python之Boto 在 ssl.c 中不断崩溃

当我们尝试打开连接时，每 3 个连接(大约)boto 崩溃一次。

我已经在它离开 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. 

这里是相关的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，它总是 PY_SSL_VERSION_SSL23，我认为 SSL_CTX_new 由于某种原因失败了。

任何想法可能是错误的？

请您参考如下方法:

原来这是由于我们加载的其中一个证书在某种程度上可能是错误的，奇怪的是为什么它不是每次都崩溃。

无论如何，删除证书解决了问题。
