------------------------------------
Summary: SCR configuration-pid from compendium 4.3
Key: FELIX-3524
URL: https://issues.apache.org/jira/browse/FELIX-3524
Project: Felix
Issue Type: New Feature
Components: Declarative Services (SCR)
Reporter: Pierre De Rop
Priority: Minor
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.
