Here's a transcript which demonstrates the blocking behavior:
>>> import socket
>>> import time
>>> import ssl
>>> s = ssl.wrap_socket(socket.socket())
>>> s.connect(('localhost', 8443))
>>> s.send('GET /async.rpy HTTP/1.1\r\n\r\n')
27
>>> s.setblocking(False)
>>> a = time.time(); s.recv(1024); b = time.time()
'HTTP/1.1 200 OK\r\nTransfer-Encoding: chunked\r\nDate: Thu, 02 Sep 2010 11:51:03 GMT\r\nContent-Type: text/html\r\nServer: TwistedWeb/10.1.0+r29954\r\n\r\n4c\r\n<html><body>Sorry to keep you waiting.</body></html>\r\n0\r\n\r\n'
>>> print b - a
4.13403391838
>>>
(This can be reproduced using any web server which is a bit slow in responding; it's very obvious here because I used a server that intentionally waits several seconds before generating a response).

It was corrected between 2.6.5 and 2.6.6 (see r79291 and also potentially r80453). Here, on the 2.6 maintenance branch: >>> import socket, time, ssl >>> s = ssl.wrap_socket(socket.socket()) >>> s.connect(('linuxfr.org', 443)) >>> s.setblocking(False) >>> s.recv(1024) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/antoine/cpython/27/Lib/ssl.py", line 219, in recv return self.read(buflen) File "/home/antoine/cpython/27/Lib/ssl.py", line 138, in read return self._sslobj.read(len) ssl.SSLError: [Errno 2] _ssl.c:1348: The operation did not complete (read) Can you check with 2.6.6 or the release26-maint SVN head? |

Hm. I must have been testing with old versions, since I can't reproduce this now. Sorry for the noise. |
