with a table that stores up to 1000 rows for each 'expensive' special
page. This can be paged through, reducing the annoyingness of 50 result
limits on the old system.
Rebuilding the cache can be forced by adding "recache=1" URL parameter,
but this will need to be refined with some sort of controls to prevent
abuse.
Added the user realname update to the installer's updater list, also.
the special query pages were pretty much identical. I copy-and-pasted one to
make the one I was working on, and I realized that that was Wrong.
So, I took the common elements and made them into a class, QueryPage.php.
Then, I derived each of the existing special pages from QueryPage, and
overrode places where they differed. This is a Recipe pattern, btw, for
those of you following along at home.
Anyways, the upshot is that the query pages are a lot shorter, with just the
essentials that make them different from other query pages, and there's one
place to make big UI changes for all queries.
