Memory Leak Detector
This project is a diagnostic tool and memory profiler designed to identify and track memory allocation patterns within native code layers. It functions as a native code debugging utility that monitors heap usage and resource lifecycle management to assist in the resolution of memory leaks and resource exhaustion issues.
The tool utilizes hook-based allocation interception to maintain a real-time map of active memory blocks and employs shadow-stack call tracing to associate these blocks with specific code locations. By performing periodic reachability analysis and differential memory snapshotting, it isolates persistent memory regions and translates raw addresses into human-readable function names and file paths using embedded debug information.
These capabilities support performance optimization and memory management for native C and C++ components, particularly within the context of Android application development. The utility provides the necessary observability to track resource allocation across native layers, helping to maintain system stability and reduce memory footprints on resource-constrained devices.
Features
- Memory Profilers - Provides a performance analysis utility for monitoring heap usage and resource lifecycle management within native application layers.
- Allocation Interceptors - Intercepts memory allocation and deallocation calls at the system library level to maintain a real-time map of active memory blocks.
- Memory Leak Detection - Identifies and tracks memory allocation patterns in native code to resolve leaks and improve application stability.
- Native Leak Detectors - Tracks resource allocation patterns across native code layers to identify memory leaks and resolve underlying issues.
- Native Debugging Sessions - Pinpoints memory management errors and resource exhaustion issues in low-level software components.
- Android Performance Optimizations - Analyzes resource allocation patterns in mobile applications to reduce memory footprint and ensure smooth performance on resource-constrained devices.
- Heap Allocation Call Stack Recorders - Records the execution path of every allocation request by unwinding the stack to associate memory blocks with specific code locations.
- C++ Memory Management - Tracks heap allocations and deallocations in native C++ code to identify dangling pointers and unfreed memory blocks.
- Runtime Reachability Analyzers - Traverses the object graph at set intervals to identify memory segments that are no longer referenced by any active application component.
- Symbolic Backtrace Resolutions - Translates raw memory addresses into human-readable function names and file paths using embedded debug information.
- Heap Snapshot Comparison - Identifies growing memory regions by calculating the difference between successive heap snapshots.
