Window origins in AppKit are the bottom-left position of the NSWindow,
relative to the bottom-left of the screen. So we must do some alignment
of the top-left position received from WebDriver.
We call ns_event_to_key_event for the NSFlagsChanged event as well. By
retrieving the isARepeat flag on those events, we are guaranteed to
throw an exception.
See:
https://developer.apple.com/documentation/appkit/nsevent/1528049-arepeat?language=objc
Raises an NSInternalInconsistencyException if sent to an
NSFlagsChanged event or other non-key event.
This abstraction will help us to support multiple IPC transport
mechanisms going forward. For now, we only have a TransportSocket that
implements the same behavior we previously had, using Unix Sockets for
IPC.
When a platform key press or release event is repeated, we now pass
along a `repeat` flag to indicate that auto-repeating is happening. This
flag eventually ends up in `KeyboardEvent.repeat`.
On the view-source page, generate anchor tags for any 'href' or 'src'
attribute value we come across. This handles both when the attribute
contains an absolute URL and a URL relative to the page.
This requires sending the document's base URL over IPC to resolve
relative URLs.
Our handling of left vs. right modifiers keys (shift, ctrl, etc.) was
largely not to spec. This patch adds explicit UIEvents::KeyCode values
for these keys, and updates the UI to match native key events to these
keys (as best as we are able).
If the user only presses the shift key, for example, we are required to
still send that event to WebContent and generate the corresponding JS
events. Unfortunately, NSApp does not inform us of these events via the
keyDown/keyUp methods. We have to implement the flagsChanged interface,
and track for ourselves what modifier keys were pressed or released.
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.
We don't create a ChromeProcess in headless-browser, so it is currently
not increasing it's open file limit. This is causing crashes on macOS,
which has a very low default limit.
This has been implemented in Qt for quite some time. This patch adds the
same feature to AppKit. This is needed to run many WPT subtests with the
AppKit chrome. This is also needed to handle window.open, target=_blank
link clicks, etc.
This is overriding the URL passed to e.g. window.open and link clicks on
an <a target=_blank> element.
Note: This alone is not enough to support such use cases. We will also
need to actually implement opening child web views. But getting this fix
out of the way first makes that patch a bit simpler.
The main motivator here was noticing that --disable-sql-database did not
work with AppKit. Rather than re-implementing this there, move ownership
of these classes to WebView::Application, so that each UI does not need
to individually worry about it.
AppKit uses Private Use Area code points for a large collection of
functional keys (arrows, home/end, etc.). Re-assign them to 0 to avoid
tripping up WebContent's key handler.
Before this change, we were passing CGColorSpaceCreateDeviceRGB() to
CGImageCreate(), causing the system to assume that the image data is
in a device-specific RGB space without any color profile adjustments.
If your monitor is more vibrant than the assumed profile (for example,
a wide-gamut display), colors may appear over-saturated as there's no
correction applied for how the display actually renders those colors.
We now pass CGColorSpaceCreateWithName(kCGColorSpaceSRGB) instead,
which makes colors look the same in Ladybird as in other browsers. :^)
The AppKit Application class is responsible for launching all helper
processes. This had to be moved to a .cpp file because we were unable to
include headers with the Protocol namespace in .mm files, as they would
conflict with the Protocol interface defined by Apple.
Now that this namespace has been renamed to Requests, we can remove this
workaround.
This forwards all drag-and-drop events from the UI to the WebContent
process. If the page accepts the events, the UI does not handle them.
Otherwise, we will open the dropped files as file:// URLs.
The identifier "Protocol" is claimed by Objective-C and Swift for use
by the language's built-in protocol conformance feature, which is
similar to Rust traits or Java interfaces.
Rename LibProtocol -> LibRequests, and its namespace from Protocol to
Requests to accomodate this.
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).
To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.
There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
The default limit (at least on Linux) causes us to run out of file
descriptors at around 15 tabs. Increase this limit to 8k. This is a
rather arbitrary number, but matches the limit set by Chrome.
Skia painter is visibly faster than LibGfx painter and has more complete
CSS transforms support. With this change:
- On Linux, it will try to use Vulkan-backend with fallback to
CPU-backend
- On macOS it will try to use Metal-backend with fallback to
CPU-backend
- headless-browser always runs with CPU-backend in layout mode
If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
This change adds a `--use-lagom-networking` flag to the WebWorker
process. Qt networking is used if this flag isn't passed. The flag is
passed the UI launches the WebWorker process unless the Qt chrome is
being run with the `--enable-qt-networking` flag.
GPU painter that uses AccelGfx is slower and way less complete compared
to both default Gfx::Painter and Skia painter. It does not make much
sense to keep it, considering Skia painter already uses Metal backend on
macOS by default and there is an option to enable GPU-accelerated
backend on linux.
This call is used to inform the chrome that it should display a tooltip
now and avoid any hovering timers. This is used by <video> tags to
display the volume percentage when it is changed.
