DDSXTY12 — Builtin topics not backward compatible

Open Closed All
  • Key: DDSXTY12-33
  • Legacy Issue Number: 18310
  • Status: closed  
  • Source: ZettaScale Technology ( Mr. Erik Hendriks)
  • Summary:

    Builtin topics are not backward compatible with the DDS1.2 spec (not even according to the rules of the Extensible types spec itself).

    As an example, the BuiltinTopicKey_t array has been extended from 3 elements to 4 elements. This breaks compatibility with respect to non-xTypes compliant versions of a DDS product, and it is not cleared up why the keyfield suddenly required this extra element.
