Defining it as a direct property causes it to have no getter/setter
function, which causes an empty Optional crash when attempting to
access such getter on a cross-origin iframe.
Fixes amazon.com crashing on this particular crash.
This includes:
- Moving it from Bindings/ to HTML/
- Renaming it from LocationObject to Location
- Removing the manual definitions of the constructor and prototype
- Removing special handling of the Location interface from the bindings
generator
- Converting the JS_DEFINE_NATIVE_FUNCTIONs to regular functions
returning DeprecatedString instead of PrimitiveString
- Adding missing (no-op) setters for the various attributes, which are
expected to exist by the bindings generator
DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
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 :^)
This implementation only works for cloning Numbers, and does not try to
do all the spec steps for structured serialize and deserialize.

This implementation is some-what complete, with the most common missing
/broken feature being opening pages in new tabs using the "_blank"
target.
This is currently broken due to 2 reasons:
- We currently always claim the Window does not have transient
activation, as we do not track the transient activation timestamp
yet. This means that all such window.open calls are detected as
pop-ups, and as such they are blocked. This can be easily bypassed
by unchecking the 'Block Pop-ups' checkbox in the debug menu.
- There is currently no mechanism for the WebContent process to
request a new tab to be created by the Browser process, and as
such the call to BrowsingContext::choose_a_browsing_context does not
actually open another tab.
These functions were previously ad-hoc and returned the active
document's window. They now correctly teturn the browsing context's
WindowProxy instead.
Get rid of the bespoke NavigatorObject class and use the modern IDL
strategies for creating platform objects to re-implement Navigator and
its associcated mixin interfaces. While we're here, implement it in a
way that brings WorkerNavigator up to spec :^)
This Intrinsics object hangs off of a new HostDefined struct that takes
the place of EnvironmentSettingsObject as the true [[HostDefined]] slot
on JS::Realm objects created by LibWeb.
This gets the intrinsics off of the GlobalObject, Window, similar to the
previous refactor of LibJS to move the intrinsics into the Realm's
[[Intrinics]] internal slot.
A side effect of this change is that we cannot fully initialize a Window
object until the [[HostDefined]] slot has been installed into the realm,
which happens with the creation of the WindowEnvironmentSettingsObject.
As such, any Window usage that has not been funned through a WindowESO
will not have any cached Web prototyped or constructors, and will not
have Window APIs available to javascript code. Currently this seems
limited to usage of Window in the CSS parser, but a subsequent commit
will clean those up to take Realm as well. However, this commit compiles
so let's cut it off here :^).
Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
These are from the HTML spec and therefore belong in the HTML/ directory
in LibWeb. Bindings/ has become a bit of a dumping ground, so this is a
first step towards cleaning that up.
Instead of using Core::EventLoop and Core::Timer directly, LibWeb now
goes through a Web::Platform abstraction layer instead.
This will allow us to plug in Qt's event loop (and QTimer) over in
Ladybird, to avoid having to deal with multiple event loops.
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.
There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.
This patch moves the following things to being GC-allocated:
- Bindings::CallbackType
- HTML::EventHandler
- DOM::IDLEventListener
- DOM::DOMEventListener
- DOM::NodeFilter
Note that we only use PlatformObject for things that might be exposed
to web content. Anything that is only used internally inherits directly
from JS::Cell instead, making them a bit more lightweight.
Similar to create() in LibJS, wrap() et al. are on a low enough level to
warrant passing a Realm directly instead of relying on the current realm
from the VM, as a wrapper may need to be allocated while no JS is being
executed.
Previously we forwarded all event handler attributes to Window from
these two elements, however, we are only supposed to forward blur,
error, focus, load, resize and scroll.
Previously requestAnimationFrame() callbacks were registered with a
static global RequestAnimationFrameDriver shared between all windows.
This led to callbacks still running after navigating away from a page
(This could be seen with the WASM GoL demo).
This commit moves the RequestAnimationFrameDriver (now
AnimationFrameCallbackDriver) to be a member of the HTML::Window
object, then uses the 'active document' parameter of
run_animation_frame_callbacks() to run only the active callbacks.
Right now the only functionality supported is getting/setting via JS
and resetting when browsing cross origin.
The HTML Specification (7.11 Browsing the web) also specifies how the
name should be restored from history entries, but we don't have those
yet.
