A storage implementation for the Symfony Lock component, based on the PersistingStoreInterface which uses touch(), file_exists(), or filemtime() on empty files within a dedicated directory.

It supports locking, blocking mode, and auto-release across different applications, provided they use the same directory and the same maximum lifetime.

Lock refresh() requires a TTL that is less than or equal to the maximum lifetime.

Usage

use Oliezekat\SymfonyLockFileTouch\Store;
use Symfony\Component\Lock\Factory;

$store = new Store(/* $locksDirPath, $maxLifeTime */);
$factory = new Factory($store);

$lock = $factory->createLock('test');
if ($lock->acquire()) {
    ...
    $lock->refresh();
}
...
$lock->release();
