- move all configuration code into module osc/conf.py
- now, the API server can be configured in .oscrc with
apisrv = ...
- also, 'scheme' (http/https) is no longer a module variable but can be
configured
- all config is in DEFAULT
- ignore vim swap files
- use urllib() convenience wrapper in some functions that used
urllib2.urlopen() and had their own error handling. Instead, it seems to make
sense -- in the future-- to create our own errors and propagate them up, in
cases where the error handling of urlopen() is too generic
- rename get_slash_source() to meta_get_project_list() for consistency
- show local time in get_buildhistory(), not UTC
- rewrite help text of 'rebuildpac' command
- allow to run commandline.py from the commandline (without the wrapper)
- don't send a space when doing a POST request without body
