New map features

[Hafting]

Another crash report. I just built a new ship, and was setting up its route & re-fits:

Pause the game
Make a depot in the middle of the sea (not realistic, but ideal for this route)
Buy a ship, bring up the order list
Create a farm pier
Click the farm pier, order the ship to re-fit to milk and wait for a full load.
I'm rich at this stage, so build a canal so the ship can deliver to the dairy (no need to set up milk trucks then)
Go via a depot and some buyos, due to the distance
Deliver the milk at the dairy pier
Go to "Seltinden havn" (older combined railroad & harbour station) where I want my ship to fetch farming supplies for the return trip
Click the refit button, and the game immediately dies in a segmantation fault!

I guess this is a "rare" sort of crash, for I have several combined rail/harbour stations, all with lots of refits for ships & trains
Or is it a problem building some of the destinations in between adding orders to an open order window?

I could restart the game, complete the orders and start the ship on its route. Whatever it was, it doesn't happen every time I try this.

*** End of OpenTTD Crash Report ***

The crash I just reported is repeatable, which probably makes it easier to fix.

Crash recipe:
1. Load the attached savegame. It should come up paused.
2. Click the ship depot a little south to the airport/harbour labeled "Fosnavåg Raffineri". It should contain the newly bought "ship 73"
3. Click "ship 73", bring up its order list
4. Click "go to" the pier "Lørenskog kornbruk".
5. Notice that now, the game is ready for me to pick more destinations for the ship. If I want a re-fit, I should select the correct order line, because the active line is the " - - end of order - -" marker. But if I try to re-fit without selecting the correct line, the game crashes. Looks like a missing check - the attempt to build a re-fit menu for a line after the last order line seems to be the killer.

I have done some more checking, and it looks like asking for a re-fit without selecting a line - or explicitly selecting the "- - end of order - -" line, will kill the game on every attempt. At least when I use the last ship built.
This is hopefully easy to avoid. The most user-friendly action is probably to create a re-fit order for the last refit-able line. That is usually what the player intends, when making a series of destinations and suddenly a re-fit. But simply graying out the re-fit button when "- - end of order - -" is active is good enough to avoid this crash.

Thanks for your bug report. The refit button in the orders window for an aircraft or a ship was not being disabled when no order was selected or when refitting did not make sense for the selected order. I have just pushed a fix for this.

I have just pushed a fix for this.

Here is the unguaranteed Windows 32 bit binary ...

And here is the ubuntu version.

Hello! I want to report crash on game.
Situation: two trains have different speed passing through tunnel with signal simultaneously occur Floating point exception.
I'm using Ubuntu 14.10 64bit and cloned your fork and compile using gcc.
Below attachments are log and save file. I'll give more information if you need
Thanks

[TrueSatan]

my mistake, was an old crash log

[cirdan]

Situation: two trains have different speed passing through tunnel with signal simultaneously occur Floating point exception.

Thanks for your report. The crash was a division by zero when the rear engine of a dual-headed train partially into a tunnel and stuck behind another, slower train tried to produce a spark. I have just pushed an update to the repo that should fix this.

Tried to load the crash savegame and got a crash as well. Missing only a few graphics, guess they don't matter.
[snip]
Maybe it helps for finding the bug Cirdan.

Your crash happens at a different place, so it seems unrelated to the other one. Were you doing something when it crashed, like placing rail (that is what the stacktrace suggests)? Could you recheck and report back if the crash persists with today's snapshot?

Funny thing, I only loaded the crash.sav provided by arsenlupin. Nothing more nothing less, I couldn't even do anything it crashed immediately.
I will check if it happens again. Maybe there is something else fishy in his save game.
Edit: oopsy it was the wrong crashlog. Nevermind. Game still crashes though but maybeIt was because of the missing graphic files. With trains in NML
the game runs.

Thanks for the fast bugfix
Compiled for Ubuntu 14.04 64bit as usual.

Cheers

[arsenlupin]

Thank you for lightening-fast commit
I've pulled and compiled on Ubuntu 15.04, there was no crash or bug on 6+ hours play.

By the way, is there someone having trouble with compiling using make with file not found error of <tr1/memory> on OS X Yosemite?
Tried troubleshooting guide for Mavericks on https://wiki.openttd.org/Compiling_on_Mac_OS_X but it just resolves some warnings.

