Open Stack

I think we need to pick either one or the other. We currently have two places where debugging is documented, the OpenStack wiki and in the Neutron tree

That i need to change the neutron server code to this=>eventlet.monkey_patch() To: eventlet.monkey_patch(os=False, thread=False)
I don't need to do this. But I do need to go into the PyCharm settings under Python Debugger and enable "Gevent compatible debugging".

I have done so, debug seems to run, but when i am trying to initiate commands from the CLI i get this:

gal at ubuntu:~/devstack$ neutron net-list
Connection to neutron failed: Maximum attempts reached

Are you sure you have sourced openrc correctly for the credentials?

(the server seems to run ok...)

Any help is appreciated as i am trying to learn and understand main flows by debugging the code locally.

First I start devstack in offline mode.
    OFFLINE=True ./stack.sh

Once it is running I go to the neutron window in screen.
There I stop neutron-server with ctrl-C, and press up-arrow to view the start command.

To run neutron-server in the PyCharm debugger edit the Run/Debug configuration with the following settings:

Script: /usr/local/bin/neutron-server
Script params: --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini
    # I got this from the screen window where I stopped neutron
Working directory: /opt/stack/neutron

Now restart neutron from PyCharm instead of screen.
