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.
https://null.com/games/chainstaff works a lof faster with this change.
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.
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. :^)
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.

Previously, if a document had any element with a name attribute that
was set to the empty string, then `document.getElementsByName("")` and
`element.getElementsByName("")` would return a collection including
those elements.
Previously, if a document had an element whose id was the empty string,
then `document.getElementById("")` and `element.getElementById("")`
would return that element.
Previously, `SVGSVGBox` would have a natural aspect ratio of 0 if it
had a viewbox with zero width. This led to a division by zero, causing
a crash.
Found by Domato.
Previously calling `PaintableBox::set_scroll_offset()` with a
PaintableBox whose content size was larger than its scrollble overflow
rect would cause a crash.
Found by Domato.
We had a const and non-const version of this function, with slightly
different behavior (oops!)
This patch consolidates the implementations and keeps only the correct
behavior in there.
Fixes an issue where comments were not collapsible on Hacker News.
Skia painter is visibly faster than LibGfx painter and has more complete
CSS transforms support. With this change:
- On Linux, it will try to use Vulkan-backend with fallback to
CPU-backend
- On macOS it will try to use Metal-backend with fallback to
CPU-backend
- headless-browser always runs with CPU-backend in layout mode
These test work with LibGfx painter but won't longer work after
switching to Skia, because it produces slightly different antialiasing,
rounding in color blending, etc.
This is the expected behavior per the HTML spec. Fixes an issue where
styling these elements wouldn't have the expected effect unless you also
set the display property.
Instead of allowing arbitrarily large values (which could eventually
overflow an i32), let's just cap them at the same limit as Firefox does.
Found by Domato.
This change will make it easier to disable screenshot comparison tests
on a specific platform or have per-platform expectations.
Additionally, it's nice to be able to tell if a ref-test uses a
screenshot as an expectation by looking at the test path.
Areas are disassembled into boundary lines on `build_grid_areas()` step,
so we can always use them to find grid item's position during placement.
This way we support both ways to define area: `grid-template-areas` and
implicitly using `-start` and `-end` boundary line names.
- Change min track sizing function to be "auto" when flex size is
specified.
- Never check if min track sizing funciton is flexible, because only
max is allowed to be flexible.
- Address FIXME in automatic_minimum_size to avoid regressions after
making two fixes mentioned above.
The change causes Tests/LibWeb/WPT/run.sh to run an arbitrary subset of
tests you give it as arguments. If you don’t specify any arguments, it
has the same behavior as it does without this patch: It just runs an
explicit subset of test names hardcoded into the script.
Otherwise without this change, Tests/LibWeb/WPT/run.sh doesn’t have the
ability to run any tests other than the explicit subset of test names
hardcoded into the script
When traversing the layout tree to find an appropriate box child to
derive the baseline from. Only the child's margin and offset was being
applied. Now we sum each offset on the recursive call.
The spec says to just call the XML serialization algorithm, but it
returns the "outer serialization", and we need the "inner" one. Let's
just concatenate serializations of children; then the result produced is
similar to one from Blink or Gecko.
This method puts the given node and all of its sub-tree into a
normalized form. A normalized sub-tree has no empty text nodes and no
adjacent text nodes.
Previously the input element was displayed with value 0, when no value
was set in the HTML. Now it uses `value_sanitization_algorithm()`, which
will calculate the default value.
In `value_sanitization_algorithm()` there was a logical mistake/typo.
The comment from the spec says "unless the maximum is less than the
minimum".
The added layout test would fail without the code changes.
Fixes#520
When the min option is given the read will only be fulfilled when there
are min or more elements available in the readable byte stream.
When the min option is not given the default value for min is 1.
The first time Document learns its viewport size, we now suppress firing
of the resize event.
This fixes an issue on multiple websites that were not expecting resize
events to fire so early in the loading process.
Previously, setting CSS `line-height: 0` on an `input` element would
result in no text being displayed.
