| 15:27 | Evaluate WHERE clause terms that reference only the index before evaluating terms that require the table, and thereby avoid seeking the table row if index terms are false. This is called the "push-down" optimization in the MySQL world, we are told. Do not confuse with WHERE-clause push-down. (check-in: d7bb79ed3a user: drh tags: trunk) | |
| 14:56 | Minor size and performance improvements to the push-down optimization. (Closed-Leaf check-in: 91dfb61a1a user: drh tags: pushdown-optimization) | |

|
2017-04-27

| 14:12 | Do not write master journal filenames into server-mode journal files. Use SQLITE_MUTEX_STATIC_APP1 to protect critical sections in server.c. (check-in: 3144ae40d2 user: dan tags: server-edition) | |
| 13:05 | If possible, delete the journal file when a database connection is closed. (check-in: d5b5326df2 user: dan tags: server-edition) | |

| ||
| 17:03 | Remove a NEVER macro for a condition that may be true as of [a47efb7c]. Problem reported by OSSFuzz. (check-in: bdc50d8d12 user: dan tags: trunk) | |
| 16:04 | Fix an FTS5 bug that could cause a prefix-query without a prefix-index on a database that contains delete-markers to return extra, non-matching, rows. (check-in: 840042cb2b user: dan tags: trunk) | |
|
2017-04-19
| ||

|
2017-04-18
| ||
| 13:50 | Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. (check-in: dc2a48020a user: dan tags: trunk) | |
| 11:20 | Improved optimizations of views as the right operand of a LEFT JOIN. (check-in: 41c27bc0ff user: drh tags: trunk) | |

| 23:23 | Defer checking for null in the comparison operators, since that is an uncommon case. (check-in: 5684525613 user: drh tags: trunk) | |
| 20:50 | Do not allow a Mem object to be both NULL and some other type at the same time. (check-in: e698db1956 user: drh tags: trunk) | |
| 18:42 | Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. (check-in: 69f51f838a user: dan tags: trunk) | |
| 18:02 | Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd7b user: dan tags: trunk) | |
| 16:07 | Further improvements to test coverage in fts3. (check-in: 352413eed4 user: dan tags: trunk) | |
