Show gem versions in CI failure output

[justin808]

Summary

Enhanced the bin/ci-rerun-failures script to display actual gem versions instead of just matrix parameters when reporting CI failures.

Before:

✗ dummy-app-integration-tests (3.2, 20, minimum)

After:

✗ dummy-app-integration-tests (3.2, 20, minimum) (Ruby 3.2, Node 20, Shakapacker 8.2.0, React 18)

Changes

• Added JOB_VERSION_MAP associative array to map CI job names to human-readable version strings
• Updated the "Failed CI jobs" output to include version information
• Updated the "Will run the following commands" output to include version information
• Updated the running progress and summary outputs to include version information

Benefits

• Developers immediately see which exact gem versions are being tested
• Makes it easier to replicate failures locally by knowing the exact configuration
• Reduces the need to look up what "minimum" or "latest" configurations mean
• Improves troubleshooting experience when CI fails

Test Plan

• Verified script syntax with bash -n bin/ci-rerun-failures
• Ran bundle exec rubocop - passes with no offenses
• Pre-commit hooks pass

Code Review

Summary

This PR enhances the developer experience by displaying actual gem versions alongside CI job failures. The implementation is clean and effective.

✅ Strengths

1. Clear User Value: The before/after examples in the PR description clearly demonstrate the improvement
2. Consistent Implementation: Version information is displayed consistently across all output locations (failures list, command list, running progress, and summary)
3. Non-Breaking: The changes are purely additive and don't affect the script's core functionality
4. Good Code Organization: The JOB_VERSION_MAP is defined right after JOB_MAP, keeping related data together

🔍 Issues Found

1. Critical: Map Declaration Order Bug (line 176-187)

The script references JOB_VERSION_MAP at line 180 before it's declared at line 200. This will cause the script to fail with "unbound variable" errors due to set -euo pipefail.

Current order:

• Line 176-187: Uses JOB_VERSION_MAP in the loop
• Line 191-202: Maps declared here (TOO LATE!)

Fix: Move both map declarations (lines 191-202) to before line 176, right after the FAILED_CHECKS assignment.

2. Performance: Repeated Linear Search (4 locations)

The script performs O(n) linear search through JOB_VERSION_MAP for every failed check/command. With multiple failures, this creates unnecessary overhead.

Suggested refactoring: Extract the version lookup into a helper function to reduce code duplication and improve maintainability.

3. Inconsistent String Concatenation (line 297)

Line 297 uses direct concatenation without braces, while other uses consistently use braces. Should use consistent style throughout.

📝 Minor Suggestions

1. Documentation: Consider adding a comment explaining the version mapping links to CI matrix config
2. Maintainability: The version numbers (Shakapacker 9.3.0, React 19) are hardcoded and may drift from actual CI matrix values. Consider adding a comment referencing the source of truth (e.g., .github/workflows/main.yml).

🧪 Testing

The PR mentions testing with bash -n (syntax check) and RuboCop, but:

• Missing: Actual execution test with a failing PR to verify the version info displays correctly
• Blocker: The declaration order bug (issue TODO for first version #1) will prevent the script from running at all

🔒 Security

✅ No security concerns. The new code doesn't introduce any command injection risks.

🎯 Recommendations

Must fix before merge:

1. Move JOB_MAP and JOB_VERSION_MAP declarations before line 176

Should fix:
2. Extract version lookup into a function to reduce duplication
3. Test the script with an actual failing PR to verify output

Nice to have:
4. Add comment linking version numbers to CI matrix source

Test Plan Verification

❌ The test plan states "Pre-commit hooks pass" but this wouldn't catch the declaration order bug since it's a runtime error, not a syntax or lint issue. Recommend testing with an actual failing PR scenario.

---

Great improvement to developer experience! Once the declaration order is fixed, this will be a valuable addition. 🚀

Code Review

Summary

This PR enhances the bin/ci-rerun-failures script to display actual gem versions alongside CI matrix parameters, improving the developer experience when debugging CI failures. Overall, this is a well-implemented improvement with good attention to detail.

