| 23:15 | Faster implementation of pcache1Fetch() (check-in: 0371cc3bb0 user: drh tags: trunk) | |
| 20:25 | Faster implementation of the sqlite3ApiExit() routine. (check-in: bd41d394d4 user: drh tags: trunk) | |
| 19:42 | Another memory allocator performance optimization. (check-in: 6da6f46d0c user: drh tags: trunk) | |
| 19:08 | Fix a variable-declaration after code problem in btree.c. Harmless in GCC and CLANG but unacceptable for MSVC. (check-in: 45abd5c0ba user: drh tags: trunk) | |
| 19:04 | Changes to sqlite3ScratchMalloc() that make the entire memory allocation interface a little faster and about 100 bytes smaller. (check-in: f83daa16f6 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: 802148f311 user: drh tags: trunk) | |
| 17:41 | Improved performance in the type handling of arithmetic operators in the VDBE. (check-in: 0c0a603950 user: drh tags: trunk) | |

| 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: ce123b5c59 user: drh tags: trunk) | |
| 22:26 | Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. (check-in: 3eb0843903 user: drh tags: trunk) | |
| 21:58 | Performance enhancements in the b-tree mutex logic. (check-in: 8914530644 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: 6bcf1af6a4 user: drh tags: trunk) | |
| 18:48 | Performance enhancement in sqlite3PutVarint(). (check-in: a929be5519 user: drh tags: trunk) | |
| 18:00 | Split the sqlite3Error() routine into sqlite3Error() and sqlite3ErrorWithMsg(), for a slight size reduction and performance increase. (check-in: cf561d1f0b user: drh tags: trunk) | |
| 15:40 | Performance improvement in the printf() logic by avoiding unnecessary stack pointer movement. (check-in: f7f2160db0 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: ebc10e46c1 user: drh tags: trunk) | |
| 14:56 | Handle the 4-byte integer case in the stackless routine. (Closed-Leaf check-in: 3f55484e81 user: drh tags: experimental) | |
| 14:34 | Get the sqlite3VdbeSerialGet() routine to run faster by avoiding the use of local variables. (check-in: 8267d82174 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: 750bb0a096 user: drh tags: trunk) | |
| 11:11 | Enhance the spellfix extension with the ability to specify a rowid when inserting new rows. (check-in: 369c480cda user: drh tags: trunk) | |

| 20:26 | Simplify the interface to the symbol table, saving 600 bytes of code space. (check-in: 14b0f561fe user: drh tags: trunk) | |
| 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: 7029b3404d 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: bc985caa78 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: 49f44d355f user: drh tags: trunk) | |
| 17:56 | Reimplement the freeSpace() routine in btree.c so that it runs faster. (check-in: fe4fd014b4 user: drh tags: trunk) | |

| 11:56 | Further size reduction and performance improvement in btree.c:allocateSpace(). (check-in: 1cb1cd6493 user: drh tags: btree-speedup) | |
| 10:42 | Fix a typo in the showdb usage message. (check-in: 6c66beae97 user: dan tags: trunk) | |
