stelar7	0890b10d11	LibWeb/IDB: Improve error messages related to transaction state	2025-05-06 11:16:01 +02:00
Bastiaan van der Plaat	58b735010b	LibWeb: Add -webkit-box-* legacy CSS property aliases	2025-05-05 23:36:31 +02:00
Andreas Kling	183c847c80	LibJS: Cache PutById to setters in the prototype chain ... This is *extremely* common on the web, but barely shows up at all in JavaScript benchmarks. A typical example is setting Element.innerHTML on a HTMLDivElement. HTMLDivElement doesn't have innerHTML, so it has to travel up the prototype chain until it finds it. Before this change, we didn't cache this at all, so we had to travel the prototype chain every time a setter like this was used. We now use the same mechanism we already had for GetBydId and cache PutById setter accesses in the prototype chain as well. 1.74x speedup on MicroBench/setter-in-prototype-chain.js	2025-05-05 15:21:43 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Psychpsyo	7c36a82129	LibWeb: Improve parsing for the CSS contain property ... This makes us actually respect the grammar and nets us a couple extra WPT passes in the parsing section.	2025-05-04 22:24:26 +01:00
Timothy Flynn	1c075d6039	LibWeb: Remove Web::Infra ASCII case conversion methods ... We have more optimized versions of these methods in AK.	2025-05-04 15:59:17 +02:00
Sam Atkins	de6df6f403	LibWeb/CSS: Parse and use CSS URL request modifiers	2025-05-03 23:22:40 +01:00
Sam Atkins	a1fb34d7f2	LibWeb/CSS: Alphabetize Enums.json	2025-05-03 23:22:40 +01:00
Shannon Booth	e476d21ed0	LibJS: Add and use PrimitiveString::length_in_utf16_code_units ... I was investigating an optimization in this area, and while it didn't seem to have a noticable improvement, it still seems useful to apply this change.	2025-05-03 16:18:47 +02:00
Sam Atkins	560317b3d0	LibWeb/CSS: Update spec comment in calc() simplification algorithm ... This was corrected in 8bcf3ada9e	2025-05-03 14:54:33 +01:00
Sam Atkins	1cb1526178	LibWeb/CSS: Remove document-URL hack from create_a_style_sheet() ... We no longer need this, because we don't complete URLs during parsing, and the location is set elsewhere when needed.	2025-05-03 12:01:43 +01:00
Sam Atkins	bc1d323ba0	LibWeb/CSS: Remove URL parameter to the CSS Parser ... We no longer complete any URLs during parsing.	2025-05-03 12:01:43 +01:00
Sam Atkins	9e2e796f2d	LibWeb/CSS: Use CSS::URL for font-fetching ... ParsedFontFace and FontLoader now both keep track of which CSSStyleSheet (if any) was the source of the font-face, so the URLs can be completed correctly.	2025-05-03 12:01:43 +01:00
Sam Atkins	14fb567a0f	LibWeb/CSS: Stop overwriting style sheet location after construction	2025-05-03 12:01:43 +01:00
Sam Atkins	981ede900a	LibWeb/DOM: Create style element style sheets with document's base URL ... This is the simplest fix I could find that resolves a buggy interaction between this and the CSS fetch algorithms, which also doesn't regress anything. (As far as I can tell.)	2025-05-03 12:01:43 +01:00
Sam Atkins	7a4854732a	LibWeb/CSS: Make CSS::URL formattable	2025-05-03 12:01:43 +01:00
Sam Atkins	efad6e96aa	LibWeb/CSS: Set CSSFontFaceDescriptors' parent rule	2025-05-03 12:01:43 +01:00
Sam Atkins	ffc01626f7	LibWeb/CSS: Load fonts using fetch ... Convert FontLoader to use fetch_a_style_resource(). ResourceLoader used to keep its downloaded data around for us, but fetch doesn't, so we use Gfx::Typeface::try_load_from_temporary_memory() so that the font has a permanent copy of that data.	2025-05-03 12:01:43 +01:00
Sam Atkins	f76f8dcce1	LibWeb/CSS: Return the FetchController from fetch_a_style_resource()	2025-05-03 12:01:43 +01:00
Sam Atkins	6b762331df	LibGfx: Rename WOFF[2]::try_load_from_externally_owned_memory() ... Typeface::try_load_from_externally_owned_memory() relies on that external owner keeping the memory around. However, neither WOFF nor WOFF2 do so - they both create separate ByteBuffers to hold the TTF data. So, rename them to make it clearer that they don't have any requirements on the byte owner.	2025-05-03 12:01:43 +01:00
Tim Ledbetter	23009779e1	LibWeb: Interpolate font-style values correctly ... These are interpolated by computed value, except a value of `normal` is treated as `oblique 0deg`.	2025-05-03 12:05:22 +02:00
Tim Ledbetter	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	2025-05-03 12:05:22 +02:00
Timothy Flynn	ea77092100	LibWeb: Begin implementing SharedWorker ... Shared workers are essentially just workers that may be accessed from scripts within the same origin. There are plenty of FIXMEs here (mostly building on existing worker FIXMEs that are already in place), but this lets us run the shared worker variants of WPT tests.	2025-05-02 17:48:02 -04:00
Timothy Flynn	469d5ccc4b	LibWeb: Add FIXME about Worker's constructor's scriptURL parameter ... TrustedScriptURL is its own interface that we haven't implemented yet.	2025-05-02 17:48:02 -04:00
Timothy Flynn	56f047119c	LibWeb: Alphabetically sort LibWeb sources ... I sorted this list when added shared worker sources, and this is the fallout.	2025-05-02 17:48:02 -04:00
