Never rewrites existing config files (server.properties, bukkit.yml, commands.yml, spigot.yml, pufferfish.yml, purpur.yml, and the Paper configs). Missing files are still created with defaults. Commands that vanilla would save to server.properties (/whitelist on|off, /setidletimeout) only last until restart.
Hides "lost connection" messages in the console.
Keeps chunks loaded while a zombie villager is being cured.

EXPERIMENTAL (may break things):

Stores player data in RocksDB (world/playerdatadb) instead of .dat files. A plugin-facing PlayerDataApi (reached via PlayerDataStorage#api()) exposes get/saveAll/has/seen/drop/copy/flush; corrupt stored data refuses the login instead of handing out a fresh profile, and dropping a world with no stored data is treated as success. The replaced revision of the default profile is kept under a previous column family as a manual recovery net. Plugins reach all of this through Utilities-OG, never the fork API directly.

Building

Clone this repository (do not download it), then:

./gradlew applyPatches             # sets up Purpur-API and Purpur-Server
./gradlew createReobfPaperclipJar  # builds the runnable server jar into build/libs

Patches are commits in Purpur-API / Purpur-Server; after editing their source, ./gradlew rebuildPatches regenerates the patch files under patches/. See CONTRIBUTING.md for details.
