Neutron Style Commandments
=======================
- Step 1: Read the OpenStack Style Commandments
http://docs.openstack.org/developer/hacking/
- Step 2: Read on
Neutron Specific Commandments
--------------------------
- [N320] Validate that LOG messages, except debug ones, have translations
Creating Unit Tests
-------------------
For every new feature, unit tests should be created that both test and
(implicitly) document the usage of said feature. If submitting a patch for a
bug that had no unit test, a new passing unit test should be added. If a
submitted bug fix does have a unit test, be sure to add a new one that fails
without the patch and passes with the patch.
All unittest classes must ultimately inherit from testtools.TestCase. In the
Neutron test suite, this should be done by inheriting from
neutron.tests.base.BaseTestCase.
All setUp and tearDown methods must upcall using the super() method.
tearDown methods should be avoided and addCleanup calls should be preferred.
Never manually create tempfiles. Always use the tempfile fixtures from
the fixture library to ensure that they are cleaned up.

Testing Neutron
=============================================================
Overview
--------
The unit tests are meant to cover as much code as possible and should
be executed without the service running. They are designed to test
the various pieces of the neutron tree to make sure any new changes
don't break existing functionality.
The functional tests are intended to validate actual system
interaction. Mocks should be used sparingly, if at all. Care
should be taken to ensure that existing system resources are not
modified and that resources created in tests are properly cleaned
up.
Development process
-------------------
It is expected that any new changes that are proposed for merge
come with tests for that feature or code area. Ideally any bugs
fixes that are submitted also have tests to prove that they stay
fixed! In addition, before proposing for merge, all of the
current tests should be passing.
Virtual environments
~~~~~~~~~~~~~~~~~~~~
Testing OpenStack projects, including Neutron, is made easier with `DevStack <https://github.com/openstack-dev/devstack>`_.
Create a machine (such as a VM or Vagrant box) running a distribution supported
by DevStack and install DevStack there. For example, there is a Vagrant script
for DevStack at https://github.com/bcwaldon/vagrant_devstack.
.. note::
If you prefer not to use DevStack, you can still check out source code on your local
machine and develop from there.
Running unit tests
------------------
There are three mechanisms for running tests: run_tests.sh, tox,
and nose. Before submitting a patch for review you should always
ensure all test pass; a tox run is triggered by the jenkins gate
executed on gerrit for each patch pushed for review.
With these mechanisms you can either run the tests in the standard
environment or create a virtual environment to run them in.
By default after running all of the tests, any pep8 errors
found in the tree will be reported.
With `run_tests.sh`
~~~~~~~~~~~~~~~~~~~
You can use the `run_tests.sh` script in the root source directory to execute
tests in a virtualenv::
./run_tests -V
With `nose`
~~~~~~~~~~~
You can use `nose`_ to run individual tests, as well as use for debugging
portions of your code::
source .venv/bin/activate
pip install nose
nosetests
There are disadvantages to running Nose - the tests are run sequentially, so
race condition bugs will not be triggered, and the full test suite will
take significantly longer than tox & testr. The upside is that testr has
some rough edges when it comes to diagnosing errors and failures, and there is
no easy way to set a breakpoint in the Neutron code, and enter an
interactive debugging session while using testr.
.. _nose: https://nose.readthedocs.org/en/latest/index.html
With `tox`
~~~~~~~~~~
Neutron, like other OpenStack projects, uses `tox`_ for managing the virtual
environments for running test cases. It uses `Testr`_ for managing the running
of the test cases.
Tox handles the creation of a series of `virtualenvs`_ that target specific
versions of Python (2.6, 2.7, 3.3, etc).
Testr handles the parallel execution of series of test cases as well as
the tracking of long-running tests and other things.
Running unit tests is as easy as executing this in the root directory of the
Neutron source code::
tox
For more information on the standard Tox-based test infrastructure used by
OpenStack and how to do some common test/debugging procedures with Testr,
see this wiki page:
https://wiki.openstack.org/wiki/Testr
.. _Testr: https://wiki.openstack.org/wiki/Testr
.. _tox: http://tox.readthedocs.org/en/latest/
.. _virtualenvs: https://pypi.python.org/pypi/virtualenv
Running individual tests
~~~~~~~~~~~~~~~~~~~~~~~~
For running individual test modules or cases, you just need to pass
the dot-separated path to the module you want as an argument to it.
For executing a specific test case, specify the name of the test case
class separating it from the module path with a colon.
For example, the following would run only the JSONV2TestCase tests from
neutron/tests/unit/test_api_v2.py::
$ ./run_tests.sh neutron.tests.unit.test_api_v2:JSONV2TestCase
or::
$ ./tox neutron.tests.unit.test_api_v2:JSONV2TestCase
Adding more tests
~~~~~~~~~~~~~~~~~
Neutron has a fast growing code base and there is plenty of areas that
need to be covered by unit and functional tests.
