58 check-ins using file src/shell.c version 24722d24

2014-06-17
15:13
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)
2014-02-11
14:52
Version 3.8.3.1 (check-in: ea3317a4 user: drh tags: release, version-3.8.3.1, branch-3.8.3)
03:55
Increase the version number to 3.8.3.1. (check-in: 3111df71 user: drh tags: branch-3.8.3)
03:50
Make sure that virtual WHERE-clause terms do not get transformed into real terms when processing set of OR-connected terms. Fix for ticket [4c86b126f22ad]. (check-in: de635e09 user: drh tags: branch-3.8.3)
2014-02-08
13:22
Fix a harmless compiler warning in VS2013. (check-in: 35f2793d user: drh tags: branch-3.8.3)
2014-02-06
14:59
Change more OP_OpenEphemeral operations to OP_OpenHash. (Leaf check-in: 881164cf user: drh tags: subquery-codegen-refactor)
03:31
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)
2014-02-05
19:10
Separate out the code generators for the RHS of an IN operator and for SELECT/EXISTS expressions. (check-in: 61c34ba7 user: drh tags: subquery-codegen-refactor)
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)
11:05
In the Win32 VFS, the winSysInfo variable should be static. (check-in: 4a4dd371 user: mistachkin tags: trunk)
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)
15:55

17:04

14:04

13:58

2014-01-22
19:23
Avoid an extra seek when inserting records into the epheremal index used to ensure that rows returned by UNION recursive queries are unique. (check-in: 72c4b3f0 user: dan tags: trunk)
18:31
Fix harmless compiler warnings. (check-in: dea2ca6a user: drh tags: trunk)

22:25
Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. (check-in: b2671e11 user: drh tags: cte-via-queue)
