An OPCache preloader for CakePHP.
Reference: https://www.php.net/manual/en/opcache.preloading.php
This package is meant to provide an easy way for CakePHP application developers to generate preload
files. Goals:
- Generate an OPCache preloader with a simple command.
- Allow optionally loading additional resources such as CakePHP plugins, userland app, and
composer packages.
- Provide a simplistic API for writing a custom preloader.
For an alternative approach, checkout [DarkGhostHunter/Preloader](https://github.com/DarkGhostHunter/Preloader).
For an OPCache UI, checkout [amnuts/opcache-gui](https://github.com/amnuts/opcache-gui).
The current release is for CakePHP 5 and PHP 8.1, see previous releases for older versions of CakePHP and PHP.
| Version | Branch | Cake Version | PHP Version |
|---------|----------------------------------------------------------------|--------------|-------------|
| 1.* | [main](https://github.com/cnizzardini/cakephp-preloader) | ^5.0 | ^8.1 |
| 0.* | [v0](https://github.com/cnizzardini/cakephp-preloader/tree/v0) | ^4.2 | ^7.4 |
## Installation
You can install this plugin into your CakePHP application using [composer](https://getcomposer.org).
The recommended way to install composer packages is:
```console
composer require cnizzardini/cakephp-preloader
```
Next, load the plugin:
```shell
bin/cake plugin load CakePreloader
```
Or via manual steps in the CakePHP [plugin documentation](https://book.cakephp.org/5/en/plugins.html#loading-a-plugin).
## Usage
The easiest way to use CakePreloader is via the console command. This command can easily be included as
part of your applications build process.
```console
/srv/app $ bin/cake preloader --help
Generate a preload file
Usage:
cake preloader [options]
Options:
--app Add your applications src directory into the preloader
--help, -h Display this help.
--name The preload file path. (default: ROOT . DS . 'preload.php')
--packages A comma separated list of packages (e.g. vendor-name/package-name) to add to the preloader
--plugins A comma separated list of your plugins to load or `*` to load all plugins/*
--cli Should the preloader file exit when run via the php-cli? (default: true)
--quiet, -q Enable quiet output.
--verbose, -v Enable verbose output.
```
You may also load configurations from a `config/preloader_config.php` file. Please note, **command line arguments take
precedence**. See [assets/preloader_config.php](assets/preloader_config.php) for a sample configuration file. If you
prefer handling configurations another way read the CakePHP documentation on
[loading configuration files](https://book.cakephp.org/5/en/development/configuration.html#loading-configuration-files).
### Examples:
Default loads in CakePHP core files excluding TestSuite, Console, Command, and Shell namespaces. The preload file is
written to `ROOT . DS . 'preload.php'`:
```console
bin/cake preloader
```
Include a list of composer packages:
```console
bin/cake preloader --packages=cakephp/authentication,cakephp/chronos
```
Include your `APP` code:
```console
bin/cake preloader --app
```
Include all your projects plugins:
```console
bin/cake preloader --plugins=*
```
Include a list of your projects plugins:
```console
bin/cake preloader --plugins=MyPlugin,MyOtherPlugin
```
### Before Write Event
You can extend functionality by listening for the `CakePreloader.beforeWrite` event. This is dispatched just before
your preloader file is written.
```php
(\Cake\Event\EventManager::instance())->on('CakePreloader.beforeWrite', function(Event $event){
/** @var Preloader $preloader */
$preloader = $event->getSubject();
$resources = $preloader->getPreloadResources();
// modify resources or whatever...
$preloader->setPreloadResources($resources);
});
```
For more on events, read the CakePHP [Events System](https://book.cakephp.org/5/en/core-libraries/events.html#registering-listeners) documentation.
### Preloader Class
You can customize your OPCache Preloader using the same class used by the console command. Preloader uses a port of
CakePHP 4.x's Filesystem class under the hood.
```php
use CakePreloader\Preloader;
$preloader = new Preloader();
$preloader->loadPath('/required/path/to/files', function (\SplFileInfo $file) {
// optional call back method, return true to add the file to the preloader
return true;
});
// default path is ROOT . DS . 'preload.php'
$preloader->write('/optional/path/to/preloader-file.php');
```
## Performance:
Obviously, these types of benchmarks should be taken with a bit of a gain of salt. I benchmarked this using apache
bench with this project here: https://github.com/mixerapi/demo which is a dockerized REST API
(LEMP stack on alpine + php-fpm 8.0). CakePHP `DEBUG` was set to false.
```ini
extension=intl.so
extension=pdo_mysql.so
extension=sodium
extension=zip.so
zend_extension=opcache.so
[php]
session.auto_start = Off
short_open_tag = Off
opcache.preload_user=root
opcache.preload=/srv/app/preload.php
opcache.interned_strings_buffer = 16
opcache.max_accelerated_files = 20000
opcache.memory_consumption = 256
opcache.enable_cli = 0
opcache.enable = 1
opcache.revalidate_freq = 360
opcache.fast_shutdown = 1
realpath_cache_size = 4096K
realpath_cache_ttl = 600
```
Note: `opcache.preload_user=root` and `opcache.preload=/srv/app/preload.php` were disabled for the no preload run.
| Type | JSON View (no db) | JSON View (db select) |
|---------------------------|------------------------|-------------------------|
| OPCache Only | 892.69 [#/sec] (mean) | 805.29 [#/sec] (mean) |
| OPCache Preload (default) | 1149.08 [#/sec] (mean) | 976.30 [#/sec] (mean) |
This is 28% more requests per second for JSON responses and 21% more requests per second with JSON + simple SQL select
when OPCache Preload is enabled.
## Tests / Analysis
Test Suite:
```console
composer test
```
Test Suite + Static Analysis:
```console
composer check
