data RealPatch prim x y Source

RealPatch is used to represents prim patches that are duplicates of, or conflict with, another prim patch in the repository.

Normal prim: A primitive patch

Duplicate x: This patch has no effect since x is already present in the repository.

Etacilpud x: invert (Duplicate x)

Conflictor ix xx x: ix is the set of patches: * that conflict with x and also conflict with another patch in the repository. * that conflict with a patch that conflict with x

xx is the sequence of patches that conflict *only* with x

x is the original, conflicting patch.

ix and x are stored as Non objects, which include any necessary context to uniquely define the patch that is referred to.

The intuition is that a Conflictor should have the effect of inverting any patches that x conflicts with, that haven't already been undone by another Conflictor in the repository. Therefore, the effect of a Conflictor is invert xx.

InvConflictor ix xx x: like invert (Conflictor ix xx x)
