How to Take the Inverse of a Type (Artifact)
Abstract
In functional programming, regular types are a subset of algebraic data types formed from products and sums with their respective units. One can view regular types as forming a commutative semiring but where the usual axioms are isomorphisms rather than equalities. In the pearl, we show that regular types in a linear setting permit a useful notion of multiplicative inverse, allowing us to ‘divide’ one type by another. We begin with an exploration of the properties and applications of this construction, and this artifact includes examples in Haskell demonstrating its relevance to various topics from the literature including program calculation, Laurent polynomials, and derivatives of data types. Some examples from the paper require a richer setting than Haskell can offer; the artifact replays the first set of examples in Granule, while also presenting additional examples demonstrating further algebraic structure through linear functions that incorporate local side effects.

Compiling Volatile Correctly in Java (Artifact)
Abstract
The compilation scheme for Volatile accesses in the OpenJDK 9 HotSpot Java Virtual Machine has a major problem that persists despite a recent bug report and a long discussion. One of the suggested fixes is to let Java compile Volatile accesses in the same way as C/C++11. However, we show that this approach is invalid for Java. Indeed, we show a set of optimizations that is valid for C/C++11 but invalid for Java, while the compilation scheme is similar. We prove the correctness of the compilation scheme to Power and x86 and a suite of valid optimizations in Java. Our proofs are based on a language model that we validate by proving key properties such as the DRF-SC theorem and by running litmus tests via our implementation of Java in Herd7.

Direct Foundations for Compositional Programming (Artifact)
Abstract
Our companion paper proposes a new formulation of the 𝖥_{i}^{+} calculus with disjoint polymorphism and a merge operator based on Type-Directed Operational Semantics. The artifact contains Coq formalization of the 𝖥_{i}^{+} calculus and our new implementation of the CP language, which demonstrates the new 𝖥_{i}^{+} can serve as the direct foundation for Compositional Programming.

Elementary Type Inference (Artifact)
Abstract
This artifact contains the Appendix of the paper, proofs of theorems declared in the paper, and a sample implementation of the type inference algorithm. The proof contains 3 main results: soundness, completness and decidability of the type-inference algorithm. Moreover, there are several proofs about the declarative system and also a soundness/completeness proof between stable subtyping and a syntax-directed specification.

Qilin: A New Framework for Supporting Fine-Grained Context-Sensitivity in Java Pointer Analysis (Artifact)
Abstract
Existing whole-program context-sensitive pointer analysis frameworks for Java, which were open-sourced over one decade ago, were designed and implemented to support only method-level context-sensitivity (where all the variables/objects in a method are qualified by a common context abstraction representing a context under which the method is analyzed). We introduce Qilin as a generalized (modern) alternative, which will be open-sourced soon on GitHub, to support the current research trend on exploring fine-grained context-sensitivity (including variable-level context-sensitivity where different variables/objects in a method can be analyzed under different context abstractions at the variable level), precisely, efficiently, and modularly. To meet these four design goals, Qilin is developed as an imperative framework (implemented in Java) consisting of a fine-grained pointer analysis kernel with parameterized context-sensitivity that supports on-the-fly call graph construction and exception analysis, solved iteratively based on a new carefully-crafted incremental worklist-based constraint solver, on top of its handlers for complex Java features.
We have evaluated Qilin extensively using a set of 12 representative Java programs (popularly used in the literature). For method-level context-sensitive analyses, we compare Qilin with Doop (a declarative framework that defines the state-of-the-art), Qilin yields logically the same precision but more efficiently (e.g., 2.4x faster for four typical baselines considered, on average). For fine-grained context-sensitive analyses (which are not currently supported by open-source Java pointer analysis frameworks such as Doop), we show that Qilin allows seven recent approaches to be instantiated effectively in our parameterized framework, requiring additionally only an average of 50 LOC each.

Automatic Root Cause Quantification for Missing Edges in JavaScript Call Graphs (Artifact)
Abstract
Building sound and precise static call graphs for real-world JavaScript applications poses an enormous challenge, due to many hard-to-analyze language features. Further, the relative importance of these features may vary depending on the call graph algorithm being used and the class of applications being analyzed. In this paper, we present a technique to automatically quantify the relative importance of different root causes of call graph unsoundness for a set of target applications. The technique works by identifying the dynamic function data flows relevant to each call edge missed by the static analysis, correctly handling cases with multiple root causes and inter-dependent calls. We apply our approach to perform a detailed study of the recall of a state-of-the-art call graph construction technique on a set of framework-based web applications. The study yielded a number of useful insights. We found that while dynamic property accesses were the most common root cause of missed edges across the benchmarks, other root causes varied in importance depending on the benchmark, potentially useful information for an analysis designer. Further, with our approach, we could quickly identify and fix a recall issue in the call graph builder we studied, and also quickly assess whether a recent analysis technique for Node.js-based applications would be helpful for browser-based code. All of our code and data is publicly available, and many components of our technique can be re-used to facilitate future studies.

