status TEXT NOT NULL, - error_message TEXT, - created_at DATETIME DEFAULT CURRENT_TIMESTAMP, - updated_at DATETIME DEFAULT CURRENT_TIMESTAMP -); -``` - -#### Blob Storage -- Direct file storage in `./data/blobs/` -- SHA-256 content addressing -- Efficient for small files and frequently accessed content -- No P2P overhead - immediate availability - -#### Chunk Storage -- Large files split into 2MB pieces in `./data/chunks/` -- BitTorrent-compatible piece structure -- Enables parallel downloads and partial file access -- Each chunk independently content-addressed - -#### Transcoded Storage -- Processed video files stored in `./data/transcoded/` -- Organized by original file hash subdirectories -- H.264/AAC MP4 format for universal web compatibility -- Smart serving prioritizes transcoded versions when available - -### Caching System - -#### LRU Piece Cache -```go -type PieceCache struct { - cache map[string]*CacheEntry - lru *list.List - mutex sync.RWMutex - maxSize int64 - currentSize int64 -} - -type CacheEntry struct { - Key string - Data []byte - Size int64 - AccessTime time.Time - Element *list.Element -} -``` - -**Features**: -- Configurable cache size limits -- Least Recently Used eviction -- Concurrent access with read-write locks -- Cache hit ratio tracking and optimization - -## Video Transcoding System - -### Architecture Overview - -The transcoding system provides automatic video conversion for web compatibility: - -```go -type TranscodingEngine struct { - // Core Components - Transcoder *Transcoder // FFmpeg integration - Manager *Manager // Job coordination - WorkerPool chan Job // Background processing - Database *sql.DB // Status tracking - - // Configuration - ConcurrentJobs int // Parallel workers - WorkDirectory string // Processing workspace - QualityProfiles []Quality // Output formats -} -``` - -### Processing Pipeline - -1. **Upload Detection**: Video files automatically identified during upload -2. **Queue Decision**: Files ≥50MB queued for transcoding with priority based on size -3. **File Reconstruction**: Chunked torrents reassembled into temporary files -4. **FFmpeg Processing**: H.264/AAC conversion with web optimization flags -5. **Smart Serving**: Transcoded versions served when ready, originals as fallback - -### Transcoding Manager - -```go -func (tm *Manager) QueueVideoForTranscoding(fileHash, fileName, filePath string, fileSize int64) { - // Check if already processed - if tm.HasTranscodedVersion(fileHash) { - return - } - - // Analyze file format - needsTranscoding, err := tm.transcoder.NeedsTranscoding(filePath) - if !needsTranscoding { - tm.markAsWebCompatible(fileHash) - return - } - - // Create prioritized job -

} - - tm.transcoder.SubmitJob(job) - tm.markTranscodingQueued(fileHash) -} -``` - -### Smart Priority System - -- **High Priority** (8): Files < 500MB for faster user feedback -- **Medium Priority** (5): Standard processing queue -- **Low Priority** (2): Files > 5GB to prevent resource monopolization - -### Status API Integration - -Users can track transcoding progress via authenticated endpoints: -- `/api/users/me/files/{hash}/transcoding-status` - Real-time status and progress -- Response includes job status, progress percentage, and transcoded file availability - -## P2P Integration & Coordination - -### Unified Peer Discovery - -The P2P coordinator aggregates peers from multiple sources: - -1. **BitTorrent Tracker**: Authoritative peer list from announces -2. **DHT Network**: Distributed peer discovery across the network -3. **WebSeed**: Gateway itself as a reliable seed source - -### Smart Peer Ranking Algorithm - -```go -func (pr *PeerRanker) RankPeers(peers []PeerInfo, clientLocation *Location) []RankedPeer { - var ranked []RankedPeer - - for _, peer := range peers { - score := pr.calculatePeerScore(peer, clientLocation) - ranked = append(ranked, RankedPeer{ - Peer: peer, - Score: score, - Reason: pr.getScoreReason(peer, clientLocation), - }) - } - - // Sort by score (highest first) - sort.Slice(ranked, func(i, j int) bool { - return ranked[i].Score > ranked[j].Score - }) - - return ranked -} -``` - -**Scoring Factors**: -- **Geographic Proximity** (30%): Distance-based scoring -- **Source Reliability** (25%): Tracker > DHT > WebSeed fallback -- **Historical Performance** (20%): Past connection