Ship it: a big week in Webtools

They say multi-tasking is hard. They also say DevOps is hard. Let me tell you about a bunch of engineers who think “hard” means “a nice challenge”.

Last week was an amazing one for the Webtools family. We pushed three releases to three major products. People inside Mozilla don’t always know exactly what types of things the Webtools team works on, so allow me to tell you about them.

1. Bouncer

Bouncer is Mozilla’s download redirector. When you click on one of those nifty “Download Firefox” buttons on, that takes you to Bouncer, which redirects you to the correct CDN or mirror where you can actually get the product that you want. Bouncer is also one of the oldest webapps at Mozilla, having been originally authored by my boss, Mike Morgan, many years ago.

Bouncer hadn’t had code changes in a very long time, and when we realized we needed to change it to support the new stub installer for Firefox, we had to spin up new development and staging environments. In addition, IT built out a new production cluster up to the new standards that have come into use since the last time it was deployed.

The code changes for stub installer are mainly around being intelligent enough to understand that some products, like the stub, can only be served from an SSL CDN or mirror. We don’t want to serve all products over SSL because of cost.

On Wednesday we shipped the new infrastrucure, and the code changes. You can read more about that it in bug 800042.

Thanks to Brandon Savage (Webtools), Anthony Ricaud (Websites), Fred Wenzel (Dev Ecosystem), Jake Maul (WebOps), Chris Turra (WebOps), Corey Shields (Systems), Stephen Donner (Web QA), Matt Brandt (Web QA), Raymond Etnoram (Web QA), and Ben Hearsum (RelEng) for making this possible.

2. Air Mozilla

As you probably know, Air Mozilla is the website that broadcasts Mozilla meetings, brownbags and presentations. On Friday we shipped a brand new version, built on top of Django. The old version was hosted in WordPress, and was really a simple way to present content. The new version has full calendaring integration, LDAP and BrowserID support, and better ways to find old presentations.

Thanks to Tim Mickel (Webtools Intern), Peter Bengtsson (Webtools), Richard Milewski (Air Mozilla), Zandr Milewski (SpecOps), Dan Maher (WebOps), Chris Turra (WebOps), Brandon Burton (WebOps), Jason Crowe (WebOps), and Corey Shields (Systems).

You can see details of the release in bug 799745.

3. Socorro

We also shipped a regular Wednesday Socorro release. Socorro is the crash reporting service for Mozilla products, including Firefox, Firefox for Mobile (“Fennec”), Firefox OS (“Boot to Gecko”), and Thunderbird.

In this release we shipped five bug fixes and enhancements. This number was a bit lower than usual, as most people are crunching to complete the front end rewrite (more on that in a moment).

You can read more about the release in bug 800140.

Thanks to the whole team for working on this: Adrian Gaudebert, Brandon Savage, Chris Lonnen, Lars Lohn, Peter Bengtsson, Robert Helmer, Schalk Neethling, Selena Deckelmann, and of course Matt Brandt (Web QA) and Brandon Burton (IT).

An aside: Socorro on Django

We are also very close to feature parity with the new Django-based version of the Socorro webapp to the old PHP webapp. We needed to rewrite this code, because the version of the framework used in the old version is four years out of date, and there was no upgrade path for it – newer versions break backwards compatibility. Since we had to rewrite it anyway, we have moved to use the same framework as the majority of other webapps at Mozilla. This allows for easier contributions by other Mozillians. We should reach parity in the next couple of days, and plan to ship the new code in parallel with the old, subject to secreview timing.


I am incredibly proud of the impact, quality, and sheer quantity of our work over the last weeks. These projects will enable many good things throughout Mozilla. Good work, people, stand tall.

Webtools is a small team, and we could not do what we do with incredible support from IT and QA. I like to think of this as the Webtools family: we are all one team; we all work together to get the job done come hell, high water, or zombies in the data center.

Just remember, there’s a reason the Webtools mascot is Ship It Squirrel.
