Hi all,
I have an interesting problem:
I have written code, that reads a logfile and parses it for date string
(Thu Jun 29 14:01:23 2006).
Standalone everthing works fine, all is recognized.
But if I let the same code run in a thread, with the same file as input
I get the following error:
....
File "sensor.py", line 158, in gotData
t = time.strptime(s)
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=Thu Jun 29 14:01:23
2006 fmt=%a %b %d %H:%M:%S %Y
Has anyone encountered similiar problems? And how did you get around?
Thanks,
Maximilian

do you read the logfile in the thread too or pass the read that to the

Possibilities:
(1) The thread implementation has acquired extra characters (whitespace
or \x00).
(2) The thread implementation has changed to a locale that doesn't have
"Thu" & "Jun" as day/month name abbreviations.
Try inserting
print "strptime(%r); locale: %r" % (s, locale.getlocale())
before your call to strptime()

The parsing thread reads also the file from the disk.

Thank you so much!
(2) was the reason!
Without threads, locale.getlocale() returns (None, None), while calling
it in this thread gives back ('de_DE', 'iso-8859-15').
I'm still curious, why this occurs, but anyway it's fixable with
setlocale(LC_ALL, 'C'); so normally Python doesn't set locales
according to my system environment, but in a separate thread it does...
strange (or i just didn't set something correctly?).
Thank you so much!
