示例1: assertConnectedSubrameCountIsConsistent
static unsigned assertConnectedSubrameCountIsConsistent(ContainerNode& node)
{
unsigned count = 0;
if (is<Element>(node)) {
if (is<HTMLFrameOwnerElement>(node) && downcast<HTMLFrameOwnerElement>(node).contentFrame())
++count;
if (ShadowRoot* root = downcast<Element>(node).shadowRoot())
count += assertConnectedSubrameCountIsConsistent(*root);
}
for (auto& child : childrenOfType<Element>(node))
count += assertConnectedSubrameCountIsConsistent(child);
// If we undercount there's possibly a security bug since we'd leave frames
// in subtrees outside the document.
ASSERT(node.connectedSubframeCount() >= count);
// If we overcount it's safe, but not optimal because it means we'll traverse
// through the document in disconnectSubframes looking for frames that have
// already been disconnected.
ASSERT(node.connectedSubframeCount() == count);
return count;
}示例2: disconnectSubframes
void disconnectSubframes(ContainerNode& root, SubframeDisconnectPolicy policy)
{
#ifndef NDEBUG
assertConnectedSubrameCountIsConsistent(root);
#endif
ASSERT(root.connectedSubframeCount());
Vector<Ref<HTMLFrameOwnerElement>> frameOwners;
if (policy == RootAndDescendants) {
if (is<HTMLFrameOwnerElement>(root))
frameOwners.append(downcast<HTMLFrameOwnerElement>(root));
}
collectFrameOwners(frameOwners, root);
// Must disable frame loading in the subtree so an unload handler cannot
// insert more frames and create loaded frames in detached subtrees.
SubframeLoadingDisabler disabler(root);
bool isFirst = true;
for (auto& owner : frameOwners) {
// Don't need to traverse up the tree for the first owner since no
// script could have moved it.
if (isFirst || root.containsIncludingShadowDOM(&owner.get()))
owner.get().disconnectContentFrame();
isFirst = false;
}
