This library provides an Oracle mutex implementation for [yiisoft/mutex](https://github.com/yiisoft/mutex).
## Requirements
- PHP 7.4 or higher.
- `PDO` PHP extension.
## Installation
The package could be installed with [Composer](https://getcomposer.org):
```shell
composer require yiisoft/mutex-pdo-oracle
```
## General usage
The package provides two classes implementing `MutexInterface` and `MutexFactoryInterface`
from the [yiisoft/mutex](https://github.com/yiisoft/mutex) package:
```php
use Yiisoft\Mutex\Oracle\OracleMutex;
use Yiisoft\Mutex\Oracle\OracleMutexFactory;
/**
* @var \PDO $connection Configured for Oracle.
*/
$mutex = new OracleMutex(
'mutex-name',
$connection,
OracleMutex::MODE_X, // Optional. Lock mode to be used. Default is `OracleMutex::MODE_X`.
false, // Optional. Whether to release lock on commit. Default is `false`.
);
$mutexFactory = new OracleMutexFactory(
$connection,
OracleMutex::MODE_X, // Optional. Lock mode to be used. Default is `OracleMutex::MODE_X`.
false, // Optional. Whether to release lock on commit. Default is `false`.
);
```
Read more about the "lock mode" and "release lock on commit" options in the
[Oracle documentation](https://docs.oracle.com/en/database/oracle/oracle-database/21/arpls/DBMS_LOCK.html).
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 `OracleMutex` 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.
