By combining APIs, code, and ideas from [http://lxr.mozilla.org/mozilla/source/js/src SpiderMonkey] and [http://lxr.mozilla.org/mozilla/source/js/tamarin Tamarin], we will build a [http://developer.mozilla.org/es4 JS2] virtual machine as part of Mozilla 2.

The Tamarin code contribution is a big boost to this effort, and we intend to extend it, not copy code from it. But we need more than today's Tamarin in order to avoid certain pitfalls. We will probably need all of these: | ||

Current DOM security checks use the [[Security:Scattered Security Checks]] model. For Mozilla 2, in order to JIT DOM calls efficiently, we need either [[Security:Security Checks In Glue]] or [[Security:Wrapper-based Checks]]. To support "mashups in the browser" and [http://www.w3.org/TR/XBL XBL2], we may need to support data-tainting with static flow analysis as well as dynamic taint propagation. | Current DOM security checks use the [[Security:Scattered Security Checks]] model.
