Reviewed by Brent Fulgham.
When dropping a local file in a WKWebView or in the chrome of the embedding
application, WebKit is normally only provided with a
temporary sandbox extension to that location in the UI process by the system or
embedding application. If we later visit the same
local file URL, either by going back/forward in history, or manually entering
the file URL in the address field, we are no longer
able to create a sandbox extension to that location for the WebContent process,
since the temporary sandbox extension has been
revoked in the UI process. To address this, we can add a sandbox extension
cache in the process pool, which lets us send a
sandbox extension to the WebContent process in these cases. This requires the
SandboxExtensionHandle class to be copyable.
