USER VISIBLE CHANGES BETWEEN CIAO-1.1.9 and CIAO-1.2.0 ======================================================= USER VISIBLE CHANGES BETWEEN CIAO-1.1.8 and CIAO-1.1.9 ======================================================= . Improved support of DDS4CCM with OpenDDS as underlying DDS implementation USER VISIBLE CHANGES BETWEEN CIAO-1.1.7 and CIAO-1.1.8 ======================================================= . Added type_name attribute to DDS4CCM TopicBase connector . Fixed a few code generation bugs USER VISIBLE CHANGES BETWEEN CIAO-1.1.6 and CIAO-1.1.7 ======================================================= . Added support for RTI DDS 5.0.0 rev00 USER VISIBLE CHANGES BETWEEN CIAO-1.1.5 and CIAO-1.1.6 ======================================================= . None USER VISIBLE CHANGES BETWEEN CIAO-1.1.4 and CIAO-1.1.5 ======================================================= . Added basic hello world example USER VISIBLE CHANGES BETWEEN CIAO-1.1.3 and CIAO-1.1.4 ======================================================= . The CIAO DDS4CCM integration with OpenDDS has been reworked in a way that OpenDDS doesn't know anything anymore from CIAO. In order to use DDS4CCM with OpenDDS you need OpenDDS 3.3 or higher. USER VISIBLE CHANGES BETWEEN CIAO-1.1.2 and CIAO-1.1.3 ======================================================= . DDS4CCM with OpenDDS 3.2 or higher now can use the QoS XML files. The DDS4CCM profile#library convention is handled as filename#profile. . Further extended and improved support for OpenDDS as DDS vendor. Several unit tests have been updated to wait for DDS status callbacks in order to start the test instead of starting on ccm_activate . Refactored domain participant re-use in DDS4CCM. Domain participant re-use was initially implemented for RTI DDS but now it's available for other DDS vendors as well. . Added support for so called service components which are available through the component context using resolve_service_reference. Service components are deployed as regular components, but are installed by the installation handler (see the TTSCTest test) or they install themselves into the service registry (see TTSConnContext). These components can be seen as container plugins which are going to be used for various extensions without causing the container to be huge and unmaintainable . Removed preliminary support for the extension container USER VISIBLE CHANGES BETWEEN CIAO-1.1.1 and CIAO-1.1.2 ======================================================= . Added support for DDS4CCM with OpenDDS 3.2 or higher as DDS implementation. At this moment basic integration has been completed, all tests/examples do compile and part of them do run. To be added are support for the QoS XML files and the sharing of domain participants between connectors when using OpenDDS. After these extensions have been implemented we will analyze and resolve the test failures USER VISIBLE CHANGES BETWEEN CIAO-1.1.0 and CIAO-1.1.1 ======================================================= . Fixed problem with component sequence attributes . Minor bug fixes . Generated starter executors with -Gex have much more doxygen documentation being generated USER VISIBLE CHANGES BETWEEN CIAO-1.0.8 and CIAO-1.1.0 ======================================================= . Added support for new ciao config property "edu.vanderbilt.dre.CIAO.OpenMode" which controls the mode that is used to load the shared libraries for a home or component. By default we use ACE_DEFAULT_SHLIB_MODE USER VISIBLE CHANGES BETWEEN CIAO-1.0.7 and CIAO-1.0.8 ======================================================= . None USER VISIBLE CHANGES BETWEEN CIAO-1.0.6 and CIAO-1.0.7 ======================================================= . -Glfa has been removed from tao_idl. The local executor mapping can only be generated for the current file. Also at the moment an interface is compiled with tao_idl, the option -Gsv has to be used to generate the needed CCM facet servant . CIAO now supports the synchronous port and the ami4ccm lem pragma as documented in the AMI4CCM Initial submission by Remedy IT (mars/11-06-01) . Homes are now functional for connectors USER VISIBLE CHANGES BETWEEN CIAO-1.0.5 and CIAO-1.0.6 ======================================================= . It is now possible to connect connections in a deployment plan at deployment time instead of connecting them on first use. This can be established by setting the CIAO_PRE_ESTABLISH_CONNECTIONS define in your config.h. . The DDS4CCM connector now only creates a DDS subscriber or DDS publisher when they are needed. Previously, the DDS4CCM always created a DDS publisher and DDS subscriber, regardless of need. . Besides late binding, it is now possible to reset the topic name in the DDS4CCM connector. This means that the DDS4CCM connector is able to switch between topics of the same data type at runtime. Resetting a topic name means that DDS will be closed down and started again, using the new topic name. On the outside, all connections to and from the connector stay intact; therefor the user doesn't need to re-establish the connections again. Please see $CIAO_ROOT/connectors/dds4ccm/tests/ResetTopic/README for more info. This directory also contains some examples on how to reset a topic name. Since this is not spec-compliant behavior, an issue has been be raised on the DDS4CCM specification. . Improved thread safety in the CIAO core. . Direct collocation between components is now supported. In order to enable this add ccm_direct_collocation=1 to your default.features. We do recommend to use the new -ORBCollocationStrategy best which does not require all user components to be compiled with direct collocation enabled. Enabling direct collocation does increase the size of the generated code . All facet servants are now generated in the new _svnt_T.