This PR pins pylint to the latest release 2.12.2.

Changelog ### 2.12.2 ``` ============================ Release date: 2021-11-25 * Fixed a false positive for ``unused-import`` where everything was not analyzed properly inside typing guards. * Fixed a false-positive regression for ``used-before-assignment`` for typed variables in the body of class methods that reference the same class Closes 5342 * Specified that the ``ignore-paths`` option considers "\" to represent a windows directory delimiter instead of a regular expression escape character. * Fixed a crash with the ``ignore-paths`` option when invoking the option via the command line. Closes 5437 * Fixed handling of Sphinx-style parameter docstrings with asterisks. These should be escaped with by prepending a "\". Closes 5406 * Add ``endLine`` and ``endColumn`` keys to output of ``JSONReporter``. Closes 5380 * Fixed handling of Google-style parameter specifications where descriptions are on the line following the parameter name. These were generating false positives for ``missing-param-doc``. Closes 5452 * Fix false negative for ``consider-iterating-dictionary`` during membership checks encapsulated in iterables or ``not in`` checks Closes 5323 * ``unused-import`` now check all ancestors for typing guards Closes 5316 ``` ### 2.12.1 ``` ============================ Release date: 2021-11-25 * Require Python ``3.6.2`` to run pylint. Closes 5065 ``` ### 2.12.0 ``` ============================ Release date: 2021-11-24 * Upgrade astroid to 2.9.0 Closes 4982 * Add ability to add ``end_line`` and ``end_column`` to the ``--msg-template`` option. With the standard ``TextReporter`` this will add the line and column number of the end of a node to the output of Pylint. If these numbers are unknown, they are represented by an empty string. * Introduced primer tests and a configuration tests framework. The helper classes available in ``pylint/testutil/`` are still unstable and might be modified in the near future. Closes 4412 5287 * Fix ``install graphiz`` message which isn't needed for puml output format. * ``MessageTest`` of the unittest ``testutil`` now requires the ``confidence`` attribute to match the expected value. If none is provided it is set to ``UNDEFINED``. * ``add_message`` of the unittest ``testutil`` now actually handles the ``col_offset`` parameter and allows it to be checked against actual output in a test. * Fix a crash in the ``check_elif`` extensions where an undetected if in a comprehension with an if statement within a f-string resulted in an out of range error. The checker no longer relies on counting if statements anymore and uses known if statements locations instead. It should not crash on badly parsed if statements anymore. * Fix ``simplify-boolean-expression`` when condition can be inferred as False. Closes 5200 * Fix exception when pyreverse parses ``property function`` of a class. * The functional ``testutils`` now accept ``end_lineno`` and ``end_column``. Expected output files without these will trigger a ``DeprecationWarning``. Expected output files can be easily updated with the ``python tests/test_functional.py --update-functional-output`` command. * The functional ``testutils`` now correctly check the distinction betweeen ``HIGH`` and ``UNDEFINED`` confidence. Expected output files without defiend ``confidence`` levels will now trigger a ``DeprecationWarning``. Expected output files can be easily updated with the ``python tests/test_functional.py --update-functional-output`` command. * The functional test runner now supports the option ``min_pyver_end_position`` to control on which python versions the ``end_lineno`` and ``end_column`` attributes should be checked. The default value is 3.8. * Fix ``accept-no-yields-doc`` and ``accept-no-return-doc`` not allowing missing ``yield`` or ``return`` documentation when a docstring is partially correct Closes 5223 * Add an optional extension ``consider-using-any-or-all`` : Emitted when a ``for`` loop only produces a boolean and could be replaced by ``any`` or ``all`` using a generator. Also suggests a suitable any or all statement. Closes 5008 * Properly identify parameters with no documentation and add new message called ``missing-any-param-doc`` Closes 3799 * Add checkers ``overridden-final-method`` & ``subclassed-final-class`` Closes 3197 * Fixed ``protected-access`` for accessing of attributes and methods of inner classes Closes 3066 * Added support for ``ModuleNotFoundError`` (``import-error`` and ``no-name-in-module``). ``ModuleNotFoundError`` inherits from ``ImportError`` and was added in Python ``3.6`` * ``undefined-variable`` now correctly flags variables which only receive a type annotations and never get assigned a value Closes 5140 * ``undefined-variable`` now correctly considers the line numbering and order of classes used in metaclass declarations Closes 4031 * ``used-before-assignment`` now correctly considers references to classes as type annotation or default values in first-level methods Closes 3771 * ``undefined-variable`` and ``unused-variable`` now correctly trigger for assignment expressions in functions defaults Fixes part of 3688 * ``undefined-variable`` now correctly triggers for assignment expressions in if ... else statements This includes a basic form of control flow inference for if ... else statements using constant boolean values Closes 3688 * Added the ``--enable-all-extensions`` command line option. It will load all available extensions which can