i am quite sure your code is being called but it doesn't return a

To which function do you refer?
By default, zend_std_get_method is called, and my understanding is
that if no method exists, the zend_class_entry is then checked for a
__call method, and if that doesn't exist, then NULL is returned, and
if NULL is returned, then the call_method handler is called.
My tests show that indeed NULL is returned:
zend_object_handles.c line 650:
zobj = Z_OBJ_P(object);
if (zend_hash_find(&zobj->ce->function_table, lc_method_name,
method_len+1, (void **)&fbc) == FAILURE) {
free_alloca(lc_method_name);
if (zobj->ce->__call) {
zend_internal_function *call_user_call = emalloc(sizeof
(zend_internal_function));
call_user_call->type = ZEND_INTERNAL_FUNCTION;
call_user_call->handler = zend_std_call_user_call;
call_user_call->arg_info = NULL;
call_user_call->num_args = 0;
call_user_call->scope = zobj->ce;
call_user_call->fn_flags = 0;
call_user_call->function_name = estrndup(method_name,
method_len);
call_user_call->pass_rest_by_reference = 0;
call_user_call->return_reference = ZEND_RETURN_VALUE;
return (union _zend_function *)call_user_call;
} else {
printf("get1\n");
return NULL;
}
}
"get1" is printed, however, nothing in my call_method function is
executed, even though other tests show it is indeed apart of the
handler array.
This could only be because of the code I posted earlier, which makes
no use of the call_method handler:
zend_vm_execute.h line 20655:
EX(fbc) = Z_OBJ_HT_P(EX(object))->get_method(&EX(object),
function_name_strval, function_name_strlen TSRMLS_CC);
if (!EX(fbc)) {
zend_error_noreturn(E_ERROR, "Call to undefined method %s::%s
()", Z_OBJ_CLASS_NAME_P(EX(object)), function_name_strval);
}
If I am wrong, please excuse my misunderstanding.
