AttributeError: module 'boros' has no attribute 'run'

[user451421541757324]

Hello, I am trying to use boros but without success.

mkdir test
cd test
python -m venv .
git clone https://github.com/vbe0201/boros
cd boros
../bin/python -m pip install .

This is the line:

import boros

...

if __name__ == "__main__":
    boros.run(main())

But then I get the error module 'boros' has no attribute 'run'.

I also tried an installation with uv, as written in the README, but I get the same error.

I'm not a Python expert (maybe I did something wrong during installation), I just wanted to play around with io_uring a little.

Hi there, your installation process is fine but boros is still in a very early state and an asyncio-like run() isn't supported yet.

The latest commit introduces some initial capabilities for playing with asynchronous I/O if that's interesting to you:

from boros._low_level import *

p = EventLoopPolicy()
p.sq_entries = 8

l = create_event_loop(p)

# nop() queries an io_uring nop operation and tick()
# waits for its completion and prints a result.
nop(1)
l.tick()
nop(2)
l.tick()
nop(3)
l.tick()

If you're interested in hacking on it be my guest but otherwise this library isn't useful yet. I can notify you when that changes.

My bad, I saw the code in DESIGN and thought it was working.

Thanks for the offer, but this stuff is too advanced for me 😂.

I will wait until the work is finished (I saved the repo). I'm looking forward to it, as this seems to be the only attempt to make Python work with io_uring. The other (very few) projects I've tried are either abandoned or don't work.

Thank you for your quick response and for your work.

Yeah to my knowledge the other projects are either abandoned or don't make good use of many of the cool features io_uring offers. liburing could work for you but the API is low-level and requires some time to get used to it.

I will leave this issue open until I think boros is ready for practical use. 👍
