Hi Jens,

[Scott]  Do you expect these to be implemented via ConfigurationPlugins?

I have no expectations at the moment ;-) But if you have a good idea. let's discuss it!

[Scott]  FWIW, I do think that if possible, it would make sense to use the ConfigurationPlugin extension mechanism for ConfigurationAdmin.  We/Intel may have to create a ConfigurationPlugin ourselves that uses Metatype so I've been looking into this recently.

I don't think that all things can be achieved by the ConfigurationPlugins btw, some may be. But not all.

 

I already looked into the Equinox CM in the base, due to some bugs I encountered. It is quite .. well ... suboptimal. So I switched to Apache Felix CM. Which works great! I also heard a bit about a reference implementation for the OSGi R7 CM.

[Scott]  From where/whom?   If you have any info about that please post any links.   Also...are the R7 spec additions for CM significant?  Do you happen to know the RFP?

From a someone attending a talk at EclipseCon 2016 about that  ;-) That is why I am a bit careful about that before I dug into this myself!

 

So my plan was to look into R7 and then maybe build something based on top of that or based on Apache Felix CM. And of course look for anything else "out there" before implementing something. So if you have a good idea, now would be the best time ;-)

[Scott]  FWIW, unless there is something in R7 that just can't be lived without, I suggest using the R6 (rather than R7) spec and full impl (e.g. Felix CM).   

That was my intention as well, but maybe R7 provides more stuff which we would need. But yes, it has to be evaluated. And I agree, unless there is something really helpful, then stick with Felix. Or some other "non-Equinox" implementation. Because the Equinox implementation is not a good choice IMHO.

Cheers

Jens
