I read that Python 2.6 is planned to Wednesday. One bug is is still open and important for me: Python 2.6/3.0 are unable to use filename as byte strings. http://bugs.python.org/issue3187

Ooops, as amaury noticed, the problem is specific to Python 3.0. My example works correctly with Python 2.6:

$ find . ./a?b ./dir?name ./dir?name/file

$ ~/prog/python-trunk/python Python 2.6rc2+ (trunk:66627M, Sep 26 2008, 19:03:31) >>> import os, shutil >>> os.listdir('.') ['a\xffb', 'dir\xffname'] >>> open(os.listdir('.')[0]).close() >>> os.unlink(os.listdir('.')[0]) >>> os.listdir('.') ['dir\xffname'] >>> shutil.rmtree(os.listdir('.')[0])

Same test with Python 3.0:

$ pwd /tmp/test

$ find . ./a?b ./dir?name ./dir?name/file

$ ~/prog/py3k/python Python 3.0rc1+ (py3k:66627M, Sep 26 2008, 18:10:03) >>> import os, shutil >>> os.listdir('.') [b'a\xffb', b'dir\xffname'] >>> open(os.listdir('.')[0]).close() Traceback (most recent call last): File "", line 1, in NOT FOUNT >>> os.unlink(os.listdir('.')[0]) >>> os.listdir('.') [b'dir\xffname'] >>> shutil.rmtree(os.listdir('.')[0]) Traceback (most recent call last): File "", line 1, in NOT FOUNT

Results:

Another example to test chdir()/getcwd():

$ pwd /tmp/test

$ ~/prog/py3k/python Python 3.0rc1+ (py3k:66627M, Sep 26 2008, 18:10:03) >>> import os, shutil >>> os.getcwd() '/tmp/test' >>> os.chdir(b'/tmp/test/dir\xffname') >>> os.getcwd() Traceback (most recent call last): File "", line 1, in NOT FOUNT
