New submission from James Pickering <[email protected]>:
If you run pkgutil.iter_zipimport_modules with a prefix parameter, and the
module in question is a package, then the prefix parameter is ignored.
The most visible symptom of this is when running pkgutil.walk_packages for a
zipfile. Imagine we have a module structure like this (or create one):
a/
a/__init__.py
a/b/
a/b/__init.__py
If we put this structure in a directory, add the directory to sys.path, and run
pkgutil.walk_packages(), it will find modules "a" and "a.b".
If we put this structure in a zipfile, however, we add this file to sys.path,
and run pkgutil.walk_packages(), it will find modules "a" and "b". This is
because pkgutil.iter_zipimport_modules ignores the prefix parameter "a.".
This is incorrect.
This can be fixed by changing line ~344 of Lib/pkgutil.py from:
yield fn[0], True
to
yield prefix + fn[0], True
Thanks, James
P.s, This is my first Python bug report. I apologise in advance for any poor
etiquette.
