Semi-sync Slave Falsely Logs that Master has Semi-sync Disabled

    XMLWordPrintable

Details

    Description

      During testing MDEV-32551, a semi-sync slave will always output the following error when connecting to a master

      [Note] Slave has semi-sync enabled but master server does not. Semi-sync will be activated when master  enables it

      even if the master has semi-sync enabled. The code has a false negation to output the message:

        if (!strcmp(row[1], "ON"))
      		 
          sql_print_information("Slave has semi-sync enabled but master server does "
      		 
                                "not. Semi-sync will be activated when master "
      		 
                                " enables it");

      Note too, the extra space between the words "master" and "enables" which should be removed.
