| 16:42 | Simplification and performance tweaks in vdbeSorterMerge(). (Closed-Leaf check-in: 99e34bdce4 user: drh tags: merge-sort) | |
| 14:36 | Reduce the number of VdbeRecordUnpack() calls made in vdbesort.c. (check-in: 666c2c3cff user: dan tags: merge-sort) | |
| 00:17 | The build works again with -DSQLITE_OMIT_MERGE_SORT. The merge-sorter now avoids spilling to disk (letting the in-memory linked list grow without bound) if PRAGMA temp_store=3. (check-in: 68e26c4487 user: drh tags: merge-sort) | |
|

| 21:42 | Remove some dead code. Fix a faulty assert(). Improve some variable names. (check-in: a9a64592cf user: drh tags: merge-sort) | |
| 18:03 | Combine two malloc calls in vdbesort.c. (check-in: cf48ad8353 user: dan tags: merge-sort) | |
| 15:41 | Reduce the number of malloc() calls made when creating an index on more than 2 columns. (check-in: 065b0c9858 user: dan tags: merge-sort) | |
| 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) | |
|

| ||
| 16:01 | Use OP_SorterOpen instead of OP_OpenEphemeral to implement GROUP BY. (check-in: ebf819aaa5 user: drh tags: merge-sort) | |
| 15:32 | Experimental code-generator changes to utilize new opcodes for sorting. (check-in: bab2e560f6 user: drh 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) | |
|
2011-08-30
| ||

| 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) | |
|
2011-08-29
| ||
| 18:24 | Fix a broken assert() statement in select.c. (check-in: ad78ef2b3a user: dan tags: trunk) | |
| 11:56 | Back out [05c9832e5f6eb] since it was causing a performance regression with no obvious benefit. (check-in: 639cc85a91 user: drh tags: trunk) | |
| 03:08 | Merge performance enhancements into trunk. (check-in: 5a00d24b27 user: drh tags: trunk) | |
| 02:49 | About a 1% overall performance improvement by using a macro to avoid no-op calls to sqlite3MemReleaseExternal(). (Closed-Leaf check-in: ff71d20a9e user: drh tags: experimental) | |
| 02:16 | Small performance improvement to OP_Column. (check-in: b6b73a747a user: drh tags: experimental) | |
|
2011-08-28
| ||
| 02:15 | About a 3% improvement in the performance of OP_Column. (check-in: edff9d4a99 user: drh tags: experimental) | |
| 00:19 | Correctly display P4_ADVANCE values on opcode traces. Mark an always-taken branch in OP_Column as such. (check-in: 087dc96086 user: drh tags: experimental) | |
|
2011-08-27
| ||
| 18:48 | Experimental changes to improve the performance of OP_Next. (check-in: 1a24984525 user: dan tags: experimental) | |

| 19:20 | Merge the latest trunk changes into the sessions branch. (check-in: eb036d6f81 user: drh tags: sessions) | |
| 19:18 | Merge the latest trunk changes into the apple-osx branch. (check-in: 55af80035f user: drh tags: apple-osx) | |
| 18:28 | Veryquick and min.rc tests now passing. (Closed-Leaf check-in: a7e1846882 user: drh tags: stat3-3.7.2) | |
| 18:04 | Merge the branch-3.7.2 changes into the stat3-3.7.2 subbranch. Also fix some test script issues. (check-in: a42db19d52 user: drh tags: stat3-3.7.2) | |
| 17:17 | Cherrypick the recursion fix to test_vfs.c from [065e5a5ea4f82]. Also fix the nan.test module to handle upper/lower case changes in TCL. (check-in: 41b5f86971 user: drh tags: branch-3.7.2) | |
| 15:51 | Get stat3 working after import from trunk-based the stat3-enhancement branch. There is still a problem in the wal2 test. (check-in: 01cc4ff6af user: drh tags: stat3-3.7.2) | |
| 13:52 | Merge branches branch-3.7.2 and stat3-enhancement into a new branch for testing purposes. (check-in: 0df04f920b user: drh tags: stat3-3.7.2) | |
| 13:16 | Merge the stat3-enhancement branch with trunk, but keep the resulting merge in a separate branch for now. (check-in: 63f2c7859f user: drh tags: stat3-trunk) | |
| 11:25 | Update compiler error message regarding the choice of memory allocator defines. (check-in: 1dada51582 user: mistachkin tags: trunk) | |

| 05:40 | In the MSVC makefile, allow symbols to be enabled without NDEBUG defined. Also, for the win32lock test, make sure the database is closed prior to shutdown. (Closed-Leaf check-in: 5ed7633d41 user: mistachkin tags: winNativeHeap) | |
| 01:45 | Disable checking the winMemData structure signature when compiled with NDEBUG. (check-in: 50edc2f914 user: mistachkin tags: winNativeHeap) | |
| 01:32 | Allow the Win32 native heap flags to be overridden at compile-time. (check-in: 1c2ecec8e7 user: mistachkin tags: winNativeHeap) | |
| 00:34 | Create a new pager type, PAGER_SORTER, for use in the external merge sort. Such pagers are always held in memory but do report when they are under memory pressure by calling pagerStress. (check-in: c71d73201d user: drh tags: trunk) | |
