411563 - ActionMonkey stage 2 tracking bug

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine, defect)

Description

[Jason Orendorff [:jorendorff]]

The theme of this stage is incremental GC for Mozilla.

We'll make incremental GC thread-safe and implement features needed by XPCOMGC.

Another possible source of work is a whole new memory management system treilly wants to use in place of MMgc.  I'm not opposed, but it sounds like a lot of work to make another allocator thread-safe.

More info will be available after 1 Feb 2008, as Adobe is hosting a Tamarin summit in San Francisco and this is on the agenda.

The new memory management system, "spam", is not suitable for desktop platforms.  We'll stick with MMgc for now.

We need pluggable memory management for Tamarin.  Right now, I gather, treilly has landed something that uses macros, duct tape, and baling wire to allow TT to build with either MMgc or spam.  I hope we can make this abstraction layer "real" and later, when we're ready, slide in jemalloc++ to replace MMgc.
