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:
http://lxr.linux.no/source/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 http://google-styleguide.googlecode.com/svn/trunk/pyguide.html
