|21:24||Make sure the WHERE_IDX_ONLY flag is not set on query plans that will not be using an index. (Closed-Leaf check-in: 698b2a28 user: drh tags: fullscan-covering-index)|
|20:44||Add the ability to disable the covering-index-scan optimization at compile-time, start-time, or at run-time. Add test cases to check this configurability. (check-in: ccb8ecc3 user: drh tags: fullscan-covering-index)|
|19:26||Merge recent trunk changes into the fullscan-covering-index branch. (check-in: 1c0bf030 user: drh tags: fullscan-covering-index)|
|19:12||Remove obsolete bits from the bitvector that defines disabled optimizations in the SQLITE_TESTCTRL_OPTIMIZATIONS verb of sqlite3_test_control(). (check-in: 4c21ee2d user: drh tags: trunk)|
|18:56||Remove an unnecessary parameter from sqlite3Utf8Read() resulting in a slight performance increase. (check-in: 8b962c94 user: drh tags: trunk)|
|17:16||Make sure the KeyInfo.aSortOrder array is always allocated so that we never have to test for KeyInfo.aSortOrder==0 in performance-critical loops. (check-in: 45793f0b user: drh tags: trunk)|
|15:36||Performance enhancement in the sqlite3VdbeSerialType() routine. (check-in: ad298f52 user: drh tags: trunk)|
|18:45||Attempt to use a covering index even on a full table scan, under the theory that the index will be smaller and require less disk I/O and thus be faster. (check-in: cfaa7bc1 user: drh tags: fullscan-covering-index)|
|13:39||Make sure the name of rollback journal files are double-zero terminated when they are passed into the VFS. (check-in: 8711a844 user: drh tags: trunk)|
|13:29||Factor out the code that generates a co-routine for evaluating the SELECT on the RHS of an INSERT statement so that the same code can potentially be reused in other places. (check-in: a93ee09c user: drh tags: trunk)|
|19:59||Improved alignment of fields in the Expr object gives an 8-byte size reduction on 64-bit machines. (check-in: 6b252a0d user: drh tags: trunk)|
|16:12||Fix WAL capability checking in one of the test files. (check-in: 0ebe7cc5 user: mistachkin tags: trunk)|
|15:26||Fix an unused variable warning with SQLITE_OMIT_WAL. (check-in: 39866c0e user: mistachkin tags: trunk)|
