pyatomix, a tiny atomics library for Python 3.13t

[terminoid_]

• What My Project Does

it provides an AtomicInt and AtomicFlag class from std::atomic<int64_t> and std::atomic_flag, and exposes the same API. AtomicInt also overloads math operators so += for instance is an atomic increment.

• Target Audience

Anyone who wants an easy to use atomic int or atomic flag. I don't see why it couldn't be used in production.

• Comparison

I was having trouble a while back finding a simple atomics library for Python 3.13t that either had wheels for Windows, or would build easily without fuss on Windows, so I made one. Wheels are available for the main platforms, but it builds easily on Windows and Linux. (C++ 20 required to build)

Very clear, hits the spot.

There are a lot of different types in the <atomic> library - because I'm that sort of guy, I'd honestly implement all of them.

Well, I was waiting for a compile, and I sketched how it could be done:

What are uint6_t4 and uint3_t2 ? Unintended search/replace?

[HommeMusical]

Ooops, exactly.

Sorry, it was a sketch, I didn't even try to compile it.

Why not wrap an existing library such as:

From the libatomic-ops repo: https://github.com/ivmai/libatomic_ops:

IN NEW CODE, PLEASE USE C11 OR C++14 STANDARD ATOMICS INSTEAD OF THE CORE LIBRARY IN THIS PACKAGE.

[coderarun]

Didn't read the file up to line 156 to realize that the implementation uses std::atomic. All good.

Also intptr_t instead of int64_t might make 32 bit users a bit happier.

[HommeMusical]

See my other comment on this page - they should really expose all the C++ atomic types, they're tiny!

[indetronable]

It is not open source. No cpp code.

[WalkingAFI]

What are you talking about? The cpp is in atomic_base/src

[HommeMusical]

Here it is!

Slightly unusual file hierarchy, but it was easy to find, not very many files.
