Nicky21 Posted October 31, 2018 Share Posted October 31, 2018 What do i need to change in what files so that when i scale up the Extraplanetary Launchapds workshops using tweakscale its productivity scales appropriately? Quote Link to comment Share on other sites More sharing options...
TranceaddicT Posted October 31, 2018 Share Posted October 31, 2018 So here is something I was investigating that I find interesting. You'll notice in all the DRE errors you have 'TweakScale.PrefabDryCostWriter+<WriteDryCost>d__4.MoveNext ()'. I found this explanation for the MoveNext prefix: The d__4 portion is a prefix that is generated by the C# compiler to keep the construct unique from other generated members / types. In this case the d prefix means that it is an iterator or async method generated class (d is used for both). The number is just incremented for every name that is generated. Is this a thing since the d__# never increments? (Note: I have ZERO experience with C#.) Quote Link to comment Share on other sites More sharing options...

I tried KSP 1.4.5 + TweakScale + TweakableEverything + Deadly Reentry + "MM /L Experimental" and the test KSP capsized before even finishing the load! By deleting TweakableEverything, KSP managed to finish loading and I could confirm the behaviour. But, and I want to make this absolutely clear, TweakableEverything was working absolutely fine on the previous testings (Impossible Innovations + B9 + AirplanePlus). "My" /L Experimental fork for MM has a kind of a weakness that I'm exploiting to check the DLLs health: due being fired up early on KSP load chain, and due relying on KSPe services (that constantly probe all the loaded DLLs by Reflection), anything, absolutely anything wrong on any, absolutely any DLL blows up everything. So, I have an early and screaming notice of something that would silently fail later. (this weakness is so useful at the moment that I didn't bothered to fix it yet! ) By coincidence, or not, this Exception are repeated ad nauseam until the bitter end: [EXC 20:52:09.573] ReflectionTypeLoadException: The classes in the module cannot be loaded.

Me too. All of this hint me that perhaps I'm chasing ghosts on trying to find an add-on (or set of add-ons) badly incompatible with TweakScale. The problem appears to be not on the Add-On, but on something on the environment where some add-ons bork by stumbling on the very same thing "my" MM stumble (but, being in the critical path of the load process, blows up everything on the act). I know for sure that the absence of a DLL that it's a dependency of another one causes this critical failure on MM /L (frankly, it's a failure on the Mono's VM by leaving its internal data structures in a inconsistent state, but whatever - it's me the one that have to workaround it). So, I'm guessing that, in reality, we are facing some kind of dynamic linking problem. And such linking problem is tampering the add ons that relies on Reflection.

FreeThinker Posted November 1, 2018 Share Posted November 1, 2018 (edited) @Lisias One part which could defiantly use a tweakscale fix is the RoveMax Model XL3. The problem is that whenever you try to scale it up, it no longer can properly turn. My first guess is that a tweakscaleconfig should be added for ModuleWheelMotorSteering and scale steeringTorque with exponent 2 Edited November 1, 2018 by FreeThinker Quote Link to comment Share on other sites More sharing options...

Dude… I should had paid more attention to your post. Imagine the following scenario: TweakScale V-1 generated a code. Then some revisions later, the synthetic methods are generated in a different order or whatever. As long such synthetic methods are used only by the current DLL, no problem - but if by some reason such methods are not "internal" to the DLL, and other DLLs manage to link against them, then we have chaos - clients calling one thing thinking it's other completely different. It's a looong shot to imagine that such mishap would had been allowed to leak - but… I already saw some problems being solved by merely recompiling the thing, so…. I think I'm going to start another recompile fest tonight.

Lisias Posted November 1, 2018 Author Share Posted November 1, 2018 (edited) The kerbalEVA* issue that happens with HulcamVDS , doesn't happen on a identically installment on KSP 1.4.1 - I literally copied the MODs from 1.4.5/GameData to 1.4.1/GameData - being the only difference the Squad's folder (of course) and the absence of the SquadExpansion folder. DeaflyReentry, however, blew up on millions of colours - but I put that on the "no supported version" basket. Not an issue. So I decided to test KSP 1.4.5 with and without SquadExpansion, and got the very same results: NREs on kerbalEVA. But at least, I know have a hint: it's a problem between KSP itself and some mods (not TweakScake). — POST — EDIT — Test done. No news. Same behaviour. ``` [ERR 20:52:15.960] [TweakScale] Exception on kerbalEVAfemale.prefab.Modules.Contains: System.NullReferenceException: Object reference not set to an instance of an object at PartModuleList.Contains (Int32 classID) [0x00000] in <filename unknown>:0 at PartModuleList.Contains (System.String className) [0x00000] in <filename unknown>:0 at TweakScale.PrefabDryCostWriter+<WriteDryCost>d__4.MoveNext () [0x00000] in <filename unknown>:0 ``` This happens on KSP 1.4.3, but not on KSP 1.4.1.

Since the nasty collateral effects are being echoed by all the game, the getPartInfoByName appears to be working, and so the real problem is that kerbalEVAs doesn't have a prefab anymore, or perhaps we have a race condition where tow modules (and I include Squad's on the basket) are concurrently changing that part. — POST — EDIT -- I killed some day job and did MOAR TESTS on the subject.

A "race condition" is when two somethings try to access the same something else, and nobody knows what happens because no one knows who will hit that something else first - being the reason we call it "race condition". If A hits the thing first, you have a result. If B hits it first, you have another result. But only one of that results are the right one, and there's nothing ensuring that the right one hits that thing first. It's a concurrency problem. Interesting enough, one of the technics we use to solve this is called "Semaphore", where we can assure that only one will have the green light to hit the disputed thing and, so, we can ensure the right result.

But it appears to be irrelevant to the problem, as it's happening with or without the vintage kerbals. The problem is happening when trying to add a new Module to the kerbalEVA. Something changed somewhere, and the loading of the Module is raising an exception that it's borking the PartModule.Load method - and this method leaves the GameDatabase''s entry for that kerbal part in a inconsistent state (being more specific, with a nice NULL on the atribute that should have a list of ConfigNodes, each one pointing to a module). Then, later, some other code (as TweakScale) will bork marvelously because there are never a NULL on the module's list of a part, at the worst, an empty list. And since there're never a NULL there, we never check. And since it's a list of something (modules in this case), it's usually used on a foreach - being the reason that it's usual to see a MoveNext call on the stack dump.

First, don't use the for each unless it's in a Start or Awake. Use a for loop with integer using the length of the list, it's faster. Second, I always check for nulls in parts list these days because for whatever reason I am occasionaly seeing a nolle in the parts list and it's safer to check and be able to ignore it then not check and have an exception.
