| 15:16 | Reduce the size of the large allocation (approx 8KB for every 4000 frames in the log) that occurs during checkpoint. Use the 'scratch' memory for this allocation instead of the general purpose allocation. check-in: 29887487 user: dan tags: trunk | |
| 14:17 | Fix up a branch in sqlite3ValueFromExpr() so that we can achieve full branch test coverage regardless of whether or not SQLITE_ENABLE_STAT2 is used. check-in: af471ed7 user: drh tags: trunk | |
| 12:52 | Change the name of the shared-memory file on windows from *-wal-index to *-shm, for consistency with unix. check-in: 5995cb15 user: drh tags: trunk | |

|
2010-06-24
| ||
| 19:16 | Add test cases to pager1.test and pagerfault.test. check-in: 4941e437 user: dan tags: trunk | |
| 18:36 | Revert to allowing a cache spill during writes of multiple pages within a single sector as long as the spill does not require a journal sync and a new journal header. check-in: 7d83fbae user: drh tags: trunk | |

|
2010-06-23
| ||
| 22:00 | Fix and/or improve comments in wal.c. No code changes. check-in: ee9991be user: drh tags: trunk | |

| 18:12 | Change the name of IOCAP_SAFE_DELETE to IOCAP_UNDELETABLE_WHEN_OPEN. Have the xDeviceCharacteristics() method of the win32 VFS return this flag. check-in: 5a5ff4e3 user: dan tags: experimental | |
| 17:26 | Add tests to pager1.test and pagerfault.test. check-in: f5df83fd user: dan tags: experimental | |
| 15:10 | Change the unix VFS to always allocate shared-memory using a file in the same directory as the database. Otherwise, a chroot might cause different processes to use different shared memory files resulting in database corruption. check-in: 2241788b user: drh tags: trunk | |
| 11:30 | Add tests to pager1.test and pagerfault.test. check-in: 58c0b5bf user: dan tags: experimental | |

| 17:05 | Apply [b9b11855e8] (the alternate fix to [fc62af4523]) to the trunk. check-in: 9a949a3a user: dan tags: trunk | |
| 16:44 | Merge trunk change [7c3a86b9c7]. check-in: bd7bc4e0 user: dan tags: experimental | |
| 16:44 | A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. check-in: b9b11855 user: dan tags: experimental | |
| 16:08 | Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. check-in: 7c3a86b9 user: drh tags: trunk | |

| 02:13 | Bug fix: Only trust the database size number at offset 28 if the change counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version. check-in: f80c3f92 user: drh tags: trunk | |

| 16:16 | Add the new xShmMap (formerly xShmPage) to os_win.c. check-in: 13e7a824 user: dan tags: experimental | |
| 14:07 | Remove xShmGet/Size/Release from the sqlite3_vfs structure. Change the name of xShmPage to xShmMap. Remove some code that is now unused from os_unix.c and some of the test VFS implementations. check-in: fc0cabc1 user: dan tags: experimental | |

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 | |

| 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 | |
