"""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 ~/.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',
