CORBA24 — Nesting depth in valuetype end tags

  • Key: CORBA24-159
  • Legacy Issue Number: 3526
  • Status: closed  
  • Source: hursley.ibm.com ( Simon Nash)
  • Summary:

    Section 15.3.4.5 contains an inconsistency in the description of how end tags
    for valuetypes are written. Consider the case where an unchunked value (V)
    contains a chunked value (CV1). Should the end tag for CV1 contain a nesting
    depth of -2 or -1?

    The following sentence in the spec seems to imply that the correct value is -2:

    > The end tag is a negative long whose value is the negation of the absolute
    > nesting depth of the value type ending at this point in the CDR stream.

    However the spec also says:

    > The outermost value type will always be terminated by an end tag with a
    > value of -1.

    which is not true if the end tag for CV1 is written as -2, since no end tag
    with a -1 value will be written.

    Proposed resolution:

    Delete the second above sentence from the spec.
