Function HandleCrash

pkg/util/runtime/runtime.go:48–61

HandleCrash simply catches a crash and logs an error. Meant to be called via defer. Additional context-specific handlers can be provided, and will be called in case of panic. HandleCrash actually crashes, after calling the handlers and logging the panic message. TODO: remove this function. We are

(additionalHandlers ...func(interface{}))

// catching panics was important. But it's actually much simpler for montoring
// software if we just exit when an unexpected panic happens.
func HandleCrash(additionalHandlers ...func(interface{})) {
	if r := recover(); r != nil {
		for _, fn := range PanicHandlers {
			fn(r)
		}
		for _, fn := range additionalHandlers {
			fn(r)
		}
		if ReallyCrash {
			// Actually proceed to panic.
			panic(r)
		}
	}
}

// logPanic logs the caller tree when a panic occurs.
func logPanic(r interface{}) {
