[New-bugs-announce] [issue7980] time.strptime not thread safe

Willard report at bugs.python.org

New submission from Willard <cptnwillard at gmail.com>:

The following script raises several "_strptime_time" AttributeErrors (on OS X 10.4 at least).

If time.strptime is used before starting the threads, then no exception is raised (the issue may thus come from strptime.py not being imported in a thread safe manner).

import time
import thread

def f():
    for m in xrange(1, 13):
        for d in xrange(1,29):

for _ in xrange(10):
    thread.start_new_thread(f, ())

> Traceback (most recent call last):
>   File "[...]/test.py", line 75, in f
>     time.strptime("2010%02d%02d"%(m,d),"%Y%m%d")
> AttributeError: _strptime_time
