Some errors after D8 upgrade (Redis)

[zanami]

Just a heads up, I spent some time struggling with this.

1. Thunder 2.13 D8.4 platform, one site
2. Added another platform — Thunder 2.18 (D8.5)
3. Migrated the site via panel, all went fine, task complete, no errors or warnings.
4. Site doesn't work (error 500).
5. drush cr — ok, drush updb — nothing to update

Solved with service redis-server restart (some time later)

I'm sure it's not the best way so maybe it's worth documenting.

BTW I ran into the same problem trying to clone the same site (using the same platform).

Some of the errors

How did you setup the Redis server? I am getting Redis is not connected when I install the Redis module(Drupal8).

[zanami]

I did not. It's installed and used by default by BOA as a part of other common modules (/modules/~o_contrib_eight for D8).

https://github.com/omega8cc/boa/blob/master/docs/MODULES.txt ([NA] means that this module is used without the need to enable it)

Looks like your redis server isn't running or something (like PHP) is misconfigured.

I don't think it's related so you'll have to open a separate issue or look here https://github.com/omega8cc/boa/search?q=redis&type=Issues

Hi @zanami

Thank you for your great response. I've actually solved by not installing the Redis Module on Drupal 8 as BOA has this functionality in place.

To check if it's working you should see X-Allow-Redis: YES when visiting and domain alias that contains .dev. in its name

 if ($redis_up && $use_redis) {
  if ($is_dev && !$is_backend) {
    header('X-Allow-Redis: YES');
  }
}

[omega8cc]

It could be a Redis integration module bug, or even Zend OPcache configuration related, which we have fixed recently in BOA head: https://github.com/omega8cc/boa/commit/8f7b4948ed17159b2bfa29fd6b9706638296715c

The fact that restarting Redis server helped could be a coincidence. But if not, then it does suggests a bug in the integration module, or in our default settings for the module.

I confirm that after an upgrade of a drupal 8 site (Open Social) using composer, the 500 issue arose and was solved with a service redis-server restart.
