Thank for the MR!
I had written the alembic migrations, but couldn't figure a good way to add
tests.
Easiest way seemed to add a big dag exceeding 65Kb limit in example dags but
that didn't seem ideal.
Tried adding test case in test_dagcode on the lines of:
```
def test_storing_large_dag_file_in_db(self):
"""Test if large dag exceeding 65Kb size can be added to db"""
with TemporaryDirectory(prefix='airflow_dagcode_dir') as tmp_dir:
with NamedTemporaryFile(dir=tmp_dir, mode='w', suffix='.py') as
f:
f.write(get_large_test_dag())
f.flush()
f.close()
import os
os.listdir(tmp_dir)
dag_bag = DagBag(tmp_dir)
for dag in dag_bag.dags.values():
DagCode(dag.fileloc, get_large_test_dag()).sync_to_db()
dag.sync_to_db()
```
but this wasn't writing dag code to db as I had expected.
