Upstart scripts are being incorrectly identified as SysV init scripts
due to a logic error in the `service` module.
Because upstart uses multiple commands (`/sbin/start`, `/sbin/stop`,
etc.) for managing service state, the codepath for upstart sets
`self.svc_cmd` to an empty string on line 451.
Empty strings are considered a non-truthy value in Python, so
conditionals which are checking the state of `self.svc_cmd` should
explicitly compare it to `None` to avoid overlooking the fact that
the service may be controlled by an upstart script.
I tried a playbook with the following (accidentally wrong) task:
tasks:
- name: authorized key test
authorized_key: key=/home/sam/.ssh/id_rsa.pub key_options='command="/foo/bar"' user=sam
I got the following traceback:
TASK: [authorized key test] ***************************************************
failed: [localhost] => {"failed": true, "parsed": false}
Traceback (most recent call last):
File "/home/sam/.ansible/tmp/ansible-tmp-1427110003.65-277897441194582/authorized_key", line 2515, in <module>

File "/home/sam/.ansible/tmp/ansible-tmp-1427110003.65-277897441194582/authorized_key", line 460, in main
results = enforce_state(module, module.params)
File "/home/sam/.ansible/tmp/ansible-tmp-1427110003.65-277897441194582/authorized_key", line 385, in enforce_state
parsed_new_key = (parsed_new_key[0], parsed_new_key[1], parsed_options, parsed_new_key[3])
TypeError: 'NoneType' object has no attribute '__getitem__'
With this fix, I see the expected error instead:
TASK: [authorized key test] ***************************************************
failed: [localhost] => {"failed": true}
msg: invalid key specified: /home/sam/.ssh/id_rsa.pub
In cases when the python-apt package is not installed, ansible will
attempt to install it. After this attempt, it tries to import the
needed apt modules, but forgets to import the apt.debfile module.
The result is that playbooks that use the dpkg argument on a machine
that does not initially have the python-apt package available will
fail with the following error
AttributeError: 'module' object has no attribute 'debfile'
This patch adds the appropriate import to the apt module to ensure
that necessary libraries are available in cases when the dpkg argument
is being used on a system that does not initially have the python-apt
package installed
