Go is a programming language that is particularly prone to concurrency bugs, with data race bugs being especially notorious for causing unexpected behavior. Consequently, debugging these issues is challenging. Since application developers may not be experts in concurrency, fixing these bugs can take hours. To address this issue, we have developed DrFix, an automated data race fixing tool that leverages a combination of program analysis and generative AI. In this talk, I will discuss how we have achieved automatically fixing hundreds of data races using DrFix.
