hi... got a crash when placeing a sign (!!) in cargodist r18625

crash.* and the most recent autosave...

ps. to load it you probably gonna need a nightly of the 2cc set, or from one of the last posts in the 2cc dev thread

Every sign? Or only sometimes when you are building signs? And does it crash when you doesn't use 2cc? And why you are using this "old" version?

Sincerely

Thanks. Unfortunately I can't reproduce it and the crash dump gives me a corrupted backtrace. However, I'm missing the exact version of the dutch tram set grf you're using which might be the reason I'm unable to reproduce the problem (I have a different version which is also called "release candidate 1"). Could you send it to me?

In the crash log it says it's an assertion failure in LoadUnloadVehicle. Thus the crash should be deterministic unless something is seriously wrong. Did anyone see any desyncs with cargodist lately?

Could you please post an earlier savegame? The crash seems to come from the AI system. Which versions of which AIs are you using? Did you change anything about the setup during the game? Did the game crash for the other player, too?

After lots of help from fonso, I got my first git-checked-out game running!

Roelmb · Post by **Roelmb** » 10 Jan 2010 05:48

Was it that difficult petert to get the git? I do it with tortoisegit.
I'm already trying to get other patches on it. For a new GD patch xD.

and can somebody look at the trafficlights patch? It crashes when patched too the latest cargodist. I think it was crashing in the trafficlights.h file but I'm not sure need to check that.

and at the moment I can't check it (not at home)

Okay, we are using the dummy AI because I forget to disable the AIs

Now we are playing with four players

And a recent save is only a yearly autosave... I'm searching for it.

Hello,
okay here is the autosave from 1. Jan 1942 just before the game crashs. But before I'm uploading it, I want to know, if the rcon-Password is saved in the savefile.

ehr... The password was bad so no problem if I maybe publish it here now

Sincerely

I can obtain the source, that's fine. But when compiling, MSYS didn't know the "git" command, so there was no version number after it was done compiling.

Then install it. Just like you can install unix2dos if it's not there, or zip, or ...
It's done by the compile farm in MSYS, so you must be able to do the same.

petert · Post by **petert** » 10 Jan 2010 15:36

Hi again,
That previous screenshot, that was compiled with MSYS, and it worked. But when compiling with MSVC and opening openttd.exe, the title is called "OpenTTD norev000". Is there a way to make MSVC recognize git?

Post by **Rubidium** » 10 Jan 2010 16:01

Maybe something like adding it to the global path? Anyway, it works for the compile farm, so you should be able to get it to work too.

xZise · Post by **xZise** » 10 Jan 2010 19:41

And there was another crash (not my computer). Unfortunately the most recent save is from 1,7 years before

Sincerely

Thank you so much, Rubidium. It works like a charm. Here is a new binary, g8b866db7-cargodist.

Disclaimer:
If CargoDist crashes, do not report it to the OpenTTD developers. Report it to this thread. When making your post about the crash, please upload the crash.dmp, crash.log, crash.sav, and crash.png (only available as of r18184, so if you are using a build older than that, don't bother). These files are vital to finding what happened during the crash. For developers, you can find the PDB file and other files at this site: http://users.tt-forums.net/petert/dev/

Fonso, I must once again commend you for your excellent work, but I have a couple of questions/suggestions:

1) If deemed mature and stable, would Cargo Dist be added to trunk? What I mean is, do devs reject Cargo Dist on principal?

2) How about a feature where demand to a station is increased if there are more destinations from that station? So major hub stations would be more popular than end of line services, even if the cities are equally sized.

3) I know that when a passenger reaches his destination money is deducted to make the overall fare as if it had been one, direct route. What I'm wondering is that is time spent waiting at a station factored into the equation? So if a passenger has to wait in a station for a long time, does that reduce how much money you get?

Thanks,
Wasila

EDIT: Read original post and realised something: is 2) already on the to-do list?

bokkie · Post by **bokkie** » 10 Jan 2010 23:15

excellent work indeed!

I'm not Fonso (or a dev) but this is what I think/know:

1) Probably. Devs seem to like a cargodist-type feature. This because Celestar (dev) started a similar patch a while ago, but didn't finish it. It might be that devs don't like the current implementation, but I haven't seen any objects yet. Problem is, 'mature' and 'stable' is pretty hard to achieve with such a large patch. Thoroughly testing by users is very important, and there must be a dev willing to review the code after that. It's the question whether there's a dev interested enough with enough spare time to do this. Possible problems I see before trunk inclusion are
- somewhat unclear options (mind you, I know what they do but new users probably don't at first sight)
- unexpected behavior for some people when not using non-stop orders. People are warned for this in-program, but I can imagine devs wanting a more elegant solution.
- slowness in some situations (don't know exactly but sometimes a lot of calculations have to be done for the link graph I believe. There were some posts by people surprised by that.)
This is just me guessing though, I don't really have a clue

.

2) The to-do list includes a plan to increase the number of created passengers when more destinations can be reached. This isn't what you mean. What you want, isn't that already implemented? More people travel via the station with more destinations simply because people wanting to those destinations, pass the major hub.

3) Isn't factored in as far as I know. This is regular OpenTTD behavior.

Wasila · Post by **Wasila** » 11 Jan 2010 10:46

If Cargo Distribution was ever implemented into trunk I'd assume an on/off feature and when on there would be no need for non-stop orders - they would automatically be so?

I see what you mean about 2)... it is already going to be naturally more popular.

EDIT: One more thing: when on a train's cargo information it says for each wagon 'x passengers from <station x>'. Is this just where the majority of people on that wagon are from? I assume that the cargo distribution is not limited to wagon blocks?

fonso · Post by **fonso** » 11 Jan 2010 12:12

There is an on/off switch. Set the demand function to "unhandled" for all cargo and you don't get any cargodist. The cargo shown in the train cargo information is about the first cargo packet in the waggon. It doesn't say anything about quantities. This is a problem of trunk, though. You don't need cargodist to load packets of different origins into one vehicle.

Kogut · Post by **Kogut** » 11 Jan 2010 14:44

About warning... It is possible to improve it - from "it is BAD idea" to "non-stop orders are required by cargodist to work"

fonso · Post by **fonso** » 11 Jan 2010 15:24

They aren't required. In special cases you might want a nondeterministic order. Cargodist just behaves differently if you use nondeterministic orders.

hi anybody

what about binnary with cargodest and infrastructure sharing (http://www.tt-forums.net/viewtopic.php?f=33&t=42254) for win32 (and maybe linux for server)? must i compile it by myself? (it is not so easy for me)

edit: later i found one try at http://new.tt-forums.net/viewtopic.php? ... s&start=20
i hope it is more stable than they said