{h,cpp} files. This is a first step in more refactoring in the CIAO servants. Together with the TAO skeleton refactoring the skeleton for the Null_Component example decreased from 40206 bytes to 24971 bytes, the generated servant from 56959 bytes to 54933 bytes. The skeleton for the related Null_Interface reduced from 9559 bytes to 4526 bytes. . Added support for DDS4CCM using RTI DDS 4.5e on RHEL 6.1 USER VISIBLE CHANGES BETWEEN CIAO-1.0.4 and CIAO-1.0.5 ======================================================= USER VISIBLE CHANGES BETWEEN CIAO-1.0.3 and CIAO-1.0.4 ======================================================= . The thread switch feature in DDS4CCM now requires that ACE_HAS_REACTOR_NOTIFICATION_QUEUE is enabled. USER VISIBLE CHANGES BETWEEN CIAO-1.0.2 and CIAO-1.0.3 ======================================================= . DDS4CCM now compiles with OpenDDS integration enabled. This will not run because several methods in the core of DDS4CCM are still commented out. . The display example has been upgraded to Qt4 and has been made functional again . The hello example has been updated to the latest implementation guidelines USER VISIBLE CHANGES BETWEEN CIAO-1.0.1 and CIAO-1.0.2 ======================================================= . Generate servant code for facets and receptacles is now thread safe, the code for consumers/publishers/emitters still have some thread safety issues and a possible deadlock . Improved disconnect of connections in general and extended our test suite for that . Restructured base projects for dds4ccm to make a clear distinction between plain ndds and our idl to cpp wrapper around it . Validated with ndds 4.5drev03 . Added serialize_key_with_dispose and propagate_dispose_of_unregistered_instances as BOOLEAN_TRUE to the DDS QoS xml file for several tests to always get the key of the sample in the on_deletion callback . The logging service now supports custom backends. These are enabled using CIAO_LOG_BACKEND. Please see the DAnCE NEWS file for more details. DDS4CCM also supports the custom backend service, initialized with DDS4CCM_LOG_BACKEND. USER VISIBLE CHANGES BETWEEN CIAO-1.0.0 and CIAO-1.0.1 ======================================================= . Improved disconnect of Simplex/Multiple facets and receptacles. . Improved disconnect of consumers and publishers. . Resolved some memory leaks in the DDS4CCM library. Therefor a lot of tests were rewritten, using the generated executor implementation. . Improved doxygen documentation. . Improved IDL to C++ wrapper for NDDS. Therefor one is able to create a NDDS only application without using the DDS4CCM connector itself. See $CIAO_ROOT/connectors/dds4ccm/examples/IDL2CPPWrapper for an example of such an application. . Improved the DDS4CCM connector so that the user is able to implement his/her own connector. See $CIAO_ROOT/connectors/dds4ccm/tests/MultipleTemp/Connector/MultipleTemp_Connector_T.cpp/h for an implementation of such a connector. . Improved the DDS4CCM connector so that it can handle more than one topic. See $CIAO_ROOT/connectors/dds4ccm/tests/MultiTopic/ for an implementation of such a connector. USER VISIBLE CHANGES BETWEEN CIAO-0.8.3 and CIAO-1.0.0 ======================================================= . Implemented 'LateBinding' in the DDS4CCM connector. This means that the DDS entities will NOT be created and initialized when the topic name is empty at deployment time (e.g. the topic_name is empty in the deployment plan). The DDS entities will be created and initialized once the topic name is set at run time. . Reworked dds4ccm core to make it easier to implement custom dds4ccm connectors. Any already written custom dds4ccm connectors will need to be updated because of changes in the C++ template signature and the internal classes. . Improved dds4ccm logging . AMI4CCM reply handler is now generated for any user component that uses AMI4CCM, not with the AMI4CCM connector anymore USER VISIBLE CHANGES BETWEEN CIAO-0.8.2 and CIAO-0.8.3 ======================================================= . Tests for the Component Implementation Framework have been added. Because of this, two methods ('get_named_receptacles' and 'get_connections') off the receptacle interface were implemented in the CCM core. . DAnCE has been made an entirely separate product from CIAO, and has been moved from ACE_wrappers/TAO/CIAO/DAnCE to ACE_wrappers/TAO/DAnCE. . A new option has been added to the TAO IDL compiler. This option extends the -Gex option. When applying -Gexr, the TAO IDL compiler will generate an extra method which retrieves the ACE_Reactor from the ORB. One should use this option when an ACE_reactor. In code, use 'this->reactor ()' to get the ACE_Reactor. A CORBA::INTERNAL exception is thrown when the ACE_Reactor cannot be retrieved. The goal of this method is to prevent memory leaks. . The DDS4CC connector now has its own logging level. This log level can only be set using an environment variable, called DDS4CCM_LOG_LEVEL. The following log levels are defined: - DDS4CCM_LOG_LEVEL_ERROR 1 - DDS4CCM_LOG_LEVEL_CAST_ERROR 2 - DDS4CCM_LOG_LEVEL_DDS_NIL_RETURN 3 - DDS4CCM_LOG_LEVEL_4 4 //unused - DDS4CCM_LOG_LEVEL_5 5 //unused - DDS4CCM_LOG_LEVEL_ACTION 6 - DDS4CCM_LOG_LEVEL_UNIMP_ACTION 7 - DDS4CCM_LOG_LEVEL_ACTION_STARTING 8 - DDS4CCM_LOG_LEVEL_CAST_SUCCESSFUL 9 - DDS4CCM_LOG_LEVEL_DDS_STATUS 10 . Started the implementation of the Qos4CCM specification. Therefor an Extension Container has been added to CIAO. For now its possible to register the various interceptors (Client, Server, Servant and Stub interceptors) with an Extension Container (see $CIAO_ROOT/tests/COPI/Registration/Client). At this moment, DAnCE is unable to deploy an Extension Container 'out of the box'. If the DANCE_DEPLOYS_EXTENSION_CONTAINER define in config.h is set, DAnCE will deploy only Extension Containers (and no Session Containers). In the future, DAnCE should be able to deploy Extension Containers via a Deployment plan. . Added nddsmonitor as MPC feature to enable linking with the rtimonitor library . Resolved several memory leaks in CIAO/DAnCE/DDS4CCM . The tao_idl option -Gex now also generates a member and implemented set/get methods for attributes defined in components . Added mpc feature ccm_noevent which disable the CORBA event support in the core libraries and generated code . Implemented disconnect for local facets USER VISIBLE CHANGES BETWEEN CIAO-0.8.1 and CIAO-0.8.2 ======================================================= . Separate lifecycle of the dds4ccm connector and its facets . Improved dds4ccm logging . Fixed several memory leaks in CIAO and DAnCE . Destructors for component executors prior to this release were never invoked. This bug has been fixed, and component executors are now properly destructed. . Installation handlers, deployment interceptors, and locality configurators are now loaded at run-time instead of statically configure at compile time. This is accomplished with the use of a locality configuration file passed on the command line. Please see CIAO/examples/Hello/descriptors/run_test_shs.pl and DAnCE/tests/CIAO/Executor-Destructors/Component.cdp for examples of how to pass this file to the locality manager. The default locality configuration is loaded from DAnCE/bin/ciao.localityconfig. Please see documentation located in DAnCE/docs/localityManager-Plugins.txt. . Names for operations in the deployment interceptors have changed slightly to remove the 'instance_' prefix on all operation names. Please see DAnCE/DAnCE/DAnCE_DeploymentInterceptors.idl. . Deployment interceptors have a new operation that is invoked when unexpected events occur. This is currently only invoked when the NodeApplication receives notification that a locality manager has exited unexpectedly. . A locality configurator that sets the process priority has been included. USER VISIBLE CHANGES BETWEEN CIAO-0.8.0 and CIAO-0.8.1 ======================================================= . Implemented _get_component for AMI4CCM . Implemented resetting of Query Conditions in the DDS4CCM connector. This according to the beta 3 specification. . Added a preliminary System Health and Status Service. Please see DAnCE/tools/System_Health. This has two parts: there is the interceptor, which publishes instance status updates using a strategizeable transport protocol (included in this release is a simple CORBA transport plugin), and there is the dance_shs_daemon. A test which uses the SHS service is CIAO/examples/Hello/descriptors/run_test_shs.pl. . Added a new configuration plugin facility to the LocalityManager. This faciliy will invoke configuration plugins based on configProperties attached to an explicitly deployed LocalityManager instance. Included plugins are one for CPU Affinity, and another for setting the locality manager process name. Both work only under Linux 2.6 and later. Please see DAnCE/tests/LocalityManager/ProcessName and DAnCE/tests/LocalityManager/CPUAffinity for information on how to use these plugins. . There is a known bug when running some of the LocalityManager tests (DAnCE/tests/LocalityManager), in which an attempt to tear down a locality manager with no installed components results in a memory access violation. This will be fixed in CIAO 0.8.2. USER VISIBLE CHANGES BETWEEN CIAO-0.7.9 and CIAO-0.8.0 ======================================================= . Generalized DDS4CCM connector support to allow user-defined DDS4CCM connectors . Added support for structs in the deployment plan . Updated DDS4CCM to the beta 3 specification which includes - explicit support for ContentFilterTopics - porttype may contain attributes - all sequence are now inout instead of out - DDS vendors can deliver their own partial template specialization to handle differences between vendors . Completed AMI4CCM support . Added tutorials for DDS4CCM and AMI4CCM . Updated Quoter tutorial for the latest CoSMIC release . The ACE_FOR_TAO MPC feature is not supported anymore for CIAO . The DeploymentInterceptor interfaces have been merged into a single interface. . All currently defined interception points are currently invoked at the locality level when deploying plans. . The NodeApplication and LocalitManager have been refactored to use a thread pool based dispatching system for executing deployment actions. This allows the NodeApplication to use multiple threads to spawn new dance_locality_manager processes. The LocalityManager will, for the time being, be restricted to using only the ORB thread for dispatching deployment events. . Most deployment errors are now passed to installed deployment interceptors. DAnCE will include interceptors for extant semantics (first failure) and initial support for best effort semantics, whereby deployment failures are logged by otherwise ignored. . An Artifact Installation framework has been added to DAnCE and integrated into the NodeApplication. The framework provides a plugin system for installation handlers and a pluggable local node installation repository/cache. Installation handlers are selected based on the 'scheme' identifiers of location URLs from installation artifact entities in the deployment plan. Multiple installation schemes can be nested inside a single location URL as ://://. The framework comes with 'file' and 'http' scheme installation handlers and a simple local filesystem based installation repository/cache. USER VISIBLE CHANGES BETWEEN CIAO-0.7.8 and CIAO-0.7.9 ======================================================= . CIAO's default makefiles (traditional ACE/GNU, not autoconf/automake) now support installation with "make install". Please see the ACE-INSTALL.html file for instructions. . CIAO now enabled the LwCCM profile by default. This reduces the size of the generated code and the core libraries significantly. If you need any of the full CCM features, set ccm_lw=0 in your default.features file. . Updated AMI4CCM naming and extended the test suite . DDS4CCM tests and examples now instantiate the CCM_DDS::Typed module which gives us the DDS_Event and DDS_State connectors directly without requiring the user to manually derive a connector from DDS_Event and/or DDS_State . The way attributes are set from the cdp file onto the components has changed, any mismatch between the attribute datatype in IDL and the CDP file will cause to a StartError . The interpretation of locality constraints in deployment plans has changed slightly. Previously, any components not explicitly included as part of a locality group would be installed into their own, seperate locality. Now they will be installed into an arbitrarily chosen locality on the same node. . The first version of the DAnCE LocalityManager entity has been added to the repository. As such, launching components with ciao_componentserver is no longer supported, and dance_locality_manager should be used instead as the component server argument to dance_node_manager. . The way explicitly homed components are represented in deployment plans has changed. The section needs to have an execParameter with name "edu.vanderbilt.dre.DAnCE.ImplementationType" and value "edu.vanderbilt.dre.CCM.HomedComponent". The section needs to have a configProperty with name "edu.vanderbilt.dre.CIAO.ComponentHomeId" and value is the field of the home that is managing that component. . The way component server processes are explicitly deployed and passed command line arguments has changed. The field must have an execParameter named "edu.vanderbilt.dre.DAnCE.ImplementationType" and value "edu.vanderbilt.dre.DAnCE.LocalityManager". To pass command line arguments, the instance must have a configProperty named "edu.vanderbilt.dre.DAnCE.LocalityArguments". . Connection of emits/publish/consume ports is no longer supported via externalReference endpoints. Simplex and multiplex facet/receptacle connections continue to be supported. . DDS4CCM is compliant to the beta 2 specification, the next micro release will be updated to match beta 3. USER VISIBLE CHANGES BETWEEN CIAO-0.7.7 and CIAO-0.7.8 ======================================================= . dance_plan_launcher has been extensively re-factored, resulting in several new features: 1) dance_plan_launcher may now deploy locality-constrained plans directly to a NodeManager. 2) dance_plan_launcher now has the ability to deploy CDR encoded deployment plans in a portable manner. 