| 20:39 | Shift more OP_Found opcodes over to using the unpacked format, for improved performance. check-in: 6705ab1a user: drh tags: trunk | |
| 19:59 | Enhance the OP_Found and OP_NotFound opcodes so that they can accept an array of registers as an unpacked record in addition to a record built using OP_MakeRecord. Use this to avoid OP_MakeRecord calls during IN expression processing. check-in: b9eab885 user: drh tags: trunk | |
| 17:52 | Factor out the IN operator code generation into a subroutine. Use this subroutine to implement both logic and branching versions of the IN operator. check-in: fcff5b7e user: drh tags: trunk | |
| 13:32 | Factor out the code generator for BETWEEN into a subroutine. check-in: 5735f60b user: drh tags: trunk | |
| 05:04 | Update comment for substrFunc(). Added additional SUBSTR() test cases. check-in: d7b3801d user: shaneh tags: trunk | |
| 04:26 | Suppress unnecessary OP_Noop instructions on when the right table of a LEFT JOIN uses the index-only optimization. check-in: e8aec08b user: drh tags: trunk | |
| 03:46 | Suppress excess OP_Null opcodes caused by binary IS or IS NOT operators that are converted into unary ISNULL or NOTNULL operators. check-in: cff1b36a user: drh tags: trunk | |
| 03:13 | Adjustments to the implementation of LIMIT so that it uses fewer opcodes. check-in: 39d5b292 user: drh tags: trunk | |

| 23:58 | If the sector size is unspecified (initially 0) then set it to 512, not to 32. check-in: 8861b5c1 user: drh tags: trunk | |
| 23:48 | Remove an obsolete (and incorrect) comment from sqlite3MemCompare(). No changes to code. check-in: c15b70b3 user: drh tags: trunk | |
| 20:53 | Tweaks to the SUBSTR() function to make it dramatically faster in the common case where the input string is large but the 2nd and 3rd arguments are small positive integers. check-in: 5a474a86 user: drh tags: trunk | |
| 13:17 | Allow media sector sizes as small as 32. The former minimum size was 512. check-in: 5a32bfc1 user: drh tags: trunk | |
| 04:17 | Modified CLI to raise an error when extra command line options are passed. Added tests to verify correct handling, as well as other basic handling of command line options. Ticket [f5cb008a65]. check-in: 09b4f19f user: shaneh tags: trunk | |
| 01:14 | Additional test cases for the coalesce() and ifnull() functions. check-in: d0591258 user: drh tags: trunk | |
| 00:24 | Generate VDBE code for the built-in COALESCE() and IFNULL() functions. This allows unused arguments to never be evaluated, which is a performance win when the unused argument is a subquery. check-in: 30055b25 user: drh tags: trunk | |
