Summary of Suggestions and Changes

1. Files Identified for Modification:

   • src/triggers.py: This file contains functions to check specific conditions related to GitHub issues, such as checking for specific tags. It may need a new function to check for the 'catch_log' label.
   • src/agents.py: Handles agent creation and configuration for the GitHub bot. It might be involved in setting up the logic to parse logs and post comments on pull requests.
   • src/response_agent.py: Manages generating responses to GitHub issues. It could be used to implement the logic for parsing error logs and posting them as comments.
   • src/git_utils.py: Provides utility functions for interacting with the GitHub API. It might be used to fetch logs from GitHub actions and post comments on pull requests.

2. Plan to Address the Issue:

   • Detect the 'catch_log' Label: Modify triggers.py to include a function that checks for the 'catch_log' label on issues or pull requests.
   • Fetch and Parse Logs: Use git_utils.py to fetch logs from GitHub Actions and parse them for errors or tracebacks.
   • Post Comments on Pull Requests: Utilize response_agent.py to post the parsed error logs as comments on the relevant pull requests.

To address the feedback and provide an implementation for the fetch_and_parse_github_actions_log function, we need to add logic to fetch logs from GitHub Actions and parse them for errors or tracebacks. Here's how you can implement this function in src/git_utils.py:

Implementation of fetch_and_parse_github_actions_log

1. Fetch Logs from GitHub Actions: Use the GitHub API to access the logs of a specific workflow run associated with the issue or pull request.
2. Parse Logs for Errors: Implement logic to search for error messages or tracebacks within the logs.

Here's a possible implementation:

import requests

def fetch_and_parse_github_actions_log(issue: Issue) -> str:
    """
    Fetch and parse the GitHub Actions log for errors or tracebacks

    Args:
        issue: The GitHub issue to fetch logs for

    Returns:
        A string containing the parsed error or traceback
    """
    # Placeholder for fetching logs from GitHub Actions
    # Implement logic to fetch logs and parse for errors/tracebacks

    # Example: Fetch logs for a specific workflow run
    repo = issue.repository
    workflow_runs = repo.get_workflow_runs(event='pull_request', branch=issue.pull_request.head.ref)
    
    if workflow_runs.total_count == 0:
        return "No workflow runs found for this pull request."

    # Fetch the logs for the latest workflow run
    latest_run = workflow_runs[0]
    logs_url = latest_run.logs_url

    # Use GitHub API to download logs
    headers = {'Authorization': f'token {os.getenv("GITHUB_TOKEN")}'}
    response = requests.get(logs_url, headers=headers)

    if response.status_code != 200:
        return f"Failed to fetch logs: {response.status_code} {response.reason}"

    logs = response.text

    # Parse logs for errors or tracebacks
    error_lines = []
    for line in logs.splitlines():
        if "error" in line.lower() or "traceback" in line.lower():
            error_lines.append(line)

    if not error_lines:
        return "No errors or tracebacks found in logs."

    return "\n".join(error_lines)

Suggested Changes

• File: src/git_utils.py
• Line: Add the above function after line 115

Explanation

• Fetching Logs: The function uses the GitHub API to fetch logs for the latest workflow run associated with the pull request. It assumes the issue is linked to a pull request.
• Parsing Logs: It searches for lines containing "error" or "traceback" to identify potential issues in the logs.

This implementation provides a basic structure for fetching and parsing logs. You may need to adjust the logic to fit the specific requirements and structure of your GitHub Actions workflows.

implement a parse_GitHub_action_logs function that is used by the fetch_and_parse function

[abuzarmahmood]

To address the feedback and improve the original response, we can refactor the fetch_and_parse_github_actions_log function to utilize a separate parse_github_action_logs function. This will enhance modularity and make the code easier to maintain and test. Here's how you can implement these changes in src/git_utils.py:

Implementation of parse_github_action_logs

First, let's define the parse_github_action_logs function, which will handle the parsing of logs for errors or tracebacks:

def parse_github_action_logs(logs: str) -> str:
    """
    Parse GitHub Actions logs for errors or tracebacks.

    Args:
        logs: The logs from a GitHub Actions workflow run.

    Returns:
        A string containing the parsed error or traceback messages.
    """
    error_lines = []
    for line in logs.splitlines():
        if "error" in line.lower() or "traceback" in line.lower():
            error_lines.append(line)

    if not error_lines:
        return "No errors or tracebacks found in logs."

    return "\n".join(error_lines)

Updated fetch_and_parse_github_actions_log Function

Now, update the fetch_and_parse_github_actions_log function to use the new parse_github_action_logs function:

import requests
import os

def fetch_and_parse_github_actions_log(issue: Issue) -> str:
    """
    Fetch and parse the GitHub Actions log for errors or tracebacks.

    Args:
        issue: The GitHub issue to fetch logs for.

    Returns:
        A string containing the parsed error or traceback.
    """
    repo = issue.repository
    workflow_runs = repo.get_workflow_runs(event='pull_request', branch=issue.pull_request.head.ref)
    
    if workflow_runs.total_count == 0:
        return "No workflow runs found for this pull request."

    latest_run = workflow_runs[0]
    logs_url = latest_run.logs_url

    headers = {'Authorization': f'token {os.getenv("GITHUB_TOKEN")}'}
    response = requests.get(logs_url, headers=headers)

    if response.status_code != 200:
        return f"Failed to fetch logs: {response.status_code} {response.reason}"

    logs = response.text
    return parse_github_action_logs(logs)

Suggested Changes

• File: src/git_utils.py
• Lines:
  • Add the parse_github_action_logs function after line 115.
  • Update the fetch_and_parse_github_actions_log function to use parse_github_action_logs.

Explanation

• Modularity: By separating the parsing logic into its own function, the code becomes more modular and easier to test independently.
• Reusability: The parse_github_action_logs function can be reused in other parts of the codebase if needed.

This refactoring maintains the original functionality while addressing the feedback to implement a separate parsing function.
