Libzypp Resolver, when adding do not install solvable, nothing happens

English Programming/Scripting
#1

I am write something uses libzypp. There is a lot of code, so I hope problem is in my understanding of libzypp internals.

When some conflict occurs, I show UI to handle it. I forward possible solutions and problems from libzypp to this UI. But… everything worked, but when user select do not install … and my software checks resolve->pool(), there still problem exist (it was no deleted). When selecting other option, the problem disappear.

What can I do wrong?

In a case like this, we need actual information (what was showing on the screen, for example). Otherwise we would only be guessing.

You can maybe look at “/var/log/zypp/history” (requires root) to see what was actually installed or uninstalled.

I probably found problem. I am trying to extend zypp backend of packagekit with dependency handling. Problem is here (backend_install_files_thread function):



for_(it, repo.solvablesBegin(), repo.solvablesEnd()){
        MIL << "Setting " << *it << " for installation" << endl;
        PoolItem(*it).status().setToBeInstalled(ResStatus::USER);
    }

So we set item to be installed. I think problem is with flag ResStatus::USER, so solution removing this package from list to install can not be applied. I will check I can change this flag to another.

Ok. I solved the issue. Problem is somewhere else. I called this code after add solution to solver, so it was apply again.

How to change title to ‘[solved][my bad] …’ or remove this topic?

Your closing post #4 above is sufficient.
