Dan-
Thanks a lot for the ideas.
I tried the first suggestion, but get an UnboundLocalError, local
variable 'graph' referenced before assignment. Not sure how to fix
this.
I also tried the following:
local_data = threading.local()
local_data.__dict__.setdefault('graph', None)
if not local_data.graph:
local_data.graph = build_graph()
But the graph is still rebuilt every time. This occurs through
mod_python and FastCGI. I guess there is a seperate thread handling
each request, so there is no persistence.
I just wanted to give you an update on what I was trying. Thanks again
for the suggestions. I'll post again when I figure it out.