To get a grasp of the areas where tests are needed, you can check
current coverage by running::
$ ./run_tests.sh -c
Debugging
---------
By default, calls to pdb.set_trace() will be ignored when tests
are run. For pdb statements to work, invoke run_tests as follows::
$ ./run_tests.sh -d [test module path]
It's possible to debug tests in a tox environment::
$ tox -e venv -- python -m testtools.run [test module path]
Tox-created virtual environments (venv's) can also be activated
after a tox run and reused for debugging::
$ tox -e venv
$ . .tox/venv/bin/activate
$ python -m testtools.run [test module path]
Tox packages and installs the neutron source tree in a given venv
on every invocation, but if modifications need to be made between
invocation (e.g. adding more pdb statements), it is recommended
that the source tree be installed in the venv in editable mode::
# run this only after activating the venv
$ pip install --editable .
Editable mode ensures that changes made to the source tree are
automatically reflected in the venv, and that such changes are not
overwritten during the next tox run.
Post-mortem debugging
~~~~~~~~~~~~~~~~~~~~~
Setting OS_POST_MORTEM_DEBUG=1 in the shell environment will ensure
that pdb.post_mortem() will be invoked on test failure::
$ OS_POST_MORTEM_DEBUG=1 ./run_tests.sh -d [test module path]

API Extensions
==============
API extensions is the standard way of introducing new functionality
to the Neutron project, it allows plugins to
determine if they wish to support the functionality or not.
Examples
========
The easiest way to demonstrate how an API extension is written, is
by studying an existing API extension and explaining the different layers.

Neutron WSGI/HTTP API layer
===========================
This section will cover the internals of Neutron's HTTP API, and the classes
in Neutron that can be used to create Extensions to the Neutron API.
Python web applications interface with webservers through the Python Web
Server Gateway Interface (WSGI) - defined in `PEP 333 <http://legacy.python.org/dev/peps/pep-0333/>`_
Startup
-------
Neutron's WSGI server is started from the `server module <http://git.openstack.org/cgit/openstack/neutron/tree/neutron/server/__init__.py>`_
and the entry point `serve_wsgi` is called to build an instance of the
`NeutronApiService`_, which is then returned to the server module,
which spawns a `Eventlet`_ `GreenPool`_ that will run the WSGI
application and respond to requests from clients.
.. _NeutronApiService: http://git.openstack.org/cgit/openstack/neutron/tree/neutron/service.py
.. _Eventlet: http://eventlet.net/
.. _GreenPool: http://eventlet.net/doc/modules/greenpool.html
WSGI Application
----------------
During the building of the NeutronApiService, the `_run_wsgi` function
creates a WSGI application using the `load_paste_app` function inside
`config.py`_ - which parses `api-paste.ini`_ - in order to create a WSGI app
using `Paste`_'s `deploy`_.
The api-paste.ini file defines the WSGI applications and routes - using the
`Paste INI file format`_.
The INI file directs paste to instantiate the `APIRouter`_ class of
Neutron, which contains several methods that map Neutron resources (such as
Ports, Networks, Subnets) to URLs, and the controller for each resource.
.. _config.py: http://git.openstack.org/cgit/openstack/neutron/tree/neutron/common/config.py
.. _api-paste.ini: http://git.openstack.org/cgit/openstack/neutron/tree/etc/api-paste.ini
.. _APIRouter: http://git.openstack.org/cgit/openstack/neutron/tree/neutron/api/v2/router.py
.. _Paste: http://pythonpaste.org/
.. _Deploy: http://pythonpaste.org/deploy/
.. _Paste INI file format: http://pythonpaste.org/deploy/#applications

Setting Up a Development Environment
====================================
This page describes how to setup a working Python development
environment that can be used in developing Neutron on Ubuntu, Fedora or
Mac OS X. These instructions assume you're already familiar with
Git and Gerrit, which is a code repository mirror and code review toolset
, however if you aren't please see `this Git tutorial`_ for an introduction
to using Git and `this wiki page`_ for a tutorial on using Gerrit and Git for
code contribution to Openstack projects.
.. _this Git tutorial: http://git-scm.com/book/en/Getting-Started
.. _this wiki page: https://wiki.openstack.org/wiki/Gerrit_Workflow
Following these instructions will allow you to run the Neutron unit
tests. If you want to be able to run Neutron in a full OpenStack environment,
you can use the excellent `DevStack`_ project to do so. There is a wiki page
that describes `setting up Neutron using DevStack`_.
.. _DevStack: https://github.com/openstack-dev/devstack
.. _setting up Neutron using Devstack: https://wiki.openstack.org/wiki/NeutronDevstack
Getting the code
----------------

Finding the router in ip/ipconfig
---------------------------------
* http://docs.openstack.org/admin-guide-cloud/content/ch_networking.html
The neutron-l3-agent uses the Linux IP stack and iptables to perform L3 forwarding and NAT.
In order to support multiple routers with potentially overlapping IP addresses, neutron-l3-agent
defaults to using Linux network namespaces to provide isolated forwarding contexts. As a result,
the IP addresses of routers will not be visible simply by running "ip addr list" or "ifconfig" on
the node. Similarly, you will not be able to directly ping fixed IPs.
To do either of these things, you must run the command within a particular router's network
namespace. The namespace will have the name "qrouter-<UUID of the router>.
