What are the best practices for using ThreadSanitizer?

ThreadSanitizer is a powerful tool for detecting data races in your code. Best practices include enabling it during testing, using it with a variety of workloads, and analyzing the reports thoroughly.

How do I enable ThreadSanitizer in my project?

You can enable ThreadSanitizer by adding the -fsanitize=thread flag to your compiler options. Make sure to also link against the ThreadSanitizer runtime.

Are there any performance impacts when using ThreadSanitizer?

Yes, using ThreadSanitizer can slow down your program significantly, often by 2-20 times, depending on the workload. It's best used in testing environments.

Can ThreadSanitizer detect all types of data races?

ThreadSanitizer is very effective but may not catch every data race, especially in complex scenarios. It's important to combine it with other testing methods.
