You can avoid these explicit calls to virJSONValueFree() if you declare those variables as g_autoptr() like this: g_autoptr(virJSONValue) ptyc = NULL; g_autoptr(virJSONValue) pyts = NULL; and you can even do that in the inner most blocks where the vars are used.
+ return -1;
Then, this return -1 can be at all those places where 'goto cleanup' is.