success rates -- **Load Balancing** (15%): Distribute load across available peers -- **Freshness** (10%): Recently seen peers preferred - -### Health Monitoring System - -#### Component Health Scoring -```go -type HealthStatus struct { - IsHealthy bool `json:"is_healthy"` - Score int `json:"score"` // 0-100 - Issues []string `json:"issues"` - LastChecked time.Time `json:"last_checked"` - ResponseTime int64 `json:"response_time"` // milliseconds - Details map[string]interface{} `json:"details"` -} -``` - -**Weighted Health Calculation**: -- WebSeed: 40% (most critical for availability) -- Tracker: 35% (important for peer discovery) -- DHT: 25% (supplemental peer source) - -#### Automatic Alerting -- Health scores below configurable threshold trigger alerts -- Multiple alert mechanisms (logs, callbacks, future integrations) -- Component-specific and overall system health monitoring - -## WebSeed Implementation (BEP-19) - -### Standards Compliance - -The WebSeed implementation follows BEP-19 specification: - -- **URL-based seeding**: BitTorrent clients can fetch pieces via HTTP -- **Range request support**: Efficient partial file downloads -- **Piece boundary alignment**: Proper handling of piece boundaries -- **Error handling**: Appropriate HTTP status codes for BitTorrent clients - -### Advanced Features - -#### Concurrent Request Optimization -```go -type ConcurrentRequestTracker struct { - activeRequests map[string]*RequestInfo - mutex sync.RWMutex - maxConcurrent int -} -``` - -- Prevents duplicate piece loads -- Manages concurrent request limits -- Request deduplication and waiting - -#### Client-Specific Optimizations -```go -func (h *Handler) detectClient(userAgent string) ClientType { - switch { - case strings.Contains(userAgent, "qbittorrent"): - return ClientQBittorrent - case strings.Contains(userAgent, "transmission"): - return ClientTransmission - case strings.Contains(userAgent, "webtorrent"): - return ClientWebTorrent - // ... additional client detection - } -} -``` - -**Per-Client Optimizations**: -- **qBittorrent**: Standard intervals, no special handling needed -- **Transmission**: Prefers shorter announce intervals (≤30 min) -- **WebTorrent**: Short intervals for web compatibility (≤5 min) -- **uTorrent**: Minimum interval enforcement to prevent spam - -## Nostr Integration - -### Content Announcements - -When files are uploaded, they're announced to configured Nostr relays: - -```go -func (g *Gateway) announceToNostr(fileInfo *FileInfo, torrentInfo *TorrentInfo) error { - event := nostr.Event{ - Kind: 2003, // NIP-35 torrent announcement kind - Content: fmt.Sprintf("New torrent: %s", fileInfo.Filename), - CreatedAt: time.Now(), - Tags: []nostr.Tag{ - {"magnet", torrentInfo.MagnetLink}, - {"size", fmt.Sprintf("%d", fileInfo.Size)}, - {"name", fileInfo.Filename}, - {"webseed", g.getWebSeedURL(fileInfo.Hash)}, - }, - } - - return g.nostrClient.PublishEvent(event) -} -``` - -### Decentralized Discovery - -- Content announced to multiple Nostr relays for redundancy -- Other nodes can discover content via Nostr event subscriptions -- Enables fully decentralized content network -- No central authority or single point of failure - -## Performance Optimizations - -### Concurrent Processing - -#### Parallel Piece Loading -```go -func (ws *WebSeedHandler) loadPieces(pieces []PieceRequest) error { - const maxConcurrency = 10 - semaphore := make(chan struct{}, maxConcurrency) - var wg sync.WaitGroup - - for _, piece := range pieces { - wg.Add(1) - go func(p PieceRequest) { - defer wg.Done() - semaphore <- struct{}{} // Acquire - defer func() { <-semaphore }() // Release - - ws.loadSinglePiece(p) - }(piece) - } - - wg.Wait() - return nil -} -``` - -#### Connection Pooling -- HTTP client connection reuse -- Database connection pooling -- BitTorrent connection management -- Resource cleanup and lifecycle management - -## Monitoring & Observability - -### Comprehensive Statistics - -#### System Statistics -```go -type SystemStats struct { - Files struct { - Total int64 `json:"total"` - BlobFiles int64 `json:"blob_files"` - Torrents int64 `json:"torrents"` - TotalSize int64 `json:"total_size"` - } `json:"files"` - - P2P struct { - TrackerPeers int `json:"tracker_peers"` - DHTNodes int `json:"dht_nodes"` - ActiveTorrents int `json:"active_torrents"` -
