29 check-ins using file src/vdbeapi.c version f2da22e5

2010-05-05
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)
14:32
Use VFS method xCurrentTimeInt64 instead of xCurrentTime when it is available. Provide an implementation of xCurrentTimeInt64 for os_unix.c. (check-in: ab77b3ae user: drh tags: trunk)
