Before this change, "background-clip: text" was implemented by saving a
Vector<Gfx::Path> of all glyphs needed to paint a mask for the
background. The issue with this approach was that once glyphs were
extracted into vector paths, the glyph rasterization cache could no
longer be utilized.
With this change, all text required for mask painting is saved in a
nested display list and rasterized as a regular text.
This change is a preparation for the upcoming changes where display
list will be nested and the same display could be owned by multiple
display list items.
With this change display list player will be able to recurse into
executing another display list, without having to construct new display
list player. It is going to be useful in the upcoming changes to paint
a mask from a display list owned by a command.
Previously, when creating a HTML element with
`document.createElementNS()` we would convert the given local name to
lowercase before deciding which element type to return. We now no
longer perform this lower case conversion, so if an uppercase local
name is provided, an element of type `HTMLUnknownElement` will be
returned. This aligns our implementation with the specification.
Instead of multiple loops and multiple vectors, parse Wasm expressions
in a simple loop. This gets us from ~450ms to instantiate spidermonkey
to ~280ms.
`swizzle` had the wrong operands, and the vector masking boolean logic
was incorrect in the internal `shuffle_or_0` implementation. `shuffle`
was previously implemented as a dynamic swizzle, when it uses an
immediate operand for lane indices in the spec.
CommandResult was needed by LibGfx display list player that could have
failed to allocate a temporary bitmap for painting a stacking context
with CSS transforms. This is no longer an issue with Skia painter, so
we can delete CommandResult::SkipStackingContext handling path.
This is called by https://athenacrisis.com/ and passed through to
AudioNode.connect, which expects an AudioNode.
Implement this function enough so that we return an AudioNode so that
AudioNode.connect does not throw a TypeError.
This is an AudioNode representing the final audio destination and is
what the user will ultimately hear.
This node is used as one of the connecting nodes in athenacrisis.com
Add a placeholder for the interface without anything backing it for now.
With this change, instead of recording a display list item for each
instance of a repeated background, a new DrawRepeatedImmutableBitmap
type is used. This allows the painter to use optimized repeated image
painting and, when the GPU backend is used, avoid re-uploading the image
texture for each repetition.
Some screenshot tests are affected, but there are no visible
regressions.

The :host family of pseudo class selectors select the shadow host
element when matching against a rule from within the element's shadow
tree.
This is a bit convoluted due to the fact that the document-level
StyleComputer keeps track of *all* style rules, and not just the
document-level ones.
In the future, we should refactor style storage so that shadow roots
have their own style scope, and we can simplify a lot of this.
This fixes an issue where :host(foo) would parse as if "foo" was the
on the right side of a descendant combinator.
Not testable yet, but will be in the next commit.
We don't want to set the intrinsic Console object's client to non-top-
level clients, created for e.g. SVG elements or subframes. We also want
to make sure the Console client is updated if the top-level document has
changed.
Checking that the string parsed for the `font` property is not enough,
the spec also wants to rule out CSS-wide keywords like `inherit`. The
simplest way to do so is to check if it's a ShorthandStyleValue, which
also rules out use of `var()`; this matches other browsers' behaviour.
The newly-added test would previously crash, and now doesn't. :^)
It’s possible but unlikely that a push of generated notes back to the
remote can fail with a message like
> [remote rejected] ... cannot > lock ref 'refs/notes/commits': is at
> f3648f50bb but expected 47686bf473
See https://github.com/LadybirdBrowser/ladybird/actions/runs/10054314539
So this change makes the call to “git push” for notes not return 0 even
if it fails — because it’s not actually a fatal error when it happens,
and not something we need to stop and fix. Instead, it fixes itself.
Specifically: If one CI job for a PR merge/push to master generates
some notes but fails to push them to the origin, the notes don’t get
dropped on the floor and lost.
Instead, the notes-generator tool looks at the entire history; and if it
finds commits that don’t have notes — even if those commits are not part
of the PR push/merge it’s operating on — it generates notes for those.
In other words, if notes for one PR push/job fail for some reason to get
pushed back to the remote, they get regenerated by the next PR push/job.
The typeof operator has a very small set of possible resulting strings,
so let's make it much faster by caching those strings on the VM.
~8x speed-up on this microbenchmark:
for (let i = 0; i < 10_000_000; ++i) {
typeof i;
}
Before this change, removing a style element from inside a shadow tree
would cause it to be unregistered with the document-level list of sheets
instead of the shadow-root-level list.
This would eventually lead to a verification failure if someone tried to
update the text contents of that style element, since it was still in
the shadow-root-level list, but now with a null owner element.

The default limit (at least on Linux) causes us to run out of file
descriptors at around 15 tabs. Increase this limit to 8k. This is a
rather arbitrary number, but matches the limit set by Chrome.
