Two paths caused the scheduler to interrupt a running background task when the frontend Activity view polled for status: 1. GET /api/tasks/runs/recent was not in _PASSIVE_EXACT_PATHS, so _InteractiveActivityMiddleware treated it as a foreground request and called stop_background_tasks_for_foreground, cancelling any in-flight scheduled task. Add it to _PASSIVE_EXACT_PATHS alongside the other read-only polling endpoints. 2. The /api/activity/heartbeat handler called stop_background_tasks_for_foreground unconditionally, ignoring BACKGROUND_TASK_FOREGROUND_GATE=false. Wrap the call in a _gate_enabled() guard so the env var fully disables heartbeat- triggered cancellations.

"""Regression: read-only task-status polling must not interrupt running background tasks.
|
|
|
|
GET /api/tasks/runs/recent is called by the Activity view while a scheduled
|
|
task is executing. Before this fix, the _InteractiveActivityMiddleware treated
|
|
it as a foreground request and called stop_background_tasks_for_foreground,
|
|
which immediately cancelled the running task. The fix adds the endpoint to
|
|
_PASSIVE_EXACT_PATHS so it is excluded from interactive tracking.
|
|
|
|
Additionally, /api/activity/heartbeat called stop_background_tasks_for_foreground
|
|
unconditionally, ignoring BACKGROUND_TASK_FOREGROUND_GATE=false. The fix wraps
|
|
that call in a _gate_enabled() check so the env var fully disables interrupts.
