From ba2f615cd40d5d809d1a141c7b098e3bd22ff7bb Mon Sep 17 00:00:00 2001 From: ZyX Date: Sat, 16 Jul 2016 02:26:04 +0300 Subject: functests: Test for error conditions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit During testing found the following bugs: 1. msgpack-gen.lua script is completely unprepared for Float values either in return type or in arguments. Specifically: 1. At the time of writing relevant code FLOAT_OBJ did not exist as well as FLOATING_OBJ, but it would be used by msgpack-gen.lua should return type be Float. I added FLOATING_OBJ macros later because did not know that msgpack-gen.lua uses these _OBJ macros, otherwise it would be FLOAT_OBJ. 2. msgpack-gen.lua should use .data.floating in place of .data.float. But it did not expect that .data subattribute may have name different from lowercased type name. 2. vim_replace_termcodes returned its argument as-is if it receives an empty string (as well as _vim_id*() functions did). But if something in returned argument lives in an allocated memory such action will cause double free: once when freeing arguments, then when freeing return value. It did not cause problems yet because msgpack bindings return empty string as {NULL, 0} and nothing was actually allocated. 3. New code in msgpack-gen.lua popped arguments in reversed order, making lua bindings’ signatures be different from API ones. --- src/nvim/api/private/helpers.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/nvim/api/private/helpers.c') diff --git a/src/nvim/api/private/helpers.c b/src/nvim/api/private/helpers.c index 7efa086af2..23d1540e2f 100644 --- a/src/nvim/api/private/helpers.c +++ b/src/nvim/api/private/helpers.c @@ -351,7 +351,7 @@ void set_option_to(void *to, int type, String name, Object value, Error *err) #define TYPVAL_ENCODE_CONV_UNSIGNED_NUMBER TYPVAL_ENCODE_CONV_NUMBER #define TYPVAL_ENCODE_CONV_FLOAT(tv, flt) \ - kv_push(edata->stack, FLOATING_OBJ((Float)(flt))) + kv_push(edata->stack, FLOAT_OBJ((Float)(flt))) #define TYPVAL_ENCODE_CONV_STRING(tv, str, len) \ do { \ -- cgit
