astroid's ChangeLog
===================
What's New in astroid 3.0.0?
=============================
Release date: TBA
* Remove support for Python 3.7.
Refs #2137
* Remove ``@cached`` and ``@cachedproperty`` decorator (just use ``@cached_property`` from the stdlib).
Closes #1780
Refs #2140
* Reduce file system access in ``ast_from_file()``.
* Fix incorrect cache keys for inference results, thereby correctly inferring types
for calls instantiating types dynamically.
Closes #1828
Closes pylint-dev/pylint#7464
Closes pylint-dev/pylint#8074
* ``nodes.FunctionDef`` no longer inherits from ``nodes.Lambda``.
This is a breaking change but considered a bug fix as the nodes did not share the same
API and were not interchangeable.
We have tried to minimize the amount of breaking changes caused by this change
but some are unavoidable.
* ``infer_call_result`` now shares the same interface across all implemenations. Namely:
```python
def infer_call_result(
self,
caller: SuccessfulInferenceResult | None,
context: InferenceContext | None = None,
) -> Iterator[InferenceResult]:
```
This is a breaking change for ``nodes.FunctionDef`` where previously ``caller`` had a default of
``None``. Passing ``None`` again will not create a behaviour change.
The breaking change allows us to better type and re-use the method within ``astroid``.
* Improved signature of the ``__init__`` and ``__postinit__`` methods of most nodes.
This includes makes ``lineno``, ``col_offset``, ``end_lineno``, ``end_col_offset`` and ``parent``
required arguments for ``nodes.NodeNG`` and its subclasses.
For most other nodes, arguments of their ``__postinit__`` methods have been made required to better
represent how they would normally be constructed by the standard library ``ast`` module.
The following nodes were changed or updated:
- ``nodes.AnnAssign``
- ``nodes.Arguments``
- ``nodes.Assign``
- ``nodes.AssignAttr``
- ``nodes.AssignName``
- ``nodes.Attribute``
- ``nodes.AugAssign``
- ``nodes.Await``
- ``nodes.BaseContainer``
- ``nodes.BinOp``
- ``nodes.Call``
- ``nodes.ClassDef``
- ``nodes.Compare``
- ``nodes.Comprehension``
- ``nodes.Decorators``
- ``nodes.Delete``
- ``nodes.DelAttr``
- ``nodes.DelName``
- ``nodes.Dict``
- ``nodes.DictComp``
- ``nodes.ExceptHandler``
- ``nodes.Expr``
- ``nodes.For``
- ``nodes.FunctionDef``
- ``nodes.GeneratorExp``
- ``nodes.If``
- ``nodes.IfExp``
- ``nodes.Keyword``
- ``nodes.Lambda``
- ``nodes.ListComp``
- ``nodes.Module``
- ``nodes.Name``
- ``nodes.NodeNG``
- ``nodes.Raise``
- ``nodes.Return``
- ``nodes.SetComp``
- ``nodes.Slice``
- ``nodes.Starred``
- ``objects.Super``, we also added the ``call`` parameter to its ``__init__`` method.
- ``nodes.TryExcept``
- ``nodes.Subscript``
- ``nodes.UnaryOp``
- ``nodes.While``
- ``nodes.Yield``
These changes involve breaking changes to their API but should be considered bug fixes. We
now make arguments required when they are instead of always providing defaults.
* ``nodes.If.self.is_orelse`` has been removed as it was never set correctly and therefore
provided a false value.
* Remove dependency on ``wrapt``.
* Remove dependency on ``lazy_object_proxy``. This includes the removal
of the assosicated ``lazy_import``, ``lazy_descriptor`` and ``proxy_alias`` utility functions.
* ``CallSite._unpack_args`` and ``CallSite._unpack_keywords`` now use ``safe_infer()`` for
