Re: Generating a repository.xml for Felix OBR

I started implementing the OSGi Repository service API for Felix OBR
[1]. Currently I'm taking the approach of providing this service as a
façade over the existing OBR functionality. So it's backward
compatible, although I think that for certain things the main OBR code
may need to be enhanced.

If nobody complains I'd like to simply start adding things for this to
felix/trunk/bundlerepository, making sure that the existing tests
don't break. Ok with everyone?

Cheers,

David

No not quite - I'm planning to provide an OSGi Respository Service
implementation (OSGi Enterprise Spec chapter 132) in the Felix OBR
subproject. It should be able to read both the proprietary Felix OBR
xml as well as the spec-compliant repository xml and will provide an
instance of the OSGi Repository Service in the service registry...

So you're going to provide an OBR index derived from an R5 index?
Seems kind of pointless to me, since the OBR format is considered 
'deprecated'.

That repo is kind of at a stand-still.
Nowadays bindex is developed at https://github.com/bndtools/bindex

If you're talking about an R5-compliant xml, no I wasn't planning on
providing that, but I am planning to extend the Felix OBR runtime so
that its able to read it. I think to provide the R5-compliant
repository.xml people will probably want to use
https://github.com/osgi/bindex

You are correct that the R5 xml is more expressive than the OBR XML.
So to support reading that the internal OBR representation will
probably need to be expanded a bit. I'd rather have one runtime entity
though, that supports both the Felix-OBR way of accessing it as well
as the OSGi R5 Repository Service API, rather than creating two
separate ones, TBH.

But I've only looked at this for a few days now, so I might have to
change approach if I hit a roadblock...

Cheers,

David

So you're going to provide an R5 index, derived from OBR?

I think that will ultimately not work out, since the R5 format is way 
more expressive than the OBR format.
I'd just provide an R5 index directly from the artefacts

Perfect. Thanks, David

I think this code deserves some love :-)

Re: Generating a repository.xml for Felix OBR

Posted by David Bosschaert <da...@gmail.com>.
Just a quick update on this...

I have added an OSGi spec-compliant Repository Service to OBR. At this
point all the OSGi Repository 1.0 CT tests pass with it.
For more details see https://issues.apache.org/jira/browse/FELIX-4368
(and sub-issues).

I haven't tried it in anger yet, so it would be great if people start
playing with this :)

Cheers,

David
