Enforce the use of the CPU backend in test mode to ensure that ref-tests
produce consistent results across different computers, as this
consistency cannot be achieved with the GPU backend.
This resolves a bug where if you opened a link in a new tab and quickly
went back to the original, the navigation buttons would update for the
new page shortly after.
Previously, the browser would crash when opening a task manager window
with the `--enable-qt-networking` flag set because we were passing the
default WebContentOptions to the underlying WebContentView.
This change adds a `--certificate` option to both WebContent and
WebWorker, which allows one or more custom root certificate paths to be
specified. Certificates are then loaded from these paths when Qt
networking is used.
This allows WPT tests that require a https connection to be run locally
with Qt networking.
We were not doing anything with the SwipeRefreshLayout, and it
interfered with touch events. We may want to bring this back at some
point? But probably only after we handle Android scrolling correctly.
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.
Using Qt networking when running web platform tests improves
performance significantly. The time to run the subset of tests we run
on CI drops from 21.9 seconds to 8.2 seconds on my machine.
This commit replaces all TLS connection code with wolfssl.
The certificate parsing code has to remain for now, as wolfssl does not
seem to have any exposed API for that.
Previously, new tabs always had the `auto` color scheme, regardless of
what the user has selected before.
Replace the 3 individual slots with a `set_preferred_color_scheme`
method.
LibWebView uses the Application object in WebContentClient.cpp, so we
need one to exist. It doesn't really do anything, since we never add
processes to it, but it just has to exist.
This updates the Android WebViewImplementationNative to match changes
made in commit 5285e22f2a.
We remove the async_set_viewport_rect call because the parent
ViewImplementation::handle_resize call does that for us.
The current version of the Android NDK uses Clang 17, which uses the
name c++2b instead of c++23.
This is the same flag we use in Meta/gn/build/BUILD.gn for macOS.
It looks like some things have moved around since the last time the
Android build worked. So, update the incorrect paths to point to where
they should.
This ensures that vcpkg downloads and builds all dependencies for
Android. We add it as a CMAKE_TOOLCHAIN_FILE that then chainloads the
Android NDK's toolchain file, as per the vcpkg documentation.
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.
Now instead of sending the position in which the user entered the
tooltip area, send just the text, and let the chrome figure out how to
display it.
In the case of Qt, wait for 600 milliseconds of no mouse movement, then
display it under the mouse cursor.
This allows developers on macOS to open Ladybird.app in Instruments.
Add some documentation for how to use the command as well. It is enabled
automatically when CMAKE_BUILD_TYPE is not Release or RelWithDebInfo.
By Setting setBordered propperty on header buttons to `Yes` this
path makes the whole button clickable. Previously the only the
icon was clickable, now it's easy to click.
This large commit also refactors LibWebView's process handling to use
a top-level Application class that uses a new WebView::Process class to
encapsulate the IPC-centric nature of each helper process.
In the upcoming changes, Skia painter will be switched to Metal backend,
so we can no longer assume `pitch = width * 4` while reading Gfx::Bitmap
that wraps IOSurface populated by writing into MTLTexture that has
padded scanlines.
Previously, autocomplete was cleared before the results for the current
query were retrieved. The new results would then be added when the
network request completed. This resulted in a noticable flicker. The
results are now updated when the request for the current query is
completed.
There is a small behavior change in that the query itself is no longer
included in the autocomplete dropdown unless the list would otherwise
be empty.
This was only put in place because on SerenityOS, we wanted to use the
pid of the WebContent process, rather than the peer pid for the socket.
When launching with SystemServer, this got annoying. However, now that
we only have the case that the UI process spawns processes, we can
get rid of this hack. This restores the ability to see WebContent
processes' statistics in the task manager widget.
This is the same behavior as RequestServer, with the added benefit that
we know how to gracefully reconnect ImageDecoder to all WebContent
processes on restart.
The placeholder text shows "Search or enter web address" which doesn't
tell the user about *how* the search will be performed. Other popular
open source browsers show the search engine that will be used. For
example:
Chromium: "Search **engine** or type a URL"
Firefox: "Search with **engine** or enter address"
This change changes the placeholder text of the location bar to show
"Search with **engine** or enter web address".
Using mmap-allocated memory for backing stores does not allow us to
benefit from using GPU-accelerated painting, because all the performance
increase we get is mostly negated by reading the GPU-allocated texture
back into RAM, so it can be shared with the browser process.
With IOSurface, we get a framebuffer that is both shareable between
processes and can be used as underlying memory for an OpenGL/Metal
texture.
