Bundle resolving runs extreme long
----------------------------------
Key: FELIX-977
URL: https://issues.apache.org/jira/browse/FELIX-977
Project: Felix
Issue Type: Bug
Components: Bundle Repository (OBR)
Reporter: Kristian Koehler
Hi
I encountered problems while resolving rependencies via the bundle repository.
Here is the scenario:
I have a simple obr file with a resource definition which has an unresolved
dependency. In this file the resource with the name "org.springframework.core"
has a requirement for the "org.apache.commons.logging".
When I start felix with the obr repository location poniting to that file and
type 'obr start com.kkoehler.osgi.repo-test' I'm gettiing the following:
--- 8< ---
Unsatisfied requirement(s):
---------------------------
(&(package=org.springframework.context)(version>=2.5.0))
Unnamed - com.kkoehler.osgi:repo-test:bundle:1.0-SNAPSHOT
(&(package=org.apache.commons.logging)(version>=1.0.4)(!(version>=2.0.0)))

I seems to me that felix tries to resolve the bundle "Spring Core" more than
once ;-)
The wrong unsatisfied dependency information can easily be fixed when checking
for existing information in the current list before added it
(org.apache.felix.bundlerepository.ResolverImpl). But I think this is only a
workaround for the problem of 'double resolving' (I also tried with a larger
project and the resolving seems to run 'endless').
In the ResolverImpl I found a statement which 'causes' my problem but there is
also a comment for the code.
--- 8< ---
// If the resource did not resolve, then remove it from
// the resolve set, since to keep it consistent for iterative
// resolving, such as what happens when determining the best
// available candidate.
if (!result)
{
m_resolveSet.remove(resource);
}

Removing the line solved my problem but I'm not sure if I'm running in new
ones...
Thanks
Kristian
