  • Fixed a few reference counting issues in internal classes

Notes:

  • This is the final version we will test with TAO 2.0a, please upgrade to a newer TAO (see README.md)

Version 3.9 of OpenDDS

  • Updated how DataWriter QoS is interpreted by internal data structures:

    • RESOURCE_LIMITS.max_samples_per_instance controls total samples that can be stored per instance, independent of HISTORY
    • HISTORY.depth controls number of samples (per instance) that will be made available to late-joining readers if DURABILITY is enabled
      • KEEP_ALL history uses max_samples_per_instance as its depth
    • WriteDataContainer is more eager to remove samples that are no longer needed
    • WriteDataContainer will not remove samples that are required to implement DURABILITY, hence if RELIABILITY is enabled this can block a write() just like other "no resource available" scenarios

  • Fixed an RTPS interoperability issue with the new ParticipantMessageData messages (used for liveliness)

  • Enhanced RTPS support for DURABILITY QoS enabling faster reader/writer associations when DURABILITY is in use (set to TRANSIENT_LOCAL)

  • RTPS Discovery has a new option "SpdpLocalAddress" which can be used to bind SPDP's socket to a particular network interface

  • InfoRepo discovery will use TAO's BiDir GIOP feature to reduce number of sockets needed (disable with -DCPSBidirGIOP 0)

  • Intermediate Type Language (itl), a helper library used by the OpenDDS wireshark dissector, is now included in the source tree in tools/IntermediateTypeLang. itl depends on the 3rd-pary lib rapidjson. When running the configure script, use --rapidjson=

  • Corrected makefile generation for Java bindings with IDL bounded strings

  • Fixed a bug where some header files would be missing from "make install"

  • "make install" now works with Java bindings

  • Configure script: now supports FreeBSD, Mac OS X El Capitan, and cross-compiles for Linux targets (Raspberry Pi and Intel Edison tested). The configure script attempts to find the JDK if invoked with --java.

  • cross-compilation now works with Java bindings, including use of JRE compact1

Version 3.8 of OpenDDS

  • Improved support for Safety Profile

  • OpenDDS multicast transport (reliable mode) now guarantees in-order delivery

  • Added a "default address" configuration parameter that sets an overall default for binding to a specific network interface

  • Fixed bugs in transport framework, udp transport, InfoRepo discovery, static discovery, and the Liveliness and Durability QoS policies

Version 3.7 of OpenDDS

Additions:

  • Implements FACE Transport Services API v2.1, FACE safety base and FACE safety extended profiles (Future Airborne Capability Environment).
  • Implements DDS 1.4 and RTPS 2.2.
  • Support allocations from memory pool in safety profile builds. Introduced standard library containers and strings, as well as TAO sequences that allocate from this pool.
  • To support FACE TS, the IDL struct DDS::SampleInfo has a new field opendds_reserved_publication_seq as an extension to the DDS specification.
  • Updated opendds_idl for FACE support, moving some of the code-generation from tao_idl to opendds_idl when targeting FACE TS.
  • Support IDL fixed type inside of DCPS_DATA_TYPE (used with FACE TS).
  • Type-specific DataWriterImpl and DataReaderImpl are now templates. Code generation now introduces a typedef of these.
  • Content filtering now supports modulus (MOD) operator as an extension.
  • Added a static (configuration-based) discovery mechanism.
  • RTPS Discovery is now supported when OpenDDS is built without built-in topics.
  • RTPS Discovery has a new configuration parameter SedpLocalAddress which configures the rtps_udp transport used internally by discovery in the same way that local_address configures a user-created rtps_udp transport instance.
  • Support non-default liveliness QOS in rtps_udp transport.
  • Support wait_for_acknowledgements in rtps_udp transport.
  • Support command line option -DCPSRTISerialization when integrating with RTI DDS using RTPS, to account for a different serialization algorithm.
  • Configure script handles some cross-compile builds and safety profile.
  • Support for new Visual Studio compilers (vc11, vc12, and vc14).
  • Support for clang builds on Mac OS X.
  • Removed support for old GCC compilers (<= 3.3).
  • opendds_idl command-line option -Gitl is a replacement for -Gws. Wireshark dissector now reads ITL files, rather than .ini files.

Fixes:

  • Fixed many tests for minimum profile builds.
  • Enforced correct behavior of a reliable data writer when history QoS is set to KEEP_LAST with depth=1.
  • opendds_idl can now be specified in user_macros.GNU instead of always assuming it is in $DDS_ROOT/bin (for -type gnuace builds).
  • Fixed initial IPv6 support in windows builds.
  • Fixed disassociate handling of local entities on loopback interface.
  • Corrected wait_for_acknowedgements for non-reliable writers to return success immediately.
  • Allow disassociating readers to finish processing messages from active writer before removing.
  • Remove TcpDataLink from DataLinkSet when connect() fails. Previously, the datalink would remain and would be seen as a fully-connected datalink by new associations.
  • DCPSTransportDebugLevel 1 messages are now association-oriented.
  • Fixed durable resend out-of-order handling for rtps_udp transport.
  • Fixed handling of acknowledgements during shutdown of rtps_udp data link.
  • RTPS Discovery now ignores 'RTPX' messages seen during RTI integration.
  • Dissection of unions in wireshark dissector (requires ITL).
  • Corrected reference counting scheme for Recorder and Replayer objects: the reference-counted handle types changed from _rch to _var.

Notes:

Version 3.6 of OpenDDS

Notes:

  • 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 2.2.2.4.2.11 of the version 1.4 specification for details. This change affects various operations of the data writer interface including the write and register operations.

Additions:

  • 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.

Fixes:

  • 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.

Tests:

  • 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.

Version 3.5.1 of OpenDDS

Notes:

  • Due to addition control messages in the 3.5.1 release, mixing 3.5.0 and 3.5.1 releases should work properly, but the 3.5.0 data readers can emit the following error message when associating with a durable 3.5.1 data writer: ERROR: DataReaderImpl::data_received unexpected message_id = 11 Upgrade all endpoints to 3.5.1 to remove this error message.

Additions:

  • Support later (>= 4.7) versions of GCC compilers, and later (>= 2.0a) builds of TAO. Configure script now downloads 2.2a by default.

  • Added IDL compiler support for typedef of string fields within unions. Added Java IDL compiler support for struct forward declarations.

  • Updated UML design diagrams to reflect current code base.

Fixes:

  • DCPSInfoRepo no longer informs a subscriber about a crashed or killed publisher. This made associations of current publishers and subscribers delayed until timeout was reached.

  • Fixed deadlock condition in send_delayed_notifications() resulting from multiple datawriters.

  • Fixed deadlock in DataLinkSet::send_control().

  • Fixed deadlock in WaitSet::wait() and DataReaderImpl::data_received().

  • Fixed multicast transport with multiple participants in a single process.

  • Fixed parsing of -ReassociateDelay argument by DCPSInfoRepo.

  • Fixed crash of long-lived zero-copy sequence when it is destroyed and crash of zero-copy sequence accessing released instances.

  • Fixed unprotected access to DataWriterImpl::reader_info_, and TransportSendStrategy::pkt_chain_.

  • Fixed multiple RTPS crashes when participant is being deleted.

  • Fixed RTPS crash when a data reader is being deleted.

  • Fixed problem for non-unique repo ids for multicast when multiple (non-federated) DCPSInfoRepos are used on the same network.

  • Fixed crash caused by back-pressure in transport causing the most recent sample for an instance to be dropped.

  • Fixed error in reconstruction logic for fragmentation of udp and multicast transport packets.

  • Fixed PublisherImpl and SubscriberImpl to properly set a DataWriterImpl or DataReaderImpl entity's deleted flag during deletion to allow association checks to properly identify entities that are being deleted and not proceed in association.

  • Fixed problem for persisted DCPSInfoRepo where persisted participants were never dissociating.

  • Fixed activity improperly occuring when a partipant is being deleted that caused pure virtual function calls. In one case, waiting now takes place during deletion of a data writer until all control messages sent during unregistration of instances are account for. In another case fixed so TransportSendControlElement will delete itself before it reports to the listener that the message has been delivered/dropped.

Tests:

  • Many updates to make test results more deterministic.

  • Added Reliability test.

  • Added ManyToMany test to test associations with additional participants, publishers, subcribers, data readers and data writers.

  • Added PersistentInfoRepo test.

  • Restored thrasher medium and high test cases.

  • Rewrite Priority test to make it verify proper QOS functionality.

  • Rewrite LargeSample test to make it verify message contents are as expected.

Version 3.5 of OpenDDS

  • Updates to RTPS support resulting from both interoperability testing (March 2013 OMG meeting) and user feedback.

  • Fixed a bug in the DataReader relating to the Deadline timer.

