[jira] [Assigned] (DISPATCH-962) links established to 'unavailable'
addresses are not refused correctly
[ https://issues.apache.org/jira/browse/DISPATCH-962?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ganesh Murthy reassigned DISPATCH-962:
--------------------------------------
Assignee: Ganesh Murthy
> links established to 'unavailable' addresses are not refused correctly
> ----------------------------------------------------------------------
>
> Key: DISPATCH-962
> URL: https://issues.apache.org/jira/browse/DISPATCH-962
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 1.0.0, 1.0.1, 1.1.0
> Reporter: Robbie Gemmell
> Assignee: Ganesh Murthy
> Priority: Major
>
> When setting an address as unavailable (via defaultDistribution: unavailable from DISPATCH-803) the router doesn't refuse the links to it in the manner the spec indicates it should.
> To indicate a link is being refused, the spec describes that the attach response should contain a null target/source as appropriate, essentially indicating to the peer that the detach will follow due to the error, [http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#doc-idp315568], Figure 2.33: Refusing a Link.
> Currently this does not happen, e.g:
> Creating a sending link, response attach with non-null Target:
> {noformat}

> {noformat}
> The links are detached after this, but the non-null terminus removes the hint to the peer that it is coming.
