This paper describes a framework that supports powerful queries in debugging tools, and describes in particular the transformations, alias analysis, and type analysis used to make the queries efficient. The framework allows queries over the states of all objects at any point in the execution as well as over the history of states. The transformations are based on incrementally maintaining the results...
In this paper, we introduce the new technique of high-confidence software monitoring (HCSM), which allows one to perform software monitoring with bounded overhead and concomitantly achieve high confidence in the observed error rates. HCSM is formally grounded in the theory of supervisory control of finite-state automata: overhead is controlled, while maximizing confidence, by disabling interrupts...
