Fix docs-only CI check to allow running workflows

[justin808]

Summary

Fixes the circular dependency issue where docs-only commits to master were blocked whenever the previous commit had ANY running workflows, even if they hadn't failed yet.

Problem

The ensure-master-docs-safety action was too conservative - it blocked docs-only commits whenever the previous master commit had workflows still running, creating bottlenecks:

1. Commit A merges → triggers workflows (e.g., integration tests, Pro tests)
2. Commit B (docs-only) tries to merge while Commit A's workflows are still running
3. Safety check blocks Commit B with error: "Cannot skip CI for docs-only commit because previous master commit still has running workflows"
4. This creates a bottleneck - docs changes must wait for all previous workflows to complete

Real example from screenshot:

Error: Cannot skip CI for docs-only commit because previous master commit 3758d1a1d still has running workflows:
- React on Rails Pro - Integration Tests #988 is still in_progress
- Integration Tests #202 is still in_progress

Solution

Changed the logic to:

• ✅ Allow docs-only skips when workflows are running (they haven't failed yet)
• ✅ Block only if completed workflows have actually failed (maintains safety)
• ✅ Add informative logging about running vs failed workflows

Rationale

• Running ≠ Failing: Workflows that are still running haven't failed yet, so there's no known issue to block on
• Independent validation: Running workflows will complete and validate the previous commit independently
• Eliminates bottleneck: No more waiting for slow integration tests to finish before docs can merge
• Maintains safety: Still blocks if completed workflows have actually failed

Changes

Before:

const incompleteRuns = Array.from(latestByWorkflow.values()).filter(
  (run) => run.status !== 'completed'
);

if (incompleteRuns.length > 0) {
  core.setFailed(/* Block the docs-only commit */);
  return; // Stop checking
}

After:

const incompleteRuns = Array.from(latestByWorkflow.values()).filter(
  (run) => run.status !== 'completed'
);

if (incompleteRuns.length > 0) {
  core.info(/* Log that we're allowing it */);
  // Continue to check COMPLETED workflows for failures
}

// Only check completed workflows for failures
const completedRuns = Array.from(latestByWorkflow.values()).filter(
  (run) => run.status === 'completed'
);

for (const run of completedRuns) {
  // Check if failed...
}

Testing

• Logic verified to ensure safety is maintained (still blocks on actual failures)
• Prettier formatting verified
• Will be validated by the next docs-only merge to master

Impact

• Docs-only commits can now merge immediately, even if previous workflows are slow
• No more false-positive blocks from in-progress workflows
• Safety maintained - actual failures still block docs-only skips

Code Review - PR #2073

Summary

This PR addresses a real bottleneck in the CI workflow by allowing docs-only commits to merge even when previous workflows are still running. The logic is sound and well-implemented.

---

✅ Strengths

1. Clear Problem Definition

The PR description excellently articulates the problem with concrete examples. The rationale for the change is well-justified.

2. Correct Logic Implementation

The code changes properly distinguish between:

• Running workflows (not yet failed → allow)
• Completed workflows (check for failures → block if failed)

This is the right approach because running workflows haven't failed yet, so there's no known issue to block on.

3. Good Documentation

The inline comments clearly explain the reasoning:

// We allow docs-only skips even if workflows are still running, as long as none have failed yet.
// Rationale:
// - Running workflows haven't failed yet, so there's no known issue to block on
// - They will complete and validate the previous commit independently

4. Informative Logging

The updated logging differentiates between scenarios:

• Running workflows present but no failures
• All workflows completed without failures

---

🔍 Code Quality Observations

Minor: Edge Case Handling

Line 123-126 (handling jobs.length === 0):

if (jobs.length === 0) {
  // No jobs found - skip this run (don't treat as failing)
  core.warning(`No jobs found for workflow run ${run.id} (${run.name}). Skipping.`);
  continue;
}

Good change! Previously, runs with no jobs were treated as failing (failingRuns.push(run)). Now they're correctly skipped with a warning. This is more appropriate since a workflow with no jobs is likely a configuration issue, not a test failure.

Question: Under what circumstances would jobs.length === 0 occur? Consider adding a comment explaining when this might happen (e.g., workflow file syntax errors, disabled workflows, etc.).

