High-performance Python bindings for OpenWrt's ubus (micro bus architecture) using direct libubus C library integration for maximum speed and efficiency.

Architecture: Python → C Extension → libubus → ubusd

• 🔥 Sub-millisecond response times - Same performance as native ubus command
• ⚡ Zero serialization overhead - Direct binary protocol communication
• 🎯 30x faster than HTTP/JSON-RPC - No network stack, no JSON parsing
• 🛠️ Native libubus integration - Exact same code path as OpenWrt tools

Traditional: Python → HTTP → uhttpd → JSON parsing → ubusd
PyUbus:     Python → C Extension → libubus → ubusd

The C extension eliminates all intermediate layers and communicates directly with ubusd using the same binary protocol as OpenWrt's native ubus command-line tool.

• 🔥 Maximum Performance: Direct libubus integration, sub-millisecond calls
• 🎯 OpenWrt-Native: Built specifically for OpenWrt environment
• 🛡️ Reliable: Same stability as native ubus tools
• 🔧 Simple API: Clean, Pythonic interface
• 📦 Lightweight: No external Python dependencies
• 🏷️ Type Hints: Full type annotation support
• 🖥️ CLI Tool: Command-line interface for quick operations
• 🏗️ OpenWrt Integration: UCI configuration and package building support

# Ubuntu/Debian
sudo apt-get install libubus-dev json-c-dev

# Alpine Linux  
apk add libubus-dev json-c-dev

# OpenWrt (available in build system)

git clone https://github.com/ArunEG/pyubus.git
cd pyubus
pip install -e .

The C extension will be built automatically during installation.

# In OpenWrt build system
make menuconfig  # Navigate to Languages → Python → python3-pyubus
make package/lang/python/python3-pyubus/compile

# Use the automated installation script
chmod +x install_openwrt.sh
./install_openwrt.sh

from pyubus import UbusClient

# Connect to local ubus (fastest)
with UbusClient() as client:
    # Get system information (~0.5ms response time)
    system_info = client.call("system", "board")
    print(f"Model: {system_info['model']}")
    
    # List all available ubus objects  
    objects = client.list()
    print(f"Found {len(objects)} ubus objects")
    
    # Network interface status
    lan_status = client.call("network.interface.lan", "status")
    print(f"LAN: {'UP' if lan_status.get('up') else 'DOWN'}")

import time
from pyubus import UbusClient

# Measure actual performance
with UbusClient() as client:
    start_time = time.time()
    
    # Make 100 rapid calls
    for i in range(100):
        client.call("system", "board")
    
    elapsed = (time.time() - start_time) * 1000
    print(f"100 calls completed in {elapsed:.2f}ms")
    print(f"Average: {elapsed/100:.3f}ms per call")

from pyubus import UbusClient

with UbusClient() as client:
    # System monitoring
    system_status = client.get_system_status()
    print(f"Uptime: {system_status['uptime']} seconds")
    
    # Network monitoring  
    interfaces = client.get_network_status()
    for name, status in interfaces.items():
        print(f"{name}: {'UP' if status.get('up') else 'DOWN'}")
    
    # Service management
    client.restart_service("dnsmasq")

UbusClient(socket_path="/var/run/ubus.sock", timeout=30)

Core Methods:

• call(object, method, params=None) - Call ubus method
• list(path=None) - List ubus objects and methods
• connect() - Connect to ubus daemon
• disconnect() - Disconnect from ubus daemon

Convenience Methods:

• get_system_info() - Get system board information
• get_system_status() - Get system status (uptime, memory, load)
• get_network_status(interface=None) - Get network interface status
• get_wireless_status() - Get wireless status information
• restart_service(service_name) - Restart a system service

Properties:

• is_connected - Connection status
• backend_type - Always returns "native"

# List all ubus objects (uses native C extension)
pyubus list

# Get system information  
pyubus call system board

# Network interface status
pyubus call network.interface.lan status

# With custom socket path
pyubus --socket /custom/ubus.sock list

• --socket: Custom ubus socket path
• --timeout: Operation timeout in seconds
• --json: Pretty-print JSON output
• --help: Show help information

# Typical results on OpenWrt device:

# PyUbus C Extension
100 system.board calls: 50ms (0.5ms/call)

# Traditional HTTP/JSON-RPC  
100 system.board calls: 1500ms (15ms/call)

# SSH + ubus command
100 system.board calls: 5000ms (50ms/call)

1. Direct libubus calls - No intermediate layers
2. Binary protocol - No JSON serialization/deserialization
3. Local socket - No network stack overhead
4. Optimized C code - Compiled for maximum performance
5. Memory efficient - Minimal Python object creation

from pyubus import UbusClient, UbusError, UbusConnectionError

try:
    with UbusClient() as client:
        result = client.call("system", "info")
except UbusConnectionError as e:
    print(f"Cannot connect to ubus: {e}")
except UbusError as e:
    print(f"ubus error: {e}")

Exception Types:

• UbusError - Base exception
• UbusConnectionError - Connection issues
• UbusMethodError - Method call errors
• UbusPermissionError - Permission denied
• UbusTimeoutError - Operation timeout

• OpenWrt device with ubusd running
• Python 3.7+ installed on device
• Sufficient storage (~1MB for PyUbus)
