Bug: CI VS tests failing due to redis-py regression

Description of the bug

VS tests started failing after redis-py 7.2.0 was released on Feb 16, 2026. The new version added OpenTelemetry instrumentation that unconditionally accesses conn.port when recording metrics, but UnixDomainSocketConnection (used for Unix socket connections in VS tests) doesn't have this attribute. This causes an AttributeError and test fails.

This affects all repositories running VS tests that install redis without version pinning:

• sonic-swss
• sonic-sairedis
• sonic-swss-common

I have filed issue & PR in redis-py this morning: redis/redis-py#3958

Steps to Reproduce

File a PR in sonic-sairedis or sonic-swss and see vs tests fail.

Fail message is:

Bash exited with code '123'

Look up AttributeError in the logs, should see something similar to:

AttributeError: 'UnixDomainSocketConnection' object has no attribute 'port'

Actual Behavior and Expected Behavior

Actual behavior: vtests fail
Expected Behavior: vtests should not fail

Relevant log output

An example PR blocked is sonic-net/sonic-sairedis#1751

A workaround would be pinning the redis python client version to be under 7.2.0.

Waiting for a day to see if redis-py addresses the issue raised. If it's not fixed tomorrow I'll be filing PRs in the impacted repositories.

Update: Upstream fix was created and merged (redis/redis-py#3971 closed sonic-net/sonic-sairedis#1751), but don't think a new release is coming out that soon (judging from history it's usually a week or more).

Making PRs now. Probably still worth it to pin the Redis versions.

[Bojun-Feng]

Seems like there is already a solution installing redis from Debian:

Repository	Existing PR
sonic-swss-common	sonic-net/sonic-swss-common#1154
sonic-sairedis	sonic-net/sonic-sairedis#1777
sonic-swss	sonic-net/sonic-swss#4241

Tracking it here. Would appreciate getting them merged as there are multiple PRs being blocked

All three fixes are merged, closing this issue
