---------------------------------
> Make resolver more robust
> -------------------------
>
> Key: FELIX-285
> URL: https://issues.apache.org/jira/browse/FELIX-285
> Project: Felix
> Issue Type: Improvement
> Components: Bundle Repository (OBR)
> Affects Versions: 1.0.0
> Reporter: Bart Elen
> Assigned To: Richard S. Hall
> Fix For: 1.0.0
>
> Attachments: ResolverImpl.java
>
>
> There are two issues with the resolver of the current OBR implementation:
> 1) It does not try each possible composition
> Suppose we want to install bundle A, and A has a requirement which can be
> fulfilled by bundle B or C. B itself has a requirement which can be fulfilled
> by bundle X and bundle C has a requirement which can be fulfilled by bundle Y.
> A-B-X
> A-C-Y
> Suppose now that bundle X is not available (or can not be installed on the
> local platform)
> A-B-
> A-C-Y
> composition A-C-Y is now a correct composition, but the current
> implementation will notice that bundle B can not be resolved and will then
> stop. OBR will not always detect the correct composition.
> 2) Bundles are not always updated
> Suppose we want to install bundle A which has a requirement which can be
> fulfilled by bundle B.
> A-B
> An old version of bundle B is already locally installed on the platform but a
> newer version is available on the repository server. The current OBR
> implementation will detect that the requirement of A can be met by the
> locally installed old version of B and it will not check for a newer version
> on the repository server.
> I attached a fixed version of ResolverImpl.java in which the described issues
> are fixed.
> This is my first issue submit ever. Feedback to make it better is appreciated.
