Subject [jira] [Closed] (DISPATCH-189) Dispatch python tools fail to detect rejected connection
Date Mon, 02 Nov 2015 22:03:28 GMT

     [ https://issues.apache.org/jira/browse/DISPATCH-189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chuck Rolke closed DISPATCH-189.
--------------------------------
    Resolution: Not A Problem

The faulty code is in qpid-proton and not in qpid-dispatch.

>                 Key: DISPATCH-189
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-189
>             Project: Qpid Dispatch
>          Issue Type: Bug
>          Components: Management Agent
>    Affects Versions: 0.5
>         Environment: qdstat tool connecting to broker/router that rejects the connection
>            Reporter: Chuck Rolke
>            Assignee: Chuck Rolke
>
> Case 1: connection rejected by qdrouterd:
> -----
> Testing out policy-based connection rejection shows qdstat tool mis-interpreting the
connection failure. The order of events on the wire is:
> {noformat}
>  Client sends 
>     Open
>  Router sends 
>     Open
>     Close(Arguments: Error: {
>       Condition: 'amqp:resource-limit-exceeded',
>       Description: 'connection disallowed by local policy',
>       Info: ''}
> {noformat}
> Then the qdstat tool fails with message:
> {noformat}
> AttributeError: 'ConnectionClosed' object has no attribute 'url'
> {noformat}
> The expectation is for the tool to show the condition/description from the Close performative.
> Case 2: connection rejected by Apache Qpidd C++ broker
> -----
> When Qpidd rejects a connection it summarily closes the connection with a TCP FIN and
does not exchange AMQP Open. In this case the qdstat tool displays a reasonable message about
connection failure to $management.
