Contributor Documentation

Contributor Documentation

Contributing to nova gives you the power to help add features, fix bugs, enhance documentation, and increase testing. Contributions of any type are valuable, and part of what keeps the project going. Here are a list of resources to get your started.

Getting Started

Nova Process

The nova community is a large community. We have lots of users, and they all have a lot of expectations around upgrade and backwards compatibility. For example, having a good stable API, with discoverable versions and capabilities is important for maintaining the strong ecosystem around Nova.

Our process is always evolving, just as nova and the community around Nova evolves over time. If there are things that seem strange, or you have ideas on how to improve things, please bring them forward on IRC or the openstack-dev mailing list, so we continue to improve how the nova community operates.

This section looks at the processes and why. The main aim behind all the process is to aid communication between all members of the nova community, while keeping users happy and keeping developers productive.

For Reviewers

  • Release Notes: When we need a release note for a contribution.
  • Code Review Guide for Nova: important cheat sheet for what's important when doing code review in Nova, especially some things that are hard to test for, but need human eyes.
  • Internationalization: what we require for i18n in patches


Because Python is a dynamic language, code that is not testing might not even be python code. All new code needs to be validated somehow.

The Nova API

Because we have many consumers of our API, we're extremely careful about changes done to the API, as the impact can be very wide.

Nova Major Subsystems

Major subsystems in Nova have different needs, some of those are documented here. If you are contributing to one of these please read the subsystem guide before diving in.
