Summary

  • Updated utopia-php/pools dependency to include the fix from utopia-php/pools#29 which addresses CLOUD-3K4N (Sentry pool empty errors)
  • The upstream fix adds retry on connection creation failure, diagnostic info (active/idle counts) in error messages, and exception chaining
  • Added tests verifying pool retry behavior and diagnostic error messages through the cache adapter

Test plan

  • testPoolRetriesAfterConnectionCreationFailure — verifies that when the first connection creation fails, the pool retries and cache operations succeed
  • testPoolEmptyErrorIncludesDiagnostics — verifies error messages include pool name, active count, and idle count
  • All existing tests continue to pass (9/9)
  • PHPStan static analysis passes at max level
  • Pint lint check passes

Summary by CodeRabbit

  • Tests

    • Added validation for pool connection resilience and retry behavior after transient connection failures
    • Added verification that pool exhaustion errors include detailed diagnostic information
  • Chores

    • Updated project dependencies and stability configuration to enhance system resilience and reliability

Update pools dependency to include the fix for pool empty resilience
(utopia-php/pools#29). The upstream changes add retry on connection
creation failure, diagnostic info (active/idle counts) in error
messages, and exception chaining. Added tests to verify retry behavior
and diagnostic error messages through the cache adapter.

Walkthrough

The pull request updates the Composer configuration to enable prefer-stable mode and adjusts the minimum-stability to dev, while updating the utopia-php/pools dependency to a development branch version (dev-fix/pool-empty-resilience as 1.1.0). In parallel, two new test methods are added to PoolTest.php to verify pool resilience behavior: one tests retry logic when connection creation fails temporarily, and another validates that pool exhaustion errors include diagnostic information such as pool name and connection status metrics.

41-52: Consider explicitly configuring retry settings for test clarity.

This test relies on the pool's default retry behavior to recover from the transient failure. Adding explicit configuration (like testPoolEmptyErrorIncludesDiagnostics does) would make the test's intent clearer and more resilient to upstream default changes.

         $pool = new UtopiaPool(new Stack(), 'retry-test', 2, function () use ($path, &$callCount) {
             $callCount++;
             if ($callCount === 1) {
                 throw new \Exception('Transient connection failure');
             }

             return new Filesystem($path);
         });
+        $pool->setRetryAttempts(2);
+        $pool->setRetrySleep(0);

         $cache = new Cache(new Pool($pool));

update the test to explicitly set retry configuration on the UtopiaPool

36-39: Consider adding test directory cleanup.

The test directories (pool-retry, pool-diag) are created but not removed after tests complete. While not blocking, adding cleanup in a tearDownAfterClass or individual tearDown would prevent filesystem artifacts from accumulating.
