fix(orchestration): guard against ZeroDivisionError in RetryFailedTasks when retry_jitter_factor is set without retry_delay `RetryFailedTasks.after_transition` passes `base_delay` directly to `clamped_poisson_interval` when `retry_jitter_factor` is configured, but `clamped_poisson_interval(0, ...)` divides by zero in its exponential CDF computation, crashing the orchestration server. This happens whenever a task uses `@task(retries=N, retry_jitter_factor=X)` without specifying `retry_delay_seconds` (the default). In that case `run_settings.retry_delay` is `None`, which normalises to `base_delay = 0`, and the subsequent call to `clamped_poisson_interval` raises `ZeroDivisionError`. Fix: skip jitter and use `base_delay` directly when `base_delay == 0`. Jitter on a zero-second delay is meaningless anyway. A regression test `test_jitter_with_zero_delay_does_not_raise` is added to `TestRetryFailedTasks` to cover this path.

fix: worker-channel ready frame returns `worker_id=None` (#22067)

main

1 day ago

fix: OSS worker-channel ready frame returns worker_id=None The new OSS WebSocket channel was returning worker.id in the worker.ready.v1 frame, causing workers to set backend_id and PREFECT__WORKER_ID unnecessarily. This matches the REST heartbeat behavior where OSS does not return a worker ID to the client. - Set worker_id to None in the OSS worker.ready.v1 payload - Keep internal worker heartbeat recording unchanged - Add tests verifying OSS ready frame has worker_id=None - Add tests verifying PREFECT__WORKER_ID is not set via channel path - Add protocol test confirming on_worker_id callback is not invoked Co-authored-by: Alex Streed <alex.s@prefect.io> Co-Authored-By: alex.s <ajstreed1@gmail.com>
