Hi there,
Maybe you did not understand the proposed algorithm, no copies are
involved, just file renaiming. I was thinking more in the lines of
doing this:
IF A and B are the same THEN
- move B to a temporary file (predefined name or random name, as long
as the file does not exist)
- create a hardlink B to A
IF the hard link fails THEN
* restore the temporary file to B (rename, not copy) and complain
ELSE
* emove the temporary file and declare success
I still have to investigate if detecting files across different
filesystems is something easy or not, but the approach above should
work (although there are some race conditions)
Regards
Javier