  • Generated TypeSupportImpl classes now contain nested typedefs that facilitate programming with C++ templates. See tests/DCPS/ManyTopicTest for an example of usage.

  • Added config options to bind RTPS-related multicast sockets to specific network interfaces. See the ChangeLog for details.

  • Fixed an opendds_idl code generated bug when typedefs of basic types are used as fields of structs.

  • Corrected a number of other bugs related to discovery and scaling.

Version 3.4.1 of OpenDDS

  • Added a new option to opendds_idl, -Wb,v8, which generates type support for copying DCPS structs from C++ objects to JavaScript objects -- requires the V8 JavaScript engine. See https://npmjs.org/package/opendds for OpenDDS integration with Node.js.

  • Fixed a bug in serialization with misaligned reads. It only impacts certain platforms with strict alignment requirements such as SPARC/SunCC.

  • Clang 3.2 is now a supported compiler.

  • Fixed a bug in the rtps_udp transport, in certain cases an invalid Gap submessage was sent which can result in data samples not being received.

Version 3.4 of OpenDDS

  • Added new OpenDDS-specific APIs for sending and receiving untyped data, (does not require code generation from IDL data structures). See the Recorder and Replayer classes and the test in tests/DCPS/RecorderReplayer.

  • Implemented the ability to send fragmented data with the rtps_udp transport.

  • Fixed a bug in copy_from_topic_qos(): the Ownership policy is now copied.

  • The optimization of publisher-side content filtering now applies to durable data in addition to newly written data samples.

  • As with versions before 3.2, the DCPSInfoRepo object reference is allowed to fail to resolve. If it fails, the current operation can be re-tried at a later time when the DCPSInfoRepo server is available.

  • Added a new option for per-domain default transport configurations.

  • Corrected IDL string constants for QoS policy names which were wrong in the DDS spec (GROUPDATA and TRANSPORTPRIORITY ..._QOS_POLICY_NAME). These are not used anywhere in OpenDDS.

Version 3.3 of OpenDDS

  • If an instance of a transport can't be set up, an exception is thrown so that different configuration parameters can be attempted by the user.

  • Corrected the mapping of Priority QoS to DiffServ CodePoint DS subfield.

  • For thread-per-connection send, if no explicit scheduling policy has been configured, OpenDDS will now inherit the current thread's policy/priority.

  • Fixed a possible deadlock of RTPS discovery on Windows.

  • Added non-blocking I/O setting to tcp sockets, VxWorks 6.4 required it.

  • Fixed various bugs in deadline and ownership QoS.

  • Improved multicast transport's robustness during handshaking when many connections are set up at the same time, and also allow for multicast to skip over received datagrams that don't have the expected header values.

  • Multicast transport configuration can now specify a local network interface which will be used to join the multicast group.

  • The support for the generation of the DDS4CCM needed LEM library has been moved to CIAO DDS4CCM. This removed the optional dependency on CIAO.

Version 3.2 of OpenDDS

  • Added a new transport type: Shared Memory Use shmem as the short name (in place of "tcp", "udp", "multicast", etc.). See dds/DCPS/transport/shmem/ShmemInst.h for configurable parameters.

  • The udp transport now supports setting IP DSCP (DiffServ CodePoint) based on the writer's TRANSPORT_PRIORITY QoS value.

  • Fixed bugs in udp and multicast transports, including reassembly of fragments.

  • Made several changes in order to support CIAO 1.1.2 with DDS4CCM. From this version DDS4CCM has support for OpenDDS as DDS vendor. Check the CIAO release notes for details on what has been ported.

  • Added new QOS_XML library with which QoS settings can be done through an XML file. Used at this moment by the CIAO DDS4CCM implementation.

  • Implemented rejection of samples due to exceeding max_instances and max_samples.

  • Made the RTPS discovery and transport code more robust.

  • Refactored InfoRepo-based discovery into its own library. This reduces the dependency on TAO such that certain TAO libraries will no longer be loaded unless they are needed for InfoRepo-based discovery.

  • For IDL files that only contain local interfaces, the generation of server-side TAO code was suppressed. The suppression applies to DdsDcps*.idl. This means, for example, that code that was including DdsDcpsSubscriptionS.h needs to be changed to include DdsDcpsSubscriptionC.h.

  • To reduce library size, OpenDDS can now be conditionally compiled to exclude profiles discussed in the Compliance section of the DDS spec. See section 1.3.3 in the Developer's Guide for more information.

