From 52deda5b469a0ffe0d3554f198c8b506507ce889 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 28 May 2025 02:35:12 +0000 Subject: [PATCH 1/6] feat: Add Redis caching layer for policies This commit introduces a Redis caching layer to the DBAL adapter to improve performance and reduce database load. Features: - Policies loaded via `loadPolicy` and `loadFilteredPolicy` are now cached in Redis. - Configurable Redis connection parameters (host, port, password, database, TTL, prefix). - Automatic cache invalidation for the main policy cache (`all_policies`) when policies are modified. - A `preheatCache()` method to proactively load all policies into Redis. - The adapter remains fully functional if Redis is not configured. Includes: - Updates to `Adapter.php` to integrate caching logic. - Addition of `predis/predis` as a dependency. - Unit tests for the caching functionality in `AdapterWithRedisTest.php`. - Documentation in `README.md` for the new feature. Known limitations: - Cache invalidation for `loadFilteredPolicy` currently only clears the global `all_policies` key, not specific filtered policy keys, to avoid using `KEYS` in production with Predis. --- README.md | 75 +++ composer.json | 3 +- src/Adapter.php | 1153 +++++++++++++++++++------------- tests/AdapterWithRedisTest.php | 249 +++++++ 4 files changed, 1002 insertions(+), 478 deletions(-) create mode 100644 tests/AdapterWithRedisTest.php diff --git a/README.md b/README.md index 45b99b7..fa00108 100644 --- a/README.md +++ b/README.md @@ -62,6 +62,81 @@ if ($e->enforce($sub, $obj, $act) === true) { } ``` +### Redis Caching + +To improve performance and reduce database load, the adapter supports caching policy data using [Redis](https://redis.io/). When enabled, Casbin policies will be fetched from Redis if available, falling back to the database if the cache is empty. + +#### Configuration + +To enable Redis caching, pass a Redis configuration array as the second argument to the `Adapter::newAdapter()` method or the `Adapter` constructor. + +Available Redis configuration options: + +* `host` (string): Hostname or IP address of the Redis server. Default: `'127.0.0.1'`. +* `port` (int): Port number of the Redis server. Default: `6379`. +* `password` (string, nullable): Password for Redis authentication. Default: `null`. +* `database` (int): Redis database index. Default: `0`. +* `ttl` (int): Cache Time-To-Live in seconds. Policies stored in Redis will expire after this duration. Default: `3600` (1 hour). +* `prefix` (string): Prefix for all Redis keys created by this adapter. Default: `'casbin_policies:'`. + +**Example:** + +```php +require_once './vendor/autoload.php'; + +use Casbin\Enforcer; +use CasbinAdapter\DBAL\Adapter as DatabaseAdapter; + +// Database configuration (as before) +$dbConfig = [ + 'driver' => 'pdo_mysql', + 'host' => '127.0.0.1', + 'dbname' => 'test', + 'user' => 'root', + 'password' => '', + 'port' => '3306', +]; + +// Redis configuration +$redisConfig = [ + 'host' => '127.0.0.1', // Optional, defaults to '127.0.0.1' + 'port' => 6379, // Optional, defaults to 6379 + 'password' => null, // Optional, defaults to null + 'database' => 0, // Optional, defaults to 0 + 'ttl' => 7200, // Optional, Cache policies for 2 hours + 'prefix' => 'myapp_casbin:' // Optional, Custom prefix +]; + +// Initialize adapter with both DB and Redis configurations +$adapter = DatabaseAdapter::newAdapter($dbConfig, $redisConfig); + +$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..340d83c 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", diff --git a/src/Adapter.php b/src/Adapter.php index 491ef5b..0266e9d 100644 --- a/src/Adapter.php +++ b/src/Adapter.php @@ -1,477 +1,676 @@ -connection = $connection;

This allows testing the Redis-dependent caching logic of the `Adapter` without requiring a live Redis instance. Key changes include: - Modified `Adapter.php` to allow injection of a `Predis\Client` instance (or a config array). The constructor and `newAdapter` method now accept `mixed $redisOptions`. - Updated `AdapterWithRedisTest.php`: - `setUp()` now creates a mock `PredisClient`. - Test methods (`testLoadPolicyCachesData`, etc.) were updated to configure and expect interactions with this mock client. - `getAdapterWithRedis()` now passes the mock client to the Adapter. Current Test Status for AdapterWithRedisTest.php: - Passing (2/6): - `testAdapterWorksWithoutRedis` - `testLoadPolicyCachesData` - Failing (3/6): - `testCacheInvalidationOnAddPolicy`: Fails due to mock expectation sequence for cache clearing and verification (final `exists` call not reached). - `testCacheInvalidationOnSavePolicy`: Similar to above. - `testPreheatCachePopulatesCache`: Fails as `setex` is not called, likely due to issues with data seeding/retrieval with the in-memory DB for the preheat scenario. - Error (1/6): - `testLoadFilteredPolicyCachesData`: Errors with `Call to undefined method Casbin\Persist\Adapters\Filter::getPredicates()`. This appears to be an external API incompatibility with the current version of `casbin/casbin` or a misconfiguration of the Filter object in the test. Further work may be needed to resolve the failing tests, potentially by refining mock interaction sequences or addressing the in-memory DB behavior for `testPreheatCachePopulatesCache`. The `Filter::getPredicates()` error may require changes to `testLoadFilteredPolicyCachesData` according to the library's API. --- src/Adapter.php | 32 +-- tests/AdapterWithRedisTest.php | 370 ++++++++++++++++++++++++++------- 2 files changed, 317 insertions(+), 85 deletions(-) diff --git a/src/Adapter.php b/src/Adapter.php index 0266e9d..3bbf41a 100644 --- a/src/Adapter.php +++ b/src/Adapter.php @@ -103,10 +103,10 @@ class Adapter implements FilteredAdapter, BatchAdapter, UpdatableAdapter * Adapter constructor. * * @param Connection|array $connection - * @param ?array $redisConfig + * @param array|RedisClient|null $redisOptions Redis configuration array or a Predis\Client instance. * @throws Exception */ - public function __construct(Connection|array $connection, ?array $redisConfig = null) + public function __construct(Connection|array $connection, mixed $redisOptions = null) { if ($connection instanceof Connection) { $this->connection = $connection; @@ -121,13 +121,20 @@ public function __construct(Connection|array $connection, ?array $redisConfig = } } - if (is_array($redisConfig)) { - $this->redisHost = $redisConfig['host'] ?? null; - $this->redisPort = $redisConfig['port'] ?? 6379; - $this->redisPassword = $redisConfig['password'] ?? null; - $this->redisDatabase = $redisConfig['database'] ?? 0; - $this->cacheTTL = $redisConfig['ttl'] ?? 3600; - $this->redisPrefix = $redisConfig['prefix'] ??
