Doctrinebundle: fails on clearing cache on PHP 7.2.20 if twig/twig is not installed

[someniatko]

PHP 7.2.20 fixes bug related to autoloading non-existing interfaces: https://bugs.php.net/bug.php?id=76980

Steps to reproduce:
Use PHP 7.2.20. Require this bundle (v1.11.2) in Symfony v4.3. Make sure twig/twig is not required and is not a transitive dependency of any of other packages (e.g. symfony/twig-bundle). Attempt to clear cache (php bin/console cache:clear).

Expected result:
Cache cleared successfully.

Actual result:
PHP Fatal error: During class fetch: Uncaught ReflectionException: Class Twig\Extension\AbstractExtension not found in /path/to/project/vendor/doctrine/doctrine-bundle/Twig/DoctrineExtension.php:13
Stack trace:
(...)

[xabbuh]

Can you please show the stack trace for this exception?

This stacktrace is actually from project with symfony 4.2.9

[xabbuh]

I cannot reproduce this. Can you create a small example application that allows to do so?

[someniatko]

@xabbuh After some debugging i've managed to create minimal reproduction. Now i am not sure if this is bug of this bundle or symfony's dependency-injection component.

You can see an example app here:
https://github.com/someniatko/doctrine-bundle-cache-clear/tree/master

The bug is triggered if there is some interface with more than one implementations, and then this interface is attempted to be used as a service (e.g. in controller's action arguments). Symfony then cannot autowire this service because of ambiguity and should show a user-friendly error message. In order to create such a message, symfony first "populates" all existing service definitions. It happens to be that DoctrineExtension (for twig) is among such definitions.

In Symfony\Component\DependencyInjection\Compiler\AutowirePass#populateAvailableType() there is an expression !$reflectionClass = $container->getReflectionClass($definition->getClass(), false). false means "do not throw an exception on failure". However, an exception is anyway thrown in PHP 7.2.20, but during class autoload stage.

I think some guy from Symfony should look at this, maybe @stof

[vchabot]

Hello,

I have the same issue with PHP 7.2.20 and doctrine-bundle 1.10.2.

I don't have twig/twig required in my project, and the same exception is occuring:

Not sure if it can help, but it always nice to hear that we are not alone with an issue :)

[derrabus]

I can confirm the problem with php 7.2.20 and 7.3.7.

[derrabus]

I've opened symfony/symfony#32395.

[MaryNfs]

similar issue here, I‌ get below error:
PHP Fatal error: During class fetch: Uncaught ReflectionException: Class Symfony\Component\Templating\Helper\Helper not found

even I‌ upgraded PHP from 7.2 to 7.3.7, but the problem still remains.

[alcaeus]

As per https://github.com/php/php-src/commit/22ed362810c1b3a5ecb54ebd1d50d804c7fc3159, the change in PHP that causes this error will be reverted in the next patch releases for 7.2 and 7.3. For PHP 7.4, there needs to be a different solution. However, since this is caused by the DI component, I'd like to wait before working around this here. If this can't be solved in the DI component (which could always handle such incomplete services when they aren't used), then we'll have to change our service configs to only create services that have all their dependencies set. I'm closing this for now until we find a resolution for it in https://github.com/symfony/symfony/issues/32395.

If you use docker just fix your version to php:7.2.19

[LugiHaue]

I was getting this error while using php:7.2-fpm-alpine image in bitbucket pipelines, then i updated image to php:7.3-fpm-alpine and it's worked.

[derrabus]

I did a quick test with php 7.3.8RC1. Cache warmup on @someniatko's reproducer completed without errors.

[khaledalam]

@someniatko PHP 7.3.7-1 worked!

php7.3 bin/console cache:clear
[OK] Cache for the "dev" environment (debug=true) was successfully cleared.

PHP 7.2.20-1 not worked!

[wirwolf]

I have issue after composer update

What about running composer global require symfony/thanks && composer thanks now?
