Fix an invalid SQL exception that occurs when the paginator tries to
do a COUNT(*) to calculate the page count of a relation that already
includes a GROUP BY + COUNT(*) clause. We need to nest the whole query
inside a `SELECT COUNT(*) FROM (...)` subquery so the inner COUNT(*)
doesn't mess up the outer COUNT(*).
Fixes#4285.
Calling next_page here raises an exception when calculating the page
count because it can't handle SQL containing a GROUP BY clause. Swallow
the exception as a temp fix.
* Add ability to mark dmails as unread.
* Fix users.unread_dmail_count to not count deleted dmails.
* Fix show action so that API calls don't mark dmails as read.
* Don't show the unread dmail notice on the /dmails page itself.
* Stop using users.has_mail flag.
Add <link rel="prev"> and <link rel="next"> elements to most pages with
pagination. This should work on all index pages, but it won't work for
things like pool or forum topic show pages.
Also remove the <link rel="top"> element (wasn't useful, was just a link
back to the root url).
* Fix og:site to og:site_name.
* Fix open graph properties to use <meta property="...">, not <meta name="...">>
* Set og:type, og:site_name, twitter:site globally (not just on post pages).
* Set og:url.
* Remove unused always-resize-images, report-server <meta> tags from
post show pages.
Change the title of the post index page to look like this:
"Danbooru: Anime Image Board" (for the front page)
"Kantai Collection Art | Danbooru" (for a tag search)
Change the meta description of the front page to look like this:
Danbooru is the original anime image 'booru. Find over 3.75 million
anime pictures categorized by over 100 million tags.
Change the meta description for a tag search to look like this:
Find over 37,168 Azur Lane images on Danbooru. Azur Lane (碧蓝航线)
(벽람항로) is a Chinese shipgirl-themed side-scrolling shoot 'em up
mobile game developed by Shanghai Manjuu and Xiamen Yongshi...
Remove links to the aliases and implications pages from the main menu.
Put them in the submenu on the /tags page instead.
These pages are too rarely used to deserve being in the toplevel menu.
They also weren't easy to find for non-Builders. The toplevel menu
shouldn't be dependent on user level.
* Replace /session/new with /login and /session/sign_out with /logout.
* Rename 'sign in' to 'login'.
This changes are to make urls cleaner and terminology more consistent.
Change wiki page search to redirect to exact matches only when using the
quick search bar. Fixes searches sometimes unexpectedly redirecting when
doing a regular (non-quick) search that happens to return a single result.
Also remove the logic that tries to expand the search when no results
are found. This will eventually be replaced with a smarter "did you mean?"
search.
* Factor out common sidebar layout template.
* Convert wiki pages and posts to use this template.
* Add data-layout attribute to <body> element indicating the current layout.
* Remove .ui-corner-all, .ui-state-highlight, .ui-state-error classes
from notice boxes.
* Use .notice, .notice-info, .notice-error classes instead.
* Replace <p> elements in notices with <div>'s so that we don't have to
work around the `margin-bottom: 1em` from <p> elements.
* Replace <h1> elements in notices with <h2>.
* Standardize info notices to use the same shade of light yellow in the
light theme.
Ensure dtext is always wrapped in a `<div class="prose">` or
`<span class="prose">` (for inline dtext) container so that dtext css is
properly applied.
