Hi.
I beleave this question might be for the more experienced coders and
gurus on this list, so don't bother to read the message if you're very
new to this implementor thing (unless you're allso having 'trouble' with
'ticks not updated'). So much for the warning *grin*
Anyway, I'm slightly satisfied that it seems, as if I got the most 'crash
bugs' out of the mud I code on, unfortunately I'n receiving those damn
"TICKS NOT UPDATED" automatic shutdown things now. It's my understanding
that all causes to such a 'bug' should not exist in the straight
circlemud code (the mud is based on bpl8). The mud has been pretty
heavily modified though, and thus the most probable cause for this 'tick
error' would be some part of the code that I've added.
In the proccess of debugging the mud I used some of the GDB scrips that
were strewn arround here lately, and made a few modifications to the
interpreter.c, so that I get the LAST executed command, the room in which
is was executed, the arguments, and the players name. All this functions
nicely, but ermm.. It's helped me to debug the few real 'crashbugs' which
were difficult to find in anything but constant play, but now I'm faced
with the reality, that I can't figure out whats wrong.. *sulk*
All I get is ticks not updated errors on the commands quit and kill.
I might've found the cause of the kill stuff, as there was a level 0 mob
on the mud, it's fixed now, but it's yet to be seen if it works :)
On the quit command however, I'm totaly left out in the bare. It's not
happening the first time someone quits, just 'sometime' when the mud
feels like it..
This is what I get from GDB (combined output from gdb and the syslog).
[ GDB START ]
Sun Jul 7 10:47:30 :: Brightstar has quit the game.
Sun Jul 7 10:47:31 :: Losing player: Brightstar.
Sun Jul 7 10:51:49 :: SYSERR: CHECKPOINT shutdown: tics not updated

(gdb) $2 = "quit", '\000' <repeats 252 times>
(gdb) $3 = '\000' <repeats 256 times>
[ GDB END ]
$1 is the name of the player, $2 is the command (QUIT! :P) and $3 the
argument(s) if any.
In this case the mud had an uptime of a few hours.
Any help and/or sugestions how to track down such 'tick bugs' is
appreciated.
Regards,
Con.
