Contributor’s Guide¶

If you’re reading this, you’re probably interested in contributing to Requests. Thank you very much! Open source projects live-and-die based on the support they receive from others, and the fact that you’re even considering contributing to the Requests project is very generous of you.

This document lays out guidelines and advice for contributing to this project. If you’re thinking of contributing, please start by reading this document and getting a feel for how contributing to this project works. If you have any questions, feel free to reach out to either Nate Prewitt, Ian Cordasco, or Seth Michael Larson, the primary maintainers.

The guide is split into sections based on the type of contribution you’re thinking of making, with a section that covers general guidelines for all contributors.

Be Cordial¶

Be cordial or be on your way. —Kenneth Reitz

Requests has one very important rule governing all forms of contribution, including reporting bugs or requesting features. This golden rule is “be cordial or be on your way”.

All contributions are welcome, as long as everyone involved is treated with respect.

Get Early Feedback¶

If you are contributing, do not feel the need to sit on your contribution until it is perfectly polished and complete. It helps everyone involved for you to seek feedback as early as you possibly can. Submitting an early, unfinished version of your contribution for feedback in no way prejudices your chances of getting that contribution accepted, and can save you from putting a lot of work into a contribution that is not suitable for the project.

Contribution Suitability¶

Our project maintainers have the last word on whether or not a contribution is suitable for Requests. All contributions will be considered carefully, but from time to time, contributions will be rejected because they do not suit the current goals or needs of the project.

If your contribution is rejected, don’t despair! As long as you followed these guidelines, you will have a much better chance of getting your next contribution accepted.

Code Contributions¶

Steps for Submitting Code¶

When contributing code, you’ll want to follow this checklist:

Fork the repository on GitHub.
Run the tests to confirm they all pass on your system. If they don’t, you’ll need to investigate why they fail. If you’re unable to diagnose this yourself, raise it as a bug report by following the guidelines in this document: Bug Reports.
Write tests that demonstrate your bug or feature. Ensure that they fail.
Make your change.
Run the entire test suite again, confirming that all tests pass including the ones you just added.
Send a GitHub Pull Request to the main repository’s main branch. GitHub Pull Requests are the expected method of code collaboration on this project.

The following sub-sections go into more detail on some of the points above.

Code Review¶

Contributions will not be merged until they’ve been code reviewed. You should implement any code review feedback unless you strongly object to it. In the event that you object to the code review feedback, you should make your case clearly and calmly. If, after doing so, the feedback is judged to still apply, you must either apply the feedback or withdraw your contribution.

Code Style¶

Requests uses a collection of tools to ensure the code base has a consistent style as it grows. We have these orchestrated using a tool called pre-commit. This can be installed locally and run over your changes prior to opening a PR, and will also be run as part of the CI approval process before a change is merged.

You can find the full list of formatting requirements specified in the .pre-commit-config.yaml at the top level directory of Requests.

New Contributors¶

If you are new or relatively new to Open Source, welcome! Requests aims to be a gentle introduction to the world of Open Source. If you’re concerned about how best to contribute, please consider mailing a maintainer (listed above) and asking for help.

Please also check the Get Early Feedback section.

Documentation Contributions¶

Documentation improvements are always welcome! The documentation files live in the docs/ directory of the codebase. They’re written in reStructuredText, and use Sphinx to generate the full suite of documentation.

When contributing documentation, please do your best to follow the style of the documentation files. This means a soft-limit of 79 characters wide in your text files and a semi-formal, yet friendly and approachable, prose style.

When presenting Python code, use single-quoted strings ('hello' instead of "hello").

Bug Reports¶

Bug reports are hugely important! Before you raise one, though, please check through the GitHub issues, both open and closed, to confirm that the bug hasn’t been reported before. Duplicate bug reports are a huge drain on the time of other contributors, and should be avoided as much as possible.

Feature Requests¶

Requests is in a perpetual feature freeze, only the BDFL can add or approve of new features. The maintainers believe that Requests is a feature-complete piece of software at this time.

One of the most important skills to have while maintaining a largely-used open source project is learning the ability to say “no” to suggested changes, while keeping an open ear and mind.

If you believe there is a feature missing, feel free to raise a feature request, but please do be aware that the overwhelming likelihood is that your feature request will not be accepted.
