AOS Tooltip crash [all core versions]

Developer Silver · **Posted:** Wed May 24, 2006 5:28 pm

With every core version I've tested, our tooltip hook crashes POL... I can't figure exactly where is the problem, but I've saved some crash dumps (generated with 2005-05-09b core) to attach here...

If someone remember, I've posted this problem on yahoo group on past December... and it still torment our dreams!

We love tooltips, but we can't use them on our shard!

Someone can help us?

P.S.: anyone here has a full working tooltip hook?

What is it you are using your tooltip hook for? Tooltips are functional now (including notoriety) in the core.

Tested with latest core... no good result... same crash as usual.
Here's a fresh new dump.

Sure

It's the same uopacket.cfg posted on yahoo groups:

Code:

Packet 0xD6
{
   Length      variable
   SendFunction   pacchetto_tooltip:tooltip_hook
}

as u posted somewhere, it will not crash everytime... so, it would help a lot if u could syslog the packet u'll send via hook so we can take a look... my own tests with your code doesn't crash.

I had the same problems you fellas had. If you SetUnicodeString nullterminator to 0 it'll crash the server.

Anyway, I've been working on it for a week and finally got it all working.

It's just a basic starter.

(yes I posted this in two topics, just want to make sure you guys get it and figure out the problem.)

Ok we're merging our script with the one posted by Unreal, and in the first tests it seems to work well.. we'll up the result to the live shard to do a better stress-test and we'll report here...

Modifications made are about managing of SetUnicodeString(), setting strings size and minor adjustment of packet indexes.

If it will work, the problem were 90% in SetUnicodeString()

The strange thing is: how's possibile that a malformed packet show perfectly on client, but crashes POL? :?:

@Shini: what syslog do you need? A print of packet before and after our hook? (the old, crashing script)

I should remember which Postings are interessting... that's why I HATE webforums... and would use NewsServer (nntp) if available - because u can decide what u've read...

anyway... the packet looks fine, yes... but something in internal packet-build structure will destruct stuff... ok, it's fixed in past 20060916 releases (pol096.4 & pol097)
