Conclusion + +The BitTorrent Gateway represents a comprehensive solution for decentralized content distribution, combining the best aspects of traditional web hosting with peer-to-peer networks. Its modular architecture, intelligent routing, and production-ready features make it suitable for both small-scale deployments and large-scale content distribution networks. + +The system's emphasis on standards compliance, security, and performance ensures reliable operation while maintaining the decentralized principles of the BitTorrent protocol. Through its unified approach to peer discovery, intelligent caching, and comprehensive monitoring, it provides a robust foundation for modern content distribution needs. \ No newline at end of file diff --git a/configs/alert_rules.yml b/configs/alert_rules.yml new file mode 100644 index 0000000..400c834 --- /dev/null +++ b/configs/alert_rules.yml @@ -0,0 +1,100 @@ +groups: + -

⚑ BitTorrent Gateway

+

Comprehensive Unified Content Distribution System

+
+ +
+
+

What This Platform Does

+

The BitTorrent Gateway is a comprehensive unified content distribution system that seamlessly integrates BitTorrent protocol, WebSeed technology, DHT peer discovery, and Nostr announcements. It provides intelligent content distribution by automatically selecting the optimal delivery method:

+ +
+
+
πŸ“„
+
+ Small Files (<100MB) +

Stored as blobs for instant access and immediate availability

+
+
+
β†’
+
+
🧩
+
+ Large Files (β‰₯100MB) +

Automatically chunked into 2MB pieces with torrent + DHT distribution

+
+
+
+
+ +
+

How It Works

+ +
+

πŸ“‘ P2P Coordination

+

The system features a sophisticated P2P coordinator that manages all networking components, providing unified peer discovery, smart peer ranking, load balancing, and health monitoring across tracker, DHT, and WebSeed sources.

+ +

🎯 Built-in BitTorrent Tracker

+
+

Includes a full BitTorrent tracker with advanced features:

+
    +
  • Client Compatibility: Optimized for qBittorrent, Transmission, WebTorrent, Deluge, uTorrent
    • +
  • Abuse Prevention: Advanced detection and rate limiting systems
    • +
  • Geographic Optimization: Proximity-based peer selection for faster transfers
    • +
+
+ +

πŸ”„ WebSeed Implementation (BEP-19)

+
+

Advanced WebSeed features for guaranteed availability:

+
    +
  • LRU Caching: Intelligent piece caching with configurable size limits
    • +
  • Concurrent Optimization: Prevents duplicate loads, manages request limits
    • +
  • Standards Compliant: Full BEP-19 specification support
    • +
+
+ +

🌊 File Processing Pipeline

+
+
+ 1 +
+ Upload & Analysis +

File received, SHA-256 hash calculated, size analysis determines storage strategy

+
+
+
+ 2 +
+ Storage & Distribution +

Small files stored as blobs, large files chunked and torrents created

+
+
+
+ 3 +
+ P2P Announcement +

Content announced to DHT network and Nostr relays for discovery

+
+
+
+ 4 +
+ Immediate Availability +

Content immediately available via WebSeed, P2P peers join over time

Files under 100MB stored as blobs for immediate access. Larger files automatically chunked into 2MB pieces with BitTorrent-compatible structure for parallel transfers.

+
+
+

Advanced P2P Coordination

+

Sophisticated peer ranking algorithm considering geographic proximity (30%), source reliability (25%), and historical performance (20%) for optimal peer selection.

+
+
+

Production-Grade Performance

+

LRU piece caching, concurrent request handling, connection pooling, and comprehensive health monitoring with automatic alerting systems.

+
+
+

Multi-Client Optimization

+

Built-in tracker with client detection and specific optimizations for qBittorrent, Transmission, WebTorrent, and other popular BitTorrent clients.

