Fix the sqlite3ExprDup() function so that it correctly duplicates the Window object list on a Select that contains window functions. Fix for ticket [f09fcd17810f65f717]. check-in: db5ed2268e user: drh tags: trunk

Performance improvement: Avoid using sqlite3WalkerSelectExpr() and sqlite3WalkerSelectFrom() twice, so that the compiler will in-line their implementation. Closed-Leaf check-in: 2b9258b8b0 user: drh tags: ticket-f09fcd17810f

Fix the sqlite3ExprDup() routine so that it makes complete duplications of subqueries containing window functions. check-in: 940174543e user: drh tags: ticket-f09fcd17810f

New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. check-in: a9a3b53264 user: drh tags: ticket-f09fcd17810f

Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions. check-in: f1b18d44ff user: drh tags: ticket-f09fcd17810f

When masking bits off of sqlite3.flags, make sure the mask is 64 bits in size so as not to accidentally mask of high-order bits. check-in: 53d3b169d8 user: drh tags: trunk
