When a search is performed, we cache the post count so we don't have to
calculate it again every time the user switches pages. However, if the
count times out, we didn't cache it before, causing us to do a slow
count on every page load. This usually happens on multi-tag searches
that return a lot of results, `1girl solo` for example.
This changes it so that the count is cached even when it times out. This
will speed up large multi-tag searches.
This also changes it so that the count is cached for a fixed 5 minutes.
Before it was variable based on the size of the count, but this probably
didn't make much difference.
This directory contains library code used through Danbooru. This includes things like defining API clients, dealing with
sources, parsing tag searches, storing and resizing images, and so on.
Many of the files here use the Service Object pattern. Instead of putting complex code in models or controllers, it goes
here, in plain old Ruby objects (POROs). This keeps models and controllers simpler, and keeps domain logic isolated and
independent from the database and the HTTP request cycle.
