Hello all,

There may be a reasonable cause for this (i.e. it is likely to be my fault) - but it is consistent across two different machines I have tried it on. With Python 2.5b2 (from the msi at Python.org), running on Windows XP Pro SP2, os.utime and os.chmod fail with WindowsError. The same code runs fine on Python 2.3 and Python 2.4. [err] shutil.copytree(thisentry, targetdir) [err] File "C:\Python25\lib\shutil.py", line 130, in copytree [err] copystat(src, dst) [err] File "C:\Python25\lib\shutil.py", line 67, in copystat [err] os.utime(dst, (st.statime, st.stmtime)) [err] WindowsError: [Error 13] Access is denied: 'lib\Pmw' [err] The script uses shutil.copytree to copy a directory (using relative paths). IMO this is a bug in Python 2.5, on Windows. The problem is that the call to 'copystat(src, dst)' was added to the shutil.copytree function, in svn r38363 probably. It will fail always on Windows, since os.utime does not work on directories (as the docs correctly explain). I guess that a patch similar to this one should fix it: Index: shutil.py =================================================================== --- shutil.py (Revision 50710) +++ shutil.py (Arbeitskopie) @@ -127,7 +127,12 @@ # continue with other files except Error, err: errors.extend(err.args[0]) - copystat(src, dst) + try: + copystat(src, dst) + except WindowsError: + pass + except OSError, err: + errors.extend(err.args[0]) if errors: raise Error, errors But you should report this to the bug tracker. Ok, thanks.
