[issue10016] shutil.copyfile -- allow sparse copying

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

The use of fdst.truncate() is indeed wrong, since truncate() in 3.x is defined as truncating up to the current file position (which has been moved forward by the latest seek()).
