Description

Development notes

First attempt, I haven't ran the test suite locally yet. But pip install -e .[test] worked first time on Apple Silicon.

rings a bell but I don't have time to look at this right now, will do so later.

This is the flaky test that occasionally fails. I think @lrcouto was seeing this as well on her PR for adding the _EPHEMERAL attribute.

This test is different than the one I've seen. There was one that was caused by a requirement version, which Nok fixed, and another that happened in the tests for the starters. This one is new to me.

@astrojuanlu Maybe you can add some context on the challenges you're seeing in #3287 and then we can properly plan it for a sprint?

Fixed the test to check for the intended behaviour. However, it fails, and manual testing shows that this is due to the implementation of the OmegaConfigLoader. I would suggest correcting this should be split out into a separate issue to be addressed.

I don't agree with this being addressed in a separate issue, adding the 3.12 support is what's making this fail and thus it should be fixed in this PR.

It's not the move to include 3.12 that's causing this test to fail, but rather it was never truly passing, the previous method call used for the assert was mistyped, leading to a trivial pass. To resolve this requires digging further into the implementation of the OmegaConfigLoader, as it is not behaving as expected, and perhaps never was. See xref.

kedro/config/abstract_config.py

+    # From Python 3.12 __getitem__ isn't called in UserDict.get()
+    # Use the version from 3.11 and prior
+    def get(self, key: str, default: Any = None) -> Any:
+        "D.get(k[,d]) -> D[k] if k in D, else d.  d defaults to None."
+        try:
+            return self[key]
+        except KeyError:
+            return default
+


Why is this needed?

See this issue, the UserDict's get implementation in 3.12 doesn't work for the config loader anymore, so the method is overwritten to use the get function from the previous python versions

~~I will make the comment in the file more clear~~ Done!

Should this be on OmegaConfigLoader or the abstract method? I am slightly confused why get method is needed for OmegaConf.

Should this be on OmegaConfigLoader or the abstract method?

I went for the AbstractConfigLoader to catch any cases where users have defined their own Config Loaders (for whatever reason) that inherit from the AbstractConfigLoader.

I am slightly confused why get method is needed for OmegaConf.

Whilst we don't promote using get over the dict syntax, we have made it available - and it features in our API docs - allowing users to do something like:

conf_loader = OmegaConfigLoader(<...>) if not conf_loader.get("parameters"): parameters = MY_LOCAL_PARAMS

Ultimately, removing get() is a breaking change, which would block adding 3.12 support until the next major release.
