New SyncLogger utility class: - Writes to logs/playersync/sync.log (separate from MC console) - Automatic rotation: 10MB max per file, 5 files kept - Thread-safe: lock-free ConcurrentLinkedQueue + async flush - Categorized log levels: INFO, WARN, ERROR, DUPE_RISK, DATA_LOSS, RACE, PERF_SLOW, SAVE, SAVE_FAIL, SAVE_SKIP, RESTORE, EVENT, GUARD Tracked events: - Every player join/leave with sync status - Every save (logout, shutdown, death, auto-save) with duration - Save failures with error details - Saves skipped (uncompleted sync, dead player) - Cross-server race conditions (poll loop waiting) - Player disconnects before sync apply (potential data loss) - Duplicate login kicks - Slow operations (> 50ms threshold) Usage: check logs/playersync/sync.log on your server for diagnostics. Look for DUPE_RISK, DATA_LOSS, RACE, SAVE_FAIL entries. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

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
