# r2667 MySQL changed the behavior to do full table copy when creating PRIMARY INDEX
# r2667 on a non-NULL column instead of calling ::add_index() which would fail (and
# r2667 this is what we were testing here). Before r2667 the code execution path was
# r2667 like this (when adding PRIMARY INDEX on a non-NULL column with ALTER TABLE):
# r2667 
# r2667 mysql_alter_table()
# r2667   compare_tables()  // would return ALTER_TABLE_INDEX_CHANGED
# r2667   ::add_index()  // would fail with "primary index cannot contain NULL"
# r2667 
# r2667 after r2667 the code execution path is the following:
# r2667 
# r2667 mysql_alter_table()
# r2667   compare_tables()  // returns ALTER_TABLE_DATA_CHANGED
# r2667   full copy is done, without calling ::add_index()
# r2667 
# r2667 To enable, remove "# r2667: " below.
