Along with putting functions in the URL namespace into a DOMURL
namespace.
This is done as LibWeb is in an awkward situation where it needs
two URL classes. AK::URL is the general purpose URL class which
is all that is needed in 95% of cases. URL in the Web namespace
is needed predominantly for interfacing with the javascript
interfaces.
Because of two URLs in the same namespace, AK::URL has had to be
used throughout LibWeb. If we move AK::URL into a URL namespace,
this becomes more painful - where ::URL::URL is required to
specify the constructor (and something like
::URL::create_with_url_or_path in other places).
To fix this problem - rename the class in LibWeb implementing the
URL IDL interface to DOMURL, along with moving the other Web URL
related classes into this DOMURL folder.
One could argue that this name also makes the situation a little
more clear in LibWeb for why these two URL classes need be used
in the first place.
Resolves a performance regression from
8ba18dfd40, where moving paint scheduling
to `EventLoop::process()` led to unnecessary repaints.
This update introduces a flag to trigger repaints only when necessary,
addressing the issue where repaints previously occurred with each event
loop process, irrespective of actual changes.
With this commit, we are finally running animations off of the web
animations spec! A lot of the work StyleComputer is doing is now done
elsewhere. For example, fill-forward animations are handled by
Animation::is_relevant() returning true in the after phase, meaning the
"active_state_if_fill_forward" map is no longer needed.
This removes the two boolean hack in favor of using the existing
mechanism to remove queued tasks. It also exposes the element
invalidation behavior for call sites that don't necessarily want to
update the finished state, but still need to invalidate the associated
target.
We only need to know that the Global Object of the environment is an
event target in order to dispatch an event on it. This resolves a FIXME
where we assumed that the only type of Global in LibWeb is HTML::Window.
We have a 5 second timeout between a user-activated event occurring and
an activation-gated API being invoked in order for that API to succeed.
This is quite fine in normal circumstances, but the machines used in CI
often exceed that limit (we see upwards of 10 seconds passing between
generating the user-activated event and the API call running).
So instead of generating a user-activated event, add a hook to allow
tests to bypass the very next activation check.
If a call to `document.write` inserts an incomplete HTML tag, e.g.:
document.write("<p");
we would previously continue parsing the document until we reached a
closing angle bracket. However, the spec states we should stop once we
reach the new insertion point.
Extends event loop processing steps to include gathering and
broadcasting resize observations.
Moves layout updates from Navigable::paint() to event loop processing
steps. This ensures resize observation processing occurs between layout
updates and painting.
In this change, updating layout and painting are moved to the EventLoop
processing steps. This modification allows the addition of resize
observation dispatching that needs to happen in event loop processing
steps and must occur in the following order relative to layout and
painting:
1. Update layout.
2. Gather and broadcast resize observations.
3. Paint.
When an <input type=image> button is clicked, we now send the (x,y)
coordinates of the click event (relative to the image) along with the
form submission data.
Regarding the text test, we can currently only test this feature with
dialogs. The headless-browser test infrastructure cannot yet handle the
resulting navigation that would occur if we were to test with normal
form submission.
HTMLFormElement::elements is not the correct filter for submittable
elements. It includes non-submittable elements (HTMLObjectElement) and
also excludes submittable elements (HTMLInputElements in the "image"
type state, "for historical reasons").
This implements enough to represent <input type=image> with its loaded
source image (or fallback to its alt text, if applicable). This does not
implement acquring coordinates from user-activated click events on the
image.
They currently assume the DOM node is an HTMLImageElement with respect
to handling the alt attribute. The HTMLInputElement will require the
same behavior.
Separating the recorder list from the painter will allow us to save it
for later execution without carrying along the painter's state. This
will be useful once we have a separate thread for executing painting
commands, to which we will have to transfer commands from the main
thread.

The setter was missing an implementation for the default and default/on
value attribute modes. This patch adds a method to get the current value
attribute mode, and implements the value setter and getter based on that
mode according to the spec.
There's a chance that we try to choose a navigable before a previously
destroyed navigable is fully destroyed and GC'd. Investigating why this
can happen is a separate endeavor, let's just not crash for now.
This allows for:
* Transformed text (e.g. rotated text)
* Stroked text
* Filling/stroking text with PaintStyles (e.g. gradients)
* Squashed/condensed text (via maxWidth parameter)
Fixes part of #22817
Previously, 'now' was set to the time `requestAnimationFrame()` was
called, and the EventLoop's 'now' was ignored. This was a little odd and
meant the time was always in the past.
In this commit we have optimized the handling of scroll offsets and
clip rectangles to improve performance. Previously, the process
involved multiple full traversals of the paintable tree before each
repaint, which was highly inefficient, especially on pages with a
large number of paintables. The steps were:
1. Traverse the paintable tree to identify all boxes with scrollable or
clipped overflow.
2. Gather the accumulated scroll offset or clip rectangle for each box.
3. Perform another traversal to apply the corresponding scroll offset
and clip rectangle to each paintable.
To address this, we've adopted a new strategy that separates the
assignment of the scroll/clip frame from the refresh of accumulated
scroll offsets and clip rectangles, thus reducing the workload:
1. Post-relayout: Identify all boxes with overflow and link each
paintable to the state of its containing scroll/clip frame.
2. Pre-repaint: Update the clip rectangle and scroll offset only in the
previously identified boxes.
This adjustment ensures that the costly tree traversals are only
necessary after a relayout, substantially decreasing the amount of work
required before each repaint.
When WebDriver asks to destroy a window, we can hit this case with no
active browsing context. This seems odd, but perhaps is a spec issue as
well. Just log to dbgln for now.
This aligns it better with the current state of the spec.
There's still some functions and data members that need moved into
Navigable or TraversableNavigable, but we can leave those for the next
cleanup PR.
