Convert to an autosave association on urls. This ensures that when we
save the artist we only validate the added urls, not bad urls that we're
trying to remove, and that url validation errors are propagated up to
the artist object.
This also fixes invalid urls being saved in the artist history despite
validation failing (#3720).
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.
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.
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).
Rename Artist#find_all_by_url to url_matches and drop previous
url_matches method, along with find_artists and search_for_profile.
Previously find_artists tried to lookup the url, referer url, and profile
url in turn until an artist match was found. This was wasteful, because
the source strategy already knows which url to lookup (usually the profile
url). If that url doesn't find a match, then the artist doesn't exist.
Make <role>_only methods check the role first and ip bans last. This
avoids hitting the database for anonymous users, since they'll always
fail the is_<role>? check before the ip check.
* Replace AnonymousUser null object with a readonly, unpersisted User object.
* Default always_resize_images to true (previously it was true for
anonymous users, but false for new members).
* Default comment_threshold to -1 for anonymous users (previously it was
0 for anonymous but -1 for new members).
* `legacy_normalize` came from c6012535, which is no longer a problem.
* `normalize_for_search` is only used for "[mass edit]" links
in artist entries. These links are a shortcut for performing a
`-artist_name source:<artist_url> -> artist_name` mass edit to tag
untagged artists, but this won't work for most sites these days.
