当我们尝试打开连接时,每3个连接(大致)boto崩溃。
我在离开python之前打印了所有参数,并且在每个连接上参数都是相同的。
这是堆栈跟踪:
boto/sqs/connection.pyc in get_queue(self, queue_name)
292 :returns: The requested queue, or ``None`` if no match was found.
293 """
--> 294 rs = self.get_all_queues(queue_name)
295 for q in rs:
296 if q.url.endswith(queue_name):
boto/sqs/connection.pyc in get_all_queues(self, prefix)
281 if prefix:
282 params['QueueNamePrefix'] = prefix
--> 283 return self.get_list('ListQueues', params, [('QueueUrl', Queue)])
284
285 def get_queue(self, queue_name):
boto/connection.pyc in get_list(self, action, params, markers, path, parent, verb)
880 if not parent:
881 parent = self
--> 882 response = self.make_request(action, params, path, verb)
883 body = response.read()
884 boto.log.debug(body)
boto/connection.pyc in make_request(self, action, params, path, verb)
866 if self.APIVersion:
867 http_request.params['Version'] = self.APIVersion
--> 868 return self._mexe(http_request)
869
870 def build_list_params(self, params, items, label):
boto/connection.pyc in _mexe(self, request, sender, override_num_retries, retry_handler)
792 raise BotoServerError(response.status, response.reason, body)
793 elif e:
--> 794 raise e
795 else:
796 msg = 'Please report this exception as a Boto Issue!'
SSLError: _ssl.c:316: Invalid SSL protocol variant specified.
以下是相关的C代码:
PySSL_BEGIN_ALLOW_THREADS
if (proto_version == PY_SSL_VERSION_TLS1)
self->ctx = SSL_CTX_new(TLSv1_method()); /* Set up context */
else if (proto_version == PY_SSL_VERSION_SSL3)
self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */
else if (proto_version == PY_SSL_VERSION_SSL2)
self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */
else if (proto_version == PY_SSL_VERSION_SSL23)
self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */
PySSL_END_ALLOW_THREADS
if (self->ctx == NULL) {
errstr = ERRSTR("Invalid SSL protocol variant specified.");
goto fail;
}
我们打印了proto_version
并始终PY_SSL_VERSION_SSL23
,我认为SSL_CTX_new
由于某种原因失败了。
任何想法可能出错?

原来这是由于我们加载的一个证书在某种程度上可能是坏的,很奇怪为什么它不会每次都崩溃。
无论如何,删除证书解决了问题。

certifi最新版本存在一些问题,因此降级认证将解决问题
pip uninstall -y certifi && pip install certifi==2015.04.28
or
pip install requests[security]