be listed by running ``--list-extensions`` * Fix bug with importing namespace packages with relative imports Closes 2967 and 5131 * Improve and flatten ``unused-wildcard-import`` message Closes 3859 * In length checker, ``len-as-condition`` has been renamed as ``use-implicit-booleaness-not-len`` in order to be consistent with ``use-implicit-booleaness-not-comparison``. * Created new ``UnsupportedVersionChecker`` checker class that includes checks for features not supported by all versions indicated by a ``py-version``. * Added ``using-f-string-in-unsupported-version`` checker. Issued when ``py-version`` is set to a version that does not support f-strings (< 3.6) * Fix ``useless-super-delegation`` false positive when default keyword argument is a variable. * Properly emit ``duplicate-key`` when Enum members are duplicate dictionary keys Closes 5150 * Use ``py-version`` setting for alternative union syntax check (PEP 604), instead of the Python interpreter version. * Subclasses of ``dict`` are regarded as reversible by the ``bad-reversed-sequence`` checker (Python 3.8 onwards). Closes 4981 * Support configuring mixin class pattern via ``mixin-class-rgx`` * Added new checker ``use-implicit-booleaness-not-comparison``: Emitted when collection literal comparison is being used to check for emptiness. Closes 4774 * ``mising-param-doc`` now correctly parses asterisks for variable length and keyword parameters Closes 3733 * ``mising-param-doc`` now correctly handles Numpy parameter documentation without explicit typing Closes 5222 * ``pylint`` no longer crashes when checking assignment expressions within if-statements Closes 5178 * Update ``literal-comparison checker to ignore tuple literals Closes 3031 * Normalize the input to the ``ignore-paths`` option to allow both Posix and Windows paths Closes 5194 * Fix double emitting of ``not-callable`` on inferrable ``properties`` Closes 4426 * ``self-cls-assignment`` now also considers tuple assignment * Fix ``missing-function-docstring`` not being able to check ``__init__`` and other magic methods even if the ``no-docstring-rgx`` setting was set to do so * Added ``using-final-decorator-in-unsupported-version`` checker. Issued when ``py-version`` is set to a version that does not support ``typing.final`` (< 3.8) * Added configuration option ``exclude-too-few-public-methods`` to allow excluding classes from the ``min-public-methods`` checker. Closes 3370 * The ``--jobs`` parameter now fallbacks to 1 if the host operating system does not have functioning shared semaphore implementation. Closes 5216 * Fix crash for ``unused-private-member`` when checking private members on ``__class__`` Closes 5261 * Crashes when a list is encountered in a toml configuration do not happen anymore. Closes 4580 * Moved ``misplaced-comparison-constant`` to its own extension ``comparison_placement``. This checker was opinionated and now no longer a default. It can be reactived by adding ``pylint.extensions.comparison_placement`` to ``load-plugins`` in your config. Closes 1064 * A new ``bad-configuration-section`` checker was added that will emit for misplaced option in pylint's top level namespace for toml configuration. Top-level dictionaries or option defined in the wrong section will still silently not be taken into account, which is tracked in a follow-up issue. Follow-up in 5259 * Fix crash for ``protected-access`` on (outer) class traversal * Added new checker ``useless-with-lock`` to find incorrect usage of with statement and threading module locks. Emitted when ``with threading.Lock():`` is used instead of ``with lock_instance:``. Closes 5208 * Make yn validator case insensitive, to allow for ``True`` and ``False`` in config files. * Fix crash on ``open()`` calls when the ``mode`` argument is not a simple string. Partially closes 5321 * Inheriting from a class that implements ``__class_getitem__`` no longer raises ``inherit-non-class``. * Pyreverse - Add the project root directory to sys.path Closes 2479 * Don't emit ``consider-using-f-string`` if ``py-version`` is set to Python < ``3.6``. ``f-strings`` were added in Python ``3.6`` Closes 5019 * Fix regression for ``unspecified-encoding`` with ``pathlib.Path.read_text()`` Closes 5029 * Don't emit ``consider-using-f-string`` if the variables to be interpolated include a backslash * Fixed false positive for ``cell-var-from-loop`` when variable is used as the default value for a keyword-only parameter. Closes 5012 * Fix false-positive ``undefined-variable`` with ``Lambda``, ``IfExp``, and assignment expression. * Fix false-positive ``useless-suppression`` for ``wrong-import-order`` Closes 2366 * Fixed ``toml`` dependency issue Closes 5066 * Fix false-positive ``useless-suppression`` for ``line-too-long`` Closes 4212 * Fixed ``invalid-name`` not checking parameters of overwritten base ``object`` methods Closes 3614 * Fixed crash in ``consider-using-f-string`` if ``format`` is not called Closes 5058 * Fix crash with ``AssignAttr`` in ``if TYPE_CHECKING`` blocks. Closes 5111 * Improve node information for ``invalid-name`` on function argument. * Prevent return type checkers being called on functions with ellipses as body Closes 4736 * Add ``is_sys_guard`` and ``is_typing_guard`` helper functions from astroid to ``pylint.checkers.utils``. * Fix regression on ClassDef inference Closes 5030 Closes 5036 * Fix regression on Compare node inference Closes 5048 * Fix false-positive ``isinstance-second-argument-not-valid-type`` with ``typing.Callable``. Closes 3507 Closes 5087 * It is now recommended to do ``pylint`` development on ``Python`` 3.8 or higher. This allows using the latest ``ast`` parser. * All standard jobs in the ``pylint`` CI now run on ``Python`` 3.8 by default. We still support python 3.6 and 3.7 and run tests for those interpreters. * ``TypingChecker`` * Fix false-negative for ``deprecated-typing-alias`` and ``consider-using-alias`` with ``typing.Type`` + ``typing.Callable``. ``` ### 2.11.1 ``` ============================ Release date: 2021-09-16 * ``unspecified-encoding`` now checks the encoding of ``pathlib.Path()`` correctly Closes 5017 ``` ### 2.11.0 ``` ============================ Release date: 2021-09-16 * The python3 porting mode checker and it's ``py3k`` option were removed. You can still find it in older pylint versions. * ``raising-bad-type`` is now properly emitted when raising a string * Added new extension ``SetMembershipChecker`` with ``use-set-for-membership`` check: Emitted when using an in-place defined ``list`` or ``tuple`` to do a membership test. ``sets`` are better optimized for that. Closes 4776 * Added ``py-version`` config key (if ``[MASTER]`` section). Used for version dependant checks. Will default to whatever Python version pylint is executed with. * ``CodeStyleChecker`` * Added ``consider-using-assignment-expr``: Emitted when an assignment is directly followed by an if statement and both can be combined by using an assignment expression ``:=``. Requires Python 3.8 Closes 4862 * Added ``consider-using-f-string``: Emitted when .format() or '%' is being used to format a string. Closes 3592 * Fix false positive for ``consider-using-with`` if a context manager is assigned to a variable in different paths of control flow (e. g. if-else clause).

Closes 4405 * scm_setuptools has been added to the packaging. * Pylint's tags are now the standard form ``vX.Y.Z`` and not ``pylint-X.Y.Z`` anymore. * New warning message ``deprecated-class``. This message is emitted if import or call deprecated class of the standard library (like ``collections.Iterable`` that will be removed in Python 3.10). Closes 4388 ``` ### 2.8.1 ``` =========================== Release date: 2021-04-25 * Add numversion back (temporarily) in ``__pkginfo__`` because it broke Pylama and revert the unnecessary ``pylint.version`` breaking change.

Closes 3413 * Resolve false positives on unused variables in decorator functions Closes 4252 * Add new extension ``ConfusingConsecutiveElifChecker``. This optional checker emits a refactoring message (R5601 ``confusing-consecutive-elif``) if if/elif statements with different indentation levels follow directly one after the other. * New option ``--output=<file>`` to output result to a file rather than printing to stdout. Closes 1070 * Use a prescriptive message for ``unidiomatic-typecheck`` Closes 3891 * Apply ``const-naming-style`` to module constants annotated with ``typing.Final`` * The packaging is now done via setuptools exclusively. ``doc``, ``tests``, ``man``, ``elisp`` and ``Changelog`` are not packaged anymore - reducing the size of the package by 75%. * Debian packaging is now (officially) done in https://salsa.debian.org/python-team/packages/pylint. * The 'doc' extra-require has been removed. * ``__pkginfo__`` now only contain ``__version__`` (also accessible with ``pylint.__version__``), other meta-information are still accessible with ``from importlib import metadata;metadata.metadata('pylint')``. * COPYING has been renamed to LICENSE for standardization. * Fix false-positive ``used-before-assignment`` in function returns. Closes 4301 * Updated ``astroid`` to 2.5.3 Closes 2822, 4206, 4284 * Add ``consider-using-min-max-builtin`` check for if statement which could be replaced by Python builtin min or max Closes 3406 * Don't auto-enable postponed evaluation of type annotations with Python 3.10 * Update ``astroid`` to 2.5.4 * Add new extension ``TypingChecker``. This optional checker can detect the use of deprecated typing aliases and can suggest the use of the alternative union syntax where possible. (For example, 'typing.Dict' can be replaced by 'dict', and 'typing.Unions' by '|', etc.) Make sure to check the config options if you plan on using it! * Reactivates old counts in report mode. Closes 3819 * During detection of ``inconsistent-return-statements`` consider that ``assert False`` is a return node. Closes 4019 * Run will not fail if score exactly equals ``config.fail_under``. * Functions that never returns may declare ``NoReturn`` as type hints, so that ``inconsistent-return-statements`` is not emitted. Closes 4122, 4188 * Improved protected access checks to allow access inside class methods Closes 1159 * Fix issue with PEP 585 syntax and the use of ``collections.abc.Set`` * Fix issue that caused class variables annotated with ``typing.ClassVar`` to be identified as class constants. Now, class variables annotated with ``typing.Final`` are identified as such. Closes 4277 * Continuous integration with read the doc has been added. Closes 3850 * Don't show ``DuplicateBasesError`` for attribute access * Fix crash when checking ``setup.cfg`` for pylint config when there are non-ascii characters in there Closes 4328 * Allow code flanked in backticks to be skipped by spellchecker Closes 4319 * Allow Python tool directives (for black, flake8, zimports, isort, mypy, bandit, pycharm) at beginning of comments to be skipped by spellchecker Closes 4320 * Fix issue that caused emacs