Previously, 'now' was set to the time `requestAnimationFrame()` was
called, and the EventLoop's 'now' was ignored. This was a little odd and
meant the time was always in the past.
By replacing the `page_did_request_scroll_to()` calls with a request
to perform scrolling in the corresponding navigable, we ensure that
the scrolling of iframes will scroll within them instead of triggering
scroll of top level document.
We have two known PlatformObjects that need to implement some of the
behavior of LegacyPlatformObjects to date: Window, and HTMLFormElement.
To make this not require double (or virtual) inheritance of
PlatformObject, move the behavior of LegacyPlatformObject into
PlatformObject. The selection of LegacyPlatformObject behavior is done
with a new bitfield of feature flags instead of a dozen virtual
functions that return bool. This change simplifies every class involved
in the diff with the notable exception of Window, which now needs some
ugly const casts to implement named property access.
Ultimately, this API should probably be replaced with something that
updates a cache on relevant DOM mutations instead of regenerating
the list of property names again and again.
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
Use a LocalSocket to represent the connection between two message ports.
The concept of the port message queue is still missing, however. When
that concept is implemented, the "steps" in step 7 of the message port
transfer steps will need to send the serialized data over the connected
socketpair and run in the event loop of the process that holds onto the
other side of the message port. Doing this should allow centralizing the
behavior of postMessage for Window, MessagePorts and Workers.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:

This is an internal object that must be explicitly enabled by the chrome
before it is added to the Window. The Inspector object will be used by a
special WebView that will replace all chrome-specific inspector windows.
The IDL defines methods that this WebView will need to inform the chrome
of various events, such as the user clicking a DOM node.
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
The main issues are using Structured{Serialize,Deserailize} instead of
Structured{Serialize,Deserialize}WithTransfer and the temporary
execution context usage for StructuredDeserialize.
Allows Discord to load once again, as it uses a postMessage scheduler
to render components, including the main App component. The callback
checked the (previously) non-existent source attribute of the
MessageEvent and returned if it was not the main window.
Fixes the Twitch cookie consent banner saying "failed integrity check"
for unknown reasons, but presumably related to the source and origin
attributes.
These allow accessing embeds, forms, images and objects with a given
name attribute, and any element with a given id attribute, as top level
properties on the global object.
It also allows accessing NavigableContainers by target name as top level
properties on the global object.
The current implementation feels very expensive. It's likely that
these values will need smarter caching in the future.
And implement WindowProperties, the "named properties object" for Window
according to the spec.
This involves moving an AO out of LegacyPlatformObject and into a common
place that the WindowProperties class can access.
This doesn't implement the AOs on Window that actually name lookup for
the unenumerable named properties on the window yet, just the
scaffolding.
In general it is not safe to convert any arbitrary floating-point value
to CSSPixels. CSSPixels has a resolution of 0.015625, which for small
values (e.g. scale factors between 0 and 1), can produce bad results
if converted to CSSPixels then scaled back up. In the worst case values
can underflow to zero and produce incorrect results.
