Pull request overview
This PR improves stack push throughput by running PR create/update operations concurrently while still preserving stacked dependencies via asyncio.Event coordination, and by limiting concurrent GitHub API calls with a semaphore.
Changes:
- Add per-change task objects (
ChangeTask) withasyncio.Eventsignaling to coordinate dependency PR number availability. - Execute create/update operations concurrently using
asyncio.gather, waiting only on the upstream PR number when needed. - Introduce a module-level semaphore limit (
MAX_CONCURRENT_API_CALLS = 5) to cap parallel GitHub API calls.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

@jd this pull request is now in conflict 😩 |
Use asyncio.Event to coordinate PR operations - each change waits only for its dependency's PR number to be resolved. Updates with existing PRs signal immediately, allowing downstream tasks to proceed in parallel. Add semaphore to limit concurrent GitHub API calls (default 5).
