This reduces the recompilation cascade when Document.h is modified,
cutting off the transitive path through ~30 SVG element headers.
Move the inline try_resolve_url_to() template body in
SVGGraphicsElement.h to a non-template helper in the .cpp file to
avoid needing Document.h and ShadowRoot.h in the header.
Add explicit includes to files that relied on the transitive dependency.
SVG images loaded as <img> elements must not execute scripts per spec.
Previously, SVGScriptElement::process_the_script_element() did not
check whether scripting was disabled, so script processing was
triggered via the children_changed() callback during XML parsing,
causing a nested event loop spin.
Fix this by:
- Disabling scripting on the SVG image's Page
- Passing XMLScriptingSupport::Disabled to the XML document builder
- Checking is_scripting_disabled() in SVGScriptElement before
processing any script element
- Logging a diagnostic when SVG XML parsing fails (previously the
parse result was silently discarded)
An upcoming commit will migrate the contents of Headers.h/cpp to LibHTTP
for use outside of LibWeb. These CORS and MIME helpers depend on other
LibWeb facilities, however, so they cannot be moved.
Before this change, we were going through the chain of base classes for
each IDL interface object and having them set the prototype to their
prototype.
Instead of doing that, reorder things so that we set the right prototype
immediately in Foo::initialize(), and then don't bother in all the base
class overrides.
This knocks off a ~1% profile item on Speedometer 3.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
