From 85cc10b3cad94217d03fbd1bcf248aa4e249f1cf Mon Sep 17 00:00:00 2001 From: Annie Liang Date: Mon, 6 Apr 2026 19:45:30 -0700 Subject: [PATCH 01/27] fix: ensure CustomItemSerializer is not applied to internal query pipeline structures and is applied to SqlParameter serialization Fixes #45521 Bug 1: Changed PipelinedDocumentQueryExecutionContext to set DEFAULT_SERIALIZER instead of null on internal request options, preventing getEffectiveItemSerializer() from falling back to the client-level custom serializer for internal pipeline processing. This fixes ORDER BY, GROUP BY, aggregate, DISTINCT, DCount, and hybrid search queries when a custom serializer is configured on CosmosClientBuilder. Bug 2: Added serializer-aware parameter serialization in the query execution path so SqlParameter values are serialized with the effective custom serializer. SqlParameter now stores the raw value and re-serializes it when applySerializer() is called from PipelinedQueryExecutionContextBase.createAsync().

The fix should ensure that when the internal pipeline needs to bypass the custom serializer, it does so effectively. Two approaches: (A) Modify the internal pipeline contexts to explicitly force DEFAULT_SERIALIZER instead of relying on null propagation — e.g., pass an explicit 'useDefaultSerializer' flag or set the request-level serializer to DEFAULT_SERIALIZER instead of null, so getEffectiveItemSerializer returns DEFAULT_SERIALIZER (which is then replaced by ValueUnwrapCosmosItemSerializer). (B) Add a separate code path in getEffectiveItemSerializer or ParallelDocumentQueryExecutionContextBase that distinguishes between 'no custom serializer configured' and 'custom serializer deliberately suppressed for internal processing'. Approach (A) is simpler and less invasive — setting the request-level serializer to CosmosItemSerializer.DEFAULT_SERIALIZER instead of null would cause getEffectiveItemSerializer to return it immediately without falling through to the client default. Bug 2 Fix: SqlParameter needs access to the effective custom serializer. Since SqlParameter is created by user code before query execution, the serializer must be applied later. The approach is to re-serialize SqlParameter values using the effective custom serializer during query execution, either in SqlQuerySpec.populatePropertyBag() (if the serializer can be passed down) or in the query execution path where the effective serializer is known. This may require adding a new overload of SqlParameter.setValue() or JsonSerializable.set() that accepts a serializer, and calling it during query preparation.", + "files_to_modify": [ + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/implementation/query/PipelinedDocumentQueryExecutionContext.java", + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/models/SqlParameter.java", + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/implementation/JsonSerializable.java", + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/implementation/query/ParallelDocumentQueryExecutionContextBase.java", + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/implementation/query/DefaultDocumentQueryExecutionContext.java", + "sdk/cosmos/azure-cosmos/src/main/java/com/azure/cosmos/models/SqlQuerySpec.java" + ], + "files_to_create": [], + "test_strategy": "Add new test methods to CosmosItemSerializerTest covering: (1) ORDER BY queries with custom serializer on builder, (2) GROUP BY queries with custom serializer, (3) aggregate queries (COUNT, SUM) with custom serializer, (4) DISTINCT queries with custom serializer, (5) SqlParameter with date/custom-type values when custom serializer is configured — verify the parameter is serialized using the custom serializer and query results match.

SqlParameter.applySerializer() checks this flag instead of catching exceptions, so serializer bugs always propagate immediately. - CosmosItemSerializerNoExceptionWrapping sets canSerialize=false via bridge accessor (both Spark Scala and test Java versions) New test: - queryWithSqlParameterDateTimeAndCustomSerializer validates end-to-end scenario: custom serializer writes Instant as ISO-8601 string, SqlParameter applies same serializer so query filter matches stored value Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- ...mosItemSerializerNoExceptionWrapping.scala | 5 + ...smosItemSerializerNoExceptionWrapping.java | 5 + .../cosmos/CosmosItemSerializerTest.java | 96 +++++++++++++++++-- .../azure/cosmos/CosmosItemSerializer.java | 20 ++++ .../ImplementationBridgeHelpers.java | 5 + .../PipelinedQueryExecutionContextBase.java | 21 ++-- .../com/azure/cosmos/models/SqlParameter.java | 37 +++---- .../com/azure/cosmos/models/SqlQuerySpec.java | 5 + 8 files changed, 163 insertions(+), 31 deletions(-) diff --git a/sdk/cosmos/azure-cosmos-spark_3/src/main/scala/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.scala b/sdk/cosmos/azure-cosmos-spark_3/src/main/scala/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.scala index 5a64e065eac4..a354cee66efc 100644 --- a/sdk/cosmos/azure-cosmos-spark_3/src/main/scala/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.scala +++ b/sdk/cosmos/azure-cosmos-spark_3/src/main/scala/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.scala @@ -9,4 +9,9 @@ private[cosmos] abstract class CosmosItemSerializerNoExceptionWrapping extends C .CosmosItemSerializerHelper .getCosmosItemSerializerAccessor .setShouldWrapSerializationExceptions(this, false) + + ImplementationBridgeHelpers + .CosmosItemSerializerHelper + .getCosmosItemSerializerAccessor + .setCanSerialize(this, false) } diff --git a/sdk/cosmos/azure-cosmos-tests/src/test/java/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.java b/sdk/cosmos/azure-cosmos-tests/src/test/java/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.java index a2c15a5af177..7a79068bba7c 100644 --- a/sdk/cosmos/azure-cosmos-tests/src/test/java/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.java +++ b/sdk/cosmos/azure-cosmos-tests/src/test/java/com/azure/cosmos/CosmosItemSerializerNoExceptionWrapping.java @@ -14,5 +14,10 @@ public CosmosItemSerializerNoExceptionWrapping() { .CosmosItemSerializerHelper .getCosmosItemSerializerAccessor() .setShouldWrapSerializationExceptions(this, false);

The fix should ensure that when the internal pipeline needs to bypass the custom serializer, it does so effectively. Two approaches: (A) Modify the internal pipeline contexts to explicitly force DEFAULT_SERIALIZER instead of relying on null propagation — e.g., pass an explicit 'useDefaultSerializer' flag or set the request-level serializer to DEFAULT_SERIALIZER instead of null, so getEffectiveItemSerializer returns DEFAULT_SERIALIZER (which is then replaced by ValueUnwrapCosmosItemSerializer). (B) Add a separate code path in getEffectiveItemSerializer or ParallelDocumentQueryExecutionContextBase that distinguishes between 'no custom serializer configured' and 'custom serializer deliberately suppressed for internal processing'. Approach (A) is simpler and less invasive — setting the request-level serializer to CosmosItemSerializer.DEFAULT_SERIALIZER instead of null would cause getEffectiveItemSerializer to return it immediately without falling through to the client default. Bug 2 Fix: SqlParameter needs access to the effective custom serializer. Since SqlParameter is created by user code before query execution, the serializer must be applied later. The approach is to re-serialize SqlParameter values using the effective custom serializer during query execution, either in SqlQuerySpec.populatePropertyBag() (if the serializer can be passed down) or in the query execution path where the effective serializer is known.

The serialization path calls populatePropertyBag() which modifies the SqlQuerySpec's internal ObjectNode (backed by a non-thread-safe LinkedHashMap). Concurrent modification can corrupt the ObjectNode, producing malformed JSON with duplicate parameter entries that the server rejects with 'duplicate parameter name'. This fix creates a defensive copy of the SqlQuerySpec before serializing it for the query plan request. Each copy has its own property bag, eliminating the concurrent modification race.
