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 running as current user for performing readonly actions.

There is a DBus system bus service running as root for performing actions there is making changes to the system

This makes it easy to do packaging action from your application no matter what language it is written in, as long as thereis 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 privileged user like root.

dnf-daemon is still under heavy development and the API is not stable or complete yet

Run the following

git clone ...cd dnf-daemonmake test-inst

just run:

make test-verbose

to run the unit test with output to console

or this to just run the unit tests.

make test

Session:

make exit-session

System

make exit-system

Both

make exit-both

session (readonly as current user)

make run-session

system (as root)

make run-system

The dnfdaemon api is documentedhere

The API is under development, so it might change, when we hit version 1.0, API methods will be frozen andAPI method names, parameters and return types will not change in future releases, new API can be added,but the old ones stays as is

• 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 daemonor 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
