Hi Everyone, Does anyone know if this page is still up to date with respect to when you get "SQLITE_LOCKED" when operating in shared cache mode ? http://www.sqlite.org/cvstrac/wiki?p=DatabaseIsLocked
(I'm trying to solve a two writers problem and am trying to understand the best way to solve it) (and I think part of my problem is not understanding the difference between 'locked' and 'busy' ) I've seen the notify example here. http://www.sqlite.org/unlock_notify.html and a 'busy' example here http://www.sqlite.org/cvstrac/wiki?p=MultiThreading http://www.sqlite.org/cvstrac/wiki?p=SampleCode Is it possible for something to be 'locked' then after being unlocked at it tries again it gets 'busy' ? Should my re-try strategy be the same or different for 'busy' and 'locked'.... and I guess if I get SQLITE_IOERR_BLOCKED (http://www.sqlite.org/c3ref/busy_handler.html) I should always back off and wait a while ? Any tips for the 'best' way to tackle this gratefully received. (I have one thread writing a lot but it can block for a 'long' time and still be ok (up to 5 seconds) - and another one mostly reading and doing a few occasional writes, but it can't block for long (>250ms) because it's servicing the UI and repainting will stop.) many thanks Owen _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
