swow/swow

Coroutine-based cross-platform concurrent I/O engine.

English | 中文

🚀 Swow is a multi-platform support and coroutine-based engine with a focus on concurrent I/O

👾 Design Philosophy

Swow is committed to using the smallest C core and most of the PHP code to support PHP high-performance network programming, which determines that it is more about providing powerful secondary development capabilities by seamlessly integrating PHP code and C kernel, while ensuring critical performance.

In addition, it provides a variety of debugging mechanisms and powerful and low-threshold debugging tools, which can ensure that developers are free from the trouble of BUGs as much as possible, and ordinary developers can also have the ability to debug near the level of experts with the help of tools, so as to maximize development efficiency.

🎮 Installation

Like any open source project, Swow always provides the strongest stability and features in the newest release, please try to ensure that you are using the latest version.

🔎 Requirements

• Common operating systems such as Linux, Windows, macOS, etc. Almost same as libuv
• PHP 8.0.0 or above, the latest version is recommended

👨‍🎤 By Composer

swow's Issues

Support for Apple Silicon M1

Apple Macbook M1 编译失败。是不是还不支持？

Windows安装手动构建 swow dll 文档链接打不开

1.Windows安装
手动构建见文档
文档链接 打不开
2.官方 swow.dll 在哪里下

[discussion] (PHP代码实现的功能能不能单列出来)

1. lib 库里PHP代码的功能和扩展实现的功能都在一个命名空间下，搞不清楚是扩展提供的还是PHP库提供的
2. 如果开发者不喜欢PHP库的一些实现方式，它就显得有点多余。只要有足够健壮高效的底层，大家都喜欢造上层轮子
3. 为什么不作为单独的官方库实现，可以composer引入使用，也可以作为框架开发者的参考

我使用 MAC OS 构建时发生了错误

环境:

$> sw_vers
ProductName:	Mac OS X
ProductVersion:	10.13.6
BuildVersion:	17G65

$> php -v
PHP 7.4.10 (cli) (built: Sep  3 2020 18:20:30) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.10, Copyright (c), by Zend Technologies

我执行php ./vendor/bin/swow-builder 命令进行构建时发生报错如下:

然后我又重新编译并且打印出日志 php ./vendor/bin/swow-builder --rebuild --show-log

发现 ./vendor/swow/swow/ext/deps/libcat/tools/cpu_count.sh , ./vendor/swow/swow/ext/clean.sh , ./vendor/swow/swow/ext/deps/libcat/tools/cleaner.sh
文件的换行符为CRLF (\r\n) 并非 LF (\n) 所以导致我无法完成编译

然后我使用dos2unix 命令，进行换行符转换，就可以正常编译了

dos2unix ./vendor/swow/swow/ext/deps/libcat/tools/cpu_count.sh
dos2unix ./vendor/swow/swow/ext/clean.sh
dos2unix ./vendor/swow/swow/ext/deps/libcat/tools/cleaner.sh

不知道我能不能直接将这三个文件的换行符转换为 LF，我抽空测试下转换后在 windows 下编译是否正常

大佬们看看有没有啥更好的解决方案

何时可以正式的使用？

Windows version extension

windows上如果编译安装？

[discussion] (单进程模型的问题)

swow现在是不是和node一样的单进程模型，无法对多核cpu充分利用，如果是这样有什么好的解决办法吗？

希望编译扩展的时候，可以把php也静态编译

cli模式下更希望是可以像node、golang那样纯静态编译，带着有swow扩展的纯静态编译php-cli，发送给其它的机器也能运行，而不需要在机器上安装php环境，虽然有docker，但一通操作下载，镜像大小也要上GB，不知道我这样表达的是否清楚，欢迎讨论

这个项目是干啥的跟swoole有什么不同,文档什么时候完善,预计什么时候可用？

使用Stream函数创建https类型连接时没有hook到

具体复现：
使用guzzle包中的StreamHandler请求https站点时，fopen会阻塞。

[discussion] (建议废弃lib下面的内容，这些完全让php开发者自己去实现。专心维护ext的稳定性、性能、兼容性)

这是只是一个建议，要长远的支持下去，做的太多耗费的精力太多了，做的太多也容易产生更多的bug，即使很努力 也容易会给人一种很不稳定的影响。 建议尽量的少，保持非常好的灵活、稳定性、兼容性（类似workerman php5.3+都能用 ，并不是说需要支持5.x 只是表达着个库|扩展不挑环境 适应性很强）

