Quantumdom

If we ran F1, F2, F3 before the other runnables, then we would run F's events out of order (since F3 would run before F2.5). To get started, check out the rust-bindgen contributing guide and bugs tagged on GitHub as “easy” bugs. The easiest way to get involved in the Quantum project is to dive into one of the projects listed below, to help us writing code, running tests and filing bugs. We can modify this code to save an event target while still on the main thread, storing it in the runnable, and then dispatching to that event target off the main

Build awesome stuff faster. A: This can be done by nsITimer::SetTarget(nsIEventTarget*) combined with EventTargetFor. In some preliminary experiments we’ve done, it looks unlikely that we’ll be able to increase the number of content processes beyond 8 in the near future; any more processes will increase Generated Wed, 22 Feb 2017 17:40:56 GMT by s_hp102 (squid/3.5.23)

Namespaces should be omitted as before unless they're necessary. Quantum is roughly divided into four distinct projects. Assume that X is an unlabeled runnable dispatched using NS_DispatchToMainThread. While the project has evolved somewhat since then, Servo has heavily influenced the design.

  • To have a name, a runnable needs to implement the GetName method of the nsINamed interface.
  • Servo uses the GPU more effectively than Gecko does, driving it more like a game would than a browser.
  • We’re still working out the heuristics that we’ll need to identify important background tabs.

The IPC code, for example, can set the runnable name to the name of the message being dispatched.

Quantum is Mozilla's project to build the next-generation web engine for Firefox users, building on the Gecko engine as a solid foundation. This requires familiarity with Rust, but is otherwise a good way to dip your toes into Servo's style system. First, a TabGroup is the set of tabs that are related by window.opener. Like Servo and Rust, the unifying themes of Quantum are increased concurrency and parallelism, reduced latency, and better reliability.

DocGroups are essentially a refinement of TabGroups to account for the fact that only same-origin documents can synchronously communicate. (The eTLD+1 part is to account for pages changing their origin by Join our site today to ask your question. Quantum uses rust-bindgen to generate the glue code between Firefox’s C++ code and Servo’s Rust components.

Michael Layzell is building a “DocGroup” abstraction so that same-origin frames that can talk to each other, either via window.parent or window.opener, will run on the same thread (bug 1303196). Example already_AddRefed WebAuthentication::MakeCredential(JSContext* aCx, const Account& aAccount, const Sequence& aCryptoParameters, const ArrayBufferViewOrArrayBuffer& aChallenge, const ScopedCredentialOptions& aOptions) { MOZ_ASSERT(mParent); nsCOMPtr global = do_QueryInterface(GetParentObject()); if (!global) { return nullptr; } ... // lots The system returned: (22) Invalid argument The remote host or network may be down. The IPC code allow you to specify an event target for each actor.

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 Ehsan Akhgari is doing some exploratory work and we’re hoping to land some experiments on Nightly soon.

Runnable names One disadvantage of using EventTargetFor is that any runnables dispatched this way are not given a name. Only use the system group if you know that the runnable will not run any content JS code or do any content DOM or layout access. learn more james.smyth published 2016-04-25T11:57:31.581Z 0.0.0 is the latest release Apache-2.0 ® Collaborators list Stats 3 downloads in the last day 5 downloads in the last week 10 downloads in the

We have already begun experimenting with this sort of switching.

In these cases it's best to modify the sub-system to set pass down an appropriate name for the runnable. The nsIGlobalObject::Dispatch method is main thread only. RefPtr dispatcher; if (doc) { dispatcher = doc->GetDocGroup(); } else { // Top-level loads won't have a DocGroup yet. These projects are in varying stages of completeness.

If a runnable on a background thread takes too long to run, then we will pause its execution and switch to a different thread. Some Stylo bugs that are good for new Servo contributors are tagged on GitHub as “easy” bugs and “less-easy” bugs. This entry was posted in Uncategorized. Quantum Compositor The Quantum Compositor moves Gecko’s compositor into its own process.

Well, X could be an F runnable (so maybe X = F2.5). But labeling other runnables won't break anything. As the project progresses, we will evaluate whether OS threads make sense for us. AbstractThread::MainThread AbstractThread::MainThread() is a singleton of the AbstractThread wrapper class for the main thread and is widely used with MozPromise and its Promise-chain.

If you're interested in contributing to Quantum or Servo, drop by: the #quantum or #servo IRC channels on Mozilla's IRC server the dev-quantum mailing list the mozilla.dev.quantum NNTP newsgroup The Servo The Quantum CSS project will replace Gecko’s CSS engine with the one from Servo. Firefox already throttles some background work, like setTimeout tasks, to run at most once per second. The Stylo hacking guide also has instructions for building Stylo if you wish to play with it yourself.

Bug 1279086, landed in Firefox 51, allows us to pause JavaScript execution so that we can paint during a tab switch. Please try the request again.
