MySQL:版本后-log代表什么

static void set_server_version(void)
{
  char *end= strxmov(server_version, MYSQL_SERVER_VERSION,
                     MYSQL_SERVER_SUFFIX_STR, NullS);
#ifdef EMBEDDED_LIBRARY
  end= my_stpcpy(end, "-embedded");
#endif
#ifndef DBUG_OFF
  if (!strstr(MYSQL_SERVER_SUFFIX_STR, "-debug"))
    end= my_stpcpy(end, "-debug");
#endif
  if (opt_general_log || opt_slow_log || opt_bin_log)
    end= my_stpcpy(end, "-log");          // This may slow down system
#ifdef HAVE_VALGRIND
  if (SERVER_VERSION_LENGTH - (end - server_version) >
      static_cast<int>(sizeof("-valgrind")))
    end= my_stpcpy(end, "-valgrind"); 
#endif
#ifdef HAVE_ASAN
  if (SERVER_VERSION_LENGTH - (end - server_version) >
      static_cast<int>(sizeof("-asan")))
    end= my_stpcpy(end, "-asan");
#endif
}

就代表你开了gernal log/慢查询/binlog 至少其中一种
