Abstract

Concurrent objects can be accessed and possibly modified concurrently by several running processes. It is notoriously difficult to make sure that such objects are consistent with – and are used according to – their intended protocol. In this paper we detail a type checking algorithm for concurrent objects protocols that provides automated support for this verification task. We model concurrent objects in the Objective Join Calculus and specify protocols using terms of a Commutative Kleene Algebra. The presented results are an essential first step towards the application of this static analysis technique to real-world programs.
