MobileFrontend throws ConfigException when loading JS
Closed, ResolvedPublic


When trying out mediawiki 1.33, i am seeing:

/w/load.php?lang=en&modules=startup&only=scripts&skin=timeless   ConfigException from line 53 of /srv/mediawiki/w/includes/config/GlobalVarConfig.php: GlobalVarConfig::get: undefined option: 'EnableBlockNoticeStats'

In the logs, but in the js console i see "[6517215b23165c93329a295e] 2019-06-08 16:36:35: Fatal exception of type "ConfigException"".

yup, found the commit that removes it on the master branch in MF, just not a easy back port as one of the files were renamed (

Change 515719 had a related patch set uploaded (by Paladox; owner: Dmaza):
[mediawiki/extensions/MobileFrontend@REL1_33] Remove block notice tracking

To clarify how it happened: the patch was backported, but the patches it relies on, that were marked with 'Depends-On' (in VisualEditor, and MobileFrontend – T225359) were not.
This probably should not have been possible, the 'Depends-On' should check only changes in the same branch. This is apparently already known as T210685: Depends-On should not work across branches.

I believe this should be tracked separately from T225354, because I was just able to get the patch for that issue to merge, while the patch here is still failing.

We won't block the release of MW core on a MobileFrontend issue.

I added a warning to the MobileFrontend and MediaWiki 1.33 pages about the incompatibility since this extension may be considered system relevant for many wikis.

Reedy assigned this task to Paladox.

Force merged the patch... Tests possibly not being fully right on REL1_33 is better than the whole extension actually being broken

Thanks a lot! This specific error no longer appears. I have removed the respective notes from the wiki.
