使用buffer对象池(sync.Pool)需要着重关注引用问题

sync.Pool可以在高并发场景下提高吞吐能力,但是如果使用不当会导致严重的问题。这里详细梳理一下这次遇到的问题。

# 前言

之前测试仿真环境总是发生丢body的问题,经过长时间的排查,终于发现了原因。我们网关的Client用的是fasthttp,测试仿真环境是使用nginx自建的LB。当业务发版的时候nginx会reload配置文件,本来这个过程是没有问题的。但是,由于fasthttp实现的原因无法感知到server端的连接断开,从而导致client丢失了body。具体的详情可见这个issue

# 原始代码

为了解决丢body的问题,我们只能改为使用buffer。具体的实现如下:

func (c *Context) BodyBuffer() (*bytes.Buffer, error) {
   if v, ok := c.Get("BB"); ok {
      return v.(*bytes.Buffer), nil
   }
 
   buff := initvar.BufPool.Get().(*[]byte)
   buffer := initvar.BufferPool.Get().(*bytes.Buffer)
   buffer.Reset()
 
   _, err := io.CopyBuffer(buffer, c.Request.Body, *buff)
   if err != nil {
      return nil, err
   }
 
   initvar.BufPool.Put(buff)
   initvar.BufferPool.Put(buffer)
   c.Set("BB", buffer)
   return buffer, nil
}

结果,在线上有一个服务反馈他们有一个接口收到的RequestBody中混入了其他的数据。收到反馈后我们重新Review这段代码,迅速想到这里sync.Pool的使用存在问题。

这里我们在Put后又返回了buffer的指针,就造成多个Request公用一个buffer,自然就会导致某个Request中混入其他Request的Body。

# 修正

定位到问题后,我们迅速的进行了修改。 但是,万万没想到,又大意了!

func (c *Context) BodyBytes() ([]byte, error) {
   if v, ok := c.Get("BB"); ok {
      return v.([]byte), nil
   }
 
   buff := initvar.BufPool.Get().(*[]byte)
   buffer := initvar.BufferPool.Get().(*bytes.Buffer)
   defer initvar.BufPool.Put(buff)
   defer initvar.BufferPool.Put(buffer)
 
   buffer.Reset()
   _, err := io.CopyBuffer(buffer, c.Request.Body, *buff)
   if err != nil {
      return nil, err
   }
 
   c.Set("BB", buffer.Bytes())
   return buffer.Bytes(), nil
}

可以看到,我们为了解决原始代码的问题,想着在Put之前取出Bytes返回。但是,这里的Bytes函数读取的是Buffer中的属性里的一个[]byte,所以就导致仍然存在问题。

# 重现

为了验证我们的猜想,我们写了下面的代码进行验证,最终的输出确实可以看到Body里混入了其他数据。

func main() {
	pool := sync.Pool{New: func() interface{} {
		return new(bytes.Buffer)
	}}

	readBytes := func(src io.Reader) []byte {
		buffer := pool.Get().(*bytes.Buffer)
		defer pool.Put(buffer)

		buffer.Reset()
		_, err := io.Copy(buffer, src)
		if err != nil {
			fmt.Println(err)
		}

		return buffer.Bytes()
	}

	aaa := []string{
		"{\"data\":{\"pri\":\"IwtsnydXLqUzECkCxfi5WmQxQMoVSHiCT0NIOmkqPO\\/vhwb9uez0kkFlKuCRTvdeNpM\\/LE0tOCYxEB9DBVGqj4MZi2QRJuy0wQq75637cX9fUe69zyzS0dFZGcG6robTXMhBqykgbCn+aEa7wfuxJ1HEb7SZZyaJpZv8D4ztKC4\\/Yblr0xBVLl0Ltw5UJ9aGHg7JpSWZvmLuFTQ8\\/GwAdjBX4yznE8GzutTLWQrETLHdBRkx9y3Vq8Kauvq8QsXbVSsXqcX2nMn6r8I\\/TOHtAQRQwDSTfoZ5TOkz9ZckxPCgku8b2yhgQcALs8VkfYN0iZPA4L8m+Ed2WJsAtare6A==\",\"fingerprint\":\"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
