Abstract

The upgrade of a running program is often a disruptive operation that involves stopping and restarting the program's execution, becoming, thus, a serious problem for dependable systems. Yet, software upgrades are unavoidable. Unfortunately, current solutions for dynamic software upgrades are either incomplete or not practical. In this paper, I layout the foundations for a new dynamic software upgrade system that provides atomic upgrades and is designed to integrate seamlessly with the current software development practices. This new upgrade system leverages on a software transactional memory to ensure that all the requests of an upgraded system are processed in a consistent state of the program, either before or after the upgrade.
