Historical deployment analysis — walk git history day by day, deploy per commit, test all endpoints, capture screenshots, restore working fragments.

---

What it does

1. Walk — iterates through git history day by day (configurable range)
2. Deploy — starts the service per commit (docker-compose / uvicorn / none)
3. Scan — detects endpoints via deta scan → OpenAPI → Traefik labels fallback
4. Test — runs testql scenarios or falls back to HTTP probe per endpoint
5. Screenshot — Playwright screenshots per endpoint with retry/timeout
6. Report — generates report.html + results.json per day + timeline index.html
7. Restore — extracts the last working day of an endpoint as an isolated project
8. Dashboard — overlays health% timeline with avg cyclomatic complexity (via toon)

---

Install

pip install resplit

# with Playwright screenshots
pip install "resplit[screenshots]"
playwright install chromium

# development
pip install -e ".[dev]"

---

Quick start

# Dry-run: scan last 30 days without deploy
resplit walk . --days 30 --dry-run

# Full walk with docker-compose
resplit walk . --days 30 --deploy docker-compose

# Walk a specific date range
resplit walk /path/to/repo --from 2024-01-01 --to 2024-04-01

# Restore last working version of an endpoint
resplit restore /api/health .

# Generate timeline report from existing results
resplit report

# Generate CC vs health% dashboard
resplit dashboard --repo .

# Show version
resplit version

Endpoint scanner — 3-level fallback

Level	Source	What it returns
1	deta scan	services → ports → health paths
2	/openapi.json	full endpoint list from OpenAPI spec
3	docker-compose Traefik labels	PathPrefix rules
4	hardcoded fallback	GET /api/health

Tester — 2-level fallback

Level	Condition	Behaviour
1	testql installed + testql_dir set	runs .testql.yaml scenarios
2	fallback	HTTP GET probe per endpoint
