| 19:27 | Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. check-in: 51039b35 user: drh tags: trunk | |
| 19:26 | Simplifications to the sqlite3ResetInternalSchema() logic to eliminate unreachable branches. check-in: a4c3ac98 user: drh tags: trunk | |
| 18:34 | Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. check-in: a89f24e2 user: drh tags: trunk | |
