xp_bugfix - nwn2server bugfixes

[Rossman]

I'm using the NWN2 DB for some things (i try to use the mysql db instead, but for some things i'm sill using the nwn2 db), even on the onload scripts (i have a lot lot of things to do in the module load so i create a way to split these tasks in 3 different scripts).
Sometime the memory allocation drop down to 400-500 mbytes, but it's quite random and does on depends of the plugin.

Hi Skywing,
two simple questions on xp_bugfix: what stand for, and is there a way to disable logging of these notifications at server shutdown?

[Skywing]

They're debugging messages; the game is probably trying to individually remove some objects after it flushed everything out in the game object table as a part of shutdown processing. Note that shutdown in NWN2 has some bugs in general so I'm not terribly surprised by this.

I can see about turning these messages off by default for the next release.

[Skywing]

Released xp_bugfix 1.0.15.

This release partially enables the SetAreaTransitionBMP script function, which has never worked. (Now, the nPredefinedAreaTransition parameter will be honored. The sCustomAreaTransitionBMP parameter will still not function, however, because the game client doesn't have the corresponding client-side code necessary for it to work.)

Additionally, this release includes a packet filtering API that is necessary for the server vault plugin to function.

[Skywing]

Released xp_bugfix 1.0.17.

This fixes a problem with the xp_bugfix API for adjusting the game world update timer, which didn't work properly. (The config file directive did, however, work.)

The update is only meaningful if you were using the API.

Could you disable those debug messages in your next release?
The file xp_bugfix.txt gets bigger and bigger everytime i close/shutdown the server. Also, the server crashes when i shut it down due to the huge amount of log entrys.

And, why is it doing this anyway? what's wrong with all these objects?

[Skywing]

The server crashes because of known bugs in the server and not due to the log messages. Shutdown has been unreliable from the beginning.

I'll investigate adding an option to suppress the messages with respect to cluttering the log.

Himmelweiss, I think he's saying the crashing has always been that way with nwn2 server.
xp_bugfix is just showing you errors related to it. It's not causing the crash though.

[Skywing]

When shutting down, the server corrupts part of its memory and that can cause crashes during the shutdown sequence sometimes. That isn't due to xp_bugfix as far as I know, and sometimes you may simply 'get lucky' and not see any crash at all because nothing important was corrupted.

Any NWNX plugin that does memory allocations may shift things around so that something else might have gotten damaged by the heap corruption issue.

Since this is only a crash at shutdown time issue and seems to happen after all players have been saved, I haven't invested any time in patching the server to not do that anymore (after all the server process is about to go away anyway).

[Himmelweiss]

Ok that makes alot more sense to me, thanks for giving more details.

I just use NWN2 since about 2~ month, so i'm not really familiar yet with all it's bugs/crashes.

Is there an open source of your plugins? Then i could just disable the debug messages on my own. If not, np at all.

[Skywing]

The source code is checked in to virusman's SVN repository. (skywings_dev_branch). I believe one of the stickies lists the connection information for the repository.

Contributions are welcome, although I would prefer to roll any improvements up into the standard distribution so as to avoid causing problems when users want to upgrade to a new version.

[Himmelweiss]

Thanks, i have found it.

Noticed that you are making use of wxwidgets, have to read into that first before i can adjust your plugins to my needs (i have never used wxwidgets before).

I had to convert the project so i can use it in visual studio 2010. But so far it looks like the convert doesn't cause any issues.

[Skywing]

wxWidgets are a part of the base distribution.

I would rather that the plugin did not depend on them. The newer NWNX plugins that I have written do not use the base distribution's build system for this reason. xp_bugfix is old and still uses the 'official' build environment.
