-## 🏗️ Infrastructure Architecture - -### Correlation ID Assignment Rules - -Correlation IDs enable distributed tracing across infrastructure components: - -1. **Always propagate**: Pass `correlation_id` from incoming requests to error context -2. **Auto-generation**: If no `correlation_id` exists, generate one using `uuid4()` -3. **UUID format**: Use UUID4 format for all new correlation IDs -4. **Include everywhere**: Add `correlation_id` in all error context for tracing - -```python -from uuid import UUID, uuid4 - -# Pattern 1: Propagate from request -correlation_id = request.correlation_id or uuid4() - -# Pattern 2: Generate if not available -context = ModelInfraErrorContext( - transport_type=EnumInfraTransportType.KAFKA, - operation="produce_message", - correlation_id=correlation_id, -) - -# Pattern 3: Extract from incoming event -correlation_id = event.metadata.get("correlation_id") -if isinstance(correlation_id, str): - correlation_id = UUID(correlation_id) -``` - -### Error Sanitization Guidelines - -**NEVER include in error messages or context**: -- Passwords, API keys, tokens, secrets -- Full connection strings with credentials -- PII (names, emails, SSNs, phone numbers) -- Internal IP addresses (in production logs) -- Private keys or certificates -- Session tokens or cookies - -**SAFE to include**: -- Service names (e.g., "postgresql", "kafka") -- Operation names (e.g., "connect", "query", "authenticate") -- Correlation IDs (always include for tracing) -- Error codes (e.g., `EnumCoreErrorCode.DATABASE_CONNECTION_ERROR`) -- Sanitized hostnames (e.g., "db.example.com") -- Port numbers -- Retry counts and timeout values -- Resource identifiers (non-sensitive) - -```python -# BAD - Exposes credentials -raise InfraConnectionError( - f"Failed to connect with password={password}", # NEVER DO THIS - context=context, -) - -# GOOD - Sanitized error message -raise InfraConnectionError( -

-### Error Recovery Patterns - -Infrastructure errors often require recovery strategies. Here are common patterns for handling infrastructure failures: - -#### Retry with Exponential Backoff (Connection Errors) - -Use exponential backoff for transient connection failures. This pattern is ideal for `InfraConnectionError` when services are temporarily unavailable: - -```python -import time -from uuid import uuid4 -from omnibase_infra.errors import InfraConnectionError, ModelInfraErrorContext -from omnibase_infra.enums import EnumInfraTransportType - -def connect_with_retry(host: str, port: int, max_retries: int = 3) -> Connection: - """Connect to database with exponential backoff retry strategy.""" - correlation_id = uuid4() - context = ModelInfraErrorContext( - transport_type=EnumInfraTransportType.DATABASE, - operation="connect", - target_name="postgresql-primary", - correlation_id=correlation_id, - ) - - for attempt in range(max_retries): - try: - return create_connection(host, port) - except ConnectionError as e: - if attempt == max_retries - 1: - raise InfraConnectionError( - f"Failed to connect after {max_retries} attempts", - context=context, - host=host, - port=port, - retry_count=attempt + 1, - ) from e - - # Exponential backoff: 1s, 2s, 4s - wait_time = 2 ** attempt - time.sleep(wait_time) +raise InfraConnectionError("Failed to connect", context=context) from e ``` -#### Circuit Breaker Pattern (Unavailable Services) - -Use the circuit breaker pattern for `InfraUnavailableError` to prevent cascading failures and give services time to recover: - -```python -import time -from enum import Enum -from omnibase_infra.errors import InfraUnavailableError, ModelInfraErrorContext -from omnibase_infra.enums import EnumInfraTransportType - -class CircuitState(str, Enum): - """Circuit breaker state machine.""" - CLOSED = "closed" # Normal operation - OPEN = "open" # Blocking requests - HALF_OPEN = "half_open" # Testing recovery - -class CircuitBreaker: - """Prevents cascading failures with configurable circuit breaker.""" - - def __init__( - self, - failure_threshold: int = 5, - reset_timeout: float = 30.0, - context: ModelInfraErrorContext = None, - ): - self.failure_count = 0 - self.threshold = failure_threshold - self.reset_timeout = reset_timeout - self.last_failure_time = 0.0 - self.state = CircuitState.CLOSED - self.context = context or ModelInfraErrorContext( - transport_type=EnumInfraTransportType.HTTP, - operation="circuit_breaker", - target_name="service", - ) - - def call(self, func, *args, **kwargs): - """Execute function through circuit breaker protection.""" - if self.state == CircuitState.OPEN: - # Check if reset timeout has passed - if time.time() - self.last_failure_time > self.reset_timeout: - self.state = CircuitState.HALF_OPEN - self.failure_count = 0 - else: - raise InfraUnavailableError( - "Circuit breaker is open - service temporarily unavailable", - context=self.context, - circuit_state=self.state.value, - retry_after_seconds=int( - self.reset_timeout - (time.time() - self.last_failure_time) - ), - ) - - try: - result = func(*args, **kwargs) - - # Success - reset circuit - if self.state == CircuitState.HALF_OPEN: - self.state = CircuitState.CLOSED - self.failure_count = 0 - return result - - except Exception as e: - self.failure_count += 1 - self.last_failure_time = time.time() - - # Open circuit if threshold exceeded - if self.failure_count >= self.threshold: - self.state = CircuitState.OPEN - - raise +### Error Hierarchy ``` - -#### Graceful Degradation (Timeout Errors) - -Use graceful degradation for `InfraTimeoutError` to maintain service availability with reduced functionality: - -```python -from collections.abc import Callable -from types import FrameType -from typing import TypeVar -from uuid import UUID - -from pydantic import BaseModel - -from omnibase_infra.errors import InfraTimeoutError, ModelInfraErrorContext -from omnibase_infra.enums import EnumInfraTransportType -

raise TimeoutError("Operation exceeded timeout") - - # Set timeout handler - signal.signal(signal.SIGALRM, timeout_handler) - signal.alarm(int(timeout_seconds)) - - try: - # Try primary data source - return ModelFetchResult( - data=primary_func(), - source="primary", - degraded=False, - ) - - except TimeoutError: - # Log timeout but continue with fallback - context_with_fallback = ModelInfraErrorContext( - transport_type=context.transport_type, - operation=context.operation, - target_name=context.target_name, - correlation_id=context.correlation_id, - ) - - try: - # Use fallback source (cache, secondary database, etc.) -

"Primary timeout and fallback failed", - context=context_with_fallback, - timeout_seconds=timeout_seconds, - ) from fallback_error - - finally: - signal.alarm(0) # Cancel alarm -``` - -#### Credential Refresh (Authentication Errors) - -Use credential refresh for `InfraAuthenticationError` to handle token expiration gracefully: - -```python -from omnibase_infra.errors import InfraAuthenticationError, ModelInfraErrorContext -from omnibase_infra.enums import EnumInfraTransportType -import time - -class CredentialRefreshManager: - """Manages credential refresh with automatic token renewal.""" - - def __init__( - self, - credential_provider, - refresh_threshold_seconds: float = 300.0, - ): - self.provider = credential_provider -
