Domino Library

A small C++17 library.

Talk is cheap. Let $\color{red}{\textsf{AI}}$ show you the library details:

• What it does
• How it works
• Quality/proficiency, e.g.:
  • AI benchmark: Give Claude Opus 4.5 only SafePtr's UTs and ask it to produce its best implementation that passes every test. Then compare the generated implementation with the existing code under the same rubric. Result in my run: existing SafePtr 92/100; Opus baseline 68/100.

Components

• Domino

  • Problem: such as OS-upgrade, involves many interdependent conditions & tasks.
  • Each condition is a domino tile, and their dependencies form a DAG.
  • A condition satisfied = a tile falls → auto-broadcasts to downstream (domino).
  • A task can stick to 1 tile - when the tile falls, auto-execute the task.
  • Result: improved eNB-base-station-upgrade $\color{blue}{\textsf{from}\sim9\textsf{min to}\sim1\textsf{min}}$.

• ObjAnywhere:

• MsgSelf is a priority FIFO queue.

• SafePtr is safer than std::shared_ptr.

• SmartLog

• ThreadBack: time-cost event running in a separate thread → callback main thread.

Engineering

• ut/ each UT case is an end-to-end scenario.
• GitHub Actions runs GoogleTest under Valgrind on pushes, pull requests, and a weekly schedule.
• High line & branch coverage.
• The currently verified CI environment is Ubuntu + GCC.

Build and Run

Requirements: CMake 3.14 or newer and a C++17-capable compiler.

Ask AI for details.

Contributing

Issues and pull requests are welcome. Changes should include or update unit tests; the existing tests are the primary usage examples.
