      avoid hang if subset of procs have invalid INFO · 470667cb
      Rob Latham authored
      In response to IBM's integration ticket 1822 (but reworked), turn
      MPIO_CHECK_INFO into a collective macro; exchange result of info
      inspection with all procs.  Now a bogus info on one proc won't cause a
      process hang.

      [svn-r10801] ROMIO: error checking for MPI_Comm and MPI_Info objects · 47754bc5
      David Goodell authored
      1). There was error checking on the comm object in
          MPI_Comm_test_inter(comm, &flag); So if the return value of
          MPI_Comm_test_inter is not MPI_SUCCESS, then the comm is either an
          invalid MPI_Comm handle or intercommunicator handle.
      2). A new macro MPIO_CHECK_INFO is added into adioi_error.h. It will
          call MPI_Info_dup, unless there is no more memory space left , as
          long as the info object is valid, this function will return
          MPI_SUCCESS; or it will return an error code. So by checking the
          return value of MPI_Info_dup, we could achieve the purpose of
          checking MPI_Info handles.
      
      Based on patch 0006 from the second round of IBM's error checking
      patches.  Replaces 0009 from the first round and augments r10637.
