Description

Just updated several wikis to 1.36.0 and now I get PHP Deprecated errors, both in my server php log and when I run maintenance scripts. For example, if I run runJobs.php, I get the following:

This adds about 500MB of noise to the logs of my moderately busy wikis in a 2 week period. It persists under 1.36.1, had hoped that would fix it.

Just to point out it's not necessarily an issue in MW core itself. It could be an issue with the extensions you have installed. There's no enough information in the reported errors to be able to identify them, or potentially fix them.

You are absolutely right. I finally got back to this, and for me it appears to be Semantic Mediawiki that's causing these. The errors stopped for me when I disabled Semantic Mediawiki. I have raised a ticket with them: https://github.com/SemanticMediaWiki/SemanticMediaWiki/issues/5030

I've discovered the deprecated warnings appear when you define the following variables in LocalSettings.php, even if you have no loaded skin or extension:

$wgDBadminuser = 'zzzz;
$wgDBadminpassword = 'zzzz';

Removing them from LocalSettings.php makes the warnings go away. Of course, I can't do that because the normal wiki user doesn't have permission to create/alter/drop tables :)

Paste the warnings? Stack trace (maybe? :P)

Those two $wg aren't touched in execution except in maintenance, installer, tests/phpunit...

Oh, sorry, I though the task was about update.php but I see now it's more broad. In my case, the warnings appear only when running maintenance/update.php:
