  • I'm not very familiar with golang but if you have some sort of thread id, you could keep a dictionary of threads to held locks. If that works, you can surely build a simple function which abstracts the check to see if the current thread already has a lock on the mutex before attempting to acquire it. It kind of seems like that should be automatic though. That is, a thread trying to acquire a lock it already holds should be a no-op. Commented Jul 20, 2023 at 20:06
