PHP Fatal error: Class 'EntityCacheNodeController' not found in includes/common.inc

Me too. It was a development machine so I solved it by replacing the complete database.
If that is not an option you may truncate table registry_file; in your database. See first comment in http://api.drupal.org/api/drupal/includes%21bootstrap.inc/function/regis...

Marking as major priority as it blocks all tests from being run on a site.

Registry Rebuild will probably also be able to help you if you are stuck with this issue, it's also just a workaround though.

I have the same problem after disabling the module.

I had the same issue here. The reason was: Memcached. While i had flushed file_registry I still got this Error. After flushing memcached all went fine.

In my local Terminal (zsh on OSX) I use:
'echo "flush_all" | /bin/netcat 127.0.0.1 11211'

to flush memcached.

I'm not using memcache and so far drush rr and truncating registry_file table haven't helped.

[edit] Scratch that. My problem was user error.

Hi all,
is any reason to not including this to the uninstall process?

thanks

@quiron if someone proposes a patch for adding something to hook_uninstall() I'll look at it.

Running registry_update() should be enough because this will remove files from the registry table(s) which are no longer available because the module providing it got disabled.

Set issue to Needs review as well.

Drupal.org nearly ran into this. It hit staging. Since this unexpectedly & swiftly takes down the site, marking it critical.

Should this also go in _enable/_install?

Is this a duplicate of #2441965: Broken updates due to Classes living in .module files?

I think it is, see you over there.

I'm using both of these patches in production. (though my commit log message on why is not helpful, sorry)

The dev as of 2016-Aug-15 or later, should have the fixes necessary to circumvent this issue.

I'm using these patches in production. helpful for me.
