From 1f7ef548ec2e594fa8766781c490fb5b998ea46b Mon Sep 17 00:00:00 2001 From: Teodor Sigaev Date: Wed, 28 Jun 2006 12:00:14 +0000 Subject: Changes * new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php) * possible call pickSplit() for second and below columns * add spl_(l|r)datum_exists to GIST_SPLITVEC - pickSplit should check its values to use already defined spl_(l|r)datum for splitting. pickSplit should set spl_(l|r)datum_exists to 'false' (if they was 'true') to signal to caller about using spl_(l|r)datum. * support for old pickSplit(): not very optimal but correct split * remove 'bytes' field from GISTENTRY: in any case size of value is defined by it's type. * split GIST_SPLITVEC to two structures: one for using in picksplit and second - for internal use. * some code refactoring * support of subsplit to rtree opclasses TODO: add support of subsplit to contrib modules --- contrib/tsearch2/gistidx.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'contrib/tsearch2/gistidx.c') diff --git a/contrib/tsearch2/gistidx.c b/contrib/tsearch2/gistidx.c index 7cc370bf84f..5afb1a41b3b 100644 --- a/contrib/tsearch2/gistidx.c +++ b/contrib/tsearch2/gistidx.c @@ -1,4 +1,4 @@ -/* $PostgreSQL: pgsql/contrib/tsearch2/gistidx.c,v 1.13 2006/03/11 04:38:30 momjian Exp $ */ +/* $PostgreSQL: pgsql/contrib/tsearch2/gistidx.c,v 1.14 2006/06/28 12:00:06 teodor Exp $ */ #include "postgres.h" @@ -202,7 +202,7 @@ gtsvector_compress(PG_FUNCTION_ARGS) retval = (GISTENTRY *) palloc(sizeof(GISTENTRY)); gistentryinit(*retval, PointerGetDatum(res), entry->rel, entry->page, - entry->offset, res->len, FALSE); + entry->offset, FALSE); } else if (ISSIGNKEY(DatumGetPointer(entry->key)) && !ISALLTRUE(DatumGetPointer(entry->key))) @@ -225,7 +225,7 @@ gtsvector_compress(PG_FUNCTION_ARGS) retval = (GISTENTRY *) palloc(sizeof(GISTENTRY)); gistentryinit(*retval, PointerGetDatum(res), entry->rel, entry->page, - entry->offset, res->len, FALSE); + entry->offset, FALSE); } PG_RETURN_POINTER(retval); } @@ -242,7 +242,7 @@ gtsvector_decompress(PG_FUNCTION_ARGS) gistentryinit(*retval, PointerGetDatum(key), entry->rel, entry->page, - entry->offset, key->len, FALSE); + entry->offset, FALSE); PG_RETURN_POINTER(retval); } -- cgit v1.2.3
