Release notes for Version 3.6 of OpenDDS


  • The discovery framework of OpenDDS has been refactored to be more
    asynchronous. This should make discovery faster and more reliable
    for both publishing and subscribing clients, regardless of the
    discovery mechanism used (RTPS or InfoRepo).
  • DataWriters now release locks more quickly than before. This allows the
    transport to be available to more threads when compared to 3.5.1.
  • Improved DDS specification compliance with regards to reliability,
    resource limits, and history qos settings. Specifically, reliable
    data writers may block for max_blocking_time and potentially return
    DDS::RETCODE_TIMEOUT in situations where they would have simply
    written the data in older version of OpenDDS. The new behavior
    is required by the DDS specification, see section
    of the version 1.4 specification for details. This change affects
    various operations of the data writer interface including the
    write and register operations.


  • The wireshark dissector now supports wireshark versions 1.8.x, 1.10.x,
    1.12.x, and 1.99.1.
  • The modeling framework now support Eclipse 4.4 (Luna) and GMF 3.1.x
  • Added a public_address option for the tcp transport. This option
    allows a tcp transport instance to listen on one address (local_address)
    while advertising another address (public_address) to discovery.
    This feature was used to allow a proxy process between the subscriber
    and publisher in the TcpReconnect test, but may also be useful in
    other deployment scenarios, especially using OpenDDS through a firewall.


  • There were a number of concurrency and thread utilization improvements.
    These changes fixed a number of threading issues as well as improving
    the efficiency of publication.
  • Fixed some issues with RTPS discovery.
  • Fixed a number of issues related to the reconnect functionality of
    the tcp transport.
  • Fixed some bugs in the OpenDDS IPv6 support.
  • Eliminate duplicate samples received during durable resend.
  • Fixed memory leak at shutdown time in modeling library.


  • Many updates to make test results more complete and deterministic.
  • Added a TcpReconnect test that exercised the ability of the tcp
    transport to seamlessly reconnect OpenDDS clients when the transport
    layer drops a connection.
  • Added a WriteDataContainer unit test to verify data writer memory
    management compliance with the DDS specification.
  • Added a PubScalability test that was used to test association and
    publications with large numbers of subscribers.
  • Added a packet reassembly unit test.
