boundary-analyzer 0.4.0

SCOM-based microservice boundary analysis from Jaeger traces

Changelog

v0.4.0 (2026-06-17)

Version-Aware Instrumentation System (new feature)

• NEW: .mba-instrumented marker file written after successful deploy, recording version, mode, and all artifacts created (backups, Dockerfile overrides, compose overrides)
• NEW: check_stale_instrumentation() detects instrumentation from a different MBA version at the start of mba full and automatically cleans up before re-instrumenting
• NEW: cleanup_instrumentation() restores backup files (.mba_bak → original), deletes generated .mba-Dockerfile and .mba-compose-override.yml files
• NEW: On each run, if marker exists with a different version, cleanup runs automatically before discovery

Docker Compose Robustness (bug fixes)

• deploy.py: Added subprocess.TimeoutExpired handler in deploy_docker_compose() — previously an unhandled crash; now produces a clear DOCKER_COMPOSE_FAILED error
• deploy.py: _generate_otel_dockerfile() now logs warnings on all 7 silent failure paths instead of returning (None, None) with no user feedback
• discover.py: Fixed port extraction from Docker Compose YAML. The old p.rsplit(":", 1)[0].rsplit(":", 1)[0] was broken for host_ip:host_port:container_port format (e.g., 127.0.0.1:5000:5000). Now uses a proper _extract_host_port() helper

LLM Chain Improvements (bug fixes + diagnostics)

• instrumentation.py: Added logger.warning() for each reason the LLM returns None: API/Ollama failure, "ERROR:" refusal (with the actual reason), and SyntaxError in generated code. Previously all three were silent
• context.py: Extended _find_main_file() to recognize all entry point names from the Python plugin: run.py, manage.py, wsgi.py, api.py (in addition to existing main.py, app.py, server.py). Also checks subdirectories (app/, src/, application/) for all these names
• context.py: Added "language" key to context dict (value: "python") so the prompt template correctly shows "Language: python" instead of duplicating the framework name
• prompts.py: Fixed "Language:" label to read context.get('language', 'python') instead of context.get('framework', 'unknown')

v0.3.11 (2026-06-17)

Fix Docker daemon detection on Windows

v0.3.10 (2026-06-17)

Docker error messages now accurate

• deploy.py: deploy_docker_compose() and start_jaeger() now distinguish between Docker not installed (DOCKER_NOT_FOUND) and Docker daemon not running (DOCKER_DAEMON_DOWN). Users with Docker installed but Desktop not launched now see: "Docker is installed but the daemon is not running — Start Docker Desktop and wait for it to be ready." instead of the misleading "Docker is required but was not found."

v0.3.9 (2026-06-17)

Bug fixes and robustness improvements

• orchestrator.py: Fixed 'ServiceInfo' object has no attribute 'root_dir' crash when LLM instrumentation tries to read the service path. Now uses entry_points[0].path.parent instead.
• deploy.py: Replaced _docker_available() with 3-functions: _docker_installed(), _docker_daemon_ready(), and retry-based _docker_available() (3 attempts × 3s). Uses docker version --format which is 10× faster than docker info.
• deploy.py: Added Jaeger health check after docker compose up — explicitly waits for port 16686 and verifies /api/services endpoint.
• deploy.py: cleanup_docker_compose() now checks Docker availability first — skips cleanly if the daemon is not responding.
• deploy.py: Reduced timeouts — compose up 300s→120s, compose down 60s→15s, docker check 10s→5s.
• orchestrator.py: _try_cleanup() is now protected against KeyboardInterrupt — clean message instead of traceback.
• cli.py: Top-level KeyboardInterrupt handler — returns exit code 130 with clean message.
• deploy.py: cleanup_docker_compose no longer raises on failure (check=True removed, subprocess.CalledProcessError handled gracefully).
• All 561 tests pass with zero regressions.

v0.3.8 (2026-06-17)

