I think that we decided for now that we were going to allow importing
everything, since we don't disallow importing the sync credential via browser
import. We should file a bug for this to make sure that it doesn't get lost
though.

[Garrett Casto, 2015/06/23 23:42:35]

Why aren't you just returning password_list_.Pass()?

[xunlu, 2015/06/25 17:12:15]

If I just return password_list_.Pass(), I will need to call
UpdatePasswordLists() in PasswordManagerHandler to repopulate password_list_.
But I think it's better to just wrap this call in PasswordManagerPresenter.

[Garrett Casto, 2015/06/26 21:13:48]

Got it. What I was actually thinking is that this should have been
password_list_.get(), but that doesn't work either because you pass the data on
to the FILE thread afterwards.

Both for clarity and to save ourselves the work of actually reloading here, I
would probably just do an explicit copy here. There is no trivial way to perform
a deep copy of a ScopedVector, so I think that you loop through the vector and
explicitly copy every element.

Done.
