aiostarter does not work
it seems like it's not picking up the settings in the development.ini but I dont know why that would be.

aiopyramid.exceptions.ScopeError:
Synchronized coroutine <function DefaultViewMapper.map_nonclass_requestonly.<locals>._requestonly_view at 0x7f58ca9d0ef0> called in the parent
greenlet.
This is most likely because you called the synchronized
coroutine inside of another coroutine. You need to
yield from the coroutine directly without wrapping
it in aiopyramid.helpers.synchronize.
If you are calling this coroutine indirectly from
a regular function and therefore cannot yield from it,
then you need to run the first caller inside a new
greenlet using aiopyramid.helpers.spawn_greenlet.

and checking the source code, ReadBuffer hasn't been in the wsgi module since 0.8.0 (march of 2018)
https://github.com/etianen/aiohttp-wsgi/compare/0.5.2...0.8.0
So what's going on here? is this still maintained? I know there's been a bit of churn in the past in regards to asyncio and probably aiohttp. But I just want to get websoockets working in pyramid.
Seems like gunicorn now essentially requires you to use pserve if you are going to use paste. https://docs.gunicorn.org/en/stable/run.html#paste-deployment. It will no longer respect the server definition from the paste config unless invoked with pserve:
but Gunicorn will not use any server configuration defined in the file
I was not able to replicate your import error, pserve worked for me. Have you tried configuring gunicorn separately?
The changes in gunicorn invalidate the getting started section of the docs as well as aiostarter.
@housleyjk Hi Jason
Im dealing with the same error : class uri 'aiopyramid.gunicorn.worker.AsyncGunicornWorker' invalid or not found: Caused by: ImportError: cannot import name 'ReadBuffer' from 'aiohttp_wsgi.wsgi' (/home/xxxxx/xxxxxx/venv/lib/python3.7/site-packages/aiohttp_wsgi/wsgi.py)
Tried both with python 3.11 & 3.7 same issue.
After checking aiohttp-wsgi repo 'ReadBuffer' class seems to be missing, causing error when gunicorn start with:
worker_class = aiopyramid.gunicorn.worker.AsyncGunicornWorker
If used without worker class it works fine.
Last commit contained related class was : https://github.com/etianen/aiohttp-wsgi/commit/dd984417eacce2a52329db0440ce95ef294608d7
Any idea how to fix that ?
