Enhance Error Handling for GitHub API Rate Limits and Network Failures #65

While the code bases provided show a well-structured, modular design for automating GitHub issue handling and interacting with GitHub via Python scripts, integrating with language models for code and documentation generation, there's a critical issue that stands out related to error handling and robustness in services/github/__init__.py.

Issue Summary: There is lacking comprehensive error handling around GitHub API rate limits and potential API failures. When the script makes requests to GitHub, such as cloning repositories, creating issues, pulling repository changes, etc., it doesn't explicitly handle cases where GitHub might rate limit the API requests or when temporary network issues occur, causing API requests to fail. Such scenarios could lead to script crashes or unexpected behavior without retries or proper error messages communicated back to the user.

Potential Solutions:

  1. Implement retry mechanisms with exponential backoff for GitHub operations that are prone to fail due to API rate limits or network issues.
  2. Surround network-related operations with more granular try-except blocks to catch and handle specific GitHub API exceptions. This includes handling exceptions defined in services/github/exceptions.py more explicitly throughout the GitHub interactions.
  3. Introduce rate limit checks before making API calls and wait or notify the user if the script is about to hit rate limits based on GitHub's API rate limit documentation.
  4. Provide detailed error messages back to the user, suggesting steps for resolution or automatically adjusting the behavior of the script (e.g., slowing down requests, switching to a different GitHub token with a fresh rate limit, etc.).

This approach not only enhances the robustness of the script against transient failures and API limitations but also improves the user experience by avoiding cryptic errors and informing the user about the nature of issues and potential workarounds.
