BUG: Copy attrs on pd.merge() #60357

Open timhoffm opened 6 days ago

timhoffm commented 6 days ago

This uses the same logic as pd.concat(): Copy attrs only if all input attrs are identical.

I've refactored the handling in finalize from special-casing based on th the method name (previously only "concat") to handling "other" parameters that have an input_objs attribute. This is a more scalable architecture compared to hard-coding method names in finalize.

Tests added for concat() and merge().

Closes #60351.
