Priority: 5 Submitted By: Anthony Baxter (anthonybaxter) Assigned to: Anthony Baxter (anthonybaxter) Summary: test_strptime failures on FC2-test

Initial Comment: I'm seeing test_strptime failures on this box, running a version of Fedora Core that's between 1 and the new test release.

test test_strptime failed -- Traceback (most recent call last): File "Lib/test/test_strptime.py", line 258, in test_timezone self.failUnlessEqual(strp_output.tm_isdst, 0) AssertionError: -1 != 0

Note that the following line (which tests GMT) also fails with a -1.

The underlying failure:

-1

Fixed in rev. 1.31 . Basically tweaked the test that checks if time.tzname[0] == time.tzname[1] (which is bad since then you can't tell when DST is in effect or not) to take into acct. if time.tzname[1] (the DST timezone) is set to UTC or GMT. Since there is no adjustment, then just set let be set to 0 through the normal algorithm.

A possible cause for this, Anthony, is having the timezone set to ("UTC", "GMT") and time.daylight to a 1. This would lead to not passing the test since there is an explicit test in the strptime code for when duplicate non-DST and DST timezones are the same and this would do it since UTC and GMT are injected into the non-DST timezone list for comparisons. The default is -1 since you can't tell the proper value if both non-DST and DST are the same. And UTC and GMT should not be considered DST timezones obviously.

Anyway, I hope you don't find anything wrong and it was just a weird glitch in the date settings.

Very very strange. I rebuilt python, and the problem has gone away. I will assign this to myself and try and reproduce it.

Anthony, can you let me know what the following commands spit out?::

import time; import _strptime time.tzname time.daylight _strptime.LocaleTime().timezone _strptime.TimeRE()['Z']

That should be enough info for me to debug this.
