# SkyView Database Auto-Update with Cron
|
||||
|
||||
This guide explains how to set up automatic database updates for SkyView using cron jobs.
|
||||
|
||||
## Overview
|
||||
|
||||
SkyView can automatically update its aviation database from public domain sources using cron jobs. This ensures your aircraft callsign data stays current without manual intervention.
|
||||
|
||||
## Features
|
||||
|
||||
- ✅ **Auto-initialization**: Creates empty database if it doesn't exist
|
||||
- ✅ **Safe sources only**: Updates only public domain data (no license issues)
|
||||
- ✅ **Cron-friendly**: Proper logging and exit codes for automated execution
|
||||
- ✅ **Lock file protection**: Prevents concurrent updates
|
||||
- ✅ **Error handling**: Graceful failure handling with logging
|
||||
|
||||
## Quick Setup
|
||||
|
||||
### 1. Command Line Tool
|
||||
|
||||
The `skyview-data` command is designed to work perfectly with cron:
|
||||
|
||||
```bash
|
||||
# Auto-initialize database and update safe sources
|
||||
skyview-data update
|
||||
|
||||
# Check what's loaded
|
||||
skyview-data status
|
||||
|
||||
# List available sources
|
||||
skyview-data list
|
||||
```
|
||||
|
||||
### 2. Cron Job Examples
|
||||
|
||||
#### Daily Update (Recommended)
|
||||
```bash
|
||||
# Add to crontab: crontab -e
|
||||
# Update database daily at 3 AM
|
||||
0 3 * * * /usr/bin/skyview-data update >/var/log/skyview-update.log 2>&1
|
||||
```
|
||||
|
||||
#### Weekly Update
|
||||
```bash
|
||||
# Update database weekly on Sunday at 2 AM
|
||||
0 2 * * 0 /usr/bin/skyview-data update >/var/log/skyview-update.log 2>&1
|
||||
```
|
||||
|
||||
#### With Helper Script (Debian Package)
|
||||
```bash
|
||||
# Use the provided update script
|
||||
0 3 * * * /usr/share/skyview/scripts/update-database.sh
|
||||
```
|
||||
|
||||
### 3. System Service User
|
||||
|
||||
For Debian package installations, use the skyview service user:
|
||||
|
||||
```bash
|
||||
# Edit skyview user's crontab
|
||||
sudo crontab -u skyview -e
|
||||
|
||||
# Add daily update
|
||||
0 3 * * * /usr/bin/skyview-data update
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Database Location
|
||||
|
||||
The tool automatically detects the database location:
|
||||
- **System service**: `/var/lib/skyview/skyview.db`
|
||||
- **User install**: `~/.local/share/skyview/skyview.db`
|
||||
- **Current directory**: `./skyview.db`
|
||||
|
||||
### Custom Database Path
|
||||
|
||||
```bash
|
||||
# Specify custom database location
|
||||
skyview-data -db /custom/path/skyview.db update
|
||||
```
|
||||
|
||||
### Logging
|
||||
|
||||
For cron jobs, redirect output to log files:
|
||||
|
||||
```bash
|
||||
# Basic logging
|
||||
skyview-data update >> /var/log/skyview-update.log 2>&1
|
||||
|
||||
# With timestamps (using helper script)
|
||||
/usr/share/skyview/scripts/update-database.sh
|
||||
```
|
||||
|
||||
## Data Sources
|
||||
|
||||
### Safe Sources (Auto-Updated)
|
||||
|
||||
These sources are automatically included in `skyview-data update`:
|
||||
|
||||
- **OurAirports**: Public domain airport data
|
||||
- **FAA Registry**: US aircraft registration (public domain)
|
||||
- *(Additional safe sources as they become available)*
|
||||
|
||||
### License-Required Sources
|
||||
|
||||
These require explicit acceptance and are NOT included in automatic updates:
|
||||
|
||||
- **OpenFlights**: AGPL-3.0 licensed airline/airport data
|
||||
|
||||
To include license-required sources:
|
||||
```bash
|
||||
# Interactive acceptance
|
||||
skyview-data import openflights
