When enabled, Casbin policies will be fetched from Redis if available, falling back to the database if the cache is empty. + +To enable Redis caching, provide a Redis configuration array as the second argument when initializing the adapter. The first argument remains your Doctrine DBAL connection (either a parameters array or a `Connection` object). + +**Redis Configuration Options:** + +* `host` (string): Hostname or IP address of the Redis server. Default: `'127.0.0.1'`. +* `port` (int): Port number of the Redis server. Default: `6379`. +* `password` (string, nullable): Password for Redis authentication. Default: `null`. +* `database` (int): Redis database index. Default: `0`. +* `ttl` (int): Cache Time-To-Live in seconds. Policies stored in Redis will expire after this duration. Default: `3600` (1 hour). +* `prefix` (string): Prefix for all Redis keys created by this adapter. Default: `'casbin_policies:'`. + +**Example:** + +```php +require_once './vendor/autoload.php'; + +use Casbin\Enforcer; +use CasbinAdapter\DBAL\Adapter as DatabaseAdapter; +use Doctrine\DBAL\DriverManager; // Required if creating a new connection object + +// Database connection parameters (can be an array or a Connection object) +$dbConnectionParams = [ + 'driver' => 'pdo_mysql', + 'host' => '127.0.0.1', + 'dbname' => 'casbin_db', + 'user' => 'root', + 'password' => '', + 'port' => '3306', +]; +// Example with DBAL connection object: +// $dbalConnection = DriverManager::getConnection($dbConnectionParams); + +// Redis configuration +$redisConfig = [ + 'host' => '127.0.0.1', // Optional, defaults to '127.0.0.1' + 'port' => 6379, // Optional, defaults to 6379 + 'password' => null, // Optional, defaults to null + 'database' => 0, // Optional, defaults to 0 + 'ttl' => 7200, // Optional, Cache policies for 2 hours (default is 3600) + 'prefix' => 'myapp_casbin:' // Optional, Custom prefix (default is 'casbin_policies:') +]; + +// Initialize adapter with DB parameters array and Redis configuration +$adapter = DatabaseAdapter::newAdapter($dbConnectionParams, $redisConfig); +// Or, using a DBAL Connection object: +// $adapter = DatabaseAdapter::newAdapter($dbalConnection, $redisConfig); +// Alternatively, using the constructor: +// $adapter = new DatabaseAdapter($dbConnectionParams, $redisConfig); + +$e = new Enforcer('path/to/model.conf', $adapter); + +// ... rest of your Casbin usage +``` + +#### Cache Preheating + +The adapter provides a `preheatCache()` method to proactively load all policies from the database and store them in the Redis cache. This can be useful during application startup or as part of a scheduled task to ensure the cache is warm, reducing latency on initial policy checks. + +**Example:** + +```php +if ($adapter->preheatCache()) { + // Cache preheating was successful + echo "Casbin policy cache preheated successfully.\n"; +} else { + // Cache preheating failed (e.g., Redis not available or DB error) + echo "Casbin policy cache preheating failed.\n"; +} +``` + +#### Cache Invalidation + +The cache is designed to be automatically invalidated when policy-modifying methods are called on the adapter (e.g., `addPolicy()`, `removePolicy()`, `savePolicy()`, etc.). Currently, this primarily clears the cache key for all policies (`{$prefix}all_policies`). + +**Important Note:** The automatic invalidation for *filtered policies* (policies loaded via `loadFilteredPolicy()`) is limited. Due to the way `predis/predis` client works and to avoid using performance-detrimental commands like `KEYS *` in production environments, the adapter does not automatically delete cache entries for specific filters by pattern. If you rely heavily on `loadFilteredPolicy` and make frequent policy changes, consider a lower TTL for your Redis cache or implement a more sophisticated cache invalidation strategy for filtered results outside of this adapter if needed. The main `{$prefix}all_policies` cache is cleared on any policy change, which means subsequent calls to `loadPolicy()` will refresh from the database and update this general cache. + ### Getting Help - [php-casbin](https://github.com/php-casbin/php-casbin) diff --git a/composer.json b/composer.json index 36bf3d0..6c8d4bf 100644 --- a/composer.json +++ b/composer.json @@ -20,7 +20,8 @@ "require": { "php": ">=8.0", "casbin/casbin": "^4.0", - "doctrine/dbal": "^3.9|^4.0" + "doctrine/dbal": "^3.9|^4.0", + "predis/predis": "^2.0" }, "require-dev": { "phpunit/phpunit": "~9.0", @@ -36,4 +37,4 @@ "CasbinAdapter\\DBAL\\Tests\\": "tests/" } } -} \ No newline at end of file +} diff --git a/src/Adapter.php b/src/Adapter.php index 491ef5b..3bbf41a 100644 --- a/src/Adapter.php +++ b/src/Adapter.php @@ -1,477 +1,684 @@ -connection = $connection;
