SQLite seems to be solid in handling short read/write among many advantages it has. My emulation of short read/write was done against sqlite databases during tests, and I have not seen problems caused by them if I am not mistaken. SQLite library handles the necessary additional reads automagically. > Advantage is that Firefox/Thunderbird/SeaMonkey can all share the same files Frankly, I have no background to comment on this. But maybe if one needs to add local certificates due to organizational issues, there will be one less additional data base to take care of. So it looks replacing the current code with the new NSS code/backend seems a win in the long run. > ........ > >> However, now that Sleepycat has been bought by Oracle, I am not sure >> what is the good option left. > > I think v5 of Berkeley DB is still under the Sleepycat licence. > Aha, that sounds good. Oracle web page I referred to has a link to v6 code, though. http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index.html If I am not mistaken, it even claims to have SQL interface based on SQLite. I don't know if it is done via talking to a separate engine or even incorporate the SQLite source code inside.
