Pylint's ChangeLog
------------------
What's New in Pylint 2.14.0?
============================
Release date: TBA
..
Put new features here and also in 'doc/whatsnew/2.14.rst'
* We have improved our recognition of inline disable and enable comments. It is
now possible to disable ``bad-option-value`` inline (as long as you disable it before
the bad option value is raised, i.e. ``disable=bad-option-value,bad-message`` not ``disable=bad-message,bad-option-value`` ) as well as certain other previously unsupported messages.
Closes #3312
* Added new checker ``comparison-of-constants``.
Closes #6076
* Started ignoring underscore as a local variable for ``too-many-locals``.
Closes #6488
* Improved wording of the message of ``deprecated-module``
Closes #6169
* ``Pylint`` now requires Python 3.7.2 or newer to run.
Closes #4301
* ``BaseChecker`` classes now require the ``linter`` argument to be passed.
* Fix a failure to respect inline disables for ``fixme`` occurring on the last line
of a module when pylint is launched with ``--enable=fixme``.
* Update ``invalid-slots-object`` message to show bad object rather than its inferred value.
Closes #6101
* The main checker name is now ``main`` instead of ``master``. The configuration does not need to be updated as sections' name are optional.
Closes #5467
* Added new checker ``typevar-name-mismatch``: TypeVar must be assigned to a variable with the same name as its name argument.
Closes #5224
* Pylint can now be installed with an extra-require called ``spelling`` (``pip install pylint[spelling]``).
This will add ``pyenchant`` to pylint's dependencies. You will still need to install the
requirements for ``pyenchant`` (the ``enchant`` library and any dictionaries) yourself. You will also
need to set the ``spelling-dict`` option.
Refs #6462
* Removed the ``assign-to-new-keyword`` message as there are no new keywords in the supported Python
versions any longer.
Closes #4683
* Fixed a crash in the ``not-an-iterable`` checker involving multiple starred expressions
inside a call.
Closes #6372
* Fixed failure to enable ``deprecated-module`` after a ``disable=all``
by making ``ImportsChecker`` solely responsible for emitting ``deprecated-module`` instead
of sharing responsibility with ``StdlibChecker``. (This could have led to double messages.)
* The ``no-init`` (W0232) warning has been removed. It's ok to not have an ``__init__`` in a class.
Closes #2409
* The ``config`` attribute of ``BaseChecker`` has been deprecated. You can use ``checker.linter.config``
to access the global configuration object instead of a checker-specific object.
Ref #5392
* The ``level`` attribute of ``BaseChecker`` has been deprecated: everything is now
displayed in ``--help``, all the time.
Ref #5392
* The ``options_providers`` attribute of ``ArgumentsManager`` has been deprecated.
Ref #5392
* The ``option_groups`` attribute of ``PyLinter`` has been deprecated.
Ref #5392
* All ``Interface`` classes in ``pylint.interfaces`` have been deprecated. You can subclass
the respective normal classes to get the same behaviour. The ``__implements__`` functionality
was based on a rejected PEP from 2001:
https://peps.python.org/pep-0245/
Closes #2287
* The ``set_option`` method of ``BaseChecker`` has been deprecated. You can use ``checker.linter.set_option``
to set an option on the global configuration object instead of a checker-specific object.
Ref #5392
* ``implicit-str-concat`` will now be raised on calls like ``open("myfile.txt" "a+b")`` too.
Closes #6441
* The ``config`` attribute of ``PyLinter`` is now of the ``argparse.Namespace`` type instead of
``optparse.Values``.
Ref #5392
* ``MapReduceMixin`` has been deprecated. ``BaseChecker`` now implements ``get_map_data`` and
``reduce_map_data``. If a checker actually needs to reduce data it should define ``get_map_data``
as returning something different than ``None`` and let its ``reduce_map_data`` handle a list
of the types returned by ``get_map_data``.
An example can be seen by looking at ``pylint/checkers/similar.py``.
* ``UnsupportedAction`` has been deprecated.
Ref #5392
* ``OptionsManagerMixIn`` has been deprecated.
Ref #5392
* ``OptionParser`` has been deprecated.
Ref #5392
* ``Option`` has been deprecated.
Ref #5392
* ``OptionsProviderMixIn`` has been deprecated.
Ref #5392
* ``ConfigurationMixIn`` has been deprecated.
Ref #5392
* ``get_global_config`` has been deprecated. You can now access all global options from
``checker.linter.config``.
Ref #5392
* ``OptionsManagerMixIn`` has been replaced with ``ArgumentsManager``. ``ArgumentsManager`` is considered
private API and most methods that were public on ``OptionsManagerMixIn`` have now been deprecated and will
be removed in a future release.
Ref #5392
* ``OptionsProviderMixIn`` has been replaced with ``ArgumentsProvider``. ``ArgumentsProvider`` is considered
private API and most methods that were public on ``OptionsProviderMixIn`` have now been deprecated and will
be removed in a future release.
Ref #5392
* ``interfaces.implements`` has been deprecated and will be removed in 3.0. Please use standard inheritance
patterns instead of ``__implements__``.
Ref #2287
* ``invalid-enum-extension``: Used when a class tries to extend an inherited Enum class.
Closes #5501
* Added the ``unrecognized-option`` message. Raised if we encounter any unrecognized options.
Closes #5259
* Added new checker ``typevar-double-variance``: The "covariant" and "contravariant" keyword arguments
cannot both be set to "True" in a TypeVar.
Closes #5895
* Re-enable checker ``bad-docstring-quotes`` for Python <= 3.7.
Closes #6087
* Removed the broken ``generate-man`` option.
Closes #5283
Closes #1887
* Fix false negative for ``bad-string-format-type`` if the value to be formatted is passed in
as a variable holding a constant.
* Add new check ``unnecessary-dunder-call`` for unnecessary dunder method calls.
Closes #5936
Closes #6074
* The ``cache-max-size-none`` checker has been renamed to ``method-cache-max-size-none``.
Closes #5670
* The ``method-cache-max-size-none`` checker will now also check ``functools.cache``.
Closes #5670
* ``unnecessary-lambda-assignment``: Lambda expression assigned to a variable.
Define a function using the "def" keyword instead.
``unnecessary-direct-lambda-call``: Lambda expression called directly.
Execute the expression inline instead.
Closes #5976
* ``potential-index-error``: Emitted when the index of a list or tuple exceeds its length.
This checker is currently quite conservative to avoid false positives. We welcome
suggestions for improvements.
Closes #578
* Added optional extension ``redefined-loop-name`` to emit messages when a loop variable
is redefined in the loop body.
Closes #5072
* Changed message type from ``redefined-outer-name`` to ``redefined-loop-name``
(optional extension) for redefinitions of outer loop variables by inner loops.
Closes #5608
* The ``ignore-mixin-members`` option has been deprecated. You should now use the new
``ignored-checks-for-mixins`` option.
Closes #5205
* ``bad-option-value`` will be emitted whenever a configuration value or command line invocation
includes an unknown message.
Closes #4324
* Avoid reporting ``superfluous-parens`` on expressions using the ``is not`` operator.
Closes #5930
* Added the ``super-without-brackets`` checker, raised when a super call is missing its brackets.
Closes #4008
* Added the ``generate-toml-config`` option.
Ref #5462
* Added new checker ``unnecessary-list-index-lookup`` for indexing into a list while
iterating over ``enumerate()``.
Closes #4525

