Analysis of Pull Requests for Codium-ai/cover-agent

Open Pull Requests

PR #33: new prompts and flow design

  • State: Open
  • Created: 0 days ago
  • Type: Enhancement, Tests, Configuration changes

  • Description:

    • Refactored AICaller to handle dict prompts.
    • Updated PromptBuilder to use Jinja2 templates.
    • Added language support and line numbering.
    • Updated UnitTestGenerator for new PromptBuilder.
    • Added YAML parsing utilities.
    • Integrated Dynaconf settings loader.
    • Comprehensive language extension mappings.
    • Added tests for new functionalities.

  • Notable Issues:

    • CI Failure: The build failed due to a ModuleNotFoundError for the settings module. This needs immediate attention as it blocks the merging process.
    • Possible Bug: Potential KeyError in AICaller.py if 'system' key is missing in the input dictionary.
    • Refactoring Concern: The significant refactor in PromptBuilder could introduce issues if not all scenarios are covered by tests.
    • Performance Issue: Iteration over extensions in get_code_language method could be optimized.

PR #27: feat: added API url configuration for Ollama and Hugging Face models

  • State: Open
  • Created: 0 days ago
  • Type: Enhancement, Documentation

  • Description:

    • Added api_base parameter to AICaller.
    • Updated CLI to accept custom API URLs.
    • Documented usage of custom API URLs.

  • Notable Issues:

    • Possible Bug: Conditional logic in call_model might lead to unintended behavior if other model names contain substrings "ollama" or "huggingface".
    • Code Suggestions: Validate the api_base argument to ensure it is a properly formatted URL.
