Bug Description

This is a script running on drescher to help us processing sync bugs in bulk.

Drescher has Python 2.4.3 (dapper), locale "C", and I am using p-lp-bugs main bzr head (r61) plus the recent patch in bug 188018. My cookie uses edge.launchpad.net.

When the script tries to access Bug(187804).reporter, I get:

  File "/home/lp_archive/bin/syncbugbot", line 56, in ?
    main()
  File "/home/lp_archive/bin/syncbugbot", line 49, in main
    process_bug(int(fields[0]), fields[1:], failed)
  File "/home/lp_archive/bin/syncbugbot", line 29, in process_bug
    print 'processing bug %i, package %s, reporter %s...' % (bug, task.sourcepackage, b.reporter)
  File "/home/lp_archive/python/launchpadbugs/lphelper.py", line 255, in <lambda>
    if fget : fget = lambda s, n=fget.__name__ : getattr(s, n)()
  File "/home/lp_archive/python/launchpadbugs/html_bug.py", line 87, in func
    x.parse()
  File "/home/lp_archive/python/launchpadbugs/html_bug.py", line 470, in parse
    self.date = LPTime(d[0].prop("title"))
  File "/home/lp_archive/python/launchpadbugs/lptime.py", line 59, in __new__
    raise ValueError, "Unknown date format (%s)" %time_str
ValueError: Unknown date format (2008-01-31 20:15:11 CET)

This also happens with other bugs (e. g. 186856)

This command works as expected on current hardy with the hardy python-launchpad-bugs package, as well as with bzr main head (PYTHONPATH=/tmp/main/):

$ python -c "import launchpadbugs.connector as Connector; Bug = Connector.ConnectBug(); Bug.authentication = '/home/pitti/.lpcookie'; print Bug(186856).reporter"

It even works in my dapper chroot with LC_ALL=C. Thus, at the moment I'm a bit unsure what is different on drescher (our server where that sync script runs).

I augmented lptime.py with some debugging output:

        for i in conv_functions:
            try:
                print 'trying conv_function %s on %s' % (str(i), time_str)
                t = i(time_str)
                print 'success!'
                break
            except (ValueError, TypeError), e:
                print 'fail:', e
                continue
        else:
            raise ValueError, "Unknown date format (%s)" %time_str

on my workstation:

on drescher:

fail: unconverted data remains: 00:39:09 CET

Thus I tried the strptime() call in convert_html_time() directly:

>>> print time.strptime("2008-01-29 00:39:09 CET", "%Y-%m-%d %H:%M:%S %Z")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.4/_strptime.py", line 293, in strptime
    raise ValueError("time data did not match format: data=%s fmt=%s" %
ValueError: time data did not match format: data=2008-01-29 00:39:09 CET fmt=%Y-%m-%d %H:%M:%S %Z

Thus this is clearly an installation problem on drescher, not a p-lp-bug any more. Sorry for the noise.
