Instead of taking the JS::Heap&. This allows us to get rid of some
calls to JS::Interpreter::global_object(). We're getting closer and
closer to multiple global objects. :^)
We still have to hand-write a function to turn an Event& into a wrapper
but this is still a hue improvement. Eventually we'll find a way to
auto-generate that function as well.
We now store the response headers in a download object on the protocol
server side and pass it to the client when finishing up a download.
Response headers are passed as an IPC::Dictionary. :^)
A MarkedValueList is basically a Vector<JS::Value> that registers with
the Heap and makes sure that the stored values don't get GC'd.
Before this change, we were unsafely keeping Vector<JS::Value> in some
places, which is out-of-reach for the live reference finding logic
since Vector puts its elements on the heap by default.
We now pass all the JavaScript tests even when running with "js -g",
which does a GC on every heap allocation.
In order to complete a relative URL, we need a Document. Fix this by
giving XMLHttpRequest a pointer to its window object. Then we can go
from the window to the document, and then we're home free. :^)
This patch adds very basic XMLHttpRequest support to LibWeb. Here's an
example that currently works:
var callback = function() { alert(this.responseText); }
var xhr = new XMLHttpRequest();
xhr.addEventListener("load", callback);
xhr.open("GET", "http://serenityos.org/~kling/test/example.txt");
xhr.send();
There are many limitations and bugs, but it's pretty dang awesome that
we have XHR. :^)
