Description

Following the deployment of T300263: [IP Masking] Create temporary account on first edit, IP addresses will be available via the CheckUser extension, specifically the cu_changes table.

We will need to use this information for revealing information about IP addresses to trusted users, via features such as T300289: [IP Masking] IPViewer roles views temporary account users.

However, CheckUser is not deployed to all our production wikis.

We need to know:

Where is CheckUser not deployed?
On these wikis, do IP addresses need to be revealed to trusted users in order to fight vandalism, etc?
If yes, are there any risks with deploying CheckUser on these wikis? How can we mitigate these risks?

Where is CheckUser not deployed?

Beta Cluster, which shouldn't have it.

InitialiseSettings.php

// On in all Production, disabled in all Labs; varied for Labs only.
'wmgUseCheckUser' => [
	'default' => true,
],

@JJMC89: Is there a reason why the Beta Cluster does not have checkuser enabled? I've always seen people saying it's deliberately disabled, but I have no idea why this is the case.

Users could access PII without the necessary NDAs. Permissions are basically handed out on request, and the infrastructure doesn't have the same restricted access as the production cluster.

Ah, okay. That makes sense. I guess it's not really possible to disable the ability to assign rights to someone / remove certian rights from existence, so unless that could happen I can see why.

@JJMC89 I heard that there are other WMF production wikis that may not have checkuser installed. Do you know if that is the case?

Only beta (because elevated access is given out more widely, and so is shell/DB access)

https://noc.wikimedia.org/conf/highlight.php?file=InitialiseSettings.php

// On in all Production, disabled in all Labs; varied for Labs only.
'wmgUseCheckUser' => [
	'default' => true,
],

https://noc.wikimedia.org/conf/highlight.php?file=InitialiseSettings-labs.php

		'wmgUseCheckUser' => [
			'default' => false,
		],`

Thanks @Reedy!
