I did
$ ln -s ~/mapping/aiyongxian/aiyongxian.kml /tmp/
Then in emacs I did
C ;; dired-do-copy
Overwrite ‘/tmp/aiyongxian.kml’? [Type yn!q or C-h] y
Copy: ‘/home/jidanni/mapping/aiyongxian/aiyongxian.kml’ to ‘/tmp/aiyongxian.kml’ failed:
(file-error Input and output files are the same Success /home/jidanni/mapping/aiyongxian/aiyongxian.kml /tmp/aiyongxian.kml)
OK, but why the word "Success"?!

Because that's not really a "failure": the file was already there.

OK, but, the shell says 1, not 0:
$ ln -s ~/mln -s ~/mapping/aiyongxian/aiyongxian.kml /tmp/
$ cp ~/mapping/aiyongxian/aiyongxian.kml /tmp/; echo $?
cp: '/home/jidanni/mapping/aiyongxian/aiyongxian.kml' and '/tmp/aiyongxian.kml' are the same file
1
Also
>> (file-error Input and output files are the same Success /home/jidanni/mapping/aiyongxian/aiyongxian.kml /tmp/aiyongxian.kml)
should be
>> (file-error Input and output files are the same. Success. /home/jidanni/mapping/aiyongxian/aiyongxian.kml /tmp/aiyongxian.kml)
But that doesn't make sense either.
Obviously the word Success has been stuck in the middle, and should be
moved to the front or back. And in fact changed to Failure.

So does Emacs: that's why you get the error message. The "Success"
part comes from the value of errno.

I see. Success means failure.
Or maybe failure means success.
OK. Got it.

Also "failure is not an option".

I think we should thank POSIX for any confusion that can come from this.
So should this be closed as notabug?

Yes, I think so.
