MessageObserving Sessions
We present Most, a process language with messageobserving session types. Messageobserving session types extend binary session types with typelevel computation to specify communication protocols that vary based on messages observed on other channels. Hence, Most allows us to express global invariants about processes, rather than just local invariants, in a bottomup, compositional way. We give Most a semantic foundation using traces with binding, a semantic approach for compositionally reasoning about traces in the presence of name generation. We use this semantics to prove type soundness and compositionality for Most processes. We see this as a significant step towards capturing messagedependencies and providing more precise guarantees about processes.
