This is used by window.close() programmatically, but of course the user
can also decide to close a top-level browsing context at any time by
closing the tab.
We now implement the browsing context's "set active document" algorithm
from the spec, as well as the "discard" algorithm for browsing contexts
and documents.
We can now "update the visibility state", which also causes
`visibilitychange` events to fire on the document.
This still needs GUI integration work at the BrowsingContext level.
We're still missing the lazy loading attribute handling, and once we hit
the navigation step, we fall back to totally ad-hoc behavior instead of
going all the way with a Fetch Request.
We had glossed over a condition in the spec that said we should only run
the nested context creation steps when the iframe's own containing
document has a browsing context.
This remained undetected for a long time as HeaderCheck is disabled by
default. This commit makes the following file compile again:
// file: compile_me.cpp
#include <LibWeb/HTML/CrossOrigin/CrossOriginOpenerPolicy.h>
// That's it, this was enough to cause a compilation error.
Likewise for most other files touched by this commit.
Instead of asking Gfx::FontDatabase for the "default font" and the
"default fixed-width font", we now proxy those requests out via
the Platform::FontPlugin. This will allow Ladybird to use other default
fonts as fallback.
This replaces the previous Web::ImageDecoding::Decoder interface.
While we're doing this, also move the SerenityOS implementation of this
interface from LibWebView to WebContent. That means we no longer have to
link with LibImageDecoderClient in applications that use a web view.
The document.domain setter is currently stubbed as that is a doozy to
implement, given how much restrictions there are in place to try and
prevent use of it and potential multi-process implications.
This was the only thing preventing us from being able to start
displaying ads delivered via Google Syndication.
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.
We were constantly measuring and re-measuring the "alt" attribute text
of ImageBox layout nodes, even when the alt text didn't change. By
caching this, we avoid a *lot* of repeated text measurement work.
Instead, use the window object from the context element. This fixes an
issue where activating event handlers during fragment parsing would try
to set up callbacks using the internal window object's ESO.
This caused a verify_cast crash on Google Maps, since the internal realm
doesn't have an associated ESO. Perhaps it should, but in this specific
case, it makes more sense for fragment parsing to fully adopt the
context provided.
This allows the garbage collector to keep HTML::Script objects alive and
fixes a bug where a HTMLScriptElement could get GC'd while its code was
executing.
Workers don't have a document, so we can't ask them if scripting is
enabled or not. This is not the right long-term fix, but it fixes an
assertion when trying to query the missing responsible document of a
web worker.
This is *not* according to spec, however we currently store prototypes
and constructors on Window, so the only way for objects in a worker
context to become fully formed is to make a Window.
Long-term we should clean this up and remove the worker window object,
but for now it allows workers to exist without asserting.
wrap() is now basically a no-op so we should stop using it everywhere
and eventually remove it. This patch removes uses of wrap() in
non-generated code.
