0.121.jw02 - made rresults an alias for results. python decorators are a strange concept... - asserting that ~/.oscrc remains mode 0600 - no more plain text passwords in ~/.oscrc, we store now as bz2+base64 - added verbosity control -v -q. To be used in guess_proj_pack() - added 'll' and 'ls -l' as shorthand to 'list -v' - started to change to explicit dual license GPLv2 or GPLv3 to conform to Novell policy. - added revision parameter to show_upstream_srcmd5(), so that it can be used in do_cat later. - allowed both integer and srcmd5 revisions in meta_get_filelist() - added 'lL', 'LL': allowed -e and -v together in do_list(). Was an internal error before. - added cat -e, to cat a file through a link. 'cat -e -r 3' expands through the third revision of the _link. - added subcmd bco as alias for branch -c - added default project to branch subcommand. .oscrc:branch_project = OpenSUSE:Factory - added primitive experimental support for .oscrc:checkout_no_colon = 1 - suggest using svn when .svn found. - alias submitpac submitrequest - osc bco now continues to checkout after branch target exists error. - added .oscrc:plaintext_passwd=1 for backwards compatibility - moved core.py:exclude_stuff to .oscrc:exclude_glob and expand it to catch *.orig etc. - allowed req as alias for request. - bugfix get_request_list: use 'or' with multiple states, not 'and'. - added osc req list -s all; a shorthand for enumerating all states - osc req list no longer confuses creator with approver. - osc req list -D nnn limit to requests nnn days old. - osc req list now also shows requests from the the given package, not only to. - improved help texts with repairlink to point to osc resolved. - improved passx code when creating oscrc. - osc sr -l is now a shortcut for 'osc req list -M -a -t submit -D 0'

"""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'},
