Before this change, we transferred the input element's line-height to
both the editable text *and* the placeholder. This caused some strange
doubling of the effective line-height when the editable text was empty,
pushing down the placeholder.
These were used to provide a layer of abstraction between ResourceLoader
and the networking backend. Now that we only have RequestServer, we can
remove these adapters to make the code a bit easier to follow.
Now that we use libcurl, there's no reason to keep Qt networking around.
Further, it doesn't support all features we need anyways, such as non-
buffered request handling for SSE.
The spec expects `postMessage()` to act as if it is invoked
immediately. Since `postMessage()` isn't actually invoked immediately,
keep tasks with source `PostedMessage` in the task queue, so that these
tasks are processed. Fixes a hang when `WorkerGlobalScope.close()` is
called immediately after `postMessage()`.

Add idl, header and stubs for PerformanceEventTiming interface.
Two missing `PerformanceEntry` types that have come up in issues
are the `first-input` and the `event` entryTypes. Those are both
this.
Also, because both of those are this same interface, the static
methods from the parent class are difficult to implement because
of instance-specific details. Might either need subclasses or to
edit the parent and also everything that inherits from it :/
This test caused some flakiness due to the about:blank load it triggers.
It causes headless-browser to receive a load event for about:blank. If
we have moved onto the next test before that event arrived, that test
would ultimately time out, as its own load will have been dropped while
the about:blank load is still ongoing.
This patch makes us wait for that iframe load event before completing
the test.
We may want to consider never sending subframe load events to the UI
process as well. We really only care about top-level page loads in the
receivers of that event.
We don't create a ChromeProcess in headless-browser, so it is currently
not increasing it's open file limit. This is causing crashes on macOS,
which has a very low default limit.
This uses the setup-python action in the setup action to install python
3.12, and removes the --break-system-packages hack that the system pip
requires.
Before this change viewport was allowed to be scrolled whenever it has a
scrollable overflow, which is not correct when overflow is specified to
be hidden.
Partially reverting a3149c1ce9
Spinning the event loop was causing a crash on:
https://wpt.live/url/percent-encoding.window.html
As it was turning what is meant to be a synchronous operation into an
asynchronous one.
The sequence demonstrated by the reproducing test is as follows:
* A src attribute is changed for the iframe
* process_the_iframe_attributes entered with valid content navigable
* Event loop is spun, allowing the queued iframe removal to execute
* process_the_iframe_attributes continues with null content navigable
* 💥
This reverts commit 556a0936dd.
This was causing a large slow down in WPT, and a crash on macOS during
session shutdown when running WebDriver manually.
Transitions are currently not implemented for pseudo elements which
causes the transition to be applied to the "real"/"parent" element. When
a transition adjusts width/height on a pseudo element this causes the
real elements layout to break.
As a quick fix we just skip doing transitions when they are against
pseudo elements.
We were overly aggressive in clipping SVG roots, which effectively made
them behave as if they always had `overflow: hidden`.
This fixes incorrect clipping of the logo on https://basecamp.com/
Which fixes the following WPT test from failing due to issues stemming
from all of the windows which have been opened.

This will give us 1205 new subtests passing in WPT.
We currently create a single WebView and run all 1400+ LibWeb tests in
serial over that WebView. Instead, let's create as many WebViews as
there are processes on the system, and run LibWeb tests concurrently
over those views.
To do this performantly requires that we never block the main thread of
the headless-browser process once the tests are running. Doing so will
effectively pause execution of all other tests. So test execution is now
Promise-based.
On my machine (with a hardware concurrency of 32), this reduces the run
time of LibWeb tests from 31.382s to 3.640s. CPU utilization increases
from 5% to 67%.
Instead, just log the view's current URL when the WebView crashes. It
won't make any sense to track the executing test this way once there are
many tests running concurrently.
We currently run all tests in a single WebView instance. That instance
owns the process-wide RequestClient / ImageDecoderClient, so if we were
to create a second instance, we'd run into trouble.
This migrates ownership of these services to the Application class, and
makes the Application own the WebView. In the future, this will let the
Application own a list of views.
We currently pass around the individual fields of the Application class
to a bunch of free functions. This makes adding a new field, and passing
it all the way to e.g. run_dump_test pretty annoying, as we have to go
through about 5 function calls.
This will get much worse in an upcoming patch to run LibWeb tests
concurrently. There, we will have to further pass these flags around as
async lambda value captures.
To make this nicer, just access the flags from Application::the(), which
is how the "real" UIs access their application objects as well.
If, by the time we need to schedule rendering of the next frame, the
previous one is still not processed, we could skip it instead of growing
task queue.
Should help with https://github.com/LadybirdBrowser/ladybird/issues/1647
When the flex container is sized under a min-content constraint in the
main axis, any flex items with a percentage main size should collapse
to zero width, not take up their own intrinsic min-content size.
This is not in the spec, but matches how other browsers behave.
Fixes an issue where the cartoons on https://basecamp.com/ were way
too large. :^)
Static position of a box is defined by formatting context type it
belongs to, so let's define this algorithm separately for each FC
instead of assuming FormattingContext::calculate_static_position_rect()
understands how to handle all of them.
Also with this change calculate_static_position_rect() is no longer
virtual function.
At least on my mac, clock_gettime only provides millisecond resolution.
So if many WebContent processes are opened at once, it is not unlikely
that they will all create their backing stores within the same ms. When
that happens, all but the first will fail (and crash).
To prevent this, generate the shared memory file name based on the PID
and a static counter.
We are currently trying to access the current parent and top-level
browsing contexts from the current BC itself. However, if the current BC
is closed, its association to the parent and top-level BCs is lost, and
we are no longer able to handle WebDriver endpoints involving those BCs.
Instead, let's store the parent and top-level BCs separately, and update
them in accordance with the spec.
