-We present a framework for sandboxing and restricting features of the OCaml programming language to effectively automate the grading of programming exercises, scaling to hundreds of submissions. We describe how to disable language and library features that should not be used to solve a given exercise. We present an overview of an implementation of a mock IO system to allow testing of IO-related exercises in a controlled environment. Finally, we detail a number of security considerations to ensure submitted code remains sandboxed, allowing automatic grading to be trusted without manual verification. The source code of our implementation is publicly available [1].

[OCaML'23] MetaOCaml Theory and Implementation
-Oleg Kiselyov
-Quasi-quotation (or, code templates) has long been used as a convenient tool for code generation, commonly implemented as a pre-processing/translation into code-generation combinators. The original MetaOCaml was also based on such translation, done post type checking. BER MetaOCaml employs a significantly different, efficient (especially in version N114) translation integrated with type-checking, in the least intrusive way. This paper presents the integrated efficient translation for the first time.

-In particular, we found that some advanced practices, while accepted among the hardcore OCaml developers (e.g. use of row type variables through object types), lacked visibility and documentation: some of them deserve to be better known.
-Our experience is based on the Catala compiler, a DSL for the implementation of algorithms defined in law.
[OCaML'23] Osiris: an Iris-based program logic for OCaml
-Arnaud Daby-Seesaram, François Pottier, Armaël Guéneau
-Osiris is a project that aims to help OCaml developers verify their code using Separation Logic. The project is still young: we currently only support a subset of the features of the OCaml language, including modules, mutual recursion, ADTs, tuples and records. Ultimately, we would like to extend Osiris to support most features of the OCaml language. Iris is a Coq framework for Separation Logic with support for expressive ghost states. It is often used to define program logics and can be parameterized by a programming language — usually described by its small-steps semantics. Most Iris instantiations target ML-like languages, each focusing on a specific purpose and lacking support of programming features such as records or ADTs. Osiris contains an Iris instantiation with a presentation of the semantics of OCaml, in order to reason on realistic OCaml programs. Osiris provides a translation tool to convert OCaml files to Coq files (cf. section 2). In order to verify an OCaml program with Osiris, one would use the translator on an OCaml file, seen as a module. This produces a Coq file containing a deep-embedded representation me of the module. The user would then write and prove a specification for the interpretation of me in our semantics.

-Léo Andrès, Pierre Chambart, Eric Patrizio, Dario Pinto
-This presentation introduces Owi, an OCaml-based interpreter and toolkit for WebAssembly (Wasm). Owi aims to provide a fast and easily maintainable solution for Wasm code execution. Unlike competing interpreters, Owi focuses on facilitating experimentation, research, and symbolic manipulations of Wasm. We describe the different passes and intermediate representations of Owi. Additionally, we discuss the linker, the interpreter and its support for various Wasm-specific extensions. Owi’s API leverages Generalized Algebraic Data Types (GADTs) for improved error detection at link-time. We also describe the testing methods used, including a Crowbar-based fuzzer. Future work includes incorporating missing Wasm extensions, implementing advanced optimization passes, and potentially porting the WASP execution engine to perform concolic execution.

-I present my implementation of a parallel sequences abstraction that utilizes the support for shared memory parallelism in the new OCaml 5.0.0 multicore runtime. This abstraction allows clients to create highly parallelizable programs without needing to write, or even understand, the low-level implementation details necessary to parallelize large tasks.

-Thibaut Mattio, Anil Madhavapeddy, Thomas Gazagnaire, David Allsopp
-This paper reflects on a decade of progress and developments within the OCaml Platform, from its inception in 2013 with the release of opam 1.0, to today where it stands as a robust toolchain for OCaml developers. We review the last three years in detail, emphasizing the advancements and innovations that have shaped the OCaml development landscape and highlighting key milestones such as the migration to Dune as the primary build system, and the development of a Language Server Protocol (LSP) server for OCaml.
-We also outline our plan for the coming years. The roadmap is informed by community feedback, discussions with Platform tool maintainers, and insights from industrial users of OCaml. The final version of this evolving roadmap, designed to shape the future of the OCaml developer experience, will be presented at the International Conference on Functional Programming (ICFP).
[OCaML'23] Targeted Static Analysis for OCaml C Stubs: Eliminating gremlins from the code
-Edwin Török
-Migration to OCaml 5 requires updating a lot of C bindings due to the removal of naked pointer support. Writing OCaml user-defined primitives in C is a necessity, but is unsafe and error-prone. It does not benefit from either OCaml’s or C’s type checking, and existing C static analysers are not aware of the OCaml GC safety rules, and cannot infer them from existing macros alone. The alternative is automatically generating C stubs, which requires correctly managing value lifetimes. Having a static analyser for OCaml to C interfaces is useful outside the OCaml 5 porting effort too.
-After some motivating examples of real bugs in C bindings a static analyser is presented that finds these known classes of bugs. The tool works on the OCaml abstract parse and typed trees, and generates a header file and a caller model. Together with a simplified model of the OCaml runtime this is used as input to a static analysis framework, Goblint. An analysis is developed that tracks dereferences of OCaml values, and together with the existing framework reports incorrect dereferences. An example is shown how to extend the analysis to cover more safety properties.
-The tools and runtime models are generic and could be reused with other static analysis tools.
This presentation gives an overview of the Ocsigen framework, which is used in particular to develop the Be Sport social network. Ocsigen is a set a tools to develop Web sites and applications. Amongst other things, it contains js_of_ocaml, a compiler to Javascript, and Eliom, a powerful Web framework that can be used for traditional server-side Web programming, but also to develop client-server Web and mobile distributed applications, fully in OCaml, using multi-tier programming. This programming style can save a huge amount of time.

-With the release of OCaml 5 and its support for effect handlers, the new concurrency library Eio was proposed which aims to replace previous monadic concurrency libraries for OCaml.
-In this work we verify the core fiber and promise abstractions of Eio and show their safety and effect safety using the Hazel program logic.
-Hazel is built on the Iris framework and allows reasoning about programs with effect handlers. We also adapt the existing proof of the verified CQS datastructure since Eio uses a customized version of CQS for its implementation of promises.
-We do not treat some features of Eio like cancellation, because it does not yield a verifiable specification, and resource control using switches, since it is a liveness property.
