Heap Metadata Corruption Manager for Memory Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer applications are prone to hanging or crashing due to corruption issues in heap metadata, which existing technologies cannot effectively resolve, leading to system instability and downtime.
Innovation Solution
A heap metadata corruption manager detects corrupted metadata, creates a new heap in a free memory region, and updates the heap directory to redirect memory allocation calls, thereby preventing further errors and ensuring application availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heap metadata is used to manage memory allocation, then memory management efficiency is improved, but system reliability deteriorates due to metadata corruption causing application crashes
Solution Approach 1:
The patent segments the heap into multiple regions and introduces a heap directory structure that separates metadata management from the actual heap data. The heap directory contains individual entries for each heap region, allowing the system to isolate and manage corrupted metadata at the entry level rather than affecting the entire heap structure. This segmentation enables continued operation of unaffected heap regions even when metadata corruption occurs in one area.
Solution Approach 2:
The patent introduces a heap corruption manager as an intermediary component between the application and the heap metadata. This manager includes a break value generator that creates protective mechanisms and a heap directory updater that mediates access to heap metadata. When corruption is detected, the intermediary redirects operations away from corrupted metadata, preventing crashes while maintaining memory management functionality.
2Device complexity
If existing technologies are used to handle metadata corruption, then implementation simplicity is maintained, but application availability deteriorates due to inability to resolve corruption issues
Solution Approach 1:
The patent implements preliminary protective actions by generating break values and establishing heap directory entries before corruption occurs. The heap corruption manager proactively monitors heap integrity and prepares recovery mechanisms in advance. When corruption is detected, the pre-established heap directory structure and break values enable immediate redirection of memory operations without requiring complex runtime analysis or manual intervention.
Solution Approach 2:
The patent enables the memory allocation system to self-diagnose and self-recover from metadata corruption. The heap corruption manager automatically detects corruption through break value validation, generates appropriate error responses, and updates the heap directory to redirect future operations. This self-service capability eliminates the need for external intervention or complex recovery procedures, maintaining application availability while managing corruption issues.

AI summary
Embodiments are disclosed for managing heap metadata corruption. The techniques include detecting a metadata corruption error in a first heap disposed in a first region of memory. The techniques also include generating a second heap in a free memory region that is disposed beyond a break value address of a memory allocation system. The techniques further include updating a first entry for the first heap in a heap directory. Additionally, the techniques include generating a second entry for the second heap in the heap directory. The techniques also include processing a call to the memory allocation system for the first heap based on the first entry and the second entry.
