GNU ld extracts object files only once per library scan; by the time the second `libextconnector.a` is processed, `libnodes.a` has already been scanned and `nodesRemotePlanToSQL` is not retained. Fixed by adding `-Wl,--undefined=nodesRemotePlanToSQL` to `taosudf` (enterprise Linux only), which forces the linker to extract that TU from `libnodes.a` on first encounter. 2. `taosmqtt` / `topic-producer`: `libcurl.a` (ext_curl) is built against the internal OpenSSL (ext_ssl). When `5569f0000b1` moved `ext_curl` to all platforms and added `DEP_ext_curl(common)`, it added the Windows-specific extra libs (`crypt32`, etc.) but omitted the Linux/macOS equivalents (`libssl.a`, `libcrypto.a`). Fixed by appending `ext_ssl_libs` in `DEP_ext_curl_LIB` for non-Windows. --- cmake/external.cmake | 7 +++++++ source/libs/function/CMakeLists.txt | 10 ++++++++++ 2 files changed, 17 insertions(+) diff --git a/cmake/external.cmake b/cmake/external.cmake index a9abb03ffd07..172daf460072 100644 --- a/cmake/external.cmake +++ b/cmake/external.cmake @@ -139,6 +139,13 @@ macro(INIT_EXT name) # { if("z${name}" STREQUAL "zext_curl") target_link_libraries(${tgt} PRIVATE crypt32 wldap32 normaliz secur32 bcrypt) endif() + else() + if("z${name}" STREQUAL "zext_curl") + # ext_curl is built with OpenSSL; link ssl/crypto so consumers resolve those symbols + foreach(v ${ext_ssl_libs}) + target_link_libraries(${tgt} PRIVATE "${v}") + endforeach() + endif() endif() add_definitions(-D_${name}) diff --git a/source/libs/function/CMakeLists.txt b/source/libs/function/CMakeLists.txt index c088113c76e6..43d0cec81484 100644 --- a/source/libs/function/CMakeLists.txt +++ b/source/libs/function/CMakeLists.txt @@ -61,6 +61,16 @@ target_link_libraries( PRIVATE os util common nodes function dnode ) +if(TD_ENTERPRISE AND UNIX AND NOT APPLE) + # libextconnector.a references nodesRemotePlanToSQL (in libnodes.a). + # libextconnector.a appears twice in the transitive link command; the object file that + # holds nodesRemotePlanToSQL is only extracted from the second occurrence (after libnodes.a + # has already been scanned).

charset=UTF-8 Content-Transfer-Encoding: 8bit - catalogInt.h: add CTG_OP_REPLACE_EXT_SOURCE_CACHE operation and SCtgReplaceExtSourceCacheMsg; declare ctgOpReplaceExtSourceCache and ctgReplaceExtSourceCacheEnqueue - ctgCache.c: implement ctgOpReplaceExtSourceCache which atomically swaps the entire pExtSourceHash and updates extSrcGlobalVer on the write thread; add ctgBuildNewExtSourceHash (called on HB thread to amortise allocation); add ctgExtSourceHashFreeFp to bind SExtSourceCacheEntry lifetime to hash-node ref-count; add comments on thread-safety of ctgFreeExtDbCache / ctgFreeExtSourceCacheEntry - ctgAsync.c: implement ctgReplaceExtSourceCacheEnqueue — deep-copies pSources and enqueues a single REPLACE op so the HB thread does not block on catalog write serialisation - catalog.c: catalogUpdateAllExtSources now calls ctgReplaceExtSourceCacheEnqueue instead of per-entry upsert - ctgRemote.c: propagate globalVer from SExtSourceHbRsp into catalog - clientHb.c: add error-log coverage for deserialization failure, catalogUpdateAllExtSources failure, alloc failure, and hash-put failure; expand error path for catalogGetExtSrcGlobalVer - clientImpl.c: check and warn (non-fatal) on catalogRemoveExtSource failures in handleExtSourceError and REFRESH pre-clear path --- source/client/src/clientHb.c | 30 +- source/client/src/clientImpl.c | 23 +- source/libs/catalog/inc/catalogInt.h | 72 ++++- source/libs/catalog/src/catalog.c | 77 +---- source/libs/catalog/src/ctgAsync.c | 179 ++++++++---- source/libs/catalog/src/ctgCache.c | 405 ++++++++++++++++++++++++--- source/libs/catalog/src/ctgRemote.c | 6 + 7 files changed, 609 insertions(+), 183 deletions(-) diff --git a/source/client/src/clientHb.c b/source/client/src/clientHb.c index 697170725479..2050be34d35c 100644 --- a/source/client/src/clientHb.c +++ b/source/client/src/clientHb.c @@ -534,6 +534,7 @@ static int32_t hbProcessExtSourceInfoRsp(void *value, int32_t valueLen, struct S SExtSourceHbRsp hbRsp = {0};

18:06:24 +0800 Subject: [PATCH 28/37] feat: client-side async retry on ext-source pool exhaustion query.h: - split TSDB_CODE_EXT_RESOURCE_EXHAUSTED out of NEED_CLIENT_RM_EXT_SOURCE_ERROR into a new dedicated macro NEED_CLIENT_RETRY_EXT_POOL_ERROR; add it to NEED_CLIENT_HANDLE_EXT_ERROR so pool-exhaustion is handled separately from source-not-found errors clientInt.h: - add extPoolRetry counter to SRequestObj for pool-exhaustion retry tracking - export handleExtSourceError for use in clientMain.c clientImpl.c: - implement async pool-exhaustion retry via a dedicated timer (tscExtPoolTimer, lazily initialised via pthread_once) - extPoolRetryTimerCb acquires the request by ref ID (not pointer), resets pRequest->retry, then calls restartAsyncQuery - handleExtSourceError handles NEED_CLIENT_RETRY_EXT_POOL_ERROR by scheduling a 1-second delayed retry (max EXT_POOL_RETRY_MAX_TIMES=5) clientMain.c: - call handleExtSourceError early in handleQueryAnslyseRes and doAsyncQueryFromParse so EXT errors are intercepted before the generic NEED_CLIENT_HANDLE_ERROR path ctgAsync.c / federatedscanoperator.c: - add comments clarifying that TSDB_CODE_EXT_RESOURCE_EXHAUSTED propagates to the user callback and retries must use ref ID asynchronously extConnectorInt.h: - clarify idleCount comment: approximate (soft cap), not exact ---

