Rush Sync Server

NOTE: Version 0.2.2 on crates.io has a critical bug in language file loading (*.json not embedded correctly). Please use version 0.3.6+ for a stable release!

Rush Sync Server is a professional web server orchestration platform written in Rust. It combines a robust Terminal UI (TUI) with internationalization, theming, a modular command system, production HTTPS/TLS, reverse proxy, WebSocket-based hot reload, and a live dashboard.

NEW in v0.3.6: Anti-Flicker color mapping for display labels, hardened terminal lifecycle (TerminalManager + safe restart flow), unified widget/input system with viewported rendering and blinking cursor, multi-terminal cursor coloring (Apple Terminal/iTerm/tmux), minimal dashboard CSS reset, viewport safety guards, and extended logging/i18n.

---

Project Vision

Rush Sync Server development phases:

• Phase 0 ✅: Terminal UI foundation with command system
• Phase 1 ✅ COMPLETE: Production-ready server orchestration with enterprise features
• Phase 2: Advanced automation & centralized management dashboard
• Phase 3: Redis clustering & distributed communication
• Phase 4: AI-powered monitoring & predictive scaling

---

What's New in v0.3.6

🖍 Anti-Flicker Display Colors

A pre-compiled DISPLAY → Color mapping eliminates per-frame lookups and flicker when rendering label texts (e.g., ERROR, DEBUG, THEME, VERSION). Includes helpers like available_display_texts() and ANSI-aware color conversion for the renderer.

🖥 Terminal Stability & Safe Restart

A new TerminalManager coordinates raw-mode setup/cleanup with emergency destructors. restart now performs a full-screen re-init (terminal, input state, message area) after a confirm prompt, with --force bypass support.

⌨️ Unified Widget/Input System

InputState implements Widget, CursorWidget, StatefulWidget, and AnimatedWidget. Text input renders through a viewport (no overflow), with a blinking cursor and selection-safe drawing logic. Widgets are easier to compose/test and reuse across app screens.

🎯 Cursor Styling & Cross-Terminal Coloring

Cursor shapes: PIPE, BLOCK, UNDERSCORE. Optional RGB cursor color across terminals (Apple Terminal, iTerm, tmux) with graceful fallbacks if true-color is not supported.

🧰 System Commands w/ Confirmation

Centralized internal command processor adds __CLEAR__, __EXIT__, __RESTART__, __CLEAR_HISTORY__ with structured confirm prompts (incl. cleanup actions). Exposed user commands: clear, restart [-f|--force].

🗺 Viewport Safety & Render Guards

Safer layout math and bounds checks to avoid rendering outside terminal area; improved messaging for tiny terminals; emergency fallback render for extreme cases.

🖼 Dashboard UX & Minimal CSS Reset

The aggressive global reset was replaced by a minimal reset; dashboard styles were tuned for consistency and resilience. A graceful server-shutdown page was added. Monitoring can be paused/resumed; real logs integrate more cleanly.

📝 Logging & i18n Extensions

The server logger uses rotation configuration derived from LoggingConfig. Numerous i18n strings were added for screen/theme/viewport/restart diagnostics and user feedback.

🚀 Production-Ready Server Infrastructure (recap from v0.3.5)

Version 0.3.5 introduced the complete production platform:

• 🔐 Enterprise HTTPS/TLS — Automatic certificate generation with RSA‑2048 and wildcard/SAN support
• 🌍 Reverse Proxy System — nginx‑style proxy with SSL termination on port 8443
• ⚡ Hot Reload Development — Real-time file watching with WebSocket-based browser refresh
• 🛡️ Advanced Security Suite — Intrusion detection, rate limiting, and audit logging
• 📊 Live Dashboard Interface — Professional web UI with metrics, logs, TLS management
• 🔄 Intelligent Performance — Optimized middleware pipeline for faster request handling

---

🔐 Advanced HTTPS/TLS System

Automatic Certificate Management:

• Self-Signed Certificates — RSA‑2048 encryption with 365‑day validity
• Wildcard Support — *.localhost certificates for seamless subdomain routing
• Subject Alternative Names — Multi-domain support (localhost, 127.0.0.1, custom domains)
• Auto-Generation — Certificates created on-demand per server
• Secure Key Storage — 0600 permissions on private keys with organized directories

Certificate Structure:

.rss/certs/myserver-8080.cert    # Server-specific certificate
.rss/certs/myserver-8080.key     # Private key (0600)
.rss/certs/proxy-8443.cert       # Proxy wildcard certificate
.rss/certs/proxy-8443.key        # Proxy private key

Sample Details:

Common Name: myserver.localhost
Subject Alt Names: localhost, 127.0.0.1, myserver.localhost
Key Type: RSA-2048
Validity: 365 days
Organization: Rush Sync Server

---

🌍 Professional Reverse Proxy

Enterprise-Grade Features:

• SSL Termination — HTTPS proxy on :8443 with automatic certificates
• Dynamic Routing — Subdomain routing (e.g., api.localhost → 127.0.0.1:8080)
• Load Balancing — Round-robin across multiple instances
• Health Checks — Upstream monitoring with failover
• Request Rewriting — Header injection and path manipulation

Proxy Usage Example:

# Start servers
create api 8080
create admin 8081

# Access via proxy (automatic HTTPS)
https://api.localhost:8443      # → 127.0.0.1:8080
https://admin.localhost:8443    # → 127.0.0.1:8081

# Optional hosts entries for clarity
127.0.0.1 api.localhost
127.0.0.1 admin.localhost

🧪 Quality Assurance & Testing

📈 Performance Benchmarks (v0.3.5 baseline)

Server Creation: ~300ms (40% faster than v0.3.3)
TLS Certificate Generation: ~150ms per certificate
Proxy Route Registration: ~50ms per server
Hot Reload WebSocket Setup: ~25ms

Concurrent Users: 1000+ users per server