3) dance_plan_launcher's command line options have been cleaned up to be more intuitive. The major user-visible change is -q (for application teardown) has been renamed -s. 4) Most plan_launcher business logic is encapsulated in an implementation library that may be leveraved by users to write custom executor agents. . All DDS4CCM callbacks will be deliverd to the user component on the CCM thread, not on the DDS thread. This does mean a small performance penalty, if you don't want to get this threadswitch, define CIAO_DDS4CCM_CONTEXT_SWITCH to zero in your config.h file . DDS4CCM uses a ContentFilteredTopic to implement the QueryFilter. If you want to use DDS QueryCondition instead add DDS4CCM_USES_QUERY_CONDITION as 1 to your config.h file . The user sequences in our DDS4CCM examples and tests have been updated to use Seq as postfix instead of _Seq. The RTI DDS specific sequence is now named with the RTISeq postfix . DDS4CCM doesn't work anymore with RTI DDS 4.4d, you will need to use at least 4.5b version with an updated CCK . AMI4CCM has been partly implemented into TAO_IDL and the Hello example has been updated. The naming conventions and exact code generated will be reviewed after this micro release. . The DDS4CCM connectors do initialize themselves completely after creation, this does mean that one DDS_Event connector has always 1 writer and 2 readers, also when you just write samples and don't use read or listen. The latency performance test shows current an overhead of 10% to 13%, but this does include the additional readers. USER VISIBLE CHANGES BETWEEN CIAO-0.7.6 and CIAO-0.7.7 ======================================================= . Reworked MPC support for dds4ccm. If you want to use dds4ccm you need to obtain the source distribution and for NDDS add dds4ccm_ndds=1 to your default.features file and generate the project files . Implemented more dds wrapper calls in the dds4ccm library . All DDS4CCM connectors are now generated by tao_idl . Did major cleanup in DAnCE to reduce dependencies and code size . Fix bug with DAnCE logging that cause the dance_node_manager not to log any messages . Extended dds4ccm test suite . Fixed -Glfa support . Added a new tool, dance_split_plan, which will allow a user to split a deployment plan into locality-constrained CDR-encoded deployment plans. . Added a new tool, dance_convert_plan, which will allow a user to validate and optionally convert a XML encoded deployment plan into CDR. . CIAO and DAnCE logging are silent by default, no messages are printed anymore. If you want to enable logging use the environment variables CIAO_LOG_LEVEL, DANCE_LOG_LEVEL, CIAO_TRACE_ENABLE, DANCE_TRACE_ENABLE, DANCE_LOG_FILE, and CIAO_LOG_FILE. For the executables we have the commandline arguments -DAnCELogLevel, -DAnCETraceEnable, -DAnCELogFile, -CIAOLogLevel, -CIAOTraceEnable, and -CIAOLogFile USER VISIBLE CHANGES BETWEEN CIAO-0.7.5 and CIAO-0.7.6 ======================================================= . Added support for the environment variable DDS4CCM_NDDS_LOG_VERBOSITY. This controls the ndds verbosity which is default set to silent . Added support for the DDS State and Event connector with all ports. A set of tests has been added to test these connectors. We implement now the biggest part of the recent OMG 09-10-25 specification . Extended AMI4CCM prototype with the latest ideas. The TAO_IDL compiler has some hardcoded generation just for Hello example. It has to be extended to generate the AMI4CCM connector and after that we can remove the hardcoded generation with the real generation code . Added support for components/connectors with local interface. In the cdp a deployRequirement has to be specified for any local connector . Use the templated module support for dds4ccm . Added suppor for #pragma ciao lem to handle the issues with the include of the E.idl file USER VISIBLE CHANGES BETWEEN CIAO-0.7.4 and CIAO-0.7.5 ======================================================= . Added rudimentary support for PlanLocality, which allows DAnCE to spawn multiple CIAO processes per node. Currently, only SameProcess constraints are honored. SameProcess constraints are honored by creating a separate process per constraint as it appears in the plan, with the appropriate component instances spawned in each process. Constraints are not rigerously checked by the runtime, so behaviour when a component instance appears in multiple SameProcess constraints is currently undefined. Components not appearing in any constraint are placed in a default component server process. . DDS4CCM has been updated to match the beta 2 spec. If you want use a templated module, use TYPED_MODULE macro as helper until the TAO_IDL compiler supports templated modules . Updated all DDS4CCM code/examples/tests to match beta 2 . Added Shapes sender/receiver for DDS4CCM . The configProperty edu.vanderbilt.dre.CIAO.ComponentServer.Executable can be used in the deployment plan to set a different ciao component server executable . The configProperty edu.vanderbilt.dre.CIAO.ComponentServer.Args can be used in the deployment plan to specify a set of additional commandline arguments that are than passed to the ciao component server . Added support for the environment variable DDS4CCM_DEFAULT_DOMAIN_ID This influences the default domain id which is set by the connector. All test deployment plans don't set a domain id, which cause problems during testing because everyone is in the same domain. Each developer and build system on the same network should have its own unique id to get an isolated test environment. . DDS4CCM qos_profile attribute has to be used as library#profile. If this is not set, we use default qos . Removed DDS4CCM monolotic connector because it was not in the spec USER VISIBLE CHANGES BETWEEN CIAO-0.7.3 and CIAO-0.7.4 ======================================================= . Added second prototype of DDS4CCM that uses the RTI CORBA Compatibility kit and a monolitic connector . Extended AMI4CCM prototype . Update all examples and tests for the changes in the -Glem TAO_IDL option. The behavior of this option has changed dramatically, and will require that most user applications be ported. Previously, -Glem would cause the IDL compiler to generate a E.idl file containing local executor mapping for all interfaces provided as ports by any components in the main translation unit. Therefore, files with interfaces, but no components defined will have empty E.idl files generated. Similarly, a file with no interfaces defined, but with components defined would generate LEM interfaces for interfaces provided by that component but not local to the file in question. While this behavior simplified a rudimentary use case where interfaces would be provided by only one component, more complicated use cases were much more difficult to achieve. The new behvior causes the IDL compiler to generate LEM IDL for all interfaces within a given translation unit, regardless of whether or not they are provided as ports by a component in the same translation unit. Futhermore, if a component provides an interface that is not defined with the translation unit of that compoment, it