Currently in OBEXD, only OPP put has authorization and file progress

add a new method namely GetProperties in transfer, which returns the

We try to avoid such extra round-trips in our D-Bus APIs. If such a
feature is really needed the essential context information should be
provided as parameters to the "authorize" call.
Im not so sure authorize here is really useful since FTP requires
connection authorization anyway, we can create transfers if the
purpose is to log them.
Thanks for your reply.
Even if FTP has connection authorization I think it is better to ask
file authorization for put/get/delete. This gives more flexibility to
application. It is up to application to decide whether to ask end user
or simply accept. Also in put case if a file with same filename is already
there, then this approach will be useful for application to handle that.
I think you may be confusing use cases.
If you are an FTP server, you are giving authorized remote users blanket
authority to read, write or browse, or some combination, your exposed
FTP file system. I suppose you could require additional
operation-by-operation request/confirm, but that would quickly make the
system very clumsy. It's not the usage model that FTP was designed for.
That is why we have the OPP profile, which is specifically for single
object sharing, and that has that kind of request/confirm model.
