Update on what happened in WebKit in the week from November 3 to November 10.
This weeks brought a hodgepodge of fixes in Temporal and multimedia, a small addition to the public API in preparation for future work, plus advances in WebExtensions, WebXR, and Android support.
Cross-Port 🐱
The platform-independent part of the WebXR Hit Test Module has been implemented. The rest, including the FakeXRDevice mock implementation used for testing will be done later.
On the WebExtensions front, parts of the WebExtensionCallbackHandler code have been rewritten to use more C++ constructs and helper functions, in preparation to share more code among the different WebKit ports.
A new WebKitImage utility class
landed this week. This image
abstraction is one of the steps towards delivering a new improved API for page
favicons, and it is also expected to
be useful for the WebExtensions work, and to enable the webkit_web_view_get_snapshot()
API for the WPE port.
Multimedia 🎥
GStreamer-based multimedia support for WebKit, including (but not limited to) playback, capture, WebAudio, WebCodecs, and WebRTC.
Videos with BT2100-PQ colorspace are now tone-mapped to SDR in WebKit's compositor, ensuring colours do not appear washed out.
Lots of deadlock fixes this week, one among many in the MediaStream GStreamer source element.
Video frame rendering to WebGL was fixed. Another pending improvement is GPU-to-GPU texture copies, which might be coming soon.
JavaScriptCore 🐟
The built-in JavaScript/ECMAScript engine for WebKit, also known as JSC or SquirrelFish.
JavaScriptCore's implementation of Temporal received a number of improvements this week:
-
Fixed a bug that would cause wrong results when adding a duration with a very large microseconds or nanoseconds value to a
PlainTime. -
Fixed a rounding bug of
Instantvalues. -
Fixed a bug that resulted in incorrect printing of certain
Instantvalues before the Epoch. -
Fixed a bug that resulted in wrong results instead of exceptions when a date addition operation would result in an out-of-range date.
WPE WebKit 📟
WPE Android ↗ 🤖
Adaptation of WPE WebKit targeting the Android operating system.
One of the last pieces needed to have the WPEPlatform API working on Android has been merged: a custom platform EGL display implementation, and enabling the default display as fallback.
Community & Events 🤝
The dates for the next Web Engines Hackfest have been announced: it will take place from Monday, June 15th to Wednesday, June 17th. As it has been the case in the last years, it will be possible to attend both on-site, and remotely for those who cannot to travel to A Coruña.
The video recording for Adrian Pérez's “WPE Android 🤖 State of the Bot” talk from this year's edition of the WebKit Contributors' Meeting has been published. This was an update on what the Igalia WebKit team has been done during the last year to improve WPE WebKit on Android, and what is coming up next.
That’s all for this week!