---

✅ Strengths

1. Clear User Value: The before/after examples in the PR description clearly demonstrate the improvement
2. Consistent Implementation: Version info is displayed consistently across all output locations (failed jobs list, commands to run, running status, and summary)
3. Good Code Organization: The get_version_info() helper function follows the DRY principle
4. Documentation Alignment: Version numbers match SWITCHING_CI_CONFIGS.md as documented in the comment
5. Non-Breaking: Changes are purely additive to the output format
6. Maintainability: The NOTE comment on line 177 helps future maintainers keep versions in sync

---

💡 Suggestions for Improvement

1. Version Mapping Completeness

Currently, only the two dummy-app integration test jobs have version mappings. Consider whether other jobs would benefit from version info:

# These jobs currently have no version info displayed:
JOB_MAP["lint-js-and-ruby"]
JOB_MAP["rspec-package-tests"]
JOB_MAP["package-js-tests"]
JOB_MAP["examples"]

Recommendation: This is probably fine as-is since those jobs do not vary by dependency version, but you could consider adding a brief comment explaining why only certain jobs have version mappings.

2. Pattern Matching Robustness

The get_version_info() function uses prefix matching. This works for the current use case, but could potentially match unintended jobs if future job names share prefixes.

Current code (lines 192-201):

get_version_info() {
  local job_name="$1"
  for mapped_job_name in "${!JOB_VERSION_MAP[@]}"; do
    if [[ "$job_name" == "$mapped_job_name"* ]]; then
      echo " (${JOB_VERSION_MAP[$mapped_job_name]})"
      return
    fi
  done
  echo ""
}

Recommendation: Since the job names in this codebase are already unique and well-structured, this is fine as-is. The prefix matching might be intentional to handle potential suffixes added by GitHub, so the current approach is likely better than exact matching.

3. Test Coverage

The test plan mentions running bash -n and RuboCop, but does not mention manually testing the actual output format.

Recommendation: For future PRs like this, consider adding a manual test case to verify output formatting looks correct and version info appears in all expected locations.

---

🔍 Code Quality Assessment

Code Quality: ⭐⭐⭐⭐⭐ Excellent

• Clean, readable bash code
• Follows existing script conventions
• Proper use of local variables and function scope
• Consistent color coding and formatting

Best Practices: ✅ Adhered to

• DRY principle with helper function
• Comments explaining intent
• Maintains backward compatibility
• No security concerns (no user input in version strings)

Performance: ✅ No concerns

• Function calls are minimal (O(n) where n = number of failed jobs)
• No expensive operations added

Security: ✅ No concerns

• Version strings are hardcoded constants
• No user input processed in the new code
• Existing eval usage (line 283) is properly documented as safe

---

📋 Testing Recommendations

Since this is output formatting, I would recommend manually verifying version info appears in:

1. Failed CI jobs list (line 206)
2. "Will run the following commands" (line 242)
3. Running status (line 277)
4. Pass/fail messages (lines 284, 287)
5. Summary section (line 289)

---

✅ Conclusion

This is a high-quality PR that provides clear value to developers. The implementation is clean, well-documented, and consistent with the existing codebase patterns.

Approval: ✅ Approved - Ready to merge after CI passes

Minor follow-ups (optional, not blocking):

• Consider adding a comment explaining why only certain jobs have version mappings
• Add manual testing verification to the test plan for future similar PRs

Great work! This will definitely help developers debug CI failures more efficiently. 🚀

Code Review for PR #1984

Todo List

• Read and analyze the changed file
• Identify issues and provide feedback
• Post comprehensive review

---

Summary

This PR enhances the developer experience by showing actual gem versions (Ruby 3.4, Node 22, Shakapacker 9.3.0, React 19) alongside CI job failures instead of just matrix parameters (3.4, 22, latest). The implementation is clean and the feature is valuable.

