Bug 445767

Description of problem:
At present, the createOrUpdatePath API method in configchannel namespace does
not accept binary files and throws a ISE. In xmlrpc binary contents can be
represented using base64 encoding, wrapping the contents between <base64>
</base64>. However createOrUpdatePath API method only deals with directories or
text files.

Version-Release number of selected component (if applicable): 510


How reproducible: always


Steps to Reproduce:
1. Create a config channel 'channel-foo'
2. Create/copy a binary file as '/tmp/binary'
3. Run the following script (setup the variables to your configuraiton)
"""
#!/usr/bin/env python
from xmlrpclib import Server, Binary

SATELLITE_HOST = "<your satellite host>"
SATELLITE_URL = "http://%s/rpc/api" % SATELLITE_HOST
SATELLITE_LOGIN = "admin"
SATELLITE_PASSWORD = "password"
client = xmlrpclib.Server(SATELLITE_URL, verbose=1)
key = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD)
data = Binary(open("/tmp/binary","rb").read())

client.configchannel.createOrUpdatePath(key,'channel-foo', "/tmp/afoo3",False,
dict( contents = data, owner = "root", group = "root", permissions = "777"))
"""
  
Actual results:

500 ISE - typically a class cast exception in the log.

Expected results:

Proper output showing information pertaining to the create configuration file.
