| 17:30 | Add the SQLITE_STMTSTATUS_MEMUSED opcode to sqlite3_stmt_status() for finding the heap memory usage by a single prepared statement. (check-in: c26cf978 user: drh tags: trunk) | |
| 16:21 | Add the SQLITE_STMTSTATUS_MEMUSED option for sqlite3_stmt_status() that reports the amount of heap memory used for a single prepared statement. (Closed-Leaf check-in: b57d5104 user: drh tags: stmtstatus-memused) | |

| 18:34 | Change sqlite3BtreeNext() and sqlite3BtreePrevious() so that they return SQLITE_DONE if they have already reached the end (or beginning) of the table. This gives a performance increase and size reduction. (check-in: e972a386 user: drh tags: trunk) | |
| 18:14 | Omit a test of codepoint 0x202F (non-break narrow space) from the fts3 ICU tests. Different versions of ICU apparently handle this obscure codepoint slightly differently. (check-in: 69ae6889 user: dan tags: trunk) | |

| 13:09 | Correctly initialize the iSelectId of FROM clause terms that are a self join of a reused materialized subquery. Without this, the EXPLAIN QUERY PLAN output for the query will identify the subquery using the uninitialized (and arbitrary) iSelectId. (check-in: 43c9ae37 user: drh tags: trunk) | |

| 11:39 | The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a user: drh tags: branch-3.19) | |
