(Whoops, didn't think to look for an open PR that far back since our problem only happens with 3.2.1.) Just by looking at the changes in #20793 it will highly likely solve the error situation since it includes basically the same fix as this PR. The main problem most likely remains however. The 3.2.1 autoloader will still throw |

Created a branch to check #20793 with the new test case from this PR: https://github.com/mpajunen/symfony/tree/validator-warmup-with-20793 Test still fails as expected. And no, my smaller fix probably does nothing for the earlier issue that #20793 is meant to fix. |

Validation cache warmup can fail if the validated classes contain annotations that use constants.
The cause is the autoloader introduced in #20830. Using another autoloader in addition to the default composer one changes the behavior of the annotation reader:
DocParsermay check for constants in undefined classes. With the new autoloader that check causes a\ReflectionExceptionand caching that class fails.This can also cause an error in
LazyLoadingMetadataFactory: If loading a class fails, valuefalsemay remain in theloadedClassesproperty. If that class is a parent of another validated class, merging the parent constraints will now fail.This PR currently includes a fix for the second problem: Invalid state in
LazyLoadingMetadataFactoryis no longer possible. This gets rid of the error, but the cache is still not built correctly as demonstrated by the failing test case. I'm not quite sure how to fix this correctly.Ping @nicolas-grekas
There are still problems to solve:
