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.
The idea with the UI here is that it will serve as a generic component
for all site settings, such as autoplay, notifications, etc. When the
site settings dialog is opened, it is filled with the requested setting
data, and messages sent to the browser process are based on the setting.
This patch only implements the UI and persisted settings. It does not
apply autoplay changes to the WebContent process.
When we build internal pages (e.g. about:settings), there is currently
quite a lot of boilerplate needed to communicate between the browser and
the page. This includes creating IDL for the page and the IPC for every
message sent between the processes.
These internal pages are also special in that they have privileged
access to and control over the browser process.
The framework introduced here serves to ease the setup of new internal
pages and to reduce the access that WebContent processes have to the
browser process. WebUI pages can send requests to the browser process
via a `ladybird.sendMessage` API. Responses from the browser are passed
through a WebUIMessage event. So, for example, an internal page may:
ladybird.sendMessage("getDataFor", { id: 123 });
document.addEventListener("WebUIMessage", event => {
if (event.name === "gotData") {
console.assert(event.data.id === 123);
}
});
To handle these messages, we set up a new IPC connection between the
browser and WebContent processes. This connection is torn down when
the user navigates away from the internal page.
With search enabled:
- For a single word that does not look like a url: search (a
reported bug).
- If no suffix or a suffix that is not recognized: search.
In general:
- Respect the user's choice if they specified a scheme.
- Respect localhost and registered TLDs.
- As before, add file:// to filesystem files that exist.
The upcoming generated types will match those for pseudo-classes: A
PseudoElementSelector type, that then holds a PseudoElement enum
defining what it is. That enum will be at the top level in the Web::CSS
namespace.
In order to keep the diffs clearer, this commit renames and moves the
types, and then a following one will replace the handwritten enum with
a generated one.
This adds a basic settings page to manage persistent Ladybird settings.
As a first pass, this exposes settings for the new tab page URL and the
default search engine.
The way the search engine option works is that once search is enabled,
the user must choose their default search engine; we do not apply any
default automatically. Search remains disabled until this is done.
There are a couple of improvements that we should make here:
* Settings changes are not broadcasted to all open about:settings pages.
So if two instances are open, and the user changes the search engine
in one instance, the other instance will have a stale UI.
* Adding an IPC per setting is going to get annoying. It would be nice
if we can come up with a smaller set of IPCs to send only the relevant
changed settings.
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).
It really doesn't make sense for GitHub to be the default search engine.
If some really wants this, we can eventually implement setting custom
search engine URLs.
The select dropdown was doing its own ad-hoc method of handling DPR. We
now handle it just like other context menus. Previously, the drop down
in the AppKit chrome was twice as large as it should be.
When we inspect a DOM node, we currently serialize many properties for
that node, including its layout, computed style, used fonts, etc. Now
that we aren't piggy-backing on the Inspector interface, we can instead
only serialize the specific information required by DevTools.
The intent is that this will replace the separate Task Manager window.
This will allow us to more easily add features such as actual process
management, better rendering of the process table, etc. Included in this
page is the ability to sort table rows.
This also lays the ground work for more internal `about` pages, such as
about:config.
JavaScript URLs run in the same document context the navigation was
started in, so they're not eligible to be moved to a new WebContent
process.
Fixes the "Login as demo user" link on https://demo.immich.app/
These commands are used for the "Edit As HTML" feature in DevTools. This
renames our existing HTML getter IPC to indicate that it is for outer
HTML. DevTools will need a separate inner HTML getter.
Since cross-site navigation is a pretty frequent task, creating a spare
process is commonplace in other browsers to reduce the overhead of
directing the target site to a new process.
We store this process on the WebView application. If it is unavailable,
we queue a task to create it later.
Site isolation is a common technique to reduce the chance that malicious
sites can access data from other sites. When the user navigates, we now
check if the target site is the same as the current site. If not, we
instruct the UI to perform the navigation in a new WebContent process.
The phrase "site" here is defined as the public suffix of the URL plus
one level. This means that navigating from "www.example.com" to
"sub.example.com" remains in the same process.
There's plenty of room for optimization around this. For example, we can
create a spare WebContent process ahead of time to hot-swap the target
site. We can also create a policy to keep the navigated-from process
around, in case the user quickly navigates back.
This has been a longstanding ergonomic issue with our IPC compiler. Non-
trivial types were previously passed by const&. So if we wanted to avoid
expensive copies, we would have to const_cast and move the data.
We now pass ownership of all transferred data to the client subclasses.
This allows us to remove const_cast from these methods, and allows us to
avoid some trivial expensive copies that we didn't bother to const_cast.
This requires a couple of amendments to the DOM node serialization.
Namely, we need to include the HTML namespace, otherwise the context
menu item to create a new node is disabled.
