py*-dnspython 2.7.0 needs py*-sniffio 1.3.1

[marka63]

dnspython 2.7.0 fails because it can't find thread_local in sniffio which is new in 1.3.0 and has a fix in 1.3.1. See ​https://sniffio.readthedocs.io/en/latest/history.html

Missing minimum version dependancy for dnspython

Upgrade of sniffio to support thread_local

This dependency is not declared upstream. See: ​https://github.com/rthalley/dnspython/blob/main/pyproject.toml

I will open an issue.

[Schamschula (Marius Schamschula)]

Apparently sniffio was removed in ​https://github.com/rthalley/dnspython/commit/063bd7fa084301bd3c232bfdbd375780963b356f

[Schamschula (Marius Schamschula)]

However, I can't find bin/tests/system/cookie/ans9/ans.py on my system, and, hence, cannot reproduce the issue locally before reporting it.

Replying to Schamschula:

It was attempting this list of imports:

Replying to Schamschula:

It's part of bind9's test system.

[Schamschula (Marius Schamschula)]

I have bind9 installed. However, this test is only available in the bind9 source code.

I get

python /opt/local/var/macports/build/_opt_local_var_macports_sources_github.com_macports_macports-ports_net_bind9/bind9/work/bind-9.20.2/bin/tests/system/cookie/ans9/ans.py
Traceback (most recent call last):

    query4_udp1.bind((ip4_addr1, port))
OSError: [Errno 49] Can't assign requested address

So perhaps, py-sniffio was picked up silently.

[Schamschula (Marius Schamschula)]

This problem is a simple one: my local repository was ahead of MacPorts master:

port list py-sniffio
py-sniffio                     @1.3.1          python/py-sniffio
py-sniffio                     @1.2.0          python/py-sniffio

I've pushed it. See: [9d56290f80754da55f836ca6c5c587cc630d4693/macports-ports]

[marka63]

Thanks.

On further reflection the missing version dependancy is with py*-trio rather than py*-dnspython. Somewhere between py310-trio 0.22.2 and py310-trio 0.23.2, py-sniffio 1.3.1 became required.
