Hello,

I am working on the subprocess.Popen module for Python 2.7 and am now moving my changes over to Python 3.1 however I am having trouble with the whole byte situation and I can't quite seem to understand how to go back and forth between bytes and strings. I am also looking for the Python 3k equivalent for the Python 2.X built-in buffer class.

Look at the "memoryview" type as a replacement for buffer. io.Buffered* is not the same.

FYI, it is used slightly differently. Rather than x = buffer(y, offset), you use x = memoryview(y)[offset:].

...

One version of the file with my modifications can be found here  < http://code.google.com/p/subprocdev/source/browse/subprocess.py?spec=svn5b570f8cbfcaae859091eb01b21b183aa5221af9&r=5b570f8cbfcaae859091eb01b21b183aa5221af9

...

. Lines 1 - 15 are me attempting to get around certain changes between Python 3.0 and Python 2.7. Further down on line 916, we have the function "send" and "recv" in which I am having the most trouble with bytes and strings.

You translate between bytes and strings through encoding and decoding. Have you read https://secure.wikimedia.org/wikipedia/en/wiki/Unicode?

Any help is appreciated. Feel free to comment on my blog http://subdev.blogspot.com/ or reply to the last.

Have you talked with your mentor about these things?
