Issues Descriptions

Python: Alternate Mappings

  • Key: PYTH11-14
  • Legacy Issue Number: 3714
  • Status: closed  
  • Source: David Frankel Consulting ( David Frankel)
  • Summary:

    On page I-2 of ptc/00-04-08, the mentioning of alternate mappings
    is a serious issue, since it means that scripts may not be portable
    across implementations of this specification.

Python mapping: skeleton class name

  • Key: PYTH11-4
  • Legacy Issue Number: 3610
  • Status: closed  
  • Source: AT&T ( Duncan Grisby)
  • Summary:

    In document ptc/00-04-07, my issue, number 3237, is resolved in a
    rather bizarre manner. The specification as it now stands states that
    to name skeleton classes:

    'For the POA, the first element of the fully-scoped name of the
    interface is suffixed with "__POA".'

    The section no longer contradicts itself, but I object to the
    resolution to call the class M__POA, rather than POA_M. Here is a
    summary of how other language mappings name their skeleton classes
    for an interface I in module M:

    Ada: M.I.Impl
    C: POA_M_I
    C++: POA_M::I
    COBOL: POA-M-I
    Java: M.IPOA
    Smalltalk: seems not to have a skeleton mapping at all

Issue: Python language binding January 2000 Draft

  • Key: PYTH11-13
  • Legacy Issue Number: 3724
  • Status: closed  
  • Source: Boeing ( Jim Fulton)
  • Summary:

    The Python language binding says that IDL attributes are mapped
    to Python accessor functions with leading '_'s in their names:

    "If an interface defines an attribute name, the attribute is mapped into an
    operation _get_name, as defined If the attribute is not readonly, there is an
    additional operation _set_name, as defined in chapter 3.11 of CORBA 2.2."

    Traditionally, Python attributes and methods with leading '_'s in their
    names are considered to be private. The language enforces this in some cases.
    For example, names with leading '_'s are not automatically exported from
    modules and names used in class definitions are mangled to prevent
    external access if they begin with double '_'s and don't end in double
    '_'s.

    I feel strongly that the language mapping should be
    changed to get accessor method names without leading underscore,
    as in get_name(), or even just name(), as in the C++ mapping.

    On page I-9 of ptc/00-04-08: Are the declarations (not the
    implementations) of CORBA.Any, CORBA.ValueBase etc. just built into
    the environment, or are they explicitly declared somewhere?

Python: Servant base class

  • Source: David Frankel Consulting ( David Frankel)
  • Summary:

    On p. I-13 of ptc/00-04-08, it says the base class of all servant
    classes is PortableServer.Servant. I'm missing somewhat here: I
    thought the base class is M__POA.