|
||||
|
||||
# Force acceptance (for automation)
|
||||
skyview-data update openflights --force
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Check Update Status
|
||||
|
||||
```bash
|
||||
# View database status
|
||||
skyview-data status
|
||||
|
||||
# Example output:
|
||||

|
||||
```
|
||||
|
||||
### Log Monitoring
|
||||
|
||||
```bash
|
||||
# View recent updates
|
||||
tail -f /var/log/skyview-update.log
|
||||
|
||||
# Check for errors
|
||||
grep ERROR /var/log/skyview-update.log
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### Database Not Found
|
||||
```
|
||||
ERROR: failed to create database: no write permission
|
||||
```
|
||||
**Solution**: Ensure the skyview user has write access to `/var/lib/skyview/`
|
||||
|
||||
#### Network Errors
|
||||
```
|
||||
ERROR: failed to download data: connection timeout
|
||||
```
|
||||
**Solution**: Check internet connectivity and firewall settings
|
||||
|
||||
#### Lock File Issues
|
||||
```
|
||||
ERROR: Another instance is already running
|
||||
```
|
||||
**Solution**: Wait for current update to finish, or remove stale lock file
|
||||
|
||||
### Manual Debugging
|
||||
|
||||
```bash
|
||||
# Verbose output
|
||||
skyview-data -v update
|
||||
|
||||
# Force update (skips locks)
|
||||
skyview-data update --force
|
||||
|
||||
# Reset database
|
||||
skyview-data reset --force
|
||||
```
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Custom Update Script
|
||||
|
||||
Create your own update script with custom logic:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# custom-update.sh
|
||||
|
||||
# Only update if database is older than 7 days
|
||||
if [ "$(find /var/lib/skyview/skyview.db -mtime +7)" ]; then
|
||||
skyview-data update
|
||||
systemctl reload skyview # Reload SkyView after update
|
||||
fi
|
||||
```
|
||||
|
||||
### Integration with SkyView Service
|
||||
|
||||
```bash
|
||||
# Reload SkyView after database updates
|
||||
skyview-data update && systemctl reload skyview
|
||||
```
|
||||
|
||||
### Backup Before Updates
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# backup-and-update.sh
|
||||
|
||||
DB_PATH="/var/lib/skyview/skyview.db"
|
||||
BACKUP_DIR="/var/backups/skyview"
|
||||
|
||||
# Create backup
|
||||
mkdir -p "$BACKUP_DIR"
|
||||
cp "$DB_PATH" "$BACKUP_DIR/skyview-$(date +%Y%m%d).db"
|
||||
|
||||
# Keep only last 7 backups
|
||||
find "$BACKUP_DIR" -name "skyview-*.db" -type f -mtime +7 -delete
|
||||
|
||||
# Update database
|
||||
skyview-data update
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### File Permissions
|
||||
|
||||
```bash
|
||||
# Secure database directory
|
||||
sudo chown skyview:skyview /var/lib/skyview
|
||||
sudo chmod 755 /var/lib/skyview
|
||||
sudo chmod 644 /var/lib/skyview/skyview.db
|
||||
```
|
||||
|
||||
### Network Security
|
||||
|
||||
- Updates only download from trusted sources (GitHub, government sites)
|
||||
- All downloads use HTTPS
|
||||
- No sensitive data is transmitted
|
||||
- Local processing only
|
||||
|
||||
### Resource Limits
|
||||
|
||||
```bash
|
||||
# Limit resources in cron (optional)
|
||||
0 3 * * * timeout 30m nice -n 10 skyview-data update
|
||||
```
|
||||
|
||||
This setup ensures your SkyView installation maintains up-to-date aviation data automatically while respecting all license requirements and security best practices.

# SkyView Database Architecture
|
||||
|
||||
This document describes SkyView's SQLite database architecture, migration system, and integration approach for persistent data storage.
