[New-bugs-announce] [issue9177] ssl.read/write on closed socket raises AttributeError

[Cyril]

New submission from Cyril <cbay at excellency.fr>:

This:

import socket, ssl

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ssl_sock = ssl.wrap_socket(s)
ssl_sock.connect(('www.verisign.com', 443))
ssl_sock.close()
ssl_sock.read(1024)

raises:

Traceback (most recent call last):
  File "/tmp/bug.py", line 10, in <module>
    ssl_sock.read(1024)
  File "/path/to/lib/python2.7/ssl.py", line 138, in read
    return self._sslobj.read(len)
AttributeError: 'NoneType' object has no attribute 'read'


I would expect a socket.error instead, which mimics the way regular sockets behave. Indeed, this code:

import socket, ssl

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('www.verisign.com', 80))
s.close()
s.recv(1024)

raises:

Traceback (most recent call last):
  File "/tmp/bug.py", line 6, in <module>
    s.recv(1024)
  File "/path/to/lib/python2.7/socket.py", line 170, in _dummy
    raise error(EBADF, 'Bad file descriptor')
socket.error: [Errno 9] Bad file descriptor


I've tested on the latest trunks on both 2.7 and 3.2. I've also tested on 2.6 and 3.1.

I can write a patch that fixes it if the bug is accepted.
