Nuitka8.1 with Sanic，RuntimeWarning: coroutine 'BaseEventLoop.create_server' was never awaited

[HB4daemmon]

I freeze a simple sanic project with nuitka on windows11, but it doesn't work correctly。

You didn't see this, did you OSError: could not get source code. It seems it wants to check source code for whatever reason, any idea why?

Yes, you are right. I checked Sanic souce code and found "touchup" modules load source code. I changed some configuration and now it works. Thanks for checking this.

app.config.TOUCHUP = False

[kayhayen]

What is this touchup for?

Over @ Linux (ubuntu 22.04 lts), I'm getting a different error:

FileNotFoundError: [Errno 2] No such file or directory: 'main.dist/sanic_ext/extensions/openapi/ui/redoc.html'

If I copy in the stuff requires from site-packages (basically the whole sanic_ext package) manually I get the same error as above.

[Pirulax]

OP's error

Adding the following argument when running Nuitka should help:

--include-data-dir=".venv/lib/python3.10/site-packages/sanic=sanic"

The actual path to your sanic installation may very, in my case I have it inside my venv.

My issue (above)

FileNotFoundError: [Errno 2] No such file or directory: 'main.dist/sanic_ext/extensions/openapi/ui/redoc.html'

This should only happen if you have the sanic_ext package installed too. It happens because Sanic tries generating the openapi docs. It can be solved in 2 ways:

• Either copy the whole sanic_ext package into the output folder (the one ending with .dist, eg.: main.dist)
• Or just disable it altogether:

app = Sanic("ur-app")
app.extend(config={"oas": False})

Thanks for the help from the guys over at the Sanic Discord, especially to Adam Hopkins.

[kayhayen]

Manual copying is not supported at all. Rather than using paths, using --include-package-data would make more sense. If somebody figures out, which files to add, please add them to the Nuitka package configuration file as Yaml.

[kayhayen]

@Pirulax if that's a default, anti-bloat and the Yaml configuration could make that change automatically, because I doubt people want that to happen

[kayhayen]

This will make it straight to 2.0.2 too, once released, hopefully soon.

[Pirulax]

Great, thank you very much for the effort!

hadn't noticed this comment, in order to reproduce, is all that's needed is for the sanic_ext package to be available? or do i have to take other steps to reproduce?

[Pirulax]

I don't remember it anymore sadly. but iirc you just have to install sanic_ext and that's it (and perhaps import it in the py code)

[kayhayen]

Copying anything was never supported or supposed to work, so lets not consider that at all. For the generation of docs, that probably needs to be disabled, if that's the case that it does this on the side, typical anti-bloat. So was I closing this prematurely or does it work for you @KevinRodriguez777 ?

[KRRT7]

For the generation of docs, that probably needs to be disabled

i don't think so, if it does something like FastAPI openAPI swagger docs generation, then it probably shouldn't be disabled as it's an feature

So was I closing this prematurely or does it work for you @KevinRodriguez777 ?

no i think you're fine, the sanic_ext is basically a different package and i'll include the datafile later on

[KRRT7]

something like FastAPI openAPI swagger docs generation

[2024-02-11 02:01:36 -0500] [16896] [INFO] > openapi [http://0.0.0.0:8000/docs] yup. that's exactly what's happening, after looking at the HTML file itself, it's a template that gets edited with the generated HTML that it needs to serve the OpenAPI docs.

[kayhayen]

Ok, I will not look deeply into these things, I trust you will handle it.
