R. David Murray added the comment: The change covered by the patch (which patch rejected as garbage, by the way, I have no idea why) has already been applied by Serhiy Storchaka, apparently as a blanked change of 'empty string' to 'empty bytes object'. There are several other places in the asynchat doc page that mention string. I suspect that none of them is correct, but I haven't read through the page to be sure. ---------- nosy: +r.david.murray _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue4744> _______________________________________
