[issue19469] Duplicate namespace package portions (but not on Windows)

[Eric Snow]

New submission from Eric Snow:

In changeset 88c3a1a3c2ff you'll find in test_api.py where I threw together a 
__path__ to compare against the one I was getting (which had 2 identical 
entries) on my Ubuntu 12.04 workstation.  The XP buildbot 
(http://buildbot.python.org/all/builders/x86%20XP-4%203.x) took issue with that 
(but non-windows was fine).

I was able to work around the difference (78d36d54391c), but I find the extra 
namespace portions surprising.  I'd like to get to the bottom of it.  I expect 
it has to do with how path entries are done on Windows, or perhaps with the way 
support.temp_cwd() iteracts with sys.path during testing.

Carl Meyer added the comment:

FWIW, this bug has bitten Django; see 
https://code.djangoproject.com/ticket/25246

We can easily work around it for future versions, but we have code in released 
versions that assumed that `__path__` wouldn't contain dupes; it causes us to 
raise an error in a situation that shouldn't be an error (because we need a 
Django "app" module to have exactly one filesystem location).

Brett Cannon added the comment:

I can't reproduce under Python 3.4.3, the 3.4 branch, 3.5 branch, or default 
with a plain namespace package. Can anyone come up with a test case that can 
reproduce this problem? Otherwise I'll assume it was a bug that got fixed in 
3.4.2.

I tried to reproduce it using Python 3.4.3 and 3.4.2. No luck.

OK, if someone finds a way to reproduce the bug in the next week then we will 
keep this open as active, else I'm closing it as out-of-date.
