Installation
------------

[](#installation)

To install via [Composer](http://getcomposer.org/), use the command below, it will automatically detect the latest version and bind it with `~`.

```
composer require wyrihaximus/react-child-process-pool

```

Pools
-----

[](#pools)

- `Dummy` - Meant for testing, doesn't do anything but complies to it's contract
- `Fixed` - Spawns a given fixed amount of workers
- `Flexible` - Spawns workers as a needed basis, given a minimum and maximum it will spawn within those values

Usage
-----

[](#usage)

This package pools [`wyrihaximus/react-child-process-messenger`](https://github.com/WyriHaximus/reactphp-child-process-messenger), for basic messaging please see that package for details how to use it.

Creating a pool
---------------

[](#creating-a-pool)

This package ships with a set factories, which create different pools. (All the options in the following examples are the default options.)

### Dummy

[](#dummy)

Creates a `Dummy` pool:

```
$loop = EventLoopFactory::create();

Dummy::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) {
  // Now you have a Dummy pool, which does absolutely nothing
});
```

### Fixed

[](#fixed)

Creates a `Fixed` pool:

```
$loop = EventLoopFactory::create();
$options = [
    Options::SIZE => 5,
];
Fixed::createFromClass(ReturnChild::class, $loop, $options)->then(function (PoolInterface $pool) {
    // You now have a pull with 5 always running child processes
});
```

### Flexible

[](#flexible)

Creates a `Flexible` pool:

```
$loop = EventLoopFactory::create();
$options = [
    Options::MIN_SIZE => 0,
    Options::MAX_SIZE => 5,
    Options::TTL      => 0,
];
Flexible::createFromClass(ReturnChild::class, $loop, $options)->then(function (PoolInterface $pool) {
    // You now have a pool that spawns no child processes on start.
    // But when you call rpc a new child process will be started for
    // as long as the pool has work in the queue. With a maximum of five.
});
```

### CpuCoreCountFixed

[](#cpucorecountfixed)

Creates a `Fixed` pool with size set to the number of CPU cores:

```
$loop = EventLoopFactory::create();

CpuCoreCountFlexible::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) {
    // You now have a Fixed pool with a child process assigned to each CPU core.
});
```

### CpuCoreCountFlexible

[](#cpucorecountflexible)

The following example will creates a flexible pool with max size set to the number of CPU cores. Where the `create` method requires you to give it a `React\ChildProcess\Process`. The `createFromClass` lets you pass a classname of a class implementing [`WyriHaximus\React\ChildProcess\Messenger\ChildInterface`](https://github.com/WyriHaximus/reactphp-child-process-messenger/blob/master/src/ChildInterface.php) that will be used as the worker in the client. Take a look at [`WyriHaximus\React\ChildProcess\Messenger\ReturnChild`](https://github.com/WyriHaximus/reactphp-child-process-messenger/blob/master/src/ReturnChild.php) to see how that works.

```
$loop = EventLoopFactory::create();

CpuCoreCountFlexible::createFromClass(ReturnChild::class, $loop)->then(function (PoolInterface $pool) {
    // You now have a Fixed pool with a child process assigned to each CPU core,
    // which, just like the Flexible pool, will only run when there is something
    // in the queue.
});
```
