01333: Pagelist count parameter ignores zero
Description: Pagelist's count parameter fails to limit the listing to zero pages when its count parameter is zero. Instead it lists all pages.
(:pagelist group=Main count=2:)
(:pagelist group=Main count=0:)
Why would anyone ever specify zero for count? Here's one reason: The count might be entered dynamically via a URL request. If we want to suppress the pagelist entirely, we would naturally specify zero for count. Obviously one could instead add conditionals to only show the pagelist if the count is greater than zero, but that complicates the markup. It seems to me when the markup says to show up to zero pages, that's what pagelist should do.

I have reviewed the CalcRange() function and I believe the
count=0 is returning unlimited results by design, similarly to SQL database queries. Imagine someone in a situation opposite to yours, the page displays some results, and a user can dynamically request to show all results. Because this is really embedded into the guts of that function, I'm afraid we cannot change it without potentially breaking some wikis relying on that feature. But as usual, there is a workaround here, see below. --Petko January 29, 2014, at 04:45 PM
(:pagelist group=Main count=9999..9999:)
No results found.
