Hello ch, I'd say yes it'll block. As to whether this is a problem I guess it depends on how much writing you do. I break my writing down into sections so, there's time in between transactions for readers to get in and read. WAL mode should work. It used to work for me a number of versions back.

Hello ! Here is a small patch that adds ".dumpdata" for "shell.c" in sqlite3. This command should behave exactly like ".dump" but without the database schema. I 'm giving it with the same license as sqlite. Cheers !

Sorry to bother folks with this. We're getting some pushback from our lawyers suggesting that SQLite's use of RC4 even just to generate random numbers is, in their minds, encryption for export purposes. Now, this makes absolutely no sense to me, I can assure you, and I am not finding anything
