Re: [kura-dev] question about kura's configuration service

[Jens Reimann <jreimann@xxxxxxxxxx>]

Hello Scott,

"develop" is 3.0.

Technically what is happening is that the Kura configuration service does forward all configuration updates to the OSGi ConfigAdmin. Which actually overwrites everything which is in the OSGi ConfigAdmin. It also only works with the Equinox ConfigAdmin, there is some issue when using the Felix ConfigAdmin which causes duplicate entries. I am not sure what causes this up until now but I am not sure if it is worth tracking this down.

There are some know oddities with the Kura ConfigurationService and my hope is that we can replace the Kura ConfigurationService with the default OSGi ConfigAdmin in the 3.0 release cycle or in the following release.

My idea is to only use the OSGi ConfigAdmin and provide a set of addons to that, implementing the features Kura need (encryption, rollbacks, import/export). But sticking to standard OSGi functionality and tooling for all the rest.

Cheers

Jens

Hi Folks,

In the javadocs that I can find for the ConfigurationService [1] it says that the Kura ConfigurationService works in concert with the OSGI ConfigurationAdmin and OSGi MetaTypeService services.

Does this mean that the Kura ConfigurationService can run in concert with the Felix ConfigurationAdmin impl that's in Karaf> (newer version of OSGi config admin, ds, and meta-type services)?  Is that on 3.0 branch?  Are there any docs on how the OSGi ConfigAdmin, metatype, and Kura ConfigurationService work together?

Also WRT 3.0 branch, what is the 3.0 branch called in the github repo?   When browsing I see master and develop, but not an obvious 3.0 branch (like there are for previous/current releases).

Thanks,

Scott
