New submission from Gregory P. Smith:
test_posix.test_getgrouplist is failing for me on my Linux (ubuntu precise)
based desktop at work.
It looks like posix.getgrouplist() is returning all of the larger GIDs. The
lowest one it is reporting for my user is 499 but the more distro specific
groups that I am are not included in its 18 element long list it returns so the
test fails:
test test_posix failed -- Traceback (most recent call last):
File "cpython/default/Lib/test/test_posix.py", line 660, in test_getgrouplist
pwd.getpwuid(os.getuid())[3])))
AssertionError: Items in the first set but not the second:
128
4
104
44
46
20

25
strace reveals that the 'id -G' command this test is trying to compare against
calls getgroups() while posix.getgrouplist() appears to do something else that
does not make that syscall.
posix.getgroups() does the same thing as 'id -G', this test for
posix.getgrouplist(username, uid) is making an incorrect assertion.
