`BadDependencyError` when assigning an inherited classmethod to a variable #1840

Open Avasam opened 1 week ago

See https://github.com/python/typeshed/pull/12991/files#diff-75dfb84f0ad6ea28f6880f12c95f276b475cd3f908f0efaaee59217a16de05a3L57-R60 Permalink: https://github.com/Avasam/typeshed/blob/063be1660a9589c1c07fb6e96af275c822d42789/stubs/setuptools/setuptools/__init__.pyi#L58-L59

Replacing

from .discovery import _Finder
find_packages = _Finder.find
find_namespace_packages = _Finder.find

With

from .discovery import PackageFinder, PEP420PackageFinder
find_packages = PackageFinder.find
find_namespace_packages = PEP420PackageFinder.find

Where those classes are defined as:

class _Finder:
    ALWAYS_EXCLUDE: ClassVar[tuple[str, ...]]
    DEFAULT_EXCLUDE: ClassVar[tuple[str, ...]]
    @classmethod
    def find(cls, where: StrPath = ".", exclude: Iterable[str] = (), include: Iterable[str] = ("*",)) -> list[str]: ...

class PackageFinder(_Finder):
    ALWAYS_EXCLUDE: ClassVar[tuple[str, ...]]

class PEP420PackageFinder(PackageFinder): ...
