- Add new benchmarks and unit tests for parallel collections
- Misc: add MemoryUtility.AlignUp, version bumps, test improvements, bug fixes
Replaced the deprecated Allocator API with the new AllocationHandle API across the codebase. Updated constructors, methods, and tests to use AllocationHandle for memory management. Marked Allocator-based methods as [Obsolete] and provided alternatives.
Added OwnershipTransferAnalyzer to detect ownership transfer issues and introduced OwnershipTransferAttribute for marking parameters. Enhanced DefensiveCopyAnalyzer with additional checks for readonly and ValueType instances.
Refactored internal memory management in AllocationManager and updated benchmarks, utilities, and documentation to reflect the changes.
BREAKING CHANGE: Deprecated Allocator API in favor of AllocationHandle. Updated constructors and methods to use AllocationHandle. Users must migrate to the new API.
Refactored memory management by removing safety checks and introducing `MemoryHandle` for centralized tracking. Simplified allocation logic across allocators and enhanced `Dispose` methods for better resource cleanup.
Added `UnsafeChunkedQueue<T>`, a lock-free, dynamically resizing queue with chunk-based memory management, supporting parallel producers and consumers.
Updated unit tests to validate new queue functionality and ensure compatibility with refactored memory logic. Incremented assembly version to 1.6.12.
BREAKING CHANGE: Removed `#if MHP_ENABLE_SAFETY_CHECKS` blocks, altering memory validation behavior.
Refactor all unsafe collection enumerators to use ref struct types,
removing support for boxing and standard .NET enumeration interfaces.
GetEnumerator methods now return stack-only, more efficient enumerators
with [UnscopedRef] and inlining attributes. IEnumerable<T> and
IEnumerable implementations are removed from affected types. Interfaces
now require unmanaged types. Also includes minor doc and bug fixes.
BREAKING CHANGE: Enumerators are no longer compatible with LINQ, and collections no longer implement IEnumerable/IEnumerator.
Added debug-only checks in Dispose methods of HashMapHelper, UnTypedArray, and UnsafeArray to log a message (with optional stack trace) if Dispose is called on an uninitialized or already disposed instance, unless the buffer is null. Incremented assembly version to 1.6.6.
Enhanced Dispose() in HashMapHelper, UnTypedArray, and UnsafeArray<T> to provide more informative debug messages when called on uninitialized or already disposed objects. When MHP_ENABLE_STACKTRACE is defined, the debug output now includes a stack trace with file, type, method, and line number details.
Also incremented project version to 1.6.5.
Add AllocationManager.GetTotalAllocatedMemory() to track total allocations when safety checks are enabled. Improve diagnostics by calling Debug.Fail in Dispose methods of HashMapHelper, UnTypedArray, and UnsafeArray when disposing uninitialized or already disposed arrays. Remove AddRange(ReadOnlyUnsafeCollection<T>) from UnsafeList<T>. Increment assembly version to 1.6.4. Ensure arrcpy is disposed in Program.cs.
Refactor to use MHP_ENABLE_SAFETY_CHECKS, MHP_ENABLE_STACKTRACE, and MHP_ENABLE_MIMALLOC for feature toggling. Remove FreeList allocator in JobSchedular and debug-layer code, simplifying memory management. Improve memory leak detection and reporting, update memory allocation API, and guard all safety/debug features with new defines. Update csproj files, README, and code samples to match new API and toggles. Fix and improve collection types for correct behavior with and without safety checks. The codebase is now more modular and easier to configure for different build environments.
BREAKING CHANGE: Old defines (ENABLE_SAFETY_CHECKS, ENABLE_DEBUG_LAYER, ENABLE_MIMALLOC) are replaced with MHP_* equivalents. FreeList allocator and related debug features are removed. Some APIs and behaviors have changed for safety/debug configuration.
Introduce VirtualStack allocator, refactor memory management to use virtual memory stacks, and update documentation.
Added VirtualStack as a new stack allocator using virtual memory, replaced Stack with VirtualStack in allocation manager and related APIs, and updated TempJobAllocator to use VirtualArena. Introduced AllocationManagerInitOpts for allocator configuration. Replaced ENABLE_COLLECTION_CHECKS with ENABLE_SAFETY_CHECKS for safety checks. Removed Result.cs and updated project files and examples. Added comprehensive README files for all major packages and improved root documentation.
BREAKING CHANGE: Stack allocator replaced by VirtualStack; TempJobAllocator and AllocationManager initialization signatures changed; Result types removed.
Refactored FreeList allocator to use per-thread caches for improved scalability and performance, with configurable max concurrency and overflow cache. AllocationManager debug layer is now compile-time via ENABLE_DEBUG_LAYER. MemoryUtility methods no longer catch exceptions. Argument validation standardized with ThrowIfNegative. JobScheduler passes maxConcurrencyLevel to allocator. CollectionUtility's GetElementUnsafe returns mutable ref. AssemblyVersion incremented. Added comprehensive FreeList unit tests. Improved robustness and error handling in allocation classes.
BREAKING CHANGE: Debug layer APIs removed; FreeList allocator interface changed for thread cache support.
