Hi Pete, that's another story. As you remember, in December we came to an end with the semantics of an root:// url when used as a destination. I modified xrdcp to make it proceed blindly, and Andy modified the xrootd protocol in order to make it work without calling Stat. When the destination is not a root:// url, in my opinion the thing to do is to mimic the behavior in the root url case, in order to have a tool which behaves in the same way with both kinds of destination. But that behavior is a little different from the one of cp if i remember. What i'd do is to check if the two behaviors are the same, and, if not, to correct the one in the non-root case. And then write something about it in the readme. What do you think? Fabrizio Peter Elmer wrote: > Hi Fabrizio, > > Ok, I'll give it a test in a bit. Did you track down the other problem?
