v1.0.0-rc1 – Feature Complete Candidate

🚀 Release v1.0.0-rc1 – Feature-Complete Candidate

This is the first release candidate of 2024_Research_MassifCheck, a fully functional Qt desktop application for profiling and analyzing heap memory usage using Valgrind Massif.
All core features are implemented, and this version is submitted for academic review.

---

✨ New Features

• Configurable Thresholds via GUI:
  Thresholds for memory analysis are now fully customizable through the Settings window, replacing previously hardcoded values.

• Extended Heap Analysis Heuristics:
  Added multiple new analysis rules:

  • Total memory allocated per function
  • Number of allocation calls per function
  • Detection of memory fragmentation (based on useful_heap vs total heap)
  • Identification of many small allocations
  • Detection if a function allocated a large amount of memory
  • Based on the final snapshots, the program estimates whether memory has been properly freed by the end of execution
  • Recommendations based on these metrics

• Detailed Allocation Summaries:
  Extracted AllocationEntry structures summarize per-function allocation stats: how much, how often, and what kind of allocations were made.

• Compile & Run Flow:
  When selecting a .c or .cpp file, the app compiles it and automatically runs it with Valgrind Massif using the current or default options.

---

🎨 UI & UX Improvements

• Persistent Settings & Thresholds:
  User-selected options and thresholds are now remembered across sessions. The Settings dialog reflects the current configuration when reopened.

• Improved Result Dialog Feedback:
  Messages returned after Massif analysis are now grouped into:

  • Errors
  • Informational insights
  • Optimization recommendations

---

🧰 Project Updates

• Updated README.md
• Added Usage Guide on the project Wiki
• Cleaned up error messaging and internal logic

---

⚠️ Known Limitations

• Tested on Windows 10/11 with WSL2 + Ubuntu 22.04
• Valgrind is only available via Linux/WSL, not natively on Windows
