[Lsp] return diff functions grouped by file

[mohammedahmed18]

needed for https://github.com/codeflash-ai/codeflash-internal/pull/1761
The lsp client needs to know what is the file for each function to be able to send the optimization request with --file

---

Description

• Group functions by file in current diff

• Change return format to file-to-functions dict

• Update return type annotation

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Type Annotation The return type annotation is too generic and doesn’t explicitly define the expected keys and value types. Consider defining and using a TypedDict to represent the structured response with keys "functions" and "status" for improved clarity and type safety. ) -> dict[str, str | dict[str, list[str]]]: functions = get_functions_within_git_diff(uncommitted_changes=True) Missing Tests There are no tests added or updated to verify the new grouped-by-file diff functionality. It would be beneficial to add unit tests covering typical and edge cases for get_functions_in_current_git_diff. file_to_qualified_names: dict[str, list[str]] = { str(path): [f.qualified_name for f in funcs] for path, funcs in file_to_funcs_to_optimize.items() } return {"functions": file_to_qualified_names, "status": "success"}

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Sort qualified names lists Sort the lists of function names so that the output is deterministic and easier to test. This ensures consistent ordering across runs. codeflash/lsp/beta.py [58-60] file_to_qualified_names: dict[str, list[str]] = { - str(path): [f.qualified_name for f in funcs] for path, funcs in file_to_funcs_to_optimize.items() + str(path): sorted(f.qualified_name for f in funcs) for path, funcs in file_to_funcs_to_optimize.items() } Suggestion importance[1-10]: 7 __ Why: Sorting the list from [f.qualified_name for f in funcs] yields deterministic output for functions results, aiding reproducible tests and debugging.	Medium
	Normalize file path format Convert file path keys to POSIX format using path.as_posix() to ensure consistent separators across platforms. This avoids OS-specific path issues when serializing to JSON. codeflash/lsp/beta.py [58-60] file_to_qualified_names: dict[str, list[str]] = { - str(path): [f.qualified_name for f in funcs] for path, funcs in file_to_funcs_to_optimize.items() + path.as_posix(): [f.qualified_name for f in funcs] for path, funcs in file_to_funcs_to_optimize.items() } Suggestion importance[1-10]: 6 __ Why: Using path.as_posix() ensures consistent path separators across platforms, improving JSON serialization portability without altering functionality.
