Subject: [PATCH] Stop wasting resources on JsonList#get
|
|
|
|
Previously, when a banned player attempted to join the server was removing all the stale entries.
|
|
This caused a resource waste, which was unnoticeable to users that use ban plugins which doesn't
|
|
use the ban list. Akarin's changes for saving it async lowered the pressure, however it was
|
|
still pretty high.
|
|
|
|
Our changes are the following:
|
|
1. Stop removing all stale entries when JsonList#get is called.
|
|
2. Only if a player joins and his ban has expired, remove his ban which triggers a save which then
|
|
triggers removing of all stale entries.
