Gemini outputs an HTML comment within Python block

This is an example of a test case file generated by Gemini. You can see that it's including an HTML-style comment within the Python fences. The result is invalid Python code.

Within backticks:

<!-- file: /home/runner/work/navie-benchmark/navie-benchmark/solve/django__django-14559/source/tests/queries/test_bulk_update_return_value.py -->
from django.test import TestCase

from .models import Note

class BulkUpdateReturnValueTests(TestCase):
    def test_return_value(self):
        notes = [Note.objects.create(note='initial') for _ in range(10)]
        num_updated = Note.objects.bulk_update(notes, ['note'], batch_size=100)

        self.assertIsNone(num_updated)

When generating test case code, strip out any HTML comments from the beginning of the file, after extracting code from fences.

Title: Remove HTML Comments Before Generating Python Test Case Files

Problem:

The problem arises from an HTML-style comment being included within the Python code fences generated by Gemini. This inclusion results in invalid Python code because Python interpreters cannot process HTML-style comments. Consequently, the generated test case files become invalid and cannot be executed without errors.

Analysis:

The issue is caused by the presence of an HTML comment block that is supposed to denote the file path (metadata), which is being inadvertently included within Python code fences. This comment is not valid in Python and causes syntax errors when the code is executed or evaluated by any Python processing tool.

A viable solution is to ensure that any HTML comments are stripped out at the time of generating or processing the code block contents before they are integrated into the test case file output. By doing so, only legitimate Python code will form the body of the test case file.

Proposed Changes:

Code Processing Function:
- Modify the component that processes code file generation to include a step that identifies and removes HTML comment lines from the code contents. This should occur before the code is saved into a Python test file.

File Writing Logic:

# Update the logic responsible for extracting code within backticks and ensure:
# - Any HTML comment at the beginning of the code block is identified.
# - Remove these comments before the code is written to a `.py` file.
# The specific operation should iterate over each extracted line 
# and exclude lines that match the HTML comment pattern.

Integration Points:
- Apply HTML comment stripping logic to any point in the codebase that handles writing or generating Python files from extracted code blocks. This should ensure consistent handling of all generated code pieces.
Validation and Testing:
- Create unit tests ensuring that any HTML comments from code blocks are adequately stripped out.
- Design test cases to check that files post-processing do not contain any HTML comment artifacts.

By implementing these adjustments, the Gemini system will produce cleaner and executably valid test case files absent of improper HTML comments.
