"Doctrine\ORM\Proxy\Autoloader" is deprecated

[Chris53897]

After upgrading doctrine/orm (3.4.3 => 3.5.0) the following deprecation message is new.

User Deprecated: Class "Doctrine\ORM\Proxy\Autoloader" is deprecated. Use native lazy objects instead. (Autoloader.php:74 called by DoctrineBundle.php:130, doctrine/orm#12005, package doctrine/orm)

https://github.com/doctrine/DoctrineBundle/blob/2.15.x/src/DoctrineBundle.php#L130

I guess the solution is to only load it for PHP < 8.4

There are also some others

Calling Doctrine\ORM\Configuration::setProxyDir is deprecated and will not be possible in Doctrine ORM 4.0. (Configuration.php:68 called by getDoctrine_Orm_DefaultConfigurationService.php:40, https://github.com/doctrine/orm/pull/12005, package doctrine/orm)

Calling Doctrine\ORM\Configuration::setProxyNamespace is deprecated and will not be possible in Doctrine ORM 4.0. (Configuration.php:157 called by getDoctrine_Orm_DefaultConfigurationService.php:41, https://github.com/doctrine/orm/pull/12005, package doctrine/orm)

Calling Doctrine\ORM\Configuration::setAutoGenerateProxyClasses is deprecated and will not be possible in Doctrine ORM 4.0. (Configuration.php:123 called by getDoctrine_Orm_DefaultConfigurationService.php:42, https://github.com/doctrine/orm/pull/12005, package doctrine/orm)

All are related with some recently added deprecations in doctrine/orm#12020 and doctrine/orm#12036

I bumped into the same deprecation, and I see in the code that the relevant code part is executed only when the auto_generate_proxy_classes option is true. Now I'm wondering if the option still makes sense with PHP 8.4, and also if the enable_lazy_ghost_objects still makes sense (considering that the changelog for ORM 3.5.0 says it's deprecated)

#1898 should help with the deprecated Configuration class calls. The proxy autoloader is a lot more complicated though so that'll need another PR.

This also affects 3.4.4, unless that's a separate bug. I get either the ORM message or the var-exporter message (sometimes both) no matter what I try in PHP 8.4. I've downgraded to PHP 8.3 to avoid this.

You shouldn't need to downgrade to get rid of any deprecation messages. If they're that much of an issue, you can use the Doctrine Deprecations API to ignore them since you can't directly fix them in your own application right now. In some bootstrapping code somewhere, add this:

Doctrine\Deprecations\Deprecation::ignoreDeprecations(
    'https://github.com/doctrine/orm/pull/12005', // Ignore proxy related deprecations from upstream packages
);

[miqrogroove]

Yes, it's that much of an issue. The messages fill the entire console when calling a single command.
