In this talk, I will cover a line of work (done jointly with Mooly and several other collaborators) that originated from TVLA and its application to verifying concurrent programs, but then took a different direction. I will talk about concurrency control protocols, and their usefulness in ensuring serializability. Shifting from an analysis and verification perspective, I will talk about use of synthesis to achieve correct-by-construction software (from a concurrency control perspective). I will discuss problems such as extending a sequential object to be a linearizable object, extending a linearizable object to be a transactional object, and composing multiple transactional objects into a single transactional object.
