Currently, on Serenity, we connect to WebDriver from the browser-side of
the WebContent connection for both Browser and headless-browser.
On Lagom, we connect from within the WebContent process itself, signaled
by a command line flag.
This patch changes Lagom browsers to connect to WebDriver the same way
that Serenity browsers do. This will ensure we can do other initializers
in the same order across all platforms and browsers.
There isn't a 1:1 equivalent for all ColorRoles between Qt and LibGfx,
but we can at least make an effort to translate the various QPalette
preferred colors.
This makes text selection look a lot more "native" in Ladybird. :^)
This patch replaces the usage of QPalette::PlaceholderText with
QPalette::Text with opacity reduced to roughly 50%. This fixes the non
highlighted spans having an extremely low contrast compared to the
background in dark mode.
LibGUI and WebDriver (read: JSON) API boundaries use DeprecatedString,
so that is as far as these changes can reach.
The one change which isn't just a DeprecatedString to String replacement
is handling the "null" prompt response. We previously checked for the
null DeprecatedString, whereas we now represent this as an empty
Optional<String>.
headless-browser currently uses its own PageClient to load web pages
in-process. Due to this, it also needs to set up a whole bunch of other
objects needed to run LibWeb, e.g. image decoders, request servers, etc.
This changes headless-browser to instead implement a WebView to launch
WebContent out-of-process. This implementation is almost entirely empty,
but can be filled in as-needed. For example, we may want to print
JavaScript console messages.
We should be able to run this locally, as long as ENABLE_LAGOM_LADYBIRD
is true, or if building ladybird from the ladybird source directory.
This removes a special case from the Lagom CI yml file.
The QNetworkReply::NetworkError enum mixes all kinds of errors into one
enum, HTTP errors, network errors, proxy errors, etc.
Instead of caring about it, we now say that HTTP requests were
successful if their response has any HTTP status code attached.
This allows LibWeb to display error pages when using Qt networking.
Instead of just calling JS::Value::to_string_without_side_effects() when
printing values to the console, have all the console clients use
the same JS::Print that the REPL does to print values.
This method leaves some things to be desired as far as OOM hardening
goes, however. We should be able to create a String in a way that
doesn't OOM on failure so hard.
Otherwise Qt would not find the wayland plugin it is instructed to use
via QT_QPA_PLATFORM, and would fall back to the second option, xcb,
which looks rather sad in a modern Wayland environment :^)
This feels like something that should be addressed upstream in nixpkgs
eventually.
This adds support for WebSocket subprotocols to WebSocket DOM
objects, with some necessary plumbing to LibWebSocket and its
clients.
See the associated pull request for how this was tested.
This allows the WebDriver to take advantage of the common helper process
spawning code when launching ladybird, and to not assume a particular
directory layout.
Use a list of executables to make sure that we don't miss any of the
applications used by Ladybird and its friends like WebDriver, and make
sure to install include all executables and their runtime dependencies.
Use the new get_paths_for_helper_process method in Ladybird to query
Qt for the runtime path of the current executable as well as the build
directory paths.
Previously when there was a very long url that spanned outside of the
address bar, the text shown would be the one starting from the very end
of the url instead of from the beginning, so you would be seeing the
query parameters for example, instead of the domain.
These changes will prevent duplication of code later when there will
also be the possibility to navigate to the homepage url as defined in
the settings on startup.
Don't use _exit() - this is a forceful exit that will bypass all exit
handlers. This includes AddressSanitizer, and will prevent ASan from
exiting the app with a fatal error code.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.
This will avoid loading starting about:blank page in places when we know
exactly what we want to load.
The opening in background part might be useful for future things like
file drops and right-click open in new tab.
Because TGA images don't have magic bytes as a signature to be detected,
instead assume a sequence of ReadonlyBytes is a possible TGA image only
if we are given a path so we could check the extension of the file and
see if it's a TGA image.
When we know the path of the file being loaded, we will try to first
check its extension, and only if there's no match to a known decoder,
based on simple extension lookup, then we would probe for other formats
as usual with the normal sniffing method.
This starts moving code equally shared between the OOPWV and Ladybird
WebContentView implementations to WebView::ViewImplementation, beginning
with the client state.
On many keyboards, Ctrl++ is actually Ctrl+Shift+=, and Ctrl+= makes
more sense as it's symmetric with Ctrl+-.
Both Firefox and Chrome already support this alternate shortcut,
so let's be nice and support it in Ladybird as well. :^)
This makes vector fonts load on macOS, where /usr/share/fonts doesn't
exist and Ladybird would only load the bitmap fonts from ./res/fonts
in the SerenityOS resource root directory.
Additionally, fonts in {/usr/share/local,~/.local}/fonts are now loaded
on Linux.
This patch also stubs out notify_server_did_get_accessiblity_tree in
ladybird since ViewImplementation now has it. However, this feature
is still immature, so just stubbing out in ladybird for now. Once we
have more robust support in Serenity (namely ARIA properties/state
and accessible names and descriptions) we can port this
functionality over.
