py-attrs: updated to 21.4.0

21.4.0 (2021-12-29)
-------------------

Changes
^^^^^^^

- Fixed the test suite on PyPy3.8 where ``cloudpickle`` does not work.
- Fixed ``coverage report`` for projects that use ``attrs`` and don't set a ``--source``.


----


21.3.0 (2021-12-28)
-------------------

Backward-incompatible Changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- When using ``@define``, converters are now run by default when setting an attribute on an instance -- additionally to validators.
  I.e. the new default is ``on_setattr=[attrs.setters.convert, attrs.setters.validate]``.

  This is unfortunately a breaking change, but it was an oversight, impossible to raise a ``DeprecationWarning`` about, and it's better to fix it now while the APIs are very fresh with few users.
- ``import attrs`` has finally landed!
  As of this release, you can finally import ``attrs`` using its proper name.

  Not all names from the ``attr`` namespace have been transferred; most notably ``attr.s`` and ``attr.ib`` are missing.
  See ``attrs.define`` and ``attrs.field`` if you haven't seen our next-generation APIs yet.
  A more elaborate explanation can be found `On The Core API Names <https://www.attrs.org/en/latest/names.html>`_

  This feature is at least for one release **provisional**.
  We don't *plan* on changing anything, but such a big change is unlikely to go perfectly on the first strike.

  The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs.
  Please note that we have **not** moved -- or even removed -- anything from ``attr``!

  Please do report any bugs or documentation inconsistencies!


Changes
^^^^^^^

- ``attr.asdict(retain_collection_types=False)`` (default) dumps collection-esque keys as tuples.
- ``__match_args__`` are now generated to support Python 3.10's
  `Structural Pattern Matching <https://docs.python.org/3.10/whatsnew/3.10.html#pep-634-structural-pattern-matching>`_.
  This can be controlled by the ``match_args`` argument to the class decorators on Python 3.10 and later.
  On older versions, it is never added and the argument is ignored.
- If the class-level *on_setattr* is set to ``attrs.setters.validate`` (default in ``@define`` and ``@mutable``) but no field defines a validator, pretend that it's not set.
- The generated ``__repr__`` is significantly faster on Pythons with f-strings.
- Attributes transformed via ``field_transformer`` are wrapped with ``AttrsClass`` again.
- Generated source code is now cached more efficiently for identical classes.
- Added ``attrs.converters.to_bool()``.
- ``attrs.resolve_types()`` now resolves types of subclasses after the parents are resolved.
- Added new validators: ``lt(val)`` (< val), ``le(va)`` (≤ val), ``ge(val)`` (≥ val), ``gt(val)`` (> val), and ``maxlen(n)``.
- ``attrs`` classes are now fully compatible with `cloudpickle <https://github.com/cloudpipe/cloudpickle>`_ (no need to disable ``repr`` anymore).
- Added new context manager ``attrs.validators.disabled()`` and functions ``attrs.validators.(set|get)_disabled()``.
  They deprecate ``attrs.(set|get)_run_validators()``.
  All functions are interoperable and modify the same internal state.
  They are not – and never were – thread-safe, though.
- ``attrs.validators.matches_re()`` now accepts pre-compiled regular expressions in addition to pattern strings.



21.2.0 (2021-05-07)
-------------------

Backward-incompatible Changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- We had to revert the recursive feature for ``attr.evolve()`` because it broke some use-cases -- sorry!
- Python 3.4 is now blocked using packaging metadata because ``attrs`` can't be imported on it anymore.
  To ensure that 3.4 users can keep installing  ``attrs`` easily, we will `yank <https://pypi.org/help/#yanked>`_ 21.1.0 from PyPI.
  This has **no** consequences if you pin ``attrs`` to 21.1.0.



21.1.0 (2021-05-06)
-------------------

Deprecations
^^^^^^^^^^^^

- The long-awaited, much-talked-about, little-delivered ``import attrs`` is finally upon us!

  Since the NG APIs have now been proclaimed stable, the **next** release of ``attrs`` will allow you to actually ``import attrs``.
  We're taking this opportunity to replace some defaults in our APIs that made sense in 2015, but don't in 2021.

  So please, if you have any pet peeves about defaults in ``attrs``'s APIs, *now* is the time to air your grievances in 487!
  We're not gonna get such a chance for a second time, without breaking our backward-compatibility guarantees, or long deprecation cycles.
  Therefore, speak now or forever hold you peace!
- The *cmp* argument to ``attr.s()`` and `attr.ib()` has been **undeprecated**
  It will continue to be supported as syntactic sugar to set *eq* and *order* in one go.

  I'm terribly sorry for the hassle around this argument!
  The reason we're bringing it back is it's usefulness regarding customization of equality/ordering.

  The ``cmp`` attribute and argument on ``attr.Attribute`` remains deprecated and will be removed later this year.


Changes
^^^^^^^

- It's now possible to customize the behavior of ``eq`` and ``order`` by passing in a callable.
- The instant favorite next-generation APIs are not provisional anymore!

  They are also officially supported by Mypy as of their `0.800 release <https://mypy-lang.blogspot.com/2021/01/mypy-0800-released.html>`_.

  We hope the next release will already contain an (additional) importable package called ``attrs``.
- If an attribute defines a converter, the type of its parameter is used as type annotation for its corresponding ``__init__`` parameter.

  If an ``attr.converters.pipe`` is used, the first one's is used.
- Fixed the creation of an extra slot for an ``attr.ib`` when the parent class already has a slot with the same name.
- ``__attrs__init__()`` will now be injected if ``init=False``, or if ``auto_detect=True`` and a user-defined ``__init__()`` exists.

  This enables users to do "pre-init" work in their ``__init__()`` (such as ``super().__init__()``).

  ``__init__()`` can then delegate constructor argument processing to ``self.__attrs_init__(*args, **kwargs)``.
- ``bool(attr.NOTHING)`` is now ``False``.
- It's now possible to use ``super()`` inside of properties of slotted classes.
- Allow for a ``__attrs_pre_init__()`` method that -- if defined -- will get called at the beginning of the ``attrs``-generated ``__init__()`` method.
- Added forgotten ``attr.Attribute.evolve()`` to type stubs.
- ``attrs.evolve()`` now works recursively with nested ``attrs`` classes.
- Python 3.10 is now officially supported.
- ``attr.resolve_types()`` now takes an optional *attrib* argument to work inside a ``field_transformer``.
- ``ClassVar``\ s are now also detected if they come from `typing-extensions <https://pypi.org/project/typing-extensions/>`_.
- To make it easier to customize attribute comparison, we have added the ``attr.cmp_with()`` helper.

  See the `new docs on comparison <https://www.attrs.org/en/stable/comparison.html>`_ for more details.
- Added **provisional** support for static typing in ``pyright`` via the `dataclass_transforms specification <https://github.com/microsoft/pyright/blob/main/specs/dataclass_transforms.md>`_.
  Both the ``pyright`` specification and ``attrs`` implementation may change in future versions of both projects.