pylint to fail when used with tramp * Improve check for invalid PEP 585 syntax inside functions if postponed evaluation of type annotations is enabled * Improve check for invalid PEP 585 syntax as default function arguments ``` ### 2.7.4 ``` =========================== Release date: 2021-03-30 * Fix a problem with disabled msgid not being ignored Closes 4265 * Fix issue with annotated class constants Closes 4264 ``` ### 2.7.3 ``` =========================== Release date: 2021-03-29 * Introduce logic for checking deprecated attributes in DeprecationMixin. * Reduce usage of blacklist/whitelist terminology. Notably, ``extension-pkg-allow-list`` is an alternative to ``extension-pkg-whitelist`` and the message ``blacklisted-name`` is now emitted as ``disallowed-name``. The previous names are accepted to maintain backward compatibility. * Move deprecated checker to ``DeprecatedMixin`` Closes 4086 * Bump ``astroid`` version to ``2.5.2`` * Fix false positive for ``method-hidden`` when using private attribute and method Closes 3936 * ``use-symbolic-message-instead`` now also works on legacy messages like ``C0111`` (``missing-docstring``). * Remove unwanted print to stdout from ``_emit_no_member`` * Introduce a command-line option to specify pyreverse output directory Closes 4159 * Fix issue with Enums and ``class-attribute-naming-style=snake_case`` Closes 4149 * Add ``allowed-redefined-builtins`` option for fine tuning ``redefined-builtin`` check. Close 3263 * Fix issue when executing with ``python -m pylint`` Closes 4161 * Exempt ``typing.TypedDict`` from ``too-few-public-methods`` check. Closes 4180 * Fix false-positive ``no-member`` for typed annotations without default value. Closes 3167 * Add ``--class-const-naming-style`` for Enum constants and class variables annotated with ``typing.ClassVar`` Closes 4181 * Fix astroid.Inference error for undefined-variables with ``len() Closes 4215 * Fix column index on FIXME warning messages Closes 4218 * Improve handling of assignment expressions, better edge case handling Closes 3763, 4238 * Improve check if class is subscriptable PEP585 * Fix documentation and filename handling of --import-graph * Fix false-positive for ``unused-import`` on class keyword arguments Closes 3202 * Fix regression with plugins on PYTHONPATH if latter is cwd Closes 4252 ``` ### 2.7.2 ``` =========================== Release date: 2021-02-28 * Fix False Positive on ``Enum.__members__.items()``, ``Enum.__members__.values``, and ``Enum.__members__.keys`` Closes 4123 * Properly strip dangerous sys.path entries (not just the first one) Closes 3636 * Workflow and packaging improvements ``` ### 2.7.1 ``` =========================== Release date: 2021-02-23 * Expose ``UnittestLinter`` in pylint.testutils * Don't check directories starting with '.' when using register_plugins Closes 4119 ``` ### 2.7.0 ``` =========================== Release date: 2021-02-21 * Introduce DeprecationMixin for reusable deprecation checks. Closes 4049 * Fix false positive for ``builtin-not-iterating`` when ``map`` receives iterable Closes 4078 * Python 3.6+ is now required. * Fix false positive for ``builtin-not-iterating`` when ``zip`` receives iterable * Add ``nan-comparison`` check for NaN comparisons * Bug fix for empty-comment message line number. Closes 4009 * Only emit ``bad-reversed-sequence`` on dictionaries if below py3.8 Closes 3940 * Handle class decorators applied to function. Closes 3882 * Add check for empty comments * Fix minor documentation issue in contribute.rst * Enums are now required to be named in UPPER_CASE by ``invalid-name``. Close 3834 * Add missing checks for deprecated functions. * Postponed evaluation of annotations are now recognized by default if python version is above 3.10 Closes 3992 * Fix column metadata for anomalous backslash lints * Drop support for Python 3.5 * Add support for pep585 with postponed evaluation Closes 3320 * Check alternative union syntax - PEP 604 Closes 4065 * Fix multiple false positives with assignment expressions Closes 3347, 3953, 3865, 3275 * Fix TypedDict inherit-non-class false-positive Python 3.9+ Closes 1927 * Fix issue with nested PEP 585 syntax * Fix issue with nested PEP 604 syntax * Fix a crash in ``undefined-variable`` caused by chained attributes in metaclass Close 3742 * Fix false positive for ``not-async-context-manager`` when ``contextlib.asynccontextmanager`` is used Close 3862 * Fix linter multiprocessing pool shutdown (triggered warnings when runned in parallels with other pytest plugins) Closes 3779 * Fix a false-positive emission of ``no-self-use`` and ``unused-argument`` for methods of generic structural types (`Protocol[T]`) Closes 3885 * Fix bug that lead to duplicate messages when using ``--jobs 2`` or more. Close 3584 * Adds option ``check-protected-access-in-special-methods`` in the ClassChecker to activate/deactivate ``protected-access`` message emission for single underscore prefixed attribute in special methods. Close 3120 * Fix vulnerable regular expressions in ``pyreverse`` Close 3811 * ``inconsistent-return-statements`` message is now emitted if one of ``try/except`` statement is not returning explicitly while the other do. Closes 3468 * Fix ``useless-super-delegation`` false positive when default keyword argument is a dictionnary. Close 3773 * Fix a crash when a specified config file does not exist * Add support to ``ignored-argument-names`` in DocstringParameterChecker and adds ``useless-param-doc`` and ``useless-type-doc`` messages. Close 3800 * Enforce docparams consistently when docstring is not present Close 2738 * Fix ``duplicate-code`` false positive when lines only contain whitespace and non-alphanumeric characters (e.g. parentheses, bracket, comma, etc.) * Improve lint message for ``singleton-comparison`` with bools * Fix spell-checker crash on indented docstring lines that look like comments Close 3786 * Fix AttributeError in checkers/refactoring.py * Improve sphinx directives spelling filter * Fix a bug with postponed evaluation when using aliases for annotations. Close 3798 * Fix minor documentation issues * Improve the performance of the line length check. * Removed incorrect deprecation of ``inspect.getfullargspec`` * Fix ``signature-differs`` false positive for functions with variadics Close 3737 * Fix a crash in ``consider-using-enumerate`` when encountering ``range()`` without arguments Close 3735 * ``len-as-conditions`` is now triggered only for classes that are inheriting directly from list, dict, or set and not implementing the ``__bool__`` function, or from generators like range or list/dict/set comprehension. This should reduce the false positives for other classes, like pandas's DataFrame or numpy's Array. Close 1879 * Fixes duplicate-errors not working with -j2+ Close 3314 * ``generated-members`` now matches the qualified name of members Close 2498 * Add check for bool function to ``len-as-condition`` * Add ``simplifiable-condition`` check for extraneous constants in conditionals using and/or. * Add ``condition-evals-to-constant`` check for conditionals using and/or that evaluate to a constant. Close 3407 * Changed setup.py to work with `distlib <https://pypi.org/project/distlib>`_ Close 3555 * New check: ``consider-using-generator`` This check warns when a comprehension is used inside an ``any`` or ``all`` function, since it is unnecessary and should be replaced by a generator instead. Using a generator would be less code and way faster. Close 3165 * Add Github Actions to replace Travis and AppVeyor in the future ``` ### 2.6.1 ``` =========================== Release date: 2021-02-16 * Astroid version has been set as < 2.5 Close 4093 ``` ### 2.6.0 ``` =========================== Release date: 2020-08-20 * Fix various scope-related bugs in ``undefined-variable`` checker Close 1082, 3434, 3461 * bad-continuation and bad-whitespace have been removed, black or another formatter can help you with this better than Pylint Close 246, 289, 638, 747, 1148, 1179, 1943, 2041, 2301, 2304, 2944, 3565 * The no-space-check option has been removed. It's no longer possible to consider empty line like a ``trailing-whitespace`` by using clever options Close 1368 * ``missing-kwoa`` is no longer emitted when dealing with overload functions Close 3655 * mixed-indentation has been removed, it is no longer useful since TabError is included directly in python3 Close 2984 3573 * Add ``super-with-arguments`` check for flagging instances of Python 2 style super calls. * Add an faq detailing which messages to disable to avoid duplicates w/ other popular linters * Fix superfluous-parens false-positive for the walrus operator Close 3383 * Fix ``fail-under`` not accepting floats * Fix a bug with ``ignore-docstrings`` ignoring all lines in a module * Fix ``pre-commit`` config that could lead to undetected duplicate lines of code * Fix a crash in parallel mode when the module's filepath is not set Close 3564 * Add ``raise-missing-from`` check for exceptions that should have a cause. * Support both isort 4 and isort 5. If you have pinned isort 4 in your projet requirements, nothing changes. If you use isort 5, though, note that the ``known-standard-library`` option is not interpreted the same in isort 4 and isort 5 (see the migration guide in isort documentation for further details). For compatibility's sake for most pylint users, the ``known-standard-library`` option in pylint now maps to ``extra-standard-library`` in isort 5. If you really want what ``known-standard-library`` now means in isort 5, you must disable the ``wrong-import-order`` check in pylint and run isort manually with a proper isort configuration file. Close 3722 * Fix a crash caused by not guarding against ``InferenceError`` when calling ``infer_call_result`` Close 3690 * Fix a crash in parallel mode when the module's filepath is not set Close 3564 ``` ### 2.5.3 ``` =========================== Release date: 2020-06-8 * Fix a regression where disable comments that have checker names with numbers in them are not parsed correctly Close 3666 * ``property-with-parameters`` properly handles abstract properties Close 3600 * ``continue-in-finally`` no longer emitted on Python 3.8 where it's now valid Close 3612 * Fix a regression where messages with dash are not fully parsed Close 3604 * In a TOML configuration file, it's now possible to use rich (non-string) types, such as list, integer or boolean instead of strings. For example, one can now define a *list* of message identifiers to enable like this:: enable = [ "use-symbolic-message-instead", "useless-suppression", ] Close 3538 * Fix a regression where the score was not reported with multiple jobs Close 3547 * Protect against ``AttributeError`` when checking ``cell-var-from-loop`` Close 3646 ``` ### 2.5.2 ``` =========================== Release date: 2020-05-05 * ``pylint.Run`` accepts ``do_exit`` as a deprecated parameter Close 3590 ``` ### 2.5.1 ``` =========================== Release date: 2020-05-05 * Fix a