```
### 2.13.1
```
============================
Release date: 2022-03-26
* Fix a regression in 2.13.0 where ``used-before-assignment`` was emitted for
the usage of a nonlocal in a try block.
Fixes 5965
* Avoid emitting ``raising-bad-type`` when there is inference ambiguity on
the variable being raised.
Closes 2793
* Loosen TypeVar default name pattern a bit to allow names with multiple uppercase
characters. E.g. ``HVACModeT`` or ``IPAddressT``.
Closes 5981
* Fixed false positive for ``unused-argument`` when a ``nonlocal`` name is used
in a nested function that is returned without being called by its parent.
Closes 5187
* Fix program crash for ``modified_iterating-list/set/dict`` when the list/dict/set
being iterated through is a function call.
Closes 5969
* Don't emit ``broken-noreturn`` and ``broken-collections-callable`` errors

```
### 2.13.0
```
============================
Release date: 2022-03-24
* Add missing dunder methods to ``unexpected-special-method-signature`` check.
* No longer emit ``no-member`` in for loops that reference ``self`` if the binary operation that
started the for loop uses a ``self`` that is encapsulated in tuples or lists.
Ref PyCQA/astroid1360
Closes 4826
* Output better error message if unsupported file formats are used with ``pyreverse``.
Closes 5950
* Fix pyreverse diagrams type hinting for classmethods and staticmethods.
* Fix pyreverse diagrams type hinting for methods returning None.
* Fix matching ``--notes`` options that end in a non-word character.
Closes 5840
* Updated the position of messages for class and function defintions to no longer cover
the complete definition. Only the ``def`` or ``class`` + the name of the class/function
are covered.
Closes 5466
* ``using-f-string-in-unsupported-version`` and ``using-final-decorator-in-unsupported-version`` msgids
were renamed from ``W1601`` and ``W1602`` to ``W2601`` and ``W2602``. Disabling using these msgids will break.
This is done in order to restore consistency with the already existing msgids for ``apply-builtin`` and
``basestring-builtin`` from the now deleted python 3K+ checker. There is now a check that we're not using
existing msgids or symbols from deleted checkers.
Closes 5729
* The line numbering for messages related to function arguments is now more accurate. This can
require some message disables to be relocated to updated positions.
* Add ``--recursive`` option to allow recursive discovery of all modules and packages in subtree. Running pylint with
``--recursive=y`` option will check all discovered ``.py`` files and packages found inside subtree of directory provided
as parameter to pylint.
Closes 352
* Add ``modified-iterating-list``, ``modified-iterating-dict`` and ``modified-iterating-set``,
emitted when items are added to or removed from respectively a list, dictionary or
set being iterated through.
Closes 5348
* Fix false-negative for ``assignment-from-none`` checker using list.sort() method.
closes 5722
* New extension ``import-private-name``: indicate imports of external private packages
and objects (prefixed with ``_``). It can be loaded using ``load-plugins=pylint.extensions.private_import``.
Closes 5463
* Fixed crash from ``arguments-differ`` and ``arguments-renamed`` when methods were
defined outside the top level of a class.
Closes 5648
* Removed the deprecated ``check_docs`` extension. You can use the ``docparams`` checker
to get the checks previously included in ``check_docs``.
Closes 5322
* Added a ``testutil`` extra require to the packaging, as ``gitpython`` should not be a dependency
all the time but is still required to use the primer helper code in ``pylint.testutil``. You can
install it with ``pip install pylint[testutil]``.
Closes 5486
* Reinstated checks from the python3 checker that are still useful for python 3
(``eq-without-hash``). This is now in the ``pylint.extensions.eq_without_hash`` optional
extension.
Closes 5025
* Fixed an issue where ``ungrouped-imports`` could not be disabled without raising
``useless-suppression``.
