Ernest Allen created DISPATCH-883:
-------------------------------------
Summary: Router crashes when it processes management request for
connections
Key: DISPATCH-883
URL: https://issues.apache.org/jira/browse/DISPATCH-883
Project: Qpid Dispatch
Issue Type: Bug
Components: Container
Affects Versions: 1.0.0
Reporter: Ernest Allen
Router crashes when attempting to service a management request.
When a python client sets its connections properties to a map, then as soon as
the router receives a management request for the connection info, the router
will crash.
If the client sets its connections properties to a string, then there is no
crash.
To reproduce:
- start the router using tests/config-1/A.conf
- modify the proton example server.py to set a properties map on line 37:
self.conn = event.container.connect(self.url,
properties={'client_identifier': 'policy_server'})
- start the modified proton example: ./server.py -a 0.0.0.0:20000/example
- all is well until you do a qdstat -b 0.0.0.0:20000 -c
