Crash on exit

[Vladki]

I have updated the testing server to latest exicutable and pakset. Simutrans now crashes when I want to quit the online game, with the following output:

FATAL ERROR: vector_tpl<T>::[] - 20transferring_cargo_t: index out of bounds: 0 not in 0..4294967295

Next start says that the savegame is corrupted, and the second start gives me the demo game. Exiting and starting form the demo game works fine.

I am having trouble reproducing this because I get a crash deep in the networking code whenever I try to connect. This specific crash I have been told relates to a bug from Standard that only usually arises when there is a desync.

I have, however, fixed a bug related to disconnecting from network games. Can you re-test?

[Vladki]

It is still the same. I get a desyc sometimes, (due to interference on wi-fi), but it does not crash on desync. I reconnected to wifi on different channel to get rid of desyncs, but the crash on exit is still there.

[jamespetts]

Can you upload the saved game so that I can see whether I can isolate the problem from the crash on desync issue?

[Vladki]

Well, when I switch to better connection, I do not get the

FATAL ERROR: vector_tpl<T>::[] - 20transferring_cargo_t: index out of bounds: 0 not in 0..4294967295 on exit. However with bad connection (2.4 GHz wifi) I get that even with fresh game (server.exp.simutrans.com:13354) http://server.exp.simutrans.com/debug-saves/svenska.sve (pak128.sweden-ex)

After disconnecting from more developed game, I get one more crash on next start saying

FATAL ERROR: loadsave_t::read - savegame corrupt, not enough data
. While debugging other crashes, I found out that I cannot save a server game, even with good connection - again the same error.

Edit: now I got the same error on exit even on my better connection...

[jamespetts]

I think that I have managed to fix this; would you be able to re-test? I should be most grateful.

[Vladki]

Seems to be OK.

Are the server.exp.sim... running the latest build now?

[Vladki]

not yet
Edit: now it is updated

[Ves]

Remember to save the map when you update!

Sorry, forgot... But there is a setting .server_save_game_on_quit = 1
hmm let's see if it works

[Ves]

Dont worry. I was working on the map however, so suddently I got disconnected
Lets try that setting and see if it works!

edit
And now it does not crash when closing down either!
