tschneidereit@mozilla.com 4 months ago

Done:

Since my last update last year, I mostly worked on the SpiderMonkey Promise implementation. That has landed in SpiderMonkey, but not been enabled for Gecko's use. Some additional patches for devtools and Xray wrappers need to land for that.

Additional work:

  • Re-implemented Function.prototype.bind in self-hosted JS, gaining several-10x speed-ups for the most common usecases in bug 1000780.
  • Continued work on the Typed Objects Explainer, incorporating most discussion results into the core explainer and adding more fleshed-out drafts of explainers for value types and class syntax.
  • Let Object.values and .entries ride the train, after porting them from JS to C++ :(

Also, I officially joined the browser.html team \o/

Next:

  • Finish SpiderMonkey Promise.
  • Integrate Promises into Servo's event loop as soon as nox' SMUP work is done.
  • Deepen my understanding of browser.html.
  • Get back into Servo work, now with a focus on browser.html blockers.

nox@mozilla.com 4 months ago

Done:

  • Asked questions around #devtools, got a meeting out of it on 2016-04-07 with some devtools people
  • Continued to do SMUP, not many errors, might get a successful build of rust-mozjs soon.

Next:

Continue the aforementioned things.

aramine@mozilla.com 4 months ago

  • Continue unforking of rust-bindgen

Coordination:

  • I will probably need to mess with compartments and whatnot for object grips in devtools. Will ask bholley for help.

mrobinson@igalia.com 8 months ago

Done:

I've been working on making sure that RestyleDamage is less "sticky" when applied to the flow tree. This is useful because it will allow us to more closely track when the tree is actually damaged, allowing fast paths during reflow.

Next:

I've been able to isolate certain types of repainting to one part of the tree. Now I need to continue to experiment with this to see if I can make very, very simple display list patches. This will allow us to patch the display list very quickly for a small subset of operations that do now reflow the tree at all.

After that, I need to extend this optimization to include things that actually reflow the tree.

Continue work on lifetime bounds (namely supporting constructs like ~Foo:'a and trait Bar<'a> : 'a { ... }).

Coordination:

Regarding make check-stage1: I am not sure if we could possibly turn it on in buildbots.

Alex said we probably cannot guarantee that make check-stage1 always works for arbitrary desired changes. Is there some middle ground, like having bors run make check-stage1 and write a note in any PR where it fails?

I.e. so that it doesn't block landing work, but contributors are at least informed that it is not working? (And might have a hope of tracking down when it started failing in previous PRs that landed?)