Timothy Flynn	912009f6b3	LibWeb: Implement navigator.clipboard.read	2025-05-02 17:46:16 -04:00
Timothy Flynn	a4e9a27343	LibWeb: Implement navigator.clipboard.write	2025-05-02 17:46:16 -04:00
Timothy Flynn	a1985e57e7	LibWeb: Implement navigator.clipboard.readText	2025-05-02 17:46:16 -04:00
Timothy Flynn	61c0f67c8c	LibWeb+LibWebVew+WebContent+UI: Add IPC to retrieve the system clipboard ... We currently have a single IPC to set clipboard data. We will also need an IPC to retrieve that data from the UI. This defines system clipboard data in LibWeb to handle this transfer, and adds the IPC to provide it.	2025-05-02 17:46:16 -04:00
Timothy Flynn	5fb5066e89	LibWeb: Initialize plain boolean in ClipboardItem::Representation	2025-05-02 17:46:16 -04:00
Timothy Flynn	4a9ed67e9d	LibWeb: Do not store clipboard items in an unprotected vector	2025-05-02 17:46:16 -04:00
Bastiaan van der Plaat	832bb978f5	LibWeb: Reject CSS values with unprocessed tokens / extra semicolons	2025-05-02 11:10:02 +01:00
Bastiaan van der Plaat	b99f4872d1	LibWeb: Allow transform calculated length properties	2025-05-02 11:10:02 +01:00
Tim Ledbetter	542c3cbe51	LibWeb: Implement the transition-behavior CSS property ... This specifies whether transitions should be started for transitions whose animation behavior is discrete.	2025-05-02 11:07:19 +01:00
Jelle Raaijmakers	e57e38dafc	LibWeb: Use as_if<T> in TreeNode methods ... Using `as<T>` calls into `as_if<T>`, so let's just immediately use that for the "node of type" iterators. No functional changes.	2025-05-02 11:02:20 +02:00
Jelle Raaijmakers	295b78f7d3	LibWeb: Do not rely on the layout tree for collapsed line breaks ... The editing command that relies the most on this, `insertLinebreak`, did not perform a layout update after inserting a `<br>` which caused this algorithm to always return false. But instead of actually building the layout tree needlessly, we can check the DOM tree instead.	2025-05-01 15:44:26 +03:00
Psychpsyo	82387e2127	LibWeb: Avoid changing button border color on disable/hover	2025-04-30 20:13:14 +01:00
Tim Ledbetter	c72d5943e6	LibWeb: Support interpolating translate values	2025-04-30 19:36:56 +02:00
Tim Ledbetter	27baaa13e9	LibWeb: Support parsing and serializing 3D translate values	2025-04-30 19:36:56 +02:00
Tim Ledbetter	d804f1311c	LibWeb: Don't serialize scale z value if it is 1	2025-04-30 19:36:56 +02:00
Sam Atkins	094c2bbc89	LibWeb/SVG: Remove remaining user of of old try_resolve_url_to()	2025-04-30 17:38:38 +01:00
Sam Atkins	326933cd93	LibWeb/CSS: Use CSS::URL for <url> and <paint> types	2025-04-30 17:38:38 +01:00
Sam Atkins	d301510ab2	Everywhere: Correct "FIMXE" typo	2025-04-30 17:38:38 +01:00
Andrew Kaster	edfaa76c90	LibWeb: Exit the current process when event loop quits during spin_until ... This is a LibWeb special. We keep running into cases where we end up with one or more Platform or event loop spin_until() calls on the stack after the event loop has been cancelled and the WebContent process has been asked to exit. To prevent too much nonsense from exiting processes early from affecting our other, more well-behaved processes, put this special logic in the critical path of such Web-specific event loop spins.	2025-04-30 11:12:23 -04:00
Andrew Kaster	b4f34ee860	LibWeb: Remove unnecessary VERIFY from EventLoopPlugin's deferred_invoke	2025-04-30 11:12:23 -04:00
Timothy Flynn	0cd5e99066	LibWeb: Use the correct target realm to tee a stream ... We currently store Web::Fetch::Infrastructure::Response objects in the HTTP cache. They are associated with their original realm, but when we use a cached response, we clone it into the target realm. For example, two <iframe> objects loading the same HTML will be in different realms. When we clone the response, we must use the target realm throughout the entire cloning process. We neglected to do this for the cloned response body stream, which is cloned via teeing. The result was the the stream for the "cloned" response was created in the original realm, causing issues down the line when reading from that stream tried to handle read promises on behalf of the original realm. There are protections in place to prevent this from happening, and the cached response read would never complete.	2025-04-30 09:30:15 -04:00
Timothy Flynn	6cc5ac8f82	LibWeb: Remove unused VM from ReadLoopReadRequest	2025-04-30 09:30:15 -04:00
Gingeh	004d1305c8	LibWeb: Don't accidentally create a layout node for display: none	2025-04-30 11:26:18 +01:00
Andrew Kaster	e5465ff8e5	LibWeb: Crash less when the main thread exits while trying to render ... Attach a 'job' to the main thread event loop, trusting that the event loop implementation will cancel it when asked to quit. This is something that our Unix implementation does, but isn't strictly part of the contract of EventLoopImplementation.	2025-04-29 09:51:22 -06:00
stelar7	81d7f27c73	LibWeb/IDB: Fix record checking using the wrong key comparison	2025-04-29 17:06:17 +02:00
