Abstract During iterative, UML-based software development, various UML diagrams, modeling the same system at different levels of abstractions are developed. These models must remain consistent when changes are performed. In this context, we refine the notion of impact analysis and distinguish horizontal impact analysis-that focuses on changes and impacts at one level of abstraction, and vertical impact analysis-that focuses on changes at one level of abstraction and their impacts on another level. We propose a vertical impact analysis approach for UML 2.0 models which is based on a careful formalization of changes to those models, refinements which are composed of those changes, and traceability links corresponding to refinements. We show how actual refinements and corresponding traceability links are formalized using the Object Constraint Language. Tool support and an initial case study are also described. 3 Reproduced with permission of the copyright owner. Further reproduction prohibited without permission.

  • Gradual Liquid Type Inference
    Gradual Liquid Type Inference NIKI VAZOU, IMDEA, Spain ÉRIC TANTER, University of Chile, Chile DAVID VAN HORN, University of Maryland, USA Refinement types allow for lightweight program verification by enriching types with logical predicates. Liquid typing provides a decidable refinement inference mechanism that is convenient but subject to two major issues: (1) inference is global and requires top-level annotations, making it unsuitable for inference of modular code components and prohibiting its applicability to library code, and (2) inference failure results in obscure error messages. These difficulties seriously hamper the migration of existing code to use refinements. This paper shows that gradual liquid type inferenceśa novel combination of liquid inference and gradual refinement typesśaddresses both issues. Gradual refinement types, which support imprecise predicates that are optimistically interpreted, can be used in argument positions to constrain liquid inference so that the global inference process effectively infers modular specifications usable for library components. Dually, when gradual refinements appear as the result of inference, they signal an inconsistency in the use of static refinements. Because liquid refinements are drawn from a finite set of predicates, in gradual liquid type inference wecan enumerate the safe concretizations of each imprecise refinement, i.e., the static refinements that justify why a program is gradually well-typed. This enumeration is useful for static liquid type error explanation, since the safe concretizations exhibit all the potential inconsistencies that lead to static type errors. We develop the theory of gradual liquid type inference and explore its pragmatics in the setting of Liquid 132 Haskell. To demonstrate the utility of our approach, we develop an interactive tool, GuiLT, for gradual liquid type inference in Liquid Haskell that both infers modular types and explores safe concretizations of gradual refinements.

  • Relatively Complete Refinement Type System for Verification of Higher-Order Non-Deterministic Programs
    Relatively Complete Refinement Type System for Verification of Higher-Order Non-deterministic Programs HIROSHI UNNO, University of Tsukuba, Japan YUKI SATAKE, University of Tsukuba, Japan TACHIO TERAUCHI, Waseda University, Japan This paper considers verification of non-deterministic higher-order functional programs. Our contribution is a novel type system in which the types are used to express and verify (conditional) safety, termination, non-safety, and non-termination properties in the presence of 8-9 branching behavior due to non-determinism. 88 For instance, the judgement ` e : u:int ϕ(u) says that every evaluation of e either diverges or reduces 98 to some integer u satisfying ϕ(u), whereas ` e : u:int ψ (u) says that there exists an evaluation of e that either diverges or reduces to some integer u satisfying ψ (u). Note that the former is a safety property whereas the latter is a counterexample to a (conditional) termination property. Following the recent work on type-based verification methods for deterministic higher-order functional programs, we formalize theideaon the foundation of dependent refinement types, thereby allowing the type system to express and verify rich properties involving program values, branching behaviors, and the combination thereof. Our type system is able to seamlessly combine deductions of both universal and existential facts within a unified framework, paving the way for an exciting opportunity for new type-based verification methods that combine both universal and existential reasoning. For example, our system can prove the existence of a path violating some safety property from a proof of termination that uses a well-foundedness termination 12 argument.

  • Refinement Session Types
    MENG INDIVIDUAL PROJECT IMPERIAL COLLEGE LONDON DEPARTMENT OF COMPUTING Refinement Session Types Supervisor: Prof. Nobuko Yoshida Author: Fangyi Zhou Second Marker: Dr. Iain Phillips 16th June 2019 Abstract We present an end-to-end framework to statically verify multiparty concurrent and distributed protocols with refinements, where refinements are in the form of logical constraints. We combine the theory of multiparty session types and refinement types and provide a type system approach for lightweight static verification. We formalise a variant of the l-calculus, extended with refinement types, and prove their type safety properties. Based on the formalisation, we implement a refinement type system extension for the F# language. We design a functional approach to generate APIs with refinement types from a multiparty protocol in F#. We generate handler-styled APIs, which statically guarantee the linear usage of channels. With our refinement type system extension, we can check whether the implementation is correct with respect to the refinements. We evaluate the expressiveness of our system using three case studies of refined protocols.

