Enhance Execution Manager and Domain Application Manager to make calls - on the Target Manager to get resource information. - -. Enhance Node Manager to integrate resource monitoring capacity within - individual Nodes. - -. Add assembly-wide component activation/deactivation feature. - - - This should allow system deployers to specify the dependencies - among component instances within the assembly. - - - Add support in DAnCE so DAnCE could enforce the order in which - components are to be activated within the assembly. - -. Add AMI support in DAnCE toolchain to when the DomainApplicationManager - contacts node-level managers to deploy components, all the node-level - managers could performe the deployment concurrently. - -. Integrate RT-CORBA 1.2 dynamic scheduling feature into CIAO, which - will allow the application developers to use dynamica scheduling - through meta-programming model. - -. Enhance DAnCE to support OpenCCM components. - -. Update DAnCE IDL data structures and interfaces to comply with the - 06-02-01 version of the DnC specification, and perform - interoperability testing with other DnC implementations. Note this - work may change the functionality and semantics of some proprietary - DAnCE extensions, notably ReDaC, Shared Compoents, and RTEC - integration, and may even be absent until such a time as they - can be implemented in such a way as to not break copliance with the DnC - specification. - -. Implement Resource Allocation and Control Engine (RACE), which is a - component middleware framework built atop of CIAO/DAnCE that integrates - multiple resource allocation/control algorithms for (re)deploying and - (re)configuring component applications. RACE enables (1) system - developers to configure algorithms depending on the characteristics of - applications and operating environment, and (2) swapping in and swapping - out multiple algorithms to make different resource allocation and control - decisions, without handcrafting the mechanisms needed to (1) configure - the algorithms and (2) deploy the decisions made by the algorithms. - -. Implement support for more complex type initialization with XML. - -. Decouple dependencies to NodeApplication from other DAnCE tools. - These dependencies were added to support static configurator. We - need to have these tools in both conventional version and static - configuration version. - -. Support tool-specific debug levels and added CIAO_DEBUG macros to - simplify adding debug printouts based on various tool-specific debug - levels. - -. Add support for querying for interface types to the - RepositoryManager. - -. Implement a planner to query the TargetManager and RepositoryManager - and generate deployment plans on the fly. - -USER VISIBLE CHANGES BETWEEN CIAO-0.5.3 and CIAO-0.5.4 -====================================================== - -. Adding support to manage multiple interconnected assemblies, which will - involve the work through ExternalReferenceEndPoint idea. - -. Seamless integration of swapping into the main line programming model, - so that DAnCE can actually kickstart swapping. - -. Integrated real-time event service into CIAO and DAnCE. - -.

Reimplemented the findNamesByType () and getAllTypes () operations of - RepoMan, which use the newly generated ACE_Hash_MultiMap_Manager class - and its corresponding classes. - -. Added Plan_Generator project. This project is used to retrieve information - from Repoman and generate/modify DeploymentPlans based on different demands. - -. A succesfull static deployment of the Hello example has been tested on - VxWorks 6.3 - - -USER VISIBLE CHANGES BETWEEN CIAO-0.5.2 and CIAO-0.5.3 -====================================================== - -. Improve documentation for CoSMiC Quoter tutorial to reflect the latest update - -. Reimplemented the findNamesByType () and getAllTypes () operations - of Repository Manager, which use the newly generated - ACE_Hash_MultiMap_Manager class and its corresponding classes. - -. Added the replace argument in installPackage () and createPackage () - functions to Repoman and extend the functionalities of these two - functions based on the latest D&C spec. - -. Added the Plan_Generator project. This project is used to retrieve - information from Repoman and generate/modify DeploymentPlans based - on different demands. Removed the planner project. - -. Added C++ keyword mangling to the CIDL compiler (bug#2427). - -. Fixed the CIDL compiler source code to build with Intel C++ (bug#2387). - -. Reimplemented the CIDL compiler command line handling to make use - of '--' to separate options from arguments unnecessary (bug#2426). - -. Added file and line number to the semantic errors printed by the CIDL - compiler. - -. Fixed a number of bugs in the CIDL compiler error handling and recovery - mechanisms. - -USER VISIBLE CHANGES BETWEEN CIAO-0.5.1 and CIAO-0.5.2 -====================================================== - -. Changed CIDL compiler code generation for facet servant classes - to enable reuse if the same interface is used as a facet more - than once in a single translation unit. - -. Fixed code that fetches component DLL entry points to be portable - across all supported compilers. - -. Fixed bugs in the recent implementation of component servant methods - get_all_receptacles() and get_all_publishers(). - -. Simplified template code in component servant and home servant - base classes. - -. Added the naming service & the implementation of createPackage function - to RepoMan. - -. Added the code to save the state of the RepoMan at exit and load the - state of it at start. - -. A new perl library has been added to the bin directory. PerlCIAO is - a wrapper around PerlACE with extensions to aid in scripting CIAO - tests. - -. DAnCE/Planner - a planner which contacts the RepositoryManager, gets a - PackageConfiguration by name, and builds a DeploymentPlan on - the fly. Note that the node information is currently not populated. - -. Added two RACE utilities, the LocationUpdater and PlanGenerator. - The LocationUpdater modifies the location field of artifacts in - flattened plans to correspond to HTTP URLs pointing at the - RepositoryManager. The PlanGenerator is the Planner utility - modified to work with RACE. Note that most RACE functionality is - still in development and is not included with this release. - -. Added support for parsing packaging descriptors to the - Config_Handlers, and improved support for IDL->XML serialization. - -. Added a Planner utility which, when given the name of a package, - will contact the RepositoryManager and construct a flattened - deployment plan on the fly. Note this utility currently does not - populate node assignments. - -. Several important bugfixes for ReDaC and shared components. - -. Changed Components.idl to include CCM_Component.idl instead of - CCM_Container.idl. This removes a dependancy on the container - library for stub projects. - -USER VISIBLE CHANGES BETWEEN CIAO-0.5.0 and CIAO-0.5.1 -====================================================== - -. Added the support of integrating real-time event service into the - CIAO core framework. 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. - -. Fixed bug in detecting name clashes between names of ports of the same - category (facet, event sink, etc.) in the same component. - -. Added support for attribute exceptions in code generated for executor - implementation classes. - -. Implemented spec-defined component methods get_all_receptacles(), - get_all_publishers(), and disconnect_consumer(). - -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 <InstanceDeploymentDescriptions> - XML tag. The "key" to identify the old component instance is - through the <Component_UUID, Node> pair, if such a key is found - present in a previous deployed assembly, then DAnCE won't - install this component instance (specified by the <Component_UUID>) - 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 <boris@kolpackov.net>. - -. 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. - - -USER VISIBLE CHANGES BETWEEN CIAO-0.4.5 and CIAO-0.4.6 -====================================================== - -. Added support for handle component activation/passivation in D&C - assemblies. - -. Added a test for the tool that converts IDL3 into equivalent IDL2. - -.

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.

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.
