[[ flipping the order of Andre's remarks ]]
Making a copy of the context does not help. The problem, as said, is that the 'remove_context' can get called before or while that context is used, and that needs to have a well defined semantic in the (lang independent) spec.
Having it a user level error is an option. Well, not really an error, but what you say (I think) is that the later operations on that object cannot use the Globus context - right?
Right, we agree. If there are more/other contexts that might still be OK. IMHO, if the programmer is removing a context that is still needed, that is a mistake that might lead to an error.
The problem is not really C++ here I think. The code snippet below is semantically challenging in any language, and we need to define that semantic in the spec.
The implementation in C++ is another issue, and simple :-)
The "problem" was that your mail was intertwining both aspects. Sure, the can be a simple setup in the C++ bindings, once the SAGA semantics are clear... Cheers, Thilo -- Thilo Kielmann http://www.cs.vu.nl/~kielmann/
