Implement modern storage service with namespace isolation, multipart uploads, and audit logging

[Copilot]

Implements a production-ready object storage service with multi-tenant namespace isolation, resumable uploads for large files, and complete audit trails per the 001-modern-storage-service specification.

Architecture

Storage Layer

• PostgreSQL + TypeORM for metadata (Namespace, Object, UploadSession, AuditEvent entities)
• S3-compatible binary storage (MinIO local, AWS S3 production) via AWS SDK v3
• Pre-signed URLs for time-limited upload/download access

Multi-tenancy

• Namespace-scoped isolation with per-tenant quotas (bytes + object count)
• Automatic usage tracking with increment/decrement on object lifecycle
• Soft delete with deletedAt timestamp for recovery workflows

Resumable Uploads

• S3 multipart API with session tracking in PostgreSQL
• 7-day session expiration with cleanup capability
• SHA-256 checksum validation at S3 layer
• Idempotent initiation (returns existing session if in progress)

API Surface (12 endpoints)

// Namespace management
POST   /api/v1/namespaces
GET    /api/v1/namespaces/:name

// Object operations
POST   /api/v1/objects                          // Returns pre-signed upload URL
GET    /api/v1/objects/:id
POST   /api/v1/objects/:id/signed-url           // Generates download URL (60s-7d)
DELETE /api/v1/objects/:id                      // Soft delete
GET    /api/v1/namespaces/:namespace/objects    // Paginated list with prefix filter

// Multipart uploads
POST   /api/v1/uploads/initiate
PUT    /api/v1/uploads/:sessionId/parts/:partNumber
POST   /api/v1/uploads/:sessionId/complete

// Health
GET    /api/v1/health/live
GET    /api/v1/health/ready                     // DB + S3 connectivity check

Example Usage

# Create namespace
curl -X POST /api/v1/namespaces -d '{
  "name": "org-acme",
  "quotaBytes": 1073741824
}'

# Create object, get pre-signed upload URL
curl -X POST /api/v1/objects -d '{
  "namespace": "org-acme",
  "name": "invoice.pdf",
  "contentType": "application/pdf",
  "sizeBytes": 2048576
}'
# Response includes 15-min pre-signed URL for PUT upload

# Generate download URL
curl -X POST /api/v1/objects/{id}/signed-url -d '{
  "expiresIn": 3600
}'

Configuration

Added database, Redis, and enhanced storage config:

// config.interface.ts
interface DatabaseConfig {
  host: string;
  port: number;
  username: string;
  password: string;
  database: string;
  synchronize: boolean;  // Auto-migrations for dev
}

Docker Compose extended with PostgreSQL and Redis services. Environment template includes all required variables.

Security

• Input validation via class-validator DTOs
• Credential masking in config logging (fixed CodeQL alert)
• Namespace isolation at query level
• Pre-signed URL expiration enforcement

Notes

• Tests not included per spec (no explicit test requirements)
• Cleanup job method exists but not scheduled (Bull queue integration deferred)
• TypeORM synchronize enabled for development (production should use migrations)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• scarf.sh
  • Triggering command: node ./report.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
