to *not* use the STL as well as removing the STL use from the error handler
routines. This was removing the STL from the C++ bindings (Solaris has 2
versions of the STL; if OMPI uses one and an MPI application wants to use
another, Bad Things happen).
The main idea is to wrap up the C++ callback function pointers and the user's
extra_state into our own struct that is passed as the extra_state to the C
keyval registration along with the intercept routines in intercepts.cc. When the
C++ intercepts are activated, they unwrap the user's callback and extra state
and call them.

It got a little more complicated than that, however:
* I realized that we were returning errors back from
Comm::create_keyval() incorrectly, so I fixed that.
* Instead of using STL maps to store associations, we now use an
opal_list_t which has to be guaranteed to be initialized correctly
and only once in a multi-threaded environment.
* Because of whackyness in the C++ bindings, it is possible to call
Comm::Create_keyval with C callbacks (!). If both registered
callbacks are C functions, then ensure to avoid all the C++
machinery.

* Improve MPI API argument checking by also checking for NULL values
(especially helps when invalid Fortran MPI handles are passed,
because the various MPI_*f2c functions are supposed to return an
"invalid" MPI handle [meaning NULL] when this happens). So now
OMPI will generate an MPI exception rather than a segv.
* Removed a few redundant DATATYPE_NULL checks.
* Also check for some other forms of "invalid" handles (e.g., already
been freed, etc.) in some cases. We could probably be a bit more
stringent in this regard if we really wanted to.
* Change MPI_Get_processor_name to zero out the string up to

the string must be at least that long. We were already passing

The C++ bindings were not tracking keyvals properly -- they were
freeing some internal meta data when Free_keyval() was called, not
when the keyval was actually destroyed (keyvals are refcounted in the
C layer, just like all other MPI objects, because they can live for
long after their corresponding Free call is invoked). This commit
fixes this problem and several other things:
* Add infrastructure on the ompi_attribute_keyval_t for an "extra"
destructor pointer that will be invoked during the "real"
constructor (i.e., when OBJ_RELEASE puts the refcount to 0). This
allows calling back into the C++ layer to release meta data
associated with the keyval.
* Adjust all cases where keyvals are created to pass in relevant
destructors (NULL or the C++ destructor).
* Do essentially the same for MPI::Comm, MPI::Win, and MPI:Datatype:
* Move several functions out of the .cc file into the _inln.h file
since they no longer require locks
* Make the 4 Create_keyval() functions call a common back-end
keyval creation function that does the Right Thing depending on
whether C or C++ function pointers were used for the keyval
functions. The back-end function does not call the corresponding
C MPI_*_create_keyval function, but rather does the work itself
so that it can associate a "destructor" callback for the C++
bindings for when the keyval is actually destroyed.
* Change a few type names to be more indicative of what they are
(mostly dealing with keyvals [not "keys"]).
* Add the 3 missing bindings for MPI::Comm::Create_keyval().
* Remove MPI::Comm::comm_map (and associated types) because it's no
longer necessary in the intercepts -- it was a by-product of being
a portable C++ bindings layer. Now we can just query the C layer
directly to figure out what type a communicator is. This solves
some logistics / callback issues, too.
* Rename several types, variables, and fix many comments in the
back-end C attribute implementation to make the names really
reflect what they are (keyvals vs. attributes). The previous names
heavily overloaded the name "key" and were ''extremely''
confusing.

Please note: the testcode attached to the bug 683 still reports some bugs. I
am however pretty sure that the testcode is wrong at that points:
- the standard says that the attribute MPI_LASTUSEDCODE has to be updated for
a new error_class or a new error_code. The test currently assumes, that only
the add_error_code call changes the attribute value.
- you have to comment out the two lines 73 and 74 in order to make the
test finish, since these lines check for the error string of non-existent
codes.
- line 126 the error-string of MPI_ERR_ARG is not "invalid argument" but a
little bit more, so the test thinks the output is wrong. So probably the test
has to be update to match the according error string of MPI_ERR_ARG.

one request with a non-MPI_SUCCESS value for MPI_ERROR.
* Defer the freeing of requests upon exception in the back-end
functions to MPI_WAIT* and MPI_TEST* until later; the requests are
kept so that we know what handler to invoke when we actually invoke
the exception. After figuring that out, ''then'' we free requests
with pending exceptions on them.
* Clean up return codes from the back-end MPI_TEST* and MPI_WAIT*
functions.
* Slightly modify ompi_errcode_get_mpi_code() to return unity if it
receives an MPI error code (vs. an OMPI error code).