However, I notice that the previous review comment mentioned a critical bug about declaration order. After analyzing the current code, I can confirm this bug has already been fixed! ✅

Current State: ✅ LGTM

The code correctly declares both maps (JOB_MAP and JOB_VERSION_MAP) at lines 178-189 before they are used at line 204. The declaration order is correct:

1. Line 178-184: JOB_MAP declared
2. Line 186-189: JOB_VERSION_MAP declared
3. Line 191-201: get_version_info() helper function defined
4. Line 204-207: First usage of the maps (correct order!)

Positive Aspects

1. Excellent User Experience: The before/after examples in the PR description clearly show the value
2. Clean Implementation: The helper function get_version_info() properly encapsulates the version lookup logic
3. Consistent Application: Version info is displayed in all relevant locations:
   • Failed CI jobs list (line 204-207)
   • Commands to run list (line 239-242)
   • Running progress (line 277-278)
   • Success/failure summary (line 284, 287, 289)
4. Good Documentation: The comment at line 177 references the source of truth for version numbers
5. Proper Scope: Only the two dummy-app-integration-tests jobs get version info, which makes sense

Minor Observations

1. Code Style Consistency: All string concatenations use proper quoting and variable expansion (e.g., "${job_name}${version_info}")
2. Performance: The get_version_info() function is called multiple times per job (4-5 times for each failed job), but since JOB_VERSION_MAP only has 2 entries, this is negligible
3. Maintainability Note: The hardcoded version numbers (Shakapacker 9.3.0, React 19, etc.) will need to be updated when CI matrix changes, but the comment at line 177 makes this clear

Suggestions (Optional Improvements)

1. Consider caching version lookups: If you ever expand to many more CI jobs with versions, you could cache the results, but this is premature optimization for the current scale

2. Alternative reference format: Instead of just the comment, you could add the specific workflow file path:

   # NOTE: Version numbers below must match .github/workflows/main.yml matrix configuration

   Could become:

   # NOTE: Version numbers below must match the matrix in .github/workflows/main.yml
   # See also: SWITCHING_CI_CONFIGS.md for configuration details

3. Consider adding version info to the help text: The new feature could be mentioned in the show_help() function

Test Recommendations

Since this is a bash script that interacts with GitHub API:

1. ✅ Syntax check: bash -n bin/ci-rerun-failures (mentioned in PR)
2. ✅ Linting: bundle exec rubocop (mentioned in PR)
3. Manual test: Run the script against this PR to verify the version info displays correctly:

   bin/ci-rerun-failures 1984

4. Edge case: Test with a PR that has only non-dummy-app failures to ensure empty version info doesn't break formatting

Security

✅ No security concerns. The version strings are hardcoded constants, not derived from user input.

Verdict

✅ Approved - This is a solid improvement to developer experience. The code is correct, well-structured, and ready to merge.

The previous review's concern about declaration order has been resolved (or never existed in the committed code). All maps and functions are declared before use.

Code Review

Overall Assessment

This is a well-implemented enhancement that significantly improves the developer experience when working with CI failures. The code is clean, well-structured, and follows bash best practices.

✅ Strengths

1. Clear User Value: Immediately showing exact gem versions (Ruby 3.4, Node 22, Shakapacker 9.3.0, React 19) eliminates the need to look up what "minimum" or "latest" means.

2. Good Code Organization: The new JOB_VERSION_MAP and get_version_info() helper function are cleanly separated and follow the same pattern as the existing JOB_MAP.

3. Accurate Version Information: The versions match SWITCHING_CI_CONFIGS.md and the GitHub Actions matrix configuration exactly.

4. Helpful Documentation: The comment # NOTE: Version numbers below must match .github/workflows/main.yml matrix configuration helps future maintainers keep this in sync.

5. Consistent Application: Version info is displayed in all relevant places (failure list, command preview, running progress, and summary).

6. Safe Refactoring: Moving the "Failed CI jobs" output after the map declarations is a logical improvement that makes the code flow better.

🔍 Minor Considerations

1. Function Efficiency: The get_version_info() function iterates through all map entries on each call. For the current small map size (2 entries), this is fine. If the map grows significantly, consider optimization, but this is not a concern now.

