Robert Newson commented on COUCHDB-1950:
----------------------------------------

This is confusing. You're asking me to elaborate on the thing I said we sho=
uld not do at all (actually resolve conflicts).

On another ticket, one about the read-time ddoc-mediate choice of 'winning'=
 leaf, I would elaborate a bit more (though it seems pretty straightforward=
).

 hook here I could refer to in another conversation, so=E2=80=A6
> It'd be great if a design document could include a conflict resolver func=
tion, in the vein of other "app logic" handler hooks like validate_doc_writ=
e. I imagine it would look something like either "function (currentWinner, =
nextWinningestLoser, parent)" (simply called multiple times if more than 2 =
leafs) or simply "function (arrayOfDocs, revisionHistor)" =E2=80=94 if it r=
eturns a document, that's the winner, if not the next design document in li=
ne gets a pass at it. (Bonus: if it throws, the conflict stays no matter wh=
at other resolvers say?)
