Fix a false positive for invalid-name when a module-level variable is assigned
an instance of a TypedDict subclass. Such a name is a value, not a type
definition, so it is now checked against the constant or variable regex instead
of class-rgx.
Fix a crash in the not-context-manager and not-async-context-manager
checks when the context manager infers to a value without a name, such as the slice returned by with slice(...) / async with slice(...).
Fix a false positive for nested-min-max (W3301) when the inner min/max call carries a keyword argument such as key=. Flattening the call dropped the keyword and changed the result, so nested calls whose inner call has keyword arguments are no longer flagged.
Fix a false suggestion from nested-min-max (W3301): when rewriting a nested min/max into a splat call, arguments positioned after the splatted call were silently dropped, so the suggested code changed the result.
Fix a false positive for too-many-locals (R0914): PEP 695 type parameters, i.e. the T1 and T2 in a generic def f[T1, T2] signature, were counted as local variables. They are type-system constructs, not runtime locals, and are now excluded from the local-variable count.
Fix literal-comparison (R0123) emitting a corrupted suggestion for identifiers
that contain is (e.g. axis is 5 was rendered ax== == 5). The suggestion
is now rebuilt from the operands and operator.
Fix false positives in bad-string-format-type (E1307) for valid % formatting: %i/%u applied to a float (both truncate like %d) and %a applied to any
non-int type (%a is type-agnostic like %s/%r).
too-many-lines could be reported at the line of a # pylint: disable=too-many-lines
pragma found in a previously linted module. Pragma positions are now reset between
modules, so the message is reported at line 1 (or at the current module's own pragma)
regardless of which files were linted before.
Coverage variation is the difference between the coverage for the head and common ancestor commits of the pull request branch: <coverage of head commit> - <coverage of common ancestor commit>
Diff coverage is the percentage of lines that are covered by tests out of the coverable lines that the pull request added or modified: <covered lines added or modified>/<coverable lines added or modified> * 100%
