Don't put them in bin/ and then copy them to the bundle dir later, as
this means that they only get updated in the bundle directory if the
Ladybird binary itself needs updated. Which is not a fun workflow if you
are working on WPT and want to hack on the WebDriver binary.
QUrl::toString reverses the Unicode->ASCII conversion that already
occurred here. The text of m_location_edit is already in the format we
expect, so let's just convert QString->AK::URL directly, instead of
taking the detour QString->QUrl->AK::URL
Some Wayland compositors have support of fractional-scale-v1 protocol.
The protocol allows compositor to announce a preferred fractional scale
on a per-wl_surface basis. Qt forwards these Wayland events to an
application using a usual DevicePixelRatioChange event. However, in
contrast to the other platforms, this DevicePixelRatioChange event is
issued directly on widgets and not screens. Additionally, the exact
fractional scale is stored in QWindow object and not the current screen.
Note that in theory it is possible to obtain per-screen fractional
scaling on Wayland by interpolating data provided by wl_output and
xdg_output events but qtwayland does not do that.
If fractional-scale-v1 is not available, qtwayland will still fire
per-Widget DevicePixelRatioChange events, but, obviously, with the
per-screen possibly larger ceiled scaling.
This whole thing makes handling DPI changes on Wayland really simple.
All we need to do is to intercept DevicePixelRatioChange events firing
on QWindow objects and call the old device_pixel_ratio_changed handler
with the window's devicePixelRatio(). The only caveat here is not forget
to always set QWidget's parent before calling devicePixelRatio() on it.
Previously, on systems where pressing Enter would generate "\r\n", only
the '\r' character was being sent to the event handler. This change
ensures consistent behavior across platforms regardless of their native
line ending characters.
The IPC layer between chromes and LibWeb now understands that multiple
top level traversables can live in each WebContent process.
This largely mechanical change adds a billion page_id/page_index
arguments to make sure that pages that end up opening new WebViews
through mechanisms like window.open() still work properly with those
extra windows.
We currently bundle AK with LibCore on Lagom. This means that to use AK,
all libraries must also depend on LibCore. This will create circular
dependencies when we create LibURL, as LibURL will depend on LibUnicode,
which will depend on LibCore, which will depend on LibURL.
Instead of spawning these processes from the WebContent process, we now
create them in the Browser chrome.
Part 1/N of "all processes are owned by the chrome".
These IPCs are different than other IPCs in that we can't just set up a
callback function to be invoked when WebContent sends us the screenshot
data. There are multiple places that would set that callback, and they
would step on each other's toes.
Instead, the screenshot APIs on ViewImplementation now return a Promise
which callers can interact with to receive the screenshot (or an error).
According to Qt documentation, destruction of a QObject's children may
happen in any order. In our case, the Tab's WebContentView is deleted
before its InspectorWidget. The InspectorWidget performs cleanup on that
WebContentView in its destructor; this causes use-after-free since it
has already been destroyed.
From reading Qt threads, if a particular destruction order is required,
it is okay to enforce that order with manual `delete`s. This patch does
so with the InspectorWidget to ensure it is deleted before the
WebContentView. Qt's object ownership is okay with this - it will remove
the InspectorWidget from the Tab's children, preventing any double
deletion.
With this change, chrome no longer has to ask the WebContent process
to paint the next frame into a specified bitmap. Instead, it allocates
bitmaps and sends them to WebContent, which then lets chrome know when
the painting is done.
This work is a preparation to move the execution of painting commands
into a separate thread. Now, it is much easier to start working on the
next frame while the current one is still rendering. This is because
WebContent does not have to inform chrome that the current frame is
ready before it can request the next frame.
Additionally, as a side bonus, we can now eliminate the
did_invalidate_content_rect and did_change_selection IPC calls. These
were used solely for the purpose of informing chrome that it needed to
request a repaint.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:

$ perl -pie 's/\bDeprecatedString\b/ByteString/g;

If the Inspector widget already exists, be sure to inspect the page when
it is re-opened. However, this should be a no-op if the page was already
inspected (as any existing Inspector will be reset if a new page load
began).
Note this is not an issue in the AppKit chrome.
It was a bit short-sighted to combine the tag and attribute names into
one string when the Inspector requests a context menu. We will want both
values for some context menu actions. Send both names, as well as the
attribute value, when requesting the context menu.
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.
