| 12:56 | Fix a harmless compiler warning. (check-in: a4e47150f3 user: drh tags: trunk) | |
| 03:12 | Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. (check-in: 7fa85eaaaf user: drh tags: trunk) | |

| 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: 81987c8ceb 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: 9b4d7226bc 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: f4ac1bf28c 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: b4bd2a062c user: drh tags: trunk) | |
| 00:09 | Merge the latest trunk changes and the fix for the crash on a corrupt database. (check-in: 0b35346c32 user: drh tags: orderby-planning) | |

| 19:45 | Merge from trunk the fix for the crash on a corrupt database. (check-in: 8cb2b02baa user: drh tags: threads) | |
| 19:43 | Merge in fixes (including the corrupt-database crash fix) and performance enhancements from trunk. (check-in: fc8ca1a87e user: drh tags: sessions) | |
| 15:14 | Add an extra test case for the potential buffer overread patched by [28ddecff04]. (check-in: f585f5d7a0 user: dan tags: trunk) | |
| 15:05 | Add a test case to verify that the previous change avoids excess buffer overread in sqlite3VdbeRecordCompare(). (check-in: 2b28e8d582 user: drh tags: trunk) | |
| 14:51 | Earlier detection of corruption in sqlite3VdbeRecordCompare() in order to avoid a potential buffer overread. (check-in: 28ddecff04 user: drh tags: trunk) | |
| 12:02 | Add an assert() and a comment to clarify the operation of the vdbeRecordCompareInt() routine. (check-in: 851abdb8fd 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: 7922809ee0 user: drh tags: trunk) | |
| 18:29 | Merge enhancements and fixes from trunk. (check-in: e005f2d6dd 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: 9ab7ffd592 user: drh tags: trunk) | |
| 14:54 | Add an ORDER BY test case to speedtest1.c (check-in: 588122641e user: drh tags: trunk) | |
| 14:12 | Enable four sorting threads by default in the command-line shell. (check-in: 1cab83577c user: drh tags: threads) | |
| 13:17 | Merge all fixes and enhancements from trunk. (check-in: b415dfb6cb user: drh tags: threads) | |
| 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: e6798871ce user: drh tags: trunk) | |

| 16:30 | Remove unused variables Parse.nColCache and Parse.iColCache. (check-in: 4d7551ce46 user: dan tags: trunk) | |
| 15:00 | Fix arithmetic operators so that they do not change the affinity of their input operands. Ticket [a8a0d2996a]. (check-in: 221f8f9447 user: drh tags: trunk) | |
| 12:33 | Cancel column-cache entries that are involved in a comparison operator since the comparison might have forced an affinity change. Originally proposed as a fix for ticket [a8a0d2996a], but later determined to be incorrect. (Closed-Leaf check-in: 0b95b7a874 user: drh tags: tkt-a8a0d2996a) | |
| 11:23 | Avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. (check-in: db7d62c8d5 user: dan tags: trunk) | |

| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. (Closed-Leaf check-in: e3d2be3ba4 user: dan tags: shm-mapping-fix) | |
