Submitting patches

This repository only accepts commits that are submitted through “Gerrit”, the code-review software. In order to submit a patch through Gerrit, you'll need to do a one-time setup to get things ready.

  1. Create an account on (You can use OAuth for this, no need for yet-another-password.)

  2. From the root of your libapps/ repo, run the command:

     $ curl -Lo `git rev-parse --git-dir`/hooks/commit-msg ; chmod +x `git rev-parse --git-dir`/hooks/commit-msg

    This will copy a commit-msg hook necessary for Gerrit. The hook annotates your commit messages with Change-Id‘s. It’s important to leave these intact, as it's how commits are mapped to code reviews.

Now you're free to start working. Create a branch to hold your changes...

$ git checkout -b local

Then start hacking and commit your changes. When you're ready to submit, push with...

$ git push origin HEAD:refs/for/master

This will push the current branch to Gerrit for review. Once the change has passed review it will be cherry-picked onto the master branch of the official repository.

The output of this command should include a url to Gerrit web page for the review. Add one or more reviewers using the “Add Reviewer” button on that web page.

If the official repository changes, you can fetch the new commits using...

# This command only affects your local repository files, you can run it
# regardless of which branch you're currently on.
$ git fetch

And then re-base any branches with work-in-progress.

$ git checkout local
$ git rebase origin/master

Sometimes this rebase will fail due to merge conflicts which will have to be resolved by hand.