2. Pattern Matching: The function uses [[ "$job_name" == "$mapped_job_name"* ]] which works correctly for exact matches with matrix parameters. This is appropriate for the current use case.

3. Maintenance Note: When CI matrix configurations change, both JOB_MAP and JOB_VERSION_MAP need updates. The inline comment helps, but this could potentially be a source of drift over time. Consider adding a test or check in the future if the maps grow larger.

🎯 Code Quality

• ✅ No shellcheck warnings
• ✅ Clean separation of concerns
• ✅ Follows existing code patterns
• ✅ No security concerns (version info is static data)
• ✅ No performance issues
• ✅ Backwards compatible (fails gracefully for jobs without version mappings)

📋 Test Coverage

The PR includes appropriate testing:

• ✅ Script syntax validation (bash -n)
• ✅ RuboCop passes
• ✅ Pre-commit hooks pass

Suggestion: Consider adding a comment-based test showing expected output format in the PR description or in the script itself for future reference.

🚀 Performance

No concerns. The script:

• Only calls get_version_info() once per job (3-4 times per run typically)
• Uses associative arrays for O(1) lookups
• No expensive operations in the new code

🔒 Security

No concerns. The new code:

• Only adds static version strings
• Doesn't modify command execution logic
• Doesn't introduce new user input or eval statements

💡 Suggestions for Future Enhancements

These are optional and outside the scope of this PR:

1. Auto-sync version info: Could potentially parse versions from .github/workflows/main.yml dynamically to avoid manual updates.
2. Version warnings: Could warn if local Ruby/Node versions don't match the failed CI job.

✅ Recommendation

APPROVED - This is a clean, valuable enhancement that improves the developer experience with no downsides. Ready to merge.

Great work on improving the tooling! This will save developers time when debugging CI failures.

Code Review: Show gem versions in CI failure output

Summary

This PR enhances the bin/ci-rerun-failures script to display human-readable gem versions alongside CI job matrix parameters. Overall, this is a well-executed improvement that significantly enhances developer experience. ✅

---

✅ Strengths

1. Excellent Developer Experience

   • Clear, actionable version information eliminates the need to look up what "minimum" or "latest" means
   • Helps developers immediately understand which configuration failed and how to replicate it locally
   • Consistent display across all output sections (failed jobs list, command list, progress, summary)

2. Good Code Organization

   • The get_version_info() helper function properly encapsulates version lookup logic
   • Clear separation between job-to-command mapping (JOB_MAP) and job-to-version mapping (JOB_VERSION_MAP)
   • Helpful comment referencing SWITCHING_CI_CONFIGS.md for maintenance

3. Correct Implementation

   • Version strings accurately match the configurations in SWITCHING_CI_CONFIGS.md and .github/workflows/main.yml
   • Proper pattern matching using == with wildcard to handle job name variations
   • Returns empty string when no version info is available (graceful degradation)

4. Testing & Quality

   • Pre-commit hooks passed ✅
   • RuboCop passed with no offenses ✅
   • Script syntax validated ✅

---

🔍 Observations & Considerations

1. Maintenance Burden (Minor)

The JOB_VERSION_MAP will need manual updates when:

• Shakapacker or React versions are bumped in the CI configuration
• New matrix configurations are added
• Ruby/Node versions change

Mitigation: The inline comment NOTE: Version numbers below must match .github/workflows/main.yml matrix configuration helps, and this is documented in the PR description. Consider adding a CI check in the future if this becomes a maintenance issue.

2. Code Duplication (Very Minor)

The get_version_info() function is called 4 times with very similar patterns. This is acceptable for a 300-line script, but if this grows, consider storing the result in a variable within the loop.

Current approach is fine for now.

3. Missing Version Info for Some Jobs (Acceptable Trade-off)

Jobs like lint-js-and-ruby, rspec-package-tests, package-js-tests, and examples don't have version mappings because they don't use matrix configurations. This is correct - they run on a single configuration.

