Professor Xavier Leroy -- the primary original author and leader of the OCaml project -- reflects on 25 years of the OCaml language at his OCaml Workshop 2021 keynote speech.

In this talk, we will introduce a new tool called digodoc, that builds a graph of an opam switch, associating files, libraries and opam packages into a cyclic graph of inclusions and dependencies. We will then explain how we used that tool to buil...

This talk describes the process of generating documentation for every version of every package that can be built from the opam repository, and how it is presented as a single coherent website that is continuously updated as new packages are releas...

Regular CI systems are optimised for workloads that do not require stable performance over time. This makes them unsuitable for running performance benchmarks. current-bench provides a predictable environment for performance benchmarks and a UI...

The goal of this talk is two-fold. First, we present memprof-limits, a probabilistic implementation of per-thread global memory limits, and per-thread allocation limits, for OCaml 4.12. Then, we will discuss the reasoning about programs in the pre...

When testing a library, developers typically first have to capture the semantics they want to check. They then write the code implementing these tests and find relevant test cases that expose possible misbehaviours. In this work, we present a t...

Time handling is commonly considered a difficult problem by programmers due to myriad standards and complexity of time zone definitions. This also complicates scheduling across multiple time zones especially when one takes Daylight Saving Time int...

We develop ParaFuzz, an input and concurrency fuzzing tool for Multicore OCaml programs. ParaFuzz builds on top of Crowbar which combines AFL-based grey box fuzzing with QuickCheck and extends it to handle parallelism. Sumit Padhiyar Indian In...

We present the formal verification of a subset of the Set module from the OCaml standard library. The proof is conducted using Cameleer, a new tool for the deductive verification of OCaml code. Cameleer takes as input an OCaml program, annotated u...

OCaml 5.0 with support for shared-memory parallelism being around the corner, there’s increasing interest in the community to port existing libraries to Multicore. This talk will take the attendees through what the arrival of Multicore means to th...
