> Key: PROTON-1110
> URL: https://issues.apache.org/jira/browse/PROTON-1110
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: 0.11.1, 0.12.0
> Reporter: Robbie Gemmell
> Assignee: Robbie Gemmell
> Fix For: 0.13.0
>
>
> The engine emits synthetic Flow events when sending messages, in addition to
> those raised when receiving a Flow frame for the link. I believe the
> reasoning for this is so to treat it as a 'credit changed' indicator.
> However, as there are cases where the decision to send a message has little
> at all to do with the credit conditions, having these events its often
> unecessary and wasteful.
> A simple toggle will be added to signal the transport not to emit the flow
> events for use in those cases. The default behaviour will be unchanged.
