Subject: [PATCH] Use offline uuids if we need to
|
|
|
|
By default, the user cache falls back to requests to mojang if it wasn't able to find a player.
|
|
This is completely fine if we're running an online mode server, however proxies require the
|
|
server to run in offline mode, which makes mojang's default commands to not work properly
|
|
( say if we want to ban a player which has never joined the server, he wouldn't get banned )
|
|
|
|
What our change does is make use of already existing options in paper.yml and spigot.yml to check
|
|
if the server is running behind a proxy and if the proxy is running online mode. If admins fail to
|
|
configure it properly, their mistake!
|
|
|
|
Furthermore, my research on the issue shows that this behavior also can be seen if we're not running
|
|
behind a proxy at all! I try to whitelist any of my staff, and they get whitelisted with online mode
|
|
UUIDs, while they should get whitelisted with offline mode ones.
|
|
|
|
Thanks to Gabriele C <sgdc3.mail@gmail.com> for pointing this issue to us, as he said paper doesn't
|
|
have any interest fixing this.
