[ANY] Command and ConVar - Buffer Overflow Fixer (2.9) [23-Jan-2024]
 
31 Attachment(s)
About:
  • This plugin fixes servers with too many ConVars, which causes a buffer overflow error in server console and the overflowed ConVars to use their default value instead of the one specified.
  • This should also fix commands which failed to be executed caused by the same buffer overflow.
  • Note: If your server is hibernating the fix will happen on the next frame when it wakes.
  • Initial thread and plugin version here.
  • This fixes "Cbuf_AddText: buffer overflow" error messages.



Related Plugins:


Supported Games:
  • CS:S
  • CSGO
  • L4D1
  • L4D2

Not required from my testing. But added.

2.1 (07-Aug-2018)
- Added support for GoldenEye and other games using the OrangeBox engine on Windows and Linux.
- Added support for Left4Dead2 Windows - not required from my testing on a Dedicated Server.
- Gamedata .txt and plugin updated.
All OrangeBox games seem to suffer from this bug, plugin should now support them all.

Edit: Theres a new version of DHooks which no longer crashes the server when reloading a plugin using the "functions" gamedata section. I suggest everyone update to this goodness.

Enjoy

Something that was needed for so long. Amazing work as always.

Line: 108
PHP Code:
if( cvar != INVALID_HANDLE && GetConVarInt(cvar) != 1 ) cv++; 
:arrow:
PHP Code:
if( cvar != INVALID_HANDLE && cvar.IntValue != 1 ) cv++; 
Just sticking to object oriented API.

Errors:

command_buffer.smx ([ANY] Command and ConVar - Buffer Overflow Fixer): Native "DHookCreateFromConf" was not found

Other plugins that require Dhooks work. I do have command_buffer.games.txt in my sourcemod/gamedata folder.
