Topic on Extension talk:Auth remoteuser

Heelo,

after migration to Mediwaki 1.38.0 and upgradin extension too, I run into this message :

MWException: CAS update failed on user_touched. The version of the user to be saved is older than the current version.

Backtrace: from ../includes/user/User.php(2813)

Any idea ?

Thanks

You may look at the user_touched field of the user table for that particular user, if it contains a "sane" value. It should be a number-like, "YYYYMMDDHHmmss" (year month day hour minute second), in the past, not null nor empty

For example: 20000101000000

Thanks for your answer, the value stored is 20220603142256 that seems good to me.

I managed to get the extension working again (my configuration below):

 // Load extension
 wfLoadExtension( 'Auth_remoteuser' );
 
 // If account creation by anonymous users is forbidden, then allow
 // it to be created automatically.
 $wgGroupPermissions['*']['createaccount'] = false;
 $wgGroupPermissions['*']['autocreateaccount'] = true;
 
 // Remote source for user name
 $wgAuthRemoteuserUserName = $login;
 
 // Apply once on user creation
 $wgAuthRemoteuserUserPrefs = [
   'realname'    => $name,
   'language'    => 'fr',
   'email'       => $email
 ];
 
 // Apply on each request
 $wgAuthRemoteuserUserPrefsForced = [
   'realname'    => $undefined,
   'email'       => $undefined
 
 ];

in $wgAuthRemoteuserUserPrefsForced I used $undefined which is an undefined var. If I put everything that exist (such as a real var, a string or empty string) I trigger the error. The only way to make it work is to provide a variable that doesn't exist ... but it work as expected in the user profile ...

Yeah it works if I stop using `$wgAuthRemoteuserUserPrefsForced`, but that's not really a solution because I need to use it. It also only happens with one user, and the user table looks totally ordinary.

Any idea what triggers the warning and how to avoid it?

I found out that it only happens if `$wgAuthRemoteuserUserPrefsForced` contains something different than the database, eg. if it has to change something. Runnung in PHP 7.4 right now, maybe this is the reason? Would be suprised if yes…

OMG! I believe I've found the solution! After allowing sysop to change userrights it works:

`$wgGroupPermissions['sysop']['userrights'] = true`

I don't really understand why it doesn't have this right the first place, but…

That solved another problem I had, but not the one we face here. No idea what's happening. I will try to find another solution for updating the user realname and email in the Wiki DB though. :-/

There's a "bureaucrat" user group that has the userrights right by default. sysops usually can do administrative tasks but not change other users' groups, unless you choose to give them that right.

I ended up commenting out in includes/user/User.php the lines 2600-2602 and now everything works like a charm:

throw new MWException( "CAS update failed on user_touched. ". 

"The version of the user to be saved is older than the current version."

);

I don't really understand why, but $dbw->affectedRows() returns 0 even the changes get written to the database this way. It sounds silly to remove the error throwing, but this way the extension works as intended.
