GitAuto: [FEATURE] Handle missing labels from Dependabot PRs and automatically create them

[gitauto-ai]

Resolves #310

What is the feature

Automatically handle missing labels assigned by Dependabot in pull requests by detecting invalid label comments, creating the missing labels in the repository, and assigning them to the relevant issues or pull requests.

Why we need the feature

Dependabot occasionally assigns labels that do not exist within the repository, resulting in invalid label comments. This requires manual intervention to create and assign the missing labels, which can be time-consuming and disrupt the workflow. Automating this process ensures consistency, reduces manual effort, and maintains the integrity of label assignments in the repository.

How to implement and why

1. Webhook Handling:

   • Parse Webhook Payload: Set up a webhook listener to receive events from GitHub. Specifically, listen for comment events on pull requests and issues.
   • Detect Invalid Labels: When a comment is created by Dependabot, parse the comment body to identify any mentions of invalid labels using a regular expression.

2. Label Creation and Assignment:

   • Create Missing Labels: For each detected missing label, use the GitHub API to create the label in the repository with predefined attributes such as name, color, and description.
   • Assign Labels to Issues/PRs: After creating the labels, assign them to the corresponding issue or pull request using the GitHub API.

3. Integration with Existing Codebase:

   • Add LabelHandler Class: Incorporate the provided PHP LabelHandler class into the Src directory to manage label creation and assignment.
   • Configure Webhook Endpoint: Update the webhook handling logic in the repository to utilize the LabelHandler for processing incoming webhook payloads.

4. Testing:

   • Unit Tests: Write unit tests for the LabelHandler class to ensure it correctly parses comments, creates labels, and assigns them.
   • Integration Tests: Simulate webhook events to verify the end-to-end functionality of handling missing labels.

5. Documentation:

   • Update README: Document the new feature, including setup instructions for the webhook and usage examples.
   • Add Technical Notes: Provide detailed technical notes and resources in the repository's documentation to assist future developers in understanding and maintaining the feature.

This step-by-step implementation ensures that missing labels are automatically managed, enhancing the automation capabilities of Dependabot and maintaining repository consistency.

About backward compatibility

This feature introduces new functionality without altering existing workflows or configurations. It operates based on specific comments generated by Dependabot, ensuring that existing label management processes remain unaffected. Therefore, maintaining backward compatibility is straightforward, and the feature can be integrated without impacting current repository operations.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (Invoked using PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai full review to do a full review from scratch and review all the files again.
• @coderabbitai summary to regenerate the summary of the PR.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
• @coderabbitai help to get help.

Other keywords and placeholders

• Add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.
• Add @coderabbitai summary to generate the high-level summary at a specific location in the PR description.
• Add @coderabbitai anywhere in the PR title to generate the title automatically.

CodeRabbit Configuration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
