Pull Request Summary

Memory Management Project

Overview

This PR includes updates and implementations aimed at improving the custom memory management library. The focus has been on optimizing functionality for malloc, free, calloc, realloc, and memory logging to ensure robust memory operations across various scenarios. The changes include enhanced thread-safety, detailed logging, and efficient memory handling strategies.

Key Features and Changes

1. Memory Allocation (malloc.c):

   • Refactored the my_malloc function for better thread-safety and clearer allocation logic.
   • Added support for dynamic memory extension via extend_heap.
   • Enhanced alignment handling to ensure compatibility with hardware memory requirements.

2. Memory Deallocation (free.c):

   • Improved my_free to handle merging of adjacent free blocks via the fusion function.
   • Ensured proper tracking of freed memory and error handling for invalid pointers.
   • Integrated optional unmapping for releasing memory to the system when required.

3. Zero-Initialized Allocation (calloc.c):

   • Implemented my_calloc, which ensures zero-initialized memory allocation.
   • Addressed edge cases where multiplication of elements and size could cause overflow.

4. Memory Reallocation (realloc.c):

   • Redesigned my_realloc to allocate new blocks only when necessary and copy data efficiently.
   • Utilized a helper function copy_block for safe data transfer between memory blocks.
   • Improved logging for realloc operations to include both old and new block sizes.

5. Memory Logging (mem_logging.c):

   • Added detailed logging of allocation and deallocation operations.
   • Implemented mechanisms to track operation IDs and cumulative memory usage.
   • Ensured logs are safely stored and can be cleaned up after operations.

6. Heap and Metrics Management (memory.c, mem_metrics.c):

   • Provided utilities for checking heap consistency and calculating fragmentation.
   • Integrated tracking for total allocated and freed memory.
   • Added functionality for reporting memory usage in a user-friendly format.

Conclusion

This PR introduces robust memory management capabilities while maintaining clarity and maintainability. While automated testing coverage is moderate, the manual tests provide confidence in the library's reliability and resilience.