This has been broken since the switch to the multiprocess architecture
(and even before then was very limited).
This restores the previous functionally and also implements the ability
to inspect individual elements (by selecting them in the tree view).
The inspector also now correctly updates when navigating between pages.
This allows us to use standard Serenity IPC infrastructure rather than
manually creating FD-passing sockets. This also lets us use Serenity's
WebDriver Session class, removing the copy previously used in Ladybird.
This ensures any changes to Session in the future will be picked up by
Ladybird for free.
Rather than manually launching the SQLServer process, use SQLClient's
new functionality to launch the server just once for all Ladybird
instances. Quit the SQLServer process when it no longer has any
connected clients.
When Ladybird exits, SQLServer can get stuck spinning at 100% CPU after
the socket connection is closed. This changes the client to quit the
event loop when that disconnect happens to ensure that SQLServer is
properly destroyed.
This adds a SQLServer binary for Ladybird to make use of Serenity's SQL
implementation. This has to use the same IPC socket handling that was
used to make WebContent and WebDriver work out-of-process.
Unlike Serenity, Ladybird creates a new SQLServer instance for each
Ladybird instance. In the future, we should try to make sure there is
only one SQLServer instance at a time, and allow multiple Ladybird
instances to communicate with it.
We now replace the current history entry if the page-load has been
caused because of a redirect. This makes it able to traverse the
history if one of the entries redirects you, which previously
caused an infinite history traversion loop.
Depends on https://github.com/SerenityOS/serenity/pull/16004
Similar to https://github.com/SerenityOS/serenity/commit/9782660. Unlike
Serenity's browser, this doesn't affect reloading the page, as Ladybird
refers to the History object for reloading (which is updated already on
page load). However, this URL is used for e.g. crash reporting, so let's
update it here as well.
WebContent now needs to interact with these dialogs asynchronously. This
updates WebContentView to hold a pointer to whatever dialog is open, and
implements the methods to interact with that dialog.
This adds a WebDriver binary for Ladybird to make use of Serenity's
WebDriver implementation. This has to use the same IPC socket handling
that was used to make WebContent work out-of-process. Besides that, we
are able to reuse almost everything from Serenity.
The WebDriver will pass the --webdriver-fd-passing-socket command line
option when it launches Ladybird. Forward this flag onto the WebContent
process, where it will create the WebDriverConnection for IPC.
Rather than needing to set another environment variable for WebDriver's
passing socket, let's forward these FDs by command line. This also moves
the creation of the WebContent connection to a helper function so that
the WebDriver connection can re-use it.
Previously, reloading went back to the first page loaded by
WebView::load() or WebView::load_html(), as they are the only methods
that modify m_url, which is what the reload loaded. Now we handle
reloads in Tab.cpp by simply loading the last entry in the m_history.
The hackish initial loading of about:blank was previously added to the
history, so you could go back to it (which wasn't very ergonomic). Now
we set the m_is_history_navigation flag before loading it so it doesn't
get added to the history.
Steps to reproduce:
1. Open the Cookie Clicker game in a tab.
2. Open another website in another tab and make that the current tab.
3. Observe how the window's title mentions Cookie Clicker.
Previously we were always pushing to history on the on_load_start
callback. Now we only do that if we are NOT navigating through the
history navigation (loading pages by going back/forward). This is what
the SerenityOS browser does:^)
We now emit a new signal for backward mouse button's mouseup and forward
mouse button's mouseup which is handled by going back and forward in the
history respectively:))
There's no point in busy-waiting for the condition to come true.
By passing the `WaitForMoreEvents` flag to `processEvents()`, we allow
Qt to block until it has something for us to react to.
This was extremely noticeable when waiting for large resources to
finish loading.
The slowdown is sometimes 5x, possibly more.
This is trivially confirmed by adding a large JS file to a page and
comparing the load time with a simple wget.
- Add Qt::Core, Qt::Gui, LibGfx, LibIPC, and LibJS to the ladybird
target, remove LibGL, LibSoftGPU, and LibWebSocket
- Add LibJS to the WebContent target, remove LibWebView
- Order them properly :^)
Regressed in https://github.com/SerenityOS/serenity/pull/15746.
Fixes#108.
There are no custom changes for Ladybird in the current copies of those
files, so we just need to ensure to keep Ladybird up to date for any
changes made upstream.

This fixes a build issue introduced by https://github.com/SerenityOS/serenity/pull/15736.
Qt can wrap any number of cookies into a single Set-Cookie header in the
network responses it gives us. We now use the QNetworkReply::header()
API to get a "cooked" list of the cookies, and then rewrap them in a
format suitable for LibWeb.
Sites that send multiple Set-Cookie headers in one response now work
a lot better. :^)
These didn't work, for two reasons:
1. Qt swallows all Tab key presses by default. We have to override
the event() function in order to receive them.
2. Qt transforms Shift+Tab into a fake "Backtab" key. We have to
undo this transformation and send Shift+Tab to WebContent.
