      go/neo/neonet: tests: Introduce T · 41a120c1
      Kirill Smelkov authored
      This represents a neonet testing environment and in the future will be
      used to run tests under different protocol versions, protocol encodings, etc.
      
      For now it is noop wrapper around testing.T + t.bin that wraps []byte
      and will be amended to return something different depending on t's
      encoding.

      go/neo/neonet: Rework handshake to differentiate client and server parts · e407f725
      Kirill Smelkov authored
      Previously we were doing handshake symmetrically: both client and server
      were transmitting hello and receiving peer's hello simultaneously.
      However this does not allow server to adjust its behaviour depending on
      which client (protocol version, protocol encoding, ...) is connecting to it.
      
      -> Rework handshake so that client always sends its hello first, and
      only then the server side replies. This matches actual NEO/py behaviour:
      
      https://lab.nexedi.com/nexedi/neoppod/blob/v1.12-67-g261dd4b4/neo/lib/connector.py#L293-294
      
      even though the "NEO protocol" states that
      
      	Handshake transmissions are not ordered with respect to each other and can go in parallel.
      
      	( https://neo.nexedi.com/P-NEO-Protocol.Specification.2019?portal_skin=CI_slideshow#/9/2 )
      
      If I recall correctly that sentence was authored by me in 2018 based on
      previous understanding of should-be full symmetry in-between client and
      server.
      
      However soon we are going to teach server sides to autodetect client
      encoding and adjust server to talk to client via its preferred way.
      This needs handshake for client and server to be differentiated.
      
      The protocol needs to be adjusted as well. However I'm not sure it is
      going to happen...

      go/neo/neonet: Fix thinko in recvPkt · 4f6adb26
      Kirill Smelkov authored
      We were returning packet with tail read for next packet data.
      Previously decoding was forgiving, but upcoming rework for msgpack
      support will add check to catch packets with overlong payload, e.g.

      -> Fix is: pkt.data should be data[:pktLen], not data[:n] since n is how
      much we have read at all.

      For ZEO it is not strictly required, but for upcoming NEO for example
      NEOCluster needs to shutdown gracefully, else there are processes left for e.g.

      Kirill Smelkov authored
      We recently hit "decode: buffer overflow" errors due to mismatch in
      between NEO/go and NEO/py (see previous patch). With dumpio=true that
      problem was showing itself as

      Here after printing error and dumping all bytes from packet payload, it

      fixup! go/neo/proto: Switch enum encoding from int32 to int8 · 05463172
      Kirill Smelkov authored
      In commit 5f13cc85 I changed enum encodings from int32 to int8, but did
      not noticed that NEO/py commit 52db5607 ("protocol: a single byte is
      more than enough to encode enums") despite specified intent and
      ErrorCodes being marked with @Enum, changed encoding only for fields
      that are marked as PEnum in structures. In NEO/py the Error.code field
      is still marked as PNumber which encodes as 32-bit integer on the wire.
      -> Fix it back.
      
      With recent xtesting.DrvTestLoad update this error was manifesting itself as (on @t branch):

      This corresponds to NEO/py commit ef5fc508 (Make the number of replicas

      One important change in the protocol is that Client no longer queries
      Master for partition table - instead M pushed partTab to C right after
      identification (after pushing nodeTab).
