Simplify handlerton::drop_database for InnoDB

    XMLWordPrintable

    Details

      Description

      The implementation of handlerton::drop_database in InnoDB is unnecessarily complex. The minimal implementation should check that no conflicting locks or references exist on the tables, delete all table metadata in a single transaction, and finally delete the tablespaces.

      Note: DROP DATABASE will delete each individual table that the SQL layer knows about, one table per transaction. The handlerton::drop_database is basically a final cleanup step for removing any garbage that could have been left behind in InnoDB due to some bug, or not having Atomic DDL (MDEV-17567) in the past.
