>Subject: [PATCH] Bug 35129: Return 400 if _per_page=0 passed
>
>This patch adds a safe guard for when consumers pass _per_page=0 to
>endpoints. This condition is checked for on a centralized place and
>avoid reaching the controller in such scenarios that would provoke a
>division by zero exception.
>
>To test:
>1. Apply the regression tests patch
>2. Run:
>   $ ktd --shell
>  k$ prove t/db_dependent/api/v1/pagination.t
>=> FAIL: We expect a 400, but get a 500 instead
>3. Apply this patch
>4. Repeat 2
>=> SUCCESS: Tests pass! No more explosions for this!
>5. Sign off :-D
