23:42
Merge the vdbesort.c optimization from trunk. check-in: e4bfffb988 user: drh tags: orderby-planning
23:24
Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. check-in: 01afbf97c0 user: drh tags: orderby-planning
20:01
Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c check-in: 707ea170b3 user: dan tags: trunk
17:41
Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. check-in: 7ce2daafd3 user: drh tags: orderby-planning
16:56
Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. check-in: 62f3a22050 user: drh tags: orderby-planning
15:17
Avoid reusing temporary registers in co-routines when doing block-sorting. check-in: 463d921b51 user: drh tags: orderby-planning
14:30
Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. check-in: b186d8d15a user: drh tags: orderby-planning
14:10
First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. check-in: 59742dd4c5 user: drh tags: orderby-planning
2014-03-18
20:33
Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. check-in: e258df236b user: drh tags: orderby-planning
18:59
Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. check-in: 59d49b7fc4 user: drh tags: orderby-planning
15:30
Experiments with the optimization of ORDER BY and GROUP BY clauses. check-in: b150902579 user: drh tags: orderby-planning
2014-03-17
15:43
Add an experimental multi-threaded capability to vdbesorter.c. check-in: ff0b5c851b user: dan tags: threads
15:06
Clean up some obsolete "register" declarations in printf.c. check-in: ecd9d3f945 user: drh tags: trunk
14:24

19:20
Changes to FTS to ensure that it does not access the database from within the xConnect method. check-in: c67a52c356 user: dan tags: trunk

23:40
Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. check-in: 968fec44d7 user: drh tags: overflow-pgno-cache
20:33
Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. check-in: da59198505 user: dan tags: overflow-pgno-cache

Adjustments to the cost computation for the skip-scan query plan, to take into account the fact that a seek has to occur on each skip. check-in: 0769eebd02 user: drh tags: trunk
18:03
Attempt to work around MSVC's treatment of __LINE__ as a non-constant value in "Edit and Continue" mode by avoiding the use of __LINE__ when SQLITE_VDBE_COVERAGE is not defined. check-in: 0a5318bc27 user: drh tags: trunk
12:20

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
2014-03-06
18:16
Do not run corruptH.test in mmap mode. check-in: c0d54b4e41 user: dan tags: trunk
15:01
Fix a harmless compiler warning in the sessions test harness. check-in: d389e20ab0 user: drh tags: sessions
14:53
Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. check-in: bc0e661033 user: drh tags: sessions

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. The maintains legacy behavior from before the noMemType change. check-in: 1d134ba2ed user: drh tags: trunk
12:47

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.
