Different results on network game

GoogleCodeExporter commented 8 years ago

Hello. I'm cannot say how to reproduce this, but...

Today we play Hedgewars network game (we doing this everyday :)), and at the 
end of game (last turn), two computers show different results of the turn - on 
the one computer last hedge was died due to barrels explosion, but on another 
computer this hedge was flying above barrel, and still alive. And finally, 
network disconnection indicator appear (but network was online, and no any 
disconnects happens (this is 1Gb LAN direct connection, about 3 meters between 
computers)).
If I can help with this, logs, debug, etc - just tell me.
Thanks for your game.

Play on:
Ubuntu 10.10 amd64, updated,  Hedgewars 0.9.13-1
Gentoo ~amd64 updated, Hedgewars 0.9.13

Desync.  In order to debug this, we need ~/.hedgewars/debug0.txt from both 
computers.

What version of fpc was the gentoo version compiled with?

in debug0.txt I've got only this:

Yeah, the debug0.txt needs to be saved *immediately* after the errored game 
otherwise it gets rewritten if you generate a new preview image (clicking on 
the randomising map button) or start a new game.

There's probably a desync, but figuring out the conditions for it are going to 
be harder now.

Can only hope it is rare and taken care of in next release.

One last thing to try (although it might not yield as useful of results).
Do you have demos or saves of that game from both computers?
Hopefully you turned on demo/save timestamping.

If you don't well, that's pretty much it.

Yep, you are right guys, WontFix. This issue was never been repeated more.
Sorry for long answer, and thanks for your time.
