Alan Conway created DISPATCH-112:
------------------------------------
Summary: Router fails with duplicate link ID errors.
Key: DISPATCH-112
URL: https://issues.apache.org/jira/browse/DISPATCH-112
Project: Qpid Dispatch
Issue Type: Bug
Components: Management Agent
Affects Versions: 0.3
Reporter: Alan Conway
Assignee: Alan Conway
Fix For: 0.4
Regression introduced in r1658584. Attempted to give links more "friendly"
management IDs but the IDs "link/<linkname>" are not unique. To be unique they
should also include the remote container name, which would make them less
friendly. Revert to using unique numbers for link IDs.
Problem description from email:
I found the commit where the bad results start happening. All subsequent
commits exhibit the same problem.

NO-JIRA: Minor fixes to management code.
- Get rid of defunct router_node refresh C code.
- Use linkName for router.link identity.
- Drop router.node addr attribute (replaced by address)
- Rename refresh as refresh_entity to avoid confusion with neighbor_refresh etc.
- Fix error-handling bug in agent.py

When I start a 6 node network, and then run qdstat on one of the nodes, I'm
getting an error and subsequent runs of qdstat return incomplete data.

qdstat -r QDR.C -c
BadRequestStatus: org.apache.qpid.dispatch.router.link: Duplicate value

When I revert to the previous checkin, I'm not seeing the problem.
