Shannon Booth	f48b760011	LibWeb/CSS: Avoid URL validity check parsing CSS URLs	2025-04-19 07:18:43 -04:00
Shannon Booth	733dfdaa05	LibWeb: Avoid URL validity check for 'Resource' ... Which was previously signally an invalid Resource by a default constructed invalid URL. Instead, switch this over to an Optional URL.	2025-04-19 07:18:43 -04:00
Glenn Skrzypczak	9c758e5f65	LibWeb/HTML: Correctly parse milliseconds in time inputs ... This commit brings the way we parse time inputs closer to the spec by no longer ignoring milliseconds in time strings.	2025-04-19 07:09:36 -04:00
Glenn Skrzypczak	d37d0e4b59	LibWeb: Prevent crash when encoding into detached buffer ... This handles the case where data is encoded into a detached buffer.	2025-04-19 07:08:12 -04:00
Andreas Kling	5df3838a80	LibWeb: Evaluate style sheet media rules immediately on insertion ... Before this change, we were waiting for Document to lazily evaluate sheet media and media rules. This often meant that we'd get two full-document style invalidations: one from adding a new style sheet, and one from the media queries changing state. By evaluating the rules eagerly on insertion, we coalesce the two invalidations into one. This reduces the number of full-document invalidations on Speedometer 3 from 51 to 34.	2025-04-19 01:14:02 +02:00
Andreas Kling	28d564197c	LibWeb: Compute containing block boxes once at start of layout ... We now cache the containing block (box) once at the start of layout, which allows Layout::Node::containing_block() to return instantly instead of doing tree traversal. Removes a 0.7% profile item on Speedometer 3.	2025-04-19 01:14:02 +02:00
Andreas Kling	bbef0e8375	LibWeb: Avoid dynamic_cast in DOM::Document::is_decoded_svg()	2025-04-18 14:45:56 +02:00
Andreas Kling	ce263eaf78	LibWeb: Avoid dynamic_cast in relevant_agent() ... There's only ever one kind of JS::VM::CustomData in play anyway.	2025-04-18 14:45:56 +02:00
Andreas Kling	57809b1100	LibWeb: Skip dynamic_cast in CSSRGB after we already did a type check	2025-04-18 14:45:56 +02:00
Andreas Kling	d8188c9f14	LibJS+LibWeb: Add JS::Object::fast_is<T> helpers for some LibWeb types ... These are slightly unfortunate as we're crossing the library boundary, but there's precedent with Object::is_dom_node(), and these are just knocking down a few more items that were showing up in profiles.	2025-04-18 14:45:56 +02:00
Andreas Kling	207afb0d3b	LibWeb: Avoid double dynamic_cast in parent_element_for_event_dispatch()	2025-04-18 14:45:56 +02:00

Andreas Kling	aecb144df0	LibWeb: Add more fast_is<T> helpers for DOM::Node subclasses	2025-04-18 14:45:56 +02:00
Andreas Kling	0e490e3352	LibWeb: Add fast_is<T> helpers for Navigable & TraversableNavigable	2025-04-18 14:45:56 +02:00
Andreas Kling	f35069d63b	LibJS+LibWeb: Add fast_is<T> helpers for Realm::HostDefined class family	2025-04-18 14:45:56 +02:00
Andreas Kling	a9e415b3c4	LibJS+LibWeb: Add fast_is<T> helpers for HTML::Script class family	2025-04-18 14:45:56 +02:00
Andreas Kling	e7b6b84648	LibWeb: Avoid dynamic_cast in EventTarget initialization ... Let's use a virtual to tell if something uses the WindowOrWorkerGlobalScope mixin instead.	2025-04-18 14:45:56 +02:00
Glenn Skrzypczak	c0cbd439a2	LibWeb/HTML: Dispatch command events ... Command events are now dispatched when buttons are activated. The special commands for popovers and dialogs are also implemented.	2025-04-18 12:09:57 +01:00
Glenn Skrzypczak	cce7d8c0fb	LibWeb/HTML: Implement CommandEvent class ... This implements the `CommandEvent` class.	2025-04-18 12:09:57 +01:00
