20:20 | Clarification of the behavior of sqlite3_stmt_readonly() on BEGIN IMMEDIATE statements. The is comment changes only - no changes to code. (check-in: a4205a83e4 user: drh tags: trunk) | |
19:32 | Remove the OP_RowKey opcode. Use OP_RowData in its place. (check-in: 6ac7b07a4a user: drh tags: trunk) | |
19:18 | Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively. This is a continuation of the optimization started by check-in [2d831074cf]. The result is a slightly smaller and faster binary. (check-in: 49ebc219fa user: drh tags: trunk) | |
