`normalize_query` is used in certain places on the post index page where
we don't want to pay the cost of looking up tag aliases (namely inside
fast_count, in post_search_count_js, and in tag change notices). Don't
normalize aliases by default unless we need to.
Several fixes for the "This tag is under discussion" notice on the post
index page:
* Fix the notice appearing for BURs that aren't pending.
* Fix the notice never going away because of the cache never expiring.
* List all topics when a tag is involved in multiple BURs.
* Link to the forum post instead of the forum topic (fix#4421).
* Optimization: don't check for BURs when the search isn't a simple
single tag search.
* Add a `tags` field to the bulk update requests table for tracking all
tags involved in the request (excluding tags in mass updates that are
negated/optional/wildcards). Known issue: doesn't handle tag type
prefixes in mass updates correctly (e.g. `mass update foo -> artist:bar`
doesn't detect the tag `bar`).
* Allow searching the /bulk_update_requests page by tags.
We don't really need to cache the notice here, but we do it anyway to
reduce queries on the post index page.
Treat the following searches as literal text searches instead of as
special keywords:
* source:none
* commentary:true
* commentary:false
* commentary:translated
* commentary:untranslated
Fix order:custom not working. Also change order:custom to return no
posts under the following error conditions:
* {{order:custom}} (id metatag isn't present)
* {{id:42 order:custom}} (id metatag isn't a list)
* {{id:>42 order:custom}} (id metatag isn't a list)
* {{id:1,2 id:2,3 order:custom}} (id metatag is present twice)
Bug: If a Member had the hide_deleted_posts option turned on and did a
two tag search, no pages would show up.
Cause: The hide_deleted_posts option implicitly adds the -status:deleted
tag, but this tag wasn't considered a free metatag, so this caused
Post.fast_count to fail and return zero because the search was treated
as a three tag search.

* Move various search parser helper methods (`has_metatag?`,
`is_single_tag?` et al) from PostSets and the Tag model to
PostQueryBuilder.
* Fix various minor bugs stemming from trying to check if a search query
contains certain metatags using regexes or other adhoc techniques.
* Make scan_query, parse_query, normalize_query into instance methods
instead of class methods. This is to a) clean up the API and b)
prepare for moving certain tag utility methods into PostQueryBuilder.
* Fix a few cases where a caller used scan_query when they should have
used split_query or parse_tag_edit.
* Support negating the child: and embedded: metatags.
* Fix approver:<any|none>, disapproved:<reason>, commentary:<type> being
case sensitive.
* Fix child:garbage, locked:garbage, embedded:garbage returning all
posts instead of no posts.
* Fix not being able to use source:, locked:, or -id: twice in the same
search.
* Fix not being able to use the status: metatag twice in the same search.
* Fix status:active excluding banned posts.
* Fix status:garbage returning all posts.
Support exclusive ranges for numeric metatags. For example, `id:5...10`
is equivalent to `id:>=5 id:<10`. Useful for splitting searches into id
ranges without the endpoints overlapping: id:100...200, id:200...300,
id:300...400.
Support using the same numeric-valued metatag twice in the same search.
Numeric-valued metatags are those taking an integer, float, filesize, or
date argument. Previously using the same metatag twice would cause the
second metatag to overwrite the first metatag.
Examples:
* "id:>5 id:<10"
* "width:>500 width:<1000"
* "date:>2019-01-01 date:<2020-01-01"
Support using quoted values with all metatags. For example: user:"blah blah",
pool:"blah blah", commentary:"blah blah", etc. Things like rating:"safe",
id:"42" also work. Both single and double quotes are supported.
Also make the status: and rating: metatags fully free. Before only
status:deleted and rating:s were free.
Bug: searching for "filetype:jpg -user:evazion" would negate the
filetype:jpg metatag too. This was because the -user:<name> metatag was
negating the entire cumulative relation instead of just the user:<name>
clause.
Add:
* commentary:true (posts with commentary)
* commentary:false (posts without commentary)
* commentary:translated (posts with translated commentary)
* commentary:untranslated (posts with untranslated commentary)
* commentary:"text" (posts where any commentary field matches "text")
Known issues:
* There's no way to escape the true, false, translated, or
untranslated keywords to do a literal text search for commentaries
containing one of these keywords.
* Negated searches may be slow. Using a left outer join instead of a
subquery would be faster in most cases, but negating it is harder.
* Fix fav:<user> searches to return no results instead of raising a
UserPrivilege error when the user has private favorites.
* Fix fav:<nonexistent_user> raising a UserPrivilege error instead of
returning no results.
* Fix -ordfav:<user> not being supported.
Change favgroup:<name> searches to return no results instead of raising
a UserPrivilege error when an unpermitted user searches for a private
favgroup.
Partial fix for #4389.
Partial fix for #4389.
* Fix invalid username searches returning all posts instead of no posts.
* Fix "user:A user:B" returning results for user:B instead of no results.
* Fix "approver:A approver:B" returning results for approver:B instead of no results.
* Add support for negated -commenter, -noter, -noteupdater, -upvote, -downvote metatags.
* Add support for "any" and "none" values for all username metatags,
including negated metatags that didn't support "any" or "none" before.
* Change noter:any and commenter:any to include posts with deleted notes
or comments. Note that commenter:<username> already included deleted
comments before. This is so that commenter:any has the same behavior
as commenter:<username>
* Fix corrupted image detection. We were shelling out to vips and trying
to grep for error messages, but the error message for jpeg files changed.
Now we load the file in ruby vips, which raises an error on failure.
* Don't attempt to redownload corrupted images. If a download completes
without any errors yet the downloaded file is corrupt, then something is
wrong at the source and redownloading is unlikely to help. Let the
upload fail and the user retry if necessary.
* Validate that all uploads are uncorrupted, including files uploaded
from a computer, not just files uploaded from a source.
* Make IP bans soft deletable.
* Add a hit counter to track how many times an IP ban has blocked someone.
* Add a last hit timestamp to track when the IP ban last blocked someone.
* Add a new type of IP ban, the signup ban. Signup bans restrict new
signups from editing anything until they've verified their email
address.
Use validations instead of raising an exception when the password is
incorrect so that the controller can display errors sensibly.
Also fix users being logged out even when the deletion attempt failed
due to an incorrect password.
Name changes for deleted users are already visible to mods, so the only
thing we need to do here is to generate a name change before the user is
deleted.
* Allow tagging a post with a `disapproved:<disinterest|breaks_rules|poor_quality>` to disapprove it.
* Disallow disapproving active posts.
Fixes#4384.
