dv-matthew-crown opened a new issue, #55225:
URL: https://github.com/apache/airflow/issues/55225
### Apache Airflow version
3.0.6
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
The short circuit operator does not skip mapped tasks when trigger rule is
set to none_failed and ignore_downstream_trigger_rules is set to True
### What you think should happen instead?
I would expect that mapped task instances would be skipped if the short
circuit task returns a False value, but instead they are executed
### How to reproduce
```from airflow.sdk import Asset, dag, task
a = Asset("test_tmp_dag")
b = Asset("test_tmp_dag2")
@dag(dag_id="test_tmp_dag", schedule=None, default_args={"trigger_rule":
"none_failed"})
def test_tmp_dag():
multi = [1,2,3]
@task.short_circuit(task_id="dummy1",
ignore_downstream_trigger_rules=True)
def dummy1():
if 2 == 2:
return False
else:
return "dummy1"
@task(task_id="dummy2")
def dummy2():
return "dummy2"
@task(task_id="dummy3")
def dummy3(x: int):
return f"dummy3-{x}"
@task(task_id="publish", outlets=[a,b])
def publish():
return "published"
d1 = dummy1()
d2 = dummy2()
d3 = dummy3.expand(x=multi)
p = publish()
# The result of the task function call is a Task object
d1 >> d2 >> d3 >> p
test_tmp_dag()
```
This dag demonstrates the problem - dummy2 and publish are correctly
skipped, but the mapped tasks in dummy3 are executed.
