| 17:45 | Add another performance test case to speedtest1. This case is another ORDER BY test but this time without LIMIT. check-in: 9ab7ffd5 user: drh tags: trunk | |
| 14:54 | Add an ORDER BY test case to speedtest1.c check-in: 58812264 user: drh tags: trunk | |
| 11:00 | Detect when a VdbeCursor is still pointing at a valid row but that row has moved, and invalidated the return from prior sqlite3BtreeDataFetch() or sqlite3BtreeKeyFetch() calls. check-in: e6798871 user: drh tags: trunk | |
