Bumps pylint from 2.17.7 to 4.0.9
in /examples/bzlmod and replaces pylint-print with
pylint-per-file-ignores.

pylint-print 1.0.1 is incompatible with Pylint 4.0+ due to the removal
of IAstroidChecker from pylint.interfaces. Replace it with
pylint-per-file-ignores in examples/bzlmod to demonstrate plugin
loading via py_console_script_binary(deps = [...]), and update
entry_points tests and documentation accordingly.

Release notes

Sourced from pylint's releases.

v4.0.9

What's new in Pylint 4.0.9?

Release date: 2026-09-23

Security Fixes

• Someone without access to the configuration or linted code, but with access to the cache directory (predictable PYLINT_HOME on a multi-user host) can no longer write a crafted pickle that will runs arbitrary code when pylint access its stat cache. The result cache is now stored as JSON instead of pickle, preventing code-execution. The workaround is upgrading or not pointing PYLINT_HOME to an untrusted, shared, or group-writable directory. The default value, ~/.cache/pylint, is writable only by the user running pylint. (CVE with the same information pending)

False Positives Fixed

• Fixed a false positive for no-self-use on a method that only uses self before a locally defined class (or other nested method), because the checker's could-be-a-function tracking state was not restored after visiting the nested method.

  Closes #3705

• Fix a false positive for :ref:not-callable when calling functions constructed with types.FunctionType or types.LambdaType.

  Closes #7500

• Fix a false positive for unnecessary-direct-lambda-call when a directly called lambda in a class body wraps a comprehension containing an assignment expression. PEP 572 makes that a SyntaxError without the lambda's scope, so following the message produced code that would not compile.

  Closes #9294

• Fix a false positive for :ref:unnecessary-ellipsis when an ellipsis is the sole body statement of a method defined on a Protocol.

  Closes #9319

• Fix a false positive for :ref:bad-exception-cause when the bases of the class being raised from cannot be inferred, such as an exception deriving from a C extension class. :ref:raising-non-exception and :ref:catching-non-exception already guard the same inherit_from_std_ex
