I've had trouble [[ https://wikitech.wikimedia.org/wiki/Deployments#deploycal-item-20190306T1200 | yesterday ]] ([[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/494218 | 494218 ]], [[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/494707 | 494707 ]]) and [[ https://wikitech.wikimedia.org/wiki/Deployments#deploycal-item-20190307T1200 | today ]] ([[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/494806 | 494806 ]]) with deploying `dblists/commonsuploads.dblist` during EU SWAT.
Yesterday, I've merged 494218 and pulled it to mwdebug1002, but it did not work, so I've reverted it with 494707.
Today, I've merged 494806 and pulled it to mwdebug1002, but it did not work again. I didn't think it would break anything so I've done a full deployment. It didn't work even then.
@Urbanecm and @MarcoAurelio suggested that touching `wmf-config/InitialiseSettings.php` would help, but I've rejected because it's not documented at [[ https://wikitech.wikimedia.org/wiki/SWAT_deploys/Deployers | SWAT deploys/Deployers ]].
I've decided to deploy a patch that was next in SWAT calendar ([[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/494225 | 494225 ]]) that changes `wmf-config/InitialiseSettings.php` and see if then 494806 would work. To my surprise, 494806 worked after 494225 was deployed.
