Contributing to ruby-git

Thank you for your interest in contributing to the ruby-git project.

This document gives the guidelines for contributing to the ruby-git project. These guidelines may not fit every situation. When contributing use your best judgement.

Propose changes to these guidelines with a pull request.

How to contribute

You can contribute in two ways:

  1. Report an issue or make a feature request
  2. Submit a code or documentation change

How to report an issue or make a feature request

ruby-git utilizes GitHub Issues for issue tracking and feature requests.

Report an issue or feature request by creating a ruby-git Github issue. Fill in the template to describe the issue or feature request the best you can.

How to submit a code or documentation change

There is three step process for code or documentation changes:

  1. Commit your changes to a fork of ruby-git
  2. Create a pull request
  3. Get your pull request reviewed

Commit changes to a fork of ruby-git

Make your changes in a fork of the ruby-git repository.

Each commit must include a DCO sign-off by adding the line Signed-off-by: Name <email> to the end of the commit message.

Create a pull request

See this article if you are not familiar with GitHub Pull Requests.

Follow the instructions in the pull request template.

Get your pull request reviewed

Code review takes place in a GitHub pull request using the the Github pull request review feature.

Once your pull request is ready for review, request a review from at least one maintainer and any number of other contributors.

During the review process, you may need to make additional commits which would need to be squashed. It may also be necessary to rebase to master again if other changes are merged before your PR.

At least one approval is required from a project maintainer before your pull request can be merged. The maintainer is responsible for ensuring that the pull request meets the project's coding standards.

Coding standards

In order to ensure high quality, all pull requests must meet these requirements:

1 PR = 1 Commit

  • All commits for a PR must be squashed into one commit
  • To avoid an extra merge commit, the PR must be able to be merged as a fast forward merge
  • The easiest way to ensure a fast forward merge is to rebase your local branch to the ruby-git master branch

Unit tests

  • All changes must be accompanied by new or modified unit tests
  • The entire test suite must pass when bundle exec rake test is run from the project's local working copy

Continuous Integration

  • All tests must pass in the project's Travis CI build before the pull request will be merged

Documentation

  • New and updated public methods must have YARD documentation added to them
  • New and updated public facing features should be documented in the project's README.md

Licensing sign-off

  • Each commit must contain the DCO sign-off in the form: Signed-off-by: Name <email>

Licensing

ruby-git uses the MIT license as declared in the LICENSE file.

Licensing is very important to open source projects. It helps ensure the software continues to be available under the terms that the author desired.

Developer Certificate of Origin (DCO)

This project requires that authors have permission to submit their contributions under the MIT license. To make a good faith effort to ensure this, ruby-git requires the Developer Certificate of Origin (DCO) process be followed.

This process requires that each commit include a Signed-off-by line that indicates the author accepts the DCO. Here is an example DCO sign-off line:

Signed-off-by: John Doe <[email protected]>

The full text of the DCO version 1.1 is below or at http://developercertificate.org/.

Developer's Certificate of Origin 1.1

By making a contribution to this project, I certify that:

(a) The contribution was created in whole or in part by me and I
    have the right to submit it under the open source license
    indicated in the file; or

(b) The contribution is based upon previous work that, to the
    best of my knowledge, is covered under an appropriate open
    source license and I have the right under that license to
    submit that work with modifications, whether created in whole
    or in part by me, under the same open source license (unless
    I am permitted to submit under a different license), as
    Indicated in the file; or

(c) The contribution was provided directly to me by some other
    person who certified (a), (b) or (c) and I have not modified
    it.

(d) I understand and agree that this project and the contribution
    are public and that a record of the contribution (including
    all personal information I submit with it, including my
    sign-off) is maintained indefinitely and may be redistributed
    consistent with this project or the open source license(s)
    involved.
