LinuxCon Europe + CloudOpen Europe

Over the last three years the OpenStack developer community has grown from 60 to over 1000 active developers and to 1.3 million lines of code with over 2 thousand commits per month. According to Ohloh, ‘this is one of the largest open-source teams in the world, and is in the top 2% of all project teams on Ohloh.’ Keeping development running at this scale quickly becomes challenging, especially while trying to keep development as accessible possible. In this talk I will cover how our code review process has evolved to support this kind of exponential growth. We use many tools to streamline and automate the review process in order to reduce the burden on the reviewers. We have scaled and accelerated development by being strict and automatically enforcing our best practices.
