SyncLogger additions
- containerForceClosed(uuid, reason)
- modCompatSkip / modCompatSaved / modCompatRestored (per-mod tracing)
- storageSave(storageUuid, kind, detail) for backpack/SS/RS2 lines
- poolStats(exec active/queue/idle, hikari active/idle)
- warnPlayer / nbtAnomaly generic helpers
PoolStatsReporter.java
- Dedicated single-thread daemon scheduler, 5-min cadence.
- Reads VanillaSync.executorService stats via reflection.
- Reads HikariCP MBean via new JDBCsetUp.getPoolMXBean().
- Emits WARN logs when executor queue > 400/512 or Hikari active >= 14/15
so admins see saturation trends before they become outages.
JDBCsetUp.getPoolMXBean()
- Public accessor for the HikariCP pool MBean. Returns null when pool
is uninitialised / closed.
Wire-in: PlayerSync.onServerStarting starts the reporter, onServerShutdown
stops it before pool close.
Instrumentation
- VanillaSync.onPlayerLogout logs containerForceClosed for self + viewer
containers.
- ModCompatSync.snapshotAccessories logs modCompatSkip when cap==null.

PlayerSync
PlayerSync is a Minecraft Forge mod that synchronizes player data across multiple servers using a MySQL backend. It allows players to maintain their inventory, equipment, experience, advancements, and more when moving between servers in a network.
Mod Support
Any other mods support is also possible.
Development Setup
Database Setup (Docker)
A docker-compose.yml file is provided for easily setting up a MariaDB database instance for development testing.
- Make sure Docker is installed.
- Inside your work directory run:
This will download the MariaDB image (if not already present) and start a database container in the background.docker compose up -d - Stoppinng the Database
docker compose down
Data Persistence: The database uses a Docker volume, ensuring your data persists even if you stop and restart the containers.
Database Management Tool
The docker-compose.yml also includes an Adminer service, a lightweight database management tool.
- Access Adminer in your web browser at http://localhost:8080.
- Log in using the server with
- username:
playersync - database:
playersync - password: see docker-compose.yml
- username:
For debugging purposes, you can enable use_legacy_serialization to have readable database fields. This can cause crashes and unintended side-effects. Do not enable this on a production server if not absolutely necessary!
Running the Mod
The project uses Gradle for building and running. Use the provided Gradle wrapper (gradlew for Linux/macOS, gradlew.bat for Windows).
- Make sure that the MySQL database you configured is running.
- Run the Server
or on Windows:./gradlew runServer
This task compiles the mod and starts a dedicated Minecraft server instance with the mod loaded in the.\gradlew.bat runServerrundirectory. - Run the Client
or on Windows:./gradlew runClient.\gradlew.bat runClient
