【go】golang time.NewTicker 内存泄漏?

  1. 程序运行内存不停增加 , 使用 pprof 查看,怀疑是time.NewTicker问题

部分代码

func (spider *Spider) downloaderTotalPlatform()  {

rconn := redis.GetConn()

defer rconn.Close()

queue := db.Queue{}

for {

v, err := rconn.Do("LPOP", db.RedisListList)

if err != nil {

log.Println(err.Error())

continue

}

if v == nil {

//暂停 5 秒

<-time.Tick(time.Second * 5)

continue

}

body, err := downloaders(v, &queue)

if err != nil {

log.Println(err.Error())

continue

}

if body == nil {

continue

}

spider.ChanParsers <- &Parser{

Body:body,

Queue:queue,

}

}

}

看看Tick的注释就知道了:

// Tick is a convenience wrapper for NewTicker providing access to the ticking

// channel only. While Tick is useful for clients that have no need to shut down

// the Ticker, be aware that without a way to shut it down the underlying

// Ticker cannot be recovered by the garbage collector; it "leaks".
