This reverts commit c14173f651. We
should only annotate the minimum number of symbols that external
consumers actually use, so I am starting from scratch to do that
RegExp was the only caller relying on being able to provide an offset
larger than the string length. So let's do a pre-check in RegExp and
then enforce that the offsets we receive in Utf16View are valid.
Partial interfaces have the same name as the interface they extend, and
can appear in any order. In practice, we import the partial interfaces
into the main interface's IDL.
`curl_easy_recv` must be called in a loop until it returns EAGAIN,
because it may cache data, but only activate the read notifier once.
Additionally, the data received can contain multiple WebSocket frames
and only activate the notifier once, so we have to keep reading frames
until there isn't enough data.
We also have to do this immediately after connecting a WebSocket,
since the server may immediately send data when the WebSocket opens
and before we create the read notifier.
This makes Discord login faster and more reliable, and makes Discord
activities start loading.
Before this change, calc() would resolve to different types depending on
the nearest containing value context. This meant that rgb(calc(), ...)
by itself worked correctly due to fallbacks, but rgb(calc(), ...) inside
e.g a linear-gradient would create a calc() value that resolves to a
length, which subsequently got rejected by the color value parser.
Fixing this makes various little gradients show up on Discord.
There apparently is a bit of a disconnect between the spec asking us to
construct the pattern using code points and LibRegex not being able to
swallow those. Whenever we had multi-byte code points in the pattern and
tried to match that in unicode mode, we would fail.
Change the parser to encode all non-ASCII code units. Fixes 2 test262
cases in `language/literals/regexp`.
We were calling into `view.length()`, which potentially returned the
code _point_ length for Utf16Views. Make sure we use the code unit
length instead, since we're only indexing into code units.
At some point `hue-rotate` was changed to use `AngleOrCalculated`
rather than `Angle`, but `Angle` was still being used in a `visit`,
which otherwise defaulted to zero. This caused all `hue-rotate` angles
to serialize to zero.
`operator[]` -> `code_point_at`
`code_unit_at` -> `unicode_aware_code_point_at`
`unicode_aware_code_point_at` returns either a code point or a code unit
depending on the Unicode flag.
Fixes bug when `build_matching_rule_set()` mistakenly included all
unlayered rules twice. This was caused by mistakenly including all
unlayered rules into `""` named "service" layer, because we couldn't
tell if FlyString = `""` means no layer or layer named `""`.
Previously, an SVG with width of zero would have am intrinsic aspect
ratio of zero. With this change, if an SVG has a width or height of
zero, the intrinsic aspect ratio is determined by the SVG's viewbox.
...for `text-justify: inter-character`.
We previously had this mapped in Enums.json, but the behaviour is
different: `a=b` in Enums.json keeps `a` around but makes it behave the
same as `b`. A legacy name alias is instead expected to replace `a`
with `b`, so we have to do that separately.
We don't yet have a system for "legacy value aliases", but until we have
a lot of them we can handle them manually.
We also have to do this in two places because
parse_css_value_for_property() doesn't call any property-specific
parsing code.
Before this change we were running the CSS cascade machinery twice per
element:
- First, to compute the "logical alias mapping context" based on
writing-mode and pals.
- Then, to compute all properties.
This patch factors out the heaviest work from the cascade machinery
to a separate step that can be run only once. This step will:
- Collect all the matching rules for the element
- Resolve custom properties for the element
We still perform the per-element cascade twice, but now this is hogging
less than 1% of CPU time when typing on Discord (compared to 9% before.)
The specification [1] indicates that the tentative used width and height
should be computed first, and if they exceed the `max-width` or
`max-height`, the rules should be applied again using the computed
values of `max-width` and `max-height`.
The only required change to follow the spec is to remove the early
`return` statements, in both `compute_width_for_replaced_element`
and `compute_height_for_replaced_element`.
Fixes#5100.

To make {,de}serialization of ImageBitmap work we also had to add
support for creating an ImageBitmap from a HTMLCanvasElement in
WindowOrWorkerGlobalScopeMixin::create_image_bitmap_impl().
This refactors out the reading part of Gfx::Bitmap from
HtmlCanvasElement::surface(). We can then reuse this from
WindowOrWorkerGlobalScopeMixin::create_image_bitmap_impl() when we
create an ImageBitmap from a HtmlCanvasElement.
1. Fix typos in some macro invocations of these error types. We now use
a single xmacro to instantiate error definitions to prevent such
errors in the future.
2. Use the "WebAssembly." prefix as needed.
3. Allocate the error constructors and prototypes with `realm.create`
rather than `heap.allocate`. The latter does not invoke `initialize`
methods. This exposed the next issue:
4. Use the correct intrinsic prototype in the error constructor. We were
using the base native error prototype. We unfortunately cannot invoke
OrdinaryCreateFromConstructor from LibJS directly with the correct
prototype, so an implementation was added here.
5. Use intrinsic accessors to create the constructors. I don't think
this one was actually a fix, but it makes the setup look more like
other built-ins.
This fixes an issue where only the last KeyframeEffect applied to an
element would actually have an effect on the computed properties.
It was particularly noticeable when animating a shorthand property like
border-width, since only one of the border edges would have its width
actually animate.
By deferring the invalidation until all animations have been processed,
we also reduce the amount of work that gets done on pages with many
animations/transitions per element. Discord is very fond of this for
example.
Using the new hooks in the XML Parser's listener interface, we now
append DOM nodes for CDATASections and ProcessingInstructions
to the document as they are encountered. This commit also fixes where
comment nodes are appended, ensuring they are added to the current node
instead of the document root.
This allows listeners to be notified when a CDATASection or
ProcessingInstruction is encountered during parsing. The non-listener
path still has the incorrect behavior of silently treating CDATASection
as Text nodes, but this allows listeners to handle them correctly.