Ref 2366
* Added several checkers to deal with unicode security issues
(see `Trojan Sources <https://trojansource.codes/>`_ and
`PEP 672 <https://www.python.org/dev/peps/pep-0672/>`_ for details) that also
concern the readability of the code. In detail the following checks were added:
* ``bad-file-encoding`` checks that the file is encoded in UTF-8 as suggested by
`PEP8 <https://www.python.org/dev/peps/pep-0008/#id20>`_.
UTF-16 and UTF-32 are `not supported by Python <https://bugs.python.org/issue1503789>`_
at the moment. If this ever changes
``invalid-unicode-codec`` checks that they aren't used, to allow for backwards
compatibility.
* ``bidirectional-unicode`` checks for bidirectional unicode characters that
could make code execution different than what the user expects.
* ``invalid-character-backspace``, ``invalid-character-carriage-return``,
``invalid-character-sub``, ``invalid-character-esc``,
``invalid-character-zero-width-space`` and ``invalid-character-nul``
to check for possibly harmful unescaped characters.
Closes 5281
* Use the ``tomli`` package instead of ``toml`` to parse ``.toml`` files.
Closes 5885
* Fix false positive - Allow unpacking of ``self`` in a subclass of ``typing.NamedTuple``.
Closes 5312
* Fixed false negative ``unpacking-non-sequence`` when value is an empty list.
Closes 5707
* Better warning messages for useless else or elif when a function returns early.
Closes 5614
* Fixed false positive ``consider-using-dict-comprehension`` when creating a dict
using a list of tuples where key AND value vary depending on the same condition.
Closes 5588
* Fixed false positive for ``global-variable-undefined`` when ``global`` is used with a class name
Closes 3088
* Fixed false positive for ``unused-variable`` when a ``nonlocal`` name is assigned as part of a multi-name assignment.
Closes 3781
* Fixed a crash in ``unspecified-encoding`` checker when providing ``None``
to the ``mode`` argument of an ``open()`` call.
Closes 5731
* Fixed a crash involving a ``NewType`` named with an f-string.
Closes 5770
Ref PyCQA/astroid1400
* Improved ``bad-open-mode`` message when providing ``None`` to the ``mode``
argument of an ``open()`` call.
Closes 5733
* Added ``lru-cache-decorating-method`` checker with checks for the use of ``functools.lru_cache``
on class methods. This is unrecommended as it creates memory leaks by never letting the instance
getting garbage collected.
Closes 5670
* Fixed crash with recursion error for inference of class attributes that referenced
the class itself.
Closes 5408
Ref PyCQA/astroid1392
* Fixed false positive for ``unused-argument`` when a method overridden in a subclass
does nothing with the value of a keyword-only argument.
Closes 5771
Ref PyCQA/astroid1382
* The issue template for crashes is now created for crashes which were previously not covered
by this mechanism.
Closes 5668
* Rewrote checker for ``non-ascii-name``.
It now ensures __all__ Python names are ASCII and also properly
checks the names of imports (``non-ascii-module-import``) as
well as file names (``non-ascii-file-name``) and emits their respective new warnings.
Non ASCII characters could be homoglyphs (look alike characters) and hard to
enter on a non specialized keyboard.
See `Confusable Characters in PEP 672 <https://www.python.org/dev/peps/pep-0672/#confusable-characters-in-identifiers>`_
* When run in parallel mode ``pylint`` now pickles the data passed to subprocesses with
the ``dill`` package. The ``dill`` package has therefore been added as a dependency.
* An astroid issue where symlinks were not being taken into account
was fixed
Closes 1470
Closes 3499
Closes 4302
Closes 4798
Closes 5081
* Fix a crash in ``unused-private-member`` checker when analyzing code using
``type(self)`` in bound methods.
Closes 5569
* Optimize parsing of long lines when ``missing-final-newline`` is enabled.
Closes 5724
* Fix false positives for ``used-before-assignment`` from using named
expressions in a ternary operator test and using that expression as
a call argument.
