I may have found a bug with the new Error_event class you added
recently. I notice that when I set the xid of a flow mod, the xid in an
error event is different. Perhaps its not converted back from network
format? I'm not sure where that code is, but it is being converted to
network format on the way out in pycontext.cc.

Ugh, I have actually been sitting on a patch forever that add support
for xids all the way through Python; I really should nail it down and
commit it. Sorry.
Change send_flow_command() in context.i also.

Hello,
I'm modifying some Nox code so that core.py's
*install_datapath_flow* takes another argument- the xid for the flow
mod request.
def install_datapath_flow(self, dp_id, attrs, idle_timeout,
hard_timeout,
actions, buffer_id=None,
priority=openflow.OFP_DEFAULT_PRIORITY,
inport=None, packet=None, xid=0):
I also changed *send_flow_command*...
def send_flow_command(self, dp_id, command, attrs,
priority=openflow.OFP_DEFAULT_PRIORITY,
add_args=None,
hard_timeout=openflow.OFP_FLOW_PERMANENT,
xid=0):
... and its call
self.ctxt.send_flow_command(dp_id, command, m, idle_timeout,
hard_timeout, oactions,
buffer_id, priority, xid)
I also made the argument changes in *pycontext.hh* and *pycontext.c*.
However, when I run a Nox component that calls that method, I get
the error:
File "./nox/coreapps/pyrt/pycomponent.py", line 589, in
send_flow_command
def send_flow_command(self, *args): return
_pycomponent.PyContext_send_flow_command(self, *args)
TypeError: PyContext_send_flow_command() *takes exactly 9 arguments
(10 given)*
I did recompile the source. *pycomponent.py* seems to be created
after building, so there is some other step I'm missing. I think it
has to do with swig?
Thanks for your help,
Derek
