根因分析

通道从未关闭，且没有 goroutine 发送或接收，导致其永远被持有。

English

A channel is never closed and no goroutine is sending or receiving, causing it to be held forever.

解决方案

  1. 90% 成功率 
    ch := make(chan int)
// Ensure it's closed eventually
defer close(ch)
// or use a worker that exits
  2. 85% 成功率 
    ctx, cancel := context.WithCancel(context.Background())
ch := make(chan int)
go func() {
    select {
    case <-ctx.Done():
        close(ch)
    case v := <-ch:
        // process
    }
}()
cancel()

无效尝试

常见但无效的做法:

  1. 100% 失败

    Channels are not garbage collected if referenced; GC doesn't force close.

  2. 90% 失败

    Nil channel blocks forever; doesn't release resources.

  3. 80% 失败

    Leaks accumulate, leading to memory exhaustion.