Closes 5177, 5212
* Fix false positive for ``undefined-variable`` when ``namedtuple`` class
attributes are used as return annotations.
Closes 5568
* Fix false negative for ``undefined-variable`` and related variable messages
when the same undefined variable is used as a type annotation and is
accessed multiple times, or is used as a default argument to a function.
Closes 5399
* Pyreverse - add output in mermaidjs format
* Emit ``used-before-assignment`` instead of ``undefined-variable`` when attempting
to access unused type annotations.
Closes 5713
* Added confidence level ``CONTROL_FLOW`` for warnings relying on assumptions
about control flow.
* ``used-before-assignment`` now considers that assignments in a try block
may not have occurred when the except or finally blocks are executed.
Closes 85, 2615
* Fixed false negative for ``used-before-assignment`` when a conditional
or context manager intervened before the try statement that suggested
it might fail.
Closes 4045
* Fixed false negative for ``used-before-assignment`` in finally blocks
if an except handler did not define the assignment that might have failed
in the try block.
* Fixed extremely long processing of long lines with comma's.
Closes 5483
* Fixed crash on properties and inherited class methods when comparing them for
equality against an empty dict.
Closes 5646
* Fixed a false positive for ``assigning-non-slot`` when the slotted class
defined ``__setattr__``.
Closes 3793
* Fixed a false positive for ``invalid-class-object`` when the object
being assigned to the ``__class__`` attribute is uninferable.
* Fixed false positive for ``used-before-assignment`` with self-referential type
annotation in conditional statements within class methods.
Closes 5499
* Add checker ``redefined-slots-in-subclass``: Emitted when a slot is redefined in a subclass.
Closes 5617
* Fixed false positive for ``global-variable-not-assigned`` when the ``del`` statement is used
Closes 5333
* By default, pylint does no longer take files starting with ``.`` into account. Those are
considered `emacs file locks`. See
https://www.gnu.org/software/emacs/manual/html_node/elisp/File-Locks.html.
This behavior can be reverted by redefining the ``ignore-patterns`` option.
Closes 367
* Fixed a false positive for ``used-before-assignment`` when a named expression
appears as the first value in a container.
Closes 5112
* ``used-before-assignment`` now assumes that assignments in except blocks
may not have occurred and warns accordingly.
Closes 4761
* When evaluating statements after an except block, ``used-before-assignment``
assumes that assignments in the except blocks took place if the
corresponding try block contained a return statement.
Closes 5500
* Fixed a false negative for ``used-before-assignment`` when some but not all
except handlers defined a name relied upon after an except block when the
corresponding try block contained a return statement.
Closes 5524
* When evaluating statements in the ``else`` clause of a loop, ``used-before-assignment``
assumes that assignments in the except blocks took place if the
except handlers constituted the only ways for the loop to finish without
breaking early.
Closes 5683
* ``used-before-assignment`` now checks names in try blocks.
* Fixed false positive with ``used-before-assignment`` for assignment expressions
in lambda statements.
Closes 5360, 3877
* Fixed a false positive (affecting unreleased development) for
``used-before-assignment`` involving homonyms between filtered comprehensions
and assignments in except blocks.
Closes 5586
* Fixed crash with slots assignments and annotated assignments.
Closes 5479
* Fixed crash on list comprehensions that used ``type`` as inner variable name.
Closes 5461
* Fixed crash in ``use-maxsplit-arg`` checker when providing the ``sep`` argument
to ``str.split()`` by keyword.
Closes 5737
* Fix false positive for ``unused-variable`` for a comprehension variable matching
an outer scope type annotation.
Closes 5326
* Fix false negative for ``undefined-variable`` for a variable used multiple times
in a comprehension matching an unused outer scope type annotation.
Closes 5654
* Some files in ``pylint.testutils`` were deprecated. In the future imports should be done from the
``pylint.testutils.functional`` namespace directly.
* Fixed false positives for ``no-value-for-parameter`` with variadic
positional arguments.
Closes 5416
* ``safe_infer`` no longer makes an inference when given two function
definitions with differing numbers of arguments.
Closes 3675
* Fix ``comparison-with-callable`` false positive for callables that raise, such
as typing constants.
Closes 5557
* Fixed a crash on ``__init__`` nodes 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 5679
* Fix false positive for ``used-before-assignment`` from a class definition
nested under a function subclassing a class defined outside the function.
Closes 4590
* Fix ``unnecessary_dict_index_lookup`` false positive when deleting a dictionary's entry.
Closes 4716
* Fix false positive for ``used-before-assignment`` when an except handler
shares a name with a test in a filtered comprehension.
Closes 5817
* Fix crash in ``unnecessary-dict-index-lookup`` checker if the output of
``items()`` is assigned to a 1-tuple.
Closes 5504
* When invoking ``pylint``, ``epylint``, ``symilar`` or ``pyreverse`` by importing them in a python file
you can now pass an ``argv`` keyword besides patching ``sys.argv``.
Closes 5320
* The ``PyLinter`` class will now be initialized with a ``TextReporter``
as its reporter if none is provided.
* Fix ``super-init-not-called`` when parent or ``self`` is a ``Protocol``
Closes 4790
* Fix false positive ``not-callable`` with attributes that alias ``NamedTuple``
Partially closes 1730
* Emit ``redefined-outer-name`` when a nested except handler shadows an outer one.
Closes 4434
Closes 5370
* Fix false positive ``super-init-not-called`` for classes that inherit their ``init`` from
a parent.
Closes 4941
* ``encoding`` can now be supplied as a positional argument to calls that open
files without triggering ``unspecified-encoding``.
Closes 5638
* Fatal errors now emit a score of 0.0 regardless of whether the linted module
contained any statements
Closes 5451
* ``fatal`` was added to the variables permitted in score evaluation expressions.
* The default score evaluation now uses a floor of 0.
Closes 2399
* Fix false negative for ``consider-iterating-dictionary`` during membership checks encapsulated in iterables
or ``not in`` checks
Closes 5323
* Fixed crash on uninferable decorators on Python 3.6 and 3.7
* Add checker ``unnecessary-ellipsis``: Emitted when the ellipsis constant is used unnecessarily.
Closes 5460
* Disable checker ``bad-docstring-quotes`` for Python <= 3.7, because in these versions the line
numbers for decorated functions and classes are not reliable which interferes with the checker.
Closes 3077
* Fixed incorrect classification of Numpy-style docstring as Google-style docstring for
docstrings with property setter documentation.
Docstring classification is now based on the highest amount of matched sections instead
of the order in which the docstring styles were tried.
* Fixed detection of ``arguments-differ`` when superclass static
methods lacked a ``staticmethod`` decorator.
Closes 5371
* ``TypingChecker``
* Added new check ``broken-noreturn`` to detect broken uses of ``typing.NoReturn``
if ``py-version`` is set to Python ``3.7.1`` or below.
https://bugs.python.org/issue34921
* Added new check ``broken-collections-callable`` to detect broken uses of ``collections.abc.Callable``
if ``py-version`` is set to Python ``3.9.1`` or below.
https://bugs.python.org/issue42965
* The ``testutils`` for unittests now accept ``end_lineno`` and ``end_column``. Tests
without these will trigger a ``DeprecationWarning``.
* ``arguments-differ`` will no longer complain about method redefinitions with extra parameters
that have default values.
Closes 1556, 5338
* Fixed false positive ``unexpected-keyword-arg`` for decorators.
Closes 258
* Importing the deprecated stdlib module ``xml.etree.cElementTree`` now emits ``deprecated_module``.
Closes 5862
* Disables for ``deprecated-module`` and similar warnings for stdlib features deprecated
in newer versions of Python no longer raise ``useless-suppression`` when linting with
older Python interpreters where those features are not yet deprecated.
