Yes, sorry - that was a typo on my side: it should be INVALID_HANDLE. I think we are all in agreement. Martin On Jul 25, 2013, at 6:29 PM, Anh Vo <[email protected]> wrote:
Yeah, I was a bit confused, too. I agree with Kathryn. Each session has a bunch of handles that were allocated for it, and thus any inquiry should first reference the session, and then the handle. In this case the scope is session2, and handle is not part of session2�s scope, so a search in session2 should not be able to locate the handle, thus MPI_T_ERR_INVALID_HANDLE

I suggested MPI_T_ERR_INVALID_HANDLE not SESSION. Is that what you meant?

Yes, I agree - the handle is invalid in the session referenced in the argument. Therefore MPI_T_ERR_INVALID_SESSION seems reasonable to me.

Hi everybody,
I got asked a question from Nathan:
What should (MPI_T_pvar_read, _write, _reset, etc) return if bad handle is given?
He gave this example of erroneous code: { MPI_T_pvar_session session1, session2; MPI_T_pvar_handle handle; char buffer[256]; int count;
MPI_T_pvar_session_create (&session1); MPI_T_pvar_session_create (&session2);
MPI_T_pvar_handle_alloc (session1, 0, NULL, &handle, &count);
MPI_T_pvar_start (session1, handle);
/* erroneus statement. should return MPI_T_ERR_INVALID_SESSION or MPI_T_ERR_INVALID_HANDLE */ MPI_T_pvar_read (session2, handle, buffer); }
I argue it should return MPI_T_ERR_INVALID_HANDLE since the session is good, it's just that the handle doesn�t match.
Do you all agree? If so, we should specify it since it's ambiguous. I believe this is an errata item.
