Send patches to [email protected]. Please don't use "Pull Request" on GitHub. We expect you to send patches in "git-format-patch" style.
# "N" means the number of commits to be included
$ git format-patch -s HEAD~N
# To add cover (e.g., [PATCH 0/X]), specify "--cover-letter" option
$ git format-patch -s --cover-letter HEAD~N
# You can send patches by "git send-email" command
$ git send-email --to="[email protected]" *.patchPlease 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.
# Install dependencies of tests
$ pip install -r tools/test-requires
# Execute unit tests and pep8
$ ./run_tests.shOf course, you are encouraged to add unittests when you add new features (it's not a must though).
Python 2.7, 3.4, 3.5:
Ryu supports multiple Python version. CI tests on Travis-CI is running on these versions.
standard library + widely used library:
Basically widely used == OpenStack adopted. As usual there are exceptions. Or python binding library for other component.
pep8:
As python is used, PEP8 is would be hopefully mandatory for https://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. https://www.pylint.org/
Google python style guide is very helpful: http://google.github.io/styleguide/pyguide.html
Guidelines derived from Guido's Recommendations:

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.
