      Update log is removed since 5.0. But we still accept the option.
      The idea is if the user already uses the binlog and the update log,
      we completely ignore any option/variable related to the update log, like

      if the update log did not exist. But if the user uses only the update

      Implementation of the above :
      - If mysqld is started with --log-update and --log-bin,
      ignore --log-update (print a warning), push a warning when SQL_LOG_UPDATE
      is used, and turn off --sql-bin-update-same.
      This will completely ignore SQL_LOG_UPDATE
      - If mysqld is started with --log-update only,
      change it to --log-bin (with the filename passed to log-update,
      plus '-bin') (print a warning), push a warning when SQL_LOG_UPDATE is
      used, and turn on --sql-bin-update-same.
      This will translate SQL_LOG_UPDATE to SQL_LOG_BIN.

      Note that we tell the user that --sql-bin-update-same is deprecated and
      does nothing, and we don't take into account if he used this option or
unknown's avatar
unknown committed
3845 3846
      not; but internally we give this variable a value to have the behaviour
      we want (i.e. have SQL_LOG_UPDATE influence SQL_LOG_BIN or not).