* Importing the deprecated stdlib module ``distutils`` now emits ``deprecated_module`` on Python 3.10+.
* ``missing-raises-doc`` will now check the class hierarchy of the raised exceptions
.. code-block:: python
def my_function()
"""My function.
Raises:
Exception: if something fails
"""
raise ValueError
Closes 4955
* Allow disabling ``duplicate-code`` with a disable comment when running through
pylint.
Closes 214
* Improve ``invalid-name`` check for ``TypeVar`` names.
The accepted pattern can be customized with ``--typevar-rgx``.
Closes 3401
* Added new checker ``typevar-name-missing-variance``. Emitted when a covariant
or contravariant ``TypeVar`` does not end with ``_co`` or ``_contra`` respectively or
when a ``TypeVar`` is not either but has a suffix.
* Allow usage of mccabe 0.7.x release
Closes 5878
* Fix ``unused-private-member`` false positive when accessing private methods through ``property``.
Closes 4756

Only the ``def`` or ``class`` + the name of the class/function are covered. Closes 5466 * ``using-f-string-in-unsupported-version`` and ``using-final-decorator-in-unsupported-version`` msgids were renamed from ``W1601`` and ``W1602`` to ``W2601`` and ``W2602``. Disabling using these msgids will break. This is done in order to restore consistency with the already existing msgids for ``apply-builtin`` and ``basestring-builtin`` from the now deleted python 3K+ checker. There is now a check that we're not using existing msgids or symbols from deleted checkers. Closes 5729 * The line numbering for messages related to function arguments is now more accurate. This can require some message disables to be relocated to updated positions. * Add ``--recursive`` option to allow recursive discovery of all modules and packages in subtree. Running pylint with ``--recursive=y`` option will check all discovered ``.py`` files and packages found inside subtree of directory provided as parameter to pylint. Closes 352 * Add ``modified-iterating-list``, ``modified-iterating-dict`` and ``modified-iterating-set``, emitted when items are added to or removed from respectively a list, dictionary or set being iterated through. Closes 5348 * Fix false-negative for ``assignment-from-none`` checker using list.sort() method. closes 5722 * New extension ``import-private-name``: indicate imports of external private packages and objects (prefixed with ``_``). It can be loaded using ``load-plugins=pylint.extensions.private_import``. Closes 5463 * Fixed crash from ``arguments-differ`` and ``arguments-renamed`` when methods were defined outside the top level of a class. Closes 5648 * Removed the deprecated ``check_docs`` extension. You can use the ``docparams`` checker to get the checks previously included in ``check_docs``. Closes 5322 * Added a ``testutil`` extra require to the packaging, as ``gitpython`` should not be a dependency all the time but is still required to use the primer helper code in ``pylint.testutil``. You can install it with ``pip install pylint[testutil]``. Closes 5486 * Reinstated checks from the python3 checker that are still useful for python 3 (``eq-without-hash``). This is now in the ``pylint.extensions.eq_without_hash`` optional extension. Closes 5025 * Fixed an issue where ``ungrouped-imports`` could not be disabled without raising ``useless-suppression``. Ref 2366 * Added several checkers to deal with unicode security issues (see `Trojan Sources <https://trojansource.codes/>`_ and `PEP 672 <https://www.python.org/dev/peps/pep-0672/>`_ for details) that also concern the readability of the code. In detail the following checks were added: * ``bad-file-encoding`` checks that the file is encoded in UTF-8 as suggested by `PEP8 <https://www.python.org/dev/peps/pep-0008/#id20>`_. UTF-16 and UTF-32 are `not supported by Python <https://bugs.python.org/issue1503789>`_ at the moment. If this ever changes ``invalid-unicode-codec`` checks that they aren't used, to allow for backwards compatibility. * ``bidirectional-unicode`` checks for bidirectional unicode characters that could make code execution different than what the user