Verification of Concurrent Programs. Part I. The Temporal Framework,
Abstract
This is the first in a series of reports describing the application of temporal logic to the specification and verification of concurrent programs. We first introduce temporal logic as a tool for reasoning about sequences of states. Models of concurrent programs based both on transition graphs and on linear-text representations are presented and the notions of concurrent and fair executions are defined. The general temporal language is then specialized to reason about those execution sequences that are fair computations of a concurrent program. Subsequently, the language is used to describe properties of concurrent programs. The set of interesting properties is classified into invariance (safety), eventuality (liveness), and precedence (until) properties. Among the properties studied are: partial correctness, global invariance, clean behavior, mutual exclusion, absence of deadlock, termination, total correctness, intermittent assertions, accessibility, responsiveness, safe liveness, absence of unsolicited response, fair responsiveness, and precedence. In the following reports of this series, we will use the temporal formalism to develop proof methodologies for proving the properties discussed here. (Author)
