CORBA24 — Use of Principal in GIOP Module erroneous

  • Summary:

    In spite of objections based on misunderstandings from certain quarters
    I would like to propose that Principal in the IDL describing GIOP as
    excerpted below be replaced by "sequence <octet>". For whatever it might
    be worth, doing so would make the IDL in the GIOP module actually
    compilable for the first time in its entire existence!

    module GIOP { // IDL extended for version 1.1 and 1.2
    // GIOP 1.0
    struct RequestHeader_1_0

    { // Renamed from RequestHeader IOP::ServiceContextList service_context; unsigned long request_id; boolean response_expected; sequence <octet> object_key; string operation; Principal requesting_principal; ^^^^^^^^^ }

    ;

    // GIOP 1.1
    struct RequestHeader_1_1

    { IOP::ServiceContextList service_context; unsigned long request_id; boolean response_expected; octet reserved[3]; // Added in GIOP 1.1 sequence <octet> object_key; string operation; Principal requesting_principal; ^^^^^^^^^ }

    ;

    ...
    };

    Firstly, ever since the GIOP standard was adopted, the use of Principal
    in that struct has been erroneous, since it is undefined in GIOP module,
    unless adorned with a CORBA:: prefix. Secondly, in effect all that it is
    trying to say
    is that the Principal is represented as a sequence<octet> in the header
    field
    requesting_principal, not a Principal pseudo-interface, which is
    undefined in that context anyway. Thirdly, even if you could find a
    definition for an unadorned Principal somewhere, what is the meaning of
    that type when CDR encoded? It really is
    nothing but sequence<octet>.

    I think this issue should go to the Interop RTF.
