How to integrate osc (OBS API communication) in a python code

When complexity creeps up, a simple Bash script can quickly become a very complex, unmaintainable piece of code.

Integrating the osc command into a Python script is an easy alternative to Bash when automating fairly complex tasks. It's very easy to integrate osc in your own python code.

You need to import 2 Packages.</code>

• from osc import conf
• from osc import core

conf: Allow the access to the osc's configuration.[[1]]

core: Provide Functions to communicate with the OBS API.[[2]]

OBS API documentation is available here

Here, a simple example.

#!/usr/bin/python

# This Python script 
#    list of the packages of a project, 
#    get the status, and so, if the status is "failed", rebuild the package.</code>

from osc import conf
from osc import core
from xml.etree import ElementTree

if __name__ == '__main__':
   apiurl="http://obsserver:81"
   prj="MeeGo:1.2.0:oss"
   repos="standard"
   arch="i586"

   #init the osc's configuration.
   aConf=conf.get_config()

   # Use directly the core fonction.
   list_package=core.meta_get_packagelist(apiurl, prj)

   for package in list_package:
       url=apiurl+"/build/"+prj+"/"+repos+"/"+arch+"/"+package+"/_status"

       # You can also use directly the obs API directly.
       aElement=ElementTree.fromstring(core.http_request("GET", url).read())
       code=aElement.attrib["code"]
       print "code",code,
       if code=="failed":
           print "rebuild"
           core.rebuild(apiurl, prj, package, repos, arch)
       else:
           print

For access only, you can also use python-buildservice

python-buildservice documentation is available here [[3]]
