I am having trouble using the IconDatabase successfully. I was
wondering if I am either using it incorrectly or if Safari is doing
some extra work to get the correct favicon for a given site.
Here is the scenario. I am going to assume that each icon is retained
at least once so that icons are never deleted (in fact, for testing
this is exactly what I'm doing).
Load www.google.com, FrameLoaderClient::dispatchDidReceiveIcon is
called. IconDatabase::iconForPageURL returns an icon, this is
perfect. Load www.google.com/search?hl=en&q=some_query&btnG=Google
+Search, dispatchDidReceiveIcon is *not* called. If I call
iconForPageURL *before* the load is finished, I won't get an icon
unless I have already visited the site. If I call it after the load
has finished, this could potentially show the wrong icon until the
load has finished.
Here is the behavior that I want:
Load www.google.com, show the default icon until the google favicon
is loaded and dispatchDidReceiveIcon is called. Load www.google.com/
search?hl=whatever, show the google favicon unless
dispatchDidReceiveIcon is called. Load www.someothersite.com, show
the default icon until dispatchDidReceiveIcon is called. How can I
accomplish this behavior when the IconDatabase doesn't know about
pageUrls->iconUrls until *after* the load has completed?
Thanks,
Patrick
