Hi,
On my APE server, I generate moves from an Artificial Intelligence. When my
server has worked for one month, it sometimes loses track and my robots
never play. Here is my simplified code:
function wait_for_new_move()
{
var move_number = ask_for_robot_move()
play_move_number(move_number);
}
function ask_for_robot_move();
{
... Artificial Intelligence...
return move_number;
}
Now, here is what happens when things go wrong: wait_for_new_move() is
called as usual and then ask_for_robot_move() too. But then this function
stops after some computations at some point and never returns and
wait_for_new_move() also never executes what is behind ask_for_robot_move()
call.
My logs shows that APE keeps working and deals with queued events straight
after that.
I strongly suspect memory leaks to be the cause of that behaviour, but
there is probably not much I can do until I patch APE (with Cliff's update,
see https://groups.google.com/forum/?fromgroups=#!topic/ape-project/UJqh4rCvukc
thread) and I need Mysql to work with this new version of APE to do that...
For the moment, I am trying to detect when this bug occurs and find a
workaround. The workaround is easy. If the robot has not played within 3
seconds, I can either rerun wait_for_new_move() or simply cancel the game.
My questions:
1) does that kind of silent crash ring a bell to anyone?
2) do you know of a way to simulate such a silent crash without writing
code (a series of return NOTHING). A division by zero does nothing.
Javascript code keeps being executed. Is there something stronger to really
crash the function for good?
Thanks for you help.
Nicolas.
