Create entire frame tree in iframe processes
https://bugs.webkit.org/show_bug.cgi?id=254126
Reviewed by Chris Dumez.
This makes it so that in a subframe process, we make the entire frame tree with
a RemoteFrame as the main frame.
The next step will be to broadcast frame tree changes to all processes when an
iframe is made in one process.
In order to get the pixels from the iframe to still draw to the screen, we had
to introduce the concept of
root frames, which are the topmost LocalFrames in a particular process, and
those are the frames that have a root
layer that is sent to the UI process in a RemoteLayerTreeTransaction. In
places where we used to tell the main
frame to draw, we now need to iterate all the root layers and tell each of them
to draw. We currently only have
unit tests that have one root layer per process, but this is a step towards
having the ability to have multiple,
such as if a.com has two iframes, each of which is showing b.com.
Instead of using the DrawingArea::UpdateGeometry message to update the size of
iframes, we make a new message
WebPage::UpdateFrameSize for that purpose that does many of the same things,
importantly calling FrameView::resize
to make iframes draw their content into Widgets that are the right size to
composite into another process's content.
I remove a hack I introduced for WebFrameProxy::didFinishLoad to ignore
about:blank when considering whether to send
WebFrame::DidFinishLoadInAnotherProcess. The hack is no longer necessary.
The ProvisionalFrameProxy constructor sent WebPage::LoadRequest messages twice.
That was a mistake that wasn't making
any tests fail yet, but we only need to send it once.
WebKitTestRunner needed a null check to not crash in the test
http/tests/site-isolation/basic-iframe.html because
WKBundlePageGetMainFrame returns a WebFrame wrapping a RemoteFrame. It's fine
to just early return because we aren't
getting render tree output in any site isolation tests yet, but we will likely
need to revisit that change when we do.
