Rich error output during baseline establishment (CF-646)

[aseembits93]

User description

It could help the user with cancelling the current run if certain modules are not found during a run.

this PR will only show the first import error as the code would stop executing the moment the first import fails. capturing all import errors will require a different way of test instrumentation.

Description

• Improve error reporting on missing modules

• Detect ModuleNotFoundError in test outputs

• Show errors using Rich panel

• Add import for regex parsing

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 Missing Import The code uses Panel and console without importing them, which will cause a NameError at runtime. Ensure you import Panel (e.g., from rich.panel) and initialize or import a console instance before using them. if 'ModuleNotFoundError' in run_result.stdout: from rich.text import Text match = re.search(r'^.*ModuleNotFoundError.*$', run_result.stdout, re.MULTILINE).group() panel = Panel( Text.from_markup(f"⚠️ {match} ", style="bold red"), expand=False, ) console.print(panel) if testing_type in {TestingMode.BEHAVIOR, TestingMode.PERFORMANCE}: Unsafe Regex Handling Calling .group() on the result of re.search without checking if a match was found can lead to an AttributeError. Add a null check on the match object before using group(). match = re.search(r'^.*ModuleNotFoundError.*$', run_result.stdout, re.MULTILINE).group()

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Check stderr for errors Include run_result.stderr in the error check so that module not found messages emitted to stderr are also captured. codeflash/optimization/function_optimizer.py [1197] -if 'ModuleNotFoundError' in run_result.stdout: +combined_output = run_result.stdout + run_result.stderr +if 'ModuleNotFoundError' in combined_output: Suggestion importance[1-10]: 6 __ Why: Including stderr in the search for ModuleNotFoundError captures errors emitted there as well, improving robustness of the check.	Low
Possible issue	Guard regex group call Add a check that the regex search succeeded before calling .group() to prevent an AttributeError if no match is found. codeflash/optimization/function_optimizer.py [1199] -match = re.search(r'^.*ModuleNotFoundError.*$', run_result.stdout, re.MULTILINE).group() +match_obj = re.search(r'^.*ModuleNotFoundError.*$', run_result.stdout, re.MULTILINE) +if match_obj: + match = match_obj.group() +else: + match = "ModuleNotFoundError occurred" Suggestion importance[1-10]: 4 __ Why: Guarding the .group() call prevents an AttributeError if the regex unexpectedly finds no match, although the preceding substring check makes failure unlikely.	Low

place the regex in a common place and then import it within the test, if the regex every changes then the test will automatically pick the change
