From 25c00833cb694bea1c4fb3caeccbc9a1fb72d6f8 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sat, 19 Nov 2005 02:08:45 +0000 Subject: Add defenses against nulls-in-arrays to contrib/ltree. Possibly it'd be useful to actually do something with nulls, rather than reject them, but I'll just close the hole for now. --- contrib/ltree/_ltree_gist.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'contrib/ltree/_ltree_gist.c') diff --git a/contrib/ltree/_ltree_gist.c b/contrib/ltree/_ltree_gist.c index 0344b6dc134..c4623ec020f 100644 --- a/contrib/ltree/_ltree_gist.c +++ b/contrib/ltree/_ltree_gist.c @@ -76,6 +76,10 @@ _ltree_compress(PG_FUNCTION_ARGS) ereport(ERROR, (errcode(ERRCODE_ARRAY_SUBSCRIPT_ERROR), errmsg("array must be one-dimensional"))); + if (ARR_HASNULL(val)) + ereport(ERROR, + (errcode(ERRCODE_NULL_VALUE_NOT_ALLOWED), + errmsg("array must not contain nulls"))); key = (ltree_gist *) palloc(len); key->len = len; @@ -518,6 +522,10 @@ _arrq_cons(ltree_gist * key, ArrayType *_query) ereport(ERROR, (errcode(ERRCODE_ARRAY_SUBSCRIPT_ERROR), errmsg("array must be one-dimensional"))); + if (ARR_HASNULL(_query)) + ereport(ERROR, + (errcode(ERRCODE_NULL_VALUE_NOT_ALLOWED), + errmsg("array must not contain nulls"))); while (num > 0) { -- cgit v1.2.3
