How to set values into core_config_data with module setup (Area code is not set)

[bka]

Hi all,

I'm looking for a way to set some configuration values with an InstallData.php script inside a custom module. My current approach to utilize \Magento\Config\Model\Config doesn't seem to work:

public function __construct(\Magento\Config\Model\Config $config, \Magento\Theme\Model\ResourceModel\Theme\CollectionFactory $themeResourceFactory){
  ...
}

When executing bin/magento setup:upgrade it fails with Area code is not set. The underlying issue seems to be that \Magento\Config\Model\Config has a dependency to \Magento\Config\Model\Config\Structure which itself has a dependency to Magento\Config\Model\Config\Structure\Element\Section which depends on a \Magento\Framework\AuthorizationInterface. So it tries to start a new session inside SessionManager.php and obviously dies because Area code is not set.

[Magento\Framework\Exception\LocalizedException]  
Area code is not set

I also tried \Magento\Setup\Model\ConfigModel, but this fails as well.

So what is the preferred way to set some config values like currency/options/base? Is it really necessary to have a dependency to the Auth/Session.php? What would be a proper solution?

I also accidentally discovered that I could work around this by sending some output e.g. having a registration.php with one empty line which causes isSessionExists to return true because
headers_sent is 1.

public function isSessionExists()
{
    if (session_status() === PHP_SESSION_NONE && !headers_sent()) {
        return false;
    }
    return true;
}

Everything works fine under these circumstances because SessionManager.php:start does not run into getAreaCode() because it thinks a session already exists.

public function start()
{
    if (!$this->isSessionExists()) {
        \Magento\Framework\Profiler::start('session_start');

        try {
            $this->appState->getAreaCode();

    ...

But this was obviously not intendent. Is there maybe a way to deactivate Session/Authenticate for setup tasks or am I on the wrong track? Any hints are welcome.

This one can be closed. I found a way: instead of using '''\Magento\Config\Model\Config''', values can be written directly like in Magento_Catalog module. This requires no dependencies to AuthorizationInterface or the SessionManager and seems to work fine.

protected function saveConfigValue($path, $value){
  $data = [
      'scope' => 'default',
      'scope_id' => 0,
      'path' => $path,
      'value' => $value,
  ];
  $this->setup->getConnection()
      ->insertOnDuplicate($this->setup->getTable('core_config_data'), $data, ['value']);
}

...

$this->saveConfigValue("design/header/welcome ", "Welcome")