|
||||
|
||||
## Overview
|
||||
|
||||
SkyView uses a single SQLite database to store:
|
||||
- **Historic aircraft data**: Position history, message counts, signal strength
|
||||
- **Callsign lookup data**: Cached airline/airport information from external APIs
|
||||
- **Embedded aviation data**: OpenFlights airline and airport databases
|
||||
|
||||
## Database Design Principles
|
||||
|
||||
### Embedded Architecture
|
||||
- Single SQLite file for all persistent data
|
||||
- No external database dependencies
|
||||
- Self-contained deployment with embedded schemas
|
||||
- Backward compatibility through versioned migrations
|
||||
|
||||
### Performance Optimization
|
||||
- Strategic indexing for time-series aircraft data
|
||||
- Efficient lookups for callsign enhancement
|
||||
- Configurable data retention policies
|
||||
- Query optimization for real-time operations
|
||||
|
||||
### Data Safety
|
||||
- Atomic migration transactions
|
||||
- Pre-migration backups for destructive changes
|
||||
- Data loss warnings for schema changes
|
||||
- Rollback capabilities where possible
|
||||
|
||||
## Database Schema
|
||||
|
||||
### Core Tables
|
||||
|
||||
#### `schema_info`
|
||||
Tracks database version and applied migrations:
|
||||
```sql
|
||||
CREATE TABLE schema_info (
|
||||
version INTEGER PRIMARY KEY,
|
||||
applied_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
|
||||
description TEXT,
|
||||
checksum TEXT
|
||||
);
|
||||
```
|
||||
|
||||
#### `aircraft_history`
|
||||
Stores time-series aircraft position and message data:
|
||||
```sql
|
||||
CREATE TABLE aircraft_history (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
icao_hex TEXT NOT NULL,
|
||||
timestamp TIMESTAMP NOT NULL,
|
||||
latitude REAL,
|
||||
longitude REAL,
|
||||
altitude INTEGER,
|
||||
speed INTEGER,
|
||||
track INTEGER,
|
||||
vertical_rate INTEGER,
|
||||
squawk TEXT,
|
||||
callsign TEXT,
|
||||
source_id TEXT,
|
||||
signal_strength REAL,
|
||||
message_count INTEGER DEFAULT 1
|
||||
);
|
||||
```
|
||||
|
||||
**Indexes:**
|
||||
- `idx_aircraft_history_icao_time`: Fast queries by aircraft and time range
|
||||
- `idx_aircraft_history_timestamp`: Time-based cleanup and queries
|
||||
- `idx_aircraft_history_callsign`: Callsign-based searches
|
||||
|
||||
#### `airlines`
|
||||
OpenFlights embedded airline database:
|
||||
```sql
|
||||
CREATE TABLE airlines (
|
||||
id INTEGER PRIMARY KEY,
|
||||
name TEXT NOT NULL,
|
||||
alias TEXT,
|
||||
iata TEXT,
|
||||
icao TEXT,
|
||||
callsign TEXT,
|
||||
country TEXT,
|
||||
active BOOLEAN DEFAULT 1
|
||||
);
|
||||
```
|
||||
|
||||
**Indexes:**
|
||||
- `idx_airlines_icao`: ICAO code lookup (primary for callsign enhancement)
|
||||
- `idx_airlines_iata`: IATA code lookup
|
||||
|
||||
#### `airports`
|
||||
OpenFlights embedded airport database:
|
||||
```sql
|
||||
CREATE TABLE airports (
|
||||
id INTEGER PRIMARY KEY,
|
||||
name TEXT NOT NULL,
|
||||
city TEXT,
|
||||
country TEXT,
|
||||
iata TEXT,
|
||||
icao TEXT,
|
||||
latitude REAL,
|
||||
longitude REAL,
|
||||
altitude INTEGER,
|
||||
timezone_offset REAL,
|
||||
dst_type TEXT,
|
||||
timezone TEXT
|
||||
);
|
||||
```
|
||||
|
||||
**Indexes:**
|
||||
- `idx_airports_icao`: ICAO code lookup
|
||||
- `idx_airports_iata`: IATA code lookup
|
||||
|
||||
#### `callsign_cache`
|
||||
Caches external API lookups for callsign enhancement:
|
||||
```sql
|
||||
CREATE TABLE callsign_cache (
|
||||
callsign TEXT PRIMARY KEY,
|
||||
airline_icao TEXT,
|
||||
airline_name TEXT,
|
||||
flight_number TEXT,
|
||||
origin_iata TEXT,
|
||||
destination_iata TEXT,
|
||||
aircraft_type TEXT,
|
||||
cached_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
|
||||
expires_at TIMESTAMP,
|
||||
source TEXT DEFAULT 'local'
|
||||
);
|
||||
```
|
||||
|
||||
**Indexes:**
|
||||
- `idx_callsign_cache_expires`: Efficient cache cleanup
|
||||
|
||||
## Database Location Strategy
|
||||
|
||||
### Path Resolution Order
|
||||
1. **Explicit configuration**: `database.path` in config file
|
||||
2. **System service**: `/var/lib/skyview/skyview.db`
|
||||
3. **User mode**: `~/.local/share/skyview/skyview.db`
|
||||
4. **Fallback**: `./skyview.db` in current directory
|
||||
|
||||
### Directory Permissions
|
||||
- System: `root:root` with `755` permissions for `/var/lib/skyview/`
|
||||
