wsrep_sst_common.sh falsely parses address argument

    XMLWordPrintable

    Details

      Description

      The new (appeared somewhere between version 10.1.24 and 10.1.34) parsing of --address argument in wsrep_sst_common.sh does not produce expected results when the address does not have all the expected components or corresponding number of slashes included.

      I made a test script (just verbatim snippet from the script) to show how the parsing works

      This results into cluster nodes unable to sync using xtrabackup when WSREP_SST_OPT_LSN is set to xtrabackup_sst
