Ken Giusti commented on PROTON-961:
-----------------------------------
Let me retract that - this isn't the correct fix.
I tried hacking a copy of messenger to set the max-frame on its connections to
128 bytes. A few of the unit tests start failing with that setting, so I
applied Gordon's fix above. His fix prevents a few of the failures, but
proton_tests.messenger.MessengerTest.testSendReceive1M fails.
Turns out even with that patch Messenger will hang for messages >= 1meg. This
is caused by the incoming-window closing on the receiver. Since the transfers
are partial, messenger never calls pn_link_advance or pn_link_recv, which
replenishes the incoming window.
> messenger doesn't handle multi-frame transfers
