Issue2894

When urllib2-POSTing data > 64k the request times out and returns:

httplib.BadStatusLine: ''

<= 64k works fine.

Tested in newest (2.7.2 and 2.7.2b3, 2.7.2b2).

To test modify line 5 to make the request bigger than 64k

Sending mails with smtplib.py seems to suffer the same issue.
When sending an message > 64k (e.g. adding an attachment) the system stops for 5 minutes and then reports:
smtplib.SMTPServerDisconnected: Server not connected

I managed to create a workaround:
removing sock.sendall in smtplib.py and replacing it by sending out 0xffff-sized chunks.
Implementation is inefficient but works...

...workaround is only for sending mails of course!

Inspired by my own workaround ;-)
Found the issue in _socket.py:

-    sendall = send   # FIXME see note above!

replace with:

    def sendall(self, data, flags=0):
        chunk_size = 8192
        length = len(data)
        data_view = memoryview(data)
        idx = 0
        while idx < length:
            bytes_sent = self.send(data_view[idx:idx + chunk_size], flags=flags)
            idx += bytes_sent

then all is working.