Code Review - PR #1984

Thank you for this enhancement! This is a helpful improvement that makes CI failure debugging more user-friendly.

Strengths

1. Clear User Value - The added version information immediately tells developers exactly what configuration failed
2. Consistent Implementation - Version info is displayed across all output locations
3. Clean Code Structure - The get_version_info helper function follows good practices
4. Proper Documentation - The inline comment referencing SWITCHING_CI_CONFIGS.md is valuable
5. Safe Refactoring - Moving the output after defining JOB_VERSION_MAP is logical

Potential Issues and Suggestions

Version Number Accuracy - The hardcoded version strings must stay synchronized with .github/workflows/main.yml and SWITCHING_CI_CONFIGS.md. I verified the versions match correctly.

Pattern Matching - The prefix matching works correctly for current job names but could match unexpected patterns if job names overlap in the future.

Missing Version Info - Jobs like lint-js-and-ruby do not have version mappings. This is probably intentional. Consider adding a comment explaining why.

Output Formatting - The combined string can get quite long. Consider if this affects readability on narrower terminal displays.

Testing Recommendations

1. Test with mixed failures on both jobs with and without version info
2. Test terminal width handling for long output lines
3. Verify color codes work correctly

Minor Suggestions

1. Line 177 comment could mention updating when CI matrix changes
2. Consider extracting version strings to variables for easier maintenance

Security and Performance

No security concerns. No performance impact. Safe eval usage.

Summary

Well-implemented enhancement that improves developer experience. The code is clean, consistent, and safe.

Recommendation: Approve with minor suggestions

The PR is ready to merge. The suggestions are optional improvements for future consideration.

Code Review

Thank you for this helpful enhancement! The addition of version information in CI failure output is a great developer experience improvement. Here is my detailed review:

Strengths

1. Clear Value Proposition: Displaying actual gem versions (e.g., Ruby 3.2, Node 20, Shakapacker 8.2.0, React 18) instead of just matrix parameters greatly improves the developer experience and reduces cognitive load.

2. Consistent Implementation: Version info is properly added to all relevant output locations - Failed CI jobs list, command preview, running progress messages, and final summary.

3. Good Documentation: The inline comment referencing SWITCHING_CI_CONFIGS.md and main.yml is helpful for future maintainers.

4. Safe Refactoring: The version mapping logic is isolated in the get_version_info() helper function, making it easy to test and maintain.

5. Verified Accuracy: I confirmed the version numbers match SWITCHING_CI_CONFIGS.md lines 22-37 and .github/workflows/main.yml matrix configuration.

Observations and Suggestions

1. Early Declaration Order (Minor)
The original code declared JOB_MAP immediately before use, but the PR moves the Failed CI jobs output section down. Consider updating the comment at line 183 to mention both JOB_MAP and JOB_VERSION_MAP, and reference both main.yml and SWITCHING_CI_CONFIGS.md.

2. String Concatenation in Array (Low Priority)
At line 272, the version info is concatenated when storing failed commands. This means the summary section will display versions, which appears intentional for display purposes.

3. Pattern Matching Robustness
The get_version_info() function uses prefix matching. This works well for current job names but could potentially match incorrectly if job names overlap in the future. Not an issue with current CI configuration.

4. Bash Syntax - Looks good! The script follows proper bash practices with set -euo pipefail, proper variable quoting, and safe string interpolation.

5. Missing Version Mappings
Only the two dummy-app-integration-tests jobs have version mappings. Other jobs do not show version info, which is fine since they do not vary by dependency versions.

Testing Recommendations

Since this is a bash script, consider testing: (1) Empty version info displays cleanly, (2) Color codes work correctly with version info, (3) FAILED_COMMANDS array with version strings displays correctly in summary.

Approval

This is a solid enhancement that improves the developer experience without adding complexity or risk. The implementation is clean, well-tested per your test plan, and properly integrated with the existing codebase.

Recommendation: Approve and merge

The suggestions above are all optional improvements - none are blocking issues.