Version 3.1 of OpenDDS

  • This release includes the initial implementation of DDS Interoperability in OpenDDS, using the DDS-RTPS spec v2.1 from the OMG (formal/2010-11-01).

    RTPS support in OpenDDS consists of two main features:

    • A pluggable transport implementation, known as "rtps_udp" because it implements the UDP PSM of the DDS-RTPS spec. This is a peer of the existing OpenDDS-native transports: "tcp", "udp", and "multicast".

    • A new discovery mechanism for RTPS's distributed discovery. This can replace the DCPSInfoRepo in existing OpenDDS deployments.

    Neither of these features is enabled by default. See the OpenDDS Developer's Guide chapter 7 for configuration details. Also, note that not every OpenDDS feature (for example, certain QoS values) is supported with RTPS in the initial implementation. These exceptions are documented in the Developer's Guide sections 7.3.3 and 7.4.5.5.

  • Changed set_qos() of DataWriter, DataReader, Publisher and Subscriber so when provided a QoS value incompatible with an existing association, that the value will be changed, association will be broken, and RETCODE_OK returned. Previously, if any association would be broken, no change would take place and false would be returned. New version is compatible with DDS spec.

  • OpenDDS udp transport enhancements:

    • Added send_buffer_size and rcv_buffer_size parameters to the udp transport configuration.
    • The default local address will use DNS host names instead of IP addresses.
    • Added support for IPv6 when ACE is built with IPv6 support.

  • OpenDDS multicast transport enhancements:

    • Added a configuration parameter "async_send" (defaults to false) that will send multicast datagrams using async I/O if supported by the platform. As of now this is only implemented on Windows. It could be extended to Unix aio_*() functions in theory, but these are generally not preferred and the regular socket functions are sufficiently fast.

  • Removed DataReaderQosExt from DdsDcpsSubscriptionExt.idl. This was only being used to provide a non-standard-compliant backwards-compatibility setting to get the DURABILITY QoS behavior matching that of OpenDDS v1.2 and earlier. It was not being used in any OpenDDS code.

Version 3.0.1 of OpenDDS

  • The DCPSInfoRepo reassociates Built in Topic connections for existing datareaders and datawriters when restarted from persistence.

  • The opendds_idl compiler will now print a warning about not including TAO's orb.idl file when a file named orb.idl is included.

  • Fixed a bug where the timeout for passive_connect_duration was ignored.

  • Fixed multiple bugs in fragmentation/reassembly used for udp and multicast.

  • Fixed multicast loopback and session re-use problems.

  • Fixed a bug with memory management for the TransportCustomizedElement used in publisher-side content filtering.

  • New example Messenger.minimal - which is like messenger, but streamlined for new users to understand the whole easier.

Version 3.0 of OpenDDS

  • Transport configuration has undergone a major redesign and any existing transport application code or transport configuration files need to be updated. See the Developer's Guide for details of the design. See $DDS_ROOT/docs/OpenDDS_3.0_Transition.txt for a description on how to migrate your applications to the OpenDDS 3.0 design. As a part of this design OpenDDS gains the following capabilities:

    • Most applications can do all transport configuration via configuration files (no transport source code required).
    • Individual writers and readers can now support multiple transports.

  • The simpleTcp transport was renamed to tcp (the directory containing its source code was also renamed).

  • The udp transport no longer required a local_address when being configured. If not specified, the property defaults to a value selected by the operating system (similar to the tcp transport).

  • Details of the OpenDDS Modeling SDK changes in this release are documented in the Eclipse-based help, see OpenDDS Modeling SDK Guide -> Getting Started -> Introduction to the OpenDDS Modeling SDK.

  • First release of OpenDDS Real-Time Data (RTD) for Excel an Excel Add-in and RTD Server. It allows visualization of an operating OpenDDS system from within Excel. It gives a tree view of a repository that mirrors the stand-alone OpenDDS Monitor application's tree view, but with the additional capabilities to automatically restart monitoring of a repository when a saved workbook is opened, monitoring multiple repositories simultaneously, and snapshot a repository monitor tree view.

  • Wireshark dissector improvements include removal of the restriction that inforepo IOR be placed in a special file. Dissector config files can now be generated by opendds_idl.

  • The monitor tool has a new view which is an alternate to the Graphviz view. The Node view uses Qt gui elements to model the OpenDDS system. Users can manipulate Node view graphs before saving them to PNG files.
