Advisor Name Title Back, Godmar V. Committee Chair Ryder, Barbara G. Committee Member Tilevich, Eli Committee Member Keywords
- Resource Control
- Web Browsers
We implemented a prototype of ScriptSpace based on the Firefox 3.0 browser. Rather than mapping ScriptSpaces to OS-level threads, we exploit a migrating-thread model in which threads enter and leave the ScriptSpaces associated with the respective sections of the document tree during the event dispatching process. A proportional share scheduler ensures that the number of bytecode instructions executed within each ScriptSpace is controlled. Our prototype can isolate resource-hogging gadgets within an iGoogle Mashup page as well as across multiple pages loaded in the browser and still retain interactive response.
