UNICA IRIS Institutional Research Information System
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Cagliari dal mese di luglio 2015.
EnglishAn extension of the lambda-calculus is proposed, to study resource usage analysis and verification. It features usage policies with a possibly nested, local scope, and dynamic creation of resources. We define a type and effect system that, given a program, extracts a history expression, i.e. a sound over-approximation to the set of histories obtainable at run-time. After a suitable transformation, history expressions are model-checked for validity. A program is resource-safe if its history expression is verified valid: if such, no run-time monitor is needed to safely drive its executions.

| Abstract: | An extension of the lambda-calculus is proposed, to study resource usage analysis and verification. It features usage policies with a possibly nested, local scope, and dynamic creation of resources. We define a type and effect system that, given a program, extracts a history expression, i.e. a sound over-approximation to the set of histories obtainable at run-time. After a suitable transformation, history expressions are model-checked for validity. A program is resource-safe if its history expression is verified valid: if such, no run-time monitor is needed to safely drive its executions. |
