How to contribute

Source: .github/CONTRIBUTING.md

We welcome third-party patches, which are essential for advancing the science and architecture of gaia. But there are a few guidelines that we ask contributors to follow, guidelines that ease the maintainers’ organizational and logistical duties, while encouraging development by others. All contributors agree to abide by the code of conduct.

Getting Started

  • Make sure you have a GitHub account.
  • Open an issue describing your proposed change or work (after making sure one does not already exist).
    • Clearly describe the issue including steps to reproduce when it is a bug.
    • Discuss how your change will affect gaia, and thus whether it’s MAJOR, MINOR, or a PATCH.
    • Interact with the project maintainers to refine/change/prioritize your issue and identify what branch will be targeted (see below).
  • Trivial changes to comments or documentation do not require creating a new issue.

Making Changes

  • Start your work on the correct branch.
    • The active development branch will be titled dev
    • If your change is a PATCH, it will typically be based on the current dev branch; if MINOR, the next minor release branch; if MAJOR, the next major release branch. For example, as of this writing there are branches dev, rc1.2 and rc2.0, corresponding to the PATCH-MINOR-MAJOR start points respectively.
    • We will never accept pull requests to the main branch.
  • Check for unnecessary whitespace with git diff --check before committing.
  • Make sure your commit messages are descriptive but succinct, describing what was changed and why, and reference the relevant issue number. Make commits of logical units.
  • Make sure you have added the necessary tests for your changes. Tests should be included in the root tests directory and are facilitated using pytest which is installed with the development version of gaia. See more info on using pytest here: https://docs.pytest.org/en/7.4.x/contents.html
  • Run all the tests to assure nothing else was accidentally broken.

Submitting Changes

  • Submit a pull request.
  • Your pull request should include one of the following two statements:
    • You own the copyright on the code being contributed, and you hereby grant PNNL unlimited license to use this code in this version or any future version of gaia. You reserve all other rights to the code.
    • Somebody else owns the copyright on the code being contributed (e.g., your employer because you did it as part of your work for them); you are authorized by that owner to grant PNNL an unlimited license to use this code in this version or any future version of gaia, and you hereby do so. All other rights to the code are reserved by the copyright owner.
  • The core team looks at Pull Requests on a regular basis, and will respond as soon as possible.
