BUG: \Neos\Flow\Log\Backend\BackendInterface->close() never gets called

[sjsone]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The close method of logging backends does not get called.

Expected Behavior

The close method should be called somewhere when flow is shutting down. As it is described in the doc-comment:

    /**
     * Carries out all actions necessary to cleanly close the logging backend, such as
     * closing the log file or disconnecting from a database.
     *
     * @return void
     * @api
     */
    public function close(): void;

The PsrLoggerFactory and Neos\Flow\Log\Psr\Logger should both lead to the backends being closed.

Steps To Reproduce

Either create your own logging backend (following the docs) or just add var_dump("closing"); die(); into the close() method of an existing (and used) backend.

Environment

- Flow: 8.3 (but probably since 5)
- PHP: 8.2

Anything else?

Talking to @mhsdesign he discovered that the close method had been called in the DefaultLogger. But that got removed when PSR-3 got fully implemented:

• !!! FEATURE: PSR-3 Logging #1171

• flow-development-collection/Neos.Flow.Log/Classes/DefaultLogger.php

  	public function shutdownObject()
  	{
  	foreach ($this->backends as $backend) {
  	$backend->close();
  	}
  	}
