Conflictor patches

Documentation

data RealPatch prim x y where

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

Etacilpud x: invert (Duplicate x)

Normal prim: A primitive patch

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 current patch

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

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