|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: 24b0f66ac6 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: e4129cd3a0 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: 147c61a6d4 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: 8849a463d6 user: drh tags: expr-simplify|

|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: 81f25d5c84 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: 02204f8b24 user: drh tags: trunk|
