Multiple instances run in parallel (controlled by `WS` env var). Each consumes from priority-ordered Redis streams (`te.1.common`, `te.0.common`), using consumer groups for load distribution. - -Key consequence: task executors import a different code surface than the API server, so always check which process a module is meant for. - -### Backend API (`/api/`) - -- **App factory**: `api/apps/__init__.py` — creates the Quart app, configures auth (`login_required` decorator, JWT + API token + session fallback), and dynamically discovers/registers blueprints -- **Two API coexisting patterns**: - - **RESTful APIs** in `api/apps/restful_apis/` — newer pattern with Pydantic request validation, service layer in `api/apps/services/`, routes registered under `/api/v1` - - **Legacy APIs** in `api/apps/*_app.py` — older pattern using `@validate_request()`, routes registered under `/v1/` - - **SDK APIs** in `api/apps/sdk/` — registered under `/v1/` -- **Services**: `api/db/services/` — business logic wrapping Peewee model operations. `api/apps/services/` — service layer for the RESTful APIs -- **Models**: `api/db/db_models.py` — Peewee ORM models with pooled MySQL/PostgreSQL connections, custom `JSONField`/`ListField` types, retry logic on connection loss - -### Core Processing (`/rag/`) - -- **Document ingestion pipeline**: `rag/flow/pipeline.py` — `Pipeline` (extends `agent.canvas.Graph`) orchestrates the ingestion DAG. Components: File (fetches binary from storage), Parser (dispatches to `deepdoc.parser` based on file type), TokenChunker/TitleChunker (splits into chunks), Tokenizer (computes full-text tokens + embedding vectors), Extractor (LLM-based extraction). Data flows via Pydantic `*FromUpstream` schemas. -- **Document parsing**: `deepdoc/` — PDF parsing (vision-based OCR, layout analysis, table structure recognition) and format-specific parsers (DOCX, XLSX, PPT, Markdown, HTML, images). All parsers normalize to a common structure (list of bbox dicts for PDFs, `{text, doc_type_kwd}` for others). -- **DeepDoc HTTP API service** (`deepdoc/server/`): OSS ONNX models (DLA, OCR, TSR) wrapped with LitServe as a standalone HTTP API on port 8124. The Go parser (`internal/parser/`) calls this service via `DeepDocClient`. Endpoints: `GET /health`, `GET /model`, `POST /predict/dla`, `POST /predict/tsr`, `POST /predict/ocr` (with `operator=det` or `operator=rec` form field). Docker image: `deepdoc_oss:latest`. See `deepdoc/server/README.md` for the full API reference. -- **LLM Integration**: `rag/llm/` — factory pattern with runtime class discovery. `chat_model.py` (30+ providers via OpenAI SDK and LiteLLM wrappers), `embedding_model.py`, `rerank_model.py`, `cv_model.py` (image-to-text), `sequence2txt_model.py` (ASR), `tts_model.py`. Use `LLMBundle` (from `api.db.services.llm_service`) as the unified interface. -- **Graph RAG**: `rag/graphrag/` — multi-phase pipeline: per-document subgraph extraction (LLM or spaCy NER), Leiden community detection, entity resolution, community summarization. Entities/relations/reports are indexed as chunks alongside regular text chunks, differentiated by `knowledge_graph_kwd`. -- **Search**: `rag/nlp/search.py` — `Dealer` class combines vector similarity + BM25 + re-ranking. `KGSearch` extends it for graph-aware retrieval (entity resolution, n-hop enrichment). - -### Agent System (`/agent/`) - -- **Execution engine**: `agent/canvas.py` — `Canvas` (extends `Graph`) executes the DAG. Components are run in topological order via `_run_batch`, each receiving upstream outputs as kwargs. Control-flow components (`Categorize`, `Switch`, `Iteration`, `Loop`) dynamically modify the execution path. -- **Component base**: `agent/component/base.py` — `ComponentBase` with `invoke(**kwargs)` / `invoke_async(**kwargs)` lifecycle. Variable references (`{component_id@output_var}` or `{sys.query}`) are resolved from the canvas graph at runtime. -- **Components**: Modular workflow components in `agent/component/` — Begin, LLM, Agent (tool-calling LLM), Categorize, Switch, Iteration, Loop, Message, Invoke (HTTP), and data manipulation nodes. Auto-discovered by `__init__.py`. -- **Templates**: Pre-built agent workflows as JSON DSL files in `agent/templates/`. Each contains a complete `components` DAG, `path`, and `globals`. -- **Tools**: `agent/tools/` — Retrieval, web search (DuckDuckGo, Google, Tavily, SearXNG), academic