Yes, I got exactly the same assert about capacity of an edge being <= 0 or edge distance being => uint_max, but it was not in the title screen, just a normal game. I haven't any savegames to provide and I didn't try too much to reproduce it, that's why I didn't say anything about it. It happened when I had a small rail network and I built a "leg" to few another towns. One of the stations was placed right between two cities. It didn't even accept passengers AFAIR, so I had to feed it with busses (or rather horses, since it was still 19th century). About right after the first of my "busses" finished his first or second trip around, I got the assert. Oh, the rail station wasn't used yet, there was no trains going to it.

I don't know if it helps at all, but here is the situation (Wrundton Woods is the first station in the list of orders):

So, I'm fairly sure there is a desync in this patch pack. Otherwise the assertion should be happening for everyone at roughly the same time.

I assume this is the win32 build? Running on what version of windows, or perhaps wine?

fonso wrote:What bothers me a little is that it doesn't happen to me. That sounds like desync. Do you have a special title game there? Is there anyone who also gets the same problem? Or rather, is there anyone besides me who doesn't get it?

In the title savegame, it's the one of the mail links dropping down to zero. Since this only happens on the linkgraph calculation interval, and only when the moving average is short enough that the vehicle breaks down (?) and can't complete a trip within that time, it's depenent on the length of those settings. And the length of those settings is dependent on the daylength setting...

Hence, by default, it won't show up on the title screen unless you wait around long enough, and that "long enough" depends on your setting for linkgraph, moving average and daylength.

In any case, I can reproduce this with a vanilla cargodist build as well.

Well, difficult to say... it would require more testing. It does seem a little indeterminate in that it can happen at different times, but at least with a quick localhost-server-client test, the assertion happens at exactly at the same time (within degree of measuring accuracy).

Yes, you're probably right. I was too fast with my conclusion.

Test this again with a post-r18934 build once it comes.

Has anybody else problems with loading savegames? In 95% of all tests the game crashes during loading.

Please provide the crash files, even when reporting something as trivial as this.

Same here, will post them when I've got time

Here it ist.

Posted: **28 Jan 2010 21:44**

Do you have a crash.dmp, or crash.png? I'm not sure if those are generated during a save game crash.

Posted: **28 Jan 2010 23:35**

peebee wrote:Here it ist.

Unfortunately with that kind of crash, the .log doesn't tell you very much (although apparently, this was a savegame from OpenTTD 0.6? And NewGRFs were added in?). I'll need the crash.dmp, and preferrably the .sav that you're loading as well.

If the forum doesn't let you attach those due to file extension restrictions, rename them to something else.

I haven't been able to reproduce any errors-loading-savegame myself... but unfortunately, I don't have very much material to test with either

Posted: **29 Jan 2010 01:52**

I've been having the same crashes with loading saves. I've disabled my newgrfs and i'm just using an empty random generated map allowed to play for a couple days; I've attached the log, the dump log, and the save in question.

Let me know if you need anything else, and thanks for the patches

Posted: **29 Jan 2010 15:22**

Thanks for the .sav, I was able to reproduce it.

I've traced this down to a bug in the cargodist saveload code, it seems to corrupt GlobalCargoAcceptance by loading an UINT[32] array into a *pointer* to an UINT[32] array (32-64 bits...), which doesn't quite fit.

I'll wait for fonso to fix this.

Obsolete: New build here.

First, thanks to SpComb, fonso and all the others who contributed to this patch. It's finally the TTD I always wanted (from 1995 onwards)!

This is a binary Linux build for Ubuntu 9.10 (Karmic Koala), based on the patch above (r18948).

GCC version: 4.4.1 (Ubuntu 4.4.1-4ubuntu9)
--enable-debug and --enable-profiling not used since they reduced performance to a slideshow even at the title screen.
Debug symbols are still in the binary, i.e. not stripped.

Download:openttd_cargodist_minipack_1_0_svn-r18948-no-debug-unstripped_i386_deb (16MB)
Note: This build hangs for me on a futex lock if I try to quit through the menu (either in-game or from the title screen), but quitting by using the window-manager decoration does work. If it hangs for you, kill it with

Code: Select all

killall -9 openttd

in a terminal.
Edit: Ignore that. Either run the game with "SDL_AUDIODRIVER=pulse" prepended on the command line, or install the libsdl1.2debian-pulseaudio package.

I built this by following the guide on the wiki for Debian-based systems. If I have done anything wrong like having to use --enable-profiling so that the bug reports are useful, please let me know.

And the obligatory:

Likely has something to do with SDL & PulseAudio, see known-bugs.txt for a solution.

Yes, that was it.

Running it with

Code: Select all

SDL_AUDIODRIVER=pulse openttd

fixes the problem. Thanks!

Hello, after installing the patch I have a small issue with local authorities. Seems like building a road is enough for them to change their mind about my company. Also it takes forever to make the rating go up. Any clue? I'm playing on medium level, without AI and without breakdowns. I use the patch with daylegnth 4 and town growth -2.

Posted: **02 Feb 2010 22:48**

this patch should not touch the behaviour of town rating

town rating generally goes down if you destroy a field with a tree or any town-owned buildings/roads. it increases when you plant a tree to a tile that does not already have one, or when a vehicle arrives at a station.

there are basically two ways to handle this: i tend to build a tram or bus network in the city before planning my train station, other people destroy all trees around the town [if your rating is already low, it can't decrease anymore] and rebuild them afterwards.

There shouldn't be any direct effect on how clearing a tile affects the LA rating, at least not that I can see.

nuNce wrote:Also it takes forever to make the rating go up. Any clue? I'm playing on medium level, without AI and without breakdowns.

This, however, is presumably true, since the gradual ratings-growth over time is done per-month - so this happens less often.

Town growth or town cargo, I assume you meant the later?
