- Around line 417-425: The as_completed loop currently lets any task exception
escape and abort the search: wrap the await coro inside a try/except so per-task
exceptions are caught/logged and the loop continues to the next completed task
(refer to the asyncio.as_completed(tasks) loop and the local variable
coro/result handling). In the finally block, after cancelling unfinished tasks
(tasks.cancel() calls), await/drain all tasks to completion using
asyncio.gather(*tasks, return_exceptions=True) and suppress or handle
CancelledError/other exceptions so there are no pending-task warnings (refer to

returned immediately when found.

Handle per-task failures and drain cancelled tasks before exit.
At line 418, any exception from one secret-check task aborts the whole loop, even if another candidate would succeed.
At line 424, tasks are cancelled but never awaited, leaving cleanup non-deterministic and risking pending-task warnings.

Confidence score: 3/5
- There is a concrete reliability risk in
streamrip/client/qobuz.py: an unexpected exception from one_test_secrettask can escape theawaitloop and prevent remaining candidates from being tested, which may cause valid secrets to be skipped. - Task lifecycle handling in
streamrip/client/qobuz.pyis incomplete on early return; cancelled pending/done tasks are not awaited, so exceptions can go uncollected and surface later as noisy async warnings or hidden failures. - Given two medium-severity, high-confidence async-control-flow issues in the same path, this carries some merge risk and is worth addressing before relying on it in production.
- Pay close attention to
streamrip/client/qobuz.py- exception handling and task cleanup around secret-check coroutines need to be made robust.

💡 What: Refactored
_get_valid_secretinstreamrip/client/qobuz.pyto useasyncio.as_completed()and atry...finallyblock for task cancellation, rather thanasyncio.gather().🎯 Why: Previously,
asyncio.gathersent concurrent requests for all available secrets but forced the event loop to wait until every single request completed before returning a result. By usingasyncio.as_completed(), we process the tasks as they finish. Once the first valid secret responds, we immediately return it and explicitly cancel the rest of the pending requests.📊 Impact: Significantly reduces latency when fetching a valid Qobuz API secret, especially if there are slow or timing-out secrets in the list. Reduces unneeded network I/O and prevents background task leakage.
🔬 Measurement: Run the test suite (
PYTHONPATH=. poetry run pytest tests) to ensure Qobuz authentication and secret retrieval still pass successfully.PR created automatically by Jules for task 11812820950230207374 started by @davidjuarezdev
Summary by Sourcery
