// the main RenderFrame.
// 2. The RenderFrame can be unloaded. In this case, the browser sends a
// mojom::FrameNavigationControl::UnloadFrame message for the RenderFrame
// to replace itself with a `blink::RemoteFrame`and release its associated
// resources. |lifecycle_state_| is advanced to
// LifecycleStateImpl::kRunningUnloadHandlers to track that this IPC is in
// flight.
// 3. The RenderFrame can be detached, as part of removing a subtree (due to
// navigation, unload, or DOM mutation). In this case, the browser sends
// a mojom::FrameNavigationControl::Delete message for the RenderFrame
// to detach itself and release its associated resources. If the subframe
// contains an unload handler, |lifecycle_state_| is advanced to
// LifecycleStateImpl::kRunningUnloadHandlers to track that the detach is
// in progress; otherwise, it is advanced directly to
// LifecycleStateImpl::kReadyToBeDeleted.
//
// For BackForwardCache or Prerender case:
//
// Deleting the BackForwardCache::Entry deletes immediately all the
// Render{View,Frame,FrameProxy}Host. This will destroy the main RenderFrame
// eventually as part of path #1 above:
//
// - The RenderFrameHost/RenderFrameProxyHost of the main frame are owned by
// the BackForwardCache::Entry.
// - RenderFrameHost/RenderFrameProxyHost for sub-frames are owned by their
// parent RenderFrameHost.
// - The RenderViewHost(s) are refcounted by the
// RenderFrameHost/RenderFrameProxyHost of the page. They are guaranteed not
// to be referenced by any other pages.
//
// The browser side gives the renderer a small timeout to finish processing
// unload / detach messages. When the timeout expires, the RFH will be
// removed regardless of whether or not the renderer acknowledged that it
// completed the work, to avoid indefinitely leaking browser-side state. To
// avoid leaks, ~RenderFrameHostImpl still validates that the appropriate
// cleanup IPC was sent to the renderer, by checking IsPendingDeletion().
//
// TODO(dcheng): Due to how frame detach is signalled today, there are some
// bugs in this area. In particular, subtree detach is reported from the
// bottom up, so the replicated mojom::FrameNavigationControl::Delete
// messages actually operate on a node-by-node basis rather than detaching an
// entire subtree at once...
//
// Note that this logic is fairly subtle. It needs to include all subframes
// and all speculative frames, but it should exclude case #1 (a main
// RenderFrame owned by the `blink::WebView`). It can't simply check
// |frame_tree_node_->render_manager()->speculative_frame_host()| for
// equality against |this|. The speculative frame host is unset before the
// speculative frame host is destroyed, so this condition would never be
// matched for a speculative RFH that needs to be destroyed.
//
// Note that `RenderViewHostImpl::GetMainRenderFrameHost()` can never return
// a speculative RFH. So, a speculative main frame being deleted will always
// pass this condition as well.
