2017-05-11
| ||
| 12:05 | Change the SQLITE_READ authorization call for unreferenced tables to use an empty string for the column name, as this is less likely to impact legacy authorization callbacks that assume column names are always non-NULL. check-in: 4139953a user: drh tags: trunk | |

| 18:00 | Fix the fts3EvalAverageDocsize() routine so that it returns errors from sqlite3_reset() rather than always returning SQLITE_OK. check-in: 430f539c user: drh tags: trunk | |
| 17:54 | Reuse the same materialization of a view when that view appears in a query more than once, such as in a self-join. check-in: 9e35c89d 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: d7bb79ed user: drh tags: trunk | |
| 14:56 | Minor size and performance improvements to the push-down optimization. Closed-Leaf check-in: 91dfb61a user: drh tags: pushdown-optimization | |

2017-04-20
| ||
| 17:35 | Merge latest trunk changes into this branch. check-in: b1533bc4 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: 8e57c313 user: dan tags: schemalint-failure | |
| 16:18 | Avoid adding INTEGER PRIMARY KEY columns to candidate indexes. check-in: 4577fea5 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: c62e3582 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: c69c3e21 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: a157fcfd 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: dc2a4802 user: dan tags: trunk | |
| 11:20 | Improved optimizations of views as the right operand of a LEFT JOIN. check-in: 41c27bc0 user: drh tags: trunk | |

| 18:42 | Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. check-in: 69f51f83 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: 690870bd user: dan tags: trunk | |
| 17:03 | Add support for analyzing trigger programs to the sqlite3_expert code. check-in: 159e8022 user: dan tags: schemalint | |

| 13:38 | Improve coverage of code in fts3. check-in: 1a08a836 user: dan tags: trunk | |
| 13:18 | Fix the ".column" output mode in the command-line shell so that it correctly counts and formats multi-byte UTF characters. check-in: f508aff8 user: drh tags: trunk | |
|

| 22:41 | In the showwal command-line tool, for unix builds, if the auxiliary argument is of the form "Ntruncate" where "N" is a frame number, then truncate the WAL file after the N-th frame. check-in: 90015df3 user: drh tags: trunk | |
| 22:08 | Add the anycollseq.c loadable extension in etc/misc check-in: d7b9813c user: drh tags: trunk | |

| 15:47 | Merge latest trunk changes into this branch. check-in: 2d0c458e user: dan tags: schemalint | |
| 14:30 | Add header comment for sqlite3_vtab_collation(). check-in: d238694c user: dan tags: schemalint | |
| 14:16 | Fix memory leaks in the code on this branch. Make use of the sqlite3_index_constraint.usage field. Do not try to handle ORDER BY terms with explicit COLLATE clauses - they don't get passed to the vtab layer anyway. check-in: 0cd75a87 user: dan tags: schemalint | |
| 11:53 | In the skip-ahead-distinct optimization, fix a bug in the logic that determines when to invoke the optimization based on sqlite_stat1 statistics. check-in: 89f9e436 user: drh tags: trunk | |
|
2017-04-14
| ||

| 19:44 | Fix some left-over K&R-C constructs in lemon.c. No changes to the core. check-in: a5379905 user: drh tags: trunk | |
| 19:41 | Modify the code in ext/expert/ to use the vtab interface instead of sqlite3_whereinfo_hook(). Remove sqlite3_whereinfo_hook(). check-in: 3bb65850 user: dan tags: schemalint | |
| 19:03 | Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. Closed-Leaf check-in: 3a5860d8 user: drh tags: left-join-view | |
| 17:30 | When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) check-in: f489b5bb user: drh tags: trunk | |
| 17:18 | An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. check-in: 1838a59c user: drh tags: left-join-view | |
| 14:50 | Make USE_FULLWARN=1 the default for MSVC and fix harmless compiler warnings. check-in: 6bf67376 user: mistachkin tags: trunk | |
