AsyncClient gives TrioDeprecationWarning

[p-i-]

The following testcase gives a warning:

import trio, httpx

async def amain():
    async with httpx.AsyncClient() as client:
        r = await client.get('https://icanhazip.com/')
        print(r.text)

trio.run(amain)

Output:

> python  test.py

/Users/pi/code/test/.venv/lib/python3.10/site-packages/anyio/_backends/_trio.py:164: TrioDeprecationWarning: trio.MultiError is deprecated since Trio 0.22.0; use BaseExceptionGroup (on Python 3.11 and later) or exceptiongroup.BaseExceptionGroup (earlier versions) instead (https://github.com/python-trio/trio/issues/2211)
  class ExceptionGroup(BaseExceptionGroup, trio.MultiError):

So I'm on the latest trio (as per https://pypi.org/project/trio/) and latest httpx (as per https://pypi.org/project/httpx/)

Presumably httpx needs to be somehow patched to handle a new construct in trio 0.22.0

What's my best play here? Simply supress the warning? (and if so, how?).

(Note: As can be seen from the output, the code still works, I'd just like to not have the warning).

This is because AnyIO 3.x still uses the old MultiError construct directly with the trio backend. This has already been rectified in master, and will be part of the 4.0 release later.

This prevents the warning from showing:

import warnings
from trio import TrioDeprecationWarning
warnings.filterwarnings(action='ignore', category=TrioDeprecationWarning)
