New submission from Bar Harel <[email protected]>:
Quick and small fix.
os.PathLike.__subclasshook__ does not check if cls is PathLike as abstract
classes should.
This in turn causes this bug:
class A(PathLike):
pass
class B:
def __fspath__(self):
pass
assert issubclass(B, A)
I will fix the bug later today and push a patch over to python/cpython on
GitHub.