+# Blossom-BitTorrent Gateway Testing Suite
+
+Comprehensive testing suite for validating the Blossom-BitTorrent Gateway in real-world scenarios.
+
+## Overview
+
+This testing suite provides multiple layers of validation:
+
+1. **Integration Tests**: End-to-end testing with real Blossom servers
+2. **Load Tests**: Performance testing under concurrent load
+3. **Compatibility Tests**: Protocol compliance and format support
+4. **Docker Environment**: Isolated test environment with all dependencies
+
+## Quick Start
+
+### Prerequisites
+
+- Docker and Docker Compose
+- Go 1.21+ (for local testing)
+- curl, jq, bc (for shell scripts)
+
+### Run All Tests
+
+```bash
+# Start the complete test environment
+cd test
+docker-compose --profile orchestrate up --build
+
+# Or run specific test suites
+docker-compose --profile test up --build        # Integration tests
+docker-compose --profile load up --build        # Load tests
+docker-compose --profile compatibility up --build # Compatibility tests
+```
+
+### Quick Smoke Test
+
+```bash
+# Start core services
+docker-compose up -d gateway blossom-server
+
+# Run quick validation
+./integration_test.sh
+```
+
+## Test Suites
+
+### 1. Integration Tests (`integration_test.sh`)
+
+Tests the complete workflow with various file sizes and formats.
+
+**Features:**
+- Real Blossom server integration
+- File upload/download integrity verification
+- BitTorrent torrent generation
+- WebSeed (BEP-19) functionality
+- HLS streaming for video files
+- Nostr NIP-35 event compliance
+
+**Usage:**
+```bash
+# Local execution
+GATEWAY_URL=http://localhost:9876 ./integration_test.sh
+
+# With custom Blossom server
+BLOSSOM_SERVER=https://blossom.example.com ./integration_test.sh
+
+# Docker execution
+docker-compose --profile test run integration-test
+```
+
+**Test Files Generated:**
+- Small file (1KB) - Basic functionality
+- Medium file (10MB) - Chunk handling
+- Large file (100MB) - Performance validation
+- Video files (.mp4, .mkv, .avi, .mov, .webm) - HLS streaming
+
+**Expected Output:**
+```
+πŸš€ Blossom-BitTorrent Gateway Integration Tests
+=============================================
+
+=== Creating Test Files ===
+βœ… Test files created successfully
+
+=== Checking Services ===
+βœ… PASS: Gateway Health Check (1s)
+βœ… PASS: Blossom Server Check (2s)
+
+=== File Upload and Validation Tests ===
+  βœ… PASS: Upload small_file.txt (3s) - Hash: abc123..., Speed: 0.33MB/s
+  βœ… PASS: Download small_file.txt (1s) - Integrity verified, Speed: 1.00MB/s
+  βœ… PASS: Torrent small_file.txt (2s) - Generated torrent file (456 bytes)
+  βœ… PASS: WebSeed small_file.txt (1s) - Full file access successful
+...
+```
+
+### 2. Load Tests (`load_test.go`)
+
+Stress testing with configurable concurrent users and duration.
+
+**Features:**
+- Concurrent file uploads
+- Performance metrics collection
+- Response time percentiles (P95, P99)
+- Throughput measurement
+- Resource usage monitoring
+- Bottleneck identification
+
+**Usage:**
+```bash
+# Local execution
+go run load_test.go
+
+# With custom parameters
+GATEWAY_URL=http://localhost:9876 \
+CONCURRENT_USERS=50 \
+TEST_DURATION=10m \
+FILE_SIZE=5242880 \
+go run load_test.go
+
+# Docker execution
+docker-compose --profile load run load-test
+```