This change does not yet benefit from using IOSurface and merely wraps
them into Gfx::Bitmap to be used by the CPU painter.
Allows WebContentClient to get pid of WebContent process right after
creation, so there is no window between forking and
notify_process_information() IPC response, when client doesn't know the
pid.
In the upcoming changes, we are going to switch macOS to using an
IOSurface for the backing store. This change will simplify the process
of sharing an IOSurface between processes because we already have the
MachPortServer running in the browser, and WebContent knows how to
locate the corresponding server.
LibLocale was split off from LibUnicode a couple years ago to reduce the
number of applications on SerenityOS that depend on CLDR data. Now that
we use ICU, both LibUnicode and LibLocale are actually linking in this
data. And since vcpkg gives us static libraries, both libraries are over
30MB in size.
This patch reverts the separation and merges LibLocale into LibUnicode
again. We now have just one library that includes the ICU data.
Further, this will let LibUnicode share the locale cache that previously
would only exist in LibLocale.
This patch adds a simple in-memory HTTP cache to each WebContent
process.
It's currently off by default (turn it on with --enable-http-cache)
since the validation logic is lacking and incomplete.
The location bar URL is no longer hidden when creating a new tab or
opening a new window that has an associated URL. Conversely, the
location bar is now always focused and the URL hidden when creating a
window or tab without an associated URL.
The location bar is focused when:
* Opening the browser from the command line with no URL arguments
* Opening a new tab (Ctrl+T)
* Opening a new window (Ctrl+N)
The location bar is not focused when:
* Opening the browser from the command line with one or more URLs
* Opening hyperlinks in a new tab
* Clicking a hyperlink with `target="_blank"`
This matches the behavior of other major browsers.
This adds a motion preference to the browser UI similar to the existing
ones for color scheme and contrast.
Both AppKit UI and Qt UI has this new preference.
The auto value is currently the same as NoPreference, follow-ups can
address wiring that up to the actual preference for the OS.
The URL is now not shown when a new tab is initially activated until
the location bar loses focus. This allows the user to see the location
bar placeholder text when opening a new tab. It also makes it easier to
paste URLs into the location bar after opening a new tab.
This commit adds the standard shortcuts for the Find Next and Find
Previous buttons on the find in page panel. These shortcuts are usually
F3 and Shift+F3 respectively, although Qt standard shortcuts may vary
across platforms.
On my system `QKeySequence::StandardKey::ZoomIn` includes both `Ctrl++`
and `Ctrl+=`, so explicitly adding the secondary `Ctrl+=` shortcut
ourselves results in an ambiguous shortcut error message being shown.
According to the Qt documentation the key bindings returned by
`QKeySequence::StandardKey::*` are platform specific, so we may still
need to add the secondary shortcut on some systems. Therefore, we now
check whether our secondary shortcut is already in the shortcut list
before adding it.
The placeholder text is there to prompt the user as to what could be
added in the address bar. The current text tells the user that they can
"Search or enter web address" even when the search setting is disabled.
When attempting to "Search" the user is instead sent to page ":", with
an error in the console:
WebContent(575249): (FIXME) Don't know how to navigate to :
This patch fixes this by checking whether the search feature is enabled
and setting the placeholder appropriately. This provides a slightly
better user experience.
Closes#132
Before we had HTTP::HeaderMap (which preserves multiple headers with the
same name), we collected multiple "Set-Cookie" headers and bundled them
together as a JSON array.
This was a huge hack, and now we can stop doing that, since LibWeb gets
access to the full set of headers now.
Instead of using a HashMap<ByteString, ByteString, CaseInsensitive...>
everywhere, we now encapsulate this in a class.
Even better, the new class also allows keeping track of multiple headers
with the same name! This will make it possible for HTTP responses to
actually retain all their headers on the perilous journey from
RequestServer to LibWeb.
If we get a suggestion from fontconfig, we try those fonts first, before
falling back on the hard coded list of known suitable fonts for each
generic family.
This makes WebView::Database wrap around sqlite3 instead of LibSQL. The
effect on outside callers is pretty minimal. The main consequences are:
1. We must ensure the Cookie table exists before preparing any SQL
statements involving that table.
2. We can use an INSERT OR REPLACE statement instead of separate INSERT
and UPDATE statements.
The "Enable Scripting", "Block Pop-ups" and "Enable Same-Origin Policy"
options are now set for every tab when toggled. They are also applied
to new tabs when they are created.