irrelevant messages when running the functional tests.
* ``duplicate-argument-name`` now only raises once for each set of duplicated arguments.
* Fix bug where specifically enabling just ``await-outside-async`` was not possible.
* The ``set_config_directly`` decorator has been removed.
* Added new message called ``duplicate-value`` which identifies duplicate values inside sets.
Closes #5880
* Pylint now expands the user path (i.e. ``~`` to ``home/yusef/``) and expands environment variables (i.e. ``home/$USER/$project``
to ``home/yusef/pylint`` for ``USER=yusef`` and ``project=pylint``) for pyreverse's ``output-directory``,
``import-graph``, ``ext-import-graph``, ``int-import-graph`` options, and the spell checker's ``spelling-private-dict-file``
option.
Relates to #6493
* Created ``NoSelfUseChecker`` extension and moved the ``no-self-use`` check.
You now need to explicitly enable this check using
``load-plugins=pylint.extensions.no_self_use``.
Closes #5502
* Fix saving of persistent data files in environments where the user's cache
directory and the linted file are on a different drive.
Closes #6394
* Don't emit ``unsubscriptable-object`` for string annotations.
Pylint doesn't check if class is only generic in type stubs only.
Closes #4369 and #6523
* ``is_class_subscriptable_pep585_with_postponed_evaluation_enabled`` has been deprecated.
Use ``subscriptable_with_postponed_evaluation_enabled`` instead.

* 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/astroid#1360
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

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://peps.python.org/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://peps.python.org/pep-0008/#source-file-encoding>`_.
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/astroid#1400
* 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/astroid#1392
* 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/astroid#1382
* 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://peps.python.org/pep-0672/#confusing-features>`_
* 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.

was fixed
Closes #1470
Closes #3499

attributes are used as return annotations.
Closes #5568

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.

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

if an except handler did not define the assignment that might have failed
in the try block.

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 #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

``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

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

* 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
