Issue

The "Add Files Changed Label" workflow was failing with permission errors when trying to add labels to PRs from external repositories (forks). This would result in the following error:

Resource not accessible by integration

Solution

Modified the workflow to detect when a PR is coming from an external repository (fork) and gracefully skip the label operations in that case:

  1. Added environment variables to track source repositories:

    • PR_HEAD_REPO: The repository where the PR changes are coming from
    • BASE_REPO: The repository where the workflow is running

  2. Added a conditional check at the beginning of the workflow script:

    # Check if PR is from a fork (external repository)
if [[ "$PR_HEAD_REPO" != "$BASE_REPO" ]]; then
  echo "This PR is from an external repository: $PR_HEAD_REPO"
  echo "Skipping label operations for external repository PR to avoid permission issues."
  exit 0
fi

  3. This allows the workflow to:

    • Proceed normally for PRs from the same repository
    • Skip label operations for PRs from forks with a clear log message
    • Exit gracefully with code 0 to prevent workflow failures

Benefits

  • No more permission errors in the workflow logs
  • Clear messaging about why labels aren't applied for external PRs
  • Workflow completes successfully in all cases

Fixes #4313.

🪧 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.
    • Explain this complex logic.
    • 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 explain this code block.
    • @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 explain its main purpose.
    • @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.

Support

Need help? Join our Discord community for assistance with any issues or questions.

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 generate sequence diagram to generate a sequence diagram of the changes in this 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
