New submission from Jacques Grove <jacq...@tripitinc.com>:
In ssl.py of Python 2.6.1 we have this code in SSLSocket.__init__():
if do_handshake_on_connect:
timeout = self.gettimeout()
try:
self.settimeout(None)
self.do_handshake()
finally:
self.settimeout(timeout)
The problem is, what happens if the remote end (server) is hanging when
do_handshake() is called? The result is that the user-requested timeout
will be ignored, and the connection will hang until the TCP socket
timeout expires.
This is easily reproducable with this test code:
import urllib2
urllib2.urlopen("https://localhost:9000/";, timeout=2.0)
and running netcat on port 9000, i.e.:
nc -l -p 9000 localhost
If you use "http" instead of "https", the timeout works as expected
(after 2 seconds in this case).
