Comment 11 for bug 1999598

Performing verification for Focal

I started a fresh new Focal VM and followed the testcase to get symfony installed and configured, as well as docker. The VM is running php7.4 7.4.3-4ubuntu2.15 from -updates.

Upon running the cloned project that reproduces the issue, I see:

$ curl http://127.0.0.1:8000
...
Error:
Typed property Proxies\__CG__\App\Entity\Store::$ must not be accessed before initialization (in __sleep)

  at vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php:626
  at serialize()
     (vendor/symfony/serializer/Normalizer/AbstractObjectNormalizer.php:626)

  at Symfony\Component\HttpKernel\Kernel->handle()
     (public/index.php:25)
...

I then went and enabled -proposed and upgraded php7.4 to 7.4.3-4ubuntu2.16, and restarted the reproducer.

We now see:

$ curl -I http://127.0.0.1:8000
HTTP/1.1 200 OK

The issue no longer reproduces.

Additionally, looking at the php testcase added to the source tarball, we see during build of 7.4.3-4ubuntu2.16 the test passes:

TEST 12251/13940 [ext/standard/tests/serialize/sleep_uninitialized_typed_prop.phpt]
PASS Referencing an uninitialized typed property in __sleep() should be skipped [ext/standard/tests/serialize/sleep_uninitialized_typed_prop.phpt]

The package in -proposed fixes the issue, happy to mark verified for Focal.
