From 4c9b1063a03a57a08d07735ce3951458687690c9 Mon Sep 17 00:00:00 2001 From: Jonah Gray Date: Thu, 1 Jan 2026 17:18:35 +0000 Subject: [PATCH 01/21] feat(mixins): add Prometheus metrics and Redis cache backends (OMN-1188) Complete stub implementations in MixinMetrics and MixinCaching: MixinMetrics: - Add ProtocolMetricsBackend protocol for backend abstraction - Implement BackendMetricsPrometheus with Gauge, Counter, Histogram support - Implement BackendMetricsInMemory for testing - Add set_metrics_backend(), record_histogram(), push_metrics() methods - Maintain full backward compatibility (in-memory always populated) MixinCaching: - Add ProtocolCacheBackend protocol for L2 cache abstraction - Implement BackendCacheRedis with connection pooling and TTL - Add L1/L2 coordination (read-through, write-through) - Add TTL enforcement for L1 cache - Implement graceful degradation on L2 failures - Maintain full backward compatibility Additional: - Fix misleading "stub models" comment in node_base.py - Add prometheus-client and redis as optional dependencies - Add 148 new tests for backends and mixin enhancements --- poetry.lock | 60 +- pyproject.toml | 11 +-

fix(backends): address PR #301 review feedback (OMN-1188) Security: - Add sanitize_redis_url() to prevent credential leaks in logs - Add _safe_url property for convenient safe logging Exception Handling: - Add 5 cache-specific error codes (321-325) to EnumCoreErrorCode - Wrap L2 cache exceptions in ModelOnexError with structured context - Add _wrap_cache_error() helper for consistent error handling - Add connection pool cleanup in error paths - Add backend connection state validation Prometheus Improvements: - Enhance label mismatch error messages with missing/unexpected details - Add tag tracking for gauges and histograms (not just counters) - Add cardinality warning at configurable threshold - Add push gateway retry logic with exponential backoff - Extract common metric creation logic to reduce duplication Testing: - Add @pytest.mark.timeout(60) to 66 test methods - Add 13 tests for Redis URL sanitization - Add 16 tests for Prometheus improvements Documentation: - Export MixinCaching and BackendMetricsPrometheus from public API - Update usage examples with canonical import paths - Add TTL edge case documentation (ttl=0 behavior) - Extract _cleanup_expired_entries()

[PATCH 05/21] fix(backends): address all PR #301 review issues (OMN-1188) Security: - Add sanitize_error_message() to redact Redis credentials from logs - Mask passwords in connection error messages with *** Exception Handling: - Standardize MixinCaching to use ModelOnexError with error codes - Add specific exception types (ConnectionError, TimeoutError, OSError) - Wrap L2 cache exceptions with appropriate EnumCoreErrorCode values Connection Management: - Add _validate_connection() helper for centralized state validation - Add async context manager support (__aenter__/__aexit__) - Handle edge case where client is None but connected is True Code Quality: - Fix ruff I001 import sorting in protocols/__init__.py - Add explicit handling for ttl<=0 (skip caching) - Document L1/L2 TTL behavior and design decisions - Use canonical import paths (from omnibase_core.enums import) - Add type: ignore comments for pyright compatibility Tests: - Add 11 new tests for
