The Service object now offers handling services on a system level,
and gathering information whether it's enabled or running.
New methods: enable, disable, is_enabled, is_running;
For this it needs the correct (system-level) service name.
All of the methods can be overridden/customized.
This changes all modules to the new Service object and deletes
action scripts that are not required anymore.
- To check whether a service is running does not require root
privileges. This can directly be done from a module without any
action.
- Since actions are allowed to be run using sudo, introducing
unnecessary sub-commands increases attack surface.
- Simple functions calls are unnecessarily being converted to command
line invocations and involve parsing response.
- There is a lot of repeated code because of this that can be
eliminated.
- To generalize this, we need to make all non-root system operations
directly from module instead of delegating to action commands.
- Merge actions/pagekite_util.py into plinth/modules/pagekite/util.py.
- Rename plinth/modules/pagekite/util.py to utils.py.
- Add python-augeus as dependency.
- Move actions/util.py to plinth/action_utils.py and update services
that use it.
- Rename _run() method to run() as it is being used publicly.
- Import the utils in a more conventional manner.
- Move all python2 bits to python3.
