OpenDDS 3.9

Release notes for Version 3.9 of OpenDDS

Version 3.9 of OpenDDS.

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

OpenDDS 3.8

Release notes for 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

OpenDDS 3.7

Release notes for 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:

• OCI no longer builds with vc71, vc8, and GCC 4.1.1. If you require support
  of these older platforms contact sales@ociweb.com.
• The project repository is now at https://github.com/objectcomputing/OpenDDS

OpenDDS 3.6

Release notes for 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.

OpenDDS 3.5.1

Release notes for 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.

OpenDDS 3.5

Release notes for 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.
