After some offline discussion, this appears to probably be the case. sqlite opens the db file O_RDONLY, and attempts to acquire an fcntl F_WRLCK on it, to which it gets EROFS back. Trying to acquire a writelock on a file opened readonly doesn't make a lot of sense to me; can someone tell me if POSIX specifies that that should fail? In any case, I think technically fcntl should be returning EBADF here, not EROFS (I think this is our fault, but I haven't checked yet). I don't know if it makes a difference what error code sqlite gets back; I'll try later to see if it does anything differently when it gets EBADF back instead. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
