Would you like php 7.4 Preloading? Would you like php coroutine? Today you can use them with Laravel because of Swoole. With LaravalFly, Laravel will begin like Django 3.0 to be fully async-capable.

LaravelFly is a safe solution to speeds up new or old Laravel 5.5+ projects, with preloading and coroutine, while without data pollution or memory leak. And it makes Tinker available online (use tinker while Laravel is responding requests from browsers).

Thanks to Laravel, Swoole and PsySh.

    • php7.2 + opcache + 5 workers for both fpm and laravelfly ( phpfpm : pm=static pm.max_children=5)
    • connection pool and coroutine mysql
  • Test date : 2018/10

Version Compatibility

  • Laravel 5.5 ~ 6.0
  • Swoole >4.2.13

Quick Start

1.

pecl install swoole

Make sure
extension=swoole.so
in config file for php cli, not for fpm.
Suggest:
pecl install inotify

2.

composer require "scil/laravel-fly":"dev-master"

3.

php vendor/scil/laravel-fly/bin/fly start

If you enable
eval(tinker())
and see an error about mkdir, you can start LaravelFly with sudo.

Now, your project is flying and listening to port 9501. Enjoy yourself.

Docker-compose

composer require "scil/laravel-fly":"dev-master"

php artisan vendor:publish --tag=fly-server

127.0.0.1:8080

you can edit this docker-compos file and use your own nginx conf

docker-compose -f vendor/scil/laravel-fly-local/docker/docker-compose.yml up -d

Events about LaravelFly

Using tinker when Laravel Working

For Dev

Recommended Packages

  • swlib/saber Coroutine HTTP client, based on
    Swoole\Coroutine\Http\Client
    .
    Browser-like cookie managment, multiple requests concurrent, request/response interceptors and so on.
    To ensure safety, set
    const LARAVELFLY_COROUTINE = true;
    in fly.conf.php.

Features and Behaviors

  • Same codes can run on PHP-FPM or LaravelFly. LaravelFly can be installed on your existing projects without affecting nginx/apache server, that's to say, you can run LaravelFly server and nginx/apache server simultaneously to run the same laravel project. The nginx conf swoolefallbackto_phpfpm.conf allow you use LaravelFlyServer as the primary server, and the phpfpm as a backup server which will be passed requests when the LaravelFlyServer is unavailable. Another nginx conf useswooleorfpmdependingonclients allows us use query string

    ?useserver= to select the server between swoole or fpm. That's wonderful for test, such as to use eval(tinker()) as a online debugger for your fpm-supported projects. Apache? There is a example Cooperate with Apache from laravel-s.
  • Moderate strategy: by default, each Third Party service provider is registered on server worker process (before the first request arrived at server) , booted in request.

  • By default, all Laravel official services are COROUTINE-FRIENDLY, including mysql and redis. You can make a service or object before any requests. There are two ways:

    • let the service or object live in multiple requests (only one instance of the service). LaravelFly named it WORKER SERVICE, WORKER OBJECT or COROUTINE-FRIENDLY SERVICE/OBJECT.
    • cloned the service or object in each request (one instance in one request).LaravelFly named it CLONE SERVICE or CLONE OBJECT. This way is simple, but often has the problem Stale Reference. This type is used widely by laravel-swoole and laravel-s, while used rarely by LaravelFly.
  • Extra speed improvements such as connection pool, middlewares cache, view path cache.

  • Check server info at /laravel-fly/info. (This feture is under dev and more infomations will be available.)

  • No support for static files any more, so use it with other servers. Conf examples: nginx or Apache

  • swoole-job,A Laravel job or event listener can be delivered into a swoole task process and executed at once

    artisan queue:work
    needless any more.
  • exit()
    or
    die()
    in an route action would output content to console or swoole log, and not make server die or reload. If you would like to change that behavior, fork LaravalFly and catch
    \Swoole\ExitException
    in
    LaravelFly\Map\Kernel::handle
    .
  • Support connection pool. There's only one connection available in each request.But if you use

    fly()
    or
    fly2()
    , you can use connections more than one.
  • functions

    fly()
    and
    fly2()
    which are like
    go()
    provided by golang or swoole, plus Laravel services can be used in
    fly()
    and
    fly2()
    without closure. The
    fly2()
    has the limited ability to change services in current request, e.g. registering a new event handler for current request.
    fly2()
    is not suggested.

