The buildslaves "i386 Ubuntu" have been exhibiting some strange behaviour for some time now: ====================================================================== ERROR: test_protocol_sslv2 (test.test_ssl.ThreadedTests) Connecting to an SSLv2 server with various client options ---------------------------------------------------------------------- Traceback (most recent call last): File "/scratch/pybot-buildarea/2.7.klose-ubuntu-i386/build/Lib/test/test_ssl.py", line 879, in test_protocol_sslv2 try_protocol_combo(ssl.PROTOCOL_SSLv2, ssl.PROTOCOL_SSLv2, True) File "/scratch/pybot-buildarea/2.7.klose-ubuntu-i386/build/Lib/test/test_ssl.py", line 751, in try_protocol_combo ciphers="ALL", chatty=False) File "/scratch/pybot-buildarea/2.7.klose-ubuntu-i386/build/Lib/test/test_ssl.py", line 703, in server_params_test s.connect((HOST, server.port)) File "/scratch/pybot-buildarea/2.7.klose-ubuntu-i386/build/Lib/ssl.py", line 295, in connect self.ca_certs, self.ciphers) SSLError: _ssl.c:312: Invalid SSL protocol variant specified.

It seems its OpenSSL library refuses to allocate any SSL context for the SSL v2 protocol. Is it some kind of patch added by the Ubuntu OpenSSL maintainers in order to disable SSLv2 entirely? |

> see https://lists.ubuntu.com/archives/ubuntu-devel/2010-July/031010.html Why are they doing that? SSLv2 ciphers are disabled by default anyway (in newer OpenSSL versions, that is). If Ubuntu is adding hacks to the libraries they're packaging, I'm not willing to add a workaround to the test suite in order for the tests to pass. |

I'm trying to skip, rather brutally, the failing tests in r83727. |

Committed similar skips for 2.7 in r83728. Let's see what the buildbot says. |

Things are apparently fine now. |