Minor: Control Flow Clarity

The logic now has two separate filters for the same collection:

const incompleteRuns = Array.from(latestByWorkflow.values()).filter(
  (run) => run.status !== 'completed'
);

// Later...
const completedRuns = Array.from(latestByWorkflow.values()).filter(
  (run) => run.status === 'completed'
);

Suggestion: Consider computing both in one pass to avoid iterating twice:

const latestRuns = Array.from(latestByWorkflow.values());
const incompleteRuns = latestRuns.filter(run => run.status !== 'completed');
const completedRuns = latestRuns.filter(run => run.status === 'completed');

This is a micro-optimization but improves readability by making it clear we're partitioning the same set.

---

🛡️ Security & Safety

✅ Safety Maintained

The PR correctly maintains safety by:

1. Still blocking on actual failures (completed workflows that failed)
2. Only relaxing the constraint on pending/running workflows
3. Preserving all failure detection logic (lines 143-149)

✅ No Security Concerns

This is a workflow control change with no security implications.

---

🧪 Test Coverage

Testing Strategy

The PR description mentions:

"Will be validated by the next docs-only merge to master"

Recommendation: While real-world validation is valuable, consider adding:

1. Unit tests for the JavaScript logic (if the action supports testing)
2. Documentation of the expected behavior in different scenarios

Manual Testing Checklist

Before merging, verify these scenarios work correctly:

• Docs-only commit when previous commit has running workflows → Should allow
• Docs-only commit when previous commit has failed workflows → Should block
• Docs-only commit when previous commit has completed successful workflows → Should allow
• Docs-only commit when previous commit has mixed state (some running, some failed) → Should block (failed ones exist)

---

📝 Documentation

Update CLAUDE.md Reference?

The PR fixes an issue mentioned in .claude/docs/master-health-monitoring.md:

"Understanding Workflow Reruns... Re-running a workflow does NOT change its conclusion in the GitHub API"

Consider adding a note about this PR's fix to that documentation file, explaining that the new logic handles running workflows more gracefully.

---

⚡ Performance

Minimal Impact

The change adds one additional filter operation (completedRuns), which is negligible given the small number of workflows per commit.

---

🎯 Overall Assessment

Recommendation: Approve with minor suggestions

This is a well-thought-out fix that:

• ✅ Solves a real bottleneck
• ✅ Maintains safety guarantees
• ✅ Includes clear documentation
• ✅ Has appropriate logging

Suggested Improvements (Optional)

1. Add comment explaining when jobs.length === 0 occurs
2. Consider computing completedRuns and incompleteRuns in one pass
3. Add a note to .claude/docs/master-health-monitoring.md about this improvement

Final Note

Great work on identifying and fixing this bottleneck! The circular dependency issue was a real pain point, and this solution is elegant and safe.

Code Review: Fix docs-only CI check to allow running workflows

Summary

This PR addresses a real bottleneck issue where docs-only commits were unnecessarily blocked by in-progress workflows. The solution is logically sound and well-implemented.

---

✅ Strengths

1. Excellent Problem Analysis

• Clear identification of the bottleneck: docs commits waiting for slow integration tests
• Strong rationale: running workflows haven't failed yet, so no reason to block
• Real-world example provided in the PR description

2. Code Quality

• Clean logic flow: The change properly separates incomplete runs (allowed) from completed runs (checked for failures)
• Improved comments: The new comments clearly explain the rationale (lines 86-89)
• Better error messages: Changed from core.setFailed to core.info for incomplete runs, which is semantically correct
• Maintained safety: Still blocks on actual failures from completed workflows

3. Defensive Programming

• Handles edge case where no jobs are found (line 124-127) - now logs a warning instead of treating as failure
• Provides informative logging for both scenarios (line 161-165)

---

🔍 Potential Issues & Suggestions

1. Edge Case: All Workflows Running (Low Risk)

Scenario: What if the previous commit has workflows still running, and a docs-only commit gets merged, but then those workflows fail?

Current behavior: The docs-only commit already merged successfully (CI was skipped). The failing workflows won't affect it.

Impact: The next non-docs commit will need to fix the issues. This is acceptable because:

• Docs-only commits don't change code, so they can't cause test failures
• The failing workflows will be visible on the master branch history
• The next real code commit will catch the failures

Suggestion: Consider adding a comment in the code explaining this scenario explicitly:

// Note: If workflows complete with failures AFTER we've allowed the docs-only skip,
// those failures will be caught and blocked on the next non-docs commit.
// This is safe because docs-only commits cannot introduce test failures.

2. Testing Strategy (Medium Importance)

The PR mentions "Logic verified" but doesn't specify how. Consider:

Manual testing scenarios to validate:

• ✅ Previous commit has running workflows → docs commit should be allowed
• ✅ Previous commit has completed workflows with failures → docs commit should be blocked
• ✅ Previous commit has completed workflows with success → docs commit should be allowed
• ✅ Mixed: some running, some completed with failures → should be blocked
• ✅ Mixed: some running, some completed with success → should be allowed

Suggestion: The next docs-only merge will validate the happy path. Consider pushing a deliberate test case with a failing workflow to ensure blocking still works.

3. Documentation (Low Priority)

The action description (line 2) says "unresolved test failures" but the new logic allows running workflows.

Suggestion: Update the description to be more precise:

description: Prevents docs-only commits from skipping CI when previous master commit has failed workflows (allows running workflows that haven't failed yet)

---

🎯 Performance & Security

✅ Performance: No issues. The change actually improves performance by not blocking unnecessarily.
✅ Security: No concerns. This is internal CI logic, not user-facing code.
✅ API Rate Limits: No additional API calls introduced.

---

🧪 Test Coverage

⚠️ No automated tests for GitHub Actions

This is common but risky. The logic is complex enough that unit tests would be valuable. Consider:

• Extracting the logic to a separate .js file that can be tested with Jest
• Mock GitHub API responses to test different scenarios
• This would prevent regressions during future changes

Not blocking for this PR, but worth considering for future improvements.

🚀 Recommendation

APPROVE with minor suggestions

The core logic is correct and safe. The suggestions above are enhancements, not blockers:

1. ✅ Merge as-is if you want to unblock the bottleneck immediately
2. 📝 Consider the documentation update (1-line change) to make the behavior crystal clear
3. 🧪 Future work: Add automated tests for this action to prevent regressions

---

💭 Final Thoughts

This is a well-thought-out fix to a real problem. The key insight—that running ≠ failing—is correct. The implementation properly maintains safety while eliminating the bottleneck.

The "wait for completion" approach was overly conservative, and this PR strikes the right balance: trust that running workflows will complete and catch issues on the next commit, while still blocking on known failures.

Great work! 🎉

Code Review: Fix docs-only CI check to allow running workflows

✅ Overall Assessment

This is a well-reasoned change that fixes a real bottleneck in the CI workflow. The logic change is sound and the implementation is clean.

---

🎯 Strengths

1. Excellent Problem Statement: The PR description clearly explains the issue with concrete examples
2. Well-Documented Code: The rationale is explained both in the PR and inline comments (lines 86-91)
3. Logical Fix: Distinguishing between "running" vs "failed" workflows is the right approach
4. Maintains Safety: Still blocks on actual failures, just removes false-positive blocks
5. Improved Logging: The core.info() messages clearly explain what's happening (lines 100-107, 161-165)

---

💡 Code Quality Observations

Good Practices

• ✅ Comprehensive comments explaining the logic change
• ✅ Filter for completedRuns is explicit and clear (lines 116-118)
• ✅ Changed core.setFailed() to core.info() appropriately (line 100)
• ✅ Removed early return to allow checking completed workflows (line 108)
• ✅ Better handling of edge case: no jobs found now logs warning vs treating as failure (lines 132-134)

Potential Improvements

1. Edge Case: All workflows are running (none completed)

// Current code at line 120:
for (const run of completedRuns) {
  // ...
}

// If completedRuns is empty, this loop doesn't execute
// and failingRuns.length === 0, so it succeeds

Observation: If all workflows are still running, completedRuns will be empty, the loop won't execute, and the check will pass. This is correct behavior per the PR's intent, but worth confirming it's intentional.

Recommendation: Add a comment around line 120 clarifying this is expected:

// If all workflows are still running, completedRuns will be empty and we'll allow the skip
// (no completed failures = safe to skip)
for (const run of completedRuns) {

2. Consider: Workflow failure notification

The comment at line 91 states:

If a workflow later fails, it will be caught on the next non-docs commit

Question: Is there any mechanism to notify maintainers if a workflow fails after a docs-only commit was allowed through? Or is the expectation that developers monitor master CI status independently?

Recommendation: Consider adding a note in the PR description about monitoring responsibilities.

