Test failures with Python 3.12.0b2

[hrnciar]

Describe the bug

Hello, I am experiencing test failures with Python 3.12.0b2. yarl was working with 3.12 up until the 7th alpha. I've consulted this with @encukou and it is happening because of changes in CPython. He will provide more context.

To Reproduce

Build yarl with Python 3.12.0b2.

Expected behavior

All tests pass successfully.

@mjpieters could you cut a new release? I'm on vacation and won't be completing the packaging remake this week.

[yuzibo]

Hi,
any progress on this?
There is a RC bug from Debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1042342

And I can confirm the issue is in 1.9.2 also.

[commonism]

Affects python3.11 and at least yarl 1.8.2-1.9.2.
HEAD is fine

[webknjaz]

v1.9.3 is out:

• https://pypi.org/project/yarl/1.9.3/
• v1.9.3 #957
• https://github.com/aio-libs/yarl/releases/tag/v1.9.3
