This implements most of the CloseWatcher API from the html spec.
AbortSignal support is unimplemented.
Integration with dialogs and popovers is also unimplemented.
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.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
This was used to convert markdown into HTML for display in the browser,
but no other browser behaves this way, so let's simplify things by
removing it.
(Yes, we could implement all kinds of "convert to HTML and display" for
every file format out there, but that's far outside the scope of a
browser engine.)
For some reason, WebContent fails to load simple sites like xkcd.com
without the Qt event loop, even when using RequestServer instead of the
Qt networking stack. The CMake build on Linux has the same issue if we
skip installing the Qt event loop. It's not clear why this is - whether
something depends on the Qt event loop, or if there's a bug in the Unix
event loop implementation.
This is, however, also needed to use the --enable-qt-networking feature.
EventSource allows opening a persistent HTTP connection to a server over
which events are continuously streamed.
Unfortunately, our test infrastructure does not allow for automating any
tests of this feature yet. It only works with HTTP connections.
Supporting unbuffered fetches is actually part of the fetch spec in its
HTTP-network-fetch algorithm. We had previously implemented this method
in a very ad-hoc manner as a simple wrapper around ResourceLoader. This
is still the case, but we now implement a good amount of these steps
according to spec, using ResourceLoader's unbuffered API. The response
data is forwarded through to the fetch response using streams.
This will eventually let us remove the use of ResourceLoader's buffered
API, as all responses should just be streamed this way. The streams spec
then supplies ways to wait for completion, thus allowing fully buffered
responses. However, we have more work to do to make the other parts of
our fetch implementation (namely, Body::fully_read) use streams before
we can do this.
The logic in this script was *intended* to use the system's default
compiler if it was sufficiently new, and only start searching for the
latest installed if the default was not suitable.
However, the `cxx` program does not exist on Unixes, so the version
check always failed. We should be using the standard `c++` program name
instead.
After this change, the `CC` and `CXX` environment variables will have to
be used if someone wants to force a newer compiler version.
No behavior change. No measurable performance different either.
(I tried `hyperfine 'Build/lagom/bin/image --no-output foo.webp'`
for a few input images before and after this change, and I didn't
see a difference. I also tried if moving both
Gfx::CanonicalCode::read_symbol() and
Compress::CanonicalCode::read_symbol() inline, and that didn't
help either.)
* Matches how the loader is organized
* `compress_VP8L_image_data()` will grow longer when we add actual
compression
* Maybe someone wants to write a lossy compressor one day
No behavior change.
Nobody uses this functionality. I used this code on my old 2007 ICH7
test machine about a year ago, but bare metal is a small aspect of the
project, so it's safe to assume that nobody really tests this piece of
code.
Therefore, let's drop this for good and focus on more modern hardware.
Xcode clang doesn't understand the -std=c++23 spelling yet, and this
is what CMake's `set(CMAKE_CXX_STANDARD 23)` translates to too.
Unbreaks building with Xcode clang on macOS.
This allows main UI processes created while there is a currently
running one to request a new tab or a new window with the initial urls
provided on the command line. This matches (almost) the behavior of
Chromium and Firefox.
Add a new IPC protocol between two UI processes. The main UI process
will create an IPC server socket, while secondary UI processes will
connect to that socket and send over the URLs and action it wants the
main process to take.
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 just moves the code to launch a single process such as SQLServer to
LibCore. This will allow re-using this feature for other processes, and
will allow moving the launching of SQLServer to Ladybird.
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.
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.
On Serenity, it's not trivial to extract the peer pid from a socket that
is created by SystemServer and then passed to a forked service process.
This patch adds an API to let the WebContent process notify the UI
directly, which makes the WebContent process show up in the Serenity
port's TaskManagerWidget. It seems that we will need to do something of
this sort in order to properly gather metrics on macOS as well, due to
the way that self mach ports work.
We were able to keep LibCoreMinimal a bit smaller as an object library,
but that is causing ODR violations in the fuzzer build (realistically,
should be an issue in all builds, but only the fuzzer actively complains
for some reason).
To make it a shared library, we have to add a couple more symbols to it,
and make LibCore publicly depend on it.
We were off-by-one when returning the result of parsing a quoted string
in Web::Fetch::Infrastructure::collect_an_http_quoted_string. Instead of
backtracking the lexer and consuming the backtracked string, do a simple
substring operation.
We have been dancing around circular dependencies between LibCore and
generated sources. For example, LibURL currently cannot depend on
LibUnicode because the LibUnicode generators depend on LibCore, and
LibCore depends on LibURL. LibTimeZone is in a similar situation.
To alleviate this, we can define the minimal sources that the code
generators need as an object library. This will allow the generators to
depend on this library, rather than the full LibCore.
JPEG2000 is the last image format used in PDF filters that we
don't have a loader for. Let's change that.
This adds all the scaffolding, but no actual implementation yet.
This is a fetching AO and is only used by LibWeb in the context of fetch
tasks. Move it to LibWeb with other fetch methods.
The main reason for this is that it requires the use of other LibWeb AOs
such as the forgiving Base64 decoder and MIME sniffing. These AOs aren't
available within LibURL.
These are standalone applications meant to be run by the user directly,
as opposed to other libexec processes which are programmatically forked
by the browser. To do this, we simply remove these processes from the
`ladybird_helper_processes` list. We must also explicitly list the
dependencies for these processes.
This does not implement any of the IDL methods, but GitHub requires the
interface exists to upload files via an <input type="file"> element.
Their JS handles uploads via this element and via drag-and-drop in one
function, and check if the uploaded file is `instanceof DataTransfer` to
decide how to handle it.
This patch implements and tests window.crypto.sublte.generateKey with
an RSA-OAEP algorithm. In order for the types to be happy, the
KeyAlgorithms objects are moved to their own .h/.cpp pair, and the new
KeyAlgorithms for RSA are added there.
This patch throws away some of the spec suggestions for how to implement
the normalize_algorithm AO and uses a new pattern that we can actually
extend in our C++.
Also update CryptoKey to store the key data.
Now that all input events are handled by LibWebView, replace the IPCs
which send the fields of Web::KeyEvent / Web::MouseEvent individually
with one IPC per event type (key or mouse).
We can also replace the ad-hoc queued input structure with a smaller
struct that simply holds the tranferred Web::KeyEvent / Web::MouseEvent.
In the future, we can also adapt Web::EventHandler to use these structs.
The Serenity chrome is the only chrome thus far that sends all input key
and mouse events to WebContent, including shortcut activations. This is
necessary for all chromes - we must give web pages a chance to intercept
input events before handling them ourselves.
To make this easier for other chromes, this patch moves Serenity's input
event handling to LibWebView. To do so, we add the Web::InputEvent type,
which models the event data we need within LibWeb. Chromes will then be
responsible for converting between this type and their native events.
This class lives in LibWeb (rather than LibWebView) because the plan is
to use it wholesale throughout the Page's event handler and across IPC.
Right now, we still send the individual fields of the event over IPC,
but it will be an easy refactor to send the event itself. We just can't
do this until all chromes have been ported to this event queueing.
Also note that we now only handle key input events back in the chrome.
WebContent handles all mouse events that it possibly can. If it was not
able to handle a mouse event, there's nothing for the chrome to do (i.e.
there is no clicking, scrolling, etc. the chrome is able to do if the
WebContent couldn't).
This will be used to transfer information about the parent context to
DedicatedWorkers and future out-of-process Worker/Worklet
implementations for fetching purposes. In order to properly check
same-origin and other policies, we need to know more about the outside
settings than we were previously passing to the WebWorker process.
