    solver: new package selection logic (which is not yet used) · 79b53d4d
    Timo Teräs authored
     * basic code for a backtracking, forward checking dependency satisfier
     * works better when there are tricky dependencies to solve
       (when can't just upgrade everything to most preferred versions)
     * the new code always evaluates all of 'world' constraints
       (old code just does incremental updates based on heuristics)
     * is probably somewhat slower than old code (probably unnoticeable
       difference in most cases)
     * makes easier to write support for provides and repository pinning
     * test applet and a bunch of test cases added which uses the new code
     * from the old feature set install_if is not yet implemented
