World Bugs and Crashes List

[John Adams]

Devs, let's work from this list for a while.


The Linux World seems to be crashing a lot more lately than before, though it also has had a lot of visitors in the last 24h. I will post backtraces I find this weekend here to keep things focused.

My first complaint is that just shutting down the world (with a killall) seems to have new results I haven't seen before:
[quote]Killing old current_world loop...
pure virtual method called
terminate called without an active exception[/quote]

New Telon will be in DEBUG the next few days to try and catch these crashes. I urge people to continually TRY to crash it, because that's what Alpha is all about.


Applying Foof's FragPacket fix today.

This was me, on a 2nd acct, connecting to char select but my toon wasn't found or something (Tweaker). Even though he exists.

Should all be fixed..just null pointers

[Sacred]

Did I break something with screwing with chat? Also, been playing with the server more and more, so if I need to knock anything off, send me a PM. All my toons during test will contain "Sacred" in their name for easy ID.

[John Adams]

No it's fine, we need crashes to root out these issues. Crash away.

Foof, this one still crashing:

Also, the 1 error per spawn that is assigned this script, is this wrong? My script?

function hailed(npc, spawn)
    if npc ~= nil then
        Say(npc, "Gnomes rule, elves drool!")
    end
end

If the script is fine, I'd like to find out where that's happening and stop it. Finding it hard to trace bogies when my screen disappears.
