| 10:55 | Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. (Leaf check-in: c81f260c2d user: drh tags: analyze-empty-tables) | |

| 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: e972a38608 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: 69ae688982 user: dan tags: trunk) | |

| 14:26 | Optimizations to the Walker object and its methods to make the code a little smaller and to help it run a little faster. (check-in: 6854a34ed7 user: drh 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: 43c9ae371f user: drh tags: trunk) | |
| 03:48 | Improve shell help text for the '.open' command. (check-in: 7cc940a97e user: mistachkin tags: trunk) | |

| 17:27 | Merge the LEFT JOIN query flattener fixes from 3.19.2. (check-in: 6513e4a121 user: drh tags: trunk) | |
| 16:50 | Version 3.19.2 (check-in: edb4e819b0 user: drh tags: release, version-3.19.2, branch-3.19) | |
| 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: 1a074c8a2b user: drh tags: branch-3.19) | |
| 00:28 | The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: b30a364a12 user: drh tags: branch-3.19) | |
| 00:12 | Increase the version number to 3.19.2 since ticket [7fde638e94287d2] is going to necessitate another patch release. (check-in: c315727acd user: drh tags: branch-3.19) | |
