14:40
When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid.

2014-03-03
21:59
Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create a couple of fast-track routines to handle the common cases of a string with BINARY collation or integer values as the left-most column.

2014-03-01
19:45

16:24
Factor the Mem invariant checker into a separate procedure (rather than a macro) so that it can be more easily extended. check-in: 354699d5 user: drh tags: enhanced-mem-check
14:45

2014-02-28
20:47
In the command-line shell add the (undocumented and unsupported) ".eqp" command and -eqp command-line option, to cause EXPLAIN QUERY PLAN to be run on each SQL statement as it is evaluated. Intended use is for analysis of the query planner. check-in: e6ecf733 user: drh tags: trunk

21:35
More efficient removal of duplicates in recursive queries using the UNION compound operator. check-in: 06c2db87 user: drh tags: trunk
19:05
Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch. Leaf check-in: 3ad687b7 user: drh tags: open-only-once
13:53
In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. check-in: 9c2e7612 user: drh tags: trunk

21:01
Attempt to speed up sqlite3VdbeRecordCompare() by various means. This code is in an interim state. check-in: 85206e0b user: dan tags: experimental
19:38
Make sure temporary registers used within a co-routine are not also used outside of that co-routine, in order to prevent concurrent use of the same register for two different things. Ticket [8c63ff0eca81a9132d8] Closed-Leaf check-in: cc5eda54 user: drh tags: tkt-8c63ff0eca
18:12
Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. check-in: 23001a85 user: drh tags: trunk
14:52
QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. check-in: 953cdd6a user: drh tags: trunk
2014-02-24
21:42
Fix several small style/consistency issues with the previous check-in. check-in: 2477b3a2 user: mistachkin tags: trunk

21:20
Enhance testing support for the Win32 VFS dynamic extension loading facilities. check-in: 53081e72 user: mistachkin tags: trunk
19:49
Close some stray connections in walro.test. check-in: d6746cab user: dan tags: trunk
19:07
In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. check-in: ba5f0a55 user: drh tags: trunk
14:24
Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. check-in: 4df0ac90 user: drh tags: trunk
2014-02-21
10:48
Merge updates from trunk. check-in: 09cf240a user: mistachkin tags: winHdr

2014-02-20
19:42

19:32
Fix a harmless shadowed-variable warning. check-in: 82402909 user: drh tags: trunk

2014-02-19
19:14
Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. check-in: c1e94169 user: drh tags: trunk
14:20
Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. check-in: d2c047f3 user: drh tags: trunk
01:31
Make sure a multi-row VALUES clause works correctly in a compound SELECT. check-in: 85b355cf user: drh tags: trunk
00:53
Tweaks in support of VDBE branch test coverage. check-in: b9782564 user: drh tags: trunk
