not really. exceptions are not shown and "nothing to do" kinda leaves up
nothing to imagination....
you can inspect the worker_stats column on the worker that is also a ticker
but I assume you won't find anything.
you can run this query to check for available tasks
sw, st, sd = db.scheduler_worker, db.scheduler_task, db.scheduler_task_deps
now = request.now
deps_with_no_deps = db(
(sd.can_visit == False) &
(~sd.task_child.belongs(
db(sd.can_visit == False)._select(sd.task_parent)
)
)
)._select(sd.task_child)
no_deps = db(
(st.status.belongs((QUEUED, ASSIGNED))) &
(
(sd.id == None) | (st.id.belongs(deps_with_no_deps))
)
)._select(st.id, distinct=True, left=sd.on(
(st.id == sd.task_parent) &
(sd.can_visit == False)
)
)
all_available = db(
(st.status.belongs((QUEUED, ASSIGNED))) &
((st.times_run < st.repeats) | (st.repeats == 0)) &
(st.start_time <= now) &
((st.stop_time == None) | (st.stop_time > now)) &
(st.next_run_time <= now) &
(st.enabled == True) &
(st.id.belongs(no_deps))
)
print all_available.select(st.ALL)
