New submission from Armin Ronacher armin.ronac...@active-4.com:
Another case of improper locking in logging. The stopListening() method of the
logging config acquires the logging lock, but it doesn't do it early enough.
In order for this function to be thread safe it would have to lock before the
if.
Currently that lock used is useless because it locks assigning to a single
attribute assignment and a global assignment that is never checked to existence
besides the stopListening() function.
The attached patch proposes moving the lock before the if to make it
threadsafe, but in all fairness sake that method is probably never executed
from more than one thread.
