Walkthrough

The pull request introduces modifications to two workflow files, .github/workflows/build.yml and .github/workflows/drive.yml, to enhance the handling of pull request events. In build.yml, new steps are added to save and upload the pull request ID conditionally. In drive.yml, several steps are updated to execute only when a pull request event occurs, refining the control flow based on event types.

Changes

Files Change Summary
.github/workflows/build.yml Added steps to save and upload the pull request ID, conditional on pull request events.
.github/workflows/drive.yml Updated multiple steps to execute conditionally based on pull request events.

🐇 In the meadow, hops a little hare,
With PR IDs floating in the air.
Steps to save and upload with glee,
In workflows, they dance, wild and free!
Pull requests now shine, oh what a sight,
With every merge, they take flight! 🌼

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.

.github/workflows/build.yml (1)

Line range hint 87-99: Well-designed workflow communication pattern.

The implementation of PR ID passing between workflows through artifacts is a robust solution for cross-workflow communication. This pattern ensures that the drive workflow can correctly identify and handle PR-specific actions, addressing the core issue where the drive action was failing during merges.

A few architectural benefits of this approach:

  1. Clear separation of concerns between build and drive workflows
  2. Reliable PR context sharing using GitHub's artifact system
  3. Proper cleanup with the 1-day retention period

.github/workflows/drive.yml (4)

Line range hint 24-43: LGTM! Consider enhancing the error message.

The conditional check if: github.event_name == 'pull_request' correctly fixes the workflow failure during merges by ensuring PR ID artifact is only downloaded during pull request events.

Consider making the error message more descriptive:

-              core.setFailed('No pr_id artifact found from the build workflow');
+              core.setFailed('No pr_id artifact found from the build workflow. This is expected for non-PR events.');

Line range hint 55-63: Fix incorrect variable name in error message.

The error message references a non-existent variable prIdContent instead of issue_number.

Apply this fix:

             let issue_number = fs.readFileSync('./pr_id');
             if (!issue_number || isNaN(Number(issue_number))) {
-              core.setFailed(`Invalid PR ID: ${prIdContent}`);
+              core.setFailed(`Invalid PR ID: ${issue_number}`);
               return;
             }

Line range hint 77-102: Add error handling for JSON operations.

While the conditional check fixes the merge issue, the script should handle potential JSON-related errors gracefully.

Consider adding error handling:

             const fs = require('fs');
-            // read the simulation results
-            const results = fs.readFileSync('./simulation_results.json', 'utf8');
-            let resultsJson = JSON.parse(results);
+            try {
+              // read the simulation results
+              const results = fs.readFileSync('./simulation_results.json', 'utf8');
+              let resultsJson = JSON.parse(results);
+              
+              // validate expected structure
+              if (!resultsJson.values || !resultsJson.labels || 
+                  !Array.isArray(resultsJson.values) || 
+                  !Array.isArray(resultsJson.labels)) {
+                throw new Error('Invalid simulation results structure');
+              }
+              
+              // rest of the code...
+            } catch (error) {
+              core.setFailed(`Failed to process simulation results: ${error.message}`);
+              return;
+            }

Line range hint 1-20: Consider adding workflow documentation.

The workflow successfully handles both PR and non-PR events, but could benefit from documentation explaining:

  • Expected artifact structure
  • Different execution paths (PR vs non-PR)
  • Self-hosted runner requirements

Add a comment block at the top of the file:

 name: Evaluate agent
+# This workflow evaluates the agent by running simulations and handles results differently for PR and non-PR events:
+# - For PRs: Downloads PR ID, runs simulation, and posts results as PR comments
+# - For other events (e.g., merges): Only runs simulation
+#
+# Required artifacts from build workflow:
+# - pr_id: Text file containing PR number (only for PR events)
+#
+# Required runner capabilities:
+# - Docker with compose

Line range hint 95-99: Verify artifact handling in drive workflow.

The PR ID artifact upload looks good. Let's verify that the corresponding download step in drive.yml correctly handles this artifact.

✅ Verification successful

PR ID artifact handling is correctly implemented in drive workflow

The drive workflow correctly downloads and handles the PR ID artifact using a more robust approach with actions/github-script@v6. The workflow:

  • Downloads the artifact using GitHub API
  • Unzips the artifact
  • Validates the PR ID content
  • Uses the PR ID to post simulation results as comments
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify that drive.yml has corresponding download steps for the PR ID artifact

# Test: Check for artifact download step in drive.yml
# Expect: Should find matching download step with same artifact name
rg -A 5 'actions/download-artifact@v[0-9]' .github/workflows/drive.yml
rg 'name: pr_id' .github/workflows/drive.yml

Length of output: 119


Script:

#!/bin/bash
# Let's first check if drive.yml exists and see its content
fd -e yml -e yaml "drive" .github/workflows/

# If drive.yml doesn't exist, let's check all workflow files for artifact download
fd -e yml -e yaml . .github/workflows/ --exec cat {} \;

.github/workflows/drive.yml (1)

Line range hint 1-102: Verify workflow structure and dependencies.

The changes correctly fix the drive action failure during merges by making PR-specific steps conditional. Let's verify the complete workflow structure and dependencies.

✅ Verification successful

Workflow changes are properly structured and dependencies are verified

The verification confirms:

  • The workflow is correctly triggered by "Build and push image" workflow
  • PR ID artifact is properly created in the build workflow
  • All PR-specific steps are consistently conditioned with if: github.event_name == 'pull_request'
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify workflow structure and dependencies

# Test 1: Verify this workflow is properly triggered
echo "Checking workflow triggers..."
rg -l "workflow_run:.*Build and push image" .github/workflows/

# Test 2: Check for corresponding build workflow that provides PR ID
echo "Checking for PR ID artifact creation in build workflow..."
rg "pr_id" .github/workflows/build.yml

# Test 3: Verify all PR-specific steps are properly conditioned

⚠️ Potential issue

Quote the PR_ID variable in the shell command.

The shell command should quote the PR_ID variable to prevent word splitting and ensure proper handling of special characters.

Apply this diff to fix the shell command:

        run: |
          mkdir -p ./pr
-          echo $PR_ID > ./pr/pr_id
+          echo "$PR_ID" > ./pr/pr_id