A coroutine starting in a request, can still live when the request ends. What's the effect of following route?
It responds with 'coroutine1; outer1; coroutine2; outer2; outer3',
but it write log 'coroutine1; outer1; coroutine2; outer2; outer3; coroutine2.end; coroutine1.end' ``

// ensure
const LARAVELFLY_COROUTINE = true;` in fly.conf.php

Route::get('/fly', function () {

$a = [];

fly(function () use (&$a) {

$a[] = 'coroutine1';
\co::sleep(2);
$a[] = 'coroutine1.end';
\Log::info(implode('; ', $a));

// Eloquent can be used even if current request has ended.
// $user = new User();
// $user->name = implode('; ',$a);
// $user->save();

});

$a[] = 'outer1';

// go() can use laravel service with closure $log = app('log'); go(function () use (&$a, $log) { $a[] = 'coroutine2'; \co::sleep(1.2); $a[] = 'coroutine2.end'; });

$a[] = 'outer2';

\co::sleep(1);

$a[] = 'outer3';

return implode(';', $a);

}); ```

Similar projects that mix swoole and laravel

The main distinguishing feature of LaravalFly is refactoring Laravel, like what Django 3.0 does.

1. laravel-swoole

It is alse a safe sollution. It has supported Lumen and websocket. Its doc is great and also useful for LaravelFly.

The main difference is that in laravel-swoole user's code will be processed by a new

app
cloned from SwooleTW\Http\Server\Application::$application and laravel-swoole updates related container bindings to the new app. However in LaravelFly, the sandbox is not a new app, but an item in the $corDict of the unique application container.
In LaravelFly, most other objects such as
app
,
event
.... always keep one object in a worker process,
clone
is not used at all by default. LaravelFly makes most of laravel objects keep safe on their own. It's about high cohesion & low coupling and the granularity is at the level of app container or services/objects. For users of laravel-swoole, it's a big challenge to handle the relations of multiple packages and objects which to be booted before any requests. Read Stale Reference.

.

technique work to maintaining relations of cloned objects to avoid Stale Reference
laravel-swoole clone app contaniner and objects to make them safe more work (as app,event...are cloned)
LaravelFly Mode Map refactor most official objects to make them safe on their own few work ( nothing is cloned by default)

In LaravelFly, another benefit of non-cloned objects is allowing some improvements, such as event listeners cache, route middlewares cache.

2. laravel-s

Many great features!

About data pollution? Same technique and problems as laravel-swoole. And neither support coroutine jumping (from one request to another request).

Todo About Improvement

  • [x] Pre-include. Server configs 'preinclude' and 'prefiles'.
  • [x] Server config 'early_laravel'
  • [x] Cache for LaravelFly app config. laravelflypsmap.php or laravelflypssimple.php located bootstrap/cache
  • [x] Cache for Log. Server options 'log_cache'.
  • [x] Watching maintenance mode using swooleeventadd. No need to check file storage/framework/down in every request.
  • [x] Cache for kernel middlewares objects. Kernel::getParsedKernelMiddlewares, only when LARAVELFLY_SERVICES['kernel'] is true.
  • [x] Cache for route middlewares. $cacheByRoute in Router::gatherRouteMiddleware, only useful when all route middleaes are reg on worker.
  • [x] Cache for route middlewares objects. config('laravelfly.singletonroutemiddlewares') and $cacheForObj in Router::gatherRouteMiddleware, avoid creating instances repeatly.
  • [x] Cache for terminateMiddleware objects.
  • [x] Cache for event listeners. $listenersStalbe in LaravelFly\Map\IlluminateBase\Dispatcher
  • [x] Cache for view compiled path. LARAVELFLYSERVICES['view.finder'] or App config 'viewcompile_1'
  • [x] Mysql coroutine. Old code dropped, laravel-s used.
  • [x] db connection pool and redis connection pool. In
    fly()
    or
    fly2()
    , connections to be used would be fetched from pool, not inherit the same connections from request coroutine. code:
    $this->connections[$childId] = [];
