| 22:52 | Do a more thorough job of cleaning traces of the strength-reduced LEFT JOIN. (check-in: 08833dda user: drh tags: join-strength-reduction) | |
| 21:16 | If terms of the WHERE clause require that the right table in a LEFT JOIN not be a null row, then simplify the LEFT JOIN into an ordinary JOIN. (check-in: 5b7abecc user: drh tags: join-strength-reduction) | |
| 19:02 | Fix incorrect testcase labels on two cases in join5.test. No changes to code. (check-in: 4661ac81 user: drh tags: trunk) | |
| 18:08 | Improvements to the HAVING-to-WHERE optimization. The code uses less space and less CPU, and there is now ".selecttrace" output. (check-in: 5ad668d4 user: drh tags: trunk) | |
| 16:56 | For 'zipfile', detect attempts to cause a duplicate entry via UPDATE. Also, fix handling of 'UPDATE OR REPLACE' statements run on zipfile virtual tables. Win32 portability fixes to the 'fileio' extension. Miscellaneous test fixes. (check-in: b36caeca user: mistachkin tags: trunk) | |
| 14:00 | Merge all recent trunk enchancements, and especially the autoincrement write reduction fix. (check-in: 25790049 user: drh tags: begin-concurrent-pnu) | |
| 13:54 | Remove debugging puts from concurrrent3.test. (check-in: 13b49756 user: drh tags: begin-concurrent) | |
| 13:52 | Merge all recent enhancements from trunk. (check-in: b0c2f760 user: drh tags: begin-concurrent) | |
| 13:44 | Avoid unnecessary write to the sqlite_sequence table when an insert is done into an autoincrement table with an application-specified rowid that is less than the maximum. (check-in: ec7addc8 user: drh tags: trunk) | |
| 13:26 | Add the ability to disable the push-down optimization using the 0x1000 bit of SQLITE_TESTCTRL_OPTIMIZATIONS. Also some documentation fixes and an enhancement to ".eqp full" in the CLI. (check-in: ae34edb7 user: drh tags: trunk) | |
| 13:00 | Remove a debugging statement accidently left in check-in [eddc35f3057e59fd] (Closed-Leaf check-in: 85a31557 user: drh tags: push-down-disable) | |
| 12:04 | In the CLI, avoid extra .selecttrace and .wheretrace output when in ".eqp full" mode. (check-in: 427bbf31 user: drh tags: push-down-disable) | |
| 11:58 | Closer reading of the sqlite3_db_config() documentation show that it is subtly incorrect. This check-in fixes the problem. No code changes. (check-in: 44d90e7f user: drh tags: push-down-disable) | |
| 11:51 | Fix a minor formatting issue on the sqlite3_db_config() documentation. No changes to code. (check-in: 8a439a6d user: drh tags: push-down-disable) | |
