19 check-ins using file src/where.c version bacb79fb

2014-02-07
19:33
Fix redundant definitions of _LARGE_FILE and _LARGEFILE_SOURCE. check-in: 4043d879 user: drh tags: trunk
19:26
In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". check-in: ea4d23d1 user: drh tags: trunk
13:20
Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. check-in: 6fb74485 user: drh tags: coroutine-refactor
03:28
More comment updates. No changes to code. check-in: be24fbc2 user: mistachkin tags: trunk
02:29
Update comments in vdbe.c. No changes to code. check-in: 1122b410 user: drh tags: trunk
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
13:18
Change the spellfix1 virtual table to deterministically names its shadow tables. check-in: 5219cdfc user: drh tags: trunk
02:46
Add additional error messages and a progress spinner to the ".clone" command. check-in: dd0db3f0 user: drh tags: trunk
01:15
Rename the '.repair' shell command to '.clone'. check-in: 4f9d9562 user: mistachkin tags: trunk
00:49
Add the ".repair" command to the command-line shell. check-in: d1dfadea user: drh tags: trunk
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
Rearrange fields in the Parse object for a tighter packing, resulting in an 8% size reduction on x64. check-in: 3e1a3f68 user: drh tags: trunk
2014-02-03
17:04
Performance optimizations in sqlite3PcacheFetch(). check-in: b60cc11e user: drh tags: trunk
14:04
Provide hints to the btree layer Next and Previous primitives to let them know if they can be no-ops if the underlying index is unique. check-in: 6c643e45 user: drh tags: trunk
