Fix type hints for register_script to support RedisCluster #3876
Conversation
Update type annotations in Script, AsyncScript, and their corresponding register_script methods to accept both Redis and RedisCluster types. This fixes mypy errors when calling register_script on RedisCluster instances. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Hi @majiayu000, thank you for your contribution! We will take a look at it soon. |
Add tests to verify that Script and AsyncScript classes accept RedisCluster as registered_client, validating the type hints fix for register_script to support RedisCluster. - test_script_with_cluster_client: Tests sync Script with RedisCluster - test_async_script_with_cluster_client: Tests AsyncScript with RedisCluster 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

I've proactively added tests for the type hints fix:
These tests verify that the type hints fix works correctly for both sync and async implementations. |
- Fix ruff format issue in AsyncScriptCommands.register_script by putting Union type hint on single line - Fix test_script_with_cluster_client and test_async_script_with_cluster_client by using bytes script instead of str to avoid MagicMock encoder issue (hashlib.sha1 requires buffer-like object, not MagicMock) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>

Import should be added at the top of the file.

It would be better to validate that you can actually register the script using the RedisCluster client. With unit tests you won't be able to validate that we don't have a static code analyses errors, but what we can do is to validate that by providing the RedisCluster as valid input type - the client actually can be used to execute a register_script call.
