Hatta bu binlerce *path operation* 3 satır kadar kısa olabilir:

{* ../../docs_src/security/tutorial002_an_py310.py hl[30:32] *}

## Özet { #recap }

Artık *path operation function* içinde mevcut kullanıcıyı doğrudan alabilirsiniz.

Yolun yarısına geldik.

Kullanıcının/istemcinin gerçekten `username` ve `password` göndermesini sağlayacak bir *path operation* eklememiz gerekiyor.

        srvsvc.ShareInfo0 shareInfo0 = new srvsvc.ShareInfo0();
        shareInfo0.netname = "TestShare";

        shareInfo0.encode(mockNdrBuffer);

        // Verify the encode operations
        verify(mockNdrBuffer).align(4);
        verify(mockNdrBuffer).enc_ndr_referent("TestShare", 1);
        verify(mockDeferredBuffer).enc_ndr_string("TestShare");
    }

    @Test

	for i := range osMetricLast {
		if n := atomic.LoadUint64(&o.operations[i]); n > 0 {
			m.LifeTimeOps[i.String()] = n
		}
	}
	if len(m.LifeTimeOps) == 0 {
		m.LifeTimeOps = nil
	}

	m.LastMinute.Operations = make(map[string]madmin.TimedAction, osMetricLast)
	for i := range osMetricLast {
		lm := o.latency[i].total()
		if lm.N > 0 {
			m.LastMinute.Operations[i.String()] = lm.asTimedAction()
		}
	}

* eine Remote-API-Operation beendet wurde
* Eine Datenbankoperation abgeschlossen wurde
* eine Datenbankabfrage die Ergebnisse zurückgegeben hat
* usw.

Da die Ausführungszeit hier hauptsächlich durch das Warten auf <abbr title="Input and Output - Eingabe und Ausgabe">I/O</abbr>-Operationen verbraucht wird, nennt man dies auch „I/O-lastige“ („I/O bound“) Operationen.
