I have a situation where a receiver (proton python's simple_recv.py) is receiving a multi-frame transfer from a Dispatch Router. The settled flag is false on all the transfer frames except on the last frame which has settled=true as seen here -
https://pastebin.com/37SYrg92 Proton considers the delivery as unsettled and as a result some of the Dispatch router tests are failing like this one - https://github.com/apache/qpid-dispatch/blob/master/tests/system_tests_one_router.py#L1097 The AMQP 1.0 spec says the following about the settled flag on transfers - settled - If not set on the first (or only) transfer for a (multi-transfer) delivery, then the settled flag MUST be interpreted as being false. For subsequent transfers in a multi-transfer delivery if the settled flag is left unset then it MUST be interpreted as true if and only if the value of the settled flag on any of the preceding transfers was true; if no preceding transfer was sent with settled being true then the value when unset MUST be taken as false. I am not sure the above applies to my situation. My question is, is this delivery settled? It logically looks settled to me since the last frame did have settled=true. Thoughts? Thanks, Ganesh.
