Huh - http://test2.wikipedia.org/w/index.php?title=Template:Orphan&action=edit&mo bileaction=toggle_view_mobile is not a URL that should ever get exposed, and from poking around I can't figure out where this would have come from. URLs with 'mobileaction=toggle_view_mobile' should only ever appear on wikis that do not have a mobile-specific subdomain configured. I wonder if someone created this manually. Regardless, the infinite loop should not be happening and I suspect it's happening because MobileFrontend does not expect to see mobileaction=toggle_view_mobile on a wiki with a mobile-specific subdomain. I am digging into it now.
I am not seeing the behavior on wikipedias. I believe this was introduced by https://gerrit.wikimedia.org/r/#/c/114392/1 The scope of this problem theoretically ought to be small, since URLs that trigger this behavior are not being exposed anywhere (at least that I could find). Bryan, do you have any way of confirming that the scope here is relatively small?
It does not seem to be widespread yet, but the 1.23wmf16 branch is only on the group 0 wikis at the moment. fluorine:~ bd808$ fgrep toggle_view_mobile /a/mw-log/*.log /a/mw-log/api.log:2014-02-28

Alright, I can't gracefully fix this without some consultation from the Zero team, so the change that introduced this bug is reverted (but not deployed): https://gerrit.wikimedia.org/r/#/c/116174/
Merged, deployed. All seems OK now.
