mtmaps (OpenMP)

kero99 · November 23, 2009

If you are using mtmaps, need:
MapUpdate.Threads = 2 in mangosd.conf, 4+ very unstable

disable save,saveall commands and server save time interval 10-20 min.

And patch for database, prevent crashes on SqlDelayThread and removed ACE_Based::Thread::Sleep(10), thx Derex and Ambal.

http://paste2.org/p/528578 - updated, fixed typo in include, sorry

This patch make problems with last Mangos and SD2 revision, mangos-world freeze at start load SD2 C++ Scripts

I test with 8859 and 8866 and same result, with this patch core freeze at SD2 loadind, but without that.. all ok

I use since a while a similiar SQL configuration as nanounico does and I cant complain with the performance, you only need enough RAM.

The only part which I don't really get is...

query_cache_size = 356M
query_cache_limit = 64M

Are you sure that it is a good idea?

You need have ACE precompiled and installed in your system =), this tag is needed if you want to work with ACE 5.7.x

After installation of a patch the server got сrash.

Also got сrashes in different places at various times without any sequences.

For example:

mtmaps ACE (8799+):
http://paste2.org/p/508050

I hope you could help me..

On windows 2003 x64:

I have applied this patch to 9025 succesfully

mtmaps ACE (8799+):

http://paste2.org/p/508050

I have downloaded and compiled ACE 5.7.2 and now i have

ACE.dll

ACE_gperf_lib.dll

But i don't know what to do next....

I have tryed just to mix broth overwriting the ACE.dll compiled with mangos but doesn't works...

Thank you for your patient :unsure:

xarly · December 20, 2009

Just a little clue please...

przemratajczak · December 20, 2009

afaik ACE-based mtmaps does not support windows environment.

przemratajczak · January 2, 2010

MaNGOS 9035 (instider/old) + OpenMP mtmaps

UDB 385

SD2 1513

Debian 5

http://www.pastebin.org/70560

http://www.pastebin.org/70561

http://www.pastebin.org/70562

and many more with occurence 1-4h during day when population around ~700, but becoming rare after ~21:00 when pop drops below 400. I think that those are caused by mtmaps but I'm not sure. Previously i suffered of constantly crashing MySQL. Reinstaled and reconf MySQL application that it is working stable now.

anyone seen somethong like that?

thenecromancer · January 2, 2010

You should prevent some unsafe stuff. For example Unit:ProcDamageAndSpell() should better do nothing if this->isInMap(pVictim) is not true (eg. both units are not in same map). (looking at those not-quite-useful debugs this might be your case)

Instead of that you could do the following which is better IMO

Crash with the sql patch... (http://paste2.org/p/528578)

Can you help us?

EDIT: when it crash, 1 player dissapear from the database ?! Possible? The problem is maybe located in player::savetodb... The DELETE clause can be deleted and the INSERT clause change to REPLACE... But I'm not sure this bug is caused by this patch...

crashuncle · January 26, 2010

Any updates about this patch? I saw quite a few changes in the 0.12 GIT which seemed to affect multithreading. Someone knows what is the best Mangos revision for openMP or the best MT patch for the latest revision?