Code: Select all

[LANG] Compiling strgen/strgen_base.cpp
In file included from /Users/***/workspace/fttd/src/strgen/strgen_base.cpp:14:
/Users/***/workspace/fttd/src/strgen/../core/pointer.h:35:12: fatal error: 
      'tr1/memory' file not found
#  include <tr1/memory>
           ^
1 error generated.
make[1]: *** [strgen_base.o] Error 1
make: *** [all] Error 1

[cirdan]

That error is related to the detection of smart pointer classes. The code requires at least an implementation of a shared pointer in the library. Now, while most (all?) supported compilers have a working shared_ptr somewhere, the problem is finding it: the canonical place is namespace std in header <memory>, but sometimes the namespace is std::tr1 and sometimes the header is <tr1/memory>, and these two do not always come together. So I use a simple static heuristic at compile time that checks for compiler type and version, which seems to fail in your case. What compiler are you using?

You can also try to tweak the checks for your particular case yourself. In file src/core/pointer.h, delete lines 27 to 56 and substitute this:

Code: Select all

#include <memory>
#define ttd_shared_ptr std::shared_ptr
#define ttd_unique_ptr ttd_shared_ptr
#define TTD_UNIQUE_PTR_USABLE 0

Try replacing <memory> in the first line by <tr1/memory> and/or std::shared_ptr in the second line by std::tr1::shared_ptr until it compiles. If none of the four combinations works, then I would very much like to hear about your setup. If one of those combinations does work, you will get a working binary (barring other errors, of course), and you can further fine-tune your compilation by replacing ttd_shared_ptr in the third line by std::unique_ptr and, if that succeeds, by setting TTD_UNIQUE_PTR_USABLE to 1 in the last line. These two changes should reduce pointer overhead if you have a fully working C++11 environment.

Crash report

Seeing congestion, I tried to optimize my railway a bit. Some trains don't use the depot shown in the crash image, so I was building a line with less corners. Fast trains will not slow down so much, or so is the theory.To connect the line, I had to remove a signal. You can see the cursor in the screen dump - ctrl-clicking the tile crashed my game.

I can only guess that this is something about "removing a signal with a moving train on top, with the other end of the train inside a depot" ?

Unlike first report, infrastructure on map is too much, so I cannot specify the situation make crash.
I'll upload extra information if you need.

I found the situation via debugging.
On train_cmd.cpp, function TrainEnter_Track restricts the slope least than 3. But ground slope of newly lay rail track on edge of bridge was 8, so it make assertion failure.

I've modify assertion condition to 9 it makes not crash anymore but makes side effect like below screenshot.

this call fails to convert the tile slope (steep slope) into the foundation slope (flat)

Crash report

Seeing congestion, I tried to optimize my railway a bit. Some trains don't use the depot shown in the crash image, so I was building a line with less corners. Fast trains will not slow down so much, or so is the theory.To connect the line, I had to remove a signal. You can see the cursor in the screen dump - ctrl-clicking the tile crashed my game.

Thanks for your bug report.

I can only guess that this is something about "removing a signal with a moving train on top, with the other end of the train inside a depot" ?

Yes, this is giving me no small amount of headaches. But this time I may have found the way to get rid of all these "partially into a depot" bugs. I still have some testing to do, but I should have a fix ready in a few days.

Hello! Set gcc version as 4.9+ just make succeed compile on OS X Yoseimite.
Thank you again!

Glad to help.

But I'm back with new crash report.
It also produced on train_cmd.cpp, same as Hafting.

...although it is a different bug. Yours is something that I missed when I allowed custom bridgeheads on steep slopes. Easy enough to fix, but I will wait until I have the other one fully sorted out. Thank you too!

[cirdan]

I have updated the repository with fixes for the bugs reported last week (crash when removing signals under a train that is partially into a depot, reported by Hafting; crash when using a custom bridge head on a steep tile, reported by arsenlupin).

There is also one new feature. The town window now has a button to show the station influence area for the town, i.e., the area where a station (as represented by its sign tile) contributes to town growth and company rating improvement. In the attached picture, the southern station would help the town grow, but the northern one would not.

I have updated the repository

and here is the Win32 binary ...
Enjoy
