15 check-ins using file src/os_unix.c version 2ce91d5d

2010-05-06
18:27
If recovery is run before a checkpoint, change back to a CHECKPOINT lock before performing the actual checkpoint. (check-in: dc98ee16 user: dan tags: trunk)
18:04
Only pass -1 as the size parameter to xShmGet when the caller does not care what size mapping is returned. Only call xShmSize when the underlying allocation (not the mapping) should be resized. (check-in: 637f51dd user: dan tags: trunk)
17:28
Fix a bug whereby an old snapshot could be checkpointed (and subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header. (check-in: d0c0034b user: dan tags: trunk)
16:06
After throwing an error to say that one cannot change into WAL mode within a tranactions, do not then go and change into WAL mode. (check-in: 56a17dae user: drh tags: trunk)
15:56
Further coverage tests. (check-in: 98a9713e user: dan tags: trunk)
15:36
Update configure scripts for WAL support. (check-in: 2edc5129 user: shaneh tags: trunk)
14:42
Add tests to cover a couple of branches in wal.c. (check-in: 429f437f user: dan tags: trunk)
13:36
Unset a tcl variable before reusing it in wal.test. (check-in: e83efb23 user: dan tags: trunk)
12:15
Add tests for some lock-contention cases. (check-in: f0fcb9c9 user: dan tags: trunk)
11:56
Remove the noop-mutex implementations of mutex_held() and mutex_notheld() since they are both unreachable. (check-in: 6767b62a user: drh tags: trunk)
11:55
Add two text files containing pager design notes to the doc/ subfolder. (check-in: ed817fc8 user: drh tags: trunk)
11:32
Add test cases to test the libraries handling of corrupt wal-index headers. (check-in: 9465b267 user: dan tags: trunk)
07:43
Add tests for handling errors returned by xShm VFS methods. (check-in: fbbcacb1 user: dan tags: trunk)

20:00
Change the behavior of the sqlite3_wal_hook() callback. It should now return SQLITE_OK or an error code and the error code is propagated back up the stack. If a checkpoint is desired, the callback should invoke sqlite3_wal_callback() itself. (check-in: 1b14195e user: drh tags: trunk)
19:09
Further simplifications to the SHM locking logic. Remove the SQLITE_SHM_QUERY option. Unify the WRITE to READ and RECOVER to READ transitions. (check-in: e9bfa6e4 user: drh tags: trunk)
