New submission from Eric Snow: In 3987667bf98f pkgutil.find_loader() switched from using pkgutil.iter_importers() to importlib.find_module(). importlib.find_module() checks the module's __loader__ (and raises ImportError when invalid) whereas iter_importers() does no such check. In 3.4 pkgutil.find_loader() switched over to importlib.util.find_spec(), but the same issue remains.
The documentation (and the previous behavior) implies that the ImportError case coming out of find_spec() should result in pkgutil.find_loader() returning None rather than propagating the ImportError. However, it may make more sense to do an explicit check for module.__spec__ before calling find_spec(). ---------- components: Library (Lib) keywords: 3.3regression messages: 216047 nosy: brett.cannon, eric.snow, ncoghlan priority: high severity: normal stage: test needed status: open title: pkgutil.find_loader() raises ImportError instead of returning None type: behavior versions: Python 3.3, Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21211> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
