| 13:13 | Disable the query flattener optimization for SELECT statements that are on the RHS of vector IN operators. This is a hack that fixes the bug described in ticket [da7841375186386c]. A better solution that does not disable the query flattener is needed, but this will server for the time being. (check-in: 005d5b87 user: drh tags: trunk) | |

| 19:01 | Enhance the OP_IdxInsert opcode so that it can used unpacked key values if they are available. Update the code generator to take advantage of this new capability. The speedtest1.c test is about 2.6% faster as a result. Later: This also introduced bug [30027b613b]. Bummer. (check-in: 925840cf user: drh tags: trunk) | |
| 18:19 | Remove obselete and unused logic in the update code generator. Fix the sqlite3BtreeMovetoUnpacked() routine so that it remembers the rowid of the row that it landed on. (Closed-Leaf check-in: 1a587d72 user: drh tags: unpacked-IdxInsert) | |
| 17:52 | Merge enhancements and bug-fixes from trunk. (check-in: 5515b827 user: drh tags: unpacked-IdxInsert) | |