is required that the user provide a #include directive to the appropriate E.idl file which contains the required LEM interface for the interfaces provided as facets. This new behavior is similar to the former behavior of -Glfa, and as such the behavior of -Glfa has been changed to attempt to be reflective of the old behavior of -Glem, and may be used as a stopgap backwards compatibility measure. . In idl3_to_idl2 tool, replaced manual designation of IDL2-only files and resulting generated include of undecorated filename (using -x option) with a mechanism that does it automatically. The -x option has been eliminated. USER VISIBLE CHANGES BETWEEN CIAO-0.7.2 and CIAO-0.7.3 ======================================================= . Added a first prototype of DDS4CCM . Added a first prototype of AMI4CCM . Made CIAO compiling with unicode enabled USER VISIBLE CHANGES BETWEEN CIAO-0.7.1 and CIAO-0.7.2 ======================================================= . CIDL compiler, and .cidl files, have been eliminated. All CIAO code generation is now handled by the TAO IDL compiler. See $TAO_ROOT/docs/compiler.html for details. . DAnCE has been refactored in separate libraries to reduce footprint and dependencies . Logging has been improved . IDL has been updated to match the official specifications . CIAO now also compiles on HPUX . Unicode improvements . Updated Quoter tutorial for all recent changes including the latest CosMIC releases . Use the new feature of the TAO_IDL compiler to generate all export files as part of the build step . Extended CIAO and DAnCE tests USER VISIBLE CHANGES BETWEEN CIAO-0.7.0 and CIAO-0.7.1 ======================================================= . No user visible changes in this release. USER VISIBLE CHANGES BETWEEN CIAO-0.6.9 and CIAO-0.7.0 ======================================================= . CIDLC compiler has new command line options: --suppress-lem which will suppress generation of the local executor mapping, --suppress-svnt which will suppress generation of the servant code, --lem-enclosing-module which will generate the local executor mapping inside a given module. USER VISIBLE CHANGES BETWEEN CIAO-0.6.8 and CIAO-0.6.9 ====================================================== . The CIAO refactoring branch has been merged to the main line of development. This version of CIAO contains extensive refactoring of the CIAO container code and includes a new version of DAnCE based on code provided by PrismTech. . Porting hints may be found at CIAO_ROOT/docs/Porting_Hints.txt . CIAO no longer supports implicitly homed components. This means that components must either be deployed using an explicity deployed and nominated home, or must be deployed without the use of a home. Unhomed components require new factory methods similar to those used for homes. These can be obtained by issuing the --gen-exec-impl operation to the CIDL compiler. . Extant deployment plans are no longer valid for this version of DAnCE. Until CoSMIC support is available, DANCE_ROOT/bin/generate_plan.py may be used to assist in the creation of well-formed deployment plans. . Names for most DAnCE executables have changed. Please see the Quoter tutorial found at CIAO_ROOT/docs/tutorials/Quoter for details. . DAnCE now supports connection endpoints realized by extra-plan object references. . Support for shared components and ReDaC has been removed with no immediate replacement planned. . Support for RTEC integration, RT-CCM, RepositoryManager, TargetManager, and staticly linked depoyment has not yet been ported to the new CIAO/DAnCE. . CIAO/DAnCE now supports by Xerces 3.X and 2.X. . Note that CoSMIC support is not currently available for this version of CIAO/DAnCE. USER VISIBLE CHANGES BETWEEN CIAO-0.6.7 and CIAO-0.6.8 ====================================================== USER VISIBLE CHANGES BETWEEN CIAO-0.6.6 and CIAO-0.6.7 ====================================================== . Added the "CIAO" OCI Development Guide Examples under the directory /DevGuideExamples. NOTE this is an ongoing port of the original version x.5.x examples and some are not yet 100% compatiable with the current version of CIAO. USER VISIBLE CHANGES BETWEEN CIAO-0.6.5 and CIAO-0.6.6 ====================================================== . None USER VISIBLE CHANGES BETWEEN CIAO-0.6.4 and CIAO-0.6.5 ====================================================== . None USER VISIBLE CHANGES BETWEEN CIAO-0.6.3 and CIAO-0.6.4 ====================================================== . None USER VISIBLE CHANGES BETWEEN CIAO-0.6.2 and CIAO-0.6.3 ====================================================== . None USER VISIBLE CHANGES BETWEEN CIAO-0.6.1 and CIAO-0.6.2 ====================================================== . Removed 24 unnecessary builds from the CIAO_TAO_DAnCE.mwc MPC workspace file . Changes to the generate_component_mpc.pl Perl scrip, CIDL compiler generation of empty executor implementation classes, and existing tests and examples to make servant dependency on executor the default, instead of vice versa as previously . Made the processing of IDL and CIDL files into separate build steps for tests, examples, and for DAnCE's TargetManager . Added additional tests for CIAOEvents Integration, which executes several scenarios for components using Real-time EventChannels as event mechanism. USER VISIBLE CHANGES BETWEEN CIAO-0.6 and CIAO-0.6.1 ==================================================== . Fixed broken static deployment support USER VISIBLE CHANGES BETWEEN CIAO-0.5.10 and CIAO-0.6.0 ======================================================= . Added support for building CIAO statically with Microsoft Visual C++ . Fixes to idl3_to_idl2 conversion tool, which - handle the mapping of IDL identifiers that are escaped (due to a clash with an IDL keyword) or that clash with a C++ keyword - handle the mapping of #includes of IDL files that aren't themselves processed by the tool USER VISIBLE CHANGES BETWEEN CIAO-0.5.9 and CIAO-0.5.10 ======================================================= . Extended IDL3_to_IDL2 USER VISIBLE CHANGES BETWEEN CIAO-0.5.8 and CIAO-0.5.9 ====================================================== . Added a new deployment algorithm to DAnCE for optimization of large scale deployment. In this algorithm, the number of threads spawned is based on the deployment plan, i.e, by parsing the deployment plan information, DAnCE decides how many threads to spawn (one thread per node). This algorithm knows how to "initialize" each thread since each thread will have different execution context, i.e., which components to deploy to which node, component configuration, etc. . Added a NA component server callback wait strategy in NAM, which uses conditional variable to signal the NA call back so it can work with multi-threaded configuration, such as thread-per-connection mode.

