# Orchard

**Content-Addressable Storage System**

Orchard is a centralized binary artifact storage system that provides content-addressable storage with automatic deduplication, flexible access control, and multi-format package support.

## Tech Stack

- **Backend**: Python 3.12 + FastAPI
- **Frontend**: React 18 + TypeScript + Vite
- **Database**: PostgreSQL 16
- **Object Storage**: MinIO (S3-compatible)
- **Cache**: Redis (for future use)

## Features

### Currently Implemented

- **Content-Addressable Storage** - Artifacts are stored and referenced by their SHA256 hash, ensuring deduplication and data integrity
- **Project/Package/Artifact Hierarchy** - Organized storage structure:
  - **Project** - Top-level organizational container
  - **Package** - Named collection within a project
  - **Artifact** - Specific content instance identified by SHA256
- **Tags** - Alias system for referencing artifacts by human-readable names (e.g., `v1.0.0`, `latest`, `stable`)
- **Package Formats & Platforms** - Packages can be tagged with format (npm, pypi, docker, deb, rpm, etc.) and platform (linux, darwin, windows, etc.)
- **Rich Package Metadata** - Package listings include aggregated stats (tag count, artifact count, total size, latest tag)
- **S3-Compatible Backend** - Uses MinIO (or any S3-compatible storage) for artifact storage
- **PostgreSQL Metadata** - Relational database for metadata, access control, and audit trails
- **REST API** - Full HTTP API for all operations
- **Web UI** - React-based interface for managing artifacts
- **Docker Compose Setup** - Easy local development environment
- **Helm Chart** - Kubernetes deployment with PostgreSQL, MinIO, and Redis subcharts
- **Multipart Upload** - Automatic multipart upload for files larger than 100MB
- **Resumable Uploads** - API for resumable uploads with part-by-part upload support
- **Range Requests** - HTTP range request support for partial downloads
- **Format-Specific Metadata** - Automatic extraction of metadata from package formats:
  - `.deb` - Debian packages (name, version, architecture, maintainer)
  - `.rpm` - RPM packages (name, version, release, architecture)
  - `.tar.gz/.tgz` - Tarballs (name, version from filename)
  - `.whl` - Python wheels (name, version, author)
  - `.jar` - Java JARs (manifest info, Maven coordinates)
  - `.zip` - ZIP files (file count, uncompressed size)

### Resumable Upload (for large files)

For files larger than 100MB, use the resumable upload API:

```bash
# 1. Initialize upload (client must compute SHA256 hash first)
curl -X POST http://localhost:8080/api/v1/project/my-project/releases/upload/init \
  -H "Content-Type: application/json" \
  -d '{
    "expected_hash": "a3f5d8e12b4c67890abcdef1234567890abcdef1234567890abcdef12345678",
    "filename": "large-file.tar.gz",
    "size": 524288000,
    "tag": "v2.0.0"
  }'

# Response: {"upload_id": "abc123", "already_exists": false, "chunk_size": 10485760}

# 2. Upload parts (10MB chunks recommended)
curl -X PUT http://localhost:8080/api/v1/project/my-project/releases/upload/abc123/part/1 \
  --data-binary @chunk1.bin

# 3. Complete the upload
curl -X POST http://localhost:8080/api/v1/project/my-project/releases/upload/abc123/complete \
  -H "Content-Type: application/json" \
  -d '{"tag": "v2.0.0"}'
```

### Download an Artifact

```bash
# By tag
curl -O http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# By artifact ID
curl -O http://localhost:8080/api/v1/project/my-project/releases/+/artifact:a3f5d8e12b4c6789...

# Using the short URL pattern
curl -O http://localhost:8080/project/my-project/releases/+/latest

# Partial download (range request)
curl -H "Range: bytes=0-1023" http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# Check file info without downloading (HEAD request)
curl -I http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0
```

### Create a Tag

```bash
curl -X POST http://localhost:8080/api/v1/project/my-project/releases/tags \
  -H "Content-Type: application/json" \
  -d '{"name": "stable", "artifact_id": "a3f5d8e12b4c6789..."}'
```

### Get Artifact by ID

```bash
curl http://localhost:8080/api/v1/artifact/a3f5d8e12b4c67890abcdef1234567890abcdef1234567890abcdef12345678
