Notices
GFX 1.9.1 Update
- GFX blocking 1.9.1+
- vlad finishing up border work, need to find machine to reproduce perf problems
- GFX wanted 1.9.1+
- SVG fonts
- karlt: no progress due to distractions. This will benefit from the infrastructure being developed for downloadable fonts.
- Do we have an update on bz's work to make <img src="foo.svg> possible?
- SVG fonts
- Video (roc/cdouble)
- Core element patch uploaded, needs content review now, hopefully land soon
- Some tests written, still working on them
- Ogg Vorbis/Theora backend could get review soon after core element patch lands
- Probably should try to land GStreamer and Quicktime backends soonish
- DirectShow backend playing some movies, needs more work
- downloadable fonts (jdaggett)
- unified font entry in this week hopefully (bug 437356)
- starting on user font object (bug 441473)
- zack: @font-face parsing is coded, but does not populate any data structure yet; am planning to make it build a standard CSS DOM structure; the user font set object should then populate from that; see bug 441469 for details
- roc: this (and SVG fonts) seem most at risk; hard to see it working by end of July
- jdaggett: SVG fonts is a much bigger task than downloadable fonts (parsing, external refs, shaping, drawing, etc.)
- pixman/cairo perf (vlad):
- Will do new drop of cairo in next 2 weeks
- Will have SSE2 opts and additional work from antoine/fred
- 16.16 pixman coordinate space still an issue
Layout 1.9.1 Update
- 1.9.1 Layout Bugs
- Acid3: Roc or dbaron, status?
- Nothing much happening, lots of patches waiting for review (dbaron, bz, jonas)
- SMIL still @ risk? (dholbert)
- May not have a 100% complete implementation, but we should have a good subset implemented in time for feature freeze
- Currently working on integrating with style system to animate CSS properties
- SVG fonts at risk?
- karlt: yes.
- SVG CSS, roc:
- Patches trickling into trunk, need review mats immediately and will need reviews from mats and rlongson and others for ongoing merging
- SVG gradients and patterns as backgrounds for HTML elements --- working in branch
- Starting work on feature to use an element as background for another element (covers -webkit-canvas, (combined with transforms) reflections, thumbnails and other use cases), should be quick as infrastructure is in place
- white-space:pre-line (roc)
- needs review
- box-shadow (Ventnor)
- Style system changes need review dbaron, rest ready to land
- CSS transforms - keith:
- Parser can read -moz-transform property. Working on helper -moz-transform-origin property.
- Basic rendering works (e.g. can draw all transforms). Need to work on computing overflow rectangles.
- Working on mouse interaction and click detection.
Content 1.9.1 Update
- Content 1.9.1 Bugs
- ~30 wanted bugs, needs triaging. Nothing critical for alpha1 on the list from first look.
- Worker Threads, bent, status?:
- Ben will work on getting worker threads code split into reviewable patches. Basic message passing, start/pause/resume/cancel, and (mostly) timers working so far. Once that's done he'll continue with what's left. Most recent WIP patch in bug 437152.
- Spec about ready for general consideration. Arun to arrange meetings with Gears folks, others.
- DOM worker thread XHR (minus the 'X') not yet started.
- Tab reparenting (bz), at risk for 1.9.1? [I'm hoping to get some work done on this in the two weeks starting July 7. We'll see how well that works and whether it's enough. I think it might well be. --Bzbarsky]
- Cross-site XHR, at risk for 1.9.1? What's the current status on the spec and us internally agreeing on what to do?
- Jonas in Redmond this week with Arun discussing how to proceed here.
- Critical plugin infrastructure bugs ready to land (reviews pending).
