18 check-ins using file src/btree.c version 4195fed5

2014-08-22
21:58
Performance enhancements in the b-tree mutex logic. check-in: 89145306 user: drh tags: trunk
20:35
Combine the pcacheAddToDirtyList() and pcacheRemoveFromDirtyList() routines into a single pcacheManageDirtyList() routine. The resulting binary code is slightly faster and a few bytes smaller. check-in: 6bcf1af6 user: drh tags: trunk
19:12
Revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. Closed-Leaf check-in: 9fe0f075 user: mistachkin tags: winrt
18:48
Performance enhancement in sqlite3PutVarint(). check-in: a929be55 user: drh tags: trunk
18:00
Split the sqlite3Error() routine into sqlite3Error() and sqlite3ErrorWithMsg(), for a slight size reduction and performance increase. check-in: cf561d1f user: drh tags: trunk
15:40
Performance improvement in the printf() logic by avoiding unnecessary stack pointer movement. check-in: f7f2160d user: drh tags: trunk
15:19
Improve the performance and reduce the size of the sqlite3VdbeSerialGet() routine by avoiding the use of stack. check-in: ebc10e46 user: drh tags: trunk
14:56
Handle the 4-byte integer case in the stackless routine. Closed-Leaf check-in: 3f55484e user: drh tags: experimental
14:34
Get the sqlite3VdbeSerialGet() routine to run faster by avoiding the use of local variables. check-in: 8267d821 user: drh tags: experimental
13:22
Change a while-loop into a do-loop in sqlite3VdbeSerialPut() for a small size reduction and performance improvement. check-in: 750bb0a0 user: drh tags: trunk
11:11
Enhance the spellfix extension with the ability to specify a rowid when inserting new rows. check-in: 369c480c user: drh tags: trunk
2014-08-21
20:26
Simplify the interface to the symbol table, saving 600 bytes of code space. check-in: 14b0f561 user: drh tags: trunk
19:11
For sqlite3_win32_is_nt(), assume WinRT is NT-based. check-in: 2f59e71f user: mistachkin tags: winrt
16:09
Merge all recent trunk changes, especially the fix for ticket [369d57fb8e5ccdff06f1], but also the skip-scan improvement and performance improvements in the b-tree code. check-in: 0b9e2c32 user: drh tags: sessions
14:10
Fix a faulty assert() statement. Add comments to clarify the behavior of the sqlite3OpenTableAndIndices() routine in insert.c. Add test cases to verify that the assert() statement is not firing inappropriately. Ticket [369d57fb8e5ccdff06f1]. check-in: 7029b340 user: drh tags: trunk
2014-08-20
23:42
Increase the version number to 3.8.7 check-in: 91594aae user: drh tags: trunk
23:38
Enhancements to skip-scan such that it is operable when a middle column of an index is skipped while the left-most column is constrained in the WHERE clause. check-in: bc985caa user: drh tags: trunk
18:43
A small performance improvement in freeSpace() by special-casing the relatively common case of an empty freelist. check-in: 49f44d35 user: drh tags: trunk
