Please make a new release

[mgorny]

Could you please make a new release? I'm specifically looking for the async_generator dependency being removed, as that should be good enough to enable Python 3.12 support in the Gentoo package.

Hi, I've been aiming for a release soon after 3.7 is no longer in our compatibility window (~a month), would that work?

Additionally, is async-generator really the only thing broken for 3.12? We have a bunch of test cases failing there, detailed in #2646. (Just checking if those matter!)

I've seen only 1 new test fail on Gentoo compared to Python 3.11 (trio/_core/_tests/test_run.py::test_nursery_cancel_doesnt_create_cyclic_garbage). I'm yet to see in greater detail but it seems good enough for httpx at a first glance.

I'm currently playing with a snapshot from current git, so hopefully that'll be good enough before the next release.

Hi, would it be possible to publish a new release before waiting for the support end of Python 3.7? I don't care about 3.7, but the last release of trio was in September of last year, which is quite a while.

I'm specifically looking for support for generic typing of MemorySendChannel/MemoryReceiveChannel which was added in #2549 in February.

The most recent release of trio-typing already defines

class MemorySendChannel(trio.abc.SendChannel[T_contra]): ...
class MemoryReceiveChannel(trio.abc.ReceiveChannel[T_co]): ...

This just bit me a bit as a new user of trio, because I thought that this was supported. Right now I get this error when trying to implement generic memory channels:

TypeError: <class 'trio.MemorySendChannel'> is not a generic class

class EventListener(Generic[TEvent]):
    sender: trio.MemorySendChannel[TEvent]
    receiver: trio.MemoryReceiveChannel[TEvent]
    ...

Installing trio from git is not an option for me, so I'm kindly asking for a new release. Thanks!

3.7 EOL is in two weeks. I won't personally be able to roll a new release before that, but maybe someone else will.

You can use from __future__ import annotations to resolve the MemoryXyzChannel-not-generic error.

Are there any blockers / particular issues that should be merged before release @A5rocks?

[A5rocks]

Only #2674! merged

[A5rocks]

Oh yeah, and pylint failing on pypy-3.7 isn't great, since the required checks need to pass before releasing. I've left a comment on #2669 cause I think you could xfail it there or maybe you (or I) could make a seperate PR.

Fixed in #2676
