This aligns our behaviour closer to other browsers, which
_mostly_ consider file scheme URLs as opaque. For test
purposes, allow overriding this behaviour with a commandline
flag.
We currently always save screenshots to the Downloads folder. We will
now always ask for a save location.
This will just let an upcoming feature to save images from web pages
behave the same way. We will want the user to be able to choose a file
name, since the file name from the URL might be nonsense or already
exist.
We used to have several of our own window types to close. We now only
have Tab windows. Our delegate handler is invoked even for windows such
file picker modals. The result was that we would close the modal window,
but the application would be left in a modal-active state.
We now behave like Safari. If cmd+w is pressed while a file picker modal
is open, no window is closed, and an error beep is played by AppKit.
Add a thread-safe deferred_invoke() API on WeakEventLoopReference that
queues work onto the owning thread's event queue and wakes that thread
via EventLoopManager hooks. This avoids calling wake() from foreign
threads during teardown.
Implement current_thread_handle()/wake_thread() in each backend and
track per-thread data so handles are validated before waking:
- Unix: wake via per-thread wake pipe
- Windows: wake via thread wake event
- macOS: wake via stored CFRunLoopRef
- Qt: wake via event target or QEventLoop::wakeUp()
- Android: wake via stored ALooper
The base class deferred_invoke() adds work to the thread event queue
and calls wake(), but that's not sufficient for CFRunLoop. We also
need to signal the deferred_source via CFRunLoopSourceSignal() so the
run loop knows to call its perform callback which processes the queue.
Without this signal, deferred invocations posted from other threads
(such as IPC I/O threads) would not be processed, causing deadlocks
when waiting for sync IPC responses.
wake() was using CFRunLoopGetCurrent() which returns the calling
thread's run loop. When called from an I/O thread to wake the main
thread's event loop, this would wake the wrong run loop.
Fixed by using the stored m_impl->run_loop which is captured at
construction time and refers to the event loop's owning thread.
Once upon a time, we needed the UI-specific event loops outside of the
UI process. This is no longer the case. Let's move the event loops back
to the UI folder to remove the awkward interface library we were left
with.
When a new tab is created, the location bar should automatically
receive keyboard focus so users can immediately start typing a URL.
However, the onURLChange callback was stealing focus back to the
web view when loading the new tab page.
This fix:
1. Calls focusLocationToolbarItem when activating a new tab
2. Prevents onURLChange from stealing focus when loading the new
tab page URL
Fixes#1512
This prevents the AppKit UI from sending unknown MIME types to LibWeb,
where we would previously blindly dereference the result of parsing the
MIME string. We now ignore unknown MIME types as well.
Clipboard handling largely has nothing to do with the individual web
views. Rather, we interact with the system clipboard at the application
level. So let's move these implementations to the Application.
This lets us avoid each UI needing to handle link clicks directly, and
lets actions stored in LibWebView avoid awkwardly going through the link
click callbacks to open URLs.
By migrating the debug menu to LibWebView, the AppKit and Qt UIs are now
in sync - the AppKit UI was previously missing some actions.
Further, this inadvertently fixes bugs around applying debug settings to
new web views, especially across site-isolated processes. We were
previously not applying settings appropriately; this now "just works" in
the LibWebView infra.
This migrates all duplicated context menus from the UIs to LibWebView.
The context menu actions are now largely handled directly in LibWebView,
with some UI-specific callbacks added to display e.g. confirmation
dialogs.
Actions that only ever apply to a specific web view are stored on the
ViewImplementation itself. Actions that need to be dynamically applied
to the active web view are stored on the Application.
This replaces the --devtools-port flag with a --devtools flag, which
optionally accepts a port. If the --devtools flag is set, we will now
automatically launch the DevTools server.
You would have to just know that you need to define the constructor with
this declaration. Let's allow subclasses to define constructors as they
see fit.
This is causing errors on the WPT runner, which does not have a display
output. To do this requires shuffling around the Main::Arguments struct,
as we now need access to it from overridden WebView::Application methods
after construction.
We currently create a separate headless-browser application to serve two
purposes:
1. Allow headless browsing to take a screenshot of a page or print its
layout tree / internal text.
2. Run the LibWeb test framework.
This patch migrates (1) to the main Ladybird executable. The --headless
flag enables this mode. This matches the behavior of other browsers, and
means we have one less executable to ship at distribution time.
We want to avoid creating too many AppKit / Qt facilities in headless
mode. So this involves some shuffling of application init to ensure we
don't create them until after we've parsed the command line arguments.
Namely, we avoid creating the NSApp in AppKit and QCoreApplication in
Qt. Doing so also requires that we don't create the application event
loop until we've parsed the command line as well, because the loop we
create depends on whether we're creating those UI facilities.
This removes the old autoplay allowlist file in favor of the new site
setting. We still support the command-line flag to enable autoplay
globally, as this is needed for WPT.
This adds a WebView::Settings class to own persistent browser settings.
In this first pass, it now owns the new tab page URL and search engine
settings.
For simplicitly, we currently use a JSON format for these settings. They
are stored alongside the cookie database. As of this commit, the saved
JSON will have the form:
{
"newTabPageURL": "about:blank",
"searchEngine": {
"name": "Google"
}
}
(The search engine is an object to allow room for a future patch to
implement custom search engine URLs.)
For Qt, this replaces the management of these particular settings in the
Qt settings UI. We will have an internal browser page to control these
settings instead. In the future, we will want to port all settings to
this new class. We will also want to allow UI-specific settings (such as
whether the hamburger menu is displayed in Qt).
The "disable DevTools" button looked like a "close this notification"
button to me, and although a tooltip was set, it only showed up
immediately on the AppKit UI and not the Qt version.
This makes the behavior of clicking the disable button a lot clearer by
showing a button with "Disable" as its title.
LibWebView now knows how to launch RequestServer and ImageDecoderServer
without help from the UI, so let's move ownership of these services over
to LibWebView for de-duplication.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
