A great way to contribute to the project is to send a detailed report when you encounter an issue.
Check that our issue database doesn't already include that problem or suggestion before submitting an issue. If you find a match, you can use the "subscribe" button to get notified on updates. Do not leave random "+1" or "I have this too" comments, as they only clutter the discussion, and don't help resolving it. However, if you have ways to reproduce the issue or have additional information that may help resolving the issue, please leave a comment.
Also include the steps required to reproduce the problem if possible and applicable. This information will help us review and fix your issue faster. When sending lengthy log-files, consider posting them as a gist. Don't forget to remove sensitive data from your logfiles before posting (you can replace those parts with "REDACTED").
If you would like to fix a bug or implement a new feature the best way to do that is via a pull request. For bigger changes and new features it may be a good idea to give EVE's community a heads up on the mailing list or Slack first so that you won't spend too much time implementing something that may be out of scope for the project.
Not sure if that typo is worth a pull request? Found a bug and know how to fix it? Do it! We will appreciate it. We are always thrilled to receive pull requests. We do our best to process them quickly. If your pull request is not accepted on the first try, don't get discouraged!
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.
Commit messages should follow best practices, including explaining the context of the problem and how it was solved, including in caveats or follow up changes required. They should tell the story of the change and provide readers understanding of what led to it.
If you're lost about what this even means, please see How to Write a Git Commit Message for a start.
In practice, the best approach to maintaining a nice commit message is to
leverage a git add -p
and git commit --amend
to formulate a solid
changeset. This allows one to piece together a change, as information becomes
available.
If you squash a series of commits, don't just submit that. Re-write the commit message, as if the series of commits was a single stroke of brilliance.
That said, there is no requirement to have a single commit for a PR, as long as each commit tells the story. For example, if there is a feature that requires a package, it might make sense to have the package in a separate commit then have a subsequent commit that uses it.
Remember, you're telling part of the story with the commit message. Don't make your chapter weird.
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 master without multiple branches mixed into the PR.
Git tip: If your PR no longer merges cleanly, use rebase master
in your
feature branch to update your pull request rather than merge master
.
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.
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.
Any member of the TSC can merge outstanding Pull Requests, provided they pass the required checks configured on the repository and take care of all the community feedback provided.
The EVE project uses CircleCI to verify changes do not negatively impact the style or functionality of the documentation and code. Some of these tests can be run locally to verify your work, prior to pushing them to GitHub.
Specifically, the yetus tests may be run by using make yetus
. The
first run of that rule will cause a Docker image to be built for running
the tests, which can take a long time. The yetus package will be
downloaded into /tmp/yetus
, and the results from testing the tree will
be placed in the /tmp/yetus-out
directory.
NOTE: The yetus tests were added relatively late to the project, so pre-existing issues remain in the tree. As a result, those issues may be flagged by the CI process when making unrelated changes nearby. Those pre-existing issues must be fixed as part of your PR, if they cause the CI tests to fail. Unless directly touched by an existing patch in your branch, these failures should be fixed in additional new patches by appending them to your branch.
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):
