Darcs.Patch.Named

Description

`Named` patches group a set of changes with meta data (`PatchInfo`) and explicit dependencies (created using `darcs tag` or using --ask-deps).

While the data constructor `NamedP` is exported for technical reasons, code outside this modules should (and generally does) treat it as an abstract data type. The only exception is the rebase implementation i.e. the modules under Darcs.Patch.Rebase.

# Documentation

data Named (p :: Type -> Type -> Type) wX wY where #

The `Named` type adds a patch info about a patch, that is a name.

`NamedP info deps p` represents patch `p` with name `info`. `deps` is a list of dependencies added at the named patch level, compared with the unnamed level (ie, dependencies added with `darcs record --ask-deps`).

(Commute p, Conflict p, Summary p, PrimPatchBase p, PatchListFormat p, ShowPatch p) => Conflict (Named p) # | This instance takes care of handling the interaction between conflict resolution and explicit dependencies. A conflict involves a set of two or more patches and the general rule is that the conflict is considered resolved if there is another (later) patch that (transitively) depends on each of the (mutually) conflicting patches. This principle extends to explicit dependencies between `Named` patches. In particular, recording a tag has the effect of resolving any as yet unresolved conflicts in a repo. In general a `Named` patch contains multiple changes ( a "changeset"). Consider the named patches
      Named A [] a
      Named B [] (b1;b2)
      Named C [] c
      Named D [A,B] _
where, at the RepoPatch level, `a` conflicts with `b1`, and `c` with `b2`. `D` depends explicitly on both `A` and `B`, so it fully covers the conflict between `a` and `b1` and thus we would be justified to consider that particular conflict as resolved. Unfortunately we cannot detect this at the Named patch level because RepoPatchV1 and V2 have no notion of patch identities. Thus, at the Named level the two underlying conflicts appear as a single large conflict between the three named patches `A`, `B`, and `C`, and this means that patch `D` does not count as a (partial) resolution (even though it arguably should). When we decide that a set of conflicting Named patches is resolved, we move the RepoPatches contained in them to the context of the resolution. For all other named patches, we must commute as much of their contents as possible past the ones marked as resolved, using commutation at the RepoPatch level (i.e. ignoring explicit dependencies).
