Release notes for Version 1.3 of OpenDDS

  • This will be the final release of OpenDDS that will build with the current
    patch level of TAO 1.4a. This release is compatible with (the current patch
    levels of) TAO 1.4a, 1.5a, and 1.6a, as well as the current DOC Group
    beta/micro release. Future releases will be compatible with TAO 1.5a, 1.6a
    and the DOC group -- see the README file for details on TAO versions.

New to this version are the following changes:

  • Implemented the Communication Status entity structures and behaviors to
    conform with the version 1.2 specification (formal/07-01-01). This
    includes member name changes and additions to LivelinessChangedStatus;
    modifying and extending the SampleRejectedStatusKind enumeration; and,
    adding new members to the PublicationMatchStatus and
    SubscriptionMatchStatus structures.
  • Implemented the TRANSPORT_PRIORITY Quality of service policy using the
    policy value to set thread priorities and DiffServ codepoint values.
    The current implementation does not honor the Changeable behavior of
    the policy. Only the intially established policy value is honored for
    any given DataWriter Entity. Thread priorities are not currently set
    on Windows systems.
  • Implemented the LATENCY_BUDGET Quality of service policy as a
    monitoring feature with an extended listener callback for exceeded
    budget values. Statistics for latency are made available via an
    OpenDDS-specific extended API as well.
  • Implemented the ReadCondition interface and associated operations
    on the DataReader (such as read_w_condition).
  • Implemented the QueryCondition interface, but only queries of the form
    "ORDER BY a[, b, c...]" have any effect. In other words, it's a mechanism
    that controls the order of the data-set received from any given read or
    take operation. The ORDER BY fields can be either primitive types
    (including strings) or primitive types in nested structs (using a.b).
  • Corrected a bug in the LIFESPAN QoS implementation where the Topic QoS
    was used. Now the DataWriter QoS takes effect.
  • The PARTITION QoS policy now accepts character class wildcards using [].
  • Corrected a bug in the PARTITION QoS implementation where the default
    QoS would not match against the '*' wildcard.
  • The DURABILITY QoS implementation was corrected so that readers requesting
    the VOLATLIE kind will not receive historic samples from writers. Since
    there were some use-cases for the old behavior, it is available through an
    OpenDDS-specific interface -- see $DDS_ROOT/dds/DdsDcpsSubscriptionExt.idl.
  • When the writer's DURABILITY QoS is PERSISTENT, the format of the
    data stored on the filesystem has changed. Instead of a single file in the
    current working directory, a directory is now used. This is configurable
    using the option -DCPSPersistentDataDir.
  • A Java Message Service 1.1 (JMS) provider built on top of OpenDDS is now
    available in $DDS_ROOT/java/jms. JMS Topics are supported (not queuing).
    See the README in that directory for more info.
  • The $DDS_ROOT/bin/federation utility has been renamed to opendds_repo_ctl
    and now supports shutting down a remote non-federated DCPSInfoRepo process.
  • Deleting a DataWriter from a Publisher now blocks until pending samples have
    been delivered by the underlying transport. By default, the DataWriter will
    block indefinitely. To change the default blocking behavior, you may
    specify a number of seconds to block with the -DCPSPendingTimeout option.
  • Instance handles are now compliant with version 1.2 of the DDS
    specification. Additionally, the contains_entity and get_instance_handle
    operations have been implemented.
  • Implemented DataWriter::wait_for_acknowledgments() from formal/07-01-01.
  • Added support for Windows Mobile 6 (WinCE) Standard SDK, and ACE_USES_WCHAR
    builds in general. See docs/design/wchar.txt.