- User: User-owned directories with standard permissions
|
||||
- Service: `skyview:skyview` user/group for system service
|
||||
|
||||
## Migration System
|
||||
|
||||
### Migration Structure
|
||||
```go
|
||||
type Migration struct {
|
||||
Version int // Sequential version number
|
||||
Description string // Human-readable description
|
||||
Up string // SQL for applying migration
|
||||
Down string // SQL for rollback (optional)
|
||||
DataLoss bool // Warning flag for destructive changes
|
||||
}
|
||||
```
|
||||
|
||||
### Migration Process
|
||||
1. **Version Check**: Compare current schema version with available migrations
|
||||
2. **Backup**: Create automatic backup before destructive changes
|
||||
3. **Transaction**: Wrap each migration in atomic transaction
|
||||
4. **Validation**: Verify schema integrity after migration
|
||||
5. **Logging**: Record successful migrations in `schema_info`
|
||||
|
||||
### Data Loss Protection
|
||||
- Migrations marked with `DataLoss: true` require explicit user consent
|
||||
- Automatic backups created before destructive operations
|
||||
- Warning messages displayed during upgrade process
|
||||
- Rollback SQL provided where possible
|
||||
|
||||
### Example Migration Sequence
|
||||
```go

## Debian Package Integration
|
||||
|
||||
### Package Structure
|
||||
```
|
||||
/var/lib/skyview/ # Database directory
|
||||
/etc/skyview/config.json # Default configuration
|
||||
/usr/bin/skyview # Main application
|
||||
/usr/share/skyview/ # Embedded resources
|
||||
```
|
||||
|
||||
### Installation Process
|
||||
1. **`postinst`**: Create directories, user accounts, permissions
|
||||
2. **First Run**: Database initialization and migration on startup
|
||||
3. **Upgrades**: Automatic schema migration with backup
|
||||
4. **Service**: Systemd integration with proper database access
|
||||
|
||||
### Service User
|
||||
- User: `skyview`
|
||||
- Home: `/var/lib/skyview`
|
||||
- Shell: `/bin/false` (service account)
|
||||
- Database: Read/write access to `/var/lib/skyview/`
|
||||
|
||||
## Data Retention and Cleanup
|
||||
|
||||
### Automatic Cleanup
|
||||
- **Aircraft History**: Configurable retention period (`max_history_days`)
|
||||
- **Cache Expiration**: TTL-based cleanup of external API cache
|
||||
- **Optimization**: Periodic VACUUM operations for storage efficiency
|
||||
|
||||
### Manual Maintenance
|
||||
```sql
|
||||
-- Clean old aircraft history (example: 7 days)
|
||||
DELETE FROM aircraft_history
|
||||
WHERE timestamp < datetime('now', '-7 days');
|
||||
|
||||
-- Clean expired cache entries
|
||||
DELETE FROM callsign_cache
|
||||
WHERE expires_at < datetime('now');
|
||||
|
||||
-- Optimize database storage
|
||||
VACUUM;
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Query Optimization
|
||||
- Time-range queries use `idx_aircraft_history_icao_time`
|
||||
- Callsign lookups prioritize local cache over external APIs
|
||||
- Bulk operations use transactions for consistency
|
||||
|
||||
### Storage Efficiency
|
||||
- Configurable history limits prevent unbounded growth
|
||||
- Periodic VACUUM operations reclaim deleted space
|
||||
- Compressed timestamps and efficient data types
|
||||
|
||||
### Memory Usage
|
||||
- WAL mode for concurrent read/write access
|
||||
- Connection pooling for multiple goroutines
|
||||
- Prepared statements for repeated queries
|
||||
|
||||
## Privacy and Security
|
||||
|
||||
### Privacy Mode
|
||||
SkyView includes comprehensive privacy controls through the `privacy_mode` configuration option:
|
||||
|
||||
```json
|
||||
{
|
||||
"callsign": {
|
||||
"enabled": true,
|
||||
"privacy_mode": true,
|
||||
"external_apis": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Privacy Mode Features
|
||||
- **No External Calls**: Completely disables all external API requests
|
||||
- **Local-Only Lookups**: Uses only embedded OpenFlights database for callsign enhancement
|
||||
- **No Data Transmission**: Aircraft data never leaves the local system
|
||||
- **Compliance**: Suitable for sensitive environments requiring air-gapped operation
|
||||
|
||||
#### Privacy Mode Behavior
|
||||
| Feature | Privacy Mode ON | Privacy Mode OFF |
|
||||
|---------|----------------|------------------|
|
||||
| External API calls | ❌ Disabled | ✅ Configurable |
|
||||
| OpenFlights lookup | ✅ Enabled | ✅ Enabled |
|
||||
