[fix](delete) Fix static type dispatch by mistake due to typo (apache…
…#42260) (apache#43488) ### What problem does this PR solve? Problem Summary: DeletePredicatePB should be DeleteSubPredicatePB. Test case is too ambiguous to add, since this bug is triggered by a huge random test and failed to find the minimal case. However, this fix is verified under the wild test that it does works. Note that this problem may be triggered by another bug, cuz schema in delete predicate rowset should contain column referred in delete condition. Even if we don't have this fix, this error should never happend. But this error occurred under wild tests, means that schema in delete predicate rowset is not adaptable with delete condition. I think it is under some status that delete operation use BE tablet schema rather than schema from FE, and the former rename operation result in that status. But I failed to add a test case to reproduce, and think that by no way will it happend occurding to the related code. ``` (1105, 'errCode = 2, detailMessage = ([172.20.50.7](http://172.20.50.7/))[INTERNAL_ERROR]failed to initialize storage reader. tablet=78026, res=[INTERNAL_ERROR]column not found, name=loc1, table_id=-1, schema_version=2 \t0# doris::TabletSchema::column(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:375 \t1# doris::Status doris::DeleteHandler::_parse_column_pred<doris::DeleteSubPredicatePB>(std::shared_ptr<doris::TabletSchema>, std::shared_ptr<doris::TabletSchema>, google::protobuf::RepeatedPtrField<doris::DeleteSubPredicatePB> const&, doris::DeleteConditions*) at /home/zcp/repo_center/doris_master/doris/be/src/util/expected.hpp:1986 \t2# doris::DeleteHandler::init(std::shared_ptr<doris::TabletSchema>, std::vector<std::shared_ptr<doris::RowsetMeta>, std::allocator<std::shared_ptr<doris::RowsetMeta> > > const&, long) at /var/local/ldb-toolchain/bin/../lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/bits/shared_ptr_base.h:701 \t3# doris::TabletReader::_init_delete_condition(doris::TabletReader::ReaderParams const&) at /var/local/ldb-toolchain/bin/../lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/bits/shared_ptr_base.h:701 \t4# doris::TabletReader::_init_params(doris::TabletReader::ReaderParams const&) at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:499 \t5# doris::TabletReader::init(doris::TabletReader::ReaderParams const&) at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:499 \t6# doris::vectorized::BlockReader::init(doris::TabletReader::ReaderParams const&) at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:499 \t7# doris::vectorized::NewOlapScanner::open(doris::RuntimeState*) at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:499 \t8# doris::vectorized::ScannerScheduler::_scanner_scan(std::shared_ptr<doris::vectorized::ScannerContext>, std::shared_ptr<doris::vectorized::ScanTask>) at /home/zcp/repo_center/doris_master/doris/be/src/common/status.h:388 \t9# std::_Function_handler<void (), doris::vectorized::ScannerScheduler::submit(std::shared_ptr<doris::vectorized::ScannerContext>, std::shared_ptr<doris::vectorized::ScanTask>)::$_1::operator()() const::{lambda()#1}>::_M_invoke(std::_Any_data const&) at /var/local/ldb-toolchain/bin/../lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/bits/shared_ptr_base.h:701 \t10# doris::ThreadPool::dispatch_thread() at /home/zcp/repo_center/doris_master/doris/be/src/util/threadpool.cpp:0 \t11# doris::Thread::supervise_thread(void*) at /var/local/ldb-toolchain/bin/../usr/include/pthread.h:562 \t12# ? \t13# ? , backend=[172.20.50.7](http://172.20.50.7/)') ``` ```cpp auto tablet_schema = std::make_shared<TabletSchema>(); tablet_schema->copy_from(*tablet->tablet_schema()); if (!request.columns_desc.empty() && request.columns_desc[0].col_unique_id >= 0) { tablet_schema->clear_columns(); // TODO(lhy) handle variant for (const auto& column_desc : request.columns_desc) { tablet_schema->append_column(TabletColumn(column_desc)); } } RowsetSharedPtr rowset_to_add; // writes res = _convert_v2(tablet, &rowset_to_add, tablet_schema, push_type); if (!res.ok()) { LOG(WARNING) << "fail to convert tmp file when realtime push. res=" << res << ", failed to process realtime push." << ", tablet=" << tablet->tablet_id() << ", transaction_id=" << request.transaction_id; Status rollback_status = _engine.txn_manager()->rollback_txn(request.partition_id, *tablet, request.transaction_id); // has to check rollback status to ensure not delete a committed rowset if (rollback_status.ok()) { _engine.add_unused_rowset(rowset_to_add); } return res; } // add pending data to tablet if (push_type == PushType::PUSH_FOR_DELETE) { rowset_to_add->rowset_meta()->set_delete_predicate(std::move(del_preds.front())); del_preds.pop(); } ```