better inference and fewer false positives.
Closes pylint-dev/pylint#8544
* Add ``attr.Factory`` to the recognized class attributes for classes decorated with ``attrs``.
Closes pylint-dev/pylint#4341
* ``infer_property()`` now observes the same property-specific workaround as ``infer_functiondef``.
Refs #1490
* Remove unused and / or deprecated constants:
- ``astroid.bases.BOOL_SPECIAL_METHOD``
- ``astroid.bases.BUILTINS``
- ``astroid.const.BUILTINS``
- ``astroid.const.PY38_PLUS``
- ``astroid.const.Load``
- ``astroid.const.Store``
- ``astroid.const.Del``
Refs #2141
* Remove deprecated ``Ellipsis``, ``ExtSlice``, ``Index`` nodes.
Refs #2152
* Remove deprecated ``is_sys_guard`` and ``is_typing_guard`` methods.
Refs #2153
* Remove deprecated ``doc`` attribute for ``Module``, ``ClassDef``, and ``FunctionDef``.
Use the ``doc_node`` attribute instead.
Refs #2154
* Publicize ``NodeNG.repr_name()`` to facilitate finding a node's nice name.
Refs pylint-dev/pylint#8598
What's New in astroid 2.15.5?
=============================
Release date: TBA
* Handle ``objects.Super`` in ``helpers.object_type()``.
Refs pylint-dev/pylint#8554
* Recognize stub ``pyi`` Python files.
Refs pylint-dev/pylint#4987
What's New in astroid 2.15.4?
=============================
Release date: 2023-04-24
* Add visitor function for ``TryStar`` to ``AsStringVisitor`` and
add ``TryStar`` to ``astroid.nodes.ALL_NODE_CLASSES``.
Refs #2142
What's New in astroid 2.15.3?
=============================
Release date: 2023-04-16
* Fix ``infer_call_result()`` crash on methods called ``with_metaclass()``.
Closes #1735
* Suppress ``UserWarning`` when finding module specs.
Closes pylint-dev/pylint#7906
What's New in astroid 2.15.2?
=============================
Release date: 2023-04-03
* Support more possible usages of ``attrs`` decorators.
Closes pylint-dev/pylint#7884
What's New in astroid 2.15.1?
=============================
Release date: 2023-03-26
* Restore behavior of setting a Call as a base for classes created using ``six.with_metaclass()``,
and harden support for using enums as metaclasses in this case.
Reverts #1622
Refs pylint-dev/pylint#5935
Refs pylint-dev/pylint#7506
What's New in astroid 2.15.0?
=============================
Release date: 2023-03-06
* astroid now supports ``TryStar`` nodes from python 3.11 and should be fully compatible with python 3.11.
Closes #2028
* ``Formattedvalue.postinit`` is now keyword only. This is to allow correct typing of the
``Formattedvalue`` class.
Refs #1516
* ``Astroid`` now supports custom import hooks.
Refs pylint-dev/pylint#7306
* ``astroid`` now infers return values from match cases.
Refs pylint-dev/pylint#5288
* ``AstroidManager.clear_cache`` now also clears the inference context cache.
Refs #1780
* ``Astroid`` now retrieves the default values of keyword only arguments and sets them on
``Arguments.kw_defaults``.
* ``Uninferable`` now has the type ``UninferableBase``. This is to facilitate correctly type annotating
code that uses this singleton.
Closes #1680
* Deprecate ``modutils.is_standard_module()``. It will be removed in the next minor release.
Functionality has been replaced by two new functions,
``modutils.is_stdlib_module()`` and ``modutils.module_in_path()``.
Closes #2012
* Fix ``are_exclusive`` function when a walrus operator is used inside ``IfExp.test`` field.
Closes #2022

