Pull Request Overview

This PR removes legacy “stream event type” functionality and refactors the processing of SCMCreateStreamReq by adding new fields and adjusting serialization/deserialization flows. Key changes include:

• Updates in SCMCreateStreamReq encoding/decoding (e.g. new fields streamId, flags, tsmaId, placeHolderBitmap, and expanded sliding trigger parameters).
• Removal of legacy stream node tests and related node types, along with updates to built-in function classifications.
• Cleaning up client and parser structures by removing deprecated fields (e.g. streamRunHistory) and stream‐related fields in planner and nodes headers.

• The removal of test cases for stream session/window nodes is significant; please ensure that the new SCMCreateStreamReq functionality is covered by updated tests elsewhere.

TEST_F(NodesCloneTest, physiStreamSemiSessionWinodw) { ... }

source/libs/nodes/src/nodesUtilFuncs.c:1553

• The explicit freeing of pReq has been removed here; please confirm that memory allocated for SCMCreateStreamReq is now handled appropriately elsewhere to avoid potential memory leaks.

tFreeSCMCreateStreamReq(pStmt->pReq);

source/libs/function/src/builtins.c:2049

• [nitpick] The built-in function classifications have been updated by removing the FUNC_MGT_FORBID_STREAM_FUNC flag; please double-check that this change aligns with intended restrictions for stream functions.

.classification = FUNC_MGT_AGG_FUNC | FUNC_MGT_FORBID_STREAM_FUNC | FUNC_MGT_FORBID_SYSTABLE_FUNC,

source/common/src/msg/streamMsg.c:1527

• New sliding trigger fields (intervalUnit, slidingUnit, offsetUnit, soffsetUnit, and precision) have been added; please verify that the encoding order exactly matches the decoding order to avoid data inconsistencies.

TAOS_CHECK_EXIT(tEncodeI8(pEncoder, pReq->trigger.sliding.intervalUnit));