Consolidation — single-service orchestrator

• deploy.py: Python services always use OTLP HTTP/4318 (removed conditional gRPC fallback). Smart Jaeger detection (_jaeger_alive, _docker_container_exists) with 3-case restart logic. New DOCKER_START_FAILED error code.
• discover.py: Service deduplication by (name, deployment). Subdirectory scanning for monorepos (_is_service_dir, _discover_subdirectory_services).
• orchestrator.py: New _llm_instrument_services step called between discovery and deploy, triggered by --llm flag + OPENROUTER_API_KEY. Falls back silently to Dockerfile patching.
• prompts.py: Universal framework-agnostic prompt replaces FastAPI/Flask-only prompt. Python reference appendix (FastAPI, Flask, Django, SQLAlchemy).
• instrumentation.py: Passes structured context dict for richer prompts.
• Tests: All 561 pass with updated env vars and prompt text.

v0.3.7 (2026-06-16)

Bug fixes

• Pipeline crash when no services are flagged suspicious (EmptyDataError on empty CSV). Added size check and try/except in report_builder.py.

v0.3.6 (2026-06-16)

Features

• ENTRYPOINT injected directly into .mba-Dockerfile instead of compose entrypoint override (Docker Compose v5 on Windows clears CMD when entrypoint is set in YAML)
• opentelemetry-distro added as runtime dependency (provides OpenTelemetryConfigurator entry point, needed for SDK config from env vars)
• Windows console encoding fix: sys.stdout.reconfigure(encoding='utf-8') in CLI module

v0.3.5 (2026-06-16)

Features

• Build-time OTel install: generates .mba-Dockerfile with RUN pip install opentelemetry-distro opentelemetry-instrumentation-flask etc. at build time
• Compose override points build.dockerfile to .mba-Dockerfile
• Cleanup of .mba-Dockerfile files after analysis

v1.0.0 (2026-06-11)

Features

• SCOM pipeline : computes Service-COhesion Metric from Jaeger traces (health filtering, endpoint extraction, DB table detection, endpoint-table mapping, threshold analysis, report generation)
• CLI tool : mba / boundary-analyzer commands (run, setup, dashboard, teastore)
• Auto-instrumentation : auto-detects Python microservices (FastAPI, Flask, Django), injects OpenTelemetry, collects traces via Jaeger, runs SCOM analysis
• TeaStore support : Docker Compose deployment with OTel Java agent, traffic generator, trace exporter, full SCOM pipeline
• Dashboard : interactive Dash web UI for SCOM results
• LLM analysis (optional) : AI-powered narrative report via OpenRouter (Qwen), disabled by default

Improvements

• Segment-based health matching (HEALTH_KEYWORDS) instead of fragile endswith — /health/all, /auth/health, /ready/isready, /metrics (via http.target) correctly filtered
• --skip-no-db-services flag to exclude stateless services (proxy, orchestrator, etc.) from SCOM ranking
• run_teastore() function extracted for programmatic access

Bug fixes

• MissingGreenlet in classroom-repository (added selectinload)
• datetime timezone-aware comparison in enrollment-service
• academic_year int→str conversion in enrollment-service
• Scope bug in cleaned_parts variable in CLI cleanup logic
• SQLAlchemy duplicate instrumentation (event listeners only, no SQLAlchemyInstrumentor/AsyncPGInstrumentor)
• [project.scripts] whitespace in pyproject.toml

Tests

• 74 tests total (58 existing + 16 TeaStore)
• TeaStore synthetic fixtures (persistence-service with 5 tables, auth-service without DB)
• 3 test classes : TeaStorePipelineTest, TeaStoreSkipNoDbTest, TeaStoreNoFilterTest

Infrastructure

• CI via GitHub Actions (.github/workflows/ci.yml) — Python 3.11 × 3.12
• mba CLI alias alongside boundary-analyzer
• Version bump to 0.2.0