Glenn Skrzypczak	ffe0b05abd	LibWeb/HTML: Add the commandForElement attribute to the button element ... This commit adds the commandForElement attribute to the button element. Executing commands is not implemented yet.	2025-04-18 12:09:57 +01:00
Glenn Skrzypczak	b2db07f002	LibWeb/HTML: Add the command attribute to the button element ... This commit adds the getter and setter for the command attribute to the button element. Executing commands is not implemented yet.	2025-04-18 12:09:57 +01:00
Timothy Flynn	629cd3c42a	LibWeb: Sort remaining stream AOs (mostly) in spec order ... The remaining AOs can stay where they are. This patch just sorts them in spec order to match the other AO files. Section 8.1 is last, however, as these are all templates and need the declarations of other AOs above.	2025-04-18 06:55:40 -04:00
Timothy Flynn	3e8c6dbaff	LibWeb: Move TransformStream AOs into their own file ... The main streams AO file has gotten very large, and is a bit difficult to navigate. In an effort to improve DX, this migrates TransformStream AOs to their own file.	2025-04-18 06:55:40 -04:00
Timothy Flynn	26c01f0957	LibWeb: Move WritableStream AOs into their own file ... The main streams AO file has gotten very large, and is a bit difficult to navigate. In an effort to improve DX, this migrates WritableStream AOs to their own file.	2025-04-18 06:55:40 -04:00
Timothy Flynn	a9ddd427cb	LibWeb: Move ReadableStream AOs into their own file ... The main streams AO file has gotten very large, and is a bit difficult to navigate. In an effort to improve DX, this migrates ReadableStream AOs to their own file. And the helper classes used for the tee and pipe- to operations are also in their own files.	2025-04-18 06:55:40 -04:00
Timothy Flynn	c35ef36293	LibWeb: Fix typos in ReadableStream AO names	2025-04-18 06:55:40 -04:00
Sam Atkins	141f6cb392	LibWeb/HTML: Use relevant global object's document in History ... Corresponds to dba6e7b6c2 and 4c0401186c The spec algorithms now use "the relevant global object's associated document", so remove the concept of the History object itself having an associated document. The spec has also combined the implementations for forward/back/go so I've matched that too.	2025-04-18 10:49:56 +02:00
Sam Atkins	5b57856eae	LibWeb/HTML: Check associated document is fully active, not the window ... This is a spec change, but we already implemented the correct version. Corresponds to aa39b6b6b0	2025-04-18 10:49:56 +02:00
Sam Atkins	343df5d00f	LibWeb: Update focus-related spec text ... Corresponds to 03ab71775b I've also split the `Document::has_focus()` method for clarity. Actually implementing the "has focus steps" turns out to be quite involved so I've left it for now.	2025-04-18 10:49:56 +02:00
Sam Atkins	609d568776	LibWeb: Remove "locked for focus" concept ... Corresponds to 5ba23f9f6d	2025-04-18 10:49:56 +02:00
Shannon Booth	3e17b1c9ae	LibWeb: Make Node::parent_element return GC::Ptr ... This is useful for people like myself who run with debug mode to more reliably get stacktraces without spinning up a debugger.	2025-04-18 10:49:02 +02:00
Shannon Booth	a14481ee05	LibWeb/HTML: Handle no parent element for Element::list_owner ... Fixes a crash when running Speedometer 3.0 as reduced in the included test case.	2025-04-18 10:48:47 +02:00
Andreas Kling	832b0a0ace	LibWeb: Invalidate style when HTMLDialogElement modal state changes ... This fixes Layout/input/dialog-open-modal.html which began flaking super hard after the preceding commits that reduced style invalidation for focus-related pseudo class selectors.	2025-04-17 19:45:55 +02:00
