 ==== Dependency calculation using SAT solving ==== #dependencies
 
-This task consists of implementing a new dependency engine for MacPorts. The current dependency engine properly deals with installing packages, but it does not deal satisfactorily with [[ticket:126|dependencies on variants]] (and versions), uninstalling and upgrading. This task requires a complete formalization of the use cases (installation, upgrade, uninstallation) and of the user needs before any implementation, as well as a deep understanding of the dependency relations (required for fetching, building, configuring; static and dynamic linking; dependence at runtime).

This task requires understanding the dependency relations (required for fetching, building, configuring; static and dynamic linking; dependence at runtime).
 
 Instead of re-inventing the wheel it might be helpful to use software available to solve the problem of dependency calculation, e.g. by implementing an interface to a [http://www.mancoosi.org/cudf/ Common Upgradeability Description Format]-based SAT solver. Such a solver could generate an execution plan we could propose to the user and finally execute when confirmed. For this task, the MacPorts concept of variants needs to be transformed into a representation the SAT solvers will be able to optimize. If time permits, rolling back on failed updates can also be implemented.
 There is also a [browser:trunk/dports/devel/libCUDF/Portfile libCUDF] port that might be helpful to look at.
