This is an annoying issue to look at, because shutil.chown has (for our purposes) three signatures:
This is a really difficult thing to guarantee from our code. We more or less depend on being able to pass two parameters of
None | int | str
, and it working. In our only caller we do ensure that at least one of the variables is not None, but convincing mypy of this is more work than it's worth.This issue only shows up in CI with python >= 3.13. It also shows up with pyright (used in VSCode) for earlier versions because of an updated typeshed.
