mariadb-hotcopy requires '--port' set for operation since 10.11

Details

    Description

      As I described here on Zulip,
      I keep hitting this problem with MariaDB 10.11 on Fedora / RHEL.

      mysql <<< "CREATE DATABASE db1; USE db1; CREATE TABLE test_table1 (f1 INT, f2 INT) ENGINE=MyISAM; INSERT INTO test_table1 VALUES (111, 222);"
      		 
       
      		 
      mysql -D db1 -e "SELECT * FROM test_table1;"
      		 
       
      		 
      mysql -D brand_new_db1
      		 
       
      		 
      mysqlhotcopy db1 brand_new_db1

      returns:

      ERROR 1049 (42000): Unknown database 'brand_new_db1'
      		 
      Argument "" isn't numeric in subroutine entry at /usr/lib64/perl5/vendor_perl/DBD/MariaDB.pm line 140.
      		 
      DBI connect(';host=;port=;mariadb_read_default_group=mysqlhotcopy','',...) failed: Connection error: port is not valid number at /usr/bin/mysqlhotcopy line 222.

      It only works in MariaDB 10.11 when --port is specified. (but without --host, which contradicts this)
      In MariaDB 10.5 it works without the need to specify the port.

      Sergei Golubchik said in the Zulip coversation it is likely a bug, not an expected change, so I'm reporting it as such.
