mrobinson@igalia.com 2 days ago

Done:

  • Investigating how to fix layered content underneath unlayered content in Servo.

Next:

  • Land the aforementioned PR.
  • Deal with StackingContexts that have layered children.

pcwalton@mozilla.com 7 months ago

Done:

Last week:

  • Some business development on Monday and Tuesday.
  • Started work on a Rust audiovisual codec library with the goal of using it for animated GIFs, video, and audio in Servo.
    • Created Cargo packages for unencumbered codecs and container formats: MP4 (via mp4v2), Vorbis, WebM, and VP8.
    • Implemented bindings for the Mac VideoToolbox and AudioCodec framework and the Linux FFmpeg library so that we can decode H.264 and AAC if the end user has the appropriate decoding libraries installed.

Next:

  • More work on rust-media:
    • Implement support for animated GIFs in rust-media via giflib.
    • Generalize the support for the Mac AudioCodec framework. Right now it is hardcoded to 48000 bps and 6 channels; it needs to find the bitrate and channels from the media stream itself.
    • Implement AAC audio support on Linux by binding to the system FFmpeg (if available).
    • Implement streaming support.
    • Test rust-media with a sample SDL-based app that plays H.264 and WebM video.
    • Land rust-media as a dependency of Servo.
  • Servo, more generally
    • Follow up on reviews, especially for sandboxing.

cgaebel@mozilla.com 11 months ago

Done:

  • Lots of incremental layout work
    • sibling selectors are a thing, so mark siblings of a dirty node are also dirty
    • Word wrapping bug in incremental layout fixed
    • Fixed the bug where wikipedia elements drift down the page
    • Fixed the bug where freshly loaded images wouldn't trigger a reflow
    • Implemented incremental reflow (before it was just incremental style recalc).

Next:

  • Fix all the bugs with incremental reflow. There's some failing reftests, and I can't seem to be able to remove an image in javascript without having to resize the page to make it disappear...
  • Implement incremental display list sending.

Next:

Land control-flow graph visualization library with libgraphviz.

Attempt to clean up control-flow graph code and land it too.

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?)

alex@crichton.co last year

Done:

  • Forbid unnecessary privacy in functions - #10111
  • Optimize tty usage in libuv (stdout mostly)
  • Implemented unstable::mutex::Mutex to remove all remaining C++ synchronization code
  • Landed the native file I/O patch
  • Re-worked privacy/reachable to put more work in privacy (where it belongs)
  • Removed linked failure

Next:

  • Get a review for the static linking patch
    • Once static linking is landed, get a libcxxabi/libunwind solution for windows
  • Rewrite channels to be much more optimized and work inside/outside the runtime
    • Drop oneshot, possibly drop SharedPort
  • Once channels are rewritten, add a convenient way of booting the runtime
  • Continue supporting 1:1 by overhauling task creation

Coordination:

I'll be in SFO all week, taking Wed-Fri off.

catamorphism@gmail.com last year

tchevalier@mozilla.com

Done:

Landed #7419 (making rustpkg build work without a package argument) Started #7075 (using workcache) -- got blocked on workcache context not being sendable. Graydon did some work on it and it should be possible for me to get back to this if that work has landed. Worked on #6407 (allowing extern mods to name a URL) Debugged sporadic rustpkg test failures on the Mac bot; currently making check-rustpkgtest depend on the rustpkg executable, which I'm hoping will fix it

Next:

Finish #6407 Finish #7075 Implement #6411

Coordination:

Working remote on Thursday and Friday (doctor's appointment on Thursday, heading to SF office for Feminist Friday).
