library's Introduction

Swoole Library

Dockerized Local Development

First, run one of the following commands to install development packages using Composer:

docker run --rm -v "$(pwd)":/var/www -ti phpswoole/swoole composer update -n

# or, use the official Composer Docker image:
docker run --rm -v "$(pwd)":/app -ti composer update -n --ignore-platform-reqs

# or, use the local Composer if installed:
composer update -n --ignore-platform-reqs

Next, you need to start Docker containers:

docker compose up -d

Alternatively, if you need to rebuild some Docker image and to restart the containers:

docker compose build --progress plain --no-cache
docker compose up -d --force-recreate

Now you can create a bash session in the app container:

docker compose exec app bash

And run commands inside the container:

composer test

Or you can run commands directly inside the app container:

docker compose exec app composer test

Examples

Once you have Docker containers started (as discussed in previous section), you can use commands like following to run examples under folder examples.

Examples of Database Connection Pool

docker compose exec app php examples/mysqli/base.php
docker compose exec app php examples/pdo/base.php
docker compose exec app php examples/redis/base.php

Examples of FastCGI Calls

There is a fantastic example showing how to use Swoole as a proxy to serve a WordPress website using PHP-FPM. Just open URL http://127.0.0.1 in the browser and check what you see there. Source code of the example can be found here.

Here are some more examples to make FastCGI calls to PHP-FPM:

docker compose exec app php examples/fastcgi/greeter/call.php
docker compose exec app php examples/fastcgi/greeter/client.php
docker compose exec app php examples/fastcgi/proxy/base.php
docker compose exec app php examples/fastcgi/var/client.php

Third Party Libraries

Here are all the third party libraries used in this project:

The FastCGI part is derived from Composer package lisachenko/protocol-fcgi.

You can find the licensing information of these third party libraries here.

base.php 里
加上配置 ->withDriver('pgsql'),
注释掉 ->withCharset('utf8mb4')

PDOPool.php里
注释掉 -"charset={$this->config->getCharset()}"
仍报上边的错误...

set_charset() should be called after confirming there aren't any connection errors

library/src/core/Database/MysqliPool.php

Line 42 in 9ba575a

$mysqli->set_charset($this->config->getCharset());

Roadmap: Swoole Library 5.2

Changed

Refactor method \Swoole\Database\PDOStatementProxy::setFetchMode().
Refactor method \Swoole\MultibyteStringObject::substr().
Refactor method \Swoole\FastCGI\Message::withBody() from public function withBody($body): self; to public function withBody(string|\Stringable $body): self;.
Fix method \Swoole\MultibyteStringObject::chunk(), and update the parent method if needed.

Miscellaneous

Errors ignored by PHPStan (check file ./phpstan.neon.dist for details)

Is it possible to create a PDOProxy object from an existing PDO connection?

As you can guess, I am trying to integrate an existing db framework into some Swoole based framework in a very lazy and hacky way. I tried new PDOProxy($existingPDO) in a hurry but of course it didn't work. It says it needs a callable but I couldn't figure out what kind callable it's talking about.

That existing PDO was already pulled from the connection pool and I got the real PDO object using the __getObject() method of the PDOProxy class. What I'm trying to do is to put that real pdo back to the pool converting to a PDOProxy object in some separate place of the code.

Exception on PDOStatementProxy+fetch

Call fetch on PDOStatementProxy when there is no result in db throws PDOException instead of returning value(false).

$pdo = new PDO('mysql:host=localhost;dbname=', '', '');
$stmt = $pdo->query('SELECT id FROM user WHERE 1=0');   
$result = $stmt->fetch();   
var_dump($result);

$pdoProxy = new \Swoole\Database\PDOProxy(function() {   
   return new PDO('mysql:host=localhost;dbname=', '', '');   
});
$stmt = $pdoProxy->query('SELECT id FROM user WHERE 1=0');   
$result2 = $stmt->fetch();
var_dump($result2);

Some external dependencies still?

Swoole\ConnectionPool creates a new instance of Swoole\Coroutine\Channel which doesn't exist in the project.

Same goes for Swoole\Coroutine\Server which uses the non-existent class Swoole\Coroutine\Socket.

And the same goes for Swoole\Coroutine\Http\Client.

I discovered this with Psalm (but you could use PHPStan or Phan to find the same).

