Bugs, terrestrial arthropods with at least six legs. Sometimes we don't notice them, sometimes we ignore them, but they do exist and there are times when they need to be dealt with in one way or another. Most of the bugs fixed in this release have a little less legs than proper insects, they're far from being as critical as the ones fixed in the previous release and yet we consider them annoying enough to warrant this new version of NeoGo to be published. We don't want to see our users fighting these pesky creatures in the wild, better update and have a troublefree experience.

If you're not affected by #2815 (requests for verbose transaction data and application logs failed for some specific mainnet transaction(s)) you may leave the DB as is with this upgrade, if you want it to be solved then please resynchronize.

Behaviour changes:

  • "loadtx" VM CLI command now uses transaction system fee value as the default GAS limit for the context, unless --gas is used (previously it wasn't limited, #2816)
  • SendRawTransaction RPC client method will now always return transaction hash, even if error occured, this also affects Actor APIs and allows to handle some specific errors (like transaction already present in the mempool) in more appropriate way (#2817)
  • Actor and NotaryActor Wait() wrapper methods now handle "already exists" and "already on chain" errors as non-errors, waiting (if needed) and returning proper results (#2817)

Improvements:

  • reworked network discoverer/connection manager that has a better picture of the network (especially if it's a small one), doesn't try to make additional connections (even when having less than MinPeers of them) when there are no more real addresses to connect to, establishes stable connections faster in containerized environments and does more connection attempts when MinPeers setting is not satisfied, but there are potential candidates (#2811)
  • VM invocation stack handling microoptimization (#2812)
  • load* VM CLI commands now accept --gas parameter to set the amount of GAS to be used in this context (#2816)
  • better logging during state reset process (#2813)
  • subscription-based transaction waiter now handles already accepted transactions faster (~immediately vs waiting for block timeout previously, #2817)
  • WSClient can return more specific error on websocket handshake failure if it's provided by server (#2821)
  • new MaxWebSocketClients configuration option for the RPC server to control the number of allowed websocket clients, missing or 0 value make the server use the default of 64 which is compatible with the previous behavior (you can use old configurations if you don't care about this option, #2821)

Bugs fixed:

  • occasional "loadgo" VM CLI test failures because of timeout (#2810)
  • websocket waiter test instability (#2809)
  • websocket event unsubscriptions could lead to node deadlock in rare circumstances (#2809)
  • exception handler could use improper evaluation stack in some cases (#2812)
  • pointer stack items were not handled correctly in "protected" serialization mode leading to inability to deserialize these items back (#2816)
  • state reset functionality not working for big chains like mainnet (#2813)
