Update on what happened in WebKit in the week from April 7 to April 14.
Cross-Port 🐱
It is now possible to customize the limit of the content resources kept for the network page of WebInspector.
Reduce the amount of data kept for network page of WebInspector after eviction in case the memory limit is exceeded.
Multimedia 🎥
GStreamer-based multimedia support for WebKit, including (but not limited to) playback, capture, WebAudio, WebCodecs, and WebRTC.
On the WebRTC front, basic support for Rapid Synchronization was added, along with a couple of spec coverage improvements (https://commits.webkit.org/293567@main, https://commits.webkit.org/293569@main).
Fixed some upstream regressions in OMG.
Dispatch a "canceled" error event for all queued utterances in case of SpeechSynthesis.
Support for the Camera desktop portal was added recently, it will benefit mostly Flatpak apps using WebKitGTK, such as GNOME Web, for access to capture devices, which is a requirement for WebRTC support.
JavaScriptCore 🐟
The built-in JavaScript/ECMAScript engine for WebKit, also known as JSC or SquirrelFish.
Fixed a corner case in BBQJIT.
Work continued on porting the in-place wasm interpreter (IPInt) to 32-bits.
We have been working on bringing the Temporal implementation in JSC up to the current spec, and a step towards that goal was implemented in WebKit PR #43849. This PR changes how calendar annotation key parsing works; it doesn't change anything observable, but sets the groundwork for parsing calendar critical flags and unknown annotations.
Releases 📦️
The recent releases of WebKitGTK and WPE WebKit 2.48 introduced a number of improvements to performance, reduced resource usage, better support for web platform features and standards, multimedia, and more!
Read more about these updates in the freshly published articles for WebKitGTK, and WPE WebKit.
Community & Events 🤝
Support for Display device permission requests was recently added in GNOME Web, this is a requirement for Screen Capture handling on the User-Agent side.
Pawel Lampe published a blog post on the damage propagation feature. This feature reduces browser's GPU utilization at the expense of increased CPU and memory utilization in the WPE and GTK WebKit ports.
Our efforts to bring GstWebRTC support to WebKitGTK and WPEWebKit also include direct contributions to GStreamer. We recently improved WebRTC spec compliance in webrtcbin, by making the SDP mid attribute optional in offers and answers.
That’s all for this week!
