| 18:22 | Merge updates from trunk. (Closed-Leaf check-in: 45acf6a851 user: mistachkin tags: winViewFlush) | |
| 18:20 | Enhancements to OSTRACE usage in the Win32 VFS. (check-in: ab5800291e user: mistachkin tags: trunk) | |
| 02:27 | Fix the ".testctrl imposter" command in the command-line shell to be consistent in error reporting and results with the other .testctrl commands. (check-in: 0ec08ba8a0 user: drh tags: trunk) | |
| 00:21 | Using MSVC, get the sqlite3IoTrace variable working with the USE_STDCALL and/or DYNAMIC_SHELL options. (check-in: fe976c9130 user: mistachkin tags: trunk) | |
| 00:19 | In the MSVC Makefile, make the DYNAMIC_SHELL option work without USE_STDCALL. (check-in: 25b46a9c7e user: mistachkin 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) | |

| 21:12 | • Fixed ticket [38b1ae018f]: Assertion fault on valid FTS4 query plus 5 other changes (artifact: 48cf60d576 user: drh) | |
| 21:11 | • Fixed ticket [6bfb98dfc0]: False report of database corruption on an INSERT plus 5 other changes (artifact: f41e9efab1 user: drh) | |
| 20:41 | Fix harmless compiler warnings coming from MSVC64 in test code. No changes to the core. (check-in: 274d2a2266 user: drh tags: trunk) | |
| 19:53 | Modify various test cases so that they work if the file is extended in units of the system page-size. (check-in: 0e3d511927 user: dan tags: two-mappings) | |
| 19:46 | Increment the version number to 3.7.16.1. (check-in: 7e32eb7b66 user: drh tags: trunk) | |
| 17:20 | • Fixed ticket [a179fe7465]: Incorrect output order on a join with an ORDER BY plus 3 other changes (artifact: 16d5b73121 user: drh) | |
| 17:20 | In order to optimize out the ORDER BY clause, outer loops must generate values for ORDER BY terms that are unique or else the inner loops must generate no more than a single row. Fix for ticket [a179fe7465]. (check-in: 2936f7466e user: drh tags: trunk) | |
| 16:42 | Restore additional ORDER BY optimizations that where broken by the recent ORDER BY fix. (Closed-Leaf check-in: c77ee6e20d user: drh tags: orderby-fix) | |
| 16:05 | Improved optimization of ORDER BY. (check-in: 97e5c70f2f user: drh tags: orderby-fix) | |
| 15:04 | A fix and test-case for the ORDER BY problem identified by ticket [a179fe7465]. This change causes sorting to occur in some cases where it is not strictly necessary. Further work is needed to avoid those extra sorts. (check-in: 488089e615 user: drh tags: orderby-fix) | |
| 14:28 | • Ticket [a179fe7465] Incorrect output order on a join with an ORDER BY status still Open with 3 other changes (artifact: 82a0e96f59 user: drh) | |
| 11:39 | • Ticket [a179fe7465]: 7 changes (artifact: 41623a1ae4 user: drh) | |
| 03:15 | Candidate fix for ticket [6bfb98dfc0c]: Make sure invalid cursors drop all references to database pages prior to doing any insert or update. (check-in: 322a5f086d user: drh tags: trunk) | |
| 02:54 | • New ticket [6bfb98dfc0] False report of database corruption on an INSERT. (artifact: a6e343197b user: drh) | |

| 22:42 | Allow the xAccess method in the VFS to return -1 to signal an I/O error, and in particular an SQLITE_IOERR_NOMEM. (CVS 4925) (check-in: 3cb704c4c4 user: drh tags: trunk) | |
| 17:59 | Allow creation of ephemeral pseudo-tables - pseudo-tables that copy a pointer to a row when inserted instead of copying the row data. (CVS 4924) (check-in: 1a58a87023 user: danielk1977 tags: trunk) | |
| 15:07 | Added the speed4p.test script for testing performance of views and triggers. (CVS 4923) (check-in: adf7645f9a user: drh tags: trunk) | |

| 13:50 | Regression tests now work - except for some changes in error message text. The library is now safe to use for experimental work. (CVS 885) (check-in: 8a593e9c2d user: drh tags: trunk) | |
| 13:01 | Fix a segfault in the trigger code. (CVS 884) (check-in: 7672914b19 user: drh tags: trunk) | |
| 12:51 | Changes to the "sqlite" structure that allow simultaneous operations on multiple database files. Many regession tests pass - but not all of them. Do not use this version except for debugging SQLite itself. (CVS 1731) (check-in: 9ac71c329e user: drh tags: trunk) | |
