Additions

• IDL Maps are now supported by opendds_idl. (PR #4999)
  • We would like to thank tmayoff for contributing much of the work needed for this.
  • Usage example:

    @nested
    struct Item {
      string desc_name;
      uint32 count;
    };
    
    @topic
    struct Inventory {
      map<string, Item> items;
    };
    

  • They map to C++ std::map in both the classic IDL-to-C++ and IDL-to-C++11 mappings.
  • See IDL Compliance for known limitations.
• RtpsRelay
  • Output from RtpsRelay -LogRelayStatistics / RtpsRelay -PublishRelayStatistics includes extended RtpsRelay statistics (PR #4972, PR #5006)
  • Output from RtpsRelay -LogRelayStatistics / RtpsRelay -PublishRelayStatistics includes internal OpenDDS statistics (PR #5000, PR #5006, PR #4990, PR #5023)
  • RtpsRelay no longer needs to store and replay SPDP messages (PR #5017, PR #5020)
  • The OpenDDSInternalThread built-in topic has additional detail fields which may be populated by internal threads. (PR #5026)
    • The RtpsRelay's event handling threads make use of this feature.
  • RtpsRelay expiration/deactivation is now done by separate timer events instead of during input handling (PR #5032)
  • RtpsRelay -DrainInterval can drain clients to implement a controlled shutdown (PR #5063)
• Added [rtps_discovery] IgnoredSpdpUserTags. (PR #5046)
• When DDS Security is configured to require authentication and an incoming SPDP message has a different Identity CA, authentication is not attempted. (PR #5046)

Platform Support and Dependencies

• ACE/TAO
  • Updated ACE 6/TAO 2 from 6.5.21 to 6.5.22.
  • Updated ACE 8/TAO 4 from 8.0.3 to 8.0.4.
• CMake
  • opendds_target_sources now has a FOLDER argument which sets the CMake FOLDER property on generated targets. (PR #5009)
  • Fixed accidental use of RapidJSON's CMakeLists.txt file when building OpenDDS with CMake. (PR #5054)
    This caused issues such as forcing the CMAKE_CXX_STANDARD to C++11 and breaking the ACE C++ standard detection code.
  • Fixed configure issue with Xerces from vcpkg when building OpenDDS with CMake. (PR #5054)
• The configure script detects the C++ standard supported by the Android NDK compiler (PR #5057, PR #5052)

Fixes

• Reset heartbeat fallback when the sequence number advances. (PR #5048)