[PATCH 29/37] test: add FQ stability test suite and pool-exhaustion test infrastructure test_fq_09_stability.py: - new test class TestFq09Stability covering four stability areas: (1) continuous query mix (single-source / cross-source JOIN / vtable) (2) fault injection (unreachable source, slow query, throttle, jitter) (3) cache stability (meta/capability cache repeated expiry + REFRESH) (4) connection-pool stability (high-frequency burst queries) - each area runs as a short representative cycle in CI; iteration counts controllable via FQ_STAB_* environment variables - pool-exhaustion test uses fq_pool_test MySQL user (MAX_USER_CONNECTIONS=1) to trigger TSDB_CODE_EXT_RESOURCE_EXHAUSTED and verify client retry recovery ensure_ext_env.sh: - create pool-exhaustion test user

charset=UTF-8 Content-Transfer-Encoding: 8bit plannodes.h / nodesCloneFuncs.c / nodesUtilFuncs.c: - add pRemoteLogicPlan field to SScanLogicNode: holds the chain of pushed-down Sort/Project logic nodes (topmost first, set by FqPushdown); physical plan generation converts it to SFederatedScanPhysiNode.pRemotePlan - wire CLONE_NODE_FIELD and nodesDestroyNode for the new field planOptimizer.c — FqPushdown rule (Phase 1): - add OPTIMIZE_FLAG_FQ_PUSHDOWN flag; register 'FqPushdown' rule at end of optimizeRuleSet so it runs after all other rules - fqFindExternalScan: DFS find the first unprocessed SCAN_TYPE_EXTERNAL node - fqPushdownOptimize: collect consecutive pushdownable single-child ancestors (Sort / Project) of the external scan, rewire main tree to replace topmost with the scan, disconnect bottommost from the scan, hand the detached chain to pScan->pRemoteLogicPlan - add Phase 2 stubs (fqHarvestConditions / fqConvertPartition / fqConvertWindow / fqHarvestAgg / fqHarvestLimit / fqMergeJoin / fqPushdownSubquery) as no-ops; replace the old 'skip all optimizer rules' bypass with real logic - add FQ guards in existing optimizer passes (scanPathOpt, pdcDealScan, eliminateNotNullCond, sortPriKeyOpt, partTagsIsOptimizableNode, pushDownLimitTo) to prevent incorrect optimization of external scan nodes planPhysiCreater.c: - add remoteLogicNodeToPhysi: convert one Sort/Project logic node to its physi counterpart and wire pChild as its single child; propagate LIMIT from the logic node down to pLeaf (SFederatedScanPhysiNode) if not set - add buildRemotePlanFromLogicPlan: collect pRemoteLogicPlan chain top-down, then convert bottom-up with pLeaf as initial bottom; on error leave the partial chain for caller cleanup - call buildRemotePlanFromLogicPlan inside createFederatedScanPhysiNode to populate SFederatedScanPhysiNode.pRemotePlan from pRemoteLogicPlan --- include/libs/nodes/plannodes.h | 5 + source/libs/nodes/src/nodesCloneFuncs.c | 1 + source/libs/nodes/src/nodesUtilFuncs.c | 1 + source/libs/planner/src/planOptimizer.c | 199 ++++++++++++++++- source/libs/planner/src/planPhysiCreater.c | 242 +++++++++++---------- 5 files changed, 326 insertions(+), 122 deletions(-) diff --git a/include/libs/nodes/plannodes.h b/include/libs/nodes/plannodes.h index 18b7fd234b8d..8a0be6b6e301 100644 --- a/include/libs/nodes/plannodes.h +++ b/include/libs/nodes/plannodes.h @@ -152,6 +152,11 @@ typedef struct SScanLogicNode { SNodeList* pFqSortKeys;

Key changes per file: federated_query_common.py - Add _fmt_result_table() to render actual-vs-expected row-by-row diff - assert_query_result: show full table diff on row count or cell mismatch - _assert_error_not_syntax / _assert_external_context: include errno (hex) and error_info string in failure messages - assert_plan_contains: dump full numbered plan on keyword-not-found test_fq_13_explain.py - _get_explain_output: capture errno/error_info on query failure - _assert_contain / _assert_not_contain: dump full numbered output on failure - _get_remote_sql_line: dump full output when Remote SQL line is missing - _assert_no_local_operator: show offending line + full plan on failure - _check_analyze_metrics: show both plain and ANALYZE outputs on failure - _assert_remote_sql_kw / _assert_remote_sql_no_kw: raise AssertionError test_fq_14_result_parity.py - _get_rows: catch query errors and surface SQL + errno + error_info - Add _fmt_result_tables() for side-by-side local vs external diff with X - _compare_rows: show full table diff on row count, col count, or value mismatch test_fq_08_system_observability.py - assert found: add source name to all 5 bare assert found statements - row[col] == value: add actual/expected to assertion messages test_fq_01_external_source.py -
