20:03
Add test script ext/rbu/rbu_round_trip.tcl. Uses "dbselftest" to test that "rbu" and "sqldiff" work together. (check-in: 961e79da73 user: dan tags: trunk)
14:47
Before beginning an incremental checkpoint in RBU, sync the directory containing the target database file. This ensures that the new directory entry created by renaming the *-oal file to *-wal is synced to disk. Cherrypick of [915a9a28]. (Leaf check-in: 694fe0b22b user: dan tags: version-3.17.0-rbu-fixes)
14:46
Fix another RBU case similar to the previous. This one for systems where the sector-size is larger than the page-size. Cherrypick of [4012bb3a]. (check-in: 59a11b7f1f user: dan tags: version-3.17.0-rbu-fixes)
14:45
When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file. Otherwise, if a power failure occurs and the RBU update resumed following system recovery, the database may become corrupt. Cherrypick of [edee6a80]. (check-in: 811a559967 user: dan tags: version-3.17.0-rbu-fixes)
14:38
Performance optimization in the tokenizer/parser loop. (check-in: 2cb71583d6 user: drh tags: trunk)
12:18
Minor comment typo fixes. No changes to code. (check-in: 01cd9fb176 user: drh tags: trunk)
03:40
More size and speed improvements in the expression name resolver. (check-in: e0a3d39f51 user: drh tags: trunk)
03:25
Small size reduction and performance increase in the name resolver routine for expressions. (check-in: 1a3554e1d7 user: drh tags: trunk)

2016-03-07
21:28
Fix a typo and remove an unused variable from test logic. (check-in: 9f31516c5d user: drh tags: apple-osx)
20:48
Merge recent enhancements from trunk. (check-in: 84f09f00f8 user: drh tags: apple-osx)
20:14
Update fts3/4 so that the 'merge=X,0' command merges X pages from all segments of the first level in the fts index that contains 2 or more segments. (check-in: cddf69dbc4 user: dan tags: trunk)
19:08
Avoid a NULL pointer dereference following an OOM while generating code for IN operators on virtual tables. (check-in: c924008692 user: drh tags: trunk)
17:49
Merge the virtual table query planner enhancement, the RTREE cost estimate fix, and the statement journal spill delay enhancement from trunk. (check-in: 17fd8f3cf0 user: drh tags: sessions)
17:39
Add a new row type to RBU (a peer of insert, update and delete) - "delete then insert". (Closed-Leaf check-in: 169311c85b user: dan tags: rbu-delete-then-insert)
17:37
Add the SQLITE_CONFIG_STMTJRNL_SPILL option for sqlite3_config(). (check-in: b6c4202432 user: drh tags: trunk)

20:32
Fix another problem with the LIKE optimization. (check-in: 465bfc72d2 user: drh tags: like-opt-fix)
15:46
Fix some compiler warnings caused by signed/unsigned pointer conversions. (check-in: cccee7b5b1 user: dan tags: fts5)
13:57 Fixed ticket [05f43be8fd]: Incorrect use of index with LIKE operators when the LHS is a blob plus 5 other changes (artifact: c140b281fa user: drh)
13:56
Fix the LIKE optimization so that it finds BLOB entries in addition to text entries. Ticket [05f43be8fdda9f]. (check-in: 74cb0b032f user: drh tags: trunk)
12:58
New test cases for LIKE and GLOB with BLOB left-hand side values. (Closed-Leaf check-in: 50fa3c5fae user: drh tags: like-opt-fix)
11:50
Fix the bm25() function so that it multiplies scores by -1 before returning them. This means better matches have a lower numerical score, so "ORDER BY rank" (not "ORDER BY rank DESC") does what you want. (check-in: 3ee7b5a9f9 user: dan tags: fts5)
03:02
Remove some code that is commented out. (check-in: 55ff429177 user: drh tags: like-opt-fix)
02:51
Fix problems with reverse order sorting and indexes in the LIKE optimization. (check-in: 564b8fe794 user: drh tags: like-opt-fix)
00:57
Refactor some jump opcodes in the VDBE. Add JumpZeroIncr and DecrJumpZero. Fix the LIKE optimization to work with DESC sort order. (check-in: 26cb5145bf user: drh tags: like-opt-fix)

2014-03-07
14:57
Improved comment on the pager.c PERSIST rollback journal delete logic inside of hasHotJournal(). No changes to code. (check-in: e5b17a9d07 user: drh tags: trunk)
14:36
Merge the fix for the journal_mode=PERSIST error recovery delay bug. (check-in: bb6a75f4bb user: drh tags: sessions)
03:31
Revise change from the previous check-in to clarify the situation when handling open journal files, regardless of journal mode. (check-in: 1c318ef3b7 user: mistachkin tags: trunk)
02:29
Avoid calling sqlite3OsDelete() on a file that is open, since this causes Windows to run *very* slowly. Comes up on error recovery in journal_mode=PERSIST. (check-in: fdc651e2ec user: mistachkin tags: trunk)

2013-03-07
14:00
Fix the char() function so that it works even if SQLITE_OMIT_UTF16 is defined. (check-in: af542c82e8 user: drh tags: trunk)
11:03
Avoid an assertion fault and/or freeing memory while it is still in use when an error occurs during virtual table construction. Cherrypick of [a02599ad85d]. (check-in: 760072ceea user: dan tags: branch-3.7.14)
09:39
Skip tests that require UTF-16 support when compiled with SQLITE_OMIT_UTF16. (check-in: e39391422e user: mistachkin tags: trunk)
06:42
Fix two compilation issues, one warning and one error, that occur only when SQLITE_OMIT_UTF16 is defined. (check-in: 10ace06be7 user: mistachkin tags: trunk)

Make sure all necessary mutexes are held prior to initializing the schema in sqlite3_table_column_metadata(). (CVS 4841) (check-in: 4996ff9357 user: drh tags: trunk)
21:04
Fix an alignment problem in test_async.c. (CVS 4840) (check-in: 752d8e21bb user: drh tags: trunk)
20:14
Another fix to the OsUnlock I/O error logic. (CVS 4839) (check-in: 22bd537ee2 user: drh tags: trunk)
19:51
Correctly handle I/O errors that occur during OsUnlock(). Before this fix, an I/O error during OsUnlock() could lead to database corruption. That is not a serious problem, though, since errors during OsUnlock() are not possible on most systems. (CVS 4838) (check-in: b4c1258edb user: drh tags: trunk)
15:34
Cleanup the locking-style code in os_unix.c. (CVS 4837) (check-in: 40f55c09db user: drh tags: trunk)

00:27
Updates to the locking-style code in os_unix.c. Not yet working. (CVS 4834) (check-in: 6ebce3b798 user: drh tags: trunk)
