[issue20220] TarFile.list() outputs wrong time

2014-12-06 Thread David Edelsohn 

David Edelsohn added the comment:

There now are two zLinux buildbots: zlinux (running SUSE) and zwheezy (running 
Debian).  zlinux (running on SUSE) has the libc problem causing the timezone 
error.  A second buildbot was added, not converting or upgrading the existing 
buildbot.

I still would appreciate the patch from Issue22844 to fix the test_gdb failure 
on the zwheezy buildbot.

Antoine Pitrou added the comment:

 Any other ideas for a reliable method to restore the correct timezone after 
 running a test?

No. The best would be for you to investigate. Perhaps contact some glibc guys.

David Edelsohn added the comment:

It doesn't fail on the Debian system.  The Debian system will be successful 
after the test_gdb patch is installed.

May be issue6478 is related.

I'm not sure. issue6478 looks like a Python stdlib bug, while this issue looks 
like a libc problem.

David, could you try the patch in msg230703 and see if it fixes the problem on 
your buildbot?

David Edelsohn added the comment:

Unfortunately, the patch does not fix the failures of running test_imaplib 
before test_tarfile or test_datetime.

I can reproduce under Linux using:

2014-11-05 Thread Antoine Pitrou 

Antoine Pitrou added the comment:

We seem to be bitten by the following bit of glibc (?) oddity:

 os.environ['TZ'] = 'America/New_York'
 time.tzset()
 time.daylight, time.timezone, time.altzone, time.tzname
(1, 18000, 14400, ('EST', 'EDT'))
 os.environ['TZ'] = 'STD-1DST'
 time.tzset()
 time.daylight, time.timezone, time.altzone, time.tzname
(1, -3600, -7200, ('STD', 'DST'))
 os.environ['TZ'] = 'America/New_York'
 time.tzset()
 time.daylight, time.timezone, time.altzone, time.tzname
(1, -3600, -7200, ('STD', 'DST'))
