…@v6 and rand v0.10
…s; update documentation and examples
- Consolidated slab allocator benchmarks into a single file, removing redundant code and improving organization. - Removed the stability.rs file, which contained stress tests that are now integrated into the stress_test.rs file. - Introduced a new stress_test.rs file to handle various stress scenarios, including random mixed allocations, exhaustion recovery, and fragmentation recovery. - Updated README.md to reflect changes in the test structure and added instructions for running stress tests. - Removed the test_composite_page_allocator_alloc_at function from integration_test.rs as it was not providing meaningful validation.
…omponents; simplify allocation logic
- Introduced a MockOs struct to simulate CPU context switching in tests. - Updated integration tests to use the new MockOs for cross-CPU allocation and deallocation scenarios. - Refactored memory allocation and deallocation functions for better clarity and reuse. - Enhanced stress tests to utilize the MockOs for simulating multi-CPU environments. - Improved error handling and assertions in tests to ensure robustness. - Removed redundant code and comments for cleaner test files.
- Updated integration tests to use BuddyAllocator and SlabAllocator. - Replaced MockOs with TestOs for better clarity in test context. - Simplified memory allocation and deallocation functions. - Enhanced test cases for buddy allocator, including basic allocation, alignment, exhaustion recovery, and fragmentation recovery. - Improved stress tests to ensure allocator stability and recovery from exhaustion. - Removed unused code and comments for better readability.
…alization - Updated benchmarks in `benches/slab_allocator.rs` to use the `divan` framework, simplifying the allocation and deallocation logic. - Removed redundant code and improved clarity in benchmark functions for size class allocation, hot reuse, mixed size batch, and steady state recycling. - Enhanced the `GlobalAllocator` in `src/global.rs` to manage metadata layout more effectively, ensuring proper alignment and size calculations. - Modified the `BuddyAllocator` to enforce stricter checks during deallocation, ensuring that the correct block sizes are freed. - Improved error handling in tests to validate allocator behavior under various conditions, including unaligned region starts and insufficient managed pages. - Cleaned up memory allocation and deallocation logic in stress tests, removing unnecessary metadata handling.
…ees and add integration tests for cross-CPU deallocation
…ead of separate start and size parameters
- Removed the MockOs struct and its implementation, simplifying the test setup. - Introduced HostRegion for managing heap memory in tests. - Updated allocation and deallocation logic to use usize pointers instead of NonNull. - Added multithreaded stress tests for mixed allocation/freeing, remote freeing, page allocation/freeing, fragmentation recovery, and exhaustion recovery. - Enhanced assertions to check for recovery with cached slabs. - Improved random allocation logic and CPU management in tests.
- Introduced `BuddySection` and `ManagedSection` to manage multiple memory regions. - Updated `GlobalAllocator` to compute and manage metadata for multiple sections. - Modified allocation and deallocation methods to work with sections. - Enhanced tests to validate behavior with multiple regions, including allocation, deallocation, and memory management. - Added stress tests for concurrent allocation and region addition.
