| Summary | 0026202: MP client errors jan 29 | ||||

Also, units had a tendency to jump back in time. So they'd appear on a planet, be there for 10 seconds, then jump back to their previous planet and arrive again. It was quite odd. We were playing on 2.5x speed and at like 300 AIP |

Thanks! * The "Found PKID in central list and planetFaction list, but the status in the central list is [whatever]" is now no longer an error at all. It just fixes any data that it finds. |
|
|
Thanks! * In the event that sim repair can't add an entity that is in the central registry to the planet faction list for some reason, repeatedly, then it deletes the squad from the central registry. This pretty much only happens on MP clients. The host should then detect the missing unit and send an update, now that it's not in the central registry. |
|
|
Thanks! * If a ship is malformed in the number of systems it has (this is mostly an MP client thing), it now should fix that rather than complaining about it. It will still complain about it if it just absolutely can't fix it, so we'll see what happens. |

|
Thanks! * The "Found PKID in planetfaction lists but and central lists BUT it was null in the central registry" error should no longer happen (knock on wood), because it should be reassigning in and fixing that data. |

Thanks! * One of the characteristics of "reliable UDP" is that messages will get to the destination, and be in the proper order, but that does not mean it will get there in a timely fashion. Packet fragmentation or other network conditions can create quite large delays. When it comes to ship sync data, if that data is at least 5 game seconds out of date, then it now just junks that information rather than syncing it "back in time." ** It's possible that on a suitably rocky connection, this could lead to a lot of messages being lost. On the client in the full network stats (and on the client in the network stats that get written into your log after playing), it now shows how many data groups of this sort were junked from being slow. |
|
|
More: * Updated the game to use six channels for data (or six ports in the case of Steam Multi-Port). ** There is a new "bulky 3" channel, which is now used just for sending time-sensitive ship information across. This should prevent issues with data for ships arriving really late because of dropped packets, and should reduce lag based on packet fragmentation in general. |
|
|
More: * Changed the MP client asking the host for data about a set of squads to send data in batches of no more than 100 -- it may generate several messages in a single frame by this method, which is fine. ** The idea is to keep this well under the MTU, to prevent any fragmentation, but to at the same time keep it from spamming messages. ** Additionally, in doing this I discovered that previously it was trying to limit it to 300, but really could tack on as many ghost-checks as it wanted, which is why hosts were sometimes hit with "fixed possible runaway loop" errors (I never could figure that out). |
|
|
Final piece for now: * Aside from just sending the ship-sync data via bulky-3, the way that divergence data is sent from hosts to clients is now very different: ** Any deletions are sent as one bulk message. This is another case where it could in theory go over the normal limit of 300 ships at a time, so it no longer has a warning about a possible runaway loop here, either. It really should rarely send so much, but it won't complain for 90k ships now, which is way outside the ever-likely bounds and so should not happen all in one frame. ** For actual ships that have their data being updated, it sends those as individual messages now. These should mostly fit under the average MTU, although it will vary. This should keep network speeds up since we no longer have to worry about fragmentation and reassembly here, and in the event that some packets are misordered, we technically don't even care about that. ** This should make high packet-loss situations a lot more playable, without us having to get into the situation of stale ship data being discarded. |
