Linear Promises: Towards Safer Concurrent Programming (Artifact)

Authors: Ohad Rau, Caleb Voss, and Vivek Sarkar

Published in: DARTS, Volume 7, Issue 2, Special Issue of the 35th European Conference on Object-Oriented Programming (ECOOP 2021)

Abstract
We present a compiler for a concurrent programming language, which utilizes linear typing to create a safer promise abstraction. The compiler is implemented in OCaml and produces source-level Java code. We provide example programs to demonstrate use of the language, as well as translations of incorrect JavaScript code from StackOverflow to showcase the ability of our language to catch many classes of bugs. Finally, we provide a minimal runtime environment to allow the execution of compiled programs.

Linear Promises: Towards Safer Concurrent Programming

Authors: Ohad Rau, Caleb Voss, and Vivek Sarkar

Published in: LIPIcs, Volume 194, 35th European Conference on Object-Oriented Programming (ECOOP 2021)

Abstract
In this paper, we introduce a new type system based on linear typing, and show how it can be incorporated in a concurrent programming language to track ownership of promises. By tracking write operations on each promise, the language is able to guarantee exactly one write operation is ever performed on any given promise. This language thus precludes a number of common bugs found in promise-based programs, such as failing to write to a promise and writing to the same promise multiple times. We also present an implementation of the language, complete with an efficient type checking algorithm and high-level programming constructs. This language serves as a safer platform for writing high-level concurrent code.