For some reason, moving the UI-specific CMake to its own files prevents
resource files from being copied to the Resource directory in the macOS
application. I'm not sure what the difference here is, but doing this
step during create_ladybird_bundle() works.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
This was no longer doing anything. We'll eventually want a way to pass
system default fonts to each WebContent process, but we don't need to
squeeze everything through this API that was really meant for Serenity's
very idiosyncratic font system.
This closes the window at WebContent process startup where we were
relying on Gfx::FontDatabase having some resolvable value in its default
font query.
This option skips attempting any chrome IPC which even with the
`--new-window` does not open a new browser process. This is annoying
when trying to compare browser options as opening a new window with
the currently running chrome ignores any options passed to the new
ladybird invocation.
This adds a `--experimental-cpu-transforms` option to Ladybird and
WebContent (which defaults to false/off).
When enabled the AffineCommandExecutorCPU will be used to handle
painting transformed stacking contexts (i.e. stacking contexts where
the transform is something other than a simple translation). The regular
command executor will still handle the non-transformed cases.
This is hidden under a flag as the `AffineCommandExecutorCPU` is very
incomplete now. It missing support for clipping, text, and other basic
commands. Once most common commands have been implemented this flag
will be removed.
LibWeb will need to use unbuffered requests to support server-sent
events. Connection for such events remain open and the remote end sends
data as HTTP bodies at its leisure. The browser needs to be able to
handle this data as it arrives, as the request essentially never
finishes.
To support this, this make Protocol::Request operate in one of two
modes: buffered or unbuffered. The existing mechanism for setting up a
buffered request was a bit awkward; you had to set specific callbacks,
but be sure not to set some others, and then set a flag. The new
mechanism is to set the mode and the callbacks that the mode needs in
one API.
This is to avoid including any LibProtocol header in Objective-C source
files, which will cause a conflict between the Protocol namespace and a
@Protocol interface.
See Ladybird/AppKit/Application/ApplicationBridge.cpp for why this
conflict unfortunately cannot be worked around.
Previously RS handled all the requests in an event loop, leading to
issues with connections being started in the middle of other connections
being started (and potentially blowing up the stack), ultimately causing
requests to be delayed because of other requests.
This commit reworks the way we handle these (specifically starting
connections) by first serialising the requests, and then performing them
in multiple threads concurrently; which yields a significant loading
performance and reliability increase.
Now that the chrome process is a singleton on all platforms, we can
safely add a cache to the CookieJar to greatly speed up access. The way
this works is we read all cookies upfront from the database. As cookies
are updated by the web, we store a list of "dirty" cookies that need to
be flushed to the database. We do that synchronization every 30 seconds
and at shutdown.
There's plenty of room for improvement here, some of which is marked
with FIXMEs in the CookieJar.
Before these changes, in a SQL database populated with 300 cookies,
browsing to https://twinings.co.uk/ WebContent spent:
19,806ms waiting for a get-cookie response
505ms waiting for a set-cookie response
With these changes, it spends:
24ms waiting for a get-cookie response
15ms waiting for a set-cookie response
We already have required this version for quite a while for Lagom,
Ladybird and Serenity. Now that we require it in all of our CMakeLists,
let's scrub for better ways of writing things.
This actually actives the underlying tab if needed. This wasn't an issue
previously, as new tabs were always created in already active windows.
But when new windows/tabs are requested from new Ladybird processes, we
need to actually activate those tabs.
For some reason, we occasionally receive a junk `info` pointer from the
CFSocketCallback we create for socket notifiers. Instead of capturing a
pointer to the local Core::Notifier for this `info` member, grab it from
the thread data instance based on the socket FD.
This was mostly seen when spamming new window requests to an existing
Ladybird process.
When we receive a LibCore event, we post an "application defined" Cocoa
event to the NSApp. However, we are currently only processing these from
`pump`, which is only invoked manually.
Instead, we should listen for the event that we've posted and process
the event queue at that time. This is much closer to how Qt's event loop
behaves as well with EventLoopImplementationQtEventTarget.
This shows the following actions:
* Reload Tab
* Duplicate Tab
* Move Tab
* Move to Start
* Move to End
* Close Tab
* Close Other Tabs
* Close Tabs to Left
* Close Tabs to Right
* Close Other Tabs
Rather than getting the tab name from the tab container. This resolves
an issue where ampersands were being introduced to the window title
when changing tabs.
This broke due to the way we now use posix_spawn under the hood. This
moves the handling of the callgrind option to the launcher helper where
we iterate over the candidate process paths, as we need to augment the
way we fork the process for callgrind based on those paths.
