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

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

===========================

* 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

2.5.4

===========================

* 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 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 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

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.

This check is emitted when ``pylint`` finds an imported module that has a
preferred replacement listed in ``preferred-modules``.

* ``assigning-non-slot`` not emitted for classes with unknown base classes.

Close 2807

* ``old-division`` is not emitted for non-Const nodes.

Close 2808

* Added method arguments to the dot writer for pyreverse.

Close 2139

* Support for linting file from stdin.

IDEs may benefit from the support for linting from an in-memory file.

Close 1187

* Added a new check ``class-variable-slots-conflict``

This check is emitted when ``pylint`` finds a class variable that conflicts with a slot
name, which would raise a ``ValueError`` at runtime.

* Added new check: dict-iter-missing-items (E1141)

Close 2761

* Fix issue with pylint name in output of python -m pylint --version

Close 2764

* Relicense logo material under the CC BY-SA 4.0 license.

* Skip ``if`` expressions from f-strings for the ``check_elif`` checker

Close 2816

* C0412 (ungrouped-import) is now compatible with isort.

Close 2806

* Added new extension to detect too much code in a try clause

Close 2877

* ``signature-mutators`` option was added

With this option, users can choose to ignore ``too-many-function-args``, ``unexpected-keyword-arg``,
and ``no-value-for-parameter`` for functions decorated with decorators that change
the signature of a decorated function.

Close 259

* Fixed a pragma comment on its own physical line being ignored when part
of a logical line with the previous physical line.

Close 199

* Fixed false ``undefined-loop-variable`` for a function defined in the loop,
that uses the variable defined in that loop.

Close 202

* Fixed ``unused-argument`` and ``function-redefined`` getting raised for
functions decorated with ``typing.overload``.

Close 1581

* Fixed a false positive with ``consider-using-dict-comprehension`` for constructions that can't be converted to a comprehension

Close 2963

* Added ``__post_init__`` to ``defining-attr-methods`` in order to avoid ``attribute-defined-outside-init`` in dataclasses.

Close 2581

* Changed description of W0199 to use the term 2-item-tuple instead of 2-uple.

* Allow a ``.`` as a prefix for Sphinx name resolution.

* Checkers must now keep a 1 to 1 relationship between "msgid" (ie: C1234) and "symbol" (ie : human-readable-symbol)
* In checkers, an old_names can now be used for multiple new messages and pylint is now a little faster

Caused by 1164. It means if you do a partial old_names for a message definition an exception will tell you that you
must rename the associated identification.

* Allow the choice of f-strings as a valid way of formatting logging strings.

Closes 2395

* Added ``--list-msgs-enabled`` command to list all enabled and disabled messages given the current RC file and command line arguments.
