Helmut Januschka b90bfd9f46 Add Go implementation of VibeTunnel server (#16) ... * Add Linux implementation of VibeTunnel This commit introduces a complete Linux port of VibeTunnel, providing feature parity with the macOS version. The implementation includes: - Full Go-based server with identical REST API and WebSocket endpoints - Terminal session management using PTY (pseudo-terminal) handling - Asciinema recording format for session playback - Compatible CLI interface matching the macOS `vt` command - Support for all VibeTunnel features: password protection, network modes, ngrok integration - Comprehensive build system with Makefile supporting various installation methods - Systemd service integration for running as a system daemon The Linux version maintains 100% compatibility with the existing web UI and can be used as a drop-in replacement for the macOS app on Linux systems. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Add comprehensive ngrok integration to Linux VibeTunnel Implements full ngrok tunnel support for the Go/Linux version to match the macOS Swift implementation, enabling secure public access to local VibeTunnel instances. - **ngrok Service**: Complete lifecycle management with status tracking - **HTTP API**: RESTful endpoints matching macOS version - **CLI Support**: Command-line ngrok flags and integration - **Auto-forwarding**: Built-in HTTP request forwarding to local server - `POST /api/ngrok/start` - Start tunnel with auth token - `POST /api/ngrok/stop` - Stop active tunnel - `GET /api/ngrok/status` - Get current tunnel status - Uses `golang.ngrok.com/ngrok` SDK for native Go integration - Thread-safe service with mutex protection - Comprehensive error handling and logging - Real-time status updates (disconnected/connecting/connected/error) - Proper context cancellation for graceful shutdown ```bash vibetunnel --serve --ngrok --ngrok-token "your_token" vibetunnel --serve --port 4030 --ngrok --ngrok-token "your_token" ``` - Added golang.ngrok.com/ngrok v1.13.0 - Updated web packages (security fixes for puppeteer) Maintains full API compatibility with macOS VibeTunnel for seamless cross-platform operation and consistent web frontend integration. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * up * Fix SSE streaming performance with byte-based approach Addresses @badlogic's review feedback to prevent performance issues with line-based file reading in processNewContent(). ## Changes Made ### Performance Fix - **Byte-based seeking**: Replace line counting with file position tracking - **Efficient reads**: Only read new content since last position using file.Seek() - **Memory optimization**: Avoid reading entire file on each update - **Incomplete line handling**: Properly handle partial lines at file end ### Technical Details - Changed lastLineCount *int → seenBytes *int64 - Use file.Seek(seenBytes, 0) to jump to last read position - Read only new content with currentSize - seenBytes - Handle incomplete lines by adjusting seek position - Maintains same functionality with better performance ### Benefits - **Scalability**: No longer reads entire file for each update - **Performance**: O(new_content) instead of O(total_content) - **Memory**: Constant memory usage regardless of file size - **Reliability**: Handles concurrent writes and partial lines correctly This prevents the SSE streaming from exploding in our faces as @badlogic warned, especially for long-running sessions with large output files. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Optimize streaming performance to reduce 1+ second delays Implements multiple optimizations to address user-reported 1+ second delay between typing and stream rendering: ## PTY Reading Optimizations - **Reduced sleep times**: 100ms → 1ms for EOF checks - **Faster polling**: 10ms → 1ms for zero-byte reads - **FIFO optimization**: 1s → 100ms for stdin EOF polling ## UTF-8 Buffering Improvements - **Timeout-based flushing**: 5ms timer for incomplete UTF-8 sequences - **Real-time streaming**: Don't wait for complete sequences in interactive mode - **Smart buffering**: Balance correctness with responsiveness ## File I/O Optimizations - **Immediate sync**: Call file.Sync() after each write for instant fsnotify - **Reduced SSE timeout**: 1s → 100ms for session alive checks - **Better responsiveness**: Ensure file changes trigger immediately ## Technical Changes - Added StreamWriter.scheduleFlush() with 5ms timeout - Enhanced writeEvent() with conditional file syncing - Optimized PTY read/write loop timing - Improved SSE streaming frequency These changes target the main bottlenecks identified in the PTY → file → fsnotify → SSE → browser pipeline. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix critical stdin polling delay causing 1+ second input lag - Reduced FIFO EOF polling from 100ms to 1ms - Reduced EAGAIN polling from 1ms to 100µs - Added immediate continue after successful writes - This eliminates the major input delay bottleneck 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix critical performance issues causing resource leaks and CPU burns Performance optimizations based on code review feedback: 1. **Fix SSE goroutine leaks**: - Added client disconnect detection to SSE streams - Propagate write errors to detect when clients close connections - Prevents memory leaks from abandoned streaming goroutines 2. **Fix PTY busy-loop CPU burn**: - Increased sleep from 1ms to 10ms in idle scenarios - Reduces CPU wake-ups from 1000/s to 100/s (10x improvement) - Significantly reduces CPU usage when PTY is idle 3. **Multi-stream disconnect detection**: - Added error checking to multi-stream write operations - Prevents goroutine leaks in multi-session streaming These fixes address the "thing of the things" - performance\! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Standardize session creation API response format to match Rust server Changes: - Updated Go server session creation response to include success/message/error fields - Now returns: {"success": true, "message": "Session created successfully", "error": null, "sessionId": "..."} - Maintains backward compatibility with existing sessionId field - Go server already supported both input formats (cmdline/command, cwd/workingDir) This achieves protocol compatibility between Go and Rust implementations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix delete endpoint to return 200 OK with JSON response - Changed handleKillSession to return 200 OK instead of 204 No Content - Added JSON response with success/message fields for consistency - Fixes benchmark tool compatibility expecting 200 response 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Update Go server API to match Rust format exactly - Use 'command' array instead of 'cmdline' - Use 'workingDir' instead of 'cwd' - Remove compatibility shims for cleaner API - Better error messages matching Rust server 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Major performance optimizations for Go server - Remove 100ms artificial delay in session creation (-100ms per session) - Optimize PTY I/O handling with reduced polling intervals - Implement persistent stdin pipes to avoid repeated open/close - Batch file sync operations to reduce I/O overhead (5ms batching) - Remove blocking status updates from API handlers - Increase SSE session check interval from 100ms to 1s Target: Match Rust performance (60ms avg latency, 16+ ops/sec) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Fix O_NONBLOCK compilation issue * Add comprehensive TLS/HTTPS support with Caddy integration Features: - Optional TLS support via CLI flags (defaults to HTTP like Rust) - Self-signed certificate generation for localhost development - Let's Encrypt automatic certificate management for domains - Custom certificate support for production environments -
