WebKit VS xdg-desktop-portal

Since 2023 Chrome announced the View Transition API, and it looks like Safari is also going to support it soon.

One heap per type.

Here’s an allocator optimized for that use case.

https://github.com/WebKit/WebKit/blob/main/Source/bmalloc/li...

To use this in Bun, you’d have to start Bun with the environment variable “BUN_JSC_useDollarVM=1” and then $vm.createBuiltin(mySourceCodeString)

When using this intrinsic, if any of the arguments are incorrect or it cannot otherwise enable it, the entire process will probably crash. In debug builds of JSC it will have a nicer assertion failure but that is not enabled in release builds

Example code: https://github.com/WebKit/WebKit/blob/17351231b4dedb62d81721...

also happy to answer any questions about Bun

Ah, good, let me introduce you to the wonderful world of the Chrome Devtools Protocol! (fka Chrome Remote Debugging Protocol)

I love this API for almost everything browser related. I built my RBI product atop this (BrowserBox: https://dosyago.com), and I think it's a drastically underrated API.

Also, it works out of the box in Edge, Brave, Chromium, and many parts of CRDP are supported by Firefox and Safari^1

1: See for example: https://github.com/WebKit/webkit/tree/main/Source/JavaScript...

No, it's unrelated.

It's being worked on now: https://github.com/WebKit/WebKit/pull/17320

It is different. The cross-site navigation flag is a couple of years old. It was enabled by default for iOS in November 2018 for example https://github.com/WebKit/WebKit/commit/e191fc8c412850cb9fd0...

> That's excessive scope creep. Adding site-specific workarounds for some sites feels uncomfortable.

Not to Google and its fellow corporations apparently.

They have site-specific fixes for their own sites. Why can obviously apply the exact same strategy to dealing with every single website out there. If a website is broken or generally annoying to use, just fix it by providing a site specific version of the browser.

> Who decides what websites get "fixed", and how?

Whoever develops the browser or its extensions. Arguably the whole of uBlock Origin and its filter lists is just a database of site specific fixes. If people can maintain an extremely huge list of advertisers and blockers for every website out there, surely they can maintain something like this too.

> Also, remember how Mozilla is funded.

I remember Mozilla has about a billion dollars in the bank. Who cares about their Google funding? I doubt they're gonna drop them anyway. I bet they pay them just to ward off risk of antitrust lawsuits.

Up to the compositor.

>Global shortcuts

Also up to the compositor. Was added to xdp in https://github.com/flatpak/xdg-desktop-portal/blob/main/data... so it's up to the compositor's xdp impl to provide it. It was created by a KDE dev so I assume KDE implements it at least.

Works just fine. I use OBS.

Never had any trouble with it.

> - No proper global keyboard shortcut

> - No push to talk support

Haven't had any more than on X11, but then again I do use Nvidia hardware on Linux.

It might help, but at this point Linux containers can't really stabilize the whole environment, especially for games. Particular pain points include accelerated graphics (which theoretically can have a stable kernel interface, but in practice is so complex and performance-sensitive that it's not stable enough to be a "reference platform", so to speak) and modern game controllers (which present a whole mess of concerns typically "addressed" in Flatpak by granting the device=all permission and hoping for the best [1]).

I also know a guy who ran into issues with a kernel update breaking a custom allocator, although I don't know the fine details. That wasn't for a game, but games also use custom allocators for various reasons.

I don't use Wayland, but it seems xdg-desktop-portal since 1.16.0 has a 'Global Shortcuts portal'. Perhaps check it out.

It's being discussed: https://github.com/flatpak/xdg-desktop-portal/issues/611

The first bug report was filed in early 2022 but unfortunately no progress yet on the matter, even after numerous similar reports ever since.

Yeah been having the same issue since I changed to using the unstable branch, supposedly noticed and fixed upstream for a few variants of the problem (different people with different configurations of DE and xdg-* deps installed report the same issue due to timeouts of the other portals)
