Bit 1: * When exceptions happen in trying to deserialize a table row by index, it now includes the field name properly. This will help fixing exceptions in those serialization areas. |
|
|
* Added three more canaries that are network-only, these ones into hacking events, so that we can identify if there is a problem with them. |
|
|
* Added another canary around the active hacking event on entities, again only for multiplayer. Code review seemed fine, so narrowing it down even further seems needed. |
|
|
* Put in some extra paranoid canaries, for the network only, surrounding each kind of external data. That way if a specific mod or subfaction or whatever has a serialization issue, it will become apparent which one it was. |

Okay, I can hit these canaries!! |

HUGE thanks for this report! * Fixed a super longstanding MP issue that has become more prominent recently, but has been hiding in plain sight basically since the start, breaking ship sync intermittently and also causing some other issues. ** Essentially, on MP clients it would not properly say "I finished my current hack" on ships that were hacking. This led to situations where it tried to deserialize nonexistent hacking event data on the hacker every time the host would send it new data, which would then lead to serialization failures and in general a long and continual divergence in the simulations. ** However, this was something that would fix itself on disconnect or reconnect, or save and reload, so that made this super extra hard to find. Until recently, it was also not clear that this was related to hacking events, because without the new density of canaries we didn't find out things were wrong until long enough after a hack finished that they didn't seem correlated to anyone. ** This was surely a cause for various other UI and behavior problems on clients, such as likely inability to do more hacks with that hacker, and other things of that sort. ** We have verified the fix, and knock on wood let's hope this is the last of the mystery sync issues! |
