Bug#1027387: python3-channels-redis: upstream bug: runtimeError: event loop is closed

[Jérémy Lal]

Package: python3-channels-redis
Version: 4.0.0-1
Severity: normal

Hi,

multiple python applications using channels-redis 4.0.0 have that issue:
https://github.com/django/channels_redis/issues/332

It doesn't look like it's going to be fixed soon.
It might be a good idea to not ship channels-redis 4.0.0 in bookworm.

I ran into this too just now, and it was very confusing. I was able to
work around it by switching to RedisPubSubChannelLayer, but I'm not
totally sure that's a good idea: it's still marked as being in beta even
now, 4.0.0's RedisPubSubChannelLayer also suffers from
https://github.com/django/channels_redis/issues/343, and in my
application the switch provoked some kind of extremely weird coverage
failure, possibly https://github.com/python/cpython/issues/106749.

Since there is now an upstream fix
(https://github.com/django/channels_redis/pull/347), I think it would be
worth backporting this to bookworm.

I've filed https://bugs.debian.org/1064276 to request permission to
upload this.
