[#MDEV-14299] /usr//bin/wsrep_sst_xtrabackup-v2: line 646: WSREP_SST_OPT

This issue is probably a regression of the work done on ~~MDEV-13968~~.

If your --address doesn't have a port host:port and you don't specify --port WSREP_SST_OPT_PORT will never be set and will result in an unbound variable error on wsrep_sst_xtrabackup-V2 script :

if [ -n "${WSREP_SST_OPT_ADDR_PORT:-}" ]; then

  if [ -n "${WSREP_SST_OPT_PORT:-}" ]; then

    if [ "$WSREP_SST_OPT_PORT" != "$WSREP_SST_OPT_ADDR_PORT" ]; then

      wsrep_log_error "port in --port=$WSREP_SST_OPT_PORT differs from port in --address=$WSREP_SST_OPT_ADDR"

      exit 2

fi

  else

    readonly WSREP_SST_OPT_PORT="$WSREP_SST_OPT_ADDR_PORT"

fi

fi

Possibly we need to move the else block to the outer if:

if [ -n "${WSREP_SST_OPT_ADDR_PORT:-}" ]; then

  if [ -n "${WSREP_SST_OPT_PORT:-}" ]; then

    if [ "$WSREP_SST_OPT_PORT" != "$WSREP_SST_OPT_ADDR_PORT" ]; then

      wsrep_log_error "port in --port=$WSREP_SST_OPT_PORT differs from port in --address=$WSREP_SST_OPT_ADDR"

      exit 2

fi

fi

else

  readonly WSREP_SST_OPT_PORT="$WSREP_SST_OPT_ADDR_PORT"

fi
