Bug: when a search timed out we got the generic failbooru page instead
of the search timeout error page.
Cause: when rendering the <link rel="next"> / <link rel="prev"> tags in
the header, we may need to evaluate the search to determine the next or
previous page, but if the searches times out then this fails, which
caused Rails to throw a ActionView::Template::Error because an exception
was thrown while rendering the template.
Likewise, rendering the attributes for the <body> tag could fail with an
ActionView::Template::Error because the call to `current_item.present?`
forced evaluation of the search.
* Fix incorrect canonical tags. Before we were using
`<meta name="canonical" content="...">`. This is wrong, it should have been
`<link rel="canonical" href="...">`.
* Add a default canonical tag on all pages. Fixes Google treating the
same content on different subdomains (safebooru, shima, kagamihara, etc)
as duplicate content. Also fixes Google sometimes treating similar but
distinct content on the same domain as duplicate content.
Fix the wiki excerpt not appearing when searching for a tag that doesn't
exist in the tag list. This could happen if someone created a wiki for a
tag that has never been used on a post.
These exceptions are no longer thrown now that we've switched from
HTTParty to http.rb. Swallowing unexpected exceptions during testing was
a bad practice anyway.
Replace the mocked services in scripts/mocked_services with Rails-level
mocked services.
The scripts in scripts/mocked_services were a set of stub Sinatra
servers used to mock the Reportbooru, Recommender, and IQDBs services
during development. They return fake data so you can test pages that use
these services.
Implementing these services in Rails makes it easier to run them. It
also lets us drop a dependency on Sinatra and drop a use of HTTParty.
To use these services, set the following configuration in danbooru_local_config.rb
or .env.local:
* reportbooru_server: http://localhost:3000/mock/reportbooru
* recommender_server: http://localhost:3000/mock/recommender
* iqdbs_server: http://localhost:3000/mock/iqdb
where `http://localhost:300` is the url for your local Danbooru server
(may need to be changed depending on your configuration).
This passed in development but failed in CI because SavedSearch.redis
used the live Redis server, which worked by accident as long as you had
a Redis server running.
* Combine MissedSearchService, PostViewCountService, and
PopularSearchService into single ReportbooruService class.
* Use Danbooru::Http for these services instead of HTTParty.
Fixes bug described in d3e4ac7c17 (commitcomment-39049351)
When dealing with searches, there are several variables we have to keep
in mind:
* Whether tag aliases should be applied.
* Whether search terms should be sorted.
* Whether the rating:s and -status:deleted metatags should be added by
safe mode and the hide deleted posts setting.
Which of these things we need to do depends on the context:
* We want to apply aliases when actually doing the search, calculating
the count, looking up the wiki excerpt, recording missed/popular
searches in Reportbooru, and calculating related tags for the sidebar,
but not when displaying the raw search as typed by the user (for
example, in the page title or in the tag search box).
* We want to sort the search when calculating cache keys for fast_count
or related tags, and when recording missed/popular searches, but not
in the page title or when displaying the raw search.
* We want to add rating:s and -status:deleted when performing the
search, calculating the count, or recording missed/popular searches,
but not when calculating related tags for the sidebar, or when
displaying the page title or raw search.
Here we introduce normalized_query and try to use it in contexts where
query normalization is necessary. When to use the normalized query
versus the raw unnormalized query is still subtle and prone to error.
Remove the ability to edit an artist's wiki page directly from the
artist edit page. Instead the artist edit page has a link to open the
wiki edit page if you need to edit the wiki too.
Fixes an error being thrown when renaming an artist with a wiki page.
The problem is that changing the artist's name breaks the artist's
association with the old wiki page. Rails really wants nested
associations to be based on immutable IDs, not on mutable names, so
dealing with this correctly is difficult.
We don't really want to encourage people to create wiki pages for
artists to begin with, since they're usually just used to duplicate
the artist urls. Making it less convenient to edit artist wiki pages is
an intentional change to discourage creating unnecessary artist wikis.
Finally, this fixes an exploit where it was possible to edit locked wiki
pages through the artist edit page.
* Refactor fast_count to return nil instead of 1,000,000 if the exact count times out.
* Remove the estimate_post_counts and blank_tag_search_fast_count global config options.
* Replace the hardcoded post count estimates inside fast_count with a
method that parses Postgres's estimated row count from EXPLAIN.
* /counts/posts.json:
** Remove the `raise_on_timeout` parameter.
** Add an `estimate_count=<true|false>` parameter.
** Return null instead of 1,000,000 if the exact count times out.
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.
On the post index page, show the wiki excerpt if the search includes a
single tag, even if the tag is negated or the search includes other
metatags.
If the search includes a single pool: or ordpool: metatag, show the pool
excerpt even if the search includes other metatags.
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.
