pkg mutexunlock

Automated fix tool for missing sync.Mutex or sync.RWMutex unlocks.

Installation

# go install github.com/Qs-F/mutexunlock

Usgae

Lint (without automated fix)

Run in the target project (if you are not sure, run in the directory which contains go.mod)

# go vet -vettool=$(which mutexunlock) .

Fmt (with automated fix)

For some reasons go vet command does not provide to pass flags to external vettool.

Run in the target project (if you are not sure, run in the directory which contains go.mod)

# mutexunlock -fix .

Example Behavior

If target code is like this:

type S struct {
	mu sync.Mutex
}

func (s *S) D() {
	s.mu.Lock()
	// You forgot s.mu.Unlock() here!
}

After Fmt (with automated fix),

type S struct {
	mu sync.Mutex
}

func (s *S) D() {
	s.mu.Lock()
+	s.mu.Unlock()
	// You forgot s.mu.Unlock() here!
}
