Refactor the /related_tags.js call so that when the "Related tags"
button is clicked, it only replaces the columns that actually changed,
not the entire related tags section.
This avoids rebuilding the Recent / Frequent / Translated Tags / Artist
columns every time the "Related tags" button is clicked.
Move Post#humanized_essential_tag_string to TagSetPresenter#humanized_essential_tag_string.
This allows humanized_essential_tag_string to reuse the same set of tags
already fetched by the tag set presenter for the sidebar.
This avoids fetching the tag categories from memcache again (via
Post#typed_tags) when we're already fetched the tags once before.
This also means it's no longer necessary to cache humanized_essential_tag_string
itself in memcache, since it can be generated as quickly as the sidebar taglist.
Move PostPresenter#categorized_tag_groups to TagSetPresenter#split_tag_list_text.
This allows split_tag_list_text to reuse the same set of tags already
fetched by the tag set presenter for the sidebar.
This avoids a memcache call to get the tag categories when rendering the
tag string for the post edit form.
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.
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).