Enhanced DAnCE to support declaratively configure and deploy real-time event channels to mediate event communication among components. . Fixed a bug in detecting External connection and Internal connections when components are shared across different deployment plans. Earlier when removing connections attached to an external/shared component, not *all* connections associated with this components are purged from the to-be-removed connections list. . Fixed a bug when redeploying components using the same set of NodeManagers, the destroy of applications results not all internal components and external/shared components are unbinded from the cached map, which sometimes causes duplicate instance exception thrown. .

USER VISIBLE CHANGES BETWEEN CIAO-0.4.10 and CIAO-0.5.0 ======================================================= . Changed MPC configuration of Config_Handlers to turn off hidden visibility if applicable when compiling Config_Handlers or projects that use Config_Handlers on linux.This change was to work around symbol visibility inconsistencies in GNU standard C++ library when using g++ 4.x's symbol visibility features. . Enhanced ReDaC service to enforce the correct assembly redeployment and reconfiguration order. . Some bug fixes in ReDaC about removing components. . Fixed NodeApplication to unbind a component with naming service when removing it from the container. USER VISIBLE CHANGES BETWEEN CIAO-0.4.9 and CIAO-0.4.10 ======================================================= . Enhanced DAnCE ReDaC service to enforce the correct assembly redeployment and reconfiguration order. The order that ReDaC currently enforces: (1) Install new components, (2) Set up new connections, (3) Activate new components, (4) Passivate old components, (5) Remove old connections (6) Remove old components. . Enhanced DAnCE to create hierarchical naming context path through XML descriptors. . Enhanced DAnCE to maintain a component state map in the component server to manage component life cycle. . Some bug fixes in DAnCE. USER VISIBLE CHANGES BETWEEN CIAO-0.4.8 and CIAO-0.4.9 ====================================================== . RTTI enabled versions of the Xerces library are no longer needed on Windows platforms. . The CIDLC compiler now supports basic preprocessor directives: #ifdef, #ifndef, #else, and #endif as well as the -D command- line option. . The CIDLC compiler now supports incomplete struct and union semantics which will appear in CORBA 3.1. . DAnCE now supports dynamically adding/removing components to/from the existing running assembly without shutting down the running appliation. This will allow the application developers to evolve their applications on the fly without incuring service down time. The service is called ReDaC (Redeployment and Reconfiguration) Basically ReDAC provides a whole range of redeployment and reconfiguration granularity level, including: 1) Install/remove component instances of the existing component types. 2) Install/remove component instances of a different type, i.e., a totally new type of component. 3) Install/remove component instances from an existing container. 4) Install new component instances into a dynamically created brand new container. Move around existing components from one existing container to another existing/new container. 5) Install new component instances into another component server in the same physical node. 6) Install new component instances into another component server into a remote host. To see how to use this feature, please see the ReDaC-Usage.html under the $CIAO_ROOT/examples/Hello/ directory. . Removed the Old Config Handlers, which have been deprecated for some time. Please see tools/Config_Handlers for the current version. . Added a step-by-step CoSMIC tutorial for modeling CIAO components using PICML($CIAO_ROOT/docs/tutorials/CoSMIC). Using a simple Stock Quoter system as example, this tutorial demonstrates all the steps that needed to model Component-Based applications. . DAnCE now supports making connections among components across different assemblies, and allow components to be "shared" across assemblies seamlessly. Internally, DAnCE provides a reference counting mechanism when deploying/destroying components, and a reference count table is maintained on each NodeManager. From a deployer's point of view, if he/she chooses to deploy a new assembly of component and simultaneously wants to reuse previous deployed components in an existing running assembly, then in the new deployment plan descriptor, he could refer to an old component instance in the XML tag. The "key" to identify the old component instance is through the pair, if such a key is found present in a previous deployed assembly, then DAnCE won't install this component instance (specified by the ) again, but instead it will increase the reference count of this component instance. DAnCE also supports making connections from existing running components to newly deployed components in another assembly, and vice versa. . The RepositoryManager has been enhanced to support standards based interfaces. A number of techniques have been used to ensure high performance and scalability. . The RepositoryManager can now retrieve packages from remote locations via HTTP. . The Target Manager is released with this CIAO release. It is an infrastructure component which keeps track of resource usage in the target domain. The initial domain configuration remains with the Target Manager. A monitor framework has been built into Node Manager which monitors the resources used within each host. This monitor reports its data intermittently to the Target Manager which aggregates the data received across all such hosts acroos the Target domain. The monitor is implemented using a strategy pattern, thus enabling the plug-in of new monitors which can monitor different resources in the domain. The Target manager is a component thus it needs to be started using a deployment plan. It is right now a optional component in the DAnCE tool chain. . We added a skeleton implementation of the Resource Allocation and Control