JavaScript:ActionMonkey

ActionMonkey is the code-name for the project to integrate Tamarin and SpiderMonkey as part of Mozilla 2.

Goals

The goals are:

• Preservation (with necessary additions and as few deletions as possible) of jsapi.h.
• SpiderMonkey's thread safety and property tree integrated/reimplemented in Tamarin.
• Replacement of SpiderMonkey's decompiler with a better decompiler that can work with ABC.
• Replacement of SpiderMonkey's GC with Tamarin:MMgc, evolved as needed.
• Replacement of SpiderMonkey's interpreter by an evolved version of Tamarin's.
• Advanced JIT optimization for hot paths and untyped code, inspired by Trace Trees.
• Information flow VM support for better security models.

Stage 0

Replace SpiderMonkey's GC with Tamarin's GC (MMgc). See JavaScript:ActionMonkey:Stage 0 Whiteboard.

Work is underway in the http://hg.mozilla.org/actionmonkey and http://hg.mozilla.org/actionmonkey-tamarin Mercurial repositories. (The actionmonkey repo is a hard hat area, one step removed from the primary mozilla-central repository. This is because we expect things will break intermittently. Also because some of the people working on this aren't CVS committers yet, myself included. -jorendorff)

Stage 1

More to come.
