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 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.

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 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.
This commit includes only fetching the DOM tree from the WebContent
process and displaying it in an NSOutlineView. The displayed tree
includes some basic styling (e.g. colors).
This function used to live in AndroidPlatform.cpp, but was removed
during the transition to the new app. We still need to extract the
assets from the tarball that CMake creates. At least, until we come
up with a generic "Resource" concept in LibCore.
Timers run in their own thread, to take advantage of existing Java
Executor features. By hooking into ALooper, we can spin the main
Activity's UI thread event loop without causing a fuss, or spinning the
CPU by just polling our event loop constantly.
This allows our WebViewImplementationNative class to paint into an
Android Bitmap class from the onDraw() view event. We also set the
viewport geometry from the view since we're setting the Kotlin Bitmap
at the same time.
This ports over the `LADYBIRD_USE_LLD` option from the standalone
Ladybird build and generalizes it to work for mold as well: the
`LAGOM_USE_LINKER` variable can be set to the desired name of the
linker. If it's empty, we default to trying LLD and Mold on ELF
platforms (in this order).
This template app from Android Studio should hopefully be more fun to
work on than the Qt wrapped application we were using before. :^)
It currently builds the native code using gradle rules, and has a stub
WebViewImplementationNative class that will wrap a c++ class of the same
name that inhertis from WebView::ViewImplementation. Spawning helper
processes and creating proper views in Kotlin is next on the list.
These classes are used as-is in all chromes. Move them to LibWebView so
that non-Serenity chromes don't have to awkwardly reach into its headers
and sources.
This adds menu items to open an interactive JavaScript console for a web
page. This more or less mimics the Qt implementation of the console.
Hooks are included to tie the lifetime of the console window with the
tab it belongs to; if the tab is closed, the console window is closed.
Without setting the --resources flag, headless-browser defaults to /res
for all resources it tries to find, including the theme. It will not
find this path on Lagom, so our attempt to load the default theme does
not accomplish anything.
This adds an alternative Ladybird chrome for macOS using the AppKit
framework. Just about everything needed for normal web browsing has
been implemented. This includes:
* Tabbed, scrollable navigation
* History navigation (back, forward, reload)
* Keyboard / mouse events
* Favicons
* Context menus
* Cookies
* Dialogs (alert, confirm, prompt)
* WebDriver support
This does not include debugging tools like the JavaScript console and
inspector, nor theme support.
The Qt chrome is still used by default. To use the AppKit chrome, set
the ENABLE_QT CMake option to OFF.
By running ctest -C Integration -R WPT, you can run WPT. Adding just
-C Integration will run all other tests *and* the WPT test.
Also add support for ./Meta/serenity.sh test lagom WPT to serenity.sh
Non-Qt chromes will want to use the same Info.plist and bundle info as
the Qt chrome. This patch puts the CMake setup for the bundle into a
function that non-Qt chromes may call in their CMakeLists.txt. The Qt
chrome calls it automatically.
We weren't installing a lot of generated sources for the top level Lagom
build or for LibWeb, making it impossible to use LibWeb from a
find_package. ...And also Kernel/API/KeyCode.h, which is included by
no less than 8 different files in Userland/Libraries. We also weren't
installing any Ladybird header files.
This will help a lot with developing chromes for different UI frameworks
where we can see which helper classes and processes are really using Qt
vs just using it to get at helper data.
As a bonus, remove Qt dependency from WebDriver.
With the CMake build, the ladybird binary ends up in
$build/bin/ladybird.app/Contents/MacOS. Which is a bit unfortunate for
a few reasons, but the main one is that --enable-lagom-networking
doesn't work with ./Meta/serenity.sh run lagom ladybird.
Let's copy the file to the expected location. There's very likely better
solutions we can use in the future.
Previously, a QTimer was used to start processing of our event queue in
the main Qt event loop. Unfortunately, QTimers are not thread-safe, and
disallow starting of a timer from a different thread than it was
created in.
Instead, use a dummy QObject to post a custom QEvent to the main loop
from whatever thread we like, and process our event queue when it is
received by our dummy object.
LibTLS still can't access many parts of the web, so let's hide this
behind a flag (with all the plumbing that entails).
Hopefully this can encourage folks to improve LibTLS's algorithm support
:^).
Rather than render the icons to a 16x16 bitmap, keep them as vector
graphics and render them on request. This keeps the icons crisp on high
DPI displays.
We don't need the extra gradle files in our sources, the Qt CMake
integration will generate suitable ones for us.
Make sure that assets is always a folder, so that we can get the proper
layout for the ladybird-assets.tar.gz and CMake doesn't create a gzip
file with the name "assets".
Fix up the AndroidPlatform file and make sure it's linked into all the
applications that need it. Also make sure to copy all the application
shared libraries into the ladybird APK so that when we make them into
proper Services, the libs are already there.
Doing this removes the qt6-svg dependency and allows our rasterizer to
be used for these little icons (and happens to be a fair bit smaller
than the old SVGs).
This creates (and installs upon WebContent startup) a platform plugin to
play audio data.
On Serenity, we use AudioServer to play audio over IPC. Unfortunately,
AudioServer is currently coupled with Serenity's audio devices, and thus
cannot be used in Ladybird on Lagom. Instead, we use a Qt audio device
to play the audio, which requires the Qt multimedia package.
While we use Qt to play the audio, note that we can still use LibAudio
to decode the audio data and retrieve samples - we simply send Qt the
raw PCM signals.
