# 警告：检测到通道泄漏（chan int，goroutine 3）

- **ID:** `go/channel-leak-without-close`
- **领域:** go
- **类别:** resource_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

通道从未关闭，且没有 goroutine 发送或接收，导致其永远被持有。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 1.21 | active | — | — |

## 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

- **** — Channels are not garbage collected if referenced; GC doesn't force close. (100% 失败率)
- **** — Nil channel blocks forever; doesn't release resources. (90% 失败率)
- **** — Leaks accumulate, leading to memory exhaustion. (80% 失败率)
