Refactor the tag set presenter to get both the tag categories and the
tag counts in the same call to the database, instead of getting the
counts from the db and the categories from memcache.
Refactor tag_list_html, split_tag_list_html, and inline_tag_list_html to
take the `show_extra_links` and `current_query` options explicitly,
rather than implicitly relying on CurrentUser or taking `params[:tags]`
from the template.
Allow searching the URL field by regex or by wildcard.
If the query looks like `/twitter/` do a regex search, otherwise if it
looks like `http://www.twitter.com/*` do a wildcard search, otherwise if
it looks like an url do an artist finder search, lastly if it looks like
`twitter` do a `*twitter*` search.
Add these search params:
* /artists?search[<field>]=
* /artists?search[<field>_eq]=
* /artists?search[<field>_not_eq]=
* /artists?search[<field>_like]=
* /artists?search[<field>_not_like]=
* /artists?search[<field>_ilike]=
* /artists?search[<field>_not_ilike]=
* /artists?search[<field>_regex]=
* /artists?search[<field>_not_regex]=
where `<field>` can be `name`, `group_name`, or `other_names`.
Remove these search params:
* /artists?search[name_matches]=
* /artists?search[other_names_match]=
* /artists?search[group_name_matches]=
`/artists?search[<field>_like]=` effectively does the same thing that
these searches did.
Drop support for the following pseudo-metatags in the Name field in the
artists search form:
* name:<name>
* other:<other name>
* group:<group name>
* status:banned
* status:active
* http://www.example.com
Instead, make the Name field do a wildcard search against the artist
name, group name, or other names. If the query looks like `/regex/`,
then do a regex search against any of these names.
/artists?search[name] now does a literal exact match and
/artists?search{any_name_matches] does the above wildcard/regex search.
* Move the limit:<n> / order:random metatag parsing from the controller
to the post set.
* Introduce `Tag.has_metatag?` and use it to parse these metatags
instead of using a regex (#2894).
Fixes the banned IP check not being applied when sending the HEAD
request for is_cloudflare?.
Also fixes the `#size` method not using the uncached url (which meant
the bookmarklet could report the wrong filesize on artstation uploads).
