Auto-close review requests when pushing commits

Happy new year, everyone! Hope your holidays were fun and relaxing, with great company and wonderful memories. Mine certainly was, and now I’m back with some more tips and tricks to help you get the most out of Review Board and RBCommons.

Last time, we discussed some tips for getting the most out of your Review Board dashboard. This time, let’s talk about how to keep your dashboard clean by automatically closing review requests when pushing changes.

Introducing the post-commit hook

Post-commit hooks are a feature supported by many types of repositories and code hosting services. They allow you to execute custom code when pushing a commit, which is useful for kicking off a build, updating a website, or, in our case, closing a review request.

For self-hosted repositories, this is usually a script that you drop in a directory. This script can talk to Review Board through the RBTools API.

For repositories hosted on services like GitHub or Bitbucket  these are often set up as URLs that the service can POST to. Review Board 2.0+ have some convenient URLs just for this purpose. We’ll talk about these first.

Configuring auto-close for GitHub and Bitbucket

If you’re running Review Board 2.0.7 or higher, we’ve made it very easy to get set up. Simply log into your administration UI and click Repositories. You should see a [Hooks] link beside any GitHub or Bitbucket repositories. Click it, and you’ll get exact instructions on how to get set up.

Do this for every repository you care about. Then, whenever you’re going to push a commit, make sure it has this line in the commit message:

Reviewed at <review request url>

Where, of course, the <review request url> is the full URL to the review request page. The hook will see that line, and close the matching review request for you, complete with information on the commit ID and the branch it landed on.

The upcoming RBTools 0.7 release will make it very easy to include this automatically with a couple new commands. We’ll cover these in a new post once that release is out.

One important caveat: These services need to be able to talk to your server. That means if you’re behind a firewall, you must grant access to these services and forward a port. If you’re on RBCommons, this won’t be a problem, though. And if you’re a GitHub user, look into using GitHub Enterprise with Power Pack for Review Board  for a much more secure code hosting solution.

Configuring auto-close for custom Git repositories

Custom repositories are a bit trickier, because you need a custom script for your setup.

If you’re running Git, we have a script just for you! All you have to do is fill in some of the details in the script, rename it to post-receive, and drop it into your official Git repository’s hooks directory.

Not running Git? Unfortunately, there’s some work you’ll need to do for now. We’re working on some new scripts for Subversion and Mercurial, but if you feel up to it, you can put together your own post-commit hook, based on ours. All the communication is taken care of for you by RBTools.

Speaking of RBTools

We’re gearing up for a major RBTools release, with the goal of shipping it this week. If all goes according to plan, we’ll be back next week with an overview of the new features, and how they’ll help you get your code posted and landed faster than ever.
