[Python-Dev] OSError.errno => exception hierarchy? (original) (raw)

Apologies if this has already been discussed.

I was expecting that by now, python 3.0, the following code:

        # clean the target dir
        import errno
        try:
            shutil.rmtree(trace_output_path)
        except OSError, ex:
            if ex.errno not in [errno.ENOENT]:
                raise

Would have become something simpler, like this:

        # clean the target dir
        try:
            shutil.rmtree(trace_output_path)
        except OSErrorNoEntry:       # or maybe os.ErrorNoEntry
            pass

Apparently no one has bothered yet to turn OSError + errno into a hierarchy of OSError subclasses, as it should. What's the problem, no will to do it, or no manpower?
