Data Races and the Limits of ThreadSanitizer
Learn about data races and the limitations of ThreadSanitizer in C and Go applications. Key insights for engineers.
To ensure code reliability, we write tests, but adding concurrency introduces nondeterministic bugs. Enabling a race detector like ThreadSanitizer (TSan) can help identify these issues. While TSan is widely used in languages like C and Go, its documentation is lacking, and it has limitations that can lead to missed data races. This article explores the fundamentals of data races and how TSan operates, highlighting its architectural constraints.
