LibWeb: Add all HTML elements between S and V
2020-08-01 03:07:00 +01:00
/*
Everywhere: Use "the SerenityOS developers." in copyright headers We had some inconsistencies before: - Sometimes "The", sometimes "the" - Sometimes trailing ".", sometimes no trailing "." I picked the most common one (lowecase "the", trailing ".") and applied it to all copyright headers. By using the exact same string everywhere we can ensure nothing gets missed during a global search (and replace), and that these inconsistencies are not spread any further (as copyright headers are commonly copied to new files).

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

WEB_PLATFORM_OBJECT(HTMLSourceElement, HTMLElement);
LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibWeb: Move QualifiedName into the Web::DOM namespace
2022-02-18 21:00:52 +01:00
HTMLSourceElement(DOM::Document&, DOM::QualifiedName);
LibWeb: Move setting of Web object prototypes to initialize() This needs to happen before prototype/constructor intitialization can be made lazy. Otherwise, GC could run during the C++ constructor and try to collect the object currently being created.

LibJS: Make Cell::initialize() return void Stop worrying about tiny OOMs. Work towards #20405

LibWeb: Partially implement HTMLSourceElement's insertion/removal steps This implements the substeps which concern HTMLMediaElement parents.

LibWeb: Pass better information to node moving/removing steps Corresponds to: https://github.com/whatwg/dom/commit/73de9e5e1bfe581397d58d0b10b4da448d973c8a https://github.com/whatwg/html/commit/097be9feaa65bf405046356724f480266d35ca8e

LibWeb: Re-evaluate picture source set on source mutations The img inside a <picture> has to re-run "update the image data" when nearby <source> elements change, so script-driven swaps of srcset (and the other dimension/media attributes) actually take effect. Per the HTML spec, the relevant mutations for an img element include: "The element's parent is a picture element and a source element that is a previous sibling has its srcset, sizes, media, type, width or height attributes set, changed, or removed." The same applies to source insertion, moving, and removal. Fixes image loading on https://www.apple.com/mac/
