| 19:50 | Temporarily back out the 0.5% performance improvement from check-in [632071bac5ff32]. Need a more elaborate solution that works with reentrant virtual tables and SQL functions. (check-in: 42736fb0ad user: drh tags: trunk) | |
| 09:48 | Refinements to synchronous logic: (1) Use PAGER_SYNCHRONOUS_FULL rather than the corresponding magic number. (2) Honor SQLITE_NO_SYNC on xDelete calls with sync (3) Count xDelete syncs during testing (4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal unlink are off by default. (check-in: e3157cb5ad user: drh tags: trunk) | |
| 02:34 | Add and use the sqlite3VdbeZeroRegister() interface for coding the common operation of writing zero into a register. (Leaf check-in: 1c8d300189 user: drh tags: zero-register) | |

| 22:14 | In the VDBE loop, only check for OOM errors at jumps rather than after every opcode, for about a 0.5% performance increase. (check-in: 632071bac5 user: drh tags: trunk) | |
| 20:04 | Improve performance of fts5 prefix queries on detail=col tables. (check-in: ca11f46db0 user: dan tags: trunk) | |
