rev744 issue

[Blackstorm]

Hello,

I posted that on the IRC but i think no one check it or see it because i didn't have any return... so i reporting it here.

Since the rev744 (svn 746), when i want to chunk in the Cragwind Ridge zone, my server crash each time.

i have completely recompiled the binary with the official sources, deleted all the svn repo and redownloaded it, install the official DB (i just reimported the characters infos) and nothing change...

If someone have a Worldserver on a linux server can you confirm that please ? actually the server break without sigfault or error messages...

[John Adams]

I found an issue in Linux (only) with the logger Lokked uses to report more than a 100% spawn total for placements (linux doesn't like single % signs in a string). Not sure if this is your issue, but how I discovered the problem was to run the vgemu-world in debug. Do so like this:

Code: Select all

gdb vgemu-world

When the sigfault happens, type:

Code: Select all

bt

and hit enter, then copy/paste that whole stack here to we can see exactly what breaks.

[Blackstorm]

Hum... first time i am using gdb...

i need to start the server before, running the gdb command ? or gdb vgemu-world should run the worldserver process ?

otherwise actually, if the server already run and i use the gdb command, the bt return say : "No stack" after the crash.

[John Adams]

Yes, sorry. Thought you were a Linux debugger Yes, you have to "run" after gdb vgemu-world (just the 'r' key).

If you have "no stack", then there is nothing I can do to help. Ensure your code is not modified from Public SVN, and that the data you use is vgo_world.sql. If there are still crashes, then do an OS update (aptitude update / safe-upgrade) maybe. I cannot think of anything else.

As John mentioned, try removing the % sign that I've put into the Log* statement in InitChunkNPCs of MasterSpawnList class and let me know if that works.

How does one include a % in a string that's gcc friendly??

[John Adams]

Code: Select all

100%%

My committed fix was removing % and replacing with the word "percent". It's just a logger.

[Blackstorm]

yop ^^

Thanks guys ^^ like you said, the only "%" is the cause ^^ if you delete it, it's working fine and if you protect it "%%" it's also works ^^
