Re: [nox-dev] "ERR:Application 'python' description not found" when running latest NOX

Ah.  Try running nox from its directory.  cd src ; ./nox_core -i ptcp:6634 -v

Hi Stephen,

To test that your NOX compilation is okay with C/C++, run

./nox_core -v -i ptcp:6633 switch

That should do switching fine.  I will let the folks familiar with
Python comment on the problem.

Re: [nox-dev] "ERR:Application 'python' description not found" when running latest NOX

2010-12-17 Thread Stephen Wong

Hi,

I tried running with --with-python=no and the result of that runs (and 
connects to the switch). But that nox_core piece contains no application:

linux-ojon:/home/openflow/nox/nox-no-python/build # src/nox_core -v -i
ptcp:6364 packetdump
1|nox|INFO:Starting nox_core
(/home/openflow/nox/nox-no-python/build/src/.libs/nox_core)
2|nox|DBG:Application installation report:
3|nox|DBG:built-in DSO deployer:
   Current state: INSTALLED
   Required state: INSTALLED
   Dependencies:

4|nox|DBG:built-in event dispatcher:
   Current state: INSTALLED
   Required state: INSTALLED
   Dependencies:

5|nox|ERR:Application 'packetdump' description not found.

Are all the apps dependent on python to run? This is on SUSE (with the 
recommended addition of all the packages including python-devel python-twisted 
and python-curses) - is it possible whatever Python version is being used for 
NOX no longer works with SUSE?

Thanks,
- Stephen

Re: [nox-dev] Help modifying some Nox code for the first time

2010-12-17 Thread James "Murphy" McCauley

This isn't just with the Error_event event -- it just behaves the same
as all the other Python events that currently keep the xid information,
and also the same as the C++ API which does not byte-swap header fields.
I agree it's probably not the most *desirable* behavior, but it is
*consistent* (for some values of "consistent" anyway).

So I think the easy thing to do is for you to probably NOT convert to
network order in your new pycontext code, and leave it up to "the user"
to do it (or not -- since they're opaque, it generally shouldn't matter
if they do it or not as long as they're consistent).  The user may just
be you in this case, in which case do whatever you want. :)

It's altogether possible that I actually do conversion on all
Python-side xids in my as-yet-uncommitted xid patch, but I don't
remember.  I don't immediately see a reason why it would be problematic.
(Of the code currently in the repo, this is at least the event
converters in pyrt.cc, though it may pop up in a few other places too.)

Re: [nox-dev] Help modifying some Nox code for the first time

2010-12-17 Thread Derek Cormier

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.

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,
