Request for position: Critical-CH response header, part of Client Hints Reliability proposal
by Aaron Tagliaboschi 29 Jan '21

Explainer: https://github.com/WICG/client-hints-infrastructure/blob/master/reliability… Draft Spec: https://tools.ietf.org/html/draft-davidben-http-client-hint-reliability-02#… The Client Hint Reliability proposal is a set of features aimed at making Client Hints <https://tools.ietf.org/html/draft-ietf-httpbis-client-hints-15> more reliably available and mitigating mis-matches between a site's preferences and the preferences stored in the browser. The idea behind the Critical-CH response header is to signal to browsers that there are hints the server would rather pay a round trip than not have not the first request. The basic algorithm is as follows: If, after receiving a request with Critical-CH and Accept-CH headers, there is a hint indicated in the Critical-CH header that the browser did not send but would not block sending, the browser should store the new CH preferences, drop the request, and start a new one with the new headers included.

Request for position on import maps
by Domenic Denicola 21 Jan '21

21 Jan '21

Hello webkit-dev, For the last couple of years myself some other Chrome folks have been working on the import maps proposal. This allows controlling the behavior of JavaScript import statements and import() expressions, in particular by allowing the page to customize the translation of the module specifiers used there into URLs. Developer reception of the feature has been very positive, with continual prompting for when it'll be widely available in more browsers, and a plethora of community-created tools and polyfills. Chrome is working toward shipping this in an imminent release, and we'd love any thoughts or contributions from the WebKit community. Relevant links: * Explainer: https://github.com/WICG/import-maps/blob/master/README.md * Spec (would eventually merge into HTML upon multi-implementer interest): https://wicg.github.io/import-maps/ * Test suite: https://github.com/web-platform-tests/wpt/tree/master/import-maps/ (although getting rearranged a good bit in https://github.com/web-platform-tests/wpt/pull/26239 ) * Mozilla standards position discussion, with lots of web developers contributing: https://github.com/mozilla/standards-positions/issues/146 * Some gathered evidence of developer interest: https://github.com/WICG/import-maps#community-polyfills-and-tooling Thanks for your time! -Domenic

Position on WebXR dynamic viewport scaling
by Klaus Weidner 12 Jan '21

12 Jan '21

[+Dean Jackson since it's WebXR related] Hello WebKit, I'd like to ask for WebKit's position on the dynamic viewport scaling feature that's part of the WebXR API. This is intended to let applications render to a subset of the full viewport and adjust that scale on a per-frame basis if needed to reach target framerates. Specification: Part of WebXR, see for example https://immersive-web.github.io/webxr/#dom-xrview-requestviewportscale Explainer: https://github.com/immersive-web/webxr/blob/master/explainer.md#dynamic-vie… TAG review request: https://github.com/w3ctag/design-reviews/issues/588 This was discussed in https://github.com/immersive-web/webxr/issues/1091 and multiple calls with the immersive-web group. The changes were merged into the main specification via https://github.com/immersive-web/webxr/pull/1132 , but to the best of my knowledge this hasn't been launched in any other browser yet. Could I get your position on this? For context, the goal is that this API is optional for UAs. It would be a valid implementation to provide a requestViewportScale method that does nothing. If it is supported, the UA can optionally provide a recommendedViewportScale numeric attribute based on internal heuristics, but it's also valid to keep that undefined. Thank you, Klaus Weidner

Official GitHub Mirror Automatically Syncing
by Jonathan Bedard 07 Jan '21

07 Jan '21

Hey folks, Just wanted to let everyone know that our GitHub mirror, https://github.com/WebKit/WebKit <https://github.com/WebKit/WebKit>, is being automatically updated on SVN commits to trunk, just like the git.webkit.org <http://git.webkit.org/> repositories. Using the GitHub repository for daily development or automation is now considered a supported workflow. At this point, the history of main will remain unchanged, so the hashes of the commits along main in https://github.com/WebKit/WebKit <https://github.com/WebKit/WebKit> will not be changing. If you haven’t done so already, now is a good time to set up a GitHub account and ensure the emails you have used to commit to WebKit are attached to that account.
