To get started, see Servo's CSS property hacking guide for more information. We can add a SetTimerEventTarget method that dispatches timers to the correct DocGroup: void XMLHttpRequestMainThread::SetTimerEventTarget(nsITimer* aTimer) { if (nsCOMPtr global = GetOwnerGlobal()) { nsCOMPtr target = global->EventTargetFor(TaskCategory::Other); aTimer->SetTarget(target); } } When In a session with four tabs, where T1 opens T2 and T3 opens T4, the TabGroups are {T1, T2} and {T3, T4}. AddIPDLReference(); PBrowserOrId browser = cc->GetBrowserOrId(tabChild); if (!gNeckoChild->SendPHttpChannelConstructor(this, browser, IPC::SerializedLoadContext(this), openArgs)) { return NS_ERROR_FAILURE; } Actors constructed by the parent If the new actor is created on the parent side, normally, it

That's good. You need to specify the event target after the actor is created but before sending the constructor message to the parent process. Concepts To more precisely specify when one runnable can observe state from another runnable, we need to define some terminology. rust-bindgen rust-bindgen is a C++ bindings generator for the Rust language.

Typically you'll be giving the event target to a sub-system that will dispatch multiple runnables.

Runnables that do not affect web content can be labeled with the SystemGroup. And you want Gmail to notify you that an email has arrived even when the Gmail tab isn’t selected. Mozilla developers are working to reduce the memory overhead of a content process, but we will never be able to reduce the overhead to zero. Rasmus Fløe @rasmusfl0e "Quantum DOM" might not be the best name ever; as soon as you read state it changes? But otherwise it sounds good:D google.dk/amp/s/billmccl… 12:21 AM - 15 Nov 2016 Mozilla’s

Assume that the F runnables are for the foreground tab and the B runnables are for a background tab. Advertisements do not imply our endorsement of that product or service. If you use AbstractThread::MainThread() in your code and you have access to a document or a window, you can replace it with AbstractMainThreadFor provided the document or window object (or by Quantum Flow The Quantum Flow project will explore performance improvements not covered by the other Quantum components, such as UI optimizations.

The Quantum CSS project will replace Gecko’s CSS engine with the one from Servo. The downside of threads is that all this shared data needs to be protected with locks. That's bad. plz) 1296400 P2 Remove support for windowed mode plugins must wait to drop non-Flash plugins dev-doc-needed, site-compat Benjamin Smedberg [:bsmedberg] 1325171 P3 Firefox visual refresh Stephen Horlander [:shorlander] 1274659 P3 Migrate

  1. But if the runnable is mozilla::dom::OffThreadScriptRunnable, then the namespaces can be omitted.
  2. So if a TabGroup contains tabs with documents {x.a.com, y.a.com, x.b.com, y.b.com}, then these documents will belong to two DocGroups: {x.a.com, y.a.com}, {x.b.com, y.b.com}.
  3. Therefore we could run F1, F2, F3 before any other runnables.
  4. See the Stylo hacking guide for more details.
  5. Quantum was originally conceived to integrate technology from our Servo research browser into Gecko.

Threads are nice because they can share address space, which makes it much easier to share data. While the project has evolved somewhat since then, Servo has heavily influenced the design.

We and our partners operate globally and use cookies, including for analytics, personalisation, and ads. But for some runnables the best we can do is to give it a TabGroup. For example, you want Pandora to continue to play even when you switch away from it. Quantum Compositor The Quantum Compositor moves Gecko’s compositor into its own process.

In these cases it's best to modify the sub-system to set pass down an appropriate name for the runnable. See the video of Jack Moffitt’s Web Engines Hackfest presentation for a preview of some of the Servo components that will be integrated into Firefox. Telemetry shows that, as a consequence, the number of long (> 300ms) tab switches has been cut in half. The Dispatch method requires you to name the runnable and provide a "task category".

Before we can do that, we need to “label” all the tasks in our event queue with the iframe that they correspond to. However, before we can run F3, we need to run B1, B2, and X. plz) 1335518 -- [meta] tracking work to collect code coverage for Rust code 1302270 -- Responsiveness improvements in DOM meta, perf 1207306 -- Ship Firefox with multiple content processes [DevRel:P2] DevAdvocacy,

If a runnable on a background thread takes too long to run, then we will pause its execution and switch to a different thread.

As our infrastructure for labeling improves over the next few weeks, task labeling will be a great place for contributors to help with the project. Goals The goal of the Quantum DOM project is to eliminate jank caused by background tabs. billmccloskey.wordpress.com/2016/10/27/moz… 12:28 PM - 27 Oct 2016 Mozilla’s Quantum Project A few months ago, Mozilla began a project to make significant changes to our Gecko rendering engine to make it faster Only content process runnables need to be labeled.

Otherwise, the benefit we get from Quantum-DOM will be significantly reduced. See the XMLHttpRequest example above.

Build awesome stuff faster. In that case, we have a lot of freedom about when to schedule it. Given a document, you can find its DocGroup via nsIDocument::GetDocGroup. To do so, call the SetEventTargetForActor on the manager of the new actor.
