Server crash with Player.get_view_coordinates() and @EntityPreHook #233

Closed ThaPwned closed 5 years ago

ThaPwned commented 6 years ago

Info:

Date          : 2017-12-17 20:33:10.774142
OS            : Linux-4.9.13eorfix-x86_64-with-debian-8.9
Game          : csgo
SP version    : 622
Server plugins:
   00: Source.Python, (C) 2012-2016, Source.Python Team.
SP plugins:
   00: crash_test

Code to reproduce the crash:

from entities.hooks import EntityCondition
from entities.hooks import EntityPreHook
from memory import make_object
from players import UserCmd
from players.constants import PlayerButtons
from players.entity import Player

@EntityPreHook(EntityCondition.is_player, 'run_command')
def run_command(stack):
    player = make_object(Player, stack[0])

    if not player.dead and player.steamid != 'BOT':
        usercmd = make_object(UserCmd, stack[1])

        if usercmd.buttons & PlayerButtons.FORWARD and not player.buttons & PlayerButtons.FORWARD:
            player.get_view_coordinates()

Thanks! I'm able to reproduce the crash with CS:GO. Here is a crash dump:

----------------------------------------------

The funny thing is that it seems like it's crashing while a hook is being created. I will investigate this.

KhaimovMR commented 5 years ago

I think I've got related problem on linux.

from players.entity import Player
from events.hooks import PreEvent

@PreEvent('weapon_fire')
def on_weapon_fire(event):
    player = Player.from_userid(event['userid'])

    if player.view_player:
        player.view_coordinates = player.view_player.eye_location

The problem only comes out when this code executes on PreEvent. Everything works fine If we change PreEvent to Event. If not - dedicaded linux server is crashing.

The crash is occurred on the line:

    if player.view_player:
