From: Ben Pfaff Date: Tue, 9 Feb 2010 00:37:49 +0000 (-0800) Subject: ovsdb: Make scalars and 1-element sets interchangeable. X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ae8f13e29057e233712356b3c03f02a7ef4e1e93;p=openvswitch ovsdb: Make scalars and 1-element sets interchangeable. It is natural to write "abc" in place of ["set",["abc"]] and vice versa. I cannot think of a reason not to support this, and it can make reading and writing OVSDB files and transactions easier, so support it. --- diff --git a/lib/ovsdb-data.c b/lib/ovsdb-data.c index 47d1ea74..08d623a5 100644 --- a/lib/ovsdb-data.c +++ b/lib/ovsdb-data.c @@ -897,26 +897,17 @@ ovsdb_datum_from_json(struct ovsdb_datum *datum, { struct ovsdb_error *error; - if (ovsdb_type_is_scalar(type)) { - datum->n = 1; - datum->keys = xmalloc(sizeof *datum->keys); - datum->values = NULL; - - error = ovsdb_atom_from_json(&datum->keys[0], &type->key, - json, symtab); - if (error) { - free(datum->keys); - } - return error; - } else { + if (ovsdb_type_is_map(type) + || (json->type == JSON_ARRAY + && json->u.array.n > 0 + && json->u.array.elems[0]->type == JSON_STRING + && !strcmp(json->u.array.elems[0]->u.string, "set"))) { bool is_map = ovsdb_type_is_map(type); const char *class = is_map ?
