Want to contribute? Great! First, read this page (including the small print at the end).
Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance that you‘ll tell us if you know that your code infringes on other people’s patents. You don‘t have to sign the CLA until after you’ve submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase. Before you start working on a larger contribution, you should get in touch with us first via email with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.
All submissions, including submissions by project members, require review. We use Gerrit for this purpose.
If you have not done so on this machine, you will need to set up a password for Gerrit. Sign in with a Google account, visit this link, and click the “Generate Password” link in the top right. You will also need to prepare your checkout to add Change-Ids on commit. Run:
curl -Lo .git/hooks/commit-msg https://roughtime-review.googlesource.com/tools/hooks/commit-msg chmod u+x .git/hooks/commit-msg
To upload a change, push it to the special
git push origin HEAD:refs/for/master
The output will then give you a link to the change. Add
firstname.lastname@example.org as reviewers.
Pushing a commit with the same Change-Id as an existing change will upload a new version of it. (Use the
git rebase or
git commit --amend commands.)
For more detailed instructions, see the Gerrit User Guide.
Contributions made by corporations are covered by a different agreement than the one above, the Software Grant and Corporate Contributor License Agreement.
