Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Fix commands from signs not firing command events
|
|
|
|
This patch changes sign command logic so that `run_command` click events:
|
|
- are logged to the console
|
|
- fire PlayerCommandPreprocessEvent
|
|
- work with double-slash commands like `//wand`
|
|
- sends failure messages to the player who clicked the sign
|
