Hi,
I go on my investigations about an OBR for Felix. I'm working on writing
descriptions for all released bundles. Indeed, Bindex generate correctly
package capabilities and requirement in term of package, but is not very
useful about services. The maven-bundle-plugin allows to customize / improve
descriptions. So, my goal is to create these descriptions ASAP (and to try
to discover these descriptions automatically). These descriptions will
greatly help the deployment process as service requirements will be computed
as well as packages.
Yes, that would be a good idea.
However, this open new issues... we have one artifact
(web console) that requires the HTTP Service that was not released (correct
me if I'm wrong). So, the generated repository is not self-contained.
Hmm. We should probably just go ahead and release HTTP Service.
Another small issue is about bundles depending on SCR. The SCR runtime
deployment is not automatic as it's neither a service requirement nor a
package requirement. One solution is to add a specific capability to SCR,
and to create a requirement targeting this capability in each bundles
requiring the SCR runtime. In fact, if we go further, this issue will appear
for each extender model (when an extension is deployed before the host).
Yes, this is an issue. As you say, the only way to resolve it currently
would be to add custom capability/requirements in the SCR and client
bundles. Not much else we can do. At best we can define something to put
in the manifest so that bindex can pick it up and generate the
appropriate dependency.

Sounds good to me...we might quickly find, though, that we need to
revise how OBR reads the repository files, since currently it reads them
every time it starts...perhaps we could cache them for some
[configurable] time so that it doesn't have to go download repository
files all the time...still, I think it is a good idea..
Sounds good. We could that simply by leveraging the Caching headers of
the HTTP protocol, such as Last-Modified and ETag.
Now we just need to finish up with what Clement created to generate our
desired Felix OBR repo...
Yes.

Hi all,
After adding OBR referral support (with hop count) as per FELIX-399
recently I started with prototyping a setup for this functionality. I
have created a "master repository" at [1] which contains referrals to
the Sling repository at [2] and Clement's prototype at [3].
If you update your felix framework to the latest 1.1.0 SNAPSHOT build
of the bundlerepository project, which I just deployed to [4], you can
add the master repository, for example typing in the Felix Shell
obr add-url http://people.apache.org/~fmeschbe/repository.xml
Listing the existing repository URLs should then give you all three
mentioned above.
Now, what does this help ? IMHO this proves the idea, that we can have
a single master repository referring to other repositories without
requiring to duplicate entries.
So we could provide such a master repository at our site, e.g.
http://felix.apache.org/repository.xml (this is not there yet ;-) ).
And upon requests by projects we might add referrals of a defined
depth (I would say 1 by default, but not too big, either).
WDYT ?
Regards
Felix
