[PR] fix(query_object_factory): normalize deprecated query fields before constructing QueryObject [superset]
eschutho opened a new pull request, #41204:
URL: https://github.com/apache/superset/pull/41204
## What changed
**Deprecation warning found in production Datadog logs:**
```
The field `groupby` is deprecated, please use `columns` instead.
file: query_object.py, line 219, func: _rename_deprecated_fields
env: production, service: superset
```
Charts with a stored `query_context` column (in `slices.query_context`) that was saved
using the old `groupby` key emit this warning on **every render** via
`Slice.get_query_context()`. That path parses the stored JSON and calls
`QueryContextFactory.create()` directly, bypassing the Marshmallow
`ChartDataQueryObjectSchema.rename_deprecated_fields` `@post_load` hook that the
REST API path relies on. By the time `QueryObject._rename_deprecated_fields` sees
`groupby` in `**kwargs`, there is no caller who can act on the warning — it is pure
noise in production logs.
## What was changed
`QueryObjectFactory.create()` now normalises `DEPRECATED_FIELDS` (the same set the
schema `@post_load` uses) **before** any downstream processing. This ensures that:
1. `groupby` (and `granularity_sqla`, `timeseries_limit`, `timeseries_limit_metric`)
are renamed to their canonical forms before `_process_time_range` reads `columns`
from `kwargs`.
2. `QueryObject._rename_deprecated_fields` never sees the old keys for the factory
path, so no warning is emitted.
3. If both the deprecated key and the canonical key are present, the canonical key
wins (`setdefault` semantics) — consistent with keeping explicitly-set values.
## No behavior change
Charts that use stored `query_context` with `groupby` continue to work exactly as
before. The only change is that the deprecation warning is no longer emitted for
these already-known-deprecated internal representations.
## Test plan
- [ ] New unit tests in `test_query_object_factory.py`:
- `test_deprecated_groupby_renamed_to_columns` — verifies `groupby` is silently
renamed to `columns` and not exposed as a `QueryObject` attribute.
- `test_deprecated_groupby_does_not_overwrite_columns` — verifies that an explicit
`columns` value takes precedence over a stale `groupby`.
- [ ] All existing `TestQueryObjectFactory` tests continue to pass.
- [ ] CI green.

<!-- Bito Reply -->
The suggestion to add an explicit return type hint to the newly added test method is correct, as it improves code clarity and adheres to type-checking standards. You can resolve this by adding `-> None:` to the method signature.
Here is the corrected code for the test method:
```python
def test_deprecated_groupby_renamed_to_columns(
self,
query_object_factory: QueryObjectFactory,
raw_query_context: dict[str, Any],
) -> None:
"""groupby in stored query_context should be silently renamed to columns."""
```
There are no other comments on this pull request to address.

Review Comment:
**Suggestion:** The deprecated-field normalization can drop valid `groupby`/deprecated values when the canonical key is present but null-like (for example `columns: None`). Because `setdefault` treats an existing `None` key as already set, the deprecated value is discarded after `pop`, so grouping can be silently lost and queries can return different results. Normalize with explicit precedence logic that still promotes deprecated values when the canonical field is missing or null-like, instead of unconditional `setdefault` on a possibly null existing key. [logic error]
<details>
<summary><b>Severity Level:</b> Major ⚠️</summary>
```mdx
- ❌ /superset/v1/query/ can ignore valid groupby columns.
- ⚠️ QueryContextFactory users risk losing grouping semantics.
- ⚠️ Aggregation queries may return ungrouped, inflated result sets.
```
</details>
<details>
<summary><b>Steps of Reproduction ✅ </b></summary>
```mdx
1. Use the legacy query endpoint `POST /superset/v1/query/` which is implemented in
`superset/views/api.py:8-22`. This endpoint reads `request.form["query_context"]` (line
16) and calls `QueryContextFactory.create(**json.loads(request.form["query_context"]))`
(lines 16-18).
2. In the request body, supply a `query_context` JSON where a query object contains both a
null-like canonical field and a populated deprecated field, for example:
```json
{
"datasource": {"id": 1, "type": "table"},
"queries": [{
"columns": null,
"groupby": ["country"],
"metrics": ["sum__value"]
}],
"result_type": "full",
"result_format": "json"
}
```
When `json.loads` runs in `Api.query`, this becomes a Python dict where the
single-element dict in `queries` has `{"columns": None, "groupby": ["country"],
"metrics": [...]}`.
3. The call stack proceeds into `QueryContextFactory.create` in
`superset/common/query_context_factory.py:38-48`, which iterates the `queries` list and
for each `query_obj` calls `self._query_object_factory.create(result_type,
datasource=datasource, server_pagination=server_pagination, **query_obj)` (lines 38-47).
For our example, `kwargs` in `QueryObjectFactory.create` contains both `columns=None` and
`groupby=["country"]`.
4. Inside `QueryObjectFactory.create` in `superset/common/query_object_factory.py:52-96`,
the deprecated-field normalization loop runs at lines 69-74:
```python
for field in DEPRECATED_FIELDS:
if field.old_name in kwargs:
if value := kwargs.pop(field.old_name):
kwargs.setdefault(field.new_name, value)
```
For the `DeprecatedField(old_name="groupby", new_name="columns")`, `field.old_name` is
`"groupby"` and `field.new_name` is `"columns"`. Since `"groupby"` is in `kwargs` with
value `["country"]`, `value` is truthy and `"groupby"` is popped. However, because
`"columns"` already exists in `kwargs` with value `None`, `kwargs.setdefault("columns",
["country"])` does nothing (dict `setdefault` does not overwrite an existing key even
if its value is `None`). The effect is:
- `groupby` is removed from `kwargs`.
- `columns` remains `None`.
When the function later constructs a `QueryObject` (lines 89-95), it passes
`columns=None`, so `QueryObject.__init__` in `superset/common/query_object.py:112-167`
sets `self.columns = columns or []` (line 142), resulting in `self.columns == []` and
no grouping. Prior to this PR, the same input would reach
`QueryObject._rename_deprecated_fields` in `superset/common/query_object.py:219-237`,
which would see `groupby` in `kwargs` and set `self.columns` from `groupby`, preserving
the grouping. Thus, a valid `groupby` configuration is silently dropped when `columns`
is present but null-like, changing query semantics and returned results.

This is a newly added Python test method, and it omits an explicit return type annotation. The surrounding code was changed, so the rule requiring new Python functions/classes to be fully typed applies here.
