Looks like a regression since 1.16.

In deployed code,

http://www.mediawiki.org/wiki/Special:PrefixIndex/File:

and

http://www.mediawiki.org/wiki/Special:PrefixIndex?prefix=&namespace=6

appear identical except the first says "All pages with prefix" and the second says "All pages (File namespace)". Both return the same results, and have the same "next" link: http://www.mediawiki.org/w/index.php?title=Special:PrefixIndex&from=Hack-A-Ton-DC-t-shirt.png&namespace=6

In my local trunk copy, I can see that the first form works as expected but the second form lists no results -- this is probably a regression from changes to make Special:Prefixindex default to not showing results when no prefix has been passed in.

If a namespace is given, this ought to count as having a prefix and thus being ready to go.

Indeed, passing a 'space' or '+' as prefix does return everything like it used to.

(I guess it's trimmed after the validation part)

Looks like this was another regression in r75314 (bug 23923); pages weren't listed if namespace was set but no prefix given.

Fixed in r79851
