| 22:02 | Slight change to the --timer output on wordcount for better display on windows: Avoid showing the full pathname of the executable. (check-in: b9e047b9 user: drh tags: trunk) | |
| 21:59 | Changes some offset and amount parameters from "int" to "u32" to avoid harmless signed/unsigned comparison warnings. (check-in: 4e8c5d07 user: drh tags: trunk) | |
| 21:40 | Modify wordcount so that timer information appears on standard error instead of standard output. Rename the run-wordcount.bash script to run-wordcount.sh and simplify it so that it stands a better chance of running on non-GNU systems. (check-in: 586c11ed user: drh tags: trunk) | |
| 21:23 | Do not reuse factored constants that might have had their encodings changed. (check-in: 487f2036 user: drh tags: trunk) | |
| 20:48 | Fix the code generator to honor turning off constant expression factoring. (check-in: 88262266 user: drh tags: trunk) | |
| 19:27 | Add the --timer option to the wordcount test program. (check-in: a89fdf87 user: drh tags: trunk) | |
| 19:05 | Remove a test from sqlite3VdbeMemFromBtree() which was unnecessary, and after the recent OP_Column refactoring, unreachable. (check-in: 23667f3b user: drh tags: trunk) | |
| 17:24 | Make sure the OP_Next and OP_NextIfOpen opcodes are numbered close together for efficiency in switch() statements. OP_Prev and OP_PrevIfOpen too. (check-in: d4ccf0f5 user: drh tags: trunk) | |
| 16:08 | When one or more arguments to a function are constants, try to factor out just those arguments into initialization code. (check-in: 50d350ab user: drh tags: trunk) | |
| 14:44 | Remove the obsolete TK_CONST_FUNC token type. (check-in: 9b4217f0 user: drh tags: trunk) | |
| 14:33 | Add the ability to factor constant functions out of inner loops. But do not factor out non-constant functions, like random(). (check-in: 1b0f779e user: drh tags: trunk) | |
| 04:18 | Another improvement to OP_Function and an improvement to OP_Move. (check-in: 70b056fb user: drh tags: trunk) | |
| 03:43 | A simple change to the OP_Function opcode improves overall performance by about 0.5%. (check-in: b890eefd user: drh tags: trunk) | |
| 03:12 | Performance optimization to the OP_Next and OP_Prev opcodes. (check-in: ecaac28a user: drh tags: trunk) | |
| 01:33 | Refactor the OP_Column opcode to make it clearer and easier to maintain. Overall, performance tests show about a 1% speed increase with this change. (check-in: 972881c6 user: drh tags: trunk) | |
| 01:04 | Reduce the size of VdbeCursor again, this time without a performance hit. (Closed-Leaf check-in: 93393993 user: drh tags: OP_Column-refactor) | |
| 00:10 | Unpack some fields, adding some space back to the VdbeCursor object, in order to help the code to run a little faster. (check-in: f8d5efcd user: drh tags: OP_Column-refactor) | |

| 21:51 | Reduce the size of the VdbeCursor object from 144 to 120 bytes. (check-in: 5f9d5068 user: drh tags: OP_Column-refactor) | |
| 20:58 | Improved comments on the OP_Column changes. Optimize out loading of overflow pages for content with zero length. Add test cases for the latter. (check-in: 0e05679d user: drh tags: OP_Column-refactor) | |
| 19:28 | Further performance tweaks to OP_Column. (check-in: 0e3f5df6 user: drh tags: OP_Column-refactor) | |
| 17:25 | Refactoring the OP_Column opcode for improved performance and maintainability. (check-in: 7c914e39 user: drh tags: OP_Column-refactor) | |
| 02:53 | Simplifications to the VdbeCursor object. (check-in: 5562cd34 user: drh tags: trunk) | |
| 00:59 | Performance improvement for the OP_MustBeInt opcode in the VDBE. (check-in: 96a65388 user: drh tags: trunk) | |
|

| 18:17 | Fix a harmless MSVC compiler warning. (check-in: 6cc023bb user: drh tags: trunk) | |
| 13:55 | Minor performance improvement to sqlite3SerialTypeGet(). (check-in: 17e8524f user: drh tags: trunk) | |
| 12:33 | Change Noop-comments in where.c into Module-comments, so that they are omitting without SQLITE_ENABLE_MODULE_COMMENTS. (check-in: 3e577f40 user: drh tags: trunk) | |
| 02:34 | Avoid seeking on the main data table during the first loop of an UPDATE if an index is sufficient to check the WHERE clause. (check-in: 57158d9d user: drh tags: trunk) | |
| 00:31 | Fix an requirement mark in a test script so that it matches the typo-corrected requirement. No changes to code. (check-in: 072412d5 user: drh tags: trunk) | |
|

| ||
| 19:32 | Add comments identifing where the skip-scan option is decided in the query planner, to aid in tuning that decision. No changes to code. (check-in: e9df04ce user: drh tags: trunk) | |
| 18:48 | Fix documentation typos. No changes to code. (check-in: 7caeb09c user: drh tags: trunk) | |
| 11:20 | Fix harmless compiler warnings from clang scan-build. (check-in: 8d002740 user: drh tags: trunk) | |
| 08:41 | Fix a problem with the shell tool EXPLAIN indentation code and VDBE sub-programs. (check-in: 9c8d6856 user: dan tags: trunk) | |
