| 15:57 | For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it.

| 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: fcb7348ba1 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: 8445fb6d5d user: dan tags: wal2) | |

| 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| 20:13 | Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization.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) | |

| 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) | |

| 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) | |

| 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) | |

| 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.

| 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) | |

|
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 reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. (check-in: ad130bb86e user: drh tags: trunk) | |

| 20:14 | Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... (Leaf check-in: 24b0f66ac6 user: drh tags: expr-simplify) | |

| ||
| 23:23 | When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf5e user: drh tags: trunk) | |

Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down.

| 20:37 | Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and make it only work for table btrees. Change sqlite3BtreeDataSize() into sqlite3BtreePayloadSize() and make it work for all btrees. Combine sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single sqlite3BtreePayloadFetch() routine. These changes seem to make the b-tree interface more rational and they reduce both binary size and CPU usage. (check-in: bef35e18dd user: drh tags: btree-refactor) | |

| 21:18 | An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid. The current check-in almost works, but there are still serious issues. (check-in: 49638f180e user: drh tags: without-rowid-vtab) | |

| 16:20 | Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab67 user: dan tags: trunk) | |
