Support for Python 3.11

[etseidler]

Are there any plans to support Python 3.11?

I ran my app's test suite after bumping Python from 3.9.7 to 3.11.0 and got a bunch of the following:

pony.orm.decompiling.DecompileError: Unsupported operation: RETURN_GENERATOR

Hi,

I'm using Mutmut project for my mutation tests. This project uses Pony and since I upgraded from python 3.10.1 to python 3.11.0 I have the same issue

pony.orm.decompiling.DecompileError: Unsupported operation: RETURN_GENERATOR

to reproduce it with mutmut, just run mutation testing in order to get a .mutmut-cache (SQLite file) and run mutmut html (without error you should get an html report)

Best regards

Is there are full traceback available?

In my case (with mutmut)

$ mutmut html

https://docs.python.org/3/library/dis.html#opcode-RETURN_GENERATOR seems to be the new addition to the python bytecode.

python/cpython#90567 for the issue with more information.

Here's a complete tracelog of the testsuite failure running 3.11, it can help.

I installed it with pip install git+https://github.com/jspricke/pony@py311, still get pony.orm.decompiling.DecompileError: Unsupported operation: RESUME when performing .order_by(lambda m: m.created)]

I can confirm lambdas don't work under Python 3.11 on the latest Pony version

Ran into the same while trying to use mutmut.