=============================
Release date: 2022-03-12

and ``nodes.FunctionDef``.
* Accessing the ``doc`` attribute of ``nodes.Module``, ``nodes.ClassDef``, and
``nodes.FunctionDef`` has been deprecated in favour of the ``doc_node`` attribute.
Note: ``doc_node`` is an (optional) ``nodes.Const`` whereas ``doc`` was an (optional) ``str``.
* Passing the ``doc`` argument to the ``__init__`` of ``nodes.Module``, ``nodes.ClassDef``,
and ``nodes.FunctionDef`` has been deprecated in favour of the ``postinit`` ``doc_node`` attribute.
Note: ``doc_node`` is an (optional) ``nodes.Const`` whereas ``doc`` was an (optional) ``str``.

for Python 3.8+.
Closes #1410
* Set ``end_lineno`` and ``end_col_offset`` attributes to ``None`` for all nodes
with PyPy 3.8. PyPy 3.8 assigns these attributes inconsistently which could lead
to unexpected errors. Overwriting them with ``None`` will cause a fallback
to the already supported way of PyPy 3.7.
* Add missing ``shape`` parameter to numpy ``zeros_like``, ``ones_like``,
and ``full_like`` methods.
Closes pylint-dev/pylint#5871
* Only pin ``wrapt`` on the major version.
What's New in astroid 2.10.0?

* Fixed inference of ``self`` in binary operations in which ``self``
is part of a list or tuple.
Closes pylint-dev/pylint#4826
* Fixed builtin inference on `property` calls not calling the `postinit` of the new node, which
resulted in instance arguments missing on these nodes.
* Fixed a crash on ``Super.getattr`` when the attribute was previously uninferable due to a cache
limit size. This limit can be hit when the inheritance pattern of a class (and therefore of the
``__init__`` attribute) is very large.
Closes pylint-dev/pylint#5679
* Include names of keyword-only arguments in ``astroid.scoped_nodes.Lambda.argnames``.
Closes pylint-dev/pylint#5771
* Fixed a crash inferring on a ``NewType`` named with an f-string.
Closes pylint-dev/pylint#5770
* Add support for [attrs v21.3.0](https://github.com/python-attrs/attrs/releases/tag/21.3.0) which
added a new `attrs` module alongside the existing `attr`.
Closes #1330
* Use the ``end_lineno`` attribute for the ``NodeNG.tolineno`` property
when it is available.
Closes #1350
* Add ``is_dataclass`` attribute to ``ClassDef`` nodes.
* Use ``sysconfig`` instead of ``distutils`` to determine the location of
python stdlib files and packages.

Closes #1282
Ref #1103
* Fixed crash with recursion error for inference of class attributes that referenced
the class itself.
Closes pylint-dev/pylint#5408
* Fixed crash when trying to infer ``items()`` on the ``__dict__``
attribute of an imported module.
Closes #1085
* Add optional ``NodeNG.position`` attribute.
Used for block nodes to highlight position of keyword(s) and name
in cases where the AST doesn't provide good enough positional information.
E.g. ``nodes.ClassDef``, ``nodes.FunctionDef``.
* Fix ``ClassDef.fromlineno``. For Python < 3.8 the ``lineno`` attribute includes decorators.
``fromlineno`` should return the line of the ``class`` statement itself.
* Performance improvements. Only run expensive decorator functions when
non-default Deprecation warnings are enabled, eg. during a Pytest run.
Closes #1383
What's New in astroid 2.9.3?

What's New in astroid 2.9.1?
============================
Release date: 2021-12-31
* ``NodeNG.frame()`` and ``NodeNG.statement()`` will start raising ``ParentMissingError``
instead of ``AttributeError`` in astroid 3.0. This behaviour can already be triggered
by passing ``future=True`` to a ``frame()`` or ``statement()`` call.
* Prefer the module loader get_source() method in AstroidBuilder's
module_build() when possible to avoid assumptions about source
code being available on a filesystem. Otherwise the source cannot
be found and application behavior changes when running within an
embedded hermetic interpreter environment (pyoxidizer, etc.).
* Require Python 3.6.2 to use astroid.
* Removed custom ``distutils`` handling for resolving paths to submodules.
Ref #1321
* Restore custom ``distutils`` handling for resolving paths to submodules.
