Bug Report

Q	A
BC Break	no
Version	2.11.0

Summary

When updating an app to ORM 2.11 and changing an existing string field to use enums, when the field has a default value, the proxy is incorrectly generated and results in errors similar to "ReflectionException: Class "App\Entity\Card\App\Suit" does not exist." This is because the proxy class doesn't have the leading slash to make it a FQCN, so it's treated as a relative namespace when accessed later.

Current behavior

The proxy class' $lazyPropertiesDefaults array dumps defaults with a class name that's not fully qualified, resulting in a value that's perceived as a relative namespace path.

How to reproduce

Clone https://github.com/mbabker/proxy-generator-bug
Run composer install
Run vendor/bin/doctrine orm:generate-proxies
Inspect the generated proxy in the proxies folder

Expected behavior

The $lazyPropertiesDefaults array should use fully qualified class names to avoid class not found errors, or if it cannot support enums with lazy loading, the proxy generator skips the field.

As a temporary workaround, I can move these default assignments to the class constructor.

Doubtful, anything meaningful is going to require more engine knowledge than I have.

I can monkey-patch the ProxyGenerator so it doesn't consider enums as a lazy-loadable property:

diff --git a/lib/Doctrine/Common/Proxy/ProxyGenerator.php b/lib/Doctrine/Common/Proxy/ProxyGenerator.php
index f71cb915..29e0de4a 100644
--- a/lib/Doctrine/Common/Proxy/ProxyGenerator.php
+++ b/lib/Doctrine/Common/Proxy/ProxyGenerator.php
@@ -980,6 +980,12 @@ EOT;
                 continue;
             }
 
+            if (function_exists('enum_exists')) {
+                if (!$property->getType()->isBuiltin() && enum_exists($property->getType()->getName())) {
+                    continue;
+                }
+            }
+
             $properties[] = $name;
         }

But, getting it to actually support enums is where my skills end. The issue looks to be in how var_export() exports things and I don't have the engine or regex knowledge to be able to mess with that output and get it to fix things.

Can confirm that the issue is with var_export. Ex:

<?php

namespace Proxies;

class AProxy {
    public static $lazyPropertiesDefaults = array (
  'suit' => 
  App\Suit::Hearts,
);
}

Simplified version of what ProxyGenerator is generation

Possible solution could prefix with preg_replace()
