Comment:
This is still an issue for us, but we were able to find a workaround I
wanted to share:
1. The problem is related to using threads that access the database inside
a TransactionTestCase
2. Explicitly closing database connections before the threads exit seems
to resolve the issue
We are using the following decorator:
{{{
def close_db_connections(func, *args, **kwargs):
"""
Decorator to close db connections during threaded execution
Note this is necessary to work around:
https://code.djangoproject.com/ticket/22420
"""
def _inner(*args, **kwargs):
func(*args, **kwargs)
for conn in connections.all():
conn.close()
return _inner
}}}
At first blush, it seems like TransactionTestCase may not be threadsafe.
While I'd love to work on a minimal example of the broken behavior, I
don't have time. :(
Hopefully this workaround is helpful to others who may run across this
problem. Re-opening in case someone wants to take some action.
