It was disabled as part of https://gerrit.wikimedia.org/r/#/c/158409/ - not sure why. But September 2014... Was that around the time it was being migrated to silver? Maybe they imported all the wikitech data but it didn't have the tables for the newly expected-by-default extensions, or something.

BF doesn't require any database tables, just a working job queue.

Which updates a betafeatures_user_counts table?

Oops, I'm tired, ignore me.

And do we currently have a working job queue for wikitech?

krenair@silver:~$ mwscript showJobs.php labswiki --group
refreshLinksPrioritized: 0 queued; 507 claimed (0 active, 507 abandoned); 0 delayed
categoryMembershipChange: 0 queued; 1 claimed (0 active, 1 abandoned); 0 delayed

sudo -u www-data crontab -l shows:

# Puppet Name: run-jobs
* * * * * /usr/local/bin/mwscript maintenance/runJobs.php --wiki=labswiki > /dev/null 2>&1

I am reviving this task slightly. I could definitely use the VisualEditor to edit wikitext which is only available as a BetaFeature ( https://www.mediawiki.org/wiki/2017_wikitext_editor ).

From the above comments about BetaFeatures:

Why it is disabled

Extension has been disabled with other extensions by @Andrew in 2014: https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/158409 . Some got enabled again afterward such as Math.

MediaWiki jobs

Running job is done by running runJobs.php every minute:

    systemd::timer::job { 'wikitech_run_jobs':
        ensure                    => present,
        description               => 'Run Wikitech runJobs.php maintenance script',
        command                   => "/usr/local/bin/mwscript maintenance/runJobs.php --wiki=${wikidb}",
        interval                  => {
          'start'    => 'OnCalendar',
          'interval' => '*-*-* *:*:00', # Every minute
        },
...
    }

It is not ideal but that does the work.

Database table

The extension requires a Database table to be created: betafeatures_user_counts. It is present on the database:

mwmaint1002:~$ echo 'SHOW CREATE TABLE betafeatures_user_counts \G'|sql labswiki
*************************** 1. row ***************************
       Table: betafeatures_user_counts
Create Table: CREATE TABLE `betafeatures_user_counts` (
  `feature` varchar(255) NOT NULL,
  `number` int(11) NOT NULL DEFAULT 0,
  PRIMARY KEY (`feature`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

And match the schema provided in the extension:

CREATE TABLE /*_*/betafeatures_user_counts (
  feature VARCHAR(255) NOT NULL,
  number INT DEFAULT 0 NOT NULL,
  PRIMARY KEY(feature)
) /*$wgDBTableOptions*/;

Maybe some features would require extra database tables, but we can probably assume they got created as part of enabling those extensions.

So I guess it is all a matter of enabling it again?
