      go/neo/proto: Sync with NEO/py on changes to make the number of replicas modifiable at runtime · 0d75e144
      Kirill Smelkov authored
      This corresponds to NEO/py commit ef5fc508 (Make the number of replicas
      modifiable when the cluster is running).
      
      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).

      go/zodb/zeo: Skip handshake/py/msgpack=true on ZEO4 · 6d9a8046

      ZEO4 does not have msgpack support and does not take $ZEO_MSGPACK into
      account. With ZEO4 this test was failing before:
      
      	--- FAIL: TestHandshake (0.46s)

      	        zeo_test.go:241: handshake: encoding=Z  ; want M
      
      We don't have infrastructure to check python packages versions, so
      check it by verifying ZEO.asyncio presence.

      go/zodb/zeo: MsgPack support · 63d322b9
      Kirill Smelkov authored
      ZEO5 adds way for messages to be encoded via either pickles or MessagePack.
      However until now we were always using pickles.
      Let's add msgpack support to be able to e.g. use wire encoding that
      server prefers.
      
      MsgPack support is almost fully localized in encoding.
      We use tinylib/msgp runtime routines to decode/encode msg fields with known types,
      and shamaton/msgpack to decode/encode msg.arg, which is interface{},
      because msgp does not generally work for arbitrary reflections.
      
      For msgpack=true, tests state is the same as with pickles: handshake
      works, but load fails when verifying that Load returns correct error for
      deleted object:

      go/zodb/zeo: Accept both int|bool for pickled message flags · f7543195
      Kirill Smelkov authored
      It is already documented in pktDecodeZ comment that flags is int|bool.
      However until now we were decoding it only as int.
      
      As is it was working, but it will fail when receiving e.g.
      invalidateTransaction message, because ZEO/py server actually uses bool
      when sending it:
      
          https://github.com/zopefoundation/ZEO/blob/5.2.1-20-gcb26281d/src/ZEO/asyncio/base.py#L139
      
      Fix it.
      This will be covered by watch tests, when watch support will be added in a followup patch.

      go/zodb/zeo: Introduce notion of encoding · 0696cd64
      Kirill Smelkov authored
      Keep information about which message encoding is used on the wire in
      encoding type. Make pktDecode/pktEncode and data type conversion
      utilities be methods of this type. For now there is only 'pickles'
      encoding, but we'll soon introduce 'msgpack'.
      
      Currently not everything related to pickles is localized in encoding -
      we'll be moving more bits to encoding in the followup patches.
