Using your latest patches, I've tried
M-: (copy-directory "/ssh::/tmp/test" "/ssh::~/")
This results in a wrong target directory structure. This is, because
Tramp has no own implementation of copy-directory for the ssh method, it
falls back to the default implementation. So we have the call tree:
copy-directory
-> copy-directory-1
-> tramp-handle-copy-directory
-> copy-directory
You see, there are serious problems when a file name handler is called
from a function which shouldn't.
M-: (copy-directory-1 "/ssh::/tmp/test" "/ssh::~/")
works fine. Given this behaviour, the file name handler should be
provided for copy-directory-1, which is just a helper function ...
Maybe it has been discussed at the beginning already, but I don't catch
what is wrong with using the implementation of copy-directory-1 for
copy-directory.
Best regards, Michael.
