v3.2.1

What's new in Pylint 3.2.1?

Release date: 2024-05-18

False Positives Fixed

• Exclude if/else branches containing terminating functions (e.g. sys.exit())
  from possibly-used-before-assignment checks.

  Closes #9627

• Don't emit typevar-name-incorrect-variance warnings for PEP 695 style TypeVars.
  The variance is inferred automatically by the type checker.
  Adding _co or _contra suffix can help to reason about TypeVar.

  Refs #9638

• Fix a false positive for possibly-used-before-assignment when using
  typing.assert_never() (3.11+) to indicate exhaustiveness.

  Closes #9643

Other Bug Fixes

• Fix a false negative for --ignore-patterns when the directory to be linted is specified using a dot(.) and all files are ignored instead of only the files whose name begin with a dot.

  Closes #9273

• Restore "errors / warnings by module" section to report output (with -ry).

  Closes #9145

• trailing-comma-tuple should now be correctly emitted when it was disabled globally
  but enabled via local message control, after removal of an over-optimisation.

  Refs #9608

• Add --prefer-stubs=yes option to opt-in to the astroid 3.2 feature
  that prefers .pyi stubs over same-named .py files. This has the
  potential to reduce no-member errors but at the cost of more errors
  such 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 RecursionError
  and also makes the prefer .pyi stubs feature in astroid 3.2.0 opt-in
  with the aforementioned --prefer-stubs=y option.
