Bug description:
This came up in python/typeshed#11310: When passing an empty sequence to commonpath()
, a ValueError
is raised with an appropriate error message. When an "empty" iterable is passed, an IndexError
is raised instead, although iterables otherwise work fine:
from posixpath import commonpath
commonpath([]) # -> ValueError: commonpath() arg is an empty sequence
commonpath(iter([])) # -> IndexError: tuple index out of range
The fix is trivial, I'll send a PR. Technically this is an API change, though, although the old API is unexpected.
