Release notes for Version 2.0 of OpenDDS

  • This is the first release of OpenDDS that conforms to the minimum
    compliance profile as documented in formal/07-01-01 (version 1.2).
    Near-complete support for the persistence profile and initial support
    for the content-subscription profile is also provided in this release.

New to this version are the following changes:

  • Updated support for DataWriter::unregister() and DataWriter::dispose()
    to properly release resources after all samples in a marked instance
    are removed.
  • Implemented Publisher::wait_for_acknowledgments() as defined in
    formal/07-01-01.
  • Fixed an issue in QueryCondition where applying filters on non-valid
    data samples caused a SEGV; these samples are now implicitly filtered
    out.
  • Implemented PRESENTATION QoS policy as defined in formal/07-01-01.
    Currently, GROUP access is not supported.
  • Implemented MANUAL_BY_TOPIC and MANUAL_BY_PARTICIPANT LIVELINESS QoS
    policy kinds.
  • Implemented BY_SOURCE_TIMESTAMP DESTINATION_ORDER QoS policy kind.
    Samples may now be ordered based on reception or source times on a per
    instance basis.
  • Implemented ENTITY_FACTORY auto_enable support in formal/07-01-01.
    Entities may now be enabled manually by setting this value to false.
  • Implemented WRITER_DATA_LIFECYCLE as defined in formal/07-01-01.
    Instances will now be properly unregistered/disposed when a DataWriter
    is deleted.
  • Implemented READER_DATA_LIFECYCLE as defined in formal/07-01-01.
  • Implemented TIME_BASED_FILTER as defined in formal/07-01-01.
  • create_*() functions now take a StatusMask argument. A new constant
    named OpenDDS::DCPS::DEFAULT_STATUS_MASK has been introduced as a
    convenience to indicate interest in all status changes.
  • Implemented the following new methods on DomainParticipant as defined
    in formal/07-01-01:
    • get_discovered_participants()
    • get_discovered_participant_data()
    • get_discovered_topics()
    • get_discovered_topic_data()
  • Constant name changes:
    • PUBLICATION_MATCH_STATUS => PUBLICATION_MATCHED_STATUS
    • DURATION_INFINITY_SEC => DURATION_INFINITE_SEC
    • DURATION_INFINITY_NSEC => DURATION_INFINITE_NSEC
    • TIMESTAMP_INVALID_SEC => TIME_INVALID_SEC
    • TIMESTAMP_INVALID_NSEC => TIME_INVALID_NSEC
  • Removed constants:
    • TRANSPORTPRIORITY_QOS_POLICY_NAME
  • Type name changes:
    • StatusKindMask => StatusMask
    • SubscriptionMatchStatus => SubscriptionMatchedStatus
    • PublicationMatchStatus => PublicationMatchedStatus
  • Removed types:
    • SampleStateSeq
    • ViewStateSeq
    • OctetSeq
  • Other type changes:
    • BuiltinTopicKey_t is now a struct containing an array rather
      than a bare array type. This allows passing a BuiltinTopicKey_t
      by reference.
    • Ownership is now indicated in DataReaderQos and DataWriterQos as
      well as PublicationBuiltinTopicData and SubscriptionBuiltinTopicData.
    • Removed sevice_cleanup_delay from DurabilityQosPolicy.
  • Method name changes:
    • register()/_cxx_register() => register_instance()
    • register_w_timestamp() => register_instance_w_timestamp()
    • unregister() => unregister_instance()
    • unregister_w_timestamp() => unregister_instance_w_timestamp()
    • on_subscription_match() => on_subscription_matched()
    • on_publication_match() => on_publication_matched()
  • Other method changes:
    • set_qos(), get_qos(), get_*_status() and assert_liveliness() now
      return error codes as specified in formal/07-01-01.
    • Subscriber::get_datareaders() reader parameter has changed from out
      to inout.
