Implementing Fallback Mechanisms for YAML Parsing

[mrT23]

PR Type:

Enhancement

---

PR Description:

This PR introduces two fallback mechanisms to handle cases where the initial YAML parsing fails:

• The first fallback attempts to convert 'relevant line: ...' to 'relevant line: |-\n ...' and then parse the YAML.
• If the first fallback fails, the second fallback attempts to parse the YAML after removing the last lines one by one until successful parsing is achieved.

PR Main Files Walkthrough:

files:

• pr_agent/algo/utils.py: Added two fallback mechanisms in the 'try_fix_yaml' function to handle cases where the initial YAML parsing fails. The first fallback modifies the 'relevant line' format, and the second fallback removes the last lines until the YAML can be parsed successfully.

PR Feedback

• 💡 General suggestions: The fallback mechanisms introduced in this PR are a good way to handle parsing errors. However, it would be beneficial to add tests to ensure these fallbacks work as expected.

• 🤖 Code feedback:

  • relevant file: pr_agent/algo/utils.py
    suggestion: Consider adding a limit to the number of lines removed in the second fallback. This will prevent the function from entering an infinite loop if the YAML is not parsable. [important]
    relevant line: for i in range(1, len(review_text_lines)):

  • relevant file: pr_agent/algo/utils.py
    suggestion: It would be beneficial to log the exception message when the parsing fails. This will help in debugging and understanding why the parsing failed. [medium]