crash in ``method-hidden`` lookup for unknown base classes Close 3527 * Revert pylint.Run's ``exit`` parameter to ``do_exit`` This has been inadvertently changed several releases ago to ``do_exit``. Close 3533 * ``no-value-for-parameter`` variadic detection has improved for assign statements Close 3563 * Allow package files to be properly discovered with multiple jobs Close 3524 * Allow linting directories without ``__init__.py`` which was a regression in 2.5. Close 3528 ``` ### 2.5.0 ``` =========================== Release date: 2020-04-27 * Fix a false negative for ``undefined-variable`` when using class attribute in comprehension. Close 3494 * Fix a false positive for ``undefined-variable`` when using class attribute in decorator or as type hint. Close 511 Close 1976 * Remove HTML quoting of messages in JSON output. Close 2769 * Adjust the ``invalid-name`` rule to work with non-ASCII identifiers and add the ``non-ascii-name`` rule. Close 2725 * Positional-only arguments are taken in account for ``useless-super-delegation`` * ``unidiomatic-typecheck`` is no longer emitted for ``in`` and ``not in`` operators Close 3337 * Positional-only argument annotations are taken in account for ``unused-import`` Close 3462 * Add a command to list available extensions. * Allow used variables to be properly consumed when different checks are enabled / disabled Close 3445 * Fix dangerous-default-value rule to account for keyword argument defaults Close 3373 * Fix a false positive of ``self-assigning-variable`` on tuple unpacking. Close 3433 * ``no-self-use`` is no longer emitted for typing stubs. Close 3439 * Fix a false positive for ``undefined-variable`` when ``__class__`` is used Close 3090 * Emit ``invalid-name`` for variables defined in loops at module level. Close 2695 * Add a check for cases where the second argument to ``isinstance`` is not a type. Close 3308 * Add 'notes-rgx' option, to be used for fixme check. Close 2874 * ``function-redefined`` exempts function redefined on a condition. Close 2410 * ``typing.overload`` functions are exempted from docstring checks Close 3350 * Emit ``invalid-overridden-method`` for improper async def overrides. Close 3355 * Do not allow ``python -m pylint ...`` to import user code ``python -m pylint ...`` adds the current working directory as the first element of ``sys.path``. This opens up a potential security hole where ``pylint`` will import user level code as long as that code resides in modules having the same name as stdlib or pylint's own modules. Close 3386 * Add ``dummy-variables-rgx`` option for ``_redeclared-assigned-name`` check. Close 3341 * Fixed graph creation for relative paths * Add a check for asserts on string literals. Close 3284 * ``not in`` is considered iterating context for some of the Python 3 porting checkers. * A new check ``inconsistent-quotes`` was added. * Add a check for non string assignment to __name__ attribute. Close 583 * ``__pow__``, ``__imatmul__``, ``__trunc__``, ``__floor__``, and ``__ceil__`` are recognized as special method names. Close 3281 * Added errors for protocol functions when invalid return types are detected. E0304 (invalid-bool-returned): __bool__ did not return a bool E0305 (invalid-index-returned): __index__ did not return an integer E0306 (invalid-repr-returned): __repr__ did not return a string E0307 (invalid-str-returned): __str__ did not return a string E0308 (invalid-bytes-returned): __bytes__ did not return a string E0309 (invalid-hash-returned): __hash__ did not return an integer E0310 (invalid-length-hint-returned): __length_hint__ did not return a non-negative integer E0311 (invalid-format-returned): __format__ did not return a string E0312 (invalid-getnewargs-returned): __getnewargs__ did not return a tuple E0313 (invalid-getnewargs-ex-returned): __getnewargs_ex__ did not return a tuple of the form (tuple, dict) Close 560 * ``missing-*-docstring`` can look for ``__doc__`` assignments. Close 3301 * ``undefined-variable`` can now find undefined loop iterables Close 498 * ``safe_infer`` can infer a value as long as all the paths share the same type. Close 2503 * Add a --fail-under <score> flag, also configurable in a .pylintrc file. If the final score is more than the specified score, it's considered a success and pylint exits with exitcode 0. Otherwise, it's considered a failure and pylint exits with its current exitcode based on the messages issued. Close 2242 * Don't emit ``line-too-long`` for multilines when ``disable=line-too-long`` comment stands at their end Close 2957 * Fixed an ``AttributeError`` caused by improper handling of ``dataclasses`` inference in ``pyreverse`` Close 3256 * Do not exempt bare except from ``undefined-variable`` and similar checks If a node was wrapped in a ``TryExcept``, ``pylint`` was taking a hint from the except handler when deciding to emit or not a message. We were treating bare except as a fully fledged ignore but only the corresponding exceptions should be handled that way (e.g. ``NameError`` or ``ImportError``) Close 3235 * No longer emit ``assignment-from-no-return`` when a function only raises an exception Close 3218 * Allow import aliases to exempt ``import-error`` when used in type annotations. Close 3178 * ``Ellipsis` is exempted from ``multiple-statements`` for function overloads. Close 3224 * No longer emit ``invalid-name`` for non-constants found at module level. Pylint was taking the following statement from PEP-8 too far, considering all module level variables as constants, which is not what the statement is saying: `Constants are usually defined on a module level and written in all capital letters with underscores separating words.