bug: php8执行GatewayClient\Gateway::getAllGroupIdList();多次后，只能得到空数组

dignfei 更新于2021-05-01

用定时器不断执行 Gateway::getAllGroupIdList();刚开始有用，几分钟后只能得到空数组。Gateway::getAllClientIdCount()得到0

有没有办法销毁Gateway，重新连接？

尝试：定时器每3秒重复运行：

\GatewayClient\Context::clear();
Gateway::$registerAddress = '127.0.0.1:9138';
$aaa = Gateway::getAllUidList();

在php7.4.8没问题。在php8.0.3报错：

  thrown

php4.8不会这样。 php8开启jit会这样

现阶段,还是用php7.4,比较稳妥

有的包需要8.0才能运行，没办法

找到了原因，这个方法，在php8中运行多次后会出错:
GatewayClient\GatewayProtocol的encode方法：
{

    /**
     * 获取整个包的 buffer
     *
     * @param mixed $data
     * @return string
     */
    public static function encode($data)
    {
        $flag = (int)is_scalar($data['body']);
        if (!$flag) {
            $data['body'] = serialize($data['body']);
        }
        $data['flag'] |= $flag;
        $ext_len      = strlen($data['ext_data']);
        $package_len  = self::HEAD_LEN + $ext_len + strlen($data['body']);
        return pack("NCNnNnNCnN", $package_len,
                $data['cmd'], $data['local_ip'],
                $data['local_port'], $data['client_ip'],
                $data['client_port'], $data['connection_id'],
                $data['flag'], $data['gateway_port'],
                $ext_len) . $data['ext_data'] . $data['body'];
    }

但是不知道是哪里错了，需要重复运行多次之后才会出错
