CORBA25 — get_interface() underspecified

  • Key: CORBA25-35
  • Legacy Issue Number: 4335
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    the text for get_interface() says:

    An operation on the object reference, get_interface, returns an object
    in the Interface Repository, which provides type information that may
    be useful to a program. See the Interface Repository chapter for a
    definition of operations on the Interface Repository. The
    implementation of this operation may involve contacting the ORB
    that implements the target object.

    This does not say what should happen if I call _get_interface() and

    • the interface repository isn't running,
    • the interface repository is running and can be reached, but
      doesn't contain an entry for the object's interface.

    Looking at the INTF_REPOS exception, we have:

    An ORB raises this exception if it cannot reach the interface
    repository, or some other failure relating to the interface
    repository is detected.

    This would indicate that, if the repository isn't running, the client should
    get INTF_REPOS. However, we have no idea what should happen if the repository
    is in fine shape, but no entry exists for the interface.

    Since an unpopulated interface repository is very much the same thing as
    no interface repository at all, I would like to flag both scenarios as an

    Proposal: add the following sentence to the end of

    If the interface repository is not available, get_interface() raises
    INTF_REPOS with minor code 1. If the interface repository does not
    contain an entry for the object's (most derived) interface,
    get_interface() raises INTF_REPOS with minor code 2.

    Update the minor code table in 4.11.4 accordingly.
