| 19:25 | Instead of allocating a single large buffer at the beginning of each sort operation, start with a small buffer and extend it using realloc() as required. (check-in: 81987c8c user: dan tags: orderby-planning) | |
| 18:36 | Minor cleanup of the code in the query planner that computes the costs estimates for the various plans. There are no changes to the costs at this time. But the code is slightly more readable now and that might facilitate future enhancements. (check-in: 9b4d7226 user: drh tags: trunk) | |
| 17:23 | Use xFetch() to access temporary files in vdbesort.c. Use a single large allocation instead of many small allocations when accumulating records in vdbesort.c. This is an interim commit - it allocates a buffer the size of the page-cache every time data is sorted. (check-in: f4ac1bf2 user: dan tags: orderby-planning) | |
| 14:05 | Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a06 user: drh tags: trunk) | |
| 00:09 | Merge the latest trunk changes and the fix for the crash on a corrupt database. (check-in: 0b35346c user: drh tags: orderby-planning) | |

| 15:14 | Add an extra test case for the potential buffer overread patched by [28ddecff04]. (check-in: f585f5d7 user: dan tags: trunk) | |
| 15:05 | Add a test case to verify that the previous change avoids excess buffer overread in sqlite3VdbeRecordCompare(). (check-in: 2b28e8d5 user: drh tags: trunk) | |
| 14:51 | Earlier detection of corruption in sqlite3VdbeRecordCompare() in order to avoid a potential buffer overread. (check-in: 28ddecff user: drh tags: trunk) | |
| 12:02 | Add an assert() and a comment to clarify the operation of the vdbeRecordCompareInt() routine. (check-in: 851abdb8 user: drh tags: trunk) | |

| 20:28 | Adjust the repeat counts on several tests in speedtest1 so that the relative time spent on the test is roughly the same regardless of --size. (check-in: 7922809e user: drh tags: trunk) | |
| 18:29 | Merge enhancements and fixes from trunk. (check-in: e005f2d6 user: drh tags: orderby-planning) | |
| 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) | |

| 16:30 | Remove unused variables Parse.nColCache and Parse.iColCache. (check-in: 4d7551ce user: dan tags: trunk) | |
