First of all, thank you so much for your help improving the project! We are so happy to have you!
There are opportunities to contribute to Parallax at any level. It doesn't matter if you are just getting started with Rust or are the most weathered expert, we can use your help.
No contribution is too small and all contributions are valued.
This guide will help you get started. Do not let this guide intimidate you. It should be considered a map to help you navigate the process.
Adapted from the tokio contributing guidelines. Thank you tokio team!
The Parallax project adheres to the Rust Code of Conduct. This describes the minimum behavior expected from all contributors. Instances of violations of the Code of Conduct can be reported by contacting the project team at [email protected].
For any issue, there are fundamentally three ways an individual can contribute:
-
By opening the issue for discussion: For instance, if you believe that you have uncovered a bug in Parallax, creating a new issue in the issue tracker is the way to report it.
-
By helping to triage the issue: This can be done by providing supporting details (a test case that demonstrates a bug), providing suggestions on how to address the issue, or ensuring that the issue is tagged correctly.
-
By helping to resolve the issue: Typically this is done either in the form of demonstrating that the issue reported is not a problem after all, or more often, by opening a Pull Request that changes some bit of something in Parallax in a concrete and reviewable manner.
Anybody can participate in any stage of contribution. We urge you to participate in the discussion around bugs and participate in reviewing PRs.
If you have reviewed existing documentation and still have questions or are having problems, you can open an issue asking for help.
In exchange for receiving help, we ask that you contribute back a documentation PR that helps others avoid the problems that you encountered.
When opening a new issue in the Parallax issue tracker, users will be presented with two fields that should be filled in. If you believe that you have uncovered a bug, please fill out this form, following the template to the best of your ability. Do not worry if you cannot answer every detail, just fill in what you can.
The two most important pieces of information we need in order to properly evaluate the report is a description of the behavior you are seeing and a simple test case we can use to recreate the problem on our own. If we cannot recreate the issue, it becomes impossible for us to fix.
In order to rule out the possibility of bugs introduced by userland code, test cases should be limited, as much as possible, to using only Refiney Internals.
See How to create a Minimal, Complete, and Verifiable example.
Once an issue has been opened, it is not uncommon for there to be discussion around it. Some contributors may have differing opinions about the issue, including whether the behavior being seen is a bug or a feature. This discussion is part of the process and should be kept focused, helpful, and professional.
Short, clipped responses—that provide neither additional context nor supporting detail—are not helpful or professional. To many, such responses are simply annoying and unfriendly.
Contributors are encouraged to help one another make forward progress as much as possible, empowering one another to solve issues collaboratively. If you choose to comment on an issue that you feel either is not a problem that needs to be fixed, or if you encounter information in an issue that you feel is incorrect, explain why you feel that way with additional supporting context, and be willing to be convinced that you may be wrong. By doing so, we can often reach the correct outcome much faster.
In the majority of cases, issues are resolved by opening a Pull Request. The process for opening and reviewing a Pull Request is similar to that of opening and triaging issues, but carries with it a necessary review and approval workflow that ensures that the proposed changes meet the minimal quality and functional guidelines of the Parallax project.
Pull Requests are the way concrete changes are made to the code, documentation, and dependencies in the Parallax repository.
Even tiny pull requests (e.g., one character pull request fixing a typo in API documentation) are greatly appreciated. Before making a large change, it is usually a good idea to first open an issue describing the change to solicit feedback and guidance. This will increase the likelihood of the PR getting merged.
If the change being proposed alters code (as opposed to only documentation for example), it is either adding new functionality to Parallax or it is fixing existing, broken functionality. In both of these cases, the pull request should include one or more tests to ensure that Parallax does not regress in the future. There are two ways to write tests: integration tests and documentation tests (Parallax avoids unit tests as much as possible).
It is a recommended best practice to keep your changes as logically grouped as possible within individual commits. There is no limit to the number of commits any single Pull Request may have, and many contributors find it easier to review changes that are split across multiple commits.
That said, if you have a number of commits that are "checkpoints" and don't represent a single logical change, please squash those together.
Note that multiple commits often get squashed when they are landed (see the notes about [commit squashing]).
From within GitHub, opening a new Pull Request will present you with a template that should be filled out. Please try to do your best at filling out the details, but feel free to skip parts if you're not sure what to put.
You will probably get feedback or requests for changes to your Pull Request. This is a big part of the submission process so don't be discouraged! Some contributors may sign off on the Pull Request right away, others may have more detailed comments or feedback. This is a necessary part of the process in order to evaluate whether the changes are correct and necessary.
Any community member can review a PR and you might get conflicting feedback. Keep an eye out for comments from code owners to provide guidance on conflicting feedback.
Once the PR is open, do not rebase the commits. See [Commit Squashing] for more details.
In most cases, do not squash commits that you add to your Pull Request during the review process. When the commits in your Pull Request land, they may be squashed into one commit per logical change. Metadata will be added to the commit message (including links to the Pull Request, links to relevant issues, and the names of the reviewers). The commit history of your Pull Request, however, will stay intact on the Pull Request page.
