Hi!
It seems that protobuffers client doesn't allow to update metadata of
object.
Example:
<code>
-module(test).
-compile(export_all).
test1(Host, Port) ->
{ok,C} = riakc_pb_socket:start_link(Host, Port),
O0 = riakc_obj:new(<<"b">>, <<"k">>, <<"d">>),
{ok, O1} = riakc_pb_socket:put(C, O0, [return_body]),
M1 = riakc_obj:get_metadata(O1),
M2 = dict:store(<<"Links">>, [{{<<"b">>, <<"k1">>}, <<"t1">>}], M1),
O2 = riakc_obj:update_metadata(O1, M2),
riakc_pb_socket:put(C, O2).
</code>
Runnig test:test1("localhost", 8081), I see error
{error,{required_field_is_undefined,1,bytes}}.
After tracing I realised that missing field is Value from RpbContent
structure.
So updating value with riakc_obj:update_value/2 before calling put does the
trick.
But I think metadata supposed to be updated without need of updating value.
