scaibu_mutex_lock 1.0.10

A Dart package for mutex locking, ensuring safe and efficient synchronization. Supports atomic ops, deadlock prevention, and lightweight resource locking.

Changelog

1.0.0 - 2025-03-14

Added

• Initial release with mutex locking mechanisms.
• Implements Circuit Breaker Mutex, Read-Write Lock, Priority Mutex, and Resource Pool.
• Supports atomic execution and isolate-based execution for concurrency management.
• Includes event queue and awaiting stream utilities.

1.0.5 - 2025-03-22

Added

• Example usage in example/lib/circuit_breaker_example.dart to demonstrate how to use the CircuitBreakerMutex class.
• Unit tests for CircuitBreakerMutex to ensure reliability and correctness.

Fixed

• Resolved a bug related to improper state handling in CircuitBreakerMutex that caused incorrect circuit reset behavior.

1.0.7 - 2025-03-30

Added

• Implemented StorageEngineBloc for managing data operations using BLoC.
• Added support for fetching, saving, deleting, and querying stored items with typed generics (T extends StorableModel).
• Introduced event-driven architecture with event handling for:
  • Loading single and multiple items (LoadItem, LoadItems).
  • Saving single and multiple items (SaveItem, SaveItems).
  • Deleting items based on ID, multiple IDs, or conditions (DeleteItem, DeleteItems, DeleteWhere).
  • Streaming real-time updates for stored data (WatchItem, WatchItems, WatchFilteredItems).
  • Querying stored items based on filter conditions (QueryItems).
  • Managing raw data (SetRawData, GetRawData, WatchRawData).
  • Clearing storage under a specific tag (ClearStorage).

Fixed

• Addressed potential memory leaks by ensuring all stream subscriptions are properly canceled and cleared.

1.0.9 - 2025-04-06

Fixed

• Ensured correct cancellation and cleanup of stream subscriptions in WatchItem<T> event to prevent memory leaks and duplicate listeners.
• Added conditional checks to avoid BLoC method calls (add(...)) after closure, preventing potential runtime exceptions.
• Improved internal _subscriptions map management by consistently removing canceled entries.

• Storage layer enhancements

  • Added app_storage.dart for generic storage handling.
  • Introduced storage_engine.dart with BLoC pattern support.
  • Added storageEngine/ sub-module with:
    • storage_engine_bloc.dart

    • storage_engine_state.dart

• TreeCraft repository

  • Introduced tree_repository/ for tree-based data structures.
  • Added tree_mappable.dart under model/.
  • Added generic_tree_node.dart under service/.

Changed

• Reorganized lib/ structure:
  • Core mutex handling in core/mutex_service.dart
  • Lock implementations moved to src/lock/
  • Mutex implementations moved to src/mutex/
  • Async utilities under src/stream/
  • Shared resources under src/utils/
• Ensured scaibu_mutex_lock.dart acts as a clean public API entrypoint.

Deprecated

• lib/main.dart kept temporarily for compatibility but scheduled for removal.
• lib/example/lib/main.dart (will be migrated to top-level example/ folder in future release).

Fixed

• Improved internal naming consistency (transaction_mutex.dart instead of mutex_transaction.dart).
• Resolved deep nesting in earlier treeCraft and mutexLock directories.
