Note: This overloads the naming of some of the existing infrastructure,
but the signatures etc are sufficient to disambiguate. The other infrastructure
goes away in a subsequent patch.
Note: We tag sandbox expandos with their global to make sure that the expandos
are never shared between sandboxes. A consequence of this scheme is that an
expando from a sandbox to an object will _always_ result in a GC edge back to
the sandbox, meaning that the sandbox is always kept alive for the lifetime of
the expando target. This could happen before, but only if a non-primitive expando
was placed (since the value of the expando would live in the consumer's
compartment). We could avoid this edge by using a reference-counted Identity()
object instead, but I suspect it's not worth worrying about.
When Firefox downloads an update, it previously kept the update around to apply
it on the next restart. This patch changes this so that the updater program
is launched in the background as soon as the update has finished downloading
in order to stage the updated version of the application by copying the
existing installation directory to a temporary location and applying the update
on top of it, and replace the existing installation directory with the staged
directory on the next restart.
Because the replacing step is typically very fast, this patch eliminates the
wait for the update to be applied on restart, making it unnecessary to show a
progress dialog when restarting.