` Close 3111 Close 3132 * Allow ``implicit-str-concat-in-sequence`` to be emitted for string juxtaposition Close 3030 * ``implicit-str-concat-in-sequence`` was renamed ``implicit-str-concat`` * The ``json`` reporter no longer bypasses ``redirect_stdout``. Close 3227 * Move ``NoFileError``, ``OutputLine``, ``FunctionalTestReporter``, ``FunctionalTestFile``, ``LintModuleTest`` and related methods from ``test_functional.py`` to ``pylint.testutils`` to help testing for 3rd party pylint plugins. * Can read config from a setup.cfg or pyproject.toml file. Close 617 * Fix exception-escape false positive with generators Close 3128 * ``inspect.getargvalues`` is no longer marked as deprecated. * A new check ``f-string-without-interpolation`` was added Close 3190 * Flag mutable ``collections.*`` utilities as dangerous defaults Close 3183 * ``docparams`` extension supports multiple types in raises sections. Multiple types can also be separated by commas in all valid sections. Closes 2729 * Allow parallel linting when run under Prospector * Fixed false positives of ``method-hidden`` when a subclass defines the method that is being hidden. Closes 414 * Python 3 porting mode is 30-50% faster on most codebases * Python 3 porting mode no longer swallows syntax errors Closes 2956 * Pass the actual PyLinter object to sub processes to allow using custom PyLinter classes. PyLinter object (and all its members except reporter) needs to support pickling so the PyLinter object can be passed to worker processes. * Clean up setup.py Make pytest-runner a requirement only if running tests, similar to McCabe. Clean up the setup.py file, resolving a number of warnings around it. * Handle SyntaxError in files passed via ``--from-stdin`` option Pylint no longer outputs a traceback, if a file, read from stdin, contains a syntaxerror. * Fix uppercase style to disallow 3+ uppercase followed by lowercase. * Fixed ``undefined-variable`` and ``unused-import`` false positives when using a metaclass via an attribute. Close 1603 * Emit ``unused-argument`` for functions that partially uses their argument list before raising an exception. Close 3246 * Fixed ``broad_try_clause`` extension to check try/finally statements and to check for nested statements (e.g., inside of an ``if`` statement). * Recognize classes explicitly inheriting from ``abc.ABC`` or having an ``abc.ABCMeta`` metaclass as abstract. This makes them not trigger W0223. Closes 3098 * Fix overzealous ``arguments-differ`` when overridden function uses variadics No message is emitted if the overriding function provides positional or keyword variadics in its signature that can feasibly accept and pass on all parameters given by the overridden function. Close 1482 Close 1553 * Multiple types of string formatting are allowed in logging functions. The ``logging-fstring-interpolation`` message has been brought back to allow multiple types of string formatting to be used. Close 3361 ``` ### 2.4.4 ``` =========================== Release date: 2019-11-13 * Exempt all the names found in type annotations from ``unused-import`` The previous code was assuming that only ``typing`` names need to be exempted, but we need to do that for the rest of the type comment names as well. Close 3112 * Relax type import detection for names that do not come from the ``typing`` module Close 3191 ``` ### 2.4.3 ``` =========================== Release date: 2019-10-18 * Fix an issue with ``unnecessary-comprehension`` in comprehensions with additional repacking of elements. Close 3148 * ``import-outside-toplevel`` is emitted for ``ImportFrom`` nodes as well. Close 3175 * Do not emit ``no-method-argument`` for functions using positional only args. Close 3161 * ``consider-using-sys-exit`` is no longer emitted when ``exit`` is imported in the local scope. Close 3147 * ``invalid-overridden-method`` takes ``abc.abstractproperty`` in account Close 3150 * Fixed ``missing-yield-type-doc`` getting incorrectly raised when a generator does not document a yield type but has a type annotation. Closes 3185 * ``typing.overload`` functions are exempted from ``too-many-function-args`` Close 3170 ``` ### 2.4.2 ``` =========================== Release date: 2019-09-30 * ``ignored-modules`` can skip submodules. Close 3135 * ``self-assigning-variable`` skips class level assignments. Close 2930 * ``consider-using-sys-exit`` is exempted when ``exit()`` is imported from ``sys`` Close 3145 * Exempt annotated assignments without variable from ``class-variable-slots-conflict`` Close 3141 * Fix ``utils.is_error`` to account for functions returning early. This fixes a false negative with ``unused-variable`` which was no longer triggered when a function raised an exception as the last instruction, but the body of the function still had unused variables. Close 3028 ``` ### 2.4.1 ``` =========================== Release date: 2019-09-25 * Exempt type checking definitions defined in both clauses of a type checking guard Close 3127 * Exempt type checking definitions inside the type check guard In a7f236528bb3758886b97285a56f3f9ce5b13a99 we added basic support for emitting ``used-before-assignment`` if a variable was only defined inside a type checking guard (using ``TYPE_CHECKING`` variable from `typing`) Unfortunately that missed the case of using those type checking