1. CRITICAL - Anti-dupe: Player inventory mutations now run on the main server thread via server.execute(). DB reads stay async, but all setItem/setHealth/addEffect calls happen on the tick thread. CountDownLatch ensures the lock is held until apply completes. 2. CRITICAL - Resource leaks: 3 QueryResults in PlayerSync.java startup now use try-with-resources + PreparedStatements instead of raw String.format SQL. 3. HIGH - Curios save: UPDATE changed to REPLACE INTO to prevent silent no-ops when the curios row doesn't exist yet (new player who died before first init save). 4. HIGH - RS2 restore: Removed skip-if-exists check. DB is always the source of truth - stale local data was persisting permanently. 5. HIGH - Race conditions: Shutdown save now acquires per-player lock. All logout saves (curios, mod-compat, inventory) moved inside doPlayerLogout under a single lock acquisition. 6. HIGH - SQL injection: DATABASE_NAME validated against [A-Za-z0-9_]+ regex on startup to prevent injection via config. Vyrriox |

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
