| 19:17 | Fix another fts5 problem caused by a corrupt database. (check-in: 911342f751 user: dan tags: trunk) | |
| 18:00 | Ensure that when a new cursor is opened by OP_OpenDup, any existing cursor with the same id opened by a previous OP_OpenDup is closed first. (check-in: 5c188361a9 user: dan tags: trunk) | |
| 13:59 | Fix another case in fts5 where a corrupt database could cause a buffer overread. (check-in: f7e6cdc562 user: dan tags: trunk) | |

| 21:43 | Fix harmless compiler warnings. (check-in: b57c545a38 user: drh tags: trunk) | |
| 20:39 | Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. (check-in: e130319317 user: drh tags: trunk) | |
| 20:13 | Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization. Put an assert in place of the optimization to detect if the need for this optimization ever returns. (Closed-Leaf check-in: 4fcdc7a293 user: drh tags: reuse-subqueries) | |
| 18:30 | Merge enhancements and bug fixes from trunk. (check-in: 9fb646f29c user: drh tags: reuse-subqueries) | |
| 17:58 | Small changes to the OP_OpenEphemeral opcode to improve testability. (check-in: f856676c84 user: drh tags: trunk) | |
| 16:36 | Fix the OP_OpenEphemeral opcode in the bytecode engine so that if it is called a second or subsequent time, it merely clears the existing table rather than creating a new one. Proposed fix for ticket [d0866b26f83e9c55e30de0821f5d]. (check-in: 4678cb1044 user: drh tags: trunk) | |

| 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) | |

| 21:40 | Merge performance enhancements and other patches. (Leaf check-in: 44e1b55aab user: drh tags: factor-out-scalar-subselect) | |
| 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) | |
| 19:23 | Merge patches and enhancements from trunk. (check-in: da53f3d3ff user: drh tags: reuse-subqueries) | |
| 18:09 | Fix another problem with loading the structure record from a corrupt fts5 database. (check-in: c4d44542d2 user: dan tags: trunk) | |
| 17:45 | Fix a problem causing the sqlite_master entry corresponding to a virtual table to be removed by a DROP TABLE even if the call to the vtabs xDestroy() method failed. (check-in: 0140f6dbfb user: dan tags: trunk) | |
| 16:20 | Add new test file wal2rollback.test to this branch. (check-in: 85a376fc6c user: dan tags: wal2) | |
| 14:33 | Avoid an undefined left-shift operation in fts5 caused by malformed utf-8 text. (check-in: c3a3a11194 user: dan tags: trunk) | |
| 13:57 | Fix a buffer overwrite in fts5 triggered by a corrupt database. (check-in: a385298df2 user: dan tags: trunk) | |

| 16:55 | Modify the btree02.test module so that it does not depend on whether TCL interprets a value as a string or as an integer. (check-in: d9e4f95746 user: drh tags: trunk) | |
| 16:49 | Increase test coverage of wal.c provided by permutation "coverage-wal" on this branch. (check-in: 2f7f893a70 user: dan tags: wal2) | |
| 15:36 | Fix another problem in fts5 caused by a corrupt schema record. (check-in: ff45f9dd69 user: dan tags: trunk) | |
| 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) | |

| 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) | |
