STINNER Victor <[EMAIL PROTECTED]> added the comment: I wrote a Filename class. I tries different methods: * no parent class "class Filename: ..." -> I don't know how to make bytes(filename) works!? But it's the best option to avoid strange bugs (mix bytes/str, remember Python 2.x...) * str parent class "class Filename(str): ..." -> doesn't work because os functions uses the fake unicode filename before testing the bytes (real) filename * bytes parent class "class Filename(bytes): ..." -> that's the current implementation
The idea is to encode str -> bytes (and not bytes -> str because we want to avoid problems with such conversions). So I reimplemented most bytes methods: __addr__, __raddr__, __contains__, startswith, endswith and index. index method has no start/end arguments since the behaviour would be different than a real unicode string :-/ I added an example of fixed os.listdir(): create Filename() object if we get bytes. Should we always create Filename objects? I don't think so.
