How to Get Your Change Into Ryu
|
|
*******************************
|
|
|
|
Submitting a change
|
|
===================
|
|
|
|
Send patches to ryu-devel@lists.sourceforge.net. Please don't use 'pull
|
|
request' on github. We expect you to send a patch in Linux kernel
|
|
development style. If you are not familiar with it, please read the
|
|
following document:
|
|
|
|
https://www.kernel.org/doc/Documentation/SubmittingPatches
|
|
|
|
Please check your changes with pep8 and run unittests to make sure
|
|
that they don't break the existing features. The following command
|
|
does both for you:
|
|
|
|
fujita@rose:~/git/ryu$ ./run_tests.sh
|
|
|
|
Of course, you are encouraged to add unittests when you add new
|
|
features (it's not a must though).
|
|
|
|
Python version and libraries
|
|
============================
|
|
* Python 2.6+
|
|
As RHEL 6 adopted python 2.6, features only for 2.7+ should be avoided.
|
|
|
|
* standard library + widely used library
|
|
Basically widely used == OpenStack adopted
|
|
As usual there are exceptions. gevents. Or python binding library for other
|
|
component.
|
|
|
|
Coding style guide
|
|
==================
|
|
* pep8
|
|
As python is used, PEP8 is would be hopefully mandatory for
|
|
http://www.python.org/dev/peps/pep-0008/
|
|
|
|
* pylint
|
|
Although pylint is useful for finding bugs, but pylint score not very
|
|
important for now because we're still at early development stage.
|
|
|
|
* Google python style guide is very helpful
|

|
|
|
|
* JSON files
|
|
Ryu source tree has JSON files under ryu/tests/unit/ofproto/json.
|
|
They are used by unit tests. To make patches easier to read,
|
|
they are normalized using tools/normalize_json.py. Please re-run
|
|
the script before committing changes to these JSON files.
