| Beschreibung: | Why Java needs a CSP model • Many Java programs using threads seem to work correctly, but • Data races might be hidden • Deadlocks might not yet be detected • How can we be sure that data races and deadlocks in fact cannot occur? Why Java needs a CSP model • Solution: Model Java‘s synchronization facility in CSP • Allows us to reason in a formal way about its correct usage in Java programs • Synchronization primitives of Java‘s client interface that are modelled: • synchronized • wait(), notify(), notifyAll() Java Monitors in CSP • We model synchronized by the following CSP processes [1]: • STARTSYNC ( o, me) = claim.o.me ➔ SKIP • ENDSYNC ( o, me) = release.o.me ➔ SKIP Java Monitors in CSP • wait(), notify(), notifyAll() are modelled by the following CSP processes [1]: • WAIT(o, me) = waita.o.me ➔ release.o.me ➔ waitb.o.me ➔ claim.o.me ➔ SKIP • NOTIFY ( o, me) = notify.o.me ➔ SKIP • NOTIFYALL ( o, me) = notifyAll.o.me ➔ SKIP Java Monitors in CSP • Java‘s internal monitor facility for an object o is modelled by [1] |
