             Summary: [python, ruby] Unable to receive messages when max-frame-size is set to more than 2^20
                 Key: PROTON-1809
                 URL: https://issues.apache.org/jira/browse/PROTON-1809
             Project: Qpid Proton
          Issue Type: Bug
          Components: python-binding, ruby-binding
    Affects Versions: proton-c-0.22.0
         Environment: RHEL 7 x86_64
            Reporter: Radim Kubis
            Assignee: Alan Conway


*Python:*
{code}
  def on_session_init(self, event):
     event.transport._set_max_frame_size(VALUE)
{code} 

I noticed that the receiver is not able to receive messages when the value for max-frame-size is larger than 2^20 (1048576) bytes (remote_max_frame_size is 4294967295). I'm not really sure if that is expected. This may be reproduced when adding the code above ie.: to simple_recv.py.

Note: This is not a good use case as setting the max-frame-size in on_session_init is really too late. But given that it is too late to set the max-frame-size, I would expect it won't have any effect on the client.

 

*Ruby:*

Receiver is stuck.
