Additional Apple Internal EWS status-bubbles on some WebKit PRs
by Aakash Jain 05 Aug '25

Hi All, You may notice additional EWS status-bubble column named "Apple Internal" appearing on some WebKit GitHub pull requests. These builds correspond to Internal builds that are automatically triggered for a subset of PRs. These are available only for certain contributors. If you don’t see them on your PRs, that’s expected and there’s no action needed on your part. Thank you for your continued contributions! -Aakash

InjectedBundle deprecation
by Alex Christensen 01 Aug '25

01 Aug '25

Hello WebKit developers! We are ramping up to do some serious work on Site Isolation which includes putting cross-origin iframes in a different process than the parent frame. Similar efforts have been done in other browser engines and some related work has already been done in WebKit, but not enough. This will do strange things to the InjectedBundle APIs, which have fundamental assumptions that the whole DOM is in one process and that communication only happens with one process at a time. We have never exposed InjectedBundle APIs as public API, but some other distributors of WebKit have. As we make progress on this project, we anticipate that anything in Source/WebKit/WebProcess/InjectedBundle/API is subject to deprecation and removal. This will also allow us to tighten the sandbox on the web process, resolve security and performance issues, and have cleaner code. Would the maintainers of the GTK and WPE APIs be willing to assist in migrating from those APIs and designing replacements in the UI process? Alex Christensen

Site isolation
by Alex Christensen 01 Aug '25

01 Aug '25

The SiteIsolation feature is beginning to work in the simplest of cases, but I had to do some work in the Source/WebKit/Shared/RemoteLayerTree directory, which is platform-specific. Basically all the use of LayerHostingContextIdentifier in that directory needs an equivalent implementation for other graphics implementations, like in the CoordinatedGraphics directories. There is one layout test in LayoutTests/http/tests/site-isolation/basic-iframe.html that is currently skipped on all non-Cocoa platforms. Is someone willing to collaborate to design and implement the feature in non-Cocoa ports? We are in the early stages of the project and have a long way to go, so I imagine things will continue to come up, like deciding how to implement event handling and other platform dependent features.