PDOStatementProxy: fetch mode doesn't allow any extra arguments

$stmt->setFetchMode(PDO::FETCH_NUM);
Using setFetchMode with only 1 argument causes the following warning:

Warning: PDOStatement::setFetchMode(): SQLSTATE[HY000]: General error: fetch mode doesn't allow any extra arguments in @swoole-src/library/core/Database/PDOStatementProxy.php on line 48

setFetchMode doesnt support null as second/third argument.
The assignment of $classNameObject and $ctorarfg should be checked to make the proper call of setFetchMode on $this->__object

library/src/core/Database/PDOStatementProxy.php

Lines 121 to 125 in 6527488

 public function setFetchMode(int $mode, $classNameObject = null, array $ctorarfg = []): bool 

 { 

 $this->setFetchModeContext = [$mode, $classNameObject, $ctorarfg]; 

 return $this->__object->setFetchMode($mode, $classNameObject, $ctorarfg); 

 }

gitcode 或者gitee 也镜像一份呗，解决查看github例子间歇性打不开

缘由：文档中 https://github.com/swoole/library/blob/master/src/core/Coroutine/WaitGroup.php 中的例子，点击链接，间歇性打不开。
解决办法：使用代理、或者使用镜像

最佳方案：使用镜像

这个也需要镜像： https://github.com/swoole/docs.git （查看例子方便）

mysql set_opt should be called before connecting

https://github.com/swoole/library/blob/0f250bc7e7451992e0de103f07b284996feba07f/src/core/Database/MysqliPool.php

In current version, set_opt called after connect so none of these options work. This should be replaced with:

$mysqli = new mysqli();
foreach ($this->config->getOptions() as $option => $value) {
    $mysqli->set_opt($option, $value);
}
$mysqli->real_connect(....);

CURLOPT_UNIX_SOCKET_PATH is not supported

This part with curl hooks enabled:

 \curl_setopt($ch, CURLOPT_UNIX_SOCKET_PATH, '/var/run/docker.sock');

results into following error message:

Fatal error: Uncaught Swoole\Curl\Exception: swoole_curl_setopt(): option[10231] is not supported in @swoole-src/library/core/Curl/Handler.php:655

Is there a chance that this can be implemented?

Question: Pretty permalinks example?

In Apache we have

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

and in NGINX we have try_files $uri $uri/ /index.php?$args;.

What is the appropriate example with Swoole Proxy to support such behavior?

TypeError: Swoole\Coroutine\Http\Client::setHeaders(): Argument #1 ($headers) must be of type array, null given

Fatal error: Uncaught TypeError: Swoole\Coroutine\Http\Client::setHeaders(): Argument #1 ($headers) must be of type array, null given in @swoole-src/library/core/Coroutine/Http/functions.php:39

Barrier类修改

以下情况下不会抛出协程错误异常，正常执行

执行的任务中没有发生协程切换

修改后的类

use Swoole\Coroutine;

    private $cid = -1;

    private $timer = -1;

    private static $cancel_list = [];

}

Where was the Amp driver moved to?

There was a file on https://github.com/swoole/library/blob/master/src/Swoole/Driver/Amp.php that was supposed to be the Driver for Amp. It is no longer there. Any idea of where it got moved to?

PDOStatement::bindParam() expects parameter 1 to be string

I am used to coding:

$sql = 'select name from user_account where email=?';
$stmt = $db->prepare($sql);
$stmt->bindParam(1, $email, PDO::PARAM_STR);

But it's throwing an exception:

PDOStatement->bindParam() @swoole-src/library/core/Database/PDOStatementProxy.php:138
PHP TypeError:  PDOStatement::bindParam() expects parameter 1 to be string, int given in @swoole-src/library/core/Database/PDOStatementProxy.php on line 138

I suspect that __object in abstract class is the cause. Another way is working fine:

$sql = 'select name from user_account where email=:email';
$stmt = $db->prepare($sql);
$stmt->bindValue('email', $email, PDO::PARAM_STR);

I'm using the following swoole:

$ php --ri swoole

For Postgres PDO Connection Pool, the "charset" option gives error.

What did you do? If possible, provide a simple script for reproducing the error.

// db_connection_pool.php

//const POSTGRES_SERVER_DRIVER = 'pgsql'; // I get warning "Already defined" if i uncomment it
const POSTGRES_SERVER_HOST = 'localhost';
const POSTGRES_SERVER_PORT = 5432;
const POSTGRES_SERVER_DB = 'swooledb';
const POSTGRES_SERVER_USER = 'postgres';
const POSTGRES_SERVER_PWD = 'passwd123';

function create_db_connection_pool() {
    return new PDOPool(
            (new PDOConfig())
                ->withDriver(POSTGRES_SERVER_DRIVER)
                ->withHost(POSTGRES_SERVER_HOST)
                ->withPort(POSTGRES_SERVER_PORT)
                // ->withUnixSocket('/tmp/mysql.sock')
                ->withDbName(POSTGRES_SERVER_DB)
                //->withCharset('utf8mb4')
                ->withUsername(POSTGRES_SERVER_USER)
                ->withPassword(POSTGRES_SERVER_PWD)
        );
}

Also, tried ...

