Cracking the Nut - Open Sourcing from a Single Source Tree
Why a single source tree ? At a previous employer the code started out with the main code base in a single checkout with only infrastructure components of the code in their own repositories. As the code base grew the build time gradually become painful. To resolve this developers began to pull out components into their own repositories. This initially solved the problem of slow build times and improved productivity for the developers working on a single component. However, it soon became apparent that making changes to components that had many internal dependencies was particularly cumbersome. It also made it difficult to make changes across multiple repositories. This was solved by moving everything back into a single source tree. What about the slow build times? The short answer is Buck - a build tool from Facebook which is inspired by Google's internal build tool called Blaze, now open sourced as Bazel . In summary these build tools allow you to easily modularize your rep
