Head commit for run: ba4f01944c5e3666153171d3ab972ceedbb612ab / Kaxil Naik <kaxiln...@gmail.com> Fix Jinja2 Template deep copy error with ``dag.test`` The `dag.test` method currently (in 3.0.2) clears dag runs before running ( [code](https://github.com/apache/airflow/blob/3.0.2/task-sdk/src/airflow/sdk/definitions/dag.py#L1092-L1097) ) the dag. For that it uses `SchedulerDAG.clear_dags`, which create `SchedulerDAG` from Task SDK DAG -- to do that it uses [`deepcopy.copy`](https://github.com/apache/airflow/blob/3.0.2/airflow-core/src/airflow/models/dag.py#L1797). Now that works for most cases, but not where `jinja2.Template` class is passed as a Task/Operator argument because of [this issue](https://github.com/pallets/jinja/issues/758). ```python In [1]: from copy import deepcopy ...: ...: from jinja2 import Template ...: ...: deepcopy(Template('')) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) Cell In[1], line 5 1 from copy import deepcopy 3 from jinja2 import Template ----> 5 deepcopy(Template('')) File ~/.local/share/uv/python/cpython-3.12.8-macos-aarch64-none/lib/python3.12/copy.py:162, in deepcopy(x, memo, _nil) 160 y = x 161 else: --> 162 y = _reconstruct(x, memo, *rv) 164 # If is its own copy, don't memoize. 165 if y is not x: File ~/.local/share/uv/python/cpython-3.12.8-macos-aarch64-none/lib/python3.12/copy.py:253, in _reconstruct(x, memo, func, args, state, listiter, dictiter, deepcopy) 251 if deep and args: 252 args = (deepcopy(arg, memo) for arg in args) --> 253 y = func(*args) 254 if deep: 255 memo[id(x)] = y File ~/.local/share/uv/python/cpython-3.12.8-macos-aarch64-none/lib/python3.12/copyreg.py:99, in __newobj__(cls, *args) 98 def __newobj__(cls, *args): ---> 99 return cls.__new__(cls, *args) TypeError: Template.__new__() missing 1 required positional argument: 'source' ``` This is a general issue that can affect any DAG using custom arguments that store or cache Jinja2 Template objects or similar. Clearly, the longer term solution for dag.test is to not use SchedulerDAG like that and instead call some task Execution endpoint to clear dagruns -- but this works for 3.0.x.
