Uhh.... Proper databases don't HAVE non-atomic operations. That's kinda their job. Unless you mean that there's a non-atomic operation that consists of placing some kind of "claim" on a URL and then going and downloading it, and finally reporting completion, but that's easily enough handled by simply ensuring that there are no downloader processes running, and then clear any incomplete claims. But that's still not corrupting the database. Maybe you've only ever worked with half-baked apologies for database systems? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
