2016-09-26
14:39
When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?".

12:38
Inline the relevent parts of sqlite3ExprAlloc() into spanExpr(), for a performance improvement. check-in: fe89225e user: drh tags: trunk

01:41

Add the EP_Leaf flag bit to the Expr.flags field to indicate Expr nodes that do not have substructure. Use that bit to avoid unnecessary recursion. check-in: 8a6ea455 user: drh tags: trunk
20:59
Use sqlite3ExprAlloc() instead of sqlite3PExpr() for leaf nodes in the expression tree, where appropriate. This is both smaller and faster. check-in: afac0709 user: drh tags: trunk
18:13
New test case for the ORDER BY LIMIT optimization. check-in: 9a5a489d user: drh tags: trunk
18:06

2016-09-22
21:37

18:53
Remove the internal sqlite3CodeOnce() interface, replacing it with a direct call to sqlite3VdbeAddOp0(v,OP_Once). Slightly smaller and faster. check-in: c3774c6a user: drh tags: trunk

18:18
Fix obsolete requirements marks. Add new tests for VACUUM of attached databases. check-in: 2b44f9aa user: drh tags: trunk
17:53
Avoid running vacuum5.test in auto-vacuum mode. check-in: be184bef user: dan tags: trunk
