If you are interested in contributing to PAL, here are some instructions to get you started. Thank you!
- Linux Kernel Coding Style
- Doxygen/Javadoc instead of kernel-doc
- See CODING-STYLE.md
- Keep changes small (especially if you are a new contributor)
- You are responsible for not breaking something with your PR
- Include examples/test code for pull request
- Tag the commit message with
sublib: function:
. The exact format might not always apply so use common sense. - Commit messages must start with (after the tag) a capitalized and short summary (max. 50 chars) written in the imperative, followed by an optional, more detailed explanatory text which is separated from the summary by an empty line.
- Example of good commit summary:
math: p_sqrt: Implement sqrt function
- Example of bad commit summary:
Improve performance
The general guideline is that someone reading only the first line of the commit message should get a good sense of what the patch is doing.
- Before you submit, please ensure that your change did not break anything:
make check
- If it's a bug fix branch, name it XXXX-something where XXXX is the number of the issue.
- If it's a feature branch, create an enhancement issue to announce your intentions, and name it XXXX-something where XXXX is the number of the issue.
- Pull requests descriptions should be as clear as possible and include a reference to all the issues that they address.
- Code review comments may be added to your pull request. Discuss, then make the suggested modifications and push additional commits to your feature branch. Be sure to post a comment after pushing. The new commits will show up in the pull request automatically, but the reviewers will not be notified unless you comment.
- Pull requests must be cleanly rebased ontop of master without multiple branches mixed into the PR.
- Before the pull request is merged, make sure that you squash your commits into
logical units of work using
git rebase -i
andgit push -f
. After every commit the test suite should be passing. Include documentation changes in the same commit so that a revert would remove all traces of the feature or fix.
For standard issues like bugs and documentation errors please fill out an issue ticket
- Check the Parallella forum and Issue Manager for work in progress
- Describe the problem the proposal solves
- Provide a compelling use case
- Post and discuss your proposal on the Parallella forum
- Submit a pull request that modifies the documentation and adding new documentation as necessary
All major code contribution requires a sign-off. The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
