>From a IRC conversation with Rob:
{noformat}
<rgodfrey> [...] we need to have a way of leaving the session in a state where
there is an incomplete multiple frame transfer in progress
<rgodfrey> which will only complete when more session credit arrives
[...]
<rgodfrey> [this means] that we need to implement the consumer state thing above
<rgodfrey> since it will have to interleave sending parts of the message and
then receiving flows
[...]
<rgodfrey> In general terms I think that a consumer can do work if there is
available link and session credit and there is either a message on the queue it
is associated with *or* there is an existing partial transfer (which has not
been remotely settled)
<rgodfrey> When doing work, if there is an existing partial transfer, the unit
of work could be simply to send one more frame of that transfer
<lorenz> I agree
<rgodfrey> you could possibly simply modify sendNextMessage() in some way and
then add some special code into the 1_0 consumer target

> [Java Broker] In AMQP 1.0 session credit should be checked for every Transfer

> Key: QPID-7813
> URL: https://issues.apache.org/jira/browse/QPID-7813
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Lorenz Quack
>
> In AMQP 1.0 session credit is in terms of transfers.
> We currently only check the session credit when deciding to send a message or
> not.
> Instead we should check the session credit upon every Transfer.
> This means that we need to be able to send partial messages (in case the
> session credit is insufficient) and later resume the delivery when more
> session credit becomes available.
