From 98efa5ebf0b44d9b5ac7ba0dccff3e4870b4d3c9 Mon Sep 17 00:00:00 2001 From: Andrew Dunstan Date: Wed, 25 Oct 2017 07:34:00 -0400 Subject: [PATCH] Process variadic arguments consistently in json functions json_build_object and json_build_array and the jsonb equivalents did not correctly process explicit VARIADIC arguments. They are modified to use the new extract_variadic_args() utility function which abstracts away the details of the call method. Michael Paquier, reviewed by Tom Lane and Dmitry Dolgov. Backpatch to 9.5 for the jsonb fixes and 9.4 for the json fixes, as that's where they originated. --- src/backend/utils/adt/json.c | 84 +++++++--------------- src/backend/utils/adt/jsonb.c | 97 +++++++------------------ src/test/regress/expected/json.out | 107 ++++++++++++++++++++++++++++ src/test/regress/expected/jsonb.out | 105 +++++++++++++++++++++++++++ src/test/regress/sql/json.sql | 21 ++++++ src/test/regress/sql/jsonb.sql | 22 +++++- 6 files changed, 305 insertions(+), 131 deletions(-) diff --git a/src/backend/utils/adt/json.c b/src/backend/utils/adt/json.c index 2b6a8391d8..a9b40d6d5a 100644 --- a/src/backend/utils/adt/json.c +++ b/src/backend/utils/adt/json.c @@ -17,6 +17,7 @@ #include "access/transam.h" #include "catalog/pg_type.h" #include "executor/spi.h" +#include "funcapi.h" #include "lib/stringinfo.h" #include "libpq/pqformat.h" #include "mb/pg_wchar.h" @@ -2106,10 +2107,17 @@ json_build_object(PG_FUNCTION_ARGS) { int nargs = PG_NARGS(); int i; - Datum arg; const char *sep = ""; StringInfo result; - Oid val_type; + Datum *args; + bool *nulls; + Oid *types; + + /* fetch argument values to build the object */ + nargs = extract_variadic_args(fcinfo, 0, false, &args, &types, &nulls); + + if (nargs < 0) + PG_RETURN_NULL(); if (nargs % 2 != 0) ereport(ERROR, @@ -2123,52 +2131,22 @@ json_build_object(PG_FUNCTION_ARGS) for (i = 0; i < nargs; i += 2) { - /* - * Note: since json_build_object() is declared as taking type "any", - * the parser will not do any type conversion on unknown-type literals - * (that is, undecorated strings or NULLs).
