Problem/Motivation

Simpletest has a hardcode minimum memory of 320mb! Due to #2422019: Don't use reflection for parsing test annotations this is not necessary.

Proposed resolution

  • Reduce recommended memory for simpletest to 192M.
  • Fix run-tests.sh to run PHPUnit tests in forked processes. This means that the parent test-runner does not use lots of memory.
  • Fix abstract MTimeProtectedFileStorageBase to allow concrete implementations to run in parallel

Following these changes the only test that requires more the 128M is Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test . it needs around 130M. This is not surprising since this collects all the d6 migration tests and runs them together.

So only two tests fail at 128M!!!!
Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test - not that surprising given that it is a meta test.
Drupal\Tests\Core\Entity\EntityManagerTest - a PHPUnit test!

Increasing to 192M to see if that is enough.

I think EntityManagerTest is only failing in #1 due to the way we run PHPUnit tests in run-tests.sh.

The attached patch speeds up running the PHPUnit tests by 30 seconds with a concurrency of 8. Atm a PHPUnit test is a blocking :)

In MTimeProtectedFileStorageBase we can't use vfsStream because tempnam() is not supported https://github.com/mikey179/vfsStream/wiki/Known-Issues. Imo this is a bit of a dodgy unit test because it is changing stuff in the temporary file system.

We need to fix the phpunit tests to run in a forked process because running them in the test runner process takes memory.

we have a bunch of reduce memory related issues, but most (seem to be) around install. like #2289201: [Meta] Make drupal install and run within reasonable php memory limits so we can reset the memory requirements to lower levels

Nice, I guess this means that phpunit tests run concurrent now, like other tests? Probably doesn't make much of a difference now, but if make KernelTestBaseV2 happen, it will..
