[issue21218] Test failure for test_ssl.test_default_ecdh_curve on OS X

[Jeff Ramnani]

New submission from Jeff Ramnani:

The unittest, test_ssl.test_default_ecdh_curve, is failing on OS X (and FreeBSD 9).

The test fails with the error message:
"""
======================================================================
ERROR: test_default_ecdh_curve (test.test_ssl.ThreadedTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/jramnani/code/cpython/Lib/test/test_ssl.py", line 2596, in test_default_ecdh_curve
    context.set_ciphers("ECDH")
ssl.SSLError: ('No cipher can be selected.',)

----------------------------------------------------------------------
"""

It looks to be related to issue, #21015 (changesets 3b81d1b3f9d1 and 869277faf3dc).


OS Info:
* Version: OS X 10.9.2
* OpenSSL version: OpenSSL 0.9.8y 5 Feb 2013


The problem looks like OpenSSL on OS X is reporting that it has ECDH when it does not.
