AuctionHouse by ilius

v1.0.4 Changelog

Bug Fixes

• Fixed a race condition where expired auctions could be delivered to both the buyer and returned to the seller's mailbox under high load
• Fixed memory leak: GUI click cooldowns were never cleared, accumulating one entry per unique player forever
• Fixed memory leak: mailbox cache was retained for offline players indefinitely
• Fixed memory leak: transaction lock map could grow unbounded if cleanup was missed on exception paths
• Async-wrapped seller info GUI back button — no longer blocks the main thread on a database query

Compatibility

• Now works on Spigot 1.20+ (previously Paper-only) — runtime detection automatically uses the right serialization format
• Backwards-compatible item storage — existing databases work without migration on either platform
• Folia and Purpur still fully supported

Improvements

• Added background sweep task that removes idle transaction locks every 5 minutes
• Removed unused legacy code paths to reduce footprint
• Added 9 new automated stress tests covering memory leaks, lock contention, and concurrent load (106 total tests)
