| 17:07 | Performance improvements to the external merge-sorter. Keep content on an in-memory linked lists rather than an ephemeral table prior to spilling to disk. Use the external merge-sorter to implement ORDER BY and GROUP BY in addition to CREATE INDEX. (check-in: 4c43e8b2d2 user: drh tags: trunk) | |

| 15:08 | Remove unused local variable. (check-in: 61bda876af user: mistachkin tags: trunk) | |
| 11:45 | If all data being sorted fits in memory, avoid writing any data out to temporary files in vdbesort.c. (check-in: 71075673c6 user: dan tags: merge-sort) | |
| 10:31 | Instead of a temporary b-tree, use a linked-list and merge-sort to sort records in main memory in vdbesort.c. (check-in: 7769fb988d user: dan tags: merge-sort) | |
|

| 23:57 | Avoid using uninitialized variables after failures in the merge sort code. (check-in: 2869ed2829 user: drh tags: trunk) | |
| 21:01 | Formerly, we enabled fdatasync() on linux only. But now we learn that fdatasync() is not supported on Android. So we disable fdatasync() on Linux too. It can be reenabled at compile-time for those who really need it. (check-in: 70b5b30956 user: drh tags: trunk) | |
| 20:47 | Add the SQLITE_MAX_SCHEMA_RETRY compile-time option to the set of options understood by "PRAGMA compile_options;" and by the "sqlite_compileoption_used()" function. (check-in: 1b124af40a user: drh tags: trunk) | |
| 19:40 | The server1.test script should only run if mutexes are functional. Fix to the #ifdef change of check-in [9e6a4c1473]. (check-in: 6489848590 user: drh tags: trunk) | |
| 18:35 | Always include the unixShm.id field, even when not debugging. (check-in: 0780347620 user: drh tags: trunk) | |
| 18:04 | Only create the sqlite3OSTrace global variable if compiling with SQLITE_TEST. (check-in: 9e6a4c1473 user: drh tags: trunk) | |
| 17:46 | Backslash escaping is not working right in tostr.awk on the latest ubuntu. The easiest fix is to simply not use any backslashes in the spaceanal.tcl script. (check-in: df55006665 user: drh tags: trunk) | |
| 13:27 | Add checks to make sure cells in corrupt database files do not overflow a page when doing autovacuum. Problem detected by valgrind. (check-in: d0b347b412 user: drh tags: trunk) | |

| 01:29 | Change the build process so that it does not require the unix "sort" command. This avoids confusion between ms-sort and mingw-sort on windows systems. (check-in: f1bd5bbae5 user: drh tags: trunk) | |
| 01:23 | Make sure SQLITE_FCNTL_SIZE_HINT a no-op if the chunk size is not greater than zero. (check-in: 88b763e8d7 user: mistachkin tags: trunk) | |
| 00:58 | Fix a total unimportant file descriptor leak in lemon. This is to silence warning messages. (check-in: e95cf2c576 user: drh tags: trunk) | |
| 00:53 | Fix a buffer overrun in test logic. No impact on the core SQLite. (check-in: 49cd60e38b user: drh tags: trunk) | |
