Fix false positives for
undefined-variable
for classes using Python 3.12generic type syntax.
Closes #9335

Closes #9947
v3.3.0
Compare Source
Release date: 2024-09-20
Changes requiring user actions
We migrated
symilar
to argparse, from getopt, so the error and help output changed(for the better). We exit with 2 instead of sometime 1, sometime 2. The error output
is not captured by the runner anymore. It's not possible to use a value for the
boolean options anymore (
--ignore-comments 1
should become--ignore-comments
).Refs #9731
New Features
Add new
declare-non-slot
error which reports when a class has a__slots__
member and a type hint on the class is not present in__slots__
.Refs #9499
New Checks
Added
too-many-positional-arguments
to allow distinguishing the configuration for too manytotal arguments (with keyword-only params specified after
*
) from the configurationfor too many positional-or-keyword or positional-only arguments.
As part of evaluating whether this check makes sense for your project, ensure you
adjust the value of
--max-positional-arguments
.Closes #9099
Add
using-exception-groups-in-unsupported-version
andusing-generic-type-syntax-in-unsupported-version
for uses of Python 3.11+ or3.12+ features on lower supported versions provided with
--py-version
.Closes #9791
Add
using-assignment-expression-in-unsupported-version
for uses of:=
(walrus operator)on Python versions below 3.8 provided with
--py-version
.Closes #9820
Add
using-positional-only-args-in-unsupported-version
for uses of positional-only args onPython versions below 3.8 provided with
--py-version
.Closes #9823
Add
unnecessary-default-type-args
to thetyping
extension to detect the useof unnecessary default type args for
typing.Generator
andtyping.AsyncGenerator
.Refs #9938
False Negatives Fixed
Fix computation of never-returning function:
Never
is handled in addition toNoReturn
, and priority is given to the explicit--never-returning-functions
option.Closes #7565.
Fix a false negative for
await-outside-async
when await is inside Lambda.Refs #9653
Fix a false negative for
duplicate-argument-name
by includingpositional-only
,*args
and**kwargs
arguments in the check.Closes #9669
Fix false negative for
multiple-statements
when multiple statements are present onelse
andfinally
lines oftry
.Refs #9759
Fix false negatives when
isinstance
does not have exactly two arguments.pylint now emits a
too-many-function-args
orno-value-for-parameter
appropriately for
isinstance
calls.Closes #9847
Other Bug Fixes
--enable
with--disable=all
now produces an error, when an unknown msg code is used. Internalpylint
messages are no longer affected by--disable=all
.Closes #9403
Impossible to compile regexes for paths in the configuration or argument given to pylint won't crash anymore but
raise an argparse error and display the error message from
re.compile
instead.Closes #9680
Fix a bug where a
tox.ini
file with pylint configuration was ignored and it exists in the current directory..cfg
and.ini
files containing aPylint
configuration may now use a section named[pylint]
. This enhancement impacts the scenario where these file types are used as defaults when they are present and have not been explicitly referred to, using the--rcfile
option.Closes #9727
Improve file discovery for directories that are not python packages.
Closes #9764
Other Changes
Remove support for launching pylint with Python 3.8.
Code that supports Python 3.8 can still be linted with the
--py-version=3.8
setting.Refs #9774
Add support for Python 3.13.
Refs #9852
Internal Changes
All variables, classes, functions and file names containing the word 'similar', when it was,
in fact, referring to 'symilar' (the standalone program for the duplicate-code check) were renamed
to 'symilar'.
Closes #9734
Remove old-style classes (Python 2) code and remove check for new-style class since everything is new-style in Python 3. Updated doc for exception checker to remove reference to new style class.

Don't emit

Add
--prefer-stubs=yes
option to opt-in to the astroid 3.2 featurethat prefers
.pyi
stubs over same-named.py
files. This has thepotential to reduce
no-member
errors but at the cost of more errorssuch as
not-an-iterable
from function bodies appearing as...
.Defaults to
no
.Closes #9626
Closes #9623
Internal Changes
Update astroid version to 3.2.1. This solves some reports of

--prefer-stubs=y
option.Refs #9139
v3.2.0

What's new in Pylint 3.2.0?
Release date: 2024-05-14
Of note: a
github
reporter, two new checks (possibly-used-before-assignment
andcontextmanager-generator-missing-cleanup
), performance improvements, and anastroid
upgrade providing support for@overload
and.pyi
stubs.New Features
Understand
six.PY2
andsix.PY3
for conditional imports.Closes #3501
A new
github
reporter has been added. This reporter returns the output ofpylint
in a format thatGithub can use to automatically annotate code. Use it with
pylint --output-format=github
on your Github Workflows.Closes #9443.
New Checks
Add check
possibly-used-before-assignment
when relying on names after anif/else
switch when one branch failed to define the name, raise, or return.
Closes #1727
Checks for generators that use contextmanagers that don't handle cleanup properly.
Is meant to raise visibilty on the case that a generator is not fully exhausted and the contextmanager is not cleaned up properly.
A contextmanager must yield a non-constant value and not handle cleanup for GeneratorExit.
The using generator must attempt to use the yielded context value
with x() as y
and not justwith x()
.Closes #2832
False Negatives Fixed
If and Try nodes are now checked for useless return statements as well.
Closes #9449.
Fix false negative for
property-with-parameters
in the case of parameters which arepositional-only
,keyword-only
,variadic positional
orvariadic keyword
.Closes #9584
False Positives Fixed
pylint now understands the
@overload
decorator return values better.Closes #4696
Refs #9606
Performance Improvements
Ignored modules are now not checked at all, instead of being checked and then
ignored. This should speed up the analysis of large codebases which have
ignored modules.
Closes #9442
ImportChecker's logic has been modified to avoid context files when possible. This makes it possible
to cache module searches on astroid and reduce execution times.
Refs #9310.
An internal check for
trailing-comma-tuple
being enabled for a file or not is nowdone once per file instead of once for each token.
Refs #9608.
