Reduce indirection. PostSet is basically a collection of helper methods
for rendering the post index page. PostSetPresenter was a set of helper
methods for rendering the tag list on the post index page. These don't
need to be separated.
Make PostQueryBuilder apply aliases earlier, immediately after parsing
the search.
On the post index page there are multiple places where we need to apply
aliases:
* When running the search with PostQueryBuilder#build.
* When calculating the search count with PostQueryBuilder#fast_count.
* When calculating the related tags for the sidebar.
* When tracking missed searches and popular searches for Reportbooru.
* When looking up wiki excerpts.
Applying aliases after parsing ensures we only have to apply aliases
once for all of these things.
We also normalize the order of tags in searches and strip repeated tags.
This is so that we have consistent cache keys for fast_count.
* Fixes searches for aliased tags being counted as missed searches (fixes#4433).
* Fixes wiki excerpts not showing up when searching for aliased tags.
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.
* 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.
Refactor tag scripts to fix multiple issues:
* Errors during tag scripting didn't show the actual error message, just
a generic "There was an error updating post #NNN" message.
* The quick edit form didn't show any error messages at all on failure.
* Thumbnails didn't have all their data attributes properly updated
after the post was updated.
This changes it so that thumbnails have their html fully replaced after
updating. This has the side effect of removing event handlers bound
directly to the thumbnail. A `danbooru:post-preview-updated` event is
fired in case userscripts need to detect when thumbnails are updated.
Add a curated posts page at /explore/posts/curated. Curated posts are
the most favorited posts by contributor-level users (users with
unlimited upload permissions).
Also add an order:curated tag using for use in regular searches.
Add <link rel="prev"> and <link rel="next"> elements to most pages with
pagination. This should work on all index pages, but it won't work for
things like pool or forum topic show pages.
Also remove the <link rel="top"> element (wasn't useful, was just a link
back to the root url).
Allow all users to view and edit artist entries and wiki pages belonging
to banned artists. There was little need to hide these pages from
Members, it was mainly to appease artists who didn't like us even
linking to their sites.
These restrictions also had multiple flaws:
* Banned artist information was still visible in the API.
* It was still possible to edit banned artists using the API.
* It was still possible for unprivileged users to revert banned
artist entries or wiki pages to previous versions.
* The restrictions were inconsistent: in various places they were
either Member-only, Gold-only, or Builder-only.
* Fix og:site to og:site_name.
* Fix open graph properties to use <meta property="...">, not <meta name="...">>
* Set og:type, og:site_name, twitter:site globally (not just on post pages).
* Set og:url.
* Remove unused always-resize-images, report-server <meta> tags from
post show pages.
Change the title of the post index page to look like this:
"Danbooru: Anime Image Board" (for the front page)
"Kantai Collection Art | Danbooru" (for a tag search)
Change the meta description of the front page to look like this:
Danbooru is the original anime image 'booru. Find over 3.75 million
anime pictures categorized by over 100 million tags.
Change the meta description for a tag search to look like this:
Find over 37,168 Azur Lane images on Danbooru. Azur Lane (碧蓝航线)
(벽람항로) is a Chinese shipgirl-themed side-scrolling shoot 'em up
mobile game developed by Shanghai Manjuu and Xiamen Yongshi...
* Add favorite count beneath recommended posts. Clicking the favcount
loads more recommended posts like that post.
* Increase number of recommendations shown on post show page.
* Fix inconsistencies in how wiki pages were linked.
* Link directly to the wiki instead of to a title search that is expected
to redirect to the wiki.
* Add the source (twitter, pixiv, etc) and upload date ("X minutes ago")
to iqdb thumbnails.
* Link the filesize to the full file so you can compare files in new tabs.
* Link the similarity to a iqdb search so you can pivot your search to other posts.
This was used to discourage crawlers from crawling certain pages we
didn't want them to crawl, primarily post searches.
Remove because there are better ways to control crawling. Some of these
links weren't even visible to crawlers anyway. This lets us be
consistent about only applying rel="nofollow" to external links.
Set the thumbnail height to auto instead of 154px so that there's not a
big empty gap beneath thumbnails that aren't 150px high.
This requires setting dimensions on the <img> tag itself so that the
image height is known before loading, otherwise the tooltip will be
mispositioned after the image loads in.
We set the min-width and min-height instead of the <img> width and
height properties because our calculated dimensions are sometimes
off-by-one compared to the actual dimensions. I'm not sure how libvips
calculates the thumbnail dimensions, but this avoids forcing a slightly
wrong aspect ratio, which produces ugly resizing artifacts.
* Add ability to search /post_versions by added tags, removed tags, or
changed tags (added or removed).
* Add 'History' link to the sidebar of the /posts index. This is a
shortcut for a /post_versions search of the current tag.
* Remove `list-style-type: none` rules (this is the default).
* Add `list-bulleted` and `list-inline` utility classes.
* Wrap terms of service and user deletion pages in dtext `.prose` class
so we don't have to redefine basic list styles on these pages.
Fineprint text was variously styled with `.info`, `.tn`, `.hint`, or
`.cost-footnote` css classes. Standardize on `.fineprint` instead. Use
`.hint` only for form hints and `.tn` only for <tn> tags in translation
notes.
Incidentally changes the font size of form hints to 0.8em (was 0.7em)
and the color of fineprint to #888 (was #AAA or #666).
Avoid some queries used in wiki page excerpts:
* Only try to load the artist if the tag is an artist tag.
* Avoid using `exists?` queries for wiki pages.
* Bugfix: don't show wiki excerpts for deleted wikis.
