Just a general question: why do you put log.Error in all the error handlers? Wouldn't it be better to put the log.Error in the caller of the method?

[JoaoAndreSa]

@ineiti I tried to add log.Error in a way so that it would be easy to debug. The problem of what I had before (where I just threw every error and only printed at the uppermost function) was that then I had no idea where the error came from. :(

I had no idea where the error came from. :(

Yes, I had the same. As an experiment, when I threw an existing error, I first had it pass through something like:

func Erret(err error) error {
	if err == nil {
		return nil
	}
	pc, _, line, _ := runtime.Caller(1)
	errStr := err.Error()
	if strings.HasPrefix(errStr, "Erret") {
		errStr = "\n\t" + errStr
	}
	return fmt.Errorf("Erret at %s: %d -> %s", runtime.FuncForPC(pc).Name(), line, errStr)
}

and then you could see the 'trace' of where the error comes from. But I'm sure there is a better way for that...
