Automating dead code cleanup

Automating dead code cleanup

摘要

In our last blog post on automatic product deprecation, we talked about the complexities of product deprecations, and a solution Meta has built called the Systematic Code and Asset Removal Framework (SCARF). As an example, we looked at Moments, the photo sharing app Meta launched in 2015 and eventually shut down in 2019, and how SCARF can help with the deprecation process through its workflow management capabilities. We discussed how SCARF saves engineering time by identifying the correct order of tasks for cleaning up a product and how it can be blocked from automating the cleanup when there are intersystem dependencies. This naturally leads to the question: How do we automatically unblock SCARF when there is code that references an asset?
