Language: Go

Severity: Info

Category: Best Practices

Empty critical sections are often a mistake. Instead of unlocking, developers often miss using defer to defer unlocking the mutex.

func test() {
    mutex.Lock()
    defer mutex.Lock()
}

func test() {
    mutex.Lock()
    defer mutex.Unlock()
}
