2019-01-02
| ||
| 23:49 | Fix harmless compiler warnings in the unicode2 logic of FTS3 and FTS5. check-in: 703029ac user: drh tags: trunk | |
| 19:46 | Merge changes from begin-concurrent-wal2. Also modify the unix-excl shm-locks on this branch so that it is not an error to attempt to release an EXCLUSIVE lock that is not held. check-in: 86685679 user: dan tags: begin-concurrent-pnu-wal2 | |
| 17:08 | Reinstate assert() statements in os_unix.c that were removed to allow wal-mode SHARED locks to be taken over more than one locking slot (this branch no longer does that, so the assert() statements can go back in). check-in: fcb7348b user: dan tags: begin-concurrent-wal2 | |
| 17:00 | Reinstate assert() statements in os_unix.c that were removed to allow wal-mode SHARED locks to be taken over more than one locking slot (this branch no longer does that, so the assert() statements can go back in). check-in: 8445fb6d user: dan tags: wal2 | |

| ||
| 21:43 | Fix harmless compiler warnings. check-in: b57c545a 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: e1303193 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| 20:13 | Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization.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: 4fcdc7a2 user: drh tags: reuse-subqueries | |
| 18:30 | Merge enhancements and bug fixes from trunk. check-in: 9fb646f2 user: drh tags: reuse-subqueries | |
| 17:58 | Small changes to the OP_OpenEphemeral opcode to improve testability. check-in: f856676c 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: 4678cb10 user: drh tags: trunk | |

| 16:34 | Increase coverage provided by permutation "coverage-wal" on this branch. check-in: f664f940 user: dan tags: begin-concurrent-wal2 | |
| 14:23 | Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. check-in: 1bdee199 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: 4a0929ac user: drh tags: trunk | |

| 07:46 | Fix a null-pointer dereference that could occur in fts5 with a corrupt database. check-in: b0a49d5e 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: 202dd033 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: 11d4682d user: drh tags: trunk | |

| 16:04 | Fix a problem with handling corrupt databases in the fts5 integrity-check function. check-in: 9bad745d 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: 50e5f390 user: drh tags: factor-out-scalar-subselect | |

| 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: 3c2ad0e9 user: drh tags: reuse-subqueries | |
|
2018-12-24
| ||
| 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: 7153552b 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: 27199380 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: 95a9a39f 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: 06de44ec user: drh tags: reuse-subqueries | |
| 11:55 | Prevent the use of subroutines to implement the RHS of IN operators within CHECK constraints. check-in: 6b24d3fb user: drh tags: reuse-subqueries | |
| 02:34 | Experimental code that tries to put the computation of subqueries inside a subroutine, and reuse that subroutine if the same subquery is evaluated more than once. Current code does not work for CHECK constraints. check-in: 6c44838a user: drh tags: reuse-subqueries | |
|
2018-12-23
| ||
| 21:27 | Split the code generation for the RHS of IN operators and for SELECT and EXISTS expressions into two separate subroutines, because there is now little commonality between those to functions. This is intended to help make the code easier to read and maintain. check-in: 2b6494b1 user: drh tags: trunk | |
