This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.

Subject: [PATCH] Prevent Saving Bad entities to chunks
|
|
|
|
See https://github.com/PaperMC/Paper/issues/1223
|
|
|
|
Minecraft is saving invalid entities to the chunk files.
|
|
|
|
Avoid saving bad data, and also make improvements to handle
|
|
loading these chunks. Any invalid entity will be instant killed,
|
|
so lets avoid adding it to the world...
|
|
|
|
This lets us be safer about the dupe UUID resolver too, as now
|
|
we can ignore instant killed entities and avoid risk of duplicating
|
|
an invalid entity.
|
|
|
|
This should reduce log occurrences of dupe uuid messages.
