|
2016-09-30
| ||
| 22:24 | Avoid initializing the column-cache section of the Parse object, since entries in the cache will be initialized as they are used, and avoiding the initial memset() saves many CPU cycles. (check-in: 63cf7eafae user: drh tags: trunk) | |

|
2016-09-29
| ||

| 19:50 | Remove the peep-hole optimization of removing OP_Close opcodes that come before OP_Halt, as the extra work of removing those opcodes uses more cycles than just running them. (check-in: 984a96d796 user: drh tags: trunk) | |
| 19:27 | Size and performance optimization to sqlite3ValueFromExpr() (check-in: 945f82bc44 user: drh tags: trunk) | |

| 00:03 | Fix FTS3 test cases due to the flattener change of the previous check-in. (check-in: 0c8b9b211f user: drh tags: trunk) | |
|
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=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. (check-in: cf7f9e6d5a user: dan tags: trunk) | |
| 12:38 | Inline the relevent parts of sqlite3ExprAlloc() into spanExpr(), for a performance improvement. (check-in: fe89225eab user: drh tags: trunk) | |
|
2016-09-24
| ||
| 17:42 | Omit the LikeOp object from the parser. Change more sqlite3PExpr() calls into sqlite3ExprAlloc() calls. (check-in: 795454a3fa user: drh tags: trunk) | |
| 01:41 | Add -DSQLITE_MAX_EXPR_DEPTH=0 to the --lean option on speed-check.sh. (check-in: a8cb1390fc user: drh tags: trunk) | |
|
2016-09-23
| ||
| 21:36 | 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: 8a6ea455cd 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: afac0709ce user: drh tags: trunk) | |
| 18:13 | New test case for the ORDER BY LIMIT optimization. (check-in: 9a5a489d0d user: drh tags: trunk) | |
