[New-bugs-announce] [issue14698] test_posix failures - getpwduid()/initgroups()/getgroups()

[Charles-François Natali]

New submission from Charles-François Natali <neologix at free.fr>:

test_posix is consistently failing on the bigmem buildbot:

http://python.org/dev/buildbot/all/builders/AMD64 debian bigmem 3.x/builds/291/steps/test/logs/stdio

"""
======================================================================

KeyError: 'getpwuid(): uid not found: 5025'
"""

I assume that's because the buildbot tests run with a UID without any corresponding pwd entry (which is legit).
The attached patch should fix thoe failures, by making the tests more robust.
