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'
* The refactoring checker now also raises 'consider-using-a-generator' messages for
``max()``, ``min()`` and ``sum()``.
Refs #6595
* 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

* 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
* Fix bug where it writes a plain text error message to stdout, invalidating output formats.
Closes #6597
* ``is_class_subscriptable_pep585_with_postponed_evaluation_enabled`` has been deprecated.
Use ``subscriptable_with_postponed_evaluation_enabled`` instead.

Ref PyCQA/astroid#1360
Closes #4826

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

* 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.

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 #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

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
* ``fatal`` was added to the variables permitted in score evaluation expressions.
* The default score evaluation now uses a floor of 0.
