## Usage
1. Install the package via Composer:
```shell script
composer require illuminated/console-mutex
```
2. Use `Illuminated\Console\WithoutOverlapping` trait:
```php
use Illuminated\Console\WithoutOverlapping;
class ExampleCommand extends Command
{
use WithoutOverlapping;
// ...
}
```
## Strategies
Mutex can prevent overlapping by using various strategies:
- `file` (default)
- `mysql`
- `redis`
- `memcached`
The default `file` strategy is acceptable for small applications, which are deployed on a single server.
If your application is more complex and deployed on several nodes, you should consider using another mutex strategy.
You can change strategy by using the `$mutexStrategy` field:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
protected string $mutexStrategy = 'mysql';
// ...
}
```
Or by using the `setMutexStrategy()` method:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
public function __construct()
{
parent::__construct();
$this->setMutexStrategy('mysql');
}
// ...
}
```
## Advanced
### Set custom timeout
By default, if mutex sees that the command is already running, it will immediately quit.
You can change that behavior by setting a timeout in which mutex can wait for another running command to finish its execution.
You can set the timeout by specifying the `$mutexTimeout` field:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
// In milliseconds
protected ?int $mutexTimeout = 3000;
// ...
}
```
Or by using the `setMutexTimeout()` method:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
public function __construct()
{
parent::__construct();
// In milliseconds
$this->setMutexTimeout(3000);
}
// ...
}
```
Here's how the `$mutexTimeout` field is treated:
- `0` - no waiting (default);
- `{int}` - wait for the given number of milliseconds;
- `null` - wait for the running command to finish its execution;
### Handle multiple commands
Sometimes it might be useful to have a shared mutex for multiple commands.
You can easily achieve that by setting the same mutex name for all of those commands.
You should use the `getMutexName()` method for that:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
public function getMutexName()
{
return 'shared-for-command1-and-command2';
}
// ...
}
```
### Set custom storage folder
If you're using the `file` strategy, mutex files would be stored in the `storage/app` folder.
You can change that by overriding the `getMutexFileStorage()` method:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
public function getMutexFileStorage()
{
return storage_path('my/custom/path');
}
// ...
}
```
## Troubleshooting
### Trait included, but nothing happens?
`WithoutOverlapping` trait overrides the `initialize()` method:
```php
trait WithoutOverlapping
{
protected function initialize(InputInterface $input, OutputInterface $output)
{
$this->initializeMutex();
parent::initialize($input, $output);
}
// ...
}
```
If your command overrides the `initialize()` method too, you have to call the `initializeMutex()` method by yourself:
```php
class ExampleCommand extends Command
{
use WithoutOverlapping;
protected function initialize(InputInterface $input, OutputInterface $output)
{
// You have to call it first
$this->initializeMutex();
// Then goes your custom code
$this->foo = $this->argument('foo');
$this->bar = $this->argument('bar');
$this->baz = $this->argument('baz');
}
// ...
}
```
### Several traits conflict?
If you're using another `illuminated/console-%` package, you'll get the "traits conflict" error.
For example, if you're building a [loggable command](https://github.com/dmitry-ivanov/laravel-console-logger), which doesn't allow overlapping:
```php
class ExampleCommand extends Command
{
use Loggable;
use WithoutOverlapping;
// ...
}
```
You'll get the traits conflict, because both of those traits are overriding the `initialize()` method:
> If two traits insert a method with the same name, a fatal error is produced, if the conflict is not explicitly resolved.
To fix that - override the `initialize()` method and resolve the conflict:
```php
class ExampleCommand extends Command
{
use Loggable;
use WithoutOverlapping;
protected function initialize(InputInterface $input, OutputInterface $output)
{
// Initialize conflicting traits
$this->initializeMutex();
$this->initializeLogging();
}
// ...
}
```
