[issue2845] shutil.copy2() copies permission bits

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

This seems to be a documentation issue.

"""
shutil.copy2(src, dst)
Similar to copy(), but last access time and last modification time are 
copied as well. This is similar to the Unix command cp -p.
""" -- http://docs.python.org/dev/library/shutil.html#shutil.copy2

Does not mention permissions while

"""
$ pydoc shutil.copy2
shutil.copy2 = copy2(src, dst)
    Copy data and all stat info ("cp -p src dst").
"""

implies that the permissions should be copied.

Maybe the documentation should simply recite the implementation: copy2 
is copyfile follwed by copystat.
