samba - Nov 2017 - Server-side copy support for Mac OS clients

Is this supposed to be supported in Samba 4.7.1? Server side copies work
fine using a Windows client. From mac OS 10.13.2, there's a full
transfer of a file being copied.

Yes, it's supported, and should work fine with (and IIUC also without)
the vfs_fruit module enabled. I'm not aware of the macOS client version
required, but Ralph (cc'ed) might be.

Cheers, David

there's a special macOS copyfile extension that requests a complete
file+streams
copy in one request. It's supported by fruit but of by default:

       fruit:copyfile = yes | no
           A global option whether to enable OS X specific copychunk ioctl that
requests a
           copy of a whole file along with all attached metadata.

           WARNING: the copyfile request is blocking the client while the server
does the
           copy.

           The default is no.
