• Features: Supports AMD64, ARM64, ARM32, Windows, macOS
• Output: ./temp/ directory with platform-specific binaries

Universal Tools Created

📋 1. Universal Installation Manager (install-manager.sh)

A comprehensive script that provides:

• Interactive Menu: User-friendly selection of deployment methods
• System Detection: Automatically detects available tools (Docker, Podman, Go, SystemD)
• Validation Framework: Tests each installation method thoroughly
• Automated Testing: --test flag validates all methods
• Error Handling: Graceful failure handling and informative messages

Usage:

./install-manager.sh            # Interactive menu
./install-manager.sh --test     # Test all methods
./install-manager.sh systemd    # Direct method selection

🔧 2. Configuration Consistency Checker (check-configs.sh)

Advanced configuration validation tool:

• Multi-Location Checking: Validates configs across all deployment methods
• Auto-Fix Capability: Corrects common TOML field naming issues
• Template Generation: Creates standardized configurations
• Network Resilience Validation: Ensures network features are properly configured

Usage:

./check-configs.sh              # Check all configurations
./check-configs.sh --fix        # Auto-fix common issues
./check-configs.sh --generate   # Generate standard templates

🛠️ 3. Auto-Fix Script (fix-config.sh)

Specialized script for common configuration mistakes:

• Fixes field naming issues (storagepath → storage_path)
• Ensures network resilience configuration consistency
• Creates backups before making changes
• Validates fixes after application

Configuration Templates

Standard Configuration Structure

All deployment methods now use consistent configuration structure:

[server]
listen_address = "8080"
storage_path = "/opt/hmac-file-server/data/uploads"
metrics_enabled = true

[security]
secret = "CHANGE-THIS-SECRET-KEY-MINIMUM-32-CHARACTERS"

[uploads]
networkevents = true
chunkeduploadsenabled = true

[network_resilience]
enabled = true
quality_monitoring = true
upload_resilience = true
# Mobile optimizations available but conservative defaults for servers

Template Locations

• SystemD: ./templates/config-systemd.toml
• Docker: ./templates/config-docker.toml
• Podman: ./templates/config-podman.toml
• Debian: ./templates/config-debian.toml

Network Resilience Integration

Enhanced Mobile Support

• Fast Detection: 1-second network change detection for mobile scenarios
• Quality Monitoring: RTT and packet loss tracking per interface
• Predictive Switching: Switch before complete network failure
• Upload Resilience: Resume uploads across network changes

Configuration Options

• Conservative server defaults (5-second detection)
• Mobile-optimized thresholds available
• Configurable per deployment scenario

User Experience Improvements

1. Consistent Error Messages

• Helpful validation messages with suggestions
• Common mistake detection and auto-correction
• Clear troubleshooting guidance

2. Installation Validation

• Pre-installation system checks
• Post-installation validation
• Service status verification
• Configuration syntax validation

3. Comprehensive Documentation

• README.md: Enhanced with troubleshooting section
• WIKI.MD: Detailed configuration guides
• NETWORK_RESILIENCE_GUIDE.md: Mobile optimization details
• BUILD_GUIDE.md: Multi-architecture build instructions

Testing Results

Latest Test Results (Comprehensive)

✅ SystemD:       Fully functional and validated
✅ Docker:        Image builds successfully, configs auto-created
✅ Podman:        Fully functional with both full and simple deployment
✅ Debian:        Handles Go dependency gracefully
✅ Multi-Arch:    Builds successfully for current platform

Test Coverage

• System capability detection
• Installation script execution
• Configuration validation
• Service status verification
• Binary functionality testing

Troubleshooting Guide

Common Issues and Solutions

1. Configuration Field Names

   • Problem: Using old field names (storagepath, listenport)
   • Solution: Run ./check-configs.sh --fix

2. Network Resilience Not Working

   • Problem: networkevents=false or missing [network_resilience] section
   • Solution: Enable networkevents and add network_resilience section

3. Service Won't Start

   • Problem: Configuration validation errors
   • Solution: Check logs and run configuration validation

4. Docker Build Issues

   • Problem: Missing configuration files
   • Solution: Auto-creation handled by validation framework

Support Commands

# Comprehensive system check
./install-manager.sh --test

# Fix configuration issues
./check-configs.sh --fix

# Generate fresh configurations
./check-configs.sh --generate

# Validate specific deployment
systemctl status hmac-file-server  # SystemD
docker ps | grep hmac-file-server  # Docker
podman ps | grep hmac-file-server  # Podman

Next Steps

Immediate Actions Needed

1. ✅ Fix Podman Script Path: Verify location of deploy-podman.sh COMPLETED
2. Complete Testing: Run full validation on clean system
3. Documentation Update: Ensure all guides reflect new tools

Future Enhancements
