| 19:41 | A few simple test cases for the omit-unused-subquery-column optimization. (Closed-Leaf check-in: cf8f57c5 user: drh tags: omit-unused-subquery-columns) | |
| 18:04 | Provide an optimization-disable mask for this optimization. Do not do the optimization if the subquery is an aggregate or is distinct, but allow it to be an ephemeral subquery. Do not omit columns that are used in the ORDER BY of the subquery. (check-in: 6b1a1f37 user: drh tags: omit-unused-subquery-columns) | |
| 15:54 | Do not perform the omit-unused-subquery-columns optimizations on a subquery that is DISTINCT, as that can lead to incorrect results. (check-in: cc148503 user: drh tags: omit-unused-subquery-columns) | |
|
2023-02-15
| ||
| 19:53 | Fix the subquery result column NULL-ifier so that it correctly handles subquery columns past the 63rd column. (check-in: 77b220a7 user: drh tags: omit-unused-subquery-columns) | |
| 17:53 | Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 5dec3cc0 user: drh tags: omit-unused-subquery-columns) | |

| 19:32 | Ignore extra parentheses around a subquery on the RHS of an IN operator, because that is what PostgreSQL does. (check-in: ecdeef43 user: drh tags: trunk) | |
| 18:42 | Do not allow WHERE clause terms to match constant string index terms, which can happen if DQS_DDL is enabled. Follow-up to [44200596aa943963]. dbsqlfuzz 54c9db85ed4af7055f5fd0d50877875c82b11d46. (check-in: 2d2b91cc user: drh tags: trunk) | |

| 12:46 | In the LIKE optimization, do not analyze the new virtual WHERE clause terms until both have been added, since they are expected to be consecutive and the analysis might add complementary terms. This fixes a problem caused by [44200596aa943963] and discovered by dbsqlfuzz and recorded as case 7e3b5983727d843b910b2d9ab556e4afcd777cfb. (check-in: d35de3ad user: drh tags: trunk) | |

|
2023-02-09
| ||
| 15:32 | Disable the double-quoted string misfeature by default in CLI builds. DQS can be reenabled at run-time using the ".dbconfig dqs_dml" and ".dbconfig dqs_ddl" dot-commands. (check-in: c995932c user: drh tags: trunk) | |
| 12:59 | Squelch two harmless signedness comparison warnings in shell.c.in. (check-in: bdd3edec user: stephan tags: trunk) | |

| 20:29 | Back out the 'txn' enhancement to date/time functions. The duration of a "transaction" is confused and needs to be straightened out prior to moving forward with this change. (check-in: 4a145f07 user: drh tags: trunk) | |
| 19:45 | Be careful to maintain the value of 'txn' as long as there are active statements. Withdrawn See the attached Wiki page. (Closed-Leaf check-in: 98d10cb5 user: drh tags: does-not-work) | |

| 12:47 | Add the 'txn' date/time format. Change CURRENT_TIMESTAMP and similar to use 'tnx'-style semantics instead of 'now'-style. (check-in: 61cc8ed8 user: drh tags: trunk) | |
| 12:31 | Test cases to show that CURRENT_TIMESTAMP and similar hold the same value across a transaction. (Closed-Leaf check-in: 7b2fa20e user: drh tags: txn-date) | |
| 12:01 | Revert the behavior of date/time functions with no arguments so that they once again work like 'now', even while CURRENT_TIMESTAMP and similar work like 'txn'. (check-in: 06180caf user: drh tags: txn-date) | |
| 11:34 | Change the behavior of date-time functions without any arguments (and thus the CURRENT_TIME, CURRENT_DATE, and CURRENT_TIMESTAMP variables) so that they work like 'txn' instead of like 'now'. This is an incompatibility with legacy, but brings SQLite into conformance with all other SQL systems. (check-in: 1ac78be5 user: drh tags: txn-date) | |
| 08:49 | Merge wasi-patches branch into trunk. (check-in: 9902e66a user: stephan tags: trunk) | |

|
2023-02-05

| 20:29 | Do not use a Bloom filter if any outer loop lacks STAT1 data, since without STAT1 data, the query planner cannot make an accurate determination of whether or not a Bloom filter will be useful. This fixes the problem reported by forum post 56de336385. (check-in: e6ab96bd user: drh tags: trunk) | |
| 17:40 | Add the "devtest" makefile target that runs both fuzztest and testrunner. (check-in: c81398c6 user: drh tags: trunk) | |
| 17:09 | In fuzzcheck, only show the description of each database if the -v option is specified. (check-in: 6a58179a user: drh tags: trunk) | |
| 00:47 | Restore a test for pBt NULL that was removed by [12a14711afa6cddb] but turned out to be necessary, as dbsqlfuzz quickly showed us. Test case added to TH3. (check-in: 647c89dd user: drh tags: trunk) | |
| 00:32 | Modify the status line output from testrunner so that each line overwrites the previous rather than scrolling. (check-in: ad4d28cd user: drh tags: trunk) | |

| 20:14 | Update testrunner.tcl to use a separate process for each test script. And to run some extra tests too. (check-in: d090948a user: dan tags: testrunner) | |
| 15:41 | Just because a CTE is used more than once, does not mean it should be tagged with M10d_Yes and thereby prohibited from participating in the query flattening optimization. See forum thread 1d571c02963. (check-in: 66f29c40 user: drh tags: trunk) | |