search (ArXiv, PubMed, Google Scholar, Wikipedia), code execution, SQL execution, email, GitHub, finance data, translation, weather. Tools implement `ToolBase` (extends `ComponentBase`) and produce OpenAI-compatible function descriptors. -- **Plugins**: `agent/plugin/` — plugin system using `pluginlib` for loading external LLM tool plugins from `embedded_plugins/`. - -### Frontend (`/web/`) - -- React/TypeScript with vitejs framework -- shadcn/ui components (Radix UI primitives + Tailwind CSS) -- `@tanstack/react-query` for server state (cache keys, mutations, invalidation) -- Zustand for local state (primarily agent canvas graph store) -- `react-router` v7 with lazy-loaded pages -- `react-i18next` for i18n (17 languages) -- Axios for HTTP with a layered pattern: endpoint definitions (`utils/api.ts`) → HTTP client (`utils/next-request.ts`) → service layer (`services/`) → query hooks (`hooks/use-*-request.ts`) → components -- `@xyflow/react` for the agent workflow canvas -- `react-hook-form` + `zod` for form validation -- Two API proxy prefixes: `webAPI = '/v1'` (legacy) and `restAPIv1 = '/api/v1'` (RESTful) - -## Common Development Commands - -### Backend Development - -```bash -# Install Python dependencies -uv sync --python 3.13 --all-extras -uv run python3 ragflow_deps/download_deps.py - -# Run once after the first clone to enable local Git hooks -lefthook install - -# Start dependent services -docker compose -f docker/docker-compose-base.yml up -d - -# Run backend (requires services to be running) -source .venv/bin/activate -export PYTHONPATH=$(pwd) -bash docker/launch_backend_service.sh - -# Run tests -uv run pytest - -# Linting -ruff check -ruff format -``` - -### Frontend Development - -```bash -cd web -npm install -npm run dev # Development server -npm run build # Production build -npm run lint # ESLint -npm run test # Jest tests -``` - -### Docker Development - -```bash -# Full stack with Docker (includes deepdoc vision service) -cd docker -docker compose -f docker-compose.yml up -d - -# Check server status -docker logs -f ragflow-server - -# Build the OSS deepdoc vision service standalone -docker build -f docker/Dockerfile_deepdoc_oss -t deepdoc_oss:latest . -docker run -p 8124:8124 deepdoc_oss:latest - -# Rebuild images -docker build --platform linux/amd64 -f Dockerfile -t infiniflow/ragflow:nightly . -``` - -## Key Configuration Files - -- `docker/.env` - Environment variables for Docker deployment -- `docker/service_conf.yaml.template` - Backend service configuration -- `pyproject.toml` - Python dependencies and project configuration -- `web/package.json` - Frontend dependencies and scripts - -## Testing - -- **Python**: pytest with markers (p1/p2/p3 priority levels) -- **Frontend**: Jest with React Testing Library -- **API Tests**: HTTP API and SDK tests in `test/` and `sdk/python/test/` - -## Database Engines - -RAGFlow supports switching between Elasticsearch (default) and Infinity: - -- Set `DOC_ENGINE=infinity` in `docker/.env` to use Infinity -- Requires container restart: `docker compose down -v && docker compose up -d` - -## Account Password Handling (Critical for Login Flow) - -### Password Encryption Pipeline (Browser → Backend → DB Hash) - -The login password verification chain is counterintuitive.

Python uses +// `LLMBundle(tenant_id, embd_id).encode([...])` from +// `rag/flow/tokenizer/tokenizer.py:54-66`; the Go port goes +// through `service.ModelProviderService.GetEmbeddingModel` +// (callers inject the model bundle, see `EncodeFunc` below). +// The component does NOT directly construct a model driver — +// the resolution path depends on tenant/DAO context that lives +// in `internal/service`, and importing `internal/service` from +// `internal/ingestion/component` would invert the dependency +// direction (plan §3 import graph: ingestion → agent/runtime +// only). The injection point is `EncodeFunc` (package-level +// var); production wires it in `main()` (or an analogous +// bootstrap step) and tests inject a stub. When `EncodeFunc` is +// nil the component short-circuits the embedding branch with +// a clear error — the same fail-loud contract the Python side +// enforces via `LLMBundle` constructor. +// +// - BATCHED EMBEDDING (plan §AD-5a): matched. The Python path +// chunks calls by `settings.EMBEDDING_BATCH_SIZE` (default 16) +// and uses an async semaphore (`embed_limiter`).
