Hi Mathijs, Quoting [Mathijs den Burger] (Sep 30 2009):

Hi all,

The notes of ns_entry.move(saga::url target) say:

- an identical copy exists at target - the original entry is removed

The postcondition of ns_entry.remove() says:

the original entry is closed and removed

Does this imply that ns_entry.move() also closes the original ns_entry? The spec is a bit vague here...

Yes, that is indeed somewhat vague, I'll try to clarify. For now: no, the semantics of remove() is not used by mopve(), in particular the entry stays open. What basically is supposed to happen is: // prepare: // # rm -rf /tmp/t1 // # rm -rf /tmp/t2 // # ls > /tmp/t1 saga::name_space::directory d ("file://localhost/tmp/"); saga::name_space::entry e = d.open ("t1"); assert ( d.exists ("t1") ); assert ( ! d.exists ("t2") ); std::cout << e.get_url () << " : " << e.get_size () << std::endl; e.move ("t2", Overwrite); std::cout << e.get_url () << " : " << e.get_size () << std::endl; assert ( ! d.exists ("t1") ); assert ( d.exists ("t2") ); this should print file://localhost/tmp/t1 : 1234 file://localhost/tmp/t2 : 1234 and the asserts should pass. In particular, the entry 'e' stays open and is in a valid state. Does that make sense? As said, I'll try to clarify that in the spec. Cheers, Andre.
