Large-Scale Refactoring @ Google

Log in to save this to your schedule and see who's attending!

Many organizations have significant investments in a large existing C++ codebase, and Google is no exception. Our code is intended to survive for decades, but continue to track new language standards as they emerge. To do so, we have developed tools and techniques which provide the ability to automatically refactor code to use new APIs as they become available.

In this talk, I'll discuss some of the reasons for doing migrations that impact hundreds of thousands of files, and how we do them at Google, using tools such as ClangMR. I'll give examples, such as our recent migration to the standardized std::unique_ptr and std::shared_ptr types and lessons we've learned from these experiences. Finally, I'll point out pitfalls others may face in doing similar work, and suggest ways that they can be avoided.
