Dominik Süß commented on SLING-5014:
------------------------------------
[~bdelacretaz] this might be orthogonal. Anyways it might be possible that the
candidates come from other arbitrary installers that the instance cannot
control (immutable). Unless we do a breaking api change that mandates install
providers to be able to handle cleanup we have no reliable way to enforce such
a cleanup. For the repo we additionally have the case that users might
"accidentially" reinstall packages containing harmful bundles that can tear
down a complete instance completely. Therefore I think this safety net is very
reasonable while I agree we should also look for a mechanism to clean up where
we can.

>
> In case a bundle has mutliple install candiates only the highest version
> (with the highest priorty for the same versions) wins. An uninstall directive
> in the Sling bootstrap.txt file or provisioning model uninstalls this
> version. The way the OSGi install behavior is defined this lets the next
> artifact in the priority queue to get active and consequently only leads to
> downgrade to the next in the queue.
> As the uninstall directive declares a range that should be uninstalled the
> expectation is that after a startup with such an uninstall directive none of
> the declared versions are in an installed state. In consequence the OSGi
> installer must save this metainformation in the state that prevents a
> downgrade to a version that is part of an active uninstall directive.
