This is equivalent to a diff from 28d0d771 to 82dd61fc
2010-03-22
| ||
23:55 | Sync the database file after a rollback. This is a cherrypick merge of check-in [b21b911f23]. (Leaf check-in: 82dd61fc user: drh tags: branch-3.6.22) | |
2010-03-03
| ||
22:40 | Modify the sqlite3_log() interface and implementation so that it never uses dynamic memory allocation - to avoid deadlocking when called while holding the memory allocator mutex. Cherry-pick merge of [28d1bc98d6]. (check-in: 6f368b54 user: drh tags: branch-3.6.22) | |
2010-02-25
| ||
01:47 | Start a new branch for release 3.6.22 plus limited enhancements and fixes. This first check-in includes the performance enhancements of check-ins [26cb1df735], [61a2c8d4d6], and [27dc5b1c52] (check-in: 95882598 user: drh tags: branch-3.6.22) | |
2010-01-06
| ||
13:07 | Fix an issue with lemon generating incorrect grammars. This issue does not effect SQLite. (check-in: 077a6bee user: drh tags: trunk) | |
00:00 | Version 3.6.22 (check-in: 28d0d771 user: drh tags: trunk, release) | |
2010-01-05
