      go/neo/neonet: Teach Dial to autodetect server encoding · ce89d01a
      Kirill Smelkov authored
      NEO/go server accepts preferred encoding of client from start, but
      NEO/py server implements either N or M encoding and disconnects client
      silently if handshake is not exactly what is expected.
      
      However we can teach Dial to retry with different preferred options and
      this way when connection to a NEO/py server, it will essentially
      autodetect which encoding is used and accepted by remote peer.

      go/neo/neonet: MessagePack support for link layer (draft) · 7f1d0c39
      Kirill Smelkov authored
      This patch adds support for serializing packet frames with M encoding on
      the wire. To do so it follows rules defined in
      
          	nexedi/neoppod@9d0bf97a
          	( nexedi/neoppod!11 )
      
      Server handshake is reworked to autodetect client's preferred encoding.
      Client always prefers 'N' for now.

      go/neo/proto: MessagePack support for messages (draft) · e8143557
      Kirill Smelkov authored
      This patch adds proto.Encoding('M') and teaches it to encode/decode
      messages via MessagePack by the rules defined in
      
      	nexedi/neoppod@9d0bf97a
      	( nexedi/neoppod!11 )
      
      It only adds support for messages serialization, without changing
      proto.go to match changes in e.g. enums reordering, and without adding
      support for MessagePack at link layer in neonet.
      
      M-encoding was only tested for NEO/go-NEO/go, and was not yet tested for
      NEO/go-NEO/py interoperation. There will be likely small mistakes
      discovered on my side that should be hopefully easy to fix step by step
      once we get to that phase.

      go/neo/internal/msgpack: New package with runtime support for MessagePack · a8249bd9
      Kirill Smelkov authored
      It complements github.com/tinylib/msgp with things that neo/proto needs
      to encode/decode messages.

      It is noop for 'N' encoding, but will be non-empty for MessagePack.

      go/neo/proto: protogen: Factor-out handling of slice and map heads into common place · 6e705e4e
      Kirill Smelkov authored
      genSliceHead and genMapHead will be reused for MsgPack encoding.
      Changes in generated code are mostly due to move of where things are
      typecasted to e.g. uint32 without any change in semantic.

      go/neo/proto: protogen: Fix naming thinko in decoderN.genBuf · 1bb595cf
      Kirill Smelkov authored
      For decode-family of functions protogen.go sticks to convention to name
      target variable to where to assign the result as "assignto", not "path".
      
      No change in generated code.

      go/neo/proto: Introduce Encoding · c0d54d50
      Kirill Smelkov authored
      Encoding specifies a way to encode/decode NEO messages and packets.
      Current way of how messages were encoded is called to be 'N' encoding.
      
      This patch:
      
      - adds proto.Encoding type
      - changes MsgEncode and MsgDecode to be methods of Encoding
      - renames thigs that are specific to 'N' encoding to have 'N' suffix
      - changes tests to run a testcase agains vector of provided encodings.
        That vector is currently only ['N'].

      And provide only single top-level entry-points to encode/decode
      messages. As of now the entry points are just plain forwarding, but with
      introducing of msgpack and encodings, they will take into account
      through which encoding a message has to be encoded/decoded.

      - Regrouping messages would change their message codes, thus introducing
        backward compatibility breakage.
      
      - The protocol itself is currently kind-of documented in separate
        document here:
