Ken Giusti updated DISPATCH-2018:
---------------------------------
Priority: Critical (was: Major)
> Improper handling of link refusal when destination peer for link-routing goes
> away
> ----------------------------------------------------------------------------------
>
> Key: DISPATCH-2018
> URL: https://issues.apache.org/jira/browse/DISPATCH-2018
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 1.14.0
> Reporter: Robbie Gemmell
> Assignee: Ken Giusti
> Priority: Critical
> Fix For: 1.17.0
>
>
> In case of a router doing link routing to a broker, which goes away during an
> error handling test, the router can then need to refuse new links and/or kill
> existing links as it has nowhere to route them. That is all to be expected.
> When failing to attach some sender links though, it was observed the router
> in one case did not response to a clients attach at all, and in a second case
> incorrectly sent a response attach with a populated target, having address =
> null, followed by a detach with error (which looks to lead to some unexpected
> client behaviour as it was mislead into thinking the producer actually
> opened, likely exposing a separate client issue).
> The attach in the second case should have had target=null, rather than a null
> address, to indicate that this was a link refusal and the detach with error
> would follow:
> {noformat}
