Return response to Github in time, run our process as BackgroundTasks

[myakove]

Github webhook need answer in 10 seconds, otherwise it report time out.
We return 200 if we got the hook and all check passed, otherwise we return error.

Summary by CodeRabbit

• Refactor
  • Webhook processing now runs asynchronously in the background, enabling quicker responses upon webhook receipt and improved error logging.

Walkthrough

The process_webhook endpoint in webhook_server/app.py was modified to accept a BackgroundTasks parameter and now schedules webhook processing as a background task instead of awaiting its completion, allowing the HTTP response to return immediately while processing continues asynchronously. Error handling was added inside the background task to log exceptions.

Changes

File(s)	Change Summary
webhook_server/app.py	Updated process_webhook function signature to include BackgroundTasks. Replaced direct await of api.process() with scheduling it as a background task wrapped in error handling. Endpoint now returns immediately.

11-11: Import of BackgroundTasks looks good

This import is necessary to utilize FastAPI's background task functionality, which is essential for the PR objective of responding to GitHub quickly while processing webhooks asynchronously.

124-124: Function signature correctly updated for background tasks

The function signature has been properly updated to accept the background_tasks parameter injected by FastAPI's dependency injection system. This is the correct pattern for implementing background tasks in FastAPI.

webhook_server/app.py (1)

153-154: Consider returning the actual task details in the response.

The response currently returns a success status regardless of the actual outcome of the background processing.

Consider including the delivery ID or some other reference in the response that could be used to query the status of the background task later:

         background_tasks.add_task(api.process)
-        return {"status": requests.codes.ok, "message": "process success", "log_prefix": delivery_headers}
+        return {"status": requests.codes.ok, "message": "webhook received, processing started", "delivery_id": delivery_id, "log_prefix": delivery_headers}

11-11: LGTM! Import added for background task implementation.

The import of BackgroundTasks from FastAPI is necessary to implement the asynchronous processing approach described in the PR objectives.

---

124-124: LGTM! Function signature updated appropriately.

The function signature has been updated to include background_tasks: BackgroundTasks parameter, which FastAPI will automatically inject. This change is required to implement background processing.
