Problem

  1. Only the Request is persisted across DrupalKernel rebuilds currently, the RequestStack is lost entirely.

There is no need for custom persistence logic for the request stack, we simple can tag the service with the persist tag.

The reason behind special-casing the request service is that we need to cater for the request scope. We do not have this problem with the request stack.

Replaced custom persistence code in DrupalKernel with 'persist' tag on request_stack service.

The other adjustments are still required, since the 'persist' logic only applies to DrupalKernel::updateModules(), but those instances are replacing the DrupalKernel altogether with a new instance.

Grepping for 'new DrupalKernel' yielded another instance of a custom kernel in update.php, which also doesn't use HttpKernel yet.

For completeness, including the grep results:

$ grep -r 'new DrupalKernel' core/
core/includes/bootstrap.inc:  $kernel = new DrupalKernel('prod', drupal_classloader(), !$test_only);
core/includes/bootstrap.inc:    $kernel = new DrupalKernel('prod', drupal_classloader());
core/includes/install.core.inc:  $kernel = new DrupalKernel($environment, drupal_classloader(), FALSE);
core/includes/install.inc:  $kernel = new DrupalKernel('prod', drupal_classloader(), FALSE);
core/scripts/run-tests.sh:  $kernel = new DrupalKernel('testing', drupal_classloader(), FALSE);
core/update.php:$kernel = new DrupalKernel('update', drupal_classloader(), FALSE);
#

Tests for the interactive installer (InstallerTestBase) are calling into rebuildContainer() to boot into the newly installed site environment after installation, but at that point, $this->container still contains the super-minimal container from TestBase::prepareEnvironment(), which does not have request stack.

Attached patch adjusts TestBase::rebuildContainer() for that, including comment to explain the situation.

Back to RTBC, I guess. Only difference in latest patch is the compatibility fix for InstallerTestBase.

Ha, just was about the RTBC that. The fix for the installer test makes sense.

Just to clarify:

@znerol and I briefly discussed whether we could add any sensible tests here.

However, the manual DrupalKernel (re)builds are not worth to test, because pretty much all of them are caused by legacy code that is slated for removal.

If at all, I was thinking about the persistence in DrupalKernel::updateModules(), but that should be covered by 'persist' tag tests already.

Thus, what we're fixing here is essentially just a malformed service definition. There's an upper limit of sensible tests, and an incomplete/incompatible/malformed service definition exceeds that limit.
