Mdu created FELIX-5365:
--------------------------
Summary: Generate warning on service published and consumed on
same interface but different bundles
Key: FELIX-5365
URL: https://issues.apache.org/jira/browse/FELIX-5365
Project: Felix
Issue Type: Improvement
Components: Dependency Manager Shell
Affects Versions: org.apache.felix.dependencymanager-r8
Environment: Eclipse Mars/Bndtools 3.x
Reporter: Mdu
Priority: Critical
Fix For: org.apache.felix.dependencymanager-r9
Scenario:
1. Service S1 is published on interface from package a.b.c exported by bundle
B1.
2. Component C1 requests (depends on required=true) S1 using an interface from
package a.b.c exported by bundle B2 (or its own bundle).
3. Component C1 stays unresolved due to missing S1 even though S1 is
successfully registered and available.
Root Cause:
Services are considered different if an interface they export is from 2+
different bundles.
Feature Improvement Request:
It'd be a time-saver for troubleshooting purposes for "dm wtf" command to warn
of this subtle mismatch.
A warning could be:
Component C1 is waiting for a dependency on interface 'a.b.c' published under
package a.b.c exported by bundle B2. There exist a potentially matching service
published under interface of the same name but exported by bundle B1.
