Can't overwrite the default array data if extends [$10 awarded]

[mruz]

I can't set the default array data if extends:

class Test
{

    protected _data = [] { set, get };
}

<?php

class Users extends Test
{

    protected $_data = [
        'id', 
        'username', 
        'password', 
    ];
}

$user = new Users();
var_dump($user->getData())

array(0) { }

Issue related to #520

@ovr any progress on this issue?

[mruz]

Also if Test use eg. Di in the __constructor:

namespace Pro\Di;

use Pro\Di;

class Test
{

    protected _di;

    public function __construct()
    {
            let this->_di = Di::getDefault();
    }
}

I get something like this:

Zephir\CompilerException: Class name: Pro\Users\Di does not exist

It occurs if I set some default attribute as array in the Pro\Users.

This bug is caused because PHP is not support default array value for properties
And we assign default array value in __constructor

It looks like it calls this assign after extends, @ovr could you confirm?

[steffengy]

@mruz Sure it does:
User::construct calls parent::construct (Test::construct),
which it has to ensure that parent properties are set.
(which leads to the behavior you're experiencing)

Can't think of a solution, which wouldn't require refactoring how it currently works.

[mruz]

@steffengy could user construct calls parent construct before user?

Note: Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required. If the child does not define a constructor then it may be inherited from the parent class just like a normal class method (if it was not declared as private).

@sergeyklay @dreamsxin I have a feeling this issue returned. I will check/confirm it later.

Feel free to open a new issue if the problem appears again.
