| 15:01 | Store values loaded from the stat1 table as logarithmic values in memory. (check-in: 1bd74c49dd user: dan tags: experimental-costs) | |
| 14:42 | Make sure ORDER BY clauses on joins that involve virtual tables and that have a DISTINCT clause work correctly. This is a candidate fix for ticket [388d01d4bb8f9]. Test cases for that ticket will be checked in separately. (check-in: 1711381226 user: drh tags: trunk) | |
| 12:35 | When VDBE_PROFILE is enabled, ignore negative opcode times, which sometimes occur, perhaps due to context swaps. (check-in: 4e88042f9d user: drh tags: trunk) | |

| 20:04 | Changes to the way the planner calculates the costs of various table and index scans. Some test cases still failing. (check-in: c5a6ec0a88 user: dan tags: experimental-costs) | |
| 16:25 | Improved header comment on the vdbesort.c module. No changes to code. (check-in: bf09ce24d0 user: drh tags: orderby-planning) | |
| 15:06 | Reopen the orderby-planning branch and merge in the latest trunk enhancements and fixes. (check-in: 6077ddcd93 user: drh tags: orderby-planning) | |

| 01:37 | Further improvements to the RTREE_DECODE_COORD() method, to take advantage of known processor byte orders when available. This makes the code 3% faster, according to valgrind.

| 17:15 | TCL tests now all pass. (Closed-Leaf check-in: f864baccd3 user: drh tags: rtree-queue) | |
| 16:43 | Rework the way trees of MergeEngine objects are built in vdbesort.c to make it easier to follow. Fix memory leaks that could follow an OOM or IO error. Add various comments to explain functions in vdbesort.c. (check-in: 69026ec7dc user: dan tags: threads) | |

| 21:06 | Initial attempt at getting R-Tree queries to work using a priority queue. This check-in compiles, but R-Trees do not work well. And there are debugging printf()s left in the code. This is an incremental check-in. (check-in: 53688a25c2 user: drh tags: rtree-queue) | |

| 19:23 | Allow the sorter to begin returning data to the VDBE as soon as it is available, instead of waiting until all keys have been sorted. (check-in: cb0ab20c48 user: dan tags: threads) | |
| 18:41 | Improve performance in single-threaded mode by having the final merge pass keys directly to the VDBE, instead of going via a final PMA. (Closed-Leaf check-in: 02610cd9b7 user: dan tags: threads-experimental) | |
| 14:43 | Fix comments on the rtreenode() and rtreedepth() test function in the R-Tree module. (check-in: ade5b986e8 user: drh tags: rtree-enhancements) | |
