"""Read osc configuration and store it in a dictionary This module reads and parses oscrc. The resulting configuration is stored for later usage in a dictionary named 'config'. The oscrc is kept mode 0600, so that it is not publically readable. This gives no real security for storing passwords. If in doubt, use your favourite keyring. Password is stored on ~/.config/osc/oscrc as bz2 compressed and base64 encoded, so that is fairly large and not to be recognized or remembered easily by an occasional spectator. If information is missing, it asks the user questions. After reading the config, urllib2 is initialized. The configuration dictionary could look like this: {'apisrv': 'https://api.opensuse.org/', 'user': 'joe', 'api_host_options': {'api.opensuse.org': {'user': 'joe', 'pass': 'secret'}, 'apitest.opensuse.org': {'user': 'joe', 'pass': 'secret', 'http_headers':(('Host','api.suse.de'), ('User','faye'))}, 'foo.opensuse.org': {'user': 'foo', 'pass': 'foo'}}, 'build-cmd': '/usr/bin/build', 'build-root': '/abuild/oscbuild-%(repo)s-%(arch)s', 'packagecachedir': '/var/cache/osbuild', 'su-wrapper': 'sudo', } """ import bz2 import errno import getpass import os import re import sys from io import StringIO from urllib.parse import urlsplit from . import credentials from . import OscConfigParser from . import oscerr from .util.helper import raw_input GENERIC_KEYRING = False try: import keyring GENERIC_KEYRING = True except: pass def _get_processors(): """ get number of processors (online) based on SC_NPROCESSORS_ONLN (returns 1 if config name/os.sysconf does not exist).
