Description
Rollback with python proton client does not happen if I settle the message (accept it) before doing the rollback. The message will not be redelivered if I try to receive it again afterwards.
I looked at AMQP standard and honestly I do not understand this section about this http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transactions-v1.0-os.html#doc-idp145616. When attempted with qpid-jms, the message will be redelivered, even if I called Message#acknowledge on it.
Workaround is not to settle (not to call self.accept(message) in the python client.
PN_TRACE_FRM looks like this