Andreas Kling	8d51c41a42	LibWeb: Remove no-longer-used StyleInvalidationReasons :^)	2025-04-17 19:45:55 +02:00
Andreas Kling	55ab8ff539	LibWeb: Use optimized invalidation for :active pseudo class	2025-04-17 19:45:55 +02:00
Andreas Kling	6da48c60ca	LibWeb: Use optimized invalidation for target-related pseudo classes	2025-04-17 19:45:55 +02:00
Andreas Kling	414e0cc930	LibWeb: Use optimized invalidation for focus-related pseudo classes	2025-04-17 19:45:55 +02:00
Andreas Kling	e1777f6e79	LibWeb: Make :hover invalidation logic reusable for all pseudo classes ... We achieve this by keeping track of all checked pseudo class selectors in the SelectorEngine code. We also give StyleComputer per-pseudo-class rule caches.	2025-04-17 19:45:55 +02:00
Andreas Kling	ed35f9e7c2	LibWeb: Remove unused MatchingRule::must_be_hovered flag ... This was a vestige from an earlier version of hover selector work avoidance optimizations.	2025-04-17 19:45:55 +02:00
Timothy Flynn	60f667fc5a	LibWeb: Use (de)serialization with transfer AOs for structured cloning ... This is important, for example, to detach transferred array buffers.	2025-04-17 12:13:13 -04:00
Timothy Flynn	5eab109d85	LibWeb: Update structured deserialization to accept its target realm ... This is a formal parameter to this AO in the spec.	2025-04-17 12:13:13 -04:00
Vishal Biswas	eb165554e1	LibWeb: Use double type in ProgressEvent ... loaded and total should be double as per spec https://xhr.spec.whatwg.org/#progressevent	2025-04-17 08:28:47 -04:00
Vishal Biswas	d56f6805d3	LibWeb: Mimic if-condition from spec ... https://xhr.spec.whatwg.org/#dom-xmlhttprequest-abort	2025-04-17 08:28:47 -04:00
Tim Ledbetter	ca200142e9	LibWeb: Don't construct stylesheet when modifying CSSStyleSheet rules ... Previously, `CSSStyleSheet.replace()` and `CSSStyleSheet.replaceSync()` parsed the given CSS text into a temporary stylesheet object, from which a list of rules was extracted. Doing this had the unintended side-effect that a fetch request would be started if the given CSS text referenced any external resources. This fetch request would cause a crash, since the temporary stylesheet object didn't set the constructed flag, or constructor document. We now parse the given CSS text as a list of rules without constructing a temporary stylesheet.	2025-04-16 22:03:12 +01:00
Timothy Flynn	955f6fc9cb	LibWeb: Fulfill TransformStream promises with the correct "reason" ... We need to use the reason provided to the abort algorithm, not the one from the resolved cancel promise (which will be undefined).	2025-04-16 13:15:33 -04:00
Andrew Kaster	ea68944149	LibWeb: Store LibGfx objects in RefPtr to const for draw commands	2025-04-16 10:41:44 -06:00
Andrew Kaster	c36c7ed67b	LibWeb: Launder const in CSS::Selector::absolutized when returning self ... This const method tries to return a RefPtr to non-const self. That's not kosher, but fixing it needs some architecture work.	2025-04-16 10:41:44 -06:00
Andrew Kaster	4b7f4aef10	LibWeb: Pass RefPtr to const to ClippableAndScrollable setters ... We were already storing the ClipFrame and ScrollFrame in RefPtr to const but we were passing them as RefPtr to non-const to the setters.	2025-04-16 10:41:44 -06:00
Andrew Kaster	280ae45210	LibWeb: Pass ImageData as non-const to CanvasImageData mixin methods ... CRC2D needs to manipulate the ImageData object in put_image_data()	2025-04-16 10:41:44 -06:00
Andrew Kaster	be2dd91289	LibGfx+LibWeb: Store Typeface and Font-related types in RefPtr to const	2025-04-16 10:41:44 -06:00