- according to MPI-2 the attribute MPI_LASTUSEDCODE has to be updated
everytime you add a new code or a new class. Thus, you have to have single

Thus, we got rid of the error_class structure. In the error-code structure, we
can distinguish whether we are dealing with an error code or an error class by
looking at the err->code element of the structure. In case its value is
MPI_UNDEFINED, the according entry is a class, else it is an error code. All
predefined error codes have the code and the class field set to the same
value.

The following Trac tickets were found above:
Ticket 624 --> https://svn.open-mpi.org/trac/ompi/ticket/624
(all versions up to and including 20060925). The issue has been
reported to Intel, along with a small [non-MPI] test program that
reproduces the problem (the test program and the OMPI C++ bindings
work fine with Intel C++ 9.0 and many other C++ compilers).
In short, a static initializer for a global variable (i.e., its
constructor is fired before main()) that takes as an argument a
reference to a typedef'd type will simply get the wrong value in the
argument. Specifically:
{{{
namespace MPI {
Intracomm COMM_WORLD(MPI_COMM_WORLD);
}
}}}
The constructor for MPI::Intracomm should get the value of
&ompi_mpi_comm_world. It does not; it seems to get a random value.
As mandated by MPI-2, annex B.13.4, for C/C++ interoperability, the
prototype for this constructor is:
{{{
class Intracomm {
public:
Intracomm(const MPI_Comm& data);
};
}}}
Experiments with icpc 9.1/20060925 have shown that removing the
reference from the prototype makes it work (!). After lots of
discussions about this issue with a C++ expert (Doug Gregor from IU),
we decided the following (cut-n-paste from an e-mail):
-----
> So here's my question: given that OMPI's MPI_<CLASS> types are all
> pointers, is there any legal MPI program that adheres to the above
> bindings that would fail to compile or work properly if we simply
> removed the "&" from the second binding, above?
I don't know of any way that a program could detect this change. FWIW,
the C++ committee has agreed that implementation of the C++ standard
library are allowed to decide arbitrarily between const& and by-value.
If they don't care, MPI users won't care.
When you remove the '&', I suggest also removing the "const". It is
redundant, but can trigger some strange name mangling in Sun's C++
compiler.
-----
So with this change:
* we now work again with the Intel 9.1 compiler
* our C++ bindings do not exactly conform to the MPI-2 spec, but
valid/legal MPI C++ apps cannot tell the difference (i.e., the
functionality is the same)
This commit was SVN r12514.
* Add MPI::Status methods Set_elements() and Set_cancelled()
* Added a bunch of comments in various places in the MPI C++ bindings
implementatio just to explain what's going on (because C++ can hide
a lot from you)
* Insert C++ callbacks for the MPI_Grequest callback functions
registered by MPI::Grequest::Start(). These callbacks keep a
little meta-data (created by Grequest::Start()) that allow the
proper callback signatures from C (i.e., from ompi_grequest_<foo>()
in libmpi.a -- C code), translate arguments as required, and then
invoke the callbacks with proper C++ signatures (i.e., call
user-defined callbacks with C++ function signatures).

Had group discussion about this on the weekly call. The decision was
that we should pass the real error code to the back-end exception
handler because it's pretty useless to pass MPI_ERR_IN_STATUS to the
back-end exception handler (because exception handlers don't have
access to the request or the status - this has potential issues for
fault tolerance kinds of scenarios). So in TESTALL, TESTSOME,
WAITALL, and WAITSOME, we examine the error code and if it's not
MPI_SUCCESS, return MPI_ERR_IN_STATUS.

This commit essentially caches the invoking comm/win/file on the
ompi_request_t. This, paired with the req_type field, allows us to
retrieve the invoking MPI object and invoke the proper errhandler.
The patch is missing most updates for the MPI-2 one-sided stuff (i.e.,
the patch mainly fixes comms and files); I didn't really understand
that code and didn't want to hazard trying to figure it out when Brian
can probably do it much more quickly.
So #250 will still stay open, pending MPI-2 one-sided updates for this
stuff.

* Create a new request type: NOOP (described below)
* For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its
type to NOOP
* Ensure that the NOOP requests are OBJ_RELEASE'd when they are done
* MPI_START looks at the request type; if NOOP, just return success. If
not, call the PML start() function
* MPI_STARTALL always pass the entire array of requests back to the PML
(see next point)
* Make the PMLs only process PML requests (i.e., ignore/skip anything
that isn't of type PML -- such as the NOOP requests)
* Add a little more param error checking in STARTALL

allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).
