Are there any advantages > of gdbm over db? Heh. I interpret this question as a suggestive one, suggesting there are none. Well, apart from "more freedom of choice for the user"... But, the question caused me doing 1 step back and review the DBM types again. * gdbm does not allow concurrent reading and writing, which means I have to do a clumsy copy/modify/rename-back cycle for every change to make sure apache2 can continue reading at all times. db does. * gdbm feels less bloated with complexity, options etc for a simple use case of just having a single list of some 10s of thousands users and passwords. But, basic minimal functionality needed to handle a single-file db with some keys and values is actually as easy in python with bsddb3 as it is with gdbm. * gdbm has worse behaviour regarding crash consistency Ok... I'm still interested in your view about the advantages of preventing users from using gdbm by not providing it as a choice, but besides that, I think I'm going to do see about switching to db instead of gdbm. It's especially the clumsy copy behaviour that I'd be happy about to eliminate. -- Hans van Kranenburg
