Stay Safe Under Panic: Affine Rust Programming with Multiparty Session Types (Artifact)

Authors: Nicolas Lagaillardie, Rumyana Neykova, and Nobuko Yoshida

Published in: DARTS, Volume 8, Issue 2, Special Issue of the 36th European Conference on Object-Oriented Programming (ECOOP 2022)

Abstract
This artifact contains a version of MultiCrusty, a Rust library designed for writing and checking communication protocols following the Affine Multiparty Session Types theory introduced in our ECOOP'22 paper. MultiCrusty can work, and should be used, with Scribble [Yoshida et al., 2014] and kMC [{Julien} {Lange} and {Nobuko} {Yoshida}, 2019]: with the former tool, users can write correct global protocols and project them onto local Rust types defined within MultiCrusty, this approach is qualified as top-down; while the latter tool allows to check local Rust types written by users, this approach is qualified as bottom-up. Our artifact contains those three tools, their respective source files, as well as the different examples and benchmarks introduced in our paper, all together within a Docker image.

Stay Safe Under Panic: Affine Rust Programming with Multiparty Session Types

Authors: Nicolas Lagaillardie, Rumyana Neykova, and Nobuko Yoshida

Published in: LIPIcs, Volume 222, 36th European Conference on Object-Oriented Programming (ECOOP 2022)

Abstract
Communicating systems comprise diverse software components across networks. To ensure their robustness, modern programming languages such as Rust provide both strongly typed channels, whose usage is guaranteed to be affine (at most once), and cancellation operations over binary channels. For coordinating components to correctly communicate and synchronise with each other, we use the structuring mechanism from multiparty session types, extending it with affine communication channels and implicit/explicit cancellation mechanisms. This new typing discipline, affine multiparty session types (AMPST), ensures cancellation termination of multiple, independently running components and guarantees that communication will not get stuck due to error or abrupt termination. Guided by AMPST, we implemented an automated generation tool (MultiCrusty) of Rust APIs associated with cancellation termination algorithms, by which the Rust compiler auto-detects unsafe programs. Our evaluation shows that MultiCrusty provides an efficient mechanism for communication, synchronisation and propagation of the notifications of cancellation for arbitrary processes. We have implemented several usecases, including popular application protocols (OAuth, SMTP), and protocols with exception handling patterns (circuit breaker, distributed logging).

Multiparty Session Programming with Global Protocol Combinators (Artifact)

Authors: Keigo Imai, Rumyana Neykova, Nobuko Yoshida, and Shoji Yuen

Published in: DARTS, Volume 6, Issue 2, Special Issue of the 34th European Conference on Object-Oriented Programming (ECOOP 2020)

Abstract
In the paper "Multiparty Session Programming with Global Protocol Combinators", we introduce a library, ocaml-mpst for programming with global combinators - a set of functions for writing and verifying multiparty protocols in OCaml. Local behaviours for all processes in a protocol are inferred at once from a global combinator. Our approach enables fully-static verification and implementation of the whole protocol, from the protocol specification to the process implementations, to happen in the same language. This artifact is the source code of ocaml-mpst, with all the examples and benchmarks discussed in the paper.

Multiparty Session Programming With Global Protocol Combinators

Authors: Keigo Imai, Rumyana Neykova, Nobuko Yoshida, and Shoji Yuen

Published in: LIPIcs, Volume 166, 34th European Conference on Object-Oriented Programming (ECOOP 2020)

Abstract
Multiparty Session Types (MPST) is a typing discipline for communication protocols. It ensures the absence of communication errors and deadlocks for well-typed communicating processes. The state-of-the-art implementations of the MPST theory rely on (1) runtime linearity checks to ensure correct usage of communication channels and (2) external domain-specific languages for specifying and verifying multiparty protocols. To overcome these limitations, we propose a library for programming with global combinators - a set of functions for writing and verifying multiparty protocols in OCaml. Local behaviours for all processes in a protocol are inferred at once from a global combinator. We formalise global combinators and prove a sound realisability of global combinators - a well-typed global combinator derives a set of local types, by which typed endpoint programs can ensure type and communication safety. Our approach enables fully-static verification and implementation of the whole protocol, from the protocol specification to the process implementations, to happen in the same language. We compare our implementation to untyped and continuation-passing style implementations, and demonstrate its expressiveness by implementing a plethora of protocols. We show our library can interoperate with existing libraries and services, implementing DNS (Domain Name Service) protocol and the OAuth (Open Authentication) protocol.
