pylint exceeds max recursion depth with setuptools.Command

[laplante-sean]

This does not appear to be fixed on the preview release. I'm testing on a Windows 10 machine.

Winver: Version 1903 (OS Build 18362.356)

Steps to reproduce

1. python -m venv .\venv
2. .\venv\Scripts\activate.ps1
3. pip install pylint
4. pylint recurse_setup.py

recurse_setup.py

from setuptools import setup, find_packages, Command

class AnyCommand(Command):
    def initialize_options(self):
        pass
    def finalize_options(self):
        pass
    def run(self):
        print("Do anything")

setup(
    name='Thing',
    version='1.0',
    packages=find_packages(),
    cmdclass={
        'anycommand': AnyCommand
    },
)

The exception does not happen if you remove the AnyCommand from recurse_setup.py

works_setup.py

from setuptools import setup, find_packages

setup(
    name='Thing',
    version='1.0',
    packages=find_packages()
)

Current behavior

I didn't want to paste the entire error because it repeats and is crazy long:

Thanks for opening an issue! It's something we want to fix in a future bug fix release.
