#!/usr/bin/env python3

Generate an auto.conf and associated other config files for a given autobuilder configuration

Called with $1 - The 'nightly' target the autobuilder is running

$2 - The autobuilder step number (a given target can run multiple steps with different configurations)

$3 - The target build directory to configure

$4 - The poky branch name the build is running on

import json import os import sys import subprocess import errno

if len(sys.argv) != 5: print("Incorrect number of parameters, please call as %s ") sys.exit(1)

Strip off "nightly-"

Check if config contains all the listed params

Check if a config boolean is set

Get a configuration variable, check overrides, first, the defaults

def getconfigvar(name, config, target): if target in config['overrides'] and name in config['overrides'][target]: return config['overrides'][target][name] if name in config['defaults']: return config['defaults'][name] return False

Run a command, trigger a traceback with command output if it fails