---

🔍 Logic Verification

Let me trace through the key scenarios:

Scenario	Previous Behavior	New Behavior	Correct?
Previous commit: all workflows running	❌ Block docs-only	✅ Allow docs-only	✅ Yes
Previous commit: 1 failed, 2 running	❌ Block docs-only	❌ Block docs-only	✅ Yes
Previous commit: all completed, none failed	✅ Allow docs-only	✅ Allow docs-only	✅ Yes
Previous commit: 1 failed (completed)	❌ Block docs-only	❌ Block docs-only	✅ Yes

Logic checks out! ✅

---

🧪 Testing Considerations

Missing: There don't appear to be automated tests for this GitHub Action.

Recommendations:

1. This PR will be tested by the next docs-only merge (as mentioned in PR description)
2. Consider documenting test scenarios in the PR description for manual verification
3. Future enhancement: Consider adding tests using @actions/github mocking

Test scenarios to verify manually:

• Docs-only commit when previous commit has slow-running workflows
• Docs-only commit when previous commit has a failed workflow
• Docs-only commit when previous commit has mix of running + completed workflows

---

🔒 Security Considerations

✅ No security concerns:

• Uses actions/github-script@v7 (pinned version)
• Only reads workflow status via GitHub API
• Uses core.setFailed() appropriately for blocking cases
• No user input processing beyond commit SHAs from GitHub context

---

⚡ Performance Considerations

✅ Performance is good:

• Early exit optimization maintained (line 57-60)
• Filtering to completedRuns reduces API calls in the jobs loop (line 116)
• 7-day window limits pagination (line 29)
• Continues to use efficient pagination strategy

Minor improvement: The code now does slightly less work when workflows are running (doesn't fetch jobs for incomplete runs), which is actually a small performance win.

---

📝 Suggested Changes (Optional)

1. Clarify empty completedRuns behavior (.github/actions/ensure-master-docs-safety/action.yml:120)

+          // If all workflows are still running, completedRuns will be empty and we'll allow the skip
+          // (no completed failures = safe to proceed)
           for (const run of completedRuns) {

2. Consider adding a summary comment (top of file)
Add to action description (line 2):

-description: Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures
+description: Prevents docs-only commits from skipping CI when previous master commit has failed tests (running workflows are allowed)

Code Review: PR #2073 - Fix docs-only CI check to allow running workflows

✅ Overall Assessment

Verdict: Excellent work. This is a well-thought-out fix that addresses a real bottleneck while maintaining safety guarantees. The code quality is high, and the change is properly justified.

---

🎯 Strengths

1. Clear Problem Definition

The PR description excellently explains the circular dependency issue with concrete examples. The "before/after" code snippets make the change immediately understandable.

2. Sound Logic

The core insight is correct: running ≠ failing. Blocking on in-progress workflows was overly conservative and created unnecessary bottlenecks.

3. Safety Preserved

The change maintains the critical safety guarantee: docs-only commits are still blocked if completed workflows have actually failed. This is the right balance.

4. Excellent Documentation

• Inline comments explain the rationale (lines 86-91)
• Clear distinction between incomplete and completed runs
• Helpful logging messages for both cases (lines 161-165)

5. Code Quality

• Clean separation of concerns: incomplete check → completed check → failure analysis
• Proper use of core.info() vs core.setFailed()
• Maintained existing defensive patterns (empty jobs handling)

---

🔍 Detailed Analysis

Logic Flow (Improved)

Before:

Has incomplete runs? → BLOCK
Has failed completed runs? → BLOCK  
Otherwise → ALLOW

After:

Has incomplete runs? → LOG INFO, continue checking
Has failed completed runs? → BLOCK
Otherwise → ALLOW (with appropriate message)

This is objectively better UX without sacrificing safety.

Key Changes

1. Lines 96-109: Changed from core.setFailed() to core.info() for incomplete runs

   • ✅ Correct: In-progress workflows have not failed yet
   • ✅ Removed early return, allowing completed workflow check to proceed

2. Lines 116-118: Added explicit filtering for completed runs

   • ✅ Makes the code more explicit about what we are checking
   • ✅ Prevents duplicate checks of incomplete runs

3. Lines 131-134: Changed empty jobs handling from treating as failure to warning

   • ✅ More appropriate - missing jobs should not block docs commits
   • ✅ Warning still alerts to potential API/infrastructure issues

4. Lines 161-165: Enhanced success messaging

   • ✅ Distinguishes between "all complete, no failures" vs "some running, no failures"
   • ✅ Helps with debugging and understanding CI state

---

🤔 Considerations & Edge Cases

1. Race Condition (Theoretical)

Scenario: Docs commit merges while workflow is running → workflow fails seconds later.

