Workerman globalEvent 全局变量疑问

globalEvent 全局变量疑问

//// 这时候已经初始化操作
Worker::$globalEvent = new Event();

$worker = new Worker("http://0.0.0.0:8818");
$worker->count = 8;
$worker->reusePort = false;
Worker::runAll();

// Get column mapping for UI
foreach(static::getUiColumns() as $column_name => $prop){
    !isset($worker->{$prop}) && $worker->{$prop} = 'NNNN';
    $prop_length = \strlen((string) $worker->{$prop});
    $key = '_max' . \ucfirst(\strtolower($column_name)) . 'NameLength';
    static::$$key = \max(static::$$key, $prop_length);
}

// Listen.
if (!$worker->reusePort) {
    $worker->listen();
}

   /// 由于已经初始化，就能通过这里
   public function resumeAccept()
    {
        // Register a listener to be notified when server socket is ready to read.
        if (static::$globalEvent && true === $this->_pauseAccept && $this->_mainSocket) {
            if ($this->transport !== 'udp') {
                static::$globalEvent->add($this->_mainSocket, EventInterface::EV_READ, array($this, 'acceptConnection'));
            } else {
                static::$globalEvent->add($this->_mainSocket, EventInterface::EV_READ, array($this, 'acceptUdpConnection'));
            }
            $this->_pauseAccept = false;
        }
    }

// 但forkOneWorkerForLinux()看这里又是允许的
// Create a global event loop.
if (!static::$globalEvent) {
    $event_loop_class = static::getEventLoopName();
    static::$globalEvent = new $event_loop_class;
}

// Reinstall signal.
static::reinstallSignal();

//// 疑问：
因为master已经把mainSocket加入eventloop()了。
这时候globalEvent 已经被初始化，多个worker 进程会拷贝master的已经加入eventloop数据，这样不会出现问题？
//// 文档讲解了作用： https://www.workerman.net/doc/workerman/worker/global-event.html
/// 还是说我这种用法Worker::$globalEvent = new Event();本身就是不被允许的呢？
