14:43
Merge latest trunk changes. (check-in: 4d7057c4 user: dan tags: deferred-open)
2014-02-11

Test case updates to account for the fact that database files are not created until they are first written. (check-in: 8ef97420 user: dan tags: deferred-open)

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: c950d6c4 user: drh tags: trunk)
2014-02-10

Fix a pointless conditional. Add a test case. (check-in: 9367632d user: drh tags: trunk)

18:02
Use the WITH clause to help resolve names for SELECT statements on the left of a compound query. Proposed fix for ticket [31a19d11b97088296a]. (check-in: 67bfd59d user: drh tags: trunk)

2014-02-08
23:20
Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd78 user: drh tags: trunk)
19:12
Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b user: drh tags: trunk)

04:24
Enable constant expression factoring even if no tables are read and no transaction is started. (check-in: a45b8771 user: drh tags: trunk)
01:40
Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea97 user: drh tags: trunk)
2014-02-07
22:21
Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7 user: drh tags: trunk)
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)
19:18
Change the OP_InitCoroutine instruction to jump over the co-routine implementation. (Closed-Leaf check-in: a522f364 user: drh tags: coroutine-refactor)

Get rid of the OP_Undef and OP_IsUndef opcodes in favor of higher-level OP_InitCoroutine and OP_EndCoroutine. (check-in: 1ec0e9dd user: drh tags: coroutine-refactor)
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

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
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)
