Subject Re: Features

L.S.,


Using the OBR resolver without helps a bit already, but in only helps in one
direction.  If you first install the newer bundle version (e.g. Spring
3.0.6), the OBR resolver will avoid installing 3.0.5 again.  But if the
first feature defines an older version (Spring 3.0.5) and you second feature
uses Spring 3.0.6, you're either getting only the old version of the bundle
or both versions (depending on the import version ranges of the other
bundles in the second feature).

For ServiceMix, I have been considering to generate an OBR repository.xml
that consists of all bundles found in all (karaf, cxf, servicemix, activemq)
features descriptors we use to fix this problem.  Another option could be to
use a single OBR in-memory repository for resolving all boot features and
only then switch to the per-feature resolver implementation we are currently
using.  Perhaps the latter is even a better option as it could benefit all
Karaf users without introducing any extra work for them while assembling the
container?
