11 check-ins related to "expr-simplify"
|20:14||Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... (Leaf check-in: 24b0f66a user: drh tags: expr-simplify)|
|17:24||Fix an issue in virtual table handling associated with the new Expr.x.pRight field. (check-in: 8487f84a user: drh tags: expr-simplify)|
|16:35||Make sure Expr.eX changes back to EX_None after Expr.x.pRight is set to NULL due to an OOM. (check-in: e4129cd3 user: drh tags: expr-simplify)|
|14:54||Reduce the size of Expr from 80 to 72 bytes moving the pRight field inside the "x" union. This is an incremental check-in that still has issues. (check-in: 147c61a6 user: drh tags: expr-simplify)|
|11:59||Make sure temporary Expr objects are fully initialized prior to sending them into sqlite3ExprCodeTemp(). (check-in: de02a1d9 user: drh tags: expr-simplify)|
|21:35||In the Expr object, the Expr.eX field determines what value is stored in the Expr.x union. This mostly works, but there are issues identified by valgrind. (check-in: 8849a463 user: drh tags: expr-simplify)|
|18:08||Merge all recent trunk enhancements. (check-in: 655f0654 user: drh tags: expr-simplify)|
|17:50||Avoid incrementing the SQLITE_LOOKASIDE_MISS_SIZE stat before sqlite3_open() returns. Fix test script problem in lookaside.test. (check-in: e461cb28 user: dan tags: trunk)|
|13:37||An early attempt at refactoring Expr (Closed-Leaf check-in: fc90a53d user: drh tags: expr-simplify-branch1)|
|01:30||Add assert() statements to sqlite3ExprDelete() that prove various symmetry properties of the Expr object that might be exploited to make the Expr object smaller and faster. (check-in: 81f25d5c user: drh tags: expr-simplify)|
|23:33||Improvements to the parser to increase coverage. Fix the parser so that at least one expresssion is required after PARTITION BY and within the list of expressions on VALUES(). (check-in: 02204f8b user: drh tags: trunk)|
