| 14:20 | Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f304 user: drh tags: trunk) | |
| 01:31 | Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cfb4 user: drh tags: trunk) | |
| 00:53 | Tweaks in support of VDBE branch test coverage. (check-in: b978256469 user: drh tags: trunk) | |

| 11:31 | Fix VDBE branch accounting on comparison operators. (check-in: b287520c92 user: drh tags: trunk) | |
| 05:18 | Enhance the Win32 VFS I/O retry logic. (check-in: adba783c70 user: mistachkin tags: winIoRetry) | |
| 03:07 | Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a97d user: drh tags: trunk) | |
| 01:07 | Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools.

| 23:52 | Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. (check-in: a72687699b user: drh tags: trunk) | |
| 22:40 | Add logic to do test coverage measurements on the VDBE code. (Closed-Leaf check-in: ce184c7bb1 user: drh tags: insert-optimization) | |