  • Local Refinement Typing
    Local Refinement Typing BENJAMIN COSMAN, UC San Diego RANJIT JHALA, UC San Diego 26 We introduce the Fusion algorithm for local refinement type inference, yielding a new SMT-based method for verifying programs with polymorphic data types and higher-order functions. Fusion is concise as the programmer need only write signatures for (externally exported) top-level functions and places with cyclic (recursive) dependencies, after which Fusion can predictably synthesize the most precise refinement types for all intermediate terms (expressible in the decidable refinement logic), thereby checking the program without false alarms. We have implemented Fusion and evaluated it on the benchmarks from the LiqidHaskell suite totalling about 12KLOC. Fusion checks an existing safety benchmark suite using about half as many templates as previously required and nearly 2× faster. In a new set of theorem proving benchmarks Fusion is both 10 − 50× faster and, by synthesizing the most precise types, avoids false alarms to make verification possible.

  • Refinement Type Inference Via Horn Constraint Optimization⋆
    Refinement Type Inference via Horn Constraint Optimization? Kodai Hashimoto and Hiroshi Unno University of Tsukuba fkodai, [email protected] Abstract. We propose a novel method for inferring refinement types of higher-order functional programs. The main advantage of the proposed method is that it can infer maximally preferred (i.e., Pareto optimal) refinement types with respect to a user-specified preference order. The flexible optimization of refinement types enabled by the proposed method paves the way for interesting applications, such as inferring most-general characterization of inputs for which a given program satisfies (or vi- olates) a given safety (or termination) property. Our method reduces such a type optimization problem to a Horn constraint optimization problem by using a new refinement type system that can flexibly rea- son about non-determinism in programs. Our method then solves the constraint optimization problem by repeatedly improving a current solu- tion until convergence via template-based invariant generation. We have implemented a prototype inference system based on our method, and obtained promising results in preliminary experiments. 1 Introduction Refinement types [5, 20] have been applied to safety verification of higher-order functional programs. Some existing tools [9, 10, 16{19] enable fully automated verification by refinement type inference based on invariant generation tech- niques such as abstract interpretation, predicate abstraction, and CEGAR. The goal of these tools is to infer refinement types precise enough to verify a given safety specification. Therefore, types inferred by these tools are often too specific to the particular specification, and hence have limited applications. To remedy the limitation, we propose a novel refinement type inference method that can infer maximally preferred (i.e., Pareto optimal) refinement types with respect to a user-specified preference order.

  • 1 Refinement Types
    1 Refinement Types This section is primarily based on Principles of Type Refinement, Noam Zeil- berger, OPLSS 2016 The concept of refinement types is quite general. So general, in fact, that it is not immediately obvious that the various publications claiming to present refinment type systems are founded upon a common framework. Nonetheless, Noam Zeilberger recently published a tutorial presenting such a framework. Before shifting to a more historical perspective, we will examine Zeilberger’s framework so that we understand the presented systems as refinement type systems rather than ad-hoc ones. Definition 1.1. Refinement type system: An extra layer of typing on an exist- ing type system. Remark 1.2. Type refinement systems are conservative: they preserve the properties of the underlying type system. The framework to be presented as- sumes the existing type system does not include subtyping. Definition 1.3 (Type syntax). T,S,U (types) ::= Int | Bool | T → T ρ,π,σ (refinements) ::= rInt | rBool | ρ → ρ Remark 1.4. A refinement type system decomposes each base type of the underlying system into a preordered set of base refinement types. In our example system, these sets (rInt and rBool) happen to be lattices. Definition 1.5 (Base refinements). Preorder h rInt, ≤Inti Preorder h rBool, ≤Booli 1Int NN NP 1Bool Z True False 0Int 0Bool Remark 1.6 (Type semantics). Recall that a type T can be interpreted as a set of closed values; e.g., JBoolK = {true,false} where true and false are values in a term language. For distinct S and T the underlying system should have JT K ∩ JSK = ∅.
