Switch to the post search engine using the new PostQuery parser. The new
engine fully supports AND, OR, and NOT operators and grouping expressions
with parentheses.
Highlights:
New OR operator:
* `skirt or dress` (same as `~skirt ~dress`)
Tags can be grouped with parentheses:
* `1girl (skirt or dress)`
* `(blonde_hair blue_eyes) or (red_hair green_eyes)`
* `~(blonde_hair blue_eyes) ~(red_hair green_eyes)` (same as above)
* `(pantyhose or thighhighs) (black_legwear or brown_legwear)`
* `(~pantyhose ~thighhighs) (~black_legwear ~brown_legwear)` (same as above)
Metatags can be OR'd together:
* `user:evazion or fav:evazion`
* `~user:evazion ~fav:evazion`
Wildcard tags can combined with either AND or OR:
* `black_* white_*` (find posts with at least one black_* tag AND one white_* tag)
* `black_* or white_*` (find posts with at least one black_* tag OR one white_* tag)
* `~black_* ~white_*` (same as above)
See 4c7cfc73 for more syntax examples.
Fixes#4949: And+or search?
Fixes#5056: Wildcard searches return unexpected results when combined with OR searches
Inline the page footer, news updates, the ban notice, and the user
verification notice into the default layout. This is a micro
optimization to reduce the number of spans reported to the APM.
Don't show deprecated tags in the related tags or translated tags lists
when editing a post. It doesn't make sense to recommended adding tags
that can't be added to the post.
* Deprecated tags can't be added to posts, but existing deprecated tags
in a post won't be removed
* Only empty tags can be marked as deprecated manually
* No tags can be manually undeprecated
** These limits don't apply to admins
* Deprecating or undeprecating a tag will create a new mod action to
prevent people from going rogue
* Added deprecate/undeprecate commands for BURs
* Deprecating a tag via BUR removes all implications to and from it as well
This is necessary for the `commentary:` metatag, which has different
behavior depending on whether the metatag value is quoted. For example,
`commentary:translated` finds translated commentaries, while
`commentary:"translated"` finds commentaries containing the literal word
"translated".
Count the number of commented and noted posts directly, instead of
indirectly by counting the number of posts in a `commenter:<name>` or
`noteupdater:<name>` search. This is faster because it generates
better SQL.
Refactor the `PostQuery::AST#simplify` method to split it into three
methods: `#trim` to eliminate redundant AND and OR clauses, `#simplify`
to expand deeply nested subexpressions, and `#sort` to sort the query
into alphabetical order.
This is so we can normalize queries written by users by parsing and
rewriting them, but without expanding out nested subexpressions, which
can substantially alter the way the query is written.
Fix artist URLs still showing old cached site icons because the URL
didn't change when the file was updated. Use `image_pack_tag` so that
the filename includes the hash, so that the URL changes when the file
changes.
