From 9000faa6ccb3f5bbbd8944590c82826fa13404e9 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Fri, 25 Aug 2017 14:19:23 -0700 Subject: [PATCH 02/16] WIP: Allow tupleslots to have a fixed tupledesc, use in executor nodes. The reason for doing so is that it will allow expression evaluation to optimize based on the underlying tupledesc. In particular it allows JITing tuple deforming together with the expression itself. For that expression initialization needs to be moved after the relevant slots are initialized - mostly unproblematic, except in the case of nodeWorktablescan.c. --- src/backend/executor/execMain.c | 2 +- src/backend/executor/execTuples.c | 50 ++++++++++++----- src/backend/executor/execUtils.c | 45 +-------------- src/backend/executor/nodeAgg.c | 42 +++++++------- src/backend/executor/nodeAppend.c | 17 +++--- src/backend/executor/nodeBitmapAnd.c | 14 ++--- src/backend/executor/nodeBitmapHeapscan.c | 43 +++++++------- src/backend/executor/nodeBitmapIndexscan.c | 14 ++--- src/backend/executor/nodeBitmapOr.c | 14 ++--- src/backend/executor/nodeCtescan.c | 20 +++---- src/backend/executor/nodeCustom.c | 16 +++--- src/backend/executor/nodeForeignscan.c | 24 ++++---- src/backend/executor/nodeFunctionscan.c | 26 ++++----- src/backend/executor/nodeGather.c | 3 +- src/backend/executor/nodeGatherMerge.c | 3 +- src/backend/executor/nodeGroup.c | 18 +++--- src/backend/executor/nodeHash.c | 13 ++--- src/backend/executor/nodeHashjoin.c | 25 ++++----- src/backend/executor/nodeIndexonlyscan.c | 28 +++++----- src/backend/executor/nodeIndexscan.c | 49 ++++++++-------- src/backend/executor/nodeLimit.c | 3 +- src/backend/executor/nodeLockRows.c | 15 +++-- src/backend/executor/nodeMaterial.c | 20 +++---- src/backend/executor/nodeMergeAppend.c | 3 +- src/backend/executor/nodeMergejoin.c | 25 ++++----- src/backend/executor/nodeModifyTable.c | 6 +- src/backend/executor/nodeNamedtuplestorescan.c | 18 ++---- src/backend/executor/nodeNestloop.c | 21 ++++--- src/backend/executor/nodeProjectSet.c | 3 +- src/backend/executor/nodeRecursiveunion.c | 40 ++++++------- src/backend/executor/nodeResult.c | 27 +++++---- src/backend/executor/nodeSamplescan.c | 77 ++++++++++---------------- src/backend/executor/nodeSeqscan.c | 56 +++++++------------ src/backend/executor/nodeSetOp.c | 3 +- src/backend/executor/nodeSort.c | 20 +++---- src/backend/executor/nodeSubqueryscan.c | 18 +++--- src/backend/executor/nodeTableFuncscan.c | 25 ++++----- src/backend/executor/nodeTidscan.c | 49 ++++++++-------- src/backend/executor/nodeUnique.c | 3 +- src/backend/executor/nodeValuesscan.c | 18 +++--- src/backend/executor/nodeWindowAgg.c | 6 +- src/backend/executor/nodeWorktablescan.c | 13 ++--- src/include/executor/executor.h | 8 +-- src/include/executor/tuptable.h | 5 +- 44 files changed, 422 insertions(+), 526 deletions(-) diff --git a/src/backend/executor/execMain.c b/src/backend/executor/execMain.c index 2946a0edee..89ef0fc8ee 100644 --- a/src/backend/executor/execMain.c +++ b/src/backend/executor/execMain.c @@ -3290,7 +3290,7 @@ ExecSetupPartitionTupleRouting(Relation rel, * (such as ModifyTableState) and released when the node finishes * processing. */ - *partition_tuple_slot = MakeTupleTableSlot();