->withCharset('utf8mb4')

And, from inside a class, i make call to "create_db_connection_pool()" funtion:

include(db_connection_pool.php);

protected $conn_pool_swoole;

$this->conn_pool_swoole = create_db_connection_pool();
$pgsql_conn_swoole = $this->conn_pool_swoole->get();

What did you expect to see?

Creation of connection pool without any Fatal Error

What did you see instead?

And when used ->withCharset(''), the error became:

I can connect postgres using same credentials and using open-smf package for connection pool for swoole.

I suspect that the issue is in the definition of dsn string in constructor of PDO() which is returned from inside the constructor of PDOPool class.

Unlike mysql, "postgres" does not take charset='something' as part of dsn string therefore it should not be concatenated if database driver is set as "pgsql" instead of "mysql".

For postgres, charset can be set using "options" key of dsn string, as below:

options='--client_encoding=UTF8'

Feature request: Proroutines (?)

Hi 👋

I was zapping my social feed when a suddenly found this: https://github.com/clue/reactphp-pq
Looks interesting because of the easiness it provides (Laravel surfs a lot on this), I mean...
I know it is "just" multi-processing and Swoole already does a really good job, but!!

What about and API that treats a new process like if its a new "Coroutine"?

A Proroutine (or a better name) is like a Coroutine, but it is actually a new process and all of this could be just a sugar, in the library, around Pool and Manager?
Then whatever is blocking, like unimplemented I/O protocols or CPU-bound tasks, you can delegate to a Proroutine instead of a Coroutine. With the proper disclaimer that a Proroutine is not arbitrary created like a green-thread/coroutine.

Procroutines looks cool as well.

PDOException Original error code change

Hello,
We have an application using PDOProxy and PDO,
We have an inconsistency problem when trying to match the original PDOException error code.
https://github.com/swoole/library/blob/master/src/core/Database/PDOProxy.php#L61
This is how it is now
$exception = new PDOException($errorInfo[2], $errorInfo[1]);
should be
$exception = new PDOException($errorInfo[2], $errorInfo[0]);
since the original Error code is in position 0.
Thank you very much

Allowed memory size exhausted Curl CURLOPT_FILE

Hi!

When using curl with flag CURLOPT_FILE have allowed memory size exhausted issue on big responses.
Any idea how to fix it?

Swoole curl incorrect send cookie from COOKIEFILE/COOKIEJAR.

Hi.
Recently i discovered the php-swoole library and was surprised how easy it is to write high-performance applications with it in the paradigm familiar to php.

But in the module SWOOLE_HOOK_CURL i found that the library does not work correctly with cookie-files.

php-curl (libcurl) use Netscape-format of cookie-file, but SWOOLE_HOOK_CURL doesn't understand this format.
Even if we dont use cookies from php-curl, but let SWOOLE_HOOK_CURL create a cookie from scratch, SWOOLE_HOOK_CURL will not able to reuse cookies (new request will be executed with broken headers).

Working with a cookie is more complex than just taking the content of the Set-Cookie header and saving it to a file, then sending everything in the Cookie-header.
The server sends each cookie to the client as a separate Set-Cookie header with all service information (for example, lifetime, domain, etc.), and the client must send only the name and contents of the cookie to the server, checking whether the lifetime has expired, whether the domain is correct and stuff like that. I am sure you know better than me how http-cookies work.
Example of how to work correctly with cookie-file can be seen in the library amphp/http-client-cookies.

https://www.php.net/manual/en/function.curl-setopt.php
CURLOPT_COOKIEFILE file to read cookies before request.
CURLOPT_COOKIEJAR file where cookies are written after curl_close().

Hopefully these bugs will be fixed and php-swoole-curl will handle cookie-files correctly.

Thank you for your work.

Cannot execute queries while other unbuffered queries are active.

Error stack

Uncaught PDOException: Cannot execute queries while other unbuffered queries are active.  Consider using PDOStatement::fetchAll().  Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. in @swoole-src/library/core/Database/PDOStatementProxy.php:64
Stack trace:
#0 /acme/vendor/laravel/framework/src/Illuminate/Database/Connection.php(335): Swoole\Database\PDOStatementProxy->__call('execute', Array)
#1 /acme/vendor/laravel/framework/src/Illuminate/Database/Connection.php(677): Illuminate\Database\Connection->Illuminate\Database\{closure}('select `order_i...', Array)
#3 /acme/vendor/laravel/framework/src/Illuminate/Database/Connection.php(340): Illuminate\Database\Connection->run('select `order_i...', Array, Object(Closure))

What I tried

change to FetchAll , not working
Set atrribute MYSQL_ATTR_USE_BUFFERED_QUERY to true for statement, not working
Close cursor as this cannot-execute-queries-while-other-unbuffered-queries suggests. not working
