Summary0000228: ScoreFunction cloning
DescriptionBecause of the distinction between ScoreFunction and SymmetricScoreFunction (as well as the other ScoreFunction subclasses), you should never use the copy constructor of ScoreFunction() to make a new copy of a ScoreFunction. Use scorefxn.clone() instead.

Note there's no drawback to this, even if you know that you have a true ScoreFunction.
Steps To ReproduceTo find potential violators:

egrep -R 'new[[:space:]]*ScoreFunction[[:space:]]*\([^)]' rosetta/rosetta_source/src

Additional InformationCommand currently finds 66 instances. Some are valid, like the 7 in will and neil's apps/pilot directories, which are explicitly intended to take a symmetric scorefunction and asymmetrize it. Most of the rest are probably latent bugs.

They'll need to be checked manually, though.

Is there a future in privatizing the copy operator to force people to use clone? I am guessing not from your notes.

As Steven suggested: How about declare copy constructor and copy operator as private and never define them? That way it will be impossible to copy without clone.

If we provide a new method for those few people who explicitly want to convert a scorefunction to the base class (with a name that makes it clear that's what they're doing), I think making the copy constructor private might work.