关于stream_set_blocking阻塞疑惑

你好，关于stream_set_blocking设置为非阻塞之后还是阻塞的问题，我看了一下swow的代码，发现：

static int swow_stream_set_option(php_stream *stream, int option, int value, void *ptrparam) {
    // 省略
    /* always blocked */
    return PHP_STREAM_OPTION_RETURN_OK;  这里是没有操作的
}

我又看了一下php8这部分的源码，这里是：
oldmode = sock->is_blocked;
if (SUCCESS == php_set_sock_blocking(sock->socket, value)) {
sock->is_blocked = value;
return oldmode;
}
return PHP_STREAM_OPTION_RETURN_ERR;

php_set_sock_blocking 也是直接执行fcntl修改套接字的属性，请问这里为啥不能直接copy过去呢？

会支持多线程吗

如题
😄 😄 😄

SSL/TLS support ciphers/min_proto_version/max_proto_version/crypto_method...

Swow\Socket\enableCrypto 是否可以新增设置TLS版本选择 (目前测试版本是根据客户端自动的) 以及密码套件的设置

什么时候准备出一个think-swow

例如像think-swoole一样，因为这个在thinkphp6中使用多应用时无法正常路由，听说swow很强，希望以后能用上 think-swow 提供 windows和linux的高性能接口服务

为什么不用ffi呢？

为什么不直接使用php7.4以上的FFI直接调用，这样就可以完全用composer安装了。

Channels

Hi, thanks for supplying nice stuff.

Just tried the example for channels and selectors and doesn't work for me.
But the coroutines are just fine.

Does the examples are up to date with current version of code ?

swow 支持 PostgreSQL吗

swow 现在的版本支持 PostgreSQL 协程了吗？

WaitGroup的done方式似乎有个判断是错误的

这个判断会导致在协程内done的时候报错，这个判断是否不需要。
如果需要的话，只能是new Coroutine在resume()后执行done，此时协程已经结束。

README中路径问题

使用此方式安装时，最后一步程序会提示输入密码以使用root权限安装到系统，你可以选择不输入，安装程序仍会提供类似于以下的运行命令：

/usr/bin/env php -n -d extension=/path/to/vendor/swow/swow/ext/.build/swow.so --ri swow

即扩展的so文件输出到了你项目的vendor目录下，相当于扩展也拥有了版本控制，你可以为你的每个项目指定不同版本的Swow，而无需全局使用同一个扩展so。

实际 swow.so 路径，是否为 /path/to/vendor/swow/swow/modules/swow.so。并未看到有 .build 文件夹

fibers会被合并到php 8.1，swow怎么办

fibers会被合并到php 8.1，不知道swow后面的路怎么走呢？个人感觉应该是php8.1出来之后，比如 mysql、mongdo、redis之类的软件肯定会出适配8.1的协程驱动，这是一种趋势，也是把php蛋糕做大的唯一途径，也是官方希望看到的。扩展毕竟非官方，没有官方支持很难去推广和普及，相比作者应该有自己的想法吧，可否一起讨论下

Mac编译时提示waring,执行php -m提示协程与操作opcode部分扩展不兼容

Ability to cancel I/O bound operations

Hello! Do you have any plans to implement ability to cancel I / O operations like GoLang does?

https://golang.org/pkg/context/

Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes.

I think it should be a core ability. It can be useful for services graceful shutdown and can be more consistent with I / O operations (like context.WithTimeout () can be used to cancel any I / O operation by timeout only in one way instead of many setTimeout APIs on Socket and etc.)

windows10,php 7.4开启swow拓展，composer有点小问题

windows10,php 7.4开启swow拓展 (v0.1.0-nightly20210910版本)
composer create-project hyperf/swow-skeleton
composer创建项目会有小问题，慢，且常报curl错误，关闭swow.dll拓展，composer使用正常。
然后再开启swow，可正常使用swow的hyperf

[discussion] swow 能与 workerman 搭配使用吗？

期望的效果

目前最期望的是 swow 的 coroutine 能和 workerman 搭配使用，如果能像 goroutines 那样方便就好了。

遇到的问题

在实际使用中，workerman timer 下使用 swow coroutine 协程化封装后的 socket 连接，

要么无法连接到 workerman 的 tcp server, 要么就是连上了无法发送出去数据。

我不太确定是不是我的姿势不对，还是说 swow 不能用于类似 workerman 这种用 pcntl fork 出来的多进程 worker 模式。

测试代码

PHP: 8.1.4
Swow: latest
Workerman: 4.0.33
Composer: 2.3.4

composer require workerman/workerman
composer require swow/swow:dev-develop

use Swow\Coroutine;
use Workerman\Timer;
use Workerman\Worker;
use Workerman\Protocols\Text;

