Current Status

1. The first cut of the new DnC specification implementation, which we call DAnCE is available in this distribution. DAnCE is housed under $CIAO_ROOT . We plan to enhance DAnCE in the next few months. We believe DAnCE will replace existing tool sets in $CIAO_ROOT/tools. There are a few features in $CIAO_ROOT/tools that are missing in the DAnCE implementation. Please see TODO file for more details. We plan to implement them soon and use DAnCE continuously.
2. The first cut of DAnCE includes two parts:
   • A modeling tool chain , CoSMIC, which is capable of describing the Assembly/Component using GME as the development bed. The artifacts generated from the CoSMIC are a set of XML descriptors.
   • This run-time infrastructure that performs the actual deployment and configuration, with a superset of the capabilities described in OMG DnC specification with CIAO extension. .

   In the new DnC run-time framework we have migrated all the functionalities present in the old CIAO runtime except the Real-Time configuration and Static Configuration, which are developed by Washington University in St. Louis. Currently, the two CIAO runtime co-exist in our source and the component implementation could be used with both framework without much change. (For the change that one has to go through please read this.)

3. Two operations ciao_preactivate () and ciao_postactivate () have been added to the SessionComponent interface. This implies that component developers have to implement those operations within the executor. We plan to get around this, i.e., users having to implement these two operations, in the next month or so.

4. Here is a set of updates in the CIDL Compiler.
   • Fixed bugs in generation of inherited: home operations, attribute operations, port operations, home factory operations, supported operations.

   • Added support for multiplex uses ports. This implies that users could use "uses multiple" in their component definitions.

   • Added automatic registration of value factories for event consumers. This has been long outstanding. This change alleviates component developers need to register the valuetype factory of their eventtypes with the ORB.

   • Added support for emits keyword and we now generate navigation code for this.

   • Fixed bug with multiple facets in a build that provide the same interface.

   • Implemented get_all_facets() and get_all_consumers() navigation methods.

5. CIAO doesn't yet support features that help integrating CORBA components with Enterprise Java Beans (EJB).