Impact: Low

• Next non-docs commit will still run full CI
• Worst case: One docs-only commit sneaks through before a failure is known
• Failure will be caught on next commit
• This is acceptable given the UX improvement

2. Long-Running Workflows

Before: Docs commits blocked for hours waiting for slow integration tests
After: Docs commits can merge immediately
Impact: ✅ Massive improvement in developer experience

3. Empty Jobs Edge Case

The change from treating empty jobs as failures to warnings is correct, but consider:

• Q: Should we track if this warning occurs frequently?
• A: Current approach is fine - warnings will show in logs if it becomes a pattern

4. API Rate Limits

No additional API calls introduced. The existing pagination logic (lines 35-61) already handles rate limit concerns well with:

• 7-day window limit
• Early exit optimization
• per_page: 30 to reduce calls

---

🔬 Testing Considerations

Manual Testing Checklist

Based on CLAUDE.md, ensure these scenarios work:

• Scenario 1: Docs commit while workflows running → Should allow
• Scenario 2: Docs commit after workflow failure → Should block
• Scenario 3: Docs commit after workflow success → Should allow
• Scenario 4: Docs commit with mixed state (some complete/pass, some running) → Should allow

Recommendation: Test Scenario 4 with next docs-only commit to verify the mixed-state logging.

No Test Coverage Concerns

This is a GitHub Actions workflow - testing is primarily through real-world usage. The logic is straightforward enough that code review provides sufficient confidence.

---

🛡️ Security Considerations

No security concerns identified.

• No user input processing
• Uses official GitHub API via @actions/github-script
• No credential handling
• No external API calls

---

⚡ Performance Considerations

No performance regressions.

• Same API call pattern as before
• Slightly less blocking (allows docs commits earlier)
• No additional pagination or requests

Optimization note: Lines 116-118 create a new filtered array, but this is negligible given the small number of workflows (typically < 10).

---

🐛 Potential Bugs

None identified. The code is defensive and handles edge cases:

• ✅ Empty workflow runs list (line 63-66)
• ✅ Empty jobs list (line 131-135)
• ✅ Multiple reruns (deduplication lines 77-83)
• ✅ Mixed completion states (new logic handles correctly)

---

📋 Suggested Improvements (Optional)

Minor Enhancement: Add Metrics/Visibility

Consider adding a summary comment to track how often this new path is taken:

if (incompleteRuns.length > 0) {
  core.summary.addRaw(`ℹ️ Allowed docs-only skip with ${incompleteRuns.length} workflows still running`);
  await core.summary.write();
  // ... existing code
}

This would help track:

• How often docs commits benefit from this change
• Whether running workflows later fail (for future analysis)

Priority: Low - current logging is already good

---

📊 Changelog Compliance

Per CLAUDE.md guidelines:

• ✅ This is an infrastructure/CI improvement
• ✅ User-visible in the sense it affects developer workflow
• 🤔 Question: Should this be in CHANGELOG.md?

Recommendation: This could warrant a brief changelog entry under "Developer Experience" since it significantly improves docs contribution workflow. But per strict interpretation of "user-visible," it is borderline.

---

✨ Best Practices Adherence

Checking against CLAUDE.md requirements:

• ✅ Formatting: GitHub Actions YAML, no Ruby/JS formatting concerns
• ✅ Testing: Logic verified, will be validated on next docs merge
• ✅ Documentation: Excellent inline comments
• ✅ Security: No concerns
• ✅ Professional objectivity: Clear technical rationale, not over-promised

---

🎓 Learning Opportunity

This PR demonstrates excellent engineering judgment:

1. Identified root cause: Too conservative blocking
2. Found right balance: Safety vs developer experience
3. Documented rationale: Future maintainers will understand why
4. Iterative improvement: Building on PR Fix CI safety check to evaluate latest workflow attempt #2062 foundation

This is a textbook example of improving a safety check without compromising actual safety.

---

🏁 Final Verdict
