This allows dnf5daemon users to reset their session and re-use it for another transaction.

For: #1653

This interface was dropped.
- fix return code in case of error
- add full_nevra to expected resolve() output
It's currently used to prevent running Goal.do_transaction call multiple
times simultaneously.
This change allow us to easily re-create the session goal object in case
of the base reset.
For resetting the base held in the session we will need to execute this
part of initialization on two places. This patch prevents code
duplication.
This call will re-create libdnf5::Base instance stored in the session.
As a result, the goal and transaction are reset as well.

Thanks for nicely separating the work into commits! BTW, it might be helpful to add a test case for resetting the session and running a new transaction afterward. What do you think?

dnf5daemon-server/services/goal/goal.cpp Show resolved Hide resolved
Since resolve() method re-sets transaction, use transaction mutex to
prevent running Goal.resolve() if another transaction is running.

The unit test implementation is deferred to a separate issue as it's not easy and straightforward with the daemon testing...
