Change Summary

📄 _field_name_for_signature() in pydantic/_internal/_signature.py

📈 Performance improved by 37% (0.37x faster)

⏱️ Runtime went down from 42.3 microseconds to 30.9 microseconds

Explanation and details

To optimize the runtime and memory usage of the given Python function, we can inline the _alias_if_valid function to avoid the overhead of additional function calls and reduce the redundancy. Here's the optimized version of the code.

Explanation.

1. Inlining _alias_if_valid Function: By inlining the code of _alias_if_valid directly into _field_name_for_signature, we eliminate the overhead of multiple function calls and simplify the logic.
2. Conditional Checks: Add checks directly within the return statement to reduce unnecessary temporary variables.

These changes should help in reducing the runtime and memory overhead of the function while maintaining the same functionality and returned values.

This optimization was automatically discovered with codeflash.ai

Looks good, I'd like to use this pattern of removing unnecessary inlining at other points in this file as well.
