Another question: % go ahead and generate the new revision ids for the
documents.
Docs2 = lists:map(
fun(#doc{id=Id,revs=Revs}=Doc) ->
case Id of
<<?LOCAL_DOC_PREFIX, _/binary>> ->
Rev = case Revs of [] -> 0; [Rev0|_] ->
list_to_integer(binary_to_list(Rev0)) end,
Doc#doc{revs=[list_to_binary(integer_to_list(Rev + 1))]};
_ ->
Doc#doc{revs=[list_to_binary(integer_to_list(couch_util:rand32())) | Revs]}
end
end, Docs),
A) we have the same problem with rand32(), from the code, I assume it is
meant to generate a revision that can be unique across nodes, but it is not
guaranteed.
B) What is the meaning of "_local" documents? I couldn't find anything about
it.
