8.3.8: Support for pylint>=2.13.0 #221

Open seanbickle opened 2 years ago

seanbickle commented 2 years ago

Context

Python version == 3.8.2 Pylama version == 8.3.8 Pylint version >= 2.13.0

Problem

From the Pylint changelog:

When run in parallel mode pylint now pickles the data passed to subprocesses with the dill package. The dill package has therefore been added as a dependency.

Pylint fails to pickle pylint.lint.pylinter.PyLinter.reporter, which is a pylama Reporter object:
