----------------------------------
The above comment is unclear. I replied on the email thread with in-line
remarks and Jira seems to have removed my remarks from their context.
> Expose the "aborted" flag for transferred deliveries
> ----------------------------------------------------
>
> Key: PROTON-1512
> URL: https://issues.apache.org/jira/browse/PROTON-1512
> Project: Qpid Proton
> Issue Type: New Feature
> Components: proton-c
> Reporter: Ted Ross
> Assignee: Alan Conway
> Labels: api
> Fix For: proton-c-0.18.0
>
>
> As we develop support for message streaming in Qpid Dispatch Router (i.e.
> frames for large multi-frame messages are forwarded to destinations as they
> arrive, before the complete message is received), there is a need to handle
> the case where a received message is never completed.
> The AMQP protocol has a provision for this in the "aborted" flag in the
> transfer performative. If the router is in the process of streaming a large
> message from sender to receiver and the sender drops before completing the
> delivery, the router can send a transfer to the downstream receivers with the
> "aborted" flag set. This would indicate that the message should not be
> processed and would not cause any framing errors on the link.
> Proton does not currently expose this capability in its API (There is a
> pn_link_abort in the C header file, but it is commented out and not
> implemented).
> In order to properly handle the failure cases for message streaming, this
> feature must be usable in Proton.
