Aura\Di container locked exception question

[Chris Johnson]

Why does the following code throw an exception, but does not throw it if I comment out the first ini_set() and comment in the second.  In both cases, I am not changing the container, although in the first error-causing version, I am getting a value from it.  

The exception message is: "exception 'Aura\Di\Exception\ContainerLocked' with message 'Cannot modify container when locked.'"

```php

<?php


use Aura\Di\Container;
use Aura\Di\ContainerConfig;
use Clx\ConfigIni;


class _Config extends ContainerConfig
{
    public function define(Container $di)
    {
        // read key/value pairs out of configuration file.
        $config = new ConfigIni('local', 'dev.ini');
        foreach ($config->getAll() as $key => $val) {
            $di->values[$key] = $val;
        }
    }


    public function modify(Container $di)
    {
        ini_set('session.cookie_domain', $di->values['cookie_domain']);
        // ini_set('session.cookie_domain', 'localhost');
    }
}

```

Hi Chris,

I probably don't know what may be the reason for accessing config values is restricted.

But this is where it cause the problem 

https://github.com/auraphp/Aura.Di/blob/be6edc07eb3f2277b46b9a19bbe0978178366cee/src/Container.php#L132 

Alternative way is call getInjectionFactory  : 

https://github.com/auraphp/Aura.Di/blob/be6edc07eb3f2277b46b9a19bbe0978178366cee/src/Container.php#L148

and call  getResolver 

https://github.com/auraphp/Aura.Di/blob/be6edc07eb3f2277b46b9a19bbe0978178366cee/src/Injection/InjectionFactory.php#L53

Now you have full access to read these properties from resolver .

https://github.com/auraphp/Aura.Di/blob/be6edc07eb3f2277b46b9a19bbe0978178366cee/src/Resolver/Resolver.php

So here is the code that should work.

$di->getInjectionFactory()->getResolver()->values['cookie_domain']

Hope that helps to resolve your issue.

Thank you