Functional Programming for Distributed Systems with XC (Artifact)
Abstract
In the paper "Functional programming for distributed systems with XC" we present XC, a programming language to develop the collective behaviour of homogeneous distributed systems while abstracting over concurrency, asynchronous execution, message loss, and device failures. The paper describes the design of XC, formalizes a core calculus for it, and shows that XC can effectively capture the logic of several distributed protocols and applications including gossiping, distributed summarization, information flows over self-healing communication structures, and self-organizing behaviours. Then, it discusses implementation, in a Scala and a C++ embedded domain-specific language (DSL), and provides evaluation through a case study in a smart city scenario, called SmartC. The reusable artifact described in this paper contains precisely those software projects: the Scala DSL, referred to as XC/Scala; the C++ DSL, referred to as XC/C++; and the SmartC implementation in both DSLs.

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

Verified Compilation and Optimization of Floating-Point Programs in CakeML (Artifact)
Abstract
Verified compilers such as CompCert and CakeML have become increasingly realistic over the last few years, but their support for floating-point arithmetic has thus far been limited. In particular, they lack the "fast-math-style" optimizations that unverified mainstream compilers perform. Supporting such optimizations in the setting of verified compilers is challenging because these optimizations, for the most part, do not preserve the IEEE-754 floating-point semantics. However, IEEE-754 floating-point numbers are finite approximations of the real numbers, and we argue that any compiler correctness result for fast-math optimizations should appeal to a real-valued semantics rather than the rigid IEEE-754 floating-point numbers.
This document describes the artifact for RealCake, an extension of CakeML that achieves end-to-end correctness results for fast-math-style optimized compilation of floating-point arithmetic. This result is achieved by giving CakeML a flexible floating-point semantics and integrating an external proof-producing accuracy analysis. RealCake’s end-to-end theorems relate the I/O behavior of the original source program under real-number semantics to the observable I/O behavior of the compiler generated and fast-math-optimized machine code.

Prisma: A Tierless Language for Enforcing Contract-Client Protocols in Decentralized Applications (Artifact)
Abstract
Decentralized applications (dApps) consist of smart contracts that run on blockchains and clients that model collaborating parties. dApps are used to model financial and legal business functionality. Today, contracts and clients are written as separate programs - in different programming languages - communicating via send and receive operations. This makes distributed program flow awkward to express and reason about, increasing the potential for mismatches in the client-contract interface, which can be exploited by malicious clients, potentially leading to huge financial losses. In this paper, we present Prisma, a language for tierless decentralized applications, where the contract and its clients are defined in one unit. Pairs of send and receive actions that “belong together” are encapsulated into a single direct-style operation, which is executed differently by sending and receiving parties. This enables expressing distributed program flow via standard control flow and renders mismatching communication impossible. We prove formally that our compiler preserves program behavior in presence of an attacker controlling the client code. We systematically compare Prisma with mainstream and advanced programming models for dApps and provide empirical evidence for its expressiveness and performance.

Union Types with Disjoint Switches (Artifact)
Abstract
This artifact contains the mechanical formalization of the calculi associated with the paper Union Types with Disjoint Switches. All of the metatheory has been formalized in Coq theorem prover. We provide a docker image as well the code archive.
The paper studies a union calculus ({λ_{u}}). Primary idea of {λ_{u}} calculus is a type based disjoint switch construct for the elimination of union types. We also study several extensions of the {λ_{u}} calculus including intersection types, distributive subtyping, nominal types, parametric polymorphism and an extension for the empty types.

Global Type Inference for Featherweight Generic Java - Prototype Implementation (Artifact)
Abstract
We implemented a prototype of the type inference algorithm described in the paper "Global Type Inference for Featherweight Generic Java". Our type inference algorithm for Featherweight Generic Java (GFJ) is able to calculate the missing types in a Typeless Featherweight Generic Java (FGJ-GT) program. Inserting those types generates a valid GFJ program. We demonstrate this with a prototype implementation. The prototype is a web application which accepts GFJ-GT programs as input and shows the respective GFJ program after the type inference.

API Generation for Multiparty Session Types, Revisited and Revised Using Scala 3 (Artifact)
Abstract
Construction and analysis of distributed systems is difficult. Multiparty session types (MPST) constitute a method to make it easier. The idea is to use type checking to statically prove deadlock freedom and protocol compliance of communicating processes. In practice, the premier approach to apply the MPST method in combination with mainstream programming languages has been based on API generation. With this artifact, and the companion paper, we revisit and revise this approach.
Regarding our "revisitation", using Scala 3, we present the existing API generation approach, which is based on deterministic finite automata (DFA), in terms of both the existing states-as-classes encoding of DFAs as APIs, and a new states-as-type-parameters encoding; the latter leverages match types in Scala 3. Regarding our "revision", also using Scala 3, we present a new API generation approach that is based on sets of pomsets instead of DFAs; it crucially leverages match types, too. Our fresh perspective allows us to avoid two forms of combinatorial explosion resulting from implementing concurrent subprotocols in the DFA-based approach. We implement our approach in a new API generation tool, called Pompset. This artifact contains Pompset.

