| 14:54 | Optimizations to link list merge sort code in vdbesort.c, pcache.c, and rowset.c. Resulting binaries are 10 bytes smaller and use 0.03% fewer CPU cycles. check-in: 9033afbb user: drh tags: trunk | |
| 14:11 | For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. check-in: 559733b0 user: drh tags: trunk | |

| 12:22 | Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. check-in: 645bd696 user: drh tags: trunk | |
