Other weirdnesses.

Sometimes units appear to go to the wrong planet on MP clients. Lets say I have 3 planets in a line like A - B - C. A player whose ships were on B issued a move order to move to planet C. The host saw them moving correctly toward C, but the player reported that visually the ships appeared to go to A.

Also reported: An MP client reported that the planet screen was showing ships from an Allied faction (in this case, the Dyson) as Enemies instead of Allies. This player was playing the Necromancer.

Thanks! As I go:

* Properly fixed that index out of range exception that could still happen on WriteTechThatBenefits(). I was missing a -1 in there.

Back to the first one:

* Fixed some issues where death effect damage may have been overflowing, and in general where it would not serialize if it was negative. Now it just corrects to 0 damage rather than throwing an exception. This was during DeathEffectCausingDamageReceivedToEntity_Data mainly for multiplayer.

The other item was the second one.

Last host one:

* For some strange reason, it was still possible for us to hit Steam's "LimitExceeded" error when sending certain messages that include the entire world file. This was intermittent with clients in general.
** Overall it is true, we were trying to fragment savegames as little as possible, basically breaking them at around 500kb rather than something lower, knowing that Valve's limit on messages is 512k. But with our own headers being around 100 bytes or so, we still should have had plenty of room, so why exactly this was happening is not clear.
** What we've now done is shifted it so that we now target 400kb, which is VASTLY more room than needed. However, in terms of the grand scheme of sending world data, this is really paranoid in a way that should avoid the issue while not letting edge cases slip through. No headers are remotely near 112kb in size, so if we still get the error then this is something to do with how much is queued up in the steam networking buffer or somesuch.
** It's also worth noting that the difference in fragmenting 100kb one way or the other is essentially invisible in terms of performance, and this only affects initial connection.

The two deserializaton errors on client 0 are 100% errors in serialization in general, and I wonder what is happening there. Is that something that is easy to get to repeat? The errors that I'm actually seeing are nonsense, as they are essentially downstream from something else that was deserialized incorrectly.

It's not fast-blast data, which is a bummer, because that would have been my first guess. It's the limited faction sync data, and I am guessing that something in there has a special code branch for multiplayer that is not quite set up consistently, since this is not something affecting other parts of the game in SP. The fact that this was only hit a few times is very curious indeed.

* "CheckForShotAOEDetonation error at debugStage 4100" errors in multiplayer should now be fixed, or if not then it should give an even more specific error now. But knock on wood, should be fixed!

3/27/2021 7:55:50 PM 2.764 CLIENT Called ReadSplitMessage but the FragmentsReadSoFar was 1 and is not one lesss than the messageIndex of 4 that we just tried to append.

Holy @#$@# that's a terrifying message. This is implying... one of two things. Either:

1. Valve's messages are not arriving in an ordered fashion. Things should be way more broken if that's the case.

2. Actually when the four messages were sent and some were rejected on the host, it was one or two of the middle parts, and the first and final parts were both sent. This is actually way more likely, and would fit with the host error (maybe), so in that case this is kind of a non-bug.

But at first glance it looks terrifying. Essentially the host was blocked from sending the middle two fragments by steam, and so the client got parts 1 and 4 and was understandably confused.

Thanks!

* Fixed a "BUG: entityTospawnat is null" on multiplayer clients, but in the process also stopped them from trying to spawn the contents of a wave at all. That was just going to lead to strangeness and lag whenever a wave arrives. That data will be arriving by fast-blast from the host within a matter of milliseconds, and there's nothing for the client to calculate on their own.

Thanks!

* A HandleAutobuild() exception was happening on some multiplayer clients. It probably still will, but it will give way more informative errors now. There's some slight extra protections in there already, but probably not enough for whatever was going on.

Okay... that last line was also highly suspect, hmm. I... don't have a great way to fix this, so it's time to narrow things down with some literal canaries in the code. I have a good idea on how to handle that.

Okay, this is the last of it:

* "Canary code" has been introduced into several of the multiplayer messages. These may be taken back out later, but they really require very little processing and potentially a great amount of clarity, so we'll see.
** Essentially, using our extremely efficient sub-ASCII text encoding, we send a string at certain points in the multiplayer messages, and on the other end it tries to read that exact string. The key point here is that the client KNOWS what it should be receiving. If it receives something other than what it expects, then it will yell right away and throw an exception and stop processing that message.
** When it comes to our serialization format, it is blind and it is without markup or metadata. This is hyper efficient, but when we are reading naked bits... any string of 4 bites can maybe a byte, and any string of 16 bits can make some sort of small integer. We are reliant on clients and hosts knowing exactly what they are reading at any given time, and it's often not until we get a value that is clearly out of range later on that it actually dies. This can be VERY downstream from the actual divergence in data (we could have had 1, 10, 100, or even 1000s of reads that were invalid without knowing it).
** This sort of thing gives us an existential problem in that when we know there's an error in some sort of message, we have no way to know how to narrow it down. The only way to find the divergence is to get the client and the host to both write a log of what they sent, and then diff the two. The problem is always immediately obvious once we do that. However, we have no way of knowing when to log, when the problem is a very intermittent one. Full time logging would make the game unplayable, and we also can't retroactively log after discovering we have a problem (the host never even knows there is a problem).
** The one other way that we can find a problem like this is via manual code review, but that is extremely tedious and we could be looking through literally thousands of lines of code in dozens of files for a single send, since it could involve many external factions or even mods.
** To solve this existential problem, at certain points we can send a known unique series of ASCII characters, which get converted into a hyper-specific series of bits. We're talking about... let's say maybe a series of 72 bits. In the canary check, it would be unimaginably unlikely for all 72 bits to happen to be the right combination of on and off unless the data that has been read prior to now is all exactly correct. Thus we basically cut down dramatically on the amount of code that we have to review in order to find the problem spot, since we don't have logs.
** If the amount of code is still too much, then after the first round of canary checks, we may wind up needing to add more layers of more detailed canaries, potentially that are toggled on as a more lightweight form of message checking, since logs are really impossible to synchronize in a realtime multiplayer game. The data is just too voluminous for players to handle, and they have no way to pre-parse it for our use. The canary solution keeps things brief, to a single line of log code on just the client, and has minimal-to-no slowdown added (if we wind up adding lots of layers of canaries, that would be slowdown, and would be a toggle for when you suspect problems).
** Two things to be aware of with canaries:
*** If I make a mistake when entering a canary, then I may make multiplayer unplayable by accident. That could happen, and would just require a code change to fix it. This is difficult to test in advance of someone else firing up multiplayer, unfortunately.
*** If my canaries are all correct, multiplayer still may become unplayable if there's a bug that a canary is now finding. Essentially, an area of multiplayer might ONLY have been functional because of the nature of "any row of bits is a number," and that in turn would lead to all sorts of strange effects like... well, potentially ships going to the wrong location, or having very mysterious orders, that sort of thing. Those are all just lots of series of numbers, so its entirely plausible to have a functional -- but wrong and fill with lots of sync data request -- multiplayer game going in those circumstances. The canaries would make such a game unplayable, however, because they actually would find at least the general areas of the code and then halt reading of the message (since they know it's garbage after that, even if it's theoretically-playable garbage). This may actually mean a short-term reduction in multiplayer playability, is the bottom line. But it leads to long-term correctness, and the removal of strange MP-specific divergences that wind up sending more and more and more sync data trying and failing to fix itself. Aka over time it will also lead to less bandwidth usage.

Thanks!
