Instead of just the outline, fill them with some semi-transparent color.
Also add tag name, ID, classes and coordinates to the little tooltip.
Finally, use the border box instead of the context box for metrics,
same as other browsers.
I can't imagine how this happened, but it seems we've managed to
conflate the "event listener" and "EventListener" concepts from the DOM
specification in some parts of the code.
We previously had two things:
- DOM::EventListener
- DOM::EventTarget::EventListenerRegistration
DOM::EventListener was roughly the "EventListener" IDL type,
and DOM::EventTarget::EventListenerRegistration was roughly the "event
listener" concept. However, they were used interchangeably (and
incorrectly!) in many places.
After this patch, we now have:
- DOM::IDLEventListener
- DOM::DOMEventListener
DOM::IDLEventListener is the "EventListener" IDL type,
and DOM::DOMEventListener is the "event listener" concept.
This patch also updates the addEventListener() and removeEventListener()
functions to follow the spec more closely, along with the "inner invoke"
function in our EventDispatcher.
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.
Instead of making each Layout::Node compute style for itself, we now
compute it in TreeBuilder before even calling create_layout_node().
For non-element DOM nodes, we create the style and layout tree node
in TreeBuilder. This allows us to move create_layout_node() from
DOM::Node to DOM::Element.
This changes allows for nested browser contexts to be embedded in the
serialized JSON of their container element (like `iframe`) and enables
their inspection in the DOM Inspector.
Use a simple heuristic to exclude uninteresting whitespace and
de-clutter the inspector's DOM tree.
Uninteresting whitespace is currently one of these:
- Non-rendered whitespace-only text nodes
- Rendered whitespace-only text nodes between block-level elements
Since style update is driven by Document, moving a node with dirty style
from one document to another means that we have to schedule a style
update in the new document.
Instead of doing layout synchronously whenever something changes,
we now use a basic event loop timer to defer and coalesce relayouts.
If you did something that requires a relayout of the page, make sure
to call Document::set_needs_layout() and it will get coalesced with all
the other layout updates.
There's lots of room for improvement here, but this already makes many
web pages significantly snappier. :^)
Also, note that this exposes a number of layout bugs where we have been
relying on multiple relayouts to calculate the correct dimensions for
things. Now that we only do a single layout in many cases, these kind of
problems are much more noticeable. That should also make them easier to
figure out and fix. :^)
The previous implementation was about a half implementation and was
tied to Element::innerHTML. This separates it and puts it into
HTMLDocumentParser, as this is in the parsing section of the spec.
This provides a near finished HTML fragment serialisation algorithm,
bar namespaces in attributes and the `is` value.
The current implementation felt a bit ad-hoc and notably allowed
textContent to operate on all node types. It also only returned the
child text content of the Node instead of the descendant text content.
We maintain a directory of ID -> Node. Nodes add themselves to this
directory when they are created, receiving a random ID. When a Node is
destroyed, it removes itself from this directory. Anyone can request a
Node from the directory by its ID using `Node::from_id()`.
We reserve the `0` ID to mean "none".
These IDs allow different processes to communicate about a given Node
over IPC, for example the DOM Inspector.
This will be used in HTMLTemplateElement later to clone template
contents.
This makes the clone functions non-const in the process, as the cloning
steps can have side effects.
It was directly creating a new Element object instead of creating the
appropriate element.
For example, document.body.cloneNode(true) would return an Element
instead of an HTMLBodyElement.
This method builds a JSON object representing the full state of the
DOM tree.
The JSON that is built will be used for building the DOM Inspector
widget for the OutOfProcessWebView.
The WebIDL spec specifies a few "simple" exception types in addition to
the DOMException type, let's support all of those.
This allows functions returning ExceptionOr<T> to throw regular
javascript exceptions (as limited by the webidl spec) by returning a
`DOM::SimpleException { DOM::SimpleExceptionType::T, "error message" }`
which is pretty damn cool :^)
