Subject [jira] [Commented] (QPID-7649) [Java Broker] Support AMQP 1.0 Attach with incomplete-unsettled=true
Date Tue, 30 May 2017 10:57:05 GMT

    [ https://issues.apache.org/jira/browse/QPID-7649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16029259#comment-16029259

Keith Wall commented on QPID-7649:
----------------------------------

Currently, the consumer target created by the sending link does not know that it "MUST NOT
send any new deliveries" (2.7.3 - attach), so it will violate the spec and the peer will be
obliged to detach.   We need a way to tell the consumer target not to deliver anything (perhaps
an additional clause ({{ConsumerTarget_1_0#allocateCredit}}) to consider that incomplete-unsettled
flag.    

It is not clear to me if "Note that if this flag is set to true then the endpoints MUST detach
and reattach at least once in order to send new deliveries."  means that the Broker is required
to detach after actioning the unsettled map.

> The AMQP 1.0 spec (2.7.3) allows to send an Attach with an incomplete {{unsettled}} map
together with {{incomplete-unsettled=true}}. This is useful in cases where the unsettled map
is too large to fit in a single frame.
> We currently do not respect this, violating the spec.
