[RFC] #2 - variable renaming in make_ref() of associations
Suggestion to rename some of the variables in make_ref()
to make the relations clearer.
Also moved the content of make_ref() to make_reference()
in libxkutil to generalize it. This make_reference can
then be used by each association's make_ref().

I like this. The rename is definitely more worthwhile if we generalize
it, and I agree that it really can be generalized, as this patch shows.
My only question is: would this be better suited to being part of
std_association instead of libxkutil? Seems like anything that will use
std_association will probably want to use make_reference().

No, the make_ref behavior is something we need to do in a special way
that others won't. Putting the (Xen_|KVM_) switch into
std_association would pollute libcmpiutil with libvirt-cim behavior.

Yes, that was my first try, until I had to realize that
get_typed_instance() is that special to our providers as Dan describes
below ;). So I had to move it to libxkutil.

Sounds good to me.

Why not just pass the make_reference function from libxkutil directly
in the std_assoc block? The function should be able to infer the name
of the reference from the assoc_class field of the std_assoc or info
struct, right?
That would let us cut out even more code from all the providers :)

That's a ery
interesting idea ! Sadly the current input parameter list
of make_ref_t() in struct std_assoc does not include a broker pointer,
which prevents me from reworking it in your suggested way. Maybe you
have an idea how to solve this ? Thanks :).

Ah, right :(
HE> Maybe you have an idea how to solve this ?
Perhaps we could have a macro that dispatches the make_reference()
function with the appropriate broker? Maybe something like the
following:
#define LIBVIRT_CIM_DEFAULT_MAKEREF \
static CMPIInstance make_ref(const CMPIObjectPath *ref, \
const CMPIInstance *inst, \
struct std_assoc_info *info, \
struct std_assoc *assoc) \
{ \
return default_make_ref(_BROKER, ref, inst, info, assoc);\
}
What do you think?

I think this is a neat idea.
