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
and contextmanager-generator-missing-cleanup
), performance improvements, and an astroid
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 that Github can use to automatically annotate code. Use it withpylint --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
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 now done once per file instead of once for each token.Refs #9608.
v3.1.1
What's new in Pylint 3.1.1?
Release date: 2024-05-13
False Positives Fixed
-
Treat
attrs.define
andattrs.frozen
as dataclass decorators intoo-few-public-methods
check.Closes #9345
-
Fix a false positive with
singledispatchmethod-function
when a method is decorated with bothfunctools.singledispatchmethod
andstaticmethod
.Closes #9531
-
Fix a false positive for
consider-using-dict-items
when iterating usingkeys()
and then deleting an item using the key as a lookup.Closes #9554
v3.1.0
Two new checks--use-yield-from
, deprecated-attribute
-- and a smattering of bug fixes.
New Features
-
Skip
consider-using-join
check for non-empty separators if ansuggest-join-with-non-empty-separator
option is set tono
.Closes #8701
-
Discover
.pyi
files when linting.These can be ignored with the
ignore-patterns
setting.Closes #9097
-
Check
TypeAlias
andTypeVar
(PEP 695) nodes forinvalid-name
.Refs #9196
-
Support for resolving external toml files named pylintrc.toml and .pylintrc.toml.
Closes #9228
-
Check for
.clear
,.discard
,.pop
andremove
methods being called on a set while it is being iterated over.Closes #9334
New Checks
-
New message
use-yield-from
added to the refactoring checker. This message is emitted when yielding from a loop can be replaced byyield from
.Closes #9229.
-
Added a
deprecated-attribute
message to check deprecated attributes in the stdlib.Closes #8855
False Positives Fixed
-
Fixed false positive for
inherit-non-class
for generic Protocols.Closes #9106
-
Exempt
TypedDict
fromtyping_extensions
fromtoo-many-ancestor
checks.Refs #9167
False Negatives Fixed
-
Extend broad-exception-raised and broad-exception-caught to except*.
Closes #8827
-
Fix a false-negative for unnecessary if blocks using a different than expected ordering of arguments.
Closes #8947.
Other Bug Fixes
-
Improve the message provided for wrong-import-order check. Instead of the import statement ("import x"), the message now specifies the import that is out of order and which imports should come after it. As reported in the issue, this is particularly helpful if there are multiple imports on a single line that do not follow the PEP8 convention.
The message will report imports as follows: For "import X", it will report "(standard/third party/first party/local) import X" For "import X.Y" and "from X import Y", it will report "(standard/third party/first party/local) import X.Y" The import category is specified to provide explanation as to why pylint has issued the message and guidence to the developer on how to fix the problem.
Closes #8808
Other Changes
-
Print how many files were checked in verbose mode.
Closes #8935
-
Fix a crash when an enum class which is also decorated with a
dataclasses.dataclass
decorator is defined.Closes #9100
Internal Changes
-
Update astroid version to 3.1.0.

block paired withelse: continue
.Closes #6804
-

no-member
involving function attributes supplied by decorators.Closes #9246
-

Closes #9307
-

block when assignments took place in both thetry
block and each exception handler.Closes #9451
Other Bug Fixes
-
Catch incorrect ValueError
"generator already executing"
for Python 3.12.0 - 3.12.2. This is fixed upstream in Python 3.12.3.Closes #9138
v3.0.3
What's new in Pylint 3.0.3?
Release date: 2023-12-11
False Positives Fixed
-
Fixed false positive for
unnecessary-lambda
when the call has keyword arguments but not the lambda.Closes #9148
-
Fixed incorrect suggestion for shallow copy in unnecessary-comprehension
Example of the suggestion: #pylint: disable=missing-module-docstring a = [1, 2, 3] b = [x for x in a] b[0] = 0 print(a) # [1, 2, 3]
After changing b = [x for x in a] to b = a based on the suggestion, the script now prints [0, 2, 3]. The correct suggestion should be use list(a) to preserve the original behavior.
Closes #9172
-
Fix false positives for
undefined-variable
andunused-argument
for classes and functions using Python 3.12 generic type syntax.Closes #9193
