I have fixed the regression test problem. The original psort() NULL handling patch is attached. It made the while() into a for() which is good, but he did not remove the increment at the bottom or the for(), so nkey was being incremented twice in the loop. Fixed it, and now regression looks good to me. I have updated the files in tools/RELEASE_CHANGES to say 6.3, so I think we are ready for some announcement on 6.3 beta, Marc. I recommend you attach the HISTORY file for the release, so people know what is new. --------------------------------------------------------------------------- Index: psort.c =================================================================== RCS file: /usr/local/cvsroot/pgsql/src/backend/utils/sort/psort.c,v retrieving revision 1.33 retrieving revision 1.34 diff -c -r1.33 -r1.34 *** psort.c 1998/01/25 05:14:49 1.33 --- psort.c 1998/01/25 05:18:34 1.34 *************** *** 7,13 **** * * * IDENTIFICATION ! * $Header: /usr/local/cvsroot/pgsql/src/backend/utils/sort/psort.c,v 1.33 1998/01/25 05:14:49 momjian Exp $ * * NOTES * Sorts the first relation into the second relation. --- 7,13 ---- * * * IDENTIFICATION ! * $Header: /usr/local/cvsroot/pgsql/src/backend/utils/sort/psort.c,v 1.34 1998/01/25 05:18:34 scrappy Exp $ * * NOTES * Sorts the first relation into the second relation. *************** *** 1094,1100 **** int result = 0; bool isnull1, isnull2; ! while ( nkey < PsortNkeys && !result ) { lattr = heap_getattr(*ltup, InvalidBuffer, PsortKeys[nkey].sk_attno, --- 1094,1100 ---- int result = 0; bool isnull1, isnull2; ! for (nkey = 0; nkey < PsortNkeys && !result; nkey++ ) { lattr = heap_getattr(*ltup, InvalidBuffer, PsortKeys[nkey].sk_attno, *************** *** 1106,1119 **** &isnull2); if ( isnull1 ) { ! if ( isnull2 ) ! return (0); ! return(1); } else if ( isnull2 ) ! return (-1); ! if (PsortKeys[nkey].sk_flags & SK_COMMUTE) { if (!(result = -(long) (*fmgr_faddr(&PsortKeys[nkey].sk_func)) (rattr, lattr))) result = (long) (*fmgr_faddr(&PsortKeys[nkey].sk_func)) (lattr, rattr); --- 1106,1118 ---- &isnull2); if ( isnull1 ) { ! if ( !isnull2 ) ! result = 1; } else if ( isnull2 ) ! result = -1; ! else if (PsortKeys[nkey].sk_flags & SK_COMMUTE) { if (!(result = -(long) (*fmgr_faddr(&PsortKeys[nkey].sk_func)) (rattr, lattr))) result = (long) (*fmgr_faddr(&PsortKeys[nkey].sk_func)) (lattr, rattr); -- Bruce Momjian maillist@candle.pha.pa.us