This also opens the door for running other processes under callgrind in
the future.
This really only affects headless-browser when it is linked with Qt. In
that case, it currently uses Qt networking by default and does not have
a flag to use RequestServer instead. Change the default to use RS so it
can undergo sanitized testing in CI.
The following command was used to clang-format these files:
clang-format-18 -i $(find . \
-not \( -path "./\.*" -prune \) \
-not \( -path "./Base/*" -prune \) \
-not \( -path "./Build/*" -prune \) \
-not \( -path "./Toolchain/*" -prune \) \
-not \( -path "./Ports/*" -prune \) \
-type f -name "*.cpp" -o -name "*.mm" -o -name "*.h")
There are a couple of weird cases where clang-format now thinks that a
pointer access in an initializer list, e.g. `m_member(ptr->foo)`, is a
lambda return statement, and it puts spaces around the `->`.
Previously the 'device independent pixels' (which consider scaling)
were used, and then scaling would be applied again when calculating the
screen width for CSS.
It previously resided in LibWebView to hide the details of launching a
singleton process. That functionality now lives in LibCore. By moving
this to Ladybird, we will be able to register the process with the task
manager.
This will be needed to collect statistics from processes that do not
have anything to do with LibWebView. The ProcessInfo structure must be
virtual to allow callers to add application-specific information.
Sometimes I like to play around with running Ladybird tests using full
blown Ladybird instead of just headless browser to interactively mess
around with the test page. One problem with this is that the internals
object is not exposed in this mode.
This commit supports this usecase by adding an option to specifically
expose the internals object without needing to run headless-browser
in test mode.
When launched with the new --enable-idl-tracing option, we now log
every call to web platform APIs declared via IDL, along with the
arguments passed.
This can be very helpful when trying to figure out what a site is
doing, especially if it's not doing what you'd expect.
When running with --log-all-js-exceptions, we will print the message
and backtrace for every single JS exception that is thrown, not just
the ones nobody caught.
This can sometimes be very helpful in debugging sites that swallow
important exceptions.
Before this change we had to keep session history on browser side to
calculate a url for back/forward/reload action.
Now, with a mature enough implementation of navigation algorithms from
the specification, there is no need to use
history on the browser side to calculate navigation URLs because:
- Traversable navigable owns session history that is aware of all
navigations, including those initiated by History API and Navigation
API
- TraversableNavigable::traverse_the_history_by_delta() uses
traversable's history to calculate the next URL based on delta, so
there is no need for UI to keep sesion history.
In the future, we will likely want to add a way to pull session history
from WebContent to make it browsable from the UI.
The previous name was extremely misleading, because the call is used for
pushing or replacing new session history entry on chrome side instead of
only changing URL.
Instead of treating reloading as a regular navigation by using
load_url(), now we invoke a navigable reloading algorithm implemented
from the spec.
Now both reloading triggered from UI and location.reload() will use the
same code path.
On macOS, it's not trivial to get a Mach task port for your children.
This implementation registers the chrome process as a well-known
service with launchd based on its pid, and lets each child process
send over a reference to its mach_task_self() back to the chrome.
We'll need this Mach task port right to get process statistics.
Currently the `<select>` dropdown IPC uses the option value attr to
find which option is selected. This won't work when options don't
have values or when multiple options have the same value. Also the
`SelectItem` contained so weird recursive structures that are
impossible to create with HTML. So I refactored `SelectItem` as a
variant, and gave the options a unique id. The id is send back to
`HTMLSelectElement` so it can find out exactly which option element
is selected.
This adds a button on the right side of the location bar to create a new
tab.
Ideally, we would actually use QTabWidget::setCornerWidget to put this
button in the tab bar. But it is surprisingly difficult to make that
look nice on all platforms. Even if we ignore macOS, the CSS to make the
button look right on KDE Plasma may not work well on Gnome. So for now,
this location next to the location bar is horizontally the same that it
would be in the tab bar at least.
We currently do this already when the last tab is closed via the ctrl-W
shortcut. Move the logic for this to BrowserWindow::close_tab so that we
also close the window when the tab is closed via its close button.
By default, Qt will grow the width of a tab button to fit the title text
of the tab. For long titles or file:// URLs, this looks rather bad. This
sets a min/max tab width to prevent such infinite growth.
To do this, we have to subclass both QTabWidget and QTabBar, because the
functions to be called/overridden are protected.
If the left-hand side of the tab is already occupied with an audio state
button, we would add a second button to the right-hand side. Prevent
that by checking if the occupant is our audio state button.
