use Swoole\Coroutine\Channel;
use Swoole\Runtime;

require_once __DIR__.'/vendor/autoload.php';

Runtime::enableCoroutine(true, SWOOLE_HOOK_ALL);

$http = new Swoole\Http\Server("127.0.0.1", 7501, SWOOLE_PROCESS);
$http->on('start', function (Swoole\Server $server) {
    file_put_contents(__DIR__ . '/master.pid', (string)$server->master_pid);
});
$http->on('request', function ($request, $response) {
    $response->end('hello');

$http->set([

    'worker_num' => 1,
    'reload_async' => false,

$http->addProcess(new Swoole\Process(function ($process) use ($http) {
    $signal = true;
    $sleep = new Channel();
    Swoole\Coroutine::create(function () use(&$signal, $sleep) {
        defer(function () {var_dump('收到退出信号 1 -->'.date('s'));});
        while (true) {
            $ret = Coroutine\System::waitSignal(SIGTERM,-1);
            if($ret) {
                $signal = false;
                //收到结束信号
                $sleep->push(true);
                break;
            }
        }

        while (true) {

            if($ret) break;
        }
    });
    while ($signal) {
        if($sleep->pop(1)) {
            var_dump('取消sleep -->'.date('s'));
            break;
        }
        //搞事情
    }
    echo 'process stop'.PHP_EOL;
}, false, 2, 1));

$http->start();

```

### 你期待的结果是什么？实际看到的错误信息又是什么？
给master进程15信号后，期待打印：
```bash
[2022-03-18 11:13:12 #5109.1] INFO  Server is shutdown now
string(26) "收到退出信号 1 -->12"
string(26) "收到退出信号 2 -->12"
string(26) "取消sleep --> -->12"
```
实际打印：
```bash
[2022-03-18 11:13:12 #5109.1] INFO  Server is shutdown now
string(26) "收到退出信号 2 -->12"
```
