DISPATCH-231 - Don't issue credit on targeted incoming links until there is at
least one consumer for the target address.
> Router should not issue credit for unavailable targets
> ------------------------------------------------------
>
> Key: DISPATCH-231
> URL: https://issues.apache.org/jira/browse/DISPATCH-231
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 0.5
> Reporter: Ken Giusti
> Assignee: Ted Ross
> Fix For: 0.6
>
>
> When a client creates a sending link to a target, the router accepts the link
> on behalf of the target, and issues credit.
> This happens even if the target is unknown (eg. no consumers exist).
> In this case, the client will send a bunch of messages that simply stall or
> are released.
> As an alternative, the router should only issue credit if the target is
> available.
> Specifically:
> 1 - on attach, do not issue credit if the target is not available
> 2 - if the target goes away, stop issuing additional credit
> #2 can result in in-flight messages being left in limbo. In this case, it is
> acceptable to drop those messages that have been sent pre-settled, and
> release those messages sent unsettled. Ideally, the router would hold on to
> these messages for a short time (TTL?) and re-send if the target becomes
> available in that time.
