Did you extract maps and vmaps?

Do you have them enabled in mangosd.conf?

Look for Rates.XP.Kill in mangosd.conf

I believe I have mmaps_zero working, and I have updated that branch on github

For mmaps_one, I don't want to spend time on another db/client/patch/etc

Instead I'll give you two different patches to test. Tell me which one works.

Patch ONE

Patch TWO

sorry for double post...

I don't think adding vmap checks will solve the falling-underground problem, because vmaps don't perform tests on terrain terrain. I can see the corner cases where the random destination is on the other side of a wall, so our path takes us through 10 rooms. This is a problem with the naive random destination selection - it only cares about euclidean distance, not walking distance.

There are some detour-provided things we can leverage to solve this problem. dtNavMeshQuery::findLocalNeighbourhood will give us reachable polygons within a certain range, which can confine our 'random' destination to an area that is reasonably within the walking distance we specify.

I am going to start writing something to explain this project, more detailed than 'look at the code'- what has changed, what is new, how it works, etc. This will hopefully help any reviewer(s).

Also is mentionned in the Wiki to copy to the server files : dll. exe. and pdp… only found dll. files.

I fixed a extractor bug for zero and one.

In order to work on these further, I need help finding a db for zero and one (everything seems out of date), please PM me if you can offer assistance.

Maybe something gone missing at porting.

The dep/recastnavigation/RecastDemo/Bin/ dir was missing, but I fixed it just now. Now there is no difference between mmaps_clean and mmaps_rewrite

It isn't related to the flying problem of course

@leak

I know there are some platform limitations on the number of concurrent aio operations a process (or even system) can have. I have tried my best to combat this, but in some cases it will be better to use a reactor for performance reasons (I have logging which should alert people when this is the case).

As for the windows problem you specifically pointed at, I may be able to help:

The FD_SET macro silently fails if fd_set::fd_count >= FD_SETSIZE

Also, deep in ACE, there are no bounds checks when adding sockets to the fd_set

The select reactor will lose all data sent to sockets added after the platform-specific size limit was reached, because the socket is never included in select calls.

One solution for the Trinity codebase (mangos has some different classes, but we would need the same thing to address this problem).

Count the number of current active connections in RealmAcceptor

In RealmSocket::open, if this count is greater than the platform limit,put the RealmSocket in a queue - do NOT call Base::open or RealmSession::OnAccept

When a socket closes, it should unregister itself, then dequeue a RealmSocket and call its Base::open and RealmSession::OnAccept

The platform limit should be ACE_DEFAULT_SELECT_REACTOR_SIZE

(this is all very similar to the algorithm I came up with for the aiocb list limitations)

@anybody that cares

I've made further improvements to my aio branch - please check them out and let me know what you think.

I tested 750 clients again, this time with CMSG_PING every 30 seconds. Latency seemed high, but I'm unsure if it is due to the proactor or if it's because those 750 clients are all in one .NET thread. More testing needed...

It crashes because you apparently have an empty string for DataDir in mangosd.conf

You would have to modify the core

Specifically, implement a chat command similar to WorldSession::HandleBattlemasterJoinArena, and probably chat commands to handle arena team create/delete/etc.

It's not a trivial mod though, and would require some programming skill

In addition to the above, you can get more information on auras and their effects by

• looking up the spell on a wow data site (like this: http://old.wowhead.com/spell=1715)
  
• using the .list auras on a creature
  
• finding/using a dbc spell viewer
  

Decided to try a little test:

750 clients, idle at character screen (my c# client, so not even CMSG_PING)

I think it shows the weakness of select-based servers, and that for large servers there is some performance gain to be found.

I'll work on having the clients send data (ping or some invalid opcode w/ data). This should give a more realistic comparison since we will get to test completion callback vs fdset scanning (and also will ignore the 'overhead' of the mangos core )

Download results here.

PS: found some crashes related to outstanding async operations which dereference already-deleted sockets, so I will have to work on that as well.

PPS: should have probably explained the images...

• For the CPU graphs, look at the graph and not the label.
  The label is the % at the moment I took the picture, which could have been during a context switch, etc.
  
• There is a CPU spike when the clients start connecting, and you can use the private bytes graph's slope to judge connection rate
  
• The select/debug graph is off a bit, clients were running slow due to attached debugger
  Thus, actual connection rate is probably higher
  
• If there are any questions, just ask!
  

The client does not support this.

mangos chat commands could be used as a workaround

vmapExtractor3 didn't find your wow client directory

put makevmaps_SIMPLE.bat, vmapExtractor3.exe and vmap_assembler.exe in your client directory, then try again

The behavior you describe isn't intentional - it sounds like something is wrong with your server.

Can you set your log level to 3 and post the parts where this starts happening?

Following is still in 'alpha', it won't compile:

mangos one => mmaps_one

mangos zero => mmaps_zero

both depend on not-backported parts from master

I can't test the validity of these parts for older clients

• ByteBuffer::appendPackXYZ
  
• SplineFlags::SPLINEFLAG_CATMULLROM
  

I just need to delete this copied version and download the 3.3.5a client?

Yes

updated to [11204]

Also created a new branch, mmaps_clean - it is a rebased version of mmaps_rewrite

With qsa's approval, I will post this branch in Under Review forum

Sorry, I never intended to push the charge movegen into the repo... not sure how that happened.

PS: if you want to use it and/or figure out a way to complete the implementation, I still have the code on gist: https://gist.github.com/791419

patch to use shortcut if tiles are not loaded or do not exist (untested)

https://gist.github.com/842876

Just recently added, I haven't looked at it very much:

https://github.com/Lynx3d/mangos/tree/transport

Hrm, branch deleted.

@salja

Can use use the mmap debug commands to test your server first?

• .mmap stats, .mmap loadedtiles
  Lists stats about the navmesh for your current map/instance
  
• .mmap path
  Tests the navmesh by generating a path to your current target (turn on gm mode to see the path)
  
• .mmap testarea [radius]
  Like .mmap path, but test multiple mobs around you (for load testing)
  
• .mmap loc
  Sort of like .gps
  

They may help you solve your problem, or will at least give us more information.

Wouldn't that be UNIT_FIELD_POWER_REGEN_FLAT_MODIFIER + 6?

With 6 being POWER_RUNIC_POWER...or maybe i'm just totally wrong too ^^

This makes much more sense, but nothing like that is in clean core.... custom patch?

Sure you're not forgetting about the Holy talent Infusion of Light?

I don't understand...

46 =/= PLAYER_QUEST_LOG_2_3 + 1

Are you saying 46 is the value of field PLAYER_QUEST_LOG_2_3 + 1?
