Solaris 10's id(1M) does not support the "-G" option, so we get the following:
% ./python -m test test_posix 
[1/1] test_posix
id: illegal option -- G
Usage: id [-ap] [user]
1 test OK.
The code already tests that id -G (std) output, and assumes that id -G is not supported if the output is empty. 
QUESTION: Does the user compiling the code need to see the stderr output of id? After all the test is correctly skipped.
Fix:
% diff ./Lib/test/test_posix.py.FCS ./Lib/test/test_posix.py
378c378
< with os.popen('id -G') as idg:
---
> with os.popen('id -G 2> /dev/null') as idg:
Consideration: Lib/platform.py has introduced DEV_NULL but it does not seem to be used in other code or tests (beside platform.py).
Regards,
Peter

The correct spelling of that is os.devnull. platform.DEV_NULL exists only for backwards compatibility (not sure platform.py still has standalone releases). It is not documented and only used internally. For a POSIX-only test like this one, hard-coding /dev/null is the simplest thing that works.
Thanks for the patch; our Mac experts will get to it. Please generate unified diffs in the future.

(Oops, this is for Solaris, not Mac. I’m always confused about those funny OSes.)

Can our Solaris gurus take this on please.

I never saw this because I use GNU 'id' on my Solaris 10 machines. Taking care of this. Thanks for the report and the persistence :-)