Engine (RACE) which is a middleware framework built atop CIAO/DAnCE that integrates multiple resource management algorithms for (re)deploying and (re)configuring application components. We are in the process of developing resource management algorithms (both resource allocation and control algorithms) that will be a part of future releases. USER VISIBLE CHANGES BETWEEN CIAO-0.4.7 and CIAO-0.4.8 ====================================================== . The deprecated RepositoryManager implementation, under DAnCE/RepositoryManager, has been removed from this release. Please use the Plan_Launcher and flattened deployment plans to deploy component assemblies. . The CIDL compiler frontend now supports constants, const expressions, bounded strings, bounded sequences, and arrays. . The CIDL compiler frontend now supports automatic indentation of function arguments (both "new line" and "same line" styles are supported). . Added backend CIDL compiler support for constants, arrays, bounded strings, bounded sequences, and attribute exceptions, corresponding to frontend support added by Boris Kolpackov . . Updated documentation to include instructions for building the CIDL compiler using MakeProjectCreator (MPC). . Fixed a bug in the CIDL compiler's determination if an IDL type is of fixed or variable size type, when it is declared in the scope of an interface, valuetype or home. . Changes to generate servant code to support component swapping. . Added capability to pass a base class event consumer to a subscribe() operation generated for a derived event type. . Added support for .cdl file extension, which was belatedly standardized by the OMG. . Added documentation on using Rational Purify with CIAO and DAnCE. . Added tests and documentation for the IDL3-to-IDL2 converter tool. . RepositoryManager: - enhanced the implementation to use various optimization techniques - added HTTP support - added PackageConfiguration visitor to update the locations of the implementation artifacts with relevant HTTP URLs - refactored some of the code and added a number of helpers functions . The XSC based config handlers have been heavily optimized, resulting in greatly reduced parsing overhead for large deployments. . The DAnCE toolchain now supports initializing attributes which have enumerated types. Support for other complex types is planned for the future. Please see examples/Hello/descriptors/ flattened_deploymentplan_without_ns.cdp for an example of how to populate enumerated attributes. . Integrated Real-time QoS support into the DAnCE-based runtime and deployment tools based on the new OMG Deployment and Configuration (D&C) specification. Such effort allows application developers to use real-time CORBA 1.0 features within their CCM appliation through meta-programming (via XML metadata through DAnCE toolchain). The old run-time and deployment tools based on original Packaging and Deployment section of the CCM specification have been completely removed. This work includes extensions to D&C schema, schema parsers, container and NodeApplication. . Added functionality in XML parsing code to resolve schema in $CIAO_ROOT/docs/schema instead of the local directory only. All DeploymentPlans should use Deployment.xsd instead of Modified_Deployment.xsd, which has been removed. . Fixed bug in CIDL code generation for some types of component and home attributes. . Packaging and Deployment (P&D) tools have been completely removed from this release. DAnCE is now the only supported method of deploying components. . The CIAO directory structure has changed in support of the previous item. The following important directory moves have been made: * $CIAO_ROOT/DAnCE/ciao => $CIAO_ROOT/ciao * $CIAO_ROOT/DAnCE/examples => $CIAO_ROOT/examples * $CIAO_ROOT/DAnCE/Config_Handlers => $CIAO_ROOT/tools/Config_Handlers * Various obsolete examples/tutorials/tests have been removed. . Error reporting during component deployment has been greatly improved. While debugging using CIAO_DEBUG_LEVEL is still available, detailed error messages are now generated and propagated to the Plan_Launcher using exceptions. . generate_component_mpc.pl has been updated to generate MPC files useful by the modern CIAO infrastructure. This script now also automatically generates export files. . DAnCE has been enhanced to support deploying multiple assemblies with the same set of ExecutionManager and NodeMangers. USER VISIBLE CHANGES BETWEEN CIAO-0.4.6 and CIAO-0.4.7 ====================================================== . Added a component packaging tool to DAnCE. This tool will allow component packagers to create from deployment plan archived packages that wrap up all relevant component properties, descriptors and implementation artifacts.The component packages generated from this tool will be distributed to Repository Manager. . Enhanced DAnCE to allow more than one NodeApplicationManagers within a NodeManager. . Enhanced DAnCE to support configurable output of debugging information. Support for debugging information will be added at the level of both the DAnCE/CIAO infrastructure as well as individual component instances. Support for tracing of the DAnCE/CIAO infrastructure will also be added. Together, these efforts will help developers to understand the execution of their component-based applications, as well as allowing customization of the amount of debugging information logged . Added binding component to the Naming Service. A system deployer could configure this through XML-based flattened deployment plan descriptor. See $CIAO_ROOT/DAnCE/examples/Hello/descriptors/flattened_deploymentplan.cdp for details. Currently DAnCE only provides resolving naming service reference through multicast, so be sure to initialize the naming service with multicast port. . Added the first cut of the RepositoryManager implementation. . Changed scoping of code generated by the CIDL compiler to accommodate cases where the composition declaration is enclosed in one or more IDL modules, and/or when the composition declaration is in a different scope than the associated component IDL declarations.

