Instead of starting a new headless-browser for every layout & text test,
headless-browser now gets a mode where it runs all the tests in a single
process.
This is massively faster on my machine, taking a full LibWeb test run
from 14 seconds to less than 1 second. Hopefully it will be a similarly
awesome improvement on CI where it has been soaking up more and more
time lately. :^)
This looks a lot more "at home" than usual pixel art logo on
non-SerenityOS systems. :^)
Also, stop using site favicons as the app icon as that made it
annoyingly hard to find Ladybird in task switchers sometimes.
This allows us to create "text tests" in addition to "layout tests".
Text tests work the same as layout tests, but dump the document content
as text and exit upon receiving the window "load" event.
Previously, calling `.right()` on a `Gfx::Rect` would return the last
column's coordinate still inside the rectangle, or `left + width - 1`.
This is called 'endpoint inclusive' and does not make a lot of sense for
`Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would
return 4 as its right side. This same problem exists for `.bottom()`.
This changes `Gfx::Rect` to be endpoint exclusive, which gives us the
nice property that `width = right - left` and `height = bottom - top`.
It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly
the same.
All users of `Gfx::Rect` have been updated accordingly.
The goal here is to reduce the amount of WebContent client APIs that are
duplicated across every ViewImplementation. Across our three browsers,
we currently:
Ladybird - Mix some AK::Function callbacks and Qt signals to notify
tabs of WebContent events.
Browser - Use only AK::Function callbacks.
headless-browser - Drop most events on the floor.
Instead, let's only use AK::Function callbacks across all three browsers
to propagate events to tabs. This allows us to invoke those callbacks
directly from LibWebView instead of all three browsers needing to define
a trivial `if (callback) callback();` override of a LibWebView virtual
function. For headless-browser, we can simply not set these callbacks.
As a first pass, this only converts WebContent events that are trivial
to this approach. That is, events that were simply passed onto the tab
or handled without much fuss.
This is to match Browser, where ownership of all "subwidgets" is placed
on the tab as well. This further lets us align the web view callbacks to
match Browser's OOPWV as well, which will later let us move them into
the base LibWebView class.
Note that the real implementations of these functions are:
notify_server_did_output_js_console_message
notify_server_did_get_js_console_messages
Which have the same method bodies as these unused variants.
The implementations of handle_web_content_process_crash and
take_screenshot are exactly the same across Browser and Ladybird. Let's
reduce some code duplication and move them to LibWebView.
Previously, we were doing mapToGlobal() via the Tab widget, but the
widget position was actually relative to the WebContentView. This
meant context menus appeared slightly vertically offset from where
you clicked.
This just sets up the IPC to notify the browser process of context menu
requests on video elements. The IPC contains a few pieces of information
about the state of the video element.
While resizing, we now pad the shared bitmap allocations with 256 pixels
extra in both axes. This avoids churning through huge allocations for
every single resize step.
We also don't reallocate at all when making the window smaller.
3 seconds after the user stops resizing, we resize the backing stores
again so they fit the window perfectly.
This fixes an unpleasant visual glitch when resizing the window.
When the user makes our QAbstractScrollArea larger, the scroll bars can
end up with negative values, which we were happily forwarding to the
WebContent process and asking it to paint the whole page at an offset.
This commit adds the common actions you'd expect to the Ladybird context
menu, arranged like so:
┌──────────────────────────────┐
│ Go Back Alt+Left │
│ Go Forward Alt+Right │
│ Reload Ctrl+R │
│ ──────────────────────────── │
│ Copy Ctrl+C │
│ Select All Ctrl+A │
│ ──────────────────────────── │
│ View Source Ctrl+U │
│ Inspect Element │
└──────────────────────────────┘
The asynchronous query execution keeps causing bugs with document.cookie
so let's make the SQL database backend default off until we can trust it
to do what we need.
This adds "Inspect Element" (currently the only entry) to the context
menu for the page, which will do what you expect (most of the time),
and bring up the Inspector with hovered element selected.
We should only rely on LibGfx to decode images for us, if LibGfx
can't decode an image that should be motivation to improve LibGfx,
not hidden by Qt picking up the slack :^)
While it's nice to see <img src="foo.svg"> suddenly work in Ladybird
after linking with the Qt SVG module, this is cheating.
We should implement SVG-as-image ourselves instead of relying on 3rd
party code to do it. :^)
For some reason, this was causing incomplete HTTP loads in some cases.
As an example, we would only load half of the "Ahem" CSS font from the
wpt.live server when running Acid3.
I only enabled pipelining in the first place because I assumed it would
be a performance boost, but it appears to do more than that.
I suppose there's a reason it's off by default (and most Qt API users
don't bother enabling it.)
We now load SVG icons (via the Qt resource system) and render them into
a QIcon (with normal and disabled variants) using system colors.
We also re-render them if the system color theme changes.
This instantly makes Ladybird look less foreign on my Linux box.
I drew the icons myself, and they could definitely be more optimized,
but this was my first time using Inkscape. :^)
The WebContent process behaves a bit awkwardly on macOS. When we launch
the process, we have to create a QGuiApplication to access system fonts.
But on macOS, doing so creates an entry in the Dock, and also causes the
WebContent to be focused. So if you enter cmd+Q without first focusing
the Ladybird GUI, WebContent is closed, while the Ladybird process keeps
running.
This shouldn't have been moved to EventLoopManager, as the manager is
global and one-per-process, and the implementation is one-per-loop.
This makes cross-thread event posting work again, and unbreaks
SoundPlayer (and probably other things as well.)
We currently query Qt for system fonts using QFont::setStyleHint(). The
docs from Qt have the following note regarding this API on X11:
Qt does not support style hints on X11 since this information is not
provided by the window system.
This prevents any monospace font from working on X11 systems. For now,
work around this by specifying the font-family for fonts which Qt has
listed as mapping to a CSS generic font-family.
Things such as timers and notifiers aren't specific to one instance of
Core::EventLoop, so let's not tie them down to EventLoopImplementation.
Instead, move those APIs + signals & a few other things to a new
EventLoopManager interface. EventLoopManager also knows how to create a
new EventLoopImplementation object.
Using QEventLoop works for everything but it breaks *one* little feature
that we care about: automatically quitting the app when all windows have
been closed.
That only works if you drive the outermost main event loop with a
QCoreApplication instead of a QEventLoop. This is unfortunate, as it
complicates our API a little bit, but I'm sure we can think of a way to
make this nicer someday.
In order for QCoreApplication::exec() to process our own
ThreadEventQueue, we now have a zero-timer that we kick whenever new
events are posted to the thread queue.
