| 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. (Leaf 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) | |

| 15:36 | Remove some dead JS code and some extraneous debug output from test code. (Leaf check-in: 6e73770a7f user: stephan tags: oo1-unowned-handles) | |
| 15:13 | JS doc additions. (check-in: 7933505f0c user: stephan tags: oo1-unowned-handles) | |
| 15:01 | Experimentally add sqlite3.oo1.DB/Stmt.wrapHandle(), which allow DB/Stmt instances to wrap a (sqlite3*)/(sqlite3_stmt*) optionally with or without taking ownership of it. The intent is to enable mix-and-match use of the C API, the oo1 API, and any other hypothetical API which exposes those pointers. oo1.Stmt.parameterCount is now a property access interceptor like Stmt.columnCount is, but that doesn't change how it's used.

| 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) | |
| 10:17 | Merge trunk into column-text-blob-v2 branch. (Leaf check-in: f73460d4f0 user: stephan tags: column-text-blob-v2) | |

| 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) | |
