[ce123b5c59] Leaf: 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. (user: drh, tags: trunk)
22:26
[3eb0843903] Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. (user: drh, tags: trunk)
21:58
[8914530644f] Performance enhancements in the b-tree mutex logic. (user: drh, tags: trunk)
20:35
[6bcf1af6a4] Combine the pcacheAddToDirtyList() and pcacheRemoveFromDirtyList() routines into a single pcacheManageDirtyList() routine. The resulting binary code is slightly faster and a few bytes smaller. (user: drh, tags: trunk)
18:48
[a929be5519] Performance enhancement in sqlite3PutVarint(). (user: drh, tags: trunk)
18:00
[cf561d1f0b] Split the sqlite3Error() routine into sqlite3Error() and sqlite3ErrorWithMsg(), for a slight size reduction and performance increase. (user: drh, tags: trunk)
15:40
[f7f2160db0] Performance improvement in the printf() logic by avoiding unnecessary stack pointer movement. (user: drh, tags: trunk)
15:19
[ebc10e46c1] Improve the performance and reduce the size of the sqlite3VdbeSerialGet() routine by avoiding the use of stack. (user: drh, tags: trunk)
13:22
[750bb0a096] Change a while-loop into a do-loop in sqlite3VdbeSerialPut() for a small size reduction and performance improvement. (user: drh, tags: trunk)
11:11
[369c480cda] Enhance the spellfix extension with the ability to specify a rowid when inserting new rows. (user: drh, tags: trunk)

20:26
[14b0f561fe] Simplify the interface to the symbol table, saving 600 bytes of code space. (user: drh, tags: trunk)
14:10
[7029b3404d] 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]. (user: drh, tags: trunk)

[91594aae07] Increase the version number to 3.8.7 (user: drh, tags: trunk)
23:38
[bc985caa78] 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. (user: drh, tags: trunk)
18:43
[49f44d355f] A small performance improvement in freeSpace() by special-casing the relatively common case of an empty freelist. (user: drh, tags: trunk)
17:56
[fe4fd014b4] Reimplement the freeSpace() routine in btree.c so that it runs faster. (user: drh, tags: trunk)
14:37
[7e63089a19] Refactor local variable names in the freeSpace() routine of btree.c for improved understandability. (user: drh, tags: trunk)
13:35
[121308fa86] Size reduction and performance improvements in btree.c and the allocateSpace() routine. Also fix an assert() in freeSpace(). (user: drh, tags: trunk)
13:25
[eea0661798] Add SQLITE_API macros in front of interface routines in the test_intarray.c extension. (user: drh, tags: trunk)
10:42
[6c66beae97] Fix a typo in the showdb usage message. (user: dan, tags: trunk)

2014-08-19
23:04
[d280157da0] Modify the memsubsys1-3.1.4 test so that it does not fail arbitrarily due to variations in the behavior of system malloc(). (user: drh, tags: trunk)
20:41
[44d5bd4cc3] A better fix for the sqlite3_trace() problem. Ticket [11d5aa455e0d98f3c1e6a] (user: drh, tags: trunk)
20:27
[0d4d3df4bc] Make sure the sqlite3_trace() callback is invoked, even if the prepared statement was marked "expired" before it ever entered sqlite3_step(). Ticket [11d5aa455e0d98f3c1e6a08]. (user: drh, tags: trunk)
19:28
[d09d63c077] Improvements to output formatting with the ".trace" command in the command-line shell. (user: drh, tags: trunk)
