Subject [jira] [Commented] (KARAF-6000) Add direct resource repositories support
Date Mon, 05 Nov 2018 08:28:00 GMT

Guillaume Nodet commented on KARAF-6000:
----------------------------------------

Not exactly sure to understand how far you want to go.

Adding / removing resource repository is not a problem.  Currently, the "globalRepository"
is considered static, i.e. it's only read when the features-core bundle is started.  If we
want to make is more dynamic and have the ability to add / remove repositories at runtime,
we need to ensure we resolve the deployment again when a repository is removed / added, or
that we force the uninstallation of the resources that come from that repository in order
to make sure we always stay consistent.

About the "complete alternative to features": at runtime, a feature is translated into a resource,
but not a bundle resource, so we could translate a feature repository into a resource repository
very easily.  That said, a lot of things that are built into features can't be modelled just
using bundles as resources.  I think one good thing would be to have a command that translate
a feature or a feature repository into a resource repository so that we can have a better
idea of how things are modelled and how verbose/complex it would be to achieve the same without
features (I'm thinking about conditionals, the dependent flag, etc...).

> Since OSGi R6, the "new" bundle repository spec allows to directly leverage any requirement/capability
to do the bundle resolution.
> We already support this via the features (using {{resourceRepository}} with json or XML
in {{etc/org.apache.karaf.features.cfg}}. I think it would be great to have a complete alternative
to features using bundle repository. We could introduce a minimal feature set (just for the
bootstrapping) as we have today, but delegating to {{etc/org.apache.karaf.repository.cfg}}
for resource repositories and using them for resolution.
> We could also provide specific commands to manipulate the bundle repositories (like add,
remove, as we have for features repositories).
