[New-bugs-announce] [issue14787] pkgutil.walk_packages returns extra modules

[Chris Jerdonek]

New submission from Chris Jerdonek <chris.jerdonek at gmail.com>:

pkgutil.walk_packages(paths) seems to return incorrect results when the name of a subpackage of a path in paths matches the name of a package in the standard library.  It both excludes modules it should include, and includes modules it should exclude.  Here is an example:

> mkdir temp
> touch temp/__init__.py
> touch temp/foo.py
> mkdir temp/logging
> touch temp/logging/__init__.py
> touch temp/logging/bar.py
> python
Python 3.2.3 (default, Apr 29 2012, 01:19:06) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>> from pkgutil import walk_packages
>>> for info in walk_packages(['temp']):
...   print(info[1], info[0].path)
... 
foo temp
logging temp
logging.config /opt/local/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/logging
logging.handlers /opt/local/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/logging
>>> 

Observe that logging.bar is absent from the list, and logging.config and  logging.handlers are included.
