Merge the recent performance enhancements implemented on trunk into the threads branch. check-in: dfdc900f user: drh tags: threads
11:33
Remove the pager_lookup() function since it is redundant with sqlite3PagerLookup(). check-in: 54164ce4 user: drh tags: trunk
11:20
Change the name of the VdbeMemRelease() macro to VdbeMemReleaseExtern() to more accurately reflect what it does. Performance enhancement to the sqlite3VdbeMemRelease() function. check-in: 3ca5846d user: drh tags: trunk
2014-08-24
02:53
The sqlite3VdbeChangeEncoding() routine goes about 3x faster if the sqlite3VdbeMemTranslate() subroutine is not inlined. check-in: 0c7e1b87 user: drh tags: trunk
01:32
Patch the sqlite3PagerWrite() method in the Pager to run a bit faster. check-in: c63311e2 user: drh tags: trunk
2014-08-23
23:15
Faster implementation of pcache1Fetch() check-in: 0371cc3b user: drh tags: trunk
20:25
Faster implementation of the sqlite3ApiExit() routine. check-in: bd41d394 user: drh tags: trunk
19:42
Another memory allocator performance optimization. check-in: 6da6f46d user: drh tags: trunk
19:08

19:04
Changes to sqlite3ScratchMalloc() that make the entire memory allocation interface a little faster and about 100 bytes smaller. check-in: f83daa16 user: drh tags: trunk
18:17
Make the implementation of the sqlite3_aggregate_context() interface faster for second an subsequent invocations. This helps all aggregate functions to perform better. check-in: 802148f3 user: drh tags: trunk

Performance optimization in the applyAffinity() logic inside the VDBE. check-in: 25f2246b user: drh tags: trunk
2014-08-22
23:33
Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. check-in: ce123b5c user: drh tags: trunk
22:26
Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. check-in: 3eb08439 user: drh tags: trunk

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

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

14:06

13:38
If SQLITE_TEST_REALLOC_STRESS is defined, extend the op-code array used by virtual-machine programs by one element at a time, instead of doubling its size with each realloc(). check-in: 4c291827 user: dan tags: trunk

17:49
Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. check-in: bdaa6947 user: drh tags: trunk
17:25
Fix a buffer overrun in the previous commit. Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. check-in: 299b9570 user: dan tags: query-planner-fix
15:38

Reworking the documentation on integer result codes. This is a comment and documentation change only. There are no changes to code. check-in: 54f1df7b user: drh tags: trunk
2014-08-07
20:42

20:37
Clarify the computation of compatible isOrdered by in the plan solver of the query planner. Closed-Leaf check-in: b5e8fd57 user: drh tags: query-planner-fix
20:25
Remove the extraneous debugging printf() from the previous check-in. check-in: 8f04d2c0 user: drh tags: query-planner-fix
16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. check-in: ec5d84ba user: drh tags: query-planner-fix