expects. * ``invalid-character-backspace``, ``invalid-character-carriage-return``, ``invalid-character-sub``, ``invalid-character-esc``, ``invalid-character-zero-width-space`` and ``invalid-character-nul`` to check for possibly harmful unescaped characters. Closes 5281 * Use the ``tomli`` package instead of ``toml`` to parse ``.toml`` files. Closes 5885 * Fix false positive - Allow unpacking of ``self`` in a subclass of ``typing.NamedTuple``. Closes 5312 * Fixed false negative ``unpacking-non-sequence`` when value is an empty list. Closes 5707 * Better warning messages for useless else or elif when a function returns early. Closes 5614 * Fixed false positive ``consider-using-dict-comprehension`` when creating a dict using a list of tuples where key AND value vary depending on the same condition. Closes 5588 * Fixed false positive for ``global-variable-undefined`` when ``global`` is used with a class name Closes 3088 * Fixed false positive for ``unused-variable`` when a ``nonlocal`` name is assigned as part of a multi-name assignment. Closes 3781 * Fixed a crash in ``unspecified-encoding`` checker when providing ``None`` to the ``mode`` argument of an ``open()`` call. Closes 5731 * Fixed a crash involving a ``NewType`` named with an f-string. Closes 5770 Ref PyCQA/astroid1400 * Improved ``bad-open-mode`` message when providing ``None`` to the ``mode`` argument of an ``open()`` call. Closes 5733 * Added ``lru-cache-decorating-method`` checker with checks for the use of ``functools.lru_cache`` on class methods. This is unrecommended as it creates memory leaks by never letting the instance getting garbage collected. Closes 5670 * Fixed crash with recursion error for inference of class attributes that referenced the class itself. Closes 5408 Ref PyCQA/astroid1392 * Fixed false positive for ``unused-argument`` when a method overridden in a subclass does nothing with the value of a keyword-only argument. Closes 5771 Ref PyCQA/astroid1382 * The issue template for crashes is now created for crashes which were previously not covered by this mechanism. Closes 5668 * Rewrote checker for ``non-ascii-name``. It now ensures __all__ Python names are ASCII and also properly checks the names of imports (``non-ascii-module-import``) as well as file names (``non-ascii-file-name``) and emits their respective new warnings. Non ASCII characters could be homoglyphs (look alike characters) and hard to enter on a non specialized keyboard. See `Confusable Characters in PEP 672 <https://www.python.org/dev/peps/pep-0672/#confusable-characters-in-identifiers>`_ * When run in parallel mode ``pylint`` now pickles the data passed to subprocesses with the ``dill`` package. The ``dill`` package has therefore been added as a dependency. * An astroid issue where symlinks were not being taken into account was fixed Closes 1470 Closes 3499 Closes 4302 Closes 4798 Closes 5081 * Fix a crash in ``unused-private-member`` checker when analyzing code using ``type(self)`` in bound methods. Closes 5569 * Optimize parsing of long lines when ``missing-final-newline`` is enabled. Closes 5724 * Fix false positives for ``used-before-assignment`` from using named expressions in a ternary operator test and using that expression as a call argument. Closes 5177, 5212 * Fix false positive for ``undefined-variable`` when ``namedtuple`` class attributes are used as return annotations. Closes 5568 * Fix false negative for ``undefined-variable`` and related variable messages when the same undefined variable is used as a type annotation and is accessed multiple times, or is used as a default argument to a function. Closes 5399 * Pyreverse - add output in mermaidjs format * Emit ``used-before-assignment`` instead of ``undefined-variable`` when attempting to access unused type annotations. Closes 5713 * Added confidence level ``CONTROL_FLOW`` for warnings relying on assumptions about control flow. * ``used-before-assignment`` now considers that assignments in a try block may not have occurred when the except or finally blocks are executed. Closes 85, 2615 * Fixed false negative for ``used-before-assignment`` when a conditional or context manager intervened before the try statement that suggested it might fail. Closes 4045 * Fixed false negative for ``used-before-assignment`` in finally blocks if an except handler did not define the assignment that might have failed in the try block. * Fixed extremely long processing of long lines with comma's. Closes 5483 * Fixed crash on properties and inherited class methods when comparing them for equality against an empty dict. Closes 5646 * Fixed a false positive for ``assigning-non-slot`` when the slotted class defined ``__setattr__``. Closes 3793 * Fixed a false positive for ``invalid-class-object`` when the object being assigned to the ``__class__`` attribute is uninferable. * Fixed false positive for ``used-before-assignment`` with self-referential type annotation in conditional statements within class methods. Closes 5499 * Add checker ``redefined-slots-in-subclass``: Emitted when a slot is redefined in a subclass. Closes 5617 * Fixed false positive for ``global-variable-not-assigned`` when the ``del`` statement is used Closes 5333 * By default, pylint does no longer take files starting with ``.`` into account. Those are considered `emacs file locks`. See https://www.gnu.org/software/emacs/manual/html_node/elisp/File-Locks.html. This behavior can be reverted by redefining the ``ignore-patterns`` option. Closes 367 * Fixed a false positive for ``used-before-assignment`` when a named expression appears as the first value in a container. Closes 5112 * ``used-before-assignment`` now assumes that assignments in except blocks may not have occurred and warns accordingly. Closes 4761 * When evaluating statements after an except block, ``used-before-assignment`` assumes that assignments in the except blocks took place if the corresponding try block contained a return statement. Closes 5500 * Fixed a false negative for ``used-before-assignment`` when some but not all except handlers defined a name relied upon after an except block when the corresponding try block contained a return statement. Closes 5524 * When evaluating statements in the ``else`` clause of a loop, ``used-before-assignment`` assumes that assignments in the except blocks took place if the except handlers constituted the only ways for the loop to finish without breaking early. Closes 5683 * ``used-before-assignment`` now checks names in try blocks. * Fixed false positive with ``used-before-assignment`` for assignment expressions in lambda statements. Closes 5360, 3877 * Fixed a false positive (affecting unreleased development) for ``used-before-assignment`` involving homonyms between filtered comprehensions and assignments in except blocks. Closes 5586 * Fixed crash with slots assignments and annotated assignments. Closes 5479 * Fixed crash on list comprehensions that used ``type`` as inner variable name. Closes 5461 * Fixed crash in ``use-maxsplit-arg`` checker when providing the ``sep`` argument to ``str.split()`` by keyword. Closes 5737 * Fix false positive for ``unused-variable`` for a comprehension variable matching an outer scope type annotation. Closes 5326 * Fix false negative for ``undefined-variable`` for a variable used multiple times in a comprehension matching an unused outer scope type annotation. Closes 5654 * Some files in ``pylint.testutils`` were deprecated. In the future imports should be done from the ``pylint.testutils.functional`` namespace directly. * Fixed false positives for ``no-value-for-parameter`` with variadic positional arguments. Closes 5416 * ``safe_infer`` no longer makes an inference when given two function definitions with differing numbers of arguments. Closes 3675 * Fix ``comparison-with-callable`` false positive for callables that raise, such as typing constants. Closes 5557 * Fixed a crash on ``__init__`` nodes 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 5679 * Fix false positive for ``used-before-assignment`` from a class definition nested under a function subclassing a class defined outside the function. Closes 4590 * Fix ``unnecessary_dict_index_lookup`` false positive when deleting a dictionary's entry. Closes 4716 * Fix false positive for ``used-before-assignment`` when an except handler shares a name with a test in a filtered comprehension. Closes 5817 * Fix