| 20:47 | Only run preupdate-hook tests in incrblob4.test if the preupdate-hook is enabled in the build. (Leaf check-in: 56314b6b53 user: dan tags: trunk) | |
| 16:19 | Rework the fix to the problem described by forum post b9647a113b so that it provides a more complete fix that covers cases that were not resolved by the original fix, and so that it does not cause performance regressions. (check-in: 28db0d152d user: drh tags: trunk) | |
| 15:40 | Simplifications to the row-value IN operator logic. Do not let the query planner accept a WhereLoop for a row-value IN operator that uses the same index column more than once. (Closed-Leaf check-in: d2adf61f21 user: drh tags: redundant-idx-columns) | |
| 12:11 | Work around the Emscripten 4.10 regression described in Emscripten ticket #24656. Problem reported off-list by BrickViking. (check-in: c385475b25 user: stephan tags: trunk) | |
| 11:37 | Avoid invoking the preupdate hook from within sqlite3_blob_write() if the cursor is already invalid. (check-in: 9f335b9a4e user: dan tags: trunk) | |
| 10:54 | Back out the fix at [ba7d5bad32ad6aac] because it does not always work and because it causes a performance regression. Add new test cases for row-value lookups of indexes that contain redundant columns, three of which are currently failing. This branch is seeking an improved solution to the redundant index column problem for row-value lookups. (check-in: ad8ddcefab user: drh tags: redundant-idx-columns) | |
| 02:18 | Fix parser error introduced by [325e547a2195571e]. See forum post 095dbfc06e5. (check-in: 4eefab4494 user: drh tags: trunk) | |

| 18:32 | Add 'reconfigure' target to Makefile.in to re-run the configure script with the same flags it was generated with. (check-in: c60907e77b user: stephan tags: trunk) | |
| 17:20 | Propagate the -ldl and -lpthread flags, if needed, into sqlite3.pc, per request in forum post 44a58c807353162f. (check-in: 64f5f14322 user: stephan tags: trunk) | |
| 12:25 | Fix harmless compiler warnings. (check-in: 13af4acebe user: drh tags: trunk) | |
| 11:48 | Remove an ALWAYS() added by [960a8e6fc91f4] that turns out to be false in some cases of malformed SQL. (check-in: cc8171461b user: drh tags: trunk) | |
|

| 16:05 | Fix a few cases where LIMIT clauses that were part of scalar sub-queries on virtual tables were not being passed to xBestIndex methods correctly. (check-in: 960a8e6fc9 user: dan tags: trunk) | |
| 15:50 | Improvements to sqlite3_vtab_rhs_value() logging in the ext/misc/vtablog.c extension. (Closed-Leaf check-in: 25131ee84f user: drh tags: vtab-limit-fixes) | |
| 15:32 | Make the value of an explicit LIMIT clause on a scalar sub-query available to xBestIndex for simple "LIMIT 0" and "LIMIT 1" queries. (check-in: 33b6a63caa user: dan tags: vtab-limit-fixes) | |
| 14:28 | Make handling of LIMIT clauses in correlated sub-queries on virtual tables more efficient. (check-in: 7214cb2a5b user: dan tags: vtab-limit-fixes) | |
| 14:10 | Enhancements to the xBestIndex output from the ext/misc/vtablog.c extension. (check-in: 8b31acc0b1 user: drh tags: trunk) | |
| 11:52 | Fix an uninitialized variable added yesterday by [d27d34fb746280e7]. This problem was discovered overnight by OSSFuzz. (check-in: 6db4703f11 user: drh tags: trunk) | |
|

| 11:47 | Improve the bytecode for joins such that it exits earlier if it determines that no output is possible. (check-in: 2d2b61cba4 user: drh tags: trunk) | |
| 02:03 | Ensure that Expr.op2 values for TK_AGG_FUNCTION nodes are adjusted when query flattening. (check-in: d27d34fb74 user: drh tags: trunk) | |
|

| ||
| 23:17 | Improved comments on bytecode used to implement aggregate queries, to aid in debugging. (check-in: a1a8b85cdb user: drh tags: trunk) | |
| 20:32 | Improved byte-code comments for the short-circuit optimization of [0083d5169a46104a], to aid in debugging. (check-in: 113f9d10e3 user: drh tags: trunk) | |
| 17:36 | Cache and reuse virtual table cursors in the bytecode engine. (check-in: 2d187d4232 user: drh tags: trunk) | |
| 16:21 | Avoid an assert() failure in fts5 that may occur when processing corrupt records. (check-in: 8afd6ca857 user: dan tags: trunk) | |
| 15:13 | Merge trunk fixes into the empty-table-optimizations branch. (Closed-Leaf check-in: 63306e447e user: drh tags: empty-table-optimizations) | |
| 12:43 | When attempting to optimize "expr AND false" to "false" and "expr IN ()" to "false", take care not to delete aggregate functions in the "expr" as doing so can change the meaning of the query. See forum thread f4878de3e7. (check-in: 77397bd67d user: drh tags: trunk) | |

| 21:07 | More aggressive optimization of addrHalt for RIGHT JOIN. (check-in: 5e51d1c0df user: drh tags: empty-table-optimizations) | |
| 20:19 | Compute WhereLevel.addrBrk and .addrHalt early so that those labels can be used to abort loops early. Use this to improve performance on two more of the cases described by forum post 52651713ac. (check-in: 6fc0b9ac23 user: drh tags: empty-table-optimizations) | |
| 16:41 | Strive to skip the evaluation of scalar subqueries that are part of a larger expression if the result from the scalar subquery does not change the result of the overall expression. (check-in: 0083d5169a user: drh tags: trunk) | |
| 12:14 | For all binary operators, try to avoid computing subquery operands if the other operand is NULL. (Closed-Leaf check-in: d86eb16283 user: drh tags: optimize-null-values) | |
| 11:04 | Slightly smaller and faster version of the previous check-in. (check-in: f6e6fd02f4 user: drh tags: optimize-null-values) | |
| 11:00 | Minor API doc typo fixes from brickviking. (check-in: b48d951916 user: stephan tags: trunk) | |
