Mailbox Abstractions for Static Analysis of Actor Programs (Artifact)

Authors: Quentin Stiévenart, Jens Nicolay, Wolfgang De Meuter, and Coen De Roover

Published in: DARTS, Volume 3, Issue 2, Special Issue of the 31st European Conference on Object-Oriented Programming (ECOOP 2017)

Abstract
This artifact is based on Scala-AM, a static analysis framework relying on the Abstracting Abstract Machines approach. This version of the framework is extended to support actor-based programs, written in a variant of Scheme. The sound static analysis is performed in order to verify the absence of errors in actor-based program, and to compute upper bounds on actor's mailboxes. We developed several mailbox abstractions with which the static analysis can be run, and evaluate the precision of the technique with these mailbox abstractions. This artifact contains documentation on how to use analysis and on how to reproduce the results presented in the companion paper.

Mailbox Abstractions for Static Analysis of Actor Programs

Authors: Quentin Stiévenart, Jens Nicolay, Wolfgang De Meuter, and Coen De Roover

Published in: LIPIcs, Volume 74, 31st European Conference on Object-Oriented Programming (ECOOP 2017)

Abstract
Properties such as the absence of errors or bounds on mailbox sizes are hard to deduce statically for actor-based programs. This is because actor-based programs exhibit several sources of unboundedness, in addition to the non-determinism that is inherent to the concurrent execution of actors. We developed a static technique based on abstract interpretation to soundly reason in a finite amount of time about the possible executions of an actor-based program. We use our technique to statically verify the absence of errors in actor-based programs, and to compute upper bounds on the actors' mailboxes. Sound abstraction of these mailboxes is crucial to the precision of any such technique. We provide several mailbox abstractions and categorize them according to the extent to which they preserve message ordering and multiplicity of messages in a mailbox. We formally prove the soundness of each mailbox abstraction, and empirically evaluate their precision and performance trade-offs on a corpus of benchmark programs. The results show that our technique can statically verify the absence of errors for more benchmark programs than the state-of-the-art analysis.
