Trying to open page http://fi.wikipedia.org/wiki/Template:P%C3%A4iv%C3%A4malline causes i timeout. Viewing the source works: http://fi.wikipedia.org/w/index.php?title=Template:P%C3%A4iv%C3%A4malline&action=edit . I Suspect that it has something to do with recursion as there is {{{{PAGENAME}}}} in the source.
That cause an infinite loop: the template is calling itself. So basicly don't use it :o) What are you trying todo exactly ?
It's used to include short summary according of given date to date page. Look for example http://fi.wikipedia.org/wiki/1._tammikuuta . I thought infine loops were hammered out? Also i think brion investigated the page already and got some weird results.
Oh, I get it. For those still staring in confusion, as I was, the trick is that *once used on a page*, {{PAGENAME}} refers to the page *containing* the template, not the template itself. So because {{foo}} causes the inclusion of [[Template:Foo]], not [[Foo]], {{{{PAGENAME}}}} *on anything other than a Template page* includes the *template* with the same name as the current article. i.e. within the article [[Bar]] {{{{PAGENAME}}}} is actually equivalent to {{Template:Bar}}. So that template does make sense, it just eats itself when you view it directly. As for the bug, I wonder if the problem is that the code never checks for a page *directly* including itself, because it seems such an odd thing to happen? Unless, of course, the bug is caused by something else on the page... Oh, and I think there's a possible workaround - if the template wasn't stored in the template namespace (move it to Wikipedia:Päivämalline or something) it wouldn't be trying to include itself any more (it would be trying to include Template:Päivämalline, which then wouldn't exist).
Loop detection seems to have been improved by Brion since 1.4beta6 about a week ago.
Marking as fixed, because none of the revisions of the supplied URL cause a timeout any more (fi now running REL1_4rc1+).
