XTool error when viewing edit counter of certain users
Closed, ResolvedPublic1 Estimated Story PointsBUG REPORT


Quick way to reproduce the error: Go to

"Normal" way to reproduce error:

  1. Go to
  2. Click on "Edit Counter"
  3. Type "Nigos" on field "User"

XTools then spew out this error:

Argument 4 passed to AppBundle\Model\UserRights::setAutoRemovals() must be of the type array, null given, called in /var/www/src/AppBundle/Model/UserRights.php on line 265

I expected the program to provide statistics about the user. (Example of what would I expected)

The username is valid on Wikipedia (, and I have replicated this error on Firefox and Safari. This bug happens to both logged-in and logged-out users. This bug appeared every time I tried, no matter if I have cleared browser's cache.

XTools version: v.3.14.1 (r.a80978e9); Screenshot:

I saw the automated error reports and suspected this might be a widespread issue. Indeed it is. A recent change to how global user rights changes are logged is the culprit. XTools will break for any user who has had global rights changed since December 9. T41045, T138728 and T153322 are the relevant tasks for that change. A fix for XTools is coming ASAP :)

I'll detail what changes were made for others searching Phabricator for answers. After unserializing the log_params:

  • 4::oldgroups is now oldGroups
  • 5::newgroups is now newGroups

Since this is a critical bug fix I'm going to put in Community-Tech's scope.

Immediate issue has been fixed and deployed with v3.14.2. I'm going to leave this open while I investigate if there are any other upcoming breaking changes related to this.

As far as I can tell we're in no immediate danger of further related changes breaking XTools. Closing as no QA is needed here.
