[php-src] Issue #11695: Argument #1 ($dest) must be of type ?GError, null given

Issue: https://github.com/php/php-src/issues/11695 Author: SVGAnimate ### Description The following code: ```php <?php $src = new GError(); //$dest = null; g_propagate_error($dest, $src); var_dump($dest); ``` Resulted in this output: ``` Argument #1 ($dest) must be of type ?GError, null given ``` But I expected this output instead: ``` object(GError)#2 (0) { } ``` <hr /> Hi, I would like to bind the function g_propagate_error(https://docs.gtk.org/glib/func.propagate_error.html) I defined the signature as follows : ```php <?php function g_propagate_error(?GError &$dest, GError $src); ``` I use ?GError because I want to inform the user that he will get a GError type In the source code of the extension I declared my arguments as follows : ```c ZEND_BEGIN_ARG_INFO_EX(arginfo_g_propagate_error, 0, ZEND_SEND_BY_VAL, 2) ZEND_ARG_OBJ_INFO(ZEND_SEND_BY_REF, dest, GError, 1) ZEND_ARG_OBJ_INFO(ZEND_SEND_BY_VAL, src, GError, 0) ZEND_END_ARG_INFO() PHP_FUNCTION(g_propagate_error); ``` And the function : ```c PHP_FUNCTION(g_propagate_error) { zval *z_ref_dest = NULL; zval *z_src = NULL; int check_null = 1;//ZVAL_NULLABLE int deref = 0;// ZVAL_BY_REF ZEND_PARSE_PARAMETERS_START(2, 2) Z_PARAM_OBJECT_OF_CLASS_EX(z_ref_dest, php_g_error_class_entry, check_null, deref) Z_PARAM_OBJECT_OF_CLASS(z_src, php_g_error_class_entry) ZEND_PARSE_PARAMETERS_END(); // .... } ``` FYI, without the type, it works using ```c Z_PARAM_ZVAL_EX2(z_ref_dest, 1, 0, 0) ``` In this case regardless of the parameters (check_null, deref) my variable z_ref_dest will always be initialized unlike Z_PARAM_OBJECT_OF_CLASS_EX I modified Z_PARAM_OBJECT_OF_CLASS_EX to correct the error message (must be of type ?GError, null given) : ```c zend_parse_arg_object(deref ? _arg : &_arg->value.ref->val, &dest, _ce, check_null))) ``` I would like my z_ref_dest variable to either be initialized to IS_NULL (or not ...) So my question is: How do you want it to work? ```c Z_PARAM_OBJECT_OF_CLASS_EX(z_val, ce, check_null, deref) else Z_PARAM_SET_NULL(z_val, deref) ``` or ```c Z_PARAM_OBJECT_OF_CLASS_EX(z_val, ce, check_null, deref, optional) ``` Or did I miss something ### PHP Version master ### Operating System _No response_
