I think the problem might be the following lines in the definition of
SolverSolution::update:
if (update)
queue_push2(&job, SOLVER_UPDATE | SOLVER_SOLVABLE_ALL, 0);
When the prerequisite checker calls SolverSolution::update, doesn't this
cause the upgrading of old versions that we want to keep (assuming
"Current" has been selected)? As a quick test, I commented out those
lines and found that setup.exe let me keep an old version of a package.
Maybe you need to add a DISABLE_UPDATE command to the solver task list
to implement "Keep" for packages that would otherwise be updated.
(Disclaimer: I have only looked briefly at the libsolv sources, so what
I'm saying might be complete nonsense.)