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

// ------------------------------------------------------------------------------

$tcpAddr   = 'tcp://127.0.0.1:1234';
$tcpWorker = new Worker($tcpAddr);
$tcpWorker->count = 4;

$tcpWorker->onConnect = static function ($connection)
{
    echo "New Connection\n";
};

$tcpWorker->onClose = static function ($connection)
{
    echo "Connection closed\n";
};

$tcpWorker->onMessage = static function ($connection, $data)
{
    echo "Message received\n";

    Coroutine::run(static function () use ($connection, $data)
    {
        echo "Received data: $data\n";

        $connection->send("Hello $data \n");
    });
};

// ------------------------------------------------------------------------------

$task = new Worker();
$task->onWorkerStart = static function ($task) use ($tcpAddr)
{
    $timeInterval = 0.1;

    Timer::add($timeInterval, static function () use ($tcpAddr)
    {
        Coroutine::run(static function () use ($tcpAddr)
        {
            $client = stream_socket_client($tcpAddr, $code, $err, 3);

            if (!is_resource($client))
            {
                echo "Connection failed\n";
                return;
            }

            $data   = Text::encode(microtime(true));
            $length = strlen($data);
            $sended = fwrite($client, $data, $length);

            if ($sended !== $length)
            {
                echo "Send failed: $data\n";
            }

            $message = fread($client, 1024);

            echo "Finished: $message\n";

            fclose($client);
        });
    });
};

// ------------------------------------------------------------------------------

Worker::runAll();

php index.php start

New Connection
New Connection
New Connection
....

Warning: [Warning in R225] stream_socket_client(): Unable to connect to tcp://127.0.0.1:1234 (Socket connect has been canceled)
Stack trace:
#0 /.../test_swow/index.php(49): stream_socket_client('tcp://127.0.0.1...', 0, '', 3)

#2 {main}
  triggered in /.../test_swow/index.php on line 49
....

服务启动之后一直打印 New Connection，但是无其他输出。
直到手动停止服务时，会打印出大量的 Socket connect has been canceled 的警告

补充说明

项目实际环境远比上述代码复杂

但是很期望 swow corountine 能像 goroutines 一样简单省心

希望大佬们能给点指点

[discussion] 能否把这个拓展无缝替换swoole

能否不改变目前用到swoole项目代码的情况下直接加swow拓展行不行？我们目前有几个遗留项目使用的easy-swoole框架，其他是golang和laravel项目，我的点奥配置不好，用了两年的电脑丢掉挺可惜。因此想直接在windows下面不用docker,wsl,虚拟机，cygwin的情况下，只要满足开发需求即可，不需要实际linux的效果，因为最终测试和压测都是在部署环境进行。

[discussion] Starting a new project, should use Swow or Swoole?

Hello,

We're starting a new project that will include a number of microservices with critical performance requirements. Some HTTP servers and some WebSockets servers.

The question is, should we use Swow or Swoole since we have limited hardware resources and want to make the most of what we have and performance is of essence, and what should be the use cases for each of Swow and Swoole?

[discussion] PHP8.0 cURL windows支持: curl_exec返回false

已知使用PHP8.0.2-8.0.6官方devel-pack构建（这个条件可能没有影响）的swow的dll

在官方二进制发布PHP8.0.0-8.0.3二进制下的curl_exec返回值有问题

推测是发生了神奇的ABI变化， 没法判断具体原因

前来看官方发布的PHP8.0.6二进制使用目前任意devel-pack构建的dll都没有问题

建议遇到类似问题的小伙伴更新php到最新的patch版本

在gh更新操作系统镜像中的php版本之前，ci中的windows 8.0测试可能还是会红

stream_set_blocking似乎没有hook到

使用freedsx/ldap包，其中的stream_set_blocking没有hook到，会挂起直到超时返回。
swoole低版本也有这个问题，最新4.5.5版本是OK的。

[discussion] 上线时间线整一个怎么样？还有亿点点疑问。

1. 众所周知现在 swoole 对于除mysql/postgreSQL外的其他数据库 mongoDB\MsSqlserver无法支持协程,swow到时候要使用什么样的机制和方式来解决类似的问题，还是说任然需要厂商推动？

真的只有一点点
