This library provides a Redis mutex implementation for [yiisoft/mutex](https://github.com/yiisoft/mutex).
## Requirements
- PHP 7.4 or higher.
## Installation
The package could be installed with [Composer](https://getcomposer.org):
```shell
composer require yiisoft/mutex-redis
```
## General usage
The package provides two classes implementing `MutexInterface` and `MutexFactoryInterface`
from the [yiisoft/mutex](https://github.com/yiisoft/mutex) package:
```php
/**
* @var \Predis\ClientInterface $client Predis client instance to use.
*/
$mutex = new \Yiisoft\Mutex\Redis\RedisMutex(
'mutex-name',
$client,
60, // Optional. Number of seconds in which the lock will be auto released. Default is `30`.
);
$mutexFactory = new \Yiisoft\Mutex\Redis\RedisMutexFactory(
$client,
60, // Optional. Number of seconds in which the lock will be auto released. Default is `30`.
);
```
For more information about the client instance and connection configuration,
see the documentation of the [predis/predis](https://github.com/predis/predis) package.
There are multiple ways you can use the package. You can execute a callback in a synchronized mode i.e. only a
single instance of the callback is executed at the same time:
```php
$synchronizer = new \Yiisoft\Mutex\Synchronizer($mutexFactory);
$newCount = $synchronizer->execute('critical', function () {
return $counter->increase();
}, 10);
```
Another way is to manually open and close mutex:
```php
$simpleMutex = \Yiisoft\Mutex\SimpleMutex($mutexFactory);
if (!$simpleMutex->acquire('critical', 10)) {
throw new \Yiisoft\Mutex\Exception\MutexLockedException('Unable to acquire the "critical" mutex.');
}
$newCount = $counter->increase();
$simpleMutex->release('critical');
```
It could be done on lower level:
```php
$mutex = $mutexFactory->createAndAcquire('critical', 10);
$newCount = $counter->increase();
$mutex->release();
```
And if you want even more control, you can acquire mutex manually:
```php
$mutex = $mutexFactory->create('critical');
if (!$mutex->acquire(10)) {
throw new \Yiisoft\Mutex\Exception\MutexLockedException('Unable to acquire the "critical" mutex.');
}
$newCount = $counter->increase();
$mutex->release();
```
The `RedisMutex` supports the "wait for a lock for a certain time" functionality. Using the `withRetryDelay()`
method, you can override the number of milliseconds between each try until specified timeout times out:
```php
$mutex = $mutex->withRetryDelay(100);
```
By default, it is 50 milliseconds - it means that we may try to acquire lock up to 20 times per second.
