| 18:09 | Remove the sqlite3PagerClearCache() routine, which does not accomplish anything useful. (check-in: f250166bb3 user: drh tags: trunk) | |
| 15:53 | Performance optimization and size reduction on the freeP4() routine. (check-in: 4dc56e8684 user: drh tags: trunk) | |
| 15:24 | Increase the version number to 3.14.0 since we are already making significant code changes. (check-in: 1a0d05765f user: drh tags: trunk) | |
| 15:15 | Use sqlite3VdbeAddOp0() to code OP_Expire, to save a few bytes. (check-in: 3d55d24dcb user: drh tags: trunk) | |
| 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: 9033afbb31 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: 559733b09e user: drh tags: trunk) | |
| 13:44 | Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc93 user: drh tags: orderby-limit) | |
| 12:22 | Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. (check-in: 645bd696df user: drh tags: trunk) | |
| 00:21 | A few simple test cases for the ORDER BY LIMIT optimization. (check-in: 08849eab0f user: drh tags: orderby-limit) | |

| 22:40 | Appears to work now. Needs test cases, more comments, and code optimization. (check-in: 990fe50c91 user: drh tags: orderby-limit) | |
| 22:13 | In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. (check-in: 852d1eda6e user: drh tags: orderby-limit) | |
| 19:31 | Fixup comments on wctrlFlags value definitions. (check-in: 58b516e8c0 user: drh tags: trunk) | |
| 18:56 | Clean up the WHERE_* macros used for the wctrlFlags parameter on the sqlite3WhereBegin() interface, freeing up some bits to be used for other things. (check-in: d01305841d user: drh tags: trunk) | |
| 17:51 | Optimization marks in vdbe.c. No logic changes. (check-in: cf2737415a user: drh tags: trunk) | |