+```bash
+# Run all test suites
+TEST_SUITE=all docker-compose --profile orchestrate up
+
+# Run specific suite
+TEST_SUITE=integration docker-compose --profile orchestrate up
+TEST_SUITE=load docker-compose --profile orchestrate up
+TEST_SUITE=compatibility docker-compose --profile orchestrate up
+
+# Quick smoke tests
+TEST_SUITE=quick docker-compose --profile orchestrate up
+```
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `GATEWAY_URL` | Gateway base URL | `http://localhost:9876` |
+| `BLOSSOM_SERVER` | Blossom server URL | `http://localhost:3000` |
+| `NOSTR_RELAYS` | Comma-separated Nostr relays | `wss://relay.damus.io` |
+| `CONCURRENT_USERS` | Load test concurrent users | `10` |
+| `TEST_DURATION` | Load test duration | `2m` |
+| `FILE_SIZE` | Test file size in bytes | `1048576` (1MB) |
+| `PARALLEL_TESTS` | Run tests in parallel | `true` |
+
+### Service Configuration
+
+#### Blossom Server (`blossom-config.json`)
+```json
+{
+  "port": 3000,
+  "storage": {
+    "type": "filesystem",
+    "path": "/data/blobs"
+  },
+  "limits": {
+    "max_blob_size": 104857600,
+    "max_total_size": 10737418240
+  }
+}
+```
+
+#### Nostr Relay (`nostr-relay-config.toml`)
+```toml
+[network]
+port = 7777
+address = "0.0.0.0"
+
+[limits]
+messages_per_sec = 100
+max_message_length = 128000
+max_subscriptions = 20
+```
+
+## Monitoring
+
+Optional monitoring stack with Prometheus and Grafana:
+
+```bash
+# Start monitoring
+docker-compose --profile monitoring up -d
+
+# Access interfaces
+open http://localhost:9090  # Prometheus
+open http://localhost:3001  # Grafana (admin/admin123)
+```
+
+**Metrics Collected:**
+- Request rates and response times
+- Upload/download throughput
+- Error rates and status codes
+- Resource utilization (CPU, memory)
+- Active connections and goroutines
+
+## Test Results
+
+All tests generate detailed JSON results and logs:
+
+**File Locations:**
+- Integration: `./test_results/integration_test_results_YYYYMMDD_HHMMSS.json`
+- Load: `./test_results/load_test_results_YYYYMMDD_HHMMSS.json`
+- Compatibility: `./test_results/compatibility_test_results_YYYYMMDD_HHMMSS.json`
+- Orchestrator: `./test_results/test_orchestrator_report.json`
+
+**Result Structure:**
+```json
+{
+  "test_run": {
+    "timestamp": "2024-01-15T10:30:00Z",
+    "gateway_url": "http://localhost:9876",
+    "environment": {...}
+  },
+  "results": {
+    "total": 45,
+    "passed": 43,
+    "failed": 2,
+    "success_rate": 95.6
+  },
+  "performance_metrics": {...}
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Port Conflicts**
+   ```bash
+   # Check for conflicting processes
+   lsof -i :9876 -i :3000 -i :7777
+   
+   # Use different ports
+   docker-compose -f docker-compose.yml -f docker-compose.override.yml up
+   ```
+
+2. **Service Startup Failures**
+   ```bash
+   # Check service logs
+   docker-compose logs gateway
+   docker-compose logs blossom-server
+   
+   # Restart specific service
+   docker-compose restart gateway
+   ```
+
+3. **Test File Generation Issues**
+   ```bash
+   # Generate test files manually
+   docker-compose --profile setup run test-file-generator
+   
+   # Check disk space
+   df -h
+   ```
+
+4. **Network Connectivity**
+   ```bash
+   # Test internal connectivity
+   docker-compose exec gateway ping blossom-server
+   
+   # Check exposed ports
+   docker-compose ps
+   ```
+
+### Debug Mode
+
+Enable verbose logging:
+
+```bash
+# Docker Compose with debug logs
+docker-compose --verbose up
+
+# Individual service logs
+docker-compose logs -f gateway
+
+# Test script debug
+DEBUG=1 ./integration_test.sh
+```
+
+### Performance Tuning
+
+For large-scale testing:
+
+```bash
+# Increase resource limits
+echo '{"default-ulimits": {"nofile": {"soft": 65536, "hard": 65536}}}' > /etc/docker/daemon.json
+sudo systemctl restart docker
+
+# Use faster storage
+docker-compose -f docker-compose.yml -f docker-compose.fast-storage.yml up
+```
+
+## Continuous Integration
+
+### GitHub Actions Integration
+
+```yaml
+name: Gateway Tests
+on: [push, pull_request]
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Run Tests
+        run: |
+          cd test
+          docker-compose --profile orchestrate up --abort-on-container-exit
+```
+
+### Custom CI Pipeline
+
+```bash
+#!/bin/bash
+set -e
+
+# Start test environment
+docker-compose up -d
+
+# Wait for services
+./wait-for-services.sh
+
+# Run test suites
+./integration_test.sh
+go run load_test.go
+go run compatibility_test.go
+
+# Collect results
+tar -czf test_results_$(date +%Y%m%d_%H%M%S).tar.gz test_results/
+```
+
+## Contributing
+
+### Adding New Tests
+
+1. **Integration Tests**: Add test cases to `integration_test.sh`
+2. **Load Tests**: Modify parameters in `load_test.go`
+3. **Compatibility Tests**: Add format support in `compatibility_test.go`
+4. **Docker Services**: Update `docker-compose.yml`
+
+### Test Development Guidelines
+
+- Include clear pass/fail criteria
+- Provide detailed error messages
+- Generate structured JSON results
+- Add comprehensive logging
+- Validate cleanup procedures
