The kind of bagel that ruins lesser bagels for you.
Summary
Deadlog is a Go library for debugging mutex deadlocks that provides logged wrappers around sync.Mutex and sync.RWMutex. It offers features like tracking unreleased locks with correlation IDs, named callsites for labeling lock operations, and JSON event logging to help developers identify and resolve deadlock issues in Go code. The library maintains API compatibility with standard Go mutexes while adding debugging capabilities.

· 4 pulledA Go library for debugging mutex deadlocks with logged wrappers and analysis tools.
Replace sync.Mutex or sync.RWMutex with deadlog.Mutex: The API is compatible with both sync.Mutex and sync.RWMutex.
Use LockFunc() or RLockFunc() to get correlated RELEASED events: This logs START, ACQUIRED, and RELEASED events with the same correlation ID, making it easy to identify which lock was never released.
Use WithLockName() to label individual lock operations on the same mutex: Combined with WithTrace(1), the JSON events pinpoint ex
