[Python-Dev] os.utime and os.chmod failures (etc) Python 2.5b2
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.st_atime, st.st_mtime)) [err] WindowsError: [Error 13] Access is denied: 'lib\\Pmw' [err] The script uses ``shutil.copytree`` to copy a directory (using relative paths). The source code snippet is : if os.path.isdir(targetdir): shutil.rmtree(targetdir) shutil.copytree(thisentry, targetdir) The code in shutil.py is : def copystat(src, dst): Copy all stat info (mode bits, atime and mtime) from src to dst st = os.stat(src) mode = stat.S_IMODE(st.st_mode) if hasattr(os, 'utime'): os.utime(dst, (st.st_atime, st.st_mtime)) if hasattr(os, 'chmod'): os.chmod(dst, mode) Additionally, after running a couple of times I get core dumps when trying to run the interactive interpreter. Oddly IDLE and other programs still run. However this is after installing py2exe, wxPython and pywin32 (all of which have Python 2.5 builds), so there is possibly some weird interaction. My install directory has the following three dlls in it : MSVCIRT.dll MSVCP60.dll MSVCRT.dll It has none of the msvc7 dlls that I would expect. I'm now at work and so don't have time to experiment, but tonight I will try uninstalling all my Python 2.5 stuff and re-installing just 2.5b2. I will see what dlls are present, run the interpreter a few times, and test a simple script with shutil.copytree.

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.
