Definite Reference Mutability

Authors: Ana Milanova

Published in: LIPIcs, Volume 109, 32nd European Conference on Object-Oriented Programming (ECOOP 2018)


Abstract
Reference immutability type systems such as Javari and ReIm ensure that a given reference cannot be used to mutate the referenced object. These systems are conservative in the sense that a mutable reference may be mutable due to approximation. In this paper, we present ReM (for definite Re[ference] M[utability]). It separates mutable references into (1) definitely mutable, and (2) maybe mutable, i.e., references whose mutability is due to inherent approximation. In addition, we propose a CFL-reachability system for reference immutability, and prove that it is equivalent to ReIm/ReM, thus building a novel framework for reasoning about correctness of reference immutability type systems. We have implemented ReM and applied it on a large benchmark suite. Our results show that approximately 86.5% of all mutable references are definitely mutable.

Definite Reference Mutability (Artifact)

Authors: Ana Milanova and Wei Huang

Published in: DARTS, Volume 4, Issue 3, Special Issue of the 32nd European Conference on Object-Oriented Programming (ECOOP 2018)


Abstract
Related paper "Definite Reference Mutability" presents ReM (Re[ference] M[utability]), a type system that separates mutable references into (1) definitely mutable, and (2) maybe mutable, i.e., references whose mutability is due to inherent approximation. We have implemented ReM and applied it on a large benchmark suite. Results show that ~ 86\% of mutable references are definitely mutable. This article describes the tool artifact from the related paper. The purpose of the article and artifact is to allow researchers to reproduce our results, as well as build new type systems upon our code.
