Contributions to edx-platform are very welcome, and strongly encouraged! We've put together some documentation that describes our contribution process, but here's a step-by-step guide that should help you get started.
Got an idea for how to improve the codebase? Fantastic, we'd love to hear about it! Before you dive in and spend a lot of time and effort making a pull request, it's a good idea to discuss your idea with other interested developers. You may get some valuable feedback that changes how you think about your idea, or you may find other developers who have the same idea and want to work together.
For real-time conversation, we use IRC: we all hang out in the #edx-code channel on Freenode. Come join us! The channel tends to be most active Monday through Friday between 13:00 and 21:00 UTC (9am to 5pm US Eastern time), but interesting conversations can happen at any time.
For asynchronous conversation, we have several mailing lists on Google Groups:
- openedx-ops: everything related to running Open edX. This includes installation issues, server management, cost analysis, and so on.
- openedx-translation: everything related to translating Open edX into other languages. This includes volunteer translators, our internationalization infrastructure, issues related to Transifex, and so on.
- openedx-analytics: everything related to analytics in Open edX.
- edx-code: everything related to the code in Open edX. This includes feature requests, idea proposals, refactorings, and so on.
Before edX can accept any code contributions from you, you'll need to sign the individual contributor agreement and send it in. This confirms that you have the authority to contribute the code in the pull request and ensures that edX can relicense it.
You should print out the agreement and sign it. Then scan (or photograph) the signed agreement and email it to the email address indicated on the agreement. Alternatively, you're also free to physically mail the agreement to the street address on the agreement. Once we have your agreement in hand, we can begin reviewing and merging your work.
You'll also need to add yourself to the AUTHORS file when you submit your first pull request. You should add your full name as well as the email address associated with your Github account. Please update AUTHORS in an individual commit, distinct from other changes in the pull request (it's OK for a pull request to contain multiple commits, including a commit to AUTHORS). Alternatively, you can open up a separate PR just to have your name added to the AUTHORS file, and link that PR to the PR with your changes.
Github has some great documentation on how to fork a git repository. Once you've done that, make your changes and send us a pull request! Be sure to include a detailed description for your pull request, so that a community manager can understand what change you're making, why you're making it, how it should work now, and how you can test that it's working correctly.
Our contributor documentation includes a long list of requirements that pull requests must meet in order to be reviewed by a core committer. These requirements include things like documentation and passing tests: see the contributor documentation page for the full list.
A community manager will read the description of your pull request. If the description is understandable, the community manager will send the pull request to a product owner. The product owner will evaluate if the pull request is a good idea for Open edX, and if not, your pull request will be rejected. This is another good reason why you should discuss your ideas with other members of the community before working on a pull request!
If your pull request meets the requirements listed in the contributor documentation, and it hasn't been rejected by a product owner, then it will be scheduled for code review by one or more core committers. This process sometimes takes awhile: currently, all core committers on the project are employees of edX, and they have to balance their time between code review and new development. Please also read our code ownership page, which lists areas and concepts in the codebase that are "owned" by certain developers. If your change touches one of these areas or concepts, that developer should be one of the reviewers.
Once the code review process has started, please be responsive to comments on the pull request, so we can keep the review process moving forward. If you are unable to respond for a few days, that's fine, but please add a comment informing us of that -- otherwise, it looks like you're abandoning your work!
Once the core committers are satisfied that your pull request is ready to go, one of them will merge it for you. Your code will end up on the edX production servers in the next release, which usually which happens every week. Congrats!
By opening up a pull request, we expect the following things:
- You've read and understand the instructions in this contributing file and the contribution process documentation.
- You are ready to engage with the edX community. Engaging means you will be prompt in following up with review comments and critiques. Do not open up a pull request right before a vacation or heavy workload that will render you unable to participate in the review process.
- If you have questions, you will ask them by either commenting on the pull request or asking us in IRC or on the mailing list.
- If you do not respond to comments on your pull request within 7 days, we will close it. You are welcome to re-open it when you are ready to engage.
- Within a week of opening up a pull request, one of our community managers will triage it, starting the documented contribution process. (Please give us a little extra time if you open the PR on a weekend or around a US holiday! We may take a little longer getting to it.)
- We promise to engage in an active dialogue with you from the time we begin reviewing until either the PR is merged (by a core committer), or we decide that, for whatever reason, it should be closed.
- Once we have determined through visual review that your code is not malicious, we will run a Jenkins build on your branch.
