The original code was mostly rule based and preferred clustered or covering indexed independent of cost. There where a few test changes: - Some test changed from using filesort to index or table scan. This happened when most of the rows had to be sorted and the ORDER BY could use covering or a clustered index (innodb_mysql, create_spatial_index). - Some test changed range to filesort. This where mainly because the range was scanning most of the rows or using index scan + row lookup and filesort with table scan is cheaper. (order_by). - Change in join_cache was because sorting 2 rows is faster than retrieving 10 rows. - In selectivity_innodb.test one test changed to use a cheaper index.
