> This issue is about implementing the new "configuration-pid" component
> attribute specified by the OSGi 4.3 compendium. So far, components were using
> the component name in order to retrieve the component configuration from
> config admin. But In the section 112.4.4, a component can now define an
> optional specific configuration-pid, in order to use a PID which is different
> from the component name.
> I have attached to this issue a proposed candidate patch, if someone could
> review it and hopefully commit it.
> I have not yet made a unit test, but if my propose patch seems reasonable and
> is accepted, then I will try to learn to implement the corresponding test.
> Here is a brief description of the patch:
> - first the parser (XmlHandler/ComponentMetaData) has been modified in order
> to parse the new configiration-pid attribute from the component element (the
> parsing fails if the version is not greater or equals to DS 1.2).
> - next, in ComponentRegistry.java, we are now holding the mapping between
> configuration pids and their respective components: a new method
> getComponentHoldersByPid(String pid) method has been added, and returns the
> iterator on the ComponentHolders which must be configured with the given pid.
> Please see comments in patch.
> - in ConfigurationSupport.java: when a configuration update is detected from
> config admin, then the updated is notified to all components whose
> configuration-pid are referencing the updated pid.
> thanks.
