Pages like the new tab page, error page, etc. all belong solely to
Ladybird, but are scattered across a couple of subfolders in Base. This
moves them all to Base/res/ladybird.
When a QObject subclass (widgets, etc.) are provided a parent, then
ownership of that object is passed to the parent. Similarly, objects
added to a QLayout are owned by the layout.
Thus, do not store these objects in an OwnPtr.
QString is UTF-16, thus QString::size returns the number of UTF-16 code
units. Thus, we would fail to perform, for example:
ak_string_from_qstring(QString("😀"));
Which is 2 UTF-16 code units, but 4 UTF-8 code units.
There's no need for 2 overloads for String and DeprecatedString, we can
just use a StringView. This also avoids some cases of needlessly
allocating a DeprecatedString from a StringView when calling this
method.
Ladybird on Serenity currently only uses F12, and on other platforms
only uses ctrl+shift+I. Most browsers support both hotkeys, so let's do
the same for consistency.
Note that the AppKit chrome cannot support both shortcuts. macOS does
not allow setting multiple "key equivalent" strings on an action. There
are some questionable hacks we could do to support this eventually, but
for now, just ctrl+shift+I is supported on macOS.
It is currently a bit messy to pass these options along from main() to
where WebContent is actually launched. If a new flag were to be added,
there are a couple dozen files that need to be updated to pass that flag
along. With this change, the flag can just be added to the struct, set
in main(), and handled in launch_web_content_process().
In order for same-origin NavigableContainers (iframe, frame, embed, ...)
and window.open() WindowProxies to have the proper JS access to their
embedder/opener, we need to host multiple top level traversables in the
same WebContent process. As a first step, make WebContent::PageHost hold
a HashMap of PageClient objects, each holding their own Web::Page that
represents a TraversableNavigable's API surface with the UI process.
The `page_did_request_scroll_to` API takes a CSS position, and thus
callers should not scale to device pixels before invoking it. Instead,
align this API with (most) other PageHost APIs which scale to device
pixels before sending the corresponding IPC message.
In the AppKit chrome, convert the provided device pixel position to a
widget position.
This matches the negation of the vertical scroll delta value. This makes
the scroll events behave as follows on macOS:
Natural scrolling enabled:
* Scrolling up on the trackpad scrolls down on the page.
* Scrolling right on the trackpad scrolls left on the page.
Natural scrolling disabled:
* Scrolling up on the trackpad scrolls up on the page.
* Scrolling right on the trackpad scrolls right on the page.
This was used to provided base functionality for model-based chromes for
viewing the DOM and accessibility trees. All chromes now use the WebView
inspector model for those trees, thus this class is unused.
When the `--dump-failed-ref-tests` flag is provided, screenshots of the
actual and reference pages will be placed in
`Build/lagom/ladbybird/test-dumps`. This makes it a lot easier to spot
what's wrong with a failing test. :^)
We call [NSApp activateIgnoringOtherApps:YES] to ensure the application
is brought into view and focused when launched from a terminal. But in
a macOS environment, we're better off using the `open` command to launch
the application (in which case, it does take foreground focus).
We now create a WorkerAgent for the parent context, which is currently
only a Window. Note that Workers can have Workers per the spec.
The WorkerAgent spawns a WebWorker process to hold the actual
script execution of the Worker. This is modeled with the
DedicatedWorkerHost object in the WebWorker process.
A start_dedicated_worker IPC method in the WebWorker IPC creates the
WorkerHost object. Future different worker types may use different IPC
messages to create their WorkerHost instance.
This implementation cannot yet postMessage between the parent and the
child processes.

This allows Ladybird to be the default browser on macOS, and allows for
opening some file types (.html, .svg, .md, etc.) with Ladybird.
Note this currently only works in the GN build (and thus the Qt chrome).
The CMake build does not set up the Resources directory properly for
macOS to run the Ladybird app without $SERENITY_SOURCE_DIR set.
If PulseAudio is available, the Qt6 audio plugin will never be used. So
let's remove it from the build.
Note that on macOS, the Qt6 audio plugin will be used if the Qt chrome
is enabled. Otherwise, Audio Unit will be used for the AppKit chrome.
This follows the pattern for the other services spawned by WebContent.
The notable quirk about this service is that it's actually spawned by
the ImageCodecPlugin rather than in main.cpp in the non-Android port.
As a result we needed to do some ifdef surgery to get all the pieces
in place. But we can now load images in the Android port again :^).
Instead of relying on AK_OS_LINUX, actually use the more accurate
HAS_ACCELERATED_GRAPHICS define to figure out if we should try to use
the generic LibAccelGfx GPU painter.
This patch brings a service to handle image decompression. With it comes
security enhancement due to the process boundary. Indeed, consequences
of a potential attack is reduced as only the decoder will crash without
perturbing the WebContent process.
It also allows us to display pages containing images that we claim to
support but still make us crash, like for not-finished-yet decoders.
As an example, we can now load https://jpegxl.info/jxl-art.html without
crashing the WebContent process.