Concolic Execution for WebAssembly (Artifact)
Abstract
This artifact contains the implementation of WASP, a symbolic execution engine for Wasm, and WASP-C, a symbolic execution framework for testing C programs built using WASP . WASP works directly on Wasm code and was built on top of a standard-compliant Wasm reference implementation [Andreas Haas et al., 2017]. WASP was thoroughly evaluated: it was used to symbolically test a generic data-structure library and the Amazon Encryption SDK for C, demonstrating that it can find bugs and generate high-coverage testing inputs for real-world C applications; WASP was further tested against the Test-Comp benchmark, obtaining results comparable to well-established symbolic execution and testing tools for C.

Design-by-Contract for Flexible Multiparty Session Protocols (Artifact)
Abstract
We introduce CAScr, the first implementation of Scribble (http://www.scribble.org, https://nuscr.dev/) that relies on choreography automata, for deadlock-free distributed programming. CAScr supports the main theoretical results and constructions in the related article. CAScr takes the popular top-down approach to system development, based on choreographic models, following the original methodology of Scribble and multiparty session types. The top-down approach enables correctness-by-construction: a developer provides a global description for the whole communication protocol; by projecting the global protocol, APIs are generated from local CFSMs, which ensure the safe implementation of each participant. The theory of choreography automata in the related article guarantees deadlock freedom for the distributed implementation of flexible global protocols. We target web development, supporting in particular the TypeScript programming language.

Accumulation Analysis (Artifact)
Abstract
This artifact contains the data and analysis supporting the literature survey in section 4 of [Kellogg et al., 2022]. In our literature survey, we examined 187 papers from the literature that mention "typestate" and analyzed the typestate specifications they contained to determine whether or not they are accumulation typestate specifications.
Our purpose in doing this literature survey was to determine whether typestate FSMs were accumulation or not. However, we believe that the collection of typestate automata in typestates.pdf might be useful to anyone interested in the sort of typestate automata that appear in the literature. If we had had access to such a collection (gathered for a different purpose), our classification of whether these typestate automata were accumulation would have been much simpler. Anyone interested in properties of typestate automata can re-use our work.

JavaScript Sealed Classes (Artifact)
Abstract
In this work, we study the JavaScript Sealed Classes, which differ from regular classes in a few ways that allow ahead-of-time (AoT) compilers to implement them more efficiently. Sealed classes are compatible with the rest of the language so that they can be combined with all other structures, including regular classes, and can be gradually integrated into existing code bases.
We present the design of the sealed classes and study their implementation in the hopc AoT compiler. We present an in-depth analysis of the speed of sealed classes compared to regular classes. To do so, we assembled a new suite of benchmarks that focuses on the efficiency of the class implementations. On this suite, we found that sealed classes provide an average speedup of 19%. The more classes and methods programs use, the greater the speedup. For the most favorable test that uses them intensively, we measured a speedup of 56%.

PEDroid: Automatically Extracting Patches from Android App Updates (Artifact)
Abstract
We propose an approach to automatically identify and extract patches from updated Android apps by comparing the updated versions and their predecessors. PEDroid, a prototype patch extraction tool against Android apps, consists of two phases: differential analysis and patch identification. We evaluated it with a set of popular open-source apps to demonstrate its effectiveness. PEDroid achieves a recall of 92% in differential analysis and successfully identifies 28 of 36 patches in patch identification. We also provide specific guidance on reproducing the experimental results.

Synchron - An API and Runtime for Embedded Systems (Artifact)
Abstract
Programming embedded applications involves writing concurrent, event-driven and timing-aware programs. Traditionally, such programs are written in machine-oriented programming languages like C or Assembly. We present an alternative by introducing Synchron, an API that offers high-level abstractions to the programmer while supporting the low-level infrastructure in an associated runtime system and one-time-effort drivers.
Embedded systems applications exhibit the general characteristics of being (i) concurrent, (ii) I/O-bound and (iii) timing-aware. To address each of these concerns, the Synchron API consists of three components - (1) a Concurrent ML (CML) inspired message-passing concurrency model, (2) a message-passing-based I/O interface that translates between low-level interrupt based and memory-mapped peripherals, and (3) a timing operator, syncT, that marries CML’s sync operator with timing windows inspired from the TinyTimber kernel.
We implement the Synchron API as the bytecode instructions of a virtual machine called SynchronVM. SynchronVM hosts a Caml-inspired functional language as its frontend language, and the backend of the VM supports the STM32F4 and NRF52 microcontrollers, with RAM in the order of hundreds of kilobytes. We illustrate the expressiveness of the Synchron API by showing examples of expressing state machines commonly found in embedded systems. The timing functionality is demonstrated through a music programming exercise. Finally, we provide benchmarks on the response time, jitter rates, memory, and power usage of the SynchronVM.
