dnf-daemon is a 2 DBus services there make part for dnf's API available for application via DBus calls.
There is a DBus session bus service runnning as current user for performing readonly actions.
There is a DBus system bus service runnning as root for performing actions there is making changes to the system
This make it easy to do packaging action from your application no matter what language it is written in, as long as there is DBus binding for it.
dnf-daemon uses PolicyKit for authentication for the system service, so when you call one of the commands (as normal users) you will get a
PolicyKit dialog to ask for password of a priviledged user like root.
dnf-daemon is still under heavy development and the API is not stable or complete yet
dnfdaemon/ Contains the daemon python source client/ Contains the client API bindings for python 2.x & 3.x test/ Unit test for the daemon and python bindings dbus/ DBus system service setup files policykit1/ PolicyKit authentication setup files
How to install services and python bindings:
Run the following
git clone ... cd dnf-daemon make test-inst
How to test:
to run the unit test with output to console
or this to just run the unit tests.
To make the daemons shutdown
to run the daemons in debug mode from checkout:
session (readonly as current user)
system (as root)
The dnfdaemon api is documented here
The API is under development, so it might change, when we hit version 1.0, API methods will be frozen and API method names, parameters and return types will not change in future releases, new API can be added, but the old ones stays as is
API Addition Checklist:
- Add the new API methods to dnfdaemon-system.py and optional dnfdaemon-session.py
- Add client api method in DnfDaemonBase if it is available in both daemon or in DnfDaemonClient is it is a system only api.
- Add unit tests for the api in test/test-system-api.py and optional to test/test-system-api.py if it exists in the session api
- Update docs/server.rst and docs/client-python.api ( add new api method to members )
- All unit tests must pass (make test) before pushing to github
