From 6ac0d752484f42533349a647f3d66115572a87e4 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 15 Jan 2026 02:35:36 +0000 Subject: [PATCH 1/9] feat: Comprehensive project improvements from analysis Security: - Replace pickle serialization with JSON in cache.py to prevent arbitrary code execution (CWE-502) - Add JSONSerializationError and JSONDeserializationError for better error handling New Features: - Add WebSocket real-time notification support (772 lines) - Implement websocket routes with connection management and event broadcasting Testing: - Add comprehensive webhook handler tests (2161 lines) - Add API performance analyzer tests (328 lines) - Add compliance checker tests (392 lines) - Update test_code_reviewer.py and test_e2e_workflows.py Documentation: - Translate DEPLOYMENT.md from Chinese to English - Translate BEST_PRACTICES.md from Chinese to English - Translate TROUBLESHOOTING.md from Chinese to English Other: - Update container_security.py - Update

00:00:00 2001 From: Claude Date: Thu, 15 Jan 2026 03:00:41 +0000 Subject: [PATCH 4/9] test: Add unit tests for 3 more agents - test_dependency_analyzer.py: Tests for dependency analysis, unused detection, license checks - test_auto_fixer.py: Tests for automated fix generation, rollback plans, common issues - test_config_drift_detector.py: Tests for configuration drift detection across environments Continues improving test coverage for previously untested agents. --- aiops/tests/test_auto_fixer.py | 492 ++++++++++++++++++++++ aiops/tests/test_config_drift_detector.py | 452
