Tuomas Kiviaho commented on FELIX-4600:
---------------------------------------
As one can see from fiddling with the description, I invested a bit time to
think this through and get things working for me. A simple {{propagate}}
attribute to {{@AspectService}} and {{@AdapterService}} would be enough.
{{AdapterImpl}} should not divert calls to {{propagateAdapteeProperties}} when
propagation is not wanted to happen automagically. It can be done manually at
{{@Start}} method where unwelcome properties can easily be omitted.
> Cherrypicking of propagated properties

> Key: FELIX-4600
> URL: https://issues.apache.org/jira/browse/FELIX-4600
> Project: Felix
> Issue Type: Wish
> Components: Dependency Manager
> Affects Versions: dependencymanager.annotations-3.2.0,
> dependencymanager.runtime-3.2.0
> Reporter: Tuomas Kiviaho
>
> Currently osgi.command.scope and osgi.command.function flood down from my
> {{@AdapterService}} because there is no propagation prevention mechanism as
> per {{@BundleAdapterService}} (also mentioned at FELIX-4594). This also
> applies {{@AspectService}} annotation.
> Still with these options the propagation from adapters/aspects is currently
> uncontrollable compared to dependencies where - albeit cumbersome - you still
> can write your own logic.
> My use case is with propagated adapter/aspect identity properties (such as
> service.pid, jmx.objectname, osgi.command.scope, osgi.command.function) that
> I'd rather not see automatically propagated.
> -There is already a {{setPropagate(Object, String)}} method in
> {{ServiceDependency}}. I think this mechanism could also be available for
> annotations alongside the {{propagate}} boolean property. (Perhaps a
> {{String propagated() default ""}})-
> -I suggest that internal m_serviceProperties would be changed as map (since
> @Start annotation allows this already) and keys with null values would be
> considered non-propagable. Internal map would be converted to Dictionary each
> time in passes API/Impl boundary and at this point keys with null values
> would be dropped.-
