Performance optimization in the applyAffinity() logic inside the VDBE. check-in: 25f2246b user: drh tags: trunk

Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. check-in: ce123b5c user: drh tags: trunk

Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. check-in: 3eb08439 user: drh tags: trunk
