More Info

multithread-inspector

Multithread Inspector is an extension for static analysis and visualization of thread usage and synchronization in C++ code. It helps you understand, debug, and document multithreaded logic by providing interactive thread flow graphs and detailed reports.

Features

  • Thread Flow Graph Visualization:
    Generates an interactive graph showing thread creation, synchronization primitives, and their relationships in your C++ code.

  • Context Analysis:
    Highlights threads created inside loops and conditionals for easier detection of potential concurrency issues.

  • Synchronization Mapping:
    Visualizes usage of mutexes, atomics, condition variables, and other synchronization primitives.

  • Clickable Navigation:
    Click on graph nodes to jump directly to relevant lines in your source code.

  • Textual Reports:
    Provides a summary and detailed report of thread and synchronization usage.

Getting Started

  1. Install the extension from the VSCode Marketplace.
  2. Open a C++ file with threading code.
  3. Run the analysis:
    • Press Ctrl+Shift+T (Windows/Linux) or Cmd+Shift+T (macOS).
    • Or right-click in the editor and select Analyze Thread Flow.
  4. View the results in the "C++ Thread Flow Graph" panel.

Supported Threading Constructs

  • std::thread
  • std::async
  • pthread_create
  • std::mutex, std::lock_guard, std::unique_lock
  • std::condition_variable
  • std::atomic
  • std::shared_ptr (for shared data)
  • Basic detection of thread creation in loops and conditionals

Requirements

  • Visual Studio Code 1.70.0 or newer
  • Works on Windows, Linux, and macOS
  • No external dependencies required

Extension Settings

No custom settings yet. All features work out-of-the-box.

Known Issues

  • Analysis is static and may not detect all dynamic/threading patterns.
  • Complex macro-generated or template-based threading code may not be fully supported.
  • Only basic context analysis for loops and conditionals.

Release Notes

1.0.0

  • Initial release: thread flow graph, context analysis, clickable navigation, and textual reports.

Enjoy using multithread-inspector!
