What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A Go library providing drop-in replacements for sync.Mutex and sync.RWMutex that detect deadlocks at runtime. It records lock ordering per goroutine and reports violations or long lock waits with stack traces.
Use cases
- detect deadlocks in go programs
- find inconsistent mutex lock ordering
- debug goroutines stuck waiting on a lock
- replace sync.Mutex with a deadlock-aware mutex
- catch duplicate locking in the same goroutine
When to avoid
- your synchronization relies on channels rather than mutexes
- you cannot tolerate the runtime overhead in production
- locks are passed across goroutine boundaries, which defeats detection
