Description

See two test failures:

======================================================================
ERROR: test_posix_conversion (trac.util.tests.datefmt.PytzTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/tmp/portage/www-apps/trac-1.0.11/work/Trac-1.0.11/trac/util/tests/datefmt.py", line 45, in test_posix_conversion
    tz.utcoffset(None))
AttributeError: 'NoneType' object has no attribute 'utcoffset'

======================================================================
ERROR: test_unicode_input (trac.util.tests.datefmt.PytzTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/tmp/portage/www-apps/trac-1.0.11/work/Trac-1.0.11/trac/util/tests/datefmt.py", line 51, in test_unicode_input
    tz.utcoffset(None))
AttributeError: 'NoneType' object has no attribute 'utcoffset'

----------------------------------------------------------------------

I see them with both 1.0.12 and 1.0.11, but I feel confident I didn't see them with 1.0.11 before (probably around the time it was released).

comment:3 by Jun Omae, 8 years ago

Your installed pytz package is weird. Etc/GMT-4 timezone in pytz is used in those unit cases of 2 failures however it failed to load the timezone. It seems your pytz package doesn't have the timezone.

Environment is Python 2.7.10 running on Gentoo Linux, pytz-2015.6.

comment:5 by Jun Omae, 8 years ago

I investigate with Gentoo on docker. StaticTzInfo class is used for Etc/GMT-4 however DstTzInfo is used on your environment. Etc/GMT-4 must be static timezone, not DST timezone. I consider your pytz is broken.

Milestone: 1.0.13
Resolution: cantfix
Status: closedreopened

Reproduced it with pytz 2016.6 (it seems the version is released on 2016-07-13):

>>> import pytz
>>> pytz.__version__
'2016.6'
>>> tz = pytz.timezone('Etc/GMT-4')
>>> tz
<DstTzInfo 'Etc/GMT-4' GMT-4+4:00:00 STD>
>>> tz.utcoffset(None) is None
True

This issue is filed in https://bugs.launchpad.net/pytz/+bug/1602807.

Workaround is to downgrade to pytz 2016.4.

comment:8 by Jun Omae, 8 years ago

The pytz issue has been fixed and pytz 2016.6.1 is released. See https://pypi.python.org/pypi/pytz/2016.6.1.
