35 check-ins using file src/os.h version 6f529984

2010-06-11
17:01
Refactor and simplify the logic used to change journalmode. check-in: 95cc3f6f user: drh tags: trunk
2010-06-10
16:25
Adding original art for the new SQLite logo. check-in: af353bd8 user: drh tags: trunk
14:07
Add the SQLITE_TESTCTRL_PGHDRSZ verb for sqlite3_test_control() used to get the size of pcache headers for testing purposes. check-in: 5d694f04 user: drh tags: trunk
10:51
Update the test VFS in test_journal.c so that it implements the xCurrentTimeInt64 method. check-in: ec3b4a7e user: drh tags: trunk
06:53
Store the MemPage structure in memory following, instead of preceding, the page data for cached pages. This reduces the likelihood of a corrupt database page image causing SQLite to read past the end of a buffer. check-in: 0ce42e76 user: dan tags: trunk
01:07
Remove a condition that must always be true. Replace it with an assert(). check-in: 7abcd54e user: drh tags: trunk
2010-06-09
19:01
Fix test script problems causing errors in the "inmemory_journal" permutations. check-in: ea05b7f9 user: dan tags: trunk
16:58
When restarting (wrapping) a log file, set all unused aReadMark[] slots to READMARK_NOT_USED instead of 0. Setting them to 0 does not cause a problem, but may cause SQLite to obtain and release a few more file locks than would otherwise be necessary. check-in: 0797b10c user: dan tags: trunk
15:47
Fix for ticket [f973c7ac31]. check-in: 6eb058dd user: dan tags: trunk
14:45
Shift the meaning of aReadMark[] back so that +1 offset from mxFrame is removed. Add the new READMARK_NOT_USED value (0xffffffff) instead of zero to signal an aReadMark[] that is not in use. check-in: c576827d user: drh tags: trunk
11:28
Simpler fix for the race condition also fixed by [7c102c7b5f] check-in: 3c2de820 user: dan tags: trunk
11:02
Fix for race condition in WAL locking code. Closed-Leaf check-in: 7c102c7b user: dan tags: mistake
2010-06-08
15:50
Close database opened by tester.tcl when it is sourced in all.test. Because test scripts are now run in slave interpreters, this connection was not being closed by the first script run as it was previously. check-in: b072e9f6 user: dan tags: trunk
15:16
Changes to wal3.test to support small default cache size settings. And builds that create autovacuum databases by default. check-in: ac4cc257 user: dan tags: trunk
2010-06-07
19:26
In os_unix.c, call munmap() to unmap a shared-memory region prior to closing the associated file descriptor. check-in: 95cc976f user: dan tags: trunk
17:47
Change all.test, quick.test and permutations.test so that they use a separate interpreter for each test file. check-in: 7c33eb5a user: dan tags: trunk
14:28
Refactor some of the global variables and commands used by tester.tcl. check-in: c2edf8e1 user: dan tags: trunk
06:11
Add a couple of extra coverage tests for wal.c. check-in: cfe60254 user: dan tags: trunk
2010-06-05
19:18
Add further test cases for the logic in sqlite3WalBeginReadTransaction(). check-in: a49713db user: dan tags: trunk
18:34
Clarify the purpose of a test for a race-condition in sqlite3WalBeginReadTransaction(). check-in: c041c6a9 user: dan tags: trunk
18:12
Remove a condition from sqlite3WalRead() that is unreachable as of the changes to clear entries out of the wal-index hash tables on transaction or savepoint rollback. check-in: 39420473 user: dan tags: trunk
14:42
Mark a condition in wal.c as ALWAYS(). check-in: 3fe0cc78 user: dan tags: trunk
11:53
Add extra coverage test cases for wal.c. No changes to production code. check-in: f9d4ae0e user: dan tags: trunk
2010-06-04
18:38
Clarify an assert in sqlite3WalExclusiveMode(). check-in: 25585069 user: dan tags: trunk
17:16
Remove an unnecessary branch from wal.c. check-in: 8e54786c user: dan tags: trunk
15:59
Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". check-in: ca327e32 user: dan tags: trunk
12:22
Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. check-in: 157feba1 user: dan tags: trunk
11:56
If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. check-in: b813233d user: dan tags: trunk
10:37
Fix a problem where an SQLITE_BUSY in the checkpoint code was being treated as an IO error (abandoning, instead of just limiting, the checkpoint). check-in: 02c4040c user: dan tags: trunk
2010-06-03
19:10
Fix another problem in test_vfs.c. check-in: df7d5989 user: dan tags: trunk
18:20
Have test_vfs.c simulate IO errors in xShmLock. check-in: fcbf7cf1 user: dan tags: trunk
18:02
Performance fix for winShmClose(). check-in: ed7774de user: drh tags: trunk
16:58
Add extra tests for removing elements from wal-index hash tables as part of a rollback. check-in: af3e598a user: dan tags: trunk
12:35
Delay opening the sub-journal until SQLite actually needs to write data to it. check-in: c43deb33 user: dan tags: trunk
12:09
Remove global variables when compiled with SQLITE_OMIT_WSD check-in: dd10a547 user: drh tags: trunk
