Replace handler::primary_key_is_clustered() with handler::ha_is_clustered_key()
This was done to both simplify the code and also to be easier to handle storage engines that are clustered on some other index than the primary key.
No, I don't get it. Old method meant "Check if the key is a clustered and a reference key". Just "clustered" is marked with HA_CLUSTERED_INDEX. So, 1. You've renamed the method but the name does not match the semantics. It is called is_clustering_key() but it really means "clustered AND reference key" 2. What other engine can be where the reference key isn't a primary key? Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org
