This doc describes the +process to contribute patches to protobuf and the general guidelines we +expect contributors to follow. + +## Before You Start + +We accept patches in the form of github pull requests. If you are new to +github, please read [How to create github pull requests](https://help.github.com/articles/about-pull-requests/) +first. + +### Contributor License Agreements + +Contributions to this project must be accompanied by a Contributor License +Agreement. You (or your employer) retain the copyright to your contribution, +this simply gives us permission to use and redistribute your contributions +as part of the project. + +* If you are an individual writing original source code and you're sure you + own the intellectual property, then you'll need to sign an [individual CLA](https://cla.developers.google.com/about/google-individual?csw=1). +* If you work for a company that wants to allow you to contribute your work, + then you'll need to sign a [corporate CLA](https://cla.developers.google.com/about/google-corporate?csw=1). + +### Coding Style + +This project follows [Google’s Coding Style Guides](https://github.com/google/styleguide). +Before sending out your pull request, please familiarize yourself with the +corresponding style guides and make sure the proposed code change is style +conforming. + +## Contributing Process + +Most pull requests should go to the master branch and the change will be +included in the next major/minor version release (e.g., 3.6.0 release). If you +need to include a bug fix in a patch release (e.g., 3.5.2), make sure it’s +already merged to master, and then create a pull request cherry-picking the +commits from master branch to the release branch (e.g., branch 3.5.x). + +For each pull request, a protobuf team member will be assigned to review the +pull request. For minor cleanups, the pull request may be merged right away +after an initial review. For larger changes, you will likely receive multiple +rounds of comments and it may take some time to complete. We will try to keep +our response time within 7-days but if you don’t get any response in a few +days, feel free to comment on the threads to get our attention. We also expect +you to respond to our comments within a reasonable amount of time. If we don’t +hear from you for 2 weeks or longer, we may close the pull request. You can +still send the pull request again once you have time to work on it. + +Once a pull request is merged, we will take care of the rest and get it into +the final release. + +## Pull Request Guidelines + +* If you are a Googler, it is preferable to first create an internal CL and + have it reviewed and submitted. The code propagation process will deliver the + change to GitHub. +* Create small PRs that are narrowly focused on addressing a single concern. + We often receive PRs that are trying to fix several things at a time, but if + only one fix is considered acceptable, nothing gets merged and both author's + & review's time is wasted. Create more PRs to address different concerns and + everyone will be happy. +* For speculative changes, consider opening an issue and discussing it first. + If you are suggesting a behavioral or API change, make sure you get explicit + support from a protobuf team member before sending us the pull request. +* Provide a good PR description as a record of what change is being made and + why it was made. Link to a GitHub issue if it exists. +* Don't fix code style and formatting unless you are already changing that + line to address an issue. PRs with irrelevant changes won't be merged. If + you do want to fix formatting or style, do that in a separate PR. +* Unless your PR is trivial, you should expect there will be reviewer comments + that you'll need to address before merging. We expect you to be reasonably + responsive to those comments, otherwise the PR will be closed after 2-3 weeks + of inactivity. +* Maintain clean commit history and use meaningful commit messages. PRs with + messy commit history are difficult to review and won't be merged. Use rebase + -i upstream/master to curate your commit history and/or to bring in latest + changes from master (but avoid rebasing in the middle of a code review). +* Keep your PR up to date with upstream/master (if there are merge conflicts, + we can't really merge your change). +* All tests need to be passing before your change can be merged. We recommend + you run tests locally before creating your PR to catch breakages early on. + Ultimately, the green signal will be provided by our testing infrastructure. + The reviewer will help you if there are test failures that seem not related + to the change you are making. -- cgit v1.2.3
