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.
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>.
The name "initial containing block" was wrong for this, as it doesn't
correspond to the HTML element, and that's specifically what it's
supposed to do! :^)
There is currently a memory leak with these file request objects due to
the callback on_file_request_finish referencing itself in its capture
list. This object does not need to be reference counted or allocated on
the heap. It is only ever stored in a HashMap until a response is
received from the browser, and it is not shared.
...and also for hit testing, which is involved in most of them.
Much of this is temporary conversions and other awkwardness, which
should resolve itself as the rest of LibWeb is converted to these new
types. Hopefully. :thousandyakstare:
Updating cookies through these hooks happens in one of two manners:
1. Through the Browser's storage inspector.
2. Through WebDriver's delete-cookies operation.
In (1), we should not restrict ourselves to being able to delete cookies
for the current page. For example, it's handy to open the inspector from
the welcome page and be able to delete cookies for any domain.
In (2), we already are only interacting with cookies that have been
matched against the document URL.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Previously we labeled redirects as normal FrameLoader::Type::Navigation,
now we introduce a new FrameLoader::Type::Redirect and label redirects
with it. This will allow us to handle redirects in the browser
differently (such as for overwritting the latest history entry when a
redirect happens) :^)
WebDriver currently uses the WebContent::ConnectionFromClient IPC class
directly for these features. To support headless-browser, WebDriver will
instead need to rely on PageClient to provide these.
Currently, all handling of pending dialogs occurs in PageHost. In order
to re-use this functionality to run WebDriver in a headless move, move
it to Page.
The way in which dialogs should be handled is configurable by the driver
capabilities object, which we don't support yet. So this implements just
the default mode to dismiss the dialog and return an error if there is
one open.
In the OOPWV, this means we need to refer to the dialog after it has
been open, so we now hold a pointer to whatever dialog is open.
Currently, the WebContent process is completely blocked while waiting
for a response to a dialog request. This patch allows the IPC event loop
to continue executing while only blocking the HTML event loop.
This will allow other processes like WebDriver to continue to operate on
the WebContent process while a dialog is open.
This just sets up the infrastructure for the WebContent process to house
WebDriver IPCs, and adds an IPC for WebContent to create the WebDriver
connection. The WebDriverConnection class inside WebContent ultimately
will contain most of what is currently in WebDriver::Session (so the
copyright attributions are copied here as well).
The socket created by WebDriver is currently /tmp/browser_webdriver
(formatted with some IDs). This will be moved to the /tmp/webdriver
folder, as WebDriver will create multiple sockets to communicate with
both Browser and WebContent as the IPCs are iteratively moved to
WebContent. That path is unveiled here, though it is unused as of this
commit.
To achieve this goal:
- The Browser unveils "/tmp/portal/filesystemaccess"
- Pass the page through LoadRequest => ResourceLoader
- ResourceLoader requests a file to the FileSystemAccessServer via IPC
- OutOfProcessWebView handles it and sends a file descriptor back to
the Page.
Some content cause a lot of paint invalidations (e.g someone drawing to
a <canvas> repeatedly) and we don't need to spam the client about this.
Instead, accumulate a dirty rect, and send it once per event loop step.
This is in preparation for implementing JS scrolling functions, which
specify both x and y scrolling deltas. The visible behavior has not
changed.
Also, moved the "mouse wheel delta * 20" calculation to the
`EventHandler` since the JS calls will want to work directly in pixels.
This allows WindowServer to use multiple framebuffer devices and
compose the desktop with any arbitrary layout. Currently, it is assumed
that it is configured contiguous and non-overlapping, but this should
eventually be enforced.
To make rendering efficient, each window now also tracks on which
screens it needs to be rendered. This way we don't have to iterate all
the windows for each screen but instead use the same rendering loop and
then only render to the screen (or screens) that the window actually
uses.

To protect the main Browser process against nefarious cookies, parse the
cookies out-of-process and then send the parsed result over IPC to the
main process. This way, if the cookie parser blows up, only that tab
will be affected.
To implement the HttpOnly attribute, the CookieJar needs to know where a
request originated from. Namely, it needs to distinguish between HTTP /
non-HTTP (i.e. JavaScript) requests. When the HttpOnly attribute is set,
requests from JavaScript are to be blocked.
