@tagliala tagliala commented Jan 8, 2025

Generator specs experience random failures likely due to numerous
network requests to the node registry.

To mitigate this, continue-on-error: true is set, allowing the current
combination to fail without halting other matrix combinations.

Summary by CodeRabbit

  • Chores
    • Updated GitHub Actions workflow configuration to improve test job resilience.
    • Added option to continue workflow execution even if a test matrix combination fails.

Walkthrough

The pull request introduces a configuration change in the GitHub Actions workflow file for the generator specifications. By adding continue-on-error: true to the test job, the workflow is now designed to continue executing other matrix combinations even if a specific test combination fails. This modification addresses potential random failures in generator specs, likely caused by network request complexities to the node registry, ensuring the CI process remains robust and uninterrupted.

Changes

File Change Summary
.github/workflows/generator.yml Added continue-on-error: true to the test job to allow workflow continuation despite individual test failures

Poem

🐰 In the realm of CI's dance,
Where tests hop and workflows prance,
A rabbit's trick, so wise and neat,
Let errors fail, but don't retreat!
Continuing on with graceful might,
The generator specs 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.

22-22: Consider monitoring failed combinations.

The continue-on-error: true setting is appropriate for handling transient failures. However, to maintain visibility into these failures:

  1. Consider adding a post-job step to aggregate and report failed combinations
  2. Set up monitoring to track the frequency of failures to identify patterns

Here's a verification script to analyze the current failure patterns:

#!/bin/bash
# Description: Check recent workflow runs to understand failure patterns

# Get the last 20 workflow runs for the generator specs
gh run list --workflow=generator.yml --limit 20 --json conclusion,createdAt,url | \
  jq 'map(select(.conclusion != "success")) | map({conclusion, created_at: .createdAt, url})'

18-21: Well-documented explanation for the change.

The comments clearly explain the problem (random failures due to network requests) and the solution (allowing individual matrix combinations to fail without affecting others).

Generator specs experience random failures likely due to numerous
network requests to the node registry.

To mitigate this, `continue-on-error: true` is set, allowing the current
combination to fail without halting other matrix combinations.

I don't quite see this being a particularly good idea. Most of the errors we've been seeing have been widespread so failing fast worked quite well.

Current issues are widespread and not just affecting us actions/runner-images#3737 and we've not seen anything to that extent before.

There might be cases down the line where some old Ruby/Rails started falling and it could be more obvious with other jobs succeeding that this is isolated, but that's not enough benefit IMO to warrant this change.

Yes, in this particular execution a lot of failures are happening, in my tests in the fork just 2 or 3 over 24 jobs failed