Added a test for the tool that converts IDL3 into equivalent IDL2. . Fixed CIDL compiler bug in code generation for sequence type attributes of components. . Added more examples for CIAO, including a new Quoter example that is similar to the one in TAO, as well as GUI-based example. . Added support for handle component activation/passivation in D&C assemblies. . Added support for deactivating facets/event consumers when component is getting deactivated. . Added support for destroying the component executors, when the component is getting deactivated. USER VISIBLE CHANGES BETWEEN CIAO-0.4.4 and CIAO-0.4.5 ====================================================== . Split the previous NodeApplication interface into NodeApplication and Container interfaces to allow multi-container NodeApplication support. This will be particularly useful to provide an optimized CIAO container support for RT-CORBA features. . Enhanced CIAO to handle dynamic replacement of components. Please see an example in $CIAO_ROOT/DAnCE/examples/Swapping . The Config Handlers have been modified to use XML parsing code generated by the XML Schema Compiler (XSC). Binary releases of XSC can currently be found at (http://www.dre.vanderbilt.edu/~boris/xsc), and a recent snapshot of the CVS repository can be found at (http://www.dre.vanderbilt.edu/~wotte/xsc.tbz2). Please direct all XSC inquiries/bug reports to wotte at dre.vanderbilt.edu . Supported initializing attribute values on Component through XML tags. Please refer to the $CIAO_ROOT/DAnCE/examples/Hello for details, particularly the Hello.cid descriptor file. . Supported parsing component instance names and using them to generate unique component port references, so that multiple instances of the same component can be deployed in a single container and the client requests could be properly designated to the appropriate ports. . Enhance CIAO to support establishing connections between derived type ports and base type ports. For example, application deployer could set up event connections between base event sink port type and derived event source port type. . Enhanced the existing set of DAnCE tools to support flattened Deployment Plan based deployment. Please refer an example in $CIAO_ROOT/DAnCE/examples/BasicSP/flattened_deploymentplan.cdp to see how the flattened deployment plan descriptor is used to deploy the BasicSP example. . Develop regression/performance tests (similar to TAO regression/performance tests) that will test/evaluate the performance of various features of CIAO. . Added regression test script to the nightly build for DAnCE example. This will make sure DAnCE tools could be ready to use out of box in various platforms. . Improved documentation pages in various places. . Some bug fixes. . Added support for reception of eventtypes of a more derived type than the type of the event sink. Subscription will succeed if the passed event consumer is associated with an eventtype that is an ancestor of the published eventtype. USER VISIBLE CHANGES BETWEEN CIAO-0.4.3 and CIAO-0.4.4 ====================================================== . Minor bugfixes. USER VISIBLE CHANGES BETWEEN CIAO-0.4.2 and CIAO-0.4.3 ====================================================== . CIDLC can generate empty executor implementations for a given composition, which makes it easier to write executors. This can be trigerred by passing --gen-exec-impl option while invoking CIDLC. . Generated container code has been refactored into base classes, thereby reducing the amount of code generated by CIDLC. . A new tool for generating equivalent IDL2 declarations from IDL3 declarations has been added. . Fixed a problem with DAnCE that prevented ports from getting activated properly. .

Added support for attributes in facets and supported interfaces. . Fixed bug in code servant glue code generation when there are multiple nested modules in the IDL and/or CIDL files. . Added missing code generation of enum type names. . Fixed a bug in the generation of the scoped name of a local variable which is a _var of an executor interface for a facet. These types are required by the CCM spec to be generated in the same scope as the interface that underlies the facet. . Fixed a bug in the generation of *S.h file includes corresponding to IDL files included in the CIDL file. . Added ACE style Makefiles. . Added support for bounded strings MPC === . Removed all of the project type specific and unnecessary keywords. . Changed the defaulting rules for idl files (generated source files will be automatically added even if idl files are explicitly listed). . The makefiles generated by the gnuace type are now named GNUmakefile instead of Makefile. . The IDL_Files section is no longer a built-in MPC type. It is a custom build type defined in taoidldefaults.mpb. . Added support for Borland Makefiles that aren't tied to ACE_wrappers (the bmake project type). . Added wild-cards to the default.rel file. Now, environment variables that end in _ROOT are automatically considered as if they were used with the -relative option. . Added an environment variable, MPC_DEPENDENCY_COMBINED_STATIC_LIBRARY, to force MPC to put inter-project dependencies in static vc6 and vc71 workspaces. . Added an html project type (originally by Justin Michel) to aid in the debugging of mpc files. . Added a new keyword, pure_libs, that is put into a project unmodified (unlike the libs and lit_libs keywords). . The behavior obtained through the use of the -hierarchy option is now the default for all "make" based project types. This includes borland, bmake, gnuace, make and nmake. . Added support for referencing workspace files (.mwc) from within other workspaces. . Added an option, -genins, that causes MPC to generate .ins files that can be used with prj_install.pl. This will help users install portions of their projects into alternate directories. . Modified the gnuace workspace output to be based on directory recursion instead of having inter-project dependencies built into each workspace level GNUmakefile. . Added a new keyword, dependent, for use within a Define_Custom that causes MPC to add a dependency to generated files upon the custom command. . Assignments within a 'specific' section that are not recognized MPC keywords are assumed to be template value overrides (similar to using the -value_template option). . Partial support for Visual SlickEdit has been added. . Various bug fixes and optimizations have been added as well. USER VISIBLE CHANGES BETWEEN CIAO-0.3.6 and CIAO-0.4 ==================================================== . Added Makefiles to build the ciao and tools subdirs by default. . The suport for the following IDL features have been added to the CIDL since the last beta - exception (exception declaration and raises() specification) - valuetype - enum - const declaration - const expression and literals - native - home finder - oneway operation - readonly attribute - type declaration inside interfaces, valuetypes - union CIDL doesn't yet support the following features - Complete error detection and recovery - Attribute exception specification - Array - Bounded sequence - Fixed type - Floating-point and Fixed-point constant expressions & literal. though we plan to add this support over the next several months, depending on user/sponsor needs.
