From 6ec4a252959ba60913e20ece2d7c0f0fc7cb8088 Mon Sep 17 00:00:00 2001 From: Beto Dealmeida Date: Tue, 7 Oct 2025 15:23:36 -0400 Subject: [PATCH 1/7] fix: prevent cache key mismatch by processing SQL expressions during validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root Cause: SQL expressions in adhoc metrics and orderby were being processed (uppercased via sanitize_clause()) during query execution, causing cache key mismatches in composite queries where: 1. Celery task processes and caches with processed expressions 2. Later requests compute cache keys from unprocessed expressions 3. Keys don't match → 422 error The Fix: Process SQL expressions during QueryObject.validate() BEFORE cache key generation, ensuring both cache key computation and query execution use the same processed expressions. Changes: - superset/common/query_object.py: * Add _sanitize_sql_expressions() called in validate() * Process metrics and orderby SQL expressions before caching - superset/models/helpers.py: * Pass processed=True to adhoc_metric_to_sqla() in get_sqla_query() * Skip re-processing since validate() already handled it - tests/unit_tests/connectors/sqla/test_orderby_mutation.py: * Add regression test documenting the fix --- superset/common/query_object.py | 66 +++++++++++++++++++ superset/models/helpers.py | 14 ++-- .../connectors/sqla/test_orderby_mutation.py | 61 +++++++++++++++++ 3 files changed, 133 insertions(+), 8 deletions(-) create mode 100644 tests/unit_tests/connectors/sqla/test_orderby_mutation.py diff --git a/superset/common/query_object.py b/superset/common/query_object.py index 0740ca889da5..21a22eed9bfa 100644 --- a/superset/common/query_object.py +++ b/superset/common/query_object.py @@ -285,6 +285,7 @@ def validate( self._validate_no_have_duplicate_labels() self._validate_time_offsets() self._sanitize_filters() + self._sanitize_sql_expressions() return None except QueryObjectValidationError as ex: if raise_exceptions: @@ -359,6 +360,71 @@ def _sanitize_filters(self) -> None: except QueryClauseValidationException as ex: raise QueryObjectValidationError(ex.message) from ex + def _sanitize_sql_expressions(self) -> None: + """ + Sanitize SQL expressions in adhoc metrics and orderby to ensure + consistent cache keys.

This commit: 1. Updates adhoc_metric_to_sqla() to apply template processing even when processed=True (meaning SQL is already sanitized) 2. Passes template_processor when converting orderby adhoc metrics 3. Removes obsolete test that expected error handling removed in commit add087cbfe The fix ensures that: - During validation: SQL is sanitized but Jinja templates are preserved (template_processor=None) - During execution: Jinja templates are rendered (template_processor provided, processed=True skips re-sanitization) Fixes test: test_chart_data_table_chart_with_time_grain_filter 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- superset/models/helpers.py | 5 +++ .../sqla/test_cache_key_stability.py | 37 ------------------- 2 files changed, 5 insertions(+), 37 deletions(-) diff --git a/superset/models/helpers.py b/superset/models/helpers.py index bbe2cfb1f9d9..c9415023ed15 100644 --- a/superset/models/helpers.py +++ b/superset/models/helpers.py @@ -1241,6 +1241,10 @@ def adhoc_metric_to_sqla( schema=self.schema, template_processor=template_processor, ) + elif template_processor and expression: + # Even if already processed (sanitized), we still need to + # render Jinja templates + expression = template_processor.process_template(expression) sqla_metric = literal_column(expression) else: @@ -1870,6 +1874,7 @@ def get_sqla_query( # pylint: disable=too-many-arguments,too-many-locals,too-ma col = self.adhoc_metric_to_sqla( col, columns_by_name, + template_processor=template_processor, processed=True, ) # use the existing instance, if possible diff --git a/tests/unit_tests/connectors/sqla/test_cache_key_stability.py b/tests/unit_tests/connectors/sqla/test_cache_key_stability.py index 10f164656e80..1ce77b7d155a 100644 --- a/tests/unit_tests/connectors/sqla/test_cache_key_stability.py +++ b/tests/unit_tests/connectors/sqla/test_cache_key_stability.py @@ -225,43 +225,6 @@ def process_expression(expression: str, **kwargs: Any) -> str: assert "}}" in query_obj.metrics[0]["sqlExpression"] -def test_validation_without_processing_methods(): - """ - Test that validation doesn't crash when datasource lacks processing methods. - """ - adhoc_metric = { - "expressionType": "SQL", - "sqlExpression": "sum(num)", - "label": "Sum", - } - - # Mock datasource WITHOUT _process_* methods - mock_datasource = Mock(spec=SqlaTable) - mock_datasource.database_id = 1 - mock_datasource.schema = "public" - - # Remove the processing methods - if hasattr(mock_datasource, "_process_select_expression"): - delattr(mock_datasource, "_process_select_expression") - if hasattr(mock_datasource, "_process_orderby_expression"): - delattr(mock_datasource, "_process_orderby_expression") - - # Create QueryObject - query_obj = QueryObject( - datasource=mock_datasource, - metrics=[adhoc_metric], - orderby=[(adhoc_metric, True)], - columns=[], - extras={}, - ) - - # Validate should not crash - query_obj.validate() - - # SQL should remain unchanged (no processing) - assert query_obj.metrics[0]["sqlExpression"] == "sum(num)" - - def test_validation_serialization_stability(): """ Test that serializing QueryObject metrics/orderby gives consistent results.
