[5375a3ce] 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). (user: dan, tags: having-where-optimization)
19:29
[4e1df76e] Add a single testcase() macro to the subquery processing logic. (user: drh, tags: trunk)
18:02
[e54c9f8d] Improvements to opcode documentation in the bytecode engine. No changes to code. (user: drh, tags: trunk)
15:27
[d7bb79ed] 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. (user: drh, tags: trunk)
14:56
[91dfb61a] Closed-Leaf: Minor size and performance improvements to the push-down optimization. (user: drh, tags: pushdown-optimization)
2017-04-28
19:59
[afe68f0a] 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. (user: dan, tags: pushdown-optimization)

2017-04-18
13:50
[dc2a4802] 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. (user: dan, tags: trunk)
11:20
[41c27bc0] Improved optimizations of views as the right operand of a LEFT JOIN. (user: drh, tags: trunk)
05:49

20:50
[e698db19] Do not allow a Mem object to be both NULL and some other type at the same time. (user: drh, tags: trunk)
18:42
[69f51f83] Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. (user: dan, tags: trunk)
18:02
[690870bd] 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. (user: dan, tags: trunk)
16:07
[352413ee] Further improvements to test coverage in fts3. (user: dan, tags: trunk)
13:38
[1a08a836] Improve coverage of code in fts3. (user: dan, tags: trunk)

2017-04-16
22:41
[90015df3] 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. (user: drh, tags: trunk)
22:08
[d7b9813c] Add the anycollseq.c loadable extension in etc/misc (user: drh, tags: trunk)

19:03
[3a5860d8] Closed-Leaf: 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. (user: drh, tags: left-join-view)
17:30
[f489b5bb] 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.) (user: drh, tags: trunk)
17:18
[1838a59c] 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. (user: drh, tags: left-join-view)
14:50
[6bf67376] Make USE_FULLWARN=1 the default for MSVC and fix harmless compiler warnings. (user: mistachkin, tags: trunk)
14:02
[5159cb8f] Enhance the sqlite3TreeView() display for Expr objects so that it shows the iRightJoinTable value for Expr nodes that have the EP_FromJoin property. (user: drh, tags: trunk)
12:39
[e651074b] Simplify the interface to the subst() routines that are part of the query flattener by collecting common parameters into the SubstContext object and passing around a pointer to that object. (user: drh, tags: trunk)
12:27

[6f54ffd1] Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (user: dan, tags: trunk)
01:19
[132339a1] Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. (user: drh, tags: skip-ahead-distinct)
00:12
[8e7b6118] Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. (user: drh, tags: trunk)
