From: Melanie Plageman Date: Mon, 12 Feb 2024 19:04:48 -0500 Subject: [PATCH v9 05/17] Update BitmapAdjustPrefetchIterator parameter type to BlockNumber BitmapAdjustPrefetchIterator() only used the blockno member of the passed in TBMIterateResult to ensure that the prefetch iterator and regular iterator stay in sync. Pass it the BlockNumber only. This will allow us to move away from using the TBMIterateResult outside of table AM specific code. --- src/backend/executor/nodeBitmapHeapscan.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/backend/executor/nodeBitmapHeapscan.c b/src/backend/executor/nodeBitmapHeapscan.c index 5df3b5ca46..404de0595e 100644 --- a/src/backend/executor/nodeBitmapHeapscan.c +++ b/src/backend/executor/nodeBitmapHeapscan.c @@ -52,7 +52,7 @@ static TupleTableSlot *BitmapHeapNext(BitmapHeapScanState *node); static inline void BitmapDoneInitializingSharedState(ParallelBitmapHeapState *pstate); static inline void BitmapAdjustPrefetchIterator(BitmapHeapScanState *node, - TBMIterateResult *tbmres); + BlockNumber blockno); static inline void BitmapAdjustPrefetchTarget(BitmapHeapScanState *node); static inline void BitmapPrefetch(BitmapHeapScanState *node, TableScanDesc scan); @@ -230,7 +230,7 @@ BitmapHeapNext(BitmapHeapScanState *node) break; } - BitmapAdjustPrefetchIterator(node, tbmres); + BitmapAdjustPrefetchIterator(node, tbmres->blockno); valid = table_scan_bitmap_next_block(scan, tbmres); @@ -341,7 +341,7 @@ BitmapDoneInitializingSharedState(ParallelBitmapHeapState *pstate) */ static inline void BitmapAdjustPrefetchIterator(BitmapHeapScanState *node, - TBMIterateResult *tbmres) + BlockNumber blockno) { #ifdef USE_PREFETCH ParallelBitmapHeapState *pstate = node->pstate; @@ -360,7 +360,7 @@ BitmapAdjustPrefetchIterator(BitmapHeapScanState *node, /* Do not let the prefetch iterator get behind the main one */ TBMIterateResult *tbmpre = tbm_iterate(prefetch_iterator); - if (tbmpre == NULL || tbmpre->blockno != tbmres->blockno) + if (tbmpre == NULL || tbmpre->blockno != blockno) elog(ERROR, "prefetch and main iterators are out of sync"); } return; -- 2.40.1 --7mdtsjmrzitrgzgx Content-Type: text/x-diff; charset=us-ascii Content-Disposition: attachment; filename="v9-0006-table_scan_bitmap_next_block-returns-lossy-or-exa.patch"
