What is a committer?
Technically, a committer is someone who has write access to the Chromium SVN repository or the Chromium OS Git repository. A committer can submit his or her own patches or patches from others.
This privilege is granted with some expectation of responsibility: committers are people who care about the Chromium projects and want to help them meet their goals. A committer is not just someone who can make changes, but someone who has demonstrated his or her ability to collaborate with the team, get the most knowledgeable people to review code, contribute high-quality code, and follow through to fix issues (in code or tests).
A committer is a contributor to the Chromium projects' success and a citizen helping the projects succeed. See Committer's responsibility.
Becoming a committer
In a nutshell, contribute 10-20 non-trivial patches and get at least three different people to review them (you'll need three people to support you). Then ask someone to nominate you. You're basically demonstrating your
- commitment to the project (10+ good patches requires a lot of your valuable time),
- ability to collaborate with the team,
- understanding of how the team works (policies, processes for testing and code review, etc),
- understanding of the projects' code base and coding style, and
- ability to write good code (last but certainly not least)
A current committer nominates you by sending email to email@example.com containing:
Two other committers need to second your nomination. If no one objects in 5 working days (U.S.), you're a committer. If anyone objects or wants more information, the committers discuss and usually come to a consensus (within the 5 working days). If issues can't be resolved, there's a vote among current committers.
- your first and last name
- your email address. You can also ask to get an @chromium.org email address at this time, if you don't already have one.
- an explanation of why you should be a committer,
- embedded list of links to revisions (about top 10) containing your patches
That's it! There is no further action you need to take on your part. The committers will get back to you once they make a decision.
In the worst case, this can drag out for two weeks. Keep writing patches! Even in the rare cases where a nomination fails, the objection is usually something easy to address like "more patches" or "not enough people are familiar with this person's work."
Once you get approval from the existing committers, we'll send you instructions for write access to SVN or Git. You'll also be added to firstname.lastname@example.org.

Try job access
If you are contributing patches but not (yet) a committer, you may wish to have be able to run jobs on the try servers directly rather than asking a committer or reviewer to do so for you. To get access:
If you have an @chromium.org email address and wish to use it for your account:
If you do not have an @chromium.org email address, or wish to use a different email address;
- Ask someone you're working with (a frequent reviewer, for example) to send email to email@example.com nominating you for tryjob access.
- You must provide an email address and at least a brief explanation of why you'd like access. You can also ask for an @chromium.org address at this time.
- It is helpful to provide a name and company affiliation (if any) as well.
- It is very helpful to have already had some patches landed, but is not absolutely necessary.
If no one objects within two (U.S.) working days, you will be approved for access. It may take an additional few days for the grant to propagate to all of the systems (e.g., Rietveld) and for you to be notified that you're all set..
Maintaining committer status
You don't really need to do much to maintain committer status: just keep being awesome and helping the Chromium projects!
A community of committers working together to move the Chromium projects forward is essential to creating successful projects that are rewarding to work on. If there are problems or disagreements within the community, they can usually be solved through open discussion and debate.
In the unhappy event that a committer continues to disregard good citizenship (or actively disrupts the project), we may need to revoke that person's status. The process is the same as for nominating a new committer: someone suggests the revocation with a good reason, two people second the motion, and a vote may be called if consensus cannot be reached. I hope that's simple enough, and that we never have to test it in practice.
