@Pierre-Sassoulas @jacobtylerwalls Anything that could explain this regression?

[Pierre-Sassoulas]

I have no idea this is pretty surprising to me, but the number of thumbsups doesn't lie. I suggest bissecting using a reproducer to find the culprit, I wasn't able to look into it yet.

[correctmost]

I was able to reproduce the issue with this folder structure:

.
├── __init__.py
├── a.py
├── migrations
│   ├── __init__.py
│   └── a.py
└── pyproject.toml

a.py

# pass

migrations/a.py

x

pyproject.toml

[tool.pylint.main]
ignore = "migrations"

The bisection led to commit abb8187.

@temyurchenko would you have any availability to look into this?
