This is an attempt to bring the size of Parser.cpp down. No code
changes, just moves and some explicit template instantiations now that
we're using them from a different file.
This is a mixin in the IDL, so let's treat it as a mixin in our code and
let both SVGElement and MathMLElement reuse the implementations that we
wrote for HTMLElement.
This input event handling change is intended to address the following
design issues:
- Having `DOM::Position` is unnecessary complexity when `Selection`
exists because caret position could be described by the selection
object with a collapsed state. Before this change, we had to
synchronize those whenever one of them was modified, and there were
already bugs caused by that, i.e., caret position was not changed when
selection offset was modified from the JS side.
- Selection API exposes selection offset within `<textarea>` and
`<input>`, which is not supposed to happen. These objects should
manage their selection state by themselves and have selection offset
even when they are not displayed.
- `EventHandler` looks only at `DOM::Text` owned by `DOM::Position`
while doing text manipulations. It works fine for `<input>` and
`<textarea>`, but `contenteditable` needs to consider all text
descendant text nodes; i.e., if the cursor is moved outside of
`DOM::Text`, we need to look for an adjacent text node to move the
cursor there.
With this change, `EventHandler` no longer does direct manipulations on
caret position or text content, but instead delegates them to the active
`InputEventsTarget`, which could be either
`FormAssociatedTextControlElement` (for `<input>` and `<textarea>`) or
`EditingHostManager` (for `contenteditable`). The `Selection` object is
used to manage both selection and caret position for `contenteditable`,
and text control elements manage their own selection state that is not
exposed by Selection API.
This change improves text editing on Discord, as now we don't have to
refocus the `contenteditable` element after character input. The problem
was that selection manipulations from the JS side were not propagated
to `DOM::Position`.
I expect this change to make future correctness improvements for
`contenteditable` (and `designMode`) easier, as now it's decoupled from
`<input>` and `<textarea>` and separated from `EventHandler`, which is
quite a busy file.
This is really bare bone as we only support the `xyz-d50` color space
for the moment.
It makes us pass the following WPT tests:
- css/css-color/predefined-016.html
- css/css-color/xyz-d50-001.html
- css/css-color/xyz-d50-002.html
CSS Syntax 3 (https://drafts.csswg.org/css-syntax) has changed
significantly since we implemented it a couple of years ago. Just about
every parsing algorithm has been rewritten in terms of the new token
stream concept, and to support nested styles. As all of those
algorithms call into each other, this is an unfortunately chonky diff.
As part of this, the transitory types (Declaration, Function, AtRule...)
have been rewritten. That's both because we have new requirements of
what they should be and contain, and also because the spec asks us to
create and then gradually modify them in place, which is easier if they
are plain structs.
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.
Now we can register jobs and they will be executed on the event loop
"later". This doesn't feel like the right place to execute them, but
the spec needs some updates in this regard anyway.
There is an issue where gifs with many frames cannot be loaded, as each
bitmap is sent over IPC using a separate file descriptor, and there is
limit on the maximum number of descriptors per IPC message. Thus, trying
to load gifs with more than 64 frames (the current limit) causes the
image decoder process to die.
This commit introduces the BitmapSequence class, which is a thin wrapper
around the type Vector<Optional<NonnullRefPtr<Gfx::Bitmap>>> and
provides an IPC encode/decode routine that collates all bitmap data into
a single buffer so that only a single file descriptor is required per
IPC transfer, even if multiple frames are being sent.
We had numerous NiH-based implementations of audio formats and metadata
that we now no longer need because we either don't make use of the code,
or we replaced its implementation by FFmpeg.
This loader supports whatever format libavformat and libavcodec can
handle. Currently only seekable streams are supported, and we still have
some limitations as to the number of channels and sample format.

The vcpkg install is handled through an action to run vcpkg install with
the private --x-install-root flag that their CMake toolchain file uses
to install dependencies into a build-time directory.
The build assumed QT or AppKit are the only build UI frameworks. This
extends the default assumption away from that to start experimenting
with building on other platforms.
The `gn` build did not generate the CMake configuration file for the
backtrace module. Update the rules to configure the generated macros
mirroring the CMake build.
The file is not committed to disk until the close which occurs at the
termination of the scope. Extract the `rename` to outside the scope
allowing this to work on Windows. The `download_file` utility downloads
a file in the `gn` build.
Depending on usage, `@layer` has two forms, with two different CSSOM
types. One simply lists layer names and the other defines a layer with
its contained rules.
