How can I debug a race condition in my C++ code?
Debugging race conditions can be tricky. Have you tried using tools like Valgrind or ThreadSanitizer?
I haven't used those tools. Can you explain how to use ThreadSanitizer?
Sure! You can enable ThreadSanitizer by adding -fsanitize=thread
to your compile command. It will help detect data races.
What should I look for in the output from ThreadSanitizer?
Look for messages indicating data races, which will show you the conflicting accesses to shared variables.
Are there any best practices to avoid race conditions in the first place?
Yes! Use mutexes for shared resources, avoid global variables, and consider using higher-level abstractions like futures.
