PerformanceAnalyzer

[2.3.4] - 2026-05-07

Fixed

• Redstone False Positives in Performance Drop Analyzer: Removed 26 non-performance-impacting blocks (buttons, pressure plates, lecterns, daylight detectors, tripwire, levers, targets) from isRedstoneComponent(). These blocks appear in naturally generated structures (villages, temples) and caused massive false positives through sampling extrapolation
• Redstone Sampling Extrapolation: Added minimum threshold (≥3 components found) before extrapolating redstone counts. Previously, a single naturally-generated button was multiplied by ×64, producing false "problematic redstone" reports
• Wrong Coordinates in Problematic Chunk Reports: Chunk coordinates are now displayed alongside block coordinates ([Chunk X,Z | Blocks ~X,Z]) for easier in-game navigation
• NullPointerException in PerformanceDropAnalyzer: worldInfo.get("name").equals(...) replaced with Objects.equals() to prevent NPE when world name is null
• Swallowed Exceptions in Chunk Analysis: ChunkSnapshot and synchronous chunk analysis errors are now logged at FINE level instead of being silently ignored
• Unbounded Database Queue (OOM Risk): DatabaseManager.logAsync() now enforces a maximum queue size of 10,000 entries. Prevents OutOfMemoryError when the database is unavailable for extended periods
• Excessive Block Checks in MovementChecker: isNearLiquid() reduced from 27 block checks (3×3×3 cube) to 7 checks (current block + 6 adjacent faces), reducing CPU load per PlayerMoveEvent by ~74%
• Duplicated Alert Cooldown Constants: AlertManager and MovementAlertManager now use the centralized Constants.ALERT_COOLDOWN_MS instead of defining their own identical values
• Silent Config Parsing Failures: Invalid alert categories in AlertPreferenceManager now log a warning instead of being silently skipped
• Thread-Safety in WorldStatsManager: Trend history lists now use Collections.synchronizedList() to prevent concurrent modification issues

Added

• Constants.DB_MAX_QUEUE_SIZE — centralized maximum queue size for database log entries
