Question

我正在使用boto从S3存储桶上传和下载数据。我首先检查密钥存在，然后按如下方式调用下载到boto文件api。

    @retry_decorator
    def _get_data_to_file(self, src_key_object, file_name):
    try:
        s_key.get_contents_to_filename(file_name)
    except Exception, fault:
        logger.traceback(fault)
        raise

retry_decorator是装饰器函数，有助于在调用失败时重试操作。我在追溯中发现了以下错误。

并继续进行类似的错误重试。我观察到的是第一次回溯显示套接字错误，而后续追踪相同的调用显示其他东西..

任何人都可以帮助理解为什么我可以在重试后执行调用..？

boto key.get_content抛出socket.error然后重试失败
