💡 What: Refactored _filter_to_still_open_prs to check PR open statuses concurrently using ThreadPoolExecutor.map.
🎯 Why: gh pr view subprocess calls are slow and were previously executed sequentially for each PR, causing N+1 delays when managing large numbers of PRs.
📊 Impact: Checking states of multiple PRs executes much faster by parallelizing the network calls while correctly preserving order and exceptions.
🔬 Measurement: Look for faster overall loop execution times in logs with fewer bottlenecks when handling numerous PRs. Checkout branch, pass a list of PR numbers to _filter_to_still_open_prs and monitor real-world time elapsed.

📝 Walkthrough

Summary by CodeRabbit

  • Documentation

    • Added documentation describing an optimized approach to GitHub PR status checking.
  • Refactor

    • Enhanced PR validation performance by implementing concurrent execution for status checks, reducing overall latency when validating multiple pull requests while maintaining existing error handling and logging behavior.

Walkthrough

This PR optimizes GitHub PR validation latency by replacing sequential gh pr view calls with concurrent execution via ThreadPoolExecutor. The approach is documented, and the CLI's _filter_to_still_open_prs function is updated to use thread-pool-based concurrent mapping while preserving per-PR error handling and result order.

Changes

Concurrent PR Status Validation

Layer / File(s) Summary
Concurrent PR status checking with ThreadPoolExecutor
.jules/bolt.md, ralph_loop/cli.py
Documentation explains using executor.map for concurrent gh pr view calls with order preservation. Implementation replaces sequential loop in _filter_to_still_open_prs with thread-pool execution, maintaining per-PR error handling and logging ("Could not confirm… keeping it" vs. "skipping fan-out spawn").

Poem

🐰 Sequential loops, so slow and plain,
Now threads run wild through the PR domain!
ThreadPoolExecutor brings the speed,
Order preserved—all that we need.
Concurrency wins, no more N+1 pain! ✨

P2 Badge Avoid bursting gh state probes before fan-out

When the initial fan-out list contains many PRs, this starts up to 10 simultaneous gh pr view calls before any PR child is spawned. The wrapper I checked treats GitHub rate-limit responses, including secondary rate limits, by sleeping 300s and retrying in _gh_run_with_retry (gh_ops.py lines 78-87), so a burst that trips that path can stall the entire supervisor startup for minutes before any useful work begins. Please cap this much lower or otherwise throttle/honor rate limits for these probes.

P2 Badge Preserve interrupt responsiveness during PR filtering

If the supervisor is interrupted while this iterator is waiting on gh pr view workers, the with ThreadPoolExecutor(...) context manager waits for all already-started workers to finish before unwinding. In the common failure mode this filter is meant to handle—slow or stuck GitHub/network calls—a Ctrl-C or supervisor stop during initial fan-out can now hang until every in-flight probe completes, whereas the previous single foreground subprocess was interrupted immediately. Use explicit shutdown/cancellation or keep the signal-sensitive startup path synchronous.

P2 Badge Remove generated Jules note from commit

This new .jules/bolt.md file appears to be an auto-generated Jules learning note rather than project source or user-facing documentation, and the repository instructions for this checkout say not to commit generated local artifacts or assistant-generated boilerplate. Keeping it in the patch adds tool metadata unrelated to Ralph behavior; please drop it from the commit.
