* Presentation
The goal of this workshop is to bring together researchers and build and
strengthen a community working on verification of session types using various
theorem provers such as Agda, Coq, Isabelle or any other.
Session types are abstract representations of the sequences of operations that
computational entities (such as channels or objects) must perform. Stateful
entities offer services in a non-uniform way (one cannot pop from an empty
stack); traditional type systems cannot guarantee that operations are only
invoked when the entity is in the right state.
Large-scale software systems rely on message-passing protocols: their
correctness largely depends on sound protocol implementations. Session types
can help in the specification of correct-by-construction systems, and in
verifying that programs respect their intended protocols.
Recent years have seen a steady stream of research on behavioural types: their
foundations and their transfer to several programming languages. This has led
to highly-cited papers in conferences such as POPL and journals such as TOPLAS.
Research projects on behavioural types have advanced the theory and
applications of behavioural types.
Although the foundations of session types are now well established, and new
works build on approaches that have become standard, there is still a lack of
reusable libraries, namely machine-verified ones. As on one hand the basis of
most works is common, and on the other hand the complexity of the formal
systems is considerable and may lead to errors in the proofs of the soundness
results, machine verifying the type systems proposed is vital. Libraries, or at
least clear formalisations of common approaches, is crucial to avoid not only
to repeat work but also to increase the confidence in the knowledge base.
Moreover, as many of these systems have a goal to do static analysis to ensure
some safety or liveness property, machine verification of these approaches
leads to certified software for program analysis.
The goal of the VEST workshop is to gather the researchers working on
mechanisations of behavioural types using various theorem provers, such as
Agda, Coq, Isabelle or any other. The workshop will be a platform to present
both the now well-established efforts and the ongoing works the community has
put on verification. The workshop will also be a forum to discuss strengths and
weaknesses of existing approaches, potential obstacles and to foster
collaboration.
