| 09:59 | Modify an assert() within sqlite3PagerWalFramesize(), a function only ever used by zipvfs, to account for recent zipvfs changes. (check-in: 3bd7c1b2 user: dan tags: trunk) | |
| 02:20 | Fix harmless warnings on 32-bit MSVC builds. (check-in: 5192f964 user: drh tags: trunk) | |
| 01:50 | Make sure of the strchrnul() library function on platforms where it is available. (check-in: ef1aa10b user: drh tags: trunk) | |
| 01:29 | Merge micro-optimizations into trunk after fixing the build on MSVC. Performance now shows 7.58% faster than the 3.8.6 release on x64 with gcc 4.8.1 and -Os. (check-in: 1de558bc user: drh tags: trunk) | |
| 01:21 | Fix compiler warnings and change the nullMem structure initializer into a format that MSVC can understand. (Closed-Leaf check-in: 163bfae8 user: drh tags: micro-optimizations) | |

| 23:37 | Performance improvement and slight size reduction to the comparison operators in the VDBE. (check-in: 14052a7d user: drh tags: micro-optimizations) | |
| 16:41 | In the Mem object, stop requiring that Mem.xDel be NULL when the MEM_Dyn bit is clear. Also reduce the amount of initialization of Mem objects. All for a small size reduction and performance increase. (check-in: fdddb477 user: drh tags: micro-optimizations) | |
| 14:52 | Improved interface to the Mem object handling. Small size reduction and performance increase. (check-in: 4e437844 user: drh tags: micro-optimizations) | |
|

| ||
| 21:54 | Continuing cleanup of memory register memory allocation handling. (check-in: 2598aedc user: drh tags: micro-optimizations) | |
| 20:05 | Make sure registers are cleared properly prior to being used to store the result of an OP_Column operator. (check-in: 78fb8838 user: drh tags: micro-optimizations) | |
| 18:22 | Simplification of the OP_Column logic for the case of rows with overflow. (check-in: f7367803 user: drh tags: micro-optimizations) | |
| 14:55 | Remove an unused parameter from sqlite3VdbeIdxRowid(). This is cosmetic only as the C-compiler optimizers were already omitting this parameter on amalgamation builds. (check-in: a10a6bba user: drh tags: micro-optimizations) | |
| 14:37 | Reduce the number of arguments to RecordCompare functions from 4 to 3, resulting in a small performance increase. (check-in: 8239c35a user: drh tags: micro-optimizations) | |
| 14:16 | Reorder the elements of the Mem object for a small size reduction and performance improvement. Moved into a branch because MSVC is unable to handle named structure initializer on nullMem. (check-in: 0be3019e user: drh tags: micro-optimizations) | |
| 13:30 | Changes to sqlite3VdbeRecordUnpack() to make it slightly smaller and faster. (check-in: 8fb90da7 user: drh tags: trunk) | |
| 03:24 | Performance improvement to the sqlite3MemCompare() routine by factoring out sqlite3BlobCompare(). (check-in: 20ed2321 user: drh tags: trunk) | |
|
2014-09-15
| ||
| 16:53 | Fix tool/showwal.c so that it handles WAL files that contain 64KiB pages. (check-in: 4060efb6 user: dan tags: trunk) | |
| 16:50 | Avoid attempting to call the xFetch() method of an sqlite3_io_methods object with a version number less than 3. (check-in: dedaa6fb user: dan tags: trunk) | |
| 14:59 | Remove the EXPENSIVE_ASSERTS in pcache.c having to do with the pSynced field of the Pcache object, as they are incorrect, as revealed by recent pcache enhancements. (check-in: 69a64560 user: drh tags: trunk) | |
| 14:46 | Do not flatten aggregate subqueries that contain min() or max() functions so that if the min()/max() are discarded by the outer query, they still function and cause non-aggregate expression to be evaluated on the minimal or maximal row. (check-in: 0bdf1a08 user: drh tags: trunk) | |
