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 :^)
The XHR gives us a set of conditions where XHR objects must survive
garbage collection, even when there are no pointers to them on the heap.
This patch implements those conditions using the new cell
self-protection mechanism in LibJS.
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.
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.
The Fetch spec unfortunately will cause a name clash between the Request
concept and the Request JS object - both cannot live in the Web::Fetch
namespace, and WrapperGenerator generally assumes `Web::<Name>` for
things living in the `<Name>/` subdirectory, so let's instead move infra
code into its own namespace - it already sits in a (sub-)subdirectory
anyway.
This patch adds support for URLSearchParams to XHR::send() and
introduces the union type XMLHttpRequestBodyInit.
XHR::send() now has support for String and URLSearchParams.
This adds the XMLHttpRequest::open(String, String, bool, String, String)
overload.
The following FIXMEs has been implemented:
- If method is not a method, then throw a "SyntaxError" DOMException.
- If the username argument is not null, set the username given parsedURL
and username.
- If the password argument is not null, set the password given parsedURL
and password.
- Set this’s synchronous flag if async is false; otherwise unset this’s
synchronous flag.
Spec comments has also been updated.
The MIME type can come from either the Content-Type header in the
response header list, or the overridden MIME type passed into
overrideMimeType()
This is required by Google Maps, which downloads blobs encoded
in x-user-defined format.
This allows you to ignore the Content-Type returned by the server and
always parse the content as if it's the given MIME type.
This will currently be used for allowing you to override the charset
of text responses.
This isn't perfect (especially the global object situation in
activate_event_handler), but I believe it's in a much more complete
state now :^)
This fixes the issue of crashing in prepare_for_ordinary_call with the
`i < m_size` crash, as it now uses the IDL callback functions which
requires the Environment Settings Object. The environment settings
object for the callback is fetched at the time the callback is created,
for example, WrapperGenerator gets the incumbent settings object for
the callback at the time of wrapping. This allows us to remove passing
in ScriptExecutionContext into EventTarget's constructor.
With this, we can now drop ScriptExecutionContext.