imports inside the guard itself, which triggered spurious used-before-assignment errors. Close 3119 * Require astroid >= 2.3 to avoid any compatibility issues. ``` ### 2.4.0 ``` =========================== Release date: 2019-09-24 * New check: ``import-outside-toplevel`` This check warns when modules are imported from places other than a module toplevel, e.g. inside a function or a class. * Handle inference ambiguity for ``invalid-format-index`` Close 2752 * Removed Python 2 specific checks such as ``relative-import``, ``invalid-encoded-data``, ``missing-super-argument``. * Support forward references for ``function-redefined`` check. Close 2540 * Handle redefinitions in case of type checking imports. Close 2834 * Added a new check, ``consider-using-sys-exit`` This check is emitted when we detect that a quit() or exit() is invoked instead of sys.exit(), which is the preferred way of exiting in program. Close 2925 * ``useless-suppression`` check now ignores ``cyclic-import`` suppressions, which could lead to false postiives due to incomplete context at the time of the check. Close 3064 * Added new checks, ``no-else-break`` and ``no-else-continue`` These checks highlight unnecessary ``else`` and ``elif`` blocks after ``break`` and ``continue`` statements. Close 2327 * Don't emit ``protected-access`` when a single underscore prefixed attribute is used inside a special method Close 1802 * Fix the "statement" values in the PyLinter's stats reports by module. * Added a new check, ``invalid-overridden-method`` This check is emitted when we detect that a method is overridden as a property or a property is overridden as a method. This can indicate a bug in the application code that will trigger a runtime error. Close 2670 * Added a new check, ``arguments-out-of-order`` This check warns if you have arguments with names that match those in a function's signature but you are passing them in to the function in a different order. Close 2975 * Added a new check, ``redeclared-assigned-name`` This check is emitted when ``pylint`` detects that a name was assigned one or multiple times in the same assignment, which indicate a potential bug. Close 2898 * Ignore lambda calls with variadic arguments without a context. Inferring variadic positional arguments and keyword arguments will result into empty Tuples and Dicts, which can lead in some cases to false positives with regard to no-value-for-parameter. In order to avoid this, until we'll have support for call context propagation, we're ignoring such cases if detected. We already did that for function calls, but the previous fix was not taking in consideration ``lambdas`` Close 2918 * Added a new check, ``self-assigning-variable`` This check is emitted when we detect that a variable is assigned to itself, which might indicate a potential bug in the code application. Close 2930 * Added a new check, ``property-with-parameters``. This check is emitted when we detect that a defined property also has parameters, which are useless. Close 3006 * Excluded protocol classes from a couple of checks. Close 3002. * Add a check ``unnecessary-comprehension`` that detects unnecessary comprehensions. This check is emitted when ``pylint`` finds list-, set- or dict-comprehensions, that are unnecessary and can be rewritten with the list-, set- or dict-constructors. Close 2905 * Excluded PEP 526 instance and class variables from ``no-member``. Close 2945 * Excluded ``attrs`` from ``too-few-public-methods`` check. Close 2988. * ``unused-import`` emitted for the right import names in function scopes. Close 2928 * Dropped support for Python 3.4. * ``assignment-from-no-return`` not triggered for async methods. Close 2902 * Don't emit ``attribute-defined-outside-init`` for variables defined in setters. Close 409 * Syntax errors report the column number. Close 2914 * Support fully qualified typing imports for type annotations. Close 2915 * Exclude ``__dict__`` from ``attribute-defined-outside-init`` * Fix pointer on spelling check when the error are more than one time in the same line. Close 2895 * Fix crash happening when parent of called object cannot be determined * Allow of in ``GoogleDocstring.re_multiple_type`` * Added ``subprocess-run-check`` to handle subrocess.run without explicitly set ``check`` keyword. Close 2848 * When we can't infer bare except handlers, skip ``try-except-raise`` Close 2853 * Handle more ``unnecessary-lambda`` cases when dealing with additional kwargs in wrapped calls Close 2845 * Better postponed evaluation of annotations handling Close 2847 * Support postponed evaluation of annotations for variable annotations. Close 2838 * ``epylint.py_run`` defaults to ``python`` in case the current executable is not a Python one. Close 2837 * Ignore raw docstrings when running Similarities checker with ``ignore-docstrings=yes`` option * Fix crash when calling ``inherit_from_std_ex`` on a class which is its own ancestor Close 2680 * Added a new check that warns the user if a function call is used inside a test but parentheses are missing. Close 2658 * ``len-as-condition`` now only fires when a ``len(x)`` call is made without an explicit comparison The message and description accompanying this checker has been changed reflect this new behavior, by explicitly asking to either rely on the fact that empty sequence are false or to compare the length with a scalar. Close 2684 * Add ``preferred-module`` checker that notify if an import has a replacement module that should be used.
