New submission from Charles-François Natali:
test_ssl tests calling connect_ex don't handle unreachable servers properly:
"""
test_ssl
Resource 'svn.python.org' is not available
Resource 'svn.python.org' is not available
test test_ssl failed -- Traceback (most recent call last):
File "/srv/buildbot/buildarea/2.7.bolen-ubuntu/build/Lib/test/test_ssl.py",
line 246, in test_connect_ex
self.assertEqual(0, s.connect_ex(("svn.python.org", 443)))
AssertionError: 0 != None
"""
support.transient doesn't help here since no exception is raised.
Note that I'm not sure that connect_ex returning None is normal in the first
place...
There's a related failure on OpenBSD/NetBSD buildbots:
"""
test_timeout_connect_ex (test.test_ssl.NetworkedTests) ... ok
======================================================================
ERROR: test_non_blocking_connect_ex (test.test_ssl.NetworkedTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File
"/home/cpython/buildslave/3.x.snakebite-openbsd51-amd64-1/build/Lib/test/test_ssl.py",
line 685, in test_non_blocking_connect_ex
select.select([], [s], [], 5.0)
OSError: [Errno 22] Invalid argument
"""
I guess that connect() can't succeed because of an unreachable host/connection
refused, and the subsequent select() fails with EINVAL. This is most likely a
kernel bug, select should report the socket as ready for write (one could then
use getsockopt() to find the actual error).
