Walkthrough

The update modifies the internal logic of the FunctionName utility to safely handle nil and typed nil inputs, preventing panics by adding multiple nil checks. Tests are expanded to verify behavior with various nil scenarios and to confirm type name formatting for user-defined types. No public interfaces or function signatures are changed.

Changes

File(s) Change Summary
common.go Enhanced FunctionName with nil and typed nil checks to avoid panics and ensure safe function name retrieval.
common_test.go Added test cases for FunctionName covering nil, typed nil, typed nil functions, and type name formatting for structs and pointers.

Poem

In the warren of code, where bugs may hide,
A nil check was added, so errors subside.
Tests now explore each burrow and nook,
Ensuring no panic, no matter the look.
🐇 Robustness increased, with a hop and a cheer,
Our code is now safer—let’s all give a thump here!

Hello @gaby, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the robustness and reliability of the FunctionName utility by addressing potential panics caused by nil inputs and significantly expanding its test coverage. The changes aim to make the function more predictable and stable when dealing with diverse input types, including various forms of nil values.

Highlights

  • FunctionName Robustness: The FunctionName utility function has been updated to prevent panics when nil is passed as an argument, specifically handling the interface{}(nil) case by returning an empty string.
  • Expanded Test Coverage: Comprehensive new test cases have been added for FunctionName, covering various scenarios including nil interfaces, typed nil functions, typed nil pointers, and different struct types, ensuring expected behavior across edge cases.
