Ensure each ALTER TABLE statement makes just a single SQLITE_ALTER_TABLE call to the authorizer function. (Leaf check-in: dac28547 user: dan tags: alter-auth-callbacks)
13:46
Add test cases and assert() statements to ensure that the authorizer is being called as expected from within ALTER TABLE. (check-in: ff10d2c7 user: dan tags: trunk)

When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half. This is one proposed fix for ticket [e8b674241947eb3ba4] (Leaf check-in: 5c243eec user: drh tags: unique-constraint-weights)

The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. (Leaf check-in: 857a1b01 user: drh tags: query-planner-debug)

Add an ALWAYS on an unreachable branch in the ALTER TABLE logic. (check-in: ebcd4523 user: drh tags: trunk)

Change a type in shell.c.in from "int" to "sqlite3_int64" in order to avoid a compiler warning and possible integer overflow. (check-in: bf0a6634 user: dan tags: trunk)
