Review Comment:
When DNS resolution returns the truncate response, this function will
establish TCP connection and return the complete response. However, the
complete response can easily exceed the RECV_BUFFER_SIZE, causing the
resolution to fail, so I wrote a simple solution to solve this problem. There
are two better solutions. One is to recycle the buffer and finally splice the
buffer. The second is to use molloc to create a length that matches the
response. I would like to ask if there is a better solution. @yamt
