Clousot: Static Contract Checking with Abstract Interpretation
We present an overview of Clousot, our current tool to statically check CodeContracts. CodeContracts enable a compiler and languageindependent specification of Contracts (precondition, postconditions and object invariants). Clousot checks every method in isolation using an assume/guarantee reasoning: For each method under analysis Clousot assumes its precondition and asserts the postcondition. ...
متن کاملStatic Contract Checking via First-Order Logic
We enrich the static semantics of Haskell in order to give stronger static guarantees about the input/output behavior of programs. Our approach has two parts: a contract system for Haskell, and a novel strategy for statically checking that a term satisfies a contract. The contract system includes refinement types, which refine Haskell types by arbitrary Boolean-valued Haskell expressions, and a...
متن کاملCombining Static and Dynamic Contract Checking for Curry
Static type systems are usually not sufficient to express all requirements on function calls. Hence, contracts with preand postconditions can be used to express more complex constraints on operations. Contracts can be checked at run time to ensure that operations are only invoked with reasonable arguments and return intended results. Although such dynamic contract checking provides more reliabl...
متن کاملA static semantics for Haskell
This paper gives a static semantics for Haskell 98, a non-strict purely functional programming language. The semantics formally speciies nearly all the details of the Haskell 98 type system, including the resolution of overloading, kind inference (including defaulting) and polymorphic recursion, the only major omission being a proper treatment of ambiguous overloading and its resolution. Overlo...
متن کاملStatic Contract Simplification
Contracts and contract monitoring are a powerful mechanism for specifying properties and guaranteeing them at run time. However, run time monitoring of contracts imposes a significant overhead. The execution time is impacted by the insertion of contract checks as well as by the introduction of proxy objects that perform delayed contract checks on demand. Static contract simplification attacks t...
