XGamemode

Added

• Batch processing for offline player data with configurable BATCH_SIZE (default: 100) to prevent memory overflow when handling large datasets
• Centralized constant declarations (SAVE_DELAY, MAX_MAPPINGS, BATCH_SIZE, LOCK_TIMEOUT, SHUTDOWN_TIMEOUT) for better maintainability

Fixed

• Potential performance issue where offline player data was processed without pagination, causing high memory usage
• Redundant BatchResult inner class replaced with local variables for cleaner code structure

Changed

• Optimized processOfflinePlayersData method to process keys in batches instead of all at once
• Simplified handleBatchPlayers method by removing unnecessary BatchResult wrapper class
• Streamlined code formatting: compressed multi-line conditionals into single lines where appropriate
• Improved code readability with consistent constant usage across all methods

Removed

• Redundant BatchResult inner class (functionality replaced with local variables)
• Hardcoded thread pool size value (now using THREAD_POOL_SIZE constant)

Added

• Added debug logging for lock timeouts and interruptions
• Added pendingSaves set to prevent multiple concurrent save operations

Changed

• Improved Folia scheduler fallback logic: sync tasks now use Bukkit scheduler instead of direct run() to prevent main thread blocking
• Enhanced version detection to properly handle 1.8.8 format

Fixed

• Fixed potential main thread blocking when Folia scheduling fails
• Fixed lock timeout handling with proper debug logging for easier troubleshooting
• Fixed duplicate data saving by implementing pending saves tracking with ConcurrentHashMap.newKeySet()
• Fixed version parsing for formats like 1.8.8

Added

• Added comprehensive thread-safe locking mechanism using ReentrantLock for player data
• Added support for Folia server software with unified scheduling API
• Added debug mode with detailed logging for troubleshooting
• Added maximum mappings limit (10,000) to prevent memory leaks
• Added delayed save system (20 ticks) to batch disk writes
• Added batch processing commands: /gamemode -all, -online, -offline
• Added server version detection for spectator mode compatibility
• Added configuration auto-merge to keep config.yml up-to-date
• Added proper error handling with stack traces in debug mode
• Added player quit event handling to clean up locks

Changed

• Complete architecture rewrite with modular design
• Migrated from coarse synchronized blocks to fine-grained ReentrantLock
• Improved thread management: replaced scattered async calls with centralized 4-thread pool
• Enhanced name-to-UUID mapping with bidirectional cache (uuidToName + nameToUUIDs)
• Optimized data saving: from immediate writes to delayed batch saving
• Unified task scheduling for Bukkit and Folia platforms
• Improved command tab completion with offline player suggestions
• Refactored permission system with granular control (xgamemode.admin, xgamemode.others.*)
• Enhanced logging with color-coded console messages
• Restructured message system with better fallback support

Fixed

• Fixed thread safety issues in name-to-UUID mappings
• Fixed memory leak where player data never got cleaned up
• Fixed data loss risk from frequent uncoordinated saves
• Fixed incorrect console sender usage in logo display
• Fixed spectator mode detection on older server versions
• Fixed race conditions in player join event handling
• Fixed improper synchronization in data file access
• Fixed tab completion showing duplicate entries
• Fixed permission checks for offline player modifications

Removed

• Removed excessive synchronized blocks causing performance bottlenecks
• Removed redundant saveData() calls after every player join
• Removed unsafe HashSet usage in concurrent mappings
• Removed mixed tab/space indentation (now using consistent spaces)
• Removed deprecated scheduler implementations

I won't be sad when the final JAR file is big anymore! Stable > Everything! Screw you, JAR size!

• Optimized the plugin.

[x] Fixed the bug that cause error when closing the server.
