From 9a82c208e05ff01405269a75d5aa2a95cbeb23b9 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 14 Nov 2025 08:06:14 +0000 Subject: [PATCH 1/7] feat: Enhanced error handling with convenience properties and helper methods This commit significantly improves error handling in the Python SDK by adding: 1. Convenience Properties: - Direct access to error code via e.code (instead of e.parsed_exception.code) - Direct access to error message via e.error_message - Direct access to request ID via e.request_id - Direct access to store ID via e.store_id - Direct access to authorization model ID via e.authorization_model_id 2. Operation Context: - Added operation_name parameter to ApiException and all subclasses - Exceptions now track which operation failed (e.g., "Check", "Write") - operation_name propagated through api_client call stack 3. Helper Methods: - is_validation_error() - Check if error is a validation error - is_not_found_error() - Check if error is a not found error - is_authentication_error() - Check if error is an authentication error - is_authorization_error() - Check if error is an authorization error - is_rate_limit_error() - Check if error is a rate limit error - is_server_error() - Check if error is a server error - is_retryable() - Check if error should be retried 4. Enhanced Error Messages: - __str__ method now includes operation name, error code, message, request ID, store ID, and authorization model ID - More readable and informative error output 5. Testing: - Added comprehensive unit tests (17 test cases) - Added integration tests against real OpenFGA server - Docker Compose setup for integration testing - Test documentation and run script Changes are fully backwards compatible - existing code continues to work. Files modified: - openfga_sdk/exceptions.py: Enhanced ApiException and subclasses - openfga_sdk/api_client.py: Added operation_name parameter propagation - openfga_sdk/sync/api_client.py: Added operation_name parameter propagation Files added: - test/error_handling_improvements_test.py: Unit tests - test/integration_error_handling_test.py: Integration tests - docker-compose.integration-test.yml: Test infrastructure - run_integration_tests.sh: Helper script -

From e15f4304456f30211ca54bc1529922c10331283b Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 14 Nov 2025 08:16:51 +0000 Subject: [PATCH 3/7] feat: Auto-extract operation names from telemetry attributes Previously, operation_name parameter was added but never populated. This commit fixes that by extracting the operation name from telemetry attributes that are already passed to every API call. Changes: - api_client.py: Extract operation_name from telemetry if not provided - sync/api_client.py: Same for synchronous client - Integration tests: Verify operation names are set correctly - New tests: Verify telemetry extraction logic How it works: 1. Generated open_fga_api.py already sets telemetry attributes with method name 2. api_client.__call_api() extracts fga_client_request_method from telemetry 3. Operation name is automatically set on all exceptions 4. No changes needed to generated code Examples: - check() call -> exception.operation_name = "check" - write() call -> exception.operation_name = "write" - batch_check() call -> exception.operation_name = "batch_check" This matches the Java SDK implementation pattern where operation names are automatically tracked without modifying generated API code.
