shutil.copy Problem

[David Nicolson]

Hi John,

That was an excellent idea and it was the cause problem. Whether this  
is a bug in shutil I'm not sure.

Here is the traceback, Python 2.4.3 on Windows XP:

> C:\Documents and Settings\Güstav>C:\python243\python Z:\sh.py
> Copying  u'C:\\Documents and Settings\\G\xfcstav\\My Documents\\My  
> Music\\iTunes
> \\iTunes Music Library.xml' ...
> Traceback (most recent call last):
>   File "Z:\sh.py", line 12, in ?
>     shutil.copy(xmlfile,"C:iTunes Music Library.xml")
>   File "C:\python243\lib\shutil.py", line 81, in copy
>     copyfile(src, dst)
>   File "C:\python243\lib\shutil.py", line 41, in copyfile
>     if _samefile(src, dst):
>   File "C:\python243\lib\shutil.py", line 36, in _samefile
>     return (os.path.normcase(os.path.abspath(src)) ==
> UnicodeDecodeError: 'ascii' codec can't decode byte 0xfc in  
> position 27: ordinal
> not in range(128)

Here is the code:

> import _winreg
> import os
> import shutil
>
> reg = _winreg.ConnectRegistry(None, _winreg.HKEY_CURRENT_USER)
> key = _winreg.OpenKey(reg, r"Software\Microsoft\Windows 
> \CurrentVersion\Explorer\Shell Folders", 0, _winreg.KEY_READ)
> mymusic = _winreg.QueryValueEx(key, "My Music")[0]
>
> xmlfile = os.path.join(os.path.join(mymusic,"iTunes"),"iTunes Music  
> Library.xml")
> print "Copying ",repr(xmlfile),"..."
>
> shutil.copy(xmlfile,"C:\iTunes Music Library.xml")

The shutil line needed to be changed to this to be successful:

> shutil.copy(xmlfile.encode("windows-1252"),"C:\iTunes Music  
> Library.xml"


Regards,
David