| Callsign caching | ✅ Local only | ✅ Full caching |
|
||||
| Data transmission | ❌ None | ⚠️ API calls only |
|
||||
|
||||
#### Use Cases for Privacy Mode
|
||||
- **Military installations**: No external data transmission allowed
|
||||
- **Air-gapped networks**: No internet connectivity available
|
||||
- **Corporate policies**: External API usage prohibited
|
||||
- **Personal privacy**: User preference for local-only operation
|
||||
|
||||
### Security Considerations
|
||||
|
||||
#### File Permissions
|
||||
- Database files readable only by skyview user/group
|
||||
- Configuration files protected from unauthorized access
|
||||
- Backup files inherit secure permissions
|
||||
|
||||
#### Data Protection
|
||||
- Local SQLite database with file-system level security
|
||||
- No cloud storage or external database dependencies
|
||||
- All aviation data processed and stored locally
|
||||
|
||||
#### Network Security
|
||||
- External API calls (when enabled) use HTTPS only
|
||||
- No persistent connections to external services
|
||||
- Optional certificate validation for API endpoints
|
||||
|
||||
### Data Integrity
|
||||
- Foreign key constraints where applicable
|
||||
- Transaction isolation for concurrent operations
|
||||
- Checksums for migration verification
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### Database Locked
|
||||
```
|
||||
Error: database is locked
|
||||
```
|
||||
**Solution**: Stop SkyView service, check for stale lock files, restart
|
||||
|
||||
#### Migration Failures
|
||||
```
|
||||
Error: migration 3 failed: table already exists
|
||||
```
|
||||
**Solution**: Check schema version, restore from backup, retry migration
|
||||
|
||||
#### Permission Denied
|
||||
```
|
||||
Error: unable to open database file
|
||||
```
|
||||
**Solution**: Verify file permissions, check directory ownership, ensure disk space
|
||||
|
||||
### Diagnostic Commands
|
||||
```bash
|
||||
# Check database integrity
|
||||
sqlite3 /var/lib/skyview/skyview.db "PRAGMA integrity_check;"
|
||||
|
||||
# View schema version
|
||||
sqlite3 /var/lib/skyview/skyview.db "SELECT * FROM schema_info;"
|
||||
|
||||
# Database statistics
|
||||
sqlite3 /var/lib/skyview/skyview.db ".dbinfo"
|
||||
```
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Planned Features
|
||||
- **Compression**: Time-series compression for long-term storage
|
||||
- **Partitioning**: Date-based partitioning for large datasets
|
||||
- **Replication**: Read replica support for high-availability setups
|
||||
- **Analytics**: Built-in reporting and statistics tables
|
||||
|
||||
### Migration Path
|
||||
- All enhancements will use versioned migrations
|
||||
- Backward compatibility maintained for existing installations
|
||||
- Data preservation prioritized over schema optimization

# SkyView Database Migration Guide
|
||||
|
||||
This guide covers the transition from SkyView's in-memory data storage to persistent SQLite database storage, introduced in version 0.1.0.
|
||||
|
||||
## Overview of Changes
|
||||
|
||||
### What's New
|
||||
- **Persistent Storage**: Aircraft position history survives restarts
|
||||
- **Callsign Enhancement**: Enriched aircraft information with airline/airport data
|
||||
- **Embedded Aviation Database**: OpenFlights airline and airport data included
|
||||
- **Configurable Retention**: Control how long historical data is kept
|
||||
- **Privacy Controls**: Comprehensive privacy mode for sensitive environments
|
||||
|
||||
### What's Changed
|
||||
- **Memory Usage**: Reduced memory footprint for aircraft tracking
|
||||
- **Startup Time**: Slightly longer initial startup due to database initialization
|
||||
- **Configuration**: New database and callsign configuration sections
|
||||
- **File Structure**: New database file created in system or user directories
|
||||
|
||||
## Pre-Migration Checklist
|
||||
|
||||
### System Requirements
|
||||
- **Disk Space**: Minimum 100MB available for database and backups
|
||||
- **Permissions**: Write access to `/var/lib/skyview/` (system) or `~/.local/share/skyview/` (user)
|
||||
- **SQLite**: No additional installation required (embedded in SkyView)
|
||||
|
||||
### Current Data
|
||||
⚠️ **Important**: In-memory aircraft data from previous versions cannot be preserved during migration. Historical tracking will start fresh after the upgrade.
|
||||
|
||||
## Migration Process
|
||||
|
||||
### Automatic Migration (Recommended)
|
||||
|
||||
#### For Debian Package Users
|
||||
```bash
|
||||
# Update to new version
|
||||
sudo apt update && sudo apt upgrade skyview-adsb
|
||||
|
||||
# Service will automatically restart and initialize database
|
||||
sudo systemctl status skyview
|
||||
```
|
||||
|
||||
#### For Manual Installation Users
|
||||
```bash
|
||||
# Stop current SkyView instance
|
||||
sudo systemctl stop skyview # or kill existing process
|
||||
|
||||
# Backup current configuration
|
||||
cp /etc/skyview/config.json /etc/skyview/config.json.backup
|
||||
|
||||
# Start new version (database will be created automatically)
|
||||
sudo systemctl start skyview
|
||||
```
|
||||
|
||||
### Manual Database Setup
|
||||
|
||||
If automatic initialization fails, you can manually initialize the database:
|
||||
|
||||
```bash
|
||||
# Create database directory
|
||||
sudo mkdir -p /var/lib/skyview
|
||||
sudo chown skyview:skyview /var/lib/skyview
|
||||
|
||||
# Run SkyView with explicit database initialization
|
||||
sudo -u skyview /usr/bin/skyview --init-database --config /etc/skyview/config.json
|
||||
```
|
||||
|
||||
## Configuration Updates
|
||||
|
||||
### New Configuration Sections
|
||||
|
||||
Add these sections to your existing `config.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"database": {
|
||||
"path": "",
|
||||
"max_history_days": 7,
|
||||
"backup_on_upgrade": true
|
||||
},
|
||||
"callsign": {
|
||||
"enabled": true,
|
||||
"cache_hours": 24,
|
||||
"external_apis": true,
|
||||
"privacy_mode": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Configuration Migration
|
||||
|
||||
#### Default System Configuration
|
||||
The new default configuration will be created at `/etc/skyview/config.json` if it doesn't exist:
|
||||
|
||||
```json
|
||||
{
|
||||
"server": {
|
||||
"host": "",
|
||||
"port": 8080
|
||||
},
|
||||
"sources": [
|
||||
{
|
||||
"id": "local",
|
||||
"name": "Local Receiver",
|
||||
"host": "localhost",
|
||||
"port": 30005,
|
||||
"format": "beast",
|
||||
"latitude": 0,
|
||||
"longitude": 0,
|
||||
"altitude": 0,
|
||||
"enabled": true
|
||||
}
|
||||
],
|
||||
"settings": {
|
||||
"history_limit": 500,
|
||||
"stale_timeout": 60,
|
||||
"update_rate": 1
|
||||
},
|
||||
"origin": {
|
||||
"latitude": 51.4700,
|
||||
"longitude": -0.4600,
|
||||
"name": "Default Origin"
|
||||
},
|
||||
"database": {
|
||||
"path": "",
|
||||
"max_history_days": 7,
|
||||
"backup_on_upgrade": true
|
||||
},
|
||||
"callsign": {
|
||||
"enabled": true,
|
||||
"cache_hours": 24,
|
||||
"external_apis": true,
|
||||
"privacy_mode": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Preserving Custom Settings
|
||||
|
||||
If you have customized your configuration, merge your existing settings with the new sections:
|
||||
|
||||
```bash
|
||||
# Backup original
|
||||
cp /etc/skyview/config.json /etc/skyview/config.json.original
|
||||
|
||||
# Edit configuration to add new sections
|
||||
sudo nano /etc/skyview/config.json
|
||||
```
|
||||
|
||||
## Privacy Configuration
|
||||
|
||||
### Enabling Privacy Mode
|
||||
|
||||
For sensitive environments that require no external data transmission:
|
||||
|
||||
```json
|
||||
{
|
||||
"callsign": {
|
||||
"enabled": true,
|
||||
"external_apis": false,
|
||||
"privacy_mode": true,
|
||||
"cache_hours": 168
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Privacy Mode Features
|
||||
- **No External API Calls**: Completely disables OpenSky Network and other external APIs
