somewhat tied together and I'd rather have a consistent commit rather
than several smaller commits that individually break the tree:
- first cut of src/file/file.c: MPI_File handling. More to come here.
- tweaked MPI_Info handling a bit: cause MPI_Info_f2c to invoke error
handler if provided index is out of range (vs. returing
MPI_INFO_NULL without invoking an error handler)
- moved general MPI MCA params off into their own .h and .c file (so
that ompi_info can call it and therefore display MPI MCA params)
- first [abbreviated] cut of src/mca/io/base/* -- much more to come
here; stripped down to basics for this commit
- filled in a small number of MPI_File* functions for testing purposes
- updated a bunch of doxygen docs
--> Unresolved questions about MPI_ERRORS_RETURN, MPI_ERRORS_ABORT,
and MPI::ERRORS_THROW_EXCEPTIONS because of vagueness in MPI
standard -- Edgar and I are discussing what to do here
--> Unresolved questions about what to do in a case like this:
MPI_File_open(..., &file);
MPI_File_close(&file);
MPI_File_read(..., &file);
because MPI-2:9.7 says that the default error handler on MPI_File
handles is MPI_ERRORS_RETURN -- we can't even print a warning
here! This certainly violates the Law of Least Astonishment for
MPI users (who certainly expect MPI functions that fail to
complain loudly and to abort by default).
This commit was SVN r2136.
