xor__>` operators in the

:file:`multidict/_multidict_base.py` module. It also covers

:py:data:`NotImplemented` and

":py:class:`~typing.Iterable`-but-not-:py:class:`~typing.Set`"

cases there.

-- by :user:`a5r0n`

*Related issues and pull requests on GitHub:*

:issue:`936`.

- The version of pytest is now capped below 8, when running MyPy

against Python 3.7. This pytest release dropped support for

said runtime.
