Tomasz, if people find it valuable, we'll definitely consider it. I'm most interested in investigating other projects who deploy onto high-traffic websites, and have relatively high-speed code review, merge, deploy, and release turnaround. A few places where we could grab ideas:
* OpenStack (I believe Ryan Lane mentioned that they integrate substantial volunteer contributions into an Agile process) * Mozilla (they successfully ask all contributors, including volunteers, to submit tests along with their patches)

Thanks for the nice report Sumana. Will we be doing deep dives like this with other open source projects?

At the request of a few folks, I've done some research on how the open source project Launchpad does code review and deployment.
In Launchpad, all developers are also code reviewers for about a day a week. All developers write "merge proposals" and attach them to their branches, and their colleagues review those branches and proposals within a day. Code reviewing is not primarily a gate to keep bugs out of code, but a social step, to get a second set of eyes on code, and to spread knowledge around. After code review, and automated testing on an EC2 instance, the developer lands the branch in trunk, a developer QAs it, and it gets deployed onto production in a matter of days or hours.
A few key differences from MediaWiki:
* No volunteer reviewers, small volunteer contributor community * Review trainees have already seen what a good code review lookslike, perhaps need less training * Started with backlog of less than a week's worth of commits
I've stuck a more detailed description here:

in case people want to get some ideas before the code review discussion tomorrow:
