Investigate errors in daily Python 3.7 and Python 3.10 errors

[swcurran]

We are running the integration tests for Python 3.6 - 3.10 and currently we are getting errors for Python 3.7 and Python 3.10.

Investigate the errors and solve at least the 3.10 issue, and ideally both.

@Jsyro — here is the task for you to look at. I’ll see if I can make you an assignee, and will be adding you to the Hyperledger organization so that for sure you can be added to future tickets.

Initial investigation:

3.10 (INDY and normal), assertion library TypeError: required field "lineno" missing from alias. possible breaking change or library dependency issue.

3.7 (INDY and normal), Flake 8 is checking and thinks it's finding attribute errors, maybe it's legit, but probably there is a type checking issue with this error.E AttributeError: 'EntryPoints' object has no attribute 'get'

TypeError: required field "lineno" missing from alias was fixed with an update to the pytest library.

pytest-dev/pytest#9195.

The code uses the asynctest package which has not been updated since May 2019, https://pypi.org/project/asynctest/#history.

Which internally uses deprecated version of defining async functions. The 3.8 and 3.9 test results include the relevant deprecation warning to use async def instead.

Rapptz/discord.py#375 (comment)

Looks like we will need to refactor out that library for find a suitable replacement.

Ouch — that sounds terrifying. See image:

Tests rely on this library, https://github.com/nvllsvm/async_case.... which is incompatible with newer versions of asyncio that do not accept the loop parameter in the gather() method.

https://docs.python.org/3.10/whatsnew/3.10.html#changes-in-the-python-api

Unsure how to proceed, could update the lib, but unclear if that would break older versions, could refactor and remove dependency on the library, but the related tests are quite dense.
