| 18:12 | Clear the BTCF_ValidNKey flag set if a cursor is moved by sqlite3BtreeInsert(). Fix for [f68dc596c4]. (check-in: a6727eef6d user: dan tags: trunk) | |

| 16:37 | Minor bug fixes and performance enhancement. (check-in: b2aae55958 user: drh tags: materialized-view-reuse) | |
| 15:15 | Initial implementation of an optimization that attempts to reuse the same materialization of a view on a self-join of the view. (check-in: 478c34b9a8 user: drh tags: materialized-view-reuse) | |
| 14:25 | Update this branch with latest trunk changes. (check-in: 11f4761c3a user: dan tags: schemalint) | |

| 20:53 | Automatically transfer terms from the HAVING clause to the WHERE clause of an aggregate query in cases where the result of evaluating the term depends only one one or more of the GROUP BY expressions (and on no other inputs). (check-in: 5375a3ce56 user: dan tags: having-where-optimization) | |
| 19:29 | Add a single testcase() macro to the subquery processing logic. (check-in: 4e1df76e3d user: drh tags: trunk) | |

| 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) | |

| 19:59 | Within a loop that uses a non-covering index test, test non-indexed terms that can be tested without seeking the main table cursor before those that cannot. (check-in: afe68f0a80 user: dan 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) | |

| 16:14 | Bring in all the latest enhancements from trunk. (check-in: 031feebc94 user: drh tags: apple-osx) | |
| 14:16 | When building an ephemeral table of integers, do not assume that the table does not already contain N if the insert cursor points to N-1. Fix for ticket [61fe9745]. (check-in: 1c1b086223 user: dan tags: trunk) | |
|
2017-04-22
| ||
| 00:20 | Fix an assertion fault found by OSSFuzz. (check-in: e39769f442 user: drh tags: trunk) | |
|

| ||
| 19:58 | Another minor formatting fix. (check-in: 9fa2ce3c2b user: dan tags: schemalint) | |
| 19:56 | Fix formatting errors in the previous commit. (check-in: da9a2e5aa9 user: dan tags: schemalint) | |
| 19:53 | Update the README.md file in the ext/expert/ directory. (check-in: 3b2ff4e069 user: dan tags: schemalint) | |

| 17:35 | Merge latest trunk changes into this branch. (check-in: b1533bc455 user: dan tags: schemalint) | |
| 17:03 | Avoid creating a temp table in the user database in the sqlite3_expert code. (check-in: 4e36699643 user: dan tags: schemalint) | |
| 16:43 | Speed this branch up a bit by filtering before the virtual table layer when sampling user data. (Closed-Leaf check-in: 8e57c31340 user: dan tags: schemalint-failure) | |
| 16:18 | Avoid adding INTEGER PRIMARY KEY columns to candidate indexes. (check-in: 4577fea5cd user: dan tags: schemalint) | |
| 16:08 | Avoid creating a temp table in the user database in the sqlite3_expert code. Trouble is, this makes sampling for stat1 data much slower. (check-in: c62e358243 user: dan tags: schemalint-failure) | |
| 09:54 | Add an option to generate stat1 data based on a subset of the user database table contents to sqlite3_expert. (check-in: c69c3e21db user: dan tags: schemalint) | |

| 20:10 | Have sqlite3_expert_analyze() populate the sqlite_stat1 table before running queries through the planner for the second time. (check-in: a157fcfde5 user: dan tags: schemalint) | |
| 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) | |
| 17:03 | Add support for analyzing trigger programs to the sqlite3_expert code. (check-in: 159e8022a9 user: dan tags: schemalint) | |
