 |
|
Hello everyone,
I am looking for NWNX plugin that provide function to regular end of NWServer. Something like DMREBOOT from NWN-FF.
Solutions I tried (and don't like):
 NWServer can be shut down from command line. Process can be closed, killed or even crashed. Command is sent via LETO.
Certain NWScript constructions may cause imidiate crash.
Plugin I found here cause NWServer crash. This is pretty much same as previous solution.
Use NWN-FF.
I know how to make restarts safe. Refuse new logins, boot all players etc.. I just dislike time out message players recieve. I think NWN-FF solution is way better.
Is there such plugin? |

I never seen C++ before but I guess it can't be so hard. I mean, NWN-FF is open source, it should be possible implement similiar function to NWNX.
Or maybe not. Excuse me  |

| Isn't there some command called KILLSERVER that you can send to NWNX from NWN? |

Please tell me whether this fixes the issue or not. |
Is this modified plugin from Asmodae?
| Code: | | SetLocalString(GetModule(), "NWNX!RESETPLUGIN!SHUTDOWN", "1") |
For me it doesn't work. It only crash crash server much faster then before. Characters are not saved and player time out. |

Ahhh. OK.
Save and boot players in a delayed loop. In the meantime you block anyone entering with BootPlayer in OnClientEnter. |

The way I handled this for NWNX4 was to find the server GUI window and post a WM_CLOSE message to it. This cleanly logs players out, saves characters, and shuts down.
I believe that this will (probably) work for nwserver.exe as well as nwn2server.exe in principle. For the linux nwserver, I assume that you'll have to do something a bit more complicated. |

I just made it. I'll post final dll when I put it all together.
I found alot useful guides on MSDN.
How my rebooter work:
NWNX recieve reboot command.
Plugin enumerate running processes and find PID of nwserver.exe.
ID is sent to function that attempt terminate process by WM_CLOSE.
Function return SUCCESS/FAILURE.
NWServer is regulary closed, characters saved and NWNX restart it.
// I can add KillProcess if regular close failed, not sure yet. Or sent failure message to module. |

You could also look at the following functions in the NWNX4 controller:
NWNXController::findServerGuiWindowEnumProc
NWNXController::findServerGuiWindow
NWNXController::performGracefulShutdown
It seems likely to me that the window class is probably the same for nwserver as for nwn2server.

I created small plugin with functions I needed for my server.
It is my first try in C++ so i guess code is not very good, but it do what I wanted.
Implemented funcions:
| Code: | | SetLocalString(GetModule(), "NWNX!SHELL!SHUTDOWN", "CLOSE"); |
This cause regular end of NWServer, characters are saved and application closed.
| Code: | | SetLocalString(GetModule(), "NWNX!SHELL!SHUTDOWN", "KILL"); |
NWServer process is terminated imidiately. This not giving NWServer chance process ending sequence and players recieve timeout message. This is well known "crash" function.
| Code: | | SetLocalString(GetModule(), "NWNX!SHELL!CMD", "command string"); |
This pass command string to operating system. Usually cmd.exe but can be anything defined in %COMSPEC% variable.
Known Issues:
My plugin not working with more then one instances of nwserver.exe. Copy with lower process ID (PID) will be affected.
If somebody find my plugin useful, here is download:
http://www.aurilites.com/NWNX/nwnx_shell.zip
I will be adding more functions later, everything related to operating system. If you find bug or have idea how improve my plugin, let me know

You should filter the window you search for by the current process ID to solve the problem of not working with multiple instances.
(see GetWindowThreadProcessId, GetCurrentProcessId) |
