47 check-ins using file src/pragma.c version b9a0a173

2010-05-06
20:19
Make sure to do a clean shutdown of the library upon existing the shell in order to remove WAL files. check-in: c1762dda user: drh tags: trunk
19:55
Exclude all WAL tests from the journaltest permutation. check-in: 46c97d7e user: drh tags: trunk
19:20
Changes to support SQLITE_OMIT_WAL. check-in: 32a8501d user: shaneh tags: trunk
19:04
Updates to the VFS SHM locking documentation. check-in: 9927ce42 user: drh tags: trunk
18:48
Instead of transitioning to RECOVER state from CHECKPOINT when a recovery is required, perform the recovery while holding the CHECKPOINT lock. check-in: bb0b6021 user: dan tags: trunk
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subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header.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
2010-05-05
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
19:04
Test the handling of errors returned by the xShmXXX() APIs. check-in: 72663123 user: dan tags: trunk
18:46
Do not compare page sizes on source and destination of backup until transactions are started and the page sizes are locked. This is a fix to check-in [7bd44794c4]. check-in: ec715778 user: drh tags: trunk
18:20
Simplifications to the SHM locking implementation in os_unix.c. check-in: 9de05bfb user: drh tags: trunk
16:23
Prohibit backup if the destination is using WAL and has a different page size from the source. check-in: 7bd44794 user: drh tags: trunk
15:33
When closing a WAL database, if the exclusive lock on the database file is obtained and the database successfully checkpointed, delete the wal-index file from the file system. check-in: 2ac5d96c user: dan tags: trunk
04:11
Make sure the page size of the main database is fixed following a failed VACUUM attempt. Otherwise, two consecutive failed VACUUM attempts with attempted page_size changes on encrypted or WAL databases could result in database corruption. check-in: 208e7d5d user: drh tags: trunk
03:39
Do not attempt to modify the page_size when running VACUUM on a WAL database. check-in: 58a1a59b user: drh tags: trunk
00:22
Get the previous mutex fix working with SQLITE_DEBUG and with the amalgamation. check-in: df19928f user: drh tags: trunk
00:05
When the in single-threaded mode, the sqlite3_mutex_alloc() interface still returns a non-NULL value. The mutex doesn't do anything, but it tests non-NULL. This way, extensions (or VFSes) that use sqlite3_mutex_alloc() can tell the difference between an OOM error and mutexes being disabled. check-in: 451fd175 user: drh tags: trunk
2010-05-04
18:50
When sqlite3PagerPagecount() is called without any locks, always return the physical file size, not the logical file size. check-in: 4016b422 user: drh tags: trunk
17:38
Be sure to release all wal-index locks before closing the wal-index. check-in: b15b67fa user: drh tags: trunk
17:20
Relax an over-zealous assert() in sqlite3WalUndo(). check-in: 8f9d22d5 user: drh tags: trunk
16:33
Take care not to invoke the xShmClose method of the VFS with a NULL shared memory object. check-in: 1465d384 user: drh tags: trunk
15:20
Add a test case to verify that log files containing pages that are not a power-of-two bytes in size are handled correctly. check-in: c2bf693f user: dan tags: trunk
14:47
Fix problems with recovering wal files that use a page-size other than the default. check-in: 1a391f3c user: dan tags: trunk
11:06
Fix a typo in walfault.test. check-in: 232dbe8e user: dan tags: trunk
10:36
Test that the correct number of padding frames are appended to the log file after committing a transaction in synchronous=FULL mode. check-in: a60104aa user: dan tags: trunk
2010-05-03
19:20
Unset some global TCL variables prior to use in test where prior tests can have those same variables set to an array value. check-in: 49bef00e user: drh tags: trunk
19:17
Fix a bug in the computation of the current time for the alternative CURRENT_TIMESTAMP functions used when SQLITE_OMIT_DATETIME is defined. check-in: e7ded46b user: drh tags: trunk
18:51
Documentation stubs for sqlite3_wal_autocheckpoint and sqlite3_wal_checkpoint. check-in: 31376242 user: drh tags: trunk
18:22
Fix a bug in the xCurrentTime() method of the os_unix.c VFS. check-in: 551df11a user: drh tags: trunk
18:01
Add a test to simulate an OOM during log recovery to walfault.test. check-in: 7ed85e87 user: dan tags: trunk
17:24
Clear global variable "seconds" before use in walthread.test. check-in: a35551a5 user: drh tags: trunk
17:18
Fix a couple of errors in WAL code that can occur in an OOM situation. check-in: 9d3f3736 user: dan tags: trunk
16:36
Update the crash-test VFS in test6.c to pass-through the shared-memory methods to the real underlying VFS. This fixes the walcrash.test script. check-in: ea09ff37 user: drh tags: trunk
16:30
Change the VFS definition so that all methods take a VFS object pointer as their first parameter. check-in: 43b5b07f user: drh tags: trunk
15:58
Have sqlite3_wal_checkpoint() handle a zero-length string in the same way as a NULL pointer. Fix "PRAGMA wal_checkpoint" so that it checkpoints all attached databases. check-in: 7fecd21f user: dan tags: trunk
