Small tweaks to the query planner to get it to try harder to use an index for sorting and to avoid using automatic indexes on constant terms. Leaf check-in: 2d9de154 user: drh tags: branch-3.8.3

2014-02-06
23:56
Delete the OP_VerifySchema opcode. Enhance OP_Transaction to do the schema version checks that OP_VerifySchema used to do. check-in: 2f3376eb user: drh tags: trunk
14:59
Change more OP_OpenEphemeral operations to OP_OpenHash. Leaf check-in: 881164cf user: drh tags: subquery-codegen-refactor
13:18
Change the spellfix1 virtual table to deterministically names its shadow tables. check-in: 5219cdfc user: drh tags: trunk

Use OpenHash instead of OpenEphemeral for the RHS of IN operators if the result is not needed for sorting. check-in: 715fac77 user: drh tags: subquery-codegen-refactor
02:46
Add additional error messages and a progress spinner to the ".clone" command. check-in: dd0db3f0 user: drh tags: trunk

18:15
Use a new opcode, OP_OpenHash, to indicate that ephemeral tables can be unordered, rather than using the BTREE_UNORDERED bit in the P5 field. check-in: 2997e181 user: drh tags: subquery-codegen-refactor
17:08
Make the root page of an ephemeral index be page 1 instead of page 2. check-in: a332908b user: drh tags: subquery-codegen-refactor

2014-02-04
23:45
Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. check-in: f2504089 user: drh tags: trunk
20:46
Remove the SF_Materialize flag from the SELECT object as it does not accomplish anything useful. check-in: 65d5dcdd user: drh tags: trunk
