Crash pmmp4

Hello everyone I have an unexpected error, who can help? Link - https://crash.pmmp.io/view/5991579

 

sus

 

?

 

Do you think that if I disable this plugin, there will be no error?

 

No, I was just commenting on the name of the plugin.

Your error was caused by you doing something with a player who wasn't online

 

Well, how can I find out which plugin does exactly that?

 

No idea. There's nothing in your backtrace to know what "plugin" caused it. This seems like it's an issue with your server itself

 

Or simply try uninstalling plugins one by one

 

So you think the problem isn't with the plugin?

 

Well that's my guess.

 

Hey! I have the exact same error with PMMP 4.2.1
Crashdump: https://crash.pmmp.io/view/6033735

 

I bet PurePerms causes the crash and it only happens after a player with "*" permission has been disconnected (by transfer) and a message is broadcasted. Right?

 

Yes! EXACTLY, why is it doing this ?

 

I think it happens in PlayerQuitEvent when PurePerms::unregisterPlayer() removes the PermissionAttachment. It causes that the player is added again to the broadcast channel subscribers, maybe because $player->removeAttachment() triggers permission recalculation.

A possible workaround would be to add the following line to the end of the function PurePerms::unregisterPlayer():

PHP:

$this->getServer()->unsubscribeFromAllBroadcastChannels($player);

 

This patch seems to work, will tell you if the error is triggerred again! Tysm, appreciate the help.
I will maybe open a change request on the github page of Pureperms in order to patch the bug
