From a0fa0117a5ad728b6f85a39cc52006736f54f90e Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 30 Dec 2002 15:21:23 +0000 Subject: Better solution to integer overflow problem in hash batch-number computation: reduce the bucket number mod nbatch. This changes the association between original bucket numbers and batches, but that doesn't matter. Minor other cleanups in hashjoin code to help centralize decisions. --- src/include/executor/nodeHash.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/include') diff --git a/src/include/executor/nodeHash.h b/src/include/executor/nodeHash.h index c30073ec8cf..02e56355263 100644 --- a/src/include/executor/nodeHash.h +++ b/src/include/executor/nodeHash.h @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2002, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $Id: nodeHash.h,v 1.27 2002/12/05 15:50:37 tgl Exp $ + * $Id: nodeHash.h,v 1.28 2002/12/30 15:21:23 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -30,6 +30,7 @@ extern void ExecHashTableInsert(HashJoinTable hashtable, extern int ExecHashGetBucket(HashJoinTable hashtable, ExprContext *econtext, List *hashkeys); +extern int ExecHashGetBatch(int bucketno, HashJoinTable hashtable); extern HeapTuple ExecScanHashBucket(HashJoinState *hjstate, List *hjclauses, ExprContext *econtext); extern void ExecHashTableReset(HashJoinTable hashtable, long ntuples); -- cgit v1.2.3
