Andrew Stitcher commented on PROTON-1174:
-----------------------------------------
[~chug] can you confirm what AMQP lib the receiving app is using here:
As far as I can tell proton-c has a matching bug on receiving an OPEN frame. In
other words it will interpret no channel_max as meaning 0 upon receipt as well
as sending.
> 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
> Assignee: Andrew Stitcher
> Priority: Major
> Labels: codec
> Fix For: proton-c-0.20.0
>
>
> 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.