Other browsers handle this by setting the minimum height to the
"normal" value for single line inputs.
From https://html.spec.whatwg.org/multipage/scripting.html#script-processing-model:
When a script element el that is not parser-inserted experiences one
of the events listed in the following list, the user agent must
immediately prepare the script element el:
- [...]
- The script element is connected and has a src attribute set where
previously the element had no such attribute.
Previously, when `WindowOrWorkerGlobalScope.reportError()` was called
the `filename` property of the dispatched error event was blank. It is
now populated with the full path of the active script.
Like 1132c858e9, out-of-flow elements such
as float elements would get inserted into block level `::before` and
`::after` pseudo-element nodes when they should instead be inserted as a
sibling to the pseudo element. This change fixes that.
This fixes a few layout issues on the swedish tax agency website
(skatteverket.se). :^)
This makes it so that `rebaseline-libweb-test` can be run on *nix or
MacOS as the path to `headless-browser` on MacOS is
`./bin/Ladybird.app/Contents/MacOS/headless-browser` while it is
`./bin/headless-browser` on *nix.
Following the rules in the algorithm from
https://webidl.spec.whatwg.org/#js-platform-objects, "To Internally
create a new object implementing the interface interface", this change
incorporates the steps to load a prototype from new.target, and write
it to the created instance returned from constructor_impl(). This
mirrors the code for generate_html_constructor(), which incorporates
additional steps needed by Custom Elements.
Bug #334
This is a non-standard API that other browsers implement, which
highlights matching text in the current window.
This is just a thin wrapper around our find in page functionality, the
main motivation for adding this API is that it allows us to write tests
for our find in page implementation.
If a flex item has a preferred aspect ratio and the flex basis is not
definite, we were falling back to using stretch-fit for the main size,
since that appeared to match other browsers.
However, we missed the case where we actually have a definite cross size
through which the preferred aspect ratio can be naturally resolved.
To get away from the ancient (and buggy) text layout code in
Gfx::Painter, we want to remove all the uses of Painter::draw_text().
As a first step towards this, we implement the draw_text() display list
command in terms of the draw_text_run() command by performing the very
simple necessary layout in draw_text() beforehand.
The values aren't that complex, so it doesn't make much sense to have a
dedicated generator for them. Parsing them manually also allows us to
have much more control over the produced values, so as a result of this
change, EasingStyleValue becomes much more ergonomic.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
The DocumentTimeline constructor used the current millisecond time to
initialize its currentTime, but that means that a newly created timeline
would always have a different time value than other timelines that have
been through the update_animations_and_send_events function.
`Painting::paint_all_borders()` only uses `.draw_line()` for simple
borders and `.fill_path()` for more complex cases. These are both
already supported by the `RecordingPainter` so removing this command
simplifies the painting API.
Two test changes:
css-background-clip-text: Borders are now drawn via the AA painter
(which makes them closer to how they appear in other browsers).
corner-clip-inside-scrollable: Borders removed (does not change test)
due to imperceptible sub-pixel changes.
Previously, we always cast to a HTMLInputElement when getting the value
of an auto directionality form associated element. This caused
undefined behavior when determining the directionality of an element
that wasn't a HTMLInputElement.
Previously, we assumed that all label control paintables were of type
`LabelablePaintable`. This caused a crash when clicking on a label with
a text input control.
This initializes 'arrayBuffer' to an UInt8Array so that we can
manipulate the contents of 'arrayBuffer'. The test verifies that the
internal buffer is an ArrayBuffer.
Also:
* Correct comparison in test so that we compare arrayBuffer to
arrayClone, not to itself.
* Remove FIXME, this outputs [object ArrayBuffer] in Firefox and Chrome
too.
All painting commands except SetClipRect are shifted by scroll offset
before command list execution. This change removes scroll offset
translation for sample/blit corner commands in
`PaintableWithLines::paint` so it is only applied once in
`CommandList::apply_scroll_offsets()`.
