We were still missing the resources and the libraries inside the actual
bundle directory. Do it at install time to not make a mess of all the
rules. The gn build lists all the libraries in a massive list, which
is quite a pain. We can over-copy a few libraries like this to make the
install script a bit easier to follow.
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.
We already do this for headless-browser. There's no need to open any URL
other than about:blank when starting a WebDriver session. We should also
do this from WebDriver code, rather than in special logic in Browser's
main.cpp.
The issue noted in the removed comment no longer seems to apply. The URL
loaded here is triggered before WebDriver even issues the POST /session
command.
When we launch Ladybird, we currently:
1. Create a BrowserWindow, whose constructor navigates to the configured
new tab page URL.
2. Then navigate to either "about:blank" or whatever URL is provided via
the command line.
This patch removes step 2 and forwards the URL from the command line (if
any) to BrowserWindow. BrowserWindow's constructor then either navigates
to that URL or the new tab page URL.
Currently, if the JS console is open and tied to the last opened tab in
the browser window, it will prevent the main process from exiting when
the last tab is closed. This change explicitly closes that tab before
closing the window (if it's the last tab), allowing Qt to delete the
Tab object.
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.
This object is available as `window.internals` (or just `internals`) and
is only accessible while running in "test mode".
This first version only has one API: gc(), which triggers a garbage
collection immediately.
In the future, we can add more APIs here to help us test parts of the
engine that are hard or impossible to reach via public web APIs.
The Qt docs are not that clear, but to get the number of steps the
wheel was scrolled you divide by 120 (which when multiplied by
wheelScrollLines() gives the scroll offset).
Documentation says that pixelDelta() is not reliable across platforms
so always using angleDelta() should produce more predictable scrolling
behaviour.
Rather than directing mouse wheel events to the QAbstractScrollArea,
send them to the WebContent process, allowing it to determine if they
should be consumed by the element or used for page scrolling.
The implementation of this plugin is meant to eventually replace all
current audio plugins in Ladybird. The benefits over the current Qt-
based audio playback plugin in Ladybird are:
- Low latency: With direct access to PulseAudio, we can ask for a
specific latency to output to allow minimal delay when pausing or
seeking a stream.
- Accurate timestamps: The Qt audio playback API does not expose audio
time properly. When we have access directly to PulseAudio APIs, we can
enable their timing interpolation to get an accurate monotonically-
increasing timestamp of the playing audio.
- Resiliency: With more control over how the underlying audio API is
called, we have the power to fix most bugs we might encounter. The
PulseAudio wrappers already avoid some bugs that occur with QAudioSink
when running through WSLg.
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.
The logic for `EventLoopImplementationQt::pump()` caused calls to
`EventLoop::pump(PumpMode::DontWaitForEvents)` to not consume events
posted to the Qt event queue. This caused the window to be unresponsive
even when polling the event loop, if waiting was not desired.
If a URL is not valid we try navigating to https:// + the url. It's
better to ask AK::Url if it thinks the url is valid than put a big list
of prefixes here, with this obscure protocols like Gemini are now
recognised and with `--enable-lagom-networking` can be viewed in
Ladybird (thanks to #2218).
Now that all the classes for Ladybird are in the Ladybird namespace, we
don't need them named as Ladybird::FooBarLadybird. For the Qt-specific
classes, we can tack on a Qt at the end for clarity, but FontPlugin and
ImageCodecPlugin no longer have anything to do with Qt.
We were super inconsistent about this, with most "new" classes living in
the Ladybird namespace, while "old" ones were in the global namespace,
or even sitting in the Browser namespace.
Ladybird's RequestServer needs to depend on its generated IPC header
files to ensure they are generated before RequestServer is compiled,
which we currently bundle into LibWebView.
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
:^).
Re-organize our helper files here a bit, to make a clearer distinction
between Qt-specific helpers and generic non-serenity helpers.
A future commit will move Lagom specific code from LibSQL to ladybird
as well, so that we can see about future generic apis for spawning
helper procesess.
The spawn_helper_process method was introduced together with
get_paths_for_helper_process but was only ever used briefly to spawn
WebContent. Other helper processes (SqlServer, headless_browser etc)
are either execed or spawned with their own helpers & custom arguments.
The Qt relationship was removed in de31a8a4, so let's acknowledge that
and make it clearer to potential non-Qt ports that this file is usable
by them :^).
Rather than set a hacky scale factor on our QIconEngine, just set the
icon size for the toolbar icons. This avoids the icons being
unnecessarily scaled in other places (i.e. the context menu).
In order to follow spec text to achieve this, we need to change the
underlying representation of a host in AK::URL to deserialized format.
Before this, we were parsing the host and then immediately serializing
it again.
Making that change resulted in a whole bunch of fallout.
After this change, callers can access the serialized data through
this concept-host-serializer. The functional end result of this
change is that IPv6 hosts are now correctly serialized to be
surrounded with '[' and ']'.
Now that we no longer use QFont from LibWeb, we can also stop using
QGuiApplication in the WebContent process entirely.
This removes a whole bunch of unnecessary work from the event loop,
and also allows nice things like running headless-browser while
*actually* headless. :^)
