+
+*SOLVER_DISFAVOR*::

by setting this flag.
+*SOLVER_FLAG_NEED_UPDATEPROVIDE*::
+This is somewhat the opposite of SOLVER_FLAG_NO_UPDATEPROVIDE: Only
+packages that provide the installed package names are considered
+for updating.
+
*SOLVER_FLAG_SPLITPROVIDES*::
Make the solver aware of special provides of the form
``<packagename>:<path>'' used in SUSE systems to support package
in no longer working packages in case they are orphaned.
*SOLVER_FLAG_FOCUS_INSTALLED*::
-Resolve installed packages before resolving the given job.
+Resolve installed packages before resolving the given jobs.
Setting this flag means that the solver will prefer picking
a package version that fits the other installed packages
over updating installed packages.
+*SOLVER_FLAG_FOCUS_BEST*::
+First resolve the given jobs, then the dependencies of the
+resulting packages, then resolve all already installed
+packages. This will result in more packages being updated
+as when the flag is not used.
+
+*SOLVER_FLAG_INSTALL_ALSO_UPDATES*::

+package.

+*SOLVER_FLAG_YUM_OBSOLETES*::

+ my @solvables = $solver->get_recommended();
+ solvables = solver.get_recommended()
+ solvables = solver.get_recommended()

The Problem Class
-----------------
Problems are the way of the solver to interact with the user. You can simply list
Rule *findallproblemrules(bool unfiltered = 0)
my @probrules = $problem->findallproblemrules();
- probrules = problem.findallproblemrule()
- probrules = problem.findallproblemrule()
+ probrules = problem.findallproblemrules()
+ probrules = problem.findallproblemrules()
Return all rules responsible for the problem. The returned set of rules contains
all the needed information why there was a problem, but it's hard to present
Create a job that implements the solution element. Add this job to the array
of jobs for all elements of type different to SOLVER_SOLUTION_JOB and
-SOLVER_SOLUTION_POOLJOB. For the later two, a SOLVER_NOOB Job is created,
+SOLVER_SOLUTION_POOLJOB. For the latter two, a SOLVER_NOOB Job is created,
you should replace the old job with the new one.
