[jira] [Created] (PROTON-1174) Proton C encodes Open.channel-max 0 as a null and not as a uint.

Chuck Rolke created PROTON-1174:
-----------------------------------

             Summary: Proton C encodes Open.channel-max 0 as a null and not as a uint.
                 Key: PROTON-1174
                 URL: https://issues.apache.org/jira/browse/PROTON-1174
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.12.0
            Reporter: Chuck Rolke


A connection Open frame is created with the intent of limiting the peer to exactly one link.
{noformat}
  pn_transport_set_channel_max(pn_trans, 0);
{noformat}

Proton encodes the frame with a null 0x40 going over the wire in the channel-max slot.

A receiving application treats the value as 'default' and uses the spec default value of 65535. If the receiving application had received a 0x43 (types:encoding uint:uint0) it would have used the intended channel max of 0.
