whenever possible, partitioning should use the full partition plugin name, not the one byte legacy code. Normally, ha_partition can get the engine plugin from table_share->default_part_plugin. But in some cases, e.g. in DROP TABLE, the table isn't opened, table_share is NULL, and ha_partition has to parse the frm, much like dd_frm_type() does. temporary_tables.cc, sql_table.cc: When dropping a table, it must be deleted in the engine first, then frm file. Because frm can be the only true source of metadata that the engine might need for DROP. table.cc: when opening a partitioned table, if the engine for partitions is not found, do not fallback to MyISAM.