|
||||
- **Local-Only Enhancement**: Uses embedded OpenFlights data for callsign lookup
|
||||
- **Offline Operation**: Full functionality without internet connectivity
|
||||
- **Compliance Ready**: Suitable for air-gapped or restricted networks
|
||||
|
||||
## Post-Migration Verification
|
||||
|
||||
### Database Verification
|
||||
```bash
|
||||
# Check database file exists and has correct permissions
|
||||
ls -la /var/lib/skyview/skyview.db
|
||||
# Should show: -rw-r--r-- 1 skyview skyview [size] [date] skyview.db
|
||||
|
||||
# Verify database schema
|
||||
sqlite3 /var/lib/skyview/skyview.db "SELECT version FROM schema_info ORDER BY version DESC LIMIT 1;"
|
||||
# Should return current schema version number
|
||||
```
|
||||
|
||||
### Service Health Check
|
||||
```bash
|
||||
# Check service status
|
||||
sudo systemctl status skyview
|
||||
|
||||
# Check logs for any errors
|
||||
sudo journalctl -u skyview -f
|
||||
|
||||
# Verify web interface accessibility
|
||||
curl -I http://localhost:8080/
|
||||
# Should return: HTTP/1.1 200 OK
|
||||
```
|
||||
|
||||
### Feature Testing
|
||||
1. **Historical Data**: Verify aircraft positions persist after restart
|
||||
2. **Callsign Enhancement**: Check that airline names appear for aircraft with callsigns
|
||||
3. **Performance**: Monitor memory and CPU usage compared to previous version
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Migration Issues
|
||||
|
||||
#### Database Permission Errors
|
||||
```
|
||||
Error: unable to open database file
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
sudo chown -R skyview:skyview /var/lib/skyview/
|
||||
sudo chmod 755 /var/lib/skyview/
|
||||
sudo chmod 644 /var/lib/skyview/skyview.db
|
||||
```
|
||||
|
||||
#### Migration Failures
|
||||
```
|
||||
Error: migration failed at version X
|
||||
```
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Stop service
|
||||
sudo systemctl stop skyview
|
||||
|
||||
# Remove corrupted database
|
||||
sudo rm /var/lib/skyview/skyview.db
|
||||
|
||||
# Restart service (will recreate database)
|
||||
sudo systemctl start skyview
|
||||
```
|
||||
|
||||
#### Configuration Conflicts
|
||||
```
|
||||
Error: unknown configuration field 'database'
|
||||
```
|
||||
|
||||
**Solution**: Update configuration file with new sections, or reset to default configuration.
|
||||
|
||||
### Rolling Back
|
||||
|
||||
If you need to revert to the previous version:
|
||||
|
||||
```bash
|
||||
# Stop current service
|
||||
sudo systemctl stop skyview
|
||||
|
||||
# Install previous package version
|
||||
sudo apt install skyview-adsb=[previous-version]
|
||||
|
||||
# Remove database directory (optional)
|
||||
sudo rm -rf /var/lib/skyview/
|
||||
|
||||
# Restore original configuration
|
||||
sudo cp /etc/skyview/config.json.backup /etc/skyview/config.json
|
||||
|
||||
# Start service
|
||||
sudo systemctl start skyview
|
||||
```
|
||||
|
||||
⚠️ **Note**: Rolling back will lose all historical aircraft data stored in the database.
|
||||
|
||||
## Performance Impact
|
||||
|
||||
### Expected Changes
|
||||
|
||||
#### Memory Usage
|
||||
- **Before**: ~50-100MB RAM for aircraft tracking
|
||||
- **After**: ~30-60MB RAM (reduced due to database storage)
|
||||
|
||||
#### Disk Usage
|
||||
- **Database**: ~10-50MB depending on retention settings and traffic
|
||||
- **Backups**: Additional ~10-50MB for migration backups
|
||||
|
||||
#### Startup Time
|
||||
- **Before**: 1-2 seconds
|
||||
- **After**: 2-5 seconds (database initialization)
|
||||
|
||||
