| 20:47 | Merge latest begin-concurrent changes with this branch. (check-in: 1625887c02 user: dan tags: begin-concurrent-wal2) | |
| 20:42 | Fix a problem causing a corrupt pager-cache if an OOM or IO error was encountered while committing a concurrent transacation. (check-in: 48ca30f9d7 user: dan tags: begin-concurrent) | |
| 16:34 | Increase coverage provided by permutation "coverage-wal" on this branch. (check-in: f664f940a7 user: dan tags: begin-concurrent-wal2) | |
| 14:23 | Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199a7 user: drh tags: trunk) | |
| 02:26 | A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac76 user: drh tags: trunk) | |

| 21:32 | Merge performance enhancements from trunk. (check-in: 0f1b9ff9e1 user: drh tags: reuse-subqueries) | |
| 20:48 | Faster allocation of new sqlite3_stmt objects. (check-in: 891f1f7218 user: drh tags: trunk) | |
| 20:14 | Move the nOpAlloc field from Parse into Vdbe to avoid an extra pointer deference on the fast path in sqlite3VdbeAddOp3(). (check-in: 8f10efc29d user: drh tags: trunk) | |

| 16:20 | Add new test file wal2rollback.test to this branch. (check-in: 85a376fc6c user: dan tags: wal2) | |

| 13:52 | Fix the filename normalization in the dbtotxt utility program. (check-in: 29a00a05dd user: drh tags: trunk) | |
| 07:46 | Fix a null-pointer dereference that could occur in fts5 with a corrupt database. (check-in: b0a49d5e6d user: dan tags: trunk) | |
| 02:16 | Fix a problem in which nested CTEs with the same table name trick the code generator into thinking they are the same CTE, which then tries to use the manifest them both into the same transient table. (check-in: 202dd03301 user: drh tags: trunk) | |
| 00:30 | In the treeview debugging output, provide additional details for the Table object associated with each FROM clause term. (check-in: 11d4682d2e user: drh tags: trunk) | |

| 20:42 | Improve testing of the wal.c changes on this branch. (check-in: 63483e22c7 user: dan tags: wal2) | |
| 19:10 | Merge latest trunk changes with this branch. (check-in: 404f9d99d3 user: dan tags: wal2) | |
| 18:34 | Update the coverage-wal permutation to cover branches enabled by SQLITE_ENABLE_SNAPSHOT. (check-in: 6821c61f1d user: dan tags: trunk) | |
| 17:49 | Add a few more test cases to walvfs.test. (check-in: 14a64df36e user: dan tags: trunk) | |
| 16:57 | Avoid an "uninitialized value read" problem in fts5 that can occur with a corrupt database. (check-in: 6cae81cd1f user: dan tags: trunk) | |
| 16:04 | Fix a problem with handling corrupt databases in the fts5 integrity-check function. (check-in: 9bad745d37 user: dan tags: trunk) | |
| 15:04 | Here is the beginnings of an effort to factor out the implementation of scalar subqueries to be implemented as subroutines at the end of the main body of bytecode, after the jump back to the OP_Init opcode. This is an incremental check-in that contains only preliminary changes. (check-in: 50e5f390fb user: drh tags: factor-out-scalar-subselect) | |
| 14:23 | Fix a problem with corrupt fts3 database detection introduced by [27199380]. (check-in: ceeb4fba84 user: dan tags: branch-3.22) | |
| 14:15 | Fix a problem with corrupt fts3 database detection introduced by [95a9a39f]. (check-in: c80bb15b44 user: dan tags: trunk) | |
| 12:50 | Fix a problem with the CSV extension when it uses the "header" option on a real file. (check-in: 7acaed08f9 user: drh tags: trunk) | |

| 00:15 | Increase the number of parameters to sqlite3WhereCodeOneLoopStart() to encourage the compiler to inline that routine within sqlite3WhereBegin(). This gives a performance improvement. (check-in: 3c2ad0e915 user: drh tags: reuse-subqueries) | |
|

| 20:21 | Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. (check-in: 7153552bac user: drh tags: reuse-subqueries) | |
| 20:00 | Add a few more test cases to walfault2.test and walvfs.test. (check-in: 3873941c4f user: dan tags: trunk) | |

| 14:30 | Restore a line of code that was previously commented out for debugging. (check-in: e53781f5bd user: drh tags: reuse-subqueries) | |
| 13:39 | Change the way a comparison used to detect corrupt databases in fts3 is done to avoid potential pointer overflow in 32-bit builds. Cherrypick of [95a9a39ff7]. (check-in: 271993803c user: dan tags: branch-3.22) | |
| 13:34 | Change the way a comparison used to detect corrupt databases in fts3 is done to avoid potential pointer overflow in 32-bit builds. (check-in: 95a9a39ff7 user: dan tags: trunk) | |
| 12:09 | Do not generate subroutines for non-static SELECT and EXISTS expressions. Fix up some test cases to account for the minor changes in EXPLAIN QUERY PLAN output. (check-in: 06de44ec9e user: drh tags: reuse-subqueries) | |
| 11:55 | Prevent the use of subroutines to implement the RHS of IN operators within CHECK constraints. (check-in: 6b24d3fb94 user: drh tags: reuse-subqueries) | |
