fix.md

Option A — Upgrade to fixed release\npip install redis==7.1.0\nWhen NOT to use: This fix should not be applied if the application relies on the original function signature of bool_ok.\n\n

Why This Fix Works in Production

Trigger: TypeError: bool_ok() got an unexpected keyword argument 'get'
Mechanism: The bool_ok function did not accept additional keyword arguments, causing a TypeError during cluster rebalancing
Why the fix works: Allows the parsing of the asking command to forward original options, resolving a TypeError during redis cluster rebalance operations. (first fixed release: 7.1.0).

Production impact:

If left unfixed, the same config can fail only in production (env differences), causing startup failures or partial feature outages.

Why This Breaks in Prod

Shows up under Python 3.5.1 in real deployments (not just unit tests).
The bool_ok function did not accept additional keyword arguments, causing a TypeError during cluster rebalancing
Surfaces as: TypeError: bool_ok() got an unexpected keyword argument 'get'

Environment

Python: 3.5.1

What Broke

SET commands with GET option fail during cluster rebalancing, leading to operational disruptions.

Why It Broke

The bool_ok function did not accept additional keyword arguments, causing a TypeError during cluster rebalancing

Fix Options (Details)

Option A — Upgrade to fixed release Safe default (recommended)

pip install redis==7.1.0

When NOT to use: This fix should not be applied if the application relies on the original function signature of bool_ok.

Use when you can deploy the upstream fix. It is usually lower-risk than long-lived workarounds.
