Two Issues that are failing the Fabric Tests. These are code based.

AI Notes

1

Failing tests
tests/core/engine_adapter/integration/test_integration_fabric.py::test_create_drop_catalog
tests/core/engine_adapter/integration/test_integration.py::test_janitor[fabric-catalog]

What’s Wrong
Creating a Fabric warehouse that already exists should do nothing. Fabric used to return HTTP 400 for that; now it returns 409. Our code only handles 400, so it crashes.

Possible Fix
In sqlmesh/core/engine_adapter/fabric.py (create_warehouse): treat “already exists” (ItemDisplayNameAlreadyInUse) on 409 the same way as 400.

Failing tests
tests/core/engine_adapter/integration/test_integration.py::test_catalog_operations[fabric]
tests/core/engine_adapter/integration/test_integration.py::test_get_data_objects[[query]fabric]
tests/core/engine_adapter/integration/test_integration.py::test_get_data_objects[[df-pandas]fabric]

What’s Wrong
On Fabric, the default warehouse is stored as None. Other code expects a real name like ci_050fce7a, so .lower() crashes and get_data_objects returns objects with no catalog.

Possible Fix
In sqlmesh/core/engine_adapter/fabric.py: make get_current_catalog() return the real default DB name when you’re on default, instead of None.
