"Cheated" is a bit harsh. :-)

Yeah, I wanted to use the handle owned by the service, but couldn't get to
it. I thought asking for a connection without specifying that it had to be
a new one would be a work-around. I was surprised that the manager object
wasn't given access to the service so it could subscribe to messages, but I
guess that's supposed to be the Service's job.

It does give us access to other parts of the framework like logging. And we
may eventually find a need to communicate with the service via RPC.

Actually, the Service class is supposed to handle the AMQP (or whatever
backend) connection itself and bind it to a set of topics. But it uses
the nova.rpc.impl_kombu.Connection class that uses ProxyCallback and
that one obviously fails to decode notification. This is why I say I
failed to the Service class.

You cheated since you opened another AMQP connection in your Manager
class, rendering the connection from the Service class useless. I wish
we could access the connection from the Service from the Manager so we
can reuse it at least, but that does not seem possible neither.

On the other hand, even if it's not the cleanest way to do things, I
kind of like using the Service class so I'll probably grab your code
anyway. :-)

Thanks Doug,

I'm not sure what you mean. I was able to use nova.service to create a
"metering" server and a simple manager that subscribes to the notification
events. See https://github.com/dhellmann/metering-prototype (metering-test
is the main program and testmanager.py is the manager class). I borrowed
your Connection code.

There is no technical difference (to my knowledge ;-). Only 
review.stackforge.org  is for projects that are 
not incubated yet.

Re: [Openstack] [Metering] Bootstrapping, first counter implementation

2012-05-09 Thread heut2008 
stackForge is a Gerrit review and Jenkins CI setup similar to that of
the main OpenStack project but for use with projects that are not
under the main OpenStack umbrella.

Any project can be added to StackForge as long as it is related to
OpenStack in some way.

[Openstack] [Metering] Bootstrapping, first counter implementation

2012-05-09 Thread Julien Danjou 
Hi there,

I've added a first script that's able to connect to the AMQP
notification queue using Nova RPC module. Later it will be able to treat
them when we'll know what to do with them.

  https://review.stackforge.org/#/c/26/
  https://review.stackforge.org/#/c/27/
  https://review.stackforge.org/#/c/28/

I wish I could use nova.service.Service, but the code is too RPC
oriented so that it can't grab notification from the notifier, so for
now the daemon is rather simple.
