| 05:20 | Register-ify the OP_AddImm and all casting opcodes. Omit the OP_MemIncr opcode. (CVS 4683) (check-in: 3e8a07dd3c user: drh tags: trunk) | |
| 04:06 | Get rid of OP_Dup, OP_MemStore, OP_MemLoad, and OP_MemMove. Replace with OP_Copy, OP_SCopy, and OP_Move. Add the infrastructure for operation properties in1, in2, in3, out2, and out3 but do not yet use any of these. (CVS 4682) (check-in: cc149eb9ca user: drh tags: trunk) | |

| 04:41 | Add some extra tests for the recent trigger compilation optimization. (CVS 4653) (check-in: de54dad800 user: danielk1977 tags: trunk) | |

|

|
2007-12-29
| ||
| 13:39 | Add experimental pragma "quick_check", a reduced version of integrity_check that runs without most of the overhead of the full integrity_check. (CVS 4645) (check-in: 2ddc8d7272 user: danielk1977 tags: trunk) | |
| 13:18 | Mem3.c enhanced so that an allocation of N bytes only requires (N+11)&~7 bytes instead of (N+15)&~7 bytes of heap storage. Minimum heap usage per allocation is still 16 bytes. 8-byte alignment is preserved. (CVS 4644) (check-in: d027f91cea user: drh tags: trunk) | |
|
2007-12-27
| ||

| 00:02 | Fix some issues with lemon. Tickets #2852 and #2835. (CVS 4641) (check-in: 5283e0d146 user: drh tags: trunk) | |

|
2007-12-17
| ||
| 16:20 | When SQLITE_MAX_SQL_LENGTH is 0, disable the limit. Make the default 0. Once again build the sqlite3 CLI from individual source files so that it can be built on systems that lack tclsh. Tickets #2845 and #2846. (CVS 4636) (check-in: 07aeca3b9c user: drh tags: trunk) | |
