feedrecentchanges returns zero bytes on 1.25wmf4
Closed, ResolvedPublic

Description

Recent-changes feed

https://www.mediawiki.org/w/api.php?action=feedrecentchanges

doesn't return any XML content.

Affected version : MediaWiki 1.25wmf4
All seems well in projects that still run on MediaWiki 1.25wmf3

Same behaviour with the full parametrized link provided by the side link :

https://www.mediawiki.org/w/api.php?hidebots=1&days=7&limit=50&translations=filter&action=feedrecentchanges&feedformat=atom

and through the index.php link :

https://www.mediawiki.org/w/index.php?title=Special:RecentChanges&feed=atom

Not any special-page is affected, for instance

https://www.mediawiki.org/w/index.php?title=Special:NewPages&feed=atom

works well.

Not sure if that's SpecialPages, API or Wikimedia server wonkyness...

CC'ing Brad and Greg, hoping they have an idea how to investigate this.

Brad: Once you're ready with this, let's get it out in a SWAT. Someone can do it this evening for you, probably.

I prepared the backport and put it on the schedule for tomorrow morning, but if someone wants to SWAT it this evening that's fine with me.

Backported, should be working now on all WMF wikis.
