OpenFusion TAO 2.1.1.x Changes & Enhancements

The following changes or enhancements have been made to the OpenFusion TAO 2.1.1.x distribution:

OpenFusion TAO 2.1.1.0

• API Changes or Enhancements
  • Enhanced the plugable transports such that the send_message() api now provides an optional TAO_ServerRequest object pointer to provide access to any client side policies that are broadcast with each request. This enabled the ZIOP compression correction to be coded.
• Other Changes or Enhancements
  • Enhanced the MIOP protocol to allow for MIOP Packet fragmentation. Messages of an arbitary size can now be attempted via the MIOP protocol. It should be noted, however, that since MIOP is based upon connectionless UDP messages, the MIOP configuration needs careful set up, as there is no guarrentee that any particular message will actually arrive. (Larger messages are more likely to be lost than smaller ones, even if fragmented, without either side being aware that this has happened).
  • Enhanced the RW -ORBWaitStrategy and the EXCLUSIVE -ORBTransportMuxStrategy to also work with AMI requests.
  • Added Time_Policy_Manager, a TIME_POLICY strategy manager configurable through the service configurator framework. This allows the dynamic configuration of the TIME_POLICY strategy used for ORB timers and countdowns. TAO includes two default TIME_POLICY strategies as statically linked service objects; TAO_System_Time_Policy_Strategy and TAO_HR_Time_Policy_Strategy (the first being used as default strategy). The docs/Options.html file describes the configuration options in detail. Two new tests have been added exemplifying these new options; tests/Time_Policy and tests/Time_Policy_Custom. Furthermore two new compile time option macros have been added related to TIME_POLICY strategies: TAO_USE_HR_TIME_POLICY_STRATEGY if defined will force the use of the new TAO_HR_Time_Policy_Strategy as default time strategy instead of TAO_System_Time_Policy_Strategy; TAO_HAS_TIME_POLICY if explicitly defined as 0 ('#define TAO_HAS_TIME_POLICY 0') will build TAO without the new TIME_POLICY strategy support.
  • mt_noupcall has been improved and generically speaking the handling of client leader threads in LF has been improved and potential deadlock situations fixed.
  • The TAO IDL compiler now gives the following warning when anonymous types are used: 'anonymous types are deprecated by OMG spec'. This default action can be changed to either produce an error or not to issue any diagnostic message. One of the following defines can be added to the distribution's config.h file in order to change the behavior of the TAO IDL compiler: IDL_ANON_ERROR: The TAO IDL generates an error when it encounters an anonymous type. IDL_ANON_WARNING: The TAO IDL generates a warning when it encounters an anonymous type (the default behavior). ANON_TYPE_SILENT: The TAO IDL doesn't generate a warning nor an error when it encounters an anonymous type.
  • All of the TAO ORB services executables have been renamed so as to differenciate them between the ORB services of other CORBA vendors. * 'LifeCycle_Service' to 'tao_coslifecycle' * 'Dump_Schedule' to 'tao_dump_schedule' * 'NT_Notify_Service' to 'tao_nt_cosnotification' * 'Notify_Service' to 'tao_cosnotification' * 'FT_ReplicationManager' to 'tao_ft_replicationmanager' * 'IFR_Service' to 'tao_ifr_service' * 'TAO_Service' to 'tao_service' * 'Fault_Detector' to 'tao_fault_detector' * 'Scheduling_Service' to 'tao_cosscheduling' * 'Basic_Logging_Service' to 'tao_tls_basic' * 'Notify_Logging_Service' to 'tao_tls_notify' * 'Event_Logging_Service' to 'tao_tls_event' * 'RTEvent_Logging_Service' to 'tao_tls_rtevent' * 'Naming_Service' to 'tao_cosnaming' * 'NT_Naming_Service' to 'tao_nt_cosnaming' * 'CosEvent_Service' to 'tao_cosevent' * 'Event_Service' to 'tao_rtevent' * 'LoadManager' to 'tao_loadmanager' * 'LoadMonitor' to 'tao_loadmonitor' * 'Trading_Service' to 'tao_costrading' * 'Time_Service_Server' to 'tao_costime_server' * 'Time_Service_Clerk' to 'tao_costime_clerk' * 'ImplRepo_Service' to 'tao_imr_locator' * 'ImR_Activator' to 'tao_imr_activator' * 'Fault_Notifier' to 'tao_fault_notifier' * 'Concurrency_Service' to 'tao_cosconcurrency'
  • Improved the speed of tao_idl when processing large input files with many module re-openings.
  • Added IDL3+ support to TAO_IDL. Note that the keywords porttype/port/mirrorport are now fully implemented and reserved by tao_idl.
  • Added a capability to throw BAD_PARAM exception in case there is an attempt to access sequence elements above sequence length. By default this capability is turned on in debug builds with defining TAO_CHECKED_SEQUENCE_INDEXING. BAD_PARAM exception is also thrown in case a new sequence length for bounded sequence is greater than the bound defined in IDL.
  • Extended the TAO IDL compiler to take over all code generation from the CIAO CIDL compiler, which has been eliminated. See $TAO_ROOT/docs/compiler.html for details.
  • Updated ZIOP to match the OMG specification.
