This page contains information about reporting issues as well as some tips and guidelines useful to experienced open source contributors. Make sure you read the contribution guideline before you start participating.
A great way to contribute to the project is to send a detailed report when you encounter an issue. We always appreciate a well-written, thorough bug report, and will thank you for it!
Check that the issue database doesn't already include that problem or suggestion before submitting an issue. If you find a match, add a quick "+1" or "I have this problem too." Doing this helps prioritize the most common problems and requests.
When reporting issues, please include your host OS and compiler vendor and version. Please also include the steps required to reproduce the problem if possible and applicable.
This section gives the experienced contributor some tips and guidelines.
Fork the repository and make changes on your fork in a feature branch:
- 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.
Submit unit tests for your changes.
Update the documentation when creating or modifying features. Test your documentation changes for clarity, concision, and correctness.
Pull request descriptions should be as clear as possible and include a reference to all the issues that they address.
Commit messages must start with 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.
Code review comments may be added to your pull request. Discuss, then make the suggested modifications and push additional commits to your feature branch. Post a comment after pushing. New commits show up in the pull request automatically, but the reviewers are notified only when you comment.
Pull requests must be cleanly rebased on top of development without multiple branches mixed into the PR.
Git tip: If your PR no longer merges cleanly, use rebase development in your
feature branch to update your pull request rather than merge development.
Before you make a pull request, squash your commits into logical units of work
using git rebase -i and git push -f. A logical unit of work is a consistent
set of patches that should be reviewed together: for example, upgrading the
version of a vendored dependency and taking advantage of its now available new
feature constitute two separate units of work. Implementing a new function and
calling it in another file constitute a single logical unit of work. The very
high majority of submissions should have a single commit, so if in doubt: squash
down to one.
After every commit, make sure the test suite passes. Include documentation changes in the same pull request so that a revert would remove all traces of the feature or fix.
Include an issue reference like Closes #XXXX or Fixes #XXXX in commits that
close an issue. Including references automatically closes the issue on a merge.
If your change is large enough to warrant a copyright statement, add yourself
to the COPYRIGHT file, using the same style as the existing entries.
The sign-off is a simple line at the end of the explanation for the patch. Your signature certifies that you wrote the patch 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):
