Hi,
I have my whitelist "automagically" set up, i.e.
CONFIRM_APPEND = os.path.expanduser("~/.tmda/lists/whitelist_confirmed")
My understanding of qmail is that there are no guarantees on serialization.
If two cofirmation e-mails arrive close to each other in time, there is no
guarantee that the two processes running won't try to append to the
whitelist at the same time.
How is synchronization (i.e. writing collisions on the file) handled? Is
the "append" guaranteed atomic?
Immediately after this, I'm gonna go digging in the Python scripts.
Thanks a lot for any file serialization or process synchronization info.
Dave.
