No error message and lost game #199

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. You can look at this game: 
http://ai-contest.com/visualizer.php?game_id=5864984
2. The game stopped at turn 107 with barabanus loss though the victory 
condition isn't achieved and barabanus had much more ships than his adversary.

What is the expected output? What do you see instead?
The game should have been continued. The game stopped instead without any clue 
why the game was lost.

Please provide any additional information below.
There're many games that bots lose without any error message, though they would 
definitely win the game having much more ships than the adversary.

All those games are reported when worker=0

The possible reason could be "not enough memory".
May be the contest rules should be updated with memory use restriction?
My bot sometimes uses up to 38M in the middle of the game.
May be that's why it crashes: not enough memory?

Worker 0 is the main game server, and the others are cloud servers.  At this 
time, only cloud servers do error reporting.  The game end is probably due to a 
timeout.

Here is a patch to add support for error reporting to the trunk engine.  It is 
only part of the solution.

Here is a patch for error reporting in the tournament manager.  Both patches 
are totally untested.

After adding a small fix to the patch, this is now fixed in revision 455. 
Thanks jklandis.
