使用React / Ratchet,pthreads无法正常工作

问题描述 投票:2回答:1

我正在尝试为Ratchet WebSocket应用程序添加pecl-pthreads多线程支持。

这是我的申请:

<?php
namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Chat implements MessageComponentInterface
{
    protected $clients;
    public function __construct()
    {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn)
    {
        $this->clients->attach($conn);
        echo "New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from, $msg)
    {
        $dataIn = json_decode($msg);
        switch ($dataIn->type) {
            case 'test1':
                echo '+t1 block start' . date(' H:i:s') . "\n";
                $test1 = new Test1();
                $test1->start();
                echo '+t1 block end' . date(' H:i:s') . "\n";
                break;
            case 'test2':
                echo '-t2 block start' . date(' H:i:s') . "\n";
                $test2 = new Test2();
                $test2->start();
                echo '-t2 block end' . date(' H:i:s') . "\n";
                break;
        }
    }

    public function onClose(ConnectionInterface $conn)
    {
        $this->clients->detach($conn);
        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e)
    {
        echo "An error has occurred: {$e->getMessage()}\n";
        $conn->close();
    }
}

这是Test1.php的内容:

<?php
namespace MyApp;
class Test1 extends \Thread
{
    public function run()
    {
        echo '#Test1 thread start' . date(' H:i:s') . "\n";
        for ($i = 0; $i < 2; $i++) {
            echo 1 . date(' H:i:s') . "\n";
            sleep(10);
        }
        echo '#Test1 thread end' . date(' H:i:s') . "\n";
    }
}

这是Test2.php的内容:

<?php
namespace MyApp;
class Test2 extends \Thread
{
    public function run()
    {
        echo '#just Test2 run' . date(' H:i:s') . "\n";
    }
}

这是JavaScript代码:

var Websocket = new function () {
    var ws
    this.init = function () {
        ws = new WebSocket(wsURL + '/test')
        ws.onclose = function () {
            setTimeout('Websocket.init()', 1000)
        }
    }
    this.test1 = function () {
        var token = {
            type: 'test1'
        }
        ws.send(JSON.stringify(token))
    }
    this.test2 = function () {
        var token = {
            type: 'test2'
        }
        ws.send(JSON.stringify(token))
    }
}
$(document).ready(function () {
    Websocket.init()
})

var startTest = function () {
    Websocket.test2()
    Websocket.test2()
    Websocket.test1()
    Websocket.test2()
    Websocket.test2()
}

问题是测试1线程阻塞了MyApp的onMessage方法。

当我使用浏览器连接到我的应用程序并运行JavaScript startTest()函数时,我得到此CLI应用程序输出:

-t2 block start 20:08:48
#just Test2 run 20:08:48
-t2 block end 20:08:48
-t2 block start 20:08:48
#just Test2 run 20:08:48
-t2 block end 20:08:48
+t1 block start 20:08:48
#Test1 thread start 20:08:48
+t1 block end 20:08:48
1 20:08:48                                                                                                                                                                                                                                     
1 20:08:58                                                                                                                                                                                                                                     
#Test1 thread end 20:09:08                                                                                                                                                                                                                     
-t2 block start 20:09:08                                                                                                                                                                                                                       
#just Test2 run 20:09:08                                                                                                                                                                                                                       
-t2 block end 20:09:08                                                                                                                                                                                                                         
-t2 block start 20:09:08                                                                                                                                                                                                                       
#just Test2 run 20:09:08                                                                                                                                                                                                                       
-t2 block end 20:09:08

如您所见,我将即时5条消息从浏览器发送到我的应用程序。但是在test1消息之后,执行onMessage方法会暂停,直到Test1线程执行结束。它是某种pthreads /棘轮错误还是我做错了什么?

您在一个连接上发送消息,这意味着您只有一个线程。如果您想检查多线程是否正常工作 - 您应该尝试在下一个浏览器窗口/选项卡中运行该JS。

当test1阻塞线程时,Cuz,否则消息(2个消息test2 left)正在队列中等待。但是,如果其他人将同时连接到服务器,他将不会被阻止 - 因为他将获得单独的线程。在这种情况下,这就是多线程的强大功能。
