| 18:12 | Fix RTREE so that it does not run queries against the sqlite_stat1 if that table does not exist. (check-in: 48526a2fe5 user: drh tags: tree-stat1-fix) | |
| 18:06 | Remove an extra "finish_test" from the end of rtreeC.test. (check-in: bfbb6dd84b user: drh tags: tree-stat1-fix) | |
| 16:16 | Improve the error messages generated by the rtree module when a constraint fails. (check-in: 3ad2531efb user: dan tags: trunk) | |
| 16:15 | Lemon enhancement: avoid unnecessary reduce actions that convert one non-terminal into another but have no side effects. (check-in: a86e782ad1 user: drh tags: trunk) | |
| 14:24 | Fix comment typos and improve clarity of presention in Lemon. The output should be identical. (check-in: b91a5b8297 user: drh tags: trunk) | |
| 02:57 | Merge changes from trunk. (check-in: 815cc2bb48 user: drh tags: apple-osx) | |
| 00:10 | Update the configure script with additional hints on the location of tclConfig.sh, hints needed by the latest versions of Xcode. (check-in: 90411a2816 user: drh tags: trunk) | |

| 23:25 | More tweaks to improve the performance of the insert logic, slightly. (check-in: dec1307581 user: drh tags: trunk) | |
| 20:03 | Simplify the sqlite3BtreeInsert() interface by gathering the five arguments describing the content to be inserted into the new BtreePayload structure, and thus reducing the number of parameters from eight to four. (check-in: 55f348cdd2 user: drh tags: trunk) | |
| 19:10 | Remove some unused legacy code from the btree insert logic. (check-in: 2ce1166717 user: drh tags: trunk) | |
| 18:50 | Use pthreads mutexes and conditions to synchronize threads in bc_test1. (check-in: f33aa76f07 user: dan tags: begin-concurrent) | |
| 12:29 | Yet another minor size reduction and performance increase in the b-tree insert logic. (check-in: 1dbaf7a119 user: drh tags: trunk) | |
| 11:23 | Small size reduction and performance increase in the sqlite3BtreeInsert() logic. (check-in: 656aa1ecf5 user: drh tags: trunk) | |
| 00:45 | Add the shell-script used for routine performance testing. (check-in: 8e366f18f5 user: drh tags: trunk) | |

| 23:51 | Add a simple TCL script for summing cachegrind information for each VDBE opcode. (check-in: 96cf821b6a user: drh tags: trunk) | |
| 21:40 | Another optimization on the OP_Column opcode. (check-in: 1765672c25 user: drh tags: trunk) | |
| 20:58 | Fix typo in comment. (check-in: 9db8f21473 user: mistachkin tags: trunk) | |
| 19:51 | Slight performance improvement in the OP_Column opcode. (check-in: 5c15747439 user: drh tags: trunk) | |
| 18:09 | Remove the sqlite3PagerClearCache() routine, which does not accomplish anything useful. (check-in: f250166bb3 user: drh tags: trunk) | |
| 15:53 | Performance optimization and size reduction on the freeP4() routine. (check-in: 4dc56e8684 user: drh tags: trunk) | |
| 15:24 | Increase the version number to 3.14.0 since we are already making significant code changes. (check-in: 1a0d05765f user: drh tags: trunk) | |
| 15:15 | Use sqlite3VdbeAddOp0() to code OP_Expire, to save a few bytes. (check-in: 3d55d24dcb user: drh tags: trunk) | |
| 14:54 | Optimizations to link list merge sort code in vdbesort.c, pcache.c, and rowset.c. Resulting binaries are 10 bytes smaller and use 0.03% fewer CPU cycles. (check-in: 9033afbb31 user: drh tags: trunk) | |
| 14:11 | For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. (check-in: 559733b09e user: drh tags: trunk) | |
| 13:44 | Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc93 user: drh tags: orderby-limit) | |
| 12:22 | Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. (check-in: 645bd696df user: drh tags: trunk) | |
| 00:21 | A few simple test cases for the ORDER BY LIMIT optimization. (check-in: 08849eab0f user: drh tags: orderby-limit) | |

| 22:40 | Appears to work now. Needs test cases, more comments, and code optimization. (check-in: 990fe50c91 user: drh tags: orderby-limit) | |
| 22:13 | In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. (check-in: 852d1eda6e user: drh tags: orderby-limit) | |
| 19:31 | Fixup comments on wctrlFlags value definitions. (check-in: 58b516e8c0 user: drh tags: trunk) | |
| 18:56 | Clean up the WHERE_* macros used for the wctrlFlags parameter on the sqlite3WhereBegin() interface, freeing up some bits to be used for other things. (check-in: d01305841d user: drh tags: trunk) | |
| 17:51 | Optimization marks in vdbe.c. No logic changes. (check-in: cf2737415a user: drh tags: trunk) | |
| 16:58 | Performance improvement in the OP_Column opcode. (check-in: 4737cadc41 user: drh tags: trunk) | |
| 16:21 | Add test cases to test some fts3/4 edge case behaviour surrounding the '*' character. (check-in: 1f577e1f08 user: dan tags: trunk) | |
| 11:12 | Small size reduction and performance improvement in the OP_Column opcode. (check-in: 0d7730611b user: drh tags: trunk) | |

| 21:03 | Add the "scrub" utility program that simultaneously backs-up a live database and erases all deleted content. (check-in: c981ab2a47 user: drh tags: trunk) | |
| 21:01 | Omit the unnecessary WHERE_REOPEN_IDX flag in the WHERE interface. (check-in: 915416d15f user: drh tags: trunk) | |
| 20:53 | Merge the 3.13.0 release changes. (check-in: e2e9b98556 user: drh tags: apple-osx) | |
| 10:57 | Version 3.13.0 (check-in: fc49f556e4 user: drh tags: trunk, release, version-3.13.0) | |
|
2016-05-17

| 21:17 | Enhance the scrub utility program so that it does a FULL checkpoint prior to starting the backup, to ensure that the database file content matches what needs to be backed up without having to look at the WAL file. (Closed-Leaf check-in: ab1c5ce50f user: drh tags: scrub-backup) | |
| 17:11 | Merge the latest changes from trunk. (check-in: 5021dfe1f3 user: drh tags: scrub-backup) | |

| 13:37 | Merge recent fixes from trunk. (check-in: 0d9b82afea user: drh tags: apple-osx) | |
| 11:55 | Disable shell.exe test cases for UTF8 filenames as they do not work on MinGW. (check-in: 386bcbba8e user: drh tags: trunk) | |
|
2016-05-13
| ||
| 17:22 | Improvements to a comment in the pcache.c file. No changes to code. (check-in: b369980f0c user: drh tags: trunk) | |
| 15:22 | Remove the unused PGHDR_NEED_READ flag. Add invariant checking (during SQLITE_DEBUG builds only) for the PgHdr object. (check-in: 771c5411e9 user: drh tags: trunk) | |
| 12:12 | Clarification of the pagerFlushOnCommit() logic. (check-in: 3401d9dcdb user: drh tags: trunk) | |
| 11:50 | Fix pager_end_transaction() to ensure that a ROLLBACK does not clobber unwritten pages in a TEMP file pcache. (check-in: 9495d33879 user: drh tags: trunk) | |
| 04:24 | Additional debugging and tracing logic for pcache.c, turned off by default using an "#if 0". (check-in: 32a62e3bd4 user: drh tags: trunk) | |