crash in ``unnecessary-dict-index-lookup`` checker if the output of ``items()`` is assigned to a 1-tuple. Closes 5504 * When invoking ``pylint``, ``epylint``, ``symilar`` or ``pyreverse`` by importing them in a python file you can now pass an ``argv`` keyword besides patching ``sys.argv``. Closes 5320 * The ``PyLinter`` class will now be initialized with a ``TextReporter`` as its reporter if none is provided. * Fix ``super-init-not-called`` when parent or ``self`` is a ``Protocol`` Closes 4790 * Fix false positive ``not-callable`` with attributes that alias ``NamedTuple`` Partially closes 1730 * Emit ``redefined-outer-name`` when a nested except handler shadows an outer one. Closes 4434 Closes 5370 * Fix false positive ``super-init-not-called`` for classes that inherit their ``init`` from a parent. Closes 4941 * ``encoding`` can now be supplied as a positional argument to calls that open files without triggering ``unspecified-encoding``. Closes 5638 * Fatal errors now emit a score of 0.0 regardless of whether the linted module contained any statements Closes 5451 * ``fatal`` was added to the variables permitted in score evaluation expressions. * The default score evaluation now uses a floor of 0. Closes 2399 * Fix false negative for ``consider-iterating-dictionary`` during membership checks encapsulated in iterables or ``not in`` checks Closes 5323 * Fixed crash on uninferable decorators on Python 3.6 and 3.7 * Add checker ``unnecessary-ellipsis``: Emitted when the ellipsis constant is used unnecessarily. Closes 5460 * Disable checker ``bad-docstring-quotes`` for Python <= 3.7, because in these versions the line numbers for decorated functions and classes are not reliable which interferes with the checker. Closes 3077 * Fixed incorrect classification of Numpy-style docstring as Google-style docstring for docstrings with property setter documentation. Docstring classification is now based on the highest amount of matched sections instead of the order in which the docstring styles were tried. * Fixed detection of ``arguments-differ`` when superclass static methods lacked a ``staticmethod`` decorator. Closes 5371 * ``TypingChecker`` * Added new check ``broken-noreturn`` to detect broken uses of ``typing.NoReturn`` if ``py-version`` is set to Python ``3.7.1`` or below. https://bugs.python.org/issue34921 * Added new check ``broken-collections-callable`` to detect broken uses of ``collections.abc.Callable`` if ``py-version`` is set to Python ``3.9.1`` or below. https://bugs.python.org/issue42965 * The ``testutils`` for unittests now accept ``end_lineno`` and ``end_column``. Tests without these will trigger a ``DeprecationWarning``. * ``arguments-differ`` will no longer complain about method redefinitions with extra parameters that have default values. Closes 1556, 5338 * Fixed false positive ``unexpected-keyword-arg`` for decorators. Closes 258 * Importing the deprecated stdlib module ``xml.etree.cElementTree`` now emits ``deprecated_module``. Closes 5862 * Disables for ``deprecated-module`` and similar warnings for stdlib features deprecated in newer versions of Python no longer raise ``useless-suppression`` when linting with older Python interpreters where those features are not yet deprecated. * Importing the deprecated stdlib module ``distutils`` now emits ``deprecated_module`` on Python 3.10+. * ``missing-raises-doc`` will now check the class hierarchy of the raised exceptions .. code-block:: python def my_function() """My function. Raises: Exception: if something fails """ raise ValueError Closes 4955 * Allow disabling ``duplicate-code`` with a disable comment when running through pylint. Closes 214 * Improve ``invalid-name`` check for ``TypeVar`` names. The accepted pattern can be customized with ``--typevar-rgx``. Closes 3401 * Added new checker ``typevar-name-missing-variance``. Emitted when a covariant or contravariant ``TypeVar`` does not end with ``_co`` or ``_contra`` respectively or when a ``TypeVar`` is not either but has a suffix. * Allow usage of mccabe 0.7.x release Closes 5878 * Fix ``unused-private-member`` false positive when accessing private methods through ``property``.
