OLSRT — A C11 Concurrency Runtime with Actors, Channels, and an Event Loop
Описание и применение
OLSRT объединяет основные парадигмы конкурентного программирования в одном C11‑библиотеке, устраняя необходимость в повторном написании epoll‑обёрток, пулов потоков и других вспомогательных компонентов. Тесты и демо подтверждают корректность работы.
Задача
Developers writing concurrent C on Linux repeatedly re‑implement epoll wrappers, thread pools, lock‑free queues, promises, and shutdown logic, leading to duplicated effort and inconsistent quality.
Результат
OLSRT consolidates common concurrency primitives into a single, well‑tested C11 library, reducing duplication and improving reliability. The test suite and demos confirm correct operation, and the library is easy to integrate.
Рабочий процесс
- Clone the OLSRT repository
- Build the library with "make linux"
- Run the test suite with "python3 verify.py" to ensure ASan, UBSan, and TSan pass
- Use the provided demos in the demos/ directory to validate functionality
- Integrate OLSRT primitives into your project by linking against the library and including the appropriate headers
Доказательства
Four years ago, if you wanted to write concurrent C on Linux, you ended up writing the same code over and over: an epoll wrapper, a thread pool, a lock-free queue, a promise type, and a way to shut all of it down cleanly without leaking.
OLSRT is our answer to that. It is an Apache-2.0 C11 runtime that ships all of those primitives in one place, with a coherent ownership model and a single event loop that ties them together.
The previous release shipped without a test suite and, as we later discovered, with eleven real bugs. We spent a week writing regression tests before touching any of them.
Demo 02 ran 1,000,000 messages through a 1024-slot channel on an AMD E2-1800 (dual-core, 1.7 GHz) at roughly 386,000 msg/s.
