populateUserTable.php in mediawiki/tools/grabbers is setting `user`.`user_touched`=0, breaking some extensions
Closed, ResolvedPublicBUG REPORT


Steps to Reproduce:

Install the and a blank local MW1.31 installation. Run the scripts to grab text, files, logs or other content. Run php maintenance/populateUserTable.php to generate the "stub" user entries reserving any names that belonged to users on the original wiki.

Take a look at the user table ( SELECT * FROM user ) in SQL; the user.user_touched field will contain 0 (which is not a valid date, unless you were born in a manger in Bethlehem).

Any of the related extensions which attempt to update these records will throw errors because of the bogus zero (0) date.

Actual Results:

MWException from line 4158 of ...//includes/user/User.php: CAS update failed on user_touched for user ID '0000' (read from master); the version of the user to be saved is older than the current version.

Expected Results:

To obtain the expected result (the system attempts to log the user in instead of throwing errors once a password is supplied), just update user.user_touched='20000101010101' (or some other valid date suitably far in the past) and try to log in.

Is there any particular reason why we shouldn't just be setting the user_touched to time-of-running-script, since we're basically touching everything everywhere while we're doing all this anyway?

Although we haven't been running into anything like this that I know of with MediaWikiAuth on 1.32, and I don't think we modified populateUserTable at all - so it's also possible whatever core issue this is triggering might have been fixed in 1.32? Or maybe the MWA approach is different? (It's not actually merged yet, see

Eh, okay, looks like master is going to barf all over on an invalid timestamp regardless. Which probably makes sense - why in the world wouldn't you normally have one?

So we definitely need to set it to something here.
