Request-Based Mediated Execution

ProQuest LLC, Ph.D. Dissertation, University of Illinois at Urbana-Champaign
How do you dynamically customize the programming language available in a context within an existing system, without changing the underlying system? This dissertation introduces a language design approach that addresses this problem. The basic idea is to structure programs as systems of multiple interacting levels of abstraction, where all of the primitive constructs used by higher levels are actually implemented as defined constructs by lower levels. This is accomplished by allowing lower levels to mediate the execution of higher levels. This structure is much like system-level virtualization, but much finer-grained. The approach builds on three existing programming language technologies: delimited continuations, dynamic scoping, and call-by-name nonstrict evaluation. The dissertation examines how to define a variety of different language constructs using this approach, including variable binding, control structures, and basic concurrency features. The approach is then applied to mediating execution of third-party Javascript code on web pages. [The dissertation citations contained here are published with the permission of ProQuest LLC.
