From the behavior you mentioned, it seems that whether I use
execution_timeout or timeout to set _timeout_sec, they both lead to the same
termination conditions. Upon further reflection, I'm questioning the need for
explicitly checking if the dag_run is in a running state using _timeout_sec.
This check appears to produce an outcome that overlaps with what is already
achieved through the existing timeout parameter of ExeternalTaskSensor.
I want to change the async def run method internal loop logic like following
.
FROM
```python
while True:
delta = utcnow() - self.trigger_start_time
if delta.total_seconds() < self._timeout_sec:
# mypy confuses typing here
if await self.count_running_dags() == 0: # type: ignore[call-arg]
self.log.info("Waiting for DAG to start execution...")
await asyncio.sleep(self.poll_interval)
else:
yield TriggerEvent({"status": "timeout"})
return
# mypy confuses typing here
if await self.count_tasks() == len(self.execution_dates): # type:
ignore[call-arg]
yield TriggerEvent({"status": "success"})
return
self.log.info("Task is still running, sleeping for %s seconds...",
self.poll_interval)
await asyncio.sleep(self.poll_interval)
```
TO
```python
while True:
if await self.count_running_dags() == 0: # type: ignore[call-arg]
self.log.info("Waiting for DAG to start execution...")
await asyncio.sleep(self.poll_interval)
# mypy confuses typing here
if await self.count_tasks() == len(self.execution_dates): # type:
ignore[call-arg]
yield TriggerEvent({"status": "success"})
return
self.log.info("Task is still running, sleeping for %s seconds...",
self.poll_interval)
await asyncio.sleep(self.poll_interval)
```
Instead of making immediate changes, I try adding a deprecation message in
this PR. I believe this approach will allow for a smoother transition and
provide users with adequate notice before the functionality is eventually
removed.
If there's anything I've misunderstood, please let me know.
