Klaus Trainer commented on COUCHDB-902:
---------------------------------------
A remark from davisp on #couchdb IRC made we wondering why in
Doc = case extract_header_rev(Req, couch_httpd:qs_value(Req, "rev")) of
missing_rev -> % make the new doc
couch_doc:validate_docid(DocId),
#doc{id=DocId};
Rev ->
case couch_db:open_doc_revs(Db, DocId, [Rev], []) of
{ok, [{ok, Doc0}]} -> Doc0;
{ok, [Error]} -> throw(Error)
end
end,
couch_db:open_doc_revs/4 is used instead of couch_db:open_doc/2.
I suggest that, if nobody can tell a reason for using open_doc_revs/4 instead
of open_doc/2, the patch should be changed accordingly.
Anyway, I think that this deserves a closer look.
