50 check-ins occurring around bb6a75f4bbcaaabc.

2014-03-18
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
Performance enhancements and size reduction for sqlite3VXPrintf() (check-in: eb071eb58c user: drh tags: trunk)
2014-03-14
11:46
Fix a harmless compiler warning that crops up with SQLITE_MAX_MMAP_SIZE=0. (check-in: 1277932b7e user: drh tags: trunk)

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)
12:44

Remove a stray C99-style comment. (check-in: f500e87d6e user: drh tags: overflow-pgno-cache)
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)

Forgot to change the VERSION file. (Closed-Leaf check-in: 04caffcef3 user: drh tags: mistake)

2014-03-10
20:12
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
Version 3.8.4 (check-in: 530a1ee7dc user: drh tags: trunk, release, version-3.8.4)

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)
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)
13:48

00:30
Better loadable extension handling in the Win32 VFS when compiled for Cygwin. (check-in: 29b0a4f158 user: mistachkin tags: trunk)
00:28
Better support for MinGW 4.x. (check-in: 170e058520 user: mistachkin tags: trunk)

Merge compiler-warning fixes from trunk. (check-in: a1f2b04285 user: drh tags: sessions)

15:52
Count the number of elements in a SrcList object using an "int" rather than a "u8", to avoid overflows and to work around an issue in the C compiler on AIX. (check-in: eee2a13f2c user: drh tags: trunk)
15:04
Add a test case for the problem fixed by [1d134ba2ed]. (check-in: d4fbc05df9 user: dan tags: trunk)
14:49

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)
