Case sensitive problem with routines SHOW <P/F> STATUS;

    Details

      Description

      When working with a case sensitive file-system, MariaDB (it also fails in MySQL) allows you to have
      a database with the same name in different cases (example TEST/test).
      This works correctly.
      However, procedures that are related to that database are stored inside
      information_schema.routines associated with ROUTINE_SCHEMA which is a
      case insensitive column.
      This brings a problem, for example, when using mysqldump since when
      listing routines to dump in the line "SHOW %s STATUS WHERE Db = '%s'"
      it would bring procedures from other databases that have the same name
      with different case.
      mysqldump could be modified to use mysql.proc instead which correctly
      has utf8_bin in the Db column, but I'm not sure that would be the best
      to go since this affects anyone using SHOW <P/F> STATUS.

      CREATE DATABASE A;
      USE A;
       
      delimiter //
       
      CREATE PROCEDURE simpleproc()
          BEGIN
             SELECT 1;
          END//
       
      delimiter ;
      CREATE DATABASE a;
      USE a;
       
      SHOW PROCEDURE STATUS WHERE Db = 'a';
      -- Incorrectly shows procedure from A
      SELECT count(*) FROM mysql.proc WHERE Db='a';
      -- Correctly show 0 results
       
      DROP DATABASE A;
      DROP DATABASE a;
